Description

Technical Field

[0001] This utility model relates to the field of hoisting equipment technology, and in particular to a hoisting device for a compaction tank. Background Technology

[0002] A compaction tank is a device used to compress or compact materials, commonly found in industrial production and waste treatment. In use, it typically compresses the tank and the waste inside into a patty through squeezing or pressing to reduce volume. In nuclear waste treatment plants, the waste temporarily stored in compaction tanks, due to its radioactivity, usually requires no human contact during transportation. Therefore, a high degree of automation is necessary, and the transport line must be designed according to actual needs.

[0003] Chinese Patent CN 117968342 A discloses a drying system for intermediate and high-level radioactive solid waste and a radioactive waste disposal system, and discloses a transfer device for transporting compacted containers containing intermediate and high-level radioactive waste to a dryer device. Specifically, the transfer device includes components such as a transfer track, a transfer trolley, and grippers. The grippers include a gripping mechanism and a lifting mechanism. The lifting mechanism is installed on the transfer trolley, and the gripping mechanism is adapted to the compacted container and installed on the lifting mechanism. The gripping mechanism is used to grip the compacted container, and the lifting mechanism is used to drive the gripping mechanism to rise to load the compacted container into the transfer trolley and to drive the gripping mechanism to fall to unload the compacted container into a drying drum.

[0004] The aforementioned patent does not disclose the specific structure of the gripping and lifting mechanisms. However, due to different transport routes, the specific structure of the gripping and lifting mechanisms may vary. Utility Model Content

[0005] The technical problem to be solved by this utility model is to design a new type of lifting device for compaction tanks. This lifting device has a stable structure, reasonable design, and is suitable for use in various types of compaction tanks.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a hoisting device for a compaction tank, comprising a hoisting mechanism and a gripping mechanism, wherein the hoisting mechanism and the gripping mechanism are connected by a lifting plate, and the gripping mechanism includes support components symmetrically arranged at both ends of the bottom center position of the lifting plate, the support components being connected to the lifting plate through support vertical beams, a support beam being fixedly connected between the two support components, and movable components being provided at both ends of the support beam, the movable components being movable on the support beam, one end of the support beam being connected to a power mechanism, the movable components being fixedly connected to a crossbeam, and grippers being fixedly connected to the bottom ends of the crossbeam through connecting vertical beams.

[0007] Furthermore, two linear rails are arranged opposite each other on the hanging plate, the linear rails are located at both ends of the crossbeam, and the linear rails are connected to the upper part of the crossbeam through sliders.

[0008] Furthermore, a positioning beam is provided at the bottom center of the hanging plate to prevent the compaction tank from contacting the hanging plate.

[0009] Furthermore, the power mechanism includes an electric wrench for outputting power, the output end of which is connected to a hollow reducer via a conversion connector, and the conversion connector is connected to the output end of the electric wrench via a positioning sleeve.

[0010] Furthermore, the hollow speed reducer is connected to a support beam, the support beam being a positive and negative lead screw, and the moving component being a nut that mates with the lead screw.

[0011] Furthermore, the gripper is equipped with an anti-slip pad inside.

[0012] Furthermore, the hoisting mechanism includes a lifting lug at the top, the bottom of which is fixedly connected to a load-bearing crossbeam, both ends of which are connected to load-bearing vertical beams, and the bottom of which is connected to a hoisting plate.

[0013] Furthermore, the load-bearing vertical beam is connected to the load-bearing horizontal beam via lugs.

[0014] Beneficial effects: This application uses an electric wrench to control the rotation of a hollow reducer, which drives the forward and reverse screws to rotate, thereby moving the nut on the screws to achieve the clamping and loosening of the gripper. Then, the compaction tank is transported to the required position by a hoisting mechanism to achieve compression, and the compressed cake is clamped, hoisted and transported.

[0015] Meanwhile, considering the rigidity of the gripping action and gripping structure, the gripper is fixed on a linear rail, providing an upward pulling force to the gripper and further preventing it from breaking.

[0016] The hoisting device of this application is simple and reasonable in design, highly safe, and applicable to the hoisting of different types of tanks, and has wide application value. Attached Figure Description

Detailed Implementation

[0022] To enhance understanding of this utility model, it will be described in detail below with reference to the embodiments and accompanying drawings. These embodiments are only used to explain this utility model and do not limit the scope of protection of this utility model.

