Description

Technical Field

[0001] The present application relates to the field of ground penetrating radar, and in particular to an integrated vehicle-mounted electric lifting bracket for array ground penetrating radar. Background Art

[0002] The existing vehicle-mounted array ground-penetrating radar brackets are mainly divided into three categories: trailer type, suspension type and electric lifting type. The trailer type structure loads the array ground-penetrating radar on a special trailer and tows it forward with the vehicle. The travel speed is slow and reversing is difficult, which affects work efficiency. The suspension type structure suspends the array ground-penetrating radar as a whole on the trailer bar at the front or rear of the carrier vehicle. The travel speed is fast, but the height of the array radar from the ground cannot be quickly adjusted, and the work efficiency is also limited. The electric lifting type is also a suspension solution. On this basis, an electric lifting device is added. During detection work, the array radar is lifted to a suitable height from the ground; when the detection work is transferred, the array radar can be further lifted from the ground to improve the passability of the whole vehicle, ensure the transfer speed, and improve work efficiency.

[0003] With respect to the above-mentioned related technologies, when the system passes over speed bumps or encounters obstacles such as gravel during operation, and the array radar is too close to the ground, the array ground penetrating radar first contacts the ground obstacle, and the lower edge of the array ground penetrating radar in the forward direction frequently contacts the obstacle, causing collisions, thereby reducing the safety of the array ground penetrating radar and shortening the service life of the array ground penetrating radar. Utility Model Content

[0004] In order to improve the safety of the array ground penetrating radar during operation and increase its service life, the present application provides an integrated vehicle-mounted electric lifting bracket for the array ground penetrating radar.

[0005] The integrated vehicle-mounted electric lifting bracket for array ground penetrating radar provided in this application adopts the following technical solution:

[0006] An integrated vehicle-mounted electric lifting bracket for an array ground penetrating radar, comprising a support frame, the support frame is used to connect to a trailer bar; a lifting bracket, the lifting bracket is connected to the support frame and can move vertically along the support frame; a lifting component, the lifting component is arranged on the support frame and connected to the lifting bracket, driving the lifting bracket to perform lifting and lowering movements; a rotating arm, one end of the rotating arm is hinged to one side of the lifting bracket, and the end of the rotating arm away from the hinge point is bent toward the side away from the lifting bracket; a mounting hole is provided at the end of the rotating arm away from the hinge point, and the mounting hole is used to connect the rotating arm to the array ground penetrating radar; an anti-collision plate is provided at the end of the rotating arm away from the hinge point, the inclination direction of the anti-collision plate is consistent with the inclination direction at the bending position of the lifting bracket, and the anti-collision plate extends downward along the inclination direction; a tension rope, the tension rope is connected to the lifting bracket, and is used to tighten the array ground penetrating radar.

[0007] By adopting the above technical solution, the array ground penetrating radar is connected to the lifting bracket through the rotating arm, and the lifting assembly drives the lifting bracket to move up and down along the support frame, thereby realizing the lifting and lowering of the array ground penetrating radar. A collision plate is set at the lower edge of the array ground penetrating radar in the forward direction. When the system passes through a speed bump or encounters obstacles such as gravel during operation, and the array radar is too close to the ground, the collision plate first contacts the ground obstacle. The contact between the collision plate and the obstacle prevents the array ground penetrating radar from directly colliding with the obstacle, thereby improving the safety of the array ground penetrating radar and extending the service life of the array ground penetrating radar.

[0008] Optionally, the lifting assembly includes a lead screw and four connecting rods connected end to end, the connecting rod is provided with a hinge shaft, and the four connecting rods are hinged to each other through the hinge shaft to form a parallelogram structure; the relative hinge shafts of the four connecting rods are hinged to the lifting bracket and the support frame respectively; the lead screw is connected to the other two hinge shafts, and the rotation of the lead screw can drive the four connecting rods to move, thereby realizing the movement of the lifting bracket relative to the support frame.

