Description

Technical Field

[0001] The present invention relates to the field of transportation equipment. More specifically, the present invention relates to a special transport vehicle for snow-making pipelines on alpine ski slopes. Background Art

[0002] With the booming development of the international ice and snow industry, the planning and design of ski slopes in ski resorts show a trend of diversity, professionalism, and high difficulty. To meet the diverse snow slope requirements, the construction of ski resorts usually needs to be located in high-steep mountainous areas. Among them, the transportation of large construction materials such as snow-making pipelines is the key and difficult process in construction in alpine environments.

[0003] In actual construction, although the traditional transportation method of combining manpower and animal power can adapt to the high-steep mountainous environment to a certain extent, it has disadvantages such as limited load capacity and low transportation efficiency; there are also solutions in the prior art that use cableway transportation for snow-making pipeline transportation. However, the erection of the cableway in the early stage requires the participation of geological surveys and structural engineers in the design. It takes at least 2-4 weeks to erect each kilometer of the cableway, and the erection cost per kilometer of the cableway reaches hundreds of thousands of yuan. Especially for high-altitude and long-distance transportation, there are problems such as long construction periods and high erection costs. In addition, after the erection is completed, the transportation route of the cableway is fixed and cannot be adjusted arbitrarily. Secondary transportation equipment and processes need to be added to accurately move each section of the snow-making pipeline to the corresponding construction operation surface, resulting in insufficient transportation flexibility and being unable to be well applied to long-line snow-making pipeline transportation projects with complex terrain conditions.

[0004] To solve the above problems, it is necessary to design a special transport vehicle for snow-making pipelines on alpine ski slopes to improve the pipeline transportation efficiency and environmental adaptability under the condition of ensuring the transportation quality.

[0020] The following further describes the present invention in detail with reference to the drawings so that those skilled in the art can implement it according to the description in the specification.

[0021] It should be noted that the experimental methods described in the following implementation schemes are all conventional methods unless otherwise specified, and the reagents and materials can be obtained from commercial channels unless otherwise specified; in the description of the present invention, the orientation or positional relationship indicated by terms such as "transverse", "longitudinal", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the present invention.

[0022] As Figures 1-4 shown, the present invention provides a special transport vehicle for snow-making pipelines on alpine ski slopes, including a plurality of transport units, which are sequentially connected in series along the transport direction through a connecting mechanism, and both ends of the connecting mechanism are hinged to adjacent transport units in a vertical plane and a horizontal plane. Any transport unit includes: Traveling mechanism, which includes a chassis bracket 11; two sets of traveling wheels 12, which are oppositely arranged on both sides of the chassis bracket 11. Any one set of traveling wheels 12 includes a plurality of traveling wheels 12 arranged at intervals along the length direction of the chassis bracket 11. An installation groove is radially formed on the wheel surface of any one traveling wheel 12; a first driving mechanism, which is arranged on the chassis bracket 11 and is used to drive the traveling wheel 12 located at the front end of the chassis bracket 11 to rotate; two crawlers 13, which are correspondingly arranged with the two sets of traveling wheels 12. Any one crawler 13 is cooperatively sleeved outside the corresponding set of traveling wheels 12 and is in transmission connection with it to form a flexible chain link. A plurality of through holes 14 are arranged at intervals along the circumferential direction of the crawler 13. Any one through hole 14 penetrates the inner and outer sides of the crawler 13 along the radial direction. When the traveling wheel 12 rotates to the position where the opening of the installation groove is vertically downward, the installation groove is arranged opposite to the through hole 14 on the crawler 13; a plurality of parking devices, which are correspondingly arranged on each traveling wheel 12. Any one parking device is arranged in the installation groove of the corresponding traveling wheel 12. The parking device includes a parking nail 15, whose tip faces outward and moves along the installation groove under the action of a second driving mechanism; Transportation platform 3, which is fixedly installed on the top of the chassis bracket 11 and is equipped with a wind direction and wind speed measuring device; Rotary platform 4, which is rotatably arranged on the top of the transportation platform 3 through a rotary mechanism. The rotation axis of the rotary mechanism is vertically arranged; One or more limiting devices, which are arranged at intervals along the length direction of the rotary platform 4 on its top. Each limiting device is used to support the same snow-making pipeline segment 7 and limit its lateral, longitudinal and vertical displacements; Controller, which is electrically connected to the traveling mechanism, the wind direction and wind speed measuring device, and the rotary mechanism.

