The function of the slag sample extraction device is to obtain slag samples from the steelmaking process for analysis and testing. However, there are some limitations in the current extraction device. Firstly, the adjustable range on the surface of the extraction device is relatively narrow, which makes the use of the extraction device less convenient. Secondly, when extracting the current converter steelmaking slag sample, the sampling depth is limited to a certain extent, and it is difficult to measure accurately, thus affecting the extraction efficiency. These limitations pose certain challenges to effective extraction. Summary of the Utility Model

[0003] The purpose of the utility model is to address the deficiencies of the existing technology and provide a converter steelmaking slag sample extraction device that can solve the technical problem that the existing device is prone to damage the handheld rod during the process of taking out the sample.

[0004] To achieve the above purpose, the utility model provides a converter steelmaking slag sample extraction device, including:

[0005] An installation platform, with a cylinder body passing through the middle. A driving component is arranged between the installation platform and the cylinder body. When the driving component operates, it drives the cylinder body to move in the vertical direction.

[0006] An adjusting component, movably arranged on the outer periphery of the installation platform. The adjusting component includes multiple pairs of movable rods. A connecting rod and a connecting sleeve are arranged between each pair of movable rods. The two ends of the connecting rod are connected to the movable rods, and the connecting sleeve is screwed on the connecting rod. When the connecting sleeve is rotated, the distance between each pair of movable rods can be adjusted.

[0029] The preferred embodiments of the present utility model will be described in more detail below. Although the preferred embodiments of the present utility model are described below, it should be understood that the present utility model can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to make the present utility model more thorough and complete, and to fully convey the scope of the present utility model to those skilled in the art.

[0030] The present utility model provides a converter steelmaking slag sample extraction device, comprising:

[0031] An installation platform, with a cylinder body penetrating through the middle thereof. A driving component is arranged between the installation platform and the cylinder body. When the driving component operates, it drives the cylinder body to move in the vertical direction;

[0032] An adjusting component, which is movably arranged on the outer periphery of the installation platform. The adjusting component includes multiple pairs of movable rods. A connecting rod and a connecting sleeve are arranged between each pair of movable rods. The two ends of the connecting rod are connected to the movable rods, and the connecting sleeve is screwed on the connecting rod. When the connecting sleeve is screwed, the distance between each pair of movable rods can be adjusted;

[0033] An extraction component, which is arranged on the cylinder body. The extraction component includes a pull rod, a feed hole arranged at the lower end of the cylinder body, and an access opening arranged at the upper end of the cylinder body. The lower end of the pull rod moves between the feed hole and the access opening.

[0034] Specifically, a cylinder body is penetrated through the installation platform of the extraction device, and an adjusting component is arranged on the outer periphery of the installation platform. The placement height of the installation platform can be adjusted through the adjusting component, and the angle between the movable rod and the installation platform can be adjusted. After the installation platform is adjusted to a suitable height, the distance between each pair of movable rods is fixed through the connecting rod and the connecting sleeve between the movable rods. In this way, the movable rods will remain stable. The principle that the connecting sleeve controls the elongation length of the connecting rod is the same as the principle of adjusting the length of a telescopic rod; when the placement height of the installation platform is fixed, the cylinder body is controlled to be inserted into the slag through the driving component. When the lower end of the cylinder body reaches the sampling height, the slag at the lower end of the cylinder body can be sampled through the extraction component, and the clean and undamaged slag sample can be taken out from the access opening. In this way, the damage of the device can be effectively prevented.

[0035] Optionally, the driving component includes a driving gear and a driven gear that mesh with each other. The driving gear is arranged on a motor on the installation platform. An external thread is arranged on the outer periphery of the cylinder body, and the driven gear is sleeved on the outer periphery of the cylinder body and is matched with the external thread.

