Description

Technical Field

[0001] This invention relates to the field of construction technology, and in particular to a construction material handling device and a material handling method thereof. Background Technology

[0002] During construction, a large amount of materials need to be delivered to the construction site. Due to the obstructed roads at the construction site, vehicles can only deliver materials to the entrance of the construction site. The remaining materials need to be manually carried to the construction site. Therefore, workers usually use transport vehicles to assist in the transportation of materials.

[0003] The existing handling equipment has the following shortcomings: 1. The handling equipment is generally a small trolley, while building materials are generally heavy and difficult to move when the trolley is full; 2. When loading and unloading materials, workers need to manually handle them, which is inconvenient to use. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies where transport trolleys are difficult to move, and to propose a construction material transport device.

[0005] To address the problem of existing technologies where transport trolleys are difficult to move, the present invention adopts the following technical solution:

[0006] A construction material handling device includes a vehicle body with wheels at the bottom and a handrail at the front. A mounting frame, which is a hollow, rounded rectangle, is located at the bottom of the vehicle body. Sleeves are fixedly connected to both ends of the mounting frame, and mounting rods are fitted inside each sleeve and fixedly connected to the bottom of the vehicle body. A base plate is hinged to the bottom of the mounting frame. Racks are fixedly connected to the upper and lower ends of the inner side of the mounting frame. A mounting shaft is rotatably connected to the bottom of the vehicle body, passing through the mounting frame. A motor is located at one end of the mounting shaft, and a half-gear is fixedly connected to the middle of the mounting shaft, meshing with the rack. A limiting plate is fixedly connected to the bottom of the mounting frame, and the limiting plate is in contact with the top of the base plate.

[0007] Preferably, a fixed frame is fixedly connected to the top of the vehicle body, a translation component is fixedly connected to the top of the fixed frame, a compensation component is provided at the bottom of the translation component, a mounting plate is fixedly connected to the bottom of the compensation component, a take-up roller is rotatably connected to the bottom of the mounting plate, and a motor is provided at one end of the take-up roller. A connecting rope is wound around the outer surface of the take-up roller, and a hook is fixedly connected to the bottom of the connecting rope.

[0008] Preferably, the translation component includes a first slide rail, which is fixedly connected to the top of the fixed frame. A first threaded rod is rotatably connected inside the first slide rail, and a motor is provided at one end of the first threaded rod. A first slider is threadedly connected to the outer surface of the first threaded rod, and the first slider is slidably connected inside the first slide rail. The bottom end of the first slider is fixedly connected to the compensation component.

[0009] Preferably, the compensation component includes a second slide rail, which is fixedly connected to the bottom end of the first slider. A second threaded rod is rotatably connected inside the second slide rail, and a motor is provided at one end of the second threaded rod. A second slider is threadedly connected to the outer surface of the second threaded rod, and the second slider is slidably connected inside the second slide rail. The bottom end of the second slider is fixedly connected to the mounting plate.

[0010] Preferably, the left and right sides of the insert plate are provided with sliding grooves, and each of the two sliding grooves is provided with a movable block, and the two movable blocks are slidably connected to the bottom of the mounting frame.

[0011] Preferably, a magnet is fixedly connected inside the insert plate, and the magnet cooperates with the mounting bracket.

[0012] Preferably, the front end of the vehicle body has a groove, and the handrail is hinged inside the groove. The front end of the vehicle body is rotatably connected to a limit rod, and the limit rod is located on the top front side of the groove.

[0013] Preferably, the front end of the vehicle body is fixedly connected to two limiting brackets, which are respectively arranged on the left and right sides of the bottom of the groove.

[0014] Preferably, a spring is fixedly connected to the bottom of the vehicle body, and a base plate is fixedly connected to the top of the spring, with the base plate slidably connected inside the vehicle body.

[0015] This invention also proposes a method for handling construction materials using a material handling device, comprising the following steps:

[0016] Step 1: Rotate the limiting rod to displace it from the groove, and remove the handrail from inside the groove. With the support of the limiting frame, the handrail will not fall to the ground. Hold the handrail and pull the vehicle body. The wheels will roll, pulling the vehicle body to the loading area.

[0017] Step 2: When the vehicle body moves to the cargo location, the motor drives the first threaded rod to rotate. The rotation of the first threaded rod causes the first slider to move backward along the first slide rail until the first slider moves to the rear end of the vehicle body. Then, the motor drives the second threaded rod to rotate. The rotation of the second threaded rod causes the second slider to move backward along the second slide rail, moving the mounting plate to the outside of the vehicle body.

