Description

Technical Field

[0001] The present invention relates to the technical field of concrete pavement maintenance for municipal road and bridge engineering, and specifically provides a concrete pavement maintenance device and method for municipal road and bridge engineering. Background Technique

[0002] Road bridges generally consist of several major parts such as subgrade, pavement, bridge, tunnel engineering, and traffic engineering facilities. Most of them are generally paved with concrete. After the concrete pavement is paved, in order to make the setting effect of the concrete reach better strength, it needs to be maintained. During the concrete maintenance period, emphasis should be placed on strengthening the control of the humidity and temperature of the concrete, minimizing the exposure time of the surface concrete as much as possible, and promptly covering the exposed surface of the concrete tightly. Covers such as tarpaulins and plastic sheets can be used for covering to prevent the evaporation of surface moisture. Before the initial setting of the concrete in the exposed surface protective layer, the covering should be rolled up, and the surface should be rubbed and pressed with a trowel at least twice to make it flat and then covered again. When maintaining the concrete pavement of road bridges, it should be noted that the covering should not directly contact the concrete surface until the concrete has finally set.

[0003] However, there are still the following problems in the current process of maintaining concrete pavements: 1. In the process of maintaining concrete pavements, traditionally, the tarpaulin is generally opened and retracted by winding. This way of opening and retracting wastes time, is inconvenient to use, and when the tarpaulin is opened and retracted by winding, it will be over-wound, increasing the wear of the tarpaulin, and thus greatly reducing the service life of the tarpaulin.

[0004] 2. In the process of maintaining concrete pavements, after maintaining the concrete pavement for a period of time, it is necessary to rub and level its surface to make it flat. Traditionally, it is generally manually done by using tools in the later stage, which not only makes the operation steps cumbersome but also greatly reduces the work efficiency of maintaining the concrete pavement.

[0005] Therefore, in order to avoid affecting the service life of the tarpaulin and the work efficiency of maintaining the concrete pavement, the present invention provides a concrete pavement maintenance device and method for municipal road and bridge engineering. Summary of the Invention

Detailed implementation manners

[0036] To make the above - mentioned objects, features, and advantages of the present invention more obvious and understandable, the following will describe the detailed implementation manners of the present invention in conjunction with the accompanying drawings. Many specific details are set forth in the following description in order to fully understand the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0037] Refer to Figure 1 , a concrete pavement maintenance device for municipal road and bridge engineering, including a fixed vertical plate 1. At the upper position near the right end face of the fixed vertical plate 1, adjusting mechanisms 2 are symmetrically and fixedly arranged in the front and rear. A foldable tarpaulin 3 is fixedly arranged between the two groups of adjusting mechanisms 2 in the front and rear. A rectangular groove is opened at the middle position of the right end face of the fixed vertical plate 1 and below the adjusting mechanism 2. A detachable moving mechanism 4 is arranged in the rectangular groove. A fixing mechanism 5 for limiting the moving mechanism 4 is also arranged on the fixed vertical plate 1.

[0038] Refer to Figure 4 , at the bottom of the fixed vertical plate 1 near the four corners, self-locking universal wheels 11 are fixedly installed, and a fixed handle 12 for controlling the movement of the fixed vertical plate 1 is fixedly installed on the left side of the fixed vertical plate 1.

[0039] By the self-locking universal wheels 11 fixedly installed at the bottom of the fixed vertical plate 1 and the fixed handle 12 installed on the left side wall of the fixed vertical plate 1, it is possible to easily push the fixed handle 12 so that the fixed vertical plate 1 drives the device to move at any time and move to the position where it is necessary to maintain the concrete pavement for municipal road bridge projects. When the device is driven by the set self-locking universal wheels 11 to move to the side of the concrete pavement of the bridge project to be maintained, at this time, the set adjusting mechanism 2 is used to quickly open and extend the tarpaulin 3, and the tarpaulin 3 is used to cover and maintain the concrete pavement. After the tarpaulin 3 is opened by the set adjusting mechanism 2, the set moving mechanism 4 can support the extended tarpaulin 3 to prevent the tarpaulin 3 from collapsing and directly contacting the concrete pavement, thereby having a certain impact on the maintenance of the concrete pavement.

