[0002] Prefabricated construction is a building method that involves manufacturing and pre-assembling materials in a factory environment. It involves producing precast concrete wall panels, prefabricated steel structures, precast walls, prefabricated staircases, and other structural components in a factory and then assembling them on-site. Compared to traditional on-site construction, this method saves time and costs. It can be applied to the construction of various types of buildings, including residential, commercial, office, school, and hotel buildings. Furthermore, many modules in prefabricated construction are recyclable and reusable, making it environmentally friendly. Prefabricated building materials are typically lifted by tower cranes during on-site assembly.

The fastening module includes a protective cylinder mounted on the base, a drive motor mounted inside the protective cylinder, and a pressing plate connecting the drive motor and the tower crane body. The tower crane can supply materials and drive the building materials to rotate, enabling the building materials to move to a designated area.

[0004] Existing building material lifting devices have a slow lifting speed for building materials, which affects the assembly of building materials, reduces construction efficiency, and has a high risk factor, making collisions very easy. Summary of the Invention

[0005] In view of this, the present invention provides a building material lifting device for green prefabricated building construction, which can solve the problems of slow lifting speed of existing building material lifting devices, which affect the assembly of building materials, affect construction efficiency, have a high risk factor, and are prone to collisions.

[0006] This invention is implemented as follows:

[0007] This invention provides a building material lifting device for green prefabricated building construction, comprising a lifting assembly and a tower crane. The lifting assembly is used to lift and lower building materials, and the tower crane provides support for the lifting assembly. The lifting assembly includes a guide rail, a building material rack, a connector, and a drive component. The tower crane includes a tower body, a boom, a carriage, and hooks. Two hooks are included; one hook is connected to the lifting assembly, and the bottom of the other hook is fixedly connected to a monitoring system. The monitoring system is used to monitor the lifting and lowering of the building materials by the lifting assembly in real time. The monitoring system includes a connecting arm, a three-dimensional rotation motor, and a camera. One end of the connecting arm is fixedly connected to the hook, and the other end of the connecting arm is fixedly connected to the camera via the three-dimensional rotation motor. The three-dimensional rotation motor drives the camera to rotate in three dimensions, and the connecting arm is used to fix the camera to the tower crane. The hook with the monitoring system is fixed at the shorter end of the boom and tower body, thus separating the positions of the two hooks.

[0008] The technical advantages of the building material lifting device for green prefabricated building construction provided by this invention are as follows: By setting up a lifting component, building materials can be quickly lifted and lowered to a specified height; by using a tower crane, the lifted building materials can be moved to a designated area, saving the time of lifting and lowering building materials by the tower crane, and effectively utilizing the tower crane to move and rotate building materials, so that the building materials can be moved to a preset position, which can effectively shorten the construction time of prefabricated buildings and complete the construction task within the specified time; by setting up a monitoring system, the problem of high risk factor and easy collision of existing building material lifting devices can be solved, and the construction site can be monitored in real time.

[0009] Based on the above technical solution, the building material lifting device for green prefabricated building construction of the present invention can be further improved as follows:

[0010] The three-dimensional rotation motor includes a translation axis motor at the bottom of a connecting arm, a rotating arm fixedly connected to the bottom of the translation axis motor, a roll axis motor fixedly connected to the other end of the rotating arm, a U-shaped frame connected to the output shaft of the roll axis motor, a pitch axis motor at one end of the U-shaped frame, and a fixed shaft at the other end of the U-shaped frame; the camera has a square structure, and through holes are provided on two side walls of the camera, one of which is connected to the rotating shaft of the pitch axis motor, and the other is connected to the fixed shaft;

[0011] The camera is equipped with heat dissipation louvers on its side wall.

[0012] Furthermore, the guide rail is disposed on one side of the tower crane, the building material rack is slidably connected to the guide rail, and the building material rack has an internal cavity for accommodating building materials; the connector is movably connected to the building material rack for connecting the building materials; the driving component is connected to the guide rail and the building material rack for driving the building material rack to rise and fall on the guide rail.

