Description

Technical Field

[0001] The utility model relates to the technical field of shot blasting equipment, in particular to a steel structure shot blasting device which is convenient for feeding and discharging materials. Background Art

[0002] In the process of processing steel structure, in order to remove the surface oxide layer and impurities to improve the appearance quality, it is necessary to use a shot blasting machine to perform shot blasting on the steel structure. During the shot blasting, the high-speed moving projectiles continuously impact the surface of the workpiece to achieve a cleaning effect. Traditional shot blasting devices generally include a shot blasting machine and a carrier that cooperates with it. When in use, the steel structure is placed on the carrier, and then the carrier is pushed into the shot blasting machine. In the shot blasting device of this structure, the surface of the steel structure close to the carrier cannot be fully shot blasted, resulting in poor surface treatment effect of the workpiece. In order to solve this problem, hanging shot blasting devices have gradually appeared on the market. For example, a steel structure component steel sand grinding shot blasting machine disclosed in the Chinese patent document with publication number CN218856652U has a through slot on the top of the shot blasting machine body for the suspension rod to pass through, and then the two movable baffles are arranged by using the movable baffle, the adjustment mechanism and the synchronization mechanism so that the two movable baffles can move relative to or opposite to each other, so that the through slot can be blocked when the shot blasting machine body is working. This solution hoists the steel structure components inside the shot blasting machine to achieve a full range of shot blasting effects. However, in actual operation, the user needs to move the boom to align with the bayonet before controlling the servo motor to move, thereby prompting the movable baffle to move to block the through slot. The alignment of the boom and the bayonet needs to be manually observed, which consumes a lot of workers' energy and is not conducive to the rapid movement of the boom into position. Utility Model Content

[0003] The technical problem to be solved by the utility model is that in the prior art, the operation of the shot blasting machine is relatively complicated, requires a lot of manpower, and is not conducive to material loading and unloading. In view of this, the utility model provides a steel structure shot blasting device with a high degree of automation and convenient material loading and unloading.

[0004] The utility model solves the technical problem by adopting the following technical solution: a steel structure shot blasting device with convenient feeding and discharging, comprising a shot blasting machine body and a suspension device, wherein the top wall of the shot blasting machine body is provided with an avoidance groove, and further comprising a blocking component and a controller, wherein the suspension device comprises a rope movable along the avoidance groove and used for hooking the steel structure, wherein the blocking component comprises a baffle plate located on one side of the avoidance groove, an electromagnet arranged on one side of the baffle plate, and an elastic member, wherein the baffle plate is slidably connected to the shot blasting machine body, the electromagnet is fixedly connected to the shot blasting machine body, a magnetic member is connected to the baffle plate, the elastic member is elastically supported between the electromagnet and the magnetic member, a pressure sensor is provided at the end of the avoidance groove, and the pressure sensor and the electromagnet are both electrically connected to the controller.

DETAILED DESCRIPTION

[0021] Now the utility model is described in detail with reference to the accompanying drawings. This figure is a simplified schematic diagram, which only illustrates the basic structure of the utility model in a schematic manner, so it only shows the components related to the utility model.

[0022] See also Figure 1-Figure 4 The utility model provides a steel structure shot blasting device with convenient feeding and discharging, including a shot blasting machine body 10 and a suspension device 20. The front side of the shot blasting machine body 10 is provided with an openable and closable switch door 11, and the switch door 11 can be connected to the shot blasting machine body 10 in a hinged manner. The top wall of the shot blasting machine body 10 is provided with an avoidance groove 12. The suspension device 20 includes a rope 21 for hooking the steel structure. The steel rope 21 can enter the avoidance groove 12 from the front side of the shot blasting machine body 10. A blocking component 30 is installed on one side of the avoidance groove 12 on the top wall of the machine body 10. The blocking component 30 has a blocking state and an open state. When the blocking component 30 is in the blocking state, the avoidance groove 12 is blocked. At this time, the shot blasting machine body 10 can shot blast the steel structure hooked on the rope 21; when the blocking component 30 is in the open state, the avoidance groove 12 is opened. At this time, the rope 21 hooked with the steel structure can enter and exit the avoidance groove 12, which is convenient for loading and unloading.

[0023] The blocking assembly 30 includes a baffle 31, an electromagnet 32 ​​and an elastic member 33. The baffle 31 is located on one side of the avoidance groove 12. The baffle 31 is slidably disposed on the top wall of the shot blasting machine body 10. The electromagnet 32 ​​is fixedly installed on the top wall of the shot blasting machine body 10, and the electromagnet 32 ​​is located on the side of the baffle 31 away from the avoidance groove 12. A magnetic member 34 is fixedly connected to the side of the baffle 31 close to the electromagnet 32. The magnetic member 34 has ferromagnetism. The elastic member 33 elastically abuts between the electromagnet 32 ​​and the magnetic member 34. A pressure sensor 35 is installed at the end of the avoidance groove 12. The steel structure shot blasting device for convenient feeding and discharging of the utility model also includes a controller 36. The controller 36 is installed on the shot blasting machine body 10. The pressure sensor 35 and the electromagnet 32 ​​are electrically connected to the controller 36.

