Description

The utility model relates to the field of ensuring the safety of loading and unloading operations when moving goods in construction and ritual facilities, namely, to the design of a trolley for transporting stone slabs to the place of installation and / or installation.

Known two-wheeled trolley Abaco for manual movement of stone slabs. The trolley consists of a frame, two handles for transportation and maneuvering, two pneumatic tires. Stone slabs for transportation are laid on the frame in a horizontal plane. With the help of handles and two wheels, the worker moves the stone slab to the specified place (see the catalog of goods on the website of the official store in the Russian Federation of the manufacturer Ausavina / Abaco: https://ausavina.ru/telejki-i-stoly/dvuhkolesnaya-telejka-abaco-gruz -750-kg).

A wheelbarrow is known (see patent RU 100043 U1, B62B 1/18, publ. 12/10/2010), containing a body with an emphasis mounted on a frame with handles, a movement unit connected to the frame, containing a wheel, characterized in that the body is made in the form base with boards pivotally connected to it, detachably connected to each other, the displacement unit is made removable, and the frame is made in the form of longitudinal rods fixed on the body base by means of clamps with the possibility of changing their position relative to each other.

The closest technical solution is a trolley with an SSD-35 bar for manual movement of stone slabs (AUSAVINA/ABACO). The trolley consists of a frame, two pneumatic tires and an upper support on the bar. The upper support on the bar is attached to the plate, after fixing it, the trolley can be moved. The trolley frame has a rubber coating to protect the plate from scratches and chips. 2 pneumatic tires reduce vibration when moving (see the product catalog on the website of the supplier of professional tools for processing natural and artificial stone ALMIR: https://almir.com/market/transportirovka_skladirovanie_i_drugie_prisposobleniya_aksessuary/telezhki_i_aobraznye_ramy/telezhka_so_shtangoj_ssd-35_dlya_ruchnogo_peremeweniya_ kamennyh_plit_ausavina_abaco_ausavina_abako/).

However, a trolley with a SSD-35 bar for manual movement of stone slabs, although it has a small dimension between the wheels, but in narrow places due to two wheels and their sequential arrangement, it does not always pass in terms of its dimensions and maneuvering characteristics. In this case, practice shows that in order to complete the work order, workers have to transfer facade tiles and tombstones to the installation site manually. Sometimes it turns out to do it together, and in especially narrow places one worker has to carry the load. Exceeding the maximum allowable loads for carrying weights manually leads to a number of disorders in the lumbar region of workers. As a result of these causes, inflammatory processes and degenerative changes in the vertebrae and muscles develop, a feeling of enslavement and pain arises, sometimes so strong that a person is forced to stay in bed.

At present, it is widespread to perform construction work on facing the facades of buildings and installing tombstones for monuments on the grave, made of natural stone (marble or granite). This is due to a number of properties of the material: aesthetic properties, durability (the material withstands severe loads with little or no damage, does not absorb moisture and is not subject to destruction under temperature loads), as well as the possibility of processing natural stone (applying high-quality drawings, photographs, inscriptions to this material).

There are a lot of sizes and shapes of facing materials and tombstones on the market today.

The most common sizes of tombstones: 80×40 cm; 100×50 cm; 100×60 cm; 120×60 cm; the thickness of the plates is 8-10 cm. The weight of the most common tombstones ranges from 120 to 250 kg.

The size of marble and granite tiles for facing the facade of the building, which are used for work: 30 × 30 cm, 50 × 30 cm, 60 × 40 cm, 40 × 40 cm, 30 × 30 cm. The average thickness is about 4 cm (from 2 to 6 cm depending on the type of product). Weight reaches up to 40-60 kg.

In accordance with paragraph 34 of the Rules for labor protection during loading and unloading operations and placement of goods, approved by Order of the Ministry of Labor of Russia dated October 28, 2020 No. 753n, loading and unloading operations are allowed subject to the maximum allowable norms for one-time lifting of weights (without moving): men - not over 50 kg; women - no more than 15 kg. According to table 2 of Appendix No. 20 "Methods for conducting a special assessment of working conditions" approved by Order of the Ministry of Labor of Russia dated January 24, 2014 No. 33n, permissible working conditions (class 2 working conditions) for men include: lifting and moving (one-time) gravity when alternating with another work (up to 2 times per hour) of loads weighing up to 30 kg or Lifting and moving gravity constantly during the working day (shift) (more than 2 times per hour) loads weighing up to 15 kg.

Thus, large-sized tiles for facing the facades of buildings, as well as stone tombstones in the ritual economy, must be moved using mechanization.

Currently, the issues of ensuring safety when lifting and moving heavy loads during construction work and work in the ritual economy, which are performed in cramped conditions, are relevant.

When facing the facades of buildings in large cities, it is not uncommon to work in cramped conditions, so there is a need for mechanization.

In today's urbanized world with a high population density and development, the land intended for the burial of the deceased in urban cemeteries is shrinking. The cemeteries are full, and in most cases there is no way to increase their area. At present, due to the dense burial of the deceased in city cemeteries, the passages between the graves have become very narrow, 40-50 cm.

The technical result of the proposed utility model is to increase maneuverability while reducing the dimensions of the device.

This technical solution can be implemented by installing one wheel, which will increase maneuverability compared to two wheels installed in series. And also installing this wheel under the frame itself, and not on the side of the frame - this will reduce the width of the cart. In order for the trolley to be controlled and not fall, the handles are parallel to the wheel (the plane of the plate). Thus, this trolley can be used to transport stone slabs in the narrowest places.

The difference lies in the following: the proposed trolley has one wheel, which is located under the frame. Handles for movement and balance are located parallel to the frame.

The essence of the utility model lies in the fact that a trolley for transporting stone slabs, including a frame made of a metal rectangular profile with stops located along the edges of the frame and an axle with handles at the ends fixedly fixed to the frame, and at the bottom a base, from below which is parallel to the handles, a wheel is installed to move the trolley.

The essence of the utility model is illustrated by the drawing, which shows a general view of the trolley.

The trolley for transporting stone slabs to the place of installation or installation consists of a frame made of a metal rectangular profile 1, along the edges of the frame there are two stops for fixing the slab from slipping 3. An axle 4 with handles 5 on both sides at the ends is fixed on the frame from above for moving and balancing the trolley with the stove. At the bottom of the frame 1, a base 2 is fixedly fixed for the installation of stone slabs. To move the trolley, a wheel 6 is fixed from below the base 2 and parallel to the handles 5.

The device works as follows.

The trolley is intended for use by two workers. Before installing the slab on the trolley, one of the workers holds the trolley, the other installs the slab on the trolley. The plate is installed on the base 2 within the boundaries of the stops 3, while the plate should not be raised very high - this is the height of the wheel (20-30 cm). After installing the plate on the trolley, two workers transport it, holding the handles 5 on the axis 4 to the installation site. Due to the fact that the wheel 6 is installed along the base 2, parallel to the handles 5, the trolley passes through any narrow places. The top of the trolley base 2 has a solid rubber coating to protect the plate from scratches and chips.

Removing the plate from the trolley is carried out in the reverse order.
