Description

Technical Field

[0001] The present application relates to the technical field of chutes, and in particular to a square lifting chute used in a ship loader. Background Art

[0002] Ship loader is a device used to transport goods from the dock or shore to the ship. The lifting chute of the ship loader is an important part of the ship loader, which is used to transport goods from the dock to the ship or from the ship to the dock. The lifting chute is usually located at the top of the ship loader, and its main function is to provide a stable channel so that the goods can be safely transported up and down.

[0003] The widely used lifting chutes of ship loaders are usually circular in design, and their cylinder diameter usually matches the diameter of the hopper flange ring to ensure a smooth cargo transportation process. However, this design presents some challenges when it comes to damage. It is relatively difficult to repair a damaged cylinder, and it is usually necessary to fold the steel plate into an arc. This repair work requires superb technology and professional equipment. The repaired cylinder often loses its original round shape and may become irregular in shape, which can cause friction or resistance during the lifting process, affecting the smooth progress of loading and unloading operations, and even causing the lifting system to fail.

[0004] Therefore, it is necessary to provide a square lifting chute used by a ship loader to solve the above problems.

[0005] It should be noted that the above information disclosed in this background technology section is only for understanding the background technology of the present application concept, and therefore, it may contain information that does not constitute the prior art. Utility Model Content

[0006] Based on the above problems existing in the prior art, the problem to be solved by the present application is: to provide a square lifting chute used in a ship loader, so as to achieve the effect of convenient maintenance and prevention of lifting failure.

[0007] The technical solution adopted by the present application to solve the technical problem is: a square lifting chute used in a ship loader, comprising an inner cylinder, a middle cylinder and an outer cylinder, wherein the inner cylinder, the middle cylinder and the outer cylinder are in a square shape;

[0008] A transition body is provided on the top of the inner cylinder, and a flange ring is provided on the top of the transition body. A first lifting ear is provided on the outer side of the inner cylinder, a second lifting ear and a third lifting ear are provided on the outer side of the middle cylinder, a first chain is provided between the first lifting ear and the second lifting ear, a fourth lifting ear is provided on the outer side of the outer cylinder, and a second chain is provided between the third lifting ear and the fourth lifting ear. A steel wire traction rope is connected to the outer side of the outer cylinder, and one end of the steel wire traction rope is connected to the traction machine on the ship loader.

[0009] Furthermore, the bottom of the adapter is square and fixedly connected to the inner tube, and the top of the adapter is annular and has a flange ring at the upper end of the top surface.

[0010] Furthermore, the middle tube is located outside the inner tube, and the outer tube is located outside the middle tube.

[0011] Furthermore, four groups of the first lifting ears and the second lifting ears are arranged at equal intervals along the outer sides of the inner tube and the middle tube, and four groups of the first chains are arranged, respectively used to connect the first lifting ears and the second lifting ears.

[0012] Furthermore, four groups of the third lifting ears and the fourth lifting ears are arranged at equal intervals along the outer sides of the middle tube and the outer tube, and four groups of the second chains are arranged, respectively used to connect the third lifting ears and the fourth lifting ears.

[0013] Furthermore, a connecting column is fixedly provided on the outer side of the outer cylinder, and the steel wire traction rope is connected to the connecting column.

[0014] Furthermore, the inner tube, the middle tube and the outer tube are all made of rigid material.

[0015] The beneficial effect of the present application is that the square lifting chute used in the ship loader provided by the present application does not need to bend the cylinder into an arc during maintenance due to the design of the square inner cylinder, middle cylinder and outer cylinder, thereby avoiding the situation of loss of roundness after folding and preventing the lifting failure after repair. Compared with the cylindrical body, it is more convenient to maintain, and the inner cylinder, middle cylinder and outer cylinder are connected with the first chain and the second chain, so no matter which cylinder is damaged, it can be easily disassembled for maintenance and replacement, which is more cost-effective than replacing the whole cylinder, and the inner cylinder, middle cylinder and outer cylinder made of steel plates are more wear-resistant. At the same time, the setting of the first chain and the second chain can prevent the middle cylinder and the outer cylinder from accidentally falling, thereby further improving the safety of loading and unloading.

