Technical Field

[0001] The utility model belongs to the technical field of concrete curing, and in particular relates to curing equipment for concrete pouring. Background Art

[0002] Concrete curing is to artificially create certain humidity and temperature conditions so that the newly poured concrete can harden and increase its strength normally or accelerate its hardening. After the concrete pouring work, while waiting for the concrete to harden, watering the hardened concrete floor is the main means of concrete curing. In this process, manual handheld watering pipes are usually used to maintain the concrete.

[0003] At present, in the prior art, in the process of spraying and curing a large area of ​​concrete floor, it is mainly done by manually holding a water spray pipe, and the length of the water pipe is limited, and the use site area is restricted. At the same time, when watering with a water pipe, a single water flow is often used, and the watering area per unit time is limited. At the same time, it is inconvenient to adjust the width of the water flow, which also leads to low efficiency in watering and curing the concrete floor. Utility Model Content

DETAILED DESCRIPTION

[0018] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0020] When the utility model is in use, water can be added to the water storage tank 4 through the water injection pipe 5, the tank cover 6 has a certain sealing performance, the horizontal pipe 7 can be rotated up and down, when the horizontal pipe 7 is erected, the valve assembly can stop the water spray head 8 from spraying water, and when the horizontal pipe 7 is rotated to be horizontal, the valve assembly can make the water spray head 8 discharge water.

[0021] The walking wheels 2 and the universal wheels 3 ensure that the maintenance equipment is not restricted by the site area when watering the concrete. The cross bar and the sprinkler head can expand the single concrete watering area of ​​the maintenance equipment and improve the watering efficiency and uniformity. At the same time, the valve assembly and the rotating cross bar can adjust the water flow width of the maintenance equipment during operation to improve flexibility. The pressurizing assembly can increase the internal pressure of the water storage tank 4, thereby increasing the flow rate of the sprinkler head 8, thereby further improving work efficiency.

[0022] The valve assembly includes two vertical pipes 9, and the number of the vertical pipes 9 is symmetrically distributed on the left and right sides. A notch 10 is opened on the side of the two vertical pipes 9 that are away from each other. A valve body sleeve 11 that is rotatably connected to the vertical pipe 9 is sleeved on the outer side of the notch 10, and the valve body sleeve 11 is tightly matched with the vertical pipe 9. The horizontal pipe 7 is connected to the valve body sleeve 11 and is communicated with the vertical pipe 9.

[0023] When the transverse tube 7 is in a horizontal state, the transverse tube 7 cooperates with the notch 10, and the transverse tube 7 and the vertical tube 9 are in a connected state. When the transverse tube 7 is in a vertical state, the transverse tube 7 and the notch 10 are misaligned, and the valve assembly is in an open circuit state.

[0024] The cooperation between the notch 10 and the valve body sleeve 11 realizes the on-off function of controlling the cross pipe 7 and makes the valve assembly simple in structure and operation, thereby improving the convenience of use.

[0025] The pressurizing assembly includes two groups of air pumps distributed on the left and right, with an air pump pipe 12 connected to the rear side of the air pump, which is connected to the top of the water tank 4 and communicates with the interior thereof. The air pump includes a cylinder body 13 and a piston rod 14, the piston rod 14 is slidably connected to the cylinder body 13 left and right, the cylinder body 13 is fixedly connected to the bottom of the cart 1, a crank shaft 16 is rotatably installed on the lower side of the cart 1, both ends of the crank shaft 16 are respectively connected to the two walking wheels 2 for transmission, a connecting rod 15 is hinged on the upper and lower sides of the front side of the piston rod 14, and the other end of the connecting rod 15 is connected to the crank shaft 16 for transmission.

[0026] When in use, the staff pushes the cart 1 forward, so that the running wheel 2 rotates to drive the crank shaft 16 to rotate, and the connecting rod 15 converts the circular motion of the crank shaft 16 into the forward and backward reciprocating motion of the piston rod 14. At this time, the air pump can pump air into the air pump pipe 12, thereby increasing the internal pressure of the water storage tank 4.

[0027] The connecting rod 15 enables the air pump to be linked with the running wheel 2, so that when the staff pushes the cart 1, the inside of the water pipe can be automatically pressurized without providing additional power, thus saving energy and reducing the cost of use.

[0028] The connection points of the crankshaft 16 and the two connecting rods 15 are in opposite directions.

[0029] The design of the connecting rod 15 and the crank shaft 16 connecting point in opposite directions can keep the running directions of the piston rods 14 inside the two air pumps opposite, so that the resistance of the air pump to the cart 1 when moving is smaller and more balanced, thereby improving user-friendliness.

[0030] Transparent observation windows 17 are vertically provided on both the front and rear sides of the water storage tank 4 .

[0031] A pressure relief valve 18 communicating with the interior of the water storage tank 4 is installed on the top of the water storage tank 4 .

[0032] The transparent observation windows 17 on both sides make it convenient for the staff to observe the water volume inside the water tank 4, which is convenient for use. When the internal pressure of the water tank 4 is too high, the pressure relief valve 18 can remove excess air from the water tank 4, thereby protecting the water tank 4, improving the reliability of the equipment and extending its service life.