[0023] In the above technical solution, multiple transportation units are sequentially connected in series to form a long-strip transportation structure. Under the condition of the same load capacity (the number of snow-making pipelines carried), the body width of a single transportation unit can be significantly reduced compared to the conventional transport vehicle structure, so as to better adapt to the narrow terrain and limited walking space in the mountains. On this basis, two adjacent transportation units can rotate relative to each other with the connection point of the connecting mechanism as the center in both the horizontal lateral direction (the width direction of the transport platform) and the vertical direction. Therefore, it can well adapt to the bumps that occur during the walking of different front and rear transportation units. That is, the vibrations in the front and rear and left and right directions when the front transportation unit adapts to the uneven road surface below will not affect the walking stability of the rear transportation unit, and it also avoids the fatigue loss of the connecting mechanism caused by the vibration of a single transportation unit during the walking of the long-strip transportation structure. Moreover, each transportation unit is equipped with an independent walking mechanism. During the overall walking of the transport vehicle, when facing narrow and rugged terrain conditions (such as U-shaped and S-shaped passages), the walking directions of each transportation unit can be controlled separately to achieve flexible adaptive steering. For example, when facing a sharp turn, the front-end transportation unit first turns and rotates adaptively relative to the horizontal hinge point of the connecting mechanism, and the rear transportation unit still walks in the original direction and turns separately when it walks to the turning node (the position where the front-end transportation unit turns), and then it can smoothly pass through this turning section. The above setting form of the connecting mechanism enables the long-strip transportation structure to well adapt to various different mountain terrain conditions and ensure the stability and safety of transportation.

[0024] For a single transportation unit, a crawler-type walking mechanism is adopted, and a parking device is additionally arranged between the walking wheel 12 and the crawler 13, which can be adapted to the above crawler-type walking mechanism. That is, in the walking mode, the parking pin 15 is in the initial position in the installation groove and rotates synchronously with the walking wheel 12, and it will not be pressed during the walking process and will not interfere with the normal operation of the walking wheel 12. By the controller reading the working state of the first driving mechanism or the walking wheel 12 in real time, the real-time rotation angle of the installation groove on the walking wheel 12 can be analyzed. In the parking mode, when controlling the working state of the first driving mechanism and making the first driving mechanism completely brake and stop, the installation groove just rotates with the walking wheel 12 to the position where the opening is vertically downward. Thus, when the walking mechanism stops walking, the installation groove is in the state where the opening is vertically downward and is set opposite to the through hole 14 on the crawler 13. At this time, the second driving mechanism of the parking device is started, so that the parking pin 15 passes through the installation groove and the corresponding through hole 14 in sequence and anchors into the ground layer, realizing the double locking of the walking wheel 12 and the crawler 13, and ensuring the stability and environmental adaptability of the walking mechanism in the parking mode.

[0025] The limiting device is used to achieve the stable loading of the snow-making pipeline section 7 on the slewing platform 4. When the slewing platform 4 rotates relative to the transport platform 3, the corresponding snow-making pipeline section 7 rotates synchronously with the slewing platform 4 to adjust the loading attitude of the snow-making pipeline section 7, so as to better adapt to different mountain terrain conditions and improve the passing ability of the transport vehicle on small-radius lines.

