Description

Technical Field

[0001] The utility model relates to the technical field of filling construction, in particular to a filling construction device for highway engineering. Background Technique

[0002] Filling construction refers to the construction process of filling materials such as earthwork or stones into a designated area to form structures such as embankments, foundations or sites. In the processes of new highways, road widening, repair of subgrade settlement and filling sections in highway engineering, corresponding filling construction devices are often used for filling operations. Common filling construction devices include bulldozers, loaders, rollers, graders and pavers, etc.

[0003] The utility model with the existing authorization announcement number CN220813325U discloses a filling construction device for highway engineering. By making the mixing drum vibrate continuously, it can effectively prevent the phenomenon of material jamming in the mixing drum during transportation, and through the vibration of the mixing drum, the filling material attached to the inner wall of the mixing drum can be further reduced, further improving the utilization rate of the filling material in the mixing drum. And after filling, the device can be pushed to make the rolling column roll the filling material on the road surface, making the highway filling more flat.

[0004] Adopting the above technical solution, although it can effectively prevent the phenomenon of material jamming in the mixing drum during transportation and can also roll the filling material on the road surface, the above technical solution is inconvenient to control the rolling pressure of the filling material. And different scenarios have different requirements for the compaction degree of the filling material, lacking a flexible adjustment structure for adjusting the rolling pressure, resulting in a relatively limited application scenario for rolling the filling material.

[0005] Therefore, the technical personnel in the field provide a filling construction device for highway engineering to solve the problems raised in the above background technique. Content of the Utility Model

[0006] The purpose of the utility model is to provide a filling construction device for highway engineering to solve the problems raised in the above background technique.

[0007] To achieve the above purpose, the utility model provides the following technical solution:

[0008] A filling construction device for highway engineering, including a flatbed truck, and a rolling adjustment mechanism is arranged on the outer side of the flatbed truck;

[0009] The rolling adjustment mechanism includes a bracket, two rolling cylinders are rotatably connected to the inner wall of the bracket, two limiting guide rods are fixedly connected to the upper surface of the flatbed truck, several identical counterweight plates are arranged above the flatbed truck, a key controller is fixedly connected to the left side surface of the flatbed truck, a hydraulic rod is fixedly connected to the inner wall of the flatbed truck, a top rod is fixedly connected to the telescopic end of the hydraulic rod, a sleeve is fixedly connected to the upper surface of the bracket, and a pressure sensor is fixedly connected to the inner bottom wall of the sleeve.

[0010] As a further scheme of the utility model: the interior of each counterweight plate is slidably connected to the outer surface of the limiting guide rod, the bottom surfaces of two of the counterweight plates are in contact with the upper surface of the flatbed truck, the interior of the sleeve is slidably connected to the outer surface of the top rod, both the hydraulic rod and the pressure sensor are electrically connected to the key controller through wires, and four movable telescopic rods are fixedly connected to the inner top wall of the flatbed truck, and the telescopic end of each movable telescopic rod is fixedly connected to the upper surface of the bracket.

[0011] As a further scheme of the utility model: two connecting rods are fixedly connected to both the front surface and the back surface of the flatbed truck, and a pull ring is fixedly connected to the end of each connecting rod away from the flatbed truck.

[0012] As a further scheme of the utility model: a limiting cylinder is slidably connected to the outer surface of each limiting guide rod, and the bottom end of each limiting cylinder is in contact with the upper surface of the counterweight plate.

[0013] As a further scheme of the utility model: a hand-tightening bolt is threadedly connected to the inner wall of each limiting cylinder, and the end of each hand-tightening bolt close to the limiting guide rod is in contact with the outer surface of the limiting guide rod.

[0014] As a further scheme of the utility model: a reinforcing ring is fixedly connected to the outer surface of the telescopic end of the hydraulic rod, and the inner wall of the reinforcing ring is fixedly connected to the outer surface of the top rod.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] Through the mutual cooperation of a flatbed truck, a bracket, a pressure roller, a button controller, a limit guide rod, a counterweight disc, a hydraulic rod, a push rod, a sleeve and a pressure sensor, the bracket and the pressure roller themselves have a certain weight, which facilitates the rolling of the filling material with a certain gravity. The button controller can control the hydraulic rod to extend and retract different lengths, so that the push rod can slide inside the sleeve and then push against the pressure sensor, thereby adjusting the weight of the flatbed truck to increase the pressure of the pressure roller on the underlying filling material. A number of counterweight discs can be sleeved and slid on the limit guide rod, so that the weight that the hydraulic rod can adjust for the flatbed truck can be flexibly adjusted, playing a role in flexibly adjusting the rolling pressure, and avoiding the problem that the application scenario of rolling the filling material is relatively limited due to the lack of a flexible adjustment structure for the rolling pressure.

