Description

Technical Field

[0001] This invention relates to the field of track embedded parts construction technology, specifically to an installation method and auxiliary processing device for track embedded parts of a coke oven quenching car. Background Technology

[0002] In a certain project, the centerlines of coke ovens #5, #6, the coking integrated electrical room, #7, and #8 are all on a straight line. The machine-side coke pusher track is 720 meters long, and the coke-side quenching track is 756 meters long. Due to the long track length, the requirements for the flatness, firmness, and elevation control of the track embedded parts (designed to be continuous) during fabrication and installation are high. The aforementioned coke oven quenching track embedded parts typically consist of a top plate, web plate, bottom plate, and anchor bars. The top plate is 400mm wide, the bottom plate is 100mm wide, and the embedded part is 210mm high. During fabrication, steel plates are typically cut into top, web, and bottom plates and then assembled and welded. During installation, the embedded parts are typically fixed by welding the vertical anchor bars (Φ10) to the track foundation support beam itself, and elevation control is achieved using a gantry crane with a chain hoist and a level.

[0003] The above-mentioned embedded parts are made by cutting steel plates into top plates, web plates, and bottom plates (plates of the same length as the top plate) and assembling and welding them together. This method has the following defects: 1. The cutting and welding work is extensive and costly; 2. The embedded parts have large thermal deformation during welding and poor flatness after processing.

[0004] The current method of welding the vertical anchor bars of the track foundation connecting beam to the embedded parts has the following drawbacks: the small diameter (Φ10) of the vertical anchor bars makes them prone to bending and deformation, resulting in poor stability before the track beam concrete is poured. This also makes it difficult to securely fix the embedded parts and control their elevation and flatness. Furthermore, using a gantry crane with a chain hoist and a level for elevation and flatness control is slow and has large accuracy deviations. Therefore, we propose an installation method for the embedded parts of the coke oven quenching car track and an auxiliary processing device. Summary of the Invention

[0005] The purpose of this invention is to provide an installation method and auxiliary processing device for embedded parts in the track of a coke oven quenching car, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A method for installing embedded parts in the track of a coke oven quenching car, characterized by the following steps:

[0008] Step S1: Cut the finished H-beam in half along the center line of the web to obtain a semi-finished track embedded part with a top plate and a web.

[0009] Step S2: Weld strip steel plates at intervals to one end of the web of the semi-finished track embedded part 1 in step S1 relative to the top plate;

[0010] Step S3: Cut the threaded steel bar into long steel bar segments and bend them into L-shaped anchor bars. Weld multiple L-shaped anchor bars symmetrically at intervals along the long side of the semi-finished track embedded part one to the lower part of the top plate of the embedded part. Then weld two lifting lugs at both ends of the top plate of the semi-finished track embedded part one to obtain the finished track embedded part.

[0011] Step S4: Construct the connecting beam of the track bottom foundation pier. When pouring the concrete of the connecting beam of the track bottom foundation pier, insert multiple sets of Φ18 or Φ20 threaded steel bars on both sides of the center line of the beam as anchoring steel bars for welding and fixing the track embedded parts. After the concrete strength of the connecting beam of the track bottom foundation pier reaches the specification requirements, remove the formwork and backfill the earthwork. Then install the track beam steel bars to form the track beam steel bar skeleton. Use a crane to lift the finished track embedded parts from step S3 onto the track beam steel bar skeleton.

[0012] Step S5: Place two jacks at the bottom of the track beam as temporary supports for the adjustable height of the prefabricated track embedded parts. Use a level to measure the elevation and a spirit level to measure the flatness. First, place the jacks in the middle of the long side of a single prefabricated track embedded part and adjust the height of the jacks. After the elevation and flatness meet the requirements, spot weld the Φ18 or Φ20 anchoring steel bars to the prefabricated track embedded parts. Then adjust the position of the jacks and complete the spot welding of the Φ18 or Φ20 anchoring steel bars to the embedded parts of other parts of a single prefabricated track embedded part.

