[0002] The vertical feed shearing machine is a key equipment in the power reactor reprocessing project. At present, during the final shearing process of the vertical feed shearing machine, it is inevitable that the enclosure of the vertical feed shearing machine's gripper will be deformed when the components are pressed; the seals and other parts in the cylinder part of the gripper that have been used for a long time are easily damaged. Therefore, the gripper of the vertical feed shearing machine is a vulnerable part that needs to be repaired and replaced.

[0003] After the gripper is overhauled or replaced, the feasibility of the gripper's gripping work needs to be verified. However, there is currently a lack of effective equipment on site to inspect the gripper before installation to ensure that the gripper is available. If the gripper installed on the vertical feeding shearing machine is repeatedly hoisted and repaired because the fault is not cleared, it will increase the risk of unnecessary hot chamber environment penetration and personnel radiation, and the long replacement operation will also affect the normal operation of the process production.

[0041] The exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0042] like Figure 1 As shown, an embodiment of the utility model provides a gripping head detection device, comprising:

[0043] Test bench;

[0044] A transmission assembly disposed on the top of the test bench;

[0045] A top rod assembly connected to the bottom of the test bench.

[0046] In this embodiment, the transmission assembly and the push rod assembly are both connected to the test bench, and the gripper performs detection in the area enclosed by the test bench. The transmission assembly can drive the gripper to move up and down, and the push rod assembly is used to open the gripper clamp on the side of the gripper by moving up and down, simulating the coordinated installation of the gripper and the transmission assembly.

[0047] The gripper detection device described in the present application can verify the action of the gripper in the vertical feeding shearing machine after maintenance before installation. There is no need to repeatedly hoist the gripper into the hot chamber for action verification, which shortens the working time and reduces the radiation risk of maintenance personnel. By setting a transmission assembly on the top of the test bench, the height of the gripper can be adjusted, and the external air source can be used to detect the opening and closing action of the gripper jaws. In conjunction with other external devices, it can simulate the stress state of the gripper in the material grabbing process, and play a role in simulating the actual movement of the gripper in the working environment. The transmission assembly cooperates with the test bench to detect whether the gripper panel of the gripper needs to be replaced and simulate the actual movement of the gripper in the barrel. By setting a push rod assembly, the push rod assembly cooperates with the transmission assembly to detect whether the gripper retaining ring of the gripper is tightly connected to the transmission assembly, and plays a role in verifying the state of the retaining ring spring inside the gripper retaining ring.

[0048] In an optional embodiment of the present invention,

[0049] The test bench comprises a base plate 1;

[0050] Side panels 2 vertically connected to both sides of the bottom panel 1;

[0051] A rear plate 3 is vertically connected to the rear end of the bottom plate 1 .

[0052] like Figure 1 As shown, in this embodiment, the bottom plate 1 and the rear plate 3 are both rectangular plates, and the side plates 2 are both triangular plates. The side plates 2 and the rear plate 3 are both fixedly connected to the upper surface of the rear end of the bottom plate 1, and the transmission assembly is arranged on the upper part of the rear plate 3 to adjust the height of the gripping head. The right-angled sides of the side plates 2 are connected to the upper surface of the bottom plate 1 and the two sides of the rear plate 3 to support the rear plate 3. The bottom of the top rod assembly is fixedly connected to the upper surface of the bottom plate 1.

[0053] In an optional embodiment of the present invention,

[0054] The upper surface of the base plate 1 is provided with a simulation body 4;

[0055] The simulation body 4 is a cuboid;

[0056] The side surface of the simulation body 4 is provided with a through slot 41;

[0057] A pin hole 42 is provided at a corner of the upper surface of the simulation body 4 .

[0058] like Figure 3 As shown, in this embodiment, the bottom of the simulation body 4 is fixedly connected to the upper surface of the bottom plate 1, and a through slot 41 is provided on the side of the simulation body 4. At least one side of the simulation body 4 is provided with a through slot 41, and the clamping claw of the gripping head can be inserted into the through slot 41, which plays a role in verifying whether the actual movement of the gripping head is normal, thereby judging whether the clamping claw needs to be replaced or repaired. The pin holes 42 are provided on at least two corners of the upper surface of the simulation body 4, which can allow the conical pin on the gripping head to be inserted, so as to verify whether the gripping head is offset.

[0059] The length of each side of the simulation body 4 is smaller than the length of the corresponding sides of the grab head enclosure, which serves to verify whether the grab head enclosure is deformed.

[0060] In an optional embodiment of the present invention,

[0061] The inner side surface of the rear plate 3 is provided with a slide groove 5, and the opening end of the slide groove 5 is perpendicular to the bottom plate 1;

[0062] The slide groove 5 and the push rod assembly are located on the same straight line.

[0063] In this embodiment, since the slide groove 5 and the push rod assembly are located on the same straight line, the push rod assembly can be adjusted in height so that the grab head clamping ring provided on the side of the grab head can be opened, thereby verifying the coordinated installation action of the grab head clamping ring and the hanging block 8.

[0064] In an optional embodiment of the present invention,

[0065] The transmission assembly includes a winch 6;

[0066] A pulley block connected to the hoist 6 via a steel cable;

[0067] A hanging block 8 connected to the pulley block.

[0068] In an optional embodiment of the present invention,

[0069] The pulley block includes a first pulley 71 connected to the top of the rear plate 3 and a second pulley 72 fixedly connected to the top of the hanging block 8 .

[0070] In an optional embodiment of the present invention,

[0071] The hoist 6 is fixedly connected to the upper end of the outer side surface of the rear plate 3 .

