Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to an auxiliary device for quick assembly and disassembly of disc-lock scaffolding. Background Technology

[0002] Disc-lock scaffolding has been widely used in modern construction due to its modular design and high load-bearing capacity. Its core connection structure achieves rapid locking through evenly distributed disc-shaped node plates on the uprights and wedge-shaped pins at the ends of the horizontal bars.

[0003] However, there are still many inconveniences in the actual assembly and disassembly of disc-lock scaffolding. Traditional disassembly and assembly methods require workers to use hammers to strike the multiple pins distributed in a circle on each upright, so that they are detached from the joint plate or tightly fixed. This repeated hammering method is not only labor-intensive and inefficient, but also easily makes construction workers feel tired, thus restricting the construction progress. At the same time, it is difficult to accurately control the force and angle of manual hammering, which can easily damage the discs, pins and other components of the scaffolding, affecting its reusability and structural safety. Utility Model Content

[0004] The purpose of this utility model is to provide an auxiliary device for quick assembly and disassembly of disc-lock scaffolding, thereby solving the problems existing in the prior art.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows: A quick assembly and disassembly auxiliary device for disc-lock scaffolding includes two symmetrically arranged, hollow, and open-bottom semi-annular plates; a fixed handle assembly hinged to the ends of the two semi-annular plates at its front end; a linkage drive mechanism connected to the two semi-annular plates for driving their opening and closing; a hammer plate disposed at the bottom opening of the semi-annular plates; multiple elastic reset assemblies connected between the top of the inner cavity of the semi-annular plates and the hammer plate; and multiple hammering drive mechanisms disposed within the inner cavity of the semi-annular plates for driving the hammer plate to periodically press down.

[0006] Preferably, the fixed handle assembly includes: a hollow fixed handle and a mounting plate fixedly disposed at the front end of the fixed handle, wherein the ends of the two semi-annular plates are respectively hinged to the mounting plate.

[0007] Preferably, the linkage drive mechanism includes: a movable sleeve slidably sleeved on the outside of the fixed handle, a locking member disposed between the fixed handle and the movable sleeve for fixing the position of the movable sleeve, and two sets of symmetrically arranged bi-links, one end of the bi-links being hinged to the connecting lug outside the movable sleeve and the other end being fixedly connected to the end of the semi-annular plate.

[0008] Preferably, the locking component includes: a mounting base on the outer side wall of the front end of the movable sleeve; a pressing plate rotatably connected to the mounting base via a rotating rod to form a lever structure; a locking rod at the front end of the pressing plate; a locking hole penetrating the side wall of the fixed handle for the locking rod to be inserted; and a pressing spring with its two ends fixed to the bottom of the front end of the pressing plate and the outer surface of the movable sleeve, respectively. The pressing plate is spaced apart from the outer wall of the movable sleeve. Under normal conditions, the pressing spring pushes the locking rod into the locking hole. When the rear end of the pressing plate is pressed, the locking rod tilts up, disengages from the locking hole, and compresses the pressing spring.

[0009] Preferably, the tail of the movable sleeve is provided with an anti-slip rubber sleeve. Preferably, the hammer driving mechanism includes: a micro motor fixedly connected to the inner sidewall of the semi-annular plate, a drive gear connected to the output end of the micro motor, a reduction gear meshing with the drive gear, a rotating shaft fixed coaxially with the reduction gear and rotatably connected at its end to the inner sidewall of the semi-annular plate, and a cam fixedly sleeved on the rotating shaft. The cam rotates to abut against the upper surface of the hammer impact plate and drives it to move downward. The diameter of the reduction gear is larger than the diameter of the drive gear.

[0010] Preferably, the elastic reset assembly includes: a telescopic rod with one end connected to the top of the inner cavity of the semi-annular plate and the other end connected to the upper surface of the hammer plate, and a compression spring with both ends fixed to the top of the inner cavity of the semi-annular plate and the upper surface of the hammer plate, respectively.

[0011] Preferably, the fixed handle has a battery compartment inside and a motor switch on the outer wall of the fixed handle; the positive and negative terminals of the battery compartment are electrically connected to all the micro motors through wires, and the motor switch is connected in series with the wires.

