Description

Technical Field

[0001] This utility model relates to the field of road construction technology, specifically a leveling device for hardening flood control roads. Background Technology

[0002] China is a country with many rivers and lakes. During the flood season, the water levels of these rivers rise rapidly and the flow is enormous, posing a serious flood threat to the surrounding areas. To cope with this natural disaster, it is necessary to build flood control roads on or along the dikes to enable rapid emergency transport during the flood season and reduce the losses caused by floods.

[0003] During the construction of existing flood control roads, the first step is to clear debris from the roadbed surface. Then, materials such as lime soil, asphalt, and concrete are used to pave the road according to actual needs. After paving, road rollers or leveling machines are used to level and compact the ground, thereby improving the efficiency and quality of road hardening and providing strong technical support for flood control road construction.

[0004] Road rollers or screeds typically use a single roller to level the ground. However, this roller usually has a fixed width, requiring multiple passes to ensure even leveling of surfaces wider than the roller. This slows down the leveling process and hinders the construction of flood control roads. To address these shortcomings, we propose a leveling device for flood control road hardening. Utility Model Content

[0005] The purpose of this utility model is to provide a leveling device for hardening flood control roads, which solves the problems mentioned in the background art.

[0006] This utility model is achieved through the following technical solution: a leveling device for hardening flood control roads, including a frame and a main roller rotatably mounted on one side of the frame. Two auxiliary rollers are slidably connected along the axial direction of the main roller on the side of the frame away from the main roller, and the two auxiliary rollers are slidably mounted relative to each other. When the two auxiliary rollers are far apart from each other, the distance between the outer surfaces of the two auxiliary rollers is greater than the width of the main roller.

[0007] Optionally, the frame has a mounting groove on the side near the auxiliary grinding wheel. The auxiliary grinding wheel is slidably connected to the frame via a mounting bracket. The auxiliary grinding wheel is rotatably connected to the inner side of the mounting bracket. A connecting plate is fixedly provided on the side of the mounting bracket near the frame. One end of the connecting plate extends into the mounting groove, and the connecting plate and the mounting groove are slidably connected.

[0008] Optionally, the inner bottom surface of the mounting groove is provided with a sliding groove, and a bidirectional cylinder is fixedly installed in the sliding groove. Both movable ends of the bidirectional cylinder are fixedly provided with sliders, and the upper surfaces of the two sliders are respectively fixedly connected to the lower surfaces of the two connecting plates.

[0009] Optionally, the auxiliary grinding wheel has an internal cavity structure, a stabilizing plate is fixedly provided on the inner side wall of the auxiliary grinding wheel, a hydraulic cylinder is fixedly provided on one side of the stabilizing plate, and an mounting plate is fixedly provided on the movable end of the hydraulic cylinder along the axial direction of the auxiliary grinding wheel. Several rollers are rolled on the mounting plate along the axial direction of the auxiliary grinding wheel.

[0010] Optionally, a through groove is provided on the side wall of the auxiliary grinding wheel for the roller to pass through; when the movable end of the hydraulic cylinder extends, the roller can pass through the through groove and extend to the outside of the auxiliary grinding wheel.

[0011] Optionally, a sealing strip is detachably connected to the through groove; when the sealing strip is installed in the through groove, the outer side of the sealing strip is flush with the outer side of the auxiliary grinding wheel.

[0012] Compared with the prior art, this utility model provides a leveling device for hardening flood control roads, which has the following beneficial effects:

[0013] 1. This utility model sets two relatively sliding auxiliary rollers on the frame, so that when the two auxiliary rollers are relatively far apart, they can cooperate with the main roller to increase the width of the total roller. This allows the leveling device to increase the leveling width of the device when the road width is greater than the width of the main roller, thereby reducing the number of back-and-forth leveling operations and improving leveling efficiency.

[0014] 2. This utility model uses an extendable roller inside the auxiliary grinding wheel to prevent the auxiliary grinding wheel from contacting the ground during relative sliding. Instead, the roller rolls on the ground, thereby reducing friction and making the sliding process of the auxiliary grinding wheel smoother. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1 - Figure 5 A leveling device for hardening flood control roads includes a frame 1 and a main roller 2 rotatably mounted on one side of the frame 1, so that the main roller 2 can roll on the road surface during the movement of the frame 1 on the road, thereby performing a rolling and leveling operation on the road surface.

[0023] Two auxiliary rollers 3 are slidably connected along the axial direction of the main roller 2 on the side of the frame 1 away from the main roller 2. The two auxiliary rollers 3 are arranged in a relative sliding configuration. When the two auxiliary rollers 3 are far apart from each other, the distance between the outer surfaces of the two auxiliary rollers 3 is greater than the width of the main roller 2. This allows the user to control the two auxiliary rollers 3 to move away from each other when the road width is greater than the width of the main roller 2, so that the auxiliary rollers 3 and the main roller 2 can cooperate to increase the total roller width, thereby reducing the number of times the device needs to level back and forth and improving the leveling efficiency.

