Detailed Description
The present invention will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present invention more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the invention.
Example 1
The present embodiment provides a self-adjusting hydraulic lifting system for engineering, which comprises a plurality of hydraulic cylinders 4 and a hydraulic control system 40, and an adjusting assembly. The hydraulic control system 40 is communicated with the hydraulic cylinders 4 and is used for controlling the expansion and contraction of each hydraulic cylinder 4; the adjustment assembly is used to adjust the spatial layout on which the individual hydraulic cylinders 4 are mounted. As shown in fig. 1, the adjusting assembly includes a base 1, a plurality of sliders 2, a plurality of adapter plates 3, and a controller 100.
As shown in fig. 2, the base 1 includes a chassis 11, a turntable 12, and an endless guide rail 13. The chassis 11 in the embodiment adopts a round chassis 11, and the turntable 12 is positioned at the center of the chassis 11; the turntable 12 is able to spin relative to the chassis 11 and is further provided with a vertically upwards directed lever 121. The annular guide rail 13 in the embodiment adopts the guide rail with the cross section in the shape of an I, the whole annular guide rail 13 is formed by splicing a plurality of sections of arc guide rails by virtue of fasteners and is connected to the chassis 11, the spliced annular guide rail 13 can be conveniently detached from the first sliding block 21 installed on the annular guide rail, and the quantity of the sliding bodies 2 and the hydraulic cylinders 4 which are installed can be flexibly adjusted according to the operation content. Specifically, the annular guide 13 is concentrically provided on the outer periphery of the turntable 12. In this embodiment, the turntable 12 is driven by a servo motor or a stepping motor. The servo motor or the stepping motor can precisely control the rotation of the turntable 12 according to the received instruction.
As shown in fig. 3, each slide 2 of the adjustment assembly is constituted by a first slide 21 and a linear actuator 22. The first slider 21 is clamped on the endless rail 13 and can move along the endless rail 13. It should be noted that: in this embodiment, the annular movement mechanism formed by the first slider 21 and the annular guide rail 13 is unpowered, the first slider 21 cannot spontaneously move on the annular guide rail 13, and the scheme of this embodiment is that the linear actuator 22 cooperates with the turntable 12 to drive the first slider 21 to move on the annular guide rail 13. The detailed working principle will be described later.
In the solution of the present embodiment, the linear actuator 22 may use a sliding screw, an air cylinder, an electric sliding table, or any other driving mechanism capable of implementing linear reciprocating motion. For example, the illustrated linear actuator 22 employs an electric slide, which is formed by a linear guide 222 and a second slider 221 that is clamped thereon. The linear guide 222 of the linear actuator 22 is horizontally mounted on the first slider 21 and extends in the radial direction of the circular guide 13. Unlike the annular movement mechanism constituted by the first slider 21 and the annular guide rail 13, the second slider 221 and the linear guide rail 222 in the present embodiment constitute a linear actuator that is capable of spontaneous movement, and the second slider 221 is capable of reciprocating on the linear guide rail 222 in the radial direction of the annular guide rail 13 according to the received instruction.
As shown in fig. 4, the adapter plate 3 is a Z-type bending plate; the adapter plates 3 are arranged along the radial direction of the annular guide rail 13, the lower step surface of the adapter plates 3 is fixed on the second sliding block 221, and the higher step surface extends outwards. The lower end part of the step surface in the adapter plate 3 is provided with a notch 31 matched with the deflector rod 121; a through hole 32 for mounting the hydraulic cylinder 4 is provided in the higher step surface. In the practical application process of the hydraulic lifting system for engineering with self-adjusting point positions, the number of the sliding bodies 2 installed on the base 1 corresponds to the number of the hydraulic cylinders 4 one by one, and each sliding body 2 is fixedly connected with one hydraulic cylinder 4 through one adapter plate 3. During installation, the hydraulic cylinder 4 is inserted into the through hole 32 at the end of the adapter plate 3 and is fixedly connected with the adapter plate 3 through a fastener. The installed hydraulic cylinder 4 is kept vertical to the plane of the chassis 11.
