Abstract
Description
Technical Field
[0001] This invention relates to the field of VC shallow drilling technology, and more particularly to a take-up and release device for VC shallow drilling equipment. Background Technology
[0002] VC shallow drilling is a mature technology used in engineering surveys abroad and its application areas are constantly expanding. For example, Ghana's Tema PMI company uses 5m long shallow drills for sand source exploration; Fugro has also proposed using shallow drilling as a core sampling method at the Kuwait LNG terminal. In China, the application of shallow drilling is relatively limited, indicating potential for market development, particularly in areas such as rapid core sampling and testing of dredged soil, surface sediment research, and sand resource exploration.
[0003] Shallow drilling rigs are integrated engineering instruments, with a large overall size, requiring vessels with sufficient power and operating space, and are generally deployed and retrieved using cranes. However, since the use of ordinary VC shallow drilling rigs requires the assistance of cranes, the availability of vessels equipped with cranes is extremely limited, especially in some regions and countries where such vessels are simply unavailable. In such cases, a less desirable approach is to use a vessel mounted on a crawler crane. This method presents greater challenges in securing and deploying the crane, requiring more time for preparation and incurring higher costs. Furthermore, crawler cranes, being land-based lifting equipment, lack dedicated welding points for fixing their base and tracks, resulting in relatively poor stability when mounted on a vessel. This is particularly problematic at sea, where the vessel is already in a state of swaying, making it more prone to imbalance when lifting heavy objects. Summary of the Invention
[0004] The purpose of this invention is to solve the problems existing in the prior art and to propose a launching and taking-up device for VC shallow drilling equipment.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0012] Preferably, the container is provided with a first traction wheel, and the first mounting base is provided with a second traction wheel. When the container is in a pulled state, the end of the first steel cable away from the push-pull roller is directly connected to the first traction wheel; when the container is in a pushed state, the end of the first steel cable away from the push-pull roller passes around the second traction wheel and is connected to the first traction wheel.
[0013] Preferably, the winch assembly further includes a take-up and release roller disposed on the reducer, the take-up and release roller being disposed on the side of the reducer away from the push-pull roller, and a cable pressing roller being elastically disposed on the mounting frame, the cable pressing roller being movable against the take-up and release roller, the second steel cable being sleeved on the take-up and release roller, and the end of the second steel cable away from the take-up and release roller passing through the first lifting point and the main body of the equipment in sequence and finally connected to the second lifting point.
[0014] Preferably, the main body of the equipment is provided with two vertical pulleys, which are symmetrically arranged on the main body of the equipment, and a horizontal pulley is provided between the two vertical pulleys.

[0031] Example:
[0032] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 A launching and recovering device for VC shallow drilling equipment includes two sets of guide rails 1 fixed on a deck, a container 2 slidably mounted on the guide rails 1, and a winch assembly for driving the displacement of the container 2. The container 2 has openings 201 on both the upper and lower sides. A support assembly is provided at the opening 201 on the lower side of the container 2. The support assembly is provided with the main body 3 for shallow drilling sampling. The main body 3 is movably mounted on both sides of the main body 3. Each set of guide rails 1 is fixedly connected to a first mounting seat 5 and a second mounting seat 501. The first mounting seat 5 and the second mounting seat 501 are both welded to the deck. The first mounting seat 5 and the second mounting seat 501 are also provided with an A-frame 6 for providing support and lifting points for the launching and recovering of the main body 3. The A-frame 6 is slidably mounted with the container 2. The winch assembly is fitted with a first steel cable 7 and a second steel cable 8, which are used to pull the container 2 and the main body 3, respectively.
