Both sides of the connecting arm 15 can be detachably connected with screw rods 23, cross rods 24 are fixed between the upper parts of the two screw rods 23 through bolts, and in an initial state, the cross rods 24 are hung on the hooks 13. The below of linking arm 15 is provided with positioning disk 21, two screw rods 23 and positioning disk 21 bolt fixed connection, screw thread fixedly connected with connecting plate 22 on the screw rod 23, and the regulation hole has all been opened on the upper portion and the lower part of connecting plate 22, and regulation hole female connection has the bolt, has a plurality of fixed orificess along its vertical division on linking arm 15, and when regulation hole and fixed orifices were aligned, the bolt stretched into in regulation hole and the fixed orifices, and the connection can be dismantled on linking arm 15 to screw rod 23.
The lower part bolt fixedly connected with clamping part of first centre gripping arm 11 and second centre gripping arm 12, in this embodiment, clamping part includes that longitudinal section is the fixed block 16 of U-shaped, and the U-shaped groove has all been opened to the both sides of fixed block 16, and the U-shaped inslot rotation is connected with holder 17, and it has a plurality of centre gripping grooves 171 to open on the holder 17, and centre gripping groove 171 is the arc, and the radian inequality of centre gripping groove 171. In the present embodiment, the arc of the holding groove 171 gradually decreases or increases in the counterclockwise direction of the circumferential direction of the holding member 17. A cushion layer made of an elastic material such as rubber is adhesively fixed in the holding groove 171.
The specific implementation process is as follows:
as shown in fig. 1, in an initial state, the two screws 23 are hung on the hook 13 through the cross rod 24, and since the two screws 23 are detachably connected to the connecting arm 15, the cross rod 24 has a certain supporting effect on the hook 13, and the hook 13 moves upward for a certain distance, so that the hook 13 drives the lifting rope 14 to pull the first clamping arm 11 and the second clamping arm 12 to open. The clamping body is hung on the hook 13 through the cross rod 24, so that the whole clamping tool can move along with the hook 13.
When clamping the cylinder 31, the operator adjusts the vertical position of the connecting plate 22 to adjust the vertical position of the screw 23, and then adjusts the vertical position of the positioning plate 21 to position the clamping position of the cylinder 31. When the cylinder 31 is clamped, the center of the cylinder 31 is aligned with the positioning plate 21 in advance, then the hook 13 is moved downwards, the hook 13 is separated from the cross rod 24, the hook 13 is staggered from the cross rod 24, finally the hook 13 drives the lifting rope 14 to move upwards, the lifting rope 14 drives the first clamping arm 11 and the second clamping arm 12 to rotate towards the positioning plate 21, and the first clamping arm 11 and the second clamping arm 12 drive the fixing block 16 and the clamping piece 17 to move towards the cylinder 31 until the clamping groove 171 is abutted against the side face of the cylinder 31. When the clamping groove 171 is abutted against the side surface of the cylinder 31, the cushion layer is deformed to a certain extent under the extrusion action of the clamping groove 171 and the cylinder 31, so that the friction force between the clamping groove 171 and the cylinder 31 is increased, and the clamping stability is improved. Because the clamping pieces 17 are positioned on two sides of the fixing block 16, the clamping pieces 17 clamp the cylinder 31 from a plurality of positions, so that the clamping grooves 171 and the cylinder 31 are in line-surface contact, the clamping acting force of the clamping pieces 17 on the side surface of the cylinder 31 is concentrated, and the clamping stability is improved. In this embodiment, can select different centre gripping grooves 171 according to the diameter of cylinder 31, only need rotate holder 17 on fixed block 16, select different centre gripping grooves 171 to carry out the centre gripping according to the cylinder 31 of different diameters, reach self-adaptation's purpose, so, can overcome the problem of frequently changing anchor clamps, improve the conveying efficiency of cylinder 31.
Example two:
the second embodiment is different from the first embodiment in that, as shown in fig. 5 and 6, the holder 17 includes a rotation shaft 172 and a holding portion, and a holding groove 171 is provided in a circumferential direction of the holding portion. The lower portion of the rotating shaft 172 is rotatably connected with the fixed block 16, the rotating shaft 172 is provided with a plurality of sliding blocks 173 along the circumferential direction thereof, the sliding blocks 173 are horizontally slidably connected with the rotating shaft 172, an elastic member is arranged between the sliding blocks 173 and the rotating shaft 172, in this embodiment, the elastic member is a spring 175, one end of the spring 175 is welded on the sliding blocks 173, the other end of the spring 175 is welded on the rotating shaft 172, and one side of the sliding blocks 173 away from the spring 175 is provided with an inclined surface. The fixed block 16 is provided with a plurality of sliding grooves 174, the number of the sliding grooves 174 is the same as that of the sliding blocks 173, and the sliding blocks 173 are positioned in the sliding grooves 174.
The specific implementation process is as follows:
when the clamping grooves 171 with different radians are selected, an operator can rotate the rotating shaft 172, for example, one sliding block 173, the rotating shaft 172 drives the sliding block 173 to rotate, the inclined surface of the sliding block 173 abuts against the sliding groove 174, the sliding block 173 extends into the rotating shaft 172 under the extrusion action, then the rotating shaft 172 drives the sliding block 173 to align with the other sliding groove 174, and the sliding block 173 extends into the other sliding groove 174 under the action of the spring 175. Of course, the slider 173 may be pushed directly into the rotating shaft 172, so that the rotating shaft 172 may rotate.
When the clamping portion clamps the cylinder 31, since the sliding block 173 extends into the sliding groove 174, the rotating resistance of the rotating shaft 172 and the clamping portion is increased, the stability of clamping the cylinder 31 by the clamping portion and the clamping groove 171 is improved, and the clamping groove 171 with different radians can be conveniently selected by an operator.
The foregoing is merely an example of the present invention and common general knowledge in the art of specific structures and/or features of the invention has not been set forth herein in any way. It should be noted that, for those skilled in the art, without departing from the structure of the present invention, several changes and modifications can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicability of the patent. The scope of the claims of the present application shall be determined by the contents of the claims, and the description of the embodiments and the like in the specification shall be used to explain the contents of the claims.
