Description

Technical Field

[0001] The invention relates to a container ship cargo hold vent cap installation jig, which belongs to the technical field of vent cap installation. Background Art

[0002] The main function of the container ship cargo hold vent cap is to achieve ventilation in the cargo hold. During the sea transportation, the air in the cargo hold will become dirty for various reasons, such as the respiration of the cargo itself (if it is loaded with living goods such as agricultural products), the smell of the cargo, or the condensation of water vapor caused by the temperature difference between the inside and outside of the cargo hold. The vent cap allows fresh air to enter the cargo hold and exhausts the dirty air at the same time, thereby ensuring good air quality in the cargo hold and maintaining a good storage environment for the goods. At the same time, the vent cap also helps to regulate the temperature and humidity in the cargo hold. The marine environment is changeable, and if the temperature and humidity in the cargo hold are not controlled, it may cause damage to the cargo. The vent cap can balance the temperature and humidity inside and outside the cargo hold to a certain extent through ventilation and air exchange, preventing such situations from happening.

[0003] The vent cap generally has a solid shell and is heavy. For container ship cargo hold vent caps, they are generally installed by crane before loading in sections. Disadvantages of this method: Crane lifting and installation are shaky, unstable, and bumpy, and are easily affected by weather and cannot be installed. The installation efficiency is low, the time is long, and the use of large cranes causes waste of resources. Summary of the invention

[0004] In order to solve the problems existing in the prior art, the present invention provides a container ship cargo hold vent cap installation jig, which is specially used for such vent cap installation operations and is convenient and efficient to implement the installation.

[0005] The technical solution adopted by the present invention is: a container ship cargo hold ventilator cap installation fixture, which includes a load-bearing tray and a fork tray, a rotating column and a rotating column sleeve are arranged between the two, the rotating column is fixed to the bottom surface of the load-bearing tray, and the rotating column sleeve is fixed to the front surface of the fork tray. The cooperation between the rotating column and the rotating column sleeve enables the load-bearing tray and the fork tray to rotate relative to each other;

[0006] The two ends of the load-bearing tray are provided with end limit columns, the rear side of the load-bearing tray is provided with a rear limit high column, and the front side of the load-bearing tray is provided with a front limit short column and a movable limit high column;

[0007] The bottom surface of the load-bearing tray is fixed with a rotating wheel connecting plate, the rotating wheel connecting plate is provided with a rotating wheel, and the rotating wheel acts on the fork tine tray;

[0008] A support column is fixed on the fork tine pallet, and the top end of the support column is in contact with the bottom surface of the load-bearing pallet; and a fork tine groove for forklift transportation is arranged on the bottom surface of the fork tine pallet.

[0009] The jig is also provided with a fixing pin which passes through the load-bearing tray and the fork tine tray.

[0010] The length of the rear limiting high column is greater than the length of the front limiting short column, and the length of the movable limiting high column is greater than the length of the front limiting short column.

[0011] The movable limiting high column is arranged on the load-bearing tray through threads, so as to facilitate quick installation and removal of the load-bearing tray.

[0012] The load-bearing tray is also provided with sleepers for shock absorption and supporting the ventilation hood.

[0013] Compared with the prior art, the present invention has the following advantages: it includes a load-bearing tray and a fork-tooth tray, and a rotating column and a rotating column sleeve are arranged between the two. The cooperation of the rotating column and the rotating column sleeve enables the load-bearing tray and the fork-tooth tray to rotate relative to each other, and the rotating wheel is used to rotate and increase the support for the load-bearing tray. The fixing pin ensures that the ventilating cap keeps the load-bearing tray and the fork-tooth tray from rotating during the travel of the forklift. When the ventilating cap is transferred to the installation fixture, the movable limit high column is removed. After the ventilating cap is completely transferred to the fixture, the movable limit high column is quickly installed on the load-bearing tray to limit the ventilating cap and prevent it from falling. The top of the support column contacts the bottom surface of the load-bearing tray, which can support the deformation of the load-bearing tray caused by the gravity of the ventilating cap; the two are only in contact but not fixed, in order to facilitate the relative rotation between the load-bearing tray and the fork-tooth tray. By using the fixture to install the ventilating cap, the installation process is convenient, the stability is good, the operation is fast, the installation process is flexible, it is not affected by the weather, the safety is improved, and the crane resources are saved.

