The utility model is used for solving the problems that the manual fixing nut is easy to hurt fingers of personnel, has larger potential safety hazard and the bolt cannot be fastened to the standard moment.

Description

Mounting tool for door bolt of hydroelectric generating set

Technical Field

The utility model relates to a mounting tool for a door bolt of a hydroelectric generating set.

Background

In the shutdown maintenance process of the hydroelectric generating set, a set entrance door can be opened to enter the interior of the set for inspection and maintenance, the entrance door is closed after the maintenance is completed, in the process of installing bolts (M24), one maintenance person uses an electric spanner to fasten the bolts, and the other maintenance person uses an opening spanner to fix nuts, so that the nuts are prevented from rotating along with the bolts in the fastening process, the bolts are not completely fastened in place, and hidden danger is brought to the safe and stable operation of the subsequent set. The use of manual fixing nuts prevents following the rotation of the bolt during the bolt tightening process has two problems: 1. when the nut is fixed by manually holding the handle of the open spanner, the impact force of the electric spanner is too large, so that the manpower cannot be overcome, the ideal effect cannot be achieved, and on the other hand, when the position is narrow and the manpower cannot overcome the impact force, the fingers of the personnel are clamped and scratched due to the follow rotation of the arm, so that the potential safety hazard is large; 2. because the space around the entrance door is narrow, the open spanner with the common length handle can not be put in place, so that the open spanner can not be used, if the open spanner is used, an maintainer can not fully grip the handle part, the problem that the nut follows the rotation of the bolt still exists, and the bolt can not be fastened to the standard moment.

Disclosure of Invention

The utility model aims to solve the technical problem of providing a mounting tool for a man door bolt of a water turbine generator set, which is used for solving the problems that a man power fixing nut is easy to hurt fingers of a man, and has larger potential safety hazard and the bolt cannot be fastened to a standard moment.

In order to solve the problems, the technical scheme of the utility model is as follows:

the utility model provides a hydroelectric set people door bolt mounting tool, includes the supporting shoe, supporting shoe both ends fixed connection clamp splice, and the breach has been seted up to the clamp splice upper end, and threaded connection has the screw rod on the clamp splice, and screw rod one end is located the breach, has seted up the through-hole that is used for inserting the spanner on the supporting shoe.

The notch is internally provided with a jacking block, the jacking block is provided with a stepped hole, and an internal screw arranged in the stepped hole is connected with the screw rod.

One end of the screw rod outside the notch is provided with a handle.

The beneficial effects of the utility model are as follows:

1) The manual fixing of the screw cap is not needed any more, and the risk of injury is effectively reduced compared with the traditional mode.

2) Because the field operation space is narrow, two people are needed to work cooperatively at present, and the work can be completed by one person independently through the tool, so that the working efficiency is improved, and the human resource cost is reduced.

3) The tool replaces the manual fixing nut with the fixing nut, so that the bolt can be fastened to the standard moment, mechanical damage possibly caused by the manual fixing nut is avoided, and the safety risk is reduced.

Drawings

The utility model is further described with reference to the accompanying drawings:

figure 1 is a schematic view of the structure of the present utility model,

figure 2 is a schematic view of a partial cross-sectional structure of the present utility model,

fig. 3 is a schematic structural view of the present utility model in practice.

In the figure: wrench 1, supporting block 2, clamp splice 3, breach 4, kicking block 5, screw rod 6, handle 7, screw 8, people's door 9, electronic spanner 10.

Detailed Description

As shown in fig. 1 to 3, a mounting tool for a door bolt of a water turbine generator set comprises an arc-shaped supporting block 2, wherein the radian of the supporting block 2 is consistent with the shape of a door, two ends of the supporting block 2 are fixedly connected with clamping blocks 3, gaps 4 are formed in the upper ends of the clamping blocks 3, a screw rod 6 is connected to the clamping blocks 3 in a threaded manner, one end of the screw rod 6 is located in the gaps 4, through holes are formed in the supporting block 2, and a wrench 1 is inserted into each through hole.

As shown in fig. 2, a top block 5 is arranged in the notch 4, a stepped hole is arranged on the top block 5, and an inner hexagon screw 8 arranged in the stepped hole is connected with the screw rod 6. The contact area between the top block 5 and the door is enlarged, and the clamping effect of the installation tool is improved.

The end of the screw rod 6 outside the notch 4 is provided with a handle 7. The handle 7 facilitates the screwing of the screw 6 by the staff.

As shown in fig. 3, when in use, a worker firstly initially fastens the screw bolt of the door 9 to prevent the screw bolt from shaking, the screw bolt is not fastened in place at the moment, then a spanner 1 in the installation tool clamps the screw cap to clamp the edge of the door 9 into the notch 4, and rotates the screw rod 6 to tightly cling the top block 5 to the door 9, so that the installation tool is completely fixed on the door 9, the spanner 1 fixes the screw cap, and finally the worker fastens the screw cap by using the electric spanner 10.
