Description

TECHNICAL FIELD

[0001] The utility model relates to horizontal directional drilling rig technical field especially relates to a horizontal directional drilling rig drill rod grabbing device. BACKGROUND

[0002] Horizontal directional drilling technology is the new construction technology that combines the directional drilling technology of petroleum industry and the traditional pipeline construction, and is widely applied in the pipeline laying engineering field of water supply, gas, electricity, telecommunication, natural gas, petroleum and the like with the characteristics of fast construction speed, high precision and low cost.

[0003] In the construction process of the horizontal directional drilling rig, the continuous drilling or back dragging work needs to be realized by increasing or reducing the drill rod. In the prior art, one or two people need to manually carry or use the mechanical gripper on the crane to assist the drill rod loading and unloading in combination with the overturning clamping mechanism of the drilling rig.

[0004] The mechanical gripper includes a simple lifting appliance using hydraulic drive clamping. Generally, the drill rod grabbing in the construction process is basically the simple lifting appliance made by the user, such as a simple hook for hooking the two ends of the drill rod and a simple connecting rod gripper. The worker needs to frequently bend down to position the lifting appliance in the grabbing process, which is labor-intensive and slow. Moreover, the mechanical gripper and the overturning clamping mechanism are prone to damage, bump and scratch the drill rod in the grabbing and clamping processes. Therefore, the market provides a horizontal directional drilling rig drill rod grabbing device. When the device is used, the drill rod taking and placing mechanism can stably take the drill rod by attracting the drill rod with the attracting member. After the drill rod taking and placing mechanism takes the drill rod, the mechanical arm drives the drill rod taking and placing mechanism to move to the required working position. When the drill rod taking and placing mechanism needs to place the drill rod, the attracting member releases the attraction to the drill rod. The device can avoid the complex process of grabbing the drill rod in the previous drill rod carrying work and avoid the problem that the drill rod is easily damaged when the mechanical hand grabs the drill rod in the previous drill rod transfer. The device can also faster realize the drill rod carrying and unloading work.

[0005] However, the above-mentioned disclosed technology still has some disadvantages in practical application. First, the drill rod is attracted by the magnetic attraction method. Once a power failure occurs, there is no safety measure under the drill rod, and the drill rod will directly fall and be damaged. Second, the length of the drill rod extending from the mechanical arm clamping part at both ends cannot be adjusted after clamping. All the adjustment positions need to be completed by the mechanical arm, which is not flexible. In summary, it is necessary to improve and optimize the structure of the horizontal directional drilling rig drill rod grabbing device. UTILITY MODEL CONTENTS
