[0018] Explanation of reference numerals in the attached figures Detailed Implementation

[0019] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0020] The cylinder auxiliary installation device of the present invention will now be described with reference to the accompanying drawings.

[0021] like Figures 1 to 5 As shown, the present invention provides a hydraulic cylinder auxiliary installation device, which includes a mobile trolley 10, an alignment adjustment mechanism 20, and an oil supply drive mechanism 30. The alignment adjustment mechanism 20 includes an alignment support frame 21 and a lifting drive component 22. The lifting drive component 22 is mounted on the mobile trolley 10 and is drivenly connected to the alignment support frame 21. The alignment support frame 21 is used to place and support the cylinder body portion 201 of the hydraulic cylinder 200 to be installed. The oil supply drive mechanism 30 is mounted on the mobile trolley 10 and is used to communicate with the cylinder body portion 201 and supply oil to the cylinder body portion 201 to drive the piston portion 202 of the hydraulic cylinder 200 to be installed to extend and retract.

[0022] It should be noted that the hydraulic cylinder auxiliary installation equipment of the present invention can be applied to the assembly operation of hydraulic cylinders to assist the operator in assembling the hydraulic cylinder 200 to be installed onto the structural component 300 to be assembled. The present invention does not limit the hydraulic cylinder 200 to be installed and the structural component 300 to be assembled. The hydraulic cylinder 200 to be installed can be a boom cylinder 200c, a stick cylinder 200a, a bucket cylinder 200b, etc., and the structural component 300 to be assembled can include a boom 301, a stick 302, a bucket 303, etc. The embodiment of the present invention is only described by taking the application of the hydraulic cylinder auxiliary installation equipment in the hydraulic cylinder assembly operation of a super-large front shovel excavator as an example.

[0023] Specifically, one end of the lifting drive component 22 is connected to the moving trolley 10, and the other end of the lifting drive component 22 is connected to the alignment support frame 21. The cylinder body 201 of the cylinder to be installed can be placed on the alignment support frame 21 so that the alignment support frame 21 supports the cylinder body 201. The lifting drive component 22 drives the alignment support frame 21 to rise and fall, so that the alignment support frame 21 drives the cylinder to be installed to rise and fall. The oil supply drive mechanism 30 can supply oil to the cylinder body 201 through communication with the cylinder body 201, thereby driving the piston part 202 of the cylinder to be installed to extend and retract. When assembling the cylinder to be installed, the cylinder to be installed is supported on the alignment support frame 21, and the moving trolley 10 drives the cylinder to be installed to rise and fall. The alignment support frame 21 and the cylinder 200 to be installed move to transfer the cylinder 200 to the bottom of the boom 301 and stick 302. The lifting drive 22 drives the alignment support frame 21 to lift and lower to adjust the height position of the cylinder 200. The oil supply drive mechanism 30 drives the piston part 202 to extend and retract to adjust the extension length of the piston part 202. There is no need to use a crane to lift the cylinder 200 to be installed, which reduces the obstruction of the cylinder 200 to be installed, improves the visibility of the assembly operation, and the height position of the cylinder 200 to be installed and the extension length of the piston part 202 are flexible and convenient to adjust, which reduces the assembly difficulty and makes it easier to assemble the cylinder 200 to be installed in a narrow installation space, thus improving the safety of the operation.

[0024] In this embodiment of the invention, the hydraulic cylinder auxiliary installation device further includes a control device, which includes a controller 40 communicatively connected to the lifting drive component 22. The controller 40 is configured to: According to the first alignment command, the lifting drive 22 drives the alignment support frame 21 to rise and fall, so that the alignment support frame 21 drives the oil cylinder 200 to be installed to switch to the first installation posture. When it is determined that the hydraulic cylinder 200 to be installed is in the first installation posture, a first alignment prompt signal is generated. The cylinder body 201 has a first mounting hole 2011 at the end away from the piston 202. The first mounting hole 2011 is configured to communicate with the first connection hole on the structural component 300 to be assembled when the hydraulic cylinder 200 to be installed is in the first installation posture.

