Description

Technical Field

[0001] The utility model relates to the technical field of bridge construction, in particular to a suspension device for bridge bottom surface construction. Background Art

[0002] After the main construction of the bridge road is completed or when the bridge is repaired and maintained at a later stage, a large number of bridge bottom surface construction operations are involved, such as the installation of pipelines, the installation and maintenance of street lights, or the painting of the bottom surface of the steel box girder, etc. This type of construction generally uses a hanging basket or platform hung on the bridge curb as a carrier for the staff. Compared with the method of relying on a ground elevator to lift the staff to the work surface, it has the advantages of small footprint and no impact on ground traffic. However, the hanging basket or platform in the prior art generally operates on one side. If both sides of the bridge need to work, multiple devices need to be equipped, and the working area is also small, making it difficult to include the center of the bridge bottom in the working range. Therefore, it is necessary to provide a new suspension equipment for bridge bottom surface construction to solve the above technical problems. Utility Model Content

[0003] In order to solve the above technical problems, the utility model provides a suspension device for bridge bottom surface construction which has an adjustable working area and provides stable support.

[0004] The utility model provides a suspension device for bridge bottom surface construction, comprising a driving vehicle arranged near two curbstone sides of the bridge and a suspension assembly connected to the two driving vehicles, the suspension assembly comprising a suspension frame connected to a preset hydraulic cylinder output end on the driving vehicle, a support frame is arranged on the side wall of the suspension frame facing the outside of the bridge, a mounting plate is horizontally arranged on the support frame, the mounting plate is vertically slidably matched with the lifting frame through a preset through hole, a steel hook is arranged at the bottom of the lifting frame, a winding rod is rotatably arranged on a side of the support frame away from the suspension frame, and winding steel wires are wound around both ends of the winding rod;

[0005] The equipment also includes a treading platform composed of a plurality of treading frames, and the top of the treading platform is connected with the winding steel wire and the steel hook respectively through a hanging ring and a hook.

[0006] It should be noted that by suspending the treading platform between the suspension components of the two driving vehicles, a working platform suspended through the bottom of the bridge can be provided, which is convenient for workers to stand on the treading platform to perform full-range construction work on the bottom of the bridge. At the same time, in order to provide rigid support and secondary protection for the treading platform, the utility model uses a rigid structure lifting frame with a steel hook to connect the treading platform to prevent the treading platform from shaking. In addition, the winding motor is a self-locking motor, which can avoid the phenomenon of accidental wire protection when winding the steel wire.

[0007] Preferably, a plurality of connection frames are provided at the bottom of the tread frame, and the connection frames corresponding to the bottoms of adjacent tread frames are plugged with insertion rods, and both ends of the insertion rods are screwed with nuts through preset threads.

[0008] The treading platform adopts a splicing method of multiple treading frames, and the staff can flexibly combine them according to the width of the construction bridge, thereby improving the application scenarios of the utility model.

[0009] Preferably, a rack is provided on the side wall of the lifting frame facing the inner side of the bridge;

[0010] A driving rod is rotatably provided on the mounting plate, and the driving rod is connected to the output end of a driving motor arranged on the mounting plate. The driving rod is provided with a driving gear for engaging with the transmission rack at a corresponding rack.

[0011] By meshing the drive gear and the rack, the drive motor can drive the drive rod to rotate to achieve vertical sliding of the lifting frame relative to the mounting plate, thereby fine-tuning the distance between the stepping platform and the bottom of the bridge. At the same time, the drive motor is a self-locking motor to further prevent the platform from falling.

[0012] Preferably, one end of the winding rod is connected to an output end of a winding motor disposed on the support frame.

[0013] Preferably, a plurality of guide rods are provided through the suspension frame, and the bottom ends of the guide rods are fixedly connected to the top surface of the driving vehicle.

[0014] Preferably, the suspension frame is provided with two sets of rotatably connected vertical guide rollers at the side walls close to the bridge curb, and is provided with rotatably connected transverse guide rollers at the top surface close to the bridge curb.

[0015] By setting the vertical guide rollers and the transverse guide rollers, after the suspension frame is hung on the curbstones on both sides of the bridge, the operation safety and stability of the whole equipment are improved through the close contact between the rollers and the curbstones. At the same time, when the driving trolley moves, the friction between the vertical guide rollers and the transverse guide rollers and the curbstones is rolling friction, which reduces the movement resistance of the whole machine.

[0016] Compared with the related art, the suspension equipment for bridge bottom surface construction provided by the utility model has the following beneficial effects:

[0017] The utility model greatly increases the working area and working stability of the workers by setting a stepping platform that can penetrate and be suspended on the bottom surface of the bridge. Moreover, the stepping platform can be spliced ​​according to the construction requirements and the working area can be adaptively changed, which is convenient to use.
