The invention relates to a safe communication tower with deicing and anti-climbing functions. The tower comprises a supporting column, a platform, an antenna, a deicing mechanism and a prevention mechanism; the deicing mechanism comprises a rotating component, a lifting component and a deicing component, and the prevention mechanism comprises a reciprocation component and a rotating component. According to the safe communication tower with the deicing and anti-climbing functions, by means of the deicing mechanism, an ice layer around the antenna is cleaned away uniformly and comprehensively, the phenomenon that a load of the antenna is increased by the ice layer, so that the antenna collapses is prevented, use of the communication tower is affected, and the phenomenon that the ice layer falls from height, and then life and property safety of people around can be threatened is avoided; by means of the prevention mechanism, a cat ladder can stop after jittering and rising to certain height, a cross rod of the cat ladder is turned over by certain angle, the phenomenon that children make direct contact with the cat ladder is avoided, the children are prevented from climbing, the safetyprotection effect is achieved, and practicability and safety of the communication tower are improved.

The invention discloses a high-efficiency and environment-friendly data collection and transmission instrument, which includes a mounting plate and a transmission instrument main body. A plurality of Internet interfaces are embedded in the lower part of the transmission instrument main body, and a display screen is embedded in the front surface of the transmission instrument main body. The outer surface of the main body of the transmission instrument is fixed with two relatively distributed mounting pieces, and the bottom of the front surface of the mounting plate is also fixed with a plurality of stable components corresponding to the Internet interface, and each of the Internet interfaces There are two stabilizing components opposite to each other; a telescopic component is installed between the mounting plate and the mounting piece; the present invention facilitates the safety protection effect on the main body of the transmission instrument through the setting of the telescopic component, avoiding the The main body of the transmission instrument is damaged during the operation; the invention can make the connection between the cross network cable and the Internet interface more stable through the setting of the stabilizing component, and avoid the trouble of reconnecting and setting the cross network cable accidentally dropped.

The invention discloses a high-altitude stabilization device for building exterior wall construction. Check, if there is a damaged position of the rope, it needs to be replaced; the upper end of the rope is connected to the top of the building, the lower end of the rope is fixed with the ground, and a safety wire is matched between the two ropes. The safety rope is also made of nylon rope. When choosing the safety rope, the diameter needs to be slightly smaller than the diameter of the rope; when the device is in use, it is necessary to keep the rope vertical, and the ropes on both sides can stabilize the hanging basket. It can still achieve stable support; make aerial work safer.

The invention discloses a mixer blanking device for building construction, which comprises a container arranged above the mixer, the diameter of the container is not smaller than the diameter of the mixer, and an axis block is arranged at the bottom axis of the container, so that A plurality of connecting rods are welded between the axis block and the container, a fan-shaped area is formed between two adjacent connecting rods, and a metal screen is welded in the formed fan-shaped area; There is a support structure, and there is a quick-release structure between the support structure and the container; this product can be assembled on the top of the mixer, and the raw materials are screened while discharging.

The invention discloses an emergency brake device for a hoist, which comprises a box body, an inner cavity is arranged inside the box body, and stepped holes communicating with the inner cavity are arranged on both sides of the box body, through the step The hole is equipped with a rotating shaft, and a bearing is matched between the rotating shaft and the stepped hole. One end of the rotating shaft is inserted into the inner cavity, and the other end is located outside the box body. The end of the rotating shaft located outside the box body A connecting sleeve is provided, and the outside of the connecting sleeve is processed with a threaded hole, a fixed engaging disc is processed on the right rotating shaft, and a movable engaging disc is matched on the left rotating shaft; the structure of this product is relatively simple, and the cost is low.
