Mine transport carriage with automatic protection function

Abstract

The present application relates to the field of mine transport equipment, especially to a mine transport carriage with automatic protection function. In the opening and closing process of the canopy cloth, if there is protruding and sharp ore in the carriage, it is easy to scratch the moving canopy cloth, leading to rapid wear and even tearing of the canopy cloth, which not only increases the maintenance and replacement cost, but also affects the reliability of the closure. A mine transport carriage with automatic protection function comprises a mounting bottom guard plate, a front wall is fixedly connected to one side of the mounting bottom guard plate, an inner frame is fixedly connected to the mounting bottom guard plate, two upright columns are fixedly connected to one side of the mounting bottom guard plate, and a connecting plate is connected between the two upright columns and the front wall. By setting a swing rod under the moving connecting bent rod and connecting an angle sensor, the protruding coal ore can be sensed, and the opening and closing movement of the canopy cloth can be stopped in time to prevent the canopy cloth from being worn or even torn.

Description

Technical Field

[0001] This invention relates to the field of mining equipment, and more particularly to a mining car with automatic protection function. Background Technology

[0002] Mining trucks are a core piece of transportation equipment in mining production. They are heavy-duty dump trucks that mainly undertake the task of transferring materials such as ore and coal. When transporting materials such as coal and ore, the truck body is in direct contact with the materials. In traditional mining trucks, the cargo is often sealed by covering it with tarpaulins or other means during transportation to prevent spillage, contamination and ensure transportation safety.

[0003] During the opening and closing of the tarpaulin, if there are protruding or sharp rocks inside the carriage, they are very likely to scratch the moving tarpaulin, causing it to wear out quickly or even be torn. This not only increases maintenance and replacement costs but also affects the reliability of the seal. Summary of the Invention

[0004] In order to overcome the shortcomings of the prior art, the present invention provides a mining car with automatic protection function that can sense ore obstructing the movement of the tarpaulin when it is opened and closed, and stop the movement of the tarpaulin in time.

[0005] The technical implementation of the present invention is as follows: a mining car with automatic protection function, comprising a bottom guard plate, a front baffle fixedly connected to one side of the bottom guard plate, an inner frame fixedly connected to the bottom guard plate, two columns fixedly connected to one side of the bottom guard plate, connecting plates connected between the two columns and the front baffle, side baffles connected between the connecting plates and the columns, the front baffle and the bottom guard plate, an arc panel fixedly connected between the upper ends of the two columns, a canopy closing mechanism provided on the connecting plate, the canopy closing mechanism being used to cover the top of the car body loaded with goods, and a door closing assembly provided on the columns, the door closing assembly being used to adapt to various unloading scenarios.

[0006] Optionally, the canopy closure mechanism includes a dual-axis motor fixedly connected to the front enclosure. Several sliding blocks are slidably connected to the side of each connecting plate, with two sliding blocks forming a group. A connecting rod is fixedly connected between the two sliding blocks in each group. A swing rod is rotatably connected to both sides of each connecting rod. An angle sensor is mounted on the shaft of the swing rod and electrically connected to the dual-axis motor. The initial state of the swing rod is vertical. A canopy fabric is arranged between the connecting rods, with one end connected to the front enclosure. A transmission wheel is rotatably connected to the side of each column and the front enclosure. A toothed chain winds between two of the transmission wheels. A pull rod is fixedly connected between the toothed chain and the side of one of the sliding blocks. A transmission assembly is connected between the output shaft of the dual-axis motor and the transmission wheel. A fixed protective shell is fixedly connected between the column and the front enclosure, with the lower surface of the fixed protective shell being inclined.

[0007] Optionally, the closing assembly includes a first tailgate, which is rotatably connected between the two pillars. A second tailgate is rotatably connected to the first tailgate. Each of the two pillars has a latch seat fixedly connected to its side. Each of the two tailgates has a latch rod rotatably connected to its sides. One end of each latch rod is bent at 90 degrees and contacts the latch seat. Each of the two pillars has a top rod rotatably connected to its side. A return spring is connected between the top rod and the pillar. The top rod is located above the latch rod.

[0008] Optionally, it also includes a side blocking mechanism for covering the side of the canopy fabric. The side blocking mechanism includes two guide plates, which are fixedly connected to the fixed protective shell. Several grooves are formed on the guide plates, and a movable baffle is slidably connected to the guide plates. Several protrusions are provided at the lower part of the movable baffle, and the lower protrusions of the movable baffle are located in the grooves on the guide plates. A limit block is fixedly connected to one side of the guide plate, and one side of the guide plate contacts the limit block. A threaded sleeve is fixedly connected to the output shaft of the dual-axis motor, and a nut is threadedly connected to the threaded sleeve. The lower end of the nut contacts the front enclosure, and a push rod is connected between the nut and the movable baffle. Several rollers are rotatably connected in the grooves on the guide plates.

