Abstract
Description
Technical Field
[0001] This utility model relates to the field of steel coil transportation technology, and in particular to a steel coil transfer vehicle with locking function. Background Technology
[0002] Steel coils are made by hot-pressing and cold-pressing steel into coils. After the steel is coiled, it needs to be transferred using a transfer vehicle. The steel coil is loaded onto a special transport vehicle and then transported to a designated transport site.
[0003] A search revealed a Chinese utility model patent (publication number: CN 221023671 U) for a steel coil transfer method. This method involves setting fixed inclined blocks on the vehicle's carrying platform. The inclined surfaces of these blocks collectively form a V-shaped groove for placing the steel coil. To prevent lateral movement of the steel coil during transport, this design is simple, robust, and durable, providing effective support and fixation for steel coils with standard shapes and uniform dimensions, thus ensuring transport safety to a certain extent. However, this design has inherent limitations. The core issue is that the angle of the supporting inclined surfaces of the blocks is fixed. This "rigid" design is based on an idealized premise that all steel coils to be transported are standard products with perfectly circular cross-sections. However, in actual warehousing and production environments, steel coils often undergo irregular deformations such as elliptical or polygonal shapes due to long-term stacking, improper lifting, or stress release. Furthermore, production lines frequently require the transfer of steel coils from different batches and with different diameters. When faced with these non-standard or varying-sized steel coils, the fixed-angle inclined blocks reveal their poor adaptability.
[0004] Therefore, it is necessary to provide a new steel coil transfer vehicle with locking function to solve the above-mentioned technical problems. Utility Model Content
[0005] To solve the above-mentioned technical problems, this utility model provides a steel coil transfer vehicle with locking function.
[0006] The steel coil transfer cart with locking function provided by this utility model includes: a car body, a distance adjustment mechanism, and a support mechanism. The car body has an installation groove, in which the distance adjustment mechanism is installed. The distance adjustment mechanism includes a first hydraulic telescopic rod, an adjusting block, and a support seat. The first hydraulic telescopic rod is installed on both inner sides of the installation groove. The output end of the first hydraulic telescopic rod is fixedly connected to the adjusting block, and the upper surface of the adjusting block is fixedly connected to the support seat. The support mechanism is installed on the support seat, and the support mechanism includes a pivot support plate, a fixing block, a second hydraulic telescopic rod, and a slider. The system comprises a first U-shaped pivot lug, a support block, and a second U-shaped pivot lug. A fixed block is fixedly connected to the upper surface of the support lug. A second hydraulic telescopic rod is installed on one side of the fixed block. A slider is fixedly connected to the output end of the second hydraulic telescopic rod. The first U-shaped pivot lug is fixedly connected to the upper surface of the slider. The support block is rotatably connected to the first U-shaped pivot lug via a pivot shaft. A pivot support plate is rotatably connected to one end of the support lug via a pivot shaft. The second U-shaped pivot lug is fixedly connected to the lower surface of the pivot support plate. The other end of the support block is rotatably connected to the second U-shaped pivot lug via a pivot shaft.
[0007] Preferably, the upper surface of the pivot support plate is provided with a rubber pad.
[0008] Preferably, both sides of the pivot support plate are fixedly connected with a plurality of evenly distributed fixing rings.
[0009] Preferably, the upper surface of the support base is provided with a groove that matches the slider, and the lower end of the slider is slidably inserted into the groove.
[0010] Preferably, the upper surface of the vehicle body has two symmetrically arranged limiting grooves, and the lower surface of the support seat is fixedly connected to two symmetrically arranged limiting strips, which are slidably inserted into adjacent limiting grooves.
[0011] Preferably, a rib is fixedly connected to one side of the fixing block, and the lower surface of the rib is fixedly connected to the upper surface of the support base.
[0012] Preferably, the adjusting block is slidably connected to the inner side of the mounting groove.
