Abstract

The utility model discloses an upper and lower layer anti-collision device for a crane. The device comprises two sets of laser displacement sensor devices, and is characterized in that a first laser displacement sensor and a second laser displacement sensor which are obliquely arranged downwards are respectively arranged on two sides of the upper crane; and reflecting plates are respectively arranged on two lower cranes on two sides of the lower part correspondingly. According to the device, compared with the prior art, the structure does not have complex change, the related data are operated by intelligent equipment in the operating process, and corresponding motion control is performed, so that the operation is convenient, the data are accurately processed, the safety of the crane is improved, and the working efficiency is greatly improved under the condition.

Description

A kind of hoisting crane upper-lower-layer anti-collision device

Technical field

The utility model relates to a kind of mechanical anticollision device.

Background technology

For adapting to the needs of modern building technology, the hoisting crane that a lot of industrial enterprise use in the workshop, the two-layer hoisting crane in up and down is arranged between same standdle carrier, solve with this trouble that hoisting crane is built, the efficient of raising work, but this hoisting crane is dispatched and is remarkable, than being easier to occur collision case, causes personnel's life to threaten and property damage.And overhead traveling crane use frequent, on-the-spot dust also large, noise is large, especially night work, sight line is dim, industrial accident more easily occurs.By analysis, the reason that accident occurs has very that major part is that the safety device that hoisting crane carries does not work, or does not just install due to collision prevention device at all.Therefore study a kind of safe and reliablely, crown block anti-collision that can smooth operation hits system's important in inhibiting.Make a general survey of other traditional mechanical type collision prevention device, although simple in structure, cost is low, protected distance limit is worked unreliable, and Installation and Debugging are inconvenience also.

The utility model content

The purpose of this utility model is to provide a kind of hoisting crane upper-lower-layer anti-collision device of colliding between the hoisting crane levels of realizing preventing more accurately.

In order to realize above purpose, the utility model by the following technical solutions:

A kind of hoisting crane upper-lower-layer anti-collision device, comprise two cover laser displacement sensor devices, it is characterized in that: be separately installed with the first laser displacement sensor and the second laser displacement sensor that is tilted to lower setting in hoisting crane both sides, upper strata, and be equipped with respectively a reflecting plate on two lower floor's hoisting cranes of corresponding both sides in its lower section.

The angle of described reflecting plate and horizontal surface is 45 °, can certainly be 30 °, 60 °, 50 ° or 40 ° etc.

Adopt the utility model, structurally compare now too not complicated variation, and related data is all to be generated by intelligent equipment in the middle of working process, and carry out corresponding motion control, therefore operate more conveniently, simultaneously accurate data are processed, and also make the safety of hoisting crane also be improved, under this prerequisite, work efficiency also can have greatly improved.

Description of drawings

Fig. 1 is structural representation of the present utility model;

Fig. 2 is the laser displacement sensor circuit diagram.

As mark in figure: 1 is the first laser displacement sensor, 2 is the second laser displacement sensor, 3 is the upper strata hoisting crane, and 4 is the first reflecting plate, and 5 is the second reflecting plate, 6 is first lower floor's hoisting crane, 7 is second lower floor's hoisting crane, and LT1 is that laser displacement sensor is controlled contact, and KA1 is intermediate relay, S11 is emergency switch, and H01 is combined aural and visual alarm.

The specific embodiment

Below in conjunction with each the drawings and specific embodiments, the utility model is described further.

As shown in Figure 1:

A kind of hoisting crane upper-lower-layer anti-collision device, described device has comprised two cover laser displacement sensors, the upside of crane system comprises a upper strata hoisting crane 3, and the first laser displacement sensor 1 and the second laser displacement sensor 2 that tilt under oblique arranged respectively in the both sides of upper strata hoisting crane; And comprise first lower floor's hoisting crane 6 and second lower floor's hoisting crane 7 at the crane system downside, lower floor's hoisting crane towards the direction of the laser displacement sensor of upper strata hoisting crane respectively correspondence the first reflecting plate 4 and the second reflecting plate 5 are installed.

As shown in Figure 2: the structure interconnecting wiring diagram of laser displacement sensor, it comprises laser displacement sensor contact LT1, emergency switch S11, combined aural and visual alarm H01 and intermediate relay KA1, and wherein laser displacement sensor control contact LT1, emergency switch S11 and intermediate relay KA1 three are connected on same branch road; Contact, combined aural and visual alarm H01 that intermediate relay KA1 controls are connected on same branch road, and final above-mentioned two branch circuit parallel connections together.

Above-mentioned hoisting crane is in the middle of working process, and the first laser displacement sensor and the second laser displacement sensor send laser, and receives the laser reflection from the first reflecting plate and the second reflecting plate.when levels crane horizontal distance less than certain distance (according to the cart running velocity, can adjust) time, laser sensor is accepted the reflecting plate signal on lower floor's hoisting crane, begin action, the laser displacement sensor that it is often opened is controlled contact LT1 and is connected, time-delay coil KA1 gets electric connection, combined aural and visual alarm H01 gets electric, report to the police, remind the hoisting crane chaufeur to note, (also can be set as traveling mechanism of the larger traveller slows down or stops the time-delay of time-delay coil KA1 delayed contact, here be set as the input of cart frequency converter failure) control cart running condition, thereby guarantee the safety in operational process.And in figure, emergency button S11 can be spacing at the needs shielding laser according to actual conditions, if want to stop its alarm signal, press and can make its stop alarm this moment.