[0009] Optionally, it also includes a stabilizing mechanism for maintaining stability during ore transport. The stabilizing mechanism is embedded in the inner walls of both sides of the inner frame. The stabilizing mechanism includes several rotating platforms, which are rotatably connected to the inner frame. A torsion spring is connected between the rotating platform and the inner frame. A swing top plate is rotatably connected to the rotating platform. One end of the swing top plate is provided with a toothed protrusion. A torsion spring is connected between the swing top plate and the rotating platform.

[0010] The beneficial effects of the present invention are as follows: 1. By setting a swing rod at the lower part of the moving connecting bend rod and connecting it with an angle sensor, the protruding coal ore can be sensed, and the opening and closing movement of the canopy can be controlled in time to prevent the canopy from being worn or even torn.

[0011] 2. The output shaft of the dual-shaft motor rotates forward and backward to drive the moving baffle and the tarpaulin to open and close synchronously. Since the long sides of the tarpaulin are not connected to the truck bed after it covers the top of the truck bed, the ore is prone to break out from this point when the truck is moving and bumping. The moving baffle can cover the sides of the tarpaulin to prevent the ore from breaking out and improve safety.

[0012] 3. Initially, the swing top plate is in an inclined state. When the coal ore is loaded into the car, it will be squeezed and swing downwards to become flush with the inner frame side wall as it passes over the swing top plate, thus not hindering the loading of the coal ore. After the coal ore is loaded, some of the swing top plates will return to the inclined state. The inclined swing top plates will contact the coal ore through the toothed protrusion at one end. Since the coal ore loaded in the car is stacked on top of each other, the inclined swing top plates on both sides of the inner frame can prevent the coal ore from moving upwards to a certain extent, further ensuring the stability of the coal ore during transportation. The rotating platform is rotatably connected to the inner frame, so the swing top plate does not hinder the horizontal movement of the coal ore when unloading. Attached Figure Description

Detailed Implementation

[0027] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings. It is hereby declared that the directional terms such as up, down, left, right, front, back, inside, and outside used in this text are based solely on the accompanying drawings and are not intended to specifically limit the invention. Example 1

[0028] A mining car with automatic protection function, such as Figure 1-13As shown, the system includes a mounting base plate 1, a front partition 2 fixedly connected to one side of the mounting base plate 1, an inner frame 3 fixedly connected to the mounting base plate 1, two uprights 41 fixedly connected to one side of the mounting base plate 1, connecting plates 42 connecting the two uprights 41 to the front partition 2 respectively, a side partition 43 connecting the connecting plates 42 to the uprights 41, the front partition 2 and the mounting base plate 1, an arc panel 44 fixedly connected between the upper ends of the two uprights 41, a canopy closing mechanism provided on the connecting plates 42 for covering the top of the cargo compartment, and a door closing assembly provided on the uprights 41 for adapting to various unloading scenarios.

[0029] The canopy-closing mechanism includes a dual-axis motor 51, which is fixedly connected to the front enclosure 2. Each connecting plate 42 has several sliding blocks 52 slidably connected to its side. Two sliding blocks 52 form a group, and a connecting rod 53 is fixedly connected between the two sliding blocks 52 in each group. Each connecting rod 53 has a swing rod 54 rotatably connected to both sides. An angle sensor 55 is installed on the rotating shaft of the swing rod 54, and the angle sensor 55 is electrically connected to the dual-axis motor 51. The initial state of the swing rod 54 is vertical. A canopy 56 is provided between the connecting bent rods 53. One end of the canopy 56 is connected to the front enclosure 2. The uprights 41 and the side of the front enclosure 2 are rotatably connected to transmission wheels 57. A toothed chain 58 is wound between the two transmission wheels 57. A pull rod 59 is fixedly connected between the toothed chain 58 and the side of one of the sliding blocks 52. A transmission assembly 510 is connected between the output shaft of the dual-axis motor 51 and the transmission wheels 57. A fixed protective shell 511 is fixedly connected between the uprights 41 and the front enclosure 2. The lower surface of the fixed protective shell 511 is inclined.

[0030] The closing assembly includes a first tailgate 61, which is rotatably connected between two pillars 41. A second tailgate 62 is rotatably connected to the first tailgate 61. Each of the two pillars 41 has a latch seat 63 fixedly connected to its side. Each of the two sides of the second tailgate 62 has a latch rod 64 rotatably connected to its side. One end of the latch rod 64 is bent at 90 degrees and contacts the latch seat 63. Each of the two pillars 41 has a top rod 65 rotatably connected to its side. A return spring 66 is connected between the top rod 65 and the pillar 41. The top rod 65 is located above the latch rod 64.

