Description

Technical Field

[0001] This application relates to the field of blast furnace front equipment technology, and in particular to a sloping rotary taphole machine. Background Technology

[0002] The hydraulic taphole opener is a key piece of equipment in the blast furnace tapping area. Its function is to open the taphole at a preset angle in the blast furnace taphole area, ensuring that high-temperature molten iron can flow smoothly out of the tapping channel. With the increasing size of blast furnaces and the increasingly compact working environment in front of the furnace, higher requirements are placed on the structural layout, operational stability, and ease of maintenance of the taphole opener.

[0003] The existing KJF type iron tapping machine mainly includes the existing drilling rig feed device 1, the hanging mechanism 2, the control linkage 3, the slewing mechanism 4, and the anchor bolt assembly 5. For example... Figure 1 As shown, the slewing mechanism 4 includes an inclined column 41, an existing rotating arm 42, a slewing bearing 43, and an existing slewing cylinder 44. The inclined column 41 is fixed to the furnace foundation by anchor bolts 5. The existing rotating arm 42 is rotatably connected to the inclined column 41 by the slewing bearing 43. The existing slewing cylinder 44 drives the existing rotating arm 42 to rotate around the rotation center. The head of the existing rotating arm 42 is connected to the hanging mechanism 2 by a small tie rod 45. One end of the control linkage 3 is connected to the inclined column 41 by a first shaft 31, and the other end is connected to the large slewing joint 21 by a second shaft 32. The hanging seat 22 is connected to the large slewing joint 21 by fasteners 23, and the existing drilling rig feed device 1 is connected to the hanging seat 22 by fasteners. During operation, the existing slewing cylinder 44 drives the existing rotating arm 42 to rotate, thereby rotating the existing drilling rig feed device 1 to the working position, using its drill bit to perform the iron-opening operation. However, the existing KJF type taphole machine has the following shortcomings in practical applications: Installation and maintenance are difficult: The slewing mechanism 4 and the foundation are an integral structure, requiring hoisting and foundation alignment during installation. Due to its large weight and size, on-site hoisting operations are cumbersome, foundation alignment is difficult, and installation, disassembly, and subsequent maintenance and replacement are inconvenient.

[0004] Highly affected by heat radiation and short service life: Due to the use of a control linkage structure, in order to avoid the iron trench and hydraulic mud gun, the existing drilling rig feed device 1 is in a folded state when in standby position and is close to the iron trench. It is subject to the heat radiation of high temperature molten iron for a long time, and the various parts of the equipment are prone to aging and damage, resulting in a shortened service life. Summary of the Invention

[0006] This application provides an inclined plane rotary taphole machine, including: An inclined base is used to fix the furnace front foundation; A rotating mechanism includes a rotating frame and a rotating arm, wherein the rotating frame is detachably connected to the inclined base, and one end of the rotating arm is hinged to the rotating frame; The hanging bracket is connected to the other end of the swing arm; The drilling rig feed device is connected to the hanging frame; The rotating mechanism also includes a rotary cylinder, a U-shaped rod, and a connecting rod. One end of the rotary cylinder is connected to the boom member, and the other end of the rotary cylinder is connected to the U-shaped rod to drive the U-shaped rod to rotate. One end of the U-shaped rod is hinged to the boom member, and the other end of the U-shaped rod is connected to the rotating frame through the connecting rod to drive the boom member to rotate relative to the rotating frame and to keep the drilling rig feed device away from the iron trench when in the standby position.

[0007] In conjunction with the first aspect, in one possible implementation, the inclined base has a preset tilt angle α so that when the drilling rig feed device is in the working position, its drill bit is aligned with the iron opening.

[0008] In conjunction with the first aspect, in one possible implementation, the tilt angle α of the inclined base is configured such that when the drilling rig feed device is in the standby position, the longitudinal axis of the drilling rig feed device is approximately horizontal.

[0009] In conjunction with the first aspect, in one possible implementation, the inclined rotary taphole machine further includes a top block centering device and a top block seat. The top block centering device is disposed at the front end of the drilling rig feed device, and the top block seat is used to fix it to the blast furnace wall. When the drilling rig feed device rotates to the working position, the top block centering device abuts against the top block seat.

[0010] In conjunction with the first aspect, in one possible implementation, the top block centering device has an elongated hole and is connected to the drilling rig feed device via a first bolt assembly, so that the position of the top block centering device can be adjusted along the longitudinal direction of the drilling rig feed device.

