Description

Technical Field

[0001] This utility model belongs to the field of lifting platform technology, and specifically relates to a lifting operation platform. Background Technology

[0002] Lifting platforms can be divided into fixed and mobile types. Mobile lifting platforms include straight boom, articulated boom, scissor lift, mast, and telescopic cylinder types. Fixed lifting platforms include guide rail and chain types. The top of the platform of the lifting platform is usually equipped with a guardrail to ensure the safety of the device. However, in practical applications, when the existing lifting work platform is close to or adjacent to a wall for large-area surface operations such as painting or tiling, the guardrail will directly block the work area and reduce the working range. Operators need to frequently start the lifting mechanism to adjust the overall position of the platform to avoid the obstruction, which not only interrupts the continuity of work, but also increases the number of times the mechanism is started and stopped and the energy consumption of the equipment. On the other hand, during operations such as drilling holes in walls and partial spraying, if there is a gap between the area to be worked on and the workbench, tools and debris can easily fall through the gap, polluting the environment and threatening the safety of personnel and equipment on the ground. Utility Model Content

[0003] The purpose of this utility model is to provide a lifting work platform that can improve work efficiency and safety.

[0004] The specific technical solution adopted by this utility model is as follows: A lifting work platform includes a lifting mechanism, which comprises a lower support base, a linear drive actuator, a scissor arm, and an upper mounting base. A worktable is mounted on the upper mounting base. Protective components are mounted on both ends and sides of the worktable. Each of the four protective components includes two support plates. Two support plates on two corresponding protective components are mounted on the worktable via an angle adjustment component. Two support plates on the other two protective components are fixedly connected to the worktable. The two support plates on each protective component are connected by a mounting plate. A protective plate is also mounted between the two support plates via a quick-release component. A protective stop is installed between the protective plate and the mounting plate. The quick-release component includes two positioning rods that slide inside the protective plate, and the two positioning rods are respectively inserted into the two support plates. The angle adjustment component includes a positioning block fixed to the outer bottom of the support plate. A support block is rotatably connected to the side of the positioning block away from the support plate, and the support block is fixedly connected to the worktable. The positioning block has multiple positioning through holes, and a positioning post is inserted into the inner side of one of the positioning through holes, and the positioning post is inserted into the worktable.

[0005] A rectangular plate that is slidably connected to the protective plate is fixed at one end of the two positioning rods that are close to each other, and a spring is provided between the two rectangular plates.

[0006] The technical effects achieved by this utility model are as follows: This utility model allows the protective plate and protective barrier to slide down quickly simply by pulling the positioning rod, eliminating the obstruction of the work area by the protective barrier and reducing the tedious operation of frequently adjusting the overall position of the workbench due to the obstruction of the protective barrier, thus improving construction efficiency. At the same time, when there is a gap between the work area and the workbench, the protective plate and protective barrier can be tilted and fitted towards the wall by rotating the support plate, reducing the gap between the protective structure and the work area, and reliably preventing paint residue, wall fragments and tools from falling during the operation, thereby taking into account both work efficiency and safety protection requirements.

[0009] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0010] like Figure 1-4 As shown, a lifting work platform includes a lifting mechanism consisting of a lower support seat 13, a linear drive actuator 14, a scissor arm 15 and an upper mounting seat 16, and a worktable 1 mounted on the upper mounting seat 16. The lower support 13, linear drive actuator 14, scissor arm 15 and upper mounting base 16 mentioned above are existing mature technologies. The linear drive actuator 14 is activated to extend and retract, raising and lowering the worktable 1 to a position matching the working height. In this embodiment, the lower support 13, linear drive actuator 14, scissor arm 15 and upper mounting base 16 will not be described in detail. See attached document Figure 1 and attached Figure 2 The workbench 1 is equipped with four protective components. The four protective components are arranged around the top of the workbench 1 in a circumferential manner to form a protective structure. Among them, the support plates 2 on the two protective components that are opposite each other along the length of the workbench 1 are installed on the workbench 1 through angle adjustment components. The two support plates 2 on the other two protective components are fixedly connected to the workbench 1. See attached document Figure 1 , 2 and attached Figure 3 The two support plates 2 on the protective assembly are connected by a mounting plate 12. A protective plate 3 is also installed between the two support plates 2 by a quick-release assembly. A protective stop 4 is fixed between the bottom of the protective plate 3 and the top of the mounting plate 12. It is a flexible sheet structure. The protective barrier 4 adopts a flexible sheet structure design and is made of PVC coated canvas that combines toughness and durability, and has good flexibility, tear resistance, waterproof and wear resistance. See attached document Figure 2 , 3 and attached Figure 4 The quick-release assembly includes two positioning rods 5 that slide through the inside of the protective plate 3. The protective plate 3 has a limiting groove adapted to the positioning rods 5. The two positioning rods 5 are located at both ends of the upper limit groove inside the protective plate 3. Each of the two support plates 2 in each protective component has a vertical through groove for the positioning rod 5. In use, the positioning rod 5 on each protective component is slidably connected to the protective plate 3 and inserted into the support plate 2 through the setting of the limiting groove and the through groove. When in use: when the workbench 1 is raised or lowered to the working height, so that the workbench 1 is close to or adjacent to the working area, one of the protective components set along the length of the workbench 1 is opposite to the working area. By pulling the two positioning rods 5 on this protective component to move in the opposite direction, the positioning rods 5 are disengaged from the support plate 2. The protective plate 3 slides naturally down along the inner side of the support plate 2 towards the support plate 2, and at the same time, the protective stop 4 is disengaged from the protective position. The working area that was originally covered by the protective stop 4 is then completely exposed, reducing the compression of the working range, reducing the need for operators to frequently start the lifting mechanism to adjust the overall position of the platform to avoid obstruction, and improving work efficiency. See attached document Figure 3 and attached Figure 4 To enable simultaneous driving of two positioning rods 5 with a single hand grip, a rectangular groove is provided on the surface of the protective plate 3. The ends of the two positioning rods 5 that are close to each other extend into the rectangular groove. A rectangular plate 6 is fixedly connected to the end of the positioning rod 5 inside the protective plate 3. The rectangular plate 6 and the protective plate 3 form a sliding fit through the rectangular groove. A spring 7 is also provided between the two rectangular plates 6 and inside the rectangular groove. The two ends of the spring 7 abut against the two rectangular plates 6 respectively. In use, the operator only needs to hold the two rectangular plates 6 on the protective plate 3 with one hand and apply force to the middle to drive the two positioning rods 5 to move inward simultaneously. While compressing the spring 7, the positioning rods 5 quickly disengage from the through groove of the support plate 2, realizing the rapid separation of the protective plate 3 and the support plate 2. The entire operation does not require the control of both hands, which significantly improves the ease of disassembly.

