Description

Technical Field

[0001] The utility model relates to the field of multi-functional shelf driving devices, in particular to a multi-functional shelf driving device for a cargo loading device. Background Art

[0002] The automatic loading device includes a gantry that can move between goods and a carriage, and a shelf that can be lifted and swung inside the gantry. The specific process of loading goods is as follows: after the shelf swings downward to drive the fork rack to swing downward, the gantry moves to insert the fork rack of the shelf onto the corresponding goods pallet, and then the shelf swings upward and rises to lift the goods. Subsequently, when the gantry moves the goods to the corresponding position inside the carriage, after the shelf descends and swings downward, the gantry moves to separate the goods from the fork rack, so as to effectively lift and load and unload the goods.

[0003] However, the lifting and swinging of the shelf of the existing automatic loading device need to be driven by two sets of driving structures respectively, resulting in an increase in driving costs. Moreover, the weights of the shelf and the goods are supported by the lifting of the oil cylinder telescopic rod of the swinging driving structure, which easily damages the swinging driving structure and has a high maintenance cost.

[0004] Designing a multi-functional shelf driving device for a cargo loading device to solve the problems existing in the above-mentioned prior art is the purpose of the research of the present utility model. Content of the Utility Model

[0005] In view of the problems existing in the above-mentioned prior art, the present utility model provides a multi-functional shelf driving device for a cargo loading device, which can effectively solve the problems existing in the above-mentioned prior art.

[0006] The technical solution of the present utility model is as follows:

[0007] A multi-functional shelf driving device for a cargo loading device includes:

[0008] A lifting driving mechanism;

[0009] A connecting member, with both ends respectively rotatably connected to a first linkage mechanism and a second linkage mechanism. The first linkage mechanism and the second linkage mechanism are respectively driven by the lifting driving mechanism to move up and down. The lifting driving mechanism is used to drive the first linkage mechanism and the second linkage mechanism to move in the same direction to drive the connecting member to move up and down, or drive the first linkage mechanism and the second linkage mechanism to move in opposite directions or one of them to move, so as to drive the connecting member to swing to an inclined position.

[0010] Furthermore, the lifting drive mechanism includes a fixed frame installed above the connecting member, and a lifting electric cylinder fixedly installed inside the fixed frame in a front-back distribution. The first linkage mechanism and the second linkage mechanism have the same structure and are symmetrically arranged. The first linkage mechanism includes several telescopic frames that are slidably sleeved and linked telescopically from top to bottom in sequence. The highest-level telescopic frame is slidably sleeved with the fixed frame and is respectively connected to the telescopic rods of the corresponding lifting electric cylinders. The lowest-level telescopic frames of the first linkage mechanism and the second linkage mechanism are respectively hinged to the front and rear ends of the connecting member.

[0011] Furthermore, the connecting member is a horizontally arranged frame structure. The several telescopic frames are, from top to bottom, a first-level frame, a second-level frame, and a third-level frame. The left and right outer sides of the first-level frame, the second-level frame, and the third-level frame are respectively slidably connected to the left and right inner sides of the fixed frame, the first-level frame, and the second-level frame through guide sliders and guide rails. The corresponding telescopic rods are respectively connected to the middle sides of the first-level frames of the first linkage mechanism and the second linkage mechanism. The left and right lower ends of the third-level frames of the first linkage mechanism and the second linkage mechanism are respectively hinged to the left and right sides of the front and rear tops of the connecting member to form a four-corner connection.

[0012] Furthermore, reinforcing plates are respectively detachably installed on the front and rear tops of the connecting member. The left and right lower ends of the third-level frames of the first linkage mechanism and the second linkage mechanism are respectively hinged to the left and right ends of the two reinforcing plates.

[0013] Furthermore, the first linkage mechanism further includes a first-level linkage assembly. The first-level linkage assembly includes several first-level sprockets rotatably installed on the upper part of the first-level frame, and a first-level chain that respectively passes around the several first-level sprockets and has one end connected to the lower part of the second-level frame. The several first-level sprockets are higher than the lower end of the fixed frame, and the other ends of the several first-level chains are fixedly connected to the lower end of the fixed frame.

[0014] Furthermore, the first linkage mechanism further includes a second-level linkage assembly. The second-level linkage assembly includes several second-level sprockets rotatably installed on the upper part of the second-level frame, and a second-level chain that respectively passes around the several second-level sprockets and has one end connected to the lower part of the third-level frame. The several second-level sprockets are higher than the lower end of the first-level frame, and the other ends of the several second-level chains are fixedly connected to the lower end of the first-level frame.

