Detailed Implementation

[0030] 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.

[0031] Example: Reference Figures 1-7 The present invention relates to a special prefabricated road splicing device for cement concrete, comprising a curbstone 1 and a road splicing device 2 installed on the surface of the curbstone 1.

[0032] The road splicing device 2 includes a first frame 21, a supporting top wheel 22, a driving side wheel 23, a lithium battery 24, an opening slot 25, an electric drive assembly 26, a handrail 27, a controller 28, a connecting mechanism 29, and a fixing mechanism 210.

One end of the electric drive assembly 26 is connected to one end of the drive side wheel 23, and the other end extends through the outside of the first frame 21 and is connected to one end of the fixing mechanism 210.

[0033] As a preferred embodiment of this example, Figures 1-7 As shown, the drive wheel 23 includes a rotating shaft 231 and a drive wheel 232. The rotating shaft 231 is rotatably connected to the inner side wall of the first frame 21. The drive wheel 232 is symmetrically fixedly connected to the outer surface of the rotating shaft 231. One end of the rotating shaft 231 passes through the interior of the opening slot 25 and is connected to one end of the electric drive assembly 26. The drive wheel 232 is in contact with the side of the curbstone 1.

[0034] In this embodiment, the structure and connection relationship of the drive side wheel 23 are further explained. The drive side wheel 23 is set to facilitate the movement of the first frame 21 while improving its running stability, and the effect is good.

[0035] As a preferred embodiment of this example, Figures 1-7 As shown, a fast charging interface is provided on the outer surface of the first frame 21 at a position corresponding to the lithium battery 24, and a charging protection circuit is provided between the fast charging interface and the lithium battery 24.

[0036] In this embodiment, a fast charging interface is provided to improve charging efficiency, and a charging protection circuit is provided to protect the lithium battery 24, resulting in better performance.

[0037] As a preferred embodiment of this example, Figures 1-7As shown, the electric drive assembly 26 includes a dual-axis motor 31, an encoder 32, a rotating sleeve 33, a side bevel gear 34, a one-way transmission 35, a drive bevel gear 36, a side transmission rod 37, a synchronous sprocket 38, and a synchronous chain belt 39. The dual-axis motor 31 is bolted to the inner wall of the opening slot 25, and the encoder 32 is bolted to the surface of the dual-axis motor 31. Both the dual-axis motor 31 and the encoder 32 are electrically connected to the controller 28. The rotating sleeve 33 and the side bevel gear 34 are rotatably connected to the inner wall of the opening slot 25 and located outside the dual-axis motor 31, respectively. One end of the rotating sleeve 33 and one end of the side bevel gear 34 are connected to the output end of the dual-axis motor 31 through the one-way transmission 35. One end of the drive bevel gear 33 extends through the outside of the first frame 21 and is connected to one end of the fixing mechanism 210. The drive bevel gear 36 is rotatably connected to the inner wall of the opening slot 25 and located on one side of the side bevel gear 34. The drive bevel gear 36 and the side bevel gear 34 are meshed. The side transmission rod 37 is symmetrically rotatably connected to the inner wall of the opening slot 25 and located outside the drive bevel gear 36. The side transmission rod 37 is respectively positioned corresponding to the drive bevel gear 36 and the rotating shaft 231. One end of the side transmission rod 37 is fixedly connected to the end of the rotating shaft 231 that extends into the opening slot 25. Synchronous sprockets 38 are provided at corresponding positions on the surface of the central shaft of the drive bevel gear 36 and the surface of the side transmission rod 37 and are connected by a synchronous chain belt 39.

[0038] In this embodiment, the structure and connection relationship of the electric drive assembly 26 are further described. The electric drive assembly 26 can not only drive the drive side wheel 23 to rotate, realizing the movement of the first frame 21, but also drive the fixing mechanism 210 to operate, realizing the correction and clamping of the position of the adjacent set of curb stones 1. The effect is good. In use, the controller 28 controls the dual-axis motor 31 to be powered on and run. The dual-axis motor 31 rotates forward and drives the side bevel gear 34 to rotate synchronously through the one-way transmission 35 on the right side. At this time, the rotating sleeve 33 is in a non-rotating state, and the side bevel gear 34 rotates synchronously with the belt. The drive bevel gear 36 rotates, and the rotation of the drive bevel gear 36 drives the side transmission rod 37 to rotate synchronously through the cooperation of the synchronous sprocket 38 and the synchronous chain belt 39. The rotation of the side transmission rod 37 synchronously drives the rotating shaft 231 to rotate, and the rotation of the rotating shaft 231 synchronously drives the drive wheel 232 to rotate. The rotation of the drive wheel 232 synchronously drives the first sleeve frame 21 to move. The dual-axis motor 31 reverses and synchronously drives the rotating sleeve 33 to rotate through the one-way transmission 35 on the left. At this time, the side bevel gear 34 is not rotating. The rotation of the rotating sleeve 33 synchronously links the cross connecting rod 511 to rotate, resulting in good performance.

