[0001] The utility model belongs to the technical field of tunnel construction, and in particular relates to a tunnel construction bench structure. Background Art

[0002] Tunnels can be divided into traffic tunnels, hydraulic tunnels, municipal tunnels, and mining tunnels. When constructing tunnels, a gantry is needed to provide an operating platform for workers to build the tunnels. In order to facilitate use, the gantry can generally be moved.

[0003] The two sides of the existing gantry structure will extend in layers toward the inside of the tunnel, and the extended area will appear in different lengths due to the shape of the tunnel, so as to get close to the curved surface inside the tunnel and carry out subsequent processing. However, during processing, due to the distance between the layered structures on both sides of the gantry structure and the inner wall of the tunnel, during processing, impurities, construction materials, etc. on the side frame in the upper position will fall onto the lower side frame, thereby affecting the normal processing at the bottom position. Therefore, there are great limitations in actual use and there is room for improvement. Utility Model Content

[0004] The utility model aims to provide a tunnel construction platform structure to solve the problem that in the existing platform structure proposed in the above background technology, impurities on the upper side frame fall to the lower side frame during use, thus affecting normal processing.

During processing, the baffle in the side frame at the top position is pulled out, so as to protect the workers on the bottom side frame.

[0006] Preferably, the limiting member includes a toggle plate fixed on the top of one end of the baffle, a rubber block is bonded to the inside of the toggle plate, and the toggle plate is located outside the side frame. During protection, the baffle is pulled out of the through groove by the toggle plate and protection is performed.

[0007] Preferably, a screw hole is provided at one end of the baffle plate facing the side frame, and the limiting member also includes a limiting bolt screwed into the screw hole, which abuts against the interior of the side frame to prevent the baffle plate from being completely pulled out of the through groove. At the same time, this structure can also ensure the normal installation of the baffle plate in the early stage.

[0008] Preferably, the side frame is formed by welding a plurality of square tubes, and the limiting bolts and the rubber blocks are respectively abutted against the inner and outer surfaces of one of the square tubes of the side frame.

[0009] Preferably, a protective cloth is also provided on the bottom end surface of the side frame, and a magnet is bonded to the protective cloth (not shown in the figure). The protective cloth is adsorbed on the side frame by the magnet. During use, the protective cloth is used to protect the upper unknown side frame to prevent dust from falling and affecting the workers on the lower side frame.

[0010] Preferably, a placement plate is installed on the main frame and the side frame. During operation, the staff will stand on the placement plate. A side diagonal brace is welded between each side frame and the main frame, a main diagonal brace is welded on the inner side of the main frame, and walking wheels are also installed on the bottom end of the main frame.

[0011] Preferably, an external ladder is installed on the rear surface of the plurality of side frames, and the external ladder is welded and fixed to all the side frames.

At the same time, the protective component has a simple structure, is easy to process and manufacture, and has strong overall practicality. At the same time, in the pull-out protective component, buffer protection can also be performed to avoid the problem of pinching the fingers of workers due to excessive pulling speed.
