Description

A portable manual wire collection device

technical field

The invention relates to a portable manual wire collection device, which belongs to the technical field of electric power distribution line maintenance construction.

Background technique

In the process of high-voltage power transmission and distribution, sudden power outages caused by damage to towers will cause huge economic losses. With the rapid development of industrial and agricultural modernization, the intensification of environmental pollution has caused the corrosion of tower foundations, grounding wires, stay wires and rods of transmission lines; at the same time, tower materials, bolts, nuts, tower stay wires, fittings, etc. of line towers are also often stolen. Molecules steal and destroy. Therefore, in order to prevent accidents such as wire being stolen or damaged by other external forces, to ensure that the repair work is completed in a short time, to avoid sudden power failures affecting production due to line damage, and to cause huge economic losses, it is necessary to develop a light and portable temporary pull wire The wire collection device is used for maintenance of the pull wire of the pull tower when the line is running normally (live) or a short-term replacement when the pull wire is damaged, so as to ensure the safe operation of the wire tower. Especially when it is used in the maintenance process of towers in mountainous areas, in the absence of power equipment, the live correction of the tower and the adjustment of the cable are only done manually.

Contents of the invention

In order to solve the above technical problems and overcome the deficiencies in the prior art, the present invention provides a portable manual wire collection device. The present invention adopts the following technical scheme: a portable manual wire collection and collection device, which is characterized in that it includes a frame, and the frame is provided with a guide pulley, a tapered shaft, and a wire collection reel, and one end of the tapered shaft A large gear rotating coaxially is provided, a pinion meshing with the large gear is provided on the side of the frame, and a coaxial handle is provided outside the pinion.

Furthermore, the central plane of the guide pulley is aligned with the central plane of the tapered shaft, so as to avoid the deflection angle when the steel wire rope is wound in, causing the steel wire rope to be easily worn, and the mutual friction between the ropes is not conducive to the twisting of the steel wire rope.

Furthermore, one end of the wire gathering reel is provided with a wire clamping groove for locking the end of the wire rope wound on the wire gathering reel.

Furthermore, the other end of the wire-collecting reel is provided with a ratchet mechanism that rotates coaxially to realize real-time reverse locking of the reel, so as to avoid injury to workers due to excessive load.

Furthermore, the ratchet mechanism includes a ratchet and a pawl arranged on the frame, and the other end of the pawl is provided with a reversing button that rotates coaxially to control whether the ratchet is in a locked or released state, so as to realize winding and unwinding. The two kinds of energy of the line.

Furthermore, the end of the frame is provided with a plurality of ear plates, which are used to install shackles. When the load is large, it is necessary to use steel brazing to fix the whole device on the ground.

The beneficial effects achieved by the present invention: (1) Lightweight and portable, it can be widely used in the maintenance process and handling process of the mountain line; (2) The large gear and the handle of the device can be disassembled, and only two workers are needed in the construction project The work can be completed without additional power equipment, which greatly reduces the labor intensity of workers; (3) The ratchet realizes the real-time reverse locking of the wire collection reel, avoiding the injury of workers due to excessive load and reverse rotation of the mechanism.

detailed description

The present invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

As shown in Fig. 1 is the structure diagram of the present invention, the present invention comprises frame 1, is provided with guide pulley 2, tapered shaft 3, collection reel 8 on frame 1, and one end of tapered shaft 3 is provided with coaxial For the rotating bull gear 4, the side of the frame 1 is provided with a pinion 6 meshing with the bull gear 4, the outside of the pinion 6 is provided with a coaxial handle 5, and the end of the frame 1 is provided with an ear plate 12.

After the wire rope passes through the guide pulley 2, the centering action of the guide pulley 2 adjusts the direction to the direction perpendicular to the cone bottom of the tapered shaft 3, that is, the center plane of the guide pulley 2 is aligned with the center plane of the tapered shaft 3 (such It can reduce the deflection angle of the wire rope when it is wound in, and effectively reduce the wear of the wire rope), and then wind it on the tapered shaft 3 for 3-4 turns to ensure sufficient wrap angle and prevent frictional transmission due to excessive load. skidding.

During the construction process, the worker uses the handle 5 to drive the small gear 6, and drives the large gear 4 through the meshing action of the gears. The transmission ratio of the gears in the embodiment is 3, so although the transmission speed is reduced, it is only one-third of that without gears , but the load capacity is increased by 3 times, and the labor intensity of workers is reduced under the same conditions.

The large gear 4 and the conical shaft 3 rotate coaxially, so that the torque of the handle 5 can be transmitted to the conical shaft 3, and the conical shaft 3 is driven to overcome the frictional moment generated when the wire rope is wound on it, thereby realizing the twisting effect, and the The wire rope is twisted in, so that the driving torque only needs to overcome the frictional moment of the wire rope acting on the tapered shaft 3 to be involved in the wire rope, which greatly reduces the input torque and achieves the purpose of labor saving.

The tapered shaft 3 rolls in the wire rope on one side and rolls it out on the other side. At this time, another worker rotates the wire collection reel 8 in time to wind the unwound wire rope onto the wire collection drum 8, and the end of the wire rope is pulled out by The wire clamp groove 7 installed on the end of the wire collection reel 8 is fixed, and a coaxially rotating ratchet mechanism is installed on the other end of the wire collection reel 8. The ratchet mechanism includes a ratchet 10 and a ratchet arranged on the frame. The claw 9 realizes the function of reverse locking while taking up the thread, avoiding the worker from being injured by the reverse rotation of the handle 5 due to excessive load during the construction process of the worker, and improving the operation safety.

The other end of the ratchet 9 is provided with a reversing button 11 that rotates coaxially. When the tension is excessive, the reversing button 11 can be toggled to release the ratchet 9. The button 11 realizes real-time locking.

In this embodiment, the maximum tractive force is 5 tons. At this time, a shackle needs to be installed on the ear plate 12, and the steel wire rope is passed through the shackle to connect with the steel braze to fix the whole device on the ground.

The present invention can be widely used in mountainous area line maintenance process and handling process, the large gear 4 and the handle 5 can be disassembled, only two workers can complete the work in the construction project, no additional power equipment is needed, after safety inspection and force school Nuclear, a kind of portable manual wire take-up device of the present invention maximum traction can reach 5 tons.

The above is only a preferred embodiment of the present invention, it should be pointed out that for those of ordinary skill in the art, without departing from the technical principle of the present invention, some improvements and modifications can also be made. It should also be regarded as the protection scope of the present invention.
