Description

Technical Field

[0001] The present invention belongs to the technical field of hazardous chemical tanker cleaning, and in particular relates to a spray cleaning mechanism and cleaning equipment for hazardous chemical tanker cleaning. Background Art

[0002] Hazardous chemical tank trucks, also known as hazardous chemical transport trucks, refer to special high-risk vehicles used to load and unload explosive, flammable, poisonous, corrosive, radioactive and other substances.

[0003] Hazardous chemicals tank trucks generally include tanks for storing and transporting hazardous chemicals. During long-term use, the hazardous chemicals carried in the tanks will inevitably produce sediments and debris, which will corrode and clog the tanks and reduce the internal volume of the tanks, resulting in inaccurate calculation and measurement data, and causing the quality of the hazardous chemicals in the tanks to decline.

[0004] This requires cleaning the inner wall of the tank, and the existing cleaning method usually adopts manual cleaning, which is labor-intensive, time-consuming and labor-intensive, and the toxic gas that is not completely discharged in the tank can easily cause serious harm to the health of the operators.

[0005] A Chinese invention patent (publication number: CN117463728A) discloses an oil tank cleaning device and an engineering vehicle, wherein the spray cleaning mechanism is composed of a first drive, a first faucet, a second drive and a second faucet, wherein the first faucet and the second faucet are both L-shaped, and their water outlet ends are perpendicular to each other. When in use, the first drive drives the first faucet to rotate, and the second drive drives the second faucet to rotate, thereby changing the outlet direction of the cleaning liquid to clean the inside of the tank.

[0006] However, in actual use, due to structural limitations, the flushable range of the final water outlet is still small and the cleaning effect is poor. Summary of the invention

[0007] The purpose of the present invention is to provide a spray washing mechanism and cleaning equipment for cleaning hazardous chemical tank trucks, so as to solve the problems of small cleaning range and poor cleaning effect caused by structural defects of existing spray washing mechanisms.

[0008] In order to achieve the above technical objectives, the technical solution adopted by the present invention is as follows:

[0009] A spray washing mechanism for washing a hazardous chemical tanker, comprising:

[0010] A main body installed on the bracket and connected to the pipeline, wherein the main body is provided with a connecting hole near one end of the pipeline, and a secondary hole is radially provided on the main body, and the secondary hole is connected to the pipeline through the connecting hole;

[0011] A moving part, wherein the moving part is sleeved on the main body, and an accommodating groove is formed on the inner wall of the moving part, and the accommodating groove is communicated with the auxiliary hole;

[0012] A power element, the power element is used to drive the moving part to move relative to the main body along the axis direction of the main body;

[0013] A retaining frame, wherein the retaining frame is rotatably mounted on the main body, and the moving part is slidably connected to the retaining frame;

[0014] A rotating element, the rotating element is used to drive the retaining frame to rotate around the axis of the main body;

[0015] A limiting frame, wherein the limiting frame is fixedly mounted on the retaining frame;

[0016] A nozzle, the nozzle being rotatably mounted on a limiting frame;

[0017] A secondary pipe, the secondary pipe is installed between the nozzle and the moving part, and the nozzle is connected with the containing tank through the secondary pipe;

[0018] The transmission element is installed between the nozzle and the moving part, and is used to drive the nozzle to deflect when the power element drives the moving part to move relative to the main body, thereby changing the angle between the nozzle and the central axis of the main body.

[0019] It is further defined that a secondary part is provided between the moving part and the power element;

[0020] The auxiliary part is axially slidably mounted on the main body and is rotationally connected to the moving part;

[0021] The power element is installed on the bracket and connected with the auxiliary component.

[0022] Such a structural design completes the connection between the moving part and the power element through an auxiliary part. The auxiliary part is axially slidably installed on the main body and is rotationally connected to the moving part. This prevents the moving part from rotating around the axis of the main body under the action of the rotating element and acting in the opposite direction on the power element, thereby causing the axial position of the moving part on the main body to change. It is very practical.

