Abstract

The utility model belongs to the technical field of traction equipment of cable equipment manufacturers, and especially discloses a tractor. The tractor comprises a tractor rack, the front side of the tractor rack is equipped with a driving shaft and a driven shaft, the driving shaft is equipped with a driving wheel while the driven shaft is equipped with a driven wheel, the middle part of the tractor rack is equipped with a drive motor, the motor shaft of the drive motor is connected with a worm gear reducer, and the driving shaft is driven by the worm gear reducer. The tractor provided by the utility model can realize traction of wires and cables through simple operation, is low in labor intensity, can structurally adapt to wires and cables of various specifications, causes no damages to the tracted wires and cables, and is low in required dynamic power and simple in structure; and the driving wheel and the driven wheel of the tractor can be replaced as required, bringing convenience of installation by customers.

Description

Hauling machine

Technical field

The utility model belongs to cable apparatus manufacture owner's pulling equipment technical field, refers in particular to a kind of hauling machine.

Background technology

At present, along with various industries are increasing to the demand of communication technology, diameter and the weight of cable increase gradually, in construction and repair procedures, carry cable and become very heavy work, especially in factory, in the repair work of the electric wire that mine uses, because there is no professional equipment, while needing carefully check and repair for every wire cable, its workload is very large, need to pull electric wire bundled or in heaps, cable repair work becomes heavy muscle power work, repairman's requirement itself is increased, and operating efficiency is very low.

Summary of the invention

The purpose of this utility model is to provide a kind of hauling machine simple in structure, safe and reliable.

The purpose of this utility model is achieved in that

Hauling machine, comprise traction frame, the installed in front of traction frame has driving shaft and driven axle, driving wheel is installed on driving shaft, follower is installed on driven axle, the middle part of traction frame is provided with drive motors, and the motor shaft of drive motors is connected with worm type of reduction gearing, and worm type of reduction gearing drives described driving shaft.

Preferably, on described driven axle, follower being installed is: driven axle is fixedly mounted in traction frame, the front end of driven axle is provided with two radial ball bearings, between two radial ball bearings, is provided with bearing spacer, and the outer ring body of described radial ball bearing is inlaid in the mesopore of described follower.

Preferably, the output shaft of described worm type of reduction gearing and described driving shaft are integral type structure.

Preferably, the diameter of described driving wheel is greater than the diameter of follower.

Preferably, described drive motors is three-phase brake motor.

The utility model compared to existing technology outstanding and useful technique effect is:

The utility model can be realized traction electric wire by shirtsleeve operation, and labour intensity is low, and this haulage gear can adapt to the electric wire of all size, can not cause damage to drawn electric wire, and demand motive force power is low, simple in structure; Driving wheel of the present utility model and follower can be exchanged as required, facilitate client's arrangement.

Embodiment

The utility model is further described with specific embodiment below in conjunction with accompanying drawing, referring to Fig. 1-3:

Hauling machine, comprise traction frame 1, the installed in front of traction frame 1 has driving shaft 2 and driven axle 3, driving wheel 4 is installed on driving shaft 2, follower 5 is installed on driven axle 3, the middle part of traction frame 1 is provided with drive motors 12, and the motor shaft of drive motors 12 is connected with worm type of reduction gearing 11, and worm type of reduction gearing 11 drives described driving shaft 2.

Preferably; on described driven axle 3, follower 5 being installed is: driven axle 3 is fixedly mounted in traction frame 1; the front end of driven axle 3 is provided with two radial ball bearings 13; between two radial ball bearings 13, be provided with bearing spacer 10; the outer ring body of described radial ball bearing 13 is inlaid in the mesopore of described follower 5; this design makes follower have the function of automatic adaptation cable tensile force, has avoided the phenomenon that cable skids at follower to occur, and has protected the useful life of cable and equipment.

Preferably, the output shaft of described worm type of reduction gearing 11 and described driving shaft 2 are integral type structure.

Preferably, the diameter of described driving wheel 4 is greater than the diameter of follower 5.

Preferably, described drive motors 12 is three-phase brake motor.

Above-described embodiment is only preferred embodiment of the present utility model, not limits according to this protection range of the present utility model, therefore: all equivalences of doing according to structure of the present utility model, shape, principle change, within all should being covered by protection range of the present utility model.
