Description
Technical field
The utility model belongs to limiting device field, is related to a kind of travel switch, has overtravel more particularly, to one kind
The stroke switchgear of function.
Background technique
Travel switch, one kind of position switch (also known as limit switch) are a kind of common low current master control electrical apparatus.It utilizes
The collision of manufacturing machine moving component makes its contact action to realize connection or disjunction control circuit, reaches certain control mesh
's.In general, this kind of switch is used to position or the stroke of limit mechanical movement, keep movable machinery automatic by certain position or stroke
Stopping, counter motion, variable motion or automatic back and forth movement etc..Travel switch may be mounted at opposing stationary object (as admittedly
Determine frame, doorframe etc., abbreviation still life) on or movement object (such as drive a vehicle, door, abbreviation animal) on.When animal is close to still life
When, the contact of the connecting rod driving switch of switch causes the junction closure of contact disjunction or the disconnection of closure.Opened by make and break contact,
The movement of control circuit and mechanism is gone in the change of conjunction state.
Since the movement of Direct Action Type travel switch is simple and reliable, thus mechanical stroke in the prior art switch is usually straight
Dynamic formula travel switch, operating principle is similar with button, except that：One is manually, another is then by moving component
Collision block collision.When the collision block bruising button on extraneous moving component makes its contact action, after moving component leaves, make in spring
Under, contact automatically resets.But when stopping control of this travel switch for piling suspension transport trolley group, for a long time
It uses, the contact of travel switch is often collided with collision block, reduces the reliability used, and piling suspension transport trolley group
Inertia is larger, stops braking and needs braking distance, the contact movement travel of existing Direct Action Type travel switch is shorter, is not able to satisfy
Use demand.
Summary of the invention
The purpose of this utility model is exactly to provide a kind of for accumulating to overcome the problems of the above-mentioned prior art
The stroke switchgear of formula suspension transport trolley group.
The purpose of this utility model can be achieved through the following technical solutions：
A kind of stroke switchgear for piling suspension transport trolley group is set to piling suspension transport trolley group
Preceding trolley on, including：
Mounting bracket,
Sensor by the sensor body being fixed in mounting bracket and is set to sensor body bottom and can be vertical
The moving contact composition acted on direction,
Trigger board is rotatably connected in mounting bracket, and top is equipped with groove, is equipped with retainer, top on front side of top
Rear side is in using the center of rotation of trigger board as the arc in the center of circle, and bottom rear is equipped with counterweight part,
Limited block is set in mounting bracket, and is located above retainer, when the top of retainer is contacted with limited block
When, the center of rotation of moving contact, groove and trigger board on a vertical line, and the bottom end of moving contact support in a groove.
Preferably, the sensor is Direct Action Type travel switch.
Preferably, the moving contact includes actuating strut and the rotating wheel that actuating strut bottom is arranged in.
Preferably, the groove is arc groove, and groove is excessively gentle with top rear.

The distance of center of rotation.
Preferably, collision block arrives at a distance from trigger board center of rotation at the collision of trigger board and turns for bottom portion of groove to trigger board
5~20 times of the distance at dynamic center.
The working principle of the utility model is：When the device is not collided with the collision block of fixed setting, in the effect of counterweight part
Under, trigger board rotates around it center rotating, and the top of retainer is contacted with limited block, the rotation of moving contact, groove and trigger board
Center on a vertical line, and the bottom end of moving contact support in a groove；When the device and the collision block of fixed setting collide, hit
Block acts on trigger board lower part from front, and trigger board rotation, retainer limited block disengages, moving contact with trigger board rotate from
It skids off, is acted in groove, connect or disjunction control circuit, piling suspension transport trolley group are braked, braking process
In, trigger board continues to rotate, and moving contact is contacted with arc-shaped top rear, since top rear is in the rotation of trigger board
The heart is the arc in the center of circle, and moving contact stopping movement in braking process is played the role of protecting travel switch.
Compared with prior art, the utility model has the advantages that：
(1) clever structure, reliable operation.The utility model (can be with come trigger sensor using the trigger board specially designed
Using linear travel switch), the use stroke to form switch is expanded by the transmission of trigger board, is made it suitable for as product
The control for brake of formula suspension transport trolley group is put, sensor uses existing linear travel switch.It enhances to be formed out
Close the reliability of work.
(2) has the function of overtravel.Top rear is in using the center of rotation of trigger board as the arc in the center of circle, so that accumulative and travel type
It hangs in transport trolley group braking process, the moving contact for being able to maintain travel switch is failure to actuate, to play protection travel switch
Effect, so that the device is had overtravel function.
(3) auto-reset function.By being set to the counterweight part of bottom rear, trigger board is made to have auto-reset function,
In addition linear travel switch itself can automatically reset, so that the device be made to have auto-reset function.
