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 rope traction monorail crane braking car, comprises frame 1, road wheel 2 and brake shoe 3, and road wheel 2 is installed in frame 1; Also comprise fifth wheel 16, centrifugal binary pair 5, brake triggering device 6, manual pressuring pump 7, spring bearing 11 and cylinder pedestal 15, fifth wheel 16 is installed in frame 1, centrifugal binary pair 5 is arranged in the rotating shaft of fifth wheel 16, brake triggering device 6 is fixed on fifth wheel 16 downsides, and in the time of emergency braking, brake triggering device 6 contacts with centrifugal binary pair 5; Between road wheel 2 and fifth wheel 16, be provided with fuel tank 4, fuel tank 4 has the S. A. 17 of little torsion spring 18 to be connected with frame 1 by cover, brake shoe 3 is arranged on fuel tank 4 upper ends, and fuel tank 4 lower ends are provided with roller 9, and manually pressuring pump 7 is arranged on fuel tank 4 by screw connector; Oil cylinder 13 is installed in frame 1, oil cylinder 13 is positioned at the downside of fuel tank 4, oil cylinder 13 one end are connected with frame 1 by spring bearing 11, the other end is connected with frame 1 by cylinder pedestal 15, the outer oil cylinder urceolus 10 that is provided with of oil cylinder 13, oil cylinder urceolus 10 outer walls are provided with skewback 8, in oil cylinder urceolus 10 inner chambers, spring 12 are installed.
As further improvement of the utility model scheme, described brake triggering device 6 is by steel rope 19, disk 20, screw 21, connection handle 22, and check valve trigger mechanism 23 and connecting panel 24 form.In the time that fifth wheel detects that tractor truck scanning frequency is too fast, the centrifugal binary pair 5 being attached in fifth wheel 2 rotating shafts just can touch brake triggering device 6.Connection handle on brake triggering device 6 can be along the corresponding rotation of screw 21, thereby another piece connecting panel 22 is moved, the sport trigger check valve trigger mechanism 23 of connecting panel 22, thus open check valve to oil cylinder 13 pressure releases.
As further improvement of the utility model scheme, described brake triggering device 6 both can be centrifuged binary pair 5 and touch, and can manually touch by steel rope 19 again.Steel rope 19 can be arranged on leader on man carrier, in the time needing emergency braking because of emergency situation, pulls steel rope 19, can touch equally brake triggering device 6.
As further improvement of the utility model scheme, described spring bearing 11 is welded in frame 1, and described cylinder pedestal 15 is connected with frame 1 by bolt.In dismounting oil cylinder 13 processes, need to first lay down cylinder pedestal 15, because spring 12 has been compressed in oil cylinder urceolus 10, cylinder pedestal 15 is easily ejected by the huge elastic force of spring 12, so have T-shaped screw thread on the base plate of oil cylinder urceolus 13, in handling process, first with T-shaped bolt, oil cylinder urceolus 13 and spring 12 are fixed in frame 1.Spring bearing 11 is fixed in frame 1, is conducive to dismantle oil cylinder 13 and mounting spring 12.
As further improvement of the utility model scheme, described road wheel 2 and fifth wheel 16 are arranged in frame 1 by bolt.
As further improvement of the utility model scheme, described oil cylinder urceolus 10 is welded by solid drawn pipe and baffle plate, forms cavity, and as the track of described spring 12.As shown in Figure 2: oil cylinder urceolus 10 has three solid drawn pipes, together, the left end of innermost layer steel pipe and interlayer steel pipe is by baffle plate weld together, outermost layer steel pipe and interlayer steel pipe right-hand member weld together for mutual sheathing.In cavity between outermost layer steel pipe and interlayer steel pipe, spring 12 is installed, and spring 12 compressions are installed.Such design can alleviator weight, save structure space, can quick and precisely brake again, for brake system provides larger power simultaneously.
