[0030] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but cannot be understood as limiting the present invention.

[0031] like Figure 1 and Figure 2 As shown, an embodiment of the utility model discloses a limiting device 40 for a hydraulic anchor drilling vehicle, the hydraulic anchor drilling vehicle comprises a small arm frame 11 and a slide rail 12, the small arm frame 11 has a slideway 111, the slide rail 12 can be slidably matched with the slideway 111, the small arm frame 11 comprises a rear end plate 15 arranged on the rear side of the slide rail 12; the limiting device 40 comprises a limiting frame 4, the limiting frame 4 is connected to the small arm frame 11, the limiting frame 4 has a limiting portion arranged toward the slide rail 12, the limiting portion and the rear end plate 15 are arranged at intervals, so that when the slide rail 12 stops at the limiting portion, a safety gap is formed between the slide rail 12 and the rear end plate 15.

[0032] The hydraulic anchor drill vehicle limiting device 40 of the embodiment of the utility model, during the drilling operation, if the operator places his feet, hands, etc. on the rear end plate 15, when the secondary oil cylinder 14 of the hydraulic anchor drill vehicle drives the slide rail 12 to retract, the slide rail 12 stops at the limiting portion, and a safety gap can be formed between the slide rail 12 and the rear end plate 15. The operator's feet, hands, etc. are located in the safety gap, thereby reducing the risk of the operator being squeezed and injured, reducing safety hazards.

[0033] like Figure 1 and Figure 2 As shown, the slide rail 12 is in the shape of an elongated strip, and the slide rail 12 can be slidably matched with the slideway 111, and the slide seat 13 can be slidably matched with the slide rail 12. A rotary motor 131 is provided on the slide seat 13, and the drill rod 30 is connected to the output end of the rotary motor 131; the first-level oil cylinder (not shown in the figure) can control the slide seat 13 to slide relative to the slide rail 12, and the second-level oil cylinder 14 can control the slide rail 12 to slide relative to the small arm frame 11, thereby pushing the drill rod 30 forward to realize the drilling operation.

[0034] It is understandable that if Figure 1 As shown, the extension direction of the slide 111 is the front-to-back direction. During the drilling operation, the slide rail 12 moves forward to push the drill rod 30 forward. When the small arm 11 is extended in the up-down direction, the rear end of the slide 111 is the bottom end of the slide 111.

[0035] In some embodiments, Figure 2 As shown, the limiting frame 4 includes a limiting plate 41 and a connecting plate 42, the connecting plate 42 is connected to the rear end plate 15, the limiting plate 41 is connected to the connecting plate 42, the side of the limiting plate 41 facing the slide rail 12 is a limiting surface 411, and the limiting surface 411 forms a limiting portion.

[0036] By providing the connecting plate 42, the installation position on the rear end plate 15 can be used to connect the connecting plate 42 with the rear end plate 15, thereby improving the convenience of installing the limit plate 41. In addition, when the slide rail 12 retracts under the action of the secondary oil cylinder 14, it stops at the limit surface 411, and the slide rail 12 and the limit frame 4 are in surface contact, which can improve the stability of the slide rail 12 when it retracts.

[0037] Optionally, the limiting plate 41 and the connecting plate 42 are fixed to each other by welding or integrally forming.

[0038] Therefore, the connection between the limiting plate 41 and the connecting plate 42 is more stable.

[0039] In some embodiments, the connecting plate 42 is detachably connected to the rear end plate 15 .

[0040] By detachably connecting the connecting plate 42 to the rear end plate 15 , when the limiting plate 41 is damaged during long-term use, it can be replaced, which makes the operation more convenient.

[0041] In some embodiments, the connecting plate 42 is connected to the rear end plate 15 via a bolt assembly 43 .

[0042] The connecting plate 42 and the rear end plate 15 are connected by a bolt assembly 43 , which has low cost and high convenience in operation.

[0043] Alternatively, if Figure 2 As shown, there are four bolt assemblies 43 , and the four bolt assemblies 43 are distributed in a quadrilateral.

