Description

Technical Field

[0001] This application belongs to the field of mechanical production technology, specifically relating to a track clamping device, a track assembly operation system, and a track machinery assembly line. Background Technology

[0002] When assembling the tracks with the underframe of the work machinery, the folded tracks need to be unfolded into a straight line, and then the underframe is placed on the tracks. The track plate at one end of the track is lifted so that the track wraps around the wheel edge of the underframe. Finally, the track plates at both ends of the track are connected to complete the track installation.

[0003] The tracks are quite heavy, making it nearly impossible to lay, wind, and lift them manually. Therefore, current technology typically requires the assistance of a crane. A crane hook is precisely aligned and hooked into the cleaning mounting hole in the center of the track plate to facilitate track laying and winding. When manually operating the lifting device to hook into the hole, the hook position must be repeatedly adjusted. This work method is labor-intensive and poses significant safety hazards. Especially when the chassis is placed on the tracks, the crane's working space is severely limited due to obstruction, greatly increasing the difficulty of operation. Utility Model Content

[0004] In view of the above-mentioned defects or deficiencies, this application provides a track clamping device, a track assembly operation system, and a track machinery assembly line, aiming to solve the technical problems of high dependence on manual labor and cumbersome operation in existing track assembly operations.

[0005] To achieve the above objectives, this application provides a track clamping device, wherein the track clamping device includes a main frame, a first clamping block, a second clamping block, and a drive mechanism; the main frame is provided with a track hook portion for hooking clean mounting holes for hooking track plates, the first clamping block and the second clamping block are symmetrically disposed on both sides of the track hook portion and can move toward each other in a relative direction, and the drive mechanism is used to drive the first clamping block and the second clamping block to move synchronously in a mirror image in a relative direction.

[0006] In this embodiment, the driving mechanism includes a first driving arm, a second driving arm, and a synchronous transmission assembly. The first driving arm and the second driving arm are movably mounted on the main frame and can move in opposite directions. A first clamping block is mounted on the first driving arm, and a second clamping block is mounted on the second driving arm. The synchronous transmission assembly is used to control the first driving arm and the second driving arm to move synchronously in a mirror image in opposite directions.

[0007] In this embodiment, the synchronous transmission assembly includes a first rack, a second rack, and an intermediate transmission gear. The first rack is disposed on the first drive arm and extends in a relative direction, the second rack is disposed on the second drive arm and extends in a relative direction, and the intermediate transmission gear is rotatably disposed on the main frame and meshes with the first rack and the second rack on opposite sides respectively.

[0008] In this embodiment, the drive mechanism further includes a power element, which is used to drive one of the first drive arm, the second drive arm, and the intermediate transmission gear to move.

[0009] In this embodiment, the power element is a hydraulic cylinder, which is disposed between the main frame and the first drive arm and is used to drive the first drive arm to reciprocate in a relative direction; or, the hydraulic cylinder is disposed between the main frame and the second drive arm and is used to drive the second drive arm to reciprocate in a relative direction.

[0010] In this embodiment, both the first clamping block and the second clamping block include a clamping portion extending downward from the bottom surface of the main frame. The clamping portion has a snap-fit ​​cavity for engaging with the side of the track plate. The openings of the snap-fit ​​cavity of the first clamping block and the openings of the snap-fit ​​cavity of the second clamping block are arranged facing each other.

[0011] To achieve the above objectives, this application also provides a track assembly operation system, wherein the track assembly operation system includes a moving device and the track clamping device described above, the main frame of the track clamping device is mounted on the moving device, and the moving device is at least capable of driving the main frame to move horizontally in a straight line.

[0012] In this embodiment, the mobile device is a ground-walking device or a mobile crane.

[0013] In this embodiment, the track assembly operation system also includes a remote control device, which is used to remotely control the moving device and the drive mechanism in the track clamping device.

[0014] To achieve the above objectives, this application also provides a tracked machinery assembly line, wherein the tracked machinery assembly line includes the track assembly operation system described above.

