Description

Technical Field

[0001] This utility model belongs to the field of cargo positioning and locking technology, and more specifically, it relates to a hydraulic locking device for positioning heavy cargo on ships. Background Technology

[0002] During the transportation of heavy marine cargo, the ship is easily affected by wind and waves, causing it to sway. Therefore, a reliable positioning and locking device is needed to secure the cargo. Existing marine cargo positioning devices mostly use a single clamping or binding method, which is not stable enough and the cargo is easy to shift. Some devices have clamping parts made of metal, which can easily scratch and damage the surface of the cargo. Moreover, it is difficult to quickly detect if the screws used for fixing in the device become loose, which may lead to locking failure and pose a safety hazard. Utility Model Content

[0003] To address the aforementioned technical problems, this utility model provides a hydraulic locking device for positioning heavy cargo on ships, thereby solving the problems of poor fixing stability, easy damage to cargo, and difficulty in detecting loose screws in existing ship cargo positioning devices.

[0004] The purpose and effect of this utility model of a hydraulic locking device for positioning heavy cargo on ships are achieved by the following specific technical means: A hydraulic locking device for positioning heavy cargo on a ship includes a fixed base; there are two fixed bases, each fixed to the ship by four fixing screws, each fixed base has a sliding base block, each base block has a pressing block fixed inside, each fixed base has a first hydraulic cylinder, and the protruding ends of the two first hydraulic cylinders are respectively fixed to the two base blocks.

[0005] Furthermore, both extrusion blocks are rectangular block structures, and both extrusion blocks are made of wood.

[0006] Furthermore, each of the base blocks has two second hydraulic cylinders hinged to its upper end face, and each second hydraulic cylinder has a connecting seat fixed to its extended end. A steel wire rope is connected to the two front connecting seats, and a steel wire rope is also connected to the two rear connecting seats.

[0007] Furthermore, each of the base blocks is welded with two guide rods, with the two guide rods on the left sliding on a fixed seat on the left, and the two guide rods on the right sliding on a fixed seat on the right.

[0008] Furthermore, the base block, extrusion block, first hydraulic cylinder, guide rod, second hydraulic cylinder, connecting seat, and wire rope together form a locking part; each of the fixing screws has an adjustment groove at its adjustment point, and the adjustment groove has a hexagonal groove structure.

[0009] Furthermore, each of the fixing seats is provided with four auxiliary slots, all of which are cylindrical slot structures. The fixing screws are hidden in the auxiliary slots, and the upper end face of the fixing screws is flush with the bottom end face of the base block.

[0010] Compared with the prior art, the present invention has the following beneficial effects: This application features a double locking mechanism for enhanced stability: The first hydraulic cylinder drives the base block to clamp the cargo from the side, while the second hydraulic cylinder retracts to pull the steel wire rope to bind the cargo from the top. This combination of lateral and top locking significantly improves the stability of the cargo and effectively prevents cargo displacement caused by ship swaying.

[0011] This application offers excellent protection and prevents damage: the compression block is made of wood, which, compared to traditional metal clamping blocks, can prevent scratches and compression damage to the surface of the goods. It is especially suitable for heavy goods with fragile surfaces. At the same time, the elasticity of wood can improve the fit with the surface of the goods and optimize the clamping effect.

[0012] This application features a reliable structure that is easy to maintain: the guide rod restricts the movement direction of the base block, ensuring accurate clamping position and improving structural stability; the fixing screw is hidden in the auxiliary groove and flush with the bottom surface of the base block, making it easy to detect when the screw is loose, facilitating timely tightening by staff and reducing the risk of locking failure; the hexagonal adjustment groove facilitates the disassembly and adjustment of the fixing screw, making maintenance highly convenient.

[0022] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples.

