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

[0028] In order to solve the problem in the prior art that laying and recycling cables increases the labor intensity of workers and poses safety hazards, the present application provides a cable winding and unwinding mechanism and a cable winding and unwinding vehicle for coal mines having the same.

[0029] like Figures 1 to 6 As shown, the cable winding and unwinding mechanism includes a chassis 10, a drum mechanism 20, a conveying mechanism 30 and a cable arrangement mechanism 40. The chassis 10 includes a chassis body 11 and a drum support portion 12, a first mounting portion 13 and a second mounting portion 14 arranged on the chassis body 11. The drum mechanism 20 is rotatably arranged on the drum support portion 12, and the drum mechanism 20 includes a drum 21, a first driving device 23, a first seat body 24, a bearing structure 22 and a second seat body 25. The first driving device 23 is arranged on the first seat body 24 and is drivingly connected to the first end of the drum 21 to drive the drum 21 to rotate; the bearing structure 22 supports the second end of the drum 21 and is arranged on the second seat body 25. The conveying mechanism 30 is arranged on the first mounting portion 13, and the conveying mechanism 30 includes a clamping portion 31, and the clamping portion 31 is used to clamp the cable, so as to drive the cable to rotate around the drum 21 through the clamping portion 31. The cable arrangement mechanism 40 is arranged on the second mounting portion 14, and is located between the drum mechanism 20 and the conveying mechanism 30; the cable arrangement mechanism 40 includes a movably arranged cable arrangement gantry 41, and the cable arrangement gantry 41 is used to pass the cable to drive the cable to reciprocate along a preset direction. Among them, the drum support portion 12 includes two supporting structures 121 arranged opposite to each other, the first seat body 24 is arranged on one supporting structure 121, and the second seat body 25 is arranged on the other supporting structure 121.

[0030] By applying the technical solution of this embodiment, the cable winding and unwinding mechanism realizes the mechanized operation of cable laying. Through the cooperation between the drum mechanism 20, the conveying mechanism 30 and the cable arrangement mechanism 40, the manual loading, unloading, pulling and laying of the cables are replaced, which greatly improves the cable laying efficiency, reduces the labor intensity of the staff, eliminates the potential safety hazards, and ensures the safety during the construction process, thereby solving the problem that the laying and recycling of cables in the prior art increases the labor intensity of the staff and poses a safety hazard. At the same time, the drum mechanism 20 is installed on the drum support part 12 through the first seat body 24 and the second seat body 25, that is, the drum mechanism 20 is connected to the drum support part 12 only by the two supporting parts of the first seat body 24 and the second seat body 25, thereby facilitating the workers to load and unload the drum mechanism, saving the time of loading and unloading the drum, and improving the efficiency of the cable winding and unwinding operation.

[0031] In this embodiment, the chassis 10 serves as a carrier of the entire mechanism, and its structure is a frame structure, which has the characteristics of strong structure and large load-bearing capacity, and can also adapt to the installation of explosion-proof rubber-wheeled vehicles.

[0032] like Figure 3 As shown, the first driving device 23 is a hydraulic motor, and the drum mechanism 20 also includes a first pressure detection device 26. The first pressure detection device 26 is used to detect the working pressure of the hydraulic motor, so as to obtain the tension borne by the cable wound on the drum 21 according to the detection value of the first pressure detection device 26; if the tension is greater than or equal to the preset tension value, the working pressure of the hydraulic motor is reduced. In this way, by real-time monitoring and controlling the working pressure of the hydraulic motor, it is possible to effectively prevent the cable from being damaged due to excessive tension during the winding and unwinding process, thereby ensuring the service life of the cable and the safety of the operation. At the same time, in the high-intensity operating environment of a coal mine, the above-mentioned setting can reduce the risk of cable wear and breakage, avoid production stagnation caused by cable failure, and thus improve the continuous operation capacity and economic benefits of the coal mine.

