Description

The present invention relates to the field of hoisting and transport engineering, namely to devices based on overhead rope systems for the operational mobile deployment of transport and handling cargo and passenger ropeways in unequipped and hard-to-reach areas, if necessary, create temporary or seasonal crossing facilities, eliminate natural or man-made emergencies.

A self-propelled end station is known (patent RU No. 200827, V61V 7/06, 2020) [1] in the form of a mobile chassis equipped with outriggers and anchors, intended for use with another similar chassis as part of a mobile cable car, containing drive and tension mechanisms, an end support fixed on the overframe structure of the supporting frame with a rope pulley located on it and an envelope rope pulley; the ability to move in a vertical plane with the help of a lifting hydraulic cylinder.

The disadvantages of this design are that the vertical and horizontal support reactions in the attachment point of the end support, which, during the operation of a mobile cable car, perceives very significant loads from the tension of the load-bearing rope by the weight of the transported load and the force of the tension mechanism, are completely perceived when transferred to the ground support base. an additional transmission link, which is the carrier frame of the self-propelled chassis. On the one hand, this leads to the formation in the metal structure of the supporting frame of a significant level of stress-strain state, variable in time due to dynamic loads on the supporting-traction rope from wind action and elastic vertical vibrations of the rope under the action of inertial loads from the transported cargo. This contributes to the accelerated development of dangerous fatigue cracks both in the metal itself and in the welds of the overframe structure and the supporting frame, and also increases the risk of brittle cracks of cold brittleness during operation in conditions of negative ambient temperatures, which negatively affects the reliability of the mobile road as a whole. (for example, on the coefficients of readiness, use, operational readiness, etc.) and complicates the activities for its maintenance and repair. On the other hand, this negatively affects the overall stability of the self-propelled end station in the conditions of its possible overturning [2], which is significantly reduced due to the high-altitude location of the attachment point of the end support on the supporting frame, i.e. at a certain height (~1.5 m) relative to the supporting surface - the ground.

There is a known type of mobile navigable cable car suitable for difficult terrain (patent CN 108791318 A, B61B 7/00, B61B 7/06, 2018) [3], containing two end self-propelled transport units on a caterpillar chassis, connected by a common carrier-traction rope , along which the cargo trolley with the transported cargo moves, and additional intermediate supports for maintaining the rope in the span between the end transport installations are not provided.

The technical disadvantages of this design are fully similar to the disadvantages of the analog discussed above [1].

The closest in its technical essence to the proposed invention, adopted as its prototype, is an overhead cable car (patent RU No. hydraulic outriggers of the main self-propelled transport installation, and is also equipped with an additional self-propelled transport installation, anchored by a tensioning device along the axis of the cable car and located towards the main self-propelled transport installation so that the longitudinal axes of the installations are located along the longitudinal axis of the cable car, as well as a closed tensioned carrier-traction rope with trailers, bending around pulleys and relying on traction units, located on telescopic supports located along the axis of the cable car.

The considered prototype has a number of significant design and functional disadvantages: 1) Drive rope pulleys located on self-propelled transport installations are mounted permanently in a horizontal plane, which requires, with a difference in heights, location on the ground at the end points of the cable car route of self-propelled transport installations, the use of intermediate telescopic supports not only to support the carrier-traction rope along the length of the route, but also to connect the end sections of the cable car with a horizontal orientation of the specified cable with an inclined section of the cable car. The presence of such end sections with a strictly horizontal orientation of the carrier-traction rope is a prerequisite for the high-quality operation of the considered mobile cable car, since according to known experimental data (for example, [5]), even slight deviations of the longitudinal axis of the load-carrying rope from the plane of the rope pulley lead to increased wear profiled pulley stream and the rope itself. According to [5], the deviation of the pulley groove axis from the rope axis should not exceed 1 degree in order to avoid intensive wear of both the profiled pulley groove and the carrying-traction rope itself. Intensive wear leads to a decrease in the service life of the elements of the cable system of a mobile cable car and the safety of its operation. 2) The presence of traction units, which must be sufficiently accurately installed both along the longitudinal axial line of the cable car route, and by telescoping the intermediate supports installed on them - in the longitudinal vertical plane of the cable car route, takes considerable time and requires a significant amount of installation work and installation personnel, which significantly increases the duration of installation / dismantling and reduces the speed of deployment of the mobile cable car. 3) The presence of intermediate traction installations also excludes the use of the cable car of the considered design in the case of difficult terrain between the main self-propelled transport installations (ravines, gorges, rivers, swamps, etc.) or the presence of temporary obstacles (destruction of buildings and structures, blockages, cracks during earthquakes, etc.).

