[0034] See attached Figure 1 The embodiment of the present application provides a boom adjustment device, including a first sliding track 1, a first sliding trolley 12, a pitch-slewing mechanism, a second sliding track 2, a second sliding trolley 5, a slide 7, a slewing mechanism, and a grab arm 3. The first sliding track 1 is fixedly mounted on the frame of the construction trolley; the first sliding trolley 12 reciprocates along the first sliding track 1 under the drive of the first power box 11, and the first sliding trolley 12 is provided with a pitch-slewing mechanism, the slide 7 is connected between the pitch-slewing mechanism and the second sliding track 2, the second sliding trolley 5 reciprocates along the second sliding track 2 under the drive of the second power box, the second sliding trolley 5 is provided with a slewing mechanism, and the grab arm 3 is installed on the slewing mechanism.
[0035] In the above description, the pitch-slewing mechanism includes a first slewing reducer 10 and a pitch cylinder 6 , and the slewing mechanism includes a second slewing reducer 4 .
[0036] Specifically:
[0037] See also Figure 1 As shown, the first sliding rail 1 is fixed to the stand by bolts, the first sliding trolley 12 is installed on the first sliding rail 1 by rollers, and the first power box 11 is fixed to the first sliding trolley 12 by bolts. It can move back and forth on the first sliding rail 1 with the first sliding trolley 12 and provide power for the first sliding trolley 12 to move back and forth, ensuring that the first sliding trolley 12 slides back and forth on the first sliding rail 1.
[0038] The first rotary reducer 10 is fixed to the first sliding trolley 12 by bolts, and the first rotary support seat 8 is fixed to the first rotary reducer 10 by bolts to adjust the operation, and the first rotary reducer 10 provides rotational power for the rotation of the first rotary support seat 8. The slide 7 is hinged on the first rotary support seat 8 by a pin shaft, and the pitch cylinder 6 is hinged on the slide 7 and the first rotary support seat 8 by a pin shaft, mainly adjusting the horizontal angle of the second sliding track 2. The second sliding track 2 is slidably mounted on the slide 7, and a third power box 9 is bolted on the second sliding track 2. The third power box 9 provides power for the second sliding track 2 to slide on the slide 7. It can be imagined that the slide 7 can implement a lifting effect on the second sliding track 2, and at the same time, the horizontal angle can be changed under the telescopic action of the pitch cylinder 6, driving the change of the horizontal angle of the second sliding track 2, and based on the relative displacement between the slide 7 and the second sliding track 2, the displacement compensation of the sliding trolley is realized.
[0039] The second sliding track 2 is mounted on the slide 7 through rollers and can slide forward and backward. The second sliding trolley 5 is mounted on the second sliding track 2 through rollers and can slide forward and backward on the second sliding track 2. A second power box is mounted on the second sliding trolley, and the second power box mainly provides power for the second sliding trolley 5 to slide forward and backward on the second sliding track 2. The second rotary reducer 4 is fixed to the second sliding trolley 5 by bolts, and a second rotary support seat is mounted on the second rotary reducer 4. The grab arm 3 is mounted on the second rotary support seat through a pin shaft, and the grab arm can be rotated 360° by the second rotary reducer 4. The second rotary support seat is also hinged with an angle adjustment cylinder through a pin shaft. The end of the angle adjustment cylinder away from the second rotary support seat is movably hinged with the grab arm 3 through a pin shaft. The angle between the grab arm 3 and the second rotary support seat can be adjusted through the angle adjustment cylinder to change the grabbing angle of the grab arm 3.
[0040] Based on the above content, it can be known that the embodiment of the present application provides an arm adjustment device, and its specific working process is:
[0041] like Figure 2 As shown in the figure, when the arch frame in front of the corresponding platform is being grabbed, the first sliding trolley 12 slides to the front of the first sliding track 1 under the action of the first power box 11, and the pitch cylinder 6 is extended to adjust the slide 7 to an angle that satisfies the arch frame grabbing. The second sliding track 2 is installed on the slide 7 through rollers, so that each structure above the slide 7 will tilt at a certain angle with the slide 7. The second sliding track 2 can slide into a Figure 2 The second sliding trolley 5 can slide on the second sliding track 2 under the action of the second power box, and slide to the position shown in FIG. Figure 2 The grab arm 3 as a whole can rotate 360 degrees under the action of the second rotary reducer 4. When grabbing the arch, the first rotary support seat 8 swings left and right under the action of the first rotary reducer 10 according to different positions to meet the requirements of arch grabbing.
[0042] like Figure 3 As shown, when the arch frame behind the corresponding platform is grabbed, it is similar to grabbing the arch frame in front. The first sliding trolley 12 slides to the rear of the first sliding track 1 under the action of the first power box 11, and the pitch cylinder 6 is extended to adjust the slide 7 to an angle that meets the arch frame grabbing. The second sliding track 2 is installed on the slide 7 through rollers, so all structures above the slide 7 will tilt at a certain angle with the slide 7. The second sliding track 2 can slide into a Figure 3 The second sliding trolley 5 can slide on the second sliding track 2 under the action of the second power box, and slide to the position shown in FIG. Figure 3The position shown. The grab arm 3 as a whole can rotate 360 degrees under the action of the second rotary reducer 4. When grabbing the arch frame, the first rotary support seat 8 swings left and right under the action of the first rotary reducer 10 according to different positions to meet the arch frame grabbing. In this process, due to the use of the second sliding track 2 to replace the traditional large arm form, the arm frame is changed into a slide rail form, and the telescopic arm frame is realized by sliding, which can avoid the influence of the long arm frame being unable to perform front and rear working condition grabbing due to insufficient space in the tunnel.
[0043] Of course, the embodiment of the present application also provides an excavation trolley, including a trolley frame and the above-mentioned arm adjustment device, the frame is installed on the trolley body, and the arm adjustment device is installed on the frame through a first sliding track. It can be imagined that based on the arm adjustment device, the excavation trolley can complete the front and rear grabbing of the arch frame in a tunnel with insufficient internal space, which is more practical.
[0044] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present application should be included in the protection scope of the present application.
