Description

Technical Field

[0001] This application relates to the field of seismic exploration equipment technology, and more specifically, to a special vehicle for transporting a special trailer for petroleum geophysical exploration. Background Technology

[0002] Marine exploration transition zone projects make extensive use of several types of outboard motors, which are typically used for transporting personnel and goods between deep water areas and land.

[0003] Only a small portion of the routine maintenance and repair work on the outboard motor can be carried out on the water; most must be done on shore. For example, replacing the outboard motor engine requires first mooring the outboard motor at the dock and then using a crane to lift and replace the engine. Underwater maintenance and repairs, such as changing the engine gearbox oil, repairing the hull and rubber airbags, and cleaning debris from the bilge, all require the entire outboard motor to be lifted and placed on land using a large-tonnage crane. However, during field operations, suitable docks and temporary mooring points (meeting the requirements of water depth, flat and firm land surface, and open space) are often unavailable near the work area to moor the outboard motor and crane. Furthermore, renting local docks and cranes requires advance booking, resulting in substantial rental costs. In addition, outboard motor maintenance and repair work is often not carried out at any time and place due to various third-party reasons. These factors have seriously affected the progress of routine maintenance and repair of the outboard motor, thereby impacting production schedules. Utility Model Content

Optionally, the special vehicle includes a first working state and a second working state; In the first working state, the first driving member drives the end of the middle frame near the front of the vehicle to rise, and the second driving member drives the upper frame to slide relative to the middle frame to the rear of the vehicle. The upper frame and the middle frame are tilted relative to the lower frame. In the second operating state, the first driving member drives the end of the middle frame near the front of the vehicle to descend and reset, and the second driving member drives the upper frame to slide and reset relative to the middle frame towards the front of the vehicle.

[0018] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0019] In related technologies, when an outboard motor needs to be towed ashore for maintenance, a suitable location (meeting the parking requirements of both the crane and the outboard motor) is usually found first. Then, the crane is used to lift the outboard motor to the shore and place it for maintenance. After maintenance, the crane is used to lift the outboard motor back into the water. However, in daily production, the shoreline in most work areas is soft and narrow, making it difficult to park cranes. Furthermore, the water depth near the shore is usually shallow, making it difficult to find a place to moor boats. Suitable locations for simultaneously parking cranes and outboard motors are scarce. If maintenance is carried out at a local dock, it usually requires a long journey, which is very time-consuming.

[0020] In view of this, this application proposes a special vehicle for transporting a special trailer for petroleum geophysical exploration.

[0021] In this embodiment, "front" refers to the direction closer to the front of the vehicle, and "rear" refers to the direction closer to the rear of the vehicle.

[0022] See Figure 1 and Figure 2 A special vehicle for transporting petroleum geophysical exploration trailers, comprising: A lower frame 1, on which a front wheel assembly 61 and a rear wheel assembly 62 are mounted; The middle frame 2 is disposed above the lower frame 1, and the end of the middle frame 2 near the rear of the vehicle is hinged to the lower frame 1. The end of the middle frame 2 near the front of the vehicle can rotate around the hinge position. The first driving component 41 is disposed on the lower frame 1 and connected to the middle frame 2, and is used to drive the end of the middle frame 2 near the front of the vehicle to lift, so that the end of the middle frame 2 near the front of the vehicle is higher than the end of the middle frame 2 near the rear of the vehicle. The upper frame 3 is disposed above the middle frame 2 and slidably connected to the middle frame 2; The second driving component 42 is disposed on the middle frame 2 and connected to the upper frame 3, and is used to drive the upper frame 3 to slide relative to the middle frame 2 in the front-rear direction of the vehicle. The winch system 5 is installed on the upper frame 3 and is used to drag the trailer onto the upper frame 3 and fix it. Specifically, the special vehicle has a three-layer frame structure, including a lower frame 1, a middle frame 2, and an upper frame 3. The lower frame 1 serves as the basic support structure of the entire vehicle, bearing the weight of the vehicle and its driving function. The front wheel assembly 61 and the rear wheel assembly 62 are installed on the lower frame 1 to facilitate vehicle movement.

[0023] The middle frame 2 is positioned above the lower frame 1. The rear end of the middle frame 2 is hinged to the lower frame 1, and the front end of the middle frame 2 can rotate around the hinged position, meaning the front end of the middle frame 2 can move up and down relative to the lower frame 1. A first drive unit 41 is mounted on the lower frame 1 and connected to the middle frame 2. The first drive unit 41 can drive the front end of the middle frame 2 to rise relative to the lower frame 1, causing the middle frame 2 to tilt with the front end higher than the rear end. The upper frame 3 is mounted on the middle frame 2, serving as a platform for placing and securing the trailer. It can tilt in the same direction as the middle frame 2, facilitating smooth loading and unloading of the trailer during loading and unloading.