[0024] Furthermore, a mounting groove 101 is provided on the side of the frame 1 near the auxiliary roller 3. The auxiliary roller 3 is slidably connected to the frame 1 via a mounting bracket 4. The auxiliary roller 3 is rotatably connected to the inner side of the mounting bracket 4, so that when the frame 1 moves, the auxiliary roller 3 will rotate on the mounting bracket 4, thereby leveling the road surface simultaneously with the main roller 2. A connecting plate 401 is fixedly provided on the side of the mounting bracket 4 near the frame 1. One end of the connecting plate 401 extends into the mounting groove 101, and the connecting plate 401 and the mounting groove 101 are slidably connected, so that when the connecting plate 401 slides in the mounting groove 101, it can drive the mounting bracket 4 to move together, thereby driving the auxiliary roller 3 to move together.

[0025] In this embodiment, a sliding groove 102 is provided on the inner bottom surface of the mounting groove 101. A bidirectional cylinder 5 is fixedly installed in the sliding groove 102. Slider 501 is fixedly installed on the two movable ends of the bidirectional cylinder 5. The upper surfaces of the two sliders 501 are respectively fixedly connected to the lower surfaces of the two connecting plates 401, so that when the bidirectional cylinder 5 controls the relative movement of the sliders 501 at the two movable ends, the sliders 501 can drive the connecting plates 401 to move together, thereby driving the mounting frame 4 and the auxiliary grinding wheel 3 to move together, so that the two auxiliary grinding wheels 3 move closer or further away from each other.

[0026] To ensure smoother movement of the auxiliary grinding wheel 3, this application employs an internal cavity structure. A stabilizing plate 6 is fixedly mounted on the inner wall of the auxiliary grinding wheel 3, with both its left and right sides fixedly connected to the inner wall of the auxiliary grinding wheel 3. This provides internal support to the auxiliary grinding wheel 3, increasing its stability. A hydraulic cylinder 7 is fixedly mounted on one side of the stabilizing plate 6. A mounting plate 701 is fixedly mounted on the movable end of the hydraulic cylinder 7 along the axial direction of the auxiliary grinding wheel 3. Several rollers 8 are rolled along the axial direction of the auxiliary grinding wheel 3 on the mounting plate 701. A through groove 301 is provided on the side wall of the auxiliary grinding wheel 3 for the rollers 8 to pass through. When the movable end of the hydraulic cylinder 7 extends, the rollers 8 can pass through the through groove 301 and extend to the outside of the auxiliary grinding wheel 3. This allows the hydraulic cylinder 7 to control the mounting plate 701 when the two auxiliary grinding wheels 3 need to move relative to each other. The plate 701 moves towards the through groove 301, and the mounting plate 701 drives several rollers 8 to move towards the through groove 301. Finally, the rollers 8 pass through the through groove 301 and extend a part to the outside of the auxiliary roller 3, so that the rollers 8 come into contact with the ground and support the auxiliary roller 3. When the auxiliary roller 3 moves relative to the ground, the rollers 8 roll along the axial direction of the auxiliary roller 3, which reduces the friction and makes the movement of the auxiliary roller 3 smoother. This avoids damage to the surface of the auxiliary roller 3 and affects the leveling effect of the road.

[0027] Furthermore, a sealing strip 302 is detachably connected inside the through groove 301; when the sealing strip 302 is installed inside the through groove 301, the outer side of the sealing strip 302 is flush with the outer side of the auxiliary roller 3, so that when the auxiliary roller 3 is used to level the ground, the sealing strip 302 can be installed inside the through groove 301, thereby preventing dust and dirt from entering the auxiliary roller 3 through the through groove 301.

[0028] In this embodiment, a wheel 103 is rotatably connected to the frame 1. The main roller 2 and the auxiliary roller 3 are located on the front and rear sides of the frame 1 away from the wheel 103, respectively. This allows the main roller 2 to first compact and level the road when the frame 1 moves to level the road. Then, the wheel 103 rolls onto the road surface, and finally, the auxiliary roller 3 further compacts and levels the road surface. This avoids leaving marks after the wheel 103 rolls, prevents it from affecting the road quality, and improves the flood control effect.

[0029] The working principle and usage process of this utility model are as follows: First, when leveling the flood control road, simply move the control frame 1 on the road. At this time, both the main roller 2 and the auxiliary roller 3 can compact and level the road.

[0030] When the road width is greater than the width of the main roller 2, the hydraulic cylinders 7 inside the two auxiliary rollers 3 can be activated first, driving the rollers 8 to move towards the through groove 301. This causes a portion of the rollers 8 to extend through the through groove 301 to the outside of the auxiliary rollers 3, thus supporting the auxiliary rollers 3. At this time, the slider 501 can be moved within the slide groove 102 by the bidirectional cylinder 5. The slider 501 drives the two connecting plates 401 to move relative to each other, causing the two mounting brackets 4 to move relative to each other. Ultimately, the two auxiliary rollers 3 move away from each other. The auxiliary rollers 3 and the main roller 2 work together to increase the width of the total roller, thereby adapting to wider roads, reducing the number of times the device levels the road, and improving the leveling efficiency.
