Description

Technical Field

[0001] This utility model relates to the field of waterproof construction equipment technology, and in particular to a multi-functional spraying device for bridge deck waterproofing layer construction. Background Technology

[0002] Bridges are critical infrastructure in transportation networks, and the durability and safety of their structures are of paramount importance. As the first line of defense protecting the main bridge structure and preventing steel reinforcement corrosion and concrete corrosion, the construction quality of the bridge deck waterproofing layer directly affects the bridge's service life. Currently, the common method for constructing bridge deck waterproofing layers is to spray liquid waterproofing material evenly onto the bridge surface.

[0003] Current spraying operations mostly utilize handheld spraying devices. However, the spray booms of these devices are typically of fixed length, making it difficult for operators to directly reach surfaces with a certain height, such as bridge railings or the sides of crash barriers. To complete the spraying, workers are forced to use ladders, scaffolding, and other auxiliary equipment for working at heights, which not only reduces construction efficiency but also poses significant safety hazards.

[0004] Furthermore, bridge structures are complex, with numerous tricky corners and angles, such as the junctions between the bridge deck and guardrails, and around drainage outlets. Traditional spraying equipment has a fixed nozzle angle, making it difficult to flexibly adjust to meet the spraying needs of these special locations. This often results in uneven spraying or the formation of missed areas and dead corners, affecting the overall protective effect of the waterproof layer and leaving potential hazards for future leaks.

[0005] Therefore, this utility model proposes a multi-functional spraying device for bridge deck waterproofing layer construction to overcome the shortcomings of the prior art. Utility Model Content

A rotating hand ring is rotatably connected to the outside of the limiting ring, and the inside of the rotating hand ring is threadedly connected to the outside of the movable frame. The nozzle is rotatably connected to the end of the movable frame away from the handheld frame. Both the driving gear and the driven wheel are rotatably mounted on the front end of the movable frame, and the driving gear meshes with the driven wheel. One end of the connecting rod is fixedly connected to the driven wheel, and the other end is fixedly connected to the nozzle.

[0009] Preferably, in order to achieve stable rotational engagement, a groove is provided on one side of the limiting ring, and a protrusion is fixedly connected to the corresponding side of the rotating wristband. The protrusion is rotatably accommodated inside the groove. This engaging structure ensures the axial stability of the rotating wristband during rotation.

[0010] Preferably, in order to facilitate stable operation by the operator over a long period of time, the outer side of the handheld frame is fixedly connected with an ergonomic handle.

[0011] Preferably, the handheld frame, the limiting ring, the movable frame, the rotating hand ring, and the handle together constitute a telescopic assembly for adjusting the working distance.

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0022] Example: Please refer to Figures 1 to 4This utility model provides a multi-functional spraying device for bridge deck waterproofing construction, which aims to solve the problems of fixed length and spraying angle of existing spraying devices, which lead to inconvenience, incomplete coverage and safety hazards in hard-to-reach areas such as high places or corners.

[0023] like Figure 1 , Figure 3 and Figure 4 As shown, the multi-functional spraying device for bridge deck waterproofing construction includes a handheld frame 101, a handle 105 fixedly connected to the outer side of the handheld frame 101, a movable frame 103 slidably connected to the inside of the handheld frame 101, a limit ring 102 fixedly connected to one end of the handheld frame 101, the movable frame 103 slidingly passing through the limit ring 102, and a rotating hand ring 104 rotatably connected to the outer side of the limit ring 102. The inner side of the rotating hand ring 104 is threadedly connected to the outer side of the movable frame 103. (Refer to...) Figure 3 A groove is provided on one side of the limiting ring 102, and a protrusion is fixedly connected to one side of the rotating hand ring 104. The protrusion is rotatably accommodated inside the groove. The hand holder 101, the limiting ring 102, the movable frame 103, the rotating hand ring 104, and the handle 105 together constitute the telescopic assembly 1; Figure 1 and Figure 2 As shown, the nozzle 204 is rotatably connected to the end of the movable frame 103 away from the handheld frame 101. The driving gear 201 and the driven wheel 202 are both rotatably mounted on the front end of the movable frame 103, and the driving gear 201 and the driven wheel 202 are meshed together. One end of the connecting rod 203 is fixedly connected to the driven wheel 202, and the other end is fixedly connected to the nozzle 204. The driving gear 201, the driven wheel 202, the connecting rod 203 and the nozzle 204 together constitute the adjustment assembly 2.

