Description

Technical Field

[0001] This utility model relates to the field of transportation vehicle technology, specifically to an underground trackless heavy-duty transport vehicle. Background Technology

[0002] As the demand for drainage capacity in mine shafts continues to increase, the requirements for the head and drainage volume of drainage equipment are also rising. Consequently, drainage equipment must become increasingly larger to meet these demands. However, the heavy weight of large drainage equipment makes transportation a challenge during construction. This is especially true given current construction standards that prioritize the construction of drainage equipment, requiring drainage chambers to be built first. Therefore, the installation of drainage equipment is often carried out concurrently with other projects. During this process, the roadway surface is often uneven. Traditional transport vehicles require the use of existing transport tracks. If these tracks are not yet in place, temporary tracks need to be laid for installation. These temporary tracks also need to be dismantled after transportation. The laying and use of these temporary tracks necessitates halting other construction work, impacting the construction schedule and incurring additional costs for temporary track laying. Therefore, it is difficult to safely and efficiently transport heavy equipment such as large drainage systems to their designated locations. Utility Model Content

[0030] This embodiment discloses an underground trackless heavy-duty transport vehicle. Please refer to [link / reference]. Figure 1 and Figure 2 The trackless heavy-duty transport vehicle in this embodiment is an improvement on the traditional rail flatcar, and includes a rail flatcar, support member 4, enlarged wheels 5, and a second frame.

[0031] The rail flatcar is a standard piece of equipment commonly used in mining, mainly consisting of a first frame 1 and its bottom axles 2 and rail wheels 3. As shown in the figure, two axles 2 are located at the front and rear of the lower part of the first frame 1, and rail wheels 3 are mounted on both ends of the axles 2 via bearings. Traditional rail flatcars need to run on specific tracks during use. The trackless heavy-duty transport vehicle in this embodiment improves upon the traditional rail flatcar, allowing it to run without using tracks.

[0032] Specifically, several support members 4 are uniformly fixed around the outer periphery of the rail wheel 3, and an enlarged wheel 5 is fixedly installed around the outer periphery of the support members 4. The enlarged wheel 5 has a cylindrical structure, and its diameter and width both exceed those of the original rail wheel 3. Figure 2 As shown, the width of the enlarged wheel 5 along the axle 2 direction is more than twice the width of the rail wheel 3, which increases the contact area with the ground. It is suitable for traveling in trackless underground roadways and can prevent the wheels from being deformed or pressed into the roadway floor when transporting heavy equipment, thus preventing normal travel.

[0033] The second frame is fixedly installed above the first frame 1, including a support beam 6 and a top support plate 7. The support beam 6 is fixedly connected to the first frame 1, which not only transmits the load but also raises the middle part of the support plate 7 to prevent the extended wheels 5 from interfering with the second frame and becoming unusable. The support plate 7 can expand the usable area of ​​the transport vehicle.

[0034] It should be noted that the positions of the rail wheels 3 and the enlarged wheels 5 are offset from the positions of the crossbeams on the first frame 1 and the second frame in the length direction of the transport vehicle, to ensure that each wheel can operate normally during use.

[0035] In this embodiment, the support member 4 is a steel plate with a thickness of more than 20mm, and its two ends are fixedly connected to the rail wheel 3 and the enlarged wheel 5 respectively, which can firmly assemble the enlarged wheel 5 and the rail wheel 3 together.

[0036] Furthermore, since the rail wheel 3 and the enlarged wheel 5 have different widths, in order to increase the connection strength between them, in this embodiment, the support member 4 has a trapezoidal structure, with its shorter top edge welded to the rail wheel 3 and its longer bottom edge welded to the inner wall of the enlarged wheel 5, ensuring that the enlarged wheel 5 can be firmly connected to the rail wheel 3 during use.

[0037] More specifically, in this embodiment, the enlarged wheel 5 is a steel pipe with a diameter of 640mm, a thickness of 12mm, and a length of 450mm. As an additional wheel to the original rail wheel 3, it can increase the contact area with the ground, preventing the wheel from being deformed or pressed into the tunnel floor when transporting heavy equipment, thus preventing normal operation.

[0038] Furthermore, in this embodiment, several raised patterns or protrusions are provided on the outer periphery of the enlarged wheel 5, which can improve its friction with the ground and make the underground trackless heavy-duty transport vehicle more stable when it is in motion.

[0039] In this embodiment, the supporting beam 6 of the second frame is an I-beam, and the supporting plate 7 is a steel plate with a thickness of 20mm or more. The two are welded together to form the second frame, which serves as a platform to support the equipment to be transported. The I-beam not only transmits the load but also raises the middle part of the second frame to prevent the extended wheels 5 from interfering with the second frame and becoming unusable, and also expands the usable area of ​​the transport vehicle. The upper surface of the second frame is paved with thick steel plates to prevent heavy equipment from squeezing and deforming the transport vehicle, and the spacing between the lower I-beams can be appropriately increased to control the overall weight of the transport vehicle.

[0040] Furthermore, in this embodiment, a plurality of hooks 8 are fixedly provided on the outer side of the second frame, with the front ends of the hooks 8 bent downwards. When transporting large and heavy equipment, cables can be used to connect to these hooks 8, making the large and heavy equipment and the transport vehicle a single unit, preventing it from tipping over. In this embodiment, the hooks 8 are evenly fixed on both sides of the second frame, resulting in more uniform fixation of the large and heavy equipment during use.

[0041] In addition, in this embodiment, the hook 8 is a bent component made of round steel with a diameter of 18mm, which is a commonly used material on construction sites and can be processed and manufactured at a low cost.

[0042] Compared with existing technologies, this trackless heavy-duty transport vehicle for underground mining has the following advantages:

[0043] 1. Compared to using large mechanical equipment to lift heavy equipment, which cannot control the swing of the heavy equipment and is prone to damage to the equipment to be installed, this trackless underground heavy equipment transport vehicle can transport heavy equipment smoothly.

[0044] 2. With the help of widened wheels, this trackless heavy equipment transport vehicle can travel smoothly on trackless roadways, especially on uneven surfaces, avoiding the need for track construction required by traditional rail flatcars, and ensuring that large and heavy equipment can be transported safely and efficiently underground.

[0045] 3. The trackless heavy equipment transport vehicle for underground mining has a simple structure, is easy to manufacture using materials commonly used on the construction site, is safe and fast, and can transport large and heavy equipment to the designated installation and construction area quickly and efficiently without affecting other construction projects.

[0046] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
