Description
Technical Field
[0001] This utility model relates to the field of hydraulic drilling rig technology, specifically to a drill rod gripping device for a hydraulic drilling rig. Background Technology
[0002] Currently, drilling rigs are widely used in drilling and excavation for projects such as metallurgy, coal, building materials, railways, highways, mines, hydropower construction, industrial and civil buildings, and national defense construction.
[0003] Currently available hydraulic drilling rig drill rod gripping devices use gripping clamps to grasp drill rods. However, existing gripping devices can only grip drill rods in one direction. When gripping drill rods in other directions is required, the direction of the gripping device needs to be manually adjusted, which is inconvenient. In addition, the gripping clamp angle of existing drill rod gripping devices is fixed, making it impossible to grip drill rods of different sizes at the same time, resulting in reduced gripping efficiency. Utility Model Content
[0004] The purpose of this utility model is to provide a drill rod gripping device for a hydraulic drilling rig, so as to solve the problem of the single gripping angle of the existing hydraulic drilling rig drill rod device.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] A drill rod gripping device for a hydraulic drilling rig includes a movable arm with a placement groove, a support block, a rotating component, and a moving component. The support block is located inside the placement groove and has a sliding groove. The moving component is located inside the sliding groove. Both the movable arm and the support block have rotating holes of the same size. The rotating component passes through the rotating holes and is rotatably connected to the bottom of the placement groove. The rotating component allows the support block to rotate laterally or longitudinally. The device also includes a gripping component that is slidably connected to the moving component and grips the drill rod.
[0007] Preferably, the rotating component includes a rotating motor and a slide rod. The rotating motor is fixed to the outside of the moving arm by a motor frame. The output end of the rotating motor is fixed to one end of the slide rod by a coupling. The slide rod passes through the rotating hole and is rotatably connected to the bottom of the placement slot.
[0008] Preferably, the moving part includes a screw, which is located inside the sliding groove via a bearing seat. A drive motor is fixed to the outside of the support block via a motor frame. The output end of the drive motor is fixed to one end of the screw via a coupling. The screw is slidably connected to the gripping component. A limit rod is fixed inside the sliding groove. The limit rod slides through the gripping component and is driven by the drive motor and the lead screw of the gripping component. The limit rod limits the gripping component, allowing the gripping component to move left and right.
[0009] Preferably, the gripping component includes a fixed block, which is slidably connected to the screw. A limiting rod slides through the fixed block, and a fixed rod is fixed inside the fixed block. A placement plate is fixed on the fixed rod, and a shrinkage groove is provided on one side of the placement plate. An electric shrinkage plate is fixed inside the shrinkage groove, and gripping clamps are fixed on both the placement plate and the electric shrinkage plate. The electric shrinkage plate enables the gripping clamps to adjust and grip according to the size of the drill rod.
[0010] Preferably, the gripper is made of metal, which is not easily damaged, and the gripper is coated with a dustproof layer to prevent dust from affecting the stability of the gripper in gripping the drill rod.
[0011] Preferably, the inner walls of both the sliding groove and the placement groove are smooth planes, which facilitates the sliding of the fixing block in the sliding groove and the rotation of the support block in the placement groove.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] This solution addresses the issue of the limited gripping angle in traditional hydraulic drilling rig drill rod devices:
[0014] 1. The operator first grasps the drill rod using the gripping component, then moves the gripping component left and right using the moving component, and finally controls the support block to adjust its direction as needed by the rotating component, so that the gripping component can grasp drill rods in different directions, making it convenient to grasp drill rods at different angles and avoiding the inconvenience of a single gripping angle.
[0015] 2. First, the operator rotates the motor to drive the slide bar to rotate, so that the support block can be adjusted in direction as needed. Then, the drive motor drives the lead screw of the gripping component, and the limit rod limits the gripping component, so that the gripping component can move left and right. Then, the electric retraction plate allows the gripping clamp to be adjusted according to the size of the drill rod, so as to avoid the inability to grip drill rods of different sizes at the same time, which helps to improve gripping efficiency.

The support block 3 is located inside the placement groove 2 and has a sliding groove 6. The moving component 5 is located inside the sliding groove 6. Both the movable arm 1 and the support block 3 have rotating holes 7 of the same size. The rotating component 4 passes through the rotating hole 7 and is rotatably connected to the bottom of the placement groove 2. The rotating component 4 allows the support block 3 to rotate laterally or longitudinally. The device also includes a gripping component 8, which is slidably connected to the moving component 5 and grips the drill rod.
[0024] Specifically, this solution addresses the issue of the limited gripping angle of traditional hydraulic drilling rig drill rod devices.
[0025] The operator first grabs the drill rod using the gripping component 8, then moves the gripping component 8 left and right using the moving component 5, and finally controls the support block 3 to adjust its direction as needed using the rotating component 4, so that the gripping component 8 can grab drill rods in different directions, making it easier to grab drill rods at different angles and avoiding the inconvenience of a single gripping angle.
[0026] Further reference Figure 1 - Figure 5 As shown, the rotating component 4 includes a rotating motor 9 and a slide rod 10. The rotating motor 9 is fixed to the outside of the moving arm 1 by a motor frame. The output end of the rotating motor 9 is fixed to one end of the slide rod 10 by a coupling. The slide rod 10 passes through the rotating hole 7 and is rotatably connected to the bottom of the placement groove 2.
[0027] At the same time, refer to Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, the moving part 5 includes a screw 11, which is located inside the sliding groove 6 via a bearing seat. A drive motor 12 is fixed to the outside of the support block 3 via a motor frame. The output end of the drive motor 12 is fixed to one end of the screw 11 via a coupling.