[0040] Refer to Figure 1 , Figure 2 and Figure 3 , the adjusting mechanism 2 includes two groups of C-shaped plates 21 symmetrically arranged before and after on the right end face of the fixed vertical plate 1 and placed opposite to each other at the openings for supporting and limiting after splicing. Except for the C-shaped plate 21 fixedly connected to the fixed vertical plate 1, at the bottom of the remaining C-shaped plates 21 near the left end, a receiving plate 22 is hinged by a pin shaft. The left and right adjacent C-shaped plates 21 are connected by a pre-tightening component 23, and a limiting plate 24 is fixedly installed between the front and rear two C-shaped plates 21 on the rightmost side. An adjusting component 25 for quickly controlling the opening and contraction of the tarpaulin 3 is also provided on the front and rear two C-shaped plates 21.

[0041] When the device is moved to the side of the concrete pavement for municipal road and bridge engineering, in the original state, the receiving plate 22 is perpendicular to the bottom of the U-shaped plate 21. At this time, the pre-clamping components 23 arranged between multiple adjacent U-shaped plates 21 on the left and right are first used for simple pre-clamping and limiting. After the clamping and limiting, the receiving plate 22 is rotated so that the receiving plate 22 perpendicular to the bottom of the U-shaped plate 21 rotates to a horizontal state, enabling the receiving plate 22 to support and limit the adjacent U-shaped plates 21 after docking, thereby increasing stability. Moreover, through the multiple spliceable U-shaped plates 21 arranged, when the device is not in use, it can be disassembled and then transported, avoiding occupying too much space, and thus enhancing the practicality of the device. When multiple U-shaped plates 21 are spliced, the awning 3 can be quickly unfolded and extended through the adjustment component 25 arranged, and the concrete pavement is covered and maintained by the awning 3, avoiding the problems of slow speed caused by the traditional method of unfolding and contracting the awning 3 by winding and having a certain impact on the maintenance of the concrete pavement.

[0042] Refer to Figure 4 , Figure 7 and Figure 8 , the pre-clamping component 23 includes two adjacent U-shaped plates 21 on the left and right. Installation grooves are formed on the right end faces of the U-shaped plates 21 near the left side, and clamping blocks 231 that are matched with the installation grooves are fixedly installed on the left end faces of the U-shaped plates 21 near the right side. A plurality of arc-shaped card slots are symmetrically arranged from left to right on the front and rear sides of the clamping block 231. A plurality of circular grooves corresponding to the arc-shaped card slots are symmetrically arranged on the front and rear sides in the installation grooves. Square blocks 233 are slidably connected in the circular grooves through return springs 232. Semi-arc-shaped grooves are formed at the ends of the square blocks 233 away from the return springs 232, and clamping beads 234 are rotatably arranged in the semi-arc-shaped grooves.

[0043] When the device is moved to the side of the concrete pavement for municipal road and bridge engineering, in the original state, at this time, multiple adjacent U-shaped plates 21 on the left and right are quickly docked, so that the clamping blocks 231 on the left end faces of the U-shaped plates 21 on the right side are quickly clamped into the installation grooves formed on the right end faces of the U-shaped plates 21 on the left side. At this time, the clamping beads 234 on the square blocks 233 arranged through the return springs 232 in the installation grooves can be quickly clamped into the arc-shaped card slots formed on the clamping blocks 231, and then the clamping blocks 231 can be simply pre-clamped.

[0044] Refer to Figure 2 and Figure 3, the adjusting assembly 25 includes a plurality of moving blocks 251 slidably arranged within two front and rear C-shaped plates 21. A motorized slider for controlling the movement of the moving blocks 251 is slidably arranged on the right side of the rightmost moving block 251 within the C-shaped plate 21. A rotating rod 252 is fixedly installed in the middle of each moving block 251. A round head plate 253 is rotatably arranged above the C-shaped plate 21 on the rotating rod 252. Each two adjacent round head plates 253 are hinged to each other by a pin shaft. A plurality of connecting plates 254 for fixing the tarpaulin 3 are fixedly installed below the C-shaped plate 21 on the rotating rod 252.

