Description

Technical Field

[0001] This utility model relates to the field of material lifting technology, and in particular to a material lifting mechanism for construction engineering. Background Technology

[0002] Construction engineering is a comprehensive field involving a series of activities such as the construction, renovation, and expansion of buildings and structures. With the development of society, material handling mechanisms are often used in the vertical transportation of building materials and small equipment.

[0003] Existing technologies, such as the utility model patent with publication number CN212740459U, disclose a construction material hoist, belonging to the field of hoist technology. It solves the problem of insufficient stability in existing products. The construction material hoist includes a hoist and a base. The hoist is mounted on the base, and four wheels are installed at the bottom of the base. Four support blocks are fixedly connected to the base, and each of the four support blocks is provided with an adjusting screw threaded to it. A handwheel is fixedly connected to the upper end of each of the four adjusting screws, and a support plate is rotatably connected to the bottom of each of the four adjusting screws. Multiple gripping mechanisms are provided at the bottom of each of the four support plates. This utility model can be used for construction material hoists.

[0004] Currently, most construction material hoists use ropes to lift the placement frame. However, during operation, the ropes are prone to wear. When the rope breaks, the placement frame along with the material can easily fall directly, impacting the bottom of the equipment and causing damage to both the material and the equipment, increasing the producer's economic losses. This needs to be improved. Utility Model Content

[0005] The purpose of this utility model is to solve the problem that in the existing technology, most material hoists for construction projects often use ropes to lift the placement frame. However, during operation, the ropes are prone to wear. When the rope breaks, the placement frame and the material can easily fall directly, impacting the bottom of the equipment and causing damage to both the material and the equipment, thus increasing the economic losses of the producer. Therefore, this utility model proposes a material hoisting mechanism for construction projects.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a material lifting mechanism for construction engineering, comprising a frame, a placement frame placed inside the frame, a guide sleeve fixedly connected to the surface of the placement frame, the guide sleeve being slidably connected to the surface of the frame, a clamp fixedly connected to the upper surface of the frame, a control motor installed inside the clamp, a winding wheel fixedly connected to the drive end of the control motor, a through hole opened on the upper surface of the frame, a steel wire rope fixedly connected to the winding wheel, a sliding sleeve fixedly connected to the surface of the placement frame, a pulling frame slidably connected in the sliding sleeve, and the end of the steel wire rope away from the winding wheel being connected to the pulling frame. The frame is fixedly connected to the surface. The inner wall of the guide sleeve has two symmetrically arranged sliding grooves, in which sliders are slidably connected. A protective plug is fixedly connected to one side of the two sliders that are close to each other. A protective protrusion is fixedly connected to the inner wall of the frame. A pull rope is fixedly connected to the lower surface of the pull frame. One end of the pull rope is fixedly connected to the surface of the protective plug. This solution uses protective protrusions and protective plugs to effectively prevent the placement frame from falling continuously when the wire rope breaks, reducing safety hazards during equipment operation, protecting materials and equipment, reducing the probability of equipment and material damage, reducing economic losses for producers, and facilitating normal use of the equipment.

[0007] Preferably, the number of guide sleeves is two, and the two guide sleeves are arranged in a mirror image.

[0008] Preferably, the surface of the frame is fixedly connected with a protrusion, which is located below the placement frame.

[0009] Preferably, a spring is fixedly connected to the surface of the protective insert, and the end of the spring away from the protective insert is fixedly connected to the surface of the placement frame. When the material is lifted, if the wire rope breaks and the pulling frame loses its tension and falls, the spring will push the protective insert into the protective protrusion, thus ensuring the safety of the equipment.

[0010] Preferably, the surface of the placement frame is equipped with guide wheels, and one end of the pull rope rests on the guide wheels. When transporting materials, the materials are placed in the placement frame, and then the control motor drives the winding wheel to rotate. The winding wheel then winds up the wire rope, and the pulling frame moves upward. The pulling frame pulls the protective plug through the pull rope, and the spring deforms under force. When the lower end of the pulling frame abuts against the sliding sleeve, the pulling frame, together with the sliding sleeve, lifts the placement frame. After the material handling operation is completed, the control motor and the winding wheel are operated to lower the pulling frame again. After the placement frame contacts the ground, the spring pushes the protective plug into the protective protrusion, ensuring that the placement frame is in a stable state and facilitating the placement of materials.

[0011] Preferably, the lower end of the pull frame is L-shaped to prevent the pull frame from detaching from the sliding sleeve.

[0012] Preferably, there are multiple protective protrusions, and the multiple protective protrusions are arranged at equal intervals to facilitate the normal use of the equipment.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] In this invention, when transporting materials, the materials are placed in the placement frame. The control motor then drives the winding wheel to rotate, which in turn winds up the wire rope. The pulling frame then moves upward, pulling the protective insert via a rope. The spring deforms under pressure. When the lower protrusion of the pulling frame abuts against the sliding sleeve, the pulling frame, in conjunction with the sliding sleeve, lifts the placement frame. After the material handling operation is complete, the control motor and winding wheel lower the pulling frame again. Once the placement frame contacts the ground, the spring pushes the protective insert into the protective protrusion, ensuring the placement frame is stable and facilitating material placement. If the wire rope breaks while lifting materials, the pulling frame loses its tension and falls. The spring then pushes the protective insert into the protective protrusion, ensuring equipment safety. This solution, using protective protrusions and protective inserts, effectively prevents the placement frame from falling continuously when the wire rope breaks, reducing safety hazards during equipment operation, protecting materials and equipment, reducing the probability of equipment and material damage, minimizing economic losses for producers, and facilitating normal equipment use.

