Description

Technical Field

[0001] This utility model relates to the field of devices for drilling by driving in pipes, and in particular to a rescue drilling rig and its drilling platform and support device. Background Technology

[0002] Even with strict adherence to regulations throughout the entire tunnel excavation process, collapses in excavated sections are unavoidable due to inherently unfavorable geological conditions. For example, when the surrounding rock is weak (such as claystone, shale, or completely weathered rock), or is a fractured zone (fault fracture zone, densely jointed zone) or loose deposit (such as sand and gravel), its self-stabilizing capacity is extremely poor. After excavation, the surrounding rock loses its original stress support, making it prone to loosening and collapse, especially in shallow or biased sections. Furthermore, groundwater action and adverse geological structures can also contribute to tunnel collapses in excavated sections. Therefore, there are currently no effective means to completely prevent tunnel collapses in excavated sections. This problem also exists during the excavation of coal mine roadways.

[0003] Since the collapse occurs in an already excavated section, construction workers working on that section will face the risk of being trapped. To ensure their safety and timely rescue, a lifeline through the collapse point must be established within the critical "golden 48 hours." When the collapse distance in the excavated section is short, the open-cut method can typically be used. However, when the collapse distance is long, the open-cut method is insufficient to meet the time constraints of the rescue window. Current rescue methods typically include shaft drilling, pipe jacking, and large-diameter drilling rig rescue.

[0004] Rescue drilling equipment is used to implement the aforementioned rescue drilling method. Due to its advantages of high mobility, simple deployment conditions, and high drilling efficiency, rescue drilling equipment is an ideal device for tunnel collapse rescue. For example, the applicant's patent application publication number CN117365298A describes a tunnel rescue drilling rig. This tunnel rescue drilling rig belongs to the aforementioned rescue drilling equipment. Its core components include a drilling rig mounting platform and a drilling rig mounted on the platform. The drilling rig mounting platform is a mobile platform, which can be moved as needed at the rescue site using tracks, wheels, and other walking devices, possessing strong mobility and thus allowing for rapid deployment. The drilling rig includes a cylinder power head and a auger power head, both coaxially arranged. In operation, the cylinder power head drives the cylinder, serving as a rescue channel, through the collapse point. The auger power head drives the auger, coaxially arranged with the cylinder, to drill a hole and discharge the excavated soil backward. After the rescue channel is opened, the auger power head pulls out the auger, allowing trapped personnel to pass through the cylinder and escape danger.

[0005] As explained above, since the rescue passage is opened by drilling, and the drilling components include both a cylinder and a auger, significant reaction forces are generated during the drilling process. Since the drilling rig platform is a mobile platform, a backing device must be installed to resist these reaction forces. For example, the applicant's patent application describes the structure of the backing device (referred to as a stop-retreat device in the patent), which includes a ground-supporting assembly hinged to the rear end of the drilling rig platform frame. This ground-supporting assembly includes support plates spaced apart on the left and right sides and a crossbeam connecting the two support plates. A tensioning cylinder is installed between the ground-supporting assembly and the frame. When the equipment is not in operation, the tensioning cylinder can lift the ground-supporting assembly off the ground. When the equipment is in operation, the tensioning cylinder can press the crossbeam of the ground-supporting assembly onto the ground to provide the necessary reaction force for the drilling rig. Piling holes are provided on the crossbeam; if necessary, steel piles can be driven into the ground from the crossbeam to improve its stability.

[0006] While the aforementioned support device can provide relatively stable support under normal circumstances, its load-bearing components include a tensioning cylinder. This cylinder requires a complex hydraulic system, which increases equipment cost, occupies space, and hinders miniaturization. More importantly, the stability of the hydraulic system is uncertain when the tensioning cylinder is subjected to significant forces, potentially leading to support failure. Repairing such failures consumes considerable time, and since rescue operations differ from ordinary construction processes, stable and reliable continuous operation is crucial. Therefore, the aforementioned support device clearly cannot meet the requirements for continuous and stable operation of rescue drilling equipment.

[0007] Furthermore, the aforementioned beam and support plate are fixedly connected, meaning their relative angle is fixed. Only when the ground is level can the entire bottom surface of the beam be in contact with the ground. However, when the ground is uneven (e.g., with steps behind the equipment), the contact area between the beam and the ground decreases. This can cause the ground to be unable to withstand the beam's pressure, resulting in the beam being pressed into the ground and the equipment not being reliably supported. When driving steel piles, the portion of the pile located between the ground and the beam may be bent. If this occurs, it will also lead to the failure of the rear support device.

