Description
Technical field
The utility model relates to the parts of using tractor in a kind of vehicle impact testing, and the extension that especially relates to a kind of tractor breaks off relations and keeps off handle mechanism.
Background technology
Vehicle impact testing is the most basic, the effective method of present comprehensive evaluation vehicle safety performance, and tractor is indispensable device in the vehicle impact testing, the extension that it comprises the vehicle body main body, is made up of retaining handle and camshaft clamp system assembly break off relations retaining handle mechanism, ratchet, guiding sheave, traction hook, clamp system assembly, the axle that breaks off relations, unhook axial trough, draw and link up with and the trailer wire rope.Extension unhook retaining handle in the existing tractor is single handle structure, in the impact test preparatory stage, hangs retaining handle one end that breaks off relations and cooperates with ratchet, and the other end cooperates with the camshaft top.The camshaft top is square, can only the retaining handle could be held out against on ratchet by spanner.Like this, can only earlier the retaining handle be held out against on ratchet, after ratchet holds out against the axle that breaks off relations, again the trailer wire rope be hung on the axle that breaks off relations.So, need the staff to crouch down operation during trailer, operating difficulties, operation intensity is big; The trailer time is longer, generally needs a few minutes to tens minute, and the special vehicle time is longer, inefficiency; If the fortuitous event of big displacement appears in instruction carriage, the staff is difficult for dodging because of crouching down operation, and is dangerous big.In addition, the retaining handle of existing tractor and the tolerance clearance of ratchet are bigger, if the damping of tractor is not good, the quick resilience of big displacement may take place after the tractor damping so, and the axle that breaks off relations this moment is deviate from from the traction hook not also, ratchet does not also rotate, there is a strong possibility rotates back between the ratchet again for retaining handle top ratchet end, get back to lockup state, cause Off-Dog Fault, produced misoperation.
Summary of the invention
The utility model solves the above-mentioned problems in the prior art exactly, provide a kind of tractor to hang unhook retaining handle mechanism, adopt the tractor of this mechanism, do not need the staff to crouch down operation, simple to operate, the trailer time is short, the efficient height, the axle that breaks off relations breaks off relations reliable, has guaranteed staff's personal safety.
For addressing the above problem, technical solution of the present utility model is: a kind of tractor is hung the retaining handle mechanism that breaks off relations, and it comprises retaining handle and camshaft clamp system assembly; The retaining handle is formed by clamping retaining handle and limiting block handle; Clamping retaining handle one end is circular arc, and the other end is a handle, and its circular arc end has square opening, and handle end has connecting hole; Limiting block handle one end is a top ratchet end, and the other end is retaining handle handle end, and the centre is the curved arc shape, and the centre has circular port, and retaining handle handle end has and clamp the corresponding connecting hole of connecting hole on the retaining handle, and the two is fixed together by web member; The camshaft lower end of camshaft clamp system assembly for the circular port of limiting block handle be complementary cylindrical, the square column of upper end for being complementary with the square opening that clamps the retaining handle, the camshaft upper end has spacing hole; Limiting block handle and clamping retaining handle are installed on the camshaft successively, and locating part is fixed in the spacing hole of camshaft.
Above-mentioned described web member is a coupling bolt.
Above-mentioned described locating part is a stop screw
The top ratchet end of above-mentioned described limiting block handle is than the thick 3-5mm of retaining handle handle end.After the top ratchet end thickening with the limiting block handle, even if the tractor resilience because the gap between limiting block handle and the ratchet has obtained reducing, the locking phenomenon can not take place, the misoperation odds reduces greatly, and the axle that guarantees to break off relations breaks off relations normal, tests more reliable.
Retaining handle of the present utility model adopts and clamps retaining handle and limiting block handle double-handle structure, can will clamp the retaining handle with spanner earlier is rotated in place, the unhook axle that will install the trailer wire rope again is installed in the unhook axial trough, rotate the limiting block handle again by hand, make it to hold out against on ratchet, make ratchet compress the axle that breaks off relations, the connecting hole that clamps retaining handle and limiting block handle is linked together with web member promptly to install.Since between limiting block handle and the camshaft for circular shaft is connected, rotate very easy, so, can connect the trailer wire rope earlier, stir the limiting block handle with hand again and hold out against ratchet, crouch down operation without the staff, do not need to prepare again the sponge backing plate yet, simple to operate, reduced staff's labour intensity, improved staff's personal safety, shortened the trailer time, improve the reliability that the axle that breaks off relations breaks off relations, improved work efficiency, guaranteed the compactedness of test.The trailer time shortened to about one minute, and not limited by vehicle.Whole apparatus structure is simple, cheap for manufacturing cost, simple operation, and is fit to the trailer system of all locked coil ropes, satisfies the impact test requirement.
