Description

Technical Field

[0001] The present disclosure relates to the technical field of handling auxiliary equipment, and more particularly, to a lifting device for an SVG module. Background Art

[0002] An SVG module (Static Var Generator) is a device that connects a self-commutated bridge circuit to the power grid through a reactor or directly in parallel, adjusts the phase and amplitude of the AC side output voltage of the bridge circuit, or directly controls the AC side current of the circuit, so that the circuit absorbs or emits reactive power that meets the requirements, achieving the purpose of dynamic reactive power compensation. In actual use, multiple SVG modules are generally placed on the same placement rack. The placement rack will be divided into multiple areas in the horizontal and height directions. Each SVG module is placed in one area, and multiple placement racks are arranged side by side or at intervals, and the distance between adjacent two placement racks is small. Since the weight of a single SVG module is relatively large, about 90 kilograms, it is difficult to manually carry an SVG module with a certain height out of the placement position in a narrow space. Not only does it take a long time to pick up and place, but it also easily leads to certain safety risks and reduces the replacement and maintenance efficiency of the SVG module. Summary of the Utility Model

[0003] The purpose of the present disclosure is to provide a lifting device for an SVG module to solve the problem of difficult handling of existing SVG modules during maintenance.

[0004] To achieve the above purpose, the present disclosure provides a lifting device for an SVG module, including:

[0005] A bottom plate;

[0006] A base, which is arranged above the bottom plate and is used for placing the SVG module;

[0007] A lifting part, which is arranged between the bottom plate and the base. The lifting part includes a power member and a telescopable lifting bracket. Both ends of the lifting bracket are respectively connected to the bottom plate and the base, and the power member is used to drive the lifting bracket to expand and contract; and

[0008] A conveying part, which is arranged above the base and extends along the length direction of the base. The conveying part includes a plurality of rotating rollers arranged side by side, and the rotating rollers are rotatably arranged on the base.

[0009] Optionally, there are two spaced-apart conveying parts.

[0010] Optionally, a lapping plate is further arranged above the base. The lapping plate is hinged to one side edge of the base and is located between the two conveying parts.

[0011] Optionally, the power component is a hydraulic rod, and the hydraulic rod includes:

[0012] A hydraulic pump;

[0013] A cylinder barrel, which is communicated with the hydraulic pump, and one end of the cylinder barrel is connected to the bottom plate;

[0014] A piston rod, which is telescopically arranged in the cylinder barrel, and one end of the piston rod away from the cylinder barrel is connected to the lifting bracket; and

[0015] A handle, which is connected to the hydraulic pump.

[0016] Optionally, an extension handle is sleeved on the outside of the handle.

[0017] Optionally, the lifting bracket is a quadrilateral wire frame, and the quadrilateral wire frame includes multiple cross-hinged support rods.

[0018] Optionally, the lifting part further includes a telescopable buffer rod, and two ends of the buffer rod are respectively connected to the bottom plate and the base.

[0019] Optionally, the buffer rod includes:

[0020] A connecting section, one end of the connecting section is connected to the base, and the other end extends towards the end away from the base;

[0021] A core rod, which is connected to the end of the connecting section away from the base;

[0022] A sleeve rod, which is movably sleeved on the outside of the core rod, and one end of the sleeve rod is connected to the bottom plate, and the other end extends towards the end away from the bottom plate; and

[0023] An elastic member, which is sleeved on the outside of the core rod, and one end of the elastic member is connected to the end of the sleeve rod away from the bottom plate, and the other end is connected to the end of the connecting section away from the base.

[0025] Optionally, the lifting device further includes a plurality of universal wheels, and the plurality of universal wheels are arranged at intervals under the bottom plate.

[0026] Through the above technical solution, when the SVG module is placed on the base, driving the lifting bracket to expand and contract by the power component can drive the base to move in the up and down direction, so that the height of the SVG module can be adjusted according to the target position where the SVG module is placed.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0032] The following will describe in detail the specific implementation of the present disclosure with reference to the drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.

[0033] In the present disclosure, unless otherwise stated, the orientation terms such as "upper" and "lower" are defined according to the arrangement direction of the lifting device during actual use, and the orientation terms such as "inner" and "outer" are defined according to the contour of the corresponding component. The terms "first", "second", etc. are used to distinguish different components, and do not have sequentiality or importance. In addition, in the following description, when referring to the drawings, unless otherwise explained, the same reference numerals in different drawings represent the same or similar elements.

