Description

Technical Field

[0001] The utility model relates to the technical field of rotating structures, in particular to a rotating structure of an arm-type lifting work platform. Background Art

[0002] Aerial work platforms are products that serve various industries for high-altitude work, equipment installation, maintenance and other mobile high-altitude operations. In order to realize the rotation of the upper part, existing aerial work platforms will set a support between the turntable and the chassis to connect the two. At the same time, in order to smoothly deliver the pipeline from the turntable to the chassis without being affected by the rotation of the turntable, a rotating body with its own rotor and stator is set between them. The upper side of the rotating body is connected to the turntable through left and right connecting brackets, and the rotating body is connected to the above-mentioned connecting brackets through transition brackets, so that the rotor of the rotating body is completely fixed on the turntable. The lower side of the rotating body is connected to the stator through a limit bracket, and a mounting wire seat is provided on the chassis, and a limit plate is assembled. The above-mentioned limit bracket and the limit plate are connected by a slot to achieve complete limitation of the stator.

[0003] The rotating rotor and stator are fixed to the turntable and chassis respectively. As the turntable rotates freely, the pipelines passing through them will not be affected. However, in the actual assembly process, the turntable, support parts and chassis must be fully assembled before the above-mentioned rotating body assembly process can be carried out. The overall assembly is difficult and the reserved assembly space is very demanding. It is inevitable that there will be bumps and rust caused by the flow, which will affect the service life of the parts. Utility Model Content

[0004] Aiming at the problem that the existing aerial work platform is difficult to install as a whole, the utility model provides a rotating structure of an arm-type lifting work platform to solve the above problem.

[0005] The technical solution of the utility model is as follows:

[0006] A rotating structure of an arm-type lifting work platform includes a turntable, a chassis is provided below the turntable, and the two are connected by a support member; a limit plate is installed on the upper surface of the turntable, and the limit plate is Z-shaped; a limit slot is provided at the lower part of the limit plate; a limit bracket is clamped in the limit slot; the limit bracket is connected to the rotor of the rotating body; the chassis is provided with a connecting bracket; the connecting bracket is connected to the transition bracket; and the connecting bracket is connected to the stator of the rotating body.

[0007] Furthermore, the side wall of the rotor is provided with a threaded hole 1, and the side wall of the stator is provided with a threaded hole 2; threaded hole 1 and threaded hole 2 are provided with standard parts, and the limit bracket is connected to the rotor through the standard parts; the transition bracket is connected to the stator through the standard parts.

[0008] Furthermore, the limit plate is provided with two mounting holes on one side of the turntable, and standard fixings can be used to fix the limit plate on the turntable; a limit slot is provided on the side of the limit plate away from the turntable, which can be connected to the limit bracket assembled in advance through the slot to achieve the overall left and right rotation limit, that is, to completely limit the rotor of the rotating body on the turntable.

[0009] Furthermore, two circular holes are provided at one end of the limit bracket away from the slot, which are used to completely fix the limit bracket on the side of the rotor through fixing standard parts. A snap-in piece is provided on the upper side of the limit bracket, which can be connected to the limit plate on the turntable through the slot to achieve overall left and right rotation limit, and at the same time completely limit the rotor on the turntable.

[0010] Furthermore, the connecting bracket is provided with four circular holes on one side of the chassis, which are used to fix the connecting bracket to the chassis through fixing standard parts, and two long holes are provided on the side of the connecting bracket away from the chassis, which are used to connect the connecting bracket to one side of the transition bracket through fixing standard parts, and the other side of the transition bracket is connected to the side of the stator, so as to achieve complete fixing of the stator of the rotating body on the chassis.

[0011] Furthermore, the connecting bracket is provided with a reinforcing rib 1. Since the connecting bracket is a cantilever structure, it will bump up and down during the movement of the whole machine. Therefore, the connecting bracket is further provided with a reinforcing rib 1 for overall reinforcement, making the connecting bracket more reliable.

[0012] Furthermore, four circular holes three are provided at one end of the transition bracket close to the stator, which are used to completely fix the transition bracket on the stator through fixing standard parts, and two circular holes four are provided at the other end of the transition bracket, which are used to fixedly connect the transition bracket with the connecting bracket through fixing standard parts, so as to completely fix the stator on the chassis.

[0013] Furthermore, a second reinforcing rib is provided on the transition bracket to increase the overall strength of the transition bracket and make the transition bracket more reliable.

[0014] The working principle of the present invention is as follows: during actual assembly, the lower side of the rotating body can be first connected to the stator through a transition bracket, and at the same time, a mounting wire seat is provided on the chassis, and a connecting bracket is assembled, and the above-mentioned transition bracket and the connecting bracket are connected through standard parts, and the stator of the rotating body is completely fixed on the chassis, and the limit bracket on the upper side of the rotating body is fixed and assembled through standard parts, and then the support parts and the turntable are assembled normally on the chassis, and finally the slot provided on the above-mentioned limit plate is connected with the limit bracket assembled in advance by the slot and finally fixed on the turntable, thereby realizing the overall assembly of the entire rotating body fixing device.

[0015] The beneficial effects of the present invention are:

[0016] The rotation structure of the arm support type lifting work platform improves the arrangement of the rotary body, promotes the optimization mode of monomer assembly by integrated assembly, improves the time efficiency of overall assembly, makes the assembly mode more humanized, and conforms to ergonomics. This process can also transport the rotary body and associated assembly components to the overall assembly station after assembly to the chassis, greatly reduce the assembly space, realize the assembly line operation of different stations, and improve the assembly efficiency.

This improves the layout of the rotating body, achieving an optimized model of single-unit assembly from integrated assembly, increasing the time efficiency of the overall assembly and making the assembly mode more user-friendly and ergonomic. This process also allows the rotating body and associated assembly components to be assembled to the chassis before being transferred to the entire assembly station, greatly reducing the assembly space, enabling assembly line operations at different stations, and improving assembly efficiency.

[0033] like Figure 1 、 Figure 2 and Figure 6 As shown, a rotating structure of an arm-type lifting work platform includes a turntable 1, a chassis 3 is provided below the turntable 1, and the two are connected by a support member 2; a limit plate 4 is installed on the upper surface of the turntable 1, and the limit plate 4 is Z-shaped; a limit slot 4.2 is provided at the bottom of the limit plate 4; a limit bracket 5 is clamped in the limit slot 4.2; the limit bracket 5 is connected to the rotor 8.3 of the rotating body 8; the chassis 3 is provided with a connecting bracket 6; the connecting bracket 6 is connected to the transition bracket 7; the connecting bracket 6 is connected to the stator 8.4 of the rotating body 8.
