Abstract
The utility model provides a hoisting mechanism of an asphalt pavement maintenance truck. The mechanism mainly solves the problem that the existing asphalt pavement maintenance truck cannot carry heavy objects. The hoisting mechanism of the asphalt pavement maintenance truck comprises a column fixedly arranged on a truck platform, and a hoisting machine for lifting is arranged below the truck platform; the top of the column is sleeved with a rotating arm used for rotating relative to the column, and a pulley is respectively arranged at the top end of the column and one end of the rotating arm away from the column; a steel wire rope in the hoisting machine passes through the inside of the column and the rotating arm, and then passes through the pulley at the top end of the column, the pulley at one end of the rotating arm away from the column and a lift hook, and is fixedly connected with the rotating arm finally. The hoisting mechanism of the asphalt pavement maintenance truck is simple in structure and small in occupied space, and is suitable for the asphalt pavement maintenance truck to hoist heavy objects; meanwhile, the hoisting mechanism of the asphalt pavement maintenance truck is additionally provided with a positioning pin for preventing rotation and an a positioning ring for preventing swing, so that no effect is generated during vehicle-carried movement.
Description
Technical field
The utility model relates to a kind of hoisting mechanism of asphalt pavement maintanance truck.
Background technology
At present, asphalt pavement maintanance truck, when carrying out operation, may need to carry out weight carrying, if call Other Engineering machinery, carries out less important work, has not only reduced work efficiency, has also increased construction cost simultaneously; If adopt the mode of a dead lift, overweight object still cannot be processed effectively.
Summary of the invention
The utility model provides a kind of hoisting mechanism of asphalt pavement maintanance truck, has mainly solved the problem that existing asphalt pavement maintanance truck cannot carry out weight carrying.
Concrete technical solution of the present utility model is as follows:
The hoisting mechanism of this asphalt pavement maintanance truck, comprises the column being fixedly installed in vehicle platform, and vehicle platform below is provided with the winch for promoting; Described column top is socketed with the pivot arm for being rotated with respect to column, and column top and pivot arm are provided with pulley away from column one end; Steel rope on described winch pulley, suspension hook away from column one end through the pulley on column top, pivot arm again behind column and pivot arm inside, is finally fixedly connected with in pivot arm.
Above-mentioned column is fixed in vehicle platform by bearing, is provided with the steady ring for preventing that hook from swinging on bearing.
The outside of above-mentioned column outside, pivot arm and column socket place is provided with suitable snap ring, and snap ring prevents that for plug-in mounting pivot arm is with respect to the fastening screw of column rotation.
Above-mentioned column and pivot arm socket are specifically, described column top arranges three grades of steps, pivot arm and column socket part are provided with and these three grades of steps that step is suitable, between the first order step of column and pivot arm step, be provided with plain bearing, between the third stage step of column and pivot arm step, be provided with plain bearing and antifriction-bearing box.
The utility model has the advantage of:
The hoisting mechanism of this asphalt pavement maintanance truck is simple in structure, it is little to take up room, and is applicable to the lifting that asphalt pavement maintanance truck carries out weight; Meanwhile, the hoisting mechanism of this asphalt pavement maintanance truck has been set up the steady ring that prevents rotating fastening screw and prevent from swinging, and during vehicular motion, can not produce any impact.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Accompanying drawing is detailed as follows: 1-column; 2-pivot arm; 3-fastening screw; 4-pulley; 5-suspension hook; 6-steel wire; 7-steady ring; 8-winch; 9-vehicle platform; 10-plain bearing; 11-antifriction-bearing box.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail, as shown in Figure 1:
The hoisting mechanism of this asphalt pavement maintanance truck, comprises the column being fixedly installed in vehicle platform, and vehicle platform below is provided with the winch for promoting; Described column top is socketed with the pivot arm for being rotated with respect to column, column top arranges three grades of steps, pivot arm and column socket part are provided with and these three grades of steps that step is suitable, between the first order step of column and pivot arm step, be provided with plain bearing, between the third stage step of column and pivot arm step, be provided with plain bearing and antifriction-bearing box, socket between column and pivot arm can adopt multitude of different ways, and such scheme is only embodiment, so that reference to be provided.
Pivot arm bottom and be provided with pulley away from column one end; Steel rope on described winch behind column and pivot arm inside again through pivot arm bottom away from pulley, the suspension hook of column one end, finally in pivot arm, be fixedly connected with; By bearing, be fixed in vehicle platform, on bearing, be provided with the steady ring for preventing that hook from swinging; The outside of column outside, pivot arm and column socket place is provided with suitable snap ring, and snap ring prevents that for plug-in mounting pivot arm is with respect to the fastening screw of column rotation.
During use, extract fastening screw, pivot arm can be rotated with respect to column,, hook is deviate from from steady ring meanwhile, can carry out lifting operation; By the vertical lift of hoisting object, by winch, pulled steel rope to realize, horizontally rotate by manpower and rotate realization.
