Detailed Description

As shown in fig. 1-8, the bottom shaft of the gate is connected with a plurality of bottom supporting devices, each bottom supporting device comprises a half shaft bushing 1, a fixed seat 2 and a pair of pressing plates 3, the fixed seats 2 are all fixedly connected to the bottom, and the fixed seats 2 are detachably connected with a containing groove 20 with a semicircular cross section through bolts, the half shaft bushing 1 is in a semicircular cylinder shape matched with the bottom shaft 5 of the gate, and the bottom surface 1 of the half shaft bushing is attached to the containing groove 20;

the pressing plate 3 is in a long strip shape, the pair of pressing plates 3 are detachably connected to two sides of the top surface of the accommodating groove 20 through bolts, and the pair of pressing plates 3 are parallel to the half shaft bushing 1 and are respectively pressed on end surfaces of two sides of the half shaft bushing 1. During the use, can directly place the bottom shaft of gate in the semi-axis bush for through the design to the low coefficient of friction of semi-axis bush inner wall, keep slidable relation between bottom shaft and the semi-axis bush, and make through a counterpressure board and keep relative static between semi-axis bush and the storage tank, thereby realize the function of original bearing and bearing frame.

When the half axle bush reached life and need be changed, operating personnel changed the half axle bush in the end strutting arrangement one by one, and the change process of single half axle bush is: firstly, detaching a pair of pressure plates, rotating the gate by a certain angle by virtue of an original driving mechanism, keeping the gate in an inclined state (enough movable space is reserved for extruding the half shaft bushing), and then applying force from one side end surface of the half shaft bushing to extrude the half shaft bushing; after that, the operator can put the new half axle set into the fixed seat again, and install all the pressing plates again, accomplish the convenient change of half axle set. In the process, the gate is not required to be lifted by means of lifting equipment, the operation is very convenient and efficient, the operation time is short, and the potential safety hazard is low.

And a strip-shaped sealing cushion plate 30 is also arranged between the half shaft bushing 1 and the pressing plate 3. Therefore, the bolt for realizing the detachable connection of the pressure plate and the fixed seat and the half shaft bushing are protected to a certain extent, and the whole body has longer service life.

The underwater mounting groove that is equipped with, fixing base 2 includes fixed part 21 and a pair of side fixed part 22 down, fixed part 21 and a pair of side fixed part 22 are respectively through bolt detachable connection in the mounting groove down, the storage tank is connected with a pair of side fixed part detachable through the bolt. Therefore, the arrangement of the fixing seat is more convenient, and the installation difficulty and the operation time of the fixing seat are obviously reduced.

The optimized implementation mode of the scheme is that the half shaft bushing 1 is composed of a plurality of lining plates with arc-shaped sections, the lining plates are long-strip-shaped, and adjacent lining plates are attached to each other. Therefore, the half shaft bushing is designed into a split structure, so that the defects of high processing difficulty and high precision requirement in the integral processing of the half shaft bushing are avoided; on the other hand, when the half axle bush was changed, can put into new welt one by one between bottom shaft and the fixing base to extrude original welt one by one, thereby need not operations such as adjustment gate angle, the operation degree of difficulty when further having reduced the half axle bush and changing.

In addition, in order to enable the half shaft to be more conveniently extruded in a complete set, and the bottom shaft of the gate cannot accidentally descend in the extruding process, and the whole gate cannot incline, the scheme also discloses an auxiliary device, wherein the half shaft bushing 1 is extruded through the auxiliary device 4, the auxiliary device 4 comprises a plurality of rollers 41 and a plurality of pairs of hinge blocks 42, two ends of each roller 41 are provided with shaft heads 410, and the outer diameter of each roller 41 is equal to the wall thickness of the half shaft bushing 1;

the plurality of rollers 41 are arranged in parallel, a plurality of pairs of hinge blocks 42 are respectively hinged with shaft heads on two sides of each roller 41, and one hinge block 42 is hinged with two shaft heads on the same side of two adjacent rollers 41, so that the plurality of rollers 41 are kept connected. In this way, the rolling shafts can be put into the half shaft bushings one by one while the half shaft bushings are extruded, so that effective temporary support is carried out between the bottom shaft and the accommodating groove; when a new axle shaft bushing is installed, all rollers can be squeezed out with the new axle shaft bushing. Finally, when the number of the bottom supporting devices is small, the problems that the bottom shaft of the gate descends unexpectedly and the gate is integrally inclined before a new half shaft bushing is installed can be effectively avoided.
