Abstract
The utility model discloses an improved pipe fitting clamping device. The improved pipe fitting clamping device comprises a fixing table and two pneumatic cylinders fixed on the fixing table, wherein two ends of the fixing table protrudes, the pneumatic cylinders are located on the same straight line and oppositely arranged and fixed on protrusions, clamping devices are fixed on piston rods of the pneumatic cylinders, guide rails are further arranged on the fixing table, and sliding devices are fixed at the bottom ends of the clamping device and are located on the guide rails. The improved pipe fitting clamping device has the advantages that the piston rods of the pneumatic cylinders does not easily break, the replacement frequency of the pneumatic cylinders is reduced, and the purpose of saving the cost is achieved.
Description
Technical field
The utility model relates to a kind of clamping device, relates to a kind of follow-on pipe fitting clamping device in particular.
Background technology
Drilling rod is the steel pipe that afterbody has a chain for binding criminals line, is used for connecting the rig landscape apparatus and is positioned at the drilling well bottom boring mill equipment or bottom outlet device.The purposes of drilling rod is that drilling mud is transported to drill bit, and improves, reduces or rotate the bottom outlet device with drill bit.When making oil drill rocker, need make the drilling rod lines at the raw material of making drilling rod, to meet the instructions for use of drilling rod.Existing pipe fitting clamps aid, is that piston rod directly is connected with clamping device, because clamping device and drilling rod all is metal material, quality is very heavy.In use, piston rod is easy to fracture owing to hold weight that can't stand clamping device and drilling rod.Not only influence use behind the rod fracture, and pneumatic cylinder can not re-use.The pneumatic cylinder that more renews is waste material not only, and increases personnel's labour intensity.
The utility model content
The utility model has overcome the deficiencies in the prior art, and a kind of follow-on pipe fitting clamping device is provided, and the piston rod of the pneumatic cylinder of this device is easy fracture not, reduces the frequency that pneumatic cylinder is changed, to reach the purpose of saving cost.
For solving above-mentioned technical problem, the utility model by the following technical solutions:
Modified pipe fitting clamping device, it comprises fixed station and two pneumatic cylinders that are fixed on the fixed station, the two ends projection of described fixed station, described pneumatic cylinder is located along the same line and puts relatively and pneumatic cylinder is fixed on the projection, clamping device is fixedly arranged on the piston rod of described pneumatic cylinder, also be provided with guide rail on the described fixed station, fixedly there is carriage the bottom of described clamping device, and this carriage is positioned on the guide rail.
Clamping device of the present utility model links to each other with guide rail by the carriage of its bottom, draws close mutually when compressing drilling rod when pneumatic cylinder promotion clamping device, and clamping device equally also slides at guide rail.Guide rail bears the weight of clamping device and drilling rod, makes piston rod not be subjected to pullling of downward force, and its piston rod can not ruptured, and strengthens its service life, economical with materials.
Further technical scheme is:
Described clamping device comprises shell and two fixing cylinders in the enclosure, and described cylindrical two ends are fixed on the shell and a cylindrical part is positioned at enclosure.
Four cylinders in two clamping devices of the present utility model cooperatively interact and drilling rod can be clamped, and a cylindrical part is positioned at outside the shell, could satisfy the requirement that clamps drilling rod.
Described guide rail horizontal positioned and be positioned on the same vertical line with pneumatic cylinder.
Guide rail horizontal positioned of the present utility model, and be positioned on the same vertical line with pneumatic cylinder when pneumatic cylinder promotes clamping device and moves, could guarantee that clamping device all the time in the guide rail movement, is difficult for departing from guide rail.
On the described pneumatic cylinder air inlet is arranged, the air inlet of two pneumatic cylinders is connected in same admission line.
Two air inlets of the present utility model are connected on the same admission line, open the valve of admission line, and the air-flow of two air inlets just can be even, and two clamping devices just can move to the direction that is close to drilling rod with identical progress.
On the described pneumatic cylinder exhaust outlet is arranged, the exhaust outlet of two pneumatic cylinders is connected in same discharge duct.
Two exhaust outlets of the present utility model are connected on the same discharge duct, open the valve of discharge duct, and the air-flow of two exhaust outlets just can be even, and two clamping devices just can move to the direction away from drilling rod with identical progress.
Compared with prior art, the beneficial effects of the utility model are:
1, clamping device of the present utility model links to each other with guide rail by the carriage of its bottom, when pneumatic cylinder moves at the promotion clamping device, guide rail bears the weight of clamping device and drilling rod, make piston rod not be subjected to pullling of downward force, its piston rod can not ruptured, strengthen its service life, economical with materials.
2, of the present utility model simple in structure, easy to operate.
