Description

Double trolley combined type Electric Chain Blocks with locking device

【Technical field】

The utility model is related to a kind of double trolley combined type Electric Chain Blocks with locking device, the electronic calabashes of the loop chain Lu Zuowei lifts by crane the specific purpose tool of wind power plant, belongs to the locking fixture technical field of Electric Chain Blocks.

【Background technology】

Wind power plant needs to position trolley combined type Electric Chain Blocks in the set-up procedure of lifting, This will make trolley slide on track girder and be accurately fixed on a certain operation basic point of track girder after substantially in place, and small Vehicle is reliably fixed the screw rod for usually requiring to increase by two pieces of clamping plates of installation and connecting cleat on the basis of original track girder, then Trolley could be fixedly clamped on track girder by means of clamping plate and screw rod, there are following technical deficiencies for above-mentioned fixed structure：

Before hoisting heavy or when standing by, the fixed of trolley needs additional clamping plate and spiral shell on track girder Bar there are deficiency during installation fee, and needs to separate clamping plate and screw rod after hoisting heavy, trolley can slide against on track girder with Weight is transported, and exists and dismantles time-consuming deficiency.

【Utility model content】

The purpose of this utility model is to provide a kind of double trolley combined type Electric Chain Blocks with locking device, the lock Tight device can be locked fast locks with fast releasing.

For this purpose, the utility model adopts the following technical solution：

Double trolley combined type Electric Chain Blocks with locking device, including link, Electric Chain Blocks and two sets Carriage device, the link is parallel within the underface of track girder, and link its length in length direction and track girder Degree direction is consistent, and Electric Chain Blocks is fixed on the lower section of link by cucurbit bearing frame, and two sets of carriage devices pass through drop in beam It is individually fixed on link, and two sets of carriage devices are disposed on track girder, improvement is：It at least further includes a set of Locking device, locking device include one piece of rubber block, one piece of latch segment, a check lock lever and an extension bar, the check lock lever Be threadedly connected on the side end of link, and check lock lever its stretch out link upper end be fixedly connected with latch segment, check lock lever Lower end flexible connection extension bar, the top surface adhesive rubber block of latch segment, and rubber block is corresponding with the bottom surface of track girder, passes through Extension bar drives one direction rotation of check lock lever, rubber block top can be made real in the bottom surface of track girder, extension bar drives check lock lever court Another direction rotates, and rubber block then de-orbits the bottom surface of beam.

To further enhance locking effect, above-mentioned locking device has two sets, two check lock lever spiral shells of this two sleeve locking apparatus Line is connected in the both side ends of link, and the dormant state that so can preferably be locked double trolley combined type loop chain is electronic Cucurbit prevents the high-altitude vibration generated by wind power plant operation from leading to double trolley combined type Electric Chain Blocks in track girder It is upper slip and hit wind power generator cabin inner part.

The utility model has the following advantages that and good effect：

It has abandoned prior art clamping plate and screw rod is fixedly clamped structure, a side is pressed by the locking device of the utility model Then can be fast real in the bottom surface of track girder by rubber block top to rotation lock bar, it can so realize link, be fixed on connection It is lock onto on track girder together with trolley and the Electric Chain Blocks being fixed on link on frame, Electric Chain Blocks just can be fixed Position is in the operation basic point of needs, and check lock lever rotates to another way, may be such that rubber block moment de-orbits the bottom surface of beam, The releasing of locking is realized in the case of locking device free of demolition, carriage device just can restore sliding on track girder.

【Description of the drawings】

Fig. 1 is the structure diagram of the utility model；

Fig. 2 is double trolley and Electric Chain Blocks locking positioning in the structure diagram on track girder.

【Specific embodiment】

It please refers to Fig.1, shown in 2, the double trolley combined type Electric Chain Blocks with locking device, including link 2, ring Chain electric block 3, carriage device 11 and carriage device 12, link 2 are located at the underface of track girder G, link 2 and track girder G is mutually parallel, and direction is consistent, and Electric Chain Blocks 3 passes through calabash along stretching for link 2 its length in length direction and track girder G Reed bearing frame 4 is fixed on the lower section of link 2, and two sets of carriage devices are individually fixed in by drop in beam H on link 2, and two sets Carriage device is disposed on track girder G, and improvement is：A sleeve locking apparatus 5 is at least further included, locking device includes one 51, one pieces of the block rubber block check lock lever 53 of latch segment 52, one and an extension bar 54, check lock lever 53 are threadedly connected to link 2 Side end on, and check lock lever 53 its stretch out the upper end of link 2 and be fixedly connected with latch segment 52, the lower end of check lock lever 53 is movable Extension bar 54, the top surface adhesive rubber block 51 of latch segment 52 are connected, and rubber block 51 is corresponding with the bottom surface of track girder G, passes through Extension bar 54 drives the rotation of 53 clockwise direction of check lock lever, can push up rubber block 51 real in the bottom surface of track girder G, extension bar 54 drives Check lock lever 53 is rotated towards left hand direction, and rubber block 51 then de-orbits the bottom surface of beam G.

Link 2 is made of connection frame body and the L-type gusset being welded in connection frame body both ends of the surface.

Two sets of carriage devices are conventional structure and the two structure is identical, often cover carriage device and are consolidated respectively by a drop in beam H Due on link 2；Two sets of carriage devices often cover carriage device and are disposed in rail by wheel (not indicating) to slide serial verb construction On road beam G.

Embodiment as priority, locking device have two sets, and two check lock levers of this two sleeve locking apparatus are threadedly coupled In in the both side ends of link 2.

As shown in Fig. 2, two sleeve locking apparatus structures are identical generally applicable, per sleeve locking apparatus mainly by one piece of rubber block, one Block latch segment, a check lock lever and an extension bar composition.
