Description

Technical Field

[0001] This utility model relates to the field of intelligent warehousing equipment technology, and in particular to a four-way vehicle track joint noise reduction module. Background Technology

[0002] The four-way shuttle track joint noise reduction module is a key auxiliary component of the four-way shuttle track system. Its core function is to fill the gaps at the track joints, absorbing the impact energy of the wheels through the buffering effect of elastic materials, while using sound insulation structures to block noise transmission. This solves the "clicking" sound and vibration problem caused by the collision between the wheels and the track joints when the four-way shuttle is running at high speed. This module must have good elastic recovery and wear resistance, and be compatible with four-way shuttle tracks of different specifications. It is an important piece of equipment for improving the operational stability of intelligent warehousing systems and reducing noise pollution.

[0003] However, existing four-way vehicle track joint noise reduction modules have significant shortcomings in practical use.

[0004] On the one hand, the noise reduction effect is poor and the stability is insufficient. Traditional noise reduction modules mostly use a single rubber pad design, which has poor elasticity and recovery, and the gaps at the track joints are prone to increase.

[0005] On the other hand, it has low adaptability and is complicated to install and maintain. Traditional modules have fixed dimensions, and need to be customized when changing to different specifications of tracks, resulting in poor adaptability. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a four-way vehicle track joint noise reduction module, which overcomes the deficiencies of existing technologies and effectively solves the problems of poor noise reduction effect, insufficient stability, low adaptability, and cumbersome installation and maintenance of existing modules.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: A four-way vehicle track joint noise reduction module includes an installation mechanism. The top of the installation mechanism is connected to a connecting mechanism. The installation mechanism includes a polyurethane pad and fixing components respectively connected to the outer walls of both sides of the polyurethane pad. The fixing components include a fixing plate, a fixing rod welded and fixed to the outer wall of the fixing plate near the polyurethane pad, and hooks and fixing blocks welded and fixed to the top of the outer wall away from the polyurethane pad. The connecting mechanism includes a connecting plate, a positioning protrusion welded and fixed to the top of the connecting plate, an inclined pad inserted into the top of the positioning protrusion, an extension block connected to the back of the inclined pad, and a lap block welded and fixed to the top of the back of the extension block.

[0008] Furthermore, the interior of the polyurethane pad has a honeycomb structure, and both outer walls of the polyurethane pad are provided with insertion holes that can be inserted into the fixing rod.

[0009] The polyurethane pads are made of high-density polyurethane material, and the honeycomb structure can improve elasticity and sound insulation performance; the insertion holes and fixing rods are connected to ensure that the fixing components are firmly connected to the polyurethane pads without loosening.

[0010] Furthermore, the fixing block is located above the hook, and positioning holes are provided at both ends of the top of the fixing block.

[0011] Both the fixing block and the hook are made of steel. The positioning hole of the fixing block is used for positioning the connecting mechanism, and the hook can hook onto the edge of the track to enhance the stability of the module and the track and prevent the module from shifting.

[0012] Furthermore, connecting rods are welded and fixed at the four bottom corners of the connecting piece, and the connecting rods and positioning holes are interlocked.

[0013] The connecting plate is made of stainless steel, and the connecting rod is inserted into the positioning hole to ensure precise alignment between the connecting mechanism and the installation mechanism; the surface of the connecting rod is nickel-plated to improve corrosion resistance and prevent rusting and jamming caused by humid environments on the track.

[0014] Furthermore, the extension block has two plug rods welded and fixed to both ends of its outer wall near the inclined pad, and the plug rods and the inclined pad form a plug-in fit.

[0015] The extension block is made of engineering plastic. The insertion rod and the inclined pad are inserted into the insertion hole. The insertion depth of the extension block can be adjusted according to the width of the track joint to adapt to track joints with different gaps.

[0016] Furthermore, the top of the inclined pad is an inclined surface, and the inclined pad is made of polytetrafluoroethylene. A rubber strip is glued and fixed to the bottom of the block. The block is placed on the top edge of the track, and the rubber strip is in close contact with the track surface.

[0017] The inclined surface design facilitates a smooth transition of the four-way vehicle wheels to the track joints. The low coefficient of friction of the PTFE material reduces wear between the wheels and the pads, extending the wheel's service life. The rubber strips increase the friction between the pads and the track, preventing lateral displacement of the modules and buffering vibrations when the four-way vehicle passes by, further improving operational stability.

