Description

Technical Field

[0001] This utility model relates to the field of sluice gate engineering hoisting technology, specifically a protection device for sluice gate engineering hoisting. Background Technology

[0002] Gate hoists are mechanical devices used to control the opening and closing of gates in various large-scale water supply and drainage, water conservancy and hydropower projects. They can control the lifting and lowering of various large and medium-sized cast iron and steel gates to achieve opening and closing functions. There are many types of gate hoists, including deploying hydraulic gate hoists, winch gate hoists, gantry cranes, handwheel gate hoists, electric gate hoists, hand-cranked gate hoists, screw gate hoists, double-hanging gate hoists, etc. Existing gate hoists have many mechanical transmission structures. After long-term operation, the wear and tear between these mechanical structures generates heat, increasing not only the internal temperature of the gate hoist but also the wear between mechanical parts. Current technology requires periodically adding lubricating oil to the mechanical parts to reduce wear, but maintenance requires disassembling the casing, which is a cumbersome process.

[0003] To address the above issues, application number 202420159622.8, entitled "A Protective Device for a Sluice Gate Hoist," describes a device comprising a housing. Inside the housing, a central shaft is rotatably mounted. The lower end of the central shaft passes through the bottom surface of the housing and is fixedly connected to a screw post. A central gear is fixedly sleeved on the outer circumference of the central shaft. A motor housing is located on the outer side of the housing. The output end of a motor inside the motor housing extends into the housing and is fixedly connected to a drive pulley via a rotating shaft. Inside the housing, a high-speed rotating shaft is rotatably mounted via a connecting seat. A hollow shaft is fixedly spliced ​​to the upper end of the high-speed rotating shaft. When the high-speed rotating shaft drives the hollow shaft to rotate at high speed, centrifugal force is generated, causing the gear lubricating oil adhering to the lubricating oil adsorbent rod to disperse outward through multiple sets of micro-holes, reducing wear between mechanical parts. The movable cover facilitates the removal, placement, and replacement of the lubricating oil adsorbent rod, achieving a sufficiently smooth operation of the housing's mechanical structure.

[0004] Although this device can generate centrifugal force by driving the hollow shaft to rotate at high speed through a high-speed rotating shaft, causing the gear lubricating oil adhering to the lubricating oil adsorption rod to spread outward through multiple sets of micro-through holes, thereby lubricating the internal mechanical structure of the housing and reducing wear between components, it has obvious shortcomings in practical applications: On the one hand, this oiling method, which relies on centrifugal force to scatter the lubricating oil, makes it difficult to accurately focus on the meshing surface of the designated transmission gears or key lubrication points. A large amount of lubricating oil is easily splashed onto non-lubricated areas (such as the inner wall of the housing and the surface of non-transmission components), which not only fails to play a lubricating role but also causes serious waste of lubricating oil and increases maintenance costs; on the other hand, the lubricating oil adsorption rod equipped with the device has a limited adsorption capacity and can only store a small amount of lubricating oil. During continuous operation of the equipment, the lubricating oil on the adsorption rod will be quickly consumed through the through holes, causing the staff to frequently stop the machine to replenish the lubricating oil. This not only interrupts the normal operation rhythm of the equipment and reduces work efficiency, but also increases the labor intensity of the staff due to repeated disassembly and replenishment operations. Utility Model Content

[0005] The purpose of this section is to outline some aspects of the embodiments of this utility model and to briefly introduce some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be used to limit the scope of this utility model.

[0006] In view of the problems existing in the protection devices of the above and / or existing sluice gate project opening and closing machines, this utility model is proposed.

[0007] Therefore, the purpose of this utility model is to provide a protection device for the gate opening and closing mechanism of a sluice gate project.

[0008] To solve the above-mentioned technical problems, according to one aspect of the present invention, the present invention provides the following technical solution: A protective device for a sluice gate hoist includes a housing, a closed door connected to the front outer wall of the housing via a hinge, a mounting shell provided on the outer wall of the housing, a drive assembly provided inside the mounting shell, a handwheel rotatably connected to the top of the housing, a transmission rod provided at the bottom of the handwheel, and an oiling assembly for applying oil to the gear assembly fixedly connected to the inner wall of the housing.

