Detailed Implementation

[0043] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0044] Please refer to the following: Figures 1 to 10This invention provides a converter tapping outlet maintenance device. The device includes a vehicle body 1, a support component 2, a hole-expanding mechanism 3, and a brick-mounting mechanism 4. The vehicle body 1 is equipped with a traveling device 5 and a rotating platform 6. The rotating platform 6 is rotatably mounted on the vehicle body 1. The support component 2 is mounted on the rotating platform 6 and can slide laterally along the rotating platform 6. The hole-expanding mechanism 3 is connected to the top of the support component 2 and has a hole-expanding drill bit 31 for expanding the tapping outlet. The brick-mounting mechanism 4 is connected to the top of the support component 2 and is located on one side of the hole-expanding mechanism 3. The brick-mounting mechanism 4 has a support shaft 41 for supporting the brick. When the support component 2 slides laterally, the hole-expanding mechanism 3 and the brick-mounting mechanism 4 can be in working positions, so that the hole-expanding drill bit 31 is aligned with the tapping outlet, or the brick is aligned with the tapping outlet.

[0045] This utility model provides a converter tapping outlet maintenance device. Compared with the prior art, this application integrates the functions of hole enlargement and brick replacement into one unit. Through the lateral sliding of the support component 2, the hole enlargement mechanism 3 and the brick replacement mechanism 4 can be accurately aligned to the working position, effectively solving the problem that the prior art requires the use of two sets of equipment for hole enlargement and brick replacement, resulting in long maintenance time and low efficiency. This greatly improves the work efficiency of tapping outlet maintenance and shortens the maintenance time. With the above-mentioned setting of this application, after the car body 1 is positioned, only the positions of the hole enlargement mechanism 3 and the brick replacement mechanism 4 need to be adjusted to realize the hole enlargement and brick replacement process. Compared with the prior art, this application does not require adjusting the position of the car body 1 of the two sets of equipment, which can reduce the positioning time of the car body 1 and improve the operating efficiency.

[0046] For example, the walking device 5 of the vehicle body 1 is in the form of a track. The tracked walking device 5 is the prior art and will not be described in detail here.

[0047] In some embodiments, such as Figures 1 to 10 As shown, the vehicle body 1 has multiple positioning cylinders 11, with the piston rod of each positioning cylinder 11 facing downwards; wherein, when the vehicle body 1 moves into position, the piston rod of the positioning cylinder 11 engages with the insertion hole 12 on the ground.

[0048] It should be noted that the vehicle body 1 is equipped with multiple positioning cylinders 11, with the piston rods facing downwards and engaging with the insertion holes 12 on the ground. This allows the equipment to be stably fixed in the designated position after it has moved into place, preventing displacement of the equipment due to external forces or vibrations during operation. This ensures the stability of the equipment operation, thereby guaranteeing the accuracy and reliability of the hole enlargement and brick-laying operations and improving maintenance quality.

[0049] For example, four positioning cylinders 11 are respectively set at the four corners of the vehicle body 1.

[0050] In some embodiments, such as Figures 1 to 10 As shown, there is a support beam assembly 7 between the support component 2 and the rotary platform 6, and the support component 2 is laterally slidably mounted on the support beam assembly 7; wherein, one end of the support beam assembly 7 is hinged to the rotary platform 6, and a top pushing force member 71 is provided between the support beam assembly 7 and the rotary platform 6, and both ends of the top pushing force member 71 are hinged to the support beam assembly 7 and the rotary platform 6 respectively.

[0051] It should be noted that the pushing force component 71 can be a pitch cylinder. One end of the cylinder barrel of the pitch cylinder is hinged to the rotary platform 6, and the piston rod end of the pitch cylinder is hinged to the bottom of the support beam assembly 7. There can be two pitch cylinders, which are respectively located on both sides of the bottom of the support beam assembly 7. By extending and retracting the piston rod of the pitch cylinder, the support beam assembly 7 can be driven to swing around the hinged position, thereby adjusting the angle of the support beam assembly 7.

[0052] In some embodiments, such as Figures 1 to 10 As shown, a transverse drive cylinder 72 is connected to the top of the support beam assembly 7, and the piston rod end of the transverse drive cylinder 72 is connected to the support component 2; wherein, the top of the support beam assembly 7 has a guide rail 73 arranged parallel to the transverse drive cylinder 72, and the support component 2 has a slider 74 that slides with the guide rail 73.

[0053] It should be noted that by extending or retracting the piston rod of the lateral drive cylinder 72, the support component 2 can slide laterally on the support beam assembly 7, thereby moving the hole expansion mechanism 3 to the working position, or moving the brick-setting mechanism 4 to the working position.

[0054] For example, the slider 74 is fixedly mounted on the support component 2. Through the sliding cooperation between the slider 74 and the guide rail 73, the support component 2 can be guided to ensure that the hole expansion mechanism 3 and the brick mounting mechanism 4 move stably and accurately to the working position, thereby improving the positioning accuracy and operational reliability of the equipment.

[0055] For example, the guide rail 73 and the slider 74 can be two sets or more.

