Rust removal machine with lifting and lowering part

Abstract

The rust removal machine with a liftable rust removal part provided by the present invention comprises a rust removal part for removing rust from a surface to be rusted, and also comprises a lifting part sleeved on the rust removal part and a driving device for driving the lifting part to rotate. One of the lifting part and the side wall of the rust removal part is provided with a threaded track, and the other is provided with a spiral rigid part. The spiral rigid part is rotatably mounted on the threaded track, and the lifting part is driven to rotate relative to the rust removal part to control the lifting of the rust removal part. Under the premise of ensuring its lifting function, it no longer relies on friction to prevent the gravity of the rust removal part from doing work. It only needs to ensure that the spiral rigid part can be placed on the threaded track so that the rust removal part will not fall off. Therefore, the length of the connection section between the two for connecting each other can be reduced, thereby saving the height space of the rust removal machine and making the structure of the rust removal machine more compact.

Description

Technical Field

[0001] The invention relates to a rust remover, in particular to a rust remover with a rust removing part capable of being lifted and lowered. Background Art

[0002] In the prior art, the lifting device of the rust removal part of the rust removal machine is shown in Chinese patent CN201820025992.7. Mainly, it discloses the use of the structure of a threaded rod and a threaded sleeve to control the lifting of the rust removal part so as to adapt to the rust removal surfaces of different heights. The threaded rod and the threaded sleeve in the prior art are used as transmission parts. Generally speaking, the rust removal part is not directly installed on the threaded rod or the threaded sleeve.

[0003] However, in actual use, it is found that some surfaces to be derusted are located in corners with height restrictions, and the existing derusting machine is too high to enter the corners for derusting. The reason is that the lifting device occupies a large height space, resulting in the structure of the derusting machine not being compact enough.

[0004] In the prior art, one lifting scheme is to install the rust removal part on the threaded sleeve, and the threaded rod drives the threaded sleeve to lift and lower to control the lifting and lowering of the rust removal part, thereby saving the height space of the rust removal machine. However, it is found in actual application that if the surface to be rusted is on the ground, the threaded rod must drive the threaded sleeve to descend so that the rust removal part is close to the surface to be rusted. At this time, a problem arises: the threaded sleeve is installed on the rust removal machine only by the connection with the threaded rod, and it relies on the friction between the threaded sleeve and the threaded rod to overcome the gravity work of the threaded sleeve and the rust removal part. In other words, a threaded rod with a total length of LA, a part of which has a length of LB must be threadedly connected to the threaded sleeve to provide a sufficiently large friction force, otherwise the threaded sleeve and the rust removal part will fall off the threaded rod due to the work done by their gravity. Although the height space of the rust remover needs to be saved, the distance LA-LB cannot be reduced indefinitely because the lifting distance of the rust removal part must be guaranteed. Therefore, when LA-LB is a fixed value, the inventor thought of reducing LB to reduce the total length LA of the threaded rod, thereby saving the height space of the rust remover and making the rust remover more compact in height space. Summary of the invention

[0005] In order to overcome the deficiencies of the prior art, the present invention aims to provide a rust remover with a liftable rust removal portion, which is used to shorten the length LB connecting the threaded rod and the threaded sleeve, thereby saving the height space of the rust remover and making the structure more compact.

[0006] A rust removal machine with a liftable rust removal part comprises a rust removal part for removing rust from a surface to be rusted, a lifting part sleeved on the rust removal part and a driving device capable of driving the lifting part to rotate, one of the lifting part and the outer wall of the rust removal part is provided with a threaded track, and the other is provided with a spiral rigid part, the spiral rigid part is rotatably mounted on the threaded track, and the driving device drives the lifting part to rotate relative to the rust removal part to lift and lower the rust removal part.

[0007] Furthermore, a threaded track is arranged on the side wall of the rust removal part, and an annular baffle is arranged on the circumference of the lower part of the rust removal part for preventing the spiral rigid part from escaping from the threaded track, and the annular baffle is fixed to the rust removal part through a connecting transverse plate.

[0008] Furthermore, it also includes a base fixed below the rust removal part, a stopper is provided at the bottom of the rust removal part, and a stopper is provided on the base to abut against the stopper to prevent the rust removal part from rotating.

[0009] Furthermore, the stop portion is an open groove, the stop piece is a convex block extending downward, and the convex block is embedded in the open groove.

[0010] Furthermore, a horizontal transmission gear is fixedly provided above the lifting part, and the driving device includes an output end arranged on one side of the transmission gear, and the output end is meshed with the transmission gear.

[0011] Furthermore, the threaded track is a threaded groove, and the spiral rigid member can be embedded in the threaded track so as to rotate relative to the threaded track.

[0012] Furthermore, the cross section of the channel is rectangular, and the shape and size of the spiral rigid member match the channel.

[0013] Furthermore, a horizontal transmission gear is fixedly provided above the lifting part, and the driving device includes an output end arranged on one side of the transmission gear, and the output end is meshed with the transmission gear.

[0014] Furthermore, the rust remover includes a distance sensor for measuring the height difference between the front and rear surfaces to be rusted in the direction of travel of the rust remover. After the distance sensor transmits a signal to a driving device, the driving device drives the rust removal part to rise and fall accordingly according to the signal so that the rust removal part can remove rust from the surface to be rusted.

[0015] Furthermore, the end of the rust removal part is a cutter head for rust removal.

[0016] Furthermore, it also includes a negative pressure generating device and a rust block recovery chamber arranged on one side of the rust removal part, and the negative pressure generating device is connected to the rust block recovery chamber.

