Description

Technical Field

[0001] The invention relates to the technical field of building repair, and in particular to a self-balancing repair device and method for cracks in a transformer substation infrastructure. Background Art

[0002] With the continuous expansion of the power system and the rising demand for electricity, substations are being built in various regions. Substations are places in the power system that transform voltage and current, receive and distribute electric energy, and play a very important hub role.

[0003] However, during the construction and operation of substations, factors such as insufficient brickwork materials and construction quality, temperature changes, and rainwater erosion can cause cracks in the concrete structure of substations, especially in some coastal areas. Cracks not only affect the appearance and overall performance of the structure, but may also become channels for water and salt to intrude, accelerate structural corrosion, and affect the reliability of power facilities.

[0004] The existing technology mainly uses colloid to seal the cracks, but the cracks themselves are small and the residue inside the cracks is difficult to clean effectively. Moreover, the glue injection pressure alone will cause it to overflow on its own, and the internal closed cavity cannot be effectively injected. Summary of the invention

[0005] The technical problem to be solved by the present invention is to provide a self-balancing repair device and method for cracks in a transformer substation infrastructure, so as to assist in implementing glue injection without dead angles inside cracks in the infrastructure and ensure the reliability of power facilities.

[0006] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0007] A self-balancing repair device for cracks in a transformer substation infrastructure, comprising a clamping and fixing device, a connecting frame, an expansion component and at least two glue injection auxiliary parts;

[0008] The clamping device comprises a left clamping member and a right clamping member opposite to each other, the clamping force of the clamping device is adjustable, the expansion assembly is connected to the clamping device through the connecting frame, and the left clamping member and the right clamping member are used to clamp two sides of a side of the substation infrastructure where the crack is located;

[0009] The conical movable end of the expansion assembly can be movably arranged relative to the connecting frame, and the conical movable end of the expansion assembly is used to insert into and expand the crack of the substation infrastructure;

[0010] All of the glue injection auxiliary parts are used to be clamped at different positions on the crack opening.

[0011] In order to solve the above technical problems, another technical solution adopted by the present invention is:

[0012] A self-balancing repair method for cracks in a substation infrastructure is applied to the above-mentioned self-balancing repair device for cracks in a substation infrastructure, comprising the following steps:

[0013] S1. Clamp and fix the clamping device on both sides of the side where the crack exists on the substation infrastructure to fix the equipment;

[0014] S2, controlling the tapered movable end of the expansion component to be pressed into the crack, so that the crack expands slightly, and inserting the glue injection auxiliary parts at different positions on the crack mouth;

[0015] S3, cleaning the inside of the crack and sealing the crack mouth except for the conical movable end of the expansion component and the glue injection auxiliary component;

[0016] S4, injecting structural colloid into the crack, gradually increasing the clamping force of the clamping fixture, and adjusting the expansion component each time the clamping force of the clamping fixture is increased to ensure that the tension applied to the crack by the tapered movable end of the expansion component maintains a dynamic balance with the clamping force of the clamping fixture;

[0017] S5. After the structural colloid inside the crack is cured, the expansion component and the glue injection auxiliary component are removed, and the positions of the crack opening corresponding to the conical active end of the expansion component and the glue injection auxiliary component are filled with glue and sealed.

[0025] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in combination with the implementation modes and the accompanying drawings.

[0026] Please refer to Figure 1 and Figure 2 , a self-balancing repair device for cracks in a substation infrastructure, comprising a clamping and fixing device, a connecting frame 3, an expansion component and at least two glue injection auxiliary parts 4;

[0027] The clamping device comprises a left clamping member 1 and a right clamping member 2 which are opposite to each other. The clamping force of the clamping device is adjustable. The expansion assembly is connected to the clamping device through the connecting frame. The left clamping member 1 and the right clamping member 2 are used to clamp two sides of a side of the substation infrastructure where the crack is located.

[0028] The conical movable end of the expansion component can be movably arranged relative to the connecting frame 3, and the conical movable end of the expansion component is used to insert into and expand the crack of the substation infrastructure;

[0029] All of the glue injection auxiliary parts 4 are used to be clamped at different positions on the crack opening.

[0030] From the above description, it can be seen that the beneficial effects of the present invention are: the entire equipment is fixed on the substation infrastructure by using a clamping and fixing device, and the conical active end of the expansion component is aligned with the crack of the substation infrastructure, and then the expansion component is controlled to be inserted into the crack and slightly expand the crack to avoid the crack being too narrow and affecting the effective cleaning of the internal residue. When injecting glue, the dynamic balance between the tension applied by the expansion component and the clamping force of the clamping and fixing device is achieved through adjustment, so that the injection pressure and the clamping pressure jointly help the structural colloid overflow the crack, so as to achieve dead-angle injection inside the crack and ensure the reliability of the power facilities.

[0031] Further, the clamping and fixing device includes a transmission member 5;

[0032] The left clamping member 1 and the right clamping member 2 are disposed on the transmission member 5 , and the left clamping member 1 and the right clamping member 2 can move in a direction of being relatively close to or away from each other on the transmission member 5 .

[0033] From the above description, it can be seen that the left clamping member 1 and the right clamping member 2 move on the transmission member 5 to achieve a clamping process of approaching each other or a loosening process of moving away from each other. This is not only stable in operation, but also convenient for adjusting the clamping force through the transmission member 5.

