Description

Technical Field

[0001] This utility model relates to the field of conveying device technology, specifically a coal sample barrel transfer vehicle conveying system. Background Technology

[0002] In the coal production process, coal samples need to be taken at each stage. After sampling, the coal needs to be packaged into coal sample barrels for transportation. The traditional transportation method is to manually load the coal sample barrels onto a van, then transport them to the destination by van or truck, and finally manually carry them to the coal sample laboratory. This method is labor-intensive, has a low degree of automation, and the coal sample barrels are not effectively secured during transportation, making them very easy to tip over and cause collisions and damage.

[0003] Currently, patent publication number CN109230638A discloses an automatic coal sample barrel loading and unloading system. The conveyor can transport coal sample barrels in both forward and reverse directions. The tail end of the tilting frame is hinged and can dock with the conveyor, allowing it to receive or output coal sample barrels. A lifting device is installed between the bottom of the tilting frame and the floor of the carriage. This lifting device supports the tilting frame near the front of the carriage and can raise and lower the head end of the tilting frame, creating an angle between the tilting frame and the horizontal plane. Rolling components are rotatably mounted on the tilting frame to support the coal sample barrels. When loading coal sample barrels, the head end of the tilting frame is lower than the tail end. After the conveyor transfers the coal sample barrel to the tail end of the tilting frame, gravity causes the coal sample barrel to automatically move towards the head end. When unloading coal sample barrels, the head end of the tilting frame is higher than the tail end, and gravity causes the coal sample barrel to automatically move towards the tail end and be transferred to the conveyor. This system automates the loading and unloading process of coal sample barrels, eliminating the need for manual operation, reducing labor intensity, and improving operational efficiency.

[0004] As can be seen from the above-disclosed technical content, the prior art, invention CN109230638A, involves rotating rolling elements on a tilting frame to support the coal sample bucket. When loading the coal sample bucket, the head end of the tilting frame is lower than the tail end. After the conveyor transfers the coal sample bucket to the tail end of the tilting frame, the coal sample bucket automatically moves towards the head end under gravity. When unloading the coal sample bucket, the head end of the tilting frame is higher than the tail end, and the coal sample bucket automatically moves towards the tail end under gravity and is transferred to the conveyor. However, the coal sample bucket in this patent only has guardrails on both sides as shown in the figure during transportation. When the vehicle is climbing or going downhill, the coal sample bucket is very prone to moving back and forth or even tipping over, causing collisions. Therefore, its use requires high road conditions and is only suitable for plains areas, while it is more limited in more complex areas. Utility Model Content

[0005] To address the problems existing in the prior art, this utility model provides a coal sample barrel transfer vehicle transportation system, which can effectively save manpower for loading and unloading coal sample barrels, effectively fix the coal sample barrels, and ensure the safe transportation of the coal sample barrels to the coal sample laboratory.

[0006] To achieve the above objectives, this utility model provides a coal sample barrel transfer vehicle conveying system, comprising a transport vehicle, a loading / unloading assembly, and a storage assembly. The loading / unloading assembly, storage assembly, and control cabinet are installed inside the cargo box of the transport vehicle. The storage assembly connects to the loading / unloading assembly. The storage assembly also includes a storage base and storage roller conveyors. Two storage roller conveyors are fixedly mounted on the storage base via brackets. Storage limit bars are installed on both sides of the storage roller conveyors. Storage stops and rear limit blocks are fixedly mounted at the front and rear of the storage roller conveyors via brackets. A fixed support control machine is mounted above the storage roller conveyors via brackets, controlling the lifting and lowering of the fixed frame. A photoelectric sensor is fixedly mounted at the end of the storage roller conveyor near the storage stops. The end of the storage roller conveyor with the storage limit bars connects to the loading / unloading assembly. The control cabinet is connected to the loading / unloading assembly and the storage assembly via electrical wires.

