Description
Technical field
The utility model is related to a kind of guard rail, more specifically to a kind of tunneling operation stand guard rail, category
In construction equipment technical field.
Background technology
Operation platform is essential in constructing tunnel, and operation platform is highly generally higher than 2m, therefore operation platform periphery
Safe protective railing need to be set.But, current existing traditional operation platform safe protective railing has the disadvantage that：1st, use
Steel pipe is directly welded on operation platform, non-dismountable, adds the space hold amount of stand；2nd, tunnel space is narrow and small, stand
Safe protective railing is easily damaged in lifting moving process；3rd, damage the dismounting of safety guide rail and reinstall needs largely
Time, delay the duration.
The content of the invention
The purpose of this utility model be for existing operation platform safe protective railing exist it is non-dismountable, delay
The problems such as duration, there is provided a kind of tunneling operation stand guard rail.
To achieve the above object, technical solution of the present utility model is：A kind of tunneling operation stand guard rail, bag
Sleeve base and column steel pipe are included, described sleeve base includes sleeve steel pipe and sleeve bottom steel plate, described sleeve steel pipe
Stand edge is welded in, described sleeve bottom steel plate is welded in sleeve steel pipe bottom, and described sleeve steel pipe side wall is provided with
Fastener, the trip bolt of the fastener runs through sleeve steel pipe side wall, and described column steel pipe is nested with sleeve steel pipe, phase
Protecting screen structure is provided between adjacent column steel pipe.
Described protecting screen structure includes hanging with protection between two horizontal bar bar steel pipes, two described horizontal bar bar steel pipes
Net, horizontal bar bar steel pipe two ends are vertically welded with end bends down, and two horizontal bar bar steel pipes of correspondence are on column steel pipe top with
The both sides at end are respectively welded joint steel pipe, and described joint steel pipe side wall is provided with fastener, and the trip bolt of fastener is passed through
Joint steel pipe side wall is worn, described end bends are inserted in corresponding joint steel pipe.
Circular hole is provided with the middle of described sleeve bottom steel plate.
Compared with prior art, the beneficial effects of the utility model are：
1st, make simple, material needed for the utility model is common materials in construction, it is easy to purchased.
2nd, installation, convenient disassembly, can be in the mobile preceding quick dismounting column of stand lifting, front rail and protection network, it is to avoid
This guard rail is destroyed in lifting moving process, after stand is in place, again can this good guard rail of Fast Installation, it is to avoid showed
With the presence of operation platform safe protective railing it is non-dismountable, delay the duration the shortcomings of and deficiency.
3rd, component is replaced easily, dismounting rear part takes up space small, is easy to carry, it is easy to management placement, it is not easy to lose.
4th, the sleeve base in the utility model is general in stand corner, end and middle part, and column steel pipe is in stand
Corner, end and middle part are general, and versatility is stronger.

Embodiment
The utility model is described in further detail below in conjunction with brief description of the drawings and embodiment.
Referring to Fig. 1 to Fig. 3, a kind of tunneling operation stand guard rail, including sleeve base and column steel pipe 3.Described
Sleeve base includes sleeve steel pipe 1 and sleeve bottom steel plate 2, and described sleeve steel pipe 1 is welded in stand edge, described sleeve
Bottom steel plate 2 is welded in the bottom of sleeve steel pipe 1；The described side wall of sleeve steel pipe 1 is provided with fastener 7, the fastener 7 it is tight
Gu screw runs through the side wall of sleeve steel pipe 1.The external diameter of column steel pipe 3 is slightly less than the internal diameter of sleeve steel pipe 1, and described column steel pipe 3 is nested with
In sleeve steel pipe 1, protecting screen structure is provided between adjacent upright posts steel pipe 3；After the insertion sleeve steel pipe 1 of column steel pipe 3, only need
Tighten the trip bolt, you can column steel pipe 3 is fixed in sleeve base.
Referring to Fig. 1, Fig. 4 to Fig. 7, described protecting screen structure includes two horizontal bar bar steel pipes 5, two described horizontal bar bars
Protection network 8 is hung between steel pipe 5；The two ends of horizontal bar bar steel pipe 5 are vertically welded with end bends 6 down.Two horizontal hand railing steels of correspondence
Pipe 5 is respectively welded joint steel pipe 4 in the both sides on the top of column steel pipe 3 and lower end, and the described side wall of joint steel pipe 4 is provided with tightly
Firmware 7；The trip bolt of fastener 7 runs through the side wall of joint steel pipe 4, and the external diameter of end bends 6 is slightly less than the internal diameter of joint steel pipe 4, institute
The end bends 6 stated are inserted in corresponding joint steel pipe 4；Tighten trip bolt, you can horizontal bar bar steel pipe 5 is fixed on connection steel
In pipe 4.Because horizontal bar bar steel pipe 5 can rotate around column steel pipe 3, operation platform platform corner position need not set special corner to stand
Post or Corner Link so that this guard rail is applicable in angle position at any angle.
Further, circular hole is provided with the middle of described sleeve bottom steel plate 2, prevents foreign matters from being blocked sleeve base.
Referring to Fig. 1, when this guard rail is installed, by sleeve base vertical welding on the same operation horizontal table top of stand, phase
Adjacent sleeve base spacing determines by the length of horizontal bar bar steel pipe 5, sleeve base, column steel pipe 3 and the installation of horizontal bar bar steel pipe 5
Afterwards, protection network 8 is hung, that is, completes the installation of this guard rail.
Above content is to combine specific preferred embodiment further detailed description of the utility model, it is impossible to
Assert that specific implementation of the present utility model is confined to these explanations.For the ordinary skill of the utility model art
For personnel, without departing from the concept of the premise utility, some simple deduction or replace, said structure can also be made
Protection domain of the present utility model should be all considered as belonging to.
