Technical Field

[0001] This utility model relates to the field of auxiliary structure technology for tunnel construction, specifically to an anti-runaway iron shoe. Background Technology

[0002] As an advanced construction equipment, tunnel boring machines are widely used in urban rail transit, railway and other projects. Transportation within the track is also an important part of the tunnel boring process. During tunnel boring, battery-powered vehicles are commonly used for material transportation and personnel movement.

[0003] Electric vehicles move along tracks using pulleys at their bottom; however, when the track has a steep gradient, the vehicles are prone to slipping. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an anti-slip track shoe to solve the problem that electric vehicles are prone to slipping when the track slope is large.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: an anti-slip track shoe, used for mounting on the track and cooperating with an electric vehicle, comprising:

[0006] The iron shoe body is detachably connected to the track and has an anti-slip arc surface formed thereon for cooperating with the pulleys of the electric vehicle;

[0007] A pressure plate is disposed on the bottom side of the iron shoe body and extends outward in the length direction of the bottom side of the iron shoe body, and the pressure plate is attached to the top surface of the track.

[0008] A pressing and limiting component is detachably connected to the track and cooperates with the pressure plate to apply or release pressing force to the pressure plate.

[0009] Compared with the prior art, the present invention has the following beneficial effects:

[0010] When the electric scooter needs to be parked on a track with a certain slope, the iron shoe body is detachably connected to the track and the pressure plate is attached to the track to increase the contact surface with the track, which helps to improve assembly stability. At the same time, the pressing and limiting component applies pressure to the pressure plate to ensure that the pressure plate is stably attached to the track, further improving the assembly stability of the iron shoe body. The pulley of the electric scooter abuts against the anti-slip arc surface, and the iron shoe body prevents the electric scooter from slipping, so that the electric scooter can be stably parked on the track with a certain slope.

[0016] The present invention will be further described in detail below through specific embodiments:

[0017] like Figures 1-4 As shown in the figure, this utility model embodiment proposes an anti-slip wheel shoe for mounting on a track 9 and cooperating with an electric vehicle. It includes a wheel shoe body 1, a pressure plate 2, and a pressing and limiting component. The wheel shoe body 1 is detachably connected to the track 9 and has an anti-slip arc surface formed thereon for cooperating with the pulleys of the electric vehicle. The pressure plate 2 is disposed on the bottom side of the wheel shoe body 1 and extends outward along the length of the bottom side of the wheel shoe body 1, and the pressure plate 2 is attached to the top surface of the track 9. The pressing and limiting component is detachably connected to the track 9 and cooperates with the pressure plate 2, used to apply or release pressing force to the pressure plate 2.

[0018] When the electric scooter needs to be parked on the track 9 with a certain slope during operation, the iron shoe body 1 is detachably connected to the track 9 and the pressure plate 2 is attached to the track 9 to increase the contact surface with the track 9, which is beneficial to improving assembly stability. At the same time, the pressing and limiting component applies pressure to the pressure plate 2 to ensure that the pressure plate 2 is stably attached to the track 9, further improving the assembly stability of the iron shoe body 1. After installation, the electric scooter moves backward and the pulley of the electric scooter abuts against the anti-slip arc surface. The iron shoe body 1 prevents the electric scooter from slipping, and the electric scooter can be stably parked on the track 9 with a certain slope. This is especially effective in preventing the electric scooter from slipping in rainy or snowy weather.

[0019] To better understand the aforementioned pressing and limiting component, it will be described in detail below. For example... Figure 1 , Figure 2 as well as Figure 3As shown, according to another embodiment of the present invention, the anti-slip track shoe, wherein the pressing and limiting component is disposed on the side of the track shoe body 1 away from the anti-slip arc surface and includes a mounting frame and a lifting device 3, the mounting frame is detachably connected to the track 9 and has an installation space formed therein above the track 9, the pressure plate 2 passes through the bottom side of the installation space; the lifting device 3 is disposed in the installation space and its bottom is fixedly connected to the pressure plate 2, and an elastic telescopic member 7 is provided between the top end of the lifting device 3 and the mounting frame.

[0020] In this embodiment, the iron shoe body 1 is detachably connected to the track 9, the pressure plate 2 is attached to the track 9, and after the mounting frame is installed on the track 9, the lifting device 3 is activated. The lifting device 3 extends, the elastic telescopic component 7 retracts, and a pressing force is formed on the pressure plate 2. The pressure plate 2 transmits this pressing force to the track 9, ensuring that the pressure plate 2 can be stably attached to the track 9, thereby improving the assembly stability of the iron shoe body 1 on the track 9.

[0021] In order to make the lifting device 3 perform stable telescopic adjustment, the top of the lifting device 3 is connected to the mounting block connected to the elastic telescopic component 7. The mounting block is connected to two parallel sliding rods 5. The mounting frame has two guide holes arranged in opposite directions. The two sliding rods 5 pass through the two guide holes one by one and are slidably connected.

[0022] The guide hole is a strip-shaped hole arranged along the extension and retraction direction of the lifting device 3. When the lifting device 3 is extended or retracted, power is transmitted through the mounting block, causing the two sliding rods 5 to slide one-to-one in the two guide holes, ensuring that the elastic telescopic component 7 can be extended or retracted stably and guiding the movement direction of the lifting device 3, making the adjustment process more precise.

[0023] The lifting device 3 can be a jack, and the elastic telescopic component 7 can be a pressure spring.

