Drawings
FIG. 1 is a schematic diagram of a prior art structure;
FIG. 2 is a cross-sectional view of the present utility model;
FIG. 3 is a schematic diagram of the structure of the present utility model;
in the figure: 101-flat pins, 102-locking pins, 201-cylinder body, 202-connecting ring, 203-piston, 204-drill rod, 205-pile head, 206-clamping plate, 207-steel wire cable, 208-bolt gasket nut assembly, 209-collar.
Detailed Description
The utility model is further explained below with reference to the drawings.
As shown in fig. 2 and 3, a lower cylinder body of a small hydraulic breaking hammer for a pavement pile driver comprises a cylinder body 201, wherein a piston 203 and a drill rod 204 are sequentially arranged in the cylinder body 201, a pile driving head 205 is arranged at the end part of the drill rod 204 extending out of one end of the cylinder body 201, and the pile driving head 205 is connected to the outer wall of the cylinder body 201 through a steel wire cable 207.
As a preferred solution, two clamping plates 206 are respectively disposed on two opposite outer walls of the cylinder body 201, and the two clamping plates 206 are fixedly connected by two sets of bolt gasket nut assemblies 208. Preferably, the bolt, washer and nut assembly 208 includes a bolt, washer and nut, with the bolt passing through one clamp plate 206, the other clamp plate 206 and washer in sequence, and then being tightened by the nut.
Preferably, each of the opposite ends of the pile driver head 205 is provided with a connecting ring 202. A collar 209 is provided on the outer wall of each clamping plate 206. The connection ring 202 and collar 209 correspond in position. The number of the steel wire ropes 207 is two, and each steel wire rope 207 sequentially passes through one connecting ring 202 and one lantern ring 209 positioned on the same side to lift the pile driving head 205.
The lower cylinder body of the utility model eliminates the flat pin, the lock pin, the flat pin hole and the lock pin hole in the prior art. The piston 203 reciprocates in the cylinder body 201, the piston 203 strikes the drill rod 204, and the front end of the drill rod 204 strikes the pile driver head 205, so that pile driving operation is realized. Because the drill rod 204 can slide when being vertically placed without the limit of the flat pin, the two sides of the pile head 205 are connected with the left clamping plate 206 and the right clamping plate 206 by the steel wire cables 207, thereby playing the roles of limiting and preventing the drill rod 204 from sliding.
