Therefore, they cannot be understood as limitations on the present invention.
[0019] The technical solution is a concrete leveler provided with a telescopic extension mechanism, which is added to the concrete leveler and can adjust the leveling range at any time according to the gradual change of the width of the road.
[0020] like Figure 1 , Figure 5 , Figure 7As shown, the concrete leveling machine includes a main truss 1, a lifting mechanism, a traveling mechanism, a main leveling mechanism and a telescopic extension mechanism. Among them, the main truss 1 is the main structure, and various functional module components are arranged on the main truss 1. The two ends of the main truss 1 are arranged on the traveling mechanism through the lifting mechanism. The traveling mechanism drives the whole machine to move longitudinally. The lifting mechanism adjusts the height of the main truss 1. The main leveling mechanism is arranged at the lower end of the main truss 1, and the main leveling mechanism is used to level the main road surface. A telescopic extension mechanism is arranged at the end of the main truss 1, and the telescopic extension mechanism includes a vibrating screed plate 2, so that the road surface in the area outside the main truss 1 can be vibrated and leveled. The telescopic extension mechanism can be adjusted telescopically, so that the road surface with a gradually changing width can be vibrated and leveled.
[0021] In a specific implementation, a telescopic extension mechanism is provided at one end of the main truss 1 , or at both ends of the main truss 1 , according to needs.
[0022] like Figure 2 , Figure 3 , Figure 4 As shown, specifically, the telescopic extension mechanism includes a telescopic component, a lifting component and a vibrating screed plate 2. The telescopic component can be extended and recovered, and the telescopic component has a fixed end and a telescopic end; the fixed end of the telescopic component is fixedly installed at the ends of both ends of the main truss 1, and the outermost end of the telescopic end of the telescopic component is fixedly provided with a lifting component. The vibrating screed plate 2 is provided at the lower end of the lifting component through a rotating component 10. The telescopic component can drive the lifting component, the rotating component 10 and the vibrating screed plate to move together, so as to extend and recover the width.
[0023] The telescopic assembly is arranged horizontally, and the lifting assembly is arranged vertically. The fixed end of the lifting assembly is fixedly mounted on the outer end of the telescopic assembly, and the lifting end of the lifting assembly faces downward. A rotating assembly 10 driven by a motor is arranged at the lower end of the lifting assembly. A vibrating screed plate 2 is fixedly mounted at the lower end of the rotating assembly. The rotating assembly 10 can drive the vibrating screed plate 2 to rotate, thereby adjusting the working direction in accordance with the extension or retraction process of the telescopic assembly. The rotating assembly is a purchased component. For example, a rotary drive member, a hydraulic turntable, etc., can meet the requirements of use.
[0024] In specific implementation, the telescopic assembly is usually a structure using a multi-stage sleeve and a cylinder. The multi-stage sleeve plays the role of telescopic bearing, and the cylinder plays the role of telescopic driving. Specifically, the telescopic assembly includes a set of multi-stage telescopic cylinders and a plurality of telescopic cylinders 4 driving the telescopic cylinders. The telescopic cylinders 3 are generally set in multiple stages, that is, multiple telescopic cylinders 3 are set in sequence. A telescopic cylinder 4 is arranged between two adjacent telescopic cylinders 3, and the telescopic cylinder 4 is used to drive the telescopic cylinder 3 to move relative to the telescopic cylinder of the previous stage. The telescopic cylinder 4 has a cylinder barrel and a telescopic rod. The cylinder barrel of the telescopic cylinder 4 is fixed on the outer wall of the telescopic cylinder 3 of a certain level, and the outermost end of the telescopic rod of the telescopic cylinder 4 is fixedly connected to the outer wall of the telescopic cylinder 3 of the next level. In this way, the telescopic cylinder 3 of the next level can be pushed out of the telescopic cylinder 3 of the current level. Generally, a three-stage telescopic cylinder can be used, and a two-stage telescopic cylinder, a four-stage telescopic cylinder, or a five-stage telescopic cylinder can also be set. The telescopic assembly of this structure has a high load-bearing capacity, and each telescopic cylinder can be controlled separately, which is easier to control as a whole.
[0025] like Figure 2 , Figure 3 As shown, the lifting assembly also uses a multi-stage sleeve with a cylinder structure, which is similar to the structure of the telescopic assembly mentioned above. Specifically, the lifting assembly includes a set of multi-stage lifting cylinders and a plurality of lifting cylinders 6 that drive the lifting cylinders 5. The lifting cylinders 5 have multiple levels, that is, multiple lifting cylinders 5 are set in sequence. A lifting cylinder 6 is arranged between two adjacent lifting cylinders 5, and the lifting cylinder 6 is used to drive the lifting cylinder 5 to rise and fall relative to the lifting cylinder 5 of the previous level. The lifting cylinder 6 has a cylinder and a moving rod. The cylinder of the lifting cylinder 6 is fixed on the outer wall of a certain level of the lifting cylinder 5, and the moving rod of the lifting cylinder 6 is fixedly connected to the outer wall of the lifting cylinder 5 of the next level. In this way, the lifting cylinder 5 of the next level can be pushed out of the lifting cylinder 5 of the current level. Generally, a two-stage lifting cylinder can be used, and a three-stage lifting cylinder can also be set. The lifting assembly of this structure has a high carrying capacity, and each lifting cylinder 6 can be controlled separately, which is easier to operate as a whole.