[0025] like Figure 2 and Figure 9As shown, the controller 40 is communicatively connected to the lifting drive component 22 to control the lifting drive component 22 to drive the alignment support frame 21 to rise and fall. When assembling the hydraulic cylinder 200 to be installed, the controller 40 can control the lifting drive component 22 to start according to the first alignment command, so that the lifting drive component 22 drives the alignment support frame 21 and the hydraulic cylinder 200 supported on the alignment support frame 21 to rise and fall. When the hydraulic cylinder 200 to be installed rises and falls to the first installation posture, the controller 40 controls the lifting drive component 22 to stop. The controller 40 stops the hydraulic cylinder 200 to be installed in the first installation posture and generates a first alignment prompt signal accordingly. When the hydraulic cylinder 200 is in the first installation posture, the first mounting hole 2011 on the cylinder body 201 is aligned with the first connecting hole on the structural component 300 to be assembled. The operator can determine the alignment of the first mounting hole 2011 and the first connecting hole according to the first alignment prompt signal, which facilitates the operator to pass the first pin through the first mounting hole 2011 and the first connecting hole to connect the cylinder body 201 to the structural component 300 to be assembled. The controller 40 controls the lifting drive 22 to switch the hydraulic cylinder 200 to be installed to the first installation posture according to the first alignment command. The controller 40 also generates a first alignment prompt signal to prompt the operator that the hydraulic cylinder 200 is in the first installation posture. This not only makes the adjustment flexible and convenient, but also facilitates the adjustment of the position of the hydraulic cylinder 200 in a confined space. It also reduces the difficulty of alignment operation and makes it easier for the operator to determine the assembly position of the hydraulic cylinder 200, further improving the ease of assembly.

[0026] In this embodiment of the invention, the controller 40 is also communicatively connected to the oil supply drive mechanism 30, and the controller 40 is further configured to: According to the second alignment command, the oil supply drive mechanism 30 is controlled to supply oil to the cylinder part 201 to drive the piston part 202 to extend and retract, and the lifting drive component 22 is controlled to drive the alignment support frame 21 to rise and fall, so that the alignment support frame 21 drives the oil cylinder 200 to be installed to switch to the second installation posture. When it is determined that the hydraulic cylinder 200 to be installed is in the second installation posture, a second alignment prompt signal is generated. The piston part 202 has a second mounting hole 2021 at the end away from the cylinder body part 201. The second mounting hole 2021 is configured to communicate with the second connection hole on the structural component 300 to be assembled when the hydraulic cylinder 200 to be installed is in the second installation posture.

[0027] like Figure 2 and Figure 9As shown, the controller 40 is communicatively connected to the oil supply drive mechanism 30 to control the oil supply drive mechanism 30 to supply oil to the cylinder body 201, thereby driving the piston part 202 to extend and retract. When assembling the cylinder 200 to be installed, the controller 40 can, upon receiving a second alignment command, control the lifting drive component 22 to start and control the oil supply drive mechanism 30 to supply oil according to the second alignment command. This allows the lifting drive component 22 to drive the cylinder 200 to be installed to rise and fall, and to drive the piston part 202 to extend and retract, thereby causing the cylinder 200 to be installed to switch from the first installation posture. When the cylinder 200 to be installed is in the second installation position, the controller 40 generates a second alignment prompt signal. When the cylinder 200 to be installed is in the second installation position, the second mounting hole 2021 on the piston part 202 is aligned with the second connecting hole on the structural component 300 to be assembled. The operator can determine that the second mounting hole 2021 is aligned with the second connecting hole according to the second alignment prompt signal, which makes it easier for the operator to pass the second pin through the second mounting hole 2021 and the second connecting hole to connect the piston part 202 to the structural component 300 to be assembled. The controller 40 controls the lifting drive 22 and the oil supply drive mechanism 30 according to the second alignment command to switch the cylinder 200 to be installed to the second installation posture. The controller 40 generates a second alignment prompt signal to prompt the operator that the cylinder 200 to be installed is in the second installation posture. This not only makes the adjustment flexible and convenient, but also makes it easy to adjust the position of the cylinder 200 to be installed in a narrow space. It also reduces the difficulty of alignment operation, makes it easier for the operator to determine the assembly position of the cylinder 200 to be installed, and further improves the ease of assembly.

[0028] Furthermore, the controller 40 is also configured to control the oil supply drive mechanism 30 to supply oil to the cylinder body 201 to drive the piston 202 to extend and retract according to the second alignment command, and to control the lifting drive member 22 to drive the alignment support frame 21 to rise and fall, so that before the alignment support frame 21 drives the cylinder 200 to be installed to switch to the second installation posture, the following is also included: When it is determined that the hydraulic cylinder 200 to be installed is in the first assembly state, a second alignment command is obtained, wherein the first mounting hole 2011 and the first connecting hole are connected by a first pin when the hydraulic cylinder 200 to be installed is in the first assembly state.