[0033] like Figure 3 and Figure 4As shown, the cable winding and releasing mechanism includes a control module, and the drum mechanism 20 includes a number of turns detection device 27. The control module is electrically connected to the first drive device 23 and the number of turns detection device 27. The number of turns detection device 27 includes a detection shaft 271 and a counter 272. The detection shaft 271 is connected to the drum 21 and rotates synchronously with the drum 21. The counter 272 is used to obtain the number of turns of the detection shaft 271. Among them, when the count value of the counter 272 reaches a preset number of turns, the first drive device 23 is controlled to stop running through the control module. In this way, the above-mentioned precise number of turns control avoids the disorderly winding and excessive winding of the cable, is particularly suitable for the automated management of coal mine cables, and improves the intelligence level of the equipment and the management efficiency of the cable. In practical applications, this intelligent control ensures the accuracy of cable winding and reduces the error of human operation, which plays an important role in improving the professional level of coal mine cable management and reducing the labor intensity of operators.

[0034] like Figure 3 As shown, the reel 21 includes a cylinder assembly 211, two second mounting plates 212 arranged opposite to each other, and a connecting shaft 213. The cylinder assembly 211 includes a cylinder 2111 and a first mounting plate 2112 arranged at both ends of the cylinder 2111. The two second mounting plates 212 arranged opposite to each other are arranged in the cylinder 2111. The connecting shaft 213 is arranged on one second mounting plate 212, and the connecting shaft 213 extends into the inner ring of the bearing structure 22 and is fixedly connected to the inner ring. Among them, the first driving device 23 is drivingly connected to the other second mounting plate 212. In this way, the above-mentioned arrangement ensures the stability and balance of the reel structure when rotating at high speed, and prolongs the service life. At the same time, the above-mentioned arrangement enables the reel mechanism 20 to achieve high-speed winding and unwinding under the premise of ensuring the safety of the cable, which not only improves the operating speed, but also reduces the equipment maintenance cost, and has a positive effect on the efficient operation of the coal mine.

[0035] In this embodiment, the cylinder 2111 can store a cable of φ100 mm and 500 m.

[0036] like Figure 6 As shown, the conveying mechanism 30 also includes a swing cylinder 32 and a connecting arm 33. One end of the connecting arm 33 is connected to the swing cylinder 32 so as to swing synchronously with the swing cylinder 32, and the clamping portion 31 is arranged on the other end of the connecting arm 33. In this way, when the conveying mechanism 30 conveys the cable, the swing cylinder 32 can drive the clamping portion 31 to swing through the connecting arm 33, thereby ensuring that the conveying mechanism 30 can drag out the cable wound on the reel mechanism 20, thereby improving the efficiency of unwinding or rewinding the cable.

[0037] In this embodiment, the connecting arm 33 is telescopically arranged to support the clamping portion 31, so as to facilitate adjustment of the position of the clamping portion 31 to meet different usage requirements and working conditions.

[0038] like Figure 6 As shown, the clamping part 31 includes a mounting seat 311, a clamping assembly 312 and two roller assemblies 314. Among them, the clamping assembly 312 is arranged on the mounting seat 311, and the clamping assembly 312 includes two clamping plates arranged opposite to each other, and a clamping space 313 for clamping the cable is formed between the two clamping plates, and the size of the clamping space 313 is adjustable. Two roller assemblies 314 are arranged on the mounting seat 311 and are respectively located on both sides of the clamping assembly 312, and each roller assembly 314 has a through port connected to the clamping space 313, and the through port is used for the cable to pass through. In this way, through the coordinated use of the clamping assembly 312 and the roller assembly 314, the smoothness and stability of the cable during the winding and unwinding process can be ensured, the wear and damage of the cable can be reduced, and the efficiency and safety of the operation can be improved. In the actual application of coal mines, the above-mentioned setting can effectively avoid the problems of tangling and wear of the cable during the winding and unwinding process, and ensure the integrity of the cable, which is very important for the long-term stable operation of the coal mine cable system.

[0039] In this embodiment, the clamping assembly 312 can adapt to cables of different sizes, thereby improving the versatility of the clamping assembly 312. The above-mentioned configuration of the roller assembly 314 converts the sliding friction between the cable and the mounting seat 311 into rolling friction between the cable and the roller assembly 314, so as to reduce the wear of the cable.

