Description
Technical field
The utility model relates to the setting tool of underground coal mine laser spots, is specially a kind of new pattern laser frame.
Background technique
Colliery well lane engineering in tunneling process due to by Geological Structure Effect, often occur that roof and floor is gone up a hill and phenomenon of going down the hill, so just must carry out adjustment construction laser spots when constructing by geological survey portion, laser adjusts the tunneling direction affecting tunnel that not in time will be serious, especially when constructing belt tunnel, so the life cycle of laser spots is just shortened, bring very large trouble to construction team's group and ground survey group, be therefore starved of a kind of can the support of convenient, flexible adjustment laser positions.
Summary of the invention
The utility model be solve current underground coal mine laser spots lead time up and down position be difficult to the technical problem of convenient, flexible adjustment, a kind of new pattern laser frame is provided.
The utility model adopts following technological scheme to realize: a kind of new pattern laser frame, and comprise the first sleeve vertically arranged, the top of the first sleeve is fixed with first lockset, and in the first sleeve, movable sheath is provided with second sleeve; First sleeve is provided with first fixing bolt of locating the second sleeve near the sidewall of bottom port; In second sleeve, movable sheath is provided with the body of rod that a length is greater than the second sleeve, and the second sleeve is provided with second fixing bolt of locating the body of rod near the sidewall of bottom port; The body of rod lower end part be positioned at outside the second sleeve is horizontally rotated by the second lockset and is connected with one for installing the cross bar of laser.
By the feedback at scene and the design of theoretical property, utilize the principle of handle of umbrella, change the laser frame of traditional fixed into adjustable type, namely there is the telescopic adjustment up and down of the body of rod and the rotation regulatory function of cross bar, so just can meet the geological condition of work on the spot face complexity to greatest extent, substantially prolongs the life cycle of laser spots.
Technical characterstic of the present utility model: 1. stretchability: the body of rod can be gone up a hill according to tunnel and change of going down the hill is carried out extending or shrinking, and changes the drawback that conventional laser frame is non-telescoping.
2. revolving ability: traditional laser frame is fixed on cross bar by the lockset of fixed transverse rod, rotation before and after cross bar can only do, and the rotation of front and back adjusts without any effect the laser of working surface, and lockset is adjusted on the body of rod by this laser frame, can meet the rotation up and down of laser like this.
3. change the pattern that the monomer bar of original laser frame is fixing, and replace rotary laser equipment by rotary bar, enhance the stability of whole laser frame.
The investigation of the utility model according to job site and the research of some theoretical properties, machined a set of transformable laser frame, the solution geological structure of maximum possible can change the technical barrier that the laser caused cannot reach facies palmaris.

Embodiment
A kind of new pattern laser frame, the top comprising the first sleeve 1, first sleeve 1 vertically arranged is fixed with movable sheath in first lockset 2, first sleeve 1 and is provided with second sleeve 3; First sleeve 1 is provided with first fixing bolt 4 of locating the second sleeve 3 near the sidewall of bottom port; In second sleeve 3, movable sheath is provided with the body of rod 5, second sleeve 3 that a length is greater than the second sleeve 3 and is provided with second fixing bolt 6 of locating the body of rod 5 near the sidewall of bottom port; The body of rod 5 lower end part be positioned at outside the second sleeve 3 is horizontally rotated by the second lockset 7 and is connected with one for installing the cross bar 8 of laser.
The geological structure of more complicated is met in tunnel in work progress, can maintain by regulating laser frame and extend the life cycle of laser spots, when tunnel meet go up a hill time, the uphill slope in tunnel is met by extending the sleeve of laser frame, the body of rod and adjustment laser frame cross bar, when tunnel meet go down the hill time, meet the downhill slope in tunnel by shrinking the second sleeve of laser frame, the body of rod and adjustment laser frame cross bar.
Accompanying drawing is novel and part structures that is conventional laser frame.
1. traditional laser frame is made up of two bodies of rod, each body of rod is fixed a lockset, and one (the first lockset) is fixed on top board, and another (second lockset) is used for connection two bodies of rod.
2. Telescopic rotating laser frame is made up of three parts substantially, and wherein a lockset is welded in first sleeve one end of largest diameter, the other end sidewall is welded with two the first set screw nuts; The second sleeve that diameter is slightly little is free type, can slide in one end in large sleeve, and the other end is welded with two the second set screw nuts; A body of rod, the length of the body of rod is slightly larger than the length of the second sleeve, and wherein one end is welded with second lockset and fixes cross bar, and cross bar can rotate in the second lockset.
3. first, second length sleeve of stretchability laser frame is generally (in Fig. 1 L1, L2) 60cm, in conjunction with the body of rod, can be controlled in 60-180cm and regulates, and also can process according to concrete tunnel situation.
