Description

Technical Field

[0001] This utility model relates to the technical field of thermal power plants, specifically to a travel end stop device for a bucket wheel stacker-reclaimer. Background Technology

[0002] Thermal power plants use fossil fuels as energy sources, generating heat by burning these fuels, and then using the heat to drive steam turbine generator sets to generate electricity. Bucket wheel stacker-reclaimers are common equipment in thermal power plants and other large industrial facilities, especially in places where large quantities of bulk materials (such as coal and ore) need to be stored and transported. Their main function is to remove bulk materials from the stockpile and transport them onto a conveyor belt, or to pile materials into the stockpile.

[0003] After the bucket wheel stacker-reclaimer travels to the terminal position, the bucket wheel working on the cantilever mechanism fails to reach the edge of the coal pile designed for the coal storage yard. As a result, there is still a large area of ​​coal storage that cannot be directly unloaded or retrieved by the bucket wheel stacker-reclaimer, which reduces the production efficiency of the equipment, increases the working time of personnel and vehicles, and increases production costs such as vehicle wear and fuel consumption.

[0004] Therefore, we propose a travel end stop device for a bucket wheel stacker-reclaimer to solve the problems mentioned above. Utility Model Content

[0005] The purpose of this utility model is to provide a travel end stop device for a bucket wheel stacker-reclaimer to solve the problem mentioned in the background art that the bucket wheel fails to reach the edge of the coal pile designed for the coal storage yard, resulting in a large amount of coal storage area that cannot be directly unloaded or retrieved by the bucket wheel stacker-reclaimer, thereby reducing the production efficiency of the equipment.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a travel end stop device for a bucket wheel stacker-reclaimer, comprising an extension track and a travel track, wherein the travel wheels of the bucket wheel stacker-reclaimer move on the surfaces of the travel track and the extension track, the travel structure of the bucket wheel stacker-reclaimer is used to drive the bucket wheel stacker-reclaimer to move, and the bucket wheel stacker-reclaimer is equipped with a power cable and a reel device, the travel track and the extension track are on the same horizontal line, sensors are installed on the side walls of the travel structure of the bucket wheel stacker-reclaimer, and end stops are equidistantly distributed on both the left and right sides of the extension track. The stop structure and anchor insertion holes are provided on both sides of the travel track. The limit support structure is installed on the outer wall of the travel track. The travel structure of the bucket wheel stacker-reclaimer drives the bucket wheel machine to move on the travel track. The installed sensors can monitor the position of the bucket wheel stacker-reclaimer travel structure on the travel track in real time. By installing the terminal stop structure and anchor insertion holes, the travel structure of the bucket wheel stacker-reclaimer can have the conditions for travel extension. The position of the limit support structure can be adjusted to extend the power cable positioning signal and working position signal of the bucket wheel machine.

[0007] The limit support structure includes a first forward travel sensing position and a second forward travel sensing position. The first forward travel sensing position for limiting the working position of the bucket wheel stacker-reclaimer and the second forward travel sensing position for automatic sensing ultimate limit protection are both welded to the traveling track. The upper end of the first forward travel sensing position is provided with an ultimate limit for mechanical ultimate limit protection. When the bucket wheel stacker-reclaimer traveling structure travels to the end, the sensor can trigger the travel limit switch. After reaching the travel limit stop position, the closest horizontal distance between the tip of the bucket tooth of the cantilever mechanism of the bucket wheel stacker-reclaimer and the building boundary can not only ensure bidirectional safety collision prevention, but also minimize the blind spot of the coal stored on both sides within this distance for direct use of the bucket wheel stacker-reclaimer, effectively reducing the production costs such as labor, time and fuel consumption of the coal yard vehicles.

[0008] Preferably, a number of mounting components are evenly distributed on both sides of the extension track and the walking track. The mounting components are distributed at fixed intervals and cooperate with the pre-embedded concrete bolts in the ground to fix the extension track and the walking track to the ground.

[0009] Preferably, the mounting component includes a pad and a single-hole pressure plate vertically placed on the upper end of the pad, and a nut vertically placed on the upper end of the single-hole pressure plate. The pre-embedded bolts of the concrete support can pass through the single-hole pressure plate and the pad, and the pad contacts the single-hole pressure plate and is fixed by the nut.

