Abstract

The utility model discloses a stretching and straightening device for a sucker rod, which comprises a machine frame. The front end and the rear end of the machine frame are respectively provided with clamping heads which are provided with mechanical grippers, the two mechanical grippers are respectively and symmetrically arranged on two sides of the center of the clamping heads in rotatable mode, the sucker rod to be straightened is arranged between the two clamping heads and clamped by the mechanical grippers, the two clamping heads are respectively connected with a stretching oil cylinder, and the stretching oil cylinders push the clamping heads to move lengthways on the machine frame. The clamping heads which are provided with the mechanical grippers are adopted by the stretching device for straightening the sucker rod to automatically clamp the sucker rod, the clamping heads are pushed by the stretching oil cylinder to move lengthways to straighten the sucker rod, and manual intervening operations are not needed during operation process, thereby reducing working strength of operators, improving straightening quality of the sucker rod, further enabling comprehensive mechanical property of the sucker rod to satisfy using requirements.

Description

Sucker rod alignment stretching device

Technical field

The utility model relates to a kind of sucker rod alignment stretching device.

Background technology

Sucker rod is as the critical piece of oil recovery machiner, its performance requirement: the one, and the mechanical property of sucker rod will be consistent vertically; The 2nd, sucker rod can not be out of shape, satisfy certain linearity requirement, therefore after sucker rod carries out the Technology for Heating Processing of Q-tempering, all need the sucker rod that the goes out tempering furnace alignment that stretches, but the common employing of existing sucker rod alignment mode clamps clamp plate type and carries out, in alignment process, tend to occur the nose phenomenon, need to have improved operating personnel's working strength unintentionally by the manual intervention operation.

The utility model content

The technical problems to be solved in the utility model is: overcomes the deficiency in the prior art, a kind of sucker rod alignment stretching device is provided,

The technical scheme that its technical problem that solves the utility model adopts is: a kind of sucker rod alignment stretching device, comprise frame, described frame front and back ends is respectively equipped with the clamping head with mechanical handgrip, described mechanical handgrip quantity is two, two rotatable respectively both sides, clamping head center that are symmetricly set on of mechanical handgrip, the sucker rod for the treatment of alignment clamps between two clamping heads and by mechanical handgrip, two clamping heads are connected with the stretching oil cylinder respectively, and the stretching oil cylinder promotes the clamping head and vertically moves on frame.

Specifically, described clamping head comprises pedestal, be provided with cylinder in the pedestal, be connected with pushing block on the piston rod of cylinder, pushing block and two mechanical gripping palmistrys connect, be fixed with the mechanical finger that clamps sucker rod on the relative clamping area of two mechanical handgrips respectively, cylinder promotes two mechanical handgrips by pushing block and does open and close movement and clamp or unclamp sucker rod.

For improving the clamping force of mechanical handgrip, also be provided with on the described pedestal and be used to depress two mechanical handgrips to clamp the stage clip of sucker rod.

The beneficial effects of the utility model are: the utility model adopts the clamping head that has mechanical handgrip to clamp sucker rod automatically, promoting the clamping head by the stretching oil cylinder vertically moves sucker rod is carried out alignment, need not the manual intervention operation in the operating process, alleviated operating personnel's working strength, improved the alignment quality of sucker rod, thereby made the comprehensive mechanical property of sucker rod satisfy instructions for use.

The specific embodiment

In conjunction with the accompanying drawings the utility model is further described now.The schematic diagram that these accompanying drawings are simplification only illustrates basic structure of the present utility model in a schematic way, so it only shows the formation relevant with the utility model.

A kind of sucker rod alignment stretching device as shown in Figure 1, comprise frame 1, described frame 1 front and back ends is respectively equipped with the clamping head 3 with mechanical handgrip 2, described mechanical handgrip 2 quantity are two, two rotatable respectively both sides, clamping head 3 center that are symmetricly set on of mechanical handgrip 2, the sucker rod 4 for the treatment of alignment clamps between two clamping heads 3 and by mechanical handgrip 2, two clamping heads 3 are connected with stretching oil cylinder 5 respectively, frame 1 two ends are fixed with slide rail 12 respectively, and stretching oil cylinder 5 promotes clamping head 3 and vertically moves on slide rail 12.

Specifically, as shown in Figure 2, described clamping head 3 comprises pedestal 6, be provided with cylinder 7 in the pedestal 6, be connected with pushing block 9 on the piston rod 8 of cylinder 7, pushing block 9 links to each other with two mechanical handgrips 2, be fixed with the mechanical finger 10 that clamps sucker rod 4 on the relative clamping area of two mechanical handgrips 2 respectively, cylinder 7 promotes two mechanical handgrips 2 by pushing block 9 and does open and close movement and clamp or unclamp sucker rod 4, on pedestal 6, also be provided with simultaneously two stage clips 11, two stage clip 11 respectively corresponding two mechanical handgrips 2, it is closed and when clamping sucker rod 4 to retreat the mechanical handgrip of pulling 2 at cylinder 7, two stage clips 11 are depressed each self-corresponding mechanical handgrip 2 respectively with clamping sucker rod 4, thereby improve the clamping force of mechanical handgrip 2.After machinery handgrip 2 clamped sucker rod 4, stretching oil cylinder 5 started, and promoted clamping head 3 and moved and stretching alignment sucker rod 4 on slide rail 12.

The utility model adopts the clamping head 3 that has mechanical handgrip 2 to clamp sucker rod 4 automatically, promoting clamping heads 3 by stretching oil cylinder 5 vertically moves sucker rod 4 is carried out alignment, during stretching, the operating pressure of stretching oil cylinder 5 is 25Mpa, pulling force is not less than 630KN, after sucker rod 4 puts in place, automatically clamp the sucker rod 4 and the alignment that stretches by computer control system control clamping head, need not the manual intervention operation in the operating process, thereby alleviated operating personnel's working strength, improve the alignment quality of sucker rod 4, made the comprehensive mechanical property of sucker rod 4 satisfy instructions for use.

Above-mentioned embodiment only is explanation technical conceive of the present utility model and characteristics; its purpose is to allow the personage that is familiar with this technology can understand content of the present utility model and is implemented; can not limit protection domain of the present utility model with this; all equivalences of doing according to the utility model spirit essence change or modify, and all should be encompassed in the protection domain of the present utility model.
