The utility model has designed; Preceding charger is set to include mutual group casing and overturning oil cylinder; Front end at portable beam is provided with mutual group casing, and it is hinged to help casing to be set to portable beam mutually, and an end of overturning oil cylinder is set to and mutual group casing is hinged and the other end is set to portable beam hinged.
The utility model has designed, and overturning oil cylinder is set to four and be set to be distributed in side by side on the mutual group casing.
The utility model has designed; Back charger is set to include carrier bar, pull bar, guide frame, positional cylinder, plugging pin oil cylinder, carrying oil cylinder and ear seat, is provided with pull bar at the two ends of carrier bar, and pull bar is set to the ear seat and is slidingly connected; Pull bar and ear seat are provided with jack; Plugging pin oil cylinder is arranged on the ear seat and expansion link is arranged in the jack of pull bar and ear seat, and the ear seat is set to be slidingly connected with the bottom girder of testing table, and it is hinged that an end of carrying oil cylinder is set to the bottom girder of and the other end and testing table hinged with the ear seat; Guide frame, ear seat and positional cylinder are set to three-link mechanism, and pull bar is set to connect with the guide frame contact.
The utility model has designed, and positional cylinder is set to two and be separately positioned on a side of pull bar.
The utility model has designed, and guide frame is set to the ear seat hinged, and an end of positional cylinder is set to the hinged and other end of guide frame and is set to the ear seat hinged
The utility model has designed, and also includes briquetting, and briquetting is set to polylith and is arranged on the downside of carrier bar, and briquetting is set to connect with the carrier bar universal joint.
Four, description of drawings
Fig. 1 is the synoptic diagram of the utility model:
Fig. 2 be Fig. 1 A to synoptic diagram.
Five, embodiment
Accompanying drawing is an embodiment of the utility model, specifies present embodiment in conjunction with accompanying drawing, include portable beam 1, mutually help casing 2, overturning oil cylinder 3, carrier bar 4, pull bar 5, guide frame 6, positional cylinder 7, plugging pin oil cylinder 11, carry oil cylinder 12, briquetting 18 and ear seat 19; Portable beam 1 is arranged in the stand of testing table and is set to connect with the stand slidingtype; Front end at portable beam 1 is provided with mutual group casing 2, and it is hinged to help casing 2 to be set to portable beam 1 mutually, and an end of overturning oil cylinder 3 is set to that the hinged and other end is set to portable beam 1 hinged with mutual group's casing 2; Be provided with carrier bar 4 in the rear end of portable beam 1; Be provided with pull bar 5 at the two ends of carrier bar 4, pull bar 5 is set to ear seat 19 and is slidingly connected, and pull bar 5 is provided with jack with ear seat 19; Plugging pin oil cylinder 11 is arranged on the ear seat 19 and expansion link is arranged in the jack of pull bar 5 and ear seat 19; Ear seat 19 is set to be slidingly connected with the bottom girder of testing table, and an end of carrying oil cylinder 12 is set to ear seat 19 the bottom girders hinged and other end and testing table hinged, and guide frame 6 is set to ear seat 19 hinged; One end of positional cylinder 7 is set to the hinged and other end of guide frame 6 and is set to ear seat 19 hinged; Pull bar 5 is set to connect with guide frame 6 contacts, and briquetting 18 is set to polylith and is arranged on the downside of carrier bar 4, and briquetting 18 is set to connect with carrier bar 4 universal joints; Positional cylinder 7 is set to two and be separately positioned on a side of pull bar 5, and briquetting 18 is set to three.
