Description

Technical Field

[0001] This utility model relates to the field of brick processing technology, and in particular to a lifting overhead crane device for packaging bricks. Background Technology

[0002] Bricks are a common building material, usually made from raw materials such as clay, sand and lime through high-temperature firing. Bricks have good strength and durability and are widely used in building structures such as walls, floors and chimneys.

[0003] When the prepared bricks are sold, they need to be packaged in batches. The packaged bricks are heavy and need to be transferred using a crane. For example, an energy-saving building lifting crane disclosed in Chinese patent CN214692932U is used to lift and lower the top column by rotating the winding device driven by the lifting motor, changing the length of the fire rope outside the winding device. When the top column is lifted and lowered between the two side columns, it only moves within the slide groove. When the lifting hook on the top column is used to transport heavy objects, the side columns may sway up and down or back and forth, which poses a certain safety hazard. Therefore, we propose a lifting crane device for packaging bricks. Utility Model Content

[0004] The purpose of this invention is to provide a lifting overhead crane device for packaging bricks, which has the effect of high safety due to the stability of the overhead crane.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a lifting overhead crane device for packaging bricks, comprising two bases, side columns mounted on the bases, a bracket connecting the two side columns, a top column slidably mounted between the two side columns, a moving device slidably connected to the top column, a hook mounted on the moving device, a side plate mounted on one side of the side column, a guide wheel mounted on the other side of the side column, a lifting wheel mounted on the top column, and a lifting assembly mounted on one side of the base, bypassing the guide wheel and the lifting wheel and connected to the side plate. Limiting grooves are provided on both the left and right sides of the top column. A stabilizing component with one end locked in the limiting groove is movably installed in the side column. A driving component for driving the stabilizing component to move is mounted on the bracket.

[0006] By adopting the above technical solution, the lifting component starts and drives the top column to slide up and down between the two side columns. After the top column moves down to a lower position, the hook can lift the packaged bricks. Then the top column drives the bricks to move up to a certain height. The moving device drives the hook to move laterally, completing the overhead crane operation for the bricks. During the up and down movement of the top column, the drive component starts and causes the stabilizing component to connect or separate from the limiting groove. When the top column moves, the stabilizing component separates from the limiting groove without affecting the movement of the top column. When the top column moves to the corresponding overhead crane height, the stabilizing component connects with the limiting groove, locking the top column from both sides to prevent it from swaying after being lifted with heavy bricks, thus improving the stability and safety of the overhead crane.

[0007] A further feature of this invention is that the base is a trapezoidal base that is narrower at the top and wider at the bottom.

[0008] By adopting the above technical solutions, the stability of the base support is improved, thereby improving the stability of the overhead crane.

[0009] A further feature of this invention is that the lifting assembly includes a connecting seat mounted on one side of the base, a winding motor mounted on the connecting seat, a winding reel connected to the output shaft of the winding motor, and a fire rope wound around the outside of the winding reel.

[0010] A further feature of this invention is that two guide wheels are provided on the top column, and the fire rope, on the side away from the winding reel, passes around the top of the guide wheel and through the bottom of the lifting wheel to connect with the side plate.

[0011] By adopting the above technical solution, the winding motor starts and drives the winding reel to rotate, changing the length of the fire rope exposed on the outside of the winding reel. When the length of the fire rope exposed on the outside of the winding reel becomes shorter, the top column moves upward between the two side columns, and vice versa, thus completing the overhead crane operation on the bricks.

[0012] A further feature of this invention is that the stabilizing component includes a column slidably installed inside the side column, a plurality of stabilizing blocks installed on the column, a connecting spring connecting the column and the side column, and a push rod installed on the column and passing through the bracket.

