[0015] A method for using a construction engineering steel structure component transfer device comprises the following steps:

[0016] Before the steel structure member is placed, the top plate (5) is in a dismantled state, and the side plate (24) is rotated to the lowest point;

[0017] When placing the steel structure components, the operator can place the steel structure components directly onto the bottom bracket (1) through the vertical surface formed by the vertical pipe (2) and the horizontal pipe (3), and then continuously stack the steel structure components. When the top of the stacked steel structure components is almost flush with the horizontal pipe (3), stop placing the steel structure components.

[0018] Subsequently, the top plate (5) is placed on the transverse tube (3) to ensure that the pressure tube (27) is inserted into the connecting hole (28). Then, the top plate (5) is pressed downward to achieve contact between the bottom surface of the top plate (5) and the top surface of the connecting piece (4). When the top plate (5) is pressed downward, the inclined surface at the bottom end of the positioning block (6) contacts the locking head (12), pushing the locking head (12) out of the connecting box (8). At this time, the return spring (11) is in a stretched state, and a pulling force is applied to the locking rod (9) through the connecting plate (10), so that the locking head (12) is always in contact with the positioning block (6). When the locking groove (7) and the locking head ( After the locking head (12) is aligned, the elastic force of the return spring (11) can clamp the locking head (12) in the locking groove (7), thereby fixing the position of the top plate (5). During the movement of the locking head (12), the locking rod (9) drives the moving plate (14) to move toward the center of the three-way pipe (13), thereby squeezing the air in the three-way pipe (13) to push the starting rod (17) downward, so that the starting rod (17) presses the switch on the air pump (16), starts the air pump (16), and draws external air into the cross pipe (3) through the air inlet pipe (18), and then passes through the cross pipe (3), the connecting piece (4) and The vertical pipe (2) first enters the connecting groove (19), and then enters the installation groove (20) through the connecting groove (19). As the air continues to enter, the pressure in the installation groove (20) continues to increase, and then the rack (21) can be pushed outward. Through the meshing of the rack (21) and the gear (25), the side plate (24) is driven to rotate upward. When the side plate (24) contacts the connecting piece (4), the side plate (24) cannot move further. At this time, the rack (21) cannot move either. The pressure in the horizontal pipe (3) continues to increase. When it reaches the opening pressure of the pressure pipe 1 (27), the air passes through the horizontal pipe. (3) and the pressure tube 1 (27) enter the airbag (26), so that the airbag (26) is inflated and expanded downward to contact the steel structure. When the airbag (26) can no longer expand, the pressure in the cross tube (3) continues to increase. When the opening pressure of the pressure tube 2 (29) is reached, air enters the pressure tube 2 (29), pushes the push rod (30) out and squeezes the return spring 3 (31). When the push rod (30) is pushed out, it contacts the trigger rod (173), thereby pushing the trigger rod (173) forward, so that the trigger rod (173) leaves the switch of the air pump (16), and the air pump (16) stops.

