Description

Technical Field

[0001] The invention relates to a device for assisting a controllable vibrator vehicle to turn in situ, in particular to a slewing device for assisting a controllable vibrator vehicle to turn in situ. Background Art

[0002] At present, small-tonnage controllable source vehicles are widely used in seismic exploration and construction projects in densely populated places such as farmland and towns. In the actual construction process, small-tonnage controllable source vehicles are moved back and forth repeatedly as needed. When encountering narrow road construction, small-tonnage controllable source vehicles need to complete the movement by turning around or turning. Due to the limitations of terrain or road width, the controllable source vehicle is generally moved by reversing or taking a detour. However, this method has the following disadvantages: First, there is a blind spot when reversing, especially during construction at night, which can easily cause rollover or collision, and has poor safety; second, taking a detour will waste time and reduce construction efficiency to a certain extent. Summary of the invention

[0003] The purpose of the present invention is to provide a slewing device for assisting a controllable seismic source vehicle in turning on the spot, so that the controllable seismic source vehicle can rotate on the spot when turning around or turning in a narrow construction site, avoiding reversing or taking a detour, improving construction efficiency, and making the turning safer.

[0004] In order to achieve the above object, the technical solution adopted by the present invention is: A slewing device for assisting a vibrator vehicle to turn in situ, comprising an upper bearing plate for supporting the vibrator vehicle, a lower bearing plate for contacting the ground, and a rotating mechanism for causing the upper bearing plate and the lower bearing plate to rotate relative to each other; and also comprising a locking mechanism for stopping the upper bearing plate from rotating; The lower load-bearing plate is provided with at least six through holes, at least three of the through holes are provided with pulley mechanisms, and at least three of the through holes are provided with leveling mechanisms; The pulley mechanism comprises a mounting tube fixedly mounted at the through hole, a telescopic mechanism fixedly mounted in the mounting tube, and a pulley fixedly mounted on the telescopic mechanism. The pulley can be stored in the mounting tube through the telescopic mechanism so that the lower bearing plate contacts the ground, and can also be extended out of the mounting tube through the telescopic mechanism so that the pulley contacts the ground. The leveling mechanism includes a level meter fixed on the lower load-bearing plate, a support tube fixed at the through hole, and a hydraulic servo cylinder arranged in the support tube, the hydraulic servo cylinder is in contact with the ground, and the hydraulic rod of the hydraulic servo cylinder is hingedly arranged with the support tube; The locking mechanism includes a rotating ring fixed on the upper load-bearing plate and a clamping cylinder fixed on the lower load-bearing plate. The rotating ring is arranged on the side of the upper load-bearing plate facing the lower load-bearing plate, and the rotating ring is arranged concentrically with the upper load-bearing plate. The clamping cylinder is arranged on the arc where the rotating ring is projected to the lower load-bearing plate, and the signal output end of the level is connected to the signal input end of the clamping cylinder.

[0005] As a further limitation of the present invention, the telescopic mechanism is a gas cylinder or a hydraulic cylinder.

[0006] As another limitation of the present invention, the pulley is a universal wheel.

[0007] As a limitation of the present invention, an electromagnet is embedded in the upper bearing plate.

[0008] As a further limitation of the present invention, the upper load-bearing plate is provided with support holes for facilitating hand pushing.

[0009] As a further limitation of the present invention, the lower load-bearing plate is provided with an anti-skid layer for preventing skidding.

[0010] As a third limitation of the present invention, the upper load-bearing plate is made of hard alloy aluminum.

