Description

Technical Field

[0001] The utility model relates to the technical field of controllable pitch propeller assembly, in particular to an assembly tool for a hydraulic distributor of a controllable pitch propeller. Background Art

[0002] The hydraulic distributor is an important component of the adjustable pitch propeller propulsion device. It is responsible for distributing the hydraulic oil of the hydraulic system to the rotating adjustable pitch propeller pitch cylinder, that is, the oil distribution function; the rotating mandrel of the hydraulic distributor is connected to the propeller shaft through a coupling. This connection method requires adjusting the concentricity of the propeller shaft and the mandrel. At present, due to the structural limitations of the hydraulic distributor, the use of conventional roller rigid support will interfere with other parts, so it cannot be used normally. The mandrel can only be lifted with a sling. The mandrel is in a floating state during the assembly process, which makes it difficult to adjust the concentricity of the mandrel and the propeller shaft, making assembly difficult. Summary of the invention

[0003] The purpose of the utility model is to overcome the above-mentioned shortcomings and provide an assembly tool for a hydraulic distributor of a controllable pitch propeller, so as to realize the adjustment and fixation of the core shaft of the hydraulic distributor. The diameter of the core shaft is increased in disguise by arranging two Haversian plate jackets on the core shaft to avoid the interference between other parts on the core shaft and the roller bracket. The roller bracket is adjustable left and right, front and back, so as to facilitate the alignment of the core shaft of the hydraulic distributor with the propeller shaft.

[0004] The purpose of the utility model is achieved in this way:

[0005] A hydraulic distributor assembly tool for a pitch controllable propeller comprises a jacket and an adjustable roller bracket, wherein the jacket is composed of two upper and lower Harvard-type semi-jackets, and the adjustable roller bracket comprises a supporting roller, a support, an adjustment plate and a base, wherein the Harvard-type semi-jacket located at the bottom is symmetrically provided with supporting rollers on the left and right sides, the supporting rollers are movably arranged on the support, the support is fixed on the adjustment plate, and the adjustment plate which can be adjusted up, down, left and right is arranged in the base.

[0006] Preferably, left and right adjustment bolts are provided on the left and right side plates of the base, and the left and right adjustment bolts pass through the side plates of the base and abut against the sides of the adjustment plate. A height adjustment bolt is provided on the adjustment plate, and the height adjustment bolt passes through the adjustment plate and abuts against the base.

[0007] Preferably, a guard ring is further provided on the outer side of the lower Harvard half jacket, and the guard ring is welded to the lower Harvard half jacket.

[0008] Preferably, the side plates of the base are provided with threaded holes corresponding to the left and right adjustment bolts, and the adjustment plate is also provided with threaded holes corresponding to the height adjustment bolts.

[0009] Preferably, the Harvard faces of the two Harvard half jackets are fixed by bolts.

[0010] Preferably, the jacket is mounted on the mandrel of the hydraulic distributor to form two rigid supports, one at the root of the shaft extension of the mandrel and the other at the inner recess of the tail of the mandrel, wherein the portion extending into the coupling is the shaft extension of the mandrel.

[0011] The beneficial effects of the utility model are:

[0012] The diameter of the mandrel is increased in disguise by setting two Haversian plate jackets on the mandrel to avoid interference between other parts on the mandrel and the roller bracket. The roller bracket is adjustable left and right, front and back, to facilitate alignment of the mandrel of the hydraulic distributor and the propeller shaft.

[0013] The hydraulic distributor mandrel can be adjusted and fixed to meet the equipment installation requirements while reducing the risks during installation and improving the work efficiency of the shipyard. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] See also Figure 1 and Figure 2 The utility model relates to an assembly tool for a hydraulic distributor of a pitch controllable propeller, comprising a jacket 1 and an adjustable roller bracket 2. The jacket 1 is composed of two upper and lower Harvard-type semi-jackets 1.1. The Harvard surfaces of the two Harvard-type semi-jackets 1.1 are fixed by bolts. The adjustable roller bracket 2 comprises a supporting roller 2.1, a support 2.2, an adjusting plate 2.3, a base 2.4, a height adjustment bolt 2.5 and left and right adjustment bolts 2.6. The Harvard-type semi-jacket 1.1 located at the bottom is symmetrically provided with support rollers 2.1, 2.2, 2.3, 2.4, 2.5, 2.6, 2.6, 2.7, 2.8, 2.9, 3.0, 3.10, 3.2, 3.3, 3.4, 3.5, 3.6, 3.7, 3.8, 3.9, 4. Roller 2.1, the supporting roller 2.1 is movably arranged on a support 2.2, the support 2.2 is fixed on an adjusting plate 2.3, the adjusting plate 2.3 is arranged in a base 2.4, left and right adjusting bolts 2.6 are arranged on left and right side plates of the base 2.4, the left and right adjusting bolts 2.6 pass through the side plates of the base 2.4 and abut against the side of the adjusting plate 2.3, and a height adjusting bolt 2.5 is arranged on the adjusting plate 2.3, and the height adjusting bolt 2.5 passes through the adjusting plate 2.3 and abuts against the base 2.4.

[0018] The side plates of the base 2.4 are provided with threaded holes corresponding to the left and right adjusting bolts 2.6, and the adjusting plate 2.3 is also provided with threaded holes corresponding to the height adjusting bolts 2.5.

[0019] A guard ring 1.1.1 is also provided outside the lower Harvard half jacket 1.1. The guard ring 1.1.1 is welded to the lower Harvard half jacket 1.1 to increase the contact area between the support roller and the jacket, increase the axial area, and provide a rigid and stable support for better adjustment.

[0020] Working principle:

[0021] The coupling 3 is sleeved on the propeller shaft 4, and the tooling is arranged at the root of the shaft extension of the mandrel 5 of the hydraulic distributor (the part extending into the coupling is the shaft extension of the mandrel 5) and the inner concave part. The two Harvard-type semi-jackets 1 clamp the mandrel 5 by bolts, and the two supporting rollers 2.1 support the jacket 1 on the left and right. The jacket 1 and the mandrel 3 inside are adjusted up, down, left and right by adjusting the height bolts 2.5 and the left and right adjusting bolts 2.6 to achieve the centering of the propeller shaft and the mandrel.

[0022] Since the tooling is arranged at the recessed part of the root of the extension of the core shaft 5 and the tail of the core shaft, during the assembly process of the core shaft, the propeller shaft and the coupling, the tooling avoids contact with the coupling, thereby ensuring the smooth press-fitting of the coupling. After the installation of the coupling is completed, the tooling can be removed by disassembling the bolts of the two Haversian half sets, which is convenient and flexible.

[0023] In addition to the above embodiments, the present invention also includes other implementation modes. Any technical solutions formed by equivalent transformation or equivalent replacement should fall within the protection scope of the claims of the present invention.
