Description
Technical field
The utility model belongs to tunnelling or tunnel repair during forestope temporary lining technical field.
Background technology
In the colliery during excavation, in order to guarantee construction safety, often will use forestope to carry out temporary lining during repairing in tunnelling or tunnel, and forestope be hinged on the supporting of main canopy the place ahead usually at no column space top board place at work plane.At present, the solid unit of the forestope that the down-hole shed shoring is used mainly contains following three kinds of modes: first kind is with chain forestope directly to be snapped on the h beam cap, exists overlap joint insecure, the problem that comes off easily, and operation is very inconvenient.Second kind is directly to snap into forestope on the h beam cap with suspension ring; But whitewashing is uneven sometimes, causes the fixing, mobile all very difficult of forestope, and inconvenient operation; Suspension ring also often occur by top board and steel I-beam extruding, and can't take off the problem of recycling.The third is to go up hold-down nut and leading screw at Z word beam (steel plate system), and processing U-shaped carriage and adjustment screw mandrel, and is provided with at corresponding site and strengthens gusset and improve intensity, realizes the adjusting of the fixing and forestope of corresponding site.The processing of this each parts of device and use cumbersomely is unfavorable for large-scale promotion application.
The utility model content
The purpose of the utility model provides a kind of safe and reliable, easy to operate, can reusable driving face temporary support device.
To achieve these goals; The utility model comprises: top, top pawl, preceding spy girder steel, go up top pad, secondary sleeve pipe, set screw, one-level sleeve pipe, down the top pad, twist thick stick, elevating mechanism, setting of casing, base, bottom connecting rod, middle part connecting rod; Top, top pawl, last top pad are fixed on secondary sleeve pipe upper end successively; Be with the one-level sleeve pipe in secondary sleeve pipe bottom, fix one-level by set screw between secondary sleeve pipe and the one-level sleeve pipe
The sleeve pipe lower end is set with down top pad and elevating mechanism successively, is set with setting of casing and base successively in the lower end of elevating mechanism, and is fixing by the connection of bottom connecting rod between the setting of casing, connected fixing between the elevating mechanism by the middle part connecting rod.
Described elevating mechanism is made up of strand thick stick, housing, swivel nut, screw rod, is provided with swivel nut in the housing, and strand thick stick and screw rod connect as one, and screw rod is screwed in the swivel nut.
Top, described top pawl is the semicircular arc structure.
Like this, during tunnelling or tunnel repairing, need be when work plane uses forestope temporary lining; The utility model is installed to heading end, preceding spy girder steel is set in the pawl of top, top, according to height of tunnel; Flexible secondary sleeve pipe also utilizes set screw to fix; Utilize strand thick stick adjustment elevating mechanism, the spy girder steel tightly withstands the place ahead supporting before making is not had column space top board place, and the workman can carry out the roadway support construction safely.After finishing, construction withdraws from this device, in order to using next time.Have characteristics such as easy to operate, flexible, that compliance