Anchor net support structure is mainly suitable for surrounding rock with poor stability and instability, medium expansive soft surrounding rock, surrounding rock with low strength, easy weathering and chipping, low self-stabilization ability and short self-stabilization time, poor bonding performance between shotcrete and surrounding rock, large bending and shear stress on the shotcrete layer, surrounding rock that is easy to crack, and tunnels with large deformation and displacement of surrounding rock, large plastic pressure and long service life, especially in mines. It is necessary to build a structurally stable anchor net support structure to ensure the safety of personnel in the mine.

[0003] When mining coal underground, the mine needs to be reinforced. The existing reinforcement method is to use anchor nets for fixing. Since the anchor net is a kind of protective equipment made of iron wire or steel wire woven into a mesh, in actual application, it is necessary to adjust the height of the top according to the internal height. However, now they are all one-time fixed structures. When the fixation is completed, it is necessary to adjust the height, and the parts need to be remade. The manufactured parts must be used in conjunction with the fixed support structure to adjust the height, which increases the installation cost. At the same time, when the existing support structure is used to fix the anchor net, the anchor net cannot be fixed firmly on the wall, which easily causes the anchor net to move or shake.

The prestressed anchor rod 5 passes through the second anchor net 26 and extends to the outside of the side frame 2. At the same time, a plurality of mounting grooves 51 are provided on the outside of the prestressed anchor rod 5 along its axial direction, and an elastic baffle 52 is connected to the mounting groove 51. Through the cooperation between the elastic baffle 52 and the prestressed anchor rod 5, the resistance between the prestressed anchor rod 5 and the wall is increased, and the prestressed anchor rod 5 is prevented from falling off from the drilled hole, thereby enhancing the stability of the side frame 2 and making the anchor net more secure.

[0036] In actual application, a support structure for an anchor net as described in the utility model is adopted. First, a hole is drilled in advance on the wall in the mine, and then the prestressed anchor rod 5 is inserted into the drilled hole. Finally, the second threaded drill rod 82 is screwed into the prestressed anchor rod 5, so as to achieve the purpose of fixing the side frame 2 on the ground. At the same time, the first threaded drill rod 81 is used to fix the anchor grid 1 on the top of the mine first, and then the adjustment mechanism 7 is used to adjust the connecting plate 3 to move toward the anchor grid 1, and then the connecting angle code 4 is used to connect the connecting plate 3 to the anchor grid 1, and finally the connecting bolts 6 are used to fix the side frame 2 and the connecting plate 3 to complete the installation and fixation. Since a first threaded drill rod 81 is installed in the anchor grid 1 and a prestressed anchor rod 5 is provided in the side frame 2, the first threaded drill rod 81 and the prestressed anchor rod 5 can play a certain fixing role on the anchor net, avoiding displacement or shaking of the anchor net after installation, and the prestressed anchor rod 5 inserted into the mine wall can enhance the stability of the side frame 2. In addition, since an elastic baffle 52 is provided on the outer side of the prestressed anchor rod 5, the elastic baffle 52 cooperates with the prestressed anchor rod 5 to increase the resistance between the prestressed anchor rod 5 and the wall, thereby preventing the prestressed anchor rod 5 from falling off from the drill hole, thereby enhancing the stability of the side frame 2 and making the anchor net more securely fixed.

[0037] A support structure for an anchor net according to the utility model is adopted, wherein the rotation process between the forward and reverse screw rods 74 and the slider 31 is the same as the principle of the wrench in the prior art, and the adjustment mechanism 7 can adopt a hydraulic component in addition to the electric component and the pneumatic component, and the connection plate 3 can also be adjusted by configuring a hydraulic cylinder. Since the variable frequency motor in the electric component, the pneumatic motor in the pneumatic component, and the hydraulic cylinder in the hydraulic component are all commonly used power equipment in the prior art, as long as the use requirements are met, no detailed description is given.

[0038] It can be seen that the support structure described in the utility model is not only convenient for adjustment, but also can fix the anchor net to prevent the anchor net from displacement or shaking, thereby reducing the installation cost.

A supporting structure for an anchor net according to claim 4, characterized in that: The pneumatic motor is a forward and reverse variable speed motor, and is any one of a vane pneumatic motor, a piston pneumatic motor or a gear pneumatic motor. A protective cover (24) is provided in the support plate (23), and the pneumatic motor is arranged in the protective cover (24). A start button for controlling the pneumatic motor is provided on the front of the protective cover (24), and the start button is connected to the pneumatic motor.

6. A supporting structure for an anchor net according to claim 1, characterized in that: Two strip-shaped waist-shaped holes (61) are provided, and the two strip-shaped waist-shaped holes (61) are symmetrically arranged on both sides of the slider (31). The side frame body (2) and the connecting plate (3) are connected by connecting bolts (6) passing through corresponding strip-shaped waist-shaped holes (61).

7. A supporting structure for an anchor net according to claim 6, characterized in that: A baffle plate (25) is also provided in the side frame body (2), and the baffle plate (25) is located at the top of the slide groove (21). A plurality of through holes are provided in the side frame body (2), and the plurality of through holes are symmetrically arranged on the outside of the slide groove (21). A prestressed anchor rod (5) is provided in each through hole, and a second anchor net (26) is also connected to the outside of the side frame body (2), and the prestressed anchor rod (5) passes through the second anchor net (26) and extends to the outside of the side frame body (2); the second anchor net (26) is a high-strength flexible net, and the material of the high-strength flexible net is an organic chemical fiber material or a metal material.

8. A supporting structure for an anchor net according to claim 7, characterized in that: A plurality of installation grooves (51) are provided on the outer side of the prestressed anchor rod (5) along its axial direction, and elastic blocking sheets (52) are connected to the installation grooves (51).

9. A supporting structure for an anchor net according to claim 1, characterized in that: The anchor grid frame (1) comprises a bracket (11) and a first anchor net (12) arranged on the bracket (11); the connection angle code (4) is provided with a connection screw; screw holes matching the connection screws are respectively provided in the connection plate (3) and the bracket (11); the connection angle code (4) realizes a detachable connection between the connection plate (3) and the bracket (11) in the anchor grid frame (1) through the cooperation of the connection screws and the screw holes; the first anchor net (12) is a high-strength flexible net, and the material of the high-strength flexible net is an organic chemical fiber material or a metal material.
