Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As depicted in figs. 1 and 2: a kind of wire saws clamping-rail braking car, comprises frame 1, frame 1 is provided with running gear, brake equipment and speed measuring device.Described running gear comprises and is arranged on frame 1 both sides and the road wheel 8 moved on track 18, the track adjusting wheel 9 along track 18 flank movement is installed in frame 1 both sides, road wheel 8 and track adjusting wheel 9 on track 18 and side cooperatively interact, make frame 1 can moving along track 18 stability and safety; Described brake equipment comprises the retarding spring assembly 2 be arranged in frame 1, retarding spring assembly 2 has four, retarding spring assembly 2 is connected with brake cylinder 3, brake cylinder 3 has two, every two retarding spring assemblies 2 and a brake cylinder 3 are one group, the two ends of retarding spring assembly 2 and brake cylinder 3 two ends interconnect by being connected bearing pin, by the motion of the motion thus control retarding spring assembly 2 that control brake cylinder 3.Brake cylinder 3 connects the brake shoe brake cheek 6 be attached at above track 18 by connecting rod mechanism 5, the braking cooperatively interacted with brake shoe brake cheek 6 is installed in frame 1 both sides and supports 7, for increasing brake shoe brake cheek 6 and braking support 7 and friction force during rail contact, brake shoe brake cheek 6 and braking support 7 surface all have hard metal particles to form.
Described speed measuring device comprises and is arranged on frame 1 side and the fifth wheel 10 moved on track 18, fifth wheel 10 is connected with the flexible axle 11 that can transmit rotating speed and moment of torsion, flexible axle 11 is mounted on the centrifugal binary pair 12 in frame 1, centrifugal binary pair 12 connects centrifugal flip flop equipment 13, centrifugal flip flop equipment 13 controls the turnover of hydraulic oil in fuel tank 4 by the blowdown valve 21 be arranged in frame 1, thus make brake cylinder 3 reciprocating, reach the object that braking garage walks and brakes.Frame 1 is provided with draw ring 16, and draw ring 16 connects centrifugal binary pair 12, thus can manual operation, according to braking car motion conditions, makes braking garage walk or brake.
As shown in Figure 3: pressuring pump 14 provides required pressure for whole hydraulic efficiency pressure system, and by accumulator 15 storage compartment pressure, so that when the system pressure drops, accumulator 15 can hold-off pressure, maintains whole system running.When braking car motion hypervelocity, will trigger and anxious stop control cock 23, system decompression, thus making brake cylinder 3 resilience, braking car is cooperatively interacted by brake shoe brake cheek 6 and braking support 7, and locking, on track 18, makes braking car stop; When manual triggers draw ring 16, manually actuated control valve 22 can be made to reset, thus make system decompression, brake cylinder 3 resilience, system locking, braking car stops.
As described in Fig. 4 and Fig. 5: in braking procedure, retarding spring assembly 2 and brake cylinder 3 cooperatively interact, before braking garage car, by pressuring pump 21 in brake cylinder 3 left side oil pocket in injection liquid force feed, oil cylinder stroke is shunk, because retarding spring assembly 2 two ends are connected with brake cylinder 3 two ends, retarding spring 28 will be compressed, by connecting rod mechanism 5 and brake shoe brake cheek 6 with brake support 7 and be connected, brake shoe brake cheek 6 and braking support 7 are separated with track 18, brakes garage and walk; During braking, brake cylinder 3 draining, pin shaft III 27 is fixed, connecting rod in connecting rod mechanism 5 rotates around pin shaft III 27, when the retarding spring 28 in retarding spring assembly 2 extends, under the thrust of brake cylinder 3, pin shaft II 26 level is to left movement, namely rotate around pin shaft III 27, cause bearing pin I 25 and brake shoe brake cheek 6 to move downward, braking support 7 upward movement, thus make brake shoe brake cheek 6 and braking support 7 be adjacent to track 18, grip track 18, completes braking.
Two kinds of main brake mode: the first is braked by centrifugal binary pair, when braking vehicle speed more than 2.6m/s, rotating speed and moment of torsion are delivered to centrifugal binary pair 12 by flexible axle 11 by fifth wheel 10, centrifugal binary pair 12 triggers brake triggering device 13, cause brake cylinder 3 pressure release, retarding spring 28 resilience, brake shoe brake cheek 6 and braking support 7 cooperatively interact also locking in orbit; The second is braked, and manually triggers, when patcher person finds that emergency situation needs to stop, pull draw ring 16, trigger brake triggering device 13, cause brake cylinder 3 pressure release, retarding spring 28 resilience, brake shoe brake cheek 6 and braking support 7 cooperatively interact also locking in orbit.
