Abstract
The utility model relates to a self-propelled brake control device of a drilling and repairing machine, which is characterized by comprising a pair of working pliers GQ, a pair of safety pliers AQ and an auxiliary brake FS. An emergency brake valve JF is respectively connected with the working pliers GQ, the safety pliers AQ and the auxiliary brake FS through an air-controlled liquid change valve QKY, a hydraulic controlled change valve YKF, a normally closed relay JJQ and a shuttle valve SF to form an interlocking air-hydraulic control return circuit. The working pliers GQ and the safety pliers AQ are both hydraulic disc type brake pliers. The auxiliary brake FS is a water-cooling air controlled push disc brake. Compared with the prior art, the self-propelled brake control device of the drilling and repairing machine has the advantages that 1 the emergency brake valve can simultaneously control the working pliers and the safety pliers and the auxiliary brake to perform braking, thereby eliminating potential safety hazards of braking; and 2 operating strength of driller workers is reduced by using the hydraulic disc type brake pliers.
Description
Technical field
The utility model relates to the drilling and repairing machine field, particularly a kind of self-propelled drilling and repairing machine braking control device.
Background technology
Drilling and repairing machine needs the running of driller's operating personal control driving engine, gear, winch running and the brake of change speed gear box, the control of assist brake, the control of rotating disk, the control of hydraulic oil pump, the control of air slips, the control of pump group, control of spinner or the like when operation.The band brake of connecting rod mechanism is adopted in the brake control of present most of drilling and repairing machine winches, and it is very painstaking under the high speed heavy load, to brake, and it is tired to make drilling and repairing well process driller personnel be very easy to.
Summary of the invention
The purpose of the utility model provides a kind of self-propelled drilling and repairing machine braking control device, overcomes the deficiency of prior art, alleviates driller operating personnel's labour intensity, raises labour efficiency.
For solving the problems of the technologies described above, the technical scheme of the utility model is:
Self-propelled drilling and repairing machine braking control device; Comprise working clamp GQ, safety tongs AQ, assist brake FS, emergency stop valve JF is connected to form chain gas-liquid control loop with working clamp GQ, safety tongs AQ, assist brake FS respectively through gas control liquid change-over valve QKY, pilot operated directional control valve YKF, normally closed air feeding apparatus JJQ, shuttle valve SF.
Said working clamp GQ and safety tongs AQ are all the hydraulic disc brake pincers.
Said assist brake FS is the brake of water-cooled gas control push-plate.
Compared with prior art, the beneficial effect of the utility model is: 1) emergency stop valve can the while Control work clamp, safety tongs, and assist brake carries out drag, has eliminated the brake potential safety hazard.2) use hydraulic disc brake to reduce driller personnel's operation intensity.
Description of drawings
Fig. 1 is the utility model embodiment gas-liquid control loop scheme drawing.
Among the figure: dotted line is a gas circuit for the oil circuit solid line
The specific embodiment
Be described further below in conjunction with the specific embodiment of accompanying drawing the utility model:
Seeing Fig. 1, is the self-propelled drilling and repairing machine braking control device of the utility model embodiment gas-liquid control loop scheme drawing, in the loop; Emergency stop valve JF is connected to form chain gas-liquid control loop with working clamp GQ, safety tongs AQ, assist brake FS respectively through gas control liquid change-over valve QKY, pilot operated directional control valve YKF, normally closed air feeding apparatus JJQ, shuttle valve SF, and after pressing emergency stop valve JF, source of the gas gets into normally closed air feeding apparatus JJQ; And normally closed air feeding apparatus JJQ is opened, and make power gas source pass through shuttle valve SF and get into assist brake FS, realize the assist brake braking; Cut off the source of the gas that gets into gas control liquid change-over valve QKY simultaneously; And then cut off the hydraulic circuit that gets into safety tongs AQ and pilot operated directional control valve YKF, and make safety tongs GQ short oil brake, working clamp GQ pilot operated directional control valve YKF gets through the entering working connection under the effect that control oil loses; Make working clamp GQ oil-feed brake; Thereby realize assist brake FS, working clamp GQ, safety tongs AQ brakes simultaneously.Working clamp GQ and safety tongs AQ are all the hydraulic disc brake pincers.Assist brake FS is the brake of water-cooled gas control push-plate.
Working clamp control cock GQF be used for Control work pincers GQ braking with unclamp.Safety tongs control cock AQF is used for controlling the braking of safety tongs AQ and unclamping.Assist brake valve FSF is used for controlling the braking of assist brake FS and unclamping.Emergency stop valve JF is used for braking winch when danger occurring.
