[0031] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0032] like Figures 1 to 4 As shown, the cross-lane bridge system of this utility model embodiment includes a horizontal frame 1 and two inclined frames 2. The width direction of the horizontal frame 1 is defined as the first direction, and the length direction of the horizontal frame 1 is defined as the second direction. The bottom of the horizontal frame 1 is detachably provided with a support rod 3 for supporting the lane floor. The horizontal frame 1 and the support rod 3 restrict a first passage through the first direction. The two inclined frames 2 are symmetrical along the second direction and detachably provided on both sides of the horizontal frame 1. The second direction is set at an angle to the first direction. The top surfaces of the horizontal frame 1 and the two inclined frames 2 restrict a second passage through the second direction.

[0033] In use, the cross-lane bridge system of this utility model first installs support rods 3 at the bottom of the horizontal frame 1 to raise the horizontal frame 1 to a set height, thereby forming a first channel below the horizontal frame 1. The width of the first channel can be adjusted by adjusting the installation position of the support rods 3 to meet different lane requirements. Then, inclined frames 2 are erected on both sides of the horizontal frame 1, forming a second channel on the horizontal frame 1 and the inclined frames 2, thereby realizing synchronous operation at the lane intersection. After use, the bridge system can be disassembled by installing the inclined frames 2 first and then the support rods 3 in sequence, which is convenient and efficient.

[0034] The cross-lane bridge system of this utility model embodiment can realize the detachable assembly of each component, with high installation and disassembly efficiency, greatly shortening the construction cycle, and facilitating the recycling of each component, thus reducing project costs.

[0035] In some embodiments, such as Figures 1 to 5 As shown, the horizontal frame 1 includes multiple unit plates 11 arranged sequentially along the second direction and detachably connected. The two sides of each unit plate 11 are provided with a first connecting part 111 and a second connecting part 112. By setting the horizontal frame 1 as multiple detachably connected unit plates 11, the entire horizontal frame 1 can be disassembled, which facilitates the transportation of the horizontal frame 1. In the process of use, an appropriate number of unit plates 11 can be selected according to the usage requirements, which has a wider range of applications. The connection between two adjacent unit plates 11 is realized through the first connecting part 111 and the second connecting plate, which facilitates modular production, reduces the component processing cost, and increases the connection strength between two adjacent unit plates 11.

[0036] In some embodiments, the first connecting portion 111 of the unit plate 11 is used to cooperate with the second connecting portion 112 of the adjacent unit plate 11. For example, the first unit plate 11 is a slot and the second connecting portion 112 is a plug. Two adjacent unit plates 11 can be directly connected by plugging and connecting.

[0037] In some embodiments, such as Figure 1 , Figure 2 and Figure 3 As shown, the first connecting part 111 of the unit plate 11 is connected to the second connecting part 112 of the adjacent unit plate 11 by a connector 12. For example, the connector 12 is a connecting rod, the first connecting part 111 is a first slot, the second connecting part 112 is a second slot, and the two ends of the connecting rod are used to be inserted into the first slot and the second slot respectively.

[0038] The first connecting part 111 and the second connecting part 112 are connected by the connector 12. Compared with the direct plug-in fit of the first connecting part 111 and the second connecting part 112, the connector 12 increases the uniformity of force when the first connecting part 111 and the second connecting part 112 are connected to each other, avoids the problem of stress concentration at the connection position between the plug rod and the unit plate 11, and thus increases the connection strength between two adjacent unit plates 11.

[0039] In some embodiments, such as Figure 3 As shown, it includes a first fixing member 13, a first through hole on a first slot, a second through hole on a second slot, and connecting holes on a connecting rod corresponding to the first through hole and the second through hole respectively. The first fixing member 13 is used to cooperate with the first through hole and the connecting hole or to cooperate with the second through hole and the connecting hole.

[0040] When connecting two adjacent unit plates 11, first insert one end of the connecting rod into the first slot. When the connecting hole is aligned with the first through hole, install the first fixing member 13. Then insert the other end of the connecting rod into another unit plate 11. When the second through hole is aligned with the corresponding connecting hole, install another first fixing member 13. This achieves an anti-detachment connection between the connecting member 12 and the two adjacent unit plates 11, ensuring the reliable connection between the two adjacent unit plates 11, and thus ensuring the safety and reliability of the bridge system after installation.

[0041] Optionally, the first fastener 13 is a connecting bolt, which may be threaded with a connecting nut to further ensure the installation reliability of the first fastener 13. For ease of construction, the connecting bolt may not be equipped with a connecting nut.

[0042] In some embodiments, such as Figure 1 and Figure 2 As shown, the system includes a guardrail 4, a unit plate 11 with multiple third connecting parts 14, a fourth connecting part 41 on the guardrail 4, and the fourth connecting part 41 is detachably connected to the third connecting parts 14.

[0043] Specifically, the third connecting part 14 is a slide rail extending along the second direction. The slide rail is correspondingly provided on both sides of the unit plate 11. The cross-section of the slide rail is L-shaped or T-shaped. The fourth connecting part 41 is a slide bar. The slide bar is provided with a slide groove that matches the size of the slide rail. Before assembling the unit plate 11, the slide bar can be slidably installed on the slide rail to realize the assembly of the guardrail 4 and the unit plate 11. The operation is convenient and ensures the reliability of the connection between the guardrail 4 and the unit plate 11.