[0039] As a preferred embodiment of this example, Figures 1-7As shown, the two sets of one-way transmission devices 35 have opposite transmission directions. When the dual-axis motor 31 rotates forward, the dual-axis motor 31 drives the side bevel gear 34 to rotate synchronously through the one-way transmission device 35 on the right side. At this time, the rotating sleeve 33 is in a non-rotating state. When the dual-axis motor 31 rotates in reverse, the dual-axis motor 31 drives the rotating sleeve 33 to rotate synchronously through the one-way transmission device 35 on the left side. At this time, the side bevel gear 34 is in a non-rotating state.

[0040] In this embodiment, the operating state of the one-way drive 35 is further described.

[0041] As a preferred embodiment of this example, Figures 1-7 As shown, the one-way transmission device 35 includes a drive disk 351, a pawl 352, a first spring 353, a linkage disk 354, and internal teeth 355. The drive disk 351 is fixedly connected to the inner wall of the output end of the dual-axis motor 31. A groove is provided on the surface of the drive disk 351. One end of the pawl 352 is rotatably connected to the inner wall of the groove, and the other end is fixedly connected to the inner wall of the groove with the first spring 353. The linkage disk 354 is fixedly connected to the inner wall of the rotating sleeve 33 and the side bevel gear 34 respectively. The linkage disk 354 is sleeved on the outside of the drive disk 351. Internal teeth 355 are provided at the corresponding positions of the inner wall of the linkage disk 354 and the pawl 352. One end of the pawl 352 is engaged with the internal teeth 355.

[0042] In this embodiment, the structure and connection relationship of the one-way drive 35 are further explained.

[0043] As a preferred embodiment of this example, Figures 1-7 As shown, the connecting mechanism 29 includes a first mounting base 41, an electric telescopic rod 42, a second mounting base 43, a transverse guide rod 44, and a side connecting seat 45. The first mounting base 41 is symmetrically fixedly connected to the outer side of the first sleeve frame 21. The electric telescopic rod 42 is fixedly connected to the inner wall of the first mounting base 41. The second mounting base 43 is symmetrically fixedly connected to the outer side of the first sleeve frame 21 and located outside the first mounting base 41. The transverse guide rods 44 are all slidably connected to the inner wall of the second mounting base 43. The end surface of the electric telescopic rod 42 away from the inner wall of the first mounting base 41 and the end surface of the transverse guide rod 44 away from the inner wall of the second mounting base 43 are both fixedly connected to the side connecting seat 45. One end of the side connecting seat 45 is fixedly connected to the surface of the fixing mechanism 210. The electric telescopic rod 42 is electrically connected to the controller 28.

[0044] In this embodiment, the electric telescopic pole 42 is equipped with a motor overload detection device, which is electrically connected to the controller 28. The motor overload detection device includes a current detector and a temperature detector. After the two sets of curb stones 1 are attached, the motor on the electric telescopic pole 42 will continue to run, which will cause it to stall, resulting in a sharp increase in current and temperature. When the current detector and the temperature detector detect that the current value and temperature value exceed the set range, they will send the data signal to the controller 28, and the controller 28 will control the electric telescopic pole 42 to stop running.

[0045] In this embodiment, the structure and connection relationship of the connecting mechanism 29 are further explained. The connecting mechanism 29 is set to facilitate the movement of the adjacent set of curb stones 1 towards the first set of curb stones 1 to realize the splicing operation. The effect is good. In use, the controller 28 controls the electric telescopic rod 42 to reset. The reset of the electric telescopic rod 42 simultaneously drives the side connecting seat 45 and the fixing mechanism 210 to reset. The reset of the fixing mechanism 210 simultaneously drives the adjacent set of curb stones 1 to move towards the first set of curb stones 1 until the surfaces of the two sets of curb stones 1 are in contact. The effect is good. The motor overload detection device can effectively prevent motor overload and can also be used as a detection device to detect whether the surfaces of the two sets of curb stones 1 are in contact. The effect is good.

