Description

Technical Field

[0001] This invention relates to the field of tunnel construction technology, specifically to a composite TBM (Tunnel Boring Machine) construction battery vehicle anti-slip device. Background Technology

[0002] TBM is a factory-produced, assembly-line tunnel construction equipment that integrates mechanical, electrical, hydraulic, and pneumatic systems. Traditional drill-and-blast methods are difficult to use in tunnels with complex terrain. TBMs can be used for tunneling, support, and muck removal and can operate continuously. They have advantages such as fast tunneling speed, environmental friendliness, and high overall efficiency. They are widely used in railway, hydropower, transportation, and mining projects in China. Composite TBMs are mainly suitable for rock-based, soil, fractured zones, and alternating soft and hard strata. They are a type of tunneling machine that incorporates the principles and advantages of earth pressure balance shield tunneling and pneumatic shield tunneling, and can be used for tunnel construction in various soil types, rock strata, and alternating soft and hard strata. During construction, transportation within the tunnel is a crucial aspect of the overall project. Electric vehicles are primarily used for transport within the tunnel. However, when these vehicles are on a slope, their simple structure makes them prone to slipping. This slippage can endanger equipment and personnel below, necessitating anti-slippage devices. However, existing anti-slippage devices suffer from difficulties in disassembly and assembly, inconvenience in use, and unreliable anti-slippage performance. Summary of the Invention

[0003] The purpose of this invention is to provide a composite anti-slip device for TBM construction electric vehicles to solve the problems mentioned in the background art.

[0004] To solve the above-mentioned technical problems, the present invention provides the following technical solution: The anti-slip device includes a quick-release device, which is installed under the trolley. A braking device is installed below the quick-release device, and a deployment device is rotatably connected to the braking device. A limiting device is internally connected to the braking device. The quick-release device avoids the cumbersome process of traditional disassembly and assembly requiring screws and tools, allowing for convenient and quick installation of the anti-slip device. It also minimizes the risk of damage to parts during disassembly and assembly. The braking device acts on the track; when the trolley stops on the track, the braking device clamps the track, preventing the trolley from moving. The deployment device increases the contact area between the braking device and the track, thereby increasing friction. The limiting device clamps the wheels simultaneously with the braking device clamping the track, restricting wheel rotation.

[0005] The quick-release device includes a housing and an umbrella-shaped column. A mounting plate is connected to the top of the housing and is installed below the trolley. A locking tongue is installed in a sliding groove inside the housing, and a spring is slidably connected to the locking tongue. One end of the spring rests against the sliding groove. A ball bearing is slidably connected to the umbrella-shaped column, which is slidably connected to a groove inside the housing. A cylinder is installed below the umbrella-shaped column, and a connecting plate is installed below the cylinder. The connecting plate is installed above the braking device. When installing the anti-slip device, the umbrella-shaped column is pushed into the groove of the housing. When the umbrella surface of the umbrella-shaped column slides below the locking tongue, the umbrella surface abuts against the locking tongue, causing the locking tongue to compress the spring and slide backward in the sliding groove. When the umbrella surface slides above the locking tongue, the spring extends, causing the locking tongue to slide forward and abut against the bottom of the umbrella surface. To remove the anti-slip device, push the umbrella-shaped column upwards from the locked position until the latch is against the bottom of the ball bearing. Then push the umbrella-shaped column downwards, and the latch will move the ball bearing upwards until the top of the ball bearing enters the arc-shaped groove under the umbrella surface. The bottom of the ball bearing abuts against the latch, and the latch will compress the spring and slide backwards in the sliding groove until the top of the ball bearing is completely inside the arc-shaped groove. The latch can then be moved onto the umbrella surface, and the anti-slip device can be removed from the housing.

[0006] The braking device includes a mounting block installed below a connecting plate. A clamping block is slidably connected within the telescopic groove of the mounting block, and the clamping block is connected to a limiting device. A clamping structure is rotatably connected to the mounting block, and the clamping structure is slidably connected to the clamping block. A cylinder is mounted above the clamping structure, and a push plate is installed between the clamping structure and the cylinder. The cylinder is installed below the connecting plate and is connected to a control system. When braking is required, the cylinder rod retracts, causing the clamping structure to rotate and the clamping block to slide towards the center within the telescopic groove, thereby clamping the track.

[0007] The clamping structure includes a column with bolts installed inside. A push plate is installed between the column and the cylinder. The bolts slidably connect sliding plates one and two, which are installed in movable grooves within these plates. A lever is installed on one side of each sliding plate, with one end of the lever installed in a push-pull groove of the clamping block. Sliding plates one and two are rotatably connected to the mounting block via a rotating shaft. When braking is required, the cylinder rod retracts, causing the column to move upwards. The bolts on the column slide in the movable grooves, causing sliding plates one and two to rotate in opposite directions. The levers on sliding plates one and two then cause the clamping block to slide in the push-pull grooves.

