Description

Technical Field

[0001] This utility model relates to the field of glass production and manufacturing technology, and in particular to an auxiliary device for disassembling and assembling a machine rod. Background Technology

[0002] In the glass manufacturing industry, the edge-drawing machine is a key piece of glass forming equipment used to adjust the width and thickness of the formed glass. Currently, most edge-drawing machines use a cantilever structure for their operating rods. Because this cantilever structure operates in a high-temperature environment for extended periods, the average lifespan of the operating rod is only about 12 months. After this lifespan expires, the operating rod needs to be repaired or replaced periodically to ensure the normal operation of glass production.

[0003] However, due to the large weight and length of the machine rod, it is difficult for employees to disassemble and assemble it, resulting in a long disassembly and assembly process, which affects the maintenance efficiency of the equipment and consequently the production efficiency and quality of the entire glass production line. Utility Model Content

[0004] The main purpose of this utility model is to propose an auxiliary device for disassembling and assembling the machine rod, which aims to solve the problem of inconvenience in disassembling and assembling the machine rod of existing edge-pulling machines.

[0005] To achieve the above objectives, the present invention proposes a mast disassembly and assembly auxiliary device, which includes:

[0006] frame;

[0007] A lifting mechanism, mounted on the frame, includes a driving component, which includes a drive shaft movably disposed relative to the frame; and

[0008] A support mechanism is connected to the drive shaft. The support mechanism has a limiting groove, the groove wall of which is used to fit and support the machine rod. The drive shaft moves relative to the frame, driving the support mechanism to move, so as to adjust the height of the limiting groove.

[0009] In one embodiment of the present invention, the support mechanism includes a support base and a cover plate. The support base is connected to the drive shaft. The limiting groove is formed on the side of the support base opposite to the drive shaft. The cover plate is detachably sealed to the opening of the limiting groove.

[0010] In one embodiment of the present invention, the support mechanism further includes a locking member, which includes a connecting part and a fixing part. One end of the connecting part is movably connected to the cover plate, and the other end is connected to the fixing part. The fixing part is moved to press and fix the machine rod under the drive of the connecting part.

[0011] In one embodiment of this utility model, the fixing part is rotatably connected to the connecting part, and the fixing part rotates relative to the connecting part to adjust the orientation of the fixing part.

[0012] In one embodiment of this utility model, the side of the fixing part facing the machine rod is an arc-shaped surface, and the arc-shaped surface is adapted to the machine rod.

[0013] In one embodiment of this utility model, the limiting groove has at least a circular arc surface on its bottom wall, which fits against the outer peripheral surface of the machine rod.

[0014] In one embodiment of this utility model, the machine rod disassembly and assembly auxiliary device further includes a position detection component, which is installed on the support mechanism and is communicatively connected to the drive component. The position detection component is used to control the drive shaft to stop moving when it detects that the machine rod is in contact with the bottom wall of the limiting groove.

[0015] In one embodiment of this utility model, the position detection element is a contact position sensor and is movably installed on the support mechanism.

[0016] In one embodiment of this utility model, the drive shaft is a lead screw, and the drive component further includes a motor. The motor is drivenly connected to the lead screw, the lead screw is mounted on the frame, and the lead screw is drivenly connected to the support mechanism, and under the drive of the motor, it drives the support mechanism to move.

[0017] And / or, the drive shaft is a lead screw, the drive component further includes a rocker arm, the rocker arm is drivenly connected to the lead screw, the lead screw is mounted on the frame, the lead screw is drivenly connected to the support mechanism, rotating the rocker arm drives the lead screw to drive the support mechanism to move.

[0018] In one embodiment of this utility model, both the lifting mechanism and the supporting mechanism are provided in two sets. Each lifting mechanism is driven to connect with one supporting mechanism. The two supporting mechanisms are arranged axially spaced along the limiting groove, and the machine rod is simultaneously supported in the two limiting grooves.

[0019] The auxiliary device for disassembling and assembling a machine rod proposed in this utility model includes a frame, a lifting mechanism, and a support mechanism. The lifting mechanism is mounted on the frame and includes a driving component with a driving shaft, which is movably mounted relative to the frame. The support mechanism is connected to the driving shaft and has a limiting groove. The groove wall is used to fit and support the machine rod. Movement of the driving shaft relative to the frame moves the support mechanism to adjust the height of the limiting groove. When the machine rod needs repair or replacement, the driving component drives the driving shaft to move the support mechanism toward the machine rod until the machine rod fits against the groove wall. At this point, the machine rod is supported in the limiting groove. Moving the frame allows the machine rod to be removed from the edge-pulling machine, thus solving the problem of difficult machine rod disassembly and assembly, and improving production efficiency and quality.

