Description
Technical Field
[0001] The utility model relates to the technical field of steel structure shot blasting, in particular to an elevated steel structure hanging chain type shot blasting device. Background Art
[0002] Elevated steel structure refers to an overhead building or structure that uses steel as the main load-bearing structure, including steel sections, steel plates, steel pipes, steel bars, etc. Elevated steel structures have high strength and toughness and can withstand large loads. They are usually used in infrastructure such as highways, urban expressways, rail transit, and pedestrian bridges. Elevated steel is an indispensable material in modern infrastructure construction. Its performance and quality are directly related to the overall performance and safety of the elevated structure.
[0003] However, during the production and storage process, existing elevated steel structures will form a layer of oxide scale on their surface, and they will also rust due to exposure to humid environments. Shot blasting can effectively remove these oxides and rust, providing a clean base surface for subsequent coating. Existing shot blasting equipment is equipped with a hanger for hoisting the elevated steel structure and transporting it to the shot blasting box. The hanger is equipped with a wire rope and a hook. The elevated steel structure is tied with an iron chain and then hung on the hook by the iron chain, making it easy to lift the elevated steel structure and transport it to the shot blasting box for shot blasting. However, multiple elevated steel structures are hung on a hook and placed close together. There is no gap between the multiple elevated steel structures, resulting in uneven shot blasting of the multiple elevated steel structures. They need to be repeatedly adjusted, which reduces the shot blasting efficiency. In addition, the debris and impurities generated by the shot blasting of the elevated steel structures fall to the bottom of the box and mix with the shot. They need to be cleaned out and screened by a screening machine to separate the shot. The shot is reused repeatedly, which increases the workload and is time-consuming and labor-intensive.

[0024] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making any creative work shall fall within the scope of protection of the present application.
[0025] The embodiment of the utility model provides an elevated steel structure hanging chain type shot blasting device, which can realize that multiple elevated steel structures can be hung separately on hooks through a lifting component, so that the multiple elevated steel structures will not be close to each other. When the elevated steel structure is shot blasted with projectiles, it can ensure that the surface of the elevated steel structure is evenly shot blasted, and there is no need to move the elevated steel structure out of the shot blasting box for adjustment, thereby improving the efficiency of the shot blasting of the elevated steel structure. The cleaning component can speed up the screening speed between debris and impurities and projectiles on the steel screen plate, making it easy to separate debris and impurities from the projectiles. When collecting the projectiles, they can be directly taken out from the steel screen plate, thereby achieving the purpose of saving time and effort and reducing the workload of workers.
[0026] The present application is described in detail below with reference to the accompanying drawings and specific implementation methods. Example
[0027] like Figure 1-Figure 7 As shown, an elevated steel structure chain-type shot blasting device, a shot blasting box 1, a hanger 101 installed on the top of the shot blasting box 1, a movable slot 102 opened in the middle of the top of the shot blasting box 1, a hanging assembly arranged at the bottom of the hanger 101, the hanging assembly including: a hanging rod 103, a fixed plate 104, a steel wire rope 105, a hanging plate 106 and a hook 108, a cleaning assembly arranged at the bottom end of the shot blasting box 1, the cleaning assembly including: a steel screen plate 5, a guide plate 501, a rotating motor 502, a motor shaft 503 and a cam 504.
[0028] Among them, a forward and reverse motor 2 is installed at the bottom of the hanger 101, and a limit plate 201 is installed on the other side of the bottom of the hanger 101. One end of the forward and reverse motor 2 is driven and connected to a reciprocating screw rod 202, and the other end of the reciprocating screw rod 202 is rotatably connected to the limit plate 201 through a bearing. A moving head 203 is provided on the reciprocating screw rod 202, and a screw hole threadedly connected to the reciprocating screw rod 202 is opened inside the moving head 203, and the bottom of the moving head 203 is fixedly connected to the hanger 103.
[0029] When the elevated steel structure is shot blasted, the door of the shot blasting box 1 is first opened, and the forward and reverse motors 2 are started to drive the reciprocating screw 202 to rotate. The moving head 203 is threadedly rotated with the reciprocating screw 202 through the screw hole, so that the moving head 203 can move back and forth on the reciprocating screw 202, that is, the moving head 203 can drive the suspension rod 103, the fixed plate 104, the wire rope 105, the hanging plate 106 and the hook 108 to move back and forth, so as to facilitate the removal of the hanging plate 106 and the hook 108 from the inside of the shot blasting box 1. After the elevated steel structure is respectively hung on the hook 108, the hanging plate 106 and the hook 108 are driven by the moving head 203 to move back to the inside of the shot blasting box 1, and the elevated steel structure can be loaded and unloaded.
[0030] Among them, a hanging rod 103 is provided at the bottom of the hanger 101, a fixed plate 104 is installed at the bottom of the hanging rod 103, a steel wire rope 105 is provided at the bottom of the fixed plate 104, a lifting plate 106 is provided at the bottom of the steel wire rope 105, a plurality of hooks 108 are fixedly installed at the bottom of the lifting plate 106 by bolts, two lifting rings 107 are fixedly installed on the top of the lifting plate 106, the two lifting rings 107 are fixedly connected with one end of the steel wire rope 105 by winding, and a lifting cylinder 3 is installed on both sides of the top of the fixed plate 104. The bottom of the lifting cylinder 3 is driven and connected with a telescopic rod 301. The bottom of the telescopic rod 301 is rotatably connected to a connecting head 302 through a bearing. A connecting hole 303 is opened on the outside of the connecting head 302, and the other end of the steel wire rope 105 is fixedly connected with the connecting hole 303 by winding.
