Abstract

The utility model discloses an it covers structure of hoisting to keep warm to cheat, the motor end cap comprises a cover body, the lid is the quadrangle, the corner sets locking device of lid, 4 the one end of root chain is fixed on locking device, and one end is fixed on the flap seat in addition, the central authorities of flap seat set up the lug, locking device is including fixing the support frame on the lid, the support frame sets up the through -hole, and the screw rod passes the through -hole, the front end of screw rod sets up the link, the screw rod passes the both ends of through -hole department set up lock nut, still set up the balancing weight outside the lock nut of screw rod rear end, the balancing weight sets up the screw, the screw rod with the screw cooperation. The utility model has the advantages that: owing to adopted chain structure, consequently, can discover the defect as early as possible, because set up length adjustment device and configuration adjusting device, the production safety has been guaranteed to the balance that can guarantee to lift by crane the in -process lid.

Description

A kind of holding pit lid is sling structure

Technical field

This utility model relates to mechanical field, a kind of hoisting structure.

Background technology

Holding pit is that Special Steel Works steel foundry is according to steel manufacturing process requirement, the insulation built in casting production region Facility, the most multiple.Being incubated steel billet in a large number because having in hole, the steel material of allocation and transportation every day is big, and frequency is high, therefore wants its lifting Ask higher.

Existing structure is to use steel wire rope to be lifted by crane by lid, is only to tie up on lid by steel wire rope, lifts by crane with crane. It is thus impossible to ensure the balance of lid, and it is difficult to the crack conditions finding occur in steel wire rope, it is impossible to ensure safety in production.

Utility model content

For solving above-mentioned technical problem, the purpose of this utility model is to provide a kind of adjustable balance, and has compensation tune Joint function and the structure of slinging of configuration feature, concrete technical scheme is as follows:

A kind of holding pit lid is sling structure, including lid, it is characterised in that: described lid is tetragon, described lid Corner arranges locking device；One end of 4 chains is fixed on locking device, and other end is fixed on flap seat；In flap seat Centre arranges hanger；Described locking device includes the bracing frame being fixed on lid, and support frame as described above arranges through hole, and screw rod passes institute Stating through hole, the front end of screw rod arranges link；Screw rod arranges locking nut, at the lock of spiro rod rear end through the two ends of described through hole Also setting up balancing weight outside jack panel, described balancing weight arranges screw, and screw rod coordinates with described screw.

The utility model has the advantages that: owing to have employed chain structure, therefore, defect can be found as early as possible；Owing to being provided with Length adjustment device and configuration adjusting apparatus, it is ensured that the balance of lid during lifting, it is ensured that production safety.

Fig. 2 is the A direction view of Fig. 1；

Fig. 3 is the upward view of Fig. 1.

Detailed description of the invention

Illustrating this utility model below in conjunction with the accompanying drawings, as Figure 1-3, this utility model includes lid 1, described lid Body 1 is tetragon, and the corner of described lid 1 arranges locking device 2；One end of 4 chains 3 is fixed on locking device 2, additionally One end is fixed on flap seat 4；The central authorities of flap seat 4 arrange hanger 5；Described locking device 2 includes the bracing frame being fixed on lid 1 6, support frame as described above 6 arranges through hole, and screw rod 7 is through described through hole, and the front end of screw rod 7 arranges link 8；Described link 8 and chain 3 One end connect；Screw rod 7 arranges locking nut 9,10, outside the locking nut 10 of spiro rod rear end through the two ends of described through hole Side also sets up balancing weight 11, and described balancing weight 11 arranges screw, and screw rod 7 coordinates with described screw.

During use, owing to chain is to be socketed to form, due to unbalance stress by annulus one by one, it is impossible to 4 chains Length always consistent, for ensure lifting time lid constant with the angle of horizontal plane, a certain chain can be carried out by bolt The adjustment of bar length, it is also possible to be adjusted by balancing weight.

Claims

1. holding pit lid is sling a structure, including lid, it is characterised in that: described lid is tetragon, the four of described lid Angle arranges locking device；One end of 4 chains is fixed on locking device, and other end is fixed on flap seat；The central authorities of flap seat Hanger is set；Described locking device includes the bracing frame being fixed on lid, and support frame as described above arranges through hole, and screw rod is through described Through hole, the front end of screw rod arranges link；Screw rod arranges locking nut, in the locking of spiro rod rear end through the two ends of described through hole Also setting up balancing weight outside nut, described balancing weight arranges screw, and screw rod coordinates with described screw.
