[0023] Through the above arrangement, first, the movable clamp plate 4 is detachably connected to the connecting column 5 through the buckle structure 6, so that the pipeline is held, and compared with the traditional lifting clamp which is installed by bolts, it is more convenient and fast; second, in case the buckle structure 6 is detached, the anti-drop structure can prevent the movable clamp plate 4 from being completely detached from the fixed clamp plate 3, so as to prevent the pipeline from falling.

[0024] When the lifting clamp of the application is initially used, the movable clamp plate 4 is opened outward, the upper end of the connecting column 5 is installed on the ceiling, the pipeline is placed inside the fixed clamp plate 3, the fixed clamp plate 3 is basically semicircular, and the inside of the fixed clamp plate 3 can be attached to the outer wall of the pipeline; the width of the hook plate 9 is smaller than the width of the pull plate 8, the included angle between the hook plate 9 and the pull plate 8 is zero, the movable clamp plate 4 is folded upward, the movable clamp plate 4 is basically semicircular, the pipeline is held, the upper end of the movable clamp plate 4 is detachably connected to the lower end of the connecting column 5 through the buckle structure 6, so as to prevent the movable clamp plate 4 from being opened, the buckle structure can refer to the cup cover structure of a snap cup, the pull plate 8 penetrates through the through hole 7, so that the hook plate 9 moves to the side of the connecting column 5 away from the movable clamp plate 4, the hook plate 9 is rotated, the hook plate 9 is rotated to the side of the pull plate 8, as shown in the drawings, the included angle b between the hook plate 9 and the pull plate 8 is forty-five degrees, at this time, the limiting protrusion 10 abuts against the side of the hook plate 9 away from the movable clamp plate 4, so as to prevent the hook plate 9 from continuing to rotate outward, the end of the hook plate 9 extends out of the pull plate 8, the hook plate 9 forms an inverted hook structure, in case the buckle structure 6 is shaken off due to vibration in subsequent pipeline work, when the movable clamp plate 4 rotates downward, the hook plate 9 hooks the connecting column 5, so as to prevent the pull plate 8 from being pulled out of the through hole 7, and further prevent the movable clamp plate 4 from being further opened downward, and further prevent the pipeline from falling. Figures 1 to 3

[0025] As an implementation manner, the buckle structure 6 comprises a buckle block 61 and a buckle body 62, the buckle block 61 is fixedly connected to the front side or the rear side of the connecting column 5, one end of the buckle body 62 is fixedly connected to the upper end of the movable clamp plate 4, and the other end is clamped with the buckle block 61.

[0026] ​The buckle body 62 of the present application is made of metal material and has good elasticity and strength. The buckle body 62 specifically includes a connecting portion and a hook portion. The connecting portion is fixedly connected to the rear end of the movable clamping plate 4. The hook portion is arranged at the front end of the connecting portion. The front end of the connecting portion is provided with an inclined surface. When the movable clamping plate 4 is folded upward, the buckle body 62 moves close to the clamping block 61. After the clamping block 61 comes into contact with the inclined surface, the buckle body 62 elastically deforms outward. After the inclined surface passes through the clamping block 61, the buckle body 62 rebounds. The hook portion hooks the clamping block 61, and the clamping is completed. When it is necessary to open the movable clamping plate 4, the buckle body 62 is manually pried outward. After the hook portion is disengaged from the clamping block 61, the movable clamping plate 4 can be opened downward.

[0027] As an implementation manner, the connecting column 5 is provided with the buckle structure 6 on both sides thereof.

[0028] Through the above arrangement, the clamping strength between the movable clamping plate 4 and the connecting column 5 is increased, and the anti-seismic performance is further improved.

[0029] As an implementation manner, the anti-disengagement structure further includes a rotating shaft 11 and a torsional spring (not shown in the figure). The rotating shaft 11 is fixedly connected to the pull plate 8. The rotating shaft 11 penetrates through the hook plate 9 and is rotatably connected to the hook plate 9. The torsional spring is arranged between the rotating shaft 11 and the hook plate 9 and applies a torque to the hook plate 9 in a direction opposite to the rotation of the movable clamping plate 4.

[0030] Through the above arrangement, the installation of the lifting clamp is further facilitated.

[0031] Before the movable clamping plate 4 is folded, the hook plate 9 is automatically abutted against the limiting protrusion 10 under the action of the torsional spring. At this time, the included angle between the hook plate 9 and the pull plate 8 is forty-five degrees. When the movable clamping plate 4 is folded, the included angle between the hook plate 9 and the pull plate 8 does not need to be considered. After the end portion of the pull plate 8 enters the through hole 7, the hook plate 9 comes into contact with the hole wall of the through hole 7. The pull plate 8 continues to move into the through hole 7. The hole wall of the through hole 7 extrudes the hook plate 9. The hook plate 9 is disengaged from the limiting protrusion 10. The included angle between the hook plate 9 and the pull plate 8 is reduced. The torsional spring is twisted. When the hook plate 9 passes through the through hole 7, the torsional spring automatically rebounds. The included angle between the hook plate 9 and the pull plate 8, which is originally a right angle, returns to forty-five degrees. The hook plate 9 automatically abuts against the limiting protrusion 10 again, as shown in FIG. 6. Figure 3

[0032] As an implementation manner, the cross section of the connecting column 5 is in an elliptical shape. The long axis direction of the cross section of the connecting column 5 is perpendicular to the length direction of the pull plate 8.

[0033] Through the above arrangement, the through hole 7 is conveniently machined at the lower end of the connecting column 5.

[0034] As an implementation manner, the upper end of the connecting column 5 is horizontally fixedly connected to a connecting plate 12. The connecting plate 12 is provided with a plurality of mounting holes 13 in the circumferential direction.

[0035] ​Through the above setting, the upper end of the connecting column 5 is conveniently installed on the ceiling.

[0036] Expansion bolts can be passed through the mounting holes 13 of the present application, and the connecting plate 12 is installed on the ceiling by using the expansion bolts.

[0037] As an implementation manner, the lower end of the fixed clamping plate 3 is hinged to the lower end of the movable clamping plate 4 through a hinge 14.

[0038] It should be understood that for those skilled in the art, improvements or changes can be made according to the above description, and all these improvements and changes shall belong to the protection scope of the appended claims of the present application.