[0044] Therefore, it is possible to prevent the connection between the limiting frame 4 and the rear end plate 15 from being loosened when impacted by the slide rail 12 , thereby improving the stability of the connection between the limiting frame 4 and the rear end plate 15 .

[0045] In some embodiments, the connecting plate 42 and the limiting plate 41 are perpendicular to each other, and the limiting plate 41 and the rear end plate 15 are perpendicular to each other.

[0046] Through the above arrangement, the connecting plate 42 can fit the rear end plate 15, and the connection between the connecting plate 42 and the rear end plate 15 is more convenient; at the same time, the plate surface of the limit plate 41 extends from the back to the front, so that a safety gap can be formed on the side of the opening of the limit plate 41 facing the slide 111 for the operator to step on.

[0047] As an example, Figure 2 As shown, the slideway 111 has a bottom wall arranged opposite to its opening, the limiting plate 41 is arranged in contact with the bottom wall of the slideway 111, and the connecting plate 42 is in contact with the rear end plate 15, so that the limiting frame 4 is "L" shaped.

[0048] In some embodiments, the limiting frame 4 further includes a rib plate 44 , which is disposed between the connecting plate 42 and the limiting plate 41 .

[0049] The rib plate 44 can play a supporting and reinforcing role, thereby enhancing the strength of the limiting frame 4 .

[0050] As an example, Figure 2 As shown, the rib plate 44 is in a triangular plate shape and is welded and fixed to the connecting plate 42 and the limiting plate 41 .

[0051] In some embodiments, Figure 3 As shown, the limiting frame 4 also includes an extension plate 45, which is connected to the limiting plate 41, and the extension plate 45 is perpendicular to the limiting plate 41. The side of the extension plate 45 facing the limiting plate 41 is an extension surface 451, and the extension surface 451 forms a limiting portion.

[0052] By providing the extension plate 45 , the area of ​​the limiting portion can be increased, thereby increasing the contact area between the slide rail 12 and the limiting frame 4 , thereby improving the stability of the slide rail 12 when it stops at the limiting frame 4 .

[0053] Optionally, a rib plate 44 is also provided between the extension plate 45 and the connection plate 42 .

[0054] Thereby, the strength of the limiting frame 4 can be further increased.

[0055] In some embodiments, the distance between the limiting surface 411 and the rear end plate 15 is 60 mm to 150 mm.

[0056] By reasonably setting the distance between the limit surface 411 and the rear end plate 15 , the safety gap formed when the slide rail 12 stops at the limit frame 4 is sufficient to ensure the safety of the operator's feet, and at the same time, the impact on the travel of the slide rail 12 can be reduced.

[0057] Optionally, the distance between the limiting surface 411 and the rear end plate 15 is 80 mm, 100 mm, 120 mm or 140 mm.

[0058] In some embodiments, Figure 4 As shown, an infrared sensor for detecting the position of the slide rail 12 is provided between the limiting frame 4 and the slide rail 12 .

[0059] By providing an infrared sensor, a mechanical and electronic dual limit function can be formed to prevent the operator's feet, hands and other parts from being squeezed when the slide rail 12 retracts, thereby further improving the operator's safety.

[0060] In some embodiments, the infrared sensor includes a transmitting end 51 and a receiving end 52 , the transmitting end 51 is used to transmit a target signal to the receiving end 52 , one of the transmitting end 51 and the receiving end 52 is connected to the limit frame 4 , and the other is connected to the slide rail 12 .

[0061] Through the above settings, when the hands, feet or other parts of the operator are between the slide rail 12 and the limit surface 411, the infrared signal is blocked, and the receiving end 52 cannot receive the signal. The slide rail 12 can be controlled to stop sliding, achieving a locking effect, thereby preventing the operator from being squeezed and injured and improving work safety.

[0062] Optionally, the transmitting end 51 is connected to the end surface of the slide rail 12 facing the limiting frame 4 , and the receiving end 52 is connected to the limiting surface 411 .

[0063] Although the embodiments of the present invention have been shown and described above, it is to be understood that the above embodiments are illustrative and cannot be construed as limitations on the present invention. Changes, modifications, substitutions and variations of the above embodiments by those of ordinary skill in the art are all within the scope of protection of the present invention.
