Description

Technical Field

[0001] The utility model relates to the technical field of ore car compartments, in particular to a dust-reducing ore car compartment. Background Technique

[0002] After the ore is mined, it needs to be transported to the processing site by an ore transport vehicle. When the ore transport vehicle travels at high speed on the road, the dust on the ore will inevitably be blown up, resulting in environmental pollution or dirtying the vehicles behind. Therefore, during the process of transporting the ore, the ore transport vehicle usually covers the top of the carriage with a tarpaulin, thereby avoiding the dust on the ore pile from being blown up by the wind;

[0003] However, in the actual transportation process, there is no limiting structure between the side edge of the tarpaulin and the side of the carriage. During the high-speed driving of the ore transport vehicle, the strong airflow is likely to blow up the side of the tarpaulin to generate a gap, and the dust is blown up through the gap. In order to avoid this situation, a dust-reducing ore car compartment is provided. Content of the Utility Model

[0004] The purpose of the utility model is to provide a dust-reducing ore car compartment in order to solve the problems in the above background.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A dust-reducing ore car compartment, including a carriage main body and a dust-reducing component arranged outside the carriage main body. The dust-reducing component includes a fixed shaft, an n-shaped turning arm, and a tarpaulin. The tarpaulin covers the top of the carriage main body for dust-reducing shielding of the top of the carriage main body. One end of the tarpaulin is fixedly connected to one end of the top of the carriage main body. The fixed shaft is symmetrically fixed to the two sides of the bottom of the carriage main body. The two vertical parts of the n-shaped turning arm are respectively rotatably connected to the outside of the fixed shaft, and the horizontal part at the top of the n-shaped turning arm is adhesively fixed to the other end of the tarpaulin. The turning of the n-shaped turning arm is used to drive the storage and unfolding of the tarpaulin. Pressing components are also arranged on both sides of the outer wall of the carriage main body, and the pressing components are used for pressing the two side edges of the tarpaulin;

[0006] The pressing component includes a bearing base, an n-shaped pressing arm, a rotating shaft, a winding wheel, a second guide wheel, a linkage steel wire rope, and a torsion spring;

[0007] The bearing bases are symmetrically fixed to both ends of the side of the outer wall of the carriage main body. The n-shaped pressing arm is rotatably connected to the two bearing bases through the rotating shaft. When the n-shaped pressing arm turns upwards, it is used to press the side edge of the tarpaulin, and when the n-shaped pressing arm turns downwards, the pressing on the tarpaulin is released;

[0008] One rotating shaft penetrates through the bearing base and is fixedly connected to the winding wheel. The torsion springs are distributed between the winding wheel and the bearing base and are sleeved on the outside of the rotating shaft. The two ends of the torsion spring are respectively connected to the outer walls of the bearing base and the winding wheel;

[0009] The second guide wheel is rotatably installed on the side of the carriage body and close to the bottom position of the carriage body. One end of the linkage steel wire rope is tied and fixed inside the winding wheel, and the other end of the linkage steel wire rope passes through the lower part inside the second guide wheel and extends upward to be tied and connected to the n-shaped flipping arm;

[0010] The flipped n-shaped flipping arm pulls the linkage steel wire rope to drive the winding wheel to rotate, which is used to provide power for the downward flipping of the n-shaped edge pressing arm. The rotation of the winding wheel forms a torsional deformation of the torsion spring, which is used to provide an upward flipping and resetting power for the downward flipped n-shaped edge pressing arm.

[0011] As a further scheme of the present utility model: the horizontal cross-section of the horizontal part of the n-shaped edge pressing arm is in a "Z" - shaped structure. When the n-shaped edge pressing arm faces upward, half of its part is in a state of being away from the carriage body, which is used to provide space for the flipping of the n-shaped flipping arm.

[0012] As a further scheme of the present utility model: two second guide wheels are provided and are distributed in parallel along the horizontal direction, and one of the second guide wheels is aligned with the winding wheel in the vertical direction.

[0013] As a further scheme of the present utility model: the dust reduction assembly further includes a hanging ring, a first guide wheel, a winch, and a winding steel wire rope;

[0014] The winch is fixed to the top of the front end of the carriage body. The first guide wheel is installed at the front end of the carriage body and is distributed below the winch. The hanging ring is fixed to the upper surface of the tarpaulin;

[0015] One end of the winding steel wire rope is tied and connected to the horizontal part at the top of the n-shaped flipping arm. One end of the winding steel wire rope sequentially passes through the inside of the hanging ring and the inside of the winch and extends to be tied to the outside of the winding shaft of the first guide wheel. By operating the winch, the winding and unwinding of the winding steel wire rope are realized, so as to realize the contraction and unfolding of the tarpaulin.