[0045] After quickly splicing between a plurality of adjacent C-shaped plates 21 on the left and right, the motorized slider is started at this time. The motorized slider causes the rightmost moving block 251 to drive the rotating rod 252 to move to the right. At this time, under the action of the rotating rod 252, the adjacent connected round head plates 253 are opened to each other, and a plurality of moving blocks 251 move within the chute formed between the C-shaped plates 21. Furthermore, the rotating rod 252 drives a plurality of connecting plates 254 to move. The plurality of connecting plates 254 cause the tarpaulin 3 to open and extend, and the tarpaulin 3 is used to cover and cure the concrete road surface, avoiding the problems of slow speed caused by the traditional method of rolling up and shrinking the tarpaulin 3 and having a certain impact on the curing of the concrete road surface.

[0046] Refer to Figure 4 and Figure 6 , the moving mechanism 4 includes a fixing plate 41 slidably arranged within a rectangular groove. A rectangular through groove is opened at a position near the left side of the top of the fixing plate 41. A supporting assembly 42 for supporting the tarpaulin 3 is arranged on the right end face of the fixing plate 41. A supporting plate 43 is fixedly installed in the middle of the right end face of the fixing plate 41. A sliding groove is opened at the bottom of the supporting plate 43. A threaded rod 44 is rotatably arranged within the sliding groove. The right end face of the threaded rod 44 passes through the supporting plate 43 and is fixedly connected to the output shaft of a forward and reverse motor fixedly installed through a motor base. A rectangular block 45 threadedly connected to the threaded rod 44 is also slidably arranged within the sliding groove. A moving assembly 46 for leveling the concrete road surface is arranged at the bottom of the rectangular block 45.

[0047] Refer to Figure 2 , the fixing mechanism 5 includes a fixing groove opened at the top of the fixing vertical plate 1 and communicating with the rectangular groove. A rectangular limiting block 51 for limiting and fixing the fixing plate 41 is slidably arranged within the fixing groove. A horizontal plate 52 is fixedly installed at the top of the rectangular limiting block 51. The horizontal plate 52 and the fixing vertical plate 1 are fixedly connected by a moving spring 53.

[0048] Before maintaining the concrete pavement for municipal road bridge projects, first use the horizontal plate 52 to drive the rectangular limit block 51 to move upward, so that the rectangular limit block 51 is out of the rectangular groove, and then the fixed plate 41 is slidably installed in the rectangular groove on the fixed vertical plate 1. After installation, the horizontal plate 52 is loosened. At this time, under the reaction force of the moving spring 53, the rectangular limit block 51 at the bottom of the horizontal plate 52 is just clamped into the rectangular through groove on the fixed plate 41, and then the fixed plate 41 is quickly limited and fixed. Through the detachable moving mechanism 4, when the device is not in use, it can also be disassembled and then transported to avoid occupying a large space that is not conducive to transportation. When the tarpaulin 3 are set During the process of opening and covering the concrete pavement for maintenance, the support assembly 42 is provided to support and limit the spread tarpaulin 3, so as to avoid the tarpaulin 3 from collapsing, which is not conducive to the maintenance of the concrete pavement. After covering the concrete pavement of the bridge project that needs to be maintained for a period of time, the provided moving assembly 46 is used to contact the concrete pavement that needs to be maintained. After the contact, the forward and reverse motors are started, so that the forward and reverse motors drive the threaded rod 44 to rotate. During the rotation of the threaded rod 44, the rectangular block 45 drives the moving assembly 46 to rub and smooth the concrete pavement back and forth under the limitation of the sliding groove to make it smooth. This rubbing and smoothing is repeated many times until the concrete is finally set.

