Detailed Description
In order to better understand the purpose, structure and function of the present invention, the following description is made in detail with reference to the accompanying drawings.
As shown in fig. 1 and 2, a novel portable main shaft fixing and adjusting device is used for leveling and fixing a main shaft when a bearing box is replaced in the overhaul of a main ventilator, and comprises an adjusting block 1, wherein one side of the adjusting block 1 is a first connecting part 11, the first connecting part 11 is connected with one end of a first supporting rod 2, the other end of the first supporting rod 2 is connected with a first jacking support 3 used for supporting a main shaft of the main ventilator, the other side of the adjusting block 1 is a second connecting part 12, the second connecting part 12 is connected with one end of a second supporting rod 4, the other end of the second supporting rod 4 is connected with a second jacking support 5 used for supporting the inner wall of the main ventilator, and the adjusting block 1 can be rotated to enable the first jacking support 3 and the second jacking support 5 to be close to or far away from each other. The device is simple in structure, easy to operate and convenient to use, and the telescopic amount of the device can be adjusted by rotating the adjusting block 1, so that the main shaft is fixed.
In this embodiment, the main shaft fixing and adjusting device is made by welding a screw rod, a nut and steel plates, the adjusting block 1 comprises two steel plates which are symmetrically arranged, the welding nuts at two ends of the steel plates form a first connecting part 11 and a second connecting part 12 respectively, a through groove 13 formed between the two steel plates can be inserted into a lever for fastening or unloading after completion, the nuts at two sides are respectively screwed with screw rods with opposite screw threads, and therefore the adjusting block 1 is rotated to enable the jacking supports at the outer sides of the screw rods at two sides to be close to or far away from each other.
In an alternative embodiment, one side of the adjusting block 1 is screwed with the supporting rod, the other side of the adjusting block is fixedly connected with the supporting rod, and the fixedly connected supporting rod and the jacking block rotate together with the adjusting block 1. Preferably, one side spiro union bracing piece of adjusting block 1, the bracing piece is rotatably connected to the opposite side, swivelling joint's bracing piece and top support can keep with the bracing piece relatively fixed of spiro union, can set up the connecting axle between adjusting block 1 and bracing piece, or set up the jack in adjusting block 1 and make the bracing piece that penetrates rotatable mode realization such as rotatable connect.
In an alternative embodiment, the first jacking 3 is an arc-shaped plate, and the arc-shaped plate is in contact with the main shaft surface of the main ventilator; the second top support 5 is an arc-shaped plate, and the arc-shaped plate is in contact with the inner wall surface of the main ventilator. This type of support is safer and more reliable, but requires that the first top support 3 and the second top support 5 cannot rotate with the adjusting block 1.
When the main ventilator is overhauled and the bearing box is replaced, three sets of the device are used for respectively and fixedly supporting the left side, the right side and the lower side of the main shaft, and the telescopic amount is adjusted by rotating the adjusting block 1, so that the purpose of leveling and aligning the main shaft is achieved. In addition, the device can be used for effectively supporting and fixing the main shaft, and then the bearing box is replaced, so that the process of leveling and aligning again during installation can be omitted, and the overhaul progress is further accelerated.
It is to be understood that the present invention has been described with reference to certain embodiments, and that various changes or equivalents may be substituted for elements thereof by those skilled in the art without departing from the spirit and scope of the invention.
