Description

Technical Field

[0001] The invention relates to a high-strength anchor cable positioning bearing tray and a use method thereof, belonging to the technical field of support operations. Background Art

[0002] At present, anchor cables are widely used in structural support operations such as slopes and mine tunnels. The pallets currently used in anchor cable positioning and installation operations often adopt traditional pallet structures. Since traditional pallet structures are often traditional disc structures or truncated cone structures, although they can meet the needs of anchor cable equipment positioning and installation operations, on the one hand, the pallet has poor sealing ability for drilling holes, resulting in low pressure for drilling grouting operations and easy leakage of grouting slurry; on the other hand, during operation, traditional pallet structures have poor strength and elastic deformation capabilities, which causes the anchor cable structure to be affected by external force impact and geological deformation factors, causing the pallet to bear a large impact force, which seriously affects the stability and reliability of the pallet for anchor cable positioning.

[0003] Therefore, in view of this situation, there is an urgent need for a new pallet and a method for using the same to meet the needs of actual use. Summary of the invention

[0004] The purpose of the present invention is to overcome the above-mentioned shortcomings and provide a high-strength anchor cable positioning load-bearing tray and a method of using the same.

[0005] To achieve the above object, the present invention is implemented through the following technical solutions:

[0007] Furthermore, the axial cross-section and cross-section of the strengthening groove are both groove structures of any one of an inverted rectangle, an isosceles trapezoid, and an arc structure, the depth of the strengthening groove is not less than 5 mm, and a deformation groove with a rectangular cross-section is provided at the bottom of the strengthening groove. The deformation groove is coaxially distributed with the lower end face of the strengthening groove, and its length is 30%-90% of the length of the lower end face of the strengthening groove, and its width is 1-5 mm, and the area of ​​the deformation groove is not greater than 3%-20% of the area of ​​the lower end face of the strengthening groove.

[0008] Furthermore, the deformation groove is further provided with a plurality of auxiliary deformation grooves, and there are at least two auxiliary deformation grooves, which are evenly distributed along the axis direction of the deformation groove, and the auxiliary deformation grooves are connected with the deformation groove and are distributed perpendicularly to each other.

[0009] Furthermore, the upper end surface of the carrying tray is connected to the lower end surface of the guide positioning sleeve and forms an integrated structure. The inner diameter of the carrying tray is 30%-90% of the inner diameter of the guide positioning sleeve. The lower end surface of the carrying tray is provided with at least two elastic sealing rings of annular structure coaxially distributed with the carrying tray. The elastic sealing ring is at least 5 mm higher than the upper end surface of the carrying tray, and the area of ​​the elastic sealing ring is 50%-90% of the area of ​​the upper end surface of the carrying tray.

[0010] Furthermore, an elastic sealing plate is provided on the lower end surface of the carrier tray, and the elastic sealing plate is embedded in the lower end surface of the carrier tray and connected to the inner side surface of the carrier tray.

The deformation groove 5 is coaxially distributed with the lower end face of the strengthening groove 4, and its length is 30%-90% of the length of the lower end face of the strengthening groove 4, and its width is 1-5 mm, and the area of ​​the deformation groove 5 is not greater than 3%-20% of the area of ​​the lower end face of the strengthening groove 4.

[0022] For further optimization, the deformation groove 5 is further provided with a plurality of auxiliary deformation grooves 6, wherein there are at least two auxiliary deformation grooves 6, which are evenly distributed along the axial direction of the deformation groove 5, and the auxiliary deformation grooves 6 are connected with the deformation groove 5 and are distributed perpendicularly to each other.

[0023] At the same time, the upper end surface of the carrying tray 1 is connected to the lower end surface of the guiding and positioning sleeve 2 and forms an integrated structure. The inner diameter of the carrying tray 1 is 30%-90% of the inner diameter of the guiding and positioning sleeve 2. The lower end surface of the carrying tray 1 is provided with at least two elastic sealing rings 7 of annular structure coaxially distributed with the carrying tray 1. The elastic sealing ring 7 is at least 5 mm higher than the upper end surface of the carrying tray 1, and the area of ​​the elastic sealing ring 7 is 50%-90% of the area of ​​the upper end surface of the carrying tray 1.

[0026] like Figure 3 As shown, a method for using a high-strength anchor cable to position a load-bearing tray comprises the following steps:

[0027] The first step is to prefabricate the equipment. First, according to the distribution position and structure of the drilling holes, a bearing tray, a guide positioning sleeve and a support ring that meet the needs of use are selected, and then the bearing tray, the guide positioning sleeve and the support ring are assembled, and the assembled new type of equipment is abutted against the side wall corresponding to the drilling hole through the bearing tray and coaxially distributed with the drilling hole, and the rock wall around the drilling hole is sealed by the elastic sealing ring of the bearing tray, and the drilling hole is sealed and prefabricated by the elastic sealing plate;

[0028] The second step is anchor cable positioning. After completing the second step, the anchor cable is embedded into the support ring and passes through the support ring, the guide positioning sleeve and the elastic sealing plate in the guide positioning sleeve in sequence along the axis of the support ring, and then embedded into the borehole and positioned. After completing the positioning of the drill rod, the anchor cable is connected to the support ring and the rock wall through the positioning mechanism. When positioning the anchor cable support, the positioning force of the positioning mechanism is transmitted through the guide positioning sleeve and the support ring and then directly transmitted to the elastic sealing ring and the elastic sealing plate of the supporting tray, thereby increasing the pressure between the elastic sealing ring and the elastic sealing plate and the rock wall, thereby further improving the sealing ability of the borehole while improving the stability of the anchor cable positioning, and thus completing the anchor cable positioning.

[0030] At the same time, when the anchor cable structure is subjected to external force impact due to external force impact and geological deformation, the structure of the present invention is first positioned by the structural strength of the bearing tray, the guide positioning sleeve and the support ring. The present invention can further improve the overall structural strength of the present invention through the reinforcement groove, improve the ability to resist deformation external force, and improve the operation stability; then when the external force is too large, the reinforcement groove set on the guide positioning sleeve and the deformation groove at the bottom of the reinforcement groove will undergo elastic deformation, and the interference and influence of the external force on the present invention will be eliminated through the elastic deformation, thereby improving the stability and reliability of the anchor cable positioning of the present invention.

[0031] The present invention has a simple structure, is flexible and convenient to use, and has good versatility. On the one hand, it can effectively meet the needs of anchor cable structure installation and positioning and drilling and plugging operations on working surfaces with different structures; on the other hand, it has good structural strength and elastic deformation capacity, thereby greatly improving the anchor cable positioning stability and resistance to external force impact.
