Description

Technical Field

[0001] The utility model relates to an integrated actuator for a chute gate of a mobile storage and transportation bin, which is a loading machine and a loading station mechanism for loading bulk goods onto trains or trucks. Background Art

[0002] The chute of the existing automatic loading station for bulk goods is in a fixed position, that is to say, the discharge port of the loading station is relatively fixed. In order to evenly load bulk materials into the carriage, it is usually required that the vehicle slowly move forward during the unloading process at the loading station, so that the materials gradually and evenly fill the carriage from front to back without partial load. The commonly used existing train loading stations are usually suitable for loading trains with unified carriages. During the loading process, the train moves forward at a constant speed, and the loading station only needs to cooperate with a discharge speed adapted to the vehicle speed to achieve uniform loading. However, for some special situations, such as the carriage models of the train are not unified, the train cannot achieve uniform loading during the constant-speed forward movement. The existing loading stations can only start and stop continuously for each carriage and cooperate with the front and back movement of the carriage to level the materials or manually level the materials to achieve a uniform loading state. At the same time, for the automobile loading station, there is also the same problem. During the automobile loading process, the automobile driver needs to cooperate with the loading station and slowly move forward during the loading process. However, since the control of the slow forward movement of the automobile is relatively difficult, it often cannot meet the requirement of constant-speed forward movement, so manual leveling of materials is often required. How to achieve uniform stacking of materials in the carriage and avoid partial load in the parked state is a problem that needs to be solved. Summary of the Invention

[0003] In order to overcome the problems of the prior art, the utility model provides an integrated actuator for a chute gate of a mobile storage and transportation bin. The mechanism adopts an integrated design of a storage and transportation bin, a gate and a chute. During the loading process, the storage and transportation bin moves back and forth to fill the carriage without the need for the vehicle to move back and forth, achieving uniform loading.

[0004] The purpose of the utility model is realized as follows: An integrated actuator for a chute gate of a mobile storage and transportation bin, comprising: a horizontal guide rail installed on a steel structure frame and extending along the length direction of the carriage to be loaded, a conical storage and transportation bin capable of moving along the horizontal guide rail is arranged on the horizontal guide rail, a batching facility is arranged above the conical storage and transportation bin, and the necking at the bottom of the conical storage and transportation bin is sequentially connected to a gate integrated with the conical storage and transportation bin and a discharging facility.

[0006] Further, the horizontal traction device includes: a cycloidal hydraulic motor as the driving source. The cycloidal hydraulic motor drives a sprocket chain through a coupling, and the sprocket chain pulls the conical storage and transportation bin to move horizontally along a horizontal guide rail.

[0007] Further, the batching facility is a belt conveyor or a buffer bin plus a belt conveyor.

[0021] Embodiment 1:

[0022] This embodiment is an integrated actuator for the chute gate of a mobile storage and transportation bin. As shown in Figure 1 、 2 , Figure 1 it is the application of the structure described in this embodiment at an automobile loading station, Figure 2 and it is the application of the structure described in this embodiment at a train loading station. This embodiment includes: a horizontal guide rail 3 installed on a steel structure frame 1 and extending along the long direction of the carriage 2 to be loaded ( Figure 1 ), a conical storage and transportation bin 4 capable of moving along the horizontal guide rail is arranged on the horizontal guide rail, a batching facility 5 is arranged above the conical storage and transportation bin, and the reduced opening at the bottom of the conical storage and transportation bin is sequentially connected to a gate 6 integrated with the conical storage and transportation bin and a discharging facility 7.

[0023] In order to solve the problem of uniform loading in this embodiment, a relatively small conical storage and transportation bin is adopted. The conical storage and transportation bin can move horizontally along the long direction of the carriage to be loaded (the direction of the vehicle's travel, Figure 1 the direction of arrow A in the figure). The conical storage and transportation bin is a small bin with a capacity of 40 - 60 tons and is used for batching and loading. This is because the loading capacity of a truck is usually less than 50 tons, and the loading capacity of a railway gondola car is less than 120 tons. Setting the conical storage and transportation bin with a capacity of 40 - 60 tons can meet the requirement of filling a truck with a single batching or filling a gondola car with two batchings.

