Description

Technical Field

[0001] The present invention relates to a stage, and particularly to a lifting and horizontal conveying stage. Background Art

[0002] Among numerous express sorting points, handling express deliveries is the most basic daily work item. For numerous express sorting points, trucks will constantly deliver truckloads of goods, and then manual handling is carried out. Especially when certain shopping festivals arrive, the number of express deliveries will be extremely large. Currently, express deliveries are usually handled manually, but when there are too many goods, the efficiency of manual handling obviously cannot meet the requirements.

[0003] Using special equipment to reduce the work intensity and improve labor efficiency is a common means, such as using a conveyor belt. However, conventional conveyor belts are generally fixed and large in size, making them inconvenient to use. In addition, the height of the conveyor belt is also fixed and cannot control the conveying height. During the process of express handling, sometimes short-distance conveying is required, and the position is constantly changing, that is, the starting point and the ending point of the conveying are always changing; at the same time, due to the uncertain parking position and carriage height of the truck, a lightweight, movable and height-adjustable conveying device is needed;

[0004] Similarly, during other production and construction processes, for heights and positions that cannot be reached when workers stand naturally, ladders are often needed. Ladders not only have poor stability and pose safety hazards, but also cannot provide a larger working space for workers and there are also safety hazards. For occasions where the position of the construction site changes in the horizontal or vertical direction, when using a ladder, only the process of climbing up and down repeatedly and carrying the ladder can be adopted, which is time-consuming and laborious and has low efficiency.

[0005] Existing lifting devices often adopt hydraulic lifting methods, such as hydraulic scissor brace lifting platforms. However, it is difficult to synchronously control multiple hydraulic cylinders, with high costs and a risk of oil leakage. The safety factor of using a pulley lift is relatively low, and it only has a single lifting function and cannot meet the requirements of transporting at different heights and different horizontal positions.

[0037]

Embodiment

[0038] As Figures 1 - 5 shown, a lifting and horizontal conveying table in this embodiment includes a base 3, a bearing table 26, a conveying plate 24, a lifting mechanism and a conveying plate translation mechanism; the specific structure is as follows:

[0039] Sliding rails 31 are arranged on the base 3 and are slidably connected to the first sliding seat 11 and the second sliding seat 10, so that the first sliding seat 11 and the second sliding seat 10 can slide horizontally on the base 3. A first bearing seat 21 and a second bearing seat 16 are arranged side by side at the same end of the base 3 for connecting the crank one 20 and the crank two 17 with the corresponding first lead screw 22 and second lead screw 25.

[0040] The bearing table 26 is a rectangular plate, and two long grooves, namely sliding grooves 27, are longitudinally cut on it. A slideway is arranged at the bottom of the conveying plate 24 to cooperate with the sliding grooves 27 so that the conveying plate 24 can slide horizontally on the bearing table 26.

[0041] As Figure 6 shown, the telescopic rod 19 is of a sleeve type structure. A plurality of positioning holes are arranged along the height direction on one side of the outer cylinder, and an elastic locking pin 33 is arranged on the corresponding side of the inner cylinder to cooperate with the positioning holes for locking after the bearing table 26 is adjusted in place.

[0042] The crank one 20 is connected to the first sliding seat 11 through the first lead screw 22, and the first sliding seat 11 is matched with the first gear through the fixedly connected first rack. In this embodiment, racks A 12 and racks B 4 are respectively arranged at both ends of the first sliding seat 11 and are meshed and driven with the corresponding gears A 14 and gears B 7. Two groups of transmission mechanisms are symmetrically arranged on both sides of the bearing table 26, and the active swing rod B 6, the driven swing rod B 5, the active swing rod C 28, the driven swing rod C 29, and the connecting rod 1 together form two groups of four-bar linkages between the base 3 and the bearing table 26, so that the movement of the bearing table 26 during lifting is more stable and reliable.

[0043] The crank two 17 is connected to the second sliding seat 10 through the second lead screw 25, the second sliding seat 10 is matched with the second gear through the fixedly connected second rack, and the swing rod 9 is connected to the conveying plate 24 through a rocker-slider mechanism (transmission mechanism two). Two groups of transmission mechanisms two are symmetrically arranged on both sides of the bearing table 26, making the horizontal movement of the conveying plate 24 more stable.