[0046] As a preferred embodiment of this example, Figures 1-7As shown, the fixing mechanism 210 includes a fixing sleeve 51, a top pressing mechanism 52, a side fixing plate seat 53, a drive gear 54, a first reciprocating lead screw 55, a second reciprocating lead screw 56, a toothed slide seat 57, a drive toothed roller 58, a connecting sprocket 59, a connecting chain belt 510, and a cross connecting rod 511. The fixing sleeve 51 is fixedly connected to the surface of the side connecting seat 45 and sleeved on the outside of an adjacent set of curb stones 1. The top pressing mechanism 52 is installed on the inner top wall of the fixing sleeve 51. The side fixing plate seat 53 is symmetrically slidably connected to the inner side wall of the fixing sleeve 51. The drive gear 54 is rotatably connected to the outer side of the fixing sleeve 51 and corresponds to the position of the side fixing plate seat 53. The first reciprocating lead screw 55 is fixedly connected to the inner wall of the drive gear 54, and one end of the first reciprocating lead screw 55 penetrates into the fixing sleeve 51. The second reciprocating screw 56 is rotatably connected to the inner wall of the side fixed plate seat 53. The top of the fixed sleeve 51 has an installation groove. The second reciprocating screw 56 is rotatably connected to the inner wall of the installation groove. The toothed slide 57 is threaded to the outer surface of the second reciprocating screw 56 and slidably connected to the inner wall of the installation groove. The drive toothed roller 58 is rotatably connected to the top of the fixed sleeve 51 and meshes with the teeth on the top of the toothed slide 57. Both ends of the drive toothed roller 58 extend out of the fixed sleeve 51 and are fixedly connected to the connecting sprocket 59. The connecting sprocket 59 corresponds to the position of the drive gear 54 and is connected to the connecting chain belt 510. One end of the second reciprocating screw 56 extends out of the fixed sleeve 51 and is fixedly connected to the cross connecting rod 511. One end of the cross connecting rod 511 is located inside the rotating sleeve 33 and is slidably connected to the inner wall of the rotating sleeve 33.

[0047] In this embodiment, when the toothed slide 57 moves to the end of the reciprocating guide groove on the second reciprocating screw 56, the outer surface of the side fixing plate 53 contacts the outer surface of the adjacent set of curb stones 1. When the toothed slide 57 resets and moves to the other end of the reciprocating guide groove on the second reciprocating screw 56, the outer surface of the side fixing plate 53 is on the same plane as the inner side wall of the fixing sleeve 51.

[0048] In this embodiment, the structure and connection relationship of the fixing mechanism 210 are further explained. The fixing mechanism 210 is set to facilitate the correction of the position of adjacent sets of curb stones 1, and at the same time, it can clamp and fix them, which facilitates subsequent splicing operations and has good performance. In use, the rotation of the cross connecting rod 511 synchronously drives the second reciprocating screw 56 to rotate. The rotation of the second reciprocating screw 56 synchronously drives the toothed slide 57 to move towards the top pressing mechanism 52. The movement of the toothed slide 57 synchronously squeezes one end of the top pressing mechanism 52 to descend and meet the top of the adjacent set of curb stones 1. When the parts are in contact, the toothed slide 57 moves synchronously, driving the drive roller 58 and the connecting sprocket 59 to rotate. The rotation of the connecting sprocket 59 synchronously drives the connecting chain belt 510 to drive the drive gear 54 to rotate. The rotation of the drive gear 54 synchronously drives the first reciprocating screw 55 to rotate. The rotation of the first reciprocating screw 55 synchronously drives the side fixing plate 53 to reciprocate along the outer surface of the first reciprocating screw 55 and the inner wall of the fixing sleeve 51. The reciprocating movement of the side fixing plate 53 realizes the fixing and loosening of the outer side of the adjacent set of curb stones 1, which has a good effect.

[0049] As a preferred embodiment of this example, Figures 1-7 As shown, the top pressing mechanism 52 includes a central connecting rod 61, a second spring 62, a trapezoidal pressing block 63, a fixed pressing plate 64, and a vertical guide rod 65. The central connecting rod 61 is slidably connected to the inner wall of the fixed sleeve 51 and the second spring 62 is fixedly connected between the central connecting rod 61 and the inner wall of the fixed sleeve 51. One end of the central connecting rod 61 passes through the inside of the mounting groove and is fixedly connected to the trapezoidal pressing block 63, while the other end passes through the bottom of the fixed sleeve 51 and is fixedly connected to the fixed pressing plate 64. The trapezoidal pressing block 63 is located on one side of the bottom of the toothed slide seat 57. The fixed pressing plate 64 corresponds to the top position of the adjacent set of curb stones 1. The vertical guide rods 65 are symmetrically fixedly connected to the top of the fixed pressing plate 64. One end of each vertical guide rod 65 passes through the inside of the fixed sleeve 51 and is slidably connected to the inner wall of the fixed sleeve 51.

[0050] In this embodiment, the bottom of the trapezoidal pressure block 63 is provided with a trapezoidal portion that matches the outer dimensions of the trapezoidal pressure block 63.