[0031] In actual mining operations, when loading coal ore into the truck bed, the dual-shaft motor 51 is first started, which drives the gear chain 58 to move via the transmission assembly 510. This, in turn, drives the sliding block 52 furthest from the front barrier 2 via the pull rod 59. The movement of the sliding block 52 then drives the connecting rod 53 to move, thereby causing the tarpaulin 56 to retract and expand via the forward and reverse rotation of the dual-shaft motor 51. After the tarpaulin 56 is retracted, coal ore and other goods are loaded into the truck bed. After loading, the tarpaulin 56 is expanded to cover the top of the truck bed. The horizontal movement of the connecting rod 53 causes the swing rod 54 to move as well. When the swing rod 54 contacts the coal ore loaded in the truck bed, the swing rod 54 tilts. When the swing rod 54 tilts beyond a certain angle, i.e., the shaft of the swing rod 54 rotates a certain angle, the angle sensor 55 is triggered, which controls the dual-shaft motor 51 to shut down, so that the tarpaulin 56 stops moving. Because the coal ore is irregularly shaped, if the loaded coal ore exceeds the truck bed's capacity... In some sections, protruding coal ore can easily cause the tarpaulin 56 to be worn or even torn during opening and closing, thus reducing its protective function. When the dual-axis motor 51 is triggered and shut down by the angle sensor 55, the workers tidy up or clean the coal ore according to the position where the connecting rod 53 stops, and then restart the dual-axis motor 51 to open and close the tarpaulin 56. When the truck is carrying coal ore, the locking rod 64 engages with the buckle seat 63, and the top rod 65 prevents the locking rod 64 from engaging. 4. Due to the bumps during vehicle travel, the coupling may rotate and disengage. Before unloading, first move the top rod 65 to one side, then rotate the locking rod 64 to disengage. Then tilt the cargo compartment to unload. The first tail door 61 and the second tail door 62 swing outward. The unloaded coal ore will pile up between the tail door and the cargo compartment. Since the maximum upward rotation angle of the first tail door 61 is 90 degrees due to the limit at the top of the pillar 41, the multi-section tail door can make the opening and closing angle larger. After unloading, the tail door is not easily blocked by the piled coal ore. Example 2

[0032] Based on Example 1, such as Figure 8-10As shown, it also includes a side blocking mechanism, which is used to cover the sides of the canopy 56. The side blocking mechanism includes two guide plates 71, which are fixedly connected to the fixed protective shell 511. The guide plates 71 have several grooves. A movable baffle 72 is slidably connected to the guide plates 71. The lower part of the movable baffle 72 has several protrusions. The lower protrusions of the movable baffle 72 are located in the grooves on the guide plates 71. A limit block 73 is fixedly connected to one side of the guide plates 71, and one side of the guide plates 71 contacts the limit block 73. A threaded sleeve rod 74 is fixedly connected to the output shaft of the dual-axis motor 51. A nut 75 is threadedly connected to the threaded sleeve rod 74. The lower end of the nut 75 contacts the front enclosure 2. A push rod 76 is connected between the nut 75 and the movable baffle 72. Several rollers 77 are rotatably connected in the grooves on the guide plates 71.

[0033] When the output shaft of the dual-axis motor 51 rotates and drives the canopy 56 to retract, the output shaft of the dual-axis motor 51 will drive the threaded sleeve rod 74 to rotate together. The two threaded sleeve rods 74 drive the two nuts 75 to move horizontally in a direction away from each other through the threads, which in turn drives the push rod 76 and the two movable baffles 72 to move horizontally a distance away from each other. The forward and reverse rotation of the output shaft of the dual-axis motor 51 drives the movable baffles 72 to open and close synchronously with the canopy 56. Since the long sides of the canopy 56 are not connected to the truck bed after the canopy 56 covers the top of the truck bed, if the truck bumps when it is driving, the ore may easily break out from here. The movable baffles 72 can cover the sides of the canopy 56 to prevent the ore from breaking out and improve safety. Example 3

[0034] Based on Example 2, such as Figure 11-13 As shown, it also includes a stabilizing mechanism, which is used to maintain the stability of the ore during transportation. The stabilizing mechanism is embedded in the inner walls of both sides of the inner frame 3. The stabilizing mechanism includes several rotating platforms 81, which are rotatably connected to the inner frame 3. A torsion spring 82 is connected between the rotating platform 81 and the inner frame 3. A swing top plate 83 is rotatably connected to the rotating platform 81. One end of the swing top plate 83 is provided with a toothed protrusion. A torsion spring 84 is connected between the swing top plate 83 and the rotating platform 81.

[0035] Initially, the swing top plate 83 is in an inclined state. When the coal ore is loaded into the car, it will be squeezed and swing downwards to become flush with the side wall of the inner frame 3 as it passes over the swing top plate 83, thus not hindering the loading of the coal ore. After the coal ore is loaded, some of the swing top plates 83 will return to the inclined state. The inclined swing top plate 83 will contact the coal ore through the toothed protrusion at one end. Since the coal ore loaded in the car is stacked on top of each other and squeezed and limited, the inclined swing top plates 83 on both sides of the inner wall of the inner frame 3 can prevent the coal ore from moving upwards to a certain extent, thereby further ensuring the stability of the coal ore during transportation. The rotating platform 81 is rotatably connected to the inner frame 3, so the swing top plate 83 does not hinder the horizontal movement of the coal ore during unloading.

[0036] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that variations may be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
