Technical Field

[0001] This utility model relates to a stop structure, and more particularly to a buffer energy-absorbing stop structure at the end of a ground rail, belonging to the technical field of ground rail accessories. Background Technology

[0002] In automated production lines, multi-level parking garages, and logistics sorting systems, floor rails serve as the guiding foundation for moving components (such as railcars, sliders, and transport trolleys) and are widely used. When moving components run along the floor rails, if they collide with the ends of the floor rails due to control failures, excessive inertia, or operational errors, it can easily cause damage to the moving components, deformation of the floor rails, or even safety accidents. Therefore, stop structures are required.

[0003] The existing end blocks of the ground rail are mostly fixed to the surface of the ground rail by bolts or welding, which requires the use of special tools to disassemble or replace them, thus increasing the difficulty of subsequent maintenance. Utility Model Content

[0004] The purpose of this utility model is to provide a buffer energy-absorbing block structure at the end of the ground rail, so as to solve the problem mentioned in the background art that the existing ground rail end blocks are mostly fixed to the ground rail surface by bolts or welded, and disassembly and replacement require special tools, which increases the difficulty of subsequent maintenance.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a ground rail end buffer energy-absorbing block structure, including a rail, a locking seat engaged on one side of the top of the rail, two sliding rods slidably mounted on the top of the locking seat, a support block fixed between the two sliding rods, a rubber block on one side of the support block, a spring fixed between the locking seat and the support block, and the spring sleeved on the outside of the sliding rods, a screw threadedly connected to the middle of the locking seat through a limiting nut, a pressure plate rotatably mounted on one end of the screw, a locking block engaging with the rail on one side of the pressure plate, a box at the bottom of the pressure plate, two symmetrically arranged inserts for insertion into the rail inside the box, and an adjustment component inside the box.

[0006] As a preferred technical solution of this utility model, the bottom end of the track is fixedly provided with a mounting base, the surface of the mounting base is provided with a plurality of evenly spaced mounting holes, the inside of the track is provided with a lead screw, the surface of the lead screw is threadedly connected to a movable seat through a lead screw nut, and the surface of the movable seat is provided with a plurality of evenly spaced through holes.

[0007] As a preferred technical solution of this utility model, two support rods are symmetrically slidably provided at the bottom of the movable seat. Both ends of the support rods are fixedly connected to the inner wall of the track. A forward and reverse motor is fixedly provided on one side of the track. The output shaft of the forward and reverse motor passes through the track and is fixedly connected to one end of the lead screw.

[0008] As a preferred technical solution of this utility model, the top of the card holder is provided with a shock-absorbing component, the shock-absorbing component includes a movable plate, the movable plate is slidably disposed at the top of the card holder, one end of the two sliding rods is fixedly connected to one side of the movable plate, and a shock absorber is fixedly disposed between the movable plate and the card holder.

[0009] As a preferred technical solution of this utility model, two limiting rods are symmetrically fixed on the other side of the support block. One end of the limiting rod passes through the card seat and extends to the outside of the card seat. The surface of the rubber block is fixedly connected to one side of the support block by four bolts.

[0010] As a preferred embodiment of this utility model, two guide rods are symmetrically fixed on the other side of the pressure plate, the guide rods are slidably connected to the card seat, and a first throttle is fixed on the other end of the screw.

[0011] As a preferred technical solution of this utility model, the adjustment component includes a second lead screw, which is rotatably disposed inside the housing, and the threads at both ends of the second lead screw have opposite directions.

[0012] As a preferred technical solution of this utility model, a positioning rod is slidably provided between the two insert blocks, and both ends of the positioning rod are fixedly connected to the inner wall of the box. One end of the second lead screw passes through the box and is fixedly provided with a second throttle.

[0013] Compared with related technologies, the rail end buffer energy-absorbing block structure provided by this utility model has the following beneficial effects:

[0014] 1. By engaging the threaded screw in the middle of the card holder with the limit nut, and with the first rotary handle fixed at the other end of the screw, the operator can drive the screw to extend or retract without the need for special tools such as wrenches or screwdrivers. This, in turn, moves the pressure plate, causing the card block on one side of the pressure plate to engage tightly with the track or disengage. At the same time, the two insert blocks inside the box engage with the track, forming a double fixing structure of "engagement and insertion". This ensures that the card holder does not shift during impact and avoids the problems of traditional welding fixation which cannot be disassembled and traditional single bolt fixation which requires special tools to unscrew. The time for installing or disassembling the entire block structure is greatly shortened.

