Description

Technical Field

[0001] The invention relates to an electric building construction machine, belonging to the technical field of building construction. Background Art

[0002] Due to the rapid advancement of urbanization, the available land resources in cities have become scarce, and high-rise buildings and high-density residential communities have emerged. High-rise buildings have the advantages of saving land resources, outstanding earthquake resistance, complete supporting facilities, accommodating many residents, and good ventilation and lighting. The emergence of high-rise buildings conforms to the law of urban development and is the development trend of future urban buildings.

[0003] At present, traditional high-rise and super-high-rise buildings are constructed using hydraulic building machines. There are too many hydraulic lifting points, and the difficulty of hydraulic synchronous control increases with the increase in the number of hydraulic cylinders, making it difficult to control the synchronization of the overall hydraulic lifting points. In order to solve this problem, the usual practice is to design the overall rigidity of the building machine to be particularly large, thereby reducing the lifting points of the building machine.

[0004] However, in the actual construction process, with the reduction of hydraulic lifting points, the building structure at the lifting points of the existing hydraulic lifting building construction machine needs to bear a large load during the lifting process of the building construction machine. It is necessary to wait until the concrete structure at the lifting point has a certain strength before it can be lifted, which greatly slows down the construction progress, reduces the construction efficiency, and is not conducive to achieving rapid construction.

[0005] A hydraulic integral climbing system for a building construction machine disclosed in a Chinese utility model patent with publication number CN212249119U includes: a climbing guide rail, the climbing guide rail includes a front end plate and two side plates, the two ends of the front end plate have limit sections formed by protruding from the two side plates, there are several climbing guide rails, and the upper end of the climbing guide rail is fixedly connected to the working platform; a hanging shoe for fixed installation on the wall, there are several hanging shoes, each climbing guide rail is connected to the wall through at least two hanging shoes, and the hanging shoe includes a base, and the base has a front limit part, a rear limit part, a left limit part, and a right limit part. The overall system is through the hanging shoe attached to the building structure. Fixed attachment climbing guide rail system.

[0006] The above reference example controls the reciprocating motion of each cylinder through the hydraulic intelligent energy control system to achieve the synchronous lifting motion of the climbing guide rail, thereby achieving the purpose of climbing the entire building construction machine. However, in order to achieve the synchronous control of multiple hydraulic cylinders to realize the lifting of the building construction machine, it is necessary to reduce the lifting points, which makes the building body bear great pressure, which is not only easy to be damaged, but also seriously slows down the construction progress and reduces the construction efficiency. Therefore, improvement is urgently needed. Summary of the invention

[0007] In order to overcome the shortcomings of existing hydraulic lifting building machines, such as high load pressure on the building, slowing down the construction progress, and reducing construction efficiency, the present invention designs an electric building machine, which can effectively ensure the synchronization of lifting while meeting the requirements of multi-point lifting. It not only has a small load pressure on the building, but also has an anti-fall function to ensure safety.

[0008] In order to achieve the above object, the present invention adopts the following technical solution:

[0009] An electric building construction machine includes a Bailey frame and a plurality of support units arranged at the bottom end of the Bailey frame, each support unit is driven to lift upward by an electric climbing unit; the electric climbing unit includes an attachment unit and a lifting mechanism, the attachment unit is vertically arranged and fixedly connected to the wall, the support unit is vertically slidably connected to the attachment unit, the lifting mechanism is fixed on the support unit and an external drive motor drives the support unit to lift vertically.

[0010] Furthermore, the lifting mechanism comprises a worm gear screw lifter, the output end of the worm gear screw lifter is vertically upward and is transmission-connected with a transmission screw, and the free end of the transmission screw is connected to the attachment unit through a ball pair assembly.

[0011] Furthermore, the attachment unit includes a plurality of attachment supports fixed on the building body at intervals from top to bottom and a plurality of anti-fall blocks fixed on one side of the support unit close to the wall at intervals from top to bottom. One side of the attachment support is fixedly connected to the wall, and the other side is connected to the support unit for vertical sliding connection. An anti-fall stop pin is connected to the attachment support for horizontal sliding connection. When the anti-fall stop block pushes the anti-fall stop pin from bottom to top, the anti-fall stop pin moves away from the support unit. When the anti-fall stop block leaves the anti-fall stop pin, the anti-fall stop pin is set close to the support unit under the action of the reset assembly.

