[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0033] Example 1:

[0034] Reference Figure 1-6 This embodiment provides tunnel maintenance equipment, including a base plate 1. A water storage tank 2 is fixedly installed at the top center of the base plate 1. An automatic spraying mechanism is installed at one end of the water storage tank 2. The automatic spraying mechanism is connected to the water storage tank 2 and fixedly connected to the base plate 1. A slag collection trough 3 is installed at the other end of the water storage tank 2. The slag collection trough 3 is fixedly connected to the top of the base plate 1. A slag collection mechanism is movably installed on the side wall of the slag collection trough 3.

[0035] Furthermore, the water storage tank 2 is detachably equipped with a sealing cover 48, the bottom front end of the base plate 1 is equipped with casters 46, and the bottom rear end is equipped with wheels 47.

[0036] By setting up an automatic spraying mechanism, large-area, all-around water spraying can be achieved inside the tunnel, and mechanized automatic spraying can be realized, saving time and labor, greatly improving the efficiency of tunnel maintenance, and increasing the hardening speed of concrete. The set-up slag collection mechanism can simultaneously collect slag and clean the tunnel ground during the spraying and maintenance process, eliminating the need for additional workers to clean the ground. This integrates cleaning and maintenance processes, improving work efficiency, greatly shortening the tunnel construction cycle, and accelerating the tunnel construction progress.

[0037] The scheme is further optimized. The slag collection mechanism includes two parallel lifting rods 4. The top of the lifting rods 4 is rotatably connected to a connecting shaft 10. The connecting shaft 10 is fixedly connected to the top of the side wall of the slag collection trough 3. Several teeth 49 are fixedly connected to the side wall of the lifting rods 4 near the slag collection trough 3. An upper limit plate 8 is fixedly connected to the top of the two lifting rods 4. A fixed connecting rod 7 is fixedly connected to the middle of the two lifting rods 4. A lower limit plate 9 is fixedly connected to the bottom of the two lifting rods 4. A lifting part is slidably arranged on the two lifting rods 4. A rotating part is rotatably connected to the side of the lifting part away from the slag collection trough 3. A slag collection bucket 6 is fixedly connected to the rotating part. A lifting part is arranged between the fixed connecting rod 7 and the side wall of the slag collection trough 3.

[0038] The scheme is further optimized. The lifting part includes a lifting seat 5, which is slidably sleeved on two lifting rods 4. A lifting motor 16 is fixedly installed inside the lifting seat 5. The output shaft of the lifting motor 16 is fixedly connected to a lifting drive gear 17. The lifting drive gear 17 meshes with teeth 49. The rotating part is located on the side of the lifting seat 5 away from the slag collection trough 3.

[0039] The design is further optimized so that the rotating part includes a rotating frustum 18, which is rotatably mounted inside the lifting seat 5. An annular gear ring is fixedly connected to the outer wall of the rotating frustum 18 inside the lifting seat 5. A rotary motor 19 is also fixedly mounted inside the lifting seat 5. A rotary drive gear 20 is fixedly connected to the output shaft of the rotary motor 19. The rotary drive gear 20 meshes with the annular gear ring. The end of the rotating frustum 18 away from the annular gear ring is fixedly connected to the slag collection bucket 6.

[0040] The design is further optimized so that the lifting part includes a first hinge seat 11. One end of the first hinge seat 11 is fixedly connected to the outer wall of the slag collection trough 3. The other end of the first hinge seat 11 is hinged to one end of a telescopic cylinder 13 through a first hinge shaft 12. The piston end of the telescopic cylinder 13 is hinged to one end of a second hinge seat 14 through a second hinge shaft 15. The other end of the second hinge seat 14 is fixedly connected to a fixed connecting rod 7.

