Abstract

The utility model relates to an elevator type four-hanging-point traction device for a parking garage, which is composed of a motor, coupling shafts, shaft couplers, a traction machine and traction wheels, wherein the motor is a motor with two outlet shafts, the coupling shafts are installed on both ends of the motor, the other end of each coupling shaft is driven and connected with the traction machine, the number of the shaft couplers is four which is divided into two groups, the shaft couplers are respectively installed on the output end of the traction machine, and a traction wheel is installed on the other end of each shaft coupler. Wire ropes surround the traction wheels, one end of each wire rope is connected with a cage, and the other end of each wire rope is connected with a counterweight frame used for balancing. The four traction wheels form the four hanging points. Thereby, traction is simultaneously carried out on the cage which does fast smooth up and down movement, with good synchronization.

Description

Elevator type parking garage four-point lifting drag device

The utility model relates to the mechanical automation parking systems, the four-point lifting drag device in the high-rise garage parking of particularly a kind of Elevator.

Suspension centre in the middle of existing passenger lift and freight elevator generally have only, carrying capacity is less, and tilting complex torque is bigger, though lifting actuator is simple and easy to control, applies to lifting and carries automobile then infeasible.

The purpose of this utility model provides a kind of elevator type parking garage four-point lifting drag device, and it can draw and take advantage of the car that carries automobile to do the elevating movement of quick and stable, and operation is smooth, and synchronism is good.

A kind of elevator type parking garage four-point lifting drag device described in the utility model comprises motor, coupling spindle, shaft coupling, traction machine and pull rope; Described motor is the two shaft motor that can do forward and reverse rotation, is installed in the center of fixed frame; Described coupling spindle is a major axis, is provided with two, is installed in two ends of two shaft motor respectively; Described traction machine comprises and is respectively left-handed and worm gear and worm screw dextrorotation, and traction machine is provided with two, and the other end with two major axis is in transmission connection respectively; Described shaft coupling has four, forms one group for every adjacent two, and every group of shaft coupling is connected to two outputs of every traction machine, at the other end of each shaft coupling a traction sheave is housed respectively; Described traction sheave is by bearing block support, and implements braking by being installed in the other brake of side; On traction sheave, an end of per share wire rope is connected with car as the wire line thimble of pull rope, the other end of wire rope with can be connected as the counterweight frame that balance is used, four traction sheaves constitute four suspension centres, thus car are carried out the lifting traction simultaneously.

The utility model is novel, and structure letter refining can be drawn and be taken advantage of the car that carries automobile to do the elevating movement of quick and stable, and carrying capacity is bigger, has overcome the big shortcoming of tilting complex torque, and it moves smooth, and synchronism is good, is convenient to manufacturing, installation and maintenance.

Below in conjunction with accompanying drawing the utility model is elaborated.

Fig. 1 is a kind of vertical view of elevator type parking garage four-point lifting drag device.

Fig. 2 is the elevation of above-mentioned four-point lifting drag device.

Referring to Fig. 1 and Fig. 2, a kind of elevator type parking garage four-point lifting drag device comprises motor, coupling spindle, shaft coupling, traction machine and pull rope.

Motor is an a kind of pair of shaft motor 1, can do forward and reverse rotation, and it is installed in the center of fixed frame 2.

Coupling spindle is a major axis 3, is provided with two, is installed in two ends of two shaft motor 1 respectively, is symmetrical arranged mutually.

Traction machine 4 comprises and is respectively left-handed and worm gear and worm screw dextrorotation.Traction machine 4 is provided with two, and the other end with two major axis 3 is in transmission connection respectively, also for being symmetrical arranged mutually.

Shaft coupling 5 has four, one group of every two adjacent composition, and every group of shaft coupling 5 is connected to two outputs of every traction machine 4, just connects two one group shaft coupling 5 at two outputs of every traction machine 4.The other end at each shaft coupling 5 is equipped with a traction sheave 6 respectively, and what promptly be connected with shaft coupling 5 has two groups to amount to four traction sheaves 6, forms four jiaos of towing points of rectangle.

Traction sheave 6 is supported by bearing support 7, and implements braking by being installed in the other brake of side 8.Brake 8 is provided with two, is a kind of dual fail-safe safety catch.Wire rope 9 as pull rope is looped around on the traction sheave 6, and an end of per share wire rope 9 is connected with car, the other end of wire rope 9 with can be connected as the counterweight frame 11 that balance is used.Four traction sheaves 6 constitute four suspension centres, and car 10 is carried out the lifting traction simultaneously.

Car 10 is equipped with puts car lift platform 12, puts the 12 interior settings of car lift platform and movably puts hull 13, puts hull 13 and can carry automobile lifting and discrepancy parking position.

Be equipped with two at the top drooping section of two same distance of wire rope 9 and make the directed sagging and guiding pinch roller 14 of traction of wire rope 9.Guiding pinch roller 14 is one group by two, amounts to four groups eight, will be looped around wire rope 9 guide and limits on the traction sheave 6 respectively and is compressed, and guiding pinch roller 14 can be regulated.

The course of work of the present utility model is as follows: two shaft motor drive two traction machine rotations by two coupling spindles, have connected two groups of totally four traction sheaves on the slow-speed shaft of two traction machine two ends.The worm and gear of two traction machines is respectively left-handed and dextrorotation, therefore two groups of traction sheaves turn to just in time opposite, make and be looped around two groups of four strand rope ropes on the traction sheave respectively to do two strands by one group the equidirectional operation, thereby guarantee when motor just changes, rope traction car on four traction sheaves moves to up direction, during the motor counter-rotating, car then moves to down direction.Because two traction machines are provided with brake respectively, when motor power was cut off, two brakes moved simultaneously by mechanical device, and two traction machines are braked simultaneously, and braking accurately, has reliably been guaranteed the utility model safety and operation reliably.