An analysis of the analogs and the prototype of the proposed invention shows that, along with the individual specific disadvantages noted above, all the considered analogs and the prototype have a common functional drawback: the need to deliver at least two self-propelled transport installations of significant dead weight used in as terminal stations of a mobile cable car, and possibly several additional traction units (on self-propelled chassis or on towed trailers) requires the construction of the necessary roads or column tracks at least in the minimum volume. This requires time and money to carry out the specified engineering work and excludes the use of cable cars of the considered design in hard-to-reach areas (for example, in the coastal zones of the Arctic and Primorye, taiga regions of Siberia, etc.).

The technical problems to be solved by the present invention are:

1) a significant reduction in financial and material costs, a reduction in the number of operating personnel and an increase in the efficiency of deployment (assembly and dismantling) of a mobile cable car, a significant reduction in operating and maintenance costs of a mobile cable car during its operation;

2) increasing the reliability of the operation of a mobile cable car, in particular, increasing such basic quantitative characteristics as availability, utilization, operational readiness, etc.;

3) expanding the possibility of using a mobile cable car in hard-to-reach and (or) in advance non-equipped areas with difficult natural terrain, access to which using known modes of transport, except for air, is impossible or very problematic due to unacceptable costs of money or time (for example, in coastal zones of the Arctic and Primorye, taiga regions of Siberia, etc.).

To solve these technical problems in a fast-mounted mobile cable car in the form of two fast-mounted end stations, each of which has an end support fixed on a bearing base with a rope pulley located on it, drive and tension mechanisms to maintain the necessary tension and ensure the movement of flexible ropes, as well as a mechanism for transferring the end support from the transport position to the working position and a mechanism for holding the end support in the working position, moreover, these end stations are connected by a single cable system, including moving closed tensioned bearing and traction or carrier-traction flexible ropes with devices attached to them for suspension and holding of freight or passenger rolling stock for transportation of various goods or passengers, the bearing base is made of six bearing plates pivotally connected to each other, which are folded in the transport position, thus forming a the walls of a closed rectangular container at once, and in the working position they are laid out, forming a flat horizontal platform, and the necessary technological equipment, including, among other things, an end support of variable height, a mechanism for transferring the end support from the transport position to the working position, a mechanism for holding the end support in the working position, devices for fastening the supporting base on the ground and a cargo crane-manipulator, permanently fixed on the bearing plates and does not provide for additional rearrangement when deploying a mobile cable car.

The invention is explained in more detail with the help of the drawings. All elements not required for a direct understanding of the invention are excluded.

The essence of the invention is as follows.

