The invention discloses a building load-bearing steel pipe bending alarm device, comprising a wall body, a fixing plate is fixedly arranged on the left end surface of the wall body, the fixing plate is provided with a movement mechanism, and the movement mechanism comprises a sliding mechanism arranged on the fixing plate. The first slider on the left end face of the plate, the left end face of the first slider is fixed with a fixed box, the fixed box is provided with an air cavity, the inner wall of the right side of the air cavity is fixed with a first motor, the air cavity There are sliding plates sliding between the inner walls of the upper and lower sides of the cavity. The invention detects the bending degree of the load-bearing steel pipe through the built-in top block. When the load-bearing overload causes the bending degree to exceed the set range, the push block is used to restrain the steel pipe from continuing to bend, and the alarm is used to detect the bending degree of the steel pipe. The early warning can effectively alleviate the collapse accident caused by the bending of the steel pipe, and at the same time, it can immediately warn the workers to evacuate, so as to avoid threats to personal safety.

The invention discloses a stable-supporting type automobile lift. The stable-supporting type automobile lift comprises a plurality of supporting rods, an inner rotating rod, a limiting plate, a gyrating plate, an electric pushing rod, and a rotating device for driving the inner rotating rod to rotate, wherein the gyrating plate is fixedly arranged on the electric pushing rod; the lower end of theinner rotating rod is rotatably connected to the upper end of the electric pushing rod; the limiting plate is fixedly connected to the inner rotating rod in a sleeving manner; the lower ends, surrounding the inner rotating rod, of the multiple supporting rods circumferentially pass through the limiting plate and are in sliding connection with the gyrating plate; an annular rail fitting the multiple supporting rods is formed in the upper surface of the gyrating plate; the multiple supporting rods are fixedly connected to the limiting plate; the rotating device is fixedly arranged on the electric pushing rod. According to the stable-supporting type automobile lift, the four supporting rods and the inner rotating rod are treated as five supporting points for stably supporting an automobile, so that the automobile in repairing can be prevented from deviating and falling down; the inner rotor is driven to rotate through a motor; the four supporting rods are driven through the limiting plateto slide along the annular rail, and thus the automobile can be stably supported even during the automobile angle adjusting.

The invention provides a safety protection device of a current-conducting rod. The safety protection device of the current-conducting rod comprises a protection cover, wherein the protection cover is coated with insulation paint and comprises a framework and a plurality of protection strips; the framework is a cuboid or cube or cylinder framework; the protection strips are arranged on the top face of the framework; the bottom face of the framework is fixed to a furnace body of a resistance furnace; the two ends of each protection strip are fixed to the framework; intervals through which connection cables connected with the current-conducting rod pass are formed between the protection strips. According to the safety protection device of the current-conducting rod, the connection cables can be spaced with the furnace body by a certain distance, and the connection cables are prevented from being softened by high temperature of the furnace body, affecting the normal use and shortening the service life. The safety protection device of the current-conducting rod can avoid injuries caused when personnel touch the connection cables by mistake, and the safety protection device is coated with the insulation paint, so that the production safety is further improved.
