Description

Technical Field

[0001] This invention relates to the technical field of coal mines, and in particular to an antifreeze spraying device for coal transport vehicle compartments. Background Technology

[0002] As one of the main energy sources, coal often needs to be transported over long distances. During the winter transportation of coal, antifreeze needs to be sprayed on the inner walls of the transport vehicle to prevent the coal from freezing to the inner walls of the vehicle and becoming difficult to separate.

[0003] Traditional sprinkler systems are directly suspended above the vehicle's travel path, using a single sprinkler pipe perpendicular to the vehicle's path to spray the interior of the vehicle. This not only results in poor spray uniformity but also increases the risk of vehicles colliding with the sprinkler system. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the present invention provides an antifreeze spraying device for coal transport vehicle compartments that is beneficial for protecting equipment and improving the uniformity of antifreeze spraying.

[0005] The present invention provides an antifreeze spraying device for the cargo compartment of a coal transport vehicle, comprising:

[0011] A first lifting device is provided on the crossbeam, which is used to drive the top plate to rise and fall.

[0012] Furthermore, the first lifting device includes two sets of lead screws rotatably mounted on the crossbeam and a motor fixedly mounted on the crossbeam. The two sets of lead screws are coaxially connected and the threads of the two sets of lead screws rotate in opposite directions. Each set of lead screws is screwed with a lead screw nut, and each set of lead screw nuts is rotatably provided with a second connecting rod. Both sets of second connecting rods are rotatably connected to the top plate. The motor is used to drive the two sets of lead screws to rotate synchronously.

[0013] Furthermore, a collar is provided on the crossbeam, and the collar is coaxially rotatably sleeved on the support column. A guide post is provided on the outer circumferential wall of the collar.

A limit plate is provided on the support column. The first spring is located between the limit plate and the lifting plate. An arc-shaped plate is provided on the lifting plate. The axis of the arc-shaped plate is collinear with the axis of the support column. An arc-shaped guide groove is provided on the arc-shaped plate. The guide post is slidably installed inside the arc-shaped guide groove.

[0014] The support column is equipped with a second lifting device for driving the arc plate and lifting plate to overcome the elastic force of the first spring and move up and down along the axis of the support column.

[0015] Furthermore, the second lifting device includes a first support plate that is coaxially slidably sleeved on the support column and a second support plate that is coaxially rotatably sleeved on the support column.

[0021] Furthermore, a protective shell is provided on the outside of the rotating device, and the protective shell is fixedly installed on the support column.

[0022] Compared with the prior art, the beneficial effects of the present invention are as follows: In the initial state, the crossbeam is parallel to the carriage, and the horizontal spray pipe and the two sets of vertical spray pipes are all in contact with the crossbeam. When it is necessary to spray antifreeze on the empty transport vehicle carriage, the rotating device is activated to rotate the crossbeam along the axis of the support column to be located above the carriage and perpendicular to the carriage. Then, the folding device is activated to rotate the two sets of vertical spray pipes so that the spray nozzles of the two sets of vertical spray pipes are vertically aligned with the inner wall of the carriage. At the same time, the horizontal spray pipe is lowered to the bottom of the carriage so that the spray nozzles of the horizontal spray pipe are vertically aligned with the bottom of the carriage. Then, the external liquid supply pump is activated so that the two sets of vertical spray pipes and the horizontal spray pipes spray antifreeze on the inner wall and bottom of the carriage respectively. At the same time, the vehicle is moved so that the antifreeze is evenly sprayed on the inner wall of the carriage. Through the above settings, the situation where the spraying device is suspended above the vehicle transport route and is easily scratched by the vehicle is reduced, which is beneficial to protect the equipment and improves the uniformity of antifreeze spraying.

[0032] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0033] In the description of this invention, it should be noted that the orientations or positional relationships indicated by terms such as "center", "up", "down", "left", "right", "vertical", "horizontal", "inner", and "outer" are based on the orientations or positional relationships shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0034] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances. This embodiment is written in a progressive manner.

[0035] like Figures 1 to 2 As shown, the present invention provides an antifreeze spraying device for a coal transport vehicle compartment, comprising:

[0036] A support column 1 is provided, a crossbeam 2 is rotatably mounted on the support column 1, a rotating device 3 is provided on the support column 1, the rotating device 3 is used to drive the crossbeam 2 to rotate along the axis of the support column 1, and a folding device 4 is provided on the crossbeam 2.

