Description
Technical Field
[0001] The utility model relates to the technical field of tunnel construction equipment, in particular to a trestle with a hoisting function. Background Art
[0002] In the current tunnel construction process, it is often necessary to bury the culvert at the bottom of the tunnel. Traditional culvert lifting operations usually rely on cranes or excavators, which not only have high equipment costs and complex operations, but also interfere with other construction operations in the tunnel because the lifting equipment occupies the tunnel space. To solve this problem, a technical solution has emerged to integrate the lifting device into the trestle body. For example, the Chinese patent document with the announcement number: CN206129292U discloses a new type of trestle trolley, which includes a trolley body, a bridge approach, a gantry structure and a lifting device. The bridge approach is respectively hinged at both ends of the trolley body, the gantry structure is installed on both sides of the center position of the trolley body, the gantry includes a grid and a lifting beam, the grid is respectively installed at relative positions on both sides of the center of the trolley body, the lifting beam is installed on the top of the grid, the lifting device is installed on the lifting beam, and the lifting device includes an electric hoist, a sling and a hook, the electric hoist is installed on the lifting beam, the sling is connected to the electric hoist, and the hook is connected to the end of the sling. When the culvert transport vehicle is located under the lifting beam, the lifting device can perform longitudinal lifting operations without the need for additional mechanical equipment. However, since the lifting device cannot move laterally, the lateral adjustment of the culvert still needs to be done manually or with other mechanical equipment. This is not only time-consuming but also poses a safety risk when manual adjustment is required. When the culvert installation location is far away from the lifting device laterally, other mechanical equipment is still needed to move the culvert to the specified location, and these mechanical equipment still occupy tunnel space.

[0041] Embodiment 1
[0042] Figures 1 to 7An embodiment of a trestle with a lifting function of the utility model is shown. The trestle with a lifting function of this embodiment comprises a trestle body 1, a lifting device 3 and columns 2 arranged on both sides of the trestle body 1. The columns 2 are provided with longitudinal tracks 4 extending to the front end of the trestle body 1. The lifting device 3 comprises a transverse track 31, a lifting mechanism 32, a first running mechanism 33 arranged on the longitudinal track 4, and a second running mechanism 34 arranged on the transverse track 31. The first running mechanism 33 is connected to the transverse track 31, and the second running mechanism 34 is connected to the lifting mechanism 32. Specifically, the column 2 is arranged at the front end of the trestle body 1; the I-beam serves as the transverse track 31, and the second running mechanism 34 runs on the lower flange of the I-beam. Of course, in other embodiments, the column 2 is also arranged at other positions of the trestle body 1; the transverse track 31 can also be other structures, and the second running mechanism 34 can also be in other matching modes with the transverse track 31. It should be noted that the longitudinal direction mentioned in the specification refers to the length direction of the trestle body 1, the transverse direction refers to the width direction of the trestle body 1, and the front end is the excavation end of the tunnel.
[0043] In the trestle with a lifting function of this embodiment, the lifting device 3 cooperates with the longitudinal track 4 through the first running mechanism 33 to realize the movement of the lifting mechanism 32 in the longitudinal direction. The lifting mechanism 32 realizes lateral movement on the lateral track 31 through the second running mechanism 34. The lifting range of the lifting mechanism 32 is wide. When the vehicle transporting the culvert travels to the column 2 on the trestle body 1, the lifting mechanism 32 can move to the top of the vehicle and lift the culvert. After lifting the culvert, the lifting mechanism 32 can move to the top of the culvert where it needs to be installed, and accurately drop the culvert to the designated position. No other mechanical equipment is required to adjust the lateral position of the culvert. The manual adjustment of the culvert has low participation, and the use process is safe and convenient, saving time and effort, and has high construction efficiency. It occupies a small space in the tunnel and causes less interference to other construction operations in the tunnel.
[0044] Furthermore, in this embodiment, the hoisting mechanism 32 includes a lifting drive 321, a sling 323, and a hook 322 connected in sequence. Preferably, the lifting drive 321 is an electric hoist, which is connected to the hook 322 through the sling 323. The electric hoist has precise control and strong carrying capacity.
[0045] The method of using the trestle with hoisting function of the present embodiment is as follows:
[0046] The culvert transport vehicle drives onto the trestle body 1 and stops after driving to the column 2. The hoisting mechanism 32 first moves to the bottom of the culvert transport vehicle under the driving action of the first running mechanism 33 and the second running mechanism 34. Then, the electric hoist lowers the sling 323, and the worker locks the hook 322 to the culvert. Then the electric hoist lifts the sling 323 and lifts the culvert. After that, the hoisting mechanism 32 is again driven by the first running mechanism 33 and the second running mechanism 34 to the top of the culvert installation position. After the hoisting mechanism 32 is in place, the electric hoist lowers the sling 323 and lowers the culvert to the corresponding position. Then the worker releases the hook 322, and the electric hoist lifts the sling 323 back, and finally the culvert is buried. Repeat the above steps until all culverts are buried.

Compared with the third embodiment, the bearing capacity of the longitudinal track 4 is larger; the longitudinal track 4 can be moved in the longitudinal direction under the drive of the track shifting mechanism 6, and the length of the longitudinal track 4 extending out of the trestle body 1 can be adjusted according to actual construction needs. When the longitudinal distance between the culvert installation position and the transport vehicle is close or space is needed for construction in front of the tunnel, the longitudinal track 4 can be moved to the rear end of the trestle body 1 to make room for other construction operations at the front end of the tunnel. Compared with the third embodiment, the trestle with lifting function of the present embodiment causes less interference to the construction operations at the front end of the tunnel.
[0056] Furthermore, in this embodiment, two adjacent columns 2 on the same side of the trestle body 1 are connected by a longitudinal beam 5.
