Description

Technical Field

[0001] The utility model relates to the technical field of transformer production, in particular to a sand filling tool for a transformer oil tank reinforcement beam. Background Art

[0002] In the production process of transformers, in order to improve the strength of the transformer oil tank, reinforcement beams are usually welded on the tank wall. In this way, a cavity will be formed between the reinforcement beam and the tank wall; based on the requirements for noise during the operation of the transformer, the reinforcement beam needs to be filled with sand.

[0003] At present, the commonly used sand filling method is: place a funnel at the opening of the reinforcing beam, and then cooperate with two people, one person is responsible for holding the funnel, and the other person uses a shovel to shovel sand from the sand filling bucket and pour it into the funnel; the sand flows into the reinforcing beam through the funnel to complete the sand filling. With this operation method, the sand filling efficiency is very low; and as the size of the transformer becomes larger and larger, the reinforcing beam becomes higher from the ground. During the sand filling process, the operator needs to use tools such as shovels to operate in an area about 2 meters high, which poses a great safety hazard. In addition, during the sand filling process, it is necessary to constantly use shovels to shovel and pour sand, which has a high labor intensity for the staff, and dust is easily generated during sand filling, which has a certain degree of impact on the workshop working environment. Utility Model Content

[0004] The present application provides a sand filling tool for reinforcing beams of transformer oil tanks to overcome the above-mentioned problems existing in the prior art. The sand filling tool for reinforcing beams of transformer oil tanks of the present application is provided with a sand outlet at the lower end of the sand filling bucket, and a limit baffle is provided at the sand outlet. At the same time, a specific drainage structure is provided inside the sand filling bucket by utilizing the flow characteristics of the sand material, so that when performing the sand filling operation, it is only necessary to open the limit baffle to allow the sand material to slide down autonomously under the action of gravity to fall into the funnel below, and the operation method is simplified, which greatly improves the work efficiency and reduces the labor intensity; compared with the original two people cooperating to perform high-altitude operations, now only one operator is needed to operate the limit baffle, the labor cost is low, and the operation height can be reduced to below 1.5 meters, which improves the safety of the operation; in addition, the sand transportation path is shortened, so that the diffusion of dust in the workshop is also effectively controlled.

[0005] The technical solution of this application is:

[0006] The sand filling tooling for the transformer oil tank reinforcement beam comprises a sand filling bucket; the top of the sand filling bucket is open, and a sand outlet is provided at the lower end; a limit baffle is provided at the sand outlet for blocking the sand; a main baffle is inclined inside the sand filling bucket, one end of the main baffle is connected to the side plate of the sand filling bucket, and the other end is connected to the bottom plate of the sand filling bucket and is close to the sand outlet; two auxiliary baffles are symmetrically provided on the main baffle, and the two auxiliary baffles are distributed on both sides of the sand outlet; the auxiliary baffle is inclined relative to the main baffle; a cavity is formed between the main baffle, the auxiliary baffle and the side plate of the sand filling bucket for storing sand; when the limit baffle is opened, the sand in the cavity will flow downward under the action of gravity and flow out from the sand outlet.

[0007] Compared with the prior art, the sand filling tooling structure design of the transformer oil tank reinforcement beam of the present application is ingenious. It uses the fluidity and gravity characteristics of the sand to simplify the sand filling operation, which can not only significantly improve the working efficiency, but also ensure the safety of the working process; the sand filling tooling is provided by opening a sand outlet at the lower end of the sand filling bucket, and setting a limit baffle at the sand outlet, and at the same time, the main baffle and the auxiliary baffle are tilted inside the sand filling bucket (the setting of the auxiliary baffle can prevent the sand from accumulating at the bottom of the front end of the sand filling bucket) to form a specific drainage structure, so that when performing the sand filling operation, only the limit baffle needs to be opened to allow the sand to slide down autonomously under the action of gravity to fall into the funnel below (the funnel is set on the reinforcement beam), which greatly improves the work efficiency and reduces the labor intensity; compared with the original two people cooperating to perform high-altitude operations, now only one operator is needed to operate the limit baffle, the labor cost is low, and the working height can be reduced to below 1.5 meters, which improves the working safety; in addition, the sand transportation path is shortened, so that the diffusion of dust in the workshop is also effectively controlled.

[0008] As an optimization, in the aforementioned transformer oil tank reinforcement beam sand filling tooling, the inclination angle α between the main baffle and the bottom plate is 35-60°; the inclination angle β between the auxiliary baffle and the main baffle is 35-60°. At this time, it can ensure that the sand material falls freely under the action of gravity, and can also prevent the sand material from falling too fast from rushing out of the sand outlet and spilling on the ground.