[0009] By adopting the above technical solution, when the lead screw in the lifting assembly rotates, it can drive the parallelogram structure composed of four connecting rods to deform, thereby driving the lifting bracket to move vertically along the support frame. This lifting assembly has a simple structure and stable lifting, and can accurately lift the lifting bracket, rotating arm and array ground penetrating radar to a suitable height to adapt to different working scenarios.

[0010] Optionally, the lifting bracket is provided with a limit sliding block, and the support frame is provided with a vertical sliding groove at a position corresponding to the limit sliding block, the limit sliding block can move vertically in the sliding groove, and the limit sliding block can abut against the end wall of the sliding groove.

[0011] By adopting the above technical solution, the limit slider on the lifting bracket moves vertically in the slide groove of the support frame to guide the lifting bracket, making the lifting movement of the lifting bracket more stable. At the same time, when the limit slider abuts against the end wall of the slide groove, it can limit the lifting position of the lifting bracket to prevent the lifting bracket from leaving the support frame, thereby improving the stability and reliability of the system during operation.

[0012] Optionally, a tensioning pin is provided at a hinged position between the lifting bracket and the rotating arm, and the rotating arm is hinged to the lifting bracket via the tensioning pin.

[0013] By adopting the above technical solution, the tightening pin realizes the detachable connection between the lifting bracket and the rotating arm. The detachable connection method allows the lifting bracket and the rotating arm to be detached, which can reduce the overall transportation volume of the electric lifting bracket and make the transportation of the electric lifting bracket more convenient.

[0014] Optionally, a connecting block is provided on a side of the support frame away from the rotating arm, and the connecting block is provided with a locking assembly, and the locking assembly can lock the connecting block and the trailer bar.

[0015] By adopting the above technical solution, the locking assembly plays a key role in fixing and stabilizing the connection block and the trailer bar. Its main purpose is to ensure that the connection between the connection block and the trailer bar is firm and reliable to prevent loosening or falling off during driving or working.

[0016] Optionally, the locking assembly includes a locking slider, the locking slider abuts against the end of the connecting block away from the supporting frame, the end surfaces of the locking slider and the connecting block that contact each other are both inclined surfaces, and the inclined surfaces are inclined from top to bottom toward the end away from the supporting frame; the locking slider is provided with a locking bolt, the locking bolt passes through the connecting block and the supporting frame, and is threadedly connected with a locking nut, and with the cooperation of the locking bolt and the locking nut, the locking slider slides along its inclined surface in the vertical direction relative to the connecting block, and presses against the inner wall of the square opening of the trailer bar to achieve locking.

[0017] By adopting the above technical solution, the locking slider of the locking assembly contacts the connecting block through the inclined surface, so that under the cooperation of the locking bolt and the locking nut, the locking slider can slide relative to the connecting block in the vertical direction along the inclined surface. When the locking bolt is tightened, the locking slider slides upward along the inclined surface, and the upper end surface of the locking slider and the lower end surface of the connecting block jointly support the inner wall of the square opening of the trailer bar, thereby achieving locking with the trailer bar. This locking method is simple and effective, and can quickly and stably connect the support frame to the trailer bar.

[0018] Optionally, the locking assembly includes a locking pin and a locking rod, the locking pin passing through the top of the connecting block, and the locking pin can slide vertically; the locking rod abuts against the locking pin inside the connecting block, and the abutting surfaces of the locking rod and the locking pin are both inclined surfaces, and the inclined surfaces are inclined from top to bottom toward the direction approaching the supporting frame; under the action of the locking rod, the locking pin is inserted into the square opening of the trailer bar to achieve locking; the locking rod is provided with a spring, and the spring applies force to the locking rod to approach the supporting frame.

