Description

Technical Field

[0001] The present application relates to the technical field of building construction, and in particular to a building construction mounting frame. Background Art

[0002] Housing construction refers to various types of housing buildings and their ancillary facilities, as well as the supporting wiring, pipelines, equipment installation projects and indoor and outdoor decoration projects. Housing construction often requires working on high-altitude construction scaffolding, which makes it inconvenient to transport building materials such as reinforcing bars and steel, so loading racks are often used to lift and transport building materials.

[0003] The Chinese patent with the authorization announcement number CN207063468U discloses a building construction carrier, including a platform, a lifting platform is vertically slidably connected to the side of the platform, and a connecting rope is commonly connected to the four corners of the lifting platform, and the connecting rope is connected to the rotating drum on the platform. When in use, the building materials are placed in the lifting platform, and then the lifting platform is driven up by rotating the rotating drum, so as to realize the lifting and transportation of the building materials.

[0004] With regard to the above-mentioned related technical solutions, after the building construction mounting frame has been used for a period of time and the lifting platform has been bearing a heavy load of building materials for a long time, the connecting rope may break accidentally. At this time, the lifting platform may fall directly to the ground, posing a serious safety hazard. Summary of the invention

[0005] Based on this, the present application provides a building construction mounting frame, which can reduce the direct fall of the lifting platform when the pull rope breaks accidentally, thereby reducing safety hazards.

[0006] The present application provides a building construction mounting frame adopting the following technical solution: A building construction carrier, comprising a carrier body, a lifting unit slidably arranged on the side of the carrier body, and a rope winding unit for driving the lifting unit to rise and fall; the lifting unit comprises a lifting base vertically slidably connected to the carrier body and a working platform laterally slidably connected to the lifting base, and the rope winding unit comprises a main load-bearing rope connected to the working platform, an auxiliary pull rope elastically connected to the lifting base, and a driving mechanism for driving the main load-bearing rope and the auxiliary pull rope to synchronously reel in / out; The carrier body is fixed with multiple safety supports, each of which is arranged at intervals along the height direction; a positioning member is fixed on the side of the working platform, and the positioning member is used to cooperate with the safety support to abut and limit the position when the lifting unit falls accidentally; The inner side surface of the lifting base close to the carrier body is set as the side foundation surface. When the rope winding unit drives the lifting unit to move up and down, the working platform is against the side foundation surface, and the positioning component is staggered with the safety support along the moving direction of the lifting unit; when the main load-bearing rope breaks accidentally, the working platform is against the lifting base due to the action of gravity and maintains a distance from the side foundation surface. At this time, the safety support is located on the moving path of the positioning component.

[0007] By adopting the above technical solution, the driving mechanism in the present application can force the main load-bearing rope and the auxiliary pull rope to be reeled or unreeled synchronously when in operation, so that the lifting base and the working platform can be lifted and lowered to lift and transport workers and building materials. During the lifting and lowering process of the lifting unit, the main load-bearing rope is in a tensioned state and plays a major load-bearing role, which is used to overcome the gravity of the lifting base and the working platform; the auxiliary pull rope can be in a slightly relaxed state, at which time the lifting base can naturally move downward under the action of its own gravity and keep the working platform against the side foundation surface, so that the positioning component can avoid the safety support to facilitate the smooth lifting and lowering of the lifting unit.

[0008] When the main load-bearing rope breaks unexpectedly, the lifting unit moves downward naturally, and the auxiliary pull rope can be in a tensioned state. The gravity load of the lifting unit is transferred to the auxiliary pull rope. Since the auxiliary pull rope is elastically connected to the lifting base, the descent speed of the lifting base can be slowed down. At this time, the descent speed of the working platform is greater than the descent speed of the lifting base, and it can move relative to the working platform and away from the side foundation surface, that is, it produces lateral movement. The positioning component can move to above the safety support and finally abut against the safety support to prevent the lifting unit from continuing to fall, which greatly improves the safety of construction operations and reduces safety hazards.

[0009] Optionally, a wedge-shaped seat is provided on the inner side of the lifting base, the side surface of the wedge-shaped seat is against the side base surface, and the distance from the upper surface of the wedge-shaped seat to the inner bottom surface of the lifting base gradually decreases from the side of the wedge-shaped seat close to the side base surface to the other side; a slide rail is installed on the upper surface of the wedge-shaped seat, and the side edge of the bottom of the working platform is provided with an inclined portion, and a slider adapted to the sliding of the slide rail is fixed to the inclined portion.

