Description

Technical Field

[0001] This utility model relates to the field of casting auxiliary equipment, and in particular to a casting hoisting device. Background Technology

[0002] Lifting is a construction operation that uses lifting equipment to lift, move, and precisely install heavy or large castings into place. Currently, a chain connected by ring buckles is used as a connecting tool to connect the crane output end and the casting.

[0003] Since multiple chains originate from the same output end, an angle will appear between the chains after they are connected and hung at the hanging point. This angle will reduce the movement area of ​​the suspended casting. Therefore, multiple chains are connected with an external support. Taking a square casting as an example, its connecting end is equipped with a hanging lug. During hoisting, the chains are supported by the external support, so that the cooperating chains form a parallel structure in a local area to increase the movement space. When the hanging lug is attached to the chain, the casting can be flipped or have a cooperating casting added within the increased movement space.

[0004] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0020] See Figure 1 This utility model provides a casting hoisting device, which includes: At least two chains 1, the upper ends of which are connected to the output end of the crane and extend downward; the output end of the crane is generally a barb, and the upper ends of the chains 1 are wound around and locked onto the barb.

[0021] The support rod 2 is detachably connected at both ends to two chains 1 groups, each chain 1 group consisting of at least one chain 1; the connected support rod 2 creates a partially parallel movable area between the connected chain 1 groups, as shown in the figure. When in a supported state, the support rod 2 is horizontally set, and the lower part of the support rod 2 and the chain 1 it supports form a square space; the detachable connection between the support rod 2 and the chain 1 is that the end of the support rod 2 is provided with a fork 5, which is inserted into the hole of the chain 1.

[0022] The casting has a lug 4 at its end and the lower end of the chain 1 has a connection end to the lug 4. Generally, the connection end is part of the chain 1, that is, both ends of the chain 1 are connected to the barb, the middle area hangs down to form an installation area, and the lug 4 is fitted into the installation area.

[0023] During operation, firstly, connect the end of the support rod 2 to the chain 1, that is, the fork head 5 passes through the chain 1 at the connection position to provide external support for the chain 1. Then, hang the casting on the chain 1.

[0024] Two auxiliary support rods 3 are rotatably mounted on the middle of the support rod 2, and each auxiliary support rod 3 is mounted on the support rod 2 with resistance. The auxiliary support rods 3 have an external support state ( Figure 2 (As shown); in this state, the working end of the auxiliary support rod 3 extends beyond the detachable connection end of the support rod 2, pressing the chain 1 to expand the working area. In this state, the external support of the working area facilitates the insertion of additional castings.

[0025] See Figure 3 and Figure 5 The auxiliary support rod 3 has an inward support state; in this state, the working ends of the auxiliary support rod 3 are close to each other to form a buffer zone that can contact the casting. In this state, if the casting is flipped, the lug 4 in the longitudinal position ( Figure 4 (As shown) It will enter the buffer area and contact the auxiliary support rod 3. The auxiliary support rod 3 blocks the moving lug 4, and uses the rotational resistance of the auxiliary support rod 2 to reduce the overturning force of the casting, thereby increasing the safety of the operator.

[0026] Each auxiliary support rod 3 is hinged to the support rod 2, and its output end swings along the axis of the support rod 2. The resistance connection between the support rod 2 and the auxiliary support rod 3 is that the auxiliary support rod 3 has a pressing wall 8 that fits against the outer wall of the support rod 2, and the friction between the components provides resistance when the auxiliary support rod 3 rotates. A pressing assembly is also provided between the auxiliary support rod 3 and the support rod 2 to press the two walls together. The pressing assembly includes a pressing bolt 7 that passes through the pressing wall 8 and an arc-shaped guide groove provided on the support rod 2 for the pressing bolt 7 to pass through.

[0027] Preferably, a pressure plate 6 is detachably installed at the working end of the auxiliary support rod 3; the extension direction of the pressure plate 6 is perpendicular to the extension direction of the auxiliary support rod 3. The pressure plate 6 increases the contact area between the working end of the auxiliary support rod 3 and the chain 1, thereby improving the stability of the chain 1 in its external support state.

[0028] In summary, at least two chains are connected at their upper ends to the output end of the crane and extend downwards. The output end of the crane is generally a barb, and the upper ends of the chains are wound around and locked onto the barb. A support rod is detachably connected at both ends to two chain groups, each chain group consisting of at least one chain. The connected support rod creates a partially parallel movable area between the connected chain groups. The support rod is horizontally positioned in its supported state, and its lower portion forms a square space with the chain it supports. The detachable connection between the support rod and the chain is achieved by providing a fork at the end of the support rod, which inserts into a hole in the chain. The casting has lugs at its end, and the lower end of the chain has a connection point to the lug. Generally, this connection point is part of the chain, meaning both ends of the chain are connected to the barb, and the middle area droops down to form an installation area, where the lug fits. During operation, firstly, the end of the support rod is connected to the chain, that is, the fork head passes through the chain at the connection point to provide external support for the chain. Then, the casting is hung onto the chain. Two auxiliary support rods are rotatably mounted in the middle of the support rod, each auxiliary support rod being installed with resistance on the support rod. The auxiliary support rods have an external support state; in this state, the working end of the auxiliary support rod extends beyond the detachable connection end of the support rod, pressing the chain to expand the working area. In this state, because external support is achieved for the working area, it is convenient to insert additional castings. This utility model can set auxiliary support rods on the support rod and can switch between external and internal support states according to the needs of casting operation, ensuring work requirements and optimizing operation steps.

[0029] Of course, there may be other embodiments of this utility model. Without departing from the spirit and essence of this utility model, those skilled in the art can make various corresponding changes and modifications based on this utility model, but these corresponding changes and modifications should all fall within the protection scope of the appended claims of this utility model.
