[0023] To make the above-mentioned objects, features, and advantages of the present invention more clearly understood, the following detailed description of specific embodiments of the present invention is provided in conjunction with the accompanying drawings. The following description sets forth many specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art may make similar modifications without departing from the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0024] This embodiment provides a gantry and handling equipment capable of forking or transporting multiple pallets at a time.

[0025] Figure 1 2 is a cross-sectional view of the traveling wheel mechanism in this embodiment.

[0026] In one embodiment, the present application provides a walking wheel mechanism, comprising:

[0027] A wheel body 11 and an axle 12, with a bearing 13 provided between the wheel body 11 and the axle 12;

[0028] A transmission member 14 is mounted on the axle 12 and connected to the wheel 11, driving the wheel 11 to rotate. The axle 12 is configured so that when the transmission member 14 drives the wheel 11 to rotate, the axle 12 does not rotate. The axle 12 only provides support and does not rotate. The bearing 13 is mounted inside the wheel and is subject only to positive pressure.

[0029] A ball bearing 13 is provided between the wheel body 11 and the axle 12 , and the wheel body 11 is driven to rotate via a transmission member 14 . Since the bearing 13 is provided between the wheel body 11 and the axle 12 , the axle 12 does not rotate when the wheel body 11 rotates.

[0030] The transmission member 14 is a sprocket mechanism, which is arranged on the axle 12 and driven by a chain. The sprocket mechanism is driven by another chain, and the rotation of the sprocket drives the wheel body 11 to rotate. A bearing 13 is provided between the sprocket and the axle 12, so when the sprocket rotates, the axle 12 does not rotate with it.

[0031] In one embodiment, the present application also provides a walking wheel set, see Figure 2 , including at least three of the aforementioned walking wheel mechanisms 10, the three walking wheel mechanisms 10 are located on the same walking surface, the three walking wheel mechanisms 10 are arranged in sequence, and every two adjacent ones are driven by a connecting piece.

[0032] The three walking wheel mechanisms 10 are arranged in a straight line on the same walking surface, and power is transmitted in sequence through a sprocket chain mechanism. A chain is set between two adjacent walking wheel mechanisms 10, and two chains are set on the middle walking wheel mechanism 10, one of which is connected to the walking wheel mechanism 10 on one side, and the other chain is connected to the walking wheel mechanism 10 on the other side.

[0033] The three walking wheel mechanisms 10 include a first walking wheel mechanism 101, a second walking wheel mechanism 102 and a third walking wheel mechanism 103. The first walking wheel mechanism 101 and the second walking wheel mechanism 102 are connected by a first chain 1013, and the second walking wheel mechanism 102 and the third walking wheel mechanism 103 are connected by a second chain 1023.

[0034] A first transmission member 1011 and a second transmission member 1012 are arranged on the first traveling wheel, and the first transmission member 1011 transmits the second transmission member 1012; a third transmission member 1021 and a fourth transmission member 1022 are arranged on the second traveling wheel, and the third transmission member 1021 transmits the fourth transmission member 1022; a fifth transmission member 1031 is arranged on the third traveling wheel; the second transmission member 1012 is connected to the third transmission member 1021 via a chain transmission, and the fourth transmission member 1022 is connected to the fifth transmission member 1031 via a chain transmission.

[0035] Two sprockets are set on the first walking wheel, namely the first sprocket and the second sprocket. The first transmission member 1011 and the second transmission member 1012 are coaxially arranged. The rotation of the first transmission member 1011 drives the second transmission member 1012 to rotate. The first transmission member 1011 is driven by other chain mechanisms. That is to say, the first sprocket and the second sprocket are coaxially arranged, the first sprocket drives the second sprocket to rotate, and the first sprocket is driven by other chains.

[0036] The third transmission member 1021 and the fourth transmission member 1022 are coaxially arranged. The rotation of the third transmission member 1021 drives the rotation of the fourth transmission member 1022. The third transmission member 1021 is a third sprocket, and the fourth transmission member 1022 is a fourth sprocket. A first chain 1013 is disposed between the second and third sprockets. A fifth sprocket is disposed on the third traveling wheel. A second chain 1023 is disposed between the fourth and fifth sprockets.

[0037] The traveling wheel assembly further includes a drive sprocket 1001, which is directly or indirectly connected to the output shaft of the motor and is in transmission connection with the first transmission member 1011. The drive sprocket 1001 is in transmission connection with the first sprocket via a drive chain 1002. The motor drives the drive sprocket 1001 to rotate via a transmission shaft 20. Specifically, the output shaft of the motor drives the transmission shaft 20 to rotate via a sprocket chain. The transmission shaft 20 is connected to the drive sprocket 1001, driving the drive sprocket 1001 to rotate.

[0038] The wheel assembly also includes a fourth wheel 104, which is a driven wheel. The fourth wheel 104 is arranged on the same running surface as the first, second, and third wheels, forming a straight line. The fourth wheel 104 can be adjacent to either the first or second wheel.

[0039] When a vehicle passes through a gap at a track change and its drive wheels simultaneously fall into the gap, it can lose power and lose control of its speed, or even collide with the edge of a shelf gap, affecting overall balance and safety. The present invention utilizes two sets of chains and sprockets to link the three running wheels. This increases the proportion of the vehicle's drive wheels, ensuring a continuous supply of driving force when passing through shelf gaps and reducing the possibility of wheel impacts. This also ensures that if a drive wheel falls into a track gap, the remaining drive wheels can continue to provide power. A chain and sprocket transmission system is located between each pair of drive wheels to ensure continuous transmission of driving force. With multiple drive wheels, each pair has a transmission system. At least three sets of wheels are on the same plane of guide rails at the track change. When the vehicle passes through the track, at least three sets of wheels are on the same plane of guide rails, ensuring overall vehicle stability and preventing sagging at the drop due to center of gravity issues, which could cause the wheels to impact the guide rail section. This provides a smooth and stable drive, ensuring greater vehicle stability when crossing the track and preventing collisions with the guide rail section. This reduces cargo slippage during startup.

[0040] In one embodiment, the present application further provides a transport vehicle, comprising the aforementioned traveling wheel assembly, wherein the traveling wheel assembly is arranged on both sides of the traveling direction of the transport vehicle.

[0041] The traveling wheel groups on both sides of the transport vehicle in the traveling direction are connected by a transmission shaft 20 . The transport vehicle includes a driving motor 30 , and the driving motor 30 drives the transmission shaft 20 to rotate.

[0042] Specifically, a set of running wheels is provided on each side of the transporter in the direction of travel. The drive sprockets 1001 of the two running wheels are connected by a transmission shaft 20. A motor drives the transmission shaft 20 to rotate, thereby realizing the movement of the transporter. The wheels are rigidly connected to the vehicle body and are only subjected to bending moments.

[0043] The above-described embodiments merely represent several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present utility model patent shall be determined by the appended claims.