[0044] The working principle of the lifting and horizontal conveying platform in this embodiment is as follows: When turning the first crank 20, the first lead screw 22 rotates accordingly. The first lead screw 22 is in threaded engagement with the first sliding seat 11, so that the first sliding seat 11 can slide along the slide rail 31 on the base 3. Rack A 12 and rack B 4 are respectively arranged at both ends of the first sliding seat 11. When the first sliding seat 11 slides, the two racks 12 and 4 drive the corresponding two gears 14 and 7 to rotate synchronously, causing the three active swing rods 13, 6, 29 and the three driven swing rods 23, 5, 28 to rotate. An expansion link 19 is provided between the base 3 and the bearing platform 26. When the active swing rod and the driven swing rod rotate, the expansion link 19 expands and contracts up and down, enabling the bearing platform 26 to perform a lifting motion. The function of the expansion link 19 is, on the one hand, to ensure that the bearing platform 26 can only move up and down, and on the other hand, to ensure that the bearing platform 26 is locked and fixed after being adjusted to the required height to keep the entire structure stable. After the lifting action is completed, turn the second crank 17. The second sliding seat 10 slides through the second lead screw 25, and the second rack 2 drives the second gear 8 to rotate, thereby causing the rocker-slider mechanism to act. Since the conveying platform 24 is connected to the bearing platform 26 through the chute 27 and the slideway, when the rocker-slider mechanism works, the conveying plate 24 can be driven to move horizontally longitudinally along the bearing platform 26. The specific process is as follows:

[0045] Shake the first crank 20 in the lifting mechanism to make it rotate. The first crank 20 is connected to the base 3 through the first bearing block 21. The end of the first crank 20 is connected to the first lead screw 22. The first lead screw 22 is in spiral engagement with the first sliding seat 11. When shaking the first crank 20, the torque is transmitted to the first sliding seat 11 through the spiral engagement, causing the first sliding seat 11 to slide forward along the slide rail 31. Rack B 4 and rack A 12 are respectively arranged at both ends of the first sliding seat 11. Among them, rack B 4 meshes with gear B 7, and rack A 12 meshes with gear A 14. When the first sliding seat 11 slides, rack B 4 drives gear B 7 to rotate, and rack A 12 drives gear A 14 to rotate. The transmission ratios of the two are the same, so that the rotational speeds of gear B 7 and gear A 14 are the same. When gear B 7 and gear A 14 rotate, the active swing rod B 6 and the active swing rod A 13 will also rotate accordingly, and their rotation angles and rotational speeds are the same. The active swing rod B 6 and the active swing rod A 13 drive the bearing platform 26 to move synchronously through the corresponding driven swing rod B5 and driven swing rod A 23. The outer cylinder of the expansion link 19 is fixedly connected to the base 3, and the inner cylinder is fixedly connected to the bearing platform 26. Due to the limitation of the expansion link 19, the bearing platform 26 can only move up and down in the vertical direction. When the rotation direction of the first crank 20 is opposite, the lifting direction of the bearing platform 26 is also opposite.

[0046] When the bearing platform 26 reaches an appropriate height and needs to be maintained at this height, the elastic locking pin 33 on the expansion link 19 is stuck in the positioning hole at the corresponding height to make it no longer expand and contract, that is, it is automatically locked and plays a role in supporting the bearing platform 26.

[0047] When the vertical position of the carrier table 26 has been fixed, turn the second crank 17. The second crank 17 is connected to the base 3 through the second bearing block 16. The end of the second crank 17 is connected to the second lead screw 25. The second lead screw 25 is in screw fit with the second slide block 10. When the second crank 17 is turned, the torque is transmitted to the second slide block 10 through the screw fit, causing the second slide block 10 to slide. A second rack 2 is provided on the second slide block 10 and meshes with a second gear 8. When the second slide block 10 slides, the second gear 8 is driven to rotate by the second rack 2. The rocker 9 rotates accordingly. The rocker 9 is connected to the slide rod 18 through a slider 15. When the rocker 9 rotates, the slide rod 18 drives the conveying plate 24 to move accordingly. The conveying plate 24 and the carrier table 26 slide through the cooperation of a chute 27 and a slideway. Therefore, the conveying plate 24 can only move horizontally longitudinally along the carrier table 26.

[0048] The present invention has the characteristics of reasonable design, simple structure, convenient operation and high working efficiency. It requires a relatively small working space and can be applied to various occasions where a workbench with lifting and translation functions is needed.

[0049] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