[0015] Through the above technical solution, the track clamping device provided in this application embodiment has the following beneficial effects: In use, first move the track clamping device to the track plate to be hooked, and place the first and second clamping blocks on both sides of the target track plate. Then, drive the first and second clamping blocks to synchronously mirror each other. Since the first and second clamping blocks retract at the same rate, when the first and second clamping blocks are fully retracted and clamp the target track plate, the track hook will align with the cleaning mounting hole at the center of the track plate, thus achieving automatic alignment of the track hook with the cleaning mounting hole.

[0016] In summary, the track clamping device in this embodiment can automatically align the track hook with the cleaning mounting hole when clamping the track plate, eliminating reliance on manual labor and reducing the labor intensity of workers. At the same time, this device is applicable to different models of track plates, greatly improving compatibility. In addition, when the track clamping device carries the clamped track plate for spreading and winding, the first clamping block, the second clamping block, and the track hook can form multi-point clamping of the track plate, ensuring that the track plate is firmly clamped and avoiding tilting that would affect the operation.

[0017] Other features and advantages of this application will be described in detail in the following detailed description section. Attached Figure Description

Detailed Implementation

[0020] The specific embodiments of this application will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this application.

[0021] The track clamping device of this application is described below with reference to the accompanying drawings.

[0022] Tracks are a key walking component of heavy-duty machinery (such as excavators and bulldozers), consisting of multiple patterned metal track plates, links, and hinged pins. Each track plate has a cleaning mounting hole in the center. These holes are primarily used to drain mud and water from the inside of the track when it is in motion. They also serve as hook points for traction during track assembly.

[0023] The current assembly process for tracks and underframes heavily relies on cranes to hook onto the holes to spread, move, and wind the tracks. However, this operating mode has significant drawbacks: manually positioning and operating the hook to precisely align the pins in the holes is labor-intensive and prone to accidents such as crushing injuries; especially after the underframe is placed on the spread tracks, its massive structure severely obstructs the view, and the working space below is extremely narrow, making it difficult for the hook to observe and accurately hook onto the obstructed mounting holes, resulting in low operating efficiency and a sharp increase in risk.

[0024] Therefore, this application provides a track clamping device, such as... Figure 1 As shown, the track clamping device includes a main frame 1, a first clamping block 21 and a second clamping block 22, and a drive mechanism.

[0025] The main frame 1 is provided with a track hook part 11 for hooking the cleaning mounting holes on the track plate 4.

[0026] The first clamping block 21 and the second clamping block 22 are symmetrically arranged on both sides of the track hook part 11, and the first clamping block 21 and the second clamping block 22 can move towards or away from each other in a relative direction.

[0027] The drive mechanism is used to drive the first clamping block 21 and the second clamping block 22 to move synchronously in a mirror image in a relative direction.

[0028] In use, firstly, move the track clamping device to the vicinity of the track plate 4 to be hooked, and place the first clamping block 21 and the second clamping block 22 on both sides of the target track plate 4, respectively. Then, drive the first clamping block 21 and the second clamping block 22 to synchronously mirror each other through the drive mechanism. Since the first clamping block 21 and the second clamping block 22 retract at the same rate, when the first clamping block 21 and the second clamping block 22 have fully retracted and clamped the target track plate 4, the track hook part 11 will align with the cleaning mounting hole at the center of the track plate 4, thus achieving automatic alignment between the track hook part and the cleaning mounting hole.

[0029] In summary, the track clamping device in this embodiment can automatically align the track hook 11 with the cleaning mounting hole when clamping the track plate, eliminating the reliance on manual labor and reducing the labor intensity of workers. At the same time, this device is applicable to different models of track plates 4, greatly improving compatibility. In addition, when the track clamping device carries the clamped track plate 4 for spreading and winding, the first clamping block 21, the second clamping block 22, and the track hook 11 can form multi-point clamping of the track plate 4, thereby ensuring that the track plate 4 is firmly clamped and avoiding tilting that would affect the operation.

