Description

Technical Field

[0001] This utility model relates to the field of storage tank bottom belt chain technology, and in particular to a storage tank bottom belt chain support guide rail structure. Background Technology

[0002] In tobacco processing, due to the different sources of raw materials, various indicators vary greatly. Therefore, starting from the moment the tobacco leaves enter the warehouse, different production areas and grades are blended into a single batch – a formulation. This is mainly achieved through large-scale mixing in storage tanks, which greatly simplifies and integrates raw materials from different production areas, grades, and with complex and diverse internal qualities, forming standardized units and ensuring the internal quality stability of the large formulation during application.

[0003] In the silk-making workshop, storage tanks typically face challenges such as long conveying distances, heavy loads, and harsh environmental conditions (mainly high temperatures, high tides, and dust), posing significant challenges to the stability and reliability of the equipment.

[0004] In the existing technology, the bottom belt of the storage tank is usually supported by a chain of channel steel. However, the longitudinal support frame of the storage tank has a large span. Sometimes, due to the needs of the production process, the local load on the bottom belt of the storage tank increases and the load on both sides is uneven during operation, which causes the support bars used to support the bottom belt of the storage tank to deform. At the same time, it is also easy to cause the bottom belt to deviate or get stuck. Utility Model Content

[0005] In view of this, the purpose of this utility model is to provide a storage tank bottom belt chain support guide rail structure to solve the problems in the prior art where the local load on the storage tank bottom belt increases and the load on both sides is uneven during operation, which causes the support bar used to support the storage tank bottom belt to deform, and at the same time, it is easy to cause the bottom belt to run off track and get stuck.

[0006] This utility model solves the above-mentioned technical problems through the following technical means: a storage tank bottom belt chain support guide rail structure, including a support bar for supporting the storage tank bottom belt and a chain guide rail for supporting the bottom belt chain. The upper surface of the support bar is fixedly connected to the lower surface of the storage tank bottom belt, and both ends of the support bar are fixedly connected to the storage tank bottom belt chains on both sides. The support bars are arranged parallel at intervals along the running direction of the storage tank bottom belt. It also includes a roller guide rail. Both the chain guide rail and the roller guide rail are fixedly connected to the support of the storage tank. Adjacent support bars are hinged with mutually aligned cross braces. The bottom of the cross brace is provided with a roller. The lower end of the roller abuts against the roller guide rail. The roller rolls or slides on the roller guide rail as the cross brace moves.

[0007] Optionally, the roller has a spherical roller body, and the roller guide rail has a concave arc-shaped guide rail groove. When the roller has a spherical roller body and the roller guide rail has a concave arc-shaped guide rail groove, the spherical roller always tends to return to the lowest point of the concave arc-shaped guide rail groove, thereby driving the support bar connected to the cross brace to return to its correct position, thus achieving an automatic correction function for the bottom strip of the storage tank. At the same time, the added roller and guide rail can also reduce the probability of deformation of the support bar due to load changes.

[0008] Optionally, the chain guide rail is L-shaped and symmetrically arranged on both sides along the running direction of the storage tank bottom belt. By setting the L-shaped chain guide rail, a maximum offset is set for the storage tank bottom belt, allowing the storage tank bottom belt to have room for self-adjustment and avoiding serious jamming.

[0009] Optionally, a guide wheel is fixed on the chain guide rail on the outer side of the bottom belt chain to prevent the bottom belt chain from running off-track. The guide wheel is used to correct the bottom belt chain and prevent the chain from getting stuck due to direct friction with the side of the guide rail.

[0010] Optionally, the initial distance between the bottom belt chain and the guide wheel is 5-10 mm, providing a margin for the operation of the bottom belt chain.

[0011] Optionally, the roller is detachably connected to the cross brace via fasteners. This allows for easy replacement of the roller in case of failure, saving time.

[0012] Optionally, a proximity switch is provided on the chain guide rail on the outer side of the bottom chain. The proximity switch is used for alarm purposes.

