[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] The core of the present invention is to provide a tensioning reaction frame with good applicability.

[0038] It should be noted that when an element is referred to as "fixing" another element, it may be directly on the other element or there may also be a centered element. When an element is considered to be "connected" to another element, it may be directly connected to the other element or there may be a centered element at the same time. In the description of the present invention, it should be noted that the orientation or positional relationship indicated by the terms "upper", "lower", "vertical", "horizontal", "inside", "outside", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0039] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0040] In a specific embodiment of the tensioning reaction frame for a coring drill provided by the present invention, the tensioning reaction frame comprises a connecting frame 1 and a supporting component for fixing to a base position. The connecting frame 1 is used to connect to the coring drill propulsion device to withstand the horizontal load of the coring drill during the propulsion or coring process. Figure 2 As shown, a connection seat 1-4 for connecting a coring drill is fixed on the installation side 1-5 of the connection frame 1. Support components are provided on both sides of the connection seat 1-4 of the connection frame 1. Figure 1 and Figure 4 As shown, the support component includes two legs 3, the first end of each leg 3 is hinged to the support base 4 through a first rotating shaft 3-5, and the second end of the leg 3 is hinged to the connecting frame 1 through a second rotating shaft 3-4. The first rotating shaft 3-5 and the second rotating shaft 3-4 are parallel to the installation side 1-5.

[0041] In trenchless construction, the angles of the legs 3 relative to the connecting frame 1 are adjusted, and the support bases 4 are fixed to the ground or other basic positions. The connecting frame 1 is located above the legs 3, and the front side of the connecting frame 1 is the installation side 1-5. Figure 1 As shown, a triangular support structure is formed between the ground and the two legs 3 in the support component. Since the legs 3 and the connecting frame 1 and the legs 3 and the support seat 4 are hingedly connected, the three inner angles of the triangular support structure are adjustable, so that the height of the connecting seat 1-4 is adjustable. The core drilling rig is connected to the mounting seat 1-4, and the tensioning reaction frame provides a strong thrust or pull for the core drilling rig to advance by applying a strong pressure or pull to the base surface.

[0042] This type of tensioning reaction frame can be used in constructions with different construction heights for coring drills. It has good applicability, can be used repeatedly, and works reliably and stably. It is especially suitable for working conditions with high efficiency requirements and long-distance coring construction. Specifically, it can be used for kilometer-long coring drills, expanding the application scope of trenchless technology.

[0043] Furthermore, the length of the leg 3 along the line connecting the first end and the second end is adjustable, so that the height of the reaction frame can be adjusted more conveniently to suit different environments. Figure 1 and Figure 3 As shown, the outrigger 3 includes an outrigger cylinder 3-1, an inner sleeve 3-3 sleeved outside the outrigger cylinder 3-1, and an outer sleeve 3-2 sleeved outside the inner sleeve 3-3, and the inner sleeve 3-3 is slidably connected to the outer sleeve 3-2. One of the piston rod and the cylinder body of the outrigger cylinder 3-1 is connected to the outer sleeve 3-2 to form a first end, and the other is connected to the inner sleeve 3-3 to form a second end. Specifically, the inner sleeve 3-3 is hinged to the outrigger cylinder 3-1 through a first pin 3-6, and the outer sleeve 3-2 is hinged to the outrigger cylinder 3-1 through a second pin 3-7. The outrigger cylinder 3-1 bears an axial load, and during the adjustment process, the inner sleeve 3-3 and the outer sleeve 3-2 realize the telescopic function through the telescopic movement of the outrigger cylinder 3-1.

[0044] The pressure of the outrigger oil cylinder 3-1 is adjustable and can maintain pressure for a long time, so that the tension reaction frame can meet the construction requirements of long distance and high reliability. The height of the reaction frame can be adjusted by the extension and contraction of the outrigger oil cylinder 3-1, and even after the support base 4 is connected to the ground, the height of the connecting frame 1 can be adjusted. The tension reaction frame can be further adapted to different environments and improve construction efficiency.

[0045] Preferably, the outrigger oil cylinder 3-1 is connected to a controller for remotely controlling its extension and retraction, and the oil cylinder pressure can be remotely controlled, so as to more conveniently adjust the height of the mounting frame. In addition, the controller can also automatically identify and control the oil cylinder pressure.

