A telescopic screed adjustment system for a paving machine

Abstract

This invention relates to an adjustment system for a telescopic guide plate for a paver, belonging to the field of pavers. The technical solution includes a main frame section with a telescopic section on one side. The telescopic section includes a first sliding post and a side baffle. The other end of the first sliding post is fixed to the side baffle, which is connected to a guide plate. A connector is located on the side of the guide plate near the side baffle. The connector has a first through groove in its center, and the connecting plate is positioned within this groove. The width and length of the first through groove are both greater than the width and length of the connecting plate. By using the connector on the guide plate and the connecting plate on the side baffle, adjustments to the height difference and elevation angle of the telescopic section can be made during paver operation without disassembling the bolts between the side baffle and the guide plate. Adjustments are made concurrently with construction to meet normal construction requirements.

Description

Technical Field

[0001] This invention relates to the field of paver technology, and more specifically to a telescopic guide plate adjustment system for pavers. Background Technology

[0002] Currently, the screed of pavers is telescopic. The screed includes a main screed, a telescopic screed, and a splicing screed. The main screed and the telescopic screed are slidably connected. When it is necessary to widen the screed, a splicing screed is installed on the telescopic screed. When the splicing screed is installed, a guide plate is also required on the telescopic screed to ensure that the paving material can be continuously and evenly conveyed to both sides.

[0003] The guide plates used in the screed section of the paver include fixed guide plates and telescopic guide plates. Fixed guide plates are bolted to the base frame. This bolted installation prolongs preparation time, increases labor intensity, and shortens the telescopic range, significantly reducing the screed's flexibility. Therefore, telescopic guide plates were designed to extend and retract synchronously with the screed, eliminating the need for disassembly and reassembly for each construction operation.

[0004] However, the telescopic guide plate is fixed to the movable part (side baffle) by bolts. Due to changes in road conditions during construction, it is usually necessary to adjust the height difference and elevation angle between the guide plate and the telescopic section to adapt to the changes in road conditions. When adjusting the height difference and elevation angle of the telescopic section, the fixing bolts of the guide plate need to be removed to make corresponding adjustments according to the changes in the height difference and elevation angle of the telescopic section. Pre-adjustment before construction often cannot meet the requirements of normal construction. However, stopping the machine for adjustment during construction is time-consuming and laborious, reducing construction efficiency. Summary of the Invention

[0005] This invention addresses the problem of low construction efficiency caused by the need to disassemble bolts on telescopic guide plates in existing technologies to adjust them according to changes in the height difference and elevation angle of the telescopic section. It provides a self-adjusting telescopic guide plate adjustment system for pavers.

[0006] The technical solution adopted in this invention is as follows:

[0007] A telescopic guide plate adjustment system for a paver includes a main frame and a telescopic section on one side of the main frame. The telescopic section includes a first sliding column and a side baffle. One end of the first sliding column is telescopically mounted inside the main frame, and the other end of the first sliding column is fixedly connected to the side baffle. A guide plate is connected to the side baffle, and the upper end of the guide plate is hinged to the main frame. A connector is provided on the side of the guide plate near the side baffle. The connector has a first through groove in its middle. A connecting plate is provided on the side baffle. The lower end of the connecting plate is fixedly mounted on the side baffle. A second through groove is opened at the lower end of the connecting plate. The upper end of the connecting plate passes through the first through groove, and the lower end of the connector passes through the second through groove. The lower end of the connector can move within the second through groove.

[0008] Preferably, the connector includes a first clamping plate and a second clamping plate. The first clamping plate is fixed to the guide plate, and the second clamping plate is bolted to the first clamping plate. Two spacers are provided between the first and second clamping plates. The upper end of the connecting plate is located between the two spacers, and the upper end of the connecting plate is located between the first and second clamping plates. The first and second clamping plates and the spacers in between ensure a more stable connection between the connector and the connecting plate. This prevents the connector from separating from the connecting plate while allowing the middle part of the connecting plate to move within the connector, thus ensuring the stability of the equipment operation during construction.

