Although the remaining asphalt can be reused, repeated heating will consume more energy and cause energy waste, which is a significant deficiency. SUMMARY

[0005] In order to improve the problem of energy waste caused by repeated heating of asphalt during road repair projects, the present application provides a municipal road repairing and reinforcing device and a construction method thereof.

[0018] By adopting the technical scheme, when the piston rod of the lifting cylinder drives the lifting block to move downward to a lower position through the push plate, the lifting block drives the clamping arm to rotate until the lifting block moves to below the clamping arm, the clamping arm is turned back into the lifting groove under the action of the limiting compression spring, and when the piston rod of the lifting cylinder is retracted upward, the lifting block is clamped at the lower part of the lifting groove under the limiting action of the clamping arm until the push plate moves upward to drive the sliding block to move upward, at this time, the sliding block drives the clamping arm to turn out of the lifting groove through the pull line, and at this time, the lifting block can move upward smoothly.

[0019] Optionally, polytetrafluoroethylene is coated on the lifting block and the sliding block.

[0020] By adopting the technical scheme, the friction coefficient of polytetrafluoroethylene is small, and therefore the smoothness of the lifting block and the sliding block during movement is improved.

DETAILED DESCRIPTION

[0035] The following is combined with Figure 1-3 This application is described in further detail.

[0036] Example 1

[0037] The embodiment of the present application discloses a municipal road repair and reinforcement device.

[0038] Reference Figure 1 The municipal road repair and reinforcement equipment includes a cart 1, which is provided with a detection mechanism for measuring the amount of asphalt required for road repair, and a tamping mechanism for compacting the roadbed at the damaged part.

[0039] Reference Figure 1 When repairing a road surface, workers first completely break up the damaged area, remove the debris and dust, and then use a tamping machine to compact the roadbed in the pit to improve its bearing capacity.

[0040] Reference Figure 1 and Figure 2 The tamping mechanism includes a carrier frame 13 bolted to the trolley 1, and a lifting cylinder 14 electrically connected to the control system is bolted to the top of the carrier frame 13. The piston rod of the lifting cylinder 14 passes through the carrier frame 13 and is threadedly connected to a horizontal push plate 15.

[0041] Reference Figure 1 、 Figure 2 and Figure 3The lifting seat 16 is bolted on the trolley 1, and a lifting groove 161 is vertically formed on the lifting seat 16, and a lifting block 19 is slidably arranged in the lifting groove 161, and the cross sections of the lifting block 19 and the lifting groove 161 are both in dovetail shape, and the lifting block 19 extends out of the lifting groove 161 to the position right below the push plate 15.

[0042] With reference to Figure 1 , Figure 2 and Figure 3 , an L-shaped bearing arm 17 is bolted on the trolley 1 near the tail portion, and a plurality of reversing wheels 18 are bolted on the top of the bearing arm 17. The lifting block 19 is tied with a pull rope 20, the pull rope 20 passes through the reversing wheels 18, and a rammer 21 is tied on the pull rope 20.

[0043] With reference to Figure 1 , Figure 2 and Figure 3 , the worker pushes the trolley 1 to the position beside the pit, and then starts the lifting cylinder 14 through the control system, and the piston rod of the lifting cylinder 14 extends downward to drive the push plate 15 to move downward, and the push plate 15 drives the lifting block 19 to move downward, so that the pull rope 20 can pull the rammer 21 to be suspended.

[0044] With reference to Figure 1 , Figure 2 and Figure 3 , then the piston rod of the lifting cylinder 14 is retracted, the rammer 21 quickly falls to compact the roadbed at the pit, and the pull rope 20 pulls the lifting block 19 to quickly rise to reset.

[0045] With reference to Figure 1 , Figure 2 and Figure 3 , the opposite sides of the lifting seat 16 are respectively hinged with L-shaped clamping arms 22, and the lifting seat 16 is provided with an avoiding opening 162 for the one end of the clamping arm 22 to turn into the lifting groove 161, and the other end of the clamping arm 22 is supported by a limiting compression spring 23 between the outer side wall of the lifting seat 16, and the limiting compression spring 23 is located above the hinge of the clamping arm 22.

[0046] With reference to Figure 1 , Figure 2 and Figure 3 , under the action of the limiting compression spring 23, the one end of the clamping arm 22 turns into the limiting groove 201 through the avoiding opening 162, and when the lifting block 19 moves downward to below the clamping arm 22, the lifting block 19 is limited by the clamping arm 22 and cannot be reset upward.