[0013] The boom is movably connected to the tower body, the slide is slidably connected to the boom along the length of the boom, and the hook is connected to the slide; the slide and the boom are slidably connected by rollers, and a wire rope passes through the hook, which is controlled by a winch fixed to the boom.

[0014] Furthermore, one end of the building material rack has a notch, which is arranged along the direction of the sliding channel and passes through the building material rack on the side where the building material slides away from the building material rack. The building material rack is provided with fixing blocks, which are located on both sides of the notch. Fixing grooves are provided on the opposite sides of the two fixing blocks, and the fixing grooves pass through the fixing blocks along the direction where the building material slides away from the building material rack. The two sides of the connector are slidably inserted into the fixing grooves, and the connector forms a hook interface for hooking with the hook.

[0015] The number of guide rails is multiple, and the lifting assembly also includes two first magnetic suction parts. The two first magnetic suction parts are distributed at intervals along a direction perpendicular to the guide rails. The first magnetic suction parts are connected to the guide rails. The tower crane also includes two second magnetic suction parts. The two second magnetic suction parts are arranged one-to-one with the first magnetic suction parts. The second magnetic suction parts are connected to the hook and can magnetically attract the first magnetic suction parts.

[0016] The first magnetic attraction part and the second magnetic attraction part can be permanent magnets or electromagnets. Preferably, the first magnetic attraction part is a permanent magnet and the second magnetic attraction part is an electromagnet.

[0017] By setting the first magnetic attraction part and the second magnetic attraction part, the hook can be fixed and limited during the connection process between the hook and the connecting part, so that the lifting connecting part can automatically connect to the hook without manual connection between the hook and the connecting part.

[0018] Furthermore, the fixing block has an opening on one side in the horizontal direction, and one side of the hook is a slope; the lifting assembly also includes a plurality of clamping members, each clamping member corresponding to one of the fixing blocks. Each clamping member includes a clamping plate and a first elastic part. The clamping plate is positioned relative to the horizontal opening of the fixing block. The bottom of the clamping plate is hinged to the fixing block. The clamping plate and the fixing block together form the fixing groove. One end of the first elastic part is connected to the top of the clamping plate, and the other end is connected to the fixing block, for providing elastic force for the clamping plate to return to its original position after rotation.

[0019] The guide rail includes multiple guide segments and a fixing member. The multiple guide segments are arranged sequentially along the guide. One end of each guide segment has a fixing hole, and the other end of each guide segment has a corresponding protrusion relative to the fixing hole. The protrusion is inserted into an adjacent fixing hole. The fixing member is disposed between two adjacent guide segments for detachable connection of the two adjacent guide segments.

[0020] The first elastic part can be a spring, an elastic strip, or an elastic block, etc.

[0021] Adjacent guide sections can be detachably connected using bolts, bolts and nuts, or clips.

[0022] The protrusion can have a cross-section that is circular, polygonal, or similar.

[0023] Furthermore, the fastener includes two connecting posts, a bolt, and a nut. The two connecting posts are respectively connected to two adjacent guide sections. The two connecting posts are respectively provided with a first mounting hole and a second mounting hole. The second mounting hole is coaxially arranged with the first mounting hole. The threaded end of the bolt passes through the first mounting hole and the second mounting hole. The nut is threadedly connected to the threaded end of the bolt.

[0024] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: by setting a fixing component, when it is necessary to connect adjacent guide sections, the connecting posts of adjacent guide sections are aligned, then the bolts are passed through the two connecting posts of the two adjacent guide sections, and then the nuts are threadedly connected to the threaded ends of the bolts, thus realizing the detachable connection of adjacent guide sections.

[0025] Furthermore, the building material rack includes a fixed box, sliding frames, end plates, and a second linear drive unit. There are two sliding frames and two end plates, and multiple second linear drive units. The fixed box has openings at its top and both ends. Two sliding frames are slidably disposed at the two open ends of the fixed box, and the sliding frames are slidably connected to the fixed box. Each end plate corresponds to one of the sliding frames, and each end plate is disposed on the side of a sliding frame away from the other sliding frame. One side of the end plate is hinged to the sliding frame, and the other end is movably connected to the sliding frame. The fixed end of the second linear drive unit is connected to the sliding frame, and the movable end is hinged to the fixed box. The fixed box has a notch, and multiple fixing blocks are located on both sides of the notch and connected to the fixed box.

