Description

Technical Field

[0001] The present application relates to the field of bridge construction auxiliary devices, and in particular to a device for passing through bridge expansion joints during construction. Background Art

[0002] In the existing bridge expansion joint construction, after the expansion joint device is installed and leveled, before pouring concrete or before the concrete reaches the design strength, when construction vehicles need to pass, mainly measures such as padding wooden squares or steel plates are taken.

[0003] When taking the measure of padding steel plates, affected by the stress characteristics of the material structure, it is easily affected by the vehicle load, causing the deformation of the expansion joint device. After installing the padding expansion joint device, the elevation needs to be readjusted. Moreover, the wheelbases of the construction vehicles passing through the steel plates are different, and manual cooperation with lifting equipment is required to move them, which is time-consuming and laborious, not easy to ensure the quality and increases the construction cost. Utility Model Content

[0004] In order to facilitate the passage of construction vehicles through bridge expansion joints, the present application provides a device for passing through bridge expansion joints during construction.

[0005] The device for passing through bridge expansion joints during construction provided by the present application adopts the following technical solutions:

[0006] A device for passing through bridge expansion joints during construction includes a plurality of support plates. Each support plate is arranged in an arched shape with the middle position bent upward. A reinforcing member for reinforcing the shape of the support plate is fixedly connected to the lower side of each support plate. A slider is connected to the lower side of each support plate, and a slide rail for the slider to slide and insert is provided on the lower side of the support plate. The slide rail is connected with a driving component for driving the slider and the support plate connected to the slider to move.

[0007] By adopting the above technical solutions, by setting the driving component to drive the connected slider and support plate to move, when the wheelbase of the vehicle passing through the expansion joint changes, the relative position of the two expansion plates can be driven to move by the driving component, reducing the trouble of the staff carrying the support plate for movement.

[0008] Optionally, the driving component includes a relative hydraulic cylinder between two adjacent sliders inside the slide rail, and the relative hydraulic cylinder is fixedly connected to the two adjacent sliders.

[0009] By adopting the above technical solutions, when it is necessary to adjust the relative position of two adjacent support plates, the relative hydraulic cylinder is opened. During the movement of the relative hydraulic cylinder, the connected slider and support plate are driven to move, thereby realizing the process of driving the support plate to move.

[0010] Optionally, the driving assembly further includes an integral hydraulic cylinder located on the side of the slider connected to the opposing hydraulic rod away from the connected opposing hydraulic cylinder and fixedly connected to the slider.

[0011] By adopting the above technical solution, when it is necessary to move the two connected support plates simultaneously, the integral hydraulic cylinder is activated. During the movement of the integral hydraulic cylinder, the two connected support plates are driven to move, thus reducing the trouble for vehicles passing through the expansion joint to adjust their positions and move to the position of the support plates.

[0012] Optionally, the reinforcement member is a rib plate, and a plurality of rib plates arranged at an angle to the support plate are fixedly connected to the lower side of each support plate. A groove spanning adjacent expansion joints is provided on the side of each rib plate away from the support plate.

[0013] By adopting the above technical solution, by setting the reinforcement member as a rib plate, the phenomenon that the shape of the support plate changes when a vehicle passes over the upper side of the support plate, thus requiring adjustment of the shape of the support plate, is reduced.

[0014] Optionally, each support plate is connected to a plurality of sliding members for supporting the support plate and driving the support plate to move.

[0015] By adopting the above technical solution, by setting the sliding members, the phenomenon that the support plate slides and abuts against the upper surface of the bridge during movement, affecting the structural integrity and aesthetics of the upper surface of the bridge, is reduced.

[0016] Optionally, the sliding member is a sliding wheel.

[0017] By adopting the above technical solution, by setting the sliding wheels, the support plate can be driven to move by the sliding wheels.

[0018] Optionally, each slider is slidably inserted between a plurality of rib plates on the lower side of the connected support plate, and each slider is connected to a linkage assembly for driving the connected plurality of sliding wheels to move up and down.

