[0001] This utility model relates to the field of building construction technology, and in particular to a material transfer trolley for building construction. Background Technology

[0002] Construction material transport carts are devices specifically designed to help construction workers move materials such as timber, bricks, and metal sheets between different locations on a construction site. Their use reduces the difficulty for construction workers in moving materials and improves construction efficiency.

[0003] CN220410596U discloses a material transfer vehicle for construction sites, including a first limiting support plate, a storage box on the upper surface of the first limiting support plate, a support mechanism below the first limiting support plate, a plurality of partition plates spaced apart on one side of the storage box, a support base fixedly connected to the upper surface of the first limiting support plate and slidably connected to the partition plates, and a limiting slide plate fixedly connected to the side wall of the storage box and slidably connected to the partition plates.

[0004] This product has a height adjustment function, which allows users to adjust the height of the transfer vehicle according to actual needs, making the use of the material transfer vehicle more user-friendly. However, it cannot be adjusted to the height of the unloading position as needed, which makes it inconvenient for workers to transport materials to higher places and increases the difficulty of the transfer.

[0005] Therefore, those skilled in the art have provided a material transfer trolley for construction to solve the problems mentioned in the background art. Utility Model Content

[0006] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a material transfer trolley for construction. The trolley uses a second servo motor in its lifting mechanism to drive a threaded rod to rotate. A moving block is threadedly connected to the threaded rod, and a support rod is hinged to the base and support platform. This allows the moving block to drive the support rod and move the support platform up and down, facilitating the transport of materials to higher locations and reducing the difficulty of material transfer for workers.

[0007] To achieve the above objectives, the present invention provides the following technical solution: A material transfer trolley for construction includes a base, an adjustment mechanism, a drive mechanism, and a lifting mechanism. The adjustment mechanism is located at the rear end of the base and includes an adjustment handle. The drive mechanism is located at the lower end of the base and includes a rotating rod. An electrical box is fixedly connected to the middle of the upper end of the base. The lifting mechanism is located at the upper end of the base and includes a connecting rod and a support platform. Support rods are hinged to the rear ends of both sides of the upper end of the base and the rear ends of both sides of the lower end of the support platform. The middle part of the outer wall of each support rod is hinged to the connecting rod. The front end of each support rod is fixedly connected to a moving block. A second servo motor is installed in the cavity at the middle of the front end of the power box. The output shaft of the second servo motor passes through the power box and is fixedly connected to a threaded rod. The outer wall of the threaded rod is threadedly connected to the moving block. Sliding grooves are opened at the front ends of both sides of the upper end of the base. The moving blocks are slidably connected to the sliding grooves. A rotating groove is opened at the middle of the front end of the base. Through the above technical solution, the threaded rod is driven to rotate by the second servo motor. The moving block is threadedly connected to the threaded rod and is connected to the support rod hinged to the base and the support platform. This allows the moving block, which slides inside the chute, to drive the support rod to move, enabling the support platform to move up and down, which facilitates the transport of materials to higher places.

[0008] Furthermore, a first servo motor is provided on the inner wall of the other side of the rotating groove. The output shaft of the first servo motor is fixedly connected to a drive gear. A driven gear is fixedly connected to the middle of the outer wall of the rotating rod. The driven gear meshes with the drive gear. Both sides of the rotating rod pass through the base and are fixedly connected to drive wheels. The above technical solution uses a first servo motor to drive the active gear to rotate. The driven gear fixedly connected to the rotating rod meshes with the active gear, so that the driven gear drives the rotating rod to rotate, thereby providing assistance to the workers when transferring raw materials.

[0009] Furthermore, a fixing rod is fixedly connected to the outer wall of the rear end of the base. A moving groove is provided on the upper ends of both sides of the outer wall of the rear end of the fixing rod. An adjustment groove is provided on both sides of the upper end of the fixing rod. A return spring is fixedly connected to the inner wall of the rear end of the moving groove. Multiple slots are provided on both sides of the outer wall of the rear end of the adjustment handle. A PLC control panel is fixedly connected to the middle of the adjustment handle. The above technical solution uses a reset spring inside the moving slot to act on the locking rod, which keeps the locking rod engaged with the locking slot on the adjusting handle, preventing the adjusting handle from sliding in the adjusting slot on the fixed rod. The PLC control panel on the adjusting handle allows the operator to control the operation of the equipment.

[0010] Furthermore, each of the four corners of the upper end of the base is fixedly connected to a support column, a storage battery is installed in the cavity in the middle of the power box, and the front end of the threaded rod is rotatably connected to the base. Through the above technical solution, the four pillars fixedly connected to the upper part of the base can provide buffer and support when the support platform is lowered to the lowest position, reducing unnecessary impact. The battery installed inside the power box can power the equipment, allowing the second servo motor to drive the threaded rod to rotate, so that the moving block threadedly connected to the threaded rod can move along the inside of the slide groove opened on the base.