[0011] In conjunction with the first aspect, in one possible implementation, the front end of the swing arm is a plate-like structure, and the hanging frame is connected to the plate-like structure via a second bolt assembly.

[0012] In conjunction with the first aspect, in one possible implementation, the plate-like structure is provided with a first anti-shear pin hole; the hanging bracket is provided with a second anti-shear pin hole corresponding to the first anti-shear pin hole.

[0013] In conjunction with the first aspect, in one possible implementation, the hanging frame is provided with a plurality of first adjustment holes; the plate-like structure is provided with second adjustment holes corresponding to the first adjustment holes, for adjusting the installation angle of the drilling rig feed device.

[0014] In conjunction with the first aspect, in one possible implementation, the inclined base is provided with multiple safety blocks for positioning the rotating frame.

[0015] In conjunction with the first aspect, in one possible implementation, the rotation angle of the rotating mechanism is not less than 130°, so that the drilling rig feed device is away from the iron trench when in the standby position.

[0016] One or more technical solutions provided in the embodiments of this application have at least the following technical effects: The inclined rotary taphole machine provided in this application effectively solves the technical problems existing in the existing KJF type taphole machine by adopting a split structure in which the inclined base and the rotating frame are detachably connected, and a rotating mechanism composed of a rotary cylinder, a U-shaped rod, and a double connecting rod. Specifically, compared with the integral structure of the rotating mechanism and the foundation in the prior art, this application sets the inclined base and the rotating mechanism as separate parts. During installation, the inclined base can be aligned and fixed to the furnace foundation first, and then the rotating frame can be connected to the inclined base. This avoids the problems of overall hoisting and foundation alignment difficulties, significantly reduces the installation difficulty, and facilitates subsequent disassembly, replacement, and maintenance. Meanwhile, this application replaces the control linkage structure in the prior art with a U-shaped rod and a two-link linkage mechanism. This not only increases the rotation angle of the slewing mechanism, allowing the drilling rig's feed device to be far from the iron trench in the standby position, effectively avoiding the heat radiation effects of the high-temperature molten iron and extending the equipment's service life, but also, through optimized design of the U-shaped rod's connection points and the length of the two-link linkage, ensures that the clamping force of the rotary cylinder meets the usage requirements, improving the stability and reliability of the equipment's operation. Therefore, this application has achieved significant technological progress in simplifying installation and maintenance procedures, reducing the impact of heat radiation, and extending the equipment's service life.

[0020] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0022] This application provides an inclined plane rotary taphole machine, such as... Figures 1 to 12 As shown, the inclined rotary taphole machine includes an inclined base 7, a rotating mechanism 8, a hanging frame 9, and a drilling feed device 6. The inclined base 7 is used to fix it to the furnace foundation. The rotating mechanism 8 includes a rotating frame 81 and a rotating arm 82. The rotating frame 81 is detachably connected to the inclined base 7, and one end of the rotating arm 82 is hinged to the rotating frame 81. The hanging frame 9 is connected to the other end of the rotating arm 82. The drilling feed device 6 is connected to the hanging frame 9. The rotating mechanism 8 also includes a rotary cylinder 83, a U-shaped rod 84, and a connecting rod 85. One end of the rotary cylinder 83 is connected to the rotating arm 82, and the other end of the rotary cylinder 83 is connected to the U-shaped rod 84 to drive the U-shaped rod 84 to rotate. One end of the U-shaped rod 84 is hinged to the rotating arm 82, and the other end of the U-shaped rod 84 is connected to the rotating frame 81 through the connecting rod 85 to drive the rotating arm 82 to rotate relative to the rotating frame 81 and to keep the drilling rig feed device 6 away from the iron trench when in the standby position.

