[0041] In the following, only some exemplary embodiments are simply described. As those skilled in the art can recognize, the described embodiments can be modified in various different ways without departing from the spirit or scope of the present application. Therefore, the drawings and the description are considered to be exemplary in nature rather than restrictive.

[0042] As Figure 1-12 shown, this embodiment provides an automatic loading system 100 for car carriers, including a track support frame 110, an automatic loading RGV 120, a telescopic track 130, and a hoisting shuttle car 140. The track support frame 110 is arranged in the front - rear direction, and the car carrier 200 to be loaded is parked inside the track support frame 110; on the left and right sides of the track support frame 110, there are respectively two layers of retractable track support arms 112; the so - called two layers refer to the upper layer and the lower layer, corresponding to the two - side loading surfaces of the car carrier 200. Each layer of the track support arm 112 is further divided into a left - right pair of track support arms 112, corresponding to the left and right sides of the telescopic track 130. Each column of track support arms 112 includes a plurality of track support arms 112; the so - called retractable means that it can be retracted and unfolded, that is, the track support arm 112 has two states, one is the retracted state, and the other is the unfolded state. In the retracted state, the track support arm 112 will not rub against the incoming or outgoing car carrier 200. In the unfolded state, the end of the track support arm 112 will extend into the carriage of the car carrier 200 to support the telescopic track 130 extending into the carriage. The automatic loading RGV 120 is used to park the automobile 300 to be loaded, and it is arranged movably relative to the track support frame 110. The automatic loading RGV 120 can move to the tail of the track support frame 110; in the initial state, the automatic loading RGV 120 is not at the tail of the track support frame 110, so as to leave a certain space to make it easier for the driver to drive the car carrier 200 straight into the track support frame 110; during loading, the automatic loading RGV 120 can move to the tail of the track support frame 110. The telescopic track 130 is arranged inside the automatic loading RGV 120 and above the automobile 300 to be loaded. The telescopic track 130 can extend forward into the carriage of the car carrier 200. During the extension process, under the support of the track support arm 112, the telescopic track 130 can maintain translation. The hoisting shuttle car 140 is arranged under the telescopic track 130 and is used to lift and lower the automobile 300 to be loaded. It is a device with the functions of lifting and holding the wheels.

[0043] In the initial stage, the automatic loading RGV 120 is not at the tail of the track support frame 110, and the track support arm 112 is in a retracted state; the car carrier 200 drives straight into the track support frame 110 from the tail of the track support frame 110, and this process has relatively low requirements for the driver; after the car carrier 200 stops, the automatic loading RGV 120 moves to the tail of the track support frame 110, facilitating the telescopic track 130 to extend forward into the track support frame 110. At the same time, the track support arm 112 changes from the retracted state to the deployed state to support the telescopic track 130; the hoisting shuttle car 140 hoists the car to be loaded 300 after holding the wheels of the car to be loaded 300; the telescopic track 130 extends forward and, under the support of the track support arm 112, moves into the carriage of the car carrier 200; the hoisting shuttle car 140 lowers the car to be loaded 300, and at this time the car to be loaded 300 is loaded on the car carrier 200; the telescopic track 130 retracts into the automatic loading RGV 120, and the track support arm 112 returns to the retracted state, and then the car carrier 200 can drive away from the track support frame 110. The automated loading method replaces manual loading, improving the loading efficiency, shortening the loading time, and there will be no scratches, reducing the requirements for the driver's technical level.

[0044] In one embodiment, the track support frame 110 includes a plurality of gantry frames 111. The gantry frames 111 are arranged in the left-right direction (referring to that its cross beam 1112 is arranged in the left-right direction), and the plurality of gantry frames 111 are arranged at equal intervals in the front-back direction; the gantry frame 111 includes two spaced-apart columns 1111 and a cross beam 1112 fixed to the tops of the two columns 1111. Installing the plurality of gantry frames 111 on the foundation 400 in sequence forms the track support frame 110, which is simple and convenient to install, has high construction efficiency, and short construction time; by using the gantry frame 111, due to the existence of the cross beam 1112, the columns 1111 are more stable and will not tilt inward after bearing the weight of the car to be loaded 300, the hoisting shuttle car 140, and the telescopic track 130.

