In order to make the objects, technical solutions and advantages of the present invention clearer, the present invention is further described in detail by referring to the following embodiments.

The controller 3 is in signal connection with the first traveling mechanism 24, the lifting mechanism 27 and the second traveling mechanism 26, and is configured to control the traveling speeds of the first traveling mechanism 24 and the second traveling mechanism 26 and move them in opposite directions during the process of turning the target turning body 1, and to control the lifting speed or lowering speed of the lifting mechanism 27 so as to turn the target turning body 1 up and down.
Exemplarily, as shown in fig. 1, when the above-mentioned target turning body 1 is a frequency converter box on a high-speed rail, two opposite sides facing constantly during the turning process of the frequency converter box are respectively provided with one connecting rod 11 at two ends thereof, and the connecting rods 11 are arranged perpendicular to the sides facing constantly, and the two connecting rods 11 on one side face respectively face the two connecting rods 11 on the other side face. Accordingly, as shown in fig. 2, the upender may comprise a pair of hangers 22 and a pair of supports 23, wherein the other end of each hanger 22 is adapted to be respectively hooked to one of two opposite connecting rods 11 on two opposite sides of the target upender 1, and the other end of each support 23 is adapted to be respectively connected to one of the other opposite connecting rods 11 on two opposite sides of the target upender 1. Wherein each hanger 22 can be lifted by a separate lifting mechanism 27, which is kept running synchronously, or by the same lifting mechanism 27. Furthermore, for other kinds of target turning bodies 1, the connecting rods 11 may also be arranged on the side parallel to the connecting rods 11 while being perpendicular to the two opposite sides with unchanged orientation, i.e. when the target turning body 1 is turned to the vertical position, the two connecting rods 11 are at the top and bottom, respectively.
Illustratively, before the target overturning body 1 is overturned, the target overturning body 1 is horizontally placed with the bottom facing downwards, a hanging piece 22 and a supporting piece 23 on the overturning machine are respectively connected with connecting rods 11 at two opposite ends of the target overturning body 1, after the target overturning body 1 starts to be overturned, the overturning machine slowly lifts one end of the target overturning body 1 by using a lifting mechanism 27, simultaneously rotates the target overturning body 1 to a vertical position under the driving action of a first walking mechanism 24 and a second walking mechanism 26, then the first walking mechanism 24 and the second walking mechanism 26 continuously keep the original running direction, and simultaneously slowly lowers the corresponding end of the target overturning body 1 by using the lifting mechanism 27, so that the target overturning body 1 can be overturned to the position with the bottom facing upwards.
Regarding the way the suspension 22 and the support 23 are connected to the connecting bar 11 on the target turning body 1, in a preferred embodiment the machine further comprises: a U-shaped hook having an open end connected to the other end of the hanger 22 and an opening for a connection rod 11 to enter and an inner bottom wall for supporting a connection rod 11, and a U-shaped holder 231, for example, one end of the hanger 22 may have two parallel ropes connected to the through holes of both sides of the open end of the U-shaped hook. As shown in fig. 3, the U-shaped holder 231 has a bottom wall on one side facing away from the open end thereof connected to the other end of the support 23, and has an opening 2311 for one of the tie bars 11 to enter and an inner bottom wall for supporting one of the tie bars 11.
Illustratively, before turning the target turning body 1, the first traveling mechanism 24, the second traveling mechanism 26, the lifting mechanism 27, and the jacking mechanism 25 may be controlled by the controller 3 to move the U-shaped hook and the U-shaped holder 231 below the connecting rods 11 at opposite ends of the target turning body 1, respectively, to lift the hanger 22 and the support 23 by controlling the lifting mechanism 27 and the jacking mechanism 25 to lift the U-shaped hook to be hung on the connecting rod 11 of the target turning body 1, and to abut the U-shaped holder 231 on the connecting rod 11 of the target turning body 1, respectively, thereby achieving connection of the hanger 22 and the support 23 to the target turning body 1. Further, after the target turning body 1 is turned, the U-shaped hook and the U-shaped holder 231 can be detached from the target turning body 1 by controlling the lifting mechanism 27 and the jacking mechanism 25. Therefore, the connection and disconnection process of the target overturning body 1 and the overturning machine can be more convenient by arranging the U-shaped hook and the U-shaped support 231.