[0010] By adopting the above-mentioned technical solution, through the cooperation of the slider and the slide rail, when the driving mechanism drives the lifting unit up and down, the working platform can move along the top surface and side of the wedge-shaped seat until it is against the side foundation surface; when the main bearing rope breaks unexpectedly, the working platform can naturally slide down along the top surface of the wedge-shaped seat under the action of its own gravity, thereby automatically moving away from the side foundation surface, so as to facilitate the positioning component to enter above the safety support and cooperate with the safety support to abut against the limit.

[0011] Optionally, the inner bottom surface of the lifting base is paved with a flexible shock-absorbing pad.

[0012] By adopting the above-mentioned technical solution, when the working platform naturally moves downward and rests against the inner bottom surface of the lifting base, the setting of the flexible shock-absorbing pad can reduce the impact and vibration intensity between the working platform and the lifting base, thereby reducing the possibility of building materials placed on the working platform accidentally jumping out due to force, thereby reducing safety hazards.

[0013] Optionally, a plurality of material blocking seats are fixed to the side base surface of the lifting base, and the material blocking seats are movably arranged on the working platform and are always partially located on the inner side of the working platform.

[0014] By adopting the above-mentioned technical solution, when the driving mechanism drives the lifting unit to move up and down, the working platform moves toward the direction close to the side base surface, which can force the material blocking seat to move relatively toward the inside of the working platform, which is beneficial to protecting the building materials placed on the working platform and reducing the risk of building materials accidentally jumping out of the working platform and accidentally falling.

[0015] Optionally, the rope winding unit further comprises a rotating shaft, a first rotating drum and a second rotating drum, wherein the rotating shaft is rotatably mounted on the carrier body; the first rotating drum and the second rotating drum are respectively fixedly sleeved on the rotating shaft, the main load-bearing rope is wound around the first rotating drum, and one end of the main load-bearing rope is connected to the first rotating drum; the auxiliary pull rope is wound around the second rotating drum, and one end of the auxiliary pull rope is connected to the second rotating drum, and the other end is elastically connected to the lifting base through a spring hook; The driving mechanism includes a worm wheel, a worm and a driving motor. The worm wheel is fixed to one end of the rotating shaft; the driving motor is fixed to the carrier body, the worm is coaxially connected to the output end of the driving motor, and the worm and the worm wheel are meshed with each other for transmission.

[0016] By adopting the above-mentioned technical scheme, by controlling the operation of the driving motor, the transmission cooperation between the worm wheel and the worm can be used to rotate the rotating shaft, thereby driving the first rotating drum and the second rotating drum on the rotating shaft to rotate synchronously, thereby playing the role of lifting or lower lifting unit; and, since there is a self-locking function between the worm wheel and the worm, if the driving motor is accidentally powered off, the self-locking function can reduce the possibility of the lifting unit falling directly due to its own gravity, which is also beneficial to improving the safety of construction operations and reducing safety hazards.

[0017] Optionally, the carrier body has a main steel leg, which is detachably fixed with a fixing plate through a plug-in positioning structure, each safety support is fixed to the fixing plate, and the safety support is arranged to be inclined upward in a direction away from the fixing plate.

[0018] By adopting the above-mentioned technical solution, by setting up a fixing plate to fix each safety support, and the fixing plate being detachably fixed to the main steel leg of the carrier body through a plug-in positioning structure, it is possible to facilitate the rapid installation of each safety support; and by setting the safety support upwardly and tilted away from the fixing plate, the positioning component can remain stably against the safety support in the event of a fall, thereby ensuring construction safety.

[0019] Optionally, the plug-in positioning structure includes a plug-in column arranged on the fixed plate and a plug-in slot opened on the main steel foot column, wherein the main steel foot column is hollow inside, and the plug-in slot is connected to the inside of the main steel foot column; the size of the plug-in column is adapted to the size of the plug-in slot, and the bottom of the plug-in column is provided with a first slot for adapting to the wall thickness of the main steel foot column; The plug-in positioning structure also includes a positioning plate that is slidably connected to the main steel leg column. A second slot is provided on the top of the plug-in column, and the second slot is used to cooperate with the positioning plate for plug-in limiting. The positioning plate is movably plugged with a limiting piece, and a tension spring is provided between the limiting piece and the positioning plate. A limiting hole is provided on the side of the main steel leg column close to the positioning plate. When the positioning plate is plugged into the second slot, the tension spring forces the limiting piece to match and be inserted into the limiting hole.

