Description

Technical Field

[0001] The utility model relates to the technical field of anchor cable support, in particular to an adjustable anchor cable tray for mining. Background Art

[0002] The anchor cable support body is composed of steel strands, trays, locks, anchors and other components. The anchor cable tray is mainly used to compact the tunnel surface, spread the preload of the anchor cable, and achieve support for the tunnel.

[0003] An existing Chinese patent (publication number: CN221921025U) discloses a light-duty anchor cable pallet for mining, comprising a pallet body, a load-bearing end face, and reinforcing concave-convex ribs; the pallet body is circular; the load-bearing end face is arranged at the center of the pallet body, and the load-bearing end face and the pallet body are connected by a number of evenly distributed reinforcing concave-convex ribs. An anchor cable hole is provided in the center of the load-bearing end face, and the connection between the reinforcing concave-convex rib and the pallet body is semicircular. A center line is provided in the center of the reinforcing concave-convex rib. Compared with the traditional butterfly pallet, the circular pallet body can evenly distribute the bearing pressure of the anchor cable pallet, and the center line in the middle of the reinforcing concave-convex rib realizes the deepening and enlargement of the reinforcing concave-convex rib, so that the compressive strength of the pallet is higher and the bearing capacity is stronger, so that the entire anchor cable pallet is light in weight and small in size, which is convenient for on-site installation and use, and can also reduce costs.

[0004] During the use of the above-mentioned pallet, the strength of the pallet is further improved by the provided reinforcement ribs, but the size of the anchor hole in the center of the pallet for inserting the anchor cable cannot be adjusted. During the installation of the support mechanism, it is often necessary to pass the anchor cable through the anchor hole and use it in conjunction with the pallet to achieve a supporting effect. For this reason, the size of the anchor hole is often adapted to the anchor cable, so during the installation process, the operator needs to align the anchor cable with the anchor hole before inserting it. In the support process, when supporting the area at the top of the tunnel, the user often uses a lifting equipment to increase his own height, and then holds the anchor cable while aligning it with the anchor hole for insertion. If the diameter of the anchor hole is small and cannot be adjusted, the insertion operation is more difficult. Utility Model Content

[0005] The purpose of the utility model is to provide an adjustable mining anchor cable tray to solve the problems raised in the above background technology.

[0006] In order to solve the above technical problems, the utility model provides an adjustable mining anchor cable tray, including a tray body, including:

[0007] The mounting ring is connected to the pallet body, and its axis coincides with the center axis of the anchor hole opened on the pallet body;

[0008] There are multiple guide plates, which are connected to the mounting ring in a circular array with equal spacing around the center of the mounting ring. The multiple guide plates cooperate to form a frustum guide member for guiding the installation of the anchor cable. The inner diameter of the frustum guide member gradually decreases along the anchor cable installation path, and an installation groove is provided between every two guide plates.

[0009] A sealing component for sealing the frustum guide is also provided above the tray body.

[0010] Furthermore, the blocking component includes:

[0011] The connecting tube is connected to the tray body, and its axis coincides with the guide piece;

[0012] The telescopic cylinder is slidably connected to the connecting cylinder, and its inner surface is closely fitted with the outer surface of the guide piece;

[0013] The limiting bolt is threadedly connected to the connecting tube and is used to limit the telescopic tube.

[0014] Furthermore, at least two limiting threaded holes are provided on the connecting tube, and the limiting threaded holes and the limiting bolts are adapted to each other.

[0015] Furthermore, a connecting groove is provided on the top of the telescopic cylinder.

[0016] Furthermore, a plug-in slot is provided on the tray body, and at least two fixing bolts are threadedly connected to the plug-in slot.

[0017] Furthermore, the number of the plug-in slots is at least four, and they are distributed in a circular array with the axis of the tray body as the center.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] 1. The frustum guide is used to improve installation accuracy. Its gradually decreasing inner diameter design can guide the anchor cable to converge toward the center, ensuring that the anchor cable accurately enters the anchor cable hole and reducing installation deviation. In complex underground environments, especially when the operator's vision is obstructed or the operating space is limited, the anchor cable can still be guided smoothly into the hole. This setting reduces the time wasted due to repeated adjustments and ensures a smooth installation process.

[0020] 2. When injecting the anchoring agent after the pallet body is installed, the installation groove is sealed by pulling out the sealing plate to ensure that the anchoring agent can play a role in the required position and avoid material waste. The setting of the resistance turntable enhances the sealing stability of the sealing plate and limits the lifting and lowering sealing plate to make its position more stable during the sealing process.

[0021] 3. The plug-in slot can be used to install reinforcement plates of different lengths as needed, which can better adapt to the complex and changeable surrounding rock environment, enhance the adaptability of the tray to different geological conditions, optimize the support effect, and the fixing bolts facilitate the installation of the reinforcement plate, thereby improving installation efficiency and convenience.

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] See also Figure 1-4 The utility model provides a technical solution: an adjustable mining anchor cable tray, including a tray body 1, including:

[0029] The mounting ring 201 is connected to the pallet body 1, and its axis coincides with the center axis of the anchor hole opened on the pallet body 1;

[0030] There are multiple guide pieces 202, which are connected to the mounting ring 201 in a circular array with equal spacing around the center of the mounting ring 201. The multiple guide pieces 202 cooperate to form a frustum guide for guiding the installation of the anchor cable. An installation groove is provided between every two guide pieces 202;

[0031] A sealing assembly for sealing the frustum guide is also provided above the tray body 1 .