[0026] A wind direction and wind speed measuring device is provided on the transport platform 3, which can measure the wind direction and wind speed at the corresponding transport unit in real time. Since the snow-making pipeline section 7 is a tubular structure with an axial through hole, the controller can adjust the rotation angle of the slewing platform 4 according to the real-time wind direction, so that the axis of the carried snow-making pipeline section 7 is aligned with the current wind direction. Thus, the influence of wind resistance on the driving power of the transport unit during transportation is minimized as much as possible, achieving the purpose of power saving and extended battery life. At the same time, it also avoids the situation where a large area of the side wall of the snow-making pipeline section is in the windward side in a strong wind environment, reducing the risk of the transport unit tipping over under the influence of wind. In addition, the controller can also judge the safety risk of walking according to the real-time wind speed and conduct linkage control on the working state of the walking mechanism accordingly. Specifically, when the measured wind speed exceeds the set threshold, it directly controls the switching to the parking mode for parking and parking actions, and the stabilizer is used to assist the brake of the first driving mechanism to achieve stable parking, further enhancing the adaptability of the transport vehicle to harsh environments.

[0027] In this embodiment, the first driving mechanism adopts an electric motor, which is equipped with a power battery, a reduction box, a brake, etc. An encoder is provided on the output shaft of the electric motor or the rotating shaft of the walking wheel. The controller is electrically connected to the encoder. By setting the installation direction of the installation groove as the rotation zero point of the walking wheel, the real-time rotation angle of the installation groove can be analyzed and calculated or directly read through the rotation position of the output shaft of the electric motor. The second driving mechanism can be selected from conventional pushing devices such as electric push rods. The slewing mechanism can be selected as a slewing motor, which is coaxially arranged with the slewing platform. The controllers of each transport unit can achieve data transmission through wired / wireless means and jointly constitute a control system. Its total control terminal is set at the transport unit at the forefront of the transport direction. A control room is provided at the front end of the transport platform of this transport unit, and a seat and a control panel are arranged inside. The control panel is electrically connected to the total control terminal. Construction personnel can manually control the walking state of the transport vehicle in the control room, or can also control the transport vehicle to walk automatically through the walking route built in the control system, realizing unmanned, intelligent, and automated transportation.

[0028] In another technical solution, for the special transport vehicle for alpine snowmaking pipeline, a plurality of connecting mechanisms are arranged at intervals in the width direction between two adjacent transport unit members. Any one of the connecting mechanisms includes a viscous damper 21. One end of the viscous damper is provided with a vertical hinge seat 22 which is hinged to the adjacent transport platform 3 in a matching manner and the hinge axis is arranged along the width direction of the transport platform 3. The other end is provided with a horizontal hinge seat 23 which is hinged to the adjacent transport platform 3 in a matching manner and the hinge axis is arranged along the height direction of the transport platform 3.

[0029] Among them, hinge seats corresponding to the vertical hinge seat 22 and the horizontal hinge seat 23 of the connecting mechanism are respectively arranged at the end parts of each transport platform 3. The corresponding hinge seats are connected by a pin shaft (hinge axis). The connecting mechanism body is set as the viscous damper 21. Thus, during the start, travel and stop of the traveling mechanism, the impact force generated between different transport units due to factors such as uneven road surface and incomplete synchronous movement can be buffered and consumed, making this towed transport unit connection structure have better durability and stability. In this embodiment, each hinge seat can be set in the form of an ear plate, and a pin hole is arranged in the middle of the ear plate for installing the corresponding hinge axis.

[0030] In another technical solution, for the special transport vehicle for alpine snowmaking pipeline, a plurality of first convex blocks 16 are arranged at intervals along the circumferential direction on the outer side of the traveling wheel 12, and a plurality of second convex blocks 17 are arranged at intervals along the circumferential direction on the inner side of the crawler belt 13. The traveling wheel 12 and the crawler belt 13 are connected in a meshing manner through the first convex blocks 16 and the second convex blocks 17. The structure of the first convex block 16 matches the groove structure between two adjacent second convex blocks 17 and is engaged and clamped therewith. The structure of the second convex block 17 matches the groove structure between two adjacent first convex blocks 16 and is engaged and clamped therewith. This meshing transmission structure makes the travel of the crawler-type traveling mechanism more accurate and stable. At the same time, the first convex blocks 16 do not need to be completely inserted into the corresponding groove structures, leaving enough buffer space for the vibration during travel and also reserving a certain space for the installation and movement of the parking studs 15.

