Description

Technical Field

[0001] The present invention belongs to the technical field of the installation of plug bricks, and more specifically, relates to an installation device and a construction method for plug bricks of drying holes at the top of a coke oven carbonization chamber. Background Technique

[0002] When building the overhead area at the top of the coke oven carbonization chamber, drying holes for oven drying are left, which are located at the coal charging hole and the overhead part of the oven head on the machine side and the coke side respectively. After the coke oven oven drying is completed and the small oven drying stoves are removed, the drying holes need to be blocked. Generally, plug bricks are dipped in refractory mud to prevent leakage. There are generally 6 drying holes in the overhead area at the top of the coke oven carbonization chamber, and the vertical distance from the drying holes to the construction platform is 7 meters. In order to prevent the temperature in the carbonization chamber from dropping too fast, the plug bricks need to be installed quickly.

[0003] During the operation of the traditional installation method, the operator needs to stand on the pusher car or the coke guide car and use a special tool, which is a steel pipe with a length of 9 meters and a diameter of 4 minutes, and a steel bar hook is welded at the front end. By hooking the square reserved hole at the tail end of the plug brick with the steel bar hook and dipping it in the mud, the operator needs to lift this steel pipe obliquely, firmly hold the other end, so as to accurately install the plug brick into the drying hole. However, this method requires the construction personnel to directly face the high-temperature working environment in the carbonization chamber, and they must wear thick heat-insulating clothes and protective masks (which greatly limits the line of sight), hold a tool weighing nearly 20 catties, and accurately align the drying hole with a diameter of only 70 mm for installation at an oblique distance of up to 9 meters.

[0004] This method not only puts extremely high requirements on the installation accuracy, but also consumes a large amount of human resources. In order to complete this complex and delicate task, usually experienced technicians take turns to operate to reduce fatigue and improve the success rate. In addition, due to the long installation process, the temperature in the carbonization chamber may drop significantly, which will affect the normal production progress of the coke oven. Therefore, although this traditional installation method can meet the basic requirements to a certain extent, there are obvious deficiencies in terms of efficiency, safety and accuracy, and it is urgent to find a more efficient, safe and accurate alternative solution. Summary of the Invention

[0005] In view of the above deficiencies or improvement requirements of the prior art, the present invention provides an installation device and construction method for a plug brick of a drying hole at the top of a coke oven carbonization chamber. The plug brick is firmly clamped by the clamping unit, the plug brick is accurately aligned with the drying hole by means of the observation unit, and the plug brick is efficiently and firmly installed into the drying hole by using the pushing unit, significantly improving the installation accuracy and efficiency of the plug brick, ensuring the installation quality and sealing performance. At the same time, the labor intensity is reduced, the dependence on the physical strength and experience of construction workers is reduced, making the installation work easier and more controllable. Moreover, the operation risk is reduced, avoiding potential safety hazards that may be brought by long-term operation of construction workers in a high-temperature environment, and ensuring the personal safety of construction workers.

[0042] S6: Repeat steps S1 to S5 to complete the construction of all drying holes.

[0043] Generally speaking, compared with the prior art, the above technical solution conceived by the present invention can achieve the following beneficial effects:

[0044] 1. The installation device of the present invention firmly clamps the stopper brick through the clamping unit, uses the observation unit to assist in accurately aligning the stopper brick with the drying hole, and adopts the push unit to efficiently and firmly install the stopper brick into the drying hole, significantly improving the installation accuracy and efficiency of the stopper brick, ensuring the installation quality and tightness. At the same time, it reduces the labor intensity, reduces the dependence on the physical strength and experience of construction workers, makes the installation work easier and more controllable, and reduces the operation risk, avoiding potential safety hazards that may be brought by construction workers working in a high-temperature environment for a long time, and ensuring the personal safety of construction workers.

[0045] 2. The installation device of the present invention, through the multi-stage structure of the hollow horizontal tube, fully considers the assembly requirements of the push assembly. At the same time, the oval design of the support plate not only optimizes the cooperation effect with the clamping assembly, but also effectively reduces its own weight. In addition, on the premise of ensuring that the support unit has the necessary structural strength, this design scheme takes into account the stable assembly and use efficiency of other components, thus ensuring the smooth progress of the construction process and further improving the practicality and reliability of the entire device.

[0046] 3. The installation device of the present invention, through the coordinated action of the clamping switch and the two reverse springs, enables the clamping force of the plug brick to be adjusted more gently, thereby avoiding installation deviations caused by over-tight or over-loose clamping, and effectively improving the accuracy of installing the plug brick. Secondly, through the rotational connection design of the first connecting rod and the clamping block, the plug brick can swing left and right, so that the position and attitude can be adjusted in real time during the operation process, and the drying hole can be advanced in the best attitude, further improving the installation accuracy.