[0015] 2. The rubber block set on one side of the support block can directly contact the impact component, initially attenuating the rigid impact. At the same time, the spring sleeved on the outside of the slide rod between the card seat and the support block can further absorb the impact energy through elastic deformation. The double buffer structure effectively reduces the impact damage to the track and moving parts and improves the energy absorption and buffering effect. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-6This utility model provides a ground rail end buffer energy-absorbing block structure, including a rail 1, a locking seat 2 engaged on one side of the top of the rail 1, two sliding rods 3 slidably mounted on the top of the locking seat 2, a support block 4 fixed between the two sliding rods 3, a rubber block 5 on one side of the support block 4, and a spring 6 fixed between the locking seat 2 and the support block 4. The rubber block 5 on one side of the support block 4 can directly contact the impacting component, initially attenuating rigid impact. Simultaneously, the spring 6, sleeved on the outside of the sliding rods 3 between the locking seat 2 and the support block 4, can further absorb impact energy through elastic deformation. This double buffer structure effectively reduces impact damage to the rail 1 and moving components, improving the energy absorption and buffering effect. Furthermore, the spring 6 is sleeved on the outside of the sliding rods 3. A screw 8 is threadedly connected to the middle of the locking seat 2 via a limiting nut. One end of the screw 8 is rotatably mounted... The pressure plate 7 has one side connected to the track 1 via a locking block 9. The bottom of the pressure plate 7 has a housing 10, inside which are two symmetrically arranged insert blocks 11 that connect to the track 1. The screw 8 and the limit nut engage to move the pressure plate 7, causing the locking block 9 on one side of the pressure plate 7 to engage tightly with the track 1. This, combined with the locking seat 2, compresses and fixes the track 1. Simultaneously, the two insert blocks 11 inside the housing 10 connect to the track 1, forming a dual "locking and plugging" fixing structure. This significantly improves the connection stability between the locking seat 2 and the track 1, preventing the locking seat 2 from shifting during impact, thus facilitating the installation or removal of the buffer energy-absorbing block structure. The housing 10 also has an adjustment component 12 inside, which allows the two insert blocks 11 to move synchronously for adjustment, making it more convenient to use.

[0025] A shock-absorbing assembly 13 is provided at the top of the card holder 2. The shock-absorbing assembly 13 includes a movable plate 1301, which is slidably mounted on the top of the card holder 2. One end of each of the two sliding rods 3 is fixedly connected to one side of the movable plate 1301. A shock absorber 1302 is fixedly mounted between the movable plate 1301 and the card holder 2. Two limiting rods 1303 are symmetrically fixed on the other side of the support block 4. One end of each limiting rod 1303 passes through the card holder 2 and extends to the outside of the card holder 2. The surface of the rubber block 5 is fixedly connected to one side of the support block 4 by four bolts 16. The shock-absorbing assembly 13 is used to achieve this. The shock absorber 1302 fixed between the movable plate 1301 and the card seat 2, together with the spring 6 originally sleeved on the outside of the slide rod 3, forms a dual shock absorption structure of "spring 6 elastic buffer plus shock absorber 1302 damping energy absorption", which can further attenuate the vibration generated by high frequency or large load impact. Compared with the single spring 6 buffer, the impact energy absorption efficiency is improved. The two limiting rods 1303 symmetrically fixed on the other side of the support block 4 extend through the card seat 2 to the outside, which can limit the sliding of the support block 4. The rubber block 5 is connected by bolts 16, so that the rubber block 5 can be replaced.

[0026] Two guide rods 15 are symmetrically fixed on the other side of the pressure plate 7. The guide rods 15 are slidably connected to the card seat 2. The other end of the screw 8 is fixed with a first rotary handle 14. The two guide rods 15 symmetrically fixed on the other side of the pressure plate 7 are slidably connected to the card seat 2. When the screw 8 is rotated to drive the pressure plate 7 to move, the two guide rods 15 can provide guidance for the pressure plate 7. The first rotary handle 14 can drive the screw 8 to rotate.

[0027] The adjusting assembly 12 includes a second lead screw 1201, which is a trapezoidal lead screw structure with a self-locking effect. The second lead screw 1201 is rotatably mounted inside the housing 10, and the threads at both ends of the second lead screw 1201 rotate in opposite directions. A positioning rod 1202 is slidably provided between the two inserts 11, and both ends of the positioning rod 1202 are fixedly connected to the inner wall of the housing 10. One end of the second lead screw 1201 passes through the housing 10 and is fixedly provided with a second handle 1203. By using the adjusting assembly 12 and the opposite threads at both ends of the second lead screw 1201, rotating the second lead screw 1201 can drive the two inserts 11 to move synchronously in opposite directions. With the sliding guide of the inserts 11 by the positioning rod 1202, the distance between the two inserts 11 can be adjusted to ensure that the inserts 11 are accurately inserted into the track 1. The second handle 1203 provides the operator with a convenient point of force to easily rotate the second lead screw 1201.

