Description

Technical Field

[0001] The utility model relates to the technical field of anchor rod trolleys, in particular to an anchor rod trolley grab arm adjustment structure. Background Art

[0002] An anchor trolley is a self-moving device that drills anchor holes in the roof or side of underground tunnels and completes part or all of the anchor installation process. With the popularization and development of anchor support operations in underground projects such as mine shafts and tunnels, major foreign mining equipment companies have successively launched trolley-type anchor drilling and assembling vehicles with full functions and high degree of automation, truly realizing the high degree of mechanization and intelligence of anchor support construction, thereby reducing the burden on workers and improving work efficiency and construction quality.

[0003] A Chinese patent with publication number CN217421231 U discloses an anchor rod library with adjustable anchor rod length for an anchor rod trolley, comprising a main shaft, an anchor rod mounting plate, a rotary drive device, a propulsion beam, a fixed fixture, a sliding fixture and a telescopic oil cylinder. The main shaft comprises a coaxial fixed shaft and a telescopic shaft, which are installed as a whole through a connecting structure. The telescopic shaft can slide in the axial direction relative to the fixed shaft and is relatively fixed in the radial and rotational directions. The fixed shaft is fixed to one end of the propulsion beam by a fixed fixture, and the fixed shaft can rotate relative to the fixed fixture. The telescopic shaft is located at the other end of the propulsion beam and is installed on the slide rail of the propulsion beam by a sliding fixture. A slider is installed at the connection between the sliding fixture and the slide rail. The slider cooperates with the slide rail to push the telescopic shaft to slide along the axial direction. The rotary drive device is fixed to the propulsion beam to drive the fixed shaft and the telescopic shaft to rotate. The utility model can adapt to many different types of anchor rods.

[0004] As mentioned above, the patent provides an anchor rod library with adjustable anchor rod length for an anchor rod trolley, which can adapt to a variety of different types of anchor rods. However, when the accuracy requirements are relatively high, it is difficult to adjust the anchor rods by only adjusting the construction point of the anchor rod support operation by bending the grab arm, and thus the work efficiency needs to be improved.

[0007] Preferably: the number of the fixed baffles is set to two, and the two fixed baffles are respectively fixedly connected to the two sides of the top of the anchor vehicle body; the two ends of the reciprocating screw rod are respectively rotatably connected to the surfaces of the two fixed baffles; the two sides of the limit bracket are fixedly connected to the surfaces of the two fixed baffles.

[0008] Preferably: a motor seat is fixedly connected to one side of the anchor vehicle body; a motor is fixedly connected to the top of the motor seat; and an output shaft of the motor is fixedly connected to one end of the reciprocating screw rod through a coupling.

[0009] Preferably, a T-shaped slider is fixedly connected to the bottom of the movable rotating frame; and a sliding rail adapted to the T-shaped slider is provided on one side of the top of the anchor vehicle body.

[0010] Preferably, the bottom of the anchor truck body is rotatably connected to a support shaft; the number of the support shafts is set to two, and both ends of the two support shafts are fixedly connected to moving wheels.

[0011] The beneficial effects of adopting the above technical solution are:

[0012] By setting up an adjustment component, when working, the reciprocating screw drives the L-shaped moving base to start moving, and the sliding base and the moving turntable are fixed on the L-shaped moving base, so that after the L-shaped moving base moves, it drives the sliding base and the moving turntable to move left and right, thereby realizing the horizontal adjustment function. In addition, a rotating base is fixed on the top of the sliding base, and the rotating base is connected to the hydraulic rod through the rotation of the rotating frame. The operation of the hydraulic rod drives the rotating base to rotate, and then cooperates with the electric telescopic rod to drive the claw disk to extend and retract, thereby realizing the vertical adjustment function, which is convenient for adjusting the anchor rod installed in the claw disk, thereby improving the work efficiency.
