Description

Technical Field

[0001] The utility model belongs to the technical field of tunnel construction, and in particular relates to a self-propelled secondary lining concrete curing trolley for a tunnel. Background Art

[0002] In tunnel engineering, after the concrete of the second lining is demoulded, it should be kept warm and moisturized in time. If the maintenance is not timely, the water in the concrete will evaporate, resulting in dehydration, which will prevent the gel cement particles that have been formed from being fully hydrated and transformed into stable crystals. The cement particles lack sufficient adhesion, and the concrete surface will have flaky and powdery detachment. At the same time, if the water evaporates too early, the concrete will shrink and deform, and shrinkage cracks will appear, affecting the durability and integrity of the concrete. During the concrete maintenance period, the temperature of the concrete core should not exceed 60°C and should not exceed 65°C; the difference between the concrete core temperature and the surface temperature, and the surface temperature and the ambient temperature should not be greater than 20°C; the difference between the maintenance water temperature and the concrete surface temperature should not be greater than 15°C. When the ambient temperature is below 5°C, it is prohibited to sprinkle water on the concrete surface for maintenance, but insulation and moisturizing maintenance measures should be taken.

[0003] However, the tunnel secondary lining concrete curing device in the prior art is not easy to move, which reduces the curing efficiency. Utility Model Content

[0046] Example:

[0047] This embodiment provides a self-propelled tunnel secondary lining concrete curing trolley, which is used to solve the technical problem that the tunnel secondary lining concrete curing device in the prior art is not easy to move. The tunnel self-propelled secondary lining concrete curing trolley includes a base 1, a mounting frame 2, a spraying assembly, a driving assembly 4 and a guiding assembly 5, wherein:

[0048] The base 1 is a square structure.

[0049] The mounting frame 2 is fixedly mounted on the base 1 , and the mounting frame 2 is arc-shaped and adapted to the shape of the tunnel.

[0050] The spray assembly is installed on the mounting frame 2 and connected to the water source. The spray assembly is used to spray the curing liquid onto the concrete. The spray assembly is connected to the water source through a hose. The hose is provided with a control valve for controlling the water flow. In this way, through the setting of the mounting frame 2 adapted to the tunnel, it is easier for the spray assembly to evenly spray the curing liquid onto the second lining surface.

[0051] The driving assembly 4 is installed on the bottom wall of the base 1, and the driving assembly 4 is used to drive the base 1 to move. In this way, through the arrangement of the driving assembly 4, no human power is required, which saves time and effort.

[0052] The guide assembly 5 is installed on the bottom wall of the base 1 and is located in front of the driving assembly 4. The guide assembly 5 is used to drive the base 1 to turn. Through the setting of the guide assembly 5, no manual steering is required, which further reduces the time cost.

[0053] Through the above structure, when it is necessary to maintain the secondary lining concrete of the tunnel, the spraying assembly is first connected to the water source so that the spraying assembly sprays the maintenance liquid onto the secondary lining surface, and then the base 1 is driven to move forward through the driving assembly 4, so that the mounting frame 2 installed on the base 1 moves forward together with the spraying assembly. When turning is required, the guide assembly 5 is driven to make the base 1 turn, driving the mounting frame 2 and the spraying assembly to turn together. In this way, through the arrangement of the driving assembly 4 and the guide assembly 5, the tunnel self-propelled secondary lining concrete maintenance trolley provided by the utility model can move along the direction in which the tunnel extends, and the movement is more convenient, thereby improving the maintenance efficiency.

[0054] An optional implementation of this embodiment is as follows: the driving assembly 4 includes a driving wheel 41, a connecting rod 42, a worm wheel 43 and a worm 44, wherein:

[0055] There are two driving wheels 41 , and both driving wheels 41 are rotatably mounted on the bottom wall of the base 1 . Specifically, a first mounting groove is provided on the bottom wall of the base 1 , and the two driving wheels 41 are rotatably mounted on the left and right sides of the first mounting groove, respectively.

[0058] The worm 44 is rotatably mounted on the base 1 and meshes with the worm wheel 43. In this way, when the worm 44 rotates, it drives the worm wheel 43 to rotate together, so that the connecting rod 42 connected to the worm wheel 43 rotates synchronously, and further the two driving wheels 41 mounted at both ends of the connecting rod 42 rotate synchronously, so as to achieve the purpose of driving the base 1 to move forward.

[0059] Optionally, it further includes a driving member, one end of which is fixedly mounted on the base 1 and the other end is connected to the worm 44. The driving member is used to drive the worm 44 to rotate. In this way, through the setting of the driving member, it is easier to drive the worm 44 to rotate.

[0060] Optionally, the driving member is a first motor. Specifically, one end of the first motor is mounted on the side wall of the first installation groove. A circular groove is provided on the side of the first installation groove opposite to the first motor. The rotating shaft of the first motor is rotatably inserted into the circular groove, and the axis of the rotating shaft of the first motor is perpendicular to the axis of the connecting rod 42. In this way, by selecting the motor as the power source, the motor can provide stable rotational power and is easy to control. When the motor rotates forward, the base 1 moves forward; when the motor rotates backward, the base 1 moves backward.

