Description

Technical Field

[0001] This invention relates to the field of maintenance and transfer platform technology, specifically a self-leveling and lifting maintenance and transfer platform. Background Technology

[0002] Currently, among the problems encountered with motors mounted on elevated platforms during operation, the motor, being 4 meters high with no accessible forklift path, and possessing significant mass, often wobbles during transport due to uneven terrain with numerous steps. This imbalance in the center of gravity poses a risk of tipping over. Existing motor transfer vehicles mostly use liftable models, which only consider the lifting function and not how to move the motor onto the platform when the trolley reaches the same height. Furthermore, most transfer trolleys rely on manual dragging for horizontal movement, which is time-consuming and labor-intensive.

[0003] Existing liftable maintenance and transfer platforms have the following problems:

[0004] 1. In the use of existing liftable maintenance and transfer platforms, the transfer platforms lack hoisting mechanisms, and the transfer motors are mostly moved horizontally by manual dragging, which is not convenient for flexible movement and is laborious.

[0030] The present invention provides the following embodiments.

[0031] Example 1

[0032] This invention provides a self-leveling, liftable maintenance and transfer platform, such as... Figure 1 As shown, it includes a base frame 1, with a moving mechanism 2 installed at each of the four corners of the lower end of the base frame 1. The upper end of the base frame 1 is connected to a top frame 4 via a lifting mechanism 3. The upper end of the top frame 4 is connected to a platform 5, and a hoisting mechanism 6 is connected to the platform 5.

[0033] Preferably, the moving mechanism 2 includes: a hydraulic rod 7, the telescopic end of the hydraulic rod 7 is fixedly connected to the bottom of the base frame 1, and a fixed plate 8 is fixedly connected to the bottom of the hydraulic rod 7. A rotating shaft 9 is rotatably connected to the fixed plate 8. A wheel frame 10 is fixedly connected to the rotating shaft 9. Each wheel frame 10 is connected to at least three lifting wheels 11 arranged at intervals along its circumference. The lifting wheels 11 are rotatably connected to the corresponding wheel frame 10. The two ends of the horizontal rod 12 are hinged to the hydraulic rods 7 on the left and right sides of the base frame 1.

[0034] Preferably, the moving mechanism 2 is driven by a drive device, and the drive device is equipped with a stepper motor 13.

[0035] Preferably, the lifting mechanism 3 includes: two scissor lift frames 14 arranged front to back, the left end of the bottom of the scissor lift frame 14 is hinged to the top of the base frame 1, the first slider 15 is hinged to the right end of the bottom of the scissor lift frame 14 and is slidably connected in the groove 16 embedded in the base frame 1, the scissor lift frame 14 is driven to lift by an electric hydraulic rod 17, the left side of the bottom of the top frame 4 is hinged to the left end of the top of the scissor lift frame 14, the second slider 18 is slidably connected in the groove 19 embedded in the top frame 4 and is hinged to the right end of the top of the scissor lift frame 14.

[0036] Both the moving mechanism 2 and the hoisting mechanism 6 of the present invention can adopt existing technologies.

[0037] The working principle and beneficial effects of the above technical solution are as follows:

[0038] The aforementioned base frame 1 has four moving mechanisms 2 installed at its bottom corners. These moving mechanisms, driven by a drive unit, enable the horizontal movement of the maintenance and transfer platform. The stepper motor 13 in the drive unit allows the maintenance and transfer platform to climb over steps. The stepper motor 13 drives the rotating shaft 9 to rotate, which in turn drives the fixedly connected wheel frame 10 to rotate synchronously. The lifting wheels 11, spaced circumferentially along the wheel frame 10, rotate when encountering steps, allowing the maintenance and transfer platform to climb them. Simultaneously, pressing the button for the front wheels to climb over steps activates the mechanism. Hydraulic rod 7 is depressurized, the trolley moves forward, and lifting wheel 11 rotates to overturn the step. After the front wheel has completely overturned, the rear wheel overturning button is pressed, the front wheel is hydraulically pressurized, hydraulic rod 7 returns to its previous hydraulic length, and the trolley moves forward. The rear wheel hydraulic rod 7 is depressurized, and after overturning the step, the rear wheel is pressurized to return to the normal height. The hydraulic rods 7 on the left and right sides of the base frame 1, which are hinged by horizontal rod 12, are always at the same horizontal height. This realizes the self-leveling function of the maintenance and transfer platform when overturning the step, ensuring that the transfer motor on the platform 5 is always in a horizontal state.

