Detailed Description

The present application is described in further detail below with reference to figures 1-2.

The embodiment of the application discloses a coring equipment that is used for steady core of water.

Example 1

Referring to fig. 1, a coring equipment for water is got steadily includes clamping part and drive division, and the clamping part includes two grip blocks 1 that are the circular arc type setting, and the drive division is used for driving two grip blocks 1 to rotate.

Referring to fig. 1, the intrados of two grip blocks 1 set up relatively and are used for the circumference lateral wall of centre gripping core appearance, and the one end fixedly connected with fixed plate 3 of grip block 1 circumference.

The drive portion includes two articulated clamping bars 2 each other, and two clamping bars 2 are with a fixed plate 3 of the equal fixed connection in end.

The workman inserts two grip blocks 1 between drilling and the core appearance, then manually exerts the clamp force to clamping bar 2, and two grip blocks 1 cooperate and realize the centre gripping to the core appearance, and the workman can pull out the drilling with the core appearance afterwards.

The clamping plate 1 is arranged in an arc shape, so that the contact area with the core sample is increased, the possibility of damage of the core sample is reduced, and the integrity of the core sample is improved.

Simultaneously, the circular arc type sets up the static frictional force that has increased between grip block 1 and the core appearance to this workman can be more laborsaving realization core.

In the actual use process, the length of the clamping rod 2 can be properly lengthened, so that a worker can more labor-saving core taking. In addition, the clamping plate 1 can be modified by adopting a waste core drilling barrel, and the core drilling barrel is communicated with the core sample in size, so that the modification is convenient and the cost is lower.

The implementation principle of the embodiment 1 is as follows: the workman is manual to make two clamping bars 2 be close to each other to this makes two centre gripping arms 4 rotate in opposite directions, makes grip block 1 press from both sides the lateral wall of tight core appearance with this, and grip block 1 is great with the area of contact of core appearance, therefore grip block 1 is difficult to the double-layered core appearance of hindering when realizing pressing from both sides tight to the core appearance.

Example 2

Referring to fig. 2, the present embodiment is different from embodiment 1 in that the grip portion includes a plurality of grip arms 4 arranged circumferentially, and the drive portion is configured to drive the plurality of grip arms 4 to rotate.

Referring to fig. 2, the driving part further includes a mounting plate 5 which is horizontally arranged and has a circular cross section, a mounting rod 6 which is vertically and fixedly connected to the upper surface of the mounting plate 5 and is coaxially arranged with the mounting plate, and a threading block 7 which is fixedly connected to the top end of the mounting rod 6.

Referring to fig. 2, a plurality of mounting openings are uniformly formed in the outer side wall of the mounting plate 5 in the circumferential direction, one clamping arm 4 corresponds to one mounting opening and is hinged to the mounting opening, and the arm body of the clamping arm 4 above the mounting plate 5 inclines towards the direction close to the vertical center line of the mounting plate 5.

A pull ring 8 is arranged above the threading block 7, a pull wire 9 is tied at the top end of the clamping arm 4, and the pull wire 9 slides through the threading block 7 and is tied on the pull ring 8.

Referring to fig. 2, during coring, the worker inserts all the arm bodies of the clamping arms 4 below the mounting plate 5 into the core sample and the drill hole, then pulls the pull ring 8 upwards, the pull ring 8 pulls the clamping arms 4 to rotate through the pull wire 9, and then the clamping arms 4 clamp the outer side wall of the core sample, so that the worker can directly pull out the core sample from the drill hole, and the operation is convenient.

Referring to fig. 2, since the plurality of holding arms 4 are provided, the contact area with the core sample can be increased, and the possibility of damage to the core sample can be reduced.

Referring to fig. 2, the clamping surface of the clamping arm 4 is an arc surface, so that the contact area between the clamping arm 4 and the core sample is further increased, and the clamping effect of the clamping part on the core sample is favorably improved.

Referring to fig. 2, the clamping surface of the clamping arm 4 is provided with anti-slip threads 10, and the arrangement of the anti-slip threads 10 is beneficial to increasing the friction force between the clamping arm 4 and the core sample, so that the possibility of falling off of the core sample in the coring process is reduced.

Referring to fig. 2, the positions of the upper surface and the lower surface of the threading block 7, through which the pull wire 9 passes, are provided with arc chamfers (not shown in the figure), and the arrangement of the arc chamfers protects the pull wire 9, so that the possibility that the edge of the position of the threading block 7, through which the pull wire 9 passes, abrades the pull wire 9 is reduced.

Referring to fig. 2, since the grip arm 4 is disposed to be inclined closer to the arm body at the top end thereof, the arm body of the grip arm 4 located below the mounting plate 5 is inclined away from the vertical center line of the mounting plate 5 in a natural state, and thus there is a certain inconvenience in the operator inserting the grip arm 4 between the core sample and the drill hole.

Referring to fig. 2, for this purpose, the lower surface of the mounting plate 5 is bolted with a stop collar 11 coaxially disposed therewith, and when the outer side wall of the holding arm 4 is closely attached to the inner wall of the stop collar 11, the body of the holding arm 4 below the mounting plate 5 is kept vertical, so that a worker can insert a plurality of holding arms 4 between the core sample and the drill hole at the same time with relative convenience.

Referring to fig. 2, when the outer side wall of the holding arm 4 is closely attached to the inner wall of the stop ring 11, the distance from the top end of the holding arm 4 to the mounting rod 6 is smaller than the distance from the threading block 7 where the pull wire 9 passes to the mounting rod 6.

Therefore, the pull wire 9 is used for pulling the clamping arm 4, the direction of the pull force of the pull wire is vertical to the arm body of the clamping arm 4, which is positioned above the mounting plate 5, and the tensioning effect of the pull wire 9 on the clamping arm 4 is favorably improved.

The implementation principle of the embodiment 2 is as follows: the workman inserts between core appearance and the drilling with a plurality of centre gripping arms 4, then upwards stimulates pull ring 8, and pull ring 8 passes through 9 pulling centre gripping arms 4 rotations of acting as go-between, and the lateral wall of the tight core appearance of a plurality of centre gripping arms 4 cooperation clamp, and at this moment, the workman can be directly upwards pull out the drilling with the core appearance.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
