[0002] A traffic gantry is a gantry installed on a traffic road. It serves to limit the height of the vehicle, prompt the driver with information, collect vehicle-related data, and publicize traffic information.

[0003] Currently, the gantries on the market are composed of two side columns and a middle crossbeam structure fixed and welded. Different regions and road conditions have different requirements for the size of the gantries. When the gantries are used in different usage scenarios, manufacturers are required to customize gantries of different sizes according to actual conditions and then transport them to the installation site.

[0004] With regard to the above-mentioned related technologies, the inventors found that the applicable scenarios of the above-mentioned gantries are relatively single, and their adaptability to different usage scenarios is low. In addition, when the road surface needs to be rebuilt or expanded in the later stage of the road project, the above-mentioned gantries are difficult to adjust in size to adapt to the changes in the road surface. It is necessary to dismantle the unmatched gantries and install the matching ones, which is time-consuming and labor-intensive. Summary of the invention

[0023] By adopting the above technical solution, when installing the end cross beams and the middle cross beams, the connecting plates are spliced ​​together so that the first unit tube is inserted into the second annular groove and the second unit tube is inserted into the first annular groove.

[0025] When the first unit plate is completely located in the first unit tube, the control rod is located in the initial position, and when the first unit plate is located in the first unit tube and the second unit tube at the same time, the control rod is located in the locking position.

[0026] By adopting the above technical solution, it is convenient for workers to control the sliding of the first unit plate and the second unit plate through the sliding control rod.

[0027] Optionally, the connecting plate is provided with a sliding groove for the control rod to slide, and inner walls on both sides of the sliding groove are provided with blocks for limiting the control rod to remain in the locked position, and the space between the two sides of the blocks close to each other is the clearance space;

[0028] The control rod comprises a first rod body and a second rod body, the first rod body and the second rod body are rotatably connected, the first rod body is connected to the mounting ring plate, the second rod body comprises a connecting portion and a yielding portion, the connecting portion is rotatably connected to the first rod body, the thickness of the yielding portion is less than the distance between the two sides of the stoppers that are close to each other, the width of the yielding portion is greater than the distance between the two sides of the stoppers that are close to each other, and the length of the yielding portion is greater than the thickness of the stoppers;

[0030] By adopting the above technical solution, when the control rod needs to pass through the stopper, the giving way part is rotated to be able to pass through the giving way space. After the giving way part of the control rod passes through the giving way space, the giving way part is rotated until both ends of the giving way part are opposite to the side of the stopper away from the initial position of the control rod, so that the stopper clamps the giving way part, and it is difficult for the giving way part to pass through the giving way space and return to the initial position, so that the control rod is locked in the locked position, reducing the possibility of the control rod returning to the initial position due to gravity or external force, and improving the stability of the control rod in the locked position.

[0031] Optionally, the control rod is provided with a locking assembly for limiting the rotation of the second rod body;

[0034] By adopting the above technical solution, when the yielding part enters the second state from the first state, the locking rod slides along the sliding groove, and the return spring is in a compressed state at this time. When the locking rod slides to align with the locking groove, the return spring pushes the locking rod toward the locking groove to restore the original state, so that the locking rod abuts against the hand-resisting rod and pushes the hand-resisting rod in a direction away from the locking groove, and the second rod body is locked at this time;

[0035] When unlocking is required, the hand lever is pushed toward the direction close to the locking groove, so that the locking lever slides out of the locking groove and slides back into the sliding groove.

[0039] By adopting the above technical solution, when the control rod slides from the initial position to the locking position, the snap plate on one of the two adjacent connecting plates penetrates into the snap groove of the other connecting plate, further improving the connection strength of the two connecting plates.

[0040] Optionally, the connecting member is a telescopic rod, one end of which is connected to a clamping plate, and the other end of which is rotatably connected to a control plate. A limit block is provided on the clamping plate, and the limit block limits the movement of the clamping plate in a vertical direction.

[0041] By adopting the above technical solution, the setting of the telescopic rod compensates for the horizontal displacement of the control rod, and the limit block limits the movement of the engaging plate in the vertical direction, so that the engaging plate can be driven to penetrate into the engaging groove when the control rod slides.

[0042] In summary, the present application includes at least one of the following beneficial technical effects:

[0043] 1. The column modules and beam modules can be freely combined according to different road conditions.

