Description

Technical Field

[0001] This utility model relates to the field of lifting platform technology, and in particular to a simple lifting platform for building construction with adjustable height. Background Technology

[0002] In the construction industry, lifting platforms are widely used. Simple lifting platforms, as a type of lifting platform, are widely used due to their convenient construction and simple operation. Simple lifting platforms are set up on construction sites and are mainly used to transport building materials and workers, sending them to designated heights.

[0003] In construction, simple lifting platforms are used to raise workers and building materials to a suitable height. Because the lifting platform is designed with guardrails around it, the height of the guardrails is generally constant. However, the height of the workers and the content of their work are different, so the required height of the guardrails is different. For example, the height required for bricklayers is about 1.2 meters, while the height required for equipment installers is only about 0.8 meters. If the guardrails are too low, the safety of construction will be reduced. If the guardrails are too high, it will affect the workers' work. Too high or too low will not only affect the progress of the work, but also reduce safety.

[0004] Therefore, how to provide a simple lifting platform for construction with adjustable height is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] One objective of this invention is to provide a simple, height-adjustable construction lifting platform. This invention solves the problem that the constant height of the guardrails on existing lifting platforms makes it difficult to adjust to the different heights and work content of different workers, thus affecting the normal operation of the work and reducing safety.

[0006] A height-adjustable simple construction lifting platform according to an embodiment of the present utility model includes a lifting frame, a platform plate provided on the side of the lifting frame, a fixed railing provided on the top of the platform plate near the outermost position, a lifting channel provided on the top of the fixed railing near the lifting frame, a lifting main frame provided inside the lifting channel, and a movable guardrail provided on the top of the lifting main frame; a drive component for adjusting the height of the lifting main frame is provided on the side of the fixed railing corresponding to the position of the lifting channel.

[0007] The surface of the platform plate is provided with a through groove corresponding to the position of the lifting main frame and the movable guardrail, and the through groove connects the upper surface and the lower surface of the platform plate.

[0008] The drive assembly includes a drive motor, a mounting base, a worm gear, a worm wheel, a connecting groove, and a toothed groove. The drive motor is fixedly connected to the side of the fixed fence, the mounting base is fixedly connected to the side of the fixed fence and is located directly above the fixed fence, the worm gear is rotatably connected to the mounting base, the connecting groove is opened on the side of the fixed fence and corresponds to the position of the worm gear, the worm wheel is rotatably connected to the side of the fixed fence, and the worm gear meshes with each other. The output shaft of the drive motor is fixedly connected to the end face of the worm gear, the toothed groove is opened on the side of the lifting main frame and corresponds to the position of the connecting groove, and one end of the worm wheel passes through the connecting groove and meshes with the toothed groove.

[0009] The side of the fixed fence is provided with a protective cover that covers the drive component.

[0010] The movable guardrail is provided with an opening and closing door assembly on the side away from the lifting frame. The opening and closing door assembly includes a mounting frame, a door body, and a locking assembly. The mounting frame is fixedly connected to the side of the movable guardrail away from the lifting frame. The opening and closing door body is rotatably connected to the surface of the mounting frame via a hinge. The door body is locked onto the surface of the mounting frame away from the hinge via the locking assembly.

[0011] The latch assembly includes a lock groove, a limiting groove, sliding levers, a lever, and a spring. The lock groove is located on one side of the door body near the mounting bracket. The limiting groove is located on the surface of the mounting bracket at the position corresponding to the lock groove. There are two sets of sliding levers, which are symmetrically slidably connected inside the limiting groove and engaged inside the lock groove. Both ends of the spring are fixedly connected to the opposite surfaces of the two sets of sliding levers and are movably connected inside the limiting groove. The lever is fixedly connected to the end of the two sets of sliding levers away from the lock groove, and the other end of the lever extends to the outside of the limiting groove and the mounting bracket.

[0013] The top of the fixed fence is equipped with an "n"-shaped clip, and a placement box is fixedly connected to the inside of the "n"-shaped clip.

[0014] The beneficial effects of this utility model are:

[0015] By setting up a drive component, a lifting main frame, and movable guardrails, the drive component moves the lifting main frame and movable guardrails on the fixed fence to achieve height control of the lifting main frame and movable guardrails. This allows the height of the movable guardrails and lifting main frame to be changed, thus matching the height of workers of different heights and doing different jobs. This solves the problem that the height of the guardrails on existing lifting platforms is constant, making it difficult to adjust to the height and job content of different workers, which affects the normal operation of work and reduces safety.

[0016] By installing an opening and closing door assembly, one side of the movable guardrail can be opened, making it convenient for staff to enter the platform to work.

[0017] By setting up placement boxes that are secured to a fixed fence with "n"-shaped clips, it is convenient to place workers' tools. Placing them on a platform board could cause them to slip. Furthermore, the "n"-shaped clips allow the placement boxes to be repositioned according to the actual situation. Attached Figure Description

Detailed Implementation

[0027] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0028] refer to Figure 1-7 In this embodiment, a lifting frame 1 is included. A platform plate 2 is provided on the side of the lifting frame 1. The platform plate 2 realizes the lifting function on the lifting frame 1. A fixed fence 3 is provided on the top of the platform plate 2 near the outermost position. A lifting through groove 4 is opened on the top of the fixed fence 3 near the lifting frame 1. A lifting main frame 5 is provided inside the lifting through groove 4. A movable guardrail 6 is provided at the top of the lifting main frame 5. A through groove 8 is opened on the surface of the platform plate 2 corresponding to the position of the lifting main frame 5 and the movable guardrail 6. The through groove 8 connects the upper surface and the lower surface of the platform plate 2. In this way, when the platform plate 2 rises, the lifting main frame 5 and the movable guardrail 6 will pass through the through groove 8 when they descend. This can increase the length of the lifting main frame 5 and the movable guardrail 6, and increase the range of motion of the lifting main frame 5 and the movable guardrail 6. Here, the movable guardrail 6 surrounds the outside of the fixed fence 3.

