[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] In the current technology, the flatbed conveyor trolleys used in the construction industry are assembled from waste materials on site and pushed by workers on steel rails to transport building materials. However, there are many impurities on the construction site, such as concrete, which can easily fall onto the steel rails made of steel pipes, affecting the transportation of the flatbed conveyor trolley. Therefore, there is an urgent need to solve this problem.

[0028] like Figures 1-7As shown, this is a construction material guide rail type flatbed conveyor trolley. This flatbed conveyor trolley runs on steel rails 100 made from scrap steel pipes at existing construction sites. The flatbed conveyor trolley includes a flatbed conveyor body 1. A cleaning mechanism 2 and a cleaning mechanism 3 are symmetrically arranged on both sides of the head of the flatbed conveyor body 1. Each cleaning mechanism 2 and cleaning mechanism 3 forms a group, and both groups are located directly above the corresponding side rails 100. Both the cleaning mechanism 2 and the cleaning mechanism 3 are in contact with the upper semi-circular surface of the corresponding side rails 100. The bottom of the impurity removal mechanism 2 is also provided with an arc-shaped surface that fits perfectly with the upper half-arc surface of the rail 100. The cleaning mechanism 3 is provided with bristles 33. The bristles 33 adhere to the upper half-arc surface of the rail 100 due to their softness. By setting the impurity removal mechanism 2 and the cleaning mechanism 3, impurities on the rail 100 are cleaned in advance when the flatbed conveyor trolley body 1 moves, so as to avoid affecting the operation of the flatbed conveyor trolley. The impurity removal mechanism 2 cleans stubborn impurities, and the cleaning mechanism 3 cleans non-stubborn impurities and works with the impurity removal mechanism 2 to clean stubborn impurities.

[0029] Further, such as Figures 1-3 As shown, the flatbed conveyor trolley body 1 includes a platform 10, with wheels 12 at the bottom of the platform 10. The wheels 12 are adapted to the rails 100 and can slide on the rails 100. A drive system 13 is provided in the middle of the bottom of the platform 10 to drive the entire flatbed conveyor trolley. Furthermore, a bucket 11 is provided on the top of the platform 10. The bucket 11 is used to place building materials for transportation. The bucket 11 has an elastic bottom plate inside. The elastic bottom plate cushions the material when it is placed and lifts it when it is taken out, making it convenient to use the building materials. At the same time, a controller (not shown) is provided on one side of the top of the platform 10 to control the movement of the servo motor 21.

[0030] Furthermore, a first mounting groove 14 is provided on the side of the vehicle plate 10 near the impurity removal mechanism 2, and a second mounting groove 15 is provided at the front end of the first mounting groove 14. The second mounting groove 15 is connected to the first mounting groove 14. A third mounting groove 16 is provided near the outer side of the second mounting groove 15, and a connecting through hole 17 is provided between the third mounting groove 16 and the outer side of the vehicle plate 10.

[0031] Further, such as Figures 2-5 As shown, the aforementioned impurity removal mechanism 2 includes a servo motor 21 installed in the first mounting slot 14 and a rotating rod 24 installed in the second mounting slot 15. The rotating rod 24 is rotatably mounted on the outer end of the second mounting slot 15 via a rotating shaft. An impact ball 22 is connected to the end of the rotating rod 24 near the servo motor 21. A connecting rope 23 connects the impact ball 22 to the output rod of the servo motor 21. The servo motor 21 can pull the impact ball 22 by winding the connecting rope 23. More details are as follows... Figure 3As shown, a positioning component 25 is provided in the third mounting slot 16. The positioning component 25 is used to position the rotating rod 24 so that it is fixed when it is in a horizontal state. Furthermore, a dirt removal component 26 is provided at the bottom front end of the vehicle plate 10. The dirt removal component 26 is impacted by the impact ball 22 to clean stubborn impurities.

[0032] Detailed structure as follows Figure 3 As shown, the rotating rod 24 has a slot 241 near the top of the rotating end. The slot 241 is inclined and its straight side is close to the rotating shaft. The slot 241 also has a guide surface 242 on the straight side, which is used to guide the positioning component 25 when the rotating rod 24 returns to the horizontal position, so as to facilitate the insertion of the positioning component 25 into the rotating rod 24 for fixing. The positioning component 25 includes a fixing pin 251 that is slidably disposed in the third mounting groove 16. A first spring 252 is provided at the tail of the fixing pin 251 and the bottom of the third mounting groove 16. The tail of the fixing pin 251 is connected to a connecting wire rope 253. The other end of the connecting wire rope 253 is provided through the connecting through hole 17. A guide wheel 254 is provided at the position of the vehicle plate 10 near the connecting through hole 17. The connecting wire rope 253 extends vertically downward around the guide wheel 254 and connects to the impurity removal component 26.

