[0026] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0027] As Figures 1 to 6 shown, the present utility model provides a gantry crane for transporting commercial concrete, including a track 1, rollers 2, and a bracket 4. The rollers 2 are movably arranged above the track 1, the bracket 4 is located above the rollers 2, and the bracket 4 is rotatably connected to the rollers 2;

[0028] On one side of the bracket 4, a first connecting plate 5 is fixedly installed. At the bottom of the first connecting plate 5, a housing 13 is fixedly installed. At the top inside the housing 13, a button 18 is fixedly installed. At the top inside the housing 13, a second spring 17 is fixedly installed. At the bottom of the second spring 17, a moving plate 14 is fixedly installed. Above the moving plate 14, a moving rod 15 is fixedly installed. Above the moving rod 15, a pressing plate 16 is fixedly installed. At the bottom of the moving plate 14, a moving frame 19 is fixedly installed. The bottom of the moving frame 19 penetrates through the bottom of the housing 13 and is fixedly installed with a wheel frame 20. On one side of the wheel frame 20, a detection wheel 21 is rotatably installed. The detection wheel 21 is movably connected to the track 1. At the bottom of the first connecting plate 5, a second connecting plate 10 is movably installed. At the bottom of the second connecting plate 10, an inclined frame 11 is fixedly installed. At the bottom of the inclined frame 11, a blower 12 is fixedly installed.

[0029] When the staff uses it, the staff first controls the device to move forward through the controller. As the device moves forward, friction will be generated between the detection wheel 21 and the track 1, so that the detection wheel 21 rolls. When a small stone appears above the track 1, when the detection wheel 21 passes over the small stone, it will move upward. As the detection wheel 21 moves upward, it will drive the wheel frame 20 to move upward. When the wheel frame 20 moves upward, it will drive the moving frame 19 to move upward, causing the moving plate 14 to move upward. As the moving plate 14 moves upward, it will drive the moving rod 15 to move upward. When the moving rod 15 moves upward, it will drive the pressing plate 16 to move upward, and the second spring 17 will be compressed. When the pressing plate 16 presses the button 18, the blower 12 will be started, and the blower 12 will blow strong wind above the track 1.

[0030] By detecting that the detection wheel 21 passes above the gravel, the moving frame 19 is moved upward, thereby driving the moving plate 14 to move upward. The upward movement of the moving plate 14 drives the moving rod 15 to move upward. When the moving rod 15 moves upward, it drives the pressing plate 16 to move upward. When the pressing plate 16 moves upward, it presses the button 18, causing the fan 12 to start. Compared with the traditional device, through the design of the detection wheel 21, when the device moves, it can blow away the gravel above the track 1 in advance, avoiding the gravel from affecting the normal operation of the device, thereby improving the working efficiency of the device.

[0031] Among them, a first spring 6 is fixedly installed above the first connecting plate 5. A pressing frame 7 is fixedly installed above the first spring 6. A telescopic tube 9 is fixedly installed at the bottom of the pressing frame 7. The bottom of the telescopic tube 9 is fixedly connected to the top of the first connecting plate 5. Fixed hooks 8 are fixedly installed at the bottoms on both sides of the pressing frame 7. The fixed hooks 8 penetrate through the upper and lower sides of the first connecting plate 5 and extend into the interior of the second connecting plate 10. The fixed hooks 8 are movably connected to the second connecting plate 10.

[0032] When the staff needs to replace the fan 12, the staff first presses the pressing frame 7 downward. When the pressing frame 7 is pressed, it causes the pressing frame 7 to move downward. When the pressing frame 7 moves downward, it causes the top of the telescopic tube 9 to contract toward the bottom. When the top of the telescopic tube 9 contracts toward the bottom of the telescopic tube 9, it causes the first spring 6 to be compressed, thereby causing the fixed hook 8 to move downward. When the fixed hook 8 moves downward, the bottom end of the fixed hook 8 gradually moves into the interior of the second connecting plate 10. When the bottom end of the fixed hook 8 gradually moves out of the interior of the second connecting plate 10, the second connecting plate 10 connected to the inclined frame 11 and the fan 12 can be removed at this time and replaced and repaired.

[0033] By pressing the pressing frame 7 downward, the first spring 6 is compressed. When the first spring 6 is compressed, at this time the fixed hook 8 will move downward. When the fixed hook 8 moves downward, it drives the bottom end of the fixed hook 8 to gradually move out of the interior of the second connecting plate 10. When the bottom end of the fixed hook 8 completely moves out of the interior of the second connecting plate 10, the fan 12 can be removed at this time. Compared with the traditional device, through the disassembly of the fan 12, it can be avoided that when the fan 12 is damaged, the gravel above the track 1 cannot be blown away, affecting the movement of the device. Through disassembly, the working efficiency of the device is improved.

