Abstract

The present invention discloses a process for installing large engineering components based on an SPMT vehicle group and its auxiliary installation structure. The process first sets embedded parts in the slope area where the large engineering components to be installed are located, and fixes wedge plates on the embedded parts to assist in leveling supporting circular tubes. Then, supporting circular tubes are loaded on the SPMT vehicle group and the large engineering components to be installed are fixed on them and lifted into place. Then, multiple sets of auxiliary supporting circular tubes are installed on the bottom side of the large engineering components. Then, the supported large engineering components are translated to the side of the slope for translation relay preparation, and the SPMT vehicle group reserved in the slope area is also loaded with supporting circular tubes to start sliding relay. The present invention utilizes the horizontal mode of the SPMT vehicle group and adopts the mutual cooperation of multiple points of support of the SPMT vehicle group to achieve horizontal relay of the large engineering components to be installed between the road surface and the slope by mutual force. When the large engineering components to be installed are slid as a whole to the installation site, the lifting function of the SPMT is used in conjunction with the auxiliary supporting cylinders to lower the large engineering components to a certain height and install them in place by mutual force.

Description

Technical Field

[0001] The present invention relates to the technical field of large-part installation, and in particular to an engineering large-part installation process based on an SPMT trainset and an installation auxiliary structure thereof. Background Art

[0002] For some large engineering items, not only do they require specific vehicles and specific transportation methods during logistics transportation, but after being transported to the designated location, their installation also requires some specific tooling and other means to complete the installation. The difficulty of installation on some flat surfaces is much lower than that on a certain slope angle.

[0003] This is because the large engineering parts to be installed are too long, and there is a certain height difference between the slope and the horizontal road surface. It is difficult to quickly transfer the large engineering parts to be installed in a flat position to the slope for installation. The overall installation process is complicated, the installation period is long, and the installation efficiency is low. Summary of the Invention

[0004] The purpose of this section is to summarize some aspects of the embodiments of the present invention and briefly introduce some preferred embodiments. Some simplifications or omissions may be made in this section and the abstract and title of this application to avoid obscuring the purpose of this section, the abstract and the title of the invention, and such simplifications or omissions should not be used to limit the scope of the present invention.

[0007] Step 2: Load the supporting round tubes onto the SPMT motor vehicle and fix the large engineering component to be installed on it and lift it into place. Then, install multiple sets of auxiliary supporting round tubes on the bottom side of the large engineering component.

[0008] Step 3: The supported large engineering parts are moved horizontally to the side of the slope to prepare for the horizontal relay. The SPMT motor vehicle group reserved in the slope area also loads the supporting round pipes to start the sliding relay.

[0009] Step 4: The SPMT motor vehicles slide and relay each other under mutual force. When they slide into place, the auxiliary lowering steel columns and wedge plates are installed. At the same time, the supporting circular tubes are rigidly connected to the fulcrums of the large engineering parts to be installed with bolts. The lowering of the large engineering parts to be installed is completed by the mutual force between the supporting circular tubes and the auxiliary supporting circular tubes.

[0010] Step 5: After one section of the large project parts to be installed is installed, repeat the above steps to assemble multiple sections of the large project parts to be installed in sections.

[0015] S3: The SPMT motor vehicle group at the first support hole position is then withdrawn and transferred to the slope to wait for jacking force. After translating one support hole position, the first hole position group is re-used to jack up and force into place using the SPMT motor vehicle group in place;

[0016] S4: Then the SPMT motor vehicle group at the second support hole position is withdrawn and transferred to the slope to wait for jacking force. After being translated a distance of a support hole position, the second support hole position is jacked into place again;

[0017] S5: After the SPMT motor vehicle group at the 3rd hole position is withdrawn from the grouping, it is transferred to the 4th support hole position to complete the grouping, and then the SPMT motor vehicle group at the 2nd support hole position is transferred to the 3rd support hole position to be stressed. At this time, the 4th hole position vehicle group is transferred to the slope again to wait for stress, and the translation is continued according to the length of the large engineering piece to be installed, and the above alternating stress steps are repeated to complete the translation work of the large engineering piece to be installed.

[0035] Step 3: The supported large engineering parts are moved horizontally to the side of the slope to prepare for the horizontal relay, and the SPMT motor vehicle group reserved in the slope area is also loaded with the supporting circular tube 100 to start the sliding relay.

[0036] Specifically, the specific relay methods of the slip relay include:

[0037] S1: Divide the large engineering parts to be installed on the SPMT motor vehicle into multiple support holes, and record the support holes from 1 to N, where N is an integer greater than 5, and the size of N depends on the overall length of the large engineering parts.

[0038] S2: Integrate the remaining SPMT motor vehicle group into the second support hole and start lifting and loading until the monitoring pressure gauge is consistent with that of other vehicles;

[0039] S3: The SPMT motor vehicle group at the first support hole position is then withdrawn and transferred to the slope to wait for jacking force. After translating one support hole position, the first hole position vehicle group is re-used to jack up the already positioned SPMT motor vehicle group and is sealed and bound using chain 400.

[0040] S4: The SPMT motor vehicle group at the second support hole position is then withdrawn and transferred to the slope to wait for jacking force.

At the same time, the supporting circular tube 100 is rigidly connected to the fulcrum of the large engineering component to be installed with bolts. The lowering of the large engineering component to be installed is completed by the mutual force between the supporting circular tube 100 and the auxiliary supporting circular tube 200.

The above-mentioned supporting circular tubes 100 and auxiliary supporting circular tubes 200 are all multi-section detachable circular tubes. In addition, the large engineering parts to be installed are welded with a fulcrum reinforcement structure for stably supporting the supporting circular tubes 100 and the auxiliary supporting circular tubes 200.

[0048] In order to meet the customer's requirements for the overall installation of large engineering parts to be installed, the present invention utilizes the transverse mode of the SPMT motor vehicle group and adopts the mutual cooperation of multi-point support of the SPMT motor vehicle group to achieve the lateral relay of the large engineering parts to be installed between the road surface and the slope through mutual force. When the large engineering parts to be installed are slid as a whole to the installation site, the jacking function of the SPMT is utilized in conjunction with the auxiliary support cylinder to lower the large engineering parts to a certain height and install them in place through mutual force. During the entire process, the SPMT motor vehicle group cooperates with the auxiliary installation auxiliary structure to withstand the lateral force caused by the slope and prevents it from sliding downward after loading the large engineering parts to be installed, thereby improving the safety factor of the overall installation process.
