Description

Technical Field

[0001] The utility model relates to the technical field of installation and debugging of annular coolers, in particular to an auxiliary device for installing a supporting roller of annular coolers. Background Art

[0002] The multifunctional blast ring cooler (hereinafter referred to as ring cooler) is one of the most important equipment in the steel production process. Today, as ring coolers are large-scale, they must be assembled and debugged on site. The quality of their on-site installation is directly related to the operating performance and service life of the ring cooler.

[0003] During the operation of the ring cooler, several rotating frame trolleys connected to form a circular motion are used to support the hot ore. The blowers evenly distributed on the periphery of the ring cooler blow out cold air through the lower half of the rotating frame trolley through the hot material layer to exchange heat, and use the exhaust gas to take away the heat to achieve hot ore cooling. Therefore, the stable operation of the rotating frame is very important for the ring cooler.

[0004] The support rollers serve as the basis for supporting the slewing frame trolley to realize circumferential motion. When the slewing frame trolley is running on the support roller track, the centrifugal force will form an axial load on the support rollers. In addition, the support rollers work under comprehensive operating conditions such as dust and alternating temperature changes, resulting in a high failure rate, and their position accuracy and geometric dimensions are prone to deviation. Therefore, the position accuracy of the support rollers is directly related to the stability of the slewing frame trolley during operation, which in turn determines whether the slewing frame trolley can operate safely and smoothly in actual production operations. Therefore, whether the support rollers are installed during the original design or the position of the support rollers is regularly calibrated and measured later, the position accuracy of the support rollers needs to be measured and located.

[0005] like Figure 1As shown, multiple support rollers are respectively installed on the upper plane of the main beam and the middle beam of the frame plane beam around the central measuring platform. There are two support rollers on each single main beam or middle beam, which are symmetrically arranged on both sides of the ring center line of the ring cooler (that is, divided into inner ring support rollers and outer ring support rollers). Several support rollers are combined to form two support rings located on both sides of the ring center line for supporting the rotating body. In the traditional measurement method, a total station electronic distance meter (hereinafter referred to as the total station) set up on the central measuring platform is used to measure and locate the inner ring support roller. However, an inner ring column for installing components such as plane beams and side rollers is provided in the ring cooler, and the inner ring column will block the field of view on part of the inner ring support roller, resulting in some inner ring support rollers being unable to be measured by the total station. At the same time, the inner ring support roller also blocks the outer ring support roller, making it impossible to directly observe and locate the outer ring support roller. The only way is to measure the relative installation distance between the inner ring support roller and the outer ring support roller by pulling a wire or measuring tape, which brings great inconvenience to the installation and measurement of the support rollers and cannot guarantee the measurement accuracy. Therefore, it is urgent to develop a set of installation auxiliary tools suitable for the positioning measurement of the support rollers of the ring cooler. Summary of the invention

[0006] The utility model provides a ring-type cooler support roller installation auxiliary device, which solves the technical problems of inconvenient observation, complicated procedures, low measurement accuracy and the like brought about by traditional measurement methods.

[0012] Furthermore, a level ruler is provided on the top surface of the base, and the horizontal position between the base and the support seat is adjusted by a gasket.

[0032] Reference Figures 2 to 5 As shown, a ring-type cooler support roller installation auxiliary device includes a base 1, a wing plate 2, a mandrel 3, a total station 4 and a laser level.

[0033] The base 1 is used to be placed on the top of the support seat 6 of the inner ring support roller 5, and the top surface of the base 1 is arranged in the horizontal direction; in order to ensure the horizontal position of the top surface of the base 1, a level ruler can be placed on the top surface of the base 1, and the base 1 and the support seat 6 are adjusted by gaskets to make the top surface of the base 1 in a horizontal state.

[0034] The wing plate 2 is horizontally arranged on the top surface of the base 1 and is symmetrically distributed with respect to the vertical bisector of the inner ring support roller 5; the back side surface of the wing plate 2 abuts against the front side wall surface of the inner ring support roller 5; specifically, a central vertical scale line 11 is provided on the front side end surface of the base 1, a laser level is arranged on the axis from the central hole of the inner ring support roller 5 to the center of the ring cooler, and a vertical laser line is projected along the central hole of the inner ring support roller 5 to form the intersection line of the vertical bisector of the inner ring support roller 5 on the roller body, the central vertical scale line of the base 1 coincides with the vertical laser line, and the reference position calibration of the base 1 is completed. In order to facilitate the installation of the wing plate 2, the wing plate 2 can be fixedly welded to the top end surface of the base 1, and the wing plate 2 is set as a rectangular parallelepiped as a whole. A vertical scale line 21 is respectively provided on the front side surfaces at both ends of the wing plate 2, and the two vertical scale lines 21 are symmetrically distributed with respect to the central vertical scale line of the base. In this state, the base 1 and the wing plate 2 form the measurement reference of the inner ring support roller 5.

