Description

Technical Field

[0001] The utility model relates to the technical field of auxiliary supporting devices under mines, in particular to a telescopic front shovel plate structure on a double-arm drilling vehicle. Background Art

[0002] When the drilling rig continues to work underground, it needs to continue to advance along the tunnel. At the same time, since the anchor drilling device on the drilling rig needs the body of the drilling rig to remain stable during construction, the ground where the drilling rig is located needs to be leveled. Although some drilling rigs are currently equipped with a shovel at the front end of the body, the shovel structure is relatively simple and only has the function of leveling the ground. In addition, the width of the shovel is fixed, and it is easy to interfere with and collide with other equipment in the complex environment of the mine. This is the main problem that needs to be solved at present. Utility Model Content

[0010] Preferably, an inner bottom shovel is provided on the back side of the main shovel plate; a guide groove is also provided between the extension shovel plate and the extension block, and one end of the inner bottom shovel can be inserted into the guide groove and move.

[0011] Beneficial effects of the utility model:

[0012] The utility model designs a retractable front shovel plate structure that can adjust the width, which provides a positioning hole for movably connecting with the vehicle body, thereby realizing that when the shovel plate is needed for leveling work, its width can be increased by stretching the shovel plate, thereby leveling a larger road surface; and during the movement, the shovel plate only needs to be retracted to effectively reduce its width, thereby avoiding the hidden danger of interference and collision with underground equipment; and when it is needed for support, it can be controlled by the posture of the vehicle body at the positioning hole, so that the front side of the shovel plate can be supported on the ground. It has a simple structure, is easy to operate, has a better leveling effect, and can provide a certain front support effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0018] Example:

[0019] Reference Figure 1This embodiment provides a retractable front shovel structure for a double-arm drilling vehicle. The structure comprises a pair of clamping plates 1. A first positioning hole 2 and a second positioning hole 3 are formed in the clamping plates 1. A connecting sleeve 4 is installed at the first positioning hole 2. The clamping plates 1 are mounted on the drilling vehicle via the connecting sleeve 4. A guide block 5 is also provided on the clamping plates 1. A telescopic hydraulic cylinder 6 and an extension block 7 are installed on the guide block 5. One end of the telescopic hydraulic cylinder 6 is mounted on the extension block 7, and the extension block 7 can be moved on the guide block 5 via the telescopic hydraulic cylinder 6. A main shovel plate 8 is provided on the clamping plates 1. An extension shovel plate 9, flush with the main shovel plate 8, is provided on the extension block 7. In this embodiment, the second positioning hole 3 is a stepped structure. A hydraulic push rod is provided on the drilling vehicle, and the movable end of the hydraulic push rod is hingedly mounted at the second positioning hole 3 via a connecting pin, thereby driving the entire shovel plate to rotate.

[0020] The splint 1 includes a triangular plate structure; the first positioning hole 2, the second positioning hole 3 and the guide block 5 are all arranged on the triangular plate; a crane-beak-shaped extension plate 10 is arranged at one corner of the triangular plate; the main shovel plate 8 is arranged at the side edge position where the extension plate 10 is located.

[0021] A third positioning hole 11 is further formed in the triangular plate portion of the clamping plate 1 , and one end of the guide block 5 is clamped in the third positioning hole 11 .

[0022] Several connecting plates 12 are also provided between the clamping plates 1 .

[0023] The guide block 5 is a hollow square tube structure, and the telescopic hydraulic cylinder 6 is installed in the inner cavity of the guide block 5; the extension block 7 is a hollow square tube structure that can be sleeved on the outer peripheral side of the guide block 5; through holes are opened on the guide block 5 and the extension block 7; the movable end and the fixed end of the telescopic hydraulic cylinder 6 are installed at the corresponding through holes through pins.
