Description

Technical Field

[0001] The utility model relates to the technical field of aerial work platforms, in particular to a multifunctional aerial work platform. Background Art

[0002] Aerial work platforms are products that serve various industries' aerial work platforms, equipment installation, maintenance and other movable aerial work platforms. Aerial work platform related products mainly include seven categories: scissor-type aerial work platforms, vehicle-mounted aerial work platforms, articulated arm aerial work platforms, straight arm aerial work platforms, aluminum alloy aerial work platforms, cylinder-type aerial work platforms, and trailer-type aerial work platforms.

[0003] For example, an aerial work platform with publication number CN208814610U includes a platform body, a cavity for facilitating the installation of an L-shaped reinforcement plate, and the cooperation of a slide groove and a slide rod makes it easy to fix and adjust the L-shaped reinforcement plate, which is convenient for use and increases the operating area of ​​the platform body. The telescopic fixing rod not only enhances the stability of the L-shaped reinforcement plate, but also plays a protective role;

[0004] The aerial work platform is provided with an electric telescopic rod on the platform body and the supporting base, and a mounting plate and a guardrail are provided on the electric telescopic rod to realize aerial work. However, since there is no structure for transporting tools and materials on the mounting plate, when the mounting plate is raised and lowered to a specified height for aerial work, if some tools or materials are needed, the mounting plate needs to be lowered again and the operator needs to go down to get them, which not only wastes time, but also poses certain safety hazards when carrying tools or materials to climb. At the same time, there is no fixed structure provided under the platform body and the supporting base. When aerial work is performed at some inclined angles, the device is easily moved due to the influence of the wheels under the platform body and the supporting base, so the actual use effect is not good. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides a multifunctional aerial work platform, which solves the problem that the existing aerial work platforms do not have a structure for transporting tools and materials on the mounting plate. Therefore, when the mounting plate is raised and lowered to a specified height for aerial work, if some tools or materials are needed, the mounting plate needs to be lowered again and the operator needs to go down to get them. This not only wastes time, but also poses certain safety hazards when carrying tools or materials to climb. At the same time, when aerial work is performed at some inclined angles, the device is prone to movement due to the influence of the platform body and the wheels under the support base.

[0006] To achieve the above objectives, the utility model is implemented through the following technical solutions: a multifunctional aerial work platform, including a base plate and a power box, the upper ends of the base plate are fixedly connected to the power box, a pair of multi-stage screw rods are connected to the upper interior of the power box, a platform is fixedly connected to the upper rotating head of the multi-stage screw rods, a pair of first vertical plates are fixedly connected to the middle of the upper surface of the platform, rollers are rotatably connected to the upper inner sides of the left and right first vertical plates, a lifting mechanism is installed on the outer wall of the rollers, a connecting mechanism is installed below the base plate, and wheels are fixedly connected to the lower ends of the base plate.

[0007] Preferably, the lifting mechanism includes a first rope wound and fixedly connected to the roller, and a connecting block is fixedly connected below the first rope, a plurality of second ropes are fixedly connected below the connecting block, and a hanging box that fits the gap with the inner wall of the platform opening is fixedly connected below the second ropes, and a handle is fixedly connected to the outer wall of the roller shaft at the left end of the roller.

[0008] Preferably, a fence is fixedly connected to the upper surface of the platform.

[0009] Preferably, a ladder is fixedly connected to the right side of the upper surface of the base plate, and a pair of connecting frames fixedly connected to the outer walls of adjacent multi-stage screw rods are fixedly arranged above the left side of the ladder.

[0010] Preferably, the connecting mechanism includes a pair of first rectangular blocks fixed to the lower surface of the bottom plate, and the front and rear ends of the first rectangular blocks are rotatably connected to connecting rods via a rotating shaft, and a second rectangular block is rotatably connected to the bottom of the connecting rod via a rotating shaft, and a cross bar is matched with the inner wall gap at the through holes of the left and right second rectangular blocks, and second vertical plates are fixed to the left and right sides of the cross bar, and a toothed vertebral plate is fixed to the lower surface of the second vertical plate.

[0011] Preferably, a pair of cylinders are fixedly connected in the middle of the lower surface of the bottom plate, and a top plate in contact with the outer wall of the connecting rod is fixedly connected to the outer side of the cylinder.

[0012] Beneficial Effects

[0013] The utility model provides a multifunctional aerial work platform, which has the following beneficial effects:

[0014] The user can climb to the platform through the ladder, and then use the power structure such as the driving motor in the power box to drive the multi-stage screw to move, so that the multi-stage screw can drive the platform to rise, so as to realize high-altitude work. When some tools or materials are needed, some tools or materials can be placed in the hanging box with the help of another staff member, and then the handle is turned to drive the roller to rotate, and the first wire rope is wound up by the roller, so that the first wire rope drives the hanging box to move through the connecting block and the second wire rope, and the hanging box is pulled up to take the tools or materials in the hanging box. This not only saves time, but also does not require users to carry tools or materials for climbing, so the safety is relatively high;

[0015] The cylinder can be started to drive the top plate to extend, so that the top plate can squeeze the connecting rod, so that the connecting rod cooperates with the first rectangular block to drive the second rectangular block to move at the cross bar. At the same time, the second rectangular block will drive the tooth vertebral plate to move through the cross bar and the second vertical plate, so that the bottom of the tooth support plate is closely fitted with the ground. In this way, the friction between the device and the ground can be increased, thereby improving the overall stability and preventing the device from moving easily, so the actual use effect is better.