The bearing base of the terminal station of a fast-moving mobile cable car consists of six bearing plates: front end 1 (Fig. 1-9), rear end 2 (Fig. 1-9), right side 3 (Fig. 1-9), left side 4 (Fig. 2, 4, 5, 9), lower 5 (Fig. 1-9) and upper 6 (Fig. 2, 3, 6-8). In the working position of the end station, all the carrier plates are deployed into a flat horizontal platform (Fig. 1, 2), and in the transport position of the end station, they are folded, thus forming the walls of a closed rectangular container (Fig. 3-5). Bearing plates are, for example, welded lattice structures formed by transverse 7 (Fig. 1, 4) and longitudinal 8 (Fig. 1, 4) metal rods of a box-shaped or open profile and covered on both sides with sheet metal decking. The sides of the bearing plates are connected in pairs with each other by cylindrical swivel joints, namely: the front end 1 (Fig. 1-9) - from the bottom 5 (Fig. 1-9), the lower 5 (Fig. 1-9) - from the rear end 2 (Fig. 1-9), rear end 2 (Fig. 1-9) - from the top 6 (Fig. 2, 3, 6-8), upper - from the right side 3 (Fig. 1-9) and left side 4 (Fig. 2, 4, 5, 9). These swivel joints are quick-release and are formed by pairs of lugs 9 (Fig. 1-5, 8), fixed on the upper surface of the connected bearing plates (for example, by welding), into the coaxial holes of which the hinge pin 10 is inserted (Fig. 1-5) and is fixed from axial movement, for example, with a nut (conditionally not shown). On the side surfaces of the front 1 (Fig. 1-9) and rear 2 (Fig. 1-9) end and bottom 5 (Fig. 1-9) bearing plates are fixed (for example, by welding) U-shaped eyes 11 ( Fig. 1-9). On the side surfaces of the right 3 (Fig. 1-9) and left 4 (Fig. 2, 4, 5, 9) side bearing plates are fixedly fixed (for example, by welding) flat eyes 12 (Fig. 1-9). In the transport position, flat eyes 12 (Fig. 1-9) enter the grooves of the U-shaped eyes 11 (Fig. 1-9), and hinge pins 13 (Fig. 1-9) are inserted into their coaxial holes and are fixed from axial movement , for example, by means of a nut (not shown conventionally), which creates a quick-release swivel of the respective carrier plates. On the upper surfaces of the lower 5 (Fig. 1-9) and upper 6 (Fig. 2, 3, 6-8) bearing plates are installed (for example, by welding or threaded connection) rigging fasteners 14 (Fig. 1-5, 7-9) (for example, eye bolts) for attaching an end station located in a transport (non-deployed) position on a vehicle (for example, on a railway or automobile platform, deck or hold of a watercraft, external sling or in the cargo compartment of an aircraft ). On the upper surfaces of the bearing plates, all mechanisms, devices and assemblies that are part of the main technological equipment necessary for the operation of the fast-mounted mobile cable car, as well as auxiliary devices necessary in the process of deploying or dismantling the mobile cable car, are permanently fixed. On the lower bearing plate 5 (Fig. 1-9) fixed end support 15 (Fig. 1, 2, 4, 5, 8, 9) variable height, for example, by telescoping one or more sections 16 (Fig. 1, 4, 5, 8, 9). The end support is a supporting metal structure for installing a rope pulley 17 (Fig. 1, 2, 4, 5, 8, 9) with a protective casing 18 (Fig. 1, 2, 4, 8, 9) and the drive mechanism 19 ensuring its rotation ( Fig. 1, 4, 8, 9). End support 15 (Fig. 1, 2, 4, 5, 8, 9) using a cylindrical swivel formed in pairs of conjugated lugs 20 (Fig. 1, 8) and 21 (Fig. 1, 4, 8, 9) and inserted into their coaxial holes of the hinge pin 22 (Fig. 1, 4, 8, 9), has the ability to rotate in a vertical plane to install the end support in the required working position, taking into account the natural sagging of the carrier-traction rope 23 (Fig. 1, 2) under its own weight and the weight of the transported cargo [6]. The specified rotation in the vertical plane is performed by the mechanism for transferring the end support from the transport position to the working position. The nodes of the mechanism, including the lifting hydraulic cylinder 24 (Fig. 1, 2, 4, 7-9), are permanently fixed on the upper surface of the lower carrier plate 5 (Fig. 1-9). The body of the lifting hydraulic cylinder 24 (Fig. 1, 2, 4, 7-9) is fixed on the upper surface of the lower bearing plate 5 (Fig. 1-9) using a cylindrical hinge formed by pairs of installed lugs 25 (Fig. 1, 2, 7-9), in the coaxial holes of which the hinge pin 26 is inserted (Fig. 2). The rod 27 (Fig. 4, 7-9) of the lifting hydraulic cylinder 24 (Fig. 1, 2, 4, 7-9) is fixed with a quick-release cylindrical swivel on the metal structure of the end support 15 (Fig. 1, 2, 4, 5, 8, 9). The specified quick-release