Description

Technical Field

[0001] This utility model relates to the field of hydraulic pipeline technology for cleaning machines, and in particular to a limit protection device for hydraulic pipelines of cleaning machines. Background Technology

[0002] Hydraulic lines in screen cleaning machines are typically connected using flexible hoses. To further improve connection stability, flanges are installed at both ends of the hoses to reduce oil leakage at the joints, thus ensuring safe operation of the equipment. However, in actual use, the hoses are frequently squeezed, and deformed hoses lead to reduced oil output, severely affecting the normal operation of the screen cleaning machine. Furthermore, due to the high-frequency vibrations generated during operation, the hoses are prone to swaying under resonance, affecting connection stability and potentially damaging other components. Clearly, current screen cleaning machines lack effective measures for securing and protecting the hoses. Utility Model Content

It has a reasonable structural design, is easy to install and remove, and can be matched according to the position of the flanges at both ends of the hose, without being limited by the installation position. It not only effectively protects the hose and prevents it from being squeezed, but also limits the position of the hose, improves the connection stability and prevents damage to other components, thus solving the problems existing in the prior art.

[0004] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows:

[0005] A limiting protection device for hydraulic pipelines of a cleaning machine includes end fixing components connected to flanges at both ends of a connector. The two end fixing components are connected by a connector. Each end fixing component includes a fixed sleeve fitted onto a flexible hose.

[0023] like Figure 1-6 As shown in this embodiment, a limiting protection device for hydraulic pipeline of a cleaning machine includes end fixing members connected to flanges at both ends of the connector. The two end fixing members are connected by a connector. The end fixing member includes a fixed sleeve 1 sleeved on the hose. The outer end of the fixed sleeve 1 is connected to the flange on the corresponding side through a fixed plate 2. An annular groove 3 is provided on the outer wall of the fixed sleeve 1 on the inner side along its circumferential direction. The outer end of an adjusting sleeve 4 is movably abutted against the inner end of the fixed sleeve 1. An extension sleeve 5 is provided on the adjusting sleeve 4 on the outer side, which is movably sleeved on the fixed sleeve 1. An annular flange 6 that cooperates with the annular groove 3 is provided on the inner wall of the extension sleeve 5 at the position corresponding to the annular groove 3. A support plate 7 is provided on the outer wall of the adjusting sleeve 4 at the middle position. The adjusting sleeve 4 is bent from the position of the support plate 7 to the inner end position of the adjusting sleeve 4. A limiting member that cooperates with the adjusting sleeve 4 is provided on the fixed sleeve 1.

[0024] Optionally, the limiting member includes a limiting sleeve 8 movably sleeved on the adjusting sleeve 4. The inner end of the limiting sleeve 8 abuts against the support plate 7, and the inner wall of one side of its outer end movably abuts against the outer wall of the fixed sleeve 8. A spring groove 9 is provided along the circumferential direction on the outer wall of the adjusting sleeve 4 from the position of the support plate 7 to the position of the outer end of the adjusting sleeve 4. A spring clip 10 is provided along the circumferential direction on the inner wall of the limiting sleeve 8, which is engaged in the spring groove 9. The plate 10 abuts against the inner end side wall of the spring slot 9. A return spring 11 is provided in the spring slot 9 and sleeved on the adjusting sleeve 4. The inner end of the return spring 11 abuts against the spring card 10. Several toothed grooves 12 are provided along the circumferential direction on the inner wall of the limiting sleeve 8 on one side of the inner end. Each toothed groove 12 extends to the spring card 10. Several racks 13 that mesh with each toothed groove 12 are provided on the outer wall of the adjusting sleeve 4 corresponding to the position of each toothed groove 12.

[0025] Optionally, a plurality of horizontally arranged guide strips 14 are provided at intervals along the circumference of the outer wall of the fixed sleeve 1, and a guide groove 15 that cooperates with each guide strip 14 is provided on the inner wall of the limiting sleeve 8 on one side of the outer end. The limiting sleeve 8 can move horizontally along the direction of the guide strips 14 through each guide groove 15, effectively preventing the limiting sleeve 8 from rotating radially and facilitating the operation of the operator.

[0026] Optionally, a plurality of grooves 16 are provided at intervals along the length of the outer wall of the limiting sleeve 8. The grooves 16 can increase the friction between the hand and the limiting sleeve 8, making it easier for the operator to operate.

[0027] Optionally, the angle formed by the centerline of the bent section of the adjusting sleeve 4 and the centerline of its horizontal section is 120 degrees.

[0028] Optionally, the support plate 7 is hexagonal prism in shape. This facilitates the operator's grip and allows them to apply force to the adjusting sleeve 4 to adjust its rotation.

[0029] Optionally, the connector includes two arc-shaped clamping plates 17, with connecting plates 18 on the front and rear sides of the arc-shaped clamping plates 17 respectively. The two arc-shaped clamping plates 17 are closed into a cylindrical shape and are sleeved on the adjusting sleeve 4 on one side of the inner end. The two arc-shaped clamping plates 17 are connected by several fixing bolts 19 passing through the connecting plates 18 on the same side.

[0030] When installing the connector, first attach one end fixing piece to the hose and abut the fixing plate 2 against the flange on that side. Tighten the nuts and bolts on the original flange to fix the position of the fixing sleeve 1. Then, attach the other end fixing piece to the hose and install the flange on the other side. Tighten the nuts and bolts on the flange on that side to fix the position of the fixing sleeve 1. Next, straighten the adjusting sleeves 4 of the two end fixing pieces with the hose and pull out the limiting sleeve 8. The limiting sleeve 8 moves outward along the guide strip 14 on the fixing sleeve 1 through the guide groove 15, thereby separating the toothed grooves 12 of the limiting sleeve 8 from the toothed racks 13 on the adjusting sleeve 4. At this time, the return spring 11 is in a compressed state. Then, turn the adjusting sleeve 4. The adjusting sleeve 4 rotates radially along the annular groove 3 of the fixing sleeve 1 through the annular flange 6 of the extending sleeve 5 until the bent part of the adjusting sleeve 4 is flush with the hose. Then, loosen the limiting sleeve 8. Under the deformation restoring force of the return spring 11, push the limiting sleeve 8 back to its original position, causing the toothed groove 12 to re-engage with the rack 13, thereby limiting the position of the adjusting sleeve 4. Adjust the end fixing piece on the other side in the same way. Finally, use the connector to fix it, so that the arc-shaped clamping plates 17 on both sides are closed on the hose. Its structure is reasonably designed and easy to install and remove. It can be matched according to the position of the flanges at both ends of the hose, and is not limited by the installation position. It not only effectively protects the hose and avoids the hose being squeezed, but also limits the position of the hose, improves the connection stability and prevents damage to other components, solving the problems existing in the prior art.