[0007] In addition, the coal sample barrel transfer vehicle conveying system proposed in the above embodiments of this utility model may also have the following additional technical features:

[0008] As a further improvement of this utility model, the loading and unloading assembly includes a loading and unloading assembly base, a sliding chassis, a docking conveyor roller, a loading and unloading roller conveyor, a loading and unloading limit rail, and a loading and unloading stop bar. The sliding chassis is installed on the loading and unloading assembly base via a slide rail and an electrically controlled telescopic rod. The docking conveyor roller is installed on the sliding chassis via a bracket. Loading and unloading stop bars are set at the front and rear of the loading and unloading roller conveyor, and loading and unloading limit rails are set on both sides of the loading and unloading roller conveyor. The docking conveyor roller is installed at the outer end of the loading and unloading roller conveyor via a rotating shaft and an electrically controlled telescopic rod.

[0009] As a further improvement of this utility model, photoelectric sensors are provided at both the front and rear ends of the loading and unloading roller conveyor.

[0010] As a further improvement of this utility model, the surface of the fixed frame is provided with a rubber coating.

[0011] As a further improvement of this utility model, the docking conveyor roller, loading and unloading roller conveyor and storage roller conveyor are all equipped with drive motors, and the motors drive the rollers through gears or transmission chains.

[0012] By employing the above-described solution, this utility model possesses at least the following advantages: Compared to conventional transportation methods, by placing the coal sample barrel in the storage assembly, the coal sample barrel is secured from all directions using the storage roller conveyor, storage baffle, fixing frame, storage limit bar, and rear limit block of the storage assembly. The fixing frame can press down on the coal sample barrel from above during transportation, ensuring stability even when the coal sample barrel on the storage roller conveyor is not full. Furthermore, by utilizing the loading and unloading assembly that can automatically connect to the corresponding storage roller conveyor, the coal sample barrel can be directly loaded from the conveyor belt into the storage assembly, or directly unloaded to the automated coal sample processing line.

[0018] The coal sample barrel transfer vehicle conveying system of this utility model is described below with reference to the accompanying drawings.

[0019] In Embodiment 1 of this application, as Figures 1 to 4As shown, the coal sample barrel transfer vehicle conveying system (hereinafter referred to as "the present invention") includes a transport vehicle 1, a loading and unloading assembly 2, a storage assembly 3, and a control cabinet 4. The loading and unloading assembly 2, the storage assembly 3, and the control cabinet 4 are installed inside the cargo box of the transport vehicle 1. The storage assembly 3 is connected to the loading and unloading assembly 2. The storage assembly 3 also includes a storage base 31 and a storage roller conveyor 32. The storage base 31 is fixedly mounted with two storage roller conveyors 32 by brackets. Storage limit bars 37 are installed on both sides of the storage roller conveyors 32. Storage stops 33 and rear limit blocks 38 are fixedly mounted at the front and rear of the storage roller conveyors 32 by brackets. A fixed support control machine 35 is installed above the storage roller conveyors 32 by brackets. The fixed support control machine 35 controls the lifting and lowering of the fixed frame 36. A photoelectric sensor 34 is fixedly installed at the end of the storage roller conveyor 32 near the storage stops 33. The end of the storage roller conveyor 32 with the storage limit bars 37 is connected to the loading and unloading assembly 2. The control cabinet 4 is connected to the loading and unloading assembly 2 and the storage assembly 3 by wires. The loading and unloading assembly 2 includes a loading and unloading assembly base 21, a sliding chassis 22, a docking conveyor roller 23, a loading and unloading roller conveyor 24, loading and unloading limit bars 25, and loading and unloading stop bars 26. The sliding chassis 22 is mounted on the loading and unloading assembly base 21 via slide rails and electrically controlled telescopic rods. The docking conveyor roller 23 is mounted on the sliding chassis 22 via brackets. Loading and unloading stop bars 26 are set at the front and rear of the loading and unloading roller conveyor 24, and loading and unloading limit bars 25 are set on both sides of the loading and unloading roller conveyor 24. The docking conveyor roller 23 is mounted on the outer end of the loading and unloading roller conveyor 24 via a rotating shaft and electrically controlled telescopic rods. The loading and unloading stop bars 26 are driven to rise and fall by an electric cylinder. The two storage roller conveyors 32 fixedly installed on the storage base 31 can have one empty coal sample barrel and the other empty. After reaching the designated location, the full coal sample barrel is retrieved, and the empty coal sample barrel is transported to the equipment within the location. Alternatively, after reaching the automated coal sample processing line, the full coal sample barrel is transported to the processing line and the empty coal sample barrel is retrieved.

