Description

Technical Field

[0001] This utility model relates to the field of petroleum exploration technology, and in particular to a triangular rubber track for a controllable seismic source vehicle. Background Technology

[0002] Petroleum exploration refers to the process of using various exploration methods to understand the underground geological conditions, recognize the conditions for oil generation, storage, migration, accumulation, and preservation of oil and gas, comprehensively evaluate the oil and gas potential, identify favorable areas for oil and gas accumulation, find oil and gas traps, explore the area of ​​oil and gas fields, and clarify the oil and gas layer conditions and production capacity in order to find and identify oil and gas resources.

[0003] Controlled seismic source vehicles are the main excitation source equipment for geological exploration and need to travel to areas with different geological conditions for construction. In the existing technology, wheeled controlled seismic sources are difficult to travel in soft ground areas such as deserts and snow, and the safety risks such as slipping, overturning and getting stuck are high. Once a safety accident occurs, construction must be stopped and rescue operations must be carried out, which greatly reduces the efficiency of operation. Therefore, it is necessary to redesign a triangular rubber track for controlled seismic source vehicles to address the above problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a triangular rubber track for a controllable vibration source vehicle.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A triangular rubber track for a controllable vibration source vehicle includes a frame, a limiting plate, a rubber track, a drive frame, a rear guide wheel, a support wheel, a tensioning wheel, a tensioning device, a drive assembly, an axle, and a swing frame. One side of the drive assembly is installed and connected to the axle, and the other side is assembled with the drive frame.

[0007] One end of the limiting plate is connected to the vehicle frame, and the other end is connected to the drive frame to limit its displacement;

[0008] The rear guide wheel is installed at the rear of the drive frame, and the tension wheel is installed at the front of the drive frame. One end of the tensioning device is connected to the drive frame, and the other end is connected to the tension wheel to adjust the track tension.

[0009] The swing frame is installed below the drive frame, and the support rollers are assembled below the swing frame;

[0010] The rubber track covers the drive assembly, rear guide wheel, support wheel, and tension wheel, forming a triangular transmission structure.

[0011] Preferably, the limiting plate is made of steel, with one end hinged to the vehicle frame via a pin and the other end having a limiting elongated hole. The drive frame has a limiting post that matches the limiting elongated hole, and the limiting post can slide along the limiting elongated hole to achieve limiting and guiding of the drive frame.

[0012] Preferably, the rear guide wheel is mounted behind the drive frame via a bolt adjustment mechanism. The bolt adjustment mechanism includes a rear guide wheel shaft, a rear guide wheel bracket, a rear guide wheel mounting plate, mounting bolts, mounting nuts, adjusting bolts, adjusting nuts, and locking nuts. The bolt adjustment mechanism can adjust the axial direction of the rear guide wheel to correct the alignment of the rubber track.

[0013] Preferably, there are four support rollers, which are symmetrically installed in two groups on two swing frames. The swing frames are hinged to the drive frame by pins and can swing adaptively with the undulations of the ground.

[0014] Preferably, the tensioning device consists of an accumulator and a tensioning cylinder. One end of the cylinder is hinged to the drive frame via a pin, and the other end is connected to the tensioning wheel. The position of the tensioning wheel is adjusted by hydraulic drive.

[0015] Preferably, the drive assembly includes a transition plate, a drive wheel, and a drive shaft. The drive shaft is rotatably connected to the drive frame via bearings, and the transition plate is rigidly connected to the drive wheel and the axle via bolts to achieve power transmission.

[0016] Preferably, the inner ring of the rubber track is provided with drive teeth, and the outer periphery of the drive wheel of the drive assembly is provided with a drive roller adapted to the drive teeth, so that the rubber track can be driven to rotate through the meshing of the drive roller and the drive teeth.

[0017] The beneficial effects of this utility model are:

[0018] 1. By setting up a triangular rubber track structure, the rubber track covers the drive components, rear guide wheel, support wheel and tension wheel to form a large ground contact area, which significantly increases the contact area between the controllable seismic source vehicle and the ground, reduces the pressure on the ground, and can effectively reduce the phenomenon of getting stuck and slipping in soft ground areas such as deserts and snow. At the same time, it avoids the risk of overturning that wheeled equipment is prone to, and improves the safety of field exploration operations.

[0019] 2. By setting a sliding limit structure between the limit plate and the drive frame, the upward angle (α angle) and downward angle (β angle) of the drive frame are precisely limited by the sliding stroke of the limit post along the limit hole, so as to prevent the track from falling off or the driving posture from becoming unbalanced due to terrain undulations, and to ensure that the rigid limit is stable and reliable.

[0020] 3. By setting a rear guide wheel with a bolt adjustment mechanism, the direction of the rear guide wheel axis can be flexibly adjusted, which can not only make up for the manufacturing error of the initial installation, but also correct the track posture after the track drive teeth wear, ensuring that the track rolls up flat and avoids deviation or jamming.

[0021] 4. By setting up support rollers with swing brackets, the four support rollers are installed symmetrically in two groups. The swing brackets can swing adaptively with the undulations of the ground, so that the support rollers are always in close contact with the inner ring of the rubber track, ensuring that the track is in full contact with the ground, further increasing the ground contact area and improving driving stability.