[0024] The upper frame 3 is slidably connected to the middle frame 2, allowing the upper frame 3 to slide relative to the middle frame 2 along the vehicle's longitudinal direction. A second drive unit 42 is mounted on the middle frame 2 and connected to the upper frame 3, providing driving force for the relative sliding of the upper frame 3. When loading or unloading the trailer in deep water, the second drive unit 42 drives the upper frame 3 to slide rearward, extending it into the deep water area for easier loading and unloading. A winch system 5 is installed on the upper frame 3, which can be connected to the trailer via ropes or other tools to provide strong pulling force, smoothly dragging the trailer from the water onto the upper frame 3 and securing it, ensuring the trailer's stability on the vehicle.

[0025] In this embodiment, by setting up a liftable and extendable vehicle body structure, efficient transportation of trailers can be achieved, reducing reliance on cranes and docks, avoiding lifting risks, and helping to improve maintenance efficiency and operational safety.

[0026] Optionally, the special vehicle includes a first working state and a second working state; In the first working state, the first driving member 41 drives the end of the middle frame 2 near the front of the vehicle to rise, and the second driving member 42 drives the upper frame 3 to slide relative to the middle frame 2 towards the rear of the vehicle. The upper frame 3 and the middle frame 2 are tilted relative to the lower frame 1. In the second working state, the first driving member 41 drives the end of the middle frame 2 near the front of the vehicle to descend and reset, and the second driving member 42 drives the upper frame 3 to slide and reset relative to the middle frame 2 towards the front of the vehicle. The upper frame 3 and the middle frame 2 remain horizontal with the lower frame 1.

[0027] In this embodiment, the special vehicle includes at least two working states: a first working state with the frame extended and a second working state with the frame retracted. Specifically, in actual use, when it is necessary to load the trailer from the water onto the vehicle, the first drive component 41 drives the front end of the middle frame 2 to rise, causing the middle frame 2 and the upper frame 3 to form an inclined state with the front higher than the rear. At the same time, the second drive component 42 drives the upper frame 3 to slide rearwards, extending the upper frame 3 to the vicinity of the trailer's position. At this time, the special vehicle is in the first working state, i.e., the frame extended state, which facilitates loading the trailer onto the vehicle or unloading the trailer into the water. In actual use, the distance by which the upper frame 3 extends rearward relative to the middle frame 2 can be flexibly adjusted according to the distance of the trailer's location.

[0028] After the trailer is loaded, the second drive unit 42 drives the upper frame 3 to slide forward and reset, retracting the upper frame 3. The first drive unit 41 drives the front end of the middle frame 2 to descend and reset, so that the middle frame 2 and the upper frame 3 return to the same horizontal state as the lower frame 1. At this time, the special vehicle is in the second working state, that is, the frame is retracted. At this time, the trailer is stably fixed on the vehicle. The trailer can be maintained and repaired on the spot according to the actual situation, or the trailer can be transported to the designated repair location.

[0029] Optionally, the bottom of the upper frame 3 is provided with a slide rail, and the middle frame 2 includes a guide post 21 that slides with the slide rail.

[0030] For details, see Figure 4 In this embodiment, the middle frame 2 includes two parallel guide posts 21, and a slide rail is provided at the bottom of the upper frame 3. The slide rail and the guide posts 21 are slidably engaged, so that the upper frame 3 can slide smoothly back and forth on the middle frame 2 along the guide posts 21. This can prevent the upper frame 3 from deviating and shaking during the sliding process, and ensure the smoothness and reliability of the upper frame 3 during the sliding process.

[0031] In other embodiments, the relative sliding between the upper frame 3 and the middle frame 2 can also be achieved by other means such as chain and sprocket mechanisms, which will not be elaborated here.

[0032] Optionally, the first drive unit 41 includes a first hydraulic cylinder assembly, the cylinder of the first hydraulic cylinder assembly is hinged to the lower frame 1, and the piston rod end of the first hydraulic cylinder assembly is hinged to the middle frame 2; the second drive unit 42 includes a second hydraulic cylinder assembly, the cylinder of the second hydraulic cylinder assembly is connected to the middle frame 2, and the piston rod end of the second hydraulic cylinder assembly is connected to the upper frame 3.