[0022] Please see Figures 1-5 This utility model provides a technical solution: a material lifting mechanism for construction engineering, including a frame 1, a placement frame 3 placed inside the frame 1, a guide sleeve 4 fixedly connected to the surface of the placement frame 3, the guide sleeve 4 being slidably connected to the surface of the frame 1, a clamp 8 fixedly connected to the upper surface of the frame 1, a control motor 7 installed inside the clamp 8, a winding wheel 9 fixedly connected to the drive end of the control motor 7, a through hole 10 opened on the upper surface of the frame 1, a steel wire rope 6 fixedly connected to the winding wheel 9, a sliding sleeve 12 fixedly connected to the surface of the placement frame 3, a pulling frame 5 slidably connected in the sliding sleeve 12, and the end of the steel wire rope 6 away from the winding wheel 9 being fixedly connected to the surface of the pulling frame 5. The inner wall of the guide sleeve 4 has two symmetrically arranged sliding grooves 18, in which sliders 17 are slidably connected. Protective inserts 15 are fixedly connected to the side of the two sliders 17 that are close to each other. Protective protrusions 11 are fixedly connected to the inner wall of the frame 1. Pull ropes 14 are fixedly connected to the lower surface of the pull frame 5. One end of the pull rope 14 is fixedly connected to the surface of the protective inserts 15. This scheme uses protective protrusions 11 and protective inserts 15 to effectively prevent the placement frame 3 from falling continuously when the wire rope 6 breaks, reducing safety hazards during equipment operation, protecting materials and equipment, reducing the probability of equipment and material damage, reducing economic losses for producers, and facilitating normal use of the equipment.

[0023] Specifically, there are two guide sleeves 4, which are set up in a mirror image.

[0024] Specifically, a protrusion 2 is fixedly connected to the surface of the frame 1, and the protrusion 2 is located below the placement frame 3.

[0025] In this embodiment: A spring 16 is fixedly connected to the surface of the protective plug 15. The end of the spring 16 away from the protective plug 15 is fixedly connected to the surface of the placement frame 3. When the material is lifted, the wire rope 6 breaks and the pulling frame 5 loses its tension and falls. Then the spring 16 pushes the protective plug 15 into the protective protrusion 11 to ensure the safety of the equipment.

[0026] In this embodiment: a guide wheel 13 is installed on the surface of the placement frame 3, and one end of the pull rope 14 is placed on the guide wheel 13. When transporting materials, the materials are placed in the placement frame 3, and then the operation control motor 7 drives the winding wheel 9 to rotate. The winding wheel 9 then winds up the wire rope 6, and the pulling frame 5 moves upward. The pulling frame 5 pulls the protective plug 15 through the pull rope 14. The spring 16 deforms under force. When the lower end of the pulling frame 5 abuts against the sliding sleeve 12, the pulling frame 5, together with the sliding sleeve 12, lifts the placement frame 3. After the material handling operation is completed, the operation control motor 7 and the winding wheel 9 lower the pulling frame 5 again. After the placement frame 3 contacts the ground, the spring 16 pushes the protective plug 15 to insert into the protective protrusion 11, ensuring that the placement frame 3 is in a stable state, which is convenient for placing materials.

[0027] Specifically, the lower end of the pull frame 5 is L-shaped to prevent the pull frame 5 from detaching from the sliding sleeve 12.

[0028] Specifically, there are multiple protective protrusions 11, which are arranged at equal intervals to facilitate the normal use of the equipment.

[0029] Working principle: When transporting materials, the materials are placed in the placement frame 3. Then, the control motor 7 drives the winding wheel 9 to rotate, which in turn winds up the wire rope 6. The pulling frame 5 then moves upward, pulling the protective plug 15 through the pull rope 14. The spring 16 deforms under force. When the lower protrusion of the pulling frame 5 abuts against the sliding sleeve 12, the pulling frame 5, in conjunction with the sliding sleeve 12, lifts the placement frame 3. After the material handling operation is completed, the control motor 7 and the winding wheel 9 lower the pulling frame 5 again. After the placement frame 3 contacts the ground, the spring 16 pushes the protective plug 15. The protective protrusion 11 is inserted to ensure that the placement frame 3 is in a stable state, facilitating the placement of materials. When the material is being lifted, if the wire rope 6 breaks, the pulling frame 5 will lose tension and fall. Subsequently, the spring 16 will push the protective insert 15 into the protective protrusion 11 to ensure the safety of the equipment. This solution uses the protective protrusion 11 and the protective insert 15 to effectively prevent the placement frame 3 from falling continuously when the wire rope 6 breaks, reducing safety hazards during equipment operation, protecting materials and equipment, reducing the probability of equipment and material damage, reducing economic losses for producers, and facilitating the normal use of the equipment.
