Description

Technical Field

[0001] This utility model relates to the field of mining equipment technology, specifically a rock hydraulic splitting device. Background Technology

[0002] Hydraulic rock splitting is a technique that utilizes the immense force generated by high-pressure fluid (usually hydraulic oil) to overcome the tensile strength of rock, causing it to split in a predetermined direction. A hydraulic rock splitting device is the specific equipment used to achieve this technique. It is a complete system comprising components such as a hydraulic pump station, a hydraulic rock splitter, hydraulic piping, and a control system.

[0003] For example, a hydraulic rock splitting device described in patent CN220555963U describes a scheme where several working holes are pre-drilled into the rock using drilling equipment. The operator holds the handle and gradually inserts the splitting gun into the working holes. When the bottom of the support plate touches the rock surface, the buffer pad is also pressed between the ground and the splitting machine body. At this time, the splitting gun is fully inserted into the working holes. The operator passes two hot-pressed oil pipes connected to the hydraulic cylinder through the wiring holes on the two limit plates and connects them to the two hot-pressed oil pipe interfaces on the splitting machine body. The hot-pressed oil pump is started. During the splitting process, the force generated by the splitting operation causes the splitting machine body to vibrate. Under the buffer of the buffer pad, support plate, connecting rod, shock-absorbing sleeve and spring, the vibration amplitude is small, and the operator's hand holding the handle is protected.

[0004] The aforementioned technologies have the following drawbacks: when using a splitting device, because the splitting device is usually long, it is not convenient to store. The slender device requires a large storage space, especially in environments with limited space such as construction sites or equipment warehouses. At the same time, during the use of the splitting device, it is easy for fragments of stone to fly, which can cause injury to the operator. Utility Model Content

Detailed Implementation

[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0030] In one embodiment, such as Figures 1-4As shown, a rock hydraulic splitting device includes: a top plate 100, a hydraulic cylinder 200, a support base 300, a rotating base 401, and an arc-shaped wedge 404. The hydraulic cylinder 200 is installed at the bottom of the top plate 100, the support base 300 is located below the top plate 100, the rotating base 401 is installed on both sides of the bottom of the support base 300, and the arc-shaped wedge 404 is located below the support base 300. A rotating rod 402 is rotatably connected inside the rotating base 401, and connecting rods 403 are fixedly connected to both ends of the outer wall of the rotating rod 402. The two connecting rods 403 are fixedly connected to the outer wall of the arc-shaped wedge 404. The hydraulic cylinder 200... The output end of the 00 is threadedly connected to a square wedge 405. The two sides of the square wedge 405 are respectively in contact with the sides of two arc wedges 404 that are close to each other. After the hydraulic cylinder 200 is started, it drives the square wedge 405 threadedly connected to it to move downward. The two sides of the square wedge 405 abut against the two arc wedges 404. The arc wedges 404 are forced to expand outward by the inclined surface extrusion, thereby expanding and destroying the rock. When it is necessary to store it, the arc wedges 404 can be rotated, so that the arc wedges 404 drive the connecting rod 403 to rotate inside the rotating seat 401 and rotate 180 degrees until it is parallel to the hydraulic cylinder 200.

[0031] The top plate 100 is provided with a fixing component for fixing the arc wedge block 404;

[0032] The outer wall of the hydraulic cylinder 200 is provided with a protective component for blocking gravel.

[0033] In one embodiment, such as Figure 1 and Figure 2 As shown, the fixing assembly includes a sliding column 501, which is slidably connected to both sides inside the top plate 100. A spring 502 is installed on the outer wall of the sliding column 501, and the other end of the spring 502 is fixedly connected to the bottom of the top plate 100. A limit plate 503 is installed at the top of the sliding column 501, and the bottom of the arc wedge block 404 is provided with a slot 504 corresponding to the position of the sliding column 501. By pulling the sliding column 501 upward, the sliding column 501 slides inside the top plate 100. Then, the arc wedge block 404 is folded to be placed parallel to the hydraulic cylinder 200, which releases the sliding column 501. Under the action of the spring 502, the sliding column 501 moves downward and is locked into the inside of the slot 504. The bottom end of the spring 502 abuts against the arc wedge block 404 to fix the arc wedge block 404.

[0034] In one embodiment, such as Figure 1 and Figure 2As shown, the protective assembly includes a sleeve 601, which is installed on the outer wall of the hydraulic cylinder 200. Supports 602 are installed on both sides of the bottom of the sleeve 601. A rotating column 603 is rotatably connected inside the support 602. A protective plate 604 is fixedly connected to the outer wall of the rotating column 603. A drive assembly for driving the rotating column 603 to rotate is provided on the support 602. When using the splitting device, the protective plate 604 prevents flying debris from injuring the operator. By driving the rotating column 603 to rotate, the protective plate 604 rotates synchronously, enabling the retraction and deployment of the protective plate 604.

[0035] In one embodiment, such as Figure 2 and Figure 4 As shown, the drive assembly includes two worm gears 701, which are mounted on one end of the rotating column 603. The worm gears 701 are meshed with a worm 702. A support plate 704 is mounted on the top of the bracket 602. The worm 702 is rotatably connected to the inside of the support plate 704. A handle 703 is mounted on the top of the worm 702. By rotating the handle 703, the worm 703 is driven to rotate, thereby driving the worm gears 702 to rotate, so that the protective plate 504 unfolds from the folded state into a vertical barrier, thereby better preventing flying debris from injuring the operator.

[0036] In one embodiment, such as Figure 1 and Figure 3 As shown, a groove 801 is provided on the outer wall of the bottom of the arc wedge 404, and an elastic rope is provided inside the groove 801; by placing the elastic rope inside the groove 801, it is easy to fasten the two arc wedges 404.

[0037] In one embodiment, such as Figure 1 As shown, a handle is installed on the top of the top plate 100; the handle provides a portable carrying function.

[0038] In one embodiment, such as Figure 3 As shown, the output end of the hydraulic cylinder 200 is provided with a threaded protrusion 802, and the inside of the square wedge 405 is provided with a threaded groove that matches the threaded protrusion 802; by the cooperation of the threaded protrusion 802 and the threaded groove, square wedges 405 of different sizes or wear levels can be quickly replaced, which is convenient for storage.

[0039] In one embodiment, such as Figure 1 and Figure 3 As shown, the support base 300 is I-shaped, which facilitates the rotation of the arc-shaped wedge block 404.

[0040] The above embodiment discloses a rock hydraulic splitting device, wherein after the hydraulic cylinder 200 is started, it drives the square wedge 405 threadedly connected to it to move downward. The two sides of the square wedge 405 abut against two arc wedges 404. The arc wedges 404 are forced to unfold outward by the inclined surface extrusion, thereby achieving expansion and destruction of the rock. At the same time, by rotating the handle 703, the worm gear 703 is driven to rotate, thereby driving the worm wheel 702 to rotate, so that the protective plate 504 unfolds from the folded state into a vertical barrier, thereby better preventing flying debris from injuring the operator.

[0041] When storage is required, the arc wedge block 404 can be rotated, causing the connecting rod 403 to rotate inside the rotating seat 401 and rotate 180 degrees until it is parallel to the hydraulic cylinder 200. By pulling the sliding column 501 upward, the sliding column 501 can slide inside the top plate 100. Then, the arc wedge block 404 can be folded to be placed parallel to the hydraulic cylinder 200, which will release the sliding column 501. Under the action of the spring 502, the sliding column 501 moves downward and is locked into the inside of the slot 504. The bottom end of the spring 502 abuts against the arc wedge block 404 to fix the arc wedge block 404.
