Description
The technical field is as follows:
the invention relates to the field of drilling tools, in particular to an opening and closing tool special for a rotary table locking pin.
Background art:
the locking and unlocking of the rotary table is a link frequently involved in the drilling production activity. At present, most of the tightening devices of the turntables are designed into locking pin structures. Taking the most common ZP275 rotary table as an example, the structure of the locking pin of the rotary table is generally a cylindrical pin main body and a cylindrical head connected with the end of the main body, the two cylindrical parts are perpendicular to each other, and the locking pin can slide back and forth in the pin groove along the axial direction of the pin main body under the action of external force, thereby realizing the opening and locking of the rotary table.
If the rotary table is a new rotary table, the operation can be completed by bare hands, but in more cases, the rotary table on the drilling site is rusted and stuck because of being soaked in slurry and corroded for a long time, so that the operation by bare hands can be almost impossible to complete, and in this case, the operation can be completed only by means of a crowbar and a hammer. For bare-handed operation, if the misoperation turntable is in a running state, instantaneous bounce impact can be generated, the hands of a person are easily injured, two persons are needed to cooperate with tools such as a crowbar and a hammer, and the hands, feet, even eyes and other important parts of the operator are easily injured during knocking operation. In addition, the locking pin body can be deformed by prying and smashing. Therefore, there is a need to develop a tool for opening and locking the locking pin of the rotary table.
The invention content is as follows:
in order to solve the problems, the invention provides a special tool for manually opening and locking a turntable locking pin.
The technical scheme of the invention is as follows:
a tool for opening and closing a locking pin of a rotary table comprises: a clamping part and a handle; the clamping part is a rectangular structure with a certain thickness and a square front surface, one thickness surface of the clamping part is fixedly connected with the handle as the bottom end surface of the clamping part, the thickness surface opposite to the bottom end surface is used as the top end surface of the clamping part, an inwards concave groove is arranged on the top end surface, a U-shaped notch is formed in the front end of the clamping part in the groove, and a C-shaped flexible hook which extends out along the thickness direction of the clamping part and is downward in a hook opening is symmetrically and fixedly connected to the two sides of the lower portion of the U-shaped notch.
Furthermore, the C-shaped flexible hook is of a sheet structure with the side width obviously larger than the thickness of the inner arc surface and the outer arc surface, and the inner arc profile of the C-shaped flexible hook is a semicircle or a major arc slightly larger than the semicircle.
Furthermore, a reinforcing rib plate is arranged at the joint of the C-shaped flexible hook and the clamping part, and is positioned below one side of a hook opening of the C-shaped flexible hook.
Further, the handle is in a rod shape, and the axial center line of the handle and the center line of the groove are on the same straight line.

The opening and closing tool for the turntable locking pin provided by the invention is simple in structure and convenient to use. The opening and closing tool can be used for easily realizing the opening and the locking of the turntable locking pin. The locking pin that leads to because of soaking for a long time, corrodes rusts the jamming, also can light, accomplish easily fast and open, the locking operation, effectively avoided bare-handed or with the help of tools such as crow bar, hammer operation cause waste time and energy and the poor problem of security.
Description of the drawings:
fig. 1 is a schematic structural view of the opening and closing tool for the locking pin of the turntable according to the present invention.
Fig. 2 is a side view of fig. 1.
Fig. 3 is a view from direction a of fig. 2.
Fig. 4 is a schematic structural view of the locking pin of the turntable locking pin of the present invention engaged with the opening and closing tool.
The specific implementation mode is as follows:
the technical solution of the present invention is described in detail below with reference to the accompanying drawings.