[0047] With reference to Figure 1 , Figure 2 and Figure 3Two triggering members are arranged at a position between the outer wall of the lifting seat 16 relative to the avoidance opening 162 and the cylinder body of the lifting cylinder 14. One triggering member corresponds to one clamping arm 22, and the triggering member is used to release the limiting effect of the clamping arm 22 on the lifting block 19.

[0048] Reference Figure 1 、 Figure 2 and Figure 3 The trigger member includes a trigger seat 24 bolted to the lifting seat 16, and a trigger groove 241 is vertically opened on the trigger seat 24. The top end of the trigger groove 241 is closed and the bottom end is open. A slider 25 slides in the trigger groove 241, and the slider 25 extends out of the trigger groove 241 and is located above the push plate 15.

[0049] A return compression spring 26 is supported between the slider 25 and the top end of the trigger slot 241 , and a pull wire 27 is tied between the slider 25 and one end of the clamping arm 22 relative to the limit compression spring 23 .

[0050] Reference Figure 1 、 Figure 2 and Figure 3 When the piston rod of the lift cylinder 14 drives the push plate 15 upward, the push plate 15 first contacts the slider 25 and drives it upward, thereby compressing the return spring 26. The slider 25 pulls the clamping arm 22 via the pull wire 27 to rotate, so that the end of the clamping arm 22 located in the lift groove 161 is rotated out of the lift base 16 through the avoidance opening 162. At this time, the lift block 19 can quickly rise to reset.

[0051] Reference Figure 1 、 Figure 2 and Figure 3 Since the piston rod of the lifting cylinder 14 is about to be fully retracted when the lifting block 19 rises, the possibility of poor ramming effect caused by the slow retraction speed of the piston rod of the lifting cylinder 14 can be reduced.

[0052] Reference Figure 1 、 Figure 2 and Figure 3 The lifting block 19 and the slider 25 are both coated with polytetrafluoroethylene, which has a small friction coefficient and is therefore beneficial for improving the smoothness of the movement of the lifting block 19 and the slider 25.

[0053] Reference Figure 1 and Figure 2 The cart 1 has a clearance opening 101. The detection mechanism includes a mud bucket 2 located at the clearance opening 101. The mud bucket 2 contains pit-filling mud 3. Two lifting cylinders 4 are bolted to the cart 1 and are symmetrically distributed about the axis of the mud bucket 2. The piston rods of the lifting cylinders 4 are connected to the outside of the mud bucket 2.

[0054] The lower part of the trolley 1 is arranged with a cover plate 5 horizontally covering the pit, and the lower surface of the cover plate 5 is arranged with an elastic film 6, and the circumferential edge of the elastic film 6 is bonded with the cover plate 5.

[0055] The bottom of the mud loading barrel 2 is communicated with a mud conveying pipe 7 extending to the cover plate 5 and communicated with the cavity formed between the cover plate 5 and the elastic film 6, and a mud pressing assembly is arranged in the mud loading barrel for pressing the pit filling soft mud 3 into the cavity between the cover plate 5 and the elastic film 6.

[0056] Referring to Figure 1 and Figure 2 , after the subgrade ramming of the pit is completed, the worker pushes the trolley 1 to the directly above the pit, and starts the lifting cylinder 4 through the control system, and the piston rod of the lifting cylinder 4 is retracted downward until the mud loading barrel 2 completely covers the pit through the mud conveying pipe 7.

[0057] Thereafter, the worker applies extrusion force to the pit filling soft mud 3 in the mud loading barrel 2 through the mud pressing assembly, and the pit filling soft mud 3 enters the cavity between the cover plate 5 and the elastic film 6 through the mud conveying pipe 7.

[0058] Since the elastic film 6 is made of elastic material, it deforms under the action of the pit filling soft mud 3 until the pit filling soft mud 3 completely fills the pit, at which time the worker calculates the volume of the pit according to the amount of pit filling soft mud 3 remaining in the mud loading barrel 2, and then calculates and accurately controls the amount of asphalt required for pit repair.

[0059] Through the arrangement of the above-mentioned detection mechanism, the amount of asphalt required for road surface repair can be accurately calculated, which is beneficial to greatly reduce the remaining amount of asphalt, reduce the energy consumption of repeated heating of asphalt, and thus achieve the effect of energy saving.