[0051] In this embodiment, the structure and connection relationship of the top pressing mechanism 52 are further explained. The top pressing mechanism 52 is set to facilitate the limiting of the top of the adjacent set of curb stones 1, and the use effect is good. When in use, the toothed slide seat 57 moves synchronously to squeeze the trapezoidal pressure block 63 to move downward. The trapezoidal pressure block 63 moves downward and synchronously drives the middle connecting rod 61, the fixed pressure plate 64 and the vertical guide rod 65 to move downward and stretch the second spring 62. The second spring 62 facilitates the reset of the trapezoidal pressure block 63 and the fixed pressure plate 64. The vertical guide rod 65 plays a limiting and guiding role, and also improves its running stability, resulting in good use effect.

[0052] As a preferred embodiment of this example, Figures 1-7 As shown, limit posts 100 are provided at the corresponding positions on the outer end face of the fixed sleeve 51 and the outer end face of the first sleeve 21, and counterweights 200 are symmetrically arranged inside the first sleeve 21.

[0053] In this embodiment, a limiting post 100 is set to maintain a set distance between the fixed sleeve 51 and the first sleeve 21, and a counterweight 200 is set to improve the movement stability of the first sleeve 21, resulting in good performance.

[0054] Working principle of the invention: In use, the device is fitted onto the outside of the first set of curb stones 1. Then, the dual-axis motor 31 is reversed by the controller 28. The reverse rotation of the dual-axis motor 31 synchronously drives the rotating sleeve 33 to rotate through the one-way transmission 35 on the left. At this time, the side bevel gear 34 is not rotating. The rotation of the rotating sleeve 33 synchronously drives the cross connecting rod 511 to rotate. The rotation of the cross connecting rod 511 synchronously drives the second reciprocating screw 56 to rotate. The rotation of the second reciprocating screw 56 synchronously drives the toothed slide 57 to move towards the top pressing mechanism 52. The movement of the toothed slide 57 synchronously presses one end of the top pressing mechanism 52 down and contacts the top of the adjacent set of curb stones 1. At the same time, the movement of the toothed slide 57 synchronously drives the drive roller 58 to rotate and... The connecting sprocket 59 rotates, which in turn drives the connecting chain belt 510 to rotate the drive gear 54. The drive gear 54 then rotates, which in turn drives the first reciprocating screw 55. The rotation of the first reciprocating screw 55 in turn drives the side fixing plate 53 to reciprocate along the outer surface of the first reciprocating screw 55 and the inner wall of the fixing sleeve 51. The reciprocating movement of the side fixing plate 53 achieves the fixing and loosening of the outer side of the adjacent set of curb stones 1, which has a good effect. After the side fixing plate 53 extends outward along the outer surface of the first reciprocating screw 55 and the inner wall of the fixing sleeve 51 and clamps and fixes the outer side of the adjacent set of curb stones 1, the controller 28 controls the electric telescopic rod 42 to reset. The reset of the electric telescopic rod 42 in turn drives the side connecting seat. 45 and the fixing mechanism 210 reset. The reset of the fixing mechanism 210 synchronously drives the adjacent set of curb stones 1 to move towards the first set of curb stones 1 until the surfaces of the two sets of curb stones 1 are in contact. The effect is good. The motor overload detection device can effectively prevent motor overload and can also be used as a detection device to detect whether the surfaces of the two sets of curb stones 1 are in contact. The motor overload detection device includes a current detector and a temperature detector. After the two sets of curb stones 1 are in contact, if the motor on the electric telescopic pole 42 continues to run, it will cause the motor to stall, resulting in a sharp increase in current and temperature. When the current detector and temperature detector detect that the current value and temperature value exceed the set range value, they send the data signal to the controller 28, and the controller 28 controls the electric telescopic pole 42 to stop running. The system works well. After the surfaces of the two sets of curb stones 1 are in contact, the controller 28 controls the dual-axis motor 31 to reverse and reset the toothed slide block 57 and the side fixed plate 53, thus releasing the adjacent set of curb stones 1. Then, the controller 28 controls the dual-axis motor 31 to rotate forward. The forward rotation of the dual-axis motor 31 synchronously drives the side bevel gear 34 to rotate through the one-way transmission 35 on the right side. At this time, the rotating sleeve 33 is not rotating. The rotation of the side bevel gear 34 synchronously drives the drive bevel gear 36 to rotate. The rotation of the drive bevel gear 36 synchronously drives the side transmission rod 37 to rotate through the cooperation of the synchronous sprocket 38 and the synchronous chain belt 39. The rotation of the side transmission rod 37 synchronously drives the rotating shaft 231 to rotate. The rotation of the rotating shaft 231 synchronously drives the drive wheel 232 to rotate.The rotation of drive wheel 232 synchronously drives the movement of the first frame 21, resulting in good performance.
