Description
Technical Field
[0001] This utility model belongs to the field of metal stacking auxiliary tool design technology, specifically relating to a stacking limiting device suitable for large-mass metal elements. Background Technology
[0002] Traditional methods for stacking large-mass metal sheets (weighing no less than 700 kg) using hoisting clamps often result in excessively large gaps between the edges of the upper and lower metal billets, making alignment impossible. Before stacking, manual intervention is usually required to control the alignment accuracy between different billets. However, manual stacking poses certain safety hazards. With the increasingly widespread application of large-mass metal billet stacking, manual stacking methods are no longer sufficient to meet the high precision and efficiency requirements of actual engineering projects, and suffer from low stacking accuracy and poor efficiency. Utility Model Content
[0003] Therefore, this utility model provides a stacking limiting device suitable for large-mass metal elements, which can overcome the technical problems of low stacking accuracy and poor efficiency in the traditional manual stacking method.
[0004] To address the aforementioned problems, this utility model provides a stacking limiting device suitable for large-mass metal elements, comprising two limiting components arranged at relative intervals. Each limiting component includes a limiting frame, the distance between the two limiting frames can be controlled and adjusted, and each limiting frame has a limiting groove extending vertically downward from its top. The limiting groove is used for rolling limiting connection with the limiting wheels on both sides of the load-bearing body of the clamp.
[0005] In some embodiments, the top opening of the limiting groove gradually widens from bottom to top.
[0006] In some embodiments, each of the limiting components further includes a buffer sleeve fitted outside the limiting frame, the buffer sleeve being controllable to rise and fall.
[0007] In some embodiments, the buffer sleeve includes a buffer base and a buffer cover plate on the buffer base, wherein a plurality of buffer springs are spaced apart between the buffer cover plate and the buffer base, and a buffer gap is formed between the bottom surface of the buffer cover plate and the top surface of the buffer base.
[0008] In some embodiments, the buffer sleeve is provided with a lifting drive device, which is a rotary motor. The free end of the output shaft of the lifting drive device has a lifting drive gear. A first rack portion is formed on the outer wall of the limiting frame from top to bottom. The outer wall of the limiting frame has a slide rail extending vertically. The buffer sleeve is slidably connected to the slide rail. The slide rail and the first rack portion are respectively located on opposite side walls of the limiting frame. The lifting drive gear meshes with the first rack portion to drive the buffer sleeve to rise and fall when the lifting drive device is running.
[0009] In some embodiments, the limiting component further includes a fixed base for fixed connection to the ground, the bottom end of the limiting frame is slidably and positionably connected to the top surface of the fixed base via an adapter plate, and the bottom end of the limiting frame is slidably and positionably connected to the top surface of the adapter plate.
[0010] In some embodiments, the fixed base has an accommodating space with a top opening, and a telescopic cylinder component is assembled on the fixed base. The free end of the telescopic rod of the telescopic cylinder component is fixedly connected to the adapter plate to drive the adapter plate to translate.
[0011] In some embodiments, the adapter plate has U-shaped flanges on both sides of its width that bend toward the fixed base, and the U-shaped flanges are slidably connected to both sides of the top plate of the fixed base.
[0012] In some embodiments, end limiting plates are provided at both ends of the length of the U-shaped flange.
[0013] In some embodiments, two parallel and spaced I-beam rails are integrally formed on the top surface of the adapter plate, and a corresponding I-beam groove is formed at the bottom end of the limiting frame.

The fine-tuning gear meshes with the second rack portion.
[0014] This utility model provides a stacking limiting device suitable for large-mass metal elements, which has the following features:
[0015] Beneficial effects:
[0016] The controllable adjustment of the spacing between the limiting frames of two relatively spaced limiting components enables precise lateral positioning of the clamp located between them. At the same time, the precise front-back positioning of the clamp is achieved by the rolling cooperation between the vertically extending limiting grooves on the limiting frame and the limiting wheels on both sides of the load-bearing body. This enables precise lateral and lateral positioning of the metal elements to be stacked without much manual intervention, significantly improving both stacking accuracy and stacking efficiency.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present utility model or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.
[0024] In the description of this utility model, it should be understood that the directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description. Unless otherwise stated, these directional terms 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, and therefore should not be construed as a limitation on the scope of protection of this utility model. The directional terms "inner" and "outer" refer to the inner and outer contours of each component itself.
[0025] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90° or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.
[0026] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this utility model.