[0049] See also Figure 4 and Figure 6 The support assembly 42 includes displacement grooves symmetrically opened in the front and rear of the right end face of the fixed plate 41, and movable plates 421 are slidably arranged in the displacement grooves. A bidirectional electric push rod for controlling the opening and contraction of the two movable plates 421 is fixedly installed in the middle of the fixed plate 41. The opposite surfaces of the front and rear movable plates 421 are opened with multiple sliding grooves from left to right, and a mounting block 422 is slidably arranged in the sliding groove. The mounting block 422 is hinged to one end of the swing plate 423 through a pin shaft, and the other end of the swing plate 423 is hinged to the side wall of the support plate 43 through a pin shaft.

[0050] When the tarpaulin 3 is opened and the concrete pavement is covered and maintained, the bidirectional electric push rods are started at the same time to move in opposite directions, so that the two movable plates 421 move in opposite directions. During the movement of the movable plates 421, the mounting block 422 drives the swing plate 423 to slide in the sliding groove, so that the multiple swing plates 423 are opened at the same time to support and limit the opened tarpaulin 3 to prevent the tarpaulin 3 from collapsing.

[0051] See also Figure 4 and Figure 5, the moving component 46 includes a structural plate 461 fixedly installed at the bottom of the rectangular block 45 through an electric telescopic rod. A moving groove is formed at the bottom of the structural plate 461. A sliding plate 463 is fixedly installed in the moving groove through a plurality of compression springs 462. An installation plate 464 with a trapezoidal structure having a small-diameter end downward is fixedly installed at the bottom of the sliding plate 463. A detachable horizontal trowel 465 for leveling the concrete road surface is further provided at the bottom of the installation plate 464.

[0052] After covering the concrete road surface for a period of time for the bridge engineering concrete road surface that needs to be maintained, start the electric telescopic rod. Use the electric telescopic rod to make the structural plate 461 drive the sliding plate 463 to move downward, and make the horizontal trowel 465 on the installation plate 464 at the bottom of the sliding plate 463 contact the concrete road surface that needs to be maintained. The compression springs 462 provided make the horizontal trowel 465 on the installation plate 464 at the bottom of the sliding plate 463 have a certain extrusion force on the concrete road surface, which is convenient for later rubbing and pressing. At this time, use the threaded rod 44 to make the rectangular block 45 drive the horizontal trowel 465 on the installation plate 464 to reciprocate left and right to rub and level the concrete road surface. During the process of reciprocating rubbing and leveling, the detachable horizontal trowel 465 provided can be replaced and cleaned in time to avoid impurities on the horizontal trowel 465 affecting the flatness of the concrete road surface.

[0055] S2. Concrete maintenance: After step S1 is completed, quickly dock between a plurality of adjacent C-shaped plates 21 on the left and right. After quick splicing, start the electric slider at this time. The electric slider makes the moving block 251 located on the rightmost side drive the rotating rod 252 to move to the right. At this time, under the action of the rotating rod 252, the adjacent round head plates 253 that are connected to each other are opened, and a plurality of moving blocks 251 move in the sliding grooves formed between the C-shaped plates 21, so that the rotating rod 252 drives a plurality of connecting plates 254 to move. The plurality of connecting plates 254 make the tarpaulin 3 open and extend, and use the tarpaulin 3 to cover and maintain the concrete road surface. At the same time, use the provided support assembly 42 to support and limit the opened tarpaulin 3 to avoid the situation of the tarpaulin 3 collapsing, which will have a certain impact on the maintenance of the concrete road surface.

[0056] S3. Concrete smoothing: After the completion of step S2, after covering the concrete pavement of the bridge project to be maintained for a period of time, start the electric telescopic rod. Use the electric telescopic rod to drive the sliding plate 463 downward by the structural plate 461, and make the horizontal trowel 465 on the mounting plate 464 at the bottom of the sliding plate 463 contact the concrete pavement to be maintained. At this time, use the threaded rod 44 to drive the rectangular block 45 to drive the horizontal trowel 465 on the mounting plate 464 to reciprocate left and right on the concrete pavement for rubbing and leveling, so that it is flat. Rub and level like this many times until the concrete reaches final setting.
