Protective device for bridge site construction
The protection device comprises two stand columns, first guide grooves are formed in the inner end faces of the stand columns, the section of each first guide groove is arranged to be in a right trapezoid shape, second guide grooves are formed in the inner walls of the rear ends of the first guide grooves, and first stop blocks are arranged in the first guide grooves; second stop blocks are fixed to the rear ends of the first stop blocks through bolts, the second stop blocks are arranged in the second guide grooves, a same protection frame is fixed between the two first stop blocks through bolts, a protection net is fixed in the protection frame through bolts, a speed reducing mechanism is arranged in the first guide grooves, and the speed reducing mechanism is connected with the first stop blocks; a discharging mechanism is arranged on the stand column, and a push-back mechanism is arranged on the discharging mechanism. The second stop block and the first stop block can make contact with the inner walls of the second guide groove and the first guide groove correspondingly, so that the effect of first deceleration and then stop is integrally formed, and damage to the protective net caused by falling of broken stones is effectively reduced.
本发明涉及一种用于桥梁工地施工用防护装置，包括两个立柱，所述立柱内端面开设有第一导向槽，第一导向槽截面设置成直角梯形，第一导向槽后端内壁开设有第二导向槽，第一导向槽内设置有第一止停块，第一止停块后端通过螺栓固定有第二止停块，第二止停块设置于第二导向槽内，两个第一止停块之间通过螺栓固定有同一个防护框，防护框内通过螺栓固定有防护网，第一导向槽内设置有减速机构，减速机构和第一止停块之间连接，立柱上设置有排料机构，排料机构上设置有回推机构；本发明利用第二止停块和第一止停块会分别和第二导向槽以及第一导向槽的内壁接触，从而整体形成先减速后止停的效果，从而有效降低碎石下落对防护网的损伤。