[0015] Therefore, the present utility model provides the following effects and / or advantages:

[0016] 1. By adding the first linkage mechanism and the second linkage mechanism, the lifting drive mechanism can not only drive the connecting piece and the shelf to lift and lower smoothly, but also, when the shelf holds and transports goods into the carriage and is about to unload, or after the shelf inserts and takes goods, drive the connecting piece and the shelf to swing to an inclined position, so that the goods slide down obliquely into the carriage to meet the loading requirement of tight fitting between goods, or make the goods move inwards obliquely on the shelf to improve the stability of the shelf holding and transporting. Thus, without adding a new drive structure, by adding the first linkage mechanism and the second linkage mechanism, the multi-functional drive of the lifting drive mechanism is realized to reduce the drive cost, and the weights of the connecting piece, the rotary drive mechanism and the shelf are dispersed and conducted to the lifting drive mechanism through the first linkage mechanism and the second linkage mechanism, avoiding the concentrated force on the lifting drive mechanism, improving the drive stability and prolonging the service life of the drive mechanism.

[0017] 2. By arranging the first linkage mechanism and the second linkage mechanism as several telescopic frames that are sleeved and linked telescopically in a step-by-step manner from top to bottom, the connection points at the upper and lower ends of the lifting electric cylinder are shortened from between the fixed frame and the connecting piece to between the fixed frame and the highest-level telescopic frame. Thus, on the premise of ensuring the up-and-down lifting stroke of the connecting piece driven by the first linkage mechanism and the second linkage mechanism, the length of the telescopic rod of the required lifting electric cylinder is greatly shortened, the overall length of the lifting electric cylinder is shortened, and further, the vertical structural compactness of the first linkage mechanism and the second linkage mechanism is improved, and the overall height of the multi-functional shelf drive device is further reduced; at the same time, the rotary drive mechanism is arranged in the middle of the connecting piece, which can improve the balance of force between the first linkage mechanism and the second linkage mechanism, further improve the stability of the connecting piece suspended below the transverse movement frame, and the stability of the first linkage mechanism and the second linkage mechanism driving the connecting piece to lift or tilt.

[0018] 3. By respectively hinging the four corners of the connecting piece with the two or three-level frames, the connection strength between the two is improved, and further, the stability of the connecting piece suspended in the transverse movement frame is improved, and further, excessive shaking of the connecting piece during the rotation of the shelf driven by the drive mechanism is avoided. And through the guide sliders and guide rails between the fixed frame, the first-level frame, the second-level frame and the third-level frame for multi-level overlapping guidance, four-side vertical stable and high-precision guidance is realized, ensuring the stability of the first linkage mechanism and the second linkage mechanism driving the connecting piece and the shelf to lift and lower and swing to an inclined position. Especially, the situation of relative skew between the first-level frame, the second-level frame and the third-level frame of the first linkage mechanism and the second linkage mechanism resulting in structural damage when the connecting piece and the shelf swing to an inclined position is avoided, improving the stability and reliability of the multi-functional shelf drive device.

[0019] 4. By installing the first-stage sprocket and the second-stage sprocket at the high positions of the first-stage frame and the second-stage frame, and connecting one end of the chain and the second-stage chain to the low positions of the second-stage frame and the third-stage frame, the linkage telescopic stroke of the second-stage frame and the third-stage frame is increased, and a larger range of lifting stroke is achieved on the premise that the lengths of the second-stage frame and the third-stage frame are the same.

[0027] For the convenience of those skilled in the art to understand, the structure of the present invention will be further described in detail below in conjunction with the accompanying drawings:

[0028] Reference Figure 1-6 , a multi-functional shelf driving device for a goods loading device, the goods loading device includes: a transverse movement frame 1 driven to move transversely by a transverse movement driving mechanism 2; specifically, the transverse movement driving mechanism 2 includes two parallel ground rails 21 and a walking frame 22 driven by a motor to move transversely on the ground rails 21, and the left and right ends of the transverse movement frame 1 are supported on the walking frame 22 through columns to form a gantry frame. The transverse movement driving mechanism 2 drives the transverse movement frame 1 to move transversely between the vehicle and the goods. The specific structure of the transverse movement driving mechanism 2 is the prior art and not the main inventive point of this application, so it will not be elaborated here;

[0029] The multi-functional shelf driving device includes:

[0030] a lifting driving mechanism 3;

[0031] The connecting member 4 is rotatably connected to the first linkage mechanism 6 and the second linkage mechanism 7 at both ends respectively. The first linkage mechanism 6 and the second linkage mechanism 7 are respectively driven by the lifting drive mechanism 3 to move up and down. The connecting member 4 is used for connecting the corresponding shelves in a linkage manner, and the shelf 8 is used for horizontally inserting and taking the corresponding goods; the lifting drive mechanism 3 is used to drive the first linkage mechanism 6 and the second linkage mechanism 7 to move in the same direction to drive the connecting member 4 to move up and down, or to drive the first linkage mechanism 6 and the second linkage mechanism 7 to move in opposite directions or one of them to move, so as to drive the connecting member 4 to swing to an inclined position.

