Description

Technical Field

[0001] This utility model relates to the field of drilling technology, and in particular to a horizontal mast drilling device. Background Technology

[0002] In fields such as geotechnical engineering, tunnel construction, and underground pipeline laying, horizontal drilling is a crucial process. Its quality and efficiency directly affect the progress and safety of the entire project. Currently, there are many types of horizontal drilling rigs on the market, but they still have many shortcomings in practical applications.

[0003] The hydraulic control system of most drilling rigs has complex pipeline connections, making assembly and maintenance inconvenient. When it is necessary to repair or replace the various actuators of the drilling rig, the disassembly and reconnection of the pipelines takes a long time, which greatly reduces the operation and maintenance efficiency of the equipment. At the same time, it is inconvenient to carry out construction operations in confined spaces such as tunnels. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies that make it inconvenient to complete construction work in confined spaces such as tunnels, and to propose a horizontal mast drilling rig device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A horizontal mast drilling rig includes a platform, with outrigger cylinder assemblies welded and fixed at each of the four corners of the platform. The four outrigger cylinder assemblies are used to adjust the height of the platform. At least two connecting plates are welded and fixed to the top of the platform. A mast is fixed to the top of the two connecting plates by bolts. A support plate assembly is provided on the upper side of the mast. A set of sliding parts is provided between the support plate assembly and the mast. The sliding parts are used to allow the support plate assembly to slide smoothly at the top of the mast. The mast is used to drive the support plate assembly to slide. A power head assembly is threadedly fixed to the pallet assembly. The output shaft of the power head assembly is fixed to a drill rod assembly for drilling via a coupling. The mast is equipped with a clamping device for supporting and limiting the drill rod assembly. The platform is equipped with a valve group, which is used to control the flow of oil pipes in the mast, power head assembly, and four outrigger cylinder assemblies. The platform is also fixed with a quick-connect assembly, which has multiple quick-connect pipes at both ends. The quick-connect pipes on both sides are connected. One quick-connect pipe is connected to the oil pipes in the mast, power head assembly, and four outrigger cylinder assemblies, respectively, while the other quick-connect pipe is connected to the oil pipes of the main unit.

[0006] In one possible design, the clamping device includes a bracket bolted to a mast, within which four hydraulic cylinders are bolted and uniformly distributed in a ring. Each of the four hydraulic cylinders has a guide block fixed to its output end, and a receiving gap is formed between the four guide blocks. The drill pipe assembly is located within the receiving gap.

[0007] In one possible design, the oil pipes of all four hydraulic cylinders are connected to quick-connect fittings on one side.

[0008] In one possible design, the bottom ends of the output shafts of the four outrigger cylinder assemblies are all fixed with support plates.

[0009] In one possible design, the bottom of each of the four support plates is fixed with a rubber anti-slip pad.

[0010] In one possible design, the sliding part includes two sets of roller rails fixed to the surface of the mast, and multiple sets of roller sliders are fixed inside the pallet assembly, with the multiple sets of roller sliders slidingly engaging with the two sets of roller rails respectively.

[0011] Beneficial effects: In this utility model, the horizontal mast drilling rig device can flexibly adjust the platform height by setting out the outrigger cylinder assemblies at the four corners of the platform to adapt to the operation requirements of different terrains. With the setting of support plates and rubber anti-slip pads, the contact area and friction with the ground are effectively increased, which improves the overall support stability of the device, avoids shaking or slipping during operation, and ensures operation safety. In this utility model, the horizontal mast drilling rig device adopts a sliding part structure with roller slide rail and roller slider between the mast and the support plate assembly, which effectively reduces the sliding resistance of the support plate assembly, allows the support plate assembly to slide smoothly on the mast, ensures the stability of the drill rod assembly's advance and retraction, and improves the continuity and efficiency of drilling operations. In this invention, quick-connect fittings are provided at both ends of the quick-connect assembly, enabling rapid pipeline connection between each actuator, valve group, and back-end host. This simplifies the pipeline structure, facilitates the assembly and maintenance of the device, reduces the time spent on pipeline disassembly and connection, and improves the equipment's operation and maintenance efficiency. This allows the horizontal mast drilling rig to complete construction operations in confined spaces such as tunnels, which is more efficient than traditional drilling rigs where the horizontal mast drilling rig is separated from the back-end power components. This enables construction operations in underground and height-restricted special areas. Attached Figure Description

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0015] In one embodiment: Refer to Figures 1-3 A horizontal mast drilling rig device, which is used in the field of drilling rig technology, includes a platform 1, a leg cylinder assembly 2, a clamping device 3, a connecting plate 4, a drill rod assembly 5, a power head assembly 6, a support plate assembly 7, a mast 8, and a valve group 9.

[0016] Platform 1, serving as the foundation for the entire device, is constructed from high-strength steel to ensure sufficient structural strength to support the weight of each component. Four outrigger cylinder assemblies 2 are welded and fixed to the four corners of platform 1. The synchronized operation of these four cylinder assemblies allows for height adjustment of platform 1, adapting to different terrain conditions. To further enhance stability, support plates are fixed to the bottom of the output shafts of each of the four outrigger cylinder assemblies 2. These support plates utilize a rectangular steel plate structure to increase the contact area with the ground. Rubber anti-slip pads are also fixed to the bottom of each of the four support plates. These pads are fixed to the support plates through a vulcanization process, effectively increasing friction with the ground and preventing slippage during operation.

