Detailed Implementation

[0015] To better understand the purpose, structure, and function of this utility model, the following description, in conjunction with the accompanying drawings, provides a more detailed description of a curbstone backrest fabric spreading tool of this utility model.

[0016] like Figure 1 and Figure 2 As shown, a curb backrest fabric paving tool includes a support frame 1. The support frame 1 consists of a fabric frame 11 and a paving frame 12 hinged together by a corner connecting wheel set 2. Both the fabric frame 11 and the paving frame 12 consist of a top frame and left and right side frames. Vertical support leg pulleys 31 and height-adjustable vertical pulley legs 3 are installed on the bottom side of both the left and right side frames. The vertical support leg pulleys 31 on both sides of the vertical pulley legs 3 respectively roll to connect the paved road surface and the concrete road surface. The inner side of the right side frame... Guide wheels 41 are provided on the bottom sides of both the side and top frames, respectively rolling to connect the side and top surfaces of the curbstone. Guide wheels 41 and adjustable guide wheel legs 4 are installed on the inner side of the left frame. The guide wheels 41 of the movable guide wheel legs 4 are rolling to the other side of the curbstone. A dry mortar baffle 5 is provided on the inner side of the left frame. A mortar hopper 7 is provided on the mortar laying frame 11. A discharge port is provided on the lower side of the mortar hopper 7 on the back side of the curbstone. A mortar horizontal scraper 6 is provided laterally on the end side of the paving frame 12 away from the mortar laying frame 11.

[0017] In this embodiment, the support frame 1 adopts a 40 40 The keel is made of 3mm galvanized square tubes, and all connection nodes are fully welded. Specifically, the support frame 1 includes three rows of portal square tube keel frames 13, wherein two adjacent rows of portal square tube keel frames 13 are connected by a first connecting rod 14 to form a fabric frame 11, and a second connecting rod 15 is fixedly installed on the side of the third row of portal square tube keel frames 13 facing the middle row of portal square tube keel frames 13. The end of the second connecting rod 15 is hinged to the middle row of portal square tube keel frames 13 through a corner connecting wheel set 2 to form a paving frame 12.

[0018] The corner connecting wheel assembly 2 connects the fabric frame 11 and the paving frame 12, ensuring that the tool can smoothly slide along the edge of the structure when encountering corners or arc-shaped structures. The corner connecting wheel assembly 2 includes a fixed wheel set on the outside of the middle portal square tube keel frame 13 and a cantilever wheel set at the end of the second connecting rod 15. The fixed wheel and the cantilever wheel are connected by a pin.

[0019] The vertical pulley legs 3 are inserted into the vertical square tubes on both sides of the portal square tube frame 13, and are tightened and fixed by the limiting bolts 16 on the vertical square tubes through threaded connection. After the backrest paving height is adjusted vertically, it is fixed by the limiting bolts 16 to prevent the scraper from moving and affecting the paving quality.

[0020] A guide wheel 41 is installed on the lower side of the middle horizontal square tube of the portal frame 13 to balance the stability of the support frame 1 and ensure that the tool is placed stably and reliably on the curb. A movable guide wheel support leg 4 is installed on the inner side of the left vertical square tube of the portal frame 13. The movable guide wheel support leg 4 includes a horizontal fixed square tube 42 that is vertically fixed to the left vertical square tube, and a horizontal movable square tube 43 is inserted into the horizontal fixed square tube 42 and tightened and fixed by a limiting bolt 16 connected to the horizontal fixed square tube 42 by a threaded connection.

[0021] The mortar horizontal scraper 6 is welded and fixed below the horizontal fixed square tube 42. In the gap between the two portal square tube keel frames 13 of the paving frame 12, manual secondary leveling can be carried out to better level and compact the surface, achieving a better leveling effect.

[0022] Meanwhile, due to the height difference between the left and right sides of the curbstone, in order to ensure smooth and reliable travel, the ash hopper 7 adopts a center of gravity biased towards the concrete surface layer. By balancing the upper center of gravity, the paving tool is prevented from tipping over due to an unstable center of gravity.

[0023] This tool consists of two parts: a material placement section and a paving and leveling section. These two sections are connected by a corner connecting wheel assembly 2. Vertical support legs 31 and guide wheels 41 facilitate movement on the curbstone and concrete pavement, completing the material discharge and paving leveling of the curbstone backrest. The width and thickness of the dry-mixed mortar for the curbstone backrest are pre-controlled by adjusting the vertical support legs 3 and the movable guide wheel legs 4. Finally, the material is placed through the ash storage hopper 7 on the material placement frame 11 and the discharge port 71, which controls the discharge speed. The dry-mixed mortar in the ash storage hopper 7 is controlled within the pre-set width and thickness, and then leveled using a mortar horizontal scraper 6, ensuring that the dry-mixed mortar backrest sliding along the curbstone forms a consistent, dense, and reliable shape.

[0024] This utility model utilizes the top and sides of the already constructed concrete curbstone. Using the vertical pulley legs 3 and movable guide wheel legs 4 of the paving tool, dry-mixed mortar is evenly spread along the curbstone installation direction at equal intervals via a mortar hopper 7 located above the paving frame 11. Simultaneously, the weight of the mortar hopper 7 secures the support frame 1 firmly on top of the curbstone, preventing displacement. Then, the loose dry-mixed mortar is compacted and laid evenly along the curbstone installation position using a dry-mixed mortar baffle 5 and a mortar horizontal scraper 6 located inside the paving frame 12.

[0025] When a roundabout is provided, the route is set according to the curved curb. The corner connecting wheel group 2 set in the middle of the support frame 1 is used to divide the support frame 1 into two hinged front and rear parts, which ensures that the movable guide wheel support leg 4 and the vertical pulley support leg 3 slide along the curved curb, making it easy for this tool to be used normally when it encounters the back of the curved curb.

[0026] Compared with conventional segmented formwork construction, the curb backing material spreading tool of this embodiment is not only simple to operate and convenient to install and replace materials, but also can be formed in one construction, which greatly improves the quality and efficiency of curb backing forming in municipal engineering road construction. Especially when used in the case of roads with various curb shapes, the economic benefits are significantly improved.

[0027] It is understood that this utility model has been described through some embodiments, and those skilled in the art will recognize that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of this utility model. Furthermore, under the teachings of this utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are within the protection scope of this utility model.
