Description
Technical field
The invention belongs to piping lane construction auxiliary devices, and in particular to a kind of fluid pressure type piping lane anchorage core model inner circumferential fastener.
Background technique
Underground pipe gallery is used to be used to concentrate the public tunnel of the municipal pipelines such as laying water, electricity, gas, communication in Urban Underground,
Existing underground pipe gallery is typically all the square structure of a prefabricated both-side opening in advance, to scene cable wire connection receipts when laying
It tightly forms, anchor slot can be arranged in the limited length of cable wire at the dog-ear of prefabricated piping lane, be connected for cable wire and tighten, and receive
Tight process is usually to load onto external mold in the tail portion (or head) of cable wire, is equipped with core model in external mold, the interior snare of the core model exists
On cable wire, external mold is tightened with core model by internal taper face, is artificial percussion core model in the past to tighten, external force tightens angle when tapping
Not right, receipts are not tight, improve use hand-rail type stretcher later, and structure is complicated, and cable wire tail portion is easy slippage, are difficult stress, Gong Renlao
Fatigue resistance is big, two kinds of structures finally can all cause tighten effect it is bad, cause piping lane leak, sedimentation, increase maintenance cost and when
Between, it needs to improve.
Summary of the invention
To solve the above problems, structure is simple the invention discloses a kind of fluid pressure type piping lane anchorage core model inner circumferential fastener,
Easy to use laborsaving, tightening effect is good, securely and reliably.
In order to achieve the above objectives, technical scheme is as follows:
A kind of fluid pressure type piping lane anchorage core model inner circumferential fastener, including hydraulic tongs and tensioning head, the tensioning head includes bottom
Seat, jacking block and two briquettings, the jacking block are connected by the telescopic block of connector and hydraulic tongs, are " people " font above jacking block
Structure, two briquettings are with jacking block two sides are set on, and the rotary shaft below briquetting is connect with connector by rack gear, the briquetting
Top is equipped with groove.
As an improvement of the present invention, the jacking block height is lower than briquetting height.
As an improvement of the present invention, " people " character form structure angle above the jacking block is 40-120 °.
As an improvement of the present invention, the groove is U-type groove.
As an improvement of the present invention, the hydraulic tongs are equipped with adjustable valve.
As an improvement of the present invention, the hydraulic clamp handle is equipped with anti-slip layer.
The beneficial effects of the present invention are:
A kind of fluid pressure type piping lane anchorage core model inner circumferential fastener of the present invention, groove are caught in cable wire, open hydraulic tongs,
Core model is compressed toward both ends using briquetting, vertically firmly level is converted to and exerts oneself, structure is simple, easy to use laborsaving, tightening effect
Fruit is good, safe and reliable non-slip.
Detailed description of the invention

Specific embodiment
With reference to the accompanying drawings and detailed description, the present invention is furture elucidated, it should be understood that following specific embodiments are only
For illustrating the present invention rather than limiting the scope of the invention.It should be noted that word " preceding " used in the following description,
" rear ", "left", "right", "up" and "down" refer to that the direction in attached drawing, word "inner" and "outside" refer respectively to direction or remote
Direction from geometric center of specific component.
As shown, a kind of fluid pressure type piping lane anchorage core model inner circumferential fastener of the present invention, including hydraulic tongs 1 with
Tight head, the tensioning head include pedestal 2, jacking block 3 and two briquettings 4, and the jacking block 3 is stretched by connector 5 and hydraulic tongs
Contracting block 6 connects, and is " people " character form structure above jacking block 3, and two briquettings 4, which are matched, is set on 3 two sides of jacking block, the rotation of 4 lower section of briquetting
Shaft 7 is connect with connector 5 by rack gear, and groove 8 is equipped with above the briquetting 4.
As shown in figure 3, a kind of fluid pressure type piping lane anchorage core model inner circumferential fastener of the present invention, major function is by core
It is molded into external mold, core model is made to tighten cable wire 12, entire movement is completed in anchor slot 11, and groove 8 is caught in cable wire when work
12, hydraulic tongs 1 are opened, core model 14 is compressed toward both ends using briquetting 4, vertically firmly level is converted to and exerts oneself, structure is simple, makes
With convenient and strength-saving, tightening effect is good, and groove 8 is caught in cable wire 12, non-slip in compaction process, securely and reliably.
