Description

Technical Field

[0001] The utility model relates to tunnel cable trough lining construction equipment, belonging to the field of tunnel construction equipment. Background Art

[0002] Tunnel cable trough lining construction refers to the lining construction of the cable trough inside the tunnel to protect the cables and provide good support and protection. First, concrete is poured at the bottom of the cable trough to form a solid foundation. Then, according to the design requirements, concrete is poured to the side walls layer by layer to form a lining. Before pouring concrete, suitable formwork needs to be installed to ensure the accurate size and flatness of the lining.

[0003] In the prior art, after the templates are laid inside the cable trough, there are connection points between the templates. Due to the longitudinal irregularity of the tunnel, settlement will occur. The traditional tunnel cable trough lining construction is constructed 12 meters at a time. Due to the longitudinal irregular settlement of the tunnel, it is easy to cause the trough concrete to crack and cause continuous collapse. Installing reinforcements at the template connection will hinder the continuity of the trench body reinforcement steel bars, so that the trough cracking phenomenon still cannot be improved.

[0004] In summary, the utility model therefore provides a tunnel cable trough lining construction equipment to solve the above problems. Utility Model Content

[0008] Furthermore, the lifting hook includes a load-bearing seat, which is fixedly connected to the bottom of the electric hoist, and a mounting frame is fixedly connected to the bottom of the load-bearing seat, and three groups of lifting ropes are evenly installed from left to right at the bottom of the load-bearing seat and inside the mounting frame, and bending limit wire drums are penetrated between the two sides of the bottom of the mounting frame and the two sides of the bottom, and a vertical wire drum is penetrated between the middle part of the bottom of the mounting frame and the middle part of the bottom of the inner wall, one end of one group of lifting ropes penetrates the top of the vertical wire drum and extends to the bottom of the vertical wire drum, and one end of the other two groups of lifting ropes respectively penetrates the top of the two bending limit wire drums and extends to the bottom of the two bending limit wire drums.

[0009] Furthermore, a hanging plate is fixedly connected between one ends of the three groups of hanging ropes, and a hanging hook is fixedly connected to the bottom of the hanging plate.

[0010] Furthermore, the two bending and limiting wire drums are mirror-symmetrical, and the two bending and limiting wire drums are both fixedly connected to the mounting frame.

[0015] The three sets of lifting ropes inside the lifting hook are released at the same time to drive the lifting platform to move downward, and the cable trough template is hooked up by the lifting hook. The three sets of lifting ropes are reeled in at the same time to lift the cable trough template. The two bending limit wire drums are mirror-symmetrical.