[0009] As a preferred embodiment of the protective device for the sluice gate opening and closing machine of the present invention, the inner wall of the outer shell is rotatably connected to a transmission seat, and the driving assembly includes a drive motor installed inside the mounting shell.

[0010] As a preferred embodiment of the protective device for the sluice gate opening and closing machine described in this utility model, a transmission belt is sleeved between the output end of the drive motor and the transmission seat, and an end face gear is connected to the end of the transmission seat.

[0011] As a preferred embodiment of the protective device for the sluice gate opening and closing machine described in this utility model, a connecting rod and a gear are fixedly connected to the outer circumference of the transmission rod, and the gear meshes with the end face gear.

[0012] As a preferred embodiment of the protective device for the sluice gate opening and closing machine described in this utility model, a plurality of the connecting rods are connected to springs on their inner walls, and the ends of the springs are connected to moving blocks.

[0013] As a preferred embodiment of the protective device for the sluice gate opening and closing machine of the present invention, the bottom of the moving block is rotatably connected to a rotating rod, and the moving block is slidably connected inside the connecting rod.

[0014] As a preferred embodiment of the protective device for the sluice gate opening and closing machine of the present invention, the oiling assembly includes an installation plate installed on the inner wall of the outer shell, an oil storage cylinder connected to the end of the installation plate, a rotating block rotatably connected to the top of the oil storage cylinder, a spiral conveying rod provided at the bottom of the rotating block, and a connecting shell provided at the bottom of the oil storage cylinder.

[0015] As a preferred embodiment of the protective device for the sluice gate hoist described in this utility model, the outer wall of the connecting shell is provided with an oiling brush, and the outer wall of the connecting shell is also provided with an oil outlet hole.

[0016] As a preferred embodiment of the protective device for the gate hoist of the sluice gate project described in this utility model, the top of the oil storage tank is connected to an oil inlet hopper, and a sealing plug is threaded onto the top of the oil inlet hopper.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows: In actual use, the drive motor can be controlled by an external controller to rotate. The drive motor can drive the transmission rod to rotate through the action of the transmission belt, end face gear and gear. During the rotation of the transmission rod, it can drive the connecting rod to rotate, and then the rotating rod connected by springs inside the multiple connecting rods drives the rotating block to rotate, thereby driving the internal spiral conveying rod to rotate, so that it can continuously deliver and squeeze the lubricating oil inside the oil storage tank, and then discharge the lubricating oil from the oil outlet hole on the outer wall of the connecting shell. Then, the oil brush accurately applies it to the outer circumference of the gear. Compared with the centrifugal force swinging oil application method, the oil application method is more accurate and effectively reduces the waste of lubricating oil. When the sluice gate opening and closing machine rotates in reverse, since the multiple openings on the outer circumference of the rotating block are inclined, the moving block 222 can be driven to retract under the traction of the inclined surface through the action of the spring, thereby reducing the situation where the rotating block rotates in reverse due to the pressure of the rotating rod. The device is more stable in use and has a lower cost. In addition, compared with traditional lubricating oil adsorption rods, the oil storage tank 310 equipped with the device has a larger oil storage capacity, which can store enough lubricating oil to meet long-term lubrication needs. At the same time, the conveying method of the screw conveyor can ensure a uniform and stable supply of lubricating oil, avoiding the problem of oil supply interruption caused by the limited adsorption capacity of the adsorption rod. This design not only reduces insufficient lubrication or oil waste caused by unstable oil supply, but also eliminates the need for staff to frequently replace the lubricating oil adsorption rod, greatly shortening the operation and maintenance time, effectively improving the overall work efficiency, and reducing labor costs.

[0022] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views showing the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, in actual manufacturing, the three-dimensional spatial dimensions of length, width, and depth should be included.

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0024] This utility model provides a protective device for a sluice gate hoist, including a housing 100. A closed door 101 is connected to the front outer wall of the housing 100 via a hinge. A mounting shell 110 is provided on the outer wall of the housing 100. A drive assembly is provided inside the mounting shell 110. A handwheel 200 is rotatably connected to the top of the housing 100. A transmission rod 210 is provided at the bottom of the handwheel 200. An oiling assembly for applying oil to the gear assembly is fixedly connected to the inner wall of the housing 100.

