Problems solved by technology

The axis position of the initial state of the oil cylinder is a fixed position. When the contact position between the end of the piston rod and the force carrier needs to be adjusted, it cannot meet the requirements; at the same time, it lacks the value reflection function of the axis inclination angle of the oil cylinder

Embodiment Construction

[0012] Such as figure 1 , 2 3, the swing jack control device includes a frame 1. The lower end of the frame 1 is hingedly connected to the bottom of an oil cylinder 8. The middle of the oil cylinder 8 is fixedly connected to the sector gear 11 through a fixing fixture 9, and the upper end of the frame 1 is fixedly provided with a bearing Cover 6 and bearing 3. A gear shaft 4 is inserted in the bearing 3. One end of the gear shaft 4 close to the sector gear 11 is fixedly provided with a pinion 7 meshing with the sector gear 11, and the other end of the gear shaft 4 is provided with a hand wheel 12.

[0013] The frame 1 is also provided with a left block 10 and a right block 14, and a pin 13 that can be locked with the right block 14 is fixedly arranged at a position of the sector gear 11 close to the right block 14.

[0014] A dial 5 is fixedly connected to the gear shaft 4, and a pointer 2 is movably connected to the gear shaft 4 at a position close to the dial 5.

Abstract

The invention belongs to the technical field of hydraulic pressure, and in particular relates to a swinging jack control device. The device comprises a frame, the lower end of the frame is hinged with the bottom of a cylinder, the middle part of the cylinder is fixedly connected with a fan-shaped gear through a fixed clamp, a bearing cover and a bearing are fixedly arranged at the upper end of the frame, a gear shaft passes through the bearing, a pinion engaged with the fan-shaped gear is fixedly arranged at one end of the gear shaft close to the fan-shaped gear, and a hand wheel is arranged at the other end of the gear shaft. In the working process, when the motion of a hoisted load is not linear motion and the axis of the cylinder needs to be adjusted together with the angle change of the load, the device can meet the function requirements; and the angle position of the axis of the swinging cylinder can be randomly adjusted in an allowed range when the operation starts.

Description

Technical field [0001] The invention belongs to the technical field of hydraulics, and particularly relates to a swing jack control device. Background technique [0002] The existing swing jack uses compression springs on both sides as the centralizing structure. When the load to be lifted does not move linearly and the cylinder axis needs to swing, the expansion and contraction deformation of the springs on both sides is used as compensation to meet the cylinder axis. Follow-up requirements. The axis position of the cylinder in the initial state is a fixed position. When the contact position between the end of the piston rod and the force carrier needs to be adjusted, it cannot meet the requirements; at the same time, the cylinder axis tilt angle value reflection function is lacking. Summary of the invention [0003] The purpose of the present invention is to provide a swing jack control device that can change the axis of the oil cylinder with load requirements during the workin...
