Abstract
Description
Technical Field
[0001] This utility model relates to the field of material transfer technology, and in particular to a material transfer device for construction sites. Background Technology
[0002] As cities develop, surface traffic becomes increasingly congested, far from meeting the travel needs of high-density populations. Therefore, some densely populated cities have built complex and cumbersome subway lines underground to alleviate some of the surface traffic congestion. During subway construction, due to the massive amount of work, manual short-distance material handling is no longer sufficient to meet the needs of subway construction. Therefore, there is an urgent need for a short-distance material transfer device to help construction workers speed up the subway construction process.
[0003] During subway construction, construction materials need to be transported to the construction site. Currently, the transport equipment used is mostly trolleys. During the loading process, the materials need to be moved from the ground to the interior of the carriage, which is quite laborious. The same disadvantage exists when unloading materials, especially when the materials are heavy, which makes it even more difficult to move them. This reduces transportation efficiency and slows down the subway construction speed. Utility Model Content
[0004] In order to overcome the shortcomings of the prior art, the purpose of this utility model is to provide a construction material transfer device. This transfer device can add materials by reciprocating rotation of the cylinder and control the discharge of materials by rotating the cylinder. It is easy to control and simple to use. In addition, the structure of this utility model is relatively simple and easy to manufacture.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A material transfer device for construction sites includes two mounting plates, one in front and one behind. Each mounting plate has a movable wheel on its lower side. A lifting device is installed between the movable wheel and the corresponding mounting plate. A connecting shaft is fixedly installed between the opposite surfaces of the mounting plates. A cylinder is installed between the mounting plates. The connecting shaft passes through the cylinder and is rotatably connected. A drive device is installed on the mounting plate to rotate the cylinder. An opening is provided on the outer periphery of the cylinder. A vertical plate is installed inside the cylinder. The connecting shaft is rotatably connected to the upper part of the vertical plate via a connecting ring. A torsion spring and a limiting structure are provided between the vertical plate and the connecting shaft. A baffle is fixedly installed at the bottom of the cylinder, preventing the vertical plate from passing underneath.
[0007] In a preferred embodiment of this utility model, the lifting device consists of several electric push rods, which are respectively fixedly installed on both sides of the back of the mounting plate, and the movable ends of the electric push rods are respectively fixedly connected to corresponding moving wheels.
[0008] As a preferred embodiment of this utility model, the driving device includes a motor, a gear, and a gear ring. The motor is fixedly installed on the front of the front mounting plate, the output shaft of the motor passes through the mounting plate and is rotatably connected, the gear is fixedly installed on the output shaft of the motor, and the gear ring is fixedly installed on the front side of the cylinder, with the gear meshing with the gear ring.
[0009] In a preferred embodiment of this invention, the motor is a servo motor.
[0010] As a preferred embodiment of this utility model, a single movable handle is fixedly installed on one side of the mounting plate.
[0011] As a preferred embodiment of this utility model, the limiting structure consists of a groove and a slider. The groove is formed on the outer periphery of the connecting shaft and is a semi-circular groove. The slider is fixedly installed on the inner wall of the connecting ring and is located in the groove and can slide along it.
[0012] As a preferred embodiment of this utility model, a protective pad is fixedly installed on the outer periphery of the cylinder.
[0013] Beneficial effects:
[0014] 1. By driving the cylinder to rotate clockwise, the opening faces downward to the right. A lifting device moves the mounting plate downward, bringing the cylinder into contact with the ground. Moving the cylinder to the right allows material on the ground to enter through the opening. The material accumulates between the opening and the baffle. The lifting device then moves the mounting plate upward a short distance, creating a gap between the cylinder and the ground. Finally, the driving device drives the cylinder to rotate counter-clockwise, allowing material to enter the bottom of the cylinder through the baffle. The driving device then drives the cylinder to rotate clockwise... Rotating the cylinder clockwise causes the opening to face downwards to the right. The baffle pushes the material into the left side of the vertical plate. The baffle and vertical plate prevent the material from escaping. Repeating this operation allows the material to continuously enter the cylinder. When the material needs to be discharged, the drive device rotates the cylinder counterclockwise, causing the opening to face downwards, allowing the material to be discharged along the opening. Compared with the prior art, this invention can add material through the reciprocating rotation of the cylinder and control the discharge of material through the rotation of the cylinder. It is convenient to control and simple to use. In addition, the structure of this invention is relatively simple and easy to manufacture.
[0015] 2. By controlling the synchronous extension and retraction of the electric actuator, the two mounting plates can be moved up and down synchronously. The lifting device has a simple structure and is easy to use.
