Description

Technical Field

[0001] This invention relates to the field of mining machinery technology, and in particular to a drill box sliding conveyor device. Background Technology

[0002] Anchor drilling rigs play a vital role in infrastructure construction and underground engineering projects, and continuous technological innovation and improvement are key to enhancing project efficiency and ensuring construction safety. However, the chain-driven structure commonly used for the movement of the drill box on the feed cylinder in related technologies has certain problems.

[0003] Specifically, the feed motion of the drill box in related technologies is typically achieved through the following structure: a shaft is installed on the peripheral wall of the hydraulic cylinder, a copper sleeve is fitted on the shaft, a guide wheel is installed outside the copper sleeve, and a chain is directly wound around the guide wheel. The chain drives the guide wheel to rotate, thereby realizing the feed motion of the drill box.

[0004] The tension of the chain is crucial to the smoothness and reliability of the drill box's feed motion. However, the chain tension in related technologies is difficult to adjust. If the chain is too tight, it will lead to accelerated wear of the chain and guide wheels, reducing the service life of the equipment; if the chain is too loose, it may cause the chain to jump during operation, affecting the feed accuracy of the drill box, and even causing safety accidents.

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 drilling box sliding conveying device of the present invention is described below with reference to the accompanying drawings.

[0034] like Figures 1 to 4 As shown, the drill box sliding conveying device of this embodiment includes: a support frame 1, a hydraulic cylinder assembly 3, and a conveying assembly.

[0035] The support frame 1 is equipped with a sliding frame 2 that can move along its length. Both the support frame 1 and the sliding frame 2 are composed of a bottom plate and a top plate, as well as a support plate connecting the two. The support plate of the support frame 1 is a telescopic plate. The telescopic design allows the position of the drill box 7 to be adjusted according to different construction needs, which increases the applicability and flexibility of the device. The sliding frame 2 moves between the bottom plate and the top plate of the support frame 1.

[0036] The hydraulic cylinder assembly 3 has a primary moving part 302a and a secondary moving part 303a. The primary moving part 302a is connected to the sliding frame 2 so that the primary moving part 302a moves and drives the sliding frame 2 to move between the first end and the second end in the length direction of the support frame 1, that is, to drive the sliding frame 2 to move between the bottom and the top of the support frame 1.

[0037] During actual construction, the top plate of the support frame 1 gradually extends to contact the rock wall, and then the first-stage moving part 302a extends to drive the sliding frame 2 from the bottom of the support frame 1 to the top of the support frame 1 until the top plate of the sliding frame 2 contacts the top plate of the support frame 1. Then the second-stage moving part 303a moves from the bottom of the sliding frame 2 to the top of the sliding frame 2.

[0038] The conveying assembly includes a chain 4, a connector 5, and a limiting member 6. The chain 4 is rotatably mounted on the secondary moving part 303a. The chain 4 is connected to the sliding frame 2 via the limiting member 6, so that the secondary moving part 303a moves while driving the chain 4 to rotate. The connector 5 is mounted on the chain 4 and is used to connect to the drill box 7, thereby enabling the chain 4 to drive the drill box 7 to move.

[0039] like Figure 2 As shown, in the initial state, the drill box 7 is located at the bottom of the device. Figure 3 As shown, in the working state, the drill box 7 is moved to the top of the device by the extension and retraction of the support frame 1, the extension and retraction of the hydraulic cylinder assembly 3, and the rotation of the chain 4.

[0040] Understandably, in underground engineering, tunnel excavation, or slope stabilization construction, the drilling height may vary from the ground surface to higher rock faces. The drill box 7 can move from the bottom to the top, ensuring effective drilling operations at different heights.

[0041] Furthermore, the connector 5 and the limiting member 6 together divide the chain 4 into a first segment 401 and a second segment 402. The end of the first segment 401 and / or the second segment 402 connected to the connector 5 is movable, and its direction of movement is parallel to the straight portion of the chain 4. By adjusting the position of the end of the chain 4, the tension of the chain 4 can be adjusted.

