Description

Technical Field

[0001] This invention belongs to the field of building construction technology, and specifically relates to a steel structure docking device. Background Technology

[0002] In building construction, reinforcing columns with steel plates is a common method to enhance structural strength. This typically involves placing angle steel at the four corners of the column and welding steel plates between adjacent angle steel to form a unified reinforced frame. Traditional steel plate reinforcement relies heavily on manual labor: workers manually move the steel plates, use a lifting platform to raise both themselves and the plates to a designated height, then one person assists in securing them while another performs the welding. This method requires workers to operate on the platform for extended periods, is unsafe, and is time-consuming and labor-intensive. Summary of the Invention

[0003] The purpose of this invention is to provide a steel structure docking device.

[0004] The present invention is achieved through the following measures: a steel structure docking device, characterized in that it includes a mobile vehicle, a guide column disposed on the mobile vehicle, a lifting mechanism disposed on the guide column, and a lifting plate disposed on the lifting mechanism;

[0005] The lifting plate is provided with a steel plate clamping structure, the rear end of the lifting plate is provided with a steel plate first pushing mechanism, and the front end of the lifting plate is provided with an opening that allows a steel plate to fall vertically.

[0006] Below the lifting plate and around the opening, there is a chamber for placing a vertically falling steel plate. Above the lifting plate, there is a steel plate ejection mechanism that ejects the steel plate at the opening into the chamber.

[0007] The front end of the chamber is open, allowing a steel plate to pass through. A second steel plate pushing mechanism is provided below the lifting plate. The second pushing mechanism pushes the steel plate out of the chamber and presses it against the angle steel.

[0008] Furthermore, welding mechanisms are provided on both sides of the front end of the lifting plate, and the welding guns of the welding mechanisms are used to weld the steel plate onto the angle steel.

[0009] Furthermore, the mobile vehicle includes a frame and a plurality of wheels mounted on the frame;

[0010] The guide posts are symmetrically arranged on both sides of the rear end of the vehicle frame, with two guide posts on each side. The upper ends of the two guide posts are fixed by reinforcing rods.

[0011] A rear upright plate is fixedly installed at the rear end of the lifting plate, and external ear plates are fixedly installed on the outer sides of both ends of the rear upright plate. Guide wheels that move up and down along the guide column are provided on both ear plates. An external horizontal plate is fixedly installed at the rear end of the rear upright plate. An annular groove is provided on the guide wheel, and the inner wall of the annular groove contacts the outer wall of the guide column. Several guide wheels can be provided according to the actual situation.

[0012] The lifting mechanism includes a lifting hydraulic cylinder and a lifting chain. The cylinder body of the lifting hydraulic cylinder is fixed on the vehicle frame. A sprocket is rotatably mounted on the upper end of the lifting push rod of the lifting hydraulic cylinder. The lower end of the lifting chain is mounted on the vehicle frame. The upper end of the lifting chain passes over the sprocket and is fixed to the external horizontal plate.

[0013] Furthermore, side plates are fixedly provided on both sides of the lifting plate, and the front ends of the two side plates are connected by a front upright plate; the opening is located between the lifting plate and the front upright plate;

[0014] The clamping structure includes two clamping plates symmetrically arranged inside the side plate. The lower end face of the clamping plate contacts the upper end face of the lifting plate. Several guide rods are fixedly arranged on the outer side of the clamping plates. Each guide rod is fitted with a spring, and the outer end of each guide rod extends out of the side plate. One end of the spring is fixed to the clamping plate, and the other end is fixed to the side plate. The outer end of the clamping plate extends downward into the cavity.

[0015] Furthermore, the cylinder of the first propulsion mechanism is fixed below the external horizontal plate, and the push rod of the first propulsion mechanism extends out of the rear vertical plate and the extended end is fixedly provided with a push plate, which is located between the two clamping plates.

[0016] Furthermore, the cylinder of the second propulsion mechanism is fixed below the lifting plate, and a mounting bracket is fixedly installed at the front end of the push rod of the second propulsion mechanism. An electromagnet is fixedly installed at the front end of the mounting bracket. Support rods are symmetrically arranged on the lifting plate on both sides of the second propulsion mechanism, and the mounting bracket is slidably mounted on the support rods.

[0017] Furthermore, an mounting plate is fixedly installed above the front end of the two side plates, the cylinder of the ejection mechanism is fixed on the mounting plate, a fixing plate is fixedly installed at the upper end of the push rod of the ejection mechanism, and push rods are fixedly installed at both ends of the outer side of the fixing plate. The mounting plate is provided with a strip-shaped opening that allows the two push rods to extend out. The thickness of the push rod is slightly smaller than the width of the opening, and the thickness of the push rod is about 0.5 mm smaller than the width of the opening.

[0018] Furthermore, it also includes a baffle plate disposed at the front end of the chamber, the upper sides of the baffle plate being rotatably disposed on the front upright plate, the baffle plate and the front upright plate being connected by a tension spring, the tension spring being unaffected by external force, the baffle plate being in a vertical state to prevent the steel plate entering the chamber from the opening from falling out, the baffle plate being located in the middle of the chamber and both ends of the chamber being exposed by the baffle plate.

[0019] Furthermore, the welding mechanism includes fixed seats on both sides of the front upright plate. A vertical lead screw is rotatably mounted on the fixed seat, and a sliding frame is threadedly connected to the lead screw. A slide rail that mates with the sliding frame is provided on the fixed seat, and the welding torch is mounted on the sliding frame. A motor for driving the lead screw to rotate is provided at either end of the lead screw, and the motor is fixed to the fixed seat.

[0020] Furthermore, the mobile vehicle can be electrically driven, which is existing technology and will not be described in detail here.