[0041] During the spraying and maintenance process, the lifting motor 16 drives the lifting drive gear 17 to rotate, thereby lowering the lifting seat 5 to the bottom of the lifting rod 4. Then, the rotary motor 19 drives the rotary drive gear 20 to rotate, which in turn drives the slag collection bucket 6 to rotate via the rotating platform 18, making the opening of the slag collection bucket 6 horizontally facing the direction of equipment movement. As the equipment moves forward, the slag collection bucket 6 gradually collects impurities from the tunnel floor. When a certain amount of impurities has been collected in the slag collection bucket 6, the equipment stops moving forward. At this time, the lifting motor 16 reverses, and the slag collection bucket 6 rises a certain distance via the lifting seat 5. Then, the rotary motor 19 reverses, adjusting the slag collection bucket 6 from a horizontal to a vertical position. Then, the lifting motor 16 continues to reverse, raising the slag collection bucket 6 to its highest position. Then, the lifting motor 16 stops working, and then the telescopic cylinder 13 extends, controlling the lifting rod 4 to rotate around the connecting shaft 10, causing the slag collection bucket 6 to tilt and pour the impurities collected in the slag collection bucket 6 into the slag collection trough 3. Then, the telescopic cylinder 13 shortens, and the lifting rod 4 returns to a vertical position. Then, by controlling the lifting motor 16 and the rotary motor 19 to rotate forward, the slag collection bucket 6 returns to the bottom to collect impurities again, and so on, repeating the cycle.

[0042] The scheme is further optimized. The automatic spraying mechanism includes a support rod 35. The bottom end of the support rod 35 is fixedly connected to the side wall of the base plate 1. The top end of the support rod 35 is fixedly connected to a support frame 36. The support frame 36 is fixedly connected to a vertical spraying part. The vertical spraying part is connected to the water storage tank 2. The vertical spraying part is also connected to two horizontal spraying parts. An adjustment part is provided between the horizontal spraying part and the side wall of the base plate 1.

[0043] The scheme is further optimized. The vertical spraying unit includes a lift pump 21, which is located inside the water storage tank 2. The outlet end of the lift pump 21 is connected to one end of the main water outlet pipe 22. The other end of the main water outlet pipe passes through the side wall of the water storage tank 2 and is connected to one end of a four-way connector 23. The other two ends of the four-way connector 23 are respectively connected to two horizontal spraying units. The third end of the four-way connector 23 is connected to one end of a second water outlet pipe 37. The other end of the second water outlet pipe 37 is connected to a second three-way connector 38. The other two ends of the second three-way connector 38 are respectively connected to a main arc-shaped support 39 and an extension pipe 41. The outer wall of the main arc-shaped support 39 is connected to several main nozzles 40. The extension pipe 41 is connected to a secondary arc-shaped support 42. The outer wall of the secondary arc-shaped support 42 is connected to several secondary nozzles 43. The main arc-shaped support 39 and the secondary arc-shaped support 42 are respectively fixedly connected to the side wall of the support frame 36 through several short connecting rods 45. The second water outlet pipe 37 is fixedly connected to the support rod 35 through a long connecting rod 44.

[0044] The scheme is further optimized by having two horizontal spray units symmetrically arranged on both sides of the base plate 1. Each horizontal spray unit includes a first water outlet pipe 24. One end of the first water outlet pipe 24 is connected to a four-way connector 23, and the other end of the first water outlet pipe 24 is connected to a first three-way connector 25. The other two ends of the first three-way connector 25 are respectively connected to a connecting hose 26 and a second water outlet branch pipe 32. The other end of the connecting hose 26 is connected to a first water outlet branch pipe 27. Several first nozzles 28 are connected to the side wall of the first water outlet branch pipe 27. An adjustment unit is fixedly connected to the outer side wall of the first water outlet branch pipe 27. Several second nozzles 33 are connected to the side wall of the second water outlet branch pipe 32. The other ends of the two second water outlet branch pipes 32 are connected. A fixing rod 34 is fixedly connected between the second water outlet branch pipe 32 and the side wall of the base plate 1.

