The invention discloses a multifunctional mining intrinsic safety type loudspeaker box, and the sound box comprises a vehicle body, a mounting box body and an explosion-proof loudspeaker box body; a mounting vertical plate is fixedly mounted on the right side of the upper portion of a mounting bottom plate, a pull rod is mounted at the right end of the upper portion of the mounting bottom plate, and the mounting box body is mounted on the vehicle body. The explosion-proof sound box main body is installed in the installation box body, the top of the explosion-proof sound box main body is provided with an explosion-proof combination surface, and the interior of the explosion-proof sound box main body is divided into a first explosion-proof cavity and a second explosion-proof cavity through a partition plate. According to the multifunctional mining intrinsic safety type sound box, the vehicle body is arranged, a worker can pull the vehicle body through wheels at the bottom and a pull rod on the right side, and the position of the sound box can be freely changed; meanwhile, a reset spring is further installed between the pull rod and a mounting vertical plate, and when the vehicle body is pulled, the pull rod inclines rightwards under the action of a rotating shaft; when the vehicle body is not pulled, the pull rod automatically resets under the action of the reset spring, so the pull rod is prevented from influencing underground operation.
本发明公开了一种多功能矿用本安型音箱,包括车体、安装箱体和隔爆音箱主体,所述安装底板的上方右侧固定安装有安装立板,所述安装底板的上方右端安装有拉杆,所述安装箱体安装在车体的上方,所述隔爆音箱主体安装在安装箱体内部,所述隔爆音箱主体的顶部设有隔爆结合面,所述隔爆音箱主体内部通过隔板隔开形成第一隔爆腔和第二隔爆腔。该多功能矿用本安型音箱,设置有车体,工人可以通过底部的车轮以及右侧的拉杆对车体进行拉动,使得装置的位置可以自由移动,同时拉杆和安装立板之间还安装有复位弹簧,在拉动车体的时候拉杆在转轴的作用下向右倾斜,在不拉动车体时,在复位弹簧的作用下拉杆自动复位,防止拉杆对井下的作业造成影响。
