Abstract
The utility model is related to a kind of derrick crane safety device, including gravity briquetting, pressure switch, drawstring composition.It is characterized in that：The pressure switch is arranged in the traveling control system of derrick crane and is connected with derrick crane traveling control power supply, the gravity briquetting is arranged on above pressure switch, one end of the drawstring is connected with track fixture, and the other end is connected with gravity briquetting.During derrick crane walking operation, track fixture is hung on derrick crane with hook, when hook comes off due to rocking, track fixture is slid downwards under its own Action of Gravity Field, and drawstring is tensed and by gravity briquetting pull-up, pressure activated switch, disconnect derrick crane running gear power supply, it is stopped, the utility model is easy to operate, makes operation process more safe and reliable.
Description
First, technical field：
The utility model is related to a kind of servicing unit, particularly a kind of derrick crane safety device.
2nd, background technology：
Derrick crane is usually used in the lifting work in Large-scale Construction Project, and for safety, derrick crane exists
With track fixture by itself and walking track fixation, in the prior art the track fixture on derrick crane after end-of-job
One end is fixed on derrick crane with bearing pin, and hook is connected with the track fixture other end, is linked up with when crane job
By the hanging of track fixture on crane, because derrick crane is when walking operation, the hook of track fixture is during rocking
It is easy to come off, makes track fixture stuck in orbit, cause security incident.
3rd, utility model content：
The utility model uses a kind of derrick crane of safety in view of the shortcomings of the prior art, propose a kind of simple in construction
Safety device.
The technical scheme that the utility model is used：
The utility model is related to a kind of derrick crane safety device, including gravity briquetting, pressure switch, drawstring group
Into；It is characterized in that：The pressure switch be arranged on derrick crane traveling control system on and with derrick crane traveling control
Power supply processed is connected, and the gravity briquetting is arranged on above pressure switch, and described drawstring one end is connected with track fixture, another
End is connected with gravity briquetting.
The beneficial good effect of the present apparatus：The present apparatus is simple in construction, with good function of safety protection.
4th, illustrate
Fig. 1：Patent assembling schematic diagram of the present invention.
5th, embodiment
Embodiment one：Referring to Fig. 1, the utility model is related to a kind of derrick crane safety device, including gravity pressure
Block 2, pressure switch 3, drawstring 4 are constituted.It is characterized in that：The pressure switch 3 is arranged on the traveling control system of derrick crane
Above and with derrick crane traveling control power supply it is connected, the gravity briquetting 2 is arranged on the top of pressure switch 3, the drawstring 4
One end be connected with track fixture 1, the other end is connected with gravity briquetting 2.During derrick crane walking operation, with hook 5
Track fixture 1 is hung on derrick crane, when hook 5 comes off due to rocking, track fixture 1 is in its own Action of Gravity Field
Lower to slide downwards, drawstring 4 is tensed and by the pull-up of gravity briquetting 2, and pressure switch 3 starts, and disconnects derrick crane running gear electricity
Source, is stopped, and the utility model is easy to operate, makes operation process more safe and reliable.