[0012] The beneficial effects of this utility model through the above technical solution are as follows: 1. This utility model controls the ring structure formed by the closure of two symmetrical semi-annular plates through a linkage drive mechanism. Combined with the layout of the hammering plate at its bottom end, and the synergistic effect of the hammering drive mechanism and the elastic reset component, it realizes the synchronous hammering of all pins in the circumference of the same node plate, which greatly improves the disassembly and assembly efficiency, reduces labor intensity, and avoids fatigue caused by long-term operation. The continuous and stable periodic downward movement of the hammering plate ensures that the vertical impact force is uniform and controllable, avoiding the deviation and jamming caused by manual operation. 2. This utility model uses a linkage structure consisting of a sliding sleeve and a two-linkage rod, which allows the operator to drive the semi-circular plate to open and close with a single push and pull of the sliding sleeve. This ensures that the two semi-circular plates fully avoid the uprights when opening, and that the bottom covers all the pin positions when closed. The locking mechanism, through the cooperation of the pressing plate, locking rod, and pressing spring, enables the quick fixing and unlocking of the sliding sleeve, ensuring the stability of the semi-circular plate during operation. Furthermore, the rigid locking method of inserting the locking rod into the locking hole of the fixed handle prevents accidental unlocking caused by hammering vibration, ensuring the safety of continuous operation. The structure is simple and the operation is convenient. 3. This utility model increases the friction between the operator's hand and the device by providing an anti-slip rubber sleeve at the end of the movable sleeve, effectively preventing the device from slipping when the operator's hands are sweaty or the working environment is humid, thus improving the stability and safety of the operator when using the device. 4. This utility model uses the meshing transmission of a small-diameter drive gear and a large-diameter reduction gear to convert the micro motor into high-torque output through high speed, ensuring that the cam generates sufficient hammering force. The rotating cam abuts against the hammering plate, realizing constant stroke impact in the vertical direction, eliminating the oblique force on the pin, and the micro motor drive realizes automated hammering, replacing manual hammering, reducing labor intensity, improving the consistency of hammering frequency, and further improving disassembly and assembly efficiency. 5. This utility model utilizes the guiding function of the telescopic rod and the elastic extension and resetting function of the compression spring to enable the cam to rotate and disengage from the hammer plate. The spring force of the compression spring can then push the hammer plate to quickly reset, thereby achieving the vertical reciprocating motion of the hammer plate. This ensures the continuity, stability, and accuracy of the hammering operation and improves the reliability of the device. Attached Figure Description

Detailed Implementation

[0015] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0016] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0017] In the description of this utility model, it should be noted that if terms such as "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer" appear to indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the utility model product is in use, they are only for the convenience of describing this utility model and simplifying the description, and 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 of this utility model.

[0018] Furthermore, the terms "first," "second," and "third" are used only for distinguishing descriptions and should not be interpreted as indicating or implying relative importance.

[0019] Furthermore, the use of terms such as "horizontal," "vertical," and "suspended" does not imply that the component must be absolutely horizontal or suspended, but rather that it can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0020] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0021] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0022] like Figures 1-7 As shown, a quick assembly and disassembly auxiliary device for disc-lock scaffolding includes two symmetrically arranged, hollow, and open-bottom semi-annular plates 1; a fixed handle 7 assembly 2 hinged to the ends of the two semi-annular plates 1 at its front end; a linkage drive mechanism 3 connected to the two semi-annular plates 1 for driving their opening and closing; a hammering plate 4 disposed at the bottom opening of the semi-annular plate 1; multiple elastic reset assemblies 5 connected between the top of the inner cavity of the semi-annular plate 1 and the hammering plate 4; and multiple hammering drive mechanisms 6 disposed in the inner cavity of the semi-annular plate 1 for driving the hammering plate 4 to periodically press down.

[0023] The fixed handle 7 assembly 2 includes: a hollow fixed handle 7 and a mounting plate 8 fixedly disposed at the front end of the fixed handle 7, wherein the ends of the two semi-annular plates 1 are respectively hinged to the mounting plate 8.

[0024] It should be noted that when the two semi-circular plates 1 are closed, their inner walls enclose a ring structure coaxial with the scaffold uprights, and the bottom surface of the hammer plate 4 covers the top of all the pins on the uprights. In use, the device first opens the two semi-annular plates 1 via the linkage drive mechanism 3, then inserts the openings of the two semi-annular plates 1 into the upright, allowing the device to fit onto the scaffold upright. The linkage drive mechanism 3 then closes the semi-annular plates 1 to form a ring structure, causing the hammering plate 4 to cover the tops of all the pins. Subsequently, the hammering drive mechanism 6 is activated to periodically press down on the hammering plate 4, striking the pins. Simultaneously, the elastic reset component 5 resets the hammering plate 4 after each press, causing it to reciprocate vertically. The operator moves the device along the upright's axial direction, and the hammering plate 4 continuously hammers the pins of the node plate during this movement, causing them to disengage or insert into the node plate pin holes. This significantly improves disassembly and assembly efficiency, reduces labor intensity, and avoids fatigue caused by prolonged operation. The continuous and stable periodic downward movement of the hammering plate 4 ensures that the vertical impact force is uniform and controllable, preventing deviation and jamming caused by manual operation.

[0025] like Figure 1 As shown, the linkage drive mechanism 3 includes: a movable sleeve 9 slidably sleeved on the outside of the fixed handle 7, a locking member 10 disposed between the fixed handle 7 and the movable sleeve 9 for fixing the position of the movable sleeve 9, and two sets of symmetrically arranged bi-links 11, one end of the bi-links 11 being hinged to the connecting ear 12 outside the movable sleeve 9, and the other end being fixedly connected to the end of the semi-annular plate 1.