[0009] Preferably, the connecting plate is further provided with a first limiting mechanism, which is located on one side of the second clamping plate and can abut against the second clamping plate. Through the provided first limiting mechanism, a large displacement can be achieved between the guide plate and the side baffle during equipment operation.

[0010] Preferably, the first limiting mechanism includes a first limiting plate with a receiving groove. A top ball is disposed within the receiving groove and can roll within the groove. The side of the top ball closest to the second clamping plate can abut against the second clamping plate. Through the top ball, it can roll freely between the first limiting plate and the second clamping plate with spherical contact, thereby enabling free adjustment of height difference and elevation angle.

[0011] Preferably, the first limiting plate is arc-shaped. This arc-shaped first limiting plate ensures that the ball always contacts the second clamping plate at different angles, preventing it from losing its limiting function after detachment.

[0012] Preferably, it also includes a mounting base, on which a second mounting plate is provided, and on the main frame a first mounting plate is also provided. The first mounting plate and the second mounting plate are connected by bolts. A second sliding column is connected to the mounting base. One end of the second sliding column is located inside the mounting base. The second sliding column can extend and retract along the axial direction in the mounting base. The other end of the second sliding column is fixedly connected to the guide plate.

[0013] Preferably, the mounting base is provided with two support rings, both of which are sleeved on the second sliding column. These support rings enable the mounting base to provide good guidance and support for the second sliding column.

[0014] Preferably, the adjustment system further includes a second limiting mechanism, which comprises a second limiting plate and a wear-resistant plate. The second limiting plate is disposed on the guide plate, and the wear-resistant plate is disposed on the main section frame. The second limiting plate and the wear-resistant plate can abut against each other. This ensures that the second limiting plate and the wear-resistant plate can abut against each other when the paving material pushes the guide plate, preventing the guide plate from rotating too much.

[0015] As can be seen from the above technical solutions, the advantages of this invention are as follows: By using the connecting piece on the guide plate and the connecting plate on the side baffle, during paver operation, when adjusting the height difference and elevation angle of the telescopic section, it is not necessary to disassemble the bolts between the side baffle and the guide plate to adjust accordingly to changes in the height difference and elevation angle. Adjustments can be made simultaneously with construction to meet normal construction requirements. The first clamping plate, the second clamping plate, and the spacer between them ensure a more stable connection between the connecting piece and the connecting plate. This prevents separation of the connecting piece and the connecting plate while ensuring the middle part of the connecting plate can move within the connecting piece, thus guaranteeing the stability of the equipment during construction. The first limiting mechanism allows for significant displacement between the guide plate and the side baffle during equipment operation. The top ball allows free rolling between the first limiting plate and the second clamping plate with spherical contact, enabling free adjustment of the height difference and elevation angle. The arc-shaped first limiting plate ensures that the top ball always abuts against the second clamping plate at different angles, preventing loss of its limiting function after separation. The first and second mounting plates securely install the mounting base onto the main frame, improving the axial parallelism of the first and second sliding columns and enhancing the smoothness of the telescopic section during expansion and contraction, reducing jamming. The support ring ensures the mounting base provides good guidance and support for the second sliding column. The second limiting plate and wear-resistant plate abut against each other when the paving material pushes the guide plate, preventing excessive rotation of the guide plate.

Obviously, the embodiments described below are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0025] Example:

