Description

Technical Field

[0001] This application relates to the field of hoisting and installation tools, specifically to a hoisting and installation frame for an angle iron clamping device. Background Technology

[0002] Angle iron is a long strip of steel with two sides perpendicular to each other, forming an angle. It can be used to assemble various load-bearing components according to different structural needs, and can also be used as a connector between components. It is widely used in various building structures and engineering structures. For example, most power transmission towers in the power industry are made of angle iron. Even some power transmission towers that are not made of angle iron have crossarms made of angle iron.

[0003] Many devices are often added to power transmission towers to enable their inspection and maintenance. These devices include cameras, inertial devices, warning lights, bird deterrents, and so on.

[0004] The installation of these devices might seem like a simple manual method, involving drilling holes directly into the angle iron and securing it with fasteners. However, drilling holes in the angle iron directly affects its strength, consequently impacting the stability and lifespan of the tower. Ideally, installation should be done without drilling holes. Therefore, a clamping device that avoids drilling holes in the angle iron is currently being used, such as... Figure 1 As shown, two angle iron-like clamps are used to hold the angle iron in place, and then the two clamps are fixed with multiple bolts and nuts. Since the two clamps are separate, at least four bolts are needed between the two clamps to achieve stable clamping in order to balance the force when the clamps are fixed. This not only increases the installation difficulty of the entire clamping device, but also makes the installation of each clamping device time-consuming and inefficient.

[0005] Therefore, such as Figure 1 As shown, we have developed a quick-installation clamping device for angle iron, comprising a T-shaped sliding plate, a first hook, a second hook, a clamping bolt, a guide rod, and a connecting rod assembly. The T-shaped sliding plate includes a horizontal plate and a vertical plate, with the vertical plate positioned perpendicular to the horizontal plate. The horizontal and vertical plates have grooves on both sides of the same right angle. The first hook is located within the groove of the horizontal plate, and the second hook is located within the groove of the vertical plate. The clamping bolt is pivotally mounted on the horizontal plate and connected to the second hook. A guide rod parallel to the clamping bolt is provided on the second hook, sliding through the horizontal plate. The connecting rod assembly connects the guide rod and the first hook on the horizontal plate. This quick-installation clamping device uses only one clamping bolt, which works in conjunction with two hooks. Through a clever connection, the two hooks operate simultaneously to clamp the angle iron, enabling rapid installation.

[0006] This quick-installation clamping device can be installed on angle iron manually. However, for transmission towers, manual climbing is extremely dangerous. To ensure the safety of the workers, various safety measures must be taken in advance, and sometimes the power line needs to be shut down for the operation. There are many uncertainties and installation is inconvenient. Utility Model Content

[0007] In view of this, this application provides a hoisting and installation frame for an angle iron clamping device, which holds the quick-installation clamping device and lifts it to the angle iron of the tower where the quick-installation clamping device needs to be installed by a hoisting equipment, thereby achieving rapid installation. The whole process does not require personnel to climb to heights, making installation convenient and safe.

[0038] Example:

[0039] Please refer to the following: Figure 2 , Figure 3 , Figure 4 and Figure 5 According to one aspect of this application, one embodiment provides a hoisting and mounting frame for an angle iron clamping device, including a hoisting base plate 1, a spring pressure plate assembly 2, a locking hook assembly 3, an electric wrench assembly 4, and a lifting ring 5.

[0040] The hoisting base plate 1 is a π-shaped thick plate with an opening 11. The upper surface is used to fix and set various components. The lower surface of the hoisting base plate 1 is provided with a positioning groove 12.

[0041] The spring pressure plate assembly 2 includes a support column 21, a pressure plate 22, and a spring 23. There are two supports 21, which are respectively located on both sides of the opening 11 of the hoisting base plate 1.

The spring 23 is fixedly installed on the lower surface of the pressure plate 22, with its bottom facing the opening 11 of the hoisting base plate 1.