[0020] By adopting the above-mentioned technical solution, by inserting the plug-in column into the plug-in slot of the main steel leg column, the main steel leg column can be clamped in the first clamping slot of the plug-in column, and then, by making the positioning plate match and be plugged into the second clamping slot of the plug-in column, the limit member can stay in a position opposite to the limit hole, and under the elastic force of the tension spring, the limit member can be matched and inserted in the limit hole, thereby realizing the stable positioning of the positioning plate, and then the plug-in column is matched and plugged and fixed in the plug-in slot.

[0021] Optionally, a return spring is provided between the positioning plate and the main steel foot column, and the return spring is used to force the positioning plate to be normally inserted into the second slot.

[0022] By adopting the above-mentioned technical solution, the setting of the return spring can always generate an elastic force acting on the positioning plate, so that after the plug-in column is inserted into the positioning hole, the positioning plate can be naturally inserted into the second slot, and it is beneficial for the limiting member to be naturally located at a position opposite to the limiting hole, which is beneficial to the stable plug-in fit between the limiting member and the limiting hole.

[0024] By adopting the above-mentioned technical solution, by setting up a walking mechanism to move along the extension direction of the guide rod, it is helpful to reduce the shaking of the lifting unit during the rising process; and by extending the end of the guide rod to above the carrier body, the driving mechanism drives the lifting unit to move upward so that the open side of the working platform can be finally tilted relative to the vertical direction, so that the operating personnel can take the building materials placed on the working platform.

[0025] Optionally, the walking mechanism includes a connecting seat fixed to the lifting base and a walking wheel rotatably connected to the connecting seat, and the walking wheel abuts against the main steel foot column; the connecting seat is provided with a through groove passing through both sides, the inner wall of the through groove is provided with an annular sleeve, and the guide rod is passed through the annular sleeve.

[0026] By adopting the above-mentioned technical solution, by allowing the guide rod to pass through the annular sleeve, the connecting seat can be moved along the extension direction of the guide rod, and when the connecting seat passes through the bending position of the guide rod, the annular sleeve can be deformed by force and avoid it, which is conducive to the connecting seat passing the bending position smoothly, thereby making the open side of the lifting unit finally inclined relative to the vertical direction.

[0027] In summary, the present application includes at least one of the following beneficial technical effects: 1. By setting the positioning member, when the main load-bearing rope breaks unexpectedly, the working platform can move away from the side foundation surface, so that the positioning member can move above the safety support and finally abut against the safety support to prevent the lifting unit from falling further, which greatly improves the safety of the construction work and reduces safety hazards; 2. By setting a wedge-shaped seat, when the main load-bearing rope breaks unexpectedly, the working platform can slide down naturally along the top surface of the wedge-shaped seat under the action of its own gravity, thereby automatically moving away from the side foundation surface, so as to facilitate the positioning component to enter the top of the safety support and cooperate with the safety support to abut against the limit position; 3. When the working platform moves downward naturally and rests against the inner bottom surface of the lifting base, the setting of the flexible shock-absorbing pad can reduce the impact and vibration intensity between the working platform and the lifting base, thereby reducing the possibility of building materials placed on the working platform accidentally jumping out due to force, reducing safety hazards.

[0030] The following is combined with Figure 1-7 This application is described in further detail.

[0031] The embodiment of the present application discloses a building construction mounting frame.

[0032] Reference Figure 1 A building construction carrier comprises a carrier body 1, a lifting unit 2 slidably arranged on the side of the carrier body 1, and a rope winding unit 3 for driving the lifting unit 2 to rise and fall; wherein, the carrier body 1 comprises a working platform 11 and four supporting steel legs 12 fixed to the bottom of the working platform 11, and the four supporting steel legs 12 are respectively arranged at the four corners of the working platform 11.