[0026] The building material rack also includes multiple sliding sleeves and second rollers. The sliding sleeves are arranged in a one-to-one correspondence with the guide rails. The sliding sleeves are sleeved on the guide section and fixedly connected to the fixed box. The sliding sleeves have a fixing opening relative to the position of the connecting column. Multiple second rollers are built into the sliding sleeves and the second rollers roll against the guide section.

[0027] The sliding frame and the fixed box can be slidably connected by a slide rail, slider, or guide rod. The other side of the end plate can be detachably connected to the sliding frame by screws, bolts, or pins.

[0028] The fixed box, two sliding frames, and two end plates together form an adjustable-length receiving area that can accommodate building materials of different lengths. The end doors can be opened as needed to accommodate longer building materials, and opening the end doors allows building materials to enter the receiving area through the end doors.

[0029] The sliding connection between the fixed box and the guide section is achieved by setting a sliding sleeve, and the sliding damping between the sliding sleeve and the guide section is reduced by setting a second roller.

[0030] Furthermore, the connector includes a lifting block, a connecting rope, and a lifting ring. There are multiple connecting ropes and lifting rings. The two sides of the lifting block are slidably inserted into the fixing grooves of the two fixing blocks. The lifting block has the hanging interface opened along the direction of the notch. One end of the multiple connecting ropes is connected to the lifting block. The lifting ring is set one-to-one with the connecting rope. The lifting ring is threadedly connected to the building material.

[0031] The guide rail also includes multiple connecting rods, one end of which is connected to the guide section.

[0032] The beneficial effects of adopting the above-mentioned improved scheme are as follows: when the lifting block is raised and lowered with the fixed box, the lifting block first contacts the hook, the lifting block contacts the inclined surface of the hook and rotates under the action of the inclined surface of the hook until the hook passes through the hanging interface and the lifting block, thus realizing the connection between the hook and the connecting piece; by setting the connecting rope and multiple lifting rings, the connection between the lifting block and the building material can be realized.

[0033] The connecting rod can be anchored to the building using bolts or other fasteners, or it can be connected using building adhesives. The connecting rod and the guide section can be connected by hinges, threads, or snap-fits.

[0034] By setting up connecting rods, the guide section is connected to the building, which can prevent the guide section from tilting or bending when subjected to external forces, thus achieving a stable connection between the guide section and the building.

[0035] Furthermore, the lifting assembly also includes multiple reinforcing members, which are distributed at guide intervals along the guide rail, and the reinforcing members are connected to multiple guide segments;

[0036] The reinforcement component includes a reinforcing beam and a reinforcing block. The reinforcing block corresponds one-to-one with the guide rail. One end of the reinforcing block is connected to the guide section. The reinforcing block is located on the side of the guide section away from the fixed box. The other end of the reinforcing block is connected to the reinforcing beam. The size of the reinforcing block is smaller than the size of the fixing opening.

[0037] The driving component includes a first winch and a first wire rope. The first winch is fixed on the guide rail, one end of the first wire rope is wound around the first winch, and the other end of the first wire rope is connected to the building material frame.

[0038] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: by setting multiple reinforcing members, which are connected to the guide sections in multiple guide rails, the connection strength between multiple guide sections can be strengthened.

[0039] Multiple reinforcing blocks and beams connect multiple guide rails together, which can enhance the structural strength of multiple guide rails.

[0040] The reinforcing blocks can be connected to the fixed beams and guide sections using bolts, screws, and clips.

[0041] Furthermore, the lifting assembly also includes a guide member, which includes a rotating frame, a first roller, and a first linear drive unit. The rotating frame is rotatably connected to the guide rail, and the first roller is rotatably connected to the rotating frame. The rotating frame has a fixed end and a telescopic end. The fixed end of the rotating frame is hinged to the guide rail, and the first linear drive unit is used to drive the rotating frame to rotate.

