Description

Technical Field

[0001] This invention relates to the field of transfer machine technology, and more specifically, to a movable transfer machine with impact resistance. Background Technology

[0002] Scraper transfer conveyors are used in the transport roadways of large fully mechanized mining faces with high efficiency and high output. The two ends of the scraper transfer conveyor are connected to the conveyor and the tail of the belt conveyor of the working face, respectively, so as to transfer the coal transported by the scraper conveyor of the fully mechanized mining face from the bottom of the roadway to the belt conveyor.

[0003] Utility model patent application CN213010228U discloses a novel buffer device for a scraper conveyor. This structure enhances the stability and safety of the scraper conveyor by adding a buffer device to the head of the conveyor. The buffer plates guide the free fall distance between the coal material and the telescopic tail of the conveyor, thereby reducing the impact force of gravity on the telescopic tail of the conveyor during free fall. Multiple buffer plates can disperse the coal material as it falls, with smaller pieces falling first and larger pieces falling later, further dispersing the impact force on the telescopic tail of the conveyor.

[0004] However, in actual use, this structure suffers from several problems. During the conveying process of the scraper driven by the chain inside the transfer machine, the scraper continuously contacts the coal and generates relative forces. Consequently, over time, the bolts connecting the scraper are prone to loosening, and the scraper itself may crack and break. This necessitates frequent scraper maintenance, especially when performing maintenance inside the internal passageway with the cover at the top of the coal retaining plate. Since external personnel cannot observe the work, this poses a safety hazard. Therefore, a mobile transfer machine with impact resistance is proposed. Summary of the Invention

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a mobile transfer machine with impact resistance to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a resilient material with impact resistance.

[0007] The moving transfer machine includes a bottom plate, coal retaining plates, a top plate, a machine head, and a buffer device. The buffer device is installed on the machine head, and the bottom plate is connected to one end of the machine head. Coal retaining plates are installed on both sides of the bottom plate, and the top of the two coal retaining plates jointly supports the top plate. Chains are symmetrically laid on the bottom plate, and multiple scrapers are installed on the two chains. Slide rails are installed on the inner side of the two coal retaining plates, and the two slide rails slide with the ends of each scraper. A traveling car is supported on the two coal retaining plates, and a lifting mechanism is installed at one end of the top plate. The lifting mechanism is connected to the traveling car.

[0008] By stopping the transfer machine and starting the hydraulic pump, the hydraulic rod extends downwards, causing the rollers to slide down the lifting trough and into the travel trough. Loosening the locking rods allows the sliding connector to move within the groove at the bottom of the connecting plate, separating the lifting plate from the connecting frame. The lifting mechanism then resets, allowing maintenance personnel to enter the vehicle and pull the handle to move it along the travel trough to the side of the scraper requiring repair. The scraper is replaced by placing a support plate at the bottom of the chain, allowing the two ends of the support plate to slide against the slide rail. Two chains are then fitted onto the placement grooves, and a pressure plate is pressed onto the support plate. Pins are inserted into the corresponding positioning grooves, pressing the two chains between the support plate and the pressure plate. The support plate and pressure plate are then connected with bolts, completing the scraper replacement. Furthermore, if external personnel accidentally start the transfer machine, the chain will move at the bottom of the vehicle, preventing maintenance personnel from being affected by chain movement and thus avoiding accidents, improving the safety of maintenance personnel.

[0009] Preferably, a travel groove is provided on the inner side of the coal retaining plate, and a lifting groove is provided parallel to one end of the travel groove. Multiple handles are evenly installed on the coal retaining plate at the top of each travel groove.

[0010] Preferably, the scraper includes a support assembly, both ends of which are slidably engaged with the slide rail and are disposed at the bottom end of the chain.

[0011] A crimping assembly is provided, which is connected and fitted to a support assembly, and the crimping assembly is crimped onto the top of the chain. Preferably, the support assembly includes a support plate, the two ends of which are slidably fitted with slide rails.

[0012] Three positioning slots are evenly spaced on the top of the support plate.

[0013] Two placement slots, each located between two adjacent positioning slots, and the placement slots contain...

[0014] A connecting block is formed, and the chain is placed in the corresponding placement slot.

