Abstract
The utility model relates to a braking device for a pumping unit. The braking device for the pumping unit is designed mainly for solving the problem that the braking effect of a manual braking device of an existing pumping unit is poor. The braking device for the pumping unit comprises an electromagnet block brake. The outer end of a brake shaft of the electromagnet block brake is provided with a connecting spanner, and the part, extending out of a U-shaped fork of the connecting spanner, of the brake shaft of the electromagnet block brake is provided with an adjusting nut. The bottom of the connecting spanner is provided with a connecting rod and two pulling rods, wherein the pulling rods are connected through a forward buckle and a backward buckle, the connecting rod is connected with the front ends of the pulling rods, and the back ends of the pulling rods are installed on the lower portion of a manual operating rod which is installed on a brake positioning base. An operating handle is arranged on the top of the manual operating rod, a positioning tooth groove is formed in the brake positioning base, a limiting rod handle is arranged on the top of a limiting rod, teeth at the bottom of the limiting rod are installed inside the positioning tooth groove of the brake positioning base, and the limiting rod handle is installed on the manual operating rod handle. One end of a tension spring is fixed on the limiting rod handle, and the other end of the tension spring is fixed on the manual operating rod. The braking device for the pumping unit has the advantage of being good in braking effect.
Description
Technical field:
The utility model relates to employed brake device on a kind of pumping unit.
Background technique:
The braking device of pumping unit all comprises electrodynamic braking and two kinds of forms of hand brake, electrodynamic braking is that electromagnetic blocked brake is installed in the brake wheel place, is the braking of brake cable formula but at present the manual braking device of pumping unit adopts, because brake cable has elastic force, so brake failure is quick, braking effect is bad.
Summary of the invention:
It is sensitive that technical problem to be solved in the utility model provides a kind of manual brake, the used for oil extractor brake device that braking effect is good.
Above-mentioned purpose is achieved in that it comprises electromagnetic blocked brake, it is characterized in that: we establish the connection spanner in electromagnetic blocked brake brake axle outer end, connect spanner and be provided with the U-shaped fork, the electromagnetic blocked brake brake axle stretches out from the U-shaped fork that connects spanner, on the electromagnetic blocked brake brake axle of extension adjusting nut is housed, connect the spanner bottom and be fixed with connecting rod, also comprise two pull bars, two pull bars link together with positive left-hand thread nut, the lower end of connecting rod be connected the front end of a pull bar and connect by bearing pin, the rear end of second pull bar is contained in the bottom of manual joystick by bearing pin, the bottom of manual joystick is contained on the brake positioning seat by bearing pin, the top of manual joystick is Joystick, have several location teeth groove on the brake positioning seat, the top limited location bar handle of position-limited lever, the tooth that adapts with the locating tooth groove shape of brake on the positioning seat is arranged at the bottom of position-limited lever, be contained in bottom the position-limited lever in the location teeth groove on the brake positioning seat, the bottom of position-limited lever handle is contained on the manual joystick handle by bearing pin, also comprise extension spring, one end of extension spring is fixed on the position-limited lever handle, and the other end is fixed on the manual joystick.
The utility model has the advantages that: because this device is that pull bar and connecting rod link together, connecting rod is connected with manual joystick, belongs to hard connection, so brake is sensitive, effective; In addition, because two connecting rods are to link together by positive left-hand thread nut, so the length of connecting rod is adjustable, easy for installation.
Description of drawings:
Accompanying drawing 1 is structural representation of the present utility model.
Embodiment:
With reference to accompanying drawing, it comprises electromagnetic blocked brake 1, establish connection spanner 2 in electromagnetic blocked brake brake axle 3 outer ends, connect spanner and be provided with the U-shaped fork, the electromagnetic blocked brake brake axle stretches out from the U-shaped fork that connects spanner, on the electromagnetic blocked brake brake axle of extension adjusting nut is housed, connect the spanner bottom and be fixed with connecting rod 4, also comprise two pull bars 5, two pull bars link together with positive left-hand thread nut 6, the lower end of connecting rod 4 be connected the front end of a pull bar 5 and connect by bearing pin, the rear end of second pull bar is contained in the bottom of manual joystick 8 by bearing pin, the bottom of manual joystick is contained on the brake positioning seat 7 by bearing pin, the top of manual joystick is Joystick 9, have several location teeth groove 13 on the brake positioning seat, the top limited location bar handle 10 of position-limited lever 12, the tooth that adapts with the locating tooth groove shape of brake on the positioning seat is arranged at the bottom of position-limited lever, be contained in bottom the position-limited lever in the location teeth groove on the brake positioning seat, the bottom of position-limited lever handle is contained on the manual joystick handle by bearing pin, also comprise extension spring 11, one end of extension spring is fixed on the position-limited lever handle, and the other end is fixed on the manual joystick.
