Description

Technical Field

[0001] This utility model relates to the field of engineering machinery technology, specifically to a material transfer device and inclined shaft tunnel construction equipment for inclined shaft tunnel construction. Background Technology

[0002] Currently, the construction of pumped storage inclined shafts in China is basically carried out using the traditional drill-and-blast method. This method uses only a simple work trolley, which serves only as a platform for personnel and materials, without any other additional functions. In traditional operations, materials are directly hoisted from a material transport trolley to the simple trolley. Due to the simple trolley's simple mechanism and relatively small size, most material handling is done manually, making material transfer relatively easy.

[0003] With the development of the times and the advancement of technology, the demand for intelligent and professional drilling and blasting trolleys is increasing, leading to the emergence of many intelligent integrated inclined shaft drilling and blasting construction equipment with functions such as mechanical rock drilling, cuttings removal, and high-altitude work platforms. However, due to the increase in functions, the size of the trolley has increased significantly, and the trolley passage is also occupied by these facilities. It is no longer possible to directly transport construction-related materials to the construction face at the bottom of the trolley by hand, as in the past. Therefore, higher requirements are placed on the transfer of drilling and blasting construction-related materials such as tracks, drill rods, anchor bolts, and explosives. Utility Model Content

[0004] To address the problems in the background technology, this utility model proposes a material transfer device for inclined shaft tunnel construction, which can automatically complete the material transfer work of drilling and blasting trolley construction in large inclined shaft construction, reduce labor intensity, and improve operational safety.

[0005] The present invention adopts the following technical solution:

[0006] A material transfer device for inclined shaft tunnel construction includes an upper extension support, a lower extension support, a track, a transfer trolley, and a lifting mechanism.

[0007] The upper and lower extension supports are located at both ends of the working trolley's travel direction. The track is installed on the working trolley and arranged along the working trolley's travel direction. Both ends of the track extend outside the working trolley, with the upper end laid on the upper extension support and the lower end laid on the lower extension support. The transfer trolley runs on the track and is used to carry materials for the inclined shaft tunnel construction. The working trolley has a transfer channel for the transfer trolley to travel from one end of the track to the other end. The lifting mechanism is fixed on the working trolley or the upper extension support and is connected to the transfer trolley for driving the transfer trolley to travel along the track.

[0008] Optionally, the bottom of the transfer trolley is provided with a slider, which is slidably mounted on the track.

[0009] Alternatively, the bottom of the transfer trolley is equipped with rollers, which roll on the track.

[0010] Optionally, the bottom of the slider has a groove, which is slidably disposed on a corresponding track.

[0011] Alternatively, the track has a groove, and the roller is rolled within the groove.

[0012] Optionally, the track has two rails arranged in parallel, and the sliders or rollers are also arranged in two rows, with multiple sliders or rollers in each row, and the multiple sliders or rollers are arranged at intervals along the travel direction of the work trolley.

[0013] Optionally, the lifting mechanism includes a winch, a pulley, and a wire rope. The winch is fixed to the bottom of the upper extension bracket, the pulley is rotatably installed at the rear end of the upper extension bracket, one end of the wire rope is fixed to the winch, and the other end passes through the winch and the pulley before being fixed to the transfer trolley.

[0014] Optionally, both the upper and lower ends of the track are equipped with locking mechanisms for locking the transfer trolley.

[0015] Optionally, the top of the transfer trolley and the rear end along the travel direction of the work platform are both provided with openings, and the front end of the transfer trolley along the travel direction of the work platform is provided with a baffle.

[0016] As a general inventive concept, this utility model also provides a construction equipment for inclined shaft tunnels, including a work trolley and the aforementioned material transfer device for inclined shaft tunnel construction.

[0017] Optionally, the track is mounted on the bottom support of the work trolley.

[0018] Optionally, it also includes a transfer trolley, which is located behind the working trolley in the direction of travel, and is equipped with a transfer crane for lifting the materials on it onto the transfer trolley.