[0015] Two threaded grooves, each threaded groove being formed on the corresponding connecting block.

[0016] Preferably, the pressing assembly includes a pressure plate that presses against a support plate.

[0017] Three pins are evenly welded to the bottom of the pressure plate, and each pin is engaged with the corresponding positioning groove.

[0018] Two bolt holes are provided, each bolt hole being opened between every two bolt pins, and each bolt hole is perpendicular to the threaded groove. A bolt is inserted into each bolt hole, and the bottom end of each bolt is screwed into the corresponding threaded groove.

[0019] Preferably, the traveling vehicle includes a car body, which is disposed between two coal retaining plates.

[0020] Multiple rollers are installed on both sides of the vehicle body and inserted into corresponding travel slots. Two connecting brackets are symmetrically welded to the top of the vehicle body.

[0021] Preferably, each connecting frame is provided with a slot, and each connecting frame is connected and cooperated with the bottom end of the lifting mechanism through the slot.

[0022] Preferably, the lifting mechanism includes a hydraulic pump, which is mounted on the top plate.

[0023] The hydraulic rod is designed to be connected to the hydraulic pump.

[0024] A connecting plate is located at the bottom of the top plate, and the top of the connecting plate is connected to the bottom of the hydraulic rod.

[0025] Two connectors are provided, each of which is slidably mounted on the end of the connecting plate and is connected and engaged with its corresponding connecting frame.

[0026] Two locking rods, each mounted on its corresponding connector.

[0027] The bottom of the connecting plate has a sliding groove, and the tops of the two connecting parts are slidably installed in the sliding groove.

[0028] The connector includes a slider, which is slidably mounted in a groove.

[0029] The lifting plate is welded to the bottom of the slider and is connected and fitted with the slot.

[0030] The locking plate is welded to one side of the lifting plate, and the locking rod is screwed into the locking plate.

[0031] The technical effects and advantages of this invention are as follows:

[0032] 1. Compared with existing technologies, by setting up the traveling crane, traveling chute, hoisting chute, handle, and hoisting mechanism, the traveling crane is installed in the internal channel formed between the coal retaining plates connected to the machine head, making maintenance easier.

[0033] Personnel can squat on the overhead crane to maintain the scrapers on the chain, and can move the crane by pulling the handle to change the position of the maintenance personnel. This prevents external personnel from accidentally pushing the maintenance personnel to the crushing end when the transfer machine is running due to inattentive observation, thereby improving the safety of maintenance personnel and avoiding safety hazards. At the same time, the lifting mechanism can lift the crane, so that when not in use, the crane installation will not obstruct the coal conveying in the channel, thus allowing the transfer machine to operate normally.

[0034] 2. By using a support plate, positioning groove, placement groove, pressure plate, and pin, compared with the existing technology, the chain can be directly placed in the placement groove and the pin can be inserted into the positioning groove. The support plate and pressure plate can be fixed by the bolt, and the chain can be locked in place. This improves the convenience of scraper replacement. At the same time, the cooperation between the pin and the positioning groove allows the pin to distribute the force on the bolt, thereby preventing the bolt from being too stressed and loosening. This improves the stability of the scraper installation and reduces the maintenance frequency. Attached Figure Description

