Abstract
The utility model relates to the technical field of cranes, in particular to a rotary encoder transmission device for a ship's crane. The rotary encoder transmission device is simple in structure and convenient to mount and maintain. The rotary encoder transmission device comprises an encoder, a shaft, and a transition sleeve, wherein the encoder is connected with the transition sleeve; the shaft is supported and mounted in the transition sleeve through two rolling bearings; one end of the shaft is connected with the shaft end of the encoder through a spring coupler; the other end of the shaft is connected with a left half pin shaft coupler; the left half pin shaft coupler is in transmission connection with a right half pin shaft coupler through three pin shafts; the right half pin shaft coupler is connected with a pinion through threads. The rotary encoder transmission device is simple in structure and affordable, can reduce the length of the transmission shaft of the encoder, provides convenience for a worker to mount, machine, and maintain the equipment.
Description
Technical field
The utility model relates to hoisting crane technical field, relates in particular to a kind of simple in structure, installation and maintenance deck crane rotary encoder driving device easily.
Background technology
Deck crane is to carry out a kind of special hoisting crane of hauling operation at sea in environment, is mainly used in the vital tasks such as transportation transfer, the replenishment at sea of goods between naval vessel, the input of under-water operation equipment and recovery.Marine special applied environment has brought very large challenge to the control of deck crane.On the one hand, similar land various driving crane equipment, needs the swing that produces in control load transportation, guarantees its positioning precision and conveying efficiency; On the other hand, because this hoisting crane is fixed on the motion platforms such as boats and ships, the sport of platform itself produces strong impact to load movement, and in a lot of situation, load lifting and the motion conditions at place, level point and the motion of crane itself are inconsistent.
Rotary encoder driving device on existing deck crane is that coder is fixed on to pedestal bottom plate center, and coder flange is arranged on center, hoisting crane tower body floor, drives coder rotation when tower body rotates, thereby obtains revolution number of turns technology.The shortcoming of existing apparatus is: due to the tower body base plate of hoisting crane and the height on pedestal floor higher, the transmission shaft of coder is very long, the installation that makes device acquires a certain degree of difficulty with processing tool, and device maintenance is also inconvenient.
Utility model content
Technical problem to be solved in the utility model is, overcomes the shortcoming of prior art, and a kind of simple in structure, installation and maintenance deck crane rotary encoder driving device is easily provided.In order to solve above technical matters, the utility model relates to a kind of deck crane rotary encoder driving device, comprise coder, axle and spacer shell, coder is connected with spacer shell, axle is arranged in spacer shell by two roller bearings, one end of axle is connected with coder axle head by spring coupling, the other end of axle is connected with left half bearing pin coupler, left half bearing pin coupler is by three bearing pins and right half bearing pin shaft coupling transmission, and right half bearing pin coupler is connected with miniature gears by screw thread.
The technical scheme that the utility model further limits is: on spacer shell, be fixed with mounting flange.
Further, described spacer shell is connected with coder by screw.
The beneficial effects of the utility model are: the utility model utilizes the constructional feature of miniature gears, miniature gears is connected with coder, make coder directly obtain the rotation number of turns of miniature gears, thereby finally obtain the revolution number of turns of hoisting crane, whole apparatus structure is simple, be convenient to installation and maintenance, economic and practical, will be widely used.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
The specific embodiment
The utility model provides a kind of deck crane rotary encoder driving device, comprise coder 1, axle 4 and spacer shell 3, coder 1 is connected with spacer shell 3 by screw, on spacer shell 3, be fixed with mounting flange 6, axle 4 is supported and is arranged in spacer shell 3 by two antifriction-bearing boxs 5, one end of axle 4 is connected with coder 1 axle head by spring coupling 2, the other end of axle 4 is connected with left half bearing pin coupler 7, left half bearing pin coupler 7 is by three bearing pins 8 and right half bearing pin coupler 9 transmissions, and miniature gears is connected by screwed with right half bearing pin coupler 9.
Encoder apparatus mounting flange 6 is arranged on the base plate of hoisting crane by support, coder 1 is driven by miniature gears and miniature gears rotating speed is carried out to synchronous counting, then calculates the final revolution number of turns that obtains hoisting crane by program.
In addition to the implementation, the utility model can also have other embodiments, and all employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
Claims (3)
1. a deck crane rotary encoder driving device, comprise coder, axle and spacer shell, it is characterized in that: described coder is connected with described spacer shell, described axle is arranged in described spacer shell by two roller bearings, one end of described axle is connected with described coder axle head by spring coupling, the other end of described axle is connected with left half bearing pin coupler, described left half bearing pin coupler is by three bearing pins and right half bearing pin shaft coupling transmission, and described right half bearing pin coupler is connected with miniature gears by screw thread.
