Description

Technical Field

[0001] This utility model relates to the field of geotechnical engineering technology, and in particular to a hydraulic vibration damping adapter and a shotcrete boom lift truck. Background Technology

[0002] In the field of geotechnical engineering, slope shotcrete construction is a crucial step in ensuring slope stability and safety, and its construction safety and quality directly affect the successful achievement of the entire construction project objectives. Traditional slope shotcrete construction relies primarily on manual operation. Workers must stand on the slope or be suspended from it by safety ropes, manually securing the shotcrete pump head and spraying concrete onto the work surface. This method has many drawbacks, especially in high slope shotcrete construction. Because concrete concealment construction must be completed quickly after rock excavation to prevent weathering and deformation due to environmental factors, the inefficiency and high risk of traditional manual shotcrete construction become increasingly apparent.

[0003] With technological advancements, shotcrete boom lifts have been increasingly used in slope shotcrete construction, and their mechanized wet spraying method has improved construction efficiency to some extent. However, in actual operation, the hydraulic system of the shotcrete boom lift generates harmful vibrations. These vibrations not only reduce the lifespan of the equipment and increase the probability of mechanical failures, but also negatively impact the operational precision of workers, thus affecting construction quality. Especially when facing complex geological conditions with varying heights, slopes, and degrees of rock weathering, the presence of harmful vibrations makes it difficult for workers to complete shotcrete operations safely and efficiently, requiring significant time for relocation, increasing construction difficulty and safety risks, and potentially even impacting the overall project schedule due to safety accidents. Utility Model Content

[0004] This utility model provides a hydraulic vibration damping adapter and a shotcrete boom truck to solve the defects of harmful vibrations generated by the existing boom truck during the shotcrete operation on slopes, thereby significantly reducing harmful vibrations and greatly improving the precision of shotcrete concrete.

[0005] This utility model provides a hydraulic vibration damping adapter, comprising: shell; Multiple pins are arranged side by side inside one end of the housing. Each pin has two protruding ends that extend from opposite sides of the housing along its own axial direction. The protruding ends are used to connect to a hydraulic arm. A connecting plate, which is movably disposed within the housing, is used to connect with the spray anchor robot. Multiple hydraulic vibration dampers are provided, and each hydraulic vibration damper is correspondingly arranged with a pin. One end of each hydraulic vibration damper is connected to the connecting plate, and the other end of each hydraulic vibration damper is sleeved on the pin through a bushing. A wear-resistant nylon sleeve is placed between the bushing and the pin.

[0006] According to the present invention, a hydraulic vibration damping adapter is provided, wherein the outer shell is open at one end away from the pin, and limiting grooves are formed on the inner walls of the opposite sides of the outer shell near the open, and the connecting plate is movably installed in the limiting grooves.

[0007] According to the present invention, a hydraulic vibration damping adapter further includes a first limiting steel plate and a second limiting steel plate, wherein the first limiting steel plate and the second limiting steel plate are spaced apart on the inner wall surface of the outer shell near the opening, and the first limiting steel plate and the second limiting steel plate form a limiting groove spaced apart.

[0008] According to the present invention, a hydraulic vibration damping adapter is provided, wherein the hydraulic vibration damper includes a hydraulic rod, a hydraulic cylinder and a vibration damping spring. The bottom of the hydraulic cylinder is connected to the bushing, one end of the hydraulic rod extends into the inner cavity of the hydraulic cylinder and slides with the hydraulic cylinder, and the vibration damping spring is sleeved on the hydraulic rod and abuts against the connecting plate and the hydraulic cylinder.

[0009] According to the present invention, a hydraulic vibration damping adapter is provided, wherein the hydraulic rod is welded to the connecting plate via a pad, and the vibration damping spring abuts between the pad and the hydraulic cylinder.

[0010] According to the present invention, a hydraulic vibration damping adapter is provided in which the end of the hydraulic cylinder away from the connecting plate is welded to the outer wall of the bushing.

[0011] According to the present invention, a hydraulic vibration damping adapter is provided, wherein the connector has multiple bolt holes, and the connector plate is connected to the spray anchoring robot by fasteners passing through the bolt holes.

