[0002] Crane basket, also known as crane hanging basket, refers to a multi-action crane hanging basket machine that can vertically lift and horizontally carry heavy objects within a certain range. The hanging basket is very popular among workers because it can hold many items and has low production cost. Therefore, a crane safety operation basket is needed. However, the existing device still has certain defects when in use, such as:

[0003] When the device is in use and the basket is lifted up, since the rods between the basket and the crane are rotatably connected, the basket is easily affected by wind speed and moving speed in the air, causing the basket to shake and tilt, which may cause the workers to fall from the basket and cause serious personal safety hazards. Utility Model Content

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] When implementing: Figure 1-4 As shown, a crane safety operation basket, 1. A crane safety operation basket, characterized in that it includes a support base 1, a connecting block 2 and a hanging basket frame 3: the side of the support base 1 is provided with a connecting block 2, the upper end of the support base 1 is provided with a hanging basket frame 3, and the upper end of the connecting block 2 is provided with a balancing structure 19;

[0022] The balancing structure 19 includes a hydraulic rod 8, a movable block 9 and a connecting head 10. The upper end of the connecting block 2 is provided with the hydraulic rod 8, the upper end of the hydraulic rod 8 is provided with the connecting head 10, and the upper end of the connecting head 10 is provided with the movable block 9;

[0023] When the device is in use, first fix the hoisting rod 5 to the top of the crane's boom through the splicing block 6 and the connecting bolts 7, and then the staff enters the inside of the device, and then lifts the hanging basket through the crane. At this time, when the hanging basket is affected by the wind speed and the moving speed during the process, the hanging basket shakes and tilts. At this time, when the hanging basket tilts to the left, the hydraulic rod 8 is opened and the hydraulic rod 8 is extended, so that the connecting head 10 pushes the movable block 9 to make the lower part of the hanging basket deviate to the left, so as to move the upper part of the hanging basket to the right and keep the hanging basket in a balanced state. At this time, when the hanging basket tilts to the right, the hydraulic rod 8 contracts and pulls the movable block 9 through the connecting head 10 to deviate the lower part of the hanging basket in the direction of the hoisting rod 5, and the upper part of the hanging basket deviates to the left, so as to keep the hanging basket balanced, to prevent the hanging basket from shaking and tilting due to the wind speed and the moving speed during the lifting process, causing the staff to fall from the hanging basket and cause serious injuries.

[0024] The movable block 9 is rotatably connected to the connecting head 10, a rotating disk 4 is arranged on the side of the hanging basket frame 3, a hoisting rod 5 is arranged on the side of the rotating disk 4, and the hoisting rod 5 is rotatably connected to the rotating disk 4;

[0025] The movable block 9 is slidably connected to the hoisting rod 5, a splicing block 6 is arranged on the side of the hoisting rod 5, and a connecting bolt 7 is arranged on the side of the splicing block 6;

[0026] When the device is in use, the splicing block 6 is first fitted to the top of the crane, and then the connecting bolt 7 is screwed into the inside of the splicing block 6 to fix the splicing block 6 to the top of the crane, thereby fixing the lifting rod 5, and then the crane lifts the hanging basket through the lifting rod 5.

[0027] A support column 11 is provided on the side of the hanging basket frame 3, and a fixing column 12 is provided on the side of the hanging basket frame 3;

[0028] A hanging basket door 13 is provided on the side of the support column 11, the support column 11 is rotatably connected to the hanging basket door 13, and a limiting block 14 is provided on the side of the hanging basket door 13;

[0029] When the device is in use, the hanging basket is first fixed to the top of the crane through the lifting rod 5, and then the hanging basket door 13 is opened to enable the staff to move the tools to the upper end of the supporting base 1, and then the hanging basket door 13 is closed to allow the crane to lift the hanging basket.

[0030] A support spring 15 is disposed inside the limit block 14, and a clamping block 16 is disposed on the side of the support spring 15, and the clamping block 16 is slidably connected to the limit block 14;

[0031] A pressing plate 17 is provided on the side of the clamping block 16, and the pressing plate 17 is slidably connected with the limit block 14. A clamping slot 18 is provided inside the fixing column 12. The clamping block 16 is arranged in a trapezoidal shape, and the clamping block 16 is installed inside the clamping slot 18 when embedded.

[0032] When the device is in use and the hanging basket door 13 needs to be opened, the upper and lower pressing plates 17 are pressed toward the middle at the same time, so that the pressing plate 17 drives the card block 16 to move toward the middle, so that the card block 16 is pulled out from the inside of the card slot 18, and then the hanging basket door 13 is opened to allow the staff to enter the inside of the device, and then the hanging basket door 13 is closed again to allow the limit block 14 to enter the inside of the fixed column 12. First, because the surface of the card block 16 facing the fixed column 12 is inclined, the fixed column 12 pushes the card block 16 to the inside of the limit block 14. When the limit block 14 is completely aligned with the fixed column 12, the fixed column 12 pushes the card block 16 to the inside of the limit block 14. When fitting, the rebound force of the support spring 15 is used to push the card block 16 to the inside of the card slot 18 to engage and fix the limit block 14 and fix the hanging basket door 13. In order to prevent the workers from accidentally touching the switch of the hanging basket door 13 and causing the hanging basket door 13 to open, the upper and lower pressing plates 17 need to be pressed at the same time to open the hanging basket door 13, and the pressing plates 17 are set on the side, so as to effectively prevent the workers from accidentally touching the switch of the hanging basket door 13 during work, causing the hanging basket door 13 to open, and causing the workers to fall from the inside of the hanging basket.

[0033] When the utility model is in use, the hoisting rod 5 is first fixed to the top of the crane by the splicing block 6 and the connecting bolt 7, and then the pressing plate 17 is pressed toward the middle at the same time to drive the block 16 to disengage from the slot 18 to open the hanging basket door 13. Then the staff carries the tool into the device and then closes the hanging basket door 13. First, the fixing column 12 pushes the block 16 back to the inside of the limit block 14. Then, when the limit block 14 is completely fitted with the fixing column 12, the block 16 is pushed out by the rebound force of the supporting spring 15, so that the block 16 enters the inside of the slot 18, so as to fix the limit block 14 and the hanging basket door 13, and the pressing plate 17 is arranged on the side to prevent the staff from accidentally touching it. At this time, the crane lifts the hanging basket. When the hanging basket shakes due to the wind speed and the moving speed, the hydraulic rod 8 is extended and retracted to keep the hanging basket balanced at all times, so as to prevent the staff from falling due to the shaking and tilting of the hanging basket.

[0034] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
