A equipment work is safer, reliable.
In order to solve the above-mentioned technical problem, the technical solution of the utility model are as follows:
One kind pulling a shield, including cover body, is provided on the cover body for pulling the center hole that cylinder passes through, the cover
The arc top surface of ontology is exported equipped with wirerope, and the oblique upper of arc top surface, the wirerope is arranged in the wirerope outlet
The corresponding central angle of the arc length of outlet is 45~90 °.
As a preferred embodiment of the present invention, the corresponding central angle of arc length of the wirerope outlet is 60 °.
As a preferred embodiment of the present invention, the wirerope outlet is rectangular aperture, the size of the rectangular aperture
Greater than the hunting range of wirerope.
As a preferred embodiment of the present invention, the material of the cover body is stainless steel or aluminium.
Further, the plate thickness that the cover body uses is 3~5cm.
As a preferred embodiment of the present invention, the cover body is by support frame and the end plate group for being located at support frame two sides
At two end plates are oppositely arranged, and every end plate is equipped with the center hole, and support frame as described above includes arc top plate and two bearings
Vertical plate, the two bearing vertical plate tops being oppositely arranged connect the both ends of the arc top plate, the bottom end of each bearing vertical plate to
It is bent with support outside, the cover body is fixed on the table by the support of two sides, and the arc top surface is located at the circular arc
The surface of top plate.
Further, the rest base is equipped with cushion.
In conclusion due to the adoption of the above technical scheme, the beneficial effects of the utility model are:
The utility model shield stops it to be wrapped on speed reducer output shaft in time when wirerope falls off, structure
Simply, and installation is extremely simple, and after pulling cylinder and installing with speed reducer, the center hole of shield need to will only be pulled to cylinder socket,
It is concordant to pull the outer two end plates of a both ends and shield, not only plays good protective action to pulling cylinder, also acts as dust-proof effect, prolong
The long service life for pulling cylinder and concrete mixer equipment.

Specific embodiment
Specific embodiment of the present utility model is described further with reference to the accompanying drawing.It should be noted that
The explanation of these embodiments is used to help to understand the utility model, but does not constitute the restriction to the utility model.This
Outside, technical characteristic involved in the various embodiments of the present invention described below is as long as they do not conflict with each other
It can be combined with each other.
Referring to Fig.1, one kind pulling a shield, including cover body 10, is provided on the cover body 10 and passes through for pulling cylinder 100
Center hole 1, the arc top surface of the cover body 10 is equipped with wirerope outlet 3, and the wirerope outlet 3 is arranged in arched top
The corresponding central angle 7 of arc length of the oblique upper in face, the wirerope outlet 3 is 45~90 °.Include in main concrete mixer
Bucket and climbing frame are climbed, usual wirerope one end is connected with bucket is climbed, and the other end of wirerope, which is wrapped in, to be pulled on cylinder, current climbing frame and work
Platform forms certain tilt angle, and parallel with climbing frame when steel wire tensioning.
The preferred embodiment of the present embodiment, climbing frame and workbench form 60 ° of tilt angle, and the wirerope goes out 3
The corresponding central angle of arc length is 60 °.
The preferred embodiment of the present embodiment, the wirerope outlet 3 is rectangular aperture, and the size of the rectangular aperture is big
In the hunting range of wirerope.Guarantee that shield will not be collided when wirerope is swung.
The preferred embodiment of the present embodiment, the material of the cover body 10 are stainless steel or aluminium.
Further, the plate thickness that the cover body 10 uses is 3~5cm.
The preferred embodiment of the present embodiment, the cover body 10 is by support frame and is located at 6 groups of end plate of support frame two sides
At two end plates 6 are oppositely arranged, and every end plate 6 is equipped with the center hole 1, and support frame as described above includes arc top plate 2 and two
Vertical plate 4 is supported, two 4 tops of bearing vertical plate being oppositely arranged connect the both ends of the arc top plate 2, each bearing vertical plate 4
Bottom end be bent with support 5 outward, the cover body 10 is fixed on the table by the support 5 of two sides, the arc top surface
