Problems solved by technology

[0002] The base frame and the motor body of the extra-large horizontal motor are transported separately, and the axis needs to be adjusted during on-site installation. The stator of this type of motor usually weighs 40 to 50 tons, and some are even larger than 70 to 80 tons. The friction between the chassis and the chassis is usually greater than 60kN. To overcome such a large friction and control the adjustment accuracy, it is usually necessary to set up an embedded horizontal support seat on the basis of the site, and then act on our motor through a hydraulic jack. The base plate of the base can be adjusted. Once the support base is buried in the foundation, it cannot be disassembled at any time, which affects the layout of on-site equipment and also creates a certain safety hazard for the daily operations of the on-site staff.
Moreover, hydraulic jacks are relatively expensive, and maintenance is required in the later stage, and the economic benefits are not high

Embodiment Construction

[0013] In order to better understand the technical solutions of the present invention, the following specific examples are described in detail:

[0014] see figure 1 , a large-scale motor installation and adjustment device of the present invention includes an upper panel 1 of the chassis of the motor base frame, a lower panel 2 of the chassis, and a side support panel 3 of the chassis that supports the two, and is arranged on the upper panel of the chassis The base foot plate 4 also includes a first adjustment plate 5 and a second adjustment plate 6 .

[0015] The first adjustment plate 5 is a thick steel plate with a thickness of 55mm, which is welded to the outside of the side support plate of the chassis, and is provided with 4 M30 connecting screw holes. on board 5. The upper part of the second adjusting plate 6 is provided with two adjusting screw holes of equal height, one of which is an M56 screw hole and the other is a Φ65 through hole. M56 adjusting bolts 8 are ins...

Abstract

The invention discloses a large-scale motor installation adjusting device. The large-scale motor installation adjusting device comprises a first adjusting plate and a second adjusting plate, wherein the first adjusting plate is welded on the outer side of an underframe side supporting plate, the first adjusting plate has a connecting screw hole, the second adjusting plate is fixed on the first adjusting plate through a connecting bolt, an adjusting screw hole is formed in the upper portion of the second adjusting plate and right faces the side face of the base foot plate, and an adjusting bolt penetrates through the adjusting screw hole to abut against the side face of the base foot plate. According to the large-scale motor installation adjusting device, horizontal adjustment of a base of a large-scale motor can be realized.

Description

technical field [0001] The invention relates to a large-scale motor installation adjusting device used in the field of motor installation. Background technique [0002] The chassis and the motor body of the extra-large horizontal motor are transported separately. The axis needs to be adjusted during on-site installation. The stator of this type of motor usually weighs four or fifty tons, and some are even larger than seven or eighty tons. The friction force between it and the chassis is usually greater than 60kN. To overcome such a large friction force and control the adjustment accuracy, it is usually necessary to set up an embedded horizontal support seat on the basis of the site, and then act on our motor through a hydraulic jack. The adjustment is realized on the base plate of the machine base. Once the support base is embedded in the foundation, it cannot be disassembled at any time, which affects the layout of the field equipment and also buries a certain hidden safety...
