Description

Technical Field

[0001] This utility model relates to the technical field of cranes, specifically to a safety shock-absorbing pad for cranes. Background Technology

[0002] As we all know, a crane is a multi-action lifting machine that vertically lifts and horizontally moves heavy objects within a certain range. Currently, during crane operation, the crane needs to remain stable in order to carry out stable material handling operations. However, the vibration damping structure used in some existing cranes has poor vibration damping effect, which causes the crane to sway during material handling operations, reducing the efficiency of material handling operations and increasing the risk of material handling operations.

[0003] A search revealed a utility model patent in China with publication number CN218817820U: a safety shock-absorbing pad for a crane. The safety shock-absorbing pad for a crane includes: a housing; a pad disposed on one side of the housing; a compression block fixedly connected to the pad; a buffer assembly located inside the housing on one side of the compression block for buffering the pad and the compression block; the buffer assembly includes: a movable block that fits against the compression block; a slide groove that is slidably connected to the movable block, the slide groove being fixedly connected inside the housing, and one side of the movable block being connected to the slide groove through a first elastic element; and a top rod fixedly connected to one side of the compression block.

[0004] While the above solutions can achieve shock absorption, existing technical solutions still suffer from poor stability, and it is not convenient for cranes to connect with the pads. Placing the crane support legs directly on the pads is not stable enough. Therefore, a safety shock-absorbing pad for cranes is needed to improve the above problems. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this utility model provides a safety shock-absorbing pad for cranes that uses the cooperation of multiple shock-absorbing components and auxiliary buffer mechanisms to perform shock absorption and buffering operations on the adjusting column, thereby making the support column and adjusting column more stable.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution: a safety shock-absorbing pad for a crane, comprising a pad and a support column, wherein an adjusting column is slidably installed on the pad, a first connecting plate is fixedly installed on the support column, a second connecting plate is fixedly installed on the adjusting column, the adjusting column and the second connecting plate are locked together by four bolts, and a first fixing plate is fixedly installed at the bottom end of the adjusting column;

[0009] The first fixed plate and the pad are connected by four shock-absorbing components. One of the shock-absorbing components includes a second hinge seat, which is slidably connected to the pad. The first fixed plate is fixedly mounted with a first hinge seat, and a hinge rod is hinged to the first hinge seat. The end of the hinge rod away from the first hinge seat is hinged to the second hinge seat. Two first shock-absorbing springs are symmetrically fixedly mounted on the second hinge seat, and the other ends of the two first shock-absorbing springs are fixedly connected to the pad. The pad is fixedly mounted with a second fixed plate, and two limit rods are symmetrically fixedly mounted on the second fixed plate. The two first shock-absorbing springs are respectively fitted onto the two limit rods, and the second hinge seat is slidably connected to the two limit rods.

[0010] An auxiliary buffer mechanism is provided on the adjusting column;

[0011] The first fixed plate slides stably via a stabilizing component.

[0012] The pad is limited by multiple limiting components.

[0013] Preferably, the auxiliary buffer mechanism includes four second damping springs, which are symmetrically fixedly installed at the bottom of the adjusting column. The other end of each second damping spring is fixedly connected to the pad. Each second damping spring is provided with a damper, and the two ends of the damper are fixedly connected to the pad and the adjusting column, respectively.

[0014] Furthermore, the stabilizing component includes a sliding rod, which is fixedly installed at the bottom end of the first fixed plate, and a stabilizing cylinder is fixedly installed on the second fixed plate.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example

[0027] Please see Figure 1 and Figure 2A safety shock-absorbing pad for a crane includes a pad 1 and a support column 2. An adjusting column 4 is slidably installed on the pad 1. A first connecting plate 3 is fixedly installed on the support column 2. A second connecting plate 5 is fixedly installed on the adjusting column 4. The adjusting column 4 and the second connecting plate 5 are locked together by four bolts 6. By rotating the four bolts 6 in sequence, the second connecting plate 5 and the first connecting plate 3 are connected. A first fixing plate 7 is fixedly installed at the bottom end of the adjusting column 4.