[0011] Due to the adoption of the above technical solution, the present invention has the following technical advances compared with the prior art: ① The upper load-bearing plate of the present invention is used to carry the controllable seismic source vehicle. The controllable seismic source vehicle and the upper load-bearing plate are combined together by static friction, and the resistance of the rotating device is small. Therefore, by pushing the controllable seismic source vehicle, the upper load-bearing plate can drive the controllable seismic source vehicle to rotate relatively around the lower load-bearing plate. As long as the construction area has a space that can make the controllable seismic source vehicle rotate in situ, the controllable seismic source vehicle can complete U-turns and turns, avoiding the process of reversing or taking a detour, saving time, and improving construction efficiency; and, the workers stand outside to push the controllable seismic source vehicle to rotate, with a wide field of vision, and can control the rotation or stop of the controllable seismic source vehicle at any time, with high safety and strong controllability; at the same time, the pulley can be extended or retracted, and when supporting the controllable seismic source vehicle, the lower load-bearing plate is in contact with the ground, with a large contact area and strong support stability. When moving the rotary device, the pulley is extended to contact the ground, and the rolling of the pulley is used to reduce the resistance of the moving rotary device, thereby reducing the labor intensity of the movement; ② The electromagnet on the upper bearing plate of the present invention can generate magnetism after being energized. When in use, it can be adsorbed together with the flat plate of the vibrator vehicle after being energized, thereby increasing the firmness of the contact between the two. The leveling mechanism can adapt to the ground conditions. When the ground is uneven, it can automatically adjust to keep the lower bearing plate in a horizontal state, thereby preventing the vibrator from tilting during the rotation process, and having a higher safety. At the same time, once the vibrator vehicle tilts, the clamping claw cylinder will clamp the upper bearing plate in time to generate resistance, so that the upper bearing plate stops rotating, and the steering is completed after timely adjustment. ③ The upper load-bearing plate of the present invention is made of hard alloy aluminum, which can not only reduce its own weight but also meet the supporting strength. The anti-skid layer can effectively increase the friction between the rotating device and the ground and improve the stability of rotation.

[0012] In summary, the present invention utilizes a rotating device to enable the controllable seismic source vehicle to rotate 360 ​​degrees on the spot. In places with smaller construction areas, it can also achieve U-turns in any direction without reversing or taking a detour. It has good controllability, high stability, and high safety, which improves construction efficiency. It is suitable for assisting small-tonnage controllable seismic source vehicles to achieve on-the-spot rotation in narrow construction areas. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0015] The present invention is further described in detail below by specific examples. It should be understood that the described examples are only used to explain the present invention, and are not intended to limit the present invention.

[0016] Embodiment A slewing device for assisting a vibrator vehicle to turn in situ like Figure 1As shown, this embodiment includes an upper bearing plate 1, a lower bearing plate 2 and a rotating mechanism, wherein the upper bearing plate 1 is used to support the controllable seismic source vehicle 7, the lower bearing plate 2 is used to contact the ground, and the rotating mechanism is used to make the upper bearing plate 1 and the lower bearing plate 2 rotate relative to each other. Because the entire rotary device is heavy, in order to facilitate transportation, this embodiment is provided with a pulley mechanism 4 on the lower bearing plate 2 to reduce labor intensity. Because some ground surfaces are uneven, if the controllable seismic source vehicle is turned in situ on an uneven ground, rollover may occur. Therefore, a leveling mechanism 8 is provided on the lower bearing plate 2 of this embodiment to ensure the level of the lower bearing plate 2. This embodiment is also provided with a locking mechanism 9. When the leveling mechanism 8 fails to level the lower bearing plate 2, or during the rotation process, the ground collapses and makes the lower bearing plate 2 non-level, the locking device 9 locks the upper bearing plate 1 and turns after leveling. When in use, the flat plate 71 of the controllable seismic source vehicle 7 falls on the upper load-bearing plate 1, generating static friction with the upper load-bearing plate 1. Since the resistance of the rotating mechanism is small, pushing the controllable seismic source vehicle 7 that has fallen on the upper load-bearing plate 1 can cause the controllable seismic source vehicle 7 to drive the upper load-bearing plate 1 to rotate in place around the lower load-bearing plate 2, thereby completing a U-turn or a turn.

[0017] Specifically, the rotating mechanism of this embodiment adopts a slewing bearing 3, which is a ball or roller structure, and rotates more smoothly. The upper bearing plate 1 and the lower bearing plate 2 are fixedly connected to the slewing bearing 3 by bolts, so that the upper bearing plate 1 and the lower bearing plate 2 can rotate relative to each other.

