[0003] An existing mobile aerial work platform for construction (Announcement No.: CN208784130U) has at least the following drawbacks: the guardrail on the top of the control platform is fixed on three sides, which protects the personal safety of the workers, but obstructs the workers' side construction. In addition, the height of the device is limited, which is not conducive to the height adjustment of the aerial work platform. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a multi-functional anti-fall construction platform for high-altitude operations.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A multi-functional construction platform for fall prevention includes a lifting platform, side railings, and stop bars. The side railings are located on top of the lifting platform and include a first railing and a second railing. A sliding seat is fixedly connected to one side of the bottom of both the first and second railings. Several sliding grooves are formed at diagonal corners of the top of the lifting platform, and the sliding seats are rotatably connected inside the sliding grooves. Positioning valves are provided on the side of both the first and second railings away from the sliding seats. Several positioning valves pass through the bottom plates of the first and second railings and are threaded to the top of the lifting platform. Positioning grooves are formed on the top of both the first and second railings. Both ends of the stop bars are inserted into the positioning grooves, and one end of the stop bar is fixedly connected to the second railing via a positioning valve. A sliding groove is formed on the side of the first railing away from the positioning groove.

[0007] As a further embodiment of this utility model, a third guardrail is provided on the side of the side guardrail away from the stop bar. A handle is fixedly connected to the top of the stop bar. The third guardrail is located on the top of the lifting platform. The third guardrail includes an extension plate, a railing, a slide block, and a valve bolt. The top of the railing is fixedly connected to the bottom of the extension plate. The slide block is fixedly connected to the bottom of the extension plate. The slide block is rotatably connected inside the slide groove.

[0008] As a further embodiment of this utility model, the extension plate is rotatably connected to the top of the first guardrail via a sliding block, the valve bolt passes through the extension plate and is threadedly connected to the top of the second guardrail, the bottom of the railing is attached to the top of the lifting platform, the sliding block and the valve bolt are respectively located at opposite corners of the extension plate, and a first set of drive telescopic columns and a second set of drive telescopic columns are respectively fixedly connected to the four corners of the bottom of the lifting platform.

[0009] As a further embodiment of this utility model, a ladder is provided between the first group of drive telescopic columns, and a shaft is fixedly connected through the top of the ladder. One end of the shaft is rotatably connected to the inner side of the top of the first group of drive telescopic columns, and a drive motor is fixedly connected to the other end of the shaft. The drive motor is fixedly connected to the inner side of the other top of the first group of drive telescopic columns.

[0010] As a further embodiment of this utility model, a handrail is fixedly connected to the outside of the ladder, a base is provided at the bottom of the lifting platform, the bottom end of the ladder is slidably connected to the top of the base, a remote control box is fixedly connected to the side of the first set of drive telescopic columns near the second set of drive telescopic columns, and the bottom ends of the first set of drive telescopic columns and the second set of drive telescopic columns are both fixedly connected to the top of the base.

[0011] As a further embodiment of this utility model, several drive cylinders are provided on both sides of the ladder. The bottom of the drive cylinder is fixedly connected to the inside of the base. The telescopic end of the drive cylinder passes through the base and is fixedly connected to a support. Several casters are provided on one side of the support, and the casters are fixedly connected to the bottom of the base.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. When construction workers need to perform side work, they raise the stop bar to separate it from the positioning groove. Then, they rotate the positioning valve at the bottom of the first guardrail, causing it to move out of the first guardrail and release the positioning of one side of the bottom of the first guardrail from the lifting platform. The first guardrail rotates outward 270°, and the sliding seat on one side of the bottom of the first guardrail drives it to rotate, overlapping the first guardrail outside the third guardrail, thus opening the side of the lifting platform. The construction workers then insert one end of the stop bar into the positioning groove of the second guardrail and use the positioning valve to fix the stop bar in place, blocking the entrance and exit of the lifting platform. The opening method of the second guardrail is the same as that of the first guardrail. After the second guardrail is released from its positioning connection, it rotates outward 270° to the outside of the entrance and exit of the lifting platform, facilitating side work for the construction workers and preventing the guardrail from obstructing their side work. At the same time, the guardrail also ensures the personal safety of the construction workers.

[0014] 2. Construction workers enter the lifting platform via a ladder. Based on the building's construction height, the first and second sets of drive telescopic columns are simultaneously activated. The telescopic ends of these columns push the lifting platform and the workers upwards, facilitating high-altitude operations. To allow other workers to access the lifting platform, the workers can adjust the height of the first and second sets of drive telescopic columns and then activate the drive motor. The drive motor rotates the shaft, which in turn adjusts the angle of the ladder, allowing it to follow the lifting platform's ascent and descent, thus facilitating access for other workers.

