Description

Technical Field

[0001] This invention belongs to the field of engineering vehicle technology, and particularly relates to a mounting platform, an engineering vehicle thereof, and a method for its operation. Background Technology

[0002] In related technologies, engineering vehicles require specially designed mounting platforms to carry specialized equipment and perform tasks such as lifting and unloading. During operation, the mounting platform needs to be raised by lifting the rocker arm to elevate it, while simultaneously rotating in the opposite direction to maintain its level.

[0003] However, once the rocker arm is raised to its position, the hydraulic or pneumatic cylinders driving its rotation are insufficient to maintain the platform's level. Manual installation of a pin at the connection between the platform and the rocker arm is necessary for auxiliary positioning, posing a safety risk. Furthermore, the pin's positioning angle is limited and may not perfectly align with the rocker arm's raised angle. Therefore, after inserting the pin, the rocker arm height must be fine-tuned to secure it, making the operation cumbersome.

[0004] Therefore, there is an urgent need to design a mounting platform, its engineering vehicle, and its working method to solve the technical problems mentioned above, such as the incomplete installation of pins between the mounting platform and the rocker arm by manual labor and the cumbersome positioning steps.

[0005] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Summary of the Invention

[0006] This disclosure provides at least one platform, its engineering vehicle, and its working method.

[0007] In a first aspect, embodiments of this disclosure provide a mounting platform, including: a support arm having a support base at its tail end; A support platform having a rotating shaft, which is rotatably mounted on a support base; A hydraulic cylinder is mounted on a support base, with its movable end abutting against the bottom of the support platform; The support base also has at least one auxiliary positioning mechanism. The movable end of the auxiliary positioning mechanism is equipped with a limit block. The auxiliary positioning mechanism is adapted to drive the limit block to rotate circumferentially and slide axially. The end of the rotating shaft facing the auxiliary positioning mechanism has a groove; The auxiliary positioning mechanism has a position detector, and the detection end of the position detector faces the groove direction; The mounting platform also includes a control module, and the support arm, hydraulic cylinder, auxiliary positioning mechanism and position detector are all electrically connected to the control module; Furthermore, when the tail of the support arm is raised, the hydraulic cylinder extends outward to hold the bottom of the support platform in order to keep the support platform level; When the tail of the support arm stops, the hydraulic cylinder stops synchronously. The position detector detects the direction of the groove and feeds it back to the control module. The control module drives the auxiliary positioning mechanism to adjust the limit block to match the direction of the groove, and drives the limit block to insert into the groove to position the rotating shaft and the support platform.

[0008] In one optional embodiment, the auxiliary positioning mechanism includes an adjusting plate and a positioning cylinder, the adjusting plate being rotatably mounted on a support base, and the positioning cylinder being mounted on the side of the adjusting plate facing the rotating shaft. The limiting block is installed on the movable end of the positioning cylinder; The position detector is installed on the positioning cylinder and is located on one side of the limiting block.

[0009] In one optional embodiment, the support base also has a one-way locking motor, the movable end of which is coaxially connected to the adjustment disc. The output shaft of the one-way locking motor is equipped with a one-way locking bearing.

[0010] In one alternative embodiment, the support platform has a loading groove, and a snap-fit ​​plate is slidably disposed at the bottom of the loading groove; A guide rod is installed on one side of the snap-fit ​​plate, and a guide plate is also provided on the support platform. The guide rod passes through the guide plate and its axial direction is parallel to the movement direction of the snap-fit ​​plate.

[0011] In one optional embodiment, the snap-fit ​​plate has an adjustment plate on one side, and a limiting plate is also installed at the bottom of the support platform. A limiting groove is opened on the limiting plate, one end of the limiting plate is rotatably connected to the end of the snap-fit ​​plate, and the other end is inserted into the limiting groove. A control panel is also movably mounted on the support platform, and a control slot is provided on one side of the support platform. The control panel is movably mounted in the control slot, and one end of the control panel is rotatably connected to the middle of the limiting plate.

[0012] In one alternative embodiment, the support platform further includes a locking spring, with its two ends connected to the support platform and the control panel, respectively.

[0013] In one alternative embodiment, a notch is provided on one side of the snap-fit ​​plate, and a baffle is provided on the outer side of the support platform.

[0014] In one alternative embodiment, one end of the baffle is hinged to the support platform.

[0015] Secondly, this disclosure also provides an engineering vehicle, including the mounting platform as described above, wherein the engineering vehicle includes a frame and the mounting platform is mounted on the frame.

[0016] Thirdly, this disclosure also provides a method for operating a platform, wherein the method is executed using the platform described above, and the method includes: Step S1: The tail of the support arm is raised, and the hydraulic cylinder extends outward to hold the bottom of the support platform to keep the support platform level. In step S2, the support arm stops, the hydraulic cylinder stops synchronously, the position detector detects the direction of the groove and feeds it back to the control module; In step S3, the control module drives the auxiliary positioning mechanism to adjust the limiting block to match the direction of the groove, and drives the limiting block to insert into the groove to position the rotating shaft and the support platform.

