Description

Technical Field

[0001] The present invention relates to the technical field of car tippers, and more particularly to a fixing device for a rotating car coupler. Background Art

[0002] In the existing technology, vehicles that can be loaded onto the dumper are mixed with vehicles that cannot be loaded onto the dumper, which results in vehicles having to be unhooked before loading onto the dumper, significantly increasing the unloading time.

[0003] In order to reduce unloading time, rotating couplers are often used at both ends of the vehicle. Although this solves the problem of the need to remove the couplers on the mixed vehicle tipping machine, when the tipping machine flips, due to the lack of fixed coupler limits, the two rotating couplers will rotate together with the flipping vehicle, resulting in inaccurate or impossible reset of the rotating couplers after unloading. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a fixing device for a rotating coupler, which effectively limits the rotation of the rotating coupler relative to the impact seat, thereby achieving temporary fixation of the rotating coupler; it can ensure that one of the rotating couplers connected to the fixing device is fixed, ensuring that after the vehicle is reset after unloading, its rotating coupler can also be accurately reset together;

[0005] The solution adopted by the present invention to solve the technical problem is:

[0006] A fixing device for a rotating coupler is arranged between an impact seat and a hook shoulder of the rotating coupler; it includes an impact seat clamping block assembly clamped with the upper edge of the impact seat, and a coupler clamping plate assembly clamped with the impact seat clamping block assembly at one end and the hook shoulder at the other end.

[0007] In some possible implementations, the impact seat clamp assembly includes a clamping block 1 that is clamped to the upper edge of the impact seat on the side of the impact seat close to the rotating coupler, and a clamping block 2 that is connected to the end of the clamping block 1 close to the rotating coupler.

[0008] In some possible implementations, the coupler clamp assembly includes a clamping plate 1 clamped to the clamping block 2, and a clamping plate 2 connected to a side of the clamping plate 1 away from the clamping block 2 and clamped to the hook shoulder.

[0009] In some possible embodiments, the clamping block 1 has a U-shaped structure, including a mounting plate and two groups of horizontal plates mounted on the mounting plate and arranged horizontally; the mounting plate and the two groups of horizontal plates cooperate with each other to form a U-shaped slot 1 that is engaged with the upper edge of the impact seat.

[0010] In some possible embodiments, the clamp block 2 includes two groups of vertical plates 2 installed on the side of the mounting plate away from the horizontal plate and arranged parallel to each other, and a rib plate arranged between the two groups of vertical plates 2 and respectively connected to the two groups of vertical plates 2 and the mounting plate.

[0011] In some possible embodiments, the clamping plate 1 is a U-shaped structure, including a fixed plate, two groups of vertical blocks 1 installed on the side of the fixed plate close to the clamping block 2 and located on the outside of the clamping plate 2, and the two groups of vertical blocks 1 are arranged parallel to the vertical plate 2; the fixed plate and the two groups of vertical blocks 1 cooperate with each other to form a U-shaped slot 2 that is clamped with the clamping block 2.

[0015] In some possible implementations, the axes of the first U-shaped slot, the second U-shaped slot, and the third U-shaped slot are coplanar.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0030] The present invention is described in detail below.

[0031] like Figures 1-8As shown, a fixing device for a rotating coupler is arranged between the impact seat and the hook shoulder of the rotating coupler 10; it includes an impact seat clamping block assembly 1 that is clamped with the impact seat upper edge 20 at the impact seat opening, and a coupler clamping plate assembly 2 that is clamped with the impact seat clamping block assembly 1 at one end and clamped with the hook shoulder at the other end.

[0032] A U-shaped card slot 13 is provided on the side of the impact seat clamping block assembly 1 close to the impact seat; a U-shaped card slot 213 is provided on the side of the coupler clamping plate assembly 2 close to the impact seat clamping block assembly, and a U-shaped card slot 3 222 is provided on the side of the coupler clamping plate assembly 2 away from the impact seat clamping block assembly 1. The axis of the U-shaped card slot 13 is snap-fitted with the impact seat upper edge 20 of the impact seat along the X-axis direction; the axes of the U-shaped card slot 213 and the U-shaped card slot 3 222 are arranged along the Z-axis direction, wherein the U-shaped card slot 213 is snap-fitted with the impact seat clamping block assembly 1, and the U-shaped card slot 3 222 is snap-fitted with the hook shoulder of the coupler;

[0033] During installation, the impact seat clamping block assembly 1 is installed first, and the U-shaped slot 13 is engaged with the upper edge 20 of the impact seat; then the coupler clamping plate assembly 2 is installed along the Z-axis direction, and the U-shaped slot 213 is engaged with the side of the impact seat clamping block assembly 1 away from the upper edge 20 of the impact seat, and the U-shaped slot 3 222 is engaged with the hook shoulder of the rotating coupler 10; after installation, since the impact seat is fixedly connected to the vehicle body, the group of rotating couplers 10 is temporarily fixed relative to the impact seat, which limits the rotation of the group of rotating couplers 10 relative to the impact seat; thereby ensuring that after unloading is completed, the rotating coupler 10 can also be accurately reset when the vehicle is reset.

[0034] By engaging the U-shaped groove 1 with the upper edge 20 of the impact seat, the impact seat effectively limits the displacement of the impact seat clamp assembly 1 in the Z-axis direction, the displacement along the Y-axis direction toward the side close to the rotating coupler 10, and the rotation around the Y-axis and X-axis directions;

[0035] The U-shaped slot 213 is engaged with the impact seat clamp assembly 1, thereby effectively limiting the displacement of the coupler clamp assembly 2 along the X-axis direction, the displacement along the Y-axis direction toward the side close to the rotating coupler 10, and the rotation around the Y-axis direction;

[0036] The U-shaped slot 222 is engaged with the shoulder of the rotating coupler 10, thereby limiting the rotation of the rotating coupler 10 around the Y-axis direction;

[0037] Through the above arrangement, the freedom of the rotating coupler 10 and the impact seat is effectively constrained. Since the axes of the U-shaped slot 213 and the U-shaped slot 3 222 are both arranged along the Z-axis direction, the displacement of the coupler clamp assembly 2 along the Z-axis direction is released, thereby facilitating the installation and disassembly of the device.

