Description

Technical Field

[0001] This invention relates to a mechanical device and method for disassembling track pins of tracked vehicles, belonging to the field of track pin disassembly technology. Background Technology

[0002] The running gear of heavy-duty tracked vehicles typically consists of drive wheels, idler wheels, track rollers, carrier rollers, and tracks. The tracks not only support the entire machine but also drive it, playing a crucial role in the running gear system. Replacing track shoes and shipping the entire machine both require disassembling the track pins. To facilitate the disassembly of these track pins, heavy-duty tracked vehicles are designed with threaded holes and screws at the ends of the pins. However, during operation, factors such as vibration can cause these screws to loosen and fall out, leading to the threaded holes becoming clogged with mud and sand, or corroding, resulting in threaded hole failure and making pin disassembly difficult. Summary of the Invention

When disassembling a track consisting of multiple track plates connected by a single track pin, the disassembly mechanism is arranged on one side of the track for disassembly.

[0005] In some embodiments, the housing is divided into a top seat and a base connected as one piece; the top seat has a slide rail inside, and the base has a track inside, the slide rail and the track are connected to form a mounting cavity for assembling the pusher component; the base is slidably connected to the support frame, and when the support frame is fixed on the track, the base can drive the top seat to move along the axial direction of the track pin.

[0006] In some embodiments, the pushing component includes: A power component is installed in the slide rail, and the transmission conversion component is connected to the power component; A push rod, the top of which is connected to the power component, and the bottom of which extends to the bottom of the track; A cylindrical shaft is arranged in the track and can move axially in the track; the power component drives the push rod to move, and the push rod in turn drives the cylindrical shaft to push the track pin.

[0007] In some embodiments, the jacking component further includes an auxiliary shaft, which is arranged coaxially and side-by-side with the cylindrical shaft in use to extend the disassembly stroke of the track pin.

[0008] In some embodiments, the power component includes: A threaded shaft passes through the slide rail and is rotatably supported on the top seat by a bearing; one end of the threaded shaft protrudes from the top seat and is used to connect to the transmission conversion component. A threaded slider is arranged in the slide rail and mounted on the threaded shaft, forming a helical pair between them. The top surface of the push rod is fixed to the bottom surface of the threaded slider.

[0009] In some embodiments, the transmission conversion component includes a hexagonal head and a stepped shaft connected as one piece; one end of the stepped shaft is provided as a cuboid structure, which is inserted into a square groove on the end face of a threaded shaft extending from the top seat; the hexagonal head is connected to a rotating shaft that provides external power to the transmission conversion component.

[0010] In some embodiments, the support frame includes: A pair of opposing baffles are positioned on either side of the track during use; Multiple long shafts, the length of which is greater than the width of the track, pass through two baffles; the disassembly mechanism is slidably connected to a portion of the long shafts; Multiple locking components are configured to secure and release the baffle from the long shaft, thereby fastening the support frame to the track or removing the support frame from the track.

[0011] In some embodiments, both baffles are provided with a plurality of coaxially arranged circular holes, and the outer side of one baffle is provided with a threaded seat coaxially arranged at each circular hole; both ends of the long shaft are provided with external threads, and one end of the long shaft passes through the circular holes on the two baffles and is screwed into the threaded seat; the locking component is a wing nut, which is screwed onto the other end of the long shaft.

[0012] In some embodiments, the baffle has an overall structure that is wider at the top and narrower at the bottom.

[0014] Secondly, the present invention provides a method for disassembling track pins of tracked vehicles: When disassembling the track pins that connect multiple track plates via track pins arranged on opposite sides, first remove the bolts and nuts that axially limit the track pins on the track plates. Then, embed the disassembly mechanism into the assembly gap between the two track plates, and use a support frame to fix the disassembly mechanism to the track plate. Transmission conversion components transmit external power to the pushing component in the disassembly mechanism, which pushes the track pin to move axially, thereby pushing the track pin out of the pin hole. At this point, only the pin on one side of the track has been removed. To disassemble the pin on the other side, simply adjust the installation direction of the disassembly mechanism, retighten the support frame, and repeat the above steps to disassemble the pin on the other side. When disassembling the track pins of a track consisting of multiple track plates connected by a single track pin, the disassembly mechanism is installed on one side of the track rail. The disassembly mechanism is fixed to the track plate using a support frame. External power is transmitted to the jacking component in the disassembly mechanism through a transmission conversion component. The jacking component pushes the track pin to move axially, thereby pushing the track pin out of the pin hole.

