Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering technology, specifically to a flexible guide sealing mechanism for a gate hoist. Background Technology

[0002] Gate hoists are essential machines used in water conservancy and mining sectors to control large gates, enabling them to open and close. Winching gate hoists are a type of gate hoist. Traditional winching gate hoists lack a sealing device on the base. During operation, the hoist relies primarily on the wire rope on the drum. The relative movement of the wire rope causes the distance between its two ends to continuously increase or decrease. Since the position of the wire rope cannot be fixed during this constant change, an opening is needed to ensure the wire rope can move freely within its working range. Consequently, dust, insects, and birds can enter the hoist chamber through the base, affecting not only the cleanliness of the interior but also the safety of electrical boxes and other precision instruments inside. This dust intrusion is particularly pronounced in winching gate hoists used in water conservancy and mining. Existing wire rope sealing mechanisms are prone to jamming during parallel movement and can easily cause hard damage to the wire rope during vertical movement. Utility Model Content

[0003] To address the aforementioned problems, this utility model provides a flexible guide and blocking mechanism for a gate hoist, comprising a fixed frame and a flexible blocking mechanism. The flexible blocking mechanism is movably connected to the fixed frame. Through the special flexible blocking mechanism, the blocking part can move flexibly with the wire rope, making the operation of the wire rope smoother and less prone to hard damage.

[0004] The solution provided by this utility model is as follows:

[0005] A flexible guide and blocking mechanism for a gate hoist includes a fixed frame and a flexible blocking mechanism. The fixed frame is generally rectangular, with its long side being transverse and its short side being radial. The flexible blocking mechanism is movably connected to the fixed frame. The flexible blocking mechanism includes a sliding rod, which is movably connected to the fixed frame and can move laterally along the inner side of the fixed frame.

[0006] The inner side of the long side of the fixed frame is provided with a transverse slide rail, and both ends of the slide rod are movably disposed in the transverse slide rail, so that the slide rod can slide laterally along the long side of the fixed frame.

[0007] The sliding rod includes several side sliding rods and several middle sliding rods. Movable protective covers are provided between the side sliding rods and the fixed frame, and movable protective covers are provided between the middle sliding rods. These movable protective covers are used to prevent dust, insects, and birds from entering. One end of the movable protective cover between the side sliding rod and the fixed frame is connected to the short side of the fixed frame, and the other end is connected to the side sliding rod. Both ends of the movable protective covers between the middle sliding rods are respectively connected to two adjacent middle sliding rods.

[0008] There are two central sliding rods and two side sliding rods, and three movable protective covers.

[0009] The movable protective cover is generally a bellows plate, and the two sides of the bellows plate are respectively arranged in the horizontal slide rails on the fixed frame, so that the bellows plate can be opened and closed horizontally.

[0010] A slider is movably provided between the side slide bar and the middle slide bar. A wire rope through hole is provided in the middle of the slider. The wire rope of the hoist passes through the wire rope through hole. The slider can move radially along the side slide bar and the middle slide bar.

[0011] The side slide rod and the middle slide rod are each provided with radial slide rails on opposite sides, and the two ends of the slider are respectively movably disposed in the radial slide rails, so that the slider can slide radially along the slide rod.

[0012] It also includes a sealing cover plate, which is fixedly connected to the slider. The sealing cover plate is used to cover the gap between the side slider and the middle slider caused by the slider, and can move with the slider.

[0013] The sealing cover plate is provided with a funnel-shaped protective tube, the bottom end of which is connected to the through hole of the wire rope for the purpose of protecting the wire rope.

[0014] The slider has two guide wheels on its lower side, which are arranged opposite each other. The space between the two guide wheels cooperates with the through hole of the wire rope to assist in the winding and unwinding of the wire rope, avoid rigid friction, and guide the wire rope to make winding and unwinding smoother.

[0015] The working principle of this utility model is as follows:

[0016] When the gate hoist is working, the wire ropes on both sides move relative to each other as the drum rotates. Their relative positions change laterally as the gate approaches the drum. The sealing mechanism of this invention allows the wire rope through-hole to move laterally through the cooperation of the sliding rod and the lateral slide rail, causing the movable protective cover to follow suit and achieve tight protection. Simultaneously, the wire rope is prone to radial sway during movement. The sealing mechanism of this invention allows the wire rope through-hole to move radially through the cooperation of the slider and the radial slide rail, and then, with the sealing cover plate, seals the gaps between the sliding rods. This ensures that the sealing mechanism can move flexibly regardless of the wire rope's position. Furthermore, the design of the guide wheel and funnel protective tube guides the movement of the wire rope and protects it.

