Specific embodiment
For the content of the invention, feature and effect of the present invention can be further appreciated that, following examples are hereby enumerated, and coordinate accompanying drawing Describe in detail as follows:
Refer to Fig. 1-Fig. 6, a kind of rail bridge with auto-reset function, including the first fixed plate 1, sensor stand 2nd, first sensor 3, second sensor 4, thrust pin 5, supporting pin 6, passive push rod fairlead 7, spring 8, crank 9, second are consolidated Fixed board 10, electric pushrod 11, pusher bar support 12, active push rod 13, active push rod fairlead 14, passive push rod 15.
The thrust pin 5 is inserted in first fixed plate 1 by jack.The passive push rod fairlead 7 is fixed on In first fixed plate 1, the passive push rod fairlead 7 has guiding cross-drilled hole 7-1.The passive push rod 15 is inserted into described On the guiding cross-drilled hole 7-1 of passive push rod fairlead 7.The spring 8 is sleeved on the passive push rod 15 and located at the guiding In cross-drilled hole 7-1.The supporting pin 6 is between the thrust pin 5 and passive push rod fairlead 7.The middle part of the crank 9 passes through Hinge is on the top of the supporting pin 6.The two ends of the crank 9 have chute, and the two ends of the crank 9 are respectively by sliding Thrust pin 5 described in groove and hinge and passive push rod 15.The sensor stand 2 is arranged in first fixed plate 1, institute State sensor stand 2 and be arranged on the sensing located at the side of the thrust pin 5, the first sensor 3 and second sensor 4 On device support 2.
In the present embodiment, sensor stand 2 is bolted the side for being installed on the first fixed plate 1;Supporting pin 6 passes through Interference fit is installed on the middle part of the first fixed plate 1.Passive push rod fairlead 7 is bolted on the another of the first fixed plate 1 Side.
The first sensor 3 and the parallel installation of second sensor 4, distance therebetween is moved up for thrust pin 5 Maximum displacement.
Thrust pin 5 includes sensor target 5-1 and bearing pin body 5-2;Bearing pin body 5-2 is mainly used in the safety backstop of dolly; Sensor target 5-1 is demountable structure, is easy to safeguard.
Passive push rod 15 includes body of rod 15-1, baffle ring 15-2 and sensor target 15-3 in the present embodiment;Body of rod 15-1 is used In spring 8 is installed, baffle ring 15-2 then provides backstop for spring;Sensor target 15-3 is similarly demountable structure and is easy to safeguard.
Passive push rod fairlead 7 includes rectangular channel 7-2, is oriented to cross-drilled hole 7-1, bullport 7-3 and mounting seat 7-4;Passively push away Bar fairlead 7 is fixed in the first fixed plate 1 by mounting seat 7-4, because bullport 7-3 is deposited in passive push rod fairlead 7 The aligning requirements between two tracks can reduced.
The pusher bar support 12 is fixed in second fixed plate 10, and the active push rod fairlead 14 is fixed on described In second fixed plate 10, the active push rod fairlead 14 has pilot hole, and the front end of the active push rod 13 is inserted into described In the pilot hole of active push rod fairlead 14, the rear end of the active push rod 13 is connected with the electric pushrod 11.It is described passive Push rod fairlead 14 and active push rod fairlead 7 it is relative and between be provided with gap.
The operation principle of rail bridge is as follows:
(1) when small rail car did not needed rail
In this case, the thrust pin 5 of rail bridge is in locking state, and the bearing pin body 5-2 of thrust pin 5 is inserted in the first rail In road 16.Due to the obstruction of thrust bearing pin 5, small rail car to be rested on and cannot run to second by the first track 16 at the A of position On track 17.In addition the locking state of thrust pin 5 can also effectively prevent the car slipping phenomenon of small rail car, and then small rail car is firm It is limited in firmly on the first guide rail 1.
(2) when small rail car needed rail
In this case, first control system is received after the signal that small rail car needed rail, sends instruction control The action of electric pushrod 111, electric pushrod 11 drives active push rod 13 to travel forward;When active push rod 13 passes through the He of the first track 16 When in the guiding cross-drilled hole 7-1 that the gap of the second track 17 is entered in passive push rod fairlead 7, active push rod 13 continues to promote forward The passive forward motion of push rod 15, compression spring 8;Next by thrust pin 5, supporting pin 6, crank 6, passive push rod 7, constitute " thick stick Linkage " beginning action, one end of the throw crank 6 of passive push rod 7 travels forward, and the other end of crank 9 is rotated up thrust The pull-up of pin 5, after the first sensor 3 of biography detects sensor target 13-3 in place, control system receives signal, controls small rail car Moved at the position B on the second track 17 by the position A on the first track 16, completed rail action;Then small rail car After completing rail, the control system control action of electric pushrod 11 drives active push rod 13 to reset, and passive push rod 15 utilizes spring 8 Restoring force complete reset;It is last during passive push rod 15 resets, " leverage " while action, most thrust pin at last 5 turn back in track 16, realize locking.
The rail bridge of the present invention, scientific structure, effect is obvious, it is easy to safeguards, can be widely used for small rail car and deposit in track Crossing in rail problem in the case of relative position difference.
In the present embodiment, the front end of the active push rod 13 is wedging circumferential face, is easy to active push rod 13 to insert and passively pushes away In the guiding cross-drilled hole 7-1 of bar fairlead 7.
