Description

Technical Field

[0001] This utility model relates to the field of steel metallurgical equipment technology, specifically to an emergency support device for a moving gear spindle. Background Technology

[0002] In the bar production line of a modern steel rolling mill, the cooling bed system uses the precise lifting and reciprocating motion of a moving rack to achieve the orderly placement and smooth advancement of the reinforcing bars within the slots of the fixed-length rack, thereby completing the cooling process. The precise movement of the moving rack relies on the rotation control of a long spindle driven by a motor and its eccentric wheel. The long spindle is composed of multiple short spindles connected by couplings, and each short spindle is supported by two bearing seats. This structural design not only ensures efficient power transmission but also facilitates the installation and maintenance of the equipment.

[0003] However, the operating environment of the cooling bed spindle bearing housing is extremely harsh, filled with iron oxide scale, and it works under high temperature baking for a long time, which leads to frequent damage to the bearing housing. After the bearing housing is damaged, the moving gear spindle will lose the necessary support, which will cause jamming during the movement of the moving gear, making it impossible to smoothly push the steel bars, ultimately causing the production line to stop and facing a serious risk of downtime. In addition, due to the narrow space of the cooling bed interlayer, the harsh high temperature environment, and the inconvenience of crane operation, the process of replacing the bearing housing usually takes more than five hours, which seriously affects production efficiency and economic benefits. Utility Model Content

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Example 1: Please refer to Figure 1This utility model provides an embodiment of an emergency support device for a moving gear spindle, which is installed at the bottom end of the spindle. It includes a support frame 1, an adjusting base plate 2, a set screw 3, and a support seat 5. The support frames 1 are symmetrically and vertically installed on the left and right sides of the spindle. The support frames 1 on the left and right sides are connected by reinforcing ribs at the bottom of the support frames 1. The support frames 1 are the main structure supporting the entire device. Their vertical installation on the left and right sides of the spindle ensures the stability of the device. The reinforcing ribs at the bottom of the support frames 1 increase the overall structural strength. The symmetrical and vertical structural arrangement improves stability and avoids offset or uneven stress. The corresponding end faces of the left and right support frames 1 are symmetrically provided with sliding grooves, which are located at the corresponding ends of the support frames 1. The front and rear ends of the slide are located at the bottom end of the slide, which is located in the middle of the support frame 1. A support seat 5 is provided in the slide, which is slidably fitted to the support frame 1. An adjusting base plate 2 is provided on the bottom end of the slide. The adjusting base plate 2 is L-shaped and is used to accommodate the set screw 3, so that the set screw 3 supports the support seat 5 and provides a height adjustment function. Its vertical end is connected to the support frame 1, and its horizontal end is located between the end faces of the left and right support frames 1. Through the through hole and nut 4 of the horizontal end, the height of the support seat 5 can be adjusted by rotating the set screw 3 to adapt to the main shaft support of different heights. Its vertical end is connected to the support frame 1, and its horizontal end is located between the corresponding end faces of the left and right support frames 1. A through hole is provided in the middle of the horizontal end. A nut 4 is connected to the through hole, and a set screw 3 is installed inside the nut 4. The set screw 3 works in conjunction with the nut 4, with the external thread of the set screw 3 engaging with the internal thread of the nut 4. The top of the set screw 3 contacts the bottom of the support seat 5. By adjusting the position of the set screw 3, the height of the support seat 5 can be precisely controlled, allowing for adjustments to different spindle heights. This ensures that the outer circumference of the support wheel 8 abuts against the outer circumference of the spindle, providing support for the spindle and ensuring accurate support even in case of failure. The set screw 3 passes through the nut 4 and the through hole, with its top abutting against the bottom of the support seat 5. The support seat 5 is a U-shaped hollow shell with its opening facing upwards, used to support the spindle. The central axis of the U-shaped groove is coaxial with the central axis of the spindle, ensuring that the support seat 5 is precisely aligned with the spindle. This allows the support wheel 8 to support the main shaft, ensuring stable movement. The support base 5 is a U-shaped hollow shell with an upward opening, and the central axis of the U-shaped groove of the support base 5 is coaxial with the central axis of the main shaft. Support wheels 8 are connected to the vertical ends on the left and right sides of the U-shaped end of the support base 5, respectively. The support wheels 8 are mounted on the support base 5 by pins 9. The pins 9 are used to connect the support wheels 8 to the support base 5, and by passing through the front and rear sides of the support base 5, they ensure the secure installation of the support wheels 8, ensuring that the support wheels 8 do not loosen or shift during operation. The front and rear ends of the pins 9 respectively penetrate the support base 5, and the contact ends of the pins 9 and the support base 5 are respectively connected to bearing seats. The bearing seats are used to support and position the pins 9, and at the same time reduce friction when the pins 9 rotate.

[0019] The support wheel 8 is connected to the support seat 5 via the pin 9. The outer circumference of the support wheel 8 contacts the outer circumference of the main shaft, which helps to support the main shaft and reduce friction, ensuring that the main shaft runs smoothly. The support wheel 8 effectively reduces the friction between the main shaft and the support seat 5, extends the service life of the system, and provides smooth operation. The outer circumference of the support wheel 8 abuts against the outer circumference of the main shaft.

[0020] At the front and rear ends of the support base 5, corresponding to the positions of the pin 9, there are baffles 6 connected by clamping screws 7. The clamping screws 7 and baffles 6 work together to fix the position of the pin 9, preventing the pin 9 from shifting or loosening during use. This ensures the stability of the pin 9 and avoids structural loosening caused by vibration, which could cause the pin 9 to shift and fall off, thus failing to support the spindle.

[0021] When the moving gear spindle of the cooling bed system malfunctions, the set screw 3 is rotated, and the external thread of the set screw 3 engages with the internal thread of the nut 4, causing the set screw 3 to rise. The position of the support seat 5 is adjusted according to the height of the spindle, thereby ensuring that the support wheel 8 on the support seat 5 contacts the spindle and provides necessary support, helping to reduce friction and stabilize the spindle movement.

[0022] Example 2: Please refer to Figure 1 Based on Example 1, it also has the following structure:

[0023] The support base 5 has vertically downward extensions on both the left and right sides of its bottom end. These extensions provide installation space for the clamping bolts 10, ensuring they are securely fixed to the support base 5. They also cooperate with the positioning holes. The through-hole design of the extensions allows for quick and tight tightening operations using the clamping bolts 10 during assembly. After height adjustment, the clamping bolts 10 are inserted through the extensions and into the positioning holes, then tightened by the clamping nuts 11. This further restricts the height of the support base 5, ensuring it does not shift during device operation. The extensions have through-holes into which the clamping bolts 10 are installed.

[0024] Several positioning holes are evenly provided between the sliding grooves on the front and rear sides of the support frame 1. The positioning holes are used in conjunction with the clamping bolts 10. The clamping bolts 10 pass through the extension part, and the top end abuts against the inner wall of the positioning hole. They are then tightened by screwing on the clamping nuts 11. When the clamping bolts 10 are connected to the positioning holes of the support frame 1 through the extension part, the clamping nuts 11 are screwed on the bolts. The clamping bolts 10 tighten the connection between the extension part and the support frame 1, ensuring that the connection position is firm and does not loosen. Due to the precise fit between the bolts and the positioning holes, plus the reinforcement of the clamping nuts 11, the firmness of the connection is effectively guaranteed, so that it can cooperate with the set screws 3 to support the support seat 5, ensuring stable support when in contact with the main shaft.

It will be apparent to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this utility model is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this utility model. No reference numerals in the claims should be construed as limiting the scope of the claims.
