Description
Technical field
It the utility model is related to a kind of buffer-type anticollision mechanism for dynamic automobile scale.
Background technology
Dynamic automobile scale is the weight calculation equipment that dynamic weighing is carried out to the vehicle that misses the stop that freeway toll station generally uses,
Generally connected and formed by three sections or four section scale body phases.When vehicle enters scale body, due to the process meeting such as speed, load-carrying, brake
Impact of the vehicle to scale body is caused, drives scale body to rush forward or backward, makes scale body that parallel shifted occur, influences weighing precision.For
Ensure the stability of scale structure, avoid scale body is front and rear from shifting, caging bolt is reserved before and after present scale body in termination, on scale head
Pre-buried Crashworthy plate on the foundation ditch wall of road bed.When scale body is moved forward or rearward formula, caging bolt with scale body forward or to
After move, hit pre-buried Crashworthy plate, prevent scale body from continuing to be moved forward or rearward, maintain the in a basic balance of scale body.Usually, limit
For position bolt apart from Crashworthy plate distance about 5mm, scale body and surrounding foundation ditch are contactless, avoid gravity from being unloaded.
Because vehicle is very big to scale body impulsive force, shock of this caging bolt to Crashworthy plate is strongly and is straight
Rush formula, without any buffering, often cause scale body collide forward or backward after caging bolt it is stuck, scale body can not reply original
Position, causes the weight of vehicle to be let out power because scale body is stuck, weighs inaccurate, can not normal work.
Utility model content
The purpose of this utility model is to provide a kind of buffer-type anticollision mechanism for dynamic automobile scale, can mitigate dynamic vapour
Car weighing apparatus scale body caused by motor racing and basic impulsive contact force in weighing process.
To achieve the above object, the technical solution adopted in the utility model is：A kind of buffer-type for dynamic automobile scale
Anticollision mechanism, including scale body and buffer gear, the buffer gear are arranged on the scale body, and the buffer gear includes spacing
Bolt, helical spring, damping limited block, limiting bracket and adjustable stroke nut, the damping limited block and the spacing branch
Frame is fixedly connected, and the damping limited block is provided with through hole, the screw rod of the caging bolt pass through the through hole with it is described adjustable
Save stroke nut to coordinate, the internal diameter of the through hole is engaged with the external diameter of screw rod, and the helical spring passes through the caging bolt
Screw rod and positioned at it is described damping limited block and caging bolt termination between, one end of the limiting bracket is fixed with the scale body
Connection.
Preferably, one end of the limiting bracket is welded on the scale body.
Preferably, the helical spring is high strength helical spring.
Buffer-type anticollision mechanism adjustable limit stroke of the present utility model, available buffer, can Self-resetting, dynamic vapour can be mitigated
Car weighing apparatus scale body caused by motor racing and basic impulsive contact force in weighing process, keep scale body balance, reduce signal interference intensity,
Improve weighing precision.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
In figure, 1, scale body, 2, caging bolt, 3, helical spring, 4, damping limited block, 5, limiting bracket, 6, adjustable row
Journey nut, 7, through hole.
Embodiment
The utility model is described in further detail with specific embodiment below in conjunction with the accompanying drawings.
As shown in figure 1, a kind of buffer-type anticollision mechanism for dynamic automobile scale of the present utility model, including the He of scale body 1
Buffer gear, the buffer gear are arranged on the scale body 1, and the buffer gear includes caging bolt 2, helical spring 3, resistance
Buddhist nun's limited block 4, limiting bracket 5 and adjustable stroke nut 6, the damping limited block 4 are fixedly connected with the limiting bracket 5,
The damping limited block 4 is provided with through hole 7, and the screw rod of the caging bolt 2 passes through the through hole 7 and the adjustable stroke spiral shell
Mother 6 coordinates, and the internal diameter of the through hole 7 is engaged with the external diameter of screw rod, and the helical spring 3 passes through the spiral shell of the caging bolt 2
Bar is simultaneously damped between limited block 4 and the termination of caging bolt 2 positioned at described, and one end of the limiting bracket 5 is fixed with the scale body 1
Connection.
Preferably, one end of the limiting bracket 5 is welded on the scale body 1.
Preferably, the helical spring 3 is high strength helical spring.
Caging bolt 2 determines that caging bolt 2 stretches out limiting bracket through damping limited block 4 by adjustable stroke nut 6
5 length, to adjust the gap of caging bolt 2 and foundation ditch Crashworthy plate, helical spring 3 be assemblied in damping limited block 4 with it is spacing
Between the termination of bolt 2, its flexible crucial machine for being limited by limit damping block 4 and the termination of caging bolt 2, being whole buffering and reply
Structure.When scale body 1 moves forward, the termination of caging bolt 2 collision Crashworthy plate, by resistance, the forced compression of helical spring 3, spacing spiral shell
Bolt 2 moves to the direction of scale body 1, and scale body 1 slow down impulse force because of the effect of helical spring 3.When scale under vehicle or it is static when, scale body 1
Forward momentum disappears, the distress resolves of helical spring 3, because elastic deformation recovers, promotes the shift reverse of scale body 1, recovers normal shape
State, equally because the effect of helical spring 3 slow down amplitude, the vibrations of scale body 1 are reduced, ensure that the steady of weighing sensor
It is qualitative, the quality of weighing-up wave is improved, improves weighing precision.