[0013] The beneficial effects of this utility model are:

[0014] 1. This utility model enhances the stability of the entire storage tank bottom belt by installing cross braces between adjacent support bars, mounting rollers on these cross braces, and adding corresponding roller guide rails. This results in a more rational support layout. The cross braces, hinged at both ends, provide additional support to adjacent support bars in horizontal sections. Furthermore, the cross braces can rotate relative to the support bars during turns, thus not affecting chain transmission. Additionally, the rollers can rotate relative to the roller guide rails, reducing friction and extending the service life of the guide rails. With the addition of cross braces, rollers, and corresponding guide rails, the strength and fault tolerance of the entire supporting guide rail structure increase in response to changes and increases in the load on the storage tank bottom belt.

[0015] 2. This utility model also effectively addresses and prevents the deviation of the storage tank bottom belt by setting up an L-shaped chain guide rail, a guide wheel that plays an anti-deviation role, and a proximity switch. In particular, when using rollers with spherical roller bodies and roller guide rails with concave arc-shaped guide rail grooves, the spherical rollers always tend to return to the lowest point of the concave arc-shaped guide rail groove, thereby driving the support bar connected to the cross brace to return to the correct position, thus playing an automatic deviation correction role for the storage tank bottom belt, thereby avoiding the jamming phenomenon caused by excessive deviation of the storage tank bottom belt, and ultimately improving production efficiency.

Therefore, the terms used to describe the positional relationship in the figure are only for illustrative purposes and should not be construed as limiting this utility model. For those skilled in the art, the specific meaning of the above-mentioned terms can be understood according to the specific circumstances.

[0025] like Figures 1-6 As shown, this utility model provides a storage tank bottom belt chain support guide rail structure, which includes a support bar 11 for supporting the storage tank bottom belt and a chain guide rail 13 for supporting the bottom belt chain 12. The upper surface of the support bar 11 is fixedly connected to the lower surface of the storage tank bottom belt, and both ends of the support bar 11 are fixedly connected to the storage tank bottom belt chains on both sides. The support bars 11 are arranged parallel to each other at intervals along the running direction of the storage tank bottom belt.

[0026] In this embodiment, the supporting guide rail structure also includes a roller guide rail 14. Both the chain guide rail 13 and the roller guide rail 14 are fixedly connected to the support of the storage tank. Adjacent support bars 11 are hinged with mutually aligned cross braces 111, and the bottom surface of the cross braces 111 is flush with the bottom surface of the support bars 11. Specifically, a pin seat is welded to the bottom side of the support bar 11, and the cross brace 111 is hinged to the support bar 11 by rotating the pin.

[0027] In this embodiment, the bottom of the cross brace 111 is provided with a roller 112. The lower end of the roller 112 abuts against the roller guide rail 14. The roller 112 rolls or slides on the roller guide rail 14 as the cross brace 111 moves. Under normal circumstances, the roller 112 rolls on the roller guide rail 14. However, in extreme cases, the roller 112 may get stuck but can still slide on the roller guide rail 14. When sliding occurs, it will make a loud noise, reminding the on-site inspection personnel to take action.

[0028] In this embodiment, the horizontal brace 111, which is hinged at both ends, provides additional support to the adjacent support bar 11 in the horizontal section. The roller 112 provides additional support to the horizontal brace 111. At the same time, when the bottom belt chain 12 rotates around the drive gear, the horizontal brace 111 can rotate with the hinge pin, without affecting the transmission of the bottom belt chain 12.

[0029] In this embodiment, to prevent the bottom belt chain 12 from running off-center, the chain guide rail 13 is L-shaped and symmetrically arranged on both sides along the running direction of the bottom belt of the storage tank. A guide wheel 131 is fixed on the chain guide rail 13 on the outer side of the bottom belt chain 12 to prevent the bottom belt chain 12 from running off-center, and to prevent the chain from directly rubbing against the side of the guide rail and causing jamming.

[0030] In this embodiment, the initial distance between the bottom belt chain 12 and the guide wheel 131 is 5-10mm. In actual production, deviation is inevitable due to load variations and the structural characteristics of the storage tank bottom belt. Therefore, by setting an L-shaped chain guide rail 13, a maximum offset is set for the storage tank bottom belt, allowing it to self-adjust deviation and avoiding severe jamming.

