Description

A special installation machine for steel structure building construction and its usage method Technical Field

[0001] This invention relates to a special installation machine for steel structure building construction and its usage method, belonging to the field of steel structure building construction technology. Background Technology

[0002] With the development of prefabricated buildings, more and more buildings are adopting this construction method with short construction cycles and low construction costs. However, it has been found during the construction process that because prefabricated buildings involve a large number of parts and modules, tower cranes are required to carry out frequent hoisting operations in the construction of high-rise buildings. Due to the influence of the construction work surface, it is difficult for multiple tower cranes to work at the same time, which greatly limits the construction progress. Summary of the Invention

[0003] This invention overcomes the shortcomings of existing technologies and provides a special installation machine for steel structure construction and its usage method. Multiple cranes can be arranged on one construction work surface, and the cranes are gradually lifted to the work surface. The climbing is fast and simple, which greatly improves the construction progress and reduces the construction cost.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows: a special installation machine for steel structure building construction, including a climbing frame unit, a support frame and a truss crane. The climbing frame unit is fixedly installed on different steel structure columns and serves as the support part of the support frame. The support frame is fixedly installed on the top of the climbing frame unit. The truss crane is fixedly installed on the support frame and has both rotation and lifting functions.

[0005] The climbing frame unit has the following structure: it includes four telescopic columns, a first climbing claw, a second climbing claw, and two connecting columns. The four telescopic columns are arranged vertically in a rectangle. The tops of the cylinders of two telescopic columns on the same side are connected and fixed together by connecting columns. The support frame is located between the two connecting columns and is fixed together with the connecting columns. The first climbing claw is fixedly installed at the bottom of the cylinder of each telescopic column, and the second climbing claw is installed on the telescopic rod at the lower end of the telescopic column. The first and second climbing claws can be fixedly engaged with the steel structure columns or alternately released from the steel structure columns. The telescopic columns are raised by alternating climbing with the first and second climbing claws.

[0006] The first and second climbing claws have the same structure. The first climbing claw has the following structure: it includes a claw mounting frame, claw head, slider, screw support seat, claw head screw, coupling, claw head motor, rotary motor and gear set. One end of the claw mounting frame is fixedly mounted on the telescopic column, and the other end of the claw mounting frame is movably provided with two claw heads. The two claw heads can grip the steel structure column or release from the steel structure column under power drive. Specifically, the tail of each claw head is fixedly provided with a slider, and each slider is correspondingly mounted on the claw head screw. The claw head screw is fixedly mounted on the screw support seat fixed on the claw mounting frame. The ends of the two claw head screws are poweredly connected to the claw head motor through the coupling. The claw head motor drives the two claw heads to realize the opening and closing action.

[0007] A gear set is fixedly installed on the top of the gripper mounting frame. The gear set is powered by a rotating motor fixed on the telescopic column. The rotating motor drives the gripper mounting frame to rotate around the telescopic column to perform action avoidance.

[0008] The telescopic column has a climbing screw installed inside its cylinder. The telescopic rod at the lower end of the telescopic column is movably mounted on the climbing screw. The top of the climbing screw is powered by a climbing motor fixed to the top of the telescopic column cylinder. The climbing motor drives the telescopic rod of the telescopic column to extend and retract, thereby causing the second climbing claw fixed to the telescopic rod to perform a corresponding lifting and lowering action.

[0009] The gripping part of the claw head matches the outer contour of the steel structure column, ensuring that the claw head can firmly grip the steel structure column.

[0010] The connecting component between the support frame and the connecting column is a telescopic structure.

[0011] The connecting column is a telescopic structure.

[0012] A support cylinder is fixedly installed on the upper part of the telescopic column, and the body of the climbing motor is fixed on the support cylinder.

[0013] The power head of the claw motor splits the power into two parts through a gear assembly or a turbine assembly and then connects them to the corresponding couplings.

[0014] The present invention discloses a method for using a special installation machine for steel structure building construction, which is implemented according to the following steps:

[0015] The first step is to assemble and install the machine;

[0016] After the first layer of steel structure columns are fixed, the four climbing frame units are fixed to the corresponding steel structure columns by their respective first and second climbing claws. Then, the connecting columns and support frames are assembled in sequence, and the truss is hoisted onto the support frame and fixed.

[0017] The second step is to complete the construction of the steel structure building on the floor where the installation machine is located and to build the steel structure building on the next floor.