[0017] Compared with the prior art, the advantages of this utility model are:

[0018] 1. A radial movement function has been added to enable flexible movement in multiple directions and provide close protection by following the movement of the wire rope.

[0019] 2. Flexible movement prevents the wire rope from being damaged due to rigid friction with the wire rope through hole caused by multi-directional swaying during movement.

[0020] 3. The guide wheel design guides the movement of the wire rope while avoiding rigid friction, thus increasing the life of the wire rope.

[0021] 4. Detachable design for easy installation and maintenance. Attached Figure Description

Detailed Implementation

[0027] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0028] As shown in the figure, a flexible guide and blocking mechanism for a gate hoist includes a fixed frame 5 and a flexible blocking mechanism. The fixed frame 5 is generally rectangular, with its long side being horizontal and its short side being radial. A transverse slide rail 12 is installed on the inner side of the long side of the fixed frame 5. The two side slide rods 2 and the two middle slide rods 4 are all installed in the transverse slide rail 12 at both ends through a pulley structure, so that the slide rods can slide laterally along the long side of the fixed frame.

[0029] A bellows plate 1 is installed between the two side slide rods 2 and the short sides of the fixed frame 5. One end of the bellows plate 1 is connected to the short side of the fixed frame 5, and the other end is connected to the middle slide rod 4. The bellows plate 1 is also installed in the transverse slide rail 12 through a pulley structure on both sides. A bellows plate 1 is also installed between the two middle slide rods 4. The two ends of the bellows plate 1 are connected to the two middle slide rods 4 respectively, and the two sides are also installed in the transverse slide rail through a pulley structure.

[0030] Radial slide rails 6 are installed on the opposite sides of adjacent side slide rods 2 and middle slide rods 4. Slide blocks 7 are installed on both sides within the corresponding radial slide rails 6, allowing them to slide radially along the radial slide rails 6. A wire rope through hole 8 is provided in the middle of slide block 7 for the hoist wire rope 10 to pass through. Slide block 7 can be constructed using two concave-shaped components for easy installation. A funnel protection tube 11 is installed on the upper side of slide block 7, with its bottom welded or bolted to the slide block 7 and aligned with the wire rope through hole 8. A pair of guide wheels 13 are installed on the lower side of slide block 7, with a certain gap between them, the gap distance not less than the diameter of the wire rope through hole 8, to guide the wire rope 10.

[0031] Both ends of the gap formed between the side slide rod 2 and the middle slide rod 4 are bolted to a connecting plate 3 to connect the side slide rod 2 and the middle slide rod 4. This ensures that the side slide rod 2 and the middle slide rod 4 always slide synchronously and parallelly, preventing the radial slide rails 6 on both sides from becoming non-parallel and affecting the radial sliding of the slider 7. The width of the connecting plate 3 is the same as the width of the slider 7.

[0032] A sealing cover plate 9 is also bolted to the upper side of the slider. The width of the sealing cover plate 9 is the same as that of the slider 7, and its length is slightly longer than the distance between the two connecting plates 3. It is used to seal the space in the gap formed between the slider rods that is not sealed by the slider and the connecting plate. The length must be sufficient to ensure that the sealing cover plate 9 can still seal the remaining gaps as the slider moves radially.

[0033] During installation, the sealing mechanism of this utility model is installed on the base of the winch-type gate hoist, and the two wire ropes 10 are passed through the two wire rope through holes 8 respectively. When the gate hoist is in use, as the wire ropes 10 move, the relative distance changes, driving the slider 7 and slide bar to move laterally through the wire rope through holes 8. The bellows plate 1 follows the lateral movement, providing tight protection. When the wire rope 10 moves radially, the slider 7 can slide radially through the radial slide rail 6, allowing the slider 7 to closely follow the movement of the wire rope, achieving flexible movement and avoiding rigid friction with the wire rope. Simultaneously, when the wire rope moves, the guide wheel 13 at the bottom of the slider provides auxiliary guidance, and the upper funnel protective pipe 11 also protects the wire rope, preventing rigid friction between the wire rope and the wire rope through holes and extending the service life of the wire rope.