[0021] Furthermore, cylinder block one, cylinder block two, and cylinder block three can be pneumatic, electric, or hydraulic cylinders.

[0022] How to use:

[0023] Push the mobile vehicle to the vicinity of the column that needs to be reinforced, adjust the position of the vehicle frame so that the device faces the steel-clad part of the column (i.e. the location of the two angle steels and the steel plate can overlap the two angle steels after it is pushed out).

[0024] Multiple steel plates are placed vertically one by one between the clamping structures on the lifting plate (i.e., between two clamping plates). The clamping structures automatically clamp the two ends of all the steel plates under the action of springs.

[0025] Start the lifting mechanism. The lifting hydraulic cylinder pushes the sprocket, which in turn drives the lifting plate up and down through the lifting chain, so that the opening at the front of the lifting plate is aligned with the height at which the steel plate needs to be installed (determined according to the design height of the steel-clad column).

[0026] The first propulsion mechanism is activated, and the push rod of the first propulsion mechanism drives the push plate to move forward (in the direction of the angle steel) until the steel plate at the front end is pushed to the opening.

[0027] When the ejection mechanism is activated, the push rod of the ejection mechanism drives the fixed plate and the push rod to push the steel plate into the cavity until the lower end of the steel plate contacts the bottom wall of the cavity. When the push rod enters the opening, it can prevent the steel plate behind from moving forward.

[0028] The steel plate enters the chamber, and the second propulsion mechanism is activated. Push rod two drives the mounting frame and the electromagnet on the mounting frame to move. When the electromagnet moves into the chamber, the electromagnet is activated to attract the steel plate. The push rod three continues to move forward, the mounting frame slides along the support rod, and the baffle is opened under the thrust of the steel plate. At this time, the steel plate is pushed out from the front end of the chamber and hits the angle steel of the column.

[0029] Start the welding torch and lead screw, and use the lead screw to move the welding torch up and down to weld the steel plate and angle steel. (To ensure construction quality, the welded areas will need to be inspected and repaired later.)

[0030] After welding is completed, the electromagnet is turned off, the steel plate is stopped from being attracted, and the plate moves backward under the drive of the second propulsion mechanism. The baffle is reset under the action of the tension spring.

[0031] Repeat the operation: After the installation of one steel plate is completed, the lifting mechanism moves the lifting plate to the next height and repeats the above steps until all steel plates on one side of the column are installed.

[0032] The beneficial effects of the technical solution provided by the embodiments of the present invention are as follows: The steel structure docking device provided by the present invention integrates lifting, positioning, conveying, tightening and welding functions, which is conducive to the automation of steel reinforcement construction: the operator completes the batch loading of steel plates and the initial positioning of the device on the ground, and the subsequent lifting, plate delivery, tightening and welding can all be completed by the device, which is suitable for large-scale column reinforcement projects.

[0062] The mobile vehicle 1 can be electrically driven, which is existing technology and will not be described in detail here.

[0063] Cylinder block 1 (601), cylinder block 2 (801), and cylinder block 3 (701) can be pneumatic, electric, or hydraulic cylinders.

[0064] How to use:

[0065] Push the mobile vehicle 1 to the vicinity of the column that needs to be reinforced, and adjust the position of the frame 101 so that the device faces the steel-clad part of the column (i.e. the location of the two angle steels and the steel plate 11 can overlap the two angle steels after it is pushed out).

[0066] Multiple steel plates 11 are placed vertically one by one between the clamping structures 5 on the lifting plate 4 (i.e., between two clamping plates). Under the action of the spring 502, the clamping structures 5 automatically clamp the two ends of all the steel plates 11.

[0067] Start the lifting mechanism 3. The lifting hydraulic cylinder 301 pushes the sprocket 303, which drives the lifting plate 4 to move up and down through the lifting chain 304, so that the opening at the front end of the lifting plate 4 is aligned with the height at which the steel plate 11 needs to be installed (determined according to the design height of the steel-clad column).

[0068] The first propulsion mechanism 6 is activated. The push rod 602 of the first propulsion mechanism 6 drives the push plate 603 to move forward (in the direction of the angle steel) until the steel plate 11 at the front end is pushed to the opening.

[0069] When the ejection mechanism 7 is activated, the push rod 702 of the ejection mechanism 7 drives the fixed plate and the push rod 703 to push the steel plate 11 into the chamber 16 until the lower end of the steel plate 11 contacts the bottom wall of the chamber 16. When the push rod 703 enters the opening, it can prevent the steel plate 11 from moving forward.

[0070] When the steel plate 11 enters the chamber 16, the second propulsion mechanism 8 is activated. The second push rod 802 drives the mounting frame 803 and the electromagnet 804 on the mounting frame 803 to move. When the electromagnet 804 moves into the chamber 16, the electromagnet 804 is activated to attract the steel plate 11. The third push rod 702 continues to move forward. The mounting frame 803 slides along the support rod 13. The baffle 10 is opened under the thrust of the steel plate 11. At this time, the steel plate 11 is pushed out from the front end of the chamber 16 and hits the angle steel of the column.

[0071] Start the welding torch 904 and lead screw 902. The lead screw 902 drives the welding torch 904 to move up and down to weld the steel plate 11 and the angle steel. (To ensure construction quality, the welded joints will need to be inspected and repaired later.)

[0072] After welding is completed, the electromagnet 804 is turned off, the steel plate 11 is stopped from being attracted, and the plate moves backward under the drive of the second propulsion mechanism 8. The baffle 10 is reset under the action of the tension spring 12.

[0073] Repeat the operation: After the installation of one steel plate 11 is completed, the lifting mechanism 3 moves the lifting plate 4 to the next height and repeats the above steps until the installation of all steel plates 11 on one side of the column is completed.

[0074] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
