In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0024] In the assembly and maintenance of diesel engines, the hoisting and transportation of water jacket components is an essential procedure. Current technology typically uses general-purpose flexible lifting tools such as slings, wire ropes, or nylon slings to secure the water jacket components before lifting. While this method is simple in structure and low in cost, it has the following drawbacks in practical operation: Water jackets are mostly thin-walled, irregularly shaped shells. The slings need to be wound multiple times and the center of gravity needs to be manually adjusted, which is labor-intensive and time-consuming. The contact between the sling and the outer wall of the water jacket is line contact or point contact, resulting in concentrated force. During lifting, turning and lowering, the sling is prone to slippage or local friction, which can cause scratches on the surface of the water jacket or even cause deformation of the thin wall of the water jacket and cracks. Because of the high flexibility of the sling, the water jacket components are prone to swaying in the air, which threatens the safety of the staff and may also cause the water jacket components to collide with other equipment and be damaged.

[0025] To address the aforementioned issues, this application provides a lifting tool for diesel engine water jacket components, which can prevent damage to the diesel engine water jacket components during lifting and improve the stability of the lifting process.

[0026] This application also provides a hoisting system including a hoisting tool for a diesel engine water jacket component.

[0027] The following is for reference. Figures 1 to 6 This application describes a lifting tool for a diesel engine water jacket component according to an embodiment of the present application.

[0028] like Figure 1 and Figure 2 As shown, the X-axis points from left to right horizontally, the Y-axis points from front to back horizontally, and the Z-axis points from bottom to top vertically. It can be understood that the horizontal and vertical directions in this specific embodiment are... Figure 1 and Figure 2 The coordinate axes in the diagram can be clearly represented.

[0029] This application provides a 1000 lifting tool for diesel engine water jacket components. Please refer to [link / reference]. Figure 1 and Figure 2 The lifting tool includes a load-bearing rod 100, a support frame 200, and a first lifting rod 300. The load-bearing rod 100 is fixedly connected to an external lifting device, which can lift the load-bearing rod 100. The support frame 200 includes four support rods 210, which are sequentially hinged end to end to form a quadrilateral shape. Four hinged parts are formed between the support rods 210. The four hinged parts include a first hinged part 220 and a second hinged part 230 located on a diagonal of the support frame 200. The load-bearing rod 100 is hinged to the first hinged part 220. There are two first lifting rods 300. One end of each first lifting rod 300 is hinged to the second hinged part 230, and the other end is bent towards each other to form two bent parts 600.

[0030] In other words, such as Figure 1 As shown, the diesel engine water jacket component lifting tool 1000 includes a load-bearing rod 100, a bracket 200, and a first lifting rod 300, which are connected sequentially from top to bottom. There is one load-bearing rod 100, which supports the weight of the entire tool and the lifted diesel engine water jacket component during lifting operations. The lower end of the load-bearing rod 100 is connected to the bracket 200, which includes four support rods 210 of equal length. These four support rods 210 are hinged end-to-end to form a quadrilateral shape. Because the support rods 210 are of equal length, the bracket 200 also forms a rhombus shape.

[0031] In addition, the support rods 210 are hinged to each other, and four hinge parts are formed at the hinge positions of the support rods 210. Therefore, two hinge parts located on any diagonal of the support 200 can be close to each other or far apart. The four hinge parts include a first hinge part 220 and a second hinge part 230 located on a diagonal of the support 200. That is, the first hinge part 220 and the second hinge part 230 can be close to each other or far apart. The load-bearing rod 100 is specifically hinged to the first hinge part 220 of the support 200.

[0032] Two first suspension rods 300 are connected to the lower part of the support 200. The upper ends of both first suspension rods 300 are hinged to the second hinge portion 230 of the support 200. The first suspension rods 300 can rotate around the second hinge portion 230. The rods of the two first suspension rods 300 have a certain bending angle, and the lower ends of the two first suspension rods 300 are also bent to form bending portions 600. In the same first suspension rod 300, the bending at the rod body and the bending at the lower end are both in the same direction. However, in the two first suspension rods 300, they bend towards each other and form two opposing bending portions 600, respectively. Figure 5 As shown, this arrangement facilitates the rotation of the first boom 300, allowing the bent portions 600 of the two first booms 300 to extend into both ends of the diesel engine water jacket component located between the two first booms 300, so that external lifting equipment can lift the diesel engine water jacket component.

