[0023] The following will be combined with the drawings in this embodiment to clearly and completely describe the technical solution in this embodiment. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0024] like Figure 1 , Figure 2 , Figure 3As shown, the present embodiment discloses a tray rack for freeze-drying equipment, comprising a suspension 1, a tray rack 2, and a movable bottom bracket 3. The suspension 1 is fixedly mounted on the inner top of the freeze-drying equipment. A top rail assembly 22 is provided at the upper end of the tray rack 2. The suspension 1 comprises a frame plate 11, which is located at the lower end of the suspension 1 and extends to both sides of the suspension 1. The top rail assembly 22 is provided with a track groove 221, which is connected to the upper end surface of the top rail assembly 22. Top plates 222 are formed on both sides of the upper end opening of the track groove 221. A plurality of first pulleys 223 are installed on the top plate 222, and the plurality of first pulleys 223 are distributed along the length direction of the top rail assembly 22. The frame plate 11 is located inside the track groove 221, and the lower end of the first pulley 223 abuts against the upper end surface of the frame plate 11. The first pulley 223 is used to support the top plate 222 and the frame plate 11. The first pulley 223 enables the tray rack 2 to slide along the suspension 1.

[0025] like Figure 2 As shown, the first pulley 223 includes a roller 2231, a connecting rod 2232, a spring 2233, and a limit block 2234. The roller 2231 is rotatably mounted on the connecting rod 2232. The connecting rod 2232 is slidably connected to the top plate 222. The connecting rod 2232 penetrates the top plate 222. The limit block 2234 is fixedly mounted on the upper end of the connecting rod 2232 to form a downward limit of the connecting rod 2232. The spring 2233 is sleeved on the connecting rod 2232. The spring 2233 is located on the lower end surface of the roller 2231 and the top plate 222. The roller 2231 is pressed by the spring 2233 so that the lower end of the roller 2231 is always pressed against the upper end surface of the frame plate 11. The spring 2233 can play a certain role in buffering and relieving the roller 2231. The roller 2231 can be extended and retracted up and down so that when the frame plate 11 is inserted into the track groove 221, even if there is a slight upward and downward position offset between the frame plate 11 and the roller 2231, the roller 2231 can be pressed by the frame plate 11 and then contact the upper end surface of the frame plate 11, so that the top rail assembly 22 can slide normally along the suspension 1.

[0026] like Figure 1 As shown, the pallet rack 2 is provided with a plurality of pallet frames 21 arranged vertically, and a pallet can be placed in each pallet frame 21. A support frame 23 is provided at the lower end of the pallet rack 2, and the support frame 23 includes a support plate 231. The support plate 231 is located at the lower end of the support frame 23 and extends horizontally to both sides of the support frame 23. The movable base 3 is provided with a support assembly 31, and the support assembly 31 includes a support groove 311. The support plate 231 is located in the support groove 311, and the support plate 231 can slide along the support groove 311. More preferably, a plurality of rollers 312 arranged along the length direction of the support groove 311 are provided in the support groove 311, and the upper ends of the plurality of rollers 312 form a plane supporting the support plate 231. The rollers 312 can reduce the friction of the lower end surface of the support plate 231 so that it can slide better in the support groove 311.

[0027] The upper end opening of the support groove 311 is for the support plate 231 to pass through, and multiple second pulleys 313 are installed on both sides of the upper end opening of the support groove 311. The multiple second pulleys 313 are arranged along the length direction of the support groove 311, and the lower end of the second pulley 313 is against the upper end surface of the support plate 231. The second pulley 313 has the same structure as the first pulley 223. The second pulley 313 can be extended and retracted up and down, and the second pulley 313 can be pressed against the upper end surface of the support plate 231. When the support plate 231 is located in the support groove 311, the second pulley 313 supports the entire pallet rack 2, and can prevent the pallet rack 2 from tilting on the movable base 3.

[0028] like Figure 1 , Figure 3 , Figure 4 , Figure 5 As shown, the movable base 3 includes a base plate 32 and a driving mechanism 33. The support assembly 31 and the driving mechanism 33 are installed on the upper end surface of the base plate 32.

The motor 331 is connected to the screw rod 332 through transmission. The transmission method is gear transmission or belt transmission. The screw rod 332 and the guide rod 333 are respectively located on both sides of the support assembly 31. The screw rod 332 and the guide rod 333 are arranged parallel to the support plate 231. One end of the cross rod 334 is threadedly connected to the screw rod 332. Bearings are installed at the threaded connection end of the cross rod 334 and the screw rod 332, so that the screw rod 332 can drive the cross rod 334 to move along the guide rod 333 when rotating. The other end of the cross rod 334 is slidably connected to the guide rod 333. The motor 331 drives the screw rod 332 to rotate. The cross bar 334 can move along the screw rod 332, and the guide rod 333 is connected to the cross bar 334 through a linear bearing to play a guiding role. The cross bar 334 is located above the support assembly 31, and the cross bar 334 is installed with a fastener 335, which can be detachably connected to the support plate 231, and the fastener 335 is rotatably connected to the cross bar 334. The fastener 335 is provided with a block 336. The upper end surface of the support plate 231 is provided with a slot 232 corresponding to the block 336, and the slot 232 is provided with a closing portion 2321. The closing portion 2321 is located on the side of the slot 232 facing the cross bar 334. The setting of the closing portion 2321 can limit the block 336 in the horizontal direction, and the fastener 335 rotates so that the block 336 can be buckled into or out of the slot 232. After the block 336 is rotated and snapped into the slot 232, the movement of the cross bar 334 can drive the tray rack 2 to move along the support groove 311.

[0029] like Figure 1 , Figure 4As shown, the pallet rack 2 includes a first state, a second state and a third state. In the first state, the support frame 23 is completely located in the support assembly 31, and the top rail assembly 22 partially and completely leaves the suspension 1. At this time, the pallet rack 2 is located on the movable base 3, and the card block 336 remains inserted into the card slot 232. The loaded pallet rack 2 or the freeze-dried pallet rack 2 can be transported by moving the base 3. In the second state, the support frame 23 is at least partially located in the support assembly 31, and the top rail assembly 22 is at least partially located on the suspension 1. At this time, the pallet rack 2 is in the process of being hung in or out of the suspension 1, and the motor 331 is driving the screw rod 332 to rotate and then push the cross bar 334 toward the suspension 1. Move in the direction of moving or moving away from the suspension 1. In the third state, the top rail assembly 22 is completely located on the suspension 1, and the support frame 23 is completely away from the support assembly 31. At this time, the tray rack 2 is completely suspended on the suspension 1, and the tray rack 2 is completely in the freeze-drying equipment. The block 336 is rotated to disengage from the slot 232, and the fastener 335 is disengaged from the support plate 231. The movable bottom bracket 3 is separated from the tray rack 2, and the door of the freeze-drying equipment can be closed to perform freeze-drying operations. After freeze-drying is completed, the support plate 231 is aligned with the support slot 311, the block 336 is rotated to be inserted into the slot 232, and the motor 331 is started to make the tray rack 2 enter the second state from the third state and then to the first state.