[0012] Furthermore, the reset assembly includes a pair of fixed blocks fixed on the attachment support, and guide rods are fixedly inserted on the two fixed blocks. The ends of the two guide rods slide through the two ends of the anti-fall stop pin respectively, and a return spring mounted on the guide rod is also fixedly connected between the fixed block and the anti-fall stop pin.

[0013] Furthermore, a guiding inclined surface is arranged at the top of the anti-falling stop block, and an anti-falling groove cooperating with the anti-falling stop pin to play an anti-falling role is arranged at the bottom of the anti-falling stop block.

[0014] Furthermore, the ball sub-assembly includes a hemispherical sub-assembly, a hemispherical body and a limit nut. The hemispherical sub-assembly is fixed to the top of the attachment support. The hemispherical sub-assembly is provided with a concave spherical groove that matches the hemispherical body. The hemispherical body is placed in the spherical groove. The transmission screw moves in sequence through the two connecting splints, the hemispherical sub-assembly and the hemispherical body, and then is threadedly connected to the limit nut.

[0015] Furthermore, a plurality of scaffolding boards are arranged between each supporting unit, the scaffolding boards are connected to the Bailey frame through a plurality of scaffolding uprights, and a sliding connection assembly is arranged at the connection between the scaffolding uprights and the Bailey frame.

[0016] Furthermore, the sliding assembly includes an I-beam, a sliding member and at least two connecting members, the lower end of the sliding member is used to install the bracket upright, the upper end of the sliding member is sleeved on the lower flange plate of the I-beam, the upper flange plate of the I-beam is sleeved on the connecting member, and each connecting member can be detachably connected to the Bailey frame; the upper end of the sliding member is provided with a U-shaped slide groove for accommodating the lower flange plate of the I-beam, and pulleys are rotatably installed on both inner side walls of the U-shaped slide groove, and the pulleys can roll along the length direction of the lower flange plate of the I-beam.

[0017] Furthermore, the connecting member includes a first mounting block and a second mounting block, the first mounting block is located above the second mounting block, a T-shaped slot is provided at the bottom of the second mounting block, the second mounting block is sleeved on the upper flange plate of the I-beam through the T-shaped slot, the first mounting block and the second mounting block are connected by connecting bolts and are fixed to the suspension beam of the Bailey frame passing through the two.

[0018] Furthermore, it also includes a material placing machine, which is lifted upward by an electric climbing unit.

[0019] Compared with the prior art, the present invention has the following characteristics and beneficial effects:

[0020] 1. The present invention, through the provision of multiple support units and electric climbing units matched with each support unit, drives the lifting mechanism to climb upward through multiple driving motors, thereby driving the entire building construction machine to climb upward. Compared with traditional hydraulic lifting, the present invention can easily realize multi-point synchronous control lifting without reducing the support points, and the provision of multiple support units effectively increases the load transfer points, reduces the load that each support point needs to bear, greatly improves the safety of the building construction machine during the lifting process, and can also reduce the amount of steel used in the building construction machine platform, realize lightweight design, and thus there is no need to wait for the concrete to solidify before lifting the building construction machine upward, which is conducive to improving work efficiency.

[0021] 2. The present invention arranges the ball sub-assembly. When the transmission screw is rotated under force, the hemisphere slides in the spherical groove. The force between the hemisphere sub-assembly and the hemisphere rotates with the corresponding angle of the transmission screw, so that the transmission screw always remains in a vertical state, ensuring the stability and synchronization of the support unit during the lifting process, preventing the Bailey frame from tilting, and ensuring smooth construction.

[0022] 3. The present invention arranges an attached support and an anti-fall block. Under normal circumstances, the return spring keeps the anti-fall stop pin under the anti-fall block. When the building machine moves downward as a whole, the anti-fall stop pin can just enter the anti-fall slot of the anti-fall block, thereby supporting the building machine as a whole. When the building machine moves upward as a whole, the guide slope abuts the anti-fall stop pin, causing the anti-fall stop pin to move to the side away from the supporting unit, thereby allowing the building machine as a whole to move upward smoothly. After the movement is completed, the anti-fall stop pin will return to its original position under the elastic force of the return spring, and continue to play the function of supporting and preventing falling, thereby further ensuring the safety during the lifting process.