[0019] Then, the device is lifted up through the movable groove opened at the bottom of the bottom bracket (1) by using a lifting tool and transported to a storage place. When the steel structure component is needed, the bottom bracket (1) is transported to the required place, the top plate (5) is opened upward, the positioning block (6) is taken out of the connection box (8), and the pressure tube (27) is separated from the connection hole (28). At this time, the locking head (12) loses its obstruction and is completely reset under the elastic action of the reset spring (11), so that the movable plate (14) moves in the opposite direction, increasing the space inside the three-way pipe (13), thereby pulling up the start rod (17), and because the connection hole (28) loses the seal of the pressure tube (27), the gas in the cross tube (3) is directly discharged through the connection hole (28), and then the air bag (26) is deflated, and then the pressure relief valve (32) is closed. ) is opened to discharge the air in the pressure tube 2 (29), so that the push rod (30) is reset under the elastic action of the reset spring 3 (31), and the trigger rod (173) is swung downward and reset under the action of gravity and is adsorbed on the bottom of the lifting rod (171). In this process, the reset spring 2 (23) in a compressed state pulls the rack (21) back under the action of elasticity, so that the side plate (24) rotates downward. The damping rod (33) is provided to slow down the reverse movement of the rack (21) to achieve the effect of slowing down the falling speed of the side plate (24). When the side plate (24) is fully opened, the steel structure component can be taken out from the side of the vertical tube (2) and the horizontal tube (3), or the steel structure component can be taken out by directly tilting the device to make the steel structure component slide out completely.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. The present invention is such that when the top plate (5) is covered on the horizontal tube (3), the downward movement of the positioning block (6) drives the fixed component to move for positioning, and the switch on the air pump (16) is turned on through the conduction of the trigger component, and then the horizontal tube (3) is inflated by the air pump (16), so that the air enters the connecting groove (19) and the mounting groove (20) through the horizontal tube (3) and the vertical tube (2) to push the rack (21) outward, and then the side plate (24) is driven to rotate upward through the gear (25) to close the four sides of the vertical tube (2), so that when placing or removing the steel structure component, the steel structure component can be placed or removed directly from the side, without the need for the operator to repeatedly bend over to operate, thereby reducing the labor burden of the operator.

[0022] 2. The present invention arranges an airbag (26) under the top plate (5) and after the side plate (24) closes the side of the vertical pipe (2), air enters the air passage in the top plate (5) through the pressure pipe 1 (27) and then enters the airbag (26), so that the airbag (26) expands downward and contacts the steel structure component. Since a layer of flexible metal mesh composed of steel wire ropes is attached to the bottom surface of the airbag (26), scratches and damages of the airbag (26) can be avoided, thereby achieving the effect of squeezing the steel structure component, avoiding the shaking of the steel structure component during transportation, and reducing the damage of the steel structure component caused by shaking during transportation.

[0023] 3. The present invention provides a damping rod (33) on the extension rod (22), so that the movement speed of the rack (21) can be slowed down by the damping effect of the damping rod (33) itself, so that the side plate (24) can be slowly raised and lowered, thereby avoiding potential safety hazards. At the same time, the unevenly stacked steel structure components can be completely pushed onto the bottom bracket (1) by the slowly moving side plate (24), thereby arranging the steel structure components and preventing the device from being damaged by impact.

DETAILED DESCRIPTION

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] like Figures 1 to 10 As shown, the present invention provides a transport device for steel structure components of construction engineering, comprising a bottom bracket 1, vertical pipes 2 are plugged into the four corners of the top of the bottom bracket 1, a connector 4 is plugged into the top of the vertical pipe 2, horizontal pipes 3 are plugged into the two sides of the connector 4, and a top plate 5 is provided above the horizontal pipe 3;

[0038] The four sides of the top of the bottom bracket 1 are rotatably connected to the side plates 24, and the bottom end of the side plates 24 is fixedly installed with a gear 25;

[0039] When the top plate 5 is covered on the transverse tube 3, the downward movement of the positioning block 6 pushes the fixing assembly to move for positioning, and the switch on the air pump 16 is opened through the conduction of the trigger assembly, and then the transverse tube 3 is filled with gas through the air pump 16, so that the air enters the connecting groove 19 and the mounting groove 20 through the transverse tube 3 and the vertical tube 2, pushing the rack 21 to extend outward, and then the side plate 24 is driven by the gear 25 to rotate upward to close the vertical tube 2 on all sides. When it is necessary to remove the steel structure component, it is only necessary to remove the top plate 5, so that the air in the vertical tube 2 and the transverse tube 3 can flow out from the connecting hole 28, realize the reverse movement of the rack 21, and open the side plate 24, so that when placing and removing the steel structure components, the steel structure components can be placed or removed directly from the side, without the need for the operator to repeatedly bend over to operate, thereby reducing the labor burden of the operator.

