Description

Technical Field

[0001] This utility model relates to the field of drilling rigs, specifically to a drill rod clamping rocker arm lifting assembly. Background Technology

[0002] The supply and removal of drill rods in existing trenchless drilling rigs are mostly achieved by a rotating manipulator on the side of the drill frame, such as the solution disclosed in Chinese Utility Model Patent Application No. 202221862728.1.

[0003] When drill pipe needs to be supplied, the robotic arm grips the drill pipe from its lower limit position, rotates and flips upward relative to the drill frame until it reaches its upper limit position above the drill frame. When drill pipe needs to be unloaded, the robotic arm grips the drill pipe and flips it downward from its upper limit position to its lower limit position.

[0004] While this method can achieve the vertical supply of drill pipe, the outward flipping action of the robotic arm requires the side area of ​​the drill frame to be open to avoid interfering with the vertical flipping action of the robotic arm.

[0005] In actual construction sites, there may be piles of soil, walls, construction workers or other construction equipment on the side of the drilling rig, which limits space and causes inconvenience. Utility Model Content

[0006] The purpose of this utility model is:

Compared with the existing outward flipping vertical movement method, it eliminates the requirement to clear the working area on the side of the drill frame, and is suitable for actual construction sites with limited space.

[0008] To achieve the above objectives, the present invention provides the following technical solution:

[0009] A drill pipe clamping rocker arm lifting assembly includes a base beam, a rocker arm lifting mechanism, and a robotic arm clamping mechanism. Both the rocker arm lifting mechanism and the robotic arm clamping mechanism are located on the base beam. The rocker arm lifting mechanism includes a rocker arm, a connecting rod, a rotating frame, and a lifting cylinder. The rocker arm is hinged to the base beam, and a lifting roller is provided at the top of the rocker arm. The connecting rod is hinged to the bottom of the rocker arm and the rotating frame, respectively. The rotating frame is located between two rocker arms. The piston rod of the lifting cylinder is hinged to the lower part of one of the rocker arms. The robotic arm clamping mechanism includes a movable seat and a gripper. The movable seat is movably mounted on the base beam, and the gripper is movably mounted at one end of the movable seat. The lifting roller corresponds to the vertical position of the gripper.

[0010] Furthermore, the rocker arm is hinged to the base beam via an upper shaft seat, and the two rocker arms are arranged opposite each other.

[0011] Furthermore, the connecting rod is located below the base beam, and both ends of the rotating frame are hinged to the two connecting rods respectively; the rotating frame is hinged to the base beam through the lower bearing seat.

[0012] Furthermore, the lifting cylinder is located below the base beam, the cylinder body of the lifting cylinder is hinged to the base beam through the cylinder seat, and the hinge point between the piston rod of the lifting cylinder and the rocker arm is located between the upper shaft seat and the connecting rod.

[0013] Furthermore, the robotic gripper mechanism also includes a motor, which is located on a fixed seat of the base beam, and the movable seat is movably mounted on the fixed seat; a transmission rod is provided on the rotating shaft of the motor.

[0014] Furthermore, a gear is provided on the transmission rod, and a rack is provided at the bottom of the movable seat, the rack meshing with the gear.

[0029] The rocker arm lifting mechanism 2 includes a rocker arm 21, a connecting rod 24, a rotating frame 25, and a lifting cylinder 27. The rocker arm 21 is hinged to the base beam 1, and a lifting roller 23 is provided at the top of the rocker arm 21. The rocker arm 21 can rotate up and down relative to the base beam 1, thereby realizing the lifting and lowering of the drill pipe. The lifting roller 23 is used for positioning and supporting the drill pipe.

[0030] The connecting rod 24 is hinged to the bottom of the rocker arm 21 and the rotating frame 25 respectively. The rotating frame 25 is located between the two rocker arms 21. The piston rod of the lifting cylinder 27 is hinged to the lower part of one of the rocker arms 21. The connecting rod 24 is used for transmission. The lifting cylinder 27 is used to drive the rocker arm 21 to move.

[0031] The robotic gripper 3 includes a movable base 35 and a gripper 37. The movable base 35 is movably mounted on the base beam 1, and the gripper 37 is movably mounted at one end of the movable base 35. The lifting roller 23 corresponds to the vertical position of the gripper 37. The gripper 37 is used to clamp or release the drill rod, and the lifting roller 23 is used to remove the drill rod from or put it into the gripper 37.

[0032] The rocker arm 21 is hinged to the base beam 1 via the upper shaft seat 22. The two rocker arms 21 are arranged opposite each other. The rocker arms 21 can rotate up and down inside the base beam 1 and will not rotate outward.

[0033] The connecting rod 24 is located below the base beam 1, and the two ends of the rotating frame 25 are respectively hinged to the two connecting rods 24; the rotating frame 25 is hinged to the base beam 1 through the lower bearing 26, and the rotating frame 25 is used for transmission.

[0034] The lifting cylinder 27 is located below the base beam 1. The cylinder body of the lifting cylinder 27 is hinged to the base beam 1 through the cylinder seat 28. The hinge point between the piston rod of the lifting cylinder 27 and the rocker arm 21 is located between the upper shaft seat 22 and the connecting rod 24. The lifting cylinder 27 can be selected as a single piston rod linear cylinder.

[0035] The robotic gripper mechanism 3 also includes a motor 31, which is located on a fixed seat of the base beam 1. A movable seat 35 is movably mounted on the fixed seat; the movable seat 35 can reciprocate linearly relative to the fixed seat.

[0036] A transmission rod 32 is mounted on the shaft of the motor 31; the motor 31 is used to drive the transmission rod 32 to rotate.

[0037] A gear 33 is provided on the transmission rod 32, and a rack 34 is provided at the bottom of the movable seat 35. The rack 34 meshes with the gear 33, and the gear 33 is used to drive the movable seat 35 with the rack 34 to reciprocate.

[0040] The working principle of this utility model is as follows:

[0041] When the drill rod needs to be supplied or lifted, the gripper 37 of the robotic arm clamping mechanism 3 clamps the drill rod located in the clamping groove 351. The motor 31 drives the transmission rod 32 to rotate, and the gear 33 rotates together. Under the meshing action of the rack 34, the moving seat 35 moves linearly relative to the fixed seat until the clamping groove 351 corresponds to the upper and lower positions of the lifting roller 23.

[0042] Subsequently, the piston rod of the clamping cylinder 36 retracts, driving the clamp 37 to release the drill rod; the piston rod of the lifting cylinder 27 of the rocker arm lifting mechanism 2 extends, driving the rocker arm 21 to rotate relative to the base beam 1, causing one end of the lifting roller 23 to rotate upward.

[0043] Under the linkage of connecting rod 24, the rotating frame 25 rotates clockwise relative to the base beam 1. This, in turn, pulls the bottom of another rocker arm 21 via another connecting rod 24, causing the other rocker arm 21 to flip upwards synchronously. This, in turn, causes the lifting rollers 23 on both rocker arms 21 to lift the drill rod located in the clamping groove 351 and raise it vertically upwards, achieving the desired effect. Figure 1 The drill pipe can be lifted and supplied as shown in the diagram.

[0044] When it is necessary to remove the drill pipe, the action is the reverse of the above action, and will not be repeated.

[0045] The above embodiments are used to further illustrate the present invention, but do not limit the present invention to these specific embodiments. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be understood as being within the protection scope of the present invention.
