DETAILED DESCRIPTION

[0029] In order to explain the technical content, the purpose and the effect of the present application in detail, the following will be described in combination with the embodiments and the accompanying drawings.

[0030] It should be noted that the conventional working platform usually adopts a four-point leveling mechanism, and each point adopts a cylinder driving link. In this structure, when the cylinder is leveled, the cylinder needs to be displaced relative to the base 2 to realize leveling because the cylinder is rigidly connected to the base 2, and the hinged points of the cylinder and the platform bracket bottom need to be displaced to realize leveling. The reason is that in the same radial plane, both ends of the two cylinders are hinged, and the two cylinders and the base and the table need to form a trapezoidal arrangement, and cannot adopt a rectangular arrangement, otherwise it will be unstable. When a rectangular arrangement is adopted, the bottom of the cylinder in the same radial plane needs to be rigidly fixed on the base. At this time, if the other end of the two cylinders is hinged to the table, the entire four-link structure is over-constrained, and the degree of freedom is 0, that is, the pure hinge cannot realize leveling. At the same time, the four cylinders of the four-point leveling mechanism have poor correlation, and it is difficult to control synchronously. In order to solve this problem, the present application proposes:

[0031] Please refer to Figure 1 and Figure 2 A hilly and mountainous land working platform leveling system, comprising a leveling mechanism 1 and a base 2.

[0032] The leveling mechanism 1 comprises a leveling bracket 11, a leveling link 12, a screw rod 13 and a leveling assembly 14. The leveling link 12 is arranged below the leveling bracket 11 and connected with the leveling bracket 11. The leveling assembly 14 is movably connected with both ends of the leveling link 12 in the length direction. The screw rod 13 is in transmission connection with the leveling assembly 14 and is used to drive the leveling assembly 14 to control the included angle between the leveling link 12 and the horizontal plane.

[0033] The base 2 is connected with the leveling assembly 14. The base 2 is provided with a connecting assembly 21 above. The connecting assembly 21 is hinged with both ends of the leveling bracket 11.

[0034] It can be understood that, due to the large change in terrain in hilly environment, the plane where the base is located is often in an inclined state (i.e. there is an angle with the horizontal plane), in order to maintain balance, the leveling screw rod is acted on by the leveling assembly, so that the leveling screw rod is parallel to the horizontal plane and is not affected by the terrain, as follows:

[0035] By setting the leveling assembly 14 in movable connection with the leveling connecting rod 12, and using the screw rod 13 to drive and control the leveling assembly 14, in the process of controlling the movement of the leveling assembly 14 by the screw rod 13, the leveling connecting rod 12 is gradually parallel to the horizontal plane, so that the leveling bracket 11 connected with the leveling connecting rod 12 is in an ideal state, for adapting to different inclined angles of slopes in hilly terrain; at the same time, the connecting rod structure is used to replace the traditional oil cylinder mechanism, reducing the space occupied by the device, facilitating processing and maintenance, especially suitable for small carrying machines to level in areas with large changes in terrain, and the connecting rod mechanism is used to drive leveling, because the connecting rod transmission process is simple, the response speed is better than that of the oil cylinder transmission, and the operation efficiency of the device is improved.

[0036] Please refer to Figure 1 , 2 , 5 and 6, in some embodiments, the leveling assembly 14 includes a slide rail 141 and two symmetrically arranged first scissors 142;

[0037] The first scissors 142 include two support arms 1421 and a first transmission part 1422, the two support arms 1421 are hinged by a first hinge part 1423, and the first hinge parts 1423 of the two scissors are movably connected with the two ends of the leveling connecting rod 12 in the length direction;

[0038] The two support arms 1421 are provided with a second hinge part 1424 at the end away from the first hinge part 1423; the second hinge parts 1424 of the two support arms 1421 away from each other in the two first scissors 142 are fixedly connected with the base 2, the second hinge parts 1424 of the two support arms 1421 close to each other in the two first scissors 142 are fixedly connected with the first transmission part 1422, the two first transmission parts 1422 are transmissionally connected with the two ends of the screw rod 13 in the length direction, the first transmission part 1422 is slidably connected with the slide rail 141, and the slide rail 141 is fixedly connected with the base 2.

[0039] As can be seen from the above description, the first scissors 142 are movably connected with the two ends of the leveling link 12 respectively, one of the two support arms 1421 of the first scissors 142 is hinged with the base 2, the other is connected with the first transmission part 1422 arranged on the slide rail 141, and the first transmission part 1422 is drivingly connected with the lead screw 13; under the driving of the lead screw 13, the first transmission part 1422 will slide in the slide rail 141, thereby dragging the support arm 1421 connected with the first transmission part 1422 to swing, and the height of the first hinge part 1423 connected with the leveling link 12 of the first scissors 142 changes in the process of swinging of the support arm 1421, since the two ends of the first scissors 142 in the length direction of the leveling link 12 are movably connected, i.e. the two ends of the leveling link 12 swing in the height direction according to the above principle, thereby adjusting the included angle between the leveling link 12 and the horizontal plane, so that the leveling link 12 is finally parallel to the horizontal plane, thereby keeping the leveling bracket 11 in the ideal position.