[0047] 4. The installation device of the present invention stretches the third steel strand through the pushing switch, thereby compressing the pushing spring. When the plug brick is aligned with the drying hole, the self-locking state of the pushing switch is released, and the pushing spring can release energy in time to push the pushing rod to impact the plug brick, so as to achieve rapid and accurate installation of the plug brick through the above design, ensuring that it is firmly embedded in the drying hole. At the same time, through multiple rounds of stretching and releasing of the pushing switch, the operator can flexibly control the pushing force and timing, thus avoiding installation failures caused by excessive or insufficient thrust; in addition, the design of this method simplifies the operation process, reduces the dependence on manual force, and improves the safety and efficiency of installation.

[0059] Embodiment 1

[0060] As Figures 1 to 8As shown in the figure, Embodiment 1 of the present invention provides a plug brick installation device for the top of the coke oven carbonization chamber, including: a support unit 1, a clamping unit 2, a pushing unit 3 and an observation unit 4; the support unit 1 includes: a hollow inclined pipe 11, a hollow horizontal pipe 12 connected to the upper end of the hollow inclined pipe 11, and a support plate 13 connected to the hollow horizontal pipe 12; the clamping unit 2 includes: a clamping switch 21 arranged at the lower end outside the hollow inclined pipe 11, and a clamping assembly 22 connected to the clamping switch 21 and arranged on the front side of the support plate 13; the pushing unit 3 includes: a pushing switch 31 arranged at the lower end outside the hollow inclined pipe 11, and a pushing assembly 32 connected to the pushing switch 31 and having one end passing through the support plate 13; the observation unit 4 is used to assist in observing the installation process of the plug brick 5. During use, the plug brick 5 is firmly clamped by the clamping unit 2, the plug brick 5 is accurately aligned with the drying hole by using the observation unit 4, and the plug brick 5 is efficiently and firmly installed into the drying hole by using the pushing unit 3, significantly improving the installation accuracy and installation efficiency of the plug brick 5, ensuring the installation quality and sealing performance. At the same time, the labor intensity is reduced, the dependence on the physical strength and experience of the construction personnel is reduced, making the installation work easier and more controllable. Moreover, the operation risk is reduced, avoiding potential safety hazards that may be brought about by the construction personnel working in a high-temperature environment for a long time, and ensuring the personal safety of the construction personnel.

[0061] Further, as Figures 1 to 3 , Figures 6 to 7 described, the support unit 1 is used to stably support other components. In this support unit 1, the hollow horizontal pipe 12 includes: an outer pipe 121 connected to the hollow inclined pipe 11, an inner pipe 122 connected to the middle part of the rear side of the support plate 13, and a connecting piece 123 arranged between the outer pipe 121 and the inner pipe 122.

[0062] The inner diameter of the outer pipe 121 is larger than the outer diameter of the inner pipe 122; the connecting piece 123 is integrally formed as a circular plate and two connecting blocks symmetrically arranged on the outer edge of the circular plate. The circular plate is connected to one end of the inner pipe 122 and its outer diameter is the same as the outer diameter of the inner pipe 122. The two connecting blocks are respectively connected to one end of the outer pipe 121; symmetrically arranged chutes 1221 adapted to the pushing assembly 32 are provided on the inner pipe 122; the support plate 13 is an elliptical plate, and a through hole adapted to the inner diameter of the inner pipe 122 is provided in the middle thereof, and the long axis direction thereof is the vertical direction.

[0063] In an optional embodiment, the included angle between the hollow inclined pipe 11 and the outer pipe 121 is 120 degrees to 150 degrees, and a rib plate is provided at this included angle to adapt to different construction requirements and ensure the structural safety.

[0064] In an alternative embodiment, the support unit 1 further includes at least two grips 14, which are respectively arranged outside the hollow inclined tube 11, and an anti-slip grip is sleeved on the outside of each grip 14 to enhance the stability and comfort of the operator during gripping, thereby improving the operation convenience and safety of the entire installation device.

