[0031] The embodiments of the present utility model will be described in detail below with reference to the accompanying drawings.

[0032] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present utility model.

[0033] The terms "first" and "second" are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present utility model, unless otherwise specified, the meaning of "plurality" is two or more.

[0034] As shown in the figure, a kind of guide beam of the present utility model at least includes: guide frame 1, crossbeam 2, pressing plate 3, locking slider 4, locking screw 5, nut sleeve one 6, combined spherical washer one 7, combined spherical washer two 8, screw rod 9, nut sleeve two 10, pressing plate screw 11, guide 12, etc.

[0035] 1. The guide frame 1 is a welded part of a frame structure, and crossbeam chutes are arranged on the inner sides of the upper two sides for installing and adjusting the height position of the crossbeam. The opening size in the crossbeam chute is L1. Two lifting lugs are arranged outside the upper crossbeam of the guide frame for installing and connecting the screw rod 9.

[0036] 2. The crossbeam 2 is a welded part, with a width of L2. Locking wedge surfaces and screw rod 9 connection and installation holes are respectively arranged on both sides. Two L-shaped plates are symmetrically arranged up and down in the middle of the crossbeam 2. The inner and outer groove widths are inconsistent, forming a "convex" groove. The outer groove width is D, and the inner groove width is E. Both sides of the L-shaped plate are open.

[0037] 3. The cross-sectional shape of the locking slider 4 is a right trapezoid, with the hypotenuse waist being the locking wedge surface, and through-thread holes are provided on the upper and lower bases for position adjustment.

[0038] 4. Both the nut sleeve one 6 and the nut sleeve two 10 are nut welded parts, and the outer sleeve can effectively protect the threaded connection and prevent the intrusion of dust, oxidized iron scale, and water.

[0039] 5. Fixing principle of the crossbeam 2:

[0040] The crossbeam 2 is fixedly locked in the crossbeam chute of the guard frame 1 through the locking slider 4, and is further connected to the lug of the guard frame 1 through the screw 9. The lower part of the screw 9 is installed in the threaded hole of the crossbeam 2, and the upper part is fastened through the nut sleeve one 6.

[0041] The combined spherical pad one 7 and the combined spherical pad two 8 are respectively arranged above and below the lug, which play a buffering and protective role when the crossbeam 2 and the screw 9 are impacted.

[0042] Position adjustment of the crossbeam 2:

[0043] When the height position of the crossbeam 2 needs to be adjusted, turn the locking screw 5 counterclockwise to horizontally move the locking slider 4 inward to the middle until the wedge surface of the locking slider 4 is separated from the upper wedge surface of the crossbeam 2. After a gap is generated between the two wedge surfaces, loosen the nut under the combined spherical pad two 8, and turn the nut sleeve one 6 to adjust the height position of the crossbeam 2.

[0044] After adjusting the position, turn the locking screw 5 clockwise to horizontally move the locking slider 4 outward until the wedge surface of the locking slider 4 fits seamlessly with the upper wedge surface of the crossbeam 2. At this time, there should be a gap between the large bottom surface of the wedge block 4 and the opening surface in the crossbeam chute to ensure the tight fit of the wedge surface.

[0045] 6. The pressing plate screw 11 is a full-thread hexagonal head bolt, with a thread diameter of d, a size across flats of the bolt head of e, and a maximum outer dimension of s. Among them, D is slightly larger than d, E is slightly larger than e, and E is less than s.

[0046] Process of installing the pressing plate 3: After adjusting the hexagonal bolt head of the pressing plate screw 11 to the horizontal position across flats, slide it into the "convex" groove from both sides of the L-shaped plate on the crossbeam 2. Adjust the position of the pressing plate screw 11 according to the position requirement, then put the pressing plate 3 on the screw 11, install the gasket and the nut sleeve two 10. Since E is less than s, the pressing plate screw 11 will not rotate during the tightening process of the nut sleeve two 10.

[0047] In the description of the present utility model, it should be noted that unless otherwise clearly specified and defined, the terms "installation", "connection", and "coupling" shall be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a direct connection, or an indirect connection through an intermediate medium, and it may be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0048] In the description of this specification, the specific features, structures, materials, or characteristics may be combined in a suitable manner in any one or more embodiments or examples.

[0049] As mentioned above, it is only the specific implementation manners of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model can easily think of changes or substitutions, which should all be covered within the protection scope of the present utility model.