[0013] Step S6: After the elevation and flatness of the track embedded parts have been verified as qualified, the final welding of the Φ18 or Φ20 anchor steel bars and embedded parts is carried out. At this time, the installation of a single finished track embedded part is completed.

[0014] Step S7: Install track embedded parts in sections; after all the individual finished track embedded parts that make up a section of track are installed, weld the top plate gaps and web plate gaps between the embedded parts, and then set up the track beam formwork and pour concrete to complete the installation of all finished track embedded parts.

[0015] A further improvement is that, in step S5, if the top embedded part bends downward and deforms, a jack is used to slowly lift and correct the deformed part; if the top embedded part arches upward and deforms, a hammer is used to correct it.

[0016] An auxiliary processing device for embedded parts of a coke oven quenching car track, used to perform the above steps S1 and S2, includes:

[0017] A processing unit for cutting finished H-beams and welding the cut H-beams to strip steel plates, and a positioning unit for positioning the processing unit and the finished H-beams.

[0018] The processing unit includes two sets of symmetrically parallel mounting frames. One set of mounting frames has a guide rail frame 1 perpendicular to it in its inner cavity. A cutting device is slidably mounted on the guide rail frame 1. The outer end of the guide rail frame 1 has a telescopic device 1 that drives the cutting device to move along the guide rail frame 1. Both sets of mounting frames have a guide rail frame 2 parallel to the guide rail frame 1 located outside the guide rail frame 1. A welding device is slidably mounted on the guide rail frame 2. The outer end of the guide rail frame 2 has a telescopic device 2 that drives the welding device to move along the guide rail frame 2. Both ends of the mounting frame are equipped with an adjustable pulley structure 1 to allow the mounting frame to move within the finished H-beam.

[0019] The positioning part includes a cross-shaped frame. An adjustment mechanism is provided on the upper surface of the cross-shaped frame in a first direction. Both ends of the adjustment mechanism are connected to contact parts for contacting the long outer wall of the end flange of the H-beam or the long outer wall of the strip steel plate. The side wall of the contact part is connected to the side wall of the corresponding mounting frame through a telescopic rod. An adjustable pulley structure is provided on the upper surface of the cross-shaped frame in a second direction for contacting the upper surface of the H-beam or the upper surface of the strip steel plate. The first direction is parallel to the width direction of the H-beam to be processed, and the second direction is parallel to the length direction of the H-beam to be processed. The cross-shaped frame is connected to a driving mechanism, which is used to drive the cross-shaped frame to move along the length direction of the H-beam to be processed.

[0020] A further improvement is that the adjustable pulley structure includes movable plates that are symmetrically slidably disposed at the ends of the mounting frame. Each of the two sets of movable plates has a sliding roller connected to the inner wall of the finished H-beam steel to be processed via a roller frame and a rotating shaft on opposite sides.

[0021] In one set of adjustable pulley structures, two sets of movable plates on opposite sides are rotatably connected to an adjusting screw via bearings. The adjusting screw is vertically threaded into the mounting frame. The two sets of movable plates at corresponding positions in the two sets of adjustable pulley structures are connected by a linkage frame located inside the mounting frame.

[0022] A further improvement is that the adjustment mechanism includes a bidirectional screw that is rotatably mounted on the upper surface of the cross-shaped frame in a first direction via a bracket. Both ends of the outer wall of the bidirectional screw are threaded with connecting frames. Both ends of the upper surface of the cross-shaped frame in the first direction are provided with movable openings that extend along the first direction and allow the connecting frames to move. The connecting frames are T-shaped, and both ends of the connecting frames are connected to a contact portion.

[0023] A further improvement is that the contact part includes a positioning seat connected to the connecting frame. The positioning seat has a slider slidably mounted on the side facing the mounting frame via a vertical groove. An adjusting screw is threaded into the top of the positioning seat. The bottom end of the adjusting screw is rotatably connected to the slider. A positioning roller is detachably rotatably mounted on the bottom of the slider. An annular groove is formed on the outer circumference of the positioning roller. The axial height of the annular groove is adapted to the thickness of the flange or strip steel plate at the end of the finished H-beam.

