Description

Technical Field

[0001] This application relates to the field of road surface reinforcement technology, and in particular to a shallow road surface grouting device. Background Technology

[0002] Road surface reinforcement refers to the measures taken to restore or improve the performance of a road surface when its surface properties and load-bearing capacity decline with age and its structural condition or surface function no longer meet the requirements. These measures involve adding a reinforcement layer to the road surface. With the rapid increase in traffic volume and load, as well as the emergence of overloaded vehicles, previously constructed cement concrete pavements have suffered varying degrees of damage, thus requiring the use of grouting devices to reinforce the road surface.

[0003] Existing grouting equipment includes a grouting body, a grouting head, and a connecting pipe for connecting the grouting body and the grouting head. During the grouting process, workers need to hold the grouting head and manually adjust its position and height. However, the grouting body generates significant vibration during grout delivery, which in turn causes the grouting head to vibrate, resulting in heavy hand strain and increased workload for workers.

[0004] Regarding the aforementioned technologies, the inventors believe that the grouting head requires manual support and adjustment during operation, and that the grouting head generates vibration, thereby increasing the workload of the workers. Utility Model Content

[0005] To address the aforementioned technical problems, this application provides a shallow road grouting device.

[0006] This application provides a shallow road grouting device, which adopts the following technical solution:

[0007] A shallow road grouting device includes a grouting body, a grouting head, and a connecting pipe for connecting the grouting body and the grouting head. The grouting head is connected to a mobile vehicle. The mobile vehicle includes a base plate, a push-pull handle connected to the base plate, and casters disposed at the bottom of the base plate. The base plate is provided with a limiting mechanism for limiting the movement of the mobile vehicle, a clamping mechanism for clamping the grouting head, and a height adjustment mechanism for adjusting the height of the clamping mechanism. A through hole is provided on the base plate, through which the grouting head passes to grout the road surface.

[0008] By adopting the above technical solution, the clamping mechanism is used to clamp and fix the grouting head. The grouting head can be moved to the grouting position by a moving trolley. The limiting mechanism limits the moving trolley, so that the moving trolley and the grouting head are stably set in the grouting position, thus eliminating the need for manual handling or support. The height adjustment mechanism drives the grouting head to extend into the grouting hole for grouting, eliminating the need for manual adjustment of the grouting head's height, thereby reducing the labor intensity of workers.

[0009] Preferably, the limiting mechanism includes a first electric telescopic rod disposed on the base plate and a telescopic groove formed at the bottom of the base plate. The telescopic end of the first electric telescopic rod extends into the telescopic groove and is connected to the universal wheel. The first electric telescopic rod is used to drive the universal wheel to retract into the telescopic groove, thereby making the base plate abut against the ground.

[0010] By adopting the above technical solution, the first electric telescopic rod drives the casters to extend out of the telescopic groove, thereby facilitating the movement of the mobile vehicle and adjusting the position of the grouting head. When the first electric telescopic rod drives the casters back into the telescopic groove, the base plate contacts the ground, thus improving the stability of the mobile vehicle and the grouting head during the grouting process.

[0011] Preferably, the bottom of the base plate is provided with a first anti-slip pad.

[0012] By adopting the above technical solution, the first anti-slip pad comes into contact with the ground, thereby further improving the stability of the mobile vehicle and the grouting head during the grouting process.

[0013] Preferably, the height adjustment mechanism includes a second electric telescopic rod and a connecting block. One end of the second electric telescopic rod is connected to the base plate, and the other end is connected to the connecting block. The connecting block is connected to the clamping mechanism.

[0014] By adopting the above technical solution, the second electric telescopic rod drives the connecting block to rise and fall, thereby driving the clamping mechanism and the grouting head to rise and fall, and thus adjusting the height of the grouting head to facilitate grouting into the grouting hole.

[0015] Preferably, there are multiple height adjustment mechanisms, which are arranged in a circular array on the outside of the clamping mechanism.

[0016] By adopting the above technical solution, multiple height adjustment mechanisms improve the stability of the clamping mechanism and the grouting head during the lifting and lowering process, thereby improving the stability of the grouting process of the grouting head.

[0017] Preferably, the clamping mechanism includes a mounting ring connected to the connecting block, a plurality of adjusting screws symmetrically arranged on the mounting ring, a limiting rod, a clamping plate, and an adjusting handle. The adjusting screws are threadedly connected to the mounting ring, one end of the adjusting screw near the axis of the mounting ring is rotatably connected to the clamping plate, and the other end is fixedly connected to the adjusting handle. The limiting rod is fixedly connected to the clamping plate and slidably connected to the mounting ring. The limiting rod is arranged parallel to the adjusting screws.

[0018] By adopting the above technical solution, rotating the adjustment handle can drive the adjustment screw to rotate, and the adjustment screw and the limit rod can drive the clamping plate to clamp and fix the grouting head, thereby realizing the clamping and fixing of the grouting head and improving the stability of the grouting head during the grouting process.

