Problems solved by technology

In the interval tunnels between subway stations and stations, each system needs a certain space to install corresponding system equipment, and the power supply line and evacuation platform load-bearing platform in the power supply system are mainly supported by brackets, so that the ring network cables and evacuation platform panels It can pass through the section in a neat and smooth straight line. The evacuation platform and the ring network cable support are usually distributed up and down, and are set on the left side of the driving direction, within a range of about 1 meter from the rail plane. The setting of the support system makes the cables and The overall placement of the platform within a plane range can not only effectively save the space in the interval, but also enable sufficient installation space for other professional wires and cables and equipment, and fully reflect the construction level. If the elevation of the support exceeds the design The requirements will directly affect the installation space of other professional equipment, and the load-bearing requirements of the evacuation platform after the height difference cannot meet the evacuation of personnel when the train fails, and the height difference of the cable support will affect the installation of the evacuation platform to a certain extent
[0003] During the construction process, the installation of the evacuation platform and ring network cable support will inevitably change due to human factors, environmental factors and other external factors, which are inconsistent with the design plan, resulting in changes in the bearing strength of the evacuation platform. The cable supports are not on the same horizontal plane, or the spacing between the supports is unequal, which may affect the emergency function of passengers in emergencies and the high failure rate of the power supply system. For example, during the construction process, the main link of the measurement deviates , the construction process is not strictly controlled, and the retest is not rigorous, etc. If these influencing factors cannot be overcome, it will cause rework.

Embodiment 1

[0037] The evacuation platform of this project requires that the actual installation height is 770mm on the rail surface. The ring network cable support and the evacuation platform share an anchor bolt, that is, the vertical distance between the upper surface of the pedal and the center point of the line connecting the two tracks. After the track alignment and slope adjustment is completed, Place the measuring equipment on a track without superelevation, then place the laser line thrower at the center of the platform where the measuring instrument is placed, adjust the height of the platform, and rotate the three support legs of the line thrower for leveling to ensure that the side blisters remain in the center Within the circle line, press the V / H button (V stands for vertical line, H stands for horizontal line) on the top of the laser line thrower to make it reach the elevation of the evacuation platform, first press OUTDOOR on the instrument, the light-emitting tube under the...

Embodiment 2

[0052] Before the measurement, the measuring equipment is placed near the starting point of the measurement, and the roller distance meter 6 is temporarily fixed on the side of the integrated measuring equipment to ensure that the roller distance meter 6 will not be displaced during the movement of the integrated measuring equipment. Ensure that the distance measuring wheel of the roller distance meter 6 can be in close contact with the ground, and then turn on the laser line thrower 5 to ensure that the vertical line of the laser line thrower 5 coincides with the first fixed point of the starting point of measurement. The person who determines a point fit measurement marks the location of the anchor on the side wall of the tunnel with a red marker.

[0053] The measurement of the distance between the evacuation platform support and the ring network cable support uses the roller distance meter to effectively solve the problems of low measurement efficiency and low measurement q...

Embodiment 3

[0063] After optimizing the integrated measurement equipment, the actual application measurement is carried out on site. In the process of advancement, 2 people are needed to complete the entire operating environment. After the measured data is retested using traditional methods, the measurement accuracy rate is as high as 100%. , After the preliminary measurement is completed, the on-site organization implements the construction work on the measured section according to the measurement data, and re-tests the finished product after construction using the integrated measurement equipment. The construction model section fully meets the requirements of the design and specification standards.

[0064] Using the boundary measurement technology of integrated measurement equipment, 10 points of the evacuation platform boundary with a boundary of about 200m have been selected for measurement and statistics, and compared with the traditional measurement method, the specific conditions ar...

Abstract

The invention relates to an integrated measurement device for a support for an evacuation platform and looped network cables. The device includes an equipment body of a frame structure. The frame structure includes an upper plane and a lower plane. Each of the upper plane and the lower plane is provided with a fixing platform used for fixing a laser demarcation device. The fixing platforms are indetachable connection with the upper plane and the lower plane. A side of the equipment body is connected with a distance limiting device. Fixed rods are perpendicularly arranged on the long edges ofthe upper plane. The fixed rods are connected with a fixed measurement ruler in a detached manner. A movable measurement ruler is arranged in the fixed measurement ruler. One end of the movable measurement ruler is provided with a wire suspending weight. The invention has advantages that measurement errors can be controlled effectively, rear-stage evacuation platform mounting quality is ensured and measurement efficiency is improved, and thus investment of labor cost is reduced.

Description

technical field [0001] The invention relates to engineering measuring equipment, in particular to an integrated measuring device for an evacuation platform and a ring network cable support. Background technique [0002] As a special mode of transportation, rail transit plays an important role in the urban public transportation system, and rail transit is composed of multiple systems such as civil structure, track, train, signal system, and power supply system. In the interval tunnels between subway stations and stations, each system needs a certain space to install corresponding system equipment, and the power supply line and evacuation platform load-bearing platform in the power supply system are mainly supported by brackets, so that the ring network cables and evacuation platform panels It can pass through the section in a neat and smooth straight line. The evacuation platform and the ring network cable support are usually distributed up and down, and are set on the left s...