[0019] By adopting the above technical solution, this locking method has a simple structure and is easy to operate, and can quickly and effectively achieve the locking of the support frame and the trailer bar. The design of the spring and the inclined surface enables the locking pin to be stably inserted into the square opening of the trailer bar, thereby improving the stability and reliability of the locking.

[0020] Optionally, the locking rod has a support portion at a position corresponding to the inclined surface, the support portion is plate-shaped, the support portion includes a rotating portion on a side close to the support frame, the rotating portion is cylindrical, and the support portion is smoothly transitionally connected to the rotating portion.

[0021] By adopting the above technical solution, when it is necessary to unlock the connection between the support frame and the trailer bar, by pushing and rotating the knob, the locking latch can smoothly slide from the inclined surface of the support part to the cylindrical part of the rotating part. Since the rotating part is cylindrical, when the knob is rotated, the locking latch will not prevent the rotation of the locking rod. After the knob is released after rotation, the locking latch abuts against the flat surface of the support part, thereby releasing the trailer bar and realizing the rapid separation of the support frame and the trailer bar.

[0022] In summary, the present application includes at least one of the following beneficial technical effects:

[0023] 1. When the system is operating, if it passes a speed bump or encounters obstacles such as gravel, the anti-collision plate will first contact the ground obstacle, causing the array ground penetrating radar to swing upward and backward to avoid the obstacle. This design can protect the radar body from damage due to contact with obstacles, thereby extending the service life of the radar body;

[0024] 2. When the collision plate contacts an obstacle, the rotating arm will swing upward and backward around the hinge point, and the array radar will also swing under the drive of the rotating arm. Under the action of the tension rope, the radar body will also rotate relative to the rotating arm, so that the angle between the radar body and the ground is increased and kept as horizontal as possible. This design improves the accuracy of the radar body and ensures the accuracy of data collection;

[0025] 3. The connection block and the locking slider can ensure the stability of the connection between the electric lifting bracket and the trailer bar, thereby ensuring the overall reliability of the system during operation, improving the stability of the overall system, and ensuring the smooth completion of the task.

In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "example", "specific example", or "some examples" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present application. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in an appropriate manner in any one or more embodiments or examples.

[0037] Embodiment 1, this application embodiment discloses an integrated vehicle-mounted electric lifting bracket for array ground penetrating radar. Figure 1 and Figure 2 An integrated vehicle-mounted electric lifting bracket for array ground penetrating radar includes a support frame 1 and a lifting bracket 2. The support frame 1 is used to connect with a trailer bar 91. The lifting bracket 2 is connected to the support frame 1. The support frame 1 and the lifting bracket 2 are jointly provided with a lifting assembly 3. The lifting assembly 3 drives the lifting bracket 2 to perform lifting movement along the support frame 1 to realize the lifting function of the electric lifting bracket. A rotating arm 4 is provided on one side of the lifting bracket 2. One end of the rotating arm 4 is hinged to the lifting bracket 2. The end of the rotating arm 4 away from the hinge point is bent toward the side away from the lifting bracket 2; the end of the rotating arm 4 away from the hinge point is provided with a mounting hole, and the mounting hole is used to realize the connection between the rotating arm 4 and the array ground penetrating radar 9; the end of the rotating arm 4 away from the hinge point is provided with an anti-collision plate 5, and the inclination direction of the anti-collision plate 5 is consistent with the inclination direction at the bending position of the lifting bracket 2. The anti-collision plate 5 extends downward along the inclination direction to the position of the array ground penetrating radar 9. A tension rope 6 is provided at a position above the lifting bracket 2 corresponding to the rotating arm 4 . The tension rope 6 is made of a material without elasticity or with low elasticity. The tension rope 6 tightens the array ground penetrating radar 9 .

