[0027] To describe in detail the technical content, structural features, achieved objectives and effects of the present application, the technical solutions in the embodiments of the present application will be described below with reference to the accompanying drawings in the embodiments of the present application.

[0028] In the present application, spatial relative terms such as "under", "below", "beneath", "lower", "above", "upper", "on", "higher", "side" (for example, as in "side wall"), etc. are used to describe the relationship between one element and another (other) element as shown in the accompanying drawings. The spatial relative terms are intended to include different orientations of the device in use, operation and / or manufacture in addition to the orientation depicted in the accompanying drawings. For example, if the device in the accompanying drawings is flipped, the element described as "under" or "beneath" another element or feature will subsequently be positioned "above" the said other element or feature. Therefore, the exemplary term "under" can include both the upper and lower orientations. In addition, the device can be positioned otherwise (for example, rotated 90 degrees or at other orientations), and accordingly, the spatial relative descriptive terms used herein are interpreted.

[0029] The present utility model provides a wheel-rail mechanism for heavy-duty machinery to improve the safety when the heavy-duty machinery moves. As shown in the figure, the wheel-rail mechanism includes a gear train assembly 10 (see Figure 1 ) that can be installed at the bottom of the corresponding heavy-duty machinery, and a rail system assembly 20 (see Figure 4 ) for supporting the gear train assembly 10.

[0030] Refer to Figures 1 - 3, the gear train assembly 10 provided in this embodiment includes a wheel seat 1, a roller 2 rotatably mounted in the wheel seat 1, and a bracket 3. Among them, the roller 2 includes a roller shaft 21 fixedly installed in the wheel seat 1, a rolling bearing 22 sleeved on the roller shaft 21, and an outer ring wheel body 23 sleeved outside the rolling bearing 22. The outer ring wheel body 23 is configured such that a part of its outer surface is recessed inward along the radial direction (i.e., the radius direction of the roller shaft 21) to form an annular groove 24, and the annular groove 24 fits the top of the heavy-duty track 5 (see below).

[0031] Furthermore, the gear train assembly 10 is also configured with a spacer ring (not marked in the figure) filled between the inner wall of the wheel seat 1 and the rolling bearing 22 to prevent the rolling bearing 22 and the outer ring wheel body 23 from rubbing against the inner wall of the wheel seat 1.

[0032] First grooves 11 and 12 are formed on the wheel seat 1 respectively adapted to accommodate both ends of the roller shaft 21. Both the first and second grooves are formed by the inner surface of the wheel seat 1 recessing outward along the axial direction (i.e., the axis direction of the roller shaft 21). Among them, the first groove 11 has a bottom opening (not shown in the figure) for the staff to disassemble and assemble the roller shaft 21 (i.e., disassemble and assemble the roller 2) from the wheel seat 1.

[0033] Furthermore, a step structure 25 is formed at one end of the roller shaft 21 adapted to the first groove 11. The wheel seat 1 also includes a pressing plate 11 detachably installed at the bottom opening. The pressing plate 11 is adapted to limit the above step structure 25 from below to fix the roller shaft 21 inside the wheel seat 1.

[0034] The bracket 3 is fixedly installed (by means such as welding, integral molding or bolt connection) on the top of the wheel seat 1. It has a number of bolt holes 31 through which fastening bolts can pass, for the staff to fix the gear train assembly 10 to the bottom of the corresponding heavy-duty machinery.

[0035] Furthermore, the wheel seat 1 is also configured with a pair of side plates 12. Each side plate 12 is provided with a waist-shaped hole 13 through which a positioning bolt can pass to further improve the firmness of the gear train assembly 10 fixed to the corresponding heavy-duty machinery.

[0036] Refer to Figures 4 - 6 , which shows the track system assembly 20 provided in this embodiment. It includes a longitudinally extending backing plate 4, a heavy-duty track 5 also longitudinally extending and fixedly installed on the backing plate 4, and a number of mechanical limit blocks 6 installed on the heavy-duty track 5. The backing plate 4 is provided with a number of bolt holes 41 through which anchor bolts can pass to fix the backing plate 4 to the ground or the base.

[0037] The heavy-duty track 5 provided in this embodiment is an I-shaped track, which includes a narrow and thick rail head 51 at the top, a rail web 52 in the middle with both sides arcuately recessed inward, and a wide and thick rail base 53 at the bottom. The design of the I-shaped track can effectively resist bending moment and pressure, ensuring the smooth and safe travel of heavy-duty machinery. Among them, the rail head 51 is configured to be suitable for contacting the roller 2 and adapting to the annular groove 24 of the roller 2; the rail web 52 is used to connect the rail head 51 and the rail base 53; the rail base 53 provides sufficient stability and supporting capacity.

[0038] A number of adjustment blocks 54 are also arranged on the heavy-duty track 5. The adjustment blocks 54 are used to lock the heavy-duty track to prevent it from moving left and right, and can be used during the track laying, maintenance or fine adjustment process to compensate for the wear or deformation of the track material. During installation, the adjustment blocks 54 are locked and fixed on the backing plate 4 by bolts. There is a certain gap between the adjustment blocks 54 and the backing plate 4. Slowly tighten the bolts to press the adjustment blocks and the heavy-duty track onto the backing plate 4.

[0039] The mechanical limit block 6 includes a top plate 61 suitable for contacting the top of the rail head 51, a pair of side plates 62 suitable for contacting the two side edges of the rail head 51, and a pair of inclined plates 63 respectively fixedly connected to the lower sides of the pair of side plates 62 and inclined inward. When the mechanical limit block 6 is installed on the heavy-duty track 5, the pair of inclined plates 63 are located at the rail web 52. Thus, the mechanical limit block 6 can be movably installed on the heavy-duty track 5 in the longitudinal direction and will not easily break away from the heavy-duty track 5. Among them, a number of threaded holes are also provided on the pair of side plates 62 of the mechanical limit block 6 to lock the mechanical limit block 6 to the heavy-duty track 5 through locking bolts.

[0040] When the wheel-rail mechanism provided by the present utility model is actually used, at least four sets of wheel system components 10 can be arranged at the bottom of the heavy-duty machinery, and at least two sets of rail system components 20 can be installed on the ground. The heavy-duty machinery can be movably supported on at least two heavy-duty tracks 5 via at least four rollers 2. Among them, the annular grooves 24 of the respective rollers 2 cooperate with the top of the heavy-duty track 5 to prevent the heavy-duty machinery from being displaced in the lateral direction and breaking away from the heavy-duty track 5; at least one mechanical limit block 6 can limit the heavy-duty machinery in the longitudinal direction to prevent the heavy-duty machinery from being displaced in the longitudinal direction or running out of the preset travel range due to huge inertia during movement.

[0041] The above embodiments are only for illustrating the technical concept and features of the present application, and the purpose is to enable those who are familiar with this technology to understand the content of the present application and implement it accordingly, and cannot be used to limit the protection scope of the present application. All equivalent changes or modifications made according to the spirit of the present application should be covered within the protection scope of the present application.
