Description

Technical Field

[0001] The invention relates to the technical field of ship equipment repair, and in particular to a heat exchanger plate transport tool and a transport method. Background Art

[0002] When repairing a plate heat exchanger on a ship, it is often restricted by the on-site passage of the ship, and the heat exchanger cannot be completely disassembled for repair in the factory. The heat exchanger can only be disassembled on the spot at the ship site. After disassembly, hundreds of heat exchange plates need to be hoisted into the factory for cleaning and maintenance. Due to the large number of heat exchange plates, thin wall thickness, and large size, it is extremely important to protect the plates during the hoisting process into the cabin. The plates will be damaged if the hoisting is not careful. Especially for heat exchangers such as central coolers and main engine lubricating oil coolers, the outer dimensions are 1900mm×900mm, the plate thickness is less than 1mm, the number is 300-400 pieces / set, and the material is stainless steel. It is very easy to be damaged and deformed during hoisting, and residual oil will flow down with the plates, polluting the deck passages and other electromechanical equipment.

[0003] Therefore, it is necessary to improve the existing heat exchanger plate transportation technology to solve the above problems. Summary of the invention

[0004] In order to solve the above problems, the present invention proposes a heat exchanger plate transport tooling and a transport method, aiming to improve the safety and environmental protection of heat exchanger plate transportation and protect the heat exchanger plates from damage. The specific technical solution is as follows:

[0005] A heat exchanger plate transport tooling comprises a semi-enclosed box body with an open upper portion, and two pairs of studs vertically arranged upward on the bottom surface of the interior of the box body, the two pairs of studs comprising a left pair of studs located at the left end portion of the interior of the box body, and a right pair of studs located at the right end portion of the interior of the box body; after the heat exchanger plates are stacked and placed in the box body, they are located between the left pair of studs and the right pair of studs, and the stacked heat exchanger plates are pressed and fixed in the box body by a long pressure plate connected between the two pairs of studs; horizontal lifting ears are respectively arranged on the front and rear side walls of the box body, and a vertical lifting ear is arranged on the right outer wall of the box body, and an oil retaining seal is arranged on the left side of the open portion of the box body.

[0006] In order to facilitate the installation of the studs in the box, a number of inverted channel steels with notches facing downward are arranged on the inner bottom surface of the box, and waist-shaped grooves are opened on the inverted channel steels along the length direction of the inverted channel steels. Slider nuts are placed in the open grooves of the inverted channel steels, and the lower ends of the studs pass downward through the waist-shaped grooves and are connected to the slider nut.

[0007] In order to protect the heat exchanger plates from being damaged, the inner bottom surface and the inner surrounding surfaces of the box body are paved with nylon wear-resistant plates.

[0008] Similarly, a nylon tube is jacketed on the outer circle of the stud, and a protective wooden board is arranged between the long pressing plate and the heat exchanger plate.

[0009] As a preferred solution of the present invention, the long strip pressure plate is a channel steel pressure plate, and the channel steel pressure plate is pressed on one side of the heat exchanger plate by the studs and nuts, and an anti-loosening tightening component is arranged at the lower end of the other side of the channel steel pressure plate, and the anti-loosening tightening component includes a column and a pneumatic jack connected to the top of the column, and an elastic rubber block for tightening and preventing loosening is arranged on the top pressure head of the pneumatic jack, and a crank arm is arranged on one side of the column, and a vertical positioning hole is arranged on the crank arm, and the vertical positioning hole of the crank arm is sleeved on the outer circle of the stud.

[0010] As a further improvement of the present invention, a pair of magnetic grip anchors for improving the safety of turning over and rotating the box body are arranged on the left side of the box body, and the magnetic grip anchor includes an anchor seat, a number of anchor claws connected to the lower end of the anchor seat, and a magnetic seat arranged on each anchor claw, and a magnetic switch is arranged on the magnetic seat.