[0023] It should be noted that the inclined rotary taphole machine provided in this application, by adopting a split structure in which the inclined base 7 and the rotating frame 81 are detachably connected, and a rotating mechanism 8 composed of a rotary cylinder 83, a U-shaped rod 84, and a double connecting rod 85, effectively solves the technical problems existing in the KJF type taphole machine. Specifically, compared with the integral structure of the rotating mechanism 4 and the foundation in the prior art, this application sets the inclined base 7 and the rotating mechanism 8 as separate parts. During installation, the inclined base 7 can be aligned and fixed to the furnace foundation first, and then the rotating frame 81 can be connected to the inclined base 7. This avoids the problems of overall hoisting and foundation alignment difficulties, significantly reduces the installation difficulty, and facilitates subsequent disassembly, replacement, and maintenance. Meanwhile, this application replaces the control link 3 structure in the prior art with a linkage mechanism of U-shaped rod 84 and two connecting rods 85. This not only increases the rotation angle of the rotating mechanism 8, allowing the drilling rig feed device 6 to be away from the iron trench in the standby position, effectively avoiding the heat radiation effect of high-temperature molten iron and extending the service life of the equipment; but also, by optimizing the design of each connection point of the U-shaped rod 84 and the length of the two connecting rods 85, it ensures that the clamping force of the rotary cylinder 83 meets the usage requirements, improving the stability and reliability of the equipment operation. Therefore, this application has achieved significant technical progress in simplifying the installation and maintenance process, reducing the impact of heat radiation, and extending the service life of the equipment.

[0024] In this embodiment, the inclined base 7 has a preset tilt angle α so that when the drilling rig feed device 6 is in the working position, its drill bit 61 is aligned with the iron opening.

[0025] The tilt angle α can be designed according to the specific layout of the tapping area in front of the blast furnace, the position of the mud gun, and the adaptation requirements of the automatic rod changing device.

[0026] In this embodiment, the tilt angle α of the inclined base 7 is configured such that, while keeping the mud gun constant, the safe distance between the gun barrel and the inclined rotary taphole machine increases, such as... Figure 5 and Figure 6 As shown.

[0027] In this embodiment, the tilt angle α of the inclined base 7 is configured such that when the drilling rig feed device 6 is in the standby position, the longitudinal axis of the drilling rig feed device 6 is close to horizontal.

[0028] The preferred value range of the tilt angle α of the inclined base 7 is 15°±2° (i.e., 13°-17°). This angle is verified by the design of the blast furnace taphole layout: the angle between the center line of the blast furnace taphole and the horizontal plane is usually 10°-12°. The tilt angle α of the inclined base 7 is designed to be 15°±2°, which can ensure that the drilling axis of the drill bit 61 of the drilling rig feed device 6 is precisely aligned with the center line of the taphole when it is in the working position. At the same time, it ensures that the feeding direction of the drilling rig feed device 6 matches the force direction of the taphole refractory material, thus avoiding drilling deviation.

[0029] When α is 15°, the longitudinal axis of the drilling rig feed device 6 is 0.13° with the horizontal plane when it is in the standby position, which achieves the "near-horizontal" posture requirement and is fully compatible with the horizontal rod changing requirements of the automatic rod changing device in front of the blast furnace (the horizontal alignment tolerance of the automatic rod changing device is ±0.5°).

[0030] In this embodiment of the application, the inclined rotary taphole machine also includes a top block centering device 10 and a top block seat 11. The top block centering device 10 is disposed at the front end of the drilling rig feed device 6, and the top block seat 11 is used to fix it on the blast furnace wall. When the drilling rig feed device 6 rotates to the working position, the top block centering device 10 abuts against the top block seat 11.

[0031] In this embodiment, the top block centering device 10 has an elongated hole and is connected to the drilling rig feed device 6 via a first bolt assembly 12, allowing the position of the top block centering device 10 to be adjusted longitudinally along the drilling rig feed device 6. The elongated hole on the top block centering device 10 is a waist-shaped elongated hole.

[0032] It should be noted that, through the cooperation of the elongated hole and the first bolt assembly 12, the top block centering device 10 can be finely adjusted at the front end of the drilling rig feed device 6. Users can flexibly adjust the extension length of the top block centering device 10 according to actual site conditions (such as installation errors of the blast furnace wall, welding position deviations of the top block seat 11, etc.) to ensure accurate and stable contact with the top block seat 11 in the working position. This structure simplifies the on-site installation and commissioning process, reduces the requirements for foundation construction accuracy, avoids the problem of the top block failing to effectively contact due to installation deviations, and improves the on-site adaptability and installation efficiency of the equipment.

[0033] In this embodiment, the front end of the swing arm 82 is a plate-like structure 821, and the hanger 9 is connected to the plate-like structure 821 via a second bolt assembly 13. Through the cooperation of the first anti-shear pin hole and the second anti-shear pin hole 91, an anti-shear positioning structure is added to the bolt assembly connection. When the equipment is subjected to shear force, the mating pin in the anti-shear pin hole can bear the main shear load, effectively preventing the connecting bolts from deforming or breaking due to shearing, significantly improving the connection reliability and impact resistance between the plate-like structure 821 and the hanger 9. Simultaneously, this anti-shear positioning structure plays an auxiliary positioning role during installation, facilitating rapid alignment of the hanger 9 and the front end of the swing arm 82, simplifying the installation process, and avoiding the problems of high processing difficulty and high installation accuracy requirements caused by the use of a large rotary joint 21 in the prior art, further improving the assembly efficiency and maintenance convenience of the equipment.

