Description

A working platform for construction Technical Field

[0001] The invention belongs to the technical field of building construction equipment, in particular to a working platform for building construction. Background Art

[0002] In the field of construction, construction work platforms are usually used to facilitate workers in transporting construction materials to higher floors. Most of these construction work platforms are liftable, making them convenient for workers to use.

[0003] At present, the construction process of a liftable work platform usually involves first building exterior wall scaffolding columns, and then installing a movable work platform on the columns. The work platform is driven by a motor to move up and down on the scaffolding columns to achieve lifting. However, the installation process of the scaffolding columns is cumbersome, and the scaffolding columns need to be erected section by section, and each section of the scaffolding columns needs to be drilled in the exterior wall and wall connecting parts installed, which makes the installation and disassembly processes very cumbersome. At the same time, the lifting of the work platform is achieved by means of a motor-driven gear, which cooperates with a toothed plate for lifting. After the work platform reaches a certain floor, there is no stable positioning device, and the work platform is fixed only by a stuck gear. When the loaded material is heavy or it is used for a long time, it will cause the work platform to sink, and there is even a risk of overturning.

Obviously, the described embodiments 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.

[0028] As shown in Figures 1 to 7, an embodiment of the present invention provides a work platform for construction, including a work platform body 1, a rotatable protective door 11 is installed on the surface of the work platform body 1, and a support plate 2 is installed on the rear surface of the work platform body 1.

A lifting structure 3 is provided between the support plate 2 and the work platform body 1, and a positioning structure 4 for pressing against the upper and lower end surfaces of the building floor and a stabilizing structure 5 for clamping the outer end surface of the floor to ensure the stable rise of the work platform body 1 and the support plate 2 are respectively provided on the side of the support plate 2 away from the work platform body 1.

[0029] The effects achieved by the above technical solution are as follows: through the arrangement of the positioning structure 4, the lifting structure 3 and the stabilizing structure 5, the positioning structure 4 is used to unfold after reaching the predetermined floor, and to press and position the upper and lower floor slabs of the floor to ensure the stability of loading and unloading; the lifting structure 3 is used to move up and down to adjust the height of the working platform body 1 after positioning, so as to make it reach the best loading and unloading position of the floor, making it convenient for workers to enter the floor; the stabilizing structure 5 is used to output through the electric push rod 54 when the entire device needs to be raised, so that the U-shaped part 55 is clamped on the floor slab, and relatively descends when the entire device rises, to ensure the rising stability.

[0030] As shown in Figures 3, 4 and 6, in this embodiment, the positioning structure 4 includes two stabilizing seats 41, one side of the stabilizing seat 41 is fixedly connected to the support plate 2, and an inner groove is provided on the surface of the stabilizing seat 41. Positioning plates 42 are installed on the inner wall of the inner groove near the upper and lower ends of the stabilizing seat 41. The two positioning plates 42 can rotate relative to each other inside the inner groove. Two hydraulic cylinders 43 are rotatably connected to the inner wall of the inner groove near the center of the stabilizing seat 41, and the output ends of the two hydraulic cylinders 43 are rotatably connected to the upper and lower positioning plates 42 respectively.

[0031] The effect achieved by the above technical solution is: through the setting of two rotatable positioning plates 42, the hydraulic cylinder 43 can output and drive the positioning plates 42 to rotate outward until they abut the relative end faces of the upper and lower floor slabs of any floor, thereby ensuring the stability of the working platform body 1 without the need to open holes in the floors.

[0032] Among them, several positioning holes 45 are opened on both sides of the stabilizing seat 41 near the upper and lower ends, and a positioning rod 451 is passed through the inner wall of the positioning hole 45, and the positioning rod 451 passes through the interior of the positioning plate 42.

[0034] In addition, one end of the positioning plate 42 is fixedly connected to a stabilizing square plate 44 , and a plurality of anti-slip grooves are provided on opposite sides of the two stabilizing square plates 44 .

[0035] The effect achieved by the above technical solution is: the anti-slip grooves provided on the surface of the stabilizing square plate 44 are used to increase the friction force when contacting with the rough surface of the floor slab, thereby ensuring the stability of the contact.

