Description

Technical Field

[0001] The utility model belongs to a tunnel main body trolley construction work platform and a safety protection device, in particular to a tunnel trolley construction work platform and a safety protection device. Background Art

[0002] During the main construction of the tunnel, all types of construction trolleys need to be equipped with construction platforms, ladders, safety guardrails, etc. to play a safety protection role and prevent materials, equipment and personnel from falling and causing casualties. The existing trolley ladders and guardrails are of various forms and use a wide variety of materials. Many trolleys even process ladders and guardrails by themselves, with different standards and uneven quality, which significantly reduces the safety protection role and breeds safety hazards.

[0003] The patent application with publication number CN 212837818U discloses a liftable work platform for a tunnel main body construction trolley, comprising: a work platform, a safety mechanism, and a power mechanism. When the power mechanism is disconnected from the connecting cable, the work platform begins to fall, and the piston block moves downward under the action of the first elastic member. When the piston block moves to the point where the limit rod and the piston block are no longer in contact, the limit rod is disengaged from the through hole B under the action of the third elastic member, and then the moving block moves upward under the action of the second elastic member. During the movement of the moving block, the distance between the moving block and the wing plate of the I-beam column gradually decreases until it is zero. The moving block gradually clamps the wing plate of the I-beam column under the action of friction, and the falling speed of the working platform gradually slows down until it stops, thereby increasing the safety of the device.

[0004] The above-mentioned novel utility model simply combines the working platform with the moving block and the I-beam column, which is prone to safety problems.

[0005] In summary, the utility model therefore provides a tunnel trolley construction work platform and a safety protection device to solve the above problems. Utility Model Content