[0033] In this embodiment, the two supporting steel legs 12 close to the lifting unit 2 are set as the main steel legs 13, and a guide rod 14 is set on the side of each main steel leg 13. The cross-sectional shape of the guide rod 14 is circular. The bottom end of the guide rod 14 is welded and fixed to the main steel leg 13, and the top end of the guide rod 14 extends above the working platform 11.

[0034] The lifting unit 2 includes a lifting base 21 and a working platform 22, wherein the lifting base 21 is equipped with two sets of walking mechanisms 23, and the two sets of walking mechanisms 23 are correspondingly arranged on two guide rods 14, so that the walking mechanisms 23 can move along the extension direction of the guide rods 14, thereby enabling the lifting base 21 to be vertically slidably connected to the carrier body 1.

[0035] Reference Figure 2 The walking mechanism 23 includes a connecting seat 231 and a walking wheel 232. The connecting seat 231 is fixed to the side of the lifting base 21 close to the main steel leg 13; the connecting seat 231 is provided with a through groove, which passes through the upper and lower side surfaces of the connecting seat 231, and an annular sleeve 233 is bonded and fixed to the inner circumferential wall of the through groove, and the guide rod 14 can be inserted into the annular sleeve 233; the walking wheel 232 is rotatably installed on the side of the connecting seat 231 close to the main steel leg 13, and the walking wheel 232 can abut against the adjacent main steel leg 13.

[0036] Also refer to Figure 1 The annular gasket 233 in this embodiment is made of flexible materials such as silicone or rubber. When the lifting base 21 is lifted upward along the guide rod 14, the annular gasket 233 abuts against the guide rod 14, which can reduce the shaking of the lifting base 21; in addition, when the lifting base 21 passes through the bending position of the guide rod 14, the annular gasket 233 can be deformed by force and avoid it, which is conducive to the connection seat 231 to pass the bending position smoothly, and finally the open side of the lifting unit 2 is tilted relative to the vertical direction.

[0037] Reference Figure 3 In this embodiment, the inner side surface of the lifting base 21 close to the carrier body 1 is set as the side base surface 211, and the working platform 22 is located on the inner side of the lifting base 21 and is laterally slidably connected to the lifting base 21, so that the working platform 22 can move in the direction close to / away from the side base surface 211. Specifically, a wedge-shaped seat 212 is fixed to the inner bottom surface of the lifting base 21, and the side surface of the wedge-shaped seat 212 close to the carrier body 1 is pressed against the side base surface 211, and the distance between the upper surface of the wedge-shaped seat 212 and the inner bottom surface of the lifting base 21 gradually decreases from the side of the wedge-shaped seat 212 close to the side base surface 211 to the other side; a slide rail 213 is fixed to the upper surface of the wedge-shaped seat 212, and the extension direction of the slide rail 213 is facing the carrier body 1.

[0038] The bottom of the working platform 22 is provided with an inclined portion, and the lower surface of the inclined portion is parallel to the upper surface of the wedge block; a slider 221 is fixed to the bottom of the inclined portion, and the slider 221 can be slidably installed on the slide rail 213, so that the working platform 22 can slide freely along the upper surface of the wedge. The working platform 22 can be used to place building materials and can also be used to carry workers. It can be known that under normal conditions, the working platform 22 is affected by its own gravity and the gravity of the carried objects, and can naturally move downward and abut against the inner bottom surface of the lifting base 21. At this time, the working platform 22 can maintain a distance from the side foundation surface 211.

[0039] In addition, the inner bottom surface of the lifting base 21 is paved with a flexible shock-absorbing pad 24. The flexible shock-absorbing pad 24 can be made of a polyurethane foam pad, which can reduce the impact and vibration intensity between the working platform 22 and the lifting base 21, and reduce the possibility of building materials placed on the working platform 22 accidentally jumping out due to force.

[0040] A positioning member 25 is provided on the side of the work platform 22. The positioning member 25 includes an integrally formed connecting portion 251 and an abutting portion 252. One end of the connecting portion 251 away from the abutting portion 252 is fixedly connected to the side of the work platform 22, and a side base surface 211 of the lifting base 21 is provided with an avoidance groove for the connecting portion 251 to move through. Figure 2 It should be noted that there are two positioning members 25 , and the two positioning members 25 are symmetrically arranged on the side of the working platform 22 close to the carrier body 1 .

