Description
技术领域technical field
本发明属于建筑工程技术领域,涉及一种用于塔吊的轨道支撑系统。The invention belongs to the technical field of construction engineering and relates to a rail support system for a tower crane.
背景技术Background technique
塔吊是建筑工地上最常用的一种起重设备又名“塔式起重机”,以一节一节的接长简称“标准节”,用来吊施工用的钢筋、木楞、混凝土、钢管等施工的原材料。塔吊是工地上一种必不可少的设备。Tower crane is the most commonly used lifting equipment on construction sites, also known as "tower crane". Raw materials for construction. Tower crane is an indispensable equipment on the construction site.
塔吊可分为移动式塔式塔吊和固定式塔吊。移动式塔式塔吊根据行走装置的不同又可分为轨道式、轮胎式、汽车式、履带式四种。轨道式塔式塔吊塔身固定于行走底架上,可在专设的轨道上运行,稳定性好,工作效率高,因而广泛应用于建筑安装工程。轮胎式、汽车式和履带式塔式塔吊无轨道装置,移动方便,但不能带负荷行走、稳定性较差。Tower cranes can be divided into mobile tower cranes and fixed tower cranes. Mobile tower cranes can be divided into four types: track type, tire type, car type, and crawler type according to different traveling devices. The track-type tower crane is fixed on the walking chassis and can run on a specially designed track. It has good stability and high work efficiency, so it is widely used in construction and installation projects. Tire-type, car-type and crawler-type tower cranes have no track device and are easy to move, but they cannot walk with a load and have poor stability.
固定式塔式塔吊根据装设位置的不同,又分为附着自升式和内爬式两种,附着自升塔式塔吊能随建筑物升高而升高,适用于高层建筑,建筑结构仅承受由塔吊传来的水平载荷,附着方便,但占用结构用钢多;内爬式塔吊在建筑物内部电梯井、楼梯间,借助一套托架和提升系统进行爬升,顶升较繁琐,但占用结构用钢少,不需要装设基础,全部自重及载荷均由建筑物承受。Fixed tower cranes are divided into two types: attached self-elevating type and internal climbing type according to different installation locations. The attached self-elevating tower crane can rise with the rise of the building, which is suitable for high-rise buildings. It bears the horizontal load transmitted by the tower crane and is easy to attach, but it takes up a lot of steel for the structure; the internal climbing tower crane climbs in the elevator shaft and stairwell inside the building with the help of a set of brackets and a lifting system. The jacking is more cumbersome, but The occupied structure uses less steel and does not need to install foundations, and all self-weight and loads are borne by the building.
无论是移动式塔吊还是固定式塔吊,要么依靠塔吊底部与地面固定实现载荷承受,要么是建筑物完成承受载荷,因此稳定性均有待提高,也因如此,制约了塔吊负荷量的提高。Whether it is a mobile tower crane or a fixed tower crane, either rely on the bottom of the tower crane to be fixed to the ground to achieve load bearing, or the building completes the load bearing, so the stability needs to be improved, and because of this, the increase in the load capacity of the tower crane is restricted.

The other end is connected to the slide rail assembly 2. The slide rail assembly 2 includes a slide rail 3 and a slider 4 that is compatible with the slide rail 3 and can walk along the slide rail 3. The cross section of the slide rail 3 is C-shaped Or H-shaped, the slide rail 3 is fixedly connected to the building 102, and the slide block 4 is connected to the end of the beam 1.
本发明的工作原理是:横梁1与滑轨组件2连接,滑轨组件2固定在建筑物102上,塔吊100通过横梁1得到支撑,横梁1通过滑轨组件2及建筑物102得到支撑,从而提高了塔吊100在吊装时的稳定性和负荷量。横梁1的端部通过滑轨组件2实现滑动连接,在现有技术中,可移动式吊机100的底部设有行走机构103,行走机构103可以是轮子、履带或导轨等,在本实施例中,行走机构优选为导轨,该导轨与滑轨组件2平行设置,由于横梁1起到支撑作用,因此塔吊100可以带负荷行走,在行走过程中塔吊100在横梁1的轴向上的受力得到支撑。The working principle of the present invention is: the beam 1 is connected with the slide rail assembly 2, the slide rail assembly 2 is fixed on the building 102, the tower crane 100 is supported by the beam 1, and the beam 1 is supported by the slide rail assembly 2 and the building 102, thereby The stability and load capacity of the tower crane 100 during hoisting are improved. The end of crossbeam 1 realizes sliding connection through slide rail assembly 2, and in the prior art, the bottom of movable crane 100 is provided with running gear 103, and running gear 103 can be wheel, crawler belt or guide rail etc., in this embodiment Among them, the traveling mechanism is preferably a guide rail, which is arranged in parallel with the slide rail assembly 2.

