Description

Technical Field

[0001] The utility model belongs to the technical field of coal mining, and in particular relates to a cable hanging device for electromechanical transportation in coal mines. Background Art

[0002] With the acceleration of the automated production process of coal mining enterprises, a large number of mechanical equipment are needed in the mining process of underground coal mines, and these mechanical equipment need to be powered by cables of various models and specifications when starting and controlling them.

[0003] At present, for cables used to connect various mechanical equipment such as coal mining machine cables at the coal mining face in underground coal mine tunnels, they need to move with the continuous advancement of the coal mining face and the movement of equipment such as comprehensive mining machines. In order to avoid being scratched by sharp objects on the ground during movement when the cables are directly laid on the ground, they are generally hung on the coal wall of the tunnel using a hanging device.

[0004] However, due to the relatively simple and fixed structure of the existing hanging device and the complex conditions in the coal mine, the existing hanging device will have the following problems during actual use and installation: it is easy for it to be unable to be installed on the coal wall of the tunnel due to its inability to freely change the installation posture; as a result, the cable is prone to drooping during the laying process due to too few or missing hanging points. In severe cases, it may even cause surface scratches and hanging damage to the cable during movement. Utility Model Content

[0005] The technical problem solved by the utility model is to provide a cable hanging device for electromechanical transportation in coal mines which can flexibly adjust its own posture, and can adjust its own posture according to the actual installation situation in the tunnel to adapt to various installation and use environments.

[0006] In order to solve the above technical problems, the technical solution provided by the utility model is: a cable hanging device for electromechanical transportation in coal mines, which includes a fixing plate and a cable fixing assembly, the fixing plate is provided with an installation through hole, and a first extension plate and a second extension plate are fixedly provided on one side of the fixing plate in sequence from top to bottom, and a first adjustment plate is rotatably installed on the end of the first extension plate, and at least two slots are provided on the side of the first adjustment plate facing the fixed plate; a push rod is hinged on the end of the second extension plate, and the end of the push rod is plugged into the corresponding slot on the first adjustment plate; an adapter plate is provided at the lower end of the cable fixing assembly, and a second adjusting plate is rotatably installed on the end of the adapter plate, and an end of the second adjusting plate away from the adapter plate is rotatably installed together with an end of the first adjusting plate away from the fixed plate, and a fixing block is respectively provided on the side of the second adjusting plate facing the fixed plate and the side of the first adjusting plate away from the fixed plate, and an adjustable support rod is connected between the two fixing blocks. In this way, since any two adjacent components among the first extension plate, the first adjustment plate, the second adjustment plate, and the adapter plate in the utility model can rotate relative to each other, the utility model can flexibly adjust the relative position between the fixing plate and the cable fixing assembly, that is, adjust its own posture, so that it can adjust its own posture according to the actual installation situation in the lane to adapt to a variety of installation and use environments.

[0007] Furthermore, the adjustable strut includes a threaded tube, each of the two ends of the threaded tube is threadedly connected to a second threaded column, the two second threaded columns are arranged with opposite rotation directions, and a connecting plate is arranged on the end of the two second threaded columns away from the threaded tube, and the connecting plate is hinged on the corresponding fixed block through a pin shaft. At this time, the length of the entire adjustable strut can be adjusted by screwing the threaded tube to adapt to the angle between the first adjustment plate and the second adjustment plate.

[0008] Furthermore, hinge holes are provided at the ends of the first extension plate and the two ends of the first adjustment plate, the two ends of the second adjustment plate, and the lower end of the adapter plate. The ends of the bolts are threadedly connected with the first nuts after passing through the corresponding two hinge holes, so as to realize the rotatable installation between the first extension plate and the first adjustment plate, between the first adjustment plate and the second adjustment plate, and between the second adjustment plate and the adapter plate. When it is necessary to adjust the angle between the first extension plate and the first adjustment plate, the nut on the bolt at this position can be loosened first, so that the first adjustment plate can swing freely relative to the first extension plate, and then the angle of the first adjustment plate can be swung, and when the angle is appropriate, the nut on the bolt at this position can be tightened again until the first adjustment plate and the first extension plate cannot swing relative to each other, and the position adjustment of the first adjustment plate can be completed; similarly, it can also adjust the angle between the second adjustment plate and the first adjustment plate, and the angle between the second adjustment plate and the adapter plate.

[0009] Furthermore, the cable fixing assembly includes a base, a T-shaped slide groove is provided at the lower end of the base, a T-shaped slider is slidably installed in the T-shaped slide groove, and the lower end of the T-shaped slider is fixedly connected to the adapter plate; a lower pressing plate is installed at the upper end of the base, a lower fixing groove is provided at the upper end of the lower pressing plate, an upper pressing plate is provided above the lower pressing plate, and an upper fixing groove is provided at the lower end of the upper pressing plate, and the upper fixing groove is arranged one by one opposite to the lower fixing groove. In this way, since the base and the adapter plate in the utility model can slide relative to each other, the utility model can freely adjust the stretching angle of the cable through the relative movement between the base and the adapter plate, thereby avoiding scratches and damage to the cable.

[0010] Furthermore, at least two first threaded columns are installed at the upper end of the base, and a slide plate, a spring, and a second nut are sequentially sleeved on the first threaded column from bottom to top, the slide plate is fixedly connected to the edge of the upper pressure plate, and the second nut is threadedly connected to the first threaded column. In this way, the pressing force applied by the upper pressure plate to the cable in the utility model can be adjusted through the cooperation between the slide plate, the spring, the second nut and the first threaded column, thereby ensuring the pressing effect of the upper pressure plate and preventing the cable from slipping off.

[0011] Furthermore, both the upper fixing groove and the lower fixing groove are arc-shaped grooves to adapt to the shape of the cable.

[0012] It can be seen from the above technical scheme that the utility model has the following advantages: First, the utility model can flexibly adjust the relative position between the fixing plate and the cable fixing assembly, that is, adjust its own posture, so that it can adjust its own posture according to the actual installation situation in the tunnel to adapt to a variety of installation and use environments; secondly, the utility model can also freely adjust the stretching angle of the cable through the relative movement between the base and the adapter plate, thereby avoiding scratches and damage to the cable.