[0010] Preferably, the extension track is fixed to the end of the travel track by a fastener, the fastener including a clamp and round-headed bolts evenly distributed on the surface of the clamp, the clamp being located on both sides of the connection between the extension track and the travel track.

[0011] Preferably, the terminal stop structure includes a fixed base and a stop frame installed on the upper end of the fixed base, and a circular buffer plate for bearing the impact force is welded on the side wall of the stop frame.

[0012] Preferably, the anchor socket includes a mounting base, and the surface of the anchor socket is coated with a protective coating. The mounting base is fixed to the ground for use.

By installing the end stop structure and anchor socket, and adjusting the position of the limit bracket structure, the power cable positioning signal and working position signal of the bucket wheel stacker-reclaimer are extended, so that the bucket wheel stacker-reclaimer walking structure has multiple protection conditions for travel extension, effectively reducing the production costs such as labor, time, and fuel consumption when using coal yard vehicles.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1: Please refer to Figures 1-4 A bucket wheel stacker-reclaimer traveling end stop device includes an extension rail 1 and a traveling rail 2. The bucket wheel stacker-reclaimer traveling structure 4 moves on the surfaces of the traveling rail 2 and the extension rail 1. The bucket wheel stacker-reclaimer is equipped with a power cable and a reel device. An extension rail 1 is set at the end of an adjacent side of the traveling rail 2. The traveling rail 2 and the extension rail 1 are on the same horizontal line. Fixing members 3 are fixedly installed on both sides of the traveling rail 2. Sensors 5 are installed on the side walls of the traveling structure 4 of the bucket wheel stacker-reclaimer. End stop structures 6 are evenly distributed on both sides of the extension rail 1. Anchor insertion holes 7 are also provided on both sides of the traveling rail 2. The anchor insertion holes 7 are used in conjunction with the anchor pins of the maintenance position of the bucket wheel stacker-reclaimer. Limiting devices are installed on the outer wall of the traveling rail 2. The limit support structure 8 and the bucket wheel stacker-reclaimer walking structure 4 drive the bucket wheel machine to move on the walking track 2 and the extension track 1. The sensor 5 can monitor the position of the bucket wheel stacker-reclaimer walking structure 4 on the walking track 2 in real time. The extension track 1 is fixed to the end of the walking track 2 by the fixing part 3. By installing the end stop structure 6 and the anchor insertion hole 7, the bucket wheel stacker-reclaimer walking structure 4 can have the conditions for extension of the walking. The position of the limit support structure 8 is adjusted, and the power cable of the extension bucket wheel machine is connected to the signal of arrival and the working position signal. (The bucket wheel stacker-reclaimer is equipped with a lifting mechanism, conveying mechanism, stacking and reclaiming mechanism, bucket wheel stacking and reclaiming mechanism, drive mechanism and operating platform and other components, which can realize material stacking and reclaiming, which is the existing technology).

[0023] The limit support structure 8 includes a first forward travel sensing position 81 and a second forward travel sensing position 82. The first forward travel sensing position 81, used for the working position limit protection of the bucket wheel stacker-reclaimer, and the second forward travel sensing position 82, used for automatic sensing ultimate limit protection, are both welded to the extension rail 2. The upper end of the first forward travel sensing position 81 is provided with an ultimate limit 83 for mechanical ultimate limit protection. When the bucket wheel stacker-reclaimer traveling structure 4 travels to the end, the sensor 5 can trigger the travel limit switch, so that the bucket wheel stacker-reclaimer traveling structure has multiple protection conditions for travel extension. After reaching the travel limit stop position, the closest horizontal distance between the tip of the bucket tooth of the cantilever mechanism of the bucket wheel stacker-reclaimer and the building boundary can not only ensure bidirectional safety collision prevention, but also minimize the blind spot of the coal stored on both sides within this distance for direct use of the bucket wheel stacker-reclaimer, effectively reducing the production costs such as labor, time and fuel consumption of the coal yard vehicles.

[0024] After calculating the effective distance that the bucket wheel stacker-reclaimer's traveling structure 4 can actually extend, based on the length of the power cable, the distance from the edge of the coal pile, and the minimum safe distance from surrounding structures, the anchor holes 7 on both sides and the terminal stop structure 6 are marked and positioned. After positioning, the ground foundation construction of the concrete supports for the anchor holes 7 on both sides and the terminal stop structure 6 is carried out, which allows for the adjustment and fixation of the positions of the anchor holes 7 and the terminal stop structure 6.

