Description

Technical Field

[0001] The utility model belongs to the technical field of tower equipment manufacturing and relates to a tray transfer device. Background Art

[0002] A tower device refers to equipment used for physical processes such as separation or absorption, which changes the composition of a complex gas or liquid mixture, also known as "tower equipment", and has a relatively large ratio of height to diameter. A tray is the main component in a plate tower that provides a place for gas-liquid mass transfer and heat transfer. It enables two fluids to closely exchange heat and mass between two phases to achieve the purpose of separating the components of a liquid mixture or a gas mixture. It mainly consists of gas-liquid contact elements (such as floating valves, bubble caps, sieve holes, etc.), liquid receiving trays, overflow weirs, downcomers (or downcomer plates), tray supports, and fasteners, etc. When the tower diameter is small, each layer of the tray is a single piece, called a monolithic tray. After the tray is manufactured, it is usually transported piece by piece to the entrance of the tower device and then installed inside the tower device. The trays are heavy, and there are a large number of trays installed inside the tower device. Transporting the trays piece by piece is time-consuming and laborious, with low efficiency.

Detailed Embodiments

[0015] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0016] Embodiment 1, please refer toFigure 1-2 , the present utility model provides a tray transfer device, which is used when installing trays 6 for a tower vessel 9. It includes a movable trolley 1, on which a lifting mechanism is provided. The upper end of the lifting mechanism is fixedly connected with a column 2 for the column 2 to be lifted and lowered; the upper end of the column 2 is fixedly connected with a cross beam 3; a plurality of sliding sleeves 4 are slidably sleeved on the cross beam 3; a hook 5 is provided at the lower end of each sliding sleeve 4 for hanging the tray 6; a foot-operated oil pump 7 is fixedly provided on the trolley 1, the foot-operated oil pump 7 is connected with an oil cylinder 8 fixedly provided on the trolley 1, and the telescopic rod of the oil cylinder 8 is connected with the lifting mechanism for providing lifting power for the lifting mechanism.

[0017] It can be seen that by hanging a plurality of trays 6 with a plurality of sliding sleeves 4, the plurality of trays 6 are collected on the trolley 1 and can be transferred together with the trolley 1, saving labor for handling. The lifting mechanism can drive the tray 6 to be lifted and lowered, facilitating alignment with the inlet of the tower vessel 9; the foot-operated oil pump 7 and the oil cylinder 8 drive the lifting mechanism, enabling the trolley 1 to have its own power source and eliminating the need for an external power source to lift the tray 6, which is convenient to use. Thus, this embodiment can collect a plurality of trays 6 on the movable trolley 1, transfer a plurality of trays 6 at one time, and a lifting device is provided on the trolley 1 to facilitate lifting the tray 6 to the inlet of the tower vessel 9, which is labor-saving and convenient, improves efficiency, and facilitates the installation of the tray 6.

[0018] An exemplary embodiment of the lifting mechanism, the lifting mechanism is a scissor lifting mechanism; the column 2 is fixedly connected to the upper surface of a support plate 13 at the upper end of the scissor lifting mechanism; one end of the oil cylinder 8 is fixedly connected with the foot-operated oil pump 7, and its telescopic rod is connected with a connecting rod 14 of the scissor lifting mechanism for driving the support plate 13 to be lifted and lowered when the oil cylinder 8 expands and contracts. Among them, the scissor lifting mechanism takes the body of the trolley 1 as the base, the support plate 13 as the lifting member, and a pair of hinged connecting rods 14 located between the base and the support plate 13 as the lifting linkage mechanism. By driving one connecting rod 14 to change the angle and posture with the oil cylinder 8, the support plate 13 can be driven to be lifted and lowered. Since the scissor lifting mechanism is a prior art, its internal structure and principle will not be elaborated.

[0019] In a preferred embodiment, a universal wheel 12 is connected to the lower end of the body of the trolley 1, and a handrail 11 is fixedly connected to one side thereof for pushing the trolley 1 to move. The universal wheel 12 makes the trolley 1 move flexibly. By borrowing the handrail 11 to push the trolley 1, no power equipment is required, saving costs.

[0020] In order to further reduce the resistance when the sliding sleeve 4 slides, the body of the sliding sleeve 4 is a U-shaped plate, including the top of the top plate and the wing plates 41 fixed to both sides of the top plate; a groove 31 is provided at the upper end of the cross beam 3; the lower end of the roller 42 is clamped in the groove 31, and the wheel axles 43 fixed to both ends thereof are inserted into the preset shaft holes of the two wing plates 41, so that the sliding sleeve 4 can be slidably sleeved on the cross beam 3; below the cross beam 3, both ends of the connecting rod 44 are respectively fixed to the lower parts of the two wing plates 41, and the hook 5 is fixed to the connecting rod 44. It can be seen that through the cooperation of the roller 42 and the groove 31, the sliding friction between the sliding sleeve 4 and the cross beam 3 is changed to the rolling friction of the roller 42, with less resistance, and the sliding of the sliding sleeve 4 is smoother, making it easier for the tray 6 to enter the inlet of the tower 9, and it is more convenient and labor-saving to use.

[0021] In summary, this embodiment can collect multiple trays 6 onto the movable trolley 1, and multiple trays 6 can be transported at one time. And a lifting device is provided on the trolley 1, which is convenient for lifting the tray 6 to the inlet of the tower 9, saving labor and being convenient, improving the efficiency and facilitating the installation of the tray 6.

[0022] Embodiment 2, please refer to Figure 3 。

[0023] The difference between this embodiment and Embodiment 1 is that the implementation manner of the lifting mechanism is different, but it also has the same effect as Embodiment 1. The lifting mechanism includes a vertical pipe 15 fixed to the upper surface of the trolley 1 and a connecting seat 21 fixed to one side of the column 2; the lower end of the column 2 is inserted into the vertical pipe 15; the lower end of the oil cylinder 8 is fixed to the trolley 1, and the upper end of its telescopic rod is connected to the connecting seat 21, which is used to drive the column 2 to lift and lower. More preferably, the vertical pipe 15 is a square pipe and the column 2 is a square column, which restricts the disorderly rotation of the column 2 and makes the lifting and lowering of the column 2 more stable. Among them, a corner support is provided at the joint of the lower end of the vertical pipe 15 and the vehicle body to improve the stability of the vertical pipe 15.