[0042] The locking hook assembly 3 has two sets, which are symmetrically located on both sides of the spring pressure plate assembly 2;

[0043] The locking hook assembly 3 includes a locking hook 31, a locking hook hinge seat 32, a linear telescopic drive device 33, and a linear drive device seat 34. The linear telescopic drive device 33 is an electric cylinder. The locking hook hinge seat 32 and the linear telescopic drive device seat 34 are mounted on the lifting base plate 1. The locking hook 31 is provided with a first hinge shaft 35 and a second hinge shaft 36. The locking hook 31 is hinged to the locking hook hinge seat 32 via the first hinge shaft 35. The bottom of the linear telescopic drive device 33 is hinged to the linear telescopic drive device seat 34, and the head of the linear telescopic drive device 33 is hinged to the locking hook 31 via the second hinge shaft 36. The linear telescopic drive device 33 extends and retracts, causing the locking hook 31 to rotate, thereby realizing the locking and unhooking of the locking hook.

[0044] The locking hook 31 is also provided with a reinforcing plate 37, which is located at the other end of the second hinge shaft 35. In order to increase the connection strength, the locking hook 31 and the reinforcing plate 37 are also connected together by two connecting rods 38, which are respectively located on both sides of the second hinge shaft 36.

[0045] The electric wrench assembly 4 includes an electric wrench gantry 41 and an electric wrench 42. The electric wrench gantry 41 spans across the opening 11 of the hoisting base plate 1 and is connected to the hoisting base plate 1. The electric wrench 42 is fixedly installed inside the electric wrench gantry 41. The opening 11 of the hoisting base plate 1 is located below the electric wrench 42.

[0046] The electric wrench 42 is also connected to a socket wrench to ensure that the electric wrench 42 can be connected to the clamping nut on the quick-release clamping device, so that the electric wrench 42 can tighten the clamping bolt on the quick-release clamping device.

[0047] There are four lifting rings 5, which are respectively set at the four corners of the lifting base plate 1.

[0048] It also includes a power supply box, in which a rechargeable battery pack and a remote control switch are installed. The power supply box is electrically connected to the electric wrench 42 and the linear telescopic drive device 33.

[0049] Please refer to Figure 6 , Figure 7 and Figure 8This utility model discloses a hoisting and installation frame for an angle iron clamping device. In use, the quick-release angle iron clamping device is first assembled on the ground. Specifically, the T-shaped sliding plate of the quick-release clamping device is placed against the cross-shaped positioning groove under the hoisting base plate. An electric wrench is directly connected to the clamping bolts of the quick-release clamping device. Then, the locking hook of the locking hook assembly hooks onto the bolts of the lifting lugs on the T-shaped sliding plate of the quick-release clamping device. At this time, the spring of the spring pressure plate assembly presses against the cover plate of the horizontal plate, and the spring is compressed, exerting a downward force on the horizontal plate. Thus, the hoisting and installation frame of this utility model is assembled with the quick-release clamping device. Depending on the required position of the angle iron to be installed, ropes are tied to different lifting rings. Then, a hoisting device, such as a crane or drone, is used to lift the assembly of the hoisting and installation frame and the quick-release clamping device to a high altitude, and then the quick-release clamping device is tightly attached to the angle iron.

[0050] After the quick-release clamping device is pressed tightly against the angle iron, turn on the electric wrench using the remote control. The electric wrench rotates and tightens the clamping bolt. After a period of time, the quick-release clamping device is firmly fixed to the angle iron. Then, turn off the electric wrench using the remote control and then turn on the linear telescopic drive device, i.e., the electric cylinder. The electric cylinder retracts, and the locking hook disengages. As the locking hook disengages, the spring releases its restraint and returns to its original shape, giving the hoisting installation frame of this utility model an elastic force, allowing the hoisting installation frame of this utility model to quickly spring off the quick-release clamping device and complete the installation.

[0051] This utility model provides a hoisting and installation frame for an angle iron clamping device. When combined with a quick-installation clamping device on the ground, the relevant equipment can be directly installed on the quick-installation clamping device on the ground, achieving the purpose with a single installation.

[0052] This utility model discloses an angle iron clamping device hoisting and installation frame, which, in conjunction with a hoisting device, enables unmanned high-altitude operations, greatly eliminating the risks of personnel working at heights. Especially when installing equipment on transmission towers, it significantly reduces the risks of working at heights and electric shock, and completely eliminates the need for power outages when installing equipment on transmission towers, thus improving the stability of the power grid.

[0053] The above-described specific examples are for illustrative purposes only and are not intended to limit the scope of this invention. Those skilled in the art to which this invention pertains can make various simple deductions, modifications, or substitutions based on the concept of this invention.
