Description

Technical Field

[0001] This utility model belongs to the field of concrete curing technology, and in particular relates to a concrete pavement curing device. Background Technology

[0002] Concrete pavement generally consists of four parts: subgrade, base course, subbase, and surface course. The main material of the surface course is concrete, which is generally required to be wear-resistant, smooth, non-slip, and strong. After the concrete pavement is completed, water needs to be sprayed on the pavement for curing.

[0003] Currently, the spraying components of existing concrete pavement maintenance devices are usually fixed mechanisms with non-adjustable spraying coverage. The maintenance device needs to move back and forth frequently to achieve full coverage spraying, resulting in low work efficiency. When the road surface is narrow, the spraying range may exceed the road boundary, causing unnecessary spillage of maintenance water. This not only wastes water resources but may also have adverse effects on the surrounding environment (such as shoulder vegetation and municipal facilities).

[0004] To address the aforementioned problems, this application proposes a concrete pavement curing device. Utility Model Content

[0005] The purpose of this invention is to provide a concrete pavement maintenance device that solves the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model is a concrete pavement maintenance device, including a movable base with a water tank fixed on the top surface and multiple movable wheels installed at the bottom of the movable base, and two connecting seats respectively set above two spray pipes. The top of the spray pipe is fixed with a fixed seat that cooperates with the connecting slot of the connecting seat. The connecting seat is provided with two inserts, and the inserts are inserted into slots opened on the top surface of the fixed seat. Two rotating shafts are fixed at their bottom ends to the two connecting seats respectively. The bottom end of the spray pipe is connected to multiple nozzles. The rotating shafts are used to drive the spray pipe to rotate.

[0008] Furthermore, one side of the movable base is fixedly connected to the fixed shell by two fixing blocks, and the fixed shell is provided with two meshing gears.

The lower end of the rotating shaft passes through the bottom end of the fixed shell and is rotatably connected to the fixed shell. The top surface of the fixed shell is provided with a motor whose output end is fixedly connected to the top end of the rotating shaft.

[0009] Furthermore, the connecting seat has two receiving grooves communicating with the connecting groove, and the receiving grooves are used to receive the insert block. The cavity of the connecting seat has two moving blocks. The top of the insert block is fixed with a smooth rod that is slidably connected to the connecting seat. The moving block and the smooth rod are respectively fixed with hinge seats and the two ends of the connecting rod.

[0014] Furthermore, a connecting ring is fixed to the end of the connecting hose, and the outer wall of the connecting ring is flared. The diameter of the connecting ring at the end away from the connecting hose is larger than the diameter of the connecting ring at the end near the connecting hose.

[0015] This utility model has the following beneficial effects:

[0016] This utility model achieves quick locking and unlocking of the spray pipe and connector through the plug-in structure of the plug and slot. When the spray pipe needs to be repaired or replaced, it can be quickly disassembled, simplifying the maintenance process and reducing equipment downtime.

[0017] This invention uses a rotating shaft to drive the connecting seat to rotate, and further uses a fixed seat to drive the spray pipe to rotate, thereby adjusting the spray coverage area of ​​the nozzle and adapting to the maintenance needs of roads of different widths.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around" and other terms indicating orientation or positional relationship are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0030] Please see Figure 1 - Figure 6 As shown, this utility model is a concrete pavement maintenance device, including a movable base 1 with a water tank 2 fixed on the top surface, and multiple movable wheels 101 installed at the bottom of the movable base 1. It also includes two connecting seats 10, which are respectively set above two spray pipes 8. The top of the spray pipe 8 is fixed with a fixed seat 9, which cooperates with the connecting groove 1001 opened in the connecting seat 10. The connecting seat 10 is provided with two inserts 11, and the inserts 11 are inserted into the slots 901 opened on the top surface of the fixed seat 9. Two rotating shafts 1701 are fixedly connected to the two connecting seats 10 at their bottom ends. The bottom end of the spray pipe 8 is connected to multiple nozzles 801. The rotating shafts 1701 are used to drive the spray pipe 8 to rotate.

[0031] This embodiment provides a concrete pavement maintenance device. By inserting or separating the plug 11 from the slot 901, the locking and unlocking of the spray pipe 8 and the connecting seat 10 can be completed, realizing a detachable connection between the spray pipe 8 and the connecting seat 10. This facilitates subsequent maintenance or replacement of the spray pipe 8. The rotating shaft 1701 can drive the connecting seat 10 to rotate, and further drive the spray pipe 8 to rotate through the fixed seat 9, adjusting the coverage area of ​​the spray pipe 8, and realizing water spraying maintenance on pavements of different widths.

[0032] The movable base 1 is fixed to the fixed shell 19 on one side by two fixing blocks 102. The fixed shell 19 is provided with two meshing gears 17. The two gears 17 are fixed to the outer wall of the rotating shaft 1701. The top end of the rotating shaft 1701 is rotatably connected to the top plate of the fixed shell 19. The lower end of the rotating shaft 1701 passes through the bottom end of the fixed shell 19 and is rotatably connected to the fixed shell 19. The top surface of the fixed shell 19 is provided with a motor 18 whose output end is fixed to the top end of one of the rotating shafts 1701. The motor 18 drives the rotating shaft 1701 to rotate, which in turn drives the two gears 17 to rotate synchronously in opposite directions, so as to realize the synchronous reverse rotation of the two spray pipes 8.