[0065] In an alternative embodiment, the support unit further includes a support frame 15, and the support frame 15 includes: a support base 151, a support rod 152 and an arc-shaped support plate 153; the support base 151 is an overall solid metal circular plate, which is arranged on the construction tabletop and is connected to the support rod 152 at the middle of the upper end; the arc-shaped support plate 153 is arranged at the upper end of the support rod 152 and a rubber pad is further arranged at the upper end thereof. It should be noted that by placing the hollow inclined tube 11 on the upper end of the arc-shaped support plate 153, at the same time, the position of the support plate 13 is adjusted by using the lever principle in cooperation with the grip 14, and the support base 151 of the solid metal circular plate ensures no shaking during the installation process, thereby effectively reducing the construction difficulty and improving the construction efficiency. It can be understood that the method of using the solid metal circular plate is considered for the case of variable construction planes, thereby improving the adaptability of the support frame 15. And when using this installation device, usually the operator adopts a stance with one foot in front of the other. At this time, generally, the front foot can be stepped on the support base 151 to further enhance the construction stability and accuracy.

[0066] It should be noted that through the multi-stage structure of the hollow horizontal tube 12, the assembly requirements of the jacking assembly 32 are fully considered. At the same time, the oval design of the support plate 13 not only optimizes the cooperation effect with the clamping assembly, but also effectively reduces its own weight. In addition, on the premise of ensuring that the support unit 1 has the necessary structural strength, this design scheme takes into account the stable assembly and use efficiency of other components, thereby ensuring the smooth progress of the construction process and further improving the practicability and reliability of the entire device.

[0067] Furthermore, as Figure 1 、 Figures 3 to 6As described above, the clamping unit 2 is used to firmly clamp the plug brick 5. In the clamping unit, the clamping assembly 22 includes: a fixed vertical rod 221, a fixed block 222, a reversing block 223, a transmission block 224, a first connecting rod 225 and a clamping block 226; the two fixed vertical rods 221 are symmetrically arranged on the long axis of the support plate 13 with the center of the support plate 13 as the center; the fixed block 222 is arranged on one side of the support plate 13 and on its short axis; the reversing block 223 is an arc-shaped block as a whole, and is rotatably connected to the fixed block 222 through a central through hole and a bolt, and its lower end is connected to one end of the lower transmission block 224 through a fastening bolt and a second steel strand 2231; the two fixed vertical rods 221, the two transmission blocks 224, the two first connecting rods 225 and the two clamping blocks 226 are respectively arranged symmetrically with the reversing block 223 as the mirror image and are connected through the same connection mechanism; wherein, the transmission block 224 is in a herringbone shape as a whole, one end is provided with a through hole adapted to the first connecting rod 225, and one end is rotatably connected to the fixed vertical rod 221 through a reverse shaft 2241 and a reverse spring 2211 arranged in the fixed vertical rod 221. At the same time, the reverse shaft 2241 is in interference fit with the transmission block 224, and the reverse spring 2211 is sleeved outside the reverse shaft 2241 and both ends are respectively connected to the inner wall of the fixed vertical rod 221 and the shaft rod of the reverse shaft 2241 penetrating into the fixed vertical rod 221; the first connecting rod 225 is connected to one end of the transmission block 224 through interference fit, and the other end is provided with a vertical through hole; the clamping block 226 includes: a second connecting rod 2261 rotatably connected to one end of the first connecting rod 225, and a clamping plate 2262 arranged at the other end of the second connecting rod 2261; the connection area between the second connecting rod 2261 and the first connecting rod 225 is provided with an external thread, and is kept rotatably connected to the first connecting rod 225 through two nuts sleeved outside the second connecting rod 2261 and respectively contacting the upper end and the lower end of the first connecting rod 225; the clamping switch 21 is a bicycle handbrake, and is respectively connected to the upper end of the reversing block 223 and the upper transmission block 224 through a first steel strand 211, that is, one end of the first steel strand 211 is connected to one end of the upper transmission block 224, and the other end is connected to one end of the reversing block 223 through a fastening bolt and then passes through the support plate 13, penetrates into the outer tube 121 and the hollow inclined tube 11 in sequence, and passes through the hollow inclined tube 11 to be connected to the clamping switch 21.

[0068] In an alternative embodiment, a washer made of polytetrafluoroethylene is provided between the nut and the first connecting rod 225 to reduce the friction between the nut and the first connecting rod 225 and significantly improve the service life while ensuring that the second connecting rod 2261 does not slide up and down with the first connecting rod 225 during operation.

[0069] In an alternative embodiment, the clamping plate 2262 includes a flat plate or an arc plate to adapt to different types of stopper bricks, thereby improving the applicability of the device.