[0018] Step 3: After the mounting plate is moved to the outside of the vehicle body, the motor drives the take-up roller to rotate. The rotating take-up roller releases the connecting rope, causing the hook to descend. After the hook catches the material, the motor drives the take-up roller to reverse, and the connecting rope is rewound around the take-up roller, lifting the material up. Then, the compensation component and the translation component work to bring the material to the top of the vehicle body, and then the material is lowered to the bottom plate inside the vehicle body. This cycle continues until the vehicle body is full.

[0019] Step 4: After the vehicle is fully loaded, hold the handle and pull the vehicle to transport the materials to the construction site. During the pulling process, the motor drives the mounting shaft to rotate, and the rotating mounting shaft drives the half gear to rotate. The rotating half gear meshes with the rack inside the mounting frame. When the half gear meshes with the rack at the bottom of the mounting frame, the mounting frame moves backward, which in turn causes the limiting plate to apply force to the insertion plate, causing the insertion plate to insert into the ground. The reaction force of the ground on the insertion plate causes the vehicle to move forward through the mounting shaft, assisting the workers and making it easier to pull the vehicle. When the half gear meshes with the rack at the top of the mounting frame, the mounting frame moves forward, which in turn pulls the insertion plate out of the ground.

[0020] Step 5: During the vehicle's movement, vibrations are generated, causing the material to press down on the bottom plate and springs. The springs are compressed, and the material moves downwards. The energy is dissipated during the cyclical compression and expansion of the springs, which has a shock-absorbing effect and prevents some rigid materials from being damaged.

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] 1. In this invention, the motor drives the mounting shaft to rotate, and the rotating mounting shaft drives the half gear to rotate. The rotating half gear meshes with the rack inside the mounting frame. When the half gear meshes with the rack at the bottom of the mounting frame, the mounting frame moves backward, thereby causing the limiting plate to apply force to the insertion plate, causing the insertion plate to insert into the ground. The reaction force of the ground on the insertion plate moves the vehicle forward through the mounting shaft, assisting the worker and making the vehicle easier to pull.

[0023] 2. In this invention, the translation component and the compensation component drive the mounting plate to move, the motor drives the take-up roller to rotate, and the take-up and unwinding actions are completed. The hook moves up and down to lift and lower the material, which facilitates the loading and unloading of the transport trolley and makes it easy to use.

[0024] In summary, the present invention uses an electric motor to drive the mounting shaft to rotate, which in turn drives a half-gear to rotate. The rotating half-gear meshes with a rack inside the mounting frame. When the half-gear meshes with the rack at the bottom of the mounting frame, the mounting frame moves backward, thereby causing the limiting plate to apply force to the insertion plate, causing the insertion plate to insert into the ground. The reaction force of the ground on the insertion plate moves the vehicle forward through the mounting shaft, assisting the worker and making the vehicle easier to pull. The translation component and compensation component drive the mounting plate to move, and the electric motor drives the take-up roller to rotate, completing the take-up and undoing of the wire. The hook moves up and down to lift and lower the material, facilitating the loading and unloading of the transport trolley and making it convenient to use. Attached Figure Description

[0034] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0035] Example 1: This example provides a construction material handling device, see below. Figure 1-7 Specifically, the vehicle body 1 has wheels 2 at its bottom and a handrail 7 at its front. A mounting frame 10, which is a hollow, rounded rectangle, is located at the bottom of the vehicle body 1. Sleeves 11 are fixedly connected to both ends of the mounting frame 10, and mounting rods 12 are fitted inside each sleeve 11. The mounting rods 12 are fixedly connected to the bottom of the vehicle body 1. A base plate 24 is hinged to the bottom of the mounting frame 10. A rack 26 is fixedly connected to the upper and lower ends of the inner side of the mounting frame 10. A mounting shaft 28 is rotatably connected to the bottom of the vehicle body 1, passing through the mounting frame 10. A motor is installed at one end of the mounting shaft 28. A half-gear 27 is fixedly connected to the middle of the mounting shaft 28, meshing with the rack 26. A limiting plate 25 is fixedly connected to the bottom of the mounting frame 10, and the limiting plate 25 is in contact with the top of the base plate 24.

[0036] The motor drives the mounting shaft 28 to rotate, and the rotating mounting shaft 28 drives the half gear 27 to rotate. The rotating half gear 27 meshes with the rack 26 inside the mounting frame 10. When the half gear 27 meshes with the rack 26 at the bottom of the mounting frame 10, the mounting frame 10 moves backward, thereby causing the limiting plate 25 to apply force to the insertion plate 24, causing the insertion plate 24 to insert into the ground. The reaction force of the ground on the insertion plate 24 moves the vehicle body 1 forward through the mounting shaft 28, assisting the workers and making it easier to pull the vehicle body 1. When the half gear 27 meshes with the rack 26 at the top of the mounting frame 10, the mounting frame 10 moves forward, thereby pulling the insertion plate 24 out of the ground.

