Description

Technical Field

[0001] This utility model relates to the field of high-altitude work equipment technology, and in particular to a protective device for a suspended platform used in building exterior wall construction. Background Technology

[0002] Aerial work platforms refer to various types of equipment used to support personnel or tools to work at a certain height (usually 2 meters or more) above the ground. They can achieve vertical or horizontal movement, ensuring the safety and efficiency of high-altitude operations. They encompass various types, such as construction scaffolding, aerial work vehicles, scaffolding, and elevators, and are widely used in construction, power maintenance, and municipal engineering. Their core function is to provide a stable working platform equipped with protective devices to reduce the risks of falls from heights and being struck by objects, meeting the needs of different heights, sites, and operations.

[0003] When carrying out high-altitude operations, construction scaffolds are often used. Existing construction scaffolds mostly use opening and closing doors for workers to go up and down. However, these doors are usually connected and fixed to the guardrails by latches or chains, which poses safety risks and is also cumbersome to open and close, greatly affecting work efficiency. Furthermore, when working at heights, the existing equipment is prone to swaying when the wind is strong, which poses a significant danger.

[0004] Therefore, we propose a protective device for suspended scaffolds used in building exterior wall construction to solve the above problems. Utility Model Content

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A protective device for a suspended platform used in building exterior wall construction includes a stable base, a construction platform fixedly installed on the inner side of the stable base, a fixed protective plate fixedly installed on the top of the construction platform, an opening and closing door rotatably installed at the notch of the fixed protective plate, and a sliding groove provided at the bottom of the opening and closing door; two spherical bases are fixedly installed on one side of the stable base, each of the two spherical bases has a spherical groove on one side, a spherical head is rotatably installed on the inner side of each of the two spherical grooves, an adsorption groove is provided on one side of each of the two spherical heads, and a suction cup is fixedly installed on the inner side of each of the two adsorption grooves.

[0009] Specifically, a fixed protective railing is fixedly installed on the top of the fixed protective plate, and an opening and closing protective railing is fixedly installed on the top of the opening and closing door.

[0011] Specifically, a vacuum pump is fixedly installed on the inner wall of one side of each of the two adsorption tanks to facilitate the removal of gas between the suction cup and the wall.

[0012] Specifically, an inflatable buffer pad is fixedly installed on the inner side of the stabilizing base, and a miniature pressure relief valve is provided on the top of the inflatable buffer pad, which can be used to slowly release air.

[0013] Specifically, multiple high-pressure gas cylinders are detachably installed at the bottom of the construction platform. Connecting pipes and pressure sensors are fixedly installed at the bottom of the construction platform. The output heads of the multiple high-pressure gas cylinders are connected to the same connecting pipe. An electrically controlled gas valve is fixedly installed at one end of the connecting pipe, and the other end of the electrically controlled gas valve is connected to the air inlet flange of the inflatable buffer pad, which facilitates the control of the high-pressure gas cylinders to quickly inflate the inflatable buffer pad.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: the threaded rod and threaded sleeve can drive the limiting post to move down into the fixing groove to complete the limiting of the opening and closing door. It is no longer necessary for workers to manually fix it with pins or chains, which improves work efficiency and increases the stability of the opening and closing door. In addition, the suction cup and vacuum pump can make the construction basket fit against the wall when working at height, which increases the stability and safety of working at height.

[0021] Reference Figure 1-5 A protective device for a suspended platform during construction of an exterior wall includes a stable base 1, a construction platform 2 fixedly installed on the inner side of the stable base 1, a fixed protective plate 4 fixedly installed on the top of the construction platform 2, an opening and closing door 6 rotatably installed at the notch of the fixed protective plate 4, and a sliding groove provided at the bottom of the opening and closing door 6; two spherical bases 13 fixedly installed on one side of the stable base 1, each of the two spherical bases 13 having a spherical groove on one side, a spherical head 14 rotatably installed on the inner side of each of the two spherical grooves, an adsorption groove on one side of each of the two spherical heads 14, and a suction cup 16 fixedly installed on the inner side of each of the two adsorption grooves.

[0022] In this embodiment, a blocking metal strip 3 is fixedly installed on the top of the construction platform 2, a fixing groove 12 is opened on the top of the construction platform 2, and a rubber pad is provided on the top of the construction platform 2.

