Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of crawler transport vehicles, in particular to a crawler transport vehicle which can be unfolded to transport large objects. Background Art
[0002] Construction machinery transport trucks are common large-scale heavy-duty trucks in life. They are mainly used to transport materials and equipment required for construction projects. They have strong load-bearing capacity and are currently widely used in factories, construction sites and other large-scale production or engineering sites. They play an important role in the process of economic development. However, with the different environments of project construction, transportation often encounters some complex areas such as steep terrain, large slopes, and mud. Ordinary transport trucks are wheeled transport trucks, which cannot pass when encountering such road conditions. The transportation of construction materials can only rely on manpower, which is time-consuming, labor-intensive, and inefficient. Especially in some mountainous and remote areas, in the construction of tunnels and bridges, the advantages of transport trucks cannot be fully utilized, highlighting its shortcomings, which is also one of the main problems that plague engineering staff. In this case, crawler transport trucks came into being;
[0003] When existing tracked transporters are loading cargo, the size of the cargo is limited by the size of the transporter. When loading larger cargo, the large cargo is not placed stably, which affects transportation. Transporting larger cargo requires custom-made tracked transporters with large loading capacity, which increases costs. To address the above problems, the present application designs a tracked transporter that can be unfolded to transport large objects. Utility Model Content

[0007] To achieve the above object, the present utility model provides the following technical solutions: A crawler transporter capable of expanding and transporting large objects, comprising a base and a crawler traveling device. The base is fixed at the top of the crawler traveling device. A support structure that can be expanded and loaded is provided on the base. The support structure includes a storage groove. The storage groove is opened on the side wall of the base. Two storage grooves are symmetrically opened on the front and rear side walls of the base. A support rod is rotatably connected to the outer end of the storage groove. The middle of the support rod is cylindrical.

Detailed Description of the Preferred Embodiments
[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0022] Please refer to Figures 1-4, a crawler transporter capable of unfolding and transporting large objects, comprising a base 1 and a crawler traveling device 2. The base 1 is fixed at the top of the crawler traveling device 2. A support structure that can be unfolded and loaded is provided on the base 1. The support structure includes a storage groove 3. The storage groove 3 is opened on the side wall of the base 1. Two storage grooves 3 are symmetrically opened on the front and rear side walls of the base 1. A support rod 4 is rotatably connected to the outer end of the storage groove 3. The middle of the support rod 4 is cylindrical. A support angle block 5 is rotatably connected to the middle position of the support rod 4. A short sliding groove 6 is opened at one end of the support rod 4 near its rotation axis. A short rod 7 is slidably connected in the short sliding groove 6. A long sliding groove 8 is opened at the other end of the support rod 4. A long rod 9 is slidably connected in the long sliding groove 8. A rotating shaft 10 is fixed at the middle position inside the support rod 4. A threaded rod 11 is fixed on the rotating shaft 10. The two ends of the threaded rod 11 are respectively provided with a long thread 12 and a short thread 13. The long thread 12 end of the threaded rod 11 is located in the long sliding groove 8 and is threadedly connected to the long rod 9. The short thread 13 end of the threaded rod 11 is located in the short sliding groove 6 and is threadedly connected to the short rod 7. At the front and rear ends of the top of the base 1, a first baffle 14 is rotatably connected. A second baffle 15 is rotatably connected to the top of the first baffle 14. Two support protrusions 16 are symmetrically fixed on the non-contact sides of the first baffle 14 and the second baffle 15. A back plate 17 is fixed at one end of the top of the base 1 where the first baffle 14 is located.
[0023] When this crawler transporter is in use, when loading large goods, first rotate the support rod 4 to make the support rod 4 rotate out of the storage groove 3. While the support rod 4 rotates out, under the action of gravity, the support angle block 5 rotates with the support rod 4. The support angle block 5 rotates from a horizontal state to a vertical state. At the same time, the support angle block 5 contacts the side wall of the base 1 and plays a supporting role for the support rod 4 under the action of force. Wait until the support rod 4 rotates to a right angle with the base 1 and stop rotating. Then pull out the long rod 9 in the long sliding groove 8. Since the long rod 9 is threadedly connected to the threaded rod 11, and at the same time, the threaded rod 11 cannot move in position under the action of the rotating shaft 10 but can rotate. Therefore, when pulling the long rod 9, the threaded rod 11 rotates, so that the short thread 13 rotates. The short rod 7 is threadedly connected to the short thread 13, thereby driving the short rod 7 to move outward along the short sliding groove 6. The long thread 12 and the short thread 13 are set so that when the long rod 9 extends to the longest, the short rod 7 also extends to the longest. The short rod 7 extends into the storage groove 3 and contacts its upper and lower inner walls. At the same time, the long rod 9 extends outward. Rotate the second baffle 15 to make it in the same plane as the first baffle 14. Then rotate the first baffle 14 so that the first baffle 14 and the second baffle 15 are in a horizontal state. At this time, the support protrusion 16 contacts the support rod 4 to support the first baffle 14 and the second baffle 15, realizing the expansion of the loading platform for loading large goods.
[0024] It was found in actual use that in order to facilitate the fixing of the first baffle 14 and the second baffle 15 and prevent them from rotating, in this embodiment, two clamping blocks 18 are symmetrically fixed on one side of the back plate 17 close to the first baffle 14 and the second baffle 15, and the front and rear ends of the back plate 17 are rotatably connected with clamping blocks 19, and the clamping blocks 19 are in contact with the first baffle 14.
[0025] It is found in actual use that the support rod 4 may rotate to the innermost part of the storage slot 3 and is not easy to take out. In order to avoid the above problem, in this embodiment, a limit stopper 20 is fixed in the storage slot 3.
[0026] It is found in actual use that after the goods are loaded, they may slip, making it difficult to transport the goods. In order to solve the above problem, in this embodiment, the top of the base 1 is provided with anti-slip grooves, and the sides where the first baffle plate 14 and the second baffle plate 15 contact each other are provided with anti-slip grooves.
[0027] In actual use, it is found that when pulling the long rod 9, there is no fulcrum, slipping is likely to occur, and it is inconvenient to pull. In order to solve the above problem, in this embodiment, hand-gripping grooves 21 are opened on the side walls around the outer end of the long rod 9.
[0028] In actual use, it is found that the support rod 4 is located in the storage groove 3 and is not easy to rotate out. In order to solve the above problem, in this embodiment, a handle 22 is fixed on the side wall located on the outside of the support rod 4.
