Description

Technical Field

[0001] This application belongs to the field of mechanical conveying safety protection technology, specifically relating to a mechanical limiting and buffering device. Background Technology

[0002] On automated production lines such as those used in automobile manufacturing, car bodies are typically transported by skids and move along conveyor lines. When the skid carrying the car body reaches a specific workstation (such as an interface workstation), it needs to stop precisely to allow for subsequent operations. Currently, the most common stopping method relies on the brake system of the conveyor motor at the workstation for braking.

[0003] In existing technologies, the brake system of the conveyor motor is prone to failure due to mechanical malfunctions, electrical failures, or prolonged wear during actual operation. Once the brake fails, the skid, under inertia, will continue to pull the vehicle out of its designated position, easily leading to serious safety accidents such as the vehicle falling from a height or colliding with surrounding equipment. This not only causes significant property damage but also endangers the personal safety of on-site operators, posing a significant safety hazard. Therefore, there is an urgent need for a mechanical limiting and buffering device that can reliably stop and buffer the skid in the event of brake failure, preventing it from surging out and thus eliminating the safety hazard.

[0004] To address the above issues, this application designs a mechanical limiting and buffering device to solve the technical problem that, in the event of brake failure, the skid will continue to carry the vehicle body out of the designated work position due to inertia, posing a safety hazard. Utility Model Content

[0005] This application aims to address at least one of the technical problems existing in the prior art or related technologies.

[0006] Therefore, this application designs a mechanical limiting buffer device to prevent the skid from continuing to rush out of the predetermined work position under the action of inertia when the brake fails, and to reduce safety hazards.

[0007] This application provides a mechanical limiting and buffering device, comprising: a support plate; an inclined support plate fixed to the upper left of the support plate; a slider disposed on the right side of the support plate; a nylon buffer block disposed on the right side of the slider; a height adjustment assembly disposed on the right side of the support plate to adjust the buffering height of the nylon buffer block on the skid; a buffer plate disposed between the slider and the nylon buffer block, with a mounting groove on the right side of the buffer plate; a mounting plate fixed to the left side of the nylon buffer block and inserted into the mounting groove; a pressure alarm fixed to the upper end of the slider; a pressure sensing buffer assembly disposed between the slider and the buffer plate for monitoring the impact force on the nylon buffer block and providing elastic buffering protection for the skid; and an elastic snap-fit ​​assembly disposed on the upper and lower parts of the mounting plate for snapping the limiting mounting plate and facilitating the disassembly and replacement of the nylon buffer block.

[0009] In some possible embodiments, the support plate has a groove on its right side, and the slider is slidably connected to the groove.

[0010] In some possible embodiments, the lower ends of both the support plate and the inclined plate are fixed with bases, and the lower end of the lead screw is rotatably connected to the upper part of the adjacent base.

[0011] In some possible embodiments, the pressure sensing buffer assembly includes: a pressure sensor fixed to the middle of the right side of the slider, the pressure sensor being signal-connected to a pressure alarm; a pressure plate connected to the pressure sensing end of the pressure sensor; at least two first spring buffer rods, all fixed between the pressure plate and the buffer plate; and several second spring buffer rods, all fixed between the slider and the buffer plate.

[0012] In some possible embodiments, a battery is fixedly mounted on the surface of the slider, and both the pressure sensor and the pressure alarm are electrically connected to the battery.

[0013] In some possible embodiments, the elastic snap-fit ​​assembly includes: pull blocks, respectively disposed on the upper and lower parts of the buffer plate; pull rods, each fixed to the inner side of adjacent pull blocks, with shrinkage grooves opened on the upper and lower parts of the inner wall of the mounting groove, and the pull rods sliding through the buffer plate into the adjacent shrinkage grooves; inclined snap-fit ​​blocks, each fixed to the end of adjacent pull rods, with snap-fit ​​grooves opened on the upper and lower ends of the mounting plate, and the inclined snap-fit ​​blocks snapping into the snap-fit ​​grooves; and a return spring, one end fixed to the outside of the inclined snap-fit ​​block, and the other end fixed deep inside the inner wall of the shrinkage groove.