[0031] In another technical solution, for the special transport vehicle for alpine snowmaking pipeline, the through hole 14 is arranged between two adjacent second convex blocks 17 and matches the size of the parking stud 15, and the opening of the installation groove is arranged on the first convex block 16.

[0032] Specifically, each through hole 14 is set at the midpoint between two adjacent second protrusions 17, and correspondingly, the opening of the installation slot is set at the midpoint of the end face of the first protrusion 16, so as to facilitate the precise alignment of the opening of the installation slot and the through hole 14. The number and specific position of the through holes 14 are designed according to the distribution of the first and second protrusions 17, so as to meet the following conditions: whenever the installation slot rotates to the position where the opening faces vertically downward, a through hole 14 is set on the surface of the crawler 13 facing it, or a through hole 14 can be set between every two second protrusions 17. In the walking mode, the parking nail 15 is in the initial position, and its tip can be set out of the installation slot. Since there is a certain space between the first protrusion 16 and the corresponding bottom of the groove structure and it does not directly contact the force-bearing surface, the parking nail that passes out of the installation slot for a certain distance (cannot extend into the through hole) will not affect the normal operation of the crawler wheel in the non-parking state; in the parking mode, the parking nail 15 can quickly pass through the corresponding through hole 14 and anchor into the stratum, so as to achieve efficient and reliable parking.

[0033] In another technical solution, the alpine snow track snowmaking pipeline dedicated transport vehicle has spikes 18 arranged at intervals along the circumferential direction on the outer side of the track 13. The track 13 can be a metal spike track, thereby enhancing the gripping ability of the walking mechanism during walking and ensuring the walking stability of the transport unit in harsh environments.

[0034] In another technical solution, in the above-mentioned special transport vehicle for snowmaking pipelines on alpine ski slopes, the parking nail 15 is threadedly connected with the installation groove, and the second driving mechanism is a linear driving mechanism, which is fixed in the installation groove and the pushing end is fixedly connected with the end of the parking nail 15 away from the tip. Among them, the installation groove is provided with an internal thread, and the parking nail 15 is provided with an external thread, and the two are rotatably connected through thread cooperation, so that in the parking mode, when the second driving mechanism pushes the parking nail 15 to move vertically downward, the parking nail 15 rotates while moving downward, forming a rotary drilling structure, so that the parking nail can be anchored in the formation more easily, and no higher power requirements are set for the driving force of the second driving mechanism.

[0035] In another technical solution, in the dedicated transport vehicle for snowmaking pipelines on alpine ski slopes, the first driving mechanism comprises two driving motors, which are arranged corresponding to the two sets of walking wheels 12, and the output shaft of any driving motor is connected to the rotating shaft of the corresponding walking wheel 12 through a coupling, and the driving motor slides along the width direction of the chassis bracket 11 under the action of the third driving mechanism; when the transport unit switches to the driven walking mode, the driving motor disengages from the coupling under the action of the third driving mechanism.

[0036] In the above technical solution, the two groups of walking wheels 12 are driven by different driving motors, so that the controller can adjust the speed of each driving motor individually to realize the steering (differential speed adjustment) of the crawler walking mechanism. The walking mode of the transport unit is divided into an active walking mode and a driven walking mode. The transport unit located at the front end of the transport direction is always in the active walking mode, and the transport unit located at the rear can switch between the active walking mode and the driven walking mode. In the active walking mode, the output shaft of the driving motor is inserted into the coupling and drives the corresponding walking wheel to rotate; in the driven walking mode, the output shaft of the driving motor is disengaged from the coupling, and the walking wheel is not actively driven, but rotates adaptively with the movement of the crawler, that is, the first driving mechanism does not work. Specifically, the third driving mechanism can use a hydraulic push rod, which is electrically connected to the controller. The chassis bracket is provided with a moving track adapted to the two driving motors of the first driving mechanism. The third driving mechanism is located in the middle of the moving track, which is used to control each driving motor to approach or move away from the corresponding coupling. In actual work, the above-mentioned transport unit located at the rear can select the driven walking mode in the conventional straight-line walking state, that is, the transport unit located at the rear is dragged by the frontmost transport unit for walking. At this time, the crawler track of the rear transport unit walks drivenly and drives the walking wheels to rotate. It is not connected to the first drive mechanism in transmission and will not interfere with its (inherent structure); when walking on a non-straight path, the transport unit located at the rear is switched to the active walking mode, and the controller controls the first drive mechanism of each transport unit to turn at the appropriate time according to the set walking route and real-time walking speed, so as to better adapt to safe and stable transportation under different terrain conditions.

