Description

Technical Field

[0001] This invention belongs to the field of mechanical technology, specifically a device for processing large workpieces. Background Technology

[0002] Cleaning large workpieces is particularly challenging. Due to their size, track-mounted suspension mechanisms cannot be used for cleaning. If a horizontally arranged cleaning method is adopted, it not only requires a large cleaning unit but also consumes a significant amount of water during the cleaning process, and the handling of the workpieces is extremely inconvenient. Summary of the Invention

[0003] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a large workpiece processing device that features convenient cleaning.

[0004] The objective of this invention can be achieved through the following technical solutions:

[0005] A large workpiece processing device, comprising:

[0006] A mounting bracket for connecting to the ground, the mounting bracket comprising a base frame and a top frame;

[0007] Several telescopic rods capable of extending and retracting along the height direction are provided. The lower ends of the telescopic rods are fixedly connected to the base frame. The telescopic rods are distributed in a circumferential array on the base frame. The telescopic rods have internal flow channels and several nozzles are opened on their surfaces. The telescopic rods include multiple slidably connected nozzles. The nozzles are set on the nozzles. The tops of multiple nozzles at the same height are fixedly connected by a fixing ring.

[0008] A shielding film, the upper end of which is fixedly connected to the uppermost end of the telescopic rod, and the lower end of which is fixedly connected to the base frame;

[0009] A suspension frame, fixed to the top frame, is equipped with a lifting device for lifting the workpiece to be cleaned;

[0010] A lifting device is used to connect to a fixed ring at its highest position, and is used to drive the telescopic rod to move up, down, and extend.

[0011] In the aforementioned large workpiece processing device, each nozzle is provided with two opposing first guide grooves, a second guide groove, a first slider located at the top of the nozzle, and a second slider located at the bottom of the nozzle. The first slider is disposed within the first guide groove, and the second slider is disposed within the second guide groove. When two adjacent nozzles slide in contact, the first slider and the first guide groove on one nozzle slide in contact with the second guide groove and the second slider on the other nozzle, respectively. The first slider can abut against the second slider vertically. The first slider is provided with a first channel, and the second slider is provided with a second channel. The first channel and the second channel respectively have a first passage and a second passage parallel to the flow channel inside the nozzle. The first passage and the second passage are arranged along the direction of gravity. When the first slider and the second slider abut against each other vertically, the first passage and the second passage can communicate with each other.

[0012] In the aforementioned large workpiece processing device, the nozzle is equipped with a self-locking mechanism. The self-locking mechanism includes two self-locking components symmetrically arranged on the first slider. Each self-locking component includes a swing rod and a support portion. The support portion is fixed to the first slider, and the middle part of the swing rod is hinged to the support portion. One end of the swing rod is connected to a spring piece, and a sliding column is fixed on the spring piece. The other end of the swing rod is equipped with a latch. The first slider has a side hole communicating with the first through portion. The side hole is perpendicular to the first through portion, and the sliding column is slidably disposed in the side hole. The second slider has a limit groove. After the first slider and the second slider can abut against each other vertically and water is introduced, the sliding column is subjected to water pressure and moves outward, driving the swing rod to swing, so that the latch on the swing rod is locked onto the limit groove to prevent the first slider and the second slider from separating.

[0013] In the above-mentioned large workpiece processing device, a compression spring is fixed on the first slider, and the compression spring can abut against the swing rod so that the pawl on the swing rod disengages from the limiting groove.

[0014] In the above-mentioned large workpiece processing device, an annular groove is provided around the first through portion on the lower surface of the first slider, and a sealing ring is installed in the annular groove. When the first slider and the second slider abut against each other, the sealing ring abuts against the second slider.

[0015] In the above-mentioned large workpiece processing device, the lifting device includes two winches and two guide wheels. The two guide wheels are rotatably mounted on the top frame of the fixed frame. The two winches are fixed on both sides of the fixed frame respectively. The ropes of the two winches are wound around the two guide wheels respectively, and the ends of the ropes are fixedly connected to the fixed rings.