[0029] This utility model proposes an auxiliary device for disassembling and assembling a machine rod.

[0030] Combination Figure 1 As shown, in one embodiment of this utility model, the auxiliary device for disassembling and assembling the mast includes:

[0031] Rack 10;

[0032] Lifting mechanism 20, mounted on frame 10, includes a drive component, which includes a drive shaft 21 movably disposed relative to frame 10; and

[0033] The support mechanism 30 is connected to the drive shaft 21. The support mechanism 30 has a limiting groove 311. The groove wall of the limiting groove 311 is used to fit and support the machine rod 50. The drive shaft 21 moves relative to the frame 10, which drives the support mechanism 30 to move, so as to adjust the height of the limiting groove 311.

[0034] In this embodiment, the frame 10 can be a welded, detachable, or integrally formed frame structure used to install the lifting mechanism 20 and the support mechanism 30. Universal casters 11 with locking function are installed at the four corners of the bottom of the frame 10, allowing the entire device to move flexibly within the glass production workshop. During operation, the locking wheels can achieve stable positioning, preventing slippage during lifting or transport.

[0035] The lifting mechanism 20 is mounted on the frame 10 via welding, detachable connection, or other methods to provide vertical lifting power. The lifting mechanism 20 includes a drive component, which can be powered by a motor 23, a pneumatic cylinder, or a hydraulic cylinder. The drive component is fixedly connected to a mounting plate on the surface of the frame 10 via welding, snap-fit, or threaded connection to ensure that it does not loosen or shift during operation. The drive component has a drive shaft 21 along the vertical direction, with its axis perpendicular to the bottom surface of the frame 10, enabling it to perform linear reciprocating motion relative to the frame 10 under the drive of compressed air or electricity.

[0036] The support mechanism 30 is fixedly connected to the top end of the drive shaft 21 and moves up and down together with the drive shaft 21. The main body of the support mechanism 30 forms an upward-opening limiting groove 311. The cross-sectional shape of the limiting groove 311 is arc-shaped, trapezoidal, or V-shaped, used to accommodate the machine rod 50. Furthermore, the surface of the limiting groove 311 can be treated with anti-slip and cushioning measures, such as by using a rubber or polyurethane cushioning pad, to increase the friction with the surface of the machine rod 50 while preventing scratches. The width of the limiting groove 311 is slightly larger than the diameter of the machine rod 50, and the depth is sufficient to accommodate the lower half of the machine rod 50, ensuring that the machine rod 50 will not easily slip during lifting. When the machine rod disassembly and assembly auxiliary device moves directly under the machine rod 50, the drive unit is activated, the drive shaft 21 extends, and the support mechanism 30 rises until the groove wall of the limiting groove 311 completely contacts and stably supports the body of the machine rod 50, thereby effectively supporting the machine rod 50.

[0037] Specifically, when the installation height of the mast 50 needs to be adjusted, the drive component outputs power to cause axial displacement of the drive shaft 21, and the linkage support mechanism 30 rises and falls synchronously. The groove wall of the limiting groove 311 forms surface contact with the surface of the mast 50, and the limiting groove 311 continuously maintains radial constraint on the mast 50 during the rising and falling process. Through the above technical solution, this application realizes automated height adjustment during the assembly and disassembly of the mast 50, solving the problems of time-consuming, labor-intensive, and inefficient traditional manual assembly and disassembly.

[0038] Combination Figure 1 As shown, in one embodiment of the present invention, the support mechanism 30 includes a support base 31 and a cover plate 32. The support base 31 is connected to the drive shaft 21. A limiting groove 311 is formed on the side of the support base 31 away from the drive shaft 21. The cover plate 32 is detachably sealed to the opening of the limiting groove 311.

[0039] In this embodiment, one end of the support base 31 can be detachably connected to the top end of the drive shaft 21 via threads, flanges, or pins, or can be fixedly connected by welding. On the side of the support base 31 away from the drive shaft 21, an upward-opening limiting groove 311 is formed. The limiting groove 311 extends horizontally through both sides of the support base 31, facilitating the insertion and confinement of the rod 50 within the limiting groove 311.