[0023] 4. Through the setting of the sliding assembly, the present invention allows the bracket uprights to slide a certain distance along the direction of the steel flange plate of the I-beam, so that the distance between the bracket scaffolding board and the main structure after the main structure of the building is retracted as the height increases can be adjusted and reduced, thereby improving the safety performance of the bracket construction. The I-beam is connected to the suspension beam of the Bailey frame by two connecting parts. Since the upper flange plate of the I-beam is inserted into the T-slots of the two connecting parts, the distance of the I-beam relative to the building can be adjusted, and on this basis, the position of the sliding part on the I-beam is adjusted, thereby increasing the sliding space of the bracket uprights in a limited space.

[0024] 5. The present invention lifts the concrete placing boom upwards through a separate electric climbing unit. During the overall lifting stage of the building construction machine, the concrete placing boom is not connected to the supporting units, thereby reducing the load on the overall structure and ensuring that the structural strength between the supporting units will not be damaged. When the concrete placing boom is needed for construction, the concrete placing boom is lifted into place separately and then connected to the Bailey frame, so that the load of the concrete placing boom in the construction condition is unloaded to the Bailey frame. The load of the concrete placing boom in the construction condition is relatively small, and the load is then transferred to the Bailey frame, which effectively ensures safety while improving construction efficiency.

DETAILED DESCRIPTION

[0032] The present invention is described in more detail below with reference to the embodiments.

[0033] Embodiment 1

[0034] like Figures 1 to 4 As shown, an electric building construction machine includes a Bailey frame 2 and a plurality of support units 1 arranged at the bottom end of the Bailey frame 2, and each support unit 1 is driven to lift upward by an electric climbing unit; the electric climbing unit includes an attachment unit and a lifting mechanism, the attachment unit is vertically arranged and fixedly connected to the wall, the support unit 1 is vertically slidably connected to the attachment unit, the lifting mechanism is fixed on the support unit 1 and an external drive motor drives the support unit 1 to lift vertically.

[0035] From the above description, it can be seen that the beneficial effect of the present invention lies in that, through the setting of multiple support units 1 and electric climbing units compatible with each support unit 1, multiple drive motors are used to drive the lifting mechanism to climb upward, thereby driving the entire building construction machine to climb upward. Compared with traditional hydraulic lifting, the present invention can easily realize multi-point synchronous control lifting without reducing the support points, and the setting of multiple support units 1 effectively increases the load transfer points, reduces the load that each support point needs to bear, greatly improves the safety of the building construction machine during the lifting process, and can also reduce the amount of steel used in the building construction machine platform, realize lightweight design, and thus there is no need to wait for the concrete to solidify before lifting the building construction machine upward, which is conducive to improving work efficiency.

[0036] Furthermore, the lifting mechanism includes a worm gear screw lift 4, the output end of which is vertically upward and is transmission-connected to a transmission screw 401, and the free end of the transmission screw 401 is connected to the attachment unit through a ball pair assembly 7.

[0037] From the above description, it can be seen that the ball pair assembly 7 is used to offset the micro-deformation of the transmission screw 401, so that the transmission screw 401 always remains in a straight state. The selection of the worm gear screw lift 4 is low-cost and suitable for popularization and use. When lifting is required, the input shaft 402 of the worm gear screw lift 4 is driven to rotate by the motor, so that the worm gear screw lift 4 moves upward under the guidance of the transmission screw 401, and then drives the support unit 1 to lift upward. By setting up multiple worm gear screw lifts 4 and controlling them through the upper computer, the synchronous rising of multiple support units 1 can be achieved.

[0038] Furthermore, the attachment unit includes a plurality of attachment supports 6 fixed on the building body at intervals from top to bottom and a plurality of anti-fall blocks 105 fixed on the side of the support unit 1 close to the wall at intervals from top to bottom. One side of the attachment support 6 is fixedly connected to the wall, and the other side is connected to the support unit 1 for vertical sliding. An anti-fall stop pin 607 is laterally slidably connected to the attachment support 6. When the anti-fall stop block 105 pushes the anti-fall stop pin 607 from bottom to top, the anti-fall stop pin 607 moves away from the support unit 1. When the anti-fall stop block 105 leaves the anti-fall stop pin 607, the anti-fall stop pin 607 is set close to the support unit 1 under the action of the reset component.