[0039] By setting up a lifting mechanism 3, when it is necessary to move the transfer motor on the maintenance transfer platform to a certain height, several electro-hydraulic rods 17 connected to the front and rear sides of the scissor lift frame 14 realize the height adjustment of the top frame 4, thereby enabling the lifting and adjustment of the platform 5 fixedly connected to the top of the top frame 4, thus completing the transfer of the transfer motor to the designated height. The hydraulic rods can also be pneumatic lifting rods.

[0040] The self-leveling liftable maintenance and transfer platform of the present invention achieves a self-leveling function when crossing steps during the transfer of the motor, avoiding the risk of tipping over. It can also adjust the height of the transfer motor according to the specified height of the maintenance and transfer platform. The present invention solves the following problems of the prior art mentioned in the background: the existing liftable maintenance and transfer platform cannot achieve a self-leveling function when crossing steps during the transfer of the motor, which easily causes the risk of tipping over.

[0041] Example 2

[0042] Based on Example 1, such as Figures 1-4 As shown, the platform 5 is fixedly connected to the top of the top frame 4, and both the platform 5 and the top frame 4 have hollow structures in the middle. The left and right sides of the platform 5 are respectively provided with cavities 20. Several pulleys 21 are rotatably connected to several rolling shafts 22 in a corresponding manner. The rolling shafts 22 are fixedly connected to the two side walls of the cavity 20. The two sides of the slide plate 23 penetrate the side walls of the cavity 20 and are embedded in the platform 5. The bottom of the slide plate 23 is slidably connected to several pulleys 21, and the slide plate 23 is slidably connected to the inner wall of the cavity 20. Two mounting slots 24 are fixedly connected to the front side of the platform 5 at a distance, and two buckles 25 are connected to the mounting slots 24.

[0043] Preferably, the hoisting mechanism 6 includes: two slide rails 26, which are fixedly connected to the left and right sides of the top of the platform 5 respectively; the bottom of the support frame 27 is slidably connected to the two slide rails 26; the support frame 27 adopts an I-beam structure; the drive assembly 28 is connected to the top of the support frame 27; the lifting assembly 29 is connected to the drive assembly 28; the hook device 30 is connected to the lifting assembly 29; and the controller 31 is fixedly connected to the top of the support frame 27. The controller 31 is electrically connected to the drive assembly 28, the lifting assembly 29, and the hand chain hoist 32.

[0044] Preferably, the two sets of guardrails 33 are fixedly connected to the left and right sides of the top of the platform 5, the left sides of the two baffles 34 are respectively hinged to the front and rear ends of the left guardrail 33, and the two limiting buckles 35 are respectively fixedly connected to the front and rear ends of the right guardrail 33, and the right sides of the two baffles 34 are connected to the two limiting buckles 35 one by one.

[0045] Preferably, it also includes a control console, which is fixedly connected to the top side of the base frame 1 and electrically connected to the moving mechanism 2 and the lifting mechanism 3.

[0046] The beneficial effects of the above technical solution are as follows:

[0047] The aforementioned hollow structure, achieved through the platform 5 and top frame 4, works in conjunction with the hoisting mechanism 6 to hoist and horizontally move the transfer motor on the maintenance transfer platform. When the transfer motor is hoisted onto the platform 5, the retaining clip is first removed from the mounting slot 24. Then, the pull ring of the sliding plate 23, which is slidably connected to the cavity 20 of the platform 5, is pulled. This removes the sliding plate 23 from the platform 5, resulting in a hollow structure in the center of the platform 5. This allows the transfer motor to be vertically lifted and lowered on the maintenance transfer platform. At this time, the drive assembly 28 and lifting assembly 29 in the hoisting mechanism 6... The hook device 30 is used to lift the transfer motor. When the transfer motor is lifted to the same height as the platform 5, the slide plate 23 is pushed into the cavity 20 of the platform 5 to facilitate the next step of placing the transfer motor on the platform 5. At this time, the hand chain hoist 32 in the hoisting mechanism 6 is controlled to move the hoisting mechanism 6 along the slide rail 26 to the designated position. The drive component 28 and the lifting component 29 are controlled to drive the hook device 30 to place the transfer motor on the platform 5 and release the force on the hook device 30. This completes the hoisting of the transfer motor onto the platform 5.

[0048] The guardrails 33 set on both sides of the platform 5, together with the baffles 34 connected to both sides of the guardrails 33, can prevent the transfer motor on the platform 5 from sliding and falling off during the transfer process, thereby causing safety hazards during the movement of the maintenance transfer platform. Secondly, one side of the baffle 34 can rotate around the guardrail 33, which makes it convenient for the transfer motor on the platform 5 to be moved off the platform 5. The two limit buckles 35 can fix the baffle 34.

