Problems solved by technology

[0003] Many deficiencies were found in the actual operation of the original process, such as the steel wire drawing method in the process, the number of steel wires is large and each steel wire must be measured and adjusted to the theoretical position, the progress of steel wire drawing is slow, and the measurement accuracy of steel wire is not high
The wire drawing method to measure the thickness of the gasket is to measure a data at each gasket to determine the thickness of the gasket. The data measured by this method has certain disadvantages. For the guide rail base that is inclined to the inside, after processing according to the slope requirements of the drawing, Welded shims may not be able to tilt outward, which will affect the installation of the shims
There is no horizontal requirement for the bottom support of the guide rail. If the bottom support is not positioned according to the horizontal position on site, the hoisted guide rail will be in a relatively large inclined state, which greatly increases the adjustment workload in the later stage

Embodiment 1

[0046] This embodiment provides an installation and adjustment device for a vertical guide rail of an elevator, which includes two installation and adjustment mechanisms used in conjunction with each other, and the installation and adjustment mechanisms are symmetrically arranged on both sides of the vertical guide rail. The installation adjustment mechanism includes a U-shaped bottom plate 1, a fixing bolt 2, a support plate 3, a first adjustment mechanism, and a second adjustment mechanism.

[0047] The width of the slot of the U-shaped bottom plate 1 is greater than the thickness of the base panel of the installation base, and a bolt mounting hole is provided through the side wall of the U-shaped bottom plate 1, and the fixing bolt 2 is installed in the bolt mounting hole. The U-shaped bottom plate 1 and the fixing bolts 2 form the bottom fixing mechanism. The U-shaped bottom plate 1 is clamped on the base panel of the vertical guide rail, and the U-shaped bottom plate 1 can...

Embodiment 2

[0059] This embodiment provides a method for installing a vertical guide rail of a ship lift, which includes the following steps:

[0060] Step 1. Make the bottom support. The bottom support includes an upper plate 8 and an adjustable column 9. The upper plate 8 is a steel plate with a thickness of 50mm planed on the upper surface by a planer. There are 4 adjustable columns, and the adjustable column 9 is used for Support the upper plate 8, adjust the levelness of the upper plate 8 and the distance between the upper plate 8 and the deck to the theoretical value required by the drawing, and then adjust the bottom adjustable column 9 with the help of a spirit level to adjust the upper plate 8 supported by the bottom to level. Fix by spot welding after adjustment.

[0061] Step 2. According to the Yang Chong mark point on the center line of the lift platform body, draw the platform cross center line on the lift platform body. The platform cross center line includes the platform h...

Abstract

The invention discloses an installation method of a vertical guide rail of a ship elevator. The installation method comprises the following steps that 1, a bottom support is manufactured; 2, a cross center line of a flat plate is marked on the bottom support; 3, each section of a vertical guide rail is sequentially hoisted in place from bottom to top; 4, adjusting is carried out on the vertical guide rail through an adjusting device, so that the corresponding faces of all sections of the guide rail are kept aligned; 5, total thickness measuring is carried out on a welding gasket and an adjusting gasket by using a caliper; 6, after thickness measuring of the gaskets is finished, the welding gasket is installed; 7, the vertical guide rail is hoisted back from bottom to top according to the serial number, the thickness of the adjusting gasket is adjusted through the caliper, spot welding is conducted on the adjusting gasket installed in place, and a fastening bolt is installed; and 8, positioning pins and set screws are installed, and a base plate between the adjusting device and the vertical guide rail is dismantled. The method can be operated without special training, extra cost isnot needed, and the training and operation cost is almost zero.

Description

technical field [0001] The invention belongs to the field of shipbuilding, and in particular relates to a method for installing a vertical guide rail of a ship lift. Background technique [0002] The guide rail of the elevator is a device that fixes and guides the movement of the lifting platform. It is the key to ensure the precise linear motion of the lifting platform under high load conditions. The installation accuracy of the guide rail is high. Our country started late in the installation and application of elevators, and there is a certain gap with foreign advanced technologies, and there is still a large room for development. The guide rails of the elevator in the ship are divided into two rows. Each row of guide rails consists of upper, middle and lower sections. Each row of guide rails has two horizontal and vertical guide surfaces. In order to ensure its good guiding effect, the installation requirements for the elevator guide Higher, it is required that the paral...