[0020] An automatic loading and unloading system for coal sample barrels (hereinafter referred to as "the Patent") with announcement number CN109230638A describes a system where rolling elements supporting coal sample barrels are rotatably mounted on a tilting frame. When loading a coal sample barrel, the head end of the tilting frame is lower than the tail end, and the conveyor transfers the coal sample barrel to the tail end of the tilting frame. Under the action of gravity, the coal sample barrel automatically moves towards the head end. When unloading a coal sample barrel, the head end of the tilting frame is higher than the tail end, and under the action of gravity, the coal sample barrel automatically moves towards the tail end and is transferred to the conveyor. However, the coal sample bucket of this patent only has guardrails on both sides as shown in the figure during transportation. When the vehicle is going uphill or downhill, the coal sample bucket is very easy to move back and forth or even tip over, causing collisions. Therefore, its use requires high road conditions and is only suitable for plains. It is more limited in more complex areas. In contrast, the present invention places the coal sample bucket in the storage component 3 and uses the storage roller 32, storage baffle 33, fixing frame 36, storage limit bar 37 and rear limit block 38 of the storage component 3 to fix the coal sample bucket from all directions. The fixing frame 36 can press down on the coal sample bucket from above during transportation to ensure that the coal sample bucket on the storage roller 32 remains stable even when it is not full.

[0021] This second embodiment is basically the same in structure as the first embodiment, the difference being that, as Figure 3 and Figure 4 As shown, the surface of the fixed frame 36 is provided with a rubber coating, which can effectively increase the friction and set the position in contact with the coal sample barrel as a soft material, which can better protect the coal sample barrel.

[0022] To further optimize the working efficiency of this application and improve the sensing sensitivity of the equipment, photoelectric sensors are equipped at both the front and rear ends of the loading and unloading roller conveyor 24. To make it more convenient for the control cabinet 4 to control the equipment, the docking conveyor roller 23, the loading and unloading roller conveyor 24, and the storage roller conveyor 32 are all equipped with drive motors, which drive the rollers through gears or transmission chains.

[0023] When in use, the coal sample barrel transfer vehicle conveying system is installed into transport vehicle 1, and the equipment can then be put into use.

[0024] When this utility model is used, its specific operation is as follows:

[0025] The transport vehicle 1 is equipped with a card reader and a photoelectric sensor on its exterior. The photoelectric sensor can identify the position of the vehicle and the conveyor belt through a reflector and marking lines, making it easy for the transport vehicle 1 to be aligned. The card reader can read the information transmitted by the signal transmitter at the point to know the current position of the vehicle, and select to lower the empty coal sample tank and load the heavy coal sample tank, or lower the heavy coal sample tank and load the empty coal sample tank, according to the settings. After the vehicle is aligned, the control cabinet 4 can control the transport vehicle 1 to open the rear roller shutter door.