[0009] As an optimization, in the aforementioned transformer oil tank reinforcement beam sand filling tooling, the sand filling bucket is in a rectangular parallelepiped shape, the sand outlet is arranged on the front side plate of the sand filling bucket, and the auxiliary baffle is in a triangular shape. Thus, the installation and distribution of the main baffle and the auxiliary baffle in the sand filling bucket are convenient and easy to implement.

[0010] As an optimization, in the aforementioned sand filling tooling for the transformer oil tank reinforcement beam, the limit baffle is L-shaped, including a transverse limit plate and a longitudinal slide; the front side plate of the sand filling bucket is provided with a first limit block and two second limit blocks located on both sides of the sand outlet; the first limit block is located above the transverse limit plate, and is used to limit the moving position of the limit baffle; a slide groove is formed between the second limit block and the side plate, and is used for the longitudinal slide to slide; the distance D between the transverse limit plate and the first limit block is less than the height H of the limit baffle. At this point, the structure is simple and easy to assemble; when filling sand, the sand filling port can be opened by simply moving the limit baffle upward, and the operation is very simple.

[0011] Furthermore, the ratio between the distance D between the transverse limit plate and the first limit block and the height H of the limit baffle is 0.75 to 0.8. Therefore, when the limit baffle moves up and is blocked by the first limit block, part of the lower end of the longitudinal slide (1 / 5 to 1 / 4 of the part) is still in the chute, and the sand material will generate thrust when it flows out, which ensures that the limit baffle will not fall. Furthermore, the limit baffle is integrally formed by bending. At this time, the structure is simple and easy to manufacture.

[0012] As an optimization, in the aforementioned transformer oil tank reinforcement beam sand filling tooling, the bottom of the sand filling bucket is provided with a foot for supporting the entire sand filling bucket. Thus, when the sand filling bucket is placed on the transformer oil tank cover, the bottom of the sand filling bucket can be suspended in the air, thereby avoiding interference between the sand filling bucket and some parts on the oil tank cover. Furthermore, the foot includes two spaced channel steels. The channel steel has high strength, can withstand greater pressure and weight during use, and is not easily deformed; thus, it can ensure that the sand filling bucket has high stability and reliability.

[0013] As an optimization, in the aforementioned sand filling tooling for the transformer oil tank reinforcement beam, the first limit block, the second limit block and the foot are respectively welded and fixed to the sand filling bucket. At this time, the connection between the first limit block, the second limit block, the foot and the sand filling bucket has high reliability, high rigidity and good integrity, so that during the sand filling process, the limit block and the foot will not loosen, and the safety factor is high.

[0014] As an optimization, in the aforementioned transformer oil tank reinforcement beam sand filling tooling, a group of spaced hanging holes are respectively provided at the upper ends of the left and right side plates of the sand filling bucket. During the sand filling operation, the hanging rope can be installed in the hanging hole, and then the sand filling bucket can be lifted and moved by a crane, which is more convenient to operate.

DETAILED DESCRIPTION

[0021] The present application is further described below in conjunction with the accompanying drawings and embodiments, but they are not intended to limit the present application.

[0022] In order to facilitate the efficient and safe delivery of sand to a designated location during sand filling operations, the applicant provides a sand filling tool for a transformer oil tank reinforcement beam. The sand filling tool incorporates the fluidity and gravity characteristics of sand into the structural design of the sand filling bucket 1, and designs a main baffle 3 and an auxiliary baffle 4 inside the sand filling bucket 1 to form a specific drainage structure, so that the sand can flow downward by itself when there is a gap, thereby improving the operating efficiency.

[0023] Practice has proved that this innovative solution has achieved remarkable results in improving operational safety, reducing costs, shortening working hours, etc. Specifically: the traditional operation method requires two people to work together (one person holds the funnel, and the other person uses a shovel to fill sand) to fill a 200mm wide reinforced beam with sand, which takes about 15 minutes. However, after using the sand filling tooling of the present application, it only takes one person to complete the task, and the sand filling time for the same reinforced beam is shortened to less than 5 minutes, and the operating efficiency is increased by 5-6 times; and the original high-altitude operation, now the operator only needs to operate the limit baffle 2, and the operating height is reduced to below 1.5 meters, thereby improving the safety of the operation; in addition, the sand transportation path is shortened, and the diffusion of dust in the workshop is also effectively controlled.