[0034] According to an embodiment of the present disclosure, as Figure 1 shown, a lifting device for an SVG module is provided, including a bottom plate 1, a base 2, a lifting part, and a conveying part 4. The base 2 can be arranged above the bottom plate 1 and is used for placing the SVG module. The lifting part can be arranged between the bottom plate 1 and the base 2. The lifting part includes a power member 31 and a telescopically liftable bracket 32. Both ends of the liftable bracket 32 are respectively connected to the bottom plate 1 and the base 2. The power member 31 can be used to drive the liftable bracket 32 to expand and contract. The conveying part 4 can be arranged above the base 2 and extends along the length direction of the base 2. The conveying part 4 includes a plurality of rotating rollers 41 arranged side by side, and the rotating rollers 41 are rotatably arranged on the base 2.

[0035] Through the above technical solution, when the SVG module is placed on the base 2, driving the liftable bracket 32 to expand and contract by the power member 31 can drive the base 2 to move in the up and down direction, so that the height of the SVG module can be adjusted according to the target position where the SVG module is placed. After the base 2 is adjusted to the appropriate height, under the rotation of the plurality of rotating rollers 41, the operator can more easily push the SVG module on the base 2. The lifting device can not only adjust the SVG module to different heights according to the target position, but also more labor-savingly push the SVG module into the corresponding position. When the SVG module needs to be taken out from the target position, the base 2 can be first adjusted to the appropriate height, and with the assistance of the rotation of the plurality of rotating rollers 41, the SVG module can also be more labor-savingly moved from the target position to the base 2. This can effectively reduce the physical burden of the operator, and also reduce the possibility of safety accidents and equipment damage caused by the SVG module falling during manual handling, speed up the loading and unloading speed of the SVG module, be convenient and fast, time-saving and labor-saving, and improve work efficiency and accuracy.

[0036] It should be noted that when the SVG module needs to be transported to the target position after maintenance, the lifting device can be transported to the designated position first. Since the spacing of the placement racks for the SVG module generally forms a narrow aisle, the length of the narrow aisle is sufficient but the width is insufficient. Therefore, external equipment can easily assist in placing the SVG module into the lifting device located on the narrow aisle. However, the external equipment cannot enter this aisle, so it is impossible to place the SVG module into the placement racks on both sides of the narrow aisle in this aisle. Therefore, it is necessary for the external equipment to first place the SVG module into the lifting device, and then adjust the position through the lifting device and place the SVG module into the corresponding area of the placement rack. The length of the rotating roller 41 can be determined according to the length of the lifting device, and the present disclosure does not limit this. The rotational connection mode between the rotating roller 41 and the base 2 can be that a core shaft can be provided in the middle of the rotating roller 41 to connect with the base 2, and the rotating roller body rotates relative to the core shaft, and the core shaft is lower than the upper surface of the rotating roller 41 to prevent affecting the contact between the rotating roller body and the SVG module. It can also be that there is a fixed frame that fits the shape of the conveying part 4 on the outer side of the conveying part 4, and the fixed frame is lower than the upper surface of the conveying part 4. A plurality of rotating rollers 41 are arranged side by side in the fixed frame, and their horizontal positions can be limited on the premise of keeping the rotating rollers 41 rotating, and the present disclosure does not limit this. The lifting device can also include a plurality of universal wheels 6, and the plurality of universal wheels 6 can be arranged at intervals under the bottom plate 1 to drive the lifting device to move and further adjust the position of the lifting device, so as to adjust the position of the SVG module placed on the lifting device and make it more accurately placed in the target placement position.

[0037] Further, as Figure 1 shown, the conveying parts 4 can be two arranged at intervals, and the two conveying parts 4 can support the SVG module from both sides, making the movement of the SVG module more stable and not easily deviating from the moving position during the rolling process of the conveying parts 4.

[0038] Further, as Figure 1 shown, a lapping plate 5 is further provided above the base 2. The lapping plate 5 is hinged to one side edge of the base 2 and is located between the two conveying parts 4. The lapping plate 5 can be used to insert into the bracket at the target position where the SVG module is placed, so that the lifting device is aligned with the bracket at the target position and the placement position of the SVG module is more accurately positioned. Here, the hinged connection between the lapping plate 5 and the edge of the base 2 can make the lapping plate 5 extend out of the base 2 when in use, and when the lapping plate 5 is not needed, the lapping plate 5 can be rotated and placed above the base 2 to prevent the lapping plate 5 from protruding from the edge of the base 2 and interfering with other operations.