[0016] In the above-mentioned large workpiece processing device, the nozzle is located at the bottom of the first guide groove, and a nozzle head is installed inside the nozzle.

[0017] In the aforementioned large workpiece processing device, several nozzles at the same height have fixing rings at their lower ends.

[0018] Compared with the prior art, this application has the following advantages:

[0019] In this application, firstly, the fixed frame is stably connected to the ground via the base frame, while the top frame provides a support structure for the suspension frame. When large workpieces need to be processed, the lifting device on the suspension frame is used to lift the workpiece to be cleaned and suspend it in a suitable position. Then, the lifting device drives the fixed ring at the highest position to move. Since the tops of multiple nozzles at the same height are fixedly connected by the fixed ring, the lifting of the fixed ring will cause the telescopic rod to extend and retract. Cleaning fluid or water and other cleaning media are transported through the flow channel inside the telescopic rod and then sprayed out from the nozzle on the nozzle to clean the suspended large workpiece from multiple directions. The shielding film plays a role in the whole process, preventing the cleaning fluid from splashing everywhere, making the cleaning process relatively closed and concentrated.

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0034] like Figures 1 to 4 As shown, a large workpiece processing device includes: a fixed frame 2 for connection to the ground, several telescopic rods 3 capable of extending and retracting along the height direction, a shielding membrane 4, a suspension frame 5, and a lifting device 6. The fixed frame 2 includes a base frame 21 and a top frame 22. The lower ends of the telescopic rods 3 are fixedly connected to the base frame 21, and the telescopic rods 3 are distributed in a circumferential array on the base frame 21. The telescopic rods 3 have a flow channel 31 inside and several nozzles 32 are opened on the surface of the telescopic rods 3. The telescopic rods 3 include multiple slidably connected nozzles 33, and the nozzles 32 are set on the nozzles 33. The top ends of the multiple nozzles 33 at the same height are fixedly connected by a fixing ring 34. The upper end of the shielding membrane 4 is fixedly connected to the uppermost end of the telescopic rod 3, and the lower end of the shielding membrane 4 is fixedly connected to the base frame 21. The suspension frame 5 is fixed to the top frame 22, and the suspension frame 5 is provided with a lifting device 7 for lifting the workpiece to be cleaned. The lifting device 6 is used to connect to the fixing ring 34 at the highest position and is used to drive the telescopic rods 3 to extend and retract.

[0035] In this application, firstly, the fixed frame 2 is stably connected to the ground via the base frame 21, and the top frame 22 provides a support structure for the suspension frame 5. When large workpieces need to be processed, the lifting device 7 on the suspension frame 5 is used to lift the workpiece to be cleaned and suspend it in a suitable position. Then, the lifting device 6 drives the fixed ring 34 at the highest position to move. Since the tops of multiple nozzles 33 at the same height are fixedly connected via the fixed ring 34, the lifting of the fixed ring 34 will cause the telescopic rod 3 to extend and retract. The cleaning medium, such as cleaning fluid or water, is transported through the flow channel 31 inside the telescopic rod 3 and then sprayed out from the nozzle 32 on the nozzle 33 to clean the suspended large workpiece from multiple directions. The shielding membrane 4 plays a role in the whole process, preventing the cleaning fluid from splashing everywhere, making the cleaning process relatively closed and concentrated.

[0036] In practical applications, a trench can be dug in the ground, and the large workpiece handling device can be installed in it. The trench depth is set to the height of one nozzle 33. In this way, the device is basically flush with the ground when not in use, which is extremely convenient for hoisting large workpieces. In addition, the workpiece can be set vertically, and no excessive handling space needs to be reserved during transportation. The large workpiece handling device focuses on the height issue, which greatly reduces its footprint.

