Description

Technical Field

[0001] The present invention relates to the technical field of beam bodies, and more particularly to a hanger beam. Background Art

[0002] The monorail hoisting frame beam is a vertically loaded slender beam. It uses its own mechanical strength to achieve the key component of adjusting the center of gravity and gravity load distribution of large-tonnage materials to be transported. It has a wide range of uses. The monorail crane locomotive is an important auxiliary transportation machinery in coal mines. It is widely used in narrow spaces such as tunnels and mines. It can move along the track suspended above the tunnel or mine. It has the advantages of flexible transportation, small space occupation, and high transportation efficiency.

[0003] The monorail crane realizes the function of transferring and transporting materials to be transported under the lifting and bearing of the lifting beam. However, in the prior art, the supporting hanger beam of the lifting beam usually adopts a box-type structure. The hanger beam directly bears the deadweight of the large tonnage of materials to be transported through a circular chain. Since the monorail crane runs on a large track with many curves, the locomotive is often stuck and vibrated due to the ups and downs of the track, causing the lifting frame beam to bend and deform, and the weld to crack, resulting in the hanger beam having a large design size, heavy deadweight, and difficulty in reloading and transporting it down the shaft, which affects the use of the lifting beam.

[0004] In summary, how to effectively solve the problem that the current hanger beam cannot be easily transported and its bearing strength cannot be guaranteed at the same time is an issue that technical personnel in this field urgently need to solve. Summary of the invention

In addition, cables are used between adjacent segmented beams to withstand the tension in the extension direction of the segmented beams through the cables, which greatly strengthens the torque transmission between the segmented beams, so that after the main body of the beam is disassembled, the overall torque resistance can meet the use requirements. In summary, this hanger beam can effectively solve the problem that the current hanger beam cannot guarantee the convenience of transportation and the bearing strength at the same time.

[0025] The embodiment of the invention discloses a hanger beam, which effectively solves the problem that the existing hanger beam cannot ensure convenient transportation and bearing strength at the same time.

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] See also Figure 1-Figure 4 , Figure 1 A schematic diagram of the main structure of a hanger beam provided in an embodiment of the present invention; Figure 2 A schematic diagram of a partial cross-sectional structure of an outer end of a segmented beam located at an end portion provided by an embodiment of the present invention; Figure 3 A schematic diagram of the outer end cable installation structure of a segmented beam at the end provided by an embodiment of the present invention; Figure 4 A schematic structural diagram of a segmented beam located in the middle provided in an embodiment of the present invention.

[0028] In a specific embodiment, this embodiment provides a hanger beam, which mainly includes a beam body and a cable 1.

[0029] The beam body refers to the main part of the hanger beam, that is, when only the beam body exists, it can still be called a hanger beam. The beam body is mainly a thicker rod, the cross section can be round, square or special-shaped, and the length is set according to the needs.

[0030] The beam body is separated into multiple segmented beams 2 along its own extension direction, that is, multiple segmented beams 2 are spliced ​​along the extension direction to form the beam body, which can be separated into two, three, four, etc., and can be specifically set as needed. The lengths of the segmented beams 2 can be the same or different, and the cross-sectional shapes can be the same or different, and can be set as needed.

[0031] The end faces of adjacent segmented beams 2 are fitted and the ends are fixedly connected by a detachable fixing device, so that the adjacent segmented beams 2 can be detached. The detachable fixing device can be a bolt 3, a screw, a riveted structure, a clamping structure, etc., or riveting. Specifically, the corresponding connection device can be selected according to the connection strength.

[0032] The cable 1 passes through at least one group of adjacent segmented beams 2 and its two ends are connected to two segmented beams 2 to prevent the adjacent segmented beams 2 from moving away from each other. The tension of the cable 1 pushes the end faces of the adjacent segmented beams 2 to fit closely together, so that the end faces fit closely together to transmit torque, and the cable 1 can more effectively prevent the adjacent segmented beams 2 from deflecting relative to each other, greatly improving the overall bending resistance of the beam body.

[0033] In the hanger beam, the main body of the beam is separated into multiple segmented beams 2 along the extension direction, so that they can be disassembled and stacked during transportation, which greatly reduces the transportation space requirements, and thus effectively facilitates transportation and reduces the difficulty of reloading and transporting the hanger beam down the mine. In addition, a cable 1 is used between adjacent segmented beams 2 to withstand the tension in the extension direction of the segmented beam 2 through the cable 1, which greatly strengthens the torque transmission between the segmented beams 2, so that after the main body of the beam is disassembled, the overall torque resistance can meet the use requirements. In summary, the hanger beam can effectively solve the problem that the current hanger beam cannot guarantee the convenience of transportation and the bearing strength at the same time.

[0034] Furthermore, in order to better transport the hanger beam and ensure its strength, the beam body preferably includes a box beam 4 and a hanging plate 5 arranged on the side of the box beam 4 and extending along the extension direction of the box beam 4, wherein the box cavity inside the box beam 4 is closed and provided with a nozzle 6 for injecting the filler. The box beam 4 is provided to facilitate lightweight configuration and better torque resistance, and the special hanging plate 5 is provided to facilitate the hanging of items.

[0035] Correspondingly, the internal box cavity of the box beam 4 is also closed and provided with a nozzle 6, so that a filler can be injected through the nozzle 6 later, and the entire hanger beam can be further strengthened through the filler. The solidified filler further forms a support in the box cavity to achieve a strengthening effect. It should be noted that the box cavity of the box beam 4 can be sealed according to the type of fluid filled, so that the filler injected from the nozzle 6 can be retained in the cavity of the box beam 4. Specifically, the filler can be concrete or other composite materials, such as plastic to be cured. Considering the fluid properties, in order to avoid the generation of bubbles inside the fluid solidification and the problem of poor fluid injection, the box cavity of the box beam 4 can also be away from the position of the nozzle 6, and an exhaust port can be provided. It should be noted that for the segmented beam 2, each segmented beam 2 can also include a box beam 4 part. At this time, the box cavities of adjacent segmented beams 2 can be connected or separated. If separated, some or each segmented beam 2 is correspondingly provided with a nozzle 6.