[0024] When feeding, the electromagnet 32 ​​is in an energized state, and the magnetic force generated by the electromagnet 32 ​​attracts the magnetic attraction member 34, driving the baffle 31 to move in the direction close to the electromagnet 32, thereby opening the avoidance groove 12. At this time, the user operates the suspension device 20 through the driving to make the rope 21 hooked with the steel structure enter the avoidance groove 12 from the front side of the shot blasting machine body 10, and gradually extends the rope 21 inward along the length direction of the avoidance groove 12 until the rope 21 and the pressure sensor 35 at the end of the avoidance groove 12 are in contact. When the pressure sensor 35 detects that the pressure of the rope 21 on it reaches a preset value, the signal is transmitted to the controller 36. After receiving the signal, the controller 36 controls the electromagnet 32 ​​to lose power. After the electromagnet 32 ​​loses power, the magnetism disappears, and the baffle 31 moves in the direction away from the electromagnet 32 ​​under the elastic force of the elastic member 33, and finally covers the upper part of the avoidance groove 12, effectively preventing the internal projectiles from flying out of the shot blasting machine body 10 when the shot blasting machine body 10 is working.

[0025] After the shot blasting is completed, the user moves the rope 21 in the opposite direction of the avoidance groove 12, and the rope 21 is separated from the pressure sensor 35. When the pressure sensor 35 detects that the pressure of the rope 21 on it disappears, it will transmit the signal to the controller 36. After receiving the signal, the controller 36 controls the electromagnet 32 ​​to be energized. After the electromagnet 32 ​​is energized, it generates magnetic force, which can overcome the elastic force of the elastic member 33 to attract the magnetic member 34 together with the baffle 31, and then open the avoidance groove 12, so as to move the rope 21 out of the avoidance groove 12. It should be noted that when the baffle 31 blocks the avoidance groove 12, there is a space between the baffle 31 and the rope 21 for the rope 21 to retreat, so that the rope 21 can retreat and then separate from the pressure sensor 35.

[0026] In this embodiment, the baffle 31 is made of polytetrafluoroethylene material, which has a low friction coefficient and good wear resistance, and is light in weight, and can ensure that the baffle 31 slides smoothly relative to the shot blasting machine body 10. In addition, the material has high structural strength and can effectively resist high-speed impact of projectiles.

[0027] Furthermore, the magnetic attraction member 34 is made of a ferromagnetic metal material such as iron or nickel.

[0028] As a preferred embodiment, two oppositely disposed baffles 13 are fixedly mounted on the top wall of the shot blasting machine body 10, and a baffle plate 31 is slidably disposed between the two baffle plates 13, and opposite side walls of the baffle plate 31 are respectively in contact with the baffle plates 13, wherein the sliding direction of the baffle plate 31 is perpendicular to the extending direction of the avoidance groove 12. The baffle plates 13 limit the movement of the baffle plate 31 in the horizontal direction.

[0029] Furthermore, a limit strip 14 is fixedly connected to the side walls opposite to each other on the two baffles 13, and the limit strip 14 is arranged along the length direction of the baffle 13. The lower surface of the limit strip 14 fits with the upper surface of the baffle 31, so that the baffle 31 cannot move longitudinally, thereby ensuring the activity stability of the baffle 31.

[0030] As a preferred embodiment, a positioning block 15 is fixedly connected to the top wall of the shot blasting machine body 10 on the side of the avoidance groove 12 away from the baffle 13, and a positioning protrusion 16 is fixedly connected to the side wall of the baffle 13. The two opposite sides of the baffle 31 can respectively abut against the positioning block 15 and the positioning protrusion 16. When the baffle 31 gradually blocks the avoidance groove 12 under the push of the elastic member 33 until it abuts against the positioning block 15, the avoidance groove 12 is blocked, and the blocking component 30 is in a blocked state at this time; when the baffle 31 moves under the magnetic action of the electromagnet 32 ​​and abuts against the positioning protrusion 16, the avoidance groove 12 is fully opened, and the blocking component 30 is in an open state at this time.

[0031] One end of the elastic member 33 is fixedly connected to the electromagnet 32, and the other end of the elastic member 33 is fixedly connected to the magnetic member 34. In order to ensure the smooth movement of the baffle 31, there are two elastic members 33, and the two elastic members 33 are symmetrically arranged. In addition, in this embodiment, the elastic member 33 is a spring.

[0032] The utility model provides a steel structure shot blasting device which is convenient for loading and unloading materials. When the user manipulates the rope 21 to extend into the avoidance groove 12 until the rope 21 abuts against the pressure sensor 35, the controller 36 controls the electromagnet 32 ​​to lose power, so that the baffle 31 blocks the avoidance groove 12 under the elastic force of the elastic member 33. When the rope 21 moves outward, the controller 36 controls the electromagnet 32 ​​to be energized, so that the baffle 31 is magnetically adsorbed to open the avoidance groove 12, so as to facilitate the removal of the rope 21. Compared with the prior art, the utility model has a high degree of automation, which greatly reduces the labor of the user and is beneficial to loading and unloading materials.

[0033] Based on the above ideal embodiments of the utility model, the relevant staff can make various changes and modifications without departing from the scope of the utility model through the above description. The technical scope of this utility model is not limited to the contents of the specification, and its technical scope must be determined according to the scope of the claims.
