Description

High-efficient quick detachable spiral pipe jacking machine guide bar frock

Technical Field

The utility model relates to a municipal administration construction equipment technical field specifically is a quick detachable spiral push bench guide bar frock of high efficiency.

Background

With the continuous improvement of the urbanization level of China, the discharge capacity of the rain and sewage drainage pipeline in the original urban area is tested, and some cities have the phenomenon of 'seeing the sea' in rainy season, so the rain and sewage drainage pipeline as one of urban hardware must be rebuilt or modified. The spiral pipe jacking machine is special construction equipment suitable for urban low traffic influence, and overcomes the defects that the construction period is long, the damage to roads is serious, a large amount of repeated construction is generated and the like in the traditional construction mode of excavating and laying pipes. The whole process of completing finished pipe jacking construction of the spiral pipe jacking machine is realized by three jacking steps, namely jacking guide rod tooling, jacking spiral dumping system tooling and jacking finished pipes. The first two steps are realized by special tools, wherein the jacking guide rod tool is the first step of pipe jacking construction and determines the precision deviation control of the pipe jacking construction and the precondition whether the subsequent construction can be carried out. In order to facilitate processing, manufacturing, transportation management, adaptation to the requirements of narrow space operation in a well and the like, a guide rod tool is usually manufactured into a plurality of sections of individuals with equal length, and two ends of each section are connected in a male-female octahedral socket hole mode. The octahedron can transmit the torque of the main equipment in the circumferential direction to enable the guide rod to rotate; the octahedron is axially fixed by bolts, and the guide rods can be connected into a whole.

As shown in fig. 6, the two ends of the guide rod are socket hole structures for connection, wherein one end of the socket hole structure is an octahedral shaft-shaped structure, and the other end of the socket hole structure is an octahedral hole-shaped structure. Smooth surface through holes are respectively processed at proper positions on two parallel bearing surfaces in octahedrons on two sides of the shaft hole along the same straight line direction of the length of the guide rod. After the two guide rod shaft hole ends are assembled, aligned and assembled, octahedral structures of the two guide rod shaft hole ends are matched with each other, four unthreaded holes at the shaft hole ends form a straight line along the circumferential direction of the guide rods to form a passage connected by a bolt, the bolt can penetrate through the passage during construction, the tail end of the bolt is locked by a nut, and the two guide rod tools are connected.

If the barrier is touched in the jacking process, the jacking rod tool can be pulled back in time, and the waste of manpower and material resources taken out from the excavation ground is avoided. However, the bolt connection method takes a long time for installation and tightening, and is inconvenient to disassemble. The construction efficiency is seriously influenced, the time consumed for connecting the guide rods is 2-3 times of the time consumed for jacking, and therefore the connection mode needs to be optimized and improved to improve the construction efficiency of equipment.

Based on this, the utility model designs a high-efficient quick detachable spiral top of tube machine guide bar frock to solve the above-mentioned problem of mentioning.
