Specific embodiment
As shown in Figure 1, a kind of hydraulic engineering headstock gear, including screw rod 1, headstock gear ontology 2 and gate 7, headstock gear sheet
Body 2 is worm-type open-close machine, and the lower section of headstock gear ontology 2 is welded with first base 3, and the lower section of first base 3 is provided with second
Pedestal 9.
The upper surface of second base 9 is provided with the second groove 8, and first base 3 is located in the second groove 8, and passes through two
The leveling component 4 at end is connected in the second groove 8, and leveling component 4 includes screw rod 402 and two fastening nuts 401, screw rod 402
Lower end be welded on the bottom surface of the second groove 8, the upper end of screw rod 402 extends vertically through first base 3, two fastening nuts 401
It is located at the upper and lower surface of first base 3, and screws cooperation with screw rod 402 and steps up fixed first base 3, passes through fastening nut
The gradient of 401 adjustable first bases 3 makes headstock gear ontology 2 and screw rod 1 in first base 1 reach suitable matching
State causes screw rod 1 to bend when preventing headstock gear ontology 2 from working.
After screw rod 1 sequentially passes through headstock gear ontology 2, first base 3 and second base 9 from top to bottom, lower end passes through slow
It rushes component 6 to connect with gate 7, Buffer Unit 6 includes lift lug 601 and fixes 604, and fixing seat 604 is mounted on lock by bolt
The upper end of door 7, lift lug 601 is welded in fixing seat 604, and the inside of lift lug 601 is disposed with mentions from top to bottom
Lift slab 602 and buffer spring 603,602 side wall of lifting plate are against on the inner wall of lift lug 601, prevent lifting plate 601 from occurring to turn
Dynamic, the lower end of screw rod 1 is welded after lift lug 601 with lifting plate 602, and screw rod 1 drives 602 slide downward of lifting plate, buffering
Spring 603 is then buffered from screw rod 1 to the pressure of gate 7, will be formed between screw rod 1 and gate 7 using buffer spring 603 soft
Property connection, solve the problems, such as extrusion shearing easy fracture of the connection bolt by screw rod 1.
In order to increase the protection to screw rod 1, corrosion of the external environment to screw rod 1 is prevented, is arranged with ripple on screw rod 1
Plastic tube 5, the upper and lower ends of waved plastic pipe 5 extend respectively on the opposite face of second base 9 and lift lug 601.
The utility model to install and use process as follows:
Firstly, second base 9 is mounted in cemented platform by bolt, it is then adjustable by fastening nut 401
The gradient of first base 3 makes headstock gear ontology 2 and screw rod 1 in first base 1 reach suitable matching status, prevents from opening
When closing the work of machine ontology 2, screw rod 1 is caused to bend.
When gate reaches bottommost, headstock gear ontology 2 continues that screw rod 1 is driven to push gate 7, will by Buffer Unit 6
Flexible connection is formed between screw rod 1 and gate 7, solves the problems, such as extrusion shearing easy fracture of the connection bolt by screw rod 1.
