In order to increase the storage capacity of a warehouse, a stereoscopic warehouse is used for storing goods. The elevator is one of important equipment in stereoscopic warehouse or intelligent warehouse. The goods or the carrier can be carried on a plurality of storage layers by using the elevator. For example, a truck carrying goods on the ground, in particular a shuttle truck, can be lifted by a lift onto a three-dimensional shelf.

In the prior art, shuttle trucks are typically lifted by lifts with a cargo platform. That is, the shuttle car carrying the goods is driven into the bottom surface of the cargo bed of the hoist from the ground, then lifted to the corresponding layer of the three-dimensional shelf, and the shuttle car carrying the goods is driven out from the bottom surface of the cargo bed, and then enters the running rail or the running bottom surface to perform the operation. The existing elevator adopts a cable to lift or four upright post supporting structures, and because the thickness of the cargo carrying platform is larger, a steel platform or a docking mechanism of the embedded hydraulic elevator is often required to be arranged, so that the storage cost in the cargo storage process is increased, and the maintenance cost of equipment is also increased.

Figure 1 is a schematic view of the structure of a hoist car of a hoist in accordance with an embodiment of the present utility model at the bottom of a support frame,

as shown in fig. 1, each side support frame of the elevator includes 2 columns 111, a lifting car 210, and a counterweight. Wherein, each stand 111 is vertically arranged, and a plurality of stand 111 at one side are combined into a square frame. The lifting car 210 is driven by a lifting motor to move up and down along the plurality of upright posts 111. The lifting car comprises a left car wall, a right car wall, a top beam positioned at the top and having two ends respectively connected to the left and right car walls, a load carrier 220, and a drive mechanism. The bottom of the lifting car 210 has an opening 211 extending in the front-rear direction. The load bed 220 includes two spaced apart support rails 221 extending longitudinally in a symmetrical arrangement toward one another. Two support rails 221 are provided on both sides of the opening 211, respectively. The cargo bed drive is disposed on the top beam and the walls of the lift car 210. The loading table 220 is movable in the width direction, i.e., the front-rear direction, of the lifting car 210 by the driving of the loading table driving mechanism. The counterweight part includes a counterweight 310, the counterweight 310 is connected with the lifting car, and the counterweight 310 is synchronous with and moves in reverse direction of the lifting car.

In this embodiment, the counterweight is used to balance the lift car to ensure a smooth ascent or descent of the lift car carrying the shuttle car. Referring to fig. 2 and 3, the balancing weight descends in synchronization with the ascent of the lifting car, i.e., when the lifting car descends to the lowest position of the upright 111, the balancing weight is located at the very top; when the lifting car ascends to the middle part of the upright post 111, the balancing weight correspondingly descends to the middle part of the upright post 111; and as the lift car further rises until it rises to the top of the upright 111, the counterweight gradually descends to the bottom of the upright 111. The weight is not particularly limited in structure and size, and can be set according to the weight of the lifting car or the weight of the shuttle carrier and the goods to be lifted.

Illustratively, the weight components of the elevator include two sets of weight guide components in addition to the weight 310, the two sets of weight guide components being disposed on either side of the weight 310. The balancing weight guiding component comprises a guide rail 311 and a groove sliding block 312, the guide rail 311 is vertically arranged, the guide rail 311 is fixedly connected with the square frame of the elevator, at the moment, the groove sliding block 312 is fixed on the front side wall and the rear side wall of the balancing weight 310, and the groove sliding block 312 is matched with the guide rail 311 to realize guiding in the lifting movement process of the balancing weight 310. In addition, the balancing weight 310 and the lifting car can be connected through an open chain, at the moment, a chain wheel meshed with the chain for transmission is arranged at the top of the square frame, and two ends of the chain are respectively connected with the balancing weight 310 and the lifting car. In addition, the counterweight 310 and the lifting car can be connected by a wire rope, and the chain wheel is replaced by a pulley. In addition, the two guide rails 311 positioned at the front and rear sides of the counterweight 310 can be further tensioned by a connecting beam arranged transversely, so as to improve the stability of the counterweight component.

Referring to fig. 1, the number of the vertical columns 111 of the elevator may be four, and the four vertical columns 111 enclose a rectangular parallelepiped frame. The square frame comprises four upright posts 111, top beams 112 and a plurality of cross beams 113, wherein the number of the top beams 112 is two, and the two top beams 112 are arranged in parallel. The plurality of cross beams 113 are also arranged in parallel, each cross beam 113 is arranged along the width direction of the square frame, each cross beam 113 is arranged between two upright posts 111, and two ends of each cross beam 113 are respectively connected with two adjacent upright posts 111. The width direction of the square frame refers to the X-axis direction shown in fig. 1. In this embodiment, the upright post 111, the top beam 112 and the cross beam 113 are combined to form a stable square frame, and at this time, the bottom of the square frame is further fixed on the ground, so that the connection between the square frame of the elevator and the ground is realized, and the lifting car can be stably lifted along the upright post 111.