swivel is formed by a pair of lugs 28 (Fig. 1, 4, 8, 9), fixed on the end support 15 (Fig. 1, 2, 4, 5, 8, 9), and the rod earring 27 (Fig. 4 , 7-9) of the lifting hydraulic cylinder 24 (Fig. 1, 2, 4, 7-9), in the coaxial holes of which the hinge pin 29 is inserted (Fig. 1). On the upper surface of the front end bearing plate 1 (Fig. 1-9), the nodes of the mechanism for holding the end support in the working position, including the rope winch 30 (Fig. 1, 2, 5, 7-9) (for example, with electric or manual drive) for fastening and changing the length of the retaining ropes 31 (Fig. 1, 2, 4, 7-9) of the power chain 32 (Fig. 1, 2, 4, 8, 9). On the upper surface of the right 3 (Fig. 1-9) or left 4 (Fig. 2, 4, 5, 9) side carrier plate, a lifting device 33 (Fig. 1, 2, 4, 5, 9) of the boom type ( for example, a crane-manipulator controlled by an operator using a portable wired or radio remote control) for carrying out loading and unloading operations when hanging or removing the transported cargo from the carrier-traction rope 23 (Fig. 1, 2). On the upper surface of all bearing plates, adjustable supports 34 are permanently fixed (Fig. 1, 2, 4, 5, 7-9) (for example, with height adjustment of the support using a hydraulic drive or with manual mechanical adjustment using a screw drive) to ensure the horizontal position of the bearing base of the end station, taking into account the unevenness of the site for its placement. The load from the weight of the end station and the operational forces generated during the operation of the cable system are transferred to the ground using the support soles 35 (Fig. 1, 3-9). Anchor devices 36 (Fig. 1-9) (for example, screw or piercing type [5]) are permanently fixed on the upper surface of the bearing plates to ensure the overall stability of the end station under conditions of action on the end support 15 (Fig. 1, 2, 4, 5, 8, 9) significant horizontal operational loads from the tension of the carrier-traction rope and the weight of the transported cargo, as well as from the action on the lifting device 33 (Fig. 1, 2, 4, 5, 9) of the operational overturning moment from the loaded cargo . Fastening devices are used to fix large-sized technological equipment in a stationary state in the transport position of the end station. The fixation of the end support 15 (Fig. 1, 2, 4, 5, 8, 9) is provided by a pair of rack 37 permanently fixed on the upper surface of the lower bearing plate 5 (Fig. 1-9) (Fig. 1, 2, 4, 5, 7-9), between the side posts of which there is free space for moving the lifting hydraulic cylinder 24 (Fig. 1, 2, 4.7 -9) in the vertical plane when it works to install the end support 15 (Fig. 1, 2, 4, 5, 8, 9) to the desired working position, and the collar 38 (Fig. 4, 5). The fixation of the end support 15 (Fig. 1, 2, 4, 5, 8, 9) when deploying the end station from the transport to the working position (and vice versa) is provided by paired quick-release locking rods 39 (Fig. 1, 2, 4, 5, 8, 9), each of which is attached at one end to a cylindrical spike 40 (Fig. 1, 4, 5, 8, 9), fixed (for example, by welding) on the side surface of the metal structure of the end support 15 (Fig. 1, 2 , 4, 5, 8, 9), and the other end is attached to the upper surface of the rear end bearing plate 2 (Fig. 1-9) using a swivel formed by two lugs 41 (Fig. 1, 2, 4, 5, 8 , 9) and hinge pin 42 (Fig. 1, 2, 4, 5, 8, 9). The fixation of the lifting device 33 (Fig. 1, 2, 4, 5, 9) provides a permanently fixed on the upper surface of the upper bearing plate 6 (Fig. 2, 3, 6-8) stand 43 (Fig. 2, 4, 9) and clamp 44 (Fig. 2, 4, 5, 9). The fixation of the lifting hydraulic cylinder 24 (Fig. 1, 2, 4, 7-9) provides permanently fixed on the upper surface of the lower bearing plate 5 (Fig. 1-9) rack 45 (Fig. 1, 2, 4, 7-9) and collar 46 (Fig. 1, 4, 7-9). Fixing each of the side carrier plates 3 (Fig. 1-9) and 4 (Fig. 2, 4, 5, 9) in a perpendicular direction relative to the upper carrier plate 6 (Fig. 2, 3, 6-8) when deploying the end station from the transport to the working position (and vice versa) are provided in pairs installed quick-detachable jibs 47 (Fig. 9), each of which is put on and fixed at one end (for example, with a union nut) on a cylindrical spike 48 (Fig. 2, 9), fixed (for example, by welding) on the side surface of the scarf 49 (Fig. 2, 9), fixed on the upper surface of the upper bearing plate 6 (Fig. 2, 3, 6-8), and the other end is put on and fixed on a cylindrical spike 50 (Fig. 1, 2, 9), fixed on the side surface of one of the side bearing plates - or right 3 (Fig. 1-9) , or left 4 (figure 2, 4, 5, 9).