[0027] See also Figures 1 to 3 As shown in the figure, according to an embodiment of the present invention, a stacking limiting device suitable for large-mass metal elements is provided, including two limiting components (not labeled in the figure) arranged relatively apart. The limiting components include limiting frames 21, the distance between the two limiting frames 21 can be controlled and adjusted, and each limiting frame 21 has a limiting groove 22 extending downward in a vertical direction from its top. The limiting groove 22 is used for rolling limiting connection with the limiting wheels 15 on both sides of the load body 11 of the clamp 1. Specifically, when stacking, the aforementioned clamp 1 is lifted in the space between the two limiting components, and at the same time, the two limiting wheels 15 on the opposite sides of the load body 11 are respectively inserted into the aforementioned limiting groove 22 to form a rolling limiting connection with the limiting groove 22.
[0028] In this technical solution, the left and right positions of the clamp 1 located between the two limiting components are precisely limited by the controllable adjustment of the distance between the limiting frame bodies 21 of the two limiting components. At the same time, the front and back positions of the clamp 1 are precisely limited by the rolling cooperation between the vertically extending limiting grooves 22 on the limiting frame bodies 21 and the limiting wheels 15 on both sides of the load-bearing body 11. Thus, the front, back, left and right positions of the metal elements to be stacked are precisely limited without much manual intervention, and the stacking accuracy and stacking efficiency can be significantly improved.
[0029] See details Figure 1 As shown, in some embodiments, the top opening of the limiting groove 22 gradually expands from bottom to top.
[0030] In this technical solution, the top opening of the limiting groove 22 is an flared structure, which facilitates the smoother alignment of the limiting wheel 15 on the fixture 1 into the limiting groove 22.
[0031] In some embodiments, each of the limiting components further includes a buffer sleeve 23 fitted outside the limiting frame 21. The buffer sleeve 23 can be controlled to rise and fall. Specifically, the buffer sleeve 23 can be controlled to fall synchronously with the height of the clamp 1 and always remain below the bottom height of the clamp 1.
[0032] In this technical solution, a buffer sleeve 23 is fitted outside the limiting frame 21, which can descend synchronously with the descent of the clamp 1. This can form a buffer support when the clamp 1 falls out of control due to a malfunction or when the metal element clamped in the clamp 1 slips off, thereby improving the safety of equipment operation.
[0033] In one specific embodiment, the buffer sleeve 23 includes a buffer base 231 and a buffer cover plate 232 on the buffer base 231. A plurality of buffer springs 233 are spaced apart between the buffer cover plate 232 and the buffer base 231. There is a buffer gap between the bottom surface of the buffer cover plate 232 and the top surface of the buffer base 231. The size of the buffer gap can be reasonably determined based on the elastic deformation of the buffer springs 233. In principle, when the metal element or clamp 1 above falls off and is supported on the buffer cover plate 232, the buffer gap still has a certain gap, that is, it is preferable that the buffer cover plate 232 and the buffer base 231 do not contact each other.
[0034] In this technical solution, by setting a buffer cover plate 232 on the top of the buffer spring 233, the pressure above it can be dispersed and uniformly distributed, thereby ensuring the effective buffer support function of the buffer sleeve 23.
[0035] In a feasible embodiment, the buffer sleeve 23 is provided with a lifting drive device 234, which is a rotary motor. The free end of the output shaft of the lifting drive device 234 has a lifting drive gear (not shown in the figure, not indexed). A first rack portion (not shown in the figure, not indexed) is formed on the outer wall of the limiting frame 21 from top to bottom. The outer wall of the limiting frame 21 has a slide rail extending vertically (not shown in the figure, not indexed). The buffer sleeve 23 is slidably connected to the slide rail. The slide rail and the first rack portion are respectively located on the opposite side wall of the limiting frame 21. The lifting drive gear meshes with the first rack portion to drive the buffer sleeve 23 to rise and fall when the lifting drive device 234 is running. It is understood that the aforementioned lifting drive device 234 is preferably a rotary motor with a braking structure (such as a brake disc or other components), so that there is no need to lock the position of the buffer sleeve 23, simplifying the structural design.
[0036] In this technical solution, the lifting and lowering control of the buffer sleeve 23 is achieved through the engagement between the lifting drive device 234 and the limit frame 21. The structure is simple and the position control is precise.