[0042] Compared with existing technologies, the beneficial effects of the building material lifting device for green prefabricated building construction provided by this invention are as follows: by setting up lifting components, building materials can be quickly lifted and lowered to a specified height; by using a tower crane, the lifted building materials can be moved to a designated area, saving the time of lifting and lowering building materials by the tower crane, and effectively utilizing the tower crane to move and rotate building materials, so that building materials can be moved to a preset position, which can effectively shorten the construction time of prefabricated buildings and complete the construction task within the specified time; by setting up a monitoring system, the problem of high risk factor and easy collision of existing building material lifting devices can be solved, and the construction site can be monitored in real time. When building materials need to be lifted or lowered, the building materials are placed in the receiving cavity of the building material rack. After being received, the connecting piece connects the building materials and is detachably connected to the building material rack. After being received, the drive unit is activated, which drives the building material rack to lift and lower along the guide rail. Because the building material rack has stable guide rails and support, the safety of lifting and lowering the building materials can be ensured, and the building materials can be lifted and lowered quickly. After the building materials are lifted and lowered to the preset position, the hook is detachably connected to the connecting piece, and the connection between the connecting piece and the building material rack is released. Then, the drive unit is activated, which controls the building material rack to descend. The weight of the building materials acts on the hook, and then through the sliding carriage, the carriage can drive the hook and building materials to move along the guide of the boom. By selecting the boom, the carriage can drive the hook and building materials to rotate in the horizontal plane, so that the hook can move the building materials to the preset position. When the building materials have moved to the preset position, the connection between the connecting piece and the hook is released, and then the building materials are spliced ​​together to construct the building through assembly.

Detailed Implementation

[0067] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0068] like Figure 1-21The diagram shows a structural schematic of a building material lifting device for green prefabricated building construction provided by the present invention. The device includes a lifting assembly 1 and a tower crane 2. The lifting assembly 1 is used to lift and lower building materials, and the tower crane 2 provides support for the lifting assembly 1. The lifting assembly 1 includes a guide rail 11, a building material rack 12, a connector 13, and a drive component 14. The tower crane 2 includes a tower body 21, a boom 22, a carriage 23, and hooks 24. Two hooks 24 are included; one hook 24 is connected to the lifting assembly 1, and the bottom of the other hook 24 is fixedly connected to a monitoring system 3. The monitoring system 3 is used for real-time monitoring of the lifting of building materials by the lifting assembly 1; the monitoring system 3 includes a connecting arm 31, a three-dimensional rotating motor 32, and a camera 33. One end of the connecting arm 31 is fixedly connected to the hook 24, and the other end of the connecting arm 31 is fixedly connected to the camera 33 through the three-dimensional rotating motor 32. The three-dimensional rotating motor 32 is used to drive the camera 33 to rotate in three dimensions, and the connecting arm 31 is used to fix the camera 33 to the tower crane 2; the hook 24 with the monitoring system 3 is fixed at the shorter position on one side of the fixing point between the boom 22 and the tower body 21, which is used to separate the positions of the two hooks 24.

[0069] In the above technical solution, the three-dimensional rotation motor 32 includes a translation axis motor 323 at the bottom of the connecting arm 31, a rotating arm 324 fixedly connected to the bottom of the translation axis motor 323, a roll axis motor 322 fixedly connected to the other end of the rotating arm 324, a U-shaped frame 325 connected to the output shaft of the roll axis motor 322, a pitch axis motor 321 at one end of the U-shaped frame 325, and a fixed shaft at the other end of the U-shaped frame 325; the camera 33 has a square structure, and through holes are opened on two side walls of the camera 33, one through hole is connected to the rotating shaft of the pitch axis motor 321, and the other through hole is connected to the fixed shaft;

[0070] The side wall of camera 33 is equipped with heat dissipation louvers.

