Description

Technical Field

[0001] This utility model relates to the field of scaffolding production technology, specifically to a spraying device for producing steel plates for horizontal poles of scaffolding. Background Technology

[0002] Horizontal steel plates for scaffolding are crucial components connecting the vertical poles and enhancing the overall stability of the scaffolding. They are typically made of stamped or welded steel plates of a certain thickness and are fixed to the vertical poles by bolts or welding. They provide reliable support points for the horizontal poles, effectively transfer loads, and prevent scaffolding deformation, making them a key component for ensuring construction safety. During the production of horizontal steel plates for scaffolding, a spraying device is used to coat the surface of the steel plates.

[0003] Existing spraying devices for producing steel plates for scaffold horizontal poles typically place the steel plates on a conveyor belt and use spraying components for spraying. During spraying, the spraying components spray atomized paint onto the surface of the steel plates. At this time, the atomized paint tends to diffuse to both sides of the steel plates, i.e., to both sides of the conveyor belt, which can easily lead to contamination of the spraying device. At the same time, the diffusion of atomized paint can easily affect the operators' spraying operations. To address this, we propose a spraying device for producing steel plates for scaffold horizontal poles. Utility Model Content

[0004] The purpose of this utility model is to provide a spraying device for the production of steel plates for horizontal poles of scaffolding, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a spraying device for producing steel plates for horizontal poles of scaffolding, comprising a frame, a conveyor belt at the top of the frame, a drive motor cooperating with the conveyor belt at the side wall of the frame, a support column fixedly connected to the top of the frame, a top plate fixedly connected to the top of the support column, a liquid inlet embedded at the top of the top plate, a spraying assembly at the bottom of the liquid inlet, a sliding member 1 and a sliding member 2 slidably fitted externally to the spraying assembly, a support arm 1 on both sides of the sliding member 1, a support arm 2 on both sides of the sliding member 2, a sliding opening at the top of the top plate, a slider cooperating with the support arm 1 and the support arm 2 inside the sliding opening, and a stop block fixedly connected to the bottom of the spraying assembly.

[0006] Preferably, the slider sidewall is provided with a telescopic rod, and the telescopic rod sidewall is provided with a mounting block fixed to the liquid inlet.

[0007] Preferably, the sliding member has a roller inside, and the top of the spraying assembly has a groove that matches the roller.

[0008] Preferably, a fixing piece is provided at the bottom of the sliding member, and a deformation piece is provided on the rear side wall of the fixing piece.

[0009] Preferably, the side wall of the fixing piece is fitted with a baffle, and the baffle is provided with inclined plates on both sides.

[0010] Preferably, rubber strips are provided on both sides of the deformable sheet, and a snap-fit ​​component is fixedly connected to the side wall of the deformable sheet and snap-fitted to the baffle.

[0011] Preferably, a baffle is fixed to the side wall of the fixing plate, and the baffle is fitted to the side wall of the spraying assembly.

[0012] Preferably, a connecting ring is provided on one side wall of the support arm, and the first support arm is fitted to the side wall of the second support arm.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This invention, when the horizontal steel plate of the scaffolding is placed on the conveyor belt for spraying, allows for the setting of the spraying width of the spraying component according to the size of the steel plate. The telescopic rod is then controlled to extend and retract, causing the slider to move to both ends. This rotation of support arms one and two causes sliding parts one and two to move towards the center in conjunction with the spraying component. The baffle is positioned on the outer side of the top of the horizontal steel plate of the scaffolding. The baffle can then shield the material sprayed by the spraying component, reducing the diffusion of atomized paint to both sides of the frame during spraying. This improves the cleanliness of both sides of the frame during use of the spraying device for producing horizontal steel plates of the scaffolding, and reduces the outward diffusion of atomized paint.

[0015] 2. When the baffle needs to be replaced, the telescopic rod can be retracted, causing the sliding member to move outward. Then, the abutment can pass through the fixed piece and abut against the deformation piece, causing the deformation piece to move backward and deform. As a result, the locking piece will deform inward, causing the baffle and the locking piece to disengage. At this time, the baffle can be easily removed for replacement, thereby improving the convenience of the baffle during use. During installation, simply hold the deformation piece so that the locking piece can be engaged with the locking hole of the baffle. Attached Figure Description

Detailed Implementation

[0022] 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. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0023] Please see Figures 1-5 The figure shows a spraying device for producing steel plates for horizontal poles of scaffolding, including a frame 100, a conveyor belt 110 at the top of the frame 100, and a drive motor 111 that works with the conveyor belt 110 on the side wall of the frame 100. The drive motor 111 uses a motor commonly used in the market for conveyor belts 110, which is existing technology. A support column 120 is bolted to the top of the frame 100, and a top plate 121 is bolted to the top of the support column 120. A liquid inlet 130 is embedded in the top of the top plate 121.

