Detailed Description
In order to make the objects, technical solutions and technical effects of the present invention clearer, the present invention will be further described in detail with reference to the accompanying drawings and specific embodiments. It should be understood that the detailed description and specific examples, while indicating the present invention, are given by way of illustration and not limitation.
Referring to fig. 1, the utility model discloses a frock is installed and removed to bolt includes:
a sleeve 10, wherein the sleeve 10 is provided with a containing space 100;
a long rod screw 20 accommodated in the accommodating space 100 and capable of rotating and moving up and down in the accommodating space 100, wherein a handle 30 is provided at a top end of the long rod screw 20, and a butt joint portion (not labeled) for butt joint with a bolt to drive the bolt to be screwed or unscrewed is provided at a bottom end of the long rod screw 20; and
the sleeve head 40 is arranged at the bottom end of the sleeve 10, and the sleeve head 40 is provided with a cavity 400 matched with the bolt in shape.
According to the utility model discloses an embodiment of frock is installed and removed to the bolt, the top both sides of sleeve 10 are equipped with handle 50 to make things convenient for the bolt to install and remove the frock to screwing, the pine of unscrewing and carrying of bolt. The handle 50 has sufficient strength to withstand the bending moment of the bolt mounting and dismounting tool during the mounting and dismounting of the bolt, and for example, the handle 50 may be made of a steel pipe having sufficient strength. In the embodiment shown in fig. 1, the handle 50 is located below the handle 30, and the handle 50 is symmetrically welded to the outer sidewall of the sleeve 10. The sleeve 10 also needs to have a certain wall thickness to withstand the torque generated during the process of screwing or unscrewing the bolt during the bolt assembling and disassembling process, so as to ensure that the sleeve is not deformed.
The handle 30 is welded on the top end of the long rod screw 20 and can be set into a horizontally arranged steel pipe, the length of the handle 30 is larger than the inner diameter of the accommodating space 100, on one hand, the long rod screw 20 is driven through the handle 30 to realize the screwing or unscrewing of the bolt, on the other hand, the long rod screw 20 can be prevented from falling off from the accommodating space 100, and the normal use of the bolt assembling and disassembling tool is influenced.
The length of stock screw 20 slightly is greater than the length of sleeve 10 to guarantee that the external screw thread that sets up in stock screw 20 bottom can with set up the internal thread in the screw hole at bolt top can normal threaded connection. In the in-service use in-process, the deep hole degree of depth of as required work can be according to the length of in-service use requirement adjustment sleeve 10 and the stock screw 20 of installing in sleeve 10 to with the bolt and the interval adaptation between the accessible position of staff, and then realize the installation and the dismantlement of bolt.
The sleeve head 40 is welded at the bottom end of the sleeve 10, the sleeve head 40 is provided with a cavity 400, and the shape and the size of the cavity 400 are matched with those of the bolt, so that when the bolt is installed and disassembled, the cavity 400 can be tightly sleeved on the bolt, and accurate installation and disassembly of the bolt can be realized.
In the embodiment shown in fig. 1, a ring-shaped boss 402 is provided on the inner wall of the sleeve head 40, and the long rod screw 20 is correspondingly provided with a stopper 102 located below the boss 402, and the boss 402 can limit the stopper 102 from moving toward the handle 30. The arrangement of the handle 30 can limit the long rod screw 20 to move up and down along the sleeve 10 within a certain range.
It should be noted that, the arrangement of the abutting portion at the bottom end of the long rod screw 20 is not particularly limited as long as it can be firmly abutted with the bolt to drive the bolt to be screwed or unscrewed. For example, according to an embodiment of the present invention, the top of the bolt is provided with a threaded hole with an internal thread, and the butt portion of the long rod screw is provided with an external thread matching the internal thread.
The working principle of the bolt assembling and disassembling tool of the present invention is described in detail below with reference to fig. 1.
When fastening a bolt in a long-distance and narrow space, firstly, the handle 30 is pressed downwards to drive the long-rod screw 20 to move along the sleeve 10 until the external thread at the bottom end of the long-rod screw 20 is exposed out of the sleeve head 40; secondly, the bolt is screwed on the long-rod screw 20 through the thread fit between the internal thread in the threaded hole at the top of the bolt and the external thread on the long-rod screw 20, and then the handle 30 is pulled upwards to place the bolt into the sleeve head 40; and finally, putting the bolt assembling and disassembling tool into the corresponding bolt hole in the narrow space for bolt fastening, screwing out the long rod screw 20 after fastening is finished, and taking out the bolt assembling and disassembling tool.
When the bolt dismounting work in a long-distance and narrow space is carried out, firstly, the bolt dismounting tool is placed in the narrow space, and the bolt is sleeved in the sleeve head 40; secondly, screwing the long rod screw 20 into a threaded hole in the top of the bolt, and connecting the internal thread in the threaded hole in the top of the bolt with the external thread on the long rod screw 20 through threads; and finally, screwing off the bolt by using the bolt assembling and disassembling tool, and taking out the bolt and the bolt assembling and disassembling tool together.
It can be seen from combining the above detailed description to the embodiment of the utility model discloses the bolt is installed and is removed the frock and be equipped with long-pole screw 20 and be located the butt joint portion of long-pole screw 20 bottom, when sleeve 10 extends to the bolt that needs the installation and dismantle, cavity 400 cover on the pullover 40 is established on the bolt, the butt joint portion and the bolt butt joint of long-pole screw 20 bottom, can realize screwing or the unscrewing of bolt through handle 30 drive long-pole screw 20, be applicable to the unable remote that gets into of people and the staff can't touch, bolt installation and dismantlement operation in the narrow and small space, show improvement operating efficiency.
