Description

Technical Field

[0001] The invention relates to the field of prestressed construction, and in particular to an anti-skid and anti-stuck tire multi-directional displacement comb plate telescopic device. Background Art

[0002] At present, among the existing bridge expansion devices, the comb plate expansion devices on the market currently have comb plates that span the expansion joints, and the comb teeth are interlaced and arranged, so that the upper surface of the entire expansion device forms a continuous plane, and vehicles pass smoothly with low noise, which is widely used in bridge engineering. However, due to the setting of the comb teeth, there are some safety risks, such as the longitudinal gap between the comb teeth, and the gap width is relatively large, between 30mm and 100mm. When non-motor vehicles pass, due to the small cross-sectional width of the non-motor vehicle tires, it is easy for the wheels to get stuck in the gap between the tooth plates, causing driving safety problems. Summary of the invention

[0003] The purpose of the present invention is to provide an anti-skid and anti-stuck multi-directional displacement comb plate telescopic device, which solves the problem that when a non-motor vehicle passes through the comb plate telescopic device, the wheel is easily stuck in the tooth plate gap, causing driving safety.

[0004] A skid and tire-proof multi-directional displacement comb tooth plate telescopic device comprises: two relatively arranged comb tooth plates, the comb tooth plates are provided with a plurality of comb tooth bars arranged at intervals, a comb tooth gap is formed between the two comb tooth bars, the comb tooth bars comprise a fixed rack and a wavy rack, the tooth root of the fixed rack is mounted on the comb tooth plate, the tooth root of the wavy rack is butted against the tooth tip of the fixed rack, the comb tooth bars on the two comb tooth plates are inserted into each other's comb tooth gaps, and the tooth tip of the wavy rack is butted against the root of the corresponding comb tooth gap.

[0005] In one embodiment, the tooth root of the wavy rack is installed on the fixed rack, and the tooth tip of the wavy rack is installed on the root of the corresponding comb tooth gap.

[0006] In one embodiment, the tooth root of the wavy rack is provided with a first mounting hole and a first fastener, and the first fastener passes through the first mounting hole to mount the tooth root of the wavy rack to the fixed rack; the tooth tip of the wavy rack is provided with a second mounting hole and a second fastener, and the second fastener passes through the second mounting hole to mount the tooth tip of the wavy rack to the root of the comb tooth gap into which it is inserted.

[0007] In one of the embodiments, the wavy rack is provided with a sliding rod, and the side of the fixed rack is provided with a sliding groove, and the end of the sliding rod extends from the side of the wavy rack and is slidably inserted into the sliding groove.

[0008] In one of the embodiments, the wavy rack is provided with a through hole running through it, and the sliding rod is passed through the through hole and exposed at two sides of the wavy rack.

[0009] In one embodiment, the sliding rod is located below the wavy rack.

[0010] In one embodiment, the sliding rod is located below the crest of the wavy rack.

[0011] In one embodiment, the fixed rack is substantially rectangular in shape, and the wavy rack is substantially rectangular in shape.

[0012] In one of the embodiments, the comb plate is also provided with a multi-directional displacement component, which includes an anchoring frame, an elastic block, and an anchoring bolt. The elastic block is arranged in the anchoring frame, and the elastic block is provided with an installation through hole. The anchoring bolt passes through the installation through hole to lock the comb plate.

[0013] In one of the embodiments, the upper surface of the comb plate and the upper surface of the fixed rack are provided with anti-slip grooves or coated with an anti-slip coating.

[0014] Compared with the prior art, the anti-skid and anti-stuck tire multi-directional displacement comb plate telescopic device of the present invention has the following advantages:

[0015] 1. A plate-type telescopic rack is set in the longitudinal gap of the comb teeth to basically cover the gap of the comb teeth to ensure that the wheels of non-motor vehicles will not get stuck in the gap of the tooth plate when passing through, and at the same time prevent ballast, garbage, etc. from falling into the gap and affecting the extension and retraction of the tooth plate.

