Description

Technical Field

[0001] The invention relates to the technical field of bearing seat installation, and in particular to a bearing seat installation device. Background Art

[0002] In the dry dust removal area of ​​the blast furnace, the head wheel of the scraper has been in use for a long time, resulting in serious wear of the head wheel of the scraper (the rotating wheel at the higher end of the scraper), and it often needs to be replaced every once in a while. Unlike general bearing seats, the bearing seat used for the head wheel axle of the scraper is an integrated bearing seat. Therefore, when replacing the head wheel of the scraper, the bearing seat needs to be removed together with the head wheel. During the installation process, the online installation method of the bearing seats on both sides is installed by hanging the head wheel with a crane. This online installation method has its insurmountable technical defects, that is, the head wheel is suspended in the air, lacks support and fixing points, which makes the bearing seat extremely difficult to install, and even causes the bearing seat to slip, causing mechanical damage. At the same time, since the mounting surface of the bearing seat is mostly an inclined surface or even a vertical surface, the bearing in the bearing seat deviates during the clamping operation (the distance between the end face of the bearing seat and the end face of the head wheel cannot meet the requirements), and it needs to be adjusted many times. Therefore, the existing replacement method of the bearing seat is time-consuming and labor-intensive, and the operation efficiency is low. Summary of the invention

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0031] Furthermore, in the description of the present invention, unless otherwise specified, “plurality” means two or more.

[0032] Examples, such as Figure 1 As shown, a bearing seat installation device comprises:

[0033] Base 10;

[0034] A first support mechanism 20, the first support mechanism 20 is disposed on the base 10, and the first support mechanism 20 has a placement groove 23 that matches the head wheel shaft 40, so that the first support mechanism 20 supports the head wheel shaft 40;

[0035] The second support mechanism 30, there are two second support mechanisms 30, which are respectively arranged on the left and right sides of the first support mechanism 20 and connected to the base 10. The height of the second support mechanism 30 is adjustable so that the second support mechanism 30 can support the bearing seats 50 installed at both ends of the head wheel shaft 40 and make the head wheel shaft 40 break away from contact with the first support mechanism 20.

[0036] The present application provides horizontal support for the head wheel shaft 40 through the first support mechanism 20, so as to facilitate the sleeve of the bearing seat 50 on the end of the head wheel shaft 40 and prevent the bearing seat 50 from accidentally slipping off, and then supports the bearing seat 50 through the height-adjustable second support mechanism 30, and makes the head wheel shaft 40 disengage from the first support mechanism 20, thereby ensuring that the bearings in the bearing seats 50 at both ends of the head wheel shaft 40 are locked with the head wheel shaft 40 at the same height, and preventing the occurrence of deviation, thereby realizing the offline installation of the head wheel shaft 40 and the bearing seat 50, ensuring the installation accuracy of the bearing seat 50, and then reducing the risk of being hit by objects through the overall lifting method, reducing the labor burden of employees, and improving work efficiency.

[0037] In a specific embodiment, if Figure 1 As shown, the first support mechanism 20 includes a mobile support frame 21 and a fixed support frame 22, and a placement groove 23 is provided on the mobile support frame 21 and the fixed support frame 22; along the length direction of the base 10, the distance between the mobile support frame 21 and the fixed support frame 22 is adjustable. With such an arrangement, the first support mechanism 20 can support both the axle of a single-head wheel and the axle of a double-head wheel, thereby expanding the application range of the device.

[0038] Preferably, a connecting plate 24 is provided at the bottom of the mobile support frame 21, two first connecting holes are provided on the connecting plate 24, and two first slots are provided on the base 10, and the first connecting holes correspond to the first slots one by one and are connected by bolts and nuts. Such a configuration facilitates the mobile support frame 21 to move and fix on the base 10, and realizes the adjustment of the distance between the mobile support frame 21 and the fixed support frame 22.

[0039] More preferably, the placement groove 23 is a U-shaped groove or a V-shaped groove; when the placement groove 23 is a V-shaped groove, the first supporting mechanism 20 can support the head wheel shaft 40 with different radial sizes.

