Description

Technical Field

[0001] This utility model relates to the technical field of excavator bucket packing auxiliary tools, and more specifically, it relates to an excavator bucket packing fixing bracket. Background Technology

[0002] Excavator buckets are an important component of excavators. After production, they need to be secured by a fixed bracket during the packaging process to prevent collisions during transportation. However, existing excavator bucket packaging and fixing brackets have some drawbacks that affect daily use.

[0003] The primary problem is that the existing excavator bucket mounting brackets lack a stable load-bearing structure. Without a stable load-bearing structure, the brackets cannot evenly distribute the weight of the bucket, which can easily lead to localized stress concentration. When the transport vehicle is traveling on a bumpy road or braking suddenly, the weight of the bucket will be concentrated on the weak points of the bracket, which may cause the bracket to deform or break, or even cause the bucket to slip off the bracket. Once such a situation occurs, it will not only damage the bucket and the transport vehicle, but may also pose a fatal threat to other vehicles, pedestrians and surrounding facilities on the road, causing serious traffic safety accidents.

[0004] More importantly, existing excavator bucket mounting brackets lack bucket limiting devices. During transport, when encountering turns, braking, or road bumps, the bucket will tend to shift longitudinally or laterally due to inertia. Without the restraint of limiting devices, the bucket may slide, deviate, or even move along the bracket. When the displacement is too large, it may cause the bucket to collide with the bracket, generating noise and vibration, or even cause the bucket's center of gravity to deviate from the bracket's center, leading to bracket tilting or even the bucket slipping off the bracket. Excavator buckets of different models and sizes vary greatly in shape and size, and without adjustable limiting devices, the brackets cannot adapt to the fixing requirements of buckets of different specifications.

[0005] Crucially, existing excavator bucket mounting brackets lack an anti-tipping frame. During road transport, vehicle turns, rapid acceleration, or emergency braking can generate significant centrifugal or inertial forces in the bucket. Without an anti-tipping frame, the bucket, relying solely on its bottom fixing structure, cannot effectively counteract lateral forces, making it highly susceptible to tilting or even tipping over entirely. Once the bucket tipps over, it can cause damage such as crushing the transport vehicle, deforming the bucket itself, and chipping the cutting edge. In more serious cases, it can shift the vehicle's center of gravity, leading to a rollover accident. In areas with heavy traffic, such as highways, it could even collide with other vehicles, causing a chain reaction accident and posing a serious threat to drivers, passengers, and road infrastructure. Utility Model Content

[0006] In view of the problems existing in the prior art, this utility model provides an excavator bucket box fixing bracket to solve the technical problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a bucket loading and fixing bracket for excavators, comprising a support device, an anti-tipping outer frame, and a limiting device. The support device is detachably connected to the anti-tipping outer frame and the limiting device. The support device includes a support beam, a high-strength hinge, a bottom frame, a base, and a shock-absorbing rubber pad. The base is detachably connected to the bottom frame. The support beam has multiple components and is interconnected by high-strength hinges. The support beam is connected to the bottom frame by high-strength hinges. The support beam is in contact with the base and the shock-absorbing rubber pad. The limiting device includes a limiting block, limiting holes, fastening bolts, pressure blocks, and extension bolts. The support beam has multiple evenly arranged limiting holes. The limiting block is threadedly connected to the fastening bolts and extension bolts. The limiting block is movably connected to the support beam by the fastening bolts. The pressure block is movably connected to the support beam by the extension bolts. The anti-tipping outer frame is detachably connected to the base.

[0008] The present invention is further configured such that the anti-tipping outer frame includes a frame body, a connecting seat, a support rod, and a top rod. The frame body is fixedly connected to the connecting seat and the support rod respectively. Multiple support rods are provided and evenly distributed on the outside of the frame body. The top rod is detachably connected to the frame body.

[0009] The present invention is further configured such that the base is provided with a slot, which improves the convenience of transporting the entire bracket.

[0010] The present invention is further configured such that the top rod is connected to the frame by screws, and the connecting seat is connected to the base by screws, thereby improving the convenience of inspection.

[0011] The present invention is further provided with a threaded washer between the limiting block and the fastening bolt, and the threaded washer is movably connected to the limiting block and the fastening bolt respectively, thereby improving the stability of the limiting.

