Technical Field

[0001] The utility model relates to the technical field of lifting equipment, in particular to a lift bracket which is easy to fold. Background Art

[0002] In most industries and workplaces, safety standards and regulations require that lifts be adequately supported when in use. These regulations are designed to protect the lives of operators and workplace safety. Using supports ensures that lifts are installed and used in compliance with relevant safety requirements, avoiding legal liability and safety risks associated with non-compliance. Worksite floor conditions are often complex and varied, and may be uneven.

[0003] Lift stands typically feature adjustable legs or specialized bottom structures to accommodate uneven surfaces. By adjusting the length or angle of the legs, the lift can remain level on slopes, potholes, and other uneven surfaces, ensuring safe and normal lifting operations. This adaptability is crucial, for example, at outdoor construction sites or in warehouses with inaccurately leveled floors.

[0004] After searching, the Chinese patent number CN208932891U discloses a foldable lift, including a base, a top plate, a bracket and a hydraulic rod. The top plate is fixedly connected to the top of the base through the bracket, and both ends of the hydraulic rod are rotatably connected to the bracket. The top of the top plate is respectively provided with a guardrail, a pulley, an anti-slip pad and a servo motor. The guardrail is rotatably connected to the top plate and the surface of the guardrail is fixedly connected to the LED light strip. The bottom end of the top plate is fixedly connected to the protective cover, and a solar panel and a battery are respectively provided inside the protective cover. The solar panel is slidably connected to the top plate through a slide rail, and the top plate and the side walls of the base are welded with universal wheels. This patent is to provide a foldable lift to alleviate the technical problems in the prior art of existing outdoor decoration lifts, which are not convenient to fold, occupy a large space after use, and are not convenient to transport.

[0005] During the use of the above-mentioned device, when facing uneven ground, the elevator may shake because the bottom of the elevator moves on rollers. In addition, the current elevator guardrail is fixed, which may cause construction inconvenience. Therefore, a foldable elevator bracket is proposed. Summary of the Invention

[0006] The purpose of the utility model is to solve the shortcomings in the prior art, that is, when facing uneven ground, the elevator may shake because the bottom of the elevator moves on rollers, and the current elevator guardrail is fixed, which may cause construction inconvenience, and to propose a foldable elevator bracket.

[0007] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0008] A foldable lift bracket comprises a base, a second motor is fixedly connected to the top of the base, the second motor is fixedly connected to a propulsion threaded column, a first fixing block and a second fixing block are respectively threadedly connected to the periphery of the propulsion threaded column, the propulsion threaded column is threadedly connected to an embedded threaded block, the embedded threaded block is fixedly connected to a stabilizing rod, two sets of second cross rods are provided on both sides of the stabilizing rod, and the second cross rods are rotatably connected to a pedal;

[0009] The second cross rod is rotatably connected to the first cross rod, the first cross rod is slidably connected to the pedal, a sliding mechanism is provided on the side of the pedal, the sliding mechanism is used to adjust the height of the guardrail frame, a first motor is provided inside the base, the first motor is fixedly connected to the first worm, the first worm is meshedly connected to the first worm wheel, a support block is rotatably connected below the first worm wheel, and the first worm wheel is threadedly connected to a lifting threaded column.

[0010] The above technical solution further includes:

[0011] The sliding mechanism includes a guardrail frame arranged on the side of the first cross rod, the guardrail frame is fixedly connected to a rack, the rack is meshed with a gear, the gear is fixedly connected to a second worm gear, the second worm gear is meshed with a second worm, the second worm gear is rotatably connected to the first cross rod, the side of the first cross rod is fixedly connected to a motor block, and the motor block is meshed with the second worm.

[0012] The side surface of the lifting threaded column is threadedly connected to a base, the support block is fixed inside the base, and the bottom of the base is provided with a redundant pulley for movement.

[0013] The first fixing block is fixed above the base, the second fixing block is also fixed above the base, and the stabilizing rod is rotatably connected to a second cross rod.

[0014] Redundant lifting threaded columns for supporting the base are arranged around the base, and the first cross rod is rotatably connected to the protrusion above the base.

[0015] The utility model has the following beneficial effects:

[0016] In the utility model, the lift bracket can effectively cope with various uneven ground conditions through a unique adjustable support structure. When encountering uneven terrain, the multiple sets of lifting threaded columns at the bottom of the base can be adjusted to slide downward along the threads inside the first worm gear, thereby achieving stable support for the base.

[0017] During construction, the motor block is controlled to rotate, driving the second worm to mesh with the second worm wheel, which in turn causes the gear fixed to the side of the second worm wheel to mesh with the rack. This allows the guardrail to slide up and down along the side of the first crossbar, adjusting the guardrail to the appropriate safe construction height. This adjustable guardrail design greatly improves the convenience and flexibility of construction, allowing workers to operate more freely during construction without being restricted by fixed guardrails.

