Jam release device, system, model and design method for coiled tube drilling rigs

A jam release device model for coiled tube drilling rigs, comprising:

• a drive shaft assembly, wherein an end portion of the drive shaft assembly is fixed to a motor rotating shaft of a drive motor assembly, the drive motor assembly is fixedly connected to a base frame assembly so as to drive the drive shaft assembly to rotate around a connection point thereof with the drive motor assembly;
• a first lever assembly, wherein the first lever assembly is rationally connected to the base frame assembly via a first fulcrum, the first lever assembly is further provided with a first groove, on the drive shaft assembly is further fixedly provided an input end portion, and the input end portion is slidably connected to the first groove on the first lever assembly so as to drive the first lever assembly to rotate around the first fulcrum;
• a second lever assembly, wherein the second lever assembly is rotationally connected to the base frame assembly via a second fulcrum, the second lever assembly is further provided with a second groove and an output groove, on the first lever assembly is fixedly provided a transmission end, and the transmission end is slidably connected to the second groove on the second lever assembly, so as to drive the second lever assembly to rotate around the second fulcrum;
• and
• on the output groove is slidably arranged an output end portion, and the output end portion is used to connect with a chain roller base system model of a drilling rig, so that the chain roller system model applies high-frequency axial vibration excitation to a coiled tube clamped.
