Description

The technical field to which the utility model belongs

The utility model refers to construction equipment that can be used for interior finishing work.

The mobile unit is designed to position, fix and move grinding equipment with dust extraction systems for grinding ceilings.

State of the art

Known mobile machine for complex processing of horizontal and other surfaces (RF patent for invention No. 2198275, class IPC E04F 21/16, publ. 10.02.2003), containing a working body with a drive, mounted on a support rack, drive, lifting and triggering mechanism trolley-mounted.

The disadvantage of the known technical solution is the difficulty of transporting this machine due to its relatively large dimensions and non-separable structure. Due to these design features, the use of this machine is almost impossible in small rooms and / or in rooms with low ceilings, which limits its scope. This mobile device has insufficient mobility due to small wheels, and during the grinding process it is difficult to simultaneously use additional dust-removing equipment, which narrows the functionality of the known machine.

The closest in technical essence and the achieved positive effect to the claimed mechanism - the prototype - is a mobile workstation for systems for grinding walls and ceilings (Internet page: https://images.app.goo.gl/epftRZwFMTxfBtvp9).

Disadvantages of the known device:

- Difficulty of using in small spaces, as well as transportation and storage. The assembled device has a platform size of 670 × 1140 mm, which makes it difficult to use in confined spaces, and in disassembled form 670 × 1400 mm and a set of stand with a handle measuring 1680 × 300 mm, this size of the structure complicates its storage and transportation.

- With significant dimensions, the inability to use in rooms with high ceilings. The maximum working height for this device is 340 cm.

- Lack of easy and precise maneuvering during work. The structure is equipped with a small diameter guide roller, colliding even with a small obstacle, this guide roller cannot overcome it, which greatly complicates the work process. Also, the weight of the entire structure and the equipment attached to it affects maneuverability. The weight of the rig is 31.5 kg, and when loaded it can reach more than 50 kg. This weight, combined with a small idler roller, can significantly reduce flotation.

- Increased complexity and duration of the changeover process. To change the working height or to change the abrasive on the sander, you must unscrew the two lifting bar locks.

There is no system for a convenient and quick change of grinding discs, since they must be replaced quite often (approximately every 15-20 m2 ^{of the} treated surface). It becomes necessary to unscrew the rack mounts. It takes time every time.

- Lack of reliability. The pivot assembly in the structure of the rack has a plastic sleeve that is subject to friction and is short-lived.

- Difficulty ensuring high quality of the grinding process. The presence of a gas lift in the structure implies constant contact of the grinder with the ceiling surface, and creates excessive pressure on the treated surface and there is a risk of damage to the ceiling. In order to exclude spontaneous contact of the grinder with the ceiling surface, each time after completion of work, it becomes necessary to change the height of the rack, for this it is necessary to unscrew two fasteners.

Disclosure of a utility model

The technical result is an improvement in the maneuverability and stability of the installation due to a change in the proportion between the overall dimensions of the installation and the dimensions of the wheels and the implementation of all wheels of the same and sufficiently large diameter (from 200 mm to 250 mm). Also, the claimed design of the installation provides an expansion of the area of use and an increase in the convenience of transportation due to the presence of a sliding bar, which allows you to work with ceilings of more height and then allows you to reduce the dimensions of the installation for moving between rooms through a standard doorway without disassembling it, as well as before transporting it to another an object.

The specified technical result is achieved by the fact that the mobile installation for grinding and dust removal equipment includes a platform on which the front support stand and the rear control stand are fixed, which are connected to each other with the help of the fastening support and connected to the sliding bar, the upper part of the sliding bar is connected to the main support and by means of a pivot assembly with a working rod, on one side equipped with a handle and on the other with a unit for fastening equipment, the platform is mounted on two front wheels and one rear wheel, all wheels having the same diameter.

The mobile installation for grinding and dust removal equipment includes a platform 1 on which a front support post 2 and a rear control post 5 are fixed, which are connected to each other by means of a fastening support 10 and connected to a sliding bar 12, the upper part of the sliding bar 12 is connected to the main support 14 and by means of a hinge assembly 20 with a working rod 16, on one side equipped with a handle 17 and on the other with a unit 19 for attaching equipment, the platform 1 is mounted on two front wheels 3 and one rear wheel 4, all wheels having the same diameter.

The rear control post 5 at the bend point can additionally be equipped with a handle 6 and a clamp 7. The working rod 16 can also be additionally equipped with a clamp 18. The sliding rod 12 can be additionally equipped with a lock 13.

Sliding 12 and 16 working rods can be additionally connected by plate 15 to adjust the angle of inclination.

The handle 17 of the working rod 16 and the handle 6 of the control rack 5 can be made rubberized.

The clamp 7 on the rear control post 5 and the clamp 18 on the working rod 16 are designed for quick disassembly of these elements of the mobile installation, which increases the ease of use of the device.

The maneuverability of the mobile unit has been improved due to a change in the design of platform 1 and equipping the unit with three wheels 3, 4 of the same diameter, the optimal wheel diameter for an installation size of 600 * 1100 mm is 200-250 mm. As a result, the installation overcomes obstacles up to 3 cm in height, which simplified and accelerated the workflow. The lifting capacity has been increased due to the use of industrial wheels with a higher carrying capacity.