[0034] In this embodiment, the plate structure 821 is provided with a first anti-shear pin hole; the hanging bracket 9 is provided with a second anti-shear pin hole 91 corresponding to the first anti-shear pin hole.

[0035] like Figure 8 As shown in this embodiment, the hanging frame 9 is provided with multiple first adjustment holes 92, and the plate-like structure 821 at the front end of the boom member 82 is provided with second adjustment holes corresponding to the first adjustment holes 92. By selecting different hole positions, the installation angle of the drilling rig feed device 6 can be flexibly adjusted to meet the requirements of different working conditions for the opening angle. As a preferred embodiment, the multiple first adjustment holes 92 are arranged at 1° intervals, so that the installation angle of the drilling rig feed device 6 can be finely adjusted in 1° increments. Combined with the preset tilt angle α of the inclined base 7, the working angle of the drill bit 61 of the drilling rig feed device 6 can be precisely adjusted within the range of 8° to 12°. This setting not only expands the working condition adaptability of the equipment and improves the accuracy and flexibility of the opening operation, but also has a simple structure and is easy to adjust, avoiding the problem of affecting the working efficiency due to the inability or difficulty of adjustment of the angle in the prior art. At the same time, the connection between the first adjustment holes 92 and the second adjustment holes enhances the reliability of the connection between the boom member 82 and the hanging frame 9, further improving the stability of the whole machine in the working state.

[0036] Specifically, the first adjustment hole 92 on the hanging frame 9 is a circular through hole, and multiple circular through holes are arranged along an arc trajectory. The center of the arc coincides with the rotation center of the rotating arm 82. The central angle between adjacent first adjustment holes 92 is 1°. Therefore, the installation angle of the drilling rig feed device 6 can be finely adjusted in 1° increments within the range of 8°-12° to adapt to the drilling angle requirements of different blast furnace tapholes.

[0037] In this embodiment, the inclined base 7 is provided with multiple safety blocks 14 for positioning the rotating frame 81. By using the safety blocks 14, when the rotating frame 81 is connected to the inclined base 7 via the third bolt assembly 71, the safety blocks 14 can provide precise limiting and rapid positioning, avoiding the tedious operation of repeatedly adjusting alignment during installation and improving on-site installation efficiency. Simultaneously, the safety blocks 14 can bear some shear force during equipment operation, enhancing the connection reliability between the rotating frame 81 and the inclined base 7, preventing loosening or displacement of the connecting bolts due to vibration or impact, ensuring the positional accuracy and stability of the rotating mechanism 8 in working condition, and further improving the overall safety and service life of the machine. Specifically, after the safety blocks 14 are adjusted to the inclined base 7 at the user's site, they are welded to the inclined base 7, with a weld height of 10mm.

[0038] In this embodiment, the rotation angle of the rotating mechanism 8 is not less than 130°, so that the drilling rig feed device 6 is away from the iron trench when in the standby position.

[0039] Specifically, this application significantly increases the rotation angle of the rotating mechanism 8 by eliminating the traditional control linkage 3 structure and optimizing parameters such as the arrangement of the rotary cylinder 83, the hinge positions of the U-shaped rod 84 and each connection point, and the length of the double linkage 85. Compared to the existing KJF type iron tapping machine, where the distance between the drilling feed device 6 and the center line of the iron trench is approximately 1500mm in the standby position, the distance between the drilling feed device 6 and the center line of the iron trench in this application can reach 3700mm, an increase of approximately 1.5 times. This structural improvement allows the drilling feed device 6 to effectively stay away from the high-temperature heat radiation area of ​​the iron trench when not in operation, greatly reducing the impact of heat on the equipment and extending the service life of various components. At the same time, the increased distance between the drilling feed device 6 and the equipment body provides more operating space for daily inspection, maintenance, and spare parts replacement, improving the maintainability of the equipment. In addition, the large rotation angle design also provides a structural basis for subsequent adaptation to an automatic rod changing device, facilitating automated operation.
