Description

Technical Field

[0001] The present application relates to the field of ship unloaders, and in particular to a ship unloader with a flat hydraulic oil tank. Background Art

[0002] The ship unloader is a special machine used for transporting bulk materials at the wharf. It mainly includes a gantry, a trolley traveling mechanism, a conveying system and a boom pitching mechanism, wherein the boom pitching mechanism usually uses a hydraulic system as a power source.

[0003] The hydraulic oil tank of the hydraulic system of the traditional boom pitch mechanism has an approximate cubic shape. When designing the ship unloader, an additional position needs to be designed for placing the hydraulic oil tank. The hydraulic oil tank requires a large space for placement, and the traditional hydraulic oil tank design allows the hydraulic oil tank to be placed only on the gantry and not on the boom pitch mechanism that will produce a pitching action. This is because pitching will cause the oil in the hydraulic oil tank to tilt, and the oil pump will not be able to pump oil or the oil will overflow. Therefore, in the overall design, space for the hydraulic oil tank needs to be reserved on the gantry, so that a position for the hydraulic oil tank needs to be reserved on the gantry, resulting in the need to change lanes in the material transportation channel in order to avoid the hydraulic oil tank, which will interfere with the transportation of materials. Utility Model Content

[0004] In order to solve the problem that the hydraulic oil tank of a conventional ship unloader occupies a large amount of space on the gantry, the present application provides a ship unloader with a flat hydraulic oil tank.

[0005] The ship unloader with a flat hydraulic oil tank provided in the present application adopts the following technical solution:

[0006] A ship unloader with a flat hydraulic oil tank comprises a ship unloader body and a hydraulic oil tank, wherein the length-to-height ratio of the hydraulic oil tank is 10-15:1, and the hydraulic oil tank is installed on a horizontal beam of the ship unloader.

[0007] After the length-to-width ratio of the hydraulic oil tank is designed to be the above-mentioned ratio, although the hydraulic oil tank installed on the horizontal beam will pitch along with the horizontal beam, the depth of the entire hydraulic oil in the hydraulic oil tank can always be maintained at a level that submerges the oil inlet pipe of the oil pump. At the same time, the depth of the oil in the tank will not be too deep, so that the oil will not overflow from the oil inlet pipe of the oil pump due to excessive oil pressure. The installation of the hydraulic oil tank will not take up space on the gantry, and the hydraulic system can work normally.

[0008] Optionally, the hydraulic oil tank has an aspect ratio of 1-2:1, the hydraulic oil tank is installed at the tail of the horizontal beam of the ship unloader body, and the length direction of the hydraulic oil tank is parallel to the length direction of the counterweight at the tail of the horizontal beam of the ship unloader.

[0009] The hydraulic oil tank is placed at the tail of the horizontal beam, so that the hydraulic oil tank can replace a part of the counterweight, reducing the overall weight of the ship unloader and reducing the power consumption of the ship unloader when it is moving.

[0010] Optionally, a mounting frame is provided on the main body of the hydraulic oil tank ship unloader, and the mounting frame includes a placement frame, and at least one limiting rod is provided in the placement frame. A frame enclosed by the placement frame and the limiting rod is defined as a limiting frame, and both ends of the limiting rod are connected to the placement frame. At least two fixing columns are provided on the bottom wall of the hydraulic oil tank, and the fixing columns are inserted into the limiting frame. A fixing device is also provided on the mounting frame for fixing the fixing columns to the placement frame.

[0011] The two fixing columns of the hydraulic oil tank are inserted into the limit frame, and then the fixing columns are fixed to the placement frame by the fixing device to complete the installation of the hydraulic oil tank. The installation and disassembly of the hydraulic oil tank are relatively convenient.

[0012] Optionally, the fixing column is in the shape of a hollow column, and a cross section of the fixing column is rectangular.

[0013] The hollow cylindrical fixing column further reduces the weight of the hydraulic oil tank itself, making the installation and disassembly of the hydraulic oil tank more convenient.