[0013] By adopting the above technical solution, the drive component starts to push the two push rods closer to each other or further apart. When the two push rods move away from each other, the stabilizing block separates from the limiting groove, and the top column can move on the side column. When the two push rods move closer to each other, the stabilizing block connects with the limiting groove, locking the top column from both sides to prevent it from swaying after hoisting heavy bricks on the top column, thus improving the stability of the top column overhead crane and making it safer. The setting of multiple stabilizing blocks can stabilize the top column at different heights, making it safer and more stable when hoisting bricks at multiple different heights.

[0014] A further feature of this invention is that the interior of the side column is hollow and a strip-shaped hole is provided on the inner wall of the side near the top column for the stabilizing block to pass through.

[0015] A further feature of this invention is that the stabilizing blocks are distributed at equal intervals and the dimensions of the stabilizing blocks are adapted to the dimensions of the limiting grooves.

[0016] By adopting the above technical solution, the stabilizing block can be extended into the limiting groove to support the top column, thereby improving the stability of the overhead crane.

[0017] A further feature of this invention is that a rubber pad is also installed on the stabilizing block.

[0018] By adopting the above technical solution, the rubber pad can make the connection between the stabilizing block and the limiting groove tighter.

[0019] A further feature of this invention is that the drive assembly includes a drive motor mounted on the bracket, a rotating wheel connected to the output shaft of the drive motor, and a push rod hinged to the rotating wheel.

[0020] A further feature of this invention is that two push rods are provided, and the other side of the push rod is hinged to the push rod.

[0021] By adopting the above technical solution, the drive motor starts and drives the drive wheel to rotate, which in turn drives the two push rods to rotate. The push rods are hinged to the push rods, which pushes the two push rods closer to each other or further away. When the two push rods move away from each other, the stabilizing block separates from the limiting groove, and the top column can move on the side column. When the two push rods move closer to each other, the stabilizing block connects with the limiting groove, locking the top column from both sides to prevent it from swaying after lifting heavy bricks, thus improving the stability and safety of the top column overhead crane.

[0022] The beneficial effects of this utility model are:

[0023] 1. The drive motor starts and drives the drive wheel to rotate, which in turn drives the two push rods to rotate. The push rods are hinged to the push rods, which pushes the two push rods closer to each other or further apart. When the two push rods move away from each other, the stabilizing block separates from the limiting groove, and the top column can move on the side column. When the two push rods move closer to each other, the stabilizing block connects with the limiting groove, locking the top column from both sides to prevent it from swaying after lifting heavy bricks, thus improving the stability and safety of the top column overhead crane.

[0024] 2. The installation of multiple stabilizing blocks can stabilize the top column at different heights, making it safer and more stable when gantry cranes are used to lift bricks at multiple different heights. Attached Figure Description

[0031] The technical solution of this utility model will now be clearly and completely described with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0032] Please see Figure 1-4This utility model provides a lifting overhead crane device for packaging bricks, including two bases 1, side columns 2 mounted on the bases 1, a bracket 11 connecting the two side columns 2, a top column 3 slidably mounted between the two side columns 2, a moving device 4 slidably connected to the top column 3, a hook 5 mounted on the moving device 4, a side plate 6 mounted on one side of the side column 2, a guide wheel 7 mounted on the other side of the side column 2, a lifting wheel 8 mounted on the top column 3, and a lifting assembly 9 mounted on one side of the base 1, bypassing the guide wheel 7 and the lifting wheel 8 and connected to the side plate 6. Limiting grooves 10 are provided on both the left and right sides of the top column 3. A stabilizing assembly 12 with one end locked in the limiting groove 10 is movably installed in the side column 2. A driving assembly 13 for driving the stabilizing assembly 12 to move is mounted on the bracket 11.