[0024] A further improvement is that the adjustable pulley structure two includes movable frames that are slidably sleeved on both ends of the upper surface of the cross-shaped frame in the second direction. The bottom rotating shaft of the movable frame is connected to a contact roller that contacts the end wing plate or strip steel plate of the finished H-beam. The two sets of movable frames are connected by a connecting frame. The connecting frame is located above the adjustment mechanism one. The connecting frame is threaded onto the outer wall of the adjustment screw three. The bottom of the adjustment screw three is rotatably connected to the upper surface of the cross-shaped frame.

[0025] A further improvement is that the drive mechanism includes a pull rope connected to the cross-shaped frame, the other end of which is connected to a winch device, which is mounted on the insert.

[0026] Compared with the prior art, the beneficial effects of the present invention are:

[0027] 1) This invention uses H-beams to cut into semi-finished products, namely the top plate and web plate of the track embedded parts, which can avoid deformation of the top plate caused by welding the top plate and web plate of the embedded parts, and at the same time reduce the amount of cutting and welding work and reduce processing costs.

[0028] 2) The bottom plate of the track embedded part of the present invention is made of short plates for intermittent welding, which can reduce the deformation of the embedded part during welding; when the top plate of the embedded part is deformed, the web plate at the corresponding position of the intermittent part bottom plate can be cut to adjust the elevation and flatness of the top plate of the embedded part.

[0029] 3) The L-shaped anchor bars of the track embedded parts of this invention adopt a skip welding method, which can reduce the welding deformation of the embedded parts;

[0030] 4) The track foundation connecting beam of this invention has a pre-set Φ18 or Φ20 anchoring steel bar, which has a large diameter and high strength. This can avoid the difficulty of installing the embedded parts due to the bending and deformation of the anchoring steel bar, and can ensure that the embedded parts are installed and fixed firmly.

[0031] 5) This invention utilizes jacks and other auxiliary tools for the installation of track embedded parts, which can accurately adjust the elevation and flatness of the track embedded part top plate, thus improving efficiency; 6) The auxiliary processing device used in this invention positions the processing unit on the finished H-beam through the positioning unit. The driving mechanism can drive the cross-shaped frame and the installation frame to move along the long side of the finished H-beam. During the movement, the finished H-beam can be cut by cutting equipment or welding equipment, and the finished H-beam can be welded to the strip steel plate after cutting. This greatly reduces the efficiency and quality of manual cutting and welding. At the same time, the positioning unit not only ensures that the processing unit can move stably along the finished H-beam, but also positions one end of the finished H-beam during cutting and positions the strip steel plate during welding, further improving the efficiency and quality of cutting and welding.

[0039] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0040] Example 1

[0041] Please see the appendix Figure 1 A method for installing embedded parts in the track of a coke oven quenching car, specifically including the following steps:

[0042] Step S1: Cut a 400mm×400mm H-beam (12 meters long) in half along the center line of the web. The H-beam is existing technology. It includes a web and integrated flanges at both ends. After cutting, a semi-finished track embedding part one with a top plate (i.e., a flange at one end) and a web is obtained. The semi-finished track embedding part one is attached... Figure 1 The middle part is A. Through this step, the web plate and top plate of the track embedded part do not need to be welded on site, thus avoiding deformation caused by welding the top plate and web plate.

[0043] Step S2: In step S1, strip steel plates are welded at intervals to one end of the web of the semi-finished track embedded part 1 relative to the top plate. The strip steel plates are obtained by cutting 2-meter wide and 14mm thick steel plates (9.6-12 meters long) into 2-meter long and 100mm wide pieces. The strip steel plates are attached to... Figure 1 B is welded at 10mm intervals to the lower part of the web of the semi-finished embedded part to form the bottom plate of the embedded part;

[0044] Step S3: Cut the Φ12 threaded steel bar into 500mm long steel bar segments and bend them into 400mm×100mm L-shaped anchor bars. Weld multiple L-shaped anchor bars symmetrically at 200mm intervals (symmetrical spacing 300mm) along the long side of the semi-finished track embedded part one to the lower part of the top plate of the embedded part. When welding, use the skip welding method. First, weld along the length of the embedded part at 1-meter intervals, and then weld from the middle part to both ends at multiples of 200mm intervals to reduce the welding deformation of the top plate of the embedded part. Then, weld two lifting lugs about 2 meters away from both ends on the top plate of the semi-finished track embedded part one to obtain the finished track embedded part. The lifting lugs are for use by crane to lift and position during installation.

