Description

Technical Field

[0001] The present application relates to the field of tunnel construction, and in particular to an adjustable double-hole locking foot anchor locking member. Background Art

[0002] In construction scenarios such as tunnels and underground projects, anchor bolt locking parts are widely used to support and fix structures to ensure construction safety and stability. For example, anchor bolts buried in the face and steel arch frames built in the tunnel clearance area are fixed by anchor bolt locking parts, and the steel arch frames are usually I-beams, thus building a stable support system. However, due to the complexity and variability of the construction environment, traditional anchor bolt locking parts often cannot meet the installation requirements of anchor bolts with different spacings, and the lack of adjustment flexibility has become a major technical bottleneck.

[0003] At present, there are some adjustable anchor bolt locking parts on the market, which mainly adapt to anchor bolts with different spacings by setting multiple mounting holes or using adjustable connection structures. However, these solutions still have many problems in practical applications, such as limited adjustment range, cumbersome installation operation, and insufficient structural stability. Especially in extreme situations such as large deformation of surrounding rocks, these support parts often cannot provide sufficient support force, posing safety hazards.

[0004] Therefore, how to design an anchor rod locking device that has both flexible adjustment capabilities and can ensure structural stability has become a technical problem that needs to be urgently solved in the current construction field. Utility Model Content

[0005] In order to provide a device that can achieve flexible adjustment and ensure structural stability, the present application provides an adjustable double-hole locking foot anchor rod locking piece.

[0006] The present application provides an adjustable double-hole locking foot anchor rod locking member adopts the following technical solution:

[0007] An adjustable double-hole locking foot anchor rod locking piece, comprising:

[0008] A backing plate body having two waist-shaped mounting holes, wherein the two waist-shaped mounting holes are spaced apart in a first direction, and the hole length direction of the waist-shaped mounting holes is parallel to the first direction; and

[0009] A diagonal brace having a connecting end and a free end, wherein in the first direction, the two waist-shaped mounting holes are both connected to the side away from each other with the diagonal brace; the connecting end of the diagonal brace is directly or indirectly hinged to the pad body, and the free end is used to support the angle between the vertical plate and the outer horizontal plate of the I-beam; the diagonal brace is parallel to the second direction along the rotation axis of the pad body;

[0010] The pad body has an overlapping surface, the waist-shaped mounting hole penetrates the overlapping surface along the third direction, and the diagonal brace is located on a side of the pad body having the overlapping surface.

[0011] By adopting the above technical scheme, the pad body is moved so that the anchor rod applied on the face passes through the waist-shaped mounting hole, and then the locking nut is screwed into the anchor rod to fix the pad body to the I-beam with the locking nut; in the process of moving the pad body, the personnel adaptably adjusts the angle of the diagonal support rod so that when the pad body contacts the I-beam, the diagonal support rod can contact the vertical plate and the outer horizontal plate; by setting the waist-shaped mounting hole, it can adapt to two anchor rods with different spacings, thereby improving the versatility of the product; by setting the diagonal support rod, a triangular structure is formed between the diagonal support rod, the vertical plate and the pad body, and the movable pad is supported by the diagonal support rod, which can effectively prevent the pad body from bending.

[0012] Optionally, the diagonal support rod is a telescopic rod with adjustable length.

[0013] By adopting the above technical solution, since the length of the diagonal support rod is adjustable, during the operation, the pad body can be first fixed to the I-beam, and then the length and angle of the diagonal support rod can be adjusted to make the free end of the diagonal support rod abut against the I-beam, which can adapt to different types of I-beams.

[0014] Optionally, the diagonal brace rod comprises an internally threaded sleeve and a threaded rod, wherein the threaded rod is threadedly engaged with the internally threaded sleeve; either the threaded rod or the internally threaded sleeve is located at the connecting end of the diagonal brace rod, and the other is located at the free end of the diagonal brace rod.

[0015] By adopting the above technical solution, when the length of the diagonal support rod needs to be adjusted, the length of the diagonal support rod can be changed by simply rotating the threaded rod along the internal threaded sleeve, and the threads of the threaded rod and the internal threaded sleeve cooperate so that the diagonal support rod has a self-locking function in the direction of its own rod length. It has a simple structure and high firmness.

