Description

Technical Field

[0001] This invention relates to the field of municipal cable laying technology, and in particular to a device for burying cross-street cables. Background Technology

[0002] With the increasing number of scenarios such as urbanization, engineering construction, and emergency rescue, the demand for laying cables (power cables, communication cables, monitoring cables, etc.) across streets is becoming more and more frequent. The core requirement is to avoid damage to cables caused by vehicle running over them, rainwater erosion, external displacement, etc., while ensuring the normal transmission function of the cables. At the same time, it is also necessary to take into account the ease of installation, reusability, and adaptability to different scenarios.

[0003] The current mainstream solution in the industry for cable crossing protection is: Ordinary plastic cable trough speed bumps are made of general-purpose plastic materials. The trough structure is simple, with symmetrical guide slopes on both sides. They can be fixed with bolts or laid directly on the ground. They support modular splicing of the basic structure and are mainly used for temporary or short-distance cable crossing protection. Their core advantages are lightweight and easy handling. Simple conduit protection involves directly threading the cable through a rubber, plastic, or metal conduit, laying it flat on the ground, and securing it simply. In some scenarios, warning signs will be placed on both sides of the conduit. This solution is suitable for rapid deployment scenarios such as emergency rescue and short-term construction, and is low in cost and easy to operate. While the existing solutions can meet basic cable protection requirements, they present many technical problems that are difficult to solve in practical applications: ordinary plastic cable tray speed bumps and simple sleeve protection both adopt a symmetrical guide slope design. When applied to a one-way lane, vehicles travel in one direction for a long time, and the thrust of the tires on the guide slope is concentrated on one side, causing the protective body to be subjected to a continuous unidirectional forward thrust, which can easily lead to twisting and displacement, and then squeeze the internal cables, causing cable insulation layer damage, core wire breakage and other faults. Summary of the Invention

[0004] In view of this, it is necessary to provide a device for laying cross-street cables that can solve the problems of twisting and displacement.

[0005] This invention provides a device for burying cross-street cables, comprising: The main body has a cable through hole, which extends through the main body along its length. A first inclined portion, the first inclined portion being disposed on one side of the main body portion along its length, the first inclined portion having a first inclined surface tilted towards an oncoming vehicle; and The second inclined portion is located on the other side of the length direction of the main body portion. The first inclined portion has a second inclined surface that is inclined towards the vehicle leaving the vehicle. The first inclined surface and the second inclined surface are asymmetrical so that the force generated by the vehicle driving towards the first inclined surface is balanced with the force generated by the vehicle leaving the second inclined surface.

[0006] In other embodiments, the first inclined plane has an inclination of 5° to 10°, and the length of the first inclined portion is 6 to 8 times its height.

[0007] In other embodiments, the second inclined plane has an inclination of 15° to 20°, and the length of the second inclined portion is 3 to 4 times its height.

[0008] In other embodiments, a plurality of anti-slip grooves are formed on the first inclined surface along the length direction of the main body, and the inner diameter of the anti-slip grooves gradually decreases with the depth of the anti-slip grooves.

[0009] In other embodiments, a plurality of anti-slip protrusions are provided on the second inclined surface along the width direction of the main body, and the surface of the anti-slip protrusions has a rounded transition.

[0010] In other embodiments, an anti-slip underlayer is also included, which is disposed at the bottom of the main body, the first inclined body, and the second inclined body.

[0011] In other embodiments, the anti-slip base layer is made of a soft adhesive material, the thickness of the anti-slip base layer is 3-5mm, and the bottom surface of the anti-slip base layer is provided with a honeycomb anti-slip texture.

[0012] In other embodiments, a locking block is also included. The locking block is disposed on one side of the first inclined portion and the second inclined portion and protrudes relative to the first inclined portion and the second inclined portion. A locking groove matching the locking block is opened on the other side of the first inclined portion and the second inclined portion at the position corresponding to the locking block. The locking block is locked into the locking groove of the adjacent cross-street cable laying device, so that the adjacent cross-street cable laying devices are locked together.

[0013] In other embodiments, a plurality of through-holes for insulating rope are symmetrically provided on both sides of the first inclined portion and the second inclined portion.

[0014] In other embodiments, the first inclined body and the second inclined body are further provided with a plurality of hooks, which are embedded in the second inclined body and the first inclined body through a cross-shaped anchoring structure, and their installation positions coincide with the force centers of the first inclined surface and the second inclined surface.

