[0024] The embodiments of the utility model will be described in detail below in combination with the drawings, but the utility model can be implemented in various different ways as defined and covered below.

[0025] Please refer to Figures 1-3 The utility model provides a technical scheme: a storage bin internal construction device, including base 1, the central column 2 of rotation setting in base 1, the rotation drive mechanism 3 for driving central column 2 autogyration, the operation platform of synchronous rotation of being equipped with central column 2 with central column 2 and the lifting mechanism 4 for controlling operation platform height, operation platform includes fixed platform 51 and at least one dynamic platform 52, fixed platform 51 slides along vertical sliding and is arranged on central column 2, and the sliding direction between dynamic platform 52 and vertical direction has included angle, and dynamic platform 52 is slidably arranged on fixed platform 51, so that dynamic platform 52 can slide close or away from the inner wall of storage bin.

[0027] Fixed platform 51 is provided with at least one dynamic platform 52, when fixed platform 51 is provided with multiple dynamic platforms 52, multiple branches can be separated from fixed platform 51, multiple branches are respectively towards different directions, and multiple dynamic platforms 52 are respectively installed on different branches.

[0028] Embodiment 1

[0029] When using this device to construct inside a rectangular storage silo, since the vertical projection of the storage silo is rectangular, the distance between the moving platform 52 and the inner wall of the storage silo will change when the central column 2 rotates and drives the working platform to rotate. At this time, it is necessary to adjust the position of the moving platform 52 on the fixed platform 51 according to the distance change so that the distance between the moving platform 52 and the inner wall of the storage silo is kept within the range of safe operation for the workers, thereby ensuring that the workers can carry out comprehensive construction on the inner wall of the storage silo and ensure the safety of the operation.

[0030] Example 2

[0031] like Figure 1 As shown, when using this device to construct the inner top wall of the storage bin, since the inner top wall of the storage bin is conical, the distance between the moving platform 52 and the inner wall of the storage bin will shorten when the working platform rises. In order to prevent the moving platform 52 from interfering with the inner top wall of the storage bin, the moving platform 52 needs to be moved towards the central column 2 when the working platform rises, so that the working platform can rise smoothly and thus realize the construction of the inner top wall of the storage bin.

[0032] This device divides the construction platform into a fixed platform 51 and a movable platform 52. The movable platform 52 can slide on the fixed platform 51 to move closer to or further away from the inner wall of the storage bin. During the lifting or rotation of the work platform, the position of the movable platform 52 on the fixed platform 51 can be adjusted according to the distance between different construction positions on the inner wall of the storage bin and the central column 2. This allows construction personnel to carry out comprehensive construction on the inner wall of the storage bin on the movable platform 52. It can adapt to storage bins of different shapes and has stronger applicability. Furthermore, the movable platform 52 can be moved to carry out construction on the inner top wall of the storage bin, making construction on the inner top wall of the storage bin simpler. At the same time, during construction, the distance between the movable platform 52 and the inner wall of the storage bin can be kept within the safe operating range for the workers, ensuring construction safety.

[0033] like Figure 1 As shown, in some examples, a distance sensor 6 is provided on the moving platform 52 for measuring the distance between the moving platform 52 and the inner wall of the storage bin;

[0034] When the position of the working platform changes, causing a change in the distance between the moving platform 52 and the inner wall of the storage bin, the operator can only judge the distance between the moving platform 52 and the inner wall of the storage bin by visual inspection. Therefore, it is impossible to determine the accurate distance between the moving platform 52 and the inner wall of the storage bin. When adjusting the position of the moving platform 52, it may not be possible to adjust it quickly and accurately. However, after installing a distance sensor 6 on the moving platform 52, the precise distance between the moving platform 52 and the inner wall of the storage bin can be measured by the distance sensor 6. Based on the measurement structure of the distance sensor 6, the position of the moving platform 52 on the fixed platform 51 can be precisely adjusted, which improves the adjustment accuracy and reduces the adjustment time.

[0035] Furthermore, at least two distance sensors 6 are provided on the moving platform 52. The two distance sensors 6 are arranged on both sides of the moving platform 52 in the width direction, and are used to measure the distance between the end face of the moving platform 52 away from the central column 2 and the inner wall of the storage compartment in the width direction.

[0036] Currently, storage bins are generally circular, rectangular, or polygonal in shape. Therefore, the inner walls of storage bins are usually concave or flat. At the same time, the moving platform 52 has a certain width, such as 2m, to facilitate the standing and working of operators. This means that the end of the moving platform 52 away from the central column 2 is closest to the inner wall of the storage bin at one of the corners on either side of the width direction of the moving platform 52. Only when the end face of the moving platform 52 away from the central column 2 is exactly parallel to the inner wall of the storage bin, the distance from different positions of the end of the moving platform 52 away from the central column 2 to the inner wall of the storage bin is equal. Therefore, by distributing two distance sensors 6 on both sides of the width direction of the moving platform 52, the distance between the end face of the moving platform 52 away from the central column 2 and the inner wall of the storage bin on both sides of the width direction can be measured to prevent the moving platform 52 from contacting and colliding with the inner wall of the storage bin, thus ensuring the safety of the moving platform 52 when it moves.

