Description
Technical field
A kind of development machine Bracket for supporting roof beam of the utility model belongs to coal mining driving technical field of auxiliary equipment.
Background technique
Bracket for supporting roof beam is a kind of tool used in coal production as tunnel girder steel supporting, it is mounted on tunneling machine cutting
The top of head can be by plate-girder or I-steel support in the position for needing gib.Unavoidable turn opening when digging laneway,
Machine driven headings when turning round opening, the erection of gib is always a difficult point, cooperates i-beam frame with unit Bracket for supporting roof beam
If gib, if as shown in Figure 1 and Figure 2, joist slot 1 and joist arm 2 on Bracket for supporting roof beam are vertical using original Bracket for supporting roof beam
It is directly welded and fixed, plate-girder 3 can not be parallel with turning roadway after being placed in joist slot 1, does not have the effect of gib；With
Monomer column and the progress gib of π type beam, complex procedures, troublesome and safety coefficient are low.
Utility model content
A kind of development machine Bracket for supporting roof beam of the utility model, overcomes the shortcomings of the prior art, provides joist slot and joist
Arm angle is adjustable, can be applied to construct horizontal river or chamber turns round the development machine Bracket for supporting roof beam of opening.
In order to solve the above-mentioned technical problem, the technical solution adopted in the utility model are as follows: a kind of development machine Bracket for supporting roof beam, including
Joist arm and joist slot, joist slot are rotatably installed on joist arm, and being provided on joist arm and joist slot can be to joist slot
The positioning mechanism positioned.
Further, the positioning mechanism includes several apertures being arranged on joist arm and joist slot, joist arm and joist
Slot is adjusted to after proper angle, is fixed joist arm and joist slot by bolt.
Further, the quantity of the aperture is 5, and the position of the aperture is located at joist arm and joist slot overlapping portion
Divide rectangular four angles formed and rectangular diagonal line intersection point.
Further, the positioning mechanism includes several apertures in the curved opening being arranged on joist slot and joist arm, support
Beam arm and joist slot are adjusted to after proper angle, are fixed joist arm and joist slot by bolt.
Compared with prior art, the utility model has the beneficial effect that the utility model structure is simple, applies in coal mine
The horizontal river of work or chamber turn round opening when, by adjusting the joist angle of the v-groove, ensure that the normal of during turn plate-girder or I-steel
It uses, it is ensured that the coverage area of gib, it is ensured that effective, the safety of gib during turn.

Specific embodiment
The utility model is described further with reference to the accompanying drawing.
Embodiment one
As shown in figure 3, a kind of development machine Bracket for supporting roof beam of the utility model, including joist arm 1 and joist slot 2, joist slot 2 can revolve
It is mounted on joist arm 1 with turning, the positioning mechanism that can be positioned to joist slot 2 is provided on joist arm 1 and joist slot 2.
Positioning mechanism includes 5 apertures 7 being arranged on joist arm 1 and joist slot 2, and joist arm 1 is arrived with the adjusting of joist slot 2
It is by bolt that joist arm 1 and joist slot 2 is fixed after proper angle.The position of aperture 7 is located at joist arm 1 and joist slot 2
Rectangular four angles and rectangular diagonal line intersection point that lap is formed.As shown in figure 5, passing through joist arm 1 and joist
The positioning in five holes between slot 2, allows the right rotation to the left of joist slot, and the joist angle of the v-groove is adjustable.
Embodiment two
For simplicity narration, the distinctive points of embodiment two Yu embodiment one are only described.
As shown in figure 4, positioning mechanism includes several apertures 7 in the curved opening 8 and joist arm 1 being arranged on joist slot 2,
Joist arm 1 and joist slot 2 are adjusted to after proper angle, by bolt that joist arm 1 and joist slot 2 is fixed.Under such mode, support
Beam arm 1 can be adjusted at any angle with joist slot 2 in the range of curved opening 8, be applicable in a variety of construction operating conditions.
Joist arm 1 and joist slot 2 form trailing arm device, and trailing arm device is mounted on the cutting arm 5 of development machine, 2 restocking of joist slot
If plate-girder 3, gib is formed in the top being located at cutterhead 4, it is ensured that the peace of gib when turn excavation operation
Entirely.
The embodiments of the utility model have been described in detail above with reference to the accompanying drawings, but the utility model is not limited to
Embodiment is stated, within the knowledge of a person skilled in the art, the utility model aims can also not departed from
Under the premise of various changes can be made.
