Building materials conveyer

Technical Field

The invention relates to the technical field of buildings, in particular to a building material conveying device.

Background

The building is a general term of buildings and structures, and is an artificial environment created by people by using the grasped material technical means and applying certain scientific laws, geomantic omen concepts and aesthetic rules to meet the needs of social life. The building is made of clay, bricks, tiles, stones and wood for people; (reinforced concrete and section bars are used recently) and other building materials, such as houses, bridges, plants, gymnasiums, cave dwellings, water towers, temples and the like. In a broad sense, landscapes and gardens are also part of buildings.

When building materials are to be installed inside, they are generally used for building materials such as wall tiles, floor tiles, and glass. In transporting these building materials, box-type freight vehicles are generally used for transportation; in loading the goods, the building materials are usually packed and then distributed in the transport box in order from the front end of the transport box, and in unloading, the building materials are required to be gradually unloaded from the rear end of the transport box. Since the unloading of the building materials cannot be directly dumped like the unloading of the gravels, the loading and unloading must be completed manually, so that the efficiency is reduced and human resources are wasted.

Disclosure of Invention

The invention aims to provide a building material conveying device, which is used for improving the loading and unloading efficiency of building materials.

In order to achieve the above purpose, the basic scheme of the invention is as follows:

the building material conveying device comprises a conveying box and a frame, the tail part of the conveying box is hinged to the tail end of the frame, and the front end of the frame is provided with a hydraulic oil cylinder capable of pushing the front end of the conveying box to rise; the conveying box is internally provided with a cargo carrying unit, the cargo carrying unit comprises a first chain and a second chain, the first chain comprises a horizontal section and an upwarping section close to the tail part of the conveying box, the second chain and the horizontal section of the first chain are oppositely arranged, the first chain is fixedly connected with the conveying box, the second chain is arranged above the first chain, and the second chain is annular; a plurality of load chain wheels are arranged between the first chain and the second chain, the load chain wheels are meshed with the first chain and the second chain, a load bearing shaft is fixed in the middle of each load chain wheel, and the load bearing shafts are connected with the transport boxes in a sliding manner; the both ends of second chain are equipped with respectively and rotate first sprocket and the second sprocket of being connected with the transport case, and the winding of second chain is on first sprocket and second sprocket, and driving motor is connected to first sprocket, and pneumatic brake is connected to the second sprocket, the below of first chain upwarp section is equipped with the depression bar of being connected with pneumatic brake.

The principle of this scheme building materials conveyer lies in:

the building materials such as the floor tiles are packaged into bundles, and the bundles of the floor tiles are hung on a bearing shaft to transport the floor tiles. When unloading, the front end of the transport box is lifted by the hydraulic oil cylinder, so that the transport box is in an inclined state; the bundle-shaped floor tiles will be in a vertical state under the action of gravity, and the horizontal section of the first chain will be in an inclined state. The bearing shaft is subjected to the downward gravity of the floor tiles, so that the load chain wheel rolls downwards along the first chain, and the load chain wheel drives the second chain to rotate; since the second chain is wound around the first and second sprockets, the first and second sprockets will also rotate. The second chain wheel is connected with a pneumatic brake, and the pneumatic brake and a brake disc of the automobile have the same function, namely the pneumatic brake can form resistance to the rotation of the second chain wheel. The pneumatic brake has an initial braking force to the second chain wheel, and when the transport case is in an inclined state, under the action of the initial braking force, the brick inevitably pulls the load chain wheel to slide down rapidly on the first chain.

When the transport case is in an inclined state, the horizontal section of the first chain is inclined, and the upwarp section of the first chain is horizontal. As the load sprocket gradually slides in the horizontal section of the first chain, the load sprocket will gradually enter the upturned section of the first chain. Because the lower part of the upwarping section of the first chain is provided with the pressure lever, when the floor tiles are hung on the bearing shaft, the load chain wheel bears the great weight, so that the bearing shaft has larger inertia, and the load chain wheel continuously slides on the upwarping section, so the bearing shaft presses the pressure lever downwards; thereby the air feed pressure of pneumatic brake increases, and pneumatic brake has the braking action to the second sprocket this moment, and the second sprocket will be unable to rotate promptly. Therefore, the second chain will not rotate, and the first chain and the second chain will be in a relatively static state, so that the load chain wheel will be stuck between the first chain and the second chain, and the floor tile will not slide down continuously. At this time, the floor tiles on the upwarping section of the first chain can be detached from the bearing shaft, the bearing shaft does not press the pressure lever any more, the load chain wheel on the horizontal section of the first chain continues to roll downwards, and the load chain wheel on the upwarping section can be moved to the end part.

When loading goods, start driving motor, then driving motor can provide the moment of torsion to first sprocket, and first sprocket drives the second chain and rotates, and the lower part of second chain upwards rotates, and the load sprocket that can the driven is located between first chain and the second chain upwards rolls. The bundled floor tiles are gradually hung on the load chain wheel on the first chain, and the floor tiles are pushed to the front end of the transport case, so that the load chain wheel can be driven to roll forwards. When the load chain wheel rolls between the first chain and the second chain, the second chain can drive the load chain wheel to roll upwards, and then the floor tiles can be put into the transport box.

The beneficial effect that this scheme produced is:

the upwarp section of the first chain is positioned at the tail end of the transport box, so that unloading and loading of cargoes can be carried out at the tail end of the transport box; the goods at the front end of the transport box can automatically slide to the tail end of the transport box under the action of gravity, so that the goods can be unloaded conveniently; and can promote the goods to the front end of transport case again through driving motor, it is also more convenient to load the goods.

The second chain and the pneumatic brake are arranged, so that resistance can be formed when the load chain wheel rolls downwards, and the load chain wheel is prevented from rolling too fast to cause damage caused by mutual collision of cargoes; in addition, through load chain wheel extrusion depression bar, can make pneumatic brake's braking force increase to make the unable rotation of second chain, then can die the load chain wheel card between first chain and the second chain, then when unloading, the goods will not slide down, thereby can improve the security.

The first preferred scheme is as follows: as a further optimization of the basic scheme, two opposite slideways are arranged on the side wall of the transport case, and two ends of the bearing shaft are respectively inserted into one of the slideways; the slide way can avoid the load chain wheel to be separated from the first chain, and can also avoid the load bearing shaft from being inclined.

The preferred scheme II is as follows: as a further optimization of the first preferred scheme, a lantern ring rotatably connected with the bearing shaft is sleeved on the bearing shaft, and a hook is fixed on the lantern ring. The floor tiles are hung on the bearing shafts, so that the hooks are arranged to facilitate loading and unloading of goods; the collar is rotatably connected to the bearing shaft as the tile is held in a vertical position relative to the floor.

The preferable scheme is three: as a further optimization of the second preferred scheme, the lantern ring is rotatably connected with the bearing shaft through a bearing; thereby reducing wear between the collar and the bearing shaft.

The preferable scheme is four: as a further optimization of the third preferred scheme, a plurality of cargo units are arranged, and the cargo units are parallel to each other; thereby increasing the utilization of the inner space of the transport box.
