Cable anti-dragging device

Technical Field

The utility model relates to a cable anti-dragging device.

Background

The drill jumbo is a trackless rock drilling device which adopts the drilling and blasting method to construct in underground mining engineering, and can be matched with a shovel loading device to accelerate the construction speed, improve the labor productivity and improve the labor condition. The main power of the drill jumbo is derived from a three-phase alternating current motor with 380V vehicle rated voltage and 55KW power, and the motor power supply is externally connected to a stope distribution box through a vehicle-mounted cable, so that the movement of the drill jumbo can drag the cable to generate larger pulling force in use.

Because at present, a cable anti-dragging device is lacking, the problem that the cable is dragged by the drilling jumbo is difficult to solve, under extreme conditions, the cable is caused to drag the distribution box to disconnect a cable connector from a circuit breaker, and when serious, the cable connector and the circuit breaker are damaged, so that great potential safety hazards exist and the construction efficiency is influenced to a certain extent.

The utility model has the positive effects that:

the utility model has the advantages of simple structure and convenient installation and operation, and when in use, the dragging tension generated by equipment movement is transferred from the cable to the netting, the netting has better tightening effect for the net structure, the stress area is large, the stress can be effectively dispersed, the disconnection fault of the cable and the circuit breaker caused by overlarge tension in the cable dragging process is avoided, the stable operation is ensured, and the potential safety hazard is eliminated.

The second, the utility model, the connecting rope and the hanging ring are integrally knitted, no junction point exists, the connection is realized by pressing the pressing sleeve, the stress transmission is uniform, the possibility of local fracture caused by uneven stress is reduced, and the reliability of the cable anti-dragging device is further improved.

Thirdly, the lower end of the utility model is fixed by adopting the limiter, the outline dimension of the limiter is larger than the wire winding opening of the cable guide, and the cable can be prevented from being excessively wound into the roller when the cable is wound after the operation is finished, so that the operation steps of field workers are simplified, and the labor cost is saved.

Drawings

Fig. 1 is a schematic structural diagram of an embodiment of the present utility model.

Fig. 2 is an enlarged view of the stopper in the embodiment of the present utility model.

In the figure: 1. the cable fixing device comprises a limiter, a braiding net, a positioning ring, a connecting rope, a pressing sleeve, a lifting ring, a cable, a fixing sleeve I, a fixing sleeve II, a fixing bolt 1-3 and a fixing pad 1-4.

Detailed Description

The utility model is further described below with reference to the drawings and examples.

As in fig. 1, an embodiment of the utility model comprises a netting 2 for sheathing the outside of a cable 7. The mesh 2 is cylindrical and made of a metal material such as galvanized or stainless steel wire. One end of the netting 2 is connected with a limiter 1 for fixing the netting 2 on the outer side of a cable 7, and the other end of the netting 2 is connected with a hanging ring 6 through a connecting rope 4.

Further, the netting 2, the connecting rope 4 and the hanging ring 6 are integrally knitted. The connecting rope 4 is wrapped with a pressing sleeve 5. The pressing sleeve 5 is made of metal material (such as aluminum), and the pressing sleeve 5 tightens part of the netting 2 into the connecting rope 4 through pressing and wrapping.

Further, the embodiment also comprises a positioning ring 3 arranged at the joint of the netting 2 and the connecting rope 4. The retaining ring 3 is of a rigid material (e.g. metal) and has an inner diameter greater than the outer diameter of the cable 7. The function of the positioning ring 3 is to support the mesh of the netting 2 so as to facilitate the penetration of the cable 7 into the netting 2.

As shown in fig. 2, the limiter 1 is formed by fastening a first fixing sleeve 1-1 and a second fixing sleeve 1-2, wherein semicircular grooves are formed in the centers of the first fixing sleeve and the second fixing sleeve respectively, through fixing bolts 1-3.

Further, the semicircular groove is internally provided with a fixed pad 1-4. The fixing pad 1-4 is made of soft material (such as rubber).

The following is an example of the procedure used in the embodiments of the present utility model.

In use, one end of the limiter 1 faces the electric equipment, and one end of the hanging ring 5 faces the cable guide or the power supply.

Hanging ring 6 to the cable hook on the side of the power supply, penetrating cable 7 from positioning ring 3, penetrating through the middle of tubular net 2, detaching fixing bolt 1-3, and connecting electric equipment after penetrating out from limiter 1.

The cable 7 is arranged between the fixing pads 1-4, and the fixing bolts 1-3 are screwed down, so that the first fixing sleeve 1-1 and the second fixing sleeve 1-2 are fastened on the cable 7.

After the installation, when the device moves to drag the cable 7 to generate a pulling force, the limiter 1 moves along the cable 7 in the pulling force direction because the limiter 1 is fixed on the cable 7. The movement of the limiter 1 can also enable one end of the connected netting 2 to follow the movement of the netting, and since the other end of the netting 2 is connected with the hanging ring 6 and the hanging ring 6 is hung at the cable hook, the tension starts from the limiter 1, and is transmitted to the cable hook along with the deformation of the netting 2 through the connecting rope 4 and the hanging ring 6, so that the whole cable anti-dragging device can tend to be in a tight state. That is, the pulling force of the device moving the drag cable 7 is transmitted to the cable hooking place without the cable 7 being affected by the pulling force.

After the operation is finished, the cable 7 is received by using the cable guide, and the limiter 1 can prevent the cable 7 from continuously entering the cable guide because the diameter of the limiter 1 is larger than the diameter of a winding opening of the cable guide, so that the cable is prevented from being wound into the roller excessively, the operation steps of field workers are simplified, and the labor cost is saved.
