Description

Technical Field

[0001] The utility model relates to the technical field of tooling, in particular to a hoisting tooling. Background Art

[0002] The large composite guide vane is a curved square structure with large size, 3-4m high, 6-7m wide, about 1m thick and weighing about 6t. The wind tunnel infrastructure has been completed when the guide vane is installed, which is equivalent to installing it in a sealed room. After installation, the top of the guide vane is only 250mm away from the top of the tunnel. Due to the capping of the tunnel, the lifting height in the tunnel is limited, and there is not enough lifting space. Common overhead cranes and tower cranes cannot be used for installation. The top of the guide vane is too close to the top of the tunnel, which is far less than the height of the car crane, and the guide vane cannot be hoisted.

[0003] Traditional steel structure guide vanes can be welded with hanging points in the middle of both sides of the product. There is a height difference of at least 3-5m between the welding hanging points and the top of the wind tunnel. It can be installed by using a ground truck crane. After installation, the hanging points on the edge of the guide vane are cut off and the surface is polished and repaired to its original state.

[0004] Due to the material characteristics of the composite guide vane (non-metallic material), it is impossible to weld the lifting point, so the lifting point can only be set at the top. The top of the guide vane is only 200mm away from the top of the cave, which cannot be achieved by conventional lifting methods. Utility Model Content

Detailed implementation manners

[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0025] As Figures 1-5 shown, a hoisting tool for a large composite deflector includes a support platform 100. A hoisting bracket 200 is installed on the support platform 100. An operation platform 300 is provided in the middle of the hoisting bracket 200. A boom 400 is provided at the top of the hoisting bracket 200. A pulley 500 is provided on the boom 400. The support platform 100 is also provided with a winch mechanism 600. The cable 601 of the winch mechanism 600 passes through the hoisting bracket 200, is lapped on the pulley 500, and is connected to the top of the deflector 900 to be hoisted.

[0026] Specifically, the support platform 100 is a flat plate structure, and the overall structure is arc-shaped, matching the profile of the deflector 900 to be hoisted. The hoisting bracket 200 is welded by steel structures. A ladder is provided on the hoisting bracket 200. The hoisting bracket 200 is divided into a lower hoisting bracket 202 and an upper hoisting bracket 201. The lower hoisting bracket 202 is installed on the support platform 100, and the upper hoisting bracket 201 is welded and fixed on the top of the lower hoisting bracket 202.

[0027] It should be noted that the lower lifting bracket 202 is transported into the test scene, and then the upper lifting bracket 201 is installed on the lower lifting bracket 202. The installation height of the test scene is limited, and it is inconvenient to transport the entire structure into the test scene. The problem of inconvenient transportation is solved by this split structure. The winch mechanism 600 lifts the guide vane 900 through the cable 601, and the operating platform 300 is provided for the staff to stand and install the guide vane 900. Since the lifting bracket 200 is relatively high, the split lifting bracket 200 makes processing more convenient. The lifting arm 400 extends from the top of the lifting bracket 200 so that when the guide vane 900 is lifted, the guide vane 900 can maintain a certain distance from the lifting bracket 200, which further facilitates operation.

[0028] Furthermore, the hoisting bracket 200, the operating platform 300, the boom 400, the pulley 500, and the hoisting mechanism 600 are each provided in pair.

[0029] Specifically, the two hanging brackets 200 are connected via a connecting bracket 203 .

[0030] It should be noted that the hanging bracket 200 is a main load-bearing structure, which is divided into left and right sides, and the middle and bottom are connected and fixed into one body to improve the overall rigidity.

[0031] Further, the supporting platform 100 is movably disposed on the ground, and the hanging bracket 200 is movably disposed on the supporting platform 100 .

[0032] Specifically, the support platform 100 is movably disposed on the ground through the first moving assembly 700 , and the hanging bracket 200 is movably disposed on the support platform 100 through the second moving assembly 800 , and the moving direction of the support platform 100 is perpendicular to the moving direction of the hanging bracket 200 .

[0033] It should be noted that the installation position can be adjusted by movement, thereby improving the installation accuracy and convenience of the guide plate 900. In addition, the vertical phase of the moving direction can achieve adjustment in the XY direction, thereby further improving the installation accuracy and convenience.