[0025] In this embodiment: the outer shell 100 serves as the load-bearing frame of the entire protective device. It is made of high-strength metal materials (such as stainless steel and carbon steel), possessing excellent corrosion and impact resistance, and effectively isolating external dust, rainwater, mud, and other impurities from corroding the internal transmission components. Its inner wall is pre-set with fixing holes and support structures according to the installation requirements of each component, ensuring stable installation of components such as the drive assembly, lubrication assembly, and transmission seat. The outer wall has a pre-reserved connection interface for the mounting shell 110, ensuring the compactness of the overall structure. The closed door 101 is rotatably connected to the front outer wall of the outer shell 100 via a hinge, enabling opening and closing operations, facilitating maintenance, repair, or cleaning of waste lubricating oil from the internal components. When the closed door 101 is closed, it forms a complete enclosed space with the outer shell 100, further enhancing the protective effect. Sealing strips can be installed on the door edges to improve waterproof and dustproof performance. A door lock structure can also be provided to prevent unauthorized opening, ensuring equipment safety.

[0026] Specifically, a transmission seat 120 is rotatably connected to the inner wall of the outer casing 100, and the drive assembly includes a drive motor 111 installed inside the mounting casing 110.

[0027] In this embodiment: the mounting shell 110 is fixed to the outer wall of the outer shell 100, providing an independent installation and protection space for the drive motor 111, preventing the motor from being directly exposed to the external environment. The inner wall of the mounting shell 110 can be equipped with shock-absorbing pads to reduce the transmission of vibrations generated during the operation of the drive motor 111, reduce noise, and protect the internal components of the motor. Heat dissipation holes are provided on the shell wall, working in conjunction with the motor's own heat dissipation structure to ensure the heat dissipation needs of the motor during long-term operation and prevent malfunctions due to overheating.

[0028] Specifically, a transmission belt 112 is sleeved between the output end of the drive motor 111 and the transmission base 120, and an end face gear 130 is connected to the end of the transmission base 120.

[0029] Specifically, a connecting rod 220 and a gear 230 are fixedly connected to the outer circumference of the transmission rod 210, and the gear 230 meshes with the end face gear 130.

[0030] In this embodiment: the drive motor 111 serves as the power source for the gate hoist and is installed inside the mounting housing 110. Its selection is determined based on the load requirements of the gate hoist, ensuring sufficient torque and speed adjustment capabilities. A transmission belt 112 (preferably a wear-resistant, tensile-resistant rubber synchronous belt or V-belt) is fitted between the output end of the drive motor 111 and the transmission seat 120, which is rotatably connected to the inner wall of the housing 100. Power transmission is achieved through the friction of the transmission belt 112. This belt drive method features shock absorption, smooth operation, and low noise. Furthermore, the transmission belt can slip under overload conditions, preventing damage to the motor and transmission components due to overload and providing overload protection. The transmission seat 120 is rotatably connected to the inner wall of the housing 100 via bearings. One end of the transmission seat 120 engages with the transmission belt 112 to receive the power transmitted by the drive motor 111, while the other end is fixedly connected to the end face gear 130, realizing the conversion of power direction and torque transmission. The end face gear 130 is made of high-strength alloy material, and the tooth surface is hardened, which has good wear resistance and load-bearing capacity. Its tooth profile design matches the gear 230 on the transmission rod 210 to ensure the accuracy and stability of meshing transmission and avoid problems such as tooth skipping and jamming.

[0031] Specifically, springs 221 are connected to the inner walls of multiple connecting rods 220, and moving blocks 222 are connected to the ends of springs 221.

[0032] Specifically, the bottom of the movable block 222 is rotatably connected to a rotating rod 223, and the movable block 222 is slidably connected inside the connecting rod 220.

[0033] Specifically, the oiling assembly includes a mounting plate 300 installed on the inner wall of the housing 100, an oil storage cylinder 310 connected to the end of the mounting plate 300, a rotating block 320 rotatably connected to the top of the oil storage cylinder 310, a spiral conveying rod 330 provided at the bottom of the rotating block 320, and a connecting shell 340 provided at the bottom of the oil storage cylinder 310.

[0034] In some embodiments, the outer circumferential wall of the rotating block 320 is provided with a plurality of inclined openings, the inclined openings being right-angled trapezoids.

