Description

Technical Field

[0001] This utility model relates to the field of drainage device technology, specifically a water drainage device for tunnel excavation construction. Background Technology

[0002] Tunnels are engineering structures buried underground, representing a form of human utilization of underground space. Tunnels can be categorized into traffic tunnels, hydraulic tunnels, municipal tunnels, mining tunnels, and military tunnels.

[0003] During tunnel excavation, especially in downhill tunnels, if water-bearing rock strata are encountered, water will rapidly gush out from the rock fissures, causing water accumulation inside the tunnel and affecting the construction progress. It is necessary to drain the water from the tunnel. Currently, the common method is to use diesel pumps to pump the water out. However, there are some functional shortcomings in actual use, and there is room for improvement. For example, tunnel construction sites are generally in mountainous areas with many slopes and rugged roads. Diesel pumps are large and heavy, making them difficult to carry manually and lacking the ability to be easily transported and moved.

[0004] Now, a new type of water drainage device for tunnel excavation is proposed to solve the above problems. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution: a water drainage device for tunnel excavation construction, comprising a steel frame, two sets of handles fixedly connected to the left side of the steel frame, a controller fixedly connected to the top of the handles, a storage box fixedly connected to the left side of the top of the steel frame, an inlet coil and an outlet coil horizontally placed inside the storage box, a diesel pump fixedly connected to the right side of the top of the steel frame, and an assistive component for facilitating walking on tunnel slopes at the bottom of the steel frame.

[0007] The power assist assembly includes two sets of wheel mounting brackets, which are respectively fixedly connected to the front and rear ends of the bottom of the steel frame. A bearing seat is fixedly connected to the outer side of the wheel mounting bracket, and a drive shaft is longitudinally installed inside the bearing seat. A drive wheel is fixedly connected to the end of the drive shaft. A speed reducer is fixedly connected to the inner side of the wheel mounting bracket, and a drive motor is fixedly connected to the input end of the speed reducer. A lithium battery pack is fixedly connected to the bottom of the steel frame.

[0008] As a further technical solution of this utility model, the wheel fixing bracket is symmetrically distributed about the vertical center line of the steel frame, and the drive shaft passes through the bearing seat and is connected to the output end of the reducer.

[0009] As a further technical solution of this utility model, there is a distance between the steel frame and the drive wheel, and the drive motor, lithium battery pack and controller are electrically connected.

[0010] As a further technical solution of this utility model, electric cylinders are respectively installed at the front and rear ends of the top left side of the steel frame, and fixed tubes are respectively welded at the front and rear ends of the bottom left side of the steel frame. A push rod is inserted into the bottom end of the fixed tube from bottom to top. A pressure plate is fixedly connected to the bottom end of the push rod. An inclined steel block is fixedly connected to the bottom end of the pressure plate. Multiple sets of sharp claws are welded to the bottom end of the inclined steel block.

[0011] As a further technical solution of this utility model, the top end of the push rod is connected to the output end of the electric cylinder, and the push rod can slide up and down along the inside of the fixed cylinder.

[0012] As a further technical solution of this utility model, the pressure plate and the inclined steel block are assembled by bolts, and the claws are arranged at equal intervals.

[0013] As a further technical solution of this utility model, two sets of support blocks are fixedly connected to the left and right sides inside the storage box, and a support plate is horizontally placed on the top of the support block. The front and rear ends of the support plate are respectively provided with reserved grooves.

[0014] As a further technical solution of this utility model, the shape and size of the outside of the support plate are adapted to the shape and size of the inside of the storage box, and the support plate can move up and down along the inside of the storage box.

[0015] Compared with the prior art, the beneficial effects of this utility model are: the water drainage device for tunnel excavation construction not only realizes the function of easy transportation and movement, but also realizes the function of stable stopping on slopes, and also realizes the function of easy layered storage of coils.

[0016] (1) The vehicle is equipped with a steel frame, wheel fixing frame, bearing seat, drive shaft, drive wheel, reducer, drive motor, lithium battery pack, handle and controller.

When it is necessary to stop in the descending tunnel, the electric cylinder 10 is started. The electric cylinder 10 extends downward and pushes the push rod 11 down along the fixed cylinder 9. The pressure plate 12 at the bottom of the push rod 11 touches the ground, and the sharp claws 14 on the inclined steel block 13 pierce the ground to increase the grip and make the equipment stop stably. Place the inlet coil 21 and outlet coil 22 into the storage box 17. The storage box 17 is divided into layers by the support plate 19.
