Abstract
Description
Technical Field
[0001] This utility model relates to the field of metallurgical lime technology, and more specifically, to a double-chamber kiln feeding track. Background Technology
[0002] Currently, the track is the key channel for transporting lime raw materials in the entire feeding system of a double-chamber lime kiln.
[0003] The existing feeding track and the contact surface of the channel steel with the wheels are prone to wear and deformation, which can cause the feeding trolley to derail or even fall off. At the same time, if there are installation errors, it will have a great impact on the wheels of the trolley. The wheels may get stuck inside the channel steel when entering the site, causing the kiln to stop. In other words, frequent maintenance or damage to the track means the shutdown of the entire kiln, resulting in low production efficiency of the lime kiln. Summary of the Invention
[0004] In view of this, this utility model proposes a double-chamber kiln feeding track, which aims to solve the problem that the existing feeding track in lime kilns is prone to wear and deformation, resulting in frequent track maintenance or damage and affecting the production efficiency of lime kilns.
[0005] This utility model proposes a double-chamber kiln feeding track, which includes: a support base; a support rail disposed on the support base for bottom support and guidance of the feeding wheel; and a U-shaped limiting member disposed above the side of the support rail so that the feeding wheel can be placed in the U-shaped groove of the U-shaped limiting member to limit the upper and lower movement of the feeding wheel.
[0006] Furthermore, in the aforementioned double-chamber kiln feeding track, the support base is a horizontally arranged H-beam, with its upper and lower flange plates arranged horizontally, and the support rail is set on the top wall of the upper flange plate of the support base.
[0007] Furthermore, in the aforementioned double-chamber kiln feeding track, the width of the upper flange plate of the support seat is greater than the width of the lower flange plate of the support seat.
[0008] Furthermore, in the aforementioned double-chamber kiln feeding track, the support base is provided with a fixed pressure plate, one end of which is fixedly installed on the top wall of the support base, and the other end is pressed and fixed on the lower flange plate of the support rail, so that the support rail can be fixedly installed on the support base.
[0009] Furthermore, in the aforementioned double-chamber kiln feeding track, the fixed pressure plate and the upper flange plate of the support seat are fixed together by bolts.
[0010] Furthermore, in the aforementioned double-chamber kiln feeding track, there are multiple fixed pressure plates, which are arranged at intervals along the length of the support rail.
[0011] Furthermore, in the aforementioned double-chamber kiln feeding track, the lower flange plate of the support seat is fixedly installed on the transverse inclined bridge frame, and the U-shaped limiting member is fixedly installed on the vertical inclined bridge frame.
[0012] Furthermore, in the aforementioned double-chamber kiln feeding track, the lower flange plate of the support seat is connected to the transverse inclined bridge frame by welding, and the U-shaped limiting member is connected to the vertical inclined bridge frame by welding.
[0013] Furthermore, in the aforementioned double-chamber kiln feeding track, the supporting rail is a track steel structure.
[0014] Furthermore, in the aforementioned double-chamber kiln feeding track, the U-shaped limiting component is a limiting channel steel structure.
[0015] This utility model provides a double-chamber kiln feeding track that utilizes the concept of train tracks, applying it to a double-chamber lime kiln. Support rails are laid across the existing inclined bridge, below a U-shaped limiting component, allowing the pressure of the feeding wheels to be transmitted to the original steel frame via the support rails and support seats. The support rails support and guide the feeding wheels, while the U-shaped limiting component provides restraint. This results in higher overall track strength for the double-chamber kiln, significantly reducing the maintenance frequency of the inclined bridge and extending the service life of both the inclined bridge and the lime kiln. It prevents wear and deformation of the steel surface of the contact groove between the feeding track and the wheels, which could cause the feeding trolley to derail or even fall. It also solves the problem of feeding wheels getting stuck due to installation errors. This double-chamber kiln feeding track can extend its service life by more than 10 years, playing a crucial role in the normal production of the lime kiln. Attached Figure Description

[0017] Figure 1 A schematic diagram of the structure of the double-chamber kiln feeding track provided in an embodiment of this utility model. Detailed Implementation
[0018] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the disclosure to those skilled in the art. It should be noted that, unless otherwise specified, embodiments and features of the present invention can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0019] See Figure 1 The figure shows a schematic diagram of the structure of the double-chamber kiln feeding track provided in this embodiment of the utility model. As shown in the figure, the double-chamber kiln feeding track includes: a support base 1, a support rail 2, and a U-shaped limiting member 3.
