Built-in integrated water connector reversing mechanism for single-power synchronous two-way mixing pile machine

Abstract

The invention discloses a built-in integrated water connector reversing mechanism for a single-power synchronous two-way mixing pile machine. The built-in integrated water connector reversing mechanism comprises a reversing mechanism body and a water connector. The water connector and the reversing mechanism body are integrally formed. The water connector is horizontally located in a transmission shaft of the reversing mechanism body. An expansion cavity is formed in an inner cavity in the top of the transmission shaft of the reversing mechanism body, the bottom end of a conveying shaft of the water connector is inserted below the bottom of the expansion cavity of the transmission shaft, and the outer wall of the upper portion of the portion, in the expansion cavity, of the conveying shaft is sleeved with a pair of bearings. Bearing seats located outside the bearings are fixed into the expansion cavity, the conveying shaft is fixed to the inner rings of the bearings through nuts, filler having the sealing effect is arranged at the bottom of the expansion cavity and located on the outer side of the conveying shaft, and a pressing flange is arranged at the top of the filler. The built-in integrated water connector reversing mechanism achieves the reversing function and the slurry conveying function, and is small in size, low in weight, novel in mechanism, simple, low in manufacturing cost and convenient to install; and an inner through hole is large, various curing materials of cement slurry, cement mortar, cement-soil slurry and concrete can be conveyed, and the range of the curing materials for mixing piles is expanded.

Description

technical field [0001] The invention relates to a stirring pile driver, in particular to a built-in integrated water joint direction-changing mechanism for a single-power, synchronous two-way stirring pile driver. Background technique [0002] In the construction of mixing piles in railway, highway, construction, municipal, water conservancy, and port projects, the pile forming method of the mixing pile machine usually adopts the single-direction rotating drilling and stirring of the drill bit, and the construction method of pile formation is very prone to occurrence of slurry and clogging during construction. drill phenomenon, and the efficiency is low, and the quality is not easy to guarantee. There are literatures that use double motors and double drill pipes for bidirectional drilling and mixing, although the drilling efficiency and pile quality are improved, but the pile driver needs to be modified or remanufactured, the installation is complicated, and the cost of pile...

Problems solved by technology

[0002] In the construction of mixing piles in railway, highway, construction, municipal, water conservancy, and port projects, the pile forming method of the mixing pile machine usually adopts the single-direction rotating drilling and stirring of the drill bit, and the construction method of pile formation is very prone to occurrence of slurry and clogging during construction. Drilling phenomenon, and low efficiency, quality is not easy to guarantee

There are literatures that use dual motors and double drill pipes for bidirectional drilling and mixing, although the drilling efficiency and pile quality are improved, but the pile driver needs to be modified or remanufactured, the installation is complicated, and the cost of pile driver modification and equipment usage is high

[0003] like figure 1 As shown, the water joint 12 of the existing CN200810052384.6 patent technology is usually installed on the upper or lower part of the steering mechanism 13, the structure is complex, the manufacturing cost is high; the size is large, and the installation is inconvenient. figure 1 Please refer to the embodiment of the present invention part for other symbols in , and the same components have the same symbols