[0024] Example (see Figure 1 to Figure 5 ):

[0025] The sand filling tool for reinforcing beam of transformer oil tank comprises a sand filling bucket 1; the top of the sand filling bucket 1 is open, and a sand outlet 101 is provided at the lower end; a limit baffle 2 for blocking sand is provided at the sand outlet 101; a main baffle 3 is inclinedly provided inside the sand filling bucket 1, one end of the main baffle 3 is connected to the side plate 11 of the sand filling bucket 1, and the other end is connected to the bottom plate 12 of the sand filling bucket 1 and is close to the sand outlet 101; the inclination angle α between the main baffle 3 and the bottom plate 12 is 4 0°; two auxiliary baffles 4 are symmetrically arranged on the main baffle 3, and the two auxiliary baffles 4 are distributed on both sides of the sand outlet 101; the auxiliary baffle 4 is inclined relative to the main baffle 3, and the inclination angle β between the auxiliary baffle 4 and the main baffle 3 is 40°; a cavity 102 is formed between the main baffle 3, the auxiliary baffle 4 and the side plate 11 of the sand filling bucket 1 for storing sand; when the limit baffle 2 is opened, the sand in the cavity 102 will flow downward under the action of gravity and flow out from the sand outlet 101.

[0026] In this embodiment, the sand filling bucket 1 is in the shape of a rectangular parallelepiped, and the sand outlet 101 is arranged on the front side plate 11 of the sand filling bucket 1; the auxiliary baffle 4 is triangular, and the three sides of the two auxiliary baffles 4 are respectively connected to the main baffle 4, the front side plate 11 of the sand filling bucket 1, and the left / right side plates of the sand filling bucket 1; the main baffle 3 is square, and its upper end is connected to the middle part of the rear side plate 11 of the sand filling bucket 1, and the other end is connected to the end of the bottom plate 12 of the sand filling bucket 1.

[0027] In this embodiment, the limit baffle 2 is integrally formed by bending and is L-shaped, including a transverse limit plate 21 and a longitudinal slide 22; a first limit block 5 and two second limit blocks 6 located on both sides of the sand outlet 101 are provided on the front side plate 11 of the sand filling bucket 1; the first limit block 5 is located above the transverse limit plate 21, and is used to limit the moving position of the limit baffle 2; a slide groove is formed between the second limit block 6 and the side plate 11, and is used for the longitudinal slide 22 to slide; the ratio between the distance D between the transverse limit plate 21 and the first limit block 5 and the height H of the limit baffle 2 is 4:5. In the initial state, the longitudinal slide 22 is inserted into the slide groove to block the sand outlet 101; when sand filling operation is required, the operator uses a hammer to knock the transverse limit plate 21 to move the limit baffle 2 upward until the transverse limit plate 21 hits the first limit block 5 above. At this time, the sand filling port 101 is opened, and the sand will slide down under the action of gravity; the lower 1 / 5 of the longitudinal slide 22 is still in the slide groove. Since the sand will generate thrust on the longitudinal slide 22 when it flows out, it is ensured that the limit baffle 2 will not fall off.

[0028] In this embodiment, the bottom of the sand filling bucket 1 is provided with a foot 7, which is used to suspend the bottom of the sand filling bucket 1 when the sand filling bucket 1 is placed on the transformer oil tank cover, thereby avoiding interference between the sand filling bucket 1 and some parts on the oil tank cover. Further, the foot 7 includes two spaced channel steels.

[0029] In this embodiment, the first limit block 5 is a short channel steel; the first limit block 5, the second limit block 6 and the foot 7 are respectively welded and fixed to the sand filling bucket 1. At this time, the connection reliability is high, the rigidity is large, and the integrity is good, so that during the sand filling process, the limit block and the foot will not loosen, and the safety factor is high.

[0030] In this embodiment, the upper ends of the left and right side plates 11 of the sand filling bucket 1 are respectively provided with a group of spaced hanging holes 103. During the sand filling operation, the hanging rope can be loaded into the hanging hole 103, and then the sand filling bucket 1 can be lifted and moved by a crane, which is convenient to operate.

[0031] Working principle:

[0032] When performing the sand filling operation, first use a crane to hang the sand filling bucket 1 on the transformer oil tank cover, and place a funnel (which can be a square funnel) at the opening of the reinforcing beam, with the funnel mouth located directly below the sand outlet 101; then use a hammer to knock the limit baffle 2 to move it upward to the first limit block 5, at which time the sand in the sand filling bucket 1 will slide out of the sand outlet 101 through gravity and fall into the funnel, and then flow into the reinforcing beam that needs to be filled with sand; after the sand filling is completed, move the limit baffle 2 to its original position to prevent the sand from continuing to slide.

[0033] It should be pointed out that the sand filling tool of the present application is not only suitable for sand filling of transformer oil tank reinforcement beams, but can also be used in other working environments that require sand filling.

[0034] The above general description of the utility model involved in this application and the description of its specific implementation method should not be understood as limiting the technical solution of the utility model. Based on the disclosure of this application, those skilled in the art can add, reduce or combine the disclosed technical features in the above general description or / and the specific implementation method (including examples) without violating the constituent elements of the utility model involved, to form other technical solutions within the scope of protection of this application.
