Working tower of bored pile machine

Abstract

The invention provides a working tower frame of drilling a cast-in-place pile machine. The working tower frame comprises a supporting platform, a bracket, a truss, a weight box, a first winding engine, a second winding engine, a first steel rope, a second steel rope, a first lifting hook and a second lifting hook, wherein the supporting platform, the bracket and the truss are connected by a bearing and can be folded; a hanging ring is arranged at the side end of the supporting platform; a first guide pulley wheel, a second guide pulley wheel, a movable pulley wheel, a fixed pulley wheel and a directional pulley block are arranged at one end of the truss; the first winding engine and the second winding engine are fixed on the supporting platform; the weight box is connected with the other end of the truss; angle iron is welded at the upper and lower parts of the two sides of the truss respectively; reinforcing pipes are welded in angle iron grooves in the lower parts respectively. According to the working tower frame, the first lifting hook connected onto the movable pulley wheel is hooked on the hanging ring of the supporting platform so that the vibration problem of the truss when an impact drill bit is used for piling is relieved; the angle iron is welded on the two sides of the truss and the reinforcing pipes are welded in angle iron grooves, so that the lifting power of the truss is greatly enhanced.

Description

【Technical field】 [0001] The invention relates to the technical field of construction machinery, in particular to an operating tower of a bored pile machine. 【Background technique】 [0002] The tower is the working equipment of the pile driver. In the existing tower, when the percussion drill bit is used to drive the pile by the bored pile machine, the vibration of the truss will be caused, which will affect the piling effect, and the inner support rod of the truss of the tower is designed as a triangle, and its general lifting capacity is only from one ton to several Tons, the largest can lift more than ten tons, which cannot meet the needs of bored pile machines that require more than 20 tons at the inner end of the truss. [0003] Therefore, it is necessary to design a new working tower of bored pile machine. 【Content of invention】 [0004] In view of the various problems faced in the background technology, the object of the present invention is to provide an operatio...
