Description

Technical Field

[0001] This utility model relates to the field of road construction technology, and in particular to a construction device for a waterproof bonding layer on bridge deck. Background Technology

[0002] During the construction of asphalt pavement, in order to improve the waterproof performance of the pavement, it is inevitable to spray a rubber asphalt waterproof bonding layer on the pavement. At present, the spraying of the waterproof bonding layer is mostly carried out by a sprayer truck. The existing asphalt sprayer truck mainly consists of a tank and a spraying device installed on the vehicle body. The waterproof asphalt coating in the tank is sprayed onto the pavement through the spraying device to form a waterproof bonding layer.

[0003] Existing spraying devices are mostly fixed and mounted on the vehicle body, with internal nozzles pointing vertically downwards to spray the coating onto the road surface in a fan shape. However, due to uneven road surfaces, especially on uphill sections, the distance between the nozzles and the road surface changes when the vehicle body tilts, resulting in gaps or overlaps between the coatings sprayed by adjacent nozzles, leading to uneven spraying. Therefore, we propose a bridge deck waterproof adhesive layer construction device to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to solve the problem in the existing technology that the distance between the nozzle and the road surface changes with the tilt of the vehicle during the spraying process, resulting in uneven spraying. Therefore, this invention proposes a bridge deck waterproof bonding layer construction device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A bridge deck waterproof bonding layer construction device includes a sprayer truck body, a tank body is provided on the sprayer truck body, and a spraying device connected to the tank body is provided at the rear end of the sprayer truck body. The spraying device includes two fixed cylinders installed on the sprayer truck body. Two guide rods are concentrically arranged in each of the two fixed cylinders. The guide rods pass through the fixed cylinders and are slidably connected to the fixed cylinders. A fixing block is provided on the section of the guide rod inside the fixed cylinder. A spring is provided between the fixing block and the upper end of the fixed cylinder.

[0007] The lower ends of both guide rods are equipped with auxiliary wheels, and a spray plate is fixed between the two guide rods. The spray plate is equipped with multiple nozzles that are connected to the tank through hoses.

[0008] Preferably, the rear end of the sprayer vehicle body is fixed with two mounting slots, each of which is equipped with a lead screw. One end of the lead screw is equipped with a servo motor, and a connecting block is threaded onto the lead screw. The fixed cylinder is mounted on the connecting block. The distance between the spray plate and the road surface can be adjusted by the operation of the servo motor. After the construction is completed, the auxiliary wheel can be driven away from the road surface, improving the safety of the sprayer vehicle body during operation.

[0009] Preferably, the connecting block is inserted into the mounting groove and slidably connected to the inner wall of the mounting groove, and the two ends of the connecting block are directly provided with bellows covers at the upper and lower ends of the mounting groove, so as to reduce the entry of impurities into the interior of the mounting groove.

[0010] Preferably, the lower end of the guide rod is fixed with a mounting bracket, the auxiliary wheel is set on the mounting bracket, and the auxiliary wheel is located on the side of the spray plate close to the center of the main body of the sprayer vehicle. Setting the auxiliary wheel at the front end of the spray plate avoids the waterproof adhesive layer from being squeezed by the auxiliary wheel after spraying.

[0011] Preferably, the spring is sleeved on the guide rod. By sleeved on the guide rod, the stability of the spring when compressed is improved.

[0012] Preferably, the tank is equipped with a stirring mechanism and a heating mechanism inside, and a paint pump is installed on the tank to deliver the asphalt paint to the nozzle. The stirring mechanism and the heating mechanism are existing structures, which respectively stir and heat the asphalt waterproof paint to prevent it from solidifying.

[0013] The beneficial effects of this utility model are as follows:

[0014] Compared with the prior art, this utility model adds an auxiliary wheel to the spraying device, and the spraying plate is fixed behind the auxiliary wheel. During the construction process, the auxiliary wheel is kept in contact with the road surface. When the vehicle is going uphill, the auxiliary wheel is squeezed and the spring is pushed to deform, thereby maintaining the distance between the nozzle and the road surface and reducing the phenomenon of uneven spraying.

