Description

[0002] A silo is a warehouse for storing bulk materials, which is widely used in industry and agriculture. The cross-sectional shape of the silo can be rectangular, polygonal or circular. During the storage process of the silo, pre-stress needs to be applied to the outer wall when the silo is established, and pre-pressure needs to be applied to the outside of the silo according to the density, volume and total weight of the materials. However, for a rectangular silo, the resultant force of the pressure exerted by the materials on the four side walls will increase the stress on the corners of the silo. The pre-pressure supporting devices in the prior art are mostly used for circular silos, and their structure is not suitable for rectangular silos. Even if pre-pressure is applied to the outer surface of a rectangular silo, the existing pre-pressure supporting devices cannot ensure that the same amount of pre-pressure is applied to the adjacent side walls of the rectangular silo at the same time.

[0063] In addition, the technical features involved in the different embodiments of the application described below can be combined with each other as long as there is no conflict.

[0064] In combination Figures 1-7 As shown, the rectangular silo support device provided by the embodiment comprises:

[0065] The first pressing assembly 1 is adapted to apply a first pre-tightening force to the first side wall of the rectangular silo in the working state;

[0066] The second pressing assembly 2 is adapted to apply a second pre-tightening force to the second side wall adjacent to the first side wall in the working state;

[0067] The adjusting assembly 6 is connected with the first pressing assembly 1 and the second pressing assembly 2 at the same time, and is adapted to synchronously adjust the pre-tightening force of the first pressing assembly 1 and the second pressing assembly 2 to the rectangular silo;

[0068] Among them, the first pre-tightening force and the second pre-tightening force are equal in size and perpendicular in direction.

[0069] Preferably, the rectangular silo support device provided by the embodiment is mainly applied to a rectangular silo structure and is preferably supported on the outer wall side wall of the rectangular silo. The outer wall side wall of the rectangular silo can include four wall surfaces, wherein the rectangular silo support device can simultaneously support two side walls of the rectangular silo, i.e., a first side wall and a second side wall, wherein the first side wall and the second side wall are adjacently arranged, and further, four rectangular silo support devices can be arranged around one rectangular silo to simultaneously support the side walls of the rectangular silo; as a deformation, two rectangular silo support devices can be arranged around one rectangular silo, and the two rectangular silo support devices are oppositely arranged, so as to also ensure that the four side walls of the rectangular silo are simultaneously supported.

[0070] Preferably, the first pressing assembly 1 and the second pressing assembly 2 are configured in the same structure, and an acting force is applied to the rectangular silo by contacting the outer wall of the rectangular silo, and further, the first pressing assembly 1 and the second pressing assembly 2 are arranged at the same height position of the outer wall of the rectangular silo in the longitudinal direction.

[0071] Preferably, the adjusting assembly 6 is directly or indirectly connected with the first pressing assembly 1 and the second pressing assembly 2, and in the working state, the first pressing assembly 1 and the second pressing assembly 2 are simultaneously subjected to an acting force, so as to adjust the pre-tightening force of the first pressing assembly 1 and the second pressing assembly 2 on the rectangular silo.

[0072] As an implementation form, the adjusting assembly 6 can simultaneously apply an acting force perpendicular to the first side wall and the second side wall of the rectangular silo to the first pressing assembly 1 and the second pressing assembly 2; as another implementation form, the adjusting assembly 6 can also simultaneously apply a rotating force to the first pressing assembly 1 and the second pressing assembly 2, so that the first pressing assembly 1 and the second pressing assembly 2 are more closely attached to the first side wall and the second side wall and form a pressing relationship, thereby achieving a pre-tightening effect. The rectangular silo support device provided by the present application synchronously adjusts the first pressing assembly 1 and the second pressing assembly 2 by arranging the adjusting assembly 6, applies pre-tightening forces of equal size and opposite directions to the first side wall and the adjacent second side wall of the rectangular silo, so as to simultaneously apply the same pre-tightening force to the adjacent side walls of the rectangular silo, avoid deformation of the silo corners caused by the pressure of the material in the silo on the wall, and even avoid damage and leakage of the silo.

[0073] By ensuring that the pre-pressure moments of the first side wall and the adjacent second side wall are of the same size, uneven stress on the adjacent two side walls is avoided. Since the material inside the rectangular silo is in a natural state of scattering during the falling process, the force of the material on each side wall tends to be approximately the same. Therefore, the supporting device for the rectangular silo provided in the embodiment can better protect the side walls of the rectangular silo by ensuring that the stress on the adjacent two side walls is balanced, thereby avoiding the situation where each supporting device independently acts to exert different sizes of force on different side walls.

[0104] Preferably, the handle 633 serves as the force applying part of the force applying unit, and the external force is applied to the handle 633, which rotates around the screw rod axis, thereby driving the screw rod to rotate around the screw rod axis, and further driving the two moving blocks 635 to move synchronously.

[0105] Preferably, the handle 633 can be in the shape of a disc or a crank, and the external force is applied to the edge of the disc or the end of the crank away from the screw rod axis, which can extend the distance of the force to the rotation axis, thereby changing the length of the moment of force, so that the rotation of the screw rod is more labor-saving.

[0106] As a deformation, the handle 633 is not arranged, and the end of the first screw rod 631 away from the second screw rod 632 is directly connected to an external motor, which drives the screw rod to rotate through the motor.
