[0002] A diaphragm construction platform is a specialized platform used for constructing diaphragms (such as floor slabs and roof panels) in construction projects. Its primary function is to provide a safe and stable working environment for construction workers to perform operations such as concrete pouring and rebar tying.

[0003] During the existing diaphragm construction operation at the construction site, the operating platform is hoisted to the wet joints of the viaduct for use. The platform is heavy, unstable, and lacks safety protection, resulting in an insufficient safety level in use. In this regard, a foldable diaphragm operating platform is proposed to solve the above problems. Utility Model Content

[0023] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0024] See also Figures 1 to 5 In this embodiment, a foldable diaphragm operating platform includes a mobile vehicle 1 located on the wet joint 3 of the viaduct. An operating platform 2 is provided on the mobile vehicle 1. The mobile vehicle 1 is provided with a hydraulic folding system for controlling the folding of the operating platform 2 and a lifting system for controlling the lifting of the operating platform 2, so that the operating platform 2 can be moved by the mobile vehicle 1 and has the function of folding and lifting. Compared with the existing hanging operating platform, it is more convenient and safer to use.

[0025] In this embodiment, the mobile vehicle 1 is located in the middle of the viaduct wet joint 3 to ensure that the midpoint of the operating platform 2 is consistent with the center line of the viaduct wet joint.

[0026] It should be noted that the operating platform 2 includes four square tubes 21 and folding rods 24 and cross bars 25 connected to the square tubes 21, wherein the cross bars 25 are located between the two groups of square tubes 21 on the left and right sides and are parallel to each other. Specifically, the interval between adjacent cross bars 25 is 0.2-0.3 meters.

[0027] The square tube 21 is a galvanized tube with a side length of 2 cm and is connected by welding.

[0028] This arrangement, on the one hand, can provide safety protection on both sides through the cross bar 25, and on the other hand can provide a ladder-like structure for the operator to climb out of the operating platform 2 later.

[0029] Furthermore, the length of the folding rod 24 is half the length of the cross bar 25 and is divided into two sections. The folding rods 24 at both ends are hinged by a hinge shaft 4. Further, several hinge shafts 4 are connected to an adjustment rod 23, and the adjustment rod 23 is parallel to the four square tubes 21.

[0030] In a specific implementation, the adjusting rod 23 drives several hinge shafts 4 to move in the vertical direction, so that several folding rods 24 can be bent, so that the two groups of square tubes 21 on both sides are close to each other, and the folding of the operating platform 2 is completed.

[0031] It is additionally noted that a flat plate 22 is hingedly connected to the top end of the square tube 21 , and the flat plate 22 extends outward from the square tube 21 . A bottom flat plate is hingedly connected to the bottom end of the square tube 21 for providing a support surface.

[0032] It is understandable that an axle pin hole 5 is formed through the folding rod 24 , and the axle pin hole 5 is passed through to realize the bending and locking of the folding rod 24 , thereby ensuring that the operating platform 2 is fixed after being unfolded and formed.

[0033] In order to control the operating platform 2 to unfold toward both sides, the hydraulic folding system in this embodiment includes a hydraulic cylinder 6 fixedly installed in the mobile vehicle 1. The hydraulic cylinder 6 includes two groups symmetrically installed on the mobile vehicle 1. The two hydraulic cylinders 6 are controlled simultaneously to realize the folding or unfolding of the pulling operating platform 2.

[0034] In this embodiment, the hydraulic folding system further includes a connecting frame 7 fixedly mounted on the telescopic end of the hydraulic cylinder 6 , and support frames 9 located on the square tube 21 are fixedly mounted on both the left and right side surfaces of the operating platform 2 .

[0035] Specifically, the support frame 9 is bent in an L-shape, and the connecting frame 7 has a bent plate 8 integrally extending toward the vertical end of the support frame 9, so that the mutual connection between the support frame 9 and the connecting frame 7 is stable and can achieve vertical sliding, so that the hydraulic folding system can not interfere with the operation of the lifting system.

[0036] It should be noted that the lifting system includes a mounting plate 11 slidably mounted on the top of the mobile vehicle 1 , a servo motor 13 fixedly mounted on the mounting plate 11 , and a transmission member connected between the servo motor 13 and the operating platform 2 .

[0037] Preferably, a guide rail 12 is fixedly installed on the top of the mobile vehicle 1, and the mounting plate 11 slides in contact with the guide rail 12. The guide rail 12 can improve the accuracy of the movable position of the mounting plate 11 relative to the mobile vehicle 1.

[0038] Furthermore, a traction rod 10 is fixedly connected between the bottom of the mounting plate 11 and the top of the connecting frame 7. Through the connection of the traction rod 10, the mounting plate 11 can change its position synchronously with the movement of the hydraulic folding system.

[0039] The transmission parts in this embodiment include a gear rack 15 fixedly connected to the middle of several cross bars 25, a rack 16 fixedly installed inside the gear rack 15, and a driving wheel 14 fixedly installed on the power end of the servo motor 13. The driving wheel 14 is attached to the gear rack 15 and engages with the rack 16.

[0040] In a specific implementation, by controlling the servo motor 13 , the operating platform 2 can be driven to move up and down by gear engagement.

[0041] The working principle of the above embodiment is:

[0042] When the platform 2 is lowered to the upper end of the platform 2, the platform 2 is moved downwards, and the platform 2 is moved downwards, so that the platform 2 is lifted up and the workbench 2 is lifted and the workbench 2 is lifted.

[0043] After use, adjust the lifting system and raise the operating platform 2 until the crossbar 25 is flush with the box girder flange plate. The operator climbs out of the platform and operates the hydraulic folding system to fold the personnel operating platform. Finally, operate the lifting system to lift the personnel operating platform to the highest point.
