[0037] The specific implementation process of this utility model will be described below through several embodiments.

[0038] Example 1

[0039] See Figures 1 to 5 This embodiment discloses a specific implementation of a four-arm anchor bolt transfer unit.

[0040] See Figures 1 to 5The four-arm anchor bolt transfer unit includes a chassis 1, a hopper assembly 2 disposed at the front end of the chassis 1, a four-arm anchor bolt assembly 3 disposed above the chassis 1, and a track beam lifting assembly 4 disposed on at least one side of the chassis 1; the four-arm anchor bolt assembly 3 includes a side anchor assembly 31 and a top anchor assembly 32, the top anchor assembly 32 being movably disposed on the chassis 1; the track beam lifting assembly 4 includes a horizontal slide rail 41, a horizontal slide box 42, a horizontal hydraulic cylinder 43, and a vertical... The system includes a straight slide rail 44, a vertical slide frame 45, a lifting cylinder 46, and a track beam support groove 47. The horizontal cylinder 43 drives the horizontal slide box 42 to move along the horizontal slide rail 41 with the horizontal slide rail 41 as the fulcrum. The vertical slide rail 44 is fixed to the end of the horizontal slide box 42. The lifting cylinder 46 drives the vertical slide frame 45 to rise and fall along the vertical slide rail 44 with the vertical slide rail 44 as the fulcrum. The track beam support groove is installed on the vertical slide frame.

[0041] Specifically, the chassis 1 has a clearance space 5 on at least one side, the track beam lifting assembly 4 is disposed in the clearance space 5, the vertical slide 45 is provided with a chain cylinder 451, a first guide post 452, a second guide post 453 and a slider 454, and the track beam lifting groove 47 is installed on the slider 454; the track beam lifting groove 47 has two stages of lifting. In the first stage, the lifting cylinder 46 drives the vertical slide 45 to rise and fall along the vertical slide rail 44. In the second stage, the chain cylinder 451 drives the slider 454 to rise and fall along the first guide post 452 and the second guide post 453 with the vertical slide 45 as the fulcrum. The working principle of the track beam lifting assembly 4 is as follows: See Figure 3 The horizontal cylinder 43 drives the horizontal slide box 42 to move to its outermost position, so that the vertical slide 45 is in a position away from the chassis 1. The lifting cylinder 46 drives the vertical slide 45 to its lowest position, and the chain cylinder 451 drives the slider to its lowest position. At this time, the track beam lifting groove 47 is very close to the ground, and the operator can place the track beam 6 in the track beam lifting groove 47. See also Figure 4When the track beam 6 needs to be lifted, the lifting cylinder 46 drives the vertical slide 45 to its highest position, and the chain cylinder 451 drives the slider to its highest position. At this time, the track beam 6 is in its highest position, and the operator can install the track beam 6 on this basis, greatly reducing the labor intensity. When the track beam does not need to be installed, the lifting cylinder 46 drives the vertical slide 45 to a suitable position, the chain cylinder 451 drives the slider to a suitable position, and the horizontal cylinder 43 drives the horizontal slide box 42 to move into the clearance space 5 to avoid affecting the space on both sides of the transfer unit. In a preferred embodiment, track beam storage slots 7 are respectively provided on both sides of the chassis 1, which can store several track beams 6 for use by the track beam lifting assembly 4. A track beam buffer bracket 8 is provided above the track beam lifting assembly 4. The track beam buffer bracket 8 has several slots 81, which can temporarily store several track beams 6. When necessary, the operator can take the track beams 6 from the slots 81.

[0042] See Figure 1 The hopper assembly 2 includes a horizontal bottom 21 and a first ramp 22 and a second ramp 23 connected to both sides of the horizontal bottom 21. Both the first ramp 22 and the second ramp 23 are provided with planetary gears 24. When the hopper assembly 2 receives coal, the coal accumulated in the first ramp 22 and the second ramp 23 can be quickly transported to the horizontal bottom 21 by the planetary gears 24, effectively preventing coal from accumulating in the first ramp 22 and the second ramp 23.

[0043] See Figure 1 The side anchoring assembly 31 includes a first lifting assembly 311, a first rotating assembly 312, a first drill arm 313, a second lifting assembly 314, a second rotating assembly 315, and a second drill arm 316. The first lifting assembly 311, the first rotating assembly 312, and the first drill arm 313 form an anchoring assembly for one side of the roadway. The first lifting assembly 311 drives the first rotating assembly 312 to lift and lower, the first rotating assembly 312 drives the first drill arm 313 to swing, and the first rotating assembly 312 drives the first drill arm 313 to be in a vertical state or to anchor the side. In the rod state, the first lifting assembly 311 drives the first drill arm 313 to drive anchor bolts at different heights in the sidewall; the second lifting assembly 314, the second rotating assembly 315 and the second drill arm 316 form an anchoring assembly for another sidewall of the roadway. The second lifting assembly 314 drives the second rotating assembly 315 to lift and lower, the second rotating assembly 315 drives the second drill arm 316 to swing, the second rotating assembly 315 drives the second drill arm 316 to be in a vertical state or in the state of driving sidewall anchor bolts, and the second lifting assembly 314 drives the second drill arm 316 to drive anchor bolts at different heights in the sidewall.

The first sliding cylinder 321, the second sliding cylinder 322, the second sliding cylinder 323, the second sliding cylinder 324, the third drill arm 325, and the fourth drill arm 325 are respectively located at both ends of the sliding housing 323. 22 synchronously drives the sliding box 323 to move back and forth. Without moving the vehicle, the sliding box 323 moves back and forth synchronously through the first sliding cylinder 321 and the second sliding cylinder 322, thereby enabling the third drill arm 324 and the fourth drill arm 325 to move back and forth, adjusting the position of the anchor bolts on the top of the roadway, and improving the flexibility and adaptability of the transfer unit's anchoring.