[0020] Support rail 2 is mounted on support base 1 to provide bottom support and guidance for loading wheel 4; U-shaped limiting member 3 is mounted on the upper side of support rail 2, such as... Figure 1 As shown, the left U-shaped limiting member 3 is located above the left side of the left support rail 2, and the right U-shaped limiting member 3 is located above the right side of the right support rail 2, so that the feeding wheel 4 can be placed in the U-shaped groove 31 of the U-shaped limiting member 3 to limit the feeding wheel 4 vertically. In other words, the support seat 1, support rail 2 and U-shaped limiting member 3 in the double-chamber kiln feeding track are all arranged in pairs to support and limit the left and right feeding wheels 4.
[0021] Specifically, a support seat 1 is installed on the existing inclined bridge, especially on the transverse inclined bridge frame 5. The support seat 1 can be fixedly installed on the transverse inclined bridge frame 5 to support the support rail 2, making the support rail 2 more stable. The support rail 2 is set on the support seat 1. In this embodiment, the support rail 2 can be laid along the support seat 1. That is to say, the support rail 2 is laid on the transverse inclined bridge frame 5. The support rail 2 provides bottom support and guidance for the loading wheel 4, so that the loading wheel 4 can move along the support rail 2. The pressure of the entire trolley, i.e., the loading trolley, is transmitted to the original steel frame, i.e., the transverse inclined bridge frame 5, through the support rail 2 and the support seat 1. A U-shaped limiting member 3 is provided above the support rail 2 on one side of the support rail 2, i.e., the side facing away from the other support rail 2. The U-shaped limiting member 3 is fixedly installed on the vertical inclined bridge frame 6, so that the feeding wheel 4 is partially placed in the U-shaped groove of the U-shaped limiting member 3 to guide the feeding wheel 4 and prevent it from derailing or falling off, that is, to prevent the feeding wheel 4 from separating from the support rail 2, and further ensure the stability of the feeding wheel 4. The lower flange plate of the support base 1 is connected to the transverse inclined bridge frame 5 by welding, and the U-shaped limiting member 3 is connected to the vertical inclined bridge frame 6 by welding. Of course, other connection methods can also be used, and no limitation is made in this embodiment.
[0022] In this embodiment, a fixing plate 7 may be provided on the support base 1, one end of which is fixedly installed on the top wall of the support base, and the other end is pressed against the lower flange plate of the support rail 2, so that the support rail 2 can be fixedly installed on the support base 1. Specifically, each support base 1 has a fixing plate 7 at both ends of the upper flange plate (relative to the left and right ends of the upper flange plate of the support base 1). Figure 1 (As shown in the diagram) Each of the following locations is provided with a fixed pressure plate 7. One end of the fixed pressure plate 7 can be fixedly installed on the upper flange plate of the support base 1, and the other end can have a clamping notch, which is adapted to the lower flange plate of the support rail 2 so that the lower flange plate of the support rail 2 is clamped at the clamping notch. The fixed pressure plate 7 clamps the lower flange of the support rail 2 and is fixedly installed on the upper flange plate of the support base 1, thereby achieving the fixation between the lower flange plate of the support rail 2 and the upper flange plate of the support base 1, that is, achieving the fixed connection between the support rail 2 and the support base 1. In this embodiment, the fixed pressure plate 7 and the upper flange plate of the support base 1 can be fixed by bolts, but other methods can also be used. This embodiment does not limit the methods. There can be multiple fixed pressure plates 7, which are arranged at intervals along the length direction of the support base 1 and the support rail 2.
