Description

Technical Field

[0001] The utility model relates to a plate lifter, in particular to a plate lifter used for transporting plate-shaped materials such as tiles. Background Art

[0002] Ceramic tiles are a type of acid- and alkali-resistant porcelain or stone material made from refractory metal oxides and semi-metal oxides through a process of grinding, mixing, pressing, glazing, and sintering. They are often heavy and have sharp edges, making them difficult to transport. Therefore, they are often transported using a lift.

[0003] For example, the patent application number 202222991335.7 discloses a plate lifter that is easy to adjust. By setting a first lifting rod, a second lifting rod, a connecting block, a small suction cup, a tile and a fixing device, after adjusting the length of the first lifting rod and the second lifting rod, the use of the fixing device can fix the first lifting rod and the second lifting rod, and then use a plurality of small suction cups to absorb the tiles, so that the first lifting rod and the second lifting rod can lift the tiles. It has the advantages of a device for protecting large tiles and easy length adjustment. It uses multiple groups of large suction cups to absorb the tiles, so the application has fewer points of action on the tiles. If the force of a group of suction cups on the tiles changes or fails, the tiles cannot be stably transported. Utility Model Content

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments, but they are not intended to limit the present invention.

[0021] Example 1. A plate lifter, comprising: Figure 1-5As shown, it includes a profile lifting rod 1, and an air pump assembly is provided at the end of the profile lifting rod 1. The bottom inner side of the profile lifting rod 1 is provided with a gas flow channel 2 from one end of the profile lifting rod 1 to the other end and can cooperate with the air pump assembly to extract air. The lower side of the profile lifting rod 1 is provided with multiple groups of small suction cups 4 connected to the gas flow channel 2. The number of small suction cups 4 is greater than two, and both ends of the profile lifting rod 1 are provided with sealing members 3 for sealing the end face of the profile lifting rod 1.

[0022] The number of the profile lifting rod 1 is one.

[0023] The small suction cup 4 is a contact type small suction cup, which will work only when it is in full contact with the transported material and will not work if it is not in full contact with the transported material, and does not require any other operation.

[0024] A valve core 11 is provided on the upper side of the small suction cup 4 to control the suction and separation of the small suction cup 4 and the transported material.

[0025] The air pump assembly includes a protective shell 6 , in which an air pump body 7 is arranged.

[0026] The end of the profile lifting rod 1 is provided with a handle 5.

[0027] The working principle of the present application is that the present application adopts a profile steel with a gas flow channel 2 arranged in the longitudinal direction as the profile lifting rod 1. Such a profile lifting rod 1 has high strength and reduces the use of hoses, which not only saves costs but also avoids the problem of air leakage caused by hose damage. The small suction cup 4 is connected to the gas flow channel 2, so that the small suction cup 4 has a more stable adsorption effect on the tiles. In addition, the number of small suction cups 4 is greater than two. By replacing the conventional large suction cup with multiple small suction cups, there are more points of action. If the force exerted by a single suction cup on the tile changes or fails, the stable transportation of the tile can still be achieved. A handle 5 is provided at the end of the profile lifting rod 1, which is more convenient for applying force. When sucking tiles, air is sucked out by the vacuum pump assembly. The vacuum pump 7 can suck air from the small suction cup through the gas flow channel 2, so that the small suction cup can stably suck the tiles. The present application adopts multiple groups of small suction cups to replace large and small suction cups, so that the adsorption force of the plate lifter is more evenly distributed, which can improve the suction stability. The small suction cup 4 is a contact type small suction cup. It will work only when it contacts the object (complete contact). If there is no contact or the bottom of the suction cup is not completely in contact, the suction cup will not work. It does not require any other operation and can automatically check and intelligently absorb. Figure 4-5 Schematic diagram of the structure of two small suction cups.

[0028] Example 2. On the basis of Example 1, the number of profile lifting rods is greater than or equal to two, adjacent profile lifting rods 1 are fixedly connected, and the gas flow channels 2 of adjacent profile lifting rods 1 are connected by an air pipe 8, so that heavier and larger materials can be conveniently carried. Adjacent profile lifting rods 1 can be connected together by welding, screw connection, etc., which has better applicability.