[0016] As a further scheme of the present utility model: the dust reduction assembly further includes a fixed column and a tension spring;

[0017] The fixed column is fixed to the side of the carriage body and close to the bottom of the carriage body. The two ends of the tension spring are respectively connected to the fixed column and the n-shaped flipping arm. When the n-shaped flipping arm flips and approaches the front end of the carriage body, the tension spring is stretched. The stretched tension spring is used to provide a pulling force for the flipping of the n-shaped flipping arm.

[0018] Compared with the prior art, the beneficial effects of the present utility model are:

[0019] By setting the edge pressing component, the side limiting and pressing operation of the tarpaulin can be realized, thus effectively avoiding the situation that the side of the tarpaulin is blown up to generate gaps, resulting in the outward scattering of ore dust.

Detailed Embodiment

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0026] Please refer to Figures 1 to 4, in the embodiment of the present utility model, a dust - reducing ore car cargo box includes a carriage main body 1 and a dust - reducing component 2 arranged outside the carriage main body 1. The dust - reducing component 2 includes a fixed shaft 201, an n - shaped turning arm 202, and a tarpaulin 205. The tarpaulin 205 covers the top of the carriage main body 1 and is used for dust - reducing and shielding the top of the carriage main body 1. One end of the tarpaulin 205 is fixedly connected to one end of the top of the carriage main body 1. The fixed shaft 201 is symmetrically fixed to the bottom sides of both sides of the carriage main body 1. The two vertical parts of the n - shaped turning arm 202 are respectively rotatably connected to the outside of the fixed shaft 201, and the horizontal part at the top of the n - shaped turning arm 202 is adhesively fixed to the other end of the tarpaulin 205. The turning of the n - shaped turning arm 202 is used to drive the storage and unfolding of the tarpaulin 205. Pressing components 3 are also arranged on both sides of the outer wall of the carriage main body 1, and the pressing components 3 are used for pressing the two side edges of the tarpaulin 205;

[0027] The pressing component 3 includes a bearing base 301, an n - shaped pressing arm 302, a rotating shaft 303, a winding wheel 304, a second guide wheel 305, a linkage steel wire rope 306, and a torsion spring 307;

[0028] The bearing bases 301 are symmetrically fixed to the two ends of the side surface of the outer wall of the carriage main body 1. The n - shaped pressing arm 302 is rotatably connected to the two bearing bases 301 through the rotating shaft 303. When the n - shaped pressing arm 302 turns upwards, it is used to press the side edge of the tarpaulin 205, and when the n - shaped pressing arm 302 turns downwards, the pressing on the tarpaulin 205 is released;

[0029] One rotating shaft 303 penetrates through the bearing base 301 and is fixedly connected to the winding wheel 304. The torsion spring 307 is distributed between the winding wheel 304 and the bearing base 301 and is sleeved on the outside of the rotating shaft 303. The two ends of the torsion spring 307 are respectively connected to the outer walls of the bearing base 301 and the winding wheel 304;

[0030] The second guide wheel 305 is rotatably installed on the side of the carriage main body 1 and close to the bottom position of the carriage main body 1. One end of the linkage steel wire rope 306 is bundled and fixed to the inside of the winding wheel 304. The other end of the linkage steel wire rope 306 passes through the lower part inside the second guide wheel 305 and extends upwards to be bundled and connected to the n - shaped turning arm 202;

[0031] The turned n - shaped turning arm 202 pulls the linkage steel wire rope 306 to drive the winding wheel 304 to rotate, which is used to provide power for the downward turning of the n - shaped pressing arm 302. The rotation of the winding wheel 304 causes a torsional deformation of the torsion spring 307, which is used to provide upward turning and reset power for the downward - turned n - shaped pressing arm 302;

[0032] The dust - reducing component 2 further includes a lifting ring 206, a first guide wheel 207, a winch 208, and a winding steel wire rope 209;

[0033] The winch 208 is fixed to the top of the front end of the carriage main body 1. The first guide pulley 207 is installed at the front end of the carriage main body 1 and is distributed below the winch 208. The hanging ring 206 is fixed to the upper surface of the tarpaulin 205.

[0034] One end of the winding steel wire rope 209 is bundled and connected to the horizontal part at the top of the n-shaped turning arm 202. One end of the winding steel wire rope 209 passes through the inside of the hanging ring 206 and the inside of the winch 208 in sequence and extends to be bundled outside the winding shaft of the first guide pulley 207. By operating the winch 208, the winding and unwinding of the winding steel wire rope 209 are realized, so as to realize the contraction and unfolding of the tarpaulin 205.

