Description

Technical Field

[0001] This invention relates to a working method, and more particularly to a working method for a safety protection device applied to a spray booth, which belongs to the technical field of spray booth protective equipment. Background Technology

[0002] A spray booth generally refers to a paint booth, which, as the name suggests, is a room where filtered and painted objects are sprayed and colored. It is also called a paint baking booth. A paint booth is a device that provides a dedicated environment for painting operations, meeting the requirements of painting operations for temperature, humidity, light intensity, air cleanliness, etc. It can limit and treat the paint mist and organic waste gas generated during the painting operation before releasing them, making it an environmentally friendly painting equipment.

[0003] Workpieces to be painted are usually suspended from the ceiling in the spray booth. Workers then use handheld spraying equipment to paint the suspended workpieces. However, if a workpiece accidentally falls while the worker is spraying below, it can easily cause injury. Therefore, it is necessary to install a safety protection device.

[0004] Existing protective devices typically have support columns installed at the bottom of the workpiece to support it in case it falls accidentally. However, these are mostly fixed installations with a fixed distance between them. If the suspended workpiece is too large or too small, the support columns cannot adequately support the falling workpiece and may directly injure the workers below. In addition, because the contact area between the top of the support column and the workpiece is small, there is a risk of the workpiece falling to the top of the support column and then falling again. Summary of the Invention

[0005] The purpose of this invention is to overcome the above-mentioned shortcomings in the prior art and to provide a working method for a safety protection device for spray booths that has a reasonable structural design, is safe and reliable, reduces the harm to operators caused by workpiece falling off, and is easy to operate.

[0006] The technical solution adopted by this invention to solve the above problems is: a working method of a safety protection device applied to a spray booth. The safety protection device includes an adjustment mechanism, a support mechanism, a low platform set at the bottom of the spray booth, and a workpiece suspended at the top of the spray booth. A ventilation duct for ventilation and a protective mechanism for protection are provided on the low platform below the workpiece. A bumper is vertically installed inside the ventilation duct. The protective mechanism includes two symmetrically arranged support columns connected by an adjustment mechanism. A support mechanism is fixed at the top of each support column, and a load-bearing block is fixed at the bottom of each support column. A movable wheel is provided on the load-bearing block, and a foot brake is provided on the movable wheel. The specific steps of the working method are as follows: In use, according to the size of the suspended workpiece, adjust the adjustment mechanism... The protective mechanism is moved to a designated location via casters. Then, the electrically controlled cylinders on the mechanism are adjusted, and the distance between the two support columns is changed through the coordinated operation of various components, adjusting the protective mechanism to an appropriate length according to the workpiece size. Correspondingly, based on the length of the protective mechanism, the length of the support mechanism is adjusted through the engagement of gears with the first and second racks, creating a gap between the two support mechanisms. When the workpiece falls, it lands smoothly on the support mechanism, reducing the possibility of secondary falls. After adjustment, the entire protective mechanism is secured by stepping on the brake pads. If the workpiece falls during painting, the protective mechanism and the bumper installed in the ventilation duct will support it, reducing the risk of injury to the worker.

[0007] Preferably, the adjusting mechanism of the present invention includes a first mounting groove and a second mounting groove. The first mounting groove has first sliding grooves on both sides, and a first slider is slidably connected within each first sliding groove. A first connecting plate is connected between the first sliders via a rotating shaft. Two first connecting rods are also rotatably arranged within the first mounting groove, with the middle portion of each first connecting rod connected to the first connecting plate via a rotating shaft. The second mounting groove has second sliding grooves on both sides, and a second slider is slidably arranged within each second sliding groove. A second connecting plate is connected between the second sliders via a rotating shaft. Two second connecting rods are also rotatably arranged within the second mounting groove, with the middle portion of each second connecting rod connected to the second connecting plate via a rotating shaft. The ends of the second connecting rods are rotatably connected to the ends of the first connecting plates, and the ends of the second connecting plates are rotatably connected to the ends of the first connecting rods.

