Description

Technical Field

[0001] This invention relates to the field of column base protection structure technology, specifically to a column base impact warning protection device. Background Technology

[0002] As a key node connecting the upper load-bearing components and the foundation in a building structure, the structural integrity and safety of column bases are directly related to the stability of the entire building. Column bases in the work area are constantly exposed to the risk of accidental collisions. Accidental impacts such as vehicles reversing and mechanical contact can cause structural damage to column bases. These impacts are mainly caused by accidental collisions due to blind spots, and the initial velocity of such impacts in the work area is generally not high. If timely feedback and warnings can be provided, damage can be effectively prevented.

[0003] Currently, the main protective measures for column bases are physical isolation. Common practices include pouring a concrete protective layer around the column base or setting up a simple protective cover. Some protective devices achieve visual alerts by spraying reflective warning tape or fluorescent powder on the formwork surface. However, existing technologies have significant shortcomings: they cannot provide protection and early warning for accidental touches caused by blind spots, and it is difficult to transmit impact event information to maintenance personnel and those involved in the impact in the first instance, which can easily exacerbate the severity of the impact.

[0004] To avoid the above problems, we propose a column base protection device that combines impact protection and active warning functions, which can trigger an early warning while withstanding external impacts, and promptly remind relevant personnel. Therefore, we propose a column base impact warning protection device. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings mentioned in the background art and provide a column base impact warning protection device.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A column base impact warning protection device includes: Multiple side formwork panels are installed around the column base, and concrete is poured and filled between the inner cavity of the side formwork panels and the column base. The impact protection unit includes a limiting sleeve fitted around the outside of the multiple side templates, and an external convex cover that is horizontally slidable along the circumference of the limiting sleeve and corresponds one-to-one with the side templates. An impact feedback component is installed on the outer wall of the side template. The impact feedback component includes a liquid tank with reciprocating force units installed on both sides, and a top guide plate set at the top of the liquid tank for rising and falling with the liquid level. When the convex cover is subjected to external impact, it is used to push the liquid level in the liquid tank to rise by squeezing the reciprocating force unit, and to push the top guide plate upward. The top plate is installed above the side template, and the bottom plate surface is provided with a groove corresponding to the position of the top guide plate. Two disconnected switch plates are installed in the groove, and the two switch plates are electrically connected to a buzzer alarm. When the top guide plate is pushed upwards to fit against the two switch plates, a closed alarm circuit is formed, and the buzzer alarm is triggered for automatic early warning.

[0007] Preferably, the reciprocating force unit includes a vertical liquid pipe and a horizontal telescopic sleeve arranged in an inverted L-shape with continuous conduction and closed at both ends. A spring is installed at the bottom of the vertical liquid pipe, and a piston for supporting multiple rolling balls is connected to the top of the spring. The ball is rolled along the vertical liquid pipe and the horizontal telescopic sleeve.

[0008] Preferably, the outer end of the horizontal telescopic sleeve is fixedly installed on the inner wall of the outer convex cover to ensure that the horizontal telescopic sleeve and the outer convex cover move synchronously. When the convex cover is subjected to external impact, it simultaneously compresses the horizontal telescopic sleeve and forces the rolling ball to continuously press into the vertical liquid pipe, squeezing the liquid level in the liquid tank and the vertical liquid pipe to rise, thereby driving the top guide plate to rise upward.

[0009] Preferably, the liquid tank is equipped with a float plate that floats on the liquid surface inside the liquid level feedback chamber, and the top guide plate is vertically inserted above the liquid tank via an insulating guide rod, with the bottom end of the insulating guide rod being fixedly connected to the float plate.

[0010] Preferably, a flow hole is provided at the corresponding surface where the vertical liquid pipe is fixedly connected to the liquid tank, and both the liquid level feedback chamber and the vertical liquid pipe are filled with liquid.

[0011] Preferably, the outer wall of the side template is provided with a vertical groove for vertically inserting the impact feedback component.