[0018] Control the truss crane to perform the corresponding lifting operations;

[0019] The third step is for the truss crane to begin its climbing motion;

[0020] The first climbing claw releases the steel structure column, and then the telescopic rod of the telescopic column is extended by the climbing motor. Since the second climbing claw is fixed to the telescopic rod, the cylinder of the telescopic column is lifted, thereby driving the truss crane to rise.

[0021] If the climbing height is insufficient, continue to control the claw of the second climbing claw to release the steel structure column, and then drive the telescopic rod of the telescopic column to shorten through the climbing motor. After raising the second climbing claw, control the second climbing claw to grip the steel structure column, and then repeat the above lifting action of the truss crane. Depending on the actual situation, the above lifting action of the truss crane can be repeated until the appropriate height is reached.

[0022] The fourth step is for the installation machine to climb to the next floor;

[0023] The system controls the first climbing claw to release the steel structure column, and then controls the rotation motor to drive the first climbing claw's gripper mounting frame to rotate around its own telescopic column to avoid the upper crossbeam; then the climbing motor drives the telescopic column's telescopic rod to extend. Since the second climbing claw is fixed to the telescopic rod, the telescopic column's cylinder is lifted, causing the first climbing claw, which is fixed to the telescopic column's cylinder, to cross the crossbeam and reach the upper level. Then, the system controls the first climbing claw's claw to grip the upper level's structural column.

[0024] Continue to control the claw of the second climbing claw to release the steel structure column, then control the rotation motor to drive the gripper mounting frame of the second climbing claw to rotate around its own telescopic column to avoid the upper crossbeam; then drive the telescopic rod of the telescopic column to shorten by the climbing motor, lift the second climbing claw and cross the crossbeam to reach the upper floor, then control the second climbing claw to grip the steel structure column of the upper floor.

[0025] Fifth, repeat steps three and four until the steel structure construction is completed;

[0026] Step 6: Demolition;

[0027] The truss can be lifted directly from above the steel structure building by a crane, and the climbing frame unit can be connected to the support frame to descend to the first floor by reverse operation; or it can be lifted directly from above the steel structure building by a crane.

[0028] The climbing motor and rotating motor are both executed automatically through a predetermined program or manually controlled.

[0029] Compared with the prior art, the beneficial effects of this invention are as follows: This invention utilizes the characteristics of steel structure columns in prefabricated buildings, and controls the self-climbing structure to automatically climb along the steel structure columns, gradually raising the working surface of the truss crane. During the lifting process, it is not affected by the crossbeam, and the climbing action is simple and efficient. There is no need for a special tower crane operator to perform high-altitude operations. Multiple truss cranes can be deployed simultaneously on one construction working surface, which greatly improves the construction progress and reduces the construction cost.

[0037] The present invention will be further described below with reference to specific embodiments.

[0038] As shown in Figure 1, the present invention discloses a special installation machine for steel structure building construction, comprising a climbing frame unit 1, a support frame 2, and a truss crane 3. The climbing frame unit 1 is fixedly installed on different steel structure columns 4 and serves as the support part of the support frame 2. The support frame 2 is fixedly installed on the top of the climbing frame unit 1, and the truss crane 3 is fixedly installed on the support frame 2. The truss crane 3 has both rotation and lifting functions; wherein, the truss crane 3 is an existing unmanned remote control structure.

[0039] The structure of the climbing frame unit 1 includes four telescopic columns 11, a first climbing claw 12, a second climbing claw 13, and two connecting columns 14. The four telescopic columns 11 are arranged vertically in a rectangle. The tops of the cylinders of two telescopic columns 11 on the same side are connected and fixed together by the connecting columns 14. The support frame 2 is located between the two connecting columns 14 and is fixed together with the connecting columns 14. The first climbing claw 12 is fixedly installed at the bottom of the cylinder of the telescopic column 11, and the second climbing claw 13 is installed on the telescopic rod at the lower end of the telescopic column 11. The first climbing claw 12 and the second climbing claw 13 can be fixedly engaged with the steel structure column 4 or alternately released from the steel structure column 4. The telescopic column 11 is raised by alternating climbing of the first climbing claw 12 and the second climbing claw 13.