In a preferred embodiment of the tilter according to the above embodiment, the inner wall of the U-shaped hook is provided with a stop wall on each of its two sides along its extension to form a stop groove for the bearing to be clamped in, so that the connecting rod 11 can be supported in the stop groove by at least one bearing. With continued reference to fig. 3, the inner wall of the U-shaped holder 231 is provided with a stopper wall at both sides thereof in the extending direction thereof, respectively, to form a stopper groove in which the bearing 2312 is caught, so that the connecting rod 11 can be supported in the stopper groove by at least one bearing 2312.
Illustratively, the connecting shafts on the target turning body 1 may be prismatic or cylindrical and may each be connected with a bearing 2312. The connecting shaft on the target overturning body 1 is matched with the U-shaped hook or the limiting groove of the U-shaped support 231 through the bearing 2312, so that the axial displacement of the target overturning body 1 along the connecting rod 11 in the overturning process of the target overturning body 1 is avoided, and the stability of the overturning process of the target overturning body 1 is improved. Meanwhile, the connecting rod 11 on the target overturning body 1 can be more convenient to rotate relative to the U-shaped hook and the U-shaped support 231 through the matching of the limiting grooves of the U-shaped hook and the U-shaped support 231 and the bearing 2312, and the stability of the overturning process of the target overturning body 1 can be further improved. For example, two or three bearings 2312 can be coaxially arranged on the same connecting rod 11 to be matched with a limiting groove on a U-shaped hook or a U-shaped support 231, and the local pressure of the connecting rod 11 is reduced by increasing the bearing surface of the connecting rod, so that the overturning process of the target overturning body 1 is more stable and safer.
As shown in fig. 2, a passage 201 for the target overturning body 1 to enter and exit may be formed on one side of the frame 21, and wheels may be further disposed at the bottom of the frame 21. The frame 21 of the upender may, for example, be of steel frame construction, through which a platform truck may carry the target upender 1 in and out of the frame 21 via the passage opening 201. In addition, when the frame 21 needs to be moved, the wheels at the bottom of the frame can be used to facilitate the moving process.
It can be seen from the above scheme that the efficiency and the safety of the overturning process of the target overturning body 1 can be ensured by controlling the running speed and the running direction of the first running mechanism 24, the second running mechanism 26 and the lifting mechanism 27 of the overturning machine, and the automatic control of the overturning process is more facilitated. In addition, because the first traveling mechanism 24 and the second traveling mechanism 26 operate simultaneously, the space required by the overturning process can be saved, and the volume and the floor area of the overturning machine can be reduced; by adjusting the initial positions of the first and second running gear 24, 26, it is also possible to adapt to the turning of target turning bodies 1 of different lengths.
As shown in fig. 6, a tension sensor 41, a pressure sensor 42, an image capturing device 43 and a displacement sensor 44 may be connected to signal input ends of the controller 3, a first traveling mechanism 24, a jacking mechanism 25, a second traveling mechanism 26 and a lifting mechanism 27 may be connected to signal output ends of the controller 3, and the controller 3 may control the devices connected to the signal output ends according to data information acquired by the signal input ends of the controller 3, as will be described later.
In a preferred implementation of the tipper provided in the above embodiment, as shown in fig. 4, the controller 3 is further configured to: in the first stage, in the process of turning the target turning body 1 from the bottom surface downwards to the bottom surface towards the horizontal direction, the total displacement x generated by the first travelling mechanism 24 and the second travelling mechanism 26 and the distance R between the displacement y generated by the lifting mechanism 27 and the connecting rods 11 at the two opposite ends of the target turning body 1 are controlled to satisfy the following formula: (R-x) 2 +y 2 ＝R 2 . In the process, the distance between the hanger 22 and the supporting member 23 in the horizontal direction is first decreased by controlling the first traveling mechanism 24 and the second traveling mechanism 26, and the distance between the hanger 22 and the supporting member 23 in the vertical direction is first gradually increased by controlling the lifting mechanism 27 until the hanger 22 and the supporting member 23 are located at the same vertical level, that is, the target overturn body 1 is oriented horizontally from the bottom surface.
