Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary tools for crane equipment maintenance, specifically to a quick disassembly and assembly device for a casting crane plate hook pin shaft. Background Technology

[0002] In smelting enterprises, gantry hooks are crucial equipment in casting cranes. During steel smelting, they are indispensable for hoisting high-temperature liquids, transferring empty ladles, and handling residual slag and steel. During operation, sliding friction occurs between the hook and trunnion, leading to wear and eventual scrapping. Prolonged exposure to high temperatures can cause thermal cracks, and accidents can result in hook separation and torsional deformation, rendering the hook unusable. Therefore, to ensure production safety, gantry hooks must be replaced promptly. However, hook replacement must be done on-site. The limited space and auxiliary equipment on-site greatly complicate the replacement process, especially the installation of the hook pin. The hook and fork shaft holes must be perfectly aligned before the pin can be inserted. The large size and weight of the pin and hook make alignment difficult, requiring repeated adjustments, significantly extending replacement time, disrupting production rhythm, increasing labor intensity, and posing a serious safety hazard.

[0003] Therefore, there is an urgent need to design a quick disassembly and assembly device for cast hanging plate hook pins to solve the problems of long replacement time, low work efficiency, high labor intensity and safety hazards of existing technologies. Utility Model Content

[0004] In view of the problems existing in the prior art, the purpose of this utility model is to provide a quick disassembly and assembly device for casting hanging plate hook pin shaft.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a quick disassembly and assembly device for a cast hanging plate hook pin shaft, including a disassembly head, a limiting block and a connecting head. The disassembly head is installed at the end of the limiting block, the limiting block is provided with a tightening hole, and the other end of the limiting block is provided with a connecting head.

[0006] Specifically, the disassembly head is located at one end of the limiting block, the overall size of the disassembly head is smaller than that of the limiting block, and the disassembly head is welded together with the limiting block.

[0007] Specifically, the limiting block is a trapezoidal steel block, which is placed horizontally so that the height of its left end is smaller than that of its right end, and a tightening hole is provided on the left side of the limiting block.

[0008] Specifically, the tightening hole consists of two through holes, one horizontal and one vertical, which are intersecting on the left side of the limiting block.

[0009] Specifically, the connector is welded to the right end of the limiting block. The connector has a "convex" shaped structure and a threaded post.

[0010] Specifically, the threaded post is a bolt with external threads, and the threaded post is welded to the connector as a whole.

[0011] This utility model has the following beneficial effects:

[0012] The quick-release device for casting hanging plate hook pins designed in this utility model is convenient to connect with the pins, can be quickly connected and disconnected, and has good centering stability; it can prevent unnecessary damage to the pins when removing them, and can provide a strong alignment guide when installing the plate hook pins, ensuring that the pins are quickly assembled into place, greatly reducing maintenance time and labor intensity.

[0016] The technical solutions of the present utility model will be described in further detail below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0017] Example 1:

[0018] like Figures 1-2 As shown, a quick disassembly and assembly device for a casting hanging plate hook pin includes a disassembly head 1, a limiting block 2, and a connecting head 3. The disassembly head 1 is installed at the end of the limiting block 2, the limiting block 2 is provided with a tightening hole 2.1, and the other end of the limiting block 2 is provided with a connecting head 3.

[0019] When using it, first, use a steel rod to alternately insert into the tightening hole 2.1 and rotate it so that the threaded post 3.1 on the connector 3 is threaded together with the central hole at the end of the plate hook pin 4. Install this device with the plate hook pin 4 as a whole to ensure the coaxiality of the connector 3 and the plate hook pin 4. When it needs to be removed, apply external force to the disassembly head 1 to remove the plate hook pin 4. The disassembly head 1 can prevent external force from damaging the plate hook pin 4. When it needs to be installed, after basically aligning the shaft hole of the plate hook pin 4 with the hanging fork hole, insert the limiting block 2 into the shaft hole and hanging fork hole of the plate hook pin 4 for limiting, and then use external force to push so that the plate hook pin 4 can be smoothly installed in place.
