CN203602244U - Cart travelling device of bridge crane - Google Patents

Abstract

The utility model relates to a cart travelling device of a bridge crane. No matter a three-in-one type cart travelling device or a QD type cart travelling device is adopted, the problem that a motor is easy to heat up to cause burning due to frequent backing braking operations during working is effectively solved. The cart travelling device of the special bridge crane for winery comprises a motor, a brake, a speed reducer, a coupling and wheels, which are sequentially connected. The cart travelling device is characterized in that a fluid coupling is arranged between the motor and the brake, as the fluid coupling 2 has the characteristics of underload starting, overload protection, impact buffering, flexibility in braking and energy saving, the phenomenon that the motor 1 is overheated to cause burning due to frequent backing braking operations is avoided when the cart travelling device is used in the winery, and the cart travelling device runs stably and is low in noise.

Description

A kind of cart running gear of crane in bridge type

Technical field

The utility model relates to a kind of bridge crane running gear.

Background technology

At present, known brewery hoisting crane used is concerning general brewery: it is few that goliath is used, twin beams is not generally used, many with single-beam crane, and the cart running gear of single-beam crane is with " three-in-one " form (configuration mostly is: Cone-shaped electric machine+LD retarder) in the majority, can meet the needs of general brewery.Concerning large-scale brewery: many (the considering the factors such as factory building scale, Jiao Chi arrange, operation is frequent) that twin beam overhead bridge crane is used, cart running gear mostly is traditional QD type cart operation.But being " three-in-one form " or traditional " QD pattern ", cart running gear all cannot effectively solve in the course of the work frequent " reverse-starting braking operation " phenomenon and the problem that causes motor easily to heat up so that burn.

Utility model content

Technical problem to be solved in the utility model is to provide one and can solves hoisting crane frequent " large anti-car " and cause motor easily to heat up so that the cart running gear of the crane in bridge type of the problem of burning.

For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: the cart running gear of the special crane in bridge type of a kind of brewery, comprise the motor, drg, retarder, coupler and the wheel that connect successively, its special feature is: between described motor and drg, hydraulic coupler is set.

Compared with prior art; the beneficial effects of the utility model are: between motor of the present utility model and transmission shaft, be provided with hydraulic coupler; fluid coupling has light start, overload protection, slows down the feature of impact, pliable and tough braking and power saving function; can protect motor by actv.; thereby while having solved brewery's operation, the frequent reverse-starting braking operation of hoisting crane causes motor easily to heat up and causes the problem of burning with playing braking; extend the period of service of motor; and hoisting crane noise in the course of the work reduces, the operation needs of brewery are met.

Accompanying drawing explanation

Fig. 1 is the utility model structural representation.

1. motor 2. hydraulic coupler 3. drg 4. retarder 5. coupler 6 wheels in Fig. 1.

The specific embodiment

Below in conjunction with the drawings and specific embodiments, the utility model is elaborated.

As shown in Figure 1, a kind of cart running gear of crane in bridge type, comprises the motor 1, drg 3, retarder 4, coupler 5 and the wheel 6 that connect successively, between motor 1 and drg 3, hydraulic coupler 2 is set.

In the time of work; because hydraulic coupler 2 has light start, overload protection, slows down the feature of impact, pliable and tough braking and power saving function; while being applied in brewery's operation, avoided because frequent reverse-starting braking operation, a braking make the phenomenon that motor 1 is overheated and even burn, and the noise that operates steadily is little.

Claims (1)

1. the cart running gear of the special crane in bridge type of brewery, comprise the motor (1), drg (3), retarder (4), coupler (5) and the wheel (6) that connect successively, it is characterized by: between described motor (1) and drg (3), hydraulic coupler (2) is set.
