Description

Technical Field

[0001] This invention relates to the field of cable trench cover technology, and in particular to a bridge-type cable trench cover anti-rollover device. Background Technology

[0002] In the construction and maintenance of power and telecommunications facilities, cable trenches, as important underground pipeline structures, bear the crucial task of laying and replacing power or telecommunications cables. The enclosure structures of cable trenches, including rectangular, circular, and arched forms, not only ensure the safe and stable operation of cable facilities but also provide necessary support for urban construction and power engineering.

[0003] However, in actual use, cable trench covers, as the final components used in the laying of cable trenches, often face the problem of vehicle passage. Traditional cable trench cover designs often do not take into account the impact of vehicles running over them, leading to two common phenomena: first, vehicles directly run over the cable trench covers, causing damage and affecting the safety of cable facilities; second, vehicles choose to take detours to avoid running over the cable trench covers, which not only increases travel distance but may also lead to traffic congestion and safety hazards.

[0004] To address this issue, existing cable trench cover anti-rollover devices with arched structures are mostly fixed and placed at the top of the cable trench to allow vehicles to pass. However, during vehicle travel, the squeezing force can easily cause the non-fixed anti-rollover device to move, resulting in poor performance. Furthermore, cable trenches vary in diameter and height, and the anti-rollover device cannot be adjusted according to the actual situation, thus limiting its practicality. Summary of the Invention

[0042] Example 1

[0043] Reference Figures 1-5 and Figures 10-11 This is the first embodiment of the present invention. This embodiment provides a bridge-type cable trench cover anti-crushing device, including the design of the adjustment component 100, which provides a safe and flexible bridge solution for cable trenches on grass, ensuring the safety of cables and facilitating vehicle passage.

[0044] Specifically, the adjustment component 100 includes a grass body 101, a cable trench body 102 disposed on the side wall of the grass body 101 for installing cables, and an adjustment element 103 for adjusting height is installed on the top of the grass body 101 and the cable trench body 102.

[0045] Furthermore, the adjusting component 103 includes a bridge-type cover plate 103a disposed at the top of the grass body 101. A jack 103b is mounted at the bottom end of the bridge-type cover plate 103a, and a spike 103c is mounted at the bottom end of the jack 103b. A level 103d is mounted on the side wall of the bridge-type cover plate 103a, and a slope plate 103j is hinged to the end of the bridge-type cover plate 103a. First, the bridge-type cover plate 103a is installed at the top of the grass body 101, covering the cable trench body 102. The jack 103b is installed at the bottom end of the bridge-type cover plate 103a, and the spike 103c is mounted at the bottom end of the jack 103b. The spike 103c is used to insert into the grass body 101 to provide stability. The level 103d is mounted on the side wall of the bridge-type cover plate 103a to ensure the flatness of the bridge-type cover plate 103a during installation and adjustment.

[0046] Furthermore, the adjusting component 103 also includes a movable rod 103e disposed inside the spike 103c. A limiting plate 103f is installed at the top of the movable rod 103e, a fixing plate 103i is installed on the side wall of the movable rod 103e, a movable plate 103g is installed at the bottom of the fixing plate 103i, and barbs 103h are hinged to the side walls of the fixing plate 103i and the movable plate 103g.

[0047] Operation Process: A ramp plate 103j is hinged to the end of the bridge-type cover plate 103a to form a slope when the bridge-type cover plate 103a is raised, facilitating vehicle access. When the height of the bridge-type cover plate 103a needs to be adjusted, the jack 103b is activated. The jack 103b will push the bridge-type cover plate 103a up or down to accommodate vehicles of different heights. During the raising and lowering process, the ramp plate 103j will deflect accordingly to maintain a proper slope. The spike 103c is inserted into the grass body 101 to provide initial stability for the bridge-type cover plate 103a. A moving rod 103e is provided inside the spike 103c, and a limiting plate 103f is installed at the top of the moving rod 103e. By adjusting the limiting plate 103f, the spike 103c can be inserted deeper into the grass, improving stability. The moving rod 103e has a fixed plate 103i and a moving plate 103g mounted on its side wall, which are hinged together by barbs 103h. When the moving rod 103e and barbs 103c move downward, the barbs 103h unfold and insert into the grass, further increasing stability and preventing the bridge cover 103a from slipping. A level 103d is used to monitor the flatness of the bridge cover 103a during installation and adjustment. By adjusting the positions of the jacks 103b and barbs 103c, it can be ensured that the bridge cover 103a remains level at any height. When a vehicle needs to pass over the cable trench body 102, the vehicle can smoothly drive up the bridge cover 103a along the ramp 103j and then safely cross the cable trench.

