They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0042] like Figures 1-6 As shown, a mining excavator anti-slip device includes a first fixing part 1 and a second fixing part 2. The first fixing part 1 is detachably connected between the excavator's stroke parts, and the second fixing part 2 is disposed at the rear end of the excavator's stroke part and contacts the excavator's stroke part.

[0043] The second fixing part 2 is rotatably connected to the first fixing part 1, and the second fixing part 2 can extend to both sides along the longitudinal direction of the first fixing part 1; the second fixing part 2 is disposed on either side of the first fixing part 1.

[0044] The first fixing part 1 and the second fixing part 2 together form a limit mechanism for the excavator's travel section to prevent the mining excavator from slipping during operation.

[0045] In order to facilitate the limiting and fixing of the excavator's stroke portion by the compression clamping device 4 during use, the first fixing part 1 includes a fixing bracket 3 and a compression clamping device 4 that is detachably connected to the fixing bracket 3.

[0046] The detachable connection between the fixed bracket 3 and the compression clamping device 4 is a threaded connection.

[0047] The aforementioned compression clamping device 4 is detachably connected, making it easy to disassemble and replace during use.

[0048] To facilitate the compression and fixation of the excavator's stroke section during use, the fixed bracket 3 includes a "U"-shaped base 5 and a flexible connecting rope 6. The fixed bracket 3 serves as a connecting platform to connect the entire device. An internal threaded hole 7 is reserved on the end face of the fixed bracket 3. The compression clamping device 4 is threadedly connected to the internal threaded hole 7 and forms a symmetrical clamping space for the excavator's stroke section within the fixed bracket 3.

[0049] When clamping the excavator's stroke section, the aforementioned clamping device 4 is symmetrically arranged on both sides of the excavator's stroke section. The excavator's stroke section is clamped and fixed by turning the clamping devices 4 on both sides.

[0050] To facilitate braking during use, the first fixing part 1 also includes a braking device 8, which is V-shaped and cooperates with the flexible connecting rope 6, with the tail of the flexible connecting rope 6 hooked into the V-shaped groove.

[0051] The above-mentioned fixation is achieved by the flexible connecting rope 6 and the "V" shaped groove. The "V" shaped groove is placed horizontally and fixed with bolts.

[0052] To facilitate the fixing of the flexible connecting rope 6 and the "V" shaped groove during use, the "U" shaped base 5 can be made of metal. The tail of the "U" shaped base 5 is connected to the ear plate 9 with a connection hole by welding, which is used to facilitate the connection of the flexible connecting rope.

[0053] The flexible connecting rope 6 adopts a steel wire rope structure, and the flexible connecting rope 6 is firmly connected to the ear plate 9 by welding or riveting.

[0054] In order to facilitate movement towards the excavator's travel section through the threaded engagement of the connecting end with the internal threaded hole during use, the compression clamping device 4 includes a connecting end 10 and a clamping end 11 detachably connected to the connecting end 10. The connecting end 10 is a threaded rod structure, and the connecting end 10 is threaded into the internal threaded hole 7. A connecting handle 12 is fixedly provided on the side away from the clamping end 11.

[0055] The clamping end 11 on the extrusion clamping device 4 is a metal structure, the clamping end 11 is a cylindrical structure, and the clamping end 11 is connected to the friction pad 12 by adhesive bonding.

[0056] The clamping end 11 of the aforementioned extrusion clamping device 4 is equipped with a friction pad on the side of the contact surface with the equipment. The friction pad and the clamping device can be connected by means of adhesive or other methods. The friction pad is made of a highly elastic and high-friction material and needs to provide sufficient friction to ensure that the entire device can be firmly clamped on the mining excavator.

[0057] To facilitate positioning during use, the first fixing part and the second fixing part cooperate to limit the position. The second fixing part 2 includes a connecting plate 13. The end of the connecting plate 13 is connected to a support frame 14 with an arc-shaped structure. The end of the connecting plate 13 away from the support frame is rotatably connected to the "U"-shaped base 5 through a connecting rod 15.

[0058] The connecting rod 15 adopts a telescopic structure with sleeves at both ends, and is fixed in the positioning hole of the connecting rod 15 by bolts during positioning.

[0059] The connecting plate 13 can rotate via the connecting rod. When the clamping device 4 contacts the excavator's travel section, the extension and retraction of the connecting rod 15 causes the support frame to move closer to the outside of the excavator's travel section. The end face of the connecting plate 13 does not contact the clamping device 4, and the clamping device 4 does not interfere with the connecting plate 13. The connecting plate 13 is fixed by bolts using the same extension and retraction method as the connecting rod 15 (not shown in the figure).

[0060] The connecting plate 13 is a telescopic structure that is fixed by bolts, and the connecting rod 15 is a telescopic structure.

[0061] In order to facilitate the outward or inward movement of the support frame 14 by means of the connecting rod during use, the connection between the connecting rod 15 and the "U"-shaped base 5 is connected by a bearing. The bearing is fixed to the end face of the "U"-shaped base 5 to realize the rotatable connection between the connecting rod 15 and the "U"-shaped base 5.

[0062] The "U"-shaped base 5 is open at the end facing the excavator's travel section;

[0063] The support frame 14 is made of engineering plastic, and a protective layer 16 is wrapped around the support frame 14. The protective layer 16 is made of metal.

[0064] The support frame 14 has a honeycomb-like structure or a hollowed-out mesh structure on the side closest to the excavator's travel, while the upper part on the side furthest from the excavator's travel is a solid structure.

[0065] The outer side of the support frame 14 is connected to the connecting plate 13 by welding.

[0066] A method for using a mining excavator anti-slip device includes the following steps;

[0067] Place the first fixing part in front of the excavator's travel section. Since the first fixing part has an open structure, place the excavator's travel section in the center of the "U"-shaped base. Manually turn the squeezing clamping device. Since the squeezing clamping device has symmetrical clamping ends connected by connecting ends, clamp it inward through the clamping ends, firmly clamping the first fixing part onto the excavator's travel section, making it a stable connection platform. After confirming that the connection is secure, hook the braking device into the soft connecting rope for connection and use. After use, it can be disassembled by reversing the process.

[0068] When the first fixing part is tightened, the connecting plate is stretched outward, causing the connecting plate to move the support frame outward. After the first fixing part is tightened, the connecting plate is pushed inward, causing the connecting plate to move the support frame towards the excavator's travel part until it moves to the rear of the excavator's travel part. Since the connecting plate adopts a telescopic structure, it can be stretched or retracted appropriately according to the use needs, thereby causing the support frame to fit against the excavator's travel part at the rear end.

[0069] The combination of the first fixing part in front of the travel support of the mining excavator and the second fixing part behind the travel support of the mining excavator forms a slippage prevention structure, which can effectively prevent the slippage of the mining excavator during operation, improve the safety of operation, and has good application prospects.

[0070] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0071] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
