Description

Technical Field

[0001] The present invention relates to the technical field of lifting equipment, and in particular to a hundred-ton-class safe heavy-load lifting platform. Background Art

[0002] In some large-scale experimental construction projects, a 100-ton lifting platform is needed. In the lifting equipment, due to the poor performance of traditional lifting platforms in leveling accuracy, it is difficult to ensure that the platform surface is completely consistent with the ground plane of each floor. This causes the load-carrying trolley to bump when entering and exiting the lifting platform car platform, affecting the stability and safety of cargo transportation. Therefore, a leveler will be set on the lifting platform to ensure the stability and safety of cargo transportation. Then the existing lifting platform has the following problems;

[0003] In the existing leveling device, there are generally two stopper assemblies, which may play a leveling role to a certain extent for ordinary lifting platforms, but for a 100-ton lifting platform, two stopper assemblies are far from meeting its use requirements. Hundred-ton lifting platforms require more stable and reliable leveling control due to their huge load-bearing weight. Two stopper assemblies cannot ensure that the platform surface is at the same height as the ground level of each floor, which may cause a large shake when the load-carrying trolley enters and exits the platform, and may even cause safety accidents;

[0004] At the same time, there is usually a lack of effective lubrication measures for the gear and rack parts of the driving mechanism of the lifting platform. Some lifting platforms do not have an automatic lubrication function and require manual regular addition of lubricating oil, which not only increases maintenance costs and workload, but may also cause increased wear between the gear and rack due to untimely lubrication, reducing the service life and operational reliability of the lifting platform. Some lifting platforms with lubrication functions are difficult to accurately control the amount of lubricating oil sprayed, and are prone to excessive spraying, which in turn leads to excessive power loss, affecting the operating efficiency and energy utilization of the lifting platform.

[0005] Therefore, it is necessary to design a new lifting platform to solve the above problems. Summary of the invention

[0006] The purpose of the present invention is to solve the shortcomings existing in the prior art, and a hundred-ton-class safe heavy-load lifting platform is proposed. The lifting platform is equipped with four stop assemblies and four stop pin shafts, so that when the one hundred-ton lifting platform is working, the platform surface is ensured to be consistent with the ground plane of each floor, so that the load-carrying trolley can enter and exit the lifting platform more smoothly and without bumps.

In the initial state, the liquid inlet ends of the two bent pipes 30 are higher than the liquid level of the lubricating oil, and two adding ports are provided on the front side of the liquid storage box 39 for adding lubricating oil, and the adding ports are provided with sealing plugs.

[0035] Among them, the pressure rods 23 are fixed on the rear sides of the two rectangular frames 20, and the counting sensors 24 are fixedly connected to the inner walls of the rear sides of the two movable boxes 19. An adjusting component is provided in the liquid storage box 39, and the adjusting component includes an electromagnet 32 ​​fixedly connected in the liquid storage box 39. Two pistons 31 are sealed and slidably connected in the liquid storage box 39. The two pistons 31 are elastically connected to the adjacent sides of the electromagnet 32 ​​through a second spring 34. A controller is provided. When the counting number of times the counting sensor 24 counts reaches a preset number, an electrical signal is generated and transmitted to the controller. The controller controls the electromagnet 32 ​​to be energized. The two pistons 31 are both made of magnetic materials, so that the two pistons 31 move away from each other.

[0036] Among them, the inner top of the liquid storage box 39 is provided with an opening, and a partition net 36 is provided in the opening. Circular openings are provided on the two pistons 31. The inner bottom of the liquid storage box 39 is fixedly connected with two hollow plates 33. The upper ends of the two hollow plates 33 are provided with multiple air outlets. The two hollow plates 33 are located directly below the partition net 36. The bottoms of the two hollow plates 33 are connected with the rear space of the corresponding mobile box 19 through the air outlet pipe 26. The rear space of the mobile box 19 is connected with the outside world through the air inlet pipe 25. Both the air outlet pipe 26 and the air inlet pipe 25 are provided with one-way valves. The outside gas enters the rear space of the mobile box 19 in one direction through the air inlet pipe 25, and the gas in the rear space of the mobile box 19 enters the two hollow plates 33 in one direction through the air outlet pipe 26.

