DETAILED DESCRIPTION

[0032] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0033] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as limiting the present invention.

[0034] Reference Figure 1-15 The present invention provides an integral crossbeam, comprising a crossbeam 1, wherein the middle portion of the crossbeam 1 protrudes toward both sides, a hollow recessed hole 102 is provided in the middle portion of the crossbeam 1, two limiting grooves 101 are provided at each end of the crossbeam 1, and a positioning pin 103 is inserted into the recessed hole 102 at the end of the crossbeam 1. A positioning pin 103 is also inserted into the interior of the recessed hole 102.

[0035] The crossbeam 1 is made of high-strength aluminum alloy and is manufactured into a double-box structural beam using a high-pressure one-piece extrusion process. The middle position of the crossbeam protrudes to both sides, thereby forming a concave hole 102 with both ends passing through the middle position of the crossbeam; two limit grooves 101 are provided at both ends of the crossbeam 1, and are symmetrically distributed on the upper and lower sides of the concave hole 102.

[0036] The crossbeam 1 of the present invention has a weight of only 40-50% of that of a conventional split crossbeam of the same length while ensuring strength, thereby reducing the labor intensity of the operator to the greatest extent.

[0037] The present invention also proposes: a beam bracket, each beam bracket includes two beams 1, and the two beams 1 are distributed up and down, and a connecting rod 2 is installed at both ends of the two beams 1. Connectors 3 are installed at the upper and lower ends of the connecting rod 2 respectively, and the connectors 3 are correspondingly arranged in the concave hole 102 at the end of the beam 1, and the end of the connecting rod 2 matches the limit groove 101 at the end of the beam 1.

[0038] In the present invention, the connecting rod 2 includes a multi-strand carbon fiber rope 201, the outer side of the multi-strand carbon fiber rope 201 is provided with a polyurethane coating layer 202, and a sheave 203 is installed at both ends of the multi-strand carbon fiber rope 201, and an axial hole 204 is opened in the middle of the sheave 203;

[0039] The connector 3 includes an eccentric shaft 302, which is rotatably mounted on the groove wheel 203 through the shaft hole 204. Square plates 301 are installed at both ends of the eccentric shaft 302. The fixed points of the ends of the eccentric shaft 302 and the square plates 301 deviate from the center point of the square plates 301. Marks 304 are provided on the edges of the square plates 301 near their four corners, and the distances between the four marks 304 and the axis of the eccentric shaft 302 are not equal.

[0040] A limiting pin 303 is provided on the side of the square plate 301 , and the square plate 301 is mounted on the eccentric shaft 302 via the limiting pin 303 .

[0041] like Figure 2 As shown, each set of beam supports includes two beams 1 distributed vertically. The beam supports are assembled through connecting rods 2 and connectors 3 provided at both ends of the beams 1. The ends of the connecting rods 2 and the connectors 3 are rotatable.

[0042] An eccentric shaft is installed between the two square plates 301 in the connector 3. Figure 12 As shown in the figure, when the square plate 301 and the eccentric shaft 302 are rotated, the distance between the square plate 301 on the upper side and the square plate 301 on the lower side of the connecting rod 2 can be adjusted while the overall length of the connecting rod 2 remains unchanged. Therefore, when the distance between the upper and lower cross beams 1 changes, the upper and lower cross beams 1 can also be assembled through the connecting rod 2 and the connector 3, and the positioning pins 103 are used to limit them, so that a stable cross beam bracket is formed.

[0043] The connecting rod 2 used in the present invention is not only high in strength, but also weighs only 15-20% of the weight of a traditional stud bolt, thereby reducing the labor intensity of the operator.

[0044] Reference Figure 13-15 , the connecting rod 2 and the connector 3 can be connected with one of the beams 1 ( Figure 13 The upper middle beam 1) is separated and then stored in another beam 1 ( Figure 14 After being received in the recessed hole 102 of the crossbeam 1) on the middle and lower side, it can be fixed in position by the positioning pin 103.

[0045] The present invention also proposes a crossbeam pressure-bearing fixture system comprising a plurality of transversely distributed crossbeam supports, which are laterally connected by connecting blocks 7. Adjacent crossbeams 1 at the same height are connected to the connecting blocks 7 via splicing grooves. The exterior surfaces of the crossbeams 1 are provided with splicing grooves that match the connecting blocks 7. The connecting blocks 7 can slide within the splicing grooves, adjusting their position relative to the crossbeams 1, thereby assembling the multiple crossbeam supports into various configurations.

[0046] According to actual operation requirements, whether a gap is left between two adjacent beams 1 can be determined by designing the external dimensions of the connecting block 7 .

[0047] The interior of the connecting block 7 may be provided with a cavity, and a reinforcing rib (not shown) may be provided in the cavity to ensure strength while reducing the deadweight of the connecting block 7. In addition, the connecting block 7 may also be in the form of a solid block, and the specific dimensions of the connecting block 7 may be designed as required.

[0048] The setting of the connecting block 7 can prevent the crossbeam 1 or the connecting rod 2 from being ejected due to accidental breakage. Therefore, the connecting block 7 acts like a safety device, effectively avoiding personal injury to the operator caused by equipment failure and improving the safety of the equipment during use.

[0049] like Figure 6 As shown, the four crossbeam supports are assembled transversely through the connecting block 7, and the crossbeam pressure fixing frame system formed after assembly can be pressurized and bonded to the conveyor belt 4.

[0050] The two sections of conveyor belt 4 are connected according to Figure 6 The form shown in is placed between the upper and lower beams 1, and the conveyor belts 4 are glued together using a heating plate 6, a cooling plate 61 and a pressurized pressure bag 5. The adhesive is covered to the joint, and then the pressure bag 5 is pressed to press the conveyor belts 4 together, and the heating plate 6 is provided for heating. In order to achieve the vulcanization effect, the temperature and pressure are maintained for a period of time to complete the splicing of the conveyor belts 4.

[0051] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
