[0019] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be clearly and completely described below in combination with the specific embodiments of the utility model and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] In order to solve the technical problems in the prior art, the utility model is further described in conjunction with the accompanying drawings and embodiments:

[0021] like Figure 1-Figure 2 As shown, the utility model discloses an automatic loading and unloading lifting and movable trolley for an aging room, comprising a trolley body 1, a lifting mechanism 3, a telescopic mechanism 5 and a supporting assembly 4. A sliding assembly 11 and a driving assembly are installed at the bottom of the trolley body 1. A conveying track 2 is laid in the aging room. A plurality of aging racks are arranged along the length direction of the conveying track 2 in the aging room. The sliding assembly 11 is slidably connected with the conveying track 2. The driving assembly is used to provide a driving force to make the sliding assembly 11 slide on the conveying track 2. The driving assembly here is a prior art, usually using a motor. The lifting mechanism 3, the The telescopic mechanism 5 and the support assembly 4 are both installed on the trolley body 1. The trolley body 1 is the main supporting structure. The lifting mechanism 3 is arranged in the vertical direction of the trolley body 1, and is used to drive the support assembly 4 and the telescopic mechanism 5 to move as a whole along the vertical direction of the trolley body 1. Furthermore, the lifting mechanism 3 is connected to the support assembly 4, and the telescopic mechanism 5 is installed on the support assembly 4. The telescopic mechanism 5 is used to extend and retract to complete the removal of the material on the aging rack in the first position, and at the same time, the material is moved to the aging rack in the second position under the action of the sliding assembly 11 and the lifting mechanism 3.

[0022] Among them, the conveying track 2 is arranged along the loading and unloading direction of the aging room, and is usually laid along the straight line direction from the feed port to the discharge port of the aging room, so that the sliding component 11 cooperates with the conveying track 2 to move the trolley body 1 to the aging racks at different positions for loading and unloading operations, thereby realizing the automatic loading and unloading of materials on the aging racks in the entire aging room, and eliminating the need for manual wearing of protective equipment to enter the interior of the aging room to complete loading and unloading, thereby improving the aging capacity as a whole.

[0023] Specifically, the utility model uses the lifting mechanism 3 to make the telescopic mechanism 5 and the supporting assembly 4 move as a whole at different heights. The telescopic mechanism 5 and the supporting assembly 4 cooperate to remove the material from the aging rack and put it into another aging rack, thereby realizing the loading and unloading of materials at different heights, solving the inconvenience of the existing aging room relying on manual loading and unloading of aging racks with higher heights, and effectively improving the aging capacity and production efficiency.

[0024] In some embodiments, the lifting mechanism 3 includes a first driving member 31 and a first transmission member, the first driving member 31 is connected to the first transmission member, the first transmission member is connected to the support assembly 4, and the first driving member 31 provides a driving force to drive the transmission member to drive the support assembly 4 to move up and down.

[0025] In the specific example, the first driving member 31 is the existing technology, usually using a cylinder and a motor structure. When the first driving member 31 is the first motor, the first transmission member is a transmission lead screw or a transmission screw. The support assembly 4 is provided with a thread adapted to the transmission lead screw or the transmission screw. The first motor is started to drive the transmission lead screw to rotate, thereby causing the support assembly 4 to move up and down.

[0026] In another specific example, when the first driving member 31 is a first cylinder, the first transmission member is a first piston rod of the first cylinder, which is connected to the support assembly 4 through the first piston rod. After the first cylinder is started, the telescopic action of the first piston rod is utilized to drive the support assembly 4 connected thereto to move up and down, thereby realizing the loading and unloading of materials.

[0027] The first driving member 31 is fixedly mounted on the trolley body 1 , and the length direction of the transmission lead screw or the transmission screw is consistent with the vertical direction of the trolley body 1 .

[0028] The lifting mechanism 3 further includes a first auxiliary guide rail 33, and a first slider 45 is mounted on the support assembly 4, and the first slider 45 is slidably connected to the first auxiliary guide rail 33. By adding the first auxiliary guide rail 33 and the first slider 45, the stability of the up and down movement of the support assembly 4 is ensured, and no offset movement occurs under the driving action of the first driving member 31 and the first transmission member.

[0029] In a specific example, two sets of lifting mechanisms 3 are installed on the trolley body 1. Further, two sets of the first auxiliary guide rails 33 are installed on the trolley body 1. Correspondingly, each set of the first auxiliary guide rails 33 is provided with at least one or two first sliding blocks 45.

[0030] In some embodiments, the trolley body 1 is also provided with an upper limit block 101 and a lower limit block 102, the upper limit block 101 is used to locate the maximum position of the lifting mechanism 3 driving the support assembly 4 to move upward, and the lower limit block 102 is used to locate the maximum position of the lifting mechanism 3 driving the support assembly 4 to move downward.

[0031] In some embodiments, the support assembly 4 is mainly used to bear the weight of the telescopic mechanism 5 and the material together with the aging jig, while at the same time limiting the movement of the material on the telescopic mechanism 5 to prevent the material from moving or falling on the telescopic mechanism 5 when the trolley body 1 moves along the conveying track 2.

