[0023] In order to make the purpose, technical solutions and advantages of this application more clearly understood, the following further describes this application in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0024] Before describing the various embodiments of the present application in detail, the technical concept of the present application will be briefly described first: Currently, in the process of relocating the rock conveying system, due to the narrow structure of the clamping block, it is difficult to fit tightly to the rails and sleeper rails, and the stress at the connection is too concentrated, which can easily lead to problems such as the rails tipping over and the fishtail plate breaking. For this reason, the present application provides a clamping block for the rock conveying system relocation rack, the clamping block includes a main body and a base, the support surface of the main body abuts the rails, the base abuts the sleeper rails, and the main body is fixed to the sleeper rails through mounting holes, so that the contact area between the clamping block and the sleeper rails and the rails can be increased to avoid excessive stress concentration. At the same time, the surface contact method can fit more tightly to the sleeper rails and the rails, increase the connection stability, and avoid situations such as the rails tipping over and the fishtail plate breaking. The specific principle of the clamping block for the rock conveying system relocation rack of the present application will be described below in conjunction with more embodiments.

[0025] Specifically, if Figure 1 、 Figure 2 、 Figure 3 As shown, the first embodiment of the present invention is a block for a rock transport system relocation rack, comprising a main body 10 and a base 20. The bottom surface of the main body 10 comprises a fixing surface 11 and a supporting surface 12. The main body 10 is provided with a mounting hole 13, which is used to be fixed to a sleeper 100. The base 20 is fixed to the fixing surface 11. The supporting surface 12 is located outside the base 20 and is used to abut against the rail 200. The base 20 is used to abut against the sleeper 100. For example, a mounting portion is provided on the sleeper 100. A fixing member is passed through the mounting hole 13 and the mounting portion to fix the main body 10 to the sleeper 100. At the same time, the base 20 is attached to the sleeper 100 and the supporting surface 12 is attached to the rail 200. This ensures that the stress at the attachment point is more dispersed, so that the rail 200 obtains a more uniform supporting force, prevents the rail 200 from bending or tipping under load, and improves the connection stability.

[0026] In one or more embodiments, the main body 10 is in the shape of a rectangular parallelepiped, the base 20 is in the shape of a quadrangular pyramid, and the bottom surface of the base 20 is connected to the fixed surface 11, and the top surface of the base 20 is used to abut against the sleeper 100, that is, the base 20 is an inverted quadrangular pyramid. Exemplarily, the top surface of the base 20 is a rough surface to increase the friction between the top surface of the base 20 and the sleeper 100 and improve the contact stability. The base 20 can make the main body 10 have a certain height so that the support surface 12 can face downward to fit the bottom of the rail 200 to ensure its stability. Exemplarily, the support surface 12 is a rough surface, which can enhance the friction between the support surface 12 and the rail 200.

[0027] In one or more embodiments, the mounting hole 13 extends through the side of the main body 10 in a direction parallel to the bottom surface of the main body 10. For example, the mounting hole 13 is a threaded hole, which can be fastened to the mounting portion of the sleeper 100 using bolts passing through the mounting hole 13, facilitating installation and removal. The mounting hole 13, the base 20, and the support surface 12 form a triangular support structure, ensuring that the clamping block is stably connected to the rail 200 and the sleeper 100.

[0028] In one or more embodiments, a portion of the top surface of the main body 10 is recessed to form an inclined surface 14, and the projection of the inclined surface 14 on the bottom surface of the main body 10 completely covers the support surface 12. By setting the inclined surface 14, an avoidance space can be formed between the main body 10 and the top of the rail 200. When the transfer wheel rotates along the top of the rail 200, it can avoid being blocked by the block, ensuring that the transfer wheel can rotate freely, improving the safety and reliability of the operation, and ensuring stability under dynamic load.

