Description

Technical field

The device relates to the field of hoisting and transport engineering and can be used as part of a loading platform of a logging machine that transports assortments, in particular a forwarder. In addition, the device can be used in other areas where there is a need to transport long materials.

Prior Art

One of the common wood harvesting technologies is cut-to-length technology using a set of machines as part of a harvester and a forwarder [Shirnin Yu.A., Gaisin I.G., Ryganova S.G., Gataullin A.R. The results of monitoring the efficiency of the system of machines "harvester + forwarder" according to various technological schemes // Actual problems of the forestry complex. 2020. No. 57. URL: https://cyberleninka.ru/article/n/rezultaty-nablyudeniya-effektivnosti-raboty-sistemy-mashin-harvester-forvarder-po-razliclmym-tehnologicheskim-shem (date of access: 08/09/2021)]. The forwarder, by means of a manipulator, collects assortments at the clearing and transports them on a loading platform along cutting trails to the place of stacking. The cargo platform of the forwarder is a frame on which horses with racks are fixed [Klubnichkin E.E., Kotiev G.O., Fedotov M.V., Nakaznoy I.O., Rogachev D.I. Selection and justification of the design of the cargo compartment of a loading and transport vehicle // Scientific journal of KubSAU. 2020. No. 163. URL: https://cyberleninka.ru/article/n/vybor-i-obosnovanie-konstruktsii-gruzovogo-otseka-pogruzochno-transportnoy-mashiny (date of access: 08/09/2021)]. Racks limit the volume of the cargo platform. However, due to the fact that assortments can have different sizes, species, humidity, the weight of the transported pack varies greatly [Budnik P., Shegelman I., Baklagin V. Variability of forwarder truckload parameters in the Pryazha forestry division of the Republic of Karelia (Russia): a computer experiment // Central European Forestry Journal. 2020. No. 1(66). C. 12-22]. The carrying capacity of the machine can be exceeded before the loading platform is fully loaded [Shegelman I.R., Budnik P.V., Baklagin V.N. Methods of computer experiment in determining the carrying capacity and dimensions of the cargo compartment of a forest transport vehicle. Forest magazine. 2019. No. 6(372). S. 160-173].

Known rack loading platform forwarder, including a body made in the form of a hollow pipe with the possibility of its installation on the bunk loading platform [Ponsse forwarder under the designation WISENT, https://www.ponsse.eom/ru/produkciya/forvardery/produkt/-/ p/wisent#/].

The disadvantage of such a rack is that it does not allow the operator to determine the maximum loading level of the loading platform for a particular type of assortment.

Known rack loading platform forwarder, including a body movably connected to the conic of the loading platform, and the body is made of two articulated parts, while the rack is equipped with hydraulic actuators [Forwarder company Komatsu 875, https://www.komatsuforest.ru/machine/forwarders/ 875].

The disadvantage of the design is that it does not allow the operator to determine the maximum loading level of the loading platform for a particular type of assortment. In addition, the design of such a rack is relatively complex, which in practice reduces its reliability. The rack experiences not only static loads from loaded assortments, but also dynamic impacts from impacts by the manipulator or assortments held in the grip of the manipulator during loading and unloading of the loading platform.

Known rack loading platform forwarder, selected as the closest analogue, including a body made in the form of a hollow pipe with the possibility of its installation on the conic of the loading platform, and in the upper part with the ability to move along the longitudinal axis of the body telescopically installed support [Forwarder company John Deere 1210G, https://www.deere.ru/ru/forwarders/1210g-forwarders/].

The design of such a rack to some extent allows you to vary the size of the loading platform by raising or lowering the support. The telescopically mounted support is designed by the manufacturer to be used when transporting relatively short logs, typically 4 m. However, when transporting assortments with a length of 5 meters or more, the carrying capacity of the machine can be exceeded until the height of the racks begins to limit the loading level [Budnik P., Shegelman I., Baklagin V. Variability of forwarder truckload parameters in the Pryazha forestry division of the Republic of Karelia (Russia): a computer experiment // Central European Forestry Journal. 2020. No. 1(66). C. 12-22]. Thus, as in other analogues given, the design of the rack does not allow the operator to determine the maximum level of loading of the loading platform, which can lead to overloading the machine, and as a result, to its failure.

It should be noted that systems for measuring cargo on a forwarder platform are known from the prior art, usually supplied as an additional "option" (function) [Patent for invention RU2657024 "Method and device in the weighing system, the corresponding software product and a machine for loading and unloading materials" , announced on May 16, 2014, published on June 8, 2018]. For example, Ponsse forwarders can be equipped with the Ponsse loadoptimizer load weighing system /]. In general, such systems have software and mechanical parts. The latter is a manipulator suspension earring with integrated scales.

