Detailed implementation mode

[0042] The technical solution of the present invention will be further described below, but the scope of protection claimed is not limited thereto.

[0043] Embodiment:

[0044] As Figures 1 to 22 shown, a vehicle-mounted lodging and lifting mechanism includes a lodging mechanism 1 and a lifting mechanism 5. The lodging mechanism 1 includes a base 31 and a lodging electric cylinder 9. The lifting mechanism 5 includes a lifting sleeve and a lifting electric cylinder 12. One end of the lodging electric cylinder 9 is connected to the base 31, and the other end of the lodging electric cylinder 9 is connected to the lifting sleeve. The lifting sleeve is connected to the base 31. The lifting electric cylinder 12 is respectively connected to the base 31 and the lifting sleeve.

[0045] The base 31 includes a bottom plate 35, side plates A 36, side plates B 37, and a mounting plate 38. The side plates A 36 are arranged on both sides of the bottom plate 35. The side plates B 37 are arranged on the bottom plate 35. The mounting plate 38 is arranged on the side plates B 37. A bearing seat hole 16 is arranged on the side plates A 36. A bearing and a rotating shaft 17 are arranged in the bearing seat hole 16. A proximity switch A 14 is arranged on the side of the side plate A 36 on one side of the bottom plate 35. A cushion plate 3 is arranged on the side plates B 37 to finely adjust the angle after the cylinder body is erected. The lodging electric cylinder 9 is connected to the middle of the mounting plate 38. Through holes are respectively opened on the side plates B 37 and the mounting plate 38, and can be connected to a vehicle-mounted turret or a vehicle-mounted mounting seat by screwing. The side plates B 37 and the mounting plate 38 form an L-shaped limiting seat and are arranged below the side of the wall of the first-stage cylinder 28 close to the lodging electric cylinder 9. The side plates A 36 are trapezoidal, and the bearing seat hole 16 is arranged on the lower side of the side plates A 36. The side plates B 37 are rectangular and are connected to the higher side of the side plates A 36.

[0046] On one side of the mounting plate 38, an electric push rod 4, a proximity switch B6, and a limit seat B8 are provided. The electric push rod 4 is connected to a bolt 7, and the bolt 7 is fixed by the limit seat B8. A push rod induction plate is arranged on the bolt 7. Two proximity switches B6 are arranged on one side of the bolt 7 and are fixed by a proximity switch mounting seat A. A buffer device 34 is arranged on the other side of the mounting plate 38.

[0047] The lifting sleeve includes a first-stage cylinder 28, a second-stage cylinder 29, and a third-stage cylinder 30. The first-stage cylinder 28, the second-stage cylinder 29, and the third-stage cylinder 30 are connected in sequence. The first-stage cylinder 28 is connected to the base 31 and the lodging electric cylinder 9. The first-stage cylinder 28, the second-stage cylinder 29, and the third-stage cylinder 30 are all rectangular structures with four sides. The lifting electric cylinder 12 is arranged inside the first-stage cylinder 28 and is fixedly connected to the bottom of the first-stage cylinder 28. A rotating shaft 17 is arranged between the lifting electric cylinder 12 and the wall of the first-stage cylinder 28. The rotating shaft 17 passes through both sides of the wall of the first-stage cylinder 28. On the outer side of the wall of the first-stage cylinder 28 on the same side as the proximity switch A14 and near the rotating shaft 17, two groups of induction bolts 15 are arranged. Each group of induction bolts 15 corresponds to two proximity switches A14 on the mounting seat respectively.

[0048] A cover plate A10 is arranged on the top of the first-stage cylinder 28. Two sequence locks A22 are arranged on the upper part of each side of the first-stage cylinder 28. A proximity switch C32 is arranged between two sequence locks A22 on the same side as the induction plate 27 on the outer wall of the first-stage cylinder 28. A guide block 18, a limit block 19, and a proximity switch D33 are arranged on the first-stage cylinder 28. A guide block 18 is arranged under each sequence lock A22. A limit block 19 is arranged between each guide block 18 and the sequence lock A22. The proximity switch D33 is installed on the right side of the limit block 19 on the same side as the proximity switch C32 and passes through the wall of the first-stage cylinder 28 and can detect the outer wall of the second-stage cylinder 29.