[0017] The rust removal part is installed on the threaded track through a spiral rigid part, that is, the threaded track supports the spiral rigid part, so that the rust removal part and the lifting part will not separate from each other due to their own weight. Under the premise of ensuring its lifting function, it is no longer necessary to rely on friction to prevent the gravity of the rust removal part from doing work. It only needs to ensure that the spiral rigid part can be rotatably connected to the threaded track, and the rust removal part and the lifting part will not separate from each other. Therefore, the length of the LB described in the background technology can be greatly reduced, thereby saving the height space of the rust removal machine and making the structure of the rust removal machine more compact.

[0023] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0024] like Figure 1-4As shown, the rust removal machine with a rust removal part 1 that can be lifted and lowered comprises the rust removal part 1 for removing rust from the surface to be rusted, and also comprises a lifting part sleeved on the rust removal part 1 and a driving device 7 capable of driving the lifting part to rotate, one of the lifting part and the outer wall of the rust removal part 1 is provided with a threaded track 3, and the other is provided with a spiral rigid member 5, the spiral rigid member 5 is rotatably mounted on the threaded track 3, and the driving device 7 drives the lifting part to rotate relative to the rust removal part 1 to lift and lower the rust removal part 1. The working principle is as follows: the rust removal part 1 is placed on the threaded track 3 through the spiral rigid member 5, that is, the threaded track 3 lifts the spiral rigid member 5, so that the rust removal part 1 will not fall off the threaded track 3 due to its own gravity. When the rust removal part 1 is driven to rise and fall, the driving device 7 drives the lifting part to drive the spiral rigid part 5 to rotate. When the spiral rigid part 5 rotates, the position of the spiral track 3 changes. In practice, the spiral track 3 and the spiral track 3 are deliberately made as smooth as possible, so that the friction force is insufficient. In order to maintain the original relative position with the spiral rigid part 5, the spiral track 3 makes the rust removal part 1 rise or fall. The beneficial effect is that, under the premise of ensuring its lifting function, the friction force is no longer relied on to prevent the gravity of the rust removal part 1 from doing work. It is only necessary to ensure that the spiral rigid part 5 can be placed on the threaded track 3 so that the rust removal part 1 will not fall off, so the length of the LB described in the background technology can be greatly reduced, thereby saving the height space of the rust removal machine and making the structure of the rust removal machine more compact. It should be noted that the spiral rigid part 5 does not produce deformation in the present technical solution, which is different from the spring in the prior art.

[0025] Furthermore, in order to prevent the spiral rigid member 5 from accidentally detaching from the lower part of the rust removal portion 1, a threaded track 3 is provided on the side wall of the rust removal portion 1, and an annular baffle 4 is provided on the peripheral side of the lower part of the rust removal portion 1 to prevent the spiral rigid member 5 from escaping from the threaded track 3, and the annular baffle 4 is fixed to the rust removal portion 1 by connecting the cross plate.

[0026] Furthermore, it also includes a fixed base below the rust removal part 1, a stopper is provided at the bottom of the rust removal part 1, and a stopper is provided on the base to abut against the stopper to prevent the rust removal part 1 from rotating. Furthermore, the stopper is an open groove 8, and the stopper is a convex block extending downward, and the convex block is embedded in the open groove 8. In order to prevent the friction between the spiral rigid part 5 and the threaded track 3 from affecting the start of the rust removal part 1 when it is lifted or lowered, an open groove 8 and a stopper that are mutually embedded when they are in contact are provided to prevent the friction between the spiral rigid part 5 and the threaded track 3 from being too large, thereby preventing the rust removal part 1 from rotating when the lifting part rotates, causing the rust removal part 1 to be unable to be lifted or lowered.

[0027] Furthermore, the threaded track 3 is a threaded groove, and the spiral rigid member 5 can be embedded in the threaded track 3 so as to rotate relative to the threaded track 3. The advantage of such a configuration is that the threaded track 3 supports the spiral rigid member 5, and the supporting force provided is much greater than the solution in the prior art that provides the supporting force by friction, so the required LB can be greatly shortened, thereby significantly saving height space and making the rust remover structure more compact.

[0028] Furthermore, the threaded track 3 is a threaded groove, and the spiral rigid member 5 can be embedded in the threaded track 3 so as to rotate relative to the threaded track 3. The significance of the spiral rigid member 5 being embedded in the threaded groove is that the threaded track 3 provides a larger support surface, thereby increasing the contact area with the spiral rigid member 5 and providing a greater support force.

[0029] Furthermore, the cross section of the channel is rectangular, and the shape and size of the spiral rigid member 5 match the channel.

[0030] Furthermore, a horizontal transmission gear 6 is fixedly disposed above the lifting part, and the driving device 7 includes an output end disposed on one side of the transmission gear 6, and the output end is meshed with the transmission gear 6. The driving device 7 is a prior art, and can be a motor or a stepping motor.

[0031] Furthermore, the rust remover includes a distance sensor 12 and a processor for measuring the height difference of the front and rear surfaces to be rusted in the direction of travel of the rust remover. After the distance sensor 12 transmits a signal to the processor, the processor controls the driving device 7 according to the signal to drive the rust removal part 1 to rise and fall accordingly so that the rust removal part 1 can remove rust from the surface to be rusted. When the two distance sensors 12 arranged one before and one after the rust remover encounter an inclined surface to be rusted, they transmit signal data to the processor to calculate the difference in distance from the front and rear of the rust remover to the surface to be rusted, thereby calculating the height to which the rust removal part 1 should rise and fall, so that the rust removal part 1 can reach the surface to be rusted for rust removal.

[0032] Furthermore, the end of the rust removal part 1 is a cutter head for rust removal.

[0033] Furthermore, it also includes a negative pressure generating device and a rust block recovery chamber arranged on one side of the rust removal part 1, and the negative pressure generating device is connected to the rust block recovery chamber.

[0034] The above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