[0038] One end of the array ground penetrating radar 9 is hinged to the rotating arm 4, and the other end is tightened by the tension rope 6. The array ground penetrating radar 9 remains horizontal under the action of the tension rope 6. The array ground penetrating radar 9 is lifted and lowered with the lifting bracket 2 under the action of the lifting component 3. The electric lifting bracket can lower the bracket installation height when installing the array radar, which is convenient for installation. During detection work, the array radar is lifted to a suitable height above the ground; when the detection work is transferred, the height of the array radar above the ground can be further raised to improve the passability of the whole vehicle and ensure the transfer speed. When the system passes through speed bumps or encounters obstacles such as gravel during operation, and the array radar is too close to the ground, the anti-collision plate 5 first contacts the ground obstacle, so that the array ground penetrating radar 9 is forced to swing upward and backward to avoid obstacles, thereby protecting the safety of the radar body and increasing the service life of the radar body.

[0039] When the anti-collision plate 5 contacts the obstacle, the rotating arm 4 will swing upward and backward around the hinge point. At this time, the array ground penetrating radar 9 will also swing driven by the rotating arm 4. At the same time, the array ground penetrating radar 9 will rotate relative to the rotating arm 4 under the action of the tension rope 6. The angle between the radar body and the rotating arm 4 increases, ensuring that the radar body remains as level as possible with the ground, thereby improving the accuracy of the radar body.

[0040] Reference Figure 3 The support frame 1 includes two vertical frames and two horizontal transverse frames. The two transverse frames are located between the two vertical frames. The two ends of the two transverse frames are fixedly connected to the two vertical frames through connecting pieces.

[0041] Reference Figure 3 and Figure 4 The lifting bracket 2 includes two vertical brackets and a horizontal cross frame. The cross frame is located between the two brackets, and the two ends of the cross frame are respectively fixedly connected to the top of the two brackets through connectors. The support frame 1 is located between the two brackets, and the two vertical frames are connected to the opposite sides of the two brackets on the side away from each other. A vertical slide 11 is provided on the side away from each other of the two vertical frames. The two brackets are fixedly connected to the position of the slide 11 with a limit slider 21. The limit slider 21 slides vertically in the slide 11, so that the lifting bracket 2 is vertically lifted relative to the support frame 1.

[0042] Reference Figure 3 The slide groove 11 is not connected to the upper and lower end surfaces of the vertical frame. The limit slider 21 slides in the slide groove 11 and can abut against the end wall of the slide groove 11, thereby limiting the maximum height of the lifting bracket 2 to prevent the lifting bracket 2 from separating from the supporting frame 1.

[0043] Reference Figure 2The lifting assembly 3 includes a lead screw 32 and four connecting rods 31 connected end to end. The connecting rod 31 is hinged with a hinge shaft. The four connecting rods 31 are of equal length and are hinged to each other through the hinge shaft to form a diamond structure. The hinge shafts relative to the four connecting rods 31 are respectively hinged to the cross frame and the cross frame located above, and the lead screw 32 is connected to the other two hinge shafts. The lead screw 32 is provided with a threaded section and a smooth section, one of the hinge shafts is threadedly connected to the threaded section, and the smooth section of the lead screw 32 is penetrated by another hinge shaft. An electric jack 33 is provided at one end of the lead screw 32 that is set as the smooth section. The electric jack 33 is fixedly connected to the hinge shaft through which the lead screw 32 is penetrated. The electric jack 33 drives the lead screw 32 to rotate, and the hinge shaft connected to the threaded section moves toward or away from the electric jack 33, so that the two hinge shafts located above and below move in a direction close to or away from each other, thereby realizing the lifting movement of the lifting bracket 2 relative to the support frame 1.

[0044] Further, see Figure 4 and Figure 5 A tensioning pin 41 is provided at the hinged position between the lifting bracket 2 and the rotating arm 4, and the rotating arm 4 is hinged to the lifting bracket 2 through the tensioning pin 41. Releasing the tensioning pin 41 can realize the detachable connection between the lifting bracket 2 and the rotating arm 4; the anti-collision plate 5 is fixed with a mounting portion, and the mounting portion is sleeved at the position of the corresponding mounting hole on the outside of the rotating arm 4. The anti-collision plate 5 is provided with a mounting pin 51, and the mounting pin 51 passes through the mounting portion and the mounting hole to realize the detachable connection between the anti-collision plate 5 and the rotating arm 4. The detachable connection method can reduce the overall transportation volume of the electric lifting bracket, making the electric lifting bracket more convenient to transport.