[0012] Preferably, the limiting sleeve is provided with a plurality of insertion windows along the circumference for horizontally sliding and inserting the outer convex cover; The inner end of the convex cover is provided with a limiting edge plate, which is used to abut against the inner wall of the limiting sleeve to limit the outward sliding distance.

[0013] Preferably, a protective plate coaxially arranged is installed on the outside of the convex cover.

[0014] Preferably, the buzzer alarm is fixedly installed on the top surface of the top plate.

[0015] Preferably, the limiting sleeve includes symmetrically arranged semi-cylindrical structures to facilitate the assembly of the impact feedback component.

[0016] Compared with the prior art, the beneficial effects of the present invention are: 1. This column base impact warning protection device can achieve the coordinated linkage of physical impact protection and instantaneous automatic early warning. It can actively issue a warning when a collision occurs, effectively preventing continuous damage to the column base, and has both protective and early warning functions. 2. This application adopts a pure mechanical hydraulic triggering structure, which does not rely on electronic sensors and external continuous power supply. It has strong anti-interference ability and can maintain high reliability even in harsh outdoor environments. After the impact disappears, it automatically resets through the spring and can be used repeatedly for a long time. 3. This application allows for flexible setting of different impact warning thresholds by adjusting the number of rolling balls, spring stiffness, and liquid tank volume, making it suitable for column base scenarios with different protection levels; at the same time, the side formwork and concrete pouring form a stable foundation protection, with a compact overall structure and convenient installation and maintenance.

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Please see Figures 1-12 The present invention will describe the above technical solution in detail through the following embodiments: This embodiment provides a column base impact warning type protective device, such as Figure 1 , Figure 2 and Figure 10 As shown, the side templates 2 are configured as four enclosures installed around the column base 1. In this embodiment, the column base 1 is a square column base, and the templates are respectively attached to the four sides of the column base 1. An enclosure structure is formed between adjacent side templates 2. A gap is left between the inner cavity formed by the enclosure of the side templates 2 and the outer wall of the column base 1. Concrete is poured and filled into this gap. After the concrete cures, it forms a protective layer that wraps around the column base 1, which not only enhances the structural bearing capacity of the column base 1, but also provides basic physical protection for the column base 1. After the concrete is poured and formed, the side templates 2 are retained outside the column base 1 as part of the permanent protective structure and do not need to be removed. In this embodiment, the side templates 2 are made of steel plates to ensure that they have sufficient structural strength.

[0021] like Figure 5 and Figure 6 As shown, a vertical groove 21 is provided on the outer side wall of the side template 2. The vertical groove 21 extends vertically along the outer side wall of the side template 2 for the subsequent vertical insertion of the impact feedback component 3, and plays a role in positioning and limiting the impact feedback component 3 to ensure the reliability of the force transmission process.

[0022] like Figure 2 , Figure 3 and Figure 4As shown, in this embodiment, the impact protection part is disposed on the outside of the side template 2, specifically including a limiting sleeve 4 and four outwardly protruding covers 5. The limiting sleeve 4 is fitted onto the outside of the four side templates 2; as Figure 11 As shown, the limiting sleeve 4 is provided with an insertion window 401 along the circumference. The insertion window 401 is a rectangular through hole that penetrates the wall of the limiting sleeve 4. The number of the insertion windows 401 corresponds one-to-one with the number of the side templates 2. In this embodiment, there are four insertion windows 401. The convex cover 5 is horizontally slidably inserted into the corresponding insertion window 401 along the circumference of the limiting sleeve 4, and the convex cover 5 is provided one-to-one with the side template 2. Specifically, the convex cover 5 is a cover structure with its opening facing the inside of the limiting sleeve 4. Its outer end face protrudes from the outer wall surface of the limiting sleeve 4. A limiting edge plate 51 is provided at the inner edge of the convex cover 5. When the convex cover 5 slides outward to the limit position in the direction away from the side template 2, the limiting edge plate 51 abuts against the inner wall surface of the limiting sleeve 4, thereby limiting the maximum displacement of the convex cover 5 sliding outward and preventing the convex cover 5 from completely coming out of the insertion window 401.