[0039] According to an embodiment of the present disclosure, as Figure 1As shown, the power member 31 can be a hydraulic rod, and the hydraulic rod can include a hydraulic pump, a cylinder barrel 311, a piston rod 312 and a handle. Among them, the cylinder barrel 311 is communicated with the hydraulic pump, one end of the cylinder barrel 311 is connected to the bottom plate 1, the piston rod 312 is telescopically arranged in the cylinder barrel 311, and the end of the piston rod 312 away from the cylinder barrel 311 is connected to the lifting bracket 32. Here, the cylinder barrel 311 can be divided into two non-communicating cylinder bodies by the piston rod 312, and the two cylinder bodies are respectively communicated with the hydraulic pump. By pumping liquid into different cylinder bodies through the hydraulic pump to drive the piston rod 312 to move, when the hydraulic pump pumps liquid into one cylinder body, the liquid of the same volume in the other cylinder body flows back to the hydraulic pump. The handle can be connected to the hydraulic pump for controlling the hydraulic pump to pump liquid into different cylinder bodies. Here, an extension handle 313 is sleeved outside the handle, and the length of the extension handle 313 is longer than that of the handle itself, which can make it more labor-saving for the operator to pull the handle.

[0040] According to an embodiment of the present disclosure, as Figure 1 shown, the lifting bracket 32 is a quadrilateral wire frame, and the quadrilateral wire frame includes a plurality of cross-hinged support rods 321. Taking 4 support rods 321 as an example, the 4 support rods 321 can be hinged in pairs to form two X-shaped frames. Two support rods 321 can rotate around the middle hinge point of the X-shaped frame. The two same-side endpoints of the two X-shaped frames can be correspondingly hinged to each other, that is, the two X-shaped frames can be spliced into a movable parallelogram. Multiple X-shaped frames can be correspondingly hinged to form a plurality of adjacent parallelograms. Since the four points of the parallelogram are all hinge points, the parallelogram is movable. By changing the shape of the parallelogram through movement, the telescoping of the lifting bracket 32 can be completed. Here, the power member 31 can be connected to any one of the support rods 321, and by pushing the support rod 321 to move, other support rods 321 can be indirectly driven to move, so as to complete the telescoping of the lifting bracket 32. In addition, a fixing member 11 with a slot can be arranged above the bottom plate 1. The lower end of the quadrilateral wire frame can be connected to the slot of the fixing member 11, and the quadrilateral wire frame can be received in the fixing member 11 after being folded. The present disclosure does not limit this.

[0041] In addition, as Figure 1 shown, the lifting part can further include a telescopic buffer rod 33. The two ends of the buffer rod 33 are respectively connected to the bottom plate 1 and the base 2 to form a stable support for the base 2 and reduce the shaking of the base 2 during the lifting process.

[0042] Specifically, as Figure 1As shown in the figure, the buffer rod 33 may include a connecting section 331, a core rod 332, a sleeve rod 333, and an elastic member 334. One end of the connecting section 331 may be connected to the base 2, and the other end extends away from the base 2. The core rod 332 may be connected to the end of the connecting section 331 away from the base 2. The sleeve rod 333 may be movably sleeved outside the core rod 332, and one end of the sleeve rod 333 is connected to the bottom plate 1, and the other end extends away from the bottom plate 1. The elastic member 334 may be sleeved outside the core rod 332, and one end of the elastic member 334 is connected to the end of the sleeve rod 333 away from the bottom plate 1, and the other end is connected to the end of the connecting section 331 away from the base 2. The elastic member 334 may be a spring or a rubber member. The spring can play a buffering role, enabling the base 2 to move more smoothly during the lifting process and reducing the shaking of the base 2 during the lifting process. Here, the sleeve rod 333 and the core rod 332 may also be the cylinder and piston rod structure in a hydraulic rod, and the present disclosure does not limit this.

[0043] Regarding the number and arrangement positions of the buffer rods 33, as Figure 1 shown, there may be three buffer rods 33 arranged at intervals. The bottom plate 1 and the base 2 may both be quadrilateral structures, and the corners of the bottom plate 1 and the corners of the base 2 are arranged in one-to-one correspondence. One end of each buffer rod 33 is respectively connected to a corner of the bottom plate 1 and the corresponding corner of the base 2. The power member 31 and the lifting bracket 32 are both connected to the middle parts of the bottom plate 1 and the base 2. That is, the three buffer rods 33 can be located at three corners of the bottom plate 1 and the base 2, leaving one corner without arranging a buffer rod 33. This arrangement method can have a larger operating space for the operator to drive the power member 31 or perform maintenance and adjustment on the power member 31 and the lifting bracket 32 on the basis of ensuring the stable support of the buffer rods 33 for the base 2, improving the user experience of the operator. It can prevent the situation where the operating space is too small due to buffer rods 33 being arranged at all four corners, making it inconvenient for the operator to operate.

[0045] In addition, it should be noted that, in the various specific technical features described in the above specific embodiments, they can be combined in any appropriate manner without conflict. To avoid unnecessary repetition, the present disclosure does not separately describe various possible combination methods.

[0046] Furthermore, any combination can be made between various different embodiments of the present disclosure as long as it does not violate the idea of the present disclosure, and it should also be regarded as the content disclosed by the present disclosure.
