Description

Technical Field

[0001] The utility model relates to the technical field of asphalt leveling, in particular to an asphalt leveling device for municipal road construction. Background Art

[0002] Municipal engineering refers to municipal infrastructure construction projects. Asphalt pavement refers to various types of pavement paved with road asphalt materials mixed into mineral materials. Asphalt binder improves the ability of paving aggregate to resist damage to the road surface caused by driving and natural factors, making the road surface smooth, dust-free, impermeable and durable. Therefore, asphalt pavement is the most widely used high-grade pavement in road construction, so asphalt leveling equipment is needed for municipal road construction.

[0003] For example, the Chinese patent CN218322225U discloses an asphalt leveling device. By setting a driving component, it is convenient to push the device automatically. People only need to control the direction. The leveling of asphalt is more convenient and quick. The operation is automated, and the leveling saves time and effort. People do not need to push. By setting the leveling component, it is convenient to adjust the leveling of asphalt of different thicknesses. The adjustment is automated and the use is more flexible.

[0004] However, there are certain defects in this patent. The device drives the screw to rotate through the forward and reverse motors, and adjusts the position of the leveling wheel through the screw. Since the leveling wheel has a large gravity itself and is located on one side of the screw, the leveling wheel will always squeeze the side wall of the screw. In the natural state, the screw is always subjected to the squeezing force of the support plate. When the position of the leveling wheel is adjusted, it will cause certain damage to the side wall of the screw, thereby reducing the service life of the device. Utility Model Content

[0007] A pulley fixedly mounted on the bottom of the fixed plate;

[0008] and a processing assembly disposed at a side wall of the fixing plate;

[0009] The processing assembly includes an adjustment mechanism installed at a side wall position of the fixed plate, and the adjustment mechanism is located at a top position of the fixed plate;

[0011] Preferably, there are four pulleys, which are of equal shape and size, and are respectively fixedly mounted at the four corners of the bottom of the fixed plate, so that the operator can move the position of the entire device through the pulleys.

[0012] Preferably, a counterweight block is fixedly installed on the top of the fixed plate, a pushing handle is fixedly installed on the left side of the top of the fixed plate, and a reinforcing rod is fixedly installed on the inner wall of the pushing handle.

[0013] Preferably, the adjustment mechanism includes a driving motor, which is fixedly mounted on the top of the fixed plate, and the output end of the driving motor is transmission-mounted with a rotating wheel, and the side wall of the rotating wheel is transmission-mounted with a belt, and the other end of the belt is transmission-mounted with a bidirectional threaded rod, and the side wall of the bidirectional threaded rod is installed with an adjustment plate, and both ends of the bidirectional threaded rod are rotatably mounted with L-shaped plates through bearings, and the other end of the L-shaped plate is fixedly connected to the side wall of the fixed plate.

[0014] Preferably, the side wall of the bidirectional threaded rod is threadedly connected to the inner wall of the adjustment plate, the bottom of the adjustment plate is slidably connected to the top of the fixed plate, there are two adjustment plates, and the two adjustment plates are symmetrically arranged relative to the middle surface of the fixed plate in the front-to-back direction. When the double-threaded rod rotates, the position of the adjustment plate can be driven to move.

[0015] Preferably, the stabilizing mechanism includes a limit plate, which is fixedly mounted on the top of the fixed plate, and a rectangular block is slidably mounted on the side wall of the limit plate, a sliding rod is fixedly mounted on one end of the rectangular block, and the side wall of the sliding rod is slidably connected to the inner wall of the adjusting plate with an arc groove provided on the inner wall, and a limit block is fixedly mounted on the other end of the sliding rod, and the side wall of the limit block is slidably connected to the side wall of the adjusting plate, and a support rod is fixedly mounted on the other end of the rectangular block, and a connecting block is fixedly mounted on the side wall of the connecting block, and a leveling wheel is rotatably mounted on the inner wall of the installing block.

[0016] Preferably, an arc tube is fixedly installed on the side wall of the rectangular block, there are two arc tubes, the shapes and sizes of the two arc tubes are equal, the other ends of the two arc tubes are fixedly connected to the side wall of the support rod, and the two arc tubes are symmetrically arranged with respect to the middle surface in the front-to-back direction of the rectangular block, and the stability of the leveling wheel is improved by setting up the arc tube.

[0017] The utility model provides an asphalt leveling device for municipal road construction, which has the following beneficial effects:

[0018] (1) When the operator uses the device of the utility model, when the operator needs to adjust the height of the leveling wheel, the driving motor can be directly turned on. Under the joint action of the rotating wheel, the belt, the bidirectional threaded rod and the adjusting plate, the driving motor will squeeze the side wall of the slide rod when the adjusting plate slides, causing the slide rod to slide inside the arc groove of the inner wall of the adjusting plate. When the slide rod slides, it can drive the position of the rectangular block, the support rod and the leveling wheel to move, so as to adjust the height of the leveling wheel, thereby solving the problem that the device drives the screw rod to rotate through the forward and reverse motors and adjusts the position of the leveling wheel through the screw rod. Since the leveling wheel has a large weight and is located on one side of the screw rod, the leveling wheel will always squeeze the side wall of the screw rod. In the natural state, the screw rod is always subjected to the squeezing force of the support plate. When the position of the leveling wheel is adjusted, it will cause certain damage to the side wall of the screw rod, thereby reducing the service life of the device.

[0019] (2) When the utility model is lifted by the position of the slide rod, it will drive the rectangular block to slide on the side wall of the limit plate, making the leveling wheel height more stable when being adjusted. The limiting block can limit one end of the slide rod to prevent one end of the slide rod from detaching from the inner wall of the arc groove, thereby improving the stability of the device during operation and facilitating the operator to better use the device.

[0035] Example 2

[0036] On the basis of Example 1, a preferred embodiment of the asphalt leveling device for municipal road construction provided by the utility model is as follows: Figures 1 to 5 As shown: the stabilizing mechanism 42 includes a limit plate 421, which is fixedly installed on the top of the fixed plate 1, and a rectangular block 427 is slidably installed on the side wall of the limit plate 421, and a sliding rod 428 is fixedly installed on one end of the rectangular block 427, and the side wall of the sliding rod 428 is slidably connected to the inner wall of the adjusting plate 416 with an arc groove provided on the inner wall, and a limiting block 429 is fixedly installed on the other end of the sliding rod 428, and the side wall of the limiting block 429 is slidably connected to the side wall of the adjusting plate 416, and a support rod 426 is fixedly installed on the other end of the rectangular block 427, and a connecting block 424 is fixedly installed on the other end of the support rod 426, and a mounting block 423 is fixedly installed on the side wall of the connecting block 424, and a leveling wheel 422 is rotatably installed on the inner wall of the mounting block 423.
