Description

Technical Field

[0001] This utility model relates to the field of engineering machinery technology, and in particular to a multi-directional size adjustable hydraulic breaker connecting bracket. Background Technology

[0002] A hydraulic breaker, a common construction machinery attachment, connects to the excavator boom via a connecting pin on a mounting bracket. The hydraulic breaker mounting bracket has a connecting pin, through which the breaker connects to the excavator. To ensure effective fixation after installation, the bracket's span dimensions should match the excavator's connection end. However, due to variations in the connection end dimensions of excavators from different brands on the market, installation is often impossible due to size mismatch. Alternatively, the quick-connect couplings installed on the excavator may have size and travel requirements, further limiting the installation of the hydraulic breaker. To achieve an effective connection, it is generally necessary to replace the hydraulic breaker mounting bracket, resulting in a longer installation period and increased operating costs.

[0003] In the prior art, such as the improved structure of the fastening type breaker hammer disclosed in patent CN222500406, a fastening technology for the silent body and shell of an excavator breaker hammer is provided. The connecting pin of the connecting bracket passes through the fixed plate, which makes it impossible to adjust the inner distance and the center distance of the bucket shaft, resulting in limited product assembly adaptability. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a multi-directional adjustable breaker connecting bracket to solve the technical problems of poor adaptability, inconvenient installation and high use cost caused by the inability of existing connecting brackets to flexibly adjust the inner gap size and pin center distance size.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A multi-directional adjustable breaker connecting bracket includes a bracket base plate, two parallel side plates vertically arranged on the bracket base plate, a reinforcing plate installed on the outer side of each of the two side plates, and front pin assembly mounting holes and rear pin assembly mounting holes provided on the side plates and reinforcing plates. Front pin assembly and rear pin assembly are respectively installed in the front pin assembly mounting holes and rear pin assembly mounting holes.

[0007] The front pin assembly mounting hole is an elongated oval hole extending along the front-rear direction of the bracket, and the front pin assembly can slide along the elongated oval hole; the rear pin assembly mounting hole is a round hole, and the rear pin assembly is fixedly installed in the round hole.

[0008] The front pin assembly is provided with a front adjustment device, and the rear pin assembly is provided with a rear adjustment device. Both the front and rear adjustment devices are provided with adjustment washers, and the number of adjustment washers is adjustable.

[0009] Furthermore, the center distance dimension B between the front pin assembly and the rear pin assembly is adjusted by sliding the front pin assembly in the front pin assembly mounting hole.

[0010] Furthermore, by increasing or decreasing the number of adjusting washers in the front and rear adjustment devices, the assembly thickness on the inner side of the side plate can be changed, thereby adjusting the inner gap dimension A of the connecting bracket.

[0011] Furthermore, the front pin assembly includes a first bucket shaft, a first inner liner, and a first outer retaining ring; the first bucket shaft passes through the front pin assembly mounting hole on the side plate and the reinforcing plate; the first inner liner and the first outer retaining ring are both sleeved on the first bucket shaft, with the first inner liner located inside the side plate and the first outer retaining ring located outside the reinforcing plate.

[0012] Furthermore, the front adjustment device includes a first adjusting washer, a first pressure block, and a first connecting bolt; the first adjusting washer and the first pressure block are both sleeved on the first bucket shaft, and the first adjusting washer is located between the first inner liner and the first pressure block. The first connecting bolt passes through the first pressure block, the first adjusting washer, the first inner liner, the front pin assembly mounting hole, and the first outer retaining ring in sequence. The head of the first connecting bolt is located at the first pressure block, and the free end of the first connecting bolt is located at the first outer retaining ring and is fixed by the first nut. By tightening the first connecting bolt, the first inner liner and the first outer retaining ring clamp and fix the side plate and the reinforcing plate.

[0013] Furthermore, the contact surfaces of the first inner liner and the side plate, and the contact surfaces of the first outer retaining ring and the reinforcing plate, are all provided with a textured or patterned surface.

[0014] Furthermore, the first pressure block is provided with a stepped hole, and the head of the first connecting bolt is accommodated in the stepped hole.

