Description

Technical Field

[0001] The utility model relates to the technical field of road and bridge construction, and more specifically, to a self-propelled intelligent spray guardrail health-preserving device. Background Art

[0002] Concrete curing is to create certain humidity and temperature conditions artificially so that the newly poured concrete can harden normally or accelerate its strength growth. The gradual hardening and strength growth of concrete is the result of cement hydration, and cement hydration requires certain temperature and humidity conditions; after concrete pouring, the air is dry, and if curing is not carried out in time, the water in the concrete will evaporate too quickly, resulting in large shrinkage deformation and shrinkage cracks. Therefore, the timeliness of curing in the initial stage after concrete pouring is very important.

[0003] Currently, in the construction, most of the bridge anti-collision guardrails use artificial curing or bridge anti-collision guardrail concrete curing equipment. Artificial curing is not timely and in place. Existing curing equipment often has problems such as trolley derailment and water pipe blockage. In addition, the curing equipment does not have a sensing system and cannot automatically cure, and it is often prone to water shortage and empty car operation. Whether it is artificial curing or existing curing equipment, it is easy to have untimely local concrete curing, which may cause the concrete strength of the anti-collision guardrail to fail to meet the design requirements and cracks on the appearance. In addition, the curing equipment in the prior art is generally powered by external wiring, which is easy to hang and break, posing a safety hazard. Utility Model Content

[0038] It should be noted that like reference numerals and letters refer to similar items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0039] The utility model embodiment provides a self-propelled intelligent spray guardrail health device, referring to Figure 1 and Figure 2 As shown, the embodiment of the utility model provides a self-propelled intelligent spray guardrail health device, including: a walking device 10 and a spray device 20 arranged on the walking device 10;

[0040] The traveling device 10 includes a truss 11, a traveling wheel 12, a positioning wheel 13 and a power device 14;

[0041] The truss 11 includes a plurality of supporting legs 111 and a supporting frame 112 connected to the top of the plurality of supporting legs 111;

[0042] The walking wheel 12 is arranged on the supporting frame 112 and moves on the top of the guardrail 00, and the positioning wheel 13 is arranged on the supporting leg 111 and moves on the side wall of the guardrail 00;

[0043] The power device 14 is electrically connected to the running wheel 12 to drive the running wheel 12 to move;

[0044] The spray device 20 includes a water storage tank 21 disposed on the top of the support frame 112 and a spray pipe 22 disposed on the support leg 111;

[0045] One end of the spray pipe 22 is connected to the water tank 21 , and the other end points to the guardrail 00 .

[0046] It is understandable that the self-propelled intelligent spray guardrail health-care device includes a walking device 10 and a spraying device 20. The walking device 10 is used to move along the guardrail 00, and the spraying device 20 sprays and maintains the guardrail 00.

[0047] Specifically, the walking device 10 includes a truss 11, which is erected on the guardrail 00 and is a carrier of other components. The walking device 10 also includes a walking wheel 12, a positioning wheel 12 and a power device 14. The power device 14 is electrically connected to the walking wheel 12 to provide power to the walking wheel 12 and drive it to move along the guardrail 00. The positioning wheel 13 is used to stabilize the device and prevent it from tipping over.

[0048] It should be noted that the power device 14 can be a battery assembly, which can be directly used to power the walking wheel 12. The health-preserving device is self-powered and does not require an external power supply. Therefore, no external wiring is required, which avoids the problem of the power cord being easily hung or torn in the prior art, which poses a safety hazard.

[0049] Furthermore, the truss 11 includes a support leg 111 and a support frame 112, and the plurality of support legs 111 are connected to the support frame 112. The support frame 112 is located at the top of the guardrail 00, and the support legs 111 are located at both sides of the guardrail 00. The walking wheels 12 are arranged on the truss 11, specifically, on the support frame 112, and the positioning wheels 13 are arranged on the support legs 111 located at both sides of the guardrail 00.

[0050] Furthermore, the spray device 20 includes a water tank 21 and a spray pipe 22. The water tank 21 is arranged on the top of the support frame 112 and moves under the drive of the walking device 10. The spray pipe 22 is arranged on the support leg 111. One end of the spray pipe 22 is connected to the water tank 21, and the other end points to the guardrail 00. When the walking device 10 drives the entire device to move, the spray pipe 22 sprays the liquid in the water tank 21 onto the side wall of the guardrail 00 to maintain the guardrail 00.