[0023] It is further defined that the auxiliary component is annular and is connected to the main body via a spline.

[0024] Such a structural design completes the axial sliding installation between the auxiliary component and the main body through a spline connection, has a simple structure, is easy to install, and is highly practical.

[0025] It is further defined that the power element includes a return spring, a steel wire rope, a sleeve, and a winding mechanism rotatably mounted on an external support frame;

[0026] One end of the steel wire rope is connected to the auxiliary component, and the other end is wound on the winding mechanism;

[0027] The sleeve is sleeved on the wire rope, one end of the sleeve is fixedly mounted on the bracket, and the other end is fixedly mounted on the external support frame;

[0028] The winding mechanism is used for winding the wire rope;

[0029] The external support frame is provided with a locking mechanism for fixing the winding mechanism;

[0030] The return spring is located between the retaining frame and the moving part, and is used to drive the retaining frame to move in a direction away from the bracket relative to the main body.

[0031] This structural design, through the mutual cooperation of the wire rope, the sleeve and the winding mechanism rotatably installed on the external support frame, forms a mechanism similar to the brake line of a bicycle, and cooperates with the return spring to move the moving parts back and forth. The structure is simple and easy to use. At the same time, when in use, it is only necessary to fix the two ends of the sleeve respectively, and the brake line can be used normally. It does not cause interference to the movement of the spray cleaning mechanism relative to the external support frame, and is highly practical.

[0032] It is further defined that the return spring is a tension spring;

[0033] The moving part comprises a sub-frame, which is located at one end of the moving part close to the sub-frame and sleeved on the main body;

[0034] One end of the tension spring is connected to the auxiliary frame, and the other end is connected to the retaining frame;

[0035] The moving part is rotationally connected with the auxiliary part via the auxiliary frame.

[0036] Such a structural design, by using a tension spring as a return spring and cooperating with a sub-frame installed near one end of the sub-component, can reduce the obstruction of the front end of the spraying mechanism and increase the cleaning range of the cleaning mechanism on the basis of completing the purpose of driving the retaining frame to move away from the bracket relative to the main body, and is highly practical.

[0037] It is further defined that a connecting frame is fixedly installed between the bracket and the main body, and the connecting frame is in a hollow Z-shape;

[0038] One end of the connecting frame is connected to the main body, and the other end is connected to the pipeline;

[0039] A plurality of auxiliary ropes are evenly arranged at one end of the auxiliary component away from the retaining frame with the central axis of the main body as the center;

[0040] A connecting ring is fixedly installed at one end of the steel wire rope close to the auxiliary component. The connecting ring is located above the connecting frame and is fixedly connected to the free end of the auxiliary rope.

[0041] This structural design, through the Z-shaped connecting frame, cooperates with the auxiliary rope and the connecting ring, to avoid the wire rope, so as to prevent the bracket from being directly fixed on the main body, which would cause the pulling direction of the wire rope to be unable to coincide with the central axis of the main body, and thus cause the problem of unsmooth pulling of the moving parts. It is very practical.

[0042] It is further defined that the nozzles are multiple and are evenly arranged along the circumference of the axis of the main body.

[0043] Such a structural design, through the uniform circumferential arrangement of multiple nozzles, ensures that the center of gravity of the retaining frame, rotating element, limit frame and nozzle coincides with the axis of the main body when rotating, and the rotation is more stable and practical.

[0044] It is further defined that the rotating element is composed of a nozzle disposed obliquely relative to a horizontal plane;

[0045] There is a certain angle between the nozzle and the vertical plane where the central axis of the main body is located.

[0046] This structural design uses an inclined nozzle as a power source. When the nozzle sprays cleaning water / high-pressure steam, the reaction force of the cleaning water / high-pressure steam is used to drive the retaining frame to rotate through the limit frame. There is no need for an additional power source, which is more convenient to use.

[0047] It is further defined that the transmission element includes a gear and a rack meshing with each other;

[0048] The limiting frame is provided with an annular groove, the gear is rotatably mounted in the annular groove, and the nozzle is fixedly connected to the gear;

[0049] The rack is fixedly mounted on the moving part.