[0045] Step S4: Construct the connecting beam of the bottom foundation of the track. When the concrete of the connecting beam of the bottom foundation of the track is poured, insert 400mm long Φ18 (20) threaded steel bars at a spacing of 300mm on both sides of the center line of the beam and at a length interval of 1.5m (200mm inserted into the concrete and 200mm exposed outside) as anchoring steel bars for welding and fixing the track embedded parts. The Φ18 (20) anchoring steel bars can be made using the leftover steel bars on site. After the concrete strength of the connecting beam of the bottom foundation of the track reaches the specification requirements, remove the formwork and backfill the earthwork. Then install the track beam steel bars to form the track beam steel bar skeleton. Use a crane to lift the finished track embedded parts of step S3 onto the track beam steel bar skeleton.

[0046] S5: Place two jacks at the bottom of the track beam as temporary supports for the adjustable height of the finished track embedded parts. Use a level to measure the elevation and a spirit level to measure the flatness. First, place the jacks in the middle of the long side of a single finished track embedded part and adjust the height of the jacks. After the elevation and flatness meet the requirements, spot weld the Φ18(20) anchor steel bars to the embedded parts and then adjust the position of the jacks to complete the spot welding of the Φ18(20) anchor steel bars to the embedded parts in other parts of the single finished track embedded parts.

[0047] In step S5, if the top embedded part bends downward and deforms, use a jack to slowly lift and correct the deformed part; if the top embedded part arches upward and deforms, use a hammer to correct it. At the same time, when correcting the deformation of the top plate, make a 5mm vertical cut at the position of the web plate corresponding to the 10mm gap in the bottom plate of the adjacent embedded part, so as to adjust the deformation of the top plate of the embedded part.

[0048] Step S6: After the elevation and flatness of the track embedded parts are verified to be qualified, the final welding of the Φ18(20) anchor steel bars and embedded parts is carried out. At this time, the installation of a single finished track embedded part is completed.

[0049] Step S6: Due to the long track, the track embedded parts are installed in sections. After all the individual finished track embedded parts that make up the track section are installed, the gaps between the embedded parts in the top plate and the gaps in the web plate are welded (partial welding is sufficient). Then, the track beam formwork is erected and the concrete is poured to complete the installation of all finished track embedded parts.

[0050] It should be noted that expansion joints are provided between adjacent sections of track beams.

[0051] Please see the appendix Figure 2 - Appendix Figure 7 An auxiliary processing device for the track embedded parts of a coke oven quenching car, used to implement the above steps S1 and S2, includes: a processing part 1 for cutting the finished H-beam steel to be processed and welding the cut finished H-beam steel to the strip steel plate, and a positioning part 2 for positioning the processing part 1 and the finished H-beam steel to be processed.

[0052] The processing unit 1 includes two sets of symmetrically parallel mounting frames 11, which extend along the long side of the finished H-beam steel to be processed.

[0053] One of the mounting frames 11 has a guide rail frame 12 perpendicular to it in its inner cavity. A cutting device 13 is slidably mounted on the guide rail frame 12. The cutting device 13 is a prior art device, such as a rotating device and a cutting disc. The outer end of the guide rail frame 12 is provided with a telescopic device 14 that drives the cutting device 13 to move along the guide rail frame 12. The position of the cutting device 13 can be adjusted by the telescopic device 14.

