Abstract

The utility model discloses a split frame for power generator, comprising a top frame and a bottom frame. One of the connecting pipes for the top and bottom frames is welded to a bayonet pipe for their connection. A plurality of bolt holes are arranged in this connecting part which is fixed with bolts in the holes. The bolt holes in the connecting part are provided with an included angle of 45 degree relative to the side face of the top or bottom frame so that the bolt head in the hole and nut end are beyond the frame set by the top and bottom frame. With the included angle of 45 degree between the bolt hole for connection and the side face, the bolt head in the hole and nut end are beyond the frame, which does not interfere with the parts in the frame nor requires the space for the operation of a spanner, thus facilitating the installation and connection of the top and bottom frames, and the maintenance and removal of the machine.

Description

Split type generator frame

Technical field

The utility model relates to a kind of generator frame, in particular for the split type frame of general small-size generator.

Technical background

The general small-size generator is generally in order to move conveniently, the assembly of whole generating machine all is installed in the frame that constitutes with pipe fitting, frame is integral frame shape, these shelfs often influence assembling, the repair demolition of generator, thereby in some cases because assembly technology needs, frame is manufactured split type, common split type frame is divided into puts on the shelf and undercarriage, connects into integral body with bolt after assembling is finished between upper and lower.The general small-size split generator frame of prior art, on, connect between the undercarriage is to utilize one of welding in the pipe of pipe connector up and down can insert latch pipe in the tube core of another root pipe, and process the bolt hole of pairing, assembling pairing back is integral with bolt, as shown in Figure 4, the direction of bolt hole is parallel to the side of frame, make bolt head or nut end that frame inside is again arranged on one side all the time like this, because the compactness of general small-size generator designs, entering the bolt head of frame inside or component that nut end often will influence generator inside installs, also influence maintenance simultaneously, dismounting, for example must stay enough spanner spaces, otherwise, or tight bolt difficulty when going up lower bearing bracket and connecting, the very many component of essential dismounting cause assembling when keeping in repair some positions, the inconvenience of maintenance.

The model utility content

The purpose of this utility model provides a kind of split type generator frame, overcomes the defective that above-mentioned prior art exists, convenient upper and lower frame connection, maintenance and dismounting.

A kind of split type generator frame described in the utility model, by put on the shelf, undercarriage forms, put on the shelf, undercarriage have respectively four vertical put on the shelf, the undercarriage connecting tube, every pair put on the shelf, one of undercarriage connecting tube is welded with the latch pipe, insert with the latch pipe each other and connect, go up or undercarriage connecting tube and latch pipe are processed with the bolt hole of level, and pass fixing with bolt, the bolt hole machine direction of connection part with put on the shelf or 45 ° of the side angles of undercarriage, the bolt head of the bolt that passes and nut end are in outside the determined framework of undercarriage.

Split type generator frame described in the utility model, because the bolt hole direction of connection part is processed into and puts on the shelf or the side angle of undercarriage is 45 °, the bolt head of the bolt that passes and nut end are in outside the determined framework of undercarriage, bolt head and nut end can not interfere with the component in the frame, simultaneously do not need to stay special spanner space, thereby made things convenient for upper and lower frame that maintenance, the dismounting of connection and machine are installed.

Description of drawings

Now in conjunction with the accompanying drawings the utility model is described in further detail.

Fig. 1 is the structural representation of split type generator frame described in the utility model (when last undercarriage is in separated state);

Fig. 2 is the left view of Fig. 1;

Fig. 3 for undercarriage on this generator frame connect the back in Fig. 2 the B-B place analyse and observe zoomed-in view;

Fig. 4 is the sectional structure schematic representation of prior art frame undercarriage connection part on it.

Embodiment

As shown in Figure 1-Figure 3, split type generator frame described in the utility model, by putting 1 on the shelf, undercarriage 2 is formed, put on the shelf 1 and undercarriage 24 put on the shelf connecting tube 3 and undercarriage connecting tubes 4 are arranged respectively separately, undercarriage connecting tube 4 is welded with a latch pipe 7, the latch pipe 7 of undercarriage connecting tube 4 inserts the interior connection each other of pipe of the connecting tube 3 of putting on the shelf, the connecting tube 3 of putting on the shelf is processed with bolt hole 5, the latch pipe 7 of undercarriage connecting tube 4 is processed with bolt hole 6, bolt 8 passes

bolt hole

5,6 and fixing with nut 9,

bolt hole

5,6 machine direction with put on the shelf or 45 ° of the side angles of undercarriage, make the bolt head and the nut end of the bolt 8 that passes be in undercarriage 1, outside the 2 determined frameworks, just be in outside the split type generator frame, bolt head and nut end can not interfere with the component in the frame.

Claims

1, a kind of split type generator frame, by put on the shelf (1), undercarriage (2) is formed, put on the shelf (1), undercarriage (2) has four vertical putting on the shelf respectively, undercarriage connecting tube (3,4), put on the shelf for every pair, undercarriage connecting tube (3,4) one of be welded with latch pipe (7), insert with latch pipe (7) each other and connect, go up or undercarriage connecting tube (3 or 4) and latch pipe (7) are processed with the bolt hole (5 of level, 6), and pass fixing with bolt (8), it is characterized in that: the bolt hole (5 of connection part, 6) machine direction with put on the shelf or 45 ° of the side angles of undercarriage, make the bolt head and the nut end of the bolt (8) that passes be in undercarriage (1,2) outside the determined framework.
