Description

Technical Field

[0001] This utility model relates to the field of concrete curing equipment technology, and in particular to an automatic concrete curing device. Background Technology

[0002] In bridge construction, crash barriers are crucial structures for ensuring traffic safety, and their construction quality directly impacts the safety and durability of the bridge. After the concrete barriers are poured, their surface must be kept consistently moist during the curing period to ensure sufficient cement hydration and prevent problems such as cracking and insufficient strength caused by excessive water loss. Traditional guardrail maintenance mainly relies on manual spraying with water hoses. This method has the following significant drawbacks: First, it is labor-intensive and inefficient. Bridge guardrails are usually hundreds of meters or even kilometers long. Manual spraying requires operators to work at height for a long time (the guardrail is located on the outside of the bridge or on top of the central divider). They need to frequently move the water hose and control the spraying range. Each maintenance is time-consuming and labor-intensive. Especially in long-distance, multi-section construction, the labor cost is extremely high. Secondly, it is difficult to guarantee the uniformity of curing: manual operation is affected by factors such as fatigue and experience, which can easily lead to local missed spraying or excessive spraying, resulting in uneven drying and wetting of the guardrail surface and affecting the consistency of concrete strength; in addition, when spraying the exterior of the guardrail for maintenance, operators need to frequently bend over or move sideways, which also poses certain safety hazards. Therefore, there is an urgent need for an automatic concrete curing device that can move autonomously on top of the guardrail and automatically complete the spraying operation, so as to replace manual operation and achieve efficient, uniform and safe curing of bridge anti-collision concrete guardrails. Utility Model Content

[0003] The purpose of this invention is to provide an automatic concrete curing device that can replace manual labor in spraying and curing concrete guardrails, thereby ensuring work efficiency, reducing labor intensity, and guaranteeing curing quality.

[0005] Preferably, the limiting rod is provided with a limiting roller.

[0006] Preferably, the limiting roller is adjustablely mounted on the limiting rod via a screw.

[0007] Preferably, the limiting roller is a swivel wheel.

[0008] Preferably, the limiting rod on each side is movably connected to the water storage tank.

[0009] Preferably, the limiting rod is connected by a connecting rod, and the connecting rod is movably connected to a connecting plate disposed on the water storage tank.

[0010] Preferably, a positioning rod is elastically provided on one of the connecting plates on each side of the water storage tank, and positioning holes are symmetrically provided at the ends of the connecting rods.

[0011] Preferably, the connecting rod has a hollow structure, wherein one end of the connecting rod is rotatably connected to the diversion pipe; a water supply pipe is provided on the limiting rod, the water supply pipe is connected to the connecting rod, and the spray head is provided on the water supply pipe.

[0012] Preferably, the inner side of each limiting rod is provided with a receiving groove in the vertical direction, and the diverting water pipe is located in the receiving groove; the connecting rod is provided through the receiving groove, and the top of the diverting water pipe is connected to the connecting rod located in the receiving groove.

[0014] Compared with the prior art, the advantages of this utility model are as follows: This utility model uses a motor to drive the moving wheels, and the device can move autonomously along the top of the guardrail without manual pushing or pulling or hand-held water pipes. The coverage distance of a single maintenance can reach hundreds of meters (only the water in the storage tank needs to be replenished periodically), which greatly improves efficiency compared with manual operation, and is especially suitable for large-scale maintenance of long-distance bridge guardrails; In addition, the setting of limit rods on both sides of the water tank can guide the movement of the water tank, prevent the water tank from falling, and ensure the smooth progress of the spraying operation.

[0015] Figure 1 This is a schematic diagram of the structure of an embodiment of this application; Figure 2 for Figure 1 A magnified view of A in the middle. Detailed Implementation

