Background technique
The railway transportation used inside industrial enterprise is usually low-speed run state.Traditional point tongue pull rod designs
The pin Fixed frog two sides point of switch is worn using steel plate, completes turnover lane change by tongue control railway switch sliding.It is transported in locomotive
Row railway switch tongue region, trainman is when railway switch track switch operates and tongue control railway switch fault recognition is made mistakes, road
For trouble under locking states, locomotive passes through switch zones from opposite direction, reverse by locomotive wheel under route error running state
Promotion point tongue drives pull rod, will lead to tongue pushing drawing rod and destroys point tongue control railway switch, causes to squeeze track switch and take off
Rail accident makes route outage, and will cause track switch equipment and following damage occurs: 1, point tongue pushing drawing rod makes tongue
Controller central axis torsional deformation rotational angle generates variation and is not available；2, tongue pushing drawing rod and control railway switch central axis
Connection positioning pin twists off；3, tongue deformation damage.
Utility model content
The purpose of this utility model is that aiming at the disadvantages of the prior art, providing a kind of anti-extrusion promotion of point tongue anticollision
Device can avoid trainman in the operation of railway switch track switch or tongue control railway switch fault recognition fault using the pusher
Shi Zaocheng squeezes track switch and locomotive derailment accident.
Problem described in the utility model is solved with following technical proposals:
A kind of anti-extrusion pusher of point tongue anticollision, including pushing drawing rod positioning plate, tongue controller pull rod fixed frame and
Buffer spring, the distance between the length of the pushing drawing rod positioning plate and two tongues match, and the tongue controller pull rod is solid
Determine the middle part that frame is located at pushing drawing rod positioning plate, the buffer spring is equipped with two, and two buffer springs are located at tongue control
The two sides of device pull rod fixed frame processed, each buffer spring both ends press tongue controller pull rod fixed frame, pushing drawing rod positioning respectively
Plate.
The above-mentioned anti-extrusion pusher of point tongue anticollision, the both ends of the pushing drawing rod positioning plate are respectively equipped with spring retainer
Chamber, it is intracavitary that the outboard end of each buffer spring is located at spring retainer.
The above-mentioned anti-extrusion pusher of point tongue anticollision, the tongue controller pull rod fixed frame are connected equipped with switch rod
Plate, switch rod connecting plate and switch rod sell axis connection.
The two sides of the above-mentioned anti-extrusion pusher of point tongue anticollision, the tongue controller pull rod fixed frame are respectively and fixedly connected with spring
Limit shaft, the inner end of each buffer spring are set on spring retainer axis.
The above-mentioned anti-extrusion pusher of point tongue anticollision, the both ends of pushing drawing rod positioning plate are equipped with connecting plate, each connecting plate point
It is not connect with tongue.
The utility model is mounted at track switch between two tongues, and the pusher can be used as when railway operation is normal
The connecting rod that branches off uses；When the operation of trainman's track switch and point switch fault recognition are made mistakes, track switch is under locking states, machine
When vehicle passes through switch zones from opposite direction, locomotive wheel inversely pushes point tongue, and the utility model can drive tongue at this time
It is mobile, pass through locomotive safety switch zones, locomotive in the case where not damaging point tongue and control railway switch equipment
The utility model can drive tongue to automatically reset by the retractility of spring afterwards, to efficiently solve due to operation error and set
Track switch accident is squeezed caused by standby failure, is avoided because locomotive derailing slides down caused by squeezing track switch.The utility model is designed reasonably, structure
Simply, easy to adjust, safe and reliable.
Detailed description of the invention
The utility model is described in further detail with reference to the accompanying drawing.
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 Fig. 1 top view；
Fig. 3 is the perspective view of the utility model；
Fig. 4 is the utility model use state diagram.
Each label in figure are as follows: 1, connecting plate, 2, spring retainer chamber, 3, pushing drawing rod positioning plate, 4, buffer spring, 5, tongue
Controller pull rod fixed frame, 6, spring retainer axis, 7, switch rod connecting plate, 8, switch rod, 9, tongue.
Specific embodiment
Referring to Fig. 1-Fig. 3, the utility model is suitable for the railway transportation of low speed factories and miness, and constituting includes pushing drawing rod positioning plate
3, tongue controller pull rod fixed frame 5 and buffer spring 4.The distance between the length of pushing drawing rod positioning plate and two tongues
Match, the both ends of pushing drawing rod positioning plate are equipped with the connecting plate 1 of evagination, and each connecting plate is connect with the tongue of two sides respectively.The point
Rail controller pull rod fixed frame is located at the middle part of pushing drawing rod positioning plate, and buffer spring 4 is equipped with two, two buffer spring difference
Positioned at the two sides of tongue controller pull rod fixed frame, each buffer spring both ends press tongue controller pull rod fixed frame respectively and push away
Dynamic pull rod positioning plate.Tongue controller pull rod fixed frame is equipped with switch rod connecting plate 7, switch rod connecting plate and switch rod
