Description

Technical Field

[0001] The utility model relates to the field of Bailey plates, and more specifically, to a Bailey plate transportation device with a limiting function. Background Art

[0002] As an assembled steel bridge component widely used in engineering fields such as bridge construction and temporary road construction, Bailey plates have the advantages of rapid assembly and strong adaptability. During the use of Bailey plates, it is crucial to transport them safely and efficiently.

[0003] Currently, during the processing of Bailey plates, when they need to be transferred between different production lines, they are generally transported by a handcart. The handcart has no limiting and fixing device. During transportation, when encountering bumps, turns, etc., the Bailey plates are prone to displacement and slipping, which will not only damage the Bailey plates themselves, affecting their subsequent use performance and service life, but also pose serious safety hazards (hitting the staff).

[0004] Therefore, in order to solve the above technical problems, this application proposes a Bailey plate transportation device with a limiting function. Content of the Utility Model

[0005] Aiming at the deficiencies of the prior art, the purpose of the utility model is to provide a Bailey plate transportation device with a limiting function.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A Bailey plate transportation device with a limiting function, including a moving platform for transporting the Bailey plates, on which a push rod is arranged. It is characterized in that: A reinforcing rod is fixedly connected to the middle of the push rod. The Bailey plate transportation device with a limiting function further includes:

[0007] An elastic pressure assembly, which is arranged directly above the moving platform, and squeezes and limits the topmost Bailey plate through the elasticity formed by the internal spring thereof; The pressure on the Bailey plate is adjusted by controlling the compression degree of the spring;

[0008] A lifting component, which is installed in the middle of the reinforcing rod and is used to drive the up and down movement of the elastic pressure assembly.

[0009] Preferably, the lifting component is an electro-hydraulic rod, and its head is connected to the side end of the elastic pressure assembly through a cross plate.

[0011] Preferably, a rubber pad is bonded to the bottom end of the lower pressing plate to avoid damaging the Bailey truss.

[0012] Preferably, on both sides of the top end of the connecting plate, there are indicating rods fixedly connected. On both sides of the top end of the hollow housing, there are through slots A for the indicating rods to pass through, which is convenient for the staff to understand the compression degree of the spring.

[0013] Preferably, a protrusion for limiting the bottommost Bailey truss is installed on the top end of the moving platform to avoid misalignment of the Bailey stack.

[0014] Preferably, the reinforcing rod and the lifting component are detachably connected, enabling the disassembly and assembly of the elastic pressure assembly and the lifting component.

Detailed Embodiment

[0027] As Figures 1-4 shown, the present utility model provides a Bailey truss transportation device with a limiting function, including a mobile platform 1 for transporting the Bailey truss, on which a push rod 2 is arranged, and a reinforcing rod 18 is fixedly connected to the middle of the push rod 2. The Bailey truss transportation device with a limiting function further includes:

[0028] An elastic pressure component 3, which is arranged directly above the mobile platform 1 and presses and limits the topmost Bailey truss through the elasticity formed by the internal spring 31 therein; the pressure on the Bailey truss is adjusted by controlling the compression degree of the spring 31;

[0029] The lifting component 4 is installed in the middle of the reinforcing rod 18 and is used to drive the up and down movement of the elastic pressure component 3. At the same time, the reinforcing rod 18 can also reinforce the overall structure of the push rod 2.

[0030] During use, stack multiple Bailey plates on the moving platform 1 of the trolley. A protrusion 17 can be provided on the top of the moving platform 1 to facilitate the staff to find the placement position of the bottommost Bailey plate. The subsequent Bailey plates are flush with the bottommost Bailey plate (if the stacking position is offset too much, it will affect the later limiting effect on the Bailey plates). Then, drive the elastic pressure component 3 to move downward through the lifting component 4. The elastic pressure component 3 squeezes the topmost Bailey plate downward. Adjust the pressure on the Bailey plate by controlling the compression degree of the spring 31, so as to firmly limit the Bailey plate and avoid damaging the Bailey plate at the same time. The lifting component 4 is preferably an electric hydraulic rod, and its head is connected to the side end of the elastic pressure component 3 through a cross plate 5. Control the lifting of the electric hydraulic rod through a controller.

[0031] As a further improvement, the reinforcing rod 18 and the lifting component 4 are detachably connected, so that the pressure elastic component and the lifting component 4 can be installed as needed to avoid unnecessary waste (for example, in places without bumps and for short-distance movement). The following is the specific detachable structure: An upper open groove seat 6 is fixedly connected between the reinforcing rods 18. The bottom end of the lifting component 4 is fixedly connected with a connecting block 7 that can be inserted into the upper open groove seat 6. A through groove B8 is opened on the surface of the upper open groove seat 6. A groove 9 is opened on the surface of the connecting block 7. Guide rails B10 for the sliding of slider B11 are fixedly connected to both sides of the bottom end of the upper open groove seat 6. The surface of the slider B11 is fixed to a vertical plate 13 through a connecting rod 12. A convex block 14 is fixedly connected to the middle part of the surface of the vertical plate 13. Screws 15 are fixedly connected to both sides of the surface of the upper open groove seat 6 where the through groove B8 is located. Through holes 16 for the screws 15 to pass through are opened on both sides of the surface of the upper open groove seat 6 where the convex block 14 is located.

