Description

Technical Field

[0001] The utility model relates to the technical field of drilling rigs, in particular to an auxiliary supporting device for horizontal drilling of a drilling rig. Background Art

[0002] In current drilling technology, handheld drills are widely used in various construction and maintenance tasks, especially in scenarios where horizontal drilling is required. During horizontal drilling, due to gravity and the reaction force of drilling, it is difficult for the operator to maintain the horizontal position of the drill, which can easily cause the drill hole to deviate, thus affecting the accuracy and efficiency of drilling.

[0003] To solve these problems, the introduction of auxiliary support devices is particularly important. The auxiliary support device can effectively share the weight of the handheld drill rig, reducing the burden on the operator. At the same time, through the support and guidance mechanism, it improves the stability of the drill rig during the horizontal drilling process. By placing the drill rig on the auxiliary support platform, the operator can more easily control the movement of the drill rig, thereby achieving more accurate drilling.

[0004] However, as the drilling rig continues to approach the drilling point on the auxiliary support platform, uneven pressure may be generated on the front and rear centers of the platform due to the weight distribution and movement of the drilling rig. This uneven distribution of pressure may cause instability of the support platform, thereby affecting the positioning of the drilling rig and may even cause the borehole to deviate. Utility Model Content

[0005] The utility model aims to solve one of the technical problems in the related art at least to a certain extent.

[0006] To this end, the purpose of the present invention is to propose an auxiliary support device for horizontal drilling of a drilling rig, which can introduce a counterweight structure. When the drilling rig continues to approach the drilling point, the counterweight structure will correspondingly move away from the drilling point, thereby always keeping the weight of the auxiliary support platform uniform in front and behind, thereby solving the problem that uneven pressure distribution may cause instability of the support platform, thereby affecting the positioning of the drilling rig and even causing the deviation of the drill hole.

[0007] To achieve the above-mentioned purpose, the utility model proposes an auxiliary support device for horizontal drilling of a drilling rig, comprising a mobile base, a support frame, an assembly top plate, a drive assembly, a mobile platform, an assembly seat and a counterweight adjustment assembly, wherein the support frame is fixedly connected to the top of the mobile base, the assembly top plate is fixedly connected to the top of the support frame, a guide groove is provided on the top of the assembly top plate, the drive assembly is installed in the guide groove, and drives the mobile platform to move on the top of the assembly top plate; the assembly seat is fixedly connected to the top of the mobile platform, and the counterweight adjustment assembly is installed on the top of the mobile base and connected to the bottom of the mobile platform.

[0008] The auxiliary support device for horizontal drilling of a drilling rig of the present invention can drive the mobile platform to move its position in the guide groove by starting the driving assembly. When the mobile platform is moving, it synchronously drives the handheld drill on the assembly seat to move, and the drill bit of the handheld drill can continuously approach the drilling point. When the mobile platform continuously approaches the drilling point, the moving part in the counterweight adjustment assembly can be synchronously moved in the opposite direction, so as to always keep the center of the overall structure stable, thereby solving the problem that uneven pressure distribution may cause instability of the support platform, thereby affecting the positioning of the drilling rig and even causing deviation of the drill hole.
