[0001] The utility model relates to the technical field of parking AGV carriers, in particular to an AGV carrier for hooking and pulling vehicles. Background Art

[0002] A parking AGV carrier, that is, an automated guided vehicle used in a parking garage or parking lot, is an intelligent device that can automatically transport vehicles to parking spaces. The development process of the parking AGV carrier reflects the important role of technological progress in improving social efficiency and solving practical problems. Its future development will be more closely combined with trends such as intelligentization, networking, environmental protection and energy conservation, and become an important part of the intelligent city and intelligent transportation system.

[0003] At present, for some vehicle AGV carriers, due to their relatively high height, in order to prevent scratching the car chassis, a bracket needs to be made to lift the vehicle before the vehicle can be stored or retrieved, which increases the manufacturing cost and failure rate, and the user experience is poor. For some vehicle AGV carriers, rubber belts are used to pick up the vehicle by friction, which will cause the car tires to slip between the belts, easily resulting in vehicle deviation and failures. Therefore, an AGV carrier for hooking and pulling vehicles is proposed to solve the above problems. Content of the Utility Model

[0004] Aiming at the deficiencies of the prior art, the utility model provides an AGV carrier for hooking and pulling vehicles, which has the advantages of simple control, reliable operation, strong obstacle-crossing ability, large driving force, high speed and low failure rate, and solves the problems that for some current vehicle AGV carriers, due to their relatively high height, in order to prevent scratching the car chassis, a bracket needs to be made to lift the vehicle before the vehicle can be stored or retrieved, which increases the manufacturing cost and failure rate, and the user experience is poor; for some vehicle AGV carriers, rubber belts are used to pick up the vehicle by friction, which will cause the car tires to slip between the belts, easily resulting in vehicle deviation and failures.

[0005] To achieve the above object, the utility model provides the following technical solution: an AGV carrier for hooking and pulling vehicles, including a hooking component, a vehicle-picking component, a traveling component, a frame component and a raceway component. The frame component includes a middle skeleton, and a plurality of connecting rods are fixedly connected to both the top surface and the bottom surface of the middle skeleton. Side beams are fixedly connected between the side surfaces of the plurality of connecting rods on the same side away from the middle skeleton, and two corner wheels are fixedly connected to the two side beams.

[0006] The vehicle picking component includes a first motor, which is fixedly installed on the middle frame. The output end of the first motor is fixedly connected with a chain drive. The two ends of the chain drive are respectively fixedly connected with a driving component and a power transmission shaft. A tire pushing frame is placed on the top of the driving component. A chain is sleeved between the tire pushing frame and the driving component. A steering wheel is connected inside the chain through a sprocket. A chain anti-sagging device is arranged inside the chain.

[0007] Furthermore, the number of the hooking components is two and they are respectively fixedly installed on the left and right sides of the frame component. The vehicle picking component is located between the four corner wheels. The number of the chains is four.

[0008] Furthermore, the traveling component includes a second motor, which is fixedly installed on the middle frame. The output end of the second motor is fixedly installed with a first gear. The first gear meshes with a second gear. A driving shaft is fixedly installed inside the second gear. A third gear is fixedly sleeved on the outer peripheral wall of the driving shaft.

[0009] Furthermore, the number of the traveling components is two. Both of the two traveling wheels are located at the bottom of the frame component.

[0010] Furthermore, the number of the raceway components is two. The raceway component is composed of multiple groups of rollers and is fixedly installed on the frame component. The rollers are located in front of the connecting rod.

[0011] Compared with the prior art, the technical solution of the present application has the following beneficial effects:

[0012] 1. For the AGV carrier of the hook-pulling vehicle, two traveling wheels are adopted for differential control to control the traveling speed of the traveling wheels, so as to control the traveling direction of the entire carrier. The traveling wheels are on the outside of the vehicle and there is no height limit. Larger wheel diameters and driving motors with larger power can be set, which greatly enhances the obstacle-crossing ability and climbing ability, and correspondingly increases the driving force.

[0013] 2. For the AGV carrier of the hook-pulling vehicle, under the action of the tire pushing frame, the vehicle tires are pushed to move by the tire pushing frame. The parking position is accurate and the tire pushing frame gives a horizontal limit to the vehicle tires on the carrier, so as to avoid failures caused by slipping during operation and inaccurate parking positions. At the same time, the traveling component travels longitudinally and is arranged more flexibly. BRIEF DESCRIPTION OF THE DRAWINGS

Specific implementation manner

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] Please refer to Figures 1 to 6 , an AGV transporter for hooking and retrieving vehicles in this embodiment includes a hook component 1, a vehicle retrieval component 2, a traveling component 3, a frame component 4, and a raceway component 5. The frame component 4 includes a middle skeleton 403. A plurality of connecting rods 404 are fixedly connected to both the top surface and the bottom surface of the middle skeleton 403. Side beams 402 are fixedly connected between the side surfaces of the plurality of connecting rods 404 on the same side away from the middle skeleton 403. Two corner wheels 401 are fixedly connected to the two side beams 402.

