Problems solved by technology

[0002] In the prior art, when the working platform of the tunnel arch installation vehicle lifts heavy objects, there are no protective measures. It is difficult to know whether the lifted heavy objects exceed the rated lifting weight. During the equipment construction process, it is difficult for the operator to estimate the heavy objects to be lifted. Whether there is overloading or not is currently judged based on experience. There is an uncertain safety hazard. During construction operations, it may be safe at the beginning of hoisting. Exceeding the rated value, the boom may swing to a position, or lift to a position, because the center of gravity deviates from the safe position, causing the equipment to tip over and cause a safety accident

Abstract

The invention discloses a tunnel arch frame mounting vehicle. The tunnel arch frame mounting vehicle comprises a vehicle body, a horizontal swing mechanism mounted on the vehicle body, and a verticalswing arm mounted on the horizontal swing mechanism. The vertical swing arm comprises a mounting frame, a swing arm main body, a lifting oil cylinder set and a first pressure sensor, wherein the mounting frame is mounted on the horizontal swing mechanism, the swing arm main body is hinged to the mounting frame, the lifting oil cylinder set is connected with the swing arm main body and the mountingframe, the lifting oil cylinder set is hinged to the mounting frame, the lifting oil cylinder set is hinged to the swing arm main body, and the first pressure sensor is arranged on the lifting oil cylinder set. According to tunnel arch frame mounting vehicle, compared with the prior art, the safety of the arm rest hoisting operation can be remarkably improved, and safety guarantee is brought to constructors.

Description

technical field [0001] The present application relates to the technical field of tunnel construction, and more specifically, relates to a tunnel arch installation vehicle. Background technique [0002] In the prior art, when the working platform of the tunnel arch installation vehicle lifts heavy objects, there are no protective measures. It is difficult to know whether the lifted heavy objects exceed the rated lifting weight. During the equipment construction process, it is difficult for the operator to estimate the heavy objects to be lifted. Whether there is overloading or not is currently judged based on experience. There is an uncertain safety hazard. During construction operations, it may be safe at the beginning of hoisting. If the rated value is exceeded, the boom may swing to a position, or lift to a position, because the center of gravity deviates from a safe position, causing the equipment to tip over and causing a safety accident. [0003] Therefore, how to prov...