In some embodiments of the present utility model, the lift drive mechanism includes a lift motor 410, a lift gear 421, and a vertical rack 422. The hoist motors 410 are respectively fixed to side walls of both sides of the hoist car 210, i.e., left and right car walls. Each of the vertical racks is provided on the lifting car 210, and each of the vertical racks is fixed to each of the upright posts 111.

Referring to fig. 4, the hoist motors 410 are used as driving parts, and each hoist motor 410 is provided on the left or right sidewall of the hoist car 210. At this time, the lifting motor 410 drives the lifting car to perform a lifting motion through the vertical rack. Illustratively, a lifting gear 421 and a vertical rack 422 are used in the example shown in the figures. Under the rotation driving of the lifting motor 410, the lifting gear 421 rotates in synchronization with the output end of the lifting motor 410, and a linear driving mechanism in which the rack is stationary, the gear rotates and moves is formed as the vertical rack 422 engaged with the lifting gear 421 is fixed to the upright 111. So that the lifting car climbs or descends along the vertical rack.

It will be appreciated that the lifting rack and pinion mechanism is merely an example, and that in other embodiments the vertical rack may be replaced with other mechanical mechanisms that convert the rotational motion output by the motor to linear motion, such as a lead screw nut mechanism. For example, when the vertical rack is a screw-nut mechanism, the screw may be provided on the upright 111 as a first fixing portion, and the nut may be provided on the lifting car 210 as a first linear moving portion, similar to the lifting rack-and-pinion mechanism.

Further, in order to reduce the assembly difficulty and cost of the elevator, the number of the lifting motor 410 and the number of the lifting rack and pinion transmission mechanisms are two, and the vertical racks 422 in the two lifting rack and pinion transmission mechanisms are respectively arranged on two upright posts 111 of one group of the square frames, which are diagonally arranged. Specifically, two lifting motors 410 are respectively provided on the left and right side walls of the lifting car 210, and two vertical racks 422 are respectively fixed to the two upright posts 111 at both ends of the first diagonal of the square frame. Referring to fig. 4, two vertical racks 422 are oppositely disposed, and the vertical racks 422 are disposed on sides of the upright 111 parallel to a length direction of the hoist, which refers to an X-axis direction shown in fig. 1. In this embodiment, the two sets of lifting rack and pinion gears are arranged in a diagonal manner, so that on the premise of ensuring stable lifting of the lifting car, the least number of lifting rack and pinion gears are adopted as lifting gears between the lifting motor and the lifting car, thereby reducing the assembly precision requirement, reducing the assembly cost and maintenance cost of the elevator, and further reducing the storage cost of goods storage.

It will be appreciated that, in addition to the two lifting motors 410 and two sets of vertical racks in the present embodiment, vertical racks may be mounted on the four columns 111 of the square frame, so that four sets of vertical racks are disposed between the lifting car and the square frame, and the number of corresponding lifting motors may be two or more, so that for the lifting machine with more sets of lifting gear rack driving mechanisms, stable lifting of the lifting car may be ensured, but the requirement on assembly precision of multiple vertical racks is correspondingly improved to a certain extent.

In some embodiments of the present utility model, to ensure that the load bed 220 of the lifting car is movable in the fore-and-aft, i.e., width, direction of the lifting car 210, the load bed drive mechanism includes a translation drive motor 510 and a translation gear. The translation drive motor 510 is disposed at the top beam of the lift car 210. The translation drive mechanism is located between the translation drive motor 510 and the cargo bed 220. The width direction of the lifting cage 210 is the X-axis direction shown in fig. 1; fig. 6 is a schematic view of a state in which the cargo bed 220 in the lifting car is extended, and fig. 5 is a schematic view of a state in which the cargo bed 220 in the lifting car is not extended.

Referring to fig. 5, the overall appearance of the lifting car 210 may be a rectangular parallelepiped-shaped structure with an open bottom, also commonly referred to as a gantry configuration. At this time, the front side and the rear side of the lifting car 210 are both in a through open structure, so that the shuttle carrier carrying the goods can conveniently enter or exit, the bottom of the lifting car 210 is an opening 211, and the cargo platforms 220 are arranged at two sides of the opening 211. In this embodiment, the rotational movement of the output end of the translation drive motor 510 is transmitted to the cargo bed 220 via a flexible transmission member, such as a chain or the like, that is, the flexible transmission member converts the rotational movement output by the translation drive motor 510 into a linear movement of the cargo bed 220. The translation drive motor 510 and the second linear drive mechanism are each correspondingly disposed on the lift car 210. The cargo tables 220 located at both sides of the opening 211 may be driven by the same translation driving motor 510, or may be driven by different translation driving motors 510, respectively. When driven by different translation driving motors 510, rotational synchronicity of the two translation driving motors 510 should be ensured in order to move the two support rails synchronously. In addition, in order to improve the supporting strength of the cargo platform, referring to fig. 6, a reinforcing member may be further disposed between the openings of the lifting car, and the reinforcing member is disposed at the bottom of the cargo platform, so that when the lifting car falls to the lowest position of the supporting frame, the reinforcing member at the bottom of the opening is in direct contact with the ground, and at this time, the height difference between the supporting rail and the ground is greatly reduced compared with the lifter in the prior art, which needs to resort to a docking mechanism such as a steel platform or a buried hydraulic lifter.