[0040] The cover plate 32 is positioned above the limiting groove 311 to seal the groove opening, further enhancing the constraint on the machine rod 50. This prevents the machine rod 50 from dislodging from the limiting groove 311 due to vibration or tilting during transport, thus improving operational safety. After covering the groove opening, the cover plate 32 is detachably fixed to the support base 31. The detachable connection method can be a threaded connection, a snap-fit ​​structure, or a pin connection. When it is necessary to load or unload the machine rod 50, simply loosen or open the cover plate 32, place the machine rod 50 into the limiting groove 311, and then re-lock or fasten the cover plate 32, improving the ease of operation.

[0041] Combination Figure 1 As shown, in one embodiment of the present invention, the support mechanism 30 further includes a locking member 33, which includes a connecting part 331 and a fixing part 332. One end of the connecting part 331 is movably connected to the cover plate 32, and the other end is connected to the fixing part 332. The fixing part 332 moves to press against the fixing rod 50 under the drive of the connecting part 331.

[0042] In this embodiment, the connecting part 331 is movably connected to the cover plate 32, and the contact distance between the fixing part 332 and the machine rod 50 is changed by linear displacement. The fixing part 332 is the component that directly contacts the machine rod 50. Its contact surface with the machine rod 50 can be arc-shaped, V-shaped, or serrated, and its function is to clamp and fix the machine rod 50. The connecting part 331 and the fixing part 332 can be connected by means of threaded connection, pin hinge, welding fixation, snap connection, etc. The connecting part 331 and the cover plate 32 are threadedly connected. When the connecting part 331 has an external thread on its outer periphery, the surface of the cover plate 32 has a threaded hole. The connecting part 331 passes through the threaded hole and is threadedly connected to the cover plate 32. By rotating and moving the connecting part 331, the extension length of the fixing part 332 can be adjusted, thereby realizing the continuous adjustment of the position of the fixing part 332. Alternatively, multiple insertion holes can be provided on the connecting part 331, and insertion blocks can be provided on the cover plate 32. By adjusting the insertion blocks to be inserted into the insertion holes at different positions, the connecting part 331 and the cover plate 32 can be movably connected.

[0043] Specifically, after the lever 50 is placed in the limiting groove 311 of the support base 31, the cover plate 32 is first placed over the groove opening and initially fixed. Then, the movable connecting part 331 moves the fixing part 332 downward, gradually pressing the lever 50. As the fixing part 332 is pressed down, the lever 50 is firmly clamped between the bottom of the limiting groove 311 and the fixing part 332, forming a two-way constraint, which significantly improves the overall clamping stability and safety. The movable connection between the connecting part 331 and the cover plate 32 allows the pressing stroke of the fixing part 332 to be adjusted to accommodate levers 50 of different diameters, enhancing the versatility of the device.

[0044] Combination Figure 1 As shown, in one embodiment of the present invention, the fixing part 332 is rotatably connected to the connecting part 331, and the fixing part 332 rotates relative to the connecting part 331 to adjust the orientation of the fixing part 332.

[0045] In this embodiment, the fixing part 332 and the connecting part 331 are rotatably connected by a hinge structure or a rotating shaft structure, so that the fixing part 332 can rotate around the axis of the connecting part 331, so that the angle of the fixing part 332 can be adjusted by rotation during the clamping process, so that the fixing part 332 and the machine rod 50 form a stable surface contact.

[0046] Specifically, when the mounting position of the lever 50 is tilted or its surface has an irregular shape, the fixing part 332 can rotate around the connecting part 331. The operator rotates the fixing part 332 according to the actual mounting angle of the lever 50, so that its contact surface forms a parallel contact with the outer surface of the lever 50. When pressure is applied by the locking member 33, the fixing part 332 adjusts the contact angle by rotation, allowing its contact surface to better fit the surface of the lever 50. When it is necessary to replace the lever 50 with a different diameter, the fixing part 332, after rotating to the new contact angle, can still maintain a surface contact mode between its contact surface and the lever 50. The rotatable characteristic of the fixing part 332 allows it to adapt to different mounting angles and lever 50 diameters, thereby increasing the contact area between the fixing part 332 and the surface of the lever 50 and avoiding localized stress concentration caused by angular deviations.

