[0001] This invention relates to the field of engineering, and more particularly to a heavy equipment translation device and its usage method. Background Technology

[0002] In power construction projects, transformers without mobile trolleys are typically positioned using jacks for lifting and horizontal movement. This requires setting up a horizontal movement track and jacks for pushing and moving. To facilitate transformer maintenance, more and more transformers are now equipped with mobile trolleys, enabling rapid relocation. Currently, the most common method is a pulley system combined with a winch, which requires a large working space. Tensioning jacks, on the other hand, are suitable for situations with limited space. Conventional methods no longer meet the demands of modern heavy transformer relocation. There is an urgent need to develop a highly efficient, flexible, and stable traction method and device for relocating heavy transformers with mobile trolleys. Summary of the Invention

The fixing device is fixed to a ground anchor point on the transformer foundation, the ground anchor point being located at the front end of the transformer. The tensioning jack is placed on the fixing device. The transformer trolley is equipped with the connecting device. One end of the steel strand is installed on the tensioning jack, and the other end of the steel strand is installed on the connecting device. The transformer trolley is used to place the transformer. When the tensioning jack extends its cylinder, the steel strand is tightened, thereby enabling the steel strand to pull the transformer trolley to move. The tensioning jack, through repeated cylinder extension and retraction actions, pulls the transformer to a set position on the transformer foundation.

[0005] As a further improvement of the present invention, there are multiple tensioning jacks, which are arranged symmetrically on the transformer base. Two tensioning jacks are placed on each of the fixing devices, and the tensioning jacks are positioned by steel plates on the base.

[0006] As a further improvement of the present invention, the heavy equipment translation device also includes a first single-hole anchor. After the tensioning jack is inserted into the steel strand, a first single-hole anchor is inserted into the front end of the tensioning jack. The direction of the cone head of the tool clamp of the first single-hole anchor is opposite to the traction direction of the transformer. When the tensioning jack extends its cylinder, it can clamp and traction the steel strand.

[0007] As a further improvement of the present invention, the heavy equipment translation device also includes a second single-hole anchor. After the tensioning jack is inserted into the steel strand, the second single-hole anchor is placed at the rear end of the tensioning jack. The direction of the cone head of the tool clamp of the second single-hole anchor is opposite to the traction direction of the transformer. The second single-hole anchor acts as a tensioning device for the steel strand when the tensioning jack is retracted.

[0008] As a further improvement of the present invention, the connecting device is provided with a through hole, and the other end of the steel strand passes through the front end and the rear end of the transformer trolley, extends into the through hole and connects with the third single-hole anchor. The tool clamp cone of the third single-hole anchor faces the same direction as the transformer traction direction.

[0009] As a further improvement of the present invention, the heavy equipment translation device also includes a steel pipe, and the connecting device is fixed to the lifting lug hole of the transformer trolley through the steel pipe.

[0010] As a further improvement of the present invention, the heavy equipment translation device also includes ground anchor pins, and the fixing device is fixed to the ground anchor point on the transformer foundation by the ground anchor pins, and the number of ground anchor pins is two.

[0011] As a further improvement of the present invention, the heavy equipment translation device also includes a damage prevention material, which is disposed between the steel strand and the transformer foundation, and is used to prevent the transformer foundation from being damaged; the damage prevention material is cloth strips or wooden boards.

[0012] As a further improvement of the present invention, the heavy equipment translation device also includes a spring for fixing the second single-hole anchor between two vertical steel plates on the connecting device; the first single-hole anchor is an M15.2 single-hole anchor; the tensioning jack is a through-hole tensioning jack, and there are four through-hole tensioning jacks and four steel strands; the heavy equipment translation device also includes a jack hydraulic pump station.

[0013] The present invention also discloses a method for using a heavy equipment translation device, comprising the following steps:

[0014] Step 1: Fix the fixing device to the ground anchor point on the transformer foundation with two ground anchor pins respectively. Place two tensioning jacks on one fixing device and position them with the steel plate on the base.

[0015] Step 2: After the tensioning jack is inserted into the steel strand, a first single-hole anchor is inserted into the front end of the tensioning jack. The cone head of the tool clamp of the first single-hole anchor is opposite to the traction direction of the transformer. When the tensioning jack extends its cylinder, it clamps and pulls the steel strand.

[0016] Step 3: Place the second single-hole anchor behind the tensioning jack. The cone head of the tool clamp of the second single-hole anchor is opposite to the traction direction of the transformer and is fixed between the two vertical steel plates by a spring. Its function is to tension the steel strand when the tensioning jack retracts.