[0024] To enable the mounting frame to be better assembled onto the track 9, the mounting frame includes clamps 4, blocks 6, and fasteners. There are two clamps 4, and the track 9 is sandwiched between the bottom sides of the two clamps 4. The lifting device 3 and the elastic telescopic member 7 are placed between the two clamps 4. The blocks 6 are detachably connected between the top ends of the two clamps 4, and the elastic telescopic member 7 is connected to the blocks 6. There is at least one fastener, and both are detachably connected between the two clamps 4.

[0025] In this embodiment, the mounting frame is assembled as follows:

[0026] The two sliding rods 5 pass through the two guide holes in a one-to-one correspondence, and the lifting device 3, elastic telescopic component 7 and stop block 6 are arranged sequentially between the two clamps 4;

[0027] Then, the track 9 is clamped between the bottom sides of the two clamps 4;

[0028] At this point, the stop block 6 is locked and fixed between the tops of the two clamps 4, and the fastener is also connected between the two clamps 4 to complete the installation stably.

[0029] The stop block 6 is connected to two separately arranged connecting screws 12. Each connecting screw 12 passes through a connecting hole on the top side of the two clamps 4 and is threaded with a nut. During installation, the two connecting screws 12 pass through the two connecting holes and the track 9 is clamped between the bottom sides of the two clamps 4. Then, a nut is threaded onto each connecting screw 12 to fix the stop block 6 between the tops of the two clamps 4.

[0030] In this embodiment, the number of fasteners is one, and each fastener includes a fastening screw 8. Both ends of the fastening screw 8 pass through the fastening holes opened on the two clamps 4 and are threaded with nuts.

[0031] The fastening holes are located on the bottom side of the corresponding clamp 4. During installation, after the track 9 is determined to be clamped between the bottom sides of the two clamps 4, a fastening screw 8 is used to pass through the two fastening holes, and then nuts are threaded onto both ends of the fastening screw 8 to lock the bottom sides of the two clamps 4.

[0032] In the above, the mounting frame is stably assembled onto the track 9 by fasteners and stops 6 connecting the two clamps 4.

[0033] Based on the above solution:

[0034] Each clamp 4 includes a connecting plate 10 and a rail clamp 11 connected to its bottom end. The stop block 6 and fasteners are connected to the connecting plate 10, and the rail clamp 11 cooperates with the rail 9. The fastening hole is opened on the bottom side of the corresponding connecting plate 10, and the connecting hole is opened on the top side of the corresponding connecting plate 10. One end of the pressure plate 2 is placed between the bottom ends of the two connecting plates 10. The rail clamps 11 of the two clamps 4 clamp and fix the rail 9. Specifically, the two rail clamps 11 have clamping grooves on their facing sides, and the rail 9 is clamped between the two clamping grooves for clamping and fixing.

[0035] To better understand the iron shoe body 1, it will be described in more detail below. Figure 1 and Figure 4 As shown, according to another embodiment of the present invention, the anti-slip track shoe body 1 is composed of two symmetrically arranged and spaced-apart blocks on the bottom side, a pressure plate 2 is inserted between the two blocks, and an installation and positioning structure mounted on a track 9 is formed between the pressure plate 2 and the bottom side of the two blocks.

[0036] In this embodiment, the installation and positioning structure is formed between the middle of the pressure plate 2 and the bottom sides of the two blocks. The installation and positioning structure is specifically in the shape of an inverted "U" to be stably mounted on the track 9. The top of one end of the pressure plate 2 is fixedly installed with the lifting device 3 by welding. After assembly, this end of the pressure plate 2 passes between the bottom ends of the two connecting plates 10. The other end of the pressure plate 2 is attached to the top surface of the track 9, and the top surface of this end of the pressure plate 2 is formed with an inclined surface so that the pulley of the electric vehicle can easily move from the inclined surface to the top surface of the pressure plate 2, and then the pulley of the electric vehicle abuts against the anti-slip arc surface.

[0037] The top side of the iron shoe body 1 is a right-angled triangle, the inclined surface of the right-angled triangle is located at the top of the iron shoe body 1, and the anti-slip arc surface is arranged on the inclined surface of the right-angled triangle to connect with the top surface of the pressure plate 2.

[0038] When the electric vehicle needs to be parked on track 9, which has a certain slope, during operation:

[0039] First, the mounting and positioning structure formed on the bottom side of the iron shoe body 1 is set up on the track 9 at the position where the electric vehicle needs to stop, and the pressure plate 2 is attached to the top of the track 9;

[0040] Then, the two sliding rods 5 are passed through the two guide holes one by one, and the lifting device 3, the elastic telescopic component 7 and the stop block 6 are arranged between the two clamps 4 in sequence. The two connecting screws 12 are passed through the two connecting holes one by one, and the rail 9 is clamped between the two rail clamps 11.

[0041] Finally, nuts are threaded onto both connecting screws 12 for locking, and nuts are threaded onto both fastening screws 8 after passing through the two fastening holes for locking.

[0042] At this time, the lifting device 3 is activated, the lifting device 3 extends, and the elastic telescopic component 7 retracts to transmit pressure to the stop block 6, thereby forming a reaction force on the pressure plate 2, so that the pressure plate 2 and the two rail clamps 11 form a downward pressing force on the rail 9, ensuring that the anti-slip iron shoe is stably installed on the rail 9.

[0043] The electric scooter moves backward, and its pulleys abut against the anti-slip arc surface. The iron shoe body 1 prevents the electric scooter from sliding, and the electric scooter can then be stably parked on the track 9 with a certain slope.

[0044] When this anti-slip track shoe needs to be removed from track 9, first activate the lifting device 3. The lifting device 3 retracts, and the elastic telescopic component 7 extends and resets, releasing the pressure formed on track 9. Then, simply remove the nuts and bolts to quickly detach and remove the anti-slip track shoe from track 9.

[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
