Description

Technical Field

[0001] This utility model relates to the field of disassembly and replacement of track plates for open-pit mine drilling rigs, and in particular to a hollow track and a load-bearing frame for disassembly and assembly. Background Technology

[0002] Our company's drilling machines are all over 10 years old, and some tracks have shown severe wear. During maintenance, track pads need to be replaced, which is very difficult. When removing or installing track pads, the guide chain must be used to apply force from both sides of the track pad to the center so that the track pad pins can be removed without stress. Currently, the hooks on both sides of the guide chain lack reliable attachment points and can only be hooked onto the side of the track pad. This operation has the following problems: ① The hooks are not securely attached and can easily come loose and cause injury; ② The hook locking plates are ineffective. This greatly increases the risk of injury to workers. We have addressed these issues and made improvements to protect the health of workers and reduce hazards. To avoid the above problems, we analyzed the device and found that the original method caused injury due to unstable hooking. We will design a new structure to prevent unstable connection and achieve a safer operation. Utility Model Content

[0021] The purpose of this utility model is to provide a hollow track and a detachable load-bearing frame to solve the problems existing in the prior art. It has a simple structure, is easy to replace, and effectively improves the efficiency of maintenance work.

[0022] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0023] Example 1

[0024] This embodiment provides a hollow track, such as Figures 1-3As shown, the system includes: multiple hollow track plates 1 and multiple fixing pins 17. The front end of the hollow track plate 1 is provided with multiple receiving ears 2, and the receiving ears 2 are provided with force-bearing holes 3. The rear end of the hollow track plate 1 is provided with multiple connecting ears 4, and a connecting groove 5 is provided between adjacent connecting ears 4. The receiving ear 2 of one hollow track plate 1 is used to be placed in the connecting groove 5 of the adjacent hollow track plate 1. The connecting ear 4 is provided with a connecting hole 6. The side of the hollow track plate 1 is provided with an insertion groove 7. The fixing pins 17 are used to pass through the force-bearing holes 3 of the hollow track plate 1 and the connecting holes 6 of the adjacent hollow track plate 1 to connect two adjacent hollow track plates 1. This design makes the connection between the hollow track plates 1 more stable and orderly. The engagement of the receiving ear 2 with the connecting groove 5 and the connection of the connecting ear 4 with the fixing pin 17 provide a reliable mechanical connection structure for the track. This ensures that the track can withstand corresponding tensile and impact forces during operation, reducing track malfunctions such as disengagement due to unstable connections. This improves the overall stability and operational reliability of the track, meeting the operational needs of equipment such as open-pit mine drilling rigs. Furthermore, the insertion groove 7 can be used in conjunction with a pull-out load-bearing frame to effectively relieve stress on the fixing pin 17 between the track plates. This makes disassembling and installing the fixing pin 17 easier, significantly improving the replacement efficiency of the hollow track plates 1, shortening equipment maintenance time, reducing equipment downtime costs, and enhancing the continuity of production operations.

[0025] In a preferred embodiment, a reinforcing plate 15 is provided in the middle of the insertion groove 7. The reinforcing plate 15 can significantly enhance the structural strength of the insertion groove 7 of the hollow track plate 1. When used in conjunction with the pull-out load-bearing frame, the insertion groove 7 needs to withstand certain external forces and friction. The presence of the reinforcing plate 15 can prevent the insertion groove 7 from deforming and being damaged during frequent insertion operations or under stress, extend the service life of the hollow track plate 1, improve the overall structural durability, and ensure the normal use of the track under complex working conditions.

[0026] In a preferred embodiment, extension plates 16 are provided on both sides of the hollow track plate 1. These extension plates 16 increase the load-bearing area of ​​the hollow track plate 1, allowing the track to better distribute pressure from the ground or other components during operation. This helps reduce localized pressure concentration on the track, slows down localized wear, improves the overall load-bearing capacity of the track, enables the track to withstand greater loads, adapts to varying operational intensity requirements, and further enhances the stability and reliability of the equipment.

[0027] In a preferred embodiment, the front end of the receiving ear 2 is arc-shaped. The arc-shaped design can improve the strength of the front end of the receiving ear 2 and reduce the risk of breakage due to stress concentration. At the same time, the arc-shaped structure is smoother, which facilitates the docking and installation of the receiving ear 2 with the connecting groove 5 of the adjacent hollow track plate 1 during the connection process, reduces the resistance during docking, makes the connection operation smoother, and allows for better relatively flexible rotation of the two hollow track plates 1 between the fixing pins 17, which is beneficial for the track to adapt to the posture changes during equipment operation.