[0018] At least six through holes are provided on the lower load-bearing plate 2. In this embodiment, there are six through holes, three of which are provided with pulley mechanisms 4, and three of which are provided with leveling mechanisms 8. The pulley mechanisms 4 and the leveling mechanisms 8 are evenly spaced.

[0019] like Figure 2 , Figure 3 As shown, there are three pulley mechanisms 4, each including a mounting tube 41, a telescopic mechanism and a pulley 43. The telescopic mechanism is a cylinder 42 or a hydraulic cylinder. Each mounting tube 41 is fixedly mounted on the side of the through hole that is not in contact with the ground. This embodiment uses a cylinder 42, the fixed end of which is fixed in the mounting tube 41. The pulley 43 is fixedly mounted on the end of the piston rod of the cylinder 42 and can move with the extension and retraction of the piston rod of the cylinder 42. The pulley 43 uses a universal wheel and rotates smoothly. When the rotary device needs to be moved, the piston rods of the three cylinders 42 extend at the same time, driving the pulley 43 to extend out of the mounting tube 41 and first contact the ground. As the piston rod of the cylinder 42 is further extended, the entire rotary device is separated from the ground, and the entire rotary device is supported by the three pulleys 43 for easy pushing. When the slewing device needs to support the controllable vibrator vehicle 7, the piston rod of the cylinder 42 retracts, driving the pulley 43 to be stored in the installation tube 41, so that the lower bearing plate 2 contacts the ground, thereby improving the stability of the slewing device support.

[0020] like Figure 4 As shown, the leveling mechanism 8 includes a spirit level 81, a support cylinder 82 and a hydraulic servo cylinder 83. The spirit level 81 is fixed on the lower bearing plate 2, and the support cylinder 82 is fixed on the three through holes of the lower bearing plate 2, and is spaced apart from the mounting cylinder 41, and the support cylinder 82 is located on the side of the lower bearing plate 2 that does not contact the ground. The hydraulic servo cylinder 83 is arranged in the support cylinder 82, the hydraulic servo cylinder 83 is in contact with the ground, and the hydraulic rod of the hydraulic servo cylinder 83 is hinged to the upper inner wall of the support cylinder 82. When the spirit level 81 shows that it is not level, manually adjust the hydraulic servo cylinder 83 that is closest to the uneven position until the spirit level 81 shows that the lower bearing plate 2 is level.

[0021] like Figure 5 As shown, the locking mechanism 9 includes a rotating ring 91 and a clamping cylinder 92. The rotating ring 91 is fixed on the upper bearing plate 1, and the rotating ring 9 is arranged on the side of the upper bearing plate 1 facing the lower bearing plate 2, and is arranged concentrically with the upper bearing plate 1. The diameter of the rotating ring 91 is larger than the diameter of the slewing bearing 3. The clamping cylinder 92 is fixed on the lower bearing plate 2, and the clamping cylinder 92 is arranged on the arc where the rotating ring 91 is projected to the lower bearing plate 2, that is, the rotating ring 91 is located between the two clamping claws of the clamping cylinder 92. The signal output end of the level 81 is connected to the signal input end of the clamping claw cylinder 92. When the level 81 shows that the lower bearing plate 2 is not horizontal, the two clamping claws of the clamping claw cylinder 92 move relative to each other to clamp the rotating ring 91, so that the upper bearing plate 1 stops rotating.

