Technical field
The present invention relates to elevators fields, i.e. the door-opening mechanism simulator of Miniature stair control Practical training equipment.
Background technique
In the prior art, it teaches in instrument industry and emerges one after another for the Practical training equipment of professional and technical training, elevator real training is set
Standby is also multifarious.Existing elevator Practical training equipment mainly has four classes: 1. large-scale elevator model Practical training equipments；2. large size simulation
Elevator Practical training equipment；3. microsimulation elevator Practical training equipment；4. Miniature stair logic Practical training equipment.
Large-scale elevator model Practical training equipment is that elevator used in life is object, and door-opening mechanism is the synchronization really used
Tape handler transmission, so that elevator door be driven to carry out switch motion.
Large-scale simulant elevator Practical training equipment is Model Elevator equipment, is designed using similar elevator running, 6 layers of elevator are generally high
Degree is 2.5m or so, and door-opening mechanism also uses the synchronous belt drive mechanism of class elevator model to add some auxiliary bodies, such as lever
The composition such as mechanism, toothed belt transmission drive door to be switched.
Microsimulation elevator Practical training equipment it is more be that design size is smaller, may be generally disposed at desktop, design structure phase
To simple, the elemental motion of achievable elevator, elevator up-down and switch gate movement, the door-opening mechanism used mostly use cunning
Set mechanism, nylon rope pull elevator door to be acted.
Microsimulation elevator Practical training equipment only carries out uplink and downlink and acts without switch gate, and switch gate is acted by logic state
Indicator light substitution is completed.
Miniature stair logic Practical training equipment is opened as the logic state that its major function is in simulant elevator control process
It closes the door no mechanical mechanism, only use state indicator light and button analog switch door process and limit signal.
The microsimulation elevator Practical training equipment of existing production firm is since its is small in size, the simple reason of design structure, In
It is driven when designing door-opening mechanism using pulley block mechanism, disadvantage are as follows: 1. operations will lead to rope wear, and maintenance rate is high；
2. narrow space causes rope maintenance work to be not easy to carry out；Cause switch gate normal complete 3. often will appear rope slipping
At.
The main reason for causing pulley blocks door-opening mechanism disadvantage be pulley blocks transmitting power must using softer steel wire or
The rope of person's high intensity, since wirerope in shorter size have a greatly reduced quality and can not be competent at by its flexibility, although using height
The nylon rope of intensity often rubs against to substitute but since nylon rope tensile strength is very high but not wear-resisting and inevitably results in rope damage
It is bad；Since the preferable coefficient of friction of the smoothness of nylon rope itself is low, be limited to space it is limited using thinner nylon rope cause around
The frictional force of line machine it is smaller so as to cause can not normal coiling so that system can not normal switch door.
The disadvantage is that: 1. operations will lead to rope wear, and maintenance rate is high；2. narrow space causes rope maintenance work inconvenient
In progress；Cause switch gate that can not normally complete the movement of normal switch door 3. often will appear rope slipping, reliability is low.It improves
The reliability of system and less maintenance time and cost.
Summary of the invention
The purpose of the present invention is provide a kind of door-opening mechanism mould of Miniature stair control Practical training equipment in view of the above deficiencies
Quasi- device.Solve the door-opened elevator slippage problems in microsimulation elevator Practical training equipment.
The technical solution of the invention is as follows: Miniature stair controls the door-opening mechanism simulator of Practical training equipment, including electricity
Terraced carriage, lift car have elevator door, it is characterised in that are equipped with motor-driven gear, corresponding elevator in lift car top surface
Door upper end is fixed with the rack gear engaged with gear 7, and elevator door lower end is sat on the slide rail.
In above scheme,
It is connected in upper end by sliding slot between elevator door and lift car.
Sliding slot is dovetail groove.
Special-shaped sliding rail is I-steel shape.
Power is transmitted using the transmission mechanism of rack-and-pinion, and using cooperating special-shaped rail structure with high accuracy to be oriented to, is made
Door-opening mechanism it is small in size, compact-sized, securely and reliably, durability is good, and daily maintenance only needs that a little lubricating oil is added, gram
Open the door in existing mechanism skidding, disadvantage difficult in maintenance, maintenance efficiency is low have been taken, while has obtained system reliability effectively
Improve, switch gate movement can be completed accurately.Due to using special construction sliding rail conducting wire, so that the dress that system is assembled in small space
Assembly difficulty with difficulty compared to pulley blocks machine mechanism reduces, and production and maintenance efficiency can be improved, substantially increase simultaneously
The reliability of system entirety.The present invention uses wear-resisting metal material, and longtime running also only generates the abrasion of very little, will not
Badly damaged problem is caused, the maintenance rate of mechanism is greatly reduced.