[0028] A mounting base 21 is fixedly installed at the bottom end of the track 1. The surface of the mounting base 21 has several evenly spaced mounting holes 22. A lead screw 17 is rotatably installed inside the track 1. A movable seat 18 is threadedly connected to the surface of the lead screw 17 via a lead screw nut. The surface of the movable seat 18 has several evenly spaced through holes. Two support rods 19 are symmetrically slidably installed at the bottom of the movable seat 18. Both ends of the support rods 19 are fixedly connected to the inner wall of the track 1. A forward / reverse motor 20 is fixedly installed on one side of the track 1, and the output shaft of the forward / reverse motor 20 passes through it. The track 1 is fixedly connected to one end of the lead screw 17; the mounting base 21 fixed at the bottom of the track 1 has several evenly spaced mounting holes 22 on its surface, which can be adapted to the fastener fixing requirements in different installation scenarios; the lead screw 17 is driven to rotate by the output shaft of the forward and reverse motor 20, which drives the movable seat 18 on the surface of the lead screw 17 to move along the length direction of the track 1, and cooperates with the guiding role of the two symmetrically sliding support rods 19 at the bottom of the movable seat 18; the movable seat 18 has several evenly spaced through holes on its surface, which are used to install the equipment with fasteners.

[0029] In use, first determine the laying position of track 1 according to the installation requirements of the actual use scenario, and attach the mounting base 21 at the bottom of track 1 to the preset mounting surface (such as the ground or equipment frame support surface). Using the several evenly spaced mounting holes 22 on the surface of the mounting base 21, select appropriate fasteners (such as expansion screws, high-strength screws, etc.) to fasten the mounting base 21 to the mounting surface. Then, through the several evenly spaced through holes on the surface of the movable base 18, use fasteners to fix the equipment to be installed (such as a conveyor trolley, translation mechanism, etc.) to the movable base 18.

[0030] When the card holder 2 is engaged with the preset buffer position near the top end of the track 1, the first handle 14 is rotated. Since the screw 8 is threadedly engaged with the limiting nut on the card holder 2, and the pressure plate 7 is rotatably connected to the screw 8 and slidably connected to the card holder 2 through the guide rod 15, when the first handle 14 drives the screw 8 to rotate, it will drive the pressure plate 7 to move towards one side of the track 1 along the extension direction of the guide rod 15. Continue to rotate the first handle 14 until the card block 9 on one side of the pressure plate 7 is tightly engaged with the outer wall of the track 1. At this time, the card holder 2 and the pressure plate 7 form a bidirectional compression on the track 1, and the card holder 2 and the track 1 are initially engaged and fixed.

[0031] Then, rotate the second handle 1203 on the outside of the box 10. The second handle 1203 drives the second lead screw 1201 inside the box 10 to rotate. Since the second lead screw 1201 is a trapezoidal lead screw structure (with self-locking effect) and the threads at both ends are opposite, and both insert blocks 11 are threadedly connected to the second lead screw 1201 and slide in cooperation with the positioning rod 1202, when the second lead screw 1201 rotates, it will drive the two insert blocks 11 to move synchronously towards each other along the positioning rod 1202. Continue to rotate the second handle 1203 until the two insert blocks 11 are inserted into the preset insertion slots on the side wall of the track 1. At this time, the card seat 2 and the track 1 form a double fixing structure of "card block 9 engaging and insert block 11 engaging", which completely avoids the card seat 2 from shifting when impacted.

[0032] When the movable seat 18 on track 1 moves towards the end of track 1 and impacts, the rubber block 5 on one side of the support block 4 first contacts the impacting component, and the elastic deformation of the rubber block 5 initially attenuates the rigid impact. As the impact force continues to be transmitted, the support block 4 slides along the slide rod 3 towards the card seat 2, compressing the spring 6 sleeved on the outside of the slide rod 3. The spring 6 further absorbs the impact energy through elastic deformation. At the same time, the support block 4 drives the slide rod 3 to push the movable plate 1301 to move. The movable plate 1301 squeezes the shock absorber 1302. The shock absorber 1302 attenuates the vibration generated by high-frequency or high-load impacts through damping, forming a triple buffering effect of "initial buffering by the rubber block 5, elastic energy absorption by the spring 6, and damping and shock absorption by the shock absorber 1302", which effectively reduces the impact damage to track 1 and moving parts.

[0033] If the buffer energy-absorbing block body needs to be disassembled, first turn the second handle 1203 to disengage the insert 11 from the insertion hole of the track 1, then turn the first handle 14 in the opposite direction to disengage the clamping block 9 of the pressure plate 7 from the track 1, and finally remove the clamping seat 2 from the top of the track 1. The operation is convenient. Finally, the rubber block 5 and the spring 6 should be inspected and replaced regularly.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
