Abstract
Description
Technical Field
[0001] This utility model relates to the field of residential wall renovation technology, and in particular to a spraying operation device for the renovation of the exterior facade of old residential walls. Background Technology
[0002] As residential buildings age, many structural elements reach the end of their service life and require maintenance, such as the protective coatings on the exterior facades. In particular, waterproof paint ages and its waterproofing performance decreases over time, thus reducing the overall waterproofing of the exterior walls.
[0003] Therefore, during the renovation of old residential buildings, it is necessary to remove the aging paint layer on the exterior facade of the building, clean the walls, and then repaint them to improve the aesthetics and increase the waterproof performance of the exterior walls.
[0004] The current spraying method involves operators being secured by safety ropes and spraying paint downwards along the wall. The drawback of this method is that, due to the large surface area of the building's exterior walls, several operators are needed to spray a certain width of paint along the height before re-secured and switching spraying positions. Therefore, the overall workload and tasks are very large.
[0005] For older residential buildings, especially high-rise buildings, the exterior facades are very large, resulting in a significant workload. Without an efficient work method, the renovation of older residential buildings is very inefficient.
[0006] Furthermore, this method of working at height by manually pulling the equipment is not only highly dangerous but also inefficient. Especially when the wind suddenly picks up, the operators are swayed by the wind at high altitudes, which is extremely dangerous.
[0007] The exterior of the walls is mostly a flat and unobstructed vertical plane structure, which provides the basic conditions for mechanized spraying operations. Therefore, if the operation can be carried out in a way that does not require manual high-altitude work, it will not only be more efficient, but also greatly reduce the safety risks of manual operations. Utility Model Content
[0008] Based on the above background, the purpose of this utility model is to provide a spraying device for the renovation of the exterior facade of old residential buildings.
[0009] To achieve the above objectives, the present invention adopts the following technical solution:
[0010] A spraying device for renovating the exterior facade of an old residential building includes a spraying mechanism suspended from the top of the building; the spraying mechanism includes a sliding support that slides against the exterior facade of the wall; the sliding support is lowered by a rope-releasing structure.
[0011] A long spray pipe is slidably connected inside the lower sliding bracket, and several spray nozzles facing the wall are connected to the long spray pipe.
[0012] It also includes a drive structure that propels the long spray pipe in reciprocating motion;
[0013] The spraying mechanism also includes a lower guide rope structure to prevent the lower sliding support from swaying;
[0014] The lower rope structure includes a lower rope that is suspended from the top of the building, with the bottom of the lower rope tensioned and anchored to the ground; a guide pulley structure that guides the lower rope is fixedly assembled on the lower sliding support.
[0015] Preferably, the lower sliding support is frame-shaped;
[0016] The two ends of the downward sliding bracket are respectively rotatably connected to downward sliding rollers that roll against the exterior wall surface.
[0017] Preferably, both ends of the long spray pipe are fixedly connected to slide rail rods, and both ends of the lower sliding bracket are fixedly connected to guide sleeves that slidably connect to the slide rail rods;
[0018] The drive structure includes a push link hinged to a slide rail on one side, and a motor fixedly installed in the lower sliding bracket. The output shaft of the motor is fixedly connected to a turntable, and the push link is hinged to the eccentric position of the turntable.
[0019] Preferably, the top of the spray pipe is connected to a pump feed pipe, which is connected to a pump feed pump via a hose. The pump feed pump is used to pump the paint into the long spray pipe.
[0020] The top of the lower sliding support is provided with a long sliding port that cooperates with the pump feed pipe, and the pump feed pipe passes through the long sliding port.
[0021] Preferably, the unwinding structure includes unwinding motors spaced apart on both sides, and a winding wheel is fixedly connected to the output shaft of the unwinding motor;
[0022] A pull rope is wound on the rope reel, and the bottom of the pull rope is attached to the top of the lower sliding bracket.
[0023] Preferably, the bottom of the unwinding motor is fixedly connected to a motor base, and the motor base is fixedly installed on the guardrail on the roof of the building.
