Description

Technical Field

[0001] The utility model relates to the technical field of construction operation platforms, in particular to a movable pneumatic lifting operation platform. Background Technique

[0002] Scaffolds are indispensable important temporary facilities in construction engineering. They are working platforms or transportation channels erected to ensure the safety and smooth progress of high-altitude operations. In construction, the scaffold project occupies a particularly important position. Working at heights is a job with a relatively high risk level. There are various types of scaffolds used for working at heights, including wooden scaffolds, bamboo scaffolds, steel pipe scaffolds, fastener-type scaffolds, bowl-coupling scaffolds, portal scaffolds, etc.

[0003] When the existing scaffolds are in use, the erection specifications are relatively high, and the erection, demolition, and use spaces are restricted, resulting in a more cumbersome erection process. It requires the cooperation of multiple workers to assemble. During work, due to the replacement of the working surface, the scaffolds often need to be repeatedly disassembled and assembled, resulting in a relatively large labor intensity.

[0004] Therefore, in view of the fact that the above-mentioned existing scaffolds are not convenient to erect and need to be repeatedly disassembled, adjusted, and installed according to the working position, a movable pneumatic lifting operation platform can be designed. By setting universal wheels, it is convenient to move the whole device. At the same time, through the operation of the telescopic cylinder, its output end can push the fixed seat upward, and the fixed seat pushes the operation platform upward, thereby realizing the height adjustment of the operation platform. Content of the Utility Model

[0005] In order to overcome the problems that the existing scaffolds have relatively high erection specifications, restricted erection, demolition, and use spaces, resulting in a more cumbersome erection process, and often need to be repeatedly disassembled and assembled due to the replacement of the working surface during work, with a relatively large labor intensity.

[0006] The technical solution of the utility model is: a movable pneumatic lifting operation platform, which includes a fixed frame; it also includes universal wheels, cross beams, telescopic cylinders, and fixed seats. Pillars are installed at the corners of the upper surface of the fixed frame. The top surfaces of the four pillars are provided with an operation platform. A guardrail is arranged at the outer edge position of the upper surface of the operation platform. Universal wheels are installed at the corners of the bottom surface of the fixed frame. Cross beams are installed at the upper positions of the opposite surfaces of the left and right pillars. Symmetrically arranged telescopic cylinders are installed on the left and right sides of the upper surface of the fixed frame. The telescopic ends of the telescopic cylinders pass through the corresponding cross beams and are installed with fixed seats. The top surface of the fixed seat is connected to the bottom surface of the operation platform.

[0007] Preferably, by setting universal wheels, it is convenient to move the whole device. At the same time, through the operation of the telescopic cylinder, its output end can push the fixed seat upward, and the fixed seat pushes the workbench upward, so as to realize the height adjustment of the workbench. Compared with the traditional scaffolding erection, disassembly and movement that require four people, this device only needs two people to complete the operation, saving time, thus solving the problems that the scaffolding erection specifications for existing high-altitude operations are relatively high, and the erection, demolition and use space are restricted.

[0008] Preferably, a limiting rod is slidably connected inside each of the four columns, and the top surface of the limiting rod is connected to the bottom surface of the workbench. By setting the limiting rod, when the workbench is lifted or lowered, the limiting rod will slide inside the column, thus assisting the lifting and lowering of the workbench and improving the stability of the lifting and lowering.

[0009] Preferably, four positioning holes are equally spaced on the left and right side surfaces of the four columns and the four limiting rods. A positioning bolt is threadedly connected inside the lowermost positioning hole, and a positioning nut is sleeved on the threaded surface of the positioning bolt. By setting the positioning holes, after the workbench is moved to the working height, the positioning bolt can be inserted into the corresponding positioning hole, and then the positioning bolt is fixed by the positioning nut, thereby fixing the position of the limiting rod and improving the safety of the equipment during use.

[0010] Preferably, a reinforcing rod is welded between the opposite surfaces of the front and rear corresponding columns, and fixing rods are welded to the front and rear sides of the inner surface of the fixed frame. By setting the reinforcing rod and the fixing rod, the overall strength of the device can be improved, and shaking during use can be avoided.

[0011] Preferably, one end of a ladder is welded to the left side surface of the fixed frame, and the other end of the ladder is welded to the left side surface of the left cross beam. By setting the ladder, it is convenient for the staff to climb to the surface of the workbench, which is convenient to use and has high safety.

[0012] Preferably, mounting seats are installed at the left and right ends of the front and rear side surfaces of the fixed frame. A leg is inserted into the mounting seat, and a fixing screw is threadedly connected through the upper surface of the mounting seat. The leg is connected to the mounting seat through the fixing screw. A collar is installed at the end of the leg away from the mounting seat, and a screw rod is threadedly connected to the inner surface of the collar. The bottom surface of the screw rod is rotatably connected to a gasket. By setting the mounting seat, after the leg is inserted into the mounting seat, the fixing screw is screwed in from the top of the mounting seat to fix the leg, and then the screw rod is rotated. Under the cooperation of the internal thread of the collar, the screw rod will rise and fall, thereby adjusting the position of the gasket. With the cooperation of the four groups of gaskets, the whole device can be leveled, and the stability during use can be improved.

[0013] Preferably, a handle is inserted through the outer surface of the top rotating shaft of the screw rod, and protective sleeves are sleeved on both ends of the handle away from the screw rod. By providing the handle, it is convenient for the operator to rotate the screw rod, and by providing the protective sleeves, it is convenient to grip the handle and improve the anti-slip effect.