[0045] In one embodiment, the track support frame 110 is not composed of gantry frames 111, but is composed of two rows of columns 1111 (that is, the cross beam 1112 of the gantry frame 111 is removed), which can be called a columnar frame. In this structure, in order to prevent the columns 1111 from tilting inward, diagonal stay wires are arranged on the outer sides of the columns 1111. One end of the diagonal stay wire is driven into the foundation 400, and the other end is fixed to the top of the column 1111. By arranging diagonal stay wires on the outer sides of the columns 1111, the columns 1111 are effectively prevented from tilting inward.

[0046] In one embodiment, the track support frame 110 adopts a steel structure frame similar in shape to the gantry 111. The steel structure frame is mainly composed of vertical bars, horizontal bars, diagonal braces, etc., which are connected by connectors such as clips and bolts (similar to structures such as scaffolding and shelves). Adjacent steel structure frames are connected by cross braces and diagonal braces. This structure has a relatively small skeleton, so it is not necessary to make the frame body (referring to the constituent unit of the track support frame 110) very thick, so less materials are used, which can effectively save materials and reduce material costs. When adopting a steel structure frame, the track support arm can be made into a standard unit that can be connected to the steel structure frame and then fixed on the steel structure frame, providing a basis for the standardization of the track support arm. It should be noted that how to achieve the standardization of the track support arm is not the problem to be solved in this application, so it will not be elaborated here.

[0047] The gantry 111, the column-shaped frame, and the steel structure frame in the above three embodiments are all steel structure frames and can be collectively referred to as steel frames.

[0048] Exemplarily, when constructing the foundation 400, anchor bolts are embedded. A flange plate or flange is provided at the bottom of the column 1111. After the anchor bolts pass through the bolt holes of the flange plate, nuts are tightened to complete the fixation of the column 1111 to the foundation 400.

[0049] The track support frame 110 is used for parking the car carrier 200 on the one hand and for installing the track support arm 112 on the other hand. Any other similar structure that meets the above two purposes can be used as the track support frame 110. Therefore, the structure of the track support frame 110 is not limited to the above two structures.

[0050] In one embodiment, each column 1111 is provided with two track support arms 112, that is, there are 4 track support arms 112 on each gantry 111. The two track support arms 112 of the same column 1111 are spaced apart in height. The two track support arms 112 at the same height of the same gantry 111 are a pair, and multiple pairs of track support arms 112 at the same height of different gantries 111 are one layer. The track support frame 110 supports the telescopic track 130 through the track support arms 112, and the telescopic track 130 hoists the vehicle to be loaded 300 through the hoisting shuttle car 140. That is to say, the track support arms 112 need to bear the weight of the vehicle to be loaded 300, the hoisting shuttle car 140, and the telescopic track 130. Therefore, the number of track support arms 112 provided should be sufficient, and the number of corresponding gantries 111 should also be sufficient.

[0051] In one embodiment, the rail support arm 112 is telescopically arranged in the left-right direction. In the retracted state, the end of the rail support arm 112 (referring to the end facing inside the rail support frame 110, which is also the end for supporting the retractable rail) is close to the column 1111, so as to prevent the end of the rail support arm 112 from affecting the entry or exit of the car carrier 200 into or out of the rail support frame 110; in the deployed state, the rail support arm 112 moves into the rail support frame 110, and its end can extend into the carriage of the car carrier 200, so as to provide support for the retractable rail 130 extending in. A collision detection sensor is provided at the end of the rail support arm 112. When a collision is detected by the collision detection sensor, it means that the rail support arm 112 corresponds to the physical part of the car carrier 200, and the rail support arm 112 will immediately change to the retracted state. A support pulley 1121 for supporting the retractable rail 130 is provided at the end of the rail support arm 112. During the process of the retractable rail 130 extending into the carriage, it abuts against the support pulley 1121. It should be noted that the left-right movement of the rail support arm 112 can be powered by a cylinder, a hydraulic cylinder or a motor, and operates under the control of a control system (PLC and HMI).

[0052] In one embodiment, the rail support arm 112 is swingably arranged. Exemplarily, the rail support arm 112 rotates around a vertical axis. In the retracted state, the rail support arm 112 faces the column 1111 of the other gantry 111. Exemplarily, the rail support arm 112 swings around a horizontal axis. In the retracted state, the end of the rail support arm 112 faces the sky or the ground. Similar to the previous embodiment, a collision detection sensor and a support pulley 1121 are provided at the end of the rail support arm 112, which is powered by a cylinder, a hydraulic cylinder or a motor and operates under the control of a control system.