[0013] Compared with related technologies, the steel coil transfer cart with locking function provided by this utility model has the following advantages:
[0014] This utility model provides a steel coil transfer vehicle with a locking function. Through the setting of a distance adjustment mechanism and a support mechanism, not only can the distance between the two pivot support plates be adjusted, but also the angle between the two pivot support plates can be adjusted. The steel coil can be firmly "embedded" into a custom-made V-shaped groove by the two adjustable pivot support plates for locking. The adjustable pivot support plates can "follow" the deformed contour to find the optimal support cross-section. Therefore, it can not only be used for standard round steel coils, but also perfectly support steel coils that have undergone elliptical deformation due to long-term stacking or improper hoisting. Moreover, regardless of whether the steel coil is large or small in diameter, the support surface can always be in the optimal support position by adjusting the angle, avoiding problems such as poor contact of small steel coils or improper support points of large steel coils. For some special coils with protrusions or depressions on the surface, the adjustable angle can compensate for them and find the most stable support method, thereby greatly improving the versatility of the vehicle and the asset utilization rate.

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0020] Please refer to the following: Figure 1 , Figure 2 and Figure 3 ,in, Figure 1 This is a schematic diagram of the structure of this utility model;
[0021] Figure 2 This is a schematic diagram of the vehicle body structure in this utility model; Figure 3 This is a schematic diagram of the support base in this utility model. It includes: a vehicle body 1 (the vehicle body 1 is an existing device and will not be described in detail here), a distance adjustment mechanism, and a support mechanism.
[0022] refer to Figure 1 , Figure 2 and Figure 3 As shown, the vehicle body 1 has an installation groove 15, and a distance adjustment mechanism is installed in the installation groove 15. The distance adjustment mechanism includes a first hydraulic telescopic rod 16, an adjustment block 17, and a support seat 2. The first hydraulic telescopic rod 16 is installed on both inner sides of the installation groove 15. The output end of the first hydraulic telescopic rod 16 is fixedly connected to the adjustment block 17. The upper surface of the adjustment block 17 is fixedly connected to the support seat 2, and a support mechanism is installed on the support seat 2.
[0023] It should be noted that when in use, the steel coil is placed between the two support mechanisms on the vehicle body 1. The extension and retraction of the first hydraulic telescopic rod 16 can drive the adjusting block 17 to slide in the mounting groove 15. The movement of the adjusting block 17 drives the translation of the support seat 2. The movement of the support seat 2 drives the movement of the support mechanism on it, thereby adjusting the distance between the two support mechanisms.
[0024] refer to Figure 1 As shown, the support mechanism includes a pivot support plate 8, a fixed block 3, a second hydraulic telescopic rod 4, a slider 5, a first U-shaped pivot lug 6, a support block 7, and a second U-shaped pivot lug 9. The upper surface of the support base 2 is fixedly connected to the fixed block 3. The second hydraulic telescopic rod 4 is installed on one side of the fixed block 3. The output end of the second hydraulic telescopic rod 4 is fixedly connected to the slider 5. The upper surface of the slider 5 is fixedly connected to the first U-shaped pivot lug 6. The support block 7 is rotatably connected to the first U-shaped pivot lug 6 via a pivot shaft. One end of the support base 2 is rotatably connected to the pivot support plate 8 via a pivot shaft. The lower surface of the pivot support plate 8 is fixedly connected to the second U-shaped pivot lug 9. The other end of the support block 7 is rotatably connected to the second U-shaped pivot lug 9 via a pivot shaft.
[0025] It should be noted that during use, the extension and retraction of the second hydraulic telescopic rod 4 can drive the movement of the slider 5. Since the pivot support plate 8 is rotatably connected to one end of the support base 2 via a pivot shaft, and the two ends of the support block 7 are respectively rotatably connected to the first U-shaped pivot lug 6 and the second U-shaped pivot lug 9 via pivot shafts, when the slider 5 moves horizontally, the pivot support plate 8 rotates around its pivot shaft, and the angle changes. The operator can visually observe that the pivot support plates 8 on both sides are in maximum close contact with the outline of the steel coil. Then, the second hydraulic telescopic rod 4 is stopped. The self-locking effect of the second hydraulic telescopic rod 4 will keep the pivot support plate 8 stably maintained at the current angle. At this time, the steel coil has been firmly "embedded" into a custom-made V-shaped groove by the adjustable pivot support plate 8 and locked. It is then tied and fixed with ropes.
[0026] refer to Figure 1 As shown, the upper surface of the pivot support plate 8 is provided with a rubber pad 11, which protects the pivot support plate 8.