[0018] After construction is complete, the second motor rotates the propulsion screw inside the first and second fixing blocks, allowing the step to fold smoothly using the threads within the first and second fixing blocks. The propulsion screw drives the embedded threaded blocks to further ensure that the bottom of the step fits tightly against the top of the second fixing block, achieving efficient folding. This folding design not only facilitates storage and transportation of the lift when not in operation, but also improves the device's portability and operability. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] See also Figure 1-Figure 5 As shown, the utility model is a foldable lift bracket, comprising a base 1, a second motor 6 is fixedly connected to the top of the base 1, the second motor 6 is fixedly connected to a propulsion threaded column 7, the periphery of the propulsion threaded column 7 is respectively threadedly connected to a first fixing block 8 and a second fixing block 9, the propulsion threaded column 7 is threadedly connected to an embedded threaded block 13, the embedded threaded block 13 is fixedly connected to a stabilizing rod 14, two sets of second cross rods 12 are provided on both sides of the stabilizing rod 14, and the second cross rods 12 are rotatably connected to a pedal 15;

[0027] The second cross rod 12 is rotatably connected to the first cross rod 10, and the first cross rod 10 is slidably connected to the pedal 15. A sliding mechanism is provided on the side of the pedal 15, and the sliding mechanism is used to adjust the height of the guardrail frame 16. A first motor 5 is provided inside the base 1, and the first motor 5 is fixedly connected to the first worm 3. The first worm 3 is meshedly connected to the first worm gear 11, and the support block 4 is rotatably connected below the first worm gear 11. The first worm gear 11 is threadedly connected to the lifting threaded column 2.

[0028] In one embodiment, for the sliding mechanism, the sliding mechanism includes a guardrail frame 16 arranged on the side of the first cross rod 10, the guardrail frame 16 is fixedly connected to the rack 17, the rack 17 is meshedly connected to the gear 18, the gear 18 is fixedly connected to the second worm gear 20, the second worm gear 20 is meshedly connected to the second worm 21, the second worm gear 20 is rotatably connected to the first cross rod 10, and the side of the first cross rod 10 is fixedly connected to the motor block 19, and the motor block 19 is meshedly connected to the second worm 21.

[0029] In this embodiment, the guardrail frame 16 is provided to slide up and down, so that when the elevator moves up and down, it is convenient to adapt to two different modes of work and safety. When working, the second worm gear 20 is used to rotate the drive gear 18 to further drive the guardrail frame 16 to move up and down, which is convenient for adapting to the height when working and does not hinder construction. When it needs to rise or fall, it rises to prevent workers from falling and getting injured due to not standing firmly.

[0030] In one embodiment, for the lifting threaded column 2, the side surface of the lifting threaded column 2 is threadedly connected to the base 1, the support block 4 is fixed inside the base 1, and the bottom of the base 1 is provided with a redundant pulley 22 for movement.

[0031] In one embodiment, the first fixing block 8 is fixed above the base 1 , the second fixing block 9 is also fixed above the base 1 , and the stabilizing rod 14 is rotatably connected to the second cross rod 12 .

[0032] In this embodiment, the two cross rods facilitate stable lifting and lowering. By setting a propulsion thread column, it is to prevent the propulsion thread column 7 from rotating when the motor is damaged and the motor cannot rotate, thereby preventing the elevator from falling rapidly.

[0033] In one embodiment, for the base 1 , redundant lifting threaded columns 2 for supporting the base 1 are provided around the base 1 , and the first cross rod 10 is rotatably connected to the protrusion above the base 1 .

[0034] The working principle of a foldable elevator bracket in the present invention is that, first, during construction, the elevator is transferred to a suitable position through the pulley 22 for lifting, and then the first worm 3 is driven to rotate by the first motor 5, and then the lifting thread column 2 is engaged with the first worm 3, so that the lifting thread column 2 is rotated above the support block 4, and then the lifting thread column 2 is rotated up and down with the base 1, and the lifting thread column 2 is rotated with the first worm wheel 11, so that the lifting thread column 2 is threaded and slides downward.

[0035] When facing uneven terrain, the multiple sets of lifting threaded columns 2 set at the bottom of the base 1 can be adjusted to slide downward along the threads inside the first worm gear 11 together with other first worm gears 11, so that the base 1 can be stably supported. When the staff is performing construction, they stand inside the guardrail frame 16, and then control the motor block 19 to rotate to further drive the second worm 21 to engage with the second worm gear 20. The gear 18 fixed on the side of the second worm gear 20 will engage with the rack 17 to make the guardrail frame 16 slide up and down on the side of the first cross rod 10. During the lifting period, the guardrail frame 16 is used to ensure the safety of the staff when moving up and down. When working, the motor block 19 is adjusted to adjust the guardrail frame 16 to a height where construction can be done safely.

[0036] After the construction is completed, the rotation of the second motor 6 further drives the propulsion threaded column 7 to rotate inside the first fixed block 8 and the second fixed block 9. The internal threads of the first fixed block 8 and the second fixed block 9 can ensure that the pedal 15 is folded up. The propulsion threaded column 7 drives the embedded threaded block 13 to further ensure that the bottom of the pedal 15 can fit tightly against the top of the second fixed block 9, thereby achieving folding.

[0037] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
