The following description of the embodiments with reference to the drawings is exemplary and intended to explain the utility model, but cannot be understood as limiting the utility model.

[0032] See also Figure 1 to Figure 3 As shown, an embodiment of the utility model provides a slot-type cross hanger, comprising a first support plate 1 and a second support plate 2 arranged in a cross shape.

[0033] See also Figure 4 As shown, the first support plate 1 includes a first body 101, and first hanging hook holes 102 are respectively provided at both ends of the first body 101. The middle part of the first body 101 protrudes upward to form a first limiting boss 103. A hanging seat 104 is provided on the first limiting boss 103. The hanging seat 104 is provided with a hanging hole 105. The lower end of the hanging hole 105 is provided with a slot 106 for accommodating the second support plate 2. Specifically, first fixing holes 108 for installing fixing pins are respectively provided on both sides of the first limiting boss 103. The hanging hole 105 is a waist hole.

[0034] See also Figure 5 As shown, the second support plate 2 includes a second body 201, and the two ends of the second body 201 are respectively provided with a second lifting hook hole 202, the middle part of the second body 201 protrudes upward to form a second limiting boss 203, and the bottom of the second body 201 is provided with a limiting groove 204 adapted to the slot 106. Specifically, the first body 101 is provided with a plurality of first process holes 107; the second body 201 is provided with a plurality of second process holes 205. The two ends of the first body 101 are respectively provided with a second fixing hole 109 for installing a fixing pin; the two ends of the second body 201 are respectively provided with a third fixing hole 206 for installing a fixing pin. A first bevel 110 is provided between the two ends of the first body 101 and the first limiting boss 103; a second bevel 207 is provided between the two ends of the second body 201 and the second limiting boss 203. The first lifting hook hole 102 and the second lifting hook hole 202 are both notched grooves.

[0035] See also Figure 6 As shown, the slot-type cross hanger also includes a fixed card plate 3, a through hole 31 is provided in the middle of the fixed card plate 3, and four notches 32 are provided around the through hole 31, and the first limiting boss 103 and the second limiting boss 203 are inserted into the corresponding notches 32. Specifically, the fixed card plate 3 is a square structure, and notches are provided at the top corners of the fixed card plate 3. A positioning hole 33 is provided on the fixed card plate 3.

[0036] The working principle of the utility model is:

[0037] Use the second support plate to be inserted vertically 90° into the middle slot hole of the first support plate, and make the limiting slot of the second support plate snap into the slot hole of the first support plate; install the fixed card plate, make the limiting boss snap into the slot of the fixed card plate, and after tightening, use the fixing pin to insert into the first fixing hole of the first support plate to play a safety limiting role.

[0038] During hoisting, the hook is inserted into the hoisting hole of the first support plate, and the heavy objects can be hung on the hoisting hook holes at both ends of the first support plate and the second support plate using a hoisting belt or a hoisting aid. The process hole between the first support plate and the second support plate can not only reduce weight, but also be used as a hoisting hole, which can be conveniently and quickly installed and disassembled according to actual conditions. With this slot-type cross hoisting structure, when hoisting, gravity will cause the grooves of the first support plate and the second support plate to self-lock. At the same time, the secondary safety limit of the fixed card plate is increased to increase the rigidity of the component connection, completing a stable and safe hoisting work.

[0039] See also Figure 7 As shown in the figure, after the lifting work is completed, the fixed card plate, the first support plate, and the second support plate can be quickly removed and stacked in parallel. The overlapping process holes on the sides are fixed with fixed pins to realize the storage of the slot-type cross spreader, which greatly improves the use efficiency and saves storage space. This new slot-type cross spreader improves the work efficiency of crane operations with simple and quick disassembly and installation, convenient transportation, adaptability to various working conditions and working range.

[0040] In the description of the specification, the description with reference to the terms "one embodiment", "preferably", "example", "specific example" or "some examples" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the utility model, and the schematic expressions of the above terms in this specification do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in any one or more embodiments or examples in a suitable manner.

[0041] Through the description of the above structure and principle, technicians in the relevant technical field should understand that the present invention is not limited to the above-mentioned specific implementation methods. Improvements and substitutions based on the present invention using the known technology in the field all fall within the protection scope of the present invention and should be defined by the claims.