[0051] The embodiment provided by the utility model realizes unmanned, intelligent and automatic curing of the guardrail by driving the spraying device through the walking device capable of automatically moving, which is highly efficient, can effectively inhibit the generation of cracks, and promote the formation of early strength of concrete. In addition, the surface of the concrete is kept moist continuously and evenly, which truly meets the requirements of continuous moist curing, saves labor and energy, ensures safety, and reduces curing costs.

[0052] In another optional embodiment provided by the present utility model, continue to refer to Figure 1 and Figure 2 As shown, the support frame 112 is rectangular, and a plurality of support legs 111 are connected to two opposite sides of the support frame 112 .

[0053] It can be understood that the support frame 112 is the bearing mechanism of the entire device. It is a flat rectangle, with the top supporting the water tank 21 and the bottom connected to the walking wheel 12 to drive the device to move.

[0054] The plurality of support legs 111 are connected to two opposite sides of the support frame 112, where the two sides refer to the sides of the support frame 112 located in the extending direction of the guardrail 00. The plurality of support legs 111 are symmetrically arranged.

[0055] In another optional embodiment provided by the present invention, the running wheel 12 is arranged at the symmetry center of the support frame 112, and the moving direction of the running wheel 12 is the same as the extension direction of the guardrail 00.

[0056] It is understandable that the running wheel 12 is disposed at the bottom of the support frame 112 and is located on the symmetric center line. The running wheel 12 may include a plurality of running wheels, all of which are disposed along the symmetric center of the support frame 112. When in use, the running wheel 12 is located at the top of the guardrail 00 and moves along the extension direction of the guardrail 00. The wheel width of the running wheel 12 is not greater than the width of the top of the guardrail 00.

[0057] In another optional embodiment provided by the present invention, at least two positioning wheels 13 are connected to any supporting leg 111 ; and the plurality of positioning wheels 13 are arranged at intervals along the extending direction of the supporting leg 111 .

[0058] It can be understood that the positioning wheels 13 are used for stabilizing the device, which are connected to the support legs 111, and any support leg 111 includes at least two positioning wheels 13. The multiple positioning wheels 13 are arranged upward from the bottom of the support leg 111, and different positioning wheels 13 on the same support leg 111 are in contact with different heights of the side wall of the guardrail 00.

[0059] In another optional embodiment provided by the present utility model, the positioning wheel 13 is connected to the support leg 111 through a horizontally arranged support rod 15;

[0060] The support rod 15 is retracted in the horizontal direction until the positioning wheel 13 contacts the side wall of the guardrail 00 .

[0061] It is understandable that the support rod 15 is used to connect the positioning wheel 13 and the support leg 111. Specifically, a threaded hole is provided on the support leg 111, and the support rod 15 can be a threaded rod. The support rod 15 passes through the threaded hole of the support leg 111 and can be screwed in or out. One end of the support 15 is connected to the positioning wheel 13, and the other end can be connected to the handle. By holding the handle to screw the support rod 111 in or out, the positioning wheel 13 is driven to move in the horizontal direction until the positioning wheel 13 lightly contacts the side wall of the guardrail 00. During the movement of the protection device, the positioning wheel 13 slides on the side wall of the guardrail 00, which can not only improve the smoothness of the movement, but also ensure that the device does not tip over in the horizontal direction.

[0062] In another optional embodiment provided by the present utility model, a water pump 23 is provided in the water storage tank 21, and the water pump 23 is connected to one end of the spray pipe 22;

[0063] The water pump 23 is electrically connected to the power device 14 .

[0064] It is understandable that the water pump 23 disposed in the water tank 21 and one end of the spray pipe 22 pumps the liquid in the water tank 21 into the spray pipe 22. It is important that the water pump 23 is electrically connected to the power device 14, that is, the water pump 23 and the traveling device 10 share a power supply system. When the traveling device 10 stops moving, the water pump 23 stops working and the spraying stops; when the water pump 23 stops working, the traveling device 10 stops moving. In this way, it can prevent the device from repeatedly spraying at the same position of the guardrail 00, and it can also prevent the guardrail 00 from being moved away without being sprayed. This design improves the intelligence of the device.

