Abstract
The utility model discloses a totally-enclosed hand screw type gate hoist, and relates to the technical field of hoists for hydraulic gates. The totally-enclosed hand screw type gate hoist comprises a seat, a lead screw, a nut, a hand rod, a shell and a transmission subassembly, wherein the transmission subassembly is arranged in the shell; the shell is connected with the seat through bolts; the transmission subassembly comprises a first gear, a second gear and a lead screw subassembly; the first gear is meshed with the second gear and is detachably connected with a crank through a crank shaft; the second gear sleeves the lead screw subassembly; the top of the lead screw is fixedly connected with the shell through a bearing; a lead screw protection cover is arranged on the periphery of the lead screw; and the upper end of the lead screw protection cover is perpendicularly connected to the top of the inside of the seat. The totally-enclosed hand screw type gate hoist is simple in structure, convenient to use and high in closure; the lead screw protection cover is arranged on the periphery of the lifting screw, so that windy sand can be stopped, dust can be prevented from entering a tube wall of the lead screw, and the safety of the gate hoist is improved when the gate hoist is used.
Description
Technical field
The utility model relates to hydraulic gate headstock gear technical field, relates in particular to a kind of totally-enclosed hand worm-type open-close machine.
Background technology
The hand worm-type open-close machine of general use in the engineerings such as small-sized agricultural land water conservancy irrigation, aquatic farm, urban water supply and sewerage, irrigated area transformation at present, but existing hand worm-type open-close machine top narrow space, will precocity gate when screw mandrel can not rise can not all open and affect the use of gate, owing to being that outdoor study is used, dust storm, dust are easy to enter into the tube wall inside of screw mandrel.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of simple in structure, easy to use, totally-enclosed hand worm-type open-close machine that closure is good.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: a kind of totally-enclosed hand worm-type open-close machine, mainly comprise support, screw mandrel, nut, joystick, casing and the transmission component that is arranged on casing inside, described casing is connected with described support by bolt, described transmission component comprises the first gear, the second gear and screw component, described the first gear engages with the second gear, described the first gear removably connects by crank shaft and described crank, described screw component is sleeved on described the second gear inside, described screw mandrel top is fixedly connected with described casing by bearing, described screw mandrel is arranged with screw mandrel protective cover outward, described screw mandrel protective cover upper end is vertically connected on the inner tip of described support.
Preferably, described crank shaft is radially connected with protection side cover, and described protection side is arranged with the cavity suitable with described crank handle sleeve barrel.
The beneficial effect that adopts technique scheme to produce is: the utility model is simple in structure, easy to use, closure is good, the screw component arranging by inside is realized screw mandrel and is not risen and gate can be risen at casing internal rotating, while having avoided can not rising because of headstock gear top narrow space screw mandrel, cause gate all not open and affect the use of gate, by installing screw rod protective sleeve additional in elevating screw periphery, can keep the sand in check and avoid dust to enter in the tube wall of screw mandrel, crank shaft and crank link are provided with special auxiliary equipment, only has so suitable special-purpose cranking bar ability open-close sluice gate, avoid open-close sluice gate in unwarranted situation, improve headstock gear safety in use.
