Description

Technical Field

[0001] This invention relates to the field of roll material transportation technology, and more specifically to a load-bearing and transfer device for rolls. Background Technology

[0002] A coil handling vehicle is an industrial handling equipment specifically designed for handling heavy coils such as steel coils, aluminum coils, copper coils, and cable coils. Chinese patent publication number CN215398705U discloses a coil handling vehicle, which includes a vehicle body with a mast in the middle of the vehicle body. A support arm for supporting the coil is lifted and installed on one side of the mast. The support arm is horizontally arranged, and a limiting component is provided on the upper side of the support arm to restrict the movement of the coil. The support arm supports the coil, and the lifting and lowering of the coil is achieved by lifting the support arm. By setting the limiting component on the support arm to restrict the movement of the coil, the coil is prevented from slipping during the handling process, thus achieving reliable handling of the coil.

[0003] However, the inventors discovered that during the handling of the wire roll, when the equipment brakes suddenly or experiences a bump, it generates inertia, and the wire roll is prone to tipping over, causing product damage and posing a safety hazard to the workers. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a load-bearing and transporting device for a reel. By rotating a first support roller, the device works in conjunction with a second support roller to switch the fixed state of the reel. Simultaneously, when the reel tends to move forward due to inertia, an adjusting component moves the second support roller away from the first support roller, increasing the distance between them. This causes the reel to tend to move downward, counteracting the forward force caused by inertia and making the reel more stable.

[0005] The technical solution of the present invention is as follows:

[0006] A load-bearing and transporting device for a reel includes a base, on which support arms are symmetrically arranged. A drive assembly and a first support roller driven by the drive assembly are arranged between the support arms. A load-bearing arm is arranged on one side of each support arm, and a second support roller is slidably arranged on the load-bearing arm. An adjustment assembly is arranged between the first and second support rollers. The drive assembly is used to drive the first support roller to rotate, and then cooperates with the second support roller to switch the fixed state of the reel. The adjustment assembly is used to adjust the distance between the first and second support rollers according to the gravity difference between them.

[0007] As a preferred embodiment, the drive assembly includes a fixed plate fixedly disposed between the support arms, a first hydraulic cylinder fixedly disposed on the fixed plate, an extension plate fixedly disposed on the output shaft of the first hydraulic cylinder, a clamping plate fixedly disposed on the support arms, a rotating plate rotatably disposed on the clamping plate, a connecting rod hinged between the rotating plate and the extension plate, and a spring fixedly disposed between the extension plate and the fixed plate, wherein the rotating plate is fixedly connected to the first support roller.

[0008] As a preferred embodiment, the adjustment assembly includes a first gravity sensor and a second gravity sensor respectively disposed on the first support roller and the second support roller, a second hydraulic cylinder fixedly disposed on the load-bearing arm, a slide groove formed on the load-bearing arm, a limiting groove formed on the slide groove, a slide plate slidably disposed in the slide groove, and a limiting plate slidably disposed in the limiting groove. The slide plate is fixedly connected to the second support roller, and the slide plate is fixedly connected to the limiting plate.

[0009] As a preferred embodiment, both the support arm and the load-bearing arm are rotatably equipped with brackets, and each bracket is rotatably equipped with rollers.

[0010] As a preferred embodiment, both the first gravity sensor and the second gravity sensor are electrically connected to the controller, and the second hydraulic cylinder is electrically connected to the controller.

[0011] As a preferred embodiment, the movement distance of the limiting plate within the limiting groove is set between 2cm and 3cm.

[0012] As a preferred embodiment, both the first and second support rollers are provided with a rubber layer.

[0013] As a preferred embodiment, both the limiting plate and the sliding plate are provided with rounded corners.

[0014] The beneficial effects of this invention are as follows:

[0015] 1. The present invention is provided with a drive component, which uses the rotation of the first support roller to switch the fixed state of the roll in conjunction with the second support roller, so as to facilitate the transportation of the roll.

[0016] 2. The present invention also includes an adjustment component, which adjusts the distance between the first support roller and the second support roller by means of the gravity difference between the first gravity sensor and the second gravity sensor, so that the roller sinks down and prevents the roller from tilting forward and tipping over.

[0017] In summary, this invention has the advantages of good transportation effect and high safety factor, and is suitable for the field of coil transportation technology. Attached Figure Description

[0028] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0029] Example 1

[0030] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0031] like Figures 1 to 8As shown, a load-bearing and transporting device for a reel includes a base 1, with support arms 2 symmetrically arranged on the base 1. A drive assembly 3 and a first support roller 4 driven by the drive assembly 3 are arranged between the support arms 2. A load-bearing arm 5 is arranged on one side of the support arm 2, and a second support roller 6 is slidably arranged on the load-bearing arm 5. An adjustment assembly 7 is arranged between the first support roller 4 and the second support roller 6. The drive assembly 3 is used to drive the first support roller 4 to rotate, and then cooperates with the second support roller 6 to switch the fixed state of the reel. The adjustment assembly 7 is used to adjust the distance between the first support roller 4 and the second support roller 6 according to the gravity difference between them.

