Description

Technical Field

[0001] This utility model relates to the field of construction engineering technology, and more specifically, it relates to a material hoisting device for construction engineering. Background Technology

[0002] Lifting equipment refers to the general term for the installation and positioning of equipment by cranes or hoisting mechanisms. In the construction process, lifting equipment is needed to lift workpieces, tools or materials to change their position. Lifting equipment can lift components or structures that have been prefabricated in the factory or on the construction site and move them to a designated height so that workers can easily pick them up or carry them out.

[0003] Most existing hoisting equipment uses ropes. Because ropes have a large degree of freedom, they are prone to tilting when the weights of the loads at both ends of the hoisting equipment are different, resulting in poor safety performance when the material is rising.

[0004] Furthermore, the existing hoisting equipment has a relatively simple structure, with most of it relying solely on hooks. However, this structure is not suitable for hoisting materials that cannot be suspended, requiring the use of other tools and affecting hoisting efficiency. Summary of the Invention

[0005] To address the problems existing in the prior art, this utility model provides a material hoisting device for construction engineering, which solves the technical problem mentioned in the background art that most existing hoisting devices rely on ropes. Due to the large degree of freedom of ropes, tilting is prone to occur when the weights of the objects being hoisted at both ends of the hoisting device are inconsistent.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a material hoisting device for construction engineering, comprising a hoisting beam, guide rails fixedly provided on the upper end face and both sides of the hoisting beam, movable blocks slidably provided on each guide rail, ropes provided at the upper ends of each movable block, fixed blocks provided on both sides of the guide rails and on the upper end face of the hoisting beam, threaded rods rotatably provided at the middle position of each fixed block, each threaded rod being threadedly connected to a movable block, a first motor provided at one end of each threaded rod and on the outer wall of each fixed block, lifting blocks provided at the upper ends of the two ropes, T-slots provided on the lower end face and both sides of the hoisting beam, T-blocks slidably provided inside each T-slot, cylinders provided at the lower ends of each T-blocks, and hooks provided at the output ends of each cylinder.

[0007] The present invention is further configured such that a lower clamping plate is fixedly provided on the outer wall of the hook at the upper end, a connecting rod is fixedly provided on the lower end face of the lifting beam at the middle position, a top plate is provided at the bottom of the connecting rod, and an electric push rod is provided on the lower end face of the top plate at both the front and rear sides. A support block is fixedly provided at the output end of the electric push rod to facilitate clamping and fixing of materials.

[0008] The present invention is further provided with anti-slip pads on the inner wall of the support block, which facilitates increasing the friction between the material and the support block.

[0009] The present invention is further configured such that the lower end of the lifting block is provided with a base, the upper end surface of the base is fixedly provided with a support beam, the support beam is provided with a sliding groove, the lifting block is slidably installed with the sliding groove, a fixed pulley is rotatably provided on the inner wall of the sliding groove and located at the upper end, and a hanging rope is fixedly provided at the upper end of the lifting block, the other end of the hanging rope passes through the fixed pulley and extends to the bottom of the support beam, so as to facilitate the adjustment of the height of the lifting block.

[0010] The present invention is further provided that a mounting frame is provided on the outer wall of the support beam and at the bottom, and a winding roller is rotatably provided inside the mounting frame. The other end of the lifting rope is connected to the winding roller, so as to facilitate the lifting rope being wound on the surface of the winding roller.

[0011] The present invention is further provided with a second motor at one end of the winding roller and on the outer wall of the mounting frame, so as to facilitate the rotation of the winding roller.

[0012] The present invention is further configured such that each of the T-slots is provided with a lead screw for rotation, and each lead screw is threadedly connected to the T-block. Each of the two ends of the lifting beam is provided with a third motor, and the output end of the third motor is fixedly connected to the lead screw, so as to facilitate the adjustment of the distance between the hook and the lower clamping plate.

[0013] The present invention is further provided that the base has an external connection hole, which facilitates fixing the device to the ground.

