Description

Height adjustable middle rack of rubber belt conveyer

The utility model is the accessory of travelling apron.

Travelling apron is big with freight volume, haul distance is long and characteristics such as transportation and be widely used in mine haulage system continuously.What all use at mine and down-hole belt heading at present is the fixed frame type.Because exploiting field, down-hole transportation space is narrow and small, roadway floor is uneven again, and travelling apron is used H type central support always, and it is highly unadjustable.When roadway floor is recessed, just need the workman at things such as H type support underlay wooden unit and stones, its labour intensity is big, and the adjustment time is long, and underbed disorderly moves again easily, so influence normal operation, brings very big difficulty to the user.

The purpose of this utility model is to make support between a kind of adjustable senior middle school of travelling apron, and it is simple in structure, regulates easily, alleviates working strength of workers, has improved the efficient of driving surface.

The utility model by column, heighten column, bolt, nut, spring washer, crossbeam and cushion block and form.Be primarily characterized in that: it increases and heightens column, cushion block, bolt, nut and spring washer on the basis of the central support of original travelling apron, with bolt, nut and spring washer column with heighten column and be linked together.Can make column lifting in heightening the groove of column by the requirement in real work place, and fix, reach the adjustment height of any requirement with bolt, nut.Wherein, column is the channel-section steel body, and two holes are arranged at the bottom, the periphery welding cushion block in the hole, and in the time of can preventing vertical columns like this and heighten column, the column ledge is stuck to be difficult in heightening the ledge of column separately, as shown in Figure 2, is convenient to operation.Heightening column is the channel-section steel body, and he is wideer than column channel-section steel, opens a rectangular slot on the channel-section steel bottom surface, and bolt is moved up and down in groove.Column is fastened in the groove of heightening column, passes the hole of rectangular slot, cushion block and the column bottom of heightening column with bolt, is connected and fixed with spring washer and nut.

Support between the adjustable senior middle school of the travelling apron that combines is put in below the sealing-tape machine adhesive tape, in the time need not heightening, the solid line position of its mode of operation Fig. 1.When needs are heightened, unclamp nut, column drives bolt, nut moves along the rectangular slot of heightening column, and during satisfactory height, fastening nut again is with column with heighten upright bolt and retighten, as Fig. 1 dotted line position.Because height can be regulated arbitrarily, does not limit so heighten highly.

The utility model compared with prior art, it is simple in structure, and is easy to adjust, is not subjected to the condition restriction of driving surface, can adjust the height of central support arbitrarily as the case may be.Safety is good, has kept down-hole travelling apron removable advantage fast again.

Fig. 2 is an A-A cutaway view of the present utility model;

The utility model embodiment:

The utility model mainly by column 1, heighten column 2, bolt 3, nut 4, spring washer 5, crossbeam 6 and cushion block 7 and form.Wherein bolt, nut, spring washer, crossbeam are selection standard spare.Column 1 is got and is widely made for the channel-section steel of 100mm, and two holes of φ 21 are arranged in the bottom.Heighten column 2 and get and widely make, on the channel-section steel bottom surface, mill the rectangular slot of 22 * 275mm for the channel-section steel of 120mm.

Cushion block 7 is welded in the place, two holes of column 1 respectively, crossbeam 6 welding two columns 1 upper end becomes the H type, heighten the hole that column 2 and column 1 usefulness bolt 3 pass rectangular slot, cushion block 7 and the column 1 of heightening column 2, put spring washer 5, screw on nut 4 column 1 with heighten column 2 and be fixedly connected, form support between the adjustable senior middle school of travelling apron.