[0024] The batching facility can be a belt conveyor, that is, the bulk material is directly conveyed by the belt conveyor into the conical storage and transportation bin for batching. This method is suitable for an automobile loading station. A truck can be filled with 40 tons of batching at a time, and the batching time is short, which can fully keep up with the rhythm of automobile loading. At this time, the role of the conical storage and transportation bin is a buffer bin, that is, the belt conveyor continuously supplies materials to the conical storage and transportation bin. When loading, a metering device is arranged in the discharging facility to measure the bulk material unloaded into the carriage, generating the function of quantitative loading.

[0025] When loading a railway gondola car, since the loading speed is fast, the conical storage and transportation bin needs to batch materials quickly. Therefore, a buffer bin for batching with a belt conveyor can be arranged above the conical storage and transportation bin, and a weighing device is arranged on the conical storage and transportation bin to transform the conical storage and transportation bin into a quantitative bin, realizing the automatic quantitative loading of a railway gondola car with quick batching, weighing, and discharging.

[0026] The horizontal movement of the conical storage and transportation bin can be achieved in various ways. One of them is to install rollers on the conical storage and transportation bin, which roll on the horizontal guide rail. Driven by a motor or an oil motor, it drives the sprocket chain or the roller and the wire rope for traction, thereby enabling the conical storage and transportation bin to move on the horizontal guide rail, and realizing the overall movement of the conical storage and transportation bin, the gate, and the chute along the length direction of the carriage. During loading, the loader only needs to guide the driver to drive the vehicle to the designated parking space (the parking space is below the conical storage and transportation bin) to stop, or the train driver to park the carriage at the designated parking space. The movable storage bin, the gate, the chute and other discharging facilities move along the front and back direction of the carriage during the loading process, and the position of its material dropping port continuously moves as the material accumulates in the carriage, moving from the front end of the carriage to the rear end of the carriage (see Figure 1 , 2 where the conical storage and transportation bin moves from the solid line position to the dotted line position along the arrow A direction) or vice versa to fill the entire carriage. During the process of filling a carriage, the vehicle or the train does not need to move back and forth during loading. As long as it stops, the carriage can be filled.

[0027] The conical storage and transportation bin is designed to be conical so that it can receive batching within a large range during the movement process. As shown in Figure 1 , the conical storage and transportation bin moves within the discharging range before and after a carriage, and can simultaneously receive the batching from the fixed batching belt conveyor. In order to reduce the inclined cone angle of the conical storage and transportation bin, a distributing machine can be set between the belt conveyor and the conical storage and transportation bin to transfer the material back and forth and then enter the conical storage and transportation bin without scattering.

[0028] The horizontal cross-sectional shape of the described conical storage and transportation bin can be a rectangular pyramid cylinder or a long conical cylinder. The bottom of the conical storage and transportation bin is connected to a conical reduced opening, and a gate is set at the reduced opening as the discharging port. A gate is set on the discharging port.

[0029] The discharging gate at the bottom of the storage bin can be a flat double-wing gate or a swinging gate, or other forms of gates.

[0030] There can be various schemes for the described discharging facilities. If the storage bin has the weighing ability, the discharging setting does not need to be equipped with a metering device, and direct discharging or discharging through a chute can be adopted. If the storage bin does not have the weighing ability, a device with a weighing function is set in the discharging facilities, such as adopting a short belt conveyor with weighing ability and other methods.

[0031] To enable the material to smoothly enter the carriage and avoid the collision between the head of the vehicle or the head of the train and the conical storage and transportation bin, a chute can be set below the discharging port. The chute can be a telescopic chute or a swinging chute.

[0032] In order to prevent materials from being lost during the unloading process, which would pollute the environment and cause material loss, sealing facilities can be installed between the conical storage and transportation bin and the chute.

[0033] The conical storage and transportation bin and the chute are connected with high-strength lining to prevent wear.

[0034] Dovetail-shaped coal levelers can be installed on both sides of the chute outlet (in the direction of vehicle travel) to adjust the height of the material pile and complete the shaping to ensure the flat coal effect. Guard plates are installed on both sides of the chute outlet. The chute is equipped with an inspection door to facilitate the cleaning and maintenance of materials.

