technical field

The invention relates to the field of civil engineering experiments, in particular to an auxiliary device of a chain hoist.

Background technique

When conducting experimental research on anchor rods in the civil engineering laboratory, it is necessary to pre-embed a rod in the mold before pouring concrete, and then fill in the concrete and pull out the pre-embedded rod when the concrete is initially set. At this time, there is also a large occlusal force between the concrete and the embedded pipe, and the embedded pipe needs to be pulled out with the help of a chain hoist. When using the chain hoist, a firm fixing point is required, which has a great restriction on the placement of the concrete mold. At this time, it is necessary to design a simple device that can use the pulled object itself as the fixing point, which can remove this limitation. .

Rod, install the first spring button at the other end 50mm away from the end, the rest are installed one by one according to the spacing of 100mm, a total of 8 are installed, the right part is a topless length × width × height = 65mm × 65mm × 1000mm A square long rod, the bottom of the rod has a screw hole with a diameter of 30mm, and the other side is provided with a corresponding small hole according to the corresponding position of the spring button.

Further, the telescopic rod is composed of two parts, which are respectively a thin rod with a diameter of 40 mm and a length of 500 mm and a thin hollow rod with a diameter of 42 mm and a length of 500 mm.

Further, the fixed angle steel has an equilateral angle steel with a side length of 65 mm and a cut length of 65 mm, and a screw hole with a diameter of 30 mm is drilled on both sides of the angle steel.

Further, the base is a steel plate with a side length of 1000mm and a thickness of 40mm, and two square grooves with a side length of 65mm and a depth of 20mm are installed at the bottom of the four reels at the top center axis position.

The beneficial effects of the above solution are: using the device can use the concrete itself as a support point, which solves the huge limitation on the placement of concrete molds in the prior art, and can also install the device and the base for the transportation of goods. To achieve the ideal effect of a device with multiple uses.

Detailed ways

As shown in the figure, a chain hoist auxiliary device includes a top plate 1 , a support frame 2 , a telescopic rod 3 , a fixed angle steel 4 , a hand screw 5 and a base 6 . The top plate 1 is an iron plate with length×width×thickness=1000mm×400mm×40mm, and there is a rectangular hole with length×width=900mm×40mm at the long central axis of the iron plate. The support frame 2 consists of two parts, the left part 2-1 is a long square rod with a length x width x height = 60mm x 60mm x 1000mm, and a threaded rod with a diameter of 30mm and a length of 80mm is installed at the rod end. Thin rod, install the first spring button at the other end 50mm away from the end, the rest are installed one by one according to the spacing of 100mm, a total of 8 are installed, the right part 2-2 is a length × width × height = 65mm × 65mm × 1000mm long square rod without top, with a 30mm diameter screw hole on the bottom of the rod. The two parts of the support frame 2 are assembled together, and the total assembly length of the support frame 2 can be adjusted by using a spring button. The threaded thin rod end of the left part 2-1 is placed in the rectangular hole of the top plate 1 and fixed with the hand screw 5, so that the effect of adjusting the distance between the two supporting frames 2 can be achieved. The telescopic rod 3 is composed of two parts, which are a thin rod with a diameter of 40 mm and a length of 500 mm and a hollow thin rod with a diameter of 42 mm and a length of 500 mm. After the two parts are assembled, they are installed on the two support frames 2 , and the telescopic rod 3 can be freely stretched when the distance between the support frames 2 is adjusted. The fixed angle steel 4 has an equilateral angle steel with a side length of 65 mm and an intercepted length of 65 mm, and a screw hole with a diameter of 30 mm is drilled on both sides of the angle steel. The two fixed angle steels 4 are respectively installed on the bottoms of the two supporting frames 2 by screws, as shown in FIG. 1 .

The invention described in this example includes the following steps during installation and use:

During the operation of pulling out the embedded rod, the support frame 2 is assembled with the top plate 1 through the hand screw 5, and the fixing angle steel 5 is installed on the bottom of the support frame 2 through the screw, Adjust the length of the support frame to an appropriate position. Place this device in front of the concrete being pulled, loosen the hand screw 5 and adjust the distance between the support frames 2 so that the two fixed angle steels 5 are just attached to the edge of the concrete front section, and then Turn the screws on the fixed angle steel 5 to further fix the device on the pulled concrete. Finally, the upper hook of the chain hoist is hung on the telescopic rod 3, and the lower hook is hung on the pulled pre-embedded rod to pull the chain of the chain hoist to pull out the embedded rod.

When carrying out the transportation of goods, it is only necessary to remove the fixed angle steel 5 on the above-mentioned installed device, and adjust the distance between the support frames 2 so that they are just placed on the slot of the base 6, The device is mounted on the base 6 upright. Then, the upper hook of the handle hoist is hung on the telescopic rod 3 , the lower hook is hung with the transported goods, and the height of the support frame 2 is adjusted.