[0012] The present invention is further provided that a buffer pad is fixedly connected to the bottom of the support rod, which improves the stability of the support.

[0013] The present invention is further provided that the base is provided with two lifting lugs, which are respectively fixedly installed on both sides of the base, thereby improving the convenience of transporting the entire bracket.

[0014] Compared with the prior art, this utility model provides a fixing bracket for excavator buckets, which has the following advantages: 1. Through the tight cooperation between the support beam, high-strength hinge, bottom frame, base, and shock-absorbing rubber pads, a complete and stable support device is formed. The stable load-bearing structure can evenly distribute the weight of the bucket to various stress points of the support, avoiding structural deformation or fracture caused by local stress concentration. During transportation, whether the vehicle encounters a turn, sudden braking, or bumpy road, the load-bearing structure can provide stable support for the bucket, effectively suppressing the swaying and displacement of the bucket. This not only prevents the bucket from slipping off the support and avoiding threats to transport vehicles, road facilities, and surrounding personnel, but also reduces the vehicle's center of gravity shift caused by bucket swaying, reducing the probability of serious accidents such as vehicle rollover, and providing a solid safety guarantee for the entire transportation process.

[0015] 2. Through the tight cooperation between the limiting block, limiting hole, fastening bolt, pressure block and extension bolt, a complete bucket limiting device is formed. The limiting device can fix the bucket in the preset position of the support. When the transport vehicle turns, brakes suddenly or passes through bumpy roads, it can effectively counteract the inertial force generated by the bucket and prevent it from sliding laterally or moving longitudinally. This not only prevents the bucket from violently colliding with the support and the truck bed wall and reducing structural damage caused by the collision, but also prevents the support from tilting or the vehicle from becoming unbalanced due to the shift of the bucket's center of gravity. It reduces the probability of safety accidents such as rollover and falling objects during transportation from the source and provides a solid guarantee for road transport safety.

[0016] 3. Through the tight cooperation between the frame, connecting seat, support rod and top rod, a complete anti-tipping outer frame is formed. The anti-tipping outer frame can provide lateral support for the bucket and effectively resist various external impacts during transportation. When the vehicle turns and generates centrifugal force, or when emergency braking causes inertial force, or when there is up and down vibration on bumpy road, the longitudinal and transverse frames of the outer frame will form a rigid barrier to limit the displacement of the bucket and prevent it from tilting to one side or tipping over as a whole. This not only prevents the bucket from smashing through the transport car and damaging the vehicle structure, but also prevents road traffic accidents caused by the bucket falling.

[0022] Please see Figures 1-5 A bucket loading and fixing bracket for excavators includes a support device, an anti-tipping outer frame, and a limiting device. The support device is detachably connected to the anti-tipping outer frame and the limiting device. The support device includes a support beam 1, a high-strength hinge 2, a bottom frame 3, a base 4, and a shock-absorbing rubber pad 5. The base 4 is detachably connected to the bottom frame 3. The support beam 1 has multiple beams that are interconnected by the high-strength hinge 2. The support beam 1 is connected to the bottom frame 3 by the high-strength hinge 2. The support beam 1 is in contact with the base 4 and the shock-absorbing rubber pad 5. The limiting device includes a limiting block 6, limiting holes 7, fastening bolts 8, pressure blocks 9, and extension bolts 10. The support beam 1 has multiple evenly arranged limiting holes 7. The limiting block 6 is threadedly connected to the fastening bolts 8 and the extension bolts 10. The limiting block 6 is movably connected to the support beam 1 by the fastening bolts 8. The pressure block 9 is movably connected to the support beam 1 by the extension bolts 10. The anti-tipping outer frame is detachably connected to the base 4.

[0023] In a further embodiment of this application, the anti-tipping outer frame includes a frame body 11, a connecting seat 12, a support rod 13, and a top rod 14. The frame body 11 is fixedly connected to the connecting seat 12 and the support rod 13 respectively. Multiple support rods 13 are provided and evenly distributed on the outside of the frame body 11. The top rod 14 is detachably connected to the frame body 11.

[0024] In a further embodiment of this application, the base 4 is provided with a slot 15, through which the forklift forks can move the entire bracket.

