Description

Technical Field

[0001] The utility model belongs to the technical field of industrial gas engines, and in particular relates to a combined tool for assembling a Titan250 backrest wheel. Background Art

[0002] A gas engine is a type of internal combustion engine that generates power and work by burning natural gas. It can be used to propel cars and ships, or it can be used to drive generators to generate electricity after burning. Its advantage is that it is cleaner and more environmentally friendly than diesel or gasoline engines. Gas engines can replace diesel and gasoline engines and are now widely used in public transportation, oil field power generation and other fields. Among them, the Titan250 movement has a power of up to 30,000HP, a rated speed of 10,500RPM, and a weight of up to 19 tons. It needs to be connected to the backrest wheel to work. The backrest wheel is connected to the output shaft through internal and external splines, and is fixed to the output shaft with three bolts to transmit power to the outside. Due to the high speed and high power of the movement, the matching accuracy of the backrest wheel and the output shaft is very high.

[0003] Since the spline fit between the backrest wheel and the output shaft has a certain interference when cold, the backrest wheel is usually heated to 160 degrees during installation, and then lifted with the help of a hoist. The inner spline of the backrest wheel is aligned with the outer spline of the output shaft in the shortest possible time, and then the backrest wheel is pushed onto the output shaft. Due to the special structure of the backrest wheel, it is difficult to lift the backrest wheel flat using only a sling, which makes it difficult to align the inner and outer splines during installation, requiring multiple attempts. Multiple attempts cause the temperature of the backrest wheel to drop. Even if the inner and outer splines are aligned, it is difficult to manually push the backrest wheel onto the shaft, resulting in assembly failure. Utility Model Content

Of course, they are only examples, and the purpose is not to limit the embodiments of the present utility model. In addition, the embodiments of the present utility model can repeat reference numbers and / or reference letters in different examples, and this repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed.

[0034] In order to better understand the purpose, structure and function of the utility model, the utility model is further described in detail below with reference to the accompanying drawings, a combination tool for assembling the backrest wheel of Titan250.

[0035] like Figure 1-Figure 8 As shown, the utility model is a combination tool for assembling Titan250 backrest wheels, including an adjustment unit 100 for fixing the overall sling, and a connection unit 200 installed at the lower end of the adjustment unit 100, and the connection unit 200 is movably installed at the lower end of the adjustment unit 100.

[0036] The connecting unit 200 includes a clamping part 300 movably installed on one side of the lower end of the adjusting unit 100 and a hanging part 400 movably installed on the other side of the lower end of the adjusting unit 100. The clamping part 300 and the hanging part 400 are respectively arranged on both sides of the backrest wheel 700 for fixation, and then adjusted through the adjusting unit 100 to align with the output shaft of the Titan250 industrial gas engine.

[0037] The clamping part 300 includes a clamping arm 310 for fixing the circular sleeve of the backrest wheel and a positioning piece 320 installed at the upper end of the clamping arm 310 for installing the clamping arms 310 on both sides. The clamping arm 310 is movably installed on both sides of the positioning piece 320 by bolts. A lifting piece 340 for adjusting the opening and closing angle of the clamping arm 310 is slidably installed in the middle part of the clamping arm 310. The lifting piece 340 is slidably installed in a movable groove 330 penetrating the middle part of the clamping arm 310 through lifting rods 350 movably installed on both sides. An opening and closing screw 360 for adjusting the position of the lifting piece 340 is threadedly installed on the upper end of the lifting piece 340. The opening and closing screw 360 passes through the positioning piece 320 through a bearing and is installed, and is driven to rotate by a driving motor 370 installed on the upper end of the positioning piece 320.

[0038] The hanging part 400 includes a gantry 410 for clamping and fixing one side of the backrest wheel 700 and a positioning bolt 420 movably inserted at the lower end of the gantry 410. The positioning bolt 420 is installed through a through hole of a flange on one side of the upper end of the backrest wheel 700.

[0039] After lifting the connection unit 200, lower it to the top of the backrest wheel 700, lower the lifting device, and the clamp part 300 covers the left side of the backrest wheel 700. The hanging part 400 is connected to the right side of the backrest wheel 700 through the top flange hole of the right side flange of the backrest wheel 700. Lift the lifting device, and comprehensively adjust the hanging part 400 and the upper adjustment unit 100 to keep the backrest wheel 700 level after lifting. In this way, the initial adjustment of the connection unit 200 is completed.

[0040] After heating the backrest wheel 700 to about 160 degrees, connect it to the connection unit 200 that has completed the initial adjustment. Since the connection position between the backrest wheel 700 and the connection unit 200 is fixed, the lifting fixture that has completed the initial adjustment does not need to be adjusted again to make the backrest wheel 700 horizontal after lifting. Transfer the backrest wheel 700 to the output shaft position of the Titan250 industrial gas engine, swing the backrest wheel 700, align the inner and outer splines, push the backrest wheel 700 to the output shaft installation position, tighten the shaft end locking bolts, and complete the assembly.

[0041] Furthermore, the upper ends of the clamping part 300 and the hanging part 400 are movably mounted with universal joints 500 for adjusting their positions, which can achieve front-to-back and left-to-right swing, and facilitate the alignment of the backrest wheel 700 with the inner and outer splines of the output shaft.