[0047] Combination Figure 1 As shown, in one embodiment of this utility model, the side of the fixing part 332 facing the machine rod 50 is an arc-shaped surface, which is adapted to the machine rod 50.

[0048] In this embodiment, the fixing part 332 contacts the outer surface of the rod 50 through an arc-shaped surface. When the locking member 33 applies pressure, the clamping force is evenly distributed along the circumference of the rod 50 on the arc-shaped surface, avoiding local point contact that could cause indentations on the surface of the rod 50. Since the curvature of the arc-shaped surface matches the outer diameter of the rod 50, even if the relative position of the fixing part 332 and the rod 50 changes during the height adjustment process of the lifting mechanism 20, the contact surface can still remain in contact, thereby preventing the rod 50 from sliding due to misalignment of the contact surface. Compared to a planar structure that only forms line contact or local point contact with the cylindrical rod 50, resulting in uneven distribution of clamping force and easy slippage, this solution uses an arc-shaped surface design to uniformize the pressure on the contact surface between the fixing part 332 and the rod 50, significantly improving the stability of the fixation under the same locking force.

[0049] Combination Figure 1 As shown, in one embodiment of this utility model, the limiting groove 311 has at least a circular arc surface on its bottom wall, and it fits against the outer peripheral surface of the rod 50.

[0050] In this embodiment, the fact that the bottom wall surface of the limiting groove 311 is at least an arc surface means that the bottom of the groove in the support mechanism 30 used to accommodate the rod 50 has an arc-shaped structure that matches the outer contour of the rod 50. This arc surface forms a continuous surface contact with the outer peripheral surface of the rod 50, so that the gravity of the rod 50 is evenly distributed on the bottom wall surface.

[0051] The radius of curvature of the arc surface is matched with the outer diameter of the rod 50. This solution achieves surface contact through the bottom wall of the arc surface, which not only increases the effective support area, but also improves the problem of horizontal displacement of the rod 50 in the limiting groove 311 through curvature matching, thus improving the support stability.

[0052] Combination Figure 1 As shown, in one embodiment of this utility model, the auxiliary device for disassembling and assembling the mast also includes a position detection component 40. The position detection component 40 is installed on the support mechanism 30 and is communicatively connected to the drive component. It is used to control the drive shaft 21 to stop moving when it detects that the mast 50 is in contact with the bottom wall of the limiting groove 311.

[0053] In this embodiment, the position detection element 40 is mounted on the support mechanism 30. The position detection element 40 may be a contact sensor, an infrared sensor, or a pressure sensor.

[0054] The position detection component 40 and the drive component of the lifting mechanism 20 can establish a communication connection via wired or wireless means, forming a simple closed-loop control circuit. When the drive component starts, the drive shaft 21 drives the support mechanism 30 to move upward. As the limiting groove 311 gradually approaches and lifts the mast 50, the position detection component 40 continuously monitors its status. Once the mast 50 is lifted to be completely in contact with the bottom wall of the limiting groove 311, the position detection component 40 senses the presence of the mast 50 and immediately sends a stop signal to the drive component. Upon receiving the signal, the drive component automatically cuts off the power output, causing the drive shaft 21 to stop moving, thereby avoiding excessive lifting that could cause equipment impact, deformation of the mast 50, or damage to the support mechanism 30. This solution, by setting the position detection component 40, achieves intelligent judgment and precise positioning during the lifting process, further improving the efficiency of the mast 50 assembly and disassembly operations.

[0055] Combination Figure 1 As shown, in one embodiment of this utility model, the position detection element 40 is a contact position sensor and is movably mounted on the support mechanism 30.

[0056] In this embodiment, the contact position sensor refers to a detection device that triggers a signal output through physical contact. Specifically, it can be implemented using a mechanical microswitch or a pressure sensor. Its contact end directly contacts the surface of the rod 50 to determine the actual contact state. Specifically, it can be installed at the bottom of the support base 31, with its contact end facing the supporting area of ​​the limiting groove 311 and flush with the bottom wall of the limiting groove 311. When the support mechanism 30 moves upward under the drive of the drive shaft 21 and gradually lifts the rod 50, the outer wall of the rod 50 contacts the bottom wall of the limiting groove 311. At this time, the contact end of the contact position sensor also contacts the rod 50, triggering a contact signal inside the sensor. After this signal is transmitted to the drive component control unit, the power output is immediately cut off, causing the drive shaft 21 to stop moving.

