They are widely used in buildings such as industrial production, commercial services, and cultural and artistic public facilities, such as large workshops, warehouses, logistics centers, commercial complexes, etc. Due to the high precision requirements of steel structures, the size and position deviation of the components need to be strictly controlled during the installation process. It is necessary to ensure that each component is accurately positioned and firmly fixed at the construction site to ensure the stability and safety of the overall structure. Temporary supports need to be set up to bear part of the load to prevent the structure from becoming unstable or deformed.

DETAILED DESCRIPTION

[0030] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0031] Embodiment 1, as Figure 1-2 As shown, an assembled portal frame auxiliary installation support device includes a mobile base 1, an outer frame 3 is fixedly connected to the outer surface of the mobile base 1, a support mechanism 5 is fixedly connected to the upper end of the mobile base 1, a motor 4 is fixedly connected to the lower side of the support mechanism 5, a clamping mechanism 7 is provided in the middle of the lower side of the support mechanism 5, the lower left side of the clamping mechanism 7 is fixedly connected to the output end of the motor 4, a belt 2 is provided in the middle of the left side of the clamping mechanism 7, and a working mechanism 6 is fixedly connected to the upper side of the support mechanism 5.

[0032] It should be noted that the specific installation method of the motor 4, the circuit connection method and the control method in the present invention are all conventional designs, which are conventional design means of designers. The mobile base 1 is composed of key components such as wheels, brakes, and a chassis, which enable the device to move flexibly and fix the wheels through brakes when it needs to stop to prevent accidental movement or sliding and stabilize them. The outer frame 3 increases the weight of the bottom of the device and enhances the stability of the device.

[0033] Firstly, by moving the base 1, the device is moved to a suitable position at the construction site and stabilized. The motor 4 can be started in cooperation with the belt 2 to enable the clamping mechanism 7 to provide auxiliary support to the column. That is, when the staff lifts the column by a crane and needs to install the column, the clamping mechanism 7 can be used to clamp and fix the lifted column to be installed to prevent accidents and facilitate the construction personnel to fix and install the column with the embedded anchor bolts. Secondly, the working mechanism 6 can be used to provide auxiliary support to the beam so that the construction personnel can install the beam. In addition, during the entire construction process, the construction personnel can install the connecting parts in the working mechanism 6 and subsequently install the enclosure system, so that the device can be used in the entire construction process and has a wide range of applications.

[0034] In order to achieve the purpose of supporting the working mechanism 6 and the clamping mechanism 7 and facilitating the construction personnel to board the working mechanism 6, as shown in FIG. Figure 3 As shown, the support mechanism 5 includes a base frame 51, a support frame 55 is fixedly connected to the upper end of the base frame 51, a connecting plate 52 is fixedly connected to the left side of the inner cavity of the base frame 51, a ladder group 54 is fixedly connected to the middle of the left side of the outer surface of the support frame 55, four reinforcing columns 53 are fixedly connected to the rectangular array on the lower side of the outer surface of the support frame 55, the lower ends of the four reinforcing columns 53 are fixedly connected to the upper end of the base frame 51, and the middle of the upper end of the connecting plate 52 is fixedly connected to the lower end of the motor 4.

[0035] First, by installing a base frame 51, the weight of the bottom of the device is increased and the stability of the device is enhanced. By installing a support frame 55, the entire device is supported, and reinforcing columns 53 are installed at the four corners below the support frame 55 to provide auxiliary support for the support frame 55, further enhancing the stability of the support frame 55 installed on the base frame 51, and the clamping mechanism 7 is installed through the base frame 51 and the support frame 55, and the working mechanism 6 is installed through the support frame 55, and a ladder group 54 is installed in the middle of the left side of the support frame 55, so that construction personnel can enter the working mechanism 6 through the ladder group 54, thereby achieving the purpose of supporting the working mechanism 6 and the clamping mechanism 7 and facilitating construction personnel to board the working mechanism 6.

[0036] Further explanation, such as Figure 4 As shown, the ladder group 54 includes two L-shaped connecting rods 541, and the upper ends of the two L-shaped connecting rods 541 are fixedly connected to a straight ladder 542. The upper end of the straight ladder 542 is fixedly connected to a front and rear symmetrical side railing 543, and the right ends of the two L-shaped connecting rods 541 are fixedly connected to the lower left part of the outer surface of the support frame 55.

[0037] In detail, the straight ladder 542 is installed on the support frame 55 and the working mechanism 6 through the L-shaped connecting rod 541 and the side rail 543. The construction workers climb up the working mechanism 6 by climbing the straight ladder 542. When the height of the working mechanism 6 is adjusted, the right outer surface of the side rail 543 will slide upward to a certain height. The construction workers can still enter the working mechanism 6 through the side rail 543, so that when the height of the working mechanism 6 is adjusted, it will not affect the construction workers from entering the working mechanism 6 to carry out work.

