As shown in fig. 3, each wire rope 94 has two guide wheels 93 equidistantly distributed along the vertical line of the wire rope, and the guide wheels 93 are positioned on the top of the arch cabinet and fixedly connected to the top of the arch cabinet through a fixing bracket 96, and mainly play a role in supporting, guiding and positioning the wire rope. As shown in fig. 5, the conventional guide wheel 93 is composed of a bearing seat 931, a shaft 932, a pulley 933, a set screw 934, etc., and the bearing seat 931 is a sliding bearing with a lining, i.e., a bearing seat housing 9311, a lining shaft sleeve 9312 and a shaft sleeve 9312 connected to the shaft 932 are provided on the outside. The existing guide wheel structure has the problems that the steel wire rope 94 inevitably deflects in operation, the transverse force generated by the steel wire rope 94 on the pulley 933 causes the pulley 933 to drive the shaft 932 to transversely deviate, and the shaft fleeing phenomenon can occur after a long time. In addition, in the installation process, the two guide wheels 93 on the same steel wire rope are very difficult to install and align, a certain degree of installation deviation exists inevitably, the steel wire rope 94 generates an eccentric force action on the pulley 933, so that the friction force between the steel wire rope 94 and the guide wheels 93 is increased, the abrasion of the steel wire rope 94 or the guide wheels 93 is accelerated, and the service life of the steel wire rope 94 or the guide wheels 93 is influenced.
In view of the above, the inventor provides a guide wheel of a gas tank leveling device, which is convenient to install and construct and has a better use effect, by means of years of related design and manufacturing experiences, so as to overcome the defects in the prior art.
SUMMERY OF THE UTILITY MODEL