Adjacent rod segments are connected by a pin, and at least one of them has two or more pin holes along its length that cooperate with the pin.

[0037] The features and performance of this utility model will be further described in detail below with reference to specific embodiments.

[0038] As is well known, a hydraulic cylinder achieves linear motion by driving a piston rod with pressurized fluid. Its core components include the cylinder barrel, piston, seals, and directional valve. When hydraulic oil enters the cylinder chamber, the hydraulic pressure pushes the piston to move. Single-acting cylinders rely on external forces (such as springs) to retract, while double-acting cylinders achieve bidirectional motion by controlling the flow of oil through a directional valve. Based on its hydraulic drive principle, the supporting system needs to include a complete hydraulic system consisting of a hydraulic pump providing power, an oil tank storing oil, and hydraulic valve groups for regulating flow rate and pressure. Due to the large number of components and the complexity of the supporting system, a failure in any part can cause the hydraulic cylinder to stop and lose its supporting function.

[0039] Furthermore, when the hydraulic cylinder or its associated hydraulic system fails, there are many potential points of failure, requiring thorough troubleshooting and subsequent repairs. Therefore, for rescue drilling rigs, which have strict requirements regarding rescue time windows, using hydraulic cylinders as support rods for the backrest device is not the most ideal solution. To address the aforementioned issues, improvements to the hydraulic system (such as backup systems or optimized hydraulic circuits) can be implemented. However, this approach significantly increases the cost of the backrest device and results in it occupying excessive space on the drilling rig's platform. Moreover, since backrest device failure is a low-probability event, improving the hydraulic system would be a considerable waste.

[0040] In contrast, the purely mechanical telescopic rod connected by a pin has a simpler structure and can switch between the working and retracted states of the support device (the retracted state refers to the device being folded up when not in use or when the rescue drilling rig is being moved), while also providing stable and reliable support. Due to its simple structure and the visibility of all components, even in the event of a malfunction, the fault can be quickly identified, and the pin, being a vulnerable part, can be quickly replaced. This allows for effective and cost-efficient operation of the rescue drilling rig.

[0041] This invention is based on the concept of simplifying the structure of the backrest device, reducing the cost of the backrest device, and meeting the requirements for rapid deployment of the backrest device. By redesigning the backrest device, the invention uses a purely mechanical telescopic support rod to replace the hydraulic cylinder support rod in the existing backrest device, and proposes the technical solutions for the backrest device, drilling rig mounting platform, and rescue drilling rig equipment of this invention.

[0042] Based on the above inventive concept, the following will describe in detail the specific embodiments of the rear-mounted device of this utility model with reference to the accompanying drawings.

[0043] like Figure 1-5 As shown, the support device of this utility model includes a ground support component 1 and a support rod assembly connected to the ground support component 1. As the name suggests, the ground support component 1 is a component used to support the ground firmly. In use, the ground support component 1 rests on the ground and presses against it, thereby offsetting the reaction force generated during the drilling process of the rescue drilling equipment. In other words, the ground support component 1 acts as a "foot," providing support from the ground and ensuring the stable operation of the rescue drilling equipment. In practical applications, the ground support component 1 can adopt structural forms such as a floor support, a beam, or a frame structure, as long as a certain ground contact area is ensured to prevent it from being pressed into the ground. Of course, considering that the size of the support device itself should not be too large, and the difficulty of processing, the ground support component 1 is preferably a plate-shaped ground support component or a beam structure with a regular shape (such as a circle or rectangle).

[0044] If we consider the ground support 1 as the "feet," then the support rod assembly acts as the "legs." The support rod assembly connects to the ground support 1 on one hand, and also has a connection structure for connecting to the frame 2 of the drilling rig mounting platform on the other. In use, it connects to the frame 2 of the drilling rig mounting platform via the connection structure, thus providing support between the drilling rig mounting platform and the ground support 1. To ensure the stability of the support, the support rod assembly is designed to include an upper support rod 3 and a lower support rod 4.