[0065] In another optional embodiment provided by the present utility model, the spray pipe 22 includes a plurality of spray pipes, at least one spray pipe 22 is arranged along the bottom of the support frame 112, and at least one spray pipe 22 is arranged along the extension direction of the support leg 111;

[0066] Any spray pipe 22 is provided with a plurality of spray heads 221 , and the plurality of spray heads 221 are arranged at intervals along the length direction of the spray pipe 22 .

[0067] It can be understood that the spray pipe 22 is arranged along the bottom of the support frame 112, and its extension direction can be the same as the extension direction of the guardrail 00, and is used to spray the top of the guardrail 00. The spray pipe 22 is arranged along the extension direction of the support leg 111. Since the support leg 111 includes multiple spray pipes 22, multiple spray pipes 22 can also be arranged, and the spray pipes 22 are also symmetrically arranged on both sides of the guardrail 00, and are used to spray the side walls of the guardrail 00.

[0068] Multiple nozzles 221 can be arranged along the length direction of the spray pipe 22, and the nozzles 221 are used to discharge water. During the movement of the device, the top and both sides of the guardrail 00 can be sprayed for health care. At the same time, the same position of the guardrail 00 can receive multiple sprays to ensure that the guardrail 00 is completely wetted and the health care effect is ensured.

[0069] In another optional embodiment provided by the utility model, it also includes a temperature and humidity sensor;

[0070] The temperature and humidity sensor is electrically connected to the water pump 23 .

[0071] It is understandable that the temperature and humidity sensor can be set on the outer wall of the water tank 21, pointing to the direction of the guardrail 00. And the temperature and humidity sensor is electrically connected to the water pump 23. Specifically, the temperature and humidity sensor obtains the temperature and humidity parameters of the guardrail 00. When it is lower than the preset value, it sends an operation instruction to the spray device 20, that is, the water pump 23 starts to work, pumps liquid into the spray pipe 22, starts spraying, and at the same time, the walking device 10 starts to move. On the contrary, when the temperature and humidity parameters of the guardrail 00 obtained by the temperature and humidity sensor are higher than or lower than the preset value, the device does not start, which improves the intelligence of the oxidation of the guardrail 00.

[0072] In another optional embodiment provided by the present utility model, a water level detector is provided in the water storage tank 21;

[0073] The water level detector is electrically connected to the power device 14 .

[0074] It is understandable that the water tank 21 is provided with a water level detector for detecting the water level in the water tank 21. The water level detector is electrically connected to the power device 14, and when the water level detector detects that the water level in the water tank 21 is lower than a preset value, a stop instruction is issued to the power device 14, and the walking device 10 and the spraying device 20 stop synchronously.

[0075] Furthermore, an alarm device may be provided. When the water level detector detects that the water level in the water tank 21 is lower than a preset value, the alarm device sounds an alarm to prompt the engineering staff to add liquid to the water tank 21 in time, thereby improving the intelligence of the device.

[0076] In another optional embodiment provided by the utility model, it also includes an infrared sensing device;

[0077] The infrared sensing devices are arranged at both ends of the water tank 21 along the extending direction of the guardrail and are electrically connected to the power device 14 .

[0078] It is understandable that the infrared sensing device disposed outside the water tank 21 controls the movement of the device by identifying whether there are obstacles in the moving direction on the guardrail 00. Under the action of the infrared limiter and the travel switch, the device automatically returns after traveling to a certain distance from the end of the guardrail 00 to avoid collision damage to the device. The device repeatedly moves between the two ends of the guardrail 00 to fully spray and maintain the guardrail 00 until it is manually operated, the wet temperature reaches the standard, or the water level drops to a preset value, and the device stops.

[0079] In summary, the self-propelled intelligent spray guardrail health-preserving device provided by the utility model achieves at least the following beneficial effects:

[0080] The embodiment provided by the utility model realizes unmanned, intelligent and automatic curing of the guardrail by driving the spraying device through the walking device capable of automatically moving, which is highly efficient, can effectively inhibit the generation of cracks, and promote the formation of early strength of concrete. In addition, the surface of the concrete is kept moist continuously and evenly, which truly meets the requirements of continuous moist curing, saves labor and energy, ensures safety, and reduces curing costs.
