Description

Technical Field

[0001] The present invention relates to the technical field of track laying, and in particular to an integrated stadium track laying device and method. Background Art

[0002] Most stadium tracks are plastic tracks, which are made of materials such as polyurethane rubber. They have certain elasticity and color, and have certain UV resistance and aging resistance. They are internationally recognized as the best all-weather outdoor sports ground material. During construction, the plastic track is laid on asphalt or cement foundation, and the basic method is roughly the same as road construction. The surface flatness of the foundation is required to be high to ensure that the thickness of the plastic surface layer is consistent and the elasticity is uniform.

[0003] However, there are strict requirements for laying the track in the stadium. In the existing laying process, the mixed materials are usually piled up in the walking path of the laying equipment in advance, and the materials need to be spread out manually for a second time. In the manual spreading process, the initial paving cannot be uniform, resulting in excessive accumulation of materials on the inside of the turn relative to the outside of the turn when paving the curve, resulting in excessive material accumulation when pressed by the leveling mechanism, and rebound differences after the materials solidify. This leads to uneven force during the later use of the runway, resulting in cracks in the runway.

[0004] For example, a Chinese patent with application number 201910792882.2 discloses a plastic track paver, including a machine body, tracks arranged on both sides of the machine body, and a scraper arranged on the machine body. Both ends of the machine body are detachably connected with a flattening device, and the flattening device includes a flattening box arranged on the machine body and having an opening on the side close to the ground, two flattening rollers rotatably connected to the flattening box at intervals and rotating in opposite directions, and flattening wheels evenly spaced on the flattening rollers and used to abut against the ground. The flattening wheels on the two flattening rollers are staggered, and a driving assembly for driving the flattening rollers to rotate is provided on the machine body. The invention has the following effects: the two flattening rollers rotate in opposite directions, and the flattening wheels on both sides rotate away from each other in the tangential direction on the side close to the ground. When the flattening wheels come into contact with the plastic particles, the accumulated surplus materials will be pushed flat to the paving belts on both sides, saving time and improving construction efficiency. Although the invention will push the accumulated surplus materials to the paving belts on both sides when the flattening wheels come into contact with the plastic particles, when paving curves, the flattening wheels will further compact the plastic particles that are in contact, resulting in a large difference in the compactness of the plastic particles when paving the joints and the curves, resulting in uneven force and cracking in later use.

[0005] To this end, the present invention proposes an integrated stadium track paving device and method to solve the above-mentioned problems. Summary of the invention

[0020] A method for laying a stadium runway integrated laying device comprises the following steps:

[0021] S1. Move the main body of the equipment to the area to be laid;

[0022] S2. The plurality of dividing plates in the unloading section are adjusted by the adjusting section;

[0023] S3. Place the mixed materials into the discharge bin;

[0024] S4. Start the first motor to drive the unloading part to perform preliminary laying;

[0025] S5. Start the second motor, which rotates back and forth. The gear and the rack mesh with each other, and the rack drives the leveling block to slide back and forth at the bottom of the leveling frame to flatten and lay the initially laid material again.

[0026] Technical effects and advantages of the present invention:

[0027] 1. The rotating part rotates so that the plastic particles between the two dividing plates in the discharge bin are evenly discharged through the discharge port, and the fine particles in the plastic particles are also evenly discharged for preliminary laying. While the material is evenly discharged, the dividing plate extending from the bottom of the discharge bin preliminarily blocks and flattens the discharged plastic particles.

[0028] 2. The gear reciprocates to drive the rack to slide back and forth in the slide groove provided in the leveling frame. The rack reciprocates in the slide groove and drives the leveling block to slide at the bottom of the leveling frame. The rack drives the leveling block to slide back and forth at the bottom of the leveling frame to flatten and lay the initially laid plastic particles again.

[0029] 3. The rotation deviation of the rotating parts located on the inner and outer sides of the curve causes a deviation, so that when the plastic particles located on the inner side of the curve are laid, the rotating parts located on the inner side of the curve rotate, which reduces the amount of plastic particles located between the two dividing plates in the discharge bin that are uniformly discharged through the discharge port, resulting in a difference in the amount of plastic particles discharged through the corresponding dividing plates between the plastic particles on the inner side of the curve and the plastic particles on the outer side of the curve, thereby preventing excessive accumulation of plastic particles on the inner side of the curve, and further making the plastic particles initially laid on the curve more evenly spread out by the leveling block again, thereby preventing the runway from cracking due to uneven force during later use.

