Description

Technical Field

[0001] The invention relates to the technical field of shuttle car elevators, and in particular to a shuttle car layer-changing elevator for a stereoscopic warehouse. Background Art

[0002] In recent years, with the rapid development of the logistics industry, automated storage and retrieval systems have become increasingly popular due to their high storage density, high efficiency, and flexible operation. A layer-changing elevator is used to change layers for shuttle vehicles. The shuttle vehicle enters the layer-changing elevator, is then lifted to the corresponding layer, and then enters the three-dimensional warehouse. The shuttle vehicle can pick up and place goods at any layer of the warehouse. In current warehousing systems, elevators are used to lift goods to the height of shelves on each floor for loading and unloading. Existing elevators include columns and a loading platform that moves up and down along the columns to carry cargo boxes. A lifting mechanism is installed on the columns to move the loading platform up and down. Next to the loading platform, there are multiple layers of tracks for shuttle vehicles to travel on. The shuttle vehicles assist in transporting cargo boxes and picking up and placing them on the loading platform.

[0003] When the elevator is raised and lowered, the cargo and shuttles on it will shake, causing the cargo to fall off and affecting work efficiency. In addition, the elevator's loading platform cannot lift shuttles and cargo that exceed its top surface area. Therefore, we propose a shuttle-changing elevator for high-bay warehouses to solve the above-mentioned problems. Summary of the Invention

[0004] In view of the above-mentioned shortcomings of the prior art, the purpose of the present invention is to provide a shuttle car layer-changing elevator for a three-dimensional warehouse, so as to solve the problem of shaking of goods and shuttle cars in the prior art.

[0005] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a shuttle car layer-changing elevator for a three-dimensional warehouse, comprising: an elevator body, and also a cargo platform arranged on the elevator body, two telescopic plates inserted on both sides of the cargo platform, a transmission assembly arranged at the bottom of the cargo platform for opening and closing the telescopic plates, two clamping assemblies arranged on both sides of the cargo platform for clamping the cargo on the cargo platform, and two control assemblies arranged on both sides of the elevator body for controlling the clamping or release of the clamping assemblies; the clamping assembly comprises two limit support plates fixedly connected to both sides of the elevator body, a limit slide sliding in the limit support plate, a connecting rod fixedly connected to the limit slide and the cargo platform, a ninth push rod passing through the limit slide, a splint fixedly connected to the end of the ninth push rod, a slide fixedly connected to the surface of the ninth push rod, and a spring sleeved on the surface of the ninth push rod, wherein the spring is located between the limit slide and the slide rod; the control assembly comprises two guide seats fixedly connected to both sides of the elevator body, a plurality of trapezoidal seats sliding in the guide seats, and a special-shaped slider fixedly connected to one side of the telescopic plate.

[0006] Furthermore, two first strip rods are fixedly connected to both sides of the bottom of the two telescopic plates, and the first strip rods pass through the cargo platform and slide in the cargo platform.

[0007] Furthermore, the transmission assembly includes a second bar rotatably connected to the bottom of the cargo platform, two third bar bars rotatably connected to the two ends of the bottom of the second bar, a force guide rod rotatably connected to the end of the third bar, and an electric push rod fixedly connected to the bottom of the cargo platform.

[0008] Furthermore, the top of the force-guiding rod is fixedly connected to the bottom of the telescopic plate, the force-guiding rod passes through the cargo platform and slides in the cargo platform, and the output end of the electric push rod is fixedly connected to the bottom of one of the first strip rods.

[0009] Furthermore, both sides of the trapezoidal seat are fixedly connected with a cross limiting rod, the cross limiting rod passes through the guide seat, and the multiple trapezoidal seats are fixedly connected by a connecting rod.

[0010] Furthermore, the surface of the special-shaped slider fits the surface of the connecting rod, and the special-shaped slider slides on the surface of the connecting rod.

[0011] Furthermore, the surface of the sliding rod fits with the surface of the trapezoidal seat, and the sliding rod slides on the surfaces of the trapezoidal seat and the guide seat.

[0012] Furthermore, one end of the ninth push rod is fixedly connected to the limiting block, and a plurality of rollers are rotatably connected to the limiting slide.

[0013] Furthermore, the clamping plate slides on the surface of the cargo platform, and one side of the clamping plate is in contact with one side of the telescopic plate.