[0049] A cover plate B11 is arranged on the top of the second-stage cylinder 29. Two sequence locks B23 are arranged on each side of the second-stage cylinder 29. A limit hole A24 is opened under each sequence lock B23. A guide block 18 is arranged under each sequence lock B23. A limit block 19 is arranged between the guide block 18 and the sequence lock B23. Lower limit plates 21 are arranged on each surface of the lower part of the second-stage cylinder 29. An upper limit plate 20 is arranged on the upper side of the lower limit plate 21. A limit block 19 is arranged between the upper limit plate 20 and the lower limit plate 21. An induction hole 26 is opened on the right side of the upper limit plate 20 on the same side as the proximity switch D33, so that when the entire sleeve is lifted in place, the proximity switch D33 just corresponds to this induction hole 26.

[0050] The top of the three-stage cylinder 30 is provided with a cover plate C13, and each side of the three-stage cylinder 30 is provided with a lower limit plate 21, and the upper limit plate 20 is installed on the upper part of the lower limit plate 21. The upper limit plate 20 has two limit holes B25 on the upper part. The top of the lifting electric cylinder 12 is connected to the lower side of the cover plate C13, and the side of the cover plate C13 is connected to the three-stage cylinder 30. An induction plate 27 is provided on the side of the cover plate C13 in the same axial direction as the rotating shaft 17. The corresponding interface can be set on the cover plate C13 according to the load equipment.

[0051] The upper limit plate 20 has an inclined structure on the top and an L-shaped raised structure on the bottom; the lower limit plate 21 has an inclined structure on the bottom; the guide block 18 and the limit block 19 are both convex structures in the middle. The main function of the guide block 18 is to provide guidance and radial limiting for the walls of the secondary cylinder 29 and the tertiary cylinder 30 when the cylinder walls are extended and retracted. The lifting mechanism 5 will rub against the outer walls of the secondary cylinder 29 and the tertiary cylinder 30 when lifting and lowering. Therefore, the guide block 18 needs to be made of a material softer than the cylinder wall, and the height of the guide block 18 boss is adjusted to control the gap between the cylinders at each level. The upper limit plate 20, the lower limit plate 21 and the limit block 19 are used in conjunction with each other. When the cylinder wall is about to rise into place, the limit plate on one cylinder wall can radially position the cylinder wall by touching the upper limit block 19 of the other cylinder wall. The L-shaped structure of the upper limit plate 20 touches the limit block 19, thereby stopping the cylinder wall from moving upward and positioning the cylinder wall axially. When the cylinder wall is about to drop into place, the lower limit plate 21 can position the cylinder wall radially, and the cover plate at the top of a certain cylinder falls on the cover plate at the top of another cylinder at the lower part, so that the cylinder at the upper part stops moving downward, thus achieving axial positioning.

[0052] The buffer device 34 includes a top column 39, a nut 40, a buffer body 41 and an elastic member A42. The buffer body 41 is arranged on the mounting plate 38. The top column 39 extends into the buffer body 41 for sliding connection and passes through one side of the buffer body 41 and is connected to the nut 40. The elastic member A42 is arranged in the buffer body 41. One end of the elastic member A42 is connected to the top column 39, and the other end of the elastic member A42 is connected to the buffer body 41. The nut 40 is arranged on the side away from the lifting sleeve, and is used to buffer the impact and shaking caused by the collision with the pad 3 when the erection mechanism 5 rotates from the horizontal to the vertical state. The top of the inverted electric cylinder 9 is connected to the upper outer wall of the first-level cylinder 28.

[0053] The sequential lock A22 is provided with a slide groove 43, in which an elastic member B44 and a limiting ball 45 are provided. One end of the elastic member B44 is connected to the slide groove 43, and the other end of the elastic member B44 is connected to the limiting ball 45. The limiting ball 45 is a steel ball. The structure of the sequential lock B23 is the same as that of the sequential lock A22.

[0054] A stopper 19 is provided at the lower part of each side of the first-stage cylinder 28, and a stopper plate A2 is provided on the cylinder wall on the same side of the first-stage cylinder 28 and the pad 3.

[0055] The working principle of the lodging lifting mechanism is as follows:

[0056] In the lodging state, the lodging electric cylinder 9 is in the extended state. During operation, the lodging electric cylinder 9 contracts, and the erection mechanism 5 rotates around the rotating shaft 17. When it rotates to the vertical state, the first-stage cylinder 28 touches the cushion plate 3 on the base 31 and touches the buffer device 34 to reduce the impact with the base 31. At this time, a group of induction bolts 15 on the outer side of the wall of the first-stage cylinder 28 are sensed by the proximity switch A14 on the base 31, causing the lodging electric cylinder 9 to stop working. The electric push rod 4 is started, and the electric push rod 4 extends to push the pin 7 above the limit seat 8. At this time, the push rod induction plate on the pin 7 is sensed by the proximity switch B6 near the inner side, and the electric push rod 4 stops working. At this time, the limit seat B8 fixes the limit seat 8 and the base 31 through the pin 7, that is, the lifting mechanism 5 is fixed to the base 31. At this time, it becomes the low position state. In the low position state, the tops of the first-stage cylinder 28, the second-stage cylinder 29, and the third-stage cylinder 30 are approximately at the same height, that is, the first-stage cylinder 28 sleeves the second-stage cylinder 29, and the second-stage cylinder 29 sleeves the third-stage cylinder 30. At this time, the limit ball 45 of the sequence lock A22 of the first-stage cylinder 28 is stuck in the limit hole A24 of the second-stage cylinder 29.

