[0040] In the description of the present invention, if the terms first and second are used only for the purpose of distinguishing technical features, they should not be construed as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features or implicitly indicating the sequence of the indicated technical features.

[0041] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installation, connection, etc. should be understood in a broad sense, and those skilled in the art can reasonably determine the specific meanings of the above terms in the present invention in combination with the specific content of the technical solution.

[0042] The following refers to the attached Figure 1 to the attached Figure 6 to describe the spliced track rack according to the embodiment of the first aspect of the present invention.

[0043] Refer to Figures 1 to 3, the spliced track rack of this embodiment includes a frame body, a plurality of track rollers 200 and a plurality of movable wheel assemblies 300; the frame body is assembled by at least two semi-frame bodies 100 that are detachably connected in sequence; the plurality of track rollers 200 are respectively arranged at the bottoms of the two semi-frame bodies 100 located on both sides of the frame body, and the track rollers 200 are all located on the side away from the other semi-frame body 100 of the semi-frame body 100 where they are located; the plurality of movable wheel assemblies 300 are respectively arranged at the bottom of one side where each semi-frame body 100 is spliced with the other semi-frame body 100. The movable wheel assembly 300 includes a movable mounting member and a support roller 310. The support roller 310 is arranged on the movable mounting member, and the movable mounting member is movably connected to the semi-frame body 100. The support roller 310 can be driven by the movable mounting member to switch between a working position and a retracted position. The retracted position is higher than the working position, and when the movable wheel assembly 300 is in the working position, the support roller 310 can support the semi-frame body 100 where it is located, or can jointly support the semi-frame body 100 where it is located with the track roller 200.

[0044] Referring to Figure 1 , it can be understood that for the convenience of disassembling and assembling the track rack, the frame body should not be divided into too many semi-frame bodies 100. In this embodiment, specifically, the frame body is spliced by two semi-frame bodies 100, so as to improve the efficiency of disassembling and splicing the track rack; and specifically, the track rollers 200 are arranged on the side where the two semi-frame bodies 100 are away from each other, that is, the outer sides of the two semi-frame bodies 100, while the movable wheel assemblies 300 are arranged on the side where the two semi-frame bodies 100 are spliced. When the track rack needs to be repaired and transported, the connection between the two semi-frame bodies 100 can be released, so that the track rack is disassembled into two independent parts. At this time, support rollers 310 and track rollers 200 will be respectively arranged on both sides of the semi-frame body 100. Therefore, these two semi-frame bodies 100 will form independent trolleys with the support rollers 310 and the track rollers 200, that is, both of the two independent parts formed after the track rack is disassembled can form trolleys for rolling and pushing on the ground, thereby further reducing the difficulty of handling.

[0045] It should be understood that, according to the actual application, in some other embodiments, the frame may also be configured to be formed by splicing three half - frames 100 or more than three half - frames 100; and specifically, track rollers 200 may be provided on the outer sides of the bottoms of the half - frames 100 on both sides of the frame, while support rollers 310 may be provided on the inner sides of the bottoms of the half - frames 100 on both sides of the frame. At the same time, support rollers 310 are provided at the bottoms of both sides where the half - frame 100 in the middle position of the frame is connected to the other half - frames 100. Thus, when the track rack needs to be repaired and transported, the connection between the half - frames 100 can be released, so that the track rack is disassembled into three or more independent parts. Since support rollers 310 and track rollers 200 are respectively provided on both sides of the bottoms of the two half - frames 100 on both sides of the frame, these two half - frames 100 will form independent trolleys with the support rollers 310 and the track rollers 200. And since support rollers 310 are also provided on both sides of the half - frame 100 in the middle of the frame, the half - frame 100 in the middle of the frame will also form an independent trolley with the support rollers 310. Furthermore, after the track rack is disassembled into three or more parts, each part can also form a trolley for rolling and pushing on the ground.

[0046] It can be understood that, and because the position of the support roller 310 can be switched between the working position and the retracted position, the support roller 310 can be switched to the working position for transportation when needed, and when the track rack is on the track, the support roller 310 can be retracted to avoid damage to the support roller 310 during the operation of the track operation equipment.

[0047] Refer to Figure 2 , it can be understood that, in this embodiment, the track roller 200 includes a wheel body and a flange. The flange is provided on one side of the wheel body. The wheel body is used to contact the upper surface of the track to support the frame on the track; it should be understood that when the support roller 310 is in the working position, the bottom of the wheel surface of the support roller 310 will be flush or substantially flush with the bottom of the flange. Thus, when the trolley formed by the half - frame 100, the support roller 310 and the track roller 200 is pushed on the ground, the ground will be supported by the flange of the track roller 200 and the wheel surface of the support roller 310.