[0033] The lifting assembly 9 starts, causing the top column 3 to slide up and down between the two side columns 2. After the top column 3 moves down to a lower position, the hook 5 can lift the packaged bricks. Then, the top column 3 moves the bricks up to a certain height. The moving device 4 drives the hook 5 to move laterally, completing the overhead crane operation for the bricks. During the up and down movement of the top column 3, the drive assembly 13 starts, causing the stabilizing assembly 12 to connect or separate from the limiting groove 10. When the top column 3 moves, the stabilizing assembly 12 separates from the limiting groove 10, without affecting the movement of the top column 3. When the top column 3 moves to the corresponding overhead crane height, the stabilizing assembly 12 connects with the limiting groove 10, locking the top column 3 from both sides to prevent it from swaying after being lifted with heavy bricks, thus improving the stability and safety of the overhead crane operation.

[0034] The specific structural design of the mobile device 4 is based on Chinese patent CN214692932U, which is prior art.

[0035] The base 1 is a trapezoidal base that is narrower at the top and wider at the bottom, which improves the stability of the support provided by the base 1 and thus improves the stability of the overhead crane.

[0036] The lifting assembly 9 includes a connecting seat 91 mounted on one side of the base 1, a winding motor 92 mounted on the connecting seat 91, a winding reel 93 connected to the output shaft of the winding motor 92, and a fire rope 94 wound around the outside of the winding reel 93. Two guide wheels 7 are provided on the top column 3. The side of the fire rope 94 away from the winding reel 93 passes around the top of the guide wheel 7 and through the bottom of the lifting wheel 8 to connect with the side plate 6. The winding motor 92 starts and drives the winding reel 93 to rotate, changing the length of the fire rope 94 exposed outside the winding reel 93. When the length of the fire rope 94 exposed outside the winding reel 93 becomes shorter, the top column 3 moves upward between the two side columns 2, and vice versa, thus completing the overhead crane operation on the bricks.

[0037] The stabilizing component 12 includes a column 121 slidably installed inside the side column 2, multiple stabilizing blocks 122 installed on the column 121, a connecting spring 123 connecting the column 121 and the side column 2, and a push rod 124 installed on the column 121 and passing through the bracket 11. The driving component 13 is activated to push the two push rods 124 closer to each other or further apart. When the two push rods 124 move away from each other, the stabilizing block 122 separates from the limiting groove 10, and the top column 3 can move on the side column 2. When the two push rods 124 move closer to each other, the stabilizing block 122 connects with the limiting groove 10, and locks the top column 3 from the left and right sides to prevent it from swaying after a heavy brick is hoisted on the top column 3, thereby improving the stability of the top column 3 and increasing safety. The multiple stabilizing blocks 122 can stabilize the top column 3 at different heights, making it safer and more stable when hoisting bricks at multiple different heights.

[0038] The interior of the side column 2 is hollow, and the inner wall of the side column 3 near the top column 3 has a strip-shaped hole for the stabilizing block 122 to pass through. The stabilizing blocks 122 are evenly distributed and the size of the stabilizing blocks 122 is adapted to the limiting groove 10, so that the stabilizing blocks 122 can extend into the limiting groove 10 to support the top column 3 and improve the stability of the overhead crane.

[0039] A rubber pad is also installed on the stabilizing block 122, which can make the connection between the stabilizing block 122 and the limiting groove 10 more tight.

[0040] The drive assembly 13 includes a drive motor 131 mounted on the bracket 11, a rotating wheel 132 connected to the output shaft of the drive motor 131, and a push rod 133 hinged to the rotating wheel 132. Two push rods 133 are provided, and the other side of each push rod 133 is hinged to a push rod 124. When the drive motor 131 starts, it drives the drive wheel 132 to rotate, thereby driving the two push rods 133 to rotate. The push rods 133 are hinged to the push rods 124, thus pushing the two push rods 124 closer together or further apart. When the two push rods 124 move further apart, the stabilizing block 122 separates from the limiting groove 10, allowing the top column 3 to move on the side column 2. When the two push rods 124 move closer together, the stabilizing block 122 connects to the limiting groove 10, locking the top column 3 from both sides to prevent it from swaying after being loaded with heavy bricks, thus improving the stability and safety of the overhead crane.