[0040] like Figure 6 As shown, each roller assembly 314 includes a bracket 3141, two first rollers 3142 arranged oppositely, and two second rollers 3143 arranged oppositely. The two first rollers 3142 arranged oppositely are rotatably arranged on the bracket 3141. The two second rollers 3143 arranged oppositely are rotatably arranged on the bracket 3141. Among them, the two first rollers 3142 are located between the two second rollers 3143 and the clamping assembly 312, and the rotating shafts of each first roller 3142 and the rotating shafts of each second roller 3143 are arranged at an angle. In this way, the above-mentioned setting can effectively guide the direction of the cable, reduce the friction and distortion of the cable during the winding and unwinding process, and improve the service life of the cable and the reliability of the equipment. At the same time, in the winding and unwinding application of long-distance cables in coal mines, the above-mentioned setting of the roller assembly 314 can significantly reduce the resistance of the cable during the travel process, improve the laying speed of the cable, and reduce the performance degradation of the cable caused by friction and distortion, which plays an important role in ensuring the power supply in the production process of coal mines.

[0041] like Figure 5As shown, the cable arrangement mechanism 40 also includes a frame 42, a guide column 43, a second driving device 44 and a displacement detection device. Among them, the guide column 43 is arranged on the frame 42, and the cable arrangement gantry 41 is slidably arranged on the guide column 43 along the extension direction of the guide column 43. The second driving device 44 is drivingly connected to the cable arrangement gantry 41 to drive the cable arrangement gantry 41 to slide along the guide column 43. The displacement detection device is used to detect the moving distance of the cable arrangement gantry 41. In this way, the above-mentioned cable arrangement mechanism 40 can accurately control the arrangement of the cable, avoid the disorderly winding and entanglement of the cable, and improve the cable winding quality and the intelligent level of the equipment. At the same time, the above-mentioned arrangement of the cable arrangement mechanism 40 plays a key role in the coal mine environment. By automatically adjusting the arrangement of the cables, it effectively prevents the mutual squeezing and damage between the cables, improves the accuracy of the cable winding operation, and reduces the production interruption caused by cable failure.

[0042] In this embodiment, the cable winding and unwinding mechanism includes a control module, and the conveying mechanism 30 also includes a second pressure detection device. The second pressure detection device is arranged on at least one clamping plate to detect the clamping force of the clamping plate. The second pressure detection device is electrically connected to the control module; when the pressure detection value of the second pressure detection device is greater than or equal to the preset pressure value, the clamping assembly 312 is controlled by the control module to release the cable. In this way, the above-mentioned pressure detection and control mechanism can ensure the safety of the cable during the clamping process, avoid damage to the cable due to excessive clamping force, and improve the safety of cable use and the reliability of the equipment. At the same time, in the precise winding and unwinding process of coal mine cables, the above-mentioned setting can effectively prevent the cable from being damaged due to excessive clamping, improve the efficiency and safety of cable use, reduce the frequency of cable maintenance and replacement, and have a significant effect on reducing coal mine operating costs and improving production efficiency.

[0043] In this embodiment, the automatic cable release operation of the cable winding and releasing mechanism is as follows:

[0044] First, adjust the cable gantry 41 on the cable arranging mechanism 40 to correspond to the position of the cable head, and then adjust the conveying mechanism 30 to correspond to the position of the cable laying required by the coal wall. Then guide the cable through the cable gantry 41 and the clamping space 313, and finally fix the cable head on the coal wall; then, the worker presses the start button, the conveying mechanism 30 starts to work, and pulls the cable out of the drum mechanism 20. The first pressure detection device 26 detects the cable pulling force borne by the cable in real time to ensure the safety of the workers and the cable. Specifically, the drum mechanism 20 is driven by the conveying mechanism 30 to rotate passively. While rotating, the number of turns detection device 27 detects the number of turns of the drum 21 in real time, and transmits the number of turns signal to the control module. The control module transmits the command to the cable arranging mechanism 40 to control the cable arranging gantry 41 to cooperate with the drum mechanism 20 to move the specified displacement, and transmits the completion signal to the control module. When the completion signal reaches the set value, the control module transmits the reverse displacement command to the cable arranging mechanism 40 to control the cable arranging gantry 41 to cooperate with the drum mechanism 20 to move the specified displacement in the reverse direction, and transmits the completion signal to the control module. In this way, the cable gantry 41 moves left and right to cooperate with the conveying mechanism 30 to automatically complete the cable laying operation under the control of the control module. While completing the cable laying operation, the turn number detection device 27 can integrate the number of turns of each layer of cables to calculate the total length of the cable. In this way, the worker only needs to start the cable with one button to complete the total length recording and automatic cable laying operation.