[0032] Specifically, the support assembly 4 includes a fixed frame 41, a left limit plate 42, a limit plate and a rear limit plate 44. The fixed frame 41 is fixedly installed on the trolley body 1, and the left limit plate 42 and the right limit plate 43 are relatively arranged. A telescopic space is formed between the left limit plate 42, the right limit plate 43 and the rear limit plate 44. The telescopic mechanism 5 is installed on the fixed frame 41 and is limited to be installed in the telescopic space. The telescopic space is also used to position the material removed from the aging rack. The rear limit plate 44 is arranged on the rear side of the fixed frame 41, that is, the rear side of the telescopic mechanism 5, to prevent the material from sliding from the rear side or to prevent the material driven by the telescopic mechanism 5 from exceeding the range of the telescopic space.

[0033] In addition, the left limit plate 42 and the right limit plate 43 also prevent the aging jig and materials from contacting the first auxiliary guide rail 33 of the lifting mechanism 3 and interfering with the movement of the lifting mechanism 3, thereby ensuring the reliability of the entire device.

[0034] In some embodiments, the telescopic mechanism 5 may be a multi-section telescopic structure, which is a prior art.

[0035] In some embodiments, the telescopic mechanism 5 includes a fixed arm 51, a second driving member, a second transmission member 32 and a support arm 52, the fixed arm 51 is slidably connected to the support arm 52, the second driving member is connected to the second transmission member 32, the second transmission member 32 is connected to the support arm 52, the fixed arm 51 is fixedly installed on the fixed frame 41, the second driving member is used to provide a driving force, driving the second transmission member 32 to drive the support arm 52 to slide relative to the fixed arm 51, so as to realize the extension and retraction of the support arm 52, so that when the trolley body 1 arrives at a certain aging rack, the support arm 52 extends out to drag the aging fixture and materials, and then cooperates with the lifting mechanism 3 to move the support assembly 4 and the telescopic mechanism 5 upward as a whole, so that the aging fixture and materials leave the aging rack, completing the unloading action.

[0036] In a specific example, a guide rack 53 is provided on the support arm 52, and the second driving member adopts a second motor here. A driving gear is installed on the output shaft of the second motor (the second transmission member 32), and the guide rack 53 is meshed and connected with a first guide gear 54. A transmission shaft is passed through the guide gear, and a second guide gear 55 is also connected to the transmission shaft. The second guide gear 55 is connected to the driving gear. After the second driving member is started, it drives the second transmission member 32 to rotate, thereby causing the guide gear to rotate. Under the cooperation of the guide rack 53 and the guide gear, the support arm 52 extends forward or retracts backward, and the driving gear is meshed and connected with the second guide gear 55, thereby providing power for the meshing transmission of the first guide gear 54 and the guide rack 53.

[0037] In another specific example, the guide rack 53 is meshedly connected with the first guide gear 54, and the first guide gear 54 is sleeved on the output shaft of the second motor. Thus, the first guide gear 54 is directly driven to rotate and mesh with the guide rack 53 through the rotation of the output shaft of the second motor.

[0038] When two sets of telescopic mechanisms 5 are provided on the fixed frame 41, the second motor can adopt a dual-output shaft motor, or adopt the driving structure of the above example, that is, two first guide gears 54 are provided on the transmission shaft, each of the first guide gears 54 is respectively meshed and connected with a guide rack 53 on a support arm 52, and a second guide gear 55 is also provided on the transmission shaft. A driving gear is installed on the output shaft of the second motor, and the driving gear is meshed and connected with the second guide gear 55, driving the second guide gear 55 to rotate, and then the transmission shaft and the first guide gear 54 rotate.

[0039] It should be noted that the position of the guide gear relative to the fixing frame 41 is fixed, and when the guide gear rotates, there is no motion interference with the second sliding block 57 .

[0040] In addition, the second driving member is a second motor, and a driving gear is installed on the second transmission member 32 (the output shaft of the second motor). The driving gear and the second guide gear 55 can also be connected by a belt or a chain.

[0041] In the above example, the telescopic mechanism 5 also includes a second auxiliary guide rail 56 and a second slider 57. The second auxiliary guide rail 56 is laid on the fixed arm 51, and the second slider 57 is installed on the support arm 52. The second slider 57 is slidably connected to the second auxiliary guide rail 56. Therefore, the second auxiliary guide rail 56 and the second slider 57 are used to ensure the stability of the telescopic mechanism 5 in driving the movement of materials and aging jigs.

[0042] In a specific example, in the driving structure that causes the support arm 52 to slide relative to the fixed arm 51, the second driving member can be a second cylinder, and the second transmission member 32 is the piston rod of the second cylinder. The piston rod of the second cylinder is connected to the support arm 52, and the support arm 52 is driven to extend and retract by the telescopic action of the piston rod.

[0043] In a specific example, at least two groups of the telescopic mechanisms 5 are provided on the fixing frame 41, and a plurality of groups of the telescopic mechanisms 5 are arranged side by side, thereby forming a plane for fixing the aging jig and materials, thereby ensuring the stability of loading and unloading.

[0044] Of course, only one set of telescopic mechanisms 5 is provided on the fixing frame 41, and a storage plate is installed on the supporting arm 52 for stably placing the aging jigs and materials.

[0045] The foregoing is merely a specific embodiment of the present invention, which enables those skilled in the art to understand or implement the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but rather to the widest scope consistent with the principles and novel features claimed herein.