[0012] According to the present invention, a hydraulic vibration damping adapter is provided in which the distribution position of the plurality of bolt holes on the connecting plate is located inside the overall range formed by the corresponding connection positions of the plurality of hydraulic vibration dampers and the connecting plate.

[0013] Also provided is a spray anchor articulated boom truck, including: Chassis; Multiple hydraulic support arms are provided, and the multiple hydraulic support arms are sequentially hinged to each other, with the leading end of each hydraulic support arm hinged to the chassis. A telescopic arm, the end of which is hinged to the end of the hydraulic support arm; A hydraulic arm, which is connected to the telescopic end of the telescopic arm; A spray anchor robot is connected to the hydraulic arm via a hydraulic vibration damping adapter as described above.

[0014] According to the present invention, a spray anchor articulated boom truck also includes a pipeline system and a lifting ring structure. The lifting ring structure is fixed on the telescopic boom. One end of the pipeline system passes through the lifting ring structure and is connected to the spray anchor robot. The other end of the pipeline system is used to connect with external equipment.

[0015] This utility model provides a hydraulic vibration damping adapter and a spray anchor boom truck. The hydraulic vibration damping adapter constructs a multi-stage buffer path for vibration transmission through a one-to-one correspondence between multiple hydraulic vibration dampers and multiple pins. One end of the hydraulic vibration damper is connected to a connecting plate, and the other end is fitted onto the pin through a bushing, allowing it to directly participate in the vibration transmission chain between the spray anchor robot and the hydraulic arm. When the spray anchor robot generates vibration during operation, the hydraulic vibration damper can convert the vibration energy into the internal energy of the hydraulic oil through its own hydraulic damping characteristics, weakening the vibration intensity at the source. Simultaneously, the wear-resistant nylon sleeve between the bushing and the pin utilizes the elastic deformation capability of its polymer material to provide secondary buffering of the vibration, avoiding vibration reflection and amplification caused by rigid contact between metal parts. The synergistic damping system formed by these two components effectively blocks the transmission of vibration from the spray anchor robot to the outer shell and hydraulic arm, significantly reducing harmful vibrations in the overall equipment. Secondly, multiple pins are arranged side-by-side at one end of the housing, with their protruding ends connected to the hydraulic arm, forming a stable support reference. A connecting plate is movably mounted inside the housing and connects to the shotcrete manipulator, ensuring flexibility in adjusting the working angle while limiting unnecessary displacement through the constraint of the housing. This structure significantly reduces harmful vibrations, reducing high-frequency shaking caused by vibration during shotcreting and making the spraying trajectory more stable. Simultaneously, the hydraulic vibration damper suppresses instantaneous impact vibrations, allowing construction personnel to more precisely control the spraying point position and concrete spraying volume when operating the shotcrete manipulator via the hydraulic arm, avoiding spraying deviation caused by vibration, thereby greatly improving the accuracy of shotcrete application.

[0025] The following is combined with Figure 1 and Figure 2 The present invention provides a detailed description of a hydraulic vibration damping adapter and a spray anchor boom truck through specific embodiments and application scenarios.

[0026] In the embodiments of this utility model, such as Figure 2 As shown, a hydraulic vibration damping adapter 600 includes a housing 610, a plurality of pins 620, a connecting plate 630, and a plurality of hydraulic vibration dampers 640. The plurality of pins 620 are arranged side by side inside one end of the housing 610. Each pin 620 has two protruding ends extending from opposite sides of the housing 610 along its own axis, and the protruding ends are used to connect to a hydraulic arm 400. The connecting plate 630 is movably disposed inside the housing 610 and is used to connect to a spraying and anchoring robot 500. The plurality of hydraulic vibration dampers 640 are arranged one-to-one with the plurality of pins 620. One end of the hydraulic vibration damper 640 is connected to the connecting plate 630, and the other end of the hydraulic vibration damper 640 is sleeved on the pin 620 through a bushing 690. A wear-resistant nylon sleeve 680 is placed between the bushing 690 and the pin 620.

[0027] The outer shell 610 serves as the basic frame of the entire hydraulic vibration damping adapter 600, accommodating and protecting the pin 620, connecting plate 630, hydraulic vibration damper 640, etc., while providing an installation reference for each component, ensuring that they work together in a relatively stable space, and maintaining the integrity and stability of the overall structure of the adapter.

