[0047] Example 1

[0048] Reference Figure 1 and Figure 2 , which is the first embodiment of the present invention, provides a rust removal device for steel structure buildings, comprising the following parts:

[0049] The moving part 1 has a structure that ensures that the moving part 1 can move along the length of the steel beam.

[0050] The first grinding part 2 and the second grinding part 3 are both arranged on the moving part 1 and are used to grind the bottom and the side of the steel beam respectively, so as to complete the rust removal work. The number of the second grinding parts 3 is at least two, so as to act on both sides of the steel beam respectively, and the second grinding parts 3 can move relative to the moving part 1;

[0051] The energy supply part is relatively independent from the moving part 1. The first grinding part 2, the second grinding part 3 and the moving part 1 are all powered by the energy supply part to move. The second grinding part 3 is also powered by the energy supply part to move on the moving part 1.

[0052] The present invention is normally Figure 1 , Figure 2 In the state shown, the two second moving parts 1 are separated, which can facilitate the moving part 1 to be taken and placed from the steel beam. Fig.10 and Fig.11By setting the moving part 1 on the steel beam, the first grinding part 2 contacts the bottom of the steel beam, and the energy supply part provides power to move the two second grinding parts 3 on the moving part 1 to a state of being close to each other, so as to form contact with both sides of the steel beam respectively, thereby achieving rust removal on the surface of the steel beam;

[0053] In the above process, the energy supply unit is operated by a person standing on the ground, thereby controlling the movement of the moving unit 1 on the steel beam, the work of the first grinding unit 2 and the second grinding unit 3. After the rust removal work is completed, the two second grinding units 3 are controlled to move on the moving unit 1 to Figure 1 The state shown in the figure can be removed from the steel beam. During the whole process, the present invention can automatically remove rust from multiple surfaces of the steel beam and move on the steel beam at the same time, thereby ensuring the efficiency of rust removal. At the same time, compared with the purely manual rust removal method in the prior art, the rust removal process of the present invention is safer.

[0054] The above is a basic description of the present invention. The specific structure of the present invention will be further described below in conjunction with more drawings. Specifically:

[0055] Reference Figure 1-3 The movable part 1 comprises a base 101 and a contact wheel 102 rotatably arranged on the base 101, the contact wheel 102 is used to contact the steel beam, the number of the contact wheels 102 is multiple, and 4 are arranged in the figure, which is used as a reference. The setting position of the contact wheel 102 on the base 101 is configured to be adjustable. When multiple contact wheels 102 are put together, they can be matched and clamped on the steel beam to realize the setting of the movable part 1 on the steel beam. On the contrary, when a sufficient distance is maintained between the multiple contact wheels 102, the clamping relationship can be released, so that it is convenient to remove the movable part 1 from the steel beam. At least two of the contact wheels 102 are provided with power-assisting elements that can be rotated by airflow. As for the function of the energy supply part, it is used to provide high-pressure airflow. The energy supply part can adopt elements such as air pumps, and is connected to the power-assisting element through a longer connecting pipe. When the energy supply part is operated to provide airflow to the power-assisting element, the rotation of the contact wheel 102 can be realized to realize the movement of the movable part 1 on the steel beam;

[0056] Further, regarding the adjustment method of the contact wheel 102, such as Figure 6 As shown, the sliders 12 corresponding in number to the contact wheels 102 can be slidably arranged on the base 101, and the contact wheels 102 are rotatably arranged on the sliders 12. The base 101 is also rotatably arranged with threaded rods 13, which are threadedly matched with the sliders 12, so that the rotation process of the threaded rods 13 can be adjusted to realize the movement of the sliders 12 on the base 101, that is, the position adjustment process of the contact wheels 102 on the base 101 is realized, as shown in FIG. Figure 8As shown, the contact wheel 102 is composed of a shaft body 102a and a wheel body 102b. The wheel body 102b is set on the shaft body 102a by a long bolt, so that the wheel body 102b can be replaced, so that when encountering steel beams with different thicknesses, the present invention can be taken into account during the working process. The surface of the wheel body 102b is a rubber layer with textures, so as to reduce or avoid the phenomenon of slipping on the surface of the steel beam; the assisting element here can be a rotating nozzle 14, which is coaxially fixedly connected with the shaft body 102a, and one end of the rotating nozzle 14 is rotatably provided with a pipe joint 15 for connecting an external pipeline, and the pipeline for receiving the airflow from the energy supply unit is connected to the pipe joint 15 to supply air to the rotating nozzle 14;

