Description
Technical field
The invention belongs to the hoisting crane technical field, particularly relate to a kind of chain-driving hoisting crane that is used for the specific safety place.
Background technology
At present, hoisting crane is widely used in fields such as Aeronautics and Astronautics, nuclear power.And some special place, in the high radiation factory building like nuclear power, because common hoisting crane is arranged in motor in the factory building, electric wire etc. also will be arranged in the factory building so.In case problems such as aging appear in electric wire, the replacing that needs repairing because environment is special, is the environment of the high radiation of high temperature, personnel can not get into, and conventional hoist can't satisfy the specific (special) requirements in this special place.
Summary of the invention
The present invention provides a kind of chain-driving hoisting crane that is used for the specific safety place for solving the technical matters that exists in the known technology; This crane structure is simple, safety precaution good, need not laying wire laying in factory building, and the maintainer does not get into factory building inside and just can keep in repair hoisting crane.
The technical scheme that the present invention takes for the technical matters that exists in the solution known technology is:
A kind of chain transmission crane that is used for the specific safety place; Comprise cart, at reciprocating dolly on the cart be installed in the elevating mechanism on the dolly; It is characterized in that: cart is installed on the cart chain that is supported by cart drive sprocket and cart support sprocket wheel by moving sprocket wheel; Lifting mechanism by hoist drive sprocket with support the chain that hoists that sprocket wheel supports and link to each other with hoisting by the drive sprocket that hoists; Dolly is connected with the dolly drive sprocket by the axially movable dolly transmission mechanism that rotates in a circumferential direction, and the dolly drive sprocket is installed in by dolly drive sprocket and dolly and supports on the dolly chain of sprocket wheel support.
The present invention can also adopt following technical scheme:
Be used to drive the cart drive sprocket the cart actuating device, be used for the driving trolley drive sprocket drive car, be used to drive the hoist actuating device of drive sprocket and all be positioned at the outside of factory building.
Cart, dolly and lifting mechanism move sprocket wheel, cart drive sprocket, cart support sprocket wheel, cart chain, the driving chain wheel that hoists, the drive sprocket that hoists, hoist and support the inside that sprocket wheel, the chain that hoists, dolly transmission device, dolly driving chain wheel, dolly drive sprocket, dolly support sprocket wheel and dolly chain are installed in factory building.
Advantage and good effect that the present invention has are:
After the present invention had adopted above technical scheme, each system worked alone separately, can not disturb mutually, and this chain-drive structure is applicable to have high radiation, in the working environment of high-temperature simultaneously.The situation that need lay electric wire, cable with common hoisting crane is different; The internal environment of chain-driving hoisting crane work has no the layout of electric wire; When this has just guaranteed hoisting crane work; Can not occur because of the electric dangerous situation that causes such as aging, on fire, compare with common hoisting crane and have more safety.Because the chain-drive power system is arranged in the outside of factory building, also can be convenient to personnel's maintenance, especially adventurous radiation in factory building under the disadvantageous situation of human body, guarantees that personnel's safety is significant.

The specific embodiment
For further understanding summary of the invention of the present invention, characteristics and effect, exemplify following examples now, and conjunction with figs. describes as follows in detail:
See also Fig. 1; A kind of chain transmission crane that is used for the specific safety place; Comprise cart 1, at reciprocating dolly 18 on the cart be installed in the elevating mechanism 9 on the dolly; Cart is installed on the cart chain 6 that is supported by cart drive sprocket 4 and cart support sprocket wheel 7 by moving sprocket wheel 5; Lifting mechanism by hoist drive sprocket 14 with support the chain 13 that hoists that sprocket wheel 17 supports and link to each other with hoisting by the drive sprocket 12 that hoists; Dolly is connected with dolly drive sprocket 23 by the axially movable dolly transmission mechanism that rotates in a circumferential direction; The dolly transmission mechanism is a dolly turn-screw 24 in the present embodiment, and the dolly drive sprocket links to each other with the dolly chain 22 that is supported sprocket wheel 26 supports by dolly drive sprocket 21 and dolly.
Be used to drive the cart drive sprocket the cart actuating device, be used for the driving trolley drive sprocket drive car, be used to drive the hoist actuating device of drive sprocket and all be positioned at the outside of factory building.
Cart, dolly and lifting mechanism move sprocket wheel, cart drive sprocket, cart support sprocket wheel, cart chain, the driving chain wheel that hoists, the drive sprocket that hoists, hoist and support the inside that sprocket wheel, the chain that hoists, dolly transmission device, dolly driving chain wheel, dolly drive sprocket, dolly support sprocket wheel and dolly chain are installed in factory building.
Operating principle of the present invention is:
Work after beginning after 2 energisings of cart actuating device; Driving cart transmission shaft 3 rotates; Transmit torque to cart drive sprocket 13;, cart drive sprocket 13 will drive 15 motions of cart chain after rotating; The mobile sprocket wheel that is installed on the cart chain moves according to identical linear velocity with the cart chain; Thereby realize cart moving on track 28, driving chain wheel 14 is fixed on the coaxial side of axletree of cart.Through regulating cart tightening device 8, make the cart chain keep certain tensile force simultaneously.
