Description

Technical Field

[0001] The utility model relates to the technical field of power tower angle steel processing, in particular to an arc-shaped back-shoveling device which is convenient for transmitting the power tower angle steel. Background Art

[0002] Angle steel, commonly known as angle iron, is a long steel strip with two sides perpendicular to each other. There are equal-leg angle steel and unequal-leg angle steel. The two sides of the equal-leg angle steel are equal in width. The inner angle of the angle steel is an arc, and the outer angle is 90°. When installing the power tower, one angle steel needs to be placed inside the other angle steel, and the two angle steels need to fit tightly. Since the inner angle of the angle steel is an arc angle, it cannot fit tightly during the placement process, and the outer angle of the angle steel needs to be shoveled into an arc. When transporting the angle steel to the interior of the existing shoveling device, manual placement is usually adopted, which makes it difficult to place the angle steel, laborious and time-consuming. At the same time, the cutting knife cannot be adjusted during the shoveling, resulting in the only way to move the angle steel for shoveling. There are errors during the shoveling, and the work efficiency is low. Utility Model Content

[0023] Example 1

[0024] Embodiment 1 of the utility model is an arc-shaped back-shoveling device for facilitating the transmission of angle steels of power towers, comprising a device body 1, wherein the device body 1 is divided into a working chamber 10 and a dust removal chamber 11 by a partition 12, wherein a clamping assembly 2 and a cutting assembly 3 of an angle steel 4 are arranged in the working chamber 10, a collecting box 111 for collecting waste materials behind the shovel is arranged at the bottom of the dust removal chamber 11, two rows of rotating rollers 124 and a plurality of through holes 123 are arranged in the partition 12, and the two ends of the angle steel 4 are located above the rotating rollers 124 for transmission to the inside of the device body 1.

[0025] Reference Figure 1 to Figure 3 The device body 1 is divided by a partition 12, and the working chamber 10 is above the partition 12, which is mainly used for cutting the outer corners of the angle steel 4 and clamping the two sides of the angle steel 4. During cutting, the cutting assembly 3 moves left and right in the long end direction of the outer corner of the angle steel 4 to make the angle steel 4 in a fixed state. At the same time, the dust removal chamber 11 performs synchronous dust removal and waste work, and collects the waste generated during the cutting process in time for centralized removal. The bottom ends of the two side edges of the angle steel 4 are located on the surface of the rotating roller 124, and a thrust is applied to the angle steel 4, so that the rotating roller 124 rotates. Finally, the angle steel 4 enters the interior of the device body 1 under the rotation of the rotating roller 124, and then is fixed by the clamping assembly 2. After fixing, the outer corner of the angle steel 4 is back-shoveled. It solves the problem of the need to manually place the angle steel 4 and the need to push the angle steel 4 for cutting, which is time-consuming and labor-intensive in the prior art, and greatly improves work efficiency.

[0026] The through hole 123 provided in the partition 12 facilitates the waste materials during cutting to enter the collection box 111 , and the size of the through hole 123 is set according to actual conditions.

[0027] In some preferred embodiments, the clamping assembly 2 includes threaded sleeves 20 respectively located on both sides of the device body 1, and a threaded rod is connected inside the threaded sleeve 20. One end of the threaded rod located inside the working chamber 10 is provided with a clamping plate 23, and the other end is provided with a rotating disk 22. It also includes an electric telescopic rod 26 and an angle steel seat 25 fixedly connected to the telescopic end of the electric telescopic rod 26. The partition 12 is provided with a first through slot 120, a second through slot 121 and a third through slot 122 from left to right, and a rotating roller 124 is provided in the first through slot 120 and the third through slot 122 respectively. The telescopic part of the electric telescopic rod 26 runs through the second through slot 121, and the bottom end of the electric telescopic rod 26 is located at the bottom of the device body 1.

[0028] Reference Figure 1After the angle steel 4 is transported from the inlet of the device body 1 to the inside of the device body 1 through the rotating roller 124 in the partition 12, the electric telescopic rod 26 is driven to move, so that the top of the angle steel seat 25 connected to the top thereof contacts the inner top angle of the angle steel 4, and then the rotating disk 22 is held by hand to move the first screw 21 in the threaded sleeve 20 close to the side of the angle steel 4, so that the clamping plate 23 contacts the side plate of the angle steel 4 for fixed clamping, ensuring that displacement is avoided during the cutting process and causing errors in the shovel back. The first screw 21 is threadedly connected to the threaded sleeve 20, and the distance between the two clamping plates 23 can be adjusted according to the specifications of the angle steel 4.