[0036] As shown in Figure 1 and Figure 2, in this embodiment, the lifting structure 3 includes several positioning blocks 31, one side of the positioning block 31 is fixedly connected to the support plate 2, and the internal rotation of the positioning block 31 is connected to a screw 32.

The driving disk 342 and the inner wall of the driving disk 343 are connected by a belt 344.

[0037] The effect achieved by the above technical solution is: through the drive of the drive motor 341, the two transmission plates 343 on both sides can be driven to rotate, and then the screw 32 can be rotated, driving the movable block 33 on the arc surface of the screw 32 to move up and down, so that the working platform body 1 can be adjusted up and down, and then adjusted to the optimal loading and unloading position, making it convenient for workers to carry materials into the floor.

[0038] The two driving disks 342 are connected to the transmission disks 343 on the two screw rods 32 through belts 344 respectively.

[0039] The effect achieved by the above technical solution is: by independently setting the two drive disks 342, and the two belts 344 are respectively connected to the transmission disks 343 on the two screw rods 32, while driving the two screw rods 32 to rotate synchronously, the problem of large wear of a single belt 344 is avoided.

[0040] As shown in Figures 3, 5 and 7, in this embodiment, the stabilizing structure 5 includes two movable rails 51, one side of the movable rail 51 is fixedly connected to the support plate 2, the two movable rails 51 are located between the two stabilizing seats 41, the inner wall of the movable rail 51 is slidably connected with a slider 53, the interior of the movable rail 51 is fixedly connected with a fixed rod 52, the fixed rod 52 is passed through the interior of the slider 53, one side of the slider 53 is fixedly connected with an electric push rod 54, the output end of the electric push rod 54 is fixedly connected with a U-shaped part 55, and the inner surface of the U-shaped part 55 is treated as a circular arc surface.

[0041] The effect achieved by the above technical solution is: through the setting of the stabilizing structure 5, when the entire device needs to be lifted, the U-shaped part 55 is slid to the position facing the floor by sliding the slider 53, and then the electric push rod 54 is output to drive the U-shaped part 55 to be pushed out, so that the outer end surface of the floor is stuck in the U-shaped part 55, so as to position the entire device when it rises, and keep the slider 53 sliding downward relative to the entire device in the movable rail 51, thereby ensuring the stability of the ascent.

[0042] As shown in FIG. 1 , two rear hoisting blocks 21 are fixedly connected to the upper surface of the support plate 2 , and two front hoisting blocks 22 are fixedly connected to the upper surface of the work platform body 1 .

[0043] The effect achieved by the above technical solution is: through the setting of the lifting block, a rope pulling mechanism can be set on the top floor to connect the traction wire rope with the front lifting block 22 and the rear lifting block 21, thereby facilitating the lifting of the entire device.

[0044] Working principle and usage process:

[0045] During use, the front lifting block 22 and the rear lifting block 21 are connected by a traction wire rope, and the upper end of the traction wire rope is connected to the traction equipment at a high place. Workers can open the protective door 11 to carry building materials into the working platform body 1, and then close the protective door 11. Then, the entire device can be pulled up by the traction rope. When it is necessary to stop at a predetermined floor, the two hydraulic cylinders 43 output power to drive the positioning plate 42 to extend outward until the two stable square plates 44 abut against the relative end surfaces of the upper and lower floor slabs to complete the positioning. Then, the drive motor 341 rotates to fine-tune the up and down positions of the working platform body 1. Workers can enter the floor through the opening in the middle of the support plate 2, which also facilitates the handling of materials. When it is necessary to ascend floor by floor, first slide the U-shaped piece 55 to the uppermost end, and the electric push rod 54 outputs power to make the U-shaped piece 55 engage the outer end surface of the floor slab. Then the hydraulic cylinder 43 contracts to retract the positioning plate 42, and then the traction rope pulls the entire device up. At this time, the slider 53 moves downward relative to the entire device in the movable rail 51 to ensure the stability of the upward movement.
