Description

Technical Field

[0001] This utility model relates to the technical field of hydraulic supports, specifically to a hydraulic support for a mining drilling rig. Background Technology

[0002] In the field of mineral exploration, hydraulic supports are key components supporting drilling rigs. Traditional exploration drilling rig hydraulic supports mostly adopt a structure where vertical hydraulic cylinders directly lift and support the equipment. The support force is provided by the extension of the hydraulic cylinders, and its stability largely depends on the pressure holding performance of the hydraulic system and the friction between the support base and the ground.

[0003] However, in actual exploration operations, the ground surface is often rugged or the soil is soft, and the drilling rig generates severe vibrations and impacts during operation. This makes traditional supports prone to slight subsidence or slippage, affecting drilling accuracy and even threatening operational safety. Current technologies typically improve stability by increasing the base area of ​​the support or the number of hydraulic cylinders, but this results in a bulky and heavy equipment structure, making it difficult to move and operate in complex terrain. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a hydraulic support for a prospecting drilling rig, which can solve the following problems:

[0005] Traditional supports suffer from problems such as "easy sinking, easy slippage, and insufficient stability" on complex terrain.

[0006] To solve the above-mentioned technical problems, the present invention proposes the following technical solution:

[0007] A hydraulic support for a mining drilling rig includes a support top plate, a connecting frame, a supporting base plate, and a hydraulic actuator disposed at the bottom corner of the connecting frame. The hydraulic actuator includes a basic lifting unit and an auxiliary reinforcement unit. The basic lifting unit includes a vertically arranged first hydraulic rod, the bottom end of which is drivenly connected to the supporting base plate. The auxiliary reinforcement unit includes a support arm, an adjusting frame, a second hydraulic rod, a connecting seat, and a pressure plate. The support arm is fixed to the bottom of the connecting frame. The first hydraulic rod is housed in the inner space of the support arm. The middle part of the adjusting frame is hinged to the bottom end of the support arm. The two ends of the second hydraulic rod are respectively hinged to the inner side of the support arm and the inner end of the adjusting frame. The top end of the connecting seat is hinged to the bottom of the inner end of the adjusting frame, and a pressure plate is fixedly connected to its bottom end. The pressure plate is suspended above the supporting base plate, and the contact surface between the pressure plate and the supporting base plate has an anti-slip structure.

[0008] Furthermore, the anti-slip structure consists of bi-directional serrations formed on the contact surface of the pressure plate.

[0009] Furthermore, the inner end of the adjusting frame that is hinged to the connecting seat is constructed as a downward "Z"-shaped bend structure.

[0010] Furthermore, the "Z"-shaped bend area adopts a large-radius arc transition and is equipped with reinforcing ribs inside.

[0011] Furthermore, the support arm is a frame structure with internal support braces, which form a triangular stability zone between the support braces and the main structure of the support arm.

[0012] Furthermore, the top of the second hydraulic rod is connected to the support arm via a self-aligning spherical bearing.

[0013] Furthermore, the bottom end of the first hydraulic rod is connected to the support base plate via a ball joint assembly.

[0014] Furthermore, the bottom surface of the supporting base plate is composite with a supporting layer.

[0015] As can be seen from the above technical solution, the beneficial effects of this utility model are:

[0016] 1. This utility model provides active reinforcement, significantly improving stability. By driving the adjustment frame with a second hydraulic rod to generate lever motion, the horizontal thrust is efficiently converted into vertical downward pressure between the connecting seat and the pressure plate. This downward pressure, together with the main lifting force of the first hydraulic rod, is equivalent to providing an additional "clamping" force for the supporting base plate. Furthermore, the bidirectional serrations on the contact surface between the pressure plate and the supporting base plate form an anti-slip tenon structure, greatly enhancing the anti-slip and anti-overturning capabilities of the support. It is particularly suitable for harsh ground conditions such as soft and sloping surfaces.

[0017] 2. In this utility model, the entire auxiliary reinforcement mechanism (support arm, adjustment frame, second hydraulic rod, connecting seat and pressure plate) is integrated at the end corner of the top plate of the support, and the first hydraulic rod is vertically set on the open inner side of the support arm. This layout allows the auxiliary reinforcement mechanism and the foundation lifting mechanism to work independently and collaboratively without interfering with each other, thereby enhancing the function without significantly increasing the overall outline of the support.

[0025] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0026] See Figure 1-4 As shown, a hydraulic support for a mining drilling rig includes a rectangular support top plate 1 and a rectangular connecting frame 2 on its bottom surface. Hydraulic components 3 are fixedly connected to the bottom corners of the connecting frame 2. A support base plate 4 is provided at the bottom of the hydraulic components 3. A first hydraulic rod 5 is embedded between the top of the support base plate 4 and the hydraulic components 3.

[0027] The hydraulic assembly 3 includes a support arm 6 and an adjustment frame 8 that is flipped and connected to its bottom end. A second hydraulic rod 7 is movably connected to the inner side of the support frame 6 and the inner end of the adjustment frame 8. A connecting seat 10 is movably connected to the bottom of the inner end of the adjustment frame 8. A pressure plate 9 is fixedly connected to the bottom end of the connecting seat 10. A support layer 11 is fixedly connected to the bottom end of the support base plate 4.

[0028] In this embodiment of the utility model, the connecting frame 2 is specifically configured as a closed rectangular box beam structure. The top surface of the supporting base plate 4 is connected and welded to the first hydraulic rod 5 with a hemispherical bowl-shaped support to facilitate ball joint connection and allow adaptive leveling. The bottom surface of the supporting base plate 4 is machined with cross-shaped anti-slip texture. The piston rod end of the first hydraulic rod 5 is connected to the bowl-shaped support of the supporting base plate 4 through a ball head rod with a locking nut. A corrugated tube protective sleeve is installed on the outside of the cylinder of the first hydraulic rod 5.