[0035] The device described in this embodiment adopts a mobile integrated conical storage and transportation warehouse loading method. After the vehicle stops at the position point, the chute moves to the unloading position, and the gate is started to start unloading. The material flow enters the car along the chute, and then the conical storage and transportation warehouse and the chute move along the guide rail together to load the rear of the car, and the gate opening is adjusted to control the material flow rate. During the loading process of the car, the chute, the conical storage and transportation warehouse, and the gate are pulled and moved as a whole by the traction pulley group. Unlike traditional storage and transportation warehouses (quantitative warehouses or buffer warehouses) that cannot be moved, and the vehicle needs to be driven forward and backward according to the instructions of the loader during loading, the mobile storage and transportation warehouse and its chute and gate of this embodiment do not require the vehicle to move during loading. The conical storage and transportation warehouse and chute can move on the track according to the loading situation of the car, and can automatically adjust the position of the unloading port according to the position of the car, and adjust the gate opening according to the position of the unloading port and the state of the stacking in the car, so that the material loaded in the car forms a uniform stack. The unloading process is as follows Figure 3 shown.

[0036] Embodiment 2:

[0037] This embodiment is an improvement of the first embodiment and is a refinement of the horizontal guide rail of the first embodiment. The horizontal guide rail of this embodiment is provided with rollers 301 in a row, the four corners of the conical storage and transportation bin are fixedly connected to a slide 401 that can slide on the rollers of the horizontal guide rail, and the conical storage and transportation bin is moved on the horizontal guide rail by traction of a lateral traction device.

[0038] Rollers are installed in rows on horizontal guide rails. Slide plates that can slide on the horizontal guide rails are installed at the four corners of the conical storage and transportation warehouse. The slide plates are fixedly installed on the cone of the conical storage and transportation warehouse, and the slide plates slide on the horizontal guide rails. The power for the movement of the conical storage and transportation warehouse comes from the lateral traction device. The lateral traction device can be driven by a hydraulic motor or sprocket chain traction, or other methods.

[0039] Embodiment three:

[0040] This embodiment is an improvement of the above embodiment and a refinement of the above embodiment regarding the lateral traction device. The lateral traction device described in this embodiment includes: a cycloidal hydraulic motor as the driving source. The cycloidal hydraulic motor drives a sprocket chain through a coupling, and the sprocket chain drives the conical storage bin to move horizontally along the horizontal guide rail.

[0041] The lateral traction device is driven by a cycloidal hydraulic motor to rotate the sprocket, and the sprocket drives the chain to traction the conical storage bin to move horizontally. A limit switch is installed on the horizontal guide rail to limit the movement range of the conical storage bin. When loading and unloading, the conical storage bin, the gate and the chute move together on the guide rail. When the chute aligns with the carriage, the gate automatically opens and unloads. The opening of the gate is adjusted by a servo motor.

[0042] Embodiment Four:

[0043] This embodiment is an improvement of the above embodiment and a refinement of the above embodiment regarding the batching facility. The batching facility described in this embodiment is a belt conveyor or a buffer bin 501 plus a belt conveyor 502, as Figure 2 shown.

[0044] Since the one-time loading capacity of the truck loading station is less than 50 tons and the loading capacity is small, a 60-ton conical storage bin can meet the needs. For batching the conical storage bin, long-distance belt conveying can be used to directly convey the bulk materials piled up in the silo or the stockyard to the conical storage bin, as Figure 1 shown.

[0045] The loading capacity of a train car body is relatively large. Usually, two bins of materials are needed to fill one car body. Therefore, in this embodiment, a buffer bin is added to enable the conical storage bin to batch materials quickly, reduce the waiting time, and improve the loading efficiency.

[0046] Embodiment Five:

[0047] This embodiment is an improvement of the above embodiment and a refinement of the above embodiment regarding the batching facility. A distributing machine 503 is provided between the batching facility described in this embodiment and the conical storage bin, as Figure 2 shown.

