Description

Coal machine cable frame heightening device

Technical Field

The utility model belongs to the technical field of coal mining, concretely relates to coal machine cable frame heightening device.

Background

The coal machine drag chain back department often can be surplus a part drag chain, very easily drops after folding, finally leads to the cable to damage, influences the normal production of working face, if change, not only cable cost is high but also the process is complicated, brings very big puzzlement for the raw coal production work of working face.

And some current coal machines drag cable set up the cable duct on the cargo airplane, put into the cable duct with the cable, but the cable duct crosses lowly and leads to the cable conductor to hang the cable excessively to lead to dragging the cable, and then take place the cable and break and split.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a coal machine cable frame heightening device has solved the transportation machine cable inslot portion cable conductor that exists among the prior art and has crossed low and cause the dragging cable phenomenon to take place to lead to the cable to break and cracked problem.

The utility model discloses the technical scheme who adopts is, coal machine cable frame heightening device, include a plurality of connecting rods with the horizontal end to end fixed mounting of cargo airplane protection frame, the connecting rod deviates from the clamp that one side fixed mounting that the protection frame was installed is used for fixed cable, is provided with buckle device on the clamp, and the cable passes the clamp and is fixed by buckle device.

The utility model discloses a characteristics still lie in:

the connecting rod welding has the boss, and the boss deviates from the one end fixed mounting clamp of face of weld.

The buckle device comprises a first clamp and a second clamp ring, one end of the extending end of the clamp is wrapped on one end of the first clamp ring and one end of the second clamp ring, and the other end of the extending end of the clamp penetrates through the first clamp ring and extends out of the other end of the second clamp ring through folding.

At least two clamps are provided.

The clamp is three.

The utility model has the advantages that:

the coal machine drags cable return department often can be surplus some and drags the cable, very easily drops after folding, finally leads to the cable to damage, influences the normal production of working face, if change, not only cable cost is high but also the process is complicated, brings very big puzzlement for the raw coal production work of working face.

By carefully considering the practical situation of the structure of the coal mining machine on the fully mechanized mining face, the cable frame heightening device for the coal processing machine is consistently and favorably commented by field use, and the damage of a trailing cable can be effectively avoided.

The cable lifting device is arranged on the protective frame of the conveyor instead of the cable groove of the conveyor, so that the problem that the ground cable is broken and broken due to the fact that the phenomenon of lifting the cable is caused by the fact that the cable in the cable groove of the conveyor is too low can be effectively solved.

Drawings

FIG. 1 is a schematic structural view of a coal machine cable rack heightening device of the present invention;

FIG. 2 is an enlarged view of a portion of FIG. 1;

FIG. 3 is a mounting effect diagram of a coal machine cable rack heightening device.

The protection device comprises a connecting rod 1, a hoop 2, a buckle device 3, a first clamping ring 3-1, a second clamping ring 3-2, a boss 4 and a conveyor protection frame 5.

Detailed Description

The present invention will be described in detail with reference to the accompanying drawings and specific embodiments.

Coal machine cable frame heightening device, as shown in figure 1 or 3, include with a plurality of connecting rods 1 of the horizontal end to end fixed mounting of conveyer protection frame, connecting rod 1 deviates from one side fixed mounting in the protection frame installation and is used for fixing cable's clamp 2, is provided with buckle device 3 on clamp 2, and the cable passes clamp 2 and is fixed by buckle device 3. The number of the hoops 2 is three.

The connecting rod 1 and the conveyor protection frame 5 are preferably welded, the welding mode is firm and stable, and the service life of the connecting rod is ensured; the material of clamp 2 can be strap or reflection of light area, and its plastic deformation and elastic deformation are good, guarantee to laminate the cable well, and set up three clamp (1 each at connecting rod 1 both ends, middle 1), can be fixed firm with the cable, guarantee can not break away from connecting rod 1.

Connecting rod 1 welding has boss 4, and boss 4 deviates from the one end fixed mounting clamp 2 of face of weld.

The boss 4 ensures that the connecting rod 1 is connected with the clamp 2, so that the connection is firm and sufficient movement allowance is ensured.

As shown in fig. 2, the fastening device 3 includes a first snap ring 3-1 and a second snap ring 3-2, one end of the extending end of the clip 2 wraps one end of the first snap ring 3-1 and one end of the second snap ring 3-2, and the other end of the extending end of the clip 2 passes through the other end of the first snap ring 3-1 and is folded to extend out from the other end of the second snap ring 3-2.

The form of application snap ring, then can realize locking the cable or loosening the cable through the tip of artificially pulling clamp 2, its specific operation process as follows:

the cable is placed on clamp 2, with clamp 2 through 3 artificial downwardly pulling clamps 2 of buckle device, then clamp 2 contracts, causes the cable to be locked, and the end of reverse unclamping clamp 2 then the cable is loosened.

The utility model discloses coal machine cable frame heightening device can effectively solve conveyer cable inslot portion cable conductor and cross lowly and cause to pull the cable phenomenon and take place to lead to the ground cable to break and cracked problem.