[0033] Specifically, the first driving component 41 includes a first hydraulic cylinder assembly, which is located at the front end of the lower frame 1. Specifically, it may include two first hydraulic cylinders 411, which are arranged on opposite sides of the middle frame 2. The cylinder barrel end of the first hydraulic cylinder 411 is hinged to the lower frame 1, and the piston rod end of the first hydraulic cylinder 411 is hinged to the middle frame 2. Figure 5 As shown, the piston rod of the first hydraulic cylinder 411 extends, pushing the front end of the truss 2 to rise; as Figure 6 As shown, the piston rod of the first hydraulic cylinder 411 retracts and resets, causing the front end of the truss 2 to descend and reset.

[0034] The second driving component 42 includes a second hydraulic cylinder assembly, which may specifically include two second hydraulic cylinders 421. The two second hydraulic cylinders 421 are respectively disposed on both sides of the center frame 2 and are arranged along the extending direction of the center frame 2. (See also...) Figure 7 The cylinder end of the second hydraulic cylinder 421 is fixedly connected to the middle frame 2, and the piston rod end of the second hydraulic cylinder group is fixedly connected to the upper frame 3. The extension of the piston rod of the second hydraulic cylinder 421 pushes the upper frame 3 to slide and extend to the rear of the vehicle, and the contraction of the piston rod of the second hydraulic cylinder 421 drives the upper frame 3 to slide and reset to the front of the vehicle.

[0035] Optionally, the upper frame 3 includes a first region 31 and a second region 32; along the left-right direction of the vehicle, the first region 31 is located in the middle of the upper frame 3, and the second region 32 is located on both sides of the first region 31; the interior of the first region 31 is hollow, and a plurality of support platforms 11 are provided on the lower frame 1 at positions corresponding to the first region 31, and the plurality of support platforms 11 are spaced apart along the front-rear direction of the vehicle; in the second working state, the top surface of the support platform 11 is higher than the top surface of the upper frame 3.

[0036] See Figure 8 In this embodiment, the upper frame 3 is a rectangular frame structure. Along the left-right direction of the vehicle, i.e., the width direction, the upper frame 3 can be divided into three parallel rectangular regions: a first region 31 in the middle and two second regions 32 on either side. The first region 31 is a hollow rectangular frame structure; please refer to [reference needed]. Figure 2 and Figure 3 Multiple support platforms 11 are provided on the lower frame 1 at positions corresponding to the first area 31, and the multiple support platforms 11 are spaced apart along the front-rear direction of the vehicle. When the vehicle is in the second working state, that is, when the frame is retracted, the support platforms 11 can be exposed from the hollow first area 31, and the top surface of the support platform 11 is higher than the top surface of the upper frame 3, thereby providing support for the bottom of the trailer fixed to the upper frame 3 and ensuring the stability of the trailer.

[0037] Optionally, a plurality of roller assemblies 311 are provided in the first region 31, and the plurality of roller assemblies 311 are distributed at intervals along the front-rear direction of the vehicle, and the top surface of the roller assembly 311 is higher than the top surface of the upper frame 3; in the second working state, the positions of the plurality of roller assemblies 311 and the plurality of support platforms 11 are staggered, and the top surface of the roller assembly 311 is flush with the top surface of the support platform 11.

[0038] Preferably, a plurality of roller assemblies 311 are provided in the first region 31, spaced apart along the front-rear direction of the vehicle. The top surface of the roller assembly 311 is higher than the top surface of the upper frame 3. When towing the trailer onto the upper frame 3, the roller assembly 311 can contact the bottom surface of the trailer, reducing the friction between the trailer and the upper frame 3 through rolling, making the towing of the trailer easier and smoother. When the vehicle is in the second working state, that is, the frame is retracted, the positions of the multiple roller assemblies 311 and the multiple support platforms 11 are staggered to avoid interference between their positions. The top surface of the roller assembly 311 is flush with the top surface of the support platform 11, so when the trailer is placed on the support platform 11, the roller assembly 311 can also work with the support platform 11 to provide stable support for the trailer, further enhancing the stability of the trailer on the vehicle.

[0039] Optionally, a plurality of support plates 321 are provided in the second region 32. The side of the support plate 321 closest to the first region 31 is hinged to the upper frame 3, and the side of the support plate 321 away from the first region 31 can rotate around the hinge position. A lifting device 7 is installed on the lower frame 1. The lifting device 7 is connected to the support plate 321 and is used to drive the side of the support plate 321 away from the first region 31 to lift, so that the support plate 321 and the upper frame 3 form an angle.