[0038] Embodiment 2: Based on Embodiment 1, this embodiment achieves the purpose of auxiliary support for the column. Figure 5 and Figure 6 As shown, the clamping mechanism 7 includes two fixed sleeves 72, and the middle parts of the inner cavities of the two fixed sleeves 72 are rotatably connected with rotating rods 76. The inner cavities of the two fixed sleeves 72 are rotatably connected with front and rear symmetrical threaded rods 74. The ends of the two threaded rods 74 on the same side that are close to each other and the middle parts of the outer surfaces of the rotating rods 76 are fixedly connected with bevel gears 75. The outer surfaces of the three bevel gears 75 on the same side are meshed and connected. The outer surfaces of the two threaded rods 74 on the front side and the outer surfaces of the two threaded rods 74 on the rear side are commonly provided with a clamping group 73. The left ends of the two rotating rods 76 pass through the inner cavities of the fixed sleeves 72 on the same side and are fixedly connected with transmission wheels 71. The outer surfaces of the two transmission wheels 71 are commonly wound around the belt 2. The left end of the lower transmission wheel 71 is fixedly connected to the output end of the motor 4. The lower end of the lower fixed sleeve 72 is fixedly connected to the upper end of the base frame 51. The lower end of the upper fixed sleeve 72 is fixedly connected to the middle part of the support frame 55.

[0039] First, the clamping mechanism 7 can be installed on the support frame 55 and the base frame 51 through two fixed sleeve plates 72. When the column needs to be supported auxiliaryly, the motor 4 is started to drive the transmission wheel 71 on the lower side to rotate. With the cooperation of the belt 2, the transmission wheel 71 on the upper side is driven to rotate. The rotation of the two transmission wheels 71 drives the rotating rod 76 fixedly connected to them to rotate together. With the cooperation of the bevel gear 75, the threaded rods 74 on the front and rear sides rotate in the inner cavity of the fixed sleeve plate 72, thereby driving the clamping groups 7 on the front and rear sides. 3 are moved towards each other to a suitable position, and the column is clamped and fixed by the clamping group 73 to prevent the column from shaking accidentally. The extension of the clamping groups 73 on the front and rear sides prevents the column from being too close to the support frame 55, which is inconvenient for installing the column and the embedded anchor bolts. In addition, the front and rear symmetrical design of the clamping group 73 not only allows the front and rear sides of the device to clamp and fix the column for auxiliary support, but also when the device clamps and fixes a single column, the extension of the clamping group 73 on the other side can increase the balance of the device, thereby improving the stability of the device, and finally achieving the purpose of auxiliary support for the column.

[0040] Further explanation, such as Figure 7 As shown, the two clamping groups 73 each include a fixed sleeve 731, the opposite surfaces of the two fixed sleeves 731 are fixedly connected with a fixed plate 732 symmetrical up and down, the middle of the opposite surfaces of the two fixed sleeves 731 are fixedly connected with a sliding sleeve 735, the inner cavities of the two sliding sleeves 735 are slidably connected with a slide rail plate 734, the lower ends of the two slide rail plates 734 are fixedly connected with a hydraulic rod 3 733, the two hydraulic rods 3 733 are fixedly connected to the lower sides of the opposite surfaces of the two fixed sleeves 731 on one side away from each other, four sliding grooves 737 are opened in the middle of the opposite surfaces of the two fixed sleeves 731, and the inner cavities of the two fixed sleeves 731 are slidably connected with left and right Symmetrical clamping plates 738, two sliding columns 736 are fixedly connected to one side of the two clamping plates 738 on the same side close to the sliding rail plate 734, the outer surfaces of the four sliding columns 736 on the same side are slidably connected to the inner cavity of the sliding rail plate 734, the outer surfaces of the two fixed plates 732 on the front side are slidably connected to the front sides of the inner cavities of the two fixed sleeve plates 72 respectively, the inner cavities of the two fixed plates 732 on the front side are meshed with the front sides of the outer surfaces of the two threaded rods 74 respectively, the outer surfaces of the two fixed plates 732 on the rear side are slidably connected to the rear sides of the inner cavities of the two fixed sleeve plates 72 respectively, and the inner cavities of the two fixed plates 732 on the rear side are meshed with the rear sides of the outer surfaces of the two threaded rods 74 respectively.

[0041] It should be noted that the specific installation method of the hydraulic rod 733, the circuit connection method and the control method in the present invention are all conventional designs and are conventional design means of designers.