[0028] Multiple pins 620 are arranged side-by-side inside one end of the housing 610, with their two ends extending from opposite sides of the housing 610 along their own axial direction to form protruding ends, which are used to connect with the hydraulic arm 400. The pins 620 are components that connect the adapter and the hydraulic arm 400. The side-by-side arrangement of multiple pins 620 can distribute the connection force, improve the stability of the connection, and ensure that the power and movement transmitted by the hydraulic arm 400 can stably act on the adapter, while also providing support points for the installation of the hydraulic vibration damper 640.

[0029] The connecting plate 630 is movably disposed within the housing 610 and is used to connect with the shotcrete robot 500. The connecting plate 630 is the connection medium between the adapter and the shotcrete robot 500. Its movable nature ensures that the shotcrete robot 500 has a certain degree of angle adjustment flexibility during operation, which can adapt to different construction needs. At the same time, it can transmit the vibration generated by the shotcrete robot 500 to the hydraulic vibration damper 640 for vibration buffering.

[0030] Multiple hydraulic vibration dampers 640 are correspondingly installed with multiple pins 620, one end of which is connected to the connecting plate 630, and the other end is sleeved on the pin 620 through a bushing 690. When the spraying and anchoring robot 500 vibrates during operation, it can absorb the vibration energy by virtue of its own hydraulic damping characteristics, converting the vibration energy into the internal energy of the hydraulic oil, thereby weakening the vibration intensity and preventing the vibration from being transmitted to the hydraulic arm 400 and the outer casing 610, effectively reducing harmful vibration.

[0031] The bushing 690 is fitted onto the pin 620 and connected to the other end of the hydraulic vibration damper 640. The bushing 690 serves to connect the hydraulic vibration damper 640 and the pin 620, providing a stable installation position for the hydraulic vibration damper 640.

[0032] A wear-resistant nylon sleeve 680 is placed between the bushing 690 and the pin 620. It has good wear resistance, reducing frictional loss between the bushing 690 and the pin 620 and extending their service life. Simultaneously, the nylon material has a certain degree of elastic deformation, which can buffer vibration, assisting the hydraulic vibration damper 640 in attenuating vibration and preventing vibration reflection and amplification caused by rigid contact between the bushing 690 and the pin 620.

[0033] The hydraulic vibration damping adapter 600 of this application constructs a multi-stage buffer path for vibration transmission through a one-to-one correspondence between multiple hydraulic vibration dampers 640 and multiple pins 620. One end of the hydraulic vibration damper 640 is connected to the connecting plate 630, and the other end is fitted onto the pin 620 via a bushing 690, allowing it to directly intervene in the vibration transmission chain between the spraying and anchoring robot 500 and the hydraulic arm 400. When the spraying and anchoring robot 500 vibrates during operation, the hydraulic vibration damper 640 can convert the vibration energy into the internal energy of the hydraulic oil through its own hydraulic damping characteristics, weakening the vibration intensity at the source. Simultaneously, the wear-resistant nylon sleeve 680 between the bushing 690 and the pin 620 utilizes the elastic deformation capability of its polymer material to provide secondary buffering of the vibration, avoiding vibration reflection and amplification caused by rigid contact between metal parts. The synergistic damping system formed by these two components effectively blocks the transmission of vibration from the spraying and anchoring robot 500 to the outer shell 610 and the hydraulic arm 400, significantly reducing harmful vibrations in the overall equipment. Secondly, multiple pins 620 are arranged side-by-side at one end of the housing 610, with their protruding ends connected to the hydraulic arm 400, forming a stable support reference. The connecting plate 630 is movably disposed within the housing 610 and connected to the shotcrete manipulator 500, ensuring both the flexibility of adjusting the working angle and limiting unnecessary displacement through the constraint of the housing 610. This structure significantly reduces harmful vibrations, allowing the shotcrete manipulator 500 to reduce high-frequency shaking caused by vibration during spraying, resulting in a more stable spraying trajectory. Simultaneously, the hydraulic vibration damper 640 suppresses instantaneous impact vibrations, enabling construction personnel to more precisely control the spraying point position and concrete spraying volume when operating the shotcrete manipulator 500 via the hydraulic arm 400, avoiding spraying deviation caused by vibration, thereby greatly improving the precision of shotcrete.