[0022] Furthermore, the upper load-bearing plate 1 and the lower load-bearing plate 2 are both annular circular plate structures with a hollow structure in the middle, which can reduce their own weight. Among them, the upper load-bearing plate 1 is made of hard alloy aluminum, which can meet the support strength and reduce its own weight at the same time, and the upper load-bearing plate 1 is provided with four support holes 11 for hand-pushing the rotating device. The support holes 11 pass through the upper load-bearing plate 1 from top to bottom. When moving the rotating device, the person holds the support holes 11 and pushes the rotating device to move. The side of the lower load-bearing plate 2 that contacts the ground is provided with an anti-skid layer 6, and the anti-skid layer 6 can increase the friction between the lower load-bearing plate 2 and the ground and improve stability. Two electromagnets 5 are embedded in the upper load-bearing plate 1. When the flat plate 71 of the controllable seismic source vehicle 7 falls on the upper load-bearing plate 1, the electromagnet 5 is energized to generate magnetism, and mutually adsorbs with the flat plate 71 of the controllable seismic source vehicle 7, thereby increasing the stability of the connection between the upper load-bearing plate 1 and the controllable seismic source vehicle 7.

[0023] When using this embodiment, it is necessary to first carry the device to the bottom of the controllable source vehicle 7 that needs to turn around or turn. Before carrying, start the three cylinders 42 to extend the piston rods of the cylinders 42, driving the pulley 43 to pop out the installation cylinder 41, such as Figure 2As shown, the pulley 43 is in contact with the ground, the entire rotary device is supported and lifted off the ground, and then a person holds the support hole 11 on the upper load-bearing plate 1 by hand, and uses the rolling of the three pulleys 43 to push the rotary device forward, which greatly reduces the labor intensity of transportation. When the rotary device is carried to the edge of the controllable vibrator vehicle 7, it is inconvenient to apply force because a person cannot reach the position below the controllable vibrator vehicle 7. By pushing the rotary device with the pulley 43, it is convenient to quickly push the rotary device to the center of the controllable vibrator vehicle 7, saving time and effort. After finding the correct position for placing the slewing device, retract the piston rod of the air cylinder 42, drive the pulley 43 to be stored in the installation cylinder 41, and let the slewing device fall on the ground, so that the lower bearing plate 2 contacts the ground. At this time, observe the level 81 on the lower bearing plate 2. If it shows that the lower bearing plate 2 is level, proceed to the next step. If the level 82 shows that the lower bearing plate 2 is not level, adjust the hydraulic servo cylinder 83 closest to the uneven position to make the hydraulic rod of the hydraulic servo cylinder 83 rise or fall until the lower bearing plate 2 is level. Then, use the original cylinder structure of the controllable seismic source vehicle 7 to make the flat plate 71 of the controllable seismic source vehicle 7 fall on the upper bearing plate 1 (such as Figure 6 As shown in FIG. 1 ), continue to adjust the oil cylinder of the controllable vibrator vehicle, so that the controllable vibrator vehicle 7 is lifted upward with the slewing device as support, and the wheels are off the ground (as shown in FIG. 1 ). Figure 7 As shown), after stabilization, start the electromagnet 5, which generates magnetism when powered on, and adsorbs to the flat plate 71 of the controllable vibrator vehicle 7, increasing the binding force between the two. Finally, the controllable vibrator vehicle 7 is pushed manually. Since the resistance of the slewing bearing 3 is small, the controllable vibrator vehicle 7 can be easily pushed and rotate around the slewing bearing 3. During the rotation, the surrounding situation can be observed at any time to prevent collision with other obstacles. When the level 81 shows that the lower bearing plate 2 is not horizontal, the two clamping claws of the clamping claw cylinder 92 move relative to each other, clamping the rotating ring 91, stopping the upper bearing plate 1 from rotating, stopping the steering, adjusting the hydraulic servo cylinder 83 until it is horizontal, and continuing to complete the steering. After completing the U-turn or turning, start the oil cylinder on the controllable vibrator vehicle 7 to lower the controllable vibrator vehicle 7, the wheels fall on the ground, the flat plate 71 of the controllable vibrator vehicle 7 rises and separates from the upper load-bearing plate 1, adjust the hydraulic rod of the hydraulic servo cylinder 83, make the hydraulic servo cylinder 83 completely retracted into the support tube 82, then pop out the pulley 43 on the slewing device, and move the slewing device out.
