Technical Field

[0001] This utility model relates to the field of screw-type gate hoist protection technology, and in particular to a screw-type gate hoist protection device. Background Technology

[0002] Screw-type gate hoists, as key equipment in water conservancy projects, undertake the important tasks of controlling water flow, regulating water level, and ensuring the safe operation of sluice gates. The gate hoist 2 is fixedly installed on the operating platform 1. Driven by a transmission mechanism, the meshing gear set rotates, driving the screw 3 of the hoist to move up and down rhythmically. This causes the gate to move up and down within the gate slot, achieving the purpose of controlling water flow through gate opening and closing. Open-air screw-type gate hoists have advantages such as simple installation and convenient disassembly. However, their disadvantage is that the hoist and screw are exposed, making them susceptible to damage from external impacts, such as damage to the motor housing or bending deformation of the screw. To address these shortcomings, this application proposes a protective device for screw-type gate hoists. Utility Model Content

[0027] Covering part 20. Detailed Implementation

[0028] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0029] Example 1:

[0030] Please see Figure 1 , 2 A protective device for a screw-type gate hoist includes a protective structure 10, which is installed on an operating platform 1 and located above the gate hoist 2. The protective structure 10 includes a support part 11 and a cover part 12, with the cover part 12 fixedly mounted on the support part 11. The cover part 12 has a through hole 13 for the screw 3 to pass through. By installing the protective structure 10 on the operating platform 1, the screw-type gate hoist is protected, thus solving the problem of easy damage to the screw-type gate hoist when installed outdoors.

[0031] In one of the solutions, see Figure 3 The support portion 11 has at least three legs. Specifically, there are three or four legs. The lower ends of the legs are connected and fixed to the operating platform 1, and the cover portion 12 is fixed to the upper ends of the legs.

[0032] In another option, see Figure 4 The support portion 11 has a cylindrical structure. The cylindrical support portion 11 includes a circular structure, or... Figure 4 The convex structure shown can be a polygonal cylindrical structure or a cylindrical structure with other irregular cross-sections.

[0033] The support part 11 and the cover part 12 can be made of concrete, stone or metal.

[0034] When a concrete structure is used, the connection and fixation of the support part 11 and the cover part 12 can be made by cement mortar, and the support part 11 can be cast on the operating platform 1.

[0035] When a stone structure is used, the connection and fixation of the support part 11 and the cover part 12 can be made by gluing with marble adhesive, and the lower end of the support part 11 can be pre-embedded in the operating platform 1.

[0036] When a metal structure is used, the connection and fixation of the support part 11 and the cover part 12 can be achieved by welding or bolt splicing. The lower end of the support part 11 can be pre-embedded in the operating platform 1 or connected and fixed to the operating platform 1 by anchor bolts.

[0037] When the support part 11 is a cylindrical structure, see Figure 4The bottom of the support part 11 is provided with a bottom cover 14, and the bottom cover 14 is provided with a clearance hole 141. By fixing the bottom cover 14, the structural strength of the support part 11 is improved, and the clearance hole 141 is used to avoid the hoist 2.

[0038] Furthermore, a window 15 is provided on the support part 11 to facilitate maintenance of the hoist 2 through the window 15.

[0039] Preferably, the cover 12 is a circular or polygonal structure. In specific applications, the cover 12 can be made into any shape as needed, such as an ellipse.

[0040] Example 2:

[0041] Based on Example 1, see Figure 5 The present invention also includes a top cover 16, which is installed at the upper end of the screw 3. When the screw 3 is in the lower limit position, the top cover 16 is located inside the through hole 13. The top cover 16 can be sleeved on the top of the screw 3 or screwed onto the top of the screw 3 with a threaded connection.

[0042] Preferably, when the screw 3 is in the lower limit position, the top cover 16 is located inside the through hole 13, and the upper side of the top cover 16 is flush with the upper side of the cover portion 12, thereby sealing the through hole 13 and preventing debris from falling into the through hole 13. When the screw 3 extends upward, the top cover 16 also rises accordingly.

[0043] Example 3:

[0044] The difference from Embodiment 2 is that a top cover 16 is movably installed in the through hole 13, a flange 161 is provided on the upper outer wall of the top cover 16, and an annular platform 131 is provided on the upper side of the through hole 13. When the screw 3 is in the lower limit position, the flange 161 is placed on the annular platform 131.

[0045] When the screw 3 is at its lower limit position, the flange 161 rests on the ring platform 131, and the upper side of the top cover 16 is flush with the upper side of the cover 12, thus sealing the through hole 13. This structure allows for greater flexibility in the lower limit position of the screw 3 and improves its applicability. When the screw 3 extends upwards, it lifts the top cover 16.

[0046] Example 4:

[0047] Based on Example 1, 2, or 3, see [link to example]. Figure 1 The operating platform 1 is also equipped with a cover 20, which covers the protective structure 10. The cover 20 is used to shield against rainwater.

[0048] In this embodiment, the covering part 20 adopts a pavilion structure.

[0049] Example 5:

[0050] See Figure 1 The protective structure 10 uses a stone table, with stone benches placed around it. A pavilion structure 20 is then installed on top, which not only ensures the original functionality and safety of the hoist, but also enhances the aesthetic appeal of the water conservancy project's river and lake structures, making them a unique and beautiful feature of the river and lake landscape and providing a convenient place for tourists and leisure visitors to rest.
