Description

Technical Field

[0001] This utility model relates to the technical field of track-type trolleys, and more specifically, to a track-type trolley balance wheel set. Background Technology

[0002] Traditional trolley transmission mechanisms typically employ a single-wheel assembly and multi-wheel drive system, with wheels installed in multiple rows at the bottom of the trolley. This structure is susceptible to factors such as frame deformation and track settlement, leading to uneven wheel pressure and easy wheel damage, which in turn affects the trolley's load-bearing capacity.

[0003] The old-style trolley transmission mechanism uses a high-strength balance frame and drive shaft to ensure synchronous power transmission and stable weight bearing, preventing operational failures caused by structural deformation. However, the rigid connection makes it inconvenient to install and dismantle the balance frame, which in turn causes damage to the balance wheel, making it difficult to replace.

[0004] Therefore, a track-type trolley balancing wheel assembly is proposed to address the above problems. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a track-type trolley balance wheel set to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A track-type trolley balance wheel assembly includes two load-bearing beams, multiple crossbeams installed between the two load-bearing beams, and side beams provided in opposite directions on both load-bearing beams. The load-bearing beams, crossbeams, and side beams are fixedly connected by connecting beams, and the load-bearing beams, crossbeams, and side beams are enclosed by steel plates. The load-bearing beams, crossbeams, side beams, and connecting beams are all fixed by welding. A frame mechanism is provided above the two load-bearing beams, and two balance wheel mechanisms are installed below the two load-bearing beams. Two first connecting rings are installed on one side of the two side beams in opposite directions, and a receiving block is installed between the two first connecting rings. A transition block is installed on one side of the receiving block.

[0007] Preferably, the frame structure includes connecting plates, frame columns, first horizontal bars, connecting rods, second horizontal bars, and diagonal braces. Connecting plates are installed at both ends of the frame columns. One end of the connecting plate of the frame column is connected to the connecting beam with anchor bolts. The end of the connecting plate of the frame column away from the connecting beam is bolted to the first horizontal bar. The first horizontal bars are fixed to each other and to each other with the second horizontal bar by welding connecting rods. A diagonal brace is installed below the connecting rod between the endpoints of the first and second horizontal bars. The end of the diagonal brace away from the connecting rod is installed on one side of the frame column body.

[0008] Preferably, the balance wheel mechanism includes a mounting plate, screws, clamps, triangular plates, a balance wheel frame, a rotating shaft, balance wheels, and studs. Mounting plates are installed below each load-bearing beam, and the mounting plates are fixedly connected to the load-bearing beam by multiple screws. Two sets of clamping structures are installed below each mounting plate, and each set contains two clamps. Two triangular plates are installed between each mounting plate and clamp. A balance wheel frame is installed between each pair of clamps, and the clamps and balance wheel frames are fixed by a rotating shaft. Two balance wheels are installed inside each balance wheel frame, and the two balance wheels are connected to the balance wheel frame by studs.

[0009] Preferably, a second connecting ring is provided on the outer side of the connecting rods on both sides of the frame mechanism.

[0010] Preferably, two pads are installed above the side beam, and clamping blocks are installed on each pad. The clamping blocks and pads are fixed to the side beam by bolts. A stop block is installed on the opposite side of the two clamping blocks. A buffer plate is installed above the side beam away from the clamping blocks, and the side beam and the buffer plate are connected by hinge blocks.

[0011] Preferably, the clamping blocks and the buffer plate are on the same plane, and the width of the buffer plate is less than the width between the two clamping blocks.

[0012] The technical effects and advantages of this utility model are as follows: Compared with existing technologies, this track-type trolley balance wheel assembly uses welding to fix the load-bearing beams, crossbeams, side beams and connecting beams. The rigid connection ensures synchronous power transmission and stable weight bearing, preventing operational failures caused by structural deformation. The frame mechanism is fixed with anchor bolts, making it easy to install, disassemble and maintain. The bolt connection and the use of diagonal bracing make the frame mechanism easy to install and disassemble while increasing structural rigidity.

[0013] Compared with existing technologies, this rail-type trolley balance wheel assembly has two balance wheel mechanisms installed under each load-bearing beam. The two balance wheel mechanisms contain four sets of balance wheels. When the rail-type trolley passes through track joints or uneven areas, the balance wheels will adapt to the height changes by swinging or rolling, keeping the trolley's center of gravity stable and avoiding tilting or swaying. This ensures that the balance wheels are evenly stressed, thereby improving the load-bearing capacity. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example As attached Figures 1 to 4 The illustrated track-type trolley balance wheel assembly includes two load-bearing beams 1, with multiple crossbeams 2 installed between the two load-bearing beams 1. Side beams 3 are provided in opposite directions on both load-bearing beams 1. The load-bearing beams 1, crossbeams 2, and side beams 3 are fixedly connected by connecting beams 4. The load-bearing beams 1, crossbeams 2, and side beams 3 are enclosed by steel plates 5. The load-bearing beams 1, crossbeams 2, side beams 3, and connecting beams 4 are all fixed by welding, ensuring that a frame mechanism 6 is provided above the two load-bearing beams 1. Two balance wheel mechanisms 7 are installed below each of the two load-bearing beams 1. Two first connecting rings 8 are installed on one side of each of the two side beams 3 in opposite directions, and a receiving block 9 is installed between each of the two first connecting rings 8. A transition block 10 is installed on one side of the receiving block 9. The load-bearing beam 1, crossbeam 2, side beam 3 and connecting beam 4 are all fixed by welding. The rigid connection ensures synchronous power transmission and stable weight bearing, and prevents operation failures caused by structural deformation. The frame mechanism 6 is fixed with anchor bolts, making it easy to install, disassemble and maintain. Two balance wheel mechanisms 7 are installed under the load-bearing beam 1. The two balance wheel mechanisms 7 contain four sets of balance wheels. When the rail-type trolley passes through the rail joint or uneven area, the balance wheel will adapt to the height change by its own swing or rolling, so that the center of gravity of the trolley remains stable and avoids tilting or shaking. This makes the balance wheel bear force evenly, thereby improving the load-bearing capacity.

