[0002] The three-wheel sweeper is an efficient and flexible cleaning equipment, suitable for cleaning operations in various small-scale workplaces. The three-wheel sweeper is usually composed of a water tank, a water pump, a fan, a main brush and a side brush. The garbage on the road is cleaned onto the main brush, which is then collected and sucked away by the side brush to achieve the purpose of cleaning the ground. The three-wheel sweeper is mainly used for outdoor cleaning work and can clean various grounds, including squares, parking lots, road green belts, ports, docks and other places with hard ground. It has the advantages of high cleaning efficiency, easy operation and low maintenance cost. Nowadays, the three-wheel sweeper has been widely used by sanitation, cleaning, property and corporate units.

[0003] The defects of the three-wheel sweeper in the prior art are: 1. Patent document CN209368751U discloses a sweeper, which does not have a supporting and protective function when encountering a slope or a road with complex road conditions and tilting, which can easily cause the vehicle to tilt and roll over. The low driving stability causes damage to the vehicle itself and the operator.

[0004] 2. Patent document CN218436843U discloses a front wheel shock-absorbing structure for a sweeper.

[0016] A method for using a multifunctional anti-collision and anti-rollover protection mechanism for a sweeper is applicable to a multifunctional anti-collision and anti-rollover protection mechanism for a sweeper. Preferably, the method for using the anti-collision and anti-rollover protection mechanism comprises the following steps: Step S1, when the three-wheeled sweeper encounters a slope or a road with complex road conditions and tilts, the anti-roll bracket contacts the ground to play a supporting and protective role; Step S2, the chromium carbide composite material pad contacts the ground to make the telescopic arc frame slide in the wear-resistant chromium cast iron frame, and the damper and the pressure-resistant spring buffer the extrusion force; Step S3, the reinforcing support rod supports the deformation of the anti-roll bracket when the roll protection assembly is working through the boarding pedal, so that the roll protection assembly can more stably bear the tipping force when the three-wheel sweeper tilts.

[0018] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention provides a roll protection component at the bottom of the three-wheeled sweeper body. When the three-wheeled sweeper encounters a slope or a road with complex road conditions and rolls over during use, the anti-roll bracket contacts the ground to play a supporting and protective role. The anti-roll bracket can quickly respond to the roll of the vehicle and contact the ground to form a support point to effectively prevent the vehicle from further tilting. The immediate supporting effect greatly improves the driving stability of the three-wheeled sweeper under complex road conditions and reduces the risk of rollover. When rollover occurs, the anti-roll bracket can share the weight and impact force of the vehicle, thereby reducing the damage to the vehicle itself and the operator, allowing the operator to focus more on driving operations to improve work efficiency, effectively preventing the vehicle from rolling over, reducing vehicle damage and maintenance costs caused by accidents, and contributing to the long-term operation of the three-wheeled sweeper.

[0019] 2. The present invention has a reinforcing support rod rotatably installed on the inner side of the hinge seat. The reinforcing support rod supports the deformation of the anti-roll bracket when the roll protection assembly is working through the boarding foot pedal, effectively reducing the deformation of the anti-roll bracket when subjected to the roll moment, so that the roll protection assembly can more stably bear the tipping force when the three-wheeled sweeper tilts, and enhance the stability of the roll protection assembly. The improved stability helps to ensure that the three-wheeled sweeper can maintain a more stable posture when tilting, reducing the risk of rollover. The reinforcing support rod improves the load-bearing capacity of the roll protection assembly so that the roll protection assembly can withstand more impacts when tilting. The reinforcing support rod effectively supports the anti-roll bracket, reducing its deformation and wear during the rolling process, thereby extending the service life of the roll protection assembly.

[0020] 3. The present invention installs a wear-resistant chromium cast iron frame at the bottom end of the anti-roll bracket. When the roll protection component is working, the chromium carbide composite material pad contacts the ground to make the telescopic arc frame slide in the wear-resistant chromium cast iron frame. The damper and the pressure-resistant spring buffer the extrusion force to enhance the wear resistance and impact resistance. The sliding of the telescopic arc frame in the wear-resistant chromium cast iron frame enables the anti-roll bracket to adjust its position more flexibly when subjected to the roll moment, and forms a more stable support point with the ground, thereby improving the response speed of the roll protection component and enabling the vehicle to transition more smoothly when rolling, reducing the impact on the vehicle. The damper and the pressure-resistant spring further enhance the buffering effect of the roll protection component, enabling the vehicle to stop more smoothly when rolling, avoiding damage caused by impact, and improving overall safety and reliability.