[0042] Furthermore, a double-headed screw 430 for pulling the portal frame 410 is threadedly installed on the upper end of the portal frame 410, and the upper end of the double-headed screw 430 is threadedly installed on the lower end of the connecting frame 450. The double-headed screw 430 is threadedly connected to the connecting frame 450 and the portal frame 410 respectively, and the thread directions are opposite. An adjusting member 440 is fixedly installed in the middle of the double-headed screw 430 for facilitating rotational adjustment of the double-headed screw 430. The double-headed screw 430 can be rotated by rotating the adjusting member 440, and then the double-headed screw 430 with opposite threads on both sides drives the connecting frames 450 and the portal frame 410 on both sides to move toward the middle, and then the relative distance of the portal frame 410 can be adjusted, and the position of the portal frame 410 can be adjusted to facilitate the adaptation to the size of the backrest wheel 700.

[0043] Furthermore, a swivel foot 380 for fixing the circular sleeve portion of the back wheel 700 is movably installed on the inner side of the lower end of the clamp arm 310. The swivel foot 380 is connected to the clamp arm 310 via a torsion spring and a mounting shaft. When fixing the back wheel 700, the swivel foot 380 can be fixed at the end of the circular sleeve portion of the back wheel 700, so as to facilitate matching with back wheels 700 of different diameters. The rotatably arranged swivel foot 380 can be more closely fitted to the back wheel 700 for clamping, which is convenient for clamping operations.

[0044] Furthermore, a telescopic pile 390 is threadedly installed in the middle of the rotating foot 380 for auxiliary fixation of the internally clamped items. The end of the telescopic pile 390 is rotationally adjusted by an auxiliary tool. When fixing the backrest wheel 700 with a smaller diameter, the threaded telescopic pile 390 can be adjusted to extend to further fix the backrest wheel 700.

[0045] A guide rod 600 is movably inserted at the upper end of the gantry 410, and the guide rod 600 passes through the hole arrangement at the upper end of the gantry 410. A rotating part 610 for facilitating the operation of the guide rod 600 is fixedly arranged at one end of the guide rod 600, and a threaded portion 620 for installing the guide rod 600 is arranged at the other end of the guide rod 600. A threaded groove 460 for fixing the guide rod 600 is provided on one side of the gantry 410, and the threaded groove 460 matches the thread of the threaded portion 620. A fastener 710 for docking and mounting with the output shaft of the Titan250 industrial gas engine is provided on one side of the backrest wheel 700, and a through hole is arranged at the upper end of the fastener 710 for passing through the guide rod 600 for auxiliary fixation.

[0046] When assembling the back wheel 700, three guide rods 600 are threadedly installed, and the outer diameter of the guide rod 600 is consistent with the thread of the fastening bolt of the back wheel 700. The three through holes of the fastener 710 on the back wheel 700 pass through the guide rod 600 in sequence, thus ensuring that the threaded hole at the end of the shaft is aligned with the through hole of the back wheel 700. The guide rod 600 is installed in the three threaded holes on the end face of the output shaft, and the two cooperate with each other to ensure the installation accuracy and quality of the back wheel 700. After the back wheel 700 is installed on the output shaft, the three threaded holes at the end of the output shaft are misaligned with the three through holes on the back wheel 700. After the back wheel 700 is installed in place on the output shaft, the back wheel 700 is fixed to the output shaft by three bolts to avoid misalignment between the threaded hole and the through hole, and the fastening bolt cannot be installed, resulting in unreliable positioning of the back wheel 700.

[0047] Furthermore, the three lengths of the guide rod 600 decrease in sequence, so as to facilitate passing through the through hole of the backrest wheel 700.

[0048] The adjustment unit 100 includes a lifting box 110 for installation and a slot 120 opened inside the lifting box 110 for limiting the connection unit 200. A transmission member 150 for moving and adjusting the connection unit 200 is installed on the upper end of the connection unit 200. The transmission member 150 is slidably installed inside the slot 120. The transmission member 150 is threadedly installed on the upper end of a transmission screw 130 arranged inside the slot 120. A lifting member 140 is fixedly installed in the middle of the lifting box 110. The lifting box 110 is lifted by a crane, and the thread directions of the transmission screws 130 on both sides of the lifting member 140 are opposite.

[0049] During the debugging process of the connection unit 200, the driving motor 370 can be used to drive the transmission screw 130 to rotate, thereby driving the transmission member 150 threadedly installed at the upper end to move, and then the distance between the clamp part 300 and the hanger part 400 can be adjusted, making it more flexible to use.

[0050] The working principle of a combination tool for assembling a Titan250 backrest wheel is as follows: after heating the backrest wheel 700 to about 160 degrees, connect it to the connection unit 200 that has completed the initial adjustment. Since the connection position between the backrest wheel 700 and the connection unit 200 is fixed, the lifting device that has completed the initial adjustment does not need to be adjusted again to make the backrest wheel 700 horizontal after lifting. Transfer the backrest wheel 700 to the output shaft position of the Titan250 industrial gas engine, swing the backrest wheel 700, align the inner and outer splines, push the backrest wheel 700 to the output shaft installation position, tighten the shaft end locking bolts, and complete the assembly.