[0040] The first climbing claw 12 and the second climbing claw 13 have the same structure. The structure of the first climbing claw 12 includes a claw mounting frame 121, a claw head 122 slider 123, a lead screw support seat 124, a claw head lead screw 125, a coupling 126, a claw head motor 127, a rotary motor 128, and a gear set 129. One end of the claw mounting frame 121 is fixedly mounted on the telescopic column 11, and the other end of the claw mounting frame 121 is movably provided with two claw heads 122. The two claw heads 122 can grip the steel structure column 4 or release from the steel structure column 4 under power drive. Specifically, each of the tails of the two claw heads 122 is fixedly provided with a slider 123, and each slider 123 is correspondingly mounted on the claw head lead screw 125. The claw head lead screw 125 is fixedly mounted on the lead screw support seat 124 fixed on the claw mounting frame 121. The ends of 125 are all powered by a coupling 126 to a claw motor 127, which drives two claws 122 to open and close. A gear set 129 is fixedly installed on the top of the gripper mounting frame 121. The gear set 129 is powered by a rotating motor 128 fixed on the telescopic column 11. The rotating motor 128 drives the gripper mounting frame 121 to rotate around the telescopic column 11 for movement avoidance. A climbing screw 111 is installed inside the cylinder of the telescopic column 11. The telescopic rod at the lower end of the telescopic column 11 is movably fitted on the climbing screw 111. The top of the climbing screw 111 is powered by a climbing motor 112 fixed to the top of the cylinder of the telescopic column 11. The climbing motor 112 drives the telescopic rod of the telescopic column 11 to extend and retract, thereby driving the second climbing claw 13 fixed on the telescopic rod to perform the corresponding lifting and lowering action.

[0041] The gripping part of the claw 122 matches the outer contour of the steel structure column 4, ensuring that the claw 122 can firmly grip the steel structure column 4; the connecting part between the support frame 2 and the connecting column 14 is a telescopic structure; the connecting column 14 is a telescopic structure; a support cylinder 113 is fixedly installed on the upper part of the cylinder of the telescopic column 11, and the body of the climbing motor 112 is fixed on the support cylinder 113; the power head of the claw motor 127 splits the power into two through a gear assembly or a turbine assembly and then connects to the corresponding coupling 126.

[0042] The working process of this invention is as follows: The claw head 122 of the first climbing claw 12 is controlled to release the steel structure column 4, and then the telescopic rod of the telescopic column 11 is extended by the climbing motor 112. Since the second climbing claw 13 is fixed on the telescopic rod, the cylinder of the telescopic column 11 is lifted, thereby driving the truss crane 3 to rise. If the climbing height is insufficient, the claw head 122 of the second climbing claw 13 is controlled to release the steel structure column 4, and then the telescopic rod of the telescopic column 11 is shortened by the climbing motor 112. After the second climbing claw 13 is lifted, the second climbing claw 13 is controlled to grip the steel structure column 4, and then the above lifting action of the truss crane 3 is repeated. According to the actual situation, the above lifting action of the truss crane 3 can be repeated until a suitable height is reached.

[0043] When the installation machine climbs to the upper level, it controls the claw head 122 of the first climbing claw 12 to release the steel structure column 4, and then controls the rotation motor 128 to drive the gripper mounting frame 121 of the first climbing claw 12 to rotate around its own telescopic column 11 to avoid the upper crossbeam; then the climbing motor 112 drives the telescopic rod of the telescopic column 11 to extend. Since the second climbing claw 13 is fixed on the telescopic rod, the cylinder of the telescopic column 11 is lifted, which drives the first climbing claw 12 fixed on the cylinder of the telescopic column 11 to cross the crossbeam to reach the upper level. Then, it controls the claw head 122 of the first climbing claw 12 to grip the structural column 4 of the upper level.

[0044] Continue to control the claw head 122 of the second climbing claw 13 to release the steel structure column 4, and then control the rotation motor 128 to drive the gripper mounting frame 121 of the second climbing claw 13 to rotate around its own telescopic column 11 to avoid the upper crossbeam; then drive the telescopic rod of the telescopic column 11 to shorten through the climbing motor 112, lift the second climbing claw 13 and cross the crossbeam to reach the upper level, and then control the second climbing claw 13 to grip the steel structure column 4 of the upper level.

[0045] The climbing motor 112 and the rotating motor 128 are both executed automatically through a predetermined program or manually controlled. Multiple installation machines can be arranged on a steel structure building construction work surface at the same time, and the corresponding components of the four climbing frame units 1 in each installation machine move synchronously.

