Abstract
The utility model belongs to the technical field of coal mine underground fully mechanized mining, fully mechanized coal caving coal face and specifically relates to a fixing device is connected to removable coal-winning machine cable clamp. The cable groove is mainly formed by welding a connecting plate, a fixing plate and a guide pipe and is installed at the cable groove of the scraper conveyor through bolts. The connecting and fixing device for the cable clamp of the coal mining machine can prevent safety accidents caused by cable damage due to the fact that a cable rubs between the cable groove leading-in port and the cable groove when the coal mining machine moves to drag the cable, and can be used for connecting and fixing the whole cable after being laid with the cable clamp without penetrating the cable from one end. The utility model discloses simple structure, simple to operate saves time, reduces intensity of labour, improves work efficiency.
Description
Technical Field
The utility model belongs to the technical field of coal mine underground fully mechanized mining, fully mechanized coal caving coal face and specifically relates to a fixing device is connected to removable coal-winning machine cable clamp.
Background
The problem of fixing a cable clamp of a coal mining machine on a coal mine underground working face is a technical problem in the coal mining industry all the time. Generally, after the cable is installed on the cable clamp of the coal mining machine, the cable clamp is freely placed in a cable groove of a scraper machine, and when the coal mining machine goes upwards (or downwards) for coal mining and turns back, the coal mining machine can generate a cable stacking phenomenon in the process of dragging the cable. Especially, at the position where the cable is led out from the cable groove to the cable clamp, the cable clamp is not fixed, so that the coal mining machine can drive the cable clamp to move when dragging the cable, the cable is abraded at the position, and even a safety accident that the cable is broken due to blocking is possibly caused. Therefore, a safe and reliable detachable coal mining machine cable clamp connecting and fixing device is needed to be provided, so that the safety of the underground coal mining working surface can be ensured, and the requirement of automatic mining development can be met.
Disclosure of Invention
An object of the utility model is to provide a fixing device is connected to removable coal-winning machine cable clamp, makes it can fix the coal-winning machine cable clamp, prevents the unable protection cable of cable clamp drunkenness to guarantee the safety high efficiency of coal seam exploitation in the pit.
The utility model adopts the technical proposal that: a detachable coal cutter cable clamp connecting and fixing device comprises a cable clamp, a connector, a bolt and a cable groove;
the connector comprises a connecting plate, a fixing plate, a guide pipe, a U-shaped plate and a connecting plate, and is formed by welding, and threaded holes are processed on the fixing plate and the guide plate;
further fixing the cable clamp, the connector and the cable groove by bolts;
the cable clamp (1) can further rotate around the hinge point of the connector (2) within 30 degrees in the clockwise direction;
the utility model has the advantages that: the detachable coal mining machine cable clamp connecting and fixing device is simple in structure, low in cost, convenient to install, capable of being disassembled and assembled at any time, and free of considering the cable laying sequence. The cable has good protection at the leading-out position of the cable groove, reduces abrasion, avoids accidents caused by cable breakage, improves the safety of coal mine production, and meets the requirements of high-yield and high-efficiency mining of a coal mine underground working face.
In the following, the technical solutions in the embodiments of the present invention are described completely and clearly with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, but not all embodiments.
Description of the drawings:
fig. 1 is a schematic top view of the connector of the present invention;
FIG. 2 is a front view of the assembly of the connecting and fixing device of the present invention;
FIG. 3 is a schematic top view of the assembly of the connecting and fixing device of the present invention;
wherein: 1 cable clamp, 2 connectors, 3 bolts, 4 cable grooves, 21 connecting plates, 22 fixing plates, 23 guide pipes, 24 guide plates, 25L-shaped plates, 41 backing plates, 42 baffle plates and 5 cables.
The specific implementation mode is as follows:
as shown in fig. 1, the connector 2 is formed by welding a connecting plate 21, a fixing plate 22, a guide tube 23, a guide plate 24 and an L-shaped plate 25, and a section of the guide tube 23 is welded inside to prevent the cable from being scratched by the edge of the guide plate 24. The clearance L5 between the guide plate 24 and the L-shaped plate 25 is 3-4 mm larger than the thickness of the backing plate (41) in the cable trough (4);
as can be seen from fig. 2 and 3, the cable clamp 1 is of a closed structure in a shape like a Chinese character 'hui' after being assembled, the cable clamps 1 are connected end to end through bolts and nuts, a cable 5 is laid in the closed cable clamp 1, the connector 2 and the cable trough 4 are hinged together through the bolts 3, and the cable clamp 1 can rotate around the connector 2 in a clockwise direction within 30 degrees through the bolts 3 so as to meet the requirement of bending of the cable when a coal mining machine is used for mining coal;
as shown in fig. 3, the connector 4 and the pad plate 41 are fixed by the bolts 3 to form a rigid structure, the baffle 42 can prevent the cable clamp from sliding off the cable groove, the effective width L1 of the cable groove 4 is 5-10 mm larger than the total width L2 of the connector 4, and the width L4 of the cable clamp 1 is larger than L3 and smaller than L2.
In conclusion, the detachable coal cutter cable clamp connecting and fixing device is of an integral structure, when the coal cutter is used for mining coal, only the cable clamp moves along with the coal cutter, and the cable is still relative to the cable clamp all the time, so that the cable is protected and guided from the leading-out position of the cable groove, and the underground safe and efficient production is guaranteed.
It should be understood that the above detailed description of the technical solution of the present invention with the help of preferred embodiments is illustrative and not restrictive. After reading the description of the present invention, those skilled in the art may modify the technical solutions described in the embodiments or make equivalent substitutions for some technical features, and these modifications or substitutions do not make the essence of the corresponding technical solutions depart from the spirit and scope of the technical solutions of the embodiments of the present invention.