[0015] Furthermore, the rear pin assembly includes a second bucket shaft, a second inner liner, and a second outer retaining ring. The second bucket shaft passes through the rear pin assembly mounting holes on the side plate and the reinforcing plate. The second inner liner and the second outer retaining ring are both fitted onto the second bucket shaft, with the second inner liner located inside the side plate and the second outer retaining ring located outside the reinforcing plate.

[0016] Furthermore, the rear adjustment device includes a second adjusting washer, a second pressure block, and a second connecting bolt; the second adjusting washer and the second pressure block are both sleeved on the second bucket shaft, and the second adjusting washer is located between the second inner liner and the second pressure block. The second connecting bolt passes through the second pressure block, the second adjusting washer, and the second inner liner in sequence. The head of the second connecting bolt is located at the second pressure block, and the free end of the second connecting bolt is screwed into the threaded holes provided in the side plate and the reinforcing plate. The rear pin assembly is fixed to the rear pin assembly mounting hole by tightening the second connecting bolt.

[0017] Furthermore, the contact surfaces of the second inner liner and the side plate, and the contact surfaces of the second outer retaining ring and the reinforcing plate, are all provided with a textured or patterned surface.

[0018] Furthermore, the second pressure block is provided with a stepped hole, and the head of the second connecting bolt is accommodated in the stepped hole.

[0019] Furthermore, a first outer retaining ring is provided at the end of the first bucket shaft, and the first outer retaining ring is fixedly connected to the end of the first bucket shaft by anti-movement bolts and nuts.

[0020] Furthermore, a second outer retaining ring is provided at the end of the second bucket shaft, and the second outer retaining ring is fixedly connected to the end of the second bucket shaft by anti-movement bolts and nuts.

[0021] Furthermore, it also includes an inner stiffening plate, located between the two side plates, with both ends fixedly connected to the two side plates respectively, and the bottom fixedly connected to the support base plate.

[0022] Furthermore, it also includes multiple external stiffening plates located outside the two side plates, with one side fixedly connected to the side plate and the bottom fixedly connected to the support base plate.

[0023] Beneficial Effects: This utility model allows for simultaneous adjustment of dimensions in two directions by adjusting the inner gap size and the pin center distance. The inner bushing at the front pin position is bolted to the bracket side plate, while the inner bushing at the rear pin position is bolted to the outer retaining ring, clamping the inner and outer washers to the bracket side plate. The inner gap size is changed by increasing or decreasing the number of adjusting shims between the inner bushing and the side plate; that is, when a larger gap size is needed, the shims on both sides can be reduced simultaneously, and when a smaller gap size is needed, the same number of shims can be added on both sides. Furthermore, the bracket ear plate hole at the rear pin position is an oblong hole, allowing the pin to slide back and forth within the oblong hole to adjust the distance between the front and rear pins. After adjusting the distance, the bolts on the inner bushing and outer retaining ring are tightened to fix the pin position. Through these two-way dimensional adjustments, the hydraulic breaker bracket can be quickly and effectively matched to different models of excavators on the market. Attached Figure Description

Detailed Implementation

[0031] The invention will now be further explained with reference to the accompanying drawings.

[0032] The core of this utility model lies in providing a simple and convenient bidirectional adjustable connecting bracket. Through its unique mechanical structure, it achieves stepless or incremental adjustment of the dimensions in two independent directions: the inner gap and the center distance, thereby overcoming the problem of limited adaptability of existing connecting brackets.

[0040] This utility model discloses a multi-directional size-adjustable hydraulic breaker connection bracket, comprising a structural support part and a size-adjustable part, as detailed below:

[0041] Structural support components:

[0042] The system comprises a base plate 1, two side plates 2, two reinforcing plates 3, an inner stiffening plate 4, and multiple outer stiffening plates 5. The base plate 1 serves as the installation foundation, directly or indirectly supporting the breaker body. The two side plates 2 are fixed vertically and parallel to each other on the base plate 1, forming the main frame connecting the support; their inner space determines the inner span dimension A. The two reinforcing plates 3 are fixed to the outer surfaces of the two side plates 2, primarily enhancing the local strength and rigidity of the side plates 2 at the pin holes, preventing deformation of the holes over long-term use. The inner stiffening plate 4 is located between the two side plates 2, with both ends fixedly connected to the two side plates 2 and the bottom fixedly connected to the base plate 1, connecting the two side plates, preventing relative deformation, and improving overall torsional rigidity. Multiple outer stiffening plates 5 are located on the outer sides of the two side plates 2, with one side fixedly connected to the side plate 2 and the bottom fixedly connected to the base plate 1, further strengthening the connection between the side plates 2 and the base plate 1, effectively distributing the working load.

