Abstract
The utility model provides a traction device of a composite tube for crossing, mainly solving the problems in a crossing construction that tubular products are wasted and the construction efficiency is low resulted from high probability of separation between the conventional composite tube and a traction connector. The traction device is characterized in that a traction sleeve (1) is connected at the lower part of a traction plate (4), and is connected to a traction ferrule (2) via a plurality of connecting plates (3); and the inner diameter of the traction ferrule (2) can be regulated. The traction device provided by the utility model has the characteristics that no hole is needed to be drilled on the composite tube; the mounting, the assembly and disassembly are convenient; the tubular products are saved; and the construction efficiency is improved.
Description
Technical field
The utility model relates to a kind of traction gear that passes through with composite pipe, belongs to mechanical field.
Background technique
Present composite pipe earlier inserts a stopper in the composite pipe termination when crossing construction, punch inserting on the composite pipe termination tube wall of stopper then, with bolt stopper and composite pipe is fixed together, and the dilatory stopper enforcement of last tractor is passed through.This mode dilatory joint when crossing construction is made difficulty, constructing operation inconvenience, inefficiency; Long distance exists bolt hole to become big, bolt falling, the risk that causes tow attachment and composite pipe to break away from when passing through; Simultaneously, composite pipe termination punching section needs to downcut after passing through end, then again to the composite pipe end sealer; Cause the waste of tubing, and increased operation, reduced working efficiency.How economical with materials in crossing construction improves construction operation efficient, has become a user and producer guardian technique problem to be solved.
Summary of the invention
In order to overcome the deficiency that exists in the existing technology; The utility model provides a kind of traction gear that passes through with composite pipe; This traction gear that passes through with composite pipe has the advantages that to not be used in punching, easy installation and removal on the composite pipe, has practiced thrift tubing, has improved efficiency of construction.
The technological scheme of the utility model is: a kind of traction gear that passes through with composite pipe, comprise towing plate, and described towing plate bottom connects drag spring thimble, and described drag spring thimble connects the traction lasso through several connecting plates, and the internal diameter can regulate of traction lasso.
Described towing plate bottom connects the indirect towing plate that is cross, and towing plate is welded on the drag spring thimble indirectly.
Described traction lasso axially open, opening two ends weld parallel respectively and fixed plate axis, and can connect through bolt between the fixed plate, and described traction lasso top is welded with several gusset plates equably.
The utlity model has following beneficial effect: owing to take such scheme, this traction gear need not punch when crossing construction, has solved the problem of existing composite pipe punching section tubing waste; This apparatus structure is simple, and detachable between each parts, is convenient in the construction install and remove, and has improved working efficiency; Can avoid simultaneously in the construction distraction procedure, tow attachment is connected insecure with composite pipe and comes off.
Description of drawings:

Fig. 2 is the plan view of the utility model.
1-drag spring thimble among the figure, 2-draws lasso, 3-connecting plate, 4-towing plate, 5-clamping bolt, the indirect towing plate of 6-, 7-fixed plate, 8-gusset plate.
Embodiment:
Below in conjunction with accompanying drawing the utility model is described further:
Show that by Fig. 1 and Fig. 2 a kind of traction gear that passes through with composite pipe comprises towing plate 4; Described towing plate 4 bottoms connect drag spring thimble 1, and as preferably, described towing plate 4 bottoms can connect drag spring thimbles through indirect towing plate 6; Described indirect towing plate 6 is cross; Top is through dull and stereotyped connection reinforcing, and dull and stereotyped top is welded with towing plate 4, and the bottom of towing plate 6 is welded on the drag spring thimble 1 indirectly.Described drag spring thimble 1 connects traction lassos 2 through several connecting plates 3, and connecting plate 3 is with drag spring thimble 1 and draw between the lasso 2 and be connected through clamping bolt 5, makes for convenience detach.The internal diameter can regulate of described traction lasso 2, can realize in the following manner: described traction lasso 2 axially opens, opening two ends weld parallel respectively and fixed plate 7 axis; And can connect through bolt between the fixed plate 7; Like this, through adjusting two distances between the fixed plate 7, just can regulate the internal diameter of traction lasso 2; Thereby strengthen with composite pipe between be connected, avoid coming off.Described traction lasso 2 tops also can be welded with several gusset plates 8 equably, and traction lasso 2 is played the effect of gaining in strength.
When adopting the utility model to carry out crossing construction, at first weld a short tube in the composite pipe termination, electric smelting connects; To draw lasso 2 again and fix adjacent electric smelting place, then drag spring thimble 1 will be enclosed within an end of short tube, after putting in place in the termination of composite pipe; Use connecting plate 3 that drag spring thimble 1 and traction lasso 2 are linked together, fastening with clamping bolt 5, last; Through bearing pin the pull bar of tractor is connected with towing plate 4 and implements to pass through, passing through later, short tube can continue to be connected with other straight tube.
Claims (4)
1. traction gear that passes through with composite pipe; Comprise towing plate (4); It is characterized in that: described towing plate (4) bottom connects drag spring thimble (1); Described drag spring thimble (1) connects traction lasso (2) through several connecting plates (3), and the internal diameter can regulate of traction lasso (2).
2. the traction gear that passes through with composite pipe according to claim 1 is characterized in that: described towing plate (4) bottom connects the indirect towing plate (6) that is cross, and towing plate (6) is welded on the drag spring thimble (1) indirectly.
