Abstract
The utility model relates to a perpendicularlifting tipping preventing alarm for atower crane. The alarm comprises a measuring ruler, an infrared ray point projector and an alarm assembly, wherein the alarm assembly comprises a panel; buzzers, a leveler, an indicator and an angular scale located below the indicator are arranged on the panel; fixed contacts are further mounted on two sides of the indicator, and the fixed contacts and the buzzers are connected with a battery arranged on the back of the panel through lines; a track is mounted on the top surface of the panel; and the measuring ruler is mounted on the track, and the infrared ray point projector is arranged on one side of the measuring ruler. The alarm can timely provide informationthat a tipping accident is to happen when the perpendicularityexceeds of the standardby 2 permillageduring operation, an operator is reminded in a pre-warning manner and stops operation forrectification instantly, so that the tipping accident is avoided, and the perpendicular lifting tipping preventing alarm has the characteristics of simple structure, small size, simplicity in operation, portability and the like.
Description
Technical field
The utility model relates to Architectural Equipment technical field, particularly relates to the anti-tipping annunciator of the vertical jacking of a kind of tower crane.
Background technology
Along with the develop rapidly of construction trade, tower crane has become a kind of indispensable vertical transport instrument, and its safe operation also becomes the important indicator of construction trade safety in production.But in recent years, various places tower crane overthrow accident occurrence frequency is ascendant trend linearly, trace it to its cause and can not strictly control the deviate 2 ‰ that squareness allows in strict accordance with national standard for: operating personal self.The tower crane using in a lot of engineerings, controls squareness and need to adopt transit survey, and still, in fact, most of operating personals just rely on sensation or experience to operate, and causing can not strict controller excursion degree.Successively, provide a kind of simple to operate, instrument easy to carry replaces the datagram alarm device of " sensation operation " and " experience operation ", and whole cargo handling operation is controlled, and is that various places are in administrative responsibile institution and work unit and the long-awaited thing of personnel.
Summary of the invention
The purpose of this utility model is to overcome the defect of above-mentioned prior art, provides a kind of and can provide warning when operation, and operating personnel is rectified a deviation in time, and simple in structure, simple to operate, the anti-tipping annunciator of the vertical jacking of tower crane easy to carry.
For realizing the technical scheme that above-mentioned utility model object takes, be:
The anti-tipping annunciator of the vertical jacking of a kind of tower crane, it is characterized in that this annunciator is comprised of measuring scale, infrared ray cultellation device and annunciator assembly, wherein said annunciator assembly comprises panel, on this panel, be provided with buzzer phone, horizon equipment, pointer and be positioned at the angle scale of pointer below, in pointer both sides, fixed contact is also installed, described fixed contact is connected by the circuit battery set with back side of panel with buzzer phone; Described panel end face is provided with track; Above-mentioned measuring scale is installed in orbit, and infrared ray cultellation device is arranged on measuring scale one side.
The described measuring scale back side is provided with magnet.
On described infrared ray cultellation device, trimming handle is installed.
The principle that the utility model utilizes infrared ray cultellation provides data accurately for squareness, warning device is exactly according to these data, the contact switch of warning to be fixed on certain angle scale, if angle scale deviation exceeds at 2 ‰ o'clock, pointer will be encountered the contact being fixed on angle scale, reaches the object of warning.The anti-tipping annunciator of the vertical jacking of the utility model tower crane, when operation, can provide in time perpendicularity deviation to exceed the information that overthrow accident will occur standard at 2 ‰ o'clock, by the mode of early warning, remind operating personal " danger ", the correction that stops operation immediately, thus the generation of overthrow accident avoided.
The anti-tipping alarm arrangement of the vertical jacking of the utility model tower crane is simple, and volume is little, simple to operate, easy to carry.

Fig. 2 is the anti-tipping annunciator structure of the vertical jacking of the utility model tower crane simplified schematic diagram;
Fig. 3 is the lateral plan of annunciator assembly in the utility model;
Fig. 4 is installation site and the using method figure of the anti-tipping annunciator Facad structure of the vertical jacking of the utility model tower crane simplified schematic diagram.
The specific embodiment
The anti-tipping annunciator of the vertical jacking of tower crane of the present utility model is comprised of measuring scale 1, infrared ray cultellation device 2 and annunciator assembly, wherein annunciator assembly comprises panel 4, on described panel 4, be provided with the angle scale 7 of buzzer phone 5, horizon equipment 6, pointer 10 and pointer 10 belows, in pointer 10 both sides, be also provided with fixed contact 9, this fixed contact 9 is connected by the circuit battery 11 set with panel 4 back sides with buzzer phone 5; Described panel 4 end faces are provided with track 12.During combination, first pack infrared ray cultellation device 2 into measuring scale 1 one sides, and trimming handle 3 is set finely tunes, then measuring scale 1 is inserted in the top rail 12 of annunciator assembly, at this moment vertical, the anti-tipping annunciator of jacking of tower crane has just formed, as shown in Figure 1.Measuring scale 1 back side is provided with magnet 8.
In use, first the anti-tipping annunciator A of the vertical jacking of tower crane there is is the one side of magnet to be pull-in on a jiao of crane mast section B top, as shown in Figure 4.Measuring scale 1 is pulled out to suitable distance (in 30cm).Open infrared ray cultellation device 2, watch the level of horizon equipment 6 to be as the criterion.Check that pulling out the reading of measuring scale 1 and infrared ray cultellation device 2 throws poor at tower body baseplane point actual size reading, shown in Fig. 4 solid line, just can know the value of present height vertical missing.For example: known present height is that 30 meters of control criterion 2 ‰ permissible variations are in 6 centimetres.Measuring scale 1 is pulled out to 30cm, check that infrared ray cultellation device 6 is 38 centimetres in the outer back gauge of tower body baseplane subpoint high standard joint, as shown in Figure 4, it is now know that exceeds 2 centimetres to reversing sense deviation.If movable alarm device at this moment.Make its subpoint control to 36 centimetres, in 2 ‰.So, pointer 10 will point to an angle.This angle is exactly our selected annunciator.Fixed contact 9 is fixed on to the pointer point of this angle, then warning device is found to level fixes.At this moment pointer can be encountered namely contact switch of fixed contact 9(), buzzer phone can send sound and report to the police, and tells operating personnel to rectify a deviation, and can not continue operation, thereby realize pre-anti-tipping object.