[0015] The beneficial effects of this invention are as follows: This invention provides a cross-street cable burial device, comprising a main body, a first inclined body, and a second inclined body. The main body has a cable through-hole extending through it along its length. The first inclined body is located on one side of the main body along its length and has a first inclined surface tilted towards oncoming vehicles. The second inclined body is located on the other side of the main body along its length and has a second inclined surface tilted towards departing vehicles. The first and second inclined surfaces are asymmetrical to balance the force exerted by a vehicle moving towards the first inclined surface and the force exerted by a vehicle moving away from the second inclined surface. In this invention, the asymmetrical design of the first inclined surface of the first inclined body and the second inclined surface of the second inclined body balances the forward thrust generated by a vehicle passing over the first inclined surface and the reverse corrective force generated by a vehicle passing over the second inclined surface. This solves the problem of twisting and displacement in cross-street cable burial devices, which can lead to compression of internal cables, resulting in damage to the cable insulation layer and breakage of the core wires. Attached Figure Description

Obviously, the accompanying drawings described below are only some embodiments of the present invention. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

Detailed Implementation

[0018] Preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which form part of this application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not intended to limit the scope of the present invention.

[0019] like Figure 1As shown, an embodiment of the present invention provides a cross-street cable laying device, which includes: a main body 1, a first inclined body 2, and a second inclined body 3. The main body 1 has a cable through hole 11, which passes through the main body 1 along its length direction. The first inclined body 2 is located on one side of the main body 1 along its length direction and has a first inclined surface 21 inclined towards oncoming vehicles. The second inclined body 3 is located on the other side of the main body 1 along its length direction and has a second inclined surface 31 inclined towards departing vehicles. The first inclined surface 21 and the second inclined surface 31 are asymmetrical so that the force generated by the vehicle moving towards the first inclined surface 21 is balanced with the force generated by the vehicle moving away from the second inclined surface 31.

[0020] In this invention, the first inclined surface 21 of the first inclined body 2 and the second inclined surface 31 of the second inclined body 3 are designed asymmetrically, so that the "forward thrust" generated by the vehicle passing over the first inclined surface 21 and the "reverse correction force" generated by the vehicle passing over the second inclined surface 31 are dynamically balanced, thereby solving the problem of twisting and displacement of the cross-street cable burial device, which in turn squeezes the internal cable, causing damage to the cable insulation layer and breakage of the core wire.

[0021] Specifically, the main body 1 is rectangular in shape and is integrally formed with the first inclined body 2 and the second inclined body 3. The connection between the main body 1 and the first inclined surface 21 and the second inclined surface 31 is a rounded transition. The purpose of this design is to further disperse the stress concentration during tire rolling by the rounded surface and prevent cracking at the top of the slope.

[0022] In this embodiment, the connection between the main body 1 and the first inclined surface 21 and the second inclined surface 31 is transitioned by an arc with a radius of 15-20mm.

[0023] Specifically, the length of the first inclined section 2 is 6-8 times its height, so that the first inclined surface 21 forms a "long and gentle slope" structure, which increases the transition distance of the vehicle tire from the ground to the upper surface of the protective groove by 30% compared with the prior art, reduces the instantaneous impact load by more than 40%, and helps to extend its service life.

[0024] Specifically, the inclination angle of the first inclined surface 21 is 7°±2°. A plurality of anti-slip grooves are formed on the first inclined surface 21 along the length of the main body 1. The inner diameter of the anti-slip grooves gradually decreases with the depth of the grooves, and the anti-slip grooves are in an inverted V-shape, which enhances the friction between the tire and the slope surface and guides rainwater to the sides to prevent water accumulation on the slope.

[0025] Specifically, the length of the second inclined section 3 is 3-4 times its height, so that the second inclined surface 31 forms a "short steep slope" structure. When the tire drives out, the contact angle between the tire and the second slope is increased by 60% compared with traditional products, and the reverse correction force is increased by 2.5 times. This helps to correct the cross-street cable laying device.

[0026] Specifically, the inclination angle of the second inclined surface 31 is 18°±2°. Several anti-slip protrusions are formed on the second inclined surface 31 along the width direction of the main body 1. The surfaces of these anti-slip protrusions have a rounded transition, allowing them to form an engaging contact with the tire tread pattern, thus enhancing the efficiency of reverse thrust transmission.

[0027] When a vehicle enters, the first inclined plane 21 forms a gentle 7° slope. Through a "long-distance transition + arc transition", the tire impact is converted into uniform vertical pressure, preventing the protective groove from "slipping" due to instantaneous impact. When the vehicle exits, the tire tread engages with the anti-slip ridges of the 18° steep slope of the second inclined plane 31, and the tire applies "slanted downward" pressure to the slope (decomposed into horizontal reverse force and vertical pressure). The magnitude of the horizontal reverse force is positively correlated with the vehicle weight and driving speed, and can offset the forward thrust generated when the vehicle enters in real time. Therefore, when the cross-street cable laying device experiences slight displacement due to long-term use, the repeated crushing by subsequent vehicles will continuously "pull back" the protective groove to its initial position through the reverse correction force, achieving dynamic self-correction and completely eliminating cumulative displacement and twisting.