[0026] In order to increase the friction between the operator's hand and the device, effectively prevent the device from slipping when the operator's hands are sweaty or the working environment is humid, and improve the stability and safety of the operator when using the device, the tail of the movable sleeve 9 is equipped with an anti-slip rubber sleeve. Among them, such as Figure 3 As shown, the locking component 10 includes: a mounting base 13 on the outer side wall of the front end of the movable sleeve 9; a pressing plate 14 rotatably connected to the mounting base 13 via a rotating rod 15 in the middle to form a lever structure; a locking rod 16 at the front end of the pressing plate 14; a locking hole 17 penetrating the side wall of the fixed handle 7 for the locking rod 16 to be inserted; and a pressing spring 18 with its two ends fixed to the bottom of the front end of the pressing plate 14 and the outer surface of the movable sleeve 9, respectively. The pressing plate 14 is spaced apart from the outer wall of the movable sleeve 9. Under normal conditions, the pressing spring 18 pushes the locking rod 16 into the locking hole 17. When the rear end of the pressing plate 14 is pressed, the locking rod 16 tilts up and disengages from the locking hole 17, compressing the pressing spring 18.

[0027] When the linkage drive mechanism 3 controls the opening and closing of the two semi-annular plates 1, the sliding sleeve 9 slides backward, driving the two semi-annular plates 1 to open through the two-link 11. The device is then fitted onto the upright, so that the pin of the node plate is directly below the bottom opening of the semi-annular plate 1. Then, the sliding sleeve 9 slides forward. During the sliding process, the bottom end of the locking rod 16 also slides on the surface of the sliding sleeve 9, compressing the pressing spring 18. When it moves to the closed position, the locking rod 16, under the action of the pressing spring 18, inserts into the locking hole 17 of the fixed handle 7, causing the two semi-annular plates 1 to close and press the hammer plate 4 against the top of the pin, ensuring the stability of the semi-annular plates 1 during operation. The rigid locking method of the locking rod 16 inserting into the locking hole 17 of the fixed handle 7 prevents accidental unlocking caused by hammering vibration, ensuring the safety of continuous operation. When it is necessary to remove the device from the upright and open the two semi-annular plates 1 again, simply press the pressing plate 14 to compress the spring, causing the locking rod 16 to disengage from the locking hole 17 of the fixed handle 7, and then slide the sliding sleeve 9 backward.

[0028] like Figure 6 As shown, the hammer driving mechanism 6 includes: a micro motor 19 fixedly connected to the inner wall of the semi-annular plate 1, a drive gear 20 connected to the output end of the micro motor 19, a reduction gear 21 meshing with the drive gear 20, a rotating shaft 22 fixedly coaxially with the reduction gear 21 and rotatably connected at its end to the inner wall of the semi-annular plate 1, and a cam 23 fixedly sleeved on the rotating shaft 22. The cam 23 rotates and abuts against the upper surface of the hammer plate 4 and drives it to move downward. The diameter of the reduction gear 21 is larger than the diameter of the drive gear 20.

[0029] The fixed handle 7 has a battery compartment inside and a motor switch 26 on its outer wall. The positive and negative terminals of the battery compartment are electrically connected to all the micro motors 19 through wires, and the motor switch 26 is connected in series with the wires.

[0030] like Figure 7 As shown, the elastic reset assembly 5 includes: a telescopic rod 24 with one end connected to the top of the inner cavity of the semi-annular plate 1 and the other end connected to the upper surface of the hammer plate 4, and a compression spring 25 with both ends fixed to the top of the inner cavity of the semi-annular plate 1 and the upper surface of the hammer plate 4, respectively.

[0031] It should be noted that: the drive gear 20 and the reduction gear 21 adopt a small drive and large driven diameter ratio design, and their transmission ratio is preferably 1:3-1:5; the micro motor 19, the battery compartment and the motor switch 26 are all existing technologies, the motor switch 26 can be a self-resetting button switch, and the battery compartment contains rechargeable batteries first; When the motor switch 26 is turned on, the battery compartment supplies power to all the micro motors 19, and the hammer drive mechanism 6 is activated. The micro motors 19 drive the small-diameter drive gear 20 to rotate, which in turn drives the large-diameter reduction gear 21 to reduce speed and increase torque. The reduction gear 21 drives the cam 23 to rotate through the rotating shaft 22. The protrusion of the cam 23 abuts against the upper surface of the hammer plate 4, driving the hammer plate 4 to move downward, so that the hammer plate 4 impacts the top or bottom of the pin. When the cam 23 rotates back, the compression spring 25 pulls the hammer plate 4 to reset through the telescopic rod 24, completing one hammering cycle. With the continuous rotation of the cam 23, the periodic downward action of the hammer plate 4 is completed, thereby completing the continuous and stable hammering of the pin and realizing the rapid assembly and disassembly of the disc-lock scaffold.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described with reference to preferred embodiments, those skilled in the art should understand that various changes in form and detail can be made without departing from the spirit and scope of this utility model as defined in the appended claims.
