Description

Technical Field

[0001] The present invention relates to the technical field of transformer bases, and particularly relates to a transformer installation base and a transportation device with adaptive shock absorption and buffering functions. Background Art

[0002] A transformer is a device that uses the principle of electromagnetic induction to change the AC voltage. Its main components are the primary coil, secondary coil, and iron core. Its main functions include voltage conversion, current conversion, impedance conversion, isolation, voltage stabilization, etc. Currently, large transformers are large in size and very heavy, so for the testing, commissioning, handling, and installation of transformers, lifting equipment is often used for movement. And in order to reduce the vibration during the operation of the transformer, a base with a buffering function needs to be installed under the transformer.

[0003] The current transformer installation base uses a buffering mechanism for buffering. However, during the hoisting process of the transformer, due to the unequal weights at both ends of the transformer or the non-central position of the hanging hook, it may cause the transformer to tilt. The tilted transformer is not convenient for positioning and installation. And when the tilted transformer is hoisted, one end of the transformer installation base will contact the installation point first, which may cause excessive local pressure on the internal buffering mechanism, resulting in mechanical damage to the internal buffering mechanism or damage to the installation base. Also, due to the too fast descending speed of the rope during hoisting, the base directly contacts the installation point, and then the transformer impacts the internal buffering mechanism under the action of inertia, causing damage. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a transformer installation base and a transportation device with adaptive shock absorption and buffering functions that can overcome or at least partially solve the above problems.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] An adaptive shock absorption and buffering transformer installation base, comprising: a base body, further comprising: a buffering component, arranged inside the base body; a controller, arranged inside the base body; an electronic inclinometer, arranged inside the base body; fixing plates, symmetrically and fixedly connected to both sides of the base body; sliding rods, symmetrically and slidably arranged on the fixing plates; a detection plate, arranged on the lower side of the fixing plates, and the detection plate is fixedly connected to the lower ends of the two sliding rods; springs, symmetrically and fixedly arranged between the detection plate and the fixing plates, and the springs are sleeved on the sliding rods; installation guide rails, symmetrically and fixedly connected to the lower side of the base body; second installation holes, opened on the installation guide rails; a locking mechanism for locking the sliding rods, arranged on the fixing plates; first installation holes, symmetrically opened on the detection plate.

[0007] Preferably, the buffer assembly includes at least two sets of first buffer mechanisms symmetrically arranged inside the base body. A buffer plate is slidably arranged on the upper side of the base body, and the buffer plate is fixedly connected to the upper ends of the first buffer mechanisms.

[0008] To facilitate locking the sliding rod, further, the locking mechanism includes an electric telescopic rod arranged on the detection plate, and a second friction semi-ring is fixedly connected to the output end of the electric telescopic rod.

[0009] To facilitate significant buffering of the transformer body, further, a plurality of second buffer mechanisms are fixedly connected inside the base body, and a first gap is provided between the upper ends of the second buffer mechanisms and the buffer plate.

[0010] To prevent the sliding rod from deforming and provide a certain amount of friction at the same time, a first friction semi-ring corresponding to the sliding rod is fixedly connected to the detection plate.

[0011] To facilitate disassembly of the electric telescopic rod, further, a connecting plate is fixedly connected to the detection plate, a connecting sleeve is detachably connected to the connecting plate, and the electric telescopic rods are symmetrically arranged on both sides of the connecting sleeve.

[0012] To facilitate protection of the transformer body, a protection frame is arranged between two adjacent sliding rods, and one side of the protection frame is L-shaped to protect the transformer body.

[0013] To facilitate providing different frames for transformer bodies with different shapes, further, first flange plates are symmetrically and fixedly connected to the lower ends of the protection frame, second flange plates are fixedly connected to the upper ends of the sliding rods, and the first flange plates and the second flange plates are fixedly connected by screws and nuts.

[0014] A transportation device includes two sets of lifting hooks symmetrically and fixedly connected to the base body, and a lifting rigging is arranged between two opposite lifting hooks.

[0015] To facilitate improving the efficiency of adjusting the level of the transformer body, further, limiting sliding grooves corresponding to the lifting rigging are symmetrically formed on the protection frame, and the distance between two opposite limiting sliding grooves is greater than the distance between two opposite lifting hooks.

