They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the present invention.

[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0029] See Figures 1 to 5The utility model discloses a flip clamp for an excavator walking frame, including a clamping seat 10 and a driving assembly. There are two clamping seats 10, and the two clamping seats 10 are opposite to each other and spaced apart to form a clamping space. Each clamping seat 10 is provided with two locking members 11 and at least two clamping members 12. The two locking members 11 are arranged at intervals and can approach or move away from each other along a first direction. At least two clamping members 12 are paired and spaced apart along a second direction and can approach or move away from each other along the second direction, wherein the first direction is perpendicular to the second direction; the specific driving assembly includes a first driving mechanism 20 and a second driving mechanism 30. The first driving mechanism 20 is used to drive a pair of clamping members 12 to approach or move away from each other, and the second driving mechanism 30 is used to drive the two locking members 11 to approach or move away from each other.

[0030] On the basis of the above structure, the first direction is the left and right direction of the clamping seat 10, and the second direction is the height direction of the clamping seat 10 as an example for explanation (eg Figure 2 As shown), in specific use, when the two clamping seats 10 are adjusted to the initial state, that is, the two locking members 11 on the clamping seats 10 are close to each other to the minimum distance, and the pair of clamping members 12 are away from each other to the maximum distance, at this time, the workpiece is transported to the clamping space between the two clamping seats 10, and the two clamping seats 10 are respectively at the center of gravity positions on both sides of the workpiece, and then the second driving mechanism 30 on each clamping seat 10 is started to drive the two locking members 11 on each clamping seat 10 to move away from each other until they respectively abut against the inner side of the center of gravity position of the workpiece, so as to limit the left and right displacement of the workpiece in the first direction;

[0031] After that, the first driving mechanism 20 on each clamping seat 10 is started to drive each pair of clamping members 12 to approach each other until they are against the upper and lower positions of the center of gravity of the workpiece and locked. In this way, the upper, lower, left and right sides of the center of gravity of both sides of the workpiece are locked by the clamping members 12 and locking members 11 on the clamping seats 10 on both sides, making the workpiece more stable and not easy to fall during the flipping process.

[0032] Specifically, since the two sides of the workpiece (i.e., the excavator walking frame) in this embodiment are arched, that is, the two sides are concave inward, when the two locking members 11 on the clamping seat 10 move away from each other until they respectively abut the workpiece, the left and right displacement of the workpiece can be limited, and then the two clamping members 12 are approached to each other until they respectively abut the upper and lower ends of the workpiece, so that a single clamping seat 10 can lock the upper, lower, left, and right directions of the center of gravity position of one side of the workpiece at the same time. In this way, when the clamping seats 10 at the center of gravity positions on both sides of the workpiece operate at the same time, the upper, lower, left, and right directions of the center of gravity positions on both sides of the workpiece are locked at the same time under the action of the clamping members 12 and the locking members 11 on the two clamping seats 10, ensuring that the workpiece is more stable during flipping and reducing the risk of the workpiece falling during flipping.

[0033] It should be noted that in this embodiment, the locking member 11 and the clamping member 12 can be respectively configured as a block-shaped or plate-shaped structure, so that the contact area with the workpiece is larger and the workpiece is locked more stably.

[0034] In addition, the first drive mechanism 20 and the second drive mechanism 30 can adopt hydraulic drive parts, drive cylinders or drive motors, etc.; during assembly, the drive rod or drive shaft of the first drive part is connected to the clamping part 12 and the locking part 11 respectively, or connected through a transmission part, and then the clamping part 12 and the locking part 11 are driven to move linearly through the transmission part (such as a screw, gear, etc.).

[0035] Furthermore, two mounting frames 13 are provided on the clamping seat 10, and the two mounting frames 13 extend along the second direction and can approach or move away from each other along the first direction. The two locking members 11 are respectively installed on the inner sides of the two mounting frames 13, and the second driving mechanism 30 is connected to the two mounting frames 13 to drive the two mounting frames 13 to approach or move away from each other along the first direction; the two clamping members 12 are arranged opposite to each other along the second direction and are installed on the outside of one of the mounting frames 13. The first driving mechanism 20 is connected to the two clamping members 12 and is used to drive the two clamping members 12 to approach or move away from each other along the second direction.

[0036] Specifically, during assembly, two mounting brackets 13 are provided on the clamping seat 10. The two mounting brackets 13 are arranged along a first direction and can approach or move away from each other in the first direction. Then, two locking members 11 are installed on the inner sides of the two mounting brackets 13 and protrude from the edges of the mounting brackets 13, so that when the two mounting brackets 13 approach or move away from each other, they can drive the two locking members 11 to approach or move away from each other, so that they can limit the left and right displacement of the workpiece.