[0037] It should be noted that although using the aforementioned rotary motor to drive the lifting and lowering of the buffer sleeve 23 can achieve precise height following of the buffer sleeve 23, it is important to note that if the clamp 1 or metal element falls off, the probability of damage to the teeth between the aforementioned lifting drive gear and the first rack is relatively high. Therefore, as a better implementation method (not shown), the aforementioned lifting drive device 234 is a lifting telescopic cylinder. In this case, the lifting telescopic cylinder is fixed on the fixed base 24 described later, and the free end of the telescopic rod of the lifting telescopic cylinder is connected to the bottom side of the buffer sleeve 23. There are two lifting telescopic cylinders, and the two telescopic rods are respectively supported at both ends of the length of the buffer sleeve 23. In this way, the extension and retraction of the two lifting telescopic cylinders can be controlled to achieve the following lifting and lowering of the buffer sleeve 23. It is worth noting that in this case, the lifting telescopic cylinder achieves height adjustment control of the buffer sleeve 23 by forming a buffer support due to the damping effect of the hydraulic oil in the cylinder. The buffer sleeve 23 has a better buffering effect and a lower equipment failure rate.
[0038] In some embodiments, the limiting component further includes a fixed base 24, which is used to fix the limiting component to the ground to ensure the stability of the entire limiting component. The bottom end of the limiting frame 21 is slidably and positionably connected to the top surface of the fixed base 24 via an adapter plate 25. The bottom end of the limiting frame 21 and the top surface of the adapter plate 25 are slidably and positionably connected. The aforementioned positionable connection means that the corresponding components, such as the aforementioned limiting frame 21 and adapter plate 25, can be locked in position after being adjusted to the correct position. For example, locking can be achieved by manually setting positioning blocks or other components at the corresponding positions.
[0039] In this technical solution, the fixed base 24 and the adapter plate 25, as well as the adapter plate 25 and the limiting frame 21, are designed to be sliding and positionable (i.e., position locked). The stacking and positioning accuracy of the metal elements can be achieved by adjusting the position of the adapter plate 25 and the limiting frame 21.
[0040] In some embodiments, the fixed base 24 has an accommodating space (not shown in the figure, not indexed) and the accommodating space has a top opening (not shown in the figure, not indexed). A telescopic cylinder component 241 is assembled on the fixed base 24, and the free end of the telescopic rod of the telescopic cylinder component 241 is fixedly connected to the adapter plate 25 to drive the adapter plate 25 to translate.
[0041] In this technical solution, the telescopic cylinder component 241 enables rapid large displacement adjustment of the adapter plate 25 and the limiting frame 21 (including buffer sleeve 23, etc.) on it, ensuring that the distance between the two limiting frames 21 quickly and efficiently approaches the target distance, that is, to achieve coarse adjustment of the limiting position of the limiting frame 21.
[0042] In some embodiments, the adapter plate 25 has U-shaped flanges (not indicated in the figure) that bend toward the fixed base 24 on both sides of its width, and the U-shaped flanges are slidably connected to the top plate of the fixed base 24 on both sides of its width.
[0043] In this technical solution, the U-shaped flanges formed on both sides of the width of the adapter plate 25 are slidably connected to the top plate of the fixed base 24 to form a clamp structure, which can ensure the anti-overturning performance of the upper structure.
[0044] In some embodiments, end limiting plates 252 are provided at both ends of the length of the U-shaped flange to prevent the adapter plate 25 from displacing and detaching from the fixed base 24 due to excessive displacement adjustment.
[0045] In some embodiments, two parallel and spaced I-beam rails 251 are integrally formed on the top surface of the adapter plate 25, and a corresponding I-beam groove (not shown in the figure) is formed at the bottom end of the limiting frame 21. The I-beam rails 251 are slidably connected in the I-beam groove, and a second rack portion (not shown in the figure, not shown in the figure) is formed on the top surface of the I-beam rails 251. A pitch fine-tuning motor 26 is provided at the bottom end of the limiting frame 21, and a fine-tuning gear (not shown in the figure, not shown in the figure) is provided on the shaft of the pitch fine-tuning motor 26. The fine-tuning gear meshes with the second rack portion.
[0046] In this technical solution, the relative positions of the limiting frame 21 and the adapter plate 25 are adjusted by the spacing fine-tuning motor 26, resulting in higher adjustment accuracy and ensuring the positional accuracy of each limiting frame 21, thereby improving the stacking accuracy of the metal elements. In a specific embodiment, the difference in the position of the upper and lower metal elements on one side after stacking (also known as the single-sided gap of the blank assembly) is within ±1mm. It should be emphasized that in this application, the position of the adapter plate 25 is efficiently coarsely adjusted by the telescopic hydraulic cylinder component 241, which allows the limiting frame 21 to approach the target spacing (target position) more quickly. Then, the position (spacing) of the limiting frame 21 is further precisely adjusted by the spacing fine-tuning motor 26, which obviously improves the efficiency of spacing adjustment while ensuring the accuracy of spacing adjustment.
[0047] It will be readily understood by those skilled in the art that, without conflict, the advantageous technical features of the above-mentioned methods can be freely combined and superimposed.
[0048] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model. The above description is only a preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
