The supporting force of the bridge side helps to limit and stabilize the construction platform, counteracting the swaying caused by suspension descent and personnel movement.

Description

Technical Field

[0001] This utility model relates to the field of construction platform technology, specifically a construction platform for highway bridge engineering. Background Technology

[0002] Expressways, or highways for short, are multi-lane roads that are dedicated to the separate travel of automobiles in different directions and with fully controlled access. They are high-grade highways. Bridges are structures built to allow roads to cross natural or man-made obstacles. They are erected over rivers, lakes, and seas to enable vehicles and pedestrians to pass smoothly.

[0003] In existing technologies, when carrying out construction from the side of a highway, a construction platform is needed to help workers descend to a suitable position. The platform can provide a safe working space at height through its lifting mechanism, accurately locate the construction site with adjustable components, and enhance the stability of the platform with support devices, allowing personnel to conveniently and safely reach the target location to carry out repair work.

[0004] However, as the construction platform descends, it will move slightly during construction due to its suspended position. This movement will cause the platform's center of gravity to shift, resulting in swaying. This swaying reduces the precision of tool operation during construction and may even cause materials to fall. Therefore, we propose a construction platform for highway bridge engineering. Utility Model Content

[0005] One of the technical problems this application aims to solve is to limit the position of the construction platform after it is lowered, so as to avoid large-scale shaking caused by the movement of personnel.

[0006] To address the aforementioned technical problems, this application provides a highway bridge construction platform, including a fixing mechanism. A limiting mechanism is provided on the top side of the fixing mechanism. The fixing mechanism includes a construction platform, with a fixing plate on the inner wall of the platform. A rotating rod is located at the top of the fixing plate, rotatably connected to the bottom of the rotating rod. A connecting frame is located on one side of the rotating rod, rotatably connected to the inner side of one end of the connecting frame. An outer tube is located at one end of the connecting frame, fixedly connected to one end of the outer tube. An inner tube is located inside the outer tube, slidably connected to the outer side of the inner tube. A threaded rod is located on the inner wall of the inner tube, threadedly connected to the outer side of the threaded rod.

[0007] In some embodiments, the limiting mechanism includes a locking rod, an inner rod is provided on the inner side of one end of the locking rod, the inner side of one end of the locking rod is rotatably engaged with the outer side of the inner rod, an insertion rod is provided on one end of the inner rod, the inner side of the inner rod is fixedly connected to the inner side of the insertion rod, a side plate is provided at the bottom end of the locking rod, and the bottom end of the locking rod is rotatably connected to the top side of the side plate.

[0008] In some embodiments, a throttle is provided on the outer side of one end of the lead screw, and the outer side of one end of the lead screw is fixedly connected to the inner end of the throttle, and the end of the throttle is rotatably connected to the inner wall of the outer tube.

[0009] In some embodiments, a path plate is provided on one side of the construction platform, and one side of the construction platform is fixedly connected to one end of the path plate. A support seat is provided on the inner wall of the path plate, and the inner wall of the path plate is slidably connected to the bottom end of the support seat.

[0010] In some embodiments, the inner top side of the support base contacts the bottom side of the connecting frame.

[0011] In some embodiments, the top side of the construction platform is fixedly connected to the bottom end of the side plate.

[0012] In some embodiments, the inner wall of the side plate is slidably connected to the outer side of the insertion rod, and the bottom end of the insertion rod is vertically engaged with the top recess of the rotating rod.

[0013] In some embodiments, a rubber disc is provided at one end of the inner tube, and one end of the inner tube is fixedly connected to one side of the rubber disc.

[0014] This utility model has at least the following beneficial effects:

[0015] 1. By rotating the handle on the screw, the inner tube gradually slides out of the outer tube under the action of the thread and comes into contact with the side of the bridge. The supporting force of the bridge side can be used to limit and stabilize the construction platform. At the same time, a rubber disc is installed at one end of the inner tube. The rubber disc can increase the friction after contact with the bridge, which can further enhance the contact and stability between the inner tube and the side of the bridge. The supporting force of the bridge side can be used to limit and stabilize the construction platform, and counteract the shaking caused by the suspension descent and personnel movement.

