Description
Technical field
The utility model is related to a kind of construction equipments, are a kind of devices adjusted for tunnel arch jacking, belong to construction
Technical field.
Background technology
In engineering construction, during especially constructing tunnel is built, need to carry out the in place of the auxiliary materials such as arch or equipment
Installation.Currently, often using the interim artificial method installed in place, but it is accurate using cannot be satisfied when manually carrying out arch installation
Jacking requires, and needs that mounting and adjusting is repeated, takes a lot of work and time-consuming, influences the construction efficiency of single process.How to accomplish quickly
Jacking to design position, while again can low cost be improved, meet construction quality, just at the scene construction in need
It to solve the problems, such as in time.
Invention content
Deficiency discloses a kind of tunnel arch jacking regulating device to the utility model according to prior art.The utility model
Solve the problems, such as to be to provide it is a kind of make it is simple, easy to use, for construction sites such as concrete tunnels to equipment or material
Carry out the auxiliary device of lifting operation.
The utility model is achieved through the following technical solutions：
Tunnel arch jacks regulating device, including pedestal, supporting rod, handle, lifting pin and bracket, it is characterised in that：Bottom
Seat is welded to connect with supporting rod made of steel pipe, and lifting pin can move freely in supporting rod, and handle, which includes center, to be had and top
The matched nut of rising stem screw thread and the handle for being welded in nut both sides；Replaceable connecting bracket is set at the top of spiral lifting pin.
The utility model bracket is U-shaped structure, and with lifted equipment or material cross-section structure matching, bracket bottom surface with
Spiral lifting pin top is connected by the bolt being mutually matched.
Under longer-term use state, the utility model bracket bottom surface is with spiral lifting pin top by being welded to connect fixation
It is decoupled with cutting.
The steel plate that the pedestal is equipped with non-slip mat by bottom surface quadrangle is made.
Handle nut bottom surface be provided with can sliding opposite with supporting rod top surface slip ring.
It is adjusted the utility model has the beneficial effects that the utility model is practically applicable to tunnel arch jacking, it can be right as needed
Different to be lifted equipment or material carries out stable jacking, apparatus structure utilitarian design, fixed effect is fine, cross-sectional structure
Matched structure design has preferable positioning function, and the site operation to needing to carry out relatively accurate jacking positioning has preferable
Operating characteristics, present apparatus scene can directly make, cheap, securely and reliably, highly practical, improve construction efficiency, save
Manpower installation cost, is convenient for carrying.
Description of the drawings
Fig. 1 is utility model device schematic diagram.
In figure, 1 is pedestal, and 2 be supporting rod, and 3 be handle, and 4 be lifting pin, and 5 be bracket.
Specific implementation mode
Specific implementation mode, which is to the utility model, to be further illustrated to the utility model With reference to embodiment
The further explanation of principle, does not limit the utility model in any way, does not have with the same or like technology of the utility model
Range beyond the utility model protection.
In conjunction with Fig. 1.
Tunnel arch jacks regulating device, including pedestal 1, supporting rod 2, handle 3, lifting pin 4 and bracket 5, pedestal 1 and steel
Supporting rod 2 made of pipe is welded to connect, and lifting pin 4 can move freely in supporting rod 2, and handle 3 has including center to be pushed up with rotation
The matched nut of 4 screw thread of rising stem and the handle for being welded in nut both sides；Replaceable connecting bracket 5 is arranged in 4 top of lifting pin.
Use bracket 5 for U-shaped structure, and with lifted equipment or material cross-section structure matching, 5 bottom surface of bracket and spiral
4 top of lifting pin is connected by the bolt being mutually matched.In this example, when lifting of rectangle crossbeam reinforcing bar is being carried out, is being used
The U-shaped structure bracket 5 of opening.
It fixes and is lifted in application, 5 bottom surface of bracket and 4 top of spiral lifting pin are by being welded to connect fixation in the long period,
It can be decoupled by cutting after the completion of use.
The steel plate that pedestal 1 is equipped with non-slip mat by bottom surface quadrangle is made.
3 nut bottom surface of handle be provided with can sliding opposite with 2 top surface of supporting rod slip ring.
As shown in Figure 1, when needing to carry out the accurate jack-up construction of tunnel reinforcement centering, by 1 placement operation platform of pedestal,
Arch is put into inside bracket 5, rotates clockwise handle 3, and arch carries out displacement straight up until design position, you can is encircleed
Frame fixes construction, after completing fixed work, rotating handle 3 can remove portable tunnel arch jacking regulating device counterclockwise,
Accurate jacking work can be completed, meet its construction.
It is easy to operate using the present utility model, improve constructing tunnel efficiency, it is ensured that construction construction precision.