[0014] Optionally, buffer openings are formed through the four vertical side walls of the fixed column, and the buffer openings correspond to the limit rod and the frame of the placement frame. A buffer block made of vibration-damping material is slidably installed in the buffer opening, and one end face of the buffer block is pressed against the frame of the placement frame or the limit rod. The end of the fixed column away from the hydraulic oil tank is an opening, and a limit plate is provided on the four vertical inner walls of the fixed column. The four limit plates are pressed against four buffer blocks in a corresponding manner, and the limit plates are fixed to the fixed column by bolts.

[0015] The buffer block is used to reduce the impact between the hydraulic oil tank, the placement frame and the limit rod when the ship unloader rotates, so that the oil in the hydraulic oil tank is more stable, and the hydraulic oil tank can be more stably fixed on the placement frame and is not easy to loosen. At the same time, by placing the fixing column first and then installing the buffer block, both the insertion of the fixing column and the tight installation of the buffer block are more convenient.

[0016] Optionally, the placement frame and the limiting rod are both formed of cylindrical tubes, and the abutting surface of the buffer block is in contact with the limiting rod or the side wall of the placement frame.

[0017] Optionally, the fixing device includes at least one fixing rod, the fixing column is penetrated by a plurality of fixing holes corresponding to the fixing rods one by one, the fixing rod slides through the fixing holes, at least three fixing studs are threadedly installed on the fixing rod, one end of the fixing stud passes through the fixing rod and respectively presses against the frame body of the placement frame and the limiting rod.

[0018] Optionally, a rubber sleeve is sleeved on one end of the fixing stud that presses against the placement frame or the limiting rod, and one end of the rubber sleeve fits tightly against the side wall of the placement frame or the side wall of the limiting rod.

[0019] In summary, the present invention designs the hydraulic oil tank into a long flat shape.

[0020] The hydraulic oil tank is installed at the tail of the horizontal beam of the ship unloader as a part of the counterweight, which reduces the overall weight of the ship unloader while the hydraulic oil tank does not occupy the space of the gantry of the ship unloader.

[0025] The following is combined with Figure 1-2 This application is described in further detail.

[0026] The present application embodiment discloses a ship unloader having a flat hydraulic oil tank 2, referring to Figure 1 , including a ship unloader body 1 and a hydraulic oil tank 2, the hydraulic oil tank 2 is flat, the ratio of the length to the width of the hydraulic oil tank 2 is 10:1, and the ratio of the height to the width of the hydraulic oil tank 2 is 1:2. The ratio between the length and the width of the hydraulic oil tank 2 can be adjusted between 10:1 and 15:1 according to actual conditions, and is not fixed and can be customized according to actual conditions.

[0027] Reference Figure 1 , the two ends of the horizontal beam of the ship unloader are defined as the head and the tail respectively, wherein the end with the counterweight block is the tail, and the remaining end is the head. The hydraulic oil tank 2 is installed at the tail of the horizontal beam of the ship unloader. Since the hydraulic oil tank 2 is installed on the horizontal beam of the ship unloader, it will not interfere with the installation of the equipment on the ship unloader body 1. At the same time, the hydraulic oil tank 2 located at the tail of the horizontal beam of the ship unloader can also serve as a part of the counterweight, reducing the overall weight of the ship unloader.

[0028] Reference Figure 1 and Figure 2 A mounting frame 3 is fixedly installed at the tail of the horizontal beam of the ship unloader body 1. The mounting frame 3 includes a rectangular placing frame 31. The placing frame 31 is fixedly installed on the tail of the horizontal beam of the ship unloader body 1. The length direction of the placing frame 31 is horizontal, and the length direction of the placing frame 31 is perpendicular to the length direction of the horizontal beam.

[0029] Reference Figure 2 The placement frame 31 has two limit rods 32 evenly spaced along its length direction. The length direction of the limit rods 32 is parallel to the width direction of the placement frame 31. Both ends of the limit rods 32 are fixedly welded to the inner wall of the placement frame 31. The frame enclosed by the limit rods 32 and the placement frame 31 is defined as a limit frame 33. The hydraulic oil tank 2 is placed on the placement frame 31, and the length direction of the hydraulic oil tank 2 is parallel to the length direction of the placement frame 31.