The installation maneuverability has been improved due to the reduction in the overall dimensions of the structure. When assembled, it has decreased by 15% and is 600 × 1100 mm, which makes it possible to use the equipment in small rooms from 6 m ² . Disassembled, the overall dimensions of the mobile unit decreased by 45% and amounted to 600 × 950 mm and 35 × 1100 mm for the sliding rod 12, which is much smaller than the prototype and makes it easy to transport the unit even in a passenger car.

The installation is equipped with a sliding bar, which allows surface treatment at a height of 2 to 3.8 meters, which significantly expands the possibilities of its use.

The installation allows you to work with grinding equipment in the most optimal and stable position for it (10 ° -20 ° to the ceiling surface) at high heights.

The weight of the installation also affects the ease of transportation, as a result it is 21.5 kg, and in the equipped state the total weight can be about 40 kg, this has a positive effect on the maneuverability and usability of the mobile installation.

The design of the sliding rod 12 is equipped with a reliable and safe lock 13, which allows you to quickly change the height for processing a surface located at a height of 2 to 3.8 m, as well as fold this rod 12 to a minimum size to move from room to room without removing grinding and dust removal equipment. This helps to speed up the work.

The hinge unit 20, connecting the sliding 12 and the working 16 rods, is equipped with a ball bearing replaceable, which provides an unlimited resource of this structure unit and the smooth running of the working rod 16 during grinding.

A system for quick replacement of grinding discs on the equipment has been implemented, without resorting to disassembling or unscrewing the clamps. For this, if necessary, the lock 13 of the sliding rod 12 and the plate 15 for adjusting the angle of inclination are used. This plate 15 allows you to instantly lower the grinder to an inclined position for access and maintenance.

The design of the installation is designed in such a way that in working condition the grinder comes into contact with the ceiling only when the operator lowers the working bar 16 towards himself and the grinding process begins. When the operator releases the working bar 16 and turns off the equipment, the grinder automatically loses contact with the work surface. This ensures that there is no damage to the surface from the working body of the grinder (regrinding, risks, saws, notches and scratches) of the ceiling.

The work bar 16 is balanced so that when loaded with grinding equipment, the operator only needs to apply minimal force to bring the equipment into contact with the ceiling surface, which ensures fatigue-free and increases labor productivity. This increases the ability to work for a long time.

The design of the unit is designed in such a way that it can be used in combination with various brands of grinding and dust extraction systems. This, in turn, increases its convenience, as there is a wide range of grinding equipment on the market.

The design uses only quick-release clamps, which allows you to assemble and disassemble equipment without the use of additional tools in a short time.

A mobile installation for grinding and dust removal equipment is used as follows.

Assembly:

Install the rear wheel lock 4. Assemble the rear control post 5 using the clamp 7. Raise the front support post 2 to the vertical position and install the rear control post 5 into the elements 8 and 9 of the posts fastening. We assemble the working rod 16 using the clamp 18. Install the assembled rod 16 in the support 10 of the mount, using it as an auxiliary one. We install the sliding rod 12 into the elements 11 for fastening the sliding rod 12. On the platform 1 we install the dust removal equipment. On the working bar 16 we fix the grinding equipment using the fastener 19. We transfer this structure from the support of the fastener 10 to the main support 14. We spread the sliding bar 12 so that from the sanding sole to the ceiling surface remains from 5 to 25 cm, we fix the bar 12 with the lock 13 The device is ready for use.

Grinding:

Using the handle 6 on the control stand 5, the operator rolls the platform 1 around the room in order to move the equipment to the required area. Using the handle 17 on the working rod 16, he moves the grinder left and right and grinds the ceiling. By synchronously controlling these structural units, the sequential grinding of the ceiling is carried out.

Replacing the abrasive disc.

If work is carried out on ceilings with a high height, then first it is necessary to fold the sliding bar 12 to a suitable level by pulling out the lock 13.

In order for the grinder to move from a horizontal position to an inclined position to replace the grinding disc, it is necessary to press the plate 15 from the bottom up to release the blockage, and the working rod 16, together with the grinder, will go down and give access to the working platform of the equipment for replacing the disc.

Implementation example

A prototype of a mobile installation for grinding and dust removal equipment was manufactured. Let's talk about the speed and ease of use on the example of a two-storey house with a total area of 185 m ² , consisting of 10 rooms ranging from 6 to 35 m ² , with a ceiling height of 3 m.

For the purity of the experiment, the work on grinding the ceiling and the whole complex of auxiliary work (power connections, organization of surface lighting and transfer of equipment to the 2nd floor) were performed by one person in 9 hours.

As a result of the work done, it was revealed that thanks to the declared mobile installation, this work was done 3-4 times faster compared to using the same grinding and dust removal system without using the installation. Mobility and security.

When working with this installation, all the attention of a person is riveted to the ceiling, and he does not follow what is in the path of the platform. With this installation, you can be sure that it will overcome most obstacles and at the same time will not damage the ceiling surface due to an unexpected abrupt stop due to the fact that in the design all wheels are made the same and have a sufficiently large diameter (200-250 mm). It has a high cross-country ability, which is necessary at the construction site, since there can often be foreign objects on the floor.