The sequence of actions when deploying a fast mobile cable car, corresponding to the proposed invention, provides for the following operations.

An end station is delivered to one of the end points of the fast-erecting mobile cable car route in the transport position, i.e. in the form of a closed rectangular container (Fig. 3-5), and is installed on a dirt platform, and the longitudinal axis of the container corresponds to the longitudinal axis of the mobile cable car route. Delivery can be carried out by various means of transport, for example, by helicopter. Delivery of additional cargo containers is also carried out, containing additional equipment for the operation of the terminal station and maintenance personnel, in particular, a container with a diesel generator and a pumping unit to provide drives of mechanisms and devices with electric and hydraulic energy; a container with the necessary mounting equipment and fixtures, spare parts, carrier-traction rope, etc.; a container with materials and equipment for the deployment of accommodation for service personnel. The sequence of deploying the end station from the transport position to the working position is implemented in several stages. Covers 51 are preliminarily removed (Fig. 3), covering the holes in the bearing plates 1-6 for the passage of the working bodies of the anchor devices 36 (Fig. 1-9). At the first stage, the front end bearing plate 1 is unfolded (FIGS. 1-9). To do this, the lock connection is opened between the front end 1 (Fig. 1-9) and the upper 6 (Fig. 2, 3, 6-8) bearing plates, formed by several pairs of mutually conjugated U-shaped 11 (Fig. 1-9) and flat 12 (Fig. 1-9) lugs by removing the hinge pins 13 (Fig. 1-9). Then the front end bearing plate 1 is rotated (Fig. 1-9) relative to the axis of the swivel joint A-A (Fig. 1), and to ensure slow smooth rotation and lowering of the plate to the ground, a removable power chain hoist is used, the ends of which are fixed on the front end 1 (Fig. 1-9) and upper 6 (Fig. 2, 3, 6-8) carrier plates. The side view of the end station after the first stage of deployment is shown in FIG. 6. At the second stage, the rear end bearing plate 2 is unfolded (Fig. 1-9). To do this, the disclosure is made by removing the hinge pins 13 (Fig. 1-9) of two locking joints formed by several pairs of mutually conjugated U-shaped 11 (Fig. 1-9) and flat 12 (Fig. 1-9) lugs, - lock connection between the lower 5 (Fig. 1-9) and the right side 3 (Fig. 1-9) bearing plates, as well as the lock connection between the lower 5 (Fig. 1-9) and the left side 4 (Fig. 2, 4, 5, 9) with carrier plates. Then the rear end bearing plate 2 (Fig. 1-9) is rotated (together with the bearing plates 3 (Fig. 1-9), 4 (Fig. 2, 4, 5, 9) and 6 (Fig. 2) attached to it , 3, 6-8)) relative to the axis of the swivel B-B (Fig. 1). The end support 15 (Fig. 1, 2, 4, 5, 8, 9) is previously detached from the paired rack 37 (Fig. 1, 2, 4, 5, 7-9) by removing the clamp 38 (Fig. 4, 5 ). To ensure the rotation and lowering of the plate to the ground, two removable power chain hoists are used, the operation of which is synchronized. Power chain hoist, providing rotation of the rear end bearing plate 2 (Fig. 1-9), with one of its ends is fixed on the upper 6 (Fig. 2, 3, 6-8) bearing plate, and the second - to a remote anchor device fixed on the ground