[0011] Preferably, guide rails are arranged on the outer walls on both sides of the front and rear sides of the box body along the left and right directions, and a T-shaped roller groove is built into the guide rail; a horizontally arranged anchor seat hole is opened on the anchor seat, and a support shaft is installed in the anchor seat hole, and a roller is rotatably arranged on the cantilever end of the support shaft, and the roller is rollingly arranged in the T-shaped roller groove; a limit plate is also arranged on the outer circle of the support shaft close to the anchor seat hole, and the limit plate is detachably fixed to the guide rail by screws.

[0012] Preferably, the magnetic seat is rotatably connected to the lower end of the fluke via a hinge shaft.

[0013] Preferably, the hinge axis and the support axis are perpendicular to each other.

[0014] A method for transporting a heat exchanger plate transport tool comprises the following steps:

[0015] (1) Installation of heat exchanger plates: stack the heat exchanger plates and place them in the box, press and fix them, and use anti-loosening and tightening components to reinforce them;

[0016] (2) Preparation before erection and lifting: Turn on the magnetic switch on the magnetic base of the magnetic grip anchor so that the magnetic grip anchor is firmly adsorbed on the steel plate outside the cabin;

[0017] (3) Vertical lifting outside the cabin: Use the hook of the crane to hook the vertical lifting lug on the box body, lift the box body upward to the vertical state, and after confirming that it is safe, turn off the magnetic switch on the magnetic base of the magnetic grip anchor to disengage the magnetic grip anchor from the steel plate site;

[0018] (4) Lifting vertically into the cabin: Lift the vertically erected box into the cabin;

[0019] (5) Preparation before turning over and landing: Turn on the magnetic switch on the magnetic base of the magnetic gripping anchor, and slowly lower the upright box with a crane. The magnetic gripping anchor at the lower end of the box is firmly adsorbed on the steel plate site in the cabin through the magnetic base;

[0020] (6) Turn the box over and onto the ground: After confirming that the site is safe, use a hoist and a crane to slowly turn the box over until it falls horizontally to the ground. After the box falls horizontally to the ground, the heat exchanger plates can be removed from the box and the heat exchanger can be installed.

[0021] In order to be able to safely and dynamically adjust the position of the box during the turning over and landing process, and ensure that the box is accurately positioned in a compact space, during the turning over and landing operation of the box in step (6), the screws of the upper limit plate on the magnetic grip anchor are removed in advance before turning over and landing, so that the rollers on the magnetic grip anchor can roll and shift relative to the box guide rails, and then the lifting hoist is used in conjunction with the lifting crane to slowly turn the box over. While the box is slowly turning over, the lateral displacement of the box is also achieved by the rollers supported on the magnetic grip anchor until the box falls horizontally.

[0022] The beneficial effects of the present invention are:

[0023] First, in the heat exchanger plate transport tooling and transport method of the present invention, the heat exchanger plates stacked in the box are compressed and fixed, and no collision or displacement occurs during hoisting and turning over, thereby well protecting the heat exchanger plates.

[0024] Second, a heat exchanger plate transport tooling and transport method of the present invention has a lifting lug at the end of the box body, and after the box body is filled with plates, it can be lifted upright and transported into the cabin; and because an oil retaining seal is provided on one side of the open part of the box body, when the box body is erected, the residual oil on the plates is intercepted by the oil retaining seal plate and remains in the box body, thereby not contaminating the deck passage and other electromechanical equipment.

[0025] Thirdly, a heat exchanger plate transport tooling and transport method of the present invention can effectively prevent the heat exchanger plates from loosening during the lifting and turning process by means of an anti-loosening and tightening assembly arranged on the studs. On the other hand, the special structure of the anti-loosening and tightening assembly can effectively prevent the heat exchanger plates from being over-tightened, thereby well protecting the heat exchanger plates.

[0026] Fourthly, in a heat exchanger plate transport tooling and transport method of the present invention, the provision of magnetic grip anchors on the box body further improves the safety of lifting and turning over, and the special structure of the magnetic grip anchors enables the safe and dynamic adjustment of the position of the box body during the turning over and landing process, ensuring the accurate positioning of the box body in a compact space.