[0023] The vehicle picking component 2 includes a first motor 206, which is fixedly installed on the middle frame 403. The output end of the first motor 206 is fixedly connected with a chain drive 208. The two ends of the chain drive 208 are respectively fixedly connected with a drive assembly 205 and a power transmission shaft 207. A tire pushing frame 202 is placed on the top of the drive assembly 205. A chain 203 is sleeved between the tire pushing frame 202 and the drive assembly 206. A steering wheel 201 is connected inside the chain 203 through a sprocket. A chain anti-drooping device 204 is arranged inside the chain 203. The number of the hooking components 1 is two and they are respectively fixedly installed on the left and right sides of the frame component 4. The vehicle picking component 2 is located between the four corner wheels 401. The number of the chains 203 is four. The number of the track components 5 is two. The track component 5 is composed of multiple groups of rollers 501 and is fixedly installed on the frame component 4. The rollers 501 are located in front of the connecting rod 404.

[0024] Specifically, the AGV carrier completes hooking and picking up the vehicle tire through a set of hooking components 1. When the AGV carrier runs to the bottom of the vehicle, after the first roller 501 at one end contacts the vehicle tire, the detection system detects the vehicle tire at this time. The hooking component 1 hooks the tire from the other side of the vehicle tire. Then the hooking component 1 moves horizontally to hook the vehicle tire onto the first roller 501. When the vehicle tire is picked up by the first roller 501, the first motor 206 is powered on and rotates. The rotation is transmitted to the drive assemblies 205 on both sides through the chain drive 208 at its front end. The drive assemblies 205 drive the four chains 203 to start running horizontally. The tire pushing frames 202 installed on the chains 203 also start running horizontally, pushing the two vehicle tires to run horizontally under the rolling support of the bottom rollers 501. When the tire picking operation is in place, the first motor 206 stops running, and the carrier completes picking up the vehicle.

[0025] The traveling component 3 includes a second motor 301, which is fixedly installed on the middle frame 403. The output end of the second motor 301 is fixedly installed with a first gear 302. The first gear 302 meshes with a second gear 303. A drive shaft 304 is fixedly installed inside the second gear 303. A third gear 305 is fixedly sleeved on the outer peripheral wall of the drive shaft 304. The third gear 305 meshes with an idler gear 306. A traveling wheel 307 is fixedly installed on the idler gear 306. The number of the traveling components 3 is two. The two traveling wheels 307 are both located at the bottom of the frame component 4.

[0026] Specifically, start the second motor 301. The output of the second motor 301 drives the first gear 302 to rotate. Through the meshing between the first gear 302 and the second gear 303, the drive shaft 304 is driven to rotate. Furthermore, through the cooperation between the third gear 305 and the idler gear 306, the driving wheel 307 is driven to rotate. The AGV carrier completes the functions of forward, backward, turning, and rotation during horizontal movement through the differential control of two sets of traveling components 3. For example, forward: both driving wheels 307 run forward simultaneously; backward: both driving wheels 307 run backward simultaneously; turning: one driving wheel 307 runs fast and the other runs slow; rotation: one driving wheel 307 rotates forward and the other rotates backward. When the vehicle is placed from the carrier onto the ground parking space, the first motor 206 is energized to rotate. The rotation is transmitted to the driving components 205 on both sides through the chain drive 208 at its front end. The driving components 205 drive the four chains 203 to start horizontal movement. The tire pushing frames 202 installed on the chains 203 also start horizontal movement, pushing the two vehicle tires to move horizontally under the rolling support of the bottom rollers 501. When the tires reach the rear position of the outermost roller 501, the first motor 206 stops running, and the second motor 301 starts running. The AGV carrier starts to move, completing the vehicle placement of the AGV carrier.

[0027] The working principle of the above embodiment is as follows:

[0028] The AGV transporter uses a set of hooking components 1 to hook and pull the vehicle tires. When the AGV transporter runs to the bottom of the vehicle and the first roller 501 at one end contacts the vehicle tire, the detection system detects the vehicle tire at this time. The hooking component 1 hooks the tire from the other side of the vehicle tire, and then the hooking component 1 moves horizontally to hook the vehicle tire onto the first roller 501. At this time, after the vehicle tire is picked up by the first roller 501, the first motor 206 is energized to rotate, and the rotation is transmitted to the drive components 205 on both sides through the chain drive 208 at its front end. The drive components 205 drive the four chains 203 to start running horizontally. The tire pushing frames 202 installed on the chains 203 also start running horizontally, pushing the two vehicle tires to run horizontally under the rolling support of the bottom rollers 501. When the tire picking operation is in place, the first motor 206 stops running, and the vehicle picking by the transporter is completed. Then the second motor 301 is started. The output of the second motor 301 drives the first gear 302 to rotate. Through the meshing between the first gear 302 and the second gear 303, the drive shaft 304 is driven to rotate. Then, through the cooperation between the third gear 305 and the idler gear 306, the walking wheels 307 are driven to rotate. The AGV transporter uses two sets of walking components 3 to perform differential control to complete the forward, backward, turning, and rotating functions of horizontal movement. For example, forward: the two walking wheels 307 run forward simultaneously; backward: the two walking wheels 307 run backward simultaneously; turning: one of the two walking wheels 307 runs fast and the other runs slow; rotating: one of the two walking wheels 307 rotates forward and the other rotates backward. When the vehicle is placed from the transporter onto the ground parking space, the first motor 206 is energized to rotate, and the rotation is transmitted to the drive components 205 on both sides through the chain drive 208 at its front end. The drive components 205 drive the four chains 203 to start running horizontally. The tire pushing frames 202 installed on the chains 203 also start running horizontally, pushing the two vehicle tires to run horizontally under the rolling support of the bottom rollers 501. When the tire runs to the rear position of the outermost roller 501, the first motor 206 stops running, and the second motor 301 starts running. The AGV transporter starts walking, and the vehicle placing by the AGV transporter is completed.
