Detailed Description

The following detailed description of the embodiments of the present invention will be made with reference to the accompanying drawings. It is to be understood that the specific embodiments described herein are for purposes of illustration and explanation only and are not intended to limit the present invention.

The skid deformation correcting device according to the present invention is described below with reference to the accompanying drawings.

For the effectual special correction of realization to skid deformation, the utility model provides a skid deformation correcting unit. As shown in fig. 6-9, in one embodiment, a skid deformity correction device includes:

a straightening platform comprising a left stringer support platform 1 for supporting a left stringer 101 of skid 100 and a right stringer support platform 2 for supporting a right stringer 102 of skid 100;

the transverse correcting supports comprise a left transverse correcting support 5 fixedly arranged on the left longitudinal beam supporting platform 1 and a right transverse correcting support 6 fixedly arranged on the right longitudinal beam supporting platform 2, and the left transverse correcting support 5 and the right transverse correcting support 6 extend longitudinally and are transversely arranged in an opposite mode at intervals;

the vertical correcting support 7 is vertically arranged with the correcting platform at intervals, and the vertical correcting support 7 is arranged above the correcting platform and can move longitudinally;

and one end of the correcting mechanism is used for being connected with the transverse correcting support or the vertical correcting support 7, and the other end of the correcting mechanism is used for pressing and correcting the longitudinal beam of the skid.

As shown in fig. 1-5, skid 100 is generally a truss structure, with deformation occurring primarily in the stringers and straightening primarily to their stringers. Therefore, in the utility model discloses a skid warp orthotic devices, design left longeron supporting platform 1 and right longeron supporting platform 2 in order to support the left and right longeron of skid 100 respectively, the crossbeam 103 of skid 100 can span between left longeron supporting platform 1 and right longeron supporting platform. When the vertical deformation of the longitudinal beam is corrected, the vertical deformation can be corrected through the vertical correcting mechanism 9 between the longitudinal beam and the vertical correcting support 7. Similarly, when the lateral deformation of the side member is corrected, the correction can be performed by the lateral correction mechanism 8 between the side member and the lateral correction support (i.e., the left lateral correction support 5 or the right lateral correction support 6).

It should be noted that the deformation of skid 100 may be a vertical deformation, a lateral deformation, or both. In the use and correction process, one or more correction mechanisms can be adopted, when the correction mechanism is supported between the longitudinal beam and the transverse correction support of the skid 100, the correction mechanism is a transverse correction mechanism, and when the correction mechanism is supported between the longitudinal beam and the vertical correction support 7, the correction mechanism is a vertical correction mechanism. In this embodiment, the straightening mechanism includes a horizontal straightening mechanism and a vertical straightening mechanism, one end of the horizontal straightening mechanism is used for connecting the horizontal straightening support, and the other end of the horizontal straightening mechanism is used for applying pressure to straighten the longitudinal beam of the skid 100; one end of the vertical correcting mechanism is used for connecting the vertical correcting support 7, and the other end of the vertical correcting mechanism is used for applying pressure to correct the longitudinal beam of the skid 100. Under the condition that possess horizontal aligning gear and vertical aligning gear simultaneously, can correct the horizontal splayed deformation or vertical concave deformation synchronization that fig. 3 to 5 show simultaneously, promote and correct the operating efficiency.

The correcting mechanism can be a jack or other hydraulic pressure equipment, is easy to operate, can apply large correcting pressure to the longitudinal beam, and is high in efficiency and labor-saving compared with a manual forging mode. The utility model discloses do not specially limit to straightening mechanism's number and type.

Therefore, the skid deformation correction device is based on the correction platform and the correction mechanism, and the horizontal correction support and the vertical correction support are designed in a matched mode, so that special skid correction equipment can be formed, the structure is simple, the practicability is high, and the cost is low.

