Description

Technical Field

[0001] This invention relates to a peeler and a quick disassembly and assembly method for the walking drive of tracked construction machinery, belonging to the field of construction machinery. Background Technology

[0002] Tracked walking systems are widely used in construction machinery, especially in harsh and severe working conditions, and have high reliability and stability.

[0003] Tracked mobility systems generally consist of large structural components and transmission components. The large structural components include a central frame and left and right traveling beams, which can be either integrally welded or assembled. The transmission components include tracks, idlers, track rollers, support rollers, drive sprockets, tensioning devices, and a speed reducer. The drive sprockets and speed reducer are assembled together, collectively referred to as the mobility drive. The speed reducer drives the drive sprockets to rotate, and the drive sprocket teeth move the tracks to propel the vehicle.

[0004] The drive wheel and track are meshed, which makes it difficult to disassemble and repair the drive system. Currently, service personnel typically remove the track links by destructive means and then remove the drive system, requiring the replacement of the track links. This process is difficult and costly. Summary of the Invention

[0005] To address the problems existing in the prior art, the present invention provides a quick disassembly and assembly method for a stripper and a tracked engineering machinery walking drive, which enables quick disassembly and assembly of the walking drive without damaging the track links.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] In a first aspect, the present invention discloses a stripper, the stripper comprising:

[0008] The support plate is arc-shaped;

[0009] Two clamping devices are installed on the inner arc surface of the support plate. In use, the two clamping devices are respectively locked in the tooth gap of the drive wheel and fixed together with the wheel body of the drive wheel.

[0010] In some embodiments, the support plate has a shape that is low at both ends and high in the middle in the front-rear direction, and the ends are chamfered, so that the track can slide up or down the support plate when the walking drive is disassembled and assembled.

[0011] In some embodiments, the clamping device includes:

[0012] A curved plate is fixed to the support plate and forms a cavity between the curved plate and the support plate. The outer contour of the curved plate matches the shape of the space between the teeth of the drive wheel.

[0013] A pair of opposing clamping plates, one part of which is located in the bent plate and the other part is located outside the bent plate, the clamping plates can slide on the bent plate, and the clamping plates on both sides can move towards each other or away from each other to clamp and release the wheel body;

[0014] Two adjusting components are mounted on the curved plate and connected to the corresponding clamping plates, and the clamping plates are moved by adjusting the components.

[0015] In some embodiments, the bottom of the curved plate is provided with a long sliding groove, which moves back and forth along the long sliding groove when the clamping plate clamps or releases the drive wheel; a guide plate is fixed on each of the left and right inner arc surfaces of the curved plate, and there is a slot on each of the left and right sides of the upper part of the clamping plate, which is respectively locked onto the corresponding guide plate, and the clamping plate slides through the cooperation of the slot and the guide plate.

[0016] In some embodiments, a stiffener is fixed at each of the front and rear ends of the bent plate, and the stiffener has a through hole; the adjusting component is an adjusting rod with threads, the diameter of the through hole on the stiffener is larger than the diameter of the adjusting rod, the adjusting rod passes through the through hole on the stiffener and is screwed into the threaded hole on the clamping plate, and the clamping plate moves back and forth by rotating the adjusting rod.

[0017] In some embodiments, a washer is placed between the head boss of the adjusting rod and the rib plate, and a retaining ring is inserted into the groove of the adjusting rod near the inner side of the rib plate. The adjusting rod is limited by the washer and retaining ring arranged on both sides of the rib plate, so that the adjusting rod cannot move axially and can only rotate.

[0018] In some embodiments, the end of the adjusting rod has a groove that engages with a retaining ring to prevent the clamp from dislodging from the adjusting rod.

[0019] In some embodiments, a knob is installed at the head of the adjusting rod, and the inner diameter of the knob is interference-fitted with the diameter of the adjusting rod; when the knob is rotated, the clamp moves back and forth along the thread on the adjusting rod.

[0020] In some embodiments, the clamping plate is wider at the top and narrower at the bottom, with the upper part locked inside the bent plate and the lower part extending out of the bent plate through a groove. The lower end of the clamping plate is bent to lock the drive wheel.

[0021] Secondly, this invention discloses a method for quick assembly and disassembly of the walking drive mechanism for tracked engineering machinery:

[0022] The drive system includes drive wheels and a reducer. Disassembly method:

[0023] S01: Raise the traveling beam, loosen the tension oil valve, and release all the oil in the tension cylinder. At this time, the track no longer bears tension and is in a naturally relaxed state.

[0024] S02: Push the guide wheel inwards towards the travel beam to fully loosen the tracks.

[0025] S03: Install the stripper at the part where the drive wheel and track are not engaged, and rotate the knobs on both sides of the stripper to firmly fix the stripper on the drive wheel.

[0026] S04: After inserting a stripper, rotate the drive wheel clockwise to slowly move the stripper between the drive wheel and the track. At this time, the stripper will support the track and peel the track off the drive wheel teeth.