[0037] In another technical solution, in the alpine snow slope snowmaking pipeline dedicated transport vehicle, the limiting device includes a limiting plate 51, and the two sides of the limiting plate are respectively provided with upwardly protruding limiting teeth 52 along the length direction, and the two ends of the limiting plate 51 are respectively provided with binding plates 53, and the middle part is provided with binding holes 54; one or more groups of limiters are arranged at intervals along the length direction of the limiting plate 51 and correspond to the number of snowmaking pipeline segments 7 loaded on the transport unit, and any group of limiters includes two limit blocks, which are arranged along the limiting plate 5 1 are spaced apart and arranged relatively in the longitudinal direction, any limit block includes a wedge block 55, which is supported on the limit plate 51 and clamped between the limit teeth 52 on both sides thereof, and clamping blocks 56 are respectively fixed on both sides of the wedge block 55, which are matched and clamped between adjacent protrusions of the limit teeth 52 on the same side, and the wedge-shaped inclined surfaces of the two limit blocks are adjacent and arranged relatively; a binding belt 57, both ends of which are respectively connected to the binding holes 54 of the binding plate 53 and are used to press each snowmaking pipeline segment 7 between the corresponding two limit blocks.

[0038] Among them, one or more snow-making pipeline segments can be loaded on the same limiting device. Each snow-making pipeline segment 7 is limited in the length direction of the limiting plate 51 by two limiting blocks in the same group. By cooperating with the binding belt 57 to press downwards, the corresponding snow-making pipeline segment 7 can be fixed on the limiting device. By changing the clamping position of the clamping block 56 and the limiting tooth 52, the distance between the two limiting blocks (wedge-shaped blocks 55) in the same group can be adjusted. The limiting teeth 52 are continuously arranged along the length direction of the limiting plate 51 to form a rack structure. The size of the rack (the length and spacing of each protrusion) is designed according to the diameter of each snow-making pipeline segment 7, so that by changing the distance between the two limiting blocks in the switching limiter (that is, changing the position of the limiting teeth into which the limiting block is inserted), the sizes of various required snow-making pipeline segments can be adapted. In this embodiment, two clamping blocks 56 are provided on each side of the wedge-shaped block 55, and it can be adaptively clamped between three adjacent protrusions of the limiting teeth 52, strengthening the connection stability between the limiting block and the limiting plate.

[0039] In another technical solution, for the special transport vehicle for alpine snowmaking pipeline, a limiting groove is provided on the wedge-shaped inclined surface of the limiting block, and a limiting spring 58 is arranged inside it. The limiting spring 58 is arranged along the length direction of the limiting groove and one end is fixed at the bottom of the limiting groove. The other end of the limiting spring 58 is fixedly provided with a cushion block 59, which is slidably connected with the limiting groove in cooperation. Thus, elastic limiting support for the snow-making pipeline segment 7 located between the two limiting blocks is realized by the limiter. On the one hand, when the snow-making pipeline segment 7 sways due to the vibration of the transport unit body during transportation, the cushion blocks 59 on both sides and the limiting spring 58 can cooperate for buffering; on the other hand, the cushion block 59 is in a springed-up state before the snow-making pipeline segment 7 is loaded, that is, the cushion block 59 extends out of the limiting groove. After the snow-making pipeline segment 7 is loaded, the cushion block 59 is pressed into the limiting groove by a certain distance, and the limiting spring 58 is in a compressed state, so that the cushion block 59 forms an elastic support structure, which can adapt to the dimensional error between the limiter and the snow-making pipeline segment. When the distance between the limiting blocks in the same group actually installed is not completely adapted to the size of the snow-making pipeline segment 7 (there are minor design and installation errors), the cushion block 59 and the limiting spring 58 can cooperate to automatically adapt to the above-mentioned dimensional error, realizing adaptive and stable limiting support for the snow-making pipeline segment.