[0016] 2. A sliding rod is provided to provide strong support for the wave rack to prevent it from being crushed and deformed, and the sliding rod of the present invention will not affect the extension and retraction of the wave rack.

[0017] 3. It is equipped with a multi-directional displacement component, through which the comb plate is flexibly anchored to the roadbed to achieve vertical, horizontal, oblique and other multi-directional rotations, solving the problem that the movable tooth plate of the existing telescopic device is easily loosened or broken by the rigid anchoring of the bridge with bolts, resulting in the failure of the telescopic device.

[0018] 4. The surface width of the tooth plate of the traditional telescopic device is large. When designing, it is mostly considered that the performance of motor vehicles and motor vehicles pass quickly. Motor vehicles with more than four wheels are usually more stable, but for non-motor vehicles, their tires are narrow and the tread is shallow, which is easy to slip and slide when passing. Especially in rainy and humid weather, once the vehicle slips and slides, it affects driving safety and may cause traffic accidents. The present invention processes anti-skid patterns or sprays anti-skid coatings on the upper surface of the tooth plate of the telescopic device to increase friction and prevent vehicles from slipping and sliding when passing through the bridge telescopic device, so as to achieve the purpose of safe passage of vehicles through the telescopic device.

[0032] A skid and tire-proof multi-directional displacement telescopic device comprises: two comb tooth plates 10 arranged opposite to each other, the comb tooth plates 10 are provided with a plurality of comb tooth bars 11 arranged at intervals, a comb tooth gap 14 is formed between the two comb tooth bars 11, the comb tooth bars 11 comprise a fixed rack bar 12 and a plate-type telescopic rack bar 13, the tooth root of the fixed rack bar 12 is mounted on the comb tooth plates 10, and the tooth root of the plate-type telescopic rack bar 13 is butted against the tip of the fixed rack bar 12; the comb tooth bars 11 on the two comb tooth plates 10 are inserted into each other's comb tooth gaps 14, and the tip of the plate-type telescopic rack bar 13 is butted against the root of the corresponding comb tooth gap 14. The plate-type telescopic rack 13 can be retracted or extended. Regardless of the retracted state or the extended flat state, the plate-type telescopic rack 13 basically covers the gap between the tooth tip of the fixed rack 12 and the root of the comb tooth gap 14, ensuring that non-motor vehicles can pass smoothly, and the wheels will not get stuck in the comb tooth gap 14, while preventing ballast, garbage, etc. from falling into the comb tooth gap 14 and affecting the extension and contraction of the comb tooth plate 10. Preferably, the comb tooth plate 10 can also be provided with or without a support plate. When the support plate is provided, the support plate is located below the comb tooth gap 14, and the plate-type telescopic rack 13 is placed on the support plate. The support plate can provide support for the plate-type telescopic rack 13 to prevent the plate-type telescopic rack 13 from deforming and becoming concave when being crushed by the wheels of non-motor vehicles.

[0033] In this embodiment, Figure 1-7As shown, the plate-type telescopic rack 13 is a wavy rack 15. An anti-skid and anti-stuck tire multi-directional displacement telescopic device comprises two comb plates 10 arranged opposite to each other, the comb plates 10 are provided with a plurality of comb teeth 11 arranged at intervals, a comb tooth gap 14 is formed between the two comb teeth 11, the comb teeth 11 comprises a fixed rack 12 and a wavy rack 15, the tooth root of the fixed rack 12 is mounted on the comb plate 10, and the tooth root of the wavy rack 15 is butted against the tip of the fixed rack 12; the comb teeth 11 on the two comb plates 10 are mutually inserted into each other's comb tooth gap 14, and the tip of the wavy rack 15 is butted against the root of the corresponding comb tooth gap 14.

