Description

Technical Field

[0001] This utility model belongs to the technical field of planar gates in water conservancy projects. Specifically, it relates to a gate slider lifting device. Background Technology

[0002] The spillway system of a hydropower station dam's metal structure includes spillway tunnels, surface spillway outlets, central spillway outlets, and venting outlets. Each tunnel inlet is equipped with an emergency maintenance gate (mostly planar) and a working gate (mostly arc-shaped). The main supports for the maintenance gates are mostly made of bakelite sliders or oil-coated nylon. The advantages of bakelite sliders are that they do not damage the rails and are impact-resistant. Their disadvantages are that they are prone to aging, will form indentations under water pressure, and the friction coefficient of the friction pair increases and becomes very unstable. The current "Design Code for Steel Gates in Hydropower Projects" NB35055-2015 has removed bakelite sliders from the recommended sliders. Currently, bakelite slider manufacturers have ceased production. Nylon sliders have low strength, low load-bearing capacity, and an unstable friction coefficient. Oil-coated nylon materials have been verified through engineering practice to have many problems and have been removed from the "Manufacturing, Installation and Acceptance Code for Steel Gates in Water Conservancy and Hydropower Projects" DL / T5018-94.

[0003] Currently, planar gate sliding tracks are mostly replacing bakelite and nylon tracks with cast iron, steel, reinforced PTFE, steel-based copper-plastic composite materials, and engineering plastic alloys. Their material properties should comply with the "Specifications for Manufacturing, Installation and Acceptance of Steel Gates for Hydropower Projects" (NB / T35045-2014). The gate sliders in the matching sliding tracks are segmented. To comply with manufacturing processes, the joints between segments are tightly sealed without gaps, and adjacent sliders are connected seamlessly. There are no lifting points in the middle sections. Existing technology requires damaging the material itself to lift the sliders, and each slider needs to be lifted separately. Adjacent sliders are then matched and connected at the installation location, increasing labor intensity. Utility Model Content

[0004] The purpose of this utility model is to provide a gate slider lifting device to address the aforementioned shortcomings. This lifting device, due to its simple structure and convenient installation and disassembly, solves the problems of existing technologies where lifting sliders requires damaging the material itself, necessitates separate lifting, and requires matching and connecting adjacent sliders at the installation position, increasing labor intensity. To achieve the above objective, this utility model provides the following technical solution:

[0005] A gate slider lifting device includes a slider support assembly, a slider clamping assembly, and a lifting assembly; the slider support assembly is used to connect to the slider; the slider clamping assembly is used to limit the relative movement of the slider; and the lifting assembly is used to lift the slider to a designated position.

[0006] Furthermore, the slider clamping assembly includes a top plate and anti-tilt plates symmetrically connected on both sides of the top plate; the top plate is used to limit the vertical movement of the slider; the two anti-tilt plates are used to limit the horizontal movement of the slider.

[0007] Furthermore, the slider support assembly includes two adjusting screws, symmetrically arranged on both sides of the top plate, vertically penetrating the top plate; the bottom of each adjusting screw is integrally connected to a movable arm; a positioning pin locking screw is threaded onto the movable arm; the positioning pin locking screw vertically penetrates the movable arm; one end of the positioning pin locking screw is integrally connected to a positioning pin for insertion into the mounting bolt hole of the slider.

[0008] Furthermore, the positioning pin locking screw is provided with a positioning pin locking nut to prevent the positioning pin locking screw from loosening.

[0009] Furthermore, the adjusting screw is provided with a lower locking nut, which is located on the lower side of the top plate to restrict the upward movement of the adjusting screw.

[0010] Furthermore, the adjusting screw is provided with a locking nut, which is located on the upper side of the top plate to restrict the downward movement of the adjusting screw.

[0011] Furthermore, the anti-tilt plate is threaded with an anti-tilt locking screw; the anti-tilt locking screw passes through the anti-tilt plate; the two anti-tilt locking screws on the anti-tilt plates are locked by screwing them toward the middle contact slider.

[0012] Furthermore, the anti-tilt locking screw is provided with an anti-tilt locking nut to prevent the anti-tilt locking screw from loosening.

[0013] Furthermore, the anti-tilt locking screw and the positioning pin are arranged perpendicularly in the vertical direction.

[0014] Furthermore, the hoisting assembly includes lifting lugs that are fixed to the surface of the top plate.