Special-shaped 4 sliding slot matching mechanism of sliding rail, whole device will be unable to complete limitation elevator without special-shaped sliding rail slide way mechanism
Door is run in unique straight line direction, while also ensuring the elevator door not side due to transformation of the position of engagement of rack-and-pinion
It turns over.
The invention has the advantages that 1. existing microsimulation elevator Practical training equipment door-opening mechanisms using organic glass material or its
The reel folding and unfolding nylon rope of his material generates pulling force to drive elevator door to move, to obtain bigger frictional force coiling wheel surface
Anti-skid chequer can have been designed and used biggish tensile force, thus increase frictional force but will lead to rope wear aggravation simultaneously, for a long time
Operation will lead to rope wear fracture and can not normal use, make since device structure is compact replace nylon rope become very not side
Just；The present invention is constituted using rack-and-pinion and special-shaped sliding rail etc., in structure and transmission principle with existing microsimulation elevator
Practical training equipment door-opening mechanism is entirely different, and rack-and-pinion, special-shaped sliding rail etc. are all made of metal material of the intensity compared with high wear resistance, more
Add sturdy and durable wear-resistant.The engagement of rack-and-pinion and special-shaped sliding rail and special-shaped sliding slot maintenance are very convenient, and when maintenance is added
A little lubricating oil can be accomplished not needing replacement main component in the life cycle of whole equipment substantially.
2. existing microsimulation elevator Practical training equipment door-opening mechanism is driven using pulley blocks, in the device of narrow space
Winding nylon wire operates inconvenient and to control the elastic appropriateness of nylon rope simultaneously even more extremely difficult, is unfavorable for large quantities of
Scheduling and planning is measured, and increases cost of labor for the after-sale service in later period；The present invention is being pacified using the transmission mechanism of rack-and-pinion
Adjustment only needs to guarantee rack-and-pinion positive engagement when trying, and what it is due to the use of entire mechanism is hard material, during installation
The special-shaped slot and the special-shaped sliding rail of carriage for guaranteeing elevator door are worked good, and by the top of elevator door DC speed-reducing and bracket press
It is installed according to screw hole, may make that assembling process is not substantially assorted according to the assembly of correct assemble sequence during the installation process
Difficulty, alleviates the maintenance difficulties in later period, and when production is even more whole as a portion after being installed entire mechanism
Part installation does not influence other process assembly completely, is conducive to batch production debugging.
3. existing microsimulation elevator Practical training equipment door-opening mechanism using pulley blocks be driven, when nylon rope tension adjustment not
It often will appear rope slipping when suitable to lead to not normally complete the movement of normal switch door, this point is in any pulley drive system
It is likely to occur in system, occurs being relatively conventional in microsimulation elevator Practical training equipment door-opening mechanism, the reason is that entirely
Organization volume is small, and the nylon rope not being available compared with thick (contact area is big, and frictional force is bigger at the same pressure) transmits power；
The present invention is completely absent the problem using rack-and-pinion transmitting power, and what rack pinion relied on is the pressure between tooth and tooth
Power transmission necessarily will drive elevator door movement when motor rotation as long as installation would not reliably there are problems that skidding,
The problem of being not in operation not in place or malfunction.
4. existing microsimulation elevator Practical training equipment door-opening mechanism elevator door limits elevator using two parallel optical axises
Door slides in the direction of needs, due to especially to guarantee the parallel right and wrong of two optical axises in the device of narrow space in installation and debugging
Often difficult, the installation of two axis will lead to switch gate resistance when not parallel big, will lead to elevator door when serious and is stuck and is unable to complete
Movement, the frictional force already mentioned before for pulling elevator motion to need reel, when switch gate resistance is big, reel is bound to
Bigger frictional force is needed to drive nylon wire folding and unfolding, to result in nylon rope abrasion aggravation indirectly, skidding leads to switch gate
Movement cannot normally complete；The present invention is oriented to using special-shaped sliding rail and special-shaped slide way mechanism can guarantee that elevator door can only be
The direction operation needed, only needs to guarantee abnormity sliding rail installation level when installing special-shaped sliding rail, installation and debugging difficulty compared with
It is lower in double parallel sliding rail, reduce debugging and later maintenance difficulty.
