Specific embodiment
Below in conjunction with attached drawing, by the way that a preferable specific embodiment is described in detail, the utility model is done and is further explained
It states.
The utility model discloses a kind of Machine guardings for crane collision resistant.The Machine guarding includes：
It is arranged at the collision arm of crane main body side and is arranged at the activity collision bar, fixed collision bar and limit of collision arm end
Bit switch.Collision arm is respectively equipped on adjacent cranes, and is correspondingly arranged in opposite directions, between adjacent cranes between collision arm
Distance is minimum so that when adjacent cranes are close to each other, collision arm is contacted or collided at first, and triggers the deceleration of place crane
It is acted with stopping, realizing the collision prevention function between adjacent cranes.
As shown in Figure 1, be the structure chart of the Machine guarding of one first crane in two neighboring crane, it includes
The first collision arm 103 being horizontally set on the first gantry body side wall, set on the upper surface of the first collision arm 103 there are three
The the first activity collision bar 101 set along 103 axial alignment of the first collision arm.First activity collision bar 101 of front end is set
The top on the first collision arm 103.All first activity collision bar, 101 sides are equipped with the limit with the linkage of the first activity collision bar 101
Bit switch.The top of the lower surface of first collision arm 103 is equipped with first and fixes collision bar 102.
As shown in Fig. 2, be the structure chart of the Machine guarding of one second crane in two neighboring crane, it includes
The second collision arm 203 being horizontally set on the second gantry body side wall, the upper top of 203 end of the second collision arm are equipped with the
Two fix collision bar 201, and lower end is equipped with several the second activity collision bars 202 set along 203 axial alignment of the second collision arm.Most
Second activity collision bar of front end is arranged on 203 times tops of the second collision arm.202 side of all second activity collision bars is equipped with and the
Two activity collision bars 202 linkage limit switch.
Above-mentioned two collision arms being separately positioned on the first crane and the second crane are oppositely arranged, and adjacent again
The first crane and the second crane on, the distance between 203 end of the first collision arm 103 and the second collision arm is minimum.
When the first crane and the second crane move toward one another, the first collision arm 103 and the second collision arm 203 are sent out at first
Raw contact, wherein the second of the second collision arm 203 fixes the first activity collision bar 101 of 201 and first collision arm 103 of collision bar
The first of the second activity collision bar 202 and the first collision arm 103 of corresponding collision or the second collision arm 203 fixes collision bar
102 correspond to collision.When the first activity collision bar 101 or the second activity collision bar 202 through collision activity are to trigger to link with it
Limit switch.Limit switch communicates to connect the control system of the first crane and/or the second crane, the limit switch being triggered
Collision alarm is uploaded to control system, control system receives collision alarm control crane and slows down and stop.Slow down and stopped
There are two slow down and a stop spacing by Cheng Zhongshe.
As shown in figure 3, the structure diagram for fixing the fixation collision bar 201 of collision bar 102 or second for first, the present embodiment
In first fix collision bar 102 with second fix 201 structure of collision bar it is identical, it includes connection collision arm the first fixed seat
301 and the fixation lance 302 that is fixedly connected in the first fixed seat 301.
It is the structural representation of the first activity collision bar 101 or the second activity collision bar 202 such as Fig. 4 and with reference to shown in Fig. 5
Scheme, the first activity collision bar 101 is identical with 202 structure of the second activity collision bar in the present embodiment, and it includes connection collision arms
Second fixed seat 401, movable lance 402, the spring 501 of connection activity lance 402 for being rotatablely connected the second fixed seat 401, with
And the movable bearing support 403 of connecting spring 501；Movable bearing support 403 is close to the first activity collision bar 101 or the second activity collision bar
202 corresponding limit switches are set, and the first activity collision bar 101 is hit by the second fixation collision bar 201 or the second activity is collided
When bar 202 is hit by the first fixation collision bar 102, movable lance 402, which rotates, drives spring 501, passes through 501 drive activity of spring
Bearing 403, which rotates, touches corresponding limit switch, and triggering limit switch uploads collision alarm to the control system of crane, control
First crane and/or the second crane slow down and stop, and avoid the first crane and the second gantry body moved toward one another
Collision.