[0011] Furthermore, baffles are hinged to both sides of the lower end of the outer wall of the front end of the support platform, and the upper ends of the outer walls of both sides of the baffles are connected to the support platform by pins. The above technical solution allows the baffle, which is hinged to the support platform, to be opened by removing the pin, making it easier for workers to unload materials. Alternatively, the pin can be used to connect the baffle and the support platform together, making it less likely for raw materials inside the support platform to fall out.

[0012] Furthermore, guide rods are fixedly connected to the inner walls of both the front and rear ends of the chute, and the outer walls of the guide rods are slidably connected to the moving block. By using the above technical solution, the guide rod and the moving block that are fixedly connected inside the chute are slidably connected, making it less likely for the moving block to detach when it moves inside the chute, thus improving the safety of the platform's up and down movement.

[0013] Furthermore, both sides of the outer wall of the rotating rod are rotatably connected to the base, and the rear ends of both sides of the lower end of the base are fixedly connected to steering wheels; The above technical solution uses a first servo motor to drive the active gear, which in turn drives the drive wheel to rotate, providing additional power to the device. The steering wheel, which is fixedly connected to the lower end of the base, allows the device to turn and change its path.

[0014] Furthermore, each of the adjustment slots is slidably connected to the adjustment handle, and each of the front ends of the reset springs is fixedly connected to a locking rod. Each of the locking rods slides inside the moving slot, and the front end of each locking rod passes through the fixed rod and is engaged with the locking slot. The above technical solution allows the adjustment handle to move within the movable groove by pulling the lever, thereby releasing the locking connection of the groove on the adjustment handle. This enables the adjustment handle to move within the adjustment groove on the fixed rod, changing the height of the adjustment handle and allowing the operator to adjust the handle height according to actual usage needs.

[0015] This utility model has the following beneficial effects: 1. The present invention proposes a material transfer trolley for construction, which drives the threaded rod to rotate through the second servo motor in the lifting mechanism. The moving block is threadedly connected to the threaded rod and is connected to the support rod hinged to the base and the support platform. This allows the moving block, which slides inside the chute, to drive the support rod to move, so that the support platform can move up and down. This makes it easier for workers to transport materials to higher places and reduces the difficulty of material transfer for workers.

[0016] 2. The material transfer trolley for construction proposed in this utility model drives the drive gear to rotate through the first servo motor in the drive mechanism. The driven gear and the drive gear are meshed and connected by a driven gear fixedly connected on the rotating rod. Through the transmission of the driven gear, the rotating rod drives the drive wheel to rotate, thereby providing assistance to the workers when transferring construction materials, reducing the labor intensity of the workers, and further improving the handling efficiency.

Obviously, the described specific embodiments are only a part of the specific embodiments of the present invention, and not all of them. Based on the specific embodiments of the present invention, all other specific embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 7 The present invention provides a specific embodiment of a material transfer trolley for construction, comprising a base 1, an adjustment mechanism 2, a drive mechanism 3, and a lifting mechanism 7. The rear end of the base 1 is provided with the adjustment mechanism 2, which includes an adjustment handle 206. The lower end of the base 1 is provided with the drive mechanism 3, which includes a rotating rod 304. The middle part of the upper end of the base 1 is fixedly connected with an electrical box 5. The upper end of the base 1 is provided with the lifting mechanism 7, which includes a connecting rod 704 and a support platform 706. The rear ends of both sides of the upper end of the base 1 and the rear ends of both sides of the lower end of the support platform 706 are hingedly connected with support rods 705. The middle part of the outer wall of the support rod 705 is hinged to the connecting rod 704. The front end of the support rod 705 is fixedly connected to the moving block 703. The cavity in the middle of the front end of the power box 5 is provided with the second servo motor 701. The output shaft of the second servo motor 701 passes through the power box 5 and is fixedly connected to the threaded rod 702. The outer wall of the threaded rod 702 is threadedly connected to the moving block 703. The front ends of both sides of the upper end of the base 1 are provided with sliding grooves 708. The moving blocks 703 are slidably connected to the sliding grooves 708. The middle of the front end of the base 1 is provided with a rotating groove 301.

