Description

Technical Field

[0001] The invention relates to the technical field of rail transportation, in particular to a double-layer rail transportation device. Background Art

[0002] Double-deck track transport devices usually refer to equipment with a double-deck track structure, which is used to improve transportation efficiency and space utilization. On industrial production lines, double-deck track transport devices can realize material transfer between different processes and reduce manual handling and waiting time. Double-deck track transport devices play an important role in modern logistics, industrial production, public transportation and other fields due to their unique structural characteristics and wide range of application scenarios.

[0003] According to the Chinese patent with the announcement number CN111824708B, a double-layer track transport device is disclosed. The invention has a double-layer track and can carry out three-dimensional double-layer track transport. A rectangular frame is provided on the upper and lower sides, and the track strip is divided into two layers, so that the transport vehicle can be transported on the two layers of track at the same time, thereby improving the utilization rate of space. The slide block and the plug board play a supporting role between the two rectangular frames;

[0004] The double-layer rail transport in the above technical solution uses two screws to rotate and drive two sliding plates and two enclosures to move away from or closer to each other, so that the placed objects can be restricted by the two enclosures. However, the restricted enclosures and sliding plates are both flat plate structures. This restriction can only produce a relatively stable clamping for square goods. For irregular stacking of goods, this clamping may not be in place. At the same time, the two sliding plates and two enclosures moving away from or closer to each other will block the space for taking the goods, which will hinder the taking and placing of the goods.

[0009] Preferably, a travel motor is installed in the middle part below the transport platform, and synchronous wheels are installed on the output shaft of the travel motor and the central shaft of the travel wheel. The synchronous wheels on the output shaft of the travel motor and the synchronous wheels on the central shaft of the travel wheel are connected by a synchronous belt.

[0010] Preferably, the outer side of the annular sleeve is equidistantly provided with latch teeth, and the equidistantly distributed latch teeth are located between two adjacent arms. A driving motor is also embedded and installed on the inner side of the transport platform, and the output end of the driving motor is provided with a driving gear that meshes with the latch teeth on the outer side of the annular sleeve.

[0011] Preferably, an inner cavity coaxial with the rotating groove is also opened in the middle of the upper side of the transport platform, and a connecting piece is docked in the inner cavity.

[0012] Preferably, the connecting piece is composed of an inner sleeve and an outer sleeve, and the lower edge of the inner sleeve of the connecting piece is in contact with the bottom wall of the inner cavity, and the upper edge of the outer sleeve of the connecting piece is in contact with the lower surface of the tray.

[0013] Preferably, a slope surface is provided at an equal angle on the lower edge of the extrusion and pushing member, a guide groove is longitudinally provided on the inner wall of the annular sleeve, and a sliding block sliding with the guide groove is longitudinally provided on the outer wall of the extrusion and pushing member.

[0014] Preferably, a sinking opening for the swing arm to rotate is provided at one end of the support arm close to the rotating shaft, and a blocking bar is also provided at one end of the support arm close to the sinking opening.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. The double-deck rail transport device is provided with a supporting mechanism, a clamping mechanism and a baffle linkage. By starting the driving motor to drive the driving gear to mesh with the outer teeth of the annular sleeve in both positive and negative directions, the annular sleeve drives the pallet on the extrusion and pushing member to move up and down. When the pallet is controlled to move down, the clamping mechanism drives the swing frame and the baffle to rotate and tighten, which is convenient for clamping and restricting different goods. When the pallet is controlled to move up, the clamping mechanism drives the swing frame and the baffle to rotate away from the pallet to facilitate the placement of goods. In addition, the synchronous lifting of the supporting mechanism facilitates personnel to directly take the goods without hindrance.

[0020] 2. For the double-deck track transport device, when the rotating annular sleeve drives the support arm to rotate forward, the support arm drives the swing arm to pull the baffle to tighten the clamping of the goods. When the limit pin at one end of the swing arm moves forward to the extreme position of the slide rail, the continuously rotating annular sleeve will produce a rotational misalignment with the swing arm through the sinking hole on the support arm, and the misaligned rotation of the support arm and the swing arm will cause the gas spring to be stretched. At the same time, the T-pin and the adjusting groove on the swing arm generate an elastic tightening force, which is convenient for the clamping mechanism to elastically tighten and limit the baffle, and can prevent the annular sleeve from driving the pallet to rotate excessively and causing the clamping mechanism and the baffle to clamp the goods excessively.

DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] See also Figure 1-Figure 10 The present invention provides a technical solution: a double-deck rail transport device, comprising a base 1, an I-rail 102 and a transport platform 2, support frames 101 are equidistantly installed on both sides of the base 1, I-rails 102 are symmetrically installed on both sides of the top of the base 1 and the support frame 101, a transport platform 2 is arranged on the I-rail 102, a travel wheel 201 rollingly overlapped with the I-rail 102 is installed on the lower side of the transport platform 2 through a bearing, a travel motor 202 is installed in the middle below the transport platform 2, a synchronous wheel 203 is installed on the output shaft of the travel motor 202 and the central shaft of the travel wheel 201, and the synchronous wheel 203 on the output shaft of the travel motor 202 and the synchronous wheel 203 on the central shaft of the travel wheel 201 are connected by a synchronous belt 204;

[0035] A supporting mechanism 5 is provided on the upper side of the transport platform 2. The supporting mechanism 5 includes a rotating groove 504 opened on the upper surface of the transport platform 2. A ring sleeve 501 is rotated on the middle outer ring of the rotating groove 504 through a bearing. A ramp block 505 is also welded to the middle inner ring of the rotating groove 504. A pushing piece 502 is abutted on the upper side of the ramp block 505. A tray 506 is fixed on the top of the pushing piece 502.

[0036] A clamping mechanism 6 is arranged on the outer side of the annular sleeve 501. The clamping mechanism 6 includes a support arm 601 fixed to the outer wall of the annular sleeve 501. One end of the support arm 601 is connected to a swing arm 602 through a rotating shaft. An adjusting groove 603 is provided on the surface of the swing arm 602. One end of the swing arm 602 away from the support arm 601 is slidably connected to a slide rail 605 through a limit pin. The slide rail 605 is fixed to a side surface of a baffle 7. One end of the baffle 7 is rotatably connected above the transport platform 2. The baffles 7 are arranged in no less than three groups, and no less than three groups of baffles 7 are distributed at equal angles on the outer side of the pallet 506. By arranging no less than three groups of baffles 7 on the outer side of the pallet 506, it is convenient to clamp and restrict different types of goods on the pallet 506.

[0037] A sliding groove 701 is transversely provided on the surface of the baffle 7, and a rack rod 606 is slidably connected in the middle of the sliding groove 701. One end of the rack rod 606 is placed on the slide rail 605, and the rack rod 606 is movably connected to a limit pin at one end of the swing arm 602. A rotating cavity 702 is provided on one side surface of the baffle 7, and a swing frame 607 is rotatably connected in the middle of the rotating cavity 702. A transmission gear disc 608 meshing with the rack rod 606 is fixed at the lower end of the swing frame 607. The swing frame 607 is a "D"-shaped structure. A side block for limiting the rotation angle of the swing frame 607 is provided on the side of the baffle 7 close to the swing frame 607. By providing the side block, the swing frame 607 can be blocked and restricted when it rotates to a surface that does not fit the baffle 7, ensuring that the swing frame 607 has a maximum rotation limit.

[0038] The outer side of the annular sleeve 501 is equidistantly provided with latch teeth, and the equidistantly distributed latch teeth are located between two adjacent arms 601. The inner side of the transport platform 2 is also embedded with a drive motor 3, and the output end of the drive motor 3 is provided with a drive gear 301 that meshes with the latch teeth on the outer side of the annular sleeve 501. The middle part of the upper side of the transport platform 2 is also provided with an inner cavity coaxial with the rotating groove 504, and a connector 4 is docked in the inner cavity.

[0039] The connecting member 4 is composed of an inner sleeve and an outer sleeve, and the lower edge of the inner sleeve of the connecting member 4 is in contact with the bottom wall of the inner cavity, and the upper edge of the outer sleeve of the connecting member 4 is in contact with the lower surface of the tray 506. When the annular sleeve 501 rotates forward and reversely, the pushing member 502 will slide forward and reversely along the ramp block 505, so that the pushing member 502 will drive the tray 506 to move up and down. When the tray 506 moves up and down, the inner sleeve and the outer sleeve of the connecting member 4 cooperate to achieve a telescopic connection, so that the lifting height of the tray 506 is limited by the telescopic length of the connecting member 4, and the pushing member 502 can be prevented from detaching from the annular sleeve 501.