[0040] The fixing assembly includes a locking rod 9, which is movably connected in the transverse tube 3, a connecting plate 10 is fixedly installed on the surface of the locking rod 9, a return spring 11 is sleeved on the surface of the locking rod 9, a locking head 12 is fixedly installed on one end of the locking rod 9 close to the connection box 8, a locking groove 7 is opened on one side of the positioning block 6 close to the locking rod 9, and the locking head 12 is inserted into the locking groove 7;

[0041] When the top plate 5 is pressed down, the inclined surface at the bottom end of the positioning block 6 contacts the locking head 12, pushing the locking head 12 out of the connecting box 8. At this time, the reset spring 11 is in a stretched state, and a pulling force is applied to the locking rod 9 through the connecting plate 10, so that the locking head 12 is always in contact with the positioning block 6. When the locking groove 7 and the locking head 12 are aligned, the elastic force of the reset spring 11 can clamp the locking head 12 in the locking groove 7, thereby fixing the position of the top plate 5, thereby locking the top plate 5 and the connecting piece 4, avoiding accidental falling off of the top plate 5 during transportation, and transmitting power to the moving sheet 14.

[0042] The trigger assembly includes a three-way pipe 13, which is fixedly installed on the right side of the inner cavity of the transverse pipe 3. The bottom end of the transverse pipe 3 is movably connected with a starter rod 17. The front and rear ends of the three-way pipe 13 are fixedly installed with moving pieces 14. There are two moving pieces 14 in total, and the two moving pieces 14 are fixedly connected to the locking rod 9.

[0043] During the movement of the locking head 12, the locking rod 9 drives the moving piece 14 to move toward the center of the three-way pipe 13, and then squeezes the air in the three-way pipe 13 to push the starting rod 17 downward, so that the starting rod 17 presses the switch on the air pump 16, starts the air pump 16, and draws external air into the cross pipe 3 through the intake pipe 18, so as to start the air pump 16. When the trigger rod 173 is pushed open, the switch of the air pump 16 is released, so that the air pump 16 is automatically shut down.

[0044] The driving assembly includes a rack 21, which is slidably connected in the mounting groove 20, an extension rod 22 is fixedly installed on the surface of the rack 21, and a return spring 23 is fixedly installed on one end of the extension rod 22 away from the rack 21. The cross section of the rack 21 is consistent with the cross section of the mounting groove 20 and is equal in size, and the rack 21 is meshed with the gear 25;

[0045] It first enters the connecting groove 19 through the horizontal pipe 3, the connecting piece 4 and the vertical pipe 2, and then enters the installation groove 20 through the connecting groove 19. As air continues to enter, the pressure in the installation groove 20 continues to increase, and then the rack 21 can be pushed outward. Through the engagement of the rack 21 and the gear 25, the side plate 24 is driven to rotate upward, and the rack 21 slides in the installation groove 20, and the installation groove 20 is directly sealed by the rack 21.

[0046] The height of the connection box 8 is equal to half of the height of the inner cavity of the horizontal tube 3. The connection between the bottom bracket 1, the vertical tube 2, the horizontal tube 3 and the connection piece 4 is fixed by a pin and sealed with a sealing ring. The locking rod 9 is located above the pin. The connection groove 19, the vertical tube 2, the horizontal tube 3 and the connection piece 4 are connected.

[0047] To prevent the gas in the cross tube 3 from being blocked by the connection box 8 and to prevent the locking rod 9 from interfering with the pin and causing the installation to fail, the sealing ring used needs to ensure that the device is leak-proof.

[0048] Among them, an air bag 26 is fixedly installed on the bottom surface of the top plate 5, and pressure tubes 27 are fixedly installed on both the front and rear sides of the bottom surface of the top plate 5. An airway is opened in the middle of the top plate 5, and the airway connects the two pressure tubes 27. Connection holes 28 are opened at the front and rear ends of the cross tube 3. The pressure tube 27 is inserted into the connection hole 28 and communicates with the inner cavity of the cross tube 3.