Further, in one embodiment, the translational drive includes a chain, a drive shaft, a translational drive gear, and a horizontal rack 521. The translation driving gear is positioned at the bottom to drive the horizontal rack. And the horizontal rack 521 is fixed to the cargo bed 220 as a straight moving portion. Referring to fig. 6 and 7, the cargo bed is mounted in a fore-and-aft laterally movable manner on left and right supports extending inwardly of the bottom of each of the left and right walls. The cargo bed 220 is provided with support rails 221, i.e., left and right support rails, for supporting the shuttle carrier. A mounting plate is provided on the cargo bed 220 parallel to the support rails 221, and a horizontal rack 521 is secured to the mounting plate. Further to guide the movement of the load bed 220, the load bed drive mechanism further comprises a guide member located between the load bed 220 and the lifting car 210. The fixing piece of the guide member is fixed to the lifting car 210 at this time, and the moving piece 531 of the guide member is fixed to the mounting plate of the cargo bed 220; thus, in this embodiment, the second linear transmission mechanism converts the rotational motion of the translation driving motor 510 into a linear motion by the rotational driving of the translation driving motor 510, and thus the cargo bed 220 is moved in the width direction of the elevator by the guiding of the guiding member.

Further, the end of the support rail 221 has a support portion 222 for supporting on a stereoscopic shelf. In this embodiment, the cargo bed 220 is provided in a movable form, and the end portions of the support rails 221 are provided with the support portions 222, so that when the shuttle carrier on the three-dimensional shelf is driven into the lift car from the three-dimensional shelf, the cargo bed 220 can be moved first to support the end portions of the cargo bed 220 on the three-dimensional shelf, and when the shuttle carrier is driven to the intermediate position of the cargo bed 220, the cargo bed 220 carrying the shuttle carrier is moved again to the position. When the shuttle carrier is driven out of the lift car, the cargo bed 220 carrying the shuttle carrier may be moved to the front end to be supported on the stereoscopic shelf, and the shuttle carrier may be further driven out of the lift car. In this embodiment, in the initial stage of the shuttle carrier entering the cargo table 220 or in the later stage of the shuttle carrier exiting the cargo table 220, the tilting phenomenon of the cargo table 220 caused by a larger load difference between the front end and the rear end of the cargo table 220 is avoided, and the uneven stress phenomenon of the cargo table 220 is alleviated.

Further, the cargo table driving mechanism further includes a flexible transmission member 231 and a transmission shaft 232, the translational driving motor 510 is fixed at the top position of the lifting car 210, the transmission shaft 232 is disposed along the length direction of the lifting car 210, the number of the second linear transmission mechanisms is two, and the transmission shaft 232 and each second linear transmission mechanism are all driven by the flexible transmission member 231, and the flexible transmission member may be a chain. Referring to fig. 5, the two supporting rails 221 are driven by the same motor, at this time, the translation driving motor 510 is fixed at the top of the lifting car 210, and is specifically located on the left side wall of the lifting car 210, two ends of the transmission shaft 232 are further connected with the left and right side walls of the lifting car 210, at this time, a chain transmission, a belt transmission or a gear transmission mechanism may be disposed between the output shaft of the translation driving motor 510 and the transmission shaft 232, that is, the translation driving motor 510 drives the transmission shaft 232 to rotate through a mechanical transmission mechanism. Since the transmission shaft 232 spans the length direction of the lifting car 210, and since the two support rails 221 are respectively located at two sides of the opening 211 at the bottom of the lifting car 210, mechanical transmission mechanisms are respectively disposed between two ends of the transmission shaft 232 and the cargo platforms 220 located at two sides of the opening 211, so that synchronous movement of the cargo platforms located at two sides of the opening is achieved by driving the same translation driving motor 510. Specifically, two driving sprockets are symmetrically arranged at two ends of the transmission shaft 232, and two driven sprockets are respectively and correspondingly arranged on the bottom wall of the carriage body, so that the transmission chain is meshed with the driving sprocket and the driven sprocket, and then the rotary motion of the transmission shaft 232 can drive the cargo carrying platform 220 to move along the width direction of the carriage body through the flexible transmission piece 231 and the second linear transmission mechanism.

It should be appreciated that it is only a preferred embodiment to simultaneously drive the two cargo tables 220 by one translation drive motor 510. Illustratively, in another embodiment, the table drive mechanism has two translation drive motors 510, where the table drive mechanism of this embodiment includes only two translation drive motors 510, two sets of guide members, and two sets of second linear drives. And two translation driving motors 510 are respectively disposed at two sides of the bottom opening 211 of the carriage body, each translation driving motor 510 is connected with the corresponding cargo carrying platform 220 through the second linear transmission mechanism, and at this time, since the two cargo carrying platforms 220 are driven by different motors, there is no need to dispose a transmission shaft 232 and other mechanical transmission mechanisms between the transmission shaft 232 and the second linear transmission mechanism.