[0034] Further, such as Figure 6 As shown, a pair of first bearing seats 701 are installed on the support platform 100 , and a pair of moving wheels 703 connected via a first rotating shaft 702 are installed on the first bearing seats 701 , and the first rotating shaft 702 is driven by a first motor 704 .

[0035] Specifically, the first bearing block 701 is fixed on the top surface of the support platform 100. The first rotating shaft 702 is arranged through the two first bearing blocks 701. Two moving wheels 703 are installed at both ends of the first rotating shaft 702. A notch through which the lower part of the moving wheel 703 passes is provided on the support platform 100. A driven wheel 705 is also fixedly sleeved on the first rotating shaft 702. A driving wheel 706 connected to the output shaft of the first motor 704 and in belt drive connection with the driven wheel 705 is provided. The first motor 704 is a servo motor.

[0036] It should be noted that the first motor 704 drives the driving wheel 706 to rotate, the driving wheel 706 drives the driven wheel 705 to rotate, the driven wheel 705 drives the first rotating shaft 702 to rotate, and the first rotating shaft 702 drives the two moving wheels 703 to rotate to achieve movement.

[0037] Furthermore, a number of flow strip rollers 101 are provided at the bottom of the support platform 100.

[0038] Specifically, a number of flow strip rollers 101 are installed side by side inside the bottom of the support platform 100.

[0039] It should be noted that the support wheels 101 play a role in supporting the whole and can also move. The weight of the whole is shared by a number of support wheels 101 under the action of the groove plate 102 to ensure the stability of the support platform.

[0040] Furthermore, as Figure 7 shown, a slide rail 801 is provided on the support platform 100. The hoisting bracket 200 is installed on the slide rail 801. A lead screw 803 transmission mechanism for driving the hoisting bracket 200 to slide along the slide rail 801 is provided on the support platform 100. The lead screw 803 transmission mechanism is driven by a second motor 807.

[0041] Specifically, a pair of slide rails 801 are provided at the bottom of each hoisting bracket 200. Sliders 802 are correspondingly provided at the bottom of the hoisting bracket 200. Both ends of the lead screw of the lead screw 803 transmission mechanism are installed on the second bearing block 806. The second bearing block 806 is installed on the support platform 100. The nut 804 of the lead screw 803 transmission mechanism is connected to the hoisting bracket 200 through a connecting block 805. The second motor 807 is used to drive the lead screw to rotate, and drives the hoisting bracket 200 to slide along the slide rail 801 through the nut 804 and the connecting block 805. The second motor 807 is a servo motor.

[0042] It should be noted that the second motor 807 is used to drive the lead screw to rotate, and drives the hoisting bracket 200 to slide along the slide rail 801 through the nut 804 and the connecting block 805. Such a design can easily realize the movement between hoistings, thus ensuring the installation accuracy and having a simple structure.

[0043] Furthermore, a counterweight 103 is provided on the support platform 100.

[0044] Specifically, the counterweights 103 are arranged on both sides at the rear end of the support platform 100.

[0045] It should be noted that the design of the counterweights 103 improves the stability of the tooling.

[0046] Furthermore, support feet 104 are also provided on the support platform 100.

[0047] Specifically, the support feet 104 are arranged at the four corners of the support platform 100.

[0048] It should be noted that the support feet 104 provide support after the support platform 100 has moved into place, improving the stability during the use of the tooling.

[0049] Working principle: When this embodiment is in use, start the first motor 704 to drive the moving wheels 703 to rotate, move the hoisting tooling in front of the diversion vane 900, and stop the first motor 704; use the cable 601 to hook the lifting point of the diversion vane 900, start the hoisting mechanism 600 to lift the diversion vane 900 to a height of 6 - 7M, and stop the hoisting machine; start the first motor 704 again to drive the moving wheels 703 to rotate, move the hoisting tooling to the installation position of the diversion vane 900, and stop the first motor 704; start the second motor 807 to drive the hoisting bracket 200 to move horizontally and fine-tune it along the slide rail 801. After adjusting to the correct installation position, stop the second motor 807; install the diversion vane 900; start the first motor 704 again, and move the hoisting tooling to the next diversion vane 900 for hoisting.

[0050] The description of the above embodiments is only used to help understand the method and its core idea of the present invention. It should be pointed out that for those of ordinary skill in the art of this technology, without departing from the principle of the present invention, several improvements and modifications can still be made to the present invention, and these improvements and modifications also fall within the protection scope of the claims of the present invention.
