Description
Technical field
The utility model relates to a kind of polissoirs, use more particularly, to a kind of finisher (trowelling machine) or similar equipment
Transmission switching mechanism device.
Background technique
Polishing concrete has good decorative property, and ground flat degree is good, and easy to clean, maintenance cost is low, and durability is good, the service life
The advantages such as long, are highly suitable for the public arena of high flow of the people.The main processes of polishing concrete construction are grinding, repairing
Gap, solidification and polishing, main construction equipment are polisher lappers.
Currently, polishing grinding equipment is mainly hand-held grinder, working width is generally no greater than 1 meter, leads to its effect
Rate is not high enough, for mega project such as large-scale park, it is necessary to more than ten even tens construction milling apparatus into
Row operation needs to expend a large amount of fund of construction quotient and personnel cost.In order to solve this problem, device manufacturer grinds
The polisher lapper of drive type is had issued, efficiency is higher, but the price of equipment is higher, and purchase is such for construction quotient
Expensive equipment also needs to put into a large amount of fund.
Floor trowelling machine, finisher are also trowelling machine, have drive type, also there is hand-held.Drive type finisher usually has
Two groups of troweling blades, this two groups of troweling blades are respectively by a live spindle driving rotation, and direction of rotation is on the contrary, its working width
Up to 2500mm, the concrete table of high standard workshop, warehouse, parking lot, square, airport and frame type storied house can be widely used for
The warehouse in face, floating, troweling are the important tools of concrete pouring construction.But final surface or phase that finisher is handled out
To relatively rough, if to obtain above-mentioned said decorative finish concrete floor, it is also necessary to subsequent grinding and buffer
Sequence.And the capital equipment of this procedure is planetary plate grinder, this grinder is provided with a big disc spins, installs on deep bid
There are 3 or more shallow bid rotates to another way, is ground in these shallow bids installation top lap and ground face contact
Operation, such grinder price is costly and its working width is approximately less than 1000mm, and heavy construction is come
Say that the requirement of construction quotient is not achieved in its efficiency.
For this demand, there is a solution at present, a flexible connection disk is installed on finisher, then even
It connects and is bonded abrasive disk on disk, carry out grinding and polishing operation using abrasive disk, realize the demand of high-efficient grinding polishing.But it is this
Technique have the defects that it is one very big, due to structure determine this scheme abrasive disk only one around finisher main shaft
A rotation, the uniformity that the terrace surface come is ground is not fully consistent, has still been not up to polishing concrete floor
High standards.For this deficiency, there is another scheme to improve, be exactly in terminal pad each abrasive disk can do free rotation
Turning, therefore when operation, mill is other than having the revolution for following terminal pad, due also to the reaction force of ground grinding contact,
Mill does the rotation of an opposite direction, but this rotation is the rotation of a passive type, encounter ground flat degree it is defective when, often
The revolving speed of a mill is not consistent, though so this scheme has than a upper scheme improves to a certain degree, effect and efficiency are not
It improves a lot.