[0044] In some embodiments, such as Figure 1 and Figure 4As shown, the length of the support rod 3 is adjustable. Specifically, the support rod 3 includes a first pipe section 31 and a second pipe section 32 that are inserted into each other. The first pipe section has multiple third through holes 311 spaced apart, and the second pipe section 32 has multiple fourth through holes 321 corresponding to the third through holes 311. Fixing bolts 33 are inserted into both the third through holes 311 and the fourth through holes 321. By adjusting the insertion size between the first pipe section 31 and the second pipe section 32, the corresponding third through holes 311 and fourth through holes 321 can be selected. When the selected third through holes 311 and fourth through holes 321 are aligned, the length of the support rod 3 can be adjusted by the fixing bolts 33. The adjustment is convenient. By adjusting the length of the support rod 3, the setting height of the horizontal frame 1 can be adjusted to meet the requirements of different tunnel construction, thereby realizing the effective adjustment of the passage height of the first and second passages and improving the applicability of the bridge crossing system.

[0045] In some embodiments, such as Figure 1 and Figure 5 As shown, the inclined frame 2 is rotatably connected to the horizontal frame 1. The end of the horizontal frame 1 is provided with a fifth connecting part 15, and the inclined frame 2 is provided with a sixth connecting part 21. A second fixing member 5 passes through the fifth connecting part 15 and the sixth connecting part 21, and the inclined frame 2 is rotatably connected to the second fixing member 5.

[0046] Specifically, the fifth connecting part 15 is the first sleeve, which is fixedly connected to the end of the horizontal frame 1, that is, to one side of the unit plate 11 at the end. The sixth connecting part 21 is the second sleeve, which is fixedly connected to the end of the inclined frame 2. The second fixing member 5 is a rotating shaft, which is used to pass through the first sleeve and the second sleeve at the same time, and the rotating shaft is adapted to the size of the first sleeve and the second sleeve.

[0047] Optionally, at least two first sleeves are provided at intervals along the first direction at the end of the horizontal frame 1, and at least two second sleeves are provided at the end of the inclined frame 2, with the rotating shaft passing through at least two first sleeves and at least two second sleeves located on the same side of the end of the horizontal frame 1.

[0048] Optionally, anti-loosening bolts can be detached at both ends of the shaft.

[0049] In some embodiments, such as Figure 1 and Figure 5 As shown, a diagonal brace 6 is detachably provided between the support rod 3 and the diagonal frame 2. The two ends of the diagonal brace 6 are rotatably connected to the support rod 3 and the diagonal frame 2 respectively, and the length of the diagonal brace 6 is adjustable.

[0050] Specifically, the support rod 3 is provided with a first connecting lug 34, and the inclined frame 2 is provided with a corresponding second connecting lug 22. The inclined brace 6 includes a first rod segment 61 at both ends, a second rod segment 62 between the two first rod segments 61, an adjusting tube 63, and a third rod segment 64. The two first rod segments 61 are used to respectively insert and fit into the first connecting lug 34 and the second connecting lug 22. The adjusting tube 63 is threadedly connected to the second rod segment 62 and the third rod segment 64. The second rod segment 62 and the third rod segment 64 are provided with two threaded sections with opposite directions of rotation. By rotating the adjusting tube 63, the two second rod segments 62 and the third rod segment 64 can be driven to move towards or away from each other. The inclined brace 6 can increase the connection strength between the support rod 3 and the inclined frame 2, thereby increasing the connection reliability and stability of the bridge system. At the same time, the length of the inclined brace 6 is adjustable to match the adjustable length of the support rod 3, realizing the effective adjustment of the passage height of the first and second channels, and improving the applicability of the bridge system.

[0051] In some embodiments, such as Figure 1 , Figure 3 and Figure 4 As shown, the bottom of the horizontal frame 1 is provided with a connecting pipe 16, and the support rod 3 is inserted into the connecting pipe 16. A third fixing member 17 for passing through the support rod 3 is detachably provided on the connecting pipe 16. Specifically, the bottom of each unit plate 11 is provided with four connecting pipes 16. The corresponding connecting pipe 16 can be selected according to the usage requirements for the installation of the support rod 3. At the same time, the third fixing member 17 is provided, and the end of the support rod 3 is inserted into the connecting pipe 16. The third fixing member 17 can prevent the support rod 3 from detaching from the connecting pipe 16, thereby ensuring the reliability of the connection between the support rod 3 and the horizontal frame 1.

[0052] Optionally, the third fastener 17 is a positioning bolt.

[0053] In some embodiments, such as Figure 1 and Figure 4 As shown, the bottom of the support rod 3 is provided with a base plate 7, and the base plate 7 is provided with multiple fixing holes 71. The fixing holes 71 are used to pass through the anchor bolts anchored to the roadway floor. By setting the base plate 7, the pressure at the contact point between the support rod 3 and the roadway floor can be reduced, and the support rod 3 can be prevented from settling relative to the roadway floor under pressure. At the same time, the fixing holes 71 on the base plate 7 can increase the connection between the bridge system and the roadway floor by passing through the anchor bolts, and ensure the stability and reliability of the bridge system during use.