[0032] It should be noted that the guide piece 202 can be made of shape memory alloy, which can be used to facilitate storage by taking advantage of its ability to change shape.

[0033] In specific implementation, multiple guide plates 202 are connected to the mounting ring 201 in a circular array with equal spacing around the center of the mounting ring 201, together forming a conical guide. During the installation of the anchor cable, the anchor cable first contacts the conical guide. The inner diameter of the conical guide gradually decreases along the anchor cable installation path. When the anchor cable begins to be inserted, it first contacts the end with the larger inner diameter of the conical guide. As the anchor cable advances, the gradually decreasing inner diameter will have a guiding effect on the anchor cable to gather towards the center, ensuring that the anchor cable accurately enters the anchor cable hole of the tray body 1. As the anchor cable goes deeper, the conical guide can guide the anchor cable to move accurately in the direction of the anchor cable hole. This guiding effect is very important for ensuring the correct installation of the anchor cable in a complex underground environment, especially when the operator's vision is obstructed or the operating space is limited. The conical guide can help the anchor cable smoothly enter the anchor cable hole, reduce deviation during the installation process, and improve installation efficiency and accuracy.

[0034] See Figure 4 , the plugging components include,

[0035] The connecting tube 301 is connected to the tray body 1, and its axis coincides with the guide piece 202;

[0036] The telescopic cylinder 302 is slidably connected to the connecting cylinder 301, and its inner surface is tightly fitted with the outer surface of the guide piece 202;

[0037] The limiting bolt 303 is threadedly connected to the connecting cylinder 301 and is used to limit the telescopic cylinder 302.

[0038] During specific implementation, after the installation of the pallet body 1 is completed, it is necessary to inject an anchoring agent into it. In order to prevent the anchoring agent from leaking out, the telescopic cylinder 302 can be pulled out to seal the installation groove to prevent the anchoring agent from leaking out. The set limiting bolt 303 facilitates the limiting of the lifting telescopic cylinder 302, thereby improving the sealing stability of the telescopic cylinder 302.

[0039] See Figure 4 At least two limiting threaded holes are provided on the connecting tube 301 , and the limiting threaded holes and the limiting bolts 303 are adapted to each other.

[0040] During specific implementation, the two limiting threaded holes can be used in conjunction with each other to position the telescopic cylinder 302 in the blocked state and the opened state respectively.

[0041] See Figure 4 A connecting groove 6 is also provided on the top of the telescopic cylinder 302 .

[0042] During specific implementation, a sealing frame can be further inserted into the connection groove 6 to ensure the sealing effect.

[0043] refer to Figure 1 The tray body 1 is provided with an inserting slot 4 , and at least two fixing bolts 5 are threadedly connected to the inserting slot 4 .

[0044] It should be noted that the surrounding rock properties of different mine tunnels, such as hardness and degree of crack development, vary greatly. In some softer rock environments, a larger pallet bearing area is required to disperse the anchoring force of the anchor cable and prevent the pallet from sinking into the surrounding rock. However, in harder rock conditions, an oversized pallet may increase unnecessary costs and difficulty in installation.

[0045] During specific implementation, the provided plug-in slot 4 can be used to install reinforcement plates of different lengths as needed to better adapt to the surrounding rock environment, and the provided fixing bolts 5 facilitate the installation of the reinforcement plate. At the same time, a buffer pad can be connected to one side of the installed reinforcement plate. The buffer pad can be made of foam plastic, rubber, etc. to reduce the local pressure of the reinforcement plate.

[0046] refer to Figure 1 The number of the plug-in slots 4 is at least four, and they are distributed in a circular array with the axis of the tray body 1 as the center.

[0047] In specific implementation, this setting facilitates and better adjusts the position of the reinforcement plate according to needs.

[0048] Working principle: Multiple guide plates 202 are connected to the mounting ring 201 at equal intervals in a circular array with the center of the mounting ring 201 as the center, together forming a conical guide. During the anchor cable installation process, the anchor cable first contacts the conical guide. The inner diameter of the conical guide gradually decreases along the anchor cable installation path. When the anchor cable begins to be inserted, it first contacts the end with the larger inner diameter of the conical guide. As the anchor cable advances, the gradually decreasing inner diameter will have a guiding effect on the anchor cable to gather towards the center, ensuring that the anchor cable accurately enters the anchor cable hole of the tray body 1. As the anchor cable goes deeper, the conical guide can guide the anchor cable to move accurately in the direction of the anchor cable hole. This guiding effect is very important for ensuring the correct installation of the anchor cable in complex underground environments, especially when the operator's vision is obstructed or the operating space is limited. The conical guide can help the anchor cable smoothly enter the anchor cable hole, reduce deviations during the installation process, and improve installation efficiency and accuracy.

[0049] After the installation of the tray body 1 is completed, it is necessary to inject anchoring agent into it. To prevent the anchoring agent from leaking, the telescopic cylinder 302 can be pulled out to seal the installation groove, thereby preventing the anchoring agent from leaking. The provided limiting bolt 303 facilitates the positioning of the telescopic cylinder 302 when it is lifted and lowered, thereby improving the sealing stability of the telescopic cylinder 302.

[0050] The provided plug-in slot 4 can be used to install reinforcement plates of different lengths as needed to better adapt to the surrounding rock environment, and the provided fixing bolts 5 facilitate the installation of the reinforcement plate. At the same time, a buffer pad can be connected to one side of the installed reinforcement plate. The buffer pad can be made of foam plastic, rubber, etc. to reduce the local pressure of the reinforcement plate.
