Description

Technical Field

[0001] The utility model relates to the technical field of transport trolleys, in particular to an anti-falling transport trolley for inclined shaft expansion. Background Art

[0002] In geological work, it is necessary to use drilling equipment to drill a small diameter and deep cylindrical hole into the ground, also known as a borehole. The pre-selected surface is drilled to form a well, so that a cylindrical hole with a certain depth is drilled underground. In the excavation process, a large amount of rock and debris needs to be transported to the outside. During the drilling transportation, a trolley is used for transportation. During the use of the trolley, a gap is reserved between the side wall of the trolley and the inner wall of the borehole. It is easy to cause safety accidents such as stepping on air during the handling and transportation process. Therefore, it is necessary to use a fall-proof transport trolley for inclined shaft expansion.

[0003] After searching, the Chinese patent with announcement number CN211116113U discloses an inclined shaft manned trolley that runs on tracks. The advantage of this structure is that a bottom platform is fixed at the bottom of the manned platform, and the inclination angle of the bottom platform is the same as the inclination angle of the inclined shaft. Rollers are installed at the bottom of the bottom platform, and guardrails are fixed around the manned platform. The bottom platform is towed by a single-rope winding mine double-drum winch inside the mine, which can make the bottom platform run safely and smoothly on the track, allowing construction workers to enter and exit the inclined shaft more conveniently without relying on ladders, thereby improving construction efficiency and greatly improving the safety of manned transportation.

[0004] However, in actual use, since the loading platform and the bottom platform are fixedly connected, the internal angle of the drilling changes according to the change of the digging angle, and the bottom platform moves, it is easy to cause a large angle to be formed between the loading platform and the ground, which not only affects the safety of the construction personnel on the loading platform, but also when the loading platform needs to be used to transport materials, it is easy for materials to fall and cause safety accidents.

[0005] The existing trolley structure is a fixed structure as a whole, and the angle of the table cannot be adjusted. Since the internal angle of the drilling trolley changes according to the digging angle, the angle of the trolley table becomes tilted, which is not conducive to the workers' work. In addition, it is difficult to perform multi-angle assistance in the existing trolley angle adjustment structure, and it is easy to tilt and fall during use. Utility Model Content

[0015] 2. By setting up a protective component, a protective fence structure is formed by the telescopic column and the protective handle, and then the limit plate and the auxiliary plate are used to form a protective structure for the side of the flap, thereby reducing the possibility of workers falling.
