Abstract
The invention relates to a connecting rod type rear door locking mechanism for a garbage truck, which is applied to a carriage body and a rear door which are mutually hinged with the carriage of the garbage truck. The connecting rod type rear door locking mechanism comprises an oil cylinder, a rotating block, a connecting rod and a lock hook, wherein the rotating block and the lock hook are arranged on the side wall of the carriage through pin shafts respectively; one end of the rotating block is hinged with the oil cylinder; the end of a piston rod of the oil cylinder is hinged with the rear door; the other end of the rotating block is hinged with one end of the connecting rod; the other end of connecting rod is hinged with the lock hook; the tail end of the lock hook is provided with a clamping slot which is clamped with a lock pin; the lock pin is fixed on the rear door; and a limit pin is fixed on the carriage body of an area covered by the rotation of the rotating block for limiting the angle of the rotating block which counterclockwise rotates. Actual trials show that the improved rear door locking mechanism has 100 percent of closing success rate of the rear door and has high reliability. The improved carriage detachable garbage truck rear door locking mechanism has greatly improved reliability compared with that of the conventional locking mechanism and prevents the rear door from deforming at the same time.
Description
Technical field
The present invention relates to a kind of waste-skip link-type back door catch gear.
Background technology
The back door catch gear is the parts of an outbalance in the compartment removable garbage truck, and its radical function is to keep the back door to close in the vehicular transport way,, behind the garbage disposal plant back door in rubbish railway carriage or compartment is opened at vehicular transport, and rubbish is unloaded.Traditional back door catch gear reliability is relatively poor, easily causes the back door distortion, needs a kind of novel back door of design catch gear to substitute.
As shown in Figure 1, envelope is hinged by upset free bearing and back door on top, the back door is locked by latch hook in the bottom.Be arranged on the oil cylinder at middle part, the back door can be opened or closed.The upset free bearing is the elongated slot structure at vertical direction, and when closing at the back door, the upset bearing pin is positioned at the bottom of elongated slot.
As shown in Figure 2, the operation hydraulic efficiency pressure system is opened the back door, when the oil cylinder piston bar has just stretched out, promotes to move on the elongated slot of upset bearing pin in back door in the upset free bearing, and latch hook is left at the back door.The oil cylinder piston bar continues to stretch out, and the back door is rotated and is opened around the upset bearing pin, as shown in Figure 3.
Traditional back door locking mechanism structure is when opening the back door, and reliability is good, but when closing, the phenomenon at back door usually can take place to lock, as shown in Figure 4.Promptly when the back door closing movement will be finished, the back door moved down, and caused the lock pin on the back door should drop in the lock hook slot, but dropped on the outside of latch hook.Analyze reason, mainly be since the back door under self gravitation G effect, to bottom offset, and oil cylinder and back door are articulated structure, can not play the effect at support back door fully.Be depicted as force analysis as Fig. 4-2, F is the supporting power of oil cylinder to the back door, and the supporting power of upset free bearing is Rx and Ry.Be used for from actual the making of waste-skip, the success ratio of closing back door has only about 60% usually, and long-term use also causes the back door distortion.
Summary of the invention
The purpose of this invention is to provide a kind of waste-skip link-type back door catch gear, traditional back door catch gear reliability is relatively poor, easily causes the problem of back door distortion.
The objective of the invention is to be achieved through the following technical solutions:
Waste-skip link-type back door catch gear, be applied on the envelope and back door that garbage truck carriage is hinged, comprise oil cylinder, turning block, connecting rod and latch hook, described turning block and latch hook are installed on the sidewall in compartment by bearing pin respectively, one end and the described oil cylinder of described turning block are hinged, the piston rod end of oil cylinder is hinged on the described back door, one end of the other end of described turning block and described connecting rod is hinged, the other end and the latch hook of connecting rod are hinged, the end of described latch hook has a draw-in groove with the lock pin clamping, and described lock pin is fixed on the back door; For limiting the angle that turning block carries out left-hand revolution, on the envelope of turning block rotation institute overlay area, fix a locating dowel pin, described turning block is T-shaped.
Connect by a upset free bearing that is positioned at envelope top between described envelope and the back door, the fraising of upset free bearing is a circular hole.
When the operation hydraulic efficiency pressure system was opened the back door, the oil cylinder piston bar stretched out a bit of earlier, and this moment, turning block left-hand revolution certain angle up to contacting with locating dowel pin, moved on the drivening rod.Connecting rod drives angle of latch hook swing, and latch hook is promptly thrown off the lock pin on the back door.The oil cylinder piston bar continues to stretch out, and the back door is rotated and is opened around the upset bearing pin.
Improved type back door catch gear shows that through practical probation the success ratio of its closing back door is 100%, has good reliability.Improved carriage removable garbage truck back door catch gear, it is feasible not only analyzing its structure in theory, is used for from actual making, reliability improves greatly with traditional comparing also, has avoided the distortion at back door simultaneously, is comparatively ripe structure.
