Description

Technical Field

[0001] This invention relates to a shuttle track, and more particularly to a concealed, height-adjustable shuttle track structure and its construction method. Background Technology

[0002] Shuttle trolleys are a common piece of equipment in automated warehousing, primarily used in environments where multiple conveyor lines connect to workstations on both sides. Compared to conveyor lines, they offer advantages such as lower cost and lower energy consumption. With the continuous development of industrial automation, the use of AGVs (Automated Guided Vehicles) is increasing. To achieve automatic docking between the conveyor system and the AGV, the overall height of the shuttle trolley needs to be continuously reduced. Lowering the height of the shuttle track has become a very effective design solution. Currently, the commonly used shuttle track structure involves setting a supporting steel plate at the bottom of an I-beam track, fixing the I-beam track to the top surface of the supporting steel plate, and installing supporting anchor bolts between the supporting steel plate and the concrete foundation. The nuts on the anchor bolts are used to adjust the height of the support steel plates, thereby adjusting the height of the shuttle car track. This existing shuttle car track support structure has the following problems: (1) The anchor bolts are set on both sides of the I-shaped track, which results in a limited range of height adjustment of the support steel plates, directly resulting in a limited range of height reduction for the shuttle car track that requires adjustable height; (2) Since the upper part of the anchor bolts is set above the top surface of the support steel plates on both sides of the I-shaped track, it causes interference defects with the installation of the shuttle car sliding contact line and the setting of the positioning barcode. Designing a shuttle car track structure that facilitates the installation of the shuttle car power supply sliding contact line and positioning barcode, and can effectively reduce the track height, has become a problem that needs to be solved on site. Summary of the Invention

[0003] This invention provides a shuttle track with a hidden height adjustment mechanism, which can effectively reduce the track height and facilitate the installation of the shuttle's power supply sliding contact line and positioning barcode.

[0004] The present invention solves the above technical problems through the following technical solutions: A shuttle track structure with a concealed height adjustment mechanism includes a concrete foundation slab and an I-beam track. Vertical embedded sleeves and anchor bolts are respectively installed on the concrete foundation slab. A ground support steel plate is installed on the top end of the vertical embedded sleeve, and the ground support steel plate is fixed to the ground above the top end of the vertical embedded sleeve by anchor bolts. A screw head embedding groove is provided on the bottom surface of the I-beam track, and the screw head of the height adjustment bolt is movably disposed in the screw head embedding groove. The ground support steel plate is located above the top end of the vertical embedded sleeve. The support steel plate has a threaded through hole. An Ω-shaped flange is movably fitted onto the height adjustment bolt below the bolt head. The tail end of the bolt of the height adjustment bolt is screwed into the threaded through hole. A bolt passes through the through hole in the middle of the Ω-shaped flange. The Ω-shaped flange is movably fitted onto the height adjustment bolt by the bolt passing through the through hole. A wrench-locked hexagonal head is fixedly installed on the height adjustment bolt below the bolt passing through the through hole. A lock nut is screwed onto the height adjustment bolt between the wrench-locked hexagonal head and the ground support steel plate.

[0005] The Ω-shaped flange is fixed to the bottom surface of the I-shaped rail by flange fixing bolts.

[0006] A shuttle car is installed on the I-shaped track. A sliding contact line power supply mechanism and a positioning code reading mechanism are installed on the shuttle car. A sliding contact line is installed on the outer surface of the web of the I-shaped track on one side of the shuttle car. The sliding contact line and the sliding contact line power supply mechanism are in contact. A positioning barcode is installed on the outer surface of the web of the I-shaped track on the other side of the shuttle car. The positioning barcode and the positioning code reading mechanism are set accordingly.

[0007] A method for constructing a shuttle track with a concealed height adjustment mechanism, characterized by the following steps: The first step is to embed the vertical pre-embedded sleeves into the concrete when pouring the concrete foundation slab for the shuttle car. The second step is to machine a screw head embedding groove on the bottom surface of the I-shaped track, and then insert the screw head of the height adjustment bolt into the screw head embedding groove so that the height adjustment bolt is movably suspended on the bottom surface of the I-shaped track. The third step is to process a through hole with internal thread on the ground support steel plate, fix the ground support steel plate to the concrete foundation plate with anchor bolts, and set the through hole with internal thread on the top end of the vertical pre-embedded sleeve. Step 4: Machining an Ω-shaped flange, machining a through hole for the bolt in the middle of the Ω-shaped flange, fitting the Ω-shaped flange onto the height adjusting bolt, and fixing it to the bottom surface of the I-shaped rail with flange fixing bolts; installing a wrench-fitting hexagonal head on the height adjusting bolt below the through hole, fixing the wrench-fitting hexagonal head to the height adjusting bolt as one piece, and screwing a lock nut onto the height adjusting bolt below the wrench-fitting hexagonal head; Step 5: Place the connected I-beam track, Ω-shaped flange, and height adjustment bolt above the ground support steel plate. Then, mate the tail end of the height adjustment bolt into the threaded through hole, engage the wrench with the wrench holder hexagonal head, and rotate the height adjustment bolt by wrench to adjust the height of the I-beam track. Step 6: After the I-beam track is adjusted to the designed height, tighten the height adjustment bolts to the ground support steel plate by tightening the lock nuts.

[0008] This invention effectively supports the shuttle track while allowing for flexible height adjustment of the track by adjusting the support screw downwards. At the same time, the adjusting screw does not occupy the installation space on both sides of the track, thus creating conditions for the installation of the sliding contact line and barcode positioning mechanism.