[0048] When the length of the carriage is long, such as a train car body, the conical storage bin needs to move a long distance to evenly fill a car body with bulk materials. For this reason, a distributing machine can be set below the batching facility and above the conical storage bin, so that the bulk materials can move horizontally for a certain distance to adapt to the horizontal movement of the conical storage bin without spilling the bulk materials. The distributing machine can be a device such as a short belt conveyor or a guiding chute.

[0049] Embodiment Six:

[0050] This embodiment is an improvement of the above embodiment and a refinement of the above embodiment regarding the gate. The gate described in this embodiment is a double-wing gate.

[0051] The double-wing gate is divided into two wings, A and B, and can open on the left and right sides, thus realizing the process of material falling and loading into the vehicle. A vibrating variable-frequency feeder is installed below the gate, and the frequency of the feeder can be adjusted by frequency conversion, thereby realizing the controllable control of the discharging speed.

[0052] Embodiment Seven:

[0053] This embodiment is an improvement of the above embodiment and a refinement of the above embodiment regarding the discharging facility. The discharging facility described in this embodiment includes: a variable-frequency metering feeder, and a short conveyor belt for the metering feeder is provided below the variable-frequency metering feeder.

[0054] The vibrating feeder is driven by a variable-frequency motor below the conical storage bin's discharging port for discharging operations. By setting the frequency of the feeder, rapid batching, slow batching, and precise batching processes can be achieved. The frequency can be adjusted from 0 to 50 Hz, and finally, rapid and quantitative loading can be realized.

[0055] The short conveyor belt for the metering feeder described in this embodiment is a device for measuring the loading quantity, used to measure the quantity of the materials loaded into the vehicle, and can control the quantity of the materials loaded into the vehicle in order to achieve the purpose of quantitative loading. The short conveyor belt for the metering feeder adopts a constant-value belt scale design. Given the required tonnage of the rated weight of the materials, the constant-value belt scale starts automatically. A physical connection between the PLC and the constant-value belt scale is created. The CPU is connected to the constant-value belt scale instrument using a profibus DP cable. The GSD file is installed, the PG / PC INTERFACE is set, the MPI PC adapter is selected and the transmission rate and USB interface are selected. The address and transmission rate are configured through step7 and the PLC is downloaded. A 48-bit I / O address is allocated, and the parameter configuration and status display are completed using the MOV instruction.

[0056] Embodiment Eight:

[0057] This embodiment is an improvement of the above embodiment and a refinement of the above embodiment regarding the discharging facility. A chute is further provided below the short conveyor belt for the metering feeder of the discharging facility described in this embodiment.

[0058] The chute can reduce the dust generated during the discharging of bulk materials, guide the accumulation of bulk materials in the carriage, and can level the top of the material pile. The chute can be a vertical telescopic chute or a swinging chute.

[0059] Embodiment Nine:

[0060] This embodiment is an improvement of the above embodiment and a refinement of the above embodiment regarding the discharging facility. The chute described in this embodiment is a vertical telescopic chute.

[0061] The vertical telescopic chute is provided with a pull rod cylinder for performing vertical movement, a chute inner barrel and a chute outer barrel. The upper part of the pull rod cylinder is hinged to the chute inner barrel, and the lower part is hinged to the chute outer barrel. A power-off lifting protection mechanism is designed, which can be lifted to a safe position in case of automatic power-off of the system to prevent the collision between the wagon and the chute.

[0062] Embodiment Ten:

[0063] This embodiment is an improvement of the above embodiment and a refinement of the above embodiment regarding the conical storage and transportation bin. The horizontal cross-sectional shape of the conical storage and transportation bin described in this embodiment is either rectangular, as shown in Figure 4 , or oblong, as shown in Figure 5 .

[0064] The rectangular horizontal cross-sectional shape of the conical storage and transportation bin makes the structure of the conical storage and transportation bin simple, while the oblong horizontal cross-sectional shape of the conical storage and transportation bin can make better use of the area for storing bulk materials.

[0065] Finally, it should be noted that the above is only used to illustrate the technical solution of the present invention and not to limit it. Although the present invention has been described in detail with reference to the preferred arrangement, those of ordinary skill in the art should understand that the technical solution of the present invention (such as the form of the loading station, the use scenario and the loading process, etc.) can be modified or equivalently replaced without departing from the spirit and scope of the technical solution of the present invention.
