Description
Technical field
The utility model relates to a kind of pumping unit hydraulic brake device.
Background technique
Now pumping unit is using mechanical pull-rod type brake in a large number, but has safety problem, brake failure often occurs, the phenomenon such as insecure, the brake stroke debug difficulties of braking.Its deficiency is:
1, brake was lost efficacy
What oil pumping unit brake was used is the mechanical friction type braking device.When the conditions such as pit shaft internal pressure, fluid column change, the horse head polished rod load changes thereupon, and horse head has the trend of motion up or down.Now, keep the crank potential energy under relative static conditions will be converted into kinetic energy and move.The accident of energy discharges the generation that will damage accident.
2, the skidding design is unreasonable
Former braking device is mainly to realize by the length of adjusting brake connecting rod and the opening and closing degree of brake hub when adjusting braking, the connection of brake connecting rod is by being threaded, impact due to external factors such as burn into weathering, connecting rod screw connection point and commutator often, in rust death situation state, make to adjust very difficult.In addition, the opening and closing degree of brake hub is that when nut is tightened to a certain degree, spring follows the string by the adjusting nut adjustment, and brake hub opening and closing degree diminishes, and braking force reduces greatly.
Therefore, must undergo technological transformation to former brake system, to improve its Security and operability.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of pumping unit hydraulic brake device.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: the pumping unit hydraulic brake device comprises liquid stop handle, oil can, brake master cylinder, break, high-pressure oil pipe, brake disc and input shaft;
Oil can is connected with brake master cylinder, and the liquid handle of stopping is connected with the piston of brake master cylinder by connecting rod;
Break comprises wheel cylinder, regulator, brake shoe, friction plate, return spring; Brake shoe is arc, and two brake shoes and break are hinged, and an end of two brake shoes is connected with the piston rod of wheel cylinder, and the other end is connected with regulator, and return spring connects the two ends of brake shoe; On two brake shoes, friction plate all is housed;
Break is arranged in brake disc; Brake disc is connected with the input axle key;
Brake master cylinder is connected with wheel cylinder by high-pressure oil pipe.
The beneficial effects of the utility model are:
Transform traditional mechanical brake as water brake, the braking force that produces strengthens and is stable, simple in structure, easy to manufacture, be convenient to decompose carry, installation and maintenance, Safety performance improves.
The accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is the utility model pumping unit hydraulic brake device embodiment's the liquid handle arrangement schematic diagram of stopping.
Fig. 2 is the utility model pumping unit hydraulic brake device embodiment's brake structural schematic diagram.
The 1-liquid handle of stopping, 2-oil can, 3-brake master cylinder, 4-high-pressure oil pipe, 5-wheel cylinder, 6-brake shoe, 7-friction plate, 8-return spring, 9-regulator, 10-brake disc, 11-input shaft, 12-bolt.
Embodiment
The pumping unit hydraulic brake device, be comprised of stop handle, oil can, brake master cylinder, break, high-pressure oil pipe, brake disc and input shaft of liquid.
In Fig. 1, oil can 2 is connected with brake master cylinder 3, and the liquid handle 1 of stopping is connected with the piston of brake master cylinder 3 by connecting rod.
In Fig. 2, break is comprised of wheel cylinder 5, brake shoe 6, friction plate 7, return spring 8, regulator 9.The chassis of break is circular.Brake shoe 6 is arc, and the chassis of two brake shoes and break is hinged, and an end of two brake shoes is connected with the piston rod of wheel cylinder 5, and the other end is connected with regulator 9, and return spring 8 connects the two ends of brake shoe.On two brake shoes, friction plate 7 all is housed.
Break is arranged in brake disc 10.Brake disc 10 is connected with input shaft 11 by key.
During installation, break is fixed on speed reducer with bolt 12, the input shaft 11 of speed reducer stretches out through the center hole of break.Brake disc relies on axle key to be fixed on input shaft.The friction plate of break contacts generation frictional force and is braked with the inwall of brake disc.
Working principle:
In the stop bottom of handle of liquid, support is housed, the piston by connecting rod and brake master cylinder is connected, and break is fixed on speed reducer, and the input shaft of speed reducer stretches out through the break center hole.Brake disc relies on axle key to be fixed on input shaft, and along with input shaft rotates, break and brake disc are combined, and the gap length between brake shoe and brake disc is adjusted by regulator.
Hold the hydrodynamic handle of stopping during operation and promote forward, the piston that connecting rod of bottom drives in brake master cylinder moves backward, and the hydraulic oil in oil can is sucked in brake master cylinder.Then pull back the liquid handle of stopping, the connecting rod of bottom promotes the piston advances forward of brake master cylinder, and the hydraulic oil in cylinder is pressed to wheel cylinder by high-pressure oil pipe.When the oil pressure in wheel cylinder is greater than spring to the pulling force of brake shoe, the piston of wheel cylinder promotes brake shoe to both sides, when friction plate is encountered the inwall of rolling disc, start to produce frictional force between friction plate and rolling disc, stops input shaft of pumping unit to rotate.Hold power larger, braking force is also larger; While getting off the brakes, unclamp the liquid handle of stopping, the oil pressure in brake master cylinder disappears, and due to the effect of return spring, pulls brake shoe to keep in the center, and fricative braking force disappears.
Above-described the utility model mode of execution, do not form the restriction to the utility model protection domain.Any modification of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in claim protection domain of the present utility model.
