Description

Technical Field

[0001] This utility model relates to the field of spraying equipment technology, specifically to a waterproof spraying robot for beam ends. Background Technology

[0002] The statements herein provide only background information related to this invention and do not necessarily constitute prior art.

[0003] Beam ends, especially the ends of cantilevered components that contact the outdoors, such as balcony beams, canopy beams, air conditioning slab beams, and exterior wall frame beams, are high-risk areas for moisture penetration. If waterproofing is neglected or fails, moisture can penetrate along the following paths: 1. Through cracks: Concrete develops tiny shrinkage cracks during hardening; beam ends, being areas of complex stress, are more prone to cracking, becoming channels for water. 2. Through material capillary pores: Concrete and masonry (such as bricks and aerated concrete blocks) are inherently porous materials, allowing water to be drawn into them through capillary action. 3. Through joint gaps: Construction joints exist between beams and infill walls, and between beams and slabs; these are weak points in waterproofing.

[0004] If the beam ends are not waterproofed, the intruding moisture will trigger a series of chain reactions, causing serious damage, such as threats to structural safety, impacts on building function and durability, and destruction of building aesthetics.

[0005] Currently, in building and bridge construction, waterproofing at beam ends mainly relies on manual spraying. Manual spraying suffers from problems such as high labor intensity and low efficiency.

[0006] To address these issues, this invention provides a waterproof spraying robot for beam ends. Utility Model Content

[0007] The main purpose of this invention is to provide a waterproof spraying robot for beam ends that can replace manual spraying and whose nozzles are easy to maintain and replace.

[0008] To achieve the above objectives, the technical solution of this utility model is as follows: a waterproof spraying robot for beam ends includes a mobile carrier, a mechanical arm is provided on the top of the mobile carrier, a nozzle for spraying waterproof coating onto the beam end is provided on the mechanical arm, a conveying pipe for supplying waterproof coating is provided on the mechanical arm, a spray pipe is connected to the inlet end of the nozzle, and the inlet end of the spray pipe can be axially inserted and connected to the outlet end of the conveying pipe. It also includes a locking component, which is triggered by axially inserting the feed end of the nozzle into the discharge end of the conveying pipe, thereby sealing and locking the feed end of the nozzle and the discharge end of the conveying pipe together.

[0009] Furthermore, the discharge end of the conveying pipe is provided with an insertion hole for the inlet end of the spray pipe to be inserted. The locking component includes a groove circumferentially formed around the inner periphery of the insertion hole. An elastic layer is provided at the groove opening to cover the groove opening. A pressure area is formed between the groove and the inner side of the elastic layer. A docking groove is circumferentially formed around the outer side of the inlet end of the spray pipe. By driving the inlet end of the spray pipe to be axially inserted into the discharge end of the conveying pipe, the pressure in the pressure area is increased, forcing the elastic layer to expand and deform to seal and dock with the docking groove.

[0010] Furthermore, the feed pipe has an axially formed plug groove with a connecting groove inside. A fixed plate is fixed in the plug groove, and a push rod parallel to the axial direction of the feed pipe is slidably inserted into the fixed plate. A piston that cooperates with the plug groove is provided at one end of the push rod near the groove. Both the pressure area and the plug groove contain pressure medium. An insert block that contacts and cooperates with the other end of the push rod is provided on the outer wall of the nozzle. The feed pipe outlet end has an axially formed slot for the insert block to be inserted and connected to the plug groove.

[0011] Furthermore, a spring is sleeved on the outside of the push rod, with the two ends of the spring connected to the wall of the fixed plate and the outer wall of the piston, respectively. When the insert block presses against the push rod, the push rod moves in the direction of the groove, and the spring is stretched and deformed.

[0012] Furthermore, the insert block has a locking hole on the side away from the nozzle, and a locking rod that engages with the locking hole is radially inserted into the outer wall of the feed pipe.

[0013] Furthermore, the mobile carrier is equipped with a material cylinder containing waterproof coating. A material pump is installed at the bottom outlet of the material cylinder. The output end of the material pump is connected to the inlet end of the spraying chamber on the robotic arm through a feeding pipe. The outlet end of the spraying chamber is connected to the inlet end of the feeding pipe.

