Description

Technical Field

[0001] The utility model belongs to the technical field of shuttle vehicles, in particular to a stopping device of a shuttle vehicle hoist. Background Art

[0002] At present, the main method used in logistics warehousing systems is that shuttle cars automatically run on guide rails and then transport goods to corresponding shelves. When the shuttle car moves to the end of the track, it will enter the lifting track and be lifted by the lifting equipment to enter another track to continue transportation.

[0003] For example, the Chinese patent of prior art 201922253742.6 discloses a mobile hoist for a shuttle car stereo warehouse. The movement of the frame is driven by a driving mechanism. The entire hoist is moved to different positions in the warehouse by horizontally moving the frame, and the cargo platform is moved to different levels by a chain mechanism. The shuttle car is moved by a bidirectional telescopic fork to achieve outbound or inbound storage, thereby improving work efficiency.

[0004] The applicant discovered that when the shuttle car docks with a certain layer of the shelf, it cannot be completely aligned with the shelf track in that layer. At this time, no matter whether the shuttle car is sent from that layer to the elevator or the elevator sends the shuttle car to that layer, there is an unexpected situation that the transfer cannot be completed smoothly, thereby affecting the working efficiency of the layer-changing elevator; in addition, in the process of the shelf transferring the shuttle car to the elevator for layer change, the shuttle car may accidentally run out of the elevator, causing it to fall to the ground and be damaged. Utility Model Content

[0005] In view of this, the purpose of the utility model is to provide a stop device for a shuttle car elevator, which has a simple structure and can ensure the smooth docking between the shuttle car and a certain layer of the shelf track, and can prevent the shuttle car from accidentally running out of the elevator.

[0006] To achieve the above purpose, the utility model adopts the following contents:

[0007] The utility model provides a stopping device for a shuttle car hoist, which comprises:

[0008] It includes a carrier substrate, two vertical support side plates are symmetrically arranged on the top surface of the carrier substrate and are parallel to each other, a horizontal lifting plate is arranged above the carrier substrate, the bottom end of the lifting plate is connected to the carrier substrate through a plurality of guide pillars and guide sleeves, and a stopper is arranged outwardly on one side of the lifting plate through a mounting frame;

[0009] On both sides of the top surface of the supporting side plate, two mutually consistent sliding slopes are arranged inward. Rollers are placed in the sliding slopes in a rolling manner. The rollers are in rolling contact with the bottom surface of the lifting plate. The four rollers are rotatably arranged on a displacement plate. The displacement plate is located between the two supporting side plates. A driving cylinder is arranged on the surface of the bearing substrate. The output end of the driving cylinder is connected to the bottom end of the displacement plate. The displacement plate is controlled to move horizontally relative to the bearing substrate through the driving cylinder.

[0010] According to a stop device for a shuttle car elevator provided by the present invention, the stopper includes a blocking seat arranged on the top surface of the mounting frame. Two articulated side frames are symmetrically arranged on the top surface of the blocking seat. A swing arm is articulated between the two articulated side frames. A vertical blocking cylinder is arranged at the bottom end of the blocking seat. The output end of the blocking cylinder penetrates upward through the blocking seat and is articulated to one end of the swing arm. In this way, the swing arm is controlled to swing up and down through the blocking cylinder, so that the end of the swing arm tilts up or falls, thereby realizing the blocking effect on the shuttle car.

[0011] Further, a rotatable buffer wheel is arranged at the end of the swing arm. In this way, the impact force of the shuttle car is absorbed by the buffer wheel, so that it stops stably slowly and avoids accidents.

[0012] According to a stop device for a shuttle car elevator provided by the present invention, a slide rail is arranged along the length direction in the middle of the bottom end of the lifting plate. A slider is slidably installed in the slide rail in a clamping manner. The slider is connected downward to the top end of the displacement plate. In this way, when the driving cylinder controls the displacement plate to move back and forth, the horizontal back-and-forth movement of the displacement plate is realized by means of the cooperation of the slide rail and the slider.

[0013] According to a stop device for a shuttle car elevator provided by the present invention, the main body part of the driving cylinder is connected to the bearing substrate through a hinge seat. The output end of the driving cylinder is connected to the bottom end of the displacement plate through a hinge joint. The stability of the driving cylinder and its ability to adapt to the rotation angle are improved through the hinge seat and the hinge joint.

[0014] According to a stop device for a shuttle car elevator provided by the present invention, a roller chute for the rollers to roll is recessed inward at the bottom end of the lifting plate. The precise guiding function of the rollers is realized through the roller chute to guide the rollers to move along a specific track and ensure the movement direction and accuracy of the rollers.

[0015] According to a stop device for a shuttle car elevator provided by the present invention, raised limit baffles are arranged on both sides of the top end of the lifting plate. The shuttle car can be accurately guided and kept in the correct position through the limit baffles, preventing the shuttle car from shifting on the elevator and affecting the layer-changing docking work.

[0016] The beneficial effects of the present utility model are as follows: The lifting plate can move up and down, enabling the shuttle car thereon to align with a certain layer on the shelf, ensuring that whether the shuttle car is sent into the elevator from this layer or the elevator sends the shuttle car into this layer, the docking and transmission of the shuttle car can be successfully completed, thereby improving the working efficiency of the elevator; moreover, the mechanical limit of the shuttle car can be achieved through the stopper, effectively preventing the shuttle car from falling from the elevator.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] To more clearly illustrate the present utility model, the following further describes the present utility model in conjunction with preferred embodiments. Those skilled in the art should understand that the content specifically described below is illustrative rather than restrictive, and should not be used to limit the protection scope of the present utility model.

