Description

The utility model belongs to conveyor transport and can be used in mobile scraper loaders.

The known mobile scraper loader (SPSH-1), which is selected as the closest analogue, contains sections of the racking position: horizontal loading, horizontal unloading and inclined, as well as drive elements. At the same time, the sections of the lattice structure of the inclined and horizontal sections are placed in a frame assembled from side elements, made in the form of sheets with stiffening ribs, which rest on the GI soil.

In such a design of a mobile scraper loader, the installation of the sections of the grating of the inclined section is carried out together with the installation of the side elements of the frame, which are made in the form of sheets with stiffening ribs. For this purpose, the sections of the rake stand at the required angle of inclination are installed on special devices that allow to approximately withstand this angle of inclination. For example, such special devices can serve as vertical wooden supports. After the sections of the lattice structure are exposed, fastening bolts are installed in the slats of the sections, located on the sides, on which the side elements of the frame, made in the form of sheets with stiffening ribs, are put on through the holes. After that, the side elements of the frame are connected to the section of the lattice post and fixed at the base with transverse ties, as a result of which the side elements of the frame form an additional transport chute on the lattice post. After the installation of the sections of the rack and frame, the supports are removed.

During installation/dismantling operations of the inclined section of the racking post, the service personnel is forced to be placed inside the frame formed by the sections of the racking post and the debt elements of the frame, which creates for him additional risks of a traumatic situation. In addition, the process of combining the bolts installed in the slats of the rack section with the mounting holes of the side frame elements requires the use of lifting equipment, which is a labor-intensive operation.

Disadvantages of the given analogue include the risk of injury, as service personnel are forced to work inside the frame, in addition, the use of lifting equipment, supports, etc., increases the complexity of assembly/disassembly work.

З The creation of a new technical solution is based on the task of reducing the risk of injury for service personnel during the installation/disassembly of the inclined section of the grating post of the mobile scraper loader.

When performing the given task, a technical result can be obtained: providing the service personnel with a safe location outside the frame during installation/dismantling of the sloping section of the grating post and at the same time the ability to adjust the position of the grating post sections inside the frame.

Obtaining the declared technical result will provide consumer properties: improvement of the state of safety equipment during installation/disassembly works, as well as reduction of the labor intensity of their implementation.

In a mobile scraper loader, which contains at least one horizontal section and an inclined section, which is made in the form of a frame, inside which the sections of the grating position are fixed on the side elements, it is proposed, according to the useful model, to additionally introduce eccentric elements into the structure of the frame under the sections of the grating position, the axes of which fix the frames on the side elements from the outside, while installing the eccentric elements with the possibility of rotation and interaction with the rack section, as well as their assembly and disassembly through the holes additionally made in the side elements.

The features listed above, different from the prototype, are necessary and sufficient in all cases covered by the scope of legal protection of the utility model.

In addition, it is suggested: the eccentric element should be made in the form of an eccentric shaft; the axis of the eccentric element should be made with a shank.

The causal relationship between the newly introduced essential features of the useful model and the declared technical result is explained as follows. The introduction of eccentric elements into the structure of the frame under the rack sections, the axes of which are brought outside the frame to the on-board elements, allows during assembly/disassembly to adjust the position of the rack sections relative to the side elements of the frame with the help of eccentric elements for connecting the rack sections to the side elements with fasteners and at the same time, do not use wooden supports and lifting equipment. Designing the axis of the eccentric element with a shank allows service personnel to use the shank to control the position of the eccentric element on the outside of the frame, in a safer place. In this way, the declared technical result is achieved: providing the service personnel with a safe location outside the frame during installation/dismantling of the inclined section of the grating and at the same time the ability to adjust the position of the grating sections inside the frame, and consumer properties: improving the state of safety during assembly/ dismantling works, as well as reducing the complexity of their implementation.

The technical solution is explained by an example, the implementation of which is not the only possible one, but clearly demonstrates the possibility of achieving a technical result with the proposed new set of essential features.

The essence of the proposed technical solution is presented in the drawings, where: in fig. 1 shows the main sections of the mobile scraper loader; in fig. 2 shows part of the frame of the inclined section; in fig. C shows the position of the support element when the axes of the holes are shifted (4); in fig. 4 shows the position of the support element when the axes of the holes are aligned; in fig. 5 shows the fastening elements of the sections of the racking posture.

Brief description of the drawings: 1 - drive; 2 - tension head;

C - horizontal unloading area; 4 - inclined section; 5 - horizontal loading area; b - sections of the rib cage; 6.1 - shaped hole; 7 - frame; 7.1 - on-board elements; 7.2 - shaped hole; 7.3 - hole; 7.4 - spacer; 7.5 - hole;

Zo 8 - eccentric element; 8.1 - shank; 8.2 - fasteners; 8.3 - axis; 8.4 - bar; 9 - bolt; 10 - bar; 10.1 - finger.

The proposed technical solution is presented on the example of a mobile scraper loader, with a horizontal unloading section (3), an inclined section (4) and a horizontal loading section (5) placed between the drive (1) and the tension head (2) (Fig. 1).

In the example, an inclined section (4) is made in the form of a frame (7) (Figs. 1 and 2).

The technical result is achieved as follows.

In the on-board elements (7.1) of the frame (7) during their manufacture, the necessary number of holes (7.3) for eccentric elements (8) and shaped holes (7.2) are made, through which the service personnel during the installation/disassembly of the sections of the grating (b) can see the shaped holes (6.1) in the slats of the rack section (b), and also install the bolts (9), while being outside the frame (7) (fig. C, 4).

During the installation of the mobile scraper loader, the on-board elements (7.1), frame (7) and eccentric elements (8) are assembled. The eccentric element (8) with the axis (8.3) is installed through the holes (7.3) in the frame (7) and with the help of slats (8.4) is fixed to the side elements (7.1) with bolts. The axis (8.3) has grooves on both sides, in which the latches (8.2) are installed, which are fastened to the bar (8.4) with bolts.

Thus, an inclined section (4) is formed in the form of a frame (7), which is lowered from above and placed on the eccentric elements (8) of the section of the racking posture (6). If the inclined section consists of more than one section of the racking post (6), then the number of eccentric elements (8) is set according to the calculation - two for each section of the racking post (6).

Next, the sections of the rack post (b) on the side elements (7.1) of the frame (7) are fixed as follows. Before installing the bolts (9), connect the shaped holes (7.2) on the side elements (7.1) with the shaped holes (6.1) of the slats of the rack sections (6). To do this, the service personnel rotates the eccentric element (8) with a wrench for the shank (8.1) to a certain angle, which allows to move (raise) the section of the racking position (6) relative to the side elements (7.1) to the alignment of the shaped holes (7.2) by the amount A and (6.1) (Fig. 3, 4).

Then the bolt heads (9) are installed, which are fixed from displacement by a special bar (10) with a finger (10.1) (Fig. 5), which is placed in the hole (7.5) of the side element (7.1) and can accept the load from the weight of the racking section ( b) in case of removal of the compressive force from the eccentric element (8).

The eccentric element (8) can be made both stationary and removable. If the eccentric element (8) is made removable, after the rigid fixation of the section of the rack position (b) in the frame (7) of the inclined section (4), the eccentric element (8) can be dismantled through the hole (7.3) and used to install the next section of the rack position (6).

If necessary, spacers (7.4) can be installed to provide additional rigidity of the frame (7).
