Description

Technical Field

[0001] The invention relates to the technical field of mining machinery, and in particular to a drill arm clamp integrating drilling and anchoring. Background Art

[0002] Anchor drilling rigs are indispensable equipment in mines, tunnels and underground projects. They are mainly used to install and fix anchors to ensure the stability and safety of the project. In anchor drilling rigs, clamps are usually installed on the drilling frame of the drilling rig, and their opening and closing movements are controlled by hydraulic or mechanical means.

DETAILED DESCRIPTION

[0032] 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 should not be understood as limiting the present invention.

[0033] The following describes the drill-anchor integrated drill arm clamp according to an embodiment of the present invention in conjunction with the accompanying drawings.

[0034] like Figures 1 to 9 As shown, the drill-anchor integrated drill arm clamp of the embodiment of the present invention comprises: a drill frame body and a clamp assembly.

[0035] The drilling frame body comprises a primary frame 1 and a secondary frame 2. The primary frame 1 is slidable along its length direction, and the secondary frame 2 is slidably arranged on the primary frame 1 along its length direction.

[0036] The clamp assembly includes a clamp body 3, a clamp cylinder 4 and two clamp oil pipes 5. The clamp body 3 is connected to the clamp cylinder 4 so that the clamp cylinder 4 drives the clamp body 3 to move. The clamp cylinder 4 is arranged on the upper part of the secondary frame 2 so that the secondary frame 2 slides and drives the clamp cylinder 4 to move. The clamp oil pipe 5 is arranged along the length direction of the primary frame 1, one end of the clamp oil pipe 5 is connected to the bottom of the primary frame 1, and the other end of the clamp oil pipe 5 is connected to the clamp oil cylinder 4. The clamp oil pipe 5 includes an inner tube 501 and an outer tube 502, and the outer tube 502 can be slidably sleeved on the inner tube 501, so that when the position of the clamp oil cylinder 4 on the primary frame 1 changes, the outer tube 502 and the inner tube 501 are driven to slide relative to each other.

[0037] It can be understood that after the primary skeleton 1 is unfolded, during the movement of the secondary skeleton 2 on the primary skeleton 1, the secondary skeleton 2 drives the clamp cylinder 4 and the clamp body 3 to move, and at the same time drives the clamp oil pipe 5 to retract and retract, thereby realizing normal oil supply to the clamp cylinder 4 through the retractable clamp oil pipe 5.

[0038] Therefore, the drill-anchor integrated drill arm clamp of the embodiment of the present invention adopts a clamp oil pipe 5 in the form of a telescopic sleeve structure, which can move synchronously with the secondary skeleton 2, solves the problem that the external oil pipe is easily hung up in the related technology, and improves the reliability and safety of the device operation.

[0039] In some embodiments, Figure 1 and Figure 2 As shown, the primary skeleton 1 includes a first bottom plate 101, a first top plate 102, a support plate 103 and a sliding column 104, one end of the support plate 103 is connected to the first bottom plate 101, the other end of the support plate 103 is slidably connected to the sliding column 104, and the end of the sliding column 104 away from the first bottom plate 101 is connected to the first top plate 102.

[0040] It is understandable that the sliding of the first frame 1 is achieved by sliding the sliding column 104 and driving the first top plate 102 to move. Figure 1 and Figure 2 As shown, a fixing sleeve 105 is provided at one end of the support plate 103 away from the first bottom plate 101 . The fixing sleeve 105 has a sliding hole, and the sliding column 104 can slide through the sliding hole, thereby ensuring the stability of the sliding expansion of the primary frame 1 .

[0041] The secondary frame 2 can slide between the first bottom plate 101 and the first top plate 102, and the secondary frame 2 includes a second bottom plate 201, a second top plate 202 and a support column 203, and both ends of the support column 203 are respectively connected to the second bottom plate 201 and the second top plate 202. For example, a guide column is provided on the secondary frame 2, and the fixing sleeve 105 on the support plate 103 also has a sliding hole for the guide column to slide, so that the secondary frame 2 can slide on the primary frame 1.

[0042] The clamp cylinder 4 is arranged on the second top plate 202. Specifically, Figure 2 and Figure 8 As shown, the clamp cylinder 4 has a cylinder base 401, which is also the cylinder barrel of the clamp cylinder 4. The cylinder base 401 is installed on the surface of the second top plate 202 away from the second bottom plate 201, and the two can be connected by bolts.

