Description

Technical Field

[0001] The invention relates to a trolley, in particular to a two-way construction drilling, anchoring, grouting, netting and spraying frame integrated trolley. Background Art

[0002] Drilling and blasting is a commonly used method for underground engineering excavation. It forms underground space through drilling, charging, blasting, slagging and other processes. For underground chambers of different shapes and sizes, the drilling and blasting method can be adapted by adjusting the drilling and blasting parameters.

[0003] However, the drilling and blasting method requires a series of processes such as drilling, charging, blasting, and slag removal, and each process takes a certain amount of time, so the overall construction progress is relatively slow. In addition, the construction mostly relies on manual operation and the degree of automation is low, which not only increases the construction cost, but also seriously reduces the construction efficiency. Summary of the invention

[0006] The grouting wet spraying arm includes a second arm frame, one end of which is equipped with a sliding spraying mechanism, the sliding spraying mechanism is connected to the wet spraying material feeding system through a feeding pipeline, the other end of the second arm frame is slidably matched with one end of the first arm frame and is driven to be extended and retracted by a telescopic cylinder, the other end of the first arm frame is hinged to the first support seat and is driven to be lifted or lowered by the first pitch cylinder; the first support seat is fixed on the first turntable, and the first turntable is rotatably connected to the base and is driven to rotate by a motor.

[0007] The arch mounting arm includes a fourth arm, one end of which is equipped with an arch mounting manipulator, the other end of the fourth arm slidingly cooperates with one end of the third arm and is driven to extend and retract through a second telescopic cylinder; the other end of the third arm is hinged to the second support seat and is driven to be lifted or lowered through a second pitch cylinder; the second support seat is fixed on the second turntable, and the second turntable is rotatably connected to the base and driven to rotate by a motor.

[0008] The main rock drilling arm includes a third turntable, which is rotatably mounted on the base and driven to rotate by a motor; a third support seat is fixed to the upper end of the third turntable; a fifth arm is hinged on the third support seat, and the fifth arm is driven to swing up and down by a third pitch cylinder; a sixth arm is slidably arranged on the top of the fifth arm, and the sixth arm is driven to move left and right by a third telescopic cylinder; the main drilling rig system is installed on the sixth arm.

[0009] The anchor mounting arm includes a first swivel seat, which can be rotatably mounted on the base and driven to rotate by a motor; a fourth support seat is fixed on the swivel seat, an eighth arm is hinged on the fourth support seat, and the eighth arm is driven to be lifted or lowered by a fourth pitch cylinder; a fourth telescopic cylinder is installed on the top of the eighth arm, and the fourth telescopic cylinder drives the seventh arm to be telescoped; a second swivel seat is installed on the other end of the seventh arm, and the second swivel seat drives the anchor-injection integrated system to rotate.

[0030] The second arm 512 is slidably matched with one end of the first arm 511 and driven to slide by the telescopic cylinder 514, so that the second arm 512 is extended or retracted relative to the first arm 511. The other end of the first arm 511 is hinged to the first support seat and is driven by the first pitch cylinder 513 to be raised or lowered. The first support seat is fixed on the first turntable, and the first turntable is rotatably connected to the base 400 and driven to rotate by the motor, so that the grouting wet spray arm 510 can swing left and right.

[0031] The wet spraying function module includes a feed pipeline and a sliding spraying mechanism. The feed pipeline is integrated in the first arm 511 and the second arm 512, and is connected to the wet spraying material receiving and feeding system 600 through a pipeline to form a feed system.

[0032] The sliding spraying mechanism is installed at the end of the second boom 512. The sliding spraying mechanism can be driven by a motor to rotate 360 ​​degrees relative to the second boom 512, thereby meeting the requirements of large-scale cave excavation and spraying construction.

[0033] The sliding shotcrete mechanism is a widely used mechanical component on the spray-mixing trolley. It is generally not made into a separate product and does not have a specific model. The designs of mainstream equipment manufacturers are similar, so no special explanation is given here.

[0034] Preferably, a first platform 515 is fixedly installed on one side of the second boom 512, and the first platform 515 is used by workers to perform fine operations such as spraying concrete.

[0035] like Figure 4 As shown, the arch mounting arm 520 includes a third arm 521 , a fourth arm 522 , a slider 523 , a second telescopic cylinder 524 , a second pitch cylinder 525 , a second support seat 526 , a second turntable 527 and an arch mounting manipulator 528 .

[0038] Since the arch structure is arc-shaped, the arch installation robot 528 is adapted to the arch structure, so the arch installation arm 520 can be directly used to lift and move.

[0039] The arch installation robot 528 is a widely used mechanical component on the arch trolley. It is usually not made into a separate product and does not have a specific model. The designs of mainstream equipment manufacturers are similar, so no special explanation is given here.

[0044] The first swivel seat 547 is rotatably mounted on the base 400 and driven to rotate by a motor. A fourth support seat 546 is fixed to the first swivel seat 547, and an eighth boom 542 is hinged to the fourth support seat 546. The eighth boom 542 is driven to be raised or lowered by a fourth pitch cylinder 544.

The structure of the auxiliary rock drilling arm 550 is basically the same as that of the main rock drilling arm 530.

[0049] The auxiliary drilling system 558 can rotate 360 ​​degrees and can meet the needs of 15m-level extra-large section full-section drilling construction; the auxiliary drilling system 558 includes hydraulic system pipelines and drill rod propulsion beams.
