Description

Technical Field

[0001] This utility model relates to the field of bridge construction equipment technology, specifically to a suspended platform device for bridge maintenance and construction. Background Technology

[0002] The maintenance and repair of urban pedestrian bridges is generally carried out using a hanging basket device. The hanging basket device is hung on the side walls or railings on both sides of the bridge, which makes it convenient for maintenance personnel to inspect the outside of the bridge.

[0003] A Chinese patent document with publication number CN112359731B discloses a movable hanging basket device for use on concrete tie rods of a tied-arch bridge. The device includes a traveling support and a working platform mounted on the traveling support. In use, the traveling support is hung on the tie rod on the side of the bridge, and its position for maintenance is changed by moving along the tie rod via rollers. The shortcomings of this movable hanging basket device are: the size of the traveling support is basically fixed and difficult to adjust; when encountering obstacles while moving along the tie rod, it needs to be disassembled, moved over the obstacle, and then reattached to the tie rod, which is time-consuming, labor-intensive, and affects work efficiency.

[0004] Chinese Patent CN217579810U discloses a movable prefabricated hanging basket device for bridge maintenance construction. It includes a traveling trolley located on the inner side of the bridge deck of a crash barrier, a vertical beam frame located on the outer side of the crash barrier, and a horizontal beam frame connecting the traveling trolley and the top of the vertical beam frame. The horizontal beam frame is detachably connected to the vertical beam frame and the traveling trolley. A hanging basket is mounted on the vertical beam frame, and a counterweight plate is connected to the traveling trolley, which supports the placement of counterweights. The drawback of this movable hanging basket device is that when encountering obstacles while moving along the crash barrier, it needs to be disassembled, moved over the obstacle, and then reattached to the crash barrier, which is time-consuming, labor-intensive, and affects work efficiency. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the existing technology and provide a bridge maintenance and construction suspended platform device that is convenient for crossing obstacles, saves time and effort, and improves work efficiency.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] A suspended platform device for bridge maintenance and construction includes an operating platform, a hanging frame, and a traveling mechanism. The top of the hanging frame is rotatably connected to the traveling mechanism and forms a hanging interval between them. The operating platform is located at the bottom of the hanging frame, and the traveling mechanism is equipped with a flipping drive mechanism for flipping the hanging frame to change the size of the hanging interval.

[0008] As a further improvement to the above technical solution:

[0009] The flipping drive mechanism includes a winding machine and a pull rope. The winding machine is mounted on the traveling mechanism, and the pull rope is wound around the winding machine and connected to the hanging frame or operating platform.

[0010] The hanging frame includes a vertical frame and a horizontal frame. One end of the horizontal frame is rotatably connected to the traveling mechanism, and the other end is fixedly connected to the top of the vertical frame. The operating platform is located at the bottom of the vertical frame, and the hanging interval is formed between the vertical frame and the traveling mechanism.

[0011] The operating platform is located on the side of the vertical frame facing away from the traveling mechanism.

[0012] The operating platform is equipped with a guardrail on its outer side, and the pull rope is connected to the guardrail.

[0013] The top of the vertical frame is provided with a first steering wheel that extends outward, and the pull rope is wound around the first steering wheel.

[0014] The walking mechanism is provided with a second steering wheel that extends upward, and the pull rope is wound around the second steering wheel.

[0015] A ladder is provided on the vertical frame.

[0016] The walking mechanism includes a walking frame and walking wheels located at the bottom of the walking frame. The hanging frame is rotatably connected to the top of the walking frame. The hanging interval is formed between the walking frame and the hanging frame. The walking frame is provided with a counterweight.

[0017] The walking frame is equipped with a support platform, and there are multiple counterweights, each of which is supported on the support platform.

[0018] Compared with the prior art, the advantages of this utility model are:

[0019] This utility model of a suspended platform for bridge maintenance and construction involves attaching the device to the side railing or wall of the bridge at intervals, positioning the operating platform outside the railing or wall. A traveling mechanism moves the entire device along the railing or wall to change the inspection position, allowing operators to inspect the outer side of the bridge from the platform. When encountering an obstacle, a flipping drive mechanism flips the bracket outwards, increasing the attachment interval to allow the obstacle to pass. The traveling mechanism then continues moving the entire device to overcome the obstacle. This suspended platform for bridge maintenance and construction allows for obstacle crossing simply by increasing the attachment interval, eliminating the need for complete disassembly and re-attaching. It facilitates obstacle crossing, saves time and labor, and improves work efficiency. Attached Figure Description

[0029] Figures 1 to 3This invention illustrates an embodiment of a suspended platform device for bridge maintenance and construction. The suspended platform device for bridge maintenance and construction in this embodiment includes an operating platform 1, a hanging frame 2, and a traveling mechanism 3. The top of the hanging frame 2 is rotatably connected to the traveling mechanism 3 and forms a hanging interval 4 between them. The operating platform 1 is located at the bottom of the hanging frame 2. The traveling mechanism 3 is provided with a flipping drive mechanism 5 for flipping the hanging frame 2 to change the size of the hanging interval 4.

