Description

Technical Field

[0001] This utility model relates to the field of cable platform technology, specifically a cable placement platform for a tunneling machine towing conveyor tail. Background Technology

[0002] During underground production, the belt conveyor moves along with the tunneling machine as it tunnels, and the distance between the tunneling machine and the belt conveyor changes constantly. At this time, the cable needs to be retracted and extended in a timely manner. Therefore, a platform is installed on the belt conveyor to place the cable so as to facilitate power supply between the tunneling machine and the belt conveyor.

[0003] Currently, the orientation of the reel installed on the platform is fixed, while the position of the tunneling machine's excavator head is variable. This can cause problems for workers during cable winding due to misalignment. For example, when the tunneling machine's excavator head changes from digging straight ahead to digging to the left, the position of the excavator head changes, but the reel is still facing straight ahead. This makes it very inconvenient for workers to wind up the cable. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a cable placement platform for the tail of a tunneling machine's conveyor belt. The winding drum in the cable placement platform can be adjusted in real time according to the position of the excavator head of the tunneling machine. By rotating the central shaft, the winding direction of the winding drum is made to face the head of the tunneling machine, which makes it more convenient and faster for the workers to wind up the cable.

[0005] The technical solution of this utility model is implemented as follows:

[0006] A cable placement platform for moving the tail of a tunneling machine conveyor belt includes a foot platform fixedly installed at the tail of the conveyor belt, on which a winding drum is placed, and a cable for powering the tunneling machine is wound inside the winding drum.

[0007] The winding drum is located inside a rotating support drum that is fixedly installed on the stepping platform; a central shaft runs through the center of the winding drum, and the winding drum can rotate freely around the central shaft;

[0008] Annular limiting grooves are provided at both ends of the central shaft, and the annular limiting grooves support the top of the rotating support cylinder; the winding drum is concentrically arranged with the rotating support cylinder, and the winding drum can rotate and adjust its direction with the rotating support cylinder as the center by means of the annular limiting grooves.

[0009] Using the above solution, the winding drum in the cable placement platform can be adjusted in real time according to the position of the excavator head of the tunneling machine. By rotating the central shaft, the winding direction of the winding drum is made to face the head of the tunneling machine, making it more convenient and faster for workers to wind up the cable.

[0010] In a preferred embodiment of a cable placement platform for a tunneling machine towing conveyor tail section, all surfaces of the annular limiting groove that come into contact with the rotating support cylinder are polished surfaces.

[0011] By adopting the above solution, the contact surfaces are polished to facilitate the rotation of the central shaft. This greatly reduces the friction between the two surfaces, making it easier to rotate the central shaft.

[0012] As a preferred embodiment of a cable placement platform for a tunneling machine towing conveyor tail, vertically arranged mounting holes are provided on the shafts at both ends of the central shaft. A wheel frame is installed in the mounting hole, and an anti-detachment caster located inside the rotating support cylinder is rotatably installed at the bottom of the wheel frame. The anti-detachment caster is always in contact with the inner wall of the rotating support cylinder.

[0013] To prevent the central shaft from detaching from the rotating support cylinder, two sets of anti-detachment casters are installed on the central shaft. The anti-detachment casters rotate with the central shaft in real time, thereby preventing the central shaft from detaching from the rotating support cylinder.

[0014] In a preferred embodiment of a cable placement platform for a tunneling machine towing conveyor tail section, a stop pin is inserted at the top of the wheel frame to prevent the wheel frame from falling. Both ends of the stop pin are threaded with nuts to prevent them from coming off.

[0015] By adopting the above solution, in order to facilitate better anti-slip casters, when the anti-slip casters need to be replaced due to excessive wear, simply remove the blocking pin to easily replace the new anti-slip casters.

[0016] As a preferred embodiment of a cable placement platform for a tunneling machine towing conveyor tail, linear limiting grooves are provided on the shaft heads at both ends of the central shaft, and L-shaped positioning pins are installed in the linear limiting grooves. Multiple circumferentially arrayed insertion holes are provided on the side wall of the rotating support cylinder, which are used in conjunction with the L-shaped positioning pins. When the L-shaped positioning pins are inserted into the insertion holes, the central shaft is completely fixed.

[0017] There are a total of 36 sockets, with a horizontal angle of 10° between each pair of adjacent sockets.

[0018] The top of the L-shaped positioning pin is fixed with a stop to prevent the L-shaped positioning pin from falling down.

[0019] By adopting the above scheme, in order to fix the central shaft after rotation, the central shaft is rotated to the nearest target socket so that the L-shaped positioning pin is inserted into the socket, thus completing the fixation of the central shaft.

[0020] In a preferred embodiment of a cable placement platform for a tunneling machine towing conveyor tail section, annular throttles for driving the winding drum to rotate are fixed on both sides of the winding drum.

[0021] Using the above solution, in order to facilitate the operation of the winding drum by the staff, the winding drum can be driven to rotate by rotating the ring handles on both sides, thereby realizing the winding and unwinding of the cable on the winding drum.

[0022] After adopting the above technical solution, the beneficial effects of this utility model are:

[0023] 1. The reel in the cable placement platform can be adjusted in real time according to the position of the excavator head of the tunneling machine. By rotating the central shaft, the reel can be wound in the direction of the excavator head, making it more convenient and faster for workers to reel in the cable.

[0024] 2. To facilitate the rotation of the central shaft, the contact surfaces are polished. This greatly reduces the friction between the two surfaces, making it easier to rotate the central shaft.

