Detailed Implementation
[0020] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0021] The following is combined with Figure 1 and Figure 2 The following describes embodiments of the present invention.
[0022] According to an embodiment of this utility model, in one aspect, a leveling and centering device for skid-mounted equipment is provided to achieve intelligent centering of the first skid body 1 and the second skid body to be spliced, so as to facilitate on-site splicing. Specifically, the leveling and centering device includes the first skid body 1 and a lifting mechanism 2, a moving mechanism 3, a positioning feedback element 4, and a controller 5 installed on the first skid body 1.
[0023] More specifically, at least a portion of the structure of the positioning feedback element 4 is mounted on the first skid 1, and at least a portion of the structure is for mounting on the second skid connected to the first skid 1. The positioning feedback element 4 is used to detect the relative position information between the first skid 1 and the second skid. The controller 5 is electrically connected to the lifting mechanism 2, the moving mechanism 3, and the positioning feedback element 4. The controller 5 is used to control the lifting mechanism 2 and the moving mechanism 3 to adjust the relative position between the first skid 1 and the second skid based on the relative position information detected by the positioning feedback element 4.
[0024] The lifting mechanism 2 is used to adjust the position of the first skid 1 in the height direction Z, and the moving mechanism 3 is used to adjust the position of the first skid 1 in the horizontal direction. Specifically, the first skid 1 has a first direction X, a second direction Y, and a height direction Z, wherein the first direction X, the second direction Y, and the height direction Z are perpendicular to each other. The lifting mechanism 2 is used to adjust the position of the first skid 1 in the height direction Z. In some cases, the second skid is arranged adjacent to and connected to one end of the first skid 1 along the first direction X. In this case, the moving mechanism 3 is used to adjust the position of the first skid 1 in the second direction Y.
[0025] In this embodiment, by integrating the lifting mechanism 2, the moving mechanism 3, and the positioning feedback element 4, and combining the automatic control of the controller 5, the precise adjustment of the skid's spatial position is achieved. This solves the problems of large positioning errors and difficult docking caused by the reliance on manual operation in traditional hoisting processes. It provides an automated centering basis for the on-site assembly of skid-mounted equipment, reduces the difficulty of on-site assembly, improves work efficiency, and saves labor costs.
[0026] Furthermore, in some embodiments, the positioning feedback element 4 includes an optical emitting element 41 and an optical receiving element 42. The optical emitting element 41 is mounted on the first pry bar 1, and the optical receiving element 42 is mounted on the second pry bar, located at a position on the second pry bar corresponding to the optical emitting element 41. In this embodiment, using the optical emitting element 41 and the optical receiving element 42 as the positioning feedback element 4 utilizes the high-precision detection characteristics of optical signals, avoiding errors from manual observation, and significantly improving the detection accuracy of the relative position between the first pry bar 1 and the second pry bar, providing a reliable basis for subsequent precise alignment.
[0027] As an alternative embodiment, the positioning feedback element 4 may also include an optical emitting element 41, an optical receiving element 42, and an optical reflecting element 42, with the optical emitting element 41 and the optical receiving element 42 mounted on the first skid body 1 and the optical reflecting element 42 mounted on the second skid body.
[0028] As an alternative embodiment, the positioning feedback element 4 may also include an ultrasonic transmitting element and an ultrasonic receiving element. The ultrasonic transmitting element is mounted on the first skid 1, and the ultrasonic receiving element is mounted on the second skid and located at a position on the second skid corresponding to the ultrasonic transmitting element.
[0029] Understandably, the positioning feedback element 4 of this utility model can also adopt other structures, as long as it can detect the relative position information of the first pry bar 1 and the second pry bar, so that the controller 5 can use the corresponding position information to realize the centering function of the pry bar.
[0030] More specifically, in some embodiments, the first pry bar 1 and the second pry bar are arranged adjacent to each other in the first direction X. The positioning feedback element 4 includes the aforementioned optical emitting element 41 and optical receiving element 42. The optical emitting element 41 is mounted on the first pry bar 1, and the optical receiving element 42 is mounted on the second pry bar and located at the position on the second pry bar corresponding to the optical emitting element 41. The optical emitting element 41 is used to emit optical signals to the optical receiving element 42, and the optical receiving element 42 is used to acquire the positional error between the optical emitting element 41 and the optical receiving element 42 in the second direction Y and / or the height direction Z. It should be noted that since the optical emitting element 41 is mounted on the first pry bar 1 and the optical receiving element 42 is mounted on the second pry bar, the positional error between the optical emitting element 41 and the optical receiving element 42 is also the positional error between the first pry bar 1 and the second pry bar, which is the aforementioned relative positional information between the first pry bar 1 and the second pry bar.
