Description
Technical Field
[0001] This utility model relates to the field of construction equipment technology, and in particular to a construction lifting platform. Background Technology
[0002] In modern construction, efficient and safe vertical transportation tools are crucial for improving construction efficiency and ensuring the safety of workers. Small lifting platforms are used on construction sites for operations in confined spaces, detailed finishing work, or frequent handling of small materials. These platforms are typically designed to be foldable or portable, facilitating rapid transfer and installation between different work locations. They primarily achieve their lifting function through hydraulic or electric drive systems and are mainly used for short-distance vertical movement of personnel or lightweight materials.
[0003] However, when it is necessary to frequently hoist tools or goods from the ground to higher places (such as exterior wall repairs and installation work on high-rise buildings), the platform needs to be repeatedly raised and lowered to facilitate workers' access to the goods, resulting in low construction efficiency. Alternatively, workers may need to temporarily set up hoisting ropes on the construction platform to hoist tools and goods, which not only increases the complexity of the operation but also poses safety hazards due to the temporary hoisting ropes.

[0013] Furthermore, the support plate has a pad for abutting against the ground on the side facing the ground.
[0014] Furthermore, the second lifting mechanism is a screw jack, comprising a housing, a screw rotatably disposed within the housing, a worm gear coaxially connected to the screw, a worm meshing with the worm gear, and a nut screwed onto the screw; the housing is disposed at the bottom of the support base, the nut is disposed on the movable base, and the screw can pass through the movable base; when the worm is driven to rotate, the worm gear can drive the screw to rotate, and drive the movable base to rise and fall through the nut.

[0016] Furthermore, the first lifting mechanism includes two opposing scissor-fork telescopic frames and a drive assembly; the top of the base and the bottom of the construction platform are each provided with two opposing fixed plates and two sliding grooves; one fork arm at any end of the scissor-fork telescopic frame is hinged to the corresponding fixed plate, and the other fork arm is slidably disposed in the corresponding sliding groove via a movable shaft; the movable shaft is connected between the two scissor-fork telescopic frames, and the drive assembly is disposed on the top of the base; the drive assembly can drive the movable shaft near the base to move, and when the movable shaft slides along the corresponding sliding groove, it can drive the two scissor-fork telescopic frames to extend and retract synchronously.

[0018] Furthermore, the top of the construction platform is equipped with a railing, and the railing has gaps on both sides facing and away from the suspended platform.
[0019] Compared with the prior art, this utility model has the following advantages:
[0020] The construction lifting platform described in this utility model, through the setting of a suspended basket and a gantry frame, allows the rotating shaft on the gantry frame, driven by a drive motor, to control the lifting and lowering of the suspended basket by winding and unwinding cables. This enables the suspended basket to be loaded with tools or light goods and then lifted to the required height, making it easier for workers to retrieve goods and tools, thus improving construction efficiency and safety.
[0021] In addition, a limiting frame is provided at the bottom of the gantry frame to restrain the suspended platform and limit its sway, thus ensuring its stability.

