Description

Technical Field

[0001] The invention relates to the technical field of bridge steel material transportation mechanisms, and in particular to a large-span bridge steel material transportation mechanism and a use method thereof. Background Art

[0002] Steel is widely used and has a wide variety of applications. According to the different cross-sectional shapes, steel is generally divided into four categories: profiles, plates, pipes and metal products. During the production and processing of steel plates, the formed steel plates need to be transported. However, the existing steel plate transportation devices need to use ropes to fix the steel plates and transport them by carts. During the transportation process, the steel is prone to fall off, and in severe cases, it is easy to cause the steel to be damaged. In addition, general carts do not have lifting functions. When taking materials, people need to bend down to take materials, which is time-consuming.

[0003] A bridge generally refers to a structure built across rivers, lakes, and the sea to enable vehicles and pedestrians to pass smoothly. To adapt to the modern high-speed development of the transportation industry, bridges are also extended to refer to buildings that are built to cross mountain streams, poor geology, or meet other transportation needs to make travel more convenient. Bridges generally consist of an upper structure, a lower structure, supports, and ancillary structures. The superstructure, also known as the span structure, is the main structure for crossing obstacles; the lower structure includes abutments, piers, and foundations; supports are force transmission devices installed at the supporting locations between the span structure and the piers or abutments.

[0004] A large amount of steel bars are needed in the construction process of bridges. The current steel bar transportation devices generally use carts or manual labor for ground transportation, and use tower cranes or elevators to transport them to high-rise buildings. There is no transportation device that can be used for both ground transportation and tower crane transportation. When a tower crane is needed, the steel bars need to be taken off the cart and then tied up and lifted with ropes. This process is very troublesome. Therefore, the present application provides a large-span bridge steel transportation mechanism and a method of use to meet the needs. Summary of the invention

[0005] The technical problem to be solved by the present invention is to provide a large-span bridge steel transportation mechanism and a method of use to solve the problem that the existing steel bar transportation equipment generally uses a trolley or manual labor for ground transportation, and uses a tower crane or elevator for bundling transportation to high-rise buildings. There is no transportation device that can be used for both ground transportation and tower crane transportation.

[0009] Optionally, a rope is provided on the outer side of the rope shaft, one end of the rope is connected to the semicircular connecting hole, and the other end of the rope is connected to a small winch.

[0010] Optionally, the folding height component includes a second double-legged rotating cylinder and a third double-legged rotating cylinder, a second rotating rod is connected between the two second double-legged rotating cylinders and the third double-legged rotating cylinders, and a gravity sensor is respectively provided at one end of the two second double-legged rotating cylinders and the third double-legged rotating cylinders.

[0011] Optionally, a folding curtain is connected to the top of the second rotating rod, and a fixing block is respectively provided on the top surface of the folding curtain near the left and right ends.

[0012] Optionally, the transport bracket assembly includes a base plate, a top surface of the base plate is provided with a plurality of transmission wheels in an arranged form, a rotating motor is provided on the right side of the base plate near the center of the top surface, an output end of the rotating motor is connected to a gear, and the top surface of the base plate is covered with a placement plate.

[0013] Optionally, the top surface of the placement plate is covered with a chain at the right edge, and transmission grooves are respectively opened on the left and right sides of the center of the bottom surface of the placement plate. A rectangular frame is provided on the top of the four corners of the bottom plate, and splicing holes are respectively opened at the four corners of the top surface of the rectangular frame. Lifting rods are respectively connected to the centers of the four surfaces of the rectangular frame.

[0014] Optionally, the high-position steel barrel assembly includes two support rods, a first steel barrel is provided on the top of the two support rods, first fasteners are provided on the left and right sides of the inner surface of the first steel barrel near the front and rear ends, and a first belt is connected between the two first fasteners on each side.

[0015] Optionally, the low-level steel storage barrel assembly includes a second steel barrel, and second fasteners are respectively provided on the left and right sides of the inner surface of the second steel barrel near the front and rear ends, a second belt is connected between the two second fasteners on each side, and clamping screws are respectively provided on the outer surfaces of the front and rear ends of the second steel barrel.

[0016] A method for using a long-span bridge steel material transportation mechanism comprises the following steps:

[0017] Step 1: Installation step: install the high-position steel storage barrel assembly and the low-position steel storage barrel assembly side by side on the surface of the transport bracket assembly to store steel. In addition, the two fixed blocks in the folding height assembly structure on the surface of the weighing cart assembly at the bottom are welded and fixed to the bottom of the transport bracket assembly. The small magnetic steel lifting assembly placed on the surface of the triangular plate bracket can use the use of a crane to use magnetic suction to transport steel when loading and transporting steel;

[0018] Step 2: The weighing cart assembly uses the foot brake pulley, triangular plate bracket and handle to facilitate the staff to push the cart to the designated position, and then step on the foot brake of the foot brake pulley to fix the cart. The electronic floor scale plate is connected to the gravity sensor and the weight alarm, which can record the gravity of the installed steel in real time. When the load-bearing capacity of the weighing cart assembly is exceeded, the weight alarm will sound to alert the staff, thereby improving safety and preventing overweight construction accidents.