[0057] Reference Figure 1 and Figure 2 Regarding the activity of the second polishing part 3 on the base 101, specifically, the present invention further includes a support part 4 and a push part that moves through airflow, the second polishing part 3 is arranged on the support part 4, the support part 4 is movably arranged on the base 101, and an elastic reset relationship is configured on the base 101, so that in normal state, together with the second polishing part 3, it is in a fixed position on the base 101 (i.e. Figure 1 , Figure 2 The state shown), the pushing part is arranged on the base 101, and is used to push the supporting part 4. The pushing part pushes the supporting part 4 under the action of the airflow, so that the supporting part 4 breaks free from the elastic force and moves, thereby maintaining the moving process of the second grinding part 3. When the thrust is released, it is reset to the original position under the action of the elastic force. An air path matching relationship is established between the pushing part and the assisting element. The pushing part shares the same air path with the first grinding part 2 and the second grinding part 3, thereby realizing the rust removal work by receiving the airflow from the energy supply part. The assisting element is connected with the energy supply part through another air path, and the two air paths enter into work respectively, thereby realizing the grinding and moving processes respectively.

[0058] For the structure of the driving part, such as Figure 2 and Figure 7 As shown, it includes an air cylinder 16, a piston rod 17 is arranged in the air cylinder 16, the air cylinder 16 is fixedly arranged on the base 101, and air inlet valves are arranged near the two ends of the air cylinder 16, and the air inlet valves are used to connect to the external pipeline. As shown by the arrows in the figure, the airflow from the energy supply part enters the air cylinder 16 through one of the air inlet valves, so that the internal piston rod 17 can be pushed. When the piston rod 17 moves to avoid the other air inlet valve, the airflow flows out of the air cylinder 16, and the effect of the piston rod 17 being automatically pushed out when the airflow passes through the air cylinder 16 is achieved. The end of the piston rod 17 is connected to a support plate 18, and the support plate 18 is used to contact the support part 4, so that the support part 4 can be pushed when the piston rod 17 is pushed out;

[0059] Further, see Figure 1 , Figure 2 as well as Fig.10 and Fig.11 , the first grinding part 2 and the second grinding part 3 are both working in a rotating state. Specifically, the first grinding part 2 is rotatably arranged on the base 101, and the second grinding part 3 is also rotatably arranged on the support part 4. When the support part 4 moves to a fixed point position on the base 101 (keeping the second grinding part 3 in contact with the side of the steel beam, that is, Fig.10 As shown in the figure, the first grinding part 2 and the second grinding part 3 form a transmission cooperation relationship. Therefore, when configuring the driving mode of the first grinding part 2 and the second grinding part 3, it is only necessary to configure the driving force for one of them, so that the transmission can be used to realize the synchronous operation of the first grinding part 2 and the second grinding part 3;

[0060] Specifically, for the structural configuration of the first polishing part 2 and the second polishing part 3, as shown in FIG. Figure 1-3 as well as Figure 5 As shown, the first grinding part 2 and the second grinding part 3 are both of a rotary wheel structure, and grinding elements are arranged on their circumferences. Specifically, a plurality of spring sheets 19 are arranged in an array on the circumferences of both, and sandpaper 20 is adhered to the spring sheets 19. In addition, a spring sheet 19 and sandpaper 20 are also arranged at the end of the second grinding part 3. When the first grinding part 2 rotates, the bottom of the steel beam is ground, and when the second grinding part 3 rotates, the three inner concave surfaces of the side of the steel beam are ground. The sandpaper 20 is arranged on the spring sheet 19 by adhesion to ensure that it can be replaced. At the same time, when encountering a steel beam of larger or smaller size, the size adaptation effect can be achieved by replacing sandpaper 20 of different sizes;

[0061] Further, for the transmission mode between the first grinding part 2 and the second grinding part 3, refer to Figure 3-5 The present invention also includes a transmission part 5, the support part 4 is rotatably matched with the first grinding part 2, and through the elastic reset relationship, the support is in a normal state. Figure 1In the state shown, the rotation axis of the support part 4 on the first grinding part 2 is consistent with the rotation axis of the first grinding part 2 on the base 101. Specifically, one end of the support part 4 is rotatably sleeved on the first grinding part 2, and the transmission part 5 is rotatably matched with the support part 4, and the rotation axis is consistent with the rotation axis of the first grinding part 2 on the base 101. The transmission part 5 also forms a pulley matching relationship with the second grinding part 3 (it can be a chain belt matching a gear plate, a chain belt matching a sprocket or a steel belt matching a rotating wheel), so that the second grinding part 3 and the transmission part 5 are connected. A synchronous rotation relationship is always formed, and a contact transmission is formed between the transmission part 5 and the first transmission part 5. Specifically, when the support part 4 moves to keep the transmission part 5 in contact with the first grinding part 2, a transmission relationship is formed between the transmission part 5 and the first grinding part 2. At this time, the second grinding part 3 is in full contact with the side of the steel beam at the same time. Therefore, when the support part 4 moves to keep the second grinding part 3 in full contact with the side of the steel beam, the first grinding part 2 and the second grinding part 3 form a transmission effect. When one of them is driven to rotate, grinding and rust removal can be performed;