[0016] 2. By placing the connecting rod inside the support base and the bottom of the support base in the semi-circular groove, when the position is limited from the side of the bridge, the support base can slide in the semi-circular groove by moving the connecting frame. In this way, the outer tube can be supported, avoiding the need to hold the outer tube to turn the handle during the rotation process, allowing the construction personnel to focus on turning the handle with one hand to adjust the inner tube extension and retraction.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1: Please refer to Figure 1 - Figure 6This utility model provides a technical solution: a construction platform for highway bridge engineering, including a fixing mechanism 1, a limiting mechanism 2 provided on the top side of the fixing mechanism 1, the fixing mechanism 1 including a construction platform 11, a fixing plate 12 provided on the inner wall of the construction platform 11, a rotating rod 13 provided on the top of the fixing plate 12, the top of the fixing plate 12 being rotatably connected to the bottom end of the rotating rod 13, a connecting frame 14 provided on one side of the rotating rod 13, the one side of the rotating rod 13 being rotatably connected to the inner side of one end of the connecting frame 14, an outer tube 15 provided on one end of the connecting frame 14, one end of the connecting frame 14 being fixedly connected to one end of the outer tube 15, an inner tube 16 provided inside the outer tube 15, the inside of the outer tube 15 being slidably connected to the outside of the inner tube 16, a threaded rod 19 provided on the inner wall of the inner tube 16, the inner wall of the inner tube 16 being threadedly connected to the outside of the threaded rod 19, the threaded rod 19... One end of the outer side is provided with a handle 18, and one end of the lead screw 19 is fixedly connected to the inner end of the handle 18. One end of the handle 18 is fitted and rotatedly connected to the inner wall of the outer tube 15. One side of the construction platform 11 is provided with a path plate 110, and one side of the construction platform 11 is fixedly connected to one end of the path plate 110. The inner wall of the path plate 110 is provided with a support seat 111, and the inner wall of the path plate 110 is slidably connected to the bottom end of the support seat 111. The inner side of the top of the support seat 111 contacts the bottom side of the connecting frame 14. The top side of the construction platform 11 is fixedly connected to the bottom end of the side plate 112. The inner wall of the side plate 112 is slidably connected to the outer side of the insertion rod 113. The bottom end of the insertion rod 113 is vertically engaged with the top recess of the rotating rod 13. One end of the inner tube 16 is provided with a rubber disc 17, and one end of the inner tube 16 is fixedly connected to one side of the rubber disc 17.

[0027] When using this type of highway bridge construction platform, firstly, during the construction and repair of the side of the bridge, as the lifting platform continuously lowers the construction platform 11, the platform 11 may sway due to its suspended descent and the movement of personnel. Therefore, a fixed plate 12 is designed on the inner wall of one side of the construction platform 11, and a rotating rod 13 is installed at the center of the fixed plate 12. Both can rotate 360 ​​degrees. A connecting frame 14 is designed at the top of the rotating rod 13, which can rotate 180 degrees left and right on the rotating rod 13. An outer tube 15 is installed at one end of the connecting frame 14. An inner tube 16 is designed inside the outer tube 15. The inner tube 16 can slide inside the outer tube 15, so that the inner tube 16 gradually slides out from the outer tube 15. A screw rod 19 is installed inside the inner tube 16. Therefore, by rotating the handle 18 on the screw rod 19, the inner tube 16 gradually slides out from the outer tube 15 under the action of the thread and comes into contact with the side of the bridge. The supporting force of the side of the bridge can be used to limit and stabilize the construction platform 11, and counteract the shaking caused by the suspension descent and personnel movement.