[0015] Beneficial effects of this invention: This invention enables the disassembly of track pins in heavy-duty tracked vehicles. Therefore, there is no need to design threaded holes at the ends of the pins for disassembly, fundamentally solving the problems of loose screws and threaded holes that prevent the pins from being disassembled.

[0020] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

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

[0022] 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.

[0023] Existing tracked vehicles consist of multiple track plates hinged together by track pins. Considering vehicle transport and replacement of track plates or pins due to malfunction, the pin ends are designed with threaded holes for disassembly. To prevent these holes from becoming clogged by mud or corrosion, screws are typically installed. However, during vehicle operation, due to vibration and other factors, these screws are prone to loosening and falling off, leading to market feedback of loose screws and threaded holes being exposed and clogged by mud or corrosion. This invention provides a mechanical device and method for disassembling track pins in tracked vehicles. This method not only effectively and efficiently disassembles track bolts but also eliminates the need for designing and machining the threaded holes, thus reducing the manufacturing cost of the pins to some extent.

[0024] like Figure 1 , Figure 7 , Figure 9As shown, a track pin disassembly mechanism 21 for tracked vehicles includes a support frame 2, a disassembly mechanism 1, and a transmission conversion component 3. The support frame 2 is configured to fix and release the track. The disassembly mechanism 1 includes a housing and a pushing component located within the housing. The housing is mounted on the support frame 2, and the two are movably connected, enabling position and orientation adjustment of the disassembly mechanism 1. The pushing component contacts the end face of the track pin 23 to push the track pin 23 out of the pin hole. The transmission conversion component 3 is connected to the pushing component to transmit external power to the pushing component, thereby realizing the disassembly function of the track pin 23. When disassembling the track pins of multiple track plates 22 connected by track pins 23 arranged opposite to each other on both sides, the disassembly mechanism 1 is embedded in the assembly gap 27 between two track plates 22 for disassembly. When disassembling the track pins of multiple track plates 22 connected by a single track pin 23, the disassembly mechanism 1 is arranged on one side of the track track for disassembly.

[0025] The specific structure of the aforementioned shell will be further explained below.

[0026] like Figure 2 , Figure 3 As shown, the housing includes a top seat 26 and a base 9 connected as one piece; the top seat 26 has a slide 4 inside, and the base 9 has a track 12 inside. The slide 4 and the track 12 are connected to form an installation cavity for assembling the pusher component; the base 9 is slidably connected to the support frame 2. When the support frame 2 is fixed on the track, the base 9 can drive the top seat 26 to move along the axial direction of the track pin 23.

[0027] It should be noted that the top seat 26 is welded together from the middle seat and the bearing seats 8 and 15 on both sides, and the base 9 is composed of a T-shaped plate and multiple sliders 13 welded to the T-shaped plate; the top seat 26 and the base 9 are welded together.

[0028] The following provides a further explanation of the specific structure of the aforementioned jacking component.

[0029] like Figure 2 , Figure 3 As shown, the jacking component includes a power component, a push rod 10, and a cylindrical shaft 11; the power component is installed in the slide rail 4, and the transmission conversion component 3 is connected to the power component; the top of the push rod 10 is connected to the power component, and its bottom extends to the bottom of the track 12; the cylindrical shaft 11 is arranged in the track 12 and can move axially in the track 12; the power component drives the push rod 10 to move, and the push rod 10 then drives the cylindrical shaft 11 to jack the track pin 23.

[0030] Further options, such as Figure 1 , Figure 2As shown, the jacking component also includes an auxiliary shaft 25. In use, the auxiliary shaft 25 is arranged coaxially and side by side with the cylindrical shaft 11 to extend the disassembly stroke of the track pin 23.

[0031] It should be noted that the auxiliary shaft 25 is mainly used to increase the disassembly stroke of the track pin 23. Whether the auxiliary shaft 25 is used for disassembly operation depends on the disassembly stroke required for the track pin 23 to be disassembled.

[0032] The specific structure of the aforementioned power components will be further explained below.

