Description

Technical Field

[0001] The utility model relates to the technical field of drilling equipment, in particular to a locking device for supporting a drill tower. Background Art

[0002] Hydraulic tower erection is a widely used method for erecting a drill tower. After the drill tower is erected hydraulically, it cannot be fixed only by a hydraulic cylinder for a long time. A device is needed to assist in supporting and locking the drill tower so that the drill tower can stand firmly for a long time. Since the drill tower is large in mass and height, the locking device providing support at the bottom should be made of materials with a relatively large mass to lower its center of gravity. However, materials with a large mass are often inconvenient to move and difficult to install. Content of the Utility Model

[0003] The purpose of this application is to provide a locking device for supporting a drill tower, aiming to solve the problems in the above-mentioned prior art.

[0004] This application provides a locking device for supporting a drill tower, including a lower support block and a support plate. A limiting rod is slidably connected to the lower support block; two vertical support blocks are fixedly connected to both sides of the lower support block respectively. Two first connection blocks are fixedly connected to the side of the vertical support block far from the lower support block. The first connection block is threadedly connected with a first screw rod, and the first screw rod is rotatably connected in a second connection block; a second screw rod is threadedly connected to the support plate; two inclined support blocks are fixedly connected to both sides of the support plate respectively. Two of the second connection blocks are fixedly connected to the side of each inclined support block far from the support plate; a universal pulley is connected to the center of the bottom of the lower support block, the support plate, the vertical support block and the inclined support block.

[0005] Further, a slideway with a circular cross-section is formed in the lower support block, and the limiting rod is slidably connected in the slideway. The diameter of the slideway matches the diameter of the limiting rod.

[0006] Further, the right side of the vertical support block and the right side of the lower support block are in the same plane, and the left side of the first connection block and the left side of the lower support block are in the same plane.

[0007] Further, a first screw hole penetrating through the left and right sides of the first connection block is formed in the first connection block. The diameter of the first screw hole matches the diameter of the first screw rod.

[0008] Further, a first screw head is fixedly connected to the end of the first screw rod far from the first connection block. The length of the first screw rod is equal to the sum of the lengths of the corresponding first connection block and second connection block and the length of the distance between the first connection block and the second connection block.

[0009] Furthermore, a second screw hole is also formed in the lower support block, and the diameter of the second screw hole matches the diameter of the second screw rod.