[0040] In addition, since the lead screw 13 is drivingly connected with the transmission parts of the two first scissors 142 respectively, i.e. one lead screw 13 rotates to control the two first transmission parts 1422 to operate cooperatively at the same time, thereby making the swinging processes of the two scissors have a chain effect, instead of adjusting based on the parameters of the two oil cylinders respectively, the control difficulty is reduced, and the device is more stable during leveling. Preferably, the first transmission part 1422 is a transmission nut, the specifications of which match the specifications of the lead screw 13, and the shape of the slide rail 141 matches the shape of the conventional nut.

[0041] Specifically, one end of the leveling link 12 in the length direction is provided with a sliding groove 121, and at least one first hinge part 1423 is slidably connected with the sliding groove 121. That is, the sliding groove 121 is arranged on the leveling link 12, and at least one first hinge part 1423 is arranged in the sliding groove 121, so that the phenomenon of over-constraint is avoided in the above transmission process, and the stability of the device is improved; preferably, the other first hinge part 1423 is hinged with the other end of the leveling link 12.

[0042] Please refer to Figure 3 and Figure 4 In some embodiments, the system further comprises a lifting mechanism 3; the lifting mechanism 3 comprises a working platform 31 and a lifting assembly 32, the lifting assembly 32 is arranged above the leveling bracket 11 and movably connected with the leveling bracket 11, the lifting assembly 32 is movably connected with the working platform 31, and the lifting assembly 32 is used to control the working platform 31 to ascend and descend in the vertical direction.

[0043] From the above description, the lifting mechanism 3 is arranged in the device, which is located above the leveling bracket 11, meets the leveling function, at the same time, the lifting function is arranged, the working platform reaches the required height, and the universality of the device is enhanced.

[0044] Specifically, the lifting assembly 32 comprises a second transmission part 321 and two symmetrically arranged second scissors 322, the second scissors 322 are provided with a power arm 3221 and an auxiliary arm 3222, the power arm 3221 and the auxiliary arm 3222 are hinged to each other, one end of the power arm 3221 and the auxiliary arm 3222 in the length direction is hinged to the leveling bracket 11, and the other end of the power arm 3221 and the auxiliary arm 3222 in the length direction is movably connected to the working platform 31.

[0045] The second transmission part 321 is in transmission connection with the power arm 3221, and is used for controlling the power arm 3221 to swing around the hinge point of the leveling bracket 11, and the swinging plane of the power arm 3221 is arranged at an angle with the length direction of the leveling connecting rod 12.

[0046] From the above description, the second scissors 322 are arranged to form the lifting assembly 32, the principle of which is to control the lifting by using the power arm 3221 and the auxiliary arm 3222 in the second scissors 322 after being hinged, wherein the second transmission part 321 controls the power arm 3221 to swing around the hinge point of the leveling bracket 11, and the auxiliary arm 3222 is unfolded during the swinging of the power arm 3221, so as to lift the working platform 31 and realize the lifting. At the same time, the swinging plane of the power arm 3221 is arranged at an angle with the length direction of the leveling connecting rod 12, so as to avoid that the swinging plane is parallel to the leveling connecting rod 12, if the two are parallel, the adjustment directions of the two will coincide, so that the working platform can only be leveled in a certain plane and cannot be leveled stably in space, that is, the working platform can only be leveled in a plane along an axis (for example, the X axis), and cannot be adjusted in a plane along the Y axis.

[0047] Preferably, the second transmission part 321 comprises a transmission arm and a driving motor, both ends of the transmission arm in the length direction are connected with the power arm 3221 respectively, and the driving motor is used for controlling the transmission arm to adjust the position in the height direction. That is, by arranging the transmission arm, the two second scissors 322 are controlled in series, and the stability of the lifting process of the device is enhanced.

[0048] Specifically, the power arm 3221 is provided with an extension arm 3223 and a leveling motor 3224 at one end close to the working platform 31, the extension arm 3223 is movably connected with the working platform 31, and the leveling motor 3224 is used to control the extension length of the extension arm 3223. After reaching the required height under the driving of the second transmission member, inclination may occur in another direction due to the scissor structure or the terrain. In order to solve this problem, the power arm 3221 is provided with the extension arm 3223 and the leveling motor 3224 at one end close to the working platform 31, and the extension length of the extension arm 3223 is controlled by the leveling motor 3224 to solve the inclination problem in a certain direction.