[0032] First, insert the connecting block 7 at the bottom of the lifting component 4 into the upper opening groove seat 6 on the upper reinforcing rod 18 for limiting. After the insertion is completed, the groove 9, the through groove B8, and the convex block 14 are exactly on the same horizontal line. Then, push the vertical plate 13 to move towards the upper opening groove seat 6. The upper opening groove seat 6 drives the movement of the slider B11 through the connecting rod 12, and the slider B11 slides along the guide rail B10 to maintain the linear movement of the vertical plate 13. The vertical plate 13 can linearly drive the connecting block 7 to move towards the upper opening groove seat 6, so that the connecting block 7 passes through the through groove B8 and is inserted into the groove 9 on the connecting block 7, making the vertical plate 13 closely adhere to the surface of the upper opening groove seat 6. At the same time, the through hole 16 on the vertical plate 13 also passes through the screw rod 15 on the upper opening groove seat 6. Then, rotate the nut clockwise to install the nut on the screw rod 15. The nut moves along the screw rod 15 and slowly presses against the back surface of the vertical plate 13 to fix the position of the convex block 14, thereby fixing the connecting block 7 in the upper opening groove seat 6, and completing the installation of the elastic pressure component 3 and the lifting component 4. Conversely, remove the nut, pull out the convex block 14 from the groove 9 and the through groove B8, and then pull out the connecting block 7 from the upper opening groove seat 6 to realize the disassembly of the elastic pressure component 3 and the lifting component 4. The operation is relatively simple.

[0033] The present utility model also provides the specific structure of the elastic pressure component 3: The elastic pressure component 3 includes a hollow shell 32 fixed to the side end of the cross plate 5. On both sides inside the hollow shell 32, guide rails A33 for the slider A34 to slide are fixedly connected. A connecting plate 35 is fixedly connected between the sliders A34. A spring 31 is installed between the top of the connecting plate 35 and the inner top wall of the hollow shell 32. The bottom end of the connecting plate 35 is fixedly connected with a vertical rod 37 passing through the bottom of the hollow shell 32. The end of the vertical rod 37 is fixedly connected with a lower pressing plate 38. When the lifting component 4 drives the elastic pressure component 3 to move downward, the lower pressing plate 38 thereon will first contact the topmost layer of the Bailey sheet. When moving further downward, since the lower pressing plate 38 is blocked by the Bailey sheet, it will drive the connecting plate 35 to move upward along the hollow shell 32 through the vertical rod 37. The connecting plate 35 drives the movement of the slider A34, and the slider A34 slides along the guide rail A33 to maintain the linear movement of the connecting plate 35, and at the same time compresses the spring 31. By controlling the compression degree of the spring 31, the pressure of the lower pressing plate 38 on the Bailey sheet is adjusted. It is preferably to bond a rubber pad 39 to the bottom end of the lower pressing plate 38. The rubber pad 39 has a certain elasticity and can, to a certain extent, prevent the lower pressing plate 38 from directly contacting the Bailey sheet and damaging the Bailey sheet (more comprehensively protecting the Bailey sheet).

[0034] Furthermore, indicator rods 310 are fixedly connected to both sides of the top end of the connecting plate 35. Through slots A36 for the indicator rods 310 to pass through are formed in both sides of the top end of the hollow housing 32. When the connecting plate 35 moves upward relative to the hollow housing 32 and the spring 31 is compressed, the indicator rods 310 also gradually extend out of the hollow housing 32 through the through slots A36. The staff can adjust the compression degree of the spring 31 according to the length of the extended indicator rods 310, so as to adjust the limiting pressure on the Bailey truss. The reason for this design is that the height of the hollow housing 32 is relatively high and there is no other component blocking it, which is convenient for the staff to view. Different colors can be painted at different heights of the indicator rods 310, thereby improving the eye-catching effect.

[0035] The above are only the preferred embodiments of the present invention, and do not impose any form of limitation on the present invention; any ordinary technical personnel in this industry can smoothly implement the present invention as shown in the accompanying drawings of the specification and described above; however, any minor changes, modifications and equivalent changes made by those familiar with the technology in the technical scope of the present invention without departing from the technical solution of the present invention by using the technical content disclosed above are all equivalent embodiments of the present invention; at the same time, any equivalent changes, modifications and evolutions made to the above embodiments based on the essential technology of the present invention still fall within the protection scope of the technical solution of the present invention.
