Description
Technical field
Hanging device is the utility model is related to, the manual chain block of equipment hoisting maintenance more particularly in pit-hole.
Background technology
Set in industries such as chemical industry, water process, dangerous waste processing, maintenances of equipment commonly using manual chain block lifting diving
It is standby, due to the limitation of chain block, need to be repeated several times manual hook in hoisting process, but in some Code in Hazardous Special Locations, such as
Strong acid, highly basic or containing heavy metal-polluted area of water treatment plant, easily allow sewage to stain equipment and human body during jack is linked up with,
Bring some unnecessary device damages, it is difficult to make operating personnel's direct skin contact sewage with avoiding, cause the chemistry of personnel
Injury.To solve practical problem present in above-mentioned place, a kind of R ＆ D design " type chain fast lock simple in construction is finally determined
Determine device ", its functional character designed is：Chain can be quickly locked, operating personnel need not directly connect in hoisting process
Touch the equipment surface of pollution.It thus can reduce to maximum program the risk that personnel and equipment are stain by sewage.
In pit-hole equipment hoisting upkeep operation be related in operation process pit-hole face, hoisting and hanging work, both belong to
Excessive risk homework type, especially in Industrial Waste Water Treatments factory, overhaul of the equipments is except including prison side and hoisting operation in pit-hole
Interior, maintainer is also possible to face highly corrosive chemical contact operation.Also, because the dirty chemical analysis of industry is complicated, pair set
Standby corrosivity is big, and plant life cycle is short in pit-hole in such a case, and failure-frequency is high, is thus brought to overhaul of the equipments personnel
The problem of be exactly that equipment replacement service work is frequent.At present in the fields such as chemical industry, water process, dangerous waste processing, maintenance of equipment often
Hoisting is as shown in Figure 1.
It is as follows to commonly use hoisting process idiographic flow in pit-hole at present as shown in Figure 1：
Work tool prepares：Lifting work start before, must complete figure it is shown in：Suspension bracket, chain block, cucurbit pull chain
Bar, gourd hook, equipment hoisting chain, the scene of jack hook prepare and installed.
Specific lifting step：
Step 1：Install suspension bracket 2；
Step 2：Hang up chain block 1；
Step 3：Gourd hook 4 is fixed on equipment hoisting chain 5；
Step 4：Operating personnel pull cucurbit to pull chain 3 and sling equipment in pit-hole 7；
Step 5：Equipment 7, because of chain block chain length deficiency, 8 is linked up with by chain block using jack during lifting
Jack is simultaneously linked up with again；
Step 6：Operating personnel, which pull on cucurbit and pull chain 3, slings equipment in pit-hole 7；
(if pit-hole depth is deeper, need to repeat the operation several times step 5, step 6)
Step 7：Equipment is hung out pit-hole, is placed on the ground, lifting is completed.
The defects of above-mentioned hoisting process understands to exist is to need to repeat step 5 and step 6 when pit-hole is deeper, cause
Lifting efficiency is low, while also in the presence of the equipment brought due to multiple jack is dropped, personnel injure by a crashing object, multiple directly contact arrangement table
The security risk that face is brought.
Utility model content
Studied and improved in consideration of it, the utility model provides one kind, there is provided a kind of chain fast self-locking device, it is pacified
On chain, fast self-locking and the unblock of chain are realized, it is safe to use, easy to operate, while equipment can be greatly enhanced and hung
The efficiency of dress.
In order to solve the above problems, the utility model uses following scheme：
A kind of chain fast self-locking device, including up/down perforation from lock box, the box chamber from lock box are provided with bullet
Property locking latch and for the elastic locking latch unblock unlocking structure, it is described that hook is installed from the top of lock box；Institute
Stating elastic locking latch includes being installed on being provided with locating piece from the latch in lock box box wall jack, the latch and being arranged with
Spring, it is inserted in by latch described in the elastic force of the spring in chain；The unlocking structure includes holding rod, the holding rod
End be inserted in it is described from the jack of lock box side wall.
It is of the present utility model to have technical effect that：
It is of the present utility model simple in construction, it is installed on cucurbit and pulls on chain, for the self-locking of chain, and unlocks operation
Simply, easy to use, reliability is high, and auxiliary cucurbit pulls chain and realizes efficient, safty hoisting operation.

Embodiment
Specific embodiment of the present utility model is described further below in conjunction with the accompanying drawings.
As shown in Fig. 2 the chain fast self-locking device of the present embodiment, including up/down perforation from lock box 9, from lock box 9
Elastic locking latch and the unlocking structure for the unblock of elastic locking latch are installed in box chamber, are provided with from the top of lock box 9
Hook 10；Elastic locking latch includes being installed on being provided with locating piece 12 from the latch 11 in the box wall jack of lock box 9, latch 11
And spring 13 is arranged with, it is inserted in by the resilient latches 11 of spring 13 in chain 5；Unlocking structure includes holding rod 14, holds
The end of bar 14 is inserted in from the jack of the side wall of lock box 9.
During use：The hook of chain block shown in Fig. 14 is arranged on shown in Fig. 2 at suspension ring 10, chain block is being pulled up
When, because the reaction force spring 13 installed at Bolt with latching action 11 shown in Fig. 2 plays self-locking action to equipment hoisting chain 5, make to set
Standby and whole self-locking device is together lifted, and when hanging certain altitude, equipment hoisting chain is tightened up and hangs over suspension bracket 2 shown in Fig. 1
On jack hook 8 on, at this moment can loosen chain block suspension hook, Bolt with latching action 11 shown in Fig. 2 can voluntarily pin equipment hang
Chain is filled, it will not be allowed to glide.If inserting the holding rod 14 shown in Fig. 2, holding rod 14 locks latch 11 in jack backward, from
Locking device can glide automatically.When pulling up cucurbit again, holding rod 14 is unclamped, self-locking device can implement self-locking to chain again,
So operating personnel can be not directly contacted with the equipment surface of pollution all the time in hoisting process, and equipment safety in pit-hole is hung
It is filled to ground.