The disadvantage of load sensing systems is their complexity and the need for constant maintenance and calibration, as well as an increase in the overall cost of forestry equipment. Therefore, in practice, such technical solutions have not received wide distribution.

Thus, there is a task of creating a simple reliable technical solution that provides an indication of the limit level of loading the loading platform with logs, signaling the operator about a possible overload of the logging machine.

Disclosure of technical solution

The technical result consists in providing an indication on the rack of the loading platform of the maximum level of loading with assortments, which allows the operator to more fully and objectively evaluate the reserve by the carrying capacity of the timber transport machine when collecting and transporting assortments.

The technical result is achieved by the fact that the rack of the loading platform of the timber transport machine includes a body made with the possibility of connection with the loading platform, and the body is provided with an indicator element placed for movement in a recess made on the surface of the body, and the indicator element has a contrasting color to the color of the body. Description of drawings

The technical solution is illustrated in the drawings, where Fig. 1 - a variant of the implementation of the rack of the loading platform of a timber transport machine with one indicator element (isometry); fig. 2 shows the top of the loading platform post for the embodiment shown in FIG. one; fig. 3 is an indication element for the rack embodiment shown in FIG. 1 (isometry); fig. 4 - pad for fixing the indicating element on the housing for the embodiment of the rack shown in FIG. 1 (isometry).

Examples of implementation of a technical solution

The rack of the loading platform of the timber transport machine includes a body 1, made with the possibility of connection with the loading platform. In the preferred embodiment, the body 1 is made in the form of a hollow tube of circular cross section or other polygon (triangle, rectangle, hexagon, etc.). The fastening of the body 1 to the loading platform can be provided, for example, by bolting through a hole in the body (not shown in Fig. 1) or by welding.

In the preferred embodiment, in the upper part of the body 1 with the possibility of movement along its longitudinal axis, a support 2 is telescopically installed, which is a hollow pipe. Fixation of the support can be provided, for example, by means of a bolted connection (figures 1 and 2 show the place for the bolted connection, position 3).

The housing 1 is provided with an indicator element 4, which is movable in a recess 5 made on the surface of the housing 1, and the indicator element 4 has a contrasting color to the color of the housing 1. The indicator element 4 can be made of steel, plastic, wood, rubber, etc. materials.

In order to ensure the visibility of the loading level, the recess 5 is made on the side of the body 1, which faces the cabin of the forestry machine.

In one of the embodiments of the technical solution, fixing the indicating element 4, enabling it to move in the recess 5, is achieved by mounting the lining 6 on the body 1. The fixing of the lining 6 on the body 1 can be made by screw or other connection. It is advisable to make such a connection collapsible in order to be able to replace the indicator element 4. In addition, for the convenience of fixing the indicator element 4, it is advisable to make ears 7, 8 and a threaded hole 9 in its design (the thread is not shown in Fig. 3).

The possibility of moving the indicator element 4 is made in order to adjust the level of loading of the loading platform during the operation of the timber transport machine. Such an adjustment may be required when harvesting timber at different times of the year or different conditions for the location of the plot (swampy or dry terrain), which is due to changes in the moisture content of freshly cut wood, and, consequently, the weight of the assortment.

Housing 1 in some embodiments of the technical solution can be equipped with several display elements indicating the permissible level of loading of the loading platform of the timber machine for different assortments or logging conditions. For the same purpose, in some embodiments of the technical solution, the body 1 can be provided with several recesses 5, with indicator elements 4 placed in them.

The indicator element 4 has a contrasting color to the color of the body 1, which makes it visible to the operator of the forestry machine. For example, if the housing 1 is black, then the indicator element 4 is yellow or red or white. When making the body 1 with multiple display elements 4, their colors may be different.

The location of the indicator element 4 in the recess 5 is due to several reasons. This makes it possible to minimize the protrusion of the indicator element 4 above the surface of the body 1, which in turn protects it from mechanical impact during loading of assortments, and also prevents its displacement. It should also be noted that the placement of the indicator element 4 in the recess 5 when using the loading and unloading of the manipulator with a grip minimizes the likelihood of hooking on it of the protruding parts of the manipulator itself and assortments, which otherwise may lead to inconvenience in performing technological operations in which the manipulator is involved.

In the process of work, the operator of the timber transport machine, guided by the indication elements, can monitor the level of loading of the loading platform of the timber transport machine, preventing its overload.

Thus, the problem of creating a reliable technical solution is being solved, which provides an indication of the load level of the loading platform, signaling the operator about a possible overload of the logging machine.

The utility model is in no way limited to the embodiments described above. On the contrary, there are many possibilities for modification that will be obvious to the average person skilled in the art without departing from the basic idea of the utility model described in the claims.
