Description

Technical Field

[0001] The invention relates to the technical field of coke oven production technology, in particular to a coke oven column pressurizing device. Background Art

[0002] Coke ovens are used to make coal to produce coke. The kiln that uses coal to make coke is the main thermal equipment for coking. The iron parts on the coke oven are responsible for the safety and stability of the coke oven. The iron parts include longitudinal braces, transverse braces, springs, furnace columns, protective plates and furnace door frames. During the production process of the coke oven, it is necessary to adjust the elastic force of the springs in time to adjust the force on the furnace columns to ensure the structural stability of the coke oven body. In the existing coke oven construction, it is usually necessary to manually tighten the nuts to adjust the elastic force of the springs. When the spring is pressed to lock the brace, the spring force will become larger and larger as the brace is tightened step by step, and the tightening work will become more and more difficult, especially when the spring needs to meet the design requirements of large tonnage load. The traditional manual tightening of the nuts requires the cooperation of multiple people, and the operation is laborious, cumbersome and time-consuming, with great safety hazards. It also brings inevitable errors. The tightness of each spring on the same furnace column is inconsistent and cannot meet the construction requirements. Summary of the invention

[0003] The technical problem to be solved by the present invention is the low efficiency of adjusting the spring force by tightening the nut manually and the inconsistent elasticity adjustment.

[0004] In order to solve the above problem, the present invention provides a voltage regulating device capable of improving voltage regulating efficiency, and its specific solution is: A coke oven column pressurizing device is applied to the I-beam of the column, comprising a fastening component fixed on the I-beam of the column and a pressure regulating component for adjusting the fastening component, the fastening component comprising two transverse braces fixedly inserted at the left and right ends of the I-beam of the column, the rear ends of the two transverse braces are sleeved with a fastening plate, each transverse brace between the fastening plate and the column is sleeved with a double-layer spring structure, each transverse brace on the rear side of the fastening plate is threadedly connected with a first nut; the pressure regulating component comprises a fixed bottom plate and clamping plates elastically connected to both sides of the fixed bottom plate, the front ends of the clamping plates on both sides are used to clamp on the flange of the I-beam of the column, a jacking device is arranged on the fixed bottom plate, and the front end of the jacking device is used to abut the fastening plate.

[0005] Compared with the prior art, the present invention using the above technical solution has the following beneficial effects: The present invention is provided with a fastening component and a pressure-adjusting component. The fastening component is fixed on the I-beam of the furnace column. The spring of the fastening component is fastened by a first nut, and the spring is used to increase the pressure of the I-beam of the furnace column. A jacking device is arranged on the fixed bottom plate of the pressure-adjusting component, and the I-beam of the furnace column is clamped by clamping plates on both sides, so that the fixed bottom plate is fixed to the front end of the fastening plate, so that the jacking device drives the fastening plate close to the furnace column, thereby increasing the compression of the spring, and then increasing the pressure of the I-beam of the furnace column, so as to ensure the stability of the coke oven body structure; the stability of the spring deformation is increased by the double-layer spring structure.

[0006] Preferably, a further technical solution of the present invention is: A first pad is sleeved on the transverse brace between the front end of the double-layer spring structure and the furnace column I-beam, the front end of the double-layer spring structure is fixed to the first pad, and the rear end of the double-layer spring structure is fixed to the fastening plate. The first pad increases the deformation pressure area of ​​the furnace column I-beam under the double-layer spring structure, and at the same time, makes the fastening plate structure more stable.

[0007] The double-layer spring structure is composed of an inner ring spring and an outer ring spring. The inner ring spring and the outer ring spring have opposite rotation directions, the outer diameter of the inner ring spring is smaller than the inner diameter of the outer ring spring, and the wire diameter of the inner ring spring is smaller than the wire diameter of the outer ring spring. Through the two springs of different sizes, the outer ring spring with a larger diameter and wire diameter is used as the main source of elastic pressure for the furnace column I-beam, and the inner ring spring mainly plays an auxiliary role.

[0008] A telescopic guide rod is connected between the first pad and the fastening plate, and the telescopic direction of the telescopic guide rod is the same as the elastic deformation direction of the double-layer spring. The telescopic guide rod increases the movement limit of the fastening plate when it moves on the transverse brace, thereby increasing the stability of the fastening plate moving based on the transverse brace.

[0009] The elastic connector is composed of two tension springs. The upper and lower ends of the fixed bottom plate are respectively provided with full-length spring holes. The two tension springs are respectively inserted into the two spring holes. The two ends of the tension springs are respectively vertically fixed to the rear ends of the clamping plates on both sides. Through the above structure, when in use, the distance between the clamping plates on both sides can be expanded by pulling the clamping plates on both sides. When the clamping plates are loosened, the clamping plates can be automatically clamped on the I-beam of the furnace column, thereby fixing the position of the jacking equipment.

