Description

A kind of viaduct safety construction device

Technical Field

The utility model belongs to the technical field of construction equipment, and in particular relates to a safe construction device for an elevated bridge.

Background Art

The viaduct construction project includes the installation of sound barriers. As a vertical component perpendicular to the bridge deck, the sound barrier includes spaced columns and sound insulation panels fixed between adjacent columns. The columns are generally channel steel structures. When installing, the sound insulation panels need to be inserted into the channel structure of the columns from top to bottom and fixed to the columns by bolts or welding.

At present, the installation and construction of sound barriers rely on manual labor. Generally, workers use cranes or small cranes to lift the sound insulation panels to the upper end of the columns, and then use scaffolding and hydraulic lifting work platforms to lift the workers to the construction height. Then the workers assemble the sound insulation panels lifted by the crane with the columns and fix the panels to the columns through bolts or welding processes. The operation is cumbersome, the investment cost of equipment and labor is high, and the construction progress is difficult to be effectively improved. Moreover, this construction method has poor continuity and requires frequent transportation of panels to the construction area, which has low construction efficiency.

1-2, a device for safe construction of an elevated bridge includes a movable base, a lifting guide rail 2 is provided on the movable base, a lifting platform 3 is slidably connected to the lifting guide rail 2, a bottom plate 301 is provided at the bottom of the lifting platform 3, a through opening 302 is provided on the bottom plate 301, a cover plate 303 for closing the through opening 302 is hinged on the bottom plate 301, and a lifting mechanism is provided at the upper end of the lifting guide rail 2.

It can be understood by those skilled in the art that the viaduct construction project includes the installation of sound barriers. As a vertical component perpendicular to the bridge deck, the sound barrier includes columns arranged at intervals and sound insulation plates fixedly installed between adjacent columns. The columns are generally channel steel structures. When installing the sound insulation plates, they need to be inserted into the channel structure of the columns from top to bottom and fixed to the columns by bolts or welding. When the sound barrier is constructed through this application, the device is first moved to the sound insulation plate storage area through the movable base, and an appropriate amount of sound insulation plates are hoisted onto the lifting platform 3 through the hoisting mechanism. It should be noted that the amount of sound insulation plates stacked on the lifting platform 3 cannot affect the normal construction operation of the workers. After the sound insulation plates on the lifting platform 3 are hoisted, the construction personnel enter the lifting platform 3 and control the lifting platform 3 to rise to the construction height. At this time, a placement area with a storage space is formed on the movable base, and then more sound insulation plates are stacked in the placement area by manual transportation, thereby increasing the number of sound insulation plates that can be transported by the device, reducing the frequency of supplementary materials, and improving the efficiency of the installation and construction of the sound barrier. After the sound insulation panels are loaded, the device is moved to the construction area through the movable base. The workers on the lifting platform 3 operate the lifting mechanism to lift the sound insulation panels stacked on the lifting platform 3 first. When the sound insulation panels on the lifting platform 3 are installed, the workers on the lifting platform 3 flip the cover 303 upward to open the opening 302, and control the traction end of the lifting mechanism to lift the sound insulation panels placed on the movable base through the opening 302.

The cover plate 303 can be connected to the bottom plate 301 in a horizontal sliding direction. When the opening 302 needs to be closed, the cover plate 303 is slid toward the opening 302 to completely cover the opening 302. When the opening 302 needs to be opened, the cover plate 303 is slid away from the opening 302. In this embodiment, the position change of the cover plate 303 will not affect the space above and below the lifting platform 3, and while ensuring the stacking amount of the sound insulation board, it can also prevent the cover plate 303 from interfering with the construction personnel after opening the opening 302, affecting the normal construction operation of the construction personnel.

The movable base can be set up to move to the next construction site for construction and installation after the first construction site is installed, ensuring the continuity of construction, thereby speeding up construction efficiency and reducing the labor intensity of construction workers. The setting of the hoisting mechanism is convenient for effectively reducing the labor intensity of construction workers, speeding up construction efficiency and controlling labor costs.

