Description

Technical Field

[0001] This application relates to the field of beam frames for anchoring centers, and in particular to a foldable beam frame structure for anchoring centers. Background Technology

[0002] In underground mines, belt conveyors are a crucial component of the transportation system, used to transport materials such as ore and coal. When belts malfunction due to wear, breakage, or other reasons and need replacement, lifting equipment can quickly lift and remove the old belt while simultaneously transporting the new belt to a suitable location for replacement. This reduces the time and labor costs associated with belt replacement and minimizes the impact on production.

[0003] The lifting device is installed on the beam frame, but the current beam frames are usually fixed with bolts, especially for longer beam frames that require multiple sections to be bolted together. This type of beam frame not only requires a lot of manpower and time to tighten the bolts when connecting and disassembling the sections, but also occupies a lot of space when not in use. Utility Model Content

[0004] To address the problem of consuming significant manpower and time to tighten bolts when connecting and disassembling long beams, resulting in a complex operation process and occupying a large amount of space when idle, this application provides a foldable beam structure for fastening the center.

[0005] The foldable beam frame structure for fastening center provided in this application adopts the following technical solution:

[0006] A foldable beam frame structure for fastening a center includes two support columns, with a crossbeam fixed to one adjacent side of each support column. A left rail is vertically fixed to the crossbeam, and a right rail is provided at one end of the left rail. A cylinder is hinged to the frame, a support frame is fixed to the left rail, a pin is fixed to the support frame, a rotating block rotates on the pin, the rotating block is fixed to the right rail, and a mounting plate is fixed to the right rail. A T-slot is provided on the mounting plate, and a T-block slides on the T-slot. The piston rod of the cylinder is hinged to the T-block.

[0007] By adopting the above technical solution, this foldable beam frame structure can achieve rapid folding and unfolding between the left and right tracks. Specifically, the piston rod of the cylinder, through hinge with the T-block, drives the right track to rotate along the end of the left track, thereby adjusting the position of the right track. This foldable beam frame structure not only avoids the cumbersome operation problems caused by traditional bolt fixing methods, but also significantly improves the flexibility and adaptability of the beam frame. At the same time, the cooperation between the pin and the rotating block ensures the stability of the right track rotation process, further enhancing the reliability of the overall structure. In addition, this structure can effectively reduce the space occupied when not in use, providing greater convenience for practical applications.

[0008] Optionally, there is a gap between the left track and the right track, the left track is arranged in an arc shape on the side closer to the right track, and the right track is arranged in an arc shape on the side closer to the left track.

[0009] By adopting the above technical solution, a gap is set between the left and right tracks, with the left track having an arc-shaped side closer to the right track, and the right track having an arc-shaped side closer to the left track. This ensures smooth rotation of the right track on the left track. This not only improves the folding and unfolding efficiency of the beam frame but also extends the service life of the tracks.

[0010] Optionally, the rotating block is located inside the receiving frame, and the edges of the rotating block are arranged in an arc shape.

[0011] By adopting the above technical solution, the rotating block is located inside the receiving frame, which effectively limits the range of motion of the rotating block. At the same time, setting the edges of the rotating block to be arc-shaped can reduce the frictional resistance of the rotating block during rotation, ensuring the smooth folding and unfolding of the beam frame structure.

[0012] Optionally, the receiving frame is arranged in an arc shape on the side near the right track.

[0013] By adopting the above technical solution, the arc-shaped arrangement of the receiving frame near the right track can reduce the frictional resistance of the right track during rotation, making the rotation of the right track smoother, thereby improving the folding and unfolding efficiency of the beam frame structure.

[0014] Optionally, the cross-sections of both the left and right tracks are arranged in an I-shape.

[0015] By adopting the above technical solution, both the left and right rails have an I-shaped cross-section, which improves the overall strength and stability of the rails while reducing material usage and overall weight. The I-shaped design gives the rails better bending resistance when subjected to external forces, thus ensuring the reliability of the beam structure during use. Furthermore, it facilitates the sliding of the lifting device on the left and right rails.

[0016] Optionally, a pressure body is provided above the receiving frame, and two bolts are threaded onto the pressure body. The pressure body and the receiving frame are fixed by the two bolts.

[0017] By adopting the above technical solution, the pressure body and the receiving frame are fixed together by two bolts, so that the pressure body can be stably installed on the receiving frame, while facilitating disassembly and adjustment.

[0018] In summary, this application includes at least one of the following beneficial technical effects:

[0019] 1. By driving the right track to rotate relative to the left track with a cylinder, the beam frame can be folded, which significantly reduces the space occupied by the beam frame when it is not in use and improves the space utilization rate.

[0020] 2. The arc-shaped fit design between the left and right tracks, combined with the rotating block's rotation connection, makes the folding and unfolding of the beam frame more convenient, significantly reducing the complexity and time cost of manual operation;

[0021] 3. The sliding fit structure of the T-slot and T-block, combined with the piston rod drive of the cylinder, can precisely control the movement trajectory of the right track, ensuring the stability and reliability of the beam frame during folding and unfolding. Attached Figure Description

[0029] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0030] This application discloses a foldable beam frame structure for fastening a center.