[0021] 4. The present invention installs a chromium carbide composite material pad on the inner side of the installation trough, and the chromium carbide composite material pad in the wear-resistant chromium cast iron frame at the bottom of the anti-roll bracket contacts the ground to reduce the wear of the anti-roll bracket. The chromium carbide composite material pad effectively reduces the wear when in contact with the ground, and can maintain the integrity of the anti-roll bracket during long-term use. When the roll protection component is subjected to the roll moment, the wear-resistant chromium cast iron frame can disperse the stress, reduce the force-bearing area of ​​the chromium carbide composite material pad, and thus reduce the wear. The maintenance difficulty and time are reduced, and the maintenance efficiency is improved, which helps to reduce the downtime caused by damage to the roll protection component, thereby improving the operating efficiency of the three-wheel sweeper. The convenient replacement of the chromium carbide composite material pad reduces the failure rate of the roll protection component, thereby improving the safety and reliability of the sweeper, making the three-wheel sweeper safer and more reliable on slopes and roads with complex road conditions.

For example, "connected" can be a fixed connection or a movable connection, or a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0027] See also Figure 1 , Figure 2 and Figure 3 , an embodiment provided by the present invention: a multifunctional anti-collision and anti-rollover protection mechanism for a sweeper; It includes a three-wheel sweeping machine body 1, an anti-collision large round tube 3 and an anti-roll bracket 5. A roll protection component is arranged at the bottom of the three-wheel sweeping machine body 1. The roll protection component includes a side plate connecting plate 2, an anti-collision large round tube 3, a boarding foot pedal 4 and an anti-roll bracket 5. Two sets of side plate connecting plates 2 are symmetrically mounted on the chassis of the three-wheel sweeping machine body 1 by bolts. A round tube docking groove 9 is opened through the outer side of the side plate connecting plate 2. The anti-collision large round tube 3 is embedded and installed on the inner side of the round tube docking groove 9. The boarding foot pedal 4 is symmetrically mounted on the outer end of the anti-collision large round tube 3. The anti-roll bracket 5 is symmetrically mounted on the bottom end of the anti-collision large round tube 3. During the use of the three-wheeled sweeper, especially when encountering slopes and roads with complex road conditions, there is indeed a risk of rollover. The side plate connecting plate 2 ensures the stable installation and use of the roll protection component at the bottom end of the three-wheeled sweeper body 1. The anti-collision large round tube 3 provides anti-collision protection for the outer end and the front end of the three-wheeled sweeper during use, reducing the damage to the three-wheeled sweeper body 1 caused by the collision. When the three-wheeled sweeper encounters a slope or a road with complex road conditions during use and rolls over, the anti-roll bracket 5 contacts the ground to play a supporting and protective role. The anti-roll bracket 5 contacts the ground to form a support point that effectively prevents the vehicle from tilting further. The immediate supporting role greatly improves the driving stability of the three-wheeled sweeper under complex road conditions. When rollover occurs, the anti-roll bracket 5 can share the weight and impact force of the vehicle, thereby reducing the damage to the vehicle itself and the operator, allowing the operator to focus more on driving operations and thus improve work efficiency. On slopes and complex road conditions, the three-wheeled sweeper can maintain stable driving, which means that the operator can complete the cleaning operation more efficiently. The supporting role of the anti-roll bracket 5 enables the vehicle to continue working under these harsh conditions without interrupting the operation due to tilting. During the collision, the anti-collision large round tube 3 may be subjected to excessive impact force, causing it to deform or be damaged. When operating on a slope, the three-wheeled sweeper is prone to tilt due to gravity. At this time, the anti-roll bracket 5 can play a key role in ensuring the stable operation of the vehicle. When operating on a road with complex road conditions, the three-wheeled sweeper is also prone to tilting when encountering obstacles such as potholes and bumps. The existence of the anti-roll bracket 5 can greatly reduce this risk. Regular inspection and maintenance should be carried out on it, including checking the wear of the bracket, the tightness of the connection parts, etc. During operation, the operator should be familiar with the performance and operating procedures of the three-wheeled sweeper, especially when encountering slopes and complex road conditions, and should operate with caution to avoid the vehicle from tilting.