[0017] The beneficial effects of this invention are that by setting an auxiliary positioning mechanism to position the rotating shaft, it assists the hydraulic cylinder in positioning the rotating shaft and the support platform, preventing the hydraulic cylinder from failing to provide sufficient support force when the equipment is held in a raised state for a long time. Simultaneously, since the center of gravity of the mounted engineering equipment is located behind the support platform, the direction of the torque on the support platform remains consistent. Therefore, by setting a one-way locking motor, it can lock after the limit block engages with the groove, balancing the torque.

[0018] Other features and advantages of the invention will be set forth in the description which follows, and will be apparent in part from the description, or may be learned by practicing the invention. The objects and other advantages of the invention are realized in the structures particularly pointed out in the description, claims, and drawings.

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] Research has revealed that in related technologies, engineering vehicles require specially designed mounting platforms to carry specialized equipment and perform tasks such as lifting and unloading. During operation, the mounting platform needs to be raised by lifting the rocker arm to elevate it, while simultaneously rotating in the opposite direction to maintain its horizontal position.

[0025] However, once the rocker arm is raised to its position, the hydraulic or pneumatic cylinders driving its rotation are insufficient to maintain the platform's level. Manual installation of a pin at the connection between the platform and the rocker arm is necessary for auxiliary positioning, posing a safety risk. Furthermore, the pin's positioning angle is limited and may not perfectly align with the rocker arm's raised angle. Therefore, after inserting the pin, the rocker arm height must be fine-tuned to secure it, making the operation cumbersome.

[0026] Therefore, there is an urgent need to design a mounting platform, its engineering vehicle, and its working method to solve the technical problems mentioned above, such as the incomplete installation of pins between the mounting platform and the rocker arm by manual labor and the cumbersome positioning steps.

[0027] The shortcomings of the above solutions are the result of the inventor's practical experience and careful research. Therefore, the discovery process of the above problems and the solutions proposed in this disclosure below should be considered as the inventor's contribution to this disclosure.

[0028] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, the embodiments and features described below can be combined with each other. Furthermore, in the accompanying drawings, the thickness of components may be exaggerated or reduced for the purpose of effectively describing the technical content.

[0029] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0030] Based on the above research, and referring to Figure 1 This disclosure provides a mounting platform, including a support arm 1, a support platform 3, a hydraulic cylinder 4, and a control module. The head of the support arm 1 is hinged to the engineering vehicle, and the tail end has a support seat 2. The bottom of the support platform 3 has a pivot 31, and the support platform 3 is rotatably mounted on the support seat 2 via the pivot 31. The support arm 1 and the hydraulic cylinder 4 are typically connected to the control module. The hydraulic cylinder 4 is mounted on the support seat 2, and its movable end abuts against the bottom of the support platform 3. When the support arm 1 is in a horizontal position, the support platform 3 also remains horizontal. When the head of the support arm 1 rotates to raise the tail end, the hydraulic cylinder 4 simultaneously extends outward and remains abutting against the bottom of the support platform 3, thereby keeping the support platform 3 horizontal.

[0031] Reference Figure 1 In at least one embodiment, the support base 2 also has at least one auxiliary positioning mechanism 5. Optionally, the rotating shafts 31 of the bearing platform 3 can be designed as two symmetrical ones, and the auxiliary positioning mechanisms 5 can also be designed as two corresponding to the rotating shafts 31.

[0032] Reference Figure 2 and Figure 3In at least one embodiment, a limiting block 51 is installed at the movable end of the auxiliary positioning mechanism 5. The auxiliary positioning mechanism 5 is adapted to drive the limiting block 51 to rotate circumferentially and slide axially. A groove 32 is formed at the end of the rotating shaft 31 facing the auxiliary positioning mechanism 5. Simultaneously, the auxiliary positioning mechanism 5 has a position detector 52, with its detection end facing the groove 32. The position detector 52 is also electrically connected to the control module. The position detector 52 can detect the direction of the groove 32 and feed the information back to the control module. The control module controls the auxiliary positioning mechanism 5 to rotate so that the direction of the limiting block 51 is aligned with the direction of the groove 32. Then, the auxiliary positioning mechanism 5 controls the limiting block 51 to move axially and insert it into the groove 32, thereby achieving the positioning of the rotating shaft 31. With the above configuration, when the tail of the support arm 1 is raised, the hydraulic cylinder 4 extends outward, holding against the bottom of the support platform 3 to keep the support platform 3 horizontal. On the other hand, when the tail of the support arm 1 stops, the hydraulic cylinder 4 stops synchronously, the position detector 52 detects the direction of the groove 32 and feeds it back to the control module. The control module drives the auxiliary positioning mechanism 5 to adjust the limit plug 51 to match the direction of the groove 32, and drives the limit plug 51 to be inserted into the groove 32 to position the rotating shaft 31 and the support platform 3.