[0071] Furthermore, in the above technical solution, the guide rail 11 is set on one side of the tower crane 2, the building material rack 12 is slidably connected to the guide rail 11, and the building material rack 12 has a cavity inside for accommodating building materials; the connector 13 is movably connected to the building material rack 12 for connecting building materials; the drive component 14 is connected to the guide rail 11 and the building material rack 12 for driving the building material rack 12 to rise and fall on the guide rail 11.

[0072] The boom 22 is movably connected to the tower body 21. The slide 23 is slidably connected to the boom 22 along the length of the boom 22. The hook 24 is connected to the slide 23. The slide 23 and the boom 22 are slidably connected by rollers. A wire rope passes through the hook 24. The wire rope is controlled by a winch fixed on the boom 22.

[0073] In use, when it is necessary to lift or lower building materials, the building materials are placed in the receiving cavity of the building material rack 12. After being received, the connecting piece 13 is connected to the building materials and detachably connected to the building material rack 12. After being received, the drive piece 14 is activated, and the drive piece 14 guides the building material rack 12 to lift or lower along the guide rail 11. Because the building material rack 12 has stable guidance and support from the guide rail 11, the safety of lifting or lowering the building materials can be ensured, and the building materials are lifted or lowered quickly. After the building materials are lifted or lowered to the preset position, the hook 24 is detachably connected to the connecting piece 13, and the connecting piece is released. The connection between connector 13 and building material rack 12 is established, and then drive component 14 is activated. Drive component 14 controls the building material rack 12 to descend. The gravity of the building material acts on hook 24, and then through sliding carriage 23, hook 24 and building material are moved along the guide of boom 22. Carriage 23 drives hook 24 and building material to rotate in the horizontal plane, so that hook 24 moves building material to a preset position. After the building material moves to the preset position, the connection between connector 13 and hook 24 is released, and then the building material is spliced ​​to construct the building through assembly.

[0074] Furthermore, in the above technical solution, a notch is provided at one end of the building material rack 12. The notch is set along the direction of the sliding channel and passes through the building material rack 12 along the side where the building material slides away from the building material rack 12. A fixing block 15 is provided on the building material rack 12. The fixing block 15 is located on both sides of the notch. Fixing grooves are provided on the opposite sides of the two fixing blocks 15. The fixing grooves pass through the fixing blocks 15 along the direction where the building material slides away from the building material rack 12. The two sides of the connector 13 are slidably inserted into the fixing grooves, and the connector 13 forms a hook interface 1311 for hooking with the hook 24.

[0075] The number of guide rails is multiple. The lifting assembly 1 also includes two first magnetic suction parts 16. The two first magnetic suction parts 16 are distributed at intervals along a direction perpendicular to the guide rail 11. The first magnetic suction parts 16 are connected to the guide rail 11. The tower crane 2 also includes two second magnetic suction parts 25. The two second magnetic suction parts 25 are arranged one-to-one with the first magnetic suction parts 16. The second magnetic suction parts 25 are connected to the hook and can magnetically attract the first magnetic suction parts 16.

[0076] In use, when it is necessary to connect the connector 13 and the hook 24, the building material rack 12 is raised and lowered. The building material rack 12 drives the connector 13 to rise and fall. When the connector 13 rises and falls to the preset height, the hook 24 is partially inserted into the fixing groove, so that the hook 24 is hooked with the hanging interface 1311 of the connector 13. At this time, the height of the building material rack 12 is lowered or the height of the hook 24 is raised. The hook 24 can drive the connector 13 to disengage from the fixing groove of the fixing block 15. Under the action of the hook 24, the building materials are driven to disengage from the building material rack 12, realizing the separation of the building materials from the building material rack 12, so that the hook 24 can drive the building materials to move in the vertical and horizontal directions.