[0032] It is worth mentioning that, such as Figure 5 and Figure 6 As shown, the drive assembly 3 includes a fixed plate 31 fixedly disposed between the support arms 2, a first hydraulic cylinder 32 fixedly disposed on the fixed plate 31, an extension plate 33 fixedly disposed on the output shaft of the first hydraulic cylinder 32, a clamping plate 34 fixedly disposed on the support arms 2, a rotating plate 35 rotatably disposed on the clamping plate 34, a connecting rod 36 hinged between the rotating plate 35 and the extension plate 33, and a spring 37 fixedly disposed between the extension plate 33 and the fixed plate 31. The rotating plate 35 is fixedly connected to the first support roller 4. The output shaft of the first hydraulic cylinder 32 is initially in a retracted state. In the first state, the first support roller 4 is parallel to the support arm 2. During use, the first support roller 4 passes through the middle of the flanges at both ends of the reel until the second support roller 6 contacts the flange of the reel. Then, the output shaft of the first hydraulic cylinder 32 extends, pushing the connecting rod 36 and simultaneously driving the rotating plate 35 and the first support roller 4 to rotate to both sides until the first support roller 4 is perpendicular to the support arm 2. The first support roller 4, together with the second support roller 6, fixes the reel. When it is necessary to remove the reel, the output shaft of the first hydraulic cylinder 32 retracts, driving the first support roller 4 to rotate and reset, and the support arm 2 can then be removed from the reel.

[0033] It needs to be emphasized that, such as Figure 8As shown, the adjustment assembly 7 includes a first gravity sensor and a second gravity sensor respectively mounted on the first support roller 4 and the second support roller 6, a second hydraulic cylinder 71 fixedly mounted on the load-bearing arm 5, a slide groove 72 formed on the load-bearing arm 5, a limiting groove 73 formed on the slide groove 72, a sliding plate 74 slidably mounted in the slide groove 72, and a limiting plate 75 slidably mounted in the limiting groove 73. The sliding plate 74 is fixedly connected to the second support roller 6, and the sliding plate 74 is fixedly connected to the limiting plate 75. Only one of the two first support rollers 4 and the two second support rollers 6 needs to be equipped with a first gravity sensor and a second gravity sensor. When the first support roller 4 and the second support roller 6 fix the roller... After setting, the first support roller 4 and the second support roller 6 are evenly distributed. During use, when sudden braking or bumps occur, the reel tends to move forward due to inertia. The load on the first support roller 4 is greater than that on the second support roller 6. At this time, the values ​​of the first gravity sensor and the second gravity sensor change, and the gravity difference between them changes. If it exceeds the set gravity difference range, this signal is converted into an electrical signal, thereby driving the second hydraulic cylinder 71 to pull the second support roller 6 away from the first support roller 4, increasing the distance between the first support roller 4 and the second support roller 6, so that the reel can sink downwards, preventing the reel from tipping over, and greatly improving the stability of the reel transport.

[0034] It needs to be emphasized that, such as Figure 7 As shown, both the support arm 2 and the load-bearing arm 5 are rotatably equipped with brackets 8, and both brackets 8 are rotatably equipped with rollers 9. The brackets 8 are connected to a drive device. When the roll is fixed, the brackets 8 are raised, the support arm 2 is raised, and the support arm 2 and the load-bearing arm 5 stably drive the first support roller 4 and the second support roller 6 to lift the roll.

[0035] It should be further explained that, such as Figure 8 As shown, both the first and second gravity sensors are electrically connected to the controller, the second hydraulic cylinder 71 is electrically connected to the controller, and the first and second gravity sensors are electrically connected to an external controller. When the sensor difference exceeds the set threshold, the controller outputs a relay signal to control the solenoid directional valve and control the second hydraulic cylinder 71 to work.

[0036] It is worth mentioning that, such as Figure 8 As shown, the movement distance of the limiting plate 75 within the limiting groove 73 is set between 2cm and 3cm, so that the scroll sinks while preventing the bottom surface of the scroll from rubbing against the ground.

[0037] In addition, such as Figure 8 As shown, both the first support roller 4 and the second support roller 6 are provided with a rubber layer to protect the roller.

[0038] It is worth mentioning that, such as Figure 3 and Figure 4As shown, both the limiting plate 75 and the sliding plate 74 are equipped with rounded corners, making the sliding smoother.

[0039] Work process

[0040] The first support roller 4 passes through the middle of the flanges at both ends of the reel until the second support roller 6 contacts the flange of the reel. Then, the output shaft of the first hydraulic cylinder 32 extends, pushing the connecting rod 36 and driving the rotating plate 35 and the first support roller 4 to rotate to both sides until the first support roller 4 is perpendicular to the support arm 2. The first support roller 4, together with the second support roller 6, fixes the reel. When it is necessary to remove the reel, the output shaft of the first hydraulic cylinder 32 retracts, driving the first support roller 4 to rotate and reset, and the support arm 2 can be removed from the reel. When sudden braking or bumps occur, the reel tends to move forward due to inertia. At this time, the load-bearing capacity of the first support roller 4 is greater than that of the second support roller 6. The values ​​of the first gravity sensor and the second gravity sensor change, and the gravity difference between them changes. If it exceeds the set gravity difference range, this signal is converted into an electrical signal, thereby driving the second hydraulic cylinder 71 to pull the second support roller 6 away from the first support roller 4, increasing the distance between the first support roller 4 and the second support roller 6, allowing the reel to sink downwards, preventing the reel from tipping over, and greatly improving the stability of the reel transport.