[0029] Specifically, before executing the second alignment command, the controller 40 determines whether the cylinder 200 to be installed is in the first assembly state. When the cylinder 200 to be installed is in the first assembly state, the first pin passes through the first mounting hole 2011 and the first connecting hole, that is, the cylinder body 201 is connected to the structural component 300 to be assembled through the first pin. When the controller 40 determines that the cylinder 200 to be installed is in the first assembly state, it can determine that the cylinder body 201 and the structural component 300 to be assembled have been assembled. Then, it can obtain the second alignment command and adjust the cylinder 200 to be installed to the second installation posture according to the second alignment command. This effectively prevents the cylinder 200 to be installed from moving and extending before the cylinder body 201 is fully installed due to human error, and further improves the safety of operation.

[0030] Furthermore, the controller 40 is also configured to control the oil supply drive mechanism 30 to supply oil to the cylinder body 201 to drive the piston 202 to extend and retract according to the second alignment command, and to control the lifting drive 22 to drive the alignment support frame 21 to rise and fall, so that after the alignment support frame 21 drives the cylinder 200 to be installed to switch to the second installation posture, it also includes: When it is determined that the cylinder 200 to be installed is in the second assembly state, a reset command is obtained, wherein the second mounting hole 2021 and the second connecting hole are connected by the second pin when the cylinder 200 to be installed is in the second assembly state. According to the reset command, the lifting drive 22 drives the alignment support frame 21 to descend to the initial position.

[0031] Specifically, before executing the reset command, the controller 40 determines whether the cylinder 200 to be installed is in the second assembly state. When the cylinder 200 to be installed is in the second assembly state, the second pin passes through the second mounting hole 2021 and the second connecting hole, that is, the piston part 202 is connected to the structural component 300 to be assembled through the second pin. When the controller 40 determines that the cylinder 200 to be installed is in the second assembly state, it can determine that the piston part 202 and the structural component 300 to be assembled have been assembled. Then, it can obtain the reset command and adjust the alignment support frame 21 to retract relative to the vehicle body 12 according to the reset command, so as to avoid the cylinder 200 to be installed and the structural component 300 to be assembled, and prevent the vehicle body 12 from driving the alignment support frame 21 to collide with obstacles during the movement, thereby further improving the safety of operation.

[0032] In this embodiment of the invention, the control device further includes an operation panel 50. The mobile trolley 10 has a placement slot 11. The operation panel 50 is detachably disposed in the placement slot 11. The operation panel 50 is communicatively connected to the controller 40 and is used to manually set the first alignment command and the second alignment command.

[0033] like Figure 3 and Figure 9 As shown, when assembling the hydraulic cylinder 200 to be installed, the operator can take out the operation panel 50 from the placement slot 11. The operator can manually input the first alignment command and the second alignment command by interacting with the operation panel 50. The controller 40 is connected to the operation panel 50 to obtain the manually input first alignment command and the second alignment command. Then, the posture of the hydraulic cylinder 200 to be installed can be adjusted according to the first alignment command and the second alignment command, so as to facilitate the assembly of the hydraulic cylinder 200 to be installed onto the structural component 300 to be assembled, which greatly reduces the assembly difficulty and further improves the assembly convenience.

[0034] In this embodiment of the invention, the mobile vehicle 10 includes a body 12, wheels 13, and a driving mechanism 14. A lifting drive component 22 is disposed on the upper side of the body 12, and the wheels 13 are rotatably disposed on the lower side of the body 12. The driving mechanism 14 is drivenly connected to the wheels 13 and communicatively connected to the controller 40. The controller 40 is further configured to: generate a distance warning signal when it is determined that the collision detection distance is less than a first preset distance, and control the driving mechanism 14 to stop operating when it is determined that the collision detection distance is less than a second preset distance. The collision detection distance is set as the distance between the body 12 and the obstacle, and the first preset distance is greater than the second preset distance.