[0024] Preferably, the lower guide rope structure includes a pair of lower guide ropes spaced apart;
[0025] The outer ends of the lower sliding support are respectively fixedly installed with pulley structures that cooperate with the lower sliding rope;
[0026] The lower guide rope is positioned on the outside of the lower sliding support;
[0027] The top of the lower guide rope is fitted with a guide rope fixing bracket, which is fixedly installed on the guardrail on the roof of the building.
[0028] Preferably, the guide roller structure includes a guide roller bracket fixedly connected to the lower sliding bracket;
[0029] A pair of guide rollers are rotatably connected inside the guide roller bracket. The guide rollers have annular guide grooves on their outlines. The lower guide rope is limited between the annular guide grooves of the pair of guide rollers.
[0030] Preferably, the guide roller bracket includes a U-shaped bracket portion welded and fixed to the lower sliding bracket, a roller bracket portion welded to the U-shaped bracket portion, and the guide roller is rotatably connected to the roller bracket portion.

[0032] 1.

Therefore, compared with traditional manual high-altitude operations, it is not only more efficient but also much safer.
[0033] 2. During operation, driven by a motor, a rotating turntable continuously pushes a long spray nozzle, via a connecting rod, to swing left and right in a linear fashion. The paint sprayed from the nozzle covers the wall in this oscillating motion, improving spraying quality and ensuring the uniformity of the paint coverage, including thickness. For example, when spraying waterproof coatings, this method guarantees the quality of the waterproofing work. This simulates the continuous oscillation of the spray gun during manual spraying, ensuring the paint is fully and evenly applied to the wall.
[0034] 3. The guide pulley and lower rope structure design ensures that the guide pulley rolls relative to the lower rope during the entire descent process, while the lower rope is confined within the guide pulley. Therefore, the limiting effect between the guide pulley and the lower rope achieves an anti-detachment effect. Even under wind conditions, the entire device, thanks to the guide pulley and lower rope structure design, offers high stability and is not easily loosened or blown away by the wind.

[0046] Example 1
[0047] like Figure 1-6 As shown, a spraying device for the renovation of the exterior facade of an old residential building includes a spraying mechanism 1 suspended from the roof of the building; specifically, it is suspended from the railing 4 on the roof of the building. The railing 4 serves as the anchor point. In actual work, most residential buildings in the community have railings 4 on their roofs as a protective structure. However, for building structures without railings 4, it is necessary to manually build temporary supports during the actual work process, such as using scaffolding to build a temporary anchor support for the spraying mechanism 1 (in engineering construction, building simple scaffolding as the anchor point is a very common construction method in the existing technology).
[0048] In reality, most residential buildings, especially high-rise buildings, have roof railings (roof railings are a requirement of building construction standards).
[0049] The spraying mechanism 1 employs mechanized and automated operation, sliding down the exterior wall from top to bottom, completing the spraying operation on the entire wall in one go during the sliding process. Therefore, compared with traditional manual high-altitude operations, it is not only more efficient but also much safer.
[0050] Specifically, the spraying mechanism 1 includes a sliding support 11 (the length of which corresponds to the width of the exterior wall surface, and is formed by welding a lightweight aluminum alloy steel frame, with a frame-like structure) that slides against the exterior wall surface; the sliding support 11 is lowered by a rope release structure 3.
[0051] During the lowering process, the lowering support 11 is lowered by rolling the lowering rollers 12 that are rotatably connected to both ends of the lowering support 11 on the outer facade of the wall.
[0052] Specifically, following the same principle and method as existing rope-based lowering, the rope-releasing structure 3 includes a winding motor 32 spaced apart on both sides, with a winding wheel 321 fixedly connected to the output shaft of the winding motor 32; a rope 33 is wound on the winding wheel 321, and the bottom of the rope 33 is attached to the top of the lower sliding bracket 11.
[0053] That is, the pull ropes 33 on the left and right sides are attached to the top of the lower sliding bracket 11 on the left and right sides to ensure balance. The attachment method is as follows: according to the existing method, a safety buckle (not shown in the figure) is fixed to the bottom of the pull rope 33, and correspondingly, a hanging ring (not shown in the figure) is fixedly connected to the top of the lower sliding bracket 11, and the safety buckle is locked on the hanging ring.
[0054] Since the rope-laying structure 3 is anchored to the roof railing 4, the bottom of the unwinding motor 323 is fixedly connected to a motor base 31, which is then fixedly installed on the railing 4 on the roof of the building.