[0043] The size adjustment section, including the adjustment of the inner gap dimension A and the adjustment of the pin center distance dimension B, is the key to realizing the core innovative function of this utility model. Its ingenious design lies in decoupling the two functions of "inner gap dimension A adjustment" and "center distance B adjustment" and realizing them through different mechanical principles, so that they do not interfere with each other.

[0044] The side plate 2 and the reinforcing plate 3 are provided with a front pin assembly mounting hole 201 and a rear pin assembly mounting hole 202, and a front pin assembly 6 and a rear pin assembly 8 are respectively installed in the front pin assembly mounting hole 201 and the rear pin assembly mounting hole 202.

[0045] The front pin assembly mounting hole 201 is an elongated oval hole extending along the front-rear direction of the bracket, allowing the front pin assembly 6 to slide along this hole. When adjusting the center distance B, first loosen the first connecting bolt 66, allowing the entire front pin assembly 6 to slide back and forth along the elongated hole. After adjusting to the desired position, retighten the first connecting bolt 66 to secure it. The rear mounting hole 202 is a round hole, and the position of the rear pin assembly 8 is fixed. This design concentrates the center distance B adjustment function in the front pin part, simplifying the structure and adjustment operation.

[0046] The front pin assembly 6 is provided with a front adjustment device 7, and the rear pin assembly 8 is provided with a rear adjustment device 9.

[0047] The front pin assembly 6 includes a first bucket shaft 61, a first inner liner 63, and a first outer retaining ring 62; the first bucket shaft 61 passes through the front pin assembly mounting hole 201 on the side plate 2 and the reinforcing plate 3; the first inner liner 63 and the first outer retaining ring 62 are both sleeved on the first bucket shaft 61, and the first inner liner 63 is located inside the side plate 2, and the first outer retaining ring 62 is located outside the reinforcing plate 3.

[0048] The front adjustment device 7 includes a first adjusting washer 64, a first pressure block 65, and a first connecting bolt 66. The first adjusting washer 64 and the first pressure block 65 are both sleeved on the first bucket shaft 61, and the first adjusting washer 64 is located between the first inner liner 63 and the first pressure block 65. The first connecting bolt 66 passes through the first pressure block 65, the first adjusting washer 64, the first inner liner 63, the front pin assembly mounting hole 201, and the first outer retaining ring 62 in sequence. The head of the first connecting bolt 66 is located at the first pressure block 65, and the free end of the first connecting bolt 66 is located at the first outer retaining ring 62 and is fixed by the first nut 67. By tightening the first connecting bolt 66, the first inner liner 63 and the first outer retaining ring 62 clamp and fix the side plate 2 and the reinforcing plate 3.

[0049] The rear pin assembly 8 includes a second bucket shaft 81, a second inner liner 83, and a second outer retaining ring 82. The second bucket shaft 81 passes through the rear pin assembly mounting hole 202 on the side plate 2 and the reinforcing plate 3. The second inner liner 83 and the second outer retaining ring 82 are both sleeved on the second bucket shaft 81, with the second inner liner 83 located inside the side plate 2 and the second outer retaining ring 82 located outside the reinforcing plate 3.

[0050] The rear adjustment device 9 includes a second adjusting washer 84, a second pressure block 85, and a second connecting bolt 86. The second adjusting washer 84 and the second pressure block 85 are both sleeved on the second bucket shaft 81, and the second adjusting washer 84 is located between the second inner liner 83 and the second pressure block 85. The second connecting bolt 86 passes through the second pressure block 85, the second adjusting washer 84, and the second inner liner 83 in sequence. The head of the second connecting bolt 86 is located at the second pressure block 85. The free end of the second connecting bolt 86 is screwed into the threaded holes provided in the side plate 2 and the reinforcing plate 3. The rear pin assembly 8 is fixed to the rear pin assembly mounting hole 202 by tightening the second connecting bolt 86.