[0031] In this embodiment, a proximity switch 132 is provided on the chain guide rail 13 on the outer side of the bottom belt chain 12. The proximity switch 132 is located between two guide wheels 131. The proximity switch 132 is connected to the workshop control system to detect the deviation of the bottom belt chain. When the proximity switch 132 alarms, the workshop control system automatically controls or manually adjusts the operating parameters to make the feeding equipment at the front end of the storage tank run at a low speed to avoid serious jamming failure of the bottom belt of the storage tank.

[0032] In this embodiment, the roller 112 is threadedly connected to the cross brace 111 by fasteners, which makes it easy to replace the roller when it locks up, saving maintenance time. Since the load on the bottom belt of the storage tank is usually above 2000Kg, the roller 112 can be made of solid rubber tires or metal rollers to provide a high auxiliary load-bearing capacity for the support bar 11. At the same time, it ensures that the roller 112 has a certain friction force and rolls on the roller guide rail 14 to reduce the chance of slippage.

[0033] In some other embodiments, to further enable the roller guide rail 14 to also have a self-adjusting function to cope with deviation, the roller 112 includes a support that can be threadedly connected to the cross brace. The bottom of the support has a hemispherical roller cavity, and a spherical roller body is provided inside the roller cavity. The roller body slides in conjunction with the roller cavity, and the hemispherical shape is a superior arc sphere, so that the roller body cannot be dislodged. The roller 112 with the spherical body can roll in any direction, and the roller guide rail 14 that cooperates with the roller 112 has an inwardly concave arc-shaped guide rail groove.

[0034] Under normal circumstances, the roller 112 with the spherical roller body can still roll back and forth along the extension direction of the roller guide rail 14. However, when the bottom belt of the storage tank may deviate due to changes in the bearing, on the one hand, it is necessary to overcome the climbing resistance of the roller, that is, the horizontal component of the correction direction given by the arc surface of the roller guide rail 14, so that the bottom belt of the storage tank itself is less likely to deviate. On the other hand, even if deviation occurs, the roller 112 with the spherical roller body will automatically center itself towards the center of the concave arc guide rail groove under the action of the arc surface, and automatically return to the lowest point of the concave arc guide rail groove, thereby playing an automatic correction role for the bottom belt of the storage tank.

[0035] It should be understood that the support side is provided with a grease nipple that connects to the roller cavity for adding lubricating oil to reduce the friction between the roller cavity and the roller body. At this time, the roller guide rail 14 and the roller 112 can be made of common wear-resistant cast iron materials, such as nickel hard cast iron and high chromium cast iron, which have good wear resistance, as well as a certain degree of self-lubrication and shock absorption.

[0036] The working principle of this utility model is as follows:

[0037] During operation, the bottom belt chain 12 drives the support bars 11, thereby moving the bottom belt of the storage tank above the support bars 11. During this process, the horizontal braces 111, hinged at both ends, provide additional support to the adjacent support bars 11 in the horizontal section. Simultaneously, as the bottom belt chain 12 rotates around the drive gear, the horizontal braces 111 can rotate relative to the support bars 11 without affecting the transmission of the bottom belt chain 12. The rollers 112 located at the bottom of the horizontal braces 111 roll on the roller guide rails 14, resulting in relatively low friction and effectively supporting the support bars 11, making them less prone to bending and deformation.

[0038] With the addition of cross braces 222, rollers 112, and corresponding guide rails, the strength and fault tolerance of the entire supporting guide rail structure increase in response to changes and increases in load on the bottom belt of the storage tank, thereby reducing the phenomenon of deviation and jamming caused by deformation of the support structure such as the support bar 11. In particular, when using rollers 112 with spherical roller bodies and roller guide rails 14 with concave arc-shaped guide rail grooves, the spherical rollers always tend to return to the lowest point of the concave arc-shaped guide rail grooves, which in turn drives the support bar 11 connected to the cross brace 111 to return to the correct position, thereby playing an automatic correction role for the bottom belt of the storage tank and avoiding jamming caused by excessive deviation of the bottom belt of the storage tank.

Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications and substitutions should be covered within the scope of the claims of this utility model.
