Description

Technical Field

[0001] The invention relates to the technical field of geological exploration, and in particular to a coalfield exploration and transportation device. Background Art

[0002] In the process of coalfield geological exploration, the collection and transportation of samples are very important links. These samples are of great significance for the study of geological structure, mineral resources, environmental impact assessment, etc. In order to ensure the safety of these samples during transportation, sample transport boxes are usually required.

[0003] The existing technology has the following problems: when the sample transport box is in use, rock samples are usually loaded directly into the transport box by hand, but rock samples have different sizes and weights, which will cause uneven weight distribution on both sides of the transport box, and then cause uneven force on both sides of the shoulders of the personnel when carrying the transport box, resulting in insufficient labor comfort for the personnel, and the uneven weight distribution will also cause the center of gravity of the personnel to change, increasing the probability of falling during transportation, resulting in transportation safety and stability not being ideal, and the transport box has a simple structure, and the overall weight is large after loading the rock samples, which makes the labor intensity of personnel transportation also large, which is not conducive to long-term transportation operations, and requires frequent changes of personnel to carry or rest, and the transportation efficiency is low. When the transport box is carried on the back, the personnel need to manually lift or lower the transport box, which further increases the transportation intensity, is time-consuming and labor-intensive to operate, and reduces the overall use effect of the device.

[0004] To this end, we proposed a coalfield exploration and transportation device to solve the above-mentioned drawbacks. Summary of the invention

[0013] Preferably, a sealing cover is rotatably connected to one side of the top of the transport box, a plurality of groups of partitions are installed inside the transport box, and a plurality of groups of air bags are installed on the surface of the partitions and on the inner wall of the transport box.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] (1) The present invention adopts an electric hydraulic rod and a pressure sensor. When transporting the products obtained from coalfield survey, the obtained items are directly placed in the transport box, and the pressure sensors are abutted on both sides of the bottom of the transport box. At this time, the transport box will apply pressure to the pressure sensor. After the items are placed inside, the pressure detected by the pressure sensors at different positions will be different. At this time, the relative expansion and contraction amounts of multiple groups of electric hydraulic rods around the transport box can be adjusted according to the changes in the differences, so that the transport box can rotate and tilt corresponding to the surface of the back plate, so that the center of gravity of the transport box returns to the middle position, avoiding excessive pressure on one side of the shoulder of the personnel to reduce comfort and avoiding one side being too heavy to cause the personnel to fall during transportation, thereby ensuring the safety of transportation and having the advantage of adjusting the center of gravity of the back load.

After the loading inside the transport box is completed, the operation of the brake motor can drive the driving gear to drive the adjusting rod, so that the adjusting rod can perform a corresponding lifting operation, and when the adjusting rod is lifted or lowered, the moving rod will also perform a corresponding telescopic operation, thereby realizing the lifting operation of the transport box, avoiding the need for personnel to manually lift the transport box to a high height for carrying, which can reduce the labor intensity of personnel, and during subsequent transportation, the weight of the transport box will also be largely dispersed to the moving rod and the adjusting rod, so that the actual weight acting on the shoulders of personnel is very small, which can not only improve the transportation efficiency, but also improve the safety of transportation. The comfort of personnel during transportation can be improved, and the labor intensity of personnel can be reduced. There is no need to frequently change the carrying personnel, which can improve the transportation efficiency. In addition, the lockable mobile wheels can assist personnel in moving during transportation, and the movement of personnel can be made smoother by rolling. The weight distribution and tire assistance are used to replace the traditional method of relying on manpower to carry the load alone, which can greatly reduce the difficulty of transportation and improve the use effect. When facing uneven roads, the telescopic operation of the first spring can also ensure that the height of the device will not change significantly, thereby reducing the difficulty of movement caused by uneven roads. It has the advantages of transportation auxiliary support and low operation intensity. BRIEF DESCRIPTION OF THE DRAWINGS

When the pressure difference is detected, the relative ejection operation of the electric hydraulic rod 6 can make the transport box 2 deflect to the side with smaller pressure, thereby realizing the center of gravity adjustment operation. When the transport box 2 is rotated and adjusted, the deformation ejection of the second spring 33 can make the pressure sensor 11 continue to contact the bottom of the transport box 2, so as to continue to detect the pressure value. When the pressure sensors 11 at different positions detect that the pressure difference is within the preset range, it means that the adjustment of the transport box 2 is completed, so as to readjust the center of gravity offset caused by the different weights, thereby avoiding excessive pressure on one side of the shoulder of the person causing a decrease in comfort and avoiding falling of the person during transportation due to excessive weight on one side, thereby ensuring the safety of transportation and improving the overall use effect of the device.