[0041] Reference Figure 4 The carrier body 1 is provided with a plurality of safety supports 15, which are used to cooperate with the positioning member 25 to abut against the limit position, and can play a supporting role when the lifting unit 2 falls unexpectedly, thereby reducing the occurrence of safety accidents. Specifically, a fixing plate 16 is detachably fixed on the side of the main steel leg 13 away from the guide rod 14, and each safety support 15 is fixed to the side of the fixing plate 16 away from the main steel leg 13, and all safety supports 15 are arranged at equal intervals in the height direction; in addition, each safety support 15 is arranged in a direction away from the fixing plate 16 and inclined upward.

[0042] A plug-in positioning structure is provided between the fixing plate 16 and the main steel leg 13, through which the fixing plate 16 and the main steel leg 13 can be quickly installed and removed; Figure 5The plug-in positioning structure includes a plug-in column 17 vertically fixed to the fixing plate 16 and a plug-in slot 131 opened in the main steel leg column 13. Each supporting steel leg column 12 is hollow inside, and the plug-in slot 131 opened in the main steel leg column 13 can be connected to the inside of the main steel leg column 13. The shape and size of the plug-in column 17 are the same as those of the plug-in slot 131, so that the plug-in column 17 can be matched and inserted in the plug-in slot 131.

[0043] Reference Figure 5 , Figure 6 A first slot 171 is provided at the bottom of the plug-in column 17, and the width of the first slot 171 is equal to the wall thickness of the main steel leg 13. When the plug-in column 17 is inserted into the plug-in slot 131, the plug-in column 17 can be clamped on the main steel leg 13 through the first slot 171, which plays a role in preliminary positioning. In addition, the plug-in positioning structure also includes a positioning plate 18 that is slidably connected to the main steel leg 13. The positioning plate 18 is located on the side of the main steel leg 13 away from the guide rod 14, and a reset spring 181 is provided between the positioning plate 18 and the column steel leg; a second slot 172 is provided on the top of the plug-in column 17, and the width of the second slot 172 is equal to the width of the positioning plate 18. When the plug-in column 17 is clamped in the main steel leg 13 through the first slot 171, the positioning plate 18 can be aligned with the second slot 172, and the elastic force generated by the reset spring 181 acting on the positioning plate 18 can force the positioning plate 18 to automatically clamp in the second slot 172.

[0044] In addition, the positioning plate 18 is provided with mounting holes 182 that pass through on both sides, and a stopper 19 is movably inserted in the mounting hole 182, and the outer diameter of the stopper 19 is equal to the inner diameter of the mounting hole 182; a stopper 191 is provided on the side of the stopper 19 away from the main steel leg 13, and the stopper 191 and the stopper 19 are integrally formed. A tension spring 192 is provided between the stopper 19 and the positioning plate 18, and one end of the tension spring 192 is hooked and fixed to the stopper 191, and the other end is hooked and fixed to the positioning plate 18; the tension spring 192 can always generate elastic force acting on the stopper 19, thereby forcing the stopper 19 to move in the direction close to the main steel leg 13.

[0045] A limiting hole 132 is provided on the side of the main steel foot column 13, and the inner diameter of the limiting hole 132 is equal to the outer diameter of the limiting member 19. When the positioning plate 18 is inserted into the second slot 172 under the elastic force of the reset spring 181, the limiting member 19 can be located opposite to the limiting hole 132. At this time, the limiting member 19 can be inserted into the limiting hole 132 under the elastic force of the tension spring 192, thereby achieving stable positioning of the plug-in column 17 and the fixing plate 16.

[0046] Reference Figure 7The rope winding unit 3 includes a main load-bearing rope 31, an auxiliary pull rope 32, a rotating shaft 33, a first rotating drum 34, a second rotating drum 35 and a driving mechanism; wherein a mounting support 111 is provided on the top of the working platform 11, and the rotating shaft 33 is rotatably mounted on the mounting support 111, so that the rotating shaft 33 is rotatably mounted on the carrier body 1. The driving mechanism includes a worm wheel 36, a worm 37 and a driving motor 38, wherein the worm wheel 36 is coaxially fixed to one end of the rotating shaft 33; the driving motor 38 is fixed to the top surface of the working platform 11, and the worm 37 is coaxially fixed to the output end of the driving motor 38, and the worm 37 and the worm wheel 36 are meshed with each other for transmission. When the driving motor 38 is in operation, the rotating shaft 33 can be driven to rotate through the transmission cooperation between the worm 37 and the worm wheel 36.

