Description

Technical Field

[0001] This invention relates to the field of scissor cart safety assistance technology, specifically a scissor cart safety assistance device. Background Technology

[0002] Scissor lift safety auxiliary devices refer to equipment installed on scissor lifts (commonly known as scissor lifts) to prevent accidents and ensure the safety of operators and surrounding personnel.

[0003] With the acceleration of urbanization, old residential communities in my country are facing many problems, such as aging buildings, inadequate facilities, and dirty and disorderly environment. These problems not only affect the quality of life of residents, but also restrict the sustainable development of cities. Therefore, the renovation of old residential communities has become one of the important tasks of urban renewal. The main equipment used for the renovation of old residential communities is the scissor lift for exterior wall decoration and upgrading of residential buildings with 3 floors or less.

[0004] Chinese patent CN223804855U discloses a safety lifting platform for high-altitude cleaning, including a lifting scissor lift: a guardrail is fixedly installed on the top of the lifting scissor lift, a horizontal plate is welded to the surface of the guardrail, an operating platform is set on the outer side of the horizontal plate, a motor and a limiting block are fixedly installed on the surface of the horizontal plate by bolts, a sliding block is slidably connected to the surface of the limiting block, and a rack is integrally formed on the surface of the sliding block; the patent uses a motor to drive a gear to rotate, which in turn drives a U-shaped rod to move vertically through the rack, and then the U-shaped rod, through the cooperation of a rectangular sleeve block and an L-shaped insert block, drives the operating platform to adjust its height, thereby achieving adjustment of the relative height of the operating platform on the platform, so that the actual height of the operating platform can be adapted to the use of cleaning personnel of different heights, thus improving the applicability and ease of use of the safety lifting platform.

[0005] However, the above-mentioned patents have the following shortcomings: the existing scissor lifts are prone to shaking when working at heights, and workers' negligence can easily lead to safety accidents. They do not address the stable connection between the scissor lift and the wall during operation, so the scissor lift still has the risk of shaking. They also do not provide a height measurement and marking function, so operators cannot intuitively know the current working height.

[0006] Therefore, the present invention provides a safety auxiliary device for scissor carts. Summary of the Invention

[0007] The purpose of this invention is to provide a safety auxiliary device for scissor carts to solve the problems mentioned in the background art.

[0008] The technical solution adopted by the present invention to solve its technical problem is: a scissor cart safety auxiliary device, including a scissor cart body and a wall, and also including two sets of safety auxiliary mechanisms;

[0009] Two sets of safety auxiliary mechanisms are disposed between the scissor cart body and the wall. The safety auxiliary mechanism includes a support component disposed on the scissor cart body, an extension component disposed on the support component, a strong suction cup disposed on the extension component to adhere to the wall, a winding component disposed on the support component, and a marking component and a snap-fit ​​component disposed on the winding component.

[0010] Furthermore, the support assembly includes a fixed sliding sleeve fixedly mounted on the scissor cart body, a sliding rod fixedly mounted on the fixed sliding sleeve, a handle and a support block fixedly mounted on the sliding rod, and a first protective shell fixedly mounted on the support block.

[0011] Furthermore, the extension assembly includes an extension sleeve slidably mounted on a slide rod, the extension sleeve being fixed to a powerful suction cup, the extension sleeve being slidably connected to a first protective housing, and a threaded block being fixedly mounted on the extension sleeve.

[0012] Furthermore, a rotating handle is rotatably mounted on the support block, and a threaded rod that is threadedly connected to the threaded block is fixedly mounted on the rotating handle.

[0013] Furthermore, the powerful suction cup is equipped with a digital display switch.

[0014] Furthermore, the winding assembly includes a limiting shell fixedly mounted on the first protective housing, a winding shaft rotatably mounted on the limiting shell, and a crank handle fixedly mounted on the winding shaft.

[0015] Furthermore, the marking assembly includes a marking rope wound on a take-up spool, with lead blocks tied to the ends of the marking rope.

[0016] Furthermore, a marking line is set on the marking rope at one-meter intervals.

[0017] Furthermore, the snap-fit ​​assembly includes a second protective outer shell fixedly mounted on the limiting shell, a rotating block fixedly mounted on the crank handle that fits against the inner wall of the second protective outer shell, a plurality of slots being provided on the rotating block, a side shell fixedly mounted on the limiting shell, a first spring connected to the inner wall of the side shell, a sliding plate slidably connected to the end of the first spring, and a snap-fit ​​plate fixedly mounted on the sliding plate that snaps into the slots and is slidably connected to the side shell.