[0026] When loading coal sample barrels, the electric cylinder installed under the docking conveyor roller 23 extends, raising the docking conveyor roller 23 to be flush with the loading and unloading roller conveyor 24. The control cabinet 4 determines which of the two storage roller conveyors 32 of the storage component 3 is empty based on the recording of the photoelectric sensor 34. The loading and unloading roller conveyor 24 raises the loading and unloading stop bar 26 on the side facing the docking conveyor roller 23. The fixed bracket control machine 35 retracts, raising the fixed frame 36. The external conveyor belt transports the coal sample barrels to the docking conveyor roller 23. The motor of the docking conveyor roller 23 drives the docking conveyor roller 23 to transport the coal sample barrels to the loading and unloading roller conveyor 24. The photoelectric sensor on the loading and unloading roller conveyor 24 records the number of coal sample barrels entering. After the loading and unloading roller conveyor 24 is full of coal sample barrels, the loading and unloading roller conveyor 24 lowers the loading and unloading stop bar 26 on the side facing the docking conveyor roller 23. The sliding chassis 22 of the loading and unloading component 2 moves along the loading and unloading component base 21 under the drive of the electric cylinder or drive motor. The track slides, aligning the loading and unloading roller 24 on the sliding chassis 22 with the empty storage roller 32. Then, the loading and unloading roller 24 rises towards the loading and unloading stop 26 at one end of the storage component 3, and the storage stop 33 equipped on the storage roller 32 corresponding to the storage component 3 rises. Then, the loading and unloading roller 24 transports the coal sample barrel to the empty storage roller 32. When the coal sample barrel enters the storage roller 32, it will pass through the photoelectric sensor 34. After the control cabinet 4 counts that there are enough coal sample barrels to fill the storage roller 32, the equipment can switch the corresponding position of the loading and unloading roller 24 of the loading and unloading component 2 as needed, so that the loading and unloading roller 24 moves to the front of the corresponding storage roller 32. After loading is completed, the fixed bracket control machine 35 presses down the fixed frame 36. The fixed frame 36 presses on the coal sample barrel cover, and the coal sample barrel is fixed together by the storage roller 32, the storage stop 33, the storage limit bar 37 and the rear limit block 38.

[0027] When unloading the coal sample bucket, the transport vehicle 1 is roughly aligned with the coal sample bucket receiving port of the automated coal sample processing line. The electric cylinder installed under the docking conveyor roller 23 extends, causing the docking conveyor roller 23 to rise and become flush with the loading and unloading roller conveyor 24. The fixed bracket control machine 35 controls the fixed frame 36 to rise. The control cabinet 4 selects to open the storage stop bar 33 of the corresponding storage component 3 as needed. At the same time, the sliding chassis 22 of the loading and unloading component 2 slides along the track on the loading and unloading component base 21 under the drive of the electric cylinder or drive motor, so that the loading and unloading roller conveyor 24 on the sliding chassis 22 is aligned with the storage roller. The motor of the storage roller conveyor 32 drives the coal sample barrel into the loading and unloading roller conveyor 24 via gears or chains. Then, the storage stop bar 33 and the loading and unloading stop bar 26 are lowered. The sliding chassis 22 of the loading and unloading assembly 2 slides along the track on the loading and unloading assembly base 21 under the drive of the electric cylinder or drive motor, so that the loading and unloading roller conveyor 24 on the sliding chassis 22 is aligned with the coal sample barrel receiving port of the coal sample automated processing line. The connecting conveyor roller 23 and the storage roller conveyor 32 simultaneously drive the coal sample barrel into the coal sample barrel receiving port of the coal sample automated processing line. Then, the loading and unloading assembly 2 begins to reciprocate.

[0028] In summary, the coal sample barrel transfer vehicle conveying system of this utility model embodiment, by placing the coal sample barrel in the storage component 3, secures the coal sample barrel from all directions using the storage roller conveyor 32, storage baffle 33, fixing frame 36, storage limit bar 37, and rear limit block 38 of the storage component 3. The fixing frame 36 can press down on the coal sample barrel from above during transportation, ensuring stability even when the coal sample barrel on the storage roller conveyor 32 is not full. Simultaneously, with the loading and unloading component 2 that can automatically connect to the corresponding storage roller conveyor 32, the coal sample barrel can be directly loaded from the conveyor belt into the storage component 3, or directly unloaded to the automated coal sample processing line.