[0030] 4. The two pawls are rotated by rotating the ratchet wheel, and the two pawls respectively drive the corresponding transmission blocks to rotate. When the transmission blocks rotate, they drive the rotating rod to rotate in the placement groove opened at the bottom of the rotating part. When the rotating rod rotates, it drives multiple fixed sleeves to rotate. When the fixed sleeves rotate, it drives multiple limit columns to rotate synchronously. When the fixed sleeves rotate, multiple dividing plates are offset around the limit columns through the clamping grooves. When the multiple dividing plates are offset, they slide in the corresponding guide long holes. When the dividing plates slide in the guide long holes, they continue to move away from the inner wall of the discharge bin, so that the gap between the dividing plates and the discharge bin is continuously expanded. The thickness of the initially laid plastic particles is adjusted through the gap between the dividing plates and the discharge bin, so that the leveling block further levels the initially laid plastic particles to prevent waves from appearing after the plastic particles are laid, which affects the later construction.

DETAILED DESCRIPTION

[0044] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention. Example 1

[0045] It is found during use that, when laying in a straight line, the traditional laying method is to pour the stirred and mixed plastic particles directly into the area to be laid, and the poured plastic particles are piled in a cone shape, and then the piled plastic particles are manually flattened by tools. In the process of flattening the plastic particles, skilled manual operation is required. When the flattened thickness is uneven, the paving surface will appear uneven. Although the uneven plastic particle paving surface can be scraped flat by the existing scraper, due to the uneven size of the plastic particles themselves, the fine granular materials in the plastic particles cannot be spread out by traditional manual or scraper methods, resulting in larger gaps after the plastic runway is formed. After the plastic runway is solidified and formed, it will crack when the larger gaps are stepped on, resulting in a reduced service life of the plastic runway. This embodiment is specially invented to solve the above problems.

[0046] See also Figure 1 and Figure 2 As shown, an integrated stadium track paving device according to an embodiment of the present invention comprises a device body 1, crawlers 101 arranged on both sides of the device body 1, and a control box 102 for circuit control, wherein the control box 102 is also provided with a controller, wherein the controller is the prior art and will not be described in detail herein, and further comprises a leveling part 2, a material discharging part 3, and an adjusting part 4, in combination with Figure 3 The leveling part 2 includes a leveling frame 21 movably connected to one side of the equipment body 1 , and a leveling block 22 is slidably connected to the bottom of the leveling frame 21 .

[0047] See also Figure 3 and Figure 4 As shown, the unloading part 3 includes two unloading bins 31 fixedly connected to the inner side of the equipment body 1, and the inner bottoms of the two unloading bins 31 are rotatably connected to a rotating member 32, combined with Figure 7 and Fig.12 Each rotating member 32 is provided with a plurality of guide long holes 321 in the circumferential direction, and a placement groove is provided in the inner bottom of each rotating member 32. A rotating rod 33 is rotatably connected in the placement groove of each rotating member 32. A spring for squeezing the rotating rod 33 is provided in each placement groove, and a plurality of fixing sleeves 34 are fixedly connected to the outer wall of each rotating rod 33. Fig. 9 and Fig.10A dividing plate 35 is inserted into each guide long hole 321, and each dividing plate 35 is provided with a plurality of avoidance grooves 351 adapted to the fixing sleeve 34. The inner side of each avoidance groove 351 is provided with two relatively arranged clamping grooves 352. Each fixing sleeve 34 is provided with a plurality of placement holes, and each placement hole is provided with a first elastic member 341 and two limiting columns 342, wherein the first elastic member 341 is a spring.

[0048] See also Figure 8 As shown, both ends of each first elastic member 341 are connected to the ends of the two limiting columns 342 in the placement hole that are close to each other, and the ends of each two limiting columns 342 extending out of the placement hole are inserted into the corresponding clamping grooves 352.

