As a "joint component" of municipal roads, the construction quality of manhole covers directly affects driving comfort, safety and road service life.

[0003] For the invention patent application with the publication number of CN118481008B, the existing municipal road construction equipment includes a mobile frame. The mobile frame includes a mobile plate. A horizontally arranged water spray pipe is installed at the bottom of the mobile plate. A plurality of nozzles are installed at the bottom of the water spray pipe. The plurality of nozzles are equidistantly arranged along the width direction of the mobile plate. A water tank is installed on the top surface of the mobile plate. A water pump is installed at the bottom of the water tank.

A conveying roller and a pressing roller for conveying the moisture preservation film are rotatably installed on the bottom surface of the mobile plate. A flattening wheel is rotatably installed on one side of the mobile plate away from the mounting roller. The outer peripheral surface of the flattening wheel can be attached to the top surface of the moisture preservation film; This kind of municipal road construction equipment can make the moisture preservation film closely adhere to the surface of the concrete road, thereby reducing the evaporation rate of water and promoting the full curing and strength development of concrete.

[0004] During the laying process of drainage manhole covers on existing municipal roads, it is necessary to install the outer frame of the manhole cover. Since a position for installing the manhole cover is reserved during road paving, it is inevitable that the edges form a non-uniform flatness during the construction process, which affects the smooth installation of the outer frame of the manhole cover. And because the weight of the outer frame of the manhole cover is generally heavy, the existing installation method generally involves manual trimming and then manual alignment and installation, and after the installation is completed, it is necessary to fill the gaps with concrete. This installation method greatly increases the complexity and labor intensity of the installation.

[0005] Therefore, it is very necessary to invent a municipal road construction device and a construction method thereof to solve the above problems. Summary of the Invention

Detailed implementation manners

[0020] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further introduced in detail below in conjunction with the accompanying drawings.

[0021] The present invention provides a municipal road construction device as shown in Figures 1-11 Figure 10, which includes a carrier frame 001. Inside the carrier frame 001, there is a carrier table 101. Above the carrier table 101, a hydraulic rod 102 is installed between the upper part of the inner wall of the carrier frame 001. Below the carrier table 101, there is a ring frame 103. A plurality of groups of connecting frames 104 are installed between the ring frame 103 and the carrier table 101 in an annular distribution; The hydraulic rod 102 can push the carrier frame 001 to move, thereby driving the ring frame 103 to move synchronously.

[0022] The adjusting assembly 002 provided below the carrier table 101 includes a bidirectional screw 201. The bidirectional screw 201 is rotatably connected below the carrier table 101. Symmetrically threaded on the bidirectional screw 201 are internal thread blocks 203. Symmetrically installed below the carrier table 101 are limiting rods 202, and the limiting rods 202 penetrate through the edges of the two internal thread blocks 203. Above the carrier table 101, a servo motor one 208 is installed, and the output end of the servo motor one 208 is axially connected to the bidirectional screw 201; The servo motor one 208 can drive the bidirectional screw 201 to rotate, so that the two internal thread blocks 203 move towards each other.

[0023] The fixing component 003 disposed below the carrying platform 101 includes a fixing plate 303. A unidirectional screw 304 is screwed through the fixing plate 303. Above the unidirectional screw 304, a first gear 305 is installed. On one side of the fixing plate 303 away from the unidirectional screw 304, a fixing rod 306 is connected through a limit. A first spring 307 is sleeved on the fixing rod 306, and both sides of the first spring 307 are respectively in contact with the fixing plate 303 and the lower part of the fixing rod 306. The first gear 305 can drive the unidirectional screw 304 to rotate, so that the fixing plate 303 moves downward, and pushes the fixing rod 306 to move downward to fit with the outer frame of the manhole cover, thereby squeezing the first spring 307. And the first spring 307 can make the fixing rod 306 reset after the fixing plate 303 resets.

[0024] The driving component 004 disposed in the annular frame 103 includes an annular groove 401. The annular groove 401 is opened on the inner wall of the annular frame 103. A rotating ring 402 is arranged in the annular frame 103. A positioning ring 403 is sleeved and fixed on the rotating ring 402. The positioning ring 403 is slidably connected with the annular groove 401. Through the cooperation of the positioning ring 403 and the annular groove 401, the rotating ring 402 can rotate stably in the annular frame 103.

