Technical Field

[0001] The present utility model relates to the technical field of coal mine electromechanical equipment, specifically to a novel power cable retracting and releasing device for continuous miners. Background Art

[0002] In underground coal mines, the roadway tunneling process using a continuous miner is a roadway mechanical tunneling process with relatively high tunneling efficiency; the main supporting equipment for the continuous miner includes a shuttle car, a crusher and a large bolter miner; the crusher is a relatively fixed device and is lapped with the tail of the crossheading belt conveyor; the continuous miner, the shuttle car and the large bolter miner are mobile devices, and the approximately 80-meter power cable moves along with the equipment. At present, there is a lack of corresponding power cable retracting and releasing devices, so the power cable is directly dragged on the roadway ground, which may cause the power cable to be rolled over or even damaged, thus affecting the working efficiency of the continuous miner.

[0003] In view of this, a novel power cable retracting and releasing device for continuous miners is proposed. Contents of the Utility Model

[0004] The present utility model aims to provide a novel power cable retracting and releasing device for continuous miners.

[0005] To achieve the above purpose, the present utility model provides the following technical solutions: A novel power cable retracting and releasing device for continuous miners, comprising: a retracting and releasing assembly, which comprises a fixing seat fixed on the inner top of the roadway by anchor rods, two connecting strips symmetrically fixed at the bottom of the fixing seat, a first roller movably installed between the two connecting strips, a concave seat installed on the roadway ground, a second roller movably installed inside the concave seat, and a power cable body wound outside the second roller and lapped outside the first roller.

[0006] Preferably, the second roller is driven by a motor installed on the outer wall of the concave seat.

[0007] Preferably, a limit strip is arranged between the two connecting strips, two bearing plates are symmetrically fixed at the top of the limit strip, and the two bearing plates are respectively connected with the two connecting strips correspondingly by two fixing bolts.

[0008] Preferably, the device further comprises a protection assembly, and the protection assembly comprises a connecting ring fixed on the outer wall of the concave seat, a protective cover abutting against one end of the connecting ring, and a fixing ring arranged outside the connecting ring and the protective cover.

[0009] Preferably, the outer walls of the connecting ring and the protective cover are respectively provided with a first external thread and a second external thread, the inner wall of the fixing ring is provided with an internal thread, and the fixing ring is in threaded connection with the abutting position of the connecting ring and the protective cover by matching the internal thread with the first external thread and the second external thread.

[0010] Preferably, it further includes a positioning component, which includes a movable groove formed on the outer wall of the concave seat, a movable block movably installed inside the movable groove, a rotating disk fixed to one end of the movable block, a limiting ear fixed to the outer wall of the rotating disk and abutting against the end of the fixing ring, a collar fixed to the outer wall of the rotating disk, a movable hole formed at the end of the collar, a locking hole formed on the outer wall of the concave seat, a fixing rod movably disposed in the movable hole, and a receiving ring fixed to the outer wall of the fixing rod.

Detailed Implementation

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods. Example

[0018] Please see Figure 1-4This utility model provides a technical solution: To achieve the above objectives, this utility model provides the following technical solution: A novel power cable winding and unwinding device for a continuous mining machine, comprising: a winding and unwinding assembly 100, including a fixed base 101 fixed to the top of the roadway by anchor bolts 102, two connecting strips 103 symmetrically fixed to the bottom of the fixed base 101, a first roller 104 movably installed between the two connecting strips 103, a concave base 105 installed on the roadway floor, a second roller 106 movably installed inside the concave base 105, and a power cable body 107 wound around the outside of the second roller 106 and overlapping the outside of the first roller 104. The second roller 106 is driven by a motor 108 installed on the outer wall of the concave base 105, and a winding and unwinding device is provided between the two connecting strips 103. A limiting strip 109 is provided, and two receiving plates 110 are symmetrically fixed to the top of the limiting strip 109. The two receiving plates 110 are respectively connected to the two connecting strips 103 by two fixing bolts 111. The protective component 200 is also included. The protective component 200 includes a connecting ring 201 fixed to the outer wall of the concave seat 105, a protective cover 202 abutting against one end of the connecting ring 201, and a fixing ring 203 disposed outside the connecting ring 201 and the protective cover 202. The outer walls of the connecting ring 201 and the protective cover 202 are respectively provided with a first external thread and a second external thread. The inner wall of the fixing ring 203 is provided with an internal thread. The fixing ring 203 is threadedly connected to the abutting point of the connecting ring 201 and the protective cover 202 by the internal thread and the first and second external threads.

