Highway weighing scale prevent floating stop device, it is fixed to play the tractive when ponding is more or rivers are great, set for activity limit 5 ~ 10mm from top to bottom, do not cause the weighing platform drift to make accessories such as sensors dislocate when ponding is more, cause the damage of the title body and device.
Description
Technical Field
The utility model belongs to the technical field of highway weighing scale, especially, relate to highway weighing scale anti-floating stop device.
Background
In the design and use process of the weight-measuring equipment for the toll lane of the highway toll station, after a large amount of accumulated water in the toll lane is not considered, the weight-measuring equipment floats due to buoyancy of water and is displaced due to water flow, so that devices such as a weighing platform and a sensor and cables are damaged.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a highway weighing scale prevents floating stop device to solve the problem that proposes among the above-mentioned background art.
In order to achieve the above object, the utility model provides a following technical scheme:
highway weighing scale anti-floating stop device, including backup pad and lower bolster, four rag bolts are evenly installed in lower bolster four corners, still including installing the preceding upper bracket of backup pad, the upper bracket both ends symmetry is provided with two bolt assembly, install the round pin axle in the middle of the upper bracket, round pin axle one end is provided with the split pin, the round pin axle rotates installs joint bearing, joint bearing bottom welding has lock nut, install down the pull rod in the middle of the lock nut, the pull rod circumference is provided with the protective sheath down, the pull rod bottom is provided with the base, the pedestal mounting be in on the lower bolster, down the pull rod with base sliding connection.
Further: the support plate is L-shaped.
Further: the pin shaft is made of No. 45 steel.
Further: the screwing length of the knuckle bearing and the lower pull rod is 10-15 mm.
Compared with the prior art, the beneficial effects of the utility model are that:
the scale is pulled and fixed when the accumulated water is more or the water flow is larger, the upper and lower movement limits are set to be 5-10 mm, so that the scale platform drifts to cause the parts such as the sensor to be dislocated when the accumulated water is more, and the scale body and the device are not damaged.

Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1-4, the anti-floating limiting device of the highway weighing scale comprises a supporting plate 1 and a lower backing plate 11, four foundation bolts 12 are uniformly installed at four corners of the lower backing plate 11, the anti-floating limiting device further comprises an upper support 2 installed in front of the supporting plate 1, two bolt assemblies 5 are symmetrically arranged at two ends of the upper support 2, a pin shaft 4 is installed in the middle of the upper support 2, a split pin 3 is arranged at one end of the pin shaft 4, a joint bearing 6 is rotatably installed on the pin shaft 4, a locking nut 7 is welded at the bottom of the joint bearing 6, a lower pull rod 9 is installed in the middle of the locking nut 7, a protective sleeve 8 is arranged on the circumference of the lower pull rod 9, a base 10 is arranged at the bottom of the lower pull rod 9, the base 10 is installed on the lower backing plate 11, and the lower pull rod 9 is slidably connected with the base 10.
Further: the supporting plate 1 is L-shaped, so that the strength of the supporting plate 1 is increased; the pin shaft 4 is made of No. 45 steel, so that the pin shaft 4 is firm; the screwing length of the knuckle bearing 6 and the lower pull rod 9 is 10-15 mm, so that the adjustment is convenient as required.
The working principle is as follows: fix four lower bolster 11 respectively subaerial through rag bolt 12, then weld four backup pads 1 respectively on weighing platform balance head four corners side, through the rotatory lower link 9 of protective sheath 8, adjust the meshing length of lower link 9 and joint bearing 6 under lock nut 7's meshing to guarantee weighing platform balance head level, lower link 9 slides freely in base 10 when ponding is more or rivers are great, and it is fixed with joint bearing 6 tractive weighing platform balance head together.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
