Description

Technical Field

[0001] The invention belongs to the technical field of leak-plugging devices, and in particular relates to a double-hydraulic oil cylinder compression type leak-plugging module and a use method thereof. Background Art

[0002] Pressurized tank trucks are the primary mode of transport for hazardous chemicals. They are prone to damage due to factors such as rollovers, rear-end collisions, scrapes, corrosion from the medium, weld defects, and damage to sealing materials. This can lead to leaks, combustion, and explosions of hazardous chemicals, resulting in uncontrollable losses to people's lives and property. The tank is the primary site of damage. In the event of a leak in a pressurized tank truck, firefighters typically use bundled plugging tools for emergency sealing. The bundled plugging tool is mainly composed of a plugging block (or plugging module), a rope (wire rope, strap), a rope tensioning-locking device, a power source and its accessories. The method of use is: first, press the plugging block tightly on the leaking part; secondly, tie the rope to the cylinder, with one end of the rope placed in the groove on the outside of the plugging piece, and the other end installed on the rope tensioning-locking device; then connect the power source and its accessories to the rope tensioning-locking device, and then drive the power source to tighten the rope until there is no more leakage; finally, operate the rope tensioning-locking device to limit the rope position, and remove the power source and its accessories.

[0003] The leak-proof block is a key component of the bundled leak-proof tool. Through the leak-proof block, the tension of the rope can be converted into a compression force to achieve emergency sealing. The existing leak-proof block is generally provided with a groove on the outer end face to match the rope, and a leak-proof glue or a sealing gasket is pasted on the inner end face. In order to further improve the compression force, the patent application document with publication number CN 107461605 A discloses a single hydraulic cylinder compression type leak-proof module for a bundled leak-proof tool. The only drawback is that the leak-proof module can only bundle a single rope. When the compression hydraulic cylinder is driven, the leak-proof module may shake, resulting in failure of the sealing. In addition, when used to seal a slit-shaped leak, the sealing failure may also occur due to the uneven compression force applied by the hydraulic cylinder.

[0004] Therefore, there is an urgent need for a method that can effectively increase the compression force of the leak-proof module to meet the emergency needs of the fire brigade to seal the leakage of the cylinder of the pressure tank truck. Summary of the Invention

DETAILED DESCRIPTION

[0036] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below with reference to specific illustrations.

[0037] Due to the problem of sealing failure in the specific application of the existing leak-plugging module, this example provides a dual-hydraulic cylinder compression leak-plugging module. By integrating a miniature dual hydraulic cylinder on the leak-plugging module, the compression force applied to the leak is more evenly distributed; furthermore, multiple ropes can be tied to the leak-plugging module at the same time, avoiding the problem of shaking of the leak-plugging module caused by the operation of the hydraulic cylinder.

[0038] Specifically, such as Figure 1 As shown, the dual hydraulic cylinder compression plugging module 100 provided in this example mainly includes: a base 110 , a hydraulic cylinder sleeve 120 , a hydraulic cylinder 130 , a compression block 140 and a bottom plate 150 .

[0039] The base 110 is mainly used to house the hydraulic cylinder assembly, and is connected to the bottom plate 150 .

[0040] A plurality of bearings are embedded in the upper end surface of the base 110 . The distribution of the bearings on the upper end surface of the base allows the pressing force of the rope on the leak-proof module 100 to be evenly distributed.

[0041] At the same time, the rope tensioning force can be more effectively converted into a compression force through the bearing, and the compression force is always perpendicular to the leak-proof module 100; secondly, it can also effectively avoid the slippage of the leak-proof module 100 caused by the rope tensioning operation.

[0042] In this embodiment, three pairs of bearings are preferably provided. Figure 2 As shown, since the three pairs of bearings are arranged in the same manner, one pair of bearings 111 is selected here for detailed introduction.

[0043] The bearing 111 is embedded in the upper end surface of the base 110 through a connecting bolt, and the connecting bolt is installed on the base 110 through a bearing fixing bolt 113.

[0044] At the same time, in order to facilitate the operator to press the leak-proof module 100 to the leaking part during actual application, this example also provides handles 114 at the left and right ends of the base 110 .

[0045] In specific configuration, the handle 114 is preferably connected to the base 110 via fixing bolts.

[0046] Furthermore, a groove is provided on the base 110 for accommodating the hydraulic cylinder assembly.

