[0001] The utility model relates to the technical field of hoisting equipment, in particular to a hoisting equipment with a protection structure. Background Technique

[0002] The cantilever crane for aluminum block production plays an important role in industrial production, mainly reflected in improving work efficiency, saving space, enhancing safety, wide applicability and reducing costs. The cantilever crane can quickly and accurately move goods from one place to another, greatly reducing the time and labor intensity of manual handling, thus significantly improving work efficiency.

[0003] When using the cantilever crane, it is necessary to hang the fixed aluminum block on the hook, then start the winding equipment to make it rise, and then rotate it to the appropriate position and lower it. However, during the rising or rotating process, there may be shaking, which may cause the hook to come off, resulting in the aluminum block falling off and causing injury to the operator. Content of the Utility Model

[0004] The purpose of the utility model is to provide a hoisting equipment with a protection structure to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A hoisting equipment with a protection structure, including a support column, a rotating plate is rotatably installed on the outer wall of the support column, a boom is rotatably installed at the top of the support column, a reinforcing plate is fixedly installed on the top of the rotating plate, the top of the reinforcing plate is fixedly installed at the bottom of the boom, a winding mechanism is arranged inside the boom, a steel wire rope is wound inside the winding mechanism, an installation plate is fixedly installed at the bottom of the steel wire rope, a fixed column is fixedly installed inside the installation plate, a hook is slidably installed at the through hole of the fixed column, an anti - detachment mechanism is arranged on the outer wall of the hook, and a clamping mechanism is arranged on the outer wall of the hook. The anti - detachment mechanism includes:

[0006] A return spring, the top of the return spring is fixedly installed at the bottom of the convex block on the top of the hook, which can reset the hook when the hook does not lift the heavy object and open the shielding plate, facilitating the taking of the rope in the hook. The end of the return spring far from the hook is fixedly installed on the outer wall of the fixed column, and a rotating rod penetrates through the side of the hook and is rotatably connected at the penetration point;

[0007] A shielding plate, the through hole of the shielding plate is fixedly installed on the outer wall of the rotating rod, an eccentric column is fixedly installed at the eccentric position on the front of the rotating rod, and a hollow rod is attached to the outer wall of the eccentric column, which can drive the eccentric column to rotate, thereby driving the rotating rod to rotate.

[0008] Preferably, a movable telescopic rod is fixedly installed at the top of the hollow rod, and a movable spring is fixedly installed inside the movable telescopic rod, which can reset the movable telescopic rod after being stretched.

[0009] Preferably, a fixing block is fixedly installed at one end of the movable telescopic rod away from the hollow rod for fixing the position of the movable telescopic rod, and the back surface of the fixing block is fixedly installed on the front surface of the mounting plate.

[0010] Preferably, the clamping mechanism includes: an extrusion telescopic rod, and the top of the extrusion telescopic rod is fixedly installed at the bottom of the shielding plate.

[0011] Preferably, an extrusion spring is fixedly installed inside the extrusion telescopic rod.

[0012] Preferably, there are two groups of the shielding plate, the hollow rod and the movable spring, and they are symmetric about the central axis on the front surface of the mounting plate, and are symmetrically distributed on the front and back sides of the mounting plate, which can shield both sides of the hook to prevent the hook from disengaging.

[0013] Compared with the prior art, the present invention provides a hoisting device with a protection structure, which has the following beneficial effects:

[0014] 1. For the hoisting device with a protection structure, after hanging the fixed aluminum block rope into the hook and starting the winding mechanism, the steel wire rope can be wound, and at the same time, the mounting plate drives the hook to move upward. When the hook moves upward, because there is a heavy object hanging, the hook will slide downward in the fixed column, and the return spring is compressed. At this time, the rotating rod will move downward, and at the same time, the eccentric column will be reset by the force of the movable spring, so that the hollow rod drives the eccentric column to rotate, and when the rotating rod rotates, it will drive the shielding plate to block the notch of the hook, which can prevent the rope from disengaging and thus injuring the operator.

[0015] 2. For the hoisting device with a protection structure, through the rotation of the shielding plate mentioned above, the extrusion telescopic rod can be driven to rotate, and at the same time, the arc-shaped clamping plate will also rotate, so that the arc-shaped clamping plate pushes the rope in the hook until it is clamped. If the rope is relatively thick, then the extrusion telescopic rod will be compressed during rotation, which can clamp the hook and prevent it from shaking during movement, resulting in the aluminum block falling off and injuring people.

Specific implementation manner

[0021] As Figures 1 - 4 shown, the present utility model provides a technical solution: a hoisting device with a protection structure, including a support column 1, a rotating plate 2 is rotatably installed on the outer wall of the support column 1, a lifting arm 3 is rotatably installed at the top of the support column 1, a reinforcing plate 4 is fixedly installed on the top of the rotating plate 2, the top of the reinforcing plate 4 is fixedly installed at the bottom of the lifting arm 3, a winding mechanism 5 is arranged inside the lifting arm 3, a steel wire rope 6 is wound inside the winding mechanism 5, a mounting plate 7 is fixedly installed at the bottom of the steel wire rope 6, a fixed column 8 is fixedly installed inside the mounting plate 7, a hook 9 is slidably installed at the through - hole of the fixed column 8. Then, the rope of the fixed aluminum block is hung into the hook 9. Starting the winding mechanism 5 can wind the steel wire rope 6, and at the same time drive the mounting plate 7 to drive the hook 9 to move upward. By pulling the mounting plate 7 to make it rotate, the lifting arm 3 can drive the reinforcing plate 4 and the rotating plate 2 to rotate, so as to move the object to a suitable position. An anti - detachment mechanism 10 is arranged on the outer wall of the hook 9, which can prevent the rope fixing the aluminum block from detaching from the hook 9. A clamping mechanism 11 is arranged on the outer wall of the hook 9 to prevent the rope from shaking in the hook 9.

