Description

Technical Field

[0001] This utility model relates to the field of water conservancy and hydropower technology, and more specifically, to a gate lifting device. Background Technology

[0002] Gate lifting devices are core equipment for controlling the opening and closing of gates, and are widely used in water conservancy projects, municipal water supply and drainage, power stations, and other fields. Screw-type gate lifting devices are commonly used opening and closing equipment in water conservancy projects. They mainly consist of a screw, nut, power drive device, base, limit device, etc. When it is necessary to open or close the gate, in manual operation, the operator turns the crank handle, which causes the nut to rotate through a gear transmission mechanism. The threaded engagement between the nut and the screw converts the rotational motion into the linear motion of the screw, driving the gate connected to it to rise or fall. In electric operation, the motor drives the nut to rotate through a reduction gear, which also enables the screw to drive the gate to rise or fall. The limit device sends a signal in time when the gate reaches the predetermined position to stop the device from operating, thereby controlling the water flow. Since the screw is an important component in the gate lifting process, it is necessary to carry out lifting protection operations.

[0003] In related technologies, during the use of gate lifting devices, workers typically perform regular maintenance on the screw, including removing dirt and applying lubricating oil to protect the screw surface before use.

[0004] However, during the current use of gate lifting devices, because the top of the screw is directly exposed on the outside of the base, it is very easy for external rain, snow, dust and other dirt to directly adhere to the screw surface, which leads to accelerated erosion and aging of the screw surface, interfering with the opening and closing accuracy and stability of the gate lifting device. In severe cases, it may even cause safety accidents, affecting the use protection and stability of the gate lifting device. Utility Model Content

[0020] Reference Figures 1-4This utility model provides a technical solution: a gate lifting device, including a base 1 and an interval protection mechanism. A screw 2 is installed on the top inside the base 1, and a rotating head 3 is installed on the front left side of the base 1. A medium can be formed on the outside of the screw 2 at the top of the base 1 to provide interval protection for the screw 2, so that the user can perform interval protection work on the screw 2 and avoid external rain, snow, dirt and other impurities from directly adhering to the surface of the screw 2, which would lead to accelerated corrosion and aging of the screw 2 surface and affect the opening and closing accuracy and stability. Therefore, the use protection and stability of the screw 2 are improved.

[0021] Reference Figures 1-4 In a preferred embodiment, the spacer protection mechanism includes a spacer cylinder 4, which is movably connected to the outside of the screw 2. A protective cover 5 is movably connected to the outside of the spacer cylinder 4. A fixing frame 6 is fixedly connected to both sides of the bottom of the outside of the spacer cylinder 4. A fixing plate 7 is movably connected to the inside of the fixing frame 6. A protective lifting mechanism is movably connected to the inside of the protective cover 5. The spacer cylinder 4 and the protective cover 5 are moved to the top of the base 1, and the spacer cylinder 4 and the protective cover 5 are fitted onto the outside of the screw 2, with the fixing plate 7 located on the outside of the base 1. The fixed plate 7 is moved to contact and abut against the base 1, thus performing the installation and connection work between the spacer cylinder 4 and the base 1, so that the protective cover 5 and the spacer cylinder 4 are at the top of the base 1 and the screw 2. The outer side of the rod 2 forms a protective medium that can be raised and lowered to surround the spacer. The protective lifting mechanism includes a lifting cylinder 8, a lifting groove 9, and a lifting block 10. The lifting cylinder 8 is movably connected to the inner side of the protective cover 5. The lifting groove 9 is respectively opened on the surface of the lifting cylinder 8 and the spacer cylinder 4. The lifting block 10 is movably connected to the inside of the lifting groove 9. The lifting block 10 is connected to the lifting cylinder 8 and the protective cover 5 respectively, which can perform lifting and lowering connection work between the protective cover 5 and the spacer cylinder 4, and perform lifting and lowering expansion work between the protective cover 5 and the spacer cylinder 4. This avoids the situation where the spacer cylinder 4 and the protective cover 5 are difficult to lift and lower during use, thus improving the lifting and lowering connection effect and protection range of the protective cover 5 and the spacer cylinder 4.

[0022] Reference Figures 2-3 In a preferred embodiment, mounting holes 11 are provided on the outer sides of both the protective cover 5 and the lifting cylinder 8. The mounting holes 11 are movably connected to mounting bolts 12 that are threadedly connected to the lifting block 10. This allows for the installation and connection of the lifting block 10 with the protective cover 5 and the lifting cylinder 8, avoiding situations where the lifting block 10 is difficult to connect with the protective cover 5 and the lifting cylinder 8 during use. This improves the installation and connection effect of the lifting block 10 with the protective cover 5 and the lifting cylinder 8. A centering cylinder 13 is provided inside the spacer cylinder 4. The top of the centering cylinder 13 is fixedly connected to the top of the inner wall of the protective cover 5. This allows for the centering of the protective cover 5 and the screw 2 during installation, preventing excessive offset of the protective cover 5 during use. This improves the ease of installation of the protective cover 5.