[0029] The support arm 6 is vertically arranged in a frame structure with an open inner design. Its top surface is fixedly connected to the bottom corner of the connecting frame 2. The adjustment frame 8 consists of main frame bodies that are longitudinally distributed on both sides of the bottom end of the support arm 6. The outer end of the main frame body (the end away from the second hydraulic rod 7) is fixed by a shaft. The inner end of the main frame body (the end near the second hydraulic rod 7) is simultaneously connected to the bottom end of the second hydraulic rod 7 by a shaft. The support arm 6 frame is provided with supporting diagonal braces, which form multiple triangular stable areas with the main structure. The middle section of the adjustment frame 8 and the bottom end of the support arm 6 are connected by a set of longitudinally embedded shafts. The inner ends of the two sets of main frame bodies that make up the adjustment frame 8 are set downward with a "Z" shaped bend. The "Z" shaped bend area of ​​the adjustment frame 8 is set as a large radius arc transition, and triangular stiffeners are also provided inside.

[0030] The first hydraulic rod 5 is vertically arranged and located inside the support arm 6. A first connecting support is provided at the top of the first hydraulic rod 5 and located inside the support arm 6. The first connecting support is horizontally protruding inside the support arm 6. The bottom end of the first hydraulic rod 5 is fixedly connected to the support base plate 4. The contact surface between the pressure plate 9 and the support base plate 4 is provided with bidirectional serrations, and an anti-slip tenon structure is formed between them. The connecting seat 10 is arranged in an inverted "T" shape and is connected to the bottom of the inner end of the adjusting frame 8 by a shaft. The pressure plate 9 is a rectangular plate and is located above the support base plate 4.

[0031] The top of the second hydraulic rod 7 is equipped with a set of second connecting supports located inside the support arm 6. The top of the second hydraulic rod 7 and the second connecting supports are movably connected by a self-aligning spherical bearing. The pressure plate 4 is set in a trapezoidal shape. The support layer 11 is set as a three-layer composite structure. Its uppermost layer is a rubber layer, which mainly provides shock absorption. The middle layer is a polyurethane layer, and the bottommost layer is a wear-resistant nylon layer with anti-slip pattern. Its whole high-strength adhesive is vulcanized and bonded to the support base plate 4 as a whole.

[0032] The core of this device lies in providing a mechanism that actively reinforces the support of the bracket after the lifting adjustment is completed. This mechanism is composed of an adjusting frame 8, a second hydraulic rod 7, a connecting seat 10, and a pressure plate 9. The second hydraulic rod 7 drives the adjusting frame 8 to generate lever movement, ultimately converting the horizontal thrust into a vertical downward pressure on the support base plate 4, forming an anti-slip locking structure, thereby significantly enhancing the stability and anti-slip capability of the support. To ensure the realization of this core function and improve the reliability of the device, this solution integrates and applies the following mature existing public technologies:

[0033] The basic hydraulic lifting technology, in which the first hydraulic rod 5 and its control system adopt the publicly available hydraulic cylinder drive principle to realize the overall height adjustment and basic support of the support frame, is existing technology;

[0034] Active connection compensation technology: In order to achieve smooth linkage between various moving parts and compensate for installation tolerances, self-aligning spherical bearings and wear-resistant bushings are used at the top of the second hydraulic rod 7, the adjusting frame 8 and various hinge points. These are standard mechanical connection elements and are existing technologies.

[0035] Anti-loosening and locking technology, in order to prevent the connection from loosening in a vibrating environment, uses locking nuts, pins and other anti-loosening components in key connection parts such as ball joints and pins. This is a standard mechanical fastening method and is existing technology.

[0036] Therefore, the existing publicly available technologies and methods mentioned above will not be elaborated upon further.

[0037] The hydraulic support for the prospecting drill rig of this device is an independent and complete support unit. The top plate 1 of the support serves as a universal interface for connecting with the main body of the prospecting drill rig. It can be fastened to the corresponding structure of the drill rig base using conventional connection methods known to those skilled in the art, such as using preset bolt holes, thereby achieving matching installation with various prospecting drill rigs. At the same time, the protection scope and core technical solution of this utility model lie only in the mechanical structure innovation of the hydraulic support itself, especially its unique auxiliary reinforcement mechanism. The specific connection and fixing method between the hydraulic support and the main body of the drill rig belongs to the category of common installation technology in the mechanical field and is not the innovation point of this utility model. Therefore, it will not be described in detail.

[0038] When this device is in use, the first hydraulic rod 5 is activated first, pushing the support base plate 4 to adjust the height of the entire bracket. After the height adjustment is completed, the second hydraulic rod 7 is activated, pushing the inner end of the adjustment frame 8 connected to it to tilt downward, while the outer end of the adjustment frame 8 tilts upward.

[0039] After the adjustment frame 8 is tilted, it drives the connecting seat 10 connected to it to descend, which assists in pressing down the entire support base plate 4 to ensure the support stability of the support base plate 4.

[0040] When the second hydraulic rod 7 pushes one end of the adjustment frame 8 to tilt and adjust, since the first hydraulic rod 5 is vertically located inside the support arm 6, the first hydraulic rod 5 can avoid obstructing the movement adjustment of the second hydraulic rod 7.

[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although the 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. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model, and they should all be covered within the scope of the claims and specification of this utility model.
