Abstract
Description
Technical Field
[0001] This utility model relates to the field of excavator technology, specifically to an anti-slamming device for excavator breakers. Background Technology
[0002] Excavator breakers, as a common engineering machinery accessory, are widely used in mining, building demolition, road repair and other operations. Their working principle is to drive the piston through a hydraulic system, so that the hammer head generates high-frequency impact, thereby breaking hard objects such as rocks and concrete.
[0003] In actual operation, due to the complex and ever-changing working environment, hydraulic breakers face many risks. When demolishing old buildings, the instability of the building structure may cause the hydraulic breaker to be suddenly subjected to a large external impact during operation, causing the connection parts to loosen. In mining, the uneven hardness of the rock may cause the hydraulic breaker to generate violent vibrations when hitting hard rock. Long-term vibration can also easily cause wear and tear on the parts, which in turn affects the stability of the connection between the hydraulic breaker and the excavator. When the connection between the hydraulic breaker and the excavator is problematic, there is a risk of it falling off. Once the hydraulic breaker falls off, it will not only cause serious damage to the breaker itself and incur high repair costs, but it may also pose a great threat to the surrounding construction personnel and equipment, causing serious safety accidents.
[0004] Currently, some excavator breakers on the market use simple locking structures to prevent them from falling off, such as the common pin-type locking device. However, when faced with complex impacts and vibrations, the pin is prone to deformation or loosening due to force, and cannot reliably play the role of preventing falling off. Utility Model Content

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] Example:
[0027] Please see Figure 1-4The present invention provides the following technical solution: a device for preventing the slamming of an excavator breaker hammer, comprising a slamming mechanism 1, a mounting frame 2 and a protective plate 3, wherein the mounting frame 2 is installed at the bottom of the slamming mechanism 1 and the protective plate 3 is installed on the outside of the mounting frame 2.
[0028] The anti-collision mechanism 1 includes a fixed frame 101, lifting lugs 102, mounting block 103, fixing bolt 104, lifting frame 105, lifting block 106, fastening bolt 107, and buffer spring rod 108. Two lifting lugs 102 are fixedly connected to the top of the fixed frame 101. The mounting block 103 is installed at the bottom of the fixed frame 101. The fixing bolt 104 passes through the fixed frame 101 and is screwed to the mounting block 103. The fixing bolt 104 is fixedly connected to the bottom of the lifting frame 105. The lifting block 106 is installed on the inner side of the lifting frame 105. The fastening bolt 107 is located on the outer side of the lifting frame 105 and is screwed to the lifting block 106. The bottom of the buffer spring rod 108 is fixedly connected to the bottom of the lifting block 106, and the top of the buffer spring rod 108 is connected to the mounting block 103. The bottom fixed connection is enhanced by the anti-slamming mechanism 1, which strengthens the connection between the breaker and the excavator, greatly reducing the risk of the breaker falling due to external impact or vibration, and improving construction safety. The fixed frame 101 is equipped with reinforcing bolts on both sides to increase the connection between the mounting block 103 and the fixed frame 101 and ensure the stability of the mechanism. There are three sets of buffer spring rods 108, which are evenly distributed on the lifting block 106 to ensure the buffering effect between the lifting block 106 and the buffer spring rods 108. The lifting frame 105 is equipped with a sliding groove inside, and the size of the sliding groove is the same as that of the sliding block 111 to ensure the smooth lifting of the lifting block 106. The inner side of the fastening bolt 107 is equipped with a fastening plate to ensure that the fastening bolt 107 is firmly fixed.
[0029] The lifting block 106 includes a mounting rod 110, a sliding block 111, and a fixing plate 112. The sliding block 111 is fixedly connected to both ends of the mounting rod 110. The sliding block 111 is fixedly connected to the inner side of the mounting rod 112. The bottom of the sliding block 111 is fixedly connected to the top of the mounting frame 2. The sliding block 111 is slidably connected to the inside of the lifting frame 105, so that the lifting frame 105 can cooperate with the buffer spring rod 108 to facilitate buffering and increase the buffering effect. The connection method of the four sliding blocks 111 can ensure the fixing effect. The fixing frame 101 and the lifting block 106 adopt an inverted concave design, which makes the connection of the anti-collision mechanism 1 strong.
[0030] The protective plate 3 includes a connecting rod 301 and a plate body 302. The connecting rod 301 is fixedly connected to both sides of the mounting frame 2, and the plate body 302 is fixedly connected to the other end of the connecting rod 301. The plate body 302 protects the exterior of the anti-collision mechanism 1, reducing the entry of particles and gravel into the interior of the anti-collision mechanism 1 and improving the reliability of the device. The plate body 302 adopts a square design to protect the lower part of the fixing frame 101 and the upper part of the mounting frame 2, preventing the lifting frame 105 and the buffer spring rod 108 from being exposed, thus ensuring the protective effect. The plate body 302 is made of engineering plastic, which has a certain rigidity and disassembly, making it easy to replace and reduce costs.
[0031] When the excavator breaker is in operation, if the breaker is impacted or vibrated, the impact force is transmitted to the anti-fall mechanism 1. The lifting block 106 drives the buffer spring rod 108 to move upward. The buffer spring rod 108 is compressed and absorbs part of the impact force. The lifting block 106 slides upward within the lifting frame 105 to play a stabilizing role. The protective plate 3 prevents debris from entering the connection part, and the shock-absorbing pad reduces the impact of the breaker's vibration on the device, thereby ensuring the stable operation of the entire device and effectively preventing the breaker from falling.
[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
