Abstract
The utility model discloses an intelligent hydraulic braking system for a full-hydraulic crawler-type cutting drilling machine. The intelligent hydraulic braking system comprises a brake and a solenoid valve, wherein the brake comprises a brake oil cylinder, a brake shaft and a brake pad; the brake oil cylinder is communicated with a pilot pressure oil source through the solenoid valve, a piston of the brake oil cylinder is connected with the brake pad, one end, positioned in a cylinder barrel, of the piston is connected with a spring, the brake pad is mounted at one end of the brake shaft, the brake shaft is connected with the chain, the chain wheel and a motor, when the brake oil cylinder is communicated with the pilot pressure oil source, the piston retracts to compress the spring and drive the brake pad to open at the same time, the brake shaft, the chain, the chain wheel and the motor return to the normal state, when the brake oil cylinder is disconnected from the pilot pressure oil source, the spring pushes the piston out and drive the brake pad to close at the same time, the brake is locked, so that the chain, the chain wheel and the motor are braked. The intelligent hydraulic braking system for the full-hydraulic crawler-type cutting drilling machine is simple to operate, flexible and convenient, safe and reliable, time can be greatly saved, and the operation efficiency can be improved.
Description
Technical field
The utility model relates to a kind of drill rig components, particularly a kind of intelligent hydraulic braking system of all hydraulic caterpillar cutting drill.
Background technique
When rig work, drilling rod need to rotate and feeding, in the time of transition, need to stop the operation of drilling rod, there is security incident or damage machine in order to avoid drilling rod falls, but the rig using at present does not generally all have drilling rod break, need to brake time, can only take straightforward procedure that drill rod is inserted to chain braking, not only inconvenience but also unreliable, hides some dangers for to safety.
Model utility content
The technical problems to be solved in the utility model is: a kind of simple to operation, braking brill mechanical electronic hydraulic intelligent brake device reliably of design, and to overcome the existing deficiency of above-mentioned prior art.
The technological scheme that the utility model is taked is: a kind of intelligent hydraulic braking system of all hydraulic caterpillar cutting drill, comprise break and solenoid valve, described break comprises brake cylinder, brake shaft and braking plate, described brake cylinder is communicated with pilot pressure oil sources by solenoid valve, the piston of brake cylinder is connected with described braking plate, and flexible drive braking plate by piston open or closed, described braking plate is arranged on one end of brake shaft, described brake shaft and chain sprocket and motor are coaxially fixedly connected, thereby by locked brake shaft, chain sprocket and motor are braked when braking plate is closed, brake shaft when braking plate opens, chain sprocket and motor return to normal.
Its further technological scheme is: one end that the piston of described brake cylinder stretches out cylinder barrel connects braking plate, be positioned at one end linking springs of cylinder barrel, when brake cylinder and pilot pressure oil sources are connected, piston retraction by spring-compressed, drive braking plate to open simultaneously, when brake cylinder and pilot pressure oil sources disconnect, spring ejects piston, drives braking plate closure simultaneously.
Owing to adopting technique scheme, the intelligent hydraulic braking system of a kind of all hydraulic caterpillar cutting drill of the utility model has following beneficial effect:
1. because the intelligent hydraulic braking system of this kind of all hydraulic caterpillar cutting drill can be passed through the working state of electromagnetic valve brake cylinder, thereby control opening or closure of braking plate, reach the object of brake shaft and chain sprocket and motor braking, simple to operate, flexible, safe and reliable, can avoid the loss causing because of accident;
2. in the time that rig needs conversion work state or transition or stops, use the utility model a kind of all hydraulic caterpillar cutting drill intelligent hydraulic braking system energy fast braking drilling rod or return to normal, can save time, improve operating efficiency.
The technical characteristics of the intelligent hydraulic braking system of a kind of all hydraulic caterpillar cutting drill below in conjunction with drawings and Examples to the utility model is further described.
Accompanying drawing explanation
Fig. 1: the intelligent hydraulic brake system structure schematic diagram of a kind of all hydraulic caterpillar cutting drill of the utility model.
In figure:
1-break, 11-brake cylinder, 12-brake shaft, 13-braking plate, 2-chain sprocket, 3-motor, 4-solenoid valve, P-pilot pressure oil sources, T-fuel tank, A, B-motor hydraulic fluid port.
Embodiment
A kind of intelligent hydraulic braking system of all hydraulic caterpillar cutting drill, comprise break and solenoid valve, described break comprises brake cylinder 11, brake shaft 12 and braking plate 13, described brake cylinder 11 is communicated with pilot pressure oil sources P by solenoid valve 4, the piston of brake cylinder is connected with described braking plate, and flexible drive braking plate by piston open or closed, described braking plate is arranged on one end of brake shaft, described brake shaft and chain sprocket and motor are coaxially fixedly connected, thereby by locked brake shaft, chain sprocket and motor are braked when braking plate is closed, brake shaft when braking plate opens, chain sprocket and motor return to normal.
One end that the piston of described brake cylinder stretches out cylinder barrel connects braking plate, be positioned at one end linking springs of cylinder barrel, when brake cylinder and pilot pressure oil sources are connected, piston retraction by spring-compressed, drive braking plate to open simultaneously, when brake cylinder and pilot pressure oil sources disconnect, spring ejects piston, drives braking plate closure simultaneously.
working principle
By controlling the brake cylinder 11 of break, thereby can make braking plate 13 closure brake axle 12(not rotate); Because brake shaft 12 and chain sprocket 2 and motor 3 are coaxially fixedly connected, in the time that brake shaft 12 is braked, chain sprocket 2 and motor 3 are also subject to braking (can not rotate).
When operation transition: solenoid valve 4 obtains the disconnected pilot pressure oil sources P of TURP, and brake cylinder 11 returns to normal, and holds out against braking plate and makes braking plate closure, thereby brake shaft 12 is braked, and then motor 3 and chain sprocket 2 are braked by the spring force of self;
When operation: solenoid valve 4 dead electricity, pilot pressure oil sources P makes brake cylinder 11 spring force compressions, and piston driving braking plate 13 separates to be opened, and brake shaft 12, chain sprocket 2 and motor 3 return to normal and can freely move;
In the time stopping: pilot pressure oil sources P is zero, brake cylinder 11 holds out against braking plate 13 by the spring force of self brakes brake shaft 12, and then motor 3 and chain sprocket 2 are braked.