In the second stage, as shown in fig. 5, in the process of turning the target turning body 1 from the bottom surface to the horizontal direction until the bottom surface faces upward, the total displacement x generated by the first traveling mechanism 24 and the second traveling mechanism 26 and the distance R between the displacement y generated by the lifting mechanism 27 and the connecting rods 11 at the two opposite ends of the target turning body 1 are controlled to satisfy the following formula: x is the number of 2 +(R-y) 2 ＝R 2 . In this process, after the hanger 22 and the cradle 23 are located at the same vertical level, the first and second traveling mechanisms 24 and 26 are controlled so that the distance between the hanger 22 and the cradle 23 in the horizontal direction is increased in the opposite direction and the distance between the hanger 22 and the cradle 23 in the vertical direction is gradually decreased.
Wherein the horizontal and vertical displacements of the suspension member 22 and the support member 23 can be monitored by means of a displacement sensor 44, and the controller 3 is in signal connection with the displacement sensor 44, and can correct the operating states of the first and second traveling mechanisms 24 and 26 and the lifting mechanism 27 in time according to the monitoring results. In this way, when the operation of the tilter is controlled according to the above formula, the displacement of the target tilter 1 in the horizontal direction and the displacement in the vertical direction are matched with each other, the hanger 22 can be kept substantially vertical all the time, and simultaneously the pulling force on the hanger 22 and the bearing force on the bearing 23 are relatively uniform and can respectively keep half of the weight of the target tilter 1, thereby being beneficial to safely, stably and efficiently controlling the overturning process of the target tilter 1.
In order to meet the requirement of the displacement amounts of the first traveling mechanism 24, the second traveling mechanism 26, and the lifting mechanism 27, in a preferred embodiment of the tipper provided in the above embodiment, the controller 3 is further configured to: before the target overturn body 1 is overturned, a set value v of the running speed of the first travelling mechanism 24 is acquired 1 A set value v of the running speed of the second running gear 26 2 And the distance R between the two connecting rods 11 at the opposite ends of the target turning body 1; according to the above value v 1 、v 2 And R, calculating the change rate of the relative heights of the two ends of the target overturning body 1 in the overturning process of the target overturning body 1; during the process of overturning the target overturning body 1, according to the set value v 1 、v 2 The running speeds of the first running mechanism 24 and the second running mechanism 26 are controlled, and the running speed of the lifting mechanism 27 is controlled according to the calculated rate of change of the relative heights of both ends of the target turning body 1 to turn the target turning body 1 upside down.

In between, the rate of change of the relative heights of the two ends of the target turning body 1 is:
and, x ═ v 1 +v 2 )t，
Formula x into the second stage 2 +(R-y) 2 ＝R 2 The running time of the tilter can be properly obtained through calculus
To
In between, the rate of change of the relative heights of the two ends of the target turning body 1 is:
it should be noted that when the displacement of the target turning body 1 in the vertical direction is all generated by the lifting mechanism 27, u is described above 1 (t) and u 2 And (t) is the vertical displacement produced by the lifting mechanism 27. Although the description has been given with the operating speed of the first traveling mechanism 24 and the operating speed of the second traveling mechanism 26 as fixed values, the sum of the operating speed of the first traveling mechanism 24 and the operating speed of the second traveling mechanism 26 may be determined by a calculus method with the operating speed of the lift mechanism 27 as a fixed value. It will be appreciated that by accurately controlling the speed of operation of the first travelling mechanism 24, the second travelling mechanism 26 and the lifting mechanism 27, the process of turning the target turning body 1 by the turner can be controlled more conveniently, reliably and safely.
In a preferred implementation manner of the turnover machine provided in the foregoing embodiment, the turnover machine further includes a jacking mechanism 25, and the jacking mechanism 25 is connected to the second travelling mechanism 26 and can move along the length direction of the rack 21 under the driving of the second travelling mechanism 26; the support 23 is connected to the telescopic movable end of the jacking mechanism 25 and can be driven by the jacking mechanism 25 to lift.