[0029] The side of the fixed fence 3, corresponding to the position of the lifting slot 4, is provided with a drive assembly 7 for adjusting the height of the lifting main frame 5. The drive assembly 7 includes a drive motor 9, a mounting base 10, a worm gear 11, a worm wheel 12, a connecting slot 13, and a toothed groove 14. The drive motor 9 is fixedly connected to the side of the fixed fence 3, the mounting base 10 is fixedly connected to the side of the fixed fence 3 and is located directly above the fixed fence 3, the worm gear 11 is rotatably connected to the mounting base 10, the connecting slot 13 is opened on the side of the fixed fence 3 and corresponds to the position of the worm gear 11, and the worm wheel 12 is rotatably connected to the side of the fixed fence 3. The worm gear 11 and the worm wheel 12 mesh with each other. The output of the drive motor 9... The shaft is fixedly connected to the end face of the worm gear 11. The tooth groove 14 is opened on the side of the lifting main frame 5 at the position corresponding to the connecting groove 13. One end of the worm wheel 12 passes through the connecting groove 13 and meshes with the tooth groove 14. When the height of the movable guardrail 6 and the lifting main frame 5 needs to be adjusted, the drive motor 9 needs to be started first. The start of the drive motor 9 will drive the worm gear 11 to rotate. The rotation of the worm gear 11 will drive the worm wheel 12 to rotate. The rotation of the worm wheel 12 will drive the tooth groove 14 to move up or down. The upward or downward movement of the tooth groove 14 will drive the lifting main frame 5 to move up or down. Thus, the lifting main frame 5 will drive the movable guardrail 6 to move up or down, thereby realizing the height adjustment of the movable guardrail 6.

[0030] refer to Figure 1-7 In this embodiment, a protective cover 15 is provided on the side of the fixed fence 3 corresponding to the position of the drive component 7 to cover the drive component 7. The protective cover 15 covers the outside of the drive component 7, and its purpose is to protect the entire position of the drive component 7.

[0031] refer to Figure 1-7In this embodiment, an opening and closing door assembly 16 is provided on the side of the movable guardrail 6 away from the lifting frame 1. The opening and closing door assembly 16 includes a mounting frame 17, a door body 18, and a locking assembly 19. The mounting frame 17 is fixedly connected to the side of the movable guardrail 6 away from the lifting frame 1. The opening and closing door body 18 is rotatably connected to the surface of the mounting frame 17 via a hinge. The door body 18 is latched onto the surface of the mounting frame 17 at a position away from the hinge via the locking assembly 19. The locking assembly 19 includes a lock groove 20, a limiting groove 21, a sliding latch 22, a lever 23, and a spring 24. The lock groove 20 is formed on the side of the door body 18 near the mounting frame 17, limiting... The positioning groove 21 is formed on the surface of the mounting bracket 17 corresponding to the locking groove 20. There are two sets of sliding latches 22, which are symmetrically slidably connected inside the limiting groove 21 and engaged inside the locking groove 20. The two ends of the spring member 24 are fixedly connected to the opposite surfaces of the two sets of sliding latches 22, and the spring member 24 is movably connected inside the limiting groove 21. The lever 23 is fixedly connected to the end of the two sets of sliding latches 22 away from the locking groove 20, and the other end of the lever 23 extends to the outside of the limiting groove 21 and the mounting bracket 17. The lever 23 is located on the side outside the mounting bracket 17 and the limiting groove 21. The door has anti-slip texture, and a guide rod 25 is vertically fixed inside the limiting groove 21. Two sets of sliding latches 22 and springs 24 are movably sleeved on the surface of the guide rod 25. The opening and closing door assembly 16 is designed here to open one side of the movable guardrail 6 into an opening shape, making it convenient for workers to enter the platform 2 to work. During operation, the two sets of levers 23 on the locking assembly 19 are moved closer together. The two sets of levers 23 moving closer together will cause the two sets of sliding latches 22 to move closer together. The two sets of sliding latches 22 moving closer together will separate from the lock groove 20. Then, the door 18 is rotated to allow the door to pass through. The hinge rotates to open one side of the movable guardrail 6, allowing the staff to enter the platform 2. Then, the door 18 is flipped by the hinge and brought closer to the sliding lever 22. Since the sliding lever 22 has a chamfered face near the lock groove 20, the door 18 rotates and presses the two sets of sliding levers 22, causing them to move closer together. As the two sets of sliding levers 22 move closer together, they slowly insert into the lock groove 20. Once fully inserted into the lock groove 20, the spring force of the spring 24 pushes the two sets of sliding levers 22 away from each other, causing them to lock into the lock groove 20. At this point, the door 18 is fixed.

[0032] refer to Figure 1-7 In this embodiment, the top of the fixed fence 3 is provided with an "n"-shaped card 26. The "n"-shaped card 26 is attached to the top of the fixed fence 3 and can be moved to a suitable position. The inner side of the "n"-shaped card 26 is fixedly connected to a placement box 27, which is used to place the tools of the staff, so that they do not need to be placed on the platform board 2.