[0030] In this embodiment: fixed arms 14 are symmetrically welded at the middle position of the two side surfaces of the back plate 1, a connecting arm 13 is rotatably connected to the top side position of the fixed arm 14, a handle 12 is installed at the top side position of the connecting arm 13, and a plurality of control buttons are installed on the surface of the handle 12, a receiving seat 16 is welded at the bottom side position of the fixed arm 14, and a moving rod 18 is slidably connected to the inner position of the receiving seat 16, and an adjusting seat 31 is symmetrically welded at both ends of the bottom of one side surface of the back plate 1, and an adjusting rod 28 is slidably connected to the inner position of the adjusting seat 31, and a plurality of groups of teeth 29 are welded at the middle position of the surface of the adjusting rod 28, one end of the teeth 29 is meshingly connected to a driving gear 30, and one end of the driving gear 30 is connected to the output end of the brake motor 25, and a fixing ring 24 is fixedly installed on the outer periphery of the brake motor 25, and the fixing ring 24 is welded to the bottom end of the back plate 1 through a bracket.

[0031] Specifically, by adjusting the adjustment rod 28 and the moving rod 18, the lockable moving wheels can contact the bottom surface, so that the two can support the entire structure, thereby greatly reducing the subsequent pressure and weight on the shoulders of the personnel, thereby dispersing the weight, thereby reducing the labor intensity of the personnel when carrying the load subsequently, and facilitating better transportation.

[0033] Specifically, the lockable universal wheel 21 is a common structure, which is used here to facilitate personnel to move the entire device, so it will not be described in detail.

[0034] In this embodiment, a plurality of positioning holes 19 are provided at the middle of the surface of the moving rod 18 and the middle of the surface of the adjusting rod 28 .

[0035] Specifically, the positioning hole 19 is provided to facilitate the connection and fixation of the fastening screw. In order to ensure that the fastening screw can be fastened smoothly, a corresponding thread can be provided inside the positioning hole 19 .

[0036] In this embodiment, fastening bolts 17 are installed on one side surface of the accommodating seat 16 and one side surface of the adjusting seat 31 , and the fastening bolts 17 are threadedly connected to the positioning holes 19 .

[0037] Specifically, the fastening bolts 17 are provided to facilitate fixing the adjusting rod 28 and the moving rod 18 after adjustment, so as to ensure the stability of use during subsequent transportation.

[0038] In this embodiment: a back pad 3 is laid on the other side of the backboard 1 , and shoulder straps 8 are symmetrically installed on both sides of the back pad 3 and located on the surface of the backboard 1 .

[0039] Specifically, the back pad 3 is provided to provide a buffering effect between the back of the person and the backboard 1, thereby improving the comfort of the person during back-carrying transportation, while the shoulder strap 8 is provided to facilitate the person to carry the transport box 2 on his back for subsequent mobile transportation.

[0040] In this embodiment: a control box 26 is installed in the middle of the bottom of the back plate 1, and a battery and a controller are installed inside the control box 26. The battery, brake motor 25, pressure sensor 11, electric hydraulic rod 6 and control button are all electrically connected to the controller through wires.

[0041] Specifically, the battery, brake motor 25, pressure sensor 11, electric hydraulic rod 6 and control button are all common devices, and any model can be easily purchased on the market, and the application technology is mature, so no further elaboration is made.

[0042] In this embodiment: a sealing cover 4 is rotatably connected to one side of the top of the transport box 2, a plurality of partitions 9 are installed inside the transport box 2, and a plurality of air bags 10 are installed on the surface of the partitions 9 and on the inner wall of the transport box 2.

