Description

Shaft coupling safety device of water pump

Technical Field

The utility model relates to a coupler safety protection device of a water pump.

Background

The main equipment is water pumps which are all transmitted by the rotation of a motor and transmit power to a water supply pump by the motor and a water pump coupler, and the dangerous factor is the coupler, the requirement that the coupler is necessary to cover by turns according to safety specifications is often existed, a safety protective cover is additionally arranged while the water pump is installed, but because the design is unreasonable, the installed protective cover is a half-wrapped type protective cover with four corners inserted or fixed by bolts, so that the safety hidden danger and the maintenance equipment are complicated and other adverse factor defects are caused by daily inspection of post personnel, and because the lower half part of the half-wrapped type coupler is completely exposed outside, the phenomenon that the bolts are loosened or the damping rubber rings are worn out by centrifugal force occurs, the personal injury is caused to the maintenance personnel, meanwhile, because the protective cover is made of iron sheets, whether the bolts of the coupler are loosened or not can not be observed from outside, the protective cover is made of iron sheets, and the safety protective cover is made of a material, Whether the shock attenuation rubber ring is worn and torn, the inspection post personnel all will look over the head to one side deviation from the gap at every turn, very easily take place danger, all will carry out the barring before having water pump outage periodic maintenance and operation again, because the design defect instrument of protection casing can't directly block and carry out the barring, all will dismantle the protection casing at every turn and install again after carrying out the barring, very easily takes place the incident and increased maintainer's intensity of labour simultaneously.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a coupler safety protection device of a water pump, which changes unsafe factors of the original protection device, can not only conveniently protect a motor and a rotating part of the water pump, but also conveniently observe a point inspection worker, completely eradicates unsafe factors when equipment is operated by turning a vehicle, and has convenient installation and simple operation.

In order to solve the technical problems, the utility model adopts the following technical scheme:

the utility model relates to a coupler safety protection device of a water pump, which comprises a protection cover, wherein the protection cover is a circular full-wrapping half-open protection cover, the outer diameter of the protection cover is 50mm-100mm larger than the outer diameter of a coupler, the protection cover is opened at 1/2 of the upper semicircular part and is provided with an articulated piece to form a closable window, and the 1/2 of the lower semicircular part is connected by a bolt.

Further, the hinge component is a hinge.

Further, the protective cover is made of a mesh material.

Further, the mesh material is a metal mesh plate.

Furthermore, the two sides of the protective cover are fixed on the bearing cover of the motor shaft and the bearing box on the inner side of the water pump through bolts to form a fully-enclosed coupler protective cover.

Furthermore, a handle convenient to open is arranged on the window.

Compared with the prior art, the utility model has the beneficial technical effects that:

this shaft coupling protection casing can be completely motor and the whole protection of water pump shaft coupling rotation position, improve post personnel routine maintenance nature of the sight convenience point inspection personnel's observation, utilize netted check iron plate preparation can play easily to observe and the heat dissipation advantage simultaneously, unsafe factor eliminates the potential safety hazard when having stopped equipment operation, need not dismantle the protection casing when equipment needs the barring simultaneously and directly open first window of protection casing and operate, the operation finishes the back the upper cover, it forms whole protection casing again like this to insert locking device, effectual maintainer's intensity of labour that has reduced, and simple to operate, and easy operation.

description of reference numerals: 1. a protective cover; 2. a hinge; 3. a window; 4. a handle.

Detailed Description

As shown in fig. 1 and 2, the coupler safety protection device of the water pump comprises a protection cover 1, wherein the protection cover 1 is a circular full-wrapping half-open protection cover, the outer diameter of the protection cover 1 is larger than the outer diameter of the coupler by 50-100 mm, the protection cover 1 is opened at the 1\2 part of the upper semicircular part and is provided with a hinge 2 to form a closable window 3, and the 1\2 part of the lower semicircular part is connected by bolts. And two sides of the protective cover 1 are fixed on the bearing cover of the motor shaft and the bearing box on the inner side of the water pump through bolts to form a fully-wrapped coupler protective cover. And a handle 4 convenient to open is arranged on the window 3.

Protection casing 1 is made by the netted iron plate that opening width is less than 3mm that adopts 5mm thick in this embodiment, it constitutes the full packet mode shaft coupling protection casing, not only protect the shaft coupling whole but also protect motor and water pump rotary shaft head whole, thorough elimination potential safety hazard, cancelled simultaneously in the past still need weld the footing on the base and insert or bolted connection's installation complicated mode, made things convenient for post staff's point to patrol and examine, through adopting netted material both to make things convenient for maintainer daily observation and make shaft coupling ventilation cooling again.

The above-described embodiments are merely illustrative of the preferred embodiments of the present invention, and do not limit the scope of the present invention, and various modifications and improvements of the technical solutions of the present invention can be made by those skilled in the art without departing from the spirit of the present invention, and the technical solutions of the present invention are within the scope of the present invention defined by the claims.
