[0002] At present, the STATCOM system includes 2 valve towers, which are respectively arranged in two independent valve halls. Each valve tower includes three phases of A, B, and C. The single-module size is: 1371*340*520mm, and the weight exceeds 0.2t. During the maintenance of a single module in the prior art, due to the limited space inside the valve hall, an insulated high and low stool is usually used to directly maintain the module. However, it is difficult to align a single module and pull it out during this process. Due to the interference of the columns on both sides, the problem of the two-side modules is more prominent.

[0003] After searching the prior art, it is found that a Chinese patent with the publication number CN110240058B discloses a valve tower module replacement device and a valve tower module replacement method, which includes a module transfer mechanism. The module transfer mechanism includes two units. One unit is a valve tower module support and transfer unit, and the other unit is a pull rope unit. The valve tower module support and transfer unit includes a bottom support frame and an outer frame. A receiving area suitable for accommodating the valve tower module is arranged between the outer frame and the bottom support frame. The pull rope unit includes at least four suspension ropes and a total rope connected to at least four suspension ropes at the same time.

[0041] In order to make the content of the present invention easier to be clearly understood, the present invention will be further described in detail below according to specific embodiments in conjunction with the accompanying drawings.

[0042] Embodiment 1

[0043] As Figures 1-5 shown, a valve tower module maintenance and loading / unloading device includes:

[0044] A base assembly 1 adapted to be driven to move up and down;

[0045] A moving assembly 2, the moving assembly 2 is slidably fitted on the base assembly 1 and is adapted to longitudinally move relative to the base assembly 1;

[0046] A maintenance guide rail group 10, the maintenance guide rail group 10 is installed on the moving assembly 2, the maintenance guide rails 3 in the maintenance guide rail group 10 correspond one by one to the rail spacing and quantity of the module to be maintained 4, and the maintenance guide rails 3 are adapted to receive the module to be maintained 4 after the moving assembly 2 and the base assembly 1 move in place; wherein, after the moving assembly 2 and the base assembly 1 move in place, the corresponding guide rails of the maintenance guide rails 3 and the module to be maintained 4 are in the same extension direction (i.e., on the same axis, and at this time, the two are aligned in the height direction and the longitudinal direction).

[0047] In this embodiment, as Figure 2 shown, the base assembly 1 may include a main beam and a frame or platform formed by welding, with reinforcing beams evenly distributed in the middle of the front and rear ends. A universal wheel adapter plate is welded on the bottom main beam of the base assembly 1, and universal wheels can be installed as needed. The universal wheels and the universal wheel adapter plate can be connected by bolts.

[0048] In this embodiment, as Figure 2 shown, the moving assembly 2 can be slidably fitted on the base assembly 1 through a plurality of guide rail slider pairs. The guide rail slider pairs can be of the following structure, including: a linear guide rail fixed on the reinforcing beam of the base assembly 1 by screws, a slider connected to the linear guide rail through a buckle, and the moving assembly 2 is connected to the slider by screws. The slider can move back and forth unidirectionally on the linear guide rail, and the side shift range can be 0 - 100 mm. Of course, the side shift range can be set according to specific needs and is not limited to 0 - 100 mm.

[0049] Specifically, as Figures 1-2 shown, in order to facilitate the movement of the module to be maintained 4 onto the maintenance guide rail group 10, the module to be maintained 4 can move horizontally on the maintenance guide rail group 10; specifically, a plurality of rollers are provided on both the maintenance guide rails 3 and the module to be maintained 4, and through these rollers, the module to be maintained 4 can move horizontally.

[0050] Specifically, as Figures 1-2 shown, at least one lateral movement limiting component 5 for limiting the movement of the module 4 to be overhauled is provided on the base assembly 1 after the module 4 to be overhauled moves into place on the overhaul guide rail group 10.

[0051] Specifically, as Figure 2 shown, the lateral movement limiting component 5 may have the following structure, including two lateral movement limiting assemblies. One of the two lateral movement limiting assemblies is detachably or movably mounted on the base assembly 1. After the module 4 to be overhauled moves into place, the two lateral movement limiting assemblies respectively abut against the two sides of the module 4 in the lateral direction to limit the movement of the module 4 on the overhaul guide rail group 10.