[0051] By increasing or decreasing the number of the first adjusting shims 64, the inner assembly thickness can be changed, thereby precisely adjusting the inner pitch dimension A on one side. The adjustment principle of the rear pin assembly 8 is similar, achieved by increasing or decreasing the number of the second adjusting shims 84. This means that by symmetrically increasing or decreasing the total thickness of the adjusting shims on both sides, the overall inner pitch A of the bracket can be continuously changed to accommodate different excavator connecting plate thicknesses.

[0052] The contact surfaces of the first inner liner 63 and the side plate 2, and the contact surfaces of the first outer retaining ring 62 and the reinforcing plate 3, are all provided with a textured or patterned surface 301. The contact surfaces of the second inner liner 83 and the side plate 2, and the contact surfaces of the second outer retaining ring 82 and the reinforcing plate 3, are also provided with a textured or patterned surface 301. The design of the textured or patterned surface 301 significantly increases the static friction of the contact surfaces, generating strong anti-slip resistance under bolt preload, ensuring that the pin assembly will not accidentally shift under vibration conditions, and guaranteeing dimensional stability after adjustment.

[0053] The first pressure block 65 has a stepped hole, into which the head of the first connecting bolt 66 is accommodated. The second pressure block 85 has a stepped hole, into which the head of the second connecting bolt 86 is accommodated. The stepped hole design allows the heads of the first connecting bolt 66 and the second connecting bolt 86 to be recessed into the first pressure block 65 and the second pressure block 85, avoiding interference that might be caused by the bolt heads protruding from the surface of the pressure blocks, making the structure more compact and safer.

[0054] A first outer retaining ring 68 is provided at the end of the first bucket shaft 61, and the first outer retaining ring 68 is fixedly connected to the end of the first bucket shaft 61 by an anti-movement bolt 401 and a nut 402. A second outer retaining ring 87 is provided at the end of the second bucket shaft 81, and the second outer retaining ring 87 is fixedly connected to the end of the second bucket shaft 81 by an anti-movement bolt 401 and a nut 402. The cooperation of the outer retaining rings with the anti-movement bolts 401 and nut 402 constitutes a reliable axial locking mechanism, effectively preventing axial movement of the first bucket shaft 61 and the second bucket shaft 81 under long-term impact loads, thus improving the safety and reliability of use.

[0055] The specific adjustment operation process of this utility model is intuitive and simple, requiring no special tools, as described below:

[0056] Measurement and Preparation: First, measure the inner clearance dimension A and center distance dimension B of the target excavator's connecting end. Prepare standard adjusting washers of the appropriate specifications and quantity.

[0057] Coarsely adjust the center distance B: Use a wrench to loosen the first connecting bolt 66 of the front pin assembly 6 appropriately (no need to completely disassemble), so that the entire front pin assembly 6 can slide back and forth along the front pin assembly mounting hole 201. Slide it initially to near the measured B dimension scale.

[0058] Fine-tuning and fixing the inner clearance A: Based on the measured dimension A, calculate the required total thickness of the washers, and add or remove the corresponding thickness of the first adjusting washer 64 and the second adjusting washer 84 on the inner side plate 2 of the front and rear pin assemblies. After completion, manually pre-tighten all bolts to ensure that all parts are in place.

[0059] Final tightening and anti-loosening: Use a torque wrench to thoroughly tighten the first connecting bolt 66 and the second connecting bolt 86 to the specified tightening torque. At this point, thanks to the interlocking effect of the textured surface, the connection point has extremely high anti-loosening capability. Finally, tighten the anti-movement bolt 401.

[0060] Installation and verification: Connect the adjusted bracket to the excavator via the first bucket shaft 61 and the second bucket shaft 81. After confirming that there is no interference and the connection is secure, it can be put into use.

[0061] This invention achieves rapid and precise fitting of the connecting bracket through the aforementioned simple mechanical adjustment. This not only significantly improves installation efficiency and reduces users' spare parts inventory and maintenance costs, but its purely mechanical adjustment mechanism is also robust, durable, and maintenance-free, making it ideal for the harsh working conditions of construction machinery. It effectively solves the core problems of inconvenient installation and poor adaptability in existing technologies.

[0062] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
