[0027] Embodiment 1, refer to Figure 1 - Figure 4, which is the first embodiment of the present utility model, provides a crawler frame for a coal mining roadheader. This device includes a moving unit 100, which includes a crawler frame 101; a limiting unit 200, which includes a first limiting plate 201 arranged on one side of the crawler frame 101, a first limiting component 207 arranged on one side of the first limiting plate 201, a second limiting plate 208 arranged corresponding to the first limiting plate 201, and a second limiting component 209 arranged on one side of the second limiting plate 208. The first limiting component 207 and the second limiting component 209 are respectively installed on the outer sides of the first limiting plate 201 and the second limiting plate 208. Furthermore, the first limiting component 207 and the second limiting component 209 are used in combination to limit the moving crawler 103, thereby preventing the moving crawler 103 from falling off during the walking process and increasing the use stability of the moving crawler 103.
[0028] Among them, the first limiting component 207 includes a limiting plate main body 207a arranged on one side of the first limiting plate 201 and a limiting wheel 207b arranged on the limiting plate main body 207a. The moving crawler 103 is limited by the limiting wheel 207b, thereby preventing the moving crawler 103 from breaking away during the walking process. At the same time, the limiting plate main body 207a is protected, and further, the use safety and service life of the limiting plate main body 207a are increased.
[0029] During the use process, after the staff waits for the moving crawler 103 to be installed on the crawler frame 101, then the first limiting plate 201 is installed on one side of the crawler frame 101, and then the second limiting plate 208 is installed on the other side of the crawler frame 101, and the first limiting plate 201 and the second limiting plate 208 are overlapped. Then, the fixing bolts 202 sequentially pass through the first limiting plate 201 and the second limiting plate 208, thereby fixing the two to the bottom of the crawler frame 101. Then, the limiting plate main body 207a is installed on the outer side of the first limiting plate 201 and fixed by a first bolt 207c. Similarly, the second limiting component 209 is fixed to the outer side of the second limiting plate 208, so that the limiting plate main body 207a and the second limiting component 209 limit the moving crawler 103 on both sides, preventing the moving crawler 103 from falling off during the walking process and increasing the use stability of the moving crawler 103; at the same time, the limiting wheel 207b is on the side of the limiting plate main body 207a close to the moving crawler 103. When the moving crawler 103 moves outward and contacts the limiting wheel 207b, at this time, the moving crawler 103 will first touch the limiting wheel 207b, and the limiting wheel 207b is rotating, so that the limiting wheel 207b enables the moving crawler 103 to continue to move forward, so that the moving crawler 103 is reset again, further preventing the moving crawler 103 from breaking away during the walking process.
[0030] Embodiment 2, refer to Figure 1 - Figure 4, which is the second embodiment of the present utility model. The difference between this embodiment and the first embodiment is as follows: It includes a first bolt 207c arranged on the main body 207a of the limit plate. A connection groove 205 corresponding to the connection block 207d is provided on one side of the first limit plate 201. A bolt groove 206 corresponding to the second bolt 207e is provided on the first limit plate 201. A protruding block 204 corresponding to the crawler frame 101 is provided at one end of the first limit plate 201. A top support wheel 203 is provided at the top of the first limit plate 201 and the second limit plate 208. The main body 207a of the limit plate is fixed to the outside of the first limit plate 201 from the side by the first bolt 207c, and the main body 207a of the limit plate is fixed to the outside of the first limit plate 201 from the front by the second bolt 207e passing through the bolt groove 206 and the connection block 207d. Thus, the main body 207a of the limit plate can be firmly fixed on the first limit plate 201, increasing its use stability.
[0031] Among them, a fixing bolt 202 located inside the crawler frame 101 is provided at the intersection between the first limit plate 201 and the second limit plate 208. The number of the fixing bolts 202 is at least two groups. The first limit plate 201 and the second limit plate 208 are fixed to the top of the crawler frame 101 by the fixing bolts 202. The multiple groups of fixing bolts 202 make their connection more stable and firm, thereby increasing the safety and stability of the first limit plate 201 and the second limit plate 208 during use.
