Abstract

The invention relates to mining and transport equipment and is intended to be lifted from deep quarries of vehicles — heavy-duty dump trucks or dumpcars along steeply inclined routes. The purpose of the invention is to reduce the mass of the loading platform and to improve the operating conditions by ensuring that the horizontal position of the platform is constant when the slope of the track changes. A vehicle elevator on steeply inclined tracks contains inclined guides with cargo platforms moving along them and a drive. The loading platform 4 is made in the form of a plate to which the wheel wheels 5 and 6 are hingedly attached with the possibility of changing the angle in the vertical plane. The inclined guides 2 and 3 have additional guides forming two pairs of outer and inner rails. On the inner parallel rails, the counterweight 8 is placed with a possibility of movement, connected with the cargo platform by means of a rope 9 thrown over the pulley in the upper part of the elevator. The horizontal position of the loading platform is provided by increasing or decreasing the distance between the upper and lower guides, depending on increasing or decreasing the slope angle of the track. 5 il.

Description

Nata 9, thrown over the pulley at the top of the lift. The horizontal position of the loading platform is ensured by increasing or decreasing the distance between the upper and lower directions depending on the increase or decrease of the slope angle, 5 sludge,

The invention relates to mining vehicles and is intended to be lifted from deep quarries of vehicles — heavy duty dump trucks or dumpcars along steeply inclined routes.

The purpose of the invention is to reduce the weight of the loading platform and to improve the operating conditions by ensuring the horizontal position of the platform is constant with changes in the slope angle.

Fig, 1 schematically shows a lift, a general view; FIG. 2 is also a top view; Fig. 3 is a section A-A in Fig. 2 (the layout of the load carrying platforms on inclined guides with different tilt angles); FIG. 4 is a section BB in FIG. 2; FIG. 5 shows a pulley and a load bearing platform with a counterweight, kinematically connected by a rope.

The elevator includes a drive station 1 with two pairs of inclined guides, upper 2 and lower 3. On the guides of the accommodation, cargo platform 4, made in the form of a plate, to which articulated pairs of wheeled wheeled carts 5 and 6 are attached to one pair moving along the upper 2, and the other moving along the lower 3 guides, the distance h according to the norms between the guides at the angle of inclination of and the base distance 1 between the axles of the wheeled carriages is h l-sin d. conditions load Your platform is in a horizontal position at any angle of inclination and guides. The cargo platform (if it is technologically necessary) can be given any position. Dp of raising and lowering the cargo platform, haul rope 7 is connected with the driving station 1, Eq. loading of the load platform is carried out by counterweight 8

a rope 9 connecting them kinematically through the pulley 10,

The lift works as follows,

. In the initial position, the cargo carrying platform 4 is located at the berth of the lower horizon. The loaded dump truck 11 enters the platform and with it rises along the rails to the upper horizon. The path along which the platform rises may have a varying angle of inclination. By varying the distance between the upper and lower pairs of guides, the platform with the load is constantly in a horizontal position. The lifting and lowering of the cargo platform is carried out by the drive station, where ropes 9 are used as a traction body, which can be stocked into a three-time hawker. Counterweight 8 balances the weight of the loading platform 4. When lifting the platform, the counterweight is lowered, when the platform is lowered, the counterweight is raised along the rails 12 "Formula of the invention An elevator for vehicles on steep slopes containing a pair of guides, a loading platform mounted on these guides using undercarriages, and a driving platform is a station connected by a traction body with a platform that is different in that platform and improving operating conditions by ensuring the horizontal position of the platform when the slope of the track changes, the platform is made in the form of a slab, while the elevator is provided with an additional pair of guides arranged over the main guide and the horizontal position of the platform is provided by changing the relative position of main and additional guides depending on the angle of inclination of the track. . .
