Description

Technical Field

[0001] This invention relates to the field of municipal roadbed maintenance technology, and specifically proposes a municipal roadbed maintenance construction equipment and process. Background Technology

[0002] The roadbed of municipal roads includes roadbed structure, shoulders, slopes, retaining walls, side ditches, drainage ditches, intercepting ditches, etc. This invention is for cleaning shoulders with hillsides. When it rains, mud and sand on the hillsides are easily washed onto the shoulders. In order to facilitate the maintenance of municipal roads, it is necessary to clean the shoulders.

[0003] However, the following problems still exist in the process of cleaning the road shoulders with hillsides: 1. In the process of cleaning the road shoulders with hillsides, it is inevitable to collide with the roadside guardrails, which will cause varying degrees of scratches on the surface of the guardrails and affect the cleaning effect of the road shoulders.

[0004] 2. In the process of cleaning the road shoulder with a hillside edge, the traditional method is to use a bulldozer to clean the mud and sand on the road surface horizontally.

Detailed Implementation

[0035] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0036] See Figure 1 A municipal roadbed maintenance construction equipment includes a holding box 1. The bottom of the holding box 1 is fixedly installed with self-locking casters 2. A push handle 3 is hinged to the middle of the front side of the holding box 1 through a pin. The middle part of the holding box 1 is hollow, and the bottom of the inner wall of the holding box 1 gradually slopes downward from left to right. A feed port is opened on the left side wall of the holding box 1 near the top. A cleaning mechanism 5 for cleaning the road shoulder is also provided at the upper end of the left side wall of the holding box 1. A material unloading mechanism 4 is provided on the right side wall of the holding box 1 near the bottom.

[0037] See Figure 1 and Figure 3The cleaning mechanism 5 includes an extension plate 50 fixedly installed on the upper end of the left side wall of a rectangular box. A threaded rod is slidably connected to the extension plate 50. A fixed plate 52 with an I-shaped structure is fixedly installed at the bottom of the threaded rod via a reciprocating assembly 51. A moving assembly 53 for controlling the up and down movement of the threaded rod is provided on the extension plate 50. Rectangular grooves are opened at the bottom of the front and rear horizontal sections of the fixed plate 52. Vertical plates 54 are slidably connected to the rectangular grooves via electric sliders. The opposite surfaces of the two vertical plates 54 are rotated. The rotating rods 55 are fixedly installed with an upward-opening C-shaped plate 56. The horizontal section of the C-shaped plate 56 slopes downward from right to left on the left side. Both the front and rear rotating rods 55 extend through the vertical plate 54 to the end away from the side wall of the C-shaped plate 56. The ends of the front and rear vertical plates 54 away from the C-shaped plate 56 are provided with a drive assembly 57 to control the movement of the C-shaped plate 56. A limit plate 58 is fixedly installed on the top of the C-shaped plate 56. The front and rear side walls of the C-shaped plate 56 away from the end of the container 1 are provided with a detachable buffer assembly 59.

[0038] In its initial state, the container 1 is first moved to the shoulder of the road where the mud and sand need to be cleared, using the push handle 3 installed on it. The self-locking casters 2, fixed to the bottom of the container 1, facilitate the movement of the equipment to the desired position. Once moved, the self-locking casters 2 provide simple fixation to prevent movement during the removal of mud and sand from the shoulder, thus avoiding any impact on the cleaning effect. After the self-locking casters 2 have limited its position, the moving component 53 then reciprocates the bottom of the threaded rod. Component 51 drives the fixed plate 52 to move downwards, causing the vertical plate 54 and rotating rod 55 on the fixed plate 52 to move the chamfered plate 56 downwards, making the horizontal section of the chamfered plate 56 parallel to the road shoulder. At this time, through the set drive component 57, the rotating rod 55 drives the chamfered plate 56 to rotate and tilt to the lower left, so that the inclined surface on the left side of the horizontal section of the chamfered plate 56 first contacts the road shoulder. When the road surface has a slope, the tilt angle of the chamfered plate 56 can be adjusted at any time, so that the left side of the horizontal section of the chamfered plate 56 is always in contact with the road shoulder, thereby facilitating better removal of mud and sand on the road shoulder. This method of removal and cleaning avoids the incomplete cleaning that often occurs with traditional direct horizontal removal. When the left side of the horizontal section of the chamfered slab 56 contacts the road shoulder, the electric slider causes the vertical plate 54 to simultaneously move the chamfered slab 56 to the left, thus cleaning the mud and sand on the road shoulder. During this cleaning process, the reciprocating component 51 adjusts and corrects the position of the chamfered slab 56, preventing it from colliding with the guardrail on the road shoulder. The buffer component 59 provides cushioning and protection, preventing the chamfered slab 56 from directly impacting the road shoulder. The impact caused damage to the guardrail post on the road shoulder. After cleaning, the drive component 57 returned the convex plate 56 to its upright position, and then proceeded to the next step of shoveling and cleaning. When the convex plate 56 was full, the set moving component 53 moved the convex plate 56 upward to the position of the feed inlet. At this time, the electric slider was activated so that the bottom of the horizontal section of the convex plate 56 on the vertical plate 54 was located inside the feed inlet. The set drive component 57 was used again to tilt the horizontal section of the convex plate 56 to the lower right, so that the shoveled mud and sand were poured into the holding box 1, and the holding box 1 was used to collect the mud and sand.