[0055] The specific method by which the motor base 31 is anchored to the guardrail 4 is a conventional anchoring structure disclosed in the prior art. For example, a pair of mounting plates are welded to the motor base 31, and a pair of tensioning screws are installed on the mounting plates. After the motor base 31 is passed through the guardrail 4, the tensioning plate is put on between the screws. The tensioning plate and the mounting plate lock the guardrail 4 in place, and then the nuts are tightened. The entire device is anchored in this way.
[0056] In actual operation, in order to increase the stability of the anchoring, the motor can be further reinforced by reinforcing the structure, such as welding a diagonal support rod on the motor base 31, which is supported on the guardrail 4.
[0057] During operation, as the motor base 31 gradually drives the winding pulley 321 to unwind, the entire device slides smoothly down the wall. To ensure the stability of the descent and avoid the reverse impact force generated during spraying under wind conditions, which could cause the entire device to shake, the following descent rope structure is used to increase stability. The descent rope structure is equivalent to a cableway, providing protection while increasing stability.
[0058] Example 2
[0059] like Figure 1-6 As shown, in this embodiment, based on the structure of Embodiment 1, a long spray pipe 13 is slidably connected inside the aforementioned sliding bracket 11. Several nozzles 15 facing the wall are connected to the long spray pipe 13. The nozzles 15 are conventional paint sprayers disclosed in the prior art. According to existing methods, the nozzles 15 are detachably installed on the nozzle 15 interface of the long spray pipe 13, for the purpose of spraying different types of coatings during construction, including spraying subsequent insulation coatings.
[0060] During the spraying process, the nozzle 15 sprays the paint onto the wall. Therefore, in order to ensure the uniformity of the spraying, the spray gun is continuously swung to simulate the manual spraying process, so that the sprayed paint can be fully and evenly covered on the wall. The improvement of this utility model is as follows:
[0061] It also includes a drive structure that drives the long spray pipe 13 to reciprocate; specifically, the left and right ends of the long spray pipe 13 are respectively fixedly connected to slide rail rods 14, and correspondingly, the left and right ends of the lower sliding bracket 11 are respectively fixedly connected to guide sleeves 141 that slide and connect to the slide rail rods 14.
[0062] Meanwhile, in order to achieve the left and right linear swing of the long spray pipe 13 carrying the nozzle 15, the aforementioned drive structure 16 includes a push link 161 hinged to the right slide rail 14 (the specific hinge method is: a hinge slot is opened at the end of the slide rail 14 in this part, and the inner end of the push link 161 is hinged in the hinge slot by means of a pin). According to the existing method, it also includes a motor 163 fixedly installed in the lower sliding bracket 11. The output shaft of the motor 163 is fixedly connected to a turntable 162. The push link 161 is hinged at the eccentric position of the turntable 162 (similarly, at the eccentric position of the turntable 162, it is hinged to the other end of the push link 161 by means of a pin).
[0063] During operation, driven by motor 163, the rotating turntable 162 continuously pushes the long spray pipe 13, carrying the nozzle 15, to swing left and right in a linear fashion via the push rod 161. The paint sprayed from the nozzle 15 then covers the wall in this oscillating manner, improving the spraying quality and ensuring the uniformity of the paint coverage, including thickness. For example, when spraying waterproof coatings, this method ensures the quality of waterproofing work. Motor 163 is fixed to the right end of the lower sliding bracket 11 using the existing fixing method. In actual operation, the motor's power cord can be lowered under operator control during the entire device's descent, or the power cord can be directly attached to the pull rope 33 and lowered synchronously with the pull rope.
[0064] According to the existing method of pumping paint, the top right side of the long spraying pipe 13 is connected to the pumping inlet pipe 131. The pumping inlet pipe 131 is connected to the pumping pump (not shown in the figure) through a hose (specifically, the hose and the pumping inlet pipe are connected by a flange). The pumping pump is used to pump the paint into the long spraying pipe 13.
[0065] Specifically, similar to existing spraying principles, the paint is contained in a material tank (not shown in the figure), and the paint is pumped out by a material pump.