[0057] When installing the machine rod 50, the operator can adjust the position sensor to a safe position of retraction or downward placement in advance to ensure that the contact end of the position sensor does not come into contact with the outer wall of the machine rod 50, thereby avoiding the position sensor from accidentally triggering the "fitted" signal.

[0058] Combination Figure 1 As shown, in one embodiment of this utility model, the drive shaft 21 is a lead screw, and the drive component also includes a motor 23. The motor 23 is driven and connected to the lead screw. The lead screw is installed on the frame 10 and driven and connected to the support mechanism 30. Under the drive of the motor 23, the support mechanism 30 is moved.

[0059] And / or, the drive shaft 21 is a lead screw, and the drive component also includes a rocker arm 22. The rocker arm 22 is driven and connected to the lead screw. The lead screw is mounted on the frame 10 and driven and connected to the support mechanism 30. Rotating the rocker arm 22 drives the lead screw to drive the support mechanism 30 to move.

[0060] In this embodiment, the lead screw refers to a transmission component that converts rotary motion into linear motion through a threaded structure. Its function is to transmit the rotational power of the drive component to the support mechanism 30, thereby achieving precise control of height adjustment. The motor 23 can be implemented using a servo motor 23 or a stepper motor 23. Its function is to provide automated rotational driving force for the lead screw, reducing the intensity of manual operation. When the motor 23 starts, it drives the lead screw to rotate, and the support mechanism 30 rises or falls vertically under the rotation of the lead screw, thus achieving height adjustment.

[0061] When the power unit for the drive component is limited to or not limited to a motor 23, the lifting mechanism 20 can also be equipped with a rocker arm 22 as a drive component. The rocker arm 22 is a rotary operating component with a handle, whose function is to manually rotate the drive screw to complete the height adjustment of the support mechanism 30. This structure does not require an external power source, is simple in structure, and is not affected by the power supply.

[0062] The two drive methods described above can be configured individually according to actual usage requirements, or both motor 23 drive and rocker arm 22 drive can be set on the same device to form an "electric + manual" dual-mode lifting mechanism 20. Under normal circumstances, motor 23 drive is used to improve efficiency; when there is a power failure or fine adjustment is required, it can be switched to manual rocker arm 22 operation to improve the flexibility and emergency response capability of the device. Regardless of the method used, the lead screw can smoothly convert the rotational motion into linear motion, driving the support mechanism 30 to accurately adjust the height, ensuring that the docking process between the limit groove 311 and the lifting rod 50 is safe and controllable, effectively meeting the operational requirements for disassembly, assembly and transportation of the lifting rod 50 under different working conditions.

[0063] Combination Figure 2 As shown, in one embodiment of this utility model, the lifting mechanism 20 and the support mechanism 30 are each provided in two sets. Each lifting mechanism 20 is driven to connect with a support mechanism 30. The two support mechanisms 30 are arranged axially at intervals along the limiting groove 311, and the machine rod 50 is simultaneously supported in the two limiting grooves 311.

[0064] In this embodiment, both the lifting mechanism 20 and the support mechanism 30 are provided in two sets. Each set of lifting mechanism 20 is drivenly connected to the corresponding support mechanism 30. The two support mechanisms 30 are spaced apart, so that the boom 50 can be supported simultaneously in two limiting grooves 311 during disassembly, assembly, and transportation, forming a two-point support structure. This arrangement significantly improves the support stability of the long, heavy boom 50, effectively avoiding cantilever stress, bending deformation, or center of gravity shift caused by single-point support, and ensuring the balance and safety of the boom 50 during lifting and movement.

[0065] Furthermore, since the two lifting mechanisms 20 can be controlled independently, the two support mechanisms 30 can not only be adjusted in height separately, but also adjust the support angle of their respective fixing parts 332 according to the actual working conditions. When faced with minor deviations in the installation position or slight bending of the mast 50 due to long-term use, the lifting stroke of one of the lifting mechanisms 20 can be adjusted individually to raise or lower the limiting groove 311 of the corresponding support mechanism 30 appropriately, achieving dynamic compensation for the support posture. This ability to adjust the angle separately allows the two support points to adaptively conform to the actual axis of the mast 50, avoiding additional stress caused by forced alignment and preventing jamming or structural damage to the mast 50 during disassembly.

[0066] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
