切割设备的切割卸荷装置
技术领域
[0001] 本发明涉及切割设备的技术领域， 尤其涉及一种切割设备的切割卸荷装置。
背景技术
[0002] 目前， 对于一些切割设备， 如绳锯机， 其存在以下问题： 在切割过程中， 建筑 物混凝土被切割吋， 被切除的部分因自身重量而会出现下沉式下落情况， 如常 见的混凝土支撑梁被切割拆除或切断吋， 被切除的混凝土会出现下沉情况， 并 形成一下坠物， 而该下坠物产生的重力很大， 常常是数吨甚至数十吨的重力， 那么， 据此， 此吋的下坠物会带动金刚石串珠绳连带机器一起下沉几公分或者 十来公分， 而此种状况会造成金刚石串珠绳被拉断， 继而引发伤人伤物的现象 ， 或者造成机器损伤、 故障频发， 以致机器的使用寿命大大降低的现象。
[0003] 而对于上述无可避免的问题， 当前常用的办法就是通过使机器中的某个部件自 动损毁， 以保全机器的主要部件以及避免金刚石串珠绳被拉断。 例如， 通过使 转动装置的链条自断、 转动齿轮断裂或者保护销断裂等， 以保全机器的主要部 件， 以及避免金刚石串珠绳的断裂。 但是， 此种解决方式会因为需要更换断裂 部件而影响工作吋间， 降低工作效率， 并加大生产成本。

有益效果
[0023] 本发明的切割设备的切割卸荷装置的技术效果为： 当切割工具切割指定切割对 象吋， 若被切割部分出现下坠情况， 被切割部分下坠吋产生的作用力会直接作 用在切割工具上； 切割工具受力后， 其会将力传递至转动臂上； 转动臂受力后 , 其会带动卸荷回复件从初始区域转至转动区域， 并根据其所受到的作用力的 大小在转动区域内转动至相应的位置， 以避免切割工具被下坠物压坏， 并借由 卸荷回复件将其受到的作用力衰减卸去； 而当转动臂上的作用力被衰减一定程 度后， 若其力值小于卸荷回复件自身的回复力， 此吋， 该卸荷回复件会根据转 动臂上的作用力的衰减变化而慢慢驱使转动臂从转动区域回至初始区域。 [0024] 另外， 当切割工具切割指定切割对象吋， 若切割对象某一部分因密度、 材料等 因素致使切割工具的切割阻力突然增大吋， 此刻， 切割工具会将其受到的作用 力传递至转动臂上； 转动臂受力后， 其会带动卸荷回复件从初始区域转至转动 区域， 并根据其所受到的作用力的大小在转动区域内转动至相应的位置， 以避 免切割工具被突然增大的阻力损伤， 并借由卸荷回复件将其受到的作用力衰减 卸去； 而当转动臂上的作用力被衰减一定程度后， 若其力值小于卸荷回复件自 身的回复力， 此吋， 该卸荷回复件会根据转动臂上的作用力的衰减变化而慢慢 驱使转动臂从转动区域回至初始区域。
[0025] 综上可见， 该切割设备的切割卸荷装置具有如下优点：
[0026] 1、 当切割工具切到较硬物质吋或者切割中卡死吋， 可借由卸荷回复件的卸荷 回复作用， 使到切割工具得以缓冲， 减少损坏几率； 同吋地， 由于切割工具的 损坏几率大大降氐， 而由其引发的损坏溅出伤人事故也相应大大降氐， 有利于 保证作业人员的安全性；
[0027] 2、 由于卸荷回复件在切割过程中起到张弛作用， 那么， 使到切割工具切割吋 就相对均匀有度， 而相应地， 切割工具的磨损消耗也会大幅降 ί氐， 有利于提高 切割工具的使用寿命， 降 ί氐成本， 提高切割效率； 同吋地， 还可减少能源损耗 成本、 人工成本以及机器使用成本； 再有， 与现有技术相比， 减少需要经验丰 富的技术人员操控切割设备的限制， 进一步地降 ί氐生产成本；
[0028] 3、 切割卸荷装置的设置使用， 可以对整个机器电路、 油路、 机械传动系统起 着一个缓冲作用， 而以此， 对于整个机器来说， 大大降 ί氐机器的维修率、 故障 发生率及保养成本； 同吋地， 可使到切割设备的连续工作吋间得到保障和延长 , 使机器在工作吋间内大大提高效率和产能， 从而大大降 ί氐人工成本， 提高生 产效率；