The locking rod 81 is slidably connected to the side wall of the circular boss 611, and the sliding direction of the locking rod 81 is parallel to the second state of the yielding portion 622. A mounting groove 612 is provided on the side wall of the circular boss 611, and the locking rod 81 slides in the mounting groove 612. A sliding groove 6212 for the locking rod 81 to slide is provided on the inner wall of the accommodating groove 6211, and the central angle of the sliding groove 6212 is 90 degrees. A locking groove 6213 for the locking rod 81 to penetrate is provided on the inner wall of one end of the sliding groove 6212. A reset spring 811 is fixedly connected to the side of the locking rod 81 away from the hand-resisting rod 82, and the end of the reset spring 811 away from the locking rod 81 is fixedly connected to the bottom wall of the mounting groove 612. One end of the hand-supporting rod 82 is located in the locking groove 6213, and the other end of the hand-supporting rod 82 passes through the hand-held part 623 and is slidably connected to the hand-held part 623. A positioning block is fixedly connected to the hand-supporting rod 82. A fixing groove 6214 for the hand-supporting rod 82 to slide is provided on the top surface of the connecting part 621. The fixing groove 6214 is connected to the locking groove 6213. A positioning groove for the positioning block to slide is provided on the inner wall of the fixing groove 6214, thereby reducing the possibility of the hand-supporting rod 82 sliding out of the connecting part 621. The side where the locking rod 81 abuts against the hand-supporting rod 82 and the side where the hand-supporting rod 82 abuts against the locking rod 81 are both wedge-shaped and cooperate with each other. The elastic force of the return spring 811 can overcome the gravity of the hand-supporting rod 82.

[0073] When the yielding part 622 enters the second state from the first state, the locking rod 81 slides along the sliding groove 6212, at which time the return spring 811 is in a compressed state. When the locking rod 81 slides to align with the locking groove 6213, the return spring 811 restores the original state and pushes the locking rod 81 toward the locking groove 6213, so that the locking rod 81 abuts against the hand-resisting rod 82 and pushes the hand-resisting rod 82 in a direction away from the locking groove 6213, at which time the second rod body 62 is locked. When the yielding part 622 needs to enter the first state from the second state, that is, when it needs to be unlocked, the hand-resisting rod 82 is pushed toward the locking groove 6213, so that the locking rod 81 slides to disengage from the locking groove 6213 and returns to the sliding groove 6212 to slide relative to the connecting part 621, at which time the hand-held part 623 can be rotated to drive the yielding part 622 from the second state to the first state.

[0074] According to actual conditions, the central angle of the sliding groove 33 and the sliding groove 413 is set to be slightly larger than 90 degrees, and the distance between the stopper 7 and the arc-shaped inner wall of the sliding groove 33 near the locking position of the control rod 6 is sufficient for the rotation of the yielding portion 622. When the control rod 6 is slid to the locking position, the sliding angle is first larger than 90 degrees, and then when the yielding portion 622 rotates 90 degrees from the first state to the second state, the two ends of the yielding portion 622 abut against the side of the stopper 7 away from the initial position of the control rod 6, and at this time, the sliding angle of the control rod 6 is exactly 90 degrees.

[0075] The mounting assembly 4 is also located on the mounting plate 13 to connect the top column 11 and the end cross beam 21. When the end cross beam 21 and the middle cross beam 22 or two adjacent middle cross beams 22 or the top column 11 and the end cross beam 21 are installed, the connecting plates 3 are assembled together so that the first unit tube 411 is inserted into the second annular groove 32 and the second unit tube 412 is inserted into the first annular groove 31. Since the first unit tube 411 and the second unit tube 412 are both semi-annular and can be assembled into a full ring, the first unit tube 411 is inserted into the second annular groove 32 and the second unit tube 412 is inserted into the first annular groove 31, so that the positioning of the two connecting plates 3 is automatically achieved, and the interlocking block 5 is inserted into the interlocking groove 51 to further position the two connecting plates 3. At this time, the interiors of the first unit tube 411 and the second unit tube 412 are connected, and then the first unit plate 421 and the second unit plate 422 are slid by sliding the control rod 6, so that the first unit plate 421 is located in the first unit tube 411 and the second unit tube 412 at the same time. Since the first unit plate 421 and the second unit plate 422 are both semi-annular, the first unit plate 421 automatically drives the second unit plate 422 to slide when sliding, so that the second unit plate 422 automatically slides with the first unit plate 421 until it is located in the second unit tube 412 and the first unit tube 411 at the same time.

[0076] During the sliding of the control rod 6, the yielding portion 622 is first in the first state. When the control rod 6 slides through the yielding space 71, the hand-held portion 623 is rotated to make the yielding portion 622 rotate ninety degrees, so that the control rod 6 is locked in the locking position by the block 7. At this time, the block 7 slides into the locking groove 6213 under the action of the return spring 811 and pushes the hand-supporting rod 82 to slide in the direction away from the bottom wall of the locking groove 6213. At this time, the second rod body 62 is locked.