The vertical straightening support 7 serves, among other things, to provide vertical support for the vertical straightening mechanism 9 and can thus be an easily available mobile portal frame or the like. In the embodiment shown, a slide-type vertical straightening support 7 is also specifically designed. As shown in fig. 8, the vertical correcting support 7 includes an upper support platform 71 as a support of the correcting mechanism and roller columns 72, the roller columns 72 extend downward from both sides of the upper support platform 71 and are connected to the correcting platform in a rolling manner at the bottom ends. Thus, the left longitudinal beam supporting platform 1 and the right longitudinal beam supporting platform 2 can be associated through the vertical correcting support 7 shown in fig. 8, and the vertical correcting support 7 can be slidably connected to the correcting platform through the roller 73 at the bottom end, in other words, the vertical correcting support 7 can move along the longitudinal direction of the longitudinal beam, so that vertical correcting operation can be conveniently carried out on each position of the longitudinal beam. The vertical correcting support 7 of the embodiment has a simple and practical structure, and is tightly combined with the body of the correcting device, so that the device is integrally more compact and complete in function.

To achieve the sliding connection of the vertical correcting support 7 and the correcting platform, in the embodiment shown in fig. 6, the skid-deforming correcting device further comprises:

the side guide rail extends along the longitudinal direction and is provided with a side guide rail groove 10 with a transverse side opening, and the side guide rail comprises a left side guide rail 3 fixedly arranged on the transverse outer side of the left longitudinal beam supporting platform 1 and a right side guide rail 4 fixedly arranged on the transverse outer side of the right longitudinal beam supporting platform 2; and

and the roller 73 is connected with the bottom end of the roller upright 72 and is embedded in the side guide rail groove 10 in a sliding fit manner.

Wherein, left side guide rail 3 and right side guide rail 4 can weld on the both sides lateral wall of correcting the platform, behind the side guide rail groove 10 of gyro wheel 73 embedding side guide rail, not only can slide along fore-and-aft side guide rail groove 10, and when vertical correction mechanism 9 operation, vertical correction mechanism 9 acts on exerting pressure on the longeron will produce the reaction force, the reaction force acts on top supporting platform 71, then through gyro wheel stand 72, gyro wheel 73, the side guide rail conducts to the correction platform of fixed setting, therefore can provide reliable and stable vertical support. And the sliding connection structure of the side guide rail groove and the roller has the advantages of simple structure, difficult jamming, simpler processing mode and strong bearing capacity.

The side rail here has a side rail groove 10 that is laterally open, but this is merely an example. Alternatively, a guide rail groove can be pre-processed directly in the correction platform, a longitudinal slit with an upward opening is formed in the top wall of the guide rail groove, when the vertical correction support 7 slides longitudinally, the roller upright 72 moves without being blocked through the longitudinal slit of the guide rail groove, and through size design, the roller 73 can move in the guide rail groove but cannot be separated from the longitudinal slit of the guide rail groove. In other words, the reaction force generated by the pressure exerted by the vertical straightening mechanism 9 on the longitudinal beam will be finally transmitted to the top wall of the prefabricated rail groove.

For convenient for material collection and reduce cost, left longeron supporting platform 1 and right longeron supporting platform 2 all can adopt flat girder, and left longeron supporting platform 1 and right longeron supporting platform 2 all can be equipped with a plurality of platform landing legs 11 that stretch out downwards, and a plurality of platform landing legs 11 are arranged along longitudinal separation, and then platform landing leg 11 still accessible rag bolt etc. and ground fixed connection. Similarly, the left side rail 3 and the right side rail 4 shown in fig. 6 may also be conveniently made of square channel steel with open side.

As shown in fig. 6 and 7, the left transverse straightening support 5 and the right transverse straightening support 6 can both adopt right angle steel, one right angle side wall of the right angle steel is conveniently welded on the straightening platform, the other right angle side wall is used as a stress side wall bearing the pressure of the transverse straightening mechanism 8, and a reinforcing rib is arranged between the two right angle side walls. The right-angle steel can be a section, and can also have the same length as the longitudinal beam, namely, the right-angle steel continuously extends along the longitudinal beam. In particular, in the illustrated embodiment, the transverse edge portions of the two longitudinal ends of the straightening platform are oppositely distributed with a transverse straightening support 5 and a right transverse straightening support 6, so as to reserve a transverse space for placing a transverse straightening mechanism 8 and to facilitate the straightening operation on the end portions of the longitudinal beams in the longitudinal direction.