[0049] See also Figure 4 and Figure 5 As shown, the outer wall of one end of each rotating member 32 away from the fixed member 41 is connected to the first pulley 5 through a key transmission. Figure 3 Two first motors 6 for driving the crawlers 101 on both sides of the equipment body 1 are fixedly connected in the control box 102. It should be noted that each first motor 6 is electrically connected to the controller, and the output ends of the two first motors 6 are connected to the rotating shaft of the matching crawler 101 through a coupling. The output ends of the two first motors 6 are connected to the second pulley 7 through a key transmission, and each second pulley 7 is connected to the matching first pulley 5 through a belt transmission.

[0050] See also Figure 3 As shown, a rack 23 is fixedly connected to the top of the leveling block 22, and a slide groove for sliding and guiding the rack 23 is provided in the leveling frame 21. A second motor 24 is fixedly connected to the inner wall of one end of the leveling frame 21 close to the two discharge bins 31, wherein the second motor 24 is electrically connected to the controller, and the output end of the second motor 24 is connected to the gear 25 through a key transmission. A feeding port is provided at the bottom of each discharge bin 31, and the gear 25 and the rack 23 are meshed with each other. Two clamping blocks 26 are fixedly connected to one side of the leveling frame 21 close to the equipment body 1, and a clamping piece 103 adapted to the two clamping blocks 26 is fixedly connected to one side of the equipment body 1 close to the leveling frame 21, and threaded screws 261 are provided in the two clamping blocks 26. Two support blocks located below the leveling frame 21 are fixedly connected to one side of the equipment body 1 close to the leveling frame 21, and one end of each threaded screw 261 extending out of the clamping block 26 is rotatably clamped in the support block corresponding to the lower part. The outer wall of each threaded screw rod 261 is sleeved with a spring, and both ends of each spring are connected to the top of the corresponding support block and the bottom of the clamping block 26 .

[0051] See also Figure 6 and Figure 7The cam 332 is provided with a second spring 323 which is a spring and is arranged in a compressed state in the locking ring 322. The second spring 323 is a spring and is arranged in a compressed state in the locking ring 322. The purpose of such arrangement is to make the second spring 323 always squeeze the rotating column 36 to prevent the rotating column 36 from loosening in the locking ring 322. The two ends of each second spring 323 are connected to one end of the corresponding rotating column 36 and one end of the rotating member 32. The ends of the two rotating rods 33 which are close to each other are fixedly connected to the transmission block 331. Fig.11 and Fig.12 A connecting groove 361 is formed in each rotating column 36 , and each transmission block 331 is inserted into the corresponding connecting groove 361 .

[0052] When in use, by rotating the two threaded screws 261 at the same time, the two threaded screws 261 make the clamping block 26 slide up and down in the clamping member 103, so as to adjust the height of the leveling block 22 from the paving base surface. After that, the plastic particles that are evenly mixed or prefabricated in advance are placed in the two discharge bins 31, and the two first motors 6 and the second motor 24 are started by the controller. The two first motors 6 rotate and drive the rotating shaft of the crawler 101 to rotate through the coupling. The crawler 101 located on both sides of the equipment body 1 drives the equipment body 1 to move. At the same time, the two first motors 6 rotate and drive the corresponding second pulleys 7 to rotate through the key transmission. The two second pulleys 7 respectively rotate the corresponding first pulleys 5 through the transmission belt. When the first pulley 5 rotates, the rotating member 32 is driven to rotate in the discharge bin 31 through the key transmission. When the rotating member 32 rotates, the locking ring 322 rotates synchronously. When the locking ring 322 rotates synchronously with the rotating member 32, the rotating column 36 rotates together with the rotating column 36, and when the rotating column 36 rotates with the locking ring 322, the transmission block 331 rotates together with the rotating column 36, and when the transmission block 331 rotates, the rotating rod 33 rotates synchronously, and when the rotating rod 33 rotates, the fixed sleeve 34 rotates synchronously. The restriction of the limit column 342 and the guide long hole 321 makes multiple dividing plates 35 rotate synchronously with the rotating member 32. When the rotating member 32 rotates, the plastic particles in the discharge bin 31 are stirred and extruded through the dividing plates 35. The plastic particles between the two dividing plates 35 in the discharge bin 31 are evenly discharged through the discharge port through the rotation of the rotating member 32, and the fine particles in the plastic particles are also evenly discharged for preliminary laying. While the material is evenly discharged, the dividing plate 35 extending from the bottom of the discharge bin 31 initially blocks and flattens the discharged plastic particles.