[0030] When using this suspended platform device for bridge maintenance and construction, it is attached to the side railing or side wall of the bridge via a looping interval 4, positioning the operating platform 1 outside the side railing or side wall. The traveling mechanism 3 moves the entire device along the side railing or side wall to change the inspection position, allowing operators to stand on the operating platform 1 to inspect the outer side of the bridge. When encountering an obstacle, the flipping drive mechanism 5 flips the hanging bracket 2 outward, increasing the looping interval 4 to allow the obstacle to pass through. Then, the traveling mechanism 3 continues to move the entire device forward to overcome the obstacle. This suspended platform device for bridge maintenance and construction can overcome obstacles simply by increasing the looping interval 4, eliminating the need for complete disassembly and re-attaching, making obstacle crossing convenient, time-saving, labor-saving, and improving work efficiency.

[0031] Furthermore, in this embodiment, the flipping drive mechanism 5 includes a winding machine 51 and a pull rope 52. The winding machine 51 is mounted on the traveling mechanism 3, and the pull rope 52 is wound around the winding machine 51 and connected to the hanging frame 2 or the operating platform 1. The winding machine 51 can rotate the hanging frame 2 and the operating platform 1 by winding and unwinding the pull rope 52, thereby changing the size of the hanging interval 4, making operation convenient. The winding machine 51 can be an existing manual winch, electric winch, hoist, etc., and its specific structure is based on existing technology.

[0032] Furthermore, in this embodiment, as Figure 1 and Figure 3 As shown, the hanging bracket 2 includes a vertical frame 21 and a horizontal frame 22. One end of the horizontal frame 22 is rotatably connected to the traveling mechanism 3, and the other end is fixedly connected to the top of the vertical frame 21. The operating platform 1 is located at the bottom of the vertical frame 21, and the hanging interval 4 is formed between the vertical frame 21 and the traveling mechanism 3. Under the force of the flipping drive mechanism 5 (the tension of the pull rope 52), the hanging bracket 2 and the operating platform 1 can be kept in a suspended state outside the side rail or side wall. Of course, support wheels can also be added to the lower side of the horizontal frame 22 and / or the inner side of the vertical frame 21 to support them on the side rail or side wall, assisting the hanging bracket 2 and the operating platform 1 in a suspended state outside the side rail or side wall. A blocking block can also be set on the traveling mechanism 3 to prevent the horizontal frame 22 from flipping downwards, so that the hanging bracket 2 is in a suspended state outside the side rail or side wall under the blocking action of the blocking block. The specific method can refer to the existing technology or be optimized in the next generation of products.

[0033] In other embodiments, one end of the cross frame 22 can be fixedly connected to the traveling mechanism 3, and the other end can be rotatably connected to the top of the vertical frame 21. The rotatable connection can be achieved using existing hinges or pins.

[0034] Furthermore, in this embodiment, the operating platform 1 is located on the side of the vertical frame 21 facing away from the walking mechanism 3.

[0035] Furthermore, in this embodiment, a guardrail 11 is provided on the outer side of the operating platform 1, and the pull rope 52 is connected to the guardrail 11. Of course, in other embodiments, the pull rope 52 can also be connected to the operating platform 1, or to the vertical frame 21 or the horizontal frame 22. In practical applications, the pull rope 52 can be connected to at least one of the operating platform 1, the guardrail 11, the vertical frame 21, and the horizontal frame 22.

[0036] Furthermore, in this embodiment, the top of the vertical frame 21 is provided with an outwardly extending first steering wheel 6, and the pull rope 52 is wound around the first steering wheel 6. Specifically, the top of the vertical frame 21 is provided with an outward extension rod, and the first steering wheel 6 is located at the cantilever end of the outward extension rod.

[0037] Furthermore, in this embodiment, the walking mechanism 3 is provided with an upwardly extending second steering wheel 7, and the pull rope 52 is wound around the second steering wheel 7. Specifically, the walking mechanism 3 is provided with an upwardly extending upright, and the second steering wheel 7 is located at the top of the upright.

[0038] Furthermore, in this embodiment, a ladder 23 is provided on the vertical frame 21 to facilitate the operator's access.

[0039] Furthermore, in this embodiment, the walking mechanism 3 includes a walking frame 31 and walking wheels 32 located at the bottom of the walking frame 31. The hanging bracket 2 is rotatably connected to the top of the walking frame 31, and a mounting gap 4 is formed between the walking frame 31 and the hanging bracket 2. A counterweight block 8 is provided on the walking frame 31. The walking frame 31 can be supported on the bridge deck by the walking wheels 32. The walking frame 31 can be powered manually or driven by an engine, depending on the actual situation.

[0040] Furthermore, in this embodiment, the walking frame 31 is provided with a support platform 33, and multiple counterweights 8 are provided, each counterweight 8 resting on the support platform 33. Under the counterweight action of the counterweights 8, the operating platform 1 remains suspended under load. In actual use, the counterweights 8 can be added or removed as needed.
