Description
Technical field
The utility model relates to tower crane technical fields, especially prevent tower crane steel cable from leading to the inspection of disconnected rope because of part fracture of wire
Survey device.
Background technique
It is used to the tower crane of handling article in construction site, happen occasionally disconnected rope phenomenon.Article weighing several tons falls from high-altitude
It falls and easily causes major accident.
The disconnected rope of tower crane is broken because steel cable bearing capacity itself is insufficient, and usually steel wire is old in long-time service
Change, breakage occurs in part (usually first one disconnected) steel wire, when sliding on pulley, because of the broken steel wire exposing in part, pierces certain
Place, this root is slack, and other when continuing sliding, this root are further torn, then after being run multiple times, cut is more and more tighter
Weight, related other also there is fracture of wire, block to knot at original fracture of wire suddenly, in the case where weight and motor strength pull,
Steel cable is broken, is caused the accident.
It is also to have omen, as long as disconnected rope omen, most of disconnected rope can be found in advance though disconnected rope is moment
It is avoidable.
Summary of the invention
It, can be in tower crane operation the utility model proposes preventing tower crane steel cable from leading to the disconnected detection device restricted because of part fracture of wire
In delicately in time discovery tower crane steel cable fracture of wire.
The utility model uses following technical scheme.
Prevent tower crane steel cable from leading to the detection device of disconnected rope because of part fracture of wire, the detection device is equipped with logical for steel cable
The detection hole crossed；The inner wall of the detection hole is close to steel cable outer surface；Inflatable structure is equipped at the outer wall of the detection hole；It is described
Inflatable structure includes deformation induction device；The deformation induction device is connected with alarm device；The tower crane steel cable liter when tower crane work
Path is dropped by detection hole, if the disconnected steel wire that Wire Rope Surface appears punctures inflatable structure and inflatable structure gas leakage is made to generate deformation；Then
Deformation induction device, which is triggered, makes alarm device alarm.
The inflatable structure is pneumatic tire；Pneumatic tire inner ring forms detection hole；The inner ring wall of pneumatic tire is with thickness
Wear-resistant material forms, and the tyre sidewall other than inner ring wall is the thin-wall construction easily punctured.
The deformation induction device includes the deformation sensing chip to connect with tire outer ring.
Camera is equipped with by the detection hole to observe the steel cable at detection hole.
The camera is connected with data cable with tower crane control room.
Powder is filled in the pneumatic tire to enhance visual effect when tire is punctured gas leakage.
The pneumatic tire is set to the fixed pulley side of tower crane；The camera is set at the bracket of tower crane fixed pulley.
The utility model it is simple for structure, implementation cost is low, can find steel cable fracture of wire position in time, and steel cable fracture of wire is made
It is sounded an alarm for disconnected rope omen, so as to allow staff to handle in time, efficiently reduces the disconnected rope probability of steel cable.
The utility model is not modified tower crane mechanism, therefore will not interfere to the normal work of tower crane.
Detailed description of the invention
With reference to the accompanying drawings and detailed description to the further details of explanation of the utility model:
Attached drawing 1 is the schematic diagram of the utility model；
In figure: 1- detection hole；2- inflatable structure；3- breaks steel wire；4- steel cable；5- fixed pulley；6- camera；7- deformation induction
Device.
Specific embodiment
As shown in Figure 1, preventing tower crane steel cable from leading to the disconnected detection device restricted because of part fracture of wire, the detection device is equipped with
The detection hole 1 passed through for steel cable 4；The inner wall of the detection hole is close to steel cable outer surface；It is equipped at the outer wall of the detection hole
Inflatable structure 2；The inflatable structure 2 includes deformation induction device 7；The deformation induction device is connected with alarm device；Work as tower crane
Tower crane steel cable lift path is by detection hole when work, if the disconnected steel wire 3 that Wire Rope Surface appears punctures inflatable structure 2 and ties inflation
Structure gas leakage generates deformation；Then deformation induction device, which is triggered, makes alarm device alarm.
The inflatable structure 2 is pneumatic tire；Pneumatic tire inner ring forms detection hole；The inner ring wall of pneumatic tire is with thickness
Wear-resistant material forms, and the tyre sidewall other than inner ring wall is the thin-wall construction easily punctured.
The deformation induction device includes the deformation sensing chip to connect with tire outer ring.
Camera 6 is equipped with by the detection hole to observe the steel cable at detection hole.
The camera is connected with data cable with tower crane control room.
Powder is filled in the pneumatic tire to enhance visual effect when tire is punctured gas leakage.
The pneumatic tire is set to 5 side of fixed pulley of tower crane；The camera is set at the bracket of tower crane fixed pulley 5.
Embodiment:
During tower crane lifts cargo with steel cable, steel cable lift path passes through detection hole；If the fracture of wire position of steel cable
Pneumatic tire is punctured when passing through detection hole, then is had a flat tire so that its volume rapid drop, so that being originally pressed in tire outer ring
The deformation sensing chip of the elasticity at place is mobile, triggers deformation induction device, alarm device alarm, and tower crane stops working, site safety people
Member observes the steel cable at tire by camera, accurately to confirm steel cable fracture of wire position so as to subsequent processing.
When tire is punctured, the powder of pre-fill is escaped with air-flow in tire, and site safety personnel can more directly see
The position that tire is punctured is observed, to more rapidly find the fracture of wire position of steel cable.
Since be possible to upward may also downward for steel cable fracture of wire, and steel cable is oscilaltion when lifting cargo, therefore
Whether in lifting process, or in the process that lifting cargo is put down, this product can the fracture of wire position to steel cable examine
It surveys.