[0049] Preferably, the swing plane of the power arm 3221 is perpendicular to the length direction of the leveling connecting rod 12, and the beneficial effect of this arrangement is that the working platform 31 can be leveled in two perpendicular planes in a spatial orthogonal coordinate system, for example, the leveling connecting rod 12 drives the leveling bracket 11 to level in the left-right (relative) direction, and the extension arm 3223 and the leveling motor 3224 on the power arm 3221 drive the working platform 31 to level in the front-back (relative) direction, thereby adapting to different terrains and completing adjustment at any angle.

[0050] Preferably, the system further comprises an angle sensor for detecting the inclination angles of the working platform 31 relative to the X-axis and Y-axis of the horizontal plane.

[0051] As can be seen from the above description, the inclination angles of the two axes are detected by the angle sensor, and subsequent leveling is performed according to the inclination angles of the two axes by the first scissor member 142 and the second scissor member 322, thereby providing a reference for leveling and realizing the automation of the leveling of the device. Specifically, the angle sensor has two, which are installed at the middle position of the leveling bracket 11 below the working platform 31, i.e., at the center of the device to detect the inclination angle, thereby improving the detection efficiency and accuracy.

[0052] In some embodiments, the system further comprises a crawler walking mechanism 4 connected with the base 2, and the crawler walking mechanism 4 is used to control the movement of the system. Specifically, the crawler walking mechanism 4 comprises a walking motor, a driving wheel, a crawler belt, and a lithium battery pack. The use of the crawler walking lifting device improves the stability and climbing ability of the device in hilly terrain and improves the versatility of the device.

[0053] In some embodiments, the connecting assembly 21 is a symmetrically arranged connecting plate parallel to the length direction of the leveling link 12, and the connecting plate, the base 2 and the leveling bracket 11 enclose a containing space of the leveling assembly 14. The connecting plate is hinged with the leveling bracket, so that a space between the base and the leveling bracket is left by the height of the connecting plate, and the space is used for containing the leveling assembly, so that the leveling assembly is more stable in leveling effect with the leveling bracket, and meanwhile, the space occupation of the device in the system is reduced, and the space utilization is improved.

[0054] In some embodiments, the system further comprises a control unit used at least for driving the lead screw 13 to adjust the levelness of the leveling bracket 11 (left-right leveling unit). Figure 6 Preferably, the control unit also controls the driving motor to control the extension length of the extension arm 3223 (front-rear leveling unit), so as to level the device in two planes; and the control unit also controls the lifting height of the lifting mechanism 3 (lifting mechanism unit).

[0055] In summary, the leveling system and method suitable for the operation platform in hilly areas provided by the utility model effectively solve the problems of the traditional four-point leveling mechanism, such as synchronization control difficulty, over-constraint, insufficient degree of freedom and instability, and significantly improve the operation efficiency, applicability and stability of the device.

Compared with the traditional oil cylinder leveling mechanism, the leveling process of the link transmission is more concise, the response speed is faster, and the operation efficiency of the device is improved.

[0059] (2) Enhanced stability

[0060] The first scissors member is movably connected with the leveling link, the lead screw drives the first transmission part to realize the sliding of the sliding rail, drives the scissors member to swing, and adjusts the inclination angle of the leveling link, so that the over-constraint phenomenon is avoided. Meanwhile, the lead screw linkage controls two scissors members, realizes the interlocking movement in the leveling process, reduces the synchronization control difficulty in the adjustment process, and improves the leveling stability.

[0061] (3) Reduced space occupation

[0062] Adopting connecting rod structure to replace oil cylinder mechanism, simplifying structure design, reducing overall size of device, optimizing space utilization, facilitating processing and maintenance, especially suitable for small carrying machinery with complex terrain and limited space.

[0063] (4) Multi-axis leveling capability

[0064] The swing plane of the power arm and the leveling connecting rod is perpendicular to the swing plane of the leveling connecting rod, so that the device can be leveled in two perpendicular planes of the space rectangular coordinate system, thereby adapting to complex terrain changes, completing space adjustment of any angle, and meeting different application scene requirements.

[0065] (5) Inclination automatic detection and secondary leveling

[0066] The device is equipped with two angle sensors to monitor the X-axis and Y-axis inclination angles of the working platform relative to the horizontal plane in real time, and the control unit is used to drive the leveling and lifting mechanism to complete automatic leveling. In view of the secondary horizontal deviation caused by the scissor structure and mechanical stress deformation, the secondary leveling function is used to ensure that the working platform always maintains a horizontal state, thereby improving the working precision.

[0067] The above is only an embodiment of the present application, and does not limit the patent range of the present application, and any equivalent transformation or direct or indirect application in related technical fields based on the content of the present application is also included in the patent protection range of the present application.
