Description

Technical Field

[0001] This utility model relates to the field of quick-change technology for engineering machinery attachments, specifically a universal quick-change connection device. Background Technology

[0002] During the operation of hydraulic excavators, loaders, demolition robots and other construction machinery, it is often necessary to frequently change different functional attachments such as hydraulic hammers, buckets, hydraulic saws and hydraulic shears according to the working conditions.

[0003] Traditional bolt or manual pin connections take a long time, which seriously affects construction efficiency. Therefore, the common connection methods in the existing technology are mainly fixed rigid connection, one-way quick change device and rotary quick changer to connect different functional attachments. However, the interface positions of attachments of different brands and models are different, the interface is not universal, and additional adapter plates are required, which not only increases weight and cost but also affects construction efficiency. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a universal quick-change connection device, which solves the problem of varying interface positions of different types of attachments affecting construction efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A universal quick-change connection device includes a rotating base, a support base rotatably mounted on the rotating base, and a connecting base rotatably mounted on the rotating base;

[0007] The connector is equipped with a connection mechanism that facilitates the connection of interface attachments of different sizes.

[0008] The support base is equipped with an adjustment mechanism that facilitates the adjustment of the rotation angle;

[0009] The rotating base is equipped with a limiting mechanism that makes the connection of the rotating base more stable.

[0010] Preferably, the connecting mechanism includes a limiting groove formed on the connecting seat, an electric telescopic rod fixedly installed on the limiting groove, two sets of fixing rods fixedly installed on the limiting groove, a quick-change crescent pin slidably connected to the fixing rod fixedly installed on the movable end of the electric telescopic rod, and an insert pin fixedly installed on the quick-change crescent pin.

[0011] Preferably, the connecting mechanism further includes two sets of connecting slots formed on the connecting seat, and the connecting seat is provided with a slot.

[0012] Preferably, the adjusting mechanism includes a hydraulic cylinder fixedly installed on a support base, a fixing block fixedly installed on the movable end of the hydraulic cylinder, two sets of support frames fixedly installed on the rotating base, and the fixing block located between the two sets of support frames. Each set of support frames is provided with a sliding groove, and two sets of support columns slidably connected to the sliding groove are fixedly installed on the fixing block.

[0013] Preferably, the limiting mechanism includes a limiting post slidably mounted on one of the support posts, a spring sleeved on the limiting post, an adjusting knob fixedly mounted on the limiting post, two sets of support blocks fixedly mounted on the adjusting knob, and an insert block fixedly mounted on the adjusting knob.

[0014] Preferably, the limiting mechanism further includes two sets of grooves formed on one of the support columns and used in conjunction with the support block, wherein a plurality of slots are uniformly formed on one of the support frames and used in conjunction with the insertion block.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This utility model, through the setting of a connecting mechanism, inserts the cylindrical connecting frame on the attachment into the connecting groove, moves the attachment so that its socket and the plug are on the same plane, rotates the attachment with the cylindrical connecting frame as the center, so that the attachment is locked in the slot, and activates the electric telescopic rod to drive the plug on the quick-change crescent pin to move, so that the plug is inserted into the slot on the attachment, thereby completing the installation of the attachment, avoiding the situation where different types of attachments have different interface positions, which affects the construction efficiency.

[0017] 2. By adjusting the mechanism, the fixed block moves up and down by starting the hydraulic cylinder. The movement of the fixed block moves the support column, which moves the support column in the sliding groove on the support frame and drives the rotating seat connected to the support frame to rotate, making the connecting device more flexible in use.

[0018] 3. This utility model, through the setting of a limiting mechanism, allows the adjustment knob to be rotated to reset under the action of a spring, causing the insert block to be inserted into the corresponding slot on the support frame. The insert block is inserted into the groove, thereby limiting the support column and preventing the rotating seat from rotating, thus avoiding the situation where accidental movement of the attachment affects the construction.

[0025] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0026] Example 1

[0027] Reference Figures 1-4 This embodiment proposes a universal quick-change connection device, including a rotating seat 1, a support seat 11 rotatably mounted on the rotating seat 1, and a connecting seat 12 rotatably mounted on the rotating seat 1.

[0028] The connecting seat 12 is equipped with a connecting mechanism 2 that facilitates the connection of interface attachments of different sizes. The support seat 11 is equipped with an adjustment mechanism 3 that facilitates the adjustment of the angle of the rotating seat 1. The rotating seat 1 is equipped with a limiting mechanism 4 that makes the connection of the rotating seat 1 more stable.