[0031] Reference Figure 1 A foldable beam frame structure for fastening the center includes two support columns 1, with a crossbeam 2 fixed between the two support columns 1. The combination of the two support columns 1 and the crossbeam 2 provides a stable foundation support for the entire beam frame.

[0032] Reference Figure 1 A left rail 3 is vertically fixed to the crossbeam 2, and a right rail 4 is provided at one end of the left rail 3. There is a gap between the left rail 3 and the right rail 4, and the side of the left rail 3 closest to the right rail 4 is arranged in an arc shape, as is the side of the right rail 4 closest to the left rail 3. This not only increases the overall length of the rails, but also prevents the left rail 3 from obstructing the right rail 4 when it is folded, thus making the folding process of the right rail 4 smoother and reducing jamming.

[0033] Reference Figure 2 The cross-sections of both the left track 3 and the right track 4 are I-shaped, which improves the overall strength and stability of the tracks while reducing material usage and overall weight. The I-shaped design gives the tracks better bending resistance when subjected to external forces, thus ensuring the reliability of the beam structure during use. It also facilitates the sliding of lifting devices on the left track 3 and the right track 4.

[0034] Reference Figure 3 A mounting plate 9 is fixed on the right track 4. A T-slot 10 is formed on the mounting plate 9, and a T-block 11 that matches the T-slot 10 slides on the T-slot 10. The T-slot on the mounting plate 9 matches the T-block, which can accurately guide the linear movement of the T-block. A cylinder 5 is hinged to the crossbeam 2, and the piston rod of the cylinder 5 is hinged to the T-block 11.

[0035] Reference Figure 4 A support frame 6 is fixed on the left track 3, and the support frame 6 is arranged in an arc shape on the side near the right track 4. A pin 7 is fixed inside the support frame 6, and a rotating block 8 rotates on the pin 7. The rotating block 8 is fixedly connected to the right track 4.

[0036] The rotating block 8 can rotate freely around the pin 7, allowing the right track 4 to be easily rotated when the angle or position needs to be adjusted. Furthermore, the edges of the rotating block 8 are rounded, which effectively prevents collisions between the rotating block 8 and the receiving frame 6 during rotation, reducing mechanical wear and extending the service life of both the rotating block 8 and the receiving frame 6.

[0037] Reference Figure 2 and Figure 4Under normal conditions, the right track 4 and the left track 3 are aligned and on the same straight line, at which point the piston rod of cylinder 5 is fully extended to its maximum length. When it is necessary to fold the right track 4 during actual operation, cylinder 5 is activated, causing the piston rod to gradually retract. As the piston rod retracts, it drives the right track 4 to rotate clockwise around the pin 7 inside the receiving frame 6 via the rotating block 8; simultaneously, the piston rod of cylinder 5 is hinged to the T-block 11, allowing cylinder 5 to synchronously drive the T-block 11 to slide inside the T-slot 10, ultimately achieving the folding effect of the right track 4, reducing the space occupied by the beam frame when idle, and improving space utilization.

[0038] When the right track 4 needs to be unfolded during actual operation, cylinder 5 is activated, causing the piston rod to gradually extend. As the piston rod extends, it drives the right track 4 to rotate counterclockwise around the pin 7 inside the receiving frame 6 via the rotating block 8. At the same time, the piston rod of cylinder 5 is hinged to the T-block 11, so that cylinder 5 synchronously drives the T-block 11 to slide inside the T-slot 10, ultimately achieving the unfolding effect of the right track 4, increasing the overall length of the track for easier subsequent use.

[0039] Reference Figure 5 A pressure body 12 is provided on the receiving frame 6, and two bolts 13 are threadedly connected to the pressure body 12. The pressure body 12 and the receiving frame 6 are fixed by the two bolts 13. The threaded connection between the pressure body 12 and the receiving frame 6 by the two bolts 13 facilitates installation and disassembly. When the equipment is maintained, repaired or parts are replaced, the pressure body 12 can be quickly removed for convenient operation.

[0040] The implementation principle of the foldable beam frame structure for the fastener center in this application embodiment is as follows: When the right track 4 needs to be folded, the operator activates the cylinder 5. The cylinder 5 drives the piston rod to retract, causing the rotating block 8 to rotate clockwise around the pin 7. At the same time, the retraction of the piston rod causes the T-shaped block 11 to slide inside the T-shaped groove 10, ultimately achieving the folding effect of the right track 4. When the right track 4 needs to be unfolded, the operator activates the cylinder 5. The cylinder 5 drives the piston rod to extend, causing the rotating block 8 to rotate counterclockwise around the pin 7. At the same time, the extension of the piston rod causes the T-shaped block 11 to slide inside the T-shaped groove 10, ultimately achieving the unfolding effect of the right track 4.