[0023] In this embodiment, a protective plate 6 is coaxially mounted on the outside of the convex cover 5. The protective plate 6 is fixedly mounted on the outer end face of the convex cover 5 by bolts. The protective plate 6 has an arc-shaped plate structure, and its area is larger than the area of ​​the outer end face of the convex cover 5. This is used to expand the impact receiving area and improve the sensitivity to external collisions. In this embodiment, a rubber buffer pad layer is also sandwiched between the outer end face of the convex cover 5 and the protective plate 6 to absorb the initial kinetic energy of external impacts, play a buffering and vibration reduction role, and extend the service life of the device.

[0024] like Figure 11 As shown, in this embodiment, the limiting sleeve 4 adopts two symmetrically arranged semi-cylinder structures for easy installation. The two semi-cylinder structures can be welded together after installation; or in other embodiments, lug mounting bolts can be detachably connected, which facilitates on-site assembly and disassembly outside the side template 2, and also facilitates subsequent inspection and replacement of the internal impact feedback component 3.

[0025] like Figures 5-9 As shown, in this embodiment, the impact feedback component 3 is vertically inserted into the vertical groove 21 on the outer side wall of the side template 2. The impact feedback component 3 includes a liquid tank 31, a reciprocating force unit 32, and a top guide plate 33. Specifically, the liquid tank 31 is a hollow box structure, and a liquid level feedback cavity 3101 is formed inside it. The liquid level feedback cavity 3101 is filled with liquid, which is water, to provide liquid level changes. Two reciprocating force units 32 are provided and are respectively connected and installed on the left and right sides of the liquid tank 31, as shown. Figure 8As shown, the reciprocating force unit 32 includes a vertical liquid pipe 321 and a horizontal telescopic sleeve 322 arranged in an inverted L-shape. Both the vertical liquid pipe 321 and the horizontal telescopic sleeve 322 are hollow tubes with closed ends. Their internal cavities are interconnected to form a continuous liquid and ball channel. The vertical liquid pipe 321 is vertically arranged with its bottom end being a closed end. The horizontal telescopic sleeve 322 is horizontally arranged. The inner end of the horizontal telescopic sleeve 322 is fixedly connected to the upper side wall of the vertical liquid pipe 321 and their internal cavities are interconnected. The outer end of the horizontal telescopic sleeve 322 is a closed end.

[0026] It should be noted that, as Figure 8 As shown, a spring 333 is installed at the bottom of the vertical liquid pipe 321. The bottom end of the spring 333 is fixed to the bottom wall of the inner cavity of the vertical liquid pipe 321, and the top end is connected to a piston 334. The piston 334 slides in cooperation with the inner wall of the vertical liquid pipe 321 and can slide up and down vertically inside the vertical liquid pipe 321. At the same time, multiple rolling balls 335 are supported above the piston 334. In this embodiment, the rolling balls 335 are steel balls, and their diameter is adapted to the inner diameter of the vertical liquid pipe 321 and the horizontal telescopic sleeve 322, so that the rolling balls 335 can roll smoothly inside the pipe of the vertical liquid pipe 321 and the horizontal telescopic sleeve 322. At the same time, a small gap is maintained between the rolling balls 335 and the pipe wall to prevent the rolling balls 335 from deviating and getting stuck in the pipe. The number of rolling balls 335 is preferably 4 to 6 to ensure that the pressed volume is sufficient and thus provides sufficient buoyancy height.

