Description
技术领域 technical field
本实用新型涉及一种活动式动臂塔机安装钢丝绳，尤其适用于动臂塔机。 The utility model relates to a movable boom tower crane for installing a steel wire rope, which is especially suitable for a movable boom tower crane.
背景技术 Background technique
安装钢丝绳是指动臂塔机安装检修时，连接起重臂和塔顶保证起重臂在特定状态的钢丝绳。现在的动臂塔机安装钢丝绳是两端分别固定在起重臂和塔顶上，如图1所示，安装钢丝绳两端分别用销轴（螺栓）和起重臂、塔顶连接。起重臂、塔顶上两个连接点的钢丝绳长度不变。在塔机使用过程中，安装钢丝绳随着起重臂运动，由于钢丝绳重力及环境等各方面的因素的影响，随着起重臂的运动两个连接点的距离不断变化，安装钢丝绳凹下处容易和塔机的其它部件干涉、缠绕在一起，严重影响塔机的使用安全。 The installation wire rope refers to the wire rope that connects the boom and the top of the tower to ensure that the boom is in a specific state during installation and maintenance of the boom tower crane. The two ends of the installation wire rope of the current boom tower crane are respectively fixed on the boom and the top of the tower. As shown in Figure 1, the two ends of the installation wire rope are respectively connected with the boom and the top of the tower by pin shafts (bolts). The length of the wire ropes at the two connection points on the boom and the tower top remains unchanged. During the use of the tower crane, the installation wire rope moves with the boom. Due to the influence of various factors such as the gravity of the wire rope and the environment, the distance between the two connection points changes continuously with the movement of the boom. It is easy to interfere and get entangled with other parts of the tower crane, seriously affecting the safety of the tower crane.

为实现上述目的，本实用新型提供一种活动式动臂塔机安装钢丝绳，包括安装钢丝绳、滑轮组、配重组；所述滑轮组包括至少一个定滑轮和一个动滑轮；所述安装钢丝绳的一端固定在起重臂上，另一端绕经过定滑轮和动滑轮连接塔顶，且动滑轮上连接配重组，将起重臂和塔顶之间悬空的安装钢丝绳拉紧。进一步，所述的定滑轮设有一个。 In order to achieve the above purpose, the utility model provides a movable boom tower crane installation wire rope, including installation wire rope, pulley block, counterweight; the pulley block includes at least one fixed pulley and a movable pulley; one end of the installation wire rope is fixed together On the boom, the other end goes around the fixed pulley and the movable pulley to connect to the top of the tower, and the movable pulley is connected with a counterweight to tighten the installation wire rope suspended between the boom and the tower top. Further, there is one fixed pulley.
本实用新型动臂塔机安装钢丝绳活动设计，采用在固定塔顶的一端连接动滑轮，滑轮上连接配重组的方式，有以下几个技术优点：1、采用配重重力拉紧安装钢丝绳，滑轮组改变拉力的方向，配重仅上下移动，能有效的保证拉紧的效果；2、在使用过程中能够使起重臂和塔顶之间的钢丝绳不下凹，有效避免安装钢丝绳和结构干涉的情况；3、机构制造简单，安全可靠。 The movable arm tower crane of the utility model is designed to install steel wire ropes. It adopts the method of connecting a movable pulley at one end of the fixed tower top, and connecting a counterweight on the pulley. In the direction of the pulling force, the counterweight only moves up and down, which can effectively ensure the tensioning effect; 2. During use, the wire rope between the boom and the tower top can be prevented from sinking, effectively avoiding the installation of wire rope and structural interference; 3. The mechanism is simple to manufacture, safe and reliable.