[0016] The present invention will now be described clearly and completely with reference to the accompanying drawings and embodiments: like Figures 1 to 2As shown, the automatic concrete curing device of this utility model includes a water storage tank 1, a filter screen 2 inside the water storage tank 1 to filter the water flowing into the water storage tank 1 and prevent the spray head 3 from clogging, a water pump 4 on the water storage tank 1, the inlet end of the water pump 4 being connected to the inside of the water storage tank 1, and the outlet end of the water pump 4 being connected to a diversion pipe 5, on which the spray head 3 is installed; a movable wheel 6 is provided at the bottom of the water storage tank 1, the movable wheel 6 being arranged along the center line at the bottom of the water storage tank 1, one of the movable wheels 6 being driven by a motor 7, the motor 7 being connected to the movable wheel 6 through a reducer, the reducer housing being connected to the bottom support of the water storage tank 1 through a shock-absorbing rubber pad, which can effectively reduce transmission noise and vibration; multiple downward-extending limit rods 8 are provided on both sides of the water storage tank 1 along its length direction, the limit rods 8 being distributed on both sides of the concrete guardrail during operation, which can prevent the water storage tank 1 from falling during movement. When in operation, this utility model uses a motor 7 to drive the moving wheels 6, which can move the water storage tank 1 along the top of the concrete guardrail. There is no need for manual pushing or pulling or hand-held water pipes to follow. The coverage distance for a single maintenance can reach hundreds of meters. Only the water storage tank 1 needs to be replenished periodically. Compared with manual operation, the efficiency is greatly improved, and it is especially suitable for large-scale maintenance of long-distance bridge guardrails.

[0017] Furthermore, each limiting rod 8 is equipped with a limiting roller 9, preferably a caster wheel, which reduces resistance during movement. During operation, the limiting roller 9 contacts the side wall of the concrete guardrail, further enhancing the guiding effect on the water storage tank 1 and effectively preventing deviation during movement. The limiting roller 9 is adjustable on the limiting rod 8 via a screw 10. This configuration allows for adjustment of the distance between the limiting roller 9 and the concrete guardrail as needed, accommodating different sizes of concrete guardrails and expanding the applicability of this device.

[0018] Furthermore, each limiting rod 8 is movably connected to the water storage tank 1, so that when the water storage tank 1 is removed from the concrete guardrail, the limiting rod 8 can be folded upwards, and the water storage tank 1 can be moved to a designated position by using rollers to contact the ground, avoiding the time-consuming and laborious manual handling. Specifically, multiple limiting rods 8 on each side are connected by connecting rods 11, and the connecting rods 11 are movably connected to the connecting plates 12 set on the water storage tank 1. The two ends of the connecting rods 11 are rotatably connected to the connecting plates 12 through bearings. On one of the connecting plates 12 on each side of the water storage tank 1, a positioning rod 14 is elastically set by a spring 13. The end of the connecting rod 11 is symmetrically provided with positioning holes 15. The positioning rod 14 can be positioned by passing through the positioning holes 15 to ensure its stability. When it is necessary to fold the limiting rod 8 upwards, pull the positioning rod 14 to disengage it from the positioning hole 15. When the positioning hole 15 at the bottom of the connecting rod 11 rotates to the upper part, release the positioning rod 14 to let it enter the upper positioning hole 15.

[0019] Furthermore, the connecting rod 11 has a hollow structure, with one end rotatably connected to the diversion pipe 5, ensuring communication between the two while preventing the rotation of the limiting rod 8 from being restricted. A water supply pipe 16 is installed on the limiting rod 8, communicating with the connecting rod 11, and a spray head 3 is installed on the water supply pipe 16. This arrangement enables spray curing of the concrete guardrail sidewalls. The diversion pipe 5 is arranged in a U-shape outside the water storage tank 1, with a spray head 3 installed on the diversion pipe 5 at the front end of the water storage tank 1 to ensure spraying of the top of the concrete guardrail. Preferably, each limiting rod 8 has a vertically oriented receiving groove 17 on its inner side, with the diversion pipe located within the receiving groove 17; the connecting rod 11 passes through the receiving groove 17, and the top of the diversion pipe communicates with the connecting rod 11 located within the receiving groove 17.

[0020] This invention allows for the installation of a power distribution box on the water storage tank 1, housing a battery and a control module to enable remote control operation of the water storage tank 1. The battery directly powers the motor 7 and water pump 4, eliminating the need for the water storage tank 1 to be dragged along excessively long power lines during operation, thus improving operational safety to some extent. The control module, used to control the operation of the motor 7 and water pump 4, can utilize existing equipment.

[0021] In use, the water storage tank 1 is first placed on the solidified concrete guardrail, and then water is injected into it. After the water is injected, the motor 7 is started to drive the moving wheel 6 to rotate, thereby moving the water storage tank 1 on the concrete guardrail. At the same time, the water pump 4 is turned on to achieve spraying while moving. There is no need for manual pushing or pulling or holding the water pipe. Compared with manual operation, the efficiency is greatly improved, the operation is simple and the practicality is strong.
