Description

Technical Field

[0001] The utility model relates to a full-hydraulic multifunctional drilling rig with an all-terrain adaptive chassis, belonging to the technical field of chassis for full-hydraulic multifunctional drilling rigs. Background Art

[0002] At present, the drilling rigs used in open-pit mines include rotary cutting drills, down-the-hole drills and rotary drills.

[0003] However, the crawler chassis of existing drilling rigs cannot swing at an angle. Therefore, when the drilling rig is traveling on a mountain, when one side of the crawler hits a raised block on the ground and is lifted up for traveling, the other side of the crawler will also be lifted up and suspended, causing the drilling rig to tilt and shake greatly when traveling, making it more difficult for users to operate the drilling rig and posing a safety hazard. In addition, when the drilling rig encounters forward or backward climbing, because the power assembly is fixedly connected to the crawler chassis, the power assembly cannot be lifted up or pressed down, and it is easy to scrape against the slope. In view of the above problems, the utility model proposes a fully hydraulic multifunctional drilling rig with an all-terrain adaptive chassis. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model aims to provide a fully hydraulic multifunctional drilling rig with an all-terrain adaptive chassis to solve the existing problems.

[0005] In order to achieve the above-mentioned purpose, the utility model is realized through the following technical scheme: a fully hydraulic multifunctional drilling rig with an all-terrain adaptive chassis, including a power assembly, and the lower end of the front side of the power assembly is sleeve-hinged with a first walking track assembly through a first articulated shaft core, and the lower end of the rear side of the power assembly is sleeve-hinged with a second walking track assembly through a second articulated shaft core, a first oil cylinder is bidirectionally articulated between the power assembly and the first walking track assembly, and a second oil cylinder is bidirectionally articulated between the power assembly and the second walking track assembly.

[0006] A further improvement is that the front end of the left side of the power assembly is provided with a first support for being hinged to the first walking track assembly, the rear end of the left side of the power assembly is provided with a second support for being hinged to the second walking track assembly, the upper end of the front side of the power assembly is provided with a third support for being hinged to the upper end of the first cylinder, and the upper end of the rear side of the power assembly is provided with a fourth support for being hinged to the upper end of the second cylinder.

[0007] As a further improvement, an axial core hole is provided at the middle upper end of the first walking track assembly, a fifth support hinged to the lower end of the first oil cylinder is provided at the right upper end of the first walking track assembly, and the first walking track assembly has the same structure as the second walking track assembly.

[0008] A further improvement is that the maximum swing angle of the front and rear lifting of the first walking crawler assembly on the power assembly is 7 degrees.

[0009] A further improvement is that the maximum swing angle of the front and rear lifting of the second walking crawler assembly on the power assembly is 7 degrees.

[0010] As a further improvement, the maximum upward swing angle of the power assembly between the first walking crawler assembly and the second walking crawler assembly is 13 degrees, and the maximum downward swing angle of the power assembly between the first walking crawler assembly and the second walking crawler assembly is 7 degrees.

[0011] As a further improvement, the power assembly, the first walking crawler track assembly and the second walking crawler track assembly are prior art, and their structures are not described one by one here.

[0012] A further improvement is that both the first oil cylinder and the second oil cylinder are equipped with built-in pressure sensors, and the pressure sensors are used to automatically replenish oil and adaptively extend and retract when the first walking crawler assembly and the second walking crawler assembly are lifted forward and backward during walking, allowing the oil cylinder to sense pressure changes.