[0022] 5. By setting up a tensioning device consisting of an accumulator and a tensioning cylinder, the track tension can be responded to in real time. When the track loosens due to wear or temperature changes, the tensioning wheel is automatically pushed to tension the track. When the track is subjected to excessive impact tension, the accumulator buffers the impact, preventing the track from being overstretched and damaged, significantly extending the service life of the rubber track and reducing maintenance costs.

[0032] 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.

[0033] Reference Figure 1-9 A triangular rubber track for a controllable vibration source vehicle includes a frame 1, a limiting plate 2, a rubber track 3, a drive frame 4, a rear guide wheel 5, a support roller 6, a tensioning roller 7, a tensioning device 8, a drive assembly 9, an axle 10, and a swing frame 11. One side of the drive assembly 9 is installed and connected to the axle 10, and the other side is assembled with the drive frame 4.

[0034] One end of the limiting plate 2 is connected to the frame 1, and the other end is connected to the drive frame 4 to limit its displacement;

[0035] The rear guide wheel 5 is installed at the rear of the drive frame 4, the tension wheel 7 is installed at the front of the drive frame 4, and one end of the tensioning device 8 is connected to the drive frame 4 and the other end is connected to the tension wheel 7 to adjust the track tension.

[0036] The swing frame 11 is installed below the drive frame 4, and the support roller 6 is assembled below the swing frame 11;

[0037] The rubber track 3 covers the drive assembly 9, rear guide wheel 5, support roller 6 and tension roller 7, forming a triangular transmission structure.

[0038] The limiting plate 2 is made of steel. One end of it is hinged to the frame 1 via a pin, and the other end is provided with a limiting elongated hole. The drive frame 4 is provided with a limiting post 12 that is adapted to the limiting elongated hole. The limiting post 12 can slide along the limiting elongated hole to achieve the limiting and guiding of the drive frame 4. Specifically, the limiting post 12 is rigidly connected to the drive frame 4 by bolts. When the limiting plate 2 rotates around the pin connected to the frame 1, the travel of the limiting post 12 sliding along the elongated hole directly determines the pitch angle range of the drive frame 4. When going uphill, the drive frame 4 pitches up, and the limiting post 12 slides down along the elongated hole until it touches the bottom of the elongated hole. At this time, the limiting plate 2 is stretched and limits the pitch angle (α angle). When going downhill, the drive frame 4 tilts down, and the limiting post 12 slides up along the elongated hole until the upper part of the limiting plate 2 contacts the frame 1, limiting the tilt angle (β angle) to avoid the tracks falling off or the driving posture becoming unbalanced due to excessive pitch.

[0039] The rear guide wheel 5 is mounted behind the drive frame 4 via a bolt adjustment mechanism. The bolt adjustment mechanism can adjust the axial direction of the rear guide wheel 5 to correct the alignment of the rubber track 3. The bolt adjustment mechanism includes a rear guide wheel shaft 20, a rear guide wheel bracket 19, a rear guide wheel mounting plate 18, mounting bolts 14, mounting nuts 13, adjusting bolts 15, adjusting nuts 17, and a locking nut 16. The rear guide wheel shaft 20 is mounted on the rear guide wheel bracket 19. The bracket is fixed to the mounting plate 18 by mounting bolts 14 and mounting nuts 13. The adjusting nut 17 is welded to the mounting plate 18. The adjusting bolt 15 is screwed into the adjusting nut 17 and abuts against the rear guide wheel bracket 19. By screwing in or out the adjusting bolt 15, an axial force can be applied to the bracket, thereby finely adjusting the axial angle of the rear guide wheel shaft 20 in the horizontal plane to make it perpendicular to the axis of the drive frame 4, ensuring that the rubber track 3 is flat and without deviation when rolled up. After adjustment, the adjusting bolt 15 is fixed by the locking nut 16 to prevent loosening.

[0040] Four track rollers 6 are provided, symmetrically mounted in two groups on two swing frames 11. The swing frames 11 are hinged to the drive frame 4 by pins and can swing adaptively with the undulation of the ground. The swing frame 11 includes an upper pin connecting part and a lower track roller mounting plate. The upper pin and the mounting hole of the drive frame 4 cooperate to form a rotating pair. The lower mounting plate fixes the track roller 6 through the track roller axle. When the controllable vibration source vehicle travels on undulating soft ground, the swing frame 11 can rotate freely around the pin, so that the track roller 6 is always in close contact with the inner ring of the rubber track 3, ensuring that the contact area between the track and the ground is maximized, reducing pressure and improving passability.

