Abstract
The utility model relates to an oil field workover rig, in particular to an automatic braking system for a workover rig with an uncontrolled braking handle. An L-shaped braking handle fixed clamp seat is fixed on a workover rig braking handle and connected with an L-shaped accident-preventing braking handle, an L-shaped braking handle supporting spring and a supporting force adjusting button are mounted on the L-shaped accident-preventing braking handle, the lower end of the L-shaped accident-preventing braking handle contacts with a switch button on a normally-closed switch, a button reset spring is mounted in the normally-closed switch, a braking air cylinder is connected on a braking chassis, a braking air cylinder push rod is mounted in the braking air cylinder and connected with an auxiliary braking control handle, and the auxiliary braking control handle is connected with a braking shaft. By the aid of the automatic braking system for the workover rig with the uncontrolled braking handle, automatic braking of the workover rig is realized when a braking handle operator loses operating capability of a braking handle in case of accidents, and the defect in a braking protecting device when the braking handle is out of control in case of that existing workover rigs are not controlled by operators in accidents is overcome.
Description
Technical field:
The utility model relates to a kind of oil well equipment, particularly a kind of well servicing equipment brake lever autobrake system out of control.
Background technique:
The brake protection of existing well servicing equipment only has colliding crown block brake protective system, occurs the unexpected braking protection device that loses when brake lever is controlled when but not controlling hand and controlling.
The model utility content:
The technical problems to be solved in the utility model is to provide a kind of well servicing equipment brake lever autobrake system out of control, this device realized when controlling the brake lever personnel once occur fortuitous event lose to well servicing equipment after the ability of controlling of brake lever can automatic brake tight braking.It is unexpected that the deficiency that loses the braking protection device when brake lever is controlled appear when having overcome existing well servicing equipment and not controlling hand and control.
technical solution adopted in the utility model is: a kind of well servicing equipment brake lever autobrake system out of control comprises well servicing equipment brake lever and brake axle, be fixed with L shaped brake lever Fixing clamp-seat on the well servicing equipment brake lever, L shaped brake lever Fixing clamp-seat connects anti-unexpected L shaped brake lever, L shaped brake lever is installed on anti-unexpected L shaped brake lever holds up spring and picking-up power adjusting button, switch button under anti-unexpected L shaped brake lever on the end in contact normally closed switch, the push-button reset spring is housed in normally closed switch, brake is connected with brake cylinder on the chassis, the brake cylinder push rod is installed in brake cylinder, the brake cylinder push rod connects the auxiliary brake control handle, the auxiliary brake control handle connects brake axle, gas source inlet on normally closed switch connects and resets and enable air outlet II on switch, reset and enable and have primary air inlet on switch, the air outlet I that resets and enable on switch connects the rapid escape valve II, the rapid escape valve II connects the suction port that resets on brake cylinder, brake suction port on brake cylinder connects the rapid escape valve I, the rapid escape valve I connects the source of the gas outlet on normally closed switch.
The beneficial effects of the utility model are: the utility model has been owing to having adopted on the well servicing equipment brake lever mode that connects anti-unexpected L shaped brake lever and brake cylinder is installed on brake axle, thereby has when controlling the brake lever personnel once fortuitous event occurs and lose function to well servicing equipment energy automatic brake tight braking after the ability of controlling of brake lever; In addition, the utlity model has and install that cost is low, technique simply and not affects the advantage of any other performance of drilling and repairing well equipment additional.
Description of drawings:
The utility model is described in more detail below in conjunction with the drawings and specific embodiments.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of brake cylinder.
Fig. 3 is gas control schematic diagram of the present utility model.
Embodiment:
as Fig. 1, Fig. 2, shown in Figure 3, a kind of well servicing equipment brake lever autobrake system out of control comprises well servicing equipment brake lever 1 and brake axle 16, be fixed with L shaped brake lever Fixing clamp-seat 5 on well servicing equipment brake lever 1, L shaped brake lever Fixing clamp-seat 5 connects anti-unexpected L shaped brake lever 2, L shaped brake lever is installed on anti-unexpected L shaped brake lever 2 holds up spring 3 and picking-up power adjusting button 4, switch button 7 on anti-2 times end in contact normally closed switch 6 of unexpected L shaped brake lever, push-button reset spring 10 is housed in normally closed switch 6, brake is connected with brake cylinder 11 on the chassis, brake cylinder push rod 12 is installed in brake cylinder 11, brake cylinder push rod 12 connects auxiliary brake control handle 15, auxiliary brake control handle 15 connects brake axle 16, gas source inlet 9 on normally closed switch 6 connects and resets and enable air outlet II 20 on switch 17, reset and enable and have primary air inlet 18 on switch 17, the air outlet I 19 that resets and enable on switch 17 connects rapid escape valve II 22, the suction port 13 that resets that rapid escape valve II 22 connects on brake cylinder 11, brake suction port 14 on brake cylinder 11 connects rapid escape valve I 21, rapid escape valve I 21 connects the source of the gas outlet 8 on normally closed switch 6.
During normal the use, the driller will prevent when controlling well servicing equipment brake lever 1 that unexpected L shaped brake lever 2 presses, switch button 7 is released, normally closed switch 6 disconnects the gas circuit of leading to brake cylinder 11, this moment, brake cylinder 11 was failure to actuate, the switch button 7 gas conducting that is pressed when accident occurs, and gas enters brake cylinder 11 from the suction port 14 that brakes, brake cylinder push rod 12 stretches out and promotes 15 rotations of auxiliary brake control handle, and auxiliary brake control handle 15 drives brake axles 16 and rotates the tight braking of stopping.
Source of the gas of the present utility model enters initiate mode by the primary air inlet 18 that resets and enable switch 17, and entered by air outlet II 20 in the gas source inlet 9 of normally closed switch 6, the switch button 7 gas conducting that is pressed when accident occurs, gas is completed brake by rapid escape valve I 21 to brake suction port 14 air feed of brake cylinder 11 by source of the gas outlet 8; To reset and enable switch 17 and shift reset position onto when needs reset, this moment, source of the gas entered reset mode by primary air inlet 18, and by air outlet I 19 by reset suction port 13 air feed of rapid escape valve II 22 to brake cylinder 11, brake cylinder push rod 12 is retracted, and the gas at brake cylinder push rod 12 rear portions is discharged to rapid escape valve I 21 through brake suction port 14.
Be understandable that, above about specific descriptions of the present utility model, only for the utility model being described and being not to be subject to the described technological scheme of the utility model embodiment, those of ordinary skill in the art is to be understood that, still can modify or be equal to replacement the utility model, to reach identical technique effect; Use needs as long as satisfy, all within protection domain of the present utility model.
