Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] Embodiment 1

[0032] See also Figure 1-2 8-9, the utility model provides a technical solution: a methanol range-extended electric mining truck integrated cooling pipeline device, comprising:

[0033] Two main clamping bodies 1, and one end of the two main clamping bodies 1 at corresponding positions is hinged to each other, a plurality of mounting grooves 2 are provided on the surface of the main clamping body 1, a locking ring 3 is rotatably provided at one end of the main clamping body 1, and a plurality of rubber positioning strips 4 are fixedly installed on the inner wall of the main clamping body 1, so that when the main clamping body 1 clamps the cooling pipeline, the friction between the cooling pipeline and the main clamping body 1 can be increased, a rotation groove is provided at one end of the main clamping body 1 corresponding to the position of the locking ring 3, and the rotation groove is a concave structure, and the cross section of the locking ring 3 is an I-shaped structure, so that when the two main clamping bodies 1 are hinged to each other and form a circular ring structure, the locking ring 3 will not be separated from the rotation groove, and the inner wall of the rotation groove is roughened to increase the resistance between the locking ring 3 and the rotation groove;

[0034] The clamping assembly is arranged on the surface of the main clamping body 1 and connected to the main clamping body 1 through the mounting groove 2. The clamping assembly is used to clamp the cooling pipeline in multiple directions. The clamping assembly includes a first auxiliary clamping body 51. One end of the first auxiliary clamping body 51 is hinged with a second auxiliary clamping body 52. ​​The first auxiliary clamping body 51 and the second auxiliary clamping body 52 are both semicircular ring structures. One end of the first auxiliary clamping body 51 away from the hinge position of the second auxiliary clamping body 52 is hinged with a rotating rod 53. The second auxiliary clamping body 52 rotates accordingly. A notch is provided at one end of the rod 53, and the rotating rod 53 is movably connected to the inner wall of the notch. A mounting plate 54 is fixedly installed at one end of the rotating rod 53 away from the first auxiliary clamping body 51, and a spring 55 is fixedly installed at one end of the mounting plate 54 corresponding to the rotating rod 53. A positioning block 56 is fixedly installed at one end of the spring 55 away from the mounting plate 54, and the positioning block 56 is tightly fitted with one end of the second auxiliary clamping body 52. ​​The surfaces of the positions where the second auxiliary clamping body 52 and the positioning block 56 are tightly fitted are both rough. The positioning block 56 is arranged so that the positioning block 56 is pressed against the second auxiliary clamping body 52 under the extrusion of the spring 55 and prevents the second auxiliary clamping body 52 from being hinged to each other with the first auxiliary clamping body 51. A first threaded rod 57 is fixedly installed in the middle of the surface of the first auxiliary clamping body 51. The surface of the first threaded rod 57 is provided with a first locking block 58 and a first stop block 59, and the first locking block 58 and the first locking block 58 are respectively movably connected to the inner wall of the installation groove 2. The first locking block 58 and the first stop block 59 are both rectangular structures so that the second auxiliary clamping body 52 and the first auxiliary clamping body 51 are hinged to each other. A locking block 58 and a first stopper 59 cannot rotate on the inner wall of the installation groove 2, and the first threaded rod 57 is rotatably connected to the middle part of the first stopper 59, and the first threaded rod 57 is threadedly connected to the middle part of the first locking block 58, so that when the first auxiliary clamping body 51 drives the first threaded rod 57 to rotate, the first threaded rod 57 will be threadedly connected with the first locking block 58 and adjust the distance between the first locking block 58 and the first stopper 59, so that the first locking block 58 and the first stopper 59 are pressed against the inner wall of the installation groove 2;

[0035] When the above structure is used, the main cooling pipeline or the core cooling pipeline is first placed between the two main clamping bodies 1, and then the two main clamping bodies 1 are combined so that the two main clamping bodies 1 clamp it, and then the locking ring 3 is rotated so that the two locking rings 3 are mutually misaligned at one end of the main clamping body 1, thereby preventing the two main clamping bodies 1 from being hinged;

[0036] Then, the first auxiliary clamping body 51 is rotated, and the first auxiliary clamping body 51 drives the first threaded rod 57 to rotate, so that the first threaded rod 57 is threadedly connected with the first locking block 58, and the first locking block 58 and the first stop block 59 are separated from each other, and the first locking block 58 and the first stop block 59 are pressed against each other on the inner wall of the installation groove 2, so as to fix the position of the first auxiliary clamping body 51. At the same time, the first auxiliary clamping body 51 can be rotated to a required angle as needed, so that the first auxiliary clamping body 51 and the second auxiliary clamping body 52 can clamp the cooling pipeline at various angles according to different needs, and then the cooling pipeline is placed between the first auxiliary clamping body 51 and the first auxiliary clamping body 52. The second auxiliary clamping body 52 is interlocked and the rotating rod 53 is rotated, and the positioning block 56 is driven to squeeze the spring 55 until the rotating rod 53 is rotated into the notch at one end of the second auxiliary clamping body 52. ​​At this time, the positioning block 56 is released. Since the contact position between the positioning block 56 and the second auxiliary clamping body 52 is roughly set, no relative movement occurs between the two. At the same time, under the squeezing action of the spring 55, the positioning block 56 will be pressed against the first auxiliary clamping body 51 to prevent the first auxiliary clamping body 51 and the second auxiliary clamping body 52 from rotating relative to each other, thereby fixing and clamping the cooling pipeline, and the clamping angle can be adjusted as needed, thereby achieving the purpose of facilitating the assembly of complex cooling pipelines.

[0039] When the above structure is in use, the elastic frame 61 is first moved from one end of the mounting groove 2 to the inner wall of the mounting groove 2. When adjusting the position, the elastic frame 61 needs to be pressed downward by the double pipe clamp 62 to deform the elastic frame 61 so that the end of the elastic frame 61 corresponding to the position of the double pipe clamp 62 is away from the inner wall of the mounting groove 2. At this time, the positions of the double pipe clamp 62 and the elastic frame 61 can be adjusted. After determining the position of the double pipe clamp 62, the double pipe clamp 62 is loosened so that the elastic frame 61 is tightly fitted to the inner wall of the mounting groove 2 under the action of elasticity to play a fixing role. Then, two parallel cooling pipelines are placed on the inner wall of the double pipe clamp 62, and then one end of the double pipe clamp 62 corresponding to the position of the ratchet 63 is pressed downward until the ratchet 63 and one end of the double pipe clamp 62 abut against each other, thereby realizing the assembly of two cooling pipelines that are tightly fitted and parallel to each other.

At the same time, during the fixing process, the angles of the two groups of main clamping bodies 1 can also be adjusted to adapt to the assembly of cooling pipelines at multiple angles, and a modular assembly method can be added to meet the needs of complex cooling pipelines.
