Abstract
The present invention discloses a locking protection mechanism for an automatic pipeline joint coating sealing deruster, wherein the locking protection mechanism is specially designed for transverse walking device protection. According to the present invention, an operation pressing handle is adopted to drive an eccentric pressing block to rotate, an eccentric amount change of the eccentric pressing block is adopted to drive a pressing shaft to overcome spring resistance so as to move up and down, and connection rod swing is pulled so as to push a clamping block to move left and right, such that an arc surface on the head part and a guide light rod are attached and separated so as to achieve locking and releasing of the transverse walking device; and the locking protection mechanism has characteristics of simple structure and convenient operation, wherein the transverse walking device can be protected during a transportation process with the locking protection mechanism, such that a worm wheel worm and a constant speed gear set can be protected from damage caused by external force.
Description
Technical field
The present invention relates to the automatic closed derusting machine of pipeline repaired mouth locking protection mechanism, belong to oil and gas pipeline construction technique field.
Background technology
Long distance pipeline is formed by the many single pipe docking that are about 11 meters.In the construction, the welding region of pipeline joint need be done preventing corrosion of repaired mouth and process, and the antiseptic first step is that welding region is carried out surface treatment.At present, open artificial derusting by sandblasting is still adopted in the surface treatment during the pipeline girth weld repaired mouth.Operating personnel's level difference and randomness cause the steel tube surface cleannes after the blasting treatment inconsistent, and open sandblast meeting causes the serious waste of abrasive material and the pollution of environment, so that workman's health status and joint coating on pipeline quality all can not well be guaranteed.Therefore, the joint coating on pipeline rust remover with automation, airtight environment protection-type arises at the historic moment, and will replace gradually coarse and crude artificial open rust cleaning and becomes leading in the pipeline construction.
Summary of the invention
The object of the present invention is to provide a kind of automatic closed derusting machine of pipeline repaired mouth locking protection mechanism, it can play a protective role by the horizontal walking device to rust remover in transportation.
Technology contents of the present invention is as follows:
Be provided with row's installing hole at the horizontal mobile device base plate, the interstitial hole top is provided with the concentric supporting base of centre bore, also is provided with the both sides pin rod that band connects pin-and-hole on the supporting base.Last item pass the supporting base centre bore and by spring supporting between the pin rod of both sides.Above last item, connect pressure handle, with the eccentric briquetting of eccentric pin hole by straight pin with connect pin-and-hole and be connected between the pin rod of both sides.Holding pin is located in the both sides installing hole symmetrical on the base plate, clamp is located in the circular hole of holding pin end, the head of clamp is the cambered surface identical with the guiding polished rod, and its afterbody is provided with slot and the pin-and-hole that connects connecting rod, and the other end of connecting rod connects last item by fixed block.
The present invention drives eccentric briquetting by the operation pressure handle and rotates, change the upper and lower motion of band dynamic pressure shaft against the force of the spring by its offset, and affect connecting rod swing, and then the left and right movement of promotion clamp, make its head cambered surface and guiding polished rod fit and separate, thereby realization is to locking and the relieving of horizontal walking device.This locking protection mechanism is simple in structure, easy to operate, can protect horizontal walking device in transportation, makes its worm and gear and constant speed gear train avoid damage.

The specific embodiment
Referring to figs. 1 through Fig. 7 embodiments of the invention are described.
Embodiment:
Skeleton 1 at automatic closed derusting machine of pipeline repaired mouth is provided with steering mechanism 2, horizontal mobile device 3, quick clamping mechanism 4 and walking driving mechanism 5, and locking protection mechanism of the present invention is located on the horizontal mobile device 3.
At horizontal mobile device base plate 63 installing holes are set, installing centre bore concentric supporting base 15 in interstitial hole top also is provided with the both sides pin rod that band connects pin-and-hole on the supporting base 15, uses bullet pad 13 and screw 14 with supporting base 15 lockings.Last item 16 is passed supporting base 15 centre bores and be supported between the pin rod of both sides by spring 17.Above last item 16, the connection pin-and-hole that utilizes straight pin 18 to be connected with the both sides pin rod is connected in eccentric briquetting 19 between the pin rod of both sides, with threaded engagement pressure handle 20 is connected with eccentric briquetting 19.With plain cushion 10, bullet pad 11 and nut 12 holding pin 9 is locked in the both sides installing hole symmetrical on the base plate 6, clamp 8 is through in the circular hole of holding pin 9 lower ends, make its head cambered surface applying guiding polished rod 7 surfaces, connecting rod 21 is connected in the slot of clamp 8 afterbodys with pin 22 again, then connecting rod 21 other ends is connected with last item 16 by fixed block 23.With plain cushion 24, spring shim 25 and nut 26 last item 16 bottoms are locked.
