The installation of solid blocks usually adopts the hoisting method, by setting a lifting point on the solid block, setting a hook under the lifting rope, and using the hook to hook the lifting point for lifting. After the solid block is hoisted to the preset position, it needs to be unhooked to carry out the hoisting of the next solid block. In this hoisting structure, the hook needs to be repeatedly hooked and unhooked, which is time-consuming and greatly affects the installation efficiency of the solid blocks. Utility Model Content

[0003] The invention object of the utility model is to provide a hoisting structure and a solid block hoisting system to solve the problems existing in the prior art, which can realize the rapid connection and separation of the solid block and the hoisting rope, thereby improving the efficiency.

[0049] A notch matched with the latch 10 may be provided on the suspended part, and the lifting rope 20 may be quickly connected to the suspended part by inserting the pin body 11 of the latch 10 into the notch.

[0050] The shapes of the suspended parts are various, such as square, spherical, cylindrical, etc.; the suspended parts can be solid structures or hollow structures.

[0068] Example 2

[0069] This embodiment provides a solid block lifting system, see Figure 3-8, including a solid block 30 and a lifting structure as described in Example 1, wherein: a first lifting groove 31 and a second lifting groove 32 are respectively provided on opposite sides of the solid block 30, the pin body 11 of the latch pin 10 is inserted into the first lifting groove 31 or the second lifting groove 32, and the connecting shaft 12 is located on the outside of the first lifting groove 31 or the second lifting groove 32.

[0070] The first lifting groove 31 and the second lifting groove 32 are both groove-shaped structures, including a groove body and at least one groove opening, and the pin body 11 of the latch pin 10 can be inserted into the groove body from the groove opening.

[0071] A latch 10 cooperates with a hanging slot.

[0072] The first hanging groove 31 and the second hanging groove 32 have a certain axial length to accommodate the pin body 11 of the plug pin 10 to prevent the plug pin 10 from being easily dislodged due to the insertion length being too short.

[0073] Preferably, the length of the pin body 11 is 1 / 4 to 1 / 2 of the length of the solid block 30 in the axial direction of the first hanging slot 31 or the second hanging slot 32 .

[0074] The cross-sectional shape of the first lifting groove 31 and the second lifting groove 32 can be various, such as circular, square, triangular, etc. Preferably, the cross-sectional shape of the groove body is the same as the cross-sectional shape of the pin body 11 .

[0075] The lifting rope 20 can be lifted by a lifting device, which may be a crane, a gantry crane, a tower crane, etc. The lifting device hooks the lifting rope 20 through a hook 22 .

[0076] The solid block 30 may be a concrete block or a natural stone or the like.

[0077] The solid block lifting system provided by the utility model can realize the rapid connection and separation between the lifting rope 20 and the solid block 30 by setting the first lifting groove 31 and the second lifting groove 32 and using the lifting structure as described above, thereby greatly shortening the lifting time of the solid block 30 and improving the lifting efficiency; the first lifting groove 31 and the second lifting groove 32 are located on the opposite sides of the solid block 30, so that the solid block 30 can be lifted from both sides, and the force is more reasonable.

[0078] Example 3

[0079] The solid block hoisting system provided in this embodiment is different from that in Embodiment 2 in that, in this embodiment, the axes of the first hoisting groove 31 and the second hoisting groove 32 are located on the same straight line.

[0080] The slots of the first hanging slot 31 and the second hanging slot 32 are respectively located on two opposite sides of the solid block 30 , and the slot bodies of the two are located between the two slots.

[0081] When a single hook 22 is used for lifting, the upper ends of all the lifting ropes 20 converge at one point, see Figure 8 , and the lower ends thereof are separated, and the lifting rope 20 can apply a component force to the latch 10 directed to the inside of the solid block 30, so that the plurality of latches 10 can clamp the solid block 30 from both sides, making it difficult for the latch 10 to fall out of the lifting groove, which is beneficial to the safety of lifting.

[0082] At the same time, being located on the same straight line can also avoid the torsion force that causes the solid block 30 to rotate, making the hoisting process more stable.

[0083] Preferably, the first hoisting groove 31 and the second hoisting groove 32 are connected.

[0084] In this embodiment, the first lifting groove 31 and the second lifting groove 32 are arranged in pairs, and one first lifting groove 31 is connected to one second lifting groove 32. The connected first lifting groove 31 and the second lifting groove 32 together form a through groove 33, and the through groove 33 has two openings, which are respectively located on the opposite sides of the solid block 30.

