Description

Technical Field

[0001] This application relates to the field of steel coil transportation technology, and more particularly to a gantry assembly and forklift for transporting steel coils. Background Technology

[0002] During the transportation of steel coils, the forklift must be moved back and forth to insert its forks into the central gap of the coil drum, allowing for smooth lifting and safe transport. However, this method of transportation, relying on the forklift's back-and-forth movement, carries certain risks. If the operator is not skilled or attentive, the forklift may move improperly, causing it to collide with the steel coil. This not only damages the coil but also poses a serious safety threat to the operator and the surrounding environment. Utility Model Content

[0003] The purpose of this utility model is to solve the above-mentioned problems by providing a gantry assembly and forklift for transporting steel coils.

[0004] The technical solution of this application is implemented as follows:

[0005] In a first aspect, this application provides a gantry assembly for transporting steel coils, the gantry assembly comprising:

[0006] The gantry frame, which connects to the transport vehicle;

[0007] A mounting bracket and a supporting cylinder are provided, wherein the mounting bracket is mounted on the gantry frame and the supporting cylinder is located on the mounting bracket.

[0008] A telescopic cylinder is slidably fitted onto the supporting cylinder;

[0009] A telescopic hydraulic cylinder is installed inside the supporting cylinder. The cylinder barrel of the telescopic hydraulic cylinder is fixed inside the supporting cylinder, and the telescopic end of the telescopic rod of the telescopic hydraulic cylinder is fixed to the telescopic cylinder.

[0010] The advantages or beneficial effects of the above technical solutions include at least the following:

[0011] Secondly, this application also provides a forklift, the front of which is equipped with the mast assembly for transporting steel coils as described above, wherein the transport vehicle includes the forklift.

[0012] The advantages or beneficial effects of the above technical solutions include at least the following:

[0013] By installing a specially designed telescopic cylinder device at the front of the forklift, which can extend forward and backward as well as move laterally, the operator only needs to accurately stop the forklift in front of the steel coil when lifting and transporting it. Then, through precise control of the mast assembly, the telescopic cylinder extends into the middle of the steel coil. This process eliminates the need for complex forward and backward movements of the forklift, greatly improving operational efficiency and effectively ensuring safety during production.

[0032] Reference Figure 1 A gantry assembly for transporting steel coils, the gantry assembly comprising:

[0033] The gantry frame 10 is connected to a transport vehicle, which includes transport equipment such as forklifts.

[0034] Mounting bracket 20 and supporting cylinder 21, the mounting bracket 20 is mounted on the gantry frame 10, and the supporting cylinder 21 is located on the mounting bracket 20, such as Figure 2 As shown;

[0035] The telescopic cylinder 30 is slidably sleeved on the supporting cylinder 21, and the telescopic cylinder 30 can move back and forth along the axial direction of the supporting cylinder 21.

[0036] Telescopic cylinder 211 is installed inside the supporting cylinder 21. The cylinder barrel of telescopic cylinder 211 is fixed inside the supporting cylinder 21, and the telescopic end of the telescopic rod of telescopic cylinder 211 is fixed to the telescopic cylinder 30. Figure 7 As shown, when it is necessary to transport steel coils, the telescopic rod of the telescopic cylinder 211 moves forward, thereby driving the telescopic cylinder 30 to move forward and insert into the middle of the steel coil. After the mounting frame 20 is lifted by the gantry frame 10, the telescopic cylinder 211 can retract the telescopic rod to move the telescopic cylinder 30 backward, thus completing the retrieval of the steel coil.

[0037] The lubrication cylinder 40 is sleeved on the support cylinder 21 and located between the telescopic cylinder 30 and the support cylinder 21. The outer wall of the lubrication cylinder 40 has a spiral groove 41 extending spirally along the outer wall. The spiral groove 41 is filled with lubricating oil. When the telescopic cylinder 30 moves back and forth, the lubricating oil is driven by the inner wall of the telescopic cylinder 30 and thus driven out of the spiral groove 41, filling the entire surface of the lubrication cylinder 40, making the movement of the telescopic cylinder 30 smoother. The spiral groove 41 can increase the surface area of ​​the lubrication cylinder 40.

[0038] Based on the further improvement of the above structure, a number of oil injection holes 31 are installed on the telescopic cylinder 30 for injecting lubricating oil into the strip groove;

[0039] A first fixing plate 212 is fixed to the inner wall of the supporting cylinder 21. A pin positioning block 213 is installed on the first fixing plate 212, and a pin hole 2131 is opened on the pin positioning block 213. The cylinder of the telescopic cylinder 211 has a fixing pin 2111, which is inserted into the pin hole 2131. Figure 6 and Figure 9 As shown, the cylinder end of the telescopic cylinder 211 is fixed in this way. Since the front end of the support cylinder is an open structure, the first fixing plate 212 is close to the front end of the support cylinder. This arrangement facilitates the installation of the telescopic cylinder 211.

[0040] Meanwhile, a second fixing plate 2112 is fixed at the end of the telescopic rod away from the cylinder. The second fixing plate 2112 is fixed to the telescopic cylinder 30 by bolts. Figure 3 and Figure 4As shown, the second fixed plate 2112 serves as a transfer mechanism. At the same time, several fixed points are evenly distributed in a ring on the second fixed plate 2112, which can evenly distribute the pulling and pushing forces of the second fixed plate 2112 on the telescopic cylinder 30, and also facilitate the installation of the telescopic cylinder 30.

[0041] Based on further improvements to the above structure, in order to make the transportation of steel coils more flexible, the mounting frame 20 is movably mounted on the gantry frame 10. The mounting frame 20 can move back and forth along the width direction of the transport vehicle; thereby driving the entire telescopic cylinder 30 to move in the width direction of the transport vehicle, which is convenient for adapting to steel coils in different placement situations and increasing the flexibility of the vehicle. Specifically, two transverse hydraulic cylinders 13 are mounted on the gantry frame 10, and the telescopic ends of the two transverse hydraulic cylinders 13 face opposite directions; wherein, the cylinder barrel of the transverse hydraulic cylinder 13 is mounted on the gantry frame 10, and the telescopic end is mounted on the mounting frame 20, as shown. Figure 1 As shown, the two transverse cylinders 13 are of the same model. The mounting bracket 20 is moved laterally by one transverse cylinder 13 pushing out and the other transverse cylinder 13 retracting.

[0042] Based on the further improvement of the above structure, an upper sliding groove 11 and a lower sliding groove 12 are also provided on the gantry frame 10; and the mounting bracket 20 has a first sliding buckle 22 and a second sliding buckle 23; wherein the first sliding buckle 22 is movably embedded in the upper sliding groove 11 and the second sliding buckle 23 is movably embedded in the lower sliding groove 12, which makes the lateral movement of the mounting bracket 20 smoother.

[0043] An embodiment of this utility model also provides a forklift, the front of which is equipped with the aforementioned mast assembly for transporting steel coils. The transport vehicle includes the forklift, and the implementation effect of the forklift has been clearly described above, so it will not be repeated here.

They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0045] Those skilled in the art should understand that the above embodiments are merely for illustrative purposes and are not intended to limit the scope of this application. Those skilled in the art can make other changes or modifications based on the above disclosure, and these changes or modifications still fall within the scope of this application.
