Description

Technical Field

[0001] The utility model relates to the technical field of hoisting equipment tools, in particular to a disassembly tool for an electric hoist. Background Art

[0002] Generally, the motor or reducer on an electric hoist is installed on the I-beam of a single-girder overhead crane. When the motor or reducer on the electric hoist needs to be replaced / repaired regularly, equipment such as a hook chain block or a winch is required to lift the motor or reducer. However, since the distance between the motor or reducer and the I-beam is too small (only 20 cm), the space on the I-beam is not enough to hang a hook chain block or a winch (the self-sizes of the chain block or winch are larger than the space on the I-beam). The existing disassembly and assembly tools can be installed on the I-beam, and then the hook chain block or winch is installed on the disassembly and assembly tool. Finally, the hook chain block or winch is installed on the I-beam. However, the disassembly and assembly of the existing disassembly and assembly tool itself and the I-beam are relatively cumbersome, and the disassembly and assembly time is long, which is not conducive to the rapid repair of the motor or reducer on the electric hoist. Therefore, there is an urgent need for a disassembly tool for an electric hoist to solve the above problems. Content of the Utility Model

[0003] In order to solve the technical problem that the disassembly and assembly of the existing disassembly and assembly tool itself and the I-beam are relatively cumbersome and the disassembly and assembly time is long, the utility model provides a disassembly tool for an electric hoist, which has a simple structure and can be quickly fixed on the I-beam of a single-girder overhead crane, and can meet the disassembly, assembly, repair and replacement of the electric hoist.

[0004] The utility model provides a disassembly tool for an electric hoist, which includes a fixed seat and a self-locking component. The fixed seat is detachably arranged on the I-beam of a single-girder overhead crane through the self-locking component. The self-locking component includes two locking cylinders and a self-locking rod. The two locking cylinders are both movably arranged on the fixed seat and are arranged oppositely. The telescopic rods of the two locking cylinders are respectively fixedly connected with the two self-locking rods and can drive them to slide left and right. The fixed seat is placed on the I-beam, and the ends of the two self-locking rods are both stuck on the I-beam. A hand winch or a chain block is hung on the fixed seat outside the I-beam. A hoisting chain is rotatably arranged on the hand winch or the chain block, and one end of the hoisting chain is fixedly connected with the electric hoist. The fixed seat is placed on the I-beam of the single-girder overhead crane. The two locking cylinders adjust their positions according to the height of the I-beam. The two locking cylinders are started to drive the two self-locking rods to slide relatively. The ends of the two self-locking rods are simultaneously stuck on the I-beam, so that the whole disassembly tool is quickly fixed on the I-beam of the single-girder overhead crane.

[0005] Furthermore, the fixed seat includes a seat body, and two first fixing plates and a second fixing plate arranged on the seat body. The two first fixing plates and the second fixing plate are perpendicular to the seat body; the two first fixing plates are fixedly connected to the top of the side wall of the I-beam, the seat body is located above the I-beam, the two second fixing plates are located outside the I-beam, the two locking cylinders are respectively movably arranged on the two second fixing plates, and the ends of the two self-locking rods are stuck at the bottom of the side wall of the I-beam. The two first fixing plates are fixed on the I-beam, and the locking cylinders drive the ends of the self-locking rods to be stuck on the side wall of the I-beam, so that the whole disassembly tool is quickly fixed on the I-beam.

[0006] Furthermore, flanges are arranged at the edges of the two first fixing plates, and the flanges on each first fixing plate are stuck at the top of the side wall of the I-beam. The two first fixing plates are clamped onto the side wall of the I-beam through the flanges thereon, so that the whole disassembly tool is further stabilized on the I-beam.

[0007] Furthermore, self-locking hooks are arranged at the ends of the two self-locking rods, and the two self-locking hooks are stuck at the bottom of the side wall of the I-beam. By setting the self-locking hooks and making the self-locking hooks stuck on the side wall of the I-beam, the whole disassembly tool is further stabilized on the I-beam.

[0008] Furthermore, linear modules are arranged on the two second fixing plates and the two linear modules are arranged oppositely. The sliders on the two linear modules are respectively fixedly connected to the two locking cylinders and can drive them to slide up and down. The two locking cylinders adjust their positions according to the height of the I-beam, so that when the locking cylinders are started and can drive the two self-locking rods to slide relatively, the ends of the two self-locking rods can be stuck on the I-beam.

[0009] Furthermore, a number of reinforcing ribs are arranged between the two first fixing plates and the seat body and between the two second fixing plates and the seat body. The number of reinforcing ribs increases the overall strength of the disassembly tool and improves its safety during use.

[0010] Furthermore, through holes are arranged on the seat body, hooks are arranged on both the hand winch or the chain block, and the hand winch or the chain block is hung on the through holes of the seat body through the hooks.

[0011] Furthermore, a support plate is arranged on the seat body and the support plate is perpendicular to the seat body. The support plate is located inside the I-beam. A support hole is arranged on the support plate. A fixed shaft is arranged between the two first fixing plates. The fixed shaft is located inside the I-beam and on the side of the support plate. One end of the lifting chain passes through the support hole, bypasses the fixed shaft and is fixedly connected to the electric hoist.

[0012] Compared with the prior art, the utility model has the following technical effects:

[0013] The fixing base is placed on the I-beam of the single-girder overhead crane. The two locking cylinders adjust their positions according to the height of the I-beam. When the two locking cylinders are activated, they drive the two self-locking rods to slide relative to each other. The ends of the two self-locking rods are simultaneously clamped on the I-beam, thereby quickly fixing the entire disassembly tool on the I-beam of the single-girder overhead crane. When in use, the disassembly tool is fixed on the I-beam of the single-girder overhead crane. The hanging hook of the hand winch or the chain block is fixed on the disassembly tool, and the hand winch or the chain block is also fixedly connected to the electric hoist. The operator manually operates the hand winch or the chain block, thereby driving the electric hoist to lift and lower, so as to meet the disassembly, installation, maintenance and replacement of the electric hoist.