[0046] Preferably, the outer wall of the inner sleeve 3-3 fits with the inner wall of the outer sleeve 3-2, and the radial load is borne by the fit, which can effectively protect the outrigger cylinder 3-1 and prevent the outrigger cylinder 3-1 from being damaged by the radial force. In addition, the inner wall of the inner sleeve 3-3 can be specifically fitted with and slidably connected to the outer wall of the outrigger cylinder 3-1.

[0047] Of course, in other embodiments, the legs 3 may also be other linear drive mechanisms such as linear modules.

[0048] Furthermore, an anti-twist device 5 is connected to the connecting frame 1 to prevent the core drilling rig or the reaction frame from twisting, thereby ensuring the stability of the adjustable tension reaction frame when subjected to a large torque and improving the safety of the equipment.

[0049] Optionally, the connecting frame 1 is further provided with a third rotating shaft 5-3 parallel to the mounting side surface 1-5, and the anti-twist device 5 includes an anti-twist rod 5-1 hinged on the third rotating shaft 5-3. Figure 2 As shown, the anti-twist device 5 includes two anti-twist bars 5-1, which are respectively arranged on both sides of the connecting seat 1-4. The two ends of the anti-twist bar 5-1 are respectively provided with an anti-twist bar pin 5-2 and a third rotating shaft 5-3, and the anti-twist bar 5-1 is hinged to the propulsion device through the anti-twist bar pin 5-2.

[0050] Furthermore, if Figure 2 and Figure 4 As shown, the connecting frame 1 includes a connecting frame body 1-1 and a leg connecting seat 2 fixed to both ends of the connecting frame body 1-1 by bolts 1-3. The connecting seat 1-4 is connected to the connecting frame body 1-1, and the leg 3 is connected to the leg connecting seat 2. The leg connecting seat 2 is composed of a plurality of welded steel plates. The connecting frame body 1-1 is composed of a plurality of welded steel plates. The connecting seat 1-4 is provided with a mounting pin hole, and more specifically, the mounting pin hole is arranged on the ear plate structure in the connecting seat 1-4. The mounting pin hole is provided with a mounting pin shaft 1-2 for articulating the core drilling rig parallel to the mounting side 1-5. The connecting seat 1-4 is specifically composed of at least two ear plates arranged in parallel on the mounting side 1-5. The connecting frame body 1-1, the leg connecting seat 2, the supporting component, the supporting seat 4, and the anti-twist device 5 can be respectively regarded as separate modules. The modular design is adopted, and each component can be quickly replaced, which greatly improves the construction efficiency and economic benefits.

[0051] Furthermore, the support seat 4 includes a support plate 4-1, a support ear plate 4-3 fixed to one side of the support plate 4-1, and a ground anchor bolt 4-2 plugged into the support plate 4-1. The first rotating shaft 3-5 is plugged into the support ear plate 4-3. The support plate 4-1 is used to support the support leg 3, and the support plate 4-1 is connected to the base position through the ground anchor bolt 4-2, so that the adjustable reaction frame can firmly grasp the base to prevent overturning and loosening. At the same time, the ground anchor bolt 4-2 is used to connect the base position, which is convenient for disassembly and assembly, and is convenient for repeated use of the reaction frame.

[0052] With the continuous emergence of difficult pipeline laying or tunnel excavation projects, the existing construction technology is powerless when encountering projects with high excavation efficiency requirements, long distances, field construction, and no receiving wells. The current situation urgently needs a set of equipment that can overcome many conditions, be widely used, and can provide strong thrust and pull at the same time, without special starting site requirements and other factors, and can quickly drill and coring. This kind of equipment requires a reaction frame with high performance and safety indicators that can provide strong thrust and pull at the same time.

[0053] The reaction frame provided by the present invention can provide thrust or pulling force to the propulsion system of the core drilling rig, is suitable for core drilling rigs that require long-distance, fast and reliable construction, and provides a more flexible option for complex geological and tunnel excavation design and construction.

[0054] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0055] The tensioning reaction frame provided by the present invention is introduced in detail above. Specific examples are used in this article to illustrate the principles and implementation methods of the present invention. The description of the above embodiments is only used to help understand the method of the present invention and its core idea. It should be pointed out that for ordinary technicians in this technical field, without departing from the principle of the present invention, several improvements and modifications can be made to the present invention, and these improvements and modifications also fall within the scope of protection of the claims of the present invention.
