Embodiment Construction

[0022] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0023] Such as figure 1 , figure 2 , image 3 , Figure 4 As shown, the present invention designs and manufactures the stressed pin shaft 3 into a resistance strain gauge type structure with dual functions of force bearing and inductive weight change, and uses four resistance strain gauges to form a balance bridge. Tare off, so that the bridge is in a balanced state, and there is no voltage signal output. When the crane lifts the heavy object, the pressure of the heavy object causes the pin shaft 3 to slightly deform, which destroys the balance relationship of the electric bridge, thus generating a voltage signal proportional to the load. At this time, the trans...

Abstract

The invention provides a shackle with overload protection function and belongs to the field of hoisting machinery. Due to the special use occasions, complex hoisting environment and methods, the safety requirements for hoisting shackles are getting higher and higher, and it is urgent to develop a shackle product with overload protection function. The present invention is composed of a "U"-shaped shackle body, a shaft sleeve, a pin shaft, a shackle nut, a safety pin, a wireless transmitting instrument, a wireless receiving control instrument and a large-screen display; the shaft sleeve is placed on the "U"-shaped shackle body In the middle of the "U" shape of the pin, the two are set in the middle of the pin shaft as a whole; one end of the pin shaft has a built-in wireless transmitter, and the other end of the pin shaft is fastened by a shackle nut, and a safety pin is installed on the shackle nut. The design and manufacture of the pin shaft is a resistance strain gauge structure with dual functions of force bearing and sensing weight change, wireless transmitting instrument and wireless receiving control instrument transmit signals, and overload alarm.

Description

technical field [0001] The invention relates to a shackle with an overload protection function, which belongs to the field of hoisting machinery. Background technique [0002] Due to the special occasions of use and the complex hoisting environment and methods, the safety of the shackle is particularly important. At present, large-tonnage shackles are often used in key projects, but it is very complicated and unrealistic to weigh the loads one by one, resulting in frequent overloading. In order to prevent accidents, it is urgent to develop a shackle with overload protection function. The product, if the overload reaches a certain percentage during hoisting, it will send out an alarm to improve the safety of hoisting operations. Contents of the invention [0003] The purpose of the present invention is to provide a shackle with an overload protection function in order to solve the problem that the prior art cannot realize overload early warning protection. [0004] In ord...
