Description

Technical Field

[0001] The utility model relates to the technical field of construction equipment, in particular to a temporary construction bridge slab. Background Art

[0002] On the construction site, workers usually erect temporary bridge slabs to cross the gully or obstacle sections in the construction site.

[0003] However, the existing temporary bridge slabs are usually made of a whole iron plate or wooden board. The length of the bridge slab often needs to be designed according to the length of the obstacle section, and it is difficult for the same specification of bridge slab to adapt to the obstacle sections with different lengths. When the length of the bridge slab is shorter than the length of the obstacle section, the bridge slab is difficult to play a role. When the length of the bridge slab is longer than the length of the obstacle section, it is difficult to carry and erect the bridge slab due to its excessive length, increasing the labor intensity of workers and having poor applicability. Therefore, this application specifically proposes a temporary construction bridge slab that can adjust the length of the bridge slab according to the length of the obstacle section. Summary of the Utility Model

[0004] The main purpose of the utility model is to provide a temporary construction bridge slab that can adjust the length of the bridge slab according to the length of the obstacle section.

[0005] To achieve the above purpose, the utility model provides a temporary construction bridge slab, including:

[0006] A positioning plate, in which a chamber is provided, and one end of the chamber is provided with an opening communicating with the external environment;

[0007] A telescopic component, including a multi-stage telescopic assembly arranged in the positioning plate. The multi-stage telescopic assembly includes a plurality of sliding plates slidably sleeved in sequence along the length direction of the positioning plate. The outermost sliding plate in the multi-stage telescopic assembly is the active sliding plate, and the remaining sliding plates are driven sliding plates. The active sliding plate is slidably arranged in the chamber;

[0008] A transmission component, arranged on the corresponding sliding plates. When the active sliding plate moves in the chamber, the transmission component is used to drive each driven sliding plate to move away from or close to the positioning plate together;

[0009] A driving component, arranged in the chamber, and one end of the driving component is connected to the active sliding plate. The driving component is used to drive the active sliding plate to reciprocate along the length direction of the positioning plate in the chamber.

[0010] Further, the transmission component includes two first gears respectively rotatably arranged on both sides of the active slide plate. On one side of each first gear, there is a rack group. The rack group includes a first rack arranged on the corresponding side of the chamber, and another first rack arranged on the driven slide plate slidably connected to the active slide plate.

On both sides of each driven slide plate, a second gear is also rotatably arranged, and on both sides of the two slide plates adjacent to the driven slide plate, there are second racks meshing with the corresponding second gears. When the active slide plate moves away from the positioning plate, each first gear cooperates with the first rack to drive the corresponding driven slide plate to move away from the positioning plate, and each second gear cooperates with the second rack to drive the corresponding driven slide plate to move away from the positioning plate.

[0011] Further, each slide plate is provided with a third through hole, and in the innermost driven slide plate of the multi-stage telescopic component, there is a notch corresponding to and concentrically arranged with each third through hole;

The threaded rod is arranged along the length direction of the positioning plate, and the diameter of the threaded rod corresponds to and is concentrically arranged with the aperture of each third through hole. A connecting block is screwed on the threaded rod, and one end of the connecting block is connected to the active slide plate. When the threaded rod rotates, the threaded rod drives the active slide plate to reciprocate along the length direction of the positioning plate in the chamber through the connecting block.

[0013] Further, the innermost driven slide plate of the multi-stage telescopic component is a support plate. The support plate is provided with a first through hole, and an internal thread is provided in the first through hole. At the bottom of the support plate, there is also a chute, and the chute is communicated with the first through hole. At one end of the support plate away from the positioning plate, there is also a second through hole, and an internal thread is provided in the second through hole;

[0014] The support plate is provided with a positioning component. The positioning component includes an abutting plate vertically slidably arranged in the chute. Above the abutting plate, there is a transmission rod rotatably arranged. The transmission rod is provided with an external thread and is screwed in the first through hole. When the transmission rod rotates, the transmission rod is used to drive the abutting plate to move vertically back and forth. In the second through hole, there is also a positioning cone vertically slidably arranged. The positioning cone is provided with an external thread and is screwed with the second through hole. When the positioning cone rotates, the positioning cone moves vertically back and forth in the second through hole.

[0015] Furthermore, a moving component is also provided on the positioning plate. The moving component includes a roller rotatably provided at one end of the positioning plate away from the transmission component, and a handle is also rotatably provided on the positioning plate.

[0016] The beneficial effects of the present utility model are embodied in:

[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Without conflict, the embodiments in this application and the features in the embodiments can be combined with each other.

