Embodiment 1

[0021] Such as figure 1 , figure 2 with Figure 4 Commonly shown, figure 1 The left direction of the cutting head shown in the figure represents the rear, and the right direction represents the front. A braking device for a pumping unit includes a brake wheel 16 and a main brake system for braking the brake wheel 16. The main brake system includes sequentially Connected main brake lever 1, main brake seat 2, first pull rod 7, first crank arm 8, second pull rod 11, cam pull plate 12, brake shoe 19, the main brake lever 1 is hinged on the main brake seat 2 , the first crank arm 8 is hinged on the base 17 of the pumping unit through the third rotating shaft 22, and the movable convex teeth on the main brake lever 1 mesh with the rows of teeth on the main brake seat 2.

[0022] The oil pumping unit brake device also includes a secondary brake system for preventing the brake wheel 16 from slipping. A matching safety tooth plate 14, the safety tooth plate 14 is hinged on the ...

Embodiment 2

[0027] Such as figure 1 As shown, a pumping unit brake device, its structure is basically the same as that of Embodiment 1, the difference is that a stopper for limiting the position of the auxiliary brake lever 3 is provided between the auxiliary brake seat 4 and the auxiliary brake lever 3 A safety locking mechanism, the safety locking mechanism includes at least one safety tooth groove 6 arranged on the auxiliary brake seat 4 , and the safety tooth groove 6 is adapted to the movable convex tooth of the auxiliary brake lever 3 .

[0028] The safety locking mechanism may also include several pin holes arranged on the auxiliary brake seat 4 , and a safety pin is arranged between the auxiliary brake seat 4 and the auxiliary brake lever 3 .

[0029] When in use, after the secondary braking system in Embodiment 1 finally locks the brake wheel 16, the safety tooth plate 14 in the secondary braking system meshes with the gear plate portion of the braking wheel 16. When restarting ...

Embodiment 3

[0031] Such as figure 1 , figure 2 with image 3 Commonly shown, a pumping unit braking device, its structure is basically the same as the second embodiment, the difference is that the outer surface of the brake wheel and the inner surface of the brake shoe frictionally connected.

[0032] Operate the main braking system according to Embodiment 1. At this time, the cam pull plate 12 will give the spring on the lower end of the brake shoe 19 connected thereto an external expansion force, so that the inner surface of the brake shoe 19 will be in contact with the outer surface of the brake wheel 16. Friction is generated, and then the brake wheel 16 stops rotating. At this time, the movable convex teeth on the bottom of the main brake lever 1 are meshed with the teeth on the main brake seat 2 to prevent the main brake lever 1 from sliding after braking, so that the braking action is completed. This way is external braking.

Abstract

The invention relates to a brake device of a pumping unit. The brake device of the pumping unit comprises a brake wheel, a brake system for braking the brake wheel, and an assistant brake system for preventing the brake wheel from sliding. The assistant brake system comprises a fluted disc part arranged on the brake wheel and a safety gear plate matched with the fluted disc part, and the safety gear plate is hinged on a shell of a reducer through a first rotating shaft and comprises a connecting rod drive mechanism which is used for driving the safety gear plate to be connected and disconnected with the fluted disc. The brake device of the pumping unit has the beneficial effects of being in remote operation, safe and reliable, reliable in brake, convenient to use and simple to operate, and being suitable for pumping unit braking situations.

Description

technical field [0001] The invention relates to a braking device for an oil pumping unit. Background technique [0002] Liangyou pumping unit is currently the most widely used pumping unit in major oil fields in China, and a brake wheel is installed on the input shaft of the reducer of the pumping unit. There are two types of brakes, which are divided into external brakes and internal expansion brakes. The external brakes rely on the friction between the brake shoe and the outer surface of the brake wheel, and the internal expansion brakes rely on the brake shoe and the inner surface of the brake wheel. friction braking. Such as Image 6 As shown, in order to prevent the car from slipping due to insufficient braking force, a dovetail groove 24 is formed on one side of the outer surface of the brake wheel 23, and the hook 25 hinged on the reducer housing 26 is put into the dovetail groove 24. Effectively prevent the brake wheel 23 from rotating. The shortcoming of this str...