[0040] In a specific embodiment, if Figure 1As shown, the second support mechanism 30 includes an upper support plate 31 and a lower support plate 32 with adjustable spacing, the lower support plate 32 is connected to the base 10, and the upper support plate 31 is used to support the bearing seat 50. In this way, the bearing seats 50 at both ends of the head wheel shaft 40 are locked with the head wheel shaft 40 in the same horizontal plane (that is, at the same height); when the bearing of the bearing seat 50 is tightened with the head wheel shaft 40, under the gravity of the head wheel shaft 40, the bearing seat 50 is pressed against the second support mechanism 30, which can prevent the occurrence of deviation.

[0041] Preferably, a connecting screw 33 is provided between the upper support plate 31 and the lower support plate 32, the top end of the connecting screw 33 is inserted into the guide hole of the upper support plate 31, and the bottom end is inserted into the guide hole of the lower support plate 32; the top and bottom ends of the connecting screw 33 are both threadedly connected with an adjusting nut 34, and the two adjusting nuts 34 are located between the upper support plate 31 and the lower support plate 32, and respectively form a stopper with the upper support plate 31 and the lower support plate 32. In this way, by rotating the adjusting nut 34, the distance between the upper support plate 31 and the lower support plate 32 can be adjusted.

[0042] More preferably, the distance between the two second support mechanisms 30 is adjustable along the length direction of the base 10. This arrangement enables the second support mechanism 30 to install the bearing seats 50 with different installation spacing requirements.

[0043] Preferably, the lower support plate 32 is provided with a second connection hole, and the base 10 is provided with a second slotted hole, and the second connection hole and the second slotted hole correspond to each other and are connected by bolts and nuts. Such a configuration facilitates the movement and fixation of the second support mechanism 30 on the base 10, and realizes the adjustment of the distance between the two second support mechanisms 30.

[0044] In a specific embodiment, if Figure 1 As shown, a lifting lug 13 is provided on the base 10. Such arrangement facilitates the transportation of the device.

[0045] Preferably, the base 10 includes an upper I-beam 11 and a lower I-beam 12, and the two lower I-beams 12 are respectively vertically connected to the two ends of the upper I-beam 11; the first slot and the second slot are arranged on the upper I-beam 11 along the length direction, and the lugs 13 are arranged on the two ends of the lower I-beam 12. Such an arrangement facilitates the arrangement of the first slot, the second slot and the lug 13 on the base 10.

[0046] The use process of the device of the present invention is as follows:

[0047] Before replacing the head wheel, measure the distance between the mounting holes of the two bearing seats 50 at the ends of the head wheel shaft 40 in advance, and fix the two second support mechanisms 30 on the base 10 based on this distance. After completing the replacement of the head wheel, place the head wheel shaft 40 into the placement groove 23 of the first support mechanism 20 (the head wheel is located between the movable support frame 21 and the fixed support frame 22), and then insert the bearing seats 50 into the two ends of the prepared head wheel shaft 40, and then adjust the height and parallelism of the two upper support plates 31 by rotating the adjusting nut 34 on the connecting screw 33 to support the two bearing seats 50 (make sure that the head wheel shaft is out of contact with the first support mechanism 20), and finally level and align the bearing seats 50, tighten the bearings, and make fine adjustments through the tightening sleeve to ensure that the bearing clearance meets the requirements. At the same time, when the second support mechanism 30 supports the bearing seats 50, it is necessary to ensure that the spacing between the bearing seats 50 and the head wheel and the distance between the bearing seats 50 meet the installation requirements.

[0048] There are 21 scrapers in the dry process area of ​​a blast furnace. The replacement cycle of the scraper head wheel is one year, and the replacement cycle of the scraper chain is half a year. When replacing, 5 people are required and it takes 8 hours. After using the above device, the manpower is reduced to three people and the time is reduced to 4 hours. The economic benefits are as follows:

[0049] A. Labor cost for 5 people per day: 5*1*426.65=2133.25 yuan

[0050] B. 0.5-day labor cost for 3 people: 3*0.5*426.65=640 yuan

[0051] B = 1493.25 yuan

[0052] There are 42 scrapers in total in the two blast furnaces. If all of them are replaced in one year, the head wheel needs to be disassembled and installed 126 times, which can save: 1493.25*126=188,100 yuan.

[0053] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principles of the present invention. These improvements and substitutions should also be regarded as the scope of protection of the present invention.
