Description

Technical Field

[0001] The utility model relates to the technical field of bulk material loading and unloading machinery, and in particular to a fixed double-tail car system capable of realizing two feeding modes of straight-through and split-flow and a bucket wheel stacker and reclaimer thereof. Background Art

[0002] Bucket-wheel stacker-reclaimer is widely used in raw material yards of mines, ports, thermal power plants, steel mills, coking plants, cement plants and chemical enterprises to transport and convey bulk materials such as ore, coal and coke. It is a large-scale, high-efficiency mobile mechanical equipment for continuous handling and loading and unloading of bulk materials.

[0003] The bucket wheel stacker reclaimer runs on the track of the bulk material raw material yard. Its main function is to stack the materials delivered by the ground belt conveyor to the material yard. It can also take materials from the piles on both sides of the track and send them to the designated location through the ground belt conveyor.

[0004] During the reclaiming operation, the bucket wheel rotates to dig up the materials on the raw material yard, and the materials are unloaded onto the cantilever belt conveyor through the unloading device. The cantilever belt conveyor sends the materials to the central funnel of the stacker-reclaimer and unloads them onto the ground belt conveyor.

[0005] During the stacking operation, the ground conveyor belt passes through the tail car to unload the materials onto the cantilever conveyor, and the cantilever conveyor throws the materials to the material yard. By adjusting the rotation angle and pitch angle of the equipment, the position of the drop point and the drop difference can be changed to form a certain shape of the pile to meet the actual needs.

[0006] It can be seen that the structural form of the tail car is directly related to the flow direction of materials in the stacking and reclaiming system, and is of great significance to the adaptability of the material field, saving investment, flexible scheduling, and maximizing the utilization rate of the material field. Most of the existing domestic bucket wheel crane tail cars are single return or pass-through, with a relatively simple operation mode, insufficient flexibility in material field scheduling, and low utilization of the site and equipment.

[0007] For stackers and reclaimers, there is a material yard process called straight-through, which is also widely used in practice. The process requirement is: the materials from the ground belt conveyor "bypass" the stacker and reclaimer, and are transported to other destinations outside the yard by the ground belt conveyor. In the prior art, there are bucket wheel stackers and reclaimers with a straight-through function, and the straight-through and diversion requirements can be achieved by adjusting the flap through a flap device. However, when switching between the straight-through function and the diversion function, the main machine or the ground belt conveyor needs to be stopped for cooperation, which reduces production efficiency and other problems. Summary of the invention

[0008] According to the above, a fixed double-tail car system and bucket wheel stacker and reclaimer with dual functions of straight-through and diversion are proposed to solve the problems of single operation mode of the central bucket wheel stacker and reclaimer in the existing technology and poor flexibility of the material yard. The operation mode is diversified and simplified, and multiple operation functions can be performed under different working conditions in different material yards, making the scheduling of the material yard more flexible.

[0009] The technical means adopted by the utility model are as follows:

[0010] A fixed double tail car system with direct and diversion dual functions, comprising: two tail cars, two tail car belt conveyors, a relay tail car, a relay tail car belt conveyor, a tail car fork funnel, a ground belt conveyor I and a ground belt conveyor II;

[0011] The tail car bifurcated funnel is a three-way flow guide tube structure with one inlet and two outlets, specifically an inverted Y-shaped flow guide tube structure that enters from the top and guides downward. A flap device for controlling the diversion direction is provided at the intersection of the three pipelines inside the tail car bifurcated funnel. The flap device can complete at least two working conditions, one is a one-to-two diversion working condition in the middle position, and the other is a one-to-one single-pass working condition that completely blocks one of the pipelines.

[0012] The outlet of one pipeline of the tail car fork funnel is connected to the inlet of the relay tail car belt conveyor, and the outlet of the other pipeline of the tail car fork funnel is connected to the inlet of the ground belt conveyor II.

[0013] Furthermore,

[0014] A chute and a material-dropping buffer device are provided at the outlet position of the pipeline connecting the forked funnel of the tail car and the ground belt conveyor II, and the outlets of the chute and the material-dropping buffer device are connected to the inlet of the ground belt conveyor II.