[0034] Reference Figure 2 According to the present invention, a hydraulic vibration damping adapter 600 is provided, wherein the outer shell 610 is provided with an open end 611 away from the pin 620, and a limiting groove 670 is formed on the inner walls of the opposite sides of the outer shell 610 near the open end 611, and the connecting plate 630 is movably installed in the limiting groove 670.

[0035] Understandably, the open design of the housing 610 611 provides space for the installation and operation of components installed inside the housing.

[0036] The limiting groove 670 guides and constrains the movement of the connecting plate 630. On the one hand, it limits the movement trajectory of the connecting plate 630, preventing it from shifting or shaking when vibrating or under stress, thus ensuring the stability of the connection between the connecting plate 630 and the hydraulic vibration damper 640 and the shotcrete robot 500. On the other hand, the constraint of the limiting groove 670 keeps the movement range of the connecting plate 630 within a reasonable range, preventing damage to components such as the hydraulic vibration damper 640 due to excessive stress caused by excessive movement. At the same time, it ensures that the working accuracy of the shotcrete robot 500 is not affected by the abnormal displacement of the connecting plate 630, further improving the reliability of equipment operation.

[0037] Reference Figure 2 According to the present invention, a hydraulic vibration damping adapter 600 further includes a first limiting steel plate 650 and a second limiting steel plate 660. The first limiting steel plate 650 and the second limiting steel plate 660 are spaced apart and disposed on the inner wall surface of the outer shell 610 near the end of the opening 611. The first limiting steel plate 650 and the second limiting steel plate 660 form a limiting groove 670 spaced apart.

[0038] Understandably, the first limiting steel plate 650 and the second limiting steel plate 660 are spaced apart and arranged on the inner wall of the outer shell 610 near the opening 611. Their core function is to form the limiting groove 670 through their spaced distribution. As a component of the limiting groove 670, the steel plate itself has high structural strength and stability, providing reliable structural support for the limiting groove 670. This ensures that the limiting groove 670 is not easily deformed during long-term use and under external forces, guaranteeing a durable and effective limiting effect on the connecting plate 630.

[0039] The limiting groove 670 provides a clear range of motion and trajectory constraints for the connecting plate 630. The connecting plate 630 is movably installed within this limiting groove 670, which restricts the displacement of the connecting plate 630 in unnecessary directions, preventing it from shifting or swaying due to vibration, stress, or other factors. This ensures that the connecting plate 630 only moves within a preset, reasonable range. This not only helps maintain the stress stability of components such as the hydraulic vibration damper 640 and ensures the stability of the vibration transmission path, thereby improving the vibration damping effect, but also makes the movement of the shotcrete manipulator 500 more controllable, contributing to improved accuracy in shotcrete application. Simultaneously, the limiting groove 670 also facilitates the installation and positioning of the connecting plate 630, enabling quick and accurate positioning during assembly and improving assembly efficiency.

[0040] Reference Figure 2According to the present invention, a hydraulic vibration damping adapter 600 is provided, and a hydraulic vibration damper 640 includes a hydraulic rod 641, a hydraulic cylinder 642 and a vibration damping spring 643. The bottom of the hydraulic cylinder 642 is connected to the bushing 690. One end of the hydraulic rod 641 extends into the inner cavity of the hydraulic cylinder 642 and slides with the hydraulic cylinder 642. The vibration damping spring 643 is sleeved on the hydraulic rod 641 and abuts between the connecting plate 630 and the hydraulic cylinder 642.

[0041] Understandably, the bottom of the hydraulic cylinder 642 is connected to the bushing 690, and one end of the hydraulic rod 641 extends into the inner cavity of the hydraulic cylinder 642 and slides with it, forming the core unit of the hydraulic buffer. The bushing 690 is connected to the pin 620, and the hydraulic rod 641 can guide the vibration impact force transmitted by the connecting plate 630 into the interior of the hydraulic cylinder 642, realizing the conversion and consumption of vibration energy by means of the viscous resistance of the hydraulic oil. The sliding fit ensures that the hydraulic rod 641 can flexibly extend and retract with vibration, so that the hydraulic damping effect can dynamically respond to vibrations of different intensities, avoiding vibration rebound caused by rigid connection.