[0019] By adopting the above technical solution, by setting the linkage assembly, when it is necessary to move the support plate, the sliding wheels can be driven by the linkage assembly to move so that the sliding wheels support the support plate. When a vehicle needs to pass, the linkage assembly drives the sliding wheels to move between the rib plates, reducing the phenomenon that the support plate is unstable due to the sliding wheels supporting the support plate when a vehicle passes.

[0020] Optionally, the linkage assembly includes a linkage motor located inside the slider. The output shaft of the linkage motor is fixedly sleeved with a driving pulley. A driven pulley is connected to the upper side of each sliding wheel. Each driven pulley is connected to the adjacent driving pulley by a connecting belt. Each driven pulley is penetrated and threadedly inserted with a driving lead screw. Each driving lead screw is connected to the adjacent sliding wheel and can drive the connected sliding wheel to move up and down.

[0021] By adopting the above technical solution, when it is necessary to move the sliding wheel, the linkage motor is started. The linkage motor drives the connected driving pulley to rotate. During the rotation of the driving pulley, it drives the connected driven pulley to rotate. During the rotation of the driven pulley, it drives the connected driving lead screw to move. During the movement of the driving lead screw, it drives the connected sliding wheel to move, thereby realizing the process of the linkage assembly driving the sliding wheel to move.

[0022] In summary, the present application includes at least one of the following beneficial technical effects:

[0023] 1. By providing the support plate and the driving assembly, the labor caused by the need for workers to manually carry the support plate when the size and position of the vehicle passing through the expansion joint change is reduced.

[0024] 2. By providing the rib plate, the phenomenon that the shape of the support plate changes after the vehicle passes through the upper side of the support plate, thereby affecting the subsequent use of the support plate, is reduced.

[0025] 3. By providing the sliding member and the linkage assembly, the phenomenon that the bottom side wall of the support plate abuts against the upper surface of the bridge during the process of moving the support plate, thereby damaging the aesthetics and structure of the upper surface of the bridge, is reduced.

Detailed implementation manners

[0031] The following further describes the present application in detail with reference to the Figure 1 - attached Figure 4 drawings.

[0032] An embodiment of the present application discloses a device for passing through a bridge expansion joint during construction.

[0033] Embodiment 1

[0034] Referring to Figure 1 and Figure 2 , a device for passing through a bridge expansion joint during construction includes two support plates 1. Each support plate 1 is arranged in an arch shape, and the middle position of each arched support plate 1 is upward. A reinforcement member 2 is connected to the lower side of each support plate 1. In this embodiment, the reinforcement member 2 is set as a rib plate 21, and each support plate 1 is connected with a plurality of rib plates 21. Each rib plate 21 is fixedly connected to the lower side of the support plate 1 and is perpendicular to the support plate 1. Grooves are formed in the lower side wall of each rib plate 21, and the length of the groove is greater than the width of the adjacent expansion joint, so that both ends of the lower side wall of each rib plate can abut against the side wall of the bridge around the expansion joint.

[0035] A slider 3 is provided on the lower side of each support plate 1. The slider 3 is vertically arranged and fixedly connected to the support plate 1. A slide rail 4 arranged along the length direction of the expansion joint is provided inside the expansion joint of the bridge. One end of each slider 3 away from the support plate 1 is inserted into the inside of the slide rail 4 and is slidably connected to the slide rail 4 along the length direction of the slide rail 4.

[0036] The slide rail 4 is connected with a drive assembly 5 for driving the slider 3 to move.

[0037] During actual use, according to the size of the wheelbase of the vehicle currently required to pass through the expansion joint, the drive assembly 5 is started to drive the two connected sliders 3 to move. During the movement of each slider 3, the connected support plate 1 is driven to move, so that the two support plates 1 can support the vehicle currently required to pass through the expansion joint, thus facilitating the process of supporting the vehicle passing through the expansion joint.

[0038] Moreover, since a plurality of rib plates 21 are connected to the lower side of the support plate 1, the support of the arched state of the support plate 1 can be realized, making the shape of the support plate 1 more stable. Further, since grooves with lengths greater than the width of the expansion joint are provided on the lower side of each rib plate 21, the protection of the internal structure of the expansion joint is realized.

[0039] The driving assembly 5 includes a relative hydraulic cylinder 51 located between the two sliders 3. The relative hydraulic cylinder 51 is horizontally arranged, and each end of the relative hydraulic cylinder 51 is fixedly connected to the adjacent slider 3.