[0077] Since both the tower body 21 and the guide rail 11 are fixed to the ground or building, the position of the tower body 21 relative to the guide rail 11 is fixed, which in turn fixes the position of the lifting assembly 1 and the tower crane 2. This allows the boom 22 to rotate to a preset position and the slide 23 to move to the preset position, enabling the hook 24 to move above the connector 13. Then, the hook 24 is controlled to descend. When the hook 24 descends close to the guide rail 11, the first magnetic attraction part 16 and the second magnetic attraction part 25 begin to function. The first magnetic attraction part 16 magnetically attracts the corresponding second magnetic attraction part 25. Through the magnetic attraction of the first magnetic attraction part... The first magnetic attraction part 16 and the second magnetic attraction part 25 fix and position the hook 24 relative to the guide rail 11, so that when the building material rack 12 is raised, the building material rack 12 drives the connector 13 to rise. When the connector 13 abuts against the hook 24, the raised connector 13 rotates relative to the hook 24 until the hook 24 is inserted into the hanging interface 1311 of the connector 13, realizing the hook 24 and the hanging interface 1311 of the connector 13. Then the building material rack 12 is lowered or the hook 24 is raised, so that the first magnetic attraction part 16 and the second magnetic attraction part 25 are separated. At this time, the hook 24 drives the building materials to separate from the building material rack 12 through the connector 13.

[0078] Furthermore, in the above technical solution, the fixing block 15 has an opening on one side in the horizontal direction, and the hook 24 has an inclined surface on one side; the lifting assembly 1 also includes a plurality of clamping members 19, which are arranged one-to-one with the fixing block 15. The clamping member 19 includes a clamping plate 191 and a first elastic part 192. The clamping plate 191 is arranged with an opening in the horizontal direction relative to the fixing block 15. The bottom of the clamping plate 191 is hinged to the fixing block 15. The clamping plate 191 and the fixing block 15 together form a fixing groove. One end of the first elastic part 192 is connected to the top of the clamping plate 191, and the other end is connected to the fixing block 15, which is used to provide the elastic force for the clamping plate 191 to return to its original position after rotation.

[0079] The guide rail 11 includes multiple guide sections 111 and a fixing member 112. The multiple guide sections 111 are arranged sequentially along the guide. One end of the guide section 111 is provided with a fixing hole, and the other end of the guide section 111 is provided with a matching protrusion 113 relative to the fixing hole. The protrusion 113 is inserted into the adjacent fixing hole. The fixing member 112 is provided between two adjacent guide sections 111 for detachably connecting the two adjacent guide sections 111.

[0080] When the lifting connector 13 abuts against the inclined surface of the hook 24, the connector 13 can rotate relative to the fixed block and push the clamping plate 191 to rotate until the hook 24 passes through the hanging interface 1311 of the connector 13. At this time, the clamping plate 191 is reset under the elastic force of the first elastic part 192.

[0081] When it is necessary to connect the connector 13 on the building material rack 12 via the hook 24, the height of the hook 24 is lowered so that the hook 24 moves to the preset position until the first magnetic attraction part 16 and the second magnetic attraction part 25 are magnetically attracted. At this time, the first magnetic attraction part 16 and the second magnetic attraction part 25 fix the hook 24 relative to the guide rail 11, thus fixing the hook 24. Then, the building material rack 12 is raised and lowered, and the building material rack 12 drives the connector 13 to rise and fall. The raised and lowered connector 13 contacts the inclined surface of the hook 24. Under the push of the inclined surface, the connector 13 can rotate relative to the fixed block 15 and push the clamping plate 191 to rotate until the hook 24 passes through the hanging interface 1311 of the connector 13. At this time, the clamping plate 191 is reset under the elastic force of the first elastic part 192. The hook 24 and the connector 13 are hooked without manual intervention.

[0082] When the building is tall, a longer guide rail 11 needs to be formed by splicing to accommodate the height of the building. Therefore, in this embodiment, the guide rail 11 includes multiple guide segments 111 and multiple fasteners 112. When guide rails 11 of different heights need to be formed, multiple guide segments 111 are spliced ​​together. Between adjacent guide segments 111, the protrusions 113 of the guide segments 111 are inserted into the fixing holes of the adjacent guide segments 111, which realizes the positioning of the adjacent guide segments 111 and restricts their horizontal movement. The fasteners 112 are further provided to realize the detachable connection of two adjacent guide segments 111, so as to realize the relative fixation of two adjacent guide segments 111 and effectively prevent relative sliding between adjacent guide segments 111. By splicing multiple guide segments 111, a longer guide rail 11 can be formed.

