Abstract
Description
Technical Field
[0001] This invention relates to the field of mining machinery technology, and in particular to an integrated drill arm clamp for drilling and anchoring. Background Technology
[0002] Anchor bolt drilling rigs are indispensable equipment in mines, tunnels, and underground engineering, primarily used for the installation and fixing of anchor bolts to ensure the stability and safety of the project. In anchor bolt drilling rigs, clamps are typically mounted on the drill frame and their opening and closing are controlled hydraulically or mechanically. The main function of the clamps is to firmly hold the anchor bolt during drilling, preventing slippage or displacement during high-speed rotation and advancement.
[0003] In related technologies, the two external hydraulic hoses connected to the clamp cylinder reciprocate with the drill frame. However, these external clamp lines are susceptible to interference from external factors, such as the complex environment of the construction site, collisions, and abrasion, leading to a significant risk of the hydraulic hoses breaking. Damage to the hydraulic hoses not only affects the normal operation of the drill frame but may also cause safety accidents, threatening the safety of construction personnel. Furthermore, frequent replacement of hydraulic hoses increases maintenance costs and construction time. Summary of the Invention

Detailed Implementation
[0032] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.
[0033] The integrated drill arm clamp of the present invention, with reference to the accompanying drawings, is described below.
[0034] like Figures 1 to 9 As shown, the drill arm clamp of the present invention includes: a drill frame body and a clamp assembly.
[0035] The drill frame body includes a primary frame 1 and a secondary frame 2. The primary frame 1 can slide along its length direction, and the secondary frame 2 is slidably mounted on the primary frame 1 along the length direction of the primary frame 1.
[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 located 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 pipes 5 are 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 cylinder 4. The clamp oil pipes 5 include an inner pipe 501 and an outer pipe 502. The outer pipe 502 is slidably sleeved on the inner pipe 501, so that when the position of the clamp cylinder 4 on the primary frame 1 changes, it drives the outer pipe 502 and the inner pipe 501 to slide relative to each other.
[0037] Understandably, after the primary frame 1 is deployed, the secondary frame 2 moves on the primary frame 1, driving the clamp cylinder 4 and the clamp body 3 to move, and at the same time driving the clamp oil pipe 5 to extend and retract, thereby achieving normal oil supply to the clamp cylinder 4 through the extendable clamp oil pipe 5.
[0038] Therefore, the drill arm clamp of the integrated drill and anchor system in this embodiment of the invention, with the clamp tubing 5 in the form of a telescopic sleeve structure, can move synchronously with the secondary frame 2, which solves the problem of external tubing being easily snagged in related technologies and improves the reliability and safety of the device operation.
[0039] In some embodiments, such as Figure 1 and Figure 2 As shown, the primary frame 1 includes a first base 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 base plate 101, and the other end of the support plate 103 is slidably connected to the sliding column 104. The end of the sliding column 104 away from the first base plate 101 is connected to the first top plate 102.
[0040] It is understandable that the sliding of the sliding column 104 causes the first top plate 102 to move, thereby achieving the sliding of the primary frame 1. Optionally, as... Figure 1 and Figure 2 As shown, a fixing sleeve 105 is provided at the end of the support plate 103 away from the first base plate 101. The fixing sleeve 105 has a sliding hole, through which the sliding column 104 can slide to ensure the stability of the sliding and unfolding of the primary frame 1.
[0041] The secondary frame 2 is slidable between the first base plate 101 and the first top plate 102. The secondary frame 2 includes a second base plate 201, a second top plate 202, and a support column 203. The two ends of the support column 203 are connected to the second base plate 201 and the second top plate 202, respectively. For example, guide columns are provided on the secondary frame 2, and the fixing sleeve 105 on the support plate 103 also has sliding holes for the guide columns to slide, thereby enabling the secondary frame 2 to slide on the primary frame 1.
[0042] The clamp cylinder 4 is mounted on the second top plate 202, specifically, as follows: 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 outer tube 502 is connected to the second base plate 201 and the second top plate 202 at both ends, and one end of the inner tube 501 passes through the second base plate 201 and is inserted into the outer tube 502. The other end of the inner tube 501 is connected to the first base plate 101. Specifically, as shown... Figures 2 to 4As shown, the inner tube 501 has an inner tube flange 503 at one end connected to the first base plate 101. The first base plate 101 has an interface for assembling the inner tube flange 503. The two can be connected by screws, and the connection between the two is sealed. Similarly, the outer tube 502 has an outer tube flange 504 at one end connected to the second base plate 201. The second base plate 201 has an interface for assembling the outer tube flange 504. The two can be connected by screws, and the connection between the two is sealed.
[0044] Furthermore, such as Figure 4 As shown, the inner circumferential wall of the outer pipe flange 504 is provided with multiple annular sealing grooves, and a dynamic sealing ring 505 is provided in the sealing groove, thereby ensuring the sliding seal between the inner pipe 501 and the outer pipe 502.
[0045] In some embodiments, the two clamping oil pipes 5 are respectively a rod-cavity clamping oil pipe and a rodless-cavity clamping oil pipe. The rod-cavity clamping oil pipe is connected to the rod-cavity of the clamping cylinder 4, and the rodless-cavity clamping oil pipe is connected to the rodless-cavity of the clamping cylinder 4.
[0046] Optionally, such as Figure 2 and Figure 5 As shown, the first base plate 101 is provided with a first rod-shaped cavity flow channel 1011 and a first rodless cavity flow channel 1012. The inner tube 501 of the rod-shaped cavity clamp oil pipe is connected to the first rod-shaped 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-side flow channel 2021 and a second rodless-side flow channel 2022. The outer tube 502 of the rod-side clamping tubing communicates with the second rod-side flow channel 2021, and the outer tube 502 of the rodless-side clamping tubing communicates with the second rodless-side 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 on the second top plate 202 for the outer tube 502, and a static sealing ring is fitted inside the groove.
[0048] like Figure 2 and Figure 7 As shown, the cylinder base 401 is provided with a third rod cavity flow channel 4011 that communicates with the rod cavity of the clamp cylinder 4 and a third rodless cavity flow channel 4012 that communicates with the rodless cavity of the clamp cylinder 4. The cylinder base 401 is pressed and sealed with the second top plate 202. The third rod cavity flow channel 4011 communicates with the second rod cavity flow channel 2021, and the third rodless cavity flow channel 4012 communicates with the second rodless cavity flow channel 2022.
[0049] Therefore, the first rod-side flow channel 1011 on the first base plate 101, the rod-side clamping oil pipe, the second rod-side flow channel 2021 on the second top plate 202, and the third rod-side flow channel 4011 on the cylinder base 401 together form the oil supply channel for the rod-side cavity of the clamping cylinder 4. Similarly, the first rodless-side flow channel 1012 on the first base plate 101, the rodless-side clamping oil pipe, the second rodless-side flow channel 2022 on the second top plate 202, and the third rodless-side flow channel 4012 on the cylinder base 401 together form the oil supply channel for the rodless-side cavity of the clamping cylinder 4.
[0050] It is understandable that the oil passage of the clamp cylinder 4 enters from the bottom of the drill frame 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 achieved by changing the oil inlet and outlet to the rod chamber and rodless chamber of the clamp cylinder 4.
[0051] In some embodiments, such as Figure 2 and Figure 9 As shown, the hydraulic cylinder assembly also includes a guard plate 6, which is located on the second top plate 202. The clamping cylinder 4 is located between the guard plate 6 and the second top plate 202, thereby protecting the clamping cylinder 4 and preventing external factors (such as falling rocks) from damaging the clamping cylinder 4 during construction.
