For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0021] Embodiment 1:

[0022] The main structure of this embodiment is as follows: Figure 1 As shown, it includes a crossbeam 1, a counterweight block 2 is movably connected to one side of the crossbeam 1, a sling 3 that can slide on the crossbeam 1 is arranged in the middle of the crossbeam 1, and a plurality of supporting mechanisms 4 that can be movably connected to the medium-sized frame are arranged at the other end of the frame 1.

[0023] The specific implementation process is as follows: according to the weight of the medium-sized frame to be hoisted, a counterweight block 2 of matching weight is movably installed at one end of the beam 1, and a suitable number of support mechanisms 4 are installed at the other end according to the length of the center frame. The medium-sized frame to be hoisted is fixed by the support mechanism 4, and then the sling 3 in the middle of the beam 1 is adjusted to balance the counterweight block 2 and the medium-sized frame. The sling 3 is then lifted by the crane hook to steadily lift the medium-sized frame into the U-shaped space.

[0024] Embodiment 2:

[0025] Based on the above embodiment, this embodiment further defines the structure of the crossbeam 1, such as Figure 1As shown, the crossbeam 1 is a rectangular steel tube. The main advantage of the crossbeam 1 being a rectangular steel tube is that the planes of the rectangular steel tube are flat, so that the counterweight 2 and the support mechanism 4 can be installed more easily. In addition, the rectangular steel tube is not easy to rotate, so the movement of the sling 3 on the crossbeam 1 is relatively stable, and during the hoisting process of the sling 3, the sling 3 is not easy to deviate on the rectangular steel tube, which can ensure the stability when hoisting a medium-sized frame. Steel tubes of other shapes can also be used as crossbeams 1 if the support strength is met. Here, rectangular steel tubes are preferably used as crossbeams 1. The other parts of this embodiment are the same as the above embodiment and will not be repeated.

[0026] Embodiment 3:

[0027] Based on the above embodiment, this embodiment further defines the connection relationship between the counterweight block 2 and the crossbeam 1, such as Figure 1 As shown, the side wall of the cross beam 1 movably connected to one end of the counterweight 2 is provided with at least one transition plate 5, and the transition plate 5 is L-shaped. The transition plate 5 is fixed to the side wall of the cross beam 1 by screws, and the transition plate 5 is movably connected to the counterweight 2 by screws. The setting of the transition plate 5 is mainly to fix the counterweight 2 at one end of the cross beam 1. The transition plate 5 is L-shaped. If the cross beam 1 is a rectangular steel pipe, the transition plate 5 and the side wall of the cross beam 1 have a large contact area, and the friction force is large. Only one screw is needed to better achieve the fixation of the transition plate 5 and the side wall of the cross beam 1. Similarly, the contact area between the transition plate 5 and the counterweight 2 is also large. In the case of large friction force, the transition plate 5 and the counterweight 2 can be fixed by only one screw, which can simplify the installation process of the counterweight 2 and the cross beam 1. If the cross beam 1 is not a rectangular steel tube, the transition plate 5 cannot have a large contact area with the cross beam 1, and at least two screws are required to fix the transition plate 5 to the side wall of the cross beam 1 to ensure the stable fixation of the transition plate 5 and the cross beam. Therefore, the cross beam 1 is preferably a rectangular steel tube, and other shapes of cross beams 1 can also be selected under the premise of ensuring the stability of the transition plate 5 and the cross beam. The other parts of this embodiment are the same as the above embodiment and will not be repeated.

[0028] Embodiment 4:

[0029] Based on the above embodiment, this embodiment further defines the connection relationship between the counterweight block 2 and the crossbeam 1, such as Figure 1As shown, at least one set of transition plates 5 are symmetrically arranged on both sides of the cross beam 1 that is movably connected to one end of the counterweight 2, and each set of transition plates 5 is two, and they are symmetrically arranged with the cross beam 1 as the axis. Since the counterweight 2 is fixed under the cross beam 1 through the transition plates 5, in order to ensure the stability of the fixation of the counterweight 2, it is preferred that a set of transition plates 5 are stacked on both sides of the cross beam 1, and each set of transition plates 5 is two, which are used to fix the counterweight 2 at the bottom together, while ensuring that the counterweight 2 is fixed firmly, the weight of the counterweight 2 is evenly distributed at the bottom of the cross beam 1. In actual use, the number of sets of transition plates 5 can be increased according to the length and total amount of the counterweight 2, and the spacing between each set of transition plates 5 is equal, so as to ensure that the weight provided by the fixed counterweight 2 at the bottom is evenly distributed on the cross beam 1, and the cross beam 1 is bent and deformed due to uneven force. The other parts of this embodiment are the same as the above embodiment and will not be repeated.

[0030] Embodiment 5:

[0031] Based on the above embodiments, this embodiment further defines the specific structure of the support mechanism 4, such as Figure 1 As shown, the support mechanism 4 includes a support frame 41 which is perpendicular to the beam 1 and fixed to the upper surface of the beam 1, and the lower parts of both ends of the support frame 41 are fixedly connected with vertically arranged fixing rods 42, and the lower part of each fixing rod 42 is provided with a mounting plate 43 for fixing to the medium-sized frame. The main function of the support mechanism 4 is to fix the medium-sized frame that needs to be hoisted. Therefore, fixing rods 42 are set at both ends of the support frame 41 of the support mechanism 4, and the mounting plates 43 at the bottom of the fixing rods 42 are used to fix the medium-sized frame. The length of the support frame 41 is generally adapted to the width of the medium-sized frame. Therefore, the mounting plates 43 at the bottom of the fixing rods 42 at both ends of the support frame 41 can be just fixed on both sides of the medium-sized frame, so as to achieve stable fixation of the medium-sized frame. In order to further ensure the stability of the hoisting of the medium-sized frame, at least two groups of support mechanisms 4 are set at one end of the crossbeam 1, and the spacing between adjacent support mechanisms 4 is equal, so that the stability when hoisting the medium-sized frame can be greatly improved, so that it can be relatively stable when hoisted into the U-shaped space, avoiding adverse effects on the surrounding environment. The other parts of this embodiment are the same as the above-mentioned embodiments and will not be repeated.

[0032] Embodiment 6:

[0033] Based on the above embodiments, this embodiment further defines the specific structure of the support mechanism 4, such as Figure 1As shown, the middle part of the support frame 41 is fixed on the upper surface of the beam 1, and the fixing rods 42 on both sides of the support frame 41 are symmetrically arranged with the beam 1 as the axis. The middle part of the support frame 41 is fixed on the beam 1, and the fixing rods 42 are symmetrically arranged with the beam 1 as the axis, mainly to ensure that the force on both ends of the support frame 41 is uniform. In this way, when hoisting a medium-sized frame, the mounting plates 43 at the lower parts of the fixing rods 42 on both sides are also fixed on both sides of the medium-sized frame, so that the medium-sized frame can be hoisted more stably. In addition, since the middle part of the support frame 41 is fixed on the beam 1, it can ensure that the upper part of the beam 1 is uniformly stressed, and further ensure the hoisting stability of the medium-sized frame. The support frame 1 can be fixed to the upper surface of the beam 1 by welding, or two positioning pins can be set on the upper part of the beam 1, and the support frame 41 is placed between the two positioning pins to achieve the fixation of the support frame 41 and the beam 1. The other parts of this embodiment are the same as the above embodiment and will not be repeated.