[0033] Reference Figure 2 and Figure 3 In at least one embodiment, the auxiliary positioning mechanism 5 includes an adjusting plate and a positioning cylinder 54. The adjusting plate is rotatably mounted on the support base 2, and the positioning cylinder 54 is mounted on the side of the adjusting plate facing the rotating shaft 31. The limiting block 51 is mounted on the movable end of the positioning cylinder 54. The position detector 52 is mounted on the positioning cylinder 54 and located on one side of the limiting block 51. With the above arrangement, the rotation of the adjusting plate can drive the positioning cylinder 54 to rotate, thereby adjusting the circumferential position of the position detector 52. At the same time, since both the position detector 52 and the limiting block 51 are mounted on the positioning cylinder 54, the relative position of the position detector 52 and the limiting block 51 is fixed. The position sensor continuously detects the direction of the groove 32 and compares it with the direction of the limiting block 51, thereby ensuring that the limiting block 51 can be inserted into the groove 32.

[0034] Reference Figure 2In at least one embodiment, the support base 2 also has a one-way locking motor 21, the movable end of which is coaxially connected to the adjusting plate. The output shaft of the one-way locking motor 21 is equipped with a one-way locking bearing. Through the above arrangement, the one-way locking motor 21 achieves the effect of unidirectional rotation through the one-way locking bearing. At the same time, since the center of gravity of the engineering equipment is located behind the support platform 3, the direction of the torque on the support platform 3 is always consistent. Therefore, by setting the one-way locking motor 21, it can be locked after the limiting plug 51 is engaged with the groove 32, thus balancing the torque. After the limiting plug 51 is inserted into the groove 32, the torque is transmitted to the one-way locking bearing, ensuring that the limiting plug 51 positions and locks the rotating shaft 31.

[0035] Reference Figure 4 In at least one embodiment, the support platform 3 has a loading groove 33, and a snap-fit ​​plate 34 is slidably disposed at the bottom of the loading groove 33. A guide rod 35 is installed on one side of the snap-fit ​​plate 34, and the support platform 3 also has a guide plate 36. The guide rod 35 passes through the guide plate 36, and the axial direction of the guide rod 35 is parallel to the movement direction of the snap-fit ​​plate 34. Through the above arrangement, the guide plate 36 guides the direction of the guide rod 35, so that the guide rod 35 drives the snap-fit ​​plate 34. Figure 4 In the indicated directions, it can only slide left and right. The latching plate 34 slides to the left to open the loading slot 33, and slides to the right to close the loading slot 33. With the above arrangement, when loading the equipment, the latching plate 34 first opens to the left, and after the equipment is inserted into the loading slot 33, the latching plate 34 closes to the right, thereby locking the equipment.

[0036] Reference Figure 1 and Figure 4 In at least one embodiment, the snap-fit ​​plate 34 has an adjusting plate 37 on one side, and a limiting plate 38 is installed at the bottom of the support platform 3. A limiting groove 39 is formed on the limiting plate 38, one end of which is rotatably connected to the end of the snap-fit ​​plate 34, and the other end is inserted into the limiting groove 39. A control plate 310 is also movably mounted on the support platform 3, and a control groove 311 is formed on one side of the support platform 3. The control plate 310 is movably mounted within the control groove 311, and one end of the control plate 310 is rotatably connected to the middle of the limiting plate 38. With the above configuration, pushing or pulling the control plate 310 allows the adjusting plate 37 to control the position of the snap-fit ​​plate 34.

[0037] Reference Figure 1 and Figure 4 In at least one embodiment, the support platform 3 further includes a locking spring 312, with its two ends connected to the support platform 3 and the control panel 310, respectively. The locking spring 312 not only provides a reset for the control panel 310 but also pulls the latching plate 34 to clamp the device, thereby achieving the effect of locking the device within the loading slot 33.

[0038] Reference Figure 1 In at least one embodiment, a notch 313 is provided on one side of the snap-fit ​​plate 34, and a baffle 314 is provided on the outer side of the support platform 3. After the control panel 310 pulls the snap-fit ​​plate 34 toward the clamping device, the snap-fit ​​plate 34 can be snapped into position with the baffle 314 at the notch 313, thereby achieving the positioning of the control panel 310.

[0039] Reference Figure 1 and Figure 4 In at least one embodiment, one end of the baffle 314 is hinged to the support platform 3. The baffle 314 can be rotated to disengage from the notch 313, thereby releasing the control panel 310.

[0040] Furthermore, this disclosure also provides an engineering vehicle, including the mounting platform as described above. The engineering vehicle includes a frame 6, and a platform is mounted on the frame 6.

[0041] Furthermore, this disclosure also provides a method for operating a platform, wherein the method is executed using the platform described above, and the method includes: In step S1, the tail of the support arm 1 is raised and the hydraulic cylinder 4 extends outward to hold the bottom of the support platform 3 so as to keep the support platform 3 horizontal. In step S2, the support arm 1 stops, the hydraulic cylinder 4 stops synchronously, the position detector 52 detects the direction of the groove 32 and feeds it back to the control module; In step S3, the control module drives the auxiliary positioning mechanism 5 to adjust the limiting block 51 to match the direction of the groove 32, and drives the limiting block 51 to insert into the groove 32 to position the rotating shaft 31 and the support platform 3.
