However, the connection is processed by bolts. When disassembling and assembling to meet the length adjustment, it is necessary to apply a tightening force to the bolts one by one. The operation process is cumbersome, time-consuming, labor-intensive, and inefficient. Therefore, it is necessary to provide a hook-type shot blasting cleaning hook device that can be easily and quickly disassembled and assembled to improve the use effect. Utility Model Content

[0009] Furthermore, the connecting portion also includes a connecting ring; the lower adjusting bolt thread passes through the middle of the lower end of the connecting ring and extends to the upper end of the hook body, and the upper adjusting bolt thread passes through the middle of the upper end of the connecting ring.

[0010] Furthermore, the connecting portion further comprises a bolt block; the bolt block is fixedly connected to one end of the upper adjusting bolt, and a through-hole is formed through the middle of the upper end of the bolt block.

[0011] Furthermore, it also includes an anti-slip limit part, which includes a torsion spring, a support block, a limit rod, a control switch and a warning light; the torsion spring is symmetrically fixed on the upper inner part of the hook body, and the inner side of the torsion spring is fixed to the end of the support block, a limit rod is fixed on one side of the outer surface of the support block, the control switch is embedded in one end of the inner side of the hook body, and the warning light is embedded in one end of the outer surface of the hook body.

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] In order to make the purpose, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0026] See also Figure 1-4 As shown, the utility model is a hook device for a hook-type shot blasting cleaning machine, comprising a hook body 11;

[0027] The hook body 11 is used for hoisting the shot blasting machine.

[0028] The connecting part includes a lower adjusting bolt 22 and an upper adjusting bolt 23; the upper adjusting bolt 23 is arranged above the lower adjusting bolt 22;

[0029] The upper adjusting bolt 23 and the lower adjusting bolt 22 can be adjusted in length by using thread extension to meet the lifting requirements while being installed with the hook body 11 and the bolt block 24.

[0030] The connecting portion further includes a connecting ring 21; a lower adjusting bolt 22 is threadedly passed through the middle of the lower end of the connecting ring 21 and extends to the upper end of the hook body 11; an upper adjusting bolt 23 is threadedly passed through the middle of the upper end of the connecting ring 21;

[0031] The connecting ring 21 structurally supports and installs the lower adjusting bolt 22 and the upper adjusting bolt 23 .

[0032] The connection portion further includes a bolt block 24; the bolt block 24 is fixedly connected to one end of the upper adjustment bolt 23, and a through-hole is formed in the middle of the upper end of the bolt block 24;

[0033] The bolting block 24 can be used in conjunction with the through opening to bolt the hoisting rope on the hoisting equipment.

[0034] The convenient disassembly and assembly part includes a disassembly and assembly gear 31, a disassembly and assembly plate 32, a tooth block 35, a hole block 33 and a connecting column 34; the disassembly and assembly gear 31 is sleeved and fixed on the outer surface of the end of the lower adjusting bolt 22 and the upper adjusting bolt 23, and the tooth blocks 35 are fixed at equal intervals on the central position of the inner side of the disassembly and assembly plate 32, and the adjacent tooth blocks 35 are meshed and connected with the disassembly and assembly gear 31. The hole block 33 is sleeved in the middle of the front of the disassembly and assembly plate 32, and the upper and lower ends of the connecting column 34 extend out of the middle part of the hole block 33.

[0035] The disassembly plate 32 fixes multiple tooth blocks 35, and the hole block 33 installs and fixes the connecting column 34 to the disassembly plate 32. The length can be adjusted by setting the connecting column 34 and the hole block 33 at different upper and lower positions. The disassembly force is then applied by the connecting column 34. Through the engagement between the tooth block 35 and the disassembly gear 31, the disassembly and assembly of the upper adjusting bolt 23 and the lower adjusting bolt 22 can be completed quickly and conveniently at the same time.

[0036] Working principle: After bolting the bolt block 24 to the rope on the lifting equipment, the lifting structure on the shot blasting machine is hung with the hook body 11. At this time, if the lifting height needs to be adjusted, the spacing between a set of disassembly plates 32 can be adjusted in advance, and it can be completed by using the sleeves between different positions of the connecting column 34 and the inner wall of the hole block 33. Then, the tooth block 35 on the inner side of the disassembly plate 32 is engaged with the disassembly gear 31, and the connecting column 34 is used to apply the force required for disassembly and assembly, and the upper adjusting bolt 23 and the lower adjusting bolt 22 can be rotated synchronously.

[0037] This solution can simultaneously complete the disassembly and assembly of the upper adjusting bolt 23 and the lower adjusting bolt 22, saving time and effort, improving disassembly and assembly efficiency, and facilitating use.

[0038] See also Figure 1-4 As shown, this embodiment is based on the above-mentioned embodiment 1 and further includes an anti-slip limiter, which includes a torsion spring 41, a support block 42, a limit rod 43, a control switch 44 and a warning light 46; the torsion spring 41 is symmetrically fixed to the upper inner portion of the hook body 11, and the inner side of the torsion spring 41 is fixed to the end of the support block 42, a limit rod 43 is fixed to one side of the outer surface of the support block 42, the control switch 44 is embedded in one end of the inner side of the hook body 11, and the warning light 46 is embedded in one end of the outer surface of the hook body 11;

[0039] The torsion spring 41 satisfies the fixation of the support block 42 structure and facilitates angle adjustment and restoration of the original state after adjustment. The limit rod 43 limits the structure on the inner side of the hook body 11. After the control switch 44 conflicts with the lower end of the limit rod 43, the warning light 46 is controlled by the wire 45. The opening and closing of the warning light 46 can be used to determine whether the torsion spring 41 has failed, and timely inspection and replacement can be carried out to avoid the risk of falling off during subsequent lifting.

[0040] The output end of the control switch 44 is electrically connected to a wire 45 , and one end of the wire 45 is electrically connected to the input end of the warning light 46 ;

[0041] The wire 45 electrically connects the control switch 44 and the warning light 46 to transmit data.

[0042] The diameter of the lower end of the limiting rod 43 is larger than the outer diameter of the control switch 44, and the lower end of the limiting rod 43 is covered with a rubber sleeve and contacts the control switch 44;

[0043] The large diameter of the lower end of the limiting rod 43 is conducive to contact with the control switch 44, and the rubber sleeve can prevent the two from sliding after contact, which affects the pressing of the control switch 44.

[0044] Working principle: During the use of the limit rod 43, in the initial state, the lower end of the limit rod 43 conflicts with the control switch 44. The control switch 44 uses the wire 45 to control the warning light 46. At this time, the warning light 46 is in the light state, indicating that the elastic force of the torsion spring 41 has not failed and can be used normally. Otherwise, the torsion spring 41 needs to be replaced.

[0045] This solution effectively avoids objects from falling off during subsequent lifting, improves usage effects, and meets needs.