[0042] The vibration damping spring 643 is sleeved on the hydraulic rod 641 and abuts against the connecting plate 630 and the hydraulic cylinder 642. Its installation position allows it to directly bear the relative displacement between the connecting plate 630 and the hydraulic cylinder 642. When the spraying and anchoring robot 500 vibrates, the shaking of the connecting plate 630 will first compress or stretch the vibration damping spring 643. The spring absorbs part of the vibration energy through elastic deformation, playing a preliminary buffering role. At the same time, the hydraulic rod 641 slides along the hydraulic cylinder 642 under the combined action of the spring force and the vibration impact force, triggering hydraulic damping to further attenuate the vibration, forming a dual vibration damping mechanism of spring buffering and hydraulic damping.

[0043] Reference Figure 2 According to the present invention, a hydraulic vibration damping adapter 600 is provided, wherein a hydraulic rod 641 is welded to a connecting plate 630 via a pad 644, and a vibration damping spring 643 abuts between the pad 644 and the hydraulic cylinder 642.

[0044] Understandably, the pad 644 increases the welding contact area between the hydraulic rod 641 and the connecting plate 630, dispersing the stress at the weld point and avoiding stress concentration issues caused by the small contact area when the hydraulic rod 641 is directly welded to the connecting plate 630. This significantly improves the structural strength and durability of the connection. Under continuous vibrations generated during shotcrete operations, it ensures the stability between the hydraulic rod 641 and the connecting plate 630, preventing weld breakage due to vibration fatigue. It also ensures that vibration energy is stably transferred from the connecting plate 630 to the hydraulic rod 641, providing a reliable force transmission path for subsequent vibration damping.

[0045] In some embodiments, the end of the hydraulic cylinder 642 away from the connecting plate 630 is welded to the outer wall of the bushing 690.

[0046] Understandably, the end of the hydraulic cylinder 642 furthest from the connecting plate 630 is welded to the outer wall of the bushing 690. Utilizing the rigid connection characteristics of the welding process, the two form a seamless integral structure. During shotcreting operations, the hydraulic vibration damper 640 must withstand the periodic vibrations and instantaneous impacts transmitted by the shotcreting robot 500. It can evenly distribute the load onto the bushing 690 and the pin 620, preventing localized stress spikes caused by gaps due to loose connections. This effectively prevents fatigue fracture of components under long-term dynamic loads, ensuring the structural stability of the hydraulic vibration damper 640 under complex working conditions.

[0047] Reference Figure 2 According to the present invention, a hydraulic vibration damping adapter 600 is provided, which has multiple bolt holes 631. The connecting plate 630 and the spray anchor robot 500 are connected by fasteners passing through the bolt holes 631.

[0048] Understandably, the multiple bolt holes 631 on the connecting plate 630, along with fasteners (such as bolts and nuts), connect the connecting plate 630 to the shotcrete robot 500. Through the coordinated action of multiple connection points, the vibration and working force generated by the shotcrete robot 500 can be evenly distributed onto the connecting plate 630, avoiding loosening or breakage caused by concentrated force at a single point connection. This rigid connection method ensures the relative positional stability between the shotcrete robot 500 and the adapter, preventing shaking caused by connection failure during operation, and providing a structural basis for the effective transmission of vibration energy to the hydraulic vibration damper 640 through the connecting plate 630.

[0049] Reference Figure 2 According to the present invention, a hydraulic vibration damping adapter 600 is provided, wherein the distribution position of multiple bolt holes 631 on the connecting plate 630 is located inside the overall range formed by the corresponding connection positions of multiple hydraulic vibration dampers 640 and the connecting plate 630.

[0050] Understandably, the multiple bolt holes 631 are distributed within the overall area formed by the corresponding connection positions of the multiple hydraulic vibration dampers 640 and the connecting plate 630. This allows the force transmitted from the spraying and anchoring robot 500 to the connecting plate 630 via the bolts to act more concentratedly on the connection area of ​​the hydraulic vibration dampers 640. This distribution shortens the force transmission distance from the connection point to the hydraulic vibration damper 640, reduces the dispersion and loss of force during transmission, and allows the vibration energy generated by the spraying and anchoring robot 500 to be more directly captured and converted by the hydraulic vibration damper 640, thereby improving the absorption and attenuation efficiency of the vibration damping system.