[0045] Since the support device needs to be lifted off the ground in scenarios such as the movement of rescue drilling equipment, it needs to be retractable. In some cases, due to the limitations of the rescue drilling equipment's workplace, such as steps, slopes, or depressions in the ground behind the equipment, the ground support 1 needs to be able to stably support itself on the ground at different heights. Therefore, the support rod assembly should also have the function of adjusting the height of the ground support. To meet the above usage requirements, at least one of the upper support rod 3 and the lower support rod 4 of the support rod assembly is set as a telescopic support rod, so that the length can be adjusted in a telescopic manner and locked at a specific length.

[0046] To avoid the high risk of failure caused by the introduction of electrical or hydraulic controls, the telescopic support rod in the rear-mounted device of this invention employs a structure in which multiple rod segments 5 are connected by pins 6. Adjacent rod segments 5 overlap along their length and are each provided with pin holes. At least one segment has multiple pin holes arranged along the length of the rod segment 5. By changing the insertion position of the pins 6, i.e., changing the pin holes that mate with the pins 6, the length of the telescopic support rod can be adjusted and locked at that length. The term "multiple segments" can refer to two, three, or more segments. When using a structure with three or more segments, adjacent rod segments 5 can all be connected using the aforementioned pin hole and pin 6 connection structure. This should be understood by those skilled in the art and will not be elaborated upon here.

[0047] As a preferred embodiment, such as Figure 1-3 As shown, the telescopic strut comprises two segments 5, one of which is hollow, and the other is inserted into the hollow segment, thus forming a plug-in fit structure between the two segments. Multiple pin holes 7 are provided on the hollow segment, spaced apart along the length of the segment. A pin 6 can engage with any of these pin holes, thereby changing the overlap length of the two segments 5 and adjusting the length of the telescopic strut. The purpose of using the pin 6 is to allow for quick insertion and removal, enabling rapid adjustment and disassembly of the telescopic strut's length.

[0048] Although the telescopic struts in the above embodiments employ a plug-in fitting structure between adjacent segments 5, those skilled in the art should understand that this structure is not unique. For example, in other embodiments, connecting plates that can fit together can be provided between the adjacent ends of two adjacent segments 5. The connecting plates extend along the length of their respective segments and are parallel to each other. In this case, when the pins extend in the left-right direction, at least two pins should be used to connect the adjacent segments to avoid relative rotation between the two segments. Furthermore, in other embodiments, adjacent segments can also be connected using angle steel, U-shaped channel steel, or other connecting structures, which should be understood by those skilled in the art.

[0049] As mentioned earlier, the support device needs to be folded and stowed away. Therefore, the connection between the support rod assembly and the drilling rig mounting platform should allow the support rod assembly to tilt and swing at the end connected to the ground support 1 after connection. To meet this requirement, the connection structure on the support rod assembly for connecting to the drilling rig mounting platform is a hinged structure. Figure 1-3 As shown, in a preferred embodiment, the connecting structure specifically adopts a hinge seat 8. During use, the hinge seat 8 can be fixedly connected to the drilling rig mounting platform using quick-release fasteners such as bolts. The upper support rod 3 and lower support rod 4 of the support rod assembly are respectively hinged to the corresponding hinge seat 8. Of course, in other embodiments, when the drilling rig mounting platform has its own hinge seat, the connecting structure only needs to be a hinge joint that can mate with the hinge seat. Specifically, this hinge joint can be a hinge plate (when the hinge seat has a hinge fork) or a fork (when the hinge seat has a hinge plate). The advantage of connecting the support rod assembly to the drilling rig mounting platform using bolts and other fasteners is that the backrest device can be quickly removed when it is not needed.

[0050] When facing uneven terrain in the working environment of a rescue drilling rig, it is necessary to ensure the ground contact area between the ground support 1 and the ground to prevent it from being pressed into the ground due to excessive force. When the upper support rod 3 and the lower support rod 4 are connected to the ground support 1 to form a four-bar linkage, it is difficult to meet the above requirements and ensure stability. Therefore, in a preferred embodiment of the backing device of this utility model, both the upper support rod 3 and the lower support rod 4 are hinged to the ground support 1, and the hinge axes of the two are collinear with those of the ground support 1. This allows the upper support rod 3 and the lower support rod 4 to form a triangular structure after being connected to the ground support 1 and the drilling rig mounting platform, respectively. This provides better stability and allows the ground support 1 to automatically adapt to changes in terrain and maintain full contact with the ground.

