Description

Technical Field

[0001] This utility model relates to an adjustable hydraulic rigid pipe fixing mechanism, belonging to the field of aerial work platforms. Background Technology

[0002] On aerial work platforms, some hoses inside the boom may stretch after being filled with pressurized hydraulic oil, which could interfere with certain moving parts and cause damage and oil leakage. Therefore, these hoses need to be pre-stretched before connecting both ends to the fixing mechanism. The pre-stretched hoses exert tension on the fixing mechanisms on both sides, and if not properly fixed, they will loosen.

[0003] Some hoses inside the boom cannot be tightened by passing through the hoses inside the cable chain. Due to manufacturing errors, the length of these hoses may vary. Therefore, the fixing mechanism connected to these hoses needs to be adjustable.

[0004] In some vehicle models, the fixing mechanism has a pre-stretched hose on one side and a loose hose that needs to be adjusted on the other. If not properly fixed, the entire mechanism may move toward the pre-stretched hose side. Therefore, an adjustable mechanism is needed that can be effectively fixed after adjustment. Utility Model Content

[0005] The purpose of this utility model is to overcome the above-mentioned shortcomings in the existing technology and to provide an adjustable hydraulic hard pipe fixing mechanism with a reasonable structural design.

[0006] The technical solution adopted by this utility model to solve the above problems is as follows: the adjustable hydraulic rigid pipe fixing mechanism includes a pre-stretched hose, a rigid pipe, a hose, and a support plate. The two ends of the rigid pipe are respectively connected to the pre-stretched hose and the hose. Its structural features are: it also includes a locking nut, a welding joint, an adjusting bolt, and a pressure plate assembly. The rigid pipe passes through the pressure plate assembly, the pressure plate assembly is welded to the support plate, the welding joint is welded to the rigid pipe, the adjusting bolt passes through the welding joint and abuts against the pressure plate assembly, and the locking nut is installed on the adjusting bolt and abuts against the welding joint.

[0007] Furthermore, the pressure plate assembly includes fixing bolts, an upper pressure plate, and a lower pressure plate. The lower pressure plate is welded to the support plate, and the upper pressure plate is fixed to the lower pressure plate by fixing bolts. The rigid tube is located between the upper pressure plate and the lower pressure plate.

[0008] Furthermore, the upper pressure plate is provided with a countersunk hole, and the lower pressure plate is provided with a threaded hole, and the fixing bolt passes through the countersunk hole and connects with the threaded hole.

[0009] Furthermore, the welding joint is provided with a light hole, and the adjusting bolt passes through the light hole.

[0010] Compared with the prior art, the present invention has the following advantages: the adjustable hydraulic rigid pipe fixing mechanism fixes the rigid pipe in the radial direction through the upper and lower pressure plates, and fixes the rigid pipe in the axial direction through the locking nut, welding bracket and adjusting bolt. This achieves double fixation of the rigid pipe and prevents the rigid pipe from moving when the upper and lower pressure plates are loose. Attached Figure Description

[0018] Example

[0019] See Figures 1 to 5As shown in the accompanying drawings, the structures, proportions, sizes, etc., depicted in this specification are merely for illustrative purposes to aid those skilled in the art and to provide a clear understanding. They are not intended to limit the scope of this invention and therefore have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, provided they do not affect the effectiveness or purpose of this invention, should still fall within the scope of the technical content disclosed in this invention. Furthermore, the use of terms such as "upper," "lower," "left," "right," "middle," and "one" in this specification is solely for clarity and not intended to limit the scope of this invention. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of this invention.

[0020] The adjustable hydraulic rigid pipe fixing mechanism in this embodiment includes a pre-stretched hose 1, a rigid pipe 2, a locking nut 3, a welding bracket 4, an adjusting bolt 5, a hose 6, a bracket plate 12, and a pressure plate assembly. There are two sets of pressure plate assemblies, which are arranged along the length of the rigid pipe 2.

[0021] In this embodiment, the two ends of the rigid tube 2 are connected to the pre-stretched flexible tube 1 and the flexible tube 6 respectively. The rigid tube 2 passes through the pressure plate assembly, which is welded to the support plate 12. The welding joint 4 is welded to the rigid tube 2. The welding joint 4 is provided with a light hole 13. The adjusting bolt 5 passes through the light hole 13 and abuts against the pressure plate assembly. The locking nut 3 is installed on the adjusting bolt 5 and abuts against the welding joint 4.

[0022] The pressure plate assembly in this embodiment includes a fixing bolt 7, an upper pressure plate 8, and a lower pressure plate 9. The lower pressure plate 9 is welded to the support plate 12. The upper pressure plate 8 is fixed to the lower pressure plate 9 by the fixing bolt 7. The rigid tube 2 is located between the upper pressure plate 8 and the lower pressure plate 9. The upper pressure plate 8 is provided with a countersunk hole 10, and the lower pressure plate 9 is provided with a threaded hole 11. The fixing bolt 7 passes through the countersunk hole 10 and connects with the threaded hole 11.

[0023] Specifically, the rigid tube 2 is placed between the upper pressure plate 8 and the lower pressure plate 9. The lower pressure plate 9 is welded and fixed to the support plate 12. The upper pressure plate 8 has a countersunk hole 10, and the lower pressure plate 9 has a threaded hole 11. The fixing bolt 7 passes through the countersunk hole 10 and the threaded hole 11 to connect and clamp the rigid tube 2 between the upper pressure plate 8 and the lower pressure plate 9.

[0024] The pre-stretched hose 1 and hose 6 are connected to both ends of the rigid pipe 2 respectively. After the pre-stretched hose 1 is connected to the rigid pipe 2, there is a leftward pulling force. After the hose 6 is connected to the rigid pipe 2, there is no pulling force. The welding joint 4 has a light hole 13. The welding joint 4 is welded to the rigid pipe 2. The adjusting bolt 5 passes through the light hole 13 and contacts the surface of the upper pressure plate 8. One of the locking nuts 3 contacts the welding joint 4, and the other locking nut 3 contacts the other locking nut 3 and is tightened. The position of the rigid pipe 2 can be adjusted left and right.

[0025] During installation, the adjustable hydraulic rigid pipe fixing mechanism is first loosened to allow the rigid pipe 2 to move along its length. After adjusting the position of the rigid pipe 2, the adjusting bolt 5 is pressed against the upper pressure plate 8. The locking nut 3 is then tightened to fix the position of the adjusting bolt 5. Finally, the fixing bolt 7 is tightened to clamp the rigid pipe 2 between the upper pressure plate 8 and the lower pressure plate 9.
