Description

A capstan grinder for electric power engineering

Technical Field

The utility model relates to the technical field of capstan grinders, and more specifically, to a capstan grinder for electric power engineering.

Background Art

The motorized capstan is an essential construction tool for tightening wires and erecting poles when erecting overhead high-voltage transmission lines and laying underground cables. It can smoothly and conveniently erect conductors for lifting, pulling or tightening wires in various complex environments. During the construction and maintenance of transmission lines, it is necessary to lift hardware, porcelain bottles, wire-laying pulleys, and tools, adjust large ropes and pulleys, and extend pulley groups. The capstan needs to be used as a traction tool during the above operations. However, during the construction process, too much wire is often wound on one side of the reel, causing the cable to be entangled to the outside, resulting in a failure to reel in.

The utility model with announcement number CN212893167U discloses a capstan for power engineering. During the operation of the capstan, the cable is wound on the drum for winding. The thickness of the cable wound on the drum increases with the rotation of the rotating shaft. At this time, the operator energizes the telescopic device, the telescopic device starts, the telescopic device drives the support plate to move, the support plate drives the fixed seat to move, the fixed seat drives the drum to move, the movement of the drum drives the cable to move, the cable changes its winding position in the drum, and effectively avoids the cable being wound too much on one side of the drum, resulting in the coil being too thick and causing side slip.

When the above-mentioned capstan is in use, one end of the rotating shaft is connected to the power mechanism, and the other end of the rotating shaft is connected to the bracket arranged on the fixed seat. The wire drum is driven to rotate by the power mechanism. When the power mechanism fails, the wire drum rotates rapidly in the opposite direction under the drive of the gravity of the cable, which poses certain safety hazards.

Utility Model Content

In order to overcome the above-mentioned defects of the prior art, the utility model provides a capstan grinder for electric power engineering, aiming to solve the problems raised in the above-mentioned background technology.

To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a capstan grinding machine for electric power engineering, comprising a mounting frame, a wire drum movably arranged on the mounting frame, a first connecting piece and a second connecting piece movably arranged on both sides of the wire drum, a rotating assembly is provided on one side of the second connecting piece, the rotating assembly comprises a motor, a third rotating shaft, a worm, a fourth rotating shaft and a worm wheel, the motor is fixedly mounted on the inner rear side of the mounting frame, the rear end of the third rotating shaft is fixedly connected to the end of the motor output shaft, and the front end of the third rotating shaft is movably connected to the mounting frame through a bearing, the worm is fixedly sleeved on the third rotating shaft, and the worm wheel is fixedly sleeved on the fourth rotating shaft, one end of the fourth rotating shaft is movably connected to the mounting frame through a bearing, and the other end of the fourth rotating shaft is fixedly connected to the second connecting piece.

Furthermore, a plurality of fixing bolts are disposed on the first connecting plate and the second connecting plate, and the wire drum is fixed to the second connecting plate and the first connecting plate respectively by the plurality of fixing bolts.

It can be seen that in the above technical solution, the fixation between the wire drum and the first connecting piece, and between the wire drum and the second connecting piece is released by a plurality of fixing bolts, and the wire drum is disassembled and replaced, and the wire drum is installed similarly.

Furthermore, two first mesh plates and two second mesh plates are fixedly connected inside the mounting frame, and the two second mesh plates are located between the two first mesh plates.

Furthermore, a second rotating shaft is movably connected to the other side of the interior of the mounting frame via a bearing, and a fan blade is fixedly mounted on one end of the second rotating shaft.

Furthermore, a transmission assembly is disposed on the second rotating shaft, and the transmission assembly includes a first rotating shaft, a first column gear and a second column gear.

Furthermore, one end of the first rotating shaft is movably connected to one side of the interior of the mounting frame via a bearing, and the other end of the first rotating shaft is fixedly connected to the first connecting piece, and the first column gear is fixedly sleeved on the first rotating shaft.

Furthermore, the bottom end of the mounting frame is fixedly connected to a base.

It can be seen that in the above technical solution, by providing a base, it is convenient to support the mounting frame.

Technical effects and advantages of the utility model:

1. The utility model drives the third rotating shaft to rotate through the operation of the motor, thereby driving the worm to rotate. Since the worm is meshed with the worm wheel, the worm can drive the worm wheel to rotate, thereby driving the fourth rotating shaft to rotate, and then driving the second connecting piece to rotate. The second connecting piece can drive the wire drum to rotate, and the cable is wound. Since the worm wheel cannot drive the worm to rotate, the wire drum cannot rotate under the gravity of the cable. The structure is simple and has the function of emergency braking to avoid safety accidents.

2. The utility model can drive the first connecting plate to rotate through the wire drum, thereby driving the first rotating shaft to rotate, and then driving the first column gear to rotate. Since the first column gear is meshed with the second column gear, and the first column gear is a large column gear and the second column gear is a small column gear, the first column gear can drive the second column gear to rotate faster, thereby driving the second rotating shaft to rotate, and then driving the fan blades to rotate. External air enters the mounting frame through the first mesh plate and is discharged through the second mesh plate to dissipate heat to the cable and the motor. The structure is simple and easy to use.
