Description

Technical Field

[0001] The invention belongs to the technical field of lifting equipment, and in particular relates to a lifting equipment with an anti-slip protection mechanism. Background Art

[0002] Bridge cranes are lifting equipment widely used in the industrial field. They are mainly used for lifting materials above workshops, warehouses and material yards. Both ends of the bridge are directly supported on the elevated track through running devices. The bridge crane consists of a bridge, a lifting trolley and electrical equipment, and can run longitudinally along the tracks laid on the elevated tracks on both sides.

[0003] At present, cranes usually use hooks for lifting. In order to ensure the stability of the lifting work, a lobster buckle structure is usually added to the hook to prevent the hook from separating from the hoisted object. When lifting the object, the lobster buckle will deflect toward the inside of the hook. After the lifting preparation work is completed, the lobster buckle will rebound to lock it. Because the lobster buckle deflects toward the inside of the hook, the use space of the hook will be limited, making it difficult to insert the lifting part of some objects into the hook.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. In the present invention, the lifting part of the object is placed in the hook, and the operating handle pushes the retaining ring upward, so that the retaining ring drives the sliding ring to slide in the slideway in the hook, and then the end of the retaining ring is stuck in the embedding groove on one side of the hook. During the movement of the retaining ring, the card block in the locking assembly is squeezed, and the inclined surface position of the card block is compressed, so that it can move upward in the groove and squeeze the telescopic rod and the second spring through the extension plate. When the end of the retaining ring is completely stuck in the embedding groove, the extension plate is squeezed by the elastic force of the second spring, so that the telescopic rod drives the card block to move downward through the extension plate, so that the bottom end of the card block can be stuck in the card groove outside the retaining ring, thereby achieving the purpose of locking the retaining ring position, and then the lifting part of the object can be locked by the hook and The retaining ring is used for protection and has a good anti-slip effect. When removing the object from the hook, lift the handle so that the handle drives the extension plate to move upward, and the extension plate drives the card block to move upward to disengage it from the card slot outside the retaining ring, so that the locking state of the retaining ring can be released. Under the pulling force of the first spring in the slide slot, the guide rod will drive the retaining ring to slide in the slideway, so that the top of the retaining ring quickly disengages from the embedded slot. At this time, the retaining ring is located outside the hook and will not interfere with the operation of taking and placing objects, thereby facilitating the removal of the object from the hook. Therefore, the traditional lobster buckle structure is abandoned to prevent the hook from being separated from the hoisted object, so that the use space of the hook will not be limited, the convenience of disassembly and assembly of objects is improved, and the lifting equipment has wide versatility.

[0015] 2. In the present invention, the bottom of the lifting assembly is installed on the top of the support seat, and the mounting sleeve in the lifting assembly is supported by the bolt member at the top of the support seat, so that the mounting sleeve can rotate outside the bolt member, thereby improving the flexibility of adjusting the angle of the support seat. The mounting sleeve can be removed conveniently by removing the bolt member at the top, so as to facilitate the replacement of the steel cable or the support seat. A limit seat is added between the two ear plates, and the limit seat is used to assemble the mounting assembly and the hook, so that the hook is always in the center of the support seat, thereby improving the lifting stability. When removing the hook, loosen the locking nut on the top to disengage it from the stud in the mounting assembly, and then pull it downward. The hook and the mounting assembly are removed to facilitate replacement of the hook. When installing the hook, hold the hook and pass the mounting assembly through the limit seat so that the stud extends above the limit seat, put the sliding gasket on the outside of the stud, and then lock the stud with the locking nut to improve the convenience of installing the hook. Because the sliding column in the mounting assembly passes through the limit seat, the sliding column can rotate inside the limit seat, and the setting of the sliding gasket can reduce the friction when the sliding column rotates, so that the angle of the hook can be adjusted, and the mounting assembly and the locking nut rotate synchronously when the hook rotates, so as to facilitate the subsequent lifting of the object and improve the flexibility of use.