[0031] In this embodiment, by using optical elements to detect the position errors in the second direction Y and the height direction Z between the first pry bar 1 and the second pry bar arranged adjacent to each other in the first direction X, multi-dimensional (horizontal and vertical) position feedback is achieved, ensuring that the centering process covers the key directions, avoiding secondary offset caused by single-direction adjustment, and improving the overall centering reliability.
[0032] Furthermore, in some embodiments, when the positional error between the optical emitting element 41 and the optical receiving element 42 in the second direction Y is between -1mm and 1mm, the controller 5 controls the moving mechanism 3 to stop operating. In this embodiment, a positional error threshold (±1mm) between the optical emitting element 41 and the optical receiving element 42 in the second direction Y is set. When the error reaches the allowable range, the adjustment automatically stops, avoiding over-adjustment or under-adjustment, ensuring that the alignment accuracy meets the connection requirements, and improving the adjustment efficiency.
[0033] In some embodiments, when the positional error between the optical emitting element 41 and the optical receiving element 42 in the height direction Z is between -1mm and 1mm, the controller 5 controls the lifting mechanism 2 to stop operating. In this embodiment, a positional error threshold (±1mm) between the optical emitting element 41 and the optical receiving element 42 in the height direction Z is set. When the error reaches the allowable range, the adjustment automatically stops, avoiding over-adjustment or under-adjustment, ensuring that the alignment accuracy meets the connection requirements, and improving the adjustment efficiency.
[0034] For example, the optical emitting element 41 can be a laser emitter, and the optical receiving element 42 can be a laser receiver.
[0035] Furthermore, in some embodiments, the first skid body 1 is provided with a connector 6, which is used to connect to the second skid body. The connector 6 has a first connecting hole 61, and the optical emitting element 41 and the optical receiving element 42 are respectively located on opposite sides of the first connecting hole 61. In this embodiment, by arranging the optical emitting element 41 and the optical receiving element 42 on opposite sides of the first connecting hole 61 of the connector 6, the position of the connecting hole on the connector 6 is indirectly aligned by associating the optical signal with the position of the first connecting hole 61. This avoids the operational complexity caused by directly adjusting the connecting hole, and facilitates the rapid connection of the connector 6 and the second skid body using fasteners such as bolts, further improving assembly efficiency. For example, the connector 6 can be a connecting flange, a connecting plate, etc.
[0036] For example, the connector 6 is connected to one end of the first pry bar 1 along the first direction X, such as by bolting, welding, or integral molding. The connector 6 has a plate-like structure, and an ear protrudes from the top of the connector 6, on which the first connecting hole 61 is provided. In the height direction Z, the ear protrudes from the top of the first pry bar 1. The optical emitting element 41 is mounted on the top of the first pry bar 1 and is disposed opposite to the first connecting hole 61.
[0037] For example, the connector 6 can be provided as one, two, three or more. The positioning feedback element 4 can also be provided as one set, two sets, three sets or more; preferably, one set is provided to reduce costs. When the positioning feedback element 4 is provided as one set, it only needs to correspond to the first connection hole 61 of one of the connectors 6.
[0038] Understandably, the connector 6 may also be provided with at least one second connecting hole, which may be provided on the main structure of the connector 6 other than the ear, or it may be provided on the ear.
[0039] Furthermore, in some embodiments, the moving mechanism 3 includes a drive member 31 and a horizontal moving member 32. The drive member 31 is electrically connected to the controller 5, and the drive end of the drive member 31 is connected to the horizontal moving member 32. The drive member 31 is used to drive the horizontal moving member 32 to move in the second direction Y. In this embodiment, the moving mechanism 3 adopts a combined design of the drive member 31 and the horizontal moving member 32. Through the independent control of the horizontal moving member 32 by the drive member 31, precise displacement adjustment in the second direction Y is achieved, enhancing the controllability of horizontal movement and providing an execution basis for the horizontal centering of the skid.
[0040] In some embodiments, multiple sets of moving mechanisms 3 are provided, and these multiple sets of moving mechanisms 3 are relatively independently arranged on the first skid 1. In this embodiment, the multiple sets of moving mechanisms 3 are independently arranged on the first skid 1, which improves the stability of the horizontal movement of the skid through distributed adjustment, avoids the tilting or uneven force of the skid caused by single-point adjustment, and ensures the uniformity and stability of the horizontal alignment process.
[0041] For example, the first pry bar 1 has a rectangular frame structure, and the moving mechanism 3 can be disposed at the bottom of the first pry bar 1. For example, four sets of moving mechanisms 3 are disposed at intervals and symmetrically at the bottom of the first pry bar 1.
[0042] For example, the driving component 31 can be a drive motor, hydraulic cylinder, air cylinder, electric telescopic rod, etc.; the horizontal moving component 32 can be a wheeled walking mechanism such as a roller.