[0025] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0026] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0027] like Figures 1 to 5As shown, the present application provides a square lifting chute for a ship loader, comprising an inner cylinder 1, a middle cylinder 2 and an outer cylinder 3. The inner cylinder 1, the middle cylinder 2 and the outer cylinder 3 are all square in shape, with an inner cylinder diameter of 1200 mm, a middle cylinder 1 diameter of 1240 mm, and an outer cylinder 3 diameter of 1280 mm. They are all made of a steel plate with a thickness of 10 mm. The inner cylinder 1, the middle cylinder 2 and the outer cylinder 3 are all 2 meters high. A switching body 11 is provided on the top of the inner cylinder 1. The lower part of the switching body 11 is square and fixedly connected to the inner cylinder 1 by welding. The top of the switching body 11 is annular and a flange ring 13 is provided on its upper end. The flange ring 13 is used to connect to the bottom flange of the ship loader hopper. A first lifting ear 12 is provided on the outer side of the inner cylinder 1, and a second lifting ear 21 is provided on the outer side of the middle cylinder 2. The first lifting ear 12 is provided on the outer side of the inner cylinder 1, and a second lifting ear 21 is provided on the outer side of the middle cylinder 2. There are four groups of ears 12 and second ears 21, and first chains 4 are respectively arranged between the four groups of first ears 12 and the four groups of second ears 21. The first chain 4 is used to connect the first ears 12 and the second ears 21. A third ear 22 is also arranged on the outside of the middle tube 2, and a fourth ear 31 is arranged on the outside of the outer tube 3. There are four groups of third ears 22 and fourth ears 31, and second chains 5 are respectively arranged between the four groups of third ears 22 and the four groups of fourth ears 31. The second chain 5 is used to connect the third ear 22 and the fourth ear 31. The diameters of the first chain 4 and the second chain 5 are both 8 mm. A connecting column 32 is arranged on the outside of the outer tube 3, and a steel wire traction rope 6 is connected to the connecting column 32. One end of the steel wire traction rope 6 is connected to a traction machine installed on the ship loader.

[0028] In this embodiment, the flange ring 13 is used to facilitate the connection of the chute as a whole with the flange at the bottom of the hopper of the ship loader, so that the inner cylinder 1 is fixed to the lower end of the hopper, and the wire traction rope 6 is unwound by the traction machine. Under the action of gravity, the middle cylinder 2 and the outer cylinder 3 move downward along the outer side of the inner cylinder 1, and the downward movement of the middle cylinder 2 drives the second lifting ear 21 to move downward, so that the first chain 4 is deformed as a whole. When the first chain 4 reaches the longest distance, the middle cylinder 2 stops descending under the pulling of the first chain 4. At this time, the traction machine continues to unwind, so that the outer cylinder 3 continues to move downward, and the outer cylinder 3 drives the fourth lifting ear 31 to move downward, so that the second chain 5 is deformed. When the second chain 5 reaches the longest distance, the outer cylinder 3 stops descending under the drag of the second chain 5. At this time, the traction machine is stopped, and the material can be filled into the inner cylinder 1 through the loader hopper. The material passes through the inner cylinder 1, the middle cylinder 2 and the outer cylinder 3 and finally reaches the position where the material needs to be loaded. Through the setting of the first chain 4 and the second chain 5, not only the descending range of the middle cylinder 2 and the outer cylinder 3 can be limited, but also the phenomenon of the middle cylinder 2 and the outer cylinder 3 falling can be prevented. When the material fills the outer wall, the traction machine reels in the wire traction rope 6, and the wire traction rope 6 drives the outer cylinder 3 to move upward, so that the second chain 5 is released. When the top of the outer cylinder 3 contacts the second lifting lug 21 and the third lifting lug 22, the outer cylinder 3 is blocked by the second lifting lug 21 and the third lifting lug 22. As the traction machine continues to reel in the steel wire traction rope 6, the outer cylinder 3 drives the middle cylinder 2 to move upward through the second lifting lug 21 and the third lifting lug 22. When the top of the middle cylinder 2 contacts the first lifting lug 12, the traction machine is stopped to complete the contraction of the entire cylinder and return it to its initial state. With the design of the square inner cylinder 1, the middle cylinder 2 and the outer cylinder 3, it is not necessary to fold the cylinder into an arc during maintenance, thereby avoiding the situation of losing the round after folding. The inner cylinder 1, the middle cylinder 2 and the outer cylinder 3 are connected by the first chain 4 and the second chain 5. No matter which cylinder is damaged, it can be easily disassembled for repair and replacement, which is more cost-effective than replacing the entire cylinder. The inner cylinder 1, the middle cylinder 2 and the outer cylinder 3 made of steel plates are more wear-resistant. At the same time, the first chain 4 and the second chain 5 can prevent the middle cylinder 2 and the outer cylinder 3 from falling accidentally, further improving the safety of loading and unloading.

[0029] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