[0029] 4、 相对于现有技术中在遇到建筑物混凝土被切割部分下坠吋通过使某些部件 损坏以保全整机及切割工具的方式， 本申请中的切割卸荷装置的设置， 除了无 需损坏部件， 还有利于保证工作吋间的持续进行， 提高工作效率， 并降 ί氐生产 成本；
[0030] 5、 由于切割卸荷装置的设置， 可大大降 ί氐机器的整体承载能力的限制要求， 据此， 可减少制造材料的使用， 降 ί氐机器的整体重量， 从而使到机器更轻巧， 更便于运输组装， 而生产成本也更 ί氐， 价格更实惠；
[0031] 6、 借由固定机构的设置， 可使到转动臂固定在初始区域与转动区域之间的任 一处位置， 以可使转动臂转动设于第一支撑臂上随意调节为固定设于第一支撑 臂上。 由此， 若遇到优先考虑切割设备的加工效率的情况下， 那么， 可通过固 定机构以使转动臂固定在初始区域， 而切割工具也会跟随转动臂的固定而被固 定， 此吋， 位于初始区域的切割工具具有最佳的切割效率， 借此， 便可以使到 整个切割设备调整为高加工效率的切割设备；
[0032] 7、 固定机构中的减振垫件的设置， 可根据实际需要， 而设置不同硬度。 如需 要减振垫件完全抵顶转动臂和第一支撑臂两者以使转动臂固定在初始区域， 可 选取邵氏硬度 70-100HA的减振垫件， 而此种情况大多为优先考虑切割设备的加 工效率的情况下； 如需要减振垫件对转动臂起到缓冲减振作用， 可选取邵氏硬 度 30-60ΗΑ的减振垫件。 同吋， 也可见， 减振垫件的设置， 可根据实际情况及客 户需求而灵活设置。

[0048] 当切割工具 30切割指定切割对象吋， 若被切割部分出现下坠情况， 被切割部分 下坠吋产生的作用力会直接作用在切割工具 30上； 切割工具 30受力后， 其会将 力传递至转动臂 20上； 转动臂 20受力后， 其会带动卸荷回复件 40从初始区域 C转 至转动区域 D， 并根据其所受到的作用力的大小在转动区域 D内转动至相应的位 置， 以避免切割工具 30被下坠物压坏， 并借由卸荷回复件 41将其受到的作用力 衰减卸去； 而当转动臂 20上的作用力被衰减一定程度后， 若其力值小于卸荷回 复件 41自身的回复力， 此吋， 该卸荷回复件 41会根据转动臂 20上的作用力的衰 减变化而慢慢驱使转动臂 20从转动区域 D回至初始区域 C。 [0049] 另外， 当切割工具 30切割指定切割对象吋， 若切割对象某一部分因密度、 材料 等因素 （如大理石荒料的材质不均） 致使切割工具 30的切割阻力突然增大吋， 此刻， 切割工具 30会将其受到的作用力传递至转动臂 20上； 转动臂 20受力后， 其会带动卸荷回复件 41从初始区域 C转至转动区域 D， 并根据其所受到的作用力 的大小在转动区域 D内转动至相应的位置， 以避免切割工具 30被突然增大的阻力 损伤， 并借由卸荷回复件 41将其受到的作用力衰减卸去； 而当转动臂 20上的作 用力被衰减一定程度后， 若其力值小于卸荷回复件 41自身的回复力， 此吋， 该 卸荷回复件 41会根据转动臂 20上的作用力的衰减变化而慢慢驱使转动臂 20从转 动区域 D回至初始区域 C。
[0050] 综上可见， 本实施例中的切割设备的切割卸荷装置 100具有以下优点：
[0051] 1、 当切割工具 30切到较硬物质吋或者切割中卡死吋， 可理解地， 工作轮 31上 的金刚石串珠绳切到较硬物质吋或者切割中卡死吋， 其可借由卸荷回复件 41的 卸荷回复作用， 使到金刚石串珠绳得以缓冲， 减少损坏几率； 同吋地， 由于金 刚石串珠绳的损坏几率大大降低， 而由其引发的损坏溅出伤人事故也相应大大 降低， 有利于保证作业人员的安全性；
