Description

Technical Field

[0001] The utility model relates to the field of tunnel boring machine towing cables, in particular to a tunnel boring machine towing cable device for a tunneling working face. Background Art

[0002] A roadheader is a mechanical device used to cut and remove rock or soil in underground engineering and mining operations. They are used to dig tunnels, mines or underground passages, and can efficiently carry out excavation work in underground environments. There are many types of roadheaders, such as pick-type roadheaders, shield machines and chain roadheaders, each of which has specific uses and designs to adapt to different geological conditions and engineering needs. During the excavation process, in order to ensure the quality and flatness of the tunnel engineering, the excavation face needs to move back and forth to pull the bottom and sweep the side, so the roadheader needs to be connected to the machine cable when in use, and a towing cable device is required to prevent cable damage. A towing cable device is a device used in underground engineering and mining operations to install and maintain cables, optical cables or other types of conductors. It can effectively pull the cable from one end to the other, especially when operating over longer distances or in difficult environments. Towing cable devices are commonly used in the construction of power, communications, mining, tunnels and other underground infrastructure.

[0003] In traditional cable-drag devices for tunnel boring machines, the drum is used to wind and release the cable, and can be electrically, hydraulically or manually driven. The guide device includes a guide wheel or a guide belt to ensure the smooth passage of the cable and prevent the cable from being entangled or worn. The support structure provides stability and support for the equipment, ensuring the stability and reliability of each component during operation. The cable will swing left and right when being dragged, and the inertia of the swing drives the slide rail on which the cable is suspended to swing, making the support frame fixed to the slide rail easy to deform and damage, and then causing the cable to fall onto the belt conveyor, affecting the normal operation of related equipment and causing safety accidents. Therefore, a cable-drag device for tunnel boring machines on the tunneling working face is proposed to solve the above problems. Utility Model Content

[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] Reference Figure 1 - Figure 3 , the utility model provides an embodiment: a cable towing device for a tunneling machine on a tunneling working face, comprising a mounting plate 1, a support frame 2 is fixedly connected to the upper surface of the mounting plate 1, a winding drum 3 is rotatably connected between the support frames 2, the winding drum 3 is used to prevent the cable, a motor 4 is arranged on the side wall of the support frame 2, the output end of the motor 4 is connected to the winding drum 3, a support rod 1 5 is fixedly connected to the upper surface of the support frame 2, the support rod 1 5 is used to fix the cable, a support rod 2 6 is fixedly connected to the upper surface of the support frame 2, a fixing plate 7 is fixedly connected between the support rods 2 6, a fixing ring 8 is rotatably connected to the side wall of the fixing plate 7, and a fixing ring 8 is fixedly connected to the fixing plate 7.

[0032] When operating the device, the screw 13 is first driven to rotate by rotating the rotating block. As the screw 13 rotates, the fixed block 14 fixed on the side wall of the screw 13 moves along the thread direction. The movement of the fixed block 14 further causes the rotation of the fixed ring 8. When the fixed ring 8 rotates, it drives the slide 11 inside the fixed frame 10 to move. The distance between the slides 11 can be adjusted in this way to clamp the cable. This clamping ensures that when the cable is hung inside the sliding sleeve 17, even if the cable is extended due to external force, it will not shake. The elimination of shaking avoids the problem of cable falling, thereby ensuring that the relevant equipment will not be adversely affected by the shaking of the cable during operation, thereby ensuring the normal working state of the equipment.

