Description

Technical Field

[0001] The present application relates to the field of airport concrete pavement maintenance equipment, and in particular to a mobile pavement curing cloth laying device. Background Art

[0002] After the airport runway is poured, the concrete pavement needs to be maintained. At this time, the operator needs to lay the curing cloth on the airport runway and then water it regularly for maintenance. When laying the curing cloth, the operator usually places the curing cloth on the airport runway and then rolls the curing cloth to spread it. When laying the curing cloth, the operator has a lot of labor. Summary of the invention

[0003] In order to reduce the workload of operators when paving curing cloth, the present application provides a mobile pavement curing cloth paving device.

[0004] The present application provides a mobile road curing cloth laying device adopting the following technical solution:

[0005] A mobile road curing cloth laying device comprises two door-shaped half frames arranged opposite to each other, universal wheels are installed on the half frames, the tops of the two half frames are connected to horizontally arranged connecting pipes, the two connecting pipes are located between the two half frames, a plug-in rod is commonly plugged into the two connecting pipes, the curing cloth roll is sleeved on the connecting pipe and the plug-in rod, and a reinforcing piece is provided between the two half frames to stabilize the connection of the two half frames, and the length of the reinforcing piece is retractable.

[0006] By adopting the above technical scheme, when laying the curing cloth, the operator places the two half frames on both sides of the runway respectively, aligns the two connecting tubes, inserts the connecting rod into the curing cloth roll, and inserts the two ends of the connecting rod into the corresponding connecting tubes, so that the curing cloth roll can be placed on the two half frames, and then one side of the curing cloth is fixed to the ground, and the two operators each push the half frame to move along the runway at the same time. During the movement of the half frame, the fixed side of the curing cloth pulls the curing cloth roll to rotate, thereby releasing the curing cloth and completing the laying of the curing cloth. In the process of laying the curing cloth, the operator is less likely to bend over to push the curing cloth to unroll, thereby reducing the workload of the operator when spreading the curing cloth.

[0007] Optionally, the reinforcement member includes a reinforcement sleeve fixedly connected to the half frame, the two reinforcement sleeves are aligned, and the openings of the two reinforcement sleeves are close to each other, and a reinforcement rod is inserted between the two reinforcement sleeves.

[0008] By adopting the above technical solution, after the two half frames are placed, the two ends of the reinforcement rod are inserted into the corresponding reinforcement sleeves. When the half frames move, the reinforcement rod cooperates with the reinforcement sleeve to make the connection between the two half frames more stable.

[0009] Optionally, a handle is fixedly connected to the half frame.

[0010] By adopting the above technical solution, a fulcrum is provided for the operator, so that the operator can push the half frame to move more conveniently.

[0011] Optionally, a limiting component for limiting the health-preserving cloth roll is provided on the connecting pipe.

[0012] By adopting the above technical solution, the limiting component limits the health-preserving cloth roll, so that the health-preserving cloth released from the health-preserving cloth roll remains aligned with the road surface of the runway.

[0013] Optionally, the limiting assembly includes limiting pins corresponding to the connecting pipes one by one, the connecting pipes are provided with a plurality of limiting holes arranged along the axial direction of the connecting pipes, the limiting holes are adapted to the limiting pins, and a hand wheel is connected to the top of the limiting pins.

[0014] By adopting the above technical solution, after the health-care cloth roll is put on the plug-in rod and the connecting pipe, the position of the health-care cloth roll is adjusted so that the health-care cloth roll is located directly above the runway surface, and then the limit pin is inserted into the corresponding limit hole. The two limit pins cooperate to limit the health-care cloth roll; the handwheel provides a fulcrum for the operator, and at the same time the handwheel can prevent the limit pin from falling naturally through the limit hole under the action of gravity.

[0015] Optionally, a pressing component for limiting the position of the health-preserving cloth is provided between the two half frames.

[0016] By adopting the above technical solution, the pressing component presses the health-preserving cloth downward, so that the released health-preserving cloth can better fit the runway surface.

[0017] Optionally, the half frame includes two columns and a push rod, the push rod is located between the two columns, the end of the push rod is fixed to the top of the column, and the pressing assembly is arranged on a column located on the same side of the two half frames;

[0018] The pressing assembly includes an L-shaped end frame, which includes a vertical portion and a horizontal portion perpendicular to the vertical portion. The vertical portion is detachably connected to the corresponding column by bolts. A hollow pressing roller is provided between the two horizontal portions, and both ends of the pressing roller are sleeved on the corresponding horizontal portions.

[0019] By adopting the above technical solution, when placing the two half frames, the connecting rod is located in front of the lower pressure roller, and the front refers to the forward direction of the half frame. The health-preserving cloth is pulled to make the health-preserving cloth be located below the lower pressure roller. The bolts are turned to release the fixation of the end frame and the column. Then the end frame is rotated. The end frame drives the lower pressure roller to rotate, thereby adjusting the position of the lower pressure roller, so that the operator can adjust the distance between the health-preserving cloth and the runway surface according to the actual working conditions. After the adjustment, the bolts are turned to fix the end frame and the column.

[0020] Optionally, grooves are provided on the vertical portion and the column, so that the contact position between the vertical portion and the column is surface contact.

[0021] By adopting the above technical solution, the connection between the end frame and the column is made more stable.

[0022] In summary, the present application includes at least one of the following beneficial technical effects:

[0023] 1. The half frame, universal wheel, connecting pipe and plug-in rod are set to reduce the workload of operators when paving the curing cloth;

[0024] 2. By setting up reinforcement sleeves and reinforcement rods, the connection between the two half frames is made more stable;

[0025] 3. By setting the end frame and the lower pressure roller, the released health-preserving cloth can better fit the runway surface. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0030] The following is combined with Figure 1-3 This application is described in further detail.

