Description

Technical Field

[0001] This utility model relates to the field of material handling technology, and in particular to an auxiliary device for hoisting coarse bar stock. Background Technology

[0002] In the metal processing industry, the hoisting of crude metal bars is a common operation. For the hoisting of such heavy bars, the common method is to directly hoist them with wire ropes or slings. During operation, the rope needs to be passed through the bottom of the bar and then hooked onto the crane hook.

[0003] The existing patent publication number is CN217478176U, and the patent title is "A Special Metal Bar Storage Rack." This utility model includes: a base beam; multiple uprights spaced apart on the top surface of the base beam, with two uprights located at either end of the base beam; multiple lifting plates positioned between two adjacent uprights; and at least two lifting devices evenly distributed below the lifting plates and the base beam. This utility model addresses the technical problems of excessive space requirements for storing special metal bars of multiple grades / batch numbers, long material retrieval times, and strenuous lifting operations for special metal bars.

[0004] Including the aforementioned existing technologies, smooth-surfaced metal bars are highly susceptible to rolling and slipping due to shift in the center of gravity or rope slippage the moment they are lifted off the support surface. This poses a serious safety threat to on-site equipment and operators. Typically, multiple workers are required to manually support the bars or to place wooden blocks or other objects on both sides of the bars for positioning. The lifting process is cumbersome, time-consuming, and labor-intensive. Furthermore, during the lifting and placement process, the bars often experience rigid collisions and friction with the ground or supporting equipment, which may not only scratch the surface of the bars and affect the processing quality but also damage the lifting slings and the workshop floor. Utility Model Content

[0005] The purpose of this invention is to provide an auxiliary device for hoisting coarse bar stock, so as to overcome the above-mentioned shortcomings in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a coarse bar hoisting auxiliary device, comprising multiple interconnected bases, a column fixedly connected to one side of the top of each base, a support frame movably installed on the top of each base, diagonal bars fixedly connected to both sides of each support frame, multiple elastic telescopic bars installed between the support frame and the base, an elastic support member installed inside the column, the elastic support member being located below the diagonal bars, a plug-in guide frame fixedly connected to the elastic support member, and a wedge-shaped slot inclined against the plug-in guide frame being provided on the other side of the top of the base.

[0007] Preferably, the column is hollow inside, and the elastic support includes an auxiliary support frame installed inside the column. Both sides of the column are vertically provided with through slots for the auxiliary support frame to pass through. A pad is fixedly connected to the bottom of the auxiliary support frame, and a buffer spring is fixedly connected between the pad and the base.

[0008] Preferably, the elastic telescopic rod includes a sleeve fixed to the top of the base, a support rod inserted into the sleeve, a top spring installed at the bottom of the support rod inside the sleeve and abutting against the sleeve, and the top of the support rod being fixedly connected to the bottom of the support frame.

[0009] Preferably, one side of the pad has a through groove and a horizontally fixed anti-deviation crossbar, which slides in contact with the column, and the other side of the pad is connected to the plug-in guide frame.

[0010] Preferably, a limiting pad is fixedly connected to the bottom of the two through slots, and a safety gap is reserved between the limiting pad and the anti-deviation crossbar.

[0011] Preferably, anti-collision rubber strips are vertically fixed to both sides of the column.

[0012] This utility model provides an auxiliary device for hoisting coarse bar stock. It has the following beneficial effects:

[0013] This auxiliary device for lifting large quantities of bar stock adapts to the batch lifting and placement of bar stock through flexible connections between multiple devices. The movable support frame, diagonal braces, and elastic support components within the columns work together to form a natural positioning structure when supporting the bar stock, achieving automatic centering using the bar stock's own weight. Multiple elastic telescopic rods and elastic support components between the support frame and the base together constitute a multi-dimensional buffer system, effectively absorbing the impact and vibration generated by the bar stock during lifting. Furthermore, the inclined insertion design of the guide frame and wedge-shaped slot allows the support frame under pressure in one device to press down and insert into the wedge-shaped slot in another device, ensuring the structural rigidity and stability of the entire device under high load conditions.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Reference Figure 1-4A lifting auxiliary device for coarse bar stock includes at least two rows of multiple bases 1 connected side by side. A column 2 is fixedly connected to one side of the top of the base 1. A support frame 3 is movably installed on the top of the base 1. Diagonal bars 4 are fixedly connected to both sides of the support frame 3. Multiple elastic telescopic bars 5 are installed between the support frame 3 and the base 1. An elastic support member 6 is installed inside the column 2 and is located below the diagonal bars 4. When the bar stock is lifted onto this device, the bar stock first falls into the V-shaped area formed by the support frame 3 and the diagonal bars 4 on both sides. Due to the guiding effect of the diagonal bars 4 and the weight of the bar stock itself, the bar stock will naturally roll to the lowest point of the V-shaped area, thereby achieving automatic centering and positioning without the need for precise manual adjustment of the lifting position, improving lifting efficiency and safety. The impact force generated when the bar stock is lowered will act on the support frame 3. The impact force is first transmitted to multiple elastic telescopic rods 5 through the support frame 3. The elastic telescopic rods 5 are compressed, absorbing most of the vertically downward impact energy. At the same time, the lateral swaying or rolling of the bar stock will be transmitted to the elastic support member 6 inside the column 2 through the diagonal rod 4. The elastic support member 6 undergoes elastic deformation, absorbing the horizontal impact and vibration. Thus, the elastic telescopic rods 5 and the elastic support member 6 together form a multi-dimensional buffer system that can cope with impacts in multiple directions, including vertical and horizontal, effectively protecting the bar stock and lifting equipment, and reducing noise. A plug-in guide frame 7 is fixedly connected to the elastic support member 6. A wedge-shaped slot 101 is provided on the other side of the top of the base 1, which is inclined and abuts against the plug-in guide frame 7. When a device presses down its support frame 3 due to the load, it will drive the diagonal rod on it. 4. As the diagonal bar 4 moves downward synchronously, its lower edge presses against the elastic support 6 inside the adjacent device column 2, thereby pushing the insertion guide 7, which is fixedly connected to the elastic support 6, to move downward. Since the insertion guide 7 is inclined, it generates a lateral component force as it moves downward, causing it to insert more tightly into the wedge slot 101 on the adjacent device base 1, and converting it into a lateral locking force between the devices. The greater the load and the deeper the downward pressure, the greater the locking force between the insertion guide 7 and the wedge slot 101, which greatly enhances the structural rigidity and overall stability of the entire connection device assembly under heavy load, preventing the device from tilting or shifting. When the bar is hoisted upward, the elastic telescopic bar 5 and the elastic support 6 can also effectively absorb the impact and vibration generated by the bar during hoisting.

[0022] In a further embodiment of this utility model, the column 2 is hollow inside, and the elastic support 6 includes an auxiliary support frame 601 installed inside the column 2. Vertical through slots 201 are provided on both sides of the column 2 for the auxiliary support frame 601 to pass through. A pad 602 is fixedly connected to the bottom of the auxiliary support frame 601, and a buffer spring 603 is fixedly connected between the pad 602 and the base 1. When the bar is unstable or rolls, its lateral force is transmitted to the top of the auxiliary support frame 601 through the diagonal bar 4. The auxiliary support frame 601 transmits the force downward to the pad 602, thereby compressing the buffer spring 603. The buffer spring 603 undergoes elastic deformation, effectively absorbing and buffering the lateral impact energy. After the impact, the restoring force of the spring in the buffer pushes the entire elastic support 6 to reset, preparing for the next impact. This structure modularizes the support and buffer functions, making the structure simple and reliable, and facilitating the maintenance and replacement of the buffer spring 603. In scenarios where multiple devices are connected, when the support frame 3 of one device is pressed down, the lower edge of the diagonal bar 4 presses against the top of the auxiliary support frame 601 of the adjacent device. This downward pressure will be transmitted more smoothly through the auxiliary support frame 601 and the pad 602 to the buffer spring 603 to compress it.