[0025] Reference Figures 1-6 A multi-functional construction platform for fall prevention includes a lifting platform 1, side railings 2, and guardrails 4. The side railings 2 are located at the top of the lifting platform 1 and include a first railing 201 and a second railing 202. Sliding seats 203 are fixedly connected to one side of the bottom of both the first railing 201 and the second railing 202. Several sliding grooves 101 are formed at the diagonal corners of the top of the lifting platform 1, and the sliding seats 203 are rotatably connected inside the sliding grooves 101. The first railing 201 and the second railing 202 are located away from each other. A positioning valve 204 is provided on one side of the sliding seat 203. Several positioning valves 204 pass through the bottom plates of the first guardrail 201 and the second guardrail 202 and are threaded to the top of the lifting platform 1. The top of the first guardrail 201 and the second guardrail 202 are provided with positioning grooves 205. Both ends of the stop rod 4 are inserted into the positioning grooves 205. One end of the stop rod 4 is fixedly connected to the second guardrail 202 through the positioning valve 204. A sliding groove 206 is provided on the side of the first guardrail 201 away from the positioning groove 205.

[0026] In use, when construction workers need to perform side construction, they raise the stop bar 4 to separate it from the positioning groove 205, then rotate the positioning valve 204 at the bottom of the first guardrail 201. The positioning valve 204 moves out of the first guardrail 201, releasing the positioning of one side of the bottom of the first guardrail 201 from the lifting platform 1. The first guardrail 201 rotates outward 270°, and the sliding seat 203 on one side of the bottom of the first guardrail 201 drives the first guardrail 201 to rotate. The first guardrail 201 rotates and overlaps outside the third guardrail 3, opening the side of the lifting platform 1 for construction. Workers then insert one end of the stop bar 4 into the positioning groove 205 of the second guardrail 202, and use the positioning valve 204 to fix the stop bar 4 in the positioning groove 205 to block the entrance and exit of the lifting platform 1. The opening method of the second guardrail 202 is the same as that of the first guardrail 201. After the positioning connection of the second guardrail 202 is released, it rotates outward 270° to the outside of the entrance and exit of the lifting platform 1, which facilitates side construction by construction personnel and avoids the guardrail from obstructing the side construction of construction personnel. At the same time, the guardrail also ensures the personal safety of construction personnel.

[0027] In this embodiment, a third guardrail 3 is provided on the side of the side guardrail 2 away from the stop bar 4. A handle 401 is fixedly connected to the top of the stop bar 4. The third guardrail 3 is located on the top of the lifting platform 1. The third guardrail 3 includes an extension plate 301, a railing 302, a slide block 303, and a valve bolt 304. The top of the railing 302 is fixedly connected to the bottom of the extension plate 301, and the slide block 303 is fixedly connected to the bottom of the extension plate 301. The slide block 303 is rotatably connected inside the slide groove 206.

[0028] When in use, after the construction personnel enter the lifting platform 1, they can hang the handle 401 on the stop bar 4 on the side guardrail 2 for easy storage and placement of the stop bar 4, and avoid the stop bar 4 being placed on the lifting platform 1 and affecting the movement of the construction personnel. The extension plate 301 of the third guardrail 3 is twice as wide as the top plate of the first guardrail 201. The slide 303 drives the third guardrail 3 to rotate 270°, so that the extension plate 301 of the third guardrail 3 overlaps the top of the first guardrail 201. At the same time, the workers rotate the valve 304, and the valve 304 rotates down and moves into the top of the stop bar 4 to fix the position of the overlapping third guardrail 3, so as to prevent the third guardrail 3 from swinging after being opened and affecting the construction personnel to carry out high-altitude operations.

[0029] In this embodiment, the extension plate 301 is rotatably connected to the top of the first guardrail 201 via the slide block 303, the valve bolt 304 passes through the extension plate 301 and is threadedly connected to the top of the second guardrail 202, the bottom of the railing 302 is attached to the top of the lifting platform 1, the slide block 303 and the valve bolt 304 are located at opposite corners of the extension plate 301, and the first set of drive telescopic columns 5 and the second set of drive telescopic columns 7 are fixedly connected to the four corners of the bottom of the lifting platform 1.

[0030] In use, construction workers take out the drive remote control from the remote control box 502 inside the first set of drive telescopic columns 5, so that they can control the lifting of the first set of drive telescopic columns 5 and the second set of drive telescopic columns 7 after entering the lifting platform 1. Construction workers enter the lifting platform 1 through the ladder 6, and simultaneously start the first set of drive telescopic columns 5 and the second set of drive telescopic columns 7 according to the building construction height. The telescopic column 7 ends of the first set of drive telescopic columns 5 and the second set of drive telescopic columns push the lifting platform 1 and the construction workers to rise, which facilitates the construction workers to carry out high-altitude operations.

[0031] In this embodiment, a ladder 6 is provided between the first group of drive telescopic columns 5. A shaft 602 is fixedly connected through the top of the ladder 6. One end of the shaft 602 is rotatably connected through the inner side of the top of the first group of drive telescopic columns 5. The other end of the shaft 602 is fixedly connected to a drive motor 501. The drive motor 501 is fixedly connected inside the other top of the first group of drive telescopic columns 5.

