Description

Technical Field

[0001] This utility model relates to the field of slope drilling technology, specifically to drilling equipment for anchor cable girder beams on road cut slopes. Background Technology

[0002] The reverse construction method for anchored grid beams on road cut slopes is an effective approach for excavating road cut slopes and constructing reinforcement structures such as anchored grid beams. It shortens the excavation step distance, reduces the construction height, strengthens process connections, and achieves shallow excavation and early reinforcement. It can be adapted to local conditions and utilize general-purpose machinery, effectively solving problems related to poor slope self-stability and collapse during excavation. This significantly reduces the incidence of engineering quality and safety accidents, avoids environmental damage, and has positive implications for environmental protection. During construction, holes need to be drilled in the slope to pre-embed anchors. For longitudinal holes, drilling can proceed downwards under gravity. However, for transverse holes, due to the slope's inclination, conventional support equipment struggles to provide stable support for the drilling rig on the inclined slope, and angle adjustment is difficult, increasing drilling difficulty and potentially leading to axial misalignment of the final drilled holes, which is detrimental to the construction of the anchored grid beams. Utility Model Content

[0003] In view of the shortcomings of the existing technology, this utility model proposes a drilling device for anchor cable grid beams on road cut slopes to solve the above problems.

[0004] The objective of this utility model is achieved through the following technical solution:

[0005] The drilling equipment for anchor cable girder beams on road cut slopes provided by this utility model includes:

[0006] A track slab, on which a drilling rig is slidably mounted, and a support structure is installed in the middle of the bottom side of the track slab;

[0007] A base plate has a hinge seat at the center of its top side, and a rotating block is rotatably mounted on the hinge seat. The rotating block is fixedly connected to the bottom end of the support structure.

[0008] The adjustment mechanism includes two first screws, which are symmetrically arranged on both sides of the support structure and on both sides of the rotating block axis. The top end of the first screw is fixedly connected to the bottom side of the track plate, and the bottom end is threaded with a first sleeve. The bottom end of the first sleeve can abut against the top side of the base plate.

[0009] Furthermore, the support structure includes a second screw and a second sleeve. The top end of the second screw is axially rotatably mounted on the bottom side of the track plate, and the second sleeve is threadedly connected to the bottom end of the second screw. The bottom end of the second sleeve is connected to the rotating block.

[0010] Furthermore, a rubber layer is provided on the top surface of the substrate, and an abutment block is axially rotatably mounted on the bottom end of the first sleeve. The bottom end of the abutment block is a narrow, flat, elongated strip.

[0011] Furthermore, positioning holes are respectively provided on the plate surface on both sides of the rotating block's rotation axis of the substrate.

[0012] Furthermore, an angle disc is provided on one side of the track plate, a suspension line is installed at the center of the angle disc, and a plumb bob is provided at the far end of the suspension line.

[0013] As can be seen from the above technical solution, the drilling equipment for anchor cable beams on road cut slopes provided by this utility model is as follows:

[0014] The base plate is placed on an inclined slope surface. By rotating the rotating block, the tilt angle of the track plate can be adjusted by the support structure, so that the drill bit of the drilling rig is at a lateral drilling angle. Then, by rotating the two first sleeves respectively, the bottom ends of the two first sleeves abut against the top side of the base plate, thus fixing the rotation angle of the base plate and keeping the drilling rig in a stable drilling position. This utility model is easy to adjust. The tilt angle of the base plate based on the track plate can be adjusted by rotating and adjusting the two first sleeves respectively, thereby changing the drilling angle of the drilling rig to suit slopes with different tilt angles. This helps to ensure the accuracy of the drilling angle and improve construction quality. At the same time, the adjustment mechanism can also form an additional support between the track plate and the base plate, improving the stability of the support. Attached Figure Description

[0022] To make the above-mentioned objectives, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0023] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly attached to the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0025] like Figure 1-2 As shown, the drilling equipment for anchor cable grid beams on road cut slopes provided in this embodiment includes a track plate 1, a base plate 2, and an adjustment mechanism 3.

[0026] A drilling rig 11 is slidably mounted on the top of the track plate 1. The sliding direction of the drilling rig 11 is parallel to the axis of its own drill bit. A support structure 12 is installed in the middle of the bottom side of the track plate 1.