[0026] When a two-stage lifting cylinder lifting assembly is provided, the lifting assembly includes two-stage lifting cylinders 6 and a lifting oil cylinder 7 for driving the lifting cylinders. The first-stage lifting cylinder 6 is fixed to the outer end of the telescopic assembly, and the second-stage lifting cylinder 6 is sleeved inside the first-stage lifting cylinder 6. The cylinder of the lifting oil cylinder 7 is fixed to the outer wall of the first-stage lifting cylinder 6, and the outermost end of the moving rod of the lifting oil cylinder 7 is fixedly connected to the outer wall of the second-stage lifting cylinder 6.
[0027] The above telescopic cylinder and lifting cylinder are sleeve structure components used, which are usually rectangular cylinder structures.
[0028] like Figure 1 , Figure 6As shown, the main truss 1 of the concrete leveling machine is provided with a main leveling mechanism at the lower end to perform leveling construction on the main road surface. The main leveling mechanism includes a main leveling plate 7 and a vibrating push plate 8 fixedly arranged at the front end of the main leveling plate 7. Usually, the main integral plate 7 and the vibrating push plate 8 are set as an integrated structure; and a vibrator is set on the main leveling plate 7. By setting the vibrator, the main leveling plate 7 can be vibrated to perform slurry leveling. The vibrating push plate 8 is vertically arranged relative to the main leveling plate 7, similar to the push bucket of a bulldozer. The vibrating push plate 8 can play the role of pushing away excess materials to prevent material accumulation. The vibrating push plate 8 is an integrated structure with the main leveling plate 7, and the vibrating push plate 8 is also in a vibrating state during the working process.
[0029] like Figure 2 As shown, a vibrating screed plate 2 is provided in the telescopic extension mechanism, and the vibrating screed plate 2 has a similar structure and function to the main screed plate 7. The vibrating screed plate 2 includes a screed plate 2-1 and a push plate 2-2 integrally and vertically arranged at one end of the screed plate 2-1, and a vibrator is arranged on the screed plate 1-1. The screed plate 2-1 is horizontally arranged to perform vibration slurry leveling on the road surface, realizing the integrated construction of vibration slurry leveling and ensuring the quality of road surface leveling. The push plate 2-2 is vertically arranged to play the role of pushing. The screed plate 2-1 and the push plate 2-2 are an integrated structure, and the vibrator arranged on the screed plate 1-1 can make the screed plate 2-1 and the push plate 2-2 vibrate at the same time.
[0030] The concrete leveler is also provided with a plurality of telescopic support legs 9 at both ends of the main truss 1. Specifically, the telescopic support legs 9 are provided on the lower end surfaces at both ends of the main truss 1. The telescopic support legs 9 are large hydraulic cylinders that can lift the entire machine. After the work is completed, the entire machine can be lifted for easy cleaning.
[0031] The machine is also equipped with an electric control box, a hydraulic pump station, etc. The control system receives control signals from the staff.
[0032] When the concrete screed machine is working, the telescopic assembly drives the lifting assembly and the vibrating screed plate to extend outward to the outermost end of the road surface. Then, the lifting assembly controls the vibrating screed plate to descend to the calibrated height for vibrating screed, and at the same time, the telescopic assembly drives the vibrating screed plate to be recovered. During the recovery process, the push plate 2 faces the concrete screed machine and can scrape and push the excess concrete material. When reaching the edge of the concrete screed machine, the rotating assembly 10 rotates 90°, and the rotating assembly 10 drives the vibrating screed plate to rotate forward, rotating and pushing the excess material. Then, the lifting assembly drives the vibrating screed plate to rise, and the whole machine moves forward at the same time. At this time, the vibrating screed plate of the telescopic part pushes the excess material forward. After moving into place, the telescopic assembly drives the lifting assembly and the vibrating screed plate to extend outward to the outermost end of the road surface. Repeat the above process.
[0033] The present invention provides a telescopic extension mechanism at the end of the main truss, and the telescopic extension mechanism has a telescopic component, a lifting component and a vibrating screed plate; it can be adjusted in real time according to the gradual change in the width of the road surface. By installing telescopic extension mechanisms at both ends of the main truss of the concrete machine, the use range of the concrete screed can be expanded, and it is particularly suitable for construction sites with gradual changes in road width, and can achieve one-time construction and improve work efficiency.
