Description

Technical Field

[0001] This utility model relates to the field of steel bar transportation technology, and in particular to a support device. Background Technology

[0002] Box girders are a special structural form of beams in bridge engineering. They are closed box-shaped beams composed of a top plate, bottom plate, web plate, and transverse and longitudinal diaphragms. Their hollow design can significantly improve torsional stiffness and is suitable for long-span bridges. The mesh in the steel reinforcement structure of the box girder that acts as a positioning and tensioning conduit is called the positioning mesh. The positioning mesh consists of multiple positioning mesh panels.

[0003] In related technologies, after the positioning mesh is welded, when transporting the positioning mesh, the transfer equipment grabs both ends to pick it up and put it down. When the transfer equipment grabs both ends of the positioning mesh, the middle part may fall and dent under its own weight, affecting the safety of the transfer operation and the quality of the positioning mesh. Utility Model Content

[0004] The purpose of this invention is to provide a support device that can support the positioning mesh during its movement.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] Support device, including:

[0007] Base;

[0008] A support frame is slidably mounted on the base in a vertical direction. The support frame is provided with a first sub-support, which extends horizontally and is elongated.

[0009] An adjusting frame is slidably connected to the support frame along the length direction of the first sub-support. The adjusting frame is provided with a second sub-support. The second sub-support extends horizontally and is elongated, parallel to the first sub-support. The first sub-support and the second sub-support constitute a cross support. The cross support is configured to support and position the mesh.

[0010] Linkage components are disposed on the base;

[0011] A driver is disposed on the base, and the support frame is connected to the output end of the driver. When the driver drives the support frame to rise, the linkage causes the adjusting frame to move away from the support frame.

[0012] Preferably, the support frame is provided with a receiving groove, and the adjusting frame is slidably connected to the receiving groove. When the driver drives the support frame to rise, the adjusting frame extends out of the receiving groove.

[0013] Preferably, one of the base and the support frame is provided with a slide rail, and the other is provided with a slider, with the slider slidably connected to the slide rail.

[0014] Preferably, the support frame includes a support plate and a support rod connected to each other, the support plate is slidably connected to the base, the support rod extends horizontally, and the first sub-support is disposed at the top of the support rod.

[0015] Preferably, the adjustment frame includes;

[0016] An adjusting rod extends horizontally and is slidably connected to the support frame, with the second sub-support located at the top of the adjusting rod;

[0017] A guide wheel is rotatably mounted on the adjusting rod. The linkage is provided with a push groove, and the guide wheel is disposed in the push groove. When the driver drives the support frame to rise, the linkage pushes the guide wheel through the push groove.

[0018] Preferably, the adjusting frame further includes a connecting block, which is fixedly connected to the adjusting rod, and the guide wheel is rotatably mounted on the connecting block.

[0019] Preferably, the support frame is provided with a horizontally extending guide groove, and the connecting block is slidably connected to the guide groove.

[0020] Preferably, two adjustment frames are slidably arranged on the support frame. When the driver drives the support frame to rise, the linkage causes the two adjustment frames to move in opposite directions.

[0021] Preferably, the driver can drive the support frame to move between an upper stop position and a lower stop position. When the support frame is in the upper stop position, the length of the cross brace is the longest, and when the support frame is in the lower stop position, the length of the cross brace is the shortest.

[0022] Preferably, in the horizontal direction, the linkage is located on one side of the cross brace. When the support frame is in the lower stop position, the linkage extends above the cross brace. When the support frame is in the upper stop position, the linkage retracts from above the cross brace.

[0023] The beneficial effects of this utility model are:

[0024] The support device of this utility model can assist in the transfer of positioning net sheets. In the initial state, the adjusting frame is retracted relative to the support frame, occupying little space. When the transfer equipment grabs the two ends of the positioning net sheet and rises, the support frame supports the bottom of the middle of the positioning net sheet under the drive of the driver. As the positioning net sheet rises, the linkage drives the adjusting frame away from the support frame, saving power. This allows the second sub-support to extend relative to the first sub-support, increasing the length of the cross support formed by the first and second sub-supports. This provides safer and more reliable support and protection for the bottom of the middle of the positioning net sheet, preventing it from falling and bending under its own weight, ensuring the safety of the transfer operation and the quality of the positioning net sheet.

[0038] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0039] like Figures 1 to 3 As shown, this utility model provides a support device, including a base 1, a support frame 2, an adjusting frame 3, a linkage 4, and a driver 5. The support frame 2 is slidably mounted vertically on the base 1. The support frame 2 has a first sub-support 221, which extends horizontally and is elongated. The adjusting frame 3 is slidably connected to the support frame 2 along the length of the first sub-support 221. The adjusting frame 3 has a second sub-support 311, which extends horizontally and is elongated, parallel to the first sub-support 221. The first sub-support 221 and the second sub-support 311 constitute a horizontal support, which is configured to support a positioning mesh 100. The linkage 4 is mounted on the base 1, and the driver 5 is mounted on the base 1. The support frame 2 is connected to the output end of the driver 5. When the driver 5 drives the support frame 2 to rise, the linkage 4 moves the adjusting frame 3 away from the support frame 2.

