Abstract
The utility model relates to the technical field of jack, especially a kind of Novel road bridge steel strand tension jack, there is the bellows connected successively from left to right, left work anchor ring, operative body and right work anchor ring, spacing ring is provided with between described left work anchor ring and operative body, spacer shell is provided with between described operative body and right work anchor ring, be provided with multiple left work clip sheet between described left work anchor ring and spacing ring, between described right work anchor ring and spacer shell, be provided with multiple right work clip sheet.This Novel road bridge steel strand tension jack, simple structure, stretch-draw work efficiency and backhaul work efficiency all very high.
Description
Technical field
The utility model relates to the technical field of jack, especially a kind of Novel road bridge steel strand tension jack.
Background technology
Jack is divided into mechanical jack and hydraulic jack two kinds, wherein, the liquid pressure everywhere of hydraulic jack is consistent, like this, in the system of balance, above smaller piston, applied pressure is smaller, and applied pressure is also larger on large piston, the static of liquid can be kept like this, by the transmission of liquid, the different pressure on different end can be obtained, so just can reach the object of a conversion.
Mechanical jack adopts theory of machines, back and forth to pull handle, namely pusher dog promotes the revolution of ratchet gap, bevel pinion drives large bevel gear, weight lifting screw rod is rotated, thus make jacking sleeve acquisition hoist or decline, and reach the function of lifting pulling force, but mechanical jack is simple and easy not as hydraulic jack.
Utility model content
The technical problems to be solved in the utility model is: in order to solve the prior art Problems existing in above-mentioned background technology, a kind of Novel road bridge steel strand tension jack of improvement is provided, simple structure, stretch-draw work efficiency and backhaul work efficiency all very high.
The utility model solves the technical scheme that its technical matters adopts: a kind of Novel road bridge steel strand tension jack, there is the bellows connected successively from left to right, left work anchor ring, operative body and right work anchor ring, spacing ring is provided with between described left work anchor ring and operative body, spacer shell is provided with between described operative body and right work anchor ring, be provided with multiple left work clip sheet between described left work anchor ring and spacing ring, between described right work anchor ring and spacer shell, be provided with multiple right work clip sheet.
In order to improve the structural strength of bellows, therefore the outer tube wall of described bellows is evenly provided with multiple spiral reinforcing rod outward.
In order to accelerate stretch-draw work and the backhaul work of jack, therefore the outer wall of described operative body is symmetrically arranged with two stretch-draw hydraulic fluid ports and two backhaul hydraulic fluid ports up and down.
In order to ensure the normal work of jack, therefore described left work clip sheet is identical with the quantity of right work clip sheet, and position is corresponding.
Further specifically, on the left of described bellows, the diameter dimension of opening is less than the diameter dimension of right openings.
The beneficial effects of the utility model are: Novel road bridge steel strand tension jack of the present utility model, and structure is simple, and reasonable in design, structural strength is high, easy to maintenance, stretch-draw work efficiency and backhaul work efficiency all very high, economic utilization rate is higher.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
Label in accompanying drawing is: 1, bellows, 2, left work anchor ring, 3, operative body, 4, right work anchor ring, 5, spacing ring, 6, spacer shell, 7, left work clip sheet, 8, right work clip sheet, 9, spiral reinforcing rod, 10, stretch-draw hydraulic fluid port, 11, backhaul hydraulic fluid port.
Detailed description of the invention
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present utility model are described in a schematic way, and therefore it only shows the formation relevant with the utility model.
As shown in Figure 1, a kind of Novel road bridge steel strand tension jack, there is the bellows 1 connected successively from left to right, left work anchor ring 2, operative body 3 and right work anchor ring 4, spacing ring 5 is provided with between described left work anchor ring 2 and operative body 3, spacer shell 6 is provided with between described operative body 3 and right work anchor ring 4, be provided with multiple left work clip sheet 7 between described left work anchor ring 2 and spacing ring 5, between described right work anchor ring 4 and spacer shell 6, be provided with multiple right work clip sheet 8.
Wherein, the outer tube wall of described bellows 1 is evenly provided with multiple spiral reinforcing rod 9 outward.The outer wall of described operative body 3 is symmetrically arranged with two stretch-draw hydraulic fluid ports 10 and two backhaul hydraulic fluid ports 11 up and down.Described left work clip sheet 7 is identical with the quantity of right work clip sheet 8, and position is corresponding.The quantity of left work clip sheet 7 and right work clip sheet 8 is three, and the quantity of spiral reinforcing rod 9 is three, and two stretch-draw hydraulic fluid ports 10 are all positioned at the left side of two backhaul hydraulic fluid ports 11.The cross sectional shape of spacing ring 5 is spill.On the left of bellows 1, the diameter dimension of opening is less than the diameter dimension of right openings.
With above-mentioned according to desirable embodiment of the present utility model for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this utility model technological thought, can carry out various change and amendment completely.The technical scope of this utility model is not limited to the content on specification sheets, must determine its technical scope according to right.
