The invention discloses a construction method of an aerological overhanging template supporting frame body. The aerological overhanging template supporting frame body comprises an overhanging steel supporting platform and a template supporting frame, the overhanging steel supporting platform comprises a plurality of upper part overhanging steel girders, steel wire rope suspension devices are arranged on the upper parts of the upper part overhanging steel girders, and oblique supporting devices are arranged on the lower parts of the upper part overhanging steel girders. The construction methodof the aerological overhanging template supporting frame body comprises the steps that 1, the overhanging steel supporting platform is set up; 2, load test of the overhanging steel supporting platformis carried out; 3, a lower part frame body of the overhanging steel supporting platform is sealed; 4, a template supporting frame is set up; and 5, the template supporting frame is sealed. The construction is convenient and fast, the safety is good, the stability of the overhanging steel supporting platform can be effectively improved, the overhanging steel supporting platform is prevented from deforming, so that the template supporting frame on the upper part of the overhanging steel supporting platform is prevented from overturning, meanwhile, the load test is carried out on the overhangingsteel supporting platform, it is ensured that the overhanging steel supporting platform has enough bearing capacity, and the safe operation of the construction is ensured.

The invention relates to the technical field of special equipment, and discloses a two-way progressive brake safety tongs, in which a force plate is movably sleeved on the outer surface of the center shaft, the number of force plates is two, and one end of the force plate is fixed A trigger is installed, and the outer surface of the coil drum is in contact with the outer guide rail. When the device is working, the triggers on the upper and lower sides will move simultaneously, so that the brake bar will continue to collide with the trigger on the other side for a second time after hitting the upper trigger, making the braking effect more obvious. At the same time, the brake bar The self-rotating force generated when hitting the upper trigger can be transmitted to the contact position between the lowered trigger and the outer guide rail, so as to avoid the force plate on one side taking the axis of the central axis as the center of rotation due to too severe impact Rotation causes the position of the trigger to deviate and loses the frictional force between the outer guide rail and the whole device loses its effect, which improves the working stability of the device.

The invention discloses a portable experimental power source device, comprising a box body, a handle arranged on the box body, and rollers arranged at the bottom of the box body. A power module, an inverting module, a transforming module, a control switch and a socket are arranged in the box body. The control switch is an earth leakage protective switch or an overcurrent protective switch; the socket includes a first socket and a second socket, the power module, the control switch, the inverting module and the first socket are connected in succession, the first socket, the transforming module and the second socket are connected in succession, and the power module is rechargeable. In the invention, automatic power-off is achieved by adding the control switch to a circuit.

The invention discloses a multifunctional power floating plate, comprising a floating plate, an illumination lamp and a splitter block, wherein the illumination lamp is arranged on the outside of thefloating plate. The multifunctional power floating plate has the advantages: through a DC motor, a motor shaft, a fixed impeller, a propeller, a battery, a protective cover and a connecting rod, the device obtains power, so that the floating plate can be moved and used according to the needs of users; by means of a No. 1 fixing ring, a No. 1 elastic rope, a No. 1 wristband, a No.2 retaining ring,a No.2 elastic rope and a No.2 bracelet, the user can be connected to the floating plate, and when the floating plate is far away from the user, the floating plate can be pulled back in time; througha No. 1 switch, a No. 2 switch and a main switch, the device can only be moved by both hands, so as to avoid the floating plate and the personnel side-turning caused by one-handed operation of the user, thereby causing casualties; and through the USB conversion plug and the storage slot, the mobile phone can be charged in real time to meet the needs of the user.

The invention discloses a window escape clamp cantilever and a method of installing the cantilever. The clamp cantilever includes a locking nut, a slide clamp arm, a pull arm, a fixing clamp arm and a supporting cantilever; one end of the pull arm is provided with outer thread, and the thread circumference is provided with at least a cutting plane; the other end of the pull arm and the fixing clamp arm form an angle less than or equal to 90 degrees, and are fixed and connected; the fixing clamp arm and the supporting cantilever are connected; the supporting cantilever is provided with a hole and / or a hook, which is connected with other lifesaving equipments; one end of the slide clamp arm is provided with a through hole, the size of which adapts to the cross section of a thread part of the pull arm, so that the slide clamp arm can slide back and forth on the thread part of the pull arm, but not rotate; the slide clamp arm and the fixing clamp arm are on the same side of the circumference of the pull arm; the locking nut can rotate at the thread part of the thread part of the pull arm, so that the slide clamp arm can slide back and forth on the pull arm. The clamp cantilever of theinvention is characterized by simple structure, convenient installation, high reliability, strong bearing capacity, etc., and can be used as a piece of general equipment for escaping from indoor disaster in high-rise buildings.