[0014] Compared with the prior art, this utility model provides a material hoisting equipment for construction projects, which has the following beneficial effects:

[0015] By setting up guide rails, moving blocks, ropes, and threaded rods, users can control the first motor to move the threaded rods to drive the moving blocks, thereby adjusting the position of the bottom of the ropes and adjusting the balance of both ends of the lifting beam to keep it in a horizontal state, facilitating the lifting of materials and preventing slippage.

[0016] By setting up T-blocks, cylinders, hooks, lower clamps, and support blocks, materials or workpieces that need to be suspended can be fixed by hooks when hoisting. When hoisting workpieces that cannot be suspended, the workpiece can be placed on the upper end of the lower clamp, then the cylinder is controlled to raise the lower clamp and make the upper end of the workpiece contact the lower end of the top plate. Finally, the electric push rod is controlled to make the support blocks abut against the two sides of the workpiece to fix it, which facilitates subsequent hoisting.

[0017] By setting up a lifting rope, a fixed pulley, and a winding roller, the user can control a second motor to rotate the winding roller, causing the lifting rope to wind around the surface of the winding roller, thereby driving the lifting block to move upward and achieving the lifting effect. This facilitates the lifting of materials during construction projects and makes the equipment easy to use. Attached Figure Description

[0029] More specifically, the user can control the first motor 7 to move the threaded rod 6 to move the moving block 3, thereby adjusting the position of the bottom of the rope 4 and adjusting the balance of both ends of the lifting beam 1 to make it horizontal, which facilitates the lifting of materials and prevents slippage. When lifting materials or workpieces that need to be suspended, they can be fixed by the hook 12. When lifting workpieces that cannot be suspended, the workpiece can be placed on the upper end of the lower clamping plate 13, and then the cylinder 11 is controlled to raise the lower clamping plate 13 and make the upper end of the workpiece contact the lower end surface of the top plate 15. Finally, the electric push rod 16 is controlled to make the support block 17 abut against the two sides of the workpiece to fix it and facilitate subsequent lifting.

[0030] Please see Figure 2 and Figure 5As an implementation method for adjusting the height of the lifting block 8: the lower end of the lifting block 8 is provided with a base 19, the upper end surface of the base 19 is fixedly provided with a support beam 20, the support beam 20 is provided with a sliding groove 21, the lifting block 8 is slidably installed with the sliding groove 21, the inner wall of the sliding groove 21 is rotatably provided with a fixed pulley 22 at the upper end, the upper end of the lifting block 8 is fixedly provided with a suspension rope 23, the other end of the suspension rope 23 passes through the fixed pulley 22 and extends to the bottom of the support beam 20, the outer wall of the support beam 20 is provided with a mounting frame at the bottom, the inside of the mounting frame is provided with a winding roller 24, the other end of the suspension rope 23 is connected to the winding roller 24, one end of the winding roller 24 is provided with a second motor 25 on the outer wall of the mounting frame, and the base 19 is provided with an external connection hole 28.

[0031] Specifically, the user can control the second motor 25 to rotate the winding roller 24, so that the lifting rope 23 is wound around the surface of the winding roller 24, thereby driving the lifting block 8 to move upward, thus achieving the lifting effect, which is convenient for lifting materials during the construction process and is easy to use.

[0034] In summary, when using the overall equipment: when hoisting materials or workpieces that need to be suspended, they can be fixed using hooks 12. When hoisting workpieces that cannot be suspended, the workpiece can be placed on the upper end of the lower clamping plate 13 first, then the cylinder 11 is controlled to raise the lower clamping plate 13 and make the upper end of the workpiece contact the lower end surface of the top plate 15.

Then, the second motor 25 is controlled to rotate the winding roller 24 so that the hoisting rope 23 is wound around the surface of the winding roller 24, thereby driving the lifting block 8 to move upward, thus achieving the hoisting effect. This facilitates the lifting of materials during construction projects. When the hoisting beam 1 becomes skewed, the user can control the first motor 7 to move the threaded rod 6 to move the moving block 3 to adjust the position of the bottom of the rope 4, thereby adjusting the balance of both ends of the hoisting beam 1 to make it level, facilitating the hoisting of materials and preventing slippage.
