Abstract

The utility model discloses a stopping device for a lifter, which comprises a lifter transmission shaft, a ratchet wheel fixedly arranged at an end of the transmission shaft, a detent matched with the ratchet wheel and a fixing seat for fixing the detent. As the ratchet wheel and the detent only rotate toward a direction, when the lifter works normally, in case of power cut or replacement of a motor decelerator, a hopper of the lifter does not rapidly slide downward due to unbalance weight, thus avoiding unnecessary damages to device repairing personnel, motors and the decelerator.

Description

The lift non-return device

Technical field

The utility model relates to a kind of non-return device, relates in particular to the non-return device that a kind of main shaft of hoister is rotated usefulness.

Background technique

Lift is when normal work, the hopper of one side has filled up material, opposite side is empty hopper, the weight of both sides is uneven horizontal, if in maintenance or during the lift proper functioning, have a power failure suddenly, when changing motor reducer, because what its both sides were born varies in weight, one side of having filled up material stresses than another himself, under the effect of gravity, slide fast downwards, this has brought potential safety hazard for the overhaul of the equipments personnel, because it has caused unnecessary damage for speed reducer, motor to lower slider fast, has increased use and maintenance cost.

The model utility content

Technical problem to be solved in the utility model provides a kind of lift non-return device, during with solution lift proper functioning, when power failure suddenly or replacing motor reducer, the lift hopper glides fast because of weight is uneven, and overhaul of the equipments personnel and motor, speed reducer are brought the problem of unnecessary injury.

For solving the problems of the technologies described above, the technical solution of the utility model is: the lift non-return device, comprise the lift transmission shaft, and it also comprises the ratchet that is fixedly mounted on described transmission shaft one end, the ratchet that matches with described ratchet, the fixed base of fixing described ratchet.

As a kind of improvement, described transmission shaft is a main chain wheel.

As a kind of further improvement, described fixed base is provided with the protective housing of the described ratchet of protection, ratchet.

Owing to adopted technique scheme, the lift non-return device, comprise the lift transmission shaft, it also comprises the ratchet that is fixedly mounted on described transmission shaft one end, the ratchet that matches with described ratchet, the fixed base of fixing described ratchet, because the effect of described ratchet, ratchet is to rotate to a direction, so when the lift proper functioning, when power failure suddenly or replacing motor reducer, the lift hopper can not glide fast because of weight is uneven, thereby can not bring unnecessary injury to overhaul of the equipments personnel and motor, speed reducer yet.

Fig. 1 is the utility model embodiment's a structural representation;

Fig. 2 is Fig. 1 plan view;

Fig. 3 is the utility model embodiment's rigging position figure.

Embodiment

As Fig. 1, Fig. 2 and shown in Figure 3, the lift non-return device, comprise lift transmission shaft 1, it also comprises the ratchet 2 that is fixedly mounted on described transmission shaft 1 one ends, the ratchet 3 that matches with described ratchet 2, the fixed base 4 of fixing described ratchet 3, described fixed base 4 is provided with the protective housing 5 of the described ratchet 2 of protection, ratchet 3, preventing that foreign object from entering in described ratchet 2 and the described ratchet 3, prevent that also described ratchet 2, ratchet 3 from hurting operator, is a safety guard.Described transmission shaft 1 is a main chain wheel, promptly an end adds and grows to outside the lift housing, described ratchet 2 is fixedly mounted on the lengthening end of described transmission shaft 1, and described fixed base 4 is fixed on the housing in the described lift outside, and total just seems compact reasonable like this.Described ratchet 2 and ratchet with matching 3 make described lift transmission shaft 1 rotate to a direction together, and historical facts or anecdotes has showed the check purpose of lift.

Claims

1. lift non-return device, comprise lift transmission shaft (1), it is characterized in that: it also comprises the ratchet (2) that is fixedly mounted on described transmission shaft (1) one end, and the ratchet (3) that matches with described ratchet (2) is installed the fixed base (4) of described ratchet (3).

2. lift non-return device as claimed in claim 1 is characterized in that: described transmission shaft (1) is a main chain wheel.

3. lift non-return device as claimed in claim 1 is characterized in that: described fixed base (4) is provided with the protective housing (5) of protection described ratchet (2), ratchet (3).