[0062] like Fig.12 and Fig.13 As shown, here, when other steel beams are welded to the steel beam being polished, through the rotational cooperation relationship between the support part 4 and the first polishing part 2 and the elastic reset relationship thereof, when the moving part 1 passes through the place where other steel beams are welded during the movement, the support part 4 can swing down under the action of the obstruction to avoid the steel beam, so that the support part 4 and the second polishing part 3 bypass the steel beam that causes the obstruction together. After the whole passes through this section of position, the support part 4 is reset to the position under the elastic reset relationship. Figure 1 In the state shown, the structure ensures that the moving part 1 can smoothly move on the steel beam;

[0063] like Figure 3-5 As shown, one side surface of the transmission part 5 and one end surface of the first grinding part 2 are both friction surface structures. When the two are in contact, a hard connection is formed by high friction, thereby forming a transmission effect. Alternatively, in order to further increase the transmission effect or prevent relative sliding, teeth can also be constructed on the friction surface to form mutual engagement through mutual contact;

[0064] For the driving process of the first grinding part 2 or the second grinding part 3, as Figure 1 as well as Figure 3 As shown, at least one of the support parts 4 is fixedly provided with a pneumatic motor 6, and the second polishing part 3 is fixedly provided on the output end of the pneumatic motor 6. When the pneumatic motor 6 is connected to the airflow from the energy supply part to work, the first polishing part 2 and the second polishing part 3 perform polishing work;

[0065] like Fig. 9As shown, the pneumatic motor 6 is connected to the air circuit of the assisting element, so that they can jointly receive the air source from the energy supply part, and the two form a branch matching relationship. Specifically, after the airflow from the energy supply part comes out, it passes through the first solenoid valve 21. The first solenoid valve 21 is a one-inlet and two-outlet control valve, and the two outlets are kept open respectively. The two outlets are respectively connected to the first pipeline 22 and the second pipeline 23. The two pushing parts and the pneumatic motor 6 are connected in series on the first pipeline 22 in sequence, and the assisting element is arranged on the second pipeline 23. Through the control of the first solenoid valve 21, the airflow enters the first pipeline 22 or the second pipeline 23 respectively, thereby realizing the grinding process or the moving process of the moving part 1 respectively.

[0066] Furthermore, the combination structure of the rotating nozzle 14 and the contact wheel 102 can be provided in multiple numbers and divided into two groups, such as Fig.17 As shown, the rotation directions of the two groups of rotating nozzles 14 are opposite. When the rotating nozzles 14 in any group work alone, the moving part 1 is controlled to move in one direction on the steel beam. The two groups of rotating nozzles 14 respectively control the moving part to move in two directions on the steel beam. Therefore, for the structure of the second pipeline 23, the following can also be adopted: Fig.18 As shown in , specifically, two groups of rotating nozzles 14 (boosting elements) are connected in parallel to the second pipeline 23, and a second solenoid valve 27 is configured on the second pipeline 23 to respectively control the air supply process of the two groups of rotating nozzles 14, so as to respectively realize the movement process of the moving part 1 in two directions on the steel beam. The structure of the second solenoid valve 27 is consistent with that of the first solenoid valve 21, which is a one-in-two-out type; the first solenoid valve 21 and the second solenoid valve 27 can be powered by a line, which is connected to the ground through the line, and a handheld power supply device (such as a mobile power supply) is configured to facilitate the operator to operate;

[0067] like Fig.10As shown in the perspective, the rotation direction of the second grinding part 3 on one side of the steel beam in the figure is clockwise, thereby driving the first grinding part 2 to rotate clockwise as well. When the second grinding part 3 rotates at high speed, the friction between its circumferential side and the two relatively concave sides of the steel beam is in opposite directions, and the friction between the end face and the inner wall of the steel beam is circumferential. Therefore, during the high-speed rotation of the second grinding part 3, it does not form a tendency to move on the steel beam, while the first grinding part 2 only contacts with the bottom of the steel beam. During the high-speed rotation, the friction force of the circumferential position will form a tendency to move to the left side of the figure, so that it can automatically move on the steel beam during the grinding process, thereby facilitating the grinding of rust stains that are distributed over a long distance on the steel beam. During the movement of the mobile part 1 on the steel beam, when encountering a place without rust, the air flow is controlled to enter the second pipeline 23 separately to make the power-assisting element work, thereby keeping the first grinding part 2 and the second grinding part 3 stopped working, so that the mobile part 1 can only move; in addition, in order to further increase the use effect of the present invention, the mobile part 1 can also be equipped with a rust detection element, such as a grating sensor, so as to judge the presence of rust by color detection, and establish a signal linkage relationship with the first solenoid valve 21, so as to control the opening of the first pipeline 22 and the second pipeline 23 accordingly, so as to keep the present invention moving while removing rust on the steel beam, or only moving;