[0027] In this embodiment, the horizontal telescopic sleeve 322 comprises multiple interlocking pipe sections. To achieve the displacement distance of telescopic folding, the multiple pipe sections slide and seal together, allowing the horizontal telescopic sleeve 322 to telescopically extend and retract along its axial direction. The outer end of the horizontal telescopic sleeve 322 is fixedly installed on the inner wall of the outer convex cover 5 by welding, ensuring that the horizontal telescopic sleeve 322 and the outer convex cover 5 maintain synchronicity during horizontal movement. That is, when the outer convex cover 5 is impacted by an external force and moves towards the side template 2, the outer convex cover 5 synchronously compresses the horizontal telescopic sleeve 322, shortening its length. This process compresses the ball bearing 335 into the liquid, compresses the spring 333, and causes the liquid level to rise. Once the impact is detected and released, the ball bearing 335, the horizontal telescopic sleeve 322, and the outer convex cover 5 will be reset under the elastic restoring action of the spring 333, making it reusable.

[0028] like Figures 7-9As shown, in this embodiment, a flow hole 3201 is provided on the corresponding surface of the vertical liquid pipe 321 and the liquid tank 31 that are fixedly connected. Specifically, the side wall of the vertical liquid pipe 321 is attached to and sealed to the side wall of the liquid tank 31 to maintain effective liquid storage. The flow hole 3201 is opened at the contact surface of the two, so that the internal cavity of the vertical liquid pipe 321 and the liquid level feedback cavity 3101 of the liquid tank 31 are interconnected through the flow hole 3201. Both the liquid level feedback cavity 3101 and the vertical liquid pipe 321 are filled with liquid water, and the connection is maintained to achieve the same liquid level height between the two.

[0029] In this embodiment, to provide feedback on quantitative changes in liquid level, a float plate 35 is inserted into the liquid level feedback chamber 3101 of the liquid tank 31. The float plate 35 is a hollow plastic sealing plate that floats on the liquid surface in the liquid level feedback chamber 3101 and can float freely up and down with the rise and fall of the liquid level. A top guide plate 33 is disposed above the top of the liquid tank 31, and an insulating guide rod 34 is fixedly connected to the bottom of the top guide plate 33. The insulating guide rod 34 is vertically arranged, and its lower end passes through a guide hole opened on the top wall of the liquid tank 31 and extends into the liquid level feedback chamber 3101. The bottom end of the insulating guide rod 34 is fixedly connected to the upper surface of the float plate 35. In this embodiment, the insulating guide rod 34 is made of plastic and has good electrical insulation properties. When the liquid level in the liquid level feedback chamber 3101 rises, the float plate 35 floats upward with the rise of the liquid level, and pushes the top guide plate 33 upward synchronously through the insulating guide rod 34.

[0030] like Figure 1 , Figure 2 and Figure 12 The top plate 7 is horizontally installed above the side template 2. The top plate 7 is also set as two symmetrical flat plate structures for easy assembly. Its lower surface is fixedly connected to the top surface of each side template 2 by bolts to complete the top sealing and positioning. It should be noted that in this embodiment, a groove 701 is provided on the bottom plate surface of the top plate 7. The position of the groove 701 is directly opposite to the position of the top guide plate 33 and corresponds one-to-one.

[0031] Specifically, in this embodiment, the groove 701 is a rectangular recess formed on the bottom surface of the top plate 7. Two switch plates 9 are fixedly installed in the groove 701. Both switch plates 9 are conductive metal sheets made of copper. They are spaced apart in the groove 701 and do not contact each other, forming a normally open state. The two switch plates 9 are electrically connected to the two terminals of the buzzer alarm 8 through wires. The buzzer alarm 8 is fixedly installed on the top surface of the top plate 7 and is also connected to an external power supply, forming an alarm circuit. Under normal conditions, due to the two switch plates 9... When the circuit is in the open state, the alarm circuit is in the open state, and the buzzer alarm 8 does not work. When the top guide plate 33 is pushed upward into the embedded groove 701 and simultaneously abuts the two switch plates 9, since the top guide plate 33 itself is a conductive material, the top guide plate 33 electrically connects the two open switch plates 9, so that a closed connection is formed between the two switch plates 9, thereby closing the entire alarm circuit. The buzzer alarm 8 is powered on and automatically triggers the warning, emitting a continuous buzzing warning sound to remind the on-site personnel that the column foot 1 has been subjected to external impact and that braking and response measures need to be taken in time.

