Description

Technical Field

[0001] The utility model relates to the technical field of sling tooling, in particular to a novel fuel cell engine box sling tooling. Background Art

[0002] At present, the fuel cell engine hoist generally exceeds the upper surface of the engine, encroaching on the vertical installation space of the engine. Therefore, the engine needs to be installed on the vehicle and then hoisted. However, the current hoist is single, which brings unnecessary labor waste when fixing engines of different sizes on the hoist. External tools such as ropes are also needed for fixing and reinforcement, and the installation process is long, resulting in low adjustability of the hoist. Therefore, it is necessary to provide a new type of fuel cell engine box hoist tooling. Utility Model Content

[0003] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a new type of fuel cell engine box lifting fixture, comprising: two structural fixing plates, two circular notches are provided on the top of the two structural fixing plates, a spring clamping mechanism is provided on the structural fixing plates, the circular notches are slidably connected to a hanging plate, one side of the hanging plate is rotatably connected to a special lifting ring, the top of the hanging plate is fixedly connected to a latch rod, one end of the latch rod is connected to a support beam, and a limiting groove is provided on one side of the support beam.

[0004] As a preferred implementation, one end of the latch rod is connected through one side of the structural fixing plate.

[0005] The technical effect of adopting the above-mentioned further scheme is: when the staff needs to fix the engine case, first place the engine case between the structural fixing plates, and then start to move the two structural fixing plates according to the size of the engine case until the engine case is locked. Then, the staff inserts the pin rod at the bottom of the hanging plate through the structural fixing plate, and then inserts it into the inner wall of the limiting groove on one side of the support beam. If it is found that the structural fixing plate cannot find a suitable limiting groove due to irregular size of the generator case, the staff first fixes the structural fixing plate to the bottom of the engine case, and then uses the spring clamping mechanism to fix it, and finally uses the sling to pull the special lifting ring on one side of the hanging plate to move upward.

[0006] As a preferred embodiment, the spring clamping mechanism includes a connecting plate, two connecting plates are fixedly connected to one side of the structure fixing plate, a spring is fixedly connected to one side of the connecting plate, one end of the spring is fixedly connected to a positioning support plate, one side of the positioning support plate is penetrated by a positioning guide plate, the top of the positioning guide plate is fixedly connected to the bottom of the structure fixing plate, a square slot is opened on the top of the structure fixing plate, the inner wall of the square slot is slidably connected with a clamping plate, and the bottom of the clamping plate is fixedly connected to the top of the positioning guide plate.

[0007] The technical effect of adopting the above-mentioned further scheme is: when it is necessary to fix the engine case, the support beam does not have a limit groove in a suitable position. The staff first uses the structural fixing plate at the bottom of the engine case, and then pulls the positioning support plate by hand to a position away from the positioning guide plate, and uses the elastic force of the spring to push the clamping plate to tightly clamp on the outer wall of the engine case. In order to fix the position of the positioning support plate, the positioning support plate can only move forward and backward through the positioning guide plate. At the same time, it also avoids the inconvenience of finding a fulcrum to pry open the clamping plate when the clamping plate needs to be disassembled after being clamped on the engine case. The square notch on the top of the structural fixing plate can prevent the clamping plate from moving freely and can only move forward and backward.

[0008] As a preferred implementation, two second positioning guide blocks and two first positioning guide blocks are fixedly connected to the bottom of the structure fixing plate.

[0009] The technical effect of adopting the above further scheme is: in order to avoid the force of the engine case pressing on the structural fixing plate to be concentrated on the contact surface between the structural fixing plate and the support beam, which may cause the support beam to bend due to the small force area, the two positioning guide blocks 1 and 2 at the bottom of the structural fixing plate are used to increase the force points and reduce the force pressure on the support beam.

[0010] As a preferred implementation, one side of the two support beams is fixedly connected with a support rod.

[0011] The technical effect of adopting the above further solution is: in order to prevent the two support beams from automatically separating, they can be connected and fixed by support rods.

