Description

Technical Field

[0001] This utility model relates to the field of auxiliary tool technology, specifically a safety and work treadmill for use in a paint spray booth. Background Technology

[0002] In the spray booth operation scenario of a suspended painting line, there are several safety hazards and operational inconveniences when spraying large workpieces, specifically: 1. Currently, workers typically use a side lifting platform to spray large workpieces from above. However, this method has significant limitations; the side lifting platform cannot reach the top center of the workpiece. Using an extension pole is extremely inconvenient and severely impacts work efficiency. In such situations, some workers risk climbing to the top of the workpiece to complete the spraying task, posing a significant safety risk; 2. When a workpiece falls, it may roll irregularly, easily injuring nearby workers and posing a serious safety threat. Utility Model Content

[0003] In view of the shortcomings of the existing technology, this utility model provides a safety and work trestle for spray booths, which solves the technical problems of low work efficiency and high safety risks when spraying large workpieces.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a safety and work trestle for a paint spraying booth, comprising two sets of bases, two sets of columns welded on the bases, and a crossbeam welded between the two sets of columns arranged opposite to each other. An upper step plate is welded to one side of the crossbeam, and a movable folding mechanism is hinged to the side wall of the base, with a lower step plate hinged between the two sets of movable folding mechanisms.

[0005] The movable folding mechanism includes a height adjustment component installed on the side wall of the column. The height adjustment component is movably connected to a second hinge frame via a first hinge frame. A third hinge frame is provided on one side of the second hinge frame. The two ends of the second and third hinge frames are respectively hinged to the side walls of the base and the lower step plate.

[0006] Preferably, the height adjustment component includes a threaded rod, which is fixedly connected to a groove on the side wall of the column. A limiting block and a slider are sleeved on the threaded rod and slide within the groove. The limiting block is located below the slider. A nut located at the bottom of the limiting block is also threadedly connected to the threaded rod.

[0007] Preferably, a reinforcing column is welded between the base and the column, and a supporting column connected to the bottom of the upper step plate is welded onto the reinforcing column.

[0008] Preferably, the base, the lower step plate, the second hinge frame, and the third hinge frame form a parallelogram structure.

[0009] Preferably, the base is equipped with self-locking wheels near both ends of its bottom.

[0010] Preferably, both the upper and lower step plates are embedded with galvanized gratings.

[0011] By means of the above technical solution, this utility model provides a safety and work treadmill for paint spraying booths, which has at least the following beneficial effects:

[0012] This spray booth uses a dual-purpose safety and work trestle, designed with a "stepped" structure on both sides. Standing on the upper step is prohibited; it acts as a buffer against workpiece detachment and fall. The lower step serves as a step for workers to reach higher parts of the workpiece during spraying, avoiding the safety risks of workers climbing onto the top of the workpiece in actual production. Simultaneously, the booth features self-locking wheels that allow it to move along a pre-set track, facilitating continuous spraying of long workpieces and increasing on-site production flexibility. It effectively reduces the safety risks of workpiece detachment and fall, as well as the safety risks of workers climbing onto the top of workpieces, while also facilitating workers' access to higher areas. Its excellent applicability and improved spraying efficiency are key advantages.

[0013] The spray booth uses a dual-purpose safety and work trestle. With a movable folding mechanism, the lower step can be moved out when in use and retracted when not in use, thus reducing the overall space occupied by the booth.

[0014] This paint booth uses a dual-purpose safety and work trestle. By setting up a height adjustment component, the height of the lower step plate can be adjusted according to the lifting height of the workpiece, making it more practical. 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.

[0023] A suspended painting line is a type of production line used for coating workpiece surfaces. Its core feature is the use of suspension devices to suspend the workpieces, allowing them to move in a suspended state within the production line to complete a series of coating processes. In this line, large workpieces are typically suspended from conveyor tracks using hooks or other hanging tools, passing sequentially through processing areas such as spray booths as the tracks move. This type of production line is suitable for coating large workpieces, making full use of space and achieving continuous, automated production.