[0060] Referring to Figure 1 and Figure 2 , the mud pressing assembly includes a mud pressing plate 8 arranged horizontally in the mud loading barrel 2, and the mud pressing plate 8 is located above the pit filling soft mud 3 and tightly and slidingly fitted with the inner wall of the mud loading barrel 2.

[0061] The top of the mud loading barrel 2 is bolted with a bearing rod 9, and the mud pressing plate 8 is welded with a screw rod 10 vertically sliding through the bearing rod 9, and the screw rod 10 is threadedly connected with a fastening nut 11 on the lower part of the rod body of the bearing rod 9.

[0062] The worker turns the fastening nut 11 with a tool, and the fastening nut 11 abuts against the lower surface of the bearing rod 9, so that the reaction force pushes the mud pressing plate 8 downward, thereby realizing the mud pressing action.

[0063] Referring to Figure 1 and Figure 2, reversely twist the fastening nut 11, then lift the screw 10 upward, and the pit-filling mud 3 between the cover plate 5 and the elastic membrane 6 is sucked back into the mud bucket 2 under the action of negative pressure.

[0064] Reference Figure 1 and Figure 2 A limit groove 201 is vertically opened on the inner side wall of the mud bucket 2, and the mud pressing plate 8 extends into the limit groove 201 and slides with it. The limit groove 201 limits the mud pressing plate 8, reducing the possibility of the mud pressing plate 8 rotating circumferentially and causing the mud pressing assembly to fail.

[0065] Reference Figure 1 and Figure 2 A mounting groove 202 is vertically opened between the inner and outer walls of the mud barrel 2, and a scale bar 12 is bonded in the mounting groove 202. Workers can quickly read the height of the mud pressing plate 8 through the scale bar 12, and then quickly calculate the required amount of asphalt.

[0066] The implementation principle of Example 1 is as follows: when repairing a road surface, workers first completely break up the damaged part of the road surface, and then remove the debris and dust to form a pit.

[0067] Afterwards, the worker pushes the cart 1 to the side of the pit, and then starts the lifting cylinder 14 through the control system. The piston rod of the lifting cylinder 14 extends downward, thereby driving the push plate 15 to move downward. The push plate 15 pushes the lifting block 19 downward to the bottom of the clamping arm 22, so that the pull rope 20 can pull the rammed earth block 21 up to be suspended in the air.

[0068] When the piston rod of the lifting cylinder 14 retracts, the lifting block 19 first remains stationary under the limiting action of the clamping arm 22 until the piston rod of the lifting cylinder 14 retracts upward to the push plate 15 to push the slider 25 to move. The slider 25 pulls the clamping arm 22 to move through the pull wire 27. The end of the clamping arm 22 located in the lifting groove 161 is rotated out of the lifting groove 161 through the avoidance opening 162. The lifting block 19 rises and resets, and the rammed earth block 21 falls to compact the roadbed in the pit.

[0069] When the path at the pit is completely compacted, the worker pushes the cart 1 to the top of the pit and starts the lifting cylinder 4 through the control system. The piston rod of the lifting cylinder 4 retracts downward until the mud bucket 2 drives the cover plate 5 to completely cover the pit through the mud pipe 7.

[0070] After that, the worker applies squeezing force to the pit-filling mud 3 in the mud bucket 2 through the mud pressing assembly, and the pit-filling mud 3 enters the cavity between the cover plate 5 and the elastic membrane 6 through the mud pipe 7 until the pit is completely filled with the pit. At this time, the worker reads the height of the mud pressing plate 8 according to the scale bar 12, and calculates the volume of the pit according to the amount of remaining pit-filling mud 3 in the mud bucket 2, and then calculates and accurately controls the amount of asphalt required for pit repair.

When the piston rod of the lifting cylinder 14 retracts, the lifting block 19 first remains stationary under the limiting action of the clamping arm 22, until the push plate 15 drives the sliding block 25 to move when the piston rod of the lifting cylinder 14 retracts upward, the sliding block 25 drives the clamping arm 22 to move through the pull wire 27, one end of the clamping arm 22 located in the lifting groove 161 turns out to the outside of the lifting groove 161 through the avoiding opening 162, the lifting block 19 rises and resets, and the ramming block 21 falls to compact the roadbed at the pit.