[0016] 3. The rotation of the motor's output shaft can drive the gear to rotate, and the rotation of the gear can drive the cylinder to rotate through the gear ring. This drive device has a simple structure and is easy to use and control.
[0017] 4. Servo motors offer more precise position control and are easier to use.
[0018] 5. The movable handle provides a point of leverage for the user, making it more convenient to use.
[0019] 6. The slide and slider can limit the rotation angle of the vertical plate. The limiting structure is simple and easy to manufacture.
[0020] 7. The protective pad can reduce wear caused by the contact between the outer periphery of the cylinder and the ground. Attached Figure Description

[0024] Example
[0025] Reference Figure 1A material transfer device for construction sites includes two mounting plates 1, one in front of the other. Movable wheels 2 are respectively installed on the lower sides of the mounting plates 1. A lifting device is installed between the movable wheels 2 and the corresponding mounting plates 1. A connecting shaft 3 is fixedly installed between the opposite faces of the mounting plates 1. A cylinder 4 is installed between the mounting plates 1. The connecting shaft 3 passes through the cylinder 4 and is rotatably connected. A drive device is installed on the mounting plates 1 to drive the cylinder 4 to rotate. An opening 5 is opened on the outer periphery of the cylinder 4, located at the lower right part of the cylinder 4. A vertical plate 5 is installed inside the cylinder 4. The connecting shaft 3 is rotatably connected to the upper part of the vertical plate 5 via a connecting ring 6. A torsion spring and a limiting structure are installed between the vertical plate 5 and the connecting shaft 3. A baffle 7 is fixedly installed at the bottom of the cylinder 4, preventing the lower part of the vertical plate 5 from passing through. The drive device drives the cylinder 4 to rotate clockwise, causing the opening to face downwards to the right. The lifting device moves the mounting plates 1 downwards, allowing the cylinder 4 to contact the ground. Moving the device allows the cylinder 4 to move to the right. Moving the cylinder 4 to the right allows materials on the ground to enter the cylinder 4 through the opening. The materials accumulate between the opening and the baffle 7. The lifting device drives the mounting plate 1 to move upward a short distance, creating a gap between the cylinder 4 and the ground. The driving device drives the cylinder 4 to rotate counterclockwise, allowing materials to enter the bottom of the cylinder 4 through the baffle 5. The driving device drives the cylinder 4 to rotate clockwise, causing the opening to face downward to the right. The baffle 7 pushes the materials to the left side of the vertical plate 5. The baffle 7 and the vertical plate 5 prevent materials from escaping. Repeating the above operation allows materials to continuously enter the cylinder 4. When it is necessary to discharge materials, the driving device drives the cylinder 4 to rotate counterclockwise, causing the opening to face downward, allowing the materials to be discharged through the opening. Compared with the prior art, this utility model can add materials through the reciprocating rotation of the cylinder 4 and control the discharge of materials through the rotation of the cylinder 4. It is convenient to control and simple to use. In addition, the structure of this utility model is relatively simple and easy to manufacture.
[0026] like Figure 1As shown, the lifting device consists of several electric actuators 8, which are fixedly installed on both sides of the back of the mounting plate 1. The movable ends of the electric actuators 8 are fixedly connected to corresponding moving wheels 2. By controlling the synchronous extension and retraction of the electric actuators 8, the two mounting plates 1 can be driven to move up and down synchronously. The lifting device has a simple structure. The driving device includes a motor 9, a gear 10, and a gear ring 11. The motor 9 is fixedly installed on the front of the front mounting plate 1, and the output shaft of the motor 9 passes through the mounting plate 1 and is rotatably connected. The gear 10 is fixedly installed on the output shaft of the motor 9, and the gear ring 11 is fixedly installed on the front side of the cylinder 4. The gear 10 and the gear ring 11 mesh. When the motor 9 is turned on, the output shaft of the motor 9 rotates, which drives the gear 10 to rotate. The rotation of the gear 10 drives the cylinder 4 to rotate through the gear ring 11. The drive device has a simple structure and is easy to use and control. The motor 9 is a servo motor. Compared with other types of motors 9, the servo motor has more precise position control and is easier to use. The same moving handle 12 is fixedly installed on one side of the mounting plate 1. The moving handle 12 can provide a point of force for the user and make it more convenient to use. The limiting structure is a groove and a slider. The groove is opened on the outer periphery of the connecting shaft 3. The groove is a semi-arc groove. The slider is fixedly installed on the inner wall of the connecting ring 6. The slider is located in the groove and can slide along it. The groove and the slider can limit the rotation angle of the vertical plate 5. The limiting structure is simple and easy to manufacture. A protective pad is fixedly installed on the outer periphery of the cylinder 4. The protective pad can reduce the wear caused by the outer periphery of the cylinder 4 contacting the ground.