[0034] Among them, a first bottom plate 33 is fixedly installed above the bracket 4. A protective shell 30 is fixedly installed above the first bottom plate 33.

[0035] The protective shell 30 can provide protection for the rotation of the threaded rod 23, avoiding foreign objects from getting stuck between the threaded rod 23 and the threaded block 24, resulting in abnormal operation.

[0036] Among them, a drive motor 3 is fixedly installed on one side of the support 4, and the transmission shaft of the drive motor 3 penetrates through one side of the support 4 and is fixedly connected to the roller 2.

[0037] Start the drive motor 3 through the controller, and the transmission shaft of the drive motor 3 drives the roller 2 to rotate, thereby driving the device to move forward.

[0038] Among them, a first motor 22 is fixedly installed above the first bottom plate 33, a threaded rod 23 is fixedly installed above the transmission shaft of the first motor 22, the other end of the threaded rod 23 is rotatably connected to the protective shell 30, and a threaded block 24 is threadedly sleeved above the threaded rod 23.

[0039] Start the first motor 22 through the controller to drive the threaded rod 23 to rotate. Since the connection between the threaded block 24 and the threaded rod 23 is provided with the same thread as the threaded rod 23, the threaded block 24 will be driven to move forward as the threaded rod 23 rotates.

[0040] Among them, a connecting frame 25 is fixedly installed at the bottom of the threaded block 24, and the bottom of the connecting frame 25 penetrates through the upper and lower sides of the first bottom plate 33 and is fixedly installed with a second bottom plate 26.

[0041] Drive the movement of the connecting frame 25 through the movement of the threaded block 24. When the connecting frame 25 moves, it will drive the second bottom plate 26 to move.

[0042] Among them, a second motor 27 is fixedly installed at the bottom of the second bottom plate 26, a winding rod 28 is fixedly installed above the transmission shaft of the second motor 27, and a rope 29 is movably sleeved above the winding rod 28.

[0043] Start the second motor 27 through the controller to drive the winding rod 28 to rotate. When the winding rod 28 rotates, it will drive one end of the rope 29 to move downward or upward.

[0044] Among them, a hook 32 is fixedly installed at one end of the rope 29, and the hook 32 is located below the rope 29.

[0045] Hang an object above the hook 32, and drive the hook 32 to move upward or downward through the upward or downward movement of one end of the rope 29.

[0046] Among them, a fixing frame 31 is fixedly installed on one side of the support 4, and one end of the fixing frame 31 is fixedly connected to another support 4.

[0047] Through the design of the fixing frame 31, the connection strength between the supports 4 can be enhanced, and the phenomenon of damage to the supports 4 can be avoided.

[0048] Among them, the number of supports 4 is four and they are evenly distributed below the detection wheel 21, and a first connecting plate 5 is provided on one side of each support 4.

[0049] It can improve the stability of the device during operation, so that the influence of stones can be avoided when the device moves forward and backward.

[0050] The working principle and usage process of the present utility model are as follows:

[0051] When the staff uses it, the staff first controls the device to move forward through the controller. As the device moves forward, friction will be generated between the detection wheel 21 and the track 1, causing the detection wheel 21 to roll. When a small stone appears above the track 1, when the detection wheel 21 passes over the small stone, it will move upward. As the detection wheel 21 moves upward, it will drive the wheel frame 20 upward. When the wheel frame 20 moves upward, it will drive the moving frame 19 upward, causing the moving plate 14 to move upward. As the moving plate 14 moves upward, it will drive the moving rod 15 upward. When the moving rod 15 moves upward, it will drive the pressing plate 16 upward, and the second spring 17 will be compressed. When the pressing plate 16 presses the button 18, the blower 12 will be started, and the blower 12 will blow strong wind above the track 1.

[0052] When the staff needs to replace the blower 12, the staff first presses the pressing frame 7 downward. When the pressing frame 7 is pressed, it will cause the pressing frame 7 to move downward. When the pressing frame 7 moves downward, it will cause the top of the telescopic tube 9 to contract toward the bottom. When the top of the telescopic tube 9 contracts toward the bottom of the telescopic tube 9, it will cause the first spring 6 to be compressed, causing the fixed hook 8 to move downward. When the fixed hook 8 moves downward, the bottom end of the fixed hook 8 will gradually move into the inside of the connecting plate two 10. When the bottom end of the fixed hook 8 gradually moves out of the inside of the connecting plate two 10, at this time, the connecting plate two 10 connected to the inclined frame 11 and the blower 12 can be removed and replaced and repaired.