[0023] Reference Figures 2-4 In a preferred embodiment, a screw hole 14 is provided on the outer side of the fixing frame 6, and a stud 15 is threaded inside the screw hole 14. The inner side of the stud 15 is connected to the outer side of the fixing plate 7, which can connect the fixing plate 7 and the fixing frame 6 and provide a medium for the user to apply a clamping force to the fixing plate 7. This avoids the situation where the fixing plate 7 is difficult to clamp or separates from the fixing frame 6 during use, thus improving the connection effect and clamping effect between the fixing plate 7 and the fixing frame 6. A connecting shell 16 is fixedly connected to the top and bottom of the outer side of the fixing plate 7. A connecting seat 17 is movably connected inside the connecting shell 16. The outer side of the connecting seat 17 is fixedly connected to the inner side of the stud 15, which can perform rotational connection between the stud 15 and the fixing plate 7 to prevent displacement and separation. This avoids the situation where the stud 15 separates from the fixing plate 7 during use, thus improving the connection effect between the stud 15 and the fixing plate 7.

[0024] Reference Figures 2-4 In a preferred embodiment, a magnetic sheet 18 is embedded and connected to the outer side of the fixed plate 7, and a magnetic suction sheet 19, which is magnetically connected to the magnetic sheet 18, is embedded and connected to the inner side of the connecting seat 17. The connecting seat 17 can magnetically connect the stud 15 and the fixed plate 7, avoiding the stud 15 from rotating easily during use. This improves the connection effect between the stud 15 and the fixed plate 7. A rubber pad 20 is movably connected to the inner side of the fixing frame 6. The outer side of the rubber pad 20 is fixedly connected to the inner side of the fixed plate 7. This can provide clamping contact anti-slip and protection between the fixed plate 7 and the machine base 1, preventing the fixed plate from slipping when clamping force is applied during operation. This improves the clamping anti-slip and protection effect of the fixed plate 7.

[0025] Specifically, the working process or principle of the gate lifting device is as follows: During use, the handheld fixing frame 6 moves the spacer cylinder 4, causing the lifting cylinder 8 and protective cover 5 to move to the top of the base 1. At this time, the centering cylinder 13 moves with the protective cover 5, aligning with the screw 2. Then, the spacer cylinder 4 is moved downwards and placed on the top of the base 1, fitting the spacer cylinder 4 onto the outside of the screw 2. At this time, the centering cylinder 13 fits onto the outside of the screw 2 surface, thus centering and guiding the screw 2 and the protective cover 5. Subsequently, the handheld stud 15 is rotated. With the screw hole 14 in place, a threaded thrust is applied to the fixing plate 7 to move it inward, causing the fixing plate 7 to bring the rubber pad 20 into contact with the surface of the machine base 1, thus clamping and fixing the spacer cylinder 4 to the machine base 1. During this process, since the top of the fixing plate 7 contacts the top of the inner side of the fixing frame 6, the fixing plate 7 can be moved and guided to ensure that its position does not shift during movement. At this time, the connecting seat 17 rotates inside the connecting shell 16 with the stud 15, thus rotatably connecting the stud 15 and the fixing plate 7. Simultaneously, the magnetic sheet 18 is equipped with... The magnetic chuck 19 connects the stud 15 and the fixed plate 7 via the connecting seat 17. When the operator provides the rotary head 3 to drive the screw 2 to lift and lower the external gate, the protective cover 5 moves upward along with the screw 2 after the top of the screw 2 contacts the top of the inner wall of the protective cover 5. At this time, the lifting block 10 moves inside the lifting groove 9 along with the protective cover 5 through the mounting hole 11 and the mounting bolt 12, connecting the protective cover 5 and the lifting cylinder 8. After the lifting block 10 connected to the protective cover 5 moves into the lifting groove 9, the protective cover... 5. As it continues to rise, the lifting block 10 inside the protective cover 5, in conjunction with the lifting groove 9, applies an upward pulling force to the lifting cylinder 8, causing the lifting cylinder 8 to move upward with the protective cover, thus expanding the protective enclosure interval between the protective cover 5 and the spacer cylinder 4. At the same time, the lifting block 10 inside the lifting cylinder 8 moves with the lifting cylinder 8 inside the lifting groove 9, performing lifting and lowering connection work between the lifting cylinder 8 and the spacer cylinder 4, causing the spacer cylinder 4 to cooperate with the lifting cylinder 8 and the protective cover 5 to enclose and protect the screw 2, preventing external rain, snow and dirt from directly corroding the screw 2.

[0026] It should be noted that the base 1, screw 2 and rotor 3 are all existing devices or equipment, or devices or equipment that can be implemented with existing technology. Their power supply, specific composition and principle are clear to those skilled in the art, so they will not be described in detail.