[0040] In another technical solution, for the special transport vehicle for snow-making pipelines on alpine ski slopes, the transport unit further includes a protection device, which corresponds to the number of snow-making pipeline segments 7 loaded in the current transport unit. Any protection device includes an outer sleeve 61, which is fitted and sleeved outside the corresponding snow-making pipeline segment 7. At both sides of the bottom of the outer sleeve 61, there are respectively card slots 62 corresponding to the cushion blocks 59; an inner sleeve 63, which is located inside the snow-making pipeline segment 7 and one end of which is integrally connected with the outer sleeve 61 at the end of the snow-making pipeline segment 7. The inner sleeve 63 and the other end of the outer sleeve 61 both extend out of the end face of the snow-making pipeline segment 7 and form an annular groove; an annular plug 64, which is fitted and sleeved in the annular groove and presses the end face of the snow-making pipeline segment 7. The annular plug 64 is fixedly connected with the inner sleeve 63 and the outer sleeve 61 through a locking member 65.

[0041] In the above technical solution, as Figure 2 , 4 shown, the outer sleeve 61 and the inner sleeve 63 are of an integrated structure. The inner diameter of the outer sleeve 61 is adapted to the outer diameter of the snow-making pipeline segment 7, and the outer diameter of the inner sleeve 63 is less than or equal to the inner diameter of the snow-making pipeline segment 7. After installation, the protection device covers and wraps the corresponding snow-making pipeline segment 7, realizing the all-round protection of the snow-making pipeline segment with a heat-insulating layer, avoiding the influence of the relatively harsh alpine environment on the quality of the pipeline itself during transportation, and effectively preventing the pipeline from being damaged by collision, deformed or impurities entering the pipeline during transportation. The inner sleeve 63 does not need to fit with the inner side wall of the snow-making pipeline, realizing the avoidance and protection of additional structures (such as heating devices, etc.) that may be additionally installed inside the snow-making pipeline segment. And since the inner cavity of the inner sleeve 63 still forms an axially penetrating space, it does not affect the angle adjustment of the rotary platform 4 with the wind direction, enabling the orientation of the snow-making pipeline segment 7 to adapt to the wind direction to reduce wind resistance. There are also card slots 62 corresponding to the cushion blocks 59 on the outer sleeve 61. When loading the snow-making pipeline segment 7, the smooth side wall of the pipe section can be used to press the two-side cushion blocks 59 downward first, and the axial positions of its card slots 62 and the cushion blocks 59 are adjusted. Then, the above-mentioned snow-making pipeline segment 7 is rotated to gradually move the card slots 62 closer to the position of the cushion blocks 59 until the cushion blocks 59 automatically pop out under the action of the limit spring 58 and are stuck into the corresponding card slots 62, strengthening the limit reliability and stability of the limiter for the snow-making pipeline segment. Specifically, the locking member 65 includes a plurality of bolts, which are arranged at intervals along the circumference of the annular plug 64. There are radially installed holes on the annular plug 64, the inner sleeve 63 and the outer sleeve 61 that communicate with each other. The radially installed holes on the annular plug 64 and the outer sleeve 61 are through holes. Any bolt passes through the radially installed holes on the outer sleeve 61 and the annular plug 64 and is locked in the radially installed hole of the inner sleeve 63, realizing the quick and convenient disassembly and assembly of the protection device and the corresponding snow-making pipeline segment.

It can be fully applied to various fields suitable for the present invention. For those familiar with the field, additional modifications can be easily made. Therefore, without departing from the general concept defined by the claims and the equivalent scope, the present invention is not limited to the specific details and the examples shown and described herein.