[0083] Furthermore, in the above technical solution, the fastener 112 includes two connecting posts 1121, a bolt 1122, and a nut 1123. The two connecting posts 1121 are respectively connected to two adjacent guide sections 111. The two connecting posts 1121 are respectively provided with a first mounting hole and a second mounting hole. The second mounting hole is coaxially arranged with the first mounting hole. The threaded end of the bolt 1122 passes through the first mounting hole and the second mounting hole. The nut 1123 is threadedly connected to the threaded end of the bolt 1122.

[0084] Furthermore, in the above technical solution, the building material rack 12 includes a fixed box 121, a sliding frame 122, an end plate 123, and a second linear drive unit 124. There are two sliding frames 122 and two end plates 123, and multiple second linear drive units 124. The fixed box 121 has openings at the top and both ends. Two sliding frames 122 are slidably disposed at the two open ends of the fixed box 121. The sliding frames 122 are slidably connected to the fixed box 121. The end plates 123 correspond one-to-one with the sliding frames 122. The end plates 123 are disposed on the side of the sliding frame 122 away from the other sliding frame 122. One side of the end plate 123 is hinged to the sliding frame 122, and the other end is movably connected to the sliding frame 122. The fixed end of the second linear drive unit 124 is connected to the sliding frame 122, and the movable end is hinged to the fixed box 121. The fixed box 121 has a notch, and multiple fixing blocks 15 are located on both sides of the notch and connected to the fixed box 121.

[0085] The building material rack 12 also includes multiple sliding sleeves 125 and second rollers 126. The sliding sleeves 125 are arranged in a one-to-one correspondence with the guide rails 11. The sliding sleeves 125 are fitted on the guide section 111 and fixedly connected to the fixed box 121. The sliding sleeves 125 have a fixing opening at the position of the connecting column 1121. The multiple second rollers 126 are built into the sliding sleeves 125 and the second rollers 126 roll against the guide section 111.

[0086] Furthermore, in the above technical solution, the connector 13 includes a lifting block 131, a connecting rope 132, and a lifting ring 133. There are multiple connecting ropes 132 and lifting rings 133. The two sides of the lifting block 131 are slidably inserted into the fixing grooves of two fixing blocks 15. The lifting block 131 has a hanging interface 1311 along the direction of the notch. One end of the multiple connecting ropes 132 is connected to the lifting block 131. The lifting rings 133 are arranged in a one-to-one correspondence with the connecting ropes 132. The lifting rings 133 are threadedly connected to the building materials.

[0087] The guide rail 11 also includes multiple connecting rods 114, one end of which is connected to the guide section 111.

[0088] Furthermore, in the above technical solution, the lifting assembly 1 also includes a plurality of reinforcing members 17, which are distributed at guide intervals along the guide rail 11, and the reinforcing members 17 are connected to a plurality of guide segments 111.

[0089] The reinforcement component 17 includes a reinforcing beam 171 and a reinforcing block 172. The reinforcing block 172 corresponds one-to-one with the guide rail 11. One end of the reinforcing block 172 is connected to the guide section 111. The reinforcing block 172 is located on the side of the guide section 111 away from the fixed box 121. The other end of the reinforcing block 172 is connected to the reinforcing beam 171. The size of the reinforcing block 172 is smaller than the size of the fixing opening.

[0090] The drive unit 14 includes a first winch 141 and a first wire rope 142. The first winch 141 is fixed on the guide rail 11. One end of the first wire rope 142 is wound around the first winch 141, and the other end of the first wire rope 142 is connected to the building material rack 12.

[0091] When the building material rack 12 needs to be raised or lowered, the first winch 141 is started. The first winch 141 drives the first wire rope 142 to wind up, and the first wire rope 142 drives the building material rack 12 to rise or fall, so that the building material rack 12 moves to the preset height. When the building material rack 12 needs to be lowered, the first winch 141 is started. The first winch 141 drives the first wire rope 142 to unwind, and the building material rack 12 drives the first wire rope 142 to fall under the action of gravity.

