Lever hoist is a kind of hoisting wire rope drawing tools

Lever hoist is a kind of hoisting wire rope drawing tools, when working by hand pull (handle, alternative action by rocker, connecting rod in the clamping mechanism, driving load forward or backward. Because there is no brake lever hoist wire rope, so the clamping mechanism is grasping mechanism brake mechanism, is the key to this kind of product. Design lever hoist wire rope, the main problem is the design of clamping mechanism is calculated. Since there is no uniform design specification, we are updated according to many years of three generations of the product design, test and manual hoistexperience, the design and calculation method of the following are put forward. These data and the method also can be used for reference in the other wire rope in the design of clamping mechanism. A basic size, clamp, clamp plate calculation of the clamping lever hoist mechanism by the clamp, the clamping plate and pin shaft with clamping plate connections side panel, etc. Pull (forward) the handle, the size of the connecting rod drives the side panel for chainb lock motion, a pair of side panel, the other a pair of side plate back; Forward that lateral plate clamping plate.

mainly used to lifting crane equipped with

Into items, it is mainly used to lifting crane equipped chainb lock appropriate spreader can also after lifting material and liquid material. Crane work is characterized by intermittent movement, that is in a working cycle, to pick up, transport, unloading corresponding mechanism is work alternately. The agencies are often in starting, braking and running manual hoist condition of the positive and negative direction. The classification and features of the crane crane according to the structure classification according to the structure is divided into boom crane type crane and bridge type crane. Crane overview the status quo of hangzhou a manufacturing unit with an electric hoist bridge crane load across a runtime easily occurs in the car derailment problem, the crane lifting weight of 10 (t vice hook for 3 t), lifting height of 8, to 28 m span, the car track is 1600 m, work level for A4, no machine design. The crane has been in operation for more than five years, usually use frequency is higher.

Wire rope electric hoist rope guide

Wire rope electric hoist wire rope electric hoist on the guide rope device for wire rope by the regulation on interval neatly around the drum gear. When the hoist equipment rope device on the drum synchronization with wire rope winding cannot be moved, often guide rope is pulled bad, the phenomenon such as connecting rod were bent. The guide rope device breakdown can make the guide rope device cannot perform the function of the rope, rope pressure, at the chainb lock time may cause height limit is invalid, lead to a lifting accidents. Repair damaged when the guide rope device, replacing arc clamp is very troublesome, and have a certain risk. In this case, the author using TRIZ theory analyses the steel wire rope electric hoist rope guide, gives the solution, and the solution added TRIZ invention principle in the database at the same time. Electric hoist can be used as a heavy equipment used alone, a small driving after also can be used for overhead monorail crane. Is a kind of compact structure, light weight, high efficiency and easy operations of lifting equipment. Specifications of wire rope electric hoist by building height, track type type can be divided into 14 types. Its appearance figure is chosen, and work performance. Type electric hoist wire rope electric hoist the code and the type code of another type of HSG standard building height, linear rail, rigid connection of hand trolley.

Is a wire rope (rod) deep processing products

Made up of many wire twist into a rope used in industry, widely used in all kinds of industrial, mining and transportation. There are many different kinds of steel wire rope, but used in oilfield is a round rope, only have a single or double twist twist, and in the majority with double twist. Double twist rope is wire twist into a, again by a few strands twisted into a steel wire rope, wire rope at the center of both  core, there is also a steel core. With several root manual hoist section shape and the diameter of the wire, according to certain rules as twisting spiral wire bundle. Is a wire rope (rod) deep processing products, in steel wire products occupy a larger proportion. Origin, development and current hoist equipment in the steel wire production before using the hemp rope and chain, was later by organic fiber and metal chain to rub into the low tensile strength of the rope. With metallic ore and coal mining and transportation in the elevator with the development of the hoist machinery, the rope can not meet the requirements, began to replaced by metal wire twist twist wire.

Hand chain hoist is a kind of small manual lifting tool

Hand chain hoist is a kind of small manual lifting tool. Safety, light weight and convenient operation is the goal of the chainb lock of the product. To achieve this goal, according to the characteristics of the chain product structure, reasonable design of the gear is especially important. At present, the chain in gear, mainly is the involute spur gears. Reasonable design of this kind of gear is still the focus of the improvement of involute gear tooth profile, because it is the factors affecting the service life of bearing capacity and the use of involute gear is one of the most main factor. From the manual hoist practice and theoretical analysis shows that the reasonable selection of tooth profile Angle, transition radius and addendum higher tooth shape parameters, the comprehensive improve the bearing capacity and service life of the involute gear has a significant effect. According to the tooth profile Angle, selected a reasonable transition radius and the addendum higher combination parameter, manufacture special gear cutting tools, in the gear processing, is still very economic, the chain of low-value products especially for. Therefore, this article through to the different tooth profile Angle, the transition radius and addendum higher gear tooth profile parameters on the performance analysis and comparison, choose the reasonable parameter values and their combination, as a practical design chain drive gear recommended value.