[0023] like Figure 1 and Figure 2 The image shows a hoisting device for a compaction tank, which specifically includes a hoisting mechanism and a gripping mechanism, wherein the hoisting mechanism and the gripping mechanism are connected by a lifting plate 1.

[0024] The gripping mechanism includes support components 2 symmetrically arranged at both ends of the bottom center of the suspended platform 1. The support components 2 are connected to the suspended platform 1 via support vertical beams 3, thereby fixing them to the bottom of the suspended platform 1. A support beam 4 is fixedly connected between the two support components 2. Movable components 5 are provided at both ends of the support beam 4, and the movable components 5 can move back and forth on the support beam 4.

[0025] The moving component 5 is fixedly connected to the crossbeam 7. The bottom ends of the crossbeam 7 are fixedly connected to the gripper 9 through the connecting vertical beam 8. By moving the moving component 5 back and forth repeatedly, the gripper 9 can be clamped and released. It can also be adapted to compaction tanks of different diameters.

[0026] According to a preferred embodiment of this utility model, the support beam 4 is a positive and negative lead screw, and the moving component 5 is a nut that cooperates with the lead screw. One end of the lead screw is connected to the power mechanism 6, allowing the nut to move back and forth on the lead screw.

[0027] The aforementioned power mechanism 6 includes an electric wrench 61 for outputting power. The output end of the electric wrench 61 is connected to the hollow reducer 63 via a conversion connector 62. The conversion connector 62 is connected to the output end of the electric wrench 61 via a positioning sleeve 64.

[0028] Of course, other designs can be chosen for the support beam and the moving component, such as a slider and guide rail design, as long as the moving component can move repeatedly on the support beam. In this case, the power mechanism can be a cylinder-driven mechanism.

[0029] Because the gripping action and rigidity of the gripping structure are prone to breakage, it is considered to fix the gripper on a linear guide to provide an upward pulling force and further prevent breakage. Therefore, two linear guides 10 are arranged opposite each other at the bottom of the hanging plate 1. The linear guides 10 are located at both ends of the crossbeam 7 and are connected to the protruding parts on the crossbeam 7 by sliders 101. The sliders 101 can slide on the linear guides, thereby providing corresponding sliding and support when the moving component drives the crossbeam 7 to move.

[0030] A positioning beam 11 is provided at the bottom center of the hanging plate 1 to prevent the upper surface of the compaction tank 12 from contacting the hanging plate 1, thereby damaging the compaction tank.

[0031] According to a preferred embodiment of the present invention, such as Figure 1 As shown, two positioning beams 11 are symmetrically arranged with the center of the bottom of the hanging plate 1 as the center. Alternatively, one beam can be arranged at the center, or four beams can be arranged symmetrically, as long as the balance of the entire system is maintained.

[0032] According to a preferred embodiment of the present invention, such as Figure 3 As shown, in order to increase the friction coefficient and toughness of the gripper during gripping, an anti-slip pad 91 is provided inside the gripper 9. The anti-slip pad can be a nylon pad.

[0033] like Figure 1 As shown, the hoisting mechanism includes a lifting lug 13 at the top, the bottom of which is fixedly connected to a load-bearing crossbeam 14. Both ends of the load-bearing crossbeam 14 are connected to load-bearing vertical beams 15, and the bottom of the load-bearing vertical beams 15 is fixedly connected to the hoisting plate 1.

[0034] like Figure 4 As shown, the load-bearing vertical beam 15 is connected to the load-bearing horizontal beam 14 via the lug 16.

[0035] In use, the hollow reducer is rotated by an electric wrench, which drives the forward and reverse screws to rotate, thereby moving the nut on the screws to achieve the clamping and loosening of the gripper. Then, the compaction tank is transported to the required position by the hoisting mechanism to achieve compression, and the compressed cake is clamped, hoisted and transported.

[0036] The embodiments disclosed herein are preferred embodiments, but are not limited thereto. Those skilled in the art can readily grasp the spirit of this utility model based on the above embodiments and make different extensions and variations. However, as long as they do not depart from the spirit of this utility model, they are all within the protection scope of this utility model.
