Description

Technical Field

[0001] This utility model relates to the field of metallurgy, specifically to a dismantling device for a refining vacuum tank. Background Technology

[0002] The refining vacuum tank is a key piece of equipment in the ladle refining process. Its lining is made of refractory material. After a certain period of use, the lining of the refining vacuum tank will inevitably be severely corroded. Therefore, after the refining vacuum tank has been in service, the lining of the refining vacuum tank needs to be repaired and the remaining refractory material needs to be removed. At present, steel companies usually use manual hand-held pneumatic picks to complete the dismantling of the refining vacuum tank. During the dismantling, the labor intensity of the workers is extremely high, and a large amount of dust is generated during the dismantling of the refractory material. The working environment is harsh and there are significant safety hazards. Utility Model Content

[0004] To achieve the above objectives, this utility model provides a dismantling device for a refining vacuum tank, comprising a fixed frame, a traveling mechanism, and a working mechanism. The fixed frame is equipped with a track assembly, which includes two spaced-apart tracks. The traveling mechanism includes a traveling vehicle body, rollers, a drive structure, a power source assembly, and a rotating shaft. Rollers are provided on both sides of the traveling vehicle body, and the rollers are mounted on the tracks of the fixed frame. Drive structures are provided on both sides of the traveling vehicle body, and these drive structures can drive the traveling vehicle body to reciprocate on the tracks. The power source assembly is located inside the traveling vehicle body and connected to the drive assembly. The rotating shaft is located at the bottom of the traveling vehicle body. The working mechanism includes a telescopic arm, a hammer, a steering structure, and a swinging structure. One end of the telescopic arm is hinged to the hammer, and the other end is hinged to the steering structure. The steering structure is rotatably connected to the rotating shaft at the bottom of the traveling vehicle body, and the steering structure can drive the telescopic arm to rotate along the axis of the rotating shaft. The swinging structure is mounted on the telescopic arm, and the swinging structure can drive the telescopic arm to swing up and down.

[0005] Furthermore, the track assembly also includes a rack, and racks are respectively provided on the sides of the two tracks. The drive structure includes a drive shaft and a drive gear. One end of the drive shaft is connected to the power source assembly, and the other end is connected to the drive gear. The drive gear meshes with the rack.

[0006] Furthermore, the steering structure includes a steering shaft, a steering gear, and a steering disk. The steering disk is rotatably connected to a rotating shaft at the bottom of the vehicle body. One end of the steering shaft is connected to a power source assembly, and the other end is connected to the steering gear. The steering gear and the steering disk mesh with each other.

[0007] Furthermore, the walking vehicle mechanism is also equipped with a hydraulic power component. The swing structure includes a swing hydraulic cylinder.

[0012] 1. By setting up a fixed frame, a traveling mechanism, and a working mechanism, the staff can directly control the dismantling device to dismantle the refining vacuum tank, reducing the input of personnel and effectively reducing the labor intensity and safety risks of the operators.

[0013] 2. By setting a locking structure, when the hammer head disassembles the refining vacuum tank, the lining of the refining vacuum tank will generate a reverse impact force on the hammer head, telescopic arm and the traveling vehicle body. The locking structure can offset the reverse impact force.

[0014] 3. When dismantling the refining vacuum tank, a large amount of dust will be generated. By setting up a power source component, a hydraulic power component, a telescopic hydraulic cylinder and a swing hydraulic cylinder, the operators can operate remotely away from the harsh working environment, which protects the safety of the operators to a certain extent and improves the efficiency of the operation.

[0026] See Figures 1 to 5This utility model provides a dismantling device for a refining vacuum tank, including a fixed frame 1, a traveling mechanism 2, and a working mechanism 3. The fixed frame 1 is equipped with a track assembly, which includes two spaced-apart tracks 101 that can support the traveling mechanism 2. The traveling mechanism 2 includes a traveling body 201, rollers 202, a drive structure 203, a power source assembly, and a rotating shaft. Rollers 202 are provided on both sides of the traveling body 201 and are mounted on the tracks 101 of the fixed frame 1. Drive structures 203 are provided on both sides of the traveling body 201 and can drive the traveling body 201 to reciprocate along the tracks 101 via the rollers 202. The power source assembly is located inside the traveling body 201 and is connected to the drive assembly. The connection is made so that the power source component can provide power to the drive component. The rotating shaft is set at the bottom of the walking vehicle body 201. The working mechanism 3 includes a telescopic arm 301, a hammer head 302, a steering structure 303 and a swing structure 304. One end of the telescopic arm 301 is hinged to the hammer head 302 and the other end is hinged to the steering structure 303. The steering structure 303 is rotatably connected to the rotating shaft at the bottom of the walking vehicle body 201 and can drive the telescopic arm 301 to rotate along the axis of the rotating shaft. The swing structure 304 is set on the telescopic arm 301 and can drive the telescopic arm 301 to swing up and down. Preferably, the bottom of the fixed frame 1 is also provided with a clamp. The clamp can fix the fixed frame 1 to the refining vacuum tank, which can improve the stability of the dismantling device during operation.