[0019] Compared with the prior art, the advantages of this utility model are:

[0020] This utility model discloses a material transfer device for inclined shaft tunnel construction. By establishing a material transfer channel inside the trolley, a lifting mechanism transports materials from the top to the bottom of the trolley. Materials can be transferred from the trolley directly onto a material transfer trolley. With the assistance of the lifting mechanism, the material transfer trolley transports the materials to the bottom of the trolley via the internal material transfer channel. Once at the bottom, the materials can be manually or with the assistance of an auxiliary unloading crane to various required locations within the inclined shaft tunnel. This device solves the material transfer problem in new intelligent integrated inclined shaft drilling and blasting construction equipment, significantly reduces the number of manual handling operations, lowers labor intensity, and improves operational safety.

[0021] In addition, to facilitate the rapid and accurate hoisting of materials to the material transfer trolley by the transfer crane, this device is equipped with an upper extension bracket extending out of the work platform trolley. Furthermore, to facilitate the unloading of materials transferred in the material transfer trolley, this device is also equipped with a lower extension bracket extending out of the work platform trolley. Correspondingly, the track extends to the upper and lower extension brackets, so that the head and tail of the material transfer trolley can extend out of the work platform trolley to a large extent, thus establishing a complete material transfer channel, which can complete the material transfer work for drilling and blasting trolley construction operations in large inclined shafts.

[0032] The embodiments of the present invention are described below with reference to the accompanying drawings, so that those skilled in the art can better understand and implement the present invention. However, the listed embodiments are not intended to limit the present invention. In the absence of conflict, the following embodiments and the technical features in the embodiments can be combined with each other, wherein the same components are indicated by the same reference numerals.

[0033] Example 1

[0034] like Figures 1-6 As shown, this embodiment provides a material transfer device for inclined shaft tunnel construction, including an upper extension support 1, a lower extension support 2, a track 5, a transfer trolley 6, and a lifting mechanism 3.

[0035] The upper extension bracket 1 and the lower extension bracket 2 are respectively located at both ends of the working trolley's travel direction. The track 5 is installed on the working trolley 4 and arranged along the working trolley 4's travel direction. Both ends of the track 5 extend outside the working trolley, with its upper end laid on the upper extension bracket 1 and its lower end laid on the lower extension bracket 2. The transfer trolley 6 runs on the track 5 and is used to carry materials for the inclined shaft tunnel construction. The working trolley has a transfer channel 42 for the transfer trolley 6 to travel from one end of the track 5 to the other end of the track 5. The lifting mechanism 3 is fixed on the working trolley or the upper extension bracket 1 and is connected to the transfer trolley 6 for driving the transfer trolley 6 to travel along the track 5.

[0036] Therefore, by establishing a material transfer channel inside the trolley, a lifting mechanism is used to transport materials from the top to the bottom of the trolley. Materials can be transferred from the trolley directly onto a material transfer trolley. With the assistance of the lifting mechanism, the material transfer trolley transports the materials to the bottom of the trolley via the internal material transfer channel. Once the materials reach the bottom of the trolley, they can be moved manually or with the assistance of an auxiliary unloading crane to various required locations in the inclined shaft tunnel. This device solves the material transfer problem in new intelligent integrated inclined shaft drilling and blasting construction equipment, significantly reduces the number of manual handling operations, lowers labor intensity, and improves operational safety.

[0037] In addition, to facilitate the rapid and accurate hoisting of materials to the material transfer trolley by the transfer crane, this device is equipped with an upper extension bracket extending out of the work platform trolley. Furthermore, to facilitate the unloading of materials transferred in the material transfer trolley, this device is also equipped with a lower extension bracket extending out of the work platform trolley. Correspondingly, the track extends to the upper and lower extension brackets, so that the head and tail of the material transfer trolley can extend out of the work platform trolley to a large extent, thus establishing a complete material transfer channel, which can complete the material transfer work for drilling and blasting trolley construction operations in large inclined shafts.

[0038] like Figure 5 and Figure 6 As shown, in this embodiment, there are two tracks 5 arranged in parallel. Each track 5 has a groove 51 extending along its length, with the openings of the grooves 51 on the two tracks facing each other. The bottom of the transfer trolley 6 is equipped with rollers 61, arranged in two rows. Each row has multiple rollers 61, spaced apart along the travel direction of the work trolley. Each row of rollers 61 slides within the groove 51 of its corresponding track 5. This design not only ensures the smooth movement of the transfer trolley 6 but also provides a compact structure, facilitating its placement within the limited space of the work trolley 6's transfer channel 42.

