Description

Technical Field

[0001] The utility model belongs to the technical field of road surface maintenance equipment, and particularly relates to a road surface spray maintenance device. Background Art

[0002] Pavement maintenance refers to regular maintenance and repair measures to ensure the normal use of roads, as well as the prevention and repair of catastrophic damage, so as to improve the quality of pavement. Among them, pavement spraying measures are a type of pavement maintenance. Whether it is after the paving of cement concrete pavement, the paving of asphalt road, or during daily maintenance, it is necessary to spray curing agent or clean water regularly. For example, the Chinese utility model patent with application number CN202320432491.1 discloses a frame device for connecting a sprinkler truck, and also includes a swing device for meshing and swinging installed on one side of the frame device. Two spray devices for spraying pavement maintenance are symmetrically installed on both sides of the swing device. The swing device includes a passive gear, a fixed frame is installed on one side of the passive gear, and two avoidance grooves are symmetrically arranged on both sides of the fixed frame. The spray device includes a water pipe, and a number of nozzles are evenly installed at the bottom of the water pipe. A pipe joint is arranged on the water pipe, and an electric control valve is installed on the pipe joint.

[0003] Although the above scheme facilitates the swing to one side of the sprinkler truck for spraying through the setting of left and right swinging multi-head spraying, thus ensuring the comprehensiveness of the spraying, the swinging rotation is too large and the load is too large when only driven by a single-point motor gear during the swinging, and the swing amplitude is slow, which is not conducive to improving the efficiency of the spraying work. At the same time, the swinging device is not easy to store and will take up a large placement space. For wider roads, the adaptability, maneuverability and flexibility of the single-arm swinging device are slightly insufficient.

[0004] Therefore, a road surface spraying maintenance device is needed. Utility Model Content

[0005] The purpose of the utility model is to provide a road surface spray maintenance device, thereby overcoming the defects of the traditional single swing arm spray device, such as low working efficiency and inflexible space occupation. The specific technical solution is as follows:

[0006] A road surface spray maintenance device comprises a pump body, a support rod is arranged at one end of the pump body, an X-shaped spray rod is rotatably mounted on the bottom of one end of the support rod, a drive motor is mounted on the top of one end of the support rod, a spray sub-rod is slidably mounted on the X-shaped spray rod, a first spray head is arranged at intervals at the bottom of the X-shaped spray rod, and a second spray head is arranged at intervals at the bottom of the spray sub-rod.

[0007] Preferably, a secondary telescopic rod is provided at the front end of the support rod, and the secondary telescopic rod is slidably installed inside the support rod.

[0008] Preferably, a fixing plate is provided on the top of the X-shaped spray rod, and the rotating shaft of the driving motor is rotatably connected to the fixing plate.

[0009] Preferably, a receiving groove is provided on the X-shaped spray rod, and the spray sub-rod is slidably installed in the receiving groove.

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Example

[0025] A road surface spraying maintenance device, such as Figures 1 to 5 As shown, it includes a pump body 1, which is used to pump the curing agent or cleaning water to the first spray head 6 or the second spray head 7 through a hose, and the hose can be arranged inside the support rod 2, the X-shaped spray rod 3 and the spray sub-rod 5. A support rod 2 is arranged at one end of the pump body 1, and an X-shaped spray rod 3 is rotatably installed at the bottom of one end of the support rod 2. A driving motor 4 is installed at the top of one end of the support rod 2, and a spray sub-rod 5 is slidably installed on the X-shaped spray rod 3. The first spray head 6 is arranged at intervals at the bottom of the X-shaped spray rod 3, and the second spray head 7 is arranged at intervals at the bottom of the spray sub-rod 5.

[0026] The front end of the support rod 2 is provided with a secondary telescopic rod 8, which is slidably mounted inside the support rod 2. When in use, the secondary telescopic rod 8 is extended to allow the X-shaped spray rod 3 to perform spray maintenance work on the road surface. When not in use, the secondary telescopic rod 8 can be retracted into the support rod 2, which is beneficial to saving space occupied by the equipment. At the same time, the extension length of the secondary telescopic rod 8 can be adjusted according to the width of the road surface, which improves the flexibility and adaptability of the device.

[0027] A fixing plate 9 is arranged on the top of the X-shaped spray rod 3, and the rotating shaft of the driving motor 4 is rotatably connected to the fixing plate 9. Through the action of the driving motor 4, the X-shaped spray rod 3 can realize a rotary spraying operation. Compared with the traditional swinging spraying method, the rotary spraying method can not only be more uniform and comprehensive, but also improve the spraying efficiency, and the driving method is more flexible and labor-saving, avoiding the shortcomings of the traditional single swing arm type of single-point force and overload.

[0028] The X-shaped spray rod 3 is provided with a receiving groove 10, and the spray sub-rod 5 is slidably installed in the receiving groove 10. When a wider road surface needs to be sprayed, the spray sub-rod 5 is pulled out from the receiving groove 10 to adjust the spray width adaptively.

[0029] Furthermore, in order to ensure the stability of the rotation of the X-shaped spray rod 3, a plurality of buckle grooves 11 are spaced apart on the top of the spray sub-rod 5, and a plurality of buckle blocks 12 are spaced apart on the inner top wall of the X-shaped spray rod 3. When in use, the spray sub-rod 5 is stretched so that the buckle blocks 12 and the buckle grooves 11 are engaged with each other to maintain stability and prevent the spray sub-rod 5 from shaking when rotating.

[0030] like Figures 4 to 5 As shown, a plurality of buckle blocks 12 are elastically mounted on the inner top wall of the X-shaped spray pipe, and a compression spring 13 is connected to the top of the plurality of buckle blocks 12. When the spray sub-rod 5 and the X-shaped spray rod 3 are in sliding contact, the buckle blocks 12 will be correspondingly buckled into the buckle groove 11. At the same time, arc-shaped contact surfaces 14 are provided on the bottom contact surfaces of the plurality of buckle blocks 12 to improve the smoothness of the buckle fitting, and the operation of sliding, retracting or retracting the spray sub-rod 5 is also smoother.

[0031] In summary, by setting up an X-shaped spray rod 3 driven by a driving motor 4, the X-shaped spray rod 3 can realize a rotary spraying operation. Compared with the traditional swinging spraying method, the rotary spraying method is not only more uniform and comprehensive, but also can improve the spraying efficiency, and the driving method is more flexible and labor-saving, avoiding the shortcomings of the traditional single swing arm type of single-point force and excessive load. For wider roads, the spray width can be adaptively adjusted by pulling the spray sub-rod 5 out of the storage groove 10.
