Description

Technical Field

[0001] The utility model belongs to the technical field of smelting equipment, and particularly relates to an eye-opening machine. Background Art

[0002] During the smelting process of industrial silicon in a submerged arc furnace, when the molten silicon reaches discharge standards, a hole opening device is required to open the furnace hole at the bottom of the furnace before the silicon water can be discharged. Currently, furnace operators typically perform this task by handheld, simple burn-through operating levers or by manipulating the relevant equipment. The main methods for opening the hole are carbon rod burn-through and drill rod drilling. However, when the material used to block the hole is poorly burn-through, the only option left is drill rod drilling.

[0003] Due to spatial constraints imposed by the initial construction of industrial silicon submerged arc furnaces, most current submerged arc furnace platforms lack space for a curved track-mounted drill. Even if space were available to add a new curved track-mounted drill, it would directly impact production and increase fixed asset investment. Therefore, post-furnace drilling is currently primarily performed manually using simple drill rigs. These drill rigs, however, suffer from numerous labor requirements and inconvenience in relocation, high drilling reaction forces, and complex adjustments to the drill position, resulting in low efficiency and high time costs associated with drilling. Utility Model Content

[0004] In view of the current technical problems, the utility model aims to provide a hole-opening machine, which can solve the problem that a simple drilling rig hole-opening machine requires many people to move and is inconvenient to move.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] An eye-opening machine includes an eye-opening device, and its structural characteristics are: it also includes a crawler chassis and a mounting platform arranged on the top of the crawler chassis, the mounting platform is fixedly connected to the crawler chassis through a slewing support, and the eye-opening device is arranged on the mounting platform.

[0007] The crawler chassis is a commercially available product. A slewing support is installed on the crawler chassis to enable the eye opening device to swivel, making it easier to adjust the eye opening device to the appropriate angle for eye opening operations. By installing a crawler chassis at the bottom of the eye opening device, the entire machine can move freely and be moved, thus solving the problem of requiring many people to move the eye opening machine and the inconvenience of moving the machine, and improving the efficiency of eye opening operations.

[0008] Preferably, the slewing support is provided on the top of the intermediate frame of the crawler chassis, and a plurality of rotatably connected support devices are provided on the front and rear sides of the intermediate frame. The support devices are rotated downward to support the ground so that the intermediate frame maintains a certain distance from the ground, or the support devices are rotated upward to separate from the ground. By providing the support devices, the vertical height of the entire eye-opening machine can be easily adjusted.

[0009] Preferably, four supporting devices are provided, and the four supporting devices are symmetrically arranged on the front and rear sides of the middle frame.

[0010] Preferably, the support device includes a cylinder, a support base, and a support shell, wherein the cylinder is disposed within the space enclosed by the support shell; one end of the cylinder and the support shell are both rotatably connected to the intermediate frame, and the output end of the cylinder and the other end of the support shell are both rotatably connected to the support base. When the output end of the cylinder extends outward, the support shell rotates downward around the intermediate frame and drives the support base to move downward and contact the ground, thereby increasing the overall height of the eye-opening machine. When the output end of the cylinder contracts inward, the support shell rotates upward around the intermediate frame and drives the support base to move upward and away from the ground, thereby lowering the overall height of the eye-opening machine.

[0011] Preferably, the oil cylinder and one end of the support shell are hinged to different positions of the intermediate frame, and the output end of the oil cylinder and the other end of the support shell are hinged to the same position of the support base plate.

The mounting seat is fixedly connected to the mounting platform. The output end of the first power unit is connected to the slide. The slide moves back and forth along the mounting seat under the drive of the first power unit, and the drill rod moves back and forth along the length direction under the drive of the second power unit. The first power unit facilitates the movement of the drill bit to the furnace eye, providing a pre-tightening force for the drill bit to drill into the eye. The second power unit facilitates the cutting action of the drill bit when drilling the furnace eye. Under the reaction force of drilling, the eyelet opening device can achieve the function of drilling the furnace eye.

[0013] Specifically, the center line of the mounting seat along the length direction is parallel to the center line of the drill rod, and the first power unit is arranged at the bottom of the mounting seat.

[0014] Preferably, a lifting screw is provided on the mounting platform, the output end of which is hinged to the bottom of the mounting base. The lifting screw is provided to facilitate adjustment of the lifting height of the eye-opening device, thereby adjusting the eye-aligning position of the drill bit.

[0015] Preferably, the mounting platform is provided with a pitching oil cylinder, the output end of which is hinged to the bottom of the mounting base. By providing the pitching oil cylinder, it is convenient to adjust the pitch angle of the eye-opening device, thereby adjusting the eye-aligning position of the drill bit.

[0016] Preferably, the mounting platform is provided with a control system, which is electrically connected to the eye opening device and the power unit of the crawler chassis. By providing the control system, automated operation is facilitated, thereby improving the efficiency of the eye opening operation.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1. The eye-opening machine of the present invention realizes free movement and movement of the whole machine by setting a crawler chassis, thereby solving the problem of large number of personnel required for the eye-opening machine transfer and inconvenience in moving the machine, and improving the work efficiency of the eye-opening operation.