[0052] In this embodiment, as Figure 2 shown, the lateral movement limiting assembly away from the valve tower is in an inverted L shape, generally fixed to the base assembly 1 by welding and strengthened with reinforcing ribs; the lateral movement limiting assembly close to the valve tower is a Z-shaped body, also strengthened with reinforcing ribs, and the reinforcing ribs are welded to the Z-shaped body. It can be connected to the moving assembly 2 by bolts or by pins, and the installation is simple and convenient. The two lateral movement limiting assemblies can not only prevent the module 4 to be overhauled from moving horizontally, but also have a certain limiting effect in the vertical direction.

[0053] Specifically, as Figure 2 shown, the valve tower module overhaul loading and unloading device further includes a longitudinal movement limiting component 6 for limiting the longitudinal movement of the moving assembly 2 after the moving assembly 2 moves into place longitudinally.

[0054] Specifically, as Figure 2 shown, the longitudinal movement limiting component 6 may include the following structure, specifically: two longitudinal movement limiting assemblies, and the two longitudinal movement limiting assemblies respectively abut against the two sides of the moving assembly 2 in the longitudinal direction to limit the longitudinal movement of the moving assembly 2 on the base assembly 1.

[0055] Specifically, as Figures 2-3 shown, the longitudinal movement limiting assembly may have the following structure, including:

[0056] a connecting member 61, and the connecting member 61 is connected to the base assembly 1;

[0057] a screw rod 62, and the screw rod 62 is threadedly connected to the connecting member 61. By screwing the screw rod 62 against the corresponding side of the moving assembly 2, the movement of the module 4 to be overhauled on the overhaul guide rail group 10 is locked, and the position of the moving assembly 2 is adjusted.

[0058] In this embodiment, as Figures 2-3As shown, the connecting member 61 can be welded on the main beam of the base assembly 1, a through hole is opened on the connecting member 61, and a nut is welded on one side, and the distance against the moving assembly 2 can be adjusted by the nut on the screw 62 on the connecting member 61, so as to achieve high precision and easy use, and the overall height of the longitudinal moving limit assembly can be adjusted with the height of the moving assembly 2.

[0059] Specifically, Figure 2 As shown, the base assembly 1 is driven to move up and down by a lifting device with fork teeth, and the base assembly 1 is provided with four fork tooth connecting parts 7 connected to the fork teeth of the lifting device.

[0060] In this embodiment, if Figure 2 As shown, the lifting device with forks can use a manual stacker. The use of a manual stacker can improve the stability, accuracy and safety of transportation. It is cheap and easy to maintain, and can improve the disassembly efficiency of the module 4 to be repaired. The economy of using a manual stacker can save maintenance costs.

[0061] Specifically, Figures 2-3 As shown, the fork tine connecting component 7 may specifically have the following structure, including:

[0062] An adjusting screw 71, wherein the adjusting screw 71 is connected to the base assembly 1 through threads;

[0063] The limit head 72 is installed on the adjusting screw 71. A space for accommodating the fork tines is formed between the limit head 72 and the base assembly 1. By rotating the adjusting screw 71, the space for accommodating the fork tines is changed, so that the base assembly 1 and the fork tines are locked.

[0064] In this embodiment, if Figures 2-3 As shown, the limit head 72 is in the shape of a square tube, with a hole at the bottom, and the size of the limit head 72 can be adjusted according to the size of the fork teeth; the upper part of the adjusting screw 71 is a bare rod with a radial hole, and the bare rod part passes through the through hole at the bottom of the limit head 72, and a bolt is used to pass through the radial hole at the top of the adjusting screw 71 to connect the adjusting screw 71 with the limit head 72; the middle part of the adjusting screw 71 is threaded, and the lower part is also threaded. A transfer structure is welded in the through hole on the reinforcing beam of the base assembly 1. After the lifting device with fork teeth lifts the tooling, the adjusting screw 71 cooperates with the transfer structure through the thread, and the upper and lower distances of the adjusting screw 71 are adjusted in real time, so as to improve its versatility and be applicable to forks of various specifications; the middle part of the transfer structure is threaded to cooperate with the adjusting screw 71, and there are four fork tooth connecting parts 7, which are placed in the frame or platform formed by the base assembly 1. Of course, the number of fork tooth connecting parts 7 is not limited to four, and can be set as needed.

[0065] Specifically, Figure 2As shown, the valve tower module maintenance and handling device further includes an auxiliary positioning assembly 8 adapted to be disposed on the valve tower. After the moving assembly 2 and the base assembly 1 are moved into place, the moving assembly 2 is adapted to abut against the auxiliary positioning assembly 8 to assist in positioning.