[0035] like Figures 2 to 5 and Figure 9 As shown, the driving mechanism 14 drives the wheels 13 to rotate, thereby moving the vehicle body 12. This allows the vehicle body 12 to transfer the cylinder 200 to be installed to the bottom of the boom 301 and stick 302 via the lifting drive component 22 and the alignment support frame 21. This facilitates convenient transfer and provides stable support. Furthermore, the controller 40 can acquire the collision detection distance in real time. The collision detection distance is used to characterize the real-time distance between the vehicle body 12 and obstacles, such as the boom 301, stick 302, and bucket 303. When the collision detection distance is less than a first preset distance, the controller 40 can determine that the vehicle body 12 has moved to a position close to the obstacle. By generating a distance warning signal, the controller 40 prompts the operator to slow down the travel speed of the trolley 10 to prevent collisions that could damage the cylinder 200 and the structural component 300 to be assembled, thus improving operational safety. Additionally, when the collision detection distance is less than a second preset distance, the controller 40 locks the driving mechanism 14 to prevent the trolley 10 from moving, thus preventing collisions caused by human error and further improving operational safety and reliability.

[0036] In this embodiment of the invention, the control device further includes an image acquisition unit 60, an audible and visual warning unit 70, and a distance sensor 80. The image acquisition unit 60, the audible and visual warning unit 70, and the distance sensor 80 are all mounted on the vehicle body 12 and are respectively connected to the controller 40. The image acquisition unit 60 is used to acquire image information of the hydraulic cylinder 200 to be installed and send it to the controller 40. The controller 40 can determine whether the hydraulic cylinder 200 to be installed is in a first installation posture, a second installation posture, a first assembly state, or a second assembly state based on the image information of the hydraulic cylinder 200 to be installed. The controller 40 can also send the generated first alignment prompt signal, second alignment prompt signal, or distance prompt signal to the audible and visual warning unit 70, so that the audible and visual warning unit 70 issues the first alignment prompt signal, second alignment prompt signal, or distance prompt signal to remind the operator. The distance sensor 80 is used to detect the collision detection distance and send the detection result to the controller 40, so that the controller 40 compares the received collision detection distance with the first preset distance and the second preset distance, and generates a distance prompt signal and locks the driving drive mechanism 14 accordingly, which simplifies the assembly difficulty and improves the assembly reliability. In addition, the control panel 50 can also be used for operators to manually set reset commands and driving commands. The controller 40 can control the lifting drive component 22 to drive the alignment support frame 21 to descend according to the reset command, and control the driving drive mechanism 14 to drive the wheels 13 to rotate according to the driving command, which improves the ease of operation.

[0037] In this embodiment of the invention, the alignment support frame 21 includes a support rod 211, a clamping assembly, and a clamping drive 212. The support rod 211 is driven to connect with the lifting drive 22. The clamping assembly includes a first clamping arm 213 and a second clamping arm 214 respectively rotatably disposed on the support rod 211. The first clamping arm 213 and the second clamping arm 214 are used for placing the cylinder part 201. The clamping drive 212 is used to drive the first clamping arm 213 and the second clamping arm 214 to swing towards each other and clamp the cylinder part 201, and to drive the first clamping arm 213 and the second clamping arm 214 to swing away from each other and release the cylinder part 201.

[0038] like Figure 6 and Figure 9As shown, the lower end of the support rod 211 is driven to connect with the lifting drive component 22, and the upper end of the support rod 211 is provided with a first clamping arm 213 and a second clamping arm 214 arranged opposite to each other. When assembling the hydraulic cylinder 200 to be installed, the cylinder body 201 is placed between the first clamping arm 213 and the second clamping arm 214. The clamping drive component 212 drives the first clamping arm 213 and the second clamping arm 214 to swing towards each other to clamp the cylinder body 201, which improves the assembly stability and reliability. In addition, the clamping drive component 212 is communicatively connected to the controller 40. When the controller 40 determines that the hydraulic cylinder 200 to be installed is in the second assembly state, it controls the clamping drive component 212 to drive the first clamping arm 213 and the second clamping arm 214 to swing away from each other to release the cylinder body 201. This effectively prevents the cylinder body 201 from being released before the assembly is completed due to human error, thus improving the safety of the operation.

[0039] Furthermore, such as Figure 6 As shown, the first clamping arm 213 and the second clamping arm 214 extend in a direction away from the support rod 211 and are arranged in an arc shape. The ends of the first clamping arm 213 and the second clamping arm 214 away from the support rod 211 are bent upwards so that the first clamping arm 213 and the second clamping arm 214 can be used to clamp cylinder parts 201 of various sizes, with strong adaptability and high versatility.