[0032] With the above structure, by adding the first linkage mechanism 6 and the second linkage mechanism 7, the lifting drive mechanism 3 can not only drive the connecting member 4 and the shelf 8 to move up and down smoothly, but also when the shelf 8 is about to unload the goods carried to the carriage after lifting and transporting the goods, or after the shelf 8 inserts the goods, drive the connecting member 4 and the shelf 8 to swing to an inclined position, so that the goods slide down obliquely to the carriage to meet the loading requirement of the goods being closely attached to each other, or make the goods move inwards obliquely on the shelf 8 to improve the stability of the shelf 8 in lifting and transporting. Therefore, without adding a new drive structure, by adding the first linkage mechanism 6 and the second linkage mechanism 7, the multi-functional drive of the lifting drive mechanism 3 is realized to reduce the drive cost, and the weights of the connecting member 4, the rotary drive mechanism 5 and the shelf 8 are dispersed and conducted to the lifting drive mechanism 3 through the first linkage mechanism 6 and the second linkage mechanism 7, avoiding the concentrated force on the lifting drive mechanism 3, improving the drive stability and prolonging the service life of the drive mechanism.

[0033] In order to reduce the overall height of the driving device of the multi-functional shelf, the lifting driving mechanism 3 includes a fixed frame 31 disposed above the connecting member 4, and lifting electric cylinders 32 fixedly arranged in the fixed frame 31 in the front and rear distribution. Specifically, the fixed frame 31 is fixedly arranged inside the transverse moving frame 1, and the connecting member 4 is suspended below the transverse moving frame 1 through a first linkage mechanism 6 and a second linkage mechanism 7. A rotation driving mechanism 5 for driving the shelf 8 to rotate horizontally can be arranged on the connecting member 4. The first linkage mechanism 6 and the second linkage mechanism 7 have the same structure and are symmetrically arranged. The first linkage mechanism 6 includes a plurality of telescopic frames that are slidably sleeved and linked to expand and contract step by step from top to bottom. The highest-level telescopic frame is slidably sleeved with the fixed frame 31 and is respectively connected to the telescopic rods 321 of the corresponding lifting electric cylinders 32. The lowest-level telescopic frames of the first linkage mechanism 6 and the second linkage mechanism 7 are respectively hinged to the front and rear ends of the connecting member 4. By arranging the first linkage mechanism 6 and the second linkage mechanism 7 with a plurality of telescopic frames that are slidably sleeved and linked to expand and contract step by step from top to bottom, the connection points at the upper and lower ends of the lifting electric cylinder 32 are shortened from between the fixed frame 31 and the connecting member 4 to between the fixed frame 31 and the highest-level telescopic frame, so as to ensure that the first linkage mechanism 6 and the second linkage mechanism 7 drive the connecting member 4 to move up and down, and greatly shorten the length of the telescopic rod 321 of the required lifting electric cylinder 32, shorten the overall length of the lifting electric cylinder 32, and further improve the vertical structural compactness of the first linkage mechanism 6 and the second linkage mechanism 7, and further reduce the overall height of the driving device of the multi-functional shelf; at the same time, by arranging the rotation driving mechanism 5 in the middle of the connecting member 4, the balance of the force between the first linkage mechanism 6 and the second linkage mechanism 7 can be improved, the stability of the connecting member 4 suspended below the transverse moving frame 1 can be further improved, and the stability of the first linkage mechanism 6 and the second linkage mechanism 7 driving the connecting member 4 to lift or tilt can be improved.