[0037] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0038] This embodiment relates to a construction lifting platform. In terms of overall structure, it includes a base 1, a first lifting mechanism 3 disposed on the base 1, a construction platform 2 driven by the first lifting mechanism 3 to move along the height direction, and a suspended basket 4 disposed on one side of the construction platform 2.
[0039] The construction platform 2 has a gantry frame 5 on one side, with a horizontally rotating shaft 501 and a drive motor 502 that drives the shaft 501 to rotate. The suspended platform 4 has two spaced-apart lifting beams 401, each topped with a lifting ring. The shaft 501 has two cables 503 wound around it, each cable 503 having a hook at its end for attaching to the lifting ring. When the shaft 501 is driven to rotate, the suspended platform 4 can be raised and lowered by winding and unwinding the cables 503.
[0040] As described above, through the setup of the suspended platform 4 and the gantry frame 5, the rotating shaft 501 driven by the drive motor 502 on the gantry frame 5 can control the lifting and lowering of the suspended platform 4 by winding and unwinding the cable 503, so that the suspended platform 4 can be loaded with tools or light goods and then lifted to the required height, so that the workers can easily retrieve the goods and tools, thereby improving construction efficiency and safety.
[0041] Based on the above overview, specifically, in this embodiment, the bottom end of the gantry 5 is provided with a limiting frame 504, which is connected to the construction platform 2. The suspended platform 4 can be fitted inside the limiting frame 504, and the limiting frame 504 can constrain the suspended platform 4 in the horizontal direction. By setting the limiting frame 504, the swaying of the suspended platform 4 can be limited when it is raised to the construction platform 2, thus ensuring the stability of the suspended platform 4, facilitating personnel to retrieve tools and goods, and improving safety.
[0042] In this embodiment, the base 1 includes a movable seat 101, and each of the four corners of the bottom of the movable seat 101 is provided with casters 1011. The casters 1011 enable the construction lifting platform of this embodiment to be pushed, improving its mobility. In specific implementations, to ensure the stability of the construction lifting platform, the casters 1011 can be casters with a locking function to ensure that the construction lifting platform will not move after reaching the designated position.
[0043] Since a hoisting basket 4 for lifting goods is provided on one side of the construction platform 2, in order to further improve the stability of the construction lifting platform, the base 1 of this embodiment also includes a support base 102 provided on the movable base 101, and a second lifting mechanism provided between the support base 102 and the movable base 101. The top of the support base 102 is provided with a first lifting mechanism 3, and the side of the support base 102 is provided with a plurality of L-shaped support plates 1021.
[0044] When the movable seat 101 is driven to descend by the second lifting mechanism, each caster wheel 1011 can touch the ground, and the support plate 1021 is separated from the ground. When the movable seat 101 is driven to rise by the second lifting mechanism, each caster wheel 1011 is separated from the ground, and each support plate 1021 touches the ground.
[0045] Thus, through the arrangement of the support base 102 and the second lifting mechanism, the second lifting mechanism can change the distance between the support base 102 and the ground, so that the support plate 1021 of the support base 102 can abut against the ground, separating the casters 1011 from the ground, thereby allowing the support plate 1021 to play a supporting role and further improving the stability of the construction lifting platform. In specific implementation, the support base 102 has a rectangular plate structure, and the support plate 1021 is arranged on the four sides of the support base 102.
[0046] To improve the supporting effect of the support plate 1021, this embodiment provides a pad 1022 for abutting against the ground on the side of the support plate 1021 facing the ground. In specific implementation, the pad 1022 can be made of an elastic material, such as rubber. By abutting against the ground with the pad 1022, the supporting plate 1021 can ensure its effective contact with the ground. The pad 1022 can undergo a certain degree of deformation to ensure that the support base 102 can be stably supported on a not completely level ground.
[0047] Specifically, the second lifting mechanism in this embodiment is a screw jack, including a housing, a screw rotatably disposed within the housing, a worm gear coaxially connected to the screw, a worm meshing with the worm gear, and a nut screwed onto the screw. The housing is located at the bottom of the support base 102, the nut is located on the movable base 101, and the screw can pass through the movable base 101. When the worm is driven to rotate, the worm gear can drive the screw to rotate, and through the nut, drive the movable base 101 to rise and fall. By setting up the screw jack, the support base 102 can be effectively driven to rise and fall, thereby changing the distance between the support base 102 and the ground. In specific implementations, this embodiment can also use other types of screw jacks with structures well known to those skilled in the art, as long as they can achieve the rising and falling of the support base 102.
[0048] To improve the stability of the lifting and lowering of the support base 102, four screw jacks are configured, located at the four corners near the bottom of the support base 102. The two worm gears of two screw jacks on the same side are coaxially connected via a first T-type commutator, and the two first T-type commutators are connected via a second T-type commutator. The input shaft of the second T-type commutator extends through a support plate 1021 to the outside of the base 1, and a handwheel 1023 is connected to the end of the input shaft. That is, the output shaft of a first T-type commutator is connected between the worm gears of two screw jacks on the same side, and the input shafts of the two first T-type commutators are connected to the output shaft of the second T-type commutator. Furthermore, the screw jacks, the first T-type commutators, and the second T-type commutators are arranged in an "I" shape at the bottom of the support base 102. When the handwheel 1023 is rotated, it drives the input shaft of the second T-type commutator, which in turn drives the screw lifting mechanisms to rise and fall synchronously through the two first T-type commutators. This improves the stability of the lifting of the support base 102 and facilitates operation by the operator. In specific implementation, both the first and second T-type commutators in this embodiment are conventional bevel gear commutators well known to those skilled in the art.
[0049] As a specific implementation, the first lifting mechanism 3 includes two opposing scissor-fork telescopic frames 301 and a drive assembly. The top of the base 1 and the bottom of the work platform 2 are each provided with two opposing fixed plates 302 and two sliding grooves 303. One fork arm at each end of the scissor-fork telescopic frame 301 is hinged to the corresponding fixed plate 302, and the other fork arm is slidably disposed in the corresponding sliding groove 303 via a movable shaft 3011. The movable shaft 3011 connects the two scissor-fork telescopic frames 301, and the drive assembly is located on the top of the base 1. The drive assembly can drive the movable shaft 3011 near the base 1 to move. When the movable shaft 3011 slides along the corresponding sliding groove 303, it can drive the two scissor-fork telescopic frames 301 to extend and retract synchronously. Using the scissor-fork telescopic frame 301 structure as the lifting mechanism has the advantages of simple and reliable structure and long lifting stroke. At the same time, by driving the movable shaft 3011 to slide along the corresponding slide groove 303 through the drive component, the two forks at the end of the scissor fork telescopic frame 301 can open or close, so as to effectively drive the scissor fork telescopic frame 301 to rise and fall.
[0050] Specifically, in this embodiment, the driving component is an electric push rod 304. The driving end of the electric push rod 304 can push against the movable shaft 3011, causing the movable shaft 3011 to move along the slide groove 303. Through the arrangement of the electric push rod 304, the driving end of the electric push rod 304 has a large driving force, which can effectively drive the scissor fork telescopic frame 301 to rise and fall. At the same time, the electric push rod 304 relies solely on electric power, without a hydraulic power source, for ease of use. In a specific implementation, the driving end of the electric push rod 304 is hinged to the movable shaft 3011.
[0051] Finally, the top of the construction platform 2 in this embodiment is equipped with a railing 201 to improve the safety of the construction platform 2 and prevent personnel from falling. In addition, the railing 201 has openings on both sides facing and away from the suspended basket 4. The opening facing the suspended basket 4 makes it easy for workers to access tools and materials, and the opening away from the suspended basket 4 allows workers to climb onto the construction platform 2.
[0052] In summary, the construction lifting platform of this embodiment, through the setup of the suspended basket 4 and the gantry frame 5, allows the rotating shaft 501 on the gantry frame 5, driven by the drive motor 502, to control the lifting and lowering of the suspended basket 4 by the winding and unwinding of the cable 503. This enables the suspended basket 4 to be loaded with tools or light goods and then lifted to the required height, making it easier for workers to retrieve goods and tools, thus improving construction efficiency and safety.
[0053] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