[0040] During actual use, when it is necessary to adjust the relative position between the two support plates 1 so that the support plate 1 can support the vehicle passing through the expansion joint, the relative hydraulic cylinder 51 is activated. The relative hydraulic cylinder 51 drives the connected slider 3 to move, and the slider 3 drives the connected support plate 1 to move during the movement, thereby realizing the adjustment of the relative position between the two support plates 1.

[0041] The driving assembly 5 further includes an overall hydraulic cylinder 52 located on one side of one slider 3 away from the other slider 3. The overall hydraulic cylinder 52 is horizontally arranged and the piston rod is fixedly connected to the adjacent slider 3.

[0042] During actual use, the two support plates 1 can be driven to move along the length direction of the expansion joint by activating the overall hydraulic cylinder 52, so that the support plate 1 can adapt to vehicles in more positions, thus facilitating the process of the vehicle passing through the expansion joint.

[0043] The implementation principle of Embodiment 1 is: when a vehicle needs to pass through the expansion joint, the overall hydraulic cylinder 52 is activated to drive the two support plates 1 to move to a position close to the vehicle. Then, according to the wheelbase size of the vehicle, the relative hydraulic cylinder 51 is started, so that the two support plates 1 can support the vehicle simultaneously. Then the vehicle can pass through the expansion joint.

[0044] Embodiment 2

[0045] Refer to Figure 3 and Figure 4 In this embodiment, the difference from Embodiment 1 is that a plurality of sliding members 6 for driving the support plate 1 to move are connected to the lower side of each support plate 1. In this embodiment, the sliding member 6 is set as a sliding wheel 61, and a pulley seat 62 is installed on the upper side of each sliding wheel 61. Each pulley seat 62 is slidably inserted between two adjacent rib plates 21 in the vertical direction and is in sliding contact with the rib plate 21. In this embodiment, the number of sliding wheels 61 connected to each support plate 1 is set to two, and the two sliding wheels 61 are arranged oppositely.

[0046] The upper end of each slider 3 is slidably inserted between two adjacent rib plates 21. Each support plate 1 is further connected with a linkage assembly 7 for driving the sliding wheel 61 to move up and down.

[0047] During actual use, when it is necessary to move the support plate 1, start the linkage assembly 7. The linkage assembly 7 drives the connected sliding wheel 61 to move downward, so that the support plate 1 can be supported by the sliding wheel 61, and thus the support plate 1 can move more conveniently during the movement.

[0048] The linkage assembly 7 includes a linkage motor 71 located inside the slider 3. A driving pulley 72 is fixedly sleeved on the output shaft of the linkage motor 71. A driven pulley 73 is provided on the upper side of each pulley seat 62. The same connecting belt 74 is sleeved between each driven pulley 73 and the adjacent driving pulley 72.

[0049] Each driven pulley 73 is penetrated and threadedly connected with a driving lead screw 75. Each driving lead screw 75 is vertically arranged and the lower end of each driving lead screw 75 is fixedly connected with the adjacent pulley seat 62. Each driving lead screw 75 is slidably sleeved with a limiting plate 76, and the side wall of each limiting plate 76 is fixedly connected with the side wall of the adjacent rib plate 21. A limiting rod 77 is fixedly connected to the upper side of each pulley seat 62, and each limiting rod 77 penetrates through the limiting plate 76 and is slidably connected with the limiting plate 76.

[0050] The implementation principle of Embodiment 2 is as follows: When it is necessary to move the support plate 1, first start the linkage motor 71. The linkage motor 71 drives the connected driving pulley 72 to rotate. During the rotation of the driving pulley 72, it drives the connected driven pulley 73 to rotate. During the rotation of the driven pulley 73, it drives the connected driving lead screw 75 to move. During the movement of the driving lead screw 75, it drives the connected pulley seat 62 to move downward, so that the sliding wheel 61 can move downward and support the support plate 1. During the movement, the rotation of the sliding wheel 61 drives the support plate 1 to move, so that the support plate 1 can move more smoothly.

[0051] The above are all the preferred embodiments of this application. The protection scope of this application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