[0018] Furthermore, a pull handle that is slidably connected to the side shell is fixedly installed on the slide plate, a limit block is fixedly installed on the pull handle, a fixed shell is fixedly installed on the limit shell, and two second springs are connected to the inner wall of the fixed shell. The ends of the two second springs are connected to a locking block that is adapted to the limit block.

[0019] The beneficial effects of this invention are:

[0020] (1) The present invention fixes the fixed sliding sleeve on the scissor cart body, so that the fixed sliding sleeve supports the powerful suction cup through the sliding rod and the extension sleeve. By adsorbing the powerful suction cup onto the wall, the powerful suction cup can use the wall to provide stable support for the scissor cart body. By setting a digital display switch on the powerful suction cup, the safety of the scissor cart body operation can be improved.

[0021] (2) By rotating the handle, the present invention can drive the threaded rod to rotate, and the threaded rod can drive the extension sleeve to move by the thread action with the threaded block. The extension sleeve can drive the powerful suction cup to move along the slide rod, and the powerful suction cup can move to fit against the wall and be tightly adsorbed. Thus, the position of the powerful suction cup can be adjusted to compensate for the distance between the scissor car body and the wall.

[0022] (3) By pulling the handle upward, the handle moves the card plate upward through the slide plate, so that the card plate moves away from the rotating block and no longer fixes the rotating block. The handle moves the limiting block upward, so that the limiting block squeezes the card block into the inner side of the fixed shell, so that the limiting block can move to the top of the card block, so that the card block blocks the limiting block under the support of the second spring. By turning the handle, the winding shaft is rotated, so that the winding shaft can wind up and unwind the marking rope, so that the lead block can move to the ground. By pressing the handle downward, the limiting block can move to the bottom of the card block, so that the card plate can be locked in the appropriate position of the slot on the rotating block under the elastic support of the first spring. This allows the workers to know the height of the person carried by the scissor cart according to the marking line on the marking rope, so as to assist in high-altitude operations.

[0032] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0033] like Figures 1-7 As shown, the scissor cart safety auxiliary device of the present invention includes a scissor cart body 29 and a wall 30, and also includes two sets of safety auxiliary mechanisms; the two sets of safety auxiliary mechanisms are disposed between the scissor cart body 29 and the wall 30. Each safety auxiliary mechanism includes a support component disposed on the scissor cart body 29, an extension component disposed on the support component, a strong suction cup 1 for adsorbing the wall 30 disposed on the extension component, a winding component disposed on the support component, a marking component and a snap-fit ​​component disposed on the winding component, and the support component being fixedly installed on the scissor cart body 29. A fixed sliding sleeve 6 is provided, on which a sliding rod 4 is fixedly installed. A grip 5 and a support block 7 are fixedly installed on the sliding rod 4. A first protective shell 11 is fixedly installed on the support block 7. An extension assembly includes an extension sleeve 3 that is slidably installed on the sliding rod 4. The extension sleeve 3 is fixed to the powerful suction cup 1. The extension sleeve 3 is slidably connected to the first protective shell 11. A threaded block 10 is fixedly installed on the extension sleeve 3. A rotating handle 8 is rotatably installed on the support block 7. A threaded rod 9 that is threadedly connected to the threaded block 10 is fixedly installed on the rotating handle 8. A digital display switch 2 is provided on the powerful suction cup 1.

[0034] Specifically, by fixing the fixed sliding sleeve 6 to the scissor cart body 29, the fixed sliding sleeve 6 supports the powerful suction cup 1 through the sliding rod 4 and the extension sleeve 3. By adsorbing the powerful suction cup 1 onto the wall 30, the powerful suction cup 1 can use the wall 30 to provide stable support for the scissor cart body 29. By setting a digital display switch 2 on the powerful suction cup 1, the digital display switch 2 adopts a miniature pressure sensor and an LCD screen to display the negative pressure value inside the powerful suction cup 1 in real time, and issue an alarm when the pressure is insufficient, ensuring the reliability of adsorption, thereby improving the safety of the scissor cart body 29 operation.

[0035] By rotating the handle 8, the threaded rod 9 can be rotated, and the threaded rod 9 can move the extension sleeve 3 by using the thread action with the threaded block 10. The extension sleeve 3 can move the powerful suction cup 1 along the slide rod 4, so that the powerful suction cup 1 can move to fit against the wall 30 and be tightly adhered. In this way, the position of the powerful suction cup 1 can be adjusted to compensate for the distance between the scissor cart body 29 and the wall 30.