[0025] The power component 005 disposed outside the annular frame 103 includes positioning holes 502. The positioning holes 502 are symmetrically opened on the outside of the annular frame 103. Symmetrically arranged connecting frames 503 are arranged on the outside of the annular frame 103. Positioning rods 504 are sequentially installed on the inner walls of the two groups of connecting frames 503, and the positioning rods 504 are connected through the corresponding positioning holes 502.

[0026] Through the cooperation of the positioning rods 504 and the positioning holes 502, the connecting frames 503 can reciprocate outside the annular frame 103.

[0027] Further, in the above structure, the adjusting component 002 further includes a first connecting rod 204. The first connecting rods 204 are annularly distributed and rotatably connected to one side of the upper internal thread block 203. One side of each group of first connecting rods 204 away from the internal thread block 203 is rotatably connected to an L-shaped fixing seat 205.

[0028] Through the up and down movement of the internal thread block 203, the first connecting rod 204 can drive the L-shaped fixing seat 205 to move horizontally.

[0029] Further, in the above structure, rubber pads 206 are installed on the inner walls of the L-shaped fixing seats 205. One side of the lower internal thread block 203 is annularly distributed and rotatably connected with second connecting rods 207, and the second connecting rods 207 of each group are rotatably connected to the bottom of the corresponding L-shaped fixing seat 205.

[0030] Through the cooperation of the second connecting rod 207, the L-shaped fixing seat 205 can move horizontally, so as to realize corresponding adjustment according to the inner wall size of the manhole cover outer frame, and the first rubber pad 206 can ensure soft fitting between the L-shaped fixing seat 205 and the inner wall of the manhole cover outer frame, avoiding damage to the inner wall of the manhole cover outer frame.

[0031] Further, in the above structure, the fixing component 003 further includes a guiding hole 301, the guiding holes 301 are symmetrically arranged above the L-shaped fixing seat 205, guiding rods 302 are symmetrically installed below the fixing plate 303, and the guiding rods 302 are connected through the corresponding guiding holes 301. A second rubber pad 308 is installed below the inner wall of the L-shaped fixing seat 205, and the second rubber pad 308 and the fixing rod 306 are arranged opposite to each other up and down.

[0032] Through the cooperation of the guiding hole 301 and the guiding rod 302, the fixing plate 303 can move up and down stably, and the second rubber pad 308 can ensure that when the L-shaped fixing seat 205 contacts the lower part of the manhole cover outer frame, damage to the manhole cover outer frame is avoided.

[0033] Further, in the above structure, the driving component 004 further includes an arc-shaped internal gear plate 405. Push rods 404 are sequentially installed on the outer side of the arc-shaped internal gear plate 405, and the push rods 404 are connected through the inner wall of the rotating ring 402. And a plurality of arc-shaped internal gear plates 405 are annularly distributed in the rotating ring 402, and the arc-shaped internal gear plate 405 meshes with the first gear 305.

[0034] Through the push rod 404, the effect of the arc-shaped internal gear plate 405 moving in the rotating ring 402 can be realized. And because the arc-shaped internal gear plate 405 meshes with the first gear 305, while the arc-shaped internal gear plate 405 drives the first gear 305 to rotate, it can be realized that while the first gear 305 follows the adjustment of the L-shaped fixing seat 205, the size of the arc-shaped internal gear plate 405 is adjusted correspondingly.

[0035] Further, in the above structure, rubber strips 407 are installed between the arc-shaped internal gear plates 405, and a second spring 406 is sleeved on each push rod 404, and both sides of the second spring 406 are respectively attached to the arc-shaped internal gear plate 405 and the inner wall of the rotating ring 402.

[0036] Through the arrangement of the rubber strip 407, when the first gear 305 just stops at the position between two arc-shaped internal gear plates 405, the problem that it is difficult for the first gear 305 to drive the arc-shaped internal gear plate 405 to make corresponding adjustment when adjusting the position is avoided, and the second spring 406 can ensure that when the position adjustment of the first gear 305 decreases, the first gear 305 and the arc-shaped internal gear plate 405 are always meshed.

[0037] Further, in the above structure, the power assembly 005 further includes a docking rod 505. The docking rod 505 is sequentially installed inside the connecting frame 503, and the docking rod 505 is fixedly connected to a push rod 404 on one side of the corresponding arc-shaped internal tooth plate 405. A small breaker 506 is installed below one group of connecting frames 503, and a concrete conveyor 507 is installed below the other group of connecting frames 503.

