Description

Technical Field

[0001] This utility model relates to the field of mining technology, specifically a hole-laying device for open-pit mines. Background Technology

[0002] Open-pit mining involves stripping away the topsoil and surrounding rock covering the ore body, transporting waste rock to a spoil heap, and directly extracting ore from the exposed ore body. When the ore body is shallow or has an outcrop, open-pit mining is superior to underground mining. Open-pit mining consists of three stages: stripping, mining, and trenching. Its main production processes include: drilling, blasting, loading of ore (rock), transportation of ore and rock, and rock unloading. Drilling is the first step in open-pit mining, its purpose being to provide holes for placing explosives during blasting. The quality of drilling directly affects the efficiency of subsequent blasting, loading, and crushing operations.

[0003] An investigation revealed that a Chinese utility model patent discloses an open-pit mine hole-laying device (publication number: CN220895143U), which includes a fixing plate, support columns, and a battery. The bottom surface of the fixing plate has mounting grooves at both ends. Support columns are hinged to both sides of the two mounting grooves, and both support columns are located inside the mounting grooves. A ring-shaped LED light strip is fixedly installed on the top surface of the fixing plate. A telescopic rod is fixedly installed on the surface of the fixing plate inside the ring-shaped LED light strip. A reflective warning flag is fixedly installed on the top of the telescopic rod.

[0004] In the aforementioned patent, by providing a ring-shaped LED light strip and a reflective warning flag on the top of the fixed plate, and by hinged a support column at the bottom of the fixed plate, it is not only convenient to make holes for the device, but also allows the drilling operator to clearly observe the drilling position in any weather. However, when not in use, the LED light strip and reflective warning flag are exposed, and the exposed LED light strip is prone to accumulating dust and stains. These stains will block the light, thus causing the brightness of the light strip to decrease.

[0005] Therefore, this utility model provides a hole-laying device for open-pit mines to solve the above-mentioned problems. Utility Model Content

[0015] As a preferred technical solution of this application, a pull block is fixedly connected to one side of the box cover.

[0016] (III) Beneficial Effects

[0017] This utility model features a simple structure and convenient operation. Through the lifting mechanism and sliding cover, the rotating rod and half-sector gear can be driven to rotate synchronously. The rotation of the half-sector gear then pushes the connecting rod, causing the lifting platform to rise. Simultaneously, the ring-shaped LED light strip and reflective warning flag also rise. When not in use, these components can be stored inside the box, effectively preventing dust and stains from accumulating on the LED light strip and reducing the risk of decreased brightness.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] This utility model provides a hole-laying device for open-pit mines, such as... Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the hole-laying device for open-pit mines includes a fixed box 1, a box cover 2 that is slidably installed on the top of the fixed box 1, a lifting platform 7 installed inside the fixed box 1, a ring-shaped LED light strip 8 that is fixedly installed on the top of the lifting platform 7, a reflective warning flag 9 installed above the lifting platform 7, and a lifting mechanism installed inside the fixed box 1 for raising and lowering the lifting platform 7.

[0027] The lifting mechanism includes a fixed block 3 fixedly installed at the bottom of the box cover 2, a rotating rod 4 rotatably installed on the inner walls of both sides of the fixed box 1, a half-sector tooth 5 fixedly installed on one side of one of the rotating rods 4, a first connecting rod 6 fixedly installed on one side of the half-sector tooth 5, and a second connecting rod 10 rotatably installed on both sides of the lifting platform 7.

[0028] The end of the rotating rod 4 away from the inside of the fixed box 1 is rotatably connected to one side of the fixed block 3. Every two half-sector teeth 5 mesh, and the end of the first connecting rod 6 away from the half-sector teeth 5 is rotatably connected to the end of the second connecting rod 10 away from the lifting platform 7.

[0029] The fixing block 3, the half-sector tooth 5, the first connecting rod 6 and the second connecting rod 10 are symmetrically arranged inside the fixing box 1.

[0030] When using this open-pit mine hole-laying device, first place the fixed box 1 in a suitable position. Then, when the lifting platform 7 needs to be raised, slide the box cover 2 to both sides. The movement of the box cover 2 drives the four rotating rods 4 to rotate simultaneously. The rotating rod 4 drives the half-sector teeth 5 fixed to it to rotate. Since the two half-sector teeth 5 mesh with each other, the other rotating rod 4 will also rotate synchronously. The rotation of the half-sector teeth 5 further drives the first connecting rod 6 to rotate. The first connecting rod 6 pushes the lifting platform 7 to rise through the second connecting rod 10. Conversely, when the lifting platform 7 needs to be lowered, simply slide the box cover 2 inward. After the lifting platform 7 rises, the ring LED light strip 8 rises accordingly to provide illumination for the operator. The reflective warning flag 9 serves as a warning under the illumination, reminding the surrounding personnel to pay attention to safety. The operator can carry out hole-laying operations on the lifting platform 7. After the operation is completed, the lifting platform 7 is lowered back into the fixed box 1 through the lifting mechanism, and the box cover 2 is closed. The entire device is easy to carry and transport.

[0031] In order to facilitate the adjustment of the height of the reflective warning flag 9, such as Figure 1 , Figure 2 and Figure 3 As shown, a telescopic rod 11 is fixedly connected to the bottom inner wall of the fixed box 1, and the movable end of the telescopic rod 11 is fixedly connected to the bottom of the lifting platform 7.

[0032] An electric push rod 12 is fixedly connected to the bottom of the lifting platform 7. The movable end of the electric push rod 12 passes through the lifting platform 7 and is fixedly connected to the reflective warning flag 9.

[0033] When using this open-pit mine hole-laying device, the operator can adjust the height of the reflective warning flag 9 relative to the lifting platform 7 by controlling the extension and retraction of the electric push rod 12 to adapt to different working environments and lighting conditions. The precise control of the electric push rod 12 ensures that the reflective warning flag 9 can always be kept in the optimal warning position to effectively remind surrounding personnel. In addition, the setting of the telescopic rod 11 enhances the stability of the lifting platform 7.

[0034] Furthermore, to facilitate the sliding of the box cover 2, such as Figure 1 , Figure 2 and Figure 3 As shown, a pull block 13 is fixedly connected to one side of the box cover 2.

[0035] When using this open-pit mine hole-laying device, the operator can easily slide the box cover 2 off the fixed box 1 by holding the pull block 13.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