[0033] The connecting seat 10 has two receiving grooves 1002 that communicate with the connecting groove 1001, and the receiving grooves 1002 are used to receive the insert 11. The cavity 1003 of the connecting seat 10 has two moving blocks 13. The top of the insert 11 is fixed with a smooth rod 1101 that is slidably connected to the connecting seat 10. The moving blocks 13 and the smooth rod 1101 are respectively fixed with hinge seats and hinged at both ends of the connecting rod 12. When the moving blocks 13 move in the opposite direction, the smooth rod 1101 will move synchronously through the connecting rod 12, and further drive the insert 11 to move vertically synchronously, so as to realize the insertion or separation of the insert 11 from the slot 901.

[0034] The cavity 1003 contains a bidirectional screw 14 that is rotatably installed and threadedly connected to two moving blocks 13. The connecting seat 10 has a knob 16 on its outside and the knob 16 is fixedly connected to one end of the bidirectional screw 14 via a connecting shaft 1601. Rotating the knob 16 drives the bidirectional screw 14 to rotate via the connecting shaft 1601, thereby driving the two moving blocks 13 to move in opposite directions.

[0035] The cavity 1003 is fixed with a guide rod 15 parallel to the bidirectional screw 14, and the guide rod 15 is slidably connected to the two moving blocks 13. The guide rod 15 guides the movement of the moving blocks 13, ensuring that the moving blocks 13 move along the guide rod 15 without rotating.

[0036] The mobile base 1 is equipped with a water pump 3 on its top surface. The water inlet of the water pump 3 is connected to the water tank 2 through the water inlet pipe 301, and the water outlet of the water pump 3 is connected to the three-way pipe 4 through the drain pipe 302. Both ends of the three-way pipe 4 are connected to connecting hoses 5. One end of the two spray pipes 8 is connected to a connecting pipe 6, and the connecting pipe 6 and the connecting hose 5 are connected by a connecting component 7. The connecting hose 5 and the connecting pipe 6 are detachably connected by the connecting component 7 to form a complete water supply path.

[0037] The connecting assembly 7 includes an externally threaded tube 701 fixed to the outer wall of one end of the connecting hose 5, and an end of the connecting tube 6 passing through an internally threaded sleeve 704 and fixed to a limiting ring 703. The internally threaded sleeve 704 is used to threadedly connect with the externally threaded tube 701. The internally threaded sleeve 704 is rotatably connected to the connecting tube 6. The connection between the connecting hose 5 and the connecting tube 6 is achieved by threading the internally threaded sleeve 704 and the externally threaded tube 701 together.

[0038] The connecting hose 5 is fixed with a connecting ring 702 at its end, and the outer wall of the connecting ring 702 is flared. The diameter of the end of the connecting ring 702 away from the connecting hose 5 is larger than the diameter of the end of the connecting ring 702 near the connecting hose 5. When the connecting hose 5 and the connecting pipe 6 are connected by the connecting assembly 7, the outer wall of the connecting ring 702 is covered with an elastic sealing layer of EPDM rubber to prevent leakage. When the connecting ring 702 is inserted into the connecting pipe 6, it abuts against the inner wall of the connecting pipe 6. The elastic sealing layer is compressed and deformed, forming an interference fit with the inner wall of the connecting pipe 6. The interference amount is 0.3mm to 0.5mm to ensure the water circuit is sealed.

[0039] It is understood that the spray pipe 8 in this utility model is detachable, which makes it convenient to remove it for maintenance and replacement. Secondly, the spray pipe 8 can be rotated to adjust the coverage area of ​​the spray pipe 8, so as to achieve watering and maintenance of roads of different widths.

[0040] A specific application of the operation process of this embodiment is as follows: The top of the water tank 2 is connected to a water injection pipe. Water is injected into the water tank 2 through the water injection pipe. Then, the drive motor 18 drives the two gears 17 to rotate. Furthermore, the two spray pipes 8 are rotated through the connecting seat 10 and the fixed seat 9 to adjust the coverage area of ​​the spray pipes 8, thereby adjusting the water coverage area when the nozzle 801 sprays water. This makes the device suitable for the maintenance of roads of different widths. The water pump 3 is started. The water in the water tank 2 enters the connecting hose 5 through the inlet pipe 301, the drain pipe 302, and the three-way pipe 4. Then, it enters the spray pipe 8 through the connecting component 7 and is finally evenly sprayed onto the road surface by the nozzle 801.

[0041] Rotate knob 16 to disengage insert 11 from slot 901, unlock spray pipe 8, rotate inner thread sleeve 704 to separate it from outer thread pipe 701, and then spray pipe 8 can be removed for maintenance or replacement.