As further improvement of the utility model scheme, described little torsion spring 18 1 sides contact with fuel tank 4 walls, and opposite side contacts with frame 1.Can make so little torsion spring in the time of preliminary examination state, when brake shoe 3 contacts with dedicated track, store elastic potential energy, and during to left movement, can discharge elastic potential energy at oil cylinder 13, ensure that brake shoe 3 can de-orbit.
As shown in Figure 4: the as a whole bonding machine of frame 1.Road wheel 2 is standard fitting, is bolted and is installed in frame 1, and the quantity of road wheel 2 has three.Fifth wheel 16 is positioned at the left upper end of frame 1, the both sides that are arranged on dedicated track relative to one of them road wheel 2.As shown in Figure 2: between road wheel 2 and fifth wheel 16, fuel tank 4 is connected in frame 1 by S. A. 17, and there are two earholes fuel tank 4 inner sides, also has two holes with matching in frame 1, through four mutually corresponding holes, fuel tank 4 can be rotated around S. A. 17 S. A. 17.Be provided with brake shoe 3 in fuel tank 4 upper ends, brake shoe 3 surface distribution abrasion resistant particles, increasing friction force, and between brake shoe 3, damping spring is installed, reduce the antagonistic force bringing because of emergency braking.
Before the operation of braking car, first utilize manual pressuring pump 7 to suppress to braking car, hydraulic oil is entered in the oil pocket of oil cylinder 13 by fuel tank 4.In the process of constantly suppressing, because oil cylinder piston is subject to the hydraulic action of hydraulic oil, along oil cylinder 10 inner chambers toward left movement.As shown in Figure 2, when oil cylinder piston is moved to the left, can push up the innermost layer steel pipe of oil cylinder urceolus 10, innermost layer steel pipe is connecting interlayer steel pipe and outermost layer steel pipe by baffle plate, thereby makes oil cylinder urceolus 13 past moving left together with oil cylinder piston.Because spring 12 is fixed on spring bearing 11, and be arranged in interlayer steel pipe and outermost layer steel pipe, in the process of motion, spring 12 is in continuous compression, and storage elasticity potential energy.Fuel tank 4, not only as oil storage equipment, is also equivalent to pipe link.Fuel tank 4 is connected with frame 1 by S. A. 17, on S. A. 17, cover has little torsion spring 18, and little torsion spring 18 along with oil cylinder urceolus 13 and oil cylinder piston are slowly moved to the left, discharges the elastic potential energy of storage, thereby flick fuel tank 4, make brake shoe 3 depart from dedicated track.
In the time running into emergency situation or stop, patcher person can trigger braking trigger mechanism 6 by steel rope 19, connection handle on brake triggering device 6 can be along the corresponding rotation of screw 21, thereby another piece connecting panel 22 is moved, the sport trigger check valve trigger mechanism 23 of connecting panel 22, thus check valve opened to oil cylinder 10 pressure releases.In the process of pressure release, because oil cylinder urceolus 10 and oil cylinder piston 0 do not have hydraulic action, their motions of turning right fast.On oil cylinder urceolus 10, be provided with two little skewbacks 8, the roller 9 that can directly install with fuel tank 4 lower ends contacts, roller 9 meetings side shifting outside braking car, fuel tank 4 can rotate round S. A. 17, and overcome the elastic force of little torsion spring 18, fuel tank 4 upper ends are inwardly rotated, thereby make brake shoe 3 be close to track, force braking car to stop.Meanwhile, little torsion spring 18, under the application force of little skewback 8 pair rollers 9, is transformed into spring potential energy by pressure and stores, so suppressing in process, when cylinder 13 moves right Compress Spring, the elastic potential energy of little torsion spring 18 is converted into kinetic energy, flicks fuel tank 4 brake shoe 3 above.
In the time running into emergency situations, during as operating modes such as disconnected ropes, braking car can be driven over the speed limit.When braking vehicle speed is during while exceeding 2.4m/s or in low angle tunnel, speed can be set to 3.2m/s, and centrifugal binary pair can touch trigger mechanism, thereby completes oil cylinder 10 pressure leak processes, spring 12 resiliences, and braking car completes braking.