[0033] It is worth noting that, since the first hinge portion 220 and the second hinge portion 230 of the bracket 200 can be close to or far from each other, when it is necessary to lift the diesel engine water jacket component, it is only necessary to use the lifting equipment to transport the diesel engine water jacket component lifting tool 1000 to the horizontal position of the diesel engine water jacket component, and adjust the height position of the diesel engine water jacket component lifting tool 1000 by the adjustable bracket 200. There is no need to use slings to tie around the diesel engine water jacket component and adjust it. This solution is convenient and avoids damage to the diesel engine water jacket component by the slings.

[0034] In some embodiments, such as Figure 4As shown, the diesel engine water jacket component hoisting tool 1000 also includes a locking rod 400. One end of the locking rod 400 is provided with a hinge post 410 for hinged connection, and the other end is provided with a buckle 420 and a slot 430. The buckle 420 includes a pin 421 and a socket. The pin 421 can be inserted into the socket to close the slot 430, and the pin 421 can be removed from the socket to open the slot 430. In other words, one end of the locking rod 400 is provided with a hinge post 410 so that the locking rod 400 can be rotatably installed inside the diesel engine water jacket component hoisting tool 1000, and the other end is provided with a bayonet 430 to fix the components inside the diesel engine water jacket component hoisting tool 1000. The locking rod 400 is provided with a pin 421 and a socket. When the pin 421 is inserted into the socket 422, the bayonet 430 is closed. When the pin 421 is removed from the socket 422, the bayonet 430 is opened. The pin 421 and the socket 422 can realize the opening and closing of the bayonet 430, that is, to realize the fixing and unfixing of the components inside the diesel engine water jacket component hoisting tool 1000.

[0035] Furthermore, the latch 420 includes a spring 423 and a spring fixing part 424. The spring fixing part 424 has a through hole for the pin 421 to pass through. The spring 423 is sleeved on the pin 421, with one end of the spring 423 fixed to the pin 421 and the other end fixed to the spring fixing part 424. When the pin 421 moves out of the insertion port, the pin 421 causes the spring 423 to compress and move towards the spring fixing part 424, thus compressing the spring 423. Figure 4 As shown, the insertion port 422 is located at the rightmost end of the latch 420. The pin 421 can move left and right on the locking bar 400 to insert into or remove from the insertion port 422. A spring 423 is fitted on the pin 421. The right end of the spring 423 is fixedly connected to the pin 421. The locking bar 400 has a spring fixing part 424 at the left end of the spring 423. The spring fixing part 424 has a through hole for the pin 421 to pass through. The left end of the spring 423 is fixed to the spring fixing part 424. When the spring 423 is in a natural extension and retraction state, the pin 421 is inserted into the insertion port 422 to close the latch 430. If it is necessary to open the latch 430, the operator needs to overcome the elastic force of the spring 423 and pull the pin 421 to the left. When the operator no longer applies the pulling force to the pin 421, the pin 421 is reinserted into the insertion port 422 under the action of the spring 423.

[0036] Further, please see Figure 1 One end of the locking rod 400 is hinged to any one of the first lifting rods 300. The other first lifting rod 300, which is not hinged to the locking rod 400, has a first protrusion 310. When the latch 430 of the locking rod 400 is opened, the locking rod 400 can rotate around the first lifting rod 300 to allow the first protrusion 310 to engage with the latch 430. In other words, please refer to... Figure 1 and Figure 4The locking rod 400 is hinged to the first lifting rod 300 on the left side via the hinge post 410 at its left end. The first lifting rod 300 on the right side is provided with a first protrusion 310 corresponding to the slot 430. The operator overcomes the elastic force of the spring 423 and pulls the pin 421 to the left to open the slot 430 and makes the locking rod 400 rotate around the hinge post 410 until the first protrusion 310 is inserted into the slot 430. At this time, the operator releases the pin 421, and the pin 421 is inserted into the slot 422 under the action of the spring 423, thereby fixing the first protrusion 310 and fixing the two first lifting rods 300 so that the two first lifting rods 300 are relatively stationary, so as to ensure that the diesel engine water jacket component lifted by the bent part 600 of the two first lifting rods 300 will not fall off during the lifting process.

[0037] In some embodiments, see Figure 1 and Figure 2 The diesel engine water jacket component hoisting tool 1000 includes a second lifting rod 500, which includes a first rod 510 and a second rod 520. The first rod 510 includes a first rod segment 511 and a second rod segment 512, which are connected at an angle. One end of the first rod 510 is located at the first rod segment 511, and the other end of the first rod 510 is located at the second rod segment 512. The end of the first rod 510 located at the first rod segment 511 is hinged to a second hinge portion 230, and the other end of the first rod 510 located at the second rod segment 512 is hinged to one end of the second rod 520. The other end of the second rod 520 is bent to form a bent portion 600.

