Description
Technical field:
The utility model relates to a kind of adjusting device, is specifically related to a kind of stretching adjusting device.
Background technology:
Hoist cable is the rope that is used for lifting of making for raw material with steel wire rope or synthetic fiber etc.Be again span rope or jack line.Hoist cable mainly contains metal suspender and synthetic fiber hoist cable two large classes.And the metal hoist cable mainly contains: wire rope sling class, chain hoist cable class etc.The synthetic fiber hoist cable mainly contains: the rope class take polyamide fibre, polypropylene fibre, terylene, high-strength high-modulus polyethylene fiber as manufacture of materials and band class hoist cable.When selecting the hoist cable specification, must be size, weight, the profile of the load of being lifted by crane, and the occupation mode coefficient of the joint effects such as hanging method that prepare to adopt lists in to calculate and considers, the requirement of the maximal work power that provides, and the kind of working environment, load must take in simultaneously.Must select existing enough abilities, can satisfy again the hoist cable of the appropriate length of occupation mode, if a plurality of hoist cable is used simultaneously lifting loads, must select the same-type hoist cable; The raw material of flat hoist cable can not be subject to environment or load effect.No matter whether annex or soft hanger need, and must consider the latter end of hoist cable and auxiliary accessory and crane gear carefully and be complementary.
And general hoist cable tends to occur big and small problem in the process of using, these most of reasons all are because the misoperation in the middle of the process of producing, making, perhaps the quality of the product that causes of the reason such as aging of equipment can not get good assurance, because hoist cable generally all needs very firm, security performance will improve like this, when producing, just need to guarantee the fastness of hoist cable like this, not so can bring unnecessary danger.
The utility model content:
Technical problem to be solved in the utility model is to overcome existing technological deficiency a kind of a kind of stretching adjusting device rational in infrastructure, simple to operate, easy to use is provided.
Technical problem to be solved in the utility model adopts following technical scheme to realize:
A kind of stretching adjusting device, comprise bracing frame, support frame as described above is provided with fixed head, the support frame as described above upper end is provided with cylinder, it is characterized in that: described fixed head is semicircular structure, described fixed head is provided with swingle, be connected with link on the described swingle, described link is rectangle structure, described cylinder is connected to link one end, described link rotates along fixed head by the stretching of cylinder, on the described link transfer roller is installed, and support frame as described above, cylinder and link form triangular structure.
The beneficial effects of the utility model are: by the stretching of cylinder, bracing frame can rotate along fixed head by swingle, so just can drive rising or the reduction of the position of transfer roller, so just can play the fastening of hoist cable or the regulating action loosened.The utility model is rational in infrastructure, simple to operate, easy to use.
Description of drawings:
Fig. 1 is front view of the present utility model.
Fig. 2 is side view of the present utility model.
The specific embodiment:
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
Such as Fig. 1 and shown in Figure 2, a kind of stretching adjusting device comprises bracing frame 1, bracing frame 1 is provided with fixed head 2, bracing frame 1 upper end is provided with cylinder 3, and fixed head 2 is semicircular structure, and fixed head 2 is provided with swingle 4, be connected with link 5 on the swingle 4, link 5 is rectangle structure, and cylinder 3 is connected to link 5 one ends, and link 5 rotates along fixed head 2 by the stretching of cylinder 3, transfer roller 6 is installed on the link 5, and bracing frame 1, cylinder 3 and link 5 form triangular structure.
More than show and described basic principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