[0042] Therefore, the drill box sliding conveying device of this embodiment of the invention can adjust the tension of the chain 4 in real time according to actual construction needs, thereby ensuring the smoothness and reliability of the feed movement of the drill box 7, improving construction efficiency and reducing equipment failure rate.

[0043] In some embodiments, such as Figures 1 to 4 As shown, the connector 5 includes a mounting base 501, a fixed block 502, and a movable block 503. The fixed block 502 and the movable block 503 are spaced apart on the mounting base 501, and the movable block 503 is movable on the mounting base 501. The fixed block 502 is connected to the end of the first segment 401 of the chain 4, and the movable block 503 is connected to the end of the second segment 402 of the chain 4.

[0044] Understandably, the tension of the chain 4 can be adjusted by changing the distance between the movable block 503 and the fixed block 502. For example, increasing the distance between the movable block 503 and the fixed block 502 decreases the tension of the chain 4. Conversely, shortening the distance between the movable block 503 and the fixed block 502 increases the tension of the chain 4.

[0045] Optionally, such as Figures 1 to 4As shown, the connector 5 also includes an adjusting bolt 505 and a support block 504. The support block 504 is mounted on the mounting base 501, and the movable block 503 is located between the fixed block 502 and the support block 504. The support block 504, the movable block 503, and the fixed block 502 are each provided with screw holes for engaging the adjusting bolt 505, so that the adjusting bolt 505 rotates and drives the movable block 503 to move, thereby improving the convenience of adjusting the tension of the chain 4.

[0046] Furthermore, a fastening nut 506 is provided at the end of the adjusting bolt 505, and the fastening nut 506 is located on the side of the support block 504 away from the movable block 503. After the tension of the chain 4 is adjusted, the fastening nut 506 is screwed on to press the support block 504, so as to fix the adjusting bolt 505 and improve the stability of the structure.

[0047] In some embodiments, such as Figures 1 to 5 As shown, the mounting base 501 is provided with a sliding hole 5011, and the sliding frame 2 is provided with a guide post 201 that passes through the sliding hole 5011.

[0048] Understandably, the drill box 7 is mounted on the chain 4 via the connector 5. As the chain 4 rotates and drives the drill box 7 to move, the guide post 201 assists in the movement, thereby improving the stability and safety of the drill box 7's movement.

[0049] In some embodiments, such as Figures 2 to 9 As shown, the limiting component 6 includes a locking block 601, and the sliding frame 2 has a locking groove, in which the locking block 601 is engaged. The groove wall and the locking block 601 are provided with corresponding first mounting holes 602, and bolts are installed in the first mounting holes 602 to achieve a detachable connection between the locking block 601 and the sliding frame 2, facilitating maintenance operations.

[0050] Optionally, the locking block 601 is provided with two mounting slots, which correspond one-to-one with the first segment 401 and the second segment 402 of the chain 4. A movable block 603 is provided within each mounting slot, with a gap 604 between the movable block 603 and the corresponding slot wall, allowing the movable block 603 to move within a certain range within the mounting slot. The movable block 603 is provided with a second mounting hole 605, allowing the pin of the chain 4 to be mounted within the second mounting hole 605.

[0051] Among them, the movable block 603 assembled to the second segment 402 of chain 4 has a gap 604 between it and the groove wall of the assembly groove, such as Figure 9 The area indicated in the diagram has a force-measuring element, such as a pressure plate of a sensor, installed within the gap 604, to detect the force on the second segment 402 of the chain 4. Similarly, the first segment 401 of the chain 4 is also subjected to force measurement in the same manner.

[0052] Therefore, based on the test results, the force on each segment of chain 4 is adjusted in real time to ensure that the force is consistent and to avoid excessive load on one side of chain 4 due to unbalanced loading.

[0053] Furthermore, the locking block 601 is provided with a baffle 606, which contacts the pin installed in the second mounting hole 605, thereby blocking the pin and preventing the pin from coming out during movement.

