DETAILED DESCRIPTION

[0024] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0025] like Figures 1 to 6 As shown, the embodiment of the utility model provides a curbstone transporting device for road construction, which is used to transport the curbstone 100 to the construction site during the road construction process, so as to facilitate the subsequent installation of the curbstone 100.

[0026] Please refer to Figures 1 to 4The curbstone handling device for road construction includes a moving seat 1, a supporting seat 2 is provided on the moving seat 1, a plurality of limiting grooves 21 are provided on the supporting seat 2 at intervals, and the plurality of limiting grooves 21 are arranged in a row on the supporting seat 2, and slide grooves 22 are provided on opposite sides of the limiting groove 21, and the slide grooves 22 located on opposite sides of the same limiting groove 21 are respectively connected with the limiting groove 21, and a plurality of limiting components 3 are also provided on the supporting seat 2, and the limiting components 3 include a wedge block 31 which can be lifted and lowered and is arranged in the limiting groove 21 and a first spring 32 abutting against the wedge block 31, the width of the wedge block 31 gradually increases from top to bottom in the vertical direction, the first spring 32 drives the wedge block 31 to rise in the vertical direction and makes part of the wedge block 31 extend out of the limiting groove 21, the limiting assembly 3 also includes a limiting plate 33 movably arranged in the slide groove 22 and a second spring 34 abutting against the limiting plate 33, the limiting plate 33 abuts against the side surface of the wedge block 31 in the width direction and the second spring 34 drives the limiting plate 33 The movable seat 1 is provided with a movable seat 4 which can be moved in the horizontal direction and a first driving component 5 which is transmission-connected with the movable seat 4. The movable seat 4 is provided with a lifting and lowering mounting frame 6 and a first driving component 5 which is transmission-connected with the movable seat 4. The mounting frame 6 is transmission-connected to the second driving component 7, and the mounting frame 6 is provided with a clamping component 8 for clamping the curb 100. After the clamping component 8 clamps the curb 100, the first driving component 5 drives the movable seat 4 to move in the horizontal direction, and the second driving component 7 drives the mounting frame 6 to move in the vertical direction, so as to transport the curb 100, so as to place the curb 100 in one of the limiting components 3 or take the curb 100 out of the limiting component 3 and place it in a designated position on the ground.

[0027] Specifically, the working process of the curbstone transporting device for road construction provided in this embodiment is as follows: when placing the curbstone 100 on the movable seat 1, the clamping assembly 8 first clamps the curbstone 100 and drives the mounting frame 6 to rise to lift the curbstone 100 through the second driving assembly 7, and then drives the movable seat 4 to move through the first driving assembly 5 to transport the curbstone 100 to a position aligned with the wedge block 31 in one of the limiting assemblies 3, and the mounting frame 6 is driven down by the second driving assembly 7 to place the curbstone 100 on the wedge block 31. At this time, the pressure generated by the curbstone 100 on the wedge block 31 drives the wedge block 31 to retract into the limiting groove 21 and compress the first spring 32. As the wedge block 31 descends, the second spring 34 extends and pushes the limiting plate 3 3 approaches the curb 100 until the limiting plates 33 abut against the curb 100, at which time the limiting plates 33 on both sides of the wedge block 31 clamp the curb 100 to limit the curb 100, and the clamping assembly releases the curb 100 after the curb 100 is placed; when the curb 100 is removed from the movable seat 1, the clamping assembly 8 clamps the curb 100 and drives the mounting frame 6 to rise through the second driving assembly 7 to pull the curb 100 out of the space surrounded by the limiting plates 33, and during the rising process of the curb 100, the wedge block 31 rises under the drive of the first spring 32, and pushes each limiting plate 33 to reset so that the limiting plate 33 is away from the curb 100, and after the curb 100 is separated from the limiting assembly 3, the curb 100 can be transported to the specified position by moving the movable seat 4. The curbstone transporting device for road construction provided in this embodiment can effectively prevent the curbstone 100 from tipping over and colliding with each other during transportation, ensure that the curbstone 100 remains intact during transportation, avoid damage to the curbstone 100 that affects subsequent use, and is simple to operate and easy to use.

