Description

Technical Field

[0001] The utility model relates to the technical field of hoisting equipment, in particular to a hoisting device for a walnut shell filter. Background Technique

[0002] A filter is a separation device developed based on the principle of filtration separation. It uses an oil-resistant filter material - special walnut shells as the filtering medium. Utilizing the characteristics of large specific surface area, strong adsorption force, and large sewage interception capacity of walnut shells, it removes oil and suspended solids in water. Due to the property of being hydrophilic but not lipophilic, walnut shell filters are widely used in onshore and offshore oilfields, petrochemical, and metallurgical oil-containing sewage treatment.

[0003] The existing Chinese utility model patent with the reference publication number: CN205820673U discloses a hoisting device, including: a suspension bracket; a lifting cylinder, each of the lifting cylinders is respectively connected with a first air pipe, and they act sequentially with a time delay from one end to the other end of the suspension bracket during operation; suction cups, corresponding to each of the lifting cylinders, each of the suction cups is respectively connected with a second air pipe; a pulley mechanism, the lifting end of the steel wire rope is connected to the suction cup from the top, and the lifting cylinder drives the suction cup to move up and down; a control valve for controlling the on-off state of the first air pipe. This hoisting device can hoist the main beam on the top surface of the main beam and quickly and simply realize mold removal. While meeting the hoisting function, it will not affect any other objects in the side and bottom areas of the main beam product, thus solving a series of problems existing in the existing hoisting devices and having significant economic benefits.

[0004] Since the center of the walnut shell filter is cylindrical and the upper and lower ends are hemispherical structures, it is impossible to quickly fix the filter during the hoisting process. At the same time, during the hoisting process, the contact area between the hoisting device and the filter is small, and the filter may shake after being lifted because the relative friction force between the hoisting device and the filter is small.

[0027] The bottom end of the connecting ring 11 is provided with an annular convex structure, and the annular convex structure at the bottom end of the connecting ring 11 is located below the connecting plate 1. The fixing ring 12 is installed in an "X" shape below the connecting plate 1 at an equal 90-degree angle with the center of the connecting plate 1 as the reference.

[0028] The connecting plate 1 and the load-bearing chain 13 form a movable connection through the fixing ring 12, and the lower end of the load-bearing chain 13 and the protective frame 14 form a fixed connection through the fixing ring 12. The load-bearing chain 13 is installed in an "X" shape between the connecting plate 1 and the protective frame 14.

[0029] The connecting holes 15 are symmetrically arranged on the front and rear sides of the protective frame 14 in the front-back and up-down directions with the center of the protective frame 14 as the reference. The limiting frames 16 are symmetrically installed on the front and rear sides of the protective frame 14 in the front-back direction with the center of the protective frame 14 as the reference in a mirror image manner.

[0030] An opening structure for fitting with the adjusting piston 18 is provided at the center of the limiting frame 16. The limiting frames 16 are symmetrically arranged on the front and rear sides of the protective frame 14 in the front-back and up-down directions with the center of the protective frame 14 as the reference in a mirror image manner.

[0031] One end of the adjusting piston 18 penetrates between the support frame 17 and is fixedly connected. The limiting plates 19 are symmetrically installed on the movable ends of the adjusting pistons 18 on the front and rear sides of the protective frame 14 in a mirror image manner.

[0032] The limiting plate 19 has an arc-shaped structure. The limiting plate 19 is movably connected to the protective frame 14 through the adjusting piston 18. The spherical support plates 111 are symmetrically installed on the lower ends of the limiting plates 19 on the front and rear sides inside the protective frame 14 in a mirror image manner.

[0033] Specifically, the connecting plate 1 can limit the position of the upper end of the load-bearing chain 13. The connecting ring 11 can facilitate the connection between the connecting plate 1 and the crane hook. The fixing ring 12 can limit the positions of the upper and lower ends of the load-bearing chain 13. The load-bearing chain 13 can facilitate the movable connection between the protective frame 14 and the connecting plate 1. The protective frame 14 can protect the filter during the process of lifting the filter. The connecting hole 15 can limit the position of the adjusting piston 18. The limiting frame 16 can limit the position of the end of the adjusting piston 18. The support frame 17 can support the adjusting piston 18. The adjusting piston 18 can adjust the distance between the limiting plates 19. The limiting plate 19 can limit the position of the filter. The rubber plate 110 can increase the friction between the limiting plate 19 and the filter. The spherical support plate 111 can support the filter.

[0034] During use, one end of the adjusting piston 18 penetrates through and is fixedly connected between the support frame 17 and the limiting frame 16. At the same time, the adjusting piston 18 is symmetrically installed on the front and rear sides of the protection frame 14 through the connection holes 15 in a front-back mirror image manner. The limiting plates 19 are symmetrically installed on the movable ends of the adjusting pistons 18 on the front and rear sides of the protection frame 14 in a front-back mirror image manner. The limiting plates 19 are of an arc surface structure. The limiting plates 19 are movably connected to the protection frame 14 through the adjusting pistons 18. When fixing the filter to the hoisting device, the distance between the limiting plates 19 is adjusted through the adjusting pistons 18, so that the limiting plates 19 clamp the cylindrical outer shell of the filter. At the same time, the spherical support plates 111 are symmetrically installed on the lower ends of the limiting plates 19 on the front and rear inner sides of the protection frame 14 in a front-back mirror image manner. The spherical support plates 111 will move to the bottom end of the filter and fit with the spherical structure at the bottom end of the filter to support the filter. This method can quickly connect the filter to the hoisting device. The rubber plate 110 is fixedly installed on the inner side of the limiting plate 19. Since the limiting plate 19 is of an arc surface structure, when the limiting plate 19 clamps the cylindrical outer shell of the filter, the rubber plate 110 is located between the outer shell of the filter and the limiting plate 19. The rubber plate 110 will deform under the extrusion of the limiting plate 19 and the outer shell of the filter. And because the rubber material has a large coefficient of friction, the relative friction force between the filter and the limiting plate 19 is increased. This method can avoid the situation of shaking between the filter and the hoisting device during the process of hoisting the filter.

[0035] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
