Description

Technical Field

[0001] This utility model relates to the field of suspension bridge deck removal technology, specifically to a suspension bridge deck removal device. Background Technology

[0002] A suspension bridge, also known as a suspension bridge, is a bridge whose superstructure is mainly supported by cables that are suspended from towers and anchored to both banks. The geometry of the cables is determined by the equilibrium of forces and is generally close to a parabola. In the process of dismantling a suspension bridge, it is usually necessary to remove its deck panels first, which requires the use of deck panel removal equipment.

[0003] Among them, a suspension bridge deck removal device with announcement number CN206625141U includes traveling wheels located on the bridge deck, front crossbeams installed on several traveling wheels on the front side, rear crossbeams installed on several traveling wheels on the rear side, longitudinal beams installed on the front and rear crossbeams, counterweights installed on the front surface of the longitudinal beams, and two or more sets of upper crossbeams installed on the rear surface of the longitudinal beams. Each set of upper crossbeams is equipped with two or more lifting systems. The lifting system includes an installation plate located on the upper crossbeam, a lifting device installed on the installation plate, an upper anchor plate installed on the top of the lifting device, threaded steel bars inserted into the upper anchor plate, the bottom of the threaded steel bars being located below the longitudinal beams, and a lower anchor plate being installed below it.

[0004] However, the existing suspension bridge deck removal device requires each lower anchor plate to be fixedly connected to the deck during use, which consumes a lot of the physical strength and energy of the workers, thus greatly reducing the efficiency of deck removal. Utility Model Content

[0005] In view of the problems existing in the above-mentioned suspension bridge deck removal devices, this utility model is proposed.

[0006] Therefore, the purpose of this utility model is to provide a suspension bridge deck removal device, which solves the problem that existing suspension bridge deck removal devices require each lower anchor plate to be fixedly connected to the deck during use, which consumes a lot of physical strength and energy of the workers and greatly reduces the efficiency of deck removal.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A suspension bridge deck removal device includes a base, an L-shaped plate fixedly connected to the upper surface of the base, two lifting cylinders fixedly connected to the upper surface of the L-shaped plate, a movable plate fixedly connected to the output ends of the two lifting cylinders, a rotating rod rotatably connected to the lower surface of the movable plate, multiple through holes opened on the upper surface of the L-shaped plate, and a strip block fixedly connected to the lower end of each rotating rod through the corresponding through hole. A driving mechanism is provided on the upper surface of the L-shaped plate, and each rotating rod rotates through the driving mechanism.

[0009] Preferably, the drive mechanism includes a bidirectional cylinder, two mounting plates, multiple racks, and multiple gears. The bidirectional cylinder is fixedly connected to the upper surface of the L-shaped plate. The two mounting plates are respectively fixedly connected to the two output ends of the bidirectional cylinder. Each rack is symmetrically fixedly connected to one side of the mounting plate. Each gear is fixedly sleeved on the rod wall of the corresponding rotating rod. Each rack meshes with the corresponding gear.

[0010] Preferably, each of the rotating rods has a symmetrically fixedly connected limit strip on its rod wall, and each of the through holes has a symmetrically formed limit groove on its inner wall, with each limit strip matching the corresponding limit groove.

[0011] Preferably, the lower end of each of the strip blocks is tapered.

[0012] Preferably, a counterweight is fixedly connected to the upper surface of the base.

[0013] Preferably, each of the strip blocks has an anti-slip groove on its upper surface.

[0014] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0015] 1. This utility model, by activating the lifting cylinder, causes the moving plate to move upward, then each rotating rod moves upward, then the base moves and positions it on the upper surface of the bridge panel. Then the lifting cylinder is activated again to cause each rotating rod to move downward, thereby moving each strip block to the bottom of the bridge panel. Then each rotating rod is rotated to make the strip block rotate. Finally, the lifting cylinder is activated to cause the moving plate to move upward, so that each strip can lift the bridge panel. In this process, the physical exertion of the workers can be greatly reduced.

[0016] 2. In this utility model, by activating the bidirectional cylinder, the two mounting plates can be moved, thereby allowing each rack to move, which in turn drives the corresponding gear to rotate, and subsequently drives each rotating rod to rotate. Attached Figure Description

[0024] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0025] This utility model discloses a suspension bridge deck removal device.

[0026] This utility model provides, for example Figure 1-3 The suspension bridge deck removal device shown includes a base 1, an L-shaped plate 2 fixedly connected to the upper surface of the base 1, two lifting cylinders 3 fixedly connected to the upper surface of the L-shaped plate 2, a moving plate 4 fixedly connected to the output ends of the two lifting cylinders 3, a rotating rod 5 rotatably connected to the lower surface of the moving plate 4, multiple through holes opened on the upper surface of the L-shaped plate 2, and a strip block 6 fixedly connected to the lower end of each rotating rod 5 through the corresponding through hole. A driving mechanism is provided on the upper surface of the L-shaped plate 2, and each rotating rod 5 is rotated by the driving mechanism.

[0027] Activate lifting cylinder 3 to move moving plate 4 upward, then each rotating rod 5 moves upward, then moves base 1 and positions it on the upper surface of bridge panel. Activate lifting cylinder 3 again to move each rotating rod 5 downward, thereby moving each strip block 6 to below bridge panel. Rotate each rotating rod 5 to rotate strip block 6. Finally, activate lifting cylinder 3 to move moving plate 4 upward, allowing each strip block 6 to lift bridge panel. This process greatly reduces the physical exertion of workers.

[0028] In order for each lever 5 to rotate, such as Figure 1-3 As shown, the drive mechanism includes a bidirectional cylinder 7, two mounting plates 8, multiple racks 9, and multiple gears 10. The bidirectional cylinder 7 is fixedly connected to the upper surface of the L-shaped plate 2. The two mounting plates 8 are respectively fixedly connected to the two output ends of the bidirectional cylinder 7. Each rack 9 is symmetrically fixedly connected to one side of the mounting plate 8. Each gear 10 is fixedly sleeved on the rod wall of the corresponding rotating rod 5. Each rack 9 meshes with the corresponding gear 10.

[0029] Activating the bidirectional cylinder 7 allows the two mounting plates 8 to move, thereby allowing each rack 9 to move and drive the corresponding gear 10 to rotate, which in turn drives each rotating rod 5 to rotate.

[0030] To prevent the rotating rod 5 from rotating, such as Figure 1-3 As shown, each rotating rod 5 has a symmetrically fixedly connected limit strip 11 on its rod wall, and each through hole has a symmetrically opened limit groove on its inner wall. Each limit strip 11 is matched with the corresponding limit groove.

[0031] Each limiting bar 11 can play a limiting role during the upward movement of each rotating rod 5, thereby preventing the rotating rod 5 from rotating during the upward movement.

[0032] To facilitate the movement of strip block 6, such as Figure 1-4 As shown, the lower end of each strip 6 is conical.

[0033] Because the lower end of the strip block 6 is tapered, it facilitates the passage of each strip block 6 through the gap between the two bridge decks.

[0034] To prevent base 1 from tilting up, such as Figure 1-2 As shown, a counterweight 12 is fixedly connected to the upper surface of the base 1.

[0035] The counterweight 12 can be used to prevent the base 1 from tilting up when the device is in operation.

[0036] To prevent the bridge deck from slipping, such as Figure 4 As shown, each strip block 6 has anti-slip grooves on its upper surface.

[0037] Each anti-slip groove serves to prevent slippage and thus prevent the bridge deck from sliding off.

[0038] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