[0047] Also refer to Figure 1 The first rotating drum 34 and the second rotating drum 35 are respectively fixedly sleeved on the outer peripheral side of the rotating shaft 33; the main load-bearing rope 31 is wound around the first rotating drum 34, one end of the main load-bearing rope 31 is fixedly connected to the first rotating drum 34, and the other end is fixedly connected to the working platform 22. The auxiliary pull rope 32 is wound around the second rotating drum 35, one end of the auxiliary pull rope 32 is fixedly connected to the second rotating drum 35, and the other end is elastically connected to the lifting base 21 through the spring hook 321. When the driving motor 38 is in operation, the rotation of the rotating shaft 33 can drive the first rotating drum 34 and the second rotating drum 35 to rotate together, thereby causing the main load-bearing rope 31 and the auxiliary pull rope 32 to be reeled / unreeled synchronously.

[0048] It should be noted here that when the building construction carrying frame in this embodiment is in use, the main load-bearing rope 31 is in a tensioned state, which can play a major load-bearing role and is used to overcome the gravity of the lifting base 21 and the working platform 22; the auxiliary pull rope 32 is in a slightly relaxed state. When the drive motor 38 operates to drive the lifting unit 2 to move up and down, the lifting base 21 can naturally move downward under the action of its own gravity and keep the working platform 22 against the side foundation surface 211. At this time, the positioning member 25 can be staggered with the safety support 15 along the moving direction of the lifting unit 2, thereby avoiding the safety support 15 to facilitate the smooth lifting of the lifting unit 2.

[0049] When the main bearing rope 31 breaks accidentally, the working platform 22 can move downward naturally under the action of gravity and normally rest against the inner bottom wall of the lifting base 21, so that the positioning component 25 moves toward the main steel foot column 13; the safety support 15 can be located on the moving path of the positioning component 25, thereby preventing the lifting unit 2 from falling directly and reducing safety hazards.

[0050] In addition, back to Figure 3A plurality of material blocking seats 26 are fixed to the side base surface 211 of the lifting base 21. The material blocking seats 26 are movably arranged on the working platform 22 and are always partially located inside the working platform 22. The bottom of the material blocking seats 26 is arranged in an arc shape. The arrangement of the material blocking seats 26 can protect the building materials placed on the working platform 22, reducing the risk of the building materials accidentally jumping out of the working platform 22 and accidentally falling. When the driving motor 38 operates and lifts the lifting unit 2 above the working platform 11, the open side of the lifting unit 2 is inclined relative to the vertical direction. At this time, the arrangement of the material blocking seats 26 can reduce the risk of the building materials rolling down, further improving safety.

[0051] The implementation principle of a building construction mounting frame in the embodiment of the present application is as follows: When the building construction mounting frame of the present application is in use, the driving motor 38 is activated to drive the lifting unit 2 to move up and down. At this time, the main load-bearing rope 31 is in a tensioned state and plays a major load-bearing role, used to overcome the gravity of the lifting base 21 and the working platform 22.

[0052] When the main load-bearing rope 31 breaks unexpectedly, the lifting unit 2 moves downward naturally, and the auxiliary pull rope 32 can be in a tensioned state. The gravity load of the lifting unit 2 is transferred to the auxiliary pull rope 32. Since the auxiliary pull rope 32 and the lifting base 21 are elastically connected, the descending speed of the lifting base 21 can be slowed down; as the lifting unit 2 descends, the elastic force between the auxiliary pull rope 32 and the lifting base 21 gradually reaches the limit, and due to the self-locking function of the worm gear 36 and worm 37, the descending speed of the lifting base 21 is gradually less than the descending speed of the working platform 22. The working platform 22 can move relative to the working platform 22 and in a direction away from the side foundation surface 211, that is, it produces lateral movement, and the positioning member 25 can move above the safety support 15 and finally abut against the safety support 15 to prevent the lifting unit 2 from continuing to fall, which greatly improves the safety of construction operations and reduces safety hazards.

[0053] The above are preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
