For example, if a 90T crawler crane is used to lift a steel cage, the steel wire rope of the crawler crane needs to be matched with the lifting rod on the steel cage to lift the steel cage. However, one end of the ordinary lifting rod is directly welded to the main bar of the steel cage, and the other end is welded into a lifting ring. The position and number of the steel cage where the lifting rod is located are different for different lengths of the steel cage. Therefore, the repeated welding of the lifting rod during the pile foundation construction process consumes a lot of manpower.

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] A steel cage hoisting device for pile foundation construction, such as Figure 1 and Figure 2 , including a plurality of arc-shaped hangers 2 distributed along the circumference of the outer wall of the steel cage 1, the plurality of arc-shaped hangers 2 are all in the same plane and the plurality of arc-shaped hangers 2 in the same plane form a group of hangers 2, the outer wall of the steel cage 1 has a plurality of groups of hangers 2, and each group of hangers 2 is detachably connected to the outer wall of the steel cage 1 through a mounting piece.

[0024] like Figure 1 and Figure 2 The steel cage 1 is transported to the site by a homemade simple gun carriage and hoisted as a whole by a crawler crane. Several sets of lifting bars 2 are selected and installed according to the length of the steel cage 1. At this time, each set of lifting bars 2 is installed on the outer wall of the steel cage 1 through a mounting piece, which is convenient for users to install and remove the lifting bars 2, reduce manpower welding of the lifting bars 2 to the steel cage 1, and facilitate disassembly and assembly. In order to meet the lifting requirements of the steel cage 1 under the most unfavorable conditions, it is planned to use a 90T crawler crane for the lifting construction of the steel cage 1. At this time, the hook on the wire rope of the crawler crane is connected with the lifting bar 2, which makes it easier to lift the steel cage 1.

[0025] For example, a 10m steel cage 1 has three groups of lifting bars 2, one of which is close to the upper end of the steel cage 1 when it is in a vertical state and is the main lifting point. The other two groups of lifting bars 2 are 4 to 6 meters apart and are auxiliary lifting points. Both the main lifting point and the auxiliary lifting point are hooked with the wire rope of the crawler crane. After the steel cage 1 is lifted, the main lifting point is slowly hooked and lifted, and the auxiliary lifting point cooperates to keep the steel cage 1 0.5m away from the ground, and finally makes the steel cage 1 vertical to the ground. When the steel cage 1 goes down to the auxiliary lifting point, the user removes the lifting bars 2 at the auxiliary lifting point on the steel cage 1, and then stays away from the lifting operation range.

[0026] like Figure 1 and Figure 2The mounting parts include two arc-shaped reinforcing steel plates 21 sleeved on the outer wall of the steel cage 1, a group of hanging rods 2 are evenly distributed on the outer walls of the two arc-shaped reinforcing steel plates 21, at this time, the hanging rods 2 can be fixedly connected to the outer walls of the reinforcing steel plates 21, the opposite ends of the two reinforcing steel plates 21 are connected by a connecting piece, and the inner walls of the two reinforcing steel plates 21 are provided with an annular rubber pad 22. The rubber pad 22 is an EPDM rubber pad 22. The EPDM rubber pad 22 is wear-resistant and has a long service life, which is convenient for repeated use of the mounting parts, and can be bent arbitrarily, so as to be conveniently installed on the inner wall of the arc-shaped reinforcing steel plate 21. The number of a group of hanging rods 2 is four and they are distributed on the two reinforcing steel plates 21 in pairs.

[0027] like Figure 1 and Figure 2 The connecting piece includes a connecting plate 23 arranged on the opposite side of the two reinforcing steel plates 21. The two opposite connecting plates 23 are connected by a connecting rod 231. One end of the connecting rod 231 is fixed on one of the connecting plates 23, and the other end passes through the other connecting plate 23 and a locking block 232 is threadedly connected to the end that passes through. At this time, the size of the hole opened on the connecting plate 23 for the connecting rod 231 to pass through is larger than the size of the connecting rod 231, so that the connecting rod 231 can pass through easily.

[0028] like Figure 1 and Figure 2 The working principle of the mounting parts is as follows: the two reinforcing steel plates 21 are sleeved on the outer wall of the steel cage 1, and the connecting rod 231 passes through another connecting plate 23, and then the locking block 232 is rotated to make the locking block 232 conflict with the connecting plate 23, thereby limiting the movement of the two relative connecting plates 23. In this process, the two reinforcing steel plates 21 are gradually locked on the outer wall of the steel cage 1, so that the rubber pad 22 is compressed, thereby increasing the friction between the reinforcing steel plate 21 and the steel cage 1, so that the position of the reinforcing steel plate 21 is stable.

[0029] like Figure 3 and Figure 4 In addition, the sling 2 can also be detachably connected to the reinforcing steel plate 21. The sling 2 is provided with extension plates 24 distributed along the length direction of the steel cage 1 at both ends of the arc. The reinforcing steel plate 21 is provided with a through hole 25 for the arc portion of the sling 2 to pass through, which is convenient for hooking with the wire rope. The extension plate 24 is an arc plate and is provided with a plurality of embedding grooves 26 for the steel bars on the steel cage 1 to be embedded. The rubber pad 22 is provided with a placement groove 27 for the extension plate 24 to be placed. An anti-skid rubber ring (not shown) is provided on the hole wall of the through hole 25. When the arc portion of the sling 2 passes through the through hole 25, it is tightly in contact with the anti-skid rubber ring.

[0030] like Figure 3 and Figure 4At this time, when installing the hanger 2, first install the arc-shaped part of the hanger 2 into the through hole 25, so that the hanger 2 protrudes out of the through hole 25. At this time, the extension plate 24 enters the placement groove 27, and then the reinforcement steel plate 21 is put on the outer wall of the steel cage 1. At this time, the steel bars on the steel cage 1 enter the embedded groove 26 to increase the connection between the processed steel plate and the steel cage 1.

[0031] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
