Embodiment Construction
[0020] Such as figure 1 , image 3 The existing pull arm locking device shown is composed of existing locking hook 5, existing large pull arm 1, existing single-stroke locking oil cylinder 8, tension spring 7, existing linkage frame 4 and existing linkage frame. The ear consists of 3 parts. Its self-unloading process, that is, the locking state of the existing locking hook 5 and the existing linkage frame lug 3: when the existing single-stroke locking oil cylinder 8 is unloaded, the tension spring 7 acts to tighten the rod 2, so that the locking hook 5 around the existing locking hook pin axis 6 directions image 3 The clockwise rotation of the angle of view is engaged with the existing linkage frame lug 3, so that the existing large pull arm 1 is rigidly joined with the existing linkage frame 4 as a whole, thereby rotating around the rotation axis of the linkage frame to realize the self-unloading function.
[0021] Its detachable process, that is, the existing locking hoo...

The solution of the present invention relates to a pull arm locking device, which consists of a lock hook (12), a large pull arm (9), a single-stroke locking oil cylinder (16), a return spring (14), a linkage frame (11) and a linkage frame Hanging ears (10) form. One end of the locking hook (12) is connected to the large pull arm (9), the middle part of the locking hook (12) is provided with a locking hook push rod (18), and one end of the return spring (14) is connected to the corner of the locking hook (12). connection, the other end of the return spring (14) is installed on the large pull arm (9) below the single-stroke locking cylinder (16); the front top plate of the single-stroke locking cylinder (16) is composed of a top cover, a buffer rubber pad and the top plate, and the buffer rubber pad is sandwiched between the top cover and the top plate. When working, the locking hook is controlled by the single-stroke locking cylinder to lock with the linkage frame; the locking hook is separated from the linkage frame by the return spring. The pulling arm locking device of the present invention works stably, and realizes the switching between self-unloading and detachable functions of the pulling-arm type garbage truck safely and reliably.
Description
technical field [0001] The invention relates to a draw arm type detachable garbage truck, in particular to a locking device for the cooperation of a large draw arm and a linkage frame. Background technique [0002] At present, the pull-arm type garbage truck can realize the combination and separation of the car box and the car. The existing pull-arm type detachable garbage truck realizes the self-unloading and unloading of the container through the joint and disconnection of the large pull arm and the linkage frame. The combination and disconnection process is realized by driving the locking hook through the single-stroke locking cylinder, and this model has been widely used at present. Among them, the arm locking device is the key device to realize the conversion between self-unloading and detachable functions. The quality of the arm locking device directly affects the efficiency and safety of the arm-type detachable garbage truck. The self-unloading process of the existin...