[0046] The present invention discloses a method for using a special installation machine for steel structure building construction, which is implemented according to the following steps:

[0047] The first step is to assemble and install the machine;

[0048] After the first layer of steel structure columns 4 are fixed, the four climbing frame units 1 are fixed to the corresponding steel structure columns 4 by their respective first climbing claws 12 and second climbing claws 13. Then, the connecting column 14 and the support frame 2 are assembled in sequence, and then the truss crane 3 is hoisted onto the support frame 2 and fixed.

[0049] The second step is to complete the construction of the steel structure building on the floor where the installation machine is located and to build the steel structure building on the next floor.

[0050] Control the truss crane 3 to perform the corresponding lifting operations;

[0051] The third step is for the truss crane 3 to begin its climbing motion;

[0052] The claw 122 of the first climbing claw 12 is controlled to release the steel structure column 4, and then the telescopic rod of the telescopic column 11 is extended by the climbing motor 112. Since the second climbing claw 13 is fixed on the telescopic rod, the cylinder of the telescopic column 11 is lifted, thereby driving the truss crane 3 to rise.

[0053] If the climbing height is insufficient, continue to control the claw head 122 of the second climbing claw 13 to release the steel structure column 4, and then drive the telescopic rod of the telescopic column 11 to shorten through the climbing motor 112. After raising the second climbing claw 13, control the second climbing claw 13 to grip the steel structure column 4, and then repeat the above lifting action of the truss crane 3. Depending on the actual situation, the above lifting action of the truss crane 3 can be repeated until a suitable height is reached.

[0054] The fourth step is for the installation machine to climb to the next floor;

[0055] The claw head 122 of the first climbing claw 12 is controlled to release the steel structure column 4, and then the rotation motor 128 is controlled to drive the gripper mounting frame 121 of the first climbing claw 12 to rotate around its own telescopic column 11 to avoid the upper crossbeam; then the telescopic rod of the telescopic column 11 is extended by the climbing motor 112. Since the second climbing claw 13 is fixed on the telescopic rod, the cylinder of the telescopic column 11 is lifted, which drives the first climbing claw 12 fixed on the cylinder of the telescopic column 11 to cross the crossbeam to the upper layer. Then the claw head 122 of the first climbing claw 12 is controlled to grip the structural column 4 of the upper layer.

[0056] Continue to control the claw head 122 of the second climbing claw 13 to release the steel structure column 4, and then control the rotation motor 128 to drive the gripper mounting frame 121 of the second climbing claw 13 to rotate around its own telescopic column 11 to avoid the upper crossbeam; then drive the telescopic rod of the telescopic column 11 to shorten through the climbing motor 112, lift the second climbing claw 13 and cross the crossbeam to reach the upper floor, and then control the second climbing claw 13 to grip the steel structure column 4 of the upper floor;

[0057] Fifth, repeat steps three and four until the steel structure construction is completed;

[0058] Step 6: Demolition;

[0059] The truss crane 3 is lifted directly from above the steel structure building by a crane, and the climbing frame unit 1 is connected to the support frame 2 to descend to the first floor by reverse operation; or it is lifted directly from above the steel structure building by a crane.

[0060] In the first step of this invention, after the truss crane 3 is hoisted onto the support frame 2 and fixed, the truss crane 3 is located above the crossbeam of the first layer.

[0061] In this invention, the climbing motor 112 and the rotating motor 128 are both executed automatically through a predetermined program or operated manually. The truss crane 3 is an unmanned remote-controlled crane. Multiple installation machines can be arranged simultaneously on a steel structure building construction work surface, and the corresponding components of the four climbing frame units 1 in each installation machine operate synchronously.

[0062] The installation machine involved in this invention includes a climbing frame unit 1, a support frame 2, and a truss crane 3. The climbing frame unit 1 is fixedly installed on different steel structure columns 4 and serves as the support part of the support frame 2. The support frame 2 is fixedly installed on the top of the climbing frame unit 1. The truss crane 3 is fixedly installed on the support frame 2 and has both rotation and lifting functions. The truss crane 3 is an existing unmanned remote-controlled structure.

[0063] This invention utilizes the characteristics of steel structure columns in prefabricated buildings to climb the climbing frame unit 1 along the steel structure columns, gradually raising the truss crane to the working surface. The lifting process is unaffected by the crossbeams, and the climbing action is simple and efficient. No special tower crane operator is required for high-altitude operations. Multiple truss cranes can be deployed simultaneously on one construction working surface, greatly improving the construction progress. The truss crane structure used is much smaller than traditional tower cranes, resulting in low equipment costs, no need for rental, and simple operation for personnel, thus reducing construction costs.

[0064] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