[0036] Furthermore, in order to facilitate the setting of the hanging plate 5 and to facilitate the hanging operation, it is preferred that the hanging plate 5 is provided with a through hole in the direction of the hole depth being the direction of the plate thickness, and a bushing 7 is provided in the through hole, wherein the bushing 7 is preferably a high-quality alloy steel bushing, and the specific bushing 7 and the hanging plate 5 can be welded and connected, or of course, can be connected by interference fit.

[0037] In order to ensure the connection strength, it is preferred that at least one side of the hanging plate 5 is connected to the box beam 4 by a plurality of rib plates 8. In order to ensure the strength, the hanging plate 5 is generally erected on the side of the box beam, and rib plates 8 are provided on both sides of the hanging plate 5 in the plate thickness direction. The rib plates 8 are right-angled, and the two straight edges of the rib plates 8 are respectively in contact with and connected to the hanging plate 5 and the rib plates 8, generally by welding.

[0038] Correspondingly, in order to facilitate hanging, it is preferred that hanging plates 5 are provided on both opposite sides of the box beam 4, wherein the hanging plates 5 are welded to the box beam 4. It should be noted that the hanging plates 5 may extend only on one segmented beam 2 or multiple segmented beams 2, or may extend on each segmented beam 2, and the hanging plates 5 on the corresponding side of adjacent segmented beams 2 are connected.

[0039] Furthermore, in order to better fit the adjacent segmented beams 2, it is preferred that the adjacent segmented beams 2 are positioned and contacted by matching concave and convex stoppers 9, that is, among the adjacent segmented beams 2, one segmented beam 2 has a concave stopper, and the other segmented beam 2 has a convex stopper matching the concave stopper, so that the adjacent segmented beams 2 can be prevented from lateral relative movement by the matching concave and convex stoppers 9. Correspondingly, the concave and convex stoppers 9 can also be used to prevent the adjacent segmented beams 2 from rotating around the axis extending in the direction in which the beam body extends, and specifically, the concave and convex stoppers 9 can be made square.

[0040] Specifically, the ends where adjacent segmented beams 2 are connected each have a rectangular plate, which is rectangular in shape. Along the length direction of the rectangular plate, the box beam 4 is located in the middle, and a hanging plate 5 is provided in the middle of both sides of the box beam 4. The four corners of the rectangular plate have through holes for bolts 3, and preferably each corner has two through holes for bolts 3 arranged in parallel along the length direction of the rectangular plate. The middle part of the rectangular plate in the length direction, specifically the part corresponding to the box beam 4, is provided with a concave and convex stopper 9 that passes through the width direction of the rectangular plate. Furthermore, the two ends or one end of the rectangular plate in the length direction can be further provided with a concave and convex stopper 9 extending in the length direction.

[0041] Furthermore, for the convenience of transportation, it is preferred that the beam body is separated into three segmented beams 2 along the extension direction, wherein the lengths of the three segmented beams 2 may be equal or unequal. Specifically, it is preferred that the length of the segmented beam 2 located in the middle is greater than that of the segmented beams 2 located at both ends, so that the middle portion can better withstand the moment. It should be noted that the outer ends of the segmented beams 2 located at both ends, i.e., the ends away from the middle segmented beam 2, have end plates for installing the ends of the cables 1.

[0042] Specifically, it is preferred that both ends of the cable 1 extend to both ends of the beam body and be restricted at the ends by cable clamping devices located at the end surfaces. The specific cable clamping device includes a cable clamping seat 10 fixed on the segmented beam 2 and a cable clamping piece 11 inserted into the cable clamping seat 10. The multiple cable clamping pieces 11 are petal-shaped, forming a conical column with a conical outer side surface. The thick end of the conical column faces the end of the cable 1, and the thin end faces the middle of the cable 1. The inner side of the conical column is clamped with the outer side of the cable 1 through matching annular protrusions and annular grooves to prevent relative movement along the extension direction of the cable 1. Specifically, the outer side of the cable 1 can have an annular groove, the inner side of the conical column can be clamped in the annular groove, or the inner side of the conical column can have an annular protrusion to be clamped in the annular groove, so that when the end of the cable 1 is forced to move toward the middle, because it is clamped with the conical column through the annular groove and the annular protrusion, the conical column is pushed to move toward the middle, and the conical outer wall of the conical column is against the cable clamping seat 10 to prevent the conical column from moving toward the middle of the cable 1, thereby achieving a limiting effect. Specifically, a conical column may be formed by three petal-shaped cable clamps.

[0043] Furthermore, in order to better protect the cable 1 and the corresponding cable clamping device, it is preferred that a protective cap 12 is provided at the end of the beam body, wherein the protective cap 12 is provided outside the end of the cable 1 and the cable clamping device. Specifically, a notch can be provided on one side of the outer end of the segmented beam 2 at the end, the cable clamping device is located at the notch, the protective cap 12 is provided at the notch, and the outer end is aligned with the end of the beam body.

[0044] Further, it is preferred that multiple cables 1 are arranged in parallel, specifically, three cables 1 are arranged in a herringbone shape, and are sequentially passed through each segmented beam 2, and the two ends are respectively located at the outer ends of the segmented beams 2 at both ends. The cables 1 are preferably steel strands, and of course, they can also be high-strength carbon fiber rods or carbon fiber wires.

[0045] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.