[0027] Figures 1 to 3 A container ship cargo hold vent hood installation fixture is shown, which includes a load-bearing pallet 1 and a fork pallet 13, with a rotating column 10 and a rotating column sleeve 11 arranged between the two. The rotating column 10 is fixed to the bottom surface of the load-bearing pallet 1, and the rotating column sleeve 11 is fixed to the front surface of the fork pallet 13. The cooperation between the rotating column 10 and the rotating column sleeve 11 enables the load-bearing pallet 1 and the fork pallet 13 to rotate relative to each other.

[0028] End limit columns 6 are set at both ends of the load-bearing tray 1, a rear limit high column 2 is set on the rear side of the load-bearing tray 1, and a front limit short column 4 and a movable limit high column 5 are set on the front side of the load-bearing tray 1; the load-bearing tray 1 is also provided with sleepers 3 for shock absorption and supporting the ventilation hood.

[0029] A rotating wheel connecting plate 8 is fixed to the bottom surface of the load-bearing tray 1, and a rotating wheel 9 is provided on the rotating wheel connecting plate 8. The rotating wheel 9 acts on the fork-tine tray 13; the rotating wheel is used to cooperate with the load-bearing tray 1 and the fork-tine tray 13 to rotate relative to each other, and to increase support for the load-bearing tray 1.

[0030] A support column 12 is fixed on the fork tray 13, and the top of the support column 12 is in contact with the bottom surface of the load-bearing tray 1; a fork groove 14 for forklift transportation is provided on the bottom surface of the fork tray 13. The top of the support column 12 is in contact with the bottom surface of the load-bearing tray 13, and can support the deformation of the load-bearing tray caused by the gravity of the ventilating hood; the two are only in contact but not fixed, in order to facilitate the relative rotation between the load-bearing tray and the fork tray.

[0031] The fixture is also provided with a fixing pin 7, which passes through the load-bearing tray 1 and the fork-tine tray 13. The fixing pin 7 ensures that the ventilating cap keeps the load-bearing tray and the fork-tine tray from rotating during the travel of the forklift.

[0032] The length of the rear limit high column 2 is greater than the length of the front limit short column 4, and the length of the movable limit high column 5 is greater than the length of the front limit short column 4. The length of the front limit short column 4 is shorter to facilitate the placement or removal of the ventilating cap on the fixture.

[0033] The movable limit high column 5 is set on the load-bearing tray 1 through a thread, and is installed and removed from the load-bearing tray 1. When the ventilating cap is transferred to the installation jig, the movable limit high column is removed. After the ventilating cap is completely transferred to the jig, the movable limit high column is quickly installed on the load-bearing tray to limit the ventilating cap and prevent it from falling.

[0034] When using the above solution, remove the movable limit high column 5, and then place the ventilator cap on the load-bearing tray 1; then quickly rotate the movable limit high column 5 onto the load-bearing tray 1, ensuring that the ventilator cap is inside the rear limit high column 2, the end limit column 6, the front limit short column 4 and the movable limit high column 5, and limit the ventilator cap to prevent it from falling. Then install the fixing pin 7, insert it into the load-bearing tray 1 and the fork tray 13, use the fork of the forklift to insert the fork groove 14 to lift the fixture, use the forklift to fork the fixture together with the ventilator cap, and move it to the installation position, ready for installation (such as Figure 4 as shown).

[0035] Move the fork to the corresponding installation position, open the fixing pin 7, and release the fixing of the load-bearing tray 1 and the fork tray 13. Through the cooperation of the rotating wheel 9, the rotating column 10 and the rotating column sleeve 11, the load-bearing tray 1 is rotated relative to the fork tray 13. When it is adjusted to a suitable angle, the ventilating cap is installed, and the ventilating cap and the base (flange connection form) are fixed with bolts. The working diagram of the fixture after rotation is as follows: Figure 4 shown.