[0027] refer to Figure 1 As shown, multiple evenly distributed fixing rings 10 are fixedly connected to both sides of the pivot support plate 8, which facilitates rope binding.
[0028] refer to Figure 1 As shown, the upper surface of the support base 2 is provided with a groove 13 that matches the slider 5. The lower end of the slider 5 is slidably inserted into the groove 13. The groove 13 serves as a limit, making the movement of the slider 5 more stable.
[0029] refer to Figure 2 and Figure 3 As shown, the upper surface of the vehicle body 1 has two symmetrically arranged limiting grooves 14, and the lower surface of the support base 2 is fixedly connected to two symmetrically arranged limiting strips 18. The limiting strips 18 are slidably inserted into the adjacent limiting grooves 14. Through the limiting strips 18 and the limiting grooves 14, when the support base 2 moves, the limiting strips 18 slide in the limiting grooves 14, which plays a limiting role and makes the movement of the support base 2 more stable.
[0030] refer to Figure 1 As shown, a rib 12 is fixedly connected to one side of the fixing block 3. The lower surface of the rib 12 is fixedly connected to the upper surface of the support base 2. The rib 12 makes the structure of the fixing block 3 more stable.
[0031] refer to Figure 2 As shown, the adjusting block 17 is slidably connected to the inner side of the mounting groove 15. When the adjusting block 17 moves, it slides in the mounting groove 15, which plays a limiting role and makes the movement of the adjusting block 17 more stable.
[0032] The working principle of this utility model is as follows: During use, the steel coil is placed between two support mechanisms on the vehicle body 1. The extension and retraction of the first hydraulic telescopic rod 16 causes the adjusting block 17 to slide within the mounting groove 15. The movement of the adjusting block 17 causes the support seat 2 to move horizontally, and the movement of the support seat 2 causes the support mechanism on it to move, thereby adjusting the distance between the two support mechanisms, i.e., adjusting the distance between the two pivot support plates 8. This facilitates the transfer and use of steel coils of different diameters, improving the applicability of the device. During use, the extension and retraction of the second hydraulic telescopic rod 4 causes the slider 5 to move. Since the pivot support plate 8 is rotatably connected to one end of the support seat 2 via a rotating shaft, and both ends of the support block 7 are rotatably connected to the first U-shaped pivot ear 6 and the second U-shaped pivot ear 9 via rotating shafts respectively, when the slider 5 moves horizontally, the pivot support plate 8 rotates around its rotating shaft, changing the angle. The operator can visually observe this, allowing the pivot support plates 8 on both sides to rotate. All components are tightly fitted to the contour of the steel coil with the maximum area. Then, the second hydraulic telescopic rod 4 is stopped. The self-locking effect of the second hydraulic telescopic rod 4 will keep the pivot support plate 8 stably maintained at the current angle. At this time, the steel coil has been firmly "embedded" into a custom-made V-groove by the adjustable pivot support plate 8 and locked. The adjustable pivot support plate 8 can "follow" the deformed contour and find the best support surface. Therefore, it can not only be used for standard round steel coils, but also perfectly support steel coils that have undergone elliptical deformation due to long-term stacking or improper hoisting. Moreover, whether it is a large-diameter or small-diameter steel coil, the angle can be adjusted to keep the support surface in the best support position, avoiding the problems of poor contact of small steel coils or improper support points of large steel coils. For some special coils with protrusions or depressions on the surface, the adjustable angle can compensate and find the most stable support method, thereby greatly improving the versatility of the vehicle and the asset utilization rate. Then, it is tied and fixed with ropes.
[0033] In this utility model, both the first hydraulic telescopic rod 16 and the second hydraulic telescopic rod are connected to a standard hydraulic system via pipelines to achieve their extension and retraction control (the first hydraulic telescopic rod 16 and the second hydraulic telescopic rod are connected to a hydraulic pump station via pipelines to obtain power, and the flow direction of hydraulic oil is switched by operating the reversing valve on the pipeline, thereby controlling the extension or retraction of the telescopic rod). The specific settings of this hydraulic system are conventional technology in this field. In addition, the circuits and controls involved in this utility model are all existing technologies and will not be described in detail here.
[0034] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