[0039] See Figure 1 and Figure 2 The moving component 53 includes a forward and reverse motor fixedly installed on the top of the protruding plate 50. The output shaft of the forward and reverse motor is fixedly installed with a drive gear 531. A driven gear 532 that meshes with the drive gear 531 is threadedly connected to the threaded rod. An annular limiting groove is provided at the bottom of the driven gear 532. Two fixed rods 533 that are slidably connected in the annular limiting groove are fixedly installed on the protruding plate 50. The bottom of the protruding plate 50 and the structural plate 511 are fixedly connected by a No. 3 spring rod 534.

[0040] After the device is limited by the self-locking universal wheel 2, the forward and reverse motor is started to rotate forward, so that the driving gear 531 drives the driven gear 532 to rotate. At this time, under the limitation of the fixed rod 533 and the third spring rod 534, the reciprocating component 51 at the bottom of the threaded rod drives the fixed plate 52 to move downward, and the C-shaped plate 56 set on the fixed plate 52 is used to clean the mud and sand on the road shoulder. When the C-shaped plate 56 is full of mud and sand, the forward and reverse motor is started to reverse, so that the reciprocating component 51 at the bottom of the threaded rod drives the fixed plate 52 to move upward, thereby driving the C-shaped plate 56 set on the fixed plate 52 to the position of the feed inlet.

[0041] See Figure 1 and Figure 4 The reciprocating assembly 51 includes a structural plate 511 fixedly installed at the bottom of the threaded rod. A displacement groove is provided at the bottom of the structural plate 511. A sliding block 512 is slidably arranged in the middle of the displacement groove. The front and rear side walls of the sliding block 512 and the displacement groove are fixedly connected by a second spring rod 513. The bottom of the sliding block 512 is fixedly connected to the middle position of the top of the fixed plate 52.

[0042] When cleaning the road shoulder using the swivel plate 56, the sliding block 512, which is slidably set in the displacement groove at the top of the fixed plate 52, can leave a certain space allowance for the fixed plate 52 to move the swivel plate 56 to a certain limit, thereby adjusting and correcting the position of the swivel plate 56 and preventing the swivel plate 56 from hitting the guardrail on the road shoulder.

[0043] See Figure 4 and Figure 5 The drive assembly 57 includes a transmission gear 571 fixedly mounted on the rotating rod 55, an extension plate 572 fixedly mounted near the top of the vertical plate 54 at the end away from the side wall of the U-shaped plate 56, and a rack plate 574 fixedly mounted on the bottom of the extension plate 572 via an electric push rod 573. The rack plate 574 and the transmission gear 571 mesh and drive each other.

[0044] When the vertical plate 54 and the rotating rod 55 drive the chamfered plate 56 downwards, making the horizontal section of the chamfered plate 56 parallel to the road shoulder, the electric push rod 573 is activated to drive the rack plate 574 downwards. This causes the rack plate 574 to drive the transmission gear 571 to rotate. The transmission gear 571 then causes the rotating rod 55 to rotate the chamfered plate 56 by a certain angle, causing the chamfered plate 56 to rotate and tilt downwards to the left. Consequently, the inclined surface on the left side of the horizontal section of the chamfered plate 56 first contacts the road shoulder, and then... After the mud and sand on the road shoulder are cleaned, when the electric slider makes the bottom of the horizontal section of the C-shaped plate 56 on the vertical plate 54 inside the feed inlet, the electric push rod 573 is activated to drive the rack plate 574 to move upward, so that the rack plate 574 drives the transmission gear 571 to rotate. The transmission gear 571 causes the rotating rod 55 to drive the C-shaped plate 56 to rotate at a certain angle, so that the C-shaped plate 56 rotates to tilt to the right and downward, making it easier to pour the removed mud and sand into the holding box 1.

[0045] See Figure 6 and Figure 7 The bottom of the limiting plate 58 is provided with an isolation frame 581 and a limiting frame 585 to prevent mud and sand from falling in, located near the left and right sides of the chamfered plate 56, respectively. The isolation frame 581 includes a movable plate 582 that is hinged to the bottom of the limiting plate 58 by a pin. The right side wall of the movable plate 582 is fixedly connected to the limiting plate 58 by a tension spring 583 near the hinge. The horizontal end of the chamfered plate 56 is symmetrically fixedly installed with a stop block 584 to limit the movable plate 582 on the left side. The limiting frame 585 includes a swing plate 586 that is hinged to the bottom of the limiting plate 58 by a pin. The left side wall of the swing plate 586 is fixedly connected to the limiting plate 58 by a movable spring 587 near the hinge. The horizontal end of the chamfered plate 56 is provided with an installation groove on the right side of the swing plate 586. A limiting block 588 to limit the swing plate 586 is slidably connected in the installation groove by an electric telescopic rod.