[0029] In one or more embodiments, the main body 10 and the base 20 are integrally formed to improve the overall strength of the block. For example, the main body 10 and the base 20 are both made of high-strength wear-resistant materials to improve the load-bearing capacity and durability of the block and reduce wear.

[0030] In one embodiment, Figure 4 and Figure 5 The structural dimensional parameters of the card block are shown. The length of the flat portion of the top surface of the main body 10 is 55 mm, the length of the inclined surface is 75 mm, the front end height of the main body 10 is 29.5 mm, the rear end height of the main body 10 is 61 mm, the diameter of the mounting hole 13 is 25 mm, the distance between the mounting hole 13 and the top surface of the main body 10 is 18 mm, the distance between the mounting hole 13 and the rear end of the main body 10 is 30 mm, the length of the fixing surface 11 is 82 mm, and the length of the support surface 12 is 48 mm. The length of the top surface of the base 20 is 72.5 mm, the length of the bottom surface of the base 20 is 82 mm, the height of the base 20 is 11 mm, the width of the top surface of the base 20 is 25 mm, and the width of the inclined surface of the base 20 is 10 mm.

[0031] The clamping block provided in this embodiment for use in the rock transport system relocation rack has a main body and a base that respectively make surface contact with the rails and sleeper rails, thereby reducing stress concentration at the connection, ensuring that the rails receive uniform support, preventing the rails from bending, tipping over, or even fishplate breakage, and improving connection stability. Specifically, the clamping block has the following technical effects:

[0032] (1) The block can effectively prevent the displacement of the I-rail, ensuring the normal operation of the earthmoving machine unloading vehicle. (2) When the belt conveyor is moved, the block ensures that the I-rail and the sleeper remain firmly connected, preventing the sleeper from detaching and ensuring the smooth progress of the relocation work. (3) Through the effective fixation of the block, the entire set of belt conveyor frame rails are safer and more stable during operation, reducing the phenomenon of belt deviation caused by vibration. (4) The block can evenly disperse the large loads generated during the movement of the earthmoving machine, and evenly distribute these loads to the track, thereby reducing the wear and deformation of the track. (5) The block can maintain the standard gauge of the track line, ensuring the stability and stability of the earthmoving machine during operation. (4) During the equipment relocation process, the block can prevent the rails from tipping over and the belt frame from deforming, ensuring a smooth and stable relocation process.

[0033] In actual use cases, when the original clamps were used during the relocation process, each relocation took 7 days. Due to quality problems with the clamps, they could fall, the rails could roll over, the rails could break, the fishplates could break, etc., adding 8 hours to each relocation. Quality problems or substandard clamps extended the relocation time, affecting production and causing delays of 3 to 4 days.

[0034] When the clamping block of this embodiment is applied: the time for each relocation is shortened to 3 to 4 days, the efficiency of relocation is improved, and each relocation saves 140,000 cubic meters of production, equivalent to RMB 665,000; 3 and a half days of maintenance time is saved, including the cost of 2 electricians, 1 welder and 4 fitters; the cost of 2 cleaning vehicle drivers is saved, and the equipment use and labor costs of 2 crawler bulldozers are saved; the labor cost and equipment diesel cost of 1 front-mounted equipment are saved; the cost of 3 sweepers is saved; the total cost savings for a single relocation is RMB 7.04684 million. The total number of relocations per year is 6 times, and the total cost savings for the whole year are RMB 42.28104 million. By adopting the clamping block of this embodiment, not only the time for each relocation is significantly shortened and production efficiency is improved, but also the maintenance and labor costs are greatly reduced. The cumulative cost savings for the whole year can reach several million yuan, which significantly improves the economic benefits.

[0035] The above describes in detail the specific implementation methods of the present application. Although some embodiments have been shown and described, those skilled in the art should understand that these embodiments can be modified and improved without departing from the principles and spirit of the present application, the scope of which is defined by the claims and their equivalents. These modifications and improvements should also be within the scope of protection of the present application.
