Problems solved by technology

However, for the upside-down screw bolts, if they are moved and installed and aligned by lifting, the problem of interference between the lifting rope and the cylinder block will be involved. At present, there is no effective and suitable solution; Manually pushing and moving the way to move and install and align, there are technical problems of high labor intensity, low efficiency, and poor safety, and there is also an installation foundation with the steam turbine in the process of pushing and moving (see figure 1 Label 5) in the problem of interference, which will increase security risks
[0006] In summary, based on the particularity of heavy-duty upside-down wire bolts, the existing conventional bolt installation equipment and methods are difficult to meet the installation requirements of heavy-duty upside-down wire bolts, which directly increases the Technical difficulty of installation on equipment components

Embodiment 1

[0034] see figure 1 As shown, in the design structure of the steam turbine cylinder with horizontal tangential steam inlet valves on both sides of the cylinder, the steam turbine is arranged on the installation base 5; the steam inlets of the cylinder 4 on the installation base 5 are generally set to two, and the steam turbine on the cylinder Half 41 and cylinder lower half 42 are each provided with one. For the structure in which the steam inlet is located in the upper half 41 of the cylinder, there is an upside-down screw bolt 43 between the mid-section planes of the upper half 41 and the lower half 42 of the cylinder, based on which the upside-down screw bolt 43 is a typical heavy-duty bolt , its installation on the cylinder 4 requires the help of the following installation tools.

[0035] see figure 2 and image 3 As shown, the installation tools required for the installation of the above-mentioned heavy-duty upside-down bolts 43 on the cylinder 4 include a lifting fra...

Embodiment 2

[0052] In the design structure of the steam turbine cylinder with horizontal tangential steam inlet valves on both sides of the cylinder, the steam turbine is arranged on the installation base; the steam inlet of the cylinder on the installation base is generally set to two, the upper half of the cylinder and the lower half of the cylinder respectively. set one up. For the structure in which the steam inlet is located in the upper half of the cylinder, there is an upside-down screw bolt between the upper half of the cylinder and the mid-section of the lower half of the cylinder. The installation requires the help of the following installation tools.

[0053] The above-mentioned installation tools required for the installation of the above-mentioned heavy-duty upside-down bolts on the cylinder include lifting brackets, auxiliary bolts and wrenches.

[0054] Wherein, the lifting frame has a main girder, an auxiliary girder, a joint and a splint.

[0055] The main girder is a l...

Abstract

A heavy-type inverted studded thread bolt mounting tooling and a use method of same. The tooling includes: a sling frame, which is provided with a main beam, a sub-beam at one side of the main beam, ajoint which is arranged on the middle of the other side of the main beam and is extended, and a clamping plate arranged on the outer end of the joint. Sling holes, which are arranged in an isoscelestriangle shape, are formed in two ends of the main beam and the sub-beam. The top ends of the sling holes arranged in the isosceles triangle shape are located on the outer end of the sub-beam and arelocated at the extension line of the central line of the joint. A clamping thread hole, which is matched with the structure of a to-be-mounted inverted studded thread bolt, is formed on the outer endof the clamping plate. When the sling frame is under an idle or loaded status, the gravity of one side of the is larger than that of one side of the joint with the sling frame as the central line, sothat the sling gravity is located between the sling holes, which are arranged in an isosceles triangle shape, between the main beam and the sub-beam. The structure effectively overcomes position interference of a sling hoisting rope and corresponding equipment parts, and ensures that the inverted studded thread bolt can be maintained to be balanced, stable and safe during the slinging and moving processes.

Description

technical field [0001] The invention relates to a bolt installation tool, in particular to an installation tool for heavy-duty upside-down threaded bolts and a method for using the installation tool, which is particularly suitable for installation of upside-down threaded bolts at subplanes in steam turbine cylinders. Background technique [0002] The threaded bolt is a fastening joint that screw a threaded head of the screw rod into the threaded hole (usually a blind hole structure) of the equipment components to be fastened and connected, similar to "planting trees". [0003] According to its bottom-up wire installation on equipment parts, the wire bolts form an inverted wire structure - that is, inverted wire bolts, which are especially common in the combined connection of large equipment parts, such as in steam turbine cylinders In the faceted combination connection structure, the connection bolts used for the butt combination on large equipment parts are usually large in...