[0037] Specifically, each nozzle 33 is provided with two opposing first guide grooves 331, second guide grooves 332, a first slider 333 located at the top of the nozzle 33, and a second slider 334 located at the bottom of the nozzle 33. The first slider 333 is disposed in the first guide groove 331, and the second slider 334 is disposed in the second guide groove 332. When two adjacent nozzles 33 are in sliding engagement, the first slider 333 and the first guide groove 331 on one nozzle 33 are respectively in sliding engagement with the second guide groove 332 and the second slider 334 on the other nozzle 33. 33 can abut against the second slider 334 vertically; the first slider 333 is provided with a first channel 3331, and the second slider 334 is provided with a second channel 3341. The first channel 3331 and the second channel 3341 respectively have a first passage 33311 and a second passage 33411 parallel to the flow channel 31 inside the nozzle 33. The first passage 33311 and the second passage 33411 are arranged along the direction of gravity. When the first slider 333 and the second slider 334 abut against each other vertically, the first passage 33311 and the second passage 33411 can communicate.

[0038] When the device is running, when the length of the telescopic rod 3 needs to be adjusted, relative sliding will occur between adjacent nozzles 33. The first slider 333 at the top of one nozzle 33 slides in the first guide groove 331 of its own nozzle 33, and at the same time cooperates with the second slider 334 and the second guide groove 332 at the bottom of the other nozzle 33 to achieve a stable sliding connection structure. During this process, as the nozzles 33 extend and retract, when the first slider 333 and the second slider 334 abut against each other, the first passage 33311 of the first channel 3331 on the first slider 333 and the second passage 33411 of the second channel 3341 on the second slider 334 are connected along the direction of gravity. This ensures that the cleaning medium can be smoothly transmitted between the flow channels 31 in each nozzle 33 under the maximum stroke state. Starting from the bottom nozzle 33, the cleaning medium enters each nozzle 33 in sequence through the connected passages and is finally sprayed out from the nozzle 32 to clean the large workpiece.

[0039] Through the cooperative design of the first guide groove 331, the second guide groove 332, the first slider 333, and the second slider 334, the adjacent nozzles 33 are tightly connected and slide smoothly during the extension and retraction process, thereby ensuring the stability and reliability of the entire telescopic rod 3 structure under different working conditions.

[0040] Specifically, the nozzle 33 is provided with a self-locking mechanism 8, which includes two self-locking components symmetrically arranged on the first slider 333. Each self-locking component includes a swing rod 81 and a support part 82. The support part 82 is fixed to the first slider 333, and the middle part of the swing rod 81 is hinged to the support part 82. One end of the swing rod 81 is connected to a spring piece 83, and a sliding post 84 is fixed on the spring piece 83. The other end of the swing rod 81 is provided with a latch 85. The first slider 333 has a first communication part 33311. A side hole 3332 is connected and perpendicular to the first through part 33311. A sliding post 84 is slidably disposed in the side hole 3332. A limiting groove 3342 is provided on the second slider 334. After the first slider 333 can abut against the second slider 334 and water is introduced, the sliding post 84 is moved outward by water pressure and drives the swing rod 81 to swing, so that the pawl 85 on the swing rod 81 is fastened to the limiting groove 3342 to prevent the first slider 333 and the second slider 334 from separating.

[0041] When the large workpiece processing device starts working, and the cleaning medium such as cleaning water is introduced into the flow channel 31 in the nozzle 33, the water flow will enter the second passage 33411 on the second slider 334. Since the first slider 333 has a side hole 3332 that is perpendicular to and connected to the first passage 33311, after the water flows into the first passage 33311, the sliding column 84 that is slidably arranged in the side hole 3332 will be subjected to water pressure.

[0042] As water pressure is applied, the sliding column 84 moves outward along the side hole 3332. The sliding column 84 is fixed on the spring piece 83, which is connected to the swing rod 81. The outward movement of the sliding column 84 will cause the swing rod 81 to swing around the hinge point between it and the support part 82. One end of the swing rod 81 is provided with a pawl 85. During the swinging process, when the first slider 333 and the second slider 334 abut against each other, the pawl 85 on the swing rod 81 will gradually approach the limiting groove 3342 opened on the first slider 333 and finally lock onto the limiting groove 3342.

