Description
Technical field
The utility model relates to a kind of multi-functional anti-down canopy and protects ejection device in advance.
Background technology
In the work progress in mine digging tunnel, what generally adopt is bursting work, adopts the metallic support shed to carry out supporting.The supporting shed because shot firing operation is easy to collapse, so the constructor is through the empty top operation down of being everlasting.After shed was collapsed, the constructor need get up shed supporting again.Not only increased the constructor workload and labour intensity, reduced efficiency, and the constructor need face possible roof fall danger during the operation of empty top, and constructor's safety has been brought very big threat.In traditional bursting work through regular meeting the accident that slag stone falls to hurting sb.'s feelings takes place.At present known anti-down shed device can be divided into two kinds substantially, and first kind is the disclosed a kind of flat key type reversion prevention apparatus of Chinese patent CN87216591, is made up of connecting rod, moving pawl, moved end head, cotter pilotage brake shoe, quiet pawl, quiet termination; Second kind is the novel anti-down shed device of the disclosed a kind of opening driving of Chinese patent CN20082014615.7, is made up of outer tube, inner sleeve, the flat groove of circular arc, wedge, cambered surface channel-section steel etc.Above-mentioned two kinds of anti-down shed devices have following shortcoming: 1. complex structure, manufacturing cost is higher.2. it is single to be connected and fixed mode, because shed ding support belongs to passive protecting, could stablize supporting when only having pressure on top board.And field operation has stress-free situation on the short-term top board, and supporting this moment shed does not stress, poor stability, thus make that the whole anti-down property of above-mentioned anti-down shed device is relatively poor.3. function singleness can only be limited to the anti-down use of a certain shed.
The utility model content
The purpose of this utility model be to provide a kind of simple in structure, can active support and be applicable to the multi-functional anti-down canopy of multiple shed and protect ejection device in advance.
For achieving the above object, multi-functional anti-down canopy of the present utility model and protect ejection device in advance and comprise a semicircle buckle, a steel pipe and two clamps, every clamp has included plate body, and be arranged with following structure on the plate body of two clamps: the middle part of every plate body of a. is provided with at least two connecting hole; B. the top of every plate body is fixedly connected with Ka Zui, and the shape of Ka Zui and shed structure are complementary; C. the bottom of every plate body is fixedly connected with the semicircle draw-in groove, and identical and the two the internal diameter of the internal diameter of the internal diameter of described semicircle draw-in groove and described semicircle buckle all is complementary with the external diameter of described steel pipe; The two ends of described semicircle draw-in groove are extended to the left and right and are provided with left junction plate and right junction plate, are respectively equipped with left fixed bolt hole and right fixed bolt hole on the left and right junction plate; The two ends of described semicircle buckle are extended to the left and right and are provided with left buckle junction plate and right jamming button junction plate, be respectively equipped with left and right snap fit bolt hole on the left and right buckle junction plate, the corresponding setting of left and right fixed bolt hole on left and right snap fit bolt hole and two clamps.
The middle part of the plate body of every clamp is provided with two connecting holes; Respectively be provided with a fixed bolt hole on the left and right junction plate of described clamp; Correspondingly on the described left and right buckle junction plate respectively be provided with two fixed bolt holes with the fixed bolt hole on the left and right junction plate.
The material of all parts in the utility model is rigid material.
The utlity model has following advantage:
1. compare with the anti-down shed device of two kinds of forms in the prior art, the utility model is structurally more simple, and manufacturing cost is lower.During use, first is that Ka Zui on two clamps is relative, makes Liang Kazui block the both sides of shed; The secondth, wear movable bolt 5 in the connecting hole on clamp, the Ka Zui of two clamps is pressed on the structure of shed behind the fastening bolt, thereby two clamps is fixed on the both sides of the good shed of supporting; The 3rd is that steel pipe is put into semicircle draw-in groove on the clamp, the semicircle buckle is pressed on the steel pipe of semicircle draw-in groove opposite side, by wearing bolt in the fixed bolt hole on left and right junction plate and left and right buckle junction plate semicircle buckle and semicircle draw-in groove are compressed, thus the chucking steel pipe.Behind the chucking, the utility model plays the active support effect by structures such as Ka Zui, steel pipes to shed, need not exist pressure to play support action to shed in the shed top, thereby strengthen the stability of supporting.Be arranged to the shape and the size that are complementary with the shed structure according to the shape of shed structure (as i iron or U shaped steel) and big young pathbreaker Ka Zui, the utility model just can play the support action of anti-down canopy to multiple shed like this.
2. respectively be provided with a fixed bolt hole on the described left and right junction plate, simple in structure, easy to use.
3. the material of all parts is rigid material, guarantees effectively to play support action.