[0014] The beneficial effects of this utility model are reflected in: This utility model relates to a waterproof spraying robot for beam ends, which replaces the manual spraying method for beam ends. It uses a mobile carrier in conjunction with a robotic arm to perform mobile waterproof spraying operations on beam ends, saving time and labor, and achieving high work efficiency. Furthermore, the spray nozzle can be quickly disassembled and assembled on the robotic arm before and after spraying, making it convenient to replace the spray nozzle or perform backwashing maintenance.

[0017] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. Obviously, the described embodiments are only a part of the embodiments of the utility model, and not all of them. Unless otherwise specified, the embodiments and features described in this application can be combined with each other. All other embodiments obtained by those skilled in the art based on the embodiments of the utility model without creative effort are within the scope of protection of the utility model.

[0018] Please combine Figures 1 to 4 .

[0019] A beam end waterproof spraying robot includes a mobile carrier 1, a robotic arm 2 on the top of the mobile carrier 1, a nozzle 5 for spraying waterproof coating onto the beam end on the robotic arm 2, a conveying pipe 4 for supplying waterproof coating on the robotic arm 2, a spray pipe 6 connected to the inlet end of the nozzle 5, and the inlet end of the spray pipe 6 can be axially inserted and connected to the outlet end of the conveying pipe 4. It also includes a locking component, which is triggered by axially inserting the feed end of the nozzle 6 into the discharge end of the conveying pipe 4 to seal and lock the feed end of the nozzle 6 and the discharge end of the conveying pipe 4.

[0020] In practice, before use, the nozzle 5's spray pipe 6 is axially inserted into the feed end of the conveying pipe 4, and with the use of the locking component, the input end of the spray pipe 6 and the output end of the conveying pipe 4 are mutually sealed and locked. Then, the robotic arm 2 is moved to the beam end by the mobile carrier 1. The robotic arm 2 adjusts the nozzle 5 to the position corresponding to the beam end, and uses the conveying pipe 4 to deliver waterproof coating to the spray pipe 6 and spray it out from the nozzle 5. With the assistance of the movement of the mobile carrier 1, the waterproof coating is sprayed on the beam end.

[0021] The advantage of this design is that it allows for mobile waterproof spraying of the beam end, and the spray nozzle 6 of the nozzle 5 can be quickly disassembled and assembled on the feed pipe 4 of the robotic arm 2 before and after spraying, making it convenient to replace or backwash the nozzle 5 for maintenance.

[0022] It should be noted that the mobile vehicle 1 can be a locomotive chassis with a drive unit (internal combustion engine or electric motor) and tires. The robotic arm 2 can adjust the spraying direction, position and angle of the spray nozzle 5. The mobile vehicle 1 and the robotic arm 2 are existing technologies, and this application will not elaborate on them further.

[0023] In one embodiment, the discharge end of the feed pipe 4 is provided with an insertion hole 7 for the feed end of the nozzle 6 to be inserted. The locking component includes a groove 8 circumferentially formed around the inner periphery of the insertion hole 7. An elastic layer 9 is provided at the opening of the groove 8 to cover the opening. A pressure area is formed between the groove 8 and the inner side of the elastic layer 9. A docking groove 10 is circumferentially formed around the outer side of the feed end of the nozzle 6. By driving the feed end of the nozzle 6 to be axially inserted into the discharge end of the feed pipe 4, the pressure in the pressure area is increased, forcing the elastic layer 9 to expand and deform to seal and dock with the docking groove 10.

[0024] Thus, when the feed end of the nozzle 6 is axially inserted into the discharge end of the conveying pipe 4 (the elastic layer 9 and the docking groove 10 are in corresponding positions), the pressure in the pressure area can be increased, forcing the elastic layer 9 to expand and deform to seal and squeeze with the docking groove 10, thereby achieving the sealing and fixing of the relative position of the feed end of the nozzle 6 in the discharge end of the conveying pipe 4.

[0025] In this embodiment, the elastic layer 9 can be a rubber layer. Initially, the rubber layer is in a non-expanded state, and the elastic layer 9 is located outside the docking groove 10 to avoid interfering with the axial movement of the nozzle 6 in the insertion hole 7. When the pressure in the pressure area increases, the elastic layer 9 expands and deforms to abut and snap into the docking groove 10, thereby achieving a sealed docking between the nozzle 6 and the feed pipe 4.