[0011] To prevent accidental movement of the positioning rod 5 due to accidental contact with the rectangular plate 6 when not in operation, a protective cover 11 is also attached to the protective plate 3. The protective cover 11 covers the outside of the two rectangular plates 6. When there is no need to move the positioning rod 5, the snap-fit ​​structure between the protective cover 11 and the protective plate 3 limits the rectangular plate 6 to the inside of the protective cover 11, preventing it from moving towards the middle. This effectively avoids the problem of the protective plate 3 detaching due to accidental contact or collision, and ensures the safety of the protective components.

[0012] See attached document Figure 2 and attached Figure 3 In each protective component, the two ends of the protective plate 3 extend to the inner side of the corresponding two support plates 2, and the side of the support plate 2 near the protective plate 3 is provided with a guide groove adapted to the protective plate 3. The guide groove is connected to the through groove. The two ends of the protective plate 3 are located inside the guide grooves opened on the corresponding two support plates 2. The guide groove provides guidance for the sliding of the positioning rod 5, which can reduce the offset of the protective plate 3 during the sliding process. See attached document Figure 1 , 2 and attached Figure 3 The angle adjustment component includes a positioning block 8 fixed on the outer side of the bottom of the support plate 2. A support block 10 is rotatably connected to the side of the positioning block 8 away from the support plate 2, and the support block 10 is fixedly connected to the top of the workbench 1. Multiple positioning through holes 17 are opened on the outer circumference of the positioning block 8. A positioning post 9 is inserted into the inner side of one of the positioning through holes 17. An insertion hole for the positioning post 9 is opened on the top of the workbench 1. The positioning post 9 and the workbench 1 are connected by the insertion hole. When in use: After the workbench 1 is raised to the working height, one of the protective components set along the length of the workbench 1 is opposite to the working area. If there is a gap between the area to be worked on and the workbench 1, tools and fragments are likely to fall through the gap during operation. At this time, the positioning pin 9 can be pulled out to release the limit on the positioning block 8. Rotate the support plate 2 to drive the entire adjustable protective assembly to rotate around the pivot of the positioning block 8 and the support block 10, so that the protective plate 3 and the protective stop 4 are tilted towards the wall until the outer side of the protective plate 3 is in contact with the tilted wall. Then insert the positioning pin 9 into the positioning through hole 17 and the insertion hole of the worktable plate 1 at the corresponding angle to fix the angle. By adapting the angle, the gap between the protective structure and the construction area is reduced, which can block paint residue, wall fragments generated by drilling, and workpieces from falling during operation. At the same time, it provides a protective barrier close to the work surface for operators, improving the safety of operation.

[0013] In summary, this utility model allows the protective plate 3 and the protective stop 4 to slide down quickly simply by pulling the positioning rod 5, eliminating the obstruction of the work area by the protective stop 4, reducing the tedious operation of frequently adjusting the overall position of the workbench 1 due to the obstruction of the protective stop 4, and improving construction efficiency. At the same time, when there is a gap between the work area and the workbench 1, the protective plate 3 and the protective stop 4 can be tilted and fitted towards the wall by rotating the support plate 2, reducing the gap between the protective structure and the work area, and reliably preventing paint residue, wall fragments and tools from falling during the operation, thus taking into account both work efficiency and safety protection requirements.

[0014] The above are merely preferred embodiments of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
