Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of mud scrapers, in particular to a quick-disassembly and assembly transition connection structure of a mud scraper oil cylinder. Background Art
[0002] The process of tap water purification involves multiple processing steps, and the sludge treatment of the scraper is an indispensable part of the production. Since the scraper of the water plant is in a state of 24-hour uninterrupted operation, and the scraper cylinder bears the load of downward impact and lifting during operation, and as the state of the sludge accumulation at the bottom of the pool changes, the extension rod of the connection part between the scraper cylinder and the bottom of the pool is subjected to a load force beyond the normal range, coupled with metal fatigue caused by long-term operation, it is very easy to cause permanent accumulated damage to the thread at the connection between the cylinder thread and the extension rod. When a certain number of cycles is reached, it will cause disengagement and sudden fracture. Once disengagement and fracture occur, the equipment will not be able to operate normally and needs to be shut down for repair and recovery. The piston rod of the scraper cylinder and the connecting screw are one-piece molded components. Only the piston rod unit can be processed as a whole, which will consume a longer processing cycle. During this processing period, the mud accumulated on the bottom of the pool will gradually increase over time, affecting the water quality of the sedimentation tank. After the piston rod is repaired, the scraper cylinder and pool bottom components will experience overload failures when the machine is started again due to the increase in mud accumulation. In severe cases, the pool bottom components will be damaged, causing the pool to be stopped and drained.
[0003] It can be seen that there is still room for improvement in the existing external connection structure of the scraper oil cylinder. It should be optimized to improve the stability and reliability of the oil cylinder connection structure, and facilitate maintenance after long-term use to avoid damage to the oil cylinder piston rod, thereby reducing the impact on the water discharge of the sedimentation tank. Therefore, it is necessary to propose a more reasonable technical solution to solve the technical problems existing in the existing technology. Utility Model Content
[0004] In order to at least overcome one of the defects mentioned above, the utility model proposes a transition connection structure of a scraper cylinder that can be quickly disassembled and assembled. By setting up a transition connection structure, the piston rod of the scraper cylinder can be detachably matched, thereby preventing damage to the piston rod during long-term use, thereby ensuring the stability and reliability of the scraper. When a fault occurs, the transition connection structure can be quickly replaced to shorten the maintenance cycle.
[0005] In order to achieve the above technical effects, the transition sleeve device disclosed in the utility model can adopt the following technical solutions:
[0006] A quick-disassembly and assembly transition connection structure of a scraper oil cylinder comprises a piston rod of the oil cylinder. A transition sleeve is arranged at the end of the piston rod. The transition sleeve is connected to an extension rod through a detachable structure. The extension rod is used to connect and drive a scraper assembly.
[0007] The above disclosed transition connection structure forms a detachable transition sleeve at the end of the piston rod and connects the transition sleeve to the extension rod. The piston rod connects the transition sleeve and the extension rod to drive the subsequent scraper assembly, thereby realizing the normal operation of the scraper. After long-term use, the transition sleeve structure and the extension rod can be maintained, which can avoid damage and breakage of the piston rod, thereby greatly ensuring the stability and reliability of the cylinder assembly, reducing maintenance time, and maintaining stable production.
[0008] Further, in the present invention, the detachable structure is used to connect the transition sleeve and the extension rod, which can be constructed in various forms and is not limited to a single form. Here, an optimization is made and one feasible option is proposed: the detachable structure includes a flange structure, and the flange structure includes flanges respectively arranged on the transition sleeve and the extension rod, and the flanges are connected and fastened by a plurality of detachable fasteners. When such a solution is adopted, the transition sleeve and the extension rod are respectively formed integrally with their flanges.
[0009] Furthermore, in the present invention: the fastener comprises a bolt.
[0010] Furthermore, the connection between the transition sleeve and the piston rod can adopt a variety of schemes, which are not limited to the only one. Here, an optimization is made and one feasible option is proposed: the end of the transition sleeve is connected and matched with the end of the piston rod through a stop assembly. When such a scheme is adopted, the end of the transition sleeve can be tightly abutted against the end of the piston rod.
[0011] Furthermore, the structure of the backstop assembly is not limited to a single one, and an optimization is made here and one of the feasible options is proposed: the backstop assembly includes a connecting bolt, the head of the connecting bolt is passed through the transition sleeve to the piston rod and is tightened by a thread, and the tail of the connecting bolt is located outside the transition sleeve and is provided with a plurality of backstop nuts. When such a solution is adopted, the backstop nuts cooperate with the connecting bolts to achieve the tightening of the transition sleeve and the piston rod.
[0012] Furthermore, the location of the flange is not limited to a single location, and multiple solutions can be adopted. Here, an optimization is made and one feasible option is proposed: the flange on the transition sleeve is located at the rear of the transition sleeve and maintains a set distance from the end of the transition sleeve. When such a solution is adopted, the transition sleeve and the flange are integrally formed.
[0013] Furthermore, the matching structure of the extension rod and the transition sleeve can adopt a variety of schemes, which are not limited to the only one. Here, we optimize and propose one feasible option: the front end of the extension rod corresponds to the transition sleeve, and the front end of the extension rod forms a cavity for accommodating the end of the transition sleeve and the stop assembly. When such a scheme is adopted, after the extension rod is connected to the transition sleeve, the cavity at its front end is sleeved on the transition sleeve and fits tightly with the end of the transition sleeve.
[0014] Furthermore, in order to facilitate the connection of the transition sleeve structure, the structure of the piston rod can be adjusted and is not limited to a single one. An optimization is performed here and one of the feasible options is proposed: the piston rod includes a main section and a connecting section, a shoulder is formed between the main section and the connecting section, and the transition sleeve is fixed in cooperation with the connecting section.
[0015] Compared with the prior art, some beneficial effects of the technical solution disclosed in the utility model include:
[0016] The utility model adjusts the piston rod connection structure of the oil cylinder and connects the piston rod to the scraping component of the scraper machine through the transition connection structure. During long-term operation, the damage of the piston rod structure can be avoided. Only the transition connection structure needs to be inspected and maintained, which greatly shortens the maintenance time and improves the maintenance efficiency, so that the scraper machine can maintain normal and stable operation.
