Abstract
The utility model discloses a hinge top beam lifter, which comprises a 'U'-shaped lifting hook and a straight lifting rod. The lifting rod is made of a steel pipe with a 1.5-meter length and a 6-decimeter diameter, the lifting hook can be made of 24-centemeter 16# threaded steel, and the lifting hook is welded at the top end of the lifting rod. The hinged top beam lifter is simple and practical in structure and safe and labor-saving in utilization, a screw nut is rotated by rotating a rotary handle to expand or retract the lifting rod for adjustment until reaching a proper height according the construction site condition and the height of a hinged top beam, a groove of the lifting hook at the upper end of the lifting rod is led to fasten a pin of the hinged top beam, consequentially the hinged top beam is extremely easy to be lifted, and then the process is completed by impacting an individual prop. The hinged top beam lifter omits aerial operation of workers, reduces labor intensity of the workers, improves labor efficiency, and is convenient and flexible in use. Additionally, the lifting rod of the hinged top beam lifter can be detached together along with the lifting hook from the screw nut for individual use of the lifting rod in a handholding manner.
Description
Technical field:
The utility model relates to a kind of machine tool, relates in particular to a kind of in the leading section in coal-face tunnel or generally adopt or when blast mining face uses individual prop and articulated roof beam supporting roof, be used to hold up the articulated roof beam outrigger device of articulated roof beam.
Background technology:
The colliery underworkings is crisscross, the leading section in coal-face tunnel or general adopting or blast mining face when using individual prop to add the articulated roof beam supporting roof, after articulated roof beam is hinged, new hinged articulated roof beam is that nature is sagging, in order to make articulated roof beam play the effect of supporting roof, at present, the operating personnel stands in hold in the palm articulated roof beam or use instruments such as spade with articulated roof beam jack-up of eminence generally speaking, and this method is heaviness but also dangerous not only.
The utility model content:
For the construction operation that solves the leading section in coal-face tunnel exists not science, unsafe problem, the purpose of this utility model provide a kind of safe in utilization, laborsaving, be exclusively used in and hold up or the articulated roof beam outrigger device of jack-up articulated roof beam.
The technical solution of the utility model realizes in the following manner:
A kind of articulated roof beam outrigger device, it is by choosing hook and rod is formed, and choosing hook is that one " U " shape is chosen hook, and rod is a straight-bar; Rod is that 6 decimeters steel pipe manufacturing forms by long 1.5 meters, diameter, chooses the top that hook is welded on rod.
Described rod lower end connects a screw by screw, and screw is connected with screw mandrel on the base, and the screw outside connects a handler.
Choosing hook can use the 16# screw-thread steel of 25cm to make.
Good effect of the present utility model is:
1, simple in structure, practical.
2, safe in utilization, laborsaving, according to job site situation and hinged roof depth of beam, the rotation handler makes the screw rotation, make the flexible adjustment of rod, until proper height, the groove that makes its upper end choose hook blocks the pin of articulated roof beam, so just can be easy to provoke articulated roof beam, beating individual prop then gets final product, avoid workman's ascend operation, alleviated working strength of workers, improved efficiency.
3, easy to use, flexible, the rod of this articulated roof beam outrigger device can be laid down from screw together with choosing hook, hand-held rod uses separately.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the structural representation of the another kind of form of the utility model.
The specific embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing:
As seen from Figure 1: the utility model is by choosing hook 1 and rod 2 is formed, and choosing hook 1 is that one " U " shape is chosen hook, and rod is a straight-bar.
As seen from Figure 2: rod 2 lower ends connect a screw 4 by screw, and screw is connected with screw mandrel on the base 5, and the screw outside connects a handler 3 so that the rotation screw is regulated rod length.
