In order to achieve the purpose, the invention adopts the following technical scheme:
a mechanical impact overload protection device comprises an upper movable support, an impact body, an energy absorption body and a lower movable support;
the upper movable support is used as a bearing body of the impact body, the lower end of the impact body is a conical surface made of carbon steel or low-alloy structural steel, and the two sides of the section at the center of the conical surface are α degrees;
the lower movable support is used as a bearing body of the energy absorption body, the upper end of the energy absorption body is provided with a conical groove with an angle of β degrees, the angle of β degrees is smaller than the angle of α degrees, and the tip of the lowest point of the conical groove is provided with a groove for increasing destructiveness.
Preferably, the centers of the upper movable support and the lower movable support are both provided with round holes for fixing, and nuts for fixing the upper movable support and the impact body and fixing the lower movable support and the energy absorber are arranged in the round holes.
Preferably, the lower end of the energy absorber is provided with a damage groove for increasing destructiveness, and the thickness between the top of the damage groove and the bottom of the groove determines the absorption of the rated overload impact load.
Preferably, the periphery of the lower movable support is provided with flange holes for connection.
The invention has the beneficial effects that: the impact-bearing contact surface of the invention is firm and wear-resistant after special heat treatment, and when the invention is impacted by overload, the internal energy absorber can absorb the set rated impact load to damage the self, thus only a small part of the overload impact load acts on the protected structure, thereby prolonging the service life of the protected structure and more efficiently playing the role of overload protection. The invention has simple structure, firmness, durability and low price.

fig. 2 is a schematic structural diagram of an embodiment of an overload protection device against mechanical impact according to the present invention.
In the figure: the energy absorber comprises an upper movable support 1, an impact body 2, an energy absorber 3, a lower movable support 4, bolts 5, rubber rings 6 and protected structural flanges 7.
Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.
In the description of the present invention, it is to be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", and the like, indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, are merely for convenience in describing the present invention and simplifying the description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus, should not be construed as limiting the present invention.
Referring to fig. 1, the overload protection device against mechanical impact comprises an upper movable support 1, an impact body 2, an energy absorber 3 and a lower movable support 4;
the upper movable support 1 is used as a bearing body of the impact body 2, the lower end of the impact body 2 is a conical surface made of carbon steel or low-alloy structural steel, the two sides of the section at the center of the conical surface are α degrees, the conical surface at the lower end of the impact body 2 is used for transmitting overload impact load, and the firmness of the conical surface at the lower end of the impact body 2 can be increased through heat treatment;
wherein, the lower movable support 4 is used as a bearing body of the energy absorber 3, the upper end of the energy absorber 3 is provided with a conical groove with an angle of β degrees, and the angle of β is smaller than the angle of α degrees, the angle of β is smaller than the angle of α, so that when the impact body 2 moves downwards, the conical surface at the lower end of the impact body 2 can transmit overload impact load to the side wall of the conical groove with an angle of β degrees, thereby realizing the overload protection function by destroying the energy absorber 3, the tip of the lowest point of the conical groove is provided with a groove for increasing destructiveness, and the destructiveness of the impact body 2 can be increased by arranging the groove, thus the energy absorber 3 can be more easily broken;
furthermore, the lower end of the energy absorber 3 is provided with a destructive groove for increasing destructiveness, and the thickness between the top of the destructive groove and the bottom of the groove determines the size of the absorbed rated overload impact load, namely when the energy absorber is subjected to mechanical impact, the impact force is transmitted to an β angle surface, when the horizontal component force is larger than the rated load force which can be absorbed by the cross-sectional area at the width b, the energy absorber is rapidly broken and destroyed, and the overload protection function is realized in a self-destruction mode, wherein the energy absorber 3 is made of low-toughness steel, so that the toughness is low and the energy absorber is easy to destroy, and the overload protection function is realized.
It should be noted that: 1. go up movable support 1 and lower movable support 4 center department and all offer the round hole that is used for fixing, and be provided with in the round hole and be used for movable support 1 and the impact body 2 fixed with the nut that lower movable support 4 and energy-absorbing body 3 are fixed, can guarantee through the setting of nut that movable support 1 and impact body 2 are fixed and lower movable support 4 and energy-absorbing body 3 are fixed, and adopt the mode of nut to be convenient for the dismantlement and the change of impact body 2 and energy-absorbing body 3.