[0008] The limiting device includes a rotating shaft, on which clamping plate one and clamping plate two are rotatably connected. A protrusion is connected to one side of clamping plate one and clamping plate two, and one side of the protrusion is connected to a clamping block. A return spring is installed between clamping plate one and clamping plate two. When the clamping block clamps, the protrusion on the clamping block drives clamping plate one and clamping plate two to rotate in opposite directions around the rotating shaft, allowing one end of clamping plate one and clamping plate two to clamp the wheel.

[0009] The unfolding device includes a lead screw and a rotating device. A motor is connected to the top of the lead screw, and a convex plate is installed below the motor. The convex plate is connected to a clamping block. A pin is threaded onto the lead screw, and a limit block is connected to one side of the pin. The limit block is connected to the clamping block. The rotating device is rotatably connected to the clamping block. A transmission structure is installed below the rotating device. The pin slides in a through groove formed when the rotating device and the clamping block are parallel. The motor is connected to a control system. When the anti-slip device is activated, the motor drives the lead screw to rotate, and the transmission structure brings the rotating device into contact with the clamping block, causing the pin on the lead screw to insert into the through groove.

[0010] The rotating device includes an unfolding plate and a rotating rod. A fixed plate is mounted above the rotating rod, and the fixed plate is connected to a clamping block. A pull rod is connected to the rotating rod. The unfolding plate and the clamping block are rotatably connected by a hinge. A transmission structure is installed below the unfolding plate. A slide rail is provided on the unfolding plate, and one end of the pull rod slides within the slide rail. When the motor rotates, the transmission structure causes the rotating rod to rotate, which in turn drives the pull rod to rotate. The pull rod slides within the slide rail, causing the unfolding plate to rotate.

[0011] The transmission structure includes a mounting groove installed inside an integrated box, which is located below a unfolding plate. An I-beam is slidably connected within the mounting groove. Two racks, a first rack and a second rack, are respectively positioned on either side of the I-beam. The first rack meshes with a large gear, and the second rack meshes with a small gear. The second rack has fewer teeth than the first rack. The large gear is connected to a lead screw, and the small gear is connected to a rotating rod. When the motor rotates, the lead screw drives the large gear to rotate, which meshes with the first rack, causing the I-beam to slide within the mounting groove. The second rack then drives the small gear to rotate, which in turn drives the rotating device to rotate.

[0012] Rubber pads are provided on one side of the clamping block and the unfolding plate. The rubber pads can increase the surface roughness, increase the friction, and at the same time reduce the damage of the braking device to the track.

[0013] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0014] The quick-release device of this invention avoids the cumbersome process of traditional disassembly and assembly requiring screws and tools. Simply pushing the anti-slip device allows for convenient and quick installation and removal, while minimizing the risk of damage to parts during assembly and disassembly. The device can be remotely started and stopped; simply starting the motor and cylinder activates the anti-slip device, eliminating the need for manual installation and making it very convenient to use. The unfolding device of this invention provides a large contact area between the braking device and the track. Rubber pads are placed on the contact surface to increase surface roughness and friction. Simultaneously, a limiting device restricts the wheels during braking, making the anti-slip effect more stable. Attached Figure Description

[0026] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0027] Please see Figure 1-9 This invention provides a technical solution: an anti-slip device includes a quick-release device 1, which is installed below the trolley. A braking device 2 is installed below the quick-release device 1, and a deployment device 3 is rotatably connected to the braking device 2. A limiting device 4 is internally connected to the braking device 2. The quick-release device 1 avoids the cumbersome process of traditional disassembly and assembly requiring screws and tools, allowing for convenient and quick installation of the anti-slip device. It also minimizes the risk of damage to parts during disassembly and assembly. The braking device 2 acts on the track; when the trolley stops on the track, the braking device 2 clamps the track, preventing the trolley from moving. The deployment device 3 increases the contact area between the braking device 2 and the track, thereby increasing friction. The limiting device 4 clamps the wheels simultaneously with the braking device 2 clamping the track, restricting wheel rotation.