[0033] like Figure 2 , Figure 3 As shown, the power component includes a threaded shaft 7 and a threaded slider 5. The threaded shaft 7 passes through the slide rail 4 and is rotatably supported on the top seat 26 by the bearing 6. One end of the threaded shaft 7 passes through the top seat 26 and is used to connect the transmission conversion part 3. The threaded slider 5 is arranged in the slide rail 4 and is mounted on the threaded shaft 7, forming a helical pair between the two. The top surface of the push rod 10 is fixed to the bottom surface of the threaded slider 5.

[0034] It should be noted that, as Figure 2 , Figure 3 As shown, the bearing 6 is installed in the bearing housings 8 and 15 of the top seat 26. Through the bearings 6 on both sides, the threaded shaft 7 can rotate circumferentially in the top seat 26. After the threaded shaft 7 rotates, it drives the threaded slider 5 to move axially, which in turn drives the push rod 10 to move axially.

[0035] The specific structure of the aforementioned transmission conversion component will be further explained below.

[0036] like Figure 2 , Figure 6 As shown, the transmission conversion component 3 includes a hexagonal head and a stepped shaft connected as one piece; one end of the stepped shaft is set as a cuboid structure, which is inserted into a square groove on the end face of the threaded shaft that passes through the top seat 26; the hexagonal head is connected to the rotating shaft that provides external power to the transmission conversion component 3.

[0037] It should be noted that the above is only a preferred embodiment of the transmission conversion component, and the actual design is not limited to the structure described above. For example, one end of the stepped shaft can also be designed as a triangular structure, as long as the structure can prevent relative rotation between the transmission conversion component and the threaded shaft; the hexagon can also be designed as a square head, as long as the structure can be connected to the shaft that provides external power.

[0038] The following provides a further explanation of the specific structure of the aforementioned support frame.

[0039] like Figure 4As shown, the support frame 2 includes a pair of opposing baffles 16 and 18, a plurality of long shafts 17, and a plurality of locking components; the two baffles 16 and 18 are arranged on both sides of the track when in use; the length of the long shaft 17 is greater than the width of the track, and the long shaft 17 passes through the two baffles 16 and 18; the disassembly mechanism 1 is slidably connected to a portion of the long shaft 17; the plurality of locking components are configured to fix and release the baffles 16 and 18 from the long shaft 17, thereby securing the support frame 2 to the track or removing the support frame 2 from the track.

[0040] Further options, such as Figure 4 , Figure 5 As shown, both baffles 16 and 18 are provided with multiple coaxially arranged circular holes. One of the baffles 16 has a threaded seat 20 coaxially arranged at each circular hole on its outer side. The long shaft 17 has external threads at both ends along its length. One end of the long shaft 17 passes through the circular holes on the two baffles 16 and 18 and is screwed into the threaded seat 20. The locking component is a wing nut 19, which is screwed onto the other end of the long shaft 17.

[0041] Further options, such as Figure 4 , Figure 5 As shown, the baffles 16 and 18 have an overall structure that is wider at the top and narrower at the bottom. Two long shafts 17 are symmetrically arranged between the upper parts of the two baffles 16 and 18, and one long shaft 17 is arranged between the lower parts of the two baffles 16 and 18. The housing is provided with multiple sliders 13, and the two long shafts 17 at the top are respectively inserted through several sliders 13. The sliders 13 and the long shafts 17 are fitted with a clearance.

[0042] It should be noted that the above is only a preferred embodiment of the baffle. In actual design, the baffle can also be designed as a structure with the same width at the top and bottom, with two long shafts between the upper and lower parts of the two baffles; or the baffle can be fastened with wing nuts on both sides without threaded seats.

[0043] Further options, such as Figure 1 , Figure 4 , Figure 5 As shown, a clearance opening is provided in the middle area of ​​the top of the baffles 16 and 18. The transmission conversion component 3 falls into the horizontal projection area of ​​the clearance opening, so that the shaft that provides external power to the transmission conversion component 3 can pass through the clearance opening and connect to the transmission conversion component 3.

[0044] As can be seen from the above, the mechanical device for disassembling track pins of tracked vehicles provided by the present invention is designed based on the principle of threaded transmission and translational sliding. External power is transmitted to the threaded shaft through a transmission conversion joint, and then the threaded slider and push rod move along the slide rail, pushing the cylindrical shaft to move axially until the track pin is pushed out, thereby realizing the disassembly of the track pin; wherein the external power is provided by an air gun, but is not limited to it.

