Problems solved by technology

[0002] At present, the reciprocating impact frame of the impact roadheader, impact shearer or impact excavator is directly connected with the power drive and the impact head, etc. When the impact head impacts the material, the reciprocating impact frame bears a large lateral force. The lateral force greatly damages the seal between the reciprocating impact frame and the impact power box, often causing damage to the seal. Dust, liquid, materials, etc. enter the impact power box, resulting in serious equipment failure, which greatly reduces the use efficiency of the equipment. In order to reduce the damage to the seal by the reciprocating impact frame, it is required to make the friction part between the reciprocating impact frame and the seal extremely high precision. Because the reciprocating impact frame is large in size, heavy in weight, complex in shape and requires extremely high precision, it is necessary to process the reciprocating impact frame. It is extremely difficult to process the parts of the impact frame that are prone to wear. In order to increase the structural strength of the reciprocating impact frame, the upper impact guide and the lower impact guide of the reciprocating impact frame must be fixedly connected through the guide rod connector or the upper impact guide , The lower impact guide and the connecting piece of the guide rod are integrated. In order to ensure the precise position of the upper impact guide, the lower impact guide, the impact power box

Abstract

A reciprocating-impact excavating part for use in an excavating machine and having wear-resistant guiding sleeves that are easy to process/assemble/disassemble and are fastened by elongated threaded rods. Wear-resistant guiding sleeves (4) are arranged between impact guiding members (1) and an enclosure (8) and/or arranged between the impact guiding members (1) and rolling friction bodies (7). Impact heads (9) are arranged at one ends or either ends of the impact guiding members (1). Impacting teeth (12) are arranged on impacting teeth bases (11). When guiding threaded rods (13) are separated from the impact guiding members (1), the guiding threaded rods (13) are run through guiding threaded-rod holes (15) to be mated with guiding nuts (14) to fasten the impacting teeth bases (11), the wear-resistant guiding sleeves (4), the impact guiding members (1), and a guiding rod connector (2) into a single-body reciprocating impact frame (16). Alternatively, when the guiding threaded rods (13) and the impact guiding members (1) are a single body, the guiding threaded rod (13) are mated with the guiding nuts (14) to fasten the impacting teeth bases (11), the wear-resistant guiding sleeves (4), and the guiding rod connector (2) into the single-body reciprocating impact frame (16). The wear-resistant guiding sleeves (4) are driven by the guiding rod connector (2) and supported by the rolling friction bodies (7) to make reciprocating movements, thus increasing the practicability and service life of equipment.

Description

technical field [0001] The invention belongs to the field of machinery, and is especially suitable for a excavator in the field of excavation. It uses a long screw to fasten and easy to process and disassemble a guide wear-resistant sleeve to reciprocate and impact the excavation part.
