Utility model content
The purpose of the utility model is to overcome prior art defect, a kind of diving propelling preventing free falling is provided and is filled
It sets.
The specific technical solution of the utility model is as follows:
A kind of diving propelling device preventing free falling a, comprising: derricking gear, a bracket and a diving propelling master
Machine, branch are set up in basin bottom to place diving propelling host, and derricking gear is latent set on hanging on the bank and by a wirerope
Water plug-flow host, above-mentioned bracket have a guide rod, and diving propelling host is along the guide rod upper and lower displacement, the tail end of diving propelling host
Equipped with an instantaneous safety tongs mechanism, which has a first state and one second state, when in the first shape
When state, which is not in contact with above-mentioned guide rod, and when in the second state, which holds tightly
Above-mentioned guide rod makes above-mentioned diving propelling host keep opposing stationary with above-mentioned guide rod.
In a preferred embodiment of the utility model, the instantaneous safe jaw mechanism includes a safe nesting, two
Wedge block and two wirerope fixed links, safety tongs set have with guide rod socket and a up-small and down-big sliding slot, this two
Wedge block adaptation is set to the two sides in the sliding slot and being set to the guide rod, and the front end of the wirerope fixed link is equipped with a counterweight
Block, rear end are pivotally connected the upper end of above-mentioned two wedge block respectively, and the wirerope is connected with the front of the wirerope fixed link.
It is further preferred that the clump weight is connected by an elastic component with the diving propelling host.
Still more preferably, the elastic component is spring.
It is further preferred that the front of the wirerope fixed link is equipped with several wirerope connecting holes.
The beneficial effects of the utility model are:
1, the diving propelling device of the utility model is equipped with instantaneous safety jaw mechanism, the case where wirerope is broken suddenly
Under, diving propelling host can be allowed to stop free falling rapidly, avoid casualties and equipment damage.
2, after the diving propelling host of the utility model drops to bracket, wirerope does not have pulling force, wirerope fixed link
It can also be pushed under the gravity of clump weight, instantaneous safety jaw mechanism is made to play fixed function, reduce diving propelling host
Vibration when operating normally.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the partial structure diagram of the instantaneous safe jaw mechanism in the utility model.
Specific embodiment
The technical solution of the utility model is further detailed below by way of specific embodiment combination attached drawing and
Description.
As shown in Figure 1, arrow is water (flow) direction, a kind of diving propelling device preventing free falling, including a lifting machine
Structure 1, a bracket 2 and a diving propelling host 3, bracket 2 are set to basin bottom to place diving propelling host 3, derricking gear 1
Diving propelling host 3 is hung set on the bank and by a wirerope 11.
Above-mentioned bracket 2 has a guide rod 21, diving propelling host 3 along 21 upper and lower displacement of guide rod, diving propelling host 3
Tail end is equipped with an instantaneous safety tongs mechanism 4, which has a first state and one second state, when being in
When first state, which is not in contact with above-mentioned guide rod 21, when in the second state, the instantaneous safety
Jaw mechanism 4 holds above-mentioned guide rod 21 tightly, and above-mentioned diving propelling host 3 is made to keep opposing stationary with above-mentioned guide rod 21.
As illustrated in fig. 1 and 2, the instantaneous safe jaw mechanism 4 includes a safe nesting 41, two wedge blocks 42 and two steel wires
Rope fixed link 43, which has and the guide rod 21 is socketed and a up-small and down-big sliding slot 410, two wedge block
42 adaptations are set to the two sides in the sliding slot 410 and being set to the guide rod 21, and the front end of the wirerope fixed link 43 is equipped with one and matches
Pouring weight, rear end are pivotally connected the upper end of above-mentioned two wedge block 42 respectively, the wirerope 11 with before the wirerope fixed link 43
Several wirerope connecting holes 430 in portion are connected.The clump weight 431 passes through a spring 432 and 3 phase of diving propelling host
Even.
Specifically, two wedge block 42 is not contacted with guide rod 21 when in normal lifting process, instantaneous safe jaw mechanism
4 do not influence the normal lifting of diving propelling host 3, that is, are in first state；In lifting process, as wirerope 11 is disconnected suddenly
It splits, wirerope fixed link 43 pulls down rapidly under the gravity of clump weight 431, drives two wedge blocks 42,410 phase along the chute
Safe nesting 41 is shifted up, and then contacts generation friction with guide rod 21, final guide rod 21 of holding tightly is to prevent diving propelling master
The decline of machine 3 is in the second state；It is lifted by crane again after more change steel rope 11, wirerope fixed link 43 pulls up, and drives two wedges
410 comparatively safe nestings 41 are detached to bottom offset with guide rod 21 shape sliding block 42 along the chute, i.e. recurrence first state, diving propelling
The elevating function back to normal of host 3.
Further, after diving propelling host 3 drops to bracket 2, wirerope 11 does not have pulling force, wirerope fixed link
43 push under the gravity of clump weight 431, so that instantaneous safety jaw mechanism is in the second state, play fixed function, subtract
Vibration of few diving propelling host 3 when operating normally.
The above, the only preferred embodiment of the utility model, therefore, it cannot be limited according to, and the utility model is implemented
Range, i.e., equivalent changes and modifications made according to the scope of the patent of the utility model and the content of the manual should still belong to practical
It is novel cover in the range of.