[0037] The functional principle of the present invention can be explained through the following operation mode: when the lifting platform 10 receives an instruction to reach the stop floor, the stop pin shaft 13 of the leveling assembly is in a retracted state, and when the lifting platform 10 reaches 200 mm above the stop floor baffle 37 (the distance between the lower edge of the stop pin shaft 13 and the upper surface of the baffle 37), the floor limiter is triggered, and an instruction is issued to the second double-axis motor 35, so that the second double-axis motor 35 runs to drive the two rotating rods 17 to rotate counterclockwise;

[0038] The two rotating rods 17 rotate to drive the two rotating gears 18 to rotate. Since the multiple racks 16 are in meshing state with the rotating gears 18, the corresponding two racks 16 move in opposite directions, and then the corresponding stop pin shafts 13 move in opposite directions, extending the stop pin shafts 13. The stop pin shafts 13 are extended and trigger the limit switch, and the stop pin shafts 13 of the lifting platform fall to the 100t leveling device stop hinge baffle plate;

[0039] When loading and unloading of goods is completed, the lifting platform receives new instructions and needs to go to other floors. At this time, the lifting platform 10 is lifted by 200mm, triggering the floor limit switch. The limit switch works and sends instructions to the second double-axis motor 35, so that the second double-axis motor 35 drives the two rotating rods 17 to rotate clockwise. At this time, the stop pin shaft 13 retracts and the stop pin shaft 13 retracts, triggering the limit switch, and the lifting platform can perform the next lifting action.

[0040] When the second dual-axis motor 35 drives the two rotating rods 17 to rotate counterclockwise, the two incomplete gears 21 will rotate. Since the two incomplete gears 21 are in meshing with the plurality of tooth edges 22 in the initial state, the two rectangular frames 20 move forward. When the incomplete gears 21 are not meshing with the tooth edges 22, the rectangular frames 20 will be reset under the elastic action of the first spring 28. When the rotating rod 17 rotates clockwise, the two rectangular frames 20 will move backward. When the incomplete gears 21 are not meshing with the rack 16, the rectangular frames 20 will move back.

[0041] Since in the initial state, the two pistons 31 are close to the electromagnet 32, and the two second springs 34 are in a compressed state, the liquid level of the lubricating oil in the liquid storage box 39 is lower than the liquid inlet end of the bent pipe 30. At this time, the rectangular frame 20 moves forward, the space in front of the mobile box 19 is reduced, and the air pressure increases, so that the gas is sprayed through the lubrication pipe 40 at the meshing position of the rotating gear 18 and the rack 16. When the rectangular frame 20 moves backward, the space in front of the rectangular frame 20 is increased, and the air pressure is reduced. At this time, the external gas enters the liquid storage box 39 through the opening and the round mouth, and then enters the space in front of the mobile box 19 through the bent pipe 30;

[0042] Each time the rectangular frame 20 moves forward and backward, the pressure rod 23 will squeeze the counting sensor 24 once, so that the counting sensor 24 counts once. When the counting sensor 24 counts to a preset number of times (the triggering number of the counting sensor 24 can be set in advance to twenty times), the counting sensor 24 will generate an electrical signal to transmit to the controller, and the controller and the control electromagnet 32 ​​will be energized. After the electromagnet 32 ​​is energized, a repulsive force is generated on the two pistons 31, so that the two pistons 31 move in opposite directions. At this time, the space on the left and right sides of the liquid storage box 39 is reduced, and the liquid level of the lubricating oil will be located above the bent pipe 30. At this time, the forward and backward movement of the rectangular frame 20 will suck the lubricating oil into the moving box 19, and then spray it on the meshing position of the rotating gear 18 and the rack 16 through the lubrication pipe 40 to lubricate the rotating gear 18 and the rack 16;

[0043] When the rectangular frame 20 moves forward, the outside air enters the rear space of the moving box 19 in one direction through the air inlet pipe 25. When the rectangular frame 20 moves backward, the gas in the rear space of the moving box 19 will be pressed into the air outlet pipe 26, and then sprayed vertically upward through the hollow plate 33, blowing away the dust and other impurities adsorbed on the partition net 36.

[0044] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