[0054] Both sets of mounting frames 11 are equipped with guide rail frames 19 parallel to guide rail frames 12, located inside and outside the guide rail frame 12. Welding equipment 110 is slidably mounted on guide rail frame 19. Welding equipment 110 is a prior art device, such as a welding torch. The outer end of guide rail frame 19 is equipped with telescopic device 111 that drives welding equipment 110 to move along guide rail frame 19. The position of welding equipment 110 can be adjusted by telescopic device 111. Both ends of mounting frame 11 are equipped with adjustable pulley structure 1 to allow mounting frame 11 to move within the H-beam.

[0055] The positioning part 2 includes a cross-shaped frame 21. An adjustment mechanism 1 is provided on the upper surface of the cross-shaped frame 21 in a first direction. Both ends of the adjustment mechanism 1 are connected to contact parts for contacting the long outer wall of the end flange of the finished H-beam or the long outer wall of the strip steel plate. Specifically, during cutting, the contact parts are used to contact the long outer wall of the upper flange of the finished H-beam to ensure the stability of the finished H-beam during the cutting process. During welding, the contact parts are used to contact the long outer wall of the strip steel plate to position the strip steel plate and ensure stable welding between the strip steel plate and the web plate. The sidewall of the contact part is connected to the sidewall of the corresponding mounting frame 11 via a telescopic rod 25. This method allows the contact part to move with the mounting frame 11 inside the H-beam while being adjusted relative to the mounting frame 11 via an adjustment mechanism to fix the wing plate and strip steel plate at one end of the H-beam. An adjustable pulley structure 2 is provided on the second direction of the upper surface of the cross-shaped frame 21 for contacting the upper surface of the H-beam or the upper surface of the strip steel plate, so as to ensure that the auxiliary processing device moves stably along the H-beam to perform cutting and welding operations.

[0056] It should be noted that the first direction is parallel to the width direction of the finished H-beam to be processed, and the second direction is parallel to the length direction of the finished H-beam to be processed.

[0057] The cross-shaped frame 21 is connected to a drive mechanism, which is used to drive the cross-shaped frame 21 to move along the length of the finished H-beam steel product to be processed.

[0058] As a preferred embodiment, the adjustable pulley structure includes movable plates 15 symmetrically slidably disposed at the ends of the mounting frame 11. Each of the two sets of movable plates 15 has a sliding roller connected to the inner wall of the finished H-beam through a rotating shaft of a roller frame 16. Specifically, during cutting, the sliding rollers on the two sets of movable plates 15 contact the outer wall of the opposite side of the flanges at both ends of the finished H-beam. During welding, the sliding rollers on one set of movable plates 15 contact the inner outer wall of one flange of the finished H-beam, and the sliding rollers on the other set of movable plates 15 contact the inner wall of the strip steel plate.

[0059] In one set of adjustable pulley structures, the two sets of movable plates 15 on opposite sides are rotatably connected to adjusting screws 17 via bearings. The adjusting screws 17 are vertically threaded into the mounting frame 11. The outer end of the adjusting screws 17 is provided with a turntable for the user to rotate. By rotating the adjusting screws 17, the movable plates 15 can be moved, thereby adjusting the position of the sliding rollers. The two sets of movable plates 15 in corresponding positions in the two sets of adjustable pulley structures are connected by a linkage frame 18, that is, the movable plates 15 at the top of both ends are connected by a linkage frame 18, and the movable plates 15 at the bottom of both ends are connected by a linkage frame 18. The linkage frame 18 is located inside the mounting frame 11.

[0060] Preferably, the adjustment mechanism of this embodiment includes a bidirectional screw 22 rotatably mounted on the upper surface of the cross-shaped frame 21 in a first direction via a bracket. Both ends of the outer wall of the bidirectional screw 22 are threaded with connecting frames 23. Both ends of the upper surface of the cross-shaped frame 21 in the first direction are provided with movable openings extending in the first direction for the connecting frames 23 to move. The connecting frames 23 are T-shaped, and both ends of the connecting frames 23 are connected to a contact portion. One end of the bidirectional screw 22 is provided with a turntable for the user to rotate. Rotation of the bidirectional screw 22 can drive the two sets of connecting frames 23 to move closer or further apart, thereby adjusting the position of the contact portion. Specifically, the contact portions at both ends of the connecting frames 23 are located on both sides of the extension direction of the guide rail frame 12.