[0014] In some possible embodiments, a reinforcing rod is fixed between the support plate and the inclined support plate.

[0015] Compared with the prior art, the technical solution provided in this application has at least the following beneficial effects: This application provides a mechanical limit buffer device, which offers an independent mechanical safety barrier. It effectively blocks and buffers the skid when the conveyor motor brake fails, preventing accidents and demonstrating high safety and reliability. Furthermore, the height of the nylon buffer block can be easily adjusted via a lead screw to accommodate the buffering needs of skids of different heights, offering strong versatility. The combination of a pressure sensor and a pressure alarm allows for real-time monitoring of the impact force and triggers an alarm when limits are exceeded, facilitating timely detection and handling of abnormal situations and enabling preventative maintenance.

Detailed Implementation

[0019] To better understand the above-mentioned objectives, features, and advantages of this application, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0020] Many specific details are set forth in the following description in order to provide a full understanding of this application. However, this application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of this application is not limited to the specific embodiments disclosed below.

[0021] The following reference Figures 1 to 6 This application describes a mechanical limiting buffer device provided according to some embodiments.

[0022] Please see Figures 1 to 6 The mechanical limiting buffer device provided in some embodiments of this application includes, in some embodiments: a support plate 1; an inclined support plate 2 fixed to the upper left of the support plate 1; a slider 3 disposed to the right of the support plate 1; and a nylon buffer block 4 disposed to the right of the slider 3.

[0023] In this embodiment, the buffer device is fixed to the position where the skid is to be pushed out by the base 10. Therefore, this application is equivalent to providing an independent mechanical safety barrier. In actual use, once the conveyor motor brake fails, the skid slides under the action of inertia and is blocked and limited by the nylon buffer block 4. Therefore, it can effectively block and buffer the skid when the conveyor motor brake fails, prevent safety accidents from happening, and has high safety and reliability.

[0024] In some embodiments, a height adjustment component is located on the right side of the support plate 1 to adjust the buffer height of the nylon buffer block 4 on the skid; the height adjustment component includes: a lead screw 301 located on the right side of the support plate 1, with the slider 3 threadedly sleeved around the lead screw 301; a fixing plate 302 fixed to the upper right part of the support plate 1, with the lead screw 301 rotatably extending through the fixing plate 302; an operating handle 303 fixed to the upper end of the lead screw 301; a sliding groove 304 is opened on the right side of the support plate 1, with the slider 3 slidably connected to the sliding groove 304; a base 10 is fixed to the lower end of both the support plate 1 and the inclined support plate 2, and the lower end of the lead screw 301 is rotatably connected to the upper part of the adjacent base 10.

[0025] In this embodiment, by operating the handle 303 to rotate the lead screw 301, the lead screw 301 will drive the slider 3 to slide up and down along the slide groove 304. Therefore, the slider 3 will drive the nylon block to move up and down together. Thus, the height of the nylon buffer block 4 can be easily adjusted by operating the lead screw 301, which is beneficial for adapting the device to the buffering needs of different models of height skids and has strong versatility.

[0026] In some embodiments, a pressure alarm 8 is fixed to the upper end of the slider 3; a pressure sensing buffer assembly is disposed between the slider 3 and the buffer plate 5, used to monitor the impact force on the nylon buffer block 4 and provide elastic buffer protection for the skid; the pressure sensing buffer assembly includes: a pressure sensor 801, fixed to the middle of the right side of the slider 3, the pressure sensor 801 being signal-connected to the pressure alarm 8; a pressure plate 802, connected to the pressure sensing end of the pressure sensor 801; at least two first spring buffer rods 803, all fixed between the pressure plate 802 and the buffer plate 5; and several second spring buffer rods 804, all fixed between the slider 3 and the buffer plate 5.

