Description

Technical Field

[0001] This utility model relates to the field of underground rescue equipment technology, specifically to a modular large-diameter casing transfer device. Background Technology

[0002] Horizontal rescue drilling rigs are crucial rescue equipment for quickly creating horizontal escape routes after engineering collapses. They employ a casing drilling method with a spiral shaft for slag removal, ultimately extracting the spiral shaft while leaving the casing inside the collapsed area to form an escape route. This effectively reduces secondary collapses and injuries caused during drilling and is currently the safest, most reliable, and most efficient mechanized rescue equipment for coal mine and tunnel engineering collapses.

[0003] The drilling tools used in horizontal rescue drilling rigs (cylindrical, but also suitable for casing and auger shafts) typically have a diameter greater than 600mm, a length greater than 1m per section, and a weight greater than 1t per section. Since a single rescue operation generally requires dozens of drilling tool sections, and transportation conditions in coal mines and tunnels limit the efficiency of these operations, the transport of these numerous drilling tools to the underside of the horizontal rescue drilling rig's boom becomes a significant factor affecting the overall efficiency of the rescue operation. Once the horizontal rescue drilling rig arrives at the rescue site, the limited tunnel dimensions often prevent mechanized equipment from turning around between the rig and the tunnel profile. The only solution is to manually pull small trailers back and forth, transporting the drilling tools section by section, which is labor-intensive and inefficient. Utility Model Content

[0004] The purpose of this utility model is to provide a modular large-diameter casing transfer device to solve the technical problem of inconvenient transportation of drilling tools (casing) during horizontal rescue operations in the prior art. The specific technical solution is as follows:

The two sides of the transfer frame are higher than the middle, and the width of the transfer frame is not less than the radius of the sleeve. The two sets of roller assemblies are arranged in a V-shape inside the transfer frame. Each set of roller assemblies includes multiple rollers, which are spaced apart and rotatably mounted on the transfer frame.

[0024] The embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0025] See Figures 1-6 As shown, a modular large-diameter sleeve transfer device includes a transfer frame 1 and two sets of roller assemblies. The two sides of the transfer frame 1 are higher than the middle part, and the width of the transfer frame 1 is not less than the radius of the sleeve 7. The two sets of roller assemblies are arranged in a V-shape inside the transfer frame 1. Each set of roller assemblies includes multiple rollers 3, which are spaced apart and rotatably mounted on the transfer frame 1.

[0026] Specifically, the arrangement of the idler roller 3 can be changed from a V-shaped structure to a concave structure according to the actual site conditions. The idler roller 3 can also be replaced with other customized idler rollers 3 or guide balls according to the actual site conditions. In this embodiment, the drill bit of the rescue machine is cylindrical in shape, similar to the structure of the casing 7, so the structure of this utility model can also be used for the transportation of the casing 7.

[0027] Preferably, the transfer frame 1 includes a base frame and two vertical frames, which are fixed to both sides of the base frame. The height of the vertical frames is higher than that of the base frame, so that the rollers 3 can be arranged in a V-shape, thereby supporting the sleeve 7 and ensuring the stable movement of the sleeve 7, preventing the sleeve 7 from rolling out of the transfer frame 1.

[0028] Preferred, such as Figure 5 As shown, a diagonal brace is fixed between the vertical frame and the base frame, which can improve the stability of the vertical frame.

[0029] Preferred, such as Figure 3 As shown, the vertical frame is fixed with multiple first clamping plates 2 for mounting the idler roller 3. The first clamping plate 2 has a V-shaped structure, with the end extending to form an extension plate. The extension plate has openings, and the first clamping plate 2 can be fixed to the inner side of the top of the vertical frame by bolts passing through the openings. The first clamping plate 2 has a first groove for mounting the idler roller 3 at the bend. By cooperating with the first clamping plates 2 on the transfer frame 1, the idler roller 3 is limited and fixed.

[0030] Preferably, a plurality of second clamping plates 4 for mounting the idler roller 3 are fixed in the middle position of the base frame. The second clamping plates 4 are also V-shaped. The second clamping plates 4 are provided with second slots for mounting the idler roller 3. The second slots extend to both sides of the bend so that the two sets of idler roller assemblies can be fixed at the same time.

[0031] Preferably, the base frame is provided with a protruding strip 6 for fixing the second clamping plate 4. The cross-section of the protruding strip 6 is triangular. The two ends of the second clamping plate 4 are provided with V-shaped openings. The V-shaped openings are clamped on the protruding strip 6 and fixed, so that the height of the lower end of the idler roller 3 is higher than the height of the base frame, thereby making it easier for the sleeve 7 to contact the idler roller 3.

[0032] Preferably, the idler roller 3 includes a rotating shaft, a bearing, and a roller body. The bearing is mounted on the rotating shaft, the roller body is mounted on the bearing, and the rotating shaft is mounted on the first clamping plate 2 and the second clamping plate 4. The arrangement of the rotating shaft and bearing allows the roller body to rotate easily around the rotating shaft.

[0033] Preferably, the transfer frame 1 is provided with connecting flanges 5 at both ends. Multiple transfer frames 1 can be connected in series through the connecting flanges 5, thereby increasing the length of the transfer frame 1.

[0034] During installation, the first clamping plate 2 is installed on the transfer frame 1, and the idler roller 3 is clamped on the first clamping plate 2 and the second clamping plate 4 to complete the assembly of the large diameter sleeve transfer device.

[0035] like Figure 4 As shown, multiple large-diameter sleeve transfer frames 1 are assembled according to the above steps as needed, and multiple large-diameter sleeve transfer devices are transferred to the predetermined positions. Each large-diameter sleeve transfer frame 1 is connected in sequence through the connecting flange 5 to achieve modular assembly.

[0036] like Figure 6 As shown, multiple large-diameter casing transfer devices are sequentially connected to an open area behind the horizontal rescue drilling rig construction area 8. In the open area, the casing 7 can be easily transferred to the transfer frame 1 without affecting the construction of the horizontal rescue drilling rig in front. After a section of the drilling rig is installed, the next casing 7 can be transferred to the bottom of the vehicle-mounted boom simply by gently pushing it.

[0037] This utility model relates to a modular large-diameter casing transfer device. By placing the casing 7 on V-shaped idler rollers 3 and pushing the casing 7, it can be moved and transported on the idler rollers 3, solving the technical problem of inconvenient casing transportation during horizontal rescue operations in the prior art. This utility model has a simple and lightweight structure, can be modularly assembled and disassembled, and is small in size, making it convenient for use in narrow tunnels. The transportation method of this utility model reduces labor intensity and improves overall rescue efficiency.

[0038] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