[0028] The quick-release device 1 includes a housing 12 and an umbrella-shaped column 14. A mounting plate 11 is connected to the top of the housing 12 and is installed under the trolley. A locking tongue 13 is installed in a sliding groove inside the housing 12. A spring is slidably connected to the locking tongue 13, with one end of the spring resting against the sliding groove. A ball bearing 15 is slidably connected to the umbrella-shaped column 14 and is slidably connected to a groove inside the housing 12. A cylinder is installed below the umbrella-shaped column 14, and a connecting plate 16 is installed below the cylinder. The connecting plate 16 is installed above the braking device 2. When installing the anti-slip device, the umbrella-shaped column 14 is pushed into the groove of the housing 12. When the umbrella surface of the umbrella-shaped column 14 slides below the locking tongue 13, the umbrella surface abuts against the locking tongue 13, and the locking tongue 13 will compress the spring and slide backward in the sliding groove. When the umbrella surface slides above the locking tongue 13, the spring extends, causing the locking tongue 13 to slide forward and abut against the bottom of the umbrella surface. When removing the anti-slip device, push the umbrella-shaped column 14 upward from the locked position until the locking tongue 13 is against the bottom of the ball bearing 15. Then push the umbrella-shaped column 14 downward, and the locking tongue 13 will move the ball bearing 15 upward until the top of the ball bearing 15 enters the arc-shaped groove under the umbrella surface. The bottom of the ball bearing 15 abuts against the locking tongue 13, and the locking tongue 13 will squeeze the spring and slide backward in the sliding groove until it slides until the top of the ball bearing 15 is completely in the arc-shaped groove. Then the locking tongue 13 can be moved to the umbrella surface, and the anti-slip device can be removed from the outer casing 12.

[0029] The braking device 2 includes a mounting block 22, which is installed below the connecting plate 16. A clamping block 21 is slidably connected in the telescopic groove of the mounting block 22, and a rubber gasket is provided on one side of the clamping block 21. The rubber gasket can increase the surface roughness and increase the friction. The clamping block 21 is connected to the limiting device 4. The mounting block 22 is rotatably connected to the clamping structure 23. The clamping structure 23 is slidably connected to the clamping block 21. A cylinder 24 is installed above the clamping structure 23. A push plate is installed between the clamping structure 23 and the cylinder 24. The clamping structure 23 includes a column 234. A bolt 235 is installed inside the column 234. A push plate is installed between the column 234 and the cylinder 24. The bolt 235 is slidably connected to a sliding plate 1 232 and a sliding plate 233. The bolt 235 is installed in the movable groove of the sliding plate 1 232 and the sliding plate 233. A lever 231 is installed on one side of the sliding plate 1 232 and the sliding plate 233. One end of the lever 231 is installed in the push-pull groove of the clamping block 21. The sliding plate 1 232 and the sliding plate 233 are rotatably connected to the mounting block 22 via a rotating shaft. When braking is required, the cylinder rod of cylinder 24 retracts, causing the column 234 to move upward. The bolt 235 on the column 234 slides in the push-pull groove, causing sliding plate 1 232 and sliding plate 233 to rotate in opposite directions. The lever 231 on sliding plate 1 232 and sliding plate 233 causes the clamping block 21 to slide in the telescopic groove. Cylinder 24 is installed below the connecting plate 16 and is connected to the control system. When braking is required, the cylinder rod of cylinder 24 retracts, causing the clamping structure 23 to rotate, causing the clamping block 21 to slide towards the center in the telescopic groove, thereby clamping the track.

[0030] The limiting device 4 includes a rotating shaft, which rotatably connects a first clamping plate 41 and a second clamping plate 42. A protrusion is connected to one side of each clamping plate 41 and the second clamping plate 42, and one side of the protrusion is connected to a clamping block 21. A return spring 43 is installed between the first clamping plate 41 and the second clamping plate 42. When the clamping block 21 clamps, the protrusion on the clamping block 21 drives the first clamping plate 41 and the second clamping plate 42 to rotate in opposite directions around the rotating shaft, allowing one end of the first clamping plate 41 and the second clamping plate 42 to clamp the wheel.