[0056] In some embodiments, such as Figures 1 to 10 As shown, the reaming mechanism 3 includes a reaming slide 32, a slide assembly 33, and a reaming propulsion cylinder 34; the reaming slide 32 is connected to the top of the support member 2; the slide assembly 33 is slidably mounted on the reaming slide 32; the slide assembly 33 is provided with a power member 35, the drive end of the power member 35 is connected to a drill rod 36, and the other end of the reaming slide 32 has a support frame 37 for supporting the drill rod 36, and the drill rod 36 is rotatably engaged with the support frame 37; the reaming propulsion cylinder 34 is connected to the reaming slide 32; the piston rod of the reaming propulsion cylinder 34 is connected to the slide assembly 33.

[0057] It should be noted that the reaming propulsion cylinder 34 can drive the slide plate assembly 33 to slide on the reaming slide 32, thereby moving the drill rod 36 and the reaming drill bit 31 to the position of the steel outlet, or moving the drill rod 36 and the drill bit backward to reset; the drill rod 36 can be rotated by the power component 35, which can enable the drill bit to perform reaming operation on the steel outlet; the power component 35 can be a hydraulic motor, which drives the drill rod 36 to rotate, which can drive the reaming drill bit 31 to rotate, thereby performing reaming operation on the steel outlet.

[0058] For example, by setting a support frame 37 on the reaming slide 32, the drill rod 36 can be supported, and the drill rod 36 can be kept stable to a certain extent during the movement of the drill rod 36 on the reaming slide 32.

[0059] In some embodiments, such as Figures 1 to 10 As shown, both ends of the reaming slide 32 are equipped with fixed pulleys 38 that rotate rotatably. The reaming slide 32 is also equipped with a movable pulley group 39, which includes two movable pulleys. The piston rod of the reaming propulsion cylinder 34 is connected to the movable pulley group 39. The reaming slide 32 is also equipped with a plate chain 8. One end of the plate chain 8 is fixed to one end of the reaming slide 32 at the reaming drill bit 31. The other end of the plate chain 8 passes sequentially around one of the movable pulleys of the movable pulley group 39, the fixed pulley 38 at one end of the reaming frame at the reaming drill bit 31, the fixed pulley 38 at the other end of the reaming frame, and the other movable pulley of the movable pulley group 39. The other end of the plate chain 8 is fixed to the slide plate assembly 33.

[0060] For example, the reaming cylinder 34 is fixed inside the reaming slide 32, and the piston rod end of the reaming cylinder 34 is connected to the movable pulley group 39; when the piston rod of the reaming cylinder 34 extends, the slide plate assembly 33 slides backward and the drill rod 36 moves backward to reset; when the piston rod of the reaming cylinder 34 retracts, the slide plate assembly 33 slides forward and the drill rod 36 moves to the steel outlet position.

[0061] For example, by cooperating with the movable pulley block 39, the fixed pulley 38 and the plate chain 8, the purpose of extending the range can be achieved, that is, when the piston rod of the hole-expanding propulsion cylinder 34 extends or retracts a unit distance, the drill rod 36 can move twice the unit distance.

[0062] In some embodiments, such as Figures 1 to 10 As shown, the slide plate assembly 33 is also provided with a support frame 37 for supporting the drill rod 36, and the drill rod 36 is rotatably engaged with the support frame 37; the support frame 37 on the slide plate assembly 33 can slide with the slide plate assembly 33. Through the above arrangement, the stability of the drill rod 36 during movement can be further guaranteed.

[0063] In some embodiments, such as Figures 1 to 10As shown, the brick-setting mechanism 4 includes a brick-setting slide 42, a brick-setting fixing assembly 43, and a brick-setting pushing cylinder 44; the brick-setting slide 42 is connected to the top of the support member 2; the brick-setting fixing assembly 43 is slidably mounted on the brick-setting slide 42; the support shaft 41 is connected to the brick-setting fixing assembly 43, and the connection position between the support shaft 41 and the brick-setting fixing assembly 43 has a pushing surface; the brick-setting pushing cylinder 44 is connected to the brick-setting slide 42; the piston rod of the brick-setting pushing cylinder 44 is connected to the brick-setting fixing assembly 43.

[0064] It should be noted that the support shaft 41 and the brick fixing assembly 43 are connected by a flange 45, and the connection position of the support shaft 41 and the flange 45 forms a push surface. After the steel outlet hole is enlarged, the brick sliding frame 42 can be slid to the working position by the lateral movement of the support component 2. The brick pushing cylinder 44 drives the brick fixing assembly 43 to slide forward, so that the brick can be installed at the steel outlet position.

[0065] For example, the brick fixing assembly 43 has a sliding plate 431 that slides with the brick sliding frame 42. The sliding plate 431 is fixed on the brick fixing assembly 43, and the sliding plate 431 has a roller 432 that rotates with the brick sliding frame 42.

[0066] It should be noted that the brick fixing component 43 slides with the brick sliding frame 42 through the roller 432, which can reduce the friction between the brick fixing component 43 and the brick sliding frame 42 and improve the service life of the brick sliding frame 42.

[0067] In some embodiments, such as Figures 1 to 10 As shown, the rotary platform 6 has a safety guard 9, and a receiving space is formed between the safety guard 9 and the rotary platform 6 to accommodate the working end of the hole-expanding mechanism 3 and the working end of the brick-setting mechanism 4.

[0068] It should be noted that by setting a safety guard 9 on the rotary platform 6, and by ensuring that the working ends of the hole expansion mechanism 3 and the brick-setting mechanism 4 are both located within the accommodating space, the safety performance can be improved and safety hazards can be reduced.

[0069] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