Similarly, the transverse straightening support is not limited to the right-angle steel structure shown in the figure, and can be a welded seat body with various shapes and structures, and can be designed according to the requirement. The upper support platform 71 of the vertical straightening support 7 is not limited to the illustrated lattice frame, and may be a flat plate or a truss structure.

In order to facilitate the vertical straightening operation of the skid 100, the skid deformation straightening device may further include a skid jacking mechanism 12, and the skid jacking mechanism 12 is disposed below the straightening platform and used for jacking the skid 100.

As shown in fig. 9, the skid lift mechanism 12 of this embodiment includes:

a jacking support 121;

a support plate 123 parallel to the stringers of skid 100 and arranged between left stringer 101 and right stringer 102; and

and the driving structure is supported between the jacking support 121 and the support flat plate 123.

When necessary, the skid jacking mechanism 12 can jack the skid 100 to be corrected upwards from the lower part of the correcting platform, and then a cushion block 13 can be arranged between the longitudinal beam and the flat table surface of the correcting platform in a cushioning mode, as shown in fig. 10. Like this, the cushion 13 of pad at the longeron middle part can play the effect of lever fulcrum, and vertical aligning gear 9 is when acting on longeron all tip, can be more laborsaving, the correction of exerting pressure more fast.

It will be appreciated by those skilled in the art that the driving structure of the skid lift mechanism 12 may be at least one of a pneumatic cylinder, a hydraulic cylinder, an eccentric elevating structure, and a jack. The illustrated embodiment employs a jack 122 that is more easily manipulated and adjusted by a person, with a jack adjustment rod 124 that adjusts the jack height for more labor-saving and easier manipulation.

In this way, as shown in fig. 6, the height of the jacking jack 122 can be adjusted by manually operating the jacking jack adjusting rod 124, and then the cross beams 103 of the skid 100 are supported by the supporting plate 123, so as to stably lift the skid 100.

In addition, after skid 100 is straightened by the straightening mechanism, it is necessary to detect to test whether skid 100 has been straightened. In the embodiment shown in fig. 1 and 2, skid 100 is a truss structure, and includes a left longitudinal beam 101, a right longitudinal beam 102, and a plurality of cross beams 104 connecting the two, and four workpiece support pins 104 for positioning a workpiece. When the positions and orientations of the four workpiece support pins 104 are accurate, the skid 100 is acceptable. As will be appreciated by those skilled in the art, skid 100 may be conveniently placed on the leveling platform, left stringer support platform 1 and right stringer support platform 2 have respective flat decks, and when the stringers are closely attached to the flat decks everywhere by vertical leveling mechanism 9, it is apparent that vertical deformation of the stringers is both corrected and detected. Therefore, the skid correction detection device can be independently arranged and also can be integrated in the skid deformation correction device.

As shown in fig. 11 and 12, in one embodiment, the skid deformity correction device further includes:

a detection positioning block 14 which is provided on the leveling platform and used for stopping the longitudinal end of the longitudinal beam of the skid 100;

the rectification detection mechanism 15 includes:

the detection bracket comprises a vertical bracket 151 fixedly arranged and a transverse bracket 152 pivotally connected with the top end of the vertical bracket 151;

and a sensing sleeve 153 vertically downwardly extending from the lateral bracket 152 and adapted to be fitted over the workpiece support pin 104 of the skid 100.

The detection positioning block 14 is disposed at a preset skid detection positioning position, as shown in fig. 12, the detection positioning block 14 is used for blocking an end of the longitudinal beam, so that the skid 100 is positioned at the skid detection positioning position. Each of the leveling detection mechanisms 15 is mounted in advance at a plurality of detection positions based on the sled detection positioning position. After the corrected skid 100 is positioned at the skid detection and positioning position, the detection sleeve 153 of each correction detection mechanism 15 can be sleeved outside the corresponding workpiece support pin 104, indicating that the position, orientation and direction of the workpiece support pin 104 of the skid 100 are accurate, and the correction is completed.