[0028] See also Figure 2 , Figure 3 and Figure 5 , a multifunctional anti-collision and anti-rollover protection mechanism for a sweeper; The utility model comprises a three-wheel sweeping machine body 1, a side panel connecting plate 2 and a boarding pedal 4. Two sets of side panel connecting plates 2 are symmetrically mounted on the chassis of the three-wheel sweeping machine body 1 by bolts. A bottom docking groove 7 is provided through the center position of the outer side of the side panel connecting plate 2. A chassis threaded interface 8 is provided through the front side of the side panel connecting plate 2. The boarding pedal 4 is symmetrically mounted on the outer end of the anti-collision large round tube 3. A friction anti-slip strip 10 is installed on the top of the boarding pedal 4. The side panel connecting plate 2 is docked with the docking piece of the three-wheel sweeping machine body 1 through the docking groove 7 at the bottom of the machine. The bolts penetrate the chassis threaded interface 8 to firmly install the side panel connecting plate 2 at the bottom of the three-wheel sweeping machine body 1. The boarding foot pedal 4 cooperates with the three-wheel sweeping machine body 1 to make it more convenient for the operator to get on and off the vehicle through the boarding foot pedal 4. The friction anti-slip strip 10 increases the friction between the soles of the operator's feet and the boarding foot pedal 4, allowing the operator to get on and off the vehicle safely.

[0029] See also Figure 2 , Figure 3 , Figure 4 and Figure 6 , a multifunctional anti-collision and anti-rollover protection mechanism for a sweeper; It includes an anti-roll bracket 5, a boarding footboard 4 and a reinforcing support rod 16. The outer end of the anti-roll bracket 5 is installed with a hinge seat 15, and the inner side of the hinge seat 15 is rotatably installed with a reinforcing support rod 16. The bottom of the boarding footboard 4 is provided with a driving bottom groove 11, and a dragging seat 13 is movably installed on the inner side of the driving bottom groove 11, and the bottom end of the dragging seat 13 is hinged to the top of the reinforcing support rod 16. A locking groove 14 is provided on the outer side of the dragging seat 13, and horizontal limiting slide grooves 12 are symmetrically provided on the inner wall of the driving bottom groove 11, and the outer end of the dragging seat 13 slides on the inner side of the horizontal limiting slide groove 12. A plug-in limiting opening 17 is provided on the outer end of the boarding footboard 4, and the plug-in limiting opening 17 is connected with the driving bottom groove 11. A locking stud 18 is connected to the inner side of the plug-in limiting opening 17 through a thread, and the output end of the locking stud 18 matches the locking groove 14. The strengthening support rod 16 is a strengthening structure added to the key part of the anti-roll bracket 5. The strengthening measures further improve the bearing capacity of the anti-roll bracket 5 and reduce the possibility of deformation. The combined design of the strengthening support rod 16 and the boarding foot pedal 4 makes the three-wheeled sweeper more stable and reliable on slopes and complex road conditions. The strengthening support rod 16 supports the deformation of the anti-roll bracket 5 when the roll protection component is working through the boarding foot pedal 4, effectively reducing the deformation of the anti-roll bracket 5 when it is subjected to the roll moment, so that the roll protection component can more stably bear the tipping force when the three-wheeled sweeper tilts. The strengthening support rod 16 improves the bearing capacity of the roll protection component so that the roll protection component can withstand more impacts during the roll. The strengthening support rod 16 effectively supports the anti-roll bracket 5, reducing its deformation and wear during the roll process, and extending the service life of the roll protection component. After long-term use, the supporting angle of the anti-roll bracket 5 will change. The position of the drag seat 13 in the driving bottom groove 11 is adjusted to change the top supporting angle of the reinforcing support rod 16. The reinforcing support rod 16 is fine-tuned along with the supporting angle of the anti-roll bracket 5 to extend the service life of the roll protection. After the adjustment is completed, the locking stud 18 passes through the inner side of the plug-in limit opening 17 to achieve the limiting fixation of the drag seat 13, thereby ensuring the stability of the reinforcing support rod 16 when in use.