[0037] When the vehicle body 1 is climbing a slope, if the vehicle body 1 begins to slide down, the insert plate 24 will insert into the ground, and the limiting plate 25 will abut against the front of the insert plate 24, which can fix the vehicle body 1 on the slope and prevent the vehicle body 1 from sliding down and accidentally injuring others.

[0038] In the specific implementation process, such as Figure 2 and Figure 6As shown, the floor plate 24 has grooves 30 on both the left and right sides. Each groove 30 has a movable block 29 inside. Both movable blocks 29 are slidably connected to the bottom of the mounting frame 10. A magnet 23 is fixedly connected inside the floor plate 24 and cooperates with the mounting frame 10. When the vehicle body 1 needs to move backward, the movable block 29 is moved to move backward along the groove 30, causing the floor plate 24 to rotate until one end of the floor plate 24 is raised and separated from the ground. The magnet 23 is attracted to the mounting frame 10, fixing the floor plate 24 to the bottom of the mounting frame 10.

[0039] In the specific implementation process, such as Figure 1 and Figure 2 As shown, a groove 8 is provided at the front end of the vehicle body 1, and the handrail 7 is hinged inside the groove 8. The handrail 7 is retractable to improve its applicability. A limit rod 9 is rotatably connected to the front end of the vehicle body 1, and the limit rod 9 is located on the top front side of the groove 8. Two limit frames 6 are fixedly connected to the front end of the vehicle body 1. The two limit frames 6 are respectively located on the left and right sides of the bottom of the groove 8. Rotating the limit rod 9 causes the limit rod 9 to be misaligned with the groove 8, and the handrail 7 can be taken out from inside the groove 8. With the support of the limit frames 6, the handrail 7 will not fall to the ground. Holding the handrail 7, pull the vehicle body 1, and the driving wheels 2 will roll, pulling the vehicle body 1 to the loading area.

[0040] In the specific implementation process, such as Figure 1 and Figure 3 As shown, a spring 13 is fixedly connected to the bottom of the interior of the vehicle body 1, and a base plate 5 is fixedly connected to the top of the spring 13. The base plate 5 is slidably connected inside the vehicle body 1. When the vehicle body 1 moves, it vibrates, and the material presses down on the base plate 5 and the spring 13. The spring 13 is squeezed, and the material moves downward. In the process of the spring 13 being compressed and opened in cycles, energy is consumed, which plays a shock absorption role and avoids damage to some rigid materials.

[0041] Example 2: In Example 1, there was still a problem with the difficulty of loading and unloading materials. Therefore, based on Example 1, this example also includes:

[0042] In the specific implementation process, such as Figure 1 , Figure 3 and Figure 4As shown, a fixed frame 3 is fixedly connected to the top of the vehicle body 1. A translation component is fixedly connected to the top of the fixed frame 3. A compensation component is provided at the bottom of the translation component. A mounting plate 14 is fixedly connected to the bottom of the compensation component. A take-up roller 21 is rotatably connected to the bottom of the mounting plate 14. A motor is provided at one end of the take-up roller 21. An electromagnetic brake is provided inside the motor at the take-up roller 21 to fix the state of the take-up roller 21. A connecting rope 22 is wound around the outer surface of the take-up roller 21. A hook 20 is fixedly connected to the bottom of the connecting rope 22. The mounting plate 14 is moved by the translation component and the compensation component. The motor drives the take-up roller 21 to rotate, completing the take-up and unwinding action. The hook 20 moves up and down to lift and lower the material, which facilitates the loading and unloading of the transport trolley and is convenient to use.

[0043] In the specific implementation process, such as Figure 3 and Figure 4 As shown, the translation component includes a first slide rail 4, which is fixedly connected to the top of the fixed frame 3. A first threaded rod 15 is rotatably connected inside the first slide rail 4, and a motor is provided at one end of the first threaded rod 15. A first slider 16 is threadedly connected to the outer surface of the first threaded rod 15, and the first slider 16 is slidably connected inside the first slide rail 4. The bottom end of the first slider 16 is fixedly connected to the compensation component. The motor drives the first threaded rod 15 to rotate, and the rotation of the first threaded rod 15 causes the first slider 16 to move backward along the first slide rail 4, thereby driving the compensation component and the hook 20 to move backward.