In particular, the hydraulic cylinder 4 in the present embodiment adopts a double-headed cylinder; the double-head cylinder is provided with a cylinder body and two telescopic rods positioned at two ends of the cylinder body; the two telescopic rods synchronously move in a telescopic way along the two sides of the cylinder body. When jacking operation is needed, the cylinder bodies in the double-head cylinder synchronously extend along the two sides so as to finish jacking. When the lifting height needs to be reduced, the two telescopic rods retract synchronously, so that the distance between the upper end and the lower end of the hydraulic cylinder 4 is reduced.
The hydraulic lifting system for engineering with self-adjusting point positions provided by the embodiment uses one controller 100 as a control center, and all electric control components are cooperatively controlled so as to flexibly adjust parameters such as supporting point positions, integral loads and the like in lifting or jacking operation. Specifically, as shown in FIG. 5, the controller 100 is electrically connected to the hydraulic control system 40, the turntable 12, and the linear actuator 22.
The application method of the hydraulic lifting system for engineering for self-adjusting point positions provided by the embodiment is as follows:
When the technician performs the equipment installation, the maximum number of hydraulic cylinders 4 participating in the work needs to be determined according to the maximum load required in the actual working process and the point position layout of all hydraulic cylinders 4 needing to be adjusted. A corresponding number of combinations of slide bodies 2 and adapter plates 3 are then pre-mounted onto the annular guide rail 13 in the base 1. Next, respectively installing corresponding hydraulic cylinders 4 into the adapter plates 3 on each sliding body 2, and finally connecting each hydraulic cylinder 4 with a hydraulic control system 40 through a hydraulic pipeline; and (3) assembling the hydraulic lifting system for engineering of the self-adjusting point position.
The hydraulic lifting system for engineering with self-adjusting point positions after assembly is embedded into the working space in the actual engineering application scene. In use, the hydraulic control system 40 pumps hydraulic oil to each hydraulic cylinder 4 through the hydraulic pipeline according to the instruction, thereby completing the lifting operation. When the number and the spatial position of the hydraulic cylinders 4 participating in the work in the hydraulic lifting system for engineering of the self-adjusting point position need to be adjusted, the controller 100 automatically generates the state adjustment strategy of each hydraulic cylinder 4 according to the difference between the point position layout of the current hydraulic cylinder 4 and the received target point position layout. Then the designated hydraulic cylinders 4 are driven to stretch and retract through the hydraulic control system 40 respectively so as to adjust the number of the hydraulic cylinders 4 participating in the operation in the hydraulic lifting system; then, the linear actuator 22 and the rotary table 12 are cooperated to adjust the included angle of the hydraulic cylinder 4 participating in the operation relative to the reference direction; finally, the distance between the hydraulic cylinder 4 participating in the operation and the center of the chassis 11 is adjusted by the linear actuator 22.
In the hydraulic lifting system for engineering with self-adjusting point positions in this embodiment, the point position layout is data of spatial positions of hydraulic cylinders 4 participating in work in the reaction operation process, for example, fig. 6 includes two different point position layout diagrams, four hydraulic cylinders A1 to D1 are distributed in square form in the upper half of fig. 6, and five hydraulic cylinders A2 to E2 are distributed in pentagon form in the lower half of fig. 6. Taking two typical point location maps in fig. 6 as an example, assuming that the upper half of fig. 6 is the distribution of hydraulic cylinders 4 in the current state and the lower half is the distribution of hydraulic cylinders 4 in the target state, the process of generating the state adjustment strategy by the controller 100 according to the two point location maps in this embodiment is as follows:
(1) Generating a polygon according to the layout of the N points;
(2) Generating an inscribed circle corresponding to the polygon;
(3) Establishing an angular coordinate system by taking the center of an inscribed circle as an origin;
(4) Generating angular coordinates (beta, r) corresponding to the point positions of the hydraulic cylinders 4 under the established angular coordinate system;
(5) Based on the angular coordinates of each position before and after adjustment, a point rearrangement path which meets the requirement of no interference and has the minimum total movement angle of each position is generated by using any path planning algorithm.