[0014] Compared with the prior art, the technical solution provided by the present invention has the following beneficial effects: 1. Through the cooperation of the clamping assembly and the control assembly, when the cargo platform is raised and lowered, the slide bar slides along the guide seat, so that the two clamping plates clamp the shuttle and the goods, making the movement of the goods and the shuttle more stable; when the cargo platform moves to each shelf, the trapezoidal seat supports the slide bar, so that the two clamping plates are away from the shuttle and the goods, making it easier for the shuttle to move to the shelf; Second, by setting up a transmission component, when the cargo platform moves to each layer of cargo, the electric push rod drives the two telescopic plates to open in the cargo platform, thereby expanding the loading space on the top of the cargo platform, and having the effect of lifting larger cargo and shuttle vehicles. At the same time as the two telescopic plates are opened, the special-shaped slider is driven to support the trapezoidal seat and the connecting rod, so that the trapezoidal seat moves in the guide seat, which has the effect of increasing the force of the splint away from the shuttle vehicle and cargo.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0019] The present invention will be further described in detail below with reference to the embodiments.

[0020] Example 1, refer to the attached Figure 1-8 As shown, in order to solve the problem of shaking of goods and shuttles in the prior art, the present invention discloses a shuttle-changing elevator for a three-dimensional warehouse, comprising: an elevator body 1, a cargo platform 2 provided on the elevator body 1, two telescopic plates 3 inserted on both sides of the cargo platform 2, the telescopic plates 3 movably inserted into the cargo platform 2, and the telescopic plates 3 have the effect of expanding the bearing area of ​​the cargo platform 2, a transmission assembly 7 provided at the bottom of the cargo platform 2 for opening and closing the telescopic plates 3, and the transmission assembly 7 controls the opening and closing of the telescopic plates 3 to expand or restore the surface area of ​​the cargo platform 2; Among them, two clamping components 8 are arranged on both sides of the cargo platform 2 for clamping the goods on the cargo platform 2, and the clamping components 8 are used to clamp the shuttle and goods on the cargo platform 2, and two control components 9 are arranged on both sides of the elevator body 1 for controlling the clamping or release of the clamping components 8, and the control components 9 are used to make the clamping components 8 release the shuttle and goods at the shelf level, and clamp the shuttle and goods when rising and falling; the clamping component 8 includes two limit support plates 87 fixedly connected to both sides of the elevator body 1, and the limit support plates 87 provide guide rails for the limit slide 81, the limit slide 81 sliding in the limit support plates 87, and the limit slide 81 provides a moving platform for the ninth push rod 82, and a connecting rod 83 fixedly connected to the limit slide 81 and the cargo platform 2, and the connecting rod 83 is fixedly connected to one side of the cargo platform 2 and the bottom of the limit slide 81, and is used to support the limit slide 81 to move up and down.

[0021] Among them, the ninth push rod 82 that passes through the limiting slide 81 pushes the clamping plate 86 through the ninth push rod 82, and the clamping plate 86 is fixedly connected to the end of the ninth push rod 82, and is used to clamp the shuttle and the cargo through the clamping plate 86. The slide bar 84 fixedly connected to the surface of the ninth push rod 82 is used to cooperate with the trapezoidal seat 92 through the slide bar 84 to control the clamping plate 86 to open or clamp, and the spring 85 sleeved on the surface of the ninth push rod 82 pushes the slide bar 84 through the spring 85 to drive the clamping plate 86 to clamp the shuttle and the cargo. The spring 85 is located between the limiting slide 81 and the slide bar 84, and is used to push the slide bar 84 by means of the limiting slide 81; the control component 9 includes two guide seats 91 fixedly connected to both sides of the elevator body 1, and the trapezoidal seat 92 is limited by the guide seats 91; Among them, multiple trapezoidal seats 92 slide in the guide seat 91, and the guide seat 91 limits the trapezoidal seats 92 through the trapezoidal seats 92. The special-shaped slider 95 is fixedly connected to one side of the telescopic plate 3. The special-shaped slider 95 cooperates with the connecting rod 94. When the telescopic plate 3 is opened, the trapezoidal seat 92 is supported, and the length of the opening of the splint 86 is expanded.

[0022] Among them, two first strip rods 71 ​​are fixedly connected to the two sides of the bottom of the two telescopic plates 3. The telescopic plates 3 are slid in the cargo platform 2 and the telescopic plates 3 are limited by the first strip rods 71. The first strip rods 71 ​​pass through the cargo platform 2 and slide in the cargo platform 2. A through hole is provided at the bottom of the first strip rod 71 to limit the first strip rod 71, which facilitates the sliding of the first strip rod 71.