[0035] Specifically, the outer wall of the connecting shell 340 is provided with an oiling brush 341, and the outer wall of the connecting shell 340 is also provided with an oil outlet hole 342.

[0036] Specifically, the top of the oil storage tank 310 is connected to an oil inlet 350, and the top of the oil inlet 350 is threaded with a sealing plug 360.

[0037] In this embodiment: the connecting shell 340 is fixedly connected to the bottom of the oil reservoir 310, communicating with the interior of the oil reservoir 310, and ensuring that the oiling brush 341 can closely adhere to the gear surface. The oiling brush 341 is made of wear-resistant, oil-absorbent fiber material (such as nylon), fixed to the outer wall of the connecting shell 340, with its bristles directly contacting the tooth surface of the gear 230. An oil outlet hole 340 is also provided on the outer wall of the connecting shell 340, the position of which corresponds to the oiling brush 341. The lubricating oil in the oil reservoir 310 is transported to the connecting shell 340 via the screw conveyor 330, seeps out through the oil outlet hole 340, and is adhered to by the oiling brush 341. Subsequently, during gear rotation, the oiling brush 341 evenly coats the lubricating oil onto the tooth surface, achieving lubrication of the meshing parts. The diameter of the oil outlet hole 340 can be set according to the viscosity of the lubricating oil and lubrication requirements, ensuring that the oil seepage rate matches the gear lubrication needs.

[0038] In some embodiments, the device can be controlled by an external controller and powered by an external power source.

[0039] In this embodiment, during the lubrication operation, the operator can control the start / stop and speed of the drive motor 111 via an external controller. After the drive motor 111 starts, the power is transmitted to the end face gear 130 via a transmission belt, and then the transmission rod 223 is driven to rotate through the meshing of the gear 230. When the transmission rod 223 rotates, it synchronously drives multiple sets of connecting rods 220 to rotate. The rotating rod 223 connected inside the connecting rod 220 by the spring 221 is linked accordingly, thereby driving the rotating block 320 to rotate, and finally driving the screw conveyor rod 330 to operate continuously. During the rotation of the screw conveyor rod 330, it can transport the lubricating oil stored in the oil storage tank 310. A stable conveying and extruding force is formed, pushing the lubricating oil at a uniform speed to the oil outlet 340 on the outer wall of the connecting shell 340 and discharging it in an orderly manner. The discharged lubricating oil directly adheres to the oiling brush 341. Through the contact between the oiling brush 341 and the outer circumference of the transmission gear, the lubricating oil is evenly and accurately applied to the meshing surface of the gear 230. Compared with the traditional centrifugal force-driven oiling method, this directional conveying and brush-coating design completely avoids the problem of lubricating oil scattering and splashing, ensuring that the lubricating oil only acts on the target lubrication point, greatly reducing oil waste, and reducing oil accumulation in non-lubricated areas; for the reverse rotation of the sluice gate hoist in the sluice gate project. Under special operating conditions, this device achieves improved operational stability through structural design. Multiple openings on the outer circumference of the rotating block 320 are arranged in an inclined layout. When the hoist reverses, potentially causing the rotating block to rotate in the opposite direction, the inclined openings and the elastic force of the spring 221 work together. The spring 221 retracts due to its own recoil characteristics, moving along the inclined surface of the opening. This prevents the rotating block 320 from being blocked or obstructed, effectively suppressing its reverse rotation and avoiding disruption of lubricant delivery or component jamming caused by reverse rotation of the screw conveyor. This ensures the device operates smoothly in both forward and reverse directions. It can operate stably under all working conditions, further reducing the risk of equipment failure and maintenance costs. In addition, compared with traditional lubricating oil adsorption rods, the oil storage tank 310 equipped with the device has a larger oil storage capacity, which can store enough lubricating oil to meet long-term lubrication needs. At the same time, the conveying method of the screw conveyor can ensure a uniform and stable supply of lubricating oil, avoiding the problem of oil supply interruption caused by the limited adsorption capacity of the adsorption rod. This design not only reduces insufficient lubrication or oil waste caused by unstable oil supply, but also eliminates the need for staff to frequently replace the lubricating oil adsorption rod, greatly shortening the operation and maintenance time, effectively improving the overall work efficiency, and reducing labor costs.

[0040] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
