[0001] This utility model relates to the field of tunneling machines, specifically a cutting reducer and a tunneling machine that prevent water seepage. Background Technology
[0002] Currently, with the rapid growth of urban rail transit, railways, highways, water conservancy, municipal engineering and other construction projects in China, my country's tunneling machinery has also ushered in rapid development. Tunneling machines are machines used to excavate tunnels under flat ground. They are highly precise engineering machines, specially designed to build the world's most advanced and longest tunnels.
[0003] However, current tunneling machines still have some shortcomings. The existing tunneling machines have not fully considered the protective structure. If the protective structure of the tunneling machine is not fully considered during use, liquid may seep in, which may affect the performance of the cutting reducer and cannot guarantee the heat dissipation efficiency of the cutting reducer. In subsequent operation, the machine may be interrupted due to high temperature, which is inconvenient for the staff to use the cutting reducer.
[0004] Therefore, there is an urgent need to improve this shortcoming. This utility model is to study and improve the existing structure and its deficiencies, and provides a cutting reducer and tunneling machine that prevents water from seeping in. Utility Model Content
[0005] The purpose of this invention is to provide a cutting speed reducer and tunneling machine that prevent water infiltration, so as to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a cutting reducer for preventing water infiltration, comprising a reducer body, a protective component, and a hydraulic lifting component. A tunneling head is provided on one side of the reducer body, and a mounting base is provided on another side of the reducer body. The protective component is located on the outside of the reducer body and includes a fixed plate, a movable component, a protective baffle, a sealing arc block, and a square block. The hydraulic lifting component is rotatably connected to one side of the mounting base, and a rotating seat is provided below the hydraulic lifting component.
[0007] Furthermore, the fixing plate is fixedly connected to one side of the mounting base, and one side of the fixing plate is rotatably connected to a movable component, and the number of movable components is four, with the four movable components rotatably connected to the four sides of the fixing plate.

[0010] A tunneling machine includes a main body, a traveling unit, and a hydraulic push rod. The main body is located below a rotating base, and a dust suppression component is provided on one side of the upper part of the main body.

The traveling unit is located on the inner side of the lower end of the main body, and a transmission unit is provided on the inner side of the main body. The hydraulic push rod is located on both sides of the front end of the main body, and a shovel plate is rotatably connected to the front end of the hydraulic push rod.

A square block 405 is welded to the surface of the movable part 402, and the square blocks 405 are fixedly connected to each other by bolts. The hydraulic lifting part 5 is rotatably connected to one side of the mounting base 3, and a rotating seat 6 is provided below the hydraulic lifting part 5.
[0024] The specific operation is as follows: the operator can use the protective component 4 to protect the reducer body 1. The operator rotates the movable part 402 so that the sealing arc block 404 fixedly connected to the inner side of the movable part 402 is in close contact with the outer wall of one side of the tunneling head 2. Then, the square blocks 405 welded to the surface of the movable part 402 are fixed together with bolts, so that the protective component 4 is stably set on the outside of the reducer body 1, preventing liquid from seeping in and affecting the performance of the cutting reducer. At the same time, a filter screen is fixedly connected to the center of the movable part 402, and a protective baffle 403 is fixedly connected to the outer side of the movable part 402, ensuring the heat dissipation efficiency of the cutting reducer. This makes the operation of the tunneling machine more efficient, and the structure is simple and convenient for the operator to use the cutting reducer.

The support frame 801 is fixedly connected to one side of the upper part of the main body 7, and the water tank 802 is fixedly connected above the support frame 801. The pump 803 is positioned above the water tank 802, and a connecting hose 804 is fixedly connected to one side of the pump 803.

The side of the drain pipe 806 is fixedly connected to the atomizing nozzle 807. The outer sides of the water pump 805 and the drain pipe 806 are provided with support members 808, and the end of the support member 808 is welded to the outer wall of the water storage tank 802. The walking part 9 is located on the lower inner side of the main body 7, and the inner side of the main body 7 is provided with the transmission part 10.

[0026] The specific operation is as follows: When the tunneling machine is running, the dust suppression component 8 can be used to suppress the flying dust. The pump 803 draws liquid from the water storage tank 802, and the liquid enters the drain pipe 806 through the water pumping pipe 805 and the connecting hose 804. Then, the atomizing nozzle 807 fixedly connected to one side of the drain pipe 806 sprays the liquid in a mist, so that the mist liquid condenses with the flying dust, thereby achieving the purpose of dust suppression, ensuring the cleanliness of the tunneling machine during operation, and avoiding damage to the equipment and people caused by flying dust. The pitch angle of the tunneling head 2 can be adjusted by the hydraulic lifting part 5, and the lateral angle of the tunneling head 2 can be adjusted by the rotating seat 6. During the movement of the device by the traveling part 9, the broken stone is scooped up by the shovel part 12 and transported to the transmission part 10 through the transmission port 13. The transmission part 10 transports the stone to the rear of the device for processing. The structure is simple and convenient for the workers to use the tunneling machine.
[0027] In summary, this water-prevention cutting reducer and tunneling machine, based on... Figures 1-4The structure shown allows for the following operation of the tunneling machine: First, the operator can use the protective component 4 to protect the reducer body 1. The operator rotates the movable part 402, causing the sealing arc-shaped block 404 fixedly connected to the inner side of the movable part 402 to make tight contact with one side of the outer wall of the tunneling head 2. Then, bolts are used to fix the square blocks 405 welded to the surface of the movable part 402, thus ensuring that the protective component 4 is securely installed on the outside of the reducer body 1. During tunneling machine operation, the operator can use the dust suppression component 8 to suppress flying dust, and the pump 803 pumps water from the storage tank 802. Liquid extraction allows liquid to flow from the pumping pipe 805 through the connecting hose 804 into the drain pipe 806.

In addition, the pitch angle of the tunneling head 2 can be adjusted by the hydraulic lifting unit 5, and the lateral angle of the tunneling head 2 can be adjusted by the rotating seat 6. During the movement of the device by the traveling unit 9, the broken stone is scooped up by the shovel plate 12 and transported to the transmission unit 10 through the transmission port 13. The transmission unit 10 then transports the stone to the rear of the device for processing. The structure is simple and convenient for operators to use the tunneling machine.