[0025] 3. To prevent the central shaft from falling off the rotating support, two sets of anti-slip casters are installed on the central shaft. The anti-slip casters rotate with the central shaft in real time to prevent the central shaft from falling off the rotating support.

[0026] 4. To facilitate better anti-slip casters, when anti-slip casters need to be replaced due to excessive wear, simply remove the retaining pin to easily replace the new anti-slip caster;

[0027] 5. In order to fix the central shaft after rotation, rotate the central shaft to the nearest target socket so that the L-shaped positioning pin is inserted into the socket, thus fixing the central shaft.

[0028] 6. To facilitate the operation of the reel, the reel can be driven to rotate by rotating the ring handles on both sides, thereby enabling the cable to be wound up and unwound on the reel. Attached Figure Description

Detailed Implementation

[0037] 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.

[0038] like Figures 1 to 4 As shown, a cable placement platform for a tunneling machine towing conveyor tail includes a foot platform 1 fixedly installed at the tail of the conveyor. A winding drum 2 is placed on the foot platform 1, and a cable 3 for powering the tunneling machine is wound inside the winding drum 2. The winding drum 2 is located inside a rotating support drum 4 fixedly installed on the foot platform 1. A central shaft 5 passes through the center of the winding drum 2, allowing the winding drum 2 to rotate freely around the central shaft 5. Annular limiting grooves 6 are respectively provided at both ends of the central shaft 5, supporting the top of the rotating support drum 4. The winding drum 2 and the rotating support drum 4 are concentrically arranged, and the winding drum 2 can rotate and adjust its direction around the rotating support drum 4 using the annular limiting grooves 6. The winding drum 2 in this cable placement platform can be adjusted in real time according to the position of the tunneling machine's excavator head. By rotating the central shaft 5, the winding direction of the winding drum 2 is directed towards the tunneling machine's head, making cable winding more convenient and faster for workers.

[0039] like Figure 4 As shown, all surfaces of the annular limiting groove 6 that come into contact with the rotating support cylinder 4 are polished surfaces. To facilitate the rotation of the central shaft 5, the above-mentioned contact surfaces are polished, which greatly reduces the friction between the two, making it easier to rotate the central shaft 5.

[0040] like Figures 4 to 5 As shown, vertically arranged mounting holes 7 are provided on both ends of the central shaft 5. A wheel frame 8 is installed inside each mounting hole 7, and an anti-detachment caster 9 is rotatably mounted on the bottom end of the wheel frame 8, located inside the rotating support cylinder 4. The anti-detachment caster 9 is always in contact with the inner wall of the rotating support cylinder 4. To prevent the central shaft 5 from detaching from the rotating support cylinder 4, two sets of anti-detachment casters 9 are installed on the central shaft 5. The anti-detachment casters 9 rotate with the central shaft 5 in real time, thereby preventing the central shaft 5 from detaching from the rotating support cylinder 4.

[0041] like Figures 4 to 5 As shown, a stop pin 10 is inserted into the top of the wheel frame 8 to prevent the wheel frame 8 from falling. Both ends of the stop pin 10 are threaded with nuts 11 to prevent it from coming off. To facilitate better anti-slip casters 9, when anti-slip casters 9 need to be replaced due to excessive wear, simply remove the stop pin 10 to easily replace them with new anti-slip casters 9.

[0042] like Figure 4 , Figure 6 As shown, linear limiting grooves 12 are provided on both ends of the central shaft 5. L-shaped positioning pins 13 are installed within these grooves. Multiple circumferentially arrayed insertion holes 14 are provided on the side wall of the rotating support cylinder 4, which cooperate with the L-shaped positioning pins 13. When the L-shaped positioning pins 13 are interference-fitted into the insertion holes 14, the central shaft 5 is completely fixed. There are thirty-six insertion holes 14 in total, with a horizontal angle of 10° between each pair of adjacent insertion holes 14. A stop handle 15 is welded to the top of the L-shaped positioning pins 13 to prevent them from falling. To fix the central shaft 5 after rotation, rotate the central shaft 5 to the nearest target insertion hole 14, allowing the L-shaped positioning pins 13 to be inserted into the insertion holes 14, thus completing the fixation of the central shaft 5.

[0043] like Figure 4 , Figure 6 As shown, annular handles 16 for driving the winding drum 2 to rotate are welded and fixed on both sides of the winding drum 2. In order to facilitate the operator to rotate the winding drum 2, the winding drum 2 can be driven to rotate by rotating the annular handles 16 on both sides, thereby realizing the winding and unwinding of the cable 3 on the winding drum 2.

[0044] The working principle of this utility model:

[0045] During application, a worker stands on the foot platform 1 and is responsible for adjusting the orientation of the winding drum 2 in real time. When the excavator head of the tunneling machine is in a certain position, the winding drum 2 is adjusted to face the excavator head accordingly.

[0046] When adjusting the winding drum 2, rotate the central shaft 5. At this time, the limiting groove rotates around the rotating support drum 4. The anti-detachment caster 9 rotates with the central shaft 5 in real time to prevent the central shaft 5 from falling off the rotating support drum 4. Rotate the central shaft 5 to the nearest target insertion hole 14 so that the L-shaped positioning pin 13 is inserted into the insertion hole 14, thus completing the fixation of the central shaft 5. At this time, the winding direction of the winding drum 2 is facing the head of the tunneling machine, which makes it more convenient and faster for the workers to wind up the cable.

[0047] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
