Description

Technical Field

[0001] This utility model relates to the field of fire prevention construction equipment technology, specifically a fire prevention construction equipment for highway tunnels. Background Technology

[0002] Fireproof construction equipment for highway tunnels refers to specialized equipment used for applying fireproof coatings inside tunnels. This equipment is mainly used to ensure fire protection of surfaces such as tunnel walls, roof slabs, and floor slabs to improve tunnel safety, and primarily refers to equipment for spraying fireproof coatings.

[0003] Existing Chinese patent document CN219808939U discloses a fireproof construction device for highway tunnels, including a support frame with a base installed at the bottom. Multiple construction platforms are mounted on the support frame, with the height of the platforms gradually increasing from left to right. Each construction platform has a ladder on its side, and anti-fouling grooves are symmetrically arranged on both sides of the support frame. The base is installed at the bottom of the support frame, and roller frames are connected to the four corners of the base. Rollers are connected inside the roller frames. The trolley is highly flexible, eliminating the need for manual pushing. It can be moved by a motor and its direction can be adjusted, facilitating independent operation and improving construction efficiency. However, this fireproof construction device for highway tunnels still has shortcomings: its construction platform structure provides a platform for workers to manually climb and spray fireproof coating. While spraying, operators also need to drive the trolley and control its movement. The construction platform equipment, which requires climbing and lacks a protective structure, cannot ensure the personal safety of operators during movement, making it difficult to meet practical usage needs. Utility Model Content

[0004] The purpose of this utility model is to solve the problem that the above-mentioned fire prevention construction device for highway tunnels uses a construction platform structure to provide a platform for construction personnel to manually climb and spray fireproof coating. The operator also needs to drive the platform vehicle to control the direction of movement while performing the spraying operation. The construction platform equipment that requires climbing and has no protective structure cannot ensure the personal safety of the operator when moving, and it is difficult to meet the actual use needs. Therefore, this utility model provides a fire prevention construction device for highway tunnels.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fireproof construction device for highway tunnels, comprising: a drivable mobile vehicle and a rear door; two sets of triangular fixing blocks are symmetrically fixed to one side of the drivable mobile vehicle; a lifting frame one and a lifting frame two are symmetrically arranged on both sides of the drivable mobile vehicle via the triangular fixing blocks; a servo motor is fixed to the bottom end of the lifting frame one; a rotating screw is provided at the output end of the servo motor; a lifting slider is slidably connected inside the lifting frame one; and a rotating screw is provided through one end of the lifting slider. The lifting slider is fixedly connected to a spray gun bracket on one side, and a side wall spray head is fixedly snapped onto the top of the spray gun bracket. A storage cylinder is fixedly mounted inside the drivable mobile vehicle. A side wall suction pump is provided on the top surface of the storage cylinder, and the side wall suction pump is connected to a side wall connecting pipe. The top of the storage cylinder is provided with a feed inlet and the bottom of the side is provided with a discharge outlet. A top wall suction pump is provided at the other end of the top surface of the storage cylinder, and the top wall suction pump is connected to a top wall connecting pipe. A top wall spray head is connected to the end of the top wall connecting pipe.

[0006] As a further embodiment of this utility model: the rotating screw is adapted to the specifications of the rotating screw hole, and one end of the side wall connecting pipe extends into the bottom of the storage cylinder and is connected to the side wall suction pump and the side wall spray head.

[0007] As a further improvement of this utility model: the second lifting frame is also fixedly installed on the other side of the drivable mobile vehicle by a triangular fixing block, and the second lifting frame is equipped with the same number and specifications of servo motors and their connection structures as the first lifting frame.

[0008] As a further embodiment of this utility model: the second storage cylinder is also provided with the same number and specifications of side wall suction pumps, side wall connecting pipes, inlet and outlet structures as the first storage cylinder, and the end of the side wall connecting pipe of the second storage cylinder is connected to the side wall spray head in the second lifting frame.

[0009] As a further improvement of this utility model: the top ends of the first and second lifting frames are fixed with the same set of connecting plates to stabilize their upright and installation states, and the top wall spray head is embedded in the center of the connecting plate and the output direction is towards the tunnel top wall.

