Description

Technical Field

[0001] The utility model relates to the technical field of rail transport vehicles, in particular to a self-locking transport device for double tracks. Background Art

[0002] With the development and maturity of technology, most existing photovoltaic systems are centralized mountain-based installations, increasingly located in mountainous areas with steep slopes and complex terrain. Consequently, the increasing slope and complex and diverse topography of the mountains significantly increase the difficulty of transporting photovoltaic brackets and component materials to the mountainside installation site. Furthermore, the large operating area and difficult on-site management make the bulk material handling process highly susceptible to damage to the finished pile foundations from materials such as purlin brackets, as well as damage to the bracket materials themselves. Furthermore, after construction, the recovery of mountainside waste and construction debris is fraught with challenges, requiring significant labor and making transportation difficult and dangerous.

[0003] At present, in order to facilitate transportation, workers generally use rail transport vehicles for transportation operations. Although existing rail transport vehicles can improve transportation efficiency, they still have the following shortcomings in actual use:

[0004] 1. Most of the tracks are single-track or double-track without fixed crossbeams. The transport vehicle is easily affected by the slope of the mountain and bumps during the traction process. In serious cases, it may roll over, posing a great safety risk.

[0005] 2. The overall structure of the transport vehicle is complex, difficult to assemble on site, difficult to utilize on-site materials, and has poor adaptability.

[0006] 3. Transport vehicles generally do not have a self-locking function, or the self-locking equipment is complex, the self-locking equipment is expensive and difficult to maintain. Once the vehicle slips during transportation, it will cause casualties and product damage near the track, further reducing safety. Utility Model Content

[0024] In order to make the purpose, features, and advantages of the present invention more obvious and easy to understand, the technical solutions of the present invention will be clearly and completely described below in conjunction with the drawings in the specific embodiments. Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of them. Based on the embodiments in this patent, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this patent.

[0025] Please refer to the attached Figure 1-5, combined with a specific embodiment, it is explained as follows: The utility model is a self-locking transport device for double tracks, including a transport track 1, which is laid on the roadbed through a number of track beams 2 arranged at intervals. Combined with the existing track laying technology, the track beams 2 are laid on the roadbed through pile foundations 13, pile foundation columns 14 and column connectors 15, and the transport track 1 and the track beams 2 are connected by through bolts. The width of the transport track 1 can be adjusted according to local conditions, and it can be laid after selecting a suitable position on site; at the same time, in order to facilitate the staff to obtain materials on site, purlins can be used for both the transport track 1 and the track beams 2. Through the above structure, the staff can continue or disassemble at any time, and the disassembled materials can be reused on site.

[0026] A winch 3 is provided on the top of the transport track 1, and the winch 3 is connected to a transport trolley 5 arranged on the transport track 1 through its traction rope 4; a locking hook 6 is provided on the bottom side of the transport trolley 5 that cooperates with the track beam 2, and the hook body of the locking hook 6 is rotatably connected to the bottom side of the transport trolley 5, and the hook head of the locking hook 6 faces the winch 3, and the opening of the hook head faces the track beam 2. The locking hook 6 is connected to a connecting ring 8 fixedly sleeved on the traction rope 4 through a connecting rope 7, and the specific installation position of this connecting ring 8 can be determined on site through experiments; the traction rope 4 can pull up or lower the locking hook 6 through the connecting rope 7 and the connecting ring 8, so that the locking hook 6 can remain separated from the track beam 2 or can be hung on the track beam 2.

[0027] Specifically, the transport vehicle 5 includes a chassis 501 with a frame structure. A truck bed is provided on the top side of the chassis 501. Wheels 504 that cooperate with the transport track 1 are provided on the bottom side of the chassis 501. The hook body of the locking hook 6 is rotatably connected to the supporting crossbeam 5011 of the chassis 501 through a connecting piece. The truck bed includes a bottom frame 502 and two side frames 503. The bottom frame 502 is fixed to the bottom end of the chassis 501. The two side frames 503 are fixed to both sides of the chassis 501, and the bottom ends of the two side frames 503 are respectively connected to the two ends of the bottom frame 502. The overall structure of the above-mentioned transport vehicle 5 is simple and can be assembled using on-site materials, which is convenient for workers to assemble. At the same time, workers can modify it at any time according to transportation requirements and on-site conditions, and it has good adaptability.

[0028] The operating principle of the present invention is as follows: Before the transport vehicle 5 begins to travel, the traction rope 4 bends toward the road surface due to the weight of the locking hook 6. At this point, the locking hook 6 can hook onto the track beam 2, thereby ensuring that the transport vehicle 5 stops. When the transport vehicle 5 begins to travel, the winch 3 begins to operate, straightening the traction rope 4. At this point, the locking hook 6, under the action of the traction force, separates from the track beam 2 and clings to the bottom of the transport vehicle 5, allowing the transport vehicle 5 to move upward. During travel, when the transport vehicle 5 stops for loading or unloading or descends, the traction rope 4 remains taut and the locking hook 6 remains pulled up. If the traction rope 4 breaks during this process, the locking hook 6, under the action of its own weight, will drop toward the road surface and hook onto the track beam 2, achieving a self-locking stop. This transport device utilizes the winch 3 to pull the transport vehicle 5, enabling the upward transport of installation materials and the downward recovery of installation waste or construction debris, greatly improving construction, installation, and transportation efficiency.

[0029] In one embodiment, the top of the side frame 503 is a column 5031, on which a clamp 9 is provided, and a reinforcing diagonal beam A10 is provided inside the side frame 503. The design of the reinforcing diagonal beam A10 can increase the body strength of the transport vehicle 5. In addition, the clamp 9 installed on the column 5031 can rotate 360 ​​degrees and move up and down. When transporting photovoltaic modules, the clamp 9 can be adjusted up and down according to the stacking height of the modules and rotated so that the long side of the clamp 9 is pressed against the upper edge of the module. In addition, cardboard or the like can be padded on the edge of the module to prevent the modules from being bumped, broken, or sliding left and right during transportation.

[0030] Specifically, when installation materials need to be placed horizontally in front of pillars 5031, ropes or wires are threaded through the pairs of holes in the clamps 9 and connected to the bundled installation materials, thereby preventing the installation materials from sliding left and right or slipping out from the side due to bumps. Furthermore, after construction is completed at the top of the mountain, bulk bags are used to collect leftover materials, waste, construction waste, and packaging paper, and then placed on transport vehicle 5. At this time, the reinforced diagonal beams A10 on both sides of the chassis 501 effectively prevent the bulk bags from rolling left and right as the transport vehicle 5 descends.

[0031] In one embodiment, the hoist 3 is fixed to the transport track 1 via a cross arm 11 and connected to the track cross beam 2 via a protective rope 12. The hoist 3 is positioned on a suitable platform at the top of the transport track 1 and secured using piles 13, pile columns 14, and the cross arm 11. Furthermore, the hoist 3 can be connected to the track cross beam 2 behind it via the protective rope 12, further enhancing the stability of the hoist 3.

[0032] In one embodiment, reinforced diagonal beams B16 are provided at the top and bottom of the transport track 1. The design of the reinforced diagonal beams B16 further improves the stability of the transport track 1. The reinforced diagonal beams B16 at the top of the transport track 1 can cooperate with the locking hook 6 to limit the initial position of the transport vehicle 5, ensuring that the transport vehicle 5 in the initial position does not slip, or to stop the transport vehicle 5 when it is reset.