[0051] Based on the structure described above, the hinge between the upper support rod 3 and the lower support rod 4 and the ground support member 1 can be made using the same pin 9. In a preferred embodiment, by making the pin 9 a pluggable pin, the upper support rod 3 and the lower support rod 4 can be quickly disassembled and assembled relative to the ground support member 1, so as to facilitate the storage of the backrest device when not in use.

[0052] Of course, in other embodiments, for example, if one of the upper support rod 3 and the lower support rod 4 is fixed to the ground support member 1, and the other of the upper support rod 3 and the lower support rod 4 is hinged to the ground support member 1, the requirements for stable support and support at different heights can also be met. However, in this case, the ground support member may not be able to fully contact the ground, and the contact area with the ground is small. In this case, it is necessary to reinforce the ground behind the rescue drilling equipment that cooperates with the ground support member, such as by laying steel plates, to prevent the ground support member from being pressed into the ground.

[0053] As a preferred embodiment, such as Figure 3 As shown, the ground support 1 is configured as a crossbeam extending in the left-right direction, with support rod assemblies at both ends. The advantage of using a crossbeam for the ground support is that it ensures sufficient contact area between the support and the ground, and provides space for its fixation relative to the ground. For example, in a preferred embodiment, the crossbeam has ground stake holes 10, which can be used with ground stakes to further ensure the relative fixation between the ground support and the ground, enabling it to provide a sufficiently large drilling reaction force. As mentioned earlier, the ground support can also adopt a plate structure. In this case, each ground support 1 is equipped with a support rod assembly, and the two support rod assemblies and the two ground supports together constitute a backing device.

[0054] The specific implementation method of the drilling rig mounting platform of this utility model is as follows: like Figure 1-5 As shown, the drilling rig mounting platform of this utility model includes a frame 2, which supports the drilling rig. A traveling device 11 is installed on the frame 2. In order to maintain the stability of the rescue drilling equipment during operation, a rear support device is provided at the rear end of the frame 2. The rear support device is the rear support device of this utility model. Regarding its structure and working principle, since the specific implementation of the rear support device of this utility model has been described in detail, it will not be repeated here.

[0055] In a preferred embodiment of the drilling rig mounting platform of this utility model, such as Figure 1-3 As shown, the upper support rod 3 is hinged to the rear side of the frame 2, and the lower support rod 4 is hinged to the lower side of the frame 2. This is because the frame 2 has a limited thickness in the vertical direction. This arrangement elongates the sides of the triangle formed between the connection points of the upper support rod 3 and the frame 2 and the lower support rod 4 and the frame 2, thus improving its stability. Furthermore, as a preferred embodiment, in the horizontal direction, the hinge point between the upper support rod 3 and the frame 2 is located outside the hinge point between the lower support rod 4 and the frame 2. This is to facilitate the connection between the upper support rod 3, the lower support rod 4, and the frame 2 when the upper support rod 3 and the lower support rod 4 are not coplanar.

[0056] The specific implementation method of the rescue drilling equipment of this utility model is as follows: like Figure 1-5As shown, the rescue drilling equipment of this utility model includes a drilling rig mounting platform, on which a drilling rig is mounted. The drilling rig mounting platform is the specific platform of this utility model, and its structure and working principle have been described in detail in the specific embodiments of this utility model, therefore they will not be repeated here. The drilling rig includes a coaxially arranged cylinder power head 12 and a auger power head 13. Both the cylinder power head 12 and the auger power head 13 are mounted on the drilling rig mounting platform via guide rails, allowing them to reciprocate back and forth. In use, the cylinder power head 12 drives the cylinder 14 to rotate and move forward, passing through the collapse point and serving as a rescue passage. Furthermore, the auger power head 13 drives the auger 15, coaxially arranged with the cylinder 14, to drill a hole and discharge the excavated soil backward. After the rescue passage is opened, the auger power head 13 pulls out the auger 15, allowing trapped personnel to pass through the cylinder and escape danger.

[0057] Since the cylinder 14 and the auger 15 are connected in sections during use, in order to achieve automated or at least semi-automated operation of the drilling rig, a lifting device 16 and a pipe clamping device 17 are also provided on the drilling rig mounting platform. This structure is prior art, for example, the relevant content is described in the specification of the applicant's patent application with publication number CN117365298A, so it will not be described again here.

[0058] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. The patent protection scope of the present utility model shall be determined by the claims. Similarly, any equivalent structural changes made based on the description and drawings of the present utility model shall also be included within the protection scope of the present utility model.