[0022] Specifically, the anti-disengagement mechanism 10 includes a return spring 101, a rotating rod 102, a shielding plate 103, an eccentric column 104, a hollow rod 105, a movable telescopic rod 106, a movable spring 107, and a fixed block 108. The top of the return spring 101 is fixedly installed at the bottom of the convex block on the top of the hook 9, and the end of the return spring 101 away from the hook 9 is fixedly installed on the outer wall of the fixed column 8. The rotating rod 102 penetrates through the side of the hook 9 and is rotatably connected at the penetration point. The shielding plate 103 is fixedly installed on the outer wall of the rotating rod 102 at the through hole of the shielding plate 103. An eccentric column 104 is fixedly installed at the eccentric position on the front of the rotating rod 102. When the hook 9 moves upward, because there is a heavy object hanging, the hook 9 will slide downward in the fixed column 8, and the return spring 101 is compressed. At this time, the rotating rod 102 will move downward, and at the same time, the eccentric column 104 will also move downward. The outer wall of the eccentric column 104 is attached to the hollow rod 105. The top of the hollow rod 105 is fixedly installed with a movable telescopic rod 106. A movable spring 107 is fixedly installed inside the movable telescopic rod 106. At this time, the force of the movable spring 107 resetting will cause the movable telescopic rod 106 to pull the hollow rod 105 to rotate upward, so that the eccentric column 104 can drive the rotating rod 102 to rotate. The shielding plate 103, the hollow rod 105, and the movable spring 107 are provided in two groups and are symmetrically distributed on the front and back sides of the mounting plate 7 with the central symmetry axis of the front of the mounting plate 7 as the axis of symmetry, which can shield both the left and right sides of the hook 9 to prevent the hook from disengaging. The end of the movable telescopic rod 106 away from the hollow rod 105 is fixedly installed with a fixed block 108. The back of the fixed block 108 is fixedly installed on the front of the mounting plate 7. When the rotating rod 102 rotates, the shielding plate 103 will block the notch of the hook 9, which can prevent the rope from disengaging the hook and thus injuring the operator.

[0023] Specifically, the clamping mechanism 11 includes an extrusion telescopic rod 111, an extrusion spring 112, and an arc-shaped clamping plate 113. The top of the extrusion telescopic rod 111 is fixedly installed at the bottom of the shielding plate 103. The extrusion spring 112 is fixedly installed inside the extrusion telescopic rod 111. The end of the extrusion telescopic rod 111 away from the shielding plate 103 is fixedly installed with an arc-shaped clamping plate 113. Through the rotation of the shielding plate 103 mentioned above, the extrusion telescopic rod 111 can be driven to rotate, and at the same time, the arc-shaped clamping plate 113 will also rotate, so that the arc-shaped clamping plate 113 pushes the rope in the hook 9. When the rope is pushed to fit with the inner wall of the hook 9 and cannot be pushed anymore, the force of the extrusion spring 112 resetting always pushes the arc-shaped clamping plate 113 to clamp the rope, so that the rope in the hook 9 can be clamped to prevent it from shaking during movement and causing the aluminum block to fall off, thus injuring people.

[0024] Working principle: After hanging the fixed aluminum block rope into the hook 9, start the winding mechanism 5, which can wind the steel wire rope 6, and at the same time drive the mounting plate 7 to drive the hook 9 to move upward. When the hook 9 moves upward, because there is a heavy object hanging, the hook 9 will slide downward in the fixed column 8, and the return spring 101 is compressed. At this time, the rotating rod 102 will move downward, and at the same time, the eccentric column 104 will also move downward. However, the force of the return of the moving spring 107 will cause the moving telescopic rod 106 to pull the hollow rod 105 to rotate upward, so that the eccentric column 104 can drive the rotating rod 102 to rotate. The hook 9 continues to move downward, and the eccentric column 104 will not rotate at this time. At this time, the hollow rod 105 will drive the moving telescopic rod 106 to stretch, and the moving spring 107 will stretch. When the rotating rod 102 rotates, it will cause the baffle plate 103 to block the notch of the hook 9, which can prevent the rope from being unhooked and thus injuring the operator.

[0025] Through the rotation of the baffle plate 103 described above, the extrusion telescopic rod 111 can be driven to rotate, and at the same time, the arc-shaped clamping plate 113 will also rotate, so that the arc-shaped clamping plate 113 pushes the rope in the hook 9. When the rope is pushed to fit the inner wall of the hook 9 and cannot be pushed anymore, the force of the return of the extrusion spring 112 continuously pushes the arc-shaped clamping plate 113 to clamp the rope. If the rope is relatively thick, then the extrusion telescopic rod 111 will be compressed during rotation, and the extrusion spring 112 will be compressed. In this way, the telescopic part in the hook 9 can be clamped to prevent it from shaking during movement, resulting in the aluminum block falling off and injuring people.

[0026] The above has generally described the present invention in detail. However, based on the present invention, some modifications or improvements can be made, which are obvious to those of ordinary skill in the art. Therefore, modifications or improvements made without departing from the spirit of the present invention are within the protection scope of the present invention.
