Problems solved by technology

However, due to the limitation of the installation position of the commonly used speed locker at present, the volume of the designed product should not be too large. The use method of the speed locker in conjunction with the conventional support and its structural factors lead to a slower trigger locking speed and a smaller locking force. , the defect of higher production cost

Embodiment Construction

[0013] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0014] Embodiments of the present invention: when implementing a method of improving the triggering speed and locking force of the speed locker of the present invention, as figure 1 As shown, the method is to first make an applicable body composed of a fixed body and a sliding body (the fixed body and the sliding body can be made according to actual installation requirements), and an induction device composed of a speed locker (the speed locker can use existing market finished product of speed locker for sale), safety device (safety device can adopt conventional safety buckle, safety pin and other devices), actuator linked with induction device, locking device with interlocking tooth block; The body undergoes relative displacement under the vibration of the building, and the sensing device senses the relative moving speed of the applicable body. When t...

Abstract

The invention discloses a method and device for increasing the triggering speed and locking force of a speed locker, which comprises an applicable body composed of a fixed body and a sliding body, a sensing device composed of a speed locker, a safety device, and an execution device linked with the sensing device. device, a locking device with interlocking tooth blocks; the fixed body and the sliding body of the applicable main body undergo relative displacement under the vibration of the building, and the sensing device senses the relative moving speed of the applicable main body. When the vibration is too large and the moving speed exceeds the set When the value is fixed, the induction device breaks through the safety device and provides an initial trigger driving force to push the actuator to perform mechanical locking. Force self-locking. The invention has the advantages of simplicity, reliability, strong applicability, fast trigger locking speed, large locking force and low production cost.

Description

technical field [0001] The invention relates to a method and a device for increasing the triggering speed and locking force of a speed locker, belonging to the technical field of structural protection. Background technique [0002] Speed ​​lockers are commonly used in engineering structures such as bridges and houses. It is a piston-type cylindrical cavity structure. Through the action of high-viscosity fluid filled in the cavity, the resistance generated between the cylinder and the piston at low speed is very small, and the resistance increases rapidly as the speed increases. As high as the design value, the functions of relative displacement at low speed and low speed at high speed between the connecting members at both ends are realized. However, due to the limitation of the installation position of the commonly used speed locker at present, the volume of the designed product should not be too large. The use method of the speed locker in conjunction with the convention...