Detailed Embodiment

[0022] Please refer to Figures 1-4 , a filling construction device for highway engineering, including a flatbed truck 1. A rolling adjustment mechanism 2 is arranged on the outer side of the flatbed truck 1. The rolling adjustment mechanism 2 includes a bracket 201. Two pressure rollers 202 are rotatably connected to the inner wall of the bracket 201. Four movable telescopic rods 7 are fixedly connected to the inner top wall of the flatbed truck 1. The telescopic end of each movable telescopic rod 7 is fixedly connected to the upper surface of the bracket 201. By setting the movable telescopic rods 7, they can flexibly extend and retract, and after connecting the flatbed truck 1 and the bracket 201, the rolling and moving stability of the pressure rollers 202 in the bracket 201 is increased.

[0023] Two limit guide rods 204 are fixedly connected to the upper surface of the flatbed truck 1. A number of identical counterweight plates 205 are arranged above the flatbed truck 1. The inside of each counterweight plate 205 is slidably connected to the outer surface of the limit guide rod 204. The bottom surfaces of two of the counterweight plates 205 are in contact with the upper surface of the flatbed truck 1. Two connecting rods 3 are fixedly connected to both the front and the back of the flatbed truck 1. One end of each connecting rod 3 far from the flatbed truck 1 is fixedly connected with a pull ring 4. By providing the connecting rod 3, the pull ring 4 and the flatbed truck 1 can be connected. By providing the pull ring 4, the connection of an external dragging mechanism can be facilitated, and thus the external dragging mechanism can conveniently drag and operate the entire filling construction device.

[0024] A key controller 203 is fixedly connected to the left side surface of the flatbed truck 1. A hydraulic rod 206 is fixedly connected to the inner wall of the flatbed truck 1. A limit cylinder 5 is slidably connected to the outer surface of each limit guide rod 204. The bottom end of each limit cylinder 5 is in contact with the upper surface of the counterweight plate 205. By providing the limit cylinder 5, it can slide on the outer surface of the limit guide rod 204 and press on the uppermost counterweight plate 205, thereby cooperating with other structures to prevent the counterweight plate 205 from shaking.

[0025] A top rod 207 is fixedly connected to the telescopic end of the hydraulic rod 206. A sleeve 208 is fixedly connected to the upper surface of the bracket 201. The inside of the sleeve 208 is slidably connected to the outer surface of the top rod 207. A hand-tightening bolt 6 is threadedly connected to the inner wall of each limit cylinder 5. One end of each hand-tightening bolt 6 close to the limit guide rod 204 is in contact with the outer surface of the limit guide rod 204. By providing the hand-tightening bolt 6, it can be screwed by hand and travel along the inner wall of the limit cylinder 5 and press tightly against the outer surface of the limit guide rod 204, thereby fixing the position of the limit cylinder 5 relative to the limit guide rod 204, so that the limit cylinder 5 can effectively prevent the lower counterweight plate 205 from shaking.

[0026] A pressure sensor 209 is fixedly connected to the inner bottom wall of the sleeve 208. Both the hydraulic rod 206 and the pressure sensor 209 are electrically connected to the key controller 203 through wires. A reinforcing ring 8 is fixedly connected to the outer surface of the telescopic end of the hydraulic rod 206. The inner wall of the reinforcing ring 8 is fixedly connected to the outer surface of the top rod 207. By providing the reinforcing ring 8, the connection between the telescopic end of the hydraulic rod 206 and the top rod 207 can be strengthened, thereby preventing the two from breaking.

[0027] The working principle of the utility model is as follows: during use, an external dragging mechanism is connected to the flatbed truck 1 through the pull ring 4. Then, the external dragging mechanism drives the flatbed truck 1, enabling the entire filling construction device to be moved and used. In the initial state, the ejector rod 207 does not push against the pressure sensor 209. At this time, the rolling of the rolling roller 202 on the underlying filling material mainly relies on the self-weight of the bracket 201 and the rolling roller 202. When it is necessary to increase the rolling pressure of the rolling roller 202 on the underlying filling material, an appropriate amount of counterweight plates 205 are pre-sleeved on each limit guide rod 204. Then, the counterweight plates 205 are locked with the limit cylinder 5 and the hand-tightening bolt 6. Next, the required additional pressure to be applied to the rolling roller 202 is set through the key controller 203. Then, the key controller 203 will control the hydraulic rod 206 to automatically extend and make the ejector rod 207 push against the pressure sensor 209 until the pressure sensed by the pressure sensor 209 reaches the set value of the key controller 203, at which point the hydraulic rod 206 stops extending. During the process of the rolling roller 202 rolling the filling material, under the control of the key controller 203, the telescopic length of the hydraulic rod 206 will also change with the change in the pressure of the ejector rod 207 received by the pressure sensor 209, ultimately ensuring that the rolling roller 202 has a relatively stable rolling pressure on the underlying filling material, playing a role in being able to flexibly adjust the rolling pressure. The design of the entire highway engineering filling construction device effectively solves the problem that the application scenario of rolling the filling material is relatively limited due to the lack of a flexible adjustment structure for the rolling pressure.

[0028] The above is only the preferred specific implementation manner of the utility model, but the protection scope of the utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the utility model, according to the technical solution of the utility model and its inventive concept, makes equivalent substitutions or changes, and all should be covered within the protection scope of the utility model.
