Technical field:

The present invention relates to oil-well rig equipment technical field, in particular to a kind of drilling machine, workover rig winch band brake help Power device.

Background technique:

Existing drilling machine, workover rig winch band brake system are mainly by brake actuating mechanism, connecting lever, connecting rod and brake lever group At when driller personnel, which move brake lever, carries out brake operation, brake lever drives connecting rod, connecting lever to act together, makes brake actuating mechanism Brake hubs are tightly embraced, to realize the brake of drilling machine, workover rig winch.

But since the transmission chain of brake lever, connecting rod, connecting lever, executing agency's composition is all rigid connection, when carrying out brake behaviour When making, executing agency can generate very big frictional force during holding brake hubs tightly, to cause to entire transmission chain very big Impact and shake, this impact and shake are transmitted on the brake lever of driller's personnel control by transmission chain.When emergency brake, driller Personnel need two it is hand-tight it is tight hold brake lever to buffer this impact and shake, not only large labor intensity, but will give driller people Member brings obviously sense of discomfort, causes security risk to field operation.

Summary of the invention:

The technical problem to be solved in the present invention is to provide a kind of drilling machine, workover rig winch band brake power assisting device, the dresses It sets to realize and effective buffering can be provided to brake system, thoroughly eliminate the impact caused by driller personnel and shake, brake Motion action is light, reduces the labor intensity of operator, improves the safety of operation, and manufacturing cost is low, structurally reasonable.Overcome Driller personnel very big impact and shake can be passed to when existing drilling machine, the brake of workover rig winch band brake mechanism, to department Brill personnel bring obviously sense of discomfort, and the deficiency of security risk is caused to field operation.

The technical solution used in the present invention is: a kind of drilling machine, workover rig winch band brake power assisting device, including stop , connecting rod, connecting lever, executing agency and brake hubs, brake lever be connected with connecting rod, connecting lever is connected with executing agency；It further include power-assisted Fluid cylinder and support, power-assisted fluid cylinder are arranged on the support, and power-assisted fluid cylinder each side has a piston, power-assisted fluid cylinder left hand piston Piston rod be connected with connecting lever, the piston rod of power-assisted fluid cylinder right hand piston is connected with connecting rod, and power-assisted fluid cylinder has an oil inlet Pipe and an oil return pipe are all connected to integrated hydraulic station.

Support welds on a chassis.

The beneficial effects of the present invention are: the present invention realizes can provide effective buffering to brake system, thoroughly eliminate Impact and shake caused by driller personnel, brake operation is light, reduces the labor intensity of operator, improves operation Safety, manufacturing cost is low, structurally reasonable.

Detailed description of the invention:

The present invention will be further described in detail with reference to the accompanying drawings and detailed description.

Fig. 1 is the structural diagram of the present invention.

Specific embodiment:

As shown in Figure 1, a kind of drilling machine, workover rig winch band brake power assisting device, including brake lever 3, connecting rod 4, connecting lever 5, Executing agency 6 and brake hubs 7, brake lever 3 are connected with connecting rod 4, and connecting lever 5 is connected with executing agency 6；It further include 1 He of power-assisted fluid cylinder Support 2, power-assisted fluid cylinder 1 are arranged on support 2, and power-assisted fluid cylinder 1 each side has a piston, 1 left hand piston of power-assisted fluid cylinder Piston rod be connected with connecting lever 5, the piston rod of 1 right hand piston of power-assisted fluid cylinder is connected with connecting rod 4, and power-assisted fluid cylinder 1 has one Oil inlet pipe and an oil return pipe are all connected to integrated hydraulic station.

Support 2 welds on a chassis.

In operation process, when driller personnel move brake lever 3, brake lever 3 drives connecting rod 4 to act, and connecting rod 4 pushes power-assisted oil 1 right hand piston of cylinder acts to the left, and 1 internal hydraulic pressure oil keeper of power-assisted fluid cylinder is pushed 1 left hand piston of power-assisted fluid cylinder to the left by pressure at this time Movement, so that connecting lever 5, executing agency 6 be pushed to complete entire brake；When driller personnel unclamp brake lever 3, power-assisted fluid cylinder 1 Right hand piston is since the effect of hydraulic oil is turned right movement, and left hand piston recycles automatically at this time, and executing agency 6 divides with brake hubs 7 From brake terminates.

It is understood that being merely to illustrate the present invention above with respect to specific descriptions of the invention and being not limited to this Technical solution described in inventive embodiments, those skilled in the art should understand that, still the present invention can be carried out Modification or equivalent replacement, to reach identical technical effect；As long as meet use needs, all protection scope of the present invention it It is interior.
