Abstract
Description
Technical Field
[0001] This utility model relates to an excavator, and more specifically, to a vehicle swing frame. Background Technology
[0002] An excavator, also known as a digging machine or a soil excavator, is an earthmoving machine that uses a bucket to dig materials above or below the machine's bearing surface and load them into transport vehicles or unload them into a stockpile.
[0003] Excavators primarily excavate soil, coal, silt, and pre-loosened soil and rock. In recent years, the development of construction machinery has been relatively rapid, and excavators have become one of the most important pieces of machinery in engineering construction.
[0004] A bucket refers to the bucket installed on an excavator, also called a digging bucket. According to the working method, it is divided into backhoe buckets and front shovel buckets, with backhoe buckets being the most commonly used.
[0005] However, the buckets of existing excavators are not easy to adjust in terms of angle during installation and use. The angle of the excavator needs to be fully adjusted before the bucket can dig at different angles. Furthermore, the installation and disassembly of the buckets are relatively troublesome and inconvenient. Utility Model Content
[0006] One objective of this invention is to provide a new technical solution for a vehicle swing frame.
[0007] According to a first aspect of the present invention, a vehicle swing frame is provided, comprising a first connector, a second connector, and a swing arm, wherein the first connector and the second connector are engagedly connected, and the swing arm extends through the interior of the first connector and the second connector;
[0008] The first connector is fixed with a limiting rod and a limiting block on both sides respectively, and the second connector has a snap-fit groove on both sides at one end, with the limiting rod and the limiting block movably located inside the snap-fit groove;
[0009] The front end of the swing arm is connected to a swing hydraulic cylinder, and the two ends of the swing hydraulic cylinder are respectively connected to a first swing plate and a second swing plate.
[0010] Preferably, a first pin hole and a second pin hole are respectively provided on the upper and lower sides of one end of the first connector. The first pin hole is used for the first connector to be movably connected to the robotic arm, and the second pin hole is used for the first connector to be movably connected to the swing arm.
[0011] Preferably, the end face of the first connector has a first through hole, the end face of the second connector has a second through hole, and the swing arm passes through the first through hole and the second through hole in sequence.
[0012] Preferably, the end of the limiting rod is integrally formed with an anti-detachment plate, the two sides of the limiting block are integrally formed with sliders, the bottom of the snap-fit groove is provided with sliding grooves, and the sliders are movably located inside the sliding grooves.
[0013] Preferably, the end of the second connecting member is fixedly provided with a first connecting plate, the end of the swing arm member is fixedly provided with a second connecting plate, the second connecting plate is disposed between the first connecting plates, and the swing hydraulic cylinder is installed between the upper and lower second connecting plates.
[0014] Preferably, both the first connecting plate and the second connecting plate are provided with a first threaded hole and a second threaded hole, the first threaded hole and the second threaded hole are correspondingly provided, and a fixing bolt is threadedly connected in both the first threaded hole and the second threaded hole.
[0015] Preferably, the middle part of the swing arm is provided with a third pin hole, which is corresponding to the second pin hole, and the upper end of the swing arm is provided with a long pin hole for connecting the hydraulic cylinder telescopic rod.
[0016] According to one embodiment of this disclosure, the components are connected by a first connector, a second connector, and a swing arm. The first connector and the second connector are engaged by a limiting rod and a limiting block to maintain the accuracy of the connection. The swing arm extends through the components to maintain the integrity of the first connector and the second connector.
[0017] The swing arm is connected to the telescopic rod of the hydraulic cylinder through a long pin hole. The long pin hole is designed to facilitate slow pulling and pushing when the telescopic rod of the hydraulic cylinder is connected, preventing sudden pulling and pushing from causing the bucket to shake. The first connecting piece is connected to the excavator's mechanical arm through the first pin hole, and the second pin hole is connected to the swing arm to maintain the stability of the bucket.
[0018] The swing arm is inserted inside the first and second connecting parts. While maintaining the stable connection between the first and second connecting parts, it is also convenient to install and connect the end of the swing arm. The swing hydraulic cylinder at the end of the swing arm can adjust the angle of the first and second swing plates. The first and second swing plates are used to connect the bucket, which facilitates the adjustment of the bucket angle and enables multi-angle digging operations.