[0019] Step 3, the folding height component is a common folding lifting platform. In addition, when transporting steel, a small magnetic steel lifting component can be used to adjust the direction to the steel, and use a small winch to pull in and release the line to adjust the up and down angles of the first rotating rod to a suitable position to use the magnetic rod at one end to absorb the steel. The adsorption function of the magnetic rod is controlled by the magnetic controller, and the whole crane working mode is formed to transport the steel to the inside of the transport bracket assembly;

[0020] Step 4: The rotating motor, gear, placement plate, chain, transmission trough and transmission wheel in the transport bracket assembly structure can use the rotating motor to drive the gear to rotate to move the placement plate left and right to move out of the front and back outside of the transport bracket, so as to facilitate the extraction of steel on site. In addition, the lifting rod can also cooperate with the crane to transport the entire device;

[0021] Step 5. The steel cylinders in the high-position storage steel cylinder assembly and low-position storage steel cylinder assembly structure are used to place steel. The overall placement position is one at a low position and the other at a high position, which will not affect the friction between the steels in the same row. In addition, when placing multiple steels in one cylinder with fasteners and belts, you can first lift the belts and fasteners to form a circular binding with the steel cylinder, and then insert the steel from both sides. If there are only a few steels, you can place them directly in the steel cylinder without bundling with belts.

[0022] Compared with the prior art, the present invention has at least the following beneficial effects:

[0023] In the above scheme, by setting up a weighing cart assembly, using a foot brake pulley, a triangular plate bracket and a handle, it is convenient for the staff to push the cart to the designated position, and then step on the foot brake of the foot brake pulley to fix the cart, wherein the electronic floor scale plate is connected to the gravity sensor and the weight alarm, and the gravity of the installed steel can be recorded in real time. When the load-bearing capacity of the weighing cart assembly is exceeded, the weight alarm will sound to alert the staff, thereby improving safety and preventing overweight construction accidents. In addition, the steel cylinders in the high-position steel cylinder assembly and the low-position steel cylinder assembly structure are used to place steel. The overall placement position is one at a low position and the other at a high position, which will not affect the friction between the steels in the same row. In addition, when placing multiple steels in a cylinder with fasteners and belts, the belts and fasteners can be lifted first to form a circular binding with the steel cylinder, and then the steel can be inserted from both sides. If there are only a few steels, they can be placed directly in the steel cylinder without belt binding.

[0024] By setting up a rotating motor, gears, placement plates, chains, transmission troughs and transmission wheels in the transport bracket assembly structure, the rotating motor can be used to drive the gears to rotate and move the placement plates left and right to move out of the front and rear outer sides of the transport bracket, so as to facilitate the on-site extraction of steel. In addition, the lifting rod can also be used in conjunction with a crane to transport the entire device. In addition, the splicing holes opened at the four corners of the top of the rectangular frame are used. If the load-bearing capacity of the weighing pallet assembly at the bottom is high, and a rectangular frame has been filled with steel but has not reached the load-bearing index, you can choose to use the splicing holes to splice another rectangular frame to continue loading steel.

The overall placement position is one at a low position and the other at a high position, which will not affect the friction between the steels in the same row. In addition, when placing multiple steels in a cylinder with fasteners and belts, the belts and fasteners can be lifted up to form a circle with the steel cylinder. Bundling type, and then insert the steel from both sides. If there are only a few steels, they can be placed directly in the steel tube without belt bundling. Then, by setting the rotating motor 403, gear 404, placement plate 405, chain 406, transmission groove 407 and transmission wheel 402 in the structure of the transport bracket assembly 4, the rotating motor 403 can be used to drive the gear 404 to rotate and move the placement plate 405 left and right to move out of the front and back outside of the transport bracket, so as to facilitate the on-site extraction of steel.

The small magnetic steel lifting assembly placed on the surface of the triangular plate bracket can use the use of a crane to use magnetic suction to transport steel when loading and transporting steel; Step 2: The weighing cart assembly uses the foot brake pulley, triangular plate bracket and handle to facilitate the staff to push the cart to the designated position, and then step on the foot brake of the foot brake pulley to fix the cart. The electronic floor scale plate is connected to the gravity sensor and the weight alarm, which can record the gravity of the installed steel in real time. When the load-bearing capacity of the weighing cart assembly is exceeded, the weight alarm will sound to alert the staff, thereby improving safety and preventing overweight construction accidents. Step 3, the folding height component is a common folding lifting platform. In addition, when transporting steel, a small magnetic steel lifting component can be used to adjust the direction to the steel, and use a small winch to pull in and release the line to adjust the up and down angles of the first rotating rod to a suitable position to use the magnetic rod at one end to absorb the steel. The adsorption function of the magnetic rod is controlled by the magnetic controller, and the whole crane working mode is formed to transport the steel to the inside of the transport bracket assembly; Step 4: The rotating motor, gear, placement plate, chain, transmission trough and transmission wheel in the transport bracket assembly structure can use the rotating motor to drive the gear to rotate to move the placement plate left and right to move out of the front and back outside of the transport bracket, so as to facilitate the extraction of steel on site. In addition, the lifting rod can also cooperate with the crane to transport the entire device; Step 5. The steel cylinders in the high-position storage steel cylinder assembly and low-position storage steel cylinder assembly structure are used to place steel. The overall placement position is one at a low position and the other at a high position, which will not affect the friction between the steels in the same row. In addition, when placing multiple steels in one cylinder with fasteners and belts, you can first lift the belts and fasteners to form a circular binding with the steel cylinder, and then insert the steel from both sides. If there are only a few steels, you can place them directly in the steel cylinder without bundling with belts.