[0048] It should be understood that, according to the actual situation, in some other embodiments, the track roller 200 may not be provided with a flange. At this time, when the support roller 310 is in the working position, the bottom of the wheel surface of the support roller 310 will be flush or substantially flush with the bottom of the wheel body of the track roller 200. Thus, when the trolley formed by the half - frame 100, the support roller 310 and the track roller 200 is pushed on the ground, the ground will be supported by the wheel surface of the wheel body of the track roller 200 and the wheel surface of the support roller 310.

[0049] Referring to Figure 2 and Figure 3 ,it can be understood that in this embodiment, the movable mounting member is rotatably connected to the bottom of the semi-frame 100. By rotating the movable mounting member, the support roller 310 can be switched between the working position and the retracted position, thereby facilitating the switching of the position of the support roller 310. And specifically, the spliced rail rack of this embodiment further includes a 90-degree self-locking folding hinge 400. The movable mounting member is a roller mounting seat 320, and the roller mounting seat 320 is rotatably connected to the semi-frame 100 through the 90-degree self-locking folding hinge 400. The 90-degree self-locking folding hinge 400 allows the roller mounting seat 320 to rotate within a 90-degree angle range, and can be self-locked at two extreme positions spaced 90 degrees apart. That is, without manual unlocking, the support roller 310 can be maintained in the working position and the retracted position. It can be understood that since the 90-degree self-locking folding hinge 400 is an existing component, the specific structure of the 90-degree self-locking folding hinge 400 will not be described in detail here.

[0050] Referring to Figure 1 ,in this embodiment, specifically, two track rollers 200 are provided on the outer sides of the bottoms of the two semi-frames 100, and two movable wheel assemblies 300 are provided on the inner sides of the bottoms of the two semi-frames 100, that is, on the side where the two semi-frames 100 are spliced together. And specifically, each support roller 310 is independently mounted on a roller mounting seat 320, and each roller mounting seat 320 is rotatably connected to the bottom of the semi-frame 100 through a 90-degree self-locking folding hinge 400, so that the position of each support roller 310 can be independently controlled and switched.

[0051] It should be understood that in addition to the way of rotatably connecting the above-mentioned movable mounting member to the bottom of the semi-frame 100, according to the actual situation, in some other embodiments, the movable mounting member can also be set to be slidably arranged in a liftable manner at the bottom of the semi-frame 100; for example, the movable mounting member can be set to be slidable up and down on the lift of the semi-frame 100, and the support roller 310 is arranged at the bottom of the lift, so that the position of the support roller 310 can be switched by means of lifting and moving.

[0052] It should be understood that, in addition to the option of separately and independently controlling the switching positions of each support roller 310 as described above, according to the actual situation, in some other embodiments, multiple support rollers 310 on the same side of each half-frame 100 can also be uniformly switched, thereby improving the efficiency of the position switching of the support rollers 310. For example, the movable mounting member can be set as a flipping bracket, on which multiple support rollers 310 are mounted and rotatably connected to the bottom of the half-frame 100, so as to drive multiple support rollers 310 to switch between the working position and the retracted position by rotating the flipping bracket.

[0053] Referring to Figure 1 , Figure 4 and Figure 5 , it can be understood that, in this embodiment, to achieve the quick connection and disassembly between the half-frames 100 and improve the installation and disassembly efficiency, specifically, two adjacent half-frames 100 are detachably connected by a quick connection assembly 500. And, in this embodiment, specifically, the quick connection assembly 500 includes a first connecting member 510, a second connecting member 520 and a connecting rod 530. The first connecting member 510 and the second connecting member 520 are respectively arranged on two adjacent half-frames 100. A first connection hole 517 is provided on the first connecting member 510, and a second connection hole 521 corresponding to the position of the first connection hole 517 is provided on the second connecting member 520. The connecting rod 530 passes through the first connection hole 517 and the second connection hole 521 to connect the first connecting member 510 and the second connecting member 520. Thus, when it is necessary to carry the track rack, by pulling out the connecting rod 530 from either the first connection hole 517 or the second connection hole 521, the connection between two adjacent half-frames 100 can be released. And when reconnecting two adjacent half-frames 100, just insert the connecting rod 530 back into the first connection hole 517 and the second connection hole 521.

[0054] Referring to Figure 5 , it can be understood that, in this embodiment, the first connecting member 510 includes a first splicing portion 511, and a convex block 512 is provided on the first splicing portion 511. The second connecting member 520 includes a second splicing portion 522, and a splicing groove 523 that fits with the convex block 512 is provided on the second splicing portion 522. When the first connecting member 510 and the second connecting member 520 are connected to each other, the convex block 512 will be embedded into the splicing groove 523, so that the first connecting member 510 and the second connecting member 520 can be positioned relative to each other, thereby avoiding relative shaking between two adjacent half-frames 100 due to a gap between the first connecting member 510 and the second connecting member 520 after connection, and thus improving the operation accuracy of the track operation equipment during operation.

