Description

Technical Field

[0001] The utility model belongs to the technical field of crane hook groups, and particularly relates to a European-style bevel wheel hook group with a lubrication structure. Background Art

[0002] With the rapid development of the construction and manufacturing industries, the demand for lifting and hoisting equipment is increasing. European-style hook blocks, as crucial crane components, have a performance and quality that directly impacts the safety and efficiency of lifting operations. As a mid- to high-end hook block, European-style hook blocks utilize a unique design concept. Compared to traditional lifting hook blocks, they offer lightweight, compact construction, low energy consumption, and enhanced practicality, making them increasingly popular in the market. However, traditional hook block manufacturing processes suffer from low production efficiency, insufficient machining precision, and high costs. The name of the authorization announcement number CN203497929U is: Crane inclined pulley hook group, which reduces the angle between the wire rope and the pulley, avoids the interlacing of the wire ropes, reduces the wear of the wire rope, and increases the service life of the wire rope and the pulley group. However, the hook group will make abnormal noises due to wear between the pulley and the rotating shaft during later use. Especially for workshops with harsh production environments, the use of the hook group will be even worse, which greatly reduces the service life of the hook group. In addition, the installation of the hook group pulley shaft and the yoke plate of the utility model is through straight hole assembly. This assembly method will result in a larger gap between the pulley shaft and the yoke plate, poor sealing, and dust will enter through this gap during later use.

[0003] Therefore, it is necessary to design a hook group with a self-lubricating structure to solve the current technical problems. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a European-style hook assembly with an inclined wheel and a lubrication structure, which solves the problem of short service life of the hook assembly in harsh environments.

[0005] The technical solution of the utility model is: a bevel wheel European hook group with a lubrication structure, comprising a yoke plate, a hook body, a hook beam, a hook nut, a pulley shaft, and a pulley piece: an inclined hole is provided on the yoke plate, and both ends of the pulley shaft are assembled with the yoke plate through the inclined hole, and both ends of the pulley shaft are respectively provided with oil injection blind holes along their axial direction, a deep groove ball bearing is provided between the pulley shaft and the pulley piece, an oil outlet hole is provided between the oil injection blind hole and the deep groove ball bearing, the oil outlet hole connects the oil injection blind hole and the deep groove ball bearing, and a sealing plug is provided at the orifice of the oil injection blind hole.

[0006] Preferably, both ends of the pulley shaft are provided with square grooves, the square grooves are connected with the oil injection blind holes, and the sealing plugs are located in the square grooves.

[0007] Preferably, both ends of the pulley shaft are provided with shaft end baffles, and the shaft end baffles are fixedly connected to their corresponding yoke plates by hexagon socket head screws.

[0008] Preferably, a square hole is provided in the middle of the shaft end baffle, and the size of the square hole is larger than the size of the square groove.

[0009] Preferably, the oil outlet holes of two adjacent pulleys are alternately arranged on both sides of the pulley shaft.

[0010] Preferably, the hook body is provided with an anti-dropping clip, one end of the anti-dropping clip is hinged to the hook body, and the other end of the anti-dropping clip abuts against the hook body of the hook body.

[0011] Beneficial effects of the utility model:

[0012] The utility model has a simple structure and is easy to operate. The deep groove ball bearings of the hook assembly can be lubricated regularly to maintain the hook assembly and extend its service life. The yoke plate and the pulley shaft are assembled together through the inclined hole, which makes the fit between the yoke plate and the pulley shaft tighter and has strong sealing, which reduces dust ingress during later use.

[0019] In order to make the purpose, technical solution and beneficial effects of the present invention clearer, the embodiments of the present invention are further described in detail below with reference to the accompanying drawings.

[0020] like Figures 1 to 3As shown, a European-style helical hook assembly with a lubrication structure includes a yoke plate 1, a hook body 2, a hook crossbeam 3, a hook nut 4, a pulley shaft 5, and a pulley piece 6. The yoke plate 1 is provided with an oblique hole 16, and both ends of the pulley shaft 5 are assembled with the yoke plate 1 through the oblique hole 16. Both ends of the pulley shaft 5 are provided with oil injection blind holes 7 along their axial directions. A deep groove ball bearing 8 is provided between the pulley shaft 5 and the pulley piece 6. Figure 4 As shown, an oil outlet hole 9 is provided between the oil filling blind hole 7 and the deep groove ball bearing 8. The oil outlet holes 9 of two adjacent pulleys 6 are alternately arranged on both sides of the pulley shaft 5. This ensures that the lubricant can evenly lubricate and maintain the deep groove ball bearing 8. The oil outlet hole 9 connects the oil filling blind hole 7 and the deep groove ball bearing 8. A sealing plug 10 is provided at the opening of the oil filling blind hole 7. Both ends of the pulley shaft 5 are provided with a square groove 11, which is connected to the oil filling blind hole 7. The provision of the square groove 11 facilitates the addition of lubricant to the oil filling blind hole 7. The sealing plug 10 is located in the square groove 11 and is threadedly connected to the oil filling blind hole 7.

[0021] The ends of the pulley shaft 5 are both provided with shaft end baffles 12, and the shaft end baffles 12 are fixedly connected to the corresponding yoke plates 1 by hexagon socket head screws 13. Figure 5 、 Figure 6 As shown, preferably, a square hole 14 is provided in the middle of the shaft end baffle 12 , and the size of the square hole 14 is larger than the size of the square groove 11 .

[0022] The hook body 2 is provided with an anti-slip card 15, one end of the anti-slip card 15 is hinged to the hook body 2, and the other end of the anti-slip card 15 is in contact with the hook body of the hook body 2. The setting of the anti-slip card 15 can prevent the goods from slipping during the lifting process and improve safety.

[0023] During use, when the deep groove ball bearing 8 needs maintenance or lubricant is added to the deep groove ball bearing 8 regularly, when adding, rotate and remove the sealing plug 10, add lubricant to the square groove 11, and the lubricant flows into the deep groove ball bearing 8 through the oil filling blind hole 7 and the oil outlet hole 9 to lubricate the deep groove ball bearing 8. After adding lubricant, re-tighten the sealing plug 10 to prevent dust from falling into the oil filling blind hole 7. The operation is simple and convenient. The hook group can be maintained regularly in this way, and the service life of the hook group can be extended.

[0024] The above is a preferred embodiment of the present invention. Technical personnel in this industry should understand that the embodiment of the present invention is not limited by the above content. Any other changes, modifications, substitutions, combinations, and simplifications that do not deviate from the spirit and principles of the present invention should be equivalent replacement methods and are included in the scope of protection of the present invention.