[0008] Preferably, the support mechanism of the present invention includes a support cavity, a gear, a first rack, a second rack, a first support block, and a second support block. The gear is connected inside the support cavity via a rotating shaft. The first rack and the second rack are symmetrically meshed on the gear. The first support block is provided on the outer end of the first rack, and the second support block is provided on the outer end of the second rack. Both the first support block and the second support block are slidably connected to the support cavity.

[0009] Preferably, the present invention also includes an electrically controlled cylinder, wherein an electrically controlled cylinder is provided in the first mounting groove near the first connecting rod, and the output end of the electrically controlled cylinder is connected to the rotating shaft between the first slider.

[0010] Preferably, the present invention also includes a drive motor, through which the gear is driven.

[0011] Preferably, the present invention further includes a shock-absorbing pad, and a layer of shock-absorbing pad is laid on the top of the support cavity, the first support block and the second support block.

[0012] Compared with the prior art, the present invention has the following advantages and effects: the overall structure is reasonably designed and easy to operate. With the protective mechanism and the bumper set in the air duct, the workpiece can be supported when it falls off accidentally, so as to reduce the injury to the operator caused by the workpiece falling off.

[0018] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. The following embodiments are explanations of the present invention, but the present invention is not limited to the following embodiments.

[0019] Example

[0020] like Figure 1 , Figure 2As shown, the safety protection device applied to the spray booth in this embodiment includes a low platform 1 set at the bottom of the spray booth and a workpiece 2 suspended at the top of the spray booth. On the low platform 1, below the workpiece 2, there is a ventilation duct 3 for ventilation and a protective mechanism 4 for protection. A bumper 5 is vertically installed inside the ventilation duct 3. The protective mechanism 4 is at the same height as the bumper 5. If the workpiece falls off, it can be used to support the workpiece and protect the workers, thereby reducing the injury to the workers. The ventilation duct 3 is used for ventilation, and the internal bumper 5 can also reduce the damage to the ventilation duct 3 caused by the workpiece falling off.

[0021] like Figure 2 , Figure 3 As shown, the protective mechanism 4 includes two symmetrically arranged support columns 6, which are connected by an adjustment mechanism 7. A support mechanism 8 is fixedly installed at the top of the support column 6, and a load-bearing block 9 is fixedly installed at the bottom of the support column 6. The load-bearing block 9 is equipped with a movable wheel 10, and a foot brake pad 11 is installed on the movable wheel 10. The protective mechanism 4 can adjust the distance between the support columns 6 by adjusting the adjustment mechanism 7, thereby adjusting the length of the protective mechanism 4 according to the size of the workpiece. The support mechanism 8 can support the workpiece after it falls off. The movable wheel 10 facilitates the movement of the entire device, thus facilitating handling and placement. The foot brake pad 11 and the load-bearing block 9 are used for fixation to increase stability.

[0022] like Figure 3As shown, the adjustment mechanism 7 includes a first mounting groove 12 and a second mounting groove 13. The first mounting groove 12 has first sliding grooves 14 on both sides, and first sliders 15 are slidably connected within the first sliding grooves 14. A first connecting plate 16 is connected between the first sliders 15 via a rotating shaft. Two first connecting rods 17 are also rotatably mounted within the first mounting groove 12, with the middle portion of each first connecting rod 17 connected to the first connecting plate 16 via a rotating shaft. The second mounting groove 13 has second sliding grooves 18 on both sides, and second sliders 19 are slidably mounted within the second sliding grooves 18. A second connecting plate 20 is connected between the second sliders 19 via a rotating shaft. Two second connecting rods 21 are rotatably arranged in the second mounting groove 13. The middle part of the second connecting rod 21 is connected to the second connecting plate 20 via a rotating shaft, and the end of the second connecting rod 21 is rotatably connected to the end of the first connecting plate 16. The end of the second connecting plate 20 is rotatably connected to the end of the first connecting rod 17. An electric cylinder 22 is also provided in the first mounting groove 12 near the first connecting rod 17. The output end of the electric cylinder 22 is connected to the rotating shaft between the first sliders 15. Two mounting slots are fixedly installed on the inner sides of the two support columns 6. By extending and retracting the electric cylinder 22, the first slider 15 can be moved within the first sliding groove 14. With the cooperation of components such as the first connecting plate 16, the first connecting rod 17, the second connecting plate 20, and the second connecting rod 21, the second slider 19 will also slide within the second sliding groove 18. This changes the distance between the first mounting slot 12 and the second mounting slot 13, thereby changing the distance between the two support columns 6, which facilitates the adjustment of the length of the protective mechanism 4. When the electric cylinder 22 extends, it pushes the first slider 15 to move outward. With the linkage of each component, the two connecting plates and connecting rods will rotate inward, so that the second mounting slot 13 will move towards the first mounting slot 12 to shorten the distance. When the electric cylinder 22 retracts, the first slider 15 slides inward. Due to the linkage of each component, the two connecting plates and connecting rods will rotate outward in the opposite direction, which can push the second mounting slot 13 away from the first mounting slot 12 to increase the distance.

