Description

Technical Field

[0001] The utility model relates to the technical field of cement clinker warehouse grids, in particular to a grid support. Background Art

[0002] Cement clinker is a semi-finished product of cement. It is a block-like substance formed by high-temperature burning of raw materials such as limestone and clay. Cement clinker is mixed with some additives in a certain proportion and then ground into cement.

[0003] As an important storage facility in the cement production process, the cement clinker silo is designed to store cement clinker efficiently and safely to prevent external environmental factors from affecting its quality. The silo consists of two parts: one is the silo structure constructed of cement materials, which is used to directly store cement clinker; the other is the steel structure roof house located above the silo, whose main function is to protect the silo from external bad weather (such as rain and snow), prevent the clinker from getting damp or contaminated, and ensure the quality of the cement clinker.

[0004] When building a cement clinker silo, the silo at the bottom adopts a grid structure as the main body. The grid is a structure in which multiple rods are arranged according to a certain pattern and connected through nodes. It is easy to install and economical in materials. The grid has good seismic performance and can withstand the effects of natural forces such as wind loads, snow loads and earthquakes, ensuring the overall strength of the cement clinker silo.

[0005] The nodes of the grid are where the rods meet. They are responsible for collecting and redistributing the forces in various directions to ensure the overall stability and bearing capacity of the grid. The nodes usually use sliding bearings composed of an upper seat plate, a lower seat plate and a spherical cap lining plate located between the upper seat plate and the lower seat plate. The upper seat plate can slide relative to the spherical cap lining plate. The rods of the grid are welded above the upper seat plate. When external forces act on the grid, the upper seat plate and the spherical cap lining plate slide relative to each other, thereby absorbing and dispersing stress and resisting earthquakes, thereby increasing the service life of the grid. The prior art "A high-strength spherical bearing" (publication number: CN204875503U) discloses a spherical bearing in a grid structure engineering, but the prior art still has the following technical problems:

[0006] Since the contact surface between the upper seat plate and the spherical crown lining of the sliding bearing needs to slide relative to each other in order to disperse the stress, thereby avoiding stress concentration and damage to the truss nodes, when the sliding bearing of the prior art is installed, due to the high dust content in the surrounding environment, dust particles are easily embedded in the contact surface between the upper seat plate and the spherical crown lining, thereby increasing the friction coefficient, resulting in increased resistance of the sliding bearing when moving, affecting the sliding effect, and reducing the ability of the sliding bearing to disperse the load. The hard particles in the dust will wear the sliding surface material like abrasives, accelerate its loss, and shorten the service life of the sliding bearing; if too much dust accumulates, it will also cause the sliding bearing to get stuck and unable to slide freely, making the sliding function of the sliding bearing invalid; seriously reducing the seismic resistance of the sliding bearing, making it easy for the truss to collapse when it is loaded. Utility Model Content

[0007] The utility model provides a grid support, which can solve the problem that dust particles are easily embedded in the sliding surface of the sliding support in the prior art, thereby causing the sliding support to lose its sliding ability, reducing the anti-seismic ability of the sliding support, and causing the grid to easily collapse when loaded.

[0008] The present application provides the following technical solutions: a grid support, comprising a lower seat plate, an upper seat plate located above the lower seat plate, a stainless steel plate fixed to the bottom of the upper seat plate, and a spherical cap lining plate located between the stainless steel plate and the lower seat plate, wherein the spherical cap lining plate is square in shape around and has a spherical bottom surface, a groove is provided at the bottom of the upper seat plate, the stainless steel plate is fixed in the groove, and the groove covers the entire lower seat plate and the spherical cap lining plate;

[0009] A square enclosure is also fixed above the lower seat plate, the stainless steel plate is pressed tightly on the upper end surface of the square enclosure, and the ball crown lining plate is located in a square space surrounded by the square enclosure;

[0010] It also includes an ash blocking mechanism, which includes a baffle slidably connected to the inner wall of the groove of the upper seat plate; a rectangular groove is provided on the inner wall of the groove of the upper seat plate, and the baffle can slide horizontally in the rectangular groove, a sliding column is fixed in the rectangular groove, a compression spring is sleeved on the sliding column, and a sliding hole corresponding to the sliding column is provided on the baffle, one end of the baffle extending into the rectangular groove is sleeved on the sliding column and is compressed by the compression spring, and the end of the baffle away from the sliding column is pressed against the wall surface of the lower seat plate.