[0040] In practical applications, there are many types of trailer hitches, and different types may have different structures. For trailer hitches with a curved bottom, when they are dragged onto the upper frame 3, the side of the curved bottom facing the vehicle (or the ground) is convex, which can easily cause them to sway from side to side. To further improve the support for such trailer hitches, in this embodiment, multiple support plates 321 are provided in the second region 32 of the upper frame 3, and the support plates 321 are spaced apart along the length of the vehicle.

[0041] like Figure 8As shown, to facilitate the installation of the support plate 321, the second region 32 is composed of multiple rectangular frames arranged along the vehicle's longitudinal direction, i.e., its length, with multiple support plates 321 spaced apart within the rectangular frames. Specifically, the side of the support plate 321 closest to the first region 31 is hinged to the upper frame 3, while the side of the support plate 321 furthest from the first region 31 can rotate around the hinged position. By driving the lifting device 7 to raise the side of the support plate 321 furthest from the first region 31, an angle can be formed between the support plate 321 and the upper frame 3. (See Figure 1) Figure 9 From the cross-section of the vehicle, the left and right support plates 321 exhibit an inclined state with the outer side higher and the inner side lower, thus providing good support for the left and right sides of the arc-shaped bottom of the trailer. On this basis, the collaborative support platform 11 and roller assembly 311 support the lowest point in the middle of the arc-shaped bottom, which can effectively reduce the left and right swaying of the arc-shaped bottom trailer and ensure the stability of the fixed position.

[0042] The number of support platform 11, roller assembly 311 and support plate 321 can be increased or decreased according to actual use. The size of support plate 321 can be designed according to the shape of the hanging machine.

[0043] In this embodiment, the lifting device 7 may include a third hydraulic cylinder group, which may include multiple third hydraulic cylinders 71, the specific number of which is adapted to the number of support plates 321. The bottom of the cylinder of the third hydraulic cylinder 71 is fixedly connected to the lower frame 1, and the end of the piston rod of the third hydraulic cylinder 71 is slidably connected to the outer side of the support plate 321. Figure 9 As shown, the piston rod of the third hydraulic cylinder 71 extends, causing the outer side of the support plate 321 to rise; as Figure 10 As shown, the retraction and reset of the piston rod of the third hydraulic cylinder 71 causes the outer side of the support plate 321 to descend and reset.

[0044] In other embodiments, the lifting device 7 may also be a hydraulic jack, an electric push rod, or other mechanical lifting structure.

[0045] Optionally, the special vehicle further includes a power system and a control system; the power system is connected to the first drive component 41, the second drive component 42, and the winch system 5, and is used to provide a power source for the first drive component 41, the second drive component 42, and the winch system 5; the control system is connected to the first drive component 41, the second drive component 42, and the winch system 5, and is used to control the operation of the first drive component 41, the second drive component 42, and the winch system 5.

[0046] In this embodiment, both the power system and the control system can be located in the front end area of ​​the lower frame 1. Specifically, the power system may include a battery pack, an external 220V fast charging port, a solar charging system, an electric hydraulic pump, and a hydraulic oil tank. The electric hydraulic pump provides a high-pressure hydraulic oil source to power the operation of the first, second, and third hydraulic cylinder groups, while the battery pack powers the electric hydraulic pump, electric winch, and other equipment. During the day when there is sufficient sunlight, the solar charging system can automatically charge the battery pack. If necessary, the external 220V fast charging port can also be used to charge the battery pack. Both charging methods ensure that the system has a sufficient power source during operation. In addition, the power system may also include an engine. When the usage frequency is high and the power supply is insufficient, a small engine can be selected to provide power, which is compatible with the hydraulic pump and hydraulic winch.

[0047] The control system may include a control panel and control handles. The control panel is equipped with various pressure gauges, switches, and alarm lights. The pressure gauges display the hydraulic oil pressure, the switches control the extension and retraction of each hydraulic cylinder, the winch's raising and lowering, and emergency stops, etc., and the alarm lights monitor hydraulic pressure and battery level, issuing an alarm when levels exceed limits. The external control handle has the same function as the switches on the control panel. The movement of the hydraulic cylinders, winch, etc., can be achieved using an external electric control handle in conjunction with solenoid hydraulic valves, or by using mechanically controlled hydraulic valves.

[0048] Controlling or monitoring the working status of each component through a control system is a well-known technique to those skilled in the art, and will not be elaborated upon here.

