Embodiment Construction

[0029] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0030] see figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 .

[0031] A triple safety device for auxiliary braking of a beam pumping unit includes a starting mechanism 29, an intermediate transmission mechanism, a first safety mechanism, a second safety mechanism and a third safety mechanism.

[0032] The starting mechanism 29 includes a bracket 23, a sleeve pipe 20, a bearing seat 18, a bearing, a drive shaft 22, a bolt transmission part and a manual rotating part. The lower part of the bracket 23 is welded on the pumping unit base 16, and the sleeve pipe 20 and the bearing seat 18 are connected in sequence and welded on the top of the bracket 23. In order to ensure the firmness of the bracket 23, the bracket 23 is welded by steel plates. Drive shaft 22 is installed on the bearing seat 18 by bearing, and the front end of dr...

Abstract

The invention discloses an auxiliary brake triple-safety device for a beam-pumping unit. The auxiliary brake triple-safety device comprises a starting mechanism, an intermediate transfer mechanism, afirst safety mechanism, a second safety mechanism and a third safety mechanism. The starting mechanism comprises a support, a sleeve, a bearing seat, a bearing, a driving shaft, a bolt transmission piece and a manual rotating piece. The first safety mechanism adopts a stop-pin-type structure. The intermediate transfer mechanism comprises a horizontal pull rod, a reversing supporting seat and a vertical pull rod which are connected sequentially. The second safety mechanism comprises a tooth disc, took disk teeth, a brake plate, a brake plate engage switch and a brake plate shaft, wherein the brake plate engage switch and the brake plate shaft are matched with the took disk teeth. The third safety mechanism adopts a locking-bolt-type structure. The auxiliary brake has triple safety, so thatthe car sliding phenomenon is eradicated fundamentally, and it is guaranteed that nothing falls during braking; operation is easy and convenient, any position can be locked and opened; the personal safety of an operator is fully guaranteed; and the process is stationary, and the time and labor are saved.

Description

technical field [0001] The invention relates to the technical field of oil field mechanical braking, in particular to a triple safety device for auxiliary braking of a beam pumping unit. Background technique [0002] Existing brakes mainly include two types of external embracing type and internal tensioning type, all of which utilize friction pairs to realize the braking of the pumping unit. With the increase of the service life, the normal wear and tear of the brake friction pair and the brake wheel, the deformation of the brake linkage mechanism, etc., reduce the braking torque; the operator stops the pumping unit during the construction work, and only relies on the conventional brake device for braking During the operation of the pumping unit, the vibration of the pumping unit due to the change of the load of the oil well, the workover operation, the maintenance of the pumping unit, the replacement of the crank pin assembly, etc., makes the friction pair of the pumping un...
