Description

Chain breakage preventing structure of elevator

Technical Field

The utility model relates to a lifting machine, in particular to chain breakage preventing structure of lifting machine.

Background

When the lifting machine is used for the transportation of cement plant, because soil class self is heavier, when the lifting machine stopped, the action wheel that the motor drove stopped, but because inertia, can carry out a pull to the chain from the driving wheel, so the chain is easy to be cracked.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a chain breakage structure is prevented to lifting machine to the easy fracture problem of chain that provides in solving above-mentioned background art.

In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a chain breakage structure is prevented to lifting machine, which comprises a bracket, the pivot is installed to support upper portion and lower part, the symmetry is equipped with the sprocket in the pivot, there is the chain on the sprocket, install the link joint between the chain about, be fixed with the baffle on the link joint, a serial communication port, there is driven sprocket in the outside of support upper portion one side sprocket, driven sprocket and drive sprocket pass through the chain and connect, drive sprocket connects on motor spindle, the motor is fixed on the support, the drive sprocket outside articulates there is the pawl, there is the ratchet in the driven sprocket outside, ratchet and pawl cooperation, the pawl is spacing through spacing spring, spacing spring passes through the bolt and installs on drive.

Further, the middle part of the baffle is arc-shaped.

Furthermore, tooth grooves are uniformly distributed on the ratchet wheel along the circumference, and ratchets are fixed in the tooth grooves.

Compared with the prior art, the beneficial effects of the utility model are that: the chain breakage caused by inertia when the hoister stops moving is prevented; the pawl is more stable than the traditional spring form by adopting the form of the fixed limit block.

In fig. 1 to 2, 1, a bracket, 2, a rotating shaft, 3, a chain wheel, 4, a chain, 5, a chain plate, 6, a baffle plate, 7, a driven chain wheel, 8, a driving chain wheel, 9, a motor, 10, a pawl, 11, a ratchet wheel, 11.1, a tooth space, 11.2 ratchet teeth, 12 and a limiting spring.

Detailed Description

The technology in the embodiment of the present invention will be described below with reference to the accompanying drawings in the embodiment of the present invention

The embodiments are described in detail, clearly, and not in their entirety, it is to be understood that the embodiments described are only some of the embodiments of the present invention and are not to be taken as a complete description. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

In the description of the present invention, it should be understood that the indicated orientation or positional relationship is based on the orientation or positional relationship shown in the drawings, and is only for convenience of description and simplification of description, and does not indicate or imply that the indicated device or element must have a particular orientation, be constructed and operated in a particular orientation, and thus should not be construed as limiting the present invention.

In fig. 1 to 3, a chain breakage preventing structure of a hoist, including support 1, pivot 2 is installed to support 1 upper portion and lower part, the symmetry is equipped with sprocket 3 on pivot 2, there is chain 4 on sprocket 3, install link joint 5 between the left and right sides chain 4, be fixed with baffle 6 on the link joint 5, a serial communication port, there is driven sprocket 7 outside one side sprocket 4 on support 1 upper portion, driven sprocket 7 and drive sprocket 8 pass through chain 4 and connect, drive sprocket 8 connects on the main shaft of motor 9, motor 9 is fixed on support 1, the articulated pawl 10 in the drive sprocket 8 outside has, there is ratchet 11 in the driven sprocket 7 outside, ratchet 11 and pawl 10 cooperate, pawl 10 is spacing through spacing spring 12, spacing spring 12 passes through the bolt and installs on drive sprocket 8.

Further, the middle part of the baffle 6 is arc-shaped.

Furthermore, tooth grooves 11.1 are evenly distributed on the ratchet wheel 11 along the circumference, and the ratchets 11.2 are fixed in the tooth grooves 11.1 through bolts.

When power is cut off or shutdown is needed, the cement bag on the right side of the hoister has a downward force to rotate the driven sprocket 7, the driving sprocket 8 is stopped, the chain 4 is pulled at the moment, the pawl 10 can just prevent the driven sprocket 7 from rotating, and the middle part of the baffle 6 is arc-shaped to prevent the cement bag from falling off due to vibration when power is cut off or shutdown is needed; the arrangement of the ratchet 11.2 is convenient for replacement.

In the present invention, unless otherwise explicitly specified or limited, for example, it may be fixedly connected, detachably connected, or integrated; can be mechanically or electrically connected; they may be directly connected or indirectly connected through an intermediate medium, and may be connected through the inside of two elements or in an interaction relationship between two elements, unless otherwise specifically defined, and the specific meaning of the above terms in the present invention will be understood by those skilled in the art according to specific situations.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