[0016] Compared with the prior art, the present invention provides an adaptive shock-absorbing and buffering transformer installation base, having the following beneficial effects:

[0017] 1. For the transformer installation base with adaptive shock absorption and buffering, the detection plate on one side first contacts the two horizontal support frames. When it is observed manually that the detection plate drives the sliding rod to slide upward relative to the fixed plate by a certain distance, the controller controls the electric telescopic rod to drive the second friction semi-ring to approach the sliding rod, gradually increasing the friction force with the sliding rod until the sliding rod is locked. Then, during the process of the crane continuing to pay out the wire, the other side of the transformer body continues to move downward, causing the detection plate on the other side to contact the horizontal support frame. The inclination angle of the base body is detected in real time through an electronic inclinometer. And when the base body is in a horizontal state, the controller controls the extended electric telescopic rod to contract. At this time, with a certain friction force due to the complete contact between the two detection plates and the horizontal support frames, the transformer body is in a horizontal state. The position of the transformer body is calibrated manually to facilitate fine-tuning of its position. By making the detection plate contact the horizontal support frame first, it is convenient to position it. After adjusting it so that the first mounting hole corresponds to the third mounting hole, a positioning bolt is inserted, thereby realizing the positioning of the base body, effectively improving the positioning efficiency and installation efficiency.

[0018] 2. For the transformer installation base with adaptive shock absorption and buffering, after positioning, by continuing to pay out the wire, the base body moves vertically downward, so that the installation guide rail is clamped onto the vertical support frame, and then bolts are inserted into the second mounting hole and the fourth mounting hole for installation. During the process of lowering the base body, buffering is carried out through the spring, which can prevent the installation guide rail at the lower end of the base body from contacting the vertical support frame first, and the transformer body from impacting the first buffer mechanism due to the influence of inertia force and causing damage.

[0019] 3. For the transformer installation base with adaptive shock absorption and buffering, by pre-calibrating the level of the base body, it can prevent one side of the base body from contacting the ground first after tilting, resulting in excessive local pressure, thereby preventing damage to the first buffer mechanism on one side and the base body. By using the detection plate and the spring to assist in supporting the base body, the local stress on the vertical support frame can be reduced.

[0020] For the parts not involved in this device, they are the same as or can be implemented using the prior art. The present invention effectively improves the positioning efficiency and installation efficiency. By buffering through the spring, it can prevent the installation guide rail at the lower end of the base body from contacting the vertical support frame first, and the transformer body from impacting the first buffer mechanism due to the influence of inertia force and causing damage.

[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments.

[0030] Example 1: Refer to Figures 1 - 7, An adaptive shock-absorbing and buffering transformer installation base, comprising: a base body 1, further comprising: a buffer assembly disposed within the base body 1; a controller 105 disposed within the base body 1; an electronic inclinometer 106 disposed within the base body 1; fixing plates 2 symmetrically and fixedly connected to both sides of the base body 1; sliding rods 201 symmetrically and slidably disposed on the fixing plates 2; a detection plate 202 disposed below the fixing plates 2, and the detection plate 202 is fixedly connected to the lower ends of the two sliding rods 201; springs 203 symmetrically and fixedly disposed between the detection plate 202 and the fixing plates 2, and the springs 203 are sleeved on the sliding rods 201; mounting rails 4 symmetrically and fixedly connected to the lower side of the base body 1; second mounting holes 401 opened on the mounting rails 4; a locking mechanism for locking the sliding rods 201 disposed on the fixing plates 2; first mounting holes 204 symmetrically opened on the detection plate 202.

[0031] The buffer assembly includes at least two groups of first buffer mechanisms 102 symmetrically disposed within the base body 1. A buffer plate 101 is slidably disposed on the upper side of the base body 1, and the buffer plate 101 is fixedly connected to the upper ends of the first buffer mechanisms 102.

[0032] The locking mechanism includes an electric telescopic rod 208 disposed on the detection plate 202, and the output end of the electric telescopic rod 208 is fixedly connected to a second friction semi-ring 209.

[0033] When installing the transformer body 108, the transformer body 108 is welded to the mounting plate 107, and then the mounting plate 107 is installed on the buffer plate 101 through bolts, and the vibration of the transformer body 108 is buffered by the first buffer mechanism 102.

[0034] When installing the transformer body 108, an external crane is needed to lift the base body 1, so as to lift the transformer body 108. The base body 1 is installed on the vertical support frame 503. During the installation process, the crane first hoists the base body 1 together with the transformer body 108 directly above the horizontal support frame 501 and the vertical support frame 503, and then slowly lowers the base body 1 for installation.