[0037] In addition, a pair of clamping members 12 are installed on the outside of one of the mounting frames 13. Since the mounting frame 13 extends along the second direction, the clamping members 12 have space to move back and forth along the extension direction of the mounting frame 13 (i.e., the second direction) after installation. After the first driving mechanism 20 is installed at the top end of the mounting frame 13 and connected to the clamping members 12, the clamping members 12 can move back and forth along the extension direction of the mounting frame 13.

[0038] At the same time, the two locking members 11 can be arranged in the middle position of the mounting frame 13, so that they are located in the middle of the two clamping members 12. In this way, the locking members 11 and the clamping members 12 can be installed at the same time through the two mounting frames 13 without setting up redundant structures, so that the structural volume of the clamping seat 10 is relatively reduced, which is convenient for equipment maintenance and inspection.

[0039] Furthermore, the first drive mechanism 20 includes a first drive motor 21 and a first transmission member, and the first transmission member includes a first lead screw 22 and a first nut 23. During assembly, the first lead screw 22 is extended along the second direction and rotatably installed on the outside of the mounting frame 13, and opposite threads are set at the two sections of the first lead screw 22. The two first nuts 23 are respectively sleeved on the two sections of the first lead screw 22 and threadedly engaged with them, so that the two first nuts 23 are driven by the rotation of the first lead screw 22 to make linear motion in the extension direction of the first lead screw 22 (that is, the second direction). The two first nuts 23 are respectively connected to the two clamping members 12, so that the two clamping members 12 can also make linear motion in the second direction. Specifically, the first drive motor 21 is connected to the first lead screw 22 to drive the first lead screw 22 to rotate.

[0040] Since the two sections of the thread are opposite, that is, two sections of threads with different rotation directions are made on the first screw 22, one section is a right-hand thread and the other section is a left-hand thread. This design enables the first screw 22 to simultaneously drive the two first nuts 23 to move in opposite directions when rotating, thereby driving the two clamping members 12 to move closer to or away from each other to lock or loosen the workpiece.

[0041] It should be noted that, since the walking frame of an excavator is usually large in size and heavy in weight, if the clamping part 12 is driven to move by hydraulic drive or driving cylinder, the overall design will be more complicated, and the hydraulic drive or driving cylinder may lose pressure, resulting in cylinder explosion or pipe explosion. Therefore, in this embodiment, a drive motor, a screw and a nut are used for transmission, which is simple to assemble. Moreover, since the screw and nut transmission is self-locking, once the transmission stops, no measures need to be taken to fix it, thereby avoiding the situation where loosening due to external force affects the transmission efficiency, reducing the risk of workpiece falling, and the entire drive mechanism is more stable.

[0042] Preferably, the first screw 22 in this embodiment can be an existing bidirectional screw, and the pair of clamping members 12 can be connected to the two threaded sections of the first screw 22 respectively through two first nuts 23 with different thread directions.

[0043] More specifically, a slide groove 131 is provided on the outer side of the mounting frame 13, and first slide rails 132 are respectively provided on both sides of the slide groove 131. First sliders 133 are respectively provided at the bottom of the two clamping members 12, and the first sliders 133 are slidably installed on the first slide rails 132. In this way, the first sliders 133 can slide and cooperate with the first slide rails 132 when the two clamping members 12 approach or move away from each other, making the two clamping members 12 move closer to or away from each other smoother.

[0044] Preferably, there are four clamping members 12 in this embodiment. During assembly, a slide groove 131 is provided on the outer side of each mounting frame 13. Each pair of clamping members 12 is slidably installed on the mounting frame 13 and approaches or moves away from each other along the second direction. In this way, each clamping seat 10 has two pairs of clamping members 12 in the second direction, and each pair of clamping members 12 simultaneously clamps the upper and lower ends of the center of gravity of the workpiece, so as to limit the displacement of the upper and lower positions of the workpiece at the same time through multiple pairs of clamping members 12, so that it is locked more firmly in the second direction, further reducing the risk of the workpiece falling during the flipping process.

[0045] Furthermore, the first transmission member includes a first transmission wheel 24, a first driven wheel 25 and a first transmission belt 26. During assembly, the first transmission belt 26 is respectively wound around the first transmission wheel 24 and the first driven wheel 25 to enable the first transmission wheel 24 and the first driven wheel 25 to cooperate in transmission. The first drive motor 21 is connected to the first transmission wheel 24 and is used to drive the first transmission wheel 24 to rotate, thereby driving the first driven wheel 25 to rotate, and connecting the first driven wheel 25 to the first screw 22. In this way, the first driven wheel 25 can synchronously drive the first screw 22 to rotate when it rotates.

[0046] Since the first transmission wheel 24, the first driven wheel 25 and the first transmission belt 26 can absorb and disperse the impact and vibration generated when the first drive motor 21 starts or stops during the power transmission process, the mechanical stress on the first screw 22 and the entire transmission system is reduced, thereby extending the service life of the equipment.