Taking fig. 6 as an example, the following features are required: in the solution of the present embodiment, all hydraulic cylinders 4 are actually preloaded into the hydraulic lifting system during the assembly of the apparatus, except that in the upper part of the point placement state of fig. 6, E1 belongs to a "virtual point" that is not involved in the operation, whereas in the lower part of the point placement state of fig. 6, after adjustment, E1 is the corresponding hydraulic cylinder 4 that is also involved in the operation. The final state adjustment strategy is: A1→A2, B1→B2, E1→C2, C1→D2, D1→E2,
The state adjustment strategy provided in this embodiment follows: and adjusting azimuth angles beta of all the point positions, and then adjusting the radius r of each point position. This is because, in the adjustment assembly of the present invention, no interference will occur after the angle adjustment is completed, no matter what adjustment is made to the radius of each point.
Fig. 6 of the present embodiment shows a typical dot placement adjustment concept, namely: any polygon can generate a circumcircle based on a plurality of points, then an angular coordinate system is established by combining the circumcircle, then the angular coordinates of each point are obtained, and an adjustment strategy is generated based on the angular coordinates of each point before and after adjustment. Although this strategy would likely cause difficulty in the generation of the adjustment strategy when the dot layout is a complex polygonal layout, the dot layout of the hydraulic cylinder 4 is typically not too complex in practical applications. For example, in most scenarios, the position of the hydraulic cylinder 4 need only be adjusted between spatial layouts that correspond to a positive N deformation. Based on this, the controller 100 of the present embodiment further presets a plurality of typical dot placement diagrams, and a switching rule table of any two dot placement diagrams; and thus support the generation of a state adjustment strategy for the hydraulic cylinder 4 by means of a look-up table.
After the adjustment strategy of the point position layout is clarified, the strategy of adjusting the number of the hydraulic cylinders 4 by the controller 100 is simpler, and when the number of the hydraulic cylinders 4 is reduced, only the hydraulic cylinders 4 which need to be withdrawn from operation are determined according to the front and rear point position layout diagrams, then the hydraulic cylinders 4 are adjusted to the non-interference position, and the hydraulic cylinders 4 are controlled to retract to a state of not contacting with the jacking object. When the number of the hydraulic cylinders 4 is increased, the hydraulic cylinders 4 in the idle state are moved to the corresponding points of the next path of the hydraulic cylinders participating in the operation according to the front and back point position layout diagrams, and then the hydraulic cylinders are controlled to extend to a state of contacting with the jacking object.
In this embodiment, the strategy of the controller 100 for adjusting the azimuth angle of any hydraulic cylinder 4 with respect to the reference direction is as follows:
First, the controller 100 needs to give a command to the hydraulic control system 40 to drive the hydraulic cylinder 4 of the present wheel adjustment to withdraw from the operation, and retract to the shortest state of not contacting the lifting object. The retraction of the hydraulic cylinder 4 to the minimum in this embodiment is on the one hand avoided during movement from contact with the lifting object and on the other hand also avoided from interference with other components of the apparatus itself, such as the chassis 11. Furthermore, special emphasis is required: in the embodiment, when the hydraulic cylinders 4 are subjected to point position adjustment in jacking operation, only one hydraulic cylinder 4 is allowed to be adjusted each time, so that the situation that when the hydraulic cylinders 4 which are out of operation are too many, the rest hydraulic cylinders 4 are damaged due to overload of load is avoided.
After the hydraulic cylinder 4 is retracted, an instruction is given to the rotary table 12, and the rotary table 12 is controlled to rotate, so that the deflector rod 121 on the rotary table 12 corresponds to the position of the adapter plate 3 on the corresponding sliding body 2. The device coordinate system of the hydraulic lifting system of this embodiment adopts angular coordinates, and the azimuth angles in the positions of the turntable 12 and the sliding body 2 are known, and the notch 31 on the adapter plate 3 can be opposite to the deflector rod 121 on the turntable 12 only by adjusting the azimuth angles to be consistent.
Next, as shown in fig. 7, the second slider 221 in the linear actuator 22 is controlled to slide toward the turntable 12, so that the notch 31 on the adapter plate 3 is engaged with the lever 121. In this embodiment, the linear actuator 22 has limited the travel of the second slider 221221 during product design and assembly installation, and ensures that the notch 31 on the adapter plate 3 can just complete the docking and jamming with the lever 121 on the turntable 12 when the second slider 221221 slides inward to the end of travel.
