Description

Overhead hoist with barrier equipment above

Technical Field

The utility model relates to a lifting device matched with a crane for use, which is suitable for lifting equipment with an obstacle above and belongs to the technical field of lifting equipment.

Background

The crane refers to an electromechanical device for vertically lifting or vertically lifting and horizontally moving a heavy object, and most cranes, such as bridge cranes widely used in indoor and outdoor warehouses, factories, docks, and open storage yards, use steel wire ropes and hooks to hang the heavy object to be hoisted. The crane has the disadvantage that when an obstacle exists above the heavy object to be hoisted to influence the vertical lifting of the heavy object, great difficulty is caused in hoisting the heavy object. For example, in the daily production of the 1780 rolling line of the plate belt department of our factory, the balance blocks in the finish rolling region need to be periodically offline for maintenance, and due to the fact that obstacles exist above the balance blocks, a path for vertical lifting of the balance blocks does not exist, and the mass of the balance blocks is large, the balance blocks are extremely difficult to disassemble, and the working efficiency of equipment maintenance is greatly reduced. Therefore, it is necessary to design a lifting device capable of conveniently lifting equipment with obstacles above.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a lifting device with barrier equipment above aiming at the defects of the prior art so as to realize the quick lifting of the barrier equipment above and improve the maintenance efficiency of the equipment.

In order to achieve the purpose, the utility model adopts the following technical scheme:

the utility model provides a overhead hoist that barrier equipment has in top, includes crossbeam, balancing weight and wire rope in the constitution, the balancing weight is fixed to the one end of crossbeam, and the other end lower part is fixed with lower lug, the heavy object that needs hoist and mount is hung to the lower part of lug down, and the upper surface of crossbeam is fixed with two and goes up the lug, wire rope's middle part is hung on the lifting hook of hoist, both ends respectively with two last lug fixed connection.

The lifting device is provided with barrier equipment above, the cross beam is made of H-shaped steel, a web plate in the middle of the H-shaped steel is vertical to the horizontal plane, and an upper lifting lug and a lower lifting lug are respectively arranged on the web plates on two sides of the H-shaped steel.

The upper part of the lifting device is provided with the obstacle equipment, and the two upper lifting lugs are arranged along the length direction of the cross beam and are respectively fixed on two sides of the midpoint of the cross beam.

The upper lifting lug and the lower lifting lug are both semicircular plates, straight edges of the upper lifting lug and the lower lifting lug are fixedly connected with the cross beam, and a steel wire rope hole is formed in the middle of the upper lifting lug and the lower lifting lug.

The upper part of the lifting device is provided with obstacle equipment, and the balancing weight is connected with the cross beam through a bolt.

According to the utility model, the middle part of the cross beam is connected with the lifting hook of the crane through the steel wire rope, one end of the cross beam extends into the lower part of the barrier to be connected with the heavy object, the other end of the cross beam is fixed with the balancing weight, the heavy object is moved out from the lower part of the barrier through the transverse movement of the lifting device, and the steel wire rope and the cross beam cannot interfere with the barrier in the lifting process, so that the rapid lifting of the equipment with the barrier above is realized, and the maintenance efficiency of the equipment is improved.

In addition, the utility model has the advantages of simple structure, convenient operation, economy, practicality, wide application range, easy manufacture and the like, and is suitable for hoisting equipment in various limited spaces.

Drawings

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

FIG. 1 is a schematic structural view of the present invention;

fig. 2 is a schematic representation of the use of the present invention.

The reference numbers in the figures are as follows: 1. crossbeam, 2, last lug, 3, wire rope, 4, balancing weight, 5, lower lug, 6, heavy object.

Detailed Description

Referring to fig. 1, the utility model mainly comprises a beam 1, an upper lifting lug 2, a steel wire rope 3, a balancing weight 4 and a lower lifting lug 5. The beam 1 is made of H-shaped steel, the beam 1 can be made of Q235H-shaped steel with the model of HW300 multiplied by 300mm according to the space and the weight of equipment to be hoisted, the length of the H-shaped steel is 6000mm (how long the beam is according to the actual space), the thickness of a web plate in the middle of the H-shaped steel is 15mm, and the thickness of wing plates on two sides of the H-shaped steel is 15 mm.

The balancing weight 4 adopts weight to be 10 t's ordinary steel block (45 # steel), and steel block and main part adopt bolt and nut to be connected with crossbeam 1, have four phi 30 mm's bolt hole on the steel block for connect H shaped steel. The bolt and the nut of M30 × 350 are used in a matched mode, the bolt penetrates through the bolt holes in the steel block and the H-shaped steel and then is screwed into the nut, and the balancing weight and the H-shaped steel are fixed.

The beam 1 is connected with the heavy object 6 and the crane hook by three lifting lugs (two upper lifting lugs 2 and one lower lifting lug 5), each lifting lug is a semicircular iron plate with the diameter of 150mm, a steel wire rope hole with the diameter of 5mm is arranged in the middle of each lifting lug, and the three lifting lugs are fixed on the H-shaped steel in a welding mode.

When a heavy object with an obstacle above the heavy object needs to be hoisted, a steel wire rope 3 is adopted to connect a crane (crown block) lifting hook with two upper lifting lugs 2 on the beam 1, and the angle of the crane (crown block) lifting hook is controlled by adjusting the length of the steel wire rope 3, so that the equipment reaches a stable state. Then, the lifting end of the beam 1 (i.e. the end provided with the lower lifting lug 5) is extended into the lower space of the obstacle, the lower lifting lug 5 is connected with the heavy object by using a steel wire rope, and the heavy object 6 is lifted by hoisting by a crane (overhead crane) and is moved out of the obstacle.