[0028] like Figure 3 and Figure 4As shown, a vertical first guide rod 23 is provided in the limiting groove 21, a first guide hole 37 matched with the first guide rod 23 is provided on the wedge block 31, the first spring 32 is sleeved on the first guide rod 23, and the opposite ends of the first spring 32 in the expansion and contraction direction are respectively in contact with the wedge block 31 and the moving seat 1. The first guide rod 23 is used to limit the moving direction of the wedge block 31 on the support seat 2, ensuring that the wedge block 31 descends in the vertical direction after being pressed by the curb 100, so that the limiting plates 33 located on both sides of the wedge block 31 move toward the curb 100 at the same time, and the first spring 32 is sleeved on the first guide rod 23, so that the first spring 32 remains in contact with the wedge block 31, and the first spring 32 is prevented from being separated from the wedge block 31 during the movement of the wedge block 31.

[0029] In detail, a horizontal second guide rod 24 is provided in the slide groove 22, a second guide hole 38 matching with the second guide rod 24 is provided on the limit plate 33, the second spring 34 is sleeved on the second guide rod 24, and the opposite ends of the second spring 34 in the expansion and contraction direction are respectively in contact with the limit plate 33 and the support seat 2. The second guide rod 24 is provided in the slide groove 22 to guide the limit plate 33 to move in the slide groove 22, so as to prevent the limit plate 33 from deviating from the preset direction when moving, causing the limit plate 33 to stagger with the curb 100, and the second spring 34 is sleeved on the second guide rod 24 so that the second spring 34 keeps in contact with the limit plate 33, so as to improve the structural stability of the curb handling device for road construction.

[0030] like Figure 4 and Figure 5 As shown, the limiting plate 33 includes a mounting portion 35 and a limiting portion 36 which are perpendicular to each other, the mounting portion 35 is provided with a guiding inclined surface 39 which fits with the wedge block 31 and the second guiding hole 38 is arranged on the side of the mounting portion 35 away from the wedge block 31, and the limiting portion 36 extends out of the slide groove 22. The limiting plate 33 is composed of a mounting portion 35 and a limiting portion 36 which are perpendicular to each other, wherein the mounting portion 35 is received in the slide groove 22 and a guiding inclined surface 39 which fits with the wedge block 31 is provided on the mounting portion 35, so that the cooperation between the limiting plate 33 and the wedge block 31 remains stable. When the limiting plate 33 is close to the curb 100, the limiting portion 36 is in direct contact with the curb 100, and the limiting portion 36 is inclined on a side close to the curb 100, so that the distance between the limiting portion 36 and the curb 100 gradually increases from bottom to top in the vertical direction, so as to facilitate the curb 100 to be pulled out from the space enclosed by the limiting plates 33 located on both sides of the wedge block 31.

[0031] Please combine Figure 1 and Figure 2 In this embodiment, the first driving assembly 5 includes a motor 51 and a screw rod 52 disposed at the output end of the motor 51. The screw rod 52 is rotatably disposed on the movable seat 1 and the axial direction of the screw rod 52 is consistent with the arrangement direction of the limiting grooves 21. The movable seat 4 is provided with a threaded hole that matches the screw rod 52. The motor 51 drives the screw rod 52 to rotate, and the movable seat 4 can be driven to move along the axial direction of the screw rod 52 through the cooperation between the screw rod 52 and the threaded hole, thereby driving the movable seat 4 to move in the horizontal direction, and accurately controlling the travel of the movable seat 4 to transport the curb 100 to the top of the corresponding wedge block 31, while ensuring that the clamping assembly 8 is aligned with the curb 100 during the process of clamping the curb 100, which is conducive to improving the reliability of the curb transporting device for road construction.

[0032] Specifically, the movable seat 1 is further provided with a guide rail 11, the length of which is consistent with the moving direction of the movable seat 4, and the movable seat 4 is provided with a slider that cooperates with the guide rail 11. The guide rail 11 is provided on the movable seat 1 to guide the movement of the movable seat 4, and the friction between the movable seat 4 and the movable seat 1 can be reduced by the cooperation between the slider and the guide rail 11, thereby improving the stability of the movable seat 4 when moving.

[0033] like Figure 1 and Figure 2 As shown, the second driving assembly 7 includes a first cylinder 71 and a first telescopic rod 72 arranged at the output end of the first cylinder 71, the telescopic direction of the first telescopic rod 72 is the vertical direction, and the end of the first telescopic rod 72 away from the first cylinder 71 is fixedly connected to the mounting frame 6. When the first telescopic rod 72 is extended or retracted into the first cylinder 71 under the drive of the first cylinder 71, the mounting frame 6 moves in the vertical direction driven by the first telescopic rod 72, realizing the lifting action of the mounting frame 6 in the vertical direction and driving the clamping assembly 8 to move, so that the curb 100 is lifted or lowered and the curb 100 is transported through the action of the mounting frame 6.