[0050] This structural design uses gears and racks to form transmission elements, so that when the power element drives the moving part to move relative to the main body, the nozzle is driven to deflect, thereby changing the angle between the nozzle and the central axis of the main body. It has a simple structure, is easy to install, and is highly practical.

[0051] The present invention also discloses a cleaning device, comprising an insertion mechanism and the above-mentioned spray cleaning mechanism for cleaning a hazardous chemical tanker; the insertion mechanism comprises a mounting arm, a bracket and an external support frame;

[0052] The bracket is fixedly mounted on the end of the mounting arm, and the mounting arm is used to drive the spray cleaning mechanism to extend into the interior of the tank body.

[0053] The invention adopting the above technical solution has the following advantages:

[0054] 1. The rotating element drives the holder to rotate, drives the nozzle installed on the holder to rotate, cooperates with the power element to drive the moving part to move along the axis direction of the main body, and drives the nozzle to deflect through the transmission element. Then, the rotation and deflection of the nozzle can be used to achieve multi-angle cleaning of the inside of the tank, with a wide cleaning range and better cleaning effect;

[0055] 2. Through the mutual cooperation of the steel wire rope, the sleeve and the winding mechanism rotatably mounted on the external support frame, a mechanism similar to the brake line of a bicycle is formed, and the moving parts are moved back and forth with the help of the reset spring. The structure is simple and easy to use. At the same time, when in use, only the two ends of the sleeve need to be fixed respectively, and the brake line can be used normally. The movement of the spray cleaning mechanism relative to the external support frame is not interfered, and the practicability is strong.

[0056] 3. The inclined nozzle is used as the power source. When the nozzle sprays cleaning water / high-pressure steam, the reaction force of the cleaning water / high-pressure steam is used to drive the retaining frame to rotate through the limit frame. No additional power source is required, which is more convenient to use.

[0057] 4. The transmission element is formed by gears and racks, so that when the power element drives the moving part to move relative to the main body, the nozzle is driven to deflect, thereby changing the angle between the nozzle and the central axis of the main body. The structure is simple, the installation is convenient, and the practicability is strong. BRIEF DESCRIPTION OF THE DRAWINGS

[0075] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that in the drawings or descriptions of the specification, similar or identical parts use the same figure numbers, and the implementation methods not shown or described in the drawings are forms known to ordinary technicians in the relevant technical field. In addition, the directional terms mentioned in the embodiments, such as "upper", "lower", "top", "bottom", "left", "right", "front", "back", etc., are only referenced to the directions of the drawings and are not used to limit the scope of protection of the present invention.

[0076] like Figures 1 to 8 As shown, a spray washing mechanism for washing a hazardous chemical tanker of the present invention comprises:

[0077] A main body 2 is mounted on the bracket 1 and connected to the pipeline 10. A connecting hole 21 is formed at one end of the main body 2 close to the pipeline 10. A secondary hole 22 is radially formed on the main body 2. The secondary hole 22 is connected to the pipeline 10 through the connecting hole 21.

[0078] The moving part 3 is sleeved on the main body 2, and the inner wall of the moving part 3 is provided with a receiving groove 30, which is communicated with the auxiliary hole 22;

[0079] A power element, which is used to drive the moving part 3 to move relative to the main body 2 along the axis direction of the main body 2;

[0080] A retaining frame 4, wherein the retaining frame 4 is rotatably mounted on the main body 2, and the moving part 3 is slidably connected to the retaining frame 4;

[0081] A rotating element, the rotating element is used to drive the retaining frame 4 to rotate around the axis of the main body 2;

[0082] The limiting frame 5 is fixedly mounted on the retaining frame 4;

[0083] The nozzle 6 is rotatably mounted on the limiting frame 5;

[0084] Auxiliary pipe, the auxiliary pipe is installed between the nozzle 6 and the moving part 3, and the nozzle 6 is connected with the containing groove 30 through the auxiliary pipe;

[0085] The transmission element is installed between the nozzle 6 and the moving part 3, and is used to drive the nozzle 6 to deflect when the power element drives the moving part 3 to move relative to the main body 2, thereby changing the angle between the nozzle 6 and the central axis of the main body 2.

