Abstract
The utility model provides a narrow space bolt-on device to overcome in the narrow space through the difficult problem that the staff can't fasten the bolt, promote the compactness that the pipeline is connected, and be applicable to the bolt of different models and the narrow space of different length uses. The transmission mechanism comprises an upper strip-shaped plate and a lower strip-shaped plate which are arranged in parallel and are connected into a whole through a connecting bolt, wherein a row of transmission gears are arranged between the upper strip-shaped plate and the lower strip-shaped plate, and two adjacent transmission gears are meshed; the transmission gear close to the end part of one side of the upper strip-shaped plate and the lower strip-shaped plate is a driving gear, and a driving shaft of the transmission gear extends downwards to form a lower strip-shaped plate surface. Through holes are arranged on the upper strip plate at equal intervals from the driving gear to one side end part of the upper strip plate and the lower strip plate, and a connecting structure matched with the toothed sleeve is arranged on the end surface of the transmission gear below each through hole.
Description
Technical Field
The utility model relates to a subway installation engineering construction tool, in particular to narrow space bolt-up device.
Background
In subway installation projects, the air pipes are often installed against a top structural plate under the limitation of structure and decoration elevation. Because tuber pipe width overlength and the space between tuber pipe and the structural slab is narrow, lead to the constructor can't fasten the bolt of the continuous flange in tuber pipe middle part.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that a narrow space bolt-up device is provided to can't carry out the difficult problem that fastens through the staff in overcoming narrow space, promote the compactness that the pipeline is connected, and be applicable to the bolt of different models and the narrow space of different length uses.
The utility model provides a technical scheme that its technical problem adopted as follows:
the utility model discloses a narrow space bolt-up device, characterized by: the transmission mechanism comprises an upper strip-shaped plate and a lower strip-shaped plate which are arranged in parallel and connected into a whole through a connecting bolt, wherein a row of transmission gears are arranged between the upper strip-shaped plate and the lower strip-shaped plate, and two adjacent transmission gears are meshed; the transmission gear close to one side end of the upper strip-shaped plate and one side end of the lower strip-shaped plate is a driving gear, and a driving shaft of the transmission gear extends downwards to form a lower strip-shaped plate surface; through holes are arranged on the upper strip plate at equal intervals from the driving gear to one side end part of the upper strip plate and the lower strip plate, and a connecting structure matched with the toothed sleeve is arranged on the end surface of the transmission gear below each through hole.
The utility model has the advantages that the upper strip-shaped plate, the lower strip-shaped plate and the row of transmission gears between the upper strip-shaped plate and the lower strip-shaped plate form a strip-shaped assembly which can conveniently extend into a narrow space, the tooth-shaped sleeve is arranged on the transmission gear at a proper position, and the driving shaft at one side end part of the strip-shaped assembly is twisted, so that the bolt in the narrow space can be conveniently fastened, and the tightness of pipeline connection is improved; the tooth-shaped sleeves with different specifications can be suitable for bolts with different models and narrow spaces with different lengths.
Drawings
The specification includes the following three figures:
fig. 1 is a front view of a bolt fastening device for a narrow space according to the present invention;
fig. 2 is a plan view of a bolt fastening device for a narrow space according to the present invention;
fig. 3 is a right side view of a bolt fastening device for a narrow space according to the present invention;
the figures show the components and corresponding references: an upper strip-shaped plate 11, a lower strip-shaped plate 12, a connecting bolt 13, a transmission gear 20, a toothed sleeve 21 and a driving shaft 22.
Detailed Description
The present invention will be further described with reference to the accompanying drawings and examples.
Referring to fig. 1 to 3, the utility model discloses a narrow space bolt-on device includes parallel arrangement and connects last strip shaped plate 11, lower strip shaped plate 12 as an organic whole through connecting bolt 13, sets up one row of drive gear 20 at last strip shaped plate 11, the installation between lower strip shaped plate 12, and two adjacent drive gear 20 form the meshing. The transmission gear 20 close to the end part of one side of the upper strip-shaped plate 11 and the lower strip-shaped plate 12 is a driving gear, a driving shaft 22 of the transmission gear is extended downwards to form the surface of the lower strip-shaped plate 12, and the driving shaft 22 can be rotated by a wrench to drive each transmission gear 20 to rotate. The driving gear is arranged on one side end part of the upper strip-shaped plate 11 and one side end part of the lower strip-shaped plate 12, through holes are arranged on the upper strip-shaped plate 11 at equal intervals, a connecting structure matched with the toothed sleeve 21 is arranged on the end surface of the transmission gear 20 below each through hole, and the toothed sleeves 21 with different specifications are configured, so that the driving gear can be suitable for bolts with different models and narrow spaces with different lengths.
The above is only used for illustration of some principles of the bolt fastening device in narrow space, but not to limit the utility model to the specific structure and application range, so all corresponding modifications and equivalents that may be utilized all belong to the patent scope of the utility model.