[0026] The mounting sleeve 402 is sleeved on the outside of the upper bolt member 502. Removing the top bolt member 502 makes it convenient to remove the mounting sleeve 402, so as to replace the steel cable 401 or the support seat 5. A fixed shaft 503 is installed in the middle of the two ear plates 501. The fixed shaft 503 and the fixed shaft 503 are provided with a limit seat 504. The limit seat 504 is located between the two ear plates 501. The top of the mounting component 6 passes through the limit seat 504. By adding a limit seat 504 between the two ear plates 501, the limit seat 504 is used to assemble the mounting component 6 and the hook 8, so that the hook 8 is always in the center of the support seat 5, thereby improving the lifting stability.

[0027] The support seat 5 is provided with a mounting assembly 6, which includes a connecting column 601, the bottom end of which is fixedly connected to the top end of the hook 8, the top end of which is fixedly connected to a sliding column 602, which passes through a limiting seat 504, the top end of which is fixedly connected to a stud 603, a locking nut 7 is threadedly connected to the outside of the stud 603, a sliding gasket 604 is connected to the outer sleeve of the stud 603, and the sliding gasket 604 is located between the locking nut 7 and the limiting seat 504. Since the sliding column 602 passes through the limiting seat 504, the sliding column 602 can rotate inside the limiting seat 504, and the setting of the sliding gasket 604 can reduce the friction force when the sliding column 602 rotates, so as to facilitate the flexible adjustment of the angle of the hook 8.

[0028] The top of the mounting assembly 6 is threadedly connected with a locking nut 7, and the stud 603 extends to the top of the limit seat 504. The sliding gasket 604 is sleeved on the outside of the stud 603, and then the stud 603 is locked by the locking nut 7 to improve the convenience of installing the hook 8. The bottom end of the mounting assembly 6 is fixedly connected with the hook 8, and slideways 10 are respectively provided on both sides of the bottom of the hook 8. An anti-slip assembly 9 is slidably connected in the slideway 10, and a slide groove 11 is provided on one side of the inner wall of the slideway 10. One end of the anti-slip assembly 9 is slidably connected in the slide groove 11, and embedded grooves 14 are respectively provided on both sides of the hook 8. The other end of the anti-slip assembly 9 is clamped in the embedded groove 14, and the inner wall of the embedded groove 14 A groove 13 is provided on the top of the retaining ring 901, and the anti-slip component 9 includes a retaining ring 901, one end of the retaining ring 901 is clamped in the embedding groove 14, and a slide bar 902 is fixed to the inner wall of the retaining ring 901, and the slide bar 902 is slidably connected in the slideway 10. The cross-sectional shapes of the slideway 10 and the slide bar 902 are both T-shaped. During the movement of the retaining ring 901, the slide bar 902 can support and limit the retaining ring 901, so that the retaining ring 901 will not fall off the hook 8, thereby improving the stability of the position adjustment of the retaining ring 901. A clamping groove 903 is provided on one side of the outer wall of the retaining ring 901, and the bottom end of the locking component 12 is clamped in the clamping groove 903, and a handle 906 is fixed on the other side of the outer wall of the retaining ring 901;

[0029] The bottom end of the retaining ring 901 is fixedly connected to a guide rod 904, and the guide rod 904 is slidably connected in the slide groove 11. A first spring 905 is fixed to the end of the guide rod 904 away from the retaining ring 901. The first spring 905 is located in the slide groove 11 and the end of the first spring 905 is fixed to the inner wall of the slide groove 11. Due to the provision of the first spring 905, under the tension of the first spring 905, the guide rod 904 will drive the retaining ring 901 to slide in the slideway 10, so that the top of the retaining ring 901 quickly disengages from the embedding groove 14. At this time, the retaining ring 901 is located outside the hook 8 and will not interfere with the operation of taking and placing objects, thereby facilitating the removal of objects from the hook 8.