[0023] In this embodiment, a threaded rod 9 is rotatably installed on the top inner wall of the sliding groove, and a threaded sleeve 10 is slidably installed on the inner side of the sliding groove. The threaded sleeve 10 is threadedly connected to the threaded rod 9, and a limit post 11 is fixedly installed at the bottom end of the threaded sleeve 10. The limit post 11 is adapted to the fixed groove 12 to facilitate the fixed and limited opening and closing door 6.

[0024] In this embodiment, a fixed protective railing 5 is fixedly installed on the top of the fixed protective plate 4, and an opening and closing protective railing 7 is fixedly installed on the top of the opening and closing door 6.

[0025] In this embodiment, a motor slot is provided inside the opening and closing door 6. A servo motor 8 is fixedly installed on the inner wall of one side of the motor slot. The output shaft of the servo motor 8 is fixedly connected to the threaded rod 9. The servo motor 8 can drive the threaded rod 9 to rotate.

[0026] In this embodiment, a vacuum pump 15 is fixedly installed on the inner wall of one side of each of the two adsorption tanks to facilitate the removal of gas between the suction cup 16 and the wall.

[0027] In this embodiment, an inflatable buffer pad 17 is fixedly installed on the inner side of the stabilizing base 1. The top of the inflatable buffer pad 17 is provided with a micro pressure relief valve, which can be used to slowly release air.

[0028] In this embodiment, multiple high-pressure gas cylinders 18 are detachably installed at the bottom of the construction platform 2. A connecting pipe 19 and a pressure sensor 21 are fixedly installed at the bottom of the construction platform 2. The output heads of the multiple high-pressure gas cylinders 18 are connected to the same connecting pipe 19. An electrically controlled gas valve 20 is fixedly installed at one end of the connecting pipe 19. The other end of the electrically controlled gas valve 20 is connected to the air inlet flange of the inflatable buffer pad 17, which facilitates the control of the high-pressure gas cylinders 18 to quickly inflate the inflatable buffer pad 17.

[0029] Working Principle: During high-altitude operations, after the worker ascends to the construction platform 2, they close the opening / closing door 6. Then, the servo motor 8 is activated, driving the threaded rod 9 to rotate. A threaded sleeve 10 is fitted onto the outer thread of the threaded rod 9, slidingly mounted inside the sliding groove. Therefore, the threaded rod 9 cannot drive the threaded sleeve 10 to rotate. The rotation of the threaded rod 9 causes the threaded sleeve 10 to move axially, thereby moving the limiting post 11. The limiting post 11 moves downwards and engages in the fixing groove 12, completing the limiting and fixing of the opening / closing door 6. The construction basket then rises. When it reaches the construction height, the worker controls the construction basket to approach the wall, ensuring the two suction cups 16 are in contact with the wall. Then, two vacuum pumps 1 are activated. 5. Two vacuum pumps 15 remove the air between the corresponding suction cups 16 and the wall, thereby enhancing the stability of the construction scaffold during high-altitude operations. In case of an emergency, the construction scaffold falls rapidly. The pressure sensor 21 detects a sudden decrease in the load on the bottom of the scaffold (indicating a fall) and immediately triggers an inflation command, controlling the opening of the electronically controlled gas valve 20. Compressed gas from multiple high-pressure gas cylinders 18 is quickly injected into the air chamber of the inflatable buffer pad 17 through the connecting pipe 19. When the inflatable buffer pad 17 contacts the ground, the air chamber absorbs the impact energy through deformation, the outer fabric disperses the impact force, and the inner gas is slowly vented (the inflatable buffer pad 17 itself has a miniature pressure relief valve to control the venting speed), thus achieving a "soft landing".

[0030] The technological advancement of this utility model compared to the prior art is that it can drive the limiting post 11 to move down into the fixing groove 12, thereby limiting the opening and closing door 6. This eliminates the need for workers to manually fix it with pins or chains, improving work efficiency and increasing the stability of the opening and closing door 6. Furthermore, the suction cup 16 and vacuum pump 15 can be used to make the construction basket fit against the wall during high-altitude operations, increasing the stability and safety of high-altitude operations.