Detailed Implementation

[0010] The present invention will now be described in detail with reference to the accompanying drawings: A shuttle car track structure with a concealed height adjustment mechanism includes a concrete foundation slab 1 and an I-shaped track 8. Vertical pre-embedded sleeves 2 and anchor bolts 3 are respectively installed on the concrete foundation slab 1. A ground support steel plate 4 is installed at the top end of the vertical pre-embedded sleeve 2, and the ground support steel plate 4 is fixed to the ground at the top end of the vertical pre-embedded sleeve 2 by the anchor bolts 3. The ground support steel plate 4 serves as the supporting foundation for the shuttle car track. A screw head embedding groove 9 is provided on the bottom surface of the I-shaped track 8, with a height adjustment mechanism. The head of the adjusting bolt 6 is movably positioned within the head embedding groove 9. A threaded through hole 5 is provided on the ground support steel plate 4 above the top port of the vertical pre-embedded sleeve 2. An Ω-shaped flange 10 is movably fitted onto the height adjusting bolt 6 below the head. The tail end of the height adjusting bolt 6 is screwed into the threaded through hole 5. A bolt through hole 11 is provided in the middle of the Ω-shaped flange 10. The Ω-shaped flange 10 is movably fitted onto the height adjusting bolt 6 through the bolt through the through hole 11. A wrench-locking hexagonal head 12 is fixedly installed on the height adjusting bolt 6 below hole 11. A locking nut 7 is screwed onto the height adjusting bolt 6 between the wrench-locking hexagonal head 12 and the ground support steel plate 4. The Ω-shaped flange 10 is fixed to the bottom surface of the I-shaped track 8. The top screw head of the height adjusting bolt 6 is movably locked between the Ω-shaped flange 10 and the bottom surface of the I-shaped track 8. By rotating the height adjusting bolt 6 in the forward direction, the lower end of the height adjusting bolt 6 extends into the vertical pre-embedded sleeve 2. During this process, the head of the height adjusting bolt 6 and the fixed wrench engaging the hexagonal head 12 together drive the Ω-shaped flange 10 and the I-shaped track 8 to descend, causing the I-shaped track 8 to lower; conversely, by rotating the height adjusting bolt 6 in the opposite direction, the lower end of the height adjusting bolt 6 is lifted upward from the vertical pre-embedded sleeve 2. During this process, the head of the height adjusting bolt 6 and the fixed wrench engaging the hexagonal head 12 together drive the Ω-shaped flange 10 and the I-shaped track 8 to rise, causing the I-shaped track 8 to rise.

[0011] The Ω-shaped flange 10 is fixed to the bottom surface of the I-shaped track 8 by the flange fixing bolts 13, so that the height adjusting bolt 6 can raise or lower the I-shaped track 8 through the Ω-shaped flange 10.

[0012] A shuttle car 14 is installed on the I-shaped track 8. A sliding contact line power supply mechanism 15 and a positioning code reading mechanism 16 are installed on the shuttle car 14. A sliding contact line 17 is installed on the outer surface of the web of the I-shaped track 8 on one side of the shuttle car 14. The sliding contact line 17 and the sliding contact line power supply mechanism 15 are in movable contact. A positioning barcode 18 is installed on the outer surface of the web of the I-shaped track 8 on the other side of the shuttle car 14. The positioning barcode 18 and the positioning code reading mechanism 16 are correspondingly set. The height adjustment mechanism of the I-shaped track 8 is hidden directly below the I-shaped track 8, which opens up the installation space for other mechanisms on both sides of the I-shaped track 8.

[0013] A method for constructing a shuttle track with a concealed height adjustment mechanism, characterized by the following steps: The first step is to embed the vertical pre-embedded sleeve 2 into the poured concrete when pouring the concrete foundation slab 1 of the shuttle car. The second step is to machine a screw head embedding groove 9 on the bottom surface of the I-shaped track 8, and to movably embed the screw head of the height adjustment bolt 6 into the screw head embedding groove 9, so that the height adjustment bolt 6 is movably suspended on the bottom surface of the I-shaped track 8. The third step is to process a threaded through hole 5 on the ground support steel plate 4, fix the ground support steel plate 4 to the concrete foundation slab 1 with anchor bolts 3, and set the threaded through hole 5 on the top port of the vertical pre-embedded sleeve 2. Step 4: Machining an Ω-shaped flange 10, machining a bolt through hole 11 in the middle of the Ω-shaped flange 10, fitting the Ω-shaped flange 10 onto the height adjusting bolt 6, and fixing it to the bottom surface of the I-shaped track 8 with flange fixing bolts 13; setting a wrench-clamping hexagonal head 12 on the height adjusting bolt 6 below the bolt through hole 11, so that the wrench-clamping hexagonal head 12 is fixedly connected to the height adjusting bolt 6 as one piece, and screwing a lock nut 7 onto the height adjusting bolt 6 below the wrench-clamping hexagonal head 12; Step 5: Place the connected I-shaped track 8, Ω-shaped flange 10 and height adjustment bolt 6 above the ground support steel plate 4. Then, mate the tail end of the height adjustment bolt 6 into the threaded through hole 5, and attach the wrench to the wrench holder hexagon head 12. Rotate the height adjustment bolt 6 with the wrench to adjust the height of the I-shaped track 8. Step 6: After the I-shaped track 8 is adjusted to the designed height, the height adjustment bolt 6 is locked to the ground support steel plate 4 by tightening the locking nut 7.
