[0035] In the construction process of landscape engineering curb stone, the curb stone is heavy, and the traditional method needs manual carrying, which is time-consuming and laborious. At present, some construction devices for replacing manual carrying of curb stone appear on the market. These construction devices clamp the curb stone through clamping jaws, and then move the clamping jaws to realize carrying of the curb stone. Although these construction devices can carry the curb stone through the clamping jaws, the clamping jaws cannot actively grip the curb stone, and the fixation of the curb stone is not very firm.
[0036] To solve the above technical problems, refer to Figure 1 As shown in the figure, Figure 1 The present embodiment provides a curb stone carrying device, which comprises a support 1, a clamping jaw assembly 2 and a control assembly 3.
[0037] The front end of the support 1 is provided with a front support 11, the rear end is provided with an operating rod 12, and the middle part is provided with a wheel 13. The front support 11 is used to connect the clamping jaw assembly 2, the operating rod 12 is used to connect the control assembly 3, and the wheel 13 is used to facilitate the movement of the support 1.
[0038] The clamping jaw assembly 2 comprises a pair of clamping jaws 20, the clamping jaws 20 are crossly arranged in the middle part, and are rotatably connected with the front support 11 through a pin shaft, and the whole is in X shape. A pair of connecting parts 201 are arranged on the upper side of the pin shaft, and a pair of clamping parts 202 are arranged on the lower side of the pin shaft. The connecting parts 201 and the clamping parts 202 can be opened and closed at the same time.
[0039] The control assembly 3 comprises a brake wire 31 and a handle 32, the brake wire 31 is movably arranged on the support 1, and one end is connected with the connecting part 201, and the other end is connected with the handle 32, the handle 32 is movably connected with the operating rod 12, and is used for pulling the brake wire 31; wherein, when the handle 32 pulls the brake wire 31, the connecting part 201 rotates around the pin shaft under the traction of the brake wire 31, so that the two clamping parts 202 are close to each other and clamp the curbstone.
[0040] The curbstone carrying device of the above technical scheme works first, the pair of clamping parts 202 of the clamping jaw 20 are respectively placed on both sides of the curbstone, then the handle 32 pulls the brake wire 31, the connecting part 201 rotates around the pin shaft under the traction of the brake wire 31, so that the clamping parts 202 are close to each other and clamp the curbstone; finally, the support 1 is moved through the wheels 13, the curbstone is carried to the preset position, and the handle 32 is loosened to put down the curbstone. It can be seen that the curbstone carrying device of the above technical scheme can control the clamping parts 202 to be close to each other through the handle 32, and actively clamp the curbstone, compared with the prior art that the clamping jaw 20 naturally closes during lifting to clamp the curbstone, the active clamping method can improve the firmness of the curbstone during lifting, reduce the risk of accidental falling of the curbstone during carrying, and further improve the safety of construction.
[0041] In an embodiment in which the brake wire 31 is movably arranged on the support 1, the support 1 comprises a support body 14 and a straight pipe 10, both ends of the straight pipe 10 are connected with the front support 11 and the operating rod 12 respectively, the middle part is connected with the support body 14, the wheels 13 are arranged at the bottom of the support body 14, and the brake wire 31 is arranged in the inside of the straight pipe 10. In this way, the part of the brake wire 31 between the front support 11 and the operating rod 12 can be built in the straight pipe 10 and guided by the straight pipe 10, not only the brake wire 31 is well guided by the straight pipe 10, but also the protection and stability of the brake wire 31 are significantly improved, and the service life of the brake wire 31 is prolonged. In addition, this design also makes the structure of the whole device more compact and simple, and reduces the complexity of manufacturing and installation.
[0042] In order to make the straight pipe 10 has the length adjustment function, the straight pipe 10 includes the fixed section 101, the front telescopic section 102 and the rear telescopic section 103, the fixed section 101 is fixedly connected with the support body 14, and the two ends are movably sleeved with the front telescopic section 102 and the rear telescopic section 103 respectively; the front telescopic section 102 is connected with the front support 11, and the rear telescopic section 103 is connected with the operating rod 12; the screw bolt 15 for fixing the relative position is arranged between the front telescopic section 102 and the fixed section 101 and between the rear telescopic section 103 and the fixed section 101. This design makes the carrying device adapt to curb stones of different sizes or heights, thereby improving the application range and practicability of the device. At the same time, the installation and adjustment process is simplified: the relative positions of the front telescopic section 102, the rear telescopic section 103 and the fixed section 101 are fixed by the screw bolt 15, the user can conveniently adjust the length of the straight pipe 10, and the firmness of the connection is ensured after the adjustment is completed.
[0043] Exemplarily, the support body 14 is connected with the wheel 13 through the rotating shaft at the bottom end, the wheel 13 supports the support body 14, and the support body 14 can rotate around the rotating shaft to lift the front end jaw 20.
[0044] In order to improve the stability and smoothness of the gate line 31 in the transmission process, the front end of the front telescopic section 102 is provided with a guide roller shaft 104, the gate line 31 extends downward after passing through the guide roller shaft 104 and is connected with the connecting part 201. The guide roller shaft 104 is made of high-strength and wear-resistant materials, such as high-quality alloy steel or stainless steel, to ensure that it can withstand the friction and tension generated by the gate line 31 in the transmission process for a long time. The surface of the guide roller shaft 104 is finely polished and polished to further reduce the friction resistance between the guide roller shaft 104 and the gate line 31, so that the gate line 31 can more smoothly bypass the guide roller shaft 104 and extend downward. The guide roller shaft 104 can be pivotally connected to the pipe wall of the front telescopic section 102, and the rolling friction can further reduce the friction between the guide roller shaft 104 and the gate line 31.