[0031] After the moving head 203 drives the lifting plate 106 and the hook 108 to move out of the shot blasting box 1, the lifting cylinder 3 is started to drive the telescopic rod 301 to move downward, and the telescopic rod 301 drives the wire rope 105, the lifting plate 106 and the hook 108 to move downward, so that the hook 108 can be close to the elevated steel structure placed on the ground. Since the elevated steel structure is fixed by an iron chain, the iron chain can be directly hung on the hook 108, and a plurality of hooks 108 are fixedly installed on the bottom of the lifting plate 106 by bolts. Multiple elevated steel structures can be hung separately on the hooks 108, so that the multiple elevated steel structures will not be close to each other. When the elevated steel structure is shot blasted with projectiles, it can ensure that the surface of the elevated steel structure is shot blasted evenly, and there is no need to move the elevated steel structure out of the shot blasting box 1 for adjustment, thereby improving the efficiency of the shot blasting of the elevated steel structure.
[0032] Among them, shot blasting machines 4 are installed on both sides of the outer end of the shot blasting box 1, and a shot blasting wheel 401 is installed on the outer end of the shot blasting machine 4. The shot blasting wheel 401 consists of a motor, a casing, an impeller, a feeding pipe and a loading hopper. A shot blasting pipe mouth 402 connected to the shot blasting machine 4 is installed on the inner side of the shot blasting machine 4.
[0033] After the multiple hooks 108 are hung on the elevated steel structure, the telescopic rod 301 drives the wire rope 105, the hoisting plate 106, the hook 108 and the elevated steel structure to move upward, and the moving head 203 drives the wire rope 105, the hoisting plate 106 and the hook 108 to move into the shot blasting box 1. The wire rope 105 and the telescopic rod 301 can move inside the moving groove 102, and then the elevated steel structure is sent into the shot blasting box 1 so that the elevated steel structure is facing the shot blasting nozzle 402. The box door is closed and the projectiles are placed. The pellets are fed into the loading hopper and discharged into the casing through the feeding pipe. The motor is started to drive the impeller to project the pellets from the shot blasting nozzle 402 to the surface of the elevated steel structure, thereby completing the shot blasting process on the elevated steel structure. When the pellets are projected onto the elevated steel structure, the elevated steel structure is subjected to force. Since the bottom of the telescopic rod 301 is rotatably connected to the connector 302 through a bearing, and the connector 302 is connected to the wire rope 105, the elevated steel structure will rotate after being impacted by the elastic force, thereby allowing shot blasting to be performed on different surfaces of the elevated steel structure.
[0034] Among them, a steel sieve plate 5 is installed at the bottom end of the shot blasting box 1, and guide plates 501 are installed between both ends of the steel sieve plate 5 and the inner wall of the shot blasting box 1.

A cam 504 is provided at one end of the motor shaft 503. One end of the motor shaft 503 passes through the guide plate 501 and is connected to the cam 504. The top of the cam 504 fits with the bottom of the steel sieve plate 5.
[0035] During the shot blasting process of the elevated steel structure, the debris, impurities and projectiles generated therein will fall onto the steel sieve plate 5 together. Since the steel sieve plate 5 is connected to the collection box 6, the debris and impurities on the steel sieve plate 5 will fall into the collection box 6 for collection. At this time, the rotating motor 502 is started to drive the motor shaft 503 to rotate, and the motor shaft 503 drives the cam 504 to rotate, so that the cam 504 strikes the steel sieve plate 5, which can speed up the screening speed between the debris and impurities and the projectiles on the steel sieve plate 5, making it easier to separate the debris and impurities from the projectiles. When collecting the projectiles, they can be taken out directly from the steel sieve plate 5, thereby saving time and effort and reducing the workload of workers.
[0036] Among them, a collecting box 6 connected to the steel screen plate 5 is installed at the bottom end of the shot blasting box 1, a push plate 601 is provided on one side of the inside of the collecting box 6, and a baffle 602 is connected to the outside of the collecting box 6 by a hinge. An electric push rod 603 is installed at the outer end of the collecting box 6, and a through hole 604 is opened on the outside of the collecting box 6, and the electric push rod 603 passes through the through hole 604 and is connected to the push plate 601.
[0037] After the debris and impurities on the steel sieve plate 5 are cleaned and fall into the collection box 6 for collection, the baffle 602 is opened and the electric push rod 603 is started to push the push plate 601 to move inside the collection box 6 to clean out the debris and impurities inside the collection box 6 to avoid accumulation and blockage inside the collection box 6.
[0038] Among them, a control chassis is fixedly installed on the outer end of the shot blasting box 1, and multiple control buttons are installed on the outside of the control chassis, and a power cord is installed on the back of the control chassis. The forward and reverse motor 2, lifting cylinder 3, shot blasting machine 4, rotating motor 502 and electric push rod 603 are connected to the control chassis through wires. The power cord is 3 meters long, and a plug is installed on the other end of the power cord. The plug can be inserted into an indoor socket to turn on the power, so that the control chassis, forward and reverse motor 2, lifting cylinder 3, shot blasting machine 4, rotating motor 502 and electric push rod 603 are powered on and used normally. The control chassis can control the start and stop of the forward and reverse motor 2, lifting cylinder 3, shot blasting machine 4, rotating motor 502 and electric push rod 603, and the control procedures involved in the present invention can be implemented by those skilled in the art according to the same or similar principles in the prior art. This part is not the innovation of the present utility model.
