Description

Technical Field

[0001] The present application relates to the technical field of jacks, and specifically discloses a jack for motor maintenance. Background Art

[0002] A wheel jack is a jack equipped with rollers. The rollers installed at the bottom make the jack easier to move and save labor. Wheel jacks are usually hydraulic jacking structures. Manual reciprocating pressure on the handle drives the hydraulic pump to drive the driving arm of the jacking mechanism to raise and lower it.

[0003] When the wheel jack is used in the process of motor maintenance for the vibrating screen, because the overall volume of the vibrating screen is large, and the motor of the vibrating screen is installed in the air, about 50 cm from the ground, and there is no lifting device above it.

[0004] When lifting a motor, an ordinary wheel jack can only support the motor through the lifting plate and cannot lift the motor to the required height.

[0005] Therefore, in view of this, the inventor provides a motor maintenance jack to solve the above problems. Utility Model Content

[0006] The purpose of the utility model is to solve the problem that the traditional wheel jack can only support the motor through the lifting plate during the maintenance of the motor of the vibrating screen, but cannot lift the motor to the required height.

[0007] In order to achieve the above-mentioned purpose, the basic scheme of the present invention provides a jack for motor maintenance, including a frame, a lifting arm rotatably connected to the inner side of the frame, a slewing arm arranged on the inner side of one end of the frame and hinged to the end of the lifting arm, a hydraulic mechanism arranged in the frame for lifting the slewing arm, a driving member arranged at the other end of the frame and used to drive the hydraulic mechanism and rollers rotatably connected to the bottom of both ends of the frame, and also including a lifting plate and a support member, the lifting plate is fixedly connected to the end of the slewing arm and coaxially opened with a through hole, the bottom of the lifting plate is fixedly connected to a resistance plate, and the support member includes a sliding rod that can be slidably connected to the through hole and abutted against the resistance plate, and an arc rod fixedly connected to the top of the sliding rod and used to support the outer wall of the motor.

[0008] Furthermore, the sliding rod can rotate in the through hole.

[0009] Furthermore, the widths of both sides of the arc-shaped rod are greater than the width of the motor.

[0010] Furthermore, a handle is rotatably connected to one end of the frame close to the driving member.

[0011] Furthermore, the driving member includes a connecting rod for driving the hydraulic mechanism and a pressure rod detachably connected to the connecting rod.

[0012] Furthermore, the end of the connecting rod is located on the inner side of the same end of the frame.

[0013] The principle and effect of this solution are:

[0014] Compared with the prior art, the utility model has a jacking plate installed on the slewing arm, and a support member is installed through the jacking plate, so that the motor can be placed on the arc rod in the support member. During the jacking process of the motor, one operator holds one end of the motor and cooperates with the arc rod to support the motor, and the other operator drives the hydraulic structure to jack up the motor, and the support member plays a role of further lifting the motor. In the process of gradually screwing in the bolts between the motor and the vibrating screen, the arc rod can play an auxiliary supporting role. At the same time, when disassembling the motor, it can also support the motor in the process of gradually screwing out the bolts, which solves the problem that the traditional wheel jack can only support the motor through the jacking plate during the inspection and maintenance of the vibrating screen motor and cannot lift the motor to the required height.