[0015] The beneficial effects of this utility model are:

[0016] This application discloses a gate slider lifting device. A positioning pin is inserted into the mounting bolt hole of the connecting slider to form initial support. An adjusting screw, along with a lower locking nut and an upper locking nut, brings the top of the slider into contact with the top plate, restricting its vertical movement from both inside and at the top of the connecting slider. Anti-tilting plates and anti-tilting locking screws restrict the position of the connecting slider on both sides, limiting its horizontal movement and ensuring that the connecting slider, composed of two sliders, does not loosen, fall off, or tilt during lifting, preventing separation between the sliders. After the connecting slider is in place, the gate slider lifting device can be disassembled by loosening the locking nuts, without damaging the slider structure or requiring reassembly of two adjacent sliders at the installation location.

[0023] Example:

[0024] See attached Figures 1-3 This embodiment provides a gate slider lifting device that can lift two segmented sliders connected as a whole without damaging the sliders. This eliminates the need to reconnect the two segmented sliders at the installation location, reducing labor intensity. The lifting process is stable and less prone to loosening or tilting, and disassembly is simple, effectively improving the installation efficiency of gate sliders. It includes a slider clamping assembly, a slider support assembly, and a lifting assembly. The slider clamping assembly limits the movement of the sliders on both sides. Specifically, it includes a top plate 1 and anti-tilt plates 10 vertically and integrally connected at both ends of the top plate 1. The anti-tilt plates 10 have threaded through holes and are fitted with anti-tilt locking screws 9. The spacing between the locking screws on the two anti-tilt plates 10 can be adjusted by screwing, thereby fixing the slider supported between the two anti-tilt locking screws 9 and limiting its lateral displacement. Anti-tilt locking nuts 8 are provided on the anti-tilt locking screws 9 to fix them and prevent loosening.

[0025] In this embodiment, the slider support assembly includes two adjusting screws 3. Symmetrical through holes are provided on both sides of the top plate 1, through which the two adjusting screws 3 pass. A movable arm 7 is integrally connected to the bottom of each adjusting screw 3. The movable arm 7 is aligned downwards with the adjusting screw 3. A threaded through hole is provided on the movable arm 7, and a positioning pin locking screw 6 is vertically connected to it. A positioning pin 11 is integrally connected to the positioning pin locking screw 6. The positioning pin 11 and the anti-tilt locking screw 9 are perpendicularly distributed in the vertical projection, and the positioning pin 11 is located between the two anti-tilt plates 10. The positioning pin 11 can be directly inserted into the mounting bolt hole at the top of the slider.

[0026] In this embodiment, a positioning pin locking nut 12 is provided on the positioning pin locking screw 6 to prevent the positioning pin locking screw 6 from loosening.

[0027] In this embodiment, the adjusting screw 3 is provided with a lower locking nut 4, which is located on the lower side of the top plate 1 to restrict the upward movement of the adjusting screw 3.

[0028] In this embodiment, the adjusting screw 3 is provided with an upper locking nut 5, which is located on the upper side of the top plate 1 to restrict the downward movement of the adjusting screw 3. The lower locking nut 4 and the upper locking nut 5 can be used to fix the connecting slider on the positioning pin 11 at the position in contact with the top plate 1 and keep it locked.

[0029] In this embodiment, the hoisting component is a lifting lug 2, which is located in the middle of the upper surface of the top plate 1.

[0030] The hoisting process in this embodiment is as follows: Clean the joint surfaces and mounting surfaces of the gate slider sections on site. Place the gate slider with the mounting surface facing down on a rubber or wooden board. Insert the positioning pin 11 into the mounting bolt hole on the upper part of the slider. Connect the positioning pin locking screw 6 to the movable arm 7 and adjust the insertion depth of the positioning pin 11 to a suitable position to ensure that the top of the slider can contact the top plate 1 during vertical movement. Lock the positioning pin locking nut 12. After the adjusting screw 3 is connected to the top plate 1, move the slider upward until it is in close contact with the top plate 1. Lock the adjusting screw upper locking nut 5. Check whether the top plate 1, movable arm 7, and positioning pin 11 are firmly clamped and whether the joint surface between the top plate 1 and the top of the gate slider is fully fitted and without looseness. Then lock the adjusting screw lower locking nut 4. Lock the anti-tilting locking screws 9 on both sides of the anti-tilting plate 10 to the gate slider and lock the anti-tilting locking nut 8. Check whether the lifting equipment and the gate slider are fully locked. After confirming that there are no errors, the lifting and installation work can be carried out through the lifting lug 2 on the top plate 1. After hoisting to the designated position, directly remove the lower locking nut 4 of the adjusting screw, the upper locking nut 5 of the adjusting screw, the anti-tilting locking nut 8, and the locking nut 12 of the positioning pin, and then the entire lifting device can be removed from the slider.
