Description

Technical Field

[0001] This utility model belongs to the field of hydraulic metal machinery technology, and relates to rainproof covers, especially a retractable integrated screw-type gate hoist rainproof cover. Background Technology

[0002] In hydraulic engineering, screw-type gate hoists are widely used in maintenance gates and various culvert gates. However, due to limitations, these hoists are often installed outdoors in unobstructed environments. To protect the motors and wiring of these hoists from rain and snow, stainless steel covers are essential. The screw drives the gate's rise and fall through its helical rotation. As the gate rises, the screw extends upwards simultaneously. To ensure that the chimney-shaped cylinder on the cover completely covers the screw's rising height, the cylinder is typically several meters high. This not only affects the cover's aesthetics but also makes it prone to bending and deformation in strong winds and heavy snow, affecting the screw's normal lifting and lowering. This technology addresses the problem of excessive cylinder height by designing an automatically retractable cylinder and integrating the control system within the cover, creating a retractable, integrated rainproof cover for the screw-type gate hoist. Utility Model Content

[0003] The purpose of this utility model is to address the aforementioned problems in existing technologies by proposing a retractable integrated screw-type gate hoist rainproof cover. The technical problem this utility model aims to solve is that straight cylinders can be made several meters high, which not only affects the aesthetics of the cover but also makes it prone to bending and deformation in strong winds and heavy snow, affecting the normal lifting and lowering of the screw.

[0004] The objective of this utility model can be achieved through the following technical solutions:

[0005] A retractable integrated screw-type gate hoist rainproof cover includes a frame, a protective shell fitted on the top of the frame, a gate slidably connected inside the frame, a screw fixedly connected to the top of the gate, the screw slidably connected to the top of the gate, a lifting mechanism for raising and lowering the gate provided on the top of the gate near the screw, a base fixedly connected to the top of the frame near the screw, a threaded groove opened on the top of the base, a bolt cylinder rotatably connected inside the threaded groove, a connecting plate fixedly connected to the top of the bolt cylinder, a sleeve fixedly connected to the top of the connecting plate, two symmetrically opened storage slots on the top of the connecting plate, each storage slot having a constraint mechanism for constraining the sleeve, a protective cylinder provided on the top of the sleeve, a connecting mechanism for connecting the sleeve inside the protective cylinder, and the protective cylinder and the screw being configured to cooperate with each other.

[0006] The working principle of this utility model is as follows: A sleeve is installed on the side of the frame near the screw, and a third extension cylinder, a second extension cylinder, a first extension cylinder, and a protective cylinder are also fitted on the surface of the sleeve. The third extension cylinder, the second extension cylinder, the first extension cylinder, and the protective cylinder are all connected by buckles and slots. As the screw continues to move upward, it will come into contact with the protective cylinder. After it comes into contact with the protective cylinder, it will also drive the protective cylinder to move upward. Because the buckle is smaller than the slot, when the protective cylinder moves upward to a certain height, the slot will limit the buckle, so that the first extension cylinder inside the protective cylinder will also move upward. Since the protective cylinder, the first extension cylinder, the second extension cylinder, and the third extension cylinder are all set by buckles and slots, as the screw continues to move upward, the protective cylinder, the first extension cylinder, the second extension cylinder, and the third extension cylinder will all move upward in sequence, thereby achieving the purpose of protecting the screw.

[0007] The lifting mechanism includes a first synchronous pulley, which is rotatably connected to the top of the gate. A screw is slidably connected to the top of the first synchronous pulley. A screw nut is provided inside the first synchronous pulley near the screw, and the screw nut and screw are mutually engaged. A rotating shaft is rotatably connected to one side of the gate. A second synchronous pulley is fixedly sleeved on the surface of the rotating shaft near the first synchronous pulley. The surfaces of the second and first synchronous pulleys are covered with the same synchronous belt. A worm gear is fixedly sleeved at the bottom of the rotating shaft. A worm is fitted on the surface of the worm gear. The worm is rotatably connected to one side of the gate. A turntable is fixedly connected to the end of the worm away from the gate.

[0008] With the above structure and the synchronous pulley, the screw can drive the valve to rise and fall.

[0009] The constraint mechanism includes a locking post, which is slidably connected to the inside of the storage slot. The top of the base near the locking post has a locking groove, and the locking post is slidably connected to the inside of the locking groove. A limiting plate is fixedly sleeved on the surface of the locking post near the storage slot. A tension spring is sleeved on the surface of the locking post, with the bottom end of the tension spring fixedly connected to the inner surface of the storage slot and the top end of the tension spring fixedly connected to the bottom of the limiting plate.

[0010] The above structure can constrain the sleeve to prevent it from loosening during use.

