[0032] It should be noted that the features in the embodiments of the utility model can be combined with each other without conflict.

[0033] The segmented walking frame device 10 provided by the utility model and the overall structure, working principle and technical effects of the tracked mobile equipment will be described in detail below through embodiments and in combination with the drawings.

[0034] Please refer to Figures 1 to 4 The utility model provides a segmented walking frame device 10, applied to tracked mobile equipment, has in making the front walking frame 100 and the rear walking frame 300 relative fixed, reach the beneficial effect that guarantee that the rotation misplacement between both sides does not occur, avoid the over positioning between both sides.

[0035] The segmented walking frame device 10 comprises front and rear walking frames 100, 300 and a positioning assembly between the front and rear walking frames 100, 300. The front and rear walking frames 100, 300 are provided with positioning grooves matched with two ends of the positioning assembly. The positioning assembly comprises a cylindrical pin 500 and a one-way positioning piece 700. The one-way positioning piece 700 is arranged along the radial direction of the cylindrical pin 500. The positioning groove at one end of the one-way positioning piece 700 is referred to as a second positioning groove 250. The second positioning groove 250 has a gap with the one-way positioning piece 700, which allows the one-way positioning piece 700 to deviate from the radial direction of the cylindrical pin 500 during assembly.

[0036] Based on the matching of the cylindrical pin 500 and the corresponding positioning groove, the relative position between the front walking frame 100 and the rear walking frame 300 is fixed. Meanwhile, based on the gap, when the one-way positioning piece 700 is over-positioned in a non-radial direction, the front and rear walking frames 300 can be automatically adjusted by rotating around the cylindrical pin 500, so that the entire device can be automatically corrected to the correct position. When the one-way positioning piece 700 is over-positioned in the radial direction, the gap between the second positioning groove 250 and the one-way positioning piece 700 allows the one-way positioning piece 700 to move in the radial direction of the cylindrical pin 500, thereby realizing correction in the radial direction.

[0037] That is, through the two mechanisms, the segmented walking frame device 10 provided by the present application can effectively cope with assembly errors in different directions while fixing the relative positions of the front walking frame 100 and the rear walking frame 300, significantly reducing the requirements for machining precision and position degree, and improving the assembly success rate and system stability. In addition, based on the above, the segmented walking frame device 10 provided by the present application has the beneficial effects of simple disassembly and assembly, low machining difficulty, high positioning accuracy, and long service life.

[0038] Alternatively, the positioning groove at the other end of the one-way positioning piece 700 is referred to as a first positioning groove 230, and the first positioning groove 230 matches the one-way positioning piece 700. That is, one end of the one-way positioning piece 700 is stably matched with one of the front and rear walking frames 100, 300 through the first positioning groove 230, ensuring that the end maintains a fixed position during use, thereby providing stable support. The other end of the one-way positioning piece 700 is gap-matched with the other of the front and rear walking frames 100, 300 through the second positioning groove 250, allowing a certain radial movement, increasing the flexibility of the system, and enabling the entire device to be automatically adjusted and corrected.

[0039] Considering the standardized design of the flat key and the key groove makes the assembly process more simple and fast, such as Figure 3 and Figure 4As shown, the one-way positioning member 700 is a flat key. The first positioning groove 230 and the second positioning groove 250 are correspondingly provided as key grooves. It should be noted that the flat key is specifically a square flat key, which is composed of four planes that are symmetric in pairs, and the corner portions can be designed as circular arcs, chamfers or other transition forms, and are not limited to right angles.

[0040] Further, the groove wall of the second positioning groove 250 includes first groove walls 251 that are spaced apart in parallel to the radial direction of the cylindrical pin 500, and at least one first groove wall 251 has a gap with the flat key, so as to allow the one-way positioning member 700 to be finely adjusted in the radial direction during assembly or use, thereby enabling the front walking frame 100 and the rear walking frame 300 to automatically adjust to the correct position within a certain range when encountering radial over-positioning.

[0041] Correspondingly, the groove wall of the second positioning groove 250 also includes two second groove walls 253 that are spaced apart in parallel to the tangential direction of the cylindrical pin 500, and both of the two second groove walls 253 are engaged with the flat key, so as to ensure that the one-way positioning member 700 remains fixed in the tangential direction. It should be easily understood that the tangential direction refers to the tangent direction, which is perpendicular to the radial direction with respect to the same radius.

[0042] Optionally, there is a gap between each of the two first groove walls 251 and the flat key, and the gap has a value range of 3 to 7 mm. It should be easily understood that the above-mentioned gap value range can provide sufficient radial freedom to enable the flat key to adaptively perform a small displacement, and also will not be too large to affect the overall stability and positioning accuracy of the segmented walking frame device 10. Preferably, the gap is 5 mm.

[0043] In some embodiments, the centers of the cylindrical pin 500 and the one-way positioning member 700 are located at the same horizontal height. It should be easily understood that in this case, the first groove wall 251 is spaced apart along the horizontal direction, and there is a gap between the flat key and the first groove wall 251 in the horizontal direction; and the second groove wall 253 is spaced apart along the vertical direction, and the side wall corresponding to the flat key is engaged.