[0025] In a further embodiment of this application, the top rod 14 is connected to the frame 11 by screws 16, and the connecting seat 12 is connected to the base 4 by screws 16. If it is necessary to check the bucket fixation in the middle, the screws 16 can be removed and the top rod 14 can be removed from the frame 11 to check the bucket.

[0026] In a further embodiment of this application, a threaded washer 17 is provided between the limiting block 6 and the fastening bolt 8. The threaded washer 17 is movably connected to the limiting block 6 and the fastening bolt 8 respectively, and the threaded washer 17 makes the tightening of the screw 16 more stable.

[0027] In a further embodiment of this application, a buffer pad 18 is fixedly connected to the bottom of the support rod 13 to reduce the impact force brought by the support rod 13 when providing support.

[0028] In a further embodiment of this application, the base 4 is provided with two lifting lugs 19, which are respectively fixedly installed on both sides of the base 4. After the bucket is fixed, the lifting lugs 19 can be used to lift and transport the entire frame.

[0029] In this embodiment, when the device is to be used, the bucket is placed on the shock-absorbing rubber pad 5 on the support beam 1. After selecting a suitable limiting hole 7, the limiting block 6 is fixed to the support beam 1 with fastening bolts 8, so that the two sides of the bucket are clamped and fixed. Then, the pressure block 9 is pressed on the bucket teeth and fixed to the support beam 1 with extension bolts 10 to prevent the bucket from shifting due to bumps during transportation. After the bucket is fixed, the frame 11 is fixed to the base 4 with connecting seat 12 and screws 16. The threaded washer 17 makes the tightening of the screws 16 more stable. Then, the top rod 14 is fixed to the frame 11 with screws 16 to protect the bucket from falling out of the limiting device and then falling off the base 4. The support rod 13 and the buffer pad 18 can effectively prevent the base 4 from tilting excessively during transportation, which would cause the bucket to become unstable.

[0030] More specifically, once the bucket is fixed, the entire support frame can be lifted and moved using the lifting lug 19, or the forks of a forklift can be inserted into the slot 15 for transport. When the bucket encounters bumps during transport, the impact force of the bucket falling is first absorbed by the shock-absorbing rubber pad 5 and then transferred to the support beam 1. The support beams 1 are connected to each other by high-strength hinges 2 and to the bottom frame 3 by high-strength hinges 2. The segmented load-bearing structure allows the force on the support beam 1 to be transferred between the support beam 1, the bottom frame 3 and the base 4, reducing stress concentration, making the load-bearing more even, and avoiding excessive local stress that could damage the support frame.

[0031] In summary, when using or operating the entire equipment: when placing and fixing the bucket, place the bucket on the shock-absorbing rubber pad 5 on the support beam 1, select a suitable limiting hole 7, and use the fastening bolt 8 to fix the limiting block 6 on the support beam 1, so that the two sides of the bucket are clamped and fixed. Then, press the pressure block 9 on the bucket teeth and fix the pressure block 9 on the support beam 1 with the extension bolt 10 to prevent the bucket from shifting due to bumps during transportation. After fixing the bucket, fix the frame 11 to the base 4 through the connecting seat 12 and screws 16. The threaded washer 17 makes the tightening of the screws 16 more stable. Then, fix the top rod 14 to the frame 11 with screws 16 to protect the bucket from falling out of the limiting device and then falling off the base 4. The support rod 13 and the buffer pad 18 can effectively prevent the base 4 from tilting excessively during transportation, which would cause the bucket to become unstable.

[0032] More specifically, once the bucket is fixed, the entire support frame can be lifted and moved using the lifting lug 19, or the forks of a forklift can be inserted into the slot 15 for transport. When the bucket encounters bumps during transport, the impact force of the bucket falling is first absorbed by the shock-absorbing rubber pad 5 and then transferred to the support beam 1. The support beams 1 are connected to each other by high-strength hinges 2 and to the bottom frame 3 by high-strength hinges 2. The segmented load-bearing structure allows the force on the support beam 1 to be transferred between the support beam 1, the bottom frame 3 and the base 4, reducing stress concentration, making the load-bearing more even, and avoiding excessive local stress that could damage the support frame.

[0033] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model. The scope of this utility model is defined by the appended claims and their equivalents.