[0070] It can be understood that when the clamping assembly 22 does not clamp the stopper brick 5, the clamping switch 21 is in a released state. The upper transmission block 224 moves clockwise around the corresponding reverse rotation shaft 2241 under the action of the reverse spring 2211, while the lower transmission block 224 moves counterclockwise around the corresponding reverse rotation shaft 2241 under the action of the reverse spring 2211, so that the upper and lower clamping blocks 226 move away from the clamping area; when it is necessary for the clamping assembly 22 to clamp the stopper brick 5, the stopper brick 5 is placed in the clamping area, and the clamping switch 21 is tightly held. The upper transmission block 224 moves counterclockwise around the corresponding reverse rotation shaft 2241 under the combined action of the first steel strand 211 and the reverse spring 2211, while the lower transmission block 224 still moves counterclockwise around the corresponding reverse rotation shaft 2241 under the action of the reverse spring 2211. However, since the descending distance of the upper clamping block 226 is greater than that of the lower clamping block 226, and at the same time, due to the length limitation of the steel strand between the reversing block 223 and the lower transmission block 224, at this time, the two clamping blocks 226 can stably clamp the stopper brick 5.

[0071] It should be noted that through the coordinated action of the clamping switch 21 and the two reverse springs 2211, the clamping force of the stopper brick can be adjusted more gently, thereby avoiding installation deviation caused by over-tightening or over-loosening, and effectively improving the accuracy of installing the stopper brick. Secondly, through the rotational connection design of the first connecting rod 225 and the clamping block 226, the stopper brick 5 can swing left and right, so that the position and attitude can be adjusted in real time during the operation process, and the drying hole can be advanced in the best attitude, further improving the installation accuracy.

[0072] Furthermore, as Figure 1 、 Figure 2 and Figure 6As described above, the pushing unit 3 is used to firmly install the stopper brick 5 into the drying hole. In this pushing unit 3, the pushing assembly 32 includes: a pushing spring 321, a stretching sheet 322, a pushing rod 323, and a third steel strand 324; the pushing spring 321 is arranged inside the inner tube 122, and its two ends are respectively connected to the connecting sheet 123 and the stretching sheet 322; the stretching sheet 322 is integrally formed as a circular plate and two connecting blocks symmetrically arranged at the outer edge of the circular plate. The circular plate is arranged inside the inner tube 122, and the two connecting blocks are adapted to the two sliding grooves 1221 and extend outside the inner tube 122 from the sliding grooves 1221; one end of the pushing rod 323 is connected to the stretching sheet 322, and the other end passes through the support plate 13 and contacts the stopper brick 5; one end of the third steel strand 324 is connected to the pushing switch 31, and the other end penetrates into the hollow inclined tube 11 and bifurcates inside the outer tube 121 and is respectively connected to the two connecting blocks of the stretching sheet 322; the pushing switch 31 is a manual winch, and the manual winch is provided with a self-locking component.

[0073] It can be understood that the connecting blocks on the connecting sheet 123 and the connecting blocks on the stretching sheet 322 are not aligned to ensure that the third steel strand 324 does not interfere with the connecting blocks of the connecting sheet 123 when penetrating into the outer tube 121.

[0074] Preferably, the model of the pushing switch 31 is 1200LB.

[0075] In an alternative embodiment, the distance between the bifurcation of the third steel strand 324 and the connecting sheet 123 is at least 1.5 times the length of the pushing spring 321, so as to avoid the interference of the connecting sheet 123 and ensure that the pushing spring 321 can deform normally.

[0076] In an alternative embodiment, a circular plate is provided at one end of the pushing rod 323 close to the stopper brick 5 to reduce the pressure of the pushing rod 323 on the stopper brick 5 and ensure the structural stability of the stopper brick 5.

[0077] It should be noted that by stretching the third steel strand 324 through the pushing switch 31, the pushing spring 321 is compressed. When the stopper brick 5 is aligned with the drying hole, the self-locking state of the pushing switch 31 is released, and the pushing spring 321 can release energy in time to push the pushing rod 323 to impact the stopper brick 5. Thus, through the above design, the quick and precise installation of the stopper brick 5 can be realized, ensuring that it is firmly embedded in the drying hole. At the same time, through multiple rounds of stretching and releasing of the pushing switch 31, the operator can flexibly control the pushing force and timing, thereby avoiding installation failures caused by excessive or insufficient thrust; in addition, the design of this method simplifies the operation process, reduces the dependence on manual strength, and improves the safety and efficiency of installation.