[0036] Specifically, the driving component is arranged between the installation table and the cylinder body. Through gear meshing transmission, the rotational force of the driving gear on the motor can be transmitted to the driven gear. Since the inner peripheral surface of the driven gear meshes with the external threads on the outer periphery of the cylinder body, the cylinder body can move downward through the synergistic effect with the external threads. The lower end of the cylinder body extends into the slag and reaches the sampling depth, effectively solving the problem of measuring the sampling depth. The synergistic effect of the entire system makes on-site sampling more efficient and accurate. In addition, the driving component is arranged on the upper side of the installation table, and there is an installation table between it and the slag, which can ensure the service life of the driving component.

[0037] Optionally, the adjusting component includes a rotating groove and a rotating shaft. A plurality of rotating grooves are evenly formed along the outer periphery of the installation table, the rotating shaft is rotatably arranged in the rotating groove, and the rotating shaft is rotatably connected to the upper end of the movable rod.

[0038] Specifically, the rotating groove is arranged on the outer periphery of the installation table. The number of rotating grooves is even. A rotating shaft is rotatably connected in the rotating groove, and the movable rod is rotatably arranged in the rotating groove through the rotating shaft. In this way, by changing the rotation angle of the rotating shaft, the movable rod forms different angles with the installation table, thereby realizing the height adjustment of the installation table.

[0039] Optionally, fixing blocks are symmetrically arranged on each pair of movable rods respectively, and both ends of the connecting rod are rotatably connected to the fixing blocks.

[0040] Specifically, in a pair of movable rods, fixing blocks are symmetrically arranged on each movable rod. A fixing rod is arranged on one side of the fixing blocks close to each other. The end of the connecting rod is inserted into the fixing rod, and the fixing rod and the connecting rod can be rotatably connected to each other.

[0041] In one embodiment, for the connecting rod and the connecting sleeve in the adjusting component, the connecting rod can be provided with two sub-connecting rods with opposite thread directions. The two sub-connecting rods are respectively arranged at both ends of the connecting sleeve, and each sub-connecting rod is threadedly connected to one end of the connecting sleeve. When it is necessary to shorten the distance between each pair of movable rods, the two sub-connecting rods are screwed into the interior of the connecting sleeve. When it is necessary to increase the distance between each pair of movable rods, the two sub-connecting rods are screwed out from the interior of the connecting sleeve. In this way, the adjustment method of this adjusting component is simple, improving the slag extraction work efficiency.

[0042] Optionally, a rotating rod penetrates through the lower end of the movable rod, and the rotating rod is connected to the cushion block through a rivet, and the rivet penetrates through the middle of the cushion block.

[0043] Specifically, the lower end of the movable rod is stably placed in the slag pile through the cushion block. When the surface of the slag is uneven, the height of each cushion block can be adjusted by screwing the rivet to ensure that the extraction device is placed stably and firmly during operation.

[0044] Optionally, a conical cap is arranged at the lower end of the cylinder body.

[0045] Specifically, when the driving component operates, the cylinder body inserts into the slag pile as the motor driving gear rotates. A conical cap is provided at the lower end of the cylinder body to reduce the resistance of the cylinder body entering the slag pile.

[0046] Optionally, a grip rod is provided at the upper end of the cylinder body, a limit sleeve is provided on the grip rod, a pull rod passes through the limit sleeve, and a grip ball is provided at the upper end of the pull rod. The grip ball is in snap-fit with the limit sleeve.

[0047] Specifically, a pull rod is provided in the cylinder body. The pull rod is slidably arranged on the limit sleeve, and the limit sleeve can limit the moving direction of the pull rod. Since the grip ball is in snap-fit with the limit sleeve, when the pull rod is released, the pull rod will not fall into the cylinder body and cannot be taken out.

[0048] Optionally, a scraper is provided on one side of the entrance and exit, and a discharge piece is provided at the lower end of the pull rod.

[0049] Specifically, after the cylinder body is inserted into the slag, the discharge piece is brought to the lower side of the feed port by the pull rod. The slag enters the cylinder body through the feed port and can fall on the discharge piece. When the pull rod is lifted and taken out from the entrance and exit, the slag can be sampled by the scraper.

[0050] Optionally, the entrance and exit are provided on the top surface of the cylinder body, and the feed hole is provided on the outer circumferential surface of the lower end of the cylinder body.