[0049] Optionally, a tow hook is also provided at the end of the lower frame 1 near the front of the vehicle.

[0050] Specifically, the special vehicle described in this embodiment has no driving force of its own, and a tow hook is set at the front end of the lower frame 1, which can facilitate the movement of the special vehicle by auxiliary vehicles such as pickup trucks.

[0051] Optionally, the front wheel assembly 61 includes a swivel wheel, which is connected to the lower frame 1 via a folding mechanism; the rear wheel assembly 62 includes multiple sets of wide-tire wheels, which are spaced apart along the longitudinal direction of the vehicle.

[0052] Specifically, the front wheels use swivel casters for easy vehicle steering. These casters are connected to the lower frame 1 via a folding mechanism, allowing them to be unfolded or folded as needed. For example, during loading or unloading, the casters can be unfolded to facilitate adjusting the vehicle's direction and provide support to the front of the vehicle, maintaining stability. During long-distance, high-speed transport, the casters can be folded down to reduce drag and energy consumption, facilitating high-speed driving.

[0053] The rear wheels use multiple sets of wide tires spaced apart along the front-rear direction of the vehicle, which can increase the contact area between the vehicle and the ground, improve the vehicle's load-bearing capacity and stability. At the same time, the wide tires can also distribute the vehicle's weight, reduce the pressure on the ground, prevent the vehicle from being stuck on soft ground in the field, and help reduce the terrain requirements for maintenance sites.

[0054] The following details the workflow of this special vehicle in actual operation.

[0055] When it is necessary to load the trailer from the water onto the vehicle, firstly, an auxiliary vehicle such as a pickup truck is used to tow the special vehicle to a suitable location on the shore. Then, the control system is activated, putting the vehicle into its first working state. The first drive unit 41 (first hydraulic cylinder group) starts working, and its piston rod extends, pushing the end of the middle frame 2 near the front of the vehicle to rise, so that the middle frame 2 and the upper frame 3 are tilted relative to the lower frame 1, with the front higher than the rear. At the same time, the second drive unit 42 (second hydraulic cylinder group) drives the upper frame 3 to slide relative to the middle frame 2 towards the rear of the vehicle, allowing the upper frame 3 to extend into the deep water area.

[0056] At this point, the operator connects the rope of the winch system 5 to the trailer and starts the winch system 5. The winch rotates, slowly dragging the trailer onto the upper frame 3. During the dragging process, the roller assembly 311 in the first area 31 of the upper frame 3 reduces the friction between the trailer and the upper frame 3, allowing the trailer to be dragged onto the vehicle more smoothly. Once the trailer has been dragged to the appropriate position on the upper frame 3, the winch system 5 is used to secure the trailer.

[0057] Next, the control system switches the vehicle from the first working state to the second working state. The second drive component 42 (second hydraulic cylinder group) drives the upper frame 3 to slide and reset relative to the middle frame 2 towards the front of the vehicle. The first drive component 41 (first hydraulic cylinder group) drives the end of the middle frame 2 near the front of the vehicle to descend and reset, ultimately keeping the upper frame 3 and the middle frame 2 level with the lower frame 1. For trailers with a flat bottom, the support platform 11 and roller assembly 311 on the lower frame 1 jointly support the bottom of the trailer, providing support and ensuring the stability of the trailer. For trailers with a curved bottom, the support platform 11 and roller assembly 311 jointly support the lowest point of the curved bottom. The control system controls the lifting device 7 (third hydraulic cylinder group) to raise the outer side of the support plate 321 in the second area 32. The inclined support plate 321 supports the left and right sides of the curved bottom, preventing the trailer from shaking. After the trailer is stably fixed on the vehicle, it can be repaired on-site according to the actual situation, or the trailer can be safely transported to a designated repair location.

[0058] After the maintenance is completed, the trailer needs to be unloaded to the original working water area, and the control system should be restarted to put the vehicle into the first working state. Following the reverse operation procedure of loading, first release the winch system 5 from the trailer, and then operate the winch system 5 in reverse to remove the trailer from the upper frame 3.

[0059] The special vehicle provided in this embodiment for transporting petroleum geophysical exploration trailers can be maintained and repaired at any suitable location in the field without being restricted by terrain. It is also simple and convenient to operate, and one person can easily tow the trailer from the water to the shore. It can transport various types of trailers, greatly reducing the dependence on cranes and docks, significantly reducing costs and lifting risks, improving the efficiency of trailer maintenance and ensuring the safety of maintenance operations.