As a preferred example of the above embodiment, referring to FIG. 1 and FIG. 2 , a placing platform 101 is provided on the movable base, and the placing platform 101 is located below the through opening 302. The placing platform 101 is provided to facilitate stacking of sound insulation panels on the movable base, and a limiting support block (not shown in the figure) adapted to the sound insulation panels can be provided on the placing platform 101 to increase the stability of the sound insulation panels stacked on the upper part thereof during the movement of the movable base.

As a preferred embodiment of the present application, referring to Figures 1 and 2, a crossbeam is connected to the upper ends of adjacent lifting rails 2, and a lifting mechanism 4 is provided between the crossbeam and the lifting platform 3. The provision of the crossbeam is conducive to improving the structural strength of the lifting rail 2, and is also conducive to providing an installation position for the lifting mechanism 4. Since the lifting mechanism 4 in the present application is a mature prior art, the present application does not limit the specific structure of the lifting mechanism 4, which can be driven by a hydraulic telescopic rod or by a sprocket or chain, and no further details are given here.

As a specific embodiment of the lifting mechanism, referring to Figures 1 and 2, the lifting mechanism includes a support frame 5, which is arranged at the upper end of the lifting guide rail 2.

A driving vehicle is provided on the horizontal guide rail 6, and a lifting assembly is provided at the bottom of the driving vehicle.

Workers use the lifting assembly to lift the sound insulation panels to the top of the trough structure, so that the panels are inserted into the trough structure from top to bottom. Furthermore, workers can adjust the position of the horizontal guide rail 6 through the setting of the rotating shaft 501. The setting of the horizontal guide rail 6 and the driving vehicle facilitates the flexible adjustment of the position of the lifting assembly, thereby replacing manual transportation of the panels, so that the panels can be transported from the stacking area to the installation area.

The structure and working principle of the lifting component are mature existing technologies and will not be elaborated on here. The present application does not make specific limitations on the lifting component. Preferably, the lifting component adopts a winch device 7, and the winch device 7 is connected to a control handle 701 through a wire. The winch device 7 has a cable for lifting materials, and a hook 702 is provided at the end of the cable. The worker controls the winch device 7 to release the cable to lower the hook 702 to the stacking area of the lifting platform 3 or the placement table 101. After fixing the plate and the hook 702, the winch device 7 is started to retract the cable to realize the vertical transportation of the plate. The rotation of the rotating shaft 501 and the movement of the drive vehicle can be controlled by setting the control handle 701, and the start and stop of the winch device 7 can also be controlled.

As a preferred example of the above embodiment, referring to Figures 1 and 2, a reinforcing rod 601 is fixedly connected between the horizontal guide rail 6 and the rotating shaft 501. The arrangement of the reinforcing rod 601 facilitates increasing the structural strength of the horizontal guide rail 6, improving its compression resistance, and increasing the safety of the device during use.

As a preferred embodiment of the lifting platform 3, referring to Figure 2, the lifting platform 3 is provided with guardrails around it, and an entrance is provided on the guardrails on either side of the lifting platform 3. A fence door 306 for blocking the entrance is rotatably connected to the guardrail, and a locking portion 307 is provided between the fence door 306 and the guardrail.

The provision of the guardrail facilitates effective safety protection for workers standing on the lifting platform 3 to prevent them from falling from the lifting platform 3. At the same time, the workers can also fix their safety belts on the guardrail to further increase the safety of the workers during the construction process. The provision of the guardrail is also beneficial for protecting the building materials stacked on the lifting platform 3 to prevent them from sliding off the lifting platform 3 and injuring the workers below, causing safety accidents.

As a preferred embodiment of the cover plate 303, referring to Fig. 1, a lifting handle 304 is provided on the cover plate 303. The provision of the lifting handle 304 facilitates workers to pull the cover plate 303 to rotate.

As a specific implementation of the movable base, referring to FIG. 1-FIG . 2 , the movable base includes a support base 1 , and a plurality of groups of wheels 102 are arranged around the bottom of the support base 1 .

Preferably, a limiting support plate 305 for supporting the cover plate 303 is welded to the bottom of the bottom plate 301. The setting of the limiting support plate 305 facilitates providing limiting support for one side of the cover plate 303 away from the hinged end.