[0033] Further, such as Figure 4 and Figure 5 As shown, the aforementioned impurity removal component 26 includes a connecting plate 261 fixedly connected to the bottom of the vehicle plate 10. A connecting part 264 is provided at the bottom of the connecting plate 261, through which a conical base 265 is connected. Furthermore, a mating groove 262 is formed in the middle of the inner side of the connecting plate 261. The mating groove 262 is adapted to the rotating rod 24 and is larger in size than the rotating rod 24. A through hole 263 is formed in the middle of the connecting plate 261. A guide wheel 254 is provided on both the inner and outer sides of the through hole 263. The outer guide wheel 254 is located above the through hole 263, and the inner guide wheel 254 is located below the through hole 263. It cooperates with the vertically arranged connecting steel wire rope 253 to connect the connecting steel wire rope 254. 3. The tapered base 265 is further guided to the inner end and has a sliding groove 269 inside. The sliding groove 269 is inverted Y-shaped. The connecting part 264 at the bottom of the connecting plate 261 is also inverted Y-shaped. The connecting part 264 is slidably disposed in the sliding groove 269. A second spring 267 is disposed in the sliding groove 269. One end of the second spring 267 is connected to the sliding groove 269 and the other end is connected to the connecting part 264 for rebound. A base plate 266 is disposed at the tail of the tapered base 265. The connecting wire rope 253 guided to the inner end is connected to the base plate 266. A tapered inclined surface 268 is disposed at the top of the tapered base 265. The tapered inclined surface 268 is inclined toward the rail 100.

[0034] In this invention, when the flatbed conveyor trolley encounters stubborn impurities on the rail 100, the stubborn impurities will squeeze the conical base 265, causing the conical base 265 to retract, which in turn drives the base plate 266 to retract. The base plate 266 pulls the connecting wire rope 253, which in turn drives the fixing pin 251 to move upward. The fixing pin 251 leaves the slot 241. Due to gravity, the impact ball 22 and the rotating rod 24 rotate and fall around the axis, impacting the base plate 266 and pushing the conical base 265 to remove the stubborn impurities. Afterward, the controller starts the servo motor 21 to rotate, winding the connecting rope 23 and pulling the impact ball 22 upward until the impact ball 22 and the rotating rod 24 return to the horizontal position. At this time, the fixing pin 251 will insert into the slot 241, fixing the rotating rod 24 again. At the same time, the servo motor 21 reverses to release the connecting rope 23 to the initial stage. Throughout the entire cleaning process, the flatbed conveyor trolley body 1 continues to move.

[0035] Further, such as Figure 1 As shown, the cleaning mechanism 3 includes a connecting rod 31 set on the front side of the car plate 10. The connecting rod 31 is set at an angle downward. At the same time, the bottom end of the connecting rod 31 is connected to a mounting cover 32. The bottom end of the mounting cover 32 is provided with multiple bristles 33 to clean non-stubborn impurities such as dust on the rail 100. At the same time, when encountering stubborn impurities, it covers the stubborn impurities to reduce the splashing caused by impact to clear the impurities and avoid accidental injury to the staff.

[0036] When this invention is working, as Figure 6 and Figure 7As shown, the drive system 13 drives the flatbed conveyor trolley to move on the rail 100. When encountering non-stubborn impurities, the brush 33 of the cleaning mechanism 3 at the front end removes the impurities to avoid affecting the movement of the flatbed conveyor trolley. When encountering stubborn impurities, the flatbed conveyor trolley continues to move, and the stubborn impurities will squeeze the conical base 265, causing the conical base 265 to move backward. The backward movement of the conical base 265 drives the base plate 266 to move backward, and the backward movement of the base plate 266 pulls the connecting wire rope 253. The other end of the connecting wire rope 253 pulls the fixing pin 251 upward. When the fixing pin 251 leaves the slot 241, the impact ball 22 will fall due to its own weight. Due to the connection of the rotating rod 24, the impact ball 22 will rotate and fall, impacting the base plate 266. The base plate 266 is subjected to a moving impact force, which is transmitted to the conical base 265. The conical base 265 impacts and removes stubborn impurities. After the impact, the controller controls the servo motor 21 to wind the connecting rope 23 and pull the impact ball 22 back to its original position. Then, the fixing pin 251 fixes the rotating rod 24, thereby fixing the impact ball 22. After that, the servo motor 21 releases the connecting rope 23 to its original state (i.e., the length sufficient for the impact ball 22 to impact). After the impact, the conical base 265 removes the stubborn impurities. The conical base 265 returns to its initial position due to the second spring 267, the connecting wire rope 253 loosens, and the fixing pin 251 falls. Then, under the pressure of the moving rotating rod 24, it is guided by the guide surface 242 into the slot 241 to complete the fixation.
