Description
Technical Field
The invention relates to an array bolt hoisting underframe used in the field of motor engineering.
Background
The conventional large-scale sitting bearing motor cannot be directly hoisted due to large integral weight. The chassis is easy to generate plastic deformation, so that the gap deviation of the stator and the rotor is caused, and the performance of the motor is influenced. Therefore, after the motor is debugged, the motor needs to be disassembled and separately boxed. And the assembly is carried out after the transportation to the site, so that a large amount of labor and material cost is consumed. In addition, in some application scenarios, for example, in a marine motor application scenario, due to limited installation and construction conditions, split disassembly and assembly operations cannot be performed generally, and the motor including the underframe needs to be hung and installed integrally. If the motor has special working conditions such as inclination and swing, the chassis design needs to be carried out by considering the strength of the chassis and the hoisting performance of the whole machine in order to meet the requirements of the working conditions.
Disclosure of Invention
The invention aims to overcome the defects of the prior art and provides an array bolt hoisting underframe, which can effectively reduce the disassembly and assembly cost of a motor and realize the integral hoisting of the motor.
One technical scheme for achieving the above purpose is as follows: an array bolt hoisting underframe comprises an underframe base;
the chassis base is of a rectangular frame structure and is divided into a front bearing side, a rear bearing side and two sides, bearing top plates are arranged on the chassis base on the front bearing side and the rear bearing side, side top plates are arranged on the chassis base on the two sides, the bearing top plates and the side top plates are supported on a bottom plate through supporting plates, and the height of the bearing top plates is higher than that of the side top plates;
hook-shaped connecting plates are respectively arranged at two ends of the bearing top plate and are fixedly connected with the bearing top plate through arrayed bolts, and a lifting tool is welded on each hook-shaped connecting plate;
and two ends of the side top plate are respectively provided with a bearing support platform, and the height of the bearing support platform is higher than that of the bearing top plate.
Furthermore, the bearing top plate is provided with a supporting platform knot bent towards the side top plate, and the supporting platform is supported on the side top plate through a supporting plate.
Still further, the supporting platform is provided with a triangular supporting reinforcing rib for supporting the bearing supporting platform.
Furthermore, a triangular support reinforcing rib used for supporting the bearing top plate on the bottom plate is arranged on the inner side of the bearing top plate.
Furthermore, the middle part of the triangular support reinforcing rib is provided with a lightening hole.
According to the array bolt hoisting underframe, the underframe base is of a rectangular frame structure, the bearing top plate and the side top plate are respectively supported on the underframe through the supporting plate, and the height of the bearing top plate is higher than that of the side top plate; hook-shaped connecting plates are respectively arranged at two ends of the bearing top plate and are fixedly connected with the bearing top plate through arrayed bolts, and a hoisting tool is welded on each hook-shaped connecting plate; and two ends of the side top plate are respectively provided with a bearing support platform, and the height of the bearing support platform is higher than that of the bearing top plate. The array bolt hoisting underframe has high mechanical structure strength, stably supports the motor, can realize the integral hoisting operation of the motor, and is suitable for narrow operation space in which the motor is difficult to disassemble and assemble.
Drawings
Fig. 1 is a schematic structural diagram of an array bolt hoisting underframe according to the invention.
Detailed Description
In order to better understand the technical solution of the present invention, the following detailed description is made by specific examples:
referring to fig. 1, an array bolt hoisting underframe according to the present invention includes an underframe base.
The chassis base is rectangular frame structure, divide into front bearing side, rear bearing side and both sides, and the chassis base of front bearing side and rear bearing side is equipped with bearing roof 1, and the chassis base of both sides is equipped with side roof 2, and bearing roof 1 and side roof 2 support on the bottom plate through backup pad 3, and bearing roof 1 highly is higher than side roof 2, and the two contact site welds. The inside of the bearing top plate 1 is provided with a triangular support reinforcing rib 4 for supporting the bearing top plate 1 on the bottom plate. The bearing top plate 1 is provided with a supporting platform knot 11 bent towards the side top plate, and the supporting platform 11 is supported on the side top plate 2 through a supporting plate 3. Two ends of the side top plate 2 are respectively provided with a bearing support platform 21, and the height of the bearing support platform 21 is higher than that of the bearing top plate 1. The support platform 11 is provided with a triangular support reinforcing rib 4 for supporting the bearing support platform 21. The bearing support table 21 is used for supporting and fixing the bearing end of the motor, and the lifting design is adopted, so that the center height of the motor rotor is reduced, and the operation stability of the motor can be improved. The middle parts of all the triangular support reinforcing ribs 4 are provided with lightening holes.
The tailor-welded position of the bottom plate of the chassis base is the lower part of the bearing top plate 1, and the tailor-welded position of the bottom plate is staggered with the tailor-welded position of the bearing top plate 1 and the side top plate 2, so that the stress of a welding seam is dispersed, and the deflection of the whole chassis is improved.
The two ends of the bearing top plate 1 are respectively provided with a hook-shaped connecting plate 5, the hook-shaped connecting plates are fixedly connected with the bearing top plate 1 through the arrayed bolts, each hook-shaped connecting plate 5 is welded with a hoisting tool 51 which can bear the weight of the motor and meet the design requirement, the arrayed bolts and the hoisting tool can be detached, the weight of the whole machine can be reduced, and the occupation ratio of the space of the motor is reduced.
It should be understood by those skilled in the art that the above embodiments are only for illustrating the present invention and are not to be used as a limitation of the present invention, and that changes and modifications to the above described embodiments are within the scope of the claims of the present invention as long as they are within the spirit and scope of the present invention.
