Description

Technical Field

[0001] The utility model relates to the technical field of spraying, in particular to a novel spraying device for a waterproof layer of a waterproof asphalt concrete pavement. Background Art

[0002] Asphalt pavement refers to various types of pavement paved with road asphalt materials mixed into mineral materials. Asphalt binder improves the ability of paving aggregate to resist damage to the road surface caused by traffic and natural factors, making the road surface smooth, dust-free, impermeable and durable. In the process of asphalt pavement paving, it is necessary to spray a waterproof layer on the road surface, so non-curing sprayers are used.

[0003] The patent with the current announcement number CN211801930U discloses a non-curing sprayer, including a sprayer body, the bottom of which is connected to a bottom plate by bolts, and the bottom of the bottom plate is fixedly connected to four universal wheels distributed in a rectangular shape, a discharge port is arranged on one side of the top of the sprayer body, and a nozzle is fixedly connected to the top of the discharge port, a spray gun is fixedly connected to the top of the nozzle, and an electric push rod is connected to the top of the sprayer body by bolts, a pull rod is rotatably connected to the top of the electric push rod, and a fixed sleeve is welded to one end of the pull rod, and the spray gun is clamped inside the fixed sleeve. When the device is in use, the staff stands on one side of the control panel of the sprayer body and controls the spray direction of the spray gun through the pull rod, which is convenient for manipulating the sprayer body while spraying, making the spraying work more convenient, and the electric push rod can adjust the height of the spray gun, which increases the spraying area of ​​the spray gun. Although the above device solves the problem of adjusting the height of the spray gun, there are still other shortcomings.

[0004] When the above device is in use, after the worker completes spraying of an area, the sprayed area needs to be covered with asphalt waterproofing membrane. Therefore, the spray rod of the sprayer needs to be placed on the ground, which causes the worker to squat down to put down the spray rod and pick it up again when using it. Frequent squatting and standing up will increase the labor intensity of the worker, causing inconvenience. Utility Model Content

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] like Figures 1 to 5 As shown, a new type of spraying device for waterproofing asphalt concrete pavement waterproof layer includes a sprayer body 1 and a spray rod 2 connected to one side of the sprayer body 1, the outer side of the spray rod 2 is connected to a support assembly 3, the support assembly 3 includes two fixing rings 301, the two fixing rings 301 are fixedly connected to the outer side of the spray rod 2, the bottom of the fixing ring 301 away from the spray head of the spray rod 2 is fixedly connected to a fixing rod 302, the bottom of the fixing ring 301 close to the spray head of the spray rod 2 is rotatably connected to a rotating rod 303, the outer wall of the rotating rod 303 is connected to a protective assembly 4, and the rotating rod 303 is connected to a limiting assembly 5.

[0022] like Figure 1 As shown, the new spraying device for waterproofing asphalt concrete pavement waterproofing layer in the utility model is similar to the existing non-solidifying spraying machine structure, such as the non-solidifying spraying machine disclosed in the patent with announcement number CN211801930U. The main improvement of the utility model is to facilitate the removal of the spraying rod of the spraying machine, such as Figures 1 to 5 As shown, when the new spraying device for waterproofing asphalt concrete pavement waterproof layer in the utility model is in use, when the user needs to put the spray rod 2 on the ground during the use of the spray rod 2, the limit assembly 5 can be opened, so that the rotating rod 303 can be rotated and opened by its own gravity, and then, it is only necessary to support the bottom of the rotating rod 303 with the ground, and at the same time, with the cooperation of the fixed rod 302, the spray rod 2 is supported on the ground in an inclined state. This arrangement allows the staff to put down the spray rod 2 without squatting and standing up. They only need to rotate the rotating rod 303 to open the spray rod 2, so that the spray rod 2 can be supported, which is convenient for taking, reducing the labor intensity of the workers.

[0023] By arranging two fixing rings 301 on the outer wall of the spray rod 2, and arranging a rotating rod 303 and a fixed rod 302 on the outer sides of the fixing ring 301 respectively, the rotating rod 303 can support the spray rod 2 in an inclined state. With this arrangement, when the workers put down the spray rod 2, they do not need to squat or stand up. They only need to rotate and open the rotating rod 303, and the spray rod 2 can be supported, which makes it convenient for the workers to take it next time, thereby reducing the labor intensity of the workers.

[0024] like Figure 2 and Figure 3 As shown, the protection component 4 includes a connecting rod 401 arranged obliquely, the connecting rod 401 is fixedly connected to the outer wall of the rotating rod 303, and a protective shell 402 is fixed at one end of the connecting rod 401 away from the rotating rod 303, and the protective shell 402 is located outside the nozzle of the spray rod 2.

[0025] Specifically, when the rotating rod 303 is rotated and opened, the connecting rod 401 will drive the protective shell 402 to rotate and open, thereby protecting the nozzle of the spray rod 2. This arrangement can facilitate the protection of the nozzle and prevent people from accidentally touching the nozzle after it is supported as a whole, thereby causing paint to adhere.

[0026] like Figure 3 and Figure 5 As shown, the limiting component 5 includes a strap 501 and a Velcro 502 . The strap 501 is fixedly connected to one side of the rotating rod 303 . The outer wall of the other side of the rotating rod 303 is fixedly connected with the Velcro 502 . The Velcro 502 is bonded to the strap 501 .

[0027] Specifically, when the rotating rod 303 needs to be opened, it is only necessary to tear off the strap 501 and the Velcro 502 to separate the rotating rod 303 from the outer wall of the spray rod 2. When the rotating rod 303 needs to be fixed, it is only necessary to turn the rotating rod 303 back and use the strap 501 to bond it through the Velcro 502.

[0028] like Figure 3 , Figure 4 and Figure 5 As shown, the cross section of the rotating rod 303 is a semicircular arrangement. In this arrangement, the cross section of the rotating rod 303 is larger, and can be well supported by the bottom surface. The bottom of the rotating rod 303 can also be tilted, and in this arrangement, it can be more stably supported by the ground.

[0029] like Figure 4 As shown, the bottom of the fixing rod 302 is fixedly connected with a bottom plate 7. The bottom plate 7 increases the contact area between the fixing rod 302 and the ground, making the support more stable.

[0030] like Figure 3As shown, two symmetrically arranged integral rods 6 are fixedly connected between the two fixing rings 301, and the two integral rods 6 are symmetrically arranged. Such an arrangement allows the two fixing rings 301 to form a whole, and the fixing rings 301 here can be welded to the spray rod 2, and can also be detachably connected, such as by magnetic attraction or a clamp.

[0031] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