[0027] The basic working principle of the dismantling device for the refining vacuum tank involved in this utility model is as follows: By setting up a fixed frame 1 and a traveling vehicle mechanism 2, the driving structure 203 can drive the traveling vehicle body 201 to reciprocate on the track assembly of the fixed frame 1 via rollers 202. By setting up a working mechanism 3, when the hammer 302 contacts the inner lining of the refining vacuum tank, it can dismantle the refractory material. The telescopic arm 301, the steering structure 303, and the swing structure 304 can drive the hammer 302 to contact the inner lining of the refining vacuum tank at any position. When using the dismantling device, the refining vacuum tank to be dismantled is placed in the working position, the dismantling device is hoisted onto the refining vacuum tank and fixed. After starting, the operator can directly control the dismantling device to dismantle the refining vacuum tank. Only one person is needed to operate the entire process. This not only realizes the mechanical dismantling of the refining vacuum tank, greatly reducing personnel input and significantly reducing labor intensity, but also avoids the safety hazards caused by manual operation.

[0028] See Figures 1 to 5 The present invention will be further described below with reference to a specific embodiment:

[0029] In this embodiment, see Figure 1 and Figure 2 As a preferred design, the track assembly also includes a rack 102, and racks 102 are respectively provided on the sides of the two tracks 101. The drive structure 203 includes a drive shaft 231 and a drive gear 232. One end of the drive shaft 231 is connected to the power source assembly, and the other end is connected to the drive gear 232. The drive gear 232 meshes with the rack 102. By setting the drive gear 232 and the rack 102, the entire structure becomes more compact, and the transmission is accurate, with high transmission precision, smooth operation, and high reliability.

[0030] In this embodiment, see Figure 3 and Figure 4 As a preferred design, the steering structure 303 includes a steering shaft, a steering gear 331, and a steering disk 332. The steering disk 332 is rotatably connected to a rotating shaft at the bottom of the vehicle body 201. One end of the steering shaft is connected to the power source assembly, and the other end is connected to the steering gear 331. The steering gear 331 and the steering disk 332 mesh with each other and can be remotely controlled. By setting the steering gear 331 and the steering disk 332, the telescopic arm 301 can rotate 360° along the axis of the rotating shaft.

[0031] In this embodiment, see Figure 3 and Figure 4 As a preferred design, the walking vehicle mechanism 2 is also equipped with a hydraulic power component. The swing structure 304 includes a swing hydraulic cylinder. One end of the swing hydraulic cylinder is hinged to the outer peripheral surface of the telescopic arm 301, and the other end is hinged to the steering gear 332. The swing hydraulic cylinder is connected to the hydraulic power component. When the hydraulic power component drives the swing hydraulic cylinder to reciprocate, it can drive the telescopic arm 301 to swing up and down. The swing hydraulic cylinder can be remotely controlled and has good load-bearing capacity.

[0032] In this embodiment, see Figure 1 , Figure 4 and Figure 5 As a preferred design, the telescopic boom 301 includes a telescopic hydraulic cylinder, one end of which is hinged to the hammer head 302 and the other end is hinged to the steering structure 303. The telescopic hydraulic cylinder is connected to a hydraulic power assembly, which can drive the telescopic hydraulic cylinder to reciprocate, so that the hammer head 302 can extend into the refining vacuum tank. The telescopic hydraulic cylinder can also be remotely controlled.

[0033] In this embodiment, see Figure 1 and Figure 3As a preferred design, the traveling vehicle mechanism 2 also includes several locking structures 204. One end of the locking structure 204 is fixedly mounted on the traveling vehicle body 201, and the other end abuts against the bottom of the track 101. When the hammer 302 disassembles the refining vacuum tank, the lining of the refining vacuum tank will generate a reverse impact force on the hammer 302, the telescopic arm 301 and the traveling vehicle body 201. The reverse impact force can be offset by setting the locking structure 204. Preferably, two locking structures 204 are respectively provided on both sides of the traveling vehicle body 201.

[0034] In this embodiment, see Figure 1 As a preferred design, the power source components include an electric motor, which is small in size, highly reliable, and capable of remote control.

[0035] As can be seen from the above, the dismantling device for the refining vacuum tank of this utility model has the following beneficial effects:

[0036] 1. By setting up a fixed frame 1, a traveling mechanism 2 and a working mechanism 3, the staff can directly control the dismantling device to dismantle the refining vacuum tank, which reduces the input of personnel and can effectively reduce the labor intensity and safety risks of the operators.

[0037] 2. By setting the locking structure 204, when the hammer 302 disassembles the refining vacuum tank, the lining of the refining vacuum tank will generate a reverse impact force on the hammer 302, the telescopic arm 301 and the traveling vehicle body 201. The locking structure 204 can offset the reverse impact force.

[0038] 3. When dismantling the refining vacuum tank, a large amount of dust will be generated. By setting up a power source component, a hydraulic power component, a telescopic hydraulic cylinder and a swing hydraulic cylinder, the operators can operate remotely away from the harsh working environment, which protects the safety of the operators to a certain extent and improves the efficiency of the operation.

[0039] In summary, this utility model effectively overcomes the various shortcomings of the prior art and has high industrial application value.