[0017] Step 4: Pass the steel strand from the front end of the transformer trolley to the other end of the transformer trolley, and then through the through hole of the connecting device. The connecting device is fixed to the lifting lug hole of the transformer trolley through the steel pipe. After the steel strand passes through the through hole on the connecting device, it is connected to the third single-hole anchor. The conical head of the tool clamp of the third single-hole anchor faces the same direction as the transformer traction direction. When the tensioning jack cylinder is extended, the steel strand is tightened, and the third single-hole anchor and the connecting device are pressed together, so that the steel strand can drive the transformer trolley to move.

[0018] Step 5: Install tarpaulin and wooden boards between the steel strand and the transformer foundation.

[0019] Step 6: Connect the hydraulic oil pump station to the oil pipe of the tensioning jack. When the tensioning jack extends its cylinder, the top and tail of the tensioning jack are positioned by the base.

The tensioning jack 4, through repeated cylinder extension and retraction actions, pulls the transformer 6 to a set position on the transformer foundation 7.

[0028] The tensioning jacks 4 are multiple in number and are arranged symmetrically on the transformer foundation 7. Two tensioning jacks 4 are placed on each of the fixing devices 3. The tensioning jacks 4 are positioned by steel plates on the base.

[0029] The heavy equipment translation device also includes a first single-hole anchor. After the tensioning jack 4 is inserted into the steel strand 1, a first single-hole anchor is inserted into the front end of the tensioning jack 4.

When the tensioning jack 4 extends its cylinder, it can clamp and traction the steel strand 1.

[0030] The heavy equipment translation device also includes a second single-hole anchor. After the tensioning jack 4 is inserted into the steel strand 1, the second single-hole anchor is placed at the rear end of the tensioning jack 4. The direction of the cone head of the tool clamp of the second single-hole anchor is opposite to the traction direction of the transformer 6. The second single-hole anchor is used to tension the steel strand 1 when the tensioning jack 4 is retracted.

[0031] The connecting device 8 is provided with a through hole. The other end of the steel strand 1 passes through the front end and the rear end of the transformer trolley 5 and extends into the through hole to connect with the third single-hole anchor.

[0038] The heavy equipment translation device also includes a jack hydraulic pump station.

[0039] Job Description:

[0040] The main equipment and tools include a through-type tensioning jack, a hydraulic pump station for the jack, steel strand 1, a fixing device 3, and a connecting device 8. The through-type tensioning jack is a hydraulic jack that inserts into the steel strand 1 and uses a hydraulic cylinder to extend and retract the steel strand 1 to achieve the horizontal movement of the heavy equipment. The hydraulic pump station provides hydraulic power to the tensioning jack 4. The steel strand 1 serves as the connecting tool between the through-type tensioning jack and the heavy equipment. The fixing device 3 is used to fix the tensioning jack 4, serving both a fixing and guiding function. The connecting device 7 connects to the lifting lugs of the heavy equipment transformer trolley 5 via a steel pipe, inserts into the steel strand 1, and uses anchors for fixation, thus achieving the horizontal movement of the equipment.

[0041] The present invention also discloses a method for using a heavy equipment translation device, comprising the following steps:

[0042] Step 1: Fix the fixing device 3 to the ground anchor point on the transformer foundation 7 through two ground anchor pins 2. Place two tensioning jacks 4 on one fixing device 3 and position them through the steel plate on the base.

[0043] Step 2: After the tensioning jack 4 is inserted into the steel strand 1, an M15.2 first single-hole anchor is inserted into the front end of the tensioning jack 4. The direction of the cone head of the tool clamp of the first single-hole anchor is opposite to the traction direction of the transformer 6. When the tensioning jack 4 extends its cylinder, it clamps and pulls the steel strand 1.

[0044] Step 3: Place the second single-hole anchor behind the tensioning jack 4. The cone head of the tool clamp of the second single-hole anchor is opposite to the traction direction of the transformer 6 and is fixed between the two vertical steel plates by a spring. Its function is to tension the steel strand when the tensioning jack 4 retracts, and to prevent the steel strand 1 from retracting and sagging due to the retraction of the tensioning jack 4, which would reduce the effective stroke of the next cylinder extension.

[0045] Step 4: The steel strand 1 can be passed from the front end of the transformer trolley 5 to the other end of the transformer trolley 5 and then into the through hole of the connecting device 8. The connecting device 8 is fixed to the lifting lug hole of the transformer trolley 6 through a steel pipe. After the steel strand 1 passes through the through hole of the connecting device 8, it is connected to the third single-hole anchor. The cone head of the tool clamp of the third single-hole anchor faces the same direction as the traction direction of the transformer 6. When the tensioning jack 4 extends, the steel strand 1 is tightened, and the third single-hole anchor is squeezed against the connecting device (8), so that the steel strand 1 can drive the transformer trolley 5 to move. The tensioning jack 4 and the steel strand 1 are configured in the same way on both sets of transformer trolleys 5.