[0011] The connecting mechanism includes a third extension cylinder, which is slidably connected to the surface of the sleeve. Multiple limiting posts are slidably connected to the top of the third extension cylinder, and each of the limiting posts is fixedly connected to the top of a connecting plate. A limiting plate is fixedly connected to the top of each of the limiting posts, and a spring is sleeved on the surface of each of the limiting posts. Multiple third slots are formed on the surface of the third extension cylinder away from the sleeve, and these slots are evenly spaced in a ring. A third buckle is slidably connected inside each of the third slots. The same second extension cylinder is fixedly connected to the surface of each of the third buckles away from the third extension cylinder. Second slots are formed on the surface of each of the second extension cylinders near the third slots, and second buckles are slidably connected inside each of the second slots. The same first extension cylinder is fixedly connected to the surface of each of the second buckles away from the second extension cylinder, and a first slot is formed on the surface of the first extension cylinder near the second slots. First buckles are slidably connected inside each of the first slots, and the first buckles are sleeved inside a protective cylinder. A limiting cylinder is fixedly connected to the bottom of the protective cylinder, and a screw is slidably connected inside the limiting cylinder.

[0012] The above structure ensures that the third extension tube, second extension tube, first extension tube, and protective tube can operate normally.

[0013] Compared with existing technologies, the retractable integrated screw-type gate hoist rainproof cover of this utility model has the following advantages:

[0014] 1. This utility model, by employing a technical solution of overlapping the third extension cylinder, second extension cylinder, first extension cylinder, and protective cylinder, avoids bending and deformation. This effectively solves the problem of straight cylinders reaching several meters in height, which not only affects the aesthetics of the protective cover but also easily leads to bending and deformation in strong winds and heavy snow, affecting the normal lifting and lowering of the screw. A sleeve is installed on the side of the frame near the screw, and the third extension cylinder, second extension cylinder, first extension cylinder, and protective cylinder are fitted onto the surface of the sleeve. Furthermore, the third extension cylinder, second extension cylinder, first extension cylinder, and protective cylinder are all connected by snaps and grooves. As the screw continues to move upward, it comes into contact with the protective cylinder. Upon contact, it also causes the protective cylinder to move upward. Because the latch is smaller than the slot, when the protective cylinder moves to a certain height, the slot will limit the latch, causing the first extension cylinder inside the protective cylinder to move upward as well. Since the protective cylinder, the first extension cylinder, the second extension cylinder, and the third extension cylinder are all connected by latches and slots, as the screw continues to move upward, the protective cylinder, the first extension cylinder, the second extension cylinder, and the third extension cylinder will all move upward in sequence, thus achieving the purpose of protecting the screw.

[0027] The working principle of this utility model is as follows: When the gate 2 needs to be adjusted, the turntable 209 on one side of the frame 1 can be rotated. A worm gear 208 is installed on one side of the turntable 209, and the worm gear 208 cooperates with the worm wheel 207 on the surface of the rotating shaft 204. Thus, when the turntable 209 rotates, the rotating shaft 204 will rotate synchronously. A second synchronous wheel 205 is installed on the top of the rotating shaft 204, and the second synchronous wheel 205 cooperates with the first synchronous wheel 202 through the synchronous belt 206, so that when the first synchronous wheel 202 also rotates synchronously, a screw nut 203 is provided inside the first synchronous wheel 202, and the screw nut 203 cooperates with the screw 201 on the top of the gate 2.

As the screw 201 continues to move upward, it will come into contact with the protective cylinder 4. After contacting the protective cylinder 4, it will also drive the protective cylinder 4 to move upward. Because the snap-fit ​​is smaller than the slot, when the protective cylinder 4 moves upward to a certain height, the slot will limit the snap-fit, so that the first extension cylinder 403 inside the protective cylinder 4 will also move upward. Since the protective cylinder 4, the first extension cylinder 403, the second extension cylinder 406, and the third extension cylinder 409 are all set by snap-fits and slots, as the screw 201 continues to move upward, the protective cylinder 4, the first extension cylinder 403, the second extension cylinder 406, and the third extension cylinder 409 will all move upward in sequence, thereby achieving the purpose of protecting the screw 201.

[0028] In summary, the core beneficial effect of this utility model is that a sleeve is installed on the side of the frame near the screw, and a third extension cylinder, a second extension cylinder, a first extension cylinder, and a protective cylinder are also fitted on the surface of the sleeve. The third extension cylinder, the second extension cylinder, the first extension cylinder, and the protective cylinder are all connected by buckles and slots. As the screw continues to move upward, it will come into contact with the protective cylinder. After contacting the protective cylinder, it will also drive the protective cylinder to move upward. Because the buckle is smaller than the slot, when the protective cylinder moves upward to a certain height, the slot will limit the buckle, so that the first extension cylinder inside the protective cylinder will also move upward. Since the protective cylinder, the first extension cylinder, the second extension cylinder, and the third extension cylinder are all set by buckles and slots, as the screw continues to move upward, the protective cylinder, the first extension cylinder, the second extension cylinder, and the third extension cylinder will all move upward in sequence, thereby achieving the purpose of protecting the screw.