[0040] A slope surface 503 is provided at an equal angle on the lower edge of the pushing piece 502. The pushing piece 502 and the slope block 505 are both arc-shaped structures. The inclination angle of the slope surface 503 is the same as the inclination angle of the slope block 505, so that the pushing piece 502 can be rotated and slid along the upper surface of the slope block 505 to be lifted or rotated and slid down during rotation. A guide groove is longitudinally provided on the inner wall of the annular sleeve 501, and a sliding block that slides with the guide groove is longitudinally provided on the outer wall of the pushing piece 502. By setting the sliding block and the guide groove for linear sliding, the pushing piece 502 can slide up and down in the annular sleeve 501.

[0041] In specific implementation, the driving motor 3 is started to rotate forward to drive the driving gear 301 to mesh with the outer teeth of the annular sleeve 501, so that the annular sleeve 501 rotates in the opposite direction to the driving gear 301. At this time, the reverse rotation of the annular sleeve 501 drives the pushing member 502 to rotate in the opposite direction. At this time, the pushing member 502 squeezes the slope block 505 in the rotating groove 504 through the slope surface 503 at the lower edge, so that the pushing member 502 rotates and rises along the slope block 505. When the pushing member 502 is lifted, it drives the top tray 506 to move upward;

[0042] When the annular sleeve 501 drives the pushing member 502 to rotate in the opposite direction, the annular sleeve 501 will rotate in the opposite direction through the outer support arm 601 and the swing arm 602, so that the swing arm 602 slides in the opposite direction along the slide rail 605 on the side of the baffle 7 through the limit pin at one end, so that the swing arm 602 squeezes the slide rail 605 through the limit pin, so that the baffle 7 rotates in the upper direction of the transport platform 2 away from the pallet 506; and when the limit pin at one end of the swing arm 602 slides in the opposite direction along the slide rail 605 on the side of the baffle 7, the swing arm 602 will drive the rack rod 606 to slide in the opposite direction along the slide groove 701 on the surface of the baffle plate 7. At this time, the rack rod 606 moving in the opposite direction will mesh with the transmission gear plate 608 in the rotating cavity 702, thereby driving the transmission gear plate 608 to drive the swing frame 607 to rotate toward the surface of the baffle plate 7, so that the swing frame 607 moves away from the pallet 506 following the baffle plate 7, so that the pallet 506 lifted by the jacking and the baffle plate 7 rotated outwards can be conveniently placed on the pallet 506 for transport;

[0043] On the contrary, when the pallet 506 on the transport platform 2 is loaded with goods, the drive motor 3 is started to reversely rotate to drive the drive gear 301 to engage with the outer teeth of the annular sleeve 501 in the reverse direction, and the annular sleeve 501 generates a reverse rotation in the opposite direction to the drive gear 301. At this time, the forward rotation of the annular sleeve 501 drives the pushing member 502 to slide along the upper surface of the slope block 505 through the slope surface 503 at the lower edge. Under the action of the gravity of the pallet 506 and the goods, the pushing member 502 moves along the slope block 505. The ramp block 505 rotates and moves downward, and the pushing member 502 drives the top tray 506 to move downward when it descends; at the same time, when the annular sleeve 501 drives the support arm 601 and the swing arm 602 to rotate forward, the swing arm 602 will slide forward along the slide rail 605 on the side of the baffle 7 through the limit pin at one end, so that the swing arm 602 will drive the baffle 7 to rotate in the direction of approaching the tray 506 in the upper direction of the transport platform 2 by pulling the slide rail 605, and the swing arm 602 will drive the rack rod 606 along the baffle The slide groove 701 on the surface of the tray 506 slides forward, and the rack rod 606 moving forward at this time drives the swing frame 607 on the transmission gear disc 608 to rotate in a direction perpendicular to the baffle 7, so that the swing frame 607 follows the baffle 7 to move in the direction close to the tray 506. At this time, the descending tray 506 and the baffle 7 rotated inward to tighten the tray 506 facilitate the positioning and clamping of the goods placed on the tray 506, and the baffle 7 can limit the goods through the swing frame 607 on the side. A plurality of rotatable swing frames 607 are arranged on one side of the baffle 7, and the swing frames 607 can effectively squeeze and clamp irregular goods; when the transport device transports the goods to the designated position and needs to take out the goods, the goods can be lifted upward by controlling the tray 506 to rise, and at the same time, the baffle 7 and the swing frame 607 are driven away from the goods to lose the clamping restriction, and the tray 506 can drive the goods to rotate by rotating and rising, so as to facilitate the direct picking of the goods and prevent the goods from being blocked by the baffle 7 when taking them.

[0044] See also Figure 7-Figure 9 A sinking opening for the swing arm 602 to rotate is provided at one end of the support arm 601 close to the rotating shaft, and a blocking bar is also provided at one end of the support arm 601 close to the sinking opening; a gas spring 604 is movably connected below the blocking bar, and a T-shaped pin docking with the adjusting slot 603 is connected to the output end of the gas spring 604.

