Through optimizing inner structure, strengthened inner structure's fixity, have bigger flexibility, simultaneously, further improved inner structure's stability, improved the characteristics of wholeness ability, simple structure, the practicality is strong.

摘要：【中文】本实用新型公开了一种具有膨胀螺栓加固的锁脚锚杆支护结构，包括钢架、锚杆和膨胀螺栓；所述钢架两侧设置有供锚杆插入的定位插孔，底部向下延伸设置有间隔设置的限位引导条；所述锚杆包括穿入插孔内的插入部以及嵌设在限位引导条之间的承托部，所述承托部与钢架底部相抵以支撑钢架；所述插入部一端与承托部固定连接，另一端与膨胀螺栓固定连接。本设计通过焊接膨胀螺栓使得新型锚杆具有更强的锚固效果，以便对坑道周边围岩提供较大的支护抗力，防止围岩产生有害的过度变形，增加与钢拱架的整体性，使钢拱架和锁脚锚杆之间的连接更加牢固，极限承载能力得到提高；而插孔和限位引导杆则是对锚杆安装位置进行限位，实现精准支护。 【EN】The utility model discloses a foot-locking anchor rod supporting structure reinforced by expansion bolts, which comprises a steel frame, an anchor rod and expansion bolts; positioning insertion holes for inserting anchor rods are formed in two sides of the steel frame, and limiting guide strips arranged at intervals extend downwards from the bottom of the steel frame; the anchor rod comprises an inserting part penetrating into the inserting hole and a bearing part embedded between the limiting guide strips, and the bearing part is abutted against the bottom of the steel frame to support the steel frame; one end of the inserting part is fixedly connected with the bearing part, and the other end of the inserting part is fixedly connected with the expansion bolt. The novel anchor rod has a stronger anchoring effect by welding the expansion bolt, so that greater supporting resistance is provided for surrounding rocks around the gallery, harmful excessive deformation of the surrounding rocks is prevented, the integrity of the steel arch centering is increased, the connection between the steel arch centering and the foot-locking anchor rod is firmer, and the limit bearing capacity is improved; and the jack and the limiting guide rod limit the mounting position of the anchor rod, so that accurate support is realized.

摘要：【中文】本实用新型涉及声屏障安装技术领域，特别是声屏障安装操作台车，设置走行小车，在走行小车上设置至少两对纵向走行轮，以满足走行小车能够在沿钢轨进行移动，通过设置横移换道机构，在车体下方设置多个升降部件，横移换道机构还包括至少两对设置在车体下方的横向走行轮和两根垂直于两条钢轨的中心线的临时导轨；换道时，使升降部件伸出后，在钢轨的上方，一对横向走行轮的下方固定设置一根临时导轨，使升降部件收缩，使所有横向走行轮与临时导轨相接触，推动走行小车沿临时导轨的设置方向移动到目的线路上。这种方式相对于备用一台汽车吊作为换线使用的方式，大大节约了成本，解决了声屏障安装操作平台需要频繁换线的问题。 【EN】The utility model relates to a sound barrier installation technical field, especially sound barrier installation operation platform truck sets up walking dolly, sets up two pairs at least vertical walking wheels on walking dolly to satisfy walking dolly can move along the rail, through setting up sideslip lane change mechanism, sets up a plurality of lifting units below the automobile body, sideslip lane change mechanism still includes two pairs at least sets up in the automobile body below horizontal walking wheels and two temporary guide rails perpendicular to the central line of two rails; when the track is changed, after the lifting component extends out, a temporary guide rail is fixedly arranged below the pair of transverse traveling wheels above the steel rail, the lifting component contracts, all the transverse traveling wheels are in contact with the temporary guide rail, and the traveling trolley is pushed to move to a target line along the arrangement direction of the temporary guide rail. Compared with a mode that one spare truck crane is used for line changing, the mode greatly saves the cost and solves the problem that the line needs to be changed frequently when the sound barrier is installed on the operation platform.