[0023] See also Figure 1 The support base 1 can be a transversely arranged H-beam, with its upper and lower flanges arranged horizontally. The support rail 2 is set on the top wall of the upper flange of the support base 1. Specifically, the support base 1 is an H-beam, and it can be arranged transversely, meaning that both the upper and lower flanges are arranged horizontally, while the web of the support base 1 is arranged vertically. It is fixedly installed on the transverse inclined bridge frame 5 via the lower flange, and the support rail 2 is supported by the upper flange. The width of the upper flange of the support base 1 (e.g., ...) Figure 1 The width of the support rail 2 (in the horizontal direction shown) is greater than the width of the lower flange plate of the support base 1, so the upper flange plate of the support base 1, which has a wider width, can be used to support the rail 2. In this embodiment, the support base 1 can be formed by splicing multiple supports together.
[0024] See also Figure 1 The support rail 2 can be a rail steel structure, i.e., a steel structure. In this embodiment, the support rail 2 is a transversely arranged H-shaped steel structure, with its upper and lower flanges arranged horizontally and its web arranged vertically. The lower flange of the support rail 2 is fixed by a fixing plate 7, and the upper flange of the support rail 2 serves as a track to support and guide the loading wheel 4.
[0025] See also Figure 1 The U-shaped limiting component 3 can be a limiting channel steel structure. The limiting channel steel can limit the movement of the wheel 4 within the U-shaped groove of the U-shaped limiting component 3, thus preventing derailment.
[0026] In this embodiment, based on the actual site conditions, the corresponding track steel structures are spliced according to the dimensions specified in the drawings to form the support rail 2. After splicing, the rails are fixed using fixing plates 7. During fixing, the fixing plates 7 are arranged at intervals. We use manual hoists for installation, and personnel use fixed steel ladders for welding and installation. When installing the tilting guide rail, the interval is measured first, and the upper and lower base plates are installed according to the measured interval. After installation, debugging is carried out. During debugging, a no-load test is conducted first, followed by a test run with materials. After the test run is completed, the interval is measured to ensure it meets the design requirements.
[0027] In this embodiment, the loading wheel 4 is subjected to quenching and tempering treatment.
[0028] In summary, the double-chamber kiln feeding track provided in this embodiment utilizes the concept of train tracks, applying this track design to a double-chamber lime kiln. Support rails 2 are laid continuously under the U-shaped limiting component 3 on the existing inclined bridge, allowing the pressure of the feeding wheels 4 to be transmitted to the original steel frame via the support rails 2 and support seats 1. The support rails 2 support and guide the feeding wheels 4, while the U-shaped limiting component 3 provides restraint. This results in higher overall track strength for the double-chamber kiln, significantly reducing the maintenance frequency of the inclined bridge, extending the service life of the inclined bridge and the lime kiln, and preventing the feeding trolley from derailing or even falling due to wear and deformation of the steel surface of the contact groove between the feeding track and the wheels. It also solves the problem of feeding wheels getting stuck due to installation errors. This double-chamber kiln feeding track can extend its service life by more than 10 years, playing a crucial role in the normal production of the lime kiln.
[0029] The steel rails are laid continuously beneath the channel steel, allowing the pressure of the entire trolley to be transmitted to the existing steel frame. To complement the rails, we designed new loading trolley wheels, which undergo quenching and tempering treatment. Multiple layers of reinforced ribs are used at the curved sections of the loading bridge rails. This method ensures that the upper and lower wheels move within the rails, guaranteeing the overall service life. The rails are fixed using rail clamps, with spacing set according to the drawings.

This is only for the convenience of description and does not indicate or imply that the device or element must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of this utility model.
[0031] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly.