[0027] A hinge seat 21 is provided at the top center of the substrate 2. A rotating block 22 is rotatably mounted on the hinge seat 21. The rotating block 22 is fixedly connected to the bottom end of the support structure 12, so that the substrate 2 can rotate based on the rotating block 22, thereby forming different tilt angles between the substrate 2 and the track plate 1.

[0028] The adjustment mechanism 3 includes two first screws 31. The two first screws 31 are symmetrically arranged on both sides of the support structure 12 and located on both sides of the rotation axis of the rotating block 22. The top of the first screw 31 is fixedly connected to the bottom side of the track plate 1 and the bottom end is threaded with a first sleeve 32. The bottom end of the first sleeve 32 can abut against the top side of the base plate 2.

[0029] In practical use, the base plate 2 is placed on an inclined slope surface. By rotating the rotating block 22, the tilt angle of the track plate 1 can be adjusted by the support structure 12, so that the drill bit of the drill rig 11 is at a lateral drilling angle. Then, by rotating the two first sleeves 32 respectively, the bottom ends of the two first sleeves 32 abut against the top side of the base plate 2, thereby fixing the rotation angle of the base plate 2 and keeping the drill rig 11 in a stable drilling position. This utility model is easy to adjust. The tilt of the base plate 2 based on the track plate 1 can be adjusted by rotating and adjusting the two first sleeves 32 respectively, thereby changing the drilling angle of the drill rig 11 to suit slopes with different tilt angles. This also helps to ensure the accuracy of the drilling angle and improve the construction quality. At the same time, the adjustment mechanism 3 can also form an additional support between the track plate 1 and the base plate 2, improving the stability of the support.

[0030] Preferably, the support structure 12 includes a second screw 121 and a second sleeve 122. The top end of the second screw 121 is axially rotatably mounted on the bottom side of the track plate 1, and the second sleeve 122 is threadedly connected to the bottom end of the second screw 121. The bottom end of the second sleeve 122 is connected to the rotating block 22. By rotating the second screw 121, the overall length of the support structure 12 can be adjusted, thereby changing the distance between the track plate 1 and the base plate 2, and making it suitable for different construction heights.

[0031] Furthermore, a rubber layer 23 is provided on the top surface of the substrate 2. The surface of the rubber layer 23 has anti-slip textures. An abutment block 33 is axially rotatably mounted on the bottom end of the first sleeve 32. The bottom end of the abutment block 33 is a narrow, flat, elongated strip. After the two first sleeves 32 are rotated and adjusted, the bottom end of the abutment block 33 can abut against the rubber layer 23 to increase the friction between them and prevent the adjustment mechanism 3 from slipping and breaking under pressure. It should be noted that the abutment block 33 needs to be rotated appropriately so that when the bottom end of the abutment block 33 abuts against the rubber layer 23, the length direction of the bottom end of the abutment block 33 can be parallel to the rotation axis of the rotating block 22. This allows the bottom end of the abutment block 33 to fully contact the rubber layer 23, thereby making the contact position between the abutment block 33 and the rubber layer 23 closer to the center of the abutment block 33, preventing the abutment block 33 from shifting under force, and improving stability.

[0032] Preferably, the substrate 2 is provided with positioning hole sleeves 24 on the plate surface on both sides of the rotation axis of the rotating block 22. The substrate 2 can be temporarily fixed on the slope by drilling holes in the positioning hole sleeves 24 and inserting pins, so that the substrate 2 will not move without human support when the drilling rig 11 is working.

[0033] Preferably, an angle disc 13 is provided on one side of the track plate 1. The angle disc 13 has an angle scale. The 0-degree scale line of the angle disc 13 is perpendicular to the track plate 1. A suspension line 131 is installed at the center of the angle disc 13. A plumb bob 132 is provided at the far end of the suspension line 131. Under the action of gravity, the plumb bob 132 makes the suspension line 131 perpendicular to the horizontal plane. The drilling angle of the drilling rig 11 can be obtained by observing the angle between the suspension line 131 and the 0-degree scale line of the angle disc 13, which facilitates construction.

[0034] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