[0034] In order to further improve the lifting and tilting stability of the connecting member 4 and the shelf 8, the connecting member 4 is a horizontally arranged frame structure. The several levels of the telescopic frames are successively the first-level frame 61, the second-level frame 62, and the third-level frame 63 from top to bottom. The left and right outer sides of the first-level frame 61, the second-level frame 62, and the third-level frame 63 are respectively connected to the left and right inner sides of the fixed frame 31, the first-level frame 61, and the second-level frame 62 through guiding sliders 64 and guide rails 65 for up and down sliding connection. Specifically, guide rails 65 are respectively fixedly provided on the left and right outer sides of the first-level frame 61, the second-level frame 62, and the third-level frame 63, and several guiding sliders 64 that are slidably arranged with the corresponding guide rails 65 are respectively fixedly provided on the left and right inner sides of the fixed frame 31, the first-level frame 61, and the second-level frame 62. In other embodiments, up and down sliding connection can also be achieved through guide rails 65 and rollers. The corresponding telescopic rods 321 are respectively connected to the middle sides of the first-level frame 61 of the first linkage mechanism 6 and the second linkage mechanism 7. The left and right lower ends of the third-level frame 63 of the first linkage mechanism 6 and the second linkage mechanism 7 are respectively hinged to the left and right sides of the front and rear tops of the connecting member 4 to form a four-corner connection. Thus, by respectively hinging the two third-level frames 63 to the four corners of the connecting member 4, the connection strength between the two is improved, and further, the stability of the connecting member 4 suspended in the transverse moving frame 1 is improved. Further, excessive shaking of the connecting member 4 during the rotation of the shelf 8 driven by the driving mechanism is avoided, and multi-level overlapping guiding is carried out through the guiding sliders 64 and guide rails 65 between the fixed frame 31, the first-level frame 61, the second-level frame 62, and the third-level frame 63 to achieve four-side vertical stable and high-precision guiding, ensuring the stability of the first linkage mechanism 6 and the second linkage mechanism 7 driving the connecting member 4 and the shelf 8 to move up and down and swing to an inclined setting. In particular, the situation where the first-level frame 61, the second-level frame 62, and the third-level frame 63 of the first linkage mechanism 6 and the second linkage mechanism 7 are relatively skewed when the connecting member 4 and the shelf 8 swing to an inclined setting, resulting in structural damage, is avoided, and the stability and reliability of the multi-functional shelf driving device are improved.

[0035] In order to improve the connection strength between the third-level frame 63 and the connecting member 4, reinforcing plates 41 are respectively detachably provided at the front and rear tops of the connecting member 4, and the left and right lower ends of the third-level frame 63 of the first linkage mechanism 6 and the second linkage mechanism 7 are respectively hinged to the left and right ends of the two reinforcing plates 41.

[0036] In order to realize the linkage telescoping between the first-stage frame 61, the second-stage frame 62, and the third-stage frame 63 while extending the telescoping stroke to increase the lifting stroke, the first linkage mechanism 6 further includes a first-stage linkage assembly 66. The first-stage linkage assembly 66 includes a plurality of first-stage sprockets 661 rotatably provided on the upper part of the first-stage frame 61, and a first-stage chain 662 that respectively passes around the plurality of first-stage sprockets 661 and has one end connected to the lower part of the second-stage frame 62. The plurality of first-stage sprockets 661 are higher than the lower end of the fixed frame 31, and the other ends of the plurality of first-stage chains 662 are fixedly connected to the lower end of the fixed frame 31. The first linkage mechanism 6 further includes a second-stage linkage assembly 67. The second-stage linkage assembly 67 includes a plurality of second-stage sprockets 671 rotatably provided on the upper part of the second-stage frame 62, and a second-stage chain 672 that respectively passes around the plurality of second-stage sprockets 671 and has one end connected to the lower part of the third-stage frame 63. The plurality of second-stage sprockets 671 are higher than the lower end of the first-stage frame 61, and the other ends of the plurality of second-stage chains 672 are fixedly connected to the lower end of the first-stage frame 61. When the lifting electric cylinder 32 drives the first-stage frame 61 and the plurality of first-stage sprockets 661 to rise, the second-stage frame 62 and the plurality of second-stage sprockets 671 are lifted through the plurality of first-stage chains 662 and gradually retracted into the first-stage frame 61. At the same time, the second-stage frame 62 lifts the third-stage frame 63 through the plurality of second-stage chains 672 and gradually retracts it into the second-stage frame 62. When the lifting electric cylinder 32 drives the first-stage frame 61 and the plurality of first-stage sprockets 661 to descend, the second-stage frame 62 and the plurality of second-stage sprockets 671 are lowered through the plurality of first-stage chains 662 and gradually extend downward. At the same time, the second-stage frame 62 lowers the third-stage frame 63 through the plurality of second-stage chains 672 and gradually extends downward, thereby realizing the linkage telescoping between the first-stage frame 61, the second-stage frame 62, and the third-stage frame 63. On this basis, by installing the first-stage sprockets 661 and the second-stage sprockets 671 at high positions on the first-stage frame 61 and the second-stage frame 62, and connecting one ends of the chain and the second-stage chain 672 to low positions on the second-stage frame 62 and the third-stage frame 63, the linkage telescoping stroke of the second-stage frame 62 and the third-stage frame 63 is increased, and a larger range of lifting stroke is realized on the premise that the lengths of the second-stage frame 62 and the third-stage frame 63 are the same.

[0037] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