[0013] The beneficial effects of the utility model are:

[0014] The utility model provides a fully hydraulic multifunctional drilling rig with an all-terrain adaptive chassis. An all-terrain adaptive chassis is formed by an articulated design of a first walking crawler assembly, a second walking crawler assembly, a first oil cylinder, a second oil cylinder, a first articulated shaft core, and a second articulated shaft core on a power assembly. The two walking crawler assemblies of the adaptive chassis of the fully hydraulic multifunctional drilling rig can perform a unilateral adaptive swing angle, and the walking crawler assembly on the other side without a swing angle will be close to the ground and will not be in a suspended state, so that the adaptive chassis can perform a unilateral adaptive swing angle after being pressed by a ground bulge during walking, thereby reducing the tilting and shaking amplitude of the adaptive chassis during walking, thereby improving the stability and safety of the fully hydraulic multifunctional drilling rig on the construction site and ensuring the safety of the construction workers. In addition, the power assembly can be lifted up or pressed down at the tail between the two walking crawler assemblies through manual operation of the two oil cylinders, so that when the adaptive chassis moves forward or backward to climb a slope, the tail of the power assembly will not scratch the slope surface.

[0021] In order to make the technical means, creative features, achieved purposes and effects of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] Please refer to Figures 1-6 , a technical solution of a schematic diagram of a full-hydraulic multi-functional drill of a full-terrain adaptive chassis of the present utility model: including a power assembly 1, and the lower end of the front side of the power assembly 1 is sleeved and hinged with a first walking track assembly 2 through a first hinge axis core 6, and the lower end of the rear side of the power assembly 1 is sleeved and hinged with a second walking track assembly 3 through a second hinge axis core 7. A first oil cylinder 4 is bidirectionally hinged between the power assembly 1 and the first walking track assembly 2, and a second oil cylinder 5 is bidirectionally hinged between the power assembly 1 and the second walking track assembly 3. A first support 11 for hinging with the first walking track assembly 2 is arranged at the front end of the left side of the power assembly 1, and a second support 12 for hinging with the second walking track assembly 3 is arranged at the rear end of the left side of the power assembly 1. A third support 13 for hinging with the upper end of the first oil cylinder 4 is arranged at the upper end of the front side of the power assembly 1, and a fourth support 14 for hinging with the upper end of the second oil cylinder 5 is arranged at the upper end of the rear side of the power assembly 1. An axis core hole 21 is opened at the upper end of the middle part of the first walking track assembly 2, and a fifth support 22 for hinging with the lower end of the first oil cylinder 4 is arranged at the upper end of the right side of the first walking track assembly 2. The first walking track assembly 2 and the second walking track assembly 3 have the same structure. The maximum swing angle of the front and rear lift of the first walking track assembly 2 on the power assembly 1 is 7 degrees, and the maximum swing angle of the front and rear lift of the second walking track assembly 3 on the power assembly 1 is 7 degrees. The maximum swing angle of the upward lift of the power assembly 1 between the first walking track assembly 2 and the second walking track assembly 3 is 13 degrees, and the maximum swing angle of the downward pressure of the power assembly 1 between the first walking track assembly 2 and the second walking track assembly 3 is 7 degrees.

[0023] Working principle:

[0024] When the adaptive chassis of the drill rig moves forward on the mountain, if the first traveling track assembly 2 encounters a raised block, the front end of the first traveling track assembly 2 will press on the raised block to self-adapt the swing angle. During this process, due to the self-adaptive swing of the first traveling track assembly 2, the pressure sensor on the first oil cylinder 4 will sense the pressure change and make the first oil cylinder 4 automatically supply oil for telescoping to achieve the balance of the vehicle platform. The second traveling track assembly 3 will still closely follow the ground and will not be lifted up and suspended. (Refer to the appendix Figure 4 ), thus effectively reducing the tilting and swaying during walking. Similarly, the principle of the second traveling track assembly 3 is the same as that of the first traveling track assembly 2.

[0025] When the adaptive chassis moves forward or backward up the slope, when it is visually estimated that the power assembly 1 is likely to touch the slope surface, by manually operating the telescoping of the first oil cylinder 4 and the second oil cylinder 5, the power assembly 1 can be swung up or down at an angle between the two traveling track assemblies. It should be noted that the upward swing angle of the power assembly 1 is applicable to moving backward up the slope, and the downward swing angle of the power assembly 1 is applicable to moving forward up the slope. (Refer to the appendix Figure 5 、 6 ).