As shown in fig. 8, when the lever 121 is locked with the notch 31, the hydraulic cylinder 4, the adapter plate 3, the linear actuator 22, the first slider 21, and the turntable 12 essentially form a combination. At this time, the controller 100 gives an instruction to the turntable 12 to control the rotation of the combination, so as to drive the combination of the slider 2 and the hydraulic cylinder 4 to reach a preset orientation. I.e. the azimuth angle of the hydraulic cylinder 4.
Finally, after the azimuth adjustment of the hydraulic cylinder 4 is completed, the controller 100 issues a command to the linear actuator 22 to control the second slider 221 to slide to the side far away from the turntable 12, so that the shift lever 121 is disengaged from the notch 31.
In the solution of the present embodiment, after the azimuth adjustment of each hydraulic cylinder 4 is completed, the distance between the relative origins of each hydraulic cylinder 4 (i.e., the center of the turntable 12) can be adjusted. In the adjustment process, when the distance between the center of the chassis 11 and the hydraulic cylinder layout is enlarged after any hydraulic cylinder layout adjustment, the second slider 221 in the linear actuator 22 is driven to move to the side far away from the turntable 12, and conversely, to move to the side close to the turntable 12.
As can be seen from the foregoing, the second slider 221 and the linear guide 222 that implement radial movement in the adjustment assembly belong to an electric sliding table, and a self-locking structure is provided between the second slider 221 and the linear guide 222 in the electric sliding table. The annular guide rail 13 and the first slider 2121 on the chassis 11 belong to unpowered devices, and in order to ensure that the turntable 12 can slide the first slider 21 in the combined state more smoothly, a self-locking mechanism is not generally arranged between the first slider 21 and the annular guide rail 13. In order to avoid the first slider 21 after the position adjustment from sliding on the annular guide rail 13, in a more optimized scheme of this embodiment, a plurality of electric mortise locks 5 are uniformly distributed on the base 1 near the annular guide rail 13, and a lock hole is provided on the first slider 21. The electric mortise lock 5 is provided with a telescopic lock tongue, and when the first sliding block 21 is moved to a preset position, the electric mortise lock 5 stretches out the lock tongue and inserts into a lock hole on the first sliding block 21 to lock the position of the lock tongue. When the position of the hydraulic cylinder 4 needs to be continuously adjusted, the controller 100 gives an instruction to the battery mortise lock to control the lock tongue to retract, and the unlocking is completed.
In a more optimized solution of this embodiment, the base 1 is further provided with a plurality of position sensors 6; the position sensors 6 are distributed uniformly along an annular region concentric with the annular rail 13. These position sensors 6 can be used to detect the actual spatial position of the respective slide 2 during the state adjustment. Each position sensor 6 is electrically connected to the controller 100, and a detection signal of the position sensor 6 is transmitted to the controller 100 as feedback information. In addition to the position sensor 6, in a further optimized solution of the present embodiment, a micro camera may be installed along the circumference of the turntable 12 of the chassis 11, so as to obtain the states of various components, an elevating object, and the like in the working space in real time.
In the solution of the present embodiment, the controller 100 in the self-adjusting point-of-view hydraulic lifting system is essentially a computer device for implementing data processing and instruction generation, comprising a memory, a processor and a computer program stored on the memory and executable on the processor. The computer device provided in the present embodiment may be an embedded device capable of executing a computer program. The system can also be an intelligent terminal capable of executing programs, such as a tablet computer, a notebook computer, a desktop computer, a rack-mounted server, a blade server, a tower server or a cabinet server (comprising independent servers or a server cluster formed by a plurality of servers), and the like.
The computer device of the present embodiment includes at least, but is not limited to: a memory, a processor, and the like, which may be communicatively coupled to each other via a system bus. In this embodiment, the memory (i.e., readable storage medium) includes flash memory, hard disk, multimedia card, card memory (e.g., SD or DX memory, etc.), random Access Memory (RAM), static Random Access Memory (SRAM), read-only memory (ROM), electrically erasable programmable read-only memory (EEPROM), programmable read-only memory (PROM), magnetic memory, magnetic disk, optical disk, etc. In some embodiments, the memory may be an internal storage unit of a computer device, such as a hard disk or memory of the computer device.

In this embodiment, the memory is typically used to store an operating system and various application software installed on the computer device. In addition, the memory can be used to temporarily store various types of data that have been output or are to be output.
