Specific implementation mode

[0017] Referring to Figures 1 to 6 , it can be understood from the structure in the figure an implementation process of the present utility model applicable to arc gates of various widths for use.

[0018] An arc gate hoist includes two sets of mirror - image - arranged driving mechanisms. Each set of driving mechanisms includes a square column 01 with a round shaft 02 provided at the inner end. A swivel ring 04 is rotatably connected to the round shaft 02. A hydraulic cylinder 05 is provided at the outer end of the swivel ring 04. The square column 01 is in sliding contact with the square pipe 11. A connecting plate 15 is fixedly connected to the inner side of the square pipe 11. The two sets of driving mechanisms can be respectively fixed on the inner walls on both sides of the water channel, so that the two square pipes 11 are respectively embedded in the inner walls on both sides of the water channel made of concrete and are in a mirror - symmetric state. Subsequently, by sliding the square column 01 in each square pipe 11, the square column 01 can be telescoped to change the distance between the two square columns 01, so that the square column 01 can drive the hydraulic cylinder 05 on the swivel ring 04 to adjust the distance, and thus it can meet the requirement that arc gates of different widths can be connected to the hydraulic cylinder 05 to drive the arc gate to open and close through the hydraulic cylinder 05. Further, by using expansion bolts, the connecting plate 15 can be fixed on the concrete side walls on both sides of the water channel, thereby improving the connection strength between the square pipe 11 and the side wall of the water channel and preventing it from falling off.

[0019] Referring to Figures 1 to 6 , it can be understood from the structure in the figure an implementation process of fixing the telescopic amount in the present utility model.

[0020] A through hole 12 is opened at the upper end inside the square pipe 11, and a plurality of blind holes 16 are spaced apart at the upper end of the square column 01. A pin 13 that can be inserted into any one of the blind holes 16 is in sliding contact in the through hole 12. When adjusting the telescopic amount of the square column 01 in the square pipe 11, first take out the pin 13. After the adjustment is completed, when the blind hole 16 on the square column 01 is aligned with the through hole 12, insert the pin 13 into the blind hole 16 and the through hole 12, thereby fixing the telescopic amount of the square column 01 in the square pipe 11.

[0021] Referring to Figures 1 to 6 , it can be understood from the structure in the figure an implementation process of improving the connection strength in the present utility model.

[0022] Threads are provided on the outer side of the plug pin 13 and the inner wall of the through hole 12. After the plug pin 13 is connected to the through hole 12, the plug pin 13 can be made to extend into the blind hole 16 more firmly through the action of the threads, avoiding the plug pin 13 from falling due to vibration or other reasons, and improving the restriction and fixation of the plug pin 13 on the square column 01.

[0023] Referring to Figures 1 to 6 , it can be understood from the structure in the figure an implementation process of connecting the arc gate in the present utility model.

[0024] A round sleeve 06 is provided on the hydraulic rod of the hydraulic cylinder 05. A rotating column 07 is rotatably connected in the round sleeve 06, and a hanging plate 08 is fixedly connected to the rotating column 07; during installation, the hanging plate 08 can be connected to the middle of the arc gate frame through bolts, thus achieving the effect of quick disassembly and connection. During the process of the telescopic movement of the hydraulic rod of the hydraulic cylinder 05, the rotating column 07 can adaptively rotate in the round sleeve 06.

[0025] Referring to Figures 1 to 6 , it can be understood from the structure in the figure an implementation process of connecting the end of the arc gate support in the present utility model.

A round sleeve 06 is provided on the hydraulic rod of the hydraulic cylinder 05, and a bottom shaft 09 is fixedly connected in the round sleeve 06. The end of the bottom shaft 09 is rotatably connected to a support plate 10; by connecting the end of the arc gate support to the support plate 10 through bolts, the end of the arc gate can be fixed and can only rotate around the bottom shaft 09 during opening and closing. Additionally, the hydraulic rod of the hydraulic cylinder 05 can drive the bottom shaft 09 to adjust the height, and different lengths of arc gate supports can be installed to meet the use of different models of arc gates.

[0027] Referring to Figures 1 to 6 , it can be understood from the structure in the figure an implementation process of being convenient for maintenance in the present utility model.

[0028] Both the rotating ring 04 and the inclined block 03 are detachably connected to the hydraulic cylinder 05 through bolts; the round sleeve 06 and the hydraulic rod of the hydraulic cylinder 05 are detachably connected through bolts. Through the detachable connection method, it is convenient to maintain each component and perform overall assembly and other work.

[0030] A number of evenly spaced grooves 14 are provided on the side wall of the square pipe 11. When using concrete to build the side wall of the water channel, the square pipe 11 can be embedded therein, and the grooves 14 are used to allow the concrete to enter, increasing the connection area and ability between the outer wall of the square pipe 11 and the concrete, thereby improving the connection strength between the square pipe 11 and the side wall of the water channel.

[0031] Refer to Figures 1 to 6 , it can be understood from the structure in the figure an implementation process of improving the service strength in the present utility model.

[0032] The square column 01, the round shaft 02, the inclined block 03, the hanging plate 08, the bottom shaft 09, the support plate 10 and the square pipe 11 are all made of high-strength wear-resistant steel, which can reduce daily wear by its own strength and can also avoid deformation; further, the surfaces of the components in the driving mechanism are all sprayed with waterproof paint, which can avoid damage caused by water corrosion to the components during long-term use.
