Description

Technical Field

[0001] The utility model relates to a prefabricated comprehensive pipe gallery assembly test device, belonging to the technical field of underground pipe galleries. Background Art

[0002] At present, underground comprehensive pipeline corridors have great advantages in urban space utilization and resistance to natural disasters, especially in pipeline corridor crossing projects. Without destroying the original road structure and without affecting traffic, underground passages are formed, which have incomparable advantages over traditional wire pipes. More and more cities in China have begun to adopt prefabricated pipeline corridors as part of their planning, and the construction of comprehensive pipeline corridors has become a general trend in urban construction.

[0003] Most domestic subways and integrated power pipeline corridors use rectangular pipeline corridors. Pipe corridors are usually assembled by connecting multiple rectangular prefabricated pipe sections end to end. The main connection method of rectangular pipeline corridors is the socket type, with a socket on one side and a spigot on the other side. The prefabricated pipe sections that make up the pipeline corridor are usually divided into single compartments, double compartments or even multiple compartments. The horizontal assembly test of the pipeline corridor is a necessary procedure to inspect the shape and processing accuracy of prefabricated rectangular pipe sections. For each batch of pipe sections produced, rectangular pipe sections are randomly selected for assembly test. When conducting the horizontal assembly test of prefabricated rectangular pipe sections, the prefabricated rectangular pipe sections need to be assembled into continuous pipe sections with the end faces parallel to the ground. In order to measure the size and gap size of each part of the pipe section after assembly, several pipe sections should be erected on a base fixed on the ground, and the position should be adjusted by a crane to complete the assembly.

[0004] There are two problems in the current horizontal assembly test process of prefabricated rectangular pipe segments. The first is that the position of the pipe segment cannot be freely adjusted on the base, and there is no working space when multiple pipe segments are assembled. The second is that the prefabricated pipe segment is large in size and weight, and the position needs to be adjusted during the assembly test. The gantry crane is always in a hoisting working state, which has poor safety. When the pipe segment is hoisted, it is difficult to achieve its position and deflection angle corresponding to the pipe segments on both sides. In addition, when using a gantry crane to hoist heavy pipe segments, it is limited by the test site and is easy to cause bumps and damage to the pipe segment. It is difficult to confirm whether the docking is accurate before assembly, which brings inconvenience to the test. Utility Model Content

The rotating table 7 is a circular structure and is located on the surface of the support plate 5.

[0037] In the present technical solution, the translation mechanism includes a wheel seat 9 and a pulley 10. The wheel seat 9 is fixedly connected to the bottom of the support plate 5. The pulley 10 is rotatably connected inside the wheel seat 9. There are several wheel seats 9, and the several wheel seats 9 are evenly distributed on both sides of the support plate 5.

[0038] In this technical solution, two guide grooves 11 for the movement of the wheel seat 9 are opened on the surface of the top plate 4, and the top plate 4 located inside the guide groove 11 is provided with a guide strip 12, and the guide strip 12 is located inside the groove opened by the pulley 10.

[0039] In the present technical solution, an opening 13 for driving the motor 6 to move is opened in the middle of the top plate 4 , and the opening 13 is located between a plurality of wheel seats 9 .

[0040] In this technical solution, a hydraulic cylinder 15 is fixedly installed on the outer wall of the vehicle body 3 , and the hydraulic cylinder 15 is fixedly installed to the bottom of the top plate 4 , and the telescopic end of the hydraulic cylinder 15 passes through the side plate 14 and is fixedly connected to the support plate 5 .