[0053] At the same time, the second motor 24 reciprocates, and while the second motor 24 reciprocates, it drives the gear 25 to reciprocate through key transmission. While the gear 25 reciprocates, it drives the rack 23 to slide back and forth in the slide groove provided in the leveling frame 21. While the rack 23 slides back and forth in the slide groove, it drives the leveling block 22 to slide at the bottom of the leveling frame 21. The rack 23 drives the leveling block 22 to slide back and forth at the bottom of the leveling frame 21 to flatten and lay the initially laid plastic particles again. Example 2

[0054] On the basis of the above-mentioned embodiment, it is found in actual use that although the plastic particles located between the multiple dividing plates 35 in the discharge bin 31 are evenly discharged through the discharge port by the rotation of the rotating member 32, the fine particles in the plastic particles are also evenly discharged for preliminary paving, and the equipment body 1 is able to perform preliminary paving on the straight paving surface and achieve a uniform paving effect, but when paving the curve, since the plastic particles on the inside of the curve and the plastic particles on the outside of the curve are discharged in the same amount through the multiple dividing plates 35, excessive material accumulation occurs when the leveling block 22 is pressed, and there is a difference in rebound after the material solidifies, resulting in uneven force on the runway during later use, resulting in the problem of cracking of the runway. Further improvements are made on the basis of the above-mentioned embodiment.

[0055] On the basis of the above embodiment, when it is necessary to pave a curve, the rotation speeds of the two first motors 6 are adjusted by the controller, and the controller reduces the rotation speed of the first motor 6 located on the inner side of the curve, and the rotation speed of the first motor 6 located on the outer side of the curve is greater than the rotation speed of the first motor 6 located on the inner side of the curve, and the rotation speed of the first motor 6 located on the outer side of the curve is adapted to the rotation speed of the first motor 6 located on the inner side of the curve, and the rotation speed of the first motor 6 on the inner side of the curve is less than the rotation speed of the first motor 6 located on the outer side of the curve, so that the first motor 6 located on the inner side of the curve rotates slower, and at the same time, the rotation of the first motor 6 located on the inner side of the curve drives the second pulley 7 to rotate through the key transmission. The second pulley 7 located on the inner side of the curve rotates the first pulley 5 through the transmission belt, and the rotating member 32 located on the inner side of the curve rotates while stirring and extruding the plastic particles in the discharge bin 31 located on the inner side of the curve through the dividing plate 35. The rotating member 32 located on the inner side of the curve rotates so that the plastic particles between the two dividing plates 35 in the discharge bin 31 are evenly discharged through the discharge port. At the same time, the first motor 6 located on the outer side of the curve rotates faster than the first motor 6 located on the inner side of the curve. The first motor 6 located on the outer side of the curve rotates through the key transmission to drive the second pulley 7 to rotate. The second pulley 7 located on the outer side of the curve rotates through the key transmission. The transmission belt rotates the first pulley 5, and the rotating member 32 located on the outside of the curve rotates while the plastic particles in the discharge bin 31 located on the outside of the curve are stirred and extruded through the dividing plate 35. The rotating member 32 located on the outside of the curve rotates so that the plastic particles located between the two dividing plates 35 in the discharge bin 31 located on the outside of the curve are uniformly discharged through the discharge port. The first motor 6 located on the inside and outside of the paved curve realizes the speed difference through the controller, and the equipment body 1 is driven to turn through the crawler 101 located on the inside and outside of the curve. At the same time, the rotating member 3 located on the inside and outside of the curve is used to drive the equipment body 1 to turn. 2 has a rotation deviation, so that when the plastic particles located on the inner side of the curve are laid, the rotating member 32 located on the inner side of the curve rotates, which reduces the amount of plastic particles located between the two dividing plates 35 in the discharge bin 31 discharged uniformly through the discharge port, so that the plastic particles on the inner side of the curve and the plastic particles on the outer side of the curve are discharged through the corresponding dividing plates 35. Excessive accumulation of plastic particles on the inner side of the curve is prevented, and the plastic particles initially laid on the curve by the leveling block 22 are further evenly spread again, thereby preventing the runway from cracking due to uneven force during later use. Example 3

[0056] In actual use, it was found that sometimes in order to improve the laying efficiency, the movement of the equipment body 1 would be accelerated. When the movement of the equipment body 1 was accelerated, it was found that the gap between the dividing plate 35 and the discharge bin 31 could not be adjusted according to the actual required thickness, resulting in the need to lay a higher thickness than the standard thickness and when the equipment body 1 moved too fast. The initial laying thickness could not be adjusted, resulting in the leveling block 22 being unable to further level the initially laid plastic particles, resulting in waves after the plastic particles were laid, affecting the later construction.