[0028] See Figures 1-7 .

[0029] The present invention discloses a temporary construction bridge slab, including:

[0030] A positioning plate 1, in which a chamber 11 is provided, and an opening communicating with the external environment is provided at one end of the chamber 11;

[0031] A telescopic component 2, including a multi-stage telescopic assembly 21 provided in the positioning plate 1. The multi-stage telescopic assembly 21 includes a plurality of slide plates slidably sleeved in sequence along the length direction of the positioning plate 1. The outermost slide plate in the multi-stage telescopic assembly 21 is an active slide plate 211, and the remaining slide plates are driven slide plates 212. The active slide plate 211 is slidably provided in the chamber 11;

[0032] A transmission component 3 is provided on the corresponding slide plate. When the active slide plate 211 moves in the chamber 11, the transmission component 3 is used to drive each driven slide plate 212 to move away from or close to the positioning plate 1 together;

[0033] A driving component 4 is provided in the chamber 11, and one end of the driving component 4 is connected to the active slide plate 211. The driving component 4 is used to drive the active slide plate 211 to reciprocate along the length direction of the positioning plate 1 in the chamber 11.

[0034] In specific implementation, when it is necessary to erect the bridging plate, first move the positioning plate 1 to one side of the obstacle section, and align the opening of the positioning plate 1 with the obstacle section. Then, drive the active slide plate 211 to extend out of the positioning plate 1 through the driving component 4. At this time, the transmission component 3 drives each driven slide plate 212 to move away from the positioning plate 1 together until the innermost driven slide plate 212 in the multi-stage telescopic assembly 21 moves to the other side of the obstacle section. At this time, the driving component 4 stops working, and the multi-stage telescopic assembly 21 is erected. When it is necessary to remove the bridging plate, drive the active slide plate 211 to contract into the positioning plate 1 through the driving component 4. At this time, the transmission component 3 drives each driven slide plate 212 to move closer to the positioning plate 1 until the multi-stage telescopic assembly 21 moves into the chamber 11.

[0035] In the present utility model, when the driving component 4 drives the active slide plate 211 to move, through the cooperation of the telescopic component 2 and the transmission component 3, each driven slide plate 212 moves together until the corresponding driven slide plate 212 is erected on the corresponding end of the obstacle section, so that the overall length of the multi-stage telescopic assembly 21 can be adjusted according to the actual length of the obstacle section, improving the applicability. When the bridging plate is no longer used, the multi-stage telescopic assembly 21 is contracted into the positioning plate 1, thereby shortening the overall length of the bridging plate, facilitating handling, and reducing the labor intensity of the staff.

[0036] In an embodiment, the transmission component 3 includes two first gears 32 respectively rotatably provided on both sides of the active slide plate 211. One side of each first gear 32 is provided with a rack group. The rack group includes a first rack 31 provided on the corresponding side of the chamber 11, and another first rack 31 provided on the driven slide plate 212 slidably connected to the active slide plate 211. The two first racks 31 are respectively provided on both sides of the corresponding first gear 32 and mesh with the corresponding first gear 32. Second gears 33 are respectively rotatably provided on both sides of each driven slide plate 212, and second racks 34 meshing with the corresponding second gears 33 are provided on both sides of the two slide plates adjacent to the driven slide plate 212. When the active slide plate 211 moves away from the positioning plate 1, each first gear 32 cooperates with the first rack 31 to drive the corresponding driven slide plate 212 to move away from the positioning plate 1, and each second gear 33 cooperates with the second rack 34 to drive the corresponding driven slide plate 212 to move away from the positioning plate 1.

[0037] With this design, when it is necessary to set up the bridging plate, the driving component 4 drives the active sliding plate 211 to move away from the positioning plate 1. Each first gear 32 moves together with the active sliding plate 211 and meshes with the corresponding first rack 31, thereby driving the driven sliding plate 212 slidably arranged on the active sliding plate 211 to move away from the positioning plate 1 together. Furthermore, through the engagement of the second gear 33 on the driven sliding plate 212 with the second rack 34 on the corresponding other driven sliding plate 212, the corresponding driven sliding plate 212 is driven to move away from the positioning plate 1, so as to extend the multi-stage telescopic assembly 21 until the innermost driven sliding plate 212 in the multi-stage telescopic assembly 21 moves to the predetermined position. When it is no longer necessary to set up the bridging plate, the driving component 4 drives the active sliding plate 211 to move towards the positioning plate 1. Each first gear 32 meshes with the corresponding first rack 31, and each second gear 33 meshes with the corresponding second rack 34, and drives each driven sliding plate 212 to move towards the positioning plate 1 until each driven sliding plate 212 contracts into the chamber 11.