[0057] When changing from the low position state to the high position state, the lifting electric cylinder 9 operates and extends. The lifting electric cylinder 9 drives the cover plate C13 to move upward, and the cover plate C13 drives the third-stage cylinder 30 to move upward. Because the limit ball 45 of the sequence lock A22 of the first-stage cylinder 28 is stuck in the limit hole A24 of the second-stage cylinder 29, only the third-stage cylinder 30 rises at this time. When the upper limit plate 20 of the third-stage cylinder 30 touches the limit block 19 on the upper part of the second-stage cylinder 29, it drives the limit block 19 to move upward, and the second-stage cylinder 29 rises upward. At this time, the thrust of the lifting electric cylinder 12 is used to move the limit ball 45 in the sequence lock A22 out of the limit hole A24 in the second-stage cylinder 29, and the limit ball 45 compresses the elastic member B44 and moves towards the sequence seat of the sequence lock A22, that is, the sequence lock A22 body, and as the second-stage cylinder 29 rises, the limit ball 45 rolls on the outer surface of the second-stage cylinder 29 under the thrust of the elastic member B44. When the upper limit plate 20 of the second-stage cylinder 29 touches the upper limit block 19 of the first-stage cylinder 28, at this time, the induction hole on the second-stage cylinder 29 corresponds exactly in front of the proximity switch D33, and the third-stage cylinder 30 is already entirely above the proximity switch D33. The state in front of the proximity switch D33 changes from sensing a metal state to not sensing a metal state, and a feedback signal is obtained to stop the movement of the lifting electric cylinder 12. At this time, the limit ball 45 of the sequence lock B23 just gets stuck in the limit plate B25 of the third-stage cylinder 30 through the elastic member B44, and the high position state is reached. The operation from the low position to the high position is completed.

[0058] When the high-level state changes to the low-level state, the retracting and lifting electric cylinder 12 contracts, and the lifting electric cylinder 12 drives the cover plate C13 to move downward. The cover plate C13 drives the three-stage cylinder 30 to move downward. At this time, since the limit ball 45 of the sequence lock B23 is stuck into the limit plate B25 of the three-stage cylinder 30, the three-stage cylinder 30 drives the entire two-stage cylinder 29 to move downward. When the two-stage cylinder 29 reaches the low level, the cover plate B11 presses on the cover plate A10, and the two-stage cylinder 29 stops moving. At this time, the limit ball 45 on the sequence lock A22 is pushed into the limit hole A24 under the thrust of the elastic member B44. Under the downward pulling force of the lifting electric cylinder 12, the three-stage cylinder 30 continues to move downward. Since the two-stage cylinder 29 stops moving, the limit ball 45 on the sequence lock B23 moves out of the limit plate B25, and the limit ball 45 rolls on the surface of the three-stage cylinder 30 under the thrust of the elastic member B44. When the cover plate C13 touches the cover plate B11, at this time, the induction plate 27 on the cover plate C13 is sensed by the proximity switch C32 installed at the top of the first-stage cylinder 28, and the lifting electric cylinder 12 stops moving, and the movement from the high-level state to the low-level state is completed.

[0059] When the lifting mechanism 5 lies down, first, the electric push rod 4 contracts, so that the bolt 7 is disengaged from the limit seat 8. When the push rod induction plate on the bolt 7 reaches the specified position, it is sensed by the proximity switch B6 on the outside, and the electric push rod 4 is unlocked. Then, the lying-down electric cylinder 9 extends, so that the lifting mechanism 5 rotates around the rotating shaft 17 to the horizontal position. At this time, another set of induction bolts 15 below the first-stage cylinder 28 is sensed by another set of corresponding proximity switches A14 on the base 31, and the lying-down electric cylinder 9 stops working, and the lying-down process is completed.

[0060] The lying-down and lifting mechanism of the present utility model can be fixed on the vehicle-mounted platform through the lying-down mechanism 1, and equipment such as a radar can be installed on the top of the lifting mechanism 5.