[0036] In this embodiment, the winding assembly includes a limiting shell 12 fixedly mounted on the first protective shell 11, a winding shaft 13 rotatably mounted on the limiting shell 12, and a crank handle 14 fixedly mounted on the winding shaft 13. The marking assembly includes a marking rope 15 wound on the winding shaft 13, with lead blocks 16 tied to the ends of the marking rope 15, and marking lines set at intervals of one meter on the marking rope 15. The snap-fit ​​assembly includes a second protective shell 17 fixedly mounted on the limiting shell 12, and a rotating block 18 fixedly mounted on the crank handle 14, which fits against the inner wall of the second protective shell 17. The rotating block 18 has multiple slots 19. A side shell 20 is fixedly installed. A first spring 21 is connected to the inner wall of the side shell 20. The end of the first spring 21 is connected to a slide plate 22 that is slidably connected to the side shell 20. A card plate 23 that engages with the card slot 19 is fixedly installed on the slide plate 22 and is slidably connected to the side shell 20. A pull handle 24 that is slidably connected to the side shell 20 is fixedly installed on the slide plate 22. A limit block 25 is fixedly installed on the pull handle 24. A fixed shell 26 is fixedly installed on the limit shell 12. Two second springs 27 are connected to the inner wall of the fixed shell 26. The ends of the two second springs 27 are connected to a card block 28 that is adapted to the limit block 25.

[0037] Specifically, by pulling the handle 24 upwards, the handle 24 moves the locking plate 23 upwards via the slide plate 22, causing the locking plate 23 to move away from the rotating block 18 and no longer fix the rotating block 18. The handle 24 then moves the limiting block 25 upwards, causing the limiting block 25 to press the locking block 28 into the inner side of the fixing shell 26. This allows the limiting block 25 to move to the top of the locking block 28, where the locking block 28, supported by the second spring 27, blocks the limiting block 25. By rotating the handle 14, the locking plate 23 moves upwards. The rewind shaft 13 rotates to rewind and unwind the marking rope 15, allowing the lead block 16 to move to the ground. By pressing down the pull handle 24, the limiting block 25 can move to the bottom of the locking block 28, allowing the locking plate 23 to engage with the appropriate slot 19 on the rotating block 18 under the elastic support of the first spring 21. This allows workers to determine the height of the person carried by the scissor cart 29 based on the marking lines on the marking rope 15, thus assisting in high-altitude operations.

[0038] Working principle: By fixing the fixed sliding sleeve 6 to the scissor cart body 29, the fixed sliding sleeve 6 supports the powerful suction cup 1 through the sliding rod 4 and the extension sleeve 3. By rotating the handle 8, the handle 8 can drive the threaded rod 9 to rotate, so that the threaded rod 9 can drive the extension sleeve 3 to move through the threaded action with the threaded block 10. The extension sleeve 3 can drive the powerful suction cup 1 to move along the sliding rod 4, so that the powerful suction cup 1 can move to fit against the wall 30 and be tightly attached. Thus, the position of the powerful suction cup 1 can be adjusted to compensate for the distance between the scissor cart body 29 and the wall 30. By attaching the powerful suction cup 1 to the wall 30, the powerful suction cup 1 can use the wall 30 to provide stable support for the scissor cart body 29.

[0039] By pulling the handle 24 upwards, the handle 24 moves the clamping plate 23 upwards via the slide plate 22, causing the clamping plate 23 to move away from the rotating block 18 and no longer fix it. The handle 24 then moves the limiting block 25 upwards, causing the limiting block 25 to press the clamping block 28 into the inner side of the fixing shell 26. This allows the limiting block 25 to move to the top of the clamping block 28, where the clamping block 28, supported by the second spring 27, blocks the limiting block 25. Rotating the rocker handle 14 then drives the winding process. The shaft 13 rotates, allowing the winding shaft 13 to wind up and unwind the marking rope 15, enabling the lead block 16 to move to the ground. By pressing down the pull handle 24, the limiting block 25 can move to the bottom of the locking block 28, allowing the locking plate 23 to engage with the inner side of the appropriate slot 19 on the rotating block 18 under the elastic support of the first spring 21. This allows the workers to determine the height of the person carried by the scissor cart 29 based on the marking lines on the marking rope 15, thus assisting in high-altitude operations.