[0029] At the same time, a buffer pad 24 is provided on one side of the clamping plate 23 close to the angle steel seat 25. The buffer pad 24 is made of rubber or other materials to ensure that the clamping plate 23 and the side of the angle steel 4 are prevented from rubbing against each other during the clamping process, thereby preventing the clamping plate 23 from being worn and extending the service life of the clamping plate 23. Since the inner angle of the angle steel seat 25 is an arc-shaped right angle, the electric telescopic device at the bottom can make the angle steel seat 25 rise or fall, so that it can meet the needs of scraping the back of various angle steels 4 and improve the reuse of the device.

[0030] Example 2

[0031] In this embodiment 2, the cutting assembly 3 includes a second screw 30 driven by a first motor 34, a sliding block 31 is sleeved on the outer periphery of the second screw 30, a cutting knife 36 connected to a connecting rod 32 is provided below the sliding block 31, and the cutting portion of the cutting knife 36 is arc-shaped. A first bearing 33 is provided at the top of one of the side plates of the device body 1, and the end of the second screw 30 away from the first motor 34 is located in the first bearing 33, and the second screw 30 is consistent with the long axis direction of the top end of the angle steel seat 25.

[0032] Reference Figure 1 and Figure 2 The cutting assembly 3 drives the second screw 30 to rotate in the first bearing 33 through the first motor 34, thereby driving the sliding block 31 to move left and right. The sliding block 31 causes the cutting knife 36 connected to the bottom end of the connecting rod 32 to move left and right. The cutting knife 36 moves and cuts in the long side direction of the top end of the angle steel 4. There is no need to move the angle steel 4 during the cutting process, thereby improving the cutting accuracy and reducing the error.

[0033] In some preferred embodiments, an inverted U-shaped frame 35 is provided at the bottom end of the connecting rod 32, the cutting blade 36 is located in the U-shaped frame 35, a rotating shaft 370 driven by a second motor 37 is provided in the U-shaped frame 35, the rotating shaft 370 passes through the cutting blade 36, a second bearing 38 is provided on one side of the U-shaped frame 35, and the end of the rotating shaft 370 away from the second motor 37 is located in the second bearing 38. An inverted U-shaped frame 35 is provided at the bottom end of the connecting rod 32, the cutting blade 36 is located in the U-shaped frame 35, the rotating shaft 370 passes through the cutting blade 36, and both ends thereof are respectively connected to the second motor 37 or located in the second bearing 38, the second motor 37 drives the rotating shaft 370 to rotate, so that the cutting blade 36 rotates in the U-shaped frame 35, and the back-shoveling efficiency of the diagonal steel 4 is enhanced during cutting.

[0034] It should be noted that the bottom end of the cutting blade 36 is lower than the bottom end of the U-shaped frame 35 to avoid contact between the U-shaped frame 35 and the two side edges of the angle steel 4 during the cutting process.

[0035] Example 3

[0036] In this embodiment 3, the bottom of the dust removal chamber 11 is provided with a through pipe 110, and the bottom end of the pipe 110 is provided with a collection box 111 and a fan 112 in sequence, and a detachable filter 1110 is provided in the collection box 111. Specifically, the dust removal chamber 11, the collection box 111 and the fan 112 are connected through the pipe 110. When the fan 112 is turned on, the waste generated during the cutting process is collected above the filter 1110 inside the collection box 111 through the through hole 123, the dust removal chamber 11 and the pipe 110 in sequence. The filter 1110 can prevent the waste from entering the fan 112 through the pipe 110, and at the same time, it is convenient to take the filter 1110 from the collection box 111 to remove the waste, thereby improving the waste removal efficiency and avoiding manual removal inside the device body 1 to cause dust pollution.

[0037] When the utility model is in use, the ends of the two side edges of the angle steel 4 are brought into contact with the rotating roller 124, and a thrust is applied to the other end of the angle steel 4. The angle steel 4 is transmitted to the interior of the device body 1 under the transmission action of the rotating roller 124, and then the electric telescopic rod 26 is started to adjust the position of the angle steel seat 25 to adapt to the interior of the angle steel 4. At the same time, the rotating disk 22 is manually rotated to make the clamping plates 23 respectively located on both sides of the angle steel 4, and the buffer pad 24 is in contact with the two side edges of the angle steel 4 to avoid wear on the clamping plates 23 during clamping and shortening the service life. During the back shoveling operation, the first motor 34 and the second motor 37 are driven. The first motor 34 is a sliding block 31 that moves in the second screw rod 30, so that the cutting knife 36 connected to the connecting rod 32 at the bottom thereof moves and cuts at the same time. The second motor 37 drives the cutting knife 36 to rotate in the U-shaped seat to exert a cutting effect, thereby improving the cutting efficiency and effect. At the same time, the angle steel 4 is in a fixed state during the cutting process, and the cutting accuracy is high. Dust removal is performed synchronously during the cutting process, so that waste materials are collected on the filter screen 1110 inside the collection box 111 through the through hole 123, the dust removal chamber 11 and the pipeline 110 in sequence to avoid dust.

[0038] The above is only a preferred embodiment of the utility model and does not limit the utility model in any form.