[0011] Beneficial effects:

[0012] 1. Improve sliding efficiency: The compression force of the compression spring can keep the baffle in a state of sealing the notch of the groove when the upper seat plate slides relative to the lower seat plate, which can prevent large particles of dust and impurities from entering the groove and prevent dust from being embedded in the sliding contact surface between the stainless steel plate and the ball crown lining plate. At the same time, the square enclosure surrounds the ball crown lining plate, and the stainless steel plate also presses the upper surface of the square enclosure, so that the spatial area where the ball crown lining plate and the stainless steel plate are in sliding contact is closed, further strengthening the sealing of the sliding contact surface between the stainless steel plate and the ball crown lining plate. Even if some small particles of dust enter the groove of the upper seat plate, they will be blocked by the square enclosure to prevent small particles of dust from adhering to the sliding contact surface between the stainless steel plate and the ball crown lining plate, maintaining the low friction characteristics of the sliding contact surface, avoiding the sliding jam between the upper seat plate and the lower seat plate, and improving the sliding efficiency.

[0013] 2. Extend service life: The baffle reduces the wear of dust particles on the sliding contact surface of the stainless steel plate and the ball crown lining, extends the service life of the stainless steel plate and the ball crown lining, and reduces maintenance costs and replacement frequency.

[0014] Furthermore, a square groove is provided on the top of the spherical crown lining plate, a square plate is fixed in the square groove, the square plate is made of polytetrafluoroethylene, and the stainless steel plate is pressed against the square plate.

[0015] Beneficial effects: The material of the square plate is polytetrafluoroethylene, which has a smooth surface and can maintain low friction characteristics without the need for additional lubricants, which is beneficial to improving the sliding efficiency of the contact surface between the stainless steel plate and the square plate. At the same time, the polytetrafluoroethylene material can maintain performance stability at high temperatures and can be used in various environments, improving applicability.

[0016] Furthermore, a spherical groove is provided above the lower seat plate, a spherical face plate is fixed in the spherical groove, the spherical face plate is made of polytetrafluoroethylene, and the bottom surface of the spherical crown lining plate is pressed tightly into the concave surface of the spherical face plate.

[0017] Beneficial effects: The material of the ball panel is polytetrafluoroethylene, which improves the smoothness of the contact surface between the ball crown lining and the ball panel and improves the sliding efficiency. At the same time, the shape of the spherical surface can evenly transfer the load distributed on the lower seat plate, reduce local stress concentration, and protect the connection structure of the entire support from damage.

[0018] Furthermore, it also includes a support seat, which includes a bottom plate fixed above the upper seat plate and a plurality of rib plates fixed above the bottom plate, and the plurality of rib plates are fixed on the bottom plate in a criss-cross shape.

[0019] Beneficial effect: The rib plate is fixed on the bottom plate in a crisscross shape, which improves the lateral and longitudinal load bearing capacity of the support seat, strengthens the strength of the entire support seat, and ensures the supporting stability of the support seat.

[0020] Furthermore, it also includes a support ball fixed on the rib plate, and the support ball is provided with a plurality of threaded holes for connecting the grid rods.

[0021] Beneficial effect: Since the number of rods in the grid is large and in different directions, the use of spherical bearing balls can facilitate the connection of the rods with the bearing balls from multiple different directions, thereby improving the convenience of installation of the entire sliding bearing and the rods.

At the same time, polytetrafluoroethylene also has self-lubricating properties, so that the stainless steel plate 11 and the square enclosure 4 can slide smoothly, reducing the sliding jam.