[0018] The beneficial effects of this utility model are as follows: With excellent noise reduction and strong stability, it solves the problems of poor noise reduction and insufficient stability of traditional modules through composite buffer and multiple fixing structures. The honeycomb structure of polyurethane pads and the low friction design of inclined pads work together to significantly reduce noise. The triple fixing of hooks to the edge of the track mounting frame, rubber strips to increase friction, and fixing rods to insert and position reduces the loosening rate of modules, reduces vibration amplitude, reduces wear rate of tracks and wheels, and extends service life. With strong adaptability and convenient maintenance, relying on adjustable structure and modular design, it improves the poor adaptability and complicated maintenance of traditional modules. The extension block can be adjusted to the insertion depth to adapt to track joints of different widths. The quick plug-in design of the connection mechanism and the installation mechanism can adapt to tracks of different widths, improving adaptability compared to traditional modules. There is no need to remove track bolts during installation, and only worn parts need to be replaced during maintenance, without replacing the whole system, reducing maintenance costs and meeting the efficient operation and maintenance needs of intelligent warehousing systems.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Example

[0022] Reference Figure 1-4 A four-way vehicle track joint noise reduction module includes an installation mechanism 1, a connecting mechanism 2 connected to the top of the installation mechanism 1, the installation mechanism 1 including a polyurethane pad 3, and fixing components 4 respectively connected to the outer walls of both sides of the polyurethane pad 3, the fixing components 4 including a fixing piece 5, a fixing rod 6 welded and fixed to the outer wall of the fixing piece 5 near the polyurethane pad 3, and hooks 7 and fixing blocks 8 respectively welded and fixed to the top of the outer wall away from the polyurethane pad 3. The connecting mechanism 2 includes a connecting piece 9, a positioning protrusion 11 welded and fixed to the top of the connecting piece 9, an inclined pad 12 inserted into the top of the positioning protrusion 11, an extension block 13 connected to the back of the inclined pad 12, and a lap block 15 welded and fixed to the top of the back of the extension block 13.

[0023] The polyurethane pad 3 has a honeycomb structure inside. Both outer walls of the polyurethane pad 3 have insertion holes that interlock with the fixing rod 6. The polyurethane pad 3 is made of high-density polyurethane material with a Shore hardness of 60±5. The honeycomb structure improves elasticity and sound insulation performance. The insertion holes interlock with the fixing rod 6 to ensure a secure connection between the fixing component 4 and the polyurethane pad 3, preventing loosening. The fixing block 8 is located above the hook 7. Positioning holes are provided at both ends of the top of the fixing block 8. Both the fixing block 8 and the hook 7 are made of Q235 steel. The positioning holes of the fixing block 8 are used for positioning the connecting mechanism 2. The hook 7 can hook onto the edge of the track, enhancing the stability of the module and the track and preventing module displacement. Connecting rods 10 are welded to the four corners of the bottom of the connecting piece 9. The connecting rods 10 interlock with the positioning holes. The connecting piece 9 is made of 304 stainless steel. The interlocking of the connecting rods 10 with the positioning holes ensures precise alignment between the connecting mechanism 2 and the installation mechanism 1. The surface of the connecting rods 10 is nickel-plated to improve corrosion resistance and prevent rusting and jamming caused by a humid environment on the track.

[0024] Both ends of the outer wall of the extension block 13 near the inclined pad block 12 are welded and fixed with insertion rods 14. The insertion rods 14 and the inclined pad block 12 form an insertion fit. The extension block 13 is made of ABS engineering plastic. The insertion rods 14 and the insertion holes of the inclined pad block 12 are inserted and fitted. The insertion depth of the extension block 13 can be adjusted according to the width of the track joint to adapt to track joints with different gaps. The top of the inclined pad block 12 is an inclined surface. The inclined pad block 12 is made of polytetrafluoroethylene. The bottom of the mounting block 15 is glued and fixed with a rubber strip. The mounting block 15 is placed on the top edge of the track. The rubber strip is in close contact with the track surface. The inclined surface design facilitates the smooth transition of the four-way vehicle wheels to the track joint. The low coefficient of friction of the polytetrafluoroethylene material can reduce the wear between the wheels and the pad block and extend the service life of the wheels. The rubber strip can increase the friction between the mounting block 15 and the track, prevent the module from shifting laterally, and at the same time buffer the vibration when the four-way vehicle passes by, further improving the running stability.

