Description

Technical Field

[0001] The utility model relates to the technical field of gate keys, in particular to a telescopic gate key. Background Art

[0002] A sluice gate is a hydraulic engineering structure used to control water flow, typically in rivers, canals, or irrigation systems. A sluice key is the key used to operate the mechanical device that controls these gates. Currently, sluice keys used by water operators often suffer from issues such as being too long, being difficult to carry, and having their operating levers break.

[0003] It mainly manifests itself in the following aspects: First, in terms of valve depth, due to the different buried depths of valves in the water supply network and the fixed length of the existing integrated gate keys, the deepest valve that can be opened is about 1.6m deep. When encountering a deeper manhole, it cannot be used; second, in terms of material, the gate keys currently in use are made of galvanized steel pipes, which are insufficient in strength and are easy to break and twist when opening and closing the valves; third, in terms of structure, the existing gate keys adopt an integrated structure with a length of about 1.8m, which cannot be carried by conventional vehicles; fourth, in terms of valve specifications, due to the different specifications of gate heads of valves in the water supply network, the current gate key adapters are fixed in size, and it is often necessary to carry multiple gate keys, which brings inconvenience to construction operations; when the above problems occur, it is easy to prolong the emergency maintenance work of the water supply network, miss the best time for emergency maintenance, or cause greater water supply safety hazards.

[0029] Example

[0030] Reference Figure 1-Figure 5 , is a telescopic gate key disclosed in the utility model, comprising an outer rod 1, an inner rod 2, an operating rod 3 and a plurality of gate head assemblies 4 detachably connected to the inner rod 2;

[0031] The operating rod 3 is a round rod horizontally welded to the top of the outer rod 1. Specifically, the operating rod 3 is made of metal with a length of 600 mm and a diameter of 25 mm. The outer rod 1 and the inner rod 2 are both hexagonal tubes. The outer rod 1 is made of metal with a side length of 40 mm, a height of 32 mm, and a wall thickness of 4 mm. The inner rod 2 is made of metal with a side length of 31 mm, a height of 23 mm, and a wall thickness of 4 mm.

[0032] The inner rod 2 is slidably matched with the outer rod 1. Specifically, a first sliding cavity 5 is opened inside the outer rod 1, and both the top and the bottom are connected to the outside. The inner rod 2 is adapted to the first sliding cavity 5 and is vertically slidably connected to the first sliding cavity 5.

[0033] A first pin hole 6 is provided near the bottom of the outer rod 1. The first pin hole 6 is located 50 mm from the lowest end of the outer rod 1. A plurality of second pin holes 7 are provided on the inner rod 2, which can overlap with the first pin hole 6. The second pin holes 7 are vertically distributed. Specifically, the second pin holes 7 are respectively provided at 50 mm, 175 mm, 450 mm, 750 mm, and 1050 mm from the lowest end of the inner rod 2.

[0034] A hanging ear 8 welded to the outer wall of the outer rod 1 is provided at the first pin hole 6, and a hanging rope 9 is tied to the hanging ear 8. The other end of the hanging rope 9 is tied to a first pin shaft 10. The first pin shaft 10 is interference fit with the first pin hole 6 and the second pin hole 7. When the first pin hole 6 coincides with any second pin hole 7, the first pin shaft 10 is inserted into the first pin hole 6 and the second pin hole 7 to complete the fixation of the outer rod 1 and the inner rod 2.

[0035] The gate head assembly 4 includes a square rod 11 and a gate head fitter 12 welded to the bottom end of the square rod 11. A second sliding cavity 13 is provided inside the inner rod 2, and both the top and bottom ends are connected to the outside world. The second sliding cavity 13 slides with the square rod 11. The rod body of the square rod 11 is provided with a third pin hole 14 that coincides with the second pin hole 7.

[0039] The working principle and beneficial effects of the utility model are as follows:

[0040] When in use, the inner rod 2 is inserted into the outer rod 1. Since there are second pin holes 7 at different positions of the inner rod 2, the telescopic amount can be adjusted and fixed with the first pin shaft 10 to prevent the inner rod 2 from falling off. The gate head assembly 4 of the utility model can be replaced, so that gate head adapters 12 of different sizes can be replaced to open and close gates of different specifications.

[0041] After a long period of on-site trial, the modified telescopic gate key is suitable for opening and closing most valves. It is easy to carry and has no damage. It has a good effect. At the same time, the use of hexagonal tubes increases the torque between the outer rod 1 and the inner rod 2, enhances the strength of the gate key, successfully solves the shortcomings of the existing gate keys, and greatly improves the work efficiency of pipeline maintenance.
