the supporting table and the base are arranged in parallel, adjusting screws with the same number as the cylinders are vertically arranged on the bottom surface of the supporting table, the adjusting screws are of rod-shaped structures with threads on the outer surfaces, adjusting nuts are sleeved on the outer walls of the adjusting screws, the adjusting nuts are in threaded connection with the adjusting screws, one end surfaces of the adjusting screws are fixedly connected with the supporting table, and the other ends of the adjusting screws penetrate through the plane bearing and are inserted into the cylinders;
the base bottom is provided with the gyro wheel mechanism more than two sets of, gyro wheel mechanism includes wheel, center pin, the center pin is established in the base bottom, the center pin both ends are provided with the wheel respectively.
Preferably, the outer surface of the adjusting nut is provided with a knurled knurl. The arrangement can prevent the adjusting nut from slipping during rotation and increase the friction force.
The invention has the beneficial effects that:
the lifting trolley for disassembling and assembling the horizontal motor in the narrow space, provided by the invention, has a small volume, can enter the narrow space which cannot be entered by a common hydraulic platform, and is convenient for workers to disassemble and assemble the motor; the support table provided by the invention provides a working platform with a motor stably assembled and disassembled, so that a worker can work more safely and conveniently.

Detailed Description
In order to explain the technical content, the achieved objects and the effects of the present invention in detail, the following description is made in conjunction with the embodiments and the accompanying drawings.
Example 1
Referring to fig. 1, the invention provides a horizontal motor dismounting lifting trolley in a narrow space, which comprises a supporting platform 1, an adjusting screw 2, a base 6 and an adjusting nut 3, wherein the base 6 is horizontally arranged, more than three cylinders 5 are vertically arranged on the base 6, the cylinders 5 are in axial hollow cylindrical structures, one end face of each cylinder 5 is fixedly connected with the base 6, and the outer wall of the other end of each cylinder is sleeved with a plane bearing 4; the supporting table 1 and the base 6 are arranged in parallel, the bottom surface of the supporting table 1 is vertically provided with adjusting screws 2 with the same number as that of the cylinders 5, the adjusting screws 2 are of rod-shaped structures with threads on the outer surfaces, adjusting nuts 3 are sleeved on the outer walls of the adjusting screws 2, the adjusting nuts 3 are in threaded connection with the adjusting screws 2, one end surface of each adjusting screw 2 is fixedly connected with the supporting table 1, and the other end of each adjusting screw 2 penetrates through a plane bearing 4 and is inserted into the cylinder 5; the base 6 bottom is provided with the gyro wheel mechanism more than two sets of, gyro wheel mechanism includes wheel 7, center pin 9 is established in the base bottom, center pin 9 both ends are provided with wheel 7 respectively.
When the motor 8 is detached, the invention is pushed to the position below the motor 8 of the machining center, the adjusting nut 3 is rotated to move downwards as shown in figure 1 until the bottom end of the adjusting nut 3 is abutted against the plane bearing 4, at this time, the adjusting nut 3 can not move downwards because of the plane bearing 4, the plane bearing 4 limits the adjusting nut 3 to move downwards, but the plane bearing 4 does not limit the adjusting nut 3 to rotate around the axis, so the adjusting nut 3 can still rotate continuously, because the adjusting nut 3 is in threaded connection with the adjusting screw rod 2, the adjusting screw rod 2 is lifted upwards under the action of the rotation of the adjusting nut 3, so the height of the pallet 1 can be adjusted through the adjusting nut 3, the pallet 1 effectively supports the motor 8 from the bottom, a worker can detach the screw of the motor 8 under no pressure, and after the screw of the motor 8 is detached, the motor 8 is easily placed on the pallet, the motor 8 can be taken out for maintenance and replacement as long as the invention is pushed. And when motor 8 installation meeting machining center, can hang motor 8 on the saddle 1, then push into the mounted position motor 8, rotate adjusting nut 3 for motor 8 is unanimous with the mounted position, and the workman penetrates the screw and screws up the installation process that can accomplish the motor.
Therefore, the working process shows that the motor has small structure volume, is flexible and convenient, can enter a narrow space, is convenient for the disassembly and the assembly of the motor, is convenient and quick, and saves manpower and material resources; and it still provides a motor dismouting steady work platform for it is safer convenient when the workman works.