[0086] like Figure 6 As shown, a first bearing 40 is installed between the main body 2 and the retaining frame 4.

[0087] In fact, according to actual conditions, a shaft sleeve can be set between the main body 2 and the retaining frame 4, or they can be directly sleeved on each other to achieve a rotational connection between the main body 2 and the retaining frame 4. This embodiment achieves a rotational connection between the main body 2 and the retaining frame 4 through a first bearing 40, and converts the sliding friction between the main body 2 and the retaining frame 4 into rolling friction, which can effectively reduce friction and has strong practicality.

[0088] like Figure 6 As shown, a sub-component 31 is provided between the moving part 3 and the power element;

[0089] The auxiliary part 31 is axially slidably mounted on the main body 2 and is rotationally connected to the moving part 3;

[0090] The power element is mounted on the bracket 1 and connected to the auxiliary component 31 .

[0091] In fact, according to actual conditions, it is also possible to select a method such as evenly opening a plurality of annular grooves on the outer wall of the moving part 3, and using a hydraulic cylinder to drive the rack to reciprocate, and then using the rack to mesh with the annular grooves. When the moving part 3 rotates, the axial position of the moving part 3 on the main body 2 can be controlled. In this embodiment, the connection between the moving part 3 and the power element is completed by the auxiliary part 31. The auxiliary part 31 is axially slidably installed on the main body 2 and is rotatably connected to the moving part 3. This prevents the moving part 3 from rotating around the axis of the main body 2 under the action of the rotating element, thereby preventing the reverse action on the power element, thereby causing the axial position of the moving part 3 on the main body 2 to change. This embodiment is more practical.

[0092] like Figure 4 and Figure 6 As shown, the auxiliary component 31 is annular, and the auxiliary component 31 is connected to the main body 2 via a spline.

[0093] In fact, according to actual conditions, it is also possible to choose to set the end of the main body 2 into a rectangle, open a rectangular hole on the auxiliary component 31, and cooperate with the rectangular main body 2 and the rectangular hole to complete the axial sliding installation between the auxiliary component 31 and the main body 2. This embodiment completes the axial sliding installation between the auxiliary component 31 and the main body 2 through a spline connection, which has a simple structure, is easy to install, and is highly practical.

[0094] like Figure 6 As shown, the power element includes a return spring 34, a steel wire rope 32, a sleeve 33 and a winding mechanism rotatably mounted on an external support frame;

[0095] One end of the steel wire rope 32 is connected to the auxiliary component 31, and the other end is wound on the winding mechanism;

[0096] The sleeve 33 is sleeved on the steel wire rope 32, one end of the sleeve 33 is fixedly mounted on the bracket 1, and the other end is fixedly mounted on the external support frame;

[0097] The winding mechanism is used for winding the steel wire rope 32;

[0098] A locking mechanism for fixing the winding mechanism is installed on the external support frame;

[0099] The return spring 34 is located between the retaining frame 4 and the moving member 3 and is used to drive the retaining frame 4 to move relative to the main body 2 in a direction away from the bracket 1 .

[0100] In fact, according to actual conditions, a motor can be installed on the bracket 1, and a screw can be installed on the output shaft of the motor, and then the screw can be screwed on the auxiliary component 31. The rotation of the output shaft of the motor drives the auxiliary component 31 to move back and forth, thereby realizing the back and forth movement of the moving part 3. In this embodiment, a mechanism similar to a bicycle brake line is formed through the mutual cooperation of a wire rope 32, a sleeve 33 and a winding mechanism rotatably installed on an external support frame, and the moving part 3 is moved back and forth by cooperating with a reset spring 34. The structure is simple and easy to use. At the same time, when in use, it is only necessary to fix the two ends of the sleeve 33 respectively, and the brake line can be used normally. It does not cause interference to the movement of the spraying mechanism relative to the external support frame, and is highly practical.