[0032] During use, the staff first install the first limiting plate 201 on one side of the crawler frame 101, then install the second limiting plate 208 on the other side of the crawler frame 101, and then fix the two to the top of the crawler frame 101 through multiple groups of fixing bolts 202. The multiple groups of fixing bolts 202 make their connection more stable and firm, thereby increasing the safety and stability of the first limiting plate 201 and the second limiting plate 208 during use. Then, align the connecting block 207d with the connecting groove 205, install the limiting plate body 207a on the outside of the second limiting plate 208, insert the connecting block 207d into the connecting groove 205, and then fix the limiting plate body 207a to the outside of the first limiting plate 201 from the side through the first bolt 207c. At the same time, pass the second bolt 207e through the bolt groove 206 and the two connecting blocks 207d, and then fix the limiting plate body 207a to the outside of the first limiting plate 201 from the front, so that the limiting plate body 207a can be firmly fixed to the outside of the first limiting plate 201, making it more stable and firm when the limiting wheel 207b limits the moving crawler 103, and ensuring the stability of the moving crawler 103 during walking. At the same time, the protruding block 204 at one end of the first limiting plate 201 makes there be no gap between the first limiting plate 201 and the crawler frame 101, thereby reducing the vibration between the first limiting plate 201 and the crawler frame 101 when the moving crawler 103 collides with the limiting wheel 207b, and further ensuring the use stability of the first limiting plate 201 and the first limiting component 207.
[0033] The rest of the structure is the same as that of Embodiment 1.
[0034] Embodiment 3, referring to Figure 1 - Figure 4 This is the third embodiment of the present invention. The difference between this embodiment and the first embodiment is that rotating mechanisms 105 are provided on both sides of the crawler frame 101, a moving crawler 103 is provided on the outside of the crawler frame 101, a rack column 104 is provided on the outside of the moving crawler 103, and crawler grooves 106 located in the middle of the rack column 104 are equidistantly opened on the outside of the moving crawler 103. By rotating the rotating mechanism 105, the moving crawler 103 on its outside is driven to rotate on the outside of the crawler frame 101, so that the crawler frame 101 walks and moves on the ground.
[0035] Compared with Embodiment 2, further, bottom support wheels 102 located on the moving crawler 103 are equidistantly provided at the bottom of the crawler frame 101. The bottom support wheels 102 make a certain distance exist between the bottom of the crawler frame 101 and the moving crawler 103, preventing friction between the moving crawler 103 and the bottom of the crawler frame 101 and damaging the moving crawler 103, and increasing the use safety and service life of the moving crawler 103.
[0036] During use, first install the moving track 103 at the bottom of the track frame 101, then install the rotating mechanism 105 on both sides of the track frame 101, then install the rack columns 104 equidistantly on the outside of the moving track 103, and then open track grooves 106 equidistantly on the outside of the moving track 103. Then install the moving track 103 on the track frame 101. When the rotating mechanism 105 rotates to control the movement of the moving track 103, at this time, the moving track 103 will be tightened on the outside of the track frame 101, and there is a certain distance between the bottom of the track frame 101 and the inner wall of the moving track 103. At this time, the bottom support wheel 102 will distribute the weight of the track frame 101 and the rotating mechanism 105 on the moving track 103 at the bottom of the track frame 101, thereby preventing the moving track 103 at the bottom from detaching from the track frame 101. At the same time, the bottom support wheel 102 reduces the friction between it and the moving track 103, so as not to cause resistance to the rotation and movement of the moving track 103 on the outside of the track frame 101. And the bottom support wheel 102 keeps a certain distance between the bottom of the track frame 101 and the moving track 103, preventing friction between the moving track 103 and the bottom of the track frame 101 and damaging the moving track 103, increasing the use safety and service life of the moving track 103. It should be particularly noted that the inner side of the moving track 103 is provided with grooves on both sides of the track groove 106 and corresponding to the bottom support wheel 102, so that during the movement of the moving track 103, the bottom support wheel 102 can also limit the moving track 103 at the bottom of the track frame 101; then install the first limiting plate 201 and the second limiting plate 208 on both sides of the track frame 101 respectively, and install the first limiting component 207 and the second limiting component 209 on the outside of the first limiting plate 201 and the second limiting component 209 respectively to limit and fix the moving track 103 above the track frame 101, and then cooperate with multiple groups of bottom support wheels 102 to limit the moving track 103 on both the upper and lower sides of the track frame 101 to prevent it from detaching during the movement process.
[0037] The rest of the structure is the same as that of Embodiment 2.
[0038] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