[0030] like Figure 1As shown, to achieve synchronous mirror-driven operation of the first clamping block 21 and the second clamping block 22, in this embodiment, the driving mechanism may include a first driving arm 31, a second driving arm 32, and a synchronous transmission assembly 33. The first driving arm 31 and the second driving arm 32 are movably mounted on the main frame 1 and can move in opposite directions. The first clamping block 21 is mounted on the first driving arm 31, and the second clamping block 22 is mounted on the second driving arm 32. The synchronous transmission assembly 33 is used to control the mirror-driven synchronous linear movement of the first driving arm 31 and the second driving arm 32 in opposite directions. By driving the first driving arm 31 and the second driving arm 32 to move synchronously relative to each other, the first clamping block 21 and the second clamping block 22 can be synchronously moved closer to or farther away from each other.

[0031] like Figure 1 As shown, in this embodiment, the synchronous transmission component 33 can be a rack and pinion combination, that is, the synchronous transmission component 33 includes a first rack 331, a second rack 332 and an intermediate transmission gear 333. The first rack 331 is disposed on the first drive arm 31 and extends in opposite directions, the second rack 332 is disposed on the second drive arm 32 and extends in opposite directions, and the intermediate transmission gear 333 is rotatably disposed on the main frame 1 and meshes with the first rack 331 and the second rack 332 on opposite sides respectively.

[0032] Furthermore, the drive mechanism also includes a power element, which is used to drive one of the first drive arm 31, the second drive arm 32, and the intermediate transmission gear 333 to move.

[0033] like Figure 1 As shown, taking the first drive arm 31 driven by the power element as an example, when the first drive arm 31 is driven by the power element to move towards the side of the second drive arm 32 in the opposite direction, the movement of the first rack 331 will drive the intermediate transmission gear 333 to rotate, and the rotation of the intermediate transmission gear 333 will drive the second rack 332 and the second drive arm 32 to move towards the first drive arm 31. In this way, the first clamping block 21 and the second clamping block 22 can be mirror-synchronously brought together.

[0034] Similarly, when the power element drives the first drive arm 31 to move away from the second drive arm 32 in the opposite direction, the movement of the first rack 331 will drive the intermediate transmission gear 333 to rotate, and the rotation of the intermediate transmission gear 333 will drive the second rack 332 and the second drive arm 32 to move away from the first drive arm 31. In this way, the first clamping block 21 and the second clamping block 22 can be separated synchronously in mirror image.

[0035] like Figure 1As shown, in this embodiment, the power element can be a hydraulic cylinder 34. The hydraulic cylinder 34 can be disposed between the main frame 1 and the first drive arm 31 and used to drive the first drive arm 31 to reciprocate in the opposite direction. Alternatively, the hydraulic cylinder 34 can be disposed between the main frame 1 and the second drive arm and used to drive the second drive arm 32 to reciprocate in the opposite direction.

[0036] By using a single hydraulic cylinder 34 to drive the first drive arm 31 and the second drive arm 32 to move synchronously relative to each other, not only can the volume of the track clamping device be reduced, but the range of adjustment between the stroke of the hydraulic cylinder 34 and the distance between the clamping blocks can also be increased by 2:1. For example, if the stroke of the hydraulic cylinder 34 is 260mm, the distance adjustment range between the first clamping block 21 and the second clamping block can be 520mm. The small stroke hydraulic cylinder can achieve a large displacement of the clamping blocks, which can increase the space utilization of the device.

[0037] In this embodiment, the power element can also be a motor or electric motor that drives the intermediate transmission gear 333 to rotate. By driving the intermediate transmission gear 333 to rotate, the mirror-symmetric movement of the first drive arm 31 and the second drive arm 32 can also be achieved.

[0038] In this embodiment, the synchronous transmission component 33 can also be a combination of a traction rope and a rotating wheel. By setting the rotating wheel in a suitable position and then pulling it with the traction rope, the mirror-symmetrical movement of the first clamping block 21 and the second clamping block 22 can be achieved.

[0039] In this embodiment, the synchronous transmission component 33 can also be a screw and nut combination. By cooperating with two nuts with opposite directions of rotation and a screw with two rotations, the mirror symmetrical movement of the first clamping block 21 and the second clamping block 22 can also be achieved.