[0078] Further, as Figure 1 , Figure 3 and Figure 8 described, the observation unit 4 is used to assist in observing the installation process of the plug brick 5. The observation unit 4 includes: a display 41 provided at the lower end of the outer side of the hollow inclined tube 11, and a camera 42 connected to the display 41 and provided on one side of the support plate 13; the camera 42 is provided at the edge of the support plate 13 through a mounting seat and is provided on the horizontal plane of the long axis of the support plate 13, and the included angle between its optical axis and the plug brick 5 is 30 degrees to 60 degrees; the display 41 is internally provided with a rechargeable lithium battery, and is communicatively connected and electrically connected to the camera 42 by a wired method. It can be understood that a corresponding switch is provided on the display 41 to control the operation of the observation unit.

[0079] In an alternative embodiment, the camera 42 is provided at the rear side of the support plate 13 through a mounting seat, a through hole with quartz glass is provided on the support plate 13 in front of the lens thereof, and the included angle between the optical axis of the camera and the plug brick 5 is 30 degrees to 60 degrees, so as to reduce the possible damage to the camera 42 caused by high temperature under the condition of meeting the observation field of view.

[0080] It should be noted that through the design of the position and posture of the camera 42, the field of view range and shooting angle of the camera are greatly improved, so that it can better capture the real-time state of the plug brick 5 during the installation process, thereby ensuring that in a high-temperature environment, the operator can clearly observe the docking situation between the plug brick and the drying hole, improving the accuracy and safety of the installation; secondly, the communication connection between the display 41 and the camera 42 is carried out by a wired method to ensure the stability and real-time nature of data transmission, so that the operator can immediately obtain the image information during the installation process.

[0081] Embodiment 2

[0082] As Figure 9 shown, on the basis of Embodiment 1, Embodiment 2 of the present invention provides a construction method for an installation device for a plug brick at the top of a coke oven carbonization chamber, including the following steps:

[0083] S1: Check that the installation device is operating normally, compress the push spring 321 through the push switch 31 and turn on the self-locking function, so that the push rod 323 retracts to mount the plug brick 5;

[0084] S2: Release the clamping switch 21, place the plug brick 5 between the two clamping blocks 226, and clamp the plug brick 5 by holding the clamping switch 21 tightly;

[0085] S3: Using the image information transmitted by the camera 42 in the display 41, adjust the plug brick 5 to be perpendicular to the coke oven wall and close to the drying hole by means of the grip 14 and the hollow inclined tube 11;

[0086] S4: When the plug brick 5 is not completely aligned with the drying hole in the horizontal direction, push the front end of the plug brick 5 into the drying hole. By utilizing the rotational connection relationship between the clamping block 226 and the first connecting rod 225, and by releasing the self-locking function of the push switch 31, and using the expansion and contraction of the push spring 321, the push rod 323 is used to push the rear end part of the plug brick 5 into the drying hole;

[0087] S5: When the plug brick 5 is not completely aligned with the drying hole in the vertical direction, adjust the height of the support plate 13 by means of the grip 14 and the hollow inclined tube 11 until the plug brick 5 is aligned with the drying hole. Then, by releasing the self-locking function of the push switch 31, and using the expansion and contraction of the push spring 321, the push rod 323 is used to push the rear end part of the plug brick 5 into the drying hole;

[0088] S6: Repeat steps S1 to S5 to complete the construction of all drying holes.

[0089] It can be understood that the incomplete alignment of the plug brick 5 with the drying hole in the horizontal direction in step S4 means that the axis of the plug brick 5 is not aligned with the axis of the drying hole in the horizontal direction; the incomplete alignment of the plug brick 5 with the drying hole in the vertical direction in step S5 means that the axis of the plug brick 5 is not aligned with the axis of the drying hole in the vertical direction.

[0090] Other technical features are the same as those in Embodiment 1 and can achieve the same technical effects, which will not be elaborated one by one here.

[0091] It should be noted that if there are directional indications (such as up, down, left, right, front, back...) involved in the embodiments of the present invention, then such directional indications are only used to explain the relative positional relationship and movement conditions between components in a certain specific posture (as shown in the drawings). If this specific posture changes, then the directional indications will also change accordingly.

[0092] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present invention, then such descriptions of "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one such feature. In addition, the technical solutions between various embodiments can be combined with each other, but it must be based on the fact that those of ordinary skill in the art can implement them. When the combination of technical solutions results in contradictions or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0093] In the present invention, the terms "comprising", "including" or any other variants thereof are intended to cover non-exclusive inclusion, such that a process, method, article or device comprising a series of elements not only includes those elements but also other elements not expressly listed, or further includes elements inherent to such process, method, article or device. Without further limitation, an element defined by the statement "comprising..." does not exclude the presence of additional identical elements in the process, method, article or device comprising said element.

[0094] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them; it is easy for those skilled in the art to understand that the above description is only a preferred embodiment of the present invention and is not used to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