The correction detection means is not limited to the correction detection means 15 with the detection sleeve 153 shown in the drawing, and may be a plurality of position detection devices arranged at intervals in sequence along the side member, for example, and can detect the lateral position, the vertical position, and the like of each position, which is not illustrated here.

It should be noted that skid 100 in the illustrated embodiment includes four workpiece support pins 104, but the present invention is not limited thereto, and may include more. Similarly, it can be understood by those skilled in the art that, in order to accurately determine whether the corrected skid 100 is qualified, all four workpiece support pins 104 of the skid 100 should be detected by the correction detection mechanism 15, and therefore four sets of correction detection mechanisms 15 are disposed on the correction platform, which are aligned with the four workpiece support pins 104 of the skid 100 one by one. However, in a case where there are more workpiece support pins 104, the same number of correction detection mechanisms 15 may be provided. Of course, under the condition of having more workpiece supporting pins 104, four sets of correction detection mechanisms 15 arranged at the two longitudinal ends of the skid can meet the detection requirement.

In the illustrated orthotic detection mechanism 15, the detection brace further comprises:

a pivot positioning pin hole formed at the top end of the vertical bracket 151; and

a pivot pin 154 for insertion into the pivot pin hole to lock the lateral bracket 152 to the lateral outside of the orthotic platform.

As shown in fig. 12, when the pivot positioning pin 154 is pulled out of the pivot positioning pin hole when the detection is required, the transverse bracket 152 pivots freely and can pivot above the workpiece supporting pin 104 to be precisely sleeved with the workpiece supporting pin 104. In the non-inspection state, the straightening inspection mechanism 15 should not interfere with the straightening work, so the lateral bracket 152 can be pivoted to the lateral outside of the straightening platform, and the pivot pin 154 can be inserted into the pivot pin hole to lock the pivot, as shown in fig. 13.

The illustrated skid deformity correction devices are described in detail above. Furthermore, the utility model also provides a skid warp correction method.

Referring to fig. 14, in one embodiment, a method of skid deformation correction includes:

placing a skid 100 to be corrected on a correction platform of the skid deformation correction device according to the utility model;

according to the deformation mode of skid 100 to be corrected, correction mechanisms are respectively arranged between the longitudinal beam and the transverse correction support and/or between the longitudinal beam and the vertical correction support 7 of skid 100 to apply pressure for correction.

On the correction platform shown in fig. 6, the skid 100 can be conveniently arranged between the left longitudinal beam supporting platform 1 and the right longitudinal beam supporting platform 2 in a straddling manner and stably supported, and the arrangement posture and the arrangement stability of the longitudinal beams on the correction platform cannot be influenced by the deformation of the cross beam 103. After the stable placement, a transverse correction mechanism or a vertical correction mechanism is arranged at the position of the longitudinal beam to be corrected, and the correction supports are correspondingly adjusted and operated, so that the correction mechanism can be operated to correct. The correcting operation can be simply and easily completed only by moving the positions of a plurality of correcting supports and further operating the correcting mechanisms such as the jacks.

Skid 100 generally has a plurality of deformation modes, which are generally a splay deformation shown in fig. 3, a concave-down deformation shown in fig. 4, a concave-up deformation shown in fig. 5, and the like, according to different shapes after deformation. Since skid 100 is generally a truss structure, only the stringers of skid 100 may be straightened.

Specifically, when the stringer of the skid 100 to be corrected is deformed like a Chinese character 'ba', the flared end of the stringer can be moved to (i.e., the lower end of the stringer of the skid 100 of fig. 3) to be transversely aligned with the transverse correction support, and then the flared end of the stringer is pressed transversely inwards by the transverse correction mechanism 8, so that the transverse width of the flared end becomes smaller, and accordingly, the transverse width of the narrow-mouth end at the other end also gradually returns to be larger, and when the left stringer 101 is flush with the right stringer 102, the transverse correction can be completed.

