Abstract
The utility model discloses a speed regulating device for a downhole drill for a surface mine. The speed regulating device comprises a main oil way, throttle valves and a directional valve. The directional valve is arranged on the main oil way. The two ends of the directional valve are connected with the throttle valves. The directional valve can be an electromagnetic directional valve or a hydraulic directional valve. When the electromagnetic directional valve is used, the control end of the electromagnetic directional valve is controlled by the electromagnet control signal of an operation adjustment change-over directional valve. When the hydraulic directional valve is used, control oil comes from the operation adjustment change-over directional valve and is logically controlled by the operation adjustment change-over directional valve. The utility model has the advantages that the structure is simple, the operation is convenient, the performance is reliable, the cost performance is high, and the energy-saving effect of the complete machine is better when the speed regulating device is combined with the pump with the LS feedback.
Description
Technical field
The utility model relates to a kind of down-the-hole drill, particularly relates to a kind of opencut with the down-the-hole drill arrangements for speed regulation.
Background technology
But opencut down-the-hole drill operating mechanism separated into two parts, a part is used for the walking of this machine, and the position before the operation is adjusted, and this part required flow is big, pump delivery output at this moment.Another part is used for the bore operation of down-the-hole drill, and this part should be able to be adjusted the speed of drilling rod revolution and unit head propelling according to rock behavio(u)r, promptly controls corresponding flow.The Flow-rate adjustment control device that does not have drilling rod revolution and unit head to advance in the existing down-the-hole drill, this makes that rig flow when bore operation is bigger, causes the waste of the energy so on the one hand; Can not adjust the fltting speed of rig on the other hand as required, easily cause the generation of rig drilling tool damage accident.
The utility model content
The purpose of this utility model provides a kind of opencut with the down-the-hole drill arrangements for speed regulation, and this arrangements for speed regulation can be regulated drilling rod revolution and unit head fltting speed as required.
For realizing above-mentioned purpose, the technical solution adopted in the utility model is: the working connection of down-the-hole drill is provided with direction valve, and the two ends of described direction valve also are connected to choke valve.
With in the arrangements for speed regulation, described direction valve is an electromagnetic direction valve to above-mentioned opencut with down-the-hole drill, and control end is subjected to operation to adjust the magnet control signal controlling of conversion direction valve.
With in the arrangements for speed regulation, described direction valve is the hydraulic control direction valve to above-mentioned opencut with down-the-hole drill, and control oil derives from operation and adjusts the conversion direction valve, and is subjected to the logic control of this valve.
Advantage of the present utility model: 1. the utility model arrangements for speed regulation of adopting adjustable throttling and reversal valve to compose in parallel have simple in structure, dependable performance, the use element is few, fault rate is low advantage; 2. capacity usage ratio height during the utility model operation, spill losses is few; 3. it is low to adopt the utility model and the banked direction control valves that does not have the LS feedback to be used in combination the hydraulic pressure cost, the cost performance height; 4. the easy to operate practicality of the utility model according to different petrophysical properties, is only regulated throttle grip and is changed drilling rod propelling and speed of gyration.
Description of drawings
Be further described below in conjunction with the structure and the operating principle of the drawings and specific embodiments utility model:
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Referring to Fig. 1, the utility model comprises working connection 1, choke valve 2, direction valve 3, and direction valve 3 is located on the working connection 1, and the two ends of direction valve 3 also are connected to choke valve 2.
In the present embodiment, described direction valve 3 can be electromagnetic direction valve or hydraulic control direction valve, and when adopting electromagnetic direction valve, the control end of electromagnetic direction valve is subjected to operation to adjust the magnet control signal controlling of conversion direction valve 4.When adopting the hydraulic control direction valve, control oil derives from operation and adjusts conversion direction valve 4, and is subjected to the logic control of this valve.
Operating principle of the present utility model is: when the position before down-the-hole drill walking, the operation was adjusted, required flow was big, and at this moment direction valve 3 is opened, the output of pump delivery.When the down-the-hole drill bore operation, should be able to adjust the speed of drilling rod revolution and unit head propelling according to rock behavio(u)r, promptly control corresponding flow.At this moment adjust the signal at stop direction valve of conversion direction valve 4 according to operation, and open choke valve 2, by the required flow of choke valve 2 controls, can adjust the speed of drilling rod revolution and unit head propelling like this according to rock behavio(u)r, help the down-the-hole drill steady operation, reduce fault rate, and energy conservation.