[0045] The scheme is further optimized. The adjustment part includes a first connecting seat 29, which is fixedly connected to the outer wall of the first water outlet branch pipe 27. One end of the connecting rod 30 is rotatably connected to the first connecting seat 29, and the other end of the connecting rod 30 is rotatably connected to a second connecting seat 31. There are several second connecting seats 31, and all of the several second connecting seats 31 are fixedly connected to the side wall of the bottom plate 1.

[0046] The support frame 36, the main arc-shaped support 39, and the secondary arc-shaped support 42 are all the same shape.

[0047] When starting the spraying and curing process, first fill the water tank 2 with water, then extend the first outlet branch pipe 27 to an angle suitable for the tunnel dimensions, and insert the connecting rod 30 into the corresponding second connecting seat 31 to fix the first outlet branch pipe 27. Then, the spraying and curing work begins. The lift pump 21 pumps the water from the water tank 2 into the main outlet pipe 22, and then through the four-way connector 23, a portion of the water reaches the second outlet branch pipe 37, and through the second three-way connector 38, it enters the main arc support 39 and the secondary arc support 42 respectively. Water is sprayed from the main nozzle 40 and the auxiliary nozzle 43. The second tee joint 38 and the auxiliary arc bracket 42 are equipped with switch valves. When the water consumption is high, the valves are opened to allow the main nozzle 40 and the auxiliary nozzle 43 to spray water. When the water consumption is low, the valves are closed, and only the main nozzle 40 sprays water for curing. The other part of the water enters the first water outlet branch pipe 27 and the second water outlet branch pipe 32 respectively, and is sprayed out through the first nozzle 28 and the second nozzle 33. The sprayed water cures the tunnel ground on the one hand, and washes impurities to both sides of the equipment on the other hand, so that the slag collection bucket 6 can collect the impurities.

[0048] The movement mode of the entire equipment is determined according to the actual working conditions. It can be driven forward by a tractor or by the equipment itself with its own drive system.

[0049] A process method for tunnel maintenance equipment includes the following steps;

[0050] S1. Fill the water storage tank 2 with water and empty the slag collection trough 3. Then transfer the maintenance equipment to the starting end of the tunnel that needs maintenance.

[0051] S2. Adjust the unfolding angle of the first water outlet branch pipe 27 so that the spray range of the first nozzle 28 is adapted to the tunnel size;

[0052] S3. The maintenance equipment is driven forward by the power equipment to begin the maintenance of the tunnel;

[0053] S4. Collect the impurities generated during the maintenance process, and then continue forward to complete the maintenance work of the entire tunnel.

[0054] Example 2:

[0055] Reference Figure 7-8 The difference between this embodiment and Embodiment 1 is that the bottom end of the lifting part is fixedly connected to the top of the base plate 1, and the top of the lifting part is fixedly connected to the lifting plate 50. The water storage tank 2, the slag collection trough 3, and the automatic spraying mechanism are fixedly installed on the top of the lifting plate 50. The lifting part includes two parallel lower slide rails 52 and two parallel upper slide rails 53. Several hinges are movably arranged between the lower slide rails 52 and the upper slide rails 53. Each hinge includes a first lifting rod 56 and a second lifting rod 57 rotatably connected in the middle by a central connecting shaft 58. There are two first lifting rods 56 and two second lifting rods 57. Both ends of the first lifting rod 56 and the second lifting rod 57 are rotatably connected to the rotating shaft 59.

[0056] Furthermore, the support rod 35 is a telescopic structure, and the lifting rod 4 is a connecting extension structure.

[0057] In this embodiment, the equipment can spray and maintain tunnels with high ceilings. When maintaining the top of the tunnel, the lifting cylinder 51 is extended, causing the bottom end of the first lifting rod 56 to slide within the lower strip hole 54. During the sliding process, the angle between the first lifting rod 56 and the second lifting rod 57 decreases, thereby increasing the spraying height of the equipment.