[0045] The present invention provides a mechanical device for disassembling track pins of tracked vehicles. Based on the structural characteristics of tracks, the disassembly mechanism can be embedded in the gap in the middle of the track plate for disassembling the pins, or it can be arranged on one side of the track for disassembling the pins, thus realizing the function of multiple uses in one device.

[0046] The present invention provides a mechanical device for disassembling track pins of tracked vehicles, which makes full use of the track assembly gap space and uses an auxiliary shaft to increase the disassembly stroke of the track pins, thus greatly improving its applicability and scope of application.

[0047] This invention also provides a method for disassembling track pins of a tracked vehicle. Before introducing this disassembly method, let's first describe two different track structures. One type of track is composed of multiple track plates 22 connected by track pins 23 arranged opposite to each other on both sides. The track pins 23 and the pin holes have a clearance fit. Therefore, bolts and nuts (i.e., bolt and nut assembly 24 in the attached drawings) are installed at the ends of the track plates 22 to axially limit the track pins 23. Since the track pins 23 and the pin holes have a clearance fit, it is only necessary to push the track pins 23 out of the pin holes partially, and then manually remove them. Figure 8 As shown; another type of track is composed of multiple track plates 22 connected by a single track pin 23. The track pin 23 and the pin hole are interference fit, requiring the track pin 23 to be completely pushed out of the pin hole. Since the distance between the end face of the track pin 23 and the end face of the track is very long, there is enough space for the track pin 23 to move out of the pin hole. Therefore, the baffle on the side of the track plate 22 will not obstruct the axial movement of the track pin 23. Figure 10 As shown.

[0048] The following describes the usage method when the track has pins on both sides for assembly.

[0049] like Figure 7As shown, before installation and use, a comprehensive evaluation based on the required disassembly stroke of the pre-disassembly track pin shaft is needed to determine whether to use the auxiliary shaft 25. If it is to be used, first remove the bolts and nuts on the track plate 22 (i.e., the bolt and nut assembly 24 in the attached diagram), place the auxiliary shaft 25 into the hole coaxial with the track plate pin hole through the assembly gap 27 between the track plates 22, then embed the disassembly mechanism 1 onto the track plate 22, and then use the support frame 2 to install and fix the disassembly mechanism 1 onto the track plate 22, adjusting the wing screw. Tighten the support frame 2 with bolt 19 until it is stable; use an air gun and transmission adapter 3 to drive the threaded shaft 7 to rotate. Driven by the rotation of the thread, the threaded slider 5 moves along the slide rail 4 and drives the push rod 10 to move. Driven by the push rod 10, the cylindrical shaft 11 moves axially and pushes the track pin 23 out of the pin hole. At this time, only the pin on one side of the track is removed. To remove the pin on the other side, simply adjust the installation direction of the disassembly mechanism 1, re-tighten the support frame 2, and repeat the above steps to remove the pin on the other side.

[0050] The following describes the usage method when the track only requires a single pin for assembly.

[0051] like Figure 9 As shown, before installation and use, a comprehensive evaluation based on the required disassembly stroke of the pre-disassembled track pin is needed to determine whether to use the auxiliary shaft 25. If it is to be used, the auxiliary shaft 25 is placed on the track pin 23, and the disassembly mechanism 1 is installed on one side of the track, ensuring that the cylindrical shaft 11 is aligned with the track pin 23. The disassembly mechanism 1 is fixed to the track plate 22 using the support frame 2, and the wing bolt 19 is adjusted to tighten the support frame 2 until it is stable. The threaded shaft 7 is driven to rotate using the air gun and the transmission conversion connector 3. The threaded slider 5 moves along the slide rail 4 and drives the push rod 10 to move under the drive of the threaded rotation. The cylindrical shaft 11 moves axially under the drive of the push rod 10, thereby pushing the track pin 23 out of the pin hole.

[0052] In summary, this invention enables the disassembly of track pins in heavy-duty tracked vehicles. Therefore, there is no need to design threaded holes at the ends of the pins for disassembly, fundamentally solving the problems of loose screws and threaded holes that prevent the pins from being disassembled.

External power is transmitted to the jacking component in the disassembly mechanism through a transmission conversion component. The jacking component pushes the track pin to move axially, thereby pushing the track pin out of the pin hole.