[0010] As a further embodiment of this utility model: a base frame is fixedly connected to the bottom of the front end of the drivable mobile vehicle, a drive motor is fixedly connected to one side of the base frame, and a sweeping roller is horizontally mounted inside the base frame. One end of the sweeping roller is fixedly connected to the end of the output shaft of the drive motor to achieve rolling sweeping of gravel and debris on the ground.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. In this utility model, when the servo motor is started, the rotating screw at the output end of the servo motor begins to rotate. Since the rotating screw is compatible with the specifications of the rotating screw hole on the lifting slider, the rotation of the rotating screw drives the lifting slider to slide within the lifting frame one. The spray bracket fixed to one side of the lifting slider rises or falls with the movement of the lifting slider, thereby adjusting the height of the side wall spray head to adapt to the construction needs of tunnel side walls of different heights. It can also cooperate with the smooth movement of the drivable mobile vehicle to carry out fireproof coating spraying operation row by row. The operation is time-saving and labor-saving, and the spraying accuracy is accurate. The top wall suction pump at the other end of the top surface of the storage cylinder one draws out the fireproof coating through the top wall connecting pipe and delivers it to the top wall spray head. The top of the lifting frame one and the lifting frame two are fixed with the same set of connecting plates. The top wall spray head is embedded in the center of the connecting plate and the output direction faces the tunnel top wall. When the side wall spraying is completed or the top wall spraying operation is carried out alone, the top wall spray head can cooperate with the smooth movement of the drivable mobile vehicle to spray fireproof coating on the tunnel top wall.

[0013] 2. When driving the vehicle, start the drive motor at the bottom of the front end of the drivable vehicle. The output shaft of the drive motor drives the cleaning roller to rotate. The cleaning roller rolls laterally inside the base frame, thereby cleaning up the gravel and debris on the ground. This provides a relatively clean ground environment for subsequent construction or equipment movement, and avoids gravel causing deviation and bumps in the driving route, which would affect the spraying effect.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. The embodiments of this utility model will be described below based on its overall structure.

[0023] Reference Figures 1 to 6In this embodiment of the utility model, a fireproof construction device for highway tunnels includes: a drivable mobile vehicle 1 and a rear door 2. Two sets of triangular fixing blocks 3 are symmetrically fixed to one side of the drivable mobile vehicle 1. Lifting frames 1-4 and 2-16 are symmetrically arranged on both sides of the drivable mobile vehicle 1 through the triangular fixing blocks 3. A servo motor 5 is fixed to the bottom end of the lifting frame 1-4. A rotating screw 6 is provided at the output end of the servo motor 5. A lifting slider 7 is slidably connected inside the lifting frame 1-4. A rotating screw hole 8 is opened through one end of the lifting slider 7. A rotating screw hole 8 is fixed to one side of the lifting slider 7. There is a spray gun bracket 9, and a side wall spray head 10 is fixedly attached to the top of the spray gun bracket 9. The interior of the drivable mobile vehicle 1 carries a storage cylinder 12. A side wall suction pump 13 is installed on the top surface of the storage cylinder 12. The side wall suction pump 13 is connected to a side wall connecting pipe 11. The top of the storage cylinder 12 is provided with a feed port 14 and the bottom side is provided with a discharge port 15. The other end of the top surface of the storage cylinder 12 is provided with a top wall suction pump 18. The top wall suction pump 18 is connected to a top wall connecting pipe 19. The end of the top wall connecting pipe 19 is connected to a top wall spray head 20.

[0024] To clarify, the driver's position on the drivable mobile vehicle 1 in this application is equipped with a protective shield (not shown in the figure) to protect the driver and prevent fire-retardant coating from falling onto the driver.

[0025] Reference Figures 1 to 3 The rotating screw 6 is compatible with the rotating screw hole 8. One end of the side wall connecting pipe 11 extends into the bottom of the storage cylinder 12 and connects the side wall suction pump 13 and the side wall spray head 10. The second lifting frame 16 is also fixedly installed on the other side of the drivable mobile vehicle 1 by the triangular fixing block 3. The second lifting frame 16 is equipped with the same number and specifications of servo motors 5 and their connection structures as the first lifting frame 4.

[0026] Using the above scheme: The servo motor 5 is started, and the rotating screw 6 at the output end of the servo motor 5 begins to rotate. Since the rotating screw 6 is compatible with the rotating screw hole 8 on the lifting slider 7, the rotation of the rotating screw 6 drives the lifting slider 7 to slide within the lifting frame 4. The spray bracket 9 fixed to one side of the lifting slider 7 rises or falls with the movement of the lifting slider 7, thereby adjusting the height of the side wall spray head 10 to meet the construction needs of tunnel side walls at different heights. It can also be used in conjunction with the smooth movement of the drivable mobile vehicle 1 to carry out fireproof coating spraying operations row by row. The operation is time-saving, labor-saving and the spraying accuracy is accurate.

[0027] Reference Figure 4 The storage cylinder 2 17 is also equipped with the same number and specifications of side wall suction pump 13, side wall connecting pipe 11, inlet 14 and outlet 15 as the storage cylinder 1 12. The end of the side wall connecting pipe 11 of the storage cylinder 2 17 is connected to the side wall spray head 10 in the lifting frame 2 16.

[0028] The above scheme is adopted: the storage cylinder 12 stores fire-retardant coating, and the side wall suction pump 13 extracts the fire-retardant coating inside the storage cylinder 12 through the side wall connecting pipe 11 and delivers it to the side wall spray head 10, thereby spraying the tunnel side wall. The lifting frame 16 is set up the same as the lifting frame 4, and the storage cylinder 17 is the same as the storage cylinder 12 in terms of basic structure. The end of the side wall connecting pipe 11 of the storage cylinder 17 is connected to the side wall spray head 10 in the lifting frame 16. It can spray the side walls on both sides of the tunnel separately as the drivable mobile vehicle moves left and right, thereby improving construction efficiency.

