All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.

The specific meaning of the terms in this application will be understood by those of ordinary skill in the art in a specific context.

Referring to fig. 1 to 3, the present utility model discloses an alignment apparatus for an elongated structural member, comprising a pushing unit 10; the pushing unit 10 comprises two pushing pieces 11 and two pushing driving devices 12 which are in one-to-one correspondence with the two pushing pieces 11; the two pushing pieces 11 are opposite in a first direction and are arranged at intervals, and the long structural member 40 can enter between the two pushing pieces 11; any pushing piece 11 can move in a first direction to approach or separate from the other pushing piece 11, and when any pushing piece 11 moves to approach the other pushing piece 11, the long structural piece 40 can be pushed; the pushing driving device 12 is used for driving the corresponding pushing piece 11 to move.

For ease of description, referring to fig. 1, the opposite sides of the elongated structural member 40 in the length direction will be referred to hereinafter as the left and right sides of the region of the elongated structural member 40, respectively, and the opposite ends of the elongated structural member 40 in the width direction will be referred to hereinafter as the upper and lower ends of the elongated structural member 40, respectively.

On the basis of the above structure, when the alignment device for an elongated structural member is used, the width direction of the outer trolley 30 is parallel to the first direction, and the trolley 30 is moved between the two pushing members 11; thus, when the gripper of the external gantry crane lifts the long structural member 40 between the two pushing members 11, assuming that the pushing unit 10 is located at the left side of the long structural member 40, when the long structural member 40 deflects upward at the left side, the pushing unit 10 located at the upper end of the left side of the long structural member 40 is used to push the long structural member 40, specifically, the pushing driving device 12 drives the pushing member 11 to move close to the pushing member 11 opposite to the pushing member 11 in the first direction as shown by arrow a in fig. 1, at this time, the pushing member 11 pushes the long structural member 40, the pushing distance of the pushing member 11 is reasonably controlled to align the long structural member 40, and then the gripper releases the long structural member 40, so that the long structural member 40 can be accurately placed in the bearing surface of the trolley 30.

It should be noted that the point of application of the pushing member 11 to the elongated structural member 40 does not completely coincide with the axial center point of the elongated structural member 40, so as to ensure that the elongated structural member 40 is deflectable under the pushing of the pushing member 11.

The number of the pushing units 10 in the present embodiment is at least two, and the at least two pushing units 10 are sequentially arranged at intervals along a second direction; the second direction is horizontally perpendicular to the first direction, and in fig. 1, the second direction is the direction indicated by an arrow B; when in use, at least two pushing units 10 respectively correspond to two opposite sides of the long structural member 40 in the axial direction, at this time, assuming that the left side of the long structural member 40 deflects upwards, the pushing members 11 positioned at the upper end of the left side and the lower end of the right side of the bearing area are used for pushing the long structural member 40 in a pushing manner, so that the long structural member 40 is pushed in a bidirectional pushing manner, and meanwhile, the two sides are pushed together, so that the long structural member 40 can be adjusted to a position where the central axis of the long structural member 40 coincides with the central line of the bearing surface.

It should be noted that the alignment device for an elongated structural member may be used with a detector, where the detector is used to detect the offset angle of the elongated structural member 40, and the controller is used to control the operation of each pushing driving device 12 according to the detection result of the detector; specifically, the detector may be a laser detector, the laser detector detects the offset between the elongated structural member 40 and the target position, and the controller controls the pushing driving device 12 to drive the corresponding pushing member 11 to perform pushing correction on the elongated structural member 40 according to the offset.

In other embodiments, the pushing member 11 is a pushing plate, which is used to contact with the elongated structural member 40 for pushing, where the pushing plate will generate sliding friction when pushing the elongated structural member 40, and is easy to wear the surface of the elongated structural member 40.

The pushing member 11 of the present embodiment includes a mounting base 111 and a pushing ball 112 rollably disposed on the mounting base 111; the pushing ball 112 is used for pushing the elongated structural member 40; the pushing driving device 12 is used for driving the mounting seat 111 to move; in this way, in the process of rectifying deviation by pushing the long structural member 40 by using the pushing ball 112, the pushing ball 112 and the long structural member 40 roll and rub, so that the friction force on the long structural member 40 can be reduced, and the surface of the long structural member 40 is protected.