[0042] In detail, when the threaded rods 74 on the front and rear sides rotate, the fixed plates 732 on the front and rear sides will drive the fixed sleeve plate 2 731 to move towards each other to the appropriate position. At this time, the hydraulic rod 3 733 drives the slide plate 734 to slide downward in the inner cavity of the slide sleeve 735, and drives the two symmetrical sliding columns 736 on the left and right to slide away from each other in the inner cavity of the sliding groove 737 on the same side, thereby driving the two clamping plates 738 in the inner cavity of the fixed sleeve plate 2 731 to slide away from each other and unfold, so that the column is located between the two clamping plates 738, and then the hydraulic rod 3 733 drives the slide plate 734 to slide upward in the inner cavity of the slide sleeve 735, so that the two clamping plates 738 clamp and fix the column, thereby achieving the purpose of clamping and fixing the column for auxiliary support.

[0043] Embodiment 3: Based on Embodiment 1 and Embodiment 2, this embodiment achieves the purpose of auxiliary support for the beam, such as Figure 8 As shown, the working mechanism 6 includes a base plate 61, a hydraulic rod 62 is fixedly connected to the middle of the lower end of the base plate 61, support sleeve rods 63 are fixedly connected to the four corners of the lower end of the base plate 61, the inner cavities of the four support sleeve rods 63 are slidably connected to pillars 64, the upper ends of the four pillars 64 and the output end of the hydraulic rod 62 are commonly fixedly connected to a working group 65, and the lower end of the base plate 61 is fixedly connected to the upper end of the support frame 55.

[0044] It should be noted that the specific installation method of the hydraulic rod 62, the circuit connection method and the control method in the present invention are all conventional designs, which are conventional design means of designers. The right sides of the lower ends of the two side rails 543 are fixedly connected to the middle of the left side of the upper end of the bottom plate 61.

[0045] First of all, the working group 65 can be used to provide auxiliary support for the beam, which not only achieves the purpose of auxiliary support for the beam, but also allows construction personnel to climb onto the working group 65 to install connectors and subsequently install the enclosure system, so that the device can be used in the entire construction process. When the height is not enough, the hydraulic rod 62 can be started to drive the working group 65 to move upward to a suitable position, and through the coordinated use of the support 64 and the support sleeve 63, its stability can be increased.

[0046] Further explanation, such as Fig. 9 and Fig.10 As shown, the working group 65 includes a bottom plate 651, wherein the four corners of the lower end of the bottom plate 651 are fixedly connected to the upper ends of four pillars 64 respectively, the middle part of the lower end of the bottom plate 651 is fixedly connected to the output end of the hydraulic rod 1 62, the middle part of the left end of the bottom plate 651 is fixedly connected with a front-to-back symmetrical clamping sleeve 652, the middle part of the upper end of the bottom plate 651 is fixedly connected with a support column 653, the middle part of the inner cavity of the support column 653 is fixedly connected with the hydraulic rod 2 654, the inner cavity of the support column 653 and the output end of the hydraulic rod 2 654 are jointly provided with a U-shaped top frame 655, the upper end of the bottom plate 651 is fixedly connected with a guardrail 656, the front part of the left side of the guardrail 656 is provided with a mounting groove 658, the inner cavity of the mounting groove 658 is slidably connected with a locking rod 659, the rear part of the left side of the guardrail 656 is provided with a locking groove 657, and the inner cavities of the two clamping sleeves 652 are slidably connected with the two side rails 543 respectively.

[0047] It should be noted that the specific installation method of the hydraulic rod 2 654, the circuit connection method and the control method in the present invention are all conventional designs, which are conventional design means of designers. Three grooves are opened on the upper end of the support column 653. The groove in the middle is used to install the hydraulic rod 2 654, and the grooves on the front and rear sides are used to install the U-shaped top frame 655 together.

[0048] In detail, the two clamping sleeves 652 are respectively sleeved on the right side of the outer surface of the two side rails 543. When the hydraulic rod 1 62 drives the bottom plate 2 651 to move upward, the clamping sleeve 652 will slide upward on the outer surface of the side rail 543. The construction personnel enter the bottom plate 2 651 through the straight ladder 542 and the side rail 543, and pull the locking rod 659 to slide backward and get stuck in the inner cavity of the locking groove 657 and then rotate it ninety degrees to lock it, so as to prevent the construction personnel from exceeding the range of the guardrail 656 and falling off the bottom plate 2 651. The construction personnel can install the connecting parts and the subsequent installation of the enclosure system on the bottom plate 2 651 and under the protection of the guardrail 656 and the locking rod 659. When it is necessary to support the beam, it is necessary to start the hydraulic rod 2 654 to drive the U-shaped top frame 655 to slide upward in the inner cavity of the support column 653 to the lower end of the beam. Through the cooperation of the support column 653 and the hydraulic rod 2 654, the U-shaped top frame 655 assists in supporting the beam.
