Description

Technical Field

[0001] The utility model relates to the technical field of uncoilers, in particular to a hydraulic uncoiler. Background Technique

[0002] A hydraulic uncoiler is an important industrial equipment, mainly used to support coiled plates and provide tension to steel strips. The working principle of the hydraulic uncoiler is to push the expansion and contraction of the reel through hydraulic pressure to realize the uncoiling and reeling of the coiled plates.

[0003] For the existing hydraulic uncoilers, when transporting steel coils, they cannot fix the moving steel coils, which may cause the steel coils to roll down, affect the damage of the steel coils and even cause personal injuries. Moreover, one end of the reel of the existing hydraulic uncoiler is often suspended. Although this design simplifies the structure to a certain extent, the suspended reel is prone to bending deformation when bearing the weight of the material and the uncoiling tension, affecting the flatness of the material and the uncoiling accuracy.

[0029] Embodiment 1

[0030] like Figure 1-3 As shown, in the present embodiment, the material transport trolley 200 comprises: a support seat 210, two opposite side walls are each provided with two moving wheels 211, the surface of the moving wheel 211 is in contact with the inner wall of the slide rail 112, and the interior of the support seat 210 is symmetrically fixedly connected with four hydraulic cylinders 212; a material discharge platform 220, the bottom surface and the top of the four hydraulic cylinders 212 are fixedly connected, two opposite outer side walls of the material discharge platform 220 are symmetrically fixed with two connecting blocks 221, a rotating rod 222 is rotatably connected between the two connecting blocks 221, the outer walls of the two rotating rods 222 are both sleeved and fixed with two arc-shaped baffles 223, and the arc-shaped baffles 223 on the two rotating rods 222 are symmetrical with each other, and the outer wall of the material discharge platform 220 is symmetrically fixedly connected with two motor seats 230, the inner walls of the two motor seats 230 are both sleeved and fixed with motors 231, and the motor shafts of the two motors 231 are respectively transmission-connected to one end of the two rotating rods 222.

[0031] In this embodiment, the steel coil is placed on the top surface of the unloading table 220, and the motor 231 is started, so that the motor shafts of the two motors 231 are respectively transmitted to the rotating rods 222 connected thereto, so that the arc-shaped baffles 223 that are sleeved and fixed on the outer walls of the two rotating rods 222 and symmetrical to each other rotate toward each other, thereby forming a protective fence around the steel coil on the unloading table 220 to prevent the steel coil from falling when the material transport cart 200 moves along the slide rail 112.

[0032] like Figure 2 and Figures 4-5As shown in the figure, in this embodiment, an extension rod 113 is fixedly connected to the end of the winding drum 110. A docking groove 1131 is provided on the outer wall of the extension rod 113. The support mechanism 300 includes a first fixed seat 310 and a second fixed seat 314. The first fixed seat 310 and the second fixed seat 314 are respectively fixedly connected to two opposite outer side walls of the base 111. A third hydraulic cylinder 320 is rotatably connected to the top surface of the second fixed seat 314. The top end of the third hydraulic cylinder 320 is fixedly connected to an electric telescopic rod 322. A gear ring 321 is fixedly sleeved on the outer wall of the third hydraulic cylinder 320. A second hydraulic cylinder 311 is fixedly connected to the top surface of the first fixed seat 310. The top end of the second hydraulic cylinder 311 is fixedly connected to a rectangular block 312. A plugging hole 313 into which the end of the electric telescopic rod 322 is plugged is provided on the side wall of the rectangular block 312 close to the electric telescopic rod 322.

[0034] Embodiment Two

[0035] On the basis of Embodiment One, in order to make up for the defect that in the process of the material handling trolley 200 transporting the steel coil, the support mechanism 300 will block the traveling route of the material handling trolley 200.

[0037] During specific implementation, after the steel coil is placed on the material handling trolley 200 but before it moves, control the electric telescopic rod 322 to contract, so that the output end of the electric telescopic rod 322 is no longer inserted into the insertion hole 313. At this time, start the second motor 315. The motor shaft of the second motor 315 drives the gear 316, so that the gear 316 and the gear ring 321 mesh and drive, so that the gear ring 321 drives the hydraulic cylinder three 320 and the electric telescopic rod 322 on the hydraulic cylinder three 320 to deflect, so that the electric telescopic rod 322 no longer blocks the advancing route of the material handling trolley 200. At this time, drive the material handling trolley 200 to drive the steel coil to move forward along the slide rail 112 towards the winding drum 110. After the steel coil is sleeved on the winding drum 110, the material handling trolley 200 can be controlled to return to the initial position, and then the second motor 315 is started to rotate the hydraulic cylinder three 320 to drive the electric telescopic rod 322 to the original position, so that the output end of the electric telescopic rod 322 is aligned with the insertion hole 313, and control the electric telescopic rod 322 to extend, so that the output end of the electric telescopic rod 322 is inserted into the insertion hole 313. Finally, control the hydraulic cylinder three 320 and the hydraulic cylinder two 311 to extend so that the support block 332 supports the winding drum 110.