[0043] By engaging the latch 85 with the limiting groove 3342, the first slider 333 and the second slider 334 are restricted in the vertical direction, effectively preventing them from separating due to external forces or other factors. This ensures that the adjacent nozzles 33 maintain a stable connection during the extension and water cleaning process, ensuring the stability and reliability of the entire telescopic rod 3 structure, allowing the cleaning work to proceed smoothly, and enabling the cleaning medium to be continuously sprayed from the nozzle 32 through each nozzle 33 to clean the large workpiece.

[0044] The self-locking mechanism 8 ensures that the first slider 333 and the second slider 334 can be firmly connected during operation, especially under complex conditions such as the introduction of cleaning medium, water pressure, and possible external interference. This greatly enhances the stability of the connection between the nozzles 33 and avoids problems such as damage to the telescopic rod 3 structure or interruption of cleaning due to accidental loosening or separation. It ensures the continuity of cleaning operations and the reliable operation of the device. The entire self-locking mechanism 8 is mainly composed of relatively simple components such as the swing rod 81, the support part 82, the spring piece 83, and the sliding column 84. Through clever hinges and cooperation with each component, the self-locking function is achieved by using the pressure of the water flow itself as the triggering power, without the need for additional complex drive devices or control systems.

[0045] Specifically, a compression spring 86 is fixed on the first slider 333. The compression spring 86 can abut against the swing rod 81 so that the pawl 85 on the swing rod 81 disengages from the limiting groove 3342.

[0046] When it is necessary to release the locked state of the first slider 333 and the second slider 334, it can be achieved, for example, by acting on the compression spring 86. The compression spring 86 is fixed on the first slider 333. In its initial state, it applies a certain force to the swing rod 81. When it is necessary to unlock, the internal water pressure disappears, and then under the action of the compression spring 86, the latch 85 can disengage from the limiting groove 3342.

[0047] Specifically, an annular groove is provided on the lower surface of the first slider 333 around the first through portion 33311, and a sealing ring 9 is installed in the annular groove. When the first slider 333 and the second slider 334 abut against each other, the sealing ring 9 abuts against the second slider 334.

[0048] The sealing ring 9 is installed in the annular groove surrounding the first through portion 33311 on the lower surface of the first slider 333. When the first slider 333 and the second slider 334 abut against each other vertically, the sealing ring 9 abuts tightly against the second slider 334. This design effectively prevents the cleaning medium from leaking at the connection between the first slider 333 and the second slider 334.

[0049] Specifically, the lifting device 6 includes two winches 61 and two guide wheels 62. The two guide wheels 62 are rotatably mounted on the top frame 22 of the fixed frame 2. The two winches 61 are fixed on both sides of the fixed frame 2 respectively. The ropes of the two winches 61 are wound around the two guide wheels 62 respectively, and the ends of the ropes are fixedly connected to the fixed ring 34.

[0050] When the height of the telescopic boom 3 needs to be adjusted, the winches 61 on both sides are started. The winches 61 rotate to wind up and down the rope. The rope first changes direction by passing around the guide wheel 62 set on the top frame 22, and then connects to the fixed ring 34. When the winch 61 winds up the rope, the rope generates an upward pulling force on the fixed ring 34. Since the fixed ring 34 connects the top of the nozzle 33 at the same height, this pulling force will drive the entire telescopic boom 3 to rise, realizing the ascending action. When the winch 61 releases the rope, under the action of the telescopic boom 3's own weight, the telescopic boom 3 will move downward along the rope, thus completing the descending action.

[0051] Specifically, the nozzle 32 is located at the bottom of the first guide groove 331, and the nozzle 321 is installed inside the nozzle 32.

[0052] Specifically, a retaining ring 35 is fixed to the lower end of several nozzles 33 at the same height.

[0053] The lower ends of the nozzles 33 at the same height are fixed with retaining rings 35, so that these nozzles 33 form a relatively stable overall structure in the horizontal direction.