[0023] In a further embodiment of this utility model, the elastic telescopic rod 5 includes a sleeve 501 fixed to the top of the base 1, a support rod 502 inserted into the sleeve 501, and a top spring 503 abutting against the sleeve 501 installed at the bottom of the support rod 502 inside the sleeve 501. The top of the support rod 502 is fixedly connected to the bottom of the support frame 3. When the bar is hoisted onto the support frame 3, the huge vertical impact force causes the support frame 3 to press down, thereby pushing the support rod 502 to slide downward along the sleeve 501. The support rod 502 compresses the top spring 503 at its bottom. The top spring 503 undergoes significant elastic deformation, generating [something] when the bar is lowered. Most of the kinetic energy generated is converted into elastic potential energy and stored, thus effectively absorbing and buffering the vertical impact. Subsequently, the top spring 503 releases potential energy to try to push the support rod 502 and the support frame 3 back to the initial position to counteract the vibration and make the bar eventually come to a stable stop. Multiple such elastic telescopic rods 5 work together to ensure that the support frame 3 buffers evenly and stably when bearing heavy loads. The elastic telescopic rod 5 is mainly responsible for dealing with vertical loads and impacts. It complements the elastic support 6 in the column 2, which is mainly responsible for dealing with lateral loads and swaying, and together they form a more defined and efficient multi-dimensional buffer system.

[0024] In a further embodiment of this utility model, a horizontal anti-deviation crossbar 604 is horizontally fixedly connected to one side of the pad 602 through the through groove 201. The anti-deviation crossbar 604 slides in contact with the column 2. The other side of the pad 602 is connected to the plug-in guide frame 7. The sliding cooperation between the anti-deviation crossbar 604 and the through groove 201 adds a key guiding and limiting mechanism to the entire elastic support 6. It ensures that when the elastic support 6 is pressed down by the inclined rod 4 or rebounded by the buffer spring 603, it can only move smoothly in a strictly vertical direction. This effectively prevents torsion, tilting, or jamming with the inner wall of the column 2 that may occur due to lateral force. This ensures that the force direction of the buffer spring 603 is always vertical, resulting in better buffering effect, improved service life of the component, and enhanced linkage accuracy and reliability. Due to the anti-deviation effect of the anti-deviation crossbar 604, the movement trajectory of the insertion guide 7, which is fixedly connected to the other side of the pad 602, is also strictly limited. When the support frame 3 presses down and pushes the elastic support 6 through the diagonal bar 4, the insertion guide 7 can move down accurately along the preset inclined path, thereby accurately and reliably inserting into the wedge slot 101 of the adjacent device. This avoids the problem of poor insertion or poor contact caused by the shaking of the elastic support 6, and ensures that the load linkage locking mechanism can be triggered in a timely and efficient manner when multiple devices are connected, which greatly enhances the rigidity and stability of the overall structure under high load conditions.

[0025] In a further embodiment of this utility model, limiting pads 202 are fixedly connected to the bottom of the two through slots 201. A safety gap is reserved between the limiting pads 202 and the anti-deviation crossbar 604. The core function of the limiting pads 202 is to set a mechanical hard limit for the downward movement of the elastic support 6. In conventional hoisting operations, the impact energy of the bar is fully absorbed by the elastic deformation of the elastic telescopic rod 5 and the buffer spring 603. The anti-deviation crossbar 604 moves up and down in the through slots 201, but will not contact the limiting pads 202 at the bottom. In other words, a safety clearance is always present. When an unexpected overload far exceeds the design range, the buffer spring 603 and the elastic telescopic rod 5 may be compressed to their limit. At this time, the anti-deviation crossbar 604 will move down and eventually contact the limiting pad 202. The rigid limiting pad 202 will bear the remaining impact force, which effectively prevents the buffer spring 603 from being crushed and also avoids rigid collisions between the support rod 502 and other components and the bottom of the sleeve 501. This plays a key role in overload protection and improves the overall reliability and service life of the device.

[0026] In a further embodiment of this utility model, anti-collision strips 203 are vertically fixedly connected to both sides of the column 2. During the hoisting or position adjustment of the bar stock, contact or collision with the column 2 is inevitable. The anti-collision strips 203, as a flexible buffer layer, can effectively absorb the impact energy generated by such collisions, preventing the hard metal column 2 from directly impacting the surface of the bar stock, thereby preventing damage to the coating or the bar stock itself due to impact. At the same time, it also protects the surface paint and structure of the column 2 itself, reduces the maintenance requirements of the equipment, extends the service life of the device, and can significantly reduce the noise generated during operation, improving the working environment.