[0030] A locking assembly 12 is installed in the groove 13, and the bottom end of the locking assembly 12 is clamped on the top of the anti-slip assembly 9. The locking assembly 12 includes a telescopic rod 121, and the top of the telescopic rod 121 is fixed to the top of the inner wall of the groove 13. The bottom end of the telescopic rod 121 is fixedly connected to an extension plate 123, and the bottom of the extension plate 123 is fixedly connected to a clamping block 125. The clamping block 125 is slidably connected in the groove 13, and the bottom end of the clamping block 125 is clamped on the top of the anti-slip assembly 9. One side of the clamping block 125 is designed as an inclined surface, and the other side of the clamping block 125 is designed as a plane. The clamping block 125 will be squeezed during the movement of the retaining ring 901. The inclined surface position of the clamping block 125 is compressed, so that it can move upward in the groove 13 and squeeze the extension plate 123, so that the retaining ring 901 is inserted into the embedded groove 14, which is convenient for the subsequent locking work of the retaining ring 901 by the clamping block 125.

[0031] The telescopic rod 121 is outerly connected with a second spring 122, the top of the second spring 122 is fixedly connected to the top of the inner wall of the groove 13, and the bottom end of the second spring 122 is fixed to an extension plate 123. The extension plate 123 is L-shaped and passes through one side of the inner wall of the groove 13. A handle 124 is fixed to the top of the extension plate 123. The extension plate 123 is squeezed by the elastic force of the second spring 122, so that the telescopic rod 121 drives the block 125 to move downward through the extension plate 123, so that the bottom end of the block 125 can be stuck in the slot 903 outside the retaining ring 901, which is convenient for locking the position of the retaining ring 901.

[0032] The working principle of the present invention is:

[0033] When carrying out the hoisting work, the bottom of the lifting assembly 4 is installed on the top of the supporting seat 5, and the mounting sleeve 402 in the lifting assembly 4 is supported by the bolt member 502 at the top of the supporting seat 5, so that the mounting sleeve 402 can rotate outside the bolt member 502, and then the handle 124 is lifted up, so that the handle 124 drives the extension plate 123 to move upward, and the extension plate 123 drives the clamping block 125 to move up to disengage it from the clamping groove 903 outside the retaining ring 901, so that the locking state of the retaining ring 901 can be released, and under the pulling force of the first spring 905 in the slide groove 11, the guide rod 904 will drive the retaining ring 901 to slide in the slideway 10, so that the top of the retaining ring 901 quickly disengages from the embedded groove 14, and at this time, the retaining ring 901 is located outside the hook 8, and will not interfere with the operation of taking and placing objects;

[0034] Secondly, place the hoisting part of the object in the hook 8, operate the handle 906 to push the retaining ring 901 upward, so that the retaining ring 901 drives the sliding ring to slide in the slideway 10 in the hook 8, and then the end of the retaining ring 901 is stuck in the embedding groove 14 on one side of the hook 8. During the movement of the retaining ring 901, the block 125 in the locking assembly 12 is squeezed, and the inclined surface position of the block 125 is compressed, so that it can move upward in the groove 13 and squeeze the telescopic rod 121 through the extension plate 123. and the second spring 122, the end of the retaining ring 901 is completely inserted into the embedding groove 14, and the extension plate 123 is squeezed by the elastic force of the second spring 122, so that the telescopic rod 121 drives the clamping block 125 to move downward through the extension plate 123, so that the bottom end of the clamping block 125 can be inserted into the clamping groove 903 outside the retaining ring 901, so as to achieve the purpose of locking the retaining ring 901, and then the hoisting part of the object can be protected by the hook 8 and the retaining ring 901, so as to prevent the object from falling off;

[0035] When replacing the steel cable 401 or the support seat 5, the top bolt 502 is removed to facilitate the removal of the installation sleeve 402. When removing the hook 8, loosen the locking nut 7 above to disengage it from the stud 603 in the installation assembly 6, and pull it downward to remove the hook 8 and the installation assembly 6. When installing the hook 8, hold the hook 8 to pass the installation assembly 6 through the limit seat 504 so that the stud 603 extends to the top of the limit seat 504, and set the sliding gasket 604 outside the stud 603, and then lock the stud 603 with the locking nut 7. The sliding column 602 in the installation assembly 6 passes through the limit seat 504, so that the sliding column 602 can rotate inside the limit seat 504. With the setting of the sliding gasket 604, the friction force when the sliding column 602 rotates is reduced, and when the hook 8 rotates, the installation assembly 6 and the locking nut 7 rotate synchronously, so that the angle of the hook 8 can be adjusted.