[0038] In some possible embodiments, the impact seat clamp assembly 1 includes a clamp 11 that is clamped to the upper edge 20 of the impact seat near the rotating coupler 10, and a clamp 2 12 that is connected to the end of the clamp 11 near the rotating coupler 10.

[0039] The clamping block 11 and the clamping block 2 12 can be integrally formed by casting; wherein the U-shaped slot 13 is provided on the clamping block 11;

[0040] In some possible implementations, the coupler clamp assembly 2 includes a clamp 1 21 clamped to the clamp 2 12 , and a clamp 2 22 connected to the side of the clamp 1 21 away from the clamp 2 12 and clamped to the hook shoulder.

[0041] The first clamping plate 21 and the second clamping plate 22 are integrally formed. A second U-shaped slot 213 is provided on the side of the first clamping plate 21 close to the upper edge 20 of the impact seat, and a third U-shaped slot 222 is provided on the side of the second clamping plate 22 close to the rotating coupler 10.

[0042] In some possible implementations, in order to effectively achieve the clamping connection between the clamping block 11 and the upper edge 20 of the impact seat;

[0043] The clamping block 11 has a U-shaped structure, including a mounting plate 111 and two sets of horizontal plates 112 mounted on the mounting plate 111 and arranged horizontally; the mounting plate 111 and the two sets of horizontal plates 112 cooperate with each other to form a U-shaped slot 13 that is engaged with the upper edge 20 of the impact seat.

[0044] In some possible implementations, in order to effectively engage the clamping block 2 12 with the coupler clamp assembly 2;

[0045] The second clamping block 12 includes two sets of second vertical plates 121 installed on the side of the mounting plate 111 away from the horizontal plate 112 and arranged in parallel, and a rib plate 122 arranged between the two sets of second vertical plates 121 and connected to the two sets of second vertical plates 121 and the mounting plate 111 respectively.

[0046] The rib plate 122 is used to strengthen the overall rigidity of the clamping block 2 12 to prevent deformation during use;

[0047] In some possible implementations, in order to effectively achieve the clamping connection between the first clamping plate 21 and the second clamping block 12;

[0048] The clamping plate 1 21 has a U-shaped structure, including a fixed plate 212 and two groups of vertical blocks 1 211 installed on the fixed plate 212 close to the clamping block 2 12 and located on the outside of the clamping block 2 12. The two groups of vertical blocks 1 211 are arranged parallel to the vertical plate 2 121; the fixed plate 212 and the two groups of vertical blocks 1 211 cooperate with each other to form a U-shaped slot 2 213 that is clamped with the clamping block 2 12.

[0049] The second vertical plate 121 and the first vertical block 211 are arranged along the Z-axis direction;

[0050] The two groups of vertical blocks 1 211 are arranged on the outside of the clamping block 2 12 and are arranged parallel to the vertical plate 2 121, forming a gap between the two. A gap is formed between the vertical plate 2 121 and the U-shaped slot 2 213 on one side close to each other, and the above gap is 2-3mm; this can effectively meet the installation requirements.

[0051] In some possible implementations, in order to effectively achieve the clamping connection between the second clamping plate 22 and the hook shoulder of the rotating coupler 10;

[0052] The second clamping plate 22 includes two sets of second vertical blocks 221 mounted on the side of the fixed plate 212 away from the first vertical block 211 and arranged parallel to each other. The two sets of second vertical blocks 221 and the fixed plate 212 cooperate with each other to form a U-shaped slot 3 222 that engages with the hook shoulder. The second vertical blocks 221 are arranged along the Z-axis direction.

[0053] After installation, the hook shoulder of the rotating coupler 10 will be located in the U-shaped slot 3 222, and a gap will be formed between the outer side of the hook shoulder and the vertical block 221. A gap will be formed between the side of the hook shoulder close to the fixed plate 212 and the fixed plate 212, and the gap is 2-3 mm.

[0054] Further, such as Figure 2 、 Figure 5 As shown, the fixing plate 212 includes a plate body 1 for mounting the vertical block 1 211 , a plate body 2 connected to the side of the plate body 1 away from the vertical plate 1, and the vertical block 221 is mounted on the side of the plate body 2 away from the plate body 1.

[0055] In some possible implementations, in order to facilitate the installation and disassembly of the device and to effectively constrain the degree of freedom of the rotating coupler 10 relative to the impact seat;

[0056] The axis of the first U-shaped slot 13 is arranged along the X-axis direction, and the axes of the second U-shaped slot 213 and the third U-shaped slot 222 are both arranged along the Y-axis direction.

[0057] In some possible implementations, in order to effectively ensure installation requirements;

[0058] There is a clearance fit between the inner side of the U-shaped slot 13 and the outer side of the upper edge 20 of the impact seat, between the inner side of the U-shaped slot 213 and the outer side of the clamping block 2 12, and between the inner side of the U-shaped slot 3 222 and the outer side of the hook shoulder, and the clearance is 2-3 mm.

[0059] In some possible implementations, the axes of the first U-shaped slot 13, the second U-shaped slot 213, and the third U-shaped slot 222 are coplanar.

[0060] The present invention is not limited to the aforementioned specific embodiments, but extends to any new features or any new combination disclosed in this specification, as well as any new method or process steps or any new combination disclosed.