[0101] like Figure 6-Figure 8 As shown, the return spring 34 is a tension spring;

[0102] The moving part 3 includes a sub-frame 35, which is located at one end of the moving part 3 close to the sub-frame 31 and is sleeved on the main body 2;

[0103] One end of the tension spring is connected to the sub-frame 35, and the other end is connected to the retaining frame 4;

[0104] The moving part 3 is rotationally connected to the auxiliary part 31 via the auxiliary frame 35.

[0105] In fact, according to actual conditions, a return spring 34 composed of a compression spring can be installed at the front end of the spraying mechanism, between the retaining frame 4 and the moving part 3, so as to achieve the purpose of driving the retaining frame 4 to move away from the bracket 1 relative to the main body 2. In this embodiment, a tension spring is used as the return spring 34, which cooperates with the sub-frame 35 installed near one end of the sub-part 31. On the basis of achieving the purpose of driving the retaining frame 4 to move away from the bracket 1 relative to the main body 2, the obstruction to the front end of the spraying mechanism can be reduced, and the cleaning range of the cleaning mechanism can be increased, thereby having strong practicality.

[0106] like Figure 6-Figure 8 As shown, a second bearing 350 is installed between the sub-frame 35 and the sub-component 31 .

[0107] In fact, according to actual conditions, a shaft sleeve can be set between the sub-frame 35 and the sub-component 31, or the sub-frame 35 and the sub-component 31 can be directly sleeved with each other to achieve the rotational installation between the sub-frame 35 and the sub-component 31. In this embodiment, the rotational connection between the sub-frame 35 and the sub-component 31 is achieved through the second bearing 350, and the sliding friction between the sub-frame 35 and the sub-component 31 is converted into rolling friction, which can effectively reduce the friction force and has strong practicality.

[0108] like Figure 4 and Figure 6-Figure 8 As shown, a connecting frame 11 is fixedly installed between the bracket 1 and the main body 2, and the connecting frame 11 is in a hollow Z-shape;

[0109] One end of the connecting frame 11 is connected to the main body 2, and the other end is connected to the pipeline 10;

[0110] A plurality of auxiliary ropes 36 are evenly arranged on one end of the auxiliary component 31 away from the retaining frame 4 with the central axis of the main body 2 as the center;

[0111] A connecting ring 360 is fixedly installed at one end of the steel wire rope 32 close to the auxiliary component 31 . The connecting ring 360 is located above the connecting frame 11 and is fixedly connected to the free end of the auxiliary rope 36 .

[0112] In fact, according to actual conditions, the steel wire rope 32 can be directly fixed on the connecting frame 11, and the moving part 3 can be pulled by the steel wire rope 32 on one side of the auxiliary part 31. In this embodiment, the steel wire rope 32 is avoided through the Z-shaped connecting frame 11, the auxiliary rope 36 and the connecting ring 360, so as to avoid the problem that the pulling direction of the steel wire rope 32 cannot coincide with the central axis of the main body 2 due to the bracket 1 being directly fixed on the main body 2, and the moving part 3 is not pulled smoothly. The practicability is strong.

[0113] like Figure 5 As shown, there are multiple nozzles 6, which are evenly arranged along the circumference of the axis of the main body 2, preferably four.

[0114] In fact, according to actual conditions, only one nozzle 6 may be provided. In this embodiment, multiple nozzles 6 are evenly arranged circumferentially, so that when the retaining frame 4, the rotating element, the limiting frame 5 and the nozzle 6 rotate, their centers of gravity remain coincident with the axis of the main body 2, the rotation is more stable, and the practicality is stronger.

[0115] like Figure 5 As shown, the rotating element is composed of a nozzle 6 arranged obliquely relative to the horizontal plane;

[0116] There is a certain angle between the nozzle 6 and the vertical plane where the central axis of the main body 2 is located.

