Abstract

A board feeding machine lifting device of a block making machine comprises a machine frame, a bracket and a worm speed reducer. The board feeding machine lifting device is characterized in that the worm speed reducer and a power shaft are installed at the top end of the machine frame and power is transmitted to the power shaft through the worm speed reducer. Due to the fact that the worm speed reducer is adopted, outage self-locking can be achieved due to the structure of the speed reducer, the bearing capacity of a 4 kw conic rotor motor of a prior structure can be achieved through a common 2.2 kw motor, cost is reduced, and the board feeding machine lifting device is safe and reliable. A toothless guide wheel is innovatively arranged at the lower end, a connection screw rod is adjusted, and therefore left and right balance of the bracket can be achieved, synchronism of the two ends is not influenced by the position accuracy of the power shaft and a chain wheel key groove any more, and the machining difficulty of a part is greatly reduced. According to the structure, the cost is saved, the safety performance is improved, power consumption is reduced, and the performance of an automatic board feeding machine is more stable.

Description

A kind of upper trigger bont of block machine

Technical field

The utility model relates to a kind of accessory equipment of block machine, relates in particular to a kind of upper trigger bont.

Background technology

In block machine production process, the effect of automatic plate loader is that supporting plate is pushed to and is sent in the middle of plate machine plate case, reduces artificial.In upper plate process, need frequent start-stop, require jacking system lifting synchronously steady, and possess auto-lock function.Under prior art condition, upper trigger jacking system is used cycloidal planetary gear speed reducer to drive synchronous sprocket wheel, requires the keyway of sprocket wheel, axle to have the synchronism that very high precision could realize lifting, and parts machining cost is higher.More self-locking performance is used conical rotor machine to join cycloidal planetary gear speed reducer realization and cuts off self-lock, but its cost is higher; Part is used band-type brake motor to join cycloidal planetary gear speed reducer, but this kind of motor enclasping force is difficult to adjustment, and safety factor is lower, now less use.

Summary of the invention

Technical problem to be solved in the utility model is the deficiency that overcomes background technology, and a kind of upper trigger bont of a kind of block machine of scientific and reasonable for structure, low cost of manufacture is provided.

The technical solution of the utility model is: a kind of upper trigger bont of block machine, comprise frame, bracket and worm speed reducer, it is characterized in that described frame top is equipped with worm speed reducer and dynamical axis, worm speed reducer by power transmission to dynamical axis.

The axis of guide is equipped with in described frame lower end, and sprocket wheel is equipped with at dynamical axis two ends, and track adjusting wheel is equipped with at axis of guide two ends, between sprocket wheel and track adjusting wheel, lifting chain is housed.

Described bracket is fixed on frame by road wheel activity and slides up and down along frame, and bracket one side is fixed by connection wire rod and lifting chain.

The utility model is owing to having adopted worm speed reducer, and the structure of reductor itself can provide and cut off self-lock, and the common 2.2kw motor of adapted can be realized the bearing capacity of original design 4kw conical rotor machine, has reduced cost, and safe and reliable.The employing of lower end novelty anodontia track adjusting wheel, can be by bracket left and right balance by adjusting connection wire rod, the positional precision of dynamical axis, sprocket wheel keyway is not affecting the synchronism at two ends, greatly reduces part difficulty of processing.This structure has been saved cost, has improved safety performance, has reduced consumption of current, and the performance that makes to build automatic plate loader is more stable.

Accompanying drawing explanation

Fig. 1 is the utility model structural representation.

Accompanying drawing indicates explanation:

In figure, 1 is reductor, and 2 is dynamical axis, and 3 for promoting sprocket wheel, and 4 is lifting chain, and 5 is connection wire rod, and 6 is road wheel, and 7 is track adjusting wheel, and 8 is the axis of guide, and 9 is bracket, and 10 is frame.

The specific embodiment

For making the art personnel better understand the technical solution of the utility model, below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.

As shown in Figure 1, a kind of upper trigger bont of block machine, comprises frame 10, bracket 9 and worm speed reducer 1, it is characterized in that described frame 10 tops are equipped with worm speed reducer 1 and dynamical axis 2, worm speed reducer 1 by power transmission to dynamical axis 2.

The axis of guide 8 is equipped with in described frame 10 lower ends, and sprocket wheel 3 is equipped with at dynamical axis 2 two ends, and track adjusting wheel 7 is equipped with at the axis of guide 8 two ends, and 7 of sprocket wheel 3 and track adjusting wheels are equipped with lifting chain 4.Described bracket 9 is fixed on frame 10 by road wheel 6 activities and slides up and down along frame 10, and bracket 9 one sides are fixing with lifting chain 4 by connection wire rod 5.

During concrete use, worm speed reducer 1 by power transmission to dynamical axis 2, thereby drive dynamical axis 2 to rotate, dynamical axis 2 drives lifting chain 4 to rotate, and lifting chain 4 drives bracket 9 liftings, when bracket 9 rises to desired location, just close down worm speed reducer 1, because used worm speed reducer 1, there is auto-lock function, even if close down worm speed reducer 1 bracket 9, can not decline yet.