[0025] Installation mechanism and fixing component processing: The polyurethane pad 3 adopts the molding process, with a honeycomb structure inside and holes drilled on both outer walls. The size of the pad is customized according to the width of the track. The fixing plate 5 is welded with the fixing rod 6. The side of the fixing plate 5 away from the fixing rod 6 is welded with the hook 7 and the fixing block 8. The opening of the hook 7 is polished smooth to avoid scratching the track. The top of the fixing block 8 is processed with a positioning hole and the hole wall is chamfered to facilitate the insertion of the connecting rod 10.

[0026] Assembly of connecting mechanism and buffer components: Connecting piece 9 is laser-cut, with weight-reducing hole 10 and positioning protrusion 11 machined on the top, connecting rod 10 welded to the bottom, inclined pad 12 is machined with a 15° inclined surface, polished to Ra≤0.8μm, and drilled on the back to fit with the insertion rod 14 of extension block 13; extension block 13 is welded to the back of overlapping block 13, and rubber strip 16 is glued to the bottom of overlapping block 15 with a bonding strength ≥10N / cm² to ensure that it will not fall off during long-term use.

[0027] Overall module assembly and debugging: Insert the fixing rod 6 of the fixing component 4 into the insertion hole of the polyurethane pad 3 and fix it by interference fit; insert the connecting rod 10 of the connecting mechanism 2 into the positioning hole of the fixing block 8 to complete the assembly of the installation mechanism 1 and the connecting mechanism 2; adjust the insertion depth of the extension block 13 according to the width of the track joint, which is achieved by the insertion position of the insertion rod 14 and the inclined pad 12, ensuring that the inclined pad 12 completely covers the joint gap; place the module at the track joint, hook the hook 7 onto the edge of the track, place the mounting block 15 on the top of the track, and tightly fit the rubber strip 16 against the track surface to complete the installation.

[0028] Performance testing and verification: After installation, the noise reduction effect of the test module was tested; vibration test was conducted; simulated four-way vehicle crush test was performed. The module showed no displacement or obvious wear. The elastic recovery rate of polyurethane pad 3 was ≥98%, and the wear of inclined pad 12 was ≤0.05mm, which met the design requirements.

[0029] Working principle: Module installation and positioning: During installation, first align the polyurethane pad 3 of the installation mechanism 1 with the bottom of the track joint, and hook the hooks 7 of the fixing components 4 on both sides onto the edge of the track to ensure the module is initially fixed; then insert the connecting rod 10 of the connecting mechanism 2 into the positioning hole of the fixing block 8, the positioning protrusion 11 supports the inclined pad 12, and adjust the insertion depth of the extension block 13 so that the inclined surface of the inclined pad 12 completely covers the track joint; finally, press the overlapping block 15 so that the rubber strip 16 fits tightly against the track surface to complete the module positioning. The whole process does not require disassembling the track bolts and can be completed in 5 minutes for a single installation.

[0030] Noise reduction and buffering process: When the four-way vehicle runs to the track joint, the wheel first contacts the inclined surface of the inclined pad 12. Due to the inclined surface design and low friction material, the wheel smoothly transitions to the pad surface without obvious impact. When the wheel rolls over the inclined pad 12, the pressure is transmitted to the connecting piece 9 and the polyurethane pad 3. The honeycomb structure of the polyurethane pad 3 produces elastic deformation, absorbs impact energy, and reduces vibration. At the same time, the sound insulation structure of the polyurethane pad 3 blocks the transmission of noise. Combined with the buffering effect of the rubber strip 16, a triple noise reduction buffer of "smooth transition - energy absorption - noise blocking" is achieved, ensuring that the four-way vehicle runs smoothly and with low noise.

[0031] Long-term stability and maintenance: When the four-way vehicle frequently rolls over the track, the hook 7 and the edge of the track, the friction between the rubber strip 16 and the track, and the insertion and positioning of the fixing rod 6 work together to keep the module stable. The high elastic recovery rate of the polyurethane pad 3 ensures that there is no permanent deformation after long-term use. The low wear characteristics of the inclined pad 12 extend its service life. During maintenance, if the inclined pad 12 is severely worn, it is only necessary to pull out the extension block 13, replace the new inclined pad 12, and reconnect it. Maintenance can be completed within 1 minute without replacing the entire module, which greatly reduces maintenance costs and downtime.

[0032] Adaptation and expansion: When the track specifications are changed, only the corresponding length of polyurethane pad 3 and connecting piece 9 need to be replaced. The core components of fixing component 4 and connecting mechanism 2 can be reused, reducing adaptation costs by 70%. When the width of the track joint changes, the insertion depth of extension block 13 is adjusted so that the inclined pad 12 always covers the joint. There is no need to re-customize the module, which meets the flexible change requirements of the intelligent warehousing system.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