[0047] In addition, since the first transmission belt 26 generally has a certain elasticity, it can alleviate the impact of load fluctuations on the system to a certain extent, making the transmission more stable and reducing the decrease in accuracy caused by vibration and impact.

[0048] Furthermore, the second driving mechanism 30 includes a second driving motor 31 and a second transmission member, and the second transmission member includes a second lead screw 32 and two second nuts 33. During assembly, the second lead screw 32 is extended along the first direction and rotatably installed on the side of the clamping base 10 close to the mounting bracket 13. Opposite threads are provided at the two ends of the second lead screw 32, and are respectively threadedly matched with the two second nuts 33, so that the two second nuts 33 are driven to make linear motion in the extension direction of the second lead screw 32 (that is, the first direction) through the rotation of the second lead screw 32. Then, after the two second nuts 33 are respectively connected to the two mounting brackets 13, the two mounting brackets 13 can approach or move away from each other when the two second nuts 33 approach or move away from each other; and the second driving motor 31 is connected to the second lead screw 32 to drive the second lead screw 32 to rotate.

[0049] Since the two sections of the thread are opposite, that is, two sections of threads with different rotation directions are made on the second screw 32, one section is a right-hand thread and the other section is a left-hand thread. This design enables the second screw 32 to simultaneously drive the two second nuts 33 to move in opposite directions when rotating, thereby driving the two clamping members 12 to move closer to or away from each other to lock or loosen the workpiece.

[0050] Preferably, the first screw 22 in this embodiment can be an existing bidirectional screw, and the pair of clamping members 12 can be connected to the two threaded sections of the first screw 22 respectively through two first nuts 23 with different thread directions.

[0051] Specifically, a current sensor can be provided on the first drive motor 21 to monitor the current change of the first drive motor 21 during operation, and a current threshold can be set in the control system of the device. This threshold is determined based on the current change of the first drive motor 21 when the clamping member 12 abuts against the workpiece. When the feedback current reaches a preset value, the action is automatically stopped, making the device more automated.

[0052] In addition, two second slide rails 14 are provided on the clamping base 10, and the two second slide rails 14 extend along the first direction. Two second sliders 134 are provided on the mounting frame 13, and the second sliders 134 are slidably installed on the second slide rails 14. In this way, the second sliders 134 can slide and cooperate with the second slide rails 14 when the two mounting frames 13 approach or move away from each other, so that the two mounting frames 13 can move closer to or away from each other more smoothly.

[0053] Furthermore, the second transmission member also includes a second transmission wheel 34, a second driven wheel 35 and a second transmission belt 36. The second transmission belt 36 is respectively wound around the second transmission wheel 34 and the second driven wheel 35 to enable the second transmission wheel 34 to cooperate with the second driven wheel 35 in transmission. The second drive motor 31 is connected to the second transmission wheel 34 and is used to drive the second transmission wheel 34 to rotate, thereby driving the second driven wheel 35 to rotate. The second driven wheel 35 is connected to the second screw 32. In this way, when the second driven wheel 35 rotates, it can drive the second screw 32 to rotate.

[0054] Specifically, since the second transmission wheel 34, the second driven wheel 35 and the second transmission belt 36 can absorb and disperse the impact and vibration generated when the first drive motor 21 starts or stops during the power transmission process, the mechanical stress on the second screw 32 and the entire transmission system is reduced, and the service life of the equipment is extended.

[0055] It should be noted that, in this embodiment, the second transmission wheel 34 and the second driven wheel 35 can be gears, and the second transmission belt 36 can be a rack belt. The three are meshed and driven to drive the second lead screw 32 to rotate, making the transmission more stable.

[0056] Furthermore, a limiting plate 15 is respectively provided at both ends of the second lead screw 32. The limiting plate 15 abuts against the mounting bracket 13 when the two locking members 11 move away from each other. When the mounting bracket 13 abuts against the limiting plate 15, the operator is prompted to move the two locking members 11 away from each other to the limit, thereby stopping the second drive motor 31 and preventing the mounting bracket 13 from falling off the second lead screw 32 during the process of moving away from each other. The structure is more practical.

[0057] Specifically, a current sensor can be provided on the second drive motor 31 to monitor the current change of the second drive motor 31 during operation, and a current threshold can be set in the control system of the device. This threshold is determined based on the change in the current of the second drive motor 31 when the mounting bracket 13 abuts against the limit plate 15. When the feedback current reaches a preset value, the action is automatically stopped, making the device more intelligent.

[0058] The technical means disclosed in the present invention are not limited to those disclosed in the above-mentioned embodiments, but also include technical solutions composed of any combination of the above-mentioned technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications are also considered to be within the scope of protection of the present invention.