[0054] In some embodiments, such as Figures 1 to 3 As shown, the hydraulic cylinder assembly 3 is arranged along the length of the support frame 1. The hydraulic cylinder assembly 3 includes a hydraulic cylinder rod 301, a primary cylinder 302b, and a secondary cylinder 303b.

[0055] One end of the cylinder rod 301 is connected to the base plate of the support frame 1, and the other end of the cylinder rod 301 is slidably installed inside the first-stage cylinder 302b. The two ends of the first-stage cylinder 302b are connected to the base plate and the top plate of the sliding frame 2, respectively. That is, the cylinder rod 301 slides through the base plate of the sliding frame 2 and connects to the base plate of the support frame 1.

[0056] The secondary cylinder 303b is slidably mounted on the primary cylinder 302b. The length of the secondary cylinder 303b is greater than half the distance between the bottom plate and the top plate of the sliding frame 2. The secondary cylinder 303b moves between the bottom plate and the top plate of the sliding frame 2.

[0057] It is understood that the first-stage cylinder 302b is the first-stage moving part 302a of the hydraulic cylinder assembly 3, and the second-stage cylinder 303b is the second-stage moving part 303a of the hydraulic cylinder assembly 3. The cylinder rod 301 extends so that the first-stage cylinder 302b drives the sliding frame 2 to move between the top plate and the bottom plate of the support frame 1, and the second-stage cylinder 303b moves between the top plate and the bottom plate of the sliding frame 2.

[0058] Therefore, the drill box sliding conveying device of this invention adopts a two-stage hydraulic cylinder, which shortens the length of the hydraulic cylinder while increasing the number of hydraulic cylinders, thereby improving the space utilization of the device.

[0059] In some embodiments, such as Figure 2 and Figure 3 As shown, the two ends of the secondary cylinder 303b are respectively provided with mounting shafts for the chain 4 to rotate around, and a rotating component is provided between the chain 4 and the mounting shaft, thereby improving the rotation effect of the chain 4.

[0060] For example, the rotating component is a guide wheel, and the chain 4 is wrapped around the guide wheel. Preferably, the rotating component is a roller bearing, and the chain 4 is wrapped around the roller bearing. A positioning sleeve is provided on the side of the roller bearing near the secondary cylinder 303b, and a retaining ring is provided on the side of the roller bearing away from the secondary cylinder 303b.

[0061] Understandably, the locating sleeve and retaining ring prevent the roller bearing from moving axially on the mounting shaft due to vibration or axial force, thus avoiding bearing detachment or displacement. The retaining ring and locating sleeve also work together to seal the roller bearing, preventing lubricant leakage and maintaining the bearing's internal lubrication.

[0062] Furthermore, by using cylindrical roller bearings instead of guide wheels, rolling friction is replaced by sliding friction, which significantly reduces the coefficient of friction, reduces energy consumption, reduces wear, and extends the service life of the positioning sleeve.

[0063] In some embodiments, such as Figure 2 and Figure 3 As shown, the connection between the limiting member 6 and the sliding frame 2 is located in the middle of the sliding frame 2.

[0064] It is understandable that setting the connection point between the limiting member 6 and the sliding frame 2 in the middle of the sliding frame 2 helps to distribute the force evenly, reduce structural deformation caused by eccentric loading, and thus improve the stability and service life of the entire moving device.

[0065] And, as Figure 1 As shown, there are two conveying assemblies, which are respectively disposed on both sides of the secondary moving part 303a.

[0066] Understandably, the symmetrical arrangement of two conveying components on both sides of the secondary cylinder 303b ensures the balance of the drill box 7 during movement and reduces vibration and noise caused by uneven weight distribution.

[0067] Therefore, the optimized position of the limiting component 6 and the symmetrical arrangement of the conveying components have enhanced the mechanical strength and durability of the entire device, making it adaptable to complex and ever-changing construction environments.