[0015] Furthermore,

[0016] The above-mentioned flap device comprises: a flap and an adjusting hydraulic cylinder;

[0017] The bottom of the above-mentioned flap is hinged to the intersection of the three pipelines inside the tail car fork funnel, the telescopic part of the hydraulic cylinder is adjusted to be hinged to the middle side wall of the flap, and the tail of the cylinder body of the hydraulic cylinder is adjusted to be hinged to the inner wall of the tail car fork funnel, and then the flap is driven to flip by adjusting the telescopic part of the hydraulic cylinder to realize the switching of the two working conditions of the flap device.

[0018] Furthermore,

[0019] The above-mentioned relay tail car is connected to the traveling device of the bucket wheel stacker and reclaimer in the form of a connecting rod.

[0020] The utility model also provides a fixed double-tail car system that can realize two feeding modes of straight-through and diversion. The flap device adjusts the hydraulic oil cylinder through the hydraulic system to perform flipping movement at the front, middle and rear positions. When the hydraulic system flap device is adjusted to the rear side (the direction of the second tail car) through the control system, the second tail car mechanism is converted into a stacking state. The materials transported from the ground belt conveyor I first pass through the second tail car belt conveyor, then pass through the second tail car head funnel, enter the tail car fork funnel, and then fall into the relay tail car belt conveyor, and then pass through the relay tail car head funnel again and fall onto the cantilever belt conveyor of the bucket wheel stacker (stacking state), and finally stack the materials in the material yard, that is, the two tail car mechanism realizes the stacking state. When the flap device is flipped to the front side (towards the relay tail car), the straight-through function can be realized. The material transported from the ground belt conveyor Ⅰ to the second tail car belt conveyor falls onto the chute and the material drop buffer through the tail car fork funnel, that is, it falls onto the ground belt conveyor Ⅱ, realizing the straight-through function. When the tail car flap device is flipped to the middle position, part of the material sent from the ground belt conveyor Ⅰ to the second tail car falls onto the relay tail car belt conveyor through the tail car fork funnel to realize the stacking function, and part of the material falls onto the ground belt conveyor Ⅱ to realize the straight-through function, which can realize the diversion function. The double tail car system of the utility model can realize the functions of multiple operations under different working conditions in different material yards, making the scheduling of the material yard more flexible.

[0021] Compared with the prior art, the utility model has the following advantages:

[0022] 1. The bucket wheel stacker and reclaimer using the technology of the present application can not only stack materials but also reclaim materials and have functions such as direct flow and diversion, which reduces the number of equipment, thereby reducing the user's land area and greatly reducing the user's one-time investment cost and subsequent use and maintenance cost.

[0023] 2. Compared with the traditional reversing two-tail car structure, the function switching structure of the present application technology is simple and convenient, the belt cleaning effect is better after switching, and the material conversion form is fast and convenient.

[0024] 3. It can realize multiple operating functions under different working conditions, and the material yard scheduling is more flexible.

[0025] 4. The tail car has a low height, short length, and low height of the main machine, which can not only reduce the manufacturing cost of the corresponding bulk material machinery of the equipment manufacturer, but also reduce the civil construction cost of the ground foundation, and at the same time improve the utilization rate of the material yard.

[0026] 5. The mode switching process between the straight-through function and the stacking function does not require the host machine or the ground to stop, which effectively ensures the production efficiency of the stacker-reclaimer.

[0027] In summary, the technical solution of the present application can solve the problems in the prior art that the stacker and the reclaimer are arranged separately, occupying a large area, having low utilization efficiency, requiring large user investment, the equipment occupies a large width of the material yard, resulting in a small width of the material pile and a small storage capacity of the material pile, the stacker and the reclaimer are arranged separately and the overall weight of the equipment is high, the stacker and the reclaimer each need to be equipped with a separate ground belt conveyor system, which has a high cost, the stacker and the reclaimer each need to be equipped with two ground tracks, and the ground foundation cost is high.

[0042] See also Figure 1-Figure 5 As shown, the utility model provides a fixed double-tail vehicle system with dual functions of direct flow and diversion.