As shown in fig. 1, 2 and 3, the tool for opening and closing the locking pin of the turntable includes: an engaging part 1 and a handle 2; the clamping part 1 is a rectangular structure with a certain thickness and a square front surface, one thickness surface of the clamping part 1 is fixedly connected with the handle 2 as the bottom end surface of the clamping part 1, the thickness surface opposite to the bottom end surface is used as the top end surface of the clamping part 1, an inwards concave groove 11 is arranged on the top end surface, the groove 11 forms a U-shaped notch at the front end of the front surface of the clamping part 1, and a C-shaped flexible hook 3 which extends along the thickness direction of the clamping part 1 (namely, is vertical to the front surface of the clamping part) and has a downward hook opening is symmetrically and fixedly connected to the two sides of the lower part of the U-shaped.
Further, the C-shaped flexible hook 3 is a sheet structure with a side width significantly larger than the thickness of the inner and outer arc surfaces, and the inner arc profile is a semicircle or a major arc slightly larger than the semicircle. The sheet-shaped structure design of the C-shaped flexible hook 3 can effectively increase the firmness on the basis of saving raw materials; the design of the major arc structure with the inner arc profile of the hook opening being semicircular or slightly larger than the semicircle can further ensure the full occlusion of the flexible hook to the columnar head of the locking pin in the use state.
Furthermore, a reinforcing rib plate 4 is arranged at the joint of the C-shaped flexible hook 3 and the clamping part 1, and the reinforcing rib plate 4 is positioned below one side of the hook opening of the C-shaped flexible hook 3. The added reinforcing rib plate 4 and the position thereof can further increase the connection firmness and the stress strength of the C-shaped flexible hook 3 and the clamping part 1, and the problem that the connection part of the C-shaped flexible hook 3 and the clamping part 1 is deformed and even broken due to long-term use is avoided to the greatest extent.
Further, the handle 2 has a rod shape, and an axial center line thereof is aligned with a center line of the groove 11. This design enables the operator to more effectively transmit the force applied to the handle 2 to the engagement portion at the tip.
Furthermore, the engaging portion 1 and the handle 2, the engaging portion 1 and the C-shaped flexible hook 3, the engaging portion 1 and the reinforcing rib plate 4, and the C-shaped flexible hook 3 and the reinforcing rib plate 4 are integrally connected, and an integral welding method is adopted in the present embodiment, so that the firmness of the tool is improved as a whole.
When the tool is used on site, an operator holds the handle 2 of the turntable locking pin opening and closing tool, so that the groove 11 at the top of the clamping part 1 is pressed on the arc surface of the pin shaft main body 51 of the turntable locking pin 5, and the clamping of the clamping part 1 on the pin shaft main body 51 is formed; then, the engaging portion 1 is moved toward the columnar head portion 52 of the locking pin (with the engagement with the pin shaft body 51 being maintained) until the C-shaped flexible hook 3 hooks the columnar head portion 52 (i.e., the inner arc surface of the C-shaped flexible hook sufficiently contacts the outer peripheral surface of the columnar head portion 52), thereby completing the complete fixed engagement of the locking pin 5 by the turnplate locking pin opening and closing tool (shown in fig. 4). In the completely fixed engagement state, an operator applies a pushing force or a pulling force to the handle 2 substantially along the axial direction of the pin shaft main body 51 to the columnar head 52 through the C-shaped flexible hook 3 (inner arc surface), so that the pin shaft main body 51 moves, and the opening and locking of the turntable are completed. When the pin shaft main body 51 is difficult to move due to rusting and clamping stagnation, the pushing force or the pulling force applied to the handle 2 by an operator can also form lever force by taking the top of the clamping part 1 (two sides of the groove 11) as a fulcrum, and forms instant strong force application to the columnar head 52 through the C-shaped flexible hook 3, so that the original pushing force or the pulling force basically along the axial direction of the pin shaft main body 51 is changed into instant strong slightly-lifted pushing force or instant strong slightly-downward pulling force (the axial direction of the pin shaft main body 51 is taken as the horizontal direction), and the movement of the pin shaft main body 51 is realized.
The above embodiments are only for illustrating the present invention, and all equivalent changes and modifications made on the basis of the technical solutions of the present invention should not be excluded from the scope of the present invention.
