Problems solved by technology
[0002] At present, in civil construction sites, in order to carry out work such as wedge piles underground, a puncher is used to punch holes in the ground in advance, and then used after punching. There is a fixed connection between the hole shafts. In actual work, due to the different geology of the hole, it is very likely that the screw blade in the hole punching shaft will be stuck under pressure. Once stuck, It is very likely that the machine head will burn out, which has great limitations

The invention discloses a connection device with an overload protection function for a building perforating machine. The connection device includes a rotation shell, a connection plate structure, a first rotation shaft and a first connection plate, wherein the connection plate structure is fixed to the center of one end face of the rotation shell through bolts, the first rotation shaft is arrangedat the center of the end face of the connection plate structure, and the first connection plate is welded to the end of the first rotation shaft; a rotation column mounting area is arranged at the center of the rotation shell, a rotation column is mounted inside the rotation column mounting area, a plurality of semi-circular groove structures are formed in the side face of the rotation column, asecond rotation shaft is arranged at the top of the rotation column, wherein the second rotation shaft and the rotation column are integrally formed; the body of the second rotation shaft penetrates through the top of the rotation shell. The connection device with the overload protection function is used for connecting a head of the perforating machine with a perforating shaft for perforation, andnot only can delivery of normal rotation force be achieved, but also the overload protection effect can be achieved; during practical work, when the perforating shaft is in contact with the relatively hard ground, the connection device can rotate relatively, so that the perforating shaft and the head of the perforating machine are protected.
Description
technical field [0001] The invention relates to the technical field of construction machinery, in particular to a connection device with an overload protection function for a construction drilling machine. Background technique [0002] At present, in civil construction sites, in order to carry out work such as wedge piles underground, a puncher is used to punch holes in the ground in advance, and then used after punching. There is a fixed connection between the hole shafts. In actual work, due to the different geology of the hole, it is very likely that the screw blade in the hole punching shaft will be stuck under pressure. Once stuck, It is very likely that the machine head will burn out, which has great limitations. Contents of the invention [0003] The object of the present invention is to provide a connection device with overload protection function for a construction punching machine, so as to solve the problems raised in the above-mentioned background technology. ...