[0046] In the initial state, the swing plate 586 is limited by the set limit block 588. During the process of cleaning mud and sand by the C-shaped plate 56, the mud and sand push the moving plate 582 to compress and stretch the spring 583, so that the mud and sand can smoothly enter the C-shaped plate 56. The set limit block 588 limits the swing plate 586 to prevent mud and sand from falling. After the electric slider makes the bottom of the horizontal section of the C-shaped plate 56 on the vertical plate 54 located in the feed port, the electric telescopic rod is activated so that the limit block 588 no longer limits the swing plate 586. When the drive component 57 makes the C-shaped plate 56 tilt to the lower right, the gravity of the mud and sand pushes the swing plate 586 to open, so that the mud and sand can smoothly fall into the holding box 1.

[0047] See Figure 6 and Figure 8The buffer assembly 59 includes T-shaped grooves opened at the top of the front and rear vertical sections of the inverted plate 56. A T-shaped mounting plate 591 is vertically slidably engaged in the T-shaped groove. A rectangular block 592 is fixedly installed at the end of the vertical section of the mounting plate 591 away from the side wall of the inverted plate 56. An arc plate 593 is hinged to the end of the rectangular block 592 away from the mounting plate 591 and near the left side by a pin. The arc plate 593 and the rectangular block 592 are fixedly connected by multiple buffer springs 594. A removable rubber anti-collision layer is provided at the end of the arc plate 593 away from the buffer springs 594.

[0048] The sliding mounting plate 591 allows for quick disassembly and replacement of the buffer assembly 59. The buffer spring 594 provides cushioning protection, and the rubber anti-collision layer on the curved plate 593 prevents the curved plate 56 from directly impacting the guardrail post on the road shoulder and causing damage.

[0049] See Figure 3 The feeding mechanism 4 includes a rectangular feeding channel opened at the lower end of the right side wall of the holding box 1, and a displacement channel opened above the feeding channel on the right side wall of the holding box 1. A toggle plate 42 is slidably connected in the displacement channel by multiple No. 1 spring rods 41. A rectangular baffle 43 is fixedly installed at the bottom of the toggle plate 42 to close the feeding channel.

[0050] When the container 1 is filled with mud and sand, the movable actuating plate 42 is moved upward, causing the actuating plate 42 to drive the rectangular baffle 43 upward, thereby opening the discharge channel and facilitating the rapid discharge of the collected mud and sand. After the discharge is completed, the actuating plate 42 is released, and the rectangular baffle 43 returns to its original position under the action of the first spring rod 41, thus closing the discharge channel.

[0051] This invention also employs a municipal roadbed maintenance construction process, the specific construction process including the following steps:

[0052] S1. Mobile device: First, the container 1 is moved to the shoulder of the road where the mud and sand need to be cleared by pushing the handle 3 set on the container 1.

[0053] S2. Cleaning Mechanism 5 Cleaning: After step S1 is completed, the moving component 53 causes the reciprocating component 51 at the bottom of the threaded rod to move the fixed plate 52 downwards. This causes the vertical plate 54 and rotating rod 55 on the fixed plate 52 to move the chamfered plate 56 downwards, making the horizontal section of the chamfered plate 56 parallel to the road shoulder. At this time, the driving component 57 causes the rotating rod 55 to rotate the chamfered plate 56 to tilt to the lower left. As a result, the inclined surface on the left side of the horizontal section of the chamfered plate 56 first contacts the road shoulder. When it encounters road surface with... When the slope is steep, the tilt angle of the slab 56 can be adjusted at any time, so that the left side of the horizontal section of the slab 56 is always in contact with the shoulder. After the left side of the horizontal section of the slab 56 is in contact with the shoulder, the electric slider is used to make the vertical plate 54 move the slab 56 to the left, thereby clearing the mud and sand on the shoulder. During the process of the slab 56 clearing the mud and sand, the buffer component 59 can play a buffering and protective role, preventing the slab 56 from directly hitting the guardrail post on the shoulder and causing damage.

[0054] S3. Collecting mud and sand: After step S2 is completed, when the convex plate 56 is full, the moving component 53 is used to move the convex plate 56 upward to the feed inlet. At this time, the electric slider is activated so that the bottom of the horizontal section of the convex plate 56 on the vertical plate 54 is inside the feed inlet. The driving component 57 is used again to tilt the horizontal section of the convex plate 56 to the lower right so that the mud and sand after being removed are poured into the holding box 1. The holding box 1 is used to collect the mud and sand.

[0055] S4: Sand and mud discharge: After step S3 is completed, when the container 1 is full of sand and mud, move the actuating plate 42 upward, so that the actuating plate 42 drives the rectangular baffle 43 upward, so that the discharge channel is opened, and the collected sand and mud can be discharged quickly.