[0023] like Figure 4 As shown, the support mechanism 8 includes a support cavity 23, a gear 24, a first rack 25, a second rack 26, a first support block 27, and a second support block 28. The gear 24 is connected to the inside of the support cavity 23 via a rotating shaft. The gear 24 is driven by a drive motor 29. The first rack 25 and the second rack 26 are symmetrically meshed on the gear 24. The first support block 27 is provided on the outer end of the first rack 25, and the second support block 28 is provided on the outer end of the second rack 26. The first support block 27 and the second support block 28 are slidably connected to the support cavity 23. A layer of shock-absorbing pad 30 is laid on the top of the support cavity 23, the first support block 27, and the second support block 28.

[0024] The support cavity 23, the first support block 27, and the second support block 28 are all used to support the falling workpiece 2. The shock-absorbing pads 30 on these blocks are used to absorb shock and reduce the impact force during the fall, allowing the workpiece to land smoothly on the support mechanism 8. Through the drive of the drive motor 29 and the engagement of the gear 24 and the two racks, the lengths of the support cavity 23, the first support block 27, and the second support block 28 can be changed, allowing for adjustment according to the length of the protective mechanism 4 to increase the contact area between the support mechanism 8 and the workpiece. When the protective mechanism 4 is short, the engagement of the gear 24 and the racks allows the first support block 27 and the second support block 28 to be retracted into the support cavity 23, supporting the workpiece 2 only through the support cavity 23. When the protective mechanism 4 is long, the drive motor 29 can drive the gear 24 to rotate in the opposite direction, thereby moving the two support blocks outwards to correspondingly increase the length of the support mechanism 8, thus better supporting the workpiece 2 and reducing the occurrence of secondary workpiece detachment.

[0025] The working process of the safety protection device applied to the spray booth in this embodiment is as follows: In use, according to the size of the suspended workpiece, the protective mechanism 4 is moved to the designated location by the moving wheels 10. Then, the electric control cylinder 22 on the mechanism 7 is adjusted to drive the device. Through the linkage of the components on the mechanism, the distance between the two support columns 6 is changed, and the protective mechanism 4 can be adjusted to an appropriate length according to the size of the workpiece. Then, according to the length of the protective mechanism 4, the length of the support mechanism 8 is adjusted by the cooperation of the gear 24 and the two racks, so that there is a gap between the two support mechanisms 8. When the workpiece 2 falls off, the workpiece 2 falls smoothly onto the support mechanism 8, reducing the occurrence of secondary fall of the workpiece 2. After the adjustment is completed, the entire protective mechanism 4 is fixed by stepping on the brake pad 11, and the worker can then spray paint the workpiece 2. If the workpiece 2 falls off during spraying, the protective mechanism 4 and the bumper 5 set in the ventilation duct 3 will support the workpiece 2 together to reduce the injury caused to the worker by the workpiece 2 falling off.
