Abstract
The utility model provides the utility model discloses an engagement type elevator of lead screw, it is passed through its characterized in that belt (2) and is driven the rotation of lead screw I by motor (1), motor to to drive lead screw II rotatory through driving reversing gear (3), and lead screw I and lead screw II promote the sedan -chair body through silk braid (5) the meshing on rotatory and the sedan -chair body (4), and the lead screw is fixed through bearing (6) from top to bottom, above the sedan -chair body and hawser (7) continuous, it is continuous that the hawser passes through pulley (8) and counter weight (9). The lift that the sedan -chair was personally experienced sth. Part of the body is controlled through the lead screw and the meshing of silk braid to this elevator, can avoid the fracture of ordinary elevator hawser to lead to the elevator to drop suddenly.
Description
Technical field
The utility model relates to a kind of novel elevator, and this elevator is applicable to fortune people and transports thing, belongs to elevator safety field.
Background technology
Elevator is facilitate high-rise buildings upper and lower, has but often become to take by force life killer.Why elevator can become invisible killer, and key is that the quality of elevator itself and property are to this maintenance.The elevator that current high-rise buildings uses is safer from design aspect, these elevators are all to promote and landing elevator car body with steel rope, although these steel ropes configuration intensity is except bearing car and nominal payload, also consider the size of traction: elevator also has a set of drop preventer, therefore design can avoid dropping of elevator completely.And in fact, the elevator thing had an accident that drops often occurs, reason is by two aspects, and one is that the quality of elevator own does not meet designing requirement, and two is that elevator maintenance is not good at causing cord strength to reduce and drop preventer inefficacy.Be badly in need of a kind of elevator inherently, even if the elevator that et out of order also can not cause sedan-chair body to drop suddenly.
Summary of the invention
For above-mentioned situation, for overcoming the defect of existing elevator, the purpose of this utility model is just to provide one inherently, even if safeguard unreasonable when causing elevator faults, sedan-chair body also can not drop suddenly.Can effectively solve elevator accident incidence high, the problems such as elevator safety hidden danger is large.
The technical scheme that the utility model solves is rotated by belt drive screw mandrel I by electrical motor, and by driving reversing gear to drive screw mandrel II to rotate, screw mandrel I and screw mandrel II promotes sedan-chair body by the silk braid engagement on rotation and sedan-chair body, screw mandrel is fixed down through bearing, be connected with hawser above sedan-chair body, hawser is connected with counterweight by pulley.The utility model drives belt to drive screw mandrel to rotate by electrical motor, and the silk braid on the screw mandrel of rotation and sedan-chair body is meshed the lifting controlling sedan-chair body, can realize steady lifting and the landing of sedan-chair body, avoids sedan-chair body to jump bust; Be connected with counterweight by hawser above sedan-chair body, elevator counterweight is commonly called as counterbalanced weight, and elevator car body and counterweight symmetry hang on pulley.When sedan-chair body semi-load, the weight of sedan-chair body and counterweight is substantially equal, now only needs overcome friction to do work and just can drive elevator, can alleviate screw mandrel engaged elevation power.
The utility model is applied to high-rise buildings fortune people cargo transport.
The utility model adopts said structure, namely adopt screw mandrel to engage with silk braid and promote sedan-chair body, adopt counterweight to balance the weight of sedan-chair body semi-load, when can avoid Lift out of order, sedan-chair body drops, even if the elevator that has an accident also can not be able to drop because screw mandrel and silk braid engagement are stuck in the air.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is silk braid section of structure.
Detailed description of the invention
Be described in detail below in conjunction with drawings and Examples.
As shown in Figure 1, the utility model is rotated by belt drive screw mandrel I by electrical motor, and by driving reversing gear to drive screw mandrel II to rotate, screw mandrel I and screw mandrel II promotes sedan-chair body by the silk braid engagement on rotation and sedan-chair body, screw mandrel is fixed down through bearing, be connected with hawser above sedan-chair body, hawser is connected with counterweight by pulley.When sedan-chair body rises, electrical motor drives screw mandrel to rotate to sedan-chair body direction, and under the condition that screw mandrel and silk braid engage, sedan-chair body upwards climbs along screw mandrel, and sedan-chair body decreases the hoisting force of screw mandrel engagement under the traction of counterweight simultaneously, therefore can save the consumption of electric energy.When Lift out of order, the weight due to counterweight balance when sedan-chair body and semi-load thereof, sedan-chair body also can not slide down along with screw mandrel, more there will not be situation about dropping suddenly.When sedan-chair body declines, electrical motor drives screw mandrel to rotate in the opposite direction to sedan-chair body side, and under the condition that screw mandrel and silk braid engage, sedan-chair body moves downward along screw mandrel.
Claims (4)
1. the engagement type cage lifter of novel screw mandrel, it is characterized in that driving screw mandrel I to rotate by electrical motor (1) by belt (2), and by driving reversing gear (3) to drive screw mandrel II to rotate, screw mandrel I and screw mandrel II promotes sedan-chair body by silk braid (5) engagement on rotation and sedan-chair body (4), screw mandrel is fixed down through bearing (6), be connected with hawser (7) above sedan-chair body, hawser is connected with counterweight (9) by pulley (8).
2. the engagement type cage lifter of screw mandrel according to claim 1, is characterized in that it engages by screw mandrel and silk braid the lifting controlling sedan-chair body.
3. the engagement type cage lifter of screw mandrel according to claim 1, is characterized in that it can realize steady lifting and the landing of sedan-chair body, avoids sedan-chair body to jump bust.
4. the engagement type cage lifter of screw mandrel according to claim 1, it is characterized in that being connected with counterweight by hawser above sedan-chair body, counterweight can balance the weight of sedan-chair body, alleviates screw mandrel engaged elevation power.