[0034] like Figure 2 , 3 As shown, the tooth root of the wavy rack 15 is installed on the fixed rack 12, and the tip of the wavy rack 15 is installed on the root of the corresponding comb tooth gap 14. The tooth root of the wavy rack 15 is provided with a first mounting hole 17 and a first fastener 18, and the first fastener 18 passes through the first mounting hole 17 to mount the tooth root of the wavy rack 15 on the fixed rack 12; the tip of the wavy rack 15 is provided with a second mounting hole 19 and a second fastener 20, and the second fastener 20 passes through the second mounting hole 19 to mount the tip of the wavy rack 15 on the root of the comb tooth gap 14 into which it is inserted. By utilizing the undulating shape of the wavy rack 15 itself, the first mounting hole 17 and the second mounting hole 19 are provided at the tooth root of the wavy rack 15, and the tooth root and tooth tip of the wavy rack 15 can be conveniently installed and fixed by using the first fastener 18 and the second fastener 20. The first fastener 18 and the second fastener 20 are bolts or screws. In this embodiment, both ends of the wavy rack 15 are fixedly mounted, and when the two comb plates 10 move relative to each other, the wavy rack 15 is ensured to cover the comb tooth gap 14. However, it is not limited to this embodiment, and the wavy rack 15 can also cover the comb tooth gap 14 by utilizing its own resilience, or a spring or other resilient member can be provided on the wavy rack 15 to make the wavy rack 15 have resilient properties.

[0035] The wavy rack 15 is provided with a sliding rod 21, and a sliding groove 22 is provided on the side of the fixed rack 12. The end of the sliding rod 21 extends from the side of the wavy rack 15 and is slidably inserted into the sliding groove 22. In this embodiment, the sliding rod 21 is inserted into the sliding groove 22 to provide support for the wavy rack 15. Even if a support plate is not provided, the non-motor vehicle tire can be well supported to prevent the tire from being stuck. In addition, the provision of the sliding rod 21 will not interfere with the extension and retraction of the wavy rack 15. However, it is not limited to this embodiment, and a support plate can also be provided. The support plate is located below the comb tooth gap 14, and the wavy rack 15 is placed on the support plate. The support plate can provide support for the wavy rack 15 to prevent the wavy rack 15 from deforming and becoming concave when being crushed by the wheels of non-motor vehicles.

[0036] Preferably, the wavy rack 15 is provided with a through hole 26 running through it, and the sliding rod 21 is passed through the through hole 26. The installation method of the sliding rod 21 passing through the through hole 26 is convenient for installation, and it is convenient for the wavy rack 15 to drive the sliding rod 21 to slide along the sliding groove 22 when the wavy rack 15 is extended or retracted. Preferably, the two ends of the sliding rod 21 are exposed from both sides of the wavy rack 15 and inserted into the sliding grooves 22 on both sides respectively. Preferably, the through hole 26 is located at the middle position of the height between the crest and the trough of the wavy rack 15, so that the sliding rod 21 can be evenly distributed in the comb tooth gap 14 occupied by the wavy rack 15, ensuring that non-motor vehicles pass smoothly and the wheels will not get stuck in the tooth plate gap. At the same time, it prevents ballast, garbage, etc. from falling into the gap and affecting the extension and retraction of the comb plate 10; and, even if ballast falls into the wavy rack 15, since the wavy rack 15 is hung on the sliding groove 22 through the sliding rod 21, it is difficult for the ballast to fall into the sliding groove. In addition, the ductility of the wavy rack 15 itself can accommodate a certain amount of ballast, and will not affect the overall function of the telescopic device. Moreover, the ballast that falls in will be vibrated and thrown out after being crushed by the vehicle many times due to the ductility of the wavy rack 15 itself, and the cleaning will be restored.

[0037] Not limited to the above Figure 2 The embodiment shown can also be designed as follows: Figure 4 As shown, the sliding rod 21 is located under the wavy rack 15. The sliding rod 21 and the wavy rack 15 are separate and independent. The sliding rod 21 is located below the crest of the wavy rack 15 and in the middle between the crest and the trough. The sliding rod 21 crosses the wavy rack 15 and is exposed from both sides of the wavy rack 15. Both ends of the sliding rod 21 are slidably inserted into the sliding groove 22. When the wavy rack 15 is extended or retracted, the sliding rod 21 can be driven to slide along the sliding groove 22, so that the sliding rod 21 is evenly distributed in the comb tooth gap 14 occupied by the wavy rack 15, ensuring that non-motor vehicles pass smoothly and the wheels will not get stuck in the tooth plate gap.