[0045] In this embodiment, the automatic cable winding operation of the cable winding and unwinding mechanism is as follows:

[0046] First, guide the cable through the clamping space 313 of the conveying mechanism 30, then through the cable gantry 41 on the cable arranging mechanism 40, and finally fix the cable head on the cable fixing clamp of the drum mechanism 20. Then adjust the cable gantry 41 to correspond to the position of the cable fixing clamp, and then adjust the conveying mechanism 30 to correspond to the position where the cable is required to be laid on the coal wall. After that, the worker presses the start button, and the drum mechanism 20 starts to work, automatically rolling the cable into the inside of the drum mechanism 20. The first pressure detection device 26 detects the cable winding force borne by the cable in real time to ensure the safety of the workers and the cable. The drum 21 rotates under the drive of the first driving device 23. While rotating, the number of turns detection device 27 detects the number of turns of the drum in real time and transmits the number of turns signal to the control module. The control module transmits the command to the cable arranging mechanism 40 to control the cable gantry 41 to cooperate with the drum mechanism 20 to move the specified displacement and transmit the completion signal to the control module. When the completion signal reaches the set value, the control module transmits the reverse displacement instruction to the cable arrangement mechanism 40 to control the cable arrangement gantry 41 to cooperate with the reel mechanism 20 to move the specified displacement in the reverse direction, and transmits the completion signal to the control module. In this way, the cable arrangement gantry 41 moves left and right to cooperate with the conveying mechanism 30 to automatically complete the cable winding operation under the control of the control module. While completing the cable winding operation, the turn detection device 27 can integrate the turn records of each layer of cables to calculate the total length of the cable. In this way, the worker only needs to start the cable with one button to complete the total length recording and automatic cable laying operation.

[0047] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0048] The entire process is completed automatically by the control system, which reduces the probability of safety accidents occurring during work, reduces the labor intensity of workers, improves working conditions, and realizes the automation of cable laying and recycling.

[0050] The present application also provides a cable winding and unwinding vehicle for coal mines (not shown), comprising the above-mentioned cable winding and unwinding mechanism.

[0051] Optionally, the cable reeling vehicle for coal mines also includes a tractor and a traveling part. The rear of the tractor is connected to the front of the chassis 10 of the cable reeling mechanism. The traveling part is arranged below the chassis 10. In this way, by adding the tractor and the traveling part, the cable reeling vehicle for coal mines can move autonomously, which is suitable for long-distance transportation and laying of coal mine cables, improves the mobility of the equipment and the flexibility of operation, can adapt to the complex terrain and working environment of coal mines, and reduces the difficulty and time cost of cable laying.

[0052] Optionally, the traveling part adopts anti-skid, shock-absorbing and high-load-carrying wheel sets, which ensures the stability and safety of the cable reel in complex terrains, avoids cable damage caused by terrain or equipment problems, and makes a significant contribution to the improvement and optimization of the coal mine cable management system.

[0053] Optionally, the chassis connection between the traction vehicle and the cable winding and unwinding mechanism can not only provide power, but also exchange data with the control module through wireless communication technology to achieve remote monitoring and operation, further improving the intelligence level and operating efficiency of the equipment, helping coal mines to achieve the goals of intelligent management and unmanned operation, and having a far-reaching impact on improving the safety and economy of coal mine production.