[0034] Furthermore, the connecting frame 3 includes a first connecting member 31 and a second connecting member 32;

[0035] One end of the first connecting member 31 is hinged to the right clamping member 2, one end of the second connecting member 32 is hinged to the left clamping member 1, the other end of the first connecting member 31 is hinged to the other end of the second connecting member 32, and the expansion component is arranged at the connection point between the first connecting member 31 and the second connecting member 32.

[0036] From the above description, it can be seen that the first connecting member 31, the second connecting member 32 and the transmission member 5 form a triangular structure, and the movement of the right clamping member 2 and the left clamping member 1 can be used to affect the shape of the triangular structure, so that the change in the clamping force affects the position change of the expansion component, and the change in the active position of the conical active end of the expansion component is combined with the adjustment flexibility of the self-balancing to improve the linkage effect of the self-balancing.

[0037] Further, the expansion assembly includes a linear drive member and a conical head 6;

[0038] The conical head 6 is arranged on the movable end of the linear drive member, and the linear drive member is arranged on the connecting frame 3 .

[0039] From the above description, it can be seen that the expansion component is composed of a linear drive and a conical head 6. By controlling the linear drive, the position of the conical head 6 can be adjusted to change the tension applied to the crack, which is easy to operate.

[0040] Further, the linear drive member includes a mounting seat 7 and a screw rod 8;

[0041] The mounting seat 7 is provided with a threaded through hole, the screw rod 8 is threadedly connected to the threaded through hole, and the conical head 6 is arranged on one end of the screw rod 8 close to the clamping and fixing device.

[0042] From the above description, it can be seen that the screw rod 8 controls the directional movement of the conical head 6 through the threaded through hole on the mounting seat 7, and the threaded structure can be used to finely adjust the movement stroke to improve the stability and reliability of the expansion force control.

[0043] Furthermore, there are more than two of the clamping and fixing device, the connecting frame 3 and the expansion assembly.

[0044] From the above description, it can be seen that there are more than two clamping and fixing devices, connecting frames 3 and expansion components to cope with some long lengths or other situations where different positions of the infrastructure need to be clamped, thereby improving the applicability of the equipment.

[0045] Furthermore, it also includes a third connecting member 9;

[0046] One of the third connecting members 9 is detachably connected to the left clamping members 1 of different clamping and fixing devices, and another of the third connecting members 9 is detachably connected to the right clamping members 2 of different clamping and fixing devices.

[0047] It can be seen from the above description that when there are a large number of clamping and fixing devices, connecting frames 3, etc., by providing a third connecting member 9, the stability of the entire device after being used on the infrastructure can be improved.

[0048] Furthermore, the glue injection auxiliary component 4 is provided with an observation hole for observing the inside of the crack.

[0049] From the above description, it can be seen that by setting up the observation hole, the effect of crack glue injection can be easily observed to ensure the quality of glue injection.

[0050] Please refer to Figure 3 A self-balancing repair method for cracks in a substation infrastructure is applied to the above-mentioned self-balancing repair device for cracks in a substation infrastructure, comprising the following steps:

[0051] S1. Clamp and fix the clamping device on both sides of the side where the crack exists on the substation infrastructure to fix the equipment;

[0052] S2, controlling the tapered movable end of the expansion component to press into the crack, so that the crack slightly expands, and inserting the glue injection auxiliary component 4 at different positions on the crack mouth;

[0053] S3, cleaning the inside of the crack and sealing the crack mouth except for the conical movable end of the expansion component and the glue injection auxiliary component 4;

[0054] S4, injecting structural colloid into the crack, and adjusting the expansion component and the clamping device at the same time to ensure that the tension applied by the conical movable end of the expansion component on the crack and the clamping force of the clamping device maintain dynamic balance;

[0055] S5. After the structural colloid inside the crack is cured, the expansion component and the glue injection auxiliary component 4 are removed, and the positions of the conical active end of the expansion component and the glue injection auxiliary component 4 on the crack opening corresponding to the glue are filled and sealed.

[0056] From the above description, it can be seen that the beneficial effects of the present invention are: the entire equipment is fixed on the substation infrastructure by using a clamping and fixing device, and the conical active end of the expansion component is aligned with the crack of the substation infrastructure, and then the expansion component is controlled to be inserted into the crack and slightly expand the crack to avoid the crack being too narrow and affecting the effective cleaning of the internal residue. When injecting glue, the dynamic balance between the tension applied by the expansion component and the clamping force of the clamping and fixing device is achieved through adjustment, so that the injection pressure and the clamping pressure jointly help the structural colloid overflow the crack, so as to achieve dead-angle injection inside the crack and ensure the reliability of the power facilities.

[0057] Further, the removal of the expansion assembly and the glue injection auxiliary component 4 is specifically as follows:

[0058] The expansion assembly is controlled to retract, and the clamping force of the clamping and fixing device is increased until all the glue injection auxiliary parts 4 are squeezed out.

[0059] From the above description, it can be known that the clamping force of the clamping and fixing device is increased until all the glue injection auxiliary parts 4 are squeezed out, and the pressing force is maintained to facilitate subsequent glue filling and ensure the repair quality.

Then, two or more sets of tooling can be set up on the same surface of the substation infrastructure, or they can be set up on different surfaces of the substation infrastructure, depending on actual needs.