[0030] Reference Figure 2 Three fixing columns 34 with rectangular cross sections are welded evenly spaced along the length direction of the bottom wall of the hydraulic oil tank 2. The fixing columns 34 are in the shape of square tubes, and one end of the fixing columns 34 away from the hydraulic oil tank 2 is open. When the hydraulic oil tank 2 is placed on the placement frame 31, the three fixing columns 34 are respectively inserted into the three limit frames 33 of the placement frame 31.

[0031] Reference Figure 2 A buffer opening 342 is formed on each of the four inner walls of the fixing column 34. When the placing frame 31 is placed on the hydraulic oil tank 2, the buffer opening 342 faces the frame body of the placing frame 31 and the limiting rod 32. The limiting rod 32 and the rod body constituting the placing frame 31 are both cylindrical pipes, and are made of steel, and can also be made of other metals or alloys with excellent performance.

[0032] Reference Figure 2A rubber buffer block 4 is slidably embedded in the buffer opening 342, and four limit plates 5 are also provided in the inner cavity of the fixed column 34. The four limit plates 5 are detachably mounted on the inner wall of the fixed column 34 by bolts. The four limit plates 5 are respectively fitted and pressed against one end of the four buffer blocks 4 located in the fixed column 34. The end surface of one end of the buffer block 4 is arc-shaped and concave and fits against the inner wall of the placement frame 31 or the side wall of the limit rod 32. The limit rod 32 and the frame of the placement frame 31 are fixed to the fixed column 34 through the buffer block 4.

[0033] Reference Figure 2 The fixed column 34 is connected to the placement frame 31 through the buffer block 4. The vibration and impact exerted by the placement frame 31 on the fixed column 34 will be absorbed by the buffer block 4. Therefore, the shaking of the oil in the hydraulic oil tank 2 will be relatively slow, which has little effect on the oil pumping. At the same time, after the rubber buffer block 4 is pressed tightly by the limit plate 5, the buffer block 4 will form a seal with the buffer port 342, which can effectively prevent the bolts inside the fixed column 34 from rusting.

[0034] Reference Figure 2 The fixing column 34 passes through the lower side wall of the placement frame 31 and has two fixing holes 341. The axes of the two fixing holes 341 are located at the same level, and the axes of the fixing holes 341 are parallel to the length direction of the placement frame 31. The three fixing holes 341 on the same side of the three fixing columns 34 are coaxial, and a fixing rod 6 is slidably inserted in the fixing holes 341. Four fixing studs 7 are inserted in the fixing rod 6 at intervals along the length direction thereof, and the fixing studs 7 are threadedly connected to the fixing rod 6.

[0035] Reference Figure 2 The four fixing studs 7 correspond to the two limiting rods 32 and the two wide sides of the placement frame 31. After one end of the fixing rod 6 passes through the three fixing holes 341 in sequence, the fixing rod 6 is rotated to adjust the fixing stud 7 to be vertical, and then the fixing stud 7 is tightened until the upper end of the fixing stud 7 is pressed against the bottom wall of the placement frame 31 and the bottom wall of the limiting rod 32, thereby completing the fixing of the fixing rod 6. At the same time, a rubber sleeve 8 is sleeved on the upper end of the fixing stud 7, and the rubber sleeve 8 is rotationally connected to the fixing bolt. After the fixing bolt is pressed against the placement frame 31 and the limiting rod 32, the rubber sleeve 8 fits against the bottom wall of the placement frame 31 or the limiting rod 32.

[0036] The implementation principle of a ship unloader with a flat hydraulic oil tank 2 in the embodiment of the present application is as follows: the hydraulic oil tank 2 with a length, width and height ratio of 10:2:1 is fixed to the tail of the horizontal beam through a mounting frame 3. The hydraulic oil tank 2 does not occupy the space of the ship unloader body and can also be used as a part of the counterweight, thereby reducing the overall weight of the ship unloader.

[0037] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