[0033] Specifically, since potential projects for equipment application may be distributed across various coastal areas of the country and even other countries overseas, the equipment may need to be transported to the site via land or sea. Considering that container 2 is currently the most common method of full-load sea and land transport, the design and manufacture of the auxiliary loading and unloading device is based on container 2, striving to maximize the use of public resources for subsequent deployment and achieve the goal of rapid transportation with minimal transportation costs. The entire container frame is processed and manufactured according to the dimensions of a standard 20-foot container 2, with an overall steel structure welded, ensuring structural safety and reliability, and possessing all the characteristics required for container 2 transportation: the four corners of the top are designed as lifting points for easy lifting; the two sides (longitudinal direction) are designed as double doors, using container 2 hinges, locking rods, brackets, bars, door seals, etc.; the top of container 2 is detachable and fixed around the perimeter with lifting bolts; the lifting bolts are required to have metal and rubber sealing gaskets for rain protection after tightening, etc. The container can store the main body of the transport equipment 3, sampling tube supports, and other storage shelves; the container is slidable on the deck through a winch assembly in conjunction with an A-frame 6, allowing the container to... The equipment can be moved off the deck without requiring workers to install a working platform outside the ship's side. The winch assembly can then lower the equipment via the second steel cable 8. A support beam 9 is installed at the opening 201 on the bottom side of the container to support the weight of the main equipment 3 during placement and transportation. When the support beam 9 is open (parallel to the container), the main equipment 3 can be freely lowered and lowered from the middle of the opening 201. When the equipment is retracted, the support beam 9 is adjusted to the closed position (tilted at the opening 201) to support the equipment. After the equipment is lowered, the mobile platform 4 can be flipped to seal the opening 201, providing a safe and reliable operating platform for 2-3 operators. This invention meets the equipment storage and transportation requirements of shipping and freight transport. Equipped with an A-frame 6 and a winch, it can, to some extent, replace a crane for rapid lowering and lowering of shallow drilling equipment, reducing the requirements for ships and auxiliary equipment during operation. It can be quickly deployed to the site, increasing the equipment's adaptability, saving costs, and improving efficiency.
[0034] Reference Figure 4 As a preferred technical solution of the present invention, the support component includes two sets of symmetrically arranged support beams 9. Each support beam 9 is rotatably set inside the container 2 by a pin. A first positioning hole 901 is opened on the frame of the container 2. A first pin 902 is movably arranged on the support beam 9 and is movably connected in the first positioning hole 901.
[0035] Specifically, when the support beams 9 on both sides are inclined at the opening 201, the first pin 902 enters the first positioning hole 901 to limit and fix the support beam 9, and the support beam 9 is in the closed state. At this time, the support beam 9 supports the main body 3 of the equipment. When the first pin 902 moves out of the first positioning hole 901, the support beam 9 is parallel to the outer frame of the box. At this time, the opening 201 on the bottom side of the box is opened, and the main body 3 of the equipment can be lowered from the opening 201, so that the equipment can be lowered quickly.
[0036] Reference Figure 4 As a preferred technical solution of the present invention, the bottom of the mobile platform 4 is rotatably connected to the container 2 via a hinge. Both the mobile platform 4 and the container 2 are provided with matching eye bolt holes 10, and the two eye bolt holes 10 are connected by a cable.
[0037] Specifically, the mobile platform 4 is an operating platform that can be opened and laid flat. The bottom of the mobile platform 4 is hinged to the housing. The side of the housing where the mobile platform 4 is located is equipped with a sliding door for easy maintenance and ventilation. During transportation, the platform leans against the two sides of the housing and is fixed to the lifting eye bolt holes 10 with cables. Before the equipment is lowered, the fixing cables are loosened. The platform leans against the equipment under its own weight and is lowered with the equipment until it is in a horizontal position. The outriggers are attached to the other side of the housing, providing a safe and reliable operating platform for the operators. It can support 2-3 operators to operate the equipment at the same time.
[0038] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As a preferred technical solution of the present invention, the A-frame 6 includes a support rod 601 hinged to the first mounting base 5 and a telescopic rod 602 hinged to the second mounting base 501. The end of the telescopic rod 602 away from the second mounting base 501 is movably connected to the support rod 601 through a pin. The end of the support rod 601 away from the first mounting base 5 is fixedly connected to a crossbeam 603. The crossbeam 603 is provided with a first lifting point 6031 and a second lifting point 6032.
[0039] Furthermore, the strut 601 is provided with a cam groove 6011, and an auxiliary wheel 6012 is movably connected within the cam groove 6011. The auxiliary wheel 6012 is mounted on the container 2 via a support.
[0040] Furthermore, the winch assembly includes a mounting frame 11 fixed on the deck, a drive motor 111 is mounted on the mounting frame 11, a reducer 112 is connected to the output end of the drive motor 111, a push-pull roller 113 is connected to the reducer 112, a first steel cable 7 is sleeved on the push-pull roller 113, and the first steel cable 7 achieves the push-pull action on the container 2 through different winding methods.