[0049] There are two layers at the bottom end of the airbag 26, one layer of airtight cloth is placed on top to achieve expansion, and the bottom end is a flexible metal mesh woven with steel wire ropes, which is used to separate the cloth and the steel structure components, and the two are pasted together. By arranging the airbag 26 under the top plate 5 and closing the side of the vertical pipe 2 on the side plate 24, the air enters the airway in the top plate 5 through the pressure pipe 27 and then enters the airbag 26, so that the airbag 26 expands downward and contacts the steel structure components. Since a layer of flexible metal mesh composed of steel wire ropes is pasted on the bottom surface of the airbag 26, scratches and damages of the airbag 26 can be avoided, thereby achieving the effect of squeezing the steel structure components, avoiding the shaking of the steel structure components during transportation, and reducing the damage to the steel structure components caused by shaking during transportation.

[0050] Among them, a pressure tube 29 is fixedly installed on the right side of the horizontal tube 3, and a push rod 30 is slidably connected to the bottom end of the pressure tube 29. A return spring 31 is sleeved on the surface of the push rod 30. A pressure relief valve 32 is fixedly installed in the middle of the pressure tube 29. The starting rod 17 includes a lifting rod 171, which is movably connected to the bottom end of the three-way pipe 13. The bottom end of the lifting rod 171 is rotatably connected to a connecting piece 172, and a trigger rod 173 is fixedly installed at the bottom end of the connecting piece 172. The trigger rod 173 is magnetically connected to the lifting rod 171. A clearance groove 174 is opened on the front side of the bottom end of the lifting rod 171. The front end of the push rod 30 passes through and extends to the front side of the pressure tube 29. The push rod 30 is located at the rear side of the trigger rod 173, and the axes of the push rod 30 and the trigger rod 173 are on the same vertical plane.

[0051] The magnetic connection between the lifting rod 171 and the trigger rod 173 can ensure that when the reset spring three 31 does not contact the trigger rod 173, the trigger rod 173 can be adsorbed on the bottom end of the lifting rod 171 and remain vertical, and the clearance groove 174 is provided to provide a movable space for the trigger rod 173. After the pressure in the cross tube 3 continues to increase to the opening pressure of the pressure tube one 27, the air enters the airbag 26 through the cross tube 3 and the pressure tube one 27, so that the airbag 26 is inflated and expanded downward to contact the steel structure. When the airbag 26 can no longer expand, the pressure in the cross tube 3 continues to increase. When the opening pressure of the pressure tube two 29 is reached, the air enters the pressure tube two 29, pushes the push rod 30 out and squeezes the reset spring three 31. When the push rod 30 is pushed out, it contacts the trigger rod 173, and then pushes the trigger rod 173 forward, so that the trigger rod 173 leaves the switch of the air pump 16, and the air pump 16 stops.

[0052] Among them, a return spring 23 is fixedly installed on one end of the extension rod 22 away from the rack 21, and the other end of the return spring 23 is fixed on the inner wall of the installation groove 20;

[0053] When placing steel structure components, whether they are stacked manually or mechanically, it is inevitable that the ends of some steel structure components will extend out of the vertical pipe 2. By arranging a damping rod 33 on the extension rod 22, the damping effect of the damping rod 33 itself can be used to slow down the movement speed of the rack 21, so that the side plate 24 can be slowly raised and lowered, avoiding safety hazards. At the same time, the unevenly stacked steel structure components can be completely pushed onto the bottom bracket 1 by the slowly moving side plate 24, so as to tidy up the steel structure components while avoiding impact damage to the device.

