The present embodiment provides the vehicle parking anti-slip device that is applicable to hair line shown in a kind of Fig. 1, except oil cylinder, left and right parts are all with basic circuit Central Symmetry, parts mainly comprise joist 8, be arranged on two parallel stock rails 2 at joist 8 both ends, be arranged on wild card rail 1 and the Nei Ka rail 4 of stock rail 2 inside and outside both sides, be arranged on the oil cylinder 11 of joist 8 tops, be arranged on the supporting seat 7 at oil cylinder 11 both ends, the braking rail 6 that is arranged on supporting seat 7 tops, outer end, this vehicle parking anti-slip device mainly comprises parking anti-running device frame and movement transmission structure; Stock rail 2 is connected between interior card rail 4 and wild card rail 1, and is connected with joist 8 by interior card rail 4, forms parking anti-running device frame; Movement transmission structure comprises oil cylinder 11, supporting seat 7 and braking rail 6.
Interior card rail 4 is provided with inner bayonet 16, and wild card rail 1 is provided with outer bayonet 15, interior card rail 4 with on wild card rail 1, be provided be connected in the bolt 3 of card rail 4 and wild card rail 1; Matched with inner bayonet 16 and outer bayonet 15 in the lower end of stock rail 2, and by bolt 3, stock rail 2 is stuck between interior card rail 4 and wild card rail 1.Interior card rail 4 connects with the below at the both ends of joist 8.The outer end of supporting seat 7 is provided with bearing pin 5, the top at joist 8 both ends is provided with the position-limited trough 18 matching with bearing pin 5, by making bearing pin 5 and coordinating of position-limited trough 18 supporting seat 7 and joist 8 be connected, the alleviation of parking anti-running device and braking motion complete in the interior rolling of position-limited trough 18 by bearing pin 5.
Between joist 8 and oil cylinder 11, the bottom of oil cylinder 11 is provided with two anchor plates 9, and the two ends of anchor plate 9 are provided with the limited step 19 of outstanding its upper surface.Be positioned at oil cylinder 11 side of cylinder block and be provided with travel switch 10, for automatic control.The right side that is positioned at oil cylinder 11 below joists 8 is provided with alleviates oil pipe 12 and brake pipe 14, connect and fix by oil pipe gib 13 and alleviate oil pipe 12 and brake pipe 14 on joist 8, alleviate oil pipe 12 and brake pipe 14 and carry, reflux for the hydraulic oil for whole parking anti-running device.Between two anchor plates 9, have certain interval, alleviation oil pipe 12 is positioned at the left side of brake pipe 14.
Wherein, joist 8 is generally 5 or 6.
Principle of work of the present utility model: the oil cylinder 11 of this parking anti-running device is subject to the constraint of the limited step 19 on anchor plate 9, the deflection of constrained motion transferring structure in the time of operation; After movement transmission structure all connects, oil cylinder 11 by and two anchor plates 9 between gap adjustment assembly error; Two anchor plates 9 play supporting role to oil cylinder 11; In the time that parking anti-running device moves, bearing pin 5 in movement transmission structure does friction of rolling in position-limited trough 18, the setting of position-limited trough 18, anchor plate 9, when making this parking anti-running device in braking and alleviating, friction drag is less, and flexible movements are reliable, and response time is shorter, mechanism's centering is reliable, vehicle by time there will not be and rub wheel phenomenon.
This parking anti-running device is without basis is installed, quick and easy for installation, only need block station track is installed when installation, noiseless to adjacent line operation, and it is simple, convenient to safeguard; This parking anti-running device is arranged on the automatic control for realizing braking or alleviating of signal that the travel switch 10 on oil cylinder 11 produces; Alleviation oil pipe 12 on this parking anti-running device accesses the alleviation chamber of oil cylinder 11, and brake pipe 14 accesses the brake chamber of oil cylinder 11.
This parking anti-running device is applicable to the anti-slip of large, medium and small bowl end vehicle, should be arranged in line linear section, is applicable to standard gauge 1433～1441mm, and stock rail rail type is hump field or other occasion of 43kg/m or 50kg/m.General 4 regulating devices of pressing, can increase and decrease joint number as required, and as can be seen here, the joist 8 of this utility model parking anti-running device is generally 5 (4 joints) or 6 (5 joint), and the movement transmission structure being correspondingly arranged on each joist is also 5 or 6.
Working process of the present utility model and mode:
The utility model parking anti-running device has retarder location and alleviates two working positions in position, and the implementation procedure of each working position is described below respectively:
The working process of retarder location and mode:
In the time that brake pipe 14 passes into hydraulic oil, hydraulic oil enters the brake chamber of oil cylinder 11 by brake pipe 14, the hydraulic oil that oil cylinder 11 is alleviated in chamber flows in alleviation oil pipe 12, the piston rod that hydraulic oil promotes oil cylinder 11 moves, and the movement transmission structure of oil cylinder 11 ends is rolled in position-limited trough 18 by bearing pin 5.In this process, the movement transmission structure of the less side of friction drag is first outwards mobile, when oil cylinder 11 is encountered after the limited step 19 on anchor plate 9, this movement transmission structure stops mobile, another movement transmission structure starts outside movement, and in the time that between the friction face of braking rail 6, distance reaches 1365mm, parking anti-running device is just in retarder location, now travel switch 10 sends speed-slackening signal, can implement anti-slip effect to the vehicle entering.
Alleviate working process and the mode of position:
In the time that alleviation oil pipe 12 passes into hydraulic oil, hydraulic oil enters the alleviation chamber of oil cylinder 11 by alleviating oil pipe 12, hydraulic oil in oil cylinder 11 brake chambers flows in brake pipe 14, hydraulic oil promotes the piston rod of oil cylinder 11 and inwardly retracts, and the movement transmission structure at oil cylinder 11 two ends is rolled in position-limited trough 18 by bearing pin 5.In this process, the movement transmission structure of the less side of friction drag first moves inward, when bearing pin 5 is encountered after position-limited trough 18, this movement transmission structure stops mobile, and another movement transmission structure starts to move inward, in the time that between the friction face of braking rail 6, distance reaches 1316mm, parking anti-running device is just in alleviating position, now travel switch 10 sends mitigation signal, and parking anti-running device is ineffective to vehicle, and vehicle can pass through from parking anti-running device.
More than exemplifying is only to casehistory of the present utility model, does not form the restriction to protection domain of the present utility model, within the every and same or analogous design of the utility model all belongs to protection scope of the present invention.
