Description
Technical field
The utility model relates to a kind of drilling cramp fastening devices, belongs to the commercial plant field.
Background technology
When carrying out the operation of high mast rig, general normal employing has the drilling cramp of wire rope, because drilling cramp itself has certain height, therefore overhead swing is serious, location difficulty, and wire rope is stressed big.Because the stressed big discontinuity that therefore usually causes of wire rope, friction is serious, has caused potential safety hazard.
The utility model content
According to above deficiency of the prior art, the technical problem that the utility model will solve is: provide that stressed even, the overhead amplitude of fluctuation of a kind of wire rope is minimum, the drilling cramp fastening devices of support body matching coordinative.
The utility model solves the technical scheme that its technical problem adopted:
Described drilling cramp fastening devices comprises 2 right-angled trapezium set bolts, 2 U-shaped set bolts, 2 cylindrical steady pin and 4 nuts that are complementary with cylindrical steady pin size that end is taper; Said 2 right-angled trapezium set bolts are measure-alike, and its top offers through hole; Said 2 U-shaped set bolts are measure-alike, and its U-shaped internal upper part offers through hole; Cylindrical steady pin upper and lower respectively is provided with screw thread, and cylindrical steady pin external diameter and through hole internal diameter adapt, and all clear size of opening are identical.
During use; 2 right-angled trapezium set bolts are welded on the drilling cramp from top to bottom successively, and trapezoidal base and support body weld together, and keep parallel up and down; Make 2 right-angled trapezium set bolts have identical center line; 1 cylindrical steady pin is inserted in the through hole of 2 right-angled trapezium set bolts, last on cylindrical steady pin the outside of two through holes, last jack panel gets final product.
2 U-shaped set bolts are welded on the drilling cramp bottom from left to right successively; U-shaped opening edge and support body weld together; Keep the left and right sides parallel, make 2 U-shaped set bolts have identical center line, 1 cylindrical steady pin is inserted in the through hole of 2 U-shaped set bolts; Last on cylindrical steady pin the outside of two through holes, last jack panel gets final product.
The beneficial effect that the utility model had is:
Simple in structure, the good stability of the utility model has alleviated the wearing and tearing to rig and wire rope, has guaranteed operating personnel's safety.
Description of drawings
Fig. 1 is the utility model structural representation;
1-a is a right-angled trapezium set bolt structural representation;
1-b is a U-shaped set bolt structural representation;
1-c is cylindrical steady pin structural representation.
Among the figure: 1, right-angled trapezium set bolt; 2, right-angled trapezium set bolt through hole; 3, U-shaped set bolt; 4, U-shaped set bolt through hole; 5, cylindrical steady pin; 6, nut.
The specific embodiment
Below in conjunction with accompanying drawing the embodiment of the utility model is done and to further describe:
As shown in Figure 1, described drilling cramp fastening devices comprises cylindrical steady pin 5 and 4 nuts 6 that are complementary with cylindrical steady pin 5 sizes that 3,2 ends of 1,2 U-shaped set bolts of 2 right-angled trapezium set bolts are taper; Said 2 right-angled trapezium set bolts 1 are measure-alike, and its top offers through hole 2; Said 2 U-shaped set bolts 3 are measure-alike, and its U-shaped internal upper part offers through hole 4; Cylindrical steady pin 5 upper and lowers respectively are provided with screw thread, and cylindrical steady pin 5 external diameters and through hole internal diameter adapt, and all clear size of opening are identical.
In the present embodiment, right-angled trapezium set bolt 1 uses the thick iron plate of 20mm to make with U-shaped set bolt 3, and cylindrical steady pin 5 uses diameter to make as the round steel of 28mm.
During use; 2 right-angled trapezium set bolts 1 are welded on the drilling cramp from top to bottom successively, and trapezoidal base and support body weld together, and keep parallel up and down; Make 2 right-angled trapezium set bolts 1 have identical center line; Cylindrical steady pin 5 is inserted in the through hole 2 of 2 right-angled trapezium set bolts 1, last on cylindrical steady pin 5 outside of two through holes 2, last jack panel 6 gets final product.
2 U-shaped set bolts 3 are welded on the drilling cramp bottom from left to right successively; U-shaped opening edge and support body weld together; Keep the left and right sides parallel, make 2 U-shaped set bolts 3 have identical center line, cylindrical steady pin 5 is inserted in the through hole 4 of 2 U-shaped set bolts 3; Last on cylindrical steady pin 5 outside of two through holes 4, last jack panel 6 gets final product.
The utlity model has good stability, alleviated wearing and tearing, guaranteed operating personnel's safety rig and wire rope.
