Abstract

Usage: in the mining industry, mainly in the development of open pit deposits. SUMMARY OF THE INVENTION: a dump truck predominantly for a bulldozer loading comprises a chassis frame, a body mounted on it with laterally swiveling lateral sides and lateral turning cylinders. Each side board is formed by a frame, the lower side of which is charm-mounted on the platform of the body with the possibility of fixation in the desired position, and a shield placed on the inside of the frame. The upper side of the shield is pivotally mounted on the upper side of the last frame and is connected to it by hydraulic cylinders ensuring its rotation relative to the frame. The frames of the side boards are interconnected by hydraulic cylinders for turning the boards located at the end walls of the body and are made with stops on the outer sides to interact with the supporting surface in the open position of the side. 10 ill.

Description

The invention relates to the mining industry, namely, mobile tanks for rock mass, and can be used in open pit mining.

Known biaxial trailer containing a trolley with a drawbar and a frame bearing a tipper lifting and lowering body with a drive; in this case, the frame and the trolley are made with brackets carrying rotary two shoulders L-shaped levers, the long shoulders of which are connected to the axles of the trailer, and the short ones are with the rods of power cylinders mounted on the frame and the trolley.

This device does not unload transport vessels when creating their design with reduced clearance.

The closest in technical essence is a tipper vehicle - a hydraulic tipping device of dump trucks, which ensures the opening of the side wall due to the action of a system of hydraulic cylinders, rods and hinges installed under the underbody. This device is additional to the main one - a power cylinder, which provides lifting of one of the sides of the body in the transverse plane.

A disadvantage of this device is the impossibility of loading a transport vessel by raking a bulldozer at a level level.

The purpose of the invention is to facilitate bulldozer loading and improve working conditions,

This goal is achieved by the fact that in the known tipper vehicle, mainly for a bulldozer loading, comprising a chassis frame, a body mounted on it with side side swivel laterally transverse sides and hydraulic cylinders for turning the latter, each side side is formed by a frame, the lower side of which is pivotally mounted on the body platform with the possibility of fixing in the required position, and a shield placed on the inside of the frame, the upper side pivotally mounted on the upper side of the latter and connected ennym frame with cylinders, providing its rotation relative to the frame, wherein the frames are interconnected by said hydraulic cylinders turning boards which are arranged at the end sides of the body and the stop formed on the outer sides for engagement with the support surface in the open position side.

A dump truck for bulldozer loading includes a movement mechanism 1 and a body in the form of a platform 2 with sides. The end sides 3 of the platform are fixed, and the longitudinal sides 4 are hinged. Each hinged board consists of a support 5 and a ramp b, which are connected in two places: on one long side and by means of ram rams 7 to enable them to rotate relative to each other. The support is made in the form of a spatial structure having grooves 8 for pivoting with the ramp and the platform, as well as racks 9, stops 10 and protective walls 11. The support is pivotally connected to the platform via an axis 12, on the ends of which are fixedly fixed latches 13, which rotate synchronously with rotation of the supports. To the struts of the support on the side hinges 14 are attached power cylinders 7

0 rotation of the ramp, and the rods 15 of these cylinders to the eyes 16 on the inner side of the ramp. The supports in the upper part have eyes 17 to which telescopic power cylinders are attached

5 lift 18, placed in pairs in the transverse plane at the ends of the platform. To fix the hinged boards in the working and transport positions on the bed 19 of the movement mechanism

0 are installed at the bottom of the ends of the platform in the transverse plane of the double-acting hydraulic cylinder 20, the rods 21 of which interact with recesses 22 on the clips 13.

5 The device operates as follows.

After installing the transporting container at the loading place, the tractor engine (tractor) is

0 of the lift cylinders 18 opens one of the hinged sides 4 (towards the bulldozer) until the stops 10 of this side come into contact with the ground. In this case, the ramp 6 and the support 5 are in a folded state

5 (pos. 1 in Fig. 2), and the rods 21 of the double-acting hydraulic cylinders 20 are removed from the recesses 22 on the latches 13. After installing the flange 4 on the ground (pos. 2 in Fig. 2), the rods 21 are inserted into the recesses 22 on clamps 13,

0 A bulldozer heaps a rock typed in a dump onto platform 2, and a bulldozer can run into a ramp. After filling the platform as much as possible with a bulldozer, the latter

5 there is a sufficient amount of rock per ramp, from which the protective walls 11. protect the traction means with the help of lifting rams 18 lifts the side 4 when

0 withdrawn rods 21 from the recesses of the fix-. tori 13 to the transport position (pos. 3 in figure 2) and secures it by inserting the rods 21 in the recess 22 on the latches 13 of the axis 12. In case of mismatch

5 longitudinal axes of symmetry of the platform and the gravity of the load of the tractor means by lifting the ramp 6 with a power cylinder, its rotation 7 corrects equal. numbering capacity loading in the transverse plane. Next move

transporting containers with cargo to the place of unloading.

After the tank is installed at the unloading site, the tractor driver pulls the rods 21 out of the recesses 22 of the clamps 13 and, using telescopic lift cylinders 18, lowers the hinged board 4 until the stops 10 touch the ground, after which the board is fixed by the rods 21 in the order described above (pos. 4 in FIG. 2). Then the driver disengages the rods 21 of the bead 4 and, using the power cylinders 18 and the rotary servomotors 7, pushes the rock out of the tank (item 5 in FIG. 2). The rock remaining on the ramp 6 of the open bead 4 is discarded by turning the ramp behind by actuating the power cylinders 7 (pos. b in Fig. 2). In this position, the rock left on the ramp of the ejection board is poured between the racks 9 of the support 5 of the open side 4. After the container is unloaded, the driver folds the ramps of b with supports 5 with the help of cylinders 7 and brings the sides into transport position with the lifting cylinders 18 with fixing rods 21 axles 12 (1 in figure 2). After that, the tractor operator moves the transporting container to the loading point, after which the cycle is repeated.
