Description

A kind of transmission switching mechanism device
Technical field
The present invention relates to a kind of polissoirs, are driven more particularly, to a kind of finisher (trowelling machine) or similar equipment Switching mechanism device.
Background technology
Polishing concrete has good decorative property, and ground flat degree is good, easy to clean, and 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, equipment manufacturers grind The polisher lapper of drive type is had issued, efficiency is higher, but the higher price of equipment, 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 the 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, big disc spins that there are one this grinder settings, is installed on deep bid There are 3 or more shallow bid rotates to another way, contacts and be ground with ground in these shallow bids installation top lap 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, grinding and polishing operation is carried out using abrasive disk, realize the demand of high-efficient grinding polishing.But it is this Technique is there is a prodigious defect, and since structure determines the abrasive disk of this scheme, only there are one surround 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 there are one the revolution of and then terminal pad, due also to the reaction force of ground grinding contact, Mill does the rotation of a negative direction, but this rotation is the rotation of a passive type, encounter ground flat degree it is defective when, often The rotating 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.
Invention content
It is an object of the present invention to overcome the above-mentioned drawbacks of the prior art and provide one kind so that finisher can Carry out the transmission switching mechanism device of efficient, high evenness grinding and polishing operation.
The purpose of the present invention can be achieved through the following technical solutions:A kind of transmission switching mechanism device, device peace In the troweling piece driving spindle of finisher (troweling blade is dismantled), which is characterized in that the device includes and finisher The intermediate connector of main shaft link and several rotating disks, whole device act as synchronous rotary movement with finisher main shaft one, respectively It while rotating disk rotation, revolves round the sun together with whole device, to drive the mill in rotating disk to be ground polishing operation.
The device further includes pedestal, bearing block, sprocket wheel a, reel chain, connecting rod, chain, sprocket wheel b, big sprocket wheel, circle Column sleeve cylinder and rotating disk, the bearing block share N groups, and N >=2, the center line around intermediate connector is uniformly distributed in circumferencial direction, Sprocket wheel a is equipped on each group bearing block, each sprocket wheel a is interlinked by reel chain, each group bearing block pass through connecting rod with it is intermediate Connector links, and the sprocket wheel b is mounted in the one group in N group bearing blocks, and the big sprocket wheel and cylindrical sleeves are successively It is sleeved on the outside of intermediate connector, and three is concentric, but between big sprocket wheel and cylindrical sleeves and intermediate connector and contactless, i.e., greatly Sprocket wheel and cylindrical sleeves empty set in the outside of intermediate connector and ensure with one heart, to pass through chain between the sprocket wheel b and big sprocket wheel Item connection transmission, the spindle nose of each bearing block are mounted on rotating disk, one or more mills are equipped in each rotating disk.
One group of main shaft is longer than the main shaft of other each groups in the N group bearing blocks, which installs sprocket wheel b, Sprocket wheel a is installed lower part.
Each sprocket wheel a is mounted on the main shaft of bearing block, and sprocket wheel a is by being keyed spindle drive torque.
Described connecting rod one end is welded with bearing block, and the other end is welded with intermediate connector.
The device further includes tightener sprocket a, tightener sprocket b, tightener sprocket mounting bracket a and tightener sprocket mounting bracket b, The tightener sprocket a is mounted on tightener sprocket mounting bracket a, and the tightener sprocket b is mounted on tightener sprocket mounting bracket b On, the tightener sprocket mounting bracket a and tightener sprocket mounting bracket b are separately mounted in a connecting rod, the tightener sprocket a For being tensioned reel chain, the tightener sprocket b is used for tension chain.
