[0002] "Geological exploration" refers to the investigation and research activities of exploring and detecting the geology through various means and methods, determining the appropriate bearing layer, determining the foundation type according to the bearing capacity of the foundation of the bearing layer, and calculating the foundation parameters. In the process of geological exploration, the main special mechanical equipment that drives the drill to drill physical geological data cores, ore cores, rock cuttings, liquid samples, gas samples, etc. from underground is referred to as a drilling machine. When the drilling machine is drilling, due to the large size of the drilling machine and the large reverse force it will receive during operation, hydraulic support devices are usually installed on the front and rear sides of the drilling machine, and the hydraulic cylinder is used to push the grounding plate at the bottom close to the ground to improve the stability of the drilling machine during operation.

[0003] The support devices installed on the front and rear sides of the existing drilling machine can basically meet the use needs: however, during the drilling process, especially for drilling work in the working area with hard soil, the drilling machine is often subjected to a strong reaction force. Relying only on the single grounding plate on the support device, due to the limited contact area between the single grounding plate and the ground, and the lack of anti-tilt components around the grounding plate, it is often not easy to effectively offset the reaction force, resulting in the grounding plate tilting, and then causing the drilling machine to tilt or even flip over, which has certain safety hazards. Based on this, the utility model provides a support device for geological drilling. Utility Model Content

[0004] The technical problem solved by the utility model is that the contact area between the single grounding plate on the support device and the ground is limited, and there is a lack of anti-tilt components around the grounding plate, which often makes it difficult to effectively offset the reaction force, causing the grounding plate to tilt, and then causing the drilling rig to tilt or even flip over, posing certain safety hazards.

[0006] Furthermore, a mounting seat is provided on the other side of the support arm, and a mounting hole is provided on the mounting seat.

[0007] Furthermore, the anti-tilt assembly is provided with three groups, the side wall of the support rod is fixedly connected to the side wall of the connecting seat, and the three groups of the anti-tilt assembly are arranged in a triangular distribution outside the main grounding plate.

[0008] Furthermore, the end of the support rod is provided with a slot matching the adjustment rod, the front end of the support rod is provided with a through hole matching the bolt, and the rod of the adjustment rod is provided with a plurality of adjustment holes matching the bolt at equal intervals.

[0010] Furthermore, the side wall of the hollow block is provided with a reinforcing rib fixedly connected to the side wall of the adjusting rod.

[0011] Beneficial effects of the utility model:

[0012] 1. The triangularly distributed auxiliary grounding plate expands the contact area with the ground, offsets the reaction force of the roll, and the reaction force pushes the auxiliary grounding plate upward, thereby driving the connecting rod and the slide plate to move upward, thereby compressing the spring equipped with the damper.

A spring 15 equipped with a damper is provided between the top wall and the top of the slide plate 12. When the drilling rig is conducting geological drilling and is subjected to a strong reaction force during drilling, the supporting device supports the drilling rig. Once the reaction force is too large and causes the main grounding plate 6 to tilt, the triangularly distributed auxiliary grounding plate 14 expands the contact area with the ground to offset the reaction force of the tilt, and the reaction force will push the auxiliary grounding plate 14 upward, thereby driving the connecting rod 13 and the slide plate 12 to move upward, thereby causing the spring 15 equipped with a damper to be compressed. Under the action of the spring 15 equipped with a damper, vibration is reduced and energy is dissipated, thereby offsetting the reaction force, so as to prevent the main grounding plate 6 from tilting and causing the drilling rig to tilt or even overturn, thereby enhancing the stability of the supporting device and reducing safety hazards.

[0022] According to the attached Figure 2 As shown: a mounting base 16 is provided on the other side of the support arm 1, and a mounting hole 17 is provided on the mounting base 16. The mounting base 16 is installed on the front and rear sides of the drilling rig by screws, so that the supporting device is respectively arranged on the front and rear sides of the drilling rig to realize the supporting work of the drilling rig. How to install it is existing common knowledge and will not be elaborated again.

[0023] According to the attached Figure 1 , 3 As shown: the anti-tilt assembly 7 is provided with three groups, the side wall of the support rod 8 is fixedly connected to the side wall of the connecting seat 5, and the three groups of anti-tilt assemblies 7 are arranged in a triangular distribution on the outside of the main grounding plate 6. The triangular distribution is on the outside of the main grounding plate 6. Considering the stability of the triangular structure, it can effectively offset the reaction force when the main grounding plate 6 tilts, so as to avoid the situation where the drilling rig tilts or even turns over due to the tilt of the main grounding plate 6, thereby enhancing the stability of the support device and reducing safety hazards.

[0024] According to the attached Figure 2 As shown: the end of the support rod 8 is provided with a slot matching the adjustment rod 9, the front end of the support rod 8 is provided with a through hole matching the bolt 10, and the rod of the adjustment rod 9 is equidistantly provided with a plurality of adjustment holes 18 matching the bolt 10. By matching the bolt 10 with the adjustment holes 18 at different positions, the extension length of the adjustment rod 9 can be adjusted, and the distance between the auxiliary grounding plate 14 and the main grounding plate 6 can be adjusted according to the needs of use to prevent the main grounding plate 6 from tilting.

[0025] According to the attached Figure 5 As shown: the two inner side walls of the hollow block 11 are symmetrically provided with slide rails 19 that match the side walls of the slide plate 12, which play a role in limiting the position of the slide plate 12.

[0026] According to the attached Figure 1 As shown: the side wall of the hollow block 11 is provided with a reinforcing rib 20 fixedly connected to the side wall of the adjusting rod 9, which plays a role in strengthening the fixation.

[0027] Principle of the utility model

[0028] When in use, the mounting base 16 is installed on the front and rear sides of the drilling rig by screws, so that the supporting devices are respectively arranged on the front and rear sides of the drilling rig. When the drilling rig is performing geological drilling, the extension length of the adjusting rod 9 is adjusted by matching the bolts 10 with the adjusting holes 18 at different positions, so that the distance between the auxiliary grounding plate 14 and the main grounding plate 6 can be adjusted according to the use needs. By starting the hydraulic cylinder 3 to drive the hydraulic push rod 4 to move downward, the main grounding plate 6 and the auxiliary grounding plate 14 are driven to move downward until they are closely fitted with the ground. When the drilling rig is subjected to a strong reaction force during drilling, the hydraulic cylinder 3 is driven to drive the hydraulic push rod 4 to move downward, so that the main grounding plate 6 and the auxiliary grounding plate 14 are driven to move downward until they are closely fitted with the ground. The supporting device supports it. Once the reaction force is too large to cause the main grounding plate 6 to tilt, the triangularly distributed auxiliary grounding plate 14 will expand the contact area with the ground to offset the reaction force of the tilting, and the reaction force will push the auxiliary grounding plate 14 upward, thereby driving the connecting rod 13 and the slide plate 12 to move upward, thereby causing the spring 15 equipped with a damper to be compressed. Under the action of the spring 15 equipped with a damper, vibration is reduced and energy is dissipated, thereby offsetting the reaction force, so as to prevent the main grounding plate 6 from tilting and causing the drilling rig to tilt or even overturn, thereby enhancing the stability of the support device and reducing safety hazards.

[0029] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