[0024] In some embodiments, the liquid inlet 130 is internally provided with a liquid pipe connected to the spraying assembly 140. The input end of the liquid inlet 130 is connected to a common pressure pump and a paint tank that works in conjunction with the pressure pump's input end. The pressure pump pressurizes the paint in the paint tank and delivers it to the spraying assembly 140 through the liquid inlet 130. The bottom of the spraying assembly 140 is embedded with multiple commercially available electric paint nozzles, which are electrically connected to a commercially available external programmable controller. By controlling the number of paint nozzles used, the spraying width of the spraying assembly 140 is controlled, and the width is centrally symmetrical. Simultaneously, a common fiber optic photoelectric sensor, electrically connected to the programmable controller, can be embedded at the center of the bottom of the spraying assembly 140. This fiber optic photoelectric sensor consists of a light source, optical fiber, photodetector, and signal processing circuitry. When the top of the conveyor belt 110 senses a steel plate, it transmits data to the programmable controller, which then controls the paint nozzles to open for spraying.

[0025] The bottom of the liquid inlet 130 is provided with a spraying assembly 140. The spraying assembly 140 is externally slidably fitted with a first sliding member 150 and a second sliding member 154. The first sliding member 150 and the second sliding member 154 are arranged opposite to each other. The first sliding member 150 is rotatably connected to a first support arm 152 on both sides. The second sliding member 154 is provided with a second support arm 155 on both sides. The top plate 121 has a sliding opening 122 at the top. The sliding opening 122 is provided with a slider 133 rotatably connected to the first support arm 152 and the second support arm 155 inside. The bottom of the spraying assembly 140 is fixedly connected with a stop block 142 that cooperates with the fixed piece 160. When the stop block 142 abuts against the deformation piece 162, the deformation piece 162 deforms and displaces backward, causing the locking piece 161 to deform inward, so that the baffle 170 disengages from the locking piece 161.

[0026] Specifically, the slider 133 has a telescopic rod 132 on its side wall. The telescopic rod 132 is a commercially available electric push rod with an external reversing switch. The two telescopic rods 132 are electrically connected to the same external reversing switch. The side wall of the telescopic rod 132 has a mounting block 131 that is fixed to the liquid inlet 130 by bolts.

[0027] Furthermore, a roller 151 is provided inside the sliding component 150, and a groove 141 that matches the roller 151 is provided on the top of the spraying assembly 140.

[0028] Furthermore, a fixing plate 160 is tightly welded to the bottom of the sliding member 150, and a deformation plate 162 is provided on the rear side wall of the fixing plate 160. The deformation plate 162 and the snap-fit ​​member 161 are made of elastic stainless steel.

[0029] Furthermore, the side wall of the fastener 160 is fitted with a baffle 170, the side wall of the baffle 170 is provided with a snap-fit ​​hole that fits with the snap-fit ​​part 161, and the baffle 170 is provided with beveled plates 172 on both sides. The baffle 170 and the beveled plates 172 are made of commonly available hard plastic sheets.

[0030] Furthermore, rubber strips 163 are provided on both sides of the deformable piece 162. The rubber strips 163 are made of highly elastic rubber. A snap-fit ​​member 161 is fixedly connected to the side wall of the deformable piece 162 and snaps onto the baffle 170. At the same time, the side wall of the fixed piece 160 is machined with a mating groove that matches the snap-fit ​​member 161 and a hole in the abutment block 142, so that the abutment block 142 can pass through the mating groove and abut against the deformable piece 162, while the snap-fit ​​member 161 can deform within the hole.

[0031] It is worth noting that the side wall of the fixing plate 160 is fixed with a baffle 156 by bolts, and the baffle 156 is fitted to the side wall of the spraying assembly 140.

[0032] It is worth noting that a connecting ring 153 is provided on the side wall of support arm 152, and support arm 152 is fitted to the side wall of support arm 2 155.

[0033] In addition, all the electrical components and equipment mentioned above use external power sources. The circuits, electronic components, and modules involved in this utility model are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. Furthermore, the scope of protection of this utility model does not involve improvements to the internal structure and methods.

[0034] Working principle: When the horizontal steel plate of the scaffolding is placed on the conveyor belt 110 for spraying, the spraying width of the spraying component 140 can be set according to the size of the steel plate. Then, the telescopic rod 132 is controlled to extend and retract, causing the slider 133 to move to both ends. This causes the support arm 152 and support arm 155 to rotate, prompting the sliding parts 150 and 154 to move towards the center with the spraying component 140. This positions the baffle 170 on the outer side of the top of the horizontal steel plate of the scaffolding. The baffle 170 can then be used to shield the material sprayed by the spraying component 140, reducing the diffusion of the atomized paint to both sides of the frame 100 during spraying, thus facilitating the lifting of the scaffolding. When using the spraying device for producing horizontal steel plates, the cleanliness of both sides of the frame 100 is improved, reducing the diffusion of atomized paint to the outside. When the baffle 170 needs to be replaced, the telescopic rod 132 can be retracted, causing the sliding member 150 to move outward. Then, the abutment 142 can pass through the fixed piece 160 and abut against the deformation piece 162, causing the deformation piece 162 to move backward and deform. As a result, the locking member 161 will deform inward, causing the baffle 170 and the locking member 161 to disengage. At this time, the baffle 170 can be easily removed and replaced, thereby improving the convenience of using the baffle 170. During installation, simply hold the deformation piece 162 so that the locking member 161 can be locked into the locking hole of the baffle 170.