[0052] 2、 由于卸荷回复件 41在切割过程中起到张弛作用， 那么， 使到切割工具 30切 割吋就相对均匀有度， 而相应地， 切割工具 30的磨损消耗也会大幅降低， 有利 于提高切割工具 30的使用寿命， 降低成本， 提高切割效率； 同吋地， 还可减少 能源损耗成本、 人工成本以及机器使用成本； 再有， 与现有技术相比， 减少需 要经验丰富的技术人员操控切割设备的限制， 进一步地降低生产成本；
[0053] 3、 切割卸荷装置 100的设置使用， 可以对整个机器电路、 油路、 机械传动系统 起着一个缓冲作用， 而以此， 对于整个机器来说， 大大降低机器的维修率、 故 障发生率及保养成本； 同吋地， 可使到切割设备的连续工作吋间得到保障和延 长， 使机器在工作吋间内大大提高效率和产能， 从而大大降低人工成本， 提高 生产效率；
[0054] 4、 相对于现有技术中在遇到建筑物混凝土被切割部分下坠吋通过使某些部件 损坏以保全整机及切割工具的方式， 本申请中的切割卸荷装置 100的设置， 除了 无需损坏部件， 还有利于保证工作吋间的持续进行， 提高工作效率， 并降低生 产成本；
[0055] 5、 由于切割卸荷装置 100的设置， 可大大降低机器的整体承载能力的限制要求 ， 据此， 可减少制造材料的使用， 降低机器的整体重量， 从而使到机器更轻巧 ， 更便于运输组装， 而生产成本也更低， 价格更实惠。
[0056] 请再参阅图 1， 本实施例的卸荷回复件 41为拉簧 41a， 其中， 拉簧 41a也称作拉 伸弹簧或拉力弹簧， 其是承受轴向拉力的螺旋弹簧。 拉簧 41a—般都用圆截面材 料制造， 当然， 亦可使用矩形截面等的材料制造。 在不承受负荷吋， 拉簧 41a的 圈与圈之间一般都是并紧的没有间隙。 其中， 当转动臂 20位于初始区域 C吋， 拉 簧 41a为收缩合拢； 当转动臂 20转至转动区域 D吋， 拉簧 41a会根据转动臂 20传来 的作用力的大小而作相应的伸展张幵。 另外， 拉簧 41a取材方便， 安装也方便。
[0057] 那么， 当切割工具 30受压吋， 其也随着转动臂 20的转动而被牵拉伸展张幵， 以 将转动臂 20受压后传来的作用力缓冲衰减， 从而实现对切割工具 30卸荷的目的 ； 而当转动臂 20上的作用力被缓冲衰减一定程度后， 若其力值小于拉簧 41a自身 的弹性回复力， 此吋， 该拉簧 41a会根据转动臂 20上的作用力的衰减变化而慢慢 驱使转动臂 20从转动区域 D回至初始区域 C， 而拉簧 41a也随着转动臂 20从转动区 域 D回至初始区域 C而收缩合拢。

[0060] 而为了便于安装设置， 第一转动部 51设于转动臂 20的第一端 21的底端， 第二转 动部 52设于第一支撑臂 11的底端， 而第一转动部 51、 第二转动部 52组合连接， 即为一合页。 [0061] 当然， 第一转动部 51、 第二转动部 52的实施方式不限于此， 亦可将第一转动部 51设置为轴承或插轴， 而第二转动部 52对应为插轴或轴承。 其中， 插轴与轴承 之间的转动配合， 不但较好地实现转动臂 20的第一端 21与第一支撑臂 11之间的 转动设置， 而且还取材方便， 安装方便。
[0062] 下面结合各图式， 对本实施例的切割设备的切割卸荷装置 100的工作原理作进 一步说明：
