Summary of the invention
The objective of the invention is to overcome deficiency of the prior art, a kind of cableway power-off braker simple in structure, reliable, easy to use is provided.
Cableway power-off braker of the present invention, it comprises the brake wheel that is located on the cableway traction drive shaft, the outer ring of brake wheel is provided with brake band, brake band one end is fixed on the ground of equipment by pin, the other end is fixed on the block plate by pin, and block plate links to each other with the piston rod end of hydraulic actuating cylinder, and piston rod is provided with retarding spring, hydraulic actuating cylinder is provided with the hydraulic control system of its motion of control, and hydraulic control system is provided with the electrical controller that links to each other with the cableway driving motor.
Described hydraulic control system comprises control cock in parallel with hydraulic actuating cylinder respectively, Hydraulic Pump and safety valve, and the exit of Hydraulic Pump is provided with the check valve that prevents the hydraulic oil adverse current, also is provided with pressure relay on the hydraulic actuating cylinder; Described electrical controller comprises the AC contactor that links to each other with the cableway driving motor, also comprises normally open push button switch SB2, the normally closed push button switch SB1 and the open contact S that link to each other with AC contactor, and open contact S links to each other with pressure relay.
Since adopt technique scheme, the such beneficial effect of cableway power-off braker tool of the present invention, and the cableway braking in the time of can realizing sudden power is avoided because of the manually untimely contingency that may cause of control brake; Also can realize braking brake normally in service, and in brake, cut off the power supply of cableway driving motor that prevent to damage electrical motor, it is simple in structure, reliable, and is easy to use, has practicality widely.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Fig. 2 is a circuit connection diagram of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing one embodiment of the present of invention are further described:
Cableway power-off braker of the present invention, shown in Figure 1, it is by brake wheel 1, brake band 2, retarding spring 3, block plate 10, pin 11 and 12, single-action hydraulic cylinder 4 and hydraulic control system are formed, brake wheel 1 is connected with cableway drive wheel coaxial rigid, brake band 2 is enclosed on the outer ring of brake wheel, one end of brake band 2 is fixed on the ground of equipment with pin 12, other end movable end links together with pin 11 and the block plate 10 that is fixed on the hydraulic cylinder piston boom end, the movable end of brake band 2 can be moved to the left under the effect of retarding spring 3 and brake band 2 is packed tightly on brake wheel 1, also can move right under the hydraulic actuating cylinder effect and brake band and brake wheel are disengaged.Retarding spring 3 is enclosed within the external part of unidirectional hydraulic cylinder piston rod, and an end is spacing by the left side of the cylinder body of hydraulic actuating cylinder, and an end is spacing by block plate.When brake band was pressed on the brake wheel, the cableway braking was out of service; After brake band and brake wheel disengaged, then cableway can normally move.Hydraulic control system is by check valve 5, pressure relay 6, safety valve 7, Hydraulic Pump 8, control cock 9 is formed, safety valve 7, Hydraulic Pump 8 and control cock 9 are in parallel with hydraulic actuating cylinder 4, and the check valve 5 that prevents the hydraulic oil adverse current is equipped with in the exit of Hydraulic Pump 8, and the pressure relay 6 of control AC contactor KM break-make is housed on the hydraulic control system.Shown in Figure 2, KM is an AC contactor, and S is the open contact in the pressure relay, and SB1 is a normally closed push button switch, and SB2 is a normally open push button switch, and M is the cableway driving motor, and L1, L2, L3 are the three-phase alternating current electrical input.When the open contact S in the pressure relay 6 makes the release of hydraulic efficiency pressure system high-pressure side, cut off the control power supply of AC contactor KM, thereby disconnect the power supply of cableway driving motor M.
Principle of work: it is overhanging that retarding spring 3 can drive piston rod, and piston rod also can make spring continue compression.Retarding spring 3 precompressed compression certain-lengths during installation, the spring force of generation can be pressed on brake band 2 on the brake wheel 1, and the cableway system braking guaranteed safety when the energy that utilizes the compression brake spring to store was realized sudden power, also can brake normally in service; With the propulsive effort compression spring of hydraulic actuating cylinder 4, after the hydraulic actuating cylinder release, the spring elongation is pressed on the brake wheel brake band, realizes braking.
When starting cableway, to the electromagnet energising of control cock 9, its control cock spool moves to left earlier, path between hydraulic efficiency pressure system high-pressure side and the fuel tank cuts off, primer fluid press pump 8, process check valve 5 is to the hydraulic actuating cylinder fuel feeding, when the hydraulic coupling on acting on hydraulic cylinder piston surpasses spring force, the piston rod compression spring also moves right, brake band 2 disengages with brake wheel 1, and the open contact S closure in the pressure relay 6 is pressed the SB1 button simultaneously, start cableway and drive alternating-current motor/AC motor M, cableway brings into operation.
When the cableway system sudden power, the electromagnet dead electricity in the control cock 9, spool moves right, the hydraulic efficiency pressure system high-pressure side communicates with fuel tank, and the hydraulic actuating cylinder release drives lower piston rod at compressed spring and moves to left, brake band 2 is pressed on the brake wheel, cableway system braking, out of service.
In normal course of operation, disconnect the power supply of control cock 9, then cableway system braking, because the hydraulic efficiency pressure system high-pressure side communicates with fuel tank, and the open contact S of pressure relay disconnects, electrical motor M is out of service simultaneously.In brake wheel 1 braking, cableway driving motor M can not start, and cuts off motor power when braking, and prevents that electrical motor from damaging.
