Description

Subway wheel pair hoisting sling

Technical Field

The utility model relates to a subway wheel is to processing technology field, in particular to subway wheel is to hoist and mount hoist.

Background

The wheel set needs to be hoisted in the machining process of the subway wheel set, the gravity center of the wheel set is not located in the middle position of the wheel set due to the fact that the weights of the two ends of the subway wheel set are different, and the two ends of the subway wheel set cannot be guaranteed to be in a horizontal state when a common lifting appliance is used for lifting, transferring and placing, so that the hoisting operation difficulty is high, and the safety risk is high.

SUMMERY OF THE UTILITY MODEL

The utility model discloses to the big, the big problem of safe risk of the operation degree of difficulty that exists at subway wheel pair hoist and mount in-process, provide a subway wheel to hoist and mount hoist, it is convenient to adjust to enable the subway wheel pair to keep horizontality, easy operation, safety at hoist and mount in-process.

In order to solve the technical problem, the utility model discloses a technical scheme as follows:

the utility model provides a subway wheel is to hoist and mount hoist, includes rings and hoist and mount chain, is located the rings inboard and is provided with the setting element, the setting element intermediate position is provided with the draw-in groove, the chain ring of hoist and mount chain can block and establish in the draw-in groove, and the chain ring that is located this chain ring both sides separates respectively and sets up in the setting element both sides.

In the above technical scheme, further, clearance fit is provided between the chain ring and the clamping groove.

In the above technical solution, further, the chain rings located at both sides of the positioning member are in clearance fit with the end faces at both sides of the positioning member.

In the above technical scheme, further, the link ring clamped in the clamping groove and the hanging ring are arranged perpendicular to each other, and the link ring is vertically arranged on a vertical central axis of the hanging ring.

In the above technical scheme, further, the locating piece includes two locating pieces that set up at the rings inboard relatively, be provided with certain interval between the locating piece.

In the above technical scheme, furthermore, lifting hooks are respectively arranged at two ends of the lifting chain.

In the technical scheme, furthermore, the two ends of the subway wheel set are respectively connected with a nylon hanging strip, and the lifting hooks are respectively connected with the nylon hanging strips.

The utility model discloses simple structure, operation, convenient to use can conveniently adjust the length of hoist and mount chain in hoist and mount both sides according to the focus place position of subway wheel pair, and the connection between hoist and mount chain and the rings is reliable and stable, can effectively guarantee the security of hoist and mount in-process.

Drawings

Fig. 1 is a schematic structural diagram of the present invention.

Fig. 2 is a schematic view of the connection structure of the middle positioning member and the hanging ring of the present invention.

In the figure: 100. the lifting ring comprises a lifting ring 200, a lifting chain 201, a chain ring 301, a positioning piece 302, a clamping groove 400 and a lifting hook.

Detailed Description

The invention will be further described with reference to the accompanying drawings and specific embodiments.

As shown in fig. 1 and 2, the hoisting tool for subway wheel set in this embodiment includes a hanging ring 100 and a hoisting chain 200, a positioning member is disposed inside the hanging ring, a slot 302 is disposed in the middle of the positioning member, a chain ring 201 of the hoisting chain can be clamped in the slot 302, and the chain rings 201 on two sides of the chain ring are separately disposed on two sides of the positioning member.

The positioning member in this embodiment includes two positioning pieces 301 relatively disposed on the inner side of the hanging ring, a certain distance is disposed between the positioning pieces 301, and the distance forms a slot structure disposed on the positioning member.

Preferably, the link 201 is in clearance fit with the slot 302; specifically, the link 201 clamped in the clamping groove is perpendicular to the hanging ring 100, and the link 201 is perpendicular to the vertical central axis of the hanging ring. That is, the diameter of the chain ring in the hoisting chain of the embodiment is matched with the size of the clamping groove, so that the chain ring can be just clamped between the two positioning pieces to limit the chain ring in the plane direction along the hanging ring.

Preferably, the chain rings 201 on both sides of the positioning piece are in clearance fit with the end surfaces on both sides of the positioning piece; the chain ring 201 of both sides butt respectively on the terminal surface of setting element both sides, and the chain ring to setting up in the draw-in groove of card is spacing along rings plane vertically direction to carry out fixed mounting to the chain ring on rings, prevent to cause the slip of hoist and mount chain in hoist and mount process because of subway wheel pair both sides weight is different, can make the adjustment of hoist and mount chain convenient simultaneously, guarantee the level of subway wheel pair and lift by crane.

The lifting hooks 400 are respectively provided at both ends of the lifting chain 200. The two ends of the subway wheel set are respectively connected with the nylon hanging strips, the lifting hooks 400 are respectively connected with the nylon hanging strips, the subway wheel set is conveniently lifted, and the surface of the wheel set can be prevented from being damaged in the lifting process.

The present invention is not limited to the above description and drawings, but should be understood as being illustrative and not restrictive, and the technical features can be replaced and modified without creative efforts by those skilled in the art according to the technical content disclosed, all falling within the scope of the present invention.
