[0043] In an embodiment of the present application, both the bridge frame assembly and the tank car assembly are movably arranged along the length direction of the support assembly. A buffer space is formed between the load-carrying part of the bridge frame assembly and the support part of the support assembly. The top of the tank car assembly forms a receiving tank. During the pipeline transfer process, the tank car assembly is connected to the end car of the mobile transformer train. When pulling the mobile transformer, the tank car assembly advances together with the mobile transformer train. The bridge frame assembly is connected to the upper bridge frame of the horseshoe. When pushing the machine head, the bridge frame assembly and the horseshoe are simultaneously pushed forward. Part of the pipeline is located in the receiving tank, part of the pipeline is located on the support part, and part of the pipeline bypasses through the buffer space to the load-carrying part. In the above solution, the pipelines along the gate road are located on the tank car assembly and the bridge frame assembly, so that the pipelines along the gate road are grounded, replacing the use of a single-track crane to suspend the pipelines in the air, so as to avoid the safety hazards brought by working at heights.

[0044] In an exemplary embodiment of the present application, the support assembly 1 includes: a support frame 11, a first track 13 and a second track 14. The top surface of the support frame 11 forms a support part 12. There are two groups of the first tracks 13. The two groups of first tracks 13 are arranged on the support part 12 at intervals along the width direction of the support frame 11, and both groups of first tracks 13 extend along the length direction of the support frame 11.

[0045] Further, the bridge frame assembly 2 includes: a gantry 21 and a connecting beam 22. There are multiple gantries 21. The multiple gantries 21 are arranged at intervals along the length direction of the support frame 11. Among them, a cross beam 211 is provided at the first end of the gantry 21 away from the support frame 11, and a pulley 26 is provided at the second end of the gantry 21 close to the support frame 11. The gantry 21 is slidably connected to the first track 13 through the pulley 26. The connecting beam 22 is arranged between two adjacent gantries 21. Each gantry 21 is connected to the connecting beam 22 through the cross beam 211. The top surface of the connecting beam 22 forms a load-carrying part 23.

[0046] Specifically, as Figure 1 、 Figure 3As shown, the gantry 21 includes a cross beam 211 and longitudinal beams 212. The cross beam 211 is connected between two longitudinally spaced longitudinal beams. There are two connecting beams 22, and the two connecting beams 22 are spaced along the width direction of the gantry 21, that is, each connecting beam 22 is connected between multiple longitudinal beams 212 distributed along the length direction of the bridge component. The connecting beam 22 can not only connect multiple gantries 21 to form a whole, but also play a role in supporting pipelines. On both the left and right sides of the second end of the gantry 21, there are pulleys 26. The pulleys 26 are rotatably connected to the gantry 21. The first track 13 is a channel steel, and the pulleys 26 extend into the channel steel and slide within the channel steel under the action of an external force.

[0047] Furthermore, the bridge component 2 further includes: a strengthening beam 24. The strengthening beam 24 is connected between two adjacent gantries 21, and the strengthening beam 24 and the connecting beam 22 are spaced along the height direction of the gantry 21.

[0048] Specifically, as Figure 1 、 Figure 3 shown, the strengthening beam 24 is located in the middle of one side of the gantry 21 to connect two adjacent gantries 21. The setting of the strengthening beam 24 further improves the strength of the bridge component 2.

[0049] Furthermore, the bridge component 2 further includes: a guide roller 25. The guide roller 25 is rotatably connected to the gantry 21 at the head of the bridge component 2. The axis of the guide roller 25 extends along the width direction of the gantry 21. The pipeline located in the buffer space 4 is wound around the carrying part 23 after passing through the guide roller 25.

[0050] Specifically, as Figure 4 shown, there is a bracket on the outside of the gantry 21 at the head of the bridge component 2, and the guide roller 25 is rotatably connected to the bracket. The pipeline is in rotational contact with the guide roller 25, reducing the friction between the pipeline and the guide roller 25 to avoid damage to the pipeline due to friction.

[0051] In another exemplary embodiment of the present application, the tank car assembly 3 includes: tank cars 31. There are multiple tank cars 31, and the multiple tank cars 31 are spaced along the length direction of the support frame 11. Adjacent tank cars 31 are detachably connected. Among them, a receiving groove is formed at the top of the tank car 31. The detachable connection between adjacent tank cars 31 allows the number of tank cars 31 to be adjusted according to the actual working conditions to change the length of the tank car assembly.

[0052] Furthermore, as Figure 6 、 Figure 7 、 Figure 8As shown in the figure, two adjacent tank trucks 31 are connected by a connecting block 32. A countersunk hole 33 is provided on the side wall of the tank truck 31, and the countersunk end of the countersunk hole 33 is located on the inner side wall of the tank truck 31. The connecting block 32 is connected to the countersunk hole 33 by a bolt, and the head of the bolt is located in the countersunk hole 33. The head of the bolt is located in the countersunk hole 33, that is, the head of the bolt does not extend into the receiving groove of the tank truck, so as to prevent the bolt from hooking the pipeline inside the tank truck.

[0053] Further, there are multiple countersunk holes 33, and the multiple countersunk holes 33 are arranged at intervals along the height direction of the tank truck 31. That is, two adjacent tank trucks 31 are connected by multiple connecting blocks 32, and the multiple connecting blocks 32 are arranged at intervals along the height direction of the tank truck, so as to improve the connection strength of the tank truck assembly 3.

[0054] Further, as Figure 5 shown in the figure, one end of the tank truck 31 close to the support frame 11 is provided with a slider 34. The slider 34 extends along the length direction of the tank truck 31, and the slider 34 has a chute, and the chute runs through along the length direction of the slider 34; the second track 14 is an I-beam, and the tank truck 31 is slidably connected to the second track 14 through the slider 34.

[0055] Further, as Figure 9 、 Figure 10 shown in the figure, each group of second tracks 14 includes multiple second tracks 14, and the multiple second tracks 14 are arranged butt-jointed along the length direction of the support frame 11; a guide block 35 is provided in the chute of the slider 34, and the guide block 35 is arranged in the chute along the length direction of the slider 34. The chute is slidably connected to the second track 14 through the guide block 35. Among them, the guide block 35 has two inclined guide surfaces 351, and the two guide surfaces 351 are arranged opposite to each other along the length direction of the guide block 35.

[0056] It should be noted that each group of second tracks 14 is composed of multiple second tracks 14 spliced together, and there may be a height difference between two adjacent second tracks 14. The tank truck 31 is slidably connected to the second track 14 through the guide block 35. The guide surface 351 of the guide block 35 first passes through the splicing part of the second track 14, and the height difference at the splicing part is offset by the guide surface 351 to prevent the tank truck 31 from shaking up and down.

[0057] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0058] During the pipeline transfer process, the tank car assembly is connected to the end car of the mobile transformer train. When pulling the mobile transformer, the tank car assembly moves forward together with the mobile transformer train. The bridge assembly is connected to the upper bridge of the horseshoe. When pushing the shearer head, the bridge assembly and the horseshoe advance forward simultaneously. Part of the pipeline is located in the receiving tank, part is located on the support part, and part of the pipeline bypasses through the buffer space and winds around to the carrying part, causing the pipelines along the gate roadway to land, replacing the use of single-track cranes to suspend the pipelines, so as to avoid the safety hazards brought by working at heights.
