[0033] The terms "first", "second" are only for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the technical features indicated. Therefore, the features defined with "first", "second" can explicitly or implicitly include one or more of the features. In the description of the present application, unless otherwise stated, the meaning of "a plurality of" is two or more.

[0034] As shown in the figure, the guide and guard cross beam of the present application at least includes: guide and guard frame 1, cross beam 2, pressing plate 3, locking slide 4, locking screw 5, nut sleeve 1 6, combined spherical pad 1 7, combined spherical pad 2 8, screw rod 9, nut sleeve 2 10, pressing plate screw 1 1, guide and guard 1 2, etc.

[0035] 1. The guide and guard frame 1 is a welded frame structure, the inner side of the upper two sides is provided with a cross beam sliding groove for installing and adjusting the height position of the cross beam, and the opening size of the cross beam sliding groove is L1. Two lifting lugs are arranged on the upper cross beam of the guide and guard frame for connecting and installing the screw rod 9.

[0036] 2. The cross beam 2 is a welded piece, the width is L2, and locking wedge surfaces and screw rod 9 connecting and installing holes are arranged on the two sides respectively. Two L-shaped plates are symmetrically arranged on the cross beam 2, the inner and outer groove widths are inconsistent, forming a "convex" groove, the outer groove width is D, the inner groove width is E, and the two sides of the L-shaped plate are open.

[0037] ​3. The cross-sectional shape of the locking slider 4 is a right trapezoid, the oblique edge waist is a locking wedge surface, and the upper and lower bases are provided with through-length threaded holes for adjusting the position.

[0038] 4. The nut sleeve one 6 and the nut sleeve two 10 are nut welded parts, and the external sleeve can effectively protect the threaded connection and prevent the invasion of dust, iron oxide scale and water.

[0039] 5. The fixing principle of the cross beam 2 is as follows:

[0040] The cross beam 2 is fixed and locked in the cross beam sliding groove of the guide frame 1 through the locking slider 4, and is further connected to the lifting lug of the guide frame 1 through the screw rod 9. The screw rod 9 is installed in the threaded hole of the cross beam 2 at the lower part, and is fastened through the nut sleeve one 6 at the upper part.

[0041] The combined spherical pad one 7 and the combined spherical pad two 8 are respectively arranged above and below the lifting lug, which plays a buffering protection role when the cross beam 2 and the screw rod 9 are impacted.

[0042] Position adjustment of the cross beam 2:

[0043] When the height position of the cross beam 2 needs to be adjusted, the locking screw 5 is counterclockwise rotated to move the locking slider 4 inward to the middle to disengage the wedge surface of the locking slider 4 from the wedge surface on the cross beam 2, and after a gap is generated between the two wedge surfaces, the nut below the combined spherical pad two 8 is loosened, and the nut sleeve one 6 is rotated to adjust the height position of the cross beam 2.

[0044] After the position is adjusted, the locking screw 5 is clockwise rotated to move the locking slider 4 outward to the side to make the wedge surface of the locking slider 4 fit the wedge surface on the cross beam 2 without gap, at this time, the large bottom surface of the wedge block 4 should have a gap with the opening surface in the cross beam sliding groove to ensure that the wedge surfaces are fitted and locked.

[0045] 6. The press plate screw 11 is a full-thread hexagonal head bolt, the threaded diameter is d, the bolt head opposite side size is e, and the maximum outer dimension is s. Among them, D is slightly larger than d, E is slightly larger than e, and E is smaller than s.

[0046] The process of installing the press plate 3 is as follows: after the hexagonal bolt head of the press plate screw 11 is adjusted to the opposite side horizontal position, it is slid into the "convex" groove from the two sides of the L-shaped plate on the cross beam 2, the position of the press plate screw 11 is adjusted according to the position, then the press plate 3 is sleeved into the screw 11, the gasket and the nut sleeve two 10 are installed, and since E is smaller than s, the press plate screw 11 will not rotate during the tightening process of the nut sleeve two 10.

[0047] In the description of the application, it is necessary to point out that, unless otherwise explicitly specified and limited, the terms "mounting", "connection", "linking" should be understood in a broad sense, for example, can be fixed connection, can also be detachable connection, or integrally connected; can be directly connected, or indirectly connected through intermediate medium, can be the communication inside two elements. For those skilled in the art, the specific meaning of the above terms in the application can be understood according to the specific circumstances.

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