[0038] By adjusting the position of the arc-shaped internal tooth plate 405, the position of the connecting frame 503 can be changed, so as to correspondingly adjust the positions of the small breaker 506 and the concrete conveyor 507, so as to realize the corresponding position adjustment according to the manhole cover outer frames of different sizes.

[0039] Further, in the above structure, a connecting seat 508 is installed between the connecting frames 104. An external tooth ring 501 is sleeved and fixed outside the rotating ring 402. A second servo motor 509 is installed above the connecting seat 508. The output end of the second servo motor 509 is axially connected with a second gear 510, and the second gear 510 meshes with the external tooth ring 501.

[0040] The second servo motor 509 can drive the second gear 510 to rotate, and through the external tooth ring 501, the second servo motor 509 can drive the entire rotating ring 402 to rotate, so as to realize the arc-shaped internal tooth plate 405 driving the first gear 305 to rotate, realize the downward movement and fixation of the fixed plate 303, and the small breaker 506 and the concrete conveyor 507 can also perform rotary breaking and trimming and concrete filling through this action.

[0041] As Figures 1-11 shown, by the rotation of the first servo motor 208, the bidirectional screw rod 201 drives the internal thread blocks 203 to move relative to each other, so that the L-shaped fixing seat 205 is adjusted to a position with the same size as the manhole cover outer frame to be installed. At the same time, the connecting frame 503 will move to the corresponding position under the action of the docking rod 505. At this time, the second servo motor 509 drives the second gear 510 to rotate, so that the second gear 510 drives the rotating ring 402 to rotate through the external tooth ring 501, so that the connecting frame 503 drives the small breaker 506 to move. At this time, the manhole cover outer frame is not fixed, and the small breaker 506 can perform a full-circle breaking and trimming operation through reciprocating rotation.

[0042] When the operation is completed, the position of the L-shaped fixing seat 205 can be adjusted to fit the inner wall of the manhole cover outer frame. At this time, the arc-shaped internal tooth plate 405 drives the first gear 305 to rotate, so that the unidirectional screw rod 304 drives the fixed plate 303 to move downward, realizing the fixation of the fixed plate 303 to the manhole cover outer frame, and through the downward movement of the hydraulic rod 102, the manhole cover outer frame is placed into the drainage inlet.

[0043] Meanwhile, in the same way, the concrete transporter 507 is rotated. While the concrete transporter 507 is rotating, the fixing plate 303 can just release the manhole cover outer frame. Meanwhile, the first servo motor 208 is started to disengage the L-shaped fixing seat 205 from the manhole cover outer frame, and the concrete pouring is completed. Moreover, the disassembly of the manhole cover outer frame can be realized through the demolition of the small demolition device 506, thus facilitating the later replacement. Through this structure, the automatic installation or disassembly of the manhole cover outer frame can be realized, and it can be automatically adjusted according to different manhole cover installation dimensions, greatly improving the installation efficiency and reducing the labor intensity of construction workers.

[0044] Only some exemplary embodiments of the present invention have been described by way of illustration above. Undoubtedly, for those of ordinary skill in the art, the described embodiments can be modified in various different ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the protection scope of the claims of the present invention.

A method for constructing a municipal road, comprising a municipal road construction device according to any one of claims 1-8, characterized in that: The processing steps are as follows: S1: Drive the bidirectional screw rod (201) to rotate through the first servo motor (208), so that the bidirectional screw rod (201) drives the internally threaded blocks (203) to move towards each other, thereby enabling multiple groups of L-shaped fixing bases (205) to move outwards, so that the L-shaped fixing bases (205) are attached to the inner wall of the manhole cover outer frame. S2: Drive the second gear (510) to rotate through the second servo motor (509), so that the external gear ring (501) drives the rotating ring (402) to rotate, so that the arc-shaped internal gear plate (405) drives the unidirectional screw rod (304) to rotate through the first gear (305), so that the fixing plate (303) fixes the manhole cover outer frame. S3: After using the small demolition tool (506) to demolish and trim the periphery of the drainage well, at this time, move the manhole cover outer frame downward through the hydraulic rod (102), and pour concrete between the drainage well and the manhole cover outer frame through the concrete conveyor (507) to complete the installation of the manhole cover outer frame.