[0017] At least two connecting plates 4 are provided, both welded and fixed to the top of the platform 1. Bolt holes are machined at the top of the connecting plates 4. The mast 8 is fixedly connected to the connecting plates 4 by bolts. High-strength bolts are used to ensure the firmness of the connection between the mast 8 and the platform 1. The pallet assembly 7 is set on the upper side of the mast 8. A set of sliding parts is provided between the pallet assembly 7 and the mast 8. The sliding parts enable the pallet assembly 7 to slide smoothly on the top of the mast 8, and the mast 8 can drive the pallet assembly 7 to slide. The sliding parts include two sets of roller slide rails fixed to the surface of the mast 8. Multiple sets of roller sliders are fixed inside the pallet assembly 7. The multiple sets of roller sliders slide in cooperation with the two sets of roller slide rails respectively. The roller slide rails are fixed to the mast 8 by welding, and the roller sliders are fixed to the pallet assembly 7 by bolts. This sliding cooperation method can effectively reduce sliding resistance and ensure the stability and smoothness of the operation of the pallet assembly 7.

[0018] The power head assembly 6 is threaded onto the support plate assembly 7. The power head assembly 6 provides drilling power to the drill rod assembly 5. Its output shaft is fixedly connected to the drill rod assembly 5 via a coupling. The coupling is a rigid coupling to ensure the stability and accuracy of power transmission. The drill rod assembly 5 is used for direct drilling operations. The clamping device 3 is installed on the mast 8 to support and limit the drill rod assembly 5, preventing it from shifting during drilling. The clamping device 3 includes a bracket bolted to the mast 8. The bracket is made of cast steel, and four hydraulic cylinders are bolted inside the bracket. The four hydraulic cylinders are evenly distributed in a ring. Each of the four hydraulic cylinders has a guide block fixed to its output end. The guide blocks are made of wear-resistant alloy, and there is a clearance between the four guide blocks. The drill rod assembly 5 is located within the clearance. During operation, the four hydraulic cylinders act synchronously, driving the guide blocks to clamp inward, thus supporting and limiting the drill rod assembly 5. When the drill rod assembly 5 needs to move, the hydraulic cylinders drive the guide blocks to release outward, without affecting the normal operation of the drill rod assembly 5.

[0019] In another embodiment: Refer to Figures 1-3 A horizontal mast drilling rig device is described, which is applied in the field of drilling rig technology. The structure of this embodiment is basically the same as the previous embodiment, except that: the valve group 9 is fixed on the platform 1 and is used to control the on / off of the oil pipes in the mast 8, the power head assembly 6, and the four outrigger cylinder assemblies 2. Both ends of the quick connector assembly 10 are provided with multiple quick connectors, and the corresponding quick connectors on both sides are kept connected. The quick connector on one side is connected to the oil pipes in the mast 8, the power head assembly 6, and the four outrigger cylinder assemblies 2, and the oil pipes of the four hydraulic cylinders are also connected to the quick connector on that side. The quick connector on the other side is connected to the oil pipe of the main unit. The quick connectors enable quick connection of the oil pipes of each component to the valve group 9, simplifying the pipeline connection structure and facilitating assembly and maintenance. The platform 1 is equipped with the valve group 9 and a PLC controller. The controller is electrically connected to valve group 9 and is used to output control signals to valve group 9. Valve group 9 is used to control the opening and closing of oil pipes in the four hydraulic cylinders of mast 8, power head assembly 6, four outrigger cylinder assemblies 2 and clamping device 3, so as to realize the synchronous or sequential action of each actuator (such as the linkage logic of outrigger leveling → power head start → clamping device clamping limit → pallet assembly advancing drilling). The PLC controller can receive operation instructions through the background host or automatically control the action of each component through preset programs.

[0020] The working process of this device is as follows: Before operation, the main control valve group 9 is used to activate the four outrigger cylinder assemblies 2, adjusting the height of the platform 1 to a suitable position to ensure that the platform 1 is in a horizontal state and the rubber anti-slip pads are in close contact with the ground to achieve stable support of the device. Subsequently, the main control valve group 9 controls the power head assembly 6 to start, which drives the drill rod assembly 5 to rotate. At the same time, the mast 8 is controlled to drive the pallet assembly 7 to slide along the sliding part, pushing the drill rod assembly 5 in the preset direction to perform horizontal drilling. During drilling, the four hydraulic cylinders of the clamping device 3 are controlled by the valve group 9 to activate the guide block to clamp the drill rod assembly 5, supporting and limiting the drill rod assembly 5 to ensure the accuracy of the drilling trajectory. After the operation is completed, the pallet assembly 7 is controlled to drive the drill rod assembly 5 to retract, the power head assembly 6 is turned off, and the outrigger cylinder assemblies 2 are adjusted to lower the platform 1 to complete the operation.

[0021] The accompanying drawings in this application are for illustrative purposes only. The dimensions and shapes of the components shown are not actual limitations but are merely schematic representations. In actual implementation, the components can be reasonably configured and adjusted according to specific needs and actual conditions.

[0022] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