[0028] Specifically, the cross-street cable laying device also includes an anti-slip underlayer, which is disposed at the bottom of the main body 1, the first inclined body 2, and the second inclined body 3. The anti-slip underlayer is made of a soft adhesive material, has a thickness of 3-5 mm, and has a honeycomb-shaped anti-slip texture on its bottom surface. The anti-slip underlayer adheres to the ground through its own adhesiveness, while the honeycomb structure enhances the friction with the ground to prevent slippage.

[0029] Specifically, the cross-street cable laying device further includes a locking block 4. The locking block 4 is located on one side of the first inclined portion 2 and the second inclined portion 3 and protrudes relative to the first inclined portion 2 and the second inclined portion 3. On the other side of the first inclined portion 2 and the second inclined portion 3, at the position corresponding to the locking block 4, a locking groove 5 matching the locking block 4 is formed. The locking block 4 is engaged into the locking groove 5 of the adjacent cross-street cable laying device, so that the adjacent cross-street cable laying devices are mutually locked. The locking block 4 and the locking groove 5 cooperate with each other, so that multiple cross-street cable laying devices are spliced ​​together to form an "integral force-bearing unit", avoiding displacement of a single cross-street cable laying device that would cause overall misalignment.

[0030] Furthermore, the first inclined body 2 and the second inclined body 3 are symmetrically provided with a number of through insulating rope holes 6 on both sides. Insulating ropes can be inserted into the insulating rope holes 6 to fix the cross-street cable burial device to a preset anchor point on the ground or an adjacent fixed object.

[0031] In addition, to facilitate transportation and installation of the cross-street cable laying device, the first inclined body 2 and the second inclined body 3 are also provided with several hooks 7. These facilitate the engagement and dragging of the hook tool to achieve fine-tuning of the position.

[0032] The hook 7 is embedded in the second inclined body 3 and the first inclined body 2 through a cross-shaped anchoring structure. Its installation position coincides with the force center of the first inclined surface 21 and the second inclined surface 31. When the reverse correction force is applied, the hook 7 can transfer part of the horizontal force to the rope fixing point, forming a synergistic cancellation of "correction force + rope tension", avoiding deformation caused by excessive force on the end of the cross-street cable burial device.

[0033] To demonstrate the technical effectiveness of the asymmetric design of this invention, the following experiments were also conducted: 1. Symmetrical gentle slope group: Both sides are 5° symmetrical gentle slopes (without correction design) to allow vehicles to pass through the cable laying device one after another;

[0034] 2. Symmetrical steep slope group: Both ends are symmetrical steep slopes of 18°, allowing vehicles to pass through the cable laying device one after another;

[0035] 3. Asymmetrical design group: The first slope has an inclination of 5°~10°, and the second slope has an inclination of 15°~20°, allowing vehicles to pass through the cable laying device successively.

[0036] The above experiments show that a smooth-transition approaching slope can eliminate vehicle bumps and reduce initial deviation from the source; while a steep slope with a large inclination angle can use the difference in tire surface friction to generate a unidirectional reverse correction torque to correct driving deviation; and an asymmetrical double-slope structure can control the residual deviation of the vehicle after passing the protective groove to within 2mm, with a correction efficiency of >93%.

[0037] Compared with the prior art, the present invention has the following significant advantages: This invention provides a cross-street cable burial device, comprising a main body, a first inclined body, and a second inclined body. The main body has a cable through-hole extending through it along its length. The first inclined body is located on one side of the main body along its length and has a first inclined surface tilted towards oncoming vehicles. The second inclined body is located on the other side of the main body along its length and has a second inclined surface tilted towards departing vehicles. The first and second inclined surfaces are asymmetrical to balance the force exerted by a vehicle moving towards the first inclined surface and the force exerted by a vehicle moving away from the second inclined surface. In this invention, the asymmetrical design of the first inclined surface of the first inclined body and the second inclined surface of the second inclined body balances the forward thrust generated by a vehicle passing over the first inclined surface and the reverse corrective force generated by a vehicle passing over the second inclined surface. This solves the problem of twisting and displacement in cross-street cable burial devices, which can lead to compression of internal cables, resulting in damage to the cable insulation layer and breakage of the core wires.