[0053] In one embodiment, two limit guide tubes 113 are provided on the open space inside the rail support frame 110. The limit guide tubes 113 are installed on the foundation 400. The limit guide tubes 113 are arranged in the front-back direction, and the two limit guide tubes 113 are spaced apart in the left-right direction. The limit guide tubes 113 are used to limit the parking position of the car carrier 200 and keep the car carrier 200 straight for loading. At the inlet and outlet (the head and tail ends) of the rail support frame 110, the two limit guide tubes 113 are in a flared shape, which is more convenient for the car carrier 200 to enter and exit.

[0054] In one embodiment, an RGV track 125 extending in the left-right direction is laid on the open space at the tail of the track support frame 110. The RGV track 125 is fixed to the foundation 400, and the automatic loading RGV 120 is arranged on the RGV track 125. In this way, after the car carrier 200 drives into the track support frame 110, the automatic loading RGV 120 can move along the RGV track 125 to the tail of the track support frame 110, so that the telescopic track 130 can extend into the track support frame 110 and the carriage of the car carrier 200.

[0055] In one embodiment, the track support frame 110 is installed on a floor that can move in the left-right direction, and the automatic loading RGV 120 cannot move. The floor drives the track support frame 110 to move, so that the automatic loading RGV 120 moves relatively to the tail of the track support frame 110. Exemplarily, the foundation 400 where the floor is located can be a sunken foundation 400. Tracks are laid on the sunken foundation 400, and the floor is installed on the tracks. The upper surface of the floor is at the same height as the upper surfaces of other foundations 400.

[0056] In one embodiment, the automatic loading RGV 120 is divided into two layers, and each layer is provided with a telescopic track 130. At least one pair (i.e., two) of lifting shuttle cars 140 are arranged under each telescopic track 130. Exemplarily, the automatic loading RGV 120 includes a horizontally arranged bottom plate 121, an intermediate partition 122, and a top plate 123. The three plates are spaced apart in height and are supported by the main body 124. The bottom plate 121 and the intermediate partition 122 can carry the cars 300 to be loaded. The telescopic tracks 130 are installed below the intermediate partition 122 and the top plate 123. Exemplarily, 4 pairs of lifting shuttle cars 140 are arranged under the telescopic track 130. One pair of lifting shuttle cars 140 can lift a car 300 to be loaded. In this way, 8 cars 300 to be loaded can be loaded at a time. The number of lifting shuttle cars 140 can be designed according to the sizes of the car carrier 200 and the cars 300 to be loaded. Exemplarily, a plurality of fixed supports similar to the track support arms 112 are arranged under the top plate 123, and the telescopic tracks 130 are arranged on the fixed supports; it is stipulated that support pulleys 1121 are arranged at the ends of the supports.

[0057] In one embodiment, the automatic loading RGV 120 has only one layer but can be lifted. After being lifted, the retractable track 130 can correspond to the track support arm 112 of the upper layer, and after being lowered, the retractable track 130 can correspond to the track support arm 112 of the lower layer. Thus, the double-layer space of the car carrier 200 can be loaded using a set of retractable tracks 130. Exemplarily, the automatic loading RGV 120 includes a bottom plate 121 and a top plate 123, which are connected by telescopic columns. The telescopic columns are pneumatic, hydraulic or electric and act under the control of a control system. When loading the lower layer, there is no particularity. When loading the upper layer, the hoisting shuttle car 140 first lifts the car 300 to be loaded, and then the telescopic column jacks up the top plate 123. After the retractable track 130 corresponds to the track support arm 112 of the upper layer, the jacking is stopped.

