Description

Technical Field

[0001] This utility model relates to the field of safety protection equipment technology, specifically a glass curtain wall demolition device. Background Technology

[0002] Tempered glass is a type of prestressed safety glass with high strength and thermal stability. Window breakers are auxiliary escape tools for enclosed cabins, used to smash glass windows and doors. However, since high-rise curtain walls often use multi-layered insulated tempered glass, window breakers are not very effective at breaking it.

[0003] Publication 1: A breaching system, such as one disclosed in CN214971292U, includes: a breaching component configured to perform breaching operations; a pneumatic launching component configured to provide aerodynamic force to the breaching component to launch it, thereby enabling the breaching component to perform breaching operations; and a control component electrically connected to the pneumatic launching component and configured to control the opening and closing of the pneumatic launching component. The control component controls the pneumatic launching component to open, so that the pneumatic launching component provides aerodynamic force to propel the breaching component. The breaching component is launched under the action of the aerodynamic force provided by the pneumatic launching component and performs breaching operations. It has good breaching effect, strong adaptability to working environment, and is suitable for remote breaching.

[0004] Analysis: After installation and repeated use, the above-mentioned demolition system has shown significant effectiveness in demolition operations of high-rise glass curtain walls. However, we found that because the equipment needs to be installed on special vehicles such as fire trucks, these vehicles cannot quickly reach the scene in busy urban areas or on congested or narrow roads. In such situations, the danger can change in an instant, and failure to arrive at the scene in time can cause incalculable losses.

[0005] Publication 2: For example, the shoulder-mounted four-tube remote breaching system with announcement number CN215859258U includes several launching tubes with breaching components for window breaking operations; a base placed on one end of several launching tubes, with launching components inside the base to drive the breaching components; a shoulder support for supporting the base, a handle tube for activating the launching components, and a grip located below the base; the shoulder support, i.e., shoulder-mounted use, makes the remote breaching system more convenient to carry and use, and has strong applicability; the launching components in each launching tube can launch the breaching components located in the launching tube to penetrate and shatter, for example, tempered glass or glass curtain walls, thereby completing the task in special operations that requires breaking tempered glass to continue the work; multiple launching tubes can be connected together through auxiliary connecting components to meet the needs of penetrating multiple pieces of tempered glass multiple times, and has strong operability;

[0006] Analysis: Since the power unit of this device is an electronic detonation component, which contains a propellant, there is still room for improvement in its operational stability.

[0007] Therefore, we need to make technical improvements to the current demolition system to meet the usage requirements. Utility Model Content

The switch box mating surface is embedded in the lower guide rail mating surface and can move linearly along the lower guide rail. The switch box is equipped with push-button switches, and the number of push-button switches corresponds one-to-one with the number of transmitter tubes.

[0013] The grip seat has a top surface that is set as a grip seat mating surface. The grip seat mating surface is embedded in the lower guide rail mating surface and can move linearly along the lower guide rail. A grip is fixedly mounted on the side wall of the grip seat at an angle upward. A trigger is mounted on the grip. A switch button is mounted on the grip directly opposite the trigger. The button switch and the switch button are configured to activate the electric control valve after being triggered simultaneously.

[0014] The switch box is located between the shoulder rest and the grip base. A push rod mechanism is also provided between the switch box and the grip base to keep them moving together. A locking mechanism is also provided on the switch box to lock the switch box onto the mating surface of the lower guide rail.

[0015] The technical problem to be solved by this utility model can also be achieved through the following technical solution: the glass curtain wall demolition device described above, wherein the push rod mechanism includes a push rod seat and a push rod sleeve.
