Description

A kind of Weighing module with girt

Technical field

The utility model relates to a kind of weighing devices, and in particular to a kind of Weighing module with girt can be applied to The electronic weighing appliances such as bunker scale, weighing belt, feed proportioning system and bulking system.

Background technique

At present the weighings such as metallurgy, chemical industry, petrochemical industry monitoring industry in, producer select weighing mode to metering or this material When the control of position, multiple Weighing modules can be mounted on to the bottom of ingredient, bulking system, in conjunction in other device automatic gauge tank bodies The weight or material position in portion, at present the Weighing module of similar this structure by tank interior stirring and and motor oscillating When be easy to be affected, such Weighing module will receive effect of the vertical force with horizontal force.Since this Weighing module does not have There is level guard, so the tank body on top can move, can there is stuck or even breaking-up Weighing module and connector, mould The accuracy of block work can reduce.

The upper and lower stress connector of traditional sensor is to be assembled by upper and lower arc surface with steel ball, is easy horizontal lateral Cause steel ball climbing to which impact zero error can be caused too big under the action of power, and attachment trim designs are excessively complicated, and And connector is to be easy collision deformation using rigid connection design, influenced stability.

Also there is the Weighing module with horizontal defencive function at present, in Patent No. CN201720375831.6 State's patent " overarm arm sensor Weighing module ", including the carrier, carrying pressure head, cantilever beam sensing set gradually from top to bottom Device and bottom plate, it is characterised in that: the free end of the cantilever beam sensor is equipped with bearing holes, and tumbler pressure head setting is being held It carries in hole, carrier the cover is above the free end of cantilever beam sensor, and carrying pressure head is embedded in the bottom of the loading plate of carrier Portion, carrying pressure head middle and lower part are set on tumbler pressure head, and bottom plate is equipped with left side plate, and cantilever beam sensor is arranged in bottom plate On be positioned between left side plate, be equipped with the parallel side plate being cooperatively connected with left side plate at left and right sides of the lower end of carrier, two Parallel side plate is respectively correspondingly arranged in the side of left side plate, by spacer pin by the left and right sides of the parallel side plate of carrier and bottom plate Plate links together.This Weighing module can effectively prevent the phenomenon that module is toppled at work, but for module institute It is not ideal enough that the horizontal lateral force and unbalance loading in all directions received play position-limiting action, and structure is complicated, and it is more inconvenient to install, and is tying It is also required further improvement on structure.

Summary of the invention

Technical problem to be solved in the utility model is to provide a kind of structure design conjunction for the above-mentioned state of the art The Weighing module with girt of reason can play position-limiting action to horizontal lateral force suffered by module and unbalance loading in all directions.

Technical solution adopted by the utility model to solve the above technical problems is as follows: a kind of weighing mould with girt Block, including top plate, carrier head, sensor and the bottom plate set gradually from top to bottom, it is characterised in that: the top plate and bottom plate it Between be equipped with one for playing the girt of position-limiting action to horizontal lateral force suffered by module and unbalance loading in all directions, leaned on bottom plate The side of nearly sensor fixing end is convexly equipped with the first pull rod fixed block, and top plate is arranged in above the free end of sensor and carrier head Be connected, the lower end surface of top plate is convexly equipped with the second pull rod fixed block, the left and right ends of girt pass through respectively oscillating bearing with First pull rod fixed block, the connection of the second pull rod fixed block, and movement of roof can be driven with the movement and limit of oscillating bearing And limit.

As an improvement, the left and right ends of girt, the upper surface of the first pull rod fixed block is arranged in the oscillating bearing And second pull rod fixed block lower end surface be separately formed for oscillating bearing positioning positioning surface, oscillating bearing be equipped with center Hole is convexly equipped with connecting column corresponding with centre bore in the middle part of positioning surface, and oscillating bearing is rotatably arranged in across connecting column It is limited on positioning surface and by the cooperation of nut and connecting column and is fixed.

It is preferred that the positioning surface is the inner concave arc surface matched with oscillating bearing.

As an improvement, the side between the top plate and bottom plate far from sensor fixing end is equipped with overturning-preventing limit spiral shell Column, overturning-preventing limit stud are equipped with using the preceding locking nut locked to module.

It improves again, the carrier head is connected with the free end of sensor, positioned at the bearing point of sensor on bottom plate Lower section is equipped with an antioverloading stop screw.

Further, the fixing end of the sensor is equipped with mounting hole, and bottom plate is equipped with corresponding through-hole, and sensor is consolidated Between fixed end and bottom plate be equipped with a backing plate, backing plate be equipped with corresponding installation through-hole, by screw rod by the fixing end of sensor, pad Plate is fixed on bottom plate.

Further, the outside of the fixing end of the sensor is equipped with the connector for extraction wire.

Finally, the top plate side is equipped with the first threaded hole, the upper end of bottom plate is equipped with corresponding second threaded hole, passes through one Z-shaped connection sheet links together the second threaded hole and the first threaded hole.

Compared with the prior art, the advantages of the utility model are: girt is set between top plate and bottom plate, it is horizontal Pull rod is connected and fixed using the cooperation of oscillating bearing and pull rod fixed block with bottom plate, top plate, and the movement and limit of oscillating bearing are passed through The sports limiting direction of controlled level pull rod is come in position, and then plays limit to horizontal lateral force suffered by module and unbalance loading in all directions Effect；Antioverloading stop screw is set, the function of overload protection may be implemented；Overturning-preventing is set and limits stud, plays overturning-preventing Protective effect.The utility model is simple and reasonable, quick and easy for installation, and stability in use is good, and measurement accuracy is high, can effectively support The horizontal lateral force and other position-limiting actions in all directions that the module that disappears is subject to have the function of to overload position limitation protection, can be applied to expect Struggle against the electronic weighing appliances such as scale, weighing belt, feed proportioning system and bulking system.