[0055] It can be understood that the first connecting hole 517 passes through the convex block 512, and the second connecting hole 521 is provided at the bottom or the wall of the splicing groove 523. Thus, after the convex block 512 and the splicing groove 523 are engaged, the first connecting hole 517 and the second connecting hole 521 will be automatically aligned, which facilitates the connecting rod 530 to pass through the first connecting hole 517 and the second connecting hole 521.

[0056] Referring to Figure 5 , it can be understood that in this embodiment, specifically, a first guiding inclined surface 524 is provided at the opening of the splicing groove 523 facing the first connecting member 510, and the convex block 512 is provided with a second guiding inclined surface 513 that cooperates with the first guiding inclined surface 524. With the cooperation of the first guiding inclined surface 524 and the second guiding inclined surface 513, the convex block 512 can enter the splicing groove 523 more easily. Moreover, with the wedge-shaped cooperation between the first guiding inclined surface 524 and the second guiding inclined surface 513, it can be ensured that after splicing, the inner walls of the convex block 512 and the splicing groove 523 can be closely fitted, further avoiding the occurrence of gaps between the inner walls of the convex block 512 and the splicing groove 523 due to reasons such as machining precision errors.

[0057] Referring to Figure 5 , it can be understood that in this embodiment, a guiding cam 514 is further provided on the first connecting member 510, and a guiding groove 525 for cooperating with the guiding cam 514 is provided on the second connecting member 520. Thus, when connecting the first connecting member 510 and the second connecting member 520, with the cooperation of the guiding cam 514 and the guiding groove 525, the convex block 512 can enter the splicing groove 523 quickly and accurately. And specifically, a horn-shaped guiding inlet is provided at the entrance of the guiding groove 525, the width of the insertion end of the guiding inlet is greater than the diameter of the guiding cam 514, and the width of the rear end of the guiding inlet matches the guiding cam 514. Thus, when connecting two adjacent half frames 100, only by making the guiding cam 514 roughly align with the guiding inlet, and then pushing the two half frames 100 closer to each other, the guiding cam 514 can automatically enter the rear end of the guiding groove 525. At the same time, the convex block 512 will also automatically and accurately be embedded into the splicing groove 523. Therefore, when splicing the two half frames 100, it is not necessary to align the two half frames 100 with high-precision requirements, thereby reducing the connection difficulty.

[0058] Referring to Figure 5It can be understood that, in this embodiment, the first connecting member 510 also includes a first fixing portion 515, the first fixing portion 515 is arranged on one side of the first splicing portion 511, and the first fixing portion 515 is provided with a first fixing hole 516. The first connecting member 510 is fixed to one half of the frame 100 by a fastener passing through the first fixing hole 516, and the second connecting member 520 is provided with a second fixing portion 526. The second fixing portion 526 is arranged on the side of the second splicing portion 522 away from the first fixing portion 515, and the second fixing portion 526 is provided with a second fixing hole 527. The second connecting member 520 is fixed to the other half of the frame 100 by a fastener passing through the second fixing hole 527. By respectively arranging the above-mentioned first fixing portion 515 and the second fixing portion 526 on the first connecting member 510 and the second connecting member 510, and respectively arranging the first fixing hole 516 and the second fixing hole 527 on the first fixing portion 515 and the second fixing portion 526, the first connecting member 510 and the second connecting member 520 can be conveniently fixed to two adjacent half-frames 100; and after long-term use, if the first connecting member 510 and the second connecting member 520 are damaged, the fasteners passed through the first fixing hole 516 and the second fixing hole 527 can be removed, and then the first connecting member 510 and the second connecting member 520 can be replaced respectively.

[0059] Reference Figure 1 and Figure 5 It can be understood that, in the present embodiment, specifically, the first fixing portion 515 and the protrusion 512 are respectively located at two adjacent side surfaces of the first splicing portion 511, while the second fixing portion 526 and the insertion end of the splicing groove 523 are respectively arranged at two adjacent side surfaces of the second splicing portion 522, and the first fixing portion 515 and the second fixing portion 526 are opposite to each other, wherein the first connecting hole 517 passes through the first splicing portion 511 and the protrusion 512, the second connecting hole 521 is arranged at the bottom of the splicing groove 523 and passes through the second splicing portion 522, and the guide groove 525 is arranged on one side of the second splicing portion 522 connected to the second fixing portion 526, and at the same time, the connecting rod 530 is arranged in the first connecting hole 517 and the second connecting hole 521 parallel to the extension direction of the guide groove 525.
