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
The invention belongs to the hydraulic technique field, be specifically related to a kind of swinging jack control device.
Background technology
Existing swinging jack be Compress Spring by both sides as righting structure, when the load that will lift be not straight-line motion, when the oil cylinder axis need to swing, then by the dilatation of the spring of both sides by way of compensation, to satisfy the servo-actuated requirement of oil cylinder axis.The axial location of oil cylinder initial condition is fixing position, when piston rod end and stressed carrier contact position need to be adjusted, can not meet the demands; Lack simultaneously oil cylinder shaft angle number of degrees value reflection function.
Summary of the invention
The objective of the invention is: provide a kind of both can be in the course of the work, the oil cylinder axis can change with load request, and in when beginning, the swinging jack control device that the position of oil cylinder end can adjust.
The object of the present invention is achieved like this: swinging jack control device, comprise frame, the bottom of frame lower end and an oil cylinder is hinged, the oil cylinder middle part is by stationary fixture captive joint quadrant gear, the frame upper end is fixedly installed bearing cap shim and bearing, place gear wheel shaft in the bearing, gear wheel shaft is fixedly installed the miniature gears that meshes with quadrant gear near an end of quadrant gear, and the other end of gear wheel shaft arranges handwheel.
As a kind of improvement of the present invention, left block and right block also are set on the frame, quadrant gear near the position of right block be fixedly installed one can with the latch of right block locking.Two blocks can be spacing, when this device is not worked, latch inserted in the right block, then can avoid oil cylinder to deflect, and namely has oil cylinder deflection auto-lock function.
As a kind of improvement of the present invention, calibrated disc of captive joint on the described gear wheel shaft, the position near calibrated disc on the gear wheel shaft is flexibly connected a pointer.Pointer remains the upright position under Action of Gravity Field, when oil cylinder axial location generation beat, then drive miniature gears, gear wheel shaft and calibrated disc, and pointer indication scale is oil cylinder axial line angle of inclination.Because the transmitting ratio i=15 of quadrant gear and miniature gears is so this device can more accurately reflect the angle that oil cylinder tilts.
The present invention is designed with the hinged oil cylinder of a bottom and frame, the oil cylinder middle part is designed with a quadrant gear concentric with jointed shaft, be meshed with the miniature gears of other design on frame, when the oil cylinder axis need adjust, rotate as long as then control quadrant gear by rotation hand wheel, gear wheel shaft, can reach the purpose of adjusting the oil cylinder axial location.
The present invention in the course of the work, when the act load movement be not linearly move, the oil cylinder axial line need to change do servo-actuated adjustment the time with the angle of load, this device can satisfy functional requirement; And when the work beginning, can in allowed band, adjust arbitrarily the angle position of oscillating oil cylinder axis.
Description of drawings
Fig. 1 is a kind of structural representation of the present invention.
Fig. 2 is the lateral plan of Fig. 1.
Fig. 3 is that the A of Fig. 1 is to partial view.
The specific embodiment
As shown in Figure 1, 2, 3, swinging jack control device, comprise frame 1, the bottom of frame 1 lower end and an oil cylinder 8 is hinged, oil cylinder 8 middle parts are by stationary fixture 9 captive joint quadrant gears 11, and frame 1 upper end is fixedly installed bearing cap shim 6 and bearing 3, places gear wheel shaft 4 in the bearing 3, gear wheel shaft 4 is fixedly installed the miniature gears 7 that meshes with quadrant gear 11 near an end of quadrant gear 11, and the other end of gear wheel shaft 4 arranges handwheel 12.
Calibrated disc 5 of captive joint on the gear wheel shaft 4, the position near calibrated disc 5 on the gear wheel shaft 4 is flexibly connected a pointer 2.
Claims (3)
