Description

Technical Field

[0001] The invention relates to the technical field of mobile working platforms for bridge and culvert construction protection, and in particular to a mobile working platform for bridge and culvert construction protection in a plant protection area. Background Art

[0002] When road and bridge construction is being carried out in the wild protection area, between the bored pile foundation construction and the completion of the bridge pier construction, in order to protect the plants, the plant protection area generally sets up a mobile work platform in the work area. The workers carry out construction work on the bridge pier on the work platform to reduce damage to the plant protection area and protect the plant protection area to the greatest extent.

[0003] When the existing mobile work platform is in use, the work platform is generally supported by the ground through four wheels. The contact area between the work platform and the ground is small, so that the support stability of the work platform cannot be guaranteed. At the same time, when the existing work platform is in use, the parallel movement of the main hanging basket drives the steel cable to move through the motor, and the stability of the movement process of the main hanging basket cannot be guaranteed, which increases the safety risk of the workers on the main hanging basket. In addition, when the existing work platform stops working, the wheels of the work platform lack an effective limiting structure, which makes the work platform likely to move along the slope when encountering a slope, increasing the risk of construction operations. Therefore, a mobile work platform for bridge and culvert construction protection in a plant protection area is urgently needed to solve the existing problems. Summary of the invention

[0028] In this embodiment, sliding seats 9 are welded at both ends of the connecting beam 7, rollers 18 are installed inside the sliding seats 9, a limiting seat 10 is welded on the upper side of the sliding seat 9, and a hanging hole 22 is welded on the lower side of one end of the guide rail beam 8.

[0029] In this embodiment, a limiting groove 17 is machined on the limiting seat 10 , a hand chain hoist 11 is symmetrically mounted on one side of the connecting beam 7 , and a hook 27 is disposed at the lower end of the hand chain hoist 11 .

[0030] In this embodiment, a lifting ring 16 is connected to the lifting hook 27, a connecting rod 15 is welded to the lower side of the lifting ring 16, and a vertical pull rod 12 is connected to the upper side of the main hanging basket 14 by bolts.

[0031] In this embodiment, a limit rod 13 is welded to the upper end of the vertical pull rod 12 , and diagonal bracing rods 4 are welded to both side surfaces of the support column 3 .

[0032] In this embodiment, the upper end of the diagonal support rod 4 is welded to the guide rail crossbeam 8, both ends of the screw rod 6 are connected to the connecting member 28 through bearings, and the hand chain hoist 11 is connected to the connecting beam 7 through a hook lock.

[0033] In this embodiment, the lower end of the support column 3 is welded to the electric vehicle frame 1, one end of the support arm 24 is rotatably connected to the electric vehicle frame 1, and the housing of the jack 26 is connected to the support arm 24 by bolts.

[0034] In this embodiment, the telescopic rod of the jack 26 is connected to the support leg 25 via threads, the electric vehicle frame 1 has a built-in battery module, and the vertical pull rod 12 is connected to the limit seat 10 via the limit groove 17.

[0035] In this embodiment, the guide rail crossbeam 8 is an I-beam, and the connecting beam 7 is connected to the main hanging basket 14 through the hand winch 11.

[0036] Embodiment 2: Figure 7 As shown, the difference between this embodiment and the first embodiment is that the main hanging basket 14 and the side hanging basket 19 are installed on the upper end of the vertical pull rod 12 and are fixedly connected to the limit rod 13, so that the vertical pull rod 12 can move up and down under the adjustment of the hand winch 11, so that the main hanging basket 14 and the side hanging basket 19 can move up and down to carry out external construction work on the bridge piers at a higher position.

[0037] The operating principle of the mobile working platform of the present invention is as follows: when in operation, the electric frame 1 is moved to the bridge for operation, and the counterweight is hung on the hanging hole 22, or placed on the counterweight cargo plate 2 to ensure the force stability of the mobile working platform. Then, the support arm 24 on the lower side of the electric frame 1 is rotated out, and the support leg 25 is pressed against the ground by the jack 26, so that two wheels on one side of the electric frame 1 touch the ground, and the other side touches the ground through two support legs 25. Then, the wheels on the ground are clamped and fixed by the parking wedge 23 to prevent the wheels from moving on a sloping bridge. By adjusting the servo motor 5, the screw rod 6 is rotated, and then the connecting beam 7 is moved along the screw rod 6. The two ends of the connecting beam 7 move along the guide rail crossbeam 8 through the rollers 18 in the sliding seat 9. The main hanging basket 14 is moved to one side of the electric frame 1, and then the main hanging basket 14 is lowered by the hand winch 11. After being lowered, the construction workers can get on the main hanging basket 14, and then the workers lift the main hanging basket 14 by the hand winch 11, and then adjust the servo motor 5 by the control device, so that the connecting beam 7 moves along the screw rod 6 to the side away from the electric frame 1. When the distance between the main hanging basket 14 and the bridge meets the requirements, stop adjusting the servo motor 5, and then lower the main hanging basket 14 to the side of the bridge by the hand winch 11, so that the workers can construct the bridge conveniently. According to the construction requirements, the side hanging basket 19 can be hung on one side of the main hanging basket 14 by the hook 21 and the clamping plate 20, so that the construction workers can enter the side hanging basket 19 to carry out construction work on the lower side of the bridge.
