Abstract

The utility model discloses a counterweight loading and unloading mechanism for a crane, which comprises two lift cylinders, two locking cylinders, four groups of hanging heavy steel cables and four groups of pulley assemblies. The utility model is not limited by the flat space position of the tyre crane car frame during the loading and unloading process, especially when the total length and the rear overhang of the automobile is strictly constrained, and the engine can not sink. The steel cable and the pulley assembly are used for hoisting with safety and reliability; the steel cable and the balance weight are flexible linkage; the control to the inceptive putting position of the balance weight is not very strict, and is easy operation; the manufacture cost of the entire mechanism is low; the time of the entire control process is short, and the loading is fast. The utility model is a counterweight loading and unloading mechanism for crane, which is not limited by the flat space position of the tyre crane car frame, and has features of safety, easy operation, short control process time and fast loading.

Description

A kind of hoisting crane counterweight handing device

Technical field

The utility model relates to a kind of counterweight handing device, particularly relates to a kind of hoisting crane counterweight handing device.

Background technology

Along with the increase of car hosit tonnage, corresponding counterweight weight has also increased, the increasing of operating mode, cooresponding counterweight is also different under different operating modes, and owing to the qualification of chassis to allowable load, counterweight has to make moving counterweight, be not with counterweight when promptly driving a vehicle, press required installation during work.Certainly the loading and unloading of the existing counterweight of historical facts or anecdotes, promptly must other vehicle or lifting device assist, car hosit self can load and unload counterweight, seems especially important for saving time and cost in practical operation.

The structure of tradition counterweight handing device is that the bilateral symmetry at turntable is provided with lift cylinder, each lift cylinder is provided with oscillating cylinder, on turntable, also be provided with the locking cylinder, its installation steps are: by self loop wheel machine or external loop wheel machine required counterweight is lifted by crane certain position, car hosit vehicle frame plane, by locating dowel pin on the plane counterweight is located.Turntable revolution then, make the turntable afterbody go to the counterweight putting position directly over, positional cylinder stretches out, and inserts bearing, locking bearing, locking turntable.At first be that oscillating cylinder stretches out, after reaching the position, make the some angles of lift cylinder deflection, lift cylinder is stretched out then, after reaching the position, the oscillating cylinder withdrawal makes lift cylinder reply vertical state, lift cylinder withdrawal then, the horizontal axle journal of the piston rod afterbody of lift cylinder contacts with hook portion on the counterweight bearing, lift cylinder continues withdrawal, will be placed on the counterweight bearing counterweight and counterweight bearing and lift from plane on the vehicle frame together, after lift cylinder is reduced to the position, the locking cylinder stretches out, insert in the knock hole on the counterweight bearing, so far, the installation process of counterweight is finished.When unloading counterweight, otherwise as long as with top process.The shortcoming of this traditional counterweight handing device is to be subjected to the restriction of car hosit vehicle frame plane space position especially to be subjected to strict constraint at vehicle length overall, rear overhang, when driving engine can not sink; Lift cylinder and counterweight are rigid attachment, and be strict to the control of the initial putting position of counterweight, and operation is inconvenient, safe reliability is poor; Entire mechanism manufacturing cost height; The whole manipulation process time is long, loads and unloads slower.

The utility model content

It is short that technical problem to be solved in the utility model provides a kind of restriction that is not subjected to car hosit vehicle frame plane space position, safety, reliable, easy operating, low cost of manufacture, manipulation process time, loads and unloads hoisting crane counterweight handing device efficiently.

In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of hoisting crane counterweight handing device, comprise turntable, it is characterized in that: be provided with left lift cylinder and right lift cylinder in described turntable bilateral symmetry, a described left side, the piston rod of right lift cylinder is respectively equipped with left movable pulley and right movable pulley upwards and on its top, be provided with left side fixed pulley and right side fixed pulley in described turntable bilateral symmetry, left steel rope one end around the assembly pulley of being made up of described left movable pulley and left side fixed pulley is packed on the described turntable, and the other end is provided with left lift heavy hook; Right steel rope one end around the assembly pulley of being made up of described right movable pulley and right side fixed pulley is packed on the described turntable, and the other end is provided with right lift heavy hook, also is provided with left and right locking cylinder in described turntable both sides.

As a kind of improvement of the present utility model, be provided with voussoir in described turntable bottom, be used for guiding and location.

Adopt the hoisting crane counterweight handing device of technique scheme, in handling process, be not subjected to the restriction of car hosit vehicle frame plane space position, especially be subjected to strict constraint, when driving engine can not sink at vehicle length overall, rear overhang; Utilize steel rope, assembly pulley lifting, safety, reliable, steel rope connects for flexible with counterweight, and is so not strict to the control of the initial putting position of counterweight, easy operating; The entire mechanism low cost of manufacture; The whole manipulation process time is short, and loading and unloading are quick.

In sum, the utility model be a kind of restriction that is not subjected to car hosit vehicle frame plane space position, safety, reliable, easy operating, low cost of manufacture, manipulation process time short, load and unload hoisting crane counterweight handing device efficiently.
