PURPOSE: A smart hock connection device for transport of concrete pipes is provided to improve the safety of piping by stably connecting concrete pipes. CONSTITUTION: A smart hock connection device for transport of concrete pipes comprises an upper plate(11), a hydraulic cylinder(16), and a hydraulic driver(18). The upper plate comprises a connection part(12) including a through hole(13) in which a hook(40) of a wire(41) is inserted and a support piece(19) with a bolt hole. The hydraulic cylinder raises and lowers a lower plate in the vertical direction. The hydraulic driver operates the hydraulic cylinder by being connected to hydraulic hoses of the hydraulic cylinder and a hydraulic pump. One ends of first and second connecting members(22a,22b) are connected to the either side of the support piece, and the other ends to a fixing piece(21) of a hock(20) composed of a first and a second tong part(20a,20b). |
