DETAILED DESCRIPTION

[0018] In order to make the technical problems solved by the present invention, the technical solutions adopted and the technical effects achieved clearer, the technical solutions of the embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0019] like Figure 1-Figure 2 As shown, the blocking mechanism 1 includes a blocking member 11, a first limiting member 110 and a second limiting member 111. The blocking member 11 is configured to be rotatably mounted. When the blocking member 11 rotates to approach the first limiting member 110, it is in a blocking position state. When the blocking member 11 rotates to approach the second limiting member 111, it is in an avoiding position state.

[0020] The blocking member 11 is transformed between the blocking position state and the avoidance position state by rotation, and the rotation of the blocking member 11 is limited by the limiting member. When the blocking mechanism 1 needs to perform blocking, the blocking member 11 is close to the first limiting member 110, and when the blocking mechanism 1 needs to perform avoidance, the blocking member 11 is rotated to be close to the second limiting member 111. It can be understood that when the blocking member 11 is rotated to be close to the first limiting member 110, it is away from the second limiting member 111, and when the blocking member 11 is rotated to be close to the second limiting member 111, it is away from the first limiting member 110. The blocking mechanism 1 is used to prevent the vehicle from rushing out of the blocking mechanism track 12. The blocking member 11 is directly or indirectly hinged to the blocking mechanism track 12, and the blocking member 11 rotates around the hinge. In one embodiment, the blocking member 11 is installed on the blocking mechanism track 12 through a hinged connecting plate, and the hinged connecting plate is fixedly installed on the blocking mechanism track 12. The blocking member 11 is hinged to the hinged connecting plate, and a second limiting member 111 is arranged on the hinged connecting plate. The second limiting member 111 is a protrusion on the hinged connecting plate, which can support the blocking member 11 so that the blocking member 11 cannot continue to rotate.

[0021] The blocking mechanism 1 comprises two blocking mechanism rails 12 arranged in parallel, and hinged connecting plates are symmetrically arranged on the two blocking mechanism rails 12. The blocking member 11 comprises a horizontal portion and two bending portions, and the two bending portions are respectively hinged to the hinged connecting plates on both sides.

[0022] The first limit member 110 is installed on the blocking mechanism track 12. The first limit member 110 is a bending structure. The first bending portion of the bending structure is installed on the blocking mechanism track 12. The second bending portion of the bending structure is used to support the bending portion of the blocking member 11, so that the blocking member 11 cannot continue to rotate and stops in the blocking position.

[0023] The blocking mechanism 1 further comprises a support member 13, one end of which is connected to the blocking mechanism track 12, and the other end is connected to the mounting frame of the blocking mechanism track 12; an anti-collision buffer is also provided on the blocking member 11. The support member 13 is used to reinforce the blocking mechanism 1, one end of the support member 13 is connected to the blocking mechanism track 12, and the other end is generally connected to the column of the shelf, and the blocking mechanism track 12 is also installed on the column of the shelf. The connection relationship between the blocking mechanism track 12, the support member 13, and the shelf column 4 forms a triangular structure, which increases the stability and load-bearing capacity of the blocking mechanism track 12.

[0024] The blocking mechanism 1 further includes a proximity sensor 112, which is disposed near the first stopper 110 and / or the second stopper 111, and is used to detect the position state of the blocking member 11. In one embodiment, the proximity sensor 112 is a proximity switch, which is mounted on the blocking mechanism track 12 or on the support member 13.

[0025] The blocking mechanism 1 of the present application further includes a driving device, which is a driving motor for driving the blocking member 11 to rotate. The driving device is not shown in the figure.

[0027] In one embodiment, the hoist 2 includes two platforms and can be used as a maintenance hoist 2. When there is a vehicle in the stereoscopic warehouse that needs maintenance, the hoist 2 of the present application can carry a normal vehicle up to the layer where the vehicle that needs maintenance is located, and place the vehicle that needs maintenance on another empty platform, and then put the carried normal vehicle on the layer where the vehicle that needs maintenance is located. The hoist 2 includes a guide rail 23, which is vertically arranged on the ground. The guide rail 23 is provided with a plurality of guide surfaces. The guide mechanism 24 is connected to the platform. The guide mechanism 24 is provided with rollers.

Specifically, an electric hoist is arranged on the top of the hoist 2. The electric hoist winds the chain to drive the platform to move up and down. The electric hoist and the chain are not shown in the figure.

[0028] In one embodiment, the elevator 2 includes two platforms, namely a first platform 21 and a second platform 22, the first platform 21 and the second platform 22 are distributed along the up and down directions of the guide rail 23, the first platform 21 is provided with a first track 211, and the second platform 22 is provided with a second track 221; the installation component includes a vertical bracket 202, and the first platform 21 and the second platform 22 are fixedly installed on the vertical bracket 202. The first platform 21 and the second platform 22 are arranged one above and one below, and are respectively provided with a first track 211 and a second track 221 for transport vehicles to enter the platform. The platform carries the transport vehicle up and down, and vertical brackets 202 are provided on both sides of the platform as installation components. The first track 211 includes two groups of parallel tracks, and the second track 221 includes two groups of parallel tracks.

In order to strengthen the structure and increase the stability of the platform, two vertical brackets 202 are provided on each side of the platform.

[0029] The lifting machine 2 further includes an upper bracket 203 and a lower bracket 204, the first platform 21 and the second platform 22 are located between the upper bracket 203 and the lower bracket 204, and one end of the vertical bracket 202 is connected to the upper bracket 203 and the other end is connected to the lower bracket 204. Specifically, the vertical bracket 202 can be directly connected to the upper bracket 203 and the lower bracket 204, or can be connected through a transverse bracket 201 connector, for example, the ends of two vertical brackets 202 are connected through a transverse bracket 201 connector, and then one end of the upper bracket 203 is connected to the transverse bracket 201 connector on one side of the platform, and the other end is connected to the transverse bracket 201 connector on the other side of the platform, and the lower bracket 204 is connected in the same way.

[0030] The platform is provided with a middle platform stopper 205, and the platform stopper 205 is arranged at each end of the first track 211 and the second track 221.
