Summary of the invention
The purpose of this utility model provides 3 catch gears of a kind of compartment removable garbage truck, can make to grab, put that the rubbish railway carriage or compartment steadily moves to the fixed position safely in the process of railway carriage or compartment on the torque arm frame, make the locking of torque arm frame and rubbish railway carriage or compartment firmly, and locking mechanism structure is simple.
The purpose of this utility model is achieved in that torque arm frame rear end is hinged on the bearing pin of vehicle frame rear end, torque arm frame front end is upwardly extending upright arm, the upright arm trailing flank of torque arm frame has been bolted to connection cushion rubber, cushion rubber is positioned at upright arm bottom, rubbish railway carriage or compartment envelope leading flank is welded with the header board relative with cushion rubber, and upright arm cooperates rubbish railway carriage or compartment envelope fore-and-aft direction spacing by cushion rubber with header board; The a pair of symmetrical guide plate of welding on the longeron of vehicle frame underframe, guide plate is positioned at the longeron middle part of underframe, rubbish railway carriage or compartment downside left-right symmetric is welded with guide rail, spacing is wider than spacing between left guide plate and the right guide plate between left rail and the right guide rail, and guide rail cooperates formation spacing to rubbish railway carriage or compartment left and right directions with guide plate; A pair of latch hook is welded in dumping of torque arm frame rear portion symmetrically on the frame, a pair of lock frame of welding on the base plate of rubbish railway carriage or compartment, and it is spacing that latch hook insertion lock frame hooks the formation above-below direction with the rubbish railway carriage or compartment.
Described latch hook has the hook portion that extends back and stretch out.
Described lock frame comprises the open lower side link span that is welded on the envelope bottom, and the link span open lower side is provided with cross bar, and the gap of lock frame is inserted in the cross bar top for latch hook.
Described guide plate upper outside is the inclined-plane.
Owing to adopt technique scheme, cushion rubber is to the spacing cooperation composition of header board front end locking point, it can limit the rubbish railway carriage or compartment with respect to the motion forward of torque arm frame, because cushion rubber employing hardness is 65 ± 5 ° rubber, alleviates the impact effect of rubbish railway carriage or compartment to the torque arm frame simultaneously.Cushion rubber is positioned at upright arm bottom, more can bear the impact in rubbish railway carriage or compartment, slows down the slip forward of rubbish railway carriage or compartment, avoids the rubbish railway carriage or compartment to impact the excessive damage that causes upright arm.Guide plate and guide rail are formed the middle part locking point, and spacing is wider than spacing between left guide plate and the right guide plate between left rail and the right guide rail, and guide rail is limited in the guide plate both sides, can with the rubbish railway carriage or compartment with respect to the play distance limit of torque arm frame left and right directions within 8mm.Latch hook is formed the rear portion locking point with the lock frame, and the hook portion upper surface that latch hook inserts the lock frame and the upper surface of lock frame through hole be at a distance of 3mm, and the distance limit that latch hook moves up and down the rubbish railway carriage or compartment with respect to the torque arm frame is in 3mm.Latch hook is arranged on dumping on the frame crossbeam of torque arm frame rear portion, and is more firm to the locking of rubbish railway carriage or compartment.
Described guide plate outer upper is the inclined-plane, and the inclined-plane has guiding and positioning effect, and when the rubbish railway carriage or compartment tilted, guide rail was on the guide plate inclined-plane, and guide rail is slowly landing downwards along the inclined-plane, finally reaches the right and left balance.The inclined-plane has buffering effect, makes the placement in rubbish railway carriage or compartment more steady.