[0044] Please refer again to Figures 1 to 4 , considering the overall stability of the assembled segmented walking frame, the segmented walking frame device 10 further includes a first fastening assembly 910 and a second fastening assembly 930. Similar to the first positioning groove 230 and the second positioning groove 250, the positioning groove corresponding to the cylindrical pin 500 is referred to as a pin hole 210. And the cylindrical pin 500 is connected with the pin hole 210 through the first fastening assembly 910, to avoid loosening due to vibration or impact. Correspondingly, the flat key is connected with the first positioning groove 230 through the second fastening assembly 930, to avoid displacement or falling during use.

[0045] Since the screw and the flat washer can effectively prevent the cylindrical pin 500 and the flat key from falling off during long-term use, the cylindrical pin 500 is optionally provided with a first positioning hole 510, and the first fastening assembly 910 includes a first flat washer 911 and a first screw 913, and the first screw 913 is connected with the bottom wall of the pin hole 210 in sequence by penetrating the first flat washer 911 and the first positioning hole 510. Similarly, the flat key is provided with a second positioning hole 710, and the second fastening assembly 930 includes a second flat washer 931 and a second screw 933, and the second screw 933 is connected with the bottom wall of the first positioning groove 230 in sequence by penetrating the second flat washer 931 and the second positioning hole 710.

[0046] In addition, it also needs to be pointed out that, in order to avoid the flat key rotating relative to the first positioning groove 230 and the second positioning groove 250 with the second screw 933 as the axis, the number of the second positioning hole 710 is two, and the two second positioning holes 710 are arranged along the radial direction of the cylindrical pin 500. Based on the above setting, the number and position of the second flat washer 931 and the second screw 933 are one-to-one corresponding to the second positioning hole 710.

[0047] As an optional embodiment, as shown in Figure 3 and Figure 4 , one end of the front walking frame 100 and the rear walking frame 300 adjacent to each other is respectively provided with a matching first connecting plate 110 and a second connecting plate 310. It is easy to understand that the design of the first connecting plate 110 and the second connecting plate 310 makes the connection between the front walking frame 100 and the rear walking frame 300 more modularized, so as to achieve the beneficial effects of simplifying the manufacturing and assembly process, facilitating the later maintenance and replacement of parts.

[0048] On this basis, the first positioning groove 230 is arranged in one of the first connecting plate 110 and the second connecting plate 310, and the second positioning groove 250 is arranged in the other one of the first connecting plate 110 and the second connecting plate 310. Correspondingly, the positioning grooves (i.e. pin holes 210) corresponding to the two ends of the cylindrical pin 500 are also arranged in the first connecting plate 110 and the second connecting plate 310, respectively. In addition, in the optional embodiment, the first connecting plate 110 and the second connecting plate 310 are both connecting flanges.

[0049] In order to further improve the overall stability of the segmented walking frame after assembly, the segmented walking device further includes a third fastening assembly 950, and the first connecting plate 110 is connected with the second connecting plate 310 through the third fastening assembly 950. Specifically, the first connecting plate 110 and the second connecting plate 310 are respectively provided with a third positioning hole 111 and a fourth positioning hole 311, and the third fastening assembly 950 includes a third flat washer 951, a bolt 953 and a nut 955, and the bolt 953 is connected with the nut 955 in sequence by penetrating the third positioning hole 111, the fourth positioning hole 311, the third flat washer 951.

[0050] In summary, the utility model provides a segmented walking frame, the segmented walking frame device 10 includes front, rear walking frame 100, 300 and positioning assembly, wherein, positioning assembly includes cylindrical pin 500 and one way positioning piece 700, and, one way positioning piece 700 is arranged along the radial direction of cylindrical pin 500, on this basis, the positioning groove of one way positioning piece 700 one end is recorded as second positioning groove 250, and, second positioning groove 250 and one way positioning piece 700 exist clearance, and this clearance is used to allow one way positioning piece 700 to deviate along the radial direction of cylindrical pin 500 when assembling, based on the above setting, the segmented walking frame device 10 provided in the application can effectively cope with assembly error in different directions while making front walking frame 100 and rear walking frame 300 relative fixed, significantly reduce the requirement to machining accuracy and position degree, improve assembly success rate and system stability.

[0051] In addition, the utility model further provides a tracked mobile equipment, specifically can be mine or roadway tunneling equipment, it includes supporting wheel and the segmented walking frame device 10 in the foregoing embodiment, and, supporting wheel is connected with front walking frame 100 and / or rear walking frame 300, it is easy to understand that based on the setting of the segmented walking frame device 10, the tracked mobile equipment can also effectively cope with assembly error in different directions while making front walking frame 100 and rear walking frame 300 relative fixed, significantly reduce the requirement to machining accuracy and position degree, improve assembly success rate and system stability, here will not repeat.

[0052] It also needs to be noted that after the above cylindrical pin 500 and one way positioning piece 700 connect front walking frame 100 and rear walking frame 300, the mounting surface of front walking frame 100 connected with supporting wheel is in the same plane with the mounting surface of rear walking frame 300 connected with supporting wheel, it is easy to understand that when the supporting wheel installed in front walking frame 100 and rear walking frame 300 is installed in the same plane, walking frame can provide more stable support in the process of marching, reduces the unstable phenomenon caused by height difference or inclination.

[0053] The above, only for the specific implementation of the utility model, but the protection scope of the utility model is not limited to this, any skilled person in the art in the technical range disclosed in the utility model, can easily think of the change or replacement, should be covered in the protection scope of the utility model.