[0044] In the specific implementation process, such as Figure 3 and Figure 4 As shown, the compensation component includes a second slide rail 17, which is fixedly connected to the bottom end of the first slider 16. The length of the second slide rail 17 behind the first slider 16 is greater than the length in front of the first slider 16, allowing the hook 20 to move to the outside of the vehicle body 1. A second threaded rod 18 is rotatably connected inside the second slide rail 17, and a motor is provided at one end of the second threaded rod 18. A second slider 19 is threadedly connected to the outer surface of the second threaded rod 18, and the second slider 19 is slidably connected inside the second slide rail 17. The bottom end of the second slider 19 is fixedly connected to the mounting plate 14. The motor drives the second threaded rod 18 to rotate, and the rotation of the second threaded rod 18 causes the second slider 19 to move backward along the second slide rail 17, moving the mounting plate 14 to the outside of the vehicle body 1.

[0045] Example 3: See Figure 7 Specifically, the working principle and operation method of this invention are as follows:

[0046] Step 1: Rotate the limiting rod 9 to make the limiting rod 9 misalign with the groove 8, and take out the handrail 7 from the inside of the groove 8. With the support of the limiting frame 6, the handrail 7 will not fall to the ground. Hold the handrail 7 and pull the vehicle body 1. The driving wheels 2 will roll and pull the vehicle body 1 to the loading area.

[0047] Step 2: The vehicle body 1 moves to the cargo location, and the motor drives the first threaded rod 15 to rotate. The rotation of the first threaded rod 15 causes the first slider 16 to move backward along the first slide rail 4 until the first slider 16 moves to the rear end of the vehicle body 1. Then the motor drives the second threaded rod 18 to rotate, and the rotation of the second threaded rod 18 causes the second slider 19 to move backward along the second slide rail 17, so that the mounting plate 14 moves to the outside of the vehicle body 1.

[0048] Step 3: After the mounting plate 14 moves to the outside of the vehicle body 1, the motor drives the take-up roller 21 to rotate. The rotating take-up roller 21 releases the connecting rope 22, causing the hook 20 to descend. After the hook 20 hooks the material, the motor drives the take-up roller 21 to reverse, and the connecting rope 22 is rewound onto the take-up roller 21, lifting the material. Then, the compensation component and the translation component work to bring the material to the top of the vehicle body 1, and then the material is lowered onto the bottom plate 5 inside the vehicle body 1. This cycle continues until the vehicle body 1 is full.

[0049] Step 4: After the vehicle body 1 is full, hold the handle 7 and pull the vehicle body 1 to transport the materials to the construction site. During the pulling process, the motor drives the mounting shaft 28 to rotate. The rotating mounting shaft 28 drives the half gear 27 to rotate. The rotating half gear 27 meshes with the rack 26 inside the mounting frame 10. When the half gear 27 meshes with the rack 26 at the bottom of the mounting frame 10, the mounting frame 10 moves backward, which in turn causes the limiting plate 25 to apply force to the insertion plate 24, causing the insertion plate 24 to insert into the ground. The reaction force of the ground on the insertion plate 24 moves the vehicle body 1 forward through the mounting shaft 28, assisting the workers and making it easier to pull the vehicle body 1. When the half gear 27 meshes with the rack 26 at the top of the mounting frame 10, the mounting frame 10 moves forward, which in turn pulls the insertion plate 24 out of the ground.

[0050] Step 5: During the movement of the vehicle body 1, vibrations are generated, and the material presses down on the bottom plate 5 and spring 13. Spring 13 is compressed, and the material moves downward. In the process of the spring 13 being compressed and opened in cycles, energy is consumed, which plays a shock absorption role and avoids damage to some rigid materials.

[0051] In this invention, the motor drives the mounting shaft 28 to rotate, and the rotating mounting shaft 28 drives the half gear 27 to rotate. The rotating half gear 27 meshes with the rack 26 inside the mounting frame 10. When the half gear 27 meshes with the rack 26 at the bottom of the mounting frame 10, the mounting frame 10 moves backward, thereby causing the limiting plate 25 to apply force to the insertion plate 24, causing the insertion plate 24 to insert into the ground. The reaction force of the ground on the insertion plate 24 moves the vehicle body 1 forward through the mounting shaft 28, assisting the workers. The translation component and the compensation component drive the mounting plate 14 to move, and the motor drives the take-up roller 21 to rotate, completing the take-up and undoing of the wire. The hook 20 moves up and down to lift and lower the material, facilitating the loading and unloading of the transport trolley and making it convenient to use.

[0052] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