[0045] Reference Figure 2 A connecting block 12 is fixedly connected to the side of the lower horizontal frame away from the rotating arm 4 by bolts. The connecting block 12 is provided with a locking assembly 7. The locking assembly 7 locks the connecting block 12 and the trailer bar 91 to achieve a stable connection between the electric lifting bracket and the trailer bar 91.

[0046] Reference Figure 2The locking assembly 7 includes a locking slider 71, the locking slider 71 abuts against the end of the connecting block 12 away from the supporting frame 1, and the end surfaces of the locking slider 71 and the connecting block 12 that contact each other are both inclined surfaces, and the inclined surfaces are inclined from top to bottom toward the end away from the supporting frame 1. The locking slider 71 is fixed with a locking bolt 72, and the locking bolt 72 horizontally penetrates the connecting block 12 and the cross frame. The locking bolt 72 is threadedly connected with a locking nut, and the locking nut can abut against the cross frame. The locking slider 71 is used in conjunction with the connecting block 12 and the locking nut, and is inserted into the square opening of the trailer bar 91 together with the connecting block 12, and then the locking nut is tightened, and the locking slider 71 will slide relative to the connecting block 12, and stagger in the vertical direction along its inclined surface, and press against the inner wall of the square opening of the trailer bar 91, so as to play a locking role.

[0047] Further, see Figure 2 and Figure 3 The connecting block 12 is a hollow square tube structure, and a waist groove 13 for the locking bolt 72 to slide is opened at the position of the horizontal frame corresponding to the locking bolt 72, so as to facilitate the locking bolt 72 to slide in the vertical direction with the locking slider 71.

[0048] Reference Figure 1 and Figure 5 A front protective plate 8 is connected to the side of the rotating arm 4 away from the lifting bracket 2 by bolts, and a rear protective plate 81 is connected to the position of the lifting component 3 corresponding to the side of the supporting frame 1 away from the rotating arm 4 by bolts. The front protective plate 8 and the rear protective plate 81 jointly protect the lifting component 3 to reduce the entry of foreign matter into the position of the lifting component 3 and affect the lifting of the lifting bracket 2.

[0049] The implementation principle of the integrated vehicle-mounted electric lifting bracket for array ground penetrating radar in Example 1 of the present application is as follows: the electric lifting bracket can lower the bracket installation height when installing the array radar, which is convenient for installation. When the electric lifting bracket is connected to the trailer bar 91, the locking slider 71 and the connecting block 12 are inserted into the square opening of the trailer bar 91 together, and then the locking nut is tightened. The locking slider 71 will slide relative to the connecting block 12, and stagger in the vertical direction along its inclined surface, and support the inner wall of the square opening of the trailer bar 91 to play a locking role. During the detection work, the electric jack 33 is controlled to work and the array radar is lifted to a suitable height above the ground; when the detection work is transferred, the height of the array radar above the ground can be further increased to improve the passability of the whole vehicle and ensure the transfer speed. When the system passes through a speed bump or encounters obstacles such as gravel during operation, and the array radar is too close to the ground, the anti-collision plate 5 first contacts the ground obstacle, so that the array ground penetrating radar 9 is forced to swing upward and backward to avoid obstacles, thereby protecting the safety of the radar body and improving the service life of the radar body. When the anti-collision plate 5 contacts the obstacle, the rotating arm 4 will swing upward and backward around the hinge point. At this time, the array ground penetrating radar 9 will also swing driven by the rotating arm 4. At the same time, the array ground penetrating radar 9 will rotate relative to the rotating arm 4 under the action of the tension rope 6. The angle between the radar body and the rotating arm 4 increases, ensuring that the radar body remains as level as possible with the ground, thereby improving the accuracy of the radar body.