[0039] In this embodiment, the attachment support 6 includes a fixed seat 601 and a pair of connecting clamps 602. One side of the fixed seat 601 is fixedly connected to the wall, and the other side is vertically fixedly connected to the two connecting clamps 602. The two connecting clamps 602 are spaced apart and arranged on both sides of the anti-fall block 105, and the free ends of the two connecting clamps 602 are respectively slidably engaged with the two sides of the support unit 1. An anti-fall stop pin 607 is transversely slidably connected between the two connecting clamps 602. Transverse guide grooves 603 are opened on the sides of the two connecting clamps 602. The transverse guide grooves 603 are horizontally arranged, and the two ends of the anti-fall stop pin 607 are respectively slidably engaged in the two transverse guide grooves 603.

[0040] From the above description, it can be seen that during the upward lifting of the support unit 1, the anti-fall block 105 will continuously cycle and abut against and leave the anti-fall stop pin 607. Through the setting of the reset component, the anti-fall stop pin 607 can return to its position and continue to abut against the anti-fall block 105, thereby effectively preventing the support unit 1 from falling and ensuring safety during the lifting process.

[0041] Furthermore, the reset assembly includes a pair of fixed blocks 604 fixed on the attachment support 6, and guide rods 605 are fixedly inserted on the two fixed blocks 604. The ends of the two guide rods 605 slide through the two ends of the anti-fall stop pin 607 respectively, and a return spring 606 mounted on the guide rod 605 is also fixedly connected between the fixed block 604 and the anti-fall stop pin 607.

[0042] In this embodiment, the reset assembly includes a fixed block 604 fixed to the outside of the two connecting clamps 602, and the fixed block 604 is arranged at the end of the transverse guide groove 603 away from the support unit 1, and a guide rod 605 is fixedly inserted on the fixed block 604, and the end of the guide rod 605 slides through the anti-fall stop pin 607, and a return spring 606 mounted on the guide rod 605 is also fixedly connected between the fixed block 604 and the anti-fall stop pin 607.

[0043] Furthermore, a guiding inclined surface 1052 is arranged at the top of the anti-falling stopper 105, and an anti-falling slot 1051 which cooperates with the anti-falling stopper pin 607 to prevent falling is arranged at the bottom of the anti-falling stopper 105.

[0044] From the above description, it can be seen that under normal conditions, the return spring 606 keeps the anti-fall stop pin 607 below the anti-fall block 105. When the building machine moves downward as a whole, the anti-fall stop pin 607 can just enter the anti-fall slot 1051 of the anti-fall block 105, thereby supporting the building machine as a whole. When the building machine moves upward as a whole, the guide slope 1052 abuts against the anti-fall stop pin 607, causing the anti-fall stop pin 607 to move to the side away from the support unit 1, thereby allowing the building machine as a whole to move upward smoothly. After the movement is completed, the anti-fall stop pin 607 will return to its original position under the elastic force of the return spring 606, and continue to play the role of supporting and preventing falling.

[0045] Embodiment 2

[0046] An electric building construction machine, based on the above-mentioned embodiment 1, further defines the overall mechanical structure and connection relationship of the ball pair assembly 7 as follows:

[0047] like Figure 4 As shown, the ball sub-assembly 7 includes a hemispherical sub-assembly 708, a hemispherical body 701 and a limiting nut 702. The hemispherical sub-assembly 708 is fixed to the top of the attachment support 6. The hemispherical sub-assembly 708 is provided with a concave spherical groove adapted to the hemispherical body 701. The hemispherical body 701 is placed in the spherical groove. The transmission screw 401 moves in sequence through the two connecting splints 602, the hemispherical sub-assembly 708 and the hemispherical body 701, and then is threadedly connected to the limiting nut 702.

[0048] From the above description, it can be seen that when the transmission screw 401 is rotated by force, the hemisphere 701 slides in the spherical groove, and the force between the hemisphere sub-assembly 708 and the hemisphere 701 rotates the corresponding angle as the transmission screw 401 rotates, so that the transmission screw 401 remains straight.

[0049] Embodiment 3

[0050] An electric building construction machine, based on the above-mentioned embodiment 1 or embodiment 2, further defines the overall mechanical structure and connection relationship of the building construction machine as follows:

[0051] like Figure 1 , Figure 5 and Figure 6 As shown, a plurality of hanging scaffolding boards 3 are arranged between each supporting unit 1 , and the hanging scaffolding boards 3 are connected to the Bailey frame 2 through a plurality of hanging frame uprights 804 , and a sliding connection assembly 8 is arranged at the connection between the hanging frame uprights 804 and the Bailey frame 2 .

[0052] It can be seen from the above description that the hanging scaffolding board 3 serves as an additional working platform, which improves the convenience of the operation and can be lifted together with the supporting unit 1, which is convenient and practical.

