Problems solved by technology

At present, domestic methods for removing pile heads all use manual methods such as manual chiseling for crushing, which has the disadvantages of high labor intensity, low efficacy, and high cost.
In order to overcome the defects of the prior art, CN202000352 discloses a pile head breaker for concrete pouring piles, which has the defect that it is only suitable for pile heads with constant diameters, and cannot satisfy pile heads with different diameters.
In addition, the whole device needs to be hoisted by rings during the working process, which is difficult to operate

Embodiment Construction

[0020] The following is attached Figure 1-3 The present invention is further described in detail.

[0021] as attached figure 1 , 2 As shown in and 3, a pile head crushing device includes a lower positioning crushing mechanism, an upper crushing mechanism and a telescopic connector arranged between the lower positioning crushing mechanism and the upper crushing mechanism;

[0022] The lower positioning crushing mechanism is composed of two semicircular lower crushing assemblies butted together. The lower crushing assembly includes eight lower crushing units connected to each other. The lower crushing units include a lower mounting frame 11 fixedly arranged on the lower The lower hydraulic cylinder 12 on the mounting frame 11 and the lower crushing head 15 arranged at the top of the piston of the lower hydraulic cylinder 12; the two ends of the lower mounting frame 11 are provided with lower connection holes, and the two adjacent lower crushing units Connected by the lower ...

Abstract

The invention relates to a pile head crushing device which comprises a lower positioning crushing mechanism, an upper crushing mechanism and a telescopic adapting piece arranged between the lower positioning crushing mechanism and the upper crushing mechanism. According to the pile head crushing device, five oil ways are utilized, so that all groups of functional hydraulic oil cylinders are made to have coordination and consistency, and a pile head can be crushed accurately. The pile head crushing device has the advantages of being wide in application range, low in operation difficulty and convenient to use.

Description

technical field [0001] The invention relates to a pile head crushing device. Background technique [0002] At present, pile foundations are widely used as foundations in bridge construction, which have the characteristics of high bearing capacity and good seismic effect. The current piles are divided into prefabricated concrete piles and poured concrete piles. After the prefabricated piles are driven into the ground, a section of pile head will be left on the outside. , this section must be removed to expose the steel bars for welding with the upper ring beam. At present, domestic methods for removing pile heads all adopt manual methods such as manual chiseling to carry out crushing, which has the disadvantages of high labor intensity, low efficacy, and high cost. In order to overcome the defects of the prior art, CN202000352 discloses a pile head breaker for cast-in-place concrete piles, which has the defect that it is only suitable for pile heads with constant diameters,...