本实施例与实施例1的结构和工作原理基本相同,不同之处在于,如图5、图13和图14所示,横梁1上设置有一个能调整横梁1长度的轴向距离调整机构14,所述的横梁1包括前臂15和后臂16,前臂15和后臂16上套设有套管17且套管17分别与前臂15和后臂16可拆卸的固定连接。The structure and working principle of this embodiment and embodiment 1 are basically the same, the difference is that, as shown in Figure 5, Figure 13 and Figure 14, an axial distance adjustment mechanism 14 capable of adjusting the length of the beam 1 is provided on the beam 1 , the crossbeam 1 includes a front arm 15 and a rear arm 16, the sleeve 17 is sheathed on the front arm 15 and the rear arm 16, and the sleeve 17 is detachably fixedly connected with the front arm 15 and the rear arm 16 respectively.
塔吊100在行走时,与滑轨组件2之间的距离会产生变化,而横梁1的长度是固定的,因此,如果横梁1的长度不可调节,则塔吊100与滑轨组件2之间就会产生卡固现象,导致塔吊100不能正常行走,因此,本实施例设计了一个能自动调整塔吊100与滑轨组件2之间的距离的轴向距离调整机构14,轴向距离调整机构14包括活动套18,所述的活动套18连接有支撑杆19且支撑杆19远离活动套18的一端与塔吊固定连接或与滑块4连接,所述的活动套18一端与横梁1固定连接形成定位端20,另一端与支撑杆19活动连接,或所述的活动套18一端与支撑杆19固定连接形成定位端20,另一端与横梁1活动连接。活动套18内且在定位端20上固定有顶紧油缸21。When the tower crane 100 is walking, the distance between the tower crane 100 and the slide rail assembly 2 will change, but the length of the beam 1 is fixed. Therefore, if the length of the beam 1 cannot be adjusted, the distance between the tower crane 100 and the slide rail assembly 2 will be The clamping phenomenon occurs, causing the tower crane 100 to not be able to walk normally. Therefore, this embodiment designs an axial distance adjustment mechanism 14 that can automatically adjust the distance between the tower crane 100 and the slide rail assembly 2. The axial distance adjustment mechanism 14 includes a movable A sleeve 18, the movable sleeve 18 is connected with a support rod 19 and the end of the support rod 19 away from the movable sleeve 18 is fixedly connected with the tower crane or connected with the slider 4, and one end of the movable sleeve 18 is fixedly connected with the beam 1 to form a positioning end 20, the other end is movably connected with the support rod 19, or one end of the movable sleeve 18 is fixedly connected with the support rod 19 to form a positioning end 20, and the other end is movably connected with the beam 1. A jacking oil cylinder 21 is fixed in the movable sleeve 18 and on the positioning end 20 .
如图5所示,当顶紧油缸21工作时,支撑杆19与横梁1顶紧,实现固定连接,当顶紧油缸21不工作时,支撑杆19与横梁1之间存在空隙,支撑杆19能沿着活动套18前后移动从而调整塔吊100与滑轨组件2之间的距离,也即调整横梁1的轴向距离,起到自动消除轴向偏差的效果,防止塔吊100在行走时被卡死。如图13所示,横梁1能沿着活动套18前后移动。如图14所示,横梁1的前臂15与活动套18固定连接,而支撑杆19一端能能沿着活动套18前后移动,另一端与滑块4铰接。As shown in Figure 5, when the jacking cylinder 21 works, the support rod 19 is tightly connected to the crossbeam 1 to realize a fixed connection. It can move back and forth along the movable sleeve 18 to adjust the distance between the tower crane 100 and the slide rail assembly 2, that is, to adjust the axial distance of the beam 1, so as to automatically eliminate the axial deviation and prevent the tower crane 100 from being stuck when walking die. As shown in FIG. 13 , the beam 1 can move forward and backward along the movable sleeve 18 . As shown in FIG. 14 , the forearm 15 of the beam 1 is fixedly connected with the movable sleeve 18 , and one end of the support rod 19 can move forward and backward along the movable sleeve 18 , and the other end is hinged with the slider 4 .