[0019] Specifically, since the power cable body 107 is wound around the outside of the second roller 106, the second roller 106 can be rotated forward and backward by the motor 108, which enables the power cable body 107 to be wound up and down. The power cable body 107 is attached to the outside of the first roller 104, which is suspended from the top of the roadway by the anchor rod 102, the fixing seat 101, and the two connecting strips 103. This avoids the power cable body 107 from being crushed and damaged. Compared with the existing technology, this utility model can freely wound up and down the power cable body 107, which can avoid crushing and damage to the power cable body 107 without affecting the working efficiency of the continuous mining machine, thus effectively ensuring the working efficiency of the continuous mining machine.

[0020] Two fixing bolts 111 are used in conjunction with two receiving plates 110 to fix the limiting strip 109 between the two connecting strips 103. The limiting strip 109 can limit the power cable body 107, prevent the power cable body 107 from shifting outside the first roller 104, and ensure the winding and unwinding efficiency of the power cable body 107.

[0021] The protective cover 202 is abutted against the connecting ring 201, and then the fixing ring 203 is threaded to the abutment of the connecting ring 201 and the protective cover 202 by using the internal thread and the first external thread and the second external thread. The protective cover 202 can be fixed. Since the protective cover 202 is set outside the motor 108, the protective cover 202 can prevent the dust in the roadway from affecting the motor 108, thereby improving the working efficiency and service life of the motor 108. Example

[0022] Please see Figure 1 , 3 -5. This utility model provides a technical solution: a novel power cable retraction and deployment device for a continuous mining machine, further comprising a positioning component 300. The positioning component 300 includes a movable groove 301 formed on the outer wall of a concave seat 105, a movable block 302 movably installed inside the movable groove 301, a rotating disk 303 fixed to one end of the movable block 302, a limiting ear 304 fixed to the outer wall of the rotating disk 303 and abutting against the end of a fixing ring 203, and a collar 3 fixed to the outer wall of the rotating disk 303. 07. A movable hole 308 is opened at the end of the collar 307, a locking hole 306 is opened on the outer wall of the concave seat 105, a fixing rod 309 is movably set in the movable hole 308, and a receiving ring 311 is fixed on the outer wall of the fixing rod 309. A pull plate 310 is fixed at one end of the fixing rod 309, and the other end of the fixing rod 309 is engaged in the locking hole 306. A spring 305 is provided on the outside of the fixing rod 309, and the two ends of the spring 305 are respectively fixed to the receiving ring 311 and the collar 307.

[0023] Specifically, the rotating disk 303 can be driven to rotate by the cooperation of the movable groove 301 and the movable block 302. When the limiting ear 304 abuts against the end of the fixed ring 203, the fixed rod 309 will be driven to move in the movable hole 308 of the connecting ring 201 under the action of the spring 305. When the fixed rod 309 is engaged in the slot 306, the limiting ear 304 can be fixed. The limiting ear 304 can prevent the fixed ring 203 from loosening or falling off, thereby ensuring the stability of the protective cover 202 and improving the protective effect of the protective cover 202 on the motor 108.

[0024] Working principle: First, the anchor bolt 102 is used to fix the fixing seat 101 to the inner top of the roadway. Then, the concave seat 105 is placed on the roadway floor. One end of the power cable body 107 is inserted into the outside of the first roller 104, and both ends of the power cable are connected to the continuous mining machine and the power equipment, respectively. When the continuous mining machine is working and moving, the motor 108 is started appropriately. The motor 108 drives the second roller 106 to rotate forward and backward, which can realize the winding and unwinding of the power cable body 107. The power cable body 107 is attached to the outside of the first roller 104. The first roller 104 is suspended from the inner top of the tunnel using anchor bolts 102, fixing seats 101, and two connecting strips 103. This prevents the power cable body 107 from being crushed and damaged. Furthermore, two fixing bolts 111, in conjunction with two receiving plates 110, fix the limiting strip 109 between the two connecting strips 103. The limiting strip 109 can limit the movement of the power cable body 107, preventing it from shifting outside the first roller 104 and ensuring the safety of the power cable body 107. To improve the efficiency of the motor 108, the protective cover 202 is brought into contact with the connecting ring 201. Then, using the internal thread and the first and second external threads, the fixing ring 203 is threaded to the contact point between the connecting ring 201 and the protective cover 202, thus fixing the protective cover 202. Since the protective cover 202 is located outside the motor 108, it prevents dust in the tunnel from affecting the motor 108, thereby improving the working efficiency and service life of the motor 108. (The last sentence appears to be incomplete and possibly refers to a different topic.) With the cooperation of 02, the rotating disk 303 can be driven to rotate. When the limiting ear 304 abuts against the end of the fixing ring 203, the fixing rod 309 will be driven to move in the movable hole 308 of the connecting ring 201 under the action of the spring 305. When the fixing rod 309 is engaged in the locking hole 306, the limiting ear 304 can be fixed. The limiting ear 304 can prevent the fixing ring 203 from loosening or falling off, thereby ensuring the stability of the protective cover 202 and improving the protective effect of the protective cover 202 on the motor 108.