[0027] S05: Repeat steps S03-S04, sequentially placing the stripper at the non-engaged section between the drive wheel and the track until the track is completely stripped from the drive wheel teeth. Multiple strippers should be spaced at equal intervals.

[0028] S06: Remove the fixing bolts between the travel drive and the travel beam, lift the travel drive, and slowly remove it from the travel beam.

[0029] Installation method of walking drive:

[0030] N01: Fix multiple strippers at equal intervals on the drive wheel, in the same quantity and position as during dismantling.

[0031] N02: Lift the travel drive and slowly move it into the travel beam for bolt fixing.

[0032] N03: Align the loose tracks one by one along the support plates on the stripper.

[0033] N04: Rotate the drive wheel counterclockwise to move the stripper to the part where the drive wheel and track are not engaged. Rotate the knobs on both sides of the stripper to remove the stripper from the drive wheel.

[0034] N05: Repeat N04 to remove all strippers and allow the drive wheels to mesh properly with the tracks.

[0035] N06: Inject grease into the tension cylinder through the tension valve, push the guide wheel forward, and slowly lift the entire track.

[0036] Beneficial effects of this invention:

[0037] The quick disassembly and assembly method for the stripper and tracked construction machinery drive provided by this invention is applicable to various working conditions and can quickly replace the drive without damaging the tracks, effectively reducing spare parts costs, service and maintenance time and costs.

Therefore, they should not be construed as limiting this invention.

[0055] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0056] A method for quick disassembly and assembly of the drive mechanism for tracked engineering machinery, which utilizes a special equipment peeler 1, will be described in detail below:

[0057] like Figures 3-9 As shown, the peeler 1 used in this example has a symmetrical structure, with a clamping device on each of the left and right sides. The two clamping devices have the same structure. The two clamping devices are welded to the top support plate 101 of the peeler 1 as a whole.

[0058] Further options: such as Figure 3 As shown, the support plate 101 is arc-shaped on both sides with chamfered ends to facilitate the sliding of the track 3. The support plate 101 is low at both ends and high in the middle in the front-back direction, which facilitates the sliding of the track 3 onto or off the support plate 101 when the walking drive is disassembled or assembled.

[0059] Further options: such as Figure 4 , Figure 5 , Figure 7As shown, the clamping device consists of a bending plate 102, a guide plate I 103, a guide plate II 104, a stiffening plate 105, a clamping plate 106, a retaining ring 107, an adjusting rod 108, a retaining ring 109, a washer 110, and a knob 111.

[0060] Further options: such as Figure 5 , Figure 7 As shown, the external structure of the curved plate 102 is similar to the external structure of the space between the teeth of the drive wheel 2. When placing the peeler 1, the curved plate 102 parts of the two clamping devices are respectively placed between the teeth of the drive wheel 2, separated by one tooth. It can also be designed to be separated by multiple teeth or not separated by any teeth, depending on the actual situation. The bottom of the curved plate 102 is provided with a long sliding groove, which will move back and forth along the long sliding groove when the clamping plate 106 clamps or releases the drive wheel 2. A stiffening plate 105 is welded to each of the front and rear ends of the curved plate 102, and the stiffening plate 105 has through holes. Guide plate I103 and guide plate II104 are welded to the left and right inner sides of the curved plate 102.

[0061] Further options: such as Figure 5 , Figure 8 As shown, two clamping plates 106 are symmetrically placed inside the clamping device. Each clamping plate 106 has a slot 1062 on its upper left and right sides, which respectively engages with guide plate I103 and guide plate II104, allowing for back-and-forth sliding. The upper part of the clamping plate 106 has a threaded hole 1061. The clamping plate is wider at the top and narrower at the bottom. The upper part is engaged within the bent plate 102, and the lower part extends out of the bent plate 102 through a groove. The lower end of the clamping plate 106 is bent 1063 to hold the drive wheel 2.

[0062] Further options: such as Figure 7 , Figure 9 As shown, the adjusting rod 108 has threads, passes through a through hole in the rib plate 105, and is screwed into a threaded hole in the clamping plate 106. The diameter of the through hole in the rib plate 105 is larger than the diameter of the adjusting rod 108. The end of the adjusting rod 108 has a groove 1081 that engages with a retaining ring 107, preventing the clamping plate 106 from disengaging from the adjusting rod 108. A washer 110 is placed between the head boss 1083 of the adjusting rod 108 and the rib plate 105. A retaining ring 109 engages with the groove 1082 near the inner side of the adjusting rod 108 close to the rib plate 105, thus limiting the adjusting rod 108 to rotation only and preventing it from moving forward or backward. The end of the adjusting rod 108 has a chamfer for easy screwing.

[0063] Further options: such as Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7As shown, a knob 111 is mounted on the head of the adjusting rod 108. The inner diameter of the knob 111 is interference-fitted with the diameter of the adjusting rod 108. When the knob 111 is rotated, the clamping plate 106 moves back and forth along the thread on the adjusting rod 108. At this time, the slot 1062 on the clamping plate 106 slides on the guide plate I103 and the guide plate II104.