[0046] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0047] As attached Figure 1-8 The illustrated mobile transfer machine with impact resistance includes a base plate 1, a coal retaining plate 2, a top plate 3, a machine head, and a buffer device. A buffer device is installed on the machine head, and the base plate 1 is connected to one end of the machine head. Coal retaining plates 2 are installed on both sides of the base plate 1, and the top of the two coal retaining plates 2 jointly supports the top plate 3. Chains 5 are symmetrically laid on the base plate 1, and multiple scrapers 6 are installed on the two chains 5. Slide rails 4 are installed on the inner sides of the two coal retaining plates 2, and the two slide rails 4 slide in cooperation with the ends of each scraper 6. A traveling trolley 7 is supported on the two coal retaining plates 2. A lifting mechanism 8 is installed at one end of the top plate 3, and the lifting mechanism 8 is connected to the traveling trolley 7. By stopping the transfer machine and then starting the hydraulic pump 801, the hydraulic rod 802 extends downward, causing the roller 702 to slide down along the lifting trough 10 and into the traveling trough 9. By loosening the locking rods 805, the sliding connector 804 moves in the groove at the bottom of the connecting plate 803, allowing the lifting plate and the connecting frame 7 to... 03. After separation, the lifting mechanism 8 is reset. Maintenance personnel enter the vehicle body 701 and pull the handle 11 to move the vehicle body 701 forward along the travel groove 9 to the side of the scraper 6 that needs maintenance. The scraper 6 is replaced by placing the support plate 6011 at the bottom of the chain 5, so that the two ends of the support plate 6011 slide with the slide rail 4. The two chains 5 are respectively put on the placement groove 6013, and then the pressure plate 6021 is pressed onto the support plate 6011. The pin 6022 is inserted into the corresponding positioning groove 6012, so that the two chains 5 are pressed between the support plate 6011 and the pressure plate 6021. The support plate 6011 and the pressure plate 6021 are connected by the bolts, and the replacement of the scraper 6 is completed. At the same time, if the transfer machine is accidentally started by external personnel, the chain 5 will move at the bottom of the traveling machine 7, so that the maintenance personnel are not affected by the movement of the chain 5, thereby avoiding safety accidents and improving the safety of maintenance personnel.

[0048] As attached Figure 2 As shown, a travel groove 9 is provided on the inner side of the coal retaining plate 2, and a lifting groove 10 is provided parallel to one end of the travel groove 9. Multiple handles 11 are evenly installed on the coal retaining plate 2 at the top of each travel groove 9.

[0049] When maintenance personnel step on the overhead crane 7 and pull the handle 11, the overhead crane 7 can move along the travel trough 9. When the overhead crane 7 moves to the bottom of the lifting trough 10, it can be connected to the lifting mechanism 8 to raise the height of the overhead crane 7, thereby preventing the overhead crane 7 from obstructing the coal mine conveying channel.

[0050] As attached Figure 6 , Figure 7 and Figure 8 As shown, the scraper 6 includes a support component 601, which is slidably engaged with the slide rail 4 at both ends and is located at the bottom of the chain 5.

[0051] The crimping component 602 is connected and cooperates with the support component 601, and the crimping component 602 is crimped onto the top of the chain 5.

[0052] The support assembly 601 includes a support plate 6011, both ends of which are slidably engaged with the slide rail 4. Three positioning grooves 6012 are evenly distributed on the top of the support plate 6011.

[0053] Two placement slots 6013 are respectively opened between two adjacent positioning slots 6012, and a connecting block is formed in the placement slot 6013. The chain 5 is placed in the corresponding placement slot 6013.

[0054] Two threaded grooves 6014 are provided, each threaded groove 6014 being provided on the corresponding connecting block.

[0055] The crimping assembly 602 includes a pressure plate 6021, which is crimped onto the support plate 6011.

[0056] Three pins 6022 are evenly welded to the bottom of the pressure plate 6021, and each pin 6022 is engaged with the corresponding positioning groove 6012.

[0057] Two bolt holes 6023 are provided, each bolt hole 6023 is provided between every two bolt pins 6022, and each bolt hole 6023 is perpendicular to the threaded groove 6014. A bolt is inserted into each bolt hole 6023, and the bottom end of each bolt is screwed into the corresponding threaded groove 6014.

[0058] When replacing the scraper 6 on the chain 5, the support plate 6011 is placed at the bottom of the chain 5, so that both ends of the support plate 6011 slide with the slide rail 4. The two chains 5 are then respectively placed on the placement groove 6013. Then, the pressure plate 6021 is pressed onto the support plate 6011, and the pin 6022 is inserted into the corresponding fixed position.

[0059] The two chains 5 are pressed between the support plate 6011 and the pressure plate 6021 in the slot 6012. The support plate 6011 and the pressure plate 6021 are connected by a stud, which completes the replacement of the scraper 6.

[0060] As attached Figure 4 As shown, the traveling car 7 includes a car body 701, which is disposed between two coal retaining plates 2.

[0061] Multiple rollers 702 are installed on both sides of the vehicle body 701 and are inserted into the corresponding travel slots 9.