[0040] The support device of this utility model can assist in the transfer of the positioning net sheet 100. In the initial state, the adjusting frame 3 is retracted relative to the support frame 2, occupying little space. When the transfer equipment grabs the two ends of the positioning net sheet 100 and rises, the support frame 2 is supported at the bottom middle of the positioning net sheet 100 under the drive of the driver 5. As the positioning net sheet 100 rises, during the rise of the support frame 2, the linkage 4 drives the adjusting frame 3 away from the support frame 2, saving power source, so that the second sub-support 311 extends relative to the first sub-support 221. The length of the cross support formed by the first sub-support 221 and the second sub-support 311 increases, which can more safely and reliably support and protect the bottom middle of the positioning net sheet 100, avoiding it from falling and bending under its own weight, ensuring the safety of the transfer operation and the quality of the positioning net sheet 100.

[0041] Specifically, the support frame 2 is provided with a receiving groove, and the adjusting frame 3 is slidably connected to the receiving groove. When the driver 5 drives the support frame 2 to rise, the adjusting frame 3 extends out from the receiving groove. The above configuration allows the adjusting frame 3 to slide more precisely relative to the support frame 2, eliminating the need for external sliding fittings, saving space, and reducing the overall weight.

[0042] More specifically, both the base 1 and the support frame 2 are equipped with a slide rail 11 and a slider, respectively, with the slider slidably connected to the slide rail 11. This arrangement allows the support frame 2 to slide up and down more smoothly relative to the base 1.

[0043] In this embodiment, a vertically extending slide rail 11 is provided on the base 1, and a slider is provided on the support frame 2.

[0044] Specifically, the support frame 2 includes a support plate 21 and a support rod 22 connected to each other. The support plate 21 is slidably connected to the base 1, and the support rod 22 extends horizontally. A first sub-support 221 is disposed on the top of the support rod 22. The above configuration is simple in structure and can reliably support the positioning mesh 100.

[0045] In this embodiment, the support plate 21 and the support rod 22 are connected side by side in the horizontal direction, the slider is fixed to the support plate 21, the receiving groove is provided at the end of the support rod 22, and the first sub-support 221 is the wall surface of the top of the support rod 22.

[0046] Specifically, the adjusting frame 3 includes an adjusting rod 31 and a guide wheel 32. The adjusting rod 31 extends horizontally and is slidably connected to the support frame 2. A second sub-support 311 is located at the top of the adjusting rod 31. The guide wheel 32 is rotatably mounted on the adjusting rod 31. The linkage 4 is provided with a pushing groove 41, in which the guide wheel 32 is positioned. When the driver 5 drives the support frame 2 to rise, the linkage 4 pushes against the guide wheel 32 through the pushing groove 41. This configuration allows the linkage 4 to smoothly move the adjusting frame 3.

[0047] More specifically, the adjusting frame 3 also includes a connecting block 33, which is fixedly connected to the adjusting rod 31, and the guide wheel 32 is rotatably mounted on the connecting block 33. This arrangement allows the guide wheel 32 to be more reliably positioned on the adjusting rod 31.

[0048] More specifically, the support frame 2 is provided with a horizontally extending guide groove 211, and the connecting block 33 is slidably connected to the guide groove 211. This arrangement allows the connecting block 33 to drive the support rod 22 to move more stably.

[0049] In this embodiment, the adjusting rod 31 and the support rod 22 are coaxially arranged. The adjusting rod 31 slides through the receiving groove. The outer wall of the support rod 22 is provided with a notch communicating with the receiving groove. The connecting block 33 passes through the notch and is connected to the adjusting rod 31. The second sub-support 311 is the wall surface of the top of the adjusting rod 31. It pushes the sliding groove 41 and extends obliquely. The guide groove 211 is provided on the support plate 21.

[0050] In one embodiment, an adjustment frame 3 is slidably disposed on the support frame 2, and a first sub-support 221 and a second sub-support 311 constitute a cross support, which has a simple structure and reliable adjustment.

[0051] In another embodiment, two adjusting frames 3 are slidably arranged on the support frame 2. When the driver 5 drives the support frame 2 to rise, the linkage 4 drives the two adjusting frames 3 to move in opposite directions. A first sub-support 221 and two second sub-supports 311 constitute a cross support. When the two adjusting rods 31 extend relative to the support rod 22, the length of the cross support is longer, and the support for the positioning net sheet 100 is more reliable.

[0052] In the above embodiment, the two ends of the support rod 22 are respectively provided with receiving grooves, and an adjusting rod 31 is inserted into each receiving groove. Each adjusting rod 31 is provided with a pushing slide groove 41. The two pushing slide grooves 41 are arranged at an angle. The two pushing slide grooves 41 can be on one linkage member 4 or can be respectively provided on two linkage members 4.

[0053] Specifically, the driver 5 can drive the support frame 2 to move between the upper stop position and the lower stop position. When the support frame 2 is in the upper stop position, the length of the cross brace is the longest, and when the support frame 2 is in the lower stop position, the length of the cross brace is the shortest. The above settings make the length adjustment of the cross brace more precise.

[0054] More specifically, in the horizontal direction, the linkage 4 is located on one side of the cross brace. When the support frame 2 is in the lower stop position, the linkage 4 extends above the cross brace; when the support frame 2 is in the upper stop position, the linkage 4 retracts from above the cross brace. This arrangement allows the linkage 4 to limit and protect the positioning mesh 100 on the cross brace from one side when the support frame 2 is in the lower stop position.

[0055] In this embodiment, the driver 5 is a cylinder, which is fixed to the base 1, and the piston rod is connected to the support plate 21.

[0056] In other embodiments, the actuator 5 may also be a hydraulic cylinder, an electric cylinder, etc.

[0057] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
