Description

Technical Field

[0001] This utility model relates to the technical field of I-beam repair equipment, specifically an I-beam shaping machine. Background Technology

[0002] I-beams are a common material in mining production. In mines, I-beams bend and deform due to long-term exposure to huge loads, geological pressure, or accidental impacts. The bent and deformed I-beams cannot be reused, resulting in scrap and material waste. Existing forming machines use a frame to place the I-beams into the frame for forming. However, during the forming process, because the size of the I-beams is smaller than the size of the frame, the I-beams wobble and shift during the forming process. Utility Model Content

[0003] The purpose of this utility model is to provide an I-beam forming machine to solve the problem that existing forming machines use a frame to place the I-beam into the frame for forming. However, during the forming process, the I-beam is smaller than the frame, which causes it to sway and deviate during the forming process.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an I-beam forming machine, comprising an operating table, a jack, and auxiliary devices. Vertical support columns are connected to the four corners of the bottom of the operating table, and these support columns are inserted into pre-drilled mounting holes in the ground. A jack is installed on one side of the top of the operating table, and a detachable top plate is connected to the top of the jack's piston rod. Auxiliary devices are symmetrically arranged on both the front and rear sides of the other end of the operating table. The auxiliary device includes a mounting platform, a threaded rod, and an auxiliary pressure plate. The mounting platform is L-shaped, with its vertical end fixedly connected to the operating table. A baffle is connected between the corresponding end faces of the vertical end, and the baffle abuts against the I-beam. A threaded hole is opened on the horizontal end of the mounting platform, and a threaded rod is installed in the threaded hole. An adjusting handwheel is connected to the top end of the threaded rod, and an auxiliary pressure plate is connected to the bottom end. An I-beam is placed between the auxiliary pressure plate and the operating table, and the upper and lower ends of the I-beam abut against the auxiliary pressure plate and the operating table, respectively.

[0005] Preferably, the contact end between the threaded rod and the auxiliary pressure plate is connected to a bearing seat.

[0006] Preferably, the top of the operating platform is connected to a limiting platform, which abuts against the cylinder of the jack.

[0007] Preferably, it also includes a retaining ring connected to the outer circumference of the jack, and the retaining ring is connected to the operating table by bolts.

[0008] Preferably, the height of the baffle is flush with the height of the vertical end of the mounting platform.

[0009] Compared with the prior art, the beneficial effects of this utility model are: By setting up an installation platform on the operating table, the threaded rod on the installation platform rotates, pressing down the auxiliary pressure plate to abut against the I-beam, thus cooperating with the operating table to firmly clamp the I-beam and reduce shaking and displacement during shaping.

[0016] 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.