[0047] The hydraulic cylinder assembly is mainly used to perform a compression operation on the compression block 140, thereby pressing the sealing glue to the leaking part of the cylinder. It mainly includes: a hydraulic cylinder sleeve 120 and a hydraulic cylinder 130. The hydraulic cylinder 130 is embedded in the inner cavity of the hydraulic cylinder sleeve 120, and the hydraulic cylinder sleeve 120 is embedded on the base 110.

[0048] It is important to note here that if Figure 3 As shown, the hydraulic cylinder sleeve 120 can be embedded with two hydraulic cylinders 130 at the same time, and two hydraulic cylinder mounting holes 121 are provided on it. The base 110 is provided with two base mounting holes 116 corresponding to the two hydraulic cylinder mounting holes 121. The hydraulic cylinder fixing bolts pass through the hydraulic cylinder mounting holes 121 and the base mounting holes 116 to fix the two hydraulic cylinders 130 in the grooves of the base respectively.

[0049] As an example, in the specific setting, threads are provided on the inner cavity of the hydraulic cylinder sleeve 120 and the outer surface of the hydraulic cylinder 130, and the two are screwed together through mutual cooperation through the threads. Such a structural setting enables the hydraulic cylinder 130 to be firmly embedded in the inner cavity of the hydraulic cylinder sleeve 120, and there is no need to worry about it falling off during use, causing unnecessary damage.

[0050] The double hydraulic cylinder compression plugging module 100 is connected to a manual hydraulic pump via a one-way valve, a quick connector, and a hydraulic hose.

[0051] Furthermore, an oil filling hole 122 is provided on the outer side of the hydraulic cylinder sleeve 120 and is connected to the threaded mounting hole 115 provided on the outer side of the base 110 .

[0052] A hydraulic oil circuit 123 is provided inside the hydraulic cylinder sleeve 120 , and an oil filling chamber 124 is formed between the hydraulic oil circuit 123 and the hydraulic cylinder 130 .

[0053] Such a structural arrangement enables the oil filling ports of the two hydraulic cylinders 130 to communicate with the hydraulic oil circuit 123 in the hydraulic cylinder sleeve 120, so that the two hydraulic cylinders 130 can work synchronously.

[0054] The pressing block 140 is connected to the hydraulic cylinder 130 and can perform a pressing operation on the base plate 150 under the drive of the hydraulic cylinder 130 .

[0055] Such an arrangement can not only ensure that the two hydraulic cylinders 130 work synchronously, but also evenly transmit the pressing force of the hydraulic cylinders 130 to the bottom plate 150 .

[0056] The bottom plate 150 is provided with a groove that matches the pressing block 140 and is used to accommodate the pressing block 140 .

[0057] In a specific configuration, the pressing block 140 can be connected to the hydraulic cylinder push rod via the first base plate connecting bolt 112 , and the pressing block 140 can perform a pressing operation on the base plate 150 under the drive of the hydraulic cylinder 130 .

[0058] The bottom plate 150 is used to press and seal the leaking area, and is connected to the base 110 .

[0059] A second bottom plate connecting bolt 117 is provided on the outside of the base 110, and a spring is provided on the second bottom plate connecting bolt 117. The base 110 and the bottom plate 150 are elastically connected through the spring. With such a structural setting, the groove on the bottom plate 150 can be matched with the clamping block 140.

[0060] At the same time, in order to better play the role of sealing, the lower end surface of the bottom plate 150 can also be provided with corresponding sealing gaskets and sealing glue.

[0061] In response to the setting scheme of the dual hydraulic cylinder compression plugging module given above, the method of using the plugging module is further given here. By integrating a miniature dual hydraulic cylinder on the plugging module, the compression force applied to the leak is greatly improved and distributed more evenly, thereby achieving effective plugging.

[0062] The specific operation includes the following steps:

[0063] (1) Setting of sealing components;

[0064] The corresponding leak-proof gaskets and leak-proof glue are arranged on the leak-proof module bottom plate 150;

[0065] (2) Leakage plugging;

[0066] Hold the handle of the plugging block tightly with both hands, align the plugging glue with the center of the leak, and press it to the leaking part;

[0067] (3) Rope setting;

[0073] (6) Hydraulic pump locking operation;

[0074] Operate the manual hydraulic pump, extend the double hydraulic cylinder push rods, and press the sealing glue tightly against the leaking part until the leakage stops.
