Description

Technical Field

[0001] The utility model relates to the field of cranes, in particular to a crane fault detection device. Background Art

[0002] A crane is a mechanical equipment used for lifting and moving heavy objects. It is usually composed of a lifting mechanism, a traveling mechanism, a luffing mechanism and a supporting structure. Cranes are widely used in construction sites, docks, factories and other places where heavy objects need to be moved, and can greatly improve work efficiency and safety.

[0003] When a crane fails, a detection device needs to be used for troubleshooting. It is inconvenient to carry the detection device when climbing to a high place manually. Therefore, a crane fault detection device needs to be used for cooperation. For example, the prior art Chinese patent announcement number "CN208883435U" discloses a crane fault detection device, including a vertical plate, a traction rope and a bearing plate, a bearing platform is arranged on the inner side of the vertical plate, a connecting block is fixedly connected to the outer surface of the door leaf, the traction rope is arranged on the upper surface of the left and right ends of the bearing platform, a first connecting rod is connected to the lower surface of the base, the bearing plate is located below the second connecting rod, a connecting plate is fixedly connected to the middle position of the lower surface of the base, a limiting block is welded to the outer end of the telescopic rod, a fixing plate is fixedly arranged at both ends of the vertical plate, and a side plate is connected to the outer end of the fixing plate, a conveyor belt is installed on the inner side of the side plate, and a convex plate is connected to the outer surface of the conveyor belt. The crane fault detection device can provide anti-fall protection for maintenance personnel when transporting them to a high place, and can transport the tools needed for maintenance to the maintenance personnel, so as to facilitate their maintenance.

[0004] Some crane fault detection devices are driven up by synchronous belts to provide equipment for maintenance workers. In actual operations, it is considered that multiple inspections are usually required when troubleshooting cranes, and similar monitoring devices can only perform vertical lifting operations but not parallel movement. When the inspection position needs to be changed, the entire device needs to be moved, which is not only inconvenient for fault detection but also inconvenient for individual inspection personnel to perform fault troubleshooting, and has low practicality.

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Reference Figure 1-4 A crane fault detection device includes a base 1 and a detection device 2. A support frame 3 is fixedly installed on the top of the base 1. Slide grooves 4 are opened on both sides of the support frame 3, and a support plate 5 is provided on one side. Guide wheels 6 are rotatably connected to both sides of the support plate 5. The guide wheels 6 are rotatably connected in the slide grooves 4. The function of the guide wheels 6 is to fix the support plate 5 to prevent it from swinging when it is driven by the screw rod 71. On the other hand, the friction between the support plate 5 and the support frame 3 is reduced to extend the life of the equipment.

[0022] The top of the support frame 3 is provided with a driving component 7 for driving the support plate 5 to rise and fall, and the top of the support plate 5 is provided with the detection device 2 through a telescopic component 8, and the telescopic component 8 is used to drive the detection device 2 to move.

[0023] Specifically, the driving assembly 7 includes a screw rod 71 rotatably connected between the base 1 and the support frame 3 , a motor 72 is fixedly mounted on the side of the top of the support frame 3 , and a driving pulley 73 is fixedly mounted on the shaft end of the motor 72 .

[0024] Furthermore, one end of the screw rod 71 passes through the support frame 3 and is fixedly mounted with a driven pulley 74, a transmission belt 75 is sleeved between the driving pulley 73 and the driven pulley 74, the support plate 5 is threadedly connected to the screw rod 71, and the screw rod 71 is driven by the motor 72 to drive the support plate 5 to rise and fall to adapt to cranes of different heights.

[0025] It is worth mentioning that the volume of the driving pulley 73 is larger than that of the driven pulley 74. By utilizing the effect that the transmission ratio of the driving pulley 73 is greater than that of the driven pulley 74, the screw rod 71 can be driven to rotate more quickly in cooperation with the transmission belt 75.

[0026] In more detail, the telescopic assembly 8 includes a cylinder 81 fixedly mounted on the top of the support plate 5, the top of the support plate 5 is slidably connected to a U-shaped frame 82, and a fixed frame 83 is fixedly mounted on the top of the U-shaped frame 82, and the axial end of the cylinder 81 is fixedly connected to the side of the U-shaped frame 82.

[0027] In general, the two sides of the fixing frame 83 are rotatably connected with the first connecting rods 84, and the other ends of the first connecting rods 84 are rotatably connected with the second connecting rods 85. The second connecting rods 85 are cross-structured and rotatably connected to the U-shaped frame 82 through round rods 86.

[0028] Finally, a carrier plate 9 is provided on the top of the support plate 5, the detection device 2 is fixedly installed on the top of the carrier plate 9, and a guide groove 87 is opened on its side, and the other ends of a pair of second connecting rods 85 are rotatably connected to the guide groove 87 through guide rods 88, and a pair of guide rods 88 are respectively slidably connected and fixedly connected to the guide groove 87.

[0029] like Figure 4 As shown, when the axis of the cylinder 81 is extended or retracted, it drives the round rod 86 to move. Since one end of a pair of the first connecting rods 84 is fixed by the fixing frame 83, when a pair of the second connecting rods 85 are driven by the round rod 86, they will be further extended or retracted because both ends are constrained by the first connecting rods 84, thereby achieving the effect of driving the detection device 2 to extend or retract.

[0030] Working mode: When working, the motor 72 drives the active pulley 73 to cooperate with the transmission belt 75 to drive the driven pulley 74 to rotate. While rotating, the driven pulley 74 drives the screw rod 71 to rotate and then drives the support plate 5 to rise and fall. When the support plate 5 rises to a suitable position, the axial end of the cylinder 81 extends to drive the round rod 86 to move, and then a pair of first connecting rods 84 and a pair of second connecting rods 85 are extended, driving the detection equipment 2 to move to check the fault point.

[0031] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