[0026] like Figures 1-5As shown, a telescopic guide plate adjustment system for a paver includes a main frame 1. A telescopic section 2 is provided on one side of the main frame 1. The telescopic section 2 includes a first sliding column 21 and a side baffle 22. One end of the first sliding column 21 is located inside the main frame 1 and can extend and retract along the axial direction of the main frame 1. The other end of the first sliding column 21 is fixedly connected to the side baffle 22. The side baffle 22 is connected to a guide plate 3. A connector 31 is provided on the side of the guide plate 3 near the side baffle 22. A first through groove 314 is provided in the middle of the connector 31. A connecting plate 221 is provided on the side baffle 22. The lower end of the connecting plate 221 is fixedly located on the side baffle 22. A second through groove 224 is opened at the lower end of the connecting plate 221. The upper end of the connecting plate 221 passes through the first through groove 224. A through groove 314 is provided, and the lower end of the connector 31 passes through the second through groove 224. The lower end of the connector 31 can move within the second through groove 224. A first mounting plate 11 is also provided on the main frame 1. The adjustment system also includes a mounting base 4, on which a second mounting plate 41 is provided. The first mounting plate 11 and the second mounting plate 41 are connected by bolts. A second sliding column 23 is connected to the mounting base 4. One end of the second sliding column 23 is located inside the mounting base 4 and can extend and retract along the axial direction of the mounting base 4. The other end of the second sliding column 23 is fixedly connected to the guide plate 3. A connector 31 is provided on the side of the guide plate 3 near the side baffle 22. A first through groove 314 is provided in the middle of the connector 31. A connecting plate 221 is provided on the side baffle 22. Both ends of the connecting plate 221 are fixedly mounted on the side baffle 22. The middle part of the connecting plate 221 is located in the first through groove 314. The width and length of the first through groove 314 are both greater than the width and length of the middle part of the connecting plate 221. In this embodiment, the connecting member 31 includes a first clamping plate 311 and a second clamping plate 312. The first clamping plate 311 is fixedly mounted on the guide plate 3. The second clamping plate 312 is connected to the first clamping plate 311 by bolts. Two pads 313 are provided between the first clamping plate 311 and the second clamping plate 312. The upper end of the connecting plate 221 is located between the two pads 313 and between the first clamping plate 311 and the second clamping plate 312. With this configuration, the connecting member 31 on the guide plate 3 and the side baffle 22 are connected. The connecting plate 221 installed on plate 22 allows for adjustments to the height difference and elevation angle of the telescopic section 2 during paver operation without disassembling the bolts between the side baffle 22 and the guide plate 3. Adjustments are made concurrently with construction to meet normal operation requirements. The first mounting plate 11 and the second mounting plate 41 securely install the mounting base 4 onto the main frame 1, improving the axial parallelism of the first sliding column 21 and the second sliding column 23, thus enhancing the smoothness of the telescopic section 2 during expansion and contraction and reducing jamming. The first clamping plate 311, the second clamping plate 312, and the spacer 313 further stabilize the connection between the connecting piece 31 and the connecting plate 221.While ensuring that the middle part of the connecting plate 221 can move within the connecting member 31, the connecting member 31 and the connecting plate 221 are kept from separating, thus ensuring the stability of the equipment operation during construction.

[0027] In this embodiment, a first limiting mechanism is also provided on the connecting plate 221. The first limiting mechanism is located on one side of the second clamping plate 312 and can abut against the second clamping plate 312. In this embodiment, the first limiting mechanism includes a first limiting plate 222, which is arc-shaped. A receiving groove is provided on the first limiting plate 222, and a top ball 223 is provided in the receiving groove. The top ball 223 can roll in the receiving groove, and the side of the top ball 223 near the second clamping plate 312 can abut against the second clamping plate 312. With this design, the first limiting mechanism allows for significant displacement between the guide plate 3 and the side baffle 22 during equipment operation. The top ball 223 can roll freely between the first limiting plate 222 and the second clamping plate 312 with spherical contact, thus enabling free adjustment of height difference and elevation angle. The arc-shaped first limiting plate 222 ensures that the top ball 223 can always abut against the second clamping plate 312 at different angles, preventing it from losing its limiting function after separation.

[0028] In this embodiment, a support ring 42 is provided inside the mounting base 4. There are two support rings 42, and both support rings 42 are sleeved on the second sliding column 23. In this way, the mounting base 4 can play a good guiding and supporting role for the second sliding column 23 through the support rings 42.

[0029] In this embodiment, the adjustment system also includes a second limiting mechanism, which includes a second limiting plate 51 and a wear-resistant plate 52. The second limiting plate 51 is disposed on the guide plate 3, and the wear-resistant plate 52 is disposed on the main frame 1. The second limiting plate 51 and the wear-resistant plate 52 can abut against each other. This arrangement allows the second limiting plate 51 and the wear-resistant plate 52 to abut against each other when the paving material pushes the guide plate 3, thus avoiding excessive rotation angle of the guide plate and reducing the construction effect.