[0061] Preferably, the contact part in this embodiment includes a positioning seat 24 connected to the connecting frame 23. Specifically, the telescopic rod 25 connects the positioning seat 24 and the mounting frame 11. The positioning seat 24 has a slider slidably mounted on the side facing the mounting frame 11 through a vertical groove. An adjusting screw 26 is threaded into the top of the positioning seat 24. One end of the adjusting screw 26 has a turntable for the user to rotate. The bottom end of the adjusting screw 26 is rotatably connected to the slider. A positioning roller 27 is detachably rotatably mounted on the bottom of the slider. An annular groove is opened on the outer circumference of the positioning roller 27. The axial height of the annular groove is adapted to the thickness of the flange or strip steel plate at the end of the H-beam finished product. The positioning roller 27 is locked onto the outer edge of the flange or strip steel plate of the H-beam finished product through the annular groove, thereby fixing the flange and strip steel plate at the end of the H-beam finished product and ensuring the stability of the cutting of the H-beam finished product and the welding of the H-beam finished product to the strip steel plate.

[0062] As a preferred embodiment, the adjustable pulley structure two includes movable frames 28 that are slidably sleeved on both ends of the upper surface of the cross-shaped frame 21 in the second direction. The vertical cross section of the movable frame 28 is U-shaped. The bottom rotating shaft of the movable frame 28 is connected to a contact roller 210 that contacts the end wing plate or strip steel plate of the finished H-beam. The two sets of movable frames 28 are connected together by a connecting frame 23. The connecting frame 23 is located above the first adjustment mechanism. The connecting frame 23 is threaded onto the outer wall of the third adjustment screw 29. The bottom of the third adjustment screw 29 is rotatably connected to the upper surface of the cross-shaped frame 21. One end of the third adjustment screw 29 is provided with a turntable for the user to rotate. By rotating the third adjustment screw 29, the connecting frame 23 can be driven to move the movable frame 28 up or down so that the contact roller 210 contacts the end wing plate or strip steel plate of the finished H-beam.

[0063] Preferably, the driving mechanism in this embodiment includes a pull rope 211 connected to the cross-shaped frame 21, and the other end of the pull rope 211 is connected to a winch device, which is mounted on the insert 212. The winch device is prior art. The insert 212 is, for example, an insertion cone. By placing the insert 212 at one end of the finished H-beam to be processed, the pull rope 211 is wound up by the winch device, which can pull the cross-shaped frame 21, the mounting frame 11, and other structures from the other end of the finished H-beam along the length of the finished H-beam. During the movement, cutting and welding work can be performed by the cutting equipment 13 and the welding equipment 110.

[0064] The working principle of this auxiliary processing device is as follows:

[0065] The finished H-beam to be processed is placed in the designated position, and the two sets of mounting frames 11 enter the inner cavity of the finished H-beam from one end. Adjust the adjustable pulley structure one according to the cutting position and make the adjustable pulley structure one fit against the inner wall of the finished H-beam. Adjust the contact part through the adjustment mechanism one so that the contact parts at both ends contact the outer wall of the long side of the top flange of the finished H-beam. Then, the adjustable pulley structure two contacts the upper surface of the top flange of the finished H-beam. Subsequently, the cross-shaped frame 21 is driven by the drive mechanism to move along the finished H-beam. During the movement, the cutting device 13 is turned on and the position of the cutting device 13 is adjusted by the telescopic device one 14 until the cutting device 13 cuts the finished H-beam in two from the center line of the web.

[0066] The strip steel plate is placed on the web of a pre-cut H-beam. The contact portion is then adjusted using an adjusting mechanism to ensure contact between the two ends and the strip steel plate. The position of the welding device 110 is adjusted by opening the telescopic device 111, aligning the welding device 110 with the connection point between the strip steel plate and the web. The drive mechanism then moves the cross-shaped frame 21 along the H-beam. During this movement, the welding device 110 is opened to weld the connection point between the strip steel plate and the web. After welding, the auxiliary processing device is removed for the next step. Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