[0046] Step 5: Corrugated tarpaulin, wooden boards, etc. are placed between the steel strand 1 and the transformer foundation 7 to protect the transformer foundation 7 and prevent damage to it.

[0047] Step 6: Connect the hydraulic oil pump station to the oil pipe of the tensioning jack 4. When the tensioning jack 4 extends its cylinder, the top and tail of the tensioning jack 4 are positioned by the base. The cone of the tensioning jack 4 pushes the first single-hole anchor in front, the first single-hole anchor clamps and drives the steel strand 1, so that the steel strand 1 can pull the transformer 6 to move.

[0048] Step 7: Repeat the extension and retraction of the cylinder of the tensioning jack 4 until the transformer 6 is pulled onto the transformer foundation 7 and aligned with the longitudinal and transverse center positions of the transformer foundation 7.

[0049] Specifically, taking the translation of a transformer as an example, the transformer weighs 360t, has external dimensions of 10.3m×3.7m×5m, and the transformer trolley is 1.2m high. A heavy equipment translation device is used to achieve the translation and positioning.

[0050] First, modeling and analysis calculations are performed based on the structural dimensions proposed in the transformer foundation design document 7 to determine the length, the position of the through-type tensioning jack, and to formulate the layout plan for the translation device.

[0051] Assembly of through-hole tensioning jacks: According to the set layout of the translation device, the fixing device 3 is fixed to the ground anchor point on the transformer foundation 7 by two ground anchor pins 2. Two through-hole tensioning jacks are placed on one fixing device 3 and positioned by the steel plate on the base.

[0052] Steel strand 1 assembly: After the through-type tensioning jack inserts the steel strand 1, an M15.2 single-hole anchor (first single-hole anchor) is inserted at the front end of the through-type tensioning jack. The cone head of the tool clamp of the single-hole anchor is opposite to the traction direction of the transformer 6. When the through-type tensioning jack extends its cylinder, it clamps and pulls the steel strand 1. A single-hole anchor (second single-hole anchor) is also placed behind the through-type tensioning jack. The cone head of the tool clamp of the single-hole anchor is opposite to the traction direction of the transformer 6 and is fixed between the two vertical steel plates on the connecting device 8 by a spring. Its function is to tension the steel strand 1 when the through-type tensioning jack retracts its cylinder, preventing the steel strand 1 from retracting and sagging, which would reduce the effective stroke of the through-type tensioning jack when it extends its cylinder next time.

[0053] Assembly of Fixing Device 3: The steel strand 1 passes from the front end of the transport trolley to the other end and through the through hole on the connecting device 8. The connecting device 8 is fixed to the lifting lug hole of the transformer trolley 5 through a steel pipe. After passing through the through hole of the connecting device 8, the steel strand 1 is connected to the third single-hole anchor. The cone head of the tool clamp of the third single-hole anchor faces the same direction as the traction direction of the transformer 6. When the core-type tensioning jack extends its cylinder, the steel strand 1 is tightened, and the third single-hole anchor is squeezed against the connecting device 8, so that the steel strand 1 can drive the transformer trolley 5 to move. The core-type tensioning jack, steel strand 1, and connecting device are configured in the same way on both sets of transformer trolleys 5.

[0054] Connecting and debugging the hydraulic pump station of the through-hole jack: After the setup is completed, connect the hydraulic oil pump station to the oil pipe of the through-hole tension jack. After connecting, conduct a no-load test, let it stand for 5 minutes, and start the horizontal movement after confirming that there is no leakage in the oil pipe and oil seal.

[0055] The calculation method is as follows:

[0056] Through-type tension jack load rate:

[0057] Using four 25t tensioning jacks, with a maximum resistance of f=30t, the load factor is:

[0058] η = 30t / 4 / 25t × 100% = 30% < 80% (Safe)

[0059] Strength check of prestressed steel strand 1:

[0060] Ø15.2 If the rated lifting capacity of a single prestressed steel strand 1 is no more than 10t, and the maximum resistance during traction is 30t, and four steel strands 1 are used during traction, then the force on a single steel strand 1 is:

[0061] 30t / 4=7.5t <10t (safe).

[0062] The beneficial effects of this invention are: 1. The heavy equipment translation device of this invention uses a through-type tension jack, which is conducive to achieving precise positioning of equipment in narrow spaces and realizing synchronous traction; 2. The heavy equipment translation device of this invention can flexibly adjust the number and arrangement of through-type tension jacks according to the weight, size, site conditions, and anchor points of the equipment, and then select the length of the steel strand 1 according to the distance of the equipment foundation anchor points. The stress value of the steel strand is within the allowable range of the specification during the entire process of equipment translation.

[0063] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such modifications and substitutions should be considered within the scope of protection of the present invention.