[0012] Compared with the prior art, the advantages and positive effects of the utility model are:

[0013] The utility model solves the problem of low adjustability of the sling through the spring clamping mechanism, the latch rod and the support beam. When the staff needs to fix the engine case, the case is first placed between the top of the support beam and the structure fixing plate, and then the structure fixing plates are moved toward each other according to the size of the case. If a suitable limit groove cannot be found, the structure fixing plates can be placed on the bottom of the case, and then the outer wall of the case can be clamped with the clamping plate and the spring. The operation steps are simple and the adjustability of the sling is increased. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] like Figure 1-2As shown, one end of the latch rod 11 is connected to one side of the structural fixing plate 2. When the staff needs to fix the engine case, first place the engine case between the structural fixing plates 2, and then start to move the two structural fixing plates 2 according to the size of the engine case until the engine case is locked. Then, the staff inserts the latch rod 11 at the bottom of the hanging plate 12 through the structural fixing plate 2, and then inserts it into the inner wall of the limiting groove 10 on one side of the support beam 3. If it is found that the structural fixing plate 2 cannot find a suitable limiting groove 10 due to irregular size of the generator case, the staff first fixes the structural fixing plate 2 to the bottom of the engine case, and then uses the spring clamping mechanism to fix it, and finally uses the sling to pull the special lifting ring 7 on one side of the hanging plate 12 to move upward.

[0021] like Figure 1-2 As shown, the spring clamping mechanism includes a connecting plate 9, one side of the structural fixing plate 2 is fixedly connected to two connecting plates 9, one side of the connecting plate 9 is fixedly connected to a spring 6, one end of the spring 6 is fixedly connected to a positioning support plate 5, one side of the positioning support plate 5 is penetrated and connected to a positioning guide plate 1, the top of the positioning guide plate 1 is fixedly connected to the bottom of the structural fixing plate 2, the top of the structural fixing plate 2 is provided with a square notch 14, the inner wall of the square notch 14 is slidably connected to a clamping plate 15, the bottom of the clamping plate 15 is fixedly connected to the top of the positioning guide plate 1, when the engine case needs to be fixed, the support beam 3 has no suitable position The staff first moves the positioning support plate 5 to a position away from the positioning guide plate 1 through the structural fixing plate 2 at the bottom of the engine case, and then uses the elastic force of the spring 6 to push the clamping plate 15 to be tightly clamped on the outer wall of the engine case. In order to fix the position of the positioning support plate 5, the positioning guide plate 1 is used to make the positioning support plate 5 only move forward and backward. At the same time, it also avoids the inconvenience of finding a fulcrum to pry open the clamping plate 15 when the clamping plate 15 is clamped on the engine case and needs to be disassembled. The square notch 14 on the top of the structural fixing plate 2 prevents the clamping plate 15 from moving freely and can only move forward and backward.

[0022] like Figure 1-2 As shown, two positioning guide blocks 2 8 and two positioning guide blocks 1 4 are fixedly connected to the bottom of the structural fixing plate 2. In order to prevent the force of the engine case pressing on the structural fixing plate 2 from being concentrated on the contact surface between the structural fixing plate 2 and the support beam 3, which may cause the support beam 3 to bend due to the small force-bearing area, the two positioning guide blocks 1 4 and the positioning guide block 2 8 at the bottom of the structural fixing plate 2 are used to increase the force points and reduce the force pressure on the support beam 3.

[0023] like Figure 1-2 As shown, one side of the two support beams 3 is fixedly connected with a support rod 16 . In order to prevent the two support beams 3 from automatically separating, they can be connected and fixed by the support rod 16 .

Then, the staff inserts the pin rod 11 at the bottom of the hanging plate 12 into the inner wall of the limiting groove 10 on one side of the support beam 3. If the support beam 3 does not have a limiting groove 10 in a suitable position so that the structural fixing plate 2 can clamp the case, the staff can first place the structural fixing plate 2 at the bottom of the engine case, and then manually pull the positioning support plate 5 to a position away from the positioning guide plate 1, and use the spring 6 to push the clamping plate 15 to tightly clamp the outer wall of the engine case.
