Description

Technical Field

[0001] This utility model relates to the field of sealing and protection technology, specifically a telescopic gate hoist sealing device. Background Technology

[0002] In water conservancy projects, several control gates and inverted siphon gates are set up along the entire canal. Currently, the raising and lowering of the gates are generally accomplished by rotating the drum to drive the wire rope to wind up and down. The drum has reverse threads on both sides, and the two ends of the wire rope are wound in the reverse threads. The middle of the wire rope passes through the lifting hole and downward through the lifting pulley block connected to the gate. When the drum rotates and drives the gate to rise, the vertical wire rope moves in opposite directions and is neatly arranged in the thread groove of the drum. The distance between the two ends of the wire rope continuously shortens. When the drum rotates and drives the gate to fall, the wire rope moves relative to each other, and the distance between the two ends of the wire rope continuously increases. Since the position of the wire rope is constantly changing, it is necessary to reserve an opening to ensure that the wire rope can run smoothly within the working range. However, the current movement space reserved for the wire rope is directly exposed to the external environment, resulting in poor sealing inside the winch. External debris and garbage can enter the winch under the influence of airflow, causing pollution. Furthermore, small animals such as birds can enter the winch and damage the equipment. Therefore, this utility model provides a telescopic hoist sealing device to meet people's needs. Utility Model Content

The width of the side telescopic protective covers 404, nylon blocks 405 and central telescopic protective cover 407 is the same as the width of the guide frame 403. The bottom ends of the side telescopic protective covers 404 and central telescopic protective cover 407 are tightly attached to the top of the guide frame 403. The bottom ends of the guide frame 403 are symmetrically connected to mounting side plates 408. Mounting bolts 409 are symmetrically mounted on both ends of the mounting side plates 408. Both mounting side plates 408 are tightly attached to the top of the transparent acrylic sealing plate 401. The mounting bolts 409 extend through the mounting side plates 408 and the transparent acrylic sealing plate 401. The mounting side plates 408 and the winch 1 are fixedly connected by the mounting bolts 409. The top of the winch 1 is sealed by the transparent acrylic sealing plate 401. Simultaneously, the side telescopic protective cover 404, nylon block 405, and... The central telescopic protective cover 407 provides sufficient lateral swing space for the steel wire rope used in the hoist. The nylon block 405 increases the contact with the steel wire rope, so the swing of the steel wire rope can be controlled. The side telescopic protective covers 404 and the central telescopic protective cover 407 are used to expand or retract, which fully shields the moving position of the steel wire rope and plays a sealing and protective role. This prevents the moving area of ​​the steel wire rope from being directly exposed to the external environment, which could cause small animals such as birds to crawl in and damage the electrical components, thus improving the overall safety of the equipment. A positioning guide mechanism 5 is provided at the top of the guide frame 403; The positioning and guiding mechanism 5 includes a guide groove 501, a support roller 502, a positioning cylinder 503, an arc-shaped support block 504, an L-shaped positioning block 505, a mounting screw hole 506, a stabilizing strip 507, and a locking bolt 508. The top two sides of the guide frame 403 are symmetrically provided with guide grooves 501. Support rollers 502 are symmetrically installed inside the two guide grooves 501. A positioning cylinder 503 is installed in the middle of the support rollers 502. Arc-shaped support blocks 504 are connected to the bottom of both ends of the nylon block 405. The length of the positioning cylinder 503 is the same as the width of the guide groove 501. The arc-shaped support blocks 504 are in close contact with the top surface of the support rollers 502. L-shaped positioning blocks 505 are installed at the four corners of the top of the guide frame 403. Mounting screw holes 506 are provided on one side of the L-shaped positioning blocks 505 at the top of the guide frame 403. Stabilizing strips 507 are symmetrically fitted to both sides of the top of the guide frame 403. Locking bolts 508 are symmetrically installed at both ends of the stabilizing strips 507. The bottom end of the stabilizing strip 507 is tightly attached to the top of the side telescopic protective cover 404, the nylon block 405, and the central telescopic protective cover 407. The two ends of the stabilizing strip 507 are respectively tightly attached to two L-shaped positioning blocks. 505, the bottom of the locking bolt 508 extends into the interior of the mounting screw hole 506. The guide groove 501 and the support roller 502 cooperate with each other to guide and stabilize the movement of the nylon block 405, making the movement of the nylon block 405 more stable. The arc-shaped support block 504 fits perfectly with the support roller 502, making the connection between the two ends of the nylon block 405 and the support roller 502 more convenient, quick and stable. The positioning cylinder 503 limits the support roller 502 and prevents the support roller 502 from disengaging from the guide groove 501. The stabilizing strip 507 is used to limit and press the side telescopic protective cover 404, nylon block 405 and central telescopic protective cover 407, so that the expansion and contraction of the side telescopic protective cover 404 and central telescopic protective cover 407 are more stable, and the upward displacement and shaking of the side telescopic protective cover 404, nylon block 405 and central telescopic protective cover 407 during movement will cause poor sealing.

[0017] The working principle and usage process of this utility model are as follows: First, two steel wire ropes are evenly wound on the surface of the winding drum 3 inside the winch 1. Both steel wire ropes pass upward through the through hole 406 in the middle of the nylon block 405 and are connected to the gate of the hoist. The drive motor 2 drives the winding drum 3 to rotate, and the raising and lowering of the gate is controlled by winding and unwinding the steel wire ropes. Affected by the raising and lowering of the gate, the steel wire ropes will swing left and right. When the gate rises, the two steel wire ropes move towards each other, thereby pushing the two nylon blocks 405 to gradually move closer to each other, with the middle telescopic protection... The cover 407 is compressed, while the two side telescopic protective covers 404 are stretched. When the gate descends, the two steel wire ropes move relative to each other, pushing the two nylon blocks 405 away from each other. As a result, the central telescopic protective cover 407 is stretched, and the two side telescopic protective covers 404 are compressed. The side telescopic protective covers 404 and the central telescopic protective cover 407 are always in close contact with the top of the guide frame 403, covering the rectangular movable groove 402, so that the top of the transparent acrylic sealing plate 401 remains closed, which plays a role in sealing and protecting the winch 1. The arc-shaped support blocks 504 installed at both ends of the nylon block 405 are both engaged with the surface of the support rollers 502. The support rollers 502 are limited inside the guide groove 501 by the influence of the positioning cylinder 503. The support rollers 502 play a role in supporting and stabilizing the nylon block 405. When the nylon block 405 moves, the support rollers 502 roll inside the guide groove 501, which improves the movement stability of the nylon block 405. At the same time, the stabilizing strip 507 is fixed to the top of the guide frame 403 by the locking bolts 508. It presses tightly against the top of the side telescopic protective cover 404, the nylon block 405 and the middle telescopic protective cover 407, making the opening and closing of the side telescopic protective cover 404 and the middle telescopic protective cover 407 more stable, and preventing the side telescopic protective cover 404 and the middle telescopic protective cover 407 from bulging upward and shifting when opening or closing, which would affect the overall sealing performance.

[0018] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