[0028] In a preferred embodiment, the rear end of the connecting ear 4 is arc-shaped. This arc-shaped design enhances the strength of the rear end of the connecting ear 4, preventing cracks or damage caused by long-term stress. This arc-shaped design allows for greater flexibility in connection with the fixing pin 17 and adjacent track plates, reducing wear during connection or rotation, ensuring the reliability of the overall track connection and the flexibility of track operation, and facilitating stable track operation under different working conditions.

[0029] Example 2

[0030] This embodiment also provides a detachable load-bearing bracket suitable for hollow tracks as described in any of Embodiment 1, comprising: a first pull-out load-bearing bracket 8, a second pull-out load-bearing bracket 9, and a fastening zipper 10. The first pull-out load-bearing bracket 8 is used to insert and fix itself into the insertion slot 7 of a hollow track plate 1, and the first pull-out load-bearing bracket 8 is provided with a first load-bearing hole 14; the second pull-out load-bearing bracket 9 is used to insert and fix itself into the insertion slot 7 of another hollow track plate 1, and the second pull-out load-bearing bracket 9 is provided with a second load-bearing hole; the fastening zipper 10 is used to pass through the first load-bearing hole 14 and the second load-bearing hole 15. The force-bearing holes can tighten the first pull-out force-bearing bracket 8 and the second pull-out force-bearing bracket 9 so that the fixing pins 17 between the first pull-out force-bearing bracket 8 and the second pull-out force-bearing bracket 9 are in an unstressed state. By accurately matching the pull-out force-bearing bracket with the insertion groove 7 of the hollow track plate 1, and then applying the pulling force by the fastening zipper 10, the fixing pins 17 between the track plates can be effectively unloaded, making the operation of disassembling and installing the fixing pins 17 easier, greatly improving the replacement efficiency of the hollow track plate 1, shortening the equipment maintenance time, reducing equipment downtime costs, and improving the continuity of production operations.

[0031] In a preferred embodiment, the first pull-out load-bearing frame 8 includes a first support leg 11, a first integral support plate 12, and a first tension lug 13. The first support leg 11 is used to match the insertion slot 7. The first integral support plate 12 is fixedly connected to one end of the first support leg 11. The first tension lug 13 is vertically fixed to the first integral support plate 12, and a first force-bearing hole 14 is provided at the top of the first tension lug 13. The second pull-out load-bearing frame 9 includes a second support leg, a second integral support plate, and a second tension lug. The second support leg is used to match the insertion slot 7. The second integral support plate is fixedly connected to one end of the second support leg. The second tension lug is vertically fixed to the second integral support plate, and a second force-bearing hole is provided at the top of the second tension lug. This specific structural design enables the pull-out load-bearing frame to achieve precise matching and reliable connection with the insertion slot 7 of the hollow track plate 1. The matching of the support leg with the insertion slot 7 ensures stability after insertion. The integral support plate and tension lug structure not only provide a reasonable load-bearing structure but also provide a suitable position for setting the force-bearing hole. The well-defined structural components enable the disassembly and assembly load-bearing frame to function accurately during use, further ensuring the accuracy and stability of the stress relief operation on the hollow track plate 1 fixing pin 17, and improving the reliability and efficiency of disassembly and assembly work.

[0032] In a preferred embodiment, the first support leg 11 is provided with a gap 18 that matches the reinforcing plate 15. This gap 18 allows the first pull-out load-bearing bracket 8 to form a stable structural fit with the reinforcing plate 15 after being inserted into the slot 7 of the hollow track plate 1. This gap 18 design ensures that the support leg will not interfere with the reinforcing plate 15 during the pull-out operation, while also allowing the pull-out load-bearing bracket a reasonable range of motion within the slot 7. This ensures the ease of installation and disassembly of the bracket, and allows it to share the pressure with the reinforcing plate 15 when the track plate is under stress, improving the stability and strength of the entire track structure connection and ensuring the reliability of the disassembly and assembly of the load-bearing bracket in practical applications.

The above description of the embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the idea of ​​this utility model. In summary, the content of this specification should not be construed as a limitation of this utility model.