[0023] Example 1: As shown in the attached document Figure 1 To be continued Figure 6 As shown: This utility model provides a hydraulic locking device for positioning heavy cargo on ships, including a fixed base 1; there are two fixed bases 1, each fixed base 1 is fixed to the ship by four fixing screws 101, a base block 201 slides on each fixed base 1, a pressing block 202 is fixed inside each base block 201, and a first hydraulic cylinder 203 is fixed on each fixed base 1. The extended ends of the two first hydraulic cylinders 203 are respectively fixed on the two base blocks 201. When fixing the cargo, the cargo is placed between the two base blocks 201, and the two first hydraulic cylinders 203 are driven to extend. The two first hydraulic cylinders 203 drive the base blocks 201 and the pressing block 202 to move inward. The two pressing blocks 202 can complete the pressing and fixing of the cargo.

[0024] Both compression blocks 202 are rectangular block structures and are made of wood. When the goods are tightened and fixed by the compression blocks 202, the wooden compression blocks 202 can reduce the damage to the goods.

[0025] Each base block 201 has two second hydraulic cylinders 205 hinged to its upper end. Each second hydraulic cylinder 205 has a connecting seat 206 fixed to its extended end. A steel wire rope 207 is connected to the two front connecting seats 206 and a steel wire rope 207 is also connected to the two rear connecting seats 206. When fixing the goods, the steel wire rope 207 is placed on top of the goods, driving the four second hydraulic cylinders 205 to retract. Under the pulling action of the four second hydraulic cylinders 205, the goods can be fixed again through the steel wire rope 207. Through double fixing, the fixing efficiency is higher.

[0026] Each base block 201 is welded with two guide rods 204. The two guide rods 204 on the left slide on a fixed seat 1 on the left, and the two guide rods 204 on the right slide on a fixed seat 1 on the right. During use, the connection between the guide rods 204 and the fixed seat 1 can improve the firmness of the connection between the base block 201 and the fixed seat 1 and reduce the probability of the base block 201 detaching from the fixed seat 1.

[0027] The base block 201, the extrusion block 202, the first hydraulic cylinder 203, the guide rod 204, the second hydraulic cylinder 205, the connecting seat 206, and the wire rope 207 together form the locking part 2; each fixing screw 101 has an adjustment groove 102 at its adjustment point. The adjustment groove 102 is a hexagonal groove structure. When assembling or disassembling the fixing screw 101, it can also be disassembled or assembled through the adjustment groove 102.

[0028] Example 2: Based on Example 1, each fixing base 1 is provided with four auxiliary slots 103. The four auxiliary slots 103 are all cylindrical slot structures. The fixing screws 101 are all hidden in the auxiliary slots 103. The upper end face of the fixing screws 101 is flush with the bottom end face of the base block 201. During use, when the fixing screws 101 become loose, it will affect the left and right movement of the base block 201, which makes it easier for personnel to detect the loosening of the fixing screws 101 in time and avoid the adverse effects caused by the loosening of the fixing screws 101.

[0029] Working principle: When using this device to position and lock heavy cargo on a ship, firstly, fix the two fixing seats 1 to the designated positions on the hull using the fixing screws 101 to ensure that the fixing seats 1 are firmly installed; then, hoist the heavy cargo to be fixed between the two base blocks 201, so that the cargo is in the center position of the device; then, activate the two first hydraulic cylinders 203, the extended ends of the first hydraulic cylinders 203 push the base blocks 201 to slide along the fixing seats 1, and the guide rods 204 slide synchronously to ensure that the base blocks 201 move in the correct direction, until the wooden pressing blocks 202 on both sides are tightly attached to the side walls of the cargo, completing the lateral clamping of the cargo; then, the steel wire ropes 207 on the front and rear connecting seats 206 are attached to the cargo. Protective sleeves can be installed on the steel wire rope 207 at both ends of the top of the goods to prevent damage. Activating the four second hydraulic cylinders 205 retracts their extended ends, pulling the steel wire rope 207 taut to secure the top of the goods, forming a double locking mechanism. During operation, staff should periodically observe the status of the fixing screw 101 in the auxiliary groove 103. If the screw is found to be loose, use a hex wrench to tighten it through the adjusting groove 102. When unloading the goods, first activate the second hydraulic cylinder 205 to extend the extended ends and release the steel wire rope 207. Then activate the first hydraulic cylinder 203 to retract the extended ends, moving the base block 201 and the pressing block 202 away from the goods. Finally, the goods can be hoisted away.
