Abstract
The utility model relates to a novel steel-making feeding hopper scale automatic verification device. The automatic verification device comprises a support platform disposed on side walls of a weighing device and an electric hydraulic rod. One end of the electric hydraulic rod is fixedly connected to the support platform, and the other end of the electric hydraulic rod is connected with a counterweight via a steel wire rope. The measuring range of a rapid verification device of the weighing device is 1 ton, and the weight of each counterweight is 500kg. According to the automatic verification device, the verification precision of the weighing hopper is effectively improved.
Description
Technical field
The utility model relates to a kind of device and method of Novel steelmaking material loading bunker scale automatic Verification, relates in particular to a kind of raising scale hooper weighing precision, safe automatic check device and method.
Background technology
Steelworks need to arrange a large amount of electric furnaces, is furnished with corresponding LF refining furnace and VD refining furnace simultaneously, and charging method refers to from ground blanking bin to steel scrap high hopper and the method for electric furnace, LF stove high hopper feed.The workflow of whole charging method is roughly as follows: the other bucket → feed opening that gathers of supplied materials → automobile blow tank → high spud angle sealing-tape machine → dump car → high hopper → weighing bucket → stove.
In prior art, the other hopper of electric furnace is not installed weigher, in gage work process, can only patrol and examine by staff scene, or terminal, on-the-spot display show the metering method fault that extremely judges meausring apparatus, in the use procedure of meausring apparatus weigher, need regularly it to be carried out to verification.And verification mode of the prior art needs, field personnel is free-hand to remove counterweight to the enterprising rower of weighing bucket and determines verification, verification general assembly (TW) according to 1 ton, need to prepare at the scene the counterweight of 40 25kg, if increase again counterweight weight, manpower transport is very inconvenient, be time-consuming effort again, also take very much site space simultaneously, operate and also there is larger potential safety hazard.
Utility model content
Technical problem to be solved in the utility model is, overcomes the shortcoming of prior art, and a kind of Novel steelmaking material loading automatic calibration device for hopper scale is provided, and improves the weighing precision of scale hooper, for field personnel and STEELMAKING PRODUCTION facilitate.
In order to solve above technical matters, the utility model relates to a kind of Novel steelmaking material loading automatic calibration device for hopper scale, comprise the support platform and the electric hydaulic bar that are arranged on meausring apparatus sidewall, electric hydaulic bar one end is fixedly connected in support platform, and the electric hydaulic bar other end is connected by wire rope with counterweight.
The technical scheme further limiting is: the range of the quick checker of meausring apparatus is 1 ton, and the weight of its each verification counterweight is 500kg.
The beneficial effects of the utility model are: use automatic check device can improve the weighing precision of scale hooper, the working strength that counterweight has alleviated employee without dismounting has simultaneously improved the security of working simultaneously, to applying unit, has saved a large amount of spaces.
Accompanying drawing explanation
Service chart when Fig. 1 is the normal operation of the utility model automatic checker.
Service chart when Fig. 2 is the utility model automatic checker verifying work.
Embodiment
embodiment 1
The present embodiment provides a kind of Novel steelmaking material loading bunker scale quick verification detection method, Fig. 1 and Fig. 2 are the service chart of automatic checker when normal operation and verifying work in method, comprise the support platform 4 being arranged on meausring apparatus both sides, in described support platform 4, be provided with electric hydaulic bar 1, described electric hydaulic bar 1 one end is fixedly connected in support platform 4, and described electric hydaulic bar 1 other end is connected by wire rope 2 with counterweight 3.
When metering system works, electric hydaulic bar 1 is not worked, and counterweight 3 is placed in ground, and wire rope 2 does not bear the gravity of counterweight 3.
When metering system verification, electric hydaulic bar 1 receives that the driving of motor hangs ground by counterweight 3, and 1 ton of counterweight loads on meausring apparatus, realizes the verification of bunker scale.
The utility model it should be noted that while using:
(1) support platform is fixedly connected on described scale hooper sidewall, and support platform is reinforced need pass through Stromeyer test.(2) scale hooper quick checking device verification weight is 1 ton, and on scale hooper quick checking device, the weight of verification counterweight is 500kg.(3) during the not verification of verification counterweight without unloading, maintain and be placed in ground
In addition to the implementation, the utility model can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
Claims (2)
1. the device of a Novel steelmaking material loading bunker scale automatic Verification, it is characterized in that: comprise the support platform and the electric hydaulic bar that are arranged on meausring apparatus sidewall, described electric hydaulic bar one end is fixedly connected in support platform, and the described electric hydaulic bar other end is connected by wire rope with counterweight.
2. according to described in claims 1, it is characterized in that: the range of the quick checker of described meausring apparatus is 1 ton, the weight of its each verification counterweight is 500kg.