Since the elongated structural member 40 still has shake during the process of being placed in or taken out from the bearing area, in order to avoid the elongated structural member 40 from shaking and bumping into the pushing unit 10, each pushing member 11 of the embodiment is correspondingly provided with a blocking member 20, and the blocking member 20 includes two blocking portions 21 disposed on opposite sides of the corresponding pushing member 11 in a third direction; the pushing piece 11 can move to an initial position when moving in a direction away from the pushing piece 11 opposite to the pushing piece 11; when the pushing member 11 is at the initial position, the corresponding resisting portions 21 each protrude out of the pushing member 11 in the pushing direction of the pushing member 11; the third direction is horizontally perpendicular to the first direction; thus, if the elongated structural member 40 is swung and deflected, the resisting portion 21 will resist the elongated structural member 40 from directly striking the abutment 11, so that the abutment 11 can be protected, and the abutment driving device 12 in driving connection with the abutment 11 can be prevented from being damaged by striking the abutment 11.

It should be noted that the third direction is parallel to the second direction.

The resisting part 21 of the present embodiment has an elastic direction parallel to the first direction, so that when the elongated structural member 40 impacts the resisting part 21, the resisting part 21 can deform under the elastic force to realize buffering, reduce the impact force with the elongated structural member 40, and protect the elongated structural member 40.

It should be noted that, in practical application, the elasticity of the resisting portion 21 is reasonably set, so as to ensure that the resisting portion 21 is only slightly deformed in the elastic direction when being impacted, and ensure that the resisting portion 21 always protrudes out of the pushing member 11.

The resisting part 21 of the present embodiment is made of one of rubber and polyurethane, and of course, the resisting part 21 may be made of other materials, so long as the resisting part 21 has a certain elasticity.

It should be noted that the top surface of the resisting portion 21 is higher than or flush with the top surface of the pushing member 11, and the bottom surface of the resisting portion 21 is lower than or flush with the bottom surface of the pushing member 11, so as to fully protect the pushing member 11.

The pushing driving device 12 of the present embodiment may adopt a structure in which a rotary motor, a screw, and a screw nut are engaged, or a linear motor.

The pushing driving device 12 of the embodiment is a servo electric cylinder, and the servo electric cylinder can be directly purchased by the market, so that the research and development cost is saved; specifically, the servo electric cylinder is positioned at one end of the corresponding pushing piece 11 facing away from the other pushing piece 11; the screw rod of the servo electric cylinder is in transmission connection with the pushing piece 11; at this point, the elongated structural member 40 is prevented from striking the servo motor cylinder.

The pushing unit 10 of the present embodiment further includes two lifting driving devices 13 disposed in one-to-one correspondence with the two pushing members 11; the pushing piece 11 can be lifted; the lifting driving device 13 is used for driving the corresponding pushing piece 11 to lift; in this way, the lifting driving device 13 can be adopted to adjust the pushing member 11 to a proper position according to the actual outer diameter of the elongated structural member 40, and generally the pushing member 11 corresponds to the most protruding part of the elongated structural member 40 in the first direction, so that the device is suitable for the elongated structural members 40 with different outer diameters, and the application range is enlarged.

The lifting drive device 13 may be, but not limited to, a lifting cylinder, a linear motor, etc. which are commercially available.

In practical applications, the pushing driving device 12 may drive the pushing member 11 by driving the lifting driving device 13, or the lifting driving device 13 may drive the pushing member 11 by driving the pushing driving device 12.

The pushing unit 10 of the present embodiment further includes two supports 14 disposed in one-to-one correspondence with the pushing members 11; the pushing piece 11 and the pushing driving device 12 which are correspondingly arranged are arranged on the corresponding support 14; each pushing piece 11 corresponds to the support 14, and the positions of the corresponding pushing piece 11 and the pushing driving device 12 can be flexibly selected by moving the corresponding support 14.