[0037] A horizontal spray pipe 5 and two sets of vertical spray pipes 6 are mounted on a folding device 4. The folding device 4 is used to drive the horizontal spray pipe 5 to rise and fall relative to the crossbeam 2. At the same time, the folding device 4 is used to drive the two sets of vertical spray pipes 6 to rotate 90° relative to the crossbeam 2. The input ends of the horizontal spray pipe 5 and the vertical spray pipes 6 are both connected to the output end of an external liquid supply pump.

[0038] Among them, the axis of the horizontal spray pipe 5 is parallel to the crossbeam 2. When the horizontal spray pipe 5 is at its highest position, it is parallel to both sets of vertical spray pipes 6. When the horizontal spray pipe 5 is at its lowest position, it is perpendicular to both sets of vertical spray pipes 6.

[0039] In this embodiment, in the initial state, the crossbeam 2 is parallel to the carriage, and the horizontal spray pipe 5 and the two sets of vertical spray pipes 6 are all in contact with the crossbeam 2. When it is necessary to spray antifreeze on the empty transport vehicle carriage, the rotating device 3 is activated to rotate the crossbeam 2 along the axis of the support column 1 to be located above the carriage and perpendicular to the carriage. Then, the folding device 4 is activated to rotate the two sets of vertical spray pipes 6 so that the spray nozzles of the two sets of vertical spray pipes 6 are vertically aligned with the inner wall of the carriage. At the same time, the horizontal spray pipe 5 is lowered to the bottom of the carriage so that the spray nozzles of the horizontal spray pipe 5 are vertically aligned with the bottom of the carriage. Then, the external liquid supply pump is activated so that the two sets of vertical spray pipes 6 and the horizontal spray pipe 5 spray antifreeze on the inner wall and bottom of the carriage respectively. At the same time, the vehicle is moved so that the antifreeze is evenly sprayed on the inner wall of the carriage. Through the above settings, the situation where the spraying device is suspended above the vehicle transport route and is easily scratched by the vehicle is reduced, which is beneficial to protect the equipment and improves the uniformity of antifreeze spraying.

[0040] As a preferred embodiment of the above technical solution, such as Figures 3 to 4As shown, the folding device 4 includes two sets of first connecting rods 8 and a top plate 11. Two sets of connecting seats 7 are symmetrically arranged on the crossbeam 2. The two sets of first connecting rods 8 are rotatably connected to the two sets of connecting seats 7 respectively. L-shaped connecting rods 9 are arranged on the first connecting rods 8. A strip groove 10 is arranged on the crossbeam 2 for the L-shaped connecting rods 9 to move through. Two sets of vertical spray pipes 6 are fixedly installed on the two sets of L-shaped connecting rods 9 respectively.

[0041] Two sets of hangers 12 are vertically installed on the top plate 11. The two sets of hangers 12 extend vertically through the crossbeam 2 and into the lower part of the crossbeam 2. The two sets of hangers 12 are horizontally installed with mounting plates 13 at the ends of the two sets of hangers 12 that extend into the lower part of the crossbeam 2. The mounting plates 13 are used to fix and install the horizontal spray pipes 5. Two sets of straight guide grooves 14 are provided through the top plate 11. Sliding sliders 15 are slidably installed on the two sets of straight guide grooves 14. The two sets of sliding sliders 15 are rotatably connected to the two sets of first connecting rods 8 respectively.

[0042] A first lifting device is provided on the crossbeam 2, which is used to drive the top plate 11 to lift.

[0043] In this embodiment, by activating the first lifting device, the top plate 11 is lowered. During the descent of the top plate 11, under the connecting action of the first connecting rod 8, the two sets of sliders 15 are brought closer to each other, while the first connecting rod 8 is rotated along the connection point between the first connecting rod 8 and the connecting seat 7, until the L-shaped connecting rod 9 drives the vertical spray pipe 6 to rotate until the vertical spray pipe 6 is perpendicular to the crossbeam 2. At this time, the horizontal spray pipe 5 is lowered to the bottom of the carriage with the hanging rod 12, which makes it easy to fold and store the horizontal spray pipe 5 and the two sets of vertical spray pipes 6.

[0044] As a preferred embodiment of the above technical solution, such as Figure 3 As shown, the first lifting device includes two sets of lead screws 16 rotatably mounted on the crossbeam 2 and a motor 19 fixedly mounted on the crossbeam 2. The two sets of lead screws 16 are coaxially connected and the threads of the two sets of lead screws 16 are opposite. Each set of lead screws 16 is screwed with a lead screw nut 17. Each set of lead screw nuts 17 is rotatably provided with a second connecting rod 18. Both sets of second connecting rods 18 are rotatably connected to the top plate 11. The motor 19 is used to drive the two sets of lead screws 16 to rotate synchronously.