[0019] 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. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present utility model or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0020] Reference Figure 1-3 A bridge deck waterproof bonding layer construction device includes a sprayer truck body 1, a tank body is provided on the sprayer truck body 1, and a spraying device 2 connected to the tank body is provided at the rear end of the sprayer truck body 1. The tank body is provided with a stirring mechanism and a heating mechanism, and a paint pump is provided on the tank body. The paint pump delivers asphalt paint to the nozzle 281. The stirring mechanism and the heating mechanism are existing structures, which respectively stir and heat the asphalt waterproof paint to prevent it from solidifying. This application only improves the structure of the spraying device 2 on the sprayer truck body 1.

[0021] The spraying device 2 includes two fixed cylinders 25 installed on the main body 1 of the sprayer vehicle. Two guide rods 26 are concentrically arranged in each of the two fixed cylinders 25. The guide rods 26 pass through the fixed cylinders 25 and are slidably connected to the fixed cylinders 25. A fixing block 261 is provided on the section of the guide rod 26 inside the fixed cylinder 25. A spring 262 is provided between the fixing block 261 and the upper end of the fixed cylinder 25. The spring 262 is sleeved on the guide rod 26. By sleeved on the guide rod 26, the stability of the spring 262 when it is squeezed is improved.

[0022] Auxiliary wheels 27 are installed at the lower ends of both guide rods 26. A mounting bracket is fixed at the lower end of the guide rods 26. The auxiliary wheels 27 are set on the mounting bracket and are located on the side of the spray plate 28 close to the center of the main body 1 of the sprayer. The auxiliary wheels 27 are set at the front end of the spray plate 28 to avoid the waterproof adhesive layer being squeezed after spraying.

[0023] Meanwhile, a spray plate 28 is fixed between the two guide rods 26, and multiple nozzles 281 connected to the tank body via hoses 282 are provided on the spray plate 28.

[0024] Furthermore, the fixed cylinder 25 can be directly installed on the main body 1 of the sprinkler truck. However, this method requires adjusting the height of the spray plate 28 during installation. Additionally, when the auxiliary wheel 27 contacts the road surface, the spring 262 must be under compression, placing high demands on the installation process. Therefore, our proposed improvement involves fixing two mounting slots 21 at the rear end of the main body 1 of the sprinkler truck. Each mounting slot 21 is equipped with a lead screw 22, one end of which is fitted with a servo motor 23. A connecting block 24 is threaded onto the lead screw 22. The connecting block 24 is inserted into the mounting slot 21 and slidably connected to the inner wall of the mounting slot 21. Bellows covers are directly installed at both ends of the connecting block 24 and the upper and lower ends of the mounting slot 21, reducing the entry of impurities into the mounting slot 21. By installing the fixed cylinder 25 on the connecting block 24, the distance between the spray plate 28 and the road surface can be adjusted via the operation of the servo motor 23. After construction, the auxiliary wheel 27 can be moved away from the road surface, improving the safety of the main body 1 of the sprinkler truck during operation.

[0025] In this embodiment, when the adhesive layer is sprayed, the servo motor 23 drives the lead screw 22 to rotate, the lead screw 22 drives the fixed cylinder 25 to move downward, and then drives the spray plate 28 and the auxiliary wheel 27 to move downward.

[0026] When the auxiliary wheel 27 contacts the road surface, the fixed cylinder 25 continues to descend a certain distance. At this time, the fixed block 261 compresses the spring 262, and the reaction force of the spring 262 pushes the auxiliary wheel 27 to always be in contact with the road surface. Thus, during the movement of the main body 1 of the sprayer, when the road surface is uneven or on an uphill section, the distance between the nozzle 281 and the road surface can remain unchanged, improving the uniformity of the waterproof adhesive layer spraying.