[0072] In the above three embodiments, the hoist 6 is arranged at the top of the outer side of the rear plate 3, and the hoist 6 is wound with a steel cable, which is connected to the pulley block and the suspension block 8 through the steel cable to adjust the height of the suspension block 8. A rotating shaft is arranged on the side of the hoist 6, which can be rotated by a ratchet wrench or an electric wrench to control the hoist 6 to retract and release the steel cable.

[0073] In an optional embodiment of the present invention,

[0074] The hanging block 8 is slidably connected to the slide slot 5;

[0075] The hanging block 8 includes a sliding block 81 slidably connected to the inner surface of the slide groove 5, a connecting block 82 fixedly connected to the lower part of the sliding block 81, and a hanging block 83 fixedly connected to the bottom of the connecting block 82;

[0076] The top of the sliding block 81 is fixedly connected to the second pulley 72;

[0077] The hanging block 83 is an umbrella-shaped structure.

[0078] In the above embodiment, the width of the sliding block 81 is the same as the width of the inner surface of the slide groove 5, so that the sliding block can slide up and down along the slide groove 5. The steel cable connects the winch 6, the first pulley 71, and the second pulley 72 together, and the hanging block 8 moves up and down along the slide groove 5 by rotating the rotating shaft on the side of the winch 6.

[0079] The side surface of the connecting block 82 is fixedly connected to the lower front end of the sliding block 81 and the bottom of the connecting block 82 is fixedly connected to the hanging block 83 , so as to connect the hanging block 83 to the sliding block 81 .

[0080] The hanging block 83 is an umbrella-shaped structure, wherein the rod of the umbrella-shaped structure is fixedly connected to the bottom of the hanging block 83, the inner side of the umbrella surface of the umbrella-shaped structure faces the connecting block 82, and the outer side of the umbrella surface faces the bottom plate 1, which plays the role of fixing the top connecting end of the gripping head.

[0081] The width of the connecting block 82 is determined according to the size of the gripping head, ensuring that when the top connecting end of the gripping head is connected to the hanging block 83, the push rod assembly can support the gripping head clamping ring set on the side of the gripping head.

[0082] By moving the hanging block 8 upwards, the gripping head is suspended in the air, and then external forces are added to the gripping head from all directions, so as to simulate the force conditions of the gripping head in actual work.

[0083] In an optional embodiment of the present invention,

[0084] The ejector assembly comprises an ejector 9;

[0085] A cylinder 10 connected to the bottom of the push rod 9.

[0086] In an optional embodiment of the present invention,

[0087] The top rod 9 includes a rod portion 91 and a rod head 92 connected to the top of the rod portion 91;

[0088] The top of the cylinder 10 is provided with an opening;

[0089] The diameter of the opening is the same as the diameter of the rod portion 91 .

[0090] like Figure 2 As shown, in the above two embodiments, the top of the push rod 9 is fixedly connected with a rod head 92, and the bottom of the push rod 9 is vertically connected with a piston, and the diameter of the piston is the same as the inner diameter of the cylinder 10. A first two-way air valve is provided at the top of the side of the cylinder 10, and a second two-way air valve is provided at the bottom of the side. When in use, gas is injected into the second two-way air valve, and the gas at the top of the piston is discharged from the first two-way air valve. The height of the push rod 9 rises, causing the retaining ring spring in the grabbing head retaining ring to deform, thereby opening the grabbing head retaining ring. Gas is injected into the first two-way air valve, and the gas at the bottom of the piston is discharged from the second two-way air valve. The height of the push rod 9 drops, and the grabbing head retaining ring returns to its position, which serves to verify whether the state of the retaining ring spring in the grabbing head retaining ring is good.

[0091] The diameter of the opening is smaller than the diameter of the cylinder 10 to prevent the push rod 9 from being separated from the cylinder 10 when moving up and down.

[0092] The method of using the gripping head detection device of the utility model is as follows:

[0093] The first step is to connect the top connection end of the gripping head to the hanging block 83, and make the gripping head clamping ring on the side of the gripping head and the push rod assembly in a straight line.

[0094] The second step is to adjust the winch 6 so that the gripping head is at a suitable height. External forces can be applied to different parts of the gripping head through a jack to simulate the actual working environment of the gripping head.

[0095] The third step is to connect an external air source to the gripper to drive the gripper to move and check whether the gripper opens and moves normally.

[0096] The fourth step is to adjust the winch 6 to move the grab head downward and check whether the grab head enclosure can wrap around the outer surface of the simulation body 4. If it can, the grab head enclosure is in good condition and the conical pin of the grab head can be inserted into the pin hole 42. If it cannot, it is necessary to replace the grab head enclosure or adjust the position of the conical pin.

[0097] In the fifth step, after the gripping head is clamped into the simulation body 4, the clamping jaws are controlled to open and close so that the clamping jaws are clamped into the through groove 41, simulating the actual movement of the clamping head grasping the material in the barrel.

[0098] Step 6: Keep the position of the gripping head unchanged, and then raise the height of the top rod 9 in the top rod assembly until the gripping head clamp ring is opened. After the gripping head clamp ring is opened, operate the winch 6 to raise the height of the hanging block 8 and separate the gripping head from the hanging block 8. Keep the height of the top rod 9, operate the winch 6 to lower the height of the hanging block 8, connect the hanging block 8 with the gripping head, then lower the height of the top rod 9 to return the gripping head clamp ring, and finally operate the winch 6 to raise the height of the gripping head, and simulate and verify the coordinated installation action of the gripping head and the hanging block 8.

[0099] The above is a preferred embodiment of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
