Description

Technical Field

[0001] This utility model relates to the technical field of elevator testing equipment, specifically to a broken rope testing device for tower crane elevator testing. Background Technology

[0002] Tower cranes, which are devices used for the vertical transport of personnel, are designed with rope breakage protection structures for safety reasons. Therefore, rope breakage tests are required to test the reliability of the equipment above and the protection structure. However, since the steel wire rope needs to be broken instantly, the existing design uses a detachable buckle that is triggered by a long rod, such as the one published in CN210719644U. However, the stability of the equipment itself is difficult to control after the rope breaks. Moreover, at the moment of release, the steel wire rope is in an unrestrained state and is prone to violent rebound or swinging, which may damage surrounding equipment or cause danger to surrounding personnel. Utility Model Content

[0003] The purpose of this utility model is to provide a reasonably designed rope breakage testing device for tower crane hoisting, which can solve the above-mentioned defects and deficiencies of the existing technology.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: it includes an upper connector and a lower connector. The upper connector includes an upper hanging ring at the top, and the lower connector includes a lower hanging ring at the bottom. Both hanging rings are used to connect the test wire rope. The lower connector includes a connecting seat on which two movable buckles are rotatably mounted. The movable buckles are used to connect with the upper connector and can be disconnected during testing.

[0005] Preferably, a locking block is connected below the upper hanging ring, and the locking block has a conical structure.

[0006] Preferably, the movable buckle is a plate-shaped structure with a slot on its inner side that matches the shape of the card block. After the two movable buckles are rotated to fit together, the card block is locked in the slot.

[0007] Preferably, one of the movable buckles is provided with an electromagnet on the top outer side, and the other movable buckle is provided with an adsorption block on the top outer side. When the two movable buckles are attached, the electromagnet and the adsorption block are facing each other.

[0008] Preferably, the movable buckles are all rotatably mounted on the connecting seat via rotating shafts, with the rotating shafts located outside the movable buckles, and multiple limiting blocks are provided on both sides of the connecting seat.

[0009] Preferably, both the upper and lower connectors are provided with flexible anti-collision blocks at their corners.

[0010] The beneficial effects of this utility model after adopting the above structure are:

[0011] 1. This application uses electromagnet control, which eliminates the need for other complex moving parts. The structure is simple, and the conical block is connected by a movable buckle. The inclined connection method allows part of the gravity to be applied directly to the block. The attraction force required by the electromagnet is lower than the gravity supported below, resulting in lower power consumption.

[0012] 2. This application uses electromagnet control, which can control the connection or disconnection of the connector by switching the power on and off of the electromagnet, without the need for personnel to operate nearby, thus improving safety. On the other hand, when the upper steel wire rope is connected to the connector, compared with the unloaded steel wire rope, the angle at which the steel wire rope flies up will be greatly reduced at the moment of rope breakage test, thus reducing the damage to surrounding objects.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] See Figure 1 - Figure 5As shown, it includes an upper connector 2 and a lower connector 1. The upper connector 2 includes an upper hanging ring 201 at the top, and the lower connector 1 includes a lower hanging ring 102 at the bottom. Both hanging rings are used to connect the steel wire rope for testing. The lower connector 1 includes a connecting seat 101 on which two movable buckles 103 are rotatably mounted. The movable buckles 103 are used to connect with the upper connector 2 and can be disconnected during testing.

[0022] The upper hanging ring 201 is connected to a locking block 202 below. The locking block 202 has a conical structure, and the movable buckle 103 has a plate-like structure. The inner side of the buckle 103 has a slot 105 that fits the shape of the locking block 202. After the two movable buckles 103 are rotated to fit together, the locking block 202 is locked in the slot.

[0023] One movable buckle 103 has an electromagnet 106 on its outer top and an adsorption block 107 on its outer top. When the two movable buckles 103 are in contact, the electromagnet 106 and the adsorption block 107 are facing each other. The connecting seat 101 has a buckle 108 on its side, which is used to limit the power supply line of the electromagnet 106. The movable buckles 103 are all rotatably mounted on the connecting seat 101 via a rotating shaft 104. The rotating shaft 104 is located on the outside of the movable buckle 103. Multiple limiting blocks 109 are provided on both sides of the connecting seat 101. Flexible anti-collision blocks 3 are provided at the corners of the upper connector 2 and the lower connector 1.

[0024] During the test, the steel cable at the top of the car is connected to the lower hanging ring 102, and the steel cable of the upper elevator is connected to the upper hanging ring 201. When the electromagnet 106 is not energized, the two movable buckles 103 are separated. When they are closed, the electromagnet 106 is energized and can magnetically attract the adsorption block 107, thus tightening the two movable buckles 103. Therefore, before the test, the locking block 202 is aligned and placed into the locking slot 105. After closing the two movable buckles 103, the electromagnet 106 is energized, and the upper connector 2 and lower connector 1 are connected as one unit to facilitate the car lifting. During the test, the power supply to the electromagnet 106 is disconnected. Without the magnetic force, under the action of gravity, the locking slot 105 slides outward along the locking block 202. Figure 5 As shown, the two movable buckles 103 separate, and the upper connector 2 and the lower connector 1 are disconnected. Since the disconnection is controlled by the power switch of the electromagnet 106, no personnel are needed to operate nearby. Furthermore, the upper connector 2 is connected to the wire rope and has its own weight. Therefore, the amplitude of the wire rope flying after disconnection is greatly reduced compared to the empty wire rope, thus greatly improving safety during the test.

[0025] The installation, connection, or setting methods of the components not detailed above are all common mechanical methods, and the specific structure, model, and coefficient indicators of all their components are their own technologies. As long as they can achieve their beneficial effects, they can be implemented, so they will not be elaborated further.

[0026] It should be understood that the above-described specific embodiments of this utility model are merely illustrative or explanatory of the principles of this utility model and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of this utility model should be included within the protection scope of this utility model. Furthermore, the appended claims are intended to cover all variations and modifications falling within the scope and boundaries of the appended claims, or equivalent forms of such scope and boundaries.