[0026] In one embodiment, the feed pipe 4 has an axially formed plug groove 11 that communicates with the groove 8. A fixed plate 13 is fixed in the plug groove 11. A push rod 14 parallel to the axial direction of the feed pipe 4 is slidably inserted on the fixed plate 13. A piston 12 that cooperates with the plug groove 11 is provided at one end of the push rod 14 near the groove 8. Both the pressure area and the plug groove 11 contain pressure medium. An insert block 15 that contacts and cooperates with the other end of the push rod 14 is provided on the outer wall of the nozzle 6. A slot 16 that allows the insert block 15 to be inserted and communicates with the plug groove 11 is axially formed at the discharge end of the feed pipe 4.

[0027] Thus, when the nozzle 6 is inserted into the socket 7, the insert block 15 will enter the slot 16, and then the insert block 15 will press the push rod 14, forcing the push rod 14 to drive the piston 12 to move in the plug groove 11 towards the groove 8, so as to squeeze the pressure medium in the pressure area, and force the elastic layer 9 to expand and deform so as to tightly connect with the docking groove 10.

[0028] In this embodiment, the pressure medium can be hydraulic oil with good fluidity.

[0029] In one embodiment, a spring is sleeved on the outside of the push rod 14, and the two ends of the spring are respectively connected to the wall of the fixed plate 13 and the outer wall of the piston 12. When the insert block 15 presses the push rod 14, the push rod 14 moves in the direction of the groove 8, and the spring is stretched and deformed.

[0030] Thus, when the push rod 14 drives the piston 12 to move in the direction of the groove 8 in the plug groove 11, the spring is stretched and deformed. The spring deformation can be used to release the spring force when the insert block 15 is disengaged from the push rod 14, causing the piston 12 to move back to the initial position, so that the elastic layer 9 returns to the initial non-expanded state.

[0031] In one embodiment, the insert 15 has a locking hole 18 on the side away from the nozzle 6, and a locking rod 17 that engages with the locking hole 18 is radially inserted into the outer wall of the feed pipe 4.

[0032] Thus, when the nozzle 6 is inserted into the feed pipe 4, the locking rod 17 is engaged in the locking hole 18, which further locks the relative position of the nozzle 6 in the feed pipe 4. At the same time, the elastic layer 9 can always maintain an expanded deformation state, so that the sealing state between the nozzle 6 and the feed pipe 4 remains stable.

[0033] In one embodiment, a material cylinder 19 containing waterproof coating is provided on the mobile carrier 1. A material pump 20 is installed at the bottom outlet of the material cylinder 19. The output end of the material pump 20 is connected to the inlet end of the spraying chamber 3 on the robotic arm 2 through the feeding pipe 21. The outlet end of the spraying chamber 3 is connected to the inlet end of the feeding pipe 4.

[0034] In this way, the material pump 20 can transport the material in the material cylinder 19 to the material conveying pipe of the robotic arm 2 through the material feeding pipe 21, and then transport it to the feeding end of the spraying chamber 3 through the material conveying pipe 4, the spraying pipe 6 and the nozzle 5 in sequence to spray the beam end.

[0035] In this embodiment, the material cylinder 19 has a stirring blade inside, and the outer wall of the material cylinder 19 has a material inlet for inputting the coating. A stirring motor is installed on the top of the material cylinder 19, and the output shaft of the stirring motor extends into the material cylinder 19 and connects to the stirring blade to stir and mix the coating in the material cylinder 19 before conveying.

[0036] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.

[0037] It should be noted that if the utility model embodiment involves directional indicators (such as up and down), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0038] Furthermore, the meaning of "and / or" throughout the text includes three parallel solutions. Taking "A and / or B" as an example, it includes solution A, solution B, or a solution that simultaneously satisfies A and B. Additionally, if the utility model embodiments involve descriptions of "first," "second," etc., these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of indicated technical features. Therefore, features defined with "first" or "second" can explicitly or implicitly include at least one of those features. Furthermore, "multiple" refers to two or more. Additionally, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by the utility model.