[0038] In this embodiment, the plate-type telescopic rack 13 is a wavy rack 15. A wavy rack refers to a rack that is provided with folds and can be extended and retracted, including but not limited to arc wave shapes, sawtooth shapes, or other equivalent shapes, as long as the functions created by the present invention can be completed. The wavy rack 15 can be soft or hard. In this embodiment, the wavy rack 15 is integrally formed of rubber or polymer materials, and the wavy shape has certain flexibility, ductility, and resilience, and can be pulled open or folded. However, it is not limited to this embodiment, and can also be designed as follows, Figure 5 As shown, the wavy rack 15 is not integrally formed, and the wavy rack 15 includes a plurality of chain plates 27 hinged at the head and tail by a pin 28. The chain plates 27 can be made of rubber, polymer material, or metal sheet. When the plurality of chain plates 27 are compressed and shortened, they present a sawtooth wave shape. Both sides of the chain plates 27 are slidably inserted into the sliding groove 22, and the sliding groove 22 directly supports the wavy rack 15 from both sides.

[0039] Not limited to the above-mentioned implementation mode, it can also be designed as follows: Figure 6 , 7 As shown, the plate-type telescopic rack 13 includes a plurality of movable tooth pieces 23, which are stacked when retracted and laid flat when extended. The side of the fixed rack 12 is provided with a sliding groove 22, and both sides of the movable tooth piece 23 are slidably inserted into the sliding groove 22. The sliding rod 21 can be set or not, such as Figure 6 , 7 As shown, it is an embodiment without the sliding rod 21, the root of the movable tooth piece 23 is provided with a first hook portion 24, and the tip of the movable tooth piece 23 is provided with a second hook portion 25. When the plate-type telescopic rack 13 is extended, the second hook portion 25 of the front movable tooth piece 23 and the first hook portion 24 of the rear movable tooth piece 23 are hooked with each other. By setting the second hook portion 25 and the first hook portion 24 to hook with each other, it can be ensured that the movable tooth piece 23 covers the comb tooth gap 14 occupied by the plate-type telescopic rack 13 when extended.

[0040] The comb plate 10 is also provided with a multi-directional displacement assembly 30, which includes an anchoring frame 31, an elastic block 32, and an anchoring bolt 33. The elastic block 32 is arranged in the anchoring frame 31, and the elastic block 32 is provided with a mounting through hole 34. The anchoring bolt 33 passes through the mounting through hole 34 and the anchoring frame 31 to lock the comb plate 10. The anchoring frame 31 is installed on the roadbed, and the comb plate 10 is elastically anchored on the roadbed through the multi-directional displacement assembly 30. When the comb plate 10 is subjected to repeated impacts of wheel loads and multi-directional displacements such as vertical, horizontal, and oblique at the end, the elastic block 32 is compressed and sheared by the anchoring bolt 33 to rotate vertically, horizontally, obliquely, and other multi-directionally, and the elastic block 32 automatically rebounds and recovers after the external force disappears. The problem that the rigid anchoring of the bolt is easy to loosen and break, resulting in the failure of the telescopic device is solved.

[0041] A water collecting trough 40 is provided below the plate-type telescopic rack 13. The water collecting trough 40 is used to divert the accumulated water. The water collecting trough 40 is U-shaped, and the two sides of the water collecting trough 40 are installed on the roadbed by bolts. Figure 2 As shown, the upper surface of the comb plate 10 and the upper surface of the fixed rack 12 are provided with anti-skid grooves or coated with an anti-skid coating 50 to increase friction and prevent vehicles, especially non-motor vehicles, from slipping or sliding sideways when passing through the bridge telescopic device.

[0042] The present invention has been described above in conjunction with the best embodiments, but the present invention is not limited to the embodiments disclosed above, but should cover various modifications and equivalent combinations based on the essence of the present invention.