[0063] 当切割工具 30切割指定切割对象吋， 若被切割部分出现下坠情况， 被切割部分 下坠吋产生的作用力会直接作用在切割工具 30上； 切割工具 30受力后， 其会将 力传递至转动臂 20上； 转动臂 20受力后， 其会带动卸荷回复件 40从初始区域 C转 至转动区域 D， 并根据其所受到的作用力的大小在转动区域 D内转动至相应的位 置， 以避免切割工具 30被下坠物压坏， 并借由卸荷回复件 41将其受到的作用力 衰减卸去； 而当转动臂 20上的作用力被衰减一定程度后， 若其力值小于卸荷回 复件 41自身的回复力， 此吋， 该卸荷回复件 41会根据转动臂 20上的作用力的衰 减变化而慢慢驱使转动臂 20从转动区域 D回至初始区域 C。
[0064] 另外， 当切割工具 30切割指定切割对象吋， 若切割对象某一部分因密度、 材料 等因素 （如大理石荒料的材质不均） 致使切割工具 30的切割阻力突然增大吋， 此刻， 切割工具 30会将其受到的作用力传递至转动臂 20上； 转动臂 20受力后， 其会带动卸荷回复件 41从初始区域 C转至转动区域 D， 并根据其所受到的作用力 的大小在转动区域 D内转动至相应的位置， 以避免切割工具 30被突然增大的阻力 损伤， 并借由卸荷回复件 41将其受到的作用力衰减卸去； 而当转动臂 20上的作 用力被衰减一定程度后， 若其力值小于卸荷回复件 41自身的回复力， 此吋， 该 卸荷回复件 41会根据转动臂 20上的作用力的衰减变化而慢慢驱使转动臂 20从转 动区域 D回至初始区域 C。

[0077] 实施例四：
[0078] 请参阅图 5， 实施例四的实施方式与实施例三的实施方式大同小异， 具体可参 阅实施例三的描述说明， 此处不作详述， 而两者的区别在于：
[0079] 在实施例三中， 卸荷回复件 41为拉簧 41a。
[0080] 支架 10还包括第二支撑臂 12b和第三支撑臂 13b， 第三支撑臂 13b位于转动臂 20 的上方并与转动臂 20相对设置， 且第三支撑臂 13b与位于初始区域 C吋的转动臂 2 0平行设置， 第二支撑臂 12b的一端部垂直连接于第一支撑臂 11， 第二支撑臂 12b 的另一端部连接于第三支撑臂 13b;
[0081] 拉簧 41a的一端部连接于第三支撑臂 13b上， 拉簧 41a的另一端部连接于转动臂 2 0上， 并靠近设于转动臂 20上的切割工具 30， 且拉簧 41a的中心线与位于初始区域 C吋的转动臂 20的中心线垂直相交。
[0082] 在实施例四中， 卸荷回复件 41为压簧 41b。 其中， 压簧 41b是承受轴向压力的螺 旋弹簧， 因能承受压力， 两端可为幵式或闭式或绕平或磨平， 它所用的材料截 面多为圆形， 也可用矩形和多股钢萦卷制的， 同吋， 弹簧有等节距和变节距的 。 压簧 41b的形状有圆柱形、 圆锥形、 中凸形和中凹形， 以及少量的非圆形乃至 各种尾端之变体。 压簧 41b的圈与圈之间有一定的间隙， 当受到外载荷吋弹簧收 缩变形， 储存变形能。
[0083] 支架 10还包括第二支撑臂 12c和第三支撑臂 13c， 其中， 需要说明的是， 实施例 四中的第二支撑臂 12c、 第三支撑臂 13c， 虽然其与实施例三中的第二支撑臂 12b 、 第三支撑臂 13b的名称相同， 但两者的设置位置、 功用不同； 第三支撑臂 13c位 于转动臂 20的下方并与转动臂 20相对设置， 且第三支撑臂 13c与位于初始区域 C 吋的转动臂 20平行设置， 第二支撑臂 12c的一端部垂直连接于第一支撑臂 11， 第 二支撑臂 12c的另一端部垂直连接于第三支撑臂 13c; [0084] 压簧 41b的一端部连接于第三支撑臂 13c上， 压簧 41b的另一端部连接于靠近切 割工具 30的转动臂 20上， 以保证压簧 41b在不影响切割工具 30工作的同吋， 可快 速接收由转动臂 20传来的作用力， 有利于对切割工具 30实现卸荷目的； 且压簧 4 lb的中心线与位于初始区域 C吋的转动臂 20的中心线垂直相交， 其中， 当转动臂 20位于初始区域 C吋， 压簧 41b为伸展张幵； 当转动臂 20转至转动区域 D吋， 压簧 41b会根据转动臂 20传来的作用力的大小而作相应的收缩合拢。
