Abstract
The utility model is related to a kind of tunnel escape tube rock-fall impact experimental provisions, including Hanging Basket, Hanging Basket upper end opening, both sides are fixedly mounted with handle, Hanging Basket surrounding side wall is set for fence item, stone, which is formed with, among Hanging Basket bottom surface grows mouth, grow the two of mouth to two switch gates to sidewall symmetry hinge dress in stone, grow a mouthful both sides one extension to stone and be formed with fixture block in the both sides of the edge of switch gate, two fixture block ends are slidably installed a pressure pin, drawbar blocks fixture block, switch gate is closed in realization, four motors are installed in the corresponding Hanging Basket bottom surface side of pressure pin, motor piston rod end is coaxially fixedly mounted with bevel gear, bevel gear is intermeshed with pressure pin, realize the movement of pressure pin.The opening of escape tube rock-fall impact experimental provision in tunnel provided by the utility model is two openings that can be opened moment, can simulate impact of the falling rocks moment to pipeline, improves the authenticity of pipe detection data.
Description
Technical field
The utility model belongs to protection field more particularly to a kind of tunnel escape tube rock-fall impact experimental provision.
Background technology
The tunnel in tunnel and mine in the construction process, due to being influenced by complicated geology and other factors, happens occasionally
Landslide phenomenon, wherein landslide phenomenon consequence of closing the door is the most serious, once the life for occurring to seriously affect in-cavity construction personnel is pacified
Entirely.Therefore, for the phenomenon of caving in tunnel, constructing tunnel, to avoid personnel casualty accidents as far as possible, unnecessary warp is reduced
Ji loss, carries out the setting of tunnel pipe for escaping, it appears extremely important.
Utility model content
The purpose of the utility model is to overcome in place of the deficiencies in the prior art, provide a kind of structure novel, test kind
More tunnel escape tube rock-fall impact experimental provisions.
The technical scheme adopted by the utility model is that：
A kind of tunnel escape tube rock-fall impact experimental provision, including Hanging Basket, Hanging Basket upper end opening, both sides are fixedly mounted with handle, hang
Basket surrounding side wall is set for fence item, it is characterised in that：Stone is formed among Hanging Basket bottom surface and grows mouth, grows mouth in stone
Two grow a mouthful both sides one extension to stone and are formed with card to two switch gates to sidewall symmetry hinge dress, the both sides of the edge of switch gate
Block, two fixture block ends are slidably installed a pressure pin, and fixture block is blocked, realizes and close switch gate by drawbar, in the corresponding extension of pressure pin
Basket bottom surface side is equipped with four motors, and motor piston rod end is coaxially fixedly mounted with bevel gear, and bevel gear is intermeshed with pressure pin, real
The movement of existing pressure pin.
Moreover, four pulleys are filled convenient for symmetrical hinge in Hanging Basket surrounding sidewall bottom.
The advantages of the utility model and good effect are：
There are one larger Hanging Baskets for tunnel escape tube rock-fall impact experimental provision provided by the utility model, and the inside can contain
Put the stone of variously-shaped and size, weight, be capable of the scene of real simulation Tunnel Landslide, detect pipeline it is pressure-resistant, resistance to pound with
And recovery capacity, ensure the authenticity and accuracy of testing result.
What the opening of escape tube rock-fall impact experimental provision in tunnel provided by the utility model can be opened moment for two
Opening can simulate impact of the falling rocks moment to pipeline, improve the authenticity of pipe detection data.
Description of the drawings
Fig. 1 is the structure diagram of the utility model.
The bottom view of Fig. 2 and Fig. 1.
Specific embodiment
With reference to embodiment, following embodiments, which are illustrative, are not limited is further illustrated to the utility model
, it is impossible to limit the scope of protection of the utility model with following embodiments.
A kind of tunnel escape tube rock-fall impact experimental provision, including Hanging Basket 1, Hanging Basket upper end opening, both sides are fixedly mounted with handle 2,
Hanging Basket surrounding side wall is set for fence item, can effectively place irregular stone etc., being formed with stone among Hanging Basket bottom surface grows
Mouthfuls 9, grow the two of mouth to two switch gates 8 to sidewall symmetry hinge dress in stone, the both sides of the edge of switch gate are grown to stone
Integrally extension is formed with fixture block 7 for mouthful both sides, and two fixture block ends are slidably installed a pressure pin 6, and drawbar blocks fixture block, and realizing will switch
Door is closed, and four motors 4 are equipped in the corresponding Hanging Basket bottom surface side of pressure pin, and motor piston rod end is coaxially fixedly mounted with bevel gear 5,
Bevel gear is intermeshed with pressure pin, realizes the movement of pressure pin, folding switch gate.
For the ease of movable hanging basket, four pulleys 3 are filled convenient for symmetrical hinge in Hanging Basket surrounding sidewall bottom, for quickly moving
Hanging Basket.
The working method of the utility model is as follows：
Switch gate to be closed, pressure pin is mobile to centre, holds card soon, stone is placed inside Hanging Basket, and size shape differs,
The handle of Hanging Basket both sides is lifted with crane, mentions certain altitude, such as 20 meters, is then turned on motor, moment opens two and opens
It closes the door, stone falls, and pounds the degree of deformation for the pipe for escaping being placed below Hanging Basket, then recording pipeline, degree of cracking and breaks
Bad degree detects the anti-ability of pounding of pipe for escaping.