[0019] 2. The eye-drilling machine of the present invention has a small drilling reaction force and is easy to adjust the eye-aligning position of the drill bit, thereby improving the work efficiency of the eye-drilling operation and reducing time costs. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0026] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with the embodiments. It should be noted that the embodiments and features of the embodiments of the present invention may be combined unless they conflict. For ease of description, the words "upper," "lower," "left," and "right" appear below merely to indicate the directions of upper, lower, left, and right in the accompanying drawings and do not limit the structure.

[0027] like Figure 1 As shown, an eye-opening machine according to this embodiment includes an eye-opening device 1, a crawler chassis 2, a mounting platform 3 mounted on top of the crawler chassis 2, and a control system 8. The control system 8 is electrically connected to the eye-opening device 1 and the power unit of the crawler chassis 2. The mounting platform 3 is fixedly connected to the crawler chassis 2 via a slewing support 4. The mounting platform 3 has a circle of tapped holes on the bottom and is connected to the slewing support 4 via assembly bolts. The eye-opening device 1 is mounted on the mounting platform 3, and the slewing support 4 is provided to enable the eye-opening device 1 to rotate.

[0028] The crawler chassis 2 is an existing commercial product, such as Figure 2 and Figure 3 As shown, the crawler chassis 2 includes an intermediate frame 201 and left and right crawler tracks 202 and 203 mounted on either side of the intermediate frame 201. A slewing support 4 is mounted on top of the intermediate frame 201, providing the crawler chassis 2 with free-range travel. Four pivotally connected support devices 5 are symmetrically mounted on the front and rear sides of the intermediate frame 201, enabling the overall lifting and lowering of the entire machine. The support devices 5 include a cylinder 501, a support base 502, and a support housing 503. The cylinder 501 is located within the space enclosed by the support housing 503. One end of the cylinder 501 and the support housing 503 are hingedly connected to the intermediate frame 201 at different locations. The output end of the cylinder 501 and the other end of the support housing 503 are hingedly connected to the support base 502 at the same location. When the output end of the cylinder 501 extends outward, the support housing 503 pivots downward, supporting the support base 502 on the ground, thereby maintaining a certain distance between the intermediate frame 201 and the ground. When the output end of the oil cylinder 501 contracts inward, the support shell 503 rotates upward to separate the support base plate 502 from the ground, thereby reducing the distance between the intermediate frame 201 and the ground.

[0029] like Figure 4 As shown, the eye opening device 1 includes a mounting base 101, a first power unit 102, a slide 103 slidably connected to the mounting base 101, a second power unit 106 disposed on the slide 103, a drill rod 104 connected to the output end of the second power unit 106, and a drill bit 105 disposed at the outer end of the drill rod 104. Figure 1As shown, the mounting platform 3 is provided with a lifting screw 6 and a pitching cylinder 7. The output end of the lifting screw 6 is hinged to the bottom of the mounting base 101, and the output end of the pitching cylinder 7 is hinged to the bottom of the mounting base 101. The provision of the lifting screw 6 facilitates adjustment of the lifting height of the eye-opening device 1, and the provision of the pitching cylinder 7 facilitates adjustment of the pitch angle of the eye-opening device 1, thereby facilitating adjustment of the eye-alignment position of the drill bit 105. The first power unit 102, which is a jacking cylinder, is disposed at the bottom of the mounting base 101. The output end of the first power unit 102 is connected to the slide 103, which is driven by the first power unit 102 to move back and forth along the length of the mounting base 101. The second power unit 106, which is a power head, is driven by the second power unit 106 to move the drill rod 104 back and forth along the length, with the centerline of the mounting base 101 along the length parallel to the centerline of the drill rod 104.

[0030] When the eye-opening machine of this embodiment is used, the whole machine is moved to the side of the ore-blast furnace by the crawler chassis 2, the height of the whole machine is adjusted by the support device 5, the rotation angle of the eye-opening device 1 is adjusted by the slewing support 4, the height of the eye-opening device 1 is adjusted by the lifting screw 6, and the pitch angle of the eye-opening device 1 is adjusted by the pitch cylinder 7, so that the center line of the drill bit 105 points to the furnace eye and the furnace core, and the eye-aligning operation is completed. Start the first power unit 102, and the slide 103 is driven by the first power unit 102 to move toward the ore-blast furnace along the length direction of the mounting seat 101, so that the drill bit 105 moves to the furnace eye. Start the second power unit 106, and the drill rod 104 is driven by the second power unit 106 to move toward the ore-blast furnace along the length direction, so that the drill bit 105 cuts and drills into the furnace eye to complete the eye-opening operation. After the eye-opening operation is completed, the drill bit 105 is retracted, and the whole machine is moved to another site by the crawler chassis 2. The eye-drilling machine of this embodiment can solve the problems of requiring many people to move the machine to another site, inconvenient machine movement, large drilling reaction force, and troublesome eye position adjustment during simple drilling rig operations, thereby improving the efficiency of eye-drilling operations.