[0023] In the description of the present utility model, it should be noted that unless otherwise clearly defined and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0024] Please refer to Figure 1 、 Figure 2 and Figure 3 as shown. An embodiment of the present utility model provides a stop device for a shuttle car elevator, and the stop device is installed on the lifting and docking platform of the elevator. The stop device includes a horizontally positioned bearing substrate 1, and two vertically arranged support side plates 2 that are symmetrically arranged at intervals and parallel to each other along the length direction of the top surface of the bearing substrate 1. A horizontal lifting plate 3 is further arranged above the bearing substrate 1, and the lifting plate 3 can move up and down relative to the bearing substrate 1. The bottom end of the lifting plate 3 is connected to the bearing substrate 1 through a plurality of guide post and guide sleeve groups 31, that is, the guide sleeves are vertically installed on the bearing substrate, and the guide posts are vertically connected to the bottom end of the lifting plate and are movably inserted into the guide sleeves. A stopper 4 is arranged outward on one side of the lifting plate 3 through a mounting bracket 41, and the topmost end of the stopper 4 protrudes from the horizontal plane where the surface of the lifting plate 3 is located.

[0025] Wherein, two mutually consistent sliding slopes 21 are arranged inwardly on both sides of the top surface of the support side plate 2, that is, the inclination of the slopes of the left and right sliding slopes is designed to be exactly the same. The sliding slopes 21 are hidden inside the support side plate 2, and rollers 5 are rollingly placed inside the sliding slopes 21, that is, the rollers 5 can roll back and forth along the track of the sliding slopes 21, and the rollers 5 are also in rolling contact with the bottom surface of the lifting plate 3; these four rollers 5 are rotatably connected to both sides of a displacement plate 6 together, and the displacement plate 6 is located between the two support side plates 2. A driving cylinder 7 is arranged on the surface of the bearing substrate 1 along its length direction, and the driving cylinder 7 is also located between the two support side plates 2. The output end of the driving cylinder 7 is connected to the bottom end of the displacement plate 6. By controlling the driving cylinder 7, the displacement plate 6 moves horizontally relative to the bearing substrate 1. When the displacement plate makes a displacement movement in the horizontal direction, the rollers thereon will roll back and forth along the sliding slope track. During the movement of the rollers, the height of the rollers will change. Since the rollers always maintain rolling contact with the bottom surface of the lifting plate, the rollers will jack up the lifting plate or hold it down, thereby realizing a small up and down movement of the lifting plate relative to the bearing substrate.

[0026] In this application, the lifting plate is designed to be able to move up and down relative to the bearing substrate, and the amplitude of its lifting displacement is not large. The mechanical structure for driving the lifting plate to move up and down is not complicated, the design is simple, and the occupied space is small. This enables the shuttle car on the lifting plate to be aligned with a certain layer on the shelf, ensuring that whether the shuttle car is sent into the elevator from this layer or the elevator sends the shuttle car into this layer, the docking and transmission of the shuttle car can be successfully completed; in addition, the stopper also realizes the mechanical limit of the shuttle car, effectively preventing the shuttle car from falling from the elevator.

[0027] In this embodiment, the stopper 4 includes a stopper seat 42 disposed on the top surface of the mounting frame 41. Two articulated side frames 43 are symmetrically arranged on the top surface of the stopper seat 42. A swing arm 44 is articulated between the two articulated side frames 43. A vertical stopper cylinder 45 is disposed at the bottom end of the stopper seat 42. The output end 451 of the stopper cylinder 45 penetrates upward through the stopper seat 42 and is articulated to one end of the swing arm 44. In this way, by controlling the up and down swing of the swing arm by the stopper cylinder, the end of the swing arm can be lifted or lowered, so as to achieve the blocking effect on the shuttle car.

[0028] Wherein, a rotatable buffer wheel 46 is further disposed at the end of the swing arm 44. In this way, the impact force of the shuttle car is absorbed by the buffer wheel, so that it can stop stably slowly and avoid accidents.

[0029] In this embodiment, a slide rail 32 is disposed along the length direction in the middle of the bottom end of the lifting plate 3. A slider 61 is slidably mounted in the slide rail 32 in a clamping manner. The slider 61 is connected downward to the top end of the displacement plate 6. In this way, when the driving cylinder controls the front and back movement of the displacement plate, the horizontal front and back movement of the displacement plate is realized by means of the cooperation of the slide rail and the slider, ensuring the stability of the displacement plate movement, so that all four rollers on the displacement plate can keep rolling contact with the bottom surface of the lifting plate, so that the lifting plate moves up and down smoothly.

[0030] In this embodiment, the main body part of the driving cylinder 7 is connected to the bearing base plate 1 through a hinge seat 71, and the output end of the driving cylinder 7 is connected to the bottom end of the displacement plate 6 through a hinge joint 72. The stability of the driving cylinder and its ability to adapt to the rotation angle are improved through the hinge seat and the hinge joint.

[0031] Wherein, the bottom end of the lifting plate 3 is recessed inward to form a roller chute 33 for the roller 5 to roll. The precise guiding function of the roller is realized through the roller chute to guide the roller to move along a specific track, ensuring the movement direction and accuracy of the roller.

[0032] In this embodiment, raised limit baffles 34 are arranged along the length direction on both sides of the top end of the lifting plate 3. The limit baffles ensure that the shuttle car can be accurately guided and kept in the correct position, preventing the shuttle car from shifting on the elevator and affecting the layer-changing docking work.

[0033] Obviously, the above embodiments of the present invention are only examples for clearly explaining the present invention, rather than limiting the implementation manners of the present invention. For those of ordinary skill in the art, other different forms of changes or modifications can be made on the basis of the above description. It is impossible to list all the implementation manners here. Any obvious changes or modifications derived from the technical solutions of the present invention still fall within the protection scope of the present invention.