[0043] The two ends of the outer tube 502 are connected to the second bottom plate 201 and the second top plate 202 respectively, one end of the inner tube 501 passes through the second bottom plate 201 and is inserted into the outer tube 502, and the other end of the inner tube 501 is connected to the first bottom plate 101. Figures 2 to 4As shown, the inner tube 501 is provided with an inner tube flange 503 at one end connected to the first bottom plate 101, and the first bottom plate 101 is provided with an interface for assembling the inner tube flange 503, and the two can be connected by screws and the connection between the two is sealed. Similarly, the outer tube 502 is provided with an outer tube flange 504 at one end connected to the second bottom plate 201, and the second bottom plate 201 is provided with an interface for assembling the outer tube flange 504, and the two can be connected by screws and the connection between the two is sealed.

[0044] Furthermore, if Figure 4 As shown, a plurality of annular sealing grooves are provided on the inner peripheral wall of the outer tube flange 504 , and a dynamic sealing ring 505 is provided in the sealing groove to ensure the sliding seal between the inner tube 501 and the outer tube 502 .

[0045] In some embodiments, the two clamp oil pipes 5 are respectively a rod chamber clamp oil pipe and a rodless chamber clamp oil pipe. The rod chamber clamp oil pipe is connected to the rod chamber of the clamp oil cylinder 4 , and the rodless chamber clamp oil pipe is connected to the rodless chamber of the clamp oil cylinder 4 .

[0046] Alternatively, if Figure 2 and Figure 5 As shown, a first rod cavity flow channel 1011 and a first rodless cavity flow channel 1012 are provided on the first bottom plate 101 , the inner tube 501 of the rod cavity clamp oil pipe is connected to the first rod cavity flow channel 1011 , and the inner tube 501 of the rodless cavity clamp oil pipe is connected to the first rodless cavity flow channel 1012 .

[0047] like Figure 2 and Figure 6 As shown, the second top plate 202 is provided with a second rod cavity flow channel 2021 and a second rodless cavity flow channel 2022, the outer tube 502 of the rod cavity clamp oil pipe is communicated with the second rod cavity flow channel 2021, and the outer tube 502 of the rodless cavity clamp oil pipe is communicated with the second rodless cavity flow channel 2022. It should be noted that the connection between the outer tube 502 and the second top plate 202 is sealed. For example, a sealing groove is also provided in the interface for the outer tube 502 on the second top plate 202, and a static sealing ring is installed in the groove.

[0048] like Figure 2 and Figure 7 As shown, a third rod cavity flow channel 4011 connected to the rod cavity of the clamp cylinder 4 and a third rodless cavity flow channel 4012 connected to the rodless cavity of the clamp cylinder 4 are provided on the cylinder base 401. The cylinder base 401 is pressed and sealed with the second top plate 202, the third rod cavity flow channel 4011 is connected to the second rod cavity flow channel 2021, and the third rodless cavity flow channel 4012 is connected to the second rodless cavity flow channel 2022.

[0049] Thus, the first rod cavity flow channel 1011 on the first bottom plate 101, the rod cavity clamp oil pipe, the second rod cavity flow channel 2021 on the second top plate 202, and the third rod cavity flow channel 4011 on the cylinder base 401 together constitute the oil supply channel of the rod cavity of the clamp oil cylinder 4. Similarly, the first rodless cavity flow channel 1012 on the first bottom plate 101, the rodless cavity clamp oil pipe, the second rodless cavity flow channel 2022 on the second top plate 202, and the third rodless cavity flow channel 4012 on the cylinder base 401 together constitute the oil supply channel of the rodless cavity of the clamp oil cylinder 4.

[0050] It can be understood that the oil circuit of the clamp cylinder 4 enters from the bottom of the drill rig body and leads to the rod chamber and rodless chamber of the clamp cylinder 4 respectively. The reciprocating motion of the piston of the clamp cylinder 4 is realized by changing the oil inlet and return to the rod chamber and rodless chamber of the clamp cylinder 4.

[0051] In some embodiments, Figure 2 and Fig. 9 As shown, the cylinder assembly also includes a guard plate 6, which is arranged on the second top plate 202, and the clamp cylinder 4 is located between the guard plate 6 and the second top plate 202, thereby protecting the clamp cylinder 4 and preventing external factors (broken rocks, etc.) from damaging the clamp cylinder 4 during construction.