[0028] Please see Figure 1-4 The first fixed plate 7 and the pad 1 are connected by four shock-absorbing components. One of the shock-absorbing components includes a second hinge seat 10, which is slidably connected to the pad 1. A first hinge seat 8 is fixedly installed on the first fixed plate 7, and a hinge rod 9 is hinged to the first hinge seat 8. The end of the hinge rod 9 away from the first hinge seat 8 is hinged to the second hinge seat 10. Two first shock-absorbing springs 11 are symmetrically fixedly installed on the second hinge seat 10, and the other ends of the two first shock-absorbing springs 11 are fixedly connected to the pad 1. A second fixing plate 14 is fixedly installed on the pad 1. Two limiting rods 15 are symmetrically fixedly installed on the second fixing plate 14. Two first damping springs 11 are respectively fitted on the two limiting rods 15. The second hinge seat 10 is slidably connected to the two limiting rods 15. The adjusting column 4 is pressed by the support column 2. Thus, through the cooperation of multiple hinge rods 9 and multiple second hinge seats 10, multiple second hinge seats 10 slide on multiple limiting rods 15 respectively, and multiple first damping springs 11 are compressed.

[0029] Please see Figure 3 and Figure 4 An auxiliary buffer mechanism is provided on the adjusting column 4, which works in conjunction with the corresponding auxiliary buffer mechanism to compress and assist in shock absorption, thereby stabilizing the adjusting column 4 and making the support column 2 and adjusting column 4 more stable. Multiple limiting components are used to stabilize and limit the pad 1. The auxiliary buffer mechanism includes four second shock-absorbing springs 12, which are symmetrically fixedly installed at the bottom of the adjusting column 4. The other end of each second shock-absorbing spring 12 is fixedly connected to the pad 1. Each second shock-absorbing spring 12 is provided with a damper 13. The two ends of the damper 13 are fixedly connected to the pad 1 and the adjusting column 4 respectively. When the adjusting column 4 moves, the corresponding second shock-absorbing spring 12 and damper 13 are compressed or extended, thereby buffering and stabilizing the adjusting column 4.

[0030] Please see Figure 2The first fixed plate 7 is slidably operated by a stabilizing component, which includes a sliding rod 16. The sliding rod 16 is fixedly installed at the bottom end of the first fixed plate 7. A stabilizing cylinder 17 is fixedly installed on the second fixed plate 14. The sliding rod 16 is slidably connected to the second fixed plate 14 and the stabilizing cylinder 17 respectively. The sliding rod 16 makes the adjustment column 4 and the first fixed plate 7 more stable when they move.

[0031] Please see Figure 1-3 It should also be noted that the pad 1 is limited by multiple limiting components, one of which includes a mounting plate 18. The mounting plate 18 is fixedly installed on the outer wall of the pad 1. A rod 19 is slidably installed on the mounting plate 18. A screw 20 is screwed onto the mounting plate 18. A base plate 21 is fixedly installed at the bottom end of the screw 20. By hammering the rod 19, the rod 19 is connected to the ground. By rotating the screw 20, the base plate 21 gradually comes into contact with the ground, thereby making the pad 1 more stable.

[0032] Please see Figure 1-3 Two rubber pads 22 are symmetrically fixed at the bottom of the pad 1, which increases the friction of the pad 1.

[0033] In summary, when using the safety shock-absorbing pad for this crane, the second connecting plate 5 and the first connecting plate 3 are connected by rotating the four bolts 6 in sequence, making the pad 1 fit against the ground. When the ground is soil, multiple insert rods 19 can be hammered into the ground, and multiple screws 20 are rotated in sequence to make multiple base plates 21 fit against the ground, thus making the pad 1 more stable. When the ground is made of materials such as lime, the support and limit can be directly achieved by rotating the screws 20 and the base plates 21. The support column 2 applies pressure to the adjusting column 4, and through the cooperation of multiple hinge rods 9 and multiple second hinge seats 10, the multiple second hinge seats 10 slide on multiple limit rods 15, causing multiple first shock-absorbing springs 11 to compress, and the corresponding second shock-absorbing springs 12 and dampers 13 to cooperate in compression, assisting in shock absorption, thereby providing shock absorption and buffering for the adjusting column 4, making the support column 2 and the adjusting column 4 more stable, and making the crane more stable.