[0035] The dust reduction assembly 2 further includes a fixed column 203 and a tension spring 204.

[0036] The fixed column 203 is fixed to the side of the carriage main body 1 and close to the bottom of the carriage main body 1. Both ends of the tension spring 204 are respectively connected to the fixed column 203 and the n-shaped turning arm 202. When the n-shaped turning arm 202 turns close to the front end of the carriage main body 1, the tension spring 204 is stretched. The stretched tension spring 204 is used to provide tension for the turning of the n-shaped turning arm 202.

[0037] In this embodiment, it should be supplemented and explained that when the carriage main body 1 is in use, it is installed on the vehicle chassis of the engineering transport vehicle. The connection structure between the carriage main body 1 and the vehicle chassis of the engineering transport vehicle is a prior art structure, so it will not be elaborated herein.

[0038] When the carriage main body 1 is loading materials, its winch 208 winds the winding steel wire rope 209. At this time, the n-shaped turning arm 202 turns towards the front end of the carriage main body 1 (that is, towards the winch 208. The discharge port of the carriage main body 1 is at the rear end). The tension spring 204 and the linkage steel wire rope 306 are both in a stretched state. The tarpaulin 205 is in a contracted state and the n-shaped edge pressing arm 302 is in a downward state. At this time, the top of the carriage main body 1 is open and unobstructed, and ore loading operations can be carried out.

[0039] After the ore loading is completed, the winch 208 can be started to unwind the winding steel wire rope 209. At this time, the n-shaped turning arm 202 turns towards the rear end of the carriage main body 1 under the elastic force of the tension spring 204. The n-shaped turning arm 202 pulls the winding steel wire rope 209 and the tarpaulin 205, and the tarpaulin 205 unfolds and covers the top of the carriage main body 1.

[0040] Meanwhile, as the n-type flipping arm 202 flips, the pulling force of the n-type flipping arm 202 on the linkage steel wire rope 306 is gradually released. At this time, the winding wheel 304 rotates under the torque of the torsion spring 307 and winds the linkage steel wire rope 306. The rotating winding wheel 304 drives the n-type edge pressing arm 302 to flip upward through the rotating shaft 303. Finally, the n-type edge pressing arm 302 flips to a state where it is vertically upward. At this time, the part of the n-type edge pressing arm 302 close to the front end of the carriage body 1 fits against the side of the tarpaulin 205, making the side of the front end of the tarpaulin 205 closely fit against the side of the carriage body 1. The side of the rear end of the tarpaulin 205 (i.e., the position close to the carriage body 1) remains in contact with the side of the carriage body 1 under the self-weight pressure of the n-type flipping arm 202;

[0041] Through the cooperation of the above-mentioned multiple parts, the side limiting and pressing operation of the tarpaulin 205 can be realized, effectively avoiding the situation that the side of the tarpaulin 205 is blown up to generate gaps, resulting in the outward dispersion of ore dust.

[0042] Please refer specifically to Figures 1 to 4 , the top view cross-section of the horizontal part of the n-type edge pressing arm 302 is in a "Z" - shaped structure. When the n-type edge pressing arm 302 is in the upward and facing state, half of the part is in a state of being away from the carriage body 1, providing space for the flipping of the n-type flipping arm 202.

[0043] In this embodiment: through this structure, when the n-type edge pressing arm 302 flips upward, the part of the n-type edge pressing arm 302 close to the front end of the carriage body 1 fits and presses against the side of the tarpaulin 205, while the part of the n-type edge pressing arm 302 close to the rear end of the carriage body 1 has a gap space with the carriage body 1;

[0044] When the n-type edge pressing arm 302 flips downward, the part of the n-type edge pressing arm 302 close to the front end of the carriage body 1 has a gap space with the carriage body 1, while the part of the n-type edge pressing arm 302 close to the rear end of the carriage body 1 is in a state of being close to the carriage body 1;

[0045] The gap space between the n-type edge pressing arm 302 and the carriage body 1 in the two states can provide space for the flipping of the n-type flipping arm 202, so that the flipping of the n-type edge pressing arm 302 and the n-type flipping arm 202 will not interfere with each other or collide.

[0046] Please refer specifically to Figures 1 to 4 , there are two second guide wheels 305 and they are distributed in parallel along the horizontal direction. One second guide wheel 305 is aligned with the winding wheel 304 in the vertical direction.

[0047] In this embodiment: the second guide wheel 305 can provide guidance and limit for the direction change of the linkage steel wire rope 306.

[0048] The above are only the preferred specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent substitutions or changes, and should be covered within the protection scope of the present utility model.