The second walking mechanism 26 illustratively comprises a sliding plate which can move in a screw rod transmission manner, and specifically, a polished rod, a screw rod, a sliding plate and a motor can be arranged at the bottom of the frame, the polished rod is arranged at the bottom of the frame along the length direction of the frame, the screw rod is rotatably arranged at the bottom of the frame parallel to the polished rod, a through hole for the polished rod to pass through and a threaded hole in transmission fit with the screw rod are arranged on the sliding plate, and the motor is connected to one end of the screw rod and drives the screw rod to rotate, so that the sliding plate moves along the polished rod.
The jacking mechanism 25 may be any one of a scissor, a mast, an arm, a sleeve cylinder, and a truss. Preferably, the jacking mechanism 25 is a hydraulic lifter, and the base of the hydraulic lifter is connected to the top surface of the sliding plate, and the support 23 is connected to the movable column of the hydraulic lifter. Thus, the lifting of the support 23 can be controlled more smoothly by the hydraulic lifter. Further, the first traveling mechanism 24 is configured as a crown block movable along a horizontal guide rail at the top of the frame 21; the hoisting mechanism 27 is a rope hoist and the suspension member 22 is a retractable rope connected to the rope hoist.
In the case where the tilter further includes the jack 25, the above formula (R-x) 2 +y 2 ＝R 2 And x 2 +(R-y) 2 ＝R 2 In the drawing, x represents the total displacement amount of the first and second traveling mechanisms 24 and 26, and y represents the total displacement amount of the lift mechanism 27 and the lift mechanism 25.
Accordingly, the controller 3 is further configured to: controlling the lifting directions of the lifting mechanism 27 and the jacking mechanism 25 to be opposite and the sum of the lifting speeds to be the calculated change rate of the relative heights of the two ends of the target overturning body 1 in the process of overturning the target overturning body 1. It will be appreciated that when the displacement of the target turning body 1 in the vertical direction is brought about jointly by the lifting means 27 and the jacking means 25, u 1 (t) and u 2 And (t) is the sum of the running speeds of the lifting mechanism 27 and the jacking mechanism 25 in the reverse directions.
In a preferred embodiment of the upender provided in the above embodiment, the upender further comprises a tension sensor 41 and a pressure sensor 42, the tension sensor 41 being arranged on the hanger 22 and detecting a tension force F of the hanger 22 to the target upender 1, and the pressure sensor 42 being arranged on the support 23 and detecting a bearing force P of the support 23 to the target upender 1; the controller 3 is further configured to: acquiring the weight M of the target overturning body 1, the tension F of a hanger 22 and the supporting force P of a supporting piece 23; and corrects the traveling speeds of the first traveling mechanism 24, the second traveling mechanism 26, and the lifting mechanism 27 according to the above-mentioned values M, F and P to perform smooth turning of the target turning body 1.
For example, before the target turning body 1 is turned, the weight M of the target turning body 1 may be obtained by weighing, or the weight M of the target turning body 1 may be obtained according to the data collected by the tension sensor 41 and the pressure sensor 42. In an ideal situation, both the pulling force of the suspension 22 and the bearing force of the support 23 are half the weight of the target turning body 1.
In practical situations, by knowing the tension of the suspension member 22 on the target turning body 1 and the support force of the support member 23 on the target turning body 1 in time, when the support force and the tension are extremely uneven, for example, the suspension member 22 is inclined to cause the tension to be too large, the controller 3 can receive the stress data information fed back by the tension sensor 41 and the pressure sensor 42, and correct the operation speed of the jacking mechanism 25 and the lifting mechanism 27 according to the stress data information, so as to ensure the stability and the safety of the turning process of the target turning body 1.
Examples of controlling the running speeds of the first traveling mechanism 24, the second traveling mechanism 26, and the lifting mechanism 27 according to the above-described values M, F and P to smoothly turn the target turning body 1 include: in the process of overturning the target overturning body 1, judging whether M is more than or equal to F + P is more than or equal to F × M, wherein F is a stability coefficient obtained by experience and is more than 1; if not, the operating speed of the first running gear 24, the second running gear 26 or the lifting gear 27 is reduced so that M is less than or equal to F + P is less than or equal to F × M. In this case, the greater the turning speed of the target turning body 1 during the turning process, the lower the stability, and for target turning bodies 1 of different volumes and weights, the suitable operating speeds of the first running gear 24, the second running gear 26, the lifting gear 27 and the jacking gear 25 can be set in advance, and if the preset operating speed is not reasonable, the operating speed can be corrected during the operation of the turning body accordingly.