[0032] In use, to facilitate access to the lifting platform 1 by other construction personnel, the construction personnel adjust the lifting height of the first set of drive telescopic columns 5 and the second set of drive telescopic columns 7, while starting the drive motor 501. The drive motor 501 drives the shaft 602 to rotate, and the shaft 602 drives the ladder 6 to adjust its angle, so that the ladder 6 follows the lifting platform 1 to adjust its tilt angle. The higher the lifting platform 1 is, the smaller the tilt angle of the ladder 6.

[0033] In this embodiment, a handrail 601 is fixedly connected to the outside of the ladder 6, and a base 8 is provided at the bottom of the lifting platform 1. The bottom end of the ladder 6 is slidably connected to the top of the base 8. A remote control box 502 is fixedly connected to the side of the first set of drive telescopic columns 5 near the second set of drive telescopic columns 7. The bottom ends of the first set of drive telescopic columns 5 and the second set of drive telescopic columns 7 are both fixedly connected to the top of the base 8.

[0034] To prevent accidents during the climbing process of the ladder 6, handrails 601 are provided on both sides of the ladder 6 to facilitate the climbing process. They also make it easier for the workers to fasten the safety rope buckles to the handrails 601. The handrails 601 are equipped with dividers to position the safety rope buckles and prevent them from slipping down and affecting the use of the ladder.

[0035] In this embodiment, several drive cylinders 9 are provided on both sides of the ladder 6. The bottom of the drive cylinder 9 is fixedly connected to the inside of the base 8. The telescopic end of the drive cylinder 9 passes through the base 8 and is fixedly connected to a support 901. Several casters 10 are provided on one side of the support 901. The casters 10 are fixedly connected to the bottom of the base 8.

[0036] When in use, the construction workers push the platform, and the casters 10 move the base 8 and its top structure. After the casters 10 stop moving, the workers start the drive cylinder 9. The telescopic end of the drive cylinder 9 moves the support 901 down to the ground, fixing the position of the base 8 and facilitating the use of the platform.

[0037] From the above description, it can be seen that the above embodiments of this utility model achieve the following technical effects: Construction workers climb to the top of the ladder 6, raise the stop bar 4, and the stop bar 4 moves out of the positioning groove 205 of the side guardrail 2. The construction workers enter the lifting platform 1, and then insert both ends of the stop bar 4 into the positioning grooves 205 at the top of the first guardrail 201 and the second guardrail 202 respectively, closing the entrance and exit of the lifting platform 1. When construction workers need to perform side construction, they raise the stop bar 4, separating it from the positioning groove 205, and then rotate the positioning valve 204 at the bottom of the first guardrail 201. The positioning valve 204 moves out of the first guardrail 201, releasing one side of the bottom of the first guardrail 201 from the lifting platform. Positioning of the lifting platform 1: The first guardrail 201 rotates outward 270°. The sliding seat 203 on one side of the bottom of the first guardrail 201 drives the first guardrail 201 to rotate. The first guardrail 201 rotates and overlaps outside the third guardrail 3, opening the side of the lifting platform 1. The construction personnel then insert one end of the stop bar 4 into the positioning groove 205 of the second guardrail 202, and use the positioning valve 204 to fix the stop bar 4 in the positioning groove 205, blocking the entrance and exit of the lifting platform 1. The opening method of the second guardrail 202 is the same as that of the first guardrail 201. After the second guardrail 202 is released from the positioning connection, it rotates outward 270° to the outside of the entrance and exit of the lifting platform 1, facilitating side construction by the construction personnel and avoiding... The absence of guardrails does not obstruct side construction work for workers, while guardrails also ensure their personal safety. Workers retrieve the remote control from the remote control box 502 inside the first set of drive telescopic columns 5, allowing them to control the raising and lowering of the first and second sets of drive telescopic columns 5 and 7 after entering the lifting platform 1. Workers enter the lifting platform 1 via ladder 6 and, based on the construction height, simultaneously activate the first and second sets of drive telescopic columns 5 and 7. The telescopic columns 7 of the first and second sets of drive telescopic columns push the lifting platform 1 and the workers upwards, facilitating high-altitude work. To facilitate access for other workers to the lifting platform 1, [further details are needed]. While personnel adjust the lifting height of the first set of drive telescopic columns 5 and the second set of drive telescopic columns 7, the drive motor 501 is started. The drive motor 501 drives the shaft 602 to rotate, and the shaft 602 drives the ladder 6 to adjust its angle, so that the ladder 6 follows the lifting platform 1 to adjust its tilt angle. The higher the lifting platform 1 is, the smaller the tilt angle of the ladder 6. In order to prevent accidents during the construction personnel's climbing of the ladder 6, handrails 601 are provided on both sides of the ladder 6 to facilitate the construction personnel to climb with the help of the handrails. At the same time, it is also convenient for the construction personnel to fasten the safety rope buckles to the handrails 601. The handrails 601 are equipped with dividers, which have a positioning function for the safety rope buckles and prevent the safety rope buckles from slipping and affecting the use.