Similarly, when the longitudinal beam of the skid 100 to be corrected is deformed in a concave manner or in a concave manner, the vertical correcting support 7 can be moved to a position right above the longitudinal beam, and the vertical correcting mechanism 9 can be used for vertically and downwardly pressing the correcting longitudinal beam until the longitudinal beam is flush with the correcting platform, so that the vertical correction can be completed.

In the specific operation, because the longitudinal beam is large in size and the pressure applied by the correcting mechanism is large, the correcting mechanism such as a jack needs to be jacked to a certain position and kept for a period of time, and then whether the correction is in place or not is detected. And the skid 100 has large size and stress, is not easy to finish correction at one time, and needs to finish correction and detection repeatedly for many times step by step.

In particular, when correcting the upper concave deformation or the lower concave deformation, if the amount of deformation is small, the pressure to be provided by the correction mechanism is larger, and the correction of the deformation is less likely to be completed. For this reason, as shown in fig. 10, when the skid deformation correcting device further includes a skid jacking mechanism 12 and a cushion block 13, the skid deformation correcting method may further include:

when the longitudinal beam of the skid 100 to be corrected is deformed in an upward concave manner or a downward concave manner, the skid 100 is upwards supported by the skid jacking mechanism 12, the cushion block 13 is arranged between the longitudinal beam and the correction platform in a cushioning manner, and then the correction mechanism vertically extrudes and corrects the longitudinal beam downwards.

In this way, the vertical correcting mechanism 9 can correct the longitudinal beam more easily through the fulcrum effect formed by the cushion block 13, and is more time-saving and labor-saving.

Further, the utility model discloses a skid warp correction method and has still integrated the detection step after correcting, and skid warp correction method promptly still includes:

positioning a skid detection positioning position and N detection positions corresponding to N workpiece supporting pins 104 of the female skid one by one on the correction platform by using the skid 100 without any deformation as the female skid (namely a standard qualified piece), and respectively presetting correction detection mechanisms 15 for detecting the positions of the workpiece supporting pins 104 on the N detection positions;

moving the skid 100 after the correction operation to a skid detection and positioning position;

n workpiece support pins 104 of the skid 100 are detected by N correction detection mechanisms 15;

when the positions of the N workpiece support pins 104 are detected as being acceptable, the correction of the skid 100 is acceptable.

Wherein N is an integer of not less than 4.

In one embodiment, referring to fig. 11 to 13, the post-correction detection step includes positioning a sled detection positioning position for placing the detection positioning block 14 on the correction platform by using a mother sled in advance, and installing four detection positions of the correction detection mechanism 15 according to the one-to-one arrangement of the four workpiece supporting pins 104 of the mother sled. After the detection positioning block 14 and the four correction detection mechanisms 15 are arranged on the correction platform, during correction operation, the transverse support 152 of the correction detection mechanism 15 is pivoted to the transverse outer side of the correction platform to prevent mechanical interference, and when detection is completed during correction, the pivoting positioning pin 154 is pulled out, and the transverse support 152 drives the detection sleeve 153 to horizontally pivot so as to test whether the detection sleeve 153 can be completely sleeved outside the corresponding nearby workpiece supporting pin 104. By alternately performing the correcting step and the post-correcting detecting step, the ideal corrected skid 100 can be finally obtained, and the skid correcting and detecting operation can be completed.

The utility model discloses in, through reasonable in design's functional unit and mechanical structure, can be with the help of jack etc. in order to produce great mechanical force, warp to the skid and carry out high-efficient correction, the effect is obvious, has also reduced safety risk and intensity of labour when artifical use the hammer. On the same correcting platform, the correcting work of various deformations can be realized. Simultaneously, combine design skid climbing mechanism, can realize the jacking of single skid, conveniently place the cushion between the longeron of skid and correction platform, increase the correction effect of skid bending deformation.

In addition, the jacks for correction at each position can have different specifications according to requirements, and other pressure equipment such as an air cylinder, a hydraulic cylinder, an eccentric lifting structure and the like can also be adopted; the overall appearance structure of the slide deformity correction device is not limited to the illustrated form. In a word, the utility model discloses it is as an organic whole with the detection to have integrateed correct, can better, faster, realize the accurate correction of skid more laborsavingly.