or to a previously prepared earthen anchor structure or to the base of a suitable tree trunk. The second power chain hoist, which keeps the carrier plate from abrupt overturning and, thus, providing slow speed and smoothness of turning and lowering the plate to the ground, is similarly attached to the top 6 (Fig. 2, 3, 6-8) of the carrier plate, and the second - to another remote anchor device. The side view of the end station after the second stage of deployment is shown in FIG. 7. At the third stage, the upper carrier plate 6 is unfolded (Fig. 2, 3, 6-8). To do this, disclosure is made by removing the hinge pins 13 (Fig. 1-9) of two locking joints formed by several pairs of mutually conjugated U-shaped 11 (Fig. 1-9) and flat 12 (Fig. 1-9) lugs, -lock connections between the rear end 2 (Fig. 1-9) and the right side 3 (Fig. 1-9) bearing plates, as well as the locking connection between the rear end 2 (Fig. 1-9) and the left side 4 (Fig. 2, 4, 5, 9) with carrier plates. Then the upper carrier plate 6 (Fig. 2, 3, 6-8) is rotated (together with side carrier plates 3 (Fig. 1-9) and 4 (Fig. 2, 4, 5, 9) attached to it) relative to swivel axis C-C (Fig. 1). To ensure the rotation and lowering of the plate to the ground, two removable power chain hoists are used, the operation of which is synchronized. The power chain hoist, which ensures the rotation of the upper carrier plate 6 (Fig. 2, 3, 6-8), with one end is fixed on the upper 6 (Fig. 2, 3, 6-8) carrier plate, and the second - to the remote fixed on the ground anchor device. The second power chain hoist, which keeps the carrier plate from abrupt overturning and, thus, ensuring slow speed and smoothness of turning and lowering the plate to the ground, is similarly attached to the upper carrier plate 6 at one end (Fig. 2, 3, 6-8), and the second - to another remote anchor device. The side view of the end station after the third stage of deployment is shown in FIG. 8. At the fourth stage, the side bearing plates 3 (Fig. 1-9) and 4 (Fig. 2, 4, 5, 9) are unfolded. When unfolding the right side carrier plate 3 (Fig. 1-9), both jibs 47 (Fig. 9) are removed from the cylindrical spikes 48 (Fig. 2, 9) and 50 (Fig. 1, 2, 9). Then the right side bearing plate 3 is rotated (Fig. 1-9) relative to the axis of the swivel joint D-D (Fig. 1), and to ensure slow smooth rotation and lowering of the plate to the ground, one removable power chain hoist is used, the ends of which are fixed on the side bearing plates 3 (Fig. 1-9) and 4 (Fig. 2, 4, 5, 9). The side view of the end station during the fourth stage of deployment after unfolding the right side carrier plate 3 (FIGS. 1-9) is shown in FIG. 9. Similarly, the left side carrier plate 4 is unfolded (Fig. 2, 4, 5, 9) by turning it relative to the axis of the swivel E-E (Fig. 1). Previously, the lifting device 33 (Fig. 1, 2, 4, 5, 9) is detached from the rack 43 (Fig. 2, 4, 9) by removing the clamp 44 (Fig. 2, 4, 5, 9). At the fifth stage of deployment, a number of mounting operations are performed, including such as: 1) installing all the bearing plates in a single horizontal plane by changing the height of the adjustable supports 34 (Fig. 1, 2, 4, 5, 7-9); 2) fixing on the ground of the resulting single bearing base of the end station using anchor devices 36 (Fig. 1-9); 3) detachment of the lifting hydraulic cylinder 