[0028] A path plate 110 is designed on one side of the construction platform 11. A semi-circular groove is opened in the path plate 110. By placing the connecting rod inside the support seat 111 and the bottom end of the support seat 111 in the semi-circular groove, when the position is limited from the side of the bridge, the support seat 111 slides in the semi-circular groove by moving the connecting frame 14. In this way, the outer tube 15 can be supported, avoiding the need to hold the outer tube 15 to rotate the handle 18 during the rotation process. This allows the construction personnel to focus on rotating the handle 18 with one hand to adjust the extension and retraction of the inner tube 16.

[0029] Before the connecting frame 14 is moved, a side plate 112 is designed on the top side of the construction platform 11, and an insert rod 113 is designed on the inner wall of one end of the side plate 112. The bottom end of the insert rod 113 is equipped with a cube. Therefore, by pulling the insert rod 113 upward, the cube is disengaged from the connecting frame 14, thereby releasing the limit on the connecting frame 14. When not in use, the connecting frame 14 can be prevented from rotating randomly due to shaking or accidental contact by personnel, thereby preventing the connecting frame 14, outer tube 15 and other components from being accidentally displaced.

[0030] Example 2: Please refer to Figure 2 - Figure 6 The limiting mechanism 2 includes a locking rod 21, an inner rod 22 is provided on the inner side of one end of the locking rod 21, and the inner side of one end of the locking rod 21 is rotatably engaged with the outer side of the inner rod 22. An insertion rod 113 is provided on one end of the inner rod 22, and the inner side of the inner rod 22 is fixedly connected to the inner side of the insertion rod 113. A side plate 112 is provided at the bottom end of the locking rod 21, and the bottom end of the locking rod 21 is rotatably connected to the top side of the side plate 112.

[0031] A locking rod 21 is installed at the top of the side plate 112. One end of the locking rod 21 has a mating opening with the same diameter as the inner rod 22. The inner rod 22 is fixed in the insert rod 113. When the insert rod 113 is pulled up, the locking rod 21 is moved so that the mating opening on the locking rod 21 engages with the inner rod 22, thereby limiting the position of the insert rod 113 and preventing the insert rod 113 from interfering with the angle adjustment of the connecting frame 14 due to gravity. This ensures the smoothness of the connecting frame 14's movement and allows construction personnel to adjust the angle of the connecting frame 14 without hindrance according to the bridge's side structure. Finally, by applying external force to the locking rod 21, the locking rod 21 is disengaged from the inner rod 22, thereby releasing the restriction on the insert rod 113.

[0032] Please see Figure 1 - Figure 6When constructing and repairing the side of the bridge, after the construction platform 11 is lowered to a certain extent, the handle 18 on the screw rod 19 is rotated, causing the inner tube 16 to gradually slide out from the outer tube 15 under the action of the thread and come into contact with the side of the bridge. The supporting force of the bridge side can be used to limit and stabilize the construction platform 11. At the same time, a rubber disc 17 is installed at one end of the inner tube 16. The rubber disc 17 can increase the friction after contact with the bridge, which can further enhance the stability of the inner tube 16 in contact with the bridge side. Secondly, by placing the connecting rod inside the support seat 111, the bottom end of the support seat 111 is located in the semi-circular groove. When the position is limited from the side of the bridge, the connecting frame 14 is moved, causing the support seat 111 to slide in the semi-circular groove. In this way, the outer tube 15 can be supported, avoiding the need to hold the outer tube 15 to rotate the handle 18 during the rotation process.

[0033] By moving the locking rod 21, the engaging port on the locking rod 21 engages with the inner rod 22, thereby limiting the position of the insert rod 113. This prevents the insert rod 113 from interfering with the angle adjustment of the connecting frame 14 due to gravity, thus ensuring the smooth operation of the connecting frame 14 and allowing construction personnel to adjust the angle of the connecting frame 14 without hindrance according to the side structure of the bridge.