[0016] Optionally, the diagonal support rod is ball-hinged to a top support block at a free end.

[0017] By adopting the above technical solution, during the process of adjusting the diagonal support rod and the I-beam to abut against each other, since the abutting surface and the I-beam are ball-jointed, it is convenient for personnel to adjust the position and angle of the top support block.

[0018] Optionally, the top support block has two mutually perpendicular abutment surfaces, and the two abutment surfaces are used to abut against the vertical plate and the outer horizontal plate of the I-beam.

[0019] By adopting the above technical solution, the two abutting surfaces are adjusted to be tightly abutted against the vertical plate and the outer horizontal plate of the I-beam, so that the contact surface between the diagonal bracing rod and the I-beam can be increased.

[0020] Optionally, the pad body includes a main pad and an auxiliary pad, the auxiliary pad is located on one side of the overlap surface of the pad body, the two main pads are spaced apart in the first direction, and the two main pads form a receiving area in the first direction;

[0021] The auxiliary pad is detachably connected to the main pad;

[0022] One end of the auxiliary pad close to the accommodating area is an auxiliary overlapping end. In the first direction, the auxiliary overlapping end is located at one end where the two waist-shaped mounting holes are close to each other.

[0023] By adopting the above technical solution, during installation, the auxiliary pad is overlapped on the I-beam, and the thickening effect of the auxiliary pad can further prevent the pad body from bending.

[0024] Optionally, it further includes a pad locking assembly for fixing the main pad and the auxiliary pad;

[0025] The pad locking assembly includes a through rod, which is inserted through the main pad and the auxiliary pad along a third direction. One end of the through rod is fixedly connected to a blocking plate, and the other end is a threaded end. The threaded end of the through rod is adapted to be connected to a blocking nut, and the pad body is clamped between the blocking nut and the blocking plate.

[0026] By adopting the above technical solution, after the through rod passes through the pad body and is threadedly connected with the blocking nut, the main pad and the auxiliary pad can be fixed by the pad locking assembly. The structure is simple and the locking effect is relatively strong.

[0027] Optionally, the blocking nut is located on a side of the main pad away from the auxiliary pad;

[0028] The backing plate locking assembly also includes an elastic gasket;

[0029] The elastic gasket is sandwiched between the blocking piece and the auxiliary pad;

[0030] The connecting end of the diagonal support rod is rotatably connected to the through rod or the blocking piece.

[0031] By adopting the above technical solution, since the diagonal support rod is connected to the pad locking assembly, and an elastic gasket is provided between the pad locking assembly and the pad body, when the anchor rod and the locking nut pull the pad body to move along the third direction toward the face, the elastic gasket can buffer the pad body and the pad locking assembly, thereby reducing deformation of the pad locking assembly.

[0032] Optionally, the main pad is provided with a first through hole for the through rod to pass through, and the auxiliary pad is provided with a second through hole for the through rod to pass through, and a movable gap is left between the inner walls of the first through hole and the second through hole and the through rod in the aperture direction.

[0033] By adopting the above technical solution, through the cooperation of the first gap and the elastic gasket, more space can be provided for the penetration rod, further reducing the deformation of the pad locking assembly.

[0034] Optionally, a reinforcing plate is protruding from the main pad and is located in the accommodating area; a side of the reinforcing plate away from the main pad is coplanar with a side of the auxiliary pad away from the main pad.

[0035] By adopting the above technical solution and providing a reinforcing plate, the bending of the pad body can be further reduced.

[0036] In summary, the present application includes at least one of the following beneficial technical effects:

[0037] 1. Since the present application adopts a waist-shaped mounting hole design, the anchor rod has an adjustment margin in the hole, thereby being able to adapt to the installation requirements of anchor rods with different spacings.

[0038] 2. In the present invention, the diagonal bracing rods are preferably used to form a triangular structure with the pad body and the I-beam, which significantly improves the stability of the support and effectively prevents the pad from bending or breaking.

[0039] 3. By designing the diagonal bracing rod as a telescopic rod with adjustable length and equipping it with a detachable auxiliary pad, the present invention can flexibly cope with various construction environments, greatly improving its practicality and adaptability.