[0024] Due to the inherent technical shortcomings of existing technologies, such as low operational efficiency and high safety risks, please refer to... Figures 1-4This embodiment provides a dual-purpose (safety and work) trestle for spray booths, which can reduce the safety risk of workpieces falling and injuring people to a certain extent, and avoid the safety risk of workers climbing on top of workpieces. It also facilitates workers' access to heights, has good applicability, and can improve spraying efficiency. The trestle includes two sets of bases 1, with two sets of uprights 2 welded to the bases 1. A crossbeam 3 is welded between the two opposing sets of uprights 2. An upper step plate 4 is welded to one side of the crossbeam 3. A movable folding mechanism 7 is hinged to the side wall of the bases 1, and a lower step plate 8 is hinged between the two sets of movable folding mechanisms 7. The overall design is a "two-sided step" structure. No one is allowed to stand on the upper step plate 4, which acts as a buffer against workpiece falling. The lower step plate 8 serves as a step for workers to reach higher areas while spraying the workpiece, preventing actual... There are safety risks associated with workers climbing to the top of workpieces during production; however, the movable folding mechanism 7 can fold and store the lower step plate 8, reducing space occupation and facilitating flexible movement within the paint spraying room. Specifically, the movable folding mechanism 7 includes a height adjustment component 701 mounted on the side wall of the column 2. The height adjustment component 701 is movably connected to a second hinge frame 703 via a first hinge frame 702. A third hinge frame 704 is provided on one side of the second hinge frame 703. The two ends of the second hinge frame 703 and the third hinge frame 704 are respectively hinged to the side wall of the base 1 and the lower step plate 8. Under the action of the second hinge frame 703 and the third hinge frame 704, the lower step plate 8 can be moved out by pulling. The first hinge frame 702 is used to limit the lower step plate 8, keeping it fixed in the appropriate position after it has been moved.

[0025] Due to the varying heights of the workpieces, the fixed-position lower step plate 8 is insufficient to meet practical application requirements. Therefore, please refer to... Figure 3 The height adjustment assembly 701 includes a threaded rod 7011, which is fixedly connected to a groove on the side wall of the column 2. A limiting block 7012 and a slider 7014 are fitted onto the threaded rod 7011 and slide within the groove. The limiting block 7012 is located below the slider 7014. A nut located at the bottom of the limiting block 7012 is also threaded onto the threaded rod 7011. When the lower step plate 8 is unfolded, the hinge bracket 702 pulls the slider 7014. When the slider 7014 moves downward, it can no longer move downward after contacting the limit block 7012, thus holding the lower step plate 8 and keeping it stable. When it is necessary to adjust the height of the lower step plate 8, the limit block 7012 is moved by turning the nut. When the limit block 7012 moves upward, the height of the upper step plate 4 at the fixed position can be increased. When the limit block 7012 moves downward, the height of the upper step plate 4 at the fixed position can be decreased.

[0026] When a workpiece detaches and falls, it will first come into contact with the upper step plate 4. Therefore, it is necessary to improve the impact resistance of the upper step plate 4. Thus, a reinforcing column 5 is welded between the base 1 and the column 2. A support column 6 connected to the bottom of the upper step plate 4 is welded onto the reinforcing column 5. The reinforcing column 5 and the support column 6 between the base 1 and the column 2 enhance the overall structural strength of the trestle, can withstand the impact when the workpiece falls, and act as a buffer structure to reduce the risk of injury.

[0027] Furthermore, the base 1, the lower step plate 8, the second hinge frame 703, and the third hinge frame 704 form a parallelogram structure; this ensures that the lower step plate 8 remains horizontal during the unfolding process, improving the stability of the worker's standing position.

[0028] Existing trestles are usually fixed and cannot be moved within the spray booth. When dealing with continuous spray painting of long workpieces, the equipment needs to be disassembled and reassembled multiple times, resulting in low efficiency. To address this issue, self-locking wheels 9 are installed on the bottom of the base 1 near both ends. The self-locking wheels 9 facilitate the movement of the entire unit on a pre-set track, adapting to continuous spray painting of long workpieces, improving production flexibility, and the self-locking function can fix the overall position during operation, preventing slippage and ensuring operational safety.

[0029] The existing trestle steps have poor anti-slip performance, making it easy for workers to slip and fall during spraying operations. Especially in the paint spraying environment, paint residue may exacerbate the risk of slipping. To address this issue, galvanized grating 10 is embedded in both the upper step plate 4 and the lower step plate 8. This can enhance surface friction, prevent workers from slipping and improve work safety. In addition, the galvanized grating 10 has corrosion resistance, is suitable for the paint spraying environment, extends the service life of the trestles, and reduces maintenance costs.
