Abstract
The utility model discloses a brake locking device of an oil pumping unit. The problem that the existing brake device has potential safety hazard is solved. The brake locking device is characterized in that a brake hub (1) is provided with six square teeth outside, a brake lock bracket (2) is fixed on a speed reducer, a brake lock slider (3) is slidingly connected in the brake lock bracket (2), the upper end of the brake lock slider (3) is matched with the square teeth, the lower end of the brake lock slider (3) is hinged with the right end of a connecting rod (4), the connecting rod (4) is hinged with the speed reducer, a strip hole is transversely formed in the left part of the connecting rod (4), and a pin shaft connected with a brake pull rod is arranged in the strip hole. The brake locking device of the oil pumping unit has the features of security and reliability.
Description
Technical field:
The utility model relates to a kind of oil-field oil pumper braking device, especially pumping unit brake locking device.
Background technique:
Adopt the field in the oil field, beam pumping unit is the important lifting equipment in ground.When maintenance,, need on the oil pump speed reducer output shaft, braking device be installed in order to guarantee safety.And existing braking device is because there is the problem of hidden danger in reasons in structure, and when the braking force of braking device during less than the gravity of equilibrium block, under the effect of equilibrium block gravity, pumping unit rotates, thereby causes machinery and human injury.
The model utility content:
In order to solve the problem that there is hidden danger in existing braking device.The utility model provides a kind of pumping unit brake locking device.This pumping unit brake locking device has safe and reliable characteristics.
The technical solution of the utility model is: this pumping unit brake locking device comprises brake hub, brake lock, brake lock slide bar and connecting rod.Brake hub has 6 square teeth outward, the brake lock is fixed on the retarder, brake lock slide bar is slidingly connected in the brake lock, match with square tooth in brake lock slide bar upper end, brake lock slide bar lower end hinge is connected the connecting rod right-hand member, connecting rod link is connected on the retarder, and the connecting rod left part laterally has strip hole, and the bearing pin that is connected on the bracket arm is arranged in the strip hole.
The utlity model has following beneficial effect: this pumping unit brake locking device is owing to adopt brake hub that 6 square teeth are arranged outward, the brake lock is fixed on the retarder, brake lock slide bar is slidingly connected in the brake lock, match with square tooth in brake lock slide bar upper end, brake lock slide bar lower end hinge is connected the connecting rod right-hand member, connecting rod link is connected on the retarder, and the connecting rod left part laterally has strip hole, and optimizing structure of the bearing pin that is connected on the bracket arm arranged in the strip hole.Utilize the outer square tooth of brake lock slide bar and brake hub to cooperate, improve Security.This pumping unit brake locking device has safe and reliable characteristics thus.
Description of drawings:
Accompanying drawing 1 is the utility model structural representation.
1-brake hub among the figure, the 2-lock that brakes, 3-brake lock slide bar, 4-connecting rod.
Embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing:
As shown in the figure, this pumping unit brake locking device comprises brake hub 1, brake lock 2, brake lock slide bar 3 and connecting rod 4.6 square teeth are arranged outside the brake hub 1, brake lock 2 is fixed on the retarder, brake lock slide bar 3 is slidingly connected in the brake lock 2, match with square tooth in brake lock slide bar 3 upper ends, brake lock slide bar 3 lower end hinges are connected connecting rod 4 right-hand members, connecting rod 4 hinges are connected on the retarder, and connecting rod 4 left parts laterally have strip hole, and the bearing pin that is connected on the bracket arm is arranged in the strip hole.
Working principle:
During the pulling bracket arm, bracket arm is advanced downwards, bracket arm moves down by bearing pin drivening rod 4 left ends, right-hand member moves up, and connecting rod 4 promotes brake lock slide bars 3 and moves up, and brake lock slide bar 3 upper tips enter between the outer square tooth of brake hub 1, thereby lock brake hub 1, when the braking force of brake hub 1 gravity less than equilibrium block, pumping unit can not rotate yet, and then improves Security.
Claims (1)