[0041] The tensioning device 8 consists of an accumulator 22 and a tensioning cylinder 23. One end of the cylinder is hinged to the drive frame 4 via a pin, and the other end is connected to the tensioning wheel 7. The position of the tensioning wheel 7 is adjusted by hydraulic drive. The cylinder end of the tensioning cylinder 23 is connected to the drive frame 4, and the piston rod end is hinged to the front swing frame 27 of the tensioning wheel 7. The accumulator 22 is connected to the cylinder via an oil pipe. When the rubber track 3 loosens due to wear or temperature changes, the accumulator 22 releases pressurized oil to push the piston rod of the cylinder to extend, which drives the tensioning wheel 7 to move forward and tension the track. When the track is subjected to excessive impact tension, the piston rod of the cylinder retracts, and the pressurized oil flows back to the accumulator 22 to buffer the impact, thereby achieving dynamic tension adjustment.

[0042] The drive assembly 9 includes a transition plate 24, a drive wheel 25, and a drive shaft 26. The drive shaft 26 is rotatably connected to the drive frame 4 via bearings. The transition plate 24 is rigidly connected to the drive wheel 25 and the axle 10 via bolts to achieve power transmission. The two ends of the drive shaft 26 are mounted in the bearing holes of the drive frame 4 via tapered roller bearings. The drive wheel 25 is connected to the drive shaft 26 via a key and is rigidly connected to the axle 10 via the transition plate 24. The outer ring is provided with a drive roller adapted to the rubber track 3. The power output end of the axle 10 is transmitted to the drive wheel 25 via the transition plate 24, driving the drive shaft 26 to rotate around the bearing. The drive roller meshes with the drive teeth of the inner ring of the track to achieve track circulation.

[0043] The inner ring of the rubber track 3 is provided with drive teeth, and the outer circumference of the drive wheel 25 of the drive assembly 9 is provided with a drive roller that matches the drive teeth. The rubber track 3 is driven to rotate by the meshing of the drive roller and the drive teeth. The rubber track 3 is made of high-strength wear-resistant rubber material. The inner ring drive teeth are evenly distributed in the circumference and form a tooth-roller meshing transmission with the drive roller of the drive wheel 25 to avoid slippage. The outer ring of the track is provided with anti-slip patterns to enhance the friction with soft ground (desert, snow and ice) and further reduce the risk of slippage.

[0044] In use, the triangular rubber track is assembled onto the controllable vibration source vehicle. The track posture is corrected by the bolt adjustment mechanism of the rear guide wheel 5 to ensure that it is rolled up flat. The tensioning device 8 is activated, and the position of the tensioning wheel 7 is adjusted by the tensioning cylinder 23 to make the rubber track 3 tensioned appropriately, so that there is no obvious indentation in the middle of the track when pressed by hand. After the tension of the rubber track 3 is adjusted, the controllable vibration source vehicle can be started. The axle 10 transmits power to the drive wheel 25 of the drive assembly 9 through the transition plate 24. The drive roller on the outer periphery of the drive wheel 25 and the rubber track 25 are connected to the drive wheel 25. The drive teeth of the inner ring of the rubber track 3 mesh with each other. As the drive wheel 25 rotates, it drives the rubber track 3 to rotate in a cycle, thereby enabling the controllable vibration source vehicle to travel. When the controllable vibration source vehicle travels on an uneven soft ground surface, the swing frame 11 will swing adaptively around the pin connected to the drive frame 4 due to the undulation of the ground. This ensures that the support roller 6 installed under the swing frame 11 is always in close contact with the rubber track 3, ensuring that the rubber track 3 can fully contact the ground, increasing the ground contact area, reducing the pressure on the ground, and effectively reducing the risk of getting stuck.

[0045] If the vehicle encounters an uphill section during driving, the drive frame 4 will tilt upwards. At this time, the limiting post 12 on the drive frame 4 will slide downwards along the limiting elongated hole of the limiting plate 2. The limiting plate 2 rotates counterclockwise around the pin shaft connected to the frame 1. When the limiting post 12 slides to the bottom of the limiting elongated hole, the two ends of the limiting plate 2 are pulled, limiting the drive frame 4 from tilting upwards further, thus avoiding an unsafe driving posture due to excessive tilting angle. When driving on a downhill section, the drive frame 4 tilts downwards, the limiting post 12 slides upwards along the limiting elongated hole, and the limiting plate 2 rotates clockwise. When the limiting plate 2 contacts the frame 1, the downward tilting angle of the drive frame 4 is limited, preventing dangerous driving conditions.

[0046] If the drive teeth of the rubber track 3 wear after prolonged use, causing unevenness when the track is rolled up, it can be adjusted again through the bolt adjustment mechanism of the rear guide wheel 5. Loosen the locking nut 16, rotate the adjusting bolt 15, and the adjusting bolt 15 applies axial force to the rear guide wheel bracket 19, thereby changing the axial direction of the rear guide wheel shaft 20, so that the rubber track 3 can be restored to a flat rolled-up state. After adjustment, tighten the locking nut 16 to fix the adjusting bolt 15. In addition, the accumulator 22 in the tensioning device 8 can absorb some pressure when the rubber track 3 is subjected to excessive tension due to impact during travel, playing a buffering role. When the rubber track 3 becomes loose, the accumulator 22 can release pressure, which, together with the tensioning cylinder 23, pushes the tensioning wheel 7 to ensure that the rubber track 3 always maintains a suitable tension, ensuring the normal driving and operating efficiency of the controllable vibration source vehicle.

[0047] 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.