[0037] In some examples, a thruster 7 is provided on the stationary platform 51 for driving the moving platform 52 to move on the stationary platform 51;

[0038] The moving platform 52 is moved on the fixed platform 51 by the thruster 7, which makes it more convenient to move the moving platform 52. At the same time, with the distance sensor 6 set on the moving platform 52, the moving distance of the moving platform 52 can be precisely controlled, making the moving platform 52 faster and more accurate.

[0039] Specifically, the thruster 7 is a conventional technology in this field, such as using a hydraulic cylinder, a pneumatic cylinder, or driving the moving platform 52 to move by rotating a lead screw driven by a motor.

[0040] Furthermore, multiple working platforms are provided on the central column 2. The multiple working platforms are equally spaced around the central column 2 along the rotation axis of the central column 2, or the multiple working platforms are symmetrically arranged in pairs on the central column 2 about the rotation axis of the central column 2.

[0041] like Figure 1 As shown, two working platforms are installed on the central column 2. The two working platforms are symmetrically arranged on both sides of the central column 2 about the rotation axis of the central column 2. The two working platforms generate torques on both sides of the central column 2. The two torques are balanced with each other, which increases the stability of the central column 2. At the same time, it can also increase the working positions of the workers, and can carry out construction on multiple positions on the inner wall of the storage silo at the same time, thus improving construction efficiency.

[0042] When three work platforms are arranged on the center column 2, the three work platforms can be installed at equal intervals along the circumferential direction of the rotation axis of the center column 2, so that the moment balance can be achieved, and the positions available for the workers to work can be further increased, and the construction efficiency can be further improved.

[0043] Specifically, as shown in Figure 2 The work platform further comprises a center cylinder 8, the center cylinder 8 is arranged on the center column 2 in a sliding manner along the vertical direction, and the fixed platform 51 is fixedly arranged on the center cylinder 8, and the center cylinder 8 is fixedly provided with a cable 81 for connecting the end of the fixed platform 51 away from the center cylinder 8;

[0044] All the work platforms on the center column 2 are integrated on the center cylinder 8, so that the common lifting of the multiple work platforms can be realized, and it is ensured that the multiple work platforms can always be kept at the same height, so that the roll moment generated between the multiple work platforms can be balanced to the maximum extent. Meanwhile, the cable 81 is fixedly arranged on the center cylinder 8, and the other end of the cable 81 is connected to the end of the fixed platform 51 away from the center cylinder 8, so that the weight of the fixed platform 51 and various loads borne by the fixed platform 51 are shared to the center cylinder 8, and the stability of the fixed platform 51 is improved.

[0045] Specifically, the top end of the center column 2 is fixedly provided with a rotating table 21, which is arranged in a rotating manner in a ventilation hole opened at the top end of the storage bin, or is arranged in a rotating manner in a rotating seat 22 prearranged on the inner top wall of the storage bin;

[0046] As shown in Figure 1 For some storage bins with ventilation holes opened at the top, the rotating table 21 at the top end of the center column 2 can be rotatably matched into the ventilation hole opened at the top of the storage bin, so as to increase the overturning resistance of the center column 2 and improve the safety of the construction device. When the top of the storage bin is not provided with a ventilation hole, as shown in Figure 3 a rotating seat 22 is fixedly arranged on the inner top wall of the storage bin, and then the rotating table 21 is arranged in a rotating manner in the hole of the rotating seat 22, so as to increase the overturning resistance of the center column 2 and improve the safety of the construction device.

[0047] Further, the rotating table 21 is provided with a mounting platform 23, and the lifting mechanism 4 is arranged on the mounting platform 23 and is used to rotate synchronously with the center column 2;

[0048] When the rotating driving mechanism 3 drives the center column 2 to rotate, the rotating table 21 and the center column 2 rotate synchronously, and the lifting mechanism 4 arranged on the mounting platform 23 also rotates synchronously with the center column 2, so that the height adjustment of the work platform can be realized while the center column 2 rotates.

[0049] Specifically, in some examples, the internal construction device of the storage silo also includes a rotating support 9, which is mounted on the base 1 or used to be erected at the bottom of the storage silo, and the central column 2 is rotatably mounted inside the rotating support 9.

[0050] Specifically, the central column 2 includes several assembly sections that are sequentially spliced ​​along the height direction, so that the height of the central column 2 can be adjusted according to the height of the storage bin;

[0051] The height of the central column 2 is adjusted according to the internal height of the storage silo to be constructed, thereby increasing the applicability of the construction device.

[0052] like Figure 1 As shown, the rotary drive mechanism 3 is mounted on the base 1, and a reduction mechanism is installed inside the base 1. The rotary drive mechanism 3 outputs torque to the reduction mechanism, which then drives the central column 2 to rotate.

[0053] Specifically, the lifting mechanism 4 is a conventional technical means in this field, such as using a winch;

[0054] Specifically, the sliding engagement between the moving platform 52 and the fixed platform 51 is a conventional technical means in this field, such as setting a slide rail on the fixed platform 51 and sliding the moving platform 52 in the slide rail.