[0085] 那么， 当切割工具 30受压吋， 转动臂 20会带着切割工具 30向下转动， 并挤压压 簧 41b， 而压簧 41b会根据所受到的作用力大小而进行相应的收缩合拢， 并同吋 将转动臂 20传来的作用力缓冲衰减， 从而实现对切割工具 30的卸荷的目的； 而 当转动臂 20上的作用力被缓冲衰减一定程度后， 若其力值小于压簧 41b自身的弹 性回复力， 此吋， 该压簧 41b会根据转动臂 20上的作用力的衰减变化而慢慢驱使 转动臂 20从转动区域 D回至初始区域 C， 并随着转动臂 20从转动区域 D回至初始 区域 C而伸展张幵。
[0086] 实施例五：
[0087] 请参阅图 6， 实施例五的实施方式与实施例一的实施方式大同小异， 具体可参 阅实施例一的描述说明， 此处不作详述， 而两者的区别在于：
[0088] 在实施例五中， 切割卸荷装置 100还包括用以锁紧固定转动臂 20以使转动臂 20 固定在初始区域 C与转动区域 D之间的任一处位置的固定机构 50。
[0089] 借由固定机构 50的设置， 可使到转动臂 20固定在初始区域 C与转动区域 D之间 的任一处位置， 以可使转动臂 20转动设于第一支撑臂 11上随意调节为固定设于 第一支撑臂 11上。 由此， 若遇到优先考虑切割设备的加工效率的情况下， 那么 ， 可通过固定机构 50以使转动臂 20固定在初始区域 C， 而切割工具 30也会跟随转 动臂 20的固定而被固定， 此吋， 位于初始区域 C的切割工具 30具有最佳的切割效 率， 借此， 便可以使到整个切割设备调整为高加工效率的切割设备。
[0090] 较佳地， 本实施例中的固定机构 50包括一锁紧螺钉 （图中未标示） ， 锁紧螺钉 一端连接于转动臂 20， 另一端连接于第一支撑臂 11， 而锁紧螺钉的设置， 结构 简单， 安装方便。
[0091] 实施例六： [0092] 请参阅图 6和图 7， 实施例六的实施方式与实施例五的实施方式大同小异， 具体 可参阅实施例五的描述说明， 此处不作详述， 而两者的区别在于：
[0093] 在实施例五中， 固定机构 50包括一锁紧螺钉， 锁紧螺钉一端连接于转动臂 20， 另一端连接于第一支撑臂 11。
[0094] 在实施例六中， 固定机构 50包括减振垫件 51、 及用以使减振垫件 51固持定位的 固持件 52， 固持件 52连接固定在支架 10上， 且固持件 52设有一可供减振垫件 51 容置的容置槽 521， 容置槽 521包容转动臂 20与第一支撑臂 11之间连接处； 减振 垫件 51设于容置槽 521内， 并接触于转动臂 20和第一支撑臂 11两者。
[0095] 其中， 借由减振垫件 51的设置， 可根据实际需要， 而设置不同硬度。 如需要减 振垫件 51完全抵顶转动臂 20和第一支撑臂 11两者以使转动臂 20固定在初始区域 C ， 可选取邵氏硬度 70-100HA的减振垫件 51， 而此种情况大多为优先考虑切割设 备的加工效率的情况下； 如需要减振垫件 51对转动臂 20起到缓冲减振作用， 可 选取邵氏硬度 30-60HA的减振垫件 51。 同吋， 也可见， 减振垫件 51的设置， 可根 据实际情况及客户需求而灵活设置。
[0096] 另外， 该减振垫件 51可采用橡胶材料制成， 当然亦可采用其它塑胶材料， 或者 其它柔性减振材料制成。
[0097] 以上所述仅为本发明较佳的实施例而已， 其结构并不限于上述列举的形状， 凡 在本发明的精神和原则之内所作的任何修改、 等同替换和改进等， 均应包含在 本发明的保护范围之内。
