Abstract

The utility model provides a protective baffle plate device for automobile weigher sensors. The baffle plate device is fixed on a weigher body, a plurality of the automobile weigher sensors are uniformly distributed on the weigher body, the side surface of each automobile weigher sensor is provided with a protective baffle plate, and each protective baffle plate is fixed on the weigher body through connecting and fixing bolts. The effects of the protective baffle plate device for the automobile weigher sensors are that after the protective baffle plates are added to the automobile weigher sensors, the foreign material amount at the positions of the sensors is obviously reduced, coverage, erosion and abrasion of the sensors caused by coal ash and dirt are reduced, damages of the sensors are reduced, the equipment maintenance cost is reduced, and the sensors can be maintained and cleaned conveniently only by dismounting the protective baffle plates. By adding protective baffle plates to the weighing sensors, the weighing sensors can be protected from foreign materials, dust and the like, and the weighing precision is improved. The added protective baffle plates can protect the sensors, because the price of the sensors is high, when the sensors are protected, the equipment maintenance cost can be reduced, and at the same time the influence on weighing precision is reduced.

Description

Truck scale sensor protective baffle plate device

Technical field

The utility model relates to a kind of protective device, especially for vehicle weighing-appliance sensor dustproof protective device.

Background technology

Truck scale is as a kind of weight utensil of large cargo, be widely used in the industries such as communications and transportation, port logistics, comprise that three claim plate, by three, claiming plate to claim overlap joint to form whole title body level is also evenly provided with a plurality of LOAD CELLS, is Cheng Banyucheng plate lap-joint's sensor position as shown in Figure 1,3.This large-scale weighing machine symmetric body good stability, the weighing precision of sensor is high.The installation of sensor: the mounting plane of single LOAD CELLS mounting seat will be adjusted level with level meter; A plurality of LOAD CELLS mounting seat mounting planes will be adjusted on a surface level as far as possible, relative error is at 3-5 millimeter, and object is that the load that each LOAD CELLS is born is basically identical, and sensor should be put by vertical 90 degree, the heeling condition that do not have, can cause weighing data incorrect.

In actual production operation, truck scale sensor is long-term outside exposed, because site work environment is severe and sleety weather very easily causes foreign material, coal ash accumulation of mud covering sensor and external force factor and then affect the accuracy of weighing data.Coal ash dirt causes heavy wear and damage to sensor after entering sensor holder, increases cost of equipment maintenance.

Summary of the invention

For the long-term exposed problem that exposed outside of truck scale sensor; the purpose of this utility model is to provide a kind of truck scale sensor protective baffle plate; be beneficial to be reached for the effect that sensor obtains proofing dust and protecting, external factor is dropped to minimum effect to the damage of sensor.

For achieving the above object, the technical solution adopted in the utility model is to provide a kind of truck scale sensor protective baffle plate device, this retaining device is fixed on and claims on body, on described title body, be evenly equipped with a plurality of truck scale sensors, wherein: described each truck scale sensors sides is equipped with protective baffle plate, protective baffle plate claims on body by being connected and fixed to be bolted to.

Effect of the present utility model is that truck scale sensor is installed additional after protective baffle plate, and sensing station foreign material amount obviously reduces, and reduces coal ash dirt to the covering of sensor, erosion and wearing and tearing.Be conducive to lower sensor and damage, reduce cost of equipment maintenance, safeguard aspect clean also very easy, as long as protective baffle plate is pulled down and just can be safeguarded and clean.

Embodiment

Below in conjunction with accompanying drawing, truck scale sensor protective baffle plate structure of the present utility model and installation are illustrated

As shown in Figure 2,4, truck scale sensor protective baffle plate device of the present utility model, this retaining device is fixed on and claims on body, described title body is three and claims the combination side by side of plate overlap joint, on whole title body, both sides are evenly equipped with totally eight of sensors, described retaining device is the protective baffle plate 3 that shape is identical, every protective baffle plate 3 is fixed on and claims on body, sensor to be protected by being connected and fixed bolt 4, claims body middle part to claim plate overlap joint to install a protective baffle plate 3 additional with integrated connection and is fixed every with bolt to claim plate owing to existing.Totally eight sensors of symmetric body both sides install respectively protective baffle plate 3 additional.

By outside being installed additional to protective baffle plate 3, come, to sensor whole proofing dust and protecting in addition, to reduce external force and the secondary injury of coal dust dirt to sensor.As shown in Figure 3, truck scale sensor protective baffle plate 3 of the present utility model is that under pin symmetric body, each sensor is that 320mm*315mm steel plate is installed at sensor outside by a block specifications, form integral protection, and claim on body with being connected and fixed to be bolted to, two bolts are at a distance of 180mm, and 45mm place, fixed position baffle plate top structure comprises: protective baffle plate 3, be connected and fixed bolt 4.By truck scale sensor outside being installed additional to baffle plate, come, to sensor whole proofing dust and protecting in addition, to reduce external force and the secondary injury of coal dust dirt to sensor.

Truck scale sensor protective baffle plate device of the present utility model is arranged on sensor outside and has avoided the severe and sleety weather of site work environment easily to cause foreign material, coal ash accumulation of mud covering sensor.Especially for manufacturing LOAD CELLS with aluminum alloy materials, any impact, fall, to the performance of LOAD CELLS itself, all can cause very big infringement; For jumbo LOAD CELLS, in general there is larger deadweight, truck scale sensor protective baffle plate device is protected effectively.

Claims

1. a truck scale sensor protective baffle plate device, this retaining device is fixed on and claims on body, on described title body, be evenly equipped with a plurality of truck scale sensors, it is characterized in that: described each truck scale sensors sides is equipped with protective baffle plate, protective baffle plate claims on body by being connected and fixed to be bolted to.
