Description

Technical Field

[0001] The utility model relates to the field of cranes, in particular to a shock-proof and pressure-resistant device for cranes. Background Art

[0002] Single-beam bridge crane is a lifting equipment that is horizontally mounted above workshops, warehouses and material yards to lift materials. Because its two ends are located on tall concrete columns or metal brackets, it looks like a bridge. The bridge of the single-beam bridge crane runs longitudinally along the tracks laid on the elevated platforms on both sides, and can make full use of the space under the bridge to lift materials without being hindered by ground equipment.

[0003] Earthquake and compression resistance are basic requirements to ensure the safe and stable operation of single-girder cranes. In production environments, especially in industrial plants or warehouses, single-girder cranes often need to undertake the task of lifting and transporting heavy objects. If the crane cannot effectively resist the impact of shaking or external pressure, its structure may be severely damaged, or even collapse and other safety accidents may occur, causing huge losses to personnel and property. Therefore, earthquake and compression resistance design is the key to ensuring the safe operation of the crane.

[0004] At present, the lifting equipment on the single-beam bridge crane is subjected to huge gravity, and the hook itself may break due to material fatigue, cracks or design defects. Its compressive resistance is poor, and the shock-absorbing capacity it can provide when bearing the huge gravity of the hoisted object is weak. Utility Model Content

DETAILED DESCRIPTION

[0028] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution in the embodiments of the utility model is described clearly and completely. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of 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.

[0029] Reference Figure 1-Figure 5 , a seismic and pressure-resistant device for a crane, comprising:

[0030] A crane 1 is connected to a wire wheel 2, both sides of the wire wheel 2 are fixedly connected with connecting plates 3, and an adjusting part 4 is connected to the two connecting plates 3; a hook 6 is installed on the wire wheel 2 for lifting goods.

[0031] Reference Figure 1 and Figure 2 The adjusting part 4 is arranged between the hook 6 and the crane 1. When the hook 6 lifts an object and moves, the shaking caused by its inertia will only stay on the adjusting part 4, avoiding the shaking force from being transmitted to the wire wheel 2 and the crane 1.

[0032] Reference Figure 1 , Figure 2 and Figure 4 The two reinforcing parts 1 61 are respectively installed on both sides of the hook 6, and one side of the two reinforcing parts 2 62 is fixedly connected with a connecting seat 65. The two reinforcing parts 2 62 are respectively fixedly installed on both sides of the hook 6 through the connecting seat 65. The reinforcing part 2 62 is rotatably connected with the corresponding reinforcing part 1 61. A monitoring part 64 is provided between the reinforcing part 1 61 and the reinforcing part 2 62 for monitoring the rotation of the reinforcing part 2 62.

[0033] The reinforcement part 1 61 and the reinforcement part 2 62 are connected and installed on the side of the hook 6, which can enhance the support and compression resistance of the hook 6 and monitor the use status of the hook 6. If the hook 6 breaks or bends, the reinforcement part 2 62 will rotate and deviate along with the end of the hook 6, and the reinforcement part 2 62 can be monitored using the monitoring part 64.

[0034] Reference Figure 3 The adjusting part 4 is arranged between the reel 2 and the hook 6. The adjusting part 4 includes a swinging ball 42 installed on the top of the buffer part 5. A spherical groove 41 is opened at the bottom of the adjusting part 4 to provide a movable space for the swinging ball 42. The swinging ball 42 can rotate at any angle in the spherical groove 41, which can be used to interrupt the hook 6 from transmitting the shaking to the reel 2.

[0035] Reference Figure 2 , Figure 3 and Figure 5 The buffer part 5 is arranged between the adjusting part 4 and the hook 6, and is used to monitor the compressive state of the hook 6. The buffer part 5 includes a buffer cavity 51. The buffer cavity 51 is spherical and has an opening at the bottom. A connecting rod 52 is installed in the buffer cavity 51. A top plate 53 and a bottom plate 54 are respectively installed at both ends of the connecting rod 52. The bottom plate 54 is connected to the hook 6. A displacement sensor 56 is installed on the top wall of the buffer cavity 51, and is used to monitor the displacement distance of the top plate 53. The spring 55 is sleeved on the outside of the connecting rod 52, and is used for buffering the hook 6.

[0036] When the hook 6 is pulled by gravity, it will drive the bottom plate 54 to move, and the bottom plate 54 will drive the connecting rod 52 and the top plate 53 to move in the buffer chamber 51. The top plate 53 squeezes the spring 55, and the spring 55 can absorb and disperse the impact force, thereby reducing the damage to the sheave 2 and the crane 1. The spring 55 can gradually absorb and disperse the external force, thereby achieving a buffering effect. The displacement sensor 56 monitors the moving distance of the top plate 53. If the weight of the lifted object is heavy, the spring 55 cannot provide a good buffer, so that the top plate 53 is far away from the displacement sensor 56, and a pressure resistance prompt and warning can be issued.

[0037] Reference Figure 4 A receiving groove 63 is provided on one side of the reinforcement part 1 61 , and the monitoring part 64 is installed in the receiving groove 63 , and the monitoring end of the monitoring part 64 is connected to the reinforcement part 2 62 .

[0038] The monitoring unit 64 uses an angle sensor, and may also use other electronic devices that can monitor displacement changes.

[0039] During use, the crane 1 controls the reel 2 and the hook 6 to fall. After the hook 6 lifts the object, the gravity of the object will pull the hook 6. The hook 6 bears a large gravity at the moment of lifting. The hook 6 drives the bottom plate 54, the connecting rod 52 and the top plate 53 to move at the same time. The top plate 53 squeezes the spring 55. The spring 55 can absorb and disperse the impact force, gradually absorb and disperse the external force, reduce the damage to the reel 2 and the crane 1 caused by the impact, and thus play a buffering effect. The displacement sensor 56 monitors the moving distance of the top plate 53. If the weight of the lifted object is heavy, the spring 55 cannot provide a good buffer, so that the top plate 53 is far away from the displacement sensor 56, which can be detected. The swing ball 42 can rotate at any angle in the spherical groove 41. When the hook 6 picks up objects and moves, the shaking caused by its inertia will only stay on the adjusting part 4, avoiding the transmission of shaking force to the wire wheel 2 and the crane 1. The reinforcement part 1 61 and the reinforcement part 2 62 can monitor the use status of the hook 6. If the hook 6 breaks or bends, the reinforcement part 2 62 will rotate and deviate with the end of the hook 6 and rotate at the end of the reinforcement part 1 61. The monitoring part 64 can monitor the angle of the reinforcement part 2 62. When it is detected that the angle of the reinforcement part 2 62 changes relative to the reinforcement part 1 61, an alarm is issued and the hook 6 is replaced in time.

[0040] In summary, compared with the prior art, the present invention has the following beneficial effects:

[0041] The use status of the hook 6 can be monitored through the reinforcement part 1 61 and the reinforcement part 2 62. When it is monitored that the angle of the reinforcement part 2 62 relative to the reinforcement part 1 61 changes, an alarm is issued and the hook 6 is replaced in time.

[0042] The swing ball 42 can be rotated at any angle in the spherical groove 41, thereby avoiding the transmission of shaking force to the wire wheel 2 and the crane 1.

[0043] The buffer part 5 can absorb and disperse the impact force brought by the hoisted objects, gradually absorb and disperse the external force, reduce the damage to the wire wheel 2 and the crane 1, and thus achieve a buffering effect. The displacement sensor 56 monitors the moving distance of the top plate 53 and issues a pressure resistance prompt and warning.