[0061] An optional implementation manner of this embodiment is as follows: The guiding assembly 5 includes guiding wheels 51, rotating rods 52, mounting frames 53, first belt pulleys 54, transmission rods 55 and second belt pulleys 56, where:

[0062] The number of the guiding wheels 51 is two.

Specifically, second installation grooves are provided on the bottom wall of the base 1, and the two guiding wheels 51 are respectively rotatably mounted on the opposite side walls of the second installation grooves, and the axes of the two guiding wheels 51 are parallel to the axes of the two driving wheels 41.

[0063] The number of the rotating rods 52 is two. One ends of the two rotating rods 52 are respectively rotatably mounted on the two guiding wheels 51, and the other ends of the two rotating rods 52 extend in the direction of approaching each other.

[0064] The number of the mounting frames 53 is two, which are respectively fixedly mounted on the ends of the two rotating rods 52 away from the guiding wheels 51. The mounting frames 53 can be fixedly connected to the rotating rods 52 by welding or bonding or hot melting. Of course, they can also be integrally formed.

[0065] Optionally, the mounting frame 53 is in a C shape, and the openings of the two mounting frames 53 are arranged opposite to each other, that is, the mounting frame 53 includes a bottom plate, a top plate and a side plate. The bottom plate and the top plate are respectively fixedly mounted at the bottom end and the top end of the side plate, and the bottom plate and the top plate are located on the same side of the side plate.

[0066] There are two first pulleys 54 , which are fixedly mounted in two mounting frames 53 , respectively. The horizontal planes where the two first pulleys 54 are located are parallel to each other, that is, the horizontal planes where the two first pulleys 54 are located do not overlap.

[0067] The transmission rod 55 is rotatably mounted on the bottom wall of the base 1 , and the axis of the transmission rod 55 is perpendicular to the bottom wall of the base 1 , that is, one end of the transmission rod 55 is rotatably mounted on the bottom of the second mounting groove.

[0068] There are two second pulleys 56, and the two second pulleys 56 are both connected to the transmission rod 55 and are arranged at intervals. The two second pulleys 56 are arranged in a one-to-one correspondence with the two first pulleys 54. The two first pulleys 54 and the two second pulleys 56 are all driven by belts. In this way, through the setting of two sets of pulleys, when the transmission rod 55 rotates, it drives the two mounting frames 53 to rotate synchronously along the axes of the corresponding first pulleys 54, thereby causing the guide wheel 51 connected to the mounting frame 53 through the rotating rod 52 to deflect synchronously.

[0069] An optional implementation of this embodiment is as follows: it also includes a second motor 6, a driving wheel 7 and a driven wheel 8, wherein:

[0070] The second motor 6 is mounted on the bottom wall of the base 1 , with the rotating shaft of the second motor 6 facing downward. Specifically, the fixed end of the second motor 6 is mounted on the bottom of the second mounting groove.

[0071] The driving wheel 7 is connected to the rotating shaft of the second motor 6. When the motor rotates, the driving wheel 7 is driven to rotate synchronously.

[0072] The driven wheel 8 is connected to the transmission rod 55 and meshes with the driving wheel 7. When the driving wheel 7 rotates, the driven wheel 8 is driven to rotate together. The motor rotates forward and reverse, driving the guide wheel 51 to deflect in different directions.

[0073] An optional implementation of this embodiment is as follows: it also includes a water tank 9, which is installed on the base 1. The water tank 9 is connected to the spray assembly. In this way, the setting of the water tank 9 makes it easier to store the curing liquid.

[0074] Optionally, a water level sensor 10 is further included and installed in the water tank 9 . The water level sensor 10 is used to detect the amount of water in the water tank 9 .

[0075] Optionally, there are two water level sensors 10, both of which are installed in the water tank 9, and any water level sensor 10 is located above the other water level sensor 10. The two water level sensors 10 are set to detect the lowest water level and the highest water level in the water tank 9 respectively. When the water level in the water tank 9 is lower than the lowest water level, curing liquid is added to the water tank 9; when the water level in the water tank 9 is higher than the highest water level, the addition of curing liquid is stopped. In this way, through the setting of two water level sensors 10, it is easier to control the capacity of the curing liquid in the water tank 9.

[0076] An optional implementation of this embodiment is as follows: the spraying assembly includes multiple nozzles 3, and the multiple nozzles 3 are all installed on the mounting frame 2 and connected to the water tank 9. Through the arrangement of multiple nozzles 3, the curing liquid can be sprayed more evenly onto the second lining surface, and the spraying efficiency is improved.

[0077] The specific implementation methods described above further illustrate the purpose, technical solutions and beneficial effects of the utility model in detail. It should be understood that the above description is only the specific implementation method of the utility model and is not used to limit the protection scope of the utility model.