[0049] This invention adds a hoisting mechanism 6, pulleys 21, and a sliding plate 23 to the loading platform, enabling the transfer motor on the loading platform 5 to move horizontally without manual dragging. This reduces the workload for workers and improves transfer efficiency. This invention solves the following problems of the prior art mentioned in the background: Existing liftable maintenance transfer platforms lack a hoisting mechanism 6, and the transfer motors are mostly moved horizontally by manual dragging, which is inconvenient, laborious, and requires considerable effort.

[0050] Example 3

[0051] Based on Example 1 or 2, such as Figure 5As shown, it also includes a stabilizing mechanism 36, which includes: two electric telescopic rods 37, the fixed ends of several electric telescopic rods 37 are fixedly connected to the upper end of the platform 5 at intervals, a fixing frame 38 is fixedly connected to the telescopic ends of the two electric telescopic rods 37, a groove 39 is provided on the rear side of the fixing frame 38, and grooves 40 are symmetrically provided on the left and right sides of the fixing frame 38. The grooves 40 communicate with the grooves 39, two irregular grooves 41 are embedded on the left and right sides of the grooves 39, and two sets of fixing components are connected to the left and right sides of the fixing frame 38.

[0052] Preferably, the fixing assembly on the left includes a transmission rod 42, which is slidably connected in the irregular groove 41; a transmission rod 43 is hinged to the transmission rod 42; a transmission rod 44 is hinged to the transmission rod 43 in the groove 40; a toggle rod 45 is hinged at its middle to the side wall of the fixing frame 38, and one end of the toggle rod 45 is hinged to the middle of the transmission rod 44; a transmission rod 46 is hinged to the transmission rod 44, and the transmission rod 46 is hinged to the side wall of the fixing frame 38; one side of the clamping block 47 is rotatably connected in the groove 40; and a transmission rod 48 is hinged to the top of the clamping block 47. A sliding groove 49 is provided on the transmission rod 48, and the hinge point between the transmission rod 46 and the transmission rod 44 is slidably connected in the sliding groove 49; a rubber pad 50 is fixedly connected to the side wall of the clamping block 47; and both ends of the transmission rod 51 are hinged to the two transmission rods 42.

[0053] The beneficial effects of the above technical solution are as follows:

[0054] By setting up a stabilizing mechanism 36, when the transfer platform needs to transfer the transfer motor, the actuating rod 45 in the stabilizing mechanism 36 is activated. The actuating rod 45 drives the transmission rod three 44 to move upward, and the transmission rod three 44 drives the transmission rod two 43 to move upward simultaneously. This causes the transmission rod one 42, which is hinged to the transmission rod two 43, to slide to both sides along the irregular groove 41. At the same time, as the transmission rod three 44 moves upward, it drives the hinged transmission rod four 46 to rotate upward along the sliding groove three 49 on the transmission rod five 48, thereby stabilizing the transmission... The clamping block 47 of the hinged rod 48 rotates counterclockwise in the groove 2 40. When the two transmission rods 42, which are hinged by the transmission rod 6 51, slide to the left side of the irregular groove 41 near the fixed frame 38, the transmission rods 42 and the irregular groove 41 are locked. Next, the transfer motor is placed in the stabilizing mechanism 36 on the platform 5 by the hoisting mechanism 6. The actuating rod 45 is then moved to make the transmission rod 3 44 move downward, so that the transmission rod 2 43 drives the transmission rod 42 to slide to the right along the irregular groove 41. At the same time, the transmission rod 47 rotates counterclockwise in the groove 2 40. 8 drives the clamping block 47 to rotate clockwise along the groove 40. As the transmission rod 44 and transmission rod 46 slide to the left along the slide groove 49, the two transmission rods 42 hinged to the transmission rod 51 slide in the irregular groove 41 and lock when they are close to the right side of the irregular groove 41. The two sets of fixing components are linked by the transmission rod 51, so that the two clamping blocks 47 can effectively fix the maintenance transfer platform when transferring the motor, preventing the transfer motor from moving on the platform 5 and causing the maintenance transfer platform to tip over during the movement. The rubber pad 50 fixedly connected to the clamping block 47 can avoid damage to the surface of the equipment when clamping the transfer motor. The above makes the maintenance transfer platform safer and more reliable when transferring the transfer motor in conjunction with the moving mechanism 2, avoiding the tipping caused by the transfer motor moving on the maintenance transfer platform, effectively avoiding the risks brought about by the transfer, reducing the difficulty of operation for the staff, improving the efficiency of the maintenance transfer platform in transferring the transfer motor, and making it safer and more reliable to use.

[0055] Obviously, those skilled in the art can make various modifications and variations to this invention without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this invention and their equivalents, this invention also intends to include these modifications and variations.
