Description

Belt unfolding frame

Technical Field

The utility model belongs to the technical field of the mine instrument, concretely relates to belt expansion frame.

Background

When the belt is replaced by the belt conveyer, a new belt to be replaced needs to be supported at the head or the tail by the frame and unfolded, one end of the new belt is connected to an old belt to be replaced in subsequent operation, the height of the existing frame for placing the new belt is not adjustable, the new belt is frequently matched with the height of the head or the tail in a temporary heightening mode during actual use, and the situation that the belt is easily stressed in an unbalanced mode to cause toppling is caused when the belt is pulled.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a belt expansion frame has solved current belt expansion frame height and can not be adjusted and lead to easily empting the problem.

The utility model adopts the technical proposal that: the belt unfolding frame comprises two tripods arranged at intervals side by side, wherein a longitudinal supporting cylinder is arranged on the top end of each tripod, a lifting column extending upwards from the top end is coaxially arranged in each supporting cylinder, a supporting tile is fixed on the top end of each lifting column, a supporting roller cylinder is jointly erected above the two supporting tiles, a level meter is fixed at the bottom end of the side wall of the supporting roller cylinder, and a jack is fixed in each tripod, extends into the supporting cylinder from the top end of each tripod and supports the bottom end of each lifting column.

The utility model is also characterized in that,

the top end of the lifting column is fixedly sleeved with a limiting ring positioned above the top end of the supporting cylinder.

A bottom plate is jointly fixed below the three supporting points at the bottom end of the tripod, and the jack is fixed on the bottom plate.

Two moving bars are oppositely fixed on two sides of the tripod.

The roller supporting cylinder is coaxially sleeved with an extension roller with two ends extending outwards.

The utility model has the advantages that: the utility model discloses a belt expansion frame is through setting up the lift post in the tripod to adjust the lift post and then adjust the height of bearing roller section of thick bamboo through the jack, combine the indicative function of spirit level to make the bearing roller section of thick bamboo remain the level all the time, make the belt of placing and expanding on the bearing roller section of thick bamboo can with the high phase-match of belt conveyor aircraft nose or tail, thereby the atress is more stable when carrying out the belt and changing the operation, is difficult for empting.

Fig. 1 is a schematic structural view of the belt unwinding stand of the present invention.

In the figure, 1, a tripod, 2, a supporting cylinder, 3, a lifting column, 4, a supporting tile, 5, a supporting roller barrel, 6, a level meter, 7, a jack, 8, a limiting ring, 9, a bottom plate, 10, a moving lever and 11, an extension roller.

Detailed Description

The present invention will be described in detail with reference to the accompanying drawings and specific embodiments.

The utility model provides a belt expansion frame, as shown in figure 1, including two tripods 1 that set up at the interval side by side, the equal mount in top of every tripod 1 is equipped with fore-and-aft supporting cylinder 2, and equal coaxial lifting column 3 that upwards stretches out in the top that is provided with in every supporting cylinder 2, the fixed cover in top of lifting column 3 is equipped with the spacing collar 8 that is located supporting cylinder 2 top, and 8 direct cards of spacing collar are in 2 top tops of supporting cylinder, and the minimum height of having guaranteed lifting column 3 is unlikely to cross lowly. The top of every lift post 3 all is fixed with the support tile 4, and the top of two support tiles 4 has erect the support roller section of thick bamboo 5 jointly, and the coaxial registrate has both ends all outwards to stretch out extension roller 11 in the support roller section of thick bamboo 5, improves the suitability to different width belts. The lateral wall bottom mounting of bearing roller 5 has spirit level 6, and the three fulcrum below in bottom of every tripod 1 is fixed with bottom plate 9 jointly and improves the stability of tripod 1 landing leg, all is fixed with the top on every bottom plate 9 and stretches into bearing cylinder 2 and supports to the jack 7 of 3 bottoms of lifting column. In order to facilitate the movement of the belt stretcher, two moving bars 10 can be fixed on two sides of the tripod 1, and two persons can lift the two moving bars 10 to move the tripod 1.

When the belt replacing device is used, a new belt to be replaced is unfolded and placed on the supporting roller 5, when the width is insufficient, the extension roller 11 is added to ensure that the belt is fully unfolded and the width direction can be effectively supported, the jack 7 on one base plate 9 is operated to enable the top end of the jack 7 to extend into the supporting cylinder 2 and jack the lifting column 3, the lifting column 3 drives the supporting tile 4 and one end of the supporting roller 5 on the supporting tile to ascend after ascending, then the other jack 7 is operated in the same mode, the single ascending amplitude of each jack 7 is not too high to prevent the supporting roller 5 from being too inclined, the jacks 7 can be simultaneously operated in the two tripods 1 by two operators, the ascending amplitudes of the two jacks 7 are adjusted at any time through the horizontal indication of the level gauge 6 in the operation process, the jacks 7 are stopped to be operated when the height of the supporting roller 5 is matched with the height of a head or a tail of a belt conveyor, and subsequent belt replacing operation is carried out. After the operation is finished, the roller supporting barrel 5 is taken down from the supporting tile 4, and two persons lift up the two moving bars 10 to move the tripod 1, so that the convenience of the belt unfolding frame is improved, and the applicability to different terrain environments is improved.

In this way, the utility model discloses a belt expansion frame is through setting up lifting column 3 in tripod 1 to adjust lifting column 3 and then adjust the height of bearing roller 5 through jack 7, combine the indicative function of spirit level 6 to make bearing roller 5 remain the level throughout, make the belt of placing and expanding on bearing roller 5 can with belt conveyor aircraft nose or tail height phase-match, thereby the atress is more stable when carrying out the belt change operation, is difficult for empting.