[0017] Example 1: Please refer to Figure 1-2 This utility model provides an embodiment of an I-beam forming machine, comprising an operating platform 1, a base platform and a working surface for the entire device. Support columns 2 support jacks 3, auxiliary devices, and the I-beam to be processed. The I-beam is placed directly on the operating platform 1, providing a flat and stable support surface. The operating platform 1 has four vertically erected support columns 2 connected to its bottom corners. The support columns 2 are inserted into pre-drilled mounting holes in the ground, firmly fixing the operating platform 1 to the ground and ensuring that the entire device will not shift when a jacking force is applied, thus guaranteeing operational safety and accuracy. A jack 3 is installed on one side of the top of the operating platform 1, providing the main jacking force. Its piston rod extends out and passes through a top plate 6. The jack 3 is used to press down on the web of the I-beam or the part that needs to be corrected, causing it to deform or shift, thereby achieving shaping and reuse. The jack 3 used in this application is a conventional commercially available jack 3, and its operation is prior art, which will not be elaborated upon here. A detachable top plate 6 is connected to the top of the piston rod of the jack 3, serving as the direct force application point on the I-beam to be corrected. This increases the contact area, prevents the piston rod tip from pressing into the I-beam and causing localized damage, protects the surface of the I-beam, and adapts to different contact surface requirements. The detachable design allows for easy replacement of top plates 6 of different shapes or sizes to accommodate different specifications of I-beams or different force application needs. Auxiliary devices are symmetrically arranged on both the front and rear sides of the other end of the operating platform 1. The auxiliary device includes a mounting platform 7, a threaded rod 8, and an auxiliary pressure plate 9. The mounting platform 7 is L-shaped, with its vertical end fixedly connected to the operating platform 1. The base of the auxiliary device is also L-shaped, with its vertical end fixed to the side of the operating platform 1, providing height support. It is suitable for different I-beam shaping specifications, allowing the auxiliary pressure plate 9 to be positioned at a suitable height above the working surface of the operating platform 1, forming sufficient space for I-beam placement. A baffle 10 is connected between the corresponding end faces of the vertical ends, abutting against the I-beam. It is connected between the vertical ends of the two mounting platforms 7, directly abutting against the shaped end face of the I-beam, ensuring that the adjusted I-beam remains horizontal. A threaded hole is provided on the horizontal end of the mounting platform 7, and a threaded rod 8 is provided in the threaded hole. An adjusting handwheel is connected to the top of the threaded rod 8. By rotating the adjusting handwheel, the threaded rod 8 is driven to move up and down in the threaded hole at the horizontal end of the mounting platform 7, thereby driving the auxiliary pressure plate 9 to rise and fall, so that the auxiliary pressure plate 9 presses the I-beam to accommodate I-beams of different heights and specifications. The bottom end is connected to the auxiliary pressure plate 9, which directly presses the upper part of the I-beam and clamps the I-beam together with the operating table 1. The auxiliary pressure plate 9 and the operating table 1 form a space for placing the I-beam, and together with the operating table 1, they clamp the end of the I-beam. The upper and lower ends of the I-beam respectively abut against the auxiliary pressure plate 9 and the operating table 1.

[0018] The threaded rod 8 and the auxiliary pressure plate 9 are connected to a bearing seat at their contact ends, so that the auxiliary pressure plate 9 does not rotate when the threaded rod 8 rotates and presses down. During the clamping process, the auxiliary pressure plate 9 will not rub against the surface of the I-beam, ensuring that the pressure plate can flatly clamp the I-beam. The top of the operating platform 1 is connected to a limit platform 4, which abuts against the cylinder of the jack 3. The limit platform 4 and the fixing ring 5 work together to firmly install the jack 3 on the operating platform 1. The platform also includes a fixing ring 5, which is connected to the outer circumference of the jack 3. The fixing ring 5 is connected to the operating platform 1 by bolts, which firmly fixes the cylinder of the jack 3 on the operating platform 1, preventing the jack 3 from shifting or tilting during the application of force, ensuring that the direction of force application of the jack 3 is accurate, and preventing it from moving backward or tilting due to reaction force, thus ensuring power transmission efficiency and operational safety. The bolt connection facilitates installation and disassembly. The height of the baffle 10 is flush with the vertical end of the mounting platform 7, ensuring sufficient contact area with the end face of the I-beam.

[0019] In use, first insert the support column 2 of the operating platform 1 into the pre-drilled hole in the ground. Install the appropriate top plate 6 onto the piston rod of the jack 3 as needed. Place the jack 3 on the operating platform 1, with the cylinder body against the limit plate 4, and secure it firmly to the operating platform 1 using the fixing ring 5 and bolts. Then, place the I-beam under the auxiliary device, rotate the adjusting handwheels on the two auxiliary devices to drive the threaded rod 8 downwards, simultaneously causing the auxiliary pressure plate 9 to press down. The auxiliary pressure plate 9 presses against the upper part of the I-beam, and the lower part... The operating platform 1 firmly clamps the bottom of the I-beam, and the jack 3 is driven to extend its piston rod. The top plate 6 at the top of the piston rod contacts the part of the I-beam that needs to be corrected. After being shaped, the I-beam abuts against the baffle 10, achieving the required pushing displacement or correction effect. At this time, the jack 3 is stopped, and its piston rod is retracted. The top plate 6 is removed from the I-beam. The adjusting handwheel of the auxiliary device is rotated to raise the auxiliary pressure plate 9, releasing the clamp on the end of the I-beam and removing the processed I-beam to prepare for the next work cycle.

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.
