Abstract
Description
Technical Field
[0001] This utility model relates to a converter steelmaking auxiliary lance probe recovery device, belonging to the technical field of steelmaking equipment in the metallurgical industry. Background Technology
[0002] The auxiliary lance can effectively improve the production efficiency of the converter, reduce the intensity of manual labor, and enable the converter to perform functions such as temperature measurement, sampling, and liquid level measurement without tilting the furnace. The auxiliary lance probe, as the measuring element of the auxiliary lance, works in conjunction with the auxiliary lance to complete functions such as temperature measurement and sampling. Existing auxiliary lance designs all include two aspects: the converter oxygen lance platform operating surface and the furnace back operating surface. The oxygen lance platform operating surface includes the auxiliary lance APC operating box and the probe recovery chute. The furnace back operating surface includes the chute platform and the furnace back operating box. When the auxiliary lance causes a probe connection abnormality in the current furnace due to steel adhesion, slag adhesion, or other abnormal reasons, the existing handling measures are: ① By setting an auxiliary lance reset function, the auxiliary lance probe is removed from the oxygen lance platform operating surface. After reset, the auxiliary lance probe automatically falls from the recovery chute to the furnace back operating surface. This operation will damage the auxiliary lance probe of this furnace, rendering it unusable. ② The operator moves from the furnace rear operating surface to the oxygen lance operating surface and manually removes the probe using the reset function. This operation requires manual climbing of 15-20 meters, and the oxygen lance operating surface has a high gas content year-round, increasing the labor intensity and posing significant safety risks. ③ Lowering the auxiliary lance to the furnace rear platform requires one operator to move the auxiliary lance upwards while another operator holds the auxiliary lance probe and pulls it out. Because the auxiliary lance may have adhered steel or slag, and the insertion and extraction force between the probe and the auxiliary lance exceeds 50N, the operator holding the probe risks not only failing to remove it but also falling and injuring themselves from the adhered steel or slag. Utility Model Content
[0003] The purpose of this invention is to provide a converter steelmaking auxiliary lance probe recovery device that can quickly, independently, and safely recover auxiliary lance probes on the converter platform, thereby avoiding waste of auxiliary lance probes, reducing the labor intensity of employees, and preventing safety accidents caused by manually pulling out auxiliary lance probes.
[0004] The technical solution of this utility model is: A converter steelmaking auxiliary lance probe recovery device includes a handle, a pull rod sleeve, a pull rope, a trolley, and a clamp. The pull rod sleeve is fixed on the trolley, and the pull rope is disposed inside the pull rod sleeve. One end of the pull rope is connected to the handle, and the other end of the pull rope is connected to the clamp. The clamp includes a pull rope sleeve connector, short connecting rods, connecting bolts, an adjusting spring, long connecting rods, and clamping plates. There are two identical short connecting rods, long connecting rods, and clamping plates. One end of each of the two short connecting rods is hinged to the pull rope sleeve connector, and the other ends of each of the two short connecting rods are respectively connected to one end of each of the two long connecting rods via connecting bolts. The other ends of each of the two long connecting rods are respectively provided with clamping plates that cooperate with the auxiliary lance probe. The two long connecting rods are rotatably connected together in the middle, and the adjusting spring is disposed between the two long connecting rods.
[0005] The clamping plate in the holder is an arc-shaped plate that mates with the secondary gun probe.
[0006] The two long connecting rods in the clamp are rotatably connected together by a pin.
[0007] The adjusting spring in the clamp is located near one end of the short connecting rod.
[0008] The pull rod sleeve is fixed horizontally on the trolley.
[0009] The beneficial effects of this utility model are: it enables the rapid, single-person, and safe retrieval of the secondary lance probe on the converter platform, avoiding waste of the secondary lance probe, reducing the labor intensity of employees, and avoiding safety accidents caused by manually pulling out the secondary lance probe. Moreover, the device can be reused multiple times. Attached Figure Description

[0011] The present invention will be further described below with reference to the accompanying drawings and examples.
[0012] See attached document Figure 1-4A converter steelmaking auxiliary lance probe recovery device includes a handle 1, a pull rod sleeve 3, a pull rope 4, a trolley 5, and a clamp 6. The pull rod sleeve 3 is fixed on the trolley 5. The pull rope 4 is disposed inside the pull rod sleeve 3. One end of the pull rope 4 is connected to the handle 1, and the other end of the pull rope 4 is connected to the clamp 6. The clamp 6 includes a pull rope sleeve connector 7, short connecting rods 8, connecting bolts 9, adjusting springs 10, long connecting rods 11, and clamping plates 12. There are two identical short connecting rods 8, long connecting rods 11, and clamping plates 12. One end of the two short connecting rods 8 is hinged to the pull rope sleeve connector 7. The other ends of the two short connecting rods 8 are respectively connected to one end of the two long connecting rods 11 through connecting bolts 9. The other ends of the two long connecting rods 11 are respectively provided with clamping plates 12 that cooperate with the auxiliary lance probe. The middle of the two long connecting rods 11 is rotatably connected together. The adjusting spring 10 is disposed between the two long connecting rods 11.
[0013] In this embodiment, refer to the appendix Figure 1-4 A converter steelmaking auxiliary lance probe recovery device includes a handle 1, a trolley handle 2, a pull rod sleeve 3, a pull rope 4, a trolley 5, and a clamp 6, wherein: The pull rod sleeve 3 is fixed horizontally on the trolley 5.
[0014] The clamp 6 includes a pull rope sleeve connector 7, short connecting rods 8, connecting bolts 9, adjusting springs 10, long connecting rods 11, and clamping plates 12. The pull rope sleeve connector 7 is connected to the pull rope 4. There are two identical short connecting rods 8, long connecting rods 11, and clamping plates 12. The clamping plates 12 are arc-shaped plates that cooperate with the sub-gun probe. One end of each of the two short connecting rods 8 is hinged to the pull rope sleeve connector 7. The other end of each of the two short connecting rods 8 is connected to one end of each of the two long connecting rods 11 through connecting bolts 9. The other end of each of the two long connecting rods 11 is provided with a clamping plate 12. The middle of the two long connecting rods 11 is rotatably connected together by a pin. The adjusting spring 10 is located between the two long connecting rods 11 and close to one end of the short connecting rod 8.
[0015] During use, if the operator finds that the auxiliary gun probe is not properly connected, the auxiliary gun is lowered to the platform behind the furnace via the operating surface. The auxiliary gun probe recovery device is then pushed to the auxiliary gun body, and the clamp 6 is used to hold the auxiliary gun probe 13. The pull rope 4 is pulled by the handle 1 to tighten the clamp 6 around the auxiliary gun probe 13. At the same time, the auxiliary gun system's lifting function is activated to raise the auxiliary gun body 14, thus separating the auxiliary gun probe 13 from the auxiliary gun body 14 and achieving the recovery of the auxiliary gun probe. After the auxiliary gun probe 13 is separated, the handle 1 is released, and the clamp 6 automatically releases, completing the recovery of the auxiliary gun probe 13.
