[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely to represent selected embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0029] This embodiment connects to the bottom of the billet-taking cart via a guide wheel mechanism. The two guide wheels slide along the bottom rail of the billet-taking cart. Because the guide wheel openings face downwards, mud, water, and other substances from above can be prevented from entering the bearings, greatly ensuring the bearing's service life and preventing mud from clogging the rails and causing corrosion, thus affecting usability. The specific implementation method is as follows:

[0030] like Figures 1 to 5 As shown, a telescopic billet-retrieving guide wheel mechanism includes a mounting plate 1, guide wheels 2, and short shafts 3. The mounting plate 1 is connected to the billet-retrieving equipment. Two short shafts 3 are symmetrically mounted on the mounting plate 1, and two guide wheels 2 are rotatably connected to the two short shafts 3. A channel is formed between the two guide wheels 2, connecting to the bottom slide rail of the billet-retrieving cart. The bottom of the guide wheel 2 has a lower groove for connecting the short shaft 3, and a bearing 4 is installed in the lower groove. The short shaft 3 is inserted through the inner side of the bearing 4. The guide wheel mechanism is connected to the bottom of the billet-retrieving cart, and the two guide wheels 2 are slidably connected to the bottom track of the billet-retrieving cart. Since the opening of the guide wheel 2 faces downward, it can avoid mud, water, and other substances from entering the bearing, greatly ensuring the service life of the bearing 4 and preventing mud from clogging the track and causing the slide rail to rust, thus affecting its use. This significantly reduces the failure rate of the billet-retrieving cart.

[0031] Guide roller 2 is made of ordinary carbon steel. It prevents wear on the bottom slide rail of the billet-taking car and protects the slide rail.

[0032] The upper edge of guide wheel 2 is provided with a wedge-shaped structure that matches the bottom slide rail of the billet-taking cart. The lower edge of guide wheel 2 has a larger diameter than the upper edge. The upper edge of guide wheel 2 is blunted to achieve a perfect fit between guide wheel 2 and slide rail when clamped, ensuring no shaking when the billet-taking cart extends or retracts. When guide wheel 2 is worn, the wedge-shaped structure helps to restore the original fit by tightening the top bolt 6. The lower edge of guide wheel 2 has a slightly larger diameter than the upper edge to provide a safety feature to prevent the billet-taking cart from falling off.

[0033] An elastic retaining ring 8 is provided between the bottom of the bearing 4 and the lower groove of the guide wheel 2, and the upper surface of the elastic retaining ring 8 is in close contact with the bottom of the bearing 4. The bearing 4 is locked in the lower groove by the elastic retaining ring 8.

[0034] A round nut 9 is fitted onto the outer surface of the short shaft 3 between the top of the bearing 4 and the lower groove. A retaining washer 10 is provided between the round nut 9 and the bearing 4. By locking the short shaft 3 with the round nut 9 and the retaining washer 10, the bearing 4 can be prevented from separating from the short shaft 3, and a certain locking strength can be provided.

[0035] A locking nut 5 is threaded onto the bottom of the short shaft 3. A through hole is formed on the bottom surface of the short shaft 3, and an anti-loosening cotter pin 7 is installed inside the through hole. The locking nut 5 locks the rotating shaft of the guide wheel 2 for fixation, facilitating the rotation connection of the guide wheel 2. When it is necessary to replace the internal components of the mechanism, the short shaft can be released by loosening the tightening bolt 6, thereby facilitating quick disassembly and replacement of the mechanism. The anti-loosening cotter pin 7 further prevents the locking nut 5 from loosening.

[0036] Two clamping sleeves 11 are symmetrically installed on the bottom of the mounting plate 1, and two clamping bolts 6 are threaded into each clamping sleeve 11. The clamping bolts 6 can move along the threads of the clamping sleeve 11 and abut against the locking nut 5.

[0037] The surface of the mounting plate 1 has several fixing holes, and the interior of the mounting plate 1 is provided with a pressure-bearing reinforcing plate 12. The fixing holes on the mounting plate 1 facilitate the installation and fixing of the mounting plate 1 and the guide wheel mechanism on the base of the billet taking equipment. The pressure-bearing reinforcing plate 12 inside the mounting plate 1 can improve the strength of the mounting plate 1 and enhance its pressure-bearing and compressive resistance.

[0038] Multiple sets of guide wheel mechanisms can be installed on the base of the billet taking equipment. Each set of guide wheel mechanisms includes two sets of symmetrical guide wheels 2 and their matching bearings 4 and other accessories. The two guide wheels 2 together clamp the bottom slide rail of the billet taking carriage to ensure a stable connection.

[0039] Both the outer surfaces of the mounting plate 1 and the guide wheel 2 are coated with anti-corrosion paint. This prevents corrosion and rust from affecting the use of the guide wheel mechanism. The short shaft 3 is equipped with a long boss, which is embedded in the long hole of the mounting plate 1. This boss serves to fix the short shaft 3 and allow it to slide in the groove. The bottom of the short shaft 3 is milled flat during machining to facilitate wrench clamping during installation.

[0040] Working principle: The guide wheel mechanism is connected to the bottom of the billet taking car. Two guide wheels slide along the bottom rail of the billet taking car. Since the opening of the guide wheel faces downward, it can prevent mud, water and other substances from entering the bearing, greatly ensuring the service life of the bearing and avoiding the phenomenon of mud clogging the rail and causing the slide rail to rust and affect the use. The guide wheel shaft is fixed by locking the locking nut, which facilitates the rotation connection of the guide wheel. When it is necessary to replace the internal components of the mechanism, the short shaft can be released by loosening the tightening bolt, which facilitates quick disassembly and replacement of the mechanism. The fixing holes set on the mounting plate can facilitate the installation and fixing of the mounting plate and the guide wheel mechanism on the billet taking equipment base. The pressure-bearing reinforcing plate set inside the mounting plate can improve the strength of the mounting plate and enhance its pressure resistance.

[0041] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
