The specific embodiment
A kind of access lock transmission case based on the sheave transmission as shown in Fig. 1～Figure 15, mainly be comprised of component such as box assembly 1, box-staple wheel assembly 2, main drive shaft assembly 3, the sheave assembly 4 that opens the door, link arm assembly 5, equalizing valve opening assembly 6, driving gear component 7, balance interlock slot wheel assembly 8, interlocking assembly 9, hand wheel shaft assemblies 10.
Box assembly 1 is the lead frame structure, mainly by gripper shoe, median septum, front panel, side plate, base plate, top board and upper and lower sides cover plate, formed, wherein except front panel and upper and lower sides cover plate be bolted, all the other are all by being welded to form an integral body, and the bolt of front panel is connected with the installation that is beneficial to the box house assembly and the integral body processing of casing.The upper and lower sides cover plate does not play the casing supporting role, can often dismantle, and is convenient to observe and Installation and Debugging.
Box-staple wheel assembly 2 and the sheave assembly 4 that opens the door have identical 26S Proteasome Structure and Function, by Geneva mechanism intermittent movement characteristics, realize the intermittent movement of door lock and hermatic door.When main drive shaft 3 drives 2 motion of box-staple wheel assemblies, the sheave of the sheave assembly 4 that opens the door and the actuating arm of main drive shaft 3 are in the locking arc state that contacts, and the sheave that now opens the door is in positioning states, and hermatic door can not rotate; In like manner, when main drive shaft drives while opening the door the motion of sheave assembly, the sheave of box-staple wheel assembly 4 and main actuating arm are in the locking arc state that contacts, and now, the door lock sheave, in positioning states, can not rotate.
Be equipped with actuating arm 22, balance interlock slot wheel driving swing arm 20 and the travelling gear 21 of driving gate locked groove wheel and the sheave that opens the door on main drive shaft assembly 3, a poor state in certain angle between each sheave actuating arm, simultaneously independent of one another, when main drive shaft 25 rotates, balance interlock slot wheel driving swing arm 20, door lock sheave and the sheave actuating arm 22 that opens the door successively are with successively dynamic equilibrium interlock slot wheel 28, door lock sheave and open the door between 12 3 groups of sheaves of sheave, only having one group of sheave a time period is in rotary state, and all the other two groups in stopping positioning states.
Equalizing valve opening assembly 6 one ends connect balance interlock slot wheel assembly 8, and the other end connects equalizing valve, completes the opening and closing function to equalizing valve.
Driving gear component 7 has the secondary gear transmission, by the secondary gear transmission, can make operated by handwheel moment reduce, and facilitates manually-operated, the angular velocity while simultaneously lowering switch gate.
Transmission case is installed two handwheels, top handwheel and bottom handwheel, and the top handwheel is responsible for the nearside hermatic door, and the bottom handwheel is responsible for the realization of distally hermatic door correlation function.
On transmission case cooperation access lock, other drive disk assembly, can carry out omnibearing feature operation to whole access lock.The top handwheel can be operated the nearside hermatic door, and the bottom handwheel can be operated the distally hermatic door by power transmission shaft.
While opening the door, operating personnel operate transmission case top handwheel, rotate driving gear component 7, driving gear component 7 drives the balance interlocking actuating arm 20 on main drive shaft assembly 3,20 band dynamic equilibrium interlock slot wheel 28 motions of balance interlocking actuating arm, at first balance interlocking sheave 28 drives interlocking assembly 9 and completes the interlocking action, then completes the unlatching of equalizing valve with acting balancing valve opening assembly 6.Equalizing valve is opened complete, and balance interlocking sheave 28 is now in stopping positioning states.Main drive shaft assembly 3 is rotated further, box-staple wheel driving swing arm 22 on it drives door lock sheave 12 and rotates, complete the door lock breakdown action, after the door lock open function is complete, door lock sheave 12 is in stopping positioning states, the sheave actuating arm 22 that opens the door on main drive shaft assembly 3 drives the sheave 12 that opens the door again, completes the breakdown action of hermatic door, so far completes whole actions of the unlatching of whole access lock hermatic door.
When the access lock hermatic door is closed when opening action just in time fully contrary.At first the sheave actuating arm 22 that opens the door on main drive shaft assembly 3 drives the sheave 12 that opens the door, complete closing of hermatic door, hermatic door is closed back pullout (BPO) sheave 12 in stopping positioning states, main drive shaft assembly 3 is rotated further, box-staple wheel driving swing arm 22 on it drives door lock sheave 12 and rotates, complete the door lock closing motion, door lock closing back door locked groove wheel 12 is in stopping positioning states, main drive shaft assembly 3 is rotated further, balance interlocking sheave 28 completes the closing motion of equalizing valve with acting balancing valve opening assembly 6, finally drive interlocking assembly 9 and complete the release action.
The bottom handwheel is operated and can complete distally hermatic door opening and closing, by power transmission shaft and chain, drive the transmission case operation in distally, complete the operation to the distally hermatic door.Athletic performance and top handwheel are identical.
Under particular case, if need to remove interlocking, can open the minor flaps on box side, complete the dismounting to interlock, can remove interlocking, meet instructions for use.
