Description

Technical Field

[0001] The present application relates to a lifting device for a converter auxiliary gun, and in particular to a hanging bracket for the converter auxiliary gun. Background Art

[0002] The converter sub-lance is an important device for measuring temperature, sampling, carbon determination and oxygen determination of the final molten steel during converter production. It provides molten steel composition data for converter production and guides production. Since the sub-lance has a small outer diameter and a long axial length (for example, a certain sub-lance has an outer diameter of 114mm and a length of 22m), it is very easy to deform and bend during the lifting process, making it unusable. Especially in the process of lifting the sub-lance from a horizontal position to a vertical position, the sub-lance head is very easy to deform after being stressed, resulting in water leakage or even breakage, which seriously restricts the service life of the sub-lance. Under this background, a special hanger to prevent the deformation of the sub-lance is invented.

[0003] Patent CN106348152A discloses a hoisting device and hoisting method for safely hoisting the auxiliary gun of a furnace. The hoisting device includes a hoisting rod, a hoisting support steel plate fixed to the hoisting rod, a semicircular groove on the front of the hoisting support steel plate, a gun body clamp is a semicircular ring, the gun body clamp and the semicircular groove of the hoisting support form a circular ring, the inner diameter of the circular ring matches the outer diameter of the auxiliary gun, the lower part of the hoisting rod is welded to the tail sleeve, the inner diameter of the tail sleeve matches the outer diameter of the auxiliary gun, and the upper and lower ends of the hoisting rod have a top hoisting point and a tail hoisting point respectively. However, this hoisting device is hoisted at the top and bottom at the same time, which makes it not flexible enough, especially when it is necessary to change the horizontal / vertical state, and complex equipment and operations are required.

[0038] The embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments.

[0039] It should be noted that when a component is considered to be "connected" to another component, it may be directly connected to the other component or there may be a central component at the same time. When a component is considered to be "located on" another component, it may be directly located on the other component or there may be a central component at the same time. The terms "top", "bottom", "upper", "lower", "left", "right", "front", "back", and similar expressions used herein are for illustrative purposes only.

[0040] Some embodiments of the present application are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0041] See also Figure 1-4 The utility model provides a hanger for a converter auxiliary gun, comprising:

[0042] Base;

[0043] A lifting connector is rotatably disposed at one end of the base and is used to connect a lifting device. The lifting connector includes:

[0044] A fixing seat, fixed to one end of the base;

[0045] The rotating seat comprises a first part and a second part connected to each other, wherein the connection between the first part and the second part is pivotally connected to the fixed seat, the first part is provided with a suspension rod to connect the lifting equipment, and when the base is placed on the bottom surface, the first part is perpendicular to the base, and the second part is parallel to the base; when the base is vertically suspended, the first part is parallel to the base, and the second part is perpendicular to the base;

[0046] A plurality of supports, provided on the base, for supporting the auxiliary guns;

[0047] A protective tube is arranged at the other end of the base and is used for being sleeved on the gun head of the auxiliary gun.

[0048] See also Figure 5 , Figure 5 The portion indicated by the dotted line is a schematic diagram after the protection plate is opened.

[0049] The support comprises:

[0050] A main body, arranged on the base, the main body is provided with a receiving slot for receiving the auxiliary gun;

[0051] A protection plate is rotatably disposed on the main body to lock or unlock the auxiliary gun, and the protection plate is provided with a mounting groove to accommodate a portion of the auxiliary gun protruding from the receiving groove;

[0052] A fixing member (not shown) is used to lock the protection plate to the main body.

[0053] See also Figure 6 , the hanger also includes:

[0054] The support seat is arranged on the base and is used to support the gun tail of the auxiliary gun. The support seat is provided with a U-shaped groove, and a guide part is arranged outside the U-shaped groove.

[0055] See also Figure 2 , the protection tube comprises:

[0056] A connecting member, fixed to the base;

[0057] The conical sleeve is fixed to the connecting piece and is used for installing and protecting the auxiliary gun head.

[0058] The base is a round tube.

[0059] See also Figure 7 and Figure 8 , the hanger also includes:

[0060] Support parts, including:

[0061] A first support plate, fixed to the base, for supporting the bottom surface;

[0062] The second support plate is fixed to the first support plate and is provided with a slot for mounting the auxiliary gun.

[0063] Furthermore, the second support plate is provided with a card plate, and the card plate is used to fix the auxiliary gun on the second support plate. Furthermore, the base is provided with rollers. When the hoisting hanger is converted from a horizontal position to a vertical position, the rollers assist in supporting and facilitate the movement of the base. No other auxiliary trolleys, tracks and other equipment are required.

[0064] Specifically, a seamless steel pipe with a length of 23 meters, a diameter of 273mm, and a wall thickness of 10mm is used as the base. The fixed seat is welded to the top of the base. The rotating seat is connected to the fixed seat by a pin. There is a 180° rotation range between the rotating seat and the fixed seat to meet the angle change requirements of the hanger from the horizontal position to the vertical position. A set of support parts is welded on both sides of the base every 4 meters to ensure that the steel pipe cannot roll and can be placed horizontally and stably. A support is welded on the top of the base every 4 meters. The support is a 200*400 V-shaped rib plate. A hinged switchable protection plate is installed on each V-shaped rib plate, and a funnel-shaped protection tube is made at the tail to protect the important position of the auxiliary gun head. When the auxiliary gun is placed horizontally on the hanger, the protection plate is closed to prevent the auxiliary gun from sliding out of the V-shaped rib plate during the lifting process. After the overall hoist is vertically hoisted to the spare position, the protection plate is opened and the auxiliary gun can be replaced normally. Since the hanger is slightly deformed by force during the lifting process, the auxiliary gun placed on the hanger is basically not deformed. The problem of the inconvenience of hoisting the auxiliary gun due to its thin, long and soft structure is solved by making the hanger thick, long and hard.

[0065] In addition, those skilled in the art should recognize that the above embodiments are only used to illustrate the present application, and are not intended to limit the present application. As long as they are within the spirit and scope of the present application, appropriate changes and modifications to the above embodiments are within the scope of the present application.
