Description

Technical Field

[0001] The utility model relates to the technical field of road maintenance equipment, in particular to a curbstone renovation machine. Background Art

[0002] A curbstone or kerbstone is a marker stone placed between the road surface and other structures. It mainly serves to mark the road boundary, protect the road surface and separate pedestrians from vehicles.

[0003] As time goes by and the natural environment affects the stone surface, dirt, dust and other pollutants will accumulate, causing the stone to become dull in color and rough on the surface, affecting the overall appearance. As roads are an important part of the city, their cleanliness and appearance directly affect the overall image of the city. Dealing with dirt and polishing the curbstones is one of the important measures to maintain the city's image and improve the quality of the city.

[0004] However, the current renovation method for curbstones is to renovate the outer surface of the curbstone through an angle grinder (a disc of a polishing machine). However, since the curbstone has an upper end face and a road side that need to be renovated, and the angle grinder can only process one side, and the length of the curbstone varies with the road setting, the efficiency of single-sided processing is low. Therefore, we propose a curbstone renovation machine to reduce the workload of curbstone renovation and improve efficiency. Utility Model Content

[0005] The purpose of the utility model is to solve the shortcomings of the prior art. At present, the renovation method of the curb stone is to renovate the outer surface of the curb stone by an angle grinder (a disc of a polishing machine). However, since the curb stone has an upper end face and a road side that need to be renovated, and the angle grinder can only process one side, and the length of the curb stone is set with the road, the efficiency of single-sided processing is low.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] A curbstone renovation machine includes an angle grinder and an angle grinder handheld frame. The angle grinder is provided in two groups. The angle grinder handheld frame consists of an upper plate and a side plate. The angle grinder is installed on the inner side of the upper plate and the side plate respectively. The upper plate and the side plate are rotatably connected through a rotating shaft, and an angle adjustment structure is provided between the upper plate and the side plate and the rotating shaft. The upper plate and the side plate are provided with movable wheels away from the rotating shaft end.

[0008] Furthermore, the angle grinder is fixed by bolts through the mounting brackets on the inner sides of the upper plate and the side plates, and then the angle grinder is installed, and the angle grinder is electrically connected to an external power supply.

[0009] Furthermore, handles are installed on the outer sides of the upper plate and the side plates.

[0010] Furthermore, springs are provided on the front and rear ends of the angle grinder located on the inner sides of the upper plate and the side plates, and a positioning plate is provided at the other end of the spring, and the positioning plate extends out of the grinding plate portion of the angle grinder.

[0011] Furthermore, the upper plate and the side plates are connected by several groups of plug blocks and slots, the plug blocks and the slots are adapted to each other, and the plug blocks are integrally formed with the upper plate, while the slots are provided on the side plates, the rotating shaft passes through the plug blocks and the slots to connect the upper plate and the side plates, and the side plates are extended at both ends respectively, the plug blocks are fixedly connected to the rotating shaft, and the rotating shaft is rotatably connected to the side plates.

[0012] Furthermore, the angle adjustment structure includes an adjusting rod and a fixed fan disc, the adjusting rod is fixedly connected to the side plate portion extending from the rotating shaft, the fixed fan disc is arranged on the upper plate near the side plate, and a connecting hole is penetrated at the end of the adjusting rod away from the rotating shaft. On the side of the fixed fan disc corresponding to the adjusting rod, fixing holes are provided along the angles of 85°, 90° and 95° between the adjusting rod and the side plate, and the internal thread of the connecting hole is connected to a threaded knob, and the screw of the threaded knob is adapted to the fixing hole and threadedly connected.

[0013] Furthermore, the moving wheels are arranged near the front and rear sides of the upper plate and the side plates, and the bottom of the moving wheels of the upper plate are installed toward the bottom of the upper plate, while the bottom of the moving wheels of the side plates are oriented in the same direction as the moving wheels of the upper plate.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] Double-sided simultaneous renovation: By installing angle grinders on the upper plate and side plates respectively, the upper end face and side faces of the curbstone can be renovated simultaneously, thus avoiding the tedious steps of processing different surfaces separately in traditional methods and improving work efficiency;

[0016] Adjustable angle (most curbstones on the market are 90°, but the production error may be between 85-95°, and due to installation errors, or special installation requirements or designs): By designing an angle adjustment structure, the angle between the upper plate and the side plate can be adjusted to meet the angle requirements of different curbstones, increasing the flexibility and versatility of the equipment, making it suitable for curbstone renovation operations in different scenarios and needs;

[0017] Easy to move and use: Moving wheels are set at the ends of the upper plate and side plates away from the rotating shaft, so that the entire refurbishing machine can be easily moved and positioned. When used in combination with the handheld handle, it improves work efficiency and convenience of operation.

[0018] High safety: The angle grinder is installed on the inner side of the upper plate and side plates to create a barrier between the angle grinder and the workers. The springs and positioning plates set at the front and back can control the pressing force after the positioning plates hit the edge stone, ensuring stable grinding. At the same time, the springs block the front and back ends to prevent debris from contacting the grinding disc.

[0019] In summary, this curbstone renovation machine improves the traditional renovation method and achieves the effects of double-sided simultaneous renovation, adjustable angle, convenient movement and high safety. It plays a positive role in improving the efficiency of curbstone renovation and maintaining the city's image. BRIEF DESCRIPTION OF THE DRAWINGS