[0117] In fact, according to actual conditions, a motor can be installed on the bracket 1 to drive the retaining frame 4 to rotate. In this embodiment, an inclined nozzle 6 is used as a power source. When the nozzle 6 sprays cleaning water / high-pressure steam, the reaction force of the cleaning water / high-pressure steam is used to drive the retaining frame 4 to rotate via the limit frame 5. There is no need to install an additional power source, which is more convenient to use.

[0118] like Figure 6 As shown, the transmission element includes a gear 61 and a rack 62 that mesh with each other;

[0119] The limiting frame 5 is provided with an annular groove, the gear 61 is rotatably mounted in the annular groove, and the nozzle 6 is fixedly connected to the gear 61;

[0120] The rack 62 is fixedly mounted on the moving part 3 .

[0121] In fact, according to actual conditions, a connecting rod structure can be selected as a transmission element to realize power transmission between the nozzle 6 and the moving part 3. In this embodiment, the transmission element is formed by the gear 61 and the rack 62, so that when the power element drives the moving part 3 to move relative to the main body 2, the nozzle 6 is driven to deflect, thereby changing the angle between the nozzle 6 and the central axis of the main body 2. The structure is simple, the installation is convenient, and the practicability is strong.

[0122] like Figure 1-Figure 3 As shown, the present invention also discloses a cleaning device, including an insertion mechanism and the above-mentioned spray cleaning mechanism for cleaning a hazardous chemical tanker; the insertion mechanism includes a mounting arm 13, a bracket 1 and an external support frame;

[0123] The bracket 1 is fixedly mounted on the end of the mounting arm 13 , and the mounting arm 13 is used to drive the spray cleaning mechanism to extend into the tank body 12 .

[0124] The mounting arm 13 in the present application may be a transmission telescopic system in the Chinese invention patent (publication number: CN117463728A), which is composed of a third connecting member, a connecting rod, a second connecting member, a support rod, a pull rod, a telescopic arm and a first connecting member. This is prior art, so this application will not repeat it.

[0125] In this embodiment, when in use, the spray cleaning mechanism is extended into the interior of the tank body 12 by the mounting arm 13;

[0126] During the cleaning process, the cleaning water / high-pressure steam is supplied to the spray cleaning mechanism through the pipeline 10, and the inclined nozzle 6 is used as a power source. When the nozzle 6 sprays the cleaning water / high-pressure steam, the reaction force of the cleaning water / high-pressure steam is used to drive the retaining frame 4 to rotate through the limiting frame 5, thereby forming an annular cleaning surface;

[0127] When it is necessary to clean the front end surface of the tank body 12 (the left side of the tank body 12 in the figure), open the locking mechanism that fixes the winding mechanism, rotate the winding mechanism, and pull the retaining frame 4 to the right through the wire rope 32 to overcome the prestress of the reset spring 34, so that the retaining frame 4 moves to the left relative to the main body 2. In this process, the retaining frame 4 moves to the right relative to the limiting frame 5, and the mutual engagement of the gear 61 and the rack 62 drives the nozzle 6 on the limiting frame 5 to rotate counterclockwise until the water spraying / jet jet direction of the nozzle 6 is toward the front end, and then the pipeline 10 supplies cleaning water / high-pressure steam to the spraying mechanism, so that the front end surface of the tank body 12 (the left side of the tank body 12 in the figure) can be cleaned. Figure 8 As shown;

[0128] Similarly, by rotating the winding mechanism in the opposite direction and gradually relaxing the pull on the retaining frame 4, the retaining frame 4 can gradually move to the left under the action of the reset spring 34, and cooperate with the rotation of the retaining frame 4 around the main body 2 to form a spherical cleaning surface to complete the cleaning of the inside of the tank body 12.

[0129] The above is a detailed introduction to a spray washing mechanism and a washing device for washing hazardous chemical tank trucks provided by the present invention. The description of the specific embodiment is only used to help understand the method of the present invention and its core idea. It should be pointed out that for ordinary technicians in this technical field, without departing from the principle of the present invention, several improvements and modifications can be made to the present invention, and these improvements and modifications also fall within the scope of protection of the claims of the present invention.