[0054] A method for using a construction engineering steel structure component transfer device comprises the following steps:

[0055] Before the steel structure components are placed, the top plate 5 is in a dismantled state, and the side plate 24 is rotated to the lowest point;

[0056] When placing the steel structure components, the operator can place the steel structure components directly on the bottom bracket 1 through the vertical surface formed by the vertical pipe 2 and the horizontal pipe 3, and then continuously stack the steel structure components. When the top of the stacked steel structure components is almost flush with the horizontal pipe 3, stop placing the steel structure components;

[0057] Then, cover the top plate 5 on the cross tube 3, ensure that the pressure tube 27 is inserted into the connecting hole 28, and then press the top plate 5 downward to achieve the bottom surface of the top plate 5 in contact with the top surface of the connecting piece 4. When the top plate 5 is pressed down, the inclined surface at the bottom end of the positioning block 6 contacts the locking head 12, and the locking head 12 is pushed out of the connecting box 8. At this time, the reset spring 11 is in a stretched state, and a pulling force is applied to the locking rod 9 through the connecting plate 10, so that the locking head 12 is always in contact with the positioning block 6. When the locking groove 7 and the locking head 12 are aligned After that, the elastic force of the return spring 11 can clamp the locking head 12 in the locking groove 7, thereby fixing the position of the top plate 5. During the movement of the locking head 12, the locking rod 9 drives the moving piece 14 to move toward the center of the three-way pipe 13, thereby squeezing the air in the three-way pipe 13 to push the starting rod 17 downward, so that the starting rod 17 presses the switch on the air pump 16, starts the air pump 16, and draws external air into the cross pipe 3 through the intake pipe 18, and first passes through the cross pipe 3, the connecting piece 4 and the vertical pipe 2. The rack 21 is meshed with the gear 25, and the side plate 24 is driven to rotate upward. When the side plate 24 contacts the connecting piece 4, the side plate 24 cannot move further, and the rack 21 cannot move either. The pressure in the cross pipe 3 increases continuously. When the opening pressure of the pressure pipe 27 is reached, the air passes through the cross pipe 3 and the gear 25. The pressure tube 1 27 enters the airbag 26, so that the airbag 26 is inflated and expanded downward to contact the steel structure. When the airbag 26 cannot continue to expand, the pressure in the cross tube 3 continues to increase. When the opening pressure of the pressure tube 29 is reached, air enters the pressure tube 29, pushes out the push rod 30 and squeezes the return spring 31. When the push rod 30 is pushed out, it contacts the trigger rod 173, and then pushes the trigger rod 173 forward, so that the trigger rod 173 leaves the switch of the air pump 16, and the air pump 16 stops.

[0058] Then, use a lifting tool to lift the device through the movable groove opened at the bottom end of the base 1 and transfer it to a storage place. When the steel structure component is needed, transfer the base 1 to the required place, open the top plate 5 upward, take the positioning block 6 out of the connection box 8, and separate the pressure tube 27 from the connection hole 28. At this time, the locking head 12 loses its obstruction and is completely reset under the elastic action of the reset spring 11, causing the movable sheet 14 to move in the opposite direction, increasing the space inside the three-way pipe 13, thereby pulling up the start rod 17. Since the connection hole 28 loses the seal of the pressure tube 27, the gas in the cross tube 3 is directly discharged through the connection hole 28, and then the airbag 26 is deflated, and then the pressure relief valve 32 is opened. The air in the pressure tube 29 is discharged, so that the push rod 30 is reset under the elastic action of the reset spring 31, and the trigger rod 173 swings downward and resets under the action of gravity, and is adsorbed on the bottom of the lifting rod 171. In this process, the reset spring 23 in the compressed state pulls the rack 21 back under the action of elasticity, so that the side plate 24 rotates downward. The reverse movement of the rack 21 is slowed down by setting the damping rod 33 to achieve the effect of slowing down the falling speed of the side plate 24. When the side plate 24 is fully opened, you can choose to take out the steel structure components from the sides of the vertical tube 2 and the horizontal tube 3, or you can choose to directly tilt the device to make the steel structure components slide out completely to take out the steel structure components.