[0041] Furthermore, the container 2 is equipped with a first traction wheel 202, and the first mounting base 5 is equipped with a second traction wheel 502. When the container 2 is in a pulled state, the end of the first steel cable 7 away from the push-pull roller 113 is directly connected to the first traction wheel 202; when the container 2 is in a pushed state, the end of the first steel cable 7 away from the push-pull roller 113 passes around the second traction wheel 502 and is connected to the first traction wheel 202.
[0042] Specifically, by controlling the operation of the drive motor 111, the reducer 112 can convert the high-speed, low-torque motor input energy into low-speed, high-torque energy and output it to the push-pull roller 113. The push-pull roller 113 winds up and unwinds the first steel cable 7. When pushing the box, the first steel cable 7 connected to the push-pull roller 113 passes through the second traction wheel 502 on the first mounting base 5 and finally connects to the first traction wheel 202 on the box. The push-pull roller 113 is controlled to wind up the first steel cable 7, and the steel cable pulls the box to slide on the guide rail 1 and move it off the deck, so that the box can act as a temporary working platform without changing the ship's outer beam or building a platform beyond the ship's side. When the box is pulled back, it causes the first steel cable 7 to slide on the guide rail 1 and move off the deck, so that the box can act as a temporary working platform without changing the ship's outer beam or building a platform beyond the ship's side. The first steel cable 7, connected to the push-pull roller 113, is directly connected to the first traction wheel 202 on the container. When the steel cable is wound up, the container extending outside the deck can be pulled back directly. It has the function of switching between working mode and non-working mode. It does not require the auxiliary ship to go to the ship's side for processing operations, does not change the ship's outer pipe, and does not affect the ship's dispatch. It is efficient, convenient, safe and firm. During the sliding of the container 2, the A-frame 6 can swing in conjunction with the container, so that the telescopic rod 602 can be stretched or contracted, providing support and lifting points for the equipment to be deployed and retracted, and providing fulcrum for the push-pull of the container. The telescopic rod 602 is fixed with pins after it is swung out for operation and after it is retracted to the ship to prevent the telescopic rod 602 from sliding and affecting the stability of the equipment.
[0043] Reference Figure 1 , Figure 2 , Figure 6 and Figure 7 As a preferred technical solution of the present invention, the winch assembly further includes a take-up and release roller 114 disposed on the reducer 112. The take-up and release roller 114 is disposed on the side of the reducer 112 away from the push-pull roller 113. A cable pressing roller 115 is also elastically disposed on the mounting frame 11. The cable pressing roller 115 and the take-up and release roller 114 are movably abutted against each other. The second steel cable 8 is sleeved on the take-up and release roller 114. The end of the second steel cable 8 away from the take-up and release roller 114 passes through the first lifting point 6031 and the equipment body 3 in sequence and is finally connected to the second lifting point 6032.
[0044] Furthermore, the main body 3 of the equipment is provided with two vertical pulleys 301, which are symmetrically arranged on the main body 3 of the equipment. A horizontal pulley 302 is provided between the two vertical pulleys 301. The second steel cable 8 is movably connected to the two vertical pulleys 301 and the horizontal pulley 302.
[0045] Specifically, after the container is pushed off the deck by the winch assembly, the first steel cable 7 on the push-pull roller 113 of the winch is removed. Then, the second steel cable 8 connected to the take-up roller 114 is used to connect to the equipment. The end of the second steel cable 8 away from the take-up roller 114 passes through the first lifting point 6031 on the crossbeam 603, the first vertical pulley 301 on the equipment body 3, the horizontal pulley 302, and the second vertical pulley 301 on the equipment body 3 in sequence, and finally connects to the second lifting point 6032 on the crossbeam 603. The equipment is then slowly lowered into the sea. During take-up and take-down, the cable pressing roller 115 helps to neatly collect the steel cable onto the take-up roller 114.
[0046] Reference Figure 1 , Figure 2 and Figure 4 As a preferred technical solution of the present invention, the guide rail 1 is provided with a first limiting roller 101 and a second limiting roller 102 for limiting the front, back and left and right positions of the container 2. The first limiting roller 101 and the second limiting roller 102 are both movably connected to the container 2.
[0047] Specifically, by setting limit rollers on guide rail 1, the front, back, left and right positions of the container can be limited, and the frictional resistance of the container movement can be reduced. At the same time, a positioning connecting bolt can be set in the middle of guide rail 1, which can be locked onto container 2 during transportation and can be used for rough positioning during installation.
[0048] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