[0038] In other words, such as Figure 2 As shown, there is one second lifting rod 500. This second lifting rod 500, together with the two first lifting rods 300, is hinged to the second hinge portion 230 of the bracket 200. The second lifting rod 500 includes a first member 510 and a second member 520, with the first member 510 located above the second member 520. The first member 510 includes a first segment 511 and a second segment 512, which are vertically connected, as shown... Figure 2 As shown, the second boom 500 is hinged to the second hinge portion 230 of the bracket 200 via the first segment 511 of the first member 510. The first segment 511 extends downward in the height direction, while the second segment 512 extends backward in the horizontal direction toward the diesel engine water jacket component lifting tool 1000. The upper end of the second member 520 is hinged to the second segment 512 and can rotate around the second segment 512. The lower end of the second member 520 is bent to form a bent portion 600.

[0039] It is worth noting that, please combine Figure 2 and Figure 6It is understood that the first rod 510 rotates around the second hinge 230 of the bracket 200, and the second rod 520 rotates around the second rod segment 512 of the first rod 510, so that the bent part 600 at the lower end of the second rod 520 can smoothly extend into the through-hole of the diesel engine water jacket component, so as to cooperate with the first lifting rod 300 to lift the diesel engine water jacket component.

[0040] Furthermore, such as Figure 2 As shown, the locking rod 400 is hinged to the second rod segment 512. The second rod 520 is provided with a second protrusion 521. When the latch 430 of the locking rod 400 is opened, the locking rod 400 can rotate around the second rod segment 512 to allow the second protrusion 521 to engage with the latch 430. In other words, please refer to... Figure 2 and Figure 4 The locking rod 400 is hinged to the second section 512 of the second boom 500 via its hinge post 410. The second rod 520 is provided with a second protrusion 521 corresponding to the slot 430. The operator overcomes the elastic force of the spring 423 to pull the pin 421 to open the slot 430 and make the locking rod 400 rotate around the hinge post 410 until the second protrusion 521 is engaged in the slot 430. At this time, the operator releases the pin 421, and the pin 421 is inserted into the slot 422 under the action of the spring 423, thereby fixing the second protrusion 521, and thus fixing the second rod 520 and the first rod 510 together, so that the first rod 510 and the second rod 520 no longer rotate and remain relatively stationary, so as to ensure that the diesel engine water jacket component lifted by the bent part 600 of the second boom 500 will not fall off during the lifting process.

[0041] Furthermore, such as Figure 3 As shown, the diesel engine water jacket component lifting tool 1000 includes a pad 700, which is fixedly installed at the bend 600. The pad 700 provides cushioning and prevents the bend 600 from directly contacting the diesel engine water jacket component. It is understood that the pad 700 can be made of a material with good elasticity, such as rubber or silicone. The pad 700 is installed at the bend 600 of the first lifting rod 300 and the second lifting rod 500, as shown. Figure 3 As shown, the pad 700 is connected to the bent part 600 by threads, and the pad 700 can also be connected by glue or other means.

[0042] Please see Figure 5 and Figure 6This application also provides a lifting system, which includes the aforementioned diesel engine water jacket component lifting tool 1000, support rod 800, lifting ring 900, and lifting equipment (not shown in the figure); the load-bearing rod 100 is connected to the support rod 800, the lifting ring 900 is fixedly installed on the support rod 800, and the lifting equipment can lift the lifting ring 900. Multiple diesel engine water jacket component lifting tools 1000 are provided, and the support rod 800 has slots 810 corresponding to the number of diesel engine water jacket component lifting tools 1000, into which the load-bearing rod 100 can be installed. That is, as... Figure 5 As shown, the support rod 800 has two slots 810, as... Figure 2 As shown, the load-bearing rod 100 of the diesel engine water jacket component lifting tool 1000 is formed into a ring, which can be placed in the support rod 800 along the through groove of the support rod 800, as shown. Figure 5 As shown, the support rod 800 is provided with two lifting rings 900. The lifting rings 900 are used to connect to the lifting equipment. The lifting equipment lifts the support rod 800 through the lifting rings 900, thereby lifting the diesel engine water jacket component lifting tool 1000 and the diesel engine water jacket component located below the support rod 800.
