Abstract
Description
Technical Field
[0001] This utility model relates to the field of early warning equipment technology, specifically to a collision early warning device for a rotating support leg. Background Technology
[0002] During the rotation of the swing bridge, the supporting legs bear the weight of the entire rotating structure, transferring the load of the rotating part to the lower foundation, ensuring the stability of the rotating structure during rotation, and preventing the structure from tilting or changing due to uneven stress. The cooperation between the supporting legs and the sliding track can control the speed and direction of rotation. Through precise design and construction, the swing bridge can be accurately rotated to the predetermined position, achieving high rotation accuracy requirements and ensuring the accuracy and reliability of the bridge when it is closed.
[0003] Currently, the slides used with the support legs are constructed by splicing and combining. During the splicing process, it is necessary to ensure the flatness of the joints. When there is slight misalignment at the joints of the slides, it will hinder the normal operation of the support legs. When there is significant misalignment at the joints of the slides, it will directly hinder the normal operation of the support legs. Therefore, a collision warning device for the support legs used for rotation is proposed. Utility Model Content
[0004] In order to solve the technical problems existing in the prior art, the present invention provides a collision warning device for rotating support legs.
[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a collision warning device for a rotating support foot, including a base bracket and a segmented slide. Several sets of the base brackets are arranged around a rotating base to form an annular support platform. Several sets of segmented slides are laid end to end on the surface of the base brackets to form an annular slide. Several sets of support feet for supporting the rotating bridge pier are provided on the surface of the annular slide. A slide collision warning device is provided on one side of the bottom of the support foot. The slide collision warning device includes an extension rod provided on the bottom surface of the support foot, an angle adjustment part fixed to one end of the extension rod by bolts, a drop sensing component sleeved inside the angle adjustment part, and a laser measuring part installed on the other end of the extension rod.
[0006] The extension rod rotates synchronously with the support leg, causing the drop sensing component at the end of the angle adjustment unit to rotate synchronously. During the rotation, the drop sensing component senses the drop at the joint of the adjacent two sections of the slide rail, and the laser measurement unit detects the sliding amplitude of the drop sensing component.
[0007] Preferably, the extension rod includes an extension rod body and a limiting bolt. A connecting shaft is welded to the bottom surface of the support foot. The extension rod body is sleeved on the outside of the connecting shaft. The limiting bolt is threaded into the inside of the connecting shaft. The limiting bolt presses down to fix the extension rod body.
[0008] Preferably, the extension rod further includes a connecting bolt, which is threaded to the end of the extension rod body, and the angle adjustment part is fixed to the end side of the extension rod body by the threaded connection with the connecting bolt.
[0009] Preferably, the angle adjustment part includes a connecting protrusion, a connecting sleeve, and a limiting hole. The connecting protrusion is fixed to the end of the extension rod body by a threaded connection with a connecting bolt. The connecting sleeve is formed at the side of the connecting protrusion. The limiting hole is opened at the center of the connecting sleeve. The drop sensing component is sleeved in the limiting hole.
[0010] Preferably, the drop sensing component includes a movable rod, a roller, a clamp, and a reflector. The movable rod is sleeved in a limiting hole, the roller is mounted on the bottom end of the movable rod via a rotating shaft, the clamp is disposed at the top end of the movable rod, and the reflector is clamped inside the clamp.
[0011] Preferably, the laser measuring unit includes an adjustable connector and a laser detector, the adjustable connector being disposed on the top of the limiting bolt, and the laser detector being fixed to the top of the adjustable connector.
[0012] Preferably, the top of the limiting bolt has a groove for inserting an adjustable connecting seat, and the adjustable connecting seat is fixed inside the limiting bolt by contact friction with the limiting bolt.
[0013] Preferably, the laser emission direction of the laser detector is perpendicular to the setting direction of the reflector, and the height of the reflector is greater than the movable stroke length of the movable rod.
[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0015] 1. This utility model is equipped with a slide collision warning device. The extension rod in the slide collision warning device rotates synchronously with the rotation of the support foot, causing the drop sensing component at the end of the angle adjustment part to rotate synchronously. The drop sensing component senses the drop at the joint of the adjacent two sections of slide during rotation. The laser measurement unit detects the sliding amplitude of the drop sensing component. When the data measured by the laser measurement unit exceeds the limit, the laser measurement unit can issue a warning message.
[0016] In this invention, the height difference sensing component includes a movable rod, a roller, a clamp, and a reflector. The roller generates vertical displacement due to the height difference, and the vertical displacement of the roller synchronously drives the movable rod to move vertically. The reflector set on the top of the movable rod moves vertically at the same time. The vertically moving reflector provides a clear target for laser irradiation and reduces the influence of the external environment on laser irradiation. Attached Figure Description

[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments, highlighting the above and other technical features and advantages of the present invention. However, the following embodiments are merely preferred embodiments of the present invention and are not exhaustive.
