Abstract
The utility model relates to a screw lifter. A lifting running mechanism is a thread running mechanism, and is composed of a thread guide way and a screw rod propulsion disk corresponding to the thread guide way. Internal threads of the thread guide way are composed of a plurality of small wheels, and are matched with external threads of the screw rod propulsion disk. A motor is connected with the screw rod propulsion disk through a chainwheel driving mechanism to drive the screw rod propulsion disk to move from top to bottom and to further drive a carriage body of the lifter to lift. The utility model has the advantages of practicability and convenience, easy fabrication and enhanced safety and loading capacity.
Description
The utility model relates to elevator, relates in particular to the civilian elevator that adopts screw propulsion mechanism.
Common elevator, particularly civilian elevator (elevator) is that motor and control system and safety system constitute by envelope assembly, pulley lifting mechanism.Its lifting principle mainly is to utilize the power of motor to hang by the pulley lifting mechanism to rise envelope, finishes the process of the lifting of envelope.The elevator that utilizes this principle to make has many shortcomings, for example hangs with the pulley elevator and rises envelope, has wirerope to be broken and causes envelope danger out of control; And for example in the elevator use, when elevator walks to when cutting off the power supply between two floors, cause the elevator envelope can not go up again can not under situation, the passenger in this moment envelope is powerless, causes great inconvenience; For another example, the load carrying ability of this class elevator is very restricted.
The purpose of this utility model provides a kind of safe in utilization, and load carrying ability is big, adopts the elevator of screw propulsion mechanism, and it should be easy to use, and is easy to manufacture.
The purpose of this utility model is achieved in that a kind of screw thread elevator, includes frame, rack-mounted motor, and the lifting traveling gear of this elevator is the screw thread traveling gear.This screw thread traveling gear is constituted by two screw thread guide rails with cooresponding two the screw rod pushing discs of screw thread guide rail.The negative thread of screw thread guide rail is to be made of some steamboats, and matches with the outside thread of screw rod pushing disc, and the screw rod pushing disc is connected with motor by chain wheel driving mechanism, and is installed on the frame by its center shaft.
The utility model will be further described below in conjunction with accompanying drawing:
Fig. 1 is the structural representation of the utility model lifting traveling gear.
According to Fig. 1, envelope (1) is installed on the frame (2), motor (3) is installed in the centre of frame (2), and by rotating shaft (4) standing screw pushing disc (5), screw thread guide rail (7) is 2 on the both sides of frame (2), be installed in the hoistway both sides, cooresponding with it screw rod pushing disc (5) also has 2, is installed in the both sides of frame, and the negative thread (6) on the screw thread guide rail (7) is to be made of some steamboats, these steamboats are garden platform shape, and they match with outside thread on the screw rod pushing disc (5).Sprocket wheel (8) is installed on the output shaft of motor (3), is connected with sprocket wheel (10) on being fixed on rotating shaft (4) by messenger chain (9).Have emergent window (12) below on the base plate of elevator envelope (1), a manual turntable (11) that joins with chain wheel driving mechanism is arranged below emergent window.
Course of action of the present utility model is such, when motor (3) rotates, by by sprocket wheel (8), the chain wheel driving mechanism drive screw pushing disc (5) that messenger chain (9) and sprocket wheel (10) constitute rotates, the outside thread of screw rod pushing disc (5) matches with the negative thread (6) of screw thread guide rail (7), make screw rod pushing disc (5) do dipping and heaving, thereby drive whole envelope (1) lifting.Unforeseen circumstances appears when time between envelope place two place's floors, motor (3) stall, people in envelope (1) can open emergent window (12), rotation manual rotating disk (11), thereby driving screw rod pushing disc (5) by chain wheel driving mechanism rotates, make envelope (1) drop to next floor, the people's safety in the envelope (1) is left.
The utility model has adopted the principle of spiral lift, compare with common elevator, safety increases greatly, charge capacity also improves greatly, owing to adopt two screw rod pushing discs, makes processing and fabricating become easy, adopt steamboat to make the screw-internal thread fit of outside thread and screw thread guide rail, make the cliding friction of screw thread become friction of rolling, reduced noise and power of motor, use the more convenient practicality that seems.
Claims (4)
1. spiral lift, include frame, rack-mounted motor, the lifting traveling gear that it is characterized in that this elevator is the screw thread traveling gear, this screw thread traveling gear is constituted by the screw thread guide rail with the corresponding screw rod pushing disc of screw thread guide rail, and the negative thread of screw thread guide rail is made of some steamboats, and matches with the outside thread of screw rod pushing disc, the screw rod pushing disc is connected with motor by chain wheel driving mechanism, and is installed on the frame by rotating shaft.
2. spiral lift according to claim 1 is characterized in that the screw thread guide rail is 2, is distributed in the both sides of hoistway, and cooresponding with it screw rod pushing disc also has 2, is installed in the both sides of frame.
3. spiral lift according to claim 1, the steamboat that it is characterized in that constituting negative thread is a garden platform shape steamboat.
4. spiral lift according to claim 1 is characterized in that having on the base plate of elevator envelope an emergent window, below emergent window a manual turntable that is connected with chain wheel driving mechanism is arranged.