[0027] In this embodiment, by combining the pressure sensor 801 and the pressure alarm 8, when the nylon buffer block 4 limits the buffer skid, the first spring buffer rod 803 and the second spring buffer rod 804 contract under the impact force. At the same time, the pressure plate 802 presses the pressure sensor 801. When the pressure exceeds the preset pressure value of the pressure sensor 801 (the preset pressure value depends on the actual use, and the pressure sensor 801 is a technically mature instrument, so it will not be described in detail in this application), the pressure sensor 801 will control the pressure alarm 8 to sound an alarm. Therefore, it can monitor the magnitude of the impact force in real time and alarm when the limit is exceeded, which is convenient for timely detection and handling of abnormal situations and facilitates preventive maintenance. Furthermore, by setting the nylon buffer block 4 and combining it with multiple first spring buffer rods 803 and second spring buffer rods 804 for elastic buffering, the impact energy can be effectively absorbed and dissipated, reducing impact damage to the equipment and the skid, and the buffering performance is good.

[0028] In some embodiments, a buffer plate 5 is disposed between the slider 3 and the nylon buffer block 4, and a mounting groove 6 is formed on the right side of the buffer plate 5; a mounting plate 7 is fixed to the left side of the nylon buffer block 4, and the mounting plate 7 is inserted into the mounting groove 6; an elastic snap-fit ​​assembly is disposed at the upper and lower parts of the mounting plate 7, used to snap-fit ​​and limit the mounting plate 7 and facilitate the disassembly and replacement of the nylon buffer block 4; each elastic snap-fit ​​assembly includes: pull blocks 9, respectively disposed at the upper and lower parts of the buffer plate 5; and pull rods 901, each fixed within an adjacent pull block 9. On the side, the upper and lower parts of the inner wall of the mounting groove 6 are provided with shrinkage grooves 902, and the pull rods 901 are slidably inserted into the adjacent shrinkage grooves 902 through the buffer plate 5; the inclined blocks 903 are fixed to the ends of the adjacent pull rods 901, and the upper and lower ends of the mounting plate 7 are provided with slots 905, and the inclined blocks 903 are engaged in the slots 905; one end of the return spring 904 is fixed to the outside of the inclined blocks 903, and the other end of the return spring 904 is fixed deep in the inner wall of the shrinkage groove 902.

[0029] In this embodiment, when it is necessary to replace the damaged nylon buffer block 4, with the locking block engaged in the slot 905, the pull rod 901 and the inclined locking block 903 are pulled outward by the pull block 9. The inclined locking block 903 will compress the return spring 904, thereby moving the inclined locking block 903 out of the slot 905. Therefore, the mounting plate 7 can be easily removed from the mounting slot 6, which facilitates the easy removal of the damaged nylon buffer block 4. When installing a new nylon buffer block 4, the mounting plate 7 is directly inserted into the mounting slot 6. During this process, the mounting plate 7 will move along the inclined locking block. The inclined surface of 903 pushes the inclined locking block 903 into the shrinkage groove 902, and the inclined locking block 903 compresses the return spring 904. When the inclined locking block 903 is aligned with the groove of the slot 905, the rebound force of the return spring 904 will cause the inclined locking block 903 to automatically lock into the slot 905, preventing the mounting plate 7 from falling out of the mounting groove 6, and facilitating the convenient installation of the new nylon buffer block 4. In summary, since the nylon buffer block 4 is a vulnerable part, the elastic locking component enables quick disassembly and replacement, simplifies replacement, and reduces maintenance costs and time.

[0030] In summary, this application provides an effective mechanical stop and buffer skid to prevent the skid from running off the workstation when the conveyor motor brake fails. It also features height adjustment, buffer force monitoring, and easy replacement of buffer components, making it safe, reliable, and highly practical.

[0032] In this embodiment, by providing a storage battery 11, it is beneficial to supply power to the pressure sensor 801 and the pressure alarm 8, effectively ensuring that the pressure sensor 801 and the pressure alarm 8 are powered on and working normally.

[0033] In some embodiments, a reinforcing rod 12 is fixed between the support plate 1 and the inclined support plate 2.

[0034] In this embodiment, a stable structure consisting of a support plate 1, an inclined support plate 2, a reinforcing rod 11, and a base 10 is adopted to ensure that the device can withstand a large impact force.