[0031] The unfolding device 3 includes a lead screw 32 and a rotating device 34. A motor 31 is connected above the lead screw 32, and a convex plate is installed below the motor 31. The convex plate is connected to the clamping block 21. A pin 33 is threaded onto the lead screw 32, and a limit block 36 is connected to one side of the pin 33. The limit block 36 is connected to the clamping block 21. The rotating device 34 is rotatably connected to the clamping block 21. The rotating device 34 includes an unfolding plate 343 and a rotating rod 344. A fixing plate 341 is installed above the rotating rod 344 and is connected to the clamping block 21. A pull rod 342 is connected to the rotating rod 344. The unfolding plate 343 and the clamping block 21 are rotatably connected by a hinge. A rubber pad is provided on one side of the unfolding plate 343 to increase surface roughness and friction. A transmission structure 35 is installed below the unfolding plate 343, and a slide rail 37 is provided on the unfolding plate 343. One end of the pull rod 342 slides within the slide rail 37. When the motor 31 rotates, the transmission structure 35 causes the rotating rod 344 to rotate, which in turn drives the pull rod 342 to rotate. The pull rod 342 slides within the slide rail 37, causing the unfolding plate 343 to rotate. The transmission structure 35 is installed below the rotating device 34. The transmission structure 35 includes a mounting groove 353, which is installed inside the integrated box. The integrated box is installed below the unfolding plate 343. An I-beam plate 354 is slidably connected within the mounting groove 353. A rack and a rack are respectively provided on both sides of the I-beam plate 354. Rack 1 meshes with a large gear 351, and rack 2 meshes with a small gear 352. Rack 2 has fewer teeth than rack 1. The large gear 351 is connected to the lead screw 32, and the small gear 352 is connected to the rotating rod 344. When motor 31 rotates, lead screw 32 drives large gear 351 to rotate. Large gear 351 meshes with rack 1, causing I-plate 354 to slide in mounting groove 353. Rack 2 drives small gear 352 to rotate, and small gear 352 drives rotating device 34 to rotate. Pin 33 can slide in the through groove formed when rotating device 34 is parallel to clamping block 21. Motor 31 is connected to control system. When anti-slip device is activated, motor 31 drives lead screw 32 to rotate, and through transmission structure 35, rotating device 34 contacts clamping block 21, and pin 33 on lead screw 32 inserts into through groove.

[0032] Working principle of the invention:

[0033] When the trolley stops, the operator controls the cylinder 24 and motor 31 to start through the control system. When the cylinder rod of cylinder 24 retracts, the push plate of cylinder 24 drives the column 234 to retract upward. The bolt 235 on the column 234 slides in the push-pull groove, causing the left plate 232 and right plate 233 to rotate in opposite directions. The lever 231 on the left plate 232 and right plate 233 drives the clamping block 21 to slide in the telescopic groove. The two clamping blocks 21 move in opposite directions and clamp on the track. When the two clamping blocks 21 move in opposite directions, the protrusion on the clamping block 21 drives the upper plate 41 and lower plate 42 to rotate in opposite directions around the rotating shaft 43, so that one end of the upper plate 41 and lower plate 42 can clamp the wheel and restrict the rotation of the wheel. When motor 31 starts, it drives lead screw 32 to rotate, which in turn drives pin 33 to move downwards. Because limit block 36 blocks pin 33, pin 33 cannot rotate. Simultaneously, lead screw 32 drives large gear 351 to rotate. Large gear 351 meshes with rack 354, causing rack 354 to slide in mounting groove 353. Rack 354 then drives small gear 352 to mesh and rotate. Small gear 352 drives rotating rod 344 to rotate, which in turn drives pull rod 342 to rotate. One end of pull rod 342 is in slide rail 37 of unfolding plate 343. The inner sliding mechanism drives the unfolding plate 343 to rotate around the hinge. When the unfolding plate 343 moves to the same plane as the clamping block 21, since the number of teeth of the rack 354 on the side of the small gear 352 is less than the number of teeth of the rack 354 on the side of the large gear 351, the small gear 352 and the rack 354 stop meshing and the small gear 352 stops rotating. At this time, the pin 33 just moves to the top of the through slot, and the large gear 351 continues to drive the rack 354 to mesh until the pin 33 enters the through slot and the motor 31 stops rotating, thus making the trolley stably fixed on the track.

[0034] When the trolley moves again, the operator controls the cylinder 24 and motor 31 to start through the control system. The cylinder rod of cylinder 24 extends, and the push plate of cylinder 24 drives the column 234 to extend downward. The bolt 235 on the column 234 slides during the push and pull, causing the left plate 232 and right plate 233 to rotate in opposite directions. The lever 231 on the left plate 232 and right plate 233 drives the clamping block 21 to slide in the telescopic groove. The two clamping blocks 21 move in opposite directions and are released from the track. When the two clamping blocks 21 move in opposite directions, the protrusion on the clamping block 21 drives the upper plate 41 and lower plate 42 to rotate in opposite directions around the rotating shaft 43, so that one end of the upper plate 41 and lower plate 42 can release the wheel. Motor 31 rotates in the opposite direction, driving lead screw 32 to rotate. Lead screw 32 drives pin 33 to move upward. When pin 33 just moves above the through slot, pinion 352 and rack 354 begin to mesh. Pinion 352 drives rotating rod 344 to rotate. Rotating rod 344 drives pull rod 342 to rotate. One end of pull rod 342 slides in slide rail 37 of unfolding plate 343, causing unfolding plate 343 to rotate around hinge. When unfolding plate 343 moves to be perpendicular to clamp block 21, motor 31 stops rotating.

Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention without departing from the principles and spirit of the present invention.