[0029] Reference Figure 2 and Figure 4 The top of the lifting frame 14 and the lifting frame 26 are fixed with the same set of connecting plates 21 to stabilize their upright and installation state. The top wall spray head 20 is embedded in the center of the connecting plate 21 and the output direction is towards the tunnel top wall.

[0030] Using the above scheme: The top wall suction pump 18 at the other end of the top surface of the storage cylinder 12 draws out the fireproof coating through the top wall connecting pipe 19 and delivers it to the top wall spray head 20. The top of the lifting frame 1 4 and the lifting frame 2 16 are fixed with the same set of connecting plates 21. The top wall spray head 20 is embedded in the center of the connecting plate 21 and the output direction is towards the tunnel top wall. When the side wall spraying is completed or the top wall spraying operation is carried out alone, the top wall spray head 20 can cooperate with the smooth movement of the drivable mobile vehicle 1 to spray the fireproof coating on the tunnel top wall.

[0031] Reference Figure 5 and Figure 6 The drivable mobile vehicle 1 has a base frame 22 fixed to the bottom of the front end. A drive motor 23 is fixed to one side of the base frame 22. A sweeping roller 24 is horizontally mounted inside the base frame 22. One end of the sweeping roller 24 is fixed to the end of the output shaft of the drive motor 23 to achieve rolling sweeping of gravel and debris on the ground.

[0032] The above solution is adopted: When driving, the drive motor 23 at the bottom of the front end of the drivable mobile vehicle 1 is started. The output shaft of the drive motor 23 drives the cleaning roller 24 to rotate. The cleaning roller 24 rolls laterally in the base frame 22, thereby cleaning up the gravel and debris on the ground, providing a relatively clean ground environment for subsequent construction or equipment movement, and avoiding gravel causing deviation and bumps in the driving route, which would affect the spraying effect.

[0033] The working principle of this utility model is as follows: During use, the operator drives the drivable mobile vehicle 1 into the tunnel construction area. The drivable mobile vehicle 1, in conjunction with the spraying structure, performs a non-altitude mechanical spraying operation. The servo motor 5 is started, and the rotating screw 6 at the output end of the servo motor 5 begins to rotate. Since the rotating screw 6 is compatible with the rotating screw hole 8 on the lifting slider 7, the rotation of the rotating screw 6 causes the lifting slider 7 to slide within the lifting frame 4. The spray nozzle bracket 9 fixed to one side of the lifting slider 7 rises or falls as the lifting slider 7 moves, thus… The height of the sidewall spray head 10 is adjusted to adapt to the construction needs of tunnel sidewalls at different heights. It can also be used in conjunction with the smooth movement of the drivable mobile vehicle 1 to spray fire-retardant coating row by row, saving time and effort while ensuring accurate spraying. The storage cylinder 12 stores fire-retardant coating. The sidewall suction pump 13 extracts the fire-retardant coating from the storage cylinder 12 through the sidewall connecting pipe 11 and delivers it to the sidewall spray head 10 for spraying the tunnel sidewall. The lifting frame 16 is identical to the lifting frame 4, and the storage cylinder 17 has the same basic structure as the storage cylinder 12. Similarly, the end of the side wall connecting pipe 11 of the storage cylinder 2 17 is connected to the side wall spraying head 10 in the lifting frame 2 16, which can spray the side walls on both sides of the tunnel separately as the drivable mobile vehicle moves left and right, improving construction efficiency; the top wall suction pump 18 at the other end of the top surface of the storage cylinder 1 12 draws the fireproof coating through the top wall connecting pipe 19 and delivers it to the top wall spraying head 20. The top of the lifting frame 1 4 and the lifting frame 2 16 are fixed with the same set of connecting plates 21. The top wall spraying head 20 is embedded in the center of the connecting plate 21 and the output direction is towards the tunnel top wall. When the side wall is completed, the spraying head 10 can be sprayed on both sides of the tunnel. When spraying the tunnel walls or performing roof spraying operations separately, the roof spray head 20 can be used in conjunction with the smooth movement of the drivable mobile vehicle 1 to spray fireproof coating on the tunnel roof. When driving, the drive motor 23 at the bottom of the front end of the drivable mobile vehicle 1 is started. The output shaft of the drive motor 23 drives the cleaning roller 24 to rotate. The cleaning roller 24 rolls laterally within the base frame 22, thereby cleaning up the gravel and debris on the ground, providing a relatively clean ground environment for subsequent construction or equipment movement, and avoiding gravel causing deviation and bumps in the driving route, which would affect the spraying effect.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