[0032] The specific working process of this embodiment is as follows: During the installation stage, multiple side templates 2 are installed around the column base 1, and concrete is poured in the gap between the side templates 2 and the column base 1. After the concrete solidifies, a protective layer for the column base is formed. Then, the outer end of the horizontal telescopic sleeve 322 is fixedly connected to the inner wall of the outer convex cover 5. Next, the impact feedback component 3 is vertically inserted into place along the vertical groove 21 on the outer side wall of the side template 2. At the same time, the outer convex cover 5 is horizontally inserted from the outside of the insertion window 401 of the limiting sleeve 4, so that the inner end of the outer convex cover 5 extends into the inside of the limiting sleeve 4, and the limiting edge plate 51 is located on the inner side of the limiting sleeve 4. The two semi-cylindrical structures of the limiting sleeve 4 are fixed. Finally, the top plate 7 is installed above the side template 2 to complete the overall assembly.

[0033] The specific working principle of this embodiment is as follows: When the column base 1 is accidentally hit by an external object, such as a reversing vehicle or mobile machinery, in the working area, the impact force first acts on the outer surface of the guard plate 6. The guard plate 6 transmits the impact force to the outer convex cover 5 fixedly connected to it, pushing the outer convex cover 5 to slide horizontally along the insertion window 401 into the limiting sleeve 4. When the outer convex cover 5 moves inward, it simultaneously compresses the horizontal telescopic sleeve 322 fixed on its inner wall, shortening the length of the horizontal telescopic sleeve 322. During the shortening process of the horizontal telescopic sleeve 322, the ball 335 inside it is squeezed and pushed by the inner wall of the sleeve, rolling along the pipeline towards the vertical liquid pipe 321. The ball 335 continuously enters the vertical liquid pipe 321. The ball 335 entering the vertical liquid pipe 321 squeezes the liquid in the vertical liquid pipe 321 downward, so that the liquid is squeezed and then pressed into the liquid level feedback chamber 3101 of the liquid tank 31 through the flow hole 3201, causing the liquid level height in the liquid level feedback chamber 3101 to rise continuously.

[0034] The float 35 rises synchronously with the liquid level in the liquid level feedback chamber 3101, pushing the top guide plate 33 upwards via the insulating guide rod 34. When the external impact force reaches the preset trigger threshold, the top guide plate 33 rises into the groove 701 embedded in the bottom surface of the top plate 7, and simultaneously contacts and adheres to the two switch plates 9 in the groove 701. Since the top guide plate 33 is made of conductive material, the two disconnected switch plates 9 form an electrical connection through the top guide plate 33, the alarm circuit is closed, the buzzer alarm 8 is energized and emits a continuous buzzer alarm sound, sending a warning signal to the on-site operators, indicating that the column foot 1 is being impacted, so that they can take timely avoidance or stop the operation. Operational measures are taken to prevent further damage to column base 1. After the external impact force disappears, under the elastic restoring force of spring 333 within vertical liquid pipe 321, piston 334 pushes ball 335 upwards, causing it to roll and reset in the opposite direction along vertical liquid pipe 321 and horizontal telescopic sleeve 322. Horizontal telescopic sleeve 322 then extends and pushes the outer convex cover 5 outwards to reset. Liquid flows back into vertical liquid pipe 321 through flow hole 3201, causing the liquid level in level feedback chamber 3101 to drop. Float 35 falls back, driving top guide plate 33 downwards via insulating guide rod 34. Top guide plate 33 disengages from the two switch plates 9, disconnecting the alarm circuit and stopping the buzzer alarm 8. The device then automatically returns to its initial ready-to-trigger state and can be reused.

[0035] It should be noted that if the embodiments of the present invention involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indicators will also change accordingly.

[0036] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within the present invention.