[0040] In embodiments of the present invention, such as Figure 6 As shown, the alignment support frame 21 also includes a limiting clamp 215. One end of the limiting clamp 215 is connected to the first clamping arm 213, and the other end of the limiting clamp 215 is detachably connected to the second clamping arm 214. When assembling the hydraulic cylinder 200 to be installed, the cylinder body 201 is placed between the first clamping arm 213 and the second clamping arm 214. The first clamping arm 213 and the second clamping arm 214 cooperate to clamp the cylinder body 201. By connecting the end of the limiting clamp 215 away from the first clamping arm 213 to the second clamping arm 214, the limiting clamp 215 limits the cylinder body 201 between the first clamping arm 213 and the second clamping arm 214, thereby improving the support stability. Furthermore, the limiting clamp 215 can be made of a flexible material to adaptably fit the cylinder body 201, further improving the limiting stability.

[0041] In this embodiment of the invention, the alignment adjustment mechanism 20 further includes a rotary drive component, which is driven to the mounting end of the lifting drive component 22 to drive the lifting drive component 22 to rotate. The lifting drive component 22 drives the alignment support frame 21 to rotate to adjust the angle of the hydraulic cylinder 200 to be installed, further improving the adjustment flexibility. It is understood that the lifting drive component 22, the rotary drive component, and the clamping drive component 212 can all be cylinders, electric cylinders, or hydraulic cylinders in the prior art. The types and driving methods of the lifting drive component 22, the rotary drive component, and the clamping drive component 212 are well known to those skilled in the art and are not part of the core improvement of this application, so they will not be described in detail here.

[0042] In this embodiment of the invention, the oil supply drive mechanism 30 includes an oil reservoir 31, an oil pump 32, and an oil supply line 33. The oil reservoir 31 is connected to the oil supply line 33 via the oil pump 32. A quick-connect coupling 34 is provided at the end of the oil supply line 33 furthest from the oil pump 32, and the quick-connect coupling 34 is used to connect to the cylinder block 201. Figure 5 , Figures 7 to 9 As shown, the quick-connect coupling 34 includes a male connector 341 and a female connector 342. The male connector 341 is located at the end of the oil supply line 33 away from the oil pump component 32. The female connector 342 is used to connect the male connector 341 and the cylinder block 201. The controller 40 is communicatively connected to the oil pump component 32, so that the controller 40 can control the oil pump component 32 to start, so that the oil in the oil tank 31 is pumped into the cylinder block 201 through the oil supply line 33 and the quick-connect coupling 34, thereby driving the piston 202 to extend and retract, so that the second mounting hole 2021 on the piston 202 can extend and retract to the position of the corresponding second connection hole, thereby facilitating the operator to assemble the piston 202 onto the structural component 300 to be assembled using the second pin, making the assembly convenient and quick.

[0043] Furthermore, such as Figure 5 As shown, the oil tank 31, the oil pump 32, and the driving mechanism 14 are all located inside the vehicle body 12. The oil supply line 33 passes through the vehicle body 12 to facilitate the connection of the quick-connect connector 34 to the cylinder block 201. In addition, a battery 15 is also provided inside the vehicle body 12. The battery 15 is electrically connected to the oil pump 32 and the driving mechanism 14 to supply power to the oil pump 32 and the driving mechanism 14, eliminating the need for an external power source and improving ease of use.

[0044] In this embodiment of the invention, the number of alignment support frames 21 is at least two, and the at least two alignment support frames 21 are spaced apart along the length direction of the moving trolley 10. The number of lifting drive components 22 is the same as the number of alignment support frames 21, and they are driven and connected one-to-one. Figures 2 to 4 As shown, the upper side of the vehicle body 12 is provided with two alignment support frames 21. Both alignment support frames 21 are used to place the cylinder body 201 to support the hydraulic cylinder 200 to be installed. Each alignment support frame 21 is driven to a lifting drive component 22. Each lifting drive component 22 is communicatively connected to the controller 40, so that the controller 40 can adjust the lifting height of the two alignment support frames 21 respectively, thereby adjusting the angle of the hydraulic cylinder 200 to be installed, improving the adjustment flexibility and facilitating the assembly of the hydraulic cylinder 200 to be installed in a narrow space.

[0045] Understandably, the number of alignment support frames 21 can also be set to three, four or other numbers. The number of lifting drive components 22 is consistent with the number of alignment support frames 21 and they are driven and connected one by one. The number of alignment support frames 21 can be flexibly set according to actual usage requirements. The hydraulic cylinder auxiliary installation device of the present invention does not limit the number of alignment support frames 21.