[0034] Please refer to Figure 2 , Figure 5 and Figure 6The clamping assembly 8 includes two clamping jaws 81 symmetrically arranged on the mounting frame 6 and a third driving assembly 82 respectively connected to the two clamping jaws 81 in transmission. The ends of the two clamping jaws 81 are respectively provided with a rotatable clamping plate 83 and the third driving assembly 82 drives the ends of the two clamping jaws 81 provided with the clamping plate 83 to move closer to or away from each other. When the two clamping jaws 81 are driven to open by the third driving component 82, one end of the two clamping jaws 81 provided with the clamping plate 83 moves away from each other. At this time, the curb 100 to be transported can be placed between the two clamping plates 83 by moving the movable seat 4 and the mounting frame 6, and then the two clamping jaws 81 are driven to approach each other by the third driving component 82 so that the two clamping plates 83 respectively abut against the opposite sides of the curb 100. As the clamping jaws 81 continue to rotate, the clamping plates 83 respectively rotate relative to the clamping jaws 81 and press on the curb 100, so that the curb 100 can be clamped and transported. After the curb 100 is transported to the designated position, the third driving component drives one end of the two clamping jaws 81 provided with the clamping plate 83 to move away from each other to release the curb 100. The operation is simple and convenient.

[0035] In detail, the third driving assembly 82 includes a second cylinder 84 and a second telescopic rod 85 disposed at the output end of the second cylinder 84, wherein one end of the second cylinder 84 away from the second telescopic rod 85 is rotatably connected to one of the clamping jaws 81, and one end of the second telescopic rod 85 away from the second cylinder 84 is rotatably connected to the other clamping jaw 81. The second cylinder 84 drives the second telescopic rod 85 to extend or retract the second cylinder 84 to control the rotation direction and rotation amplitude of the clamping jaw 81, and when the second telescopic rod 85 extends the second cylinder 84, the ends of the two clamping jaws 81 provided with the clamping plate 83 are close to each other, and when the second telescopic rod 85 is retracted into the second cylinder 84, the ends of the two clamping jaws 81 provided with the clamping plate 83 are away from each other, thereby conveniently controlling the opening or tightening of the clamping jaw 81.

[0036] Please combine Figure 5 and Figure 6 The clamping jaw 81 is provided with a mounting hole 86, and the cross section of the mounting hole 86 is fan-shaped. The clamping plate 83 is provided with a mounting rod 87, and the mounting rod 87 extends into the mounting hole 86, and the cross section of the mounting rod 87 is semicircular. The mounting rod 87 cooperates with the mounting hole 86 to limit the angle at which the clamping plate 83 can rotate relative to the clamping jaw 81, so that the clamping plate 83 can fit the surface of the curb 100 when the clamping jaw 81 approaches the curb 100, preventing the side of the clamping plate 83 from abutting against the curb 100 due to the automatic rotation of the clamping plate 83, resulting in insufficient clamping force, thereby reducing the risk of the curb 100 being loosened from the clamping assembly 8 during transportation.

[0037] In this embodiment, the two clamping plates 83 are provided with anti-skid pads 88 on the sides close to each other, and the anti-skid pads 88 have rough surfaces. Providing the anti-skid pads 88 on the surfaces of the clamping plates 83 in contact with the curbstone 100 can increase the friction between the clamping plates 83 and the curbstone 100, ensure that the position of the curbstone 100 on the clamping assembly 8 remains stable after the curbstone 100 is clamped by the clamping assembly 8, and prevent the curbstone 100 from falling off due to the separation of the clamping plates 83 during transportation.

[0038] like Figure 1 and Figure 2 As shown, the moving seat 1 is also provided with a walking wheel 12 and a push rod 13. The number of the walking wheels 12 is multiple and the multiple walking wheels 12 are arranged at intervals on the moving seat 1. The push rod 13 is arranged near one end of the moving seat 1. The moving seat 1 can be moved on the ground by arranging the walking wheel 12 on the moving seat 1, and the push rod 13 is arranged at one end of the moving seat 1. The moving seat 1 can be pushed to move by operating the push rod 13, so as to move the moving seat 1 to the target position, which is convenient for operators to carry out the handling operation of the curb 100.