[0043] As an alternative embodiment, the moving mechanism 3 can also adopt a transmission structure of motor and lead screw, or a hydraulic rod and slide structure, as long as it can realize the horizontal movement function of the first skid 1.
[0044] In some embodiments, multiple sets of lifting mechanisms 2 are provided, and these multiple sets of lifting mechanisms 2 are relatively independently arranged on the first skid body 1. In this embodiment, the multiple sets of lifting mechanisms 2 are independently arranged on the first skid body 1, and the height of the skid body is precisely adjusted by lifting in sections, avoiding local overload or adjustment lag caused by overall lifting, and ensuring the precision of vertical alignment and the maintenance of the skid body's levelness.
[0045] For example, the first skid body 1 has a rectangular frame structure. There are four sets of lifting mechanisms 2, which are respectively located at the four corners of the rectangular structure of the first skid body 1.
[0046] For example, the lifting mechanism 2 can be a hydraulic cylinder, a pneumatic cylinder, an electric telescopic rod, etc.
[0047] In some embodiments, the leveling and centering device further includes an angle detection element 7, which is installed on the first skid 1 and electrically connected to the controller 5. The angle detection element 7 is used to detect the angle information of the first skid 1, and the controller 5 is used to control the lifting mechanism 2 to adjust the levelness of the first skid 1 based on the angle information detected by the angle detection element 7. In this embodiment, by monitoring the levelness of the skid in real time through the angle detection element 7, combined with the closed-loop control of the lifting mechanism 2 by the controller 5, the dynamic adjustment of the levelness of the skid is realized, thus achieving the leveling function; at the same time, centering in the height direction Z between the skids after leveling can further improve the centering efficiency and centering accuracy.
[0048] For example, the angle detection element 7 can be a tilt sensor, a fiber optic gyroscope, an inertial measurement unit, etc. For example, the angle detection element 7 can be disposed on the top of the first skid body 1. For example, multiple angle detection elements 7 can be disposed at intervals.
[0049] The leveling and centering process of the leveling and centering device of this utility model is as follows:
[0050] 1. Place the first pry bar 1 on the ground, and place the second pry bar on one side of the first pry bar 1 along the first direction X;
[0051] 2. The controller 5 controls the moving mechanism 3 to adjust the position of the first pry bar 1 in the second direction Y based on the position information of the optical emitting element 41 and the optical receiving element 42 in the second direction Y; when the position error between the optical emitting element 41 and the optical receiving element 42 in the second direction Y is between -1mm and 1mm, the controller 5 controls the moving mechanism 3 to stop moving.
[0052] 3. The controller 5 controls the lifting mechanism 2 to adjust the level of the first skid 1 based on the angle information detected by the angle detection element 7, so that the first skid 1 is in a horizontal state.
[0053] 4. The controller 5 controls the lifting mechanism 2 to adjust the position of the first skid 1 in the height direction Z according to the position information of the optical emitting element 41 and the optical receiving element 42 in the height direction Z; when the position error between the optical emitting element 41 and the optical receiving element 42 in the height direction Z is between -1mm and 1mm, the controller 5 controls the lifting mechanism 2 to stop operating.
[0054] In this way, the first pry bar 1 and the second pry bar are leveled and aligned. The first pry bar 1 and the second pry bar can be fixedly connected by bolts or other fasteners, thus completing the assembly of the first pry bar 1 and the second pry bar.
[0055] According to an embodiment of the present invention, another aspect provides a skid-mounted device, which includes the aforementioned leveling and centering device and a second skid. The second skid is adjacent to and connected to the first skid 1 in a first direction X. Understandably, the side of the second skid facing the first skid 1 is also provided with a connecting structure, which is correspondingly provided and connected to the connecting member 6 of the first skid 1. The structure of the connecting structure and the connecting member 6 can be the same or different, as long as a fixed connection between the first skid 1 and the second skid can be achieved.
[0056] Preferably, the connecting structure of the second pry bar also adopts the aforementioned connector 6. The connector 6 of the second pry bar and the connector 6 of the first pry bar 1 are arranged opposite to each other in the first direction X, and the first connecting hole 61 on the second pry bar connector 6 is opposite to the first connecting hole 61 on the first pry bar 1 connector 6. At this time, the aforementioned optical emitting element 41 can be arranged correspondingly to the first connecting hole 61 on the first pry bar 1 connector 6, and the aforementioned optical receiving element 42 can be arranged correspondingly to the first connecting hole 61 on the second pry bar connector 6.
[0057] In this embodiment, the skid-mounted equipment including the above-mentioned leveling and centering device forms a complete automated assembly system through the coordinated adjustment of the first skid body 1 and the second skid body. This solves the problem of on-site assembly relying on manual operation and significantly improves the centering efficiency and reliability of the connection holes of the skid-mounted equipment.
[0058] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