[0031] The present application embodiment discloses a mobile road curing cloth laying device, referring to Figure 1 , including two door-shaped half frames 1 arranged opposite to each other, the half frame 1 includes two vertically arranged columns 11 and a horizontal top rod 12, the top rod 12 is located between the two columns 11, and the end of the top rod 12 is fixed to the top of the column 11; the lower end of the column 11 is equipped with a universal wheel for easy movement and steering.

[0032] The middle of the two top rods 12 are connected with a horizontally arranged connecting pipe 2, and the two connecting pipes 2 are located between the two half frames 1. The two connecting pipes 2 are commonly plugged with a plug rod 3. The health-care cloth roll is sleeved on the connecting pipe 2 and the plug rod 3, so that the health-care cloth roll can be supported. The connecting pipe 2 and the plug rod 3 cooperate to make the distance between the two half frames 1 adjustable, so as to adapt to different widths of road surfaces. One end of the top rod 12 is also fixedly connected with a handle 14 to provide a fulcrum for the operator to facilitate the movement of the half frame 1.

[0033] A reinforcing member 4 is provided between the two top rods 12 to stabilize the connection between the two half frames 1. The length of the reinforcing member 4 is retractable to adapt to runways of different widths. The reinforcing member 4 includes a reinforcing sleeve 41 fixedly connected to the end of the top rod 12 away from the handle 14. The two reinforcing sleeves 41 are also located between the two top rods 12. The two reinforcing sleeves 41 are aligned, and the openings of the two reinforcing sleeves 41 are close to each other. A reinforcing rod 42 is inserted between the two reinforcing sleeves 41. The reinforcing rod 42 and the reinforcing sleeve 41 can slide together to adjust the distance between the two half frames 1, and at the same time make the connection between the two half frames 1 more stable.

[0034] Reference Figure 1 and Figure 2 In order to keep the health-preserving cloth roll aligned with the runway surface, a limiting component 5 for limiting the health-preserving cloth roll is provided on the connecting tube 2. The limiting component 5 includes a limiting pin 51 corresponding to the connecting tube 2 one by one, and a plurality of limiting holes 21 arranged along the axial direction of the connecting tube 2 are provided on the connecting tube 2, and the limiting holes 21 are adapted to the limiting pin 51. A hand wheel 52 is also connected to the top of the limiting pin 51 for easy operation. After the health-preserving cloth roll is sleeved on the plug-in rod 3 and the connecting tube 2, the position of the health-preserving cloth roll is adjusted, and then the limiting pin 51 is inserted into the corresponding limiting hole 21, so as to limit the health-preserving cloth roll.

[0035] A pressing assembly 6 for limiting the position of the released health-preserving cloth is also provided between the two half frames 1. The pressing assembly 6 is arranged on the column 11 away from the reinforcing rod 42, and includes an L-shaped end frame 61 fixed to the column 11 by bolts, and the end frame 61 includes a vertical portion 611 and a horizontal portion 612 perpendicular to the vertical portion 611, and the vertical portion 611 is detachably connected to the corresponding column 11 by bolts.

[0036] A lower pressure roller 62 is provided between the two horizontal parts 612. The lower pressure roller 62 is a hollow tube. Both ends of the lower pressure roller 62 are sleeved on the corresponding horizontal parts 612 and can rotate freely. The horizontal parts 612 cooperate with the lower pressure roller 62. It can adapt to road surfaces of different widths. When laying the health-preserving sheet, the lower pressure roller 62 can press the released health-preserving sheet downward to make it fit better with the road surface. In order to improve the stability of the connection between the end frame 61 and the column 11, notches are provided on the vertical part 611 and the column 11, so that the contact position between the vertical part 611 and the column 11 is surface contact, which increases the contact area.

[0037] Reference Figure 1 and Figure 3 When laying the health-preserving cloth, the operator places the two half frames 1 on both sides of the runway respectively, aligns the two connecting pipes 2, inserts the plug-in rod 3 into the health-preserving cloth roll, and inserts the two ends of the plug-in rod 3 into the corresponding connecting pipes 2, and inserts the reinforcement rod 42 into the corresponding reinforcement sleeve 41. At this time, the connection between the two half frames 1 is completed, and then the bolts fixing the end frame 61 and the column 11 are tightened. After adjusting the position of the end frame 61 and the lower pressure roller 62, the bolts are tightened to fix the end frame 61 and the column 11.

[0038] Then one side of the curing sheet is fixed on the ground, and two operators push the handles at the same time to make the two half frames 1 move along the runway at the same time. During the movement of the half frames 1, the fixed side of the curing sheet pulls the curing sheet roll to rotate, thereby releasing the curing sheet and completing the laying of the curing sheet. During the laying of the curing sheet, the operator is less likely to bend over to push the curing sheet to unroll, thereby reducing the workload of the operator when spreading the curing sheet.

[0039] The implementation principle of a mobile road curing cloth laying device in the embodiment of the present application is as follows: when laying the curing cloth, the operator first places two half frames 1 on both sides of the runway respectively, and stably connects them through the reinforcement 4. The curing cloth roll is sleeved on the connecting pipe 2 and the plug-in rod 3, and is limited by the limit assembly 5. In the process of pushing the half frame 1 to move, the curing cloth roll rotates and releases the curing cloth, and at the same time, the pressing assembly 6 presses the curing cloth down to make it fit with the road surface, thereby completing the laying of the curing cloth.

[0040] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