[0066] In actual operation, the operator coils the hose for pumping the paint around the roof, and as the entire unit is lowered, the hose gradually lengthens. During operation, the operator assists by supporting the hose (as the length of the entire unit increases during lowering, supporting the hose to ensure that the hose can be lowered synchronously and in coordination) to ensure smooth pumping of the paint.
[0067] As the long spray pipe 13 oscillates left and right, the pump feed pipe oscillates synchronously left and right. Therefore, the top of the lower sliding bracket 11 has a long sliding port 111 that cooperates with the pump feed pipe, and the pump feed pipe 131 passes through the long sliding port 111. The slightly swaying hose maintains high stability with the support of the operator.
[0068] Example 3
[0069] like Figure 1-6 As shown, this embodiment, based on the structure of embodiment 2, improves upon the following to ensure the stability of the entire device during the downward spraying process and prevent shaking. This is primarily because during spraying, the high-pressure nozzle 15 sprays paint instantaneously, generating a reverse impact force. Simultaneously, the device is also affected by wind, causing it to shake. Therefore, this invention is improved as follows:
[0070] The spraying mechanism 1 also includes a lower guide rope structure to prevent the lower guide rope support 11 from swaying; specifically, the lower guide rope structure includes two lower guide ropes 2 spaced apart on the left and right; the top of the lower guide ropes 2 is similarly hooked and anchored to the roof railing 4. The anchoring method is the same as that of the motor base 31, with a lower guide rope fixing bracket 22 hooked to the top of the lower guide rope 2, and the lower guide rope fixing bracket 22 is fixedly installed on the railing 4 on the roof of the building.
[0071] The rope fixing bracket 22 can specifically include an anchor rod, an anchor plate welded on the anchor rod, a pair of screw rods B welded on the mounting plate, a tension plate A inserted between the screw rods B after the guardrail rods 4 pass through the screw rods B, locking the guardrail rods 4 between the mounting plate and the tension plate A, and then tightening the locking nut.
[0072] Meanwhile, to ensure that the lower rope 2 is in a vertically tensioned position (the lower rope 2 is more stable when tensioned), specifically, the bottom of the lower rope 2 is tensioned and anchored to the ground; the anchoring method is as follows: a drill rod is driven into the ground in the existing manner, and then the lower rope 2 is fixed to the drill rod. During the fixing process, the lower rope 2 is pulled taut to maintain the tensioned state.
[0073] In conjunction with the lower sliding rope 2, a guide pulley structure 21 for guiding the lower sliding rope 2 is fixedly mounted on the aforementioned lower sliding bracket 11. Specifically, pulley structures 21 that cooperate with the lower sliding rope 2 are fixedly installed at both outer ends (rear sidewalls) of the lower sliding bracket 11; the lower sliding rope 2 is positioned on the outer (rear) side of the lower sliding bracket 11. Therefore, the lower sliding bracket 11 is always pressed against the wall and between it and the lower sliding rope 2. The lower sliding rope 2 always presses the lower sliding bracket 11 against the wall (in actual anchoring, the bottom of the lower sliding rope 2 can be anchored closer to the wall to generate inward tension, increasing the stability of the lower sliding bracket 11).
[0074] The guide roller structure 21 includes a guide roller bracket fixedly connected to the lower sliding bracket 11; a pair of guide rollers 213 are rotatably connected inside the guide roller bracket, and an annular guide groove is provided on the outline of the guide rollers 213. The lower sliding rope 2 is limited between the annular guide grooves of the pair of guide rollers 213.
[0075] During the entire process of the device sliding down, the guide pulley 213 rolls relative to the sliding rope 2, while the sliding rope 2 is limited within the guide pulley 213. Therefore, the limiting effect between the guide pulley 213 and the sliding rope 2 achieves the effect of preventing slippage.
[0076] Even under wind conditions, the entire device, through the structural design of the guide pulley 213 and the lower rope 2, is highly stable and not easily loosened or blown away by the wind.
[0077] In actual operation, the lower rope 2 can be further tensioned in windy conditions.
[0078] The aforementioned guide roller bracket includes a U-shaped bracket portion 212 welded and fixed to the lower sliding bracket 11, a roller bracket portion 213 welded to the U-shaped bracket portion 212, and a guide roller 213 rotatably connected to the roller bracket portion 213.
[0079] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
