Technical field
The utility model relates to the oil pump of the drg that uses on a kind of hoisting crane, relates in particular to a kind of foot-operated filling pump of braking that is applicable to.
Background technology
On the active travelling wheel of hoisting crane and the transmission shaft between the motor, generally all be provided with drg, when outage, drg is held transmission shaft automatically tightly, and initiatively travelling wheel is out of service thereby make.
In the prior art, normal a kind of power hydraulic pressure block brake, the distance between two relative brake shoes of major control of adopting of the drg of hoisting crane.Under the situation of energising, the push rod of power hydraulic pressure block brake moves up, and promotes lever and screw rod, so promote two brake shoes relatively away from, thereby the power that guarantees motor output passes to initiatively travelling wheel smoothly; During outage, the push rod of power hydraulic pressure block brake moves down, pull lever and screw rod, and then spur two brake shoes near, thereby locking motor and the transmission shaft between the travelling wheel initiatively.
Yet; Mainly there is following deficiency in the power hydraulic pressure block brake of said structure: the main dependence break-make electricity that starts or stops of power hydraulic pressure block brake is realized; The speed of braking can't be regulated along with the height of lifted weight, the weight of lifted weight and the speed that lifted weight moves; The energy disperser and the collision of safe stop that are prone to the hoisting crane termination are strong, and the amplitude of lifted weight swing is bigger, is unfavorable for the accurate shipment of lifted weight.
The utility model content
To the above-mentioned deficiency that exists in the prior art, the utility model provides a kind of and can brake at any time, and the foot-operated filling pump that can adjust at any time of retro-speed.
In order to solve the problems of the technologies described above, the utility model has adopted following technical scheme:
Foot-operated filling pump comprises box body, torque spring, oil cylinder, stretcher, rotating shaft and drive spindle; Said rotating shaft pass box body and with the box body normal-running fit, the cylinder body of said oil cylinder penetrates in the box body, the piston of oil cylinder is positioned at box body and vertical with rotating shaft; Said stretcher is fixed on the cylindrical of rotating shaft and is positioned at outside the box body, and said drive spindle is perpendicular to rotating shaft, and an end of drive spindle is fixed in the rotating shaft, and the other end passes piston and cooperates with piston play; Said torque spring is enclosed within the rotating shaft, and an end of torque spring is fixed on the box body, and the other end is fixed in the rotating shaft; The oil inlet and the oil outlet of said oil cylinder are positioned at outside the box body.
As a kind of preferred version of the utility model, said oil inlet is near box body, and said oil outlet is arranged on the outer end of cylinder body.
As the another kind of preferred version of the utility model, the piston of said oil cylinder is provided with chute along its axial direction, the other end of drive spindle pass chute and with the chute free-running fit.
The beneficial effect of the utility model is: using should be foot-operated during filling pump, the oil outlet of oil cylinder is connected the oil cylinder of drg, through the oil pump capacity of foot feed oil cylinder oil outlet; Thereby the control brake shoe is held the tightness of brake wheel tightly; Realize artificial control brake speed, and retro-speed can adjust at any time, when hoisting crane runs to rail end; Gently step in advance stretcher; Can alleviate the impact force between energy disperser and the safe stop effectively, reduce the amplitude of lifted weight swing, more help the accurate shipment of lifted weight.

Fig. 1 is the structural representation of foot-operated filling pump.
In the accompanying drawing: 1-box body; 2-torque spring; 3-stretcher; 4-rotating shaft; 5-drive spindle; 6-cylinder body; 7-piston; 8-oil inlet; 9-oil outlet; 10-chute; 11-pipe link; 12-oil storage cylinder; 13-deflation hole.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is done to describe in further detail.
As shown in Figure 1, foot-operated filling pump comprises box body 1, torque spring 2, oil cylinder, stretcher 3, rotating shaft 4 and drive spindle 5.Box body 1 is passed in rotating shaft 4, is fixed with bearing at the cylindrical of rotating shaft 4, and rotating shaft 4 is through bearing and box body 1 normal-running fit.The cylinder body 6 of oil cylinder penetrates in the box body 1 and is fixed on the box body 1, and the piston 7 of oil cylinder is positioned at box body 1 and vertical with rotating shaft 4.Stretcher 3 is captiveed joint with the cylindrical of rotating shaft 4 through pipe link 11, and stretcher 3 is welded on the end of pipe link 11, and the other end of pipe link 11 is welded in the rotating shaft 4.Drive spindle 5 is perpendicular to rotating shaft 4, and an end of drive spindle 5 is fixed in the rotating shaft 4, the other end pass piston 7 and with piston 7 free-running fits.Torque spring 2 is enclosed within the rotating shaft 4, and is positioned at outside the box body 1, and an end of torque spring 2 is fixed on the box body 1, and the other end of torque spring 2 is fixed in the rotating shaft 4.The oil inlet 8 and the oil outlet 9 of oil cylinder are positioned at outside the box body 1.
The piston 7 of oil cylinder is provided with chute 10 along its axial direction, the other end of drive spindle 5 pass chute 10 and with chute 10 free-running fits.Make drive spindle 5 in rotating shaft 4 rotating process, the top of drive spindle 5 can promote that piston 7 moves forward or move backward.
Using should be foot-operated during filling pump, and at first the oil outlet 9 with oil cylinder is connected with the oil cylinder of drg, and the oil inlet of oil cylinder is connected with oil storage cylinder 12.Should ride filling pump and be installed in the operator's compartment, and need glancing impact, the operating personal only using foot is stepped on down stretcher 3; Stretcher 3 just drives rotating shaft 4 and rotates, and rotating shaft 4 drives drive spindle 5 and rotates together, and move in chute 10 at the top of drive spindle 5; Driven plunger 7 is pushed ahead simultaneously; Hydraulic oil in the cylinder body 6 is forced out and gets in the oil cylinder of drg, and brake wheel is drawn close and held tightly step by step to two brake shoes that promote on the drg, realizes braking; Hoisting crane is when starting; Only need unclamp stretcher 3, rotating shaft 4 is rotated under the restoring force effect of torque spring 2, and rotating shaft 4 drives drive spindle 5 and rotates together; Drive spindle 5 driven plunger 7 move backward; The in-oil cylinder hydraulic oil of drg turns back in the oil cylinder of foot-operated filling pump, and two brake shoes on the drg are to two side shiftings and break away from brake wheel gradually, and motor-driven initiatively travelling wheel is rotated.
Therefore, use and should ride filling pump, can be through the oil pump capacity of foot feed oil cylinder oil outlet; Thereby the control brake shoe is held the tightness of brake wheel tightly, realize artificial control brake speed, and retro-speed can be adjusted at any time; When hoisting crane runs to rail end, gently step on stretcher in advance, can alleviate the impact force between energy disperser and the safe stop effectively; Reduce the amplitude of lifted weight swing, more help the accurate shipment of lifted weight.
