Description

Technical Field

[0001] This utility model belongs to the field of tunnel support technology, and in particular relates to a square eight-petal lotus tray. Background Technology

[0002] Coal mining in my country is primarily underground, requiring the excavation of numerous roadways. Roadway support is crucial for maintaining roadway access and surrounding rock stability, significantly impacting mine construction and production. The fundamental purpose of roadway support is to mitigate and reduce rock movement, preventing excessive narrowing of the roadway cross-section and the collapse of loosened or damaged rock. However, the effectiveness of roadway support depends not only on the bearing capacity of the supports themselves but also on a range of factors, including the properties of the surrounding rock, the mechanical properties of the supports, the density of support installation, the timing of support installation, the quality of support installation, and the mode of contact between the supports and the surrounding rock.

[0003] Most existing roadway support anchor cable trays are hemispherical structures. Although they can provide support, their load-bearing capacity is poor. During use, the anchor cable trays will be damaged and deformed, which will reduce their service life and safety. Summary of the Invention

[0004] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a square eight-petal lotus tray, which can effectively solve the problems of the existing technology.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a square eight-petal lotus tray, including a tray main board, and also including:

[0007] The lotus-shaped tray is located at the center of the upper surface of the main tray, and a reinforcing member is fixed at the center of the lotus-shaped tray.

[0008] The multiple sets of reinforcing members are arranged in an arc shape, and the outer side of the reinforcing members is provided with reinforcing ribs that are inclined outwards.

[0009] The connecting hole is located in the center of the reinforcing member.

[0010] Furthermore, the outer surface of the lotus-shaped plate is uniformly provided with reinforcing members, and there are 8 sets of reinforcing members.

[0011] Furthermore, the lower end face of the tray main board is provided with a reinforcing groove, and there are 8 sets of reinforcing grooves, with reinforcing ribs provided between the multiple sets of reinforcing grooves.

[0012] Furthermore, the diameter of the groove in the reinforcing groove is larger than that of the reinforcing member, and the reinforcing member can be embedded inside another set of tray mainboards.

[0013] Furthermore, a connecting ring is fixed on one side of the upper end face of the tray main board, and the connecting ring is arranged in an arc shape.

[0014] This utility model has the following beneficial effects:

[0015] This utility model, by setting the reinforcing member in an eight-petal configuration and at an angle, achieves a higher load-bearing capacity and effective area load-bearing capacity than the spherical anchor cable trays used in the market. The main tray reduces product weight, simplifies usage steps, and enhances load-bearing capacity while ensuring comprehensive safety measures. Since the reinforcing member can be embedded in the reinforcement groove, multiple main trays can be stacked, making the main trays lighter, easier for workers to handle and install, while meeting the support requirements in mines, reducing safety risks, and simplifying operations.

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0024] Please see Figure 1-4 As shown, this utility model is a square eight-petal lotus tray, including a tray main board 1, and also including:

[0025] Lotus plate 2 is located at the center of the upper surface of the main plate 1, and a reinforcing member 3 is fixed at the center of the lotus plate 2. The main plate 1, lotus plate 2, and reinforcing member 3 are integrally die-cast, which ensures that the pallet has good load-bearing capacity. When the main plate 1 is used in conjunction with the excavator, anchor, and support integrated machine, there is no need to adjust the direction, which can reduce the work steps of adjusting the pallet angle, improve work efficiency, reduce labor costs, and improve the standardization level of on-site support. The outer surface of the lotus plate 2 is uniformly provided with reinforcing members 3, and there are 8 sets of reinforcing members 3. The reinforcing members 3 can be arranged in an eight-petal shape, which can increase the load-bearing capacity of the main plate 1. Its load-bearing capacity and effective area load-bearing capacity are higher than those of the spherical anchor cable pallets used on the market. The multiple sets of reinforcing members 3 are arranged in an arc shape, and the outer side of the reinforcing members 3 is provided with reinforcing ribs 4, which are inclined outward. Since there are no sharp edges, it is suitable for multi-angle installation, which not only facilitates downhole transportation and wellhead storage, but also effectively avoids mechanical damage caused by sharp edges, greatly reducing the safety hazards of on-site operation.

[0026] A connecting channel 5 is located in the center of the reinforcing member 3. The connecting channel 5 facilitates the subsequent connection of the anchor rod, thus facilitating subsequent installation. The lower end face of the pallet main plate 1 is provided with a reinforcing groove 6, and there are 8 sets of reinforcing grooves 6, with reinforcing ribs 7 between multiple sets of reinforcing grooves 6. The diameter of the groove of the reinforcing groove 6 is larger than that of the reinforcing member 3, and the reinforcing member 3 can be embedded in the inner side of another set of pallet main plates 1. The reinforcing member 3 can be embedded in the reinforcing groove 6 inside the pallet main plate 1, so that multiple sets of pallet main plates 1 can be stacked, making the pallet lighter, easier for workers to handle and install, while meeting the support requirements in the mine and reducing safety risks, reducing the difficulty of operation. At the same time, the reinforcing ribs 7 can also strengthen the pallet main plate 1, thereby further improving the load-bearing capacity of the pallet main plate 1.

[0027] A connecting ring 8 is fixed on one side of the upper end of the tray main board 1. The connecting ring 8 is set in an arc shape and has a raised edge design. While ensuring that the safety risk is not reduced, the two-time perforation operation procedure is simplified to a single perforation. The raised edge design greatly reduces the difficulty of perforation in complex environments, and also increases the production time by nearly double and greatly reduces the production process.

[0028] The above are merely preferred embodiments of the present utility model and do not limit the present utility model. Any modifications, equivalent substitutions, or improvements made to the technical solutions described in the foregoing embodiments, or to some of the technical features, shall fall within the protection scope of the present utility model.
