[0002] In the installation of hoisting equipment, especially in the installation of hoisting equipment in large industrial plants, the installation of hoisting crane is an important engineering content. Due to the heavy weight of hoisting crane and high installation accuracy requirements, it is necessary to Take measures to fix, generally adopt the method of plugging hard objects, although this method is simple, convenient and fast, but the reliability of the fixing effect is not high, resulting in large installation deviation, especially the considerable safety risk, the driving roller frame is easy to slip, easy to Cause safety accidents, which is not conducive to the safety management of the construction site
[0003] Therefore, there are above-mentioned inconveniences and problems in the known lifting and traveling roller frame installation and fixing method.

Embodiment 1
[0028] The installation and fixing method of the crane traveling roller frame of the present invention comprises the following steps:
[0029] see now figure 1 , figure 1 It is a structural schematic diagram of a gantry clamp according to an embodiment of the present invention.
[0030] a. Manufacture portal frame fixture: Cut three steel plates with a thickness of 20 mm, a length of 150 mm, and a width of 150 mm. One top plate 1 and two side plates 2 are combined and welded to form a door shape. Holes of 25 mm are opened on both sides to the middle and bottom of the outer side of the plate. Weld the nut 5 of the 22mm bolt outside the through hole 4, and install the 22mm screw rod 6 on the nut to pass through the 25mm hole.
[0031] b. Make the fixed fixture baffle 3: Cut a steel plate with a thickness of 10mm, a length of 300mm, and a width of 150mm, make an arc cut along the diagonal according to the radius of the crane rail wheel, and then cut a gap of 150mm in length and...

The invention provides a mounting and fixing method for a roller carrier of a crane trolley. The mounting and fixing method is characterized by comprising the following steps that a, a plurality of portal frame fixtures are manufactured; b, a fixing fixture is mounted; c, a temporary portal supporting frame is welded; d, a trolley roller carrier is mounted; and e, the portal frame fixtures are dismounted and repeatedly utilized, specifically, the trolley roller carrier is mounted well, a trolley large beam is mounted, after mounting of the trolley large beam and auxiliary components is completed, a wrench is adopted to loosen threaded rods (6) of the portal frame fixtures, and then the portal frame fixtures are dismounted and used for mounting a next crane trolley. The mounting and fixing method for the roller carrier of the crane trolley has the advantages that the portal frame fixtures and the portal supporting frame are simple in structure and convenient to manufacture, so that the trolley frame cannot slide, precise adjustment in the mounting process is facilitated, the mounting precision is improved, it is ensured that trolley rollers do not slide, so that safe construction in the mounting process is ensured, the safety risks are reduced, and the portal frame fixtures and the portal supporting frame can be repeatedly utilized and the construction cost is saved.