[0092] The first winch 141 can be installed at the top of the guide rail 11. In this case, by starting the first winch 141, the first wire rope 142 can be directly wound and unwound, and the winding and unwinding of the first wire rope 142 can drive the building material rack 12 to rise and fall. Alternatively, the first winch 141 can be installed at the bottom of the guide rail 11. In this case, a first roller is installed at the top of the guide rail 11. The first wire rope 142 passes around the first roller and is connected to the building material rack 12. The first winch 141 can directly drive the first wire rope 142 to be wound and unwound, and the winding and unwinding of the first wire rope 142 can drive the building material rack 12 to rise and fall.

[0093] Furthermore, in the above technical solution, the lifting assembly 1 also includes a guide member 18, which includes a rotating frame 181, a first roller 182, and a first linear drive unit 183. The rotating frame 181 is rotatably connected to the guide rail 11, and the first roller 182 is rotatably connected to the rotating frame 181. The rotating frame 181 has a fixed end and a telescopic end. The fixed end of the rotating frame 181 is hinged to the guide rail 11, and the first linear drive unit 183 is used to drive the rotating frame 181 to rotate.

[0094] When the building material rack 12 moves to the preset height, the building materials need to be moved by the hook 24. In order to avoid the first roller 182 interfering with the lifting and moving of the building materials in the building material rack 12, the first linear drive unit 183 is activated. The first linear drive unit 183 drives the rotating frame 181 to rotate, and the rotating frame 181 drives the first roller 182 to rotate, so that the first roller 182 rotates to deviate from the sliding path of the building material rack 12, which can effectively prevent the first roller 182 from interfering with the movement of the building materials.

[0095] When it is necessary to raise or lower the building material rack 12, the first linear drive unit 183 is activated. The first linear drive unit 183 drives the rotating frame 181 to rotate, and the rotating frame 181 drives the first roller 182 to rotate, so that the first roller 182 rotates to the top of the building material rack 12. Then the first winch 141 is activated. The first winch 141 drives the first wire rope 142 to wind or unwind. After the first wire rope 142 passes around the first roller 182, it drives the first winch 141 to raise or lower.

[0096] The first roller 182 can deviate from the building material rack 12 under the drive of the first linear drive unit 183, so as to avoid the first roller 182 interfering with the lifting and lowering of the building materials. The first roller 182 can be moved to the top of the building material rack 12 by the drive of the first linear drive unit 183, so that the building material rack 12 bears the vertical traction force, and avoids the traction force being located on one side of the building material rack 12, so that the building material rack 12 will not apply too much load to the guide rail 11 when sliding, so that the guide rail 11 only plays the role of providing guidance for the building material rack 12, so that the building material rack 12 can slide smoothly relative to the guide rail 11, and reduce the wear of the guide rail 11.

[0097] Specifically, the principle of this invention is as follows: When it is necessary to lift or lower building materials, the building materials are placed in the receiving cavity of the building material rack 12. After being received, the connecting piece 13 is connected to the building materials and detachably connected to the building material rack 12. After being received, the driving component 14 is activated, and the driving component 14 guides the building material rack 12 to lift or lower along the guide rail 11. Since the building material rack 12 has stable guidance and support from the guide rail 11, the safety of lifting or lowering the building materials can be ensured, and the building materials can be lifted or lowered quickly. After the building materials are lifted or lowered to the preset location, the hook 24 and the connecting piece 13 can be detachably connected. Disassemble the connection and disconnect the connector 13 from the building material rack 12. Then, start the drive unit 14. The drive unit 14 controls the building material rack 12 to descend. The weight of the building material acts on the hook 24. Then, through the sliding carriage 23, the hook 24 and the building material are moved along the guide of the boom 22. The carriage 23 drives the hook 24 and the building material to rotate in the horizontal plane, so that the hook 24 moves the building material to the preset position. After the building material moves to the preset position, disconnect the connector 13 from the hook 24. Then, the building material is spliced ​​to construct the building by assembly.