[0057] See also Figure 4 and Figure 5 As shown, the adjusting part 4 includes a fixing member 41 fixedly connected between the two discharge bins 31, combined with Figure 7 , Fig.11 and Fig.12 A ratchet 42 is rotatably connected in the fixing member 41, and a pawl 37 is provided at one end of each transmission block 331 close to each other. The outer wall of each pawl 37 cooperates with the inner wall of the ratchet 42, and an adjusting column 421 is fixedly connected to the outer wall of the ratchet 42. A guide groove 411 for sliding and limiting the adjusting column 421 is provided in the fixing member 41, and a fastening sleeve 43 is threadedly connected to the outer wall of the end of the adjusting column 421 away from the ratchet 42, and an adjusting groove 431 is provided at the end of the fastening sleeve 43 away from the adjusting column 421. A clamping block 44 is provided on the outer wall of the adjusting column 421, and two ends of the clamping block 44 are respectively connected to one end of the fastening sleeve 43 close to the adjusting column 421 and the outer wall of the fixing member 41, and an anti-slip pad is provided at the connection between the clamping block 44 and the fixing member 41.

[0058] When used on the basis of the above embodiment, when it is necessary to adjust the thickness of the plastic particles laid, the adjusting column 421 is moved in the guide groove 411 toward the fixing member 41. The adjusting column 421 drives the ratchet 42 to rotate in the fixing member 41 while moving. The ratchet 42 drives the two pawls 37 to rotate while rotating. The two pawls 37 drive the corresponding transmission blocks 331 to rotate while rotating. The transmission block 331 drives the rotating column 36 to rotate in the locking ring 322 while rotating. The end face of the rotating column 36 continuously approaches one end of the rotating member 32 while rotating. The rotating column 36 continuously squeezes the second elastic member 323 while approaching one end of the rotating member 32. The transmission block 331 drives the rotating rod 33 to rotate in the placement groove provided at the bottom of the rotating member 32 while rotating. The rotating rod 33 drives the spring while rotating in the placement groove. The rotating rod 33 drives the multiple fixing sleeves 34 to rotate while rotating. The fixing sleeve 34 drives the multiple limiting columns 342 to rotate simultaneously while rotating. The fixing sleeve 34 rotates step by step, and the plurality of dividing plates 35 are offset around the limiting column 342 through the clamping groove 352 while the fixing sleeve 34 rotates. The plurality of dividing plates 35 are offset while sliding in the corresponding guide long holes 321. The dividing plates 35 are continuously away from the inner wall of the discharge bin 31 while sliding in the guide long holes 321, so that the gap between the dividing plates 35 and the discharge bin 31 is continuously expanded. When the corresponding gap is adjusted, the existing tool is used to match the adjusting groove 431 opened by the fastening sleeve 43. The fastening sleeve 43 is closed and rotated clockwise, and the fastening sleeve 43 rotates on the outer wall of the adjusting column 421. While the fastening sleeve 43 rotates, it continuously squeezes the clamping block 44 and the anti-skid pad, so that the clamping block 44 and the anti-skid pad continuously squeeze the fixing piece 41. When the fastening sleeve 43 cannot be applied with a clockwise rotating force, the ratchet 42 rotates clockwise on the outer wall of the adjusting column 421 through the fastening sleeve 43 to squeeze the clamping block 44, so that the ratchet 42 is fixed to the fixing piece 41, thereby preventing the ratchet 42 from loosening.

[0059] When the locking cam 33 is in the unlocking state, the locking cam 332 is in the unlocking state, and the locking cam 333 is in the unlocking state, so that the locking cam 332 is locked. Example 4
