Description

The invention relates to municipal engineering, in particular, to devices for grasping and unloading containers into the back of a garbage truck.

The purpose of the invention is to increase the reliability of fixing containers in the clamping jaws.

FIG. 1 schematically shows a device for grabbing and unloading containers, side view; in fig. 2 is a view A of FIG. one; in fig. 3 shows a section BB in FIG. 2; in fig. 4 is a view of B in FIG. 2

The device is mounted on a garbage truck containing a base chassis 1 with a body 2, and has a top loading window. On the body, by means of the beam 3, the bearing boom 4 is pivotally fixed with the possibility of rotation in the vertical plane. The frame 7 is fixed with the possibility of rotation in the vertical plane by means of the hydraulic cylinder 6 with the main gripper on the cylindrical joint 5 on the free end of the carrying boom. The latter is made up of an inner clamping jaw 9 and an outer clamping jaw 10 mounted on the support element 8, which interact with opposite surfaces of one of the walls of the container 11. The inner clamping jaw consists of plates 12 and 13 interlocked with each other by means of a bracket 14 and suspended by sleeves 15 and 16 to the supporting element 8, made in the form of a thick-walled tube. Between the sleeves 15 and 16 is placed the sleeve 17, to which the outer clamping jaw is suspended, whereby when the container is fixed, this jaw is positioned between the plates 12 and 13 of the inner clamping sponge. A hydraulic cylinder 18 is mounted between the bracket 14 and the outer clamping sponge 10, the rod of which is connected with the outer clamping sponge by means of the hinge 19, and its body is connected by means of the hinge 20 to the bracket 14 of the plates 12 and 13 of the inner clamping sponge. The clamping jaws are provided with limiting their movement, made in the form of pins 21 and 22. secured to the carrier element 8 and placed in the grooves 23 of the sleeves 16 and 17. The circumferential distance between the pins corresponds to the angle of rotation of the clamping jaws relative to each other.

The frame 7 is provided with an additional gripper 24, made identical to the main gripper, and their bearing elements are located along the side walls of the container.

In order to grip containers with different linear dimensions, the carrier element of one of the grippers, for example, the main one, is fixed on the frame with the possibility of shifting in the horizontal plane through the holes 25 having keyways 26.

The side walls of the containers in the upper part are reinforced by catfish 27, which has the shape of an angle in the cross section.

The device works as follows.

The truck pulls up to the container 11 filled with my garbage container and the driver, turning the boom 4, lowers the main and additional grippers onto the container. The rods of hydraulic cylinders 18 vt chute in the housing and clamping jaws 9 and 10 are apart. At the same time, along with the 27 side walls of the container, it passes into the interior of the spaced jaws until the bearing elements 8 are touched. Then the hydraulic cylinders 18 are turned on, their rods are pulled out and the jaws turn together with the sleeves 15-17 around

axes bearing elements. The rotation continues until the clamping jaws compress the side walls of the container with the force determined by the parameters of the hydraulic cylinders 18. The holding of the container in the grips is ensured, on the one hand, by the friction forces between its walls and the surfaces of the clamping jaws, and On the other hand, due to the fact that along with the 27 container is located above the outer clamping sponge 10, preventing the container from falling out of the grippers. After that, the container with the garbage is lifted and tilted over the loading window of the body 2. After unloading, the container returns to its original position, freeing itself from the grips. To do this, turn on the hydraulic cylinders 18 on the return stroke of the rods. The bushings are rotated in the opposite direction. The clamping jaws are moved apart. The rotation of the latter occurs until the opposite ends of the grooves 23 are pressed into the pins 21 and 22, which limit them

turn. If it is necessary to change the distance between the carrier elements in case of transition to the lug of containers, and having larger linear dimensions between the side walls, the carrier element 8 of the main grip is rearranged to the next hole 25 in the frame 7.
