Description

Technical Field

[0001] This utility model belongs to the field of heavy equipment installation, and specifically relates to a transformer hydraulic propulsion device. Background Technology

[0002] In the renovation, expansion and maintenance projects of industries such as petrochemicals and coal chemicals, the installation of large transformers and other equipment often faces the challenge of limited site space and the inability to use traditional hoisting equipment such as cranes.

[0003] The traditional method involves placing the transformer on a sliding shoe and using a jacking system consisting of clamps and hydraulic jacks to move the sliding shoe. When the cylinder piston stroke reaches 500mm, the directional valve needs to be operated to release the clamps, allowing the cylinder to retract and reset before continuing to advance.

[0004] In actual use, the clamping force of the clamping pliers may decrease due to hydraulic fluctuations or mechanical wear, affecting the reliability of propulsion.

[0005] Therefore, we propose a transformer hydraulic propulsion device to solve the above problems. Utility Model Content

[0006] To address the problem that traditional methods involve placing the transformer on a sliding shoe and using a jacking system composed of clamping pliers and hydraulic jacks to move the sliding shoe, the clamping force of the clamping pliers may decrease due to hydraulic fluctuations or mechanical wear during actual use, affecting the reliability of the propulsion, this utility model provides a transformer hydraulic propulsion device.

[0007] The solution adopted by this utility model to solve its technical problem is: a transformer hydraulic propulsion device, including a base, a hydraulic cylinder, a slipper, two common seats and two sets of drive components. Two symmetrically arranged guide rails are fixedly installed on the top of the base. The guide rails have internal storage cavities, and N through holes are opened on the opposite sides of the two guide rails respectively.

[0008] The two common seats are respectively set in the storage cavities of the two guide rails, and N stops corresponding to the through holes are fixedly installed on the side of the common seats;

[0009] Two sets of drive components are respectively installed on the opposite sides of the two guide rails. The drive components are connected to the common seat and drive it to move, so that the stop block extends or retracts into the through hole.

[0010] The hydraulic cylinder is positioned between two guide rails. A tail plate is fixedly installed at the tail end of the hydraulic cylinder, and a connecting seat is fixedly installed on its piston rod. The tail plate contacts two opposing stops at the front and rear.

[0011] The sliding shoe is mounted on the guide rail and is detachably connected to the connecting seat.

[0012] Preferably, the drive assembly includes a plurality of cylinders arranged along the length of the guide rail, wherein the piston rods of the cylinders pass through the sidewall of the guide rail and are fixedly connected to a common seat.

[0013] Preferably, the connecting seat is connected to the slipper by bolts or pins.

[0014] Preferably, the width of the tail plate is greater than the distance between the front and rear stops.

[0015] Preferably, the guide rail is made of square steel, and a sliding plate is welded to its top.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. This utility model uses a cylinder and a common seat to make the stop block extend out of the through hole, forming a stable support structure. Compared with the friction clamping method of traditional hydraulic clamping clamps, the cooperation mechanism between the stop block and the tail plate enables the hydraulic cylinder to obtain stable support and reaction force during the advancement process, effectively avoiding the problem of advancement failure caused by the decrease of clamping force, and greatly improving the reliability and safety of the transformer during the advancement process.

[0018] 2. This utility model controls the operation of the hydraulic cylinder. Under the action of the stop block, the piston rod extends to drive the sliding shoe and transformer to move forward. When the stroke of the hydraulic cylinder reaches its limit, the synchronous operation of multiple cylinders is controlled to make multiple stop blocks retract into the through hole at the same time. The hydraulic cylinder can easily retract without obstruction. Thus, after each hydraulic cylinder stroke is completed, the cylinder controls the stop block to extend out of the through hole to form a new fulcrum and realize cyclic propulsion.

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Please see Figure 1-2 This utility model provides a technical solution for a transformer hydraulic propulsion device:

[0024] Example 1:

[0025] according to Figure 1 and Figure 2As shown, it includes a base 1, a hydraulic cylinder 42, a sliding shoe 5, two common seats 32, and two sets of drive components. Two symmetrically arranged guide rails 2 are fixedly installed on the top of the base 1. The guide rails 2 have internal storage cavities. The guide rails 2 are made of square steel and have a sliding plate welded to their top, which enhances the overall load-bearing capacity and stability. N through holes are opened on the opposite sides of the two guide rails 2. The length of the guide rails 2 and the number of through holes are specifically set according to the advancement distance of the transformer.

[0026] Two common seats 32 are respectively set in the storage cavities of the two guide rails 2, and N stops 33 corresponding to the through holes are fixedly installed on the side of the common seats 32.

[0027] Two sets of drive components are respectively set on opposite sides of the two guide rails 2. The drive components include multiple cylinders 31 arranged along the length of the guide rail 2. The piston rod of the cylinder 31 passes through the side wall of the guide rail 2 and is fixedly connected to the common seat 32. By controlling the synchronous operation of multiple cylinders 31, the stop block 33 extends or retracts into the through hole.

[0028] The hydraulic cylinder 42 is positioned between two guide rails 2. A tail plate 41 is fixedly installed at the tail end of the hydraulic cylinder 42, and a connecting seat 43 is fixedly installed on its piston rod. The sliding shoe 5 is positioned on the guide rail 2 and is detachably connected to the connecting seat 43.

[0029] The width of the tail plate 41 is greater than the distance between the two front and rear stops 33. The tail plate 41 contacts the two front and rear opposite stops 33. By controlling the operation of the hydraulic cylinder 42, under the action of the stops 33, the piston rod extends to drive the slipper 5 and the transformer to move forward. When the stroke of the hydraulic cylinder 42 reaches its limit, the cylinder 31 is controlled to make multiple stops 33 retract into the through hole at the same time. The hydraulic cylinder 42 can easily retract without obstruction. Thus, after each stroke of the hydraulic cylinder 42 is completed, the cylinder 31 controls the stops 33 to extend out of the through hole to form a new fulcrum and realize cyclic propulsion.

[0030] This utility model discloses a transformer hydraulic propulsion device. Compared with the friction clamping method of traditional hydraulic clamping clamps, the cooperation mechanism between the stop block 33 and the tail plate 41 ensures that the hydraulic cylinder 42 can always obtain stable support and reaction force during the propulsion process, effectively avoiding the problem of propulsion failure caused by the decrease of clamping force, and greatly improving the reliability and safety of the transformer during the propulsion process.

[0031] Example 2:

[0032] Based on Embodiment 1, the difference is as follows: the connecting seat 43 and the slipper 5 are connected by bolts or pins.
