Abstract
The present invention relates to a kind of buffer unit of hoist engine, which is arranged on the main shaft of hoist engine, it is characterised in that：Including anchor ear, asbestos yarn and fastening seat；By being provided with the hooping structure of asbestos yarn on hoist engine in the present invention, during the rotation of hoist engine shaft, anchor ear follows hoist engine to rotate together, drive rod is driven to drive the movement of fastening pawl by being powered to electromagnet when needing to brake, so that fastening pawl limits the rotation of anchor ear close to the outside of anchor ear and then with the cooperation of the fastening block of anchor ear outer wall, and the shaft of hoist engine can become sliding friction from static friction on asbestos yarn due to inertia, quickly hoist engine can be braked, reduce the installation space of brake apparatus and braking time is short.
Description
Technical field
The present invention relates to hoist engine brake field more particularly to a kind of buffer units of hoist engine.
Background technique
Hoist engine, with reel winding wire ropes or chain lifting or the light and small heavy-duty hoisting equipment of traction, also known as winch.
Hoist engine can with vertical-lift, horizontally or diagonally drag and draw weight.Hoist engine is divided into manual hoist and two kinds of electrical hoist.It is existing
Based on electrical hoist.It can be used alone, lifting can also be made, built the road and the building block in the machinery such as mine hoisting, because
It is easy to operate, wiring amount is big, dislocation is convenient and is widely applied.Mainly apply to building, hydraulic engineering, forestry, mine, harbour etc.
Material lifting or flat drag.
But general hoist engine braking time is long, it is difficult to brake, arrestment mechanism complexity occupies big quantity space.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of buffer unit of hoist engine, general winch brake device
It is bulky, the problem of braking effect time length.
In order to solve the above technical problems, the technical scheme is that：A kind of buffer unit of hoist engine, the buffer unit
It is arranged on the main shaft of hoist engine, innovative point is：Including anchor ear, asbestos yarn and fastening seat；
The rounded structure of anchor ear, and anchor ear is bolted by a pair semicircle anchor ear arranged symmetrically and is formed, described armful
The screw hole with asbestos band connection is evenly distributed on hoop；The both ends of the semicircle anchor ear, which are provided with, is bolted otic placode, institute
State the fastening block that protrusion is provided on the middle position outer wall of semicircle anchor ear；
The asbestos yarn is tightly attached to the inner wall of anchor ear, and asbestos yarn is locked on the screw hole on anchor ear by screw；
The side of anchor ear is arranged in the fastening seat, and the fastening seat includes fastening pawl, pedestal, electromagnet and drive rod；Institute
It states fastening pawl to be of an L-shaped structure, the corner of fastening pawl is hinged on pedestal, the fastening on one end and anchor ear of fastening pawl
Block cooperation, the other end of fastening pawl are connected with one end of drive rod, the output end of the electromagnet and the other end of drive rod
It is connected, electromagnet can drive drive rod to drive fastening pawl close to anchor ear after powered up, so that fastening pawl stops anchor ear rotation.
Further, elastomeric pad is provided between the bolt connection of the semicircle anchor ear.
Further, the bolt connected on otic placode that is bolted can carry out elastic adjusting.
The advantage of the invention is that：
1）By being provided with the hooping structure of asbestos yarn on hoist engine in the present invention, in the process of hoist engine shaft rotation
In, anchor ear follows hoist engine to rotate together, and drives drive rod to drive fastening pawl by being powered to electromagnet when needing to brake
Movement, so that fastening pawl limits the rotation of anchor ear close to the outside of anchor ear and then with the cooperation of the fastening block of anchor ear outer wall, and
The shaft of hoist engine, can be quickly to hoist engine system since inertia can become sliding friction from static friction on asbestos yarn
It is dynamic, reduce the installation space of brake apparatus and braking time is short.
Detailed description of the invention
The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.
Fig. 1 is a kind of buffer device structure of hoist engine of the invention.
Specific embodiment
The following examples can make professional and technical personnel that the present invention be more fully understood, but therefore not send out this
It is bright to be limited among the embodiment described range.
A kind of buffer unit of hoist engine as shown in Figure 1, the buffer unit are arranged on the main shaft of hoist engine, including embrace
Hoop 1, asbestos yarn 2 and fastening seat 3.
The rounded structure of anchor ear 1, and anchor ear 1 is bolted by a pair semicircle anchor ear arranged symmetrically and is formed, it is described
The screw hole connecting with asbestos yarn 2 is evenly distributed on anchor ear 1；The both ends of the semicircle anchor ear, which are provided with, is bolted otic placode
11, the fastening block 12 of protrusion is provided on the middle position outer wall of the semicircle anchor ear.
Asbestos yarn 2 is tightly attached to the inner wall of anchor ear 1, and asbestos yarn 2 is locked on the screw hole on anchor ear 1 by screw.
The side of anchor ear 1 is arranged in fastening seat 3, and the fastening seat 3 includes fastening pawl 31, pedestal 32,33 and of electromagnet
Drive rod 34；The fastening pawl 31 is of an L-shaped structure, and the corner of fastening pawl 31 is hinged on pedestal 32, fastening pawl 31
One end and anchor ear 1 on fastening block 12 cooperate, the other end of fastening pawl 31 is connected with one end of drive rod 34, the electromagnetism
The output end of iron 33 is connected with the other end of drive rod 34, and electromagnet 33 can drive drive rod 34 to drive fastening pawl after powered up
31 close to anchor ear 1, so that fastening pawl 31 stops anchor ear 1 and rotates.
Elastomeric pad is provided between the bolt connection 11 of semicircle anchor ear.
Elastic adjusting can be carried out by being bolted the bolt connected on otic placode 11.
It should be understood by those skilled in the art that the present invention is not limited to the above embodiments, above-described embodiment and explanation
It is merely illustrated the principles of the invention described in book, without departing from the spirit and scope of the present invention, the present invention also has