[0048] Example 2

[0049] Reference Figures 3-6 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that the fixing component 200 can effectively ensure the stable installation and fixed position of the adjusting component 103 on the grass body 101, providing a safe passage for vehicles to cross the bridge.

[0050] Specifically, the fixing component 200 includes a mounting plate 201 disposed at the bottom end of the adjusting member 103. A limiting member 202 for restricting the movement of the adjusting member 103 is mounted at the bottom end of the mounting plate 201. A retaining member 203 for fixing the adjusting member 103 is mounted on the side wall of the limiting member 202. The fixing component 200 is mounted on the bottom end of the adjusting member 103 via the mounting plate 201. The mounting plate 201 has three sets of slots 202b inside, which are used to receive a plug rod 202a. The plug rod 202a is fixed to the top end of the jack 103b for connecting the adjusting member 103 to the fixing component 200.

[0051] Furthermore, the limiting member 202 includes a rod 202a disposed at the top of the jack 103b. Three sets of slots 202b are installed inside the mounting plate 201, and two sets of insert blocks 202c are installed inside each slot 202b. Each set of insert blocks is located on both sides of the slot. When the rod 202a is inserted into the slot 202b, the sidewall of the rod 202a interacts with the insert block 202c. A first telescopic spring 202d is provided on the sidewall of the insert block 202c. When the rod 202a is inserted into the slot 202b, the rod 202a will press the insert block 202c to move to both sides, compressing the first telescopic spring 202d. When the insertion rod 202a moves to the appropriate position, the first telescopic spring 202d returns to its original state, pushing the insertion block 202c to move inward into the insertion rod 202a, thereby restricting the movement of the insertion rod 202a and ensuring the stable position of the adjusting member 103. The top of the insertion rod 202a and the top of the slot 202b are both semi-circular. This design makes the insertion and removal of the insertion rod smoother and reduces the possibility of friction and damage. The retaining member 203 is installed on the side wall of the limiting member 202 to further fix the position of the adjusting member 103.

[0052] Furthermore, the limiting member 202 also includes a first telescopic spring 202d disposed on the side wall of the insert block 202c. The insert block 202c is inserted into the slot on the side wall of the insert rod 202a. The top end of the insert rod 202a contacts the buffer airbag 202e. Both the top end of the insert rod 202a and the top end inside the slot 202b are semi-circular. The top end of the insert rod 202a contacts the buffer airbag 202e. The buffer airbag 202e provides cushioning when the vehicle passes over the adjusting member 103 and is subjected to other external forces, reducing impact and vibration, while allowing the adjusting member 103 a certain amount of movement space to adapt to different situations.

[0053] The rest of the structure is the same as in Example 1.

[0054] Operating Procedure: Prepare the fixing assembly 200, ensuring that the mounting plate 201, limiting member 202, and retaining member 203 are all in good working order. Inspect the lawn body 101, determine the installation position, and prepare the necessary tools. Place the adjusting member 103 in the predetermined position on the lawn body 101. Install the mounting plate 201 of the fixing assembly 200 onto the bottom end of the adjusting member 103, ensuring a secure installation. Then align the insertion rod 202a at the top of the jack 103b with the three sets of slots 202b inside the mounting plate 201. Gently insert the insertion rod 202a into the slot 202b, noting the semi-circular design of the tip of the insertion rod 202a and the inner top of the slot 202b to ensure smooth insertion. When the insertion rod 202a is inserted into the slot 202b, the side wall of the insertion rod 202a interacts with the insertion block 202c, squeezing the insertion block 202c to move to both sides, while simultaneously compressing the first telescopic spring 202d. Once the insert rod 202a is moved to the appropriate position, the first telescopic spring 202d returns to its original state, pushing the insert block 202c to move inwards towards the insert rod 202a, thereby limiting the movement of the insert rod 202a and ensuring the stable position of the adjusting member 103. The buffer airbag 202e is installed at the top of the insert rod 202a, ensuring tight contact. The buffer airbag 202e provides cushioning when the vehicle passes over the adjusting member 103 and is subjected to other external forces, reducing impact and vibration. A retaining member 203 is installed on the side wall of the limiting member 202 to further fix the position of the adjusting member 103 and enhance stability. A level 103d is used to adjust the flatness of the entire bridge cover 103a to ensure smooth vehicle operation. The stability and cushioning effect of the adjusting member 103 are tested to ensure it meets the usage requirements. After confirming that all components are installed correctly, the adjusting member 103 is stable, and meets the usage requirements, the installation is complete.