As another example, an example of controlling the running speeds of the first running gear 24, the second running gear 26, and the lifting gear 27 according to the above-mentioned values M, F and P to perform smooth turning of the target turning body 1 further includes: when the hanger 22 and the stay 23 are located at the same vertical level, it is judged whether or not P is satisfied>e 1 M or F<e 2 M, wherein e 1 And e 2 Is an empirical safety factor, and e 1 、e 2 <1; if not, the operating speed of the lift mechanism 27 is reduced so that it satisfies P>e 1 M or F<e 2 M. It should be noted that when the hanger 22 and the supporting member 23 are located at the same vertical level, if the pulling force of the hanger 22 is too large, the supporting force of the supporting member 23 to the target turning body 1 is reduced, and even the target turning body 1 is suspended, and at this time, the running speed of the lifting mechanism 27 is corrected by the above method, so that the stability of the target turning body 1 during the turning process can be ensured.
In a preferred implementation manner of the turning machine provided in the above embodiment, the turning machine may further include: an image acquisition device 43 configured for acquiring an image comprising the suspension 22, the support 23 and the target turning body 1; the controller 3 is further configured to control the running direction and speed of the first running mechanism 24, the second running mechanism 26 and the lifting mechanism 27 in accordance with the image acquired by the image acquisition device 43 to turn the target turning body 1 upside down.
For example, before the turning of the target turning body 1, the position of the connecting rod 11 on the target turning body 1 is determined based on the image acquired by the image acquisition device 43, and the first traveling mechanism 24, the second traveling mechanism 26 and the lifting mechanism 27 are controlled to operate so that the other ends of the hanger 22 and the supporting member 23 are located at the positions corresponding to the connecting rods 11 at both ends of the target turning body 1, respectively. The lifting mechanism 27 and the jacking mechanism 25 are used to make the U-shaped hook of the hanger 22 and the U-shaped support 231 of the support 23 below the horizontal line corresponding to the connecting rod 11 of the target overturning body 1, then the first traveling mechanism 24 and the second traveling mechanism 26 are used to move the hanger 22 and the support 23 to the positions below the connecting rod 11 respectively arranged at the two opposite ends of the target overturning body 1, and finally the lifting mechanism 27 and the jacking mechanism 25 are used to make the U-shaped hook of the hanger 22 and the U-shaped support 231 of the support 23 hung or jacked on the connecting rod 11 arranged at the two opposite ends of the target overturning body 1.
As another example, in the process of turning the target turning body 1, it is judged whether the hanger 22 and the supporting member 23 are located in the same vertical horizontal plane based on the image captured by the image capturing device 43, and the raising mechanism 27 is controlled to change the upper hanger 22 to the lower hanger 22 when the hanger 22 and the supporting member 23 are located in the same vertical horizontal plane. It should be noted that when the hanging member 22 and the supporting member 23 are located in the same vertical horizontal plane, the target turning body 1 is also rotated to the vertical position and the bottom surface thereof faces the horizontal direction, and the displacement and the stress state of the target turning body 1 are crucial for the stability and safety of the whole turning process, and in this position, the pulling force of the lifting mechanism 27 on the target turning body 1 can be controlled by adjusting the operation speed of the lifting mechanism 27, and it is also a key node for determining whether the movement directions of the lifting mechanism 27 and the lifting mechanism 25 need to be changed.

The tilter includes a frame 21 and a first traveling mechanism 24, a lifting mechanism 27 and a hanger 22 provided on the top of the frame 21, and a second traveling mechanism 26 and a support 23 provided on the bottom of the frame 21. The hanging member 22 and the supporting member 23 are respectively connected to the connecting rods 11 at the opposite ends of the target turning body 1, and in the process of turning the target turning body 1, the hanging member 22 and the supporting member 23 are moved in opposite directions in the longitudinal direction of the frame 21 by the first traveling mechanism 24 and the second traveling mechanism 26, and the relative heights of the two ends of the target turning body 1 are adjusted by the lifting mechanism 27, so that the target turning body 1 can be turned up and down efficiently and safely.