[0024] To solve the above-mentioned technical problems, the core of the technical solution of this embodiment lies in the fact that the telescopic component 1 and the adjustment component 2 of the multi-functional spraying device for bridge deck waterproofing layer construction form a specific structural cooperation and connection relationship.

[0025] Please refer to the following carefully. Figure 1 , Figure 3 and Figure 4The telescopic component 1 is described in detail below: The handheld frame 101 forms the main body for the operator to hold, and a movable frame 103 is slidably connected inside it. One end of the handheld frame 101 is fixedly connected to a limiting ring 102. The movable frame 103 slides through the inside of the limiting ring 102. The limiting ring 102 guides the linear movement of the movable frame 103. The core of realizing the telescopic function lies in the rotating hand ring 104. The rotating hand ring 104 is rotatably connected to the outside of the limiting ring 102, and the inside of the rotating hand ring 104 forms a threaded connection with the outside of the movable frame 103. This threaded transmission structure accurately converts the rotational movement of the rotating hand ring 104 into the axial linear movement of the movable frame 103, thereby realizing stable and controllable extension or retraction. To further stabilize the rotating connection, a groove is provided on one side of the limiting ring 102, and a protrusion is fixedly connected to one side of the rotating hand ring 104. The protrusion is rotatably accommodated inside the groove.

[0026] At the same time, please refer to Figure 1 and Figure 2 The adjustment component 2 is described in detail below: The driving gear 201 and the driven wheel 202 are both rotatably mounted on the front end of the movable frame 103. The driving gear 201 and the driven wheel 202 are meshed and connected. The nozzle 204 is rotatably connected to the end of the movable frame 103 away from the handheld frame 101. The connecting rod 203 establishes a connection between the transmission and actuation components. One end of the connecting rod 203 is fixedly connected to the driven wheel 202, and the other end is fixedly connected to the nozzle 204. This gear and connecting rod mechanism ensures that when the driving gear 201 is rotated, the driven wheel 202 rotates accordingly, and drives the connecting rod 203 to swing, thereby pushing or pulling the nozzle 204 to rotate around its pivot point, thus changing the relative angle of the nozzle 204.

[0027] Based on the above embodiments, the present invention may further include the following preferred technical solutions: As a preferred embodiment, for ease of handling by the operator, please refer to... Figure 1 and Figure 3 A handle 105 is fixedly connected to the outside of the handheld bracket 101.

[0028] As another preferred embodiment, to ensure the stability of the rotating connection, please refer to... Figure 3 A groove is provided on one side of the limiting ring 102, and a protrusion is fixedly connected to one side of the rotating hand ring 104. The protrusion is rotatably accommodated inside the groove.

[0029] As another preferred embodiment, in order to form a complete fluid spraying path, please refer to... Figure 1 The device also includes a liquid extractor 4 and a hose. The output end of the liquid extractor 4 is connected to the input end of the hose, and the output end of the hose is connected to the nozzle 204.

[0030] As a further limitation of the aforementioned embodiment, in order to cooperate with the telescopic movement of the movable frame 103, the outer periphery of the hose is fixedly connected to the movable frame 103.

[0031] As another preferred embodiment, for the purpose of on-site material preparation and pumping, please refer to... Figure 1 The device also includes a stirrer 3, and the suction pipe of the pump 4 extends into the container containing the stirrer 3.

[0032] The working principle of this multi-functional spraying device for bridge deck waterproofing layer construction is as follows: When spraying, a bucket containing waterproof material is placed on the ground of the work area. The agitator 3 is located inside the bucket to mix the material. The mixed material is then extracted from the bucket through the suction pipe of the liquid extractor 4 and transported to the spray head 204 through a hose. The operator operates the spray head by holding the handle 105 fixed to the outside of the handheld frame 101.

[0033] When spraying is required at a height, the worker twists the rotating hand ring 104. Since the inner side of the rotating hand ring 104 is threadedly connected to the outer side of the movable frame 103, the rotational motion of the rotating hand ring 104 is converted into the linear motion of the movable frame 103 through the threaded transmission. Under the guidance and restriction of the limiting ring 102, the movable frame 103 extends or retracts smoothly inside the hand-held frame 101, thereby changing the working distance of the spray nozzle 204, allowing the worker to complete the high-altitude spraying work while standing on the ground.

[0034] When it is necessary to spray a corner with a tricky angle, the worker turns the drive gear 201, which drives the driven wheel 202 to rotate through meshing transmission. The connecting rod 203, which is fixedly connected to the outside of the driven wheel 202, transmits the force to the spray head 204, which is fixedly connected to it, thereby changing the relative angle of the spray head 204 and completing the full spraying of the special position.

[0035] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
