Description

Technical Field

[0001] The utility model relates to the technical field of tunnel construction, in particular to a multi-purpose protective hoisting device for a tunnel. Background Art

[0002] As my country begins to pay attention to the construction and development of underground projects, more and more tunnel construction is involved, especially underground pipelines in cities. Underground pipelines in cities are affected by the construction space in the city, resulting in smaller excavation slopes for foundation pits, and long tunnels need to be excavated continuously, which is greatly affected by geology. For foundation pits in cities where the space is limited and slopes cannot be cut, and the depth is shallow and the length is long, there is generally no protection or steel sheet pile protection. Lack of protection may cause foundation pit collapse and slope soil to slide to the construction site in the pit, affecting personnel safety. At the same time, it is affected by weather conditions and the construction quality of welding construction is low. The use of steel sheet pile protection will greatly increase the cost and construction costs. At the same time, the turnover of steel sheet piles is slow, affecting the construction progress.

[0005] With the above structural design, a top plate is set on the top of the support frame, which can effectively block falling objects from above the support frame and has the functions of rain protection and sun protection; protective plates are set on both sides of the support frame to prevent foundation pit collapse and slope soil from falling on both sides, ensuring the construction safety of workers and improving the construction quality of pipeline welding.

[0006] Preferably, a limiting frame is equidistantly fixedly connected to the support column, the limiting frame is L-shaped steel, the lower end of the support column is fixedly connected to a bearing plate, and the protective plate is inserted from a gap formed between the limiting frame and the support column and overlapped on the bearing plate.

[0007] With the above structural design, the protective plate is connected to the support frame in an inserting manner, and the device is easy to assemble and disassemble, which is convenient for multiple uses in the future.

[0008] Preferably, a cross is arranged between the rectangular frames, a slide groove is provided at the lower end of the cross, a slider is slidably connected in the slide groove, a rotating shaft is rotatably connected at the lower end of the slider, and a hanging ring is fixedly connected at the lower end of the rotating shaft.

[0009] With the above structural design, the slider can slide forward, backward, left and right in the slide groove set inside the cross. A lifting motor is set at the bottom of the lifting ring to assist workers in lifting heavy objects during construction. It can also be used for the connection and stabilization of small pipes. The lifting motor moves forward, backward, left and right according to construction requirements to facilitate construction.

[0010] Preferably, a reinforcing steel pipe is fixedly connected between two adjacent support columns.

[0011] By adopting the above structural design, reinforcing steel pipes are arranged between the supporting columns, which increases the integrity and firmness of the device, can better prevent the soil from falling from the slope, and protect the safety of the construction workers.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] A top plate is set on the top of the support frame, which can effectively block the falling objects above the support frame and has the function of rainproof and sunshade; protective plates are set on both sides of the support frame to prevent the foundation pit on both sides from collapsing and the soil on the slope from falling, ensuring the safety of workers and improving the construction quality of pipeline welding. This device greatly improves the safety and economy of long tunnel construction, and also enhances the comfort, work efficiency and construction quality of workers. BRIEF DESCRIPTION OF THE DRAWINGS