[0043] Specifically, the transport box 2 is provided to store various coals and rocks collected during coalfield surveys, so as to facilitate subsequent transportation to the laboratory for analysis and processing, and the partition 9 is provided to divide the space inside the transport box 2 so that the stored items have no space to move left and right, thereby avoiding damage due to left and right movement and collision during subsequent transportation, thereby ensuring the integrity of the collected items. At the same time, the airbag 10 provided can alleviate the impact of collisions, and in order to ensure that the airbag 10 will not be punctured, a rubber pad or other protective items can be wrapped on the surface of the airbag 10, which will not be elaborated here.

[0044] In this embodiment: the control circuit of the control box 26 can be realized by simple programming by those skilled in the art, which is common knowledge in the art. It is only used without modification, so the control method and circuit connection will not be described in detail.

[0045] Working principle: During operation, personnel can directly put the coal or rock collected in coalfield exploration into the transport box 2, and use the transport box 2 to store and transfer the objects to be tested, so as to facilitate subsequent testing in the laboratory, so as to determine the content of the coalfield and facilitate subsequent mining operations. Since a partition 9 is provided inside the transport box 2 and an air bag 10 is provided on the surface of the partition 9, the coal or rock can be wrapped by the coordinated use of the partition 9 and the air bag 10, thereby avoiding direct collision with the surface of the transport box 2 to cause damage, thereby ensuring the integrity of the structure. After the survey and collection is completed, the operation of the brake motor 25 can drive the drive gear 30 connected to its output end to rotate, and the rotation of the drive gear 30 can be controlled by the brake motor 25. The teeth 29 that mesh with each other are used to move the adjusting rod 28, so that the adjusting rod 28 can lift the entire back plate 1, thereby facilitating personnel to carry the transport box 2, and there is no need to manually lift the transport box 2, which reduces the labor intensity of personnel, and when the adjusting rod 28 is lifted, the moving rod 18 inside the accommodating seat 16 will also be synchronously extended and retracted, so as to improve the stability during height adjustment and avoid the tilting and falling of the transport box 2 caused by unilateral lifting. Then, after the height change of the adjusting rod 28 and the moving rod 18 is completed, the fastening operation of the adjusting rod 28 and the moving rod 18 can be achieved by connecting the fastening bolts 17 with the positioning holes 19, so as to avoid changes during subsequent transportation and movement, and ensure the use of the structure. The stability of the personnel can then directly carry the entire structure to the back position through the shoulder straps 8, and because the adjustment rod 28 and the moving rod 18 will contact the ground through the lockable moving wheels at the bottom of themselves, the weight of the transport box 2 can be dispersed, so that the actual weight carried by the personnel is very small, and it only plays a role in controlling the moving direction. In this way, the pressure on the personnel during transportation can be effectively reduced, and the labor intensity of the personnel can be reduced simultaneously. There is no need to frequently replace personnel during transportation, thereby ensuring the efficiency of transportation. Moreover, after the loading is completed, due to the different weights of the objects stored in the transport box 2, the weights at different positions inside the transport box 2 will also be different. At this time, multiple groups of objects in contact with the bottom of the transport box 2 can be The pressure sensor 11 can detect the difference in pressure on both sides of the bottom of the transport box 2, and then the transport box 2 can be rotated and adjusted by operating the relative telescopic operation of multiple groups of electric hydraulic rods 6 connected around the transport box 2, so that the inclination angle of the transport box 2 changes, and the center of gravity of the transport box 2 returns to the middle position, thereby avoiding excessive pressure on one side of the shoulder of the personnel causing a decrease in comfort and avoiding falls caused by excessive weight on one side during transportation, thereby ensuring the safety of transportation. Then the personnel can move the transport box 2 through their own movement, thereby achieving the purpose of transporting the products obtained from the coalfield survey, facilitating subsequent detection and analysis, and the device as a whole has the advantages of auxiliary transportation support, back-load center of gravity adjustment, and low operation intensity.