[0053] Furthermore, the sliding assembly 8 includes an I-beam 801, a sliding member 802 and two connecting members. The I-beam 801 is arranged toward the wall. The lower end of the sliding member 802 is used to install the bracket upright 804. The upper end of the sliding member 802 is sleeved on the lower flange plate of the I-beam 801. The upper flange plate of the I-beam 801 is sleeved on the connecting member. Each connecting member can be detachably connected to the Bailey frame 2; the upper end of the sliding member 802 is provided with a U-shaped slide groove for accommodating the lower flange plate of the I-beam 801, and pulleys 805 are rotatably installed on both inner side walls of the U-shaped slide groove, and the pulleys 805 can roll along the length direction of the lower flange plate of the I-beam 801.

[0054] From the above description, it can be seen that the I-beam 801 is set towards the building, and the bracket uprights 804 can slide a certain distance along the steel flange plate direction of the I-beam 801, so that the distance between the bracket scaffolding board 3 and the main structure after the main structure of the building is retracted as the height increases can be adjusted and reduced, thereby improving the safety performance of the bracket construction.

[0055] Furthermore, the connecting member includes a first mounting block 807 and a second mounting block 808, the first mounting block 807 is located above the second mounting block 808, a T-shaped slot is provided at the bottom of the second mounting block 808, the second mounting block 808 is sleeved on the upper flange plate of the I-beam 801 through the T-shaped slot, the first mounting block 807 and the second mounting block 808 are connected by connecting bolts 806 and are fixed to the suspension beam 803 of the Bailey frame 2 inserted therebetween.

[0056] From the above description, it can be seen that the I-beam 801 is connected to the suspension beam 803 of the Bailey frame 2 by two connecting parts. Since the upper flange plate of the I-beam 801 is inserted into the T-slots of the two connecting parts, the distance of the I-beam 801 relative to the building can be adjusted, and the position of the sliding member 802 on the I-beam 801 can be adjusted on this basis, thereby increasing the sliding space of the bracket upright 804 in a limited space.

[0057] Embodiment 4

[0058] An electric building construction machine, based on the above-mentioned embodiment 1, embodiment 2 or embodiment 3, the overall mechanical structure and connection relationship of the building construction machine are further defined as follows:

[0059] like Figure 6 As shown, the material placing machine 10 is also included, and the material placing machine 10 is lifted upward by an electric climbing unit.

[0060] From the above description, it can be seen that the placing crane 10 is lifted upward by a separate electric climbing unit. During the overall lifting stage of the building construction machine, the placing crane 10 is not connected to the supporting unit 1, which reduces the load on the overall structure and ensures that the structural strength between the supporting units 1 will not be damaged. When the placing crane 10 is needed for construction, the placing crane 10 is lifted into place separately, and then connected to the Bailey frame 2, so that the load of the placing crane 10 in the construction condition is unloaded to the Bailey frame 2. The load of the placing crane 10 in the construction condition is relatively small, and the load is then transferred to the Bailey frame 2, which effectively ensures safety while improving construction efficiency.

[0061] The working principle of the present invention is as follows: through the arrangement of multiple support units 1 and electric climbing units matched with each support unit 1, multiple driving motors are used to drive the lifting mechanism to climb upward, thereby driving the building construction machine as a whole to climb upward. Compared with traditional hydraulic lifting, the present invention can easily realize multi-point synchronous control lifting without reducing the support points, and the arrangement of multiple support units 1 effectively increases the load transfer points, reduces the load that each support point needs to bear, greatly improves the safety of the building construction machine during the lifting process, and can also reduce the amount of steel used in the platform of the building construction machine, realize lightweight design, and thus there is no need to wait for the concrete to solidify. Lifting the building machine upward after the soil solidifies is beneficial to improving work efficiency. The placing crane 10 is lifted upward by a separate electric climbing unit. During the overall lifting stage of the building machine, the placing crane 10 is not connected to the supporting unit 1, which reduces the load on the overall structure and ensures that the structural strength between the supporting units 1 will not be damaged. When the placing crane 10 is needed for construction, the placing crane 10 is lifted into place separately, and then connected to the Bailey frame 2, so that the load of the placing crane 10 in the construction condition is unloaded to the Bailey frame 2. The load of the placing crane 10 in the construction condition is relatively small, and the load is then transferred to the Bailey frame 2, which effectively ensures safety while also improving construction efficiency.