[0051] Reference Figure 1The invention also provides a shotcrete boom truck 10, including a chassis 100, multiple hydraulic support arms 200, a telescopic arm 300, a hydraulic arm 400, and a shotcrete robot 500. The multiple hydraulic support arms 200 are sequentially hinged to each other, with the first end of each hydraulic support arm 200 hinged to the chassis 100; the telescopic arm 300 is hinged to the end of each hydraulic support arm 200; the hydraulic arm 400 is connected to the telescopic end of the telescopic arm 300; and the shotcrete robot 500 is connected to the hydraulic arm 400 via a hydraulic vibration damping adapter 600 as described above.

[0052] Understandably, the chassis 100, as the basic load-bearing component of the spray anchor boom truck 10, provides a stable support platform for the entire equipment. The chassis 100 can distribute the weight of the equipment itself and various loads generated during operation, ensuring the overall stability of the vehicle when parked and operating in different terrains (such as slopes, tunnels, and other construction scenarios), and is the foundation for the installation and operation of all other components.

[0053] Multiple hydraulic support arms 200 are hinged end-to-end, with the first end hinged to the chassis 100. This hinged structure allows for relative rotation between the support arms, and, in conjunction with hydraulic drive, the extension angle and support position of the support arms can be flexibly adjusted. During operation, the multiple hydraulic support arms 200 work together to expand the equipment's support range, enhance the vehicle's stability in complex terrain, and prevent the vehicle from tilting or overturning due to a shift in the center of gravity. Simultaneously, their adjustability provides a basis for adjusting the working position of the subsequent telescopic boom 300 and hydraulic boom 400.

[0054] The telescopic boom 300 is hinged at the end to the hydraulic support boom 200, and has its own telescopic function. The hinged structure allows it to rotate relative to the hydraulic support boom 200. Combined with the telescopic action, it can greatly expand the working radius, allowing the shotcrete robot 500 to reach different construction positions, meet diverse shotcrete operation needs, and improve the equipment's operating coverage.

[0055] The hydraulic arm 400 is connected to the telescopic end of the telescopic arm 300, serving as a component for transmitting power and controlling the posture of the shotcrete manipulator 500. It can achieve multi-directional swinging and rotation via hydraulic drive, precisely adjusting the working angle and position of the shotcrete manipulator 500, enabling the shotcrete concrete to be accurately sprayed onto the target area, thus laying the foundation for improved operational accuracy.

[0056] The shotcrete robot 500 is connected to the hydraulic arm 400 via the aforementioned hydraulic vibration damping adapter 600, which can effectively attenuate the harmful vibrations generated during the operation of the shotcrete robot 500.

[0057] Reference Figure 1According to the present invention, a spray anchor articulated boom truck 10 also includes a pipeline system 800 and a lifting ring structure 700. The lifting ring structure 700 is fixed on the telescopic boom 300. One end of the pipeline system 800 passes through the lifting ring structure 700 and is connected to the spray anchor robot 500. The other end of the pipeline system 800 is used to connect with external equipment.

[0058] Understandably, the pipeline system 800 serves as a connection channel between external equipment and the shotcrete robot 500. The concrete provided by the external equipment needs to be precisely delivered to the spraying device of the shotcrete robot 500 through the pipeline, and the hydraulic oil that drives the robot's movements also relies on the pipeline system 800 for circulation.

[0059] The lifting ring structure 700 is fixed to the telescopic boom 300 and constrains the piping system 800. During the operation of the spray anchor boom truck 10, the frequent movement of the telescopic boom 300 and the hydraulic boom 400 can easily cause irregular shaking of the piping system 800. The lifting ring structure 700 can limit the movement of the piping, controlling its trajectory within a safe range and preventing rigid collisions between the piping and other moving parts of the equipment, thereby reducing the risk of piping damage. In addition, when the equipment is operating at height or in confined spaces, the orderly piping layout can reduce the problem of limited boom movement caused by piping entanglement, ensuring that the telescopic boom 300 and the hydraulic boom 400 can flexibly adjust their working posture and improve the equipment's adaptability to complex construction environments.

[0060] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