[0010] The front ends of the clamping plates on both sides are fixed with clamping edges protruding toward the middle, and the inner ends of the two clamping edges are provided with horizontal slots. When the clamping plates on both sides are clamped on the I-beam of the furnace column, the two clamping edges abut against the flange of the I-beam of the furnace column, and the transverse brace is inserted in the adjacent horizontal slots; the two clamping edges abut against the flange of the I-beam of the furnace column on the upper and lower sides of the transverse brace through the horizontal slots, so that the two clamping edges can be clamped toward the middle of the flange, and at the same time, the clamping plates on both sides can be prevented from moving up and down on the furnace column.

[0011] The two ends of the fixed bottom plate are respectively fixed with guide bars, and the rear ends of the clamping plates on both sides are provided with guide holes matched with the guide bars, and the clamping plates on both sides are slidably arranged on the guide bars through the guide holes. The horizontal movement direction of the clamping plates on both sides is limited by the guide bars.

[0012] A second pad is sleeved on the transverse brace protruding from the front side of the I-beam of the furnace column, and a second nut is threadedly connected on the transverse brace on the front side of the second pad. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0014] The present invention will be further described below in conjunction with embodiments, the purpose of which is only to provide a better understanding of the content of the present invention. Therefore, the examples given do not limit the protection scope of the present invention.

[0015] See attached Figure 1-4The embodiment of the present invention discloses a coke oven column pressurizing device, comprising a fastening component fixed on an I-beam 1 of the column and a pressure regulating component for adjusting the fastening component, wherein the fastening component comprises two transverse braces 2 fixedly inserted at the left and right ends of the I-beam 1 of the column, the front ends of the two transverse braces 2 pass through the upper and lower flanges of the I-beam 1 of the column and extend toward the front end of the I-beam 1 of the column, a fastening plate 33 is sleeved on the rear ends of the two transverse braces 2, a double-layer spring structure 32 is sleeved on each transverse brace 2 between the fastening plate 33 and the column, a first nut 35 is threadedly connected to each transverse brace 2 on the rear side of the fastening plate 33, and the first nut 35 is screwed on each transverse brace 2 to tighten the first nut 33. The fastening plate 33 is abutted against the double-layer spring structure 32; the pressure regulating member includes a fixed bottom plate 43 and clamping plates 42 elastically connected to both sides of the fixed bottom plate 43, the front ends of the clamping plates 42 on both sides are used to clamp on the flange of the furnace column I-beam 1, and a jacking device 41 is arranged in the middle of the front end of the fixed bottom plate 43. Through holes 432 are opened in the fixed bottom plates 43 at both ends of the jacking device 41. When in use, the two transverse braces 2 are passed through the through holes 432 on the fixed bottom plate 43, and the front end of the jacking device 41 is used to abut against the fastening plate 33. Preferably, the jacking device 41 can adopt a linear drive such as a jack, an electric push rod or a hydraulic cylinder.

[0016] In this embodiment, a first pad 31 is sleeved on the transverse brace 2 between the front end of the double-layer spring structure 32 and the furnace column I-beam 1, the front end of the double-layer spring structure 32 is fixed to the first pad 31, and the rear end of the double-layer spring structure 32 is fixed to the fastening plate 33. The first pad 31 increases the area of ​​the furnace column I-beam 1 subjected to the deformation pressure of the double-layer spring structure 32, and the two ends of the double-layer spring structure 32 are respectively fixed to the first pad 31 and the fastening plate 33, so that the fastening plate 33 structure is more stable.

[0017] In this embodiment, the double-layer spring structure 32 is composed of an inner coil spring 322 and an outer coil spring 321. The inner coil spring 322 and the outer coil spring 321 have opposite rotation directions, the outer diameter of the inner coil spring 322 is smaller than the inner diameter of the outer coil spring 321, and the wire diameter of the inner coil spring 322 is smaller than the wire diameter of the outer coil spring 321. Through the two springs of different sizes, the double-layer spring structure 32 has stronger elasticity, more superior horizontal support performance, and is not easy to deform obliquely. The outer coil spring 321 with a larger diameter and wire diameter is the main source of elastic pressure for the furnace column, and the inner coil spring 322 mainly plays an auxiliary role.

[0018] In this embodiment, a telescopic guide rod 34 is connected between the first pad 31 and the fastening plate 33. The telescopic direction of the telescopic guide rod 34 is the same as the elastic deformation direction of the double-layer spring. The telescopic guide rod 34 increases the movement limit of the fastening plate 33 when it moves on the transverse brace 2, thereby increasing the stability of the fastening plate 33 moving based on the transverse brace 2.