[0033] Reference Figure 2 and Figure 4A fixing column 18 is fixedly connected to the upper surface of the mounting plate 1, and a mounting block 19 is arranged on the upper surface of the fixing column 18. The mounting block 19 is used to install a wiping sponge 20. The side wall of the mounting block 19 is fixedly connected to a wiping sponge 20. The wiping sponge 20 is used to clean the cable. A sliding assembly is arranged between the support rods 5. The sliding assembly is used to fix the cable to move. The sliding assembly includes a steel wire rope 16 and a sliding sleeve 17. The sliding sleeve 17 is used to fix the cable. The side wall of the steel wire rope 16 is fixedly connected between the support rods 5. The sliding sleeve 17 is internally slidably connected to the side wall of the steel wire rope 16. The side wall of the mounting block 19 is fixed with a connecting frame 21. The side wall of the connecting frame 21 is provided with a card block 23. The connecting frame 2 1 is provided with a first spring 22, one end of the first spring 22 is fixedly connected to the inside of the connecting frame 21, the other end of the first spring 22 is fixedly connected to the side wall of the screw rod 13, the side wall of the connecting frame 21 is slidably connected to the inside of the fixing column 18, the side wall of the fixing column 18 is fixedly connected to a connecting block 24, the inside of the connecting block 24 is slidably connected to an extrusion plate 25, the extrusion plate 25 is used to extrude the card block 23, the side wall of the extrusion plate 25 is fixedly connected to a handle 26, the handle 26 is used to extrude the extrusion plate 25, the side wall of the handle 26 is sleeved with a second spring 27, one end of the second spring 27 is fixedly connected to the side wall of the extrusion plate 25, the other end of the second spring 27 is fixedly connected to the inside of the connecting block 24;

[0034] During long-term use, dust and other impurities will accumulate on the outer wall of the cable. When the cable is retracted, the wiping sponge 20 is used to clean it. After a period of use, the wiping sponge 20 accumulates a lot of dust and needs to be replaced. By pressing the handle 26, the movement of the handle 26 will drive the squeezing plate 25 to move together. The movement of the squeezing plate 25 will apply pressure to the card block 23, so that it enters the interior of the connecting frame 21, thereby canceling the fixation of the mounting block 19, and then taking out the old wiping sponge 20 and replacing it with a new one. After the replacement is completed, the connecting frame 21 is inserted into the interior of the fixing column 18. During the insertion process, the card block 23 will be squeezed, causing the first spring 22 to contract. When the card block 23 is aligned with the concave hole in the fixing column 18, the squeezing will stop. At this time, the first spring 22 will reset and rebound, firmly clamping the card block 23 into the interior of the fixing column 18. In this way, the new wiping sponge 20 is successfully fixed in the cable cleaning system, and efficient cleaning work can continue.

[0035] Working principle: When using the device, the screw 13 is rotated by rotating the rotating block, and then the fixed block 14 is moved on the side wall of the screw 13. At the same time, the movement of the fixed block 14 causes the fixed ring 8 to rotate. The rotation of the fixed ring 8 causes the slide plate 11 inside the fixed frame 10 to move, thereby changing the distance between the slide plates 11, thereby achieving the effect of clamping the cable and ensuring that when the cable is hung inside the sliding sleeve 17, it will not shake due to the extension of the cable, thereby causing the cable to fall and affect the normal operation of related equipment.

[0036] After long-term use, dust and other impurities will adhere to the outer wall of the cable. When the cable is retracted, it is cleaned with the wiping sponge 20. When the wiping sponge 20 needs to be replaced, the handle 26 is pressed to move it. The movement of the handle 26 drives the squeezing plate 25 to move, and at the same time, the second spring 27 is stretched. The movement of the squeezing plate 25 squeezes the card block 23 to make it enter the inside of the connecting frame 21, canceling the fixation of the mounting block 19, so that the mounting block 19 is detached, and the wiping sponge 20 is replaced. After replacement, the connecting frame 21 is inserted into the fixing column 18, during which the card block 23 is squeezed and moved. The movement of the card block 23 causes the first spring 22 to contract, so that the card block 23 enters the inside of the connecting frame 21. When the card block 23 is aligned with the concave hole in the fixing column 18, the squeezing is lost, so that the first spring 22 is reset and rebounds to clamp the card block 23 into the fixing column 18, completing the fixation of the mounting block 19.

[0037] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
