Description

Electronic floating rail gravity type boat davit stopping device

Affiliated technical field

The utility model belongs to railway security parking facility technical field, relates to a kind of be used on railroad siding vehicle is carried out stopping-down and prevents the stopping device of wagon running away.

Background technology

At present, it mainly is hydraulic pressure controlled stopping device and TEL-92 type hydraulic parking device as the stopping device of stopping brake that China is used for the hump marshalling station field, YT type hydraulic parking device and YT-2C, 2D type hydraulic pressure controlled stopping device etc., the greatest problem that this class stopping device exists in actual applications is that its braking potential is the constant force that a value is determined relatively, can not change with the changes in weight of vehicle, can occur light car braking force too big so on the one hand, cause jumping on the wheel even vehicle is slided down and cause the phenomenon of major accident, the purpose that out of reach effectively stops then can appear loaded vehicle on the other hand because the braking force deficiency problem that causes vehicle finely not stop.In addition, when also having car brakeing, existing hydraulic parking device moves forward and backward and high pressure that moment produces makes piston rod and block distortion, wearing and tearing produce the problem of leaking because of piston rod, after wheel enters stopping device, because the leakage of by pass valve, pressurize for a long time, pressure in the brake cylinder can only be in the accumulator pressure (about 1.5～2MPa), so braking effect is relatively poor.

The utility model content

The purpose of this utility model is to overcome the defective that prior art exists, and provides a kind of rational in infrastructure, dependable performance, braking force can be with the self-regulating electronic floating rail gravity type boat davit stopping device of vehicle weight.

Be used to realize that the technical solution of foregoing invention purpose is such: the electronic floating rail gravity type boat davit stopping device that is provided is a kind of inboard brake equipment of two unsteady stock rails (also can be referred to as floating rail) that is arranged on, this device is by the support beam driving and reversing mechanism, support beam, braking rail, the pincers that float are formed, wherein: the support beam driving and reversing mechanism is installed between two stock rails by mount pad, by motor, the change speed gear box that is in transmission connection with motor output shaft and be symmetrically set in the change speed gear box two ends and form with gear box output end bonded assembly advance and retreat device pull bar, advance and retreat device pull bar and stock rail be arranged in parallel, are provided with the support beam erecting bed on the body of rod of advance and retreat device pull bar; Support beam is symmetricly set on the two ends of advance and retreat device pull bar upper support beam erecting bed, and unsteady pincers are the lever member that one two arm of force becomes the obtuse angle to be provided with, and its fulcrum shaft and support beam outer end are hinged, and two force ends are located at the below and the inboard of stock rail respectively; Braking rail is contained in the clamper of floating in the force of stock rail inboard end, and its brake surface is positioned at the stock rail inside front.Braking principle of the present utility model is to utilize the car weight amount that is braked, and by the floatable stock rail and the pincers transmission of floating, makes the braking rail that is installed on the pincers that float produce lateral pressure skating vehicle is braked.In the real work, when the stop position that slips to regulation when vehicle promptly travelled to stopping device section stock rail top, stock rail was rotated around fulcrum shaft by the wheel compressing rear drive pincers that float, and then the friction face that drives braking rail is pressed to wheel, form resisting moment, thereby reach the purpose that makes car brakeing.

Compare with existing other class stopping device, it is big to the utlity model has braking potential, safe and reliable, cost low (cost low 5%～10% compared with similar products), pollution-free, control is convenient, empty wagons is not extruded, advantages such as the ratio of performance to price is good, because total all adopts the lever principle of machinery, be out of order and be easy to search, each parts can both independently be dismantled, so convenient maintenance, greatly reduce maintenance load and service expenditure, the development release of this stopping device provides a kind of safe and reliable for renovating of hump marshalling station field, easy for installation, novel device has wide use promotion prospect cheaply.

The specific embodiment

Referring to accompanying drawing, electronic floating rail gravity type boat davit stopping device described in the utility model is made up of support beam driving and reversing mechanism, support beam 4, braking rail 2, the pincers 3 that float etc.The support beam driving and reversing mechanism is installed between two unsteady stock rails 1 by mount pad 6, its structure as shown in Figure 2, form by motor 10, change speed gear box 9 and advance and retreat device pull bar 8, motor 10 output shafts and change speed gear box 9 are in transmission connection, advance and retreat device pull bar 8 be arranged in parallel with stock rail 1 and symmetry even is loaded on the output shaft at change speed gear box 9 two ends, is provided with the support beam erecting bed and is provided with support beam taper slip pushing block 11 on advance and retreat device pull bar 8.Be the two ends that vertical support beam 4 symmetries to setting are fitted in advance and retreat device pull bar 8 upper support beam erecting beds with stock rail 1, the pincers 3 that float are contained in support beam 4 outer ends.Float pincers 3 structure as shown in Figure 3, its fulcrum shaft and support beam 4 outer ends hinge, two arm of force sections are mutually the obtuse angle setting, two force ends then are arranged on the below and the inboard of stock rail 1 respectively.Braking rail 2 is contained in the force end that is positioned at stock rail 1 inboard of the pincers 3 that float, and its brake surface is positioned at the stock rail inside front.The process that this stopping device is braked skating vehicle is: when stopping device is received brake command, motor 10 right-hand revolutions, advance and retreat device pull bar 8 extends to both sides, makes taper slip pushing block 11 promote support beam 4 to two lateral movements and locking, the outage under travel switch control of motor 10 this moment; When vehicle ' during to stopping device section stock rail 1 top, stock rail 1 is rotated around fulcrum shaft by float pincers 3 of wheel compressing rear drive, and then the friction face that drives braking rail 2 forms resisting moment to wheel, thereby makes the vehicle jogging and stop; When stopping device is received the alleviation order, the rotation of motor 10 anticlockwise directions, advance and retreat device pull bar 8 inwardly shrinks and taper slip pushing block 11 is moved inward, under the promotion of restorer 7 by support beam 4 will float pincers 3 and braking rail 2 inwardly retract, motor 10 outage under travel switch control afterwards is in relieved state simultaneously.In actual the use, it is one that stopping device can be formed 2,3,4,5 joints as required, can adopt two or three to be installed in series, every interstation is apart from deciding according to a station particular case, its row is installed in the stopping device middle part to mechanism, and control box is installed in the stopping device outside, is convenient to debugging and maintenance.Label 5 is a strutbeam among Fig. 1.
