Description

Technical Field

[0001] The utility model relates to the technical field of iron-making blast furnaces, in particular to an auxiliary installation tool for an anti-dropping latch of a blast furnace material distribution chute. Background Art

[0002] The chute is installed in the blast furnace and is the last diversion channel for the charge to enter the blast furnace during the blast furnace charging process. To prevent falling off, as disclosed in the patent document of Chinese patent application No. 202221782013.5, a latch groove is usually provided on the back of the chute, and a latch is inserted into the latch groove. The latch is fixed to prevent the chute from falling off during operation. When replacing and installing the chute, affected by the working environment, the operator cannot enter the blast furnace, and can only be outside the blast furnace. With the help of a latch auxiliary installation device, the latch is sent into the blast furnace through the blast furnace manhole and inserted into the latch groove on the back of the chute. The latch auxiliary installation device, as disclosed in the patent document of Chinese patent application No. 202320665903.6, generally includes a long rod, and a latch hook is provided at the end of the long rod. When the latch is inserted into the latch groove on the back of the chute, the latch hook is hung on the latch hook, and the operator holds the long rod for remote operation. The existing bolt auxiliary installation device has a heavy bolt. The operation of inserting the bolt into the narrow bolt slot from a distance is not only time-consuming and laborious, but also difficult to install. In addition, during the operation, the bolt simply hooked on the bolt hook is easy to fall off, and the stability and reliability of the operation are low. Utility Model Content

[0003] The utility model aims to provide an auxiliary installation tool for preventing the falling-off of a bolt of a blast furnace material distribution chute.

[0004] The technical solution to achieve the purpose of the utility model is: an auxiliary installation tool for the anti-dropping plug of the blast furnace distribution chute, which is used for the auxiliary installation of the plug, and the plug has more than one through hole;

[0005] The auxiliary installation tool for the anti-dropping pin of the blast furnace charging chute includes a long rod, a pin hook is installed on the side wall of the first end of the long rod, the pin hook passes through the through hole of the pin, the pin is spot welded to the long rod, a rope passes through the through hole and is folded in half, and a ruler is fixedly installed on the second end of the long rod, and the ruler is parallel to the pin hook.

[0006] Further, the latch hook is vertically mounted on the side wall of the long pole. The latch hook can be installed on the side wall of the long pole at an angle or vertically. Compared with the inclined installation, the vertical installation is more convenient for operation.

[0007] Furthermore, the latch hook is a bolt installed on the side wall of the long rod. The bolt can be easily installed, and the bolt cap of the bolt can naturally constitute the limiting structure of the latch hook, making the formation of the latch hook more convenient.

[0008] Furthermore, the through hole through which the latch hook passes is located in the middle of the latch. Under this arrangement, the position of the through hole through which the latch hook passes is closer to the center of gravity of the latch, and after the latch is hooked on the latch hook, the swing tendency is small and the stability is better.

[0009] Furthermore, the number of the through holes is several, and the latch hook and the rope pass through two different through holes respectively. The latch hook and the rope do not affect each other, which is more convenient for operation.

[0010] Furthermore, the number of the through holes is three, the latch hook passes through the middle through hole, and the rope passes through the upper through hole. The latch hook passes through the middle through hole, which is closer to the center of gravity of the latch; the rope passes through the upper through hole, and when the rope is pulled out from the upper through hole, the field of vision can be better, which is more conducive to convenient operation.

[0011] Furthermore, the ruler and the long pole are in a cross shape. The ruler is long, and when operating on both sides of the long pole, operators on both sides can determine the angle of the latch hooked on the latch hook according to the angle of the ruler, and the ruler can also be used as a handle for easy grasping to operate the long pole.

[0012] Furthermore, the long rod is supported on a cross bar, and the cross bar is transversely mounted on the manhole of the blast furnace. After the cross bar is transversely mounted on the manhole of the blast furnace, during operation, the long rod is supported on a cross bar, and the operator can save more effort.

[0013] The utility model provides an auxiliary installation tool for preventing the latch from falling off of a blast furnace distribution chute. By spot welding the latch and the long rod, the latch cannot shake relative to the long rod under the fixing effect of the spot welding. Thus, on the one hand, the height and angle of the latch can be adjusted more accurately by holding the long rod, thereby making it more convenient and quicker to insert the latch into the latch groove on the back side of the chute. On the other hand, the latch that cannot shake relative to the long rod can effectively prevent itself from falling off from the latch hook, thereby improving the reliability of operation.

[0014] The utility model auxiliary installation tool for preventing the bolt from falling off the blast furnace distribution chute also uses the setting of the rope so that once the bolt falls off from the bolt hook, the rope passing through the through hole and connected to the bolt can also pull up the bolt that has fallen off, ensuring that the bolt will not completely lose control and fall into the blast furnace. The bolt is fixed to the long rod by spot welding to ensure the firmness of the bolt after it is installed on the bolt hook, so that the bolt is not easy to fall off from the bolt hook; the rope passing through the through hole ensures that the bolt will not completely lose control and fall into the blast furnace after the bolt falls off from the bolt hook. For all situations that may occur during use, the utility model auxiliary installation tool for preventing the bolt from falling off the blast furnace distribution chute has taken preventive measures, which can ultimately greatly ensure the reliability and safety of operation.

[0015] In addition, the utility model of the auxiliary installation tool for the anti-dropping bolt of the blast furnace distribution chute is also provided with the ruler, which is located at the second end of the long rod and parallel to the bolt hook. The ruler parallel to the bolt hook plays a reference and pointing role. According to the angle of the ruler, the angle of the bolt hook can be determined, and then the angle of the bolt hooked on the bolt hook can be confirmed, so that the bolt can be quickly aligned with the bolt slot on the back of the chute, and the insertion operation of the bolt is more convenient. At the same time, the ruler can also be used as a handle to facilitate hand grip and force application. BRIEF DESCRIPTION OF THE DRAWINGS