[0045] In this embodiment, by starting the motor 19, the motor 19 drives the two sets of lead screws 16 to rotate synchronously along their own axes, thereby causing the two sets of lead screw nuts 17 to move closer or further apart. While the two sets of lead screw nuts 17 are moving relative to each other, the two sets of second connecting rods 18 drive the top plate 11 to rise and fall, which facilitates the control of the rise and fall of the top plate 11.

[0046] As a preferred embodiment of the above technical solution, such as Figures 3 to 6As shown, a collar 20 is provided on the crossbeam 2. The collar 20 is coaxially rotatably sleeved on the support column 1. A guide column 21 is provided on the outer circumference of the collar 20.

The axis of the arc plate 25 is collinear with the axis of the support column 1. An arc guide groove 26 is provided on the arc plate 25. The guide column 21 is slidably installed inside the arc guide groove 26.

[0047] A second lifting device is provided on the support column 1 to drive the arc plate 25 and the lifting plate 23 to overcome the elastic force of the first spring 24 and move up and down along the axis of the support column 1;

[0048] In this embodiment, when it is necessary to rotate the crossbeam 2, the second lifting device is activated, causing the second lifting device to drive the arc plate 25 to overcome the elastic force of the first spring 24, raising the arc plate 25. Under the guidance of the arc guide groove 26 and the guide column 21, the crossbeam 2 rotates along the axis of the support column 1 until the crossbeam 2 is above the carriage. In the initial state, the arc plate 25 is pressed downward under the elastic force of the first spring 24, causing the arc plate 25 to slide downward relative to the support column 1. Under the guidance of the arc guide groove 26 and the guide column 21, the crossbeam 2 is parallel to the direction of carriage movement. Through the above arrangement, the crossbeam 2 will not affect the operation of the vehicle during idle time.

[0049] As a preferred embodiment of the above technical solution, such as Figures 5 to 7 As shown, the second lifting device includes a first support plate 27 coaxially slidably sleeved on the support column 1 and a second support plate 30 coaxially rotatably sleeved on the support column 1. The first support plate 27 is fixedly connected to the arc plate 25. A slot 28 is provided on the first support plate 27. A guide bar 29 is provided on the outer circumference of the support column 1. The guide bar 29 is parallel to the axis of the support column 1. The slot 28 is slidably locked on the guide bar 29.

[0050] A number of support rods 31 are arranged in a circular array between the second support plate 30 and the first support plate 27. The support rods 31 are all connected to the second support plate 30 and the first support plate 27 through universal joints. An adjustment device 32 is provided on the second support plate 30. The adjustment device 32 is used to manually drive the second support plate 30 to rotate along the axis of the support column 1.

[0051] In this embodiment, by rotating the second support plate 30, under the connected action of several sets of support rods 31, the several sets of support rods 31 drive the first support plate 27 to rise or fall along the axis of the support column 1, thereby facilitating the control of the raising and lowering of the arc plate 25.

[0052] As a preferred embodiment of the above technical solution, such as Figure 1 and Figure 8 As shown, the adjustment device 32 includes an operating lever 35 and a second spring 37. Two sets of pin holes 39 are provided on the outer circumference of the support column 1. The centers of the two sets of pin holes 39 are located on the same horizontal plane. A wing plate 33 is vertically provided on the second support plate 30. A through hole is provided through the wing plate 33. A limiting tube 34 coaxial with the through hole is provided on the outer wall of the wing plate 33.

[0053] The operating lever 35 moves through the limiting tube 34 and the through hole. A baffle 36 is provided on the operating lever 35. The second spring 37 is sleeved on the operating lever 35 and the limiting tube 34, and the two ends of the second spring 37 are fixedly connected to the wing plate 33 and the baffle 36 respectively.

[0054] A pin 38 is provided at one end of the operating lever 35 near the support column 1. The pin 38 is used to be inserted into the two sets of pin holes 39 in sequence.

[0055] In this embodiment, the above-mentioned settings facilitate the positioning of the second support plate 30, reduce the rotation of the second support plate 30 during the spraying process, and improve the operational stability of the equipment.

[0056] As a preferred embodiment of the above technical solution, such as Figures 1 to 2 As shown, the support column 1 is vertically fixed to the ground by pre-embedded anchor plates;

[0057] In this embodiment, the above-mentioned arrangement is beneficial to the installation stability of the support column 1.

[0058] As a preferred embodiment of the above technical solution, the rotating device 3 is provided with a protective shell, which is fixedly installed on the support column 1.

[0059] The present invention relates to an antifreeze spraying device for a coal transport vehicle compartment. Its installation method, connection method, or setting method are all common mechanical methods, and any method that can achieve its beneficial effect can be implemented.

[0060] The above are merely preferred embodiments of the present invention. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