[0085] Connecting the first lifting groove 31 and the second lifting groove 32 can simplify the manufacturing process of the lifting groove, so that the first lifting groove 31 and the second lifting groove 32 that originally need to be opened separately can be opened at the same time, and can better ensure that the axes of the first lifting groove 31 and the second lifting groove 32 are located in the same straight line.

[0086] Preferably, the axes of all the first hoisting grooves 31 and the second hoisting grooves 32 are located on the same hoisting plane, and the hoisting plane is parallel to the bottom surface of the solid block 30 .

[0087] When the bottom surface of the solid block 30 is placed parallel or approximately parallel to the horizontal plane, the lifting plane is also parallel or approximately parallel to the horizontal plane, which can ensure the stable lifting and placement of the solid block 30, avoid large-angle flipping, and reduce the probability of accidents.

[0088] Example 4

[0089] The solid block lifting system provided in this embodiment is different from that in Embodiment 2 or 3 in that, in this embodiment, the number of the first lifting slots 31 and the number of the second lifting slots 32 are both two, and the number of the latches 10 is four.

[0090] The four latches 10 are respectively inserted into the two first hoisting slots 31 and the two second hoisting slots 32. The four latches 10 can be distributed in a matrix. The force transmission mechanism of this arrangement is more reasonable and can keep the posture of the solid block 30 stable during the hoisting process.

[0091] In this embodiment, both the first hanging groove 31 and the second hanging groove 32 are circular grooves, and PVC pipes are fitted on the inner circumferences of the first hanging groove 31 and the second hanging groove 32 .

[0092] The inner wall of the circular groove is an arc-shaped surface, and there is no protruding corner, so it is not easy to cause stress concentration and has good mechanical properties; the circular groove is simple to set up, which is convenient for unified specifications and standardized production.

[0093] Correspondingly, in this embodiment, the cross section of the pin body 11 is circular.

[0094] When the latch 10 is inserted into, withdrawn from or lifted from the solid block 30 , there is collision or friction between the latch body 11 and the hanging slot, which may easily cause damage to the latch 10 or the hanging slot. For this reason, a PVC pipe is provided for buffering.

[0095] The texture of the PVC pipe is relatively soft, and can protect the latch 10 and the hanging slot, thereby reducing the probability of damage to the latch 10 and the hanging slot.

[0096] Lifting method:

[0097] Before lifting, connect the lifting rope 20 to the lifting equipment, connect the lifting rope 20 to the pin 10, insert the pin body 11 of the pin 10 into the first lifting groove 31 and the second lifting groove 32, and the lifting equipment pulls the lifting rope 20 to lift the solid block 30 off the ground. After moving to a preset position, put down the solid block 30, and pull out the pin 10 to lift the next solid block 30.

[0098] Example 5

[0099] A solid block lifting system provided in this embodiment is different from that in Embodiment 2, 3 or 4 in that, in this embodiment, it also includes a box and a connecting pipe, the box and the connecting pipe are used for casting the solid block 30, the box has a casting cavity and an opening connected to the casting cavity, a first opening and a second opening are provided on the side wall of the box, the first opening and the second opening are respectively located on both sides of the box, and the connecting pipe passes through the first opening and the second opening in sequence.

[0100] The pouring cavity is used to contain concrete, and the opening may be located at the upper part of the box body.

[0101] The box body may include a bottom plate and side plates, and the bottom plate and the side plates may be fixedly connected or detachably connected, and the detachable connection facilitates the solid block 30 to be removed from the template.

[0102] The outer diameter of the connecting pipe is slightly smaller than the apertures of the first opening and the second opening, so that the connecting pipe can penetrate into the first opening and the second opening and prevent a large amount of slurry from flowing out during grouting.

[0103] By arranging the first opening and the second opening on the box body and using a connecting pipe to penetrate the first opening and the second opening in sequence, the first lifting groove 31 and the second lifting groove 32 can be naturally formed during the casting process of the solid block 30, without the need to drill or excavate the solid block 30 later, which can save the time for drilling or excavating the lifting grooves and will not cause structural damage to the solid block 30.

[0104] Preferably, the box body is made of steel, and the connecting pipe is a PVC pipe.