[0035] When the base body 1 and the two sides of the transformer body 108 are uneven in weight and inclined during the hoisting process, at this time, the detection plate 202 on one side first contacts the two transverse support frames 501. When an operator observes that the detection plate 202 drives the slide rod 201 to slide upward relative to the fixed plate 2 by a certain distance, the operator sends a control signal to the controller 105 through an external remote controller or a microcomputer. The controller 105 controls the electric telescopic rod 208 on the side in contact with the transverse support frame 501 to extend. The electric telescopic rod 208 drives the second friction semi-ring 209 to approach the slide rod 201, gradually increasing the friction force with the slide rod 201 until the slide rod 201 is locked. Then, during the process of the crane continuing to pay out the wire, the other side of the transformer body 108 continues to move downward, so that the detection plate 202 on the other side contacts the transverse support frame 501. The electronic inclinometer 106 is used to detect the inclination angle of the base body 1 in real time. And when the base body 1 is in a horizontal state, the controller 105 controls the extended electric telescopic rod 208 to contract. At this time, due to the complete contact between the two detection plates 202 and the transverse support frame 501 having a certain friction force, the transformer body 108 is in a horizontal state and its horizontal state is initially restricted. At this time, the operator observes the horizontal signal through the microcomputer, and the operator commands the crane to stop paying out the wire. The position of the transformer body 108 is calibrated manually. Since the transformer body 108 is subjected to the pulling force of the crane and at the same time the base body 1 is not in contact with the transverse support frame 501, it is convenient to finely adjust its position. By the detection plate 202 contacting the transverse support frame 501 first, it is convenient to position it. After adjusting it so that the first mounting hole 204 corresponds to the third mounting hole 502, a positioning bolt is inserted, thereby realizing the positioning of the base body 1, effectively improving the positioning efficiency and the installation efficiency.

[0036] After the positioning is completed, by continuing to pay out the wire, the base body 1 moves vertically downward, so that the installation guide rail 4 is caught on the vertical support frame 503, and then bolts are inserted into the second mounting hole 401 and the fourth mounting hole 504 for installation. During the process of lowering the base body 1, the spring 203 is used for buffering, which can prevent the installation guide rail 4 at the lower end of the base body 1 from first contacting the vertical support frame 503 and then the transformer body 108 being damaged due to the impact of inertia force on the first buffer mechanism 102.

[0037] In actual operation, multiple electric telescopic rods 208 can also be controlled to extend by a specified distance, so that the second friction semi-ring 209 has a certain friction force with the slide rod 201, achieving a better buffering effect.

[0038] By pre-calibrating the level of the base body 1, it can prevent one side of the base body 1 from first contacting the ground and causing excessive local pressure after tilting, thereby preventing damage to the first buffer mechanism 102 and the base body 1 on one side.

[0039] The auxiliary support for the base body 1 through the detection plate 202 and the spring 203 can reduce the local stress on the vertical support frame 503.

[0040] A plurality of second buffer mechanisms 103 are fixedly connected inside the base body 1, and a first gap 104 is provided between the upper end of the second buffer mechanism 103 and the buffer plate 101.

[0041] By providing the second buffer mechanism 103, secondary buffering can be performed on the transformer body 108 to prevent the first buffer mechanism 102 from being excessively squeezed when the transformer body 108 falls. At the same time, by providing the first gap 104 between the second buffer mechanism 103 and the buffer plate 101, it can prevent the second buffer mechanism 103 from affecting the buffering effect of the first buffer mechanism 102 on the vibration of the transformer body 108.

[0042] In the specific implementation manner, by providing the magnetic adsorption type displacement sensor 5, the displacement amount of the detection plate 202 can be detected, so that the relative distance between the lower end of the base body 1 and the vertical support frame 503 can be controlled, preventing the spring 203 from being excessively compressed and affecting the position fine-tuning of the transformer body 108, making it more labor-saving while maintaining horizontal.

[0043] Example 2: Refer to Figures 1 - 7 , an adaptive shock-absorbing and buffering transformer installation base, which is basically the same as Example 1. Further, a first friction semi-ring 205 corresponding to the slide bar 201 is fixedly connected to the detection plate 202.

[0044] By providing the first friction semi-ring 205, a certain frictional force can be provided to the slide bar 201, thereby improving its buffering effect, and the first friction semi-ring 205 can perform lateral limiting on the slide bar 201 to prevent the second friction semi-ring 209 from deforming the slide bar 201 by extrusion.