[0077] When the two connecting plates 3 need to be disassembled, the control rod 6 is first slid a distance away from the locking rod 81, and then the hand lever 82 is pushed toward the bottom wall of the locking groove 6213, so that the stopper 7 slides out of the locking groove 6213 and can slide relatively along the sliding groove 6212, so that the yielding portion 622 can enter the first state from the second state, and then the hand-held portion 623 is rotated to make the yielding portion 622 rotate 90 degrees, and at this time the yielding portion 622 can pass through the yielding space 71. Then the control rod 6 is slid from the locking position to the initial position, driving the first unit plate 421 to slide to be completely located in the first unit tube 411 and the second unit plate 422 to be completely located in the second unit tube 412, thereby realizing the separation of the two connecting plates 3.

[0078] In summary, the disassembly and assembly of two adjacent connecting plates 3 can be achieved by simply rotating the control rod 6, without the need to install the bolts one by one on the connecting plates 3 or remove them one by one from the connecting plates 3. The operation is convenient and the disassembly and assembly efficiency of the end beams 21 and the middle beams 22 is improved.

[0079] Reference Figure 6 , Figure 7 and Fig.11 , the engaging block 5 is arranged near the locking position of the corresponding control rod 6, the connecting plate 3 is provided with an installation chamber 34, the installation chamber 34 is connected with the engaging groove 51 and the sliding groove 33, a clamping plate 35 is slidably arranged in the installation chamber 34, the engaging block 5 is provided with a clamping groove 36 for the clamping plate 35 to penetrate, and the clamping plate 35 is connected with the control rod 6 through a connecting member 37. The connecting member 37 is a telescopic rod, one end of the telescopic rod is fixedly connected with the clamping plate 35, and the other end of the telescopic rod is rotatably connected with the control plate, and the telescopic rod is extended and retracted with the sliding of the control rod 6, compensating for the horizontal displacement of the control rod 6. A limit block 9 is fixedly installed on the clamping plate 35, and a limit groove 91 for the limit block 9 to slide is provided on the inner wall of the installation chamber 34, and the limit block 9 and the limit groove 91 are both dovetail-shaped, and the limit block 9 limits the movement of the clamping plate 35 in the vertical direction, so that when the control rod 6 slides, it can drive the clamping plate 35 to penetrate into the clamping groove 36. When the control rod 6 slides from the initial position to the locking position, among the two adjacent connecting plates 3, the control rod 6 drives the locking plate 35 on one of the connecting plates 3 to penetrate into the locking groove 36 of the other connecting plate 3 through the telescopic rod, further improving the connection strength of the two connecting plates 3.

[0080] The implementation principle of a modular detachable door frame in the second embodiment of the present application is: when installing two adjacent middle beams 22 or end beams 21 and the middle beam 22 or the top column 11 and the end beam 21, the connecting plates 3 are spliced ​​together so that the first unit tube 411 is inserted into the second annular groove 32, and the second unit tube 412 is inserted into the first annular groove 31. Since the first unit tube 411 and the second unit tube 412 are both semi-annular and can be spliced ​​into a whole ring, the first unit tube 411 is inserted into the second annular groove 32 and the second unit tube 412 is inserted into the first annular groove 31, the positioning of the two connecting plates 3 is automatically achieved, and the interlocking block 5 is embedded in the interlocking groove 51 to further position the two connecting plates 3. At this time, the interiors of the first unit tube 411 and the second unit tube 412 are connected, and then the first unit plate 421 and the second unit plate 422 are slid by sliding the control rod 6, so that the first unit plate 421 is located in the first unit tube 411 and the second unit tube 412 at the same time. Since the first unit plate 421 and the second unit plate 422 are both semi-annular, the first unit plate 421 automatically drives the second unit plate 422 to slide when sliding, so that the second unit plate 422 automatically slides with the first unit plate 421 until it is located in the second unit tube 412 and the first unit tube 411 at the same time. During the sliding process of the control rod 6, the yielding portion 622 is first in the first state. When the control rod 6 slides through the yielding space 71, the hand-held portion 623 is rotated to make the yielding portion 622 rotate ninety degrees, so that the control rod 6 is locked in the locking position by the block 7. At this time, the block 7 slides into the locking groove 6213 under the action of the return spring 811 and pushes the hand-held rod to slide in the direction away from the bottom wall of the locking groove 6213. At this time, the second rod body 62 is locked and is not easy to rotate again.

[0081] When the two connecting plates 3 need to be disassembled, the control rod 6 is first slid a distance in the direction away from the locking rod 81, and then the hand lever 82 is pushed in the direction close to the bottom wall of the locking groove 6213, so that the stopper 7 slides out of the locking groove 6213 and can slide along the sliding groove 6212, so that the yielding part 622 can enter the first state from the second state, and then the hand-held part 623 is rotated to make the yielding part 622 rotate 90 degrees, and at this time the yielding part 622 can pass through the yielding space 71. Then the control rod 6 is slid from the locking position to the initial position, driving the first unit plate 421 to slide to be completely located in the first unit tube 411 and the second unit plate 422 to be completely located in the second unit tube 412, so as to separate the two connecting plates 3.

[0082] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