[0021] The frame structure 6 includes a connecting plate 601, a frame column 602, a first horizontal bar 603, a connecting rod 604, a second horizontal bar 605, and a diagonal brace 606. Connecting plates 601 are installed at both ends of the frame column 602. One end of the connecting plate 601 of the frame column 602 is anchored to the connecting beam 4. The end of the connecting plate 601 of the frame column 602 away from the connecting beam 4 is bolted to the first horizontal bar 603. The first horizontal bars 603 are welded together and to the second horizontal bar 605 via connecting rods 604. A diagonal brace 606 is installed below the connecting rod 604 between the endpoints of the first horizontal bar 603 and the second horizontal bar 605. The end of the diagonal brace 606 away from the connecting rod 604 is installed on one side of the frame column 602. The bolted connections and the use of diagonal braces 606 for support facilitate the installation and disassembly of the frame structure 6 while increasing structural rigidity.

[0022] The balance wheel mechanism 7 includes a mounting plate 701, screws 702, clamping plates 703, triangular plates 704, a balance wheel frame 705, a rotating shaft 706, a balance wheel 707, and studs 708. Mounting plates 701 are installed below each load-bearing beam 1, and the mounting plates 701 are fixedly connected to the load-bearing beam 1 by multiple screws 702. Two sets of clamping structures are installed below each mounting plate 701, and each set contains two clamping plates 703. Two triangular plates 704 are installed between each mounting plate 701 and clamping plate 703, and a balance wheel is installed between each clamping plate 703. The wheel frame 705 and the clamping plate 703 are both fixed by the rotating shaft 706. The balance wheel frame 705 has two balance wheels 707 installed inside, and the two balance wheels 707 are connected to the balance wheel frame 705 by the studs 708. The two balance wheel mechanisms 7 contain four sets of balance wheels, so that when the rail-type trolley passes through the rail joint or uneven area, the balance wheels will adapt to the height change by swinging or rolling, so that the center of gravity of the trolley remains stable and avoids tilting or shaking, so that the balance wheels are evenly stressed, thereby improving the load-bearing capacity.

[0023] Among them, the outer sides of the connecting rods 604 on both sides of the frame mechanism 6 are provided with second connecting rings 16. The frame mechanism 6 is connected through the second connecting rings 16, which increases the overall stress points of the equipment and increases the structural stability.

[0024] Two pads 11 are installed above the side beam 3, and clamping blocks 12 are installed on each pad 11. The clamping blocks 12 and pads 11 are fixed to the side beam 3 by bolts. A stop block 13 is installed on the opposite side of the two clamping blocks 12. A buffer plate 14 is installed above the side beam 3 on the side away from the clamping blocks 12. The side beam 3 and the buffer plate 14 are connected by a hinge block 15. The combination of clamping blocks 12 and buffer plate 14 provides buffering for the equipment before and after operation changes, thus preventing structural damage.

[0025] The clamping block 12 and the buffer plate 14 are on the same plane, and the width of the buffer plate 14 is less than the width between the two clamping blocks 12, so that the buffer plate 14 can easily enter and exit the clamping block 12, and is buffered by the stop block 13 inside the clamping block 12.

[0026] The working process of this utility model is as follows: First, the load-bearing beam 1, the crossbeam 2, the side beam 3 and the connecting beam 4 are all fixed by welding. The rigid connection ensures synchronous power transmission and stable weight bearing, and prevents operational failures caused by structural deformation. The frame mechanism 6 is fixed by anchor bolts to make it easy to install, disassemble and maintain. The frame mechanism 6 is easy to install and disassemble while increasing the structural rigidity through bolt connection and support by diagonal brace 606.

[0027] Then, two balance wheel mechanisms 7 are installed under each load-bearing beam 1. The two balance wheel mechanisms 7 contain four sets of balance wheels. When the rail-type trolley passes through the rail joints or uneven areas, the balance wheels will adapt to the height changes by swinging or rolling, so that the center of gravity of the trolley remains stable and avoids tilting or swaying. This makes the balance wheels bear the force evenly and thus improves the load-bearing capacity.

[0028] Finally, when the speed changes, the buffer plate 14 enters the inside of the clamping block 12 and is buffered by the stop block 13 inside the clamping block 12 to prevent the structure from being damaged.