[0023] Combined with attachment Figure 1 -Attached Figure 8 The transmission assembly 7 includes a second bar 72 rotatably connected to the bottom of the cargo platform 2. The second bar 72 is rotated to transmit the driving force on the third bar 73, and the two third bar 73 connected to the two ends of the bottom of the second bar 72 are rotated respectively. One third bar 73 connects the force on the second bar 72, and the third bar 73 pushes the second bar 72, and rotates the guide rod 74 connected to the end of the third bar 73. The guide rod 74 transmits the thrust on the third bar 73 to push the telescopic plate 3 to open and close, and the electric push rod 75 fixedly connected to the bottom of the cargo platform 2. The electric push rod 75 is started to push the first bar 71, thereby driving one of the telescopic plates 3 to open, driving the third bar 73, the second bar 72 and the other third bar 73 to work together, thereby driving the other telescopic plate 3 to open.

[0024] The top of the guide rod 74 is fixedly connected to the bottom of the telescopic plate 3, and the force is transmitted to the guide rod 74 through the telescopic plate 3. The guide rod 74 runs through the cargo platform 2. A through hole is provided on the cargo platform 2 for the guide rod 74 to slide, which facilitates the movement of the guide rod 74 and slides in the cargo platform 2. The output end of the electric push rod 75 is fixedly connected to the bottom of one of the first strip rods 71. The piston rod of the electric push rod 75 can push the first strip rod 71, thereby driving the telescopic plate 3 to move.

[0025] Both sides of the trapezoidal seat 92 are fixedly connected with a cross limit rod 93, which passes through the guide seat 91 to limit the trapezoidal seat 92. Multiple trapezoidal seats 92 are fixedly connected by connecting rods 94. Instead of pushing the trapezoidal seats 92 one by one, all the trapezoidal seats 92 can be pushed directly, which is more convenient.

[0026] The surface of the special-shaped slider 95 fits with the surface of the connecting rod 94, and can slide better. The special-shaped slider 95 slides on the surface of the connecting rod 94. When the cargo platform 2 stops on the shelf layer, the special-shaped slider 95 fits with the connecting rod 94. When the cargo platform 2 stops on the shelf layer and needs to move, the special-shaped slider 95 slides with the connecting rod 94. When the cargo platform 2 is in the process of rising or falling, the special-shaped slider 95 and the connecting rod 94 slide relative to each other.

[0027] The surface of the slide bar 84 fits with the surface of the trapezoidal seat 92. When the cargo platform 2 is stationary on the shelf layer, the slide bar 84 fits with the trapezoidal seat 92, and the slide bar 84 slides on the surfaces of the trapezoidal seat 92 and the guide seat 91. When the cargo platform 2 is moving, the slide bar 84 slides on the surfaces of the trapezoidal seat 92 and the guide seat 91.

[0028] One end of the ninth push rod 82 is fixedly connected to a limit block 88, which limits the sliding length of the ninth push rod 82. A plurality of rollers are rotatably connected to the limit slide 81, which makes the limit slide 81 move more smoothly.

[0029] The splint 86 slides on the surface of the cargo platform 2, and the sliding makes it easy for the splint 86 to clamp the shuttle and cargo, or to move away from the shuttle and cargo. One side of the splint 86 is in contact with one side of the telescopic plate 3. When the splint 86 is to clamp the shuttle and cargo, the splint 86 is away from the telescopic plate 3. When the splint 86 is to release the cargo and the shuttle, it is in contact with and supports the telescopic plate 3.

[0030] Working principle: When the cargo platform 2 stops at the shelf level, the trapezoidal seat 92 will press the slide bar 84 and press the spring 85, so that the clamping plate 86 releases the shuttle and the cargo, making it easier for the shuttle to move out of the cargo platform 2 and into the shelf, or to move from the shelf into the cargo platform 2; When the cargo platform 2 leaves the shelf layer and moves, the slide bar 84 moves with the cargo platform 2, thereby moving along the surface track of the trapezoidal seat 92 and the guide seat 91. When the slide bar 84 moves to the guide seat 91, the spring 85 presses against the slide bar 84, driving the clamping plate 86 to clamp the shuttle and the cargo, making the shuttle and the cargo move more stably. Until the cargo platform 2 moves to the shelf layer, the shuttle and the cargo are released again. When a shuttle and cargo that exceeds the surface area of ​​the cargo platform 2 are placed on the cargo platform 2, the cargo platform 2 stops at the shelf layer, the electric push rod 75 is started, and the first bar 71 is pushed. Through the transmission of the transmission component 7, the two telescopic plates 3 are driven to open at the same time, thereby expanding the bearing area of ​​the cargo platform 2, so that the telescopic plate 3 drives the special-shaped slider 95 to push the connecting rod 94 and the trapezoidal seat 92, so that the trapezoidal seat 92 moves in the guide seat 91, so that the trapezoidal seat 92 pushes against the slide bar 84, driving the splint 86 to expand to both sides, thereby increasing the length of the opening of the splint 86, and facilitating the entry of larger shuttles onto the cargo platform 2 and the telescopic plate 3.