[0030] See also Figure 3 , Figure 7 and Figure 8 , a multifunctional anti-collision and anti-rollover protection mechanism for a sweeper; It includes an anti-roll bracket 5, a wear-resistant chrome cast iron frame 6 and a telescopic arc frame 20. The anti-roll bracket 5 is installed with the wear-resistant chrome cast iron frame 6 at the bottom end. The inner wall of the wear-resistant chrome cast iron frame 6 is provided with an expansion slide groove 19. The inner side of the wear-resistant chrome cast iron frame 6 is movably installed with the telescopic arc frame 20, and the outer end of the telescopic arc frame 20 slides on the inner side of the expansion slide groove 19. A damper 21 is installed on the inner side of the wear-resistant chrome cast iron frame 6. A pressure-resistant spring 22 is installed on the outer side of the damper 21, and the outer end of the pressure-resistant spring 22 is connected to the inner side of the telescopic arc frame 20. When the roll protection assembly is working, the chromium carbide composite material pad 25 contacts the ground to make the telescopic arc frame 20 slide in the wear-resistant chromium cast iron frame 6, and the expansion slide groove 19 ensures the stability of the telescopic arc frame 20 when moving. The damper 21 and the pressure-resistant spring 22 buffer the extrusion force to enhance the wear resistance and impact resistance. The sliding of the telescopic arc frame 20 in the wear-resistant chromium cast iron frame 6 enables the anti-roll bracket 5 to adjust its position more flexibly when subjected to the roll moment, forming a more stable support point with the ground, thereby improving the response speed of the roll protection assembly and making the vehicle The vehicle can transition more smoothly during rollover, reducing the impact on the vehicle. The damper 21 can absorb and consume vibration energy, effectively buffer the extrusion force generated during rollover, help reduce the shaking and impact of the vehicle during rollover, and improve the stability and safety of the vehicle. The pressure-resistant spring 22 can deform when under pressure, thereby absorbing and dispersing the impact force. The wear-resistant chromium cast iron frame 6 has not only high hardness but also good wear resistance, and can effectively support the stability of the telescopic arc frame 20 during the sliding process, further improving the durability of the rollover protection component. The stable contact between the anti-roll bracket 5 and the ground, the wear resistance and impact resistance of the chromium carbide composite pad 25, the flexible sliding of the telescopic arc bracket 20, and the buffering effect of the damper 21 and the pressure-resistant spring 22 work together to enable the vehicle to stop more safely when it rolls, reduce the risk of rollover, improve the reliability and durability of the vehicle, and reduce maintenance costs.

The chromium carbide composite material pad 25 in the anti-wear chromium cast iron frame 6 at the bottom of the anti-roll bracket 5 contacts the ground to reduce the wear of the anti-roll bracket 5. The chromium carbide composite material pad 25 effectively reduces the wear when in contact with the ground, and can maintain the integrity of the anti-roll bracket during long-term use. When the roll protection component is subjected to the roll moment, the anti-wear chromium cast iron frame 6 can disperse the stress, reduce the force area of ​​the chromium carbide composite material pad 25, thereby reducing wear, reducing the maintenance difficulty and time, and improving the maintenance efficiency, which helps to reduce the downtime caused by damage to the roll protection component. The chromium carbide composite material pad 25 can be easily disassembled and replaced by bonding it to the adhesive fixing pad 24 through the bonding inner layer 26, thereby reducing the failure rate of the roll protection component and improving the safety and reliability of the sweeper; The chromium carbide composite material pad 25 has extremely high wear resistance and impact resistance, and can effectively reduce the wear of the anti-roll bracket 5 when it contacts the ground, thereby extending its service life. At the same time, its good impact resistance can also provide better protection when the vehicle rolls.