[0040] like Figure 1 As shown, in this embodiment, both the first clamping block 21 and the second clamping block include a clamping portion 2a extending downward from the bottom surface of the main frame 1. The clamping portion 2a has a locking cavity 2b for engaging with the side of the track plate 4. The openings of the locking cavity 2b of the first clamping block 21 and the locking cavity 2b of the second clamping block 22 are arranged facing each other. By designing the clamping portion 2a to extend downward, the track clamping device can easily clamp the track plate 4 from above. Furthermore, by providing the locking cavity 2b on the clamping portion 2a, the device can more firmly clamp the side of the track plate 4, reducing the possibility of the track plate 4 falling off the first clamping block 21 and the second clamping block 22.

[0041] To achieve the above objectives, this application also provides a track assembly system, wherein the track assembly system includes a moving device and a track clamping device according to the above description. The main frame 1 of the track clamping device is mounted on the moving device, and the moving device is capable of driving the main frame 1 to move horizontally in a straight line. The moving device facilitates control of the track device to move to a suitable position for clamping the track plates 4.

[0042] In this embodiment, the mobile device can be a ground-walking device (such as an RGV trolley) that walks on the ground. The ground-walking device drives the track clamping device to walk on the ground, thereby facilitating the track laying operation.

[0043] In this embodiment, the mobile device can also be a traveling crane. The traveling crane facilitates the track clamping device to lift and rewind the end track plate 4, so that it can be connected to the other end track plate 4.

[0044] In this embodiment, the track assembly operation system also includes a remote control device, which is used to remotely move the mobile device to a designated position. At the same time, the remote control device can also control the start and stop of the drive mechanism in the track clamping device.

[0045] The working principle of the track assembly system will be explained below by combining the track laying process and the installation process on the underframe.

[0046] After the folded track material is delivered to the assembly site, the binding wire of the track material is first cut, and then the ground walking device is controlled to move, so that the first clamping block 21 and the second clamping block 22 in the track clamping device on the ground walking device move to both sides of the end track plate 4.

[0047] The first clamping block 21 and the second clamping block 22 are brought together to clamp the track plate 4. During the clamping process, the track hook part 11 on the main frame 1 gradually aligns with the cleaning mounting hole. After the track hook part 11 is aligned with the cleaning mounting hole, it can be controlled to perform corresponding actions to hook the track plate 4. For example, it can extend into the cleaning mounting hole or open to tension and cooperate with the cleaning mounting hole. Of course, during track laying operations, the track hook part 11 can also be controlled not to move, and the track plate can be clamped only by the first clamping block 21 and the second clamping block 22.

[0048] Control the movement of the ground walking device to enable the track clamping device to carry the end track plates 4 and perform track laying operations. After track laying is completed, the track is laid in a straight line on the ground. Control the ground walking device and the track clamping device on the ground walking device to reset, completing the track laying.

[0049] When the track is wrapped around the wheel of the undercarriage and needs to be closed in a ring, the traveling crane moves another track clamping device to a position above the end track plate 4 lying on the ground, and then repeats the clamping action. After clamping, the track plate 4 is lifted and moved towards the track plate 4 at the other end of the track. During this movement, the multi-point clamping of the track plate 4 by the first clamping block 21, the second clamping block 22, and the track hook part 11 ensures that the track plate's posture remains unchanged, thus facilitating the alignment of the pin holes at both ends of the track plate. When the track plates at both ends need to be connected by pins, the first clamping block 21 and the second clamping block 22 need to be controlled to avoid each other. Before avoiding this, if... Figure 1 As shown, it is necessary to ensure that the track hook 11 is hooked in place.

[0050] After the pin holes of the two track plates are aligned and the clamping blocks avoid each other, the pins are struck with a copper hammer to connect the two track plates.

[0051] To achieve the above objectives, this application also provides a tracked machinery assembly line, wherein the tracked machinery assembly line includes the track assembly system described above.
