Description

Automatic expansion bolt mounting equipment Technical Field The invention belongs to the field of buildings, and particularly relates to automatic expansion bolt mounting equipment. Background After building bodies such as subway tunnels, culvert walls and the like are molded, expansion bolts are usually required to be installed, so that a fixed foundation is provided for the installation of pipeline parts such as subsequent communication cable pipelines, power pipelines, ventilation and water supply and drainage facilities and the like. At present, the installation operation of the expansion bolt is mainly performed manually, and the complete construction process of the expansion bolt is required to be subjected to a plurality of manual working procedures, namely, firstly, a screw hole is drilled on the surface of a building by hand-held impact drilling of an operator, the expansion bolt is manually planted into the hole after the drilling is completed, then, a nut on the expansion bolt is rotated by a spanner to realize the expansion fixation of the bolt, and after the expansion bolt is installed in place, a hanging component or a bracket is manually installed on the bolt so as to prepare for the installation of a subsequent hanging object. The manual construction method has the inherent defects that on one hand, the whole construction process is completed completely by relying on manpower, a large amount of labor cost is required to be input, the operation efficiency of manual drilling, bolt implantation, locking nut and mounting bracket is low, and large-scale and high-efficiency construction requirements are difficult to meet, on the other hand, when an operator is used for drilling a hole by hand-held impact drill, the drilling precision is insufficient due to the influence of equipment vibration, and when the operator works in high-altitude or narrow space, the impact drill is used and the bolt is mounted with certain potential safety hazards, and personnel injury accidents are easily caused. In order to solve the defects of manual construction, some automatic construction equipment for installing expansion bolts has appeared in the prior art, and the aim is to replace manual work to finish operations such as drilling, bolt implantation, locking and the like through a mechanical structure. However, the conventional automatic equipment still has obvious defects in design that in the installation process, the vertical lifting motion (for realizing the feeding motion of the bolt implanted in the hole) and the rotary locking motion (for realizing the locking and fixing of the nut) of the operation mechanism are required to be respectively and independently provided with corresponding power driving mechanisms. The design mode not only increases the integral structural complexity of the equipment and improves the assembly difficulty of parts, but also increases the later maintenance workload and maintenance cost of the equipment.
