Sendo os principais componentes de suporte de carga das m\u00e1quinas de constru\u00e7\u00e3o, a manuten\u00e7\u00e3o das pe\u00e7as do chassi da escavadeira est\u00e1 diretamente relacionada \u00e0 vida \u00fatil do equipamento e \u00e0 seguran\u00e7a operacional. Como profissional fabricante de pe\u00e7as de material rodante para escavadeira<\/a>, O GFM, combinado com 15 anos de experi\u00eancia no setor, fornecer\u00e1 uma interpreta\u00e7\u00e3o detalhada do ciclo de manuten\u00e7\u00e3o do sistema de chassi e especifica\u00e7\u00f5es operacionais para ajudar os usu\u00e1rios a estabelecer um sistema de manuten\u00e7\u00e3o cient\u00edfica.<\/p>

Manuten\u00e7\u00e3o e Inspe\u00e7\u00e3o Di\u00e1rias<\/h2>

Inspe\u00e7\u00e3o b\u00e1sica do sistema de trilhos<\/h3>
  • Verifica\u00e7\u00e3o de tens\u00e3o: <\/strong>Use uma r\u00e9gua para medir a inclina\u00e7\u00e3o dos trilhos. Se a folga for muito grande, o trilho pode descarrilar, e se for muito apertado, o desgaste ser\u00e1 acelerado.<\/li>\n\n
  • Remo\u00e7\u00e3o de mat\u00e9ria estranha: <\/strong>Remova objetos incrustados, como pedras e fragmentos de metal, para evitar estresse anormal nos elos da corrente<\/li>\n\n
  • Triagem visual de fissuras: <\/strong>Concentre-se em verificar se h\u00e1 rachaduras ou deforma\u00e7\u00f5es nos elos da corrente e nas soldas da placa da esteira<\/li><\/ul>

    Monitoramento do status da roda dentada e do rolo<\/h3>
    • Teste de rota\u00e7\u00e3o:<\/strong> Gire manualmente cada corpo da roda para verificar se a resist\u00eancia \u00e9 uniforme (bloqueio anormal indica danos no rolamento)<\/li>\n\n
    • Diagn\u00f3stico de vazamento de \u00f3leo: <\/strong>Verifique se h\u00e1 infiltra\u00e7\u00e3o de graxa ou ac\u00famulo de polui\u00e7\u00e3o na veda\u00e7\u00e3o do corpo da roda<\/li>\n\n
    • M\u00e9todo de marca\u00e7\u00e3o de desgaste:<\/strong> Use giz para marcar a linha de refer\u00eancia no aro da roda e compare o deslocamento no dia seguinte para determinar o progresso do desgaste<\/li><\/ul>

      Pontos principais para manuten\u00e7\u00e3o da roda guia e da engrenagem motriz<\/h3>
      • Verifica\u00e7\u00e3o do Engate do Bloco Dent\u00e1rio: Certifique-se de que o dente de acionamento e a luva do pino da esteira da corrente estejam totalmente encaixados. Se o desgaste de um dente exceder 5 mm, ele precisar\u00e1 ser substitu\u00eddo imediatamente.<\/li>\n\n
      • Enchimento de graxa: reabaste\u00e7a com graxa \u00e0 base de l\u00edtio atrav\u00e9s do bico de graxa (selecione NLGI Grau 2 para temperatura > -20 \u2103)<\/li><\/ul>

        Lista de verifica\u00e7\u00e3o pr\u00e9-operat\u00f3ria<\/h3>
        • Detec\u00e7\u00e3o de tens\u00e3o da via:<\/strong> Use uma r\u00e9gua para medir a inclina\u00e7\u00e3o da pista (valor recomendado 30-50 mm) e ajuste a tempo se o aperto for anormal<\/li>\n\n
        • Status da roda dentada\/rolo:<\/strong> Verifique visualmente se h\u00e1 vazamento de \u00f3leo, ru\u00eddo anormal e se a temperatura est\u00e1 anormal (padr\u00e3o \u226465\u2103)<\/li>\n\n
        • Verifica\u00e7\u00e3o do aperto dos parafusos:<\/strong> Concentre-se na verifica\u00e7\u00e3o dos parafusos de montagem da roda guia e da roda motriz (consulte o manual do equipamento para obter o valor do torque, geralmente os parafusos M24 precisam atingir 450 N\u00b7m)<\/li>\n\n
        • Limpeza de mat\u00e9ria estranha:<\/strong> Remova pedras e fragmentos de metal entre as placas da pista para evitar que a concentra\u00e7\u00e3o de tens\u00e3o danifique a luva do pino<\/li><\/ul>

          Pontos de Monitoramento de Opera\u00e7\u00e3o<\/h3>
          • Verifique se a pista \u00e9 desviada a cada 2 horas (desvio permitido \u22645%)<\/li>\n\n
          • Preste aten\u00e7\u00e3o \u00e0s fontes de vibra\u00e7\u00e3o anormais, especialmente ru\u00eddo anormal do chassi ao girar<\/li>\n\n
          • Monitore a temperatura do motor hidr\u00e1ulico (faixa normal de 40-80 \u2103)<\/li><\/ul>

            Processo de cuidados p\u00f3s-operat\u00f3rios<\/h3>
            • Limpe o chassi com uma pistola de \u00e1gua de alta press\u00e3o (press\u00e3o recomendada de 8-12 MPa, \u00e2ngulo de 45\u00b0)<\/li>\n\n
            • Verifique a marca de desgaste da sapata da esteira (a GFM recomenda a substitui\u00e7\u00e3o da sapata da esteira se o desgaste exceder 10 mm)<\/li>\n\n
            • Reposi\u00e7\u00e3o de graxa: adicione graxa \u00e0 base de l\u00edtio em cada ponto de lubrifica\u00e7\u00e3o a cada 8 horas<\/li><\/ul>