[0058] In one embodiment, the hoisting shuttle car 140 includes a top driving unit 141, a telescopic lifting arm 142, a swing arm 143 and a support rod 144. The top driving unit 141 can move along the retractable track 130. In this way, the distance between a pair of hoisting shuttle cars 140 is adjustable, so that cars 300 to be loaded with different wheelbases can be hoisted. A telescopic lifting arm 142 is vertically arranged on each of the left and right sides of the top driving unit 141, corresponding to the left and right wheels of the car 300 to be loaded respectively. Exemplarily, the telescopic lifting arm 142 adopts a hydraulic telescopic arm. A swing arm 143 is arranged at the lower end of the telescopic lifting arm 142, and the swing arm 143 is generally arranged in the front-rear direction. A support rod 144 is arranged at each of the front and rear ends of the swing arm 143. The support rod 144 can rotate around a vertical axis. After the two support rods 144 installed on the same swing arm 143 swing towards each other, they can hold the bottom of the wheels of the car 300 to be loaded. Exemplarily, one end of the support rod 144 is rotatably connected to the vertical axis at the front end or the rear end of the swing arm 143. Under the control of the control system, the support rod 144 rotates around the vertical axis driven by a cylinder, a hydraulic cylinder, etc., so as to realize the clamping and loosening of the wheels. Generally, the support rod 144 can rotate around the vertical axis within 90°.

[0059] In one embodiment, the retractable track 130 is provided with a wheel groove 131. Moving wheels 1411 are respectively arranged at the four corners of the top driving unit 141, and at least one moving wheel 1411 is a driving wheel. The moving wheels 1411 are located in the wheel groove 131. In this way, the movement of the hoisting shuttle car 140 can be realized. A driving motor is arranged inside the top driving unit 141 and drives the driving wheel to rotate forward or backward under the control of the control system.

[0060] In one embodiment, the retractable track 130 is provided with a track groove 132. The track groove 132 is located outside the wheel groove 131. The support pulley 1121 at the end of the track support arm 112 is located in the track groove 132. In this way, when the retractable track 130 moves under the support of the track support arm 112, the frictional resistance can be effectively reduced.

[0061] In one embodiment, the swing arm 143 is pivotally connected to the lower end of the telescopic boom 142 through a pivot shaft. The pivot shaft is arranged in the left - right direction. The swing arm 143 can swing within ±45° around the pivot shaft. When unloading the to - be - loaded vehicle 300 onto the inclined car body of the carriage, through the adaptive swing of the swing arm 143, the to - be - loaded vehicle 300 can be smoothly in contact with the inclined car body. Exemplarily, a lug 1431 protruding upward is provided in the middle of the swing arm 143, and a groove 1421 for cooperating with the lug 1431 is arranged at the lower end of the telescopic boom 142. The lug 1431 extends into the groove 1421 and is connected through a pivot shaft, thereby realizing the rotatable connection between the swing arm 143 and the telescopic boom 142. Under the limiting action of the solid part of the telescopic boom 142 and the solid part of the swing arm 143, the swing arm 143 can only swing within a certain range; the swing angle is determined by the gap of the solid part. This is a common limited - angle swing structure design and will not be elaborated further.

[0062] In one embodiment, the telescopic track 130 performs extension and retraction actions driven by a drive motor installed under the top plate 123 of the automatic loading RGV120. The drive motor operates under the control of the control system and drives the telescopic track 130 to move through a gear - rack structure or a sprocket - chain structure.

[0063] In one embodiment, a load sensor is provided on the telescopic boom 142. When unloading the to - be - loaded vehicle 300, after the wheels contact the car body of the carriage, the measured value of the load sensor will drop significantly. When it drops to a preset extreme value, the telescopic boom 142 stops descending under the control of the control system.

[0064] In one embodiment, a 3D vision sensor is provided under the lifting and transporting shuttle 140 to determine the position of the wheels of the to - be - loaded vehicle 300. Under the control of the control system, after the lifting and transporting shuttle 140 moves to the corresponding position, it hoists the to - be - loaded vehicle 300 parked on the automatic loading RGV120.

[0065] In one embodiment, the vehicle 300 to be loaded is parked at a designated position on the automatic loading RGV 120, and the hoisting shuttle car 140 can accurately move to the position where the wheels are located under the control of the control system. Exemplarily, an automatic parking robot is adopted, and the vehicle 300 to be loaded is moved to the designated position on the automatic loading RGV 120 by using laser positioning or QR code positioning. Exemplarily, barcodes are arranged along the length direction of the telescopic track 130, and a barcode reader is arranged at the position of the top drive unit 141 facing the barcode, so that the accurate position of the hoisting shuttle car 140 can be obtained and the hoisting shuttle car 140 can run to the accurate position. Exemplarily, for the second layer platform of the automatic loading RGV 120, the vehicle 300 to be loaded is lifted by the intelligent lifting platform and then moved to the designated position by the automatic parking robot.