[0068] Reference Figure 3-5 The first grinding part 2 and the second grinding part 3 are both constructed with a connected storage chamber 7 and an air suction hole 8. The base 101 is also provided with a guide chamber 9. The first grinding part 2 is fixedly connected with an exhaust element located in the guide chamber 9. The exhaust element can be an impeller 24 or a wind wheel. The storage chamber 7 is connected with the guide chamber 9. During the rust removal and grinding process, the high-speed rotation of the first grinding part 2 drives the rotation of the exhaust element, so that an air suction effect is formed in the guide chamber 9. The rust dust ground off the steel beam is sucked into the storage chamber 7 by the air suction hole 8 and finally reaches the guide chamber 9. The guide chamber 9 is provided with a discharge port, which can be connected to a collection pipe leading to the ground, so that the dust is collected and transmitted to the ground. This structure can effectively reduce the falling of dust, thereby reducing the pollution caused during the rust removal process.

[0069] like Fig.10 As shown in the perspective, the spring sheet 19 is arc-shaped and deviates to one side, and the air suction hole 8 is located on the inner side of the deviated direction of the spring sheet 19. When the second grinding part 3 shown in the figure rotates clockwise, it can just cover the ground dust, thereby facilitating the suction of the air suction hole 8. Alternatively, the spring sheet 19 can also be used Fig.16 In the structure shown in , the rotation direction of the second grinding part 3 is still as shown by the arrow in the figure. In this structure, the bending structure at the end of the spring sheet 19 can better increase its elastic range of activity, thereby taking into account the contact process with more steel beams of different sizes;

[0070] Further, see Figure 4 Regarding the communication mode between the storage chamber 7 and the guide chamber 9, specifically, a guide area 10 is constructed in the support portion 4, which is connected to the guide chamber 9, and the pneumatic motor 6 is a vane-type pneumatic motor 6, and its output shaft is a hollow structure, and its two ends extend into the storage chamber 7 and the guide area 10 respectively, so that dust can pass through the inner shaft of the pneumatic motor 6;

[0071] Further, see Figure 1 and Figure 2 A delivery tube 11 is connected between the support portion 4 and the base 101, and the guide area 10 and the guide cavity 9 are communicated with each other through the delivery tube 11. In addition, the delivery tube 11 is an elastic structure to satisfy the elastic reset relationship of the support portion 4 on the base 101. For example, the delivery tube 11 can be an elastic tube with a PU structure;

[0072] Example 2

[0073] Reference Fig.14 and Fig.15 , which is the second embodiment of the present invention, and this embodiment provides a steel structure building paint repair device, which is a further technical upgrade based on the first embodiment. Specifically, as shown in the figure, a steel structure building paint repair device includes the rust removal device in the first embodiment, and also includes a jet component configured to move synchronously with the base 101, and a third pipeline 26. The jet component can be an atomizing jet nozzle 25, which faces the surface of the steel beam and is arranged on the rear side of the moving direction of the moving part 1. In terms of the air path relationship, the airflow will pass through the jet nozzle 25 after flowing out from the pneumatic motor 6, and finally be discharged. The third pipeline 26 (oil pipe) is connected to The first pipeline 22 is parallel, and the air nozzle 25 is used to be connected to a paint source (a paint can or a paint bucket or other container) on the ground through an oil pipe. The paint source is provided with a delivery pump for delivering the paint into the air nozzle 25. At the same time, the airflow enters the air nozzle 25 and mixes with the paint, so that the paint forms a high-pressure state so that it can be sprayed. In this way, the present invention can automatically touch up the rust-removed steel beam surface in the process of grinding and rust removal while moving, thereby further expanding the actual use effect of the present invention, and further increasing the replacement effect of manual labor in the entire steel beam rust removal and jetting process, thereby improving the efficiency of the operation.

[0074] It will be appreciated that in the development of any actual implementation, as in any engineering or design project, numerous implementation-specific decisions may be made.
