Abstract
The utility model relates to an instrument, an instrument that is used for narrow space to become sharp fastening with rotatory fastening, include, sleeve, ratchet, rotatable round pin axle, take hydraulic drive's anchorage bar, hydraulic pressure hand pump, rotatable round pin axle one side is connected with the sleeve through the belt, and the meshing of sleeve one end has the ratchet, and rotatable round pin axle below is provided with takes hydraulic drive's anchorage bar, takes hydraulic drive's anchorage bar department external to have hydraulic pressure hand pump. After adopting above-mentioned structure, through changing the motion form, solve the bolt fastening and the dismantlement in narrow and small space.
Description
Technical Field
The utility model relates to an instrument realizes changing into linear motion at the bolt-up in narrow and small space and dismantlement by rotary motion.
Background
A lot of bolts are located in narrow space in an equipment installation site, especially bolts larger than 20mm are fastened and disassembled, and due to the fact that conventional wrenches are fastened in a rotating mode, the bolts cannot be used normally due to the fact that the conventional wrenches are limited in space. Because the space is narrow, spanner turning radius is big, can not use, and rag bolt is in motor casing below, and the bolt can not expose completely, causes also can't use straight-bar extension spanner direct fastening. The purpose of this device is to solve the bolt fastening and the dismantlement in narrow and small space.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a be used for narrow space to become the instrument that sharp fastening was fastened with rotatory fastening to the above-mentioned problem exactly.
The purpose of the utility model is realized like this: the utility model provides an instrument that is used for narrow space to become sharp fastening with rotatory fastening, includes, sleeve, ratchet, rotatable round pin axle, takes hydraulic drive's anchorage bar, hydraulic hand pump, and rotatable round pin axle one side is connected with the sleeve through the belt, and the meshing of sleeve one end has the ratchet, and rotatable round pin axle below is provided with takes hydraulic drive's anchorage bar, and it has hydraulic hand pump to take hydraulic drive's anchorage bar department to connect outward.
Further, the ratchet wheel is arranged in the belt between the sleeve and the rotatable pin shaft.
The utility model has the advantages that:
the utility model adopts the above structure, through changing the motion form, solve the bolt-up and the dismantlement in narrow and small space.
Drawings
The present invention will be further described with reference to the accompanying drawings.
Fig. 1 is a schematic structural diagram of the present invention.
Fig. 2 is a schematic structural diagram of the utility model after rotation.
Fig. 3 is a schematic structural diagram of the utility model after rotation.
Wherein: 1. sleeve, 2 ratchet, 3 rotatable pin, 4 fastening rod with hydraulic transmission, 5 hydraulic manual pump, 6 motion radius.
Detailed Description
The tool comprises the following structures:
1. the sleeve 1, the sleeve can be selected according to the bolt specification, firstly the sleeve with the ratchet 2 is placed on the bolt.
2. The ratchet 2 can be locked by the ratchet to bear fastening torque in the process of fastening the bolt, and can be released after being fastened. By draining oil through the manual hydraulic pump 5, the fastening rod 4 with hydraulic transmission is pulled back to be ready for next fastening.
3. A rotatable pin 3, through which pin 3 the ratchet 2 is connected to a fastening rod 4 with hydraulic drive.
4. The fastening rod 4 with hydraulic transmission extends out through the hydraulic manual pump 5 to transmit fastening torque.
This device is through shortening fastening bolt's radius of rotation, and the extension fastening rod makes the fastening change the rectilinear motion mode into by the rotation mode, comes the bolt-up and dismantles in the suitable narrow and small space. The movement process is as follows:
1. a state to be fastened:
the hydraulic manual pump 5 releases oil, the ratchet 2 is released, and the fastening rod 4 with hydraulic transmission is contracted to the bottom of the hydraulic cylinder through the rotatable pin shaft 3 to prepare fastening.
2. And (3) a fastening process:
the hydraulic manual pump 5 supplies oil, the hydraulic transmission fastening rod 4 extends out, the ratchet wheel 2 is locked, fastening torque is transmitted to the ratchet wheel through the rotatable pin shaft 3, the sleeve and the ratchet wheel rotate together, and the nut is fastened.
The device uses a fastening head which can replace a sleeve with a large and a small belt pin shaft and rotate forward and backward, and is matched with a hydraulic pump to realize reciprocating motion, so that a bolt is fastened and detached. The bolt fastening mode is changed from a rotating mode to a linear mode, so that the bolt fastening and dismounting in a narrow space are adapted, and the bolt fastening and dismounting in the narrow space are realized.
The above description is only for the specific embodiment of the present invention, but the structural features of the present invention are not limited thereto, and any person skilled in the art can make changes or modifications within the scope of the present invention.
Claims (2)
1. A tool for changing a rotational fastening into a linear fastening in a narrow space, characterized in that: the hydraulic manual pump comprises a sleeve, a ratchet wheel, a rotatable pin shaft, a fastening rod with hydraulic transmission and a hydraulic manual pump, wherein one side of the rotatable pin shaft is connected with the sleeve through a belt, the ratchet wheel is meshed with one end of the sleeve, the fastening rod with the hydraulic transmission is arranged below the rotatable pin shaft, and the hydraulic manual pump is externally connected to the fastening rod with the hydraulic transmission.
2. A tool for converting a rotary fastening into a linear fastening for a narrow space according to claim 1, wherein: the ratchet wheel is arranged in the belt between the sleeve and the rotatable pin shaft.