[0055] Example 3

[0056] Reference Figures 4-9 This is the third embodiment of the present invention. The difference between this embodiment and the previous embodiments is that when the position of the adjusting member 103 is adjusted, the various components of the holding member 203 will work together to ensure its stability and safety.

[0057] Specifically, the retaining member 203 includes a connecting rod 203a disposed inside the mounting plate 201. The side wall of the connecting rod 203a is connected to one set of insert blocks 202c. A push rod 203b is installed on the side wall of one set of insert blocks 202c. One end of the push rod 203b extends to the outside through another set of insert blocks 202c. The insert rod 202a is inserted into the slot 202b and is limited by the insert block 202c under the action of the first telescopic spring 202d, ensuring that the insert rod 202a is stable and does not move. The connecting rod 203a is in the initial position, and the second telescopic spring 203f is not compressed. The deflection rod 203d is hinged to the mounting plate 201 through the hinge rod 203e, maintaining its free state.

[0058] Furthermore, the retaining member 203 also includes a sliding block 203c disposed inside the mounting plate 201. A deflection rod 203d is hinged to the side wall of the sliding block 203c, and the side wall of the deflection rod 203d is hinged to the mounting plate 201 through a hinge rod 203e.

[0059] Furthermore, the retaining member 203 also includes a second telescopic spring 203f disposed on the side wall of the connecting rod 203a, the side wall of the connecting rod 203a is provided with a handle 203g for pulling and fixing, and the end side wall of the connecting rod 203a is provided with threads.

[0060] Furthermore, the retaining member 203 also includes an arc plate 203h disposed on the side wall of the bridge cover plate 103a, the end of the connecting rod 203a extends into the interior of the bridge cover plate 103a, and a telescopic ring 203i is disposed inside the arc plate 203h. A wedge block 203n is threadedly connected to the end of the arc plate 203h, and a threaded cylinder 203j that matches the thread of the side wall of the connecting rod 203a is installed at the end of the wedge block 203n.

[0061] Furthermore, the retaining member 203 also includes a sliding groove 203k disposed on the inner wall of the arc plate 203h, a sliding rod 203l installed inside the sliding groove 203k, a telescopic rod 203m installed inside the sliding rod 203l, the telescopic rod 203m being connected to the sliding groove 203k, a clamping plate 203p being installed at the end of the sliding rod 203l, and a connecting rod 203q being disposed inside the arc plate 203h.

[0062] The rest of the structure is the same as in Example 2.

[0063] Operating Procedure: When a vehicle needs to pass over the cable trench body 102, first install the anti-rollover device. First, connect the jack 103b to the bridge cover 103a. Then, insert the rod 202a into the slot 202b. The insertion force then pushes the insert block 202c to move to both sides. When the rod 202a reaches the appropriate position, the first tension spring 202d, which stores energy, drives the insert block 202c to insert into the rod 202a, limiting its position. After connection, insert the spike 103c into the grass body 101. Then, adjust the flatness of the entire bridge cover 103a according to the level 103d. When adjusting the flatness, the limiting plate 103f is struck with a hammer. The limiting plate 103f causes the spikes 103c to move downwards, which in turn moves the moving plate 103g. The downward movement of the moving plate 103g causes the barbs 103h to deflect and unfold, inserting into the grass body 101, improving stability and preventing detachment. Then, the jack 103b is activated, causing the bridge cover 103a to move upwards. During this upward movement, the slope plate 103j deflects, causing the connecting rod 203q to slide inside the curved plate 203h. After the height adjustment is complete, hold the handle 203g and pull the connecting rod 203a to move one of the inserts 202c, which in turn moves the push rod 203b through the other insert 202c to press against the sliding block 203c. The moving sliding block 203c can effectively drive the deflection rod 203d to offset and press against one of the inserts 202c, thereby preventing the insert rod 202a from dislodging from the slot 202b due to external forces. When the vehicle travels over the bridge cover 103a, the buffer airbag 202e provides space for movement, improving the stability of the connection. Then, rotate the wedge block 203n, and the inclined surface of the wedge block 203n will move the telescopic ring 203i. The compression causes it to expand, and the expanded telescopic ring 203i will drive the sliding rod 203l to move and store force on the telescopic rod 203m. The moving sliding rod 203l will drive the clamping plate 203p to limit the connecting rod 203q, thereby fixing the deflection rod 203d. The inwardly moving threaded cylinder 203j will be threadedly connected to the connecting rod 203a. The inner wall of the wedge block 203n that compresses the telescopic ring 203i is threadedly connected to the arc plate 203h. After fixing, the vehicle will press down on the slope plate 103j when it drives over it. Since the bottom end of the slope plate 103j is provided with protrusions, the firmness of the slope plate 103j can be effectively improved.
