Abstract
The invention discloses an anti-collision device with an energy consumption function for a herringbone tower crane, which comprises two supporting arms and a buffer rubber, wherein each supporting arm comprises a steel channel and a buffer steel channel; the first ends of the buffer steel channels are connected to the first ends of the steel channels in a frictional slide mode; the second ends of the steel channels are fixedly connected to the stable position of a building structure; the second ends of the two buffer steel channels are connected through a rotary louver; and the buffer rubber is fixedly connected to the second ends of the two buffer steel channels. In the actual application, the anti-collision device with the energy consumption function for the herringbone tower crane is installed between a protected object and a tower crane; when the large arm of the tower crane collides with the buffer rubber, the buffer rubber can prolong the collision time and reduce impact force; and simultaneously, the buffer steel channels consume a large amount of impact energy through frictional slide, can further prolong the collision time, reduce the impact force and lighten the rebound of the supporting arms on the large arm of the tower crane, thereby reducing the influence of collision on the tower crane and the large arm of the tower crane.
Description
Technical field
The present invention relates to a kind of tower crane collision prevention device, refer in particular to a kind of chevron pointing tower crane collision prevention device with power consumption function.
Background technology
Tower crane is mainly used in the installation of vertical and the horizontal feed and the building element of material in the housing construction.Newly-built, renovating and enlarging engineering gets more and more in the building dense district at present, and the accident of colliding between tower crane and old building, tower crane and tower crane happens occasionally.In order to reduce to collide, generally can inhibiting device be installed on tower crane, but this limiting device often can not be worked well under the situation of power failure or strong wind to tower crane and both injuries of building.
Summary of the invention
Design goal of the present invention is, a kind of chevron pointing tower crane collision prevention device with power consumption function is provided.
For reaching above-mentioned purpose, the chevron pointing tower crane collision prevention device that the present invention has the power consumption function comprises two hold-down arms, described hold-down arm comprises a channel-section steel and a buffering channel-section steel, but first end of described buffering channel-section steel is connected in first end of described channel-section steel in the mode of Frictional Slipping, second end of described channel-section steel is fixed in the stable place of building structure, rotates louver by one between described two buffering channel-section steels, second end and is connected; One yielding rubber is fixed in second end of two described buffering channel-section steels.
Further improvement of the present invention is, the first end dos-of first end of described channel-section steel and described buffering channel-section steel is placed, in the superimposed scope of described channel-section steel and described buffering channel-section steel, offer a notch, in described notch, described channel-section steel is connected with described buffering channel-section steel by a plurality of bolts.
Further improvement of the present invention is that also second end of described buffering channel-section steel is connected with a steel plate, and described yielding rubber is fixed on the described steel plate.
In the practical application, the chevron pointing tower crane collision prevention device that the present invention is had the power consumption function is installed between protection object and the tower crane, and when the big arm of tower crane collided yielding rubber, yielding rubber can prolong the time of collision, reduce impulsive force, simultaneously, the buffering channel-section steel consumes a large amount of impact energys by Frictional Slipping, the time of collision can further be prolonged, reduce impulsive force, and alleviate the bounce-back of hold-down arm, and then reduce to collide influence tower crane and the big arm of tower crane to the big arm of tower crane.
Description of drawings
Fig. 1 is the front view that the present invention has the chevron pointing tower crane collision prevention device of power consumption function.
Fig. 2 is that the chevron pointing tower crane collision prevention device that the present invention has a power consumption function shows lateral plan.
Fig. 3 is the specific embodiment scheme drawing that the present invention has the chevron pointing tower crane collision prevention device of power consumption function.
The specific embodiment
Referring to shown in Figure 1, the chevron pointing tower crane collision prevention device 1 that the present invention has the power consumption function mainly comprises a yielding rubber 10 and two hold-down arms 20.
Hold-down arm 20 is made up of a channel-section steel 21 and a buffering channel-section steel 22, first end 211 of channel-section steel 21 is placed (web that is both stacks mutually) with first end, 221 dos-s of buffering channel-section steel 22, cooperate shown in Figure 2, in the superimposed scope of channel-section steel 21 and buffering channel-section steel 22, offer a notch 30, in notch 30, channel-section steel 21 is connected with buffering channel-section steel 22 by a plurality of bolts 40, when hold-down arm 20 was collided, buffering channel-section steel 22 can slide in notch 30 by friction.Rotate louver 60 by one between two hold-down arms 20 and be connected, the both sides of rotating louver 60 are weldingly fixed on respectively on the diapire of two hold-down arms, 20 buffering channel-section steels 22.Second end 222 of buffering channel-section steel 22 is welded with a steel plate 50, and yielding rubber 10 is bonded and fixed on the steel plate 50.
Referring to shown in Figure 3, for preventing that construction elevator 70 is subjected to the collision of the big arm 81 of tower crane of tower crane 80, the chevron pointing tower crane collision prevention device 1 that the present invention is had a power consumption function is installed between construction elevator 70 and the tower crane 80 and with the big arm 81 of tower crane and is in sustained height, earlier second end 212 of hold-down arm 20 channel-section steels 21 is welded or is bolted to the stable place of building structure during installation by built-in fitting, yielding rubber 10 is installed again, after the installation, on the rotation direction of the big arm 81 of tower crane, yielding rubber 10 just in time is between construction elevator 70 and the big arm 81 of tower crane.When the big arm 81 of tower crane collides yielding rubber 10, yielding rubber 10 can prolong the time of collision, reduce impulsive force, simultaneously, buffering channel-section steel 22 consumes a large amount of impact energys by friction slip in notch 30, the time of collision can further be prolonged, reduce impulsive force, and alleviate the bounce-back of 20 pairs of big arms 81 of tower crane of hold-down arm, and then reduce to collide influence tower crane 80 and the big arm 81 of tower crane.If collision back yielding rubber 10 is damaged, can change at any time.