[0038] In one embodiment, a third through hole 22 is formed in each sliding plate, and a notch 23 corresponding to and concentric with each third through hole 22 is formed in the innermost driven sliding plate 212 in the multi-stage telescopic assembly 21;

[0039] The driving component 4 includes a power unit 41 arranged in the chamber 11. A threaded rod 42 is provided on the moving end of the power unit 41. The threaded rod 42 is arranged along the length direction of the positioning plate 1, and the diameter of the threaded rod 42 corresponds to and is concentric with the aperture of each third through hole 22. A connecting block 43 is screwed on the threaded rod 42. One end of the connecting block 43 is connected to the active sliding plate 211. When the threaded rod 42 rotates, the threaded rod 42 drives the active sliding plate 211 to reciprocate along the length direction of the positioning plate 1 in the chamber 11 through the connecting block 43.

[0040] With this design, when it is necessary to cross an obstacle section, the power unit 41 rotates the threaded rod 42, so that the threaded rod 42 drives the active sliding plate 211 to move away from the length direction of the positioning plate 1 through the connecting block 43. Since the active sliding plate 211 is slidably arranged in the chamber 11, the active sliding plate 211 prevents the connecting block 43 from rotating together with the threaded rod 42. Then, through the transmission component 3, each driven sliding plate 212 is driven to move away from the positioning plate 1 together until the corresponding driven sliding plate 212 is erected on the corresponding end of the obstacle section. When it is no longer necessary to cross the obstacle section, the power unit 41 reversely rotates the threaded rod 42, and the active sliding plate 211 contracts into the chamber 11. The transmission component 3 drives each driven sliding plate 212 to move towards the positioning plate 1 until the multi-stage telescopic assembly 21 contracts into the chamber 11. At this time, the threaded rod 42 passes through each third through hole 22 and is inserted into the notch 23.

[0041] In one embodiment, the innermost driven sliding plate 212 in the multi-stage telescopic assembly 21 is a support plate 213. A first through hole 2131 is formed in the support plate 213, and an internal thread is provided in the first through hole 2131. A chute 2132 is further provided at the bottom of the support plate 213, and the chute 2132 communicates with the first through hole 2131. A second through hole 2133 is also formed at one end of the support plate 213 away from the positioning plate 1, and an internal thread is provided in the second through hole 2133.

[0042] A positioning component 5 is provided on the support plate 213. The positioning component 5 includes an abutting plate 51 vertically slidably arranged in the chute 2132. A transmission rod 52 is rotatably provided above the abutting plate 51. An external thread is provided on the transmission rod 52 and is screwed into the first through hole 2131. When the transmission rod 52 rotates, the transmission rod 52 is used to drive the abutting plate 51 to move vertically in a reciprocating manner. A positioning cone 53 is also vertically slidably arranged in the second through hole 2133. An external thread is provided on the positioning cone 53 and is screwed with the second through hole 2133. When the positioning cone 53 rotates, the positioning cone 53 moves vertically in a reciprocating manner in the second through hole 2133.

[0043] With this design, when the support plate 213 moves to one end corresponding to the obstacle section, since there is a height difference between the bottom surface of the support plate 213 and the bottom surface of the positioning plate 1, at this time, the bottom surface of the support plate 213 does not contact the ground. The staff rotates the transmission rod 52 and drives the abutting plate 51 to move downward until the abutting surface of the abutting plate 51 contacts the ground, so as to support the support plate 213. When the obstacle section is a soft ground such as mud, the staff can also rotate the positioning cone 53 to make the positioning cone 53 move downward until the positioning cone 53 is inserted into the road surface, so as to further support and position the support plate 213 and prevent the support plate 213 from moving accidentally.

[0044] It should be noted that the abutting surface of the abutting plate 51 can be made into a friction surface feature with a high friction coefficient, so as to increase the friction force between the abutting plate 51 and the ground and further improve the stability of the support plate 213.

[0045] In one embodiment, a moving component 6 is further provided on the positioning plate 1. The moving component 6 includes a roller 61 rotatably provided at one end of the positioning plate 1 away from the transmission component 3, and a handle 62 is also rotatably provided on the positioning plate 1.

[0046] With this design, when the positioning plate 1 needs to be retracted, the positioning plate 1 is erected to make the roller 61 contact the ground, and then the positioning plate 1 is pulled through the handle 62, so as to facilitate the manual movement of the positioning plate 1.

[0047] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model. In addition, "a plurality of", "multiple groups", and "several" mean more than two.