[0066] Specifically, as Figure 2 and Figures 4-5 shown, the auxiliary positioning assembly 8 includes a connection reference portion and an auxiliary positioning portion;

[0067] The connection reference portion includes a longitudinal connection reference surface 801 that abuts against the side surface of the valve tower in the longitudinal direction, a transverse reference surface 802 that abuts against the side surface of the valve tower in the transverse direction, and a vertical reference surface 803 that abuts against the side surface of the valve tower in the up and down direction;

[0068] The auxiliary positioning portion includes a longitudinal positioning surface 804 and a vertical positioning surface 805; after the moving assembly 2 and the base assembly 1 are moved into place, the moving assembly 2 is adapted to abut against the longitudinal positioning surface 804 and the vertical positioning surface 805.

[0069] Specifically, as Figure 2 and Figures 4-5 shown, the auxiliary positioning assembly 8 includes a plate 810. The plate 810 extends upward to form at least one upper fin 811, and the plate 810 extends downward to form a first lower fin 813. The side surface of the upper fin 811 in the longitudinal direction forms a longitudinal connection reference surface 801, the side surface of the first lower fin 813 in the transverse direction forms a transverse reference surface 802, the side surface of the first lower fin 813 in the longitudinal direction forms a longitudinal positioning surface 804, a partial side surface of the plate 810 in the vertical direction forms a vertical positioning surface 805, and a partial side surface of the plate 810 in the vertical direction forms a vertical reference surface 803.

[0070] Specifically, as Figure 4 shown, the plate 810 extends downward to form a second lower fin 812. The side surface of the second lower fin 812 in the transverse direction forms another transverse reference surface 802, and the two transverse reference surfaces 802 are disposed opposite to each other.

[0071] In this embodiment, as Figure 2 and Figures 4-5 shown, the auxiliary positioning assembly 8 is fixed to one side of the module 4 to be maintained. The first lower fin 813 and the second lower fin 812 are directly clamped on the cross beam between the two valve towers. The second lower fin 812 forms an angular structure for quickly aligning the maintenance guide rail 3 on the moving assembly 2 with the corresponding guide rail of the module 4 to be maintained; the left and right limits are performed through the symmetric upper fins 811 on the left and right sides to prevent the auxiliary positioning assembly 8 from moving left and right.

[0072] Specifically, as Figures 4-5 shown, the longitudinal connection reference surface 801 abuts against the side surface of the module on the valve tower in the longitudinal direction;

[0073] The horizontal reference plane 802 abuts against the lateral side of the upper cross beam of the valve tower in the horizontal direction;

[0074] The vertical reference plane 803 abuts against the vertical side of the upper cross beam of the valve tower.

[0075] Embodiment 2

[0076] As Figures 1-5 shown, a loading and unloading method of a valve tower module maintenance loading and unloading device, the steps of the method include:

[0077] Vertically lift the base assembly 1 and horizontally move the moving assembly 2 so that the base assembly 1 and the moving assembly 2 move into place, so that the maintenance guide rail 3 and the corresponding guide rail of the module 4 to be maintained are in the same extension direction;

[0078] Horizontally move the module 4 to be maintained, and horizontally move the module 4 to be maintained onto the maintenance guide rail group 10 and into place;

[0079] Use the valve tower module maintenance loading and unloading device to transfer the module 4 to be maintained to a designated position for maintenance.

[0080] In this embodiment, the steps of the method can specifically be:

[0081] S1: Disconnect the power supply of the valve tower, turn off the water cooling system, safely ground the incoming line side of the module 4 to be maintained in the valve tower, and drain the water on the valve tower side;

[0082] S2: The maintenance personnel use an insulated high and low stool to remove the connections such as the limit of the module 4 to be maintained;

[0083] S3: First, adjust the fork teeth of the lifting device with fork teeth so that the length direction of the fork teeth is consistent with the horizontal direction of the valve tower module maintenance loading and unloading device, and then adjust the adjusting screw 71 of the fork tooth connecting component 7 until the adjusting screw 71 abuts against the fork teeth. At this time, the valve tower module maintenance loading and unloading device is in a state of being locked on the fork teeth;

[0084] S4: Use the lifting device with fork teeth to lift the valve tower module maintenance loading and unloading device to the height position of the module 4 to be maintained;

[0085] S5: Remove the connecting copper bars, water pipes and other devices between the horizontal movement limiting component close to the valve tower and the module 4 to be maintained;

[0086] S6: The maintenance personnel borrow an insulated high and low stool and stand on both sides of the valve tower module maintenance loading and unloading device. Pull the module 4 to be maintained into the maintenance guide rail group 10 through a T-shaped hook. When the module 4 to be maintained contacts the horizontal movement limiting component far from the valve tower, stop pulling the module 4 to be maintained, install the horizontal movement limiting component close to the valve tower, fix the module 4 to be maintained with the valve tower module maintenance loading and unloading device, and then lower the module 4 to be maintained to prevent the module 4 to be maintained from slipping;

[0087] S7: Move the entire lifting device of the fork teeth backward by about 100 mm.