[0019] In this embodiment, the elastic connector is composed of two tension springs 433. The upper and lower ends of the fixed bottom plate 43 are respectively provided with through-length spring holes. The two tension springs 433 are respectively inserted into the two spring holes. The two ends of the two tension springs 433 are respectively vertically fixed to the rear ends of the clamping plates 42 on both sides. With the above structure, when in use, the clamping plates 42 on both sides are pulled to stretch the tension springs 433, so that the distance between the clamping plates 42 on both sides can be expanded. The clamping plates 42 on both sides can be automatically clamped on the furnace column by loosening the clamping plates 42 on both sides, thereby fixing the position of the jacking device 41.

[0020] In this embodiment, the front ends of the clamping plates 42 on both sides are fixed with clamping edges 44 protruding toward the middle position, and the clamping edges 44 and the clamping plates 42 are an integrally formed L-shaped structure. Horizontal slots 441 are provided at the middle horizontal positions of the inner ends of the clamping edges 44 on both sides, and the transverse brace 2 is inserted in the adjacent horizontal slots 441. When the clamping plates 42 on both sides are clamped on the furnace column I-beam 1, by setting the horizontal slots 441, the inner ends of the clamping edges 44 can pass through the transverse brace 2 as close to the web of the furnace column I-beam 1 as possible, so that the rear walls of the two clamping edges 44 abut against the flanges of the furnace column I-beam 1 on the upper and lower sides of the transverse brace 2, and then the front ends of the two clamping plates 42 can abut against the two ends of the rear end flange of the furnace column I-beam 1; at the same time, when the pressure regulating component moves downward under the influence of its own weight, the horizontal slots 441 can prevent the pressure regulating component from moving up and down on the furnace column, thereby increasing the stability of the pressure regulation.

[0021] In this embodiment, guide bars 431 are fixed to both ends of the fixed bottom plate 43, and the length direction of the guide bars 431 at both ends is consistent with the length direction of the fixed bottom plate 43. The rear ends of the clamping plates 42 on both sides are provided with guide holes that match the guide bars 431, and the clamping plates 42 on both sides are slidably arranged on the guide bars 431 through the guide holes. When the clamping plates 42 on both sides are bent outward, the moving direction of the clamping plates 42 on both sides is limited by the guide bars 431, so that the clamping plates 42 can only move horizontally perpendicular to the fixed bottom plate 43, thereby facilitating the stretching of the spring. After the clamping plates 42 on both sides are released, the spring automatically rebounds, driving the rear ends of the clamping plates 42 on both sides to approach the fixed bottom plate 43.

[0022] In this embodiment, a second pad 36 is sleeved on the two transverse braces 2 protruding from the front side of the furnace column I-beam 1, and a second nut 37 is threadedly connected to the transverse brace 2 on the front side of the second pad 36, and the front end of the transverse brace 2 is fastened to the front side of the furnace column I-beam 1 through the second nut 37.

[0023] When the device of the present invention is used for pressurizing, the two side clamps 42 of the pressure regulating member are opened and moved forward so that the two transverse braces 2 pass through the through holes 432 on the fixed bottom plate 43 until the front end of the clamps 42 can be clamped on the flange of the furnace column I-beam 1, and the two side clamps 42 are loosened. Driven by the tension spring 433, the two side clamps 42 move toward the middle, and the front end of the clamps 42 is clamped on the flange of the furnace column I-beam 1. At this time, the jacking device 41 on the fixed bottom plate 43 is located at the rear end of the fastening plate 33. The jacking device 41 is turned on to drive the fastening plate 33 to move forward. At this time, the double-layer spring structure 32 is gradually compressed, so that the pressure at the position of the furnace column I-beam 1 corresponding to the double-layer spring structure 32 increases; after the pressurization is completed, the first nut 35 is tightened to fix the The compression amount of the double-layer spring structure 32 is fixed, and then the clamping plate 42 is pried open to remove the pressure-adjusting component. The present invention is provided with a fastening component and a pressure-adjusting component. The fastening component is fixed on the furnace column I-beam 1. The spring of the fastening component is fastened by a first nut 35, and the spring is used to increase the pressure of the furnace column I-beam 1. A jacking device 41 is arranged on the fixed bottom plate 43 of the pressure-adjusting component, and the furnace column I-beam 1 is clamped by the clamping plates 42 on both sides, so that the fixed bottom plate 43 is fixed to the front end of the fastening plate 33, so that the jacking device 41 drives the fastening plate 33 close to the furnace column, thereby increasing the compression amount of the spring, and then increasing the pressure of the furnace column I-beam 1 to ensure the stability of the coke oven body structure. The double-layer spring structure 32 is used to increase the stability of the spring deformation.