[0021] A fixed rod 201 is fixedly connected to the outer wall of the rear end of the base 1. Movable grooves 203 are provided on the upper ends of both sides of the outer wall of the rear end of the fixed rod 201. Adjustment grooves 202 are provided on both sides of the upper end of the fixed rod 201. Return springs 204 are fixedly connected to the inner walls of the rear ends of the movable grooves 203. Multiple locking slots 207 are provided on both sides of the outer wall of the rear end of the adjustment handle 206. A PLC control panel 8 is fixedly connected to the middle of the adjustment handle 206. The return springs 204 inside the movable grooves 203 act on the locking rod 205, ensuring that the locking rod 205 remains engaged with the locking slots 207 on the adjustment handle 206, preventing the adjustment handle 206 from sliding within the adjustment grooves 202 on the fixed rod 201. The PLC control panel 8 on the adjustable handle 206 facilitates operator control of the equipment's operating status. Support pillars 4 are fixedly connected to the four corners of the upper end of the base 1. A battery 6 is installed in the cavity inside the power box 5. The front end of the threaded rod 702 is rotatably connected to the base 1. The four support pillars 4 fixedly connected to the upper end of the base 1 provide cushioning and support when the support platform 706 descends to its lowest position, reducing unnecessary impact. The battery 6 inside the power box 5 provides power to the equipment, enabling the second servo motor 701 to drive the threaded rod 702 to rotate, allowing the moving block 703, threadedly connected to the threaded rod 702, to move along the interior of the groove 708 on the base 1. Both sides of the lower end of the front outer wall of the support platform 706 are hinged to baffles 707. The upper ends of the outer walls of both sides of the baffles 707 are connected to the support platform 706 by pins. By removing the pins, the baffles 707 hinged to the support platform 706 can be opened, facilitating material unloading by the operator. The pins can also be used to connect the baffles 707 and the support platform 706 together, preventing the raw materials inside the support platform 706 from falling out. The inner walls of the front and rear ends of the chute 708 are fixedly connected to guide rods 709. The outer walls of the guide rods 709 are slidably connected to the moving block 703. By allowing the guide rods 709 fixedly connected inside the chute 708 to slide and connect with the moving block 703, the moving block 703 can move within the chute. When moving within 708, it is not easy to detach, improving the safety of the up-and-down movement of the support platform 706. The adjustment grooves 202 are all slidably connected to the adjustment handles 206. The front end of the return springs 204 is fixedly connected to the locking rods 205. The locking rods 205 slide inside the moving grooves 203. The front end of the locking rods 205 passes through the fixed rods 201 and is engaged with the locking grooves 207. By pulling the locking rods 205 to move inside the moving grooves 203, the engagement with the locking grooves 207 on the adjustment handles 206 is released, allowing the adjustment handles 206 to move within the adjustment grooves 202 on the fixed rods 201, changing the height of the adjustment handles 206, so that the staff can adjust the height of the handle according to the actual usage needs.

[0022] Reference Figure 1 , Figure 2 , Figure 3 and Figure 6 A first servo motor 302 is installed on the inner wall of the other side of the rotating groove 301. The output shaft of the first servo motor 302 is fixedly connected to the drive gear 303. A driven gear 305 is fixedly connected to the middle of the outer wall of the rotating rod 304. The driven gear 305 meshes with the drive gear 303. Both sides of the rotating rod 304 pass through the base 1 and are fixedly connected to the drive wheel 306. Both sides of the outer wall of the rotating rod 304 are rotatably connected to the base 1. The rear ends of both sides of the lower end of the base 1 are fixedly connected to the steering wheel 307. The first servo motor 302 drives the drive gear 303, which is then transmitted through the driven gear 305, so that the rotating rod 304 drives the drive wheel 306 to rotate, providing additional power to the equipment. The steering wheel 307 fixedly connected to the lower end of the base 1 allows the equipment to turn and change its movement path.

[0023] Working principle: When using the construction material transfer trolley, the worker can first pull the lever 205 to move it inside the moving slot 203, releasing the engagement with the slot 207. If necessary, adjust the height of the adjusting handle 206 to a suitable position. Then, use the elasticity of the return spring 204 to restore the lever 205 to the engagement state with the other slot 207, and fix the position of the adjusting handle 206. After that, use the battery 6 installed in the power box 5 to power the equipment, remove the plug, open the baffle 707, place the construction materials on the support platform 706, and then close the baffle 707. Secondly, the staff starts the first servo motor 302 through the PLC control panel 8 to drive the drive gear 303 to rotate. After being driven by the driven gear 305, the rotating rod 304 drives the drive wheel 306 to rotate, thereby providing assistance for the staff to transfer raw materials. In conjunction with the steering wheel 307, the staff can turn the wheel and transfer the raw materials to the required position. Finally, the staff used the second servo motor 701 to drive the threaded rod 702 to rotate. The moving block 703 was threadedly connected to the threaded rod 702, and the support rod 705 was hinged to the base 1 and the bearing platform 706. This caused the moving block 703 to move along the slide 708, which in turn caused the support rod 705 to move, change the angle, and adjust the height of the bearing platform 706 to adapt to the high unloading position and carry out the unloading operation.