[0025] Example:
[0026] like Figure 1 - Figure 5 As shown, this utility model provides a collision warning device for a rotating support leg, including a base support 1 and a segmented slide 2. Several sets of base supports 1 are arranged around a rotating base to form an annular support platform. Several sets of segmented slides 2 are laid end to end on the surface of the base support 1 to form an annular slide. Several sets of support legs 3 for supporting the rotating bridge pier are provided on the surface of the annular slide. A slide collision warning device 4 is provided on one side of the bottom of the support leg 3. The slide collision warning device 4 includes an extension rod 41 provided on the bottom surface of the support leg 3, an angle adjustment part 42 fixed to one end of the extension rod 41 by bolts, a drop sensing component 43 sleeved inside the angle adjustment part 42, and a laser measuring part 44 installed on the other end of the extension rod 41.
[0027] As the extension rod 41 rotates with the support leg 3, the drop sensing component 43 at the end of the angle adjustment unit 42 rotates synchronously. The drop sensing component 43 senses the drop at the joint of the adjacent two sections of the slide rail 2 during rotation, and the laser measurement unit 44 detects the sliding amplitude of the drop sensing component 43.
[0028] The extension rod 41 includes an extension rod body 411 and a limiting bolt 412;
[0029] A connecting shaft 31 is welded to the bottom surface of the support foot 3. The extension rod body 411 is sleeved on the outside of the connecting shaft 31. The limiting bolt 412 is threaded into the inside of the connecting shaft 31. The limiting bolt 412 presses down to fix the extension rod body 411. The extension rod body 411 can rotate relative to 11. The extension rod body 411 adjusts its own setting position by rotating, so as to better adapt to the annular slide formed by the segmented slide 2 with different curvatures.
[0030] The extension rod 41 also includes a connecting bolt 413, which is threaded to the end of the extension rod body 411. The angle adjustment part 42 is fixed to the end side of the extension rod body 411 by threaded connection with the connecting bolt 413. The angle adjustment part 42 includes a connecting protrusion 421, a connecting sleeve 422 and a limiting hole 423.
[0031] The connecting protrusion 421 is fixed to the end of the extension rod body 411 by the threaded connection with the connecting bolt 413. The connecting sleeve 422 is formed on the side of the connecting protrusion 421. The limiting hole 423 is opened at the center of the connecting sleeve 422. The connecting sleeve 422 can be adjusted in angle with the cooperation of the connecting protrusion 421 and the connecting bolt 413 to obtain an inclined setting angle. The inclined setting angle can better enable the drop sensing component 43 set inside the angle adjustment part 42 to avoid the misalignment of the segmented slide 2. At the same time, the inclined design of the connecting protrusion 421 can also better rotate around the bolt to avoid the problem of rigid deformation caused by the drop sensing component 43 directly colliding with the segmented slide 2 when a large angle misalignment occurs.
[0032] The drop sensing component 43 is fitted inside the limiting hole 423. The drop sensing component 43 includes a movable rod 431, a roller 432, a clamping piece 433, and a reflector 434.
[0033] The movable rod 431 is fitted into the limiting hole 423. The roller 432 is installed at the bottom of the movable rod 431 via a rotating shaft. The clamping plate 433 is set at the top of the movable rod 431. The reflector 434 is clamped inside the clamping plate 433. During the operation of the drop sensing component 43, the roller 432 is always in contact with the segmented slide 2. When a height difference occurs at the connection between the two segments of the segmented slide 2, the roller 432 will generate a vertical displacement through the height difference. The vertical displacement of the roller 432 will synchronously drive the movable rod 431 to move vertically. The reflector 434 set at the top of the movable rod 431 will move vertically at the same time. The vertically moving reflector 434 provides a clear target for laser irradiation.
[0034] The laser measurement unit 44 includes an adjustable connecting seat 441 and a laser detector 442. The adjustable connecting seat 441 is disposed on the top of the limiting bolt 412, and the laser detector 442 is fixed to the top of the adjustable connecting seat 441. The top of the limiting bolt 412 has a groove for the adjustable connecting seat 441 to be inserted. The adjustable connecting seat 441 is fixed in the limiting bolt 412 by contact friction with the limiting bolt 412. After the position of the reflector 434 is fixed, the adjustable connecting seat 441 is inserted into the groove. After insertion, the position of the adjustable connecting seat 441 in the limiting bolt 412 is adjusted by rotation, so that the laser generating part of the laser detector 442 is aligned with the reflector 434. After alignment, the limiting bolt 412 fixes the adjustable connecting seat 441 by friction.
[0035] The laser emitted by the laser detector 442 is perpendicular to the setting direction of the reflector 434. The laser emitted by the laser detector 442 can accurately illuminate the laser detector 442, thereby ensuring that the laser detector 442 can stably measure the range of motion of the reflector 434 through the laser. The height of the reflector 434 is greater than the movable stroke height of the movable rod 431. During the movement, the reflector 434 can always serve as the target of the laser generated by the laser detector 442, avoiding the problem of misalignment and loss of the target.
[0036] The above description is merely a preferred embodiment of the present utility model and is illustrative rather than restrictive. Those skilled in the art will understand that many changes, modifications, and even equivalents can be made within the spirit and scope defined by the claims of the present utility model, all of which will fall within the protection scope of the present utility model.