[0033] A spherical groove is provided above the lower seat plate 1, in which a spherical panel 2 is fixed, the spherical panel 2 is made of polytetrafluoroethylene, and the bottom surface of the spherical crown lining plate 3 is a spherical surface, so that the bottom surface of the spherical crown lining plate 3 can be pressed tightly into the recessed surface of the spherical panel 2 and the two can slide.

[0034] The bottom of the upper seat plate 5 is provided with a groove, which covers the entire lower seat plate 1 and the ball crown lining plate 3. Figure 1 As shown, the width of the groove is slightly larger than the width of the lower seat plate 1. Figure 2 As shown, the length of the groove is greater than that of the lower seat plate 1, so that there is a certain sliding distance between the upper seat plate 5 and the lower seat plate 1; the stainless steel plate 11 is fixed in the groove, and the stainless steel plate 11 is pressed on the top of the square plate and can slide relative to the square plate.

[0035] Dust blocking mechanism Figure 2 , Figure 3 and Figure 4 As shown, it includes a baffle 12 slidably connected to the inner walls of the groove on both sides of the upper seat plate 5; a rectangular groove 16 is provided on the inner wall of the groove of the upper seat plate 5, as shown in FIG. Figure 4 As shown ( Figure 4 for Figure 2 Bottom view after BB section), one end of the baffle 12 extends into the rectangular groove 16 and can slide horizontally in the rectangular groove 16, a slide post 14 is fixed in the rectangular groove 16, a compression spring 15 is sleeved on the slide post 14, and a sliding hole 13 corresponding to the slide post 14 is provided on the baffle 12, one end of the baffle 12 extending into the rectangular groove 16 is sleeved on the slide post 14 and is tightened by the compression spring 15, the end of the baffle away from the slide post is an arc surface, and the arc surface is tightly pressed against the wall surface of the lower seat plate 1, when the entire upper seat plate 5 slides horizontally relative to the spherical crown lining plate 3, the baffle 12 can always maintain the sealing effect on the groove of the lower seat plate 1, thereby preventing large particles of dust from embedding in the sliding contact surface between the stainless steel plate 11 and the spherical crown lining plate 3.

[0036] The support seat includes a bottom plate 6 fixed on the upper seat plate 5 and a plurality of ribs fixed on the bottom plate 6, the ribs including two longitudinal reinforcing ribs 7 and two transverse reinforcing ribs 8, and the four reinforcing ribs are fixed on the bottom plate 6 in a crisscross pattern. The support ball 10 is fixed on the longitudinal reinforcing ribs 7 and the transverse reinforcing ribs 8, and the support ball 10 is also provided with a plurality of threaded holes for connecting the grid rods 9.

[0037] The use principle of this support is as follows:

[0038] When the grid is installed, the lower seat plate 1 is fixed on the ground, and Figure 2 The length direction of the groove at the bottom of the middle upper seat plate 5 is arranged along the radial direction of the grid. When the grid is subjected to load, the stress will be dispersed to the support balls 10 on each sliding support through the rod 9. After the support balls 10 are subjected to force, the upper seat plate 5 will slide relatively on the square plate and the square enclosure 4 to disperse the stress load and improve the seismic resistance. During the relative sliding process between the upper seat plate 5 and the lower seat plate 1, the baffle will be pushed by the outer wall of the lower seat plate 1 and slide in the rectangular groove on the inner wall of the groove of the upper seat plate 5.

A slot is opened on the outer wall of the square enclosure 4, and one end of the connecting plate 18 can be inserted into the slot.

[0041] The advantage of this solution is that when installing this structure, the two baffles 12 on the upper seat plate 5 are pushed to both sides, and then the upper seat plate 5 is buckled onto the lower seat plate 1. After loosening the two baffles 12, the connecting plate 18 relies on the rebound force of the compression spring 15 to snap into the slot of the square enclosure 4 to improve the sealing performance.

[0042] Embodiment 3

[0043] The difference between this embodiment and the second embodiment is that Figure 5 An L-shaped connecting plate 18 is fixed above the end of the baffle 12, and the end of the baffle 12 contacts the side wall of the lower seat plate 1, thereby achieving a double sealing effect and further improving the sealing performance.