[0088] S8: Lower the valve tower module maintenance and handling device to the ground.

[0089] S9: Use the valve tower module maintenance and handling device to transfer the module 4 to be maintained to a designated position for maintenance.

[0090] Among them, step S3 can specifically include:

[0091] S3-1: Adjust the fork teeth to make them reach the maximum outer width state.

[0092] S3-2: Connect the fork teeth to the fork tooth connection component 7. The length direction of the fork ruler is parallel to the depth direction of the valve tower module maintenance and handling device, and lock the tooling and the fork teeth by adjusting the adjusting screw 71 to ensure that there is no relative displacement between them, reducing the probability of interference and collision between the bottom plate of the module 4 to be maintained and the maintenance guide rail 3 during the subsequent movement of the module 4 to be maintained, and reducing the operation intensity of maintenance personnel.

[0093] Among them, step S4 can specifically include:

[0094] S4-1: First, fix the auxiliary positioning component 8 on one side of the module 4 to be maintained.

[0095] S4-2: Use the lifting device of the fork teeth to lift the valve tower module maintenance and handling device upward. Stop lifting when the upper surface of the moving component 2 contacts the vertical positioning surface 805 of the auxiliary positioning component 8. At this time, the maintenance guide rail group 10 on the moving component 2 has reached the same horizontal height as the guide rail of the module 10 to be maintained.

[0096] S4-3: Utilize the characteristic of the one-way reciprocating movement of the guide rail and slider of the moving component 2 to horizontally adjust the maintenance guide rail group 10. Stop moving when the side of the moving component 2 contacts the longitudinal positioning surface 804 of the auxiliary positioning component 8. At this time, the maintenance guide rail group 10 on the moving component 2 has reached the same axis as the guide rail of the module 10 to be maintained.

[0097] S4-4: Adjust the screw 62 on the longitudinal movement limiting component 6 to fix the moving component 2 on the base component 1.

[0098] S4-5: Remove the auxiliary positioning component 8.

[0099] Among them, step S5 can specifically include:

[0100] S5-1: Maintenance personnel stand on both sides of the valve tower module maintenance and handling device and use a T-shaped hook to pull the module 4 to be maintained outwards simultaneously.

[0101] S5-2: When one end of the module 4 to be overhauled away from the valve tower touches the L-shaped lateral movement limit component, stop pulling, place the Z-shaped lateral movement limit component on the reinforcing beam at the tail of the moving component 2, and fix it by means of a pin shaft.

[0102] In this embodiment, as Figures 1-2 shown, first guide the fork teeth of the lifting device with fork teeth into the fork tooth connection component, and lock the base component 1 on the fork teeth by adjusting the adjusting screw 71, reducing the probability of interference and collision between the bottom plate of the module 4 to be overhauled and the overhaul guide rail 3 during the subsequent movement of the module 4 to be overhauled, reducing the operation intensity of the overhaul personnel. At the same time, the base component 1 is fixed to the fork teeth, and the process is simple and convenient; when lifting, place the auxiliary positioning component 8 between the cross beams of the valve tower module interval. With the help of the auxiliary positioning component 8, quickly raise it to the same horizontal height as the module 4 to be overhauled, and at the same time, flexibly adjust the moving component 2 to align the overhaul guide rail 3 with the guide rail of the module 4 to be overhauled longitudinally, reducing the installation and docking time between the overhaul guide rail 3 and the module 4 to be overhauled, and reducing the requirements for the initial position of the lifting device with fork teeth, greatly improving the overhaul efficiency; finally, pull the module 4 to be overhauled into the overhaul guide rail group 10 through the T-shaped hook. When the module 4 to be overhauled touches the lateral movement limit component away from the valve tower, stop pulling the module 4 to be overhauled, install the lateral movement limit component close to the valve tower to limit the movement of the module 4 to be overhauled, and finally unload the valve tower module overhaul loading and unloading device to the ground and transfer it to the designated position for overhaul. In summary, the valve tower module overhaul loading and unloading device and the loading and unloading method have the characteristics of high safety, high efficiency, low cost, and high economy.