[0035] The total station 4 is set at the center of the ring cooler. The total station 4 is used to cooperate with the wing plate 2 to detect and calibrate the installation position of the inner ring support roller 5. The total station 4 is used to measure the actual value of the distance K between the center of the ring cooler and the two vertical scale lines 21 of the wing plate 2, and the left K and the right K are obtained. The axial installation position of the inner ring support roller 5 is adjusted and calibrated according to the deviation between the left K and the right K; the lateral distance between the vertical scale lines 21 on the left and right sides of the wing plate 2 is w, and the distance from one vertical scale line 21 to the perpendicular bisector of the inner ring support roller 5 is w / 2. The thickness of the wing plate 2 is d. According to the geometric relationship of the triangle, the actual distance K1 between the front wall of the inner ring support roller 5 and the center point of the ring cooler is calculated, that is,

[0036] Then, the vertical offset e from the center of the ring cooler to the central axis of the inner ring support roller 5 is calculated based on the difference between the sum of K1 and d and the design dimension value R1, that is, e=R1-K1-d. The radial installation position of the inner ring support roller 5 is adjusted and calibrated so that the vertical offset e is approximately 0. When adjusting the vertical offset e, make sure that the deviation of the left K and the right K is within the acceptable range. The position of the inner ring support 5 can be fixed until the vertical offset e and the deviations of the left K and the right K meet the requirements.

[0037] After the positioning and installation of the inner ring support roller 5 is completed, the positioning and installation of the outer ring support roller 7 is completed by the mandrel 3. The two end faces of the mandrel 3 are respectively attached to the rear wall surface of the inner ring support roller 5 and the front wall surface of the outer ring support roller 7, and the mandrel 3 and the axis of the inner ring support roller 5 and the outer ring support roller 7 are at the same horizontal height. Specifically, the number of the mandrels 3 is set to two, and both ends of the mandrel 3 are provided with right-angle notches 31, and the right-angle notches 31 are formed with transverse surfaces and longitudinal surfaces. When making the right-angle notches 31 of the mandrel, they can be directly cut and processed on the mandrel; two wedge blocks 32 can also be set, and a bayonet is set at both ends of the mandrel 3, each wedge block 32 is embedded in the corresponding bayonet and welded and fixed, and the right-angle notch 31 is set on the wedge block 32; it should be noted that the two transverse surfaces on each mandrel 3 must be parallel to each other, and the two longitudinal surfaces on each mandrel 3 must be located in the same plane. The transverse surfaces at both ends of each of the mandrels 3 are respectively fitted with the side wall surface of a corresponding support roller, and the longitudinal surfaces at both ends of each of the mandrels 3 are respectively fitted with the rim of a corresponding support roller. The mandrels 3 have right-angle notches at both ends to ensure that they can stably fit the rim of the support roller and ensure that two mandrels 3 of the same length are parallel to the axis of the support roller, thereby ensuring the relative installation position size between the outer ring support roller 7 and the inner ring support roller 5; when the mandrels 3 are installed according to the technical requirements, the installation position state of the outer ring support roller 7 can be truly reflected. The gap n between the transverse surface of the right-angle notch 31 and the side wall surface of the corresponding roller body and the gap m between the longitudinal surface of the right-angle notch 31 and the rim of the corresponding roller body are measured by a feeler gauge. The offset of the outer ring support roller 7 in the axial position and radial position can be obtained through the gaps between the mandrel 3 and each fitting surface of the corresponding roller body, and then the installation position of the outer ring support roller 7 is adjusted until the gaps n and m meet the installation position size requirements.

[0038] The utility model designs a symmetrical wing plate 2 structure, which solves the technical problems of inconvenient observation, complicated procedures, low measurement accuracy and the like caused by the sight obstruction of the inner ring column in the traditional installation scheme. The total station installed in the center of the ring cooler can avoid the sight obstruction of the inner ring column and directly observe the vertical scale line of the wing plate 3, which can make the indirect observation of multiple measurement reference conversions become direct visual observation, and make some undetectable items measurable. The ring can be directly measured from the center of the ring cooler to measure one circle, measure all the inner ring support rollers at one time, and accurately adjust the outer ring support roller 7 according to the inner ring support roller 5. The detection is intuitive and convenient, the detection efficiency is greatly improved, and higher reliability and accuracy can be guaranteed.

[0039] When the installation positions of the inner ring support roller 5 and the outer ring support roller 7 are determined, the installation reference point R0 of the revolving frame trolley can be obtained. In order to facilitate the acquisition of the installation reference point of the revolving frame trolley, a symmetrical horizontal scale line 33 is provided at the center of the top surface of the push rod 3, and the push rod 3 is symmetrically distributed with the symmetrical horizontal scale line 33. The laser level is placed on the plane beam between the inner ring support roller 5 and the outer ring support roller 7, so that the longitudinal horizontal laser line projected by the laser level is aligned with the central axis of the inner ring support roller 5 and the central axis of the outer ring support roller 7 at the same time, and the transverse horizontal laser line projected by the laser level is aligned with the symmetrical horizontal scale lines 33 of the two push rods 3 at the same time, and finally the longitudinal horizontal laser line projected by the laser level and the transverse horizontal laser line form a cross line, and the intersection of the cross lines is the center reference point R0 for installing the revolving frame trolley.

[0040] The above embodiments are only used to illustrate the technical solution of the utility model but not to limit it.
