The shortcoming that the changing rig of prior art exists is: when the machine drawing frame, the handy manual mode of drag hook on the push-pull device at fixed is put down, in order to be suspended on the drag hook of frame, after frame is moved the position to, with manual mode the drag hook on the push-pull device at fixed is lifted again, realize breaking off relations with frame.
Summary of the invention
The purpose of this utility model is exactly the shortcoming that exists for prior art, the changing rig that provides a kind of side to go out the formula tandem rolling tube machine, and solving the push-pull device at fixed of existing changing rig can not automatic coupling and the problem of unhook.
The utility model is achieved through the following technical solutions:
A kind of side goes out the changing rig of formula tandem rolling tube machine, comprise: roll change buggy, the roll change buggy driving mechanism, machine frame push-and-pull device, track, described roll change buggy is by the transmission of roll change buggy driving mechanism, described roll change buggy is comprised of the vehicle frame of depositing old frame that is connected and the vehicle frame of depositing new frame, described machine frame push-and-pull device can be along described track at the vehicle frame of depositing old frame or to deposit the vehicle frame of new frame mobile, it is characterized in that: fixing vehicle frame with described machine frame push-and-pull device equal number is put the hook baffle plate on the described vehicle frame of depositing old frame, the hydraulic stem of described hydraulic cylinder is connected with the support of cutting somebody's hair, the support front end of cutting somebody's hair is installed and is cut somebody's hair, the support of cutting somebody's hair is hinged by rotating shaft and drag hook, fixing one at described drag hook lifts hook collision block and one and puts the hook collision block, they are staggeredly arranged along described shaft axis direction, put the hook baffle plate in described track installation with the track of machine frame push-and-pull device equal number, in frame the frame drag hook is set, described frame drag hook is provided with frame drag hook inclined-plane.
The head of described drag hook is provided with the inclined-plane corresponding with described frame drag hook inclined face.
The utility model compared with prior art, since the vehicle frame of depositing old frame fixedly vehicle frame put the hook baffle plate, hinged by the drag hook of rotating shaft and machine frame push-and-pull device with hydraulic cylinder, fixedly lift the hook collision block and put the hook collision block in rotating shaft, install in orbit and put the hook baffle plate, in frame the frame drag hook is set.Therefore, the utility model goes out the formula tandem rolling tube machine for side or opens when subtracting the machine roll change, can realize the function of push-pull device at fixed automatic coupling and unhook, has improved operating efficiency.

The utility model is further described by preferred embodiment below in conjunction with accompanying drawing.
The specific embodiment
Such as Fig. 1,2,3,4, shown in 5, a kind of side goes out the changing rig of formula tandem rolling tube machine, comprise: roll change buggy 1, roll change buggy driving mechanism 2, machine frame push-and-pull device 3, track 4, described roll change buggy 1 is by 2 transmissions of roll change buggy driving mechanism, described roll change buggy 1 is comprised of the vehicle frame of depositing old frame 5 that is connected and the vehicle frame 14 of depositing new frame, described machine frame push-and-pull device 3 can be mobile at the vehicle frame 5 of depositing old frame or the vehicle frame 14 of depositing new frame along described track 4, fixing vehicle frame with described machine frame push-and-pull device 3 equal numbers is put hook baffle plate 6 on the described vehicle frame 5 of depositing old frame, the hydraulic stem of described hydraulic cylinder 11 is connected with the support of cutting somebody's hair, the support front end of cutting somebody's hair is installed and is cut somebody's hair 15, the support of cutting somebody's hair is hinged by rotating shaft 16 and drag hook 7, fixing one at described drag hook 7 lifts hook collision block 8 and one and puts hook collision block 9, they are staggeredly arranged along described shaft axis direction, put hook baffle plate 10 in described track 4 installations with the track of machine frame push-and-pull device 3 equal numbers, in frame frame drag hook 12 is set, frame drag hook 12 is provided with frame drag hook inclined-plane 12-1.
The head of described drag hook 7 is provided with the inclined-plane 7-1 corresponding with described frame drag hook inclined-plane 12-1.
The utility model realizes that the principle of automatic coupling and unhook is as follows:
In the time of old frame will being pulled out from main engine bed, require the vehicle frame of depositing old frame 5 of roll change buggy 1 to be in working position, namely machine frame push-and-pull device 3 is mobile at the vehicle frame 5 of depositing old frame, before machine frame push-and-pull device 3 arrives main engine bed, the hook collision block 9 of putting on it is put at the vehicle frame of depositing old frame under the effect on hook baffle plate 6 inclined-planes and to be driven drag hook 7 and turn over certain angle, make the center of gravity of drag hook 7 around the left side (as shown in Figure 3) to its pivot center, drag hook 7 is set level under action of gravitation, when arriving main engine bed, drag hook 7 can advance while lifting along the frame drag hook inclined-plane 12-1 on the frame under the promotion of hydraulic cylinder 11, until cover frame drag hook inclined-plane 12-1, drag hook 7 is set level under action of gravitation again, so just realized the automatic coupling function, can drive drag hook 7 with hydraulic cylinder 11 old frame is pulled out from main engine bed this moment.After machine frame push-and-pull device 3 is moved old frame to position, the hook collision block 8 of lifting of drag hook 7 is put at track under the ramp effect of hook baffle plate 10 and is lifted, the center of gravity of drag hook 7 is around the right side (as shown in Figure 3) to its pivot center, drag hook 7 has so just been realized automatic unhooking function by on the inclined-plane that is placed on baffle plate 13 under action of gravitation.
In the time of new frame will being pushed main engine bed, require the vehicle frame of depositing new frame 14 of roll change buggy 1 to be in working position, namely machine frame push-and-pull device 3 is mobile at the vehicle frame 14 of depositing new frame, in this process owing to deposit on the vehicle frame 14 of new frame without putting hook baffle plate 6, so, can not affecting the 15 promotion frames of cutting somebody's hair of machine frame push-and-pull device 3 all the time by on the inclined-plane that is placed on baffle plate 13, the drag hook 7 of machine frame push-and-pull device 3 do not enter main engine bed.
The utility model also can be used as a changing rig that subtracts machine.