[0025] Several mounting components 23 are evenly distributed on the left and right side walls of the extension track 1 and the walking track 2. The mounting components 23 are distributed at fixed intervals. The mounting components 23 cooperate with the pre-embedded bolts of the concrete support piers pre-embedded in the ground, so that the extension track 1 and the walking track 2 are fixed in the ground.

[0026] Mounting component 23 includes a single-hole pressure plate 231 and a pad 232 placed vertically on the upper end of the single-hole pressure plate 231, and a nut 233 placed vertically on the upper end of the pad 232. The pre-embedded bolts of the concrete support can pass through the single-hole pressure plate 231 and the pad 232, and be fixed with the nut 233, so that the extension track 2 and the travel track 1 can be fixed on the ground.

[0027] The fastener 3 includes a clamping plate 31 and round-headed bolts 32 evenly distributed on the surface of the clamping plate 31. The two ends of the clamping plate 31 can be fixed to the traveling track 1 and the extension track 2 respectively by the round-headed bolts 32.

[0028] The terminal stop structure 6 includes a fixed base 61 and a stop frame 62 installed on the upper end of the fixed base 61. A buffer plate 63 for buffering is welded on the side wall of the stop frame 62. When the stop frame 62 is used to block the bucket wheel stacker-reclaimer, the buffer plate 63 is used for buffering and blocking protection.

[0029] The anchor socket 7 includes a mounting base 71, and the surface of the anchor socket 7 is coated with a protective coating 72. The mounting base 71 is fixed to the ground for use, and together with the protective coating 72, it can protect the anchor socket 7.

[0030] In this embodiment: the bucket wheel stacker-reclaimer traveling structure 4 drives the bucket wheel machine to move on the traveling track 2. The sensor 5 can monitor the position of the bucket wheel stacker-reclaimer traveling structure 4 on the traveling track 2 and the extended track 1 in real time, triggering the travel limit switch. After reaching the travel limit stop position, the closest horizontal distance between the tip of the cantilever mechanism's bucket teeth and the building boundary ensures bidirectional safety and collision avoidance, while minimizing the blind spot for direct use of the bucket wheel stacker-reclaimer for coal stored on both sides within this distance. This effectively reduces the production costs such as labor, time, and fuel consumption associated with the use of coal yard vehicles. Furthermore, the actual extendable effective distance of the bucket wheel stacker-reclaimer traveling device is calculated based on the length of its power cable and the minimum safe distance from surrounding structures. The distance is determined by constructing concrete anchor blocks for the bucket wheel stacker-reclaimer to reach the maintenance position and terminal stop structures 6 for reaching the limit position. Anchor holes 7 and terminal stop structures 6 are installed at the new positions, enabling the bucket wheel stacker-reclaimer's traveling structure 4 to have the hardware facilities for travel extension. At the same time, the extension track 1 is fixed to one end of the traveling track 2 by the fixing parts 3, thereby extending the actual effective travel distance of the overall equipment. The limit limit bracket structure 8 is adjusted to extend the power cable positioning signal and working position signal of the bucket wheel stacker-reclaimer, so that the bucket wheel stacker-reclaimer's traveling structure has multiple protection conditions for travel extension. At the same time, the effective travel distance can reasonably match the utilization rate of the bucket wheel stacker-reclaimer with the actual storage capacity of the coal yard.

[0031] Example 2: This example is an improvement on Example 1. For details, please refer to [link / reference]. Figure 2 Several installation components 23 are evenly distributed on the ground on both sides of the extended track 1 and the walking track 2, and the installation components 23 are distributed at fixed intervals.

[0032] In this embodiment: During the process, the extension track 1 is placed at one end of the walking track 2. The extension track 1 and the walking track 2 are positioned and fixed by the concrete pre-embedded bolts and installation parts 23 embedded on the left and right sides of the track, so that the extension track 1 and the walking track 2 are fixed on the ground, which can effectively extend the travel of the bucket wheel stacker-reclaimer walking structure 4.

[0033] It should be noted that sensor 5 measures distance through a laser beam, which can accurately sense the distance between the device and the target object and provide precise position information. This is not an innovative part of this application and is common knowledge. Those skilled in the art are capable of conceiving of the specific structure and layout.