[0019] Preferably, the clamping plate has an arc-shaped structure, and a second anti-slip pad is provided at the end of the clamping plate away from the adjusting screw.

[0020] By adopting the above technical solution, the arc-shaped clamping plate increases the contact area with the grouting head, thereby improving the clamping stability of the grouting head and thus improving the stability of the grouting head during the grouting process.

[0021] Preferably, a limiting plate is provided at one end of the clamping plate near the base plate, and the limiting plate is perpendicular to the clamping plate.

[0022] By adopting the above technical solution, the limiting plate limits and fixes the grouting head, further improving the clamping stability of the grouting head.

[0023] In summary, this application has the following beneficial technical effects:

[0024] 1. The grouting head is fixed by the clamping mechanism on the mobile vehicle. The first electric telescopic rod drives the universal wheel to retract into the telescopic groove, so that the first anti-slip pad on the base plate contacts the ground. Then, the second electric telescopic rod drives the clamping mechanism and the grouting head to rise and fall, so that the grouting head completes the grouting process without manual support and adjustment, reducing the labor intensity of the workers.

[0025] 2. The clamping plate is designed with an arc shape and is equipped with a second anti-slip pad and a limiting plate, which improves the clamping stability of the grouting head and further enhances the stability of the grouting process. Attached Figure Description

[0033] Reference Figure 1 and Figure 2 A shallow road grouting device includes a grouting body 1, a grouting head 2, and a connecting pipe 3 for connecting the grouting body 1 and the grouting head 2. The grouting head 2 is connected to a mobile vehicle 4, which includes a base plate 41, a push-pull handle 42 fixedly connected to the base plate 41, and casters 43 fixedly mounted on the bottom of the base plate 41. The base plate 41 is provided with a limiting mechanism 5 for limiting the movement of the mobile vehicle 4, a clamping mechanism 6 for clamping the grouting head 2, and a height adjusting mechanism 7 for adjusting the height of the clamping mechanism 6. A through hole 411 is provided on the base plate 41, through which the grouting head 2 passes to grout the road surface.

[0034] The limiting mechanism 5 includes a first electric telescopic rod 51 fixedly mounted on the base plate 41 and a telescopic groove 52 formed at the bottom of the base plate 41. The telescopic end of the first electric telescopic rod 51 extends into the telescopic groove 52 and is fixedly connected to the caster wheel 43. The first electric telescopic rod 51 is used to drive the caster wheel 43 back into the telescopic groove 52, thereby making the base plate 41 abut against the ground. A first anti-slip pad 44 is fixedly mounted on the bottom of the base plate 41.

[0035] The height adjustment mechanism 7 includes a second electric telescopic rod 71 and a connecting block 72. One end of the second electric telescopic rod 71 is fixedly connected to the base plate 41, and the other end is fixedly connected to the connecting block 72. The connecting block 72 is connected to the clamping mechanism 6.

[0036] There are two height adjustment mechanisms 7, which are arranged in a circular array on the outside of the clamping mechanism 6.

[0037] Reference Figure 1 , Figure 3 and Figure 4 The clamping mechanism 6 includes a mounting ring 61 fixedly connected to the connecting block 72, two adjusting screws 62 symmetrically arranged on the mounting ring 61, a limiting rod 63, a clamping plate 64, and an adjusting handle 65. The adjusting screws 62 are threadedly connected to the mounting ring 61. One end of the adjusting screw 62 near the axis of the mounting ring 61 is rotatably connected to the clamping plate 64 via a bearing, and the other end is fixedly connected to the adjusting handle 65.

A limiting hole 66 is provided on the mounting ring 61, and the limiting rod 63 is slidably connected to the limiting hole 66. The limiting rod 63 is arranged parallel to the adjusting screws 62.

[0038] The clamping plate 64 has an arc-shaped structure, and a second anti-slip pad 67 is fixedly provided at the end of the clamping plate 64 away from the adjusting screw 62. A limiting plate 68 is fixedly provided at the end of the clamping plate 64 near the base plate 41, and the limiting plate 68 is perpendicular to the clamping plate 64.

[0039] The implementation principle of a shallow road grouting device according to an embodiment of this application is as follows: Rotating the adjusting handle 65 drives the adjusting screw 62 to rotate, and the limiting rod 63 limits the clamping plate 64, thereby clamping and fixing the grouting head 2. The first electric telescopic rod 51 drives the universal wheel 43 to extend out of the telescopic groove 52. Workers move the base plate 41 to the required grouting position by pushing and pulling the handle 42. Then, the first electric telescopic rod 51 drives the universal wheel 43 to retract into the telescopic groove 52, causing the first anti-slip pad 44 at the bottom of the base plate 41 to contact the ground. Then, the second electric telescopic rod 71 drives the grouting head 2 into the grouting hole for grouting. During the grouting process, there is no need for manual support or adjustment of the grouting head 2, thus reducing the labor intensity of the workers.

[0040] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
