The embodiment of the application discloses a counterweight structure of a rotary drilling rig. Referring to fig. 1 and 2, a counterweight structure of a rotary drilling rig includes a counterweight table 1 and a counterweight block 2 disposed on the counterweight table 1. Both sides of the counterweight table 1 are hinged with limiting rods 11, and both sides of the counterweight block 2 are provided with gaps 21 matched with the limiting rods 11. When piling up balancing weight 2 and placing on counter weight platform 1, gag lever post 11 can rotate to the card in opening 21, produces spacing effect to balancing weight 2. The weight of the counter weight 2 itself is marked on the counter weight 2.

Referring to fig. 1 and 2, a pressing plate 3 is disposed between the two limiting rods 11, and through holes for the limiting rods 11 to pass through are formed at two ends of the pressing plate 3. An external thread is arranged on the limiting rod 11, and a pressing block 4 is connected to the limiting rod 11 through a thread. When rotating gag lever post 11 to support in opening 21 on balancing weight 2, press plate 3 is fixed with two gag lever posts 11 for gag lever post 11 can't rotate. Then, the pressing plate 3 is pressed against the balancing weight 2 by rotating the pressing block 4.

When dismantling, dismantle briquetting 4 from gag lever post 11 the back, take off clamp plate 3 from gag lever post 11, rotate gag lever post 11 for gag lever post 11 and balancing weight 2 separate, thereby expose balancing weight 2 completely, made things convenient for the staff to use machinery such as loop wheel machine to take off balancing weight 2. Meanwhile, the weight marked on the balancing weight 2 is convenient for the staff to determine the number of the balancing weights 2 which need to be taken down from the balancing weight table 1.

Referring to fig. 3 and 4, in order to make the counterweight block 2 more stable on the counterweight table 1, a through hole 22 is formed on the counterweight block 2. Two blocks 5 are slidably arranged in the through hole 22. An elastic piece is arranged between the two clamping blocks 5 and used for pulling the two clamping blocks 5 to move towards the mutually approaching direction. The counterweight block 2 is provided with a jack 23, and the jack 23 is communicated with the through hole 22. The opening direction of the insertion hole 23 and the opening direction of the through hole 22 are perpendicular to each other.

Referring to fig. 2 and 4, a jack post 6 is inserted into the insertion hole 23. When the top post 6 is inserted into the insertion hole 23, the two latch blocks 5 are moved away from each other by the force of the top post 6 and protrude from the through hole 22. The limiting rod 11 is uniformly provided with clamping grooves 12 matched with the clamping blocks 5 along the axial direction, so that the clamping blocks 5 can be inserted into the clamping grooves 12 after extending out of the through holes 22.

Referring to fig. 3 and 4, the elastic member is a spring 51, and the number of the springs 51 between the two latch blocks 5 is two. A certain gap is present between the two springs 51, ensuring that the top post 6 can pass between the two springs 51. Two ends of the spring 51 are fixedly connected with the two fixture blocks 5 respectively. When the spring 51 is in the original long state, the two latch 5 are completely received in the through hole 22.

Referring to fig. 3 and 4, in order to reduce resistance when moving the latch 5, rollers 52 are rotatably disposed at both sides of the latch 5, so that sliding friction is converted into rolling friction when the latch 5 moves in the through hole 22. On one hand, the elasticity required when the fixture block 5 is pulled to move is greatly reduced; on the other hand, the force required to eject the latch 5 from the through hole 22 is reduced.

Referring to fig. 3, in order to prevent the locking block 5 from falling off from the through hole 22, a limiting groove 24 with two closed ends is formed on the inner wall of the through hole 22. The limiting block 53 is fixedly arranged on the clamping block 5, the limiting block 53 is slidably arranged in the limiting groove 24, the movable distance of the clamping block 5 is limited by the length of the limiting groove 24, and the clamping block 5 is prevented from falling out of the through hole 22.

Referring to fig. 2 and 4, in order to facilitate the insertion of the top post 6 into the insertion hole 23 of the counterweight block 2, one end of the top post 6 is tapered, which facilitates the insertion of the top post 6 between the two fixture blocks 5. The other end of the top column 6 is fixedly provided with a flange 61, and the pressing plate 3 is provided with a containing groove 31 matched with the flange 61, so that the flange 61 can be embedded in the containing groove 31. The counterweight table 1 is provided with a positioning hole 13 through which the top column 6 passes. After the jack 6 is inserted into the jack 23, the pressing plate 3 can be used for pressing the jack 6 on the balancing weight 2, so that the firmness of the jack 6 is ensured.

Referring to fig. 1 and 2, in order to facilitate the movement of the counterweight 2 by using a machine such as a crane, hooks 25 are provided on both sides of the counterweight 2. The hook 25 and the gap 21 are located on different sides of the balancing weight 2, and the obstruction caused by the placement of the limiting rod 11 at the gap 21 of the balancing weight 2 is avoided.

The embodiment of the application also discloses a rotary drilling rig which uses the counterweight structure of the rotary drilling rig. Referring to fig. 5, the counterweight table 1 is fixedly arranged on the rotary drilling rig.

The implementation principle of the embodiment of the application is as follows: when the balancing weight 2 needs to be detached, the pressing block 4 is taken down from the limiting rods 11, and then the pressing plate 3 is taken down from the two limiting rods 11. The top pillar 6 is pulled out from the balancing weight 2, and after the top pillar 6 is pulled out, the fixture block 5 is separated from the clamping groove 12 and retracted into the through hole 22 under the action of the spring 51. The limiting rod 11 is rotated to make the limiting rod 11 break away from the notch 21, and the balancing weight 2 is completely exposed. The hook of a hoisting machine such as a crane is hung on the hook 25, and the counterweight block 2 is hoisted from the counterweight table 1. The number of clump weights 2 to be removed from the weight table 1 is determined according to the specific regulations of the vehicle transport weight in the road transport regulations. The removed weight block 2 is transported separately by using a vehicle.

The embodiments of the present invention are preferred embodiments of the present application, and the scope of protection of the present application is not limited by the 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.
