Description

The utility model relates to prom. transport and can find application in carrying out loading and unloading operations with the need to adjust the loading (unloading) location in height. In particular, when loading (unloading) ships in the port.

Known cradle conveyors with a complex route and the Donalt conveyor [1], which have an adjustment of the vertical position of the loading point. However, the cradle conveyors are poorly adapted for automated loading or unloading, because for this they need various devices. The loading and unloading of the Donalt conveyor in the hold of a vessel is usually done manually, which is a big disadvantage,

The purpose of the utility model is to create a construction of a reloading conveyor capable of self-unloading (self-loading) without the help of additional devices and with the possibility of adjusting the position of the loading (unloading) place of the conveyor in the vertical direction.

Figure 1 shows the proposed reloading conveyor, a General view of the first option in isometry; figure 2 - the main kinematic diagram for transporting cargo, isometry; figure 3 is a kinematic diagram of a mechanism for adjusting

position of the place of loading (unloading) in height (first option), right view; figure 4 is a diagram of a mechanism for adjusting the position of the place of loading (unloading) in height using a parallelogram mechanism (second option), isometry. In Figs. 3 and 4, the common carrier frame is shown conditionally by hatching.

A conveyor for piece cargo includes a common carrier frame 1, a movable frame 2, a movable frame 3, guide rollers 4, a basic kinematic diagram, load-bearing platforms 16, a mechanism for adjusting the vertical position of the movable frame 3, a drive of the main kinematic circuit 5, a drive mechanism adjust the position of the place of loading (unloading) in height 6, wheel 7 for the movement of the entire conveyor along the guides 8 and the drive rotation of the wheels 7 (not shown).

The basic kinematic scheme provides for the transportation of goods and consists of drive shafts 9 and 10, deflecting shafts 11, tension shaft 12, cantilever shafts 13, traction elements (for example, chains) 14 and 15. Two sprockets are installed on the drive, tension and deflecting shafts; on console - one at a time. Traction elements 14 and 15 round the sprockets, forming two traction contours. To the traction elements are attached load-bearing platforms 16, which have one-sided rigidity, i.e. have the ability to bend in one direction.

The drive shafts 8 and 9, six deflecting shafts 10, six cantilever shafts 12, guide rollers 4 are fixed on a common supporting frame 1, which is a mobile metal structure. The tension shaft 11 is fixed to the movable frame 3, the deflecting shaft 10 and two cantilever shafts 12. On the movable frame 2 there are four cantilever shafts 12.

The kinematic diagram of the mechanism for adjusting the position of the movable frame 3 can be performed in two versions.

In the first embodiment, it includes a shaft 17 with an asterisk and two bevel gears, two shafts 18 with two bevel and four cylindrical gears. In this embodiment, the movable frame 3 has two gear racks, and the frame 2 has four. Gear racks form kinematic pairs with cylindrical gears of shafts 17.

In the second embodiment, the mechanism is a parallelogram mechanism consisting of four connecting rods 19, four connecting rods 20, two traverses 21, a shaft 22 with two sections of multidirectional threads. The connecting rods 19 are pivotally fixed to the movable frame 2, and the connecting rods 20 to the movable frame 3. The traverses 21 at the ends have rollers 23. In this embodiment, the supporting frame 1 has four guides 24 (shown conditionally). An asterisk 25 is located on the shaft 22 of the parallelogram mechanism. The shaft 22 is fixed in the bearings of the common bearing frame 1.

The conveyor system operates as follows.

Load-bearing platforms 16 move along the highway by means of traction elements 14 and 15. When bypassing the turning points, the load-bearing platform is bent. When the cargo moves from the movable frame 3 further along the route, the traction elements are driven by drive sprockets rigidly sitting on the drive shaft 9, which, in turn, is rotationally driven from the drive 5. The direction of movement of the traction elements, and hence the load, can be changed for the possibility of carrying out the transportation operation in another m board (the cargo leaves the conveyor at the bottom of the frame 3), but for this it is advisable to install an additional drive (not shown) to the shaft 10 because in this case, the sprocket of the shaft 9 will be the largest tension drop.

If you need to adjust the place of loading or unloading (the lower part of the movable frame 3 in height in a strictly vertical direction in the first embodiment of the mechanism, the shaft 17 is rotated from the drive 6 and, thanks to the bevel gears, makes the shafts 18 rotate. Thanks to the rack and pinion gears formed by the racks on the movable the frames and gears of the shafts 18, the movable frames 2 and 3 move in opposite directions. If the frame 2 moves up, then the frame 3 moves down and vice versa.

closed circuits of traction elements change their configuration. Thus, the route along which the cargo moves changes its configuration, but the basic kinematic scheme that ensures the transportation of cargo remains able to function. The movable frames 2 and 3 move rolling on the guide rollers 4 or in the guides.

In the second embodiment, the shaft of the parallelogram mechanism 22 is driven into rotation from the drive 6 through a chain transmission with sprockets 25 and the movable frames 2 and 3 move in opposite directions due to the operation of the parallelogram mechanism. The traverses 21 of the parallelogram mechanism also move in opposite directions, and the rollers 23 at their ends move on the guides 24 of the supporting frame 1.

Other variants of the mechanism are possible.

The entire conveyor can move on wheels 7 along the guides 8 in the direction perpendicular to the direction of movement of the load on the platforms. For example, it may be necessary to perform loading operations along the entire length of the vessel served in the port.

There are many copyright designs and patents of various designs of load-bearing platforms with diagonal suspension on two chains. For example, [2]. Similar

platform and will be the load-bearing element in the proposed transfer conveyor.