[0043] Specifically, the present embodiment provides a double tail car system of a bucket wheel stacker and reclaimer, wherein the tail car part mainly includes a relay tail car 3 and a second tail car 1, wherein the relay tail car 3 is mainly used to transfer the material delivered by the ground belt conveyor Ⅰ11 to the second tail car belt conveyor 2, and then transfer the material to the cantilever belt conveyor 13 of the bucket wheel stacker after passing through the relay tail car 2, so as to realize the transfer and transportation between materials, wherein the relay tail car 3 is connected to the second tail car 1, and the second tail car belt conveyor 2 in the second tail car 1 is connected to the ground belt standby Ⅰ11, and the materials are transported to the second tail car 13 by the relay tail car 2. When transporting materials, the second tail car belt conveyor 2 can be used as a part of the ground belt conveyor Ⅰ11 to dock with the ground belt conveyor Ⅰ11 and transport materials. The connection between the relay tail car 3 and the second tail car 1 is mainly connected through the forked funnel 5 structure in the material transfer. The forked funnel 5 is connected to the second tail car head funnel 9 on the top, and one side of the lower fork is connected to the relay tail car tail guide trough 15, and the other side is connected to the bottom chute 10. The chute part is connected to the buffer device and then falls to the ground belt conveyor Ⅱ16. Among them, the tail car forked funnel 5 is equipped with a flap device 6 controlled by a hydraulic system 7. The flap device 6 can be adjusted in the front, middle and rear positions to achieve the corresponding conversion of the working state.

[0044] Specifically, there are three working states of the tail car (second tail car and relay tail car), namely, stacking position ( Figure 3 ) and pass-through position ( Figure 4 ) and the shunt position ( Figure 5 ), the tail car is mainly realized in stacking, straight-through and diversion conversion through the flap device 6, and the hydraulic cylinder provides driving force to push the flap 61 in the flap device to switch between the front, middle and rear positions accordingly. When stacking, the hydraulic system controls the cylinder to flip the flap toward the direction of the tail car. When the tail car flap device touches the right limit element of the tail car, the right limit element senses the signal and transmits the signal to the control device. After the control device receives the signal, the flap device is pushed to the right position. At this time, the tail car is in the stacking position ( Figure 3 ) working state, when the tail car is in the stacking position state, the material can be transported to the second tail car belt conveyor 2 connected to the ground belt conveyor through the ground belt conveyor Ⅰ during transportation, and then through the receiving effect of the funnel on the relay tail car 3, the material is transferred to the relay tail car belt conveyor 3 through the flip device 6, and then transferred to the cantilever belt conveyor 13 through the relay tail car, and the material is transported to the material yard through the cantilever belt conveyor, realizing the transportation of stacked materials, simple and convenient operation, and realizing the transfer transportation of materials between the ground belt conveyor and the cantilever belt conveyor.

[0045] The tail car is converted to a through-car ( Figure 4 ) state, the hydraulic system controls the oil cylinder to make the flap 61 flip in the direction of the main machine (the main part of the bucket wheel stacker and reclaimer). When the tail car flap device 6 touches the left limit original of the tail car, the left limit element senses a signal and transmits the signal to the control device. After the control device receives the signal, the flap device 6 is pushed to the left position, and the tail car is in the straight-through working state. When the tail car is in the straight-through state, the material can be transported to the second tail car belt conveyor 2 connected to the ground belt conveyor through the ground belt conveyor 11 during transportation, and then through the receiving effect of the head funnel on the relay tail car, the material is transferred to the chute through the flap device 6 and then falls onto the falling buffer device 10 of the ground belt conveyor, and then transported to the front ground belt system through the ground belt conveyor 11 again, realizing the straight-through function of the material, which is simple and convenient to operate, and realizing the function of the ground belt conveyor directly conveying the material to the ground belt conveyor;

[0046] When the tail car is converted to a diversion ( Figure 5 ) state, the hydraulic system controls the oil cylinder to flip the flap 61 to the middle position, and the oil cylinder is used to keep the flap in the middle position at all times. The position here can satisfy the function of stacking part of the materials and passing through the other part of the materials. The stacking and passing through diversion flow control can be controlled by the flap device 6 at different positions in the middle. This function realizes that a part of the materials transported by the ground belt conveyor can be stacked, and the other part of the materials can also meet the function of passing through directly.

[0047] The double tail car system in this embodiment greatly improves the site adaptability of the bucket wheel stacker, and there is no need to configure a special belt conveyor system for the bucket wheel stacker. Compared with the prior art, the flap device is flexible to convert, compact in structure, safe and reliable, so that the bucket wheel stacker has multiple operating functions under different conditions in different material yards. Especially for material yards with large-volume and long-distance ground belt conveyor systems, the bucket wheel stacker with a double tail car system can adapt well to the operation scheduling requirements without a special belt conveyor system, making the material yard scheduling flexible.

[0048] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