[0029] The connecting mechanism 2 includes a limiting groove 21 formed on the connecting seat 12. An electric telescopic rod 22 is fixedly installed on the limiting groove 21. Two sets of fixing rods 23 are fixedly installed on the limiting groove 21. A quick-change crescent pin 24, which is slidably connected to the fixing rod 23, is fixedly installed on the movable end of the electric telescopic rod 22. Under the action of the fixing rod 23, the quick-change crescent pin 24 moves more stably. A pin 25 is fixedly installed on the quick-change crescent pin 24. The connecting mechanism 2 also includes two sets of connecting grooves 26 formed on the connecting seat 12. The connecting grooves 26 are arc-shaped to facilitate the connection of attachments. The attachment has a slot 27. When changing the attachment, the pin 25 on the quick-change crescent pin 24 is located in the limiting groove 21. The cylindrical connecting bracket on the attachment is inserted into the connecting groove 26. The attachment is moved so that its socket is on the same plane as the pin 25. The attachment is rotated around the cylindrical connecting bracket so that the attachment is locked in the slot 27. The electric telescopic rod 22 is activated to move the pin 25 on the quick-change crescent pin 24 so that the pin 25 is inserted into the slot 27 on the attachment, thereby completing the installation of the attachment. This avoids the situation where the interface positions of different models of attachments are different, which affects the construction efficiency.

[0030] Example 2

[0031] Based on Example 1, the technical solution proposed in Example 1 is used to solve the problem that the different interface positions of different types of attachments affect the construction efficiency. Since the swing mechanism is mostly a single hydraulic or mechanical form and lacks limit protection, there is a situation where the attachment moves unexpectedly and affects the construction.

[0032] Reference Figures 1-4 The adjusting mechanism 3 includes a hydraulic cylinder 31 fixedly installed on the support base 11. A fixed block 32 is fixedly installed on the movable end of the hydraulic cylinder 31. Two sets of support frames 33 are fixedly installed on the rotating base 1, and the fixed block 32 is located between the two sets of support frames 33. Each set of support frames 33 is provided with a sliding groove 34. Two sets of support columns 35 that are slidably connected to the sliding groove 34 are fixedly installed on the fixed block 32. When the hydraulic cylinder 31 is started, the fixed block 32 is moved up and down. The movement of the fixed block 32 causes the support columns 35 to move, so that the support columns 35 move in the sliding groove 34 on the support frame 33 and drive the rotating base 1 connected to the support frame 33 to rotate, making the connecting device more flexible in use.

[0033] The limiting mechanism 4 includes a limiting post 41 slidably mounted on one of the support posts 35. A spring 42 is sleeved on the limiting post 41 to allow the adjusting knob 43 to quickly return to its original position. The adjusting knob 43 is fixedly mounted on the limiting post 41. Two sets of support blocks 44 are fixedly mounted on the adjusting knob 43. Insert blocks 45 are fixedly mounted on the adjusting knob 43. The limiting mechanism 4 also includes two sets of grooves 46 formed on one of the support posts 35 and used in conjunction with the support blocks 44. Multiple sets of slots 47 that mate with the insert blocks 45 are evenly formed on one of the support posts 35. Moving the adjusting knob 43 drives the limiting post 41 and the support blocks. Move 44 so that the support block 44 moves out of the groove 46 and the insert block 45 moves out of the slot 47. Rotate the adjustment knob 43 so that the support block 44 contacts the surface of the support column 35. At this time, the insert block 45 cannot enter the slot 47, so that the angle adjustment of the rotating seat 1 is not affected. When it is necessary to limit it, rotate the adjustment knob 43 to reset it. Under the action of the spring 42, the insert block 45 is inserted into the corresponding slot 47 on the support frame 33 and the insert block 45 is inserted into the groove 46, thereby completing the limit of the support column 35, so that the rotating seat 1 cannot rotate, avoiding the situation where the attachment moves unexpectedly and affects the construction.

[0034] Working principle: Insert the cylindrical connecting bracket on the attachment into the connecting slot 26, move the attachment so that its socket and the insertion post 25 are on the same plane, rotate the attachment around the cylindrical connecting bracket as the center, so that the attachment is locked in the slot 27, start the electric telescopic rod 22 to drive the insertion post 25 on the quick-change crescent pin 24 to move, so that the insertion post 25 is inserted into the slot 27 on the attachment, thus completing the installation of the attachment. Start the hydraulic cylinder 31 to drive the fixing block 32 to move up and down, the movement of the fixing block 32 drives the support column 35 to move, so that the support column 35 moves in the sliding groove 34 on the support frame 33 and drives the rotating seat connected to the support frame 33. 1. Rotating the adjustment knob 43 moves the limiting post 41 and the support block 44, causing the support block 44 to move out of the groove 46 and the insert 45 to move out of the slot 47. Rotating the adjustment knob 43 makes the support block 44 contact the surface of the support post 35. At this time, the insert 45 cannot enter the slot 47, so that the angle adjustment of the rotating seat 1 is not affected. When it is necessary to limit it, rotating the adjustment knob 43 resets it. Under the action of the spring 42, the insert 45 is inserted into the corresponding slot 47 on the support frame 33 and the insert 45 is inserted into the groove 46, thereby completing the limit of the support post 35 and preventing the rotating seat 1 from rotating.