[0062] Two connecting brackets 703 are symmetrically welded to the top of the vehicle body 701.

[0063] Each connecting frame 703 has a slot, and each connecting frame 703 is connected to the bottom of the lifting mechanism 8 through the slot.

[0064] Rollers 702 are installed on both sides of the car body 701, and the two rollers 702 are respectively inserted into the corresponding travel grooves 9. The car body 701 can be supported by multiple rollers 702, and the car body 701 can be dragged along when the rollers 702 move. The connecting frame 703 is set to connect to the lifting mechanism 8, so that the lifting mechanism 8 can adjust the height of the car body 701. This ensures that the car body 701 can avoid obstructing the coal mine passage when the transfer machine is running normally.

[0065] As attached Figure 5 As shown, the lifting mechanism 8 includes a hydraulic pump 801, which is mounted on the top plate 3. A hydraulic rod 802 is fixedly connected to the hydraulic pump 801.

[0066] A connecting plate 803 is located at the bottom of the top plate 3, and the top end of the connecting plate 803 is connected to the bottom end of the hydraulic rod 802.

[0067] Two connectors 804 are slidably mounted on the end of the connecting plate 803 and are respectively connected and cooperated with the corresponding connecting bracket 703.

[0068] Two locking rods 805 are installed on their respective connectors 804.

[0069] The bottom of the connecting plate 803 is provided with a sliding groove, and the tops of the two connecting parts 804 are slidably installed in the sliding groove.

[0070] The connector 804 includes a slider that is slidably mounted in a groove.

[0071] The lifting plate is welded to the bottom of the slider and is connected and fitted with the slot.

[0072] The locking plate is welded to one side of the lifting plate, and the locking rod 805 is screwed into the locking plate.

[0073] By sliding the slider, the lifting plate is inserted into the slot opened in the connecting frame 703. By rotating the locking rod 805, the top of the locking rod 805 is pressed against the sliding groove, thereby fixing the position of the slider. Then, by running the hydraulic pump 801, the hydraulic rod 802 lifts the connecting plate 803, thereby lifting both sides of the traveling crane 7 along the lifting groove 10 to the top of the coal retaining plate 2, thus preventing the traveling crane 7 from blocking the coal mine passage when the transfer machine is running normally.

[0074] The working principle of this invention is as follows: When using this impact-resistant mobile transfer machine to transfer coal in a mine, and it is necessary to repair or replace the scraper 6, the machine is stopped, and the hydraulic pump 801 is started, causing the hydraulic rod 802 to extend downwards. This allows the roller 702 to slide down the lifting trough 10 and into the traveling trough 9. By loosening the locking rods 805, the sliding connector 804 moves within the groove at the bottom of the connecting plate 803, separating the lifting plate from the connecting frame 703. Then, the lifting mechanism 8 is reset, and maintenance personnel enter the vehicle body 701. By pulling the handle 11, the vehicle body 701 moves forward along the traveling trough 9 to the side of the scraper 6 that needs repair, where the scraper 6 is replaced. The support plate 6011 is placed at the bottom of the chain 5, so that both ends of the support plate 6011 slide with the slide rail 4. The two chains 5 are respectively placed on the placement groove 6013, and then the pressure plate 6021 is pressed onto the support plate 6011. The pin 6022 is inserted into the corresponding positioning groove 6012, so that the two chains 5 are pressed between the support plate 6011 and the pressure plate 6021. The support plate 6011 and the pressure plate 6021 are connected by a bolt, which can complete the replacement of the scraper 6. At the same time, if the transfer machine is accidentally started by external personnel, the chain 5 will move at the bottom of the crane 7, so that the maintenance personnel are not affected by the movement of the chain 5, thereby avoiding safety accidents and improving the safety of maintenance personnel.

[0075] This invention, by installing a crane 7 and a handle 11 inside the coal retaining plate 2, allows maintenance personnel to move within the passage during maintenance, avoiding stepping on the chain 5, thereby improving the safety of maintenance personnel. At the same time, it makes the replacement of the scraper 6 faster and more convenient, improving maintenance efficiency, and also improves the firmness of the scraper 6 installation, preventing loosening.