[0039] In other embodiments, a slider with a groove 51 can also be provided at the bottom of the transfer trolley 6, and the groove 51 is slidably disposed on the corresponding track 5.

[0040] In this embodiment, the lifting mechanism 3 includes a winch 31, a pulley 32, and a wire rope 33. The winch 31 is fixed to the bottom of the upper extension bracket 1. The pulley 32 is rotatably installed at the rear end of the upper extension bracket 1. One end of the wire rope 33 is fixed to the winch 31, and the other end passes through the winch 31 and the pulley 32 before being fixed to the transfer trolley 6. The upper extension bracket 1 is fixed to the rear end of the work platform trolley through the side plate 11.

[0041] The hoist 31 and pulley 32 of the lifting mechanism 3 are both arranged on the upper extension bracket 1. On the one hand, this can save space for the work trolley 4, and on the other hand, it can ensure that the transfer trolley 6 can travel to the rear end of the track 5, so that most of its head structure extends out of the work trolley 4, which is convenient for loading materials.

[0042] In this embodiment, to avoid the risk of the transfer trolley 6 falling uncontrollably due to the failure of the winch 31, locking mechanisms (not shown in the figure) can be provided at both the upper and lower ends of the track 5 to lock the transfer trolley 6. Conventional track brakes can be used for the locking mechanisms, which will not be described in detail here.

[0043] In this embodiment, to facilitate the loading of materials, the top of the transfer trolley 6 and the rear end along the travel direction of the work platform 4 are both provided with openings. In addition, to prevent materials from falling during the transfer process by the transfer trolley 6, the front end of the transfer trolley 6 along the travel direction of the work platform 4 is provided with a baffle 62.

[0044] Example 2

[0045] This embodiment provides a construction equipment for inclined shaft tunnels, including a work trolley 4 and a material transfer device for inclined shaft tunnel construction as described in Embodiment 1.

[0046] In this embodiment, in order to facilitate the loading / unloading of materials and to avoid interference of the material transfer device with other working devices 10 at the front end of the work trolley 4, the track 5 is installed on the bottom support 41 of the work trolley 4.

[0047] In this embodiment, as Figure 7 As shown, it also includes a transfer trolley 7, which is located behind the working trolley 4 in the direction of travel. The transfer trolley 7 is equipped with a transfer crane 71 for lifting the materials 8 on it onto the transfer trolley 6.

[0048] The work trolley 4 is located inside the excavated inclined shaft 9. The bottom surface of the inclined shaft 9 is paved with steel plates as the track surface for the work trolley 4 to travel on. Each section of the inclined shaft needs to be excavated, and operations such as anchoring, grouting, hanging protective netting, laying tracks, and placing explosives are required. Previously, all of these operations required manual handling of construction materials to the working surface at the bottom of the trolley, which was dangerous and labor-intensive.

[0049] This invention adds the material transfer device of Embodiment 1 to the work trolley 4. Before loading materials, the transfer trolley 6 is lifted to the rear end of the work trolley 4 by a hoisting mechanism, with most of its head extending outside the work trolley 4. The materials 8 on the transfer trolley 7 are lifted by the transfer crane 71 on the transfer trolley 7 into the transfer trolley 6. Then, the hoisting mechanism lowers the transfer trolley 6, and the transfer trolley 6 slides along the track 5 to the rear end of the work trolley 4, with most of its tail extending outside the work trolley 4, so that the materials on the transfer trolley 6 can be unloaded. Figure 7 As shown, construction workers can be transported to the front of the work platform 4 by the high-altitude work device installed on the upper end of the work platform 4. After the construction workers get down from the work basket, they can unload the materials in the transfer trolley 6. Alternatively, the materials can be dropped from the transfer trolley 6 to the construction work position in front of the tunnel by opening the baffle 62 at the front of the transfer trolley 6, and the construction workers can then complete the subsequent construction operations.

The terms "in one embodiment," "in another embodiment," "in yet another embodiment," or "in still another embodiment" used in this specification all refer to one or more of the same or different embodiments according to this disclosure.