The method for using the construction engineering steel structure component transfer device according to claim 1, characterized in that: The steps include: Before the steel structure member is placed, the top plate (5) is in a dismantled state, and the side plate (24) is rotated to the lowest point; When placing the steel structure components, the operator can place the steel structure components directly onto the bottom bracket (1) through the vertical surface formed by the vertical pipe (2) and the horizontal pipe (3), and then continuously stack the steel structure components. When the top of the stacked steel structure components is almost flush with the horizontal pipe (3), stop placing the steel structure components. Subsequently, the top plate (5) is placed on the transverse tube (3) to ensure that the pressure tube (27) is inserted into the connecting hole (28). Then, the top plate (5) is pressed downward to achieve contact between the bottom surface of the top plate (5) and the top surface of the connecting piece (4). When the top plate (5) is pressed downward, the inclined surface at the bottom end of the positioning block (6) contacts the locking head (12), pushing the locking head (12) out of the connecting box (8). At this time, the return spring (11) is in a stretched state, and a pulling force is applied to the locking rod (9) through the connecting plate (10), so that the locking head (12) is always in contact with the positioning block (6). When the locking groove (7) and the locking head ( After the locking head (12) is aligned, the elastic force of the return spring (11) can clamp the locking head (12) in the locking groove (7), thereby fixing the position of the top plate (5). During the movement of the locking head (12), the locking rod (9) drives the moving plate (14) to move toward the center of the three-way pipe (13), thereby squeezing the air in the three-way pipe (13) to push the starting rod (17) downward, so that the starting rod (17) presses the switch on the air pump (16), starts the air pump (16), and draws external air into the cross pipe (3) through the air inlet pipe (18), and then passes through the cross pipe (3), the connecting piece (4) and The vertical pipe (2) first enters the connecting groove (19), and then enters the installation groove (20) through the connecting groove (19). As the air continues to enter, the pressure in the installation groove (20) continues to increase, and then the rack (21) can be pushed outward. Through the meshing of the rack (21) and the gear (25), the side plate (24) is driven to rotate upward. When the side plate (24) contacts the connecting piece (4), the side plate (24) cannot move further. At this time, the rack (21) cannot move either. The pressure in the horizontal pipe (3) continues to increase. When it reaches the opening pressure of the pressure pipe 1 (27), the air passes through the horizontal pipe. (3) and the pressure tube 1 (27) enter the airbag (26), so that the airbag (26) is inflated and expanded downward to contact the steel structure. When the airbag (26) can no longer expand, the pressure in the cross tube (3) continues to increase. When the opening pressure of the pressure tube 2 (29) is reached, air enters the pressure tube 2 (29), pushes the push rod (30) out and squeezes the return spring 3 (31). When the push rod (30) is pushed out, it contacts the trigger rod (173), thereby pushing the trigger rod (173) forward, so that the trigger rod (173) leaves the switch of the air pump (16), and the air pump (16) stops. Then, the device is lifted up through the movable groove opened at the bottom of the bottom bracket (1) by using a lifting tool and transported to a storage place. When the steel structure component is needed, the bottom bracket (1) is transported to the required place, the top plate (5) is opened upward, the positioning block (6) is taken out of the connection box (8), and the pressure tube (27) is separated from the connection hole (28). At this time, the locking head (12) loses its obstruction and is completely reset under the elastic action of the reset spring (11), so that the movable plate (14) moves in the opposite direction, increasing the space inside the three-way pipe (13), thereby pulling up the start rod (17), and because the connection hole (28) loses the seal of the pressure tube (27), the gas in the cross tube (3) is directly discharged through the connection hole (28), and then the air bag (26) is deflated, and then the pressure relief valve (32) is closed. ) is opened to discharge the air in the pressure tube 2 (29), so that the push rod (30) is reset under the elastic action of the reset spring 3 (31), and the trigger rod (173) is swung downward and reset under the action of gravity and is adsorbed on the bottom of the lifting rod (171). In this process, the reset spring 2 (23) in a compressed state pulls the rack (21) back under the action of elasticity, so that the side plate (24) rotates downward.
