Hydraulic control circuit mainly is made up of oil pump, unloading overflow valve, brake valve, by pass valve, energy storage, change-over valve, reducing valve etc., and wherein hydraulic valve bank is arranged at the base front portion, and change-over valve group, brake lever assembly are arranged in the operator's compartment, is convenient to driller's operation.
Fig. 1 is the utility model actuating unit, steering unit layout circle, Fig. 2 is the structure cutaway view of the utility model safety tongs, Fig. 3 is the structure semisectional view of the utility model working clamp, and Fig. 4 is a brake lever unit construction scheme drawing, and Fig. 5 is a hydraulic control circuit principle schematic of the present utility model.
In conjunction with the accompanying drawings structure of the present utility model and embodiment are described as follows:
Actuating unit is by brake disc 1; along it axially and be symmetrical in dish; be fixed by bolts to the opposed safety guard-safeguard braking clamp of twin-tub (abbreviation safety tongs) 2 and the normal operation braking clamp (abbreviation working clamp) 3 on the tong holder and be fixed on the tong holder 4 that is welded into by steel plate on the winch base and form; brake disc 1 was connected with winch drum with the brake drum of belt brake with being connected with location dimension of winch drum; location dimension is identical; under the prerequisite that structure space allows; the diameter of brake disc 1 is big as far as possible; general bigger 100 millimeters than the external diameter of brake drum approximately; can reduce the required positive pressure of brake and the pressure of brake shoes like this, thereby reduce wear and generate heat.The structure of tong holder 4 and size can be decided on the winch installing space.
Safety tongs is mainly by oil cylinder cover 20, oil cylinder 23, the piston 21 and the piston rod 27 that are sealed between oil cylinder cover and the oil cylinder, fuse by screw 22, realize the setting nut 24 of compensation of play, be fixed on the caliper 25 on the tong holder 4, friction lining 28 and steel backing 26 are fixed on the brake shoes of one, are connected with piston rod 27, be arranged between oil cylinder and the brake shoes, the disk spring group 29 that is contained on the inner piston rod of caliper chamber constitutes;
Working clamp mainly is fixed on the brake shoes of one by friction lining 28 and steel backing 26,
Be connected mutually with piston 37 and guide rod 33 by screw, realize the guide rod 33 of compensation of play, regulate double-screw bolt 34, pull back spring 35 is fixed on the caliper (being oil cylinder) 32 on the tong holder, oil cylinder cover 36, piston 37 is formed, and piston is sealed in the oil cylinder 32 that has a cylinder cap.
Steering unit by brake lever through part comprise brake lever 41, the axle 42, crank connecting link 43 and brake valve 53, the safety shut-down handle that are fixed on the support be that change-over valve handle 56 is formed, the core of brake lever assembly is a brake valve, in order to the size of control and adjusting brake weight
Hydraulic control circuit is mainly by oil pump 51, unloading overflow valve 52, brake valve 53, by pass valve 54, energy storage 55, compositions such as change-over valve 56, reducing valve 57.Energy storage 55 is main damping, the buffer action of rising in hydraulic circuit; When no oil pressure was out of order in the loop, the hydraulic oil that energy storage stores also can carry out one, twice braking.
Brake valve 43 is to form through improvement on the basis of stacked compression release valve: the one, change rotatablely moving of original regulating handle into handle through axle 42, crank connecting link 43 crank motion with brake lever 41, and the 2nd, with the flow section increasing of original outgate.
Principle of work: the principle of working clamp is, when pulling down brake lever, pressure oil charges into oil cylinder, and piston promotes brake shoes and presses to brake disc and realize braking.Lock torque is directly proportional with the brake lever amplitude of fluctuation.Push back brake lever, oil pressure reduces, and is zero up to being bordering on, thereby pine is stopped.During with the oil-filled brake of working clamp, safety tongs oil-filled pine is simultaneously stopped, safety tongs release oil return when pressing the safety shut-down handle, and the restoring force of disk spring assembly release at this moment promotes piston and imposes positive pressure to brake shoes and realize braking. Hydraulic valve bank 52,54 in the loop is arranged at the base front portion, and change-over valve group 56,57, brake lever assembly 53 amounts of establishing such as grade are convenient to driller's operation in operator's compartment.
Compare with belt brake: the brake torque capacity of disc brake device is big, system Moving usefulness is stable, and thermal diffusivity is good, and manual dexterity is laborsaving, adjusts easy to maintenance, owing to The duty of safety tongs, working clamp is opposite, has just formed the dual brake of safety interlock Mechanism, reliability, security improve greatly.
