Abstract
The utility model relates to an improved handle control line for a semi-gantry crane, and belongs to the technical field of crane equipment. The improved handle control line is used for conveniently and safely controlling a lifting motor of the semi-gantry crane. The technical scheme is as follows: a plurality of line pulleys are arranged on a walking beam of the semi-gantry crane and are uniformly distributed along one side of the walking beam, and one end of the handle control line is connected into a control box of the lifting motor; and the other end of the handle control line sequentially penetrates through the line pulleys, and is downwards connected with a handle control line box from the upper part of a walking rack of the semi-gantry crane. The improved handle control line for the semi-gantry crane has the advantages that the handle control line is changed to be arranged on the walking beam along the line pulleys, so that the handle control line can move along with the lifting motor, and the lifting operation control can be carried out at any position on the ground by operators, so that the security risks brought by the lifting of workpieces can be avoided, and simultaneously, the replacement number of the handle control line can be reduced, and the failure rate can be greatly reduced.
Description
Technical field
The utility model relates to a kind of lifting motor handle control line of semi-goliath crane, belongs to the crane facility technical field.
Background technology
Semi-goliath crane is industrial and mining enterprises' lifting appliances commonly used; General semi-goliath crane lifting motor is to control through the handle control line by standing in ground operating personal; The cabling mode of the handle control line of semi-goliath crane is conventional for directly drawing from the lifting motor control box, like this operating personal must stand in the lifting motor under or the side, if in case workpiece unhook or crooked takes place to lift by crane; Have an accident possibly, therefore have certain potential safety hazard.Improving one's methods in the past is with handle control line lengthening, pulls on the ground, so that operating personal is away from the workpiece of slinging; But control line pulls and is easy on the ground damage; Fault rate is high, also can directly influence lifting operation, therefore necessary the improvement.
The utility model content
The utility model technical matters to be solved provides and a kind ofly can make the operator away from suspension hook, and non-damageable improved semi-goliath crane handle control line.
The technical scheme that solves the problems of the technologies described above is:
A kind of improved semi-goliath crane handle control line; It is that a plurality of cabling pulleys are installed on the walking crossbeam of semi-goliath crane; The cabling pulley is uniformly distributed with along walking crossbeam one side; Handle control line one end is connected in the control capsule of lifting motor, and the other end passes the cabling pulley successively and is connected with handle control line box downwards on the walker top of semi-goliath crane.
Above-mentioned improved semi-goliath crane handle control line, the length of said handle control line adds the summation of walking crossbeam to ground-surface distance greater than the length of walking crossbeam.
The advantage of the utility model is: be laid on the walking crossbeam through the handle control line being changed into along the cabling pulley; Make the handle control line to move along with the lifting motor; Operating personal can carry out lifting operation control in ground-surface optional position; Avoid lifting by crane the potential safety hazard that workpiece brings, can reduce the replacing of handle control line simultaneously, significantly reduce fault rate.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the lateral plan of Fig. 1.
Mark is following among the figure: walker 1, walking crossbeam 2, lifting motor 3, handle control line 4, cabling pulley 5, handle control line box 6.
The specific embodiment
Show among the figure; The utility model is that a plurality of cabling pulleys 5 are installed on the walking crossbeam 2 of semi-goliath crane; Cabling pulley 5 is uniformly distributed with along walking crossbeam 2 one sides; Handle control line 4 one ends are connected in the control capsule of lifting motor 3, and the other end passes the end that cabling pulley 5 arrives the walker 1 of semi-goliath crane successively, and the top from walker 1 is connected with handle control line box 6 downwards then.
In order to make lifting motor 3 can arrive the distal-most end of walking crossbeam 2, the length that the length of handle control line 4 is greater than walking crossbeam 2 adds the summation of walking crossbeam 2 to ground-surface distance.
Adopt this improved semi-goliath crane handle control line, operating personal can ground away from the lifting workpiece situation under to the lifting motor 3 carry out control operation, avoided the generation of accident.Handle control line 4 can not pull on ground simultaneously, has avoided damage yet.
