Description

Technical Field

[0001] This application relates to the field of paver screeds, and more particularly to a folding multi-segment extension adjustment device for paver screeds. Background Technology

[0002] A paver is a construction device mainly used for paving various materials for the base and surface layers of highways. It is primarily used for asphalt concrete paving operations in highways, urban roads, large freight yards, parking lots, docks, and airports. Its core function is to evenly spread the mixed material onto the subbase or base layer of the road surface, and to perform a certain degree of pre-compactment and shaping, thereby ensuring the thickness, width, camber, smoothness, and density of the paved layer. The paver screed is the core component of the paver, mainly responsible for paving and compaction. The road surface material ensures the smoothness and compaction of the road surface. The screed is located at the rear of the paver and directly contacts the road surface for paving and compaction. It is usually made of high-strength steel and has good smoothness and rigidity. When using a conventional paver screed, one end of the connecting frame is installed at one end of the paver. Several electric push rods are installed on the surface of the connecting frame. One end of the electric push rod is equipped with a side frame. The top of the side frame is equipped with a control box. The electric push rods are controlled by the control box to move the side frame, thereby adjusting the length of the screed.

[0003] Regarding the aforementioned technologies, the inventors believe that during the use of conventional pavers, steps that are higher than the road surface are often installed on both sides of the road. This can cause the screed to inevitably collide with the steps when the paver is not operated properly. Repeated collisions can easily cause the screed to deform or even break, thus affecting its use.

[0004] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application, and therefore may include prior art that is not known to those skilled in the art. Utility Model Content

[0005] To address the issue of colliding between the screed of a paver and surrounding steps during use, this application provides a foldable multi-segment extension adjustment device for the screed of a paver.

[0006] The technical solution provided in this application for a folding multi-segment extension adjustment device for a paver screed is as follows:

[0007] A foldable multi-segment extension adjustment device for a paver screed includes a connecting frame and a mounting frame. Electric push rods are fixedly installed at both ends of the connecting frame. One end of each electric push rod is fixedly connected to a side frame. A control box is fixedly installed on the top of the side frame. Several fixed frames are welded to the surface of the mounting frame. A base frame is snapped into the bottom of each fixed frame. A rotating roller is connected to the top of the base frame. One end of the mounting frame is movably installed on the surface of the side frame. The fixed frame has an "L"-shaped cross-section. The top of the rotating roller is rotatably connected to the inner wall of the fixed frame, and the rotating roller is a rubber roller.

[0008] Preferably, the surface of the mounting frame is welded with a plurality of slide rails, and a slider is slidably mounted on the inner wall of the slide rails. One end of the slider is fixedly connected to the surface of the side frame, and the size of the slider surface is adapted to the size of the inner wall of the slide rail.

[0009] Preferably, a pressure detector is fixedly mounted on the surface of the side frame, one end of the pressure detector is movably connected to one side of the mounting frame, and one end of the pressure detector is electrically connected to one end of the control box via a wire.

[0010] Preferably, a plurality of springs are fixedly installed on the surface of the side frame, and the plurality of springs are evenly distributed on one side of the mounting frame, with the center of the springs and the center of the pressure detector on the same straight line.

[0011] Preferably, the bottom end of the rotating roller is rotatably connected to a fixing bolt, the surface of the fixing bolt is engaged with the inner wall of the fixing frame, and the center of the fixing bolt is on the same straight line as the center of the rotating roller.

[0012] Preferably, an auxiliary plate is slidably mounted on one side of the side plate, and a plurality of connecting blocks are fixedly connected to the top of the auxiliary plate. The cross-section of the connecting blocks is T-shaped, and the surface of the connecting blocks is slidably mounted to the inner wall of the slider.

[0013] Preferably, the inner wall of the auxiliary plate is fitted with connecting bolts, and the surface of the connecting bolts is fixedly connected to the inner wall of the side frame.

[0014] In summary, this application includes the following beneficial technical effects:

[0015] 1. By connecting the mounting bracket to one side of the side frame, a fixed frame is welded to the surface of the mounting bracket. A rubber rotating roller is mounted on the bottom of the fixed frame via a base frame. The rotating roller helps to offset the impact force, thereby reducing the damage to the ironing board caused by the collision. A slide rail is welded to the surface of the mounting bracket, and a slider is slidably connected to the inner wall of the slide rail. This helps to prevent the mounting bracket from shifting due to impact. A pressure detector is mounted on the surface of the side frame. One end of the pressure detector is movably connected to the surface of the mounting bracket, so that the pressure detector can detect when the mounting bracket is impacted. Several springs are mounted on one end of the side frame, so that the mounting bracket can automatically rebound after it retracts. Compared with the existing technology, this method effectively improves the protective effect of the ironing board.

[0016] 2. Fixing bolts can also be installed at the bottom of the rotating roller to facilitate removal of the fixing bolts from the inner wall of the fixing frame, thereby facilitating the replacement of the rotating roller. An auxiliary plate is installed at one end of the side plate. The auxiliary plate is slidably connected to the inner wall of the slider by means of a connecting block, so as to avoid the situation where asphalt concrete gets on the fixing bolts and makes them difficult to remove. Connecting bolts are snapped into the inner wall of the auxiliary plate, so as to facilitate the removal of the auxiliary plate after the connecting bolts are removed, and to avoid the auxiliary plate obstructing the removal of the fixing bolts; thus effectively improving the use effect of the device.