24 (Fig. 1, 2, 4, 7-9) from the rack 45 (Fig. 1, 2, 4, 7-9) by removing the clamp 46 (Fig. 1, 4, 7-9) ; 4) creating a hinged connection between the lifting hydraulic cylinder 24 (Fig. 1, 2, 4, 7-9) and the end support 15 (Fig. 1, 2, 4, 5, 8, 9) by installing and fixing in the axial direction of the hinge pin 29 (Fig. 1) into the coaxial holes of the earring of the rod 27 (Fig. 4, 7-9) and lugs 28 (Fig. 1, 4, 8, 9); 5) connection of power cables and hydraulic lines from the drives of the end station mechanisms to the electrical and hydraulic outputs of the diesel generator and pumping unit; 6) removal of the locking rods 39 (Fig. 1, 2, 4, 5, 8, 9), fixing the end support 15 (Fig. 1, 2, 4, 5, 8, 9) in the transport position, by removing them from the cylindrical spike 40 (Fig. 1, 4, 5, 8, 9); 7) unfolding the end support 15 (Fig. 1, 2, 4, 5, 8, 9), for example, by extending the telescopic section 16 (Fig. 1, 4, 5, 8, 9) using the hydraulic cylinder 52 (Fig. 4 , 5, 8, 9); 8) hanging the carrier-traction rope 23 (Fig. 1, 2), for example, using a helicopter, including joining the ends of the rope with a quick-release connector and hanging cargo trucks equipped with load gripping bodies to hold the transported cargo; 9) installation of the end support 15 (Fig. 1,2,4,5,8,9) in the required working position and the orientation of the rope pulley 17 (Fig. 1, 2, 4, 5, 8, 9), taking into account the sagging of the carrier traction rope 23 (Fig. 1, 2); 10) tension of the carrier-traction rope 23 (Fig. 1, 2) using a rope winch 30 (Fig. 1, 2, 5, 7-9), holding rope 31 (Fig. 1, 2, 4, 7-9) and power chain hoist 32 (Fig. 1, 2, 4, 8, 9). The dismantling of the end station from the working (deployed) position to the transport position is carried out in the reverse order.

The technical and economic results formulated above, which can be obtained using the proposed invention, are achieved due to the minimum required volume, labor intensity and duration of installation work and the minimum number of installation personnel when deploying a mobile cable car due to the high degree of factory readiness of a pre-fixed and well-fitted in accordance with the required installation and connecting dimensions of the main process equipment, which does not require additional installation in the field. Also, the achievement of the declared technical and economic result associated with the expansion of the possibility of using the proposed mobile cable car in hard-to-reach and (or) in advance unequipped areas with difficult natural terrain, is associated with ample transport capabilities for the delivery of end stations of the proposed design, including using helicopters. When using an end support up to 8 ... 9 m long (height of a 3-storey building), the approximate weight of the container with the end station will be up to 8 tons, i.e. cargo helicopters of the Mi-6 and Mi-10 types can be used for its transportation (permissible weight of cargo on an external sling is 8 tons). When using an end support with a length of 11...18 m (height of a 4...6-storey building), the approximate weight of the container with the end station will be from 11 to 18 tons, i.e. for its transportation, cargo helicopters of the Mi-26 type and its modifications Mi-26K, Mi-26T, Mi-26TM can be used (permissible weight of cargo on an external sling is 20 tons).