[0050] Embodiment 2 is different from Embodiment 1 in that, referring to Figure 6 The locking assembly 7 includes a locking pin 73 and a locking rod 74. The locking pin 73 and the locking rod 74 are arranged in an L shape. The locking rod 74 is arranged horizontally. The locking rod 74 is sequentially passed through one end of the horizontal frame connecting block 12 at the position corresponding to the connecting block 12, and abuts against the locking pin 73 inside the connecting block 12. The locking pin 73 passes through the top of the connecting block 12, and the locking pin 73 can slide vertically. The abutting surfaces of the locking rod 74 and the locking pin 73 are both inclined surfaces, and the inclined surfaces are inclined from top to bottom toward the direction close to the supporting frame 1. Under the action of the locking rod 74, the locking pin 73 can be inserted into the square opening of the vertical part of the trailer bar 91 to achieve locking.

[0051] Further, see Figure 6 The connecting block 12 is a hollow square tube structure. The end of the connecting block 12 away from the supporting frame 1 is closed. The end of the locking rod 74 away from the supporting frame 1 is fixed with a spring 75. The spring 75 is rotatably connected to the inner wall of the end of the connecting block 12 away from the supporting frame 1. The spring 75 applies force to the locking rod 74 to approach the supporting frame 1.

[0052] Further, see Figure 6 and Figure 7The position of the locking rod 74 corresponding to the inclined surface is a support portion 741, the support portion 741 is in the shape of a plate, the support portion 741 near the support frame 1 includes a rotating portion 742, the rotating portion 742 is cylindrical, and the support portion 741 is smoothly connected to the rotating portion 742. A straight-line knob 76 is fixedly connected to the end of the rotating portion 742 away from the support portion 741, and the support portion 741 is horizontally arranged when the knob 76 is horizontal. The smooth transition setting can ensure that the locking pin 73 can slide more smoothly on the surface of the locking rod 74.

[0053] Further, see Figure 6 A support frame 121 is fixedly connected to the inner wall of the connecting block 12, and the rotating portion 742 passes through the support frame 121. When the locking pin 73 is locked, the support portion 741 abuts against the support frame 121 under the action of the spring 75, thereby limiting the support portion 741 from continuing to move toward the direction of approaching the support frame 1, ensuring that the locking pin 73 will not be separated from the locking rod 74.

[0054] The implementation principle of the integrated vehicle-mounted electric lifting bracket for array ground penetrating radar in Example 2 of the present application is as follows: when the electric lifting bracket is connected to the trailer bar 91, the knob 76 is pushed, and the locking pin 73 drops under the action of its own gravity. At this time, the connecting block 12 is inserted into the square opening of the trailer bar 91, and the knob 76 is released. The locking pin 73 moves upward under the action of the inclined surface of the locking rod 74 until the locking pin 73 is inserted into the square opening of the vertical part of the trailer bar 91. At this time, the side wall of the locking pin 73 abuts against the inner wall of the trailer bar 91 to achieve locking. When it is necessary to separate the electric lifting bracket from the trailer bar 91, the knob 76 is pushed, and the locking pin 73 drops under the action of its own gravity and slides from the supporting portion 741 of the locking rod 74 to the rotating portion 742. At this time, the knob 76 is rotated 90° while being pushed, and the knob 76 is released. The locking pin 73 abuts against the flat surface of the supporting portion 741. At this time, since the flat surface cannot push the locking pin 73 to move upward, the locking pin 73 releases the trailer bar 91, thereby realizing the separation of the electric lifting bracket from the trailer bar 91.

[0055] The embodiment of the present application has the effect of improving the safety of the array ground penetrating radar 9 during operation and increasing its service life.

[0056] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
