Description

Technical Field

[0001] This utility model relates to the field of mechanical equipment technology, and in particular to a lifting device for motor alignment. Background Technology

[0002] When replacing the motor of a sulfur dioxide blower, because the equipment is installed outdoors, a crane is needed to lift the motor to a height of 800mm for alignment each time. Since the equipment's coupling is a rigid connection, the coaxiality requirement for the blower is also quite high, and the motor is very heavy. Previously, alignment required the crane to be present throughout the entire process. Adjusting shims only required lifting the motor slightly by 3-5mm, but this was insufficient with the crane. Each time shims were added or removed, the motor needed to be re-aligned horizontally, which was time-consuming, labor-intensive, and inaccurate, failing to guarantee the equipment's operational lifespan.

[0003] The insufficient coaxiality precision of the sulfur dioxide blower makes it impossible to guarantee the equipment's operating cycle, resulting in an increase in the number of maintenance operations, which increases the labor intensity of employees. Moreover, once an accident occurs and the machine stops, it will directly affect the normal production of the recycling operation area.

[0004] According to research, the current domestic practice mainly involves using cranes or hydraulic jacks for lifting operations. However, there is no dedicated lifting device available for narrow spaces like this one where hydraulic jacks cannot fit. Utility Model Content

[0005] In view of the shortcomings of the existing technology, this utility model provides a jacking device for motor alignment, which overcomes the shortcomings of the existing technology and effectively solves the problems of time-consuming and labor-intensive crane operation and high daily operating costs.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A motor alignment lifting device includes a spiral lifting assembly and a height monitoring assembly. The spiral lifting assembly includes a base, a nut welded to the outer wall of the top of the base, a threaded rod screwed to the inner wall of the nut, and a top block welded to the outer wall of the top of the threaded rod.

[0008] The height adjustment monitoring component consists of a bottom ring, a scale plate, a top ring, a connecting rod, and a pointer. The bottom ring is rotatably connected to the inner wall of the base, the scale plate is welded to one side of the outer wall of the bottom ring, the top ring is rotatably connected to the outer wall of the threaded rod, the connecting rod is welded to one side of the outer wall of the top ring, and the pointer is located at one end of the connecting rod.

[0009] Preferably, the top outer wall of the nut has a threaded hole, and the threaded rod is screwed onto the inner wall of the threaded hole.

[0010] Preferably, the outer wall of the base is provided with an annular groove, and the bottom ring is rotatably connected to the inner wall of the annular groove.

[0011] Preferably, a fixing ring is welded to the top of the outer wall of the threaded rod, and the top ring is disposed between the fixing ring and the top block.

[0012] Preferably, a groove is formed on one side of the outer wall of the scale plate, and the connecting rod is slidably connected to the inner wall of the groove.

[0013] Preferably, the outer wall of one side of the scale plate is provided with scale lines, and the pointer points to one end of the scale lines.

[0014] Preferably, the top of the top block has a conical structure, and the bottom of the top block has a hexagonal structure.

[0015] The beneficial effects of this utility model are as follows:

[0016] 1. The motor alignment lifting device designed in this paper can be used by tightening the nut with a wrench and then turning the top block in the opposite direction with another wrench to lift and lower the motor. It is easy to use and occupies little space. It can be used for alignment and lifting operations in narrow spaces without the need for a crane, thus reducing the daily operating cost of the crane.

[0017] 2. The motor alignment lifting device in this design achieves the lifting and lowering of the top ring through the rotation between the nut and the threaded rod. This allows the pointer at one end of the connecting rod to mark the position of the scale line on the scale plate in real time, thereby enabling precise monitoring of the height of the motor being lifted and lowered in narrow spaces. This improves labor efficiency and facilitates its widespread use. Attached Figure Description