[0045] In specific implementation, when the rotating annular sleeve 501 drives the support arm 601 and the swing arm 602 to reverse, the support arm 601 will squeeze the swing arm 602 through the blocking bar at one end, so that the swing arm 602 moves in the opposite direction along the slide rail 605 through the limit pin at the end. At this time, the movable connection between the support arm 601 and the swing arm 602 is limited by the blocking bar, which can prevent the swing arm 602 from rotating through the rotating shaft;

[0046] When the rotating annular sleeve 501 drives the support arm 601 to rotate forward, the blocking bar at one end of the support arm 601 is at the front side of the rotation of the swing arm 602, and the T-pin at one end of the gas spring 604 moves from the end of the adjusting slot 603 away from the rotating shaft to the end of the adjusting slot 603 close to the rotating shaft. In this process, the swing arm 602 rotates around the limit pin as the axis, so that the support arm 601 and the swing arm 602 are misaligned at a small angle. When the T-pin at one end of the gas spring 604 abuts against the end of the adjusting slot 603 close to the rotating shaft, the support arm 601 that continues to rotate forward will traction the swing arm 602, so that the swing arm 602 can be pulled and moved along As the slide rail 605 moves forward, when the limit pin at one end of the swing arm 602 moves forward to the extreme position of the slide rail 605, the continuously rotating annular sleeve 501 will produce a rotational misalignment with the swing arm 602 through the sinking hole on the support arm 601, and the misaligned rotation of the support arm 601 and the swing arm 602 will cause the gas spring 604 to be stretched. At the same time, the T-pin and the adjustment groove 603 on the swing arm 602 generate an elastic tightening force, which facilitates the elastic tightening and limiting of the baffle 7 by the clamping mechanism 6, and can prevent the annular sleeve 501 from driving the pallet 506 to rotate excessively and causing the clamping mechanism 6 and the baffle 7 to clamp the goods excessively.

[0047] See also Fig. 9 and Fig.11 The transmission gear disc 608 is rotatably connected in the rotating cavity 702. Two sets of receiving cavities are opened on the outer peripheral side of the transmission gear disc 608. A return spring 609 is connected to the receiving cavity of the transmission gear disc 608. One end of the return spring 609 is connected to a tooth block 610 that slides with the receiving cavity.

[0048] In specific implementation, when the swing frame 607 is horizontally pressed against the side of the baffle 7, the rotating swing arm 602 moves forward along the slide rail 605 through the limit pin at one end to drive the rack rod 606 to move along the slide groove 701, and the rack rod 606 will mesh with the first group of tooth blocks 610 on the transmission gear plate 608. When the transmission gear plate 608 is meshed and rotated by a certain angle, the second group of tooth blocks 610 will mesh with the rack rod 606. At this time, the swing frame 607 on the transmission gear plate 608 will abut against the side block on the surface of the baffle 7 without continuing to rotate, and at this time, the rack rod 606 will continue to slide along the slide groove 701 under the traction of the swing arm 602. In this process, the second group of tooth blocks 610 will mesh with the rack rod 606. The tooth block 610 will squeeze the reset spring 609 along the storage cavity in the middle of the transmission gear plate 608 to ensure that the rack rod 606 can continue to move without being restricted by the transmission gear plate 608; on the contrary, when the swing frame 607 is against the side block abutting against the surface of the baffle 7, the rotating swing arm 602 moves in the opposite direction along the slide rail 605 through the limit pin at one end to drive the rack rod 606 to move along the slide groove 701, and the transmission gear plate 608 will rotate in the opposite direction to pull open and drive the swing frame 607 to rotate in the opposite direction. Through the elastic sliding arrangement of the transmission gear plate 608 and the tooth block 610, the transmission gear plate 608 will not hinder the movement restriction of the rack rod 606 when it rotates to the extreme position.

[0049] To summarize, by starting the travel motor 202 to drive the synchronous wheel 203 on the output shaft to operate, the travel motor 202 drives the travel wheel 201 to roll on the I-rail 102 through the transmission of the synchronous wheel 203 and the synchronous belt 204, so that the two groups of transport platforms 2 can respectively travel on the I-rail 102 of the base 1 and the support frame 101, thereby performing double-layer track transportation along the two groups of I-rails 102 through the two groups of transport platforms 2, which facilitates improving the utilization rate of space and can classify and transport different goods transported to the same location.