[0045] A connecting plate 206 is fixedly connected to the detection plate 202, and a connecting sleeve 207 is detachably connected to the connecting plate 206. The electric telescopic rods 208 are symmetrically arranged on both sides of the connecting sleeve 207.

[0046] Among them, the connecting sleeve 207 and the connecting plate 206 can adopt, but are not limited to, the bolt connection method, mainly to facilitate the disassembly of the electric telescopic rods 208 and reduce the equipment cost.

[0047] Example 3: Refer to Figures 1 - 7 , an adaptive shock-absorbing and buffering transformer installation base, which is basically the same as Example 1. Further still, a protective frame 3 is provided between two adjacent slide bars 201, and one side of the protective frame 3 is L-shaped to protect the transformer body 108.

[0048] By setting up the protective frame 3, it is convenient to protect the transformer body 108. At the same time, it is set in an L shape. The L-shaped protective frame 3 has a certain buffering property, and there is a certain gap between two adjacent protective frames 3.

[0049] The lower ends of the protective frame 3 are symmetrically and fixedly connected with first flange plates 301, and the upper ends of the sliding rods 201 are fixedly connected with second flange plates 302. The first flange plates 301 and the second flange plates 302 are fixedly connected by screws and nuts.

[0050] The protective frame 3 is connected to the sliding rod 201 through the first flange plate 301 and the second flange plate 302, so that different protective frames 3 can be set according to the different appearances of the transformer body 108, making its applicability wider.

[0051] Example 4: Refer to Figures 1 - 7 , a transportation device, including a transformer installation base with self-adaptive shock absorption and buffering, two groups of lifting hooks 109 symmetrically and fixedly connected to the base body 1, and a lifting sling 110 arranged between two opposite lifting hooks 109.

[0052] When transporting the transformer body 108, it can be directly hoisted by connecting the sling 110 with a loop to the lifting hook 109. Compared with the current method of threading a rope through and tying a knot first, the hoisting efficiency of the transformer body 108 can be effectively improved.

[0053] When hoisting and loading the transformer body 108 onto a vehicle, its main working principle is basically the same as that of Example 1. When the electronic inclinometer 106 detects that the base body 1 is horizontal, the controller 105 controls the electric telescopic rod 208 to contract, and makes the second friction half-ring 209 have a certain frictional force with the sliding rod 201. During the process of the crane continuing to pay out the wire, the lower end of the base body 1 gradually fits with the carriage of the transport vehicle. And when it tilts again, the tilt angle of the base body 1 is adjusted by the same control method. The sliding rod 201 is buffered by the spring 203, the first friction half-ring 205 and the second friction half-ring 209, so as to effectively prevent the transformer body 108 from being overly pressed against the first buffer mechanism 102 under the action of inertia and causing damage, and enabling it to descend horizontally, thus effectively preventing it from tilting and falling, resulting in excessive local pressure and causing damage to the carriage or the base body 1.

[0054] Example 5: Refer to Figures 1 - 7 , a transportation device, which is basically the same as Example 4. Further, limit sliding grooves 303 corresponding to the lifting sling 110 are symmetrically opened on the protective frame 3, and the distance between two opposite limit sliding grooves 303 is greater than the distance between two opposite lifting hooks 109.

[0055] When hoisting the entire base body 1 and the transformer body 108, the hook of the crane hangs on two hoisting slings 110. When the base body 1 tilts to one side, on the one hand, it may tilt due to the overweight on one side of the transformer body 108, and on the other hand, it may be due to a slight deviation in the hanging position of the crane hook. When the detection plate 202 on one side contacts the carriage and is squeezed to drive the sliding rod 201 to slide upward, the upward-sliding sliding rod 201 drives the protective frame 3 to move upward. The upward-moving protective frame 3 pushes the tilted side of the hoisting sling 110 upward through the limit chute 303, so that the base body 1 can be leveled, thereby effectively improving the hoisting efficiency and safety of the transformer body 108.

[0056] When the transformer body 108 is transported, the large-amplitude vibration of the transformer body 108 can be buffered by the second buffer mechanism 103.

[0057] A second gap 210 is provided between the first friction half-ring 205 and the second friction half-ring 209.

[0058] By providing the second gap 210 between the first friction half-ring 205 and the second friction half-ring 209, it is convenient for the second friction half-ring 209 to better squeeze the sliding rod 201.

[0059] The above is only the preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered within the protection scope of the present invention.