[0064] The following is combined Figure 1 , Figure 2 , Figure 10 , Figure 11 A detailed explanation of a quick disassembly and assembly method for the walking drive of tracked construction machinery is provided:

[0065] The walking drive system includes drive wheels 2 and a reducer 4. Disassembly method:

[0066] S01: Raise the traveling beam 5 so that the track is off the ground, loosen the tension oil valve 6, usually 0.5-1 turn is enough, release all the oil in the tension cylinder, at this time the track 3 no longer bears tension force and is in a naturally relaxed state;

[0067] S02: Push the guide wheel 7 into the travel beam 5. Since there is no grease in the tension cylinder, the piston retracts into the cylinder, and the guide wheel 7 can be pushed back into the travel beam 5. At this time, the track 3 is completely relaxed and sags.

[0068] S03: Only a portion of the drive wheel 2 and track 3 are engaged. The stripper 1 is installed in the non-engaged portion, i.e., the space between the track roller 8 and the drive wheel 2. Rotate the stripper knob 111 to increase the distance between the two clamping plates 106 of the stripper 1, then place it on the drive wheel 2. The two clamping devices are respectively engaged in the gaps between the wheel teeth. In this example, the two clamping devices of the stripper 1 are spaced one wheel tooth apart. After stable placement, rotate the knob 111 to move the clamping plates 106 towards the drive wheel 2, so that the lower bend 1063 of the clamping plates 106 engages with the wheel body of the drive wheel 2. Continue tightening to firmly fix the stripper 1 on the drive wheel 2. Figures 10-11 As shown.

[0069] S04: After placing a stripper 1, rotate the drive wheel 2 clockwise to make the stripper 1 slowly enter between the drive wheel 2 and the track 3. At this time, the track links of the track 3 will slowly climb up the stripper 1 along the support plate 101 of the stripper 1, thus completely separating from the teeth of the drive wheel 2.

[0070] S05: Repeat operations S03-S04, sequentially placing the stripper 1 at the non-engaged parts of the drive wheel 2 and track 3 until the track 3 is completely stripped from the teeth of the drive wheel 2. In this example, one stripper 1 is placed every two teeth, for a total of three strippers 1.

[0071] S06: Remove the fixing bolts between the travel drive and the travel beam 5, lift the travel drive, and slowly remove it from the travel beam 5. During the movement, the track 3 slides on the support plate 101 of the stripper 1, sliding from the higher middle part of the support plate 101 to the lower side. Finally, the travel drive is completely removed.

[0072] Finally, loosen the peeler 1 and remove it from the drive wheel.

[0073] Installation method of walking drive:

[0074] N01: Rotate the peeler knob 111 to increase the distance between the two clamping plates 106 of the peeler 1, then place it on the drive wheel 2. The two clamping devices should be engaged in the gaps between the wheel teeth. After stable placement, rotate the knob 111 to move the clamping plates 106 towards the drive wheel 2, causing the lower bend 1063 of the clamping plates 106 to engage with the drive wheel 2. Continue tightening to firmly fix the peeler 1 onto the drive wheel 2. Figures 10-11 As shown. In this example, three peelers 1 are fixed at equal intervals on the drive wheel 2. In this example, they are spaced two teeth apart. The number and position of the peelers 1 are the same as those in the above removal.

[0075] N02: Move the loosened track 3 to one side, leaving enough space for installation. Lift the travel drive and slowly move it into the travel beam 5, then fix it with bolts.

[0076] N03: Slowly straighten the loose track links of track 3 along the support plate 101 on the peeler 1. Because the support plate 101 is low on both sides and high in the middle, track 3 can easily slide onto the support plate 101.

[0077] N04: Rotate the drive wheel 2 counterclockwise to move the stripper 1 to the part where the drive wheel 2 and the track 3 are not engaged, that is, the space between the track roller 8 and the drive wheel 2. Rotate the knobs 111 on both sides of the stripper 1 to release the clamp 106 from the drive wheel 2 and remove the stripper 1 from the drive wheel 2.

[0078] N05: Repeat N04 to remove all strippers 1 and allow drive wheels 2 to mesh normally with tracks 3.

[0079] N06: By injecting grease into the tension cylinder through the tension oil valve 6, the piston will push the guide wheel 7 forward, and the guide wheel 7 will slowly support the entire track 3.

[0080] Finally, lower the travel beam 5 to quickly replace the travel drive without damaging the tracks.

[0081] In summary, this invention discloses a stripper and a quick disassembly and assembly method for the drive mechanism of tracked engineering machinery. By adjusting the tensioning device and installing multiple strippers on the drive wheel, the track can be completely detached from the drive wheel teeth, enabling convenient and quick disassembly and assembly of the drive mechanism without disassembling the track. This method can effectively reduce the cost of track spare parts and reduce market service and maintenance time and costs.