[0045] In order to facilitate the planning of the transmission path of the gate line 31, the rear telescopic section 103 is provided with a let-in hole 105, and the gate line 31 is connected with the handle 32 after passing through the let-in hole 105. The shape of the let-in hole 105 is usually circular or elliptical to adapt to the diameter of the gate line 31 and the transmission path requirements. At the same time, the position of the let-in hole 105 needs to ensure that the gate line 31 will not be disturbed or hindered by other components in the transmission process. It is also important that the bending radius and transmission angle of the gate line 31 are controlled by the guidance of the let-in hole 105 to ensure the transmission efficiency and stability.
[0046] Exemplarily, the front telescopic section 102 is also provided with a let-in hole, so that the gate line 31 can extend out of the port of the front telescopic section 102 and also can extend out of the let-in hole.
[0047] In an embodiment in which the middle part of the clamping jaw 20 is rotatably connected to the front support 11 through a pin shaft, the front support 11 includes a pair of spaced apart connecting plates 16, and the clamping jaw 20 is rotatably arranged between the connecting plates 16. Among them, the connecting plates 16 are generally rectangular or parallelogram-shaped to meet the rotation requirements of the clamping jaw 20. At the same time, through holes for installing the pin shaft are also provided on both sides of the connecting plates 16, and the positions and sizes of these through holes are matched with the pin shaft to ensure that the pin shaft can be firmly installed between the connecting plates 16. The shape of the pin shaft is generally cylindrical to adapt to the through holes on the connecting plates 16. At the same time, some anti-skid or locking devices such as threads, clamping grooves, etc. can be provided at one end of the pin shaft to ensure that the clamping jaw 20 will not accidentally fall off or loosen during rotation.
[0048] Further, some reinforcing ribs or support frames are arranged between the connecting plates 16 to enhance the strength and stability of the connecting plates 16.
[0049] For example, the front support 11 is provided with a guide pipe 17 through which the gate line 31 passes. After passing through the guide roller shaft 104, the gate line 31 enters the guide pipe 17, then enters between the two connecting plates 16, and finally connects with the connecting part 201 of the clamping jaw 20.
[0050] For example, the guide pipe 17 is hinged with the front telescopic joint 102 through a pin shaft, so that the front support 11 can swing forward and backward to a certain extent to adapt to the movement of the curbstone, or the guide pipe 17 is fixedly connected with the front telescopic joint 102 and communicates with each other.
[0051] In an embodiment in which the gate line 31 is connected to the connecting part 201 at one end, the end of the gate line 31 is provided with two connecting lines 33, and the two connecting lines 33 are respectively connected to the two connecting parts 201. The structure formed between the two connecting lines 33 and the gate line 31 is inverted Y-shaped. When the gate line 31 pulls the two connecting lines 33, it can simultaneously drive the two connecting parts 201 to move closer to each other, thereby controlling the clamping part 202 to clamp the curbstone. Among them, the connecting part 201 is also provided with a connecting hole or a connecting groove matched with the connecting line 33 to realize the stable connection between the connecting line 33 and the connecting part 201. When the gate line 31 is subjected to external force, it will pull the two connecting lines 33 along the predetermined path. Since the two connecting lines 33 are respectively connected to the two connecting parts 201, the pulling force of the gate line 31 will simultaneously act on the two connecting parts 201. Under the action of the inverted Y-shaped structure, the two connecting parts 201 will be subjected to equal pulling force and move in opposite directions, so as to move closer to each other. This not only realizes the synchronous driving of the gate line 31 to the two connecting parts 201, but also improves the response speed and accuracy of the whole device.
[0052] In order to improve the stability of the clamping part 202 clamping the road stone, the inner side of the clamping part 202 is provided with a non-slip rubber pad 203. At the same time, the surface of the non-slip rubber pad 203 can be provided with some anti-slip or friction-increasing anti-slip patterns, protrusions, etc. to improve the clamping ability and stability of the clamping jaw 20.
[0053] In one embodiment in which the above-mentioned handle 32 is movably connected with the operating rod 12 and used to pull the brake cable 31, the handle 32 is rotatably connected with the operating rod 12 through a pivot and pulls the brake cable 31 when rotating around the pivot. When the user holds the handle 32 and rotates it around the pivot, the rotation of the handle 32 will be converted into a pulling force on the brake cable 31. This pulling force will be transmitted along the transmission path of the brake cable 31 to the connecting part 201 of the clamping jaw 20, thereby achieving the purpose of controlling the clamping of the clamping jaw 20.
[0054] In another embodiment in which the above-mentioned handle 32 is movably connected with the operating rod 12 and used to pull the brake cable 31, the handle 32 is movably installed on the operating rod 12, such as being telescopically sleeved in the telescopic hole of the operating rod and pulling the brake cable 31 by moving itself.
[0055] In one embodiment in which the handle 32 is movably connected with the operating rod 12 and used to pull the brake cable 31, the brake cable 31, the handle 32 and the clamping jaw 20 use the existing bicycle brake mechanism.
[0056] The above-mentioned is only an optional embodiment of the present application and does not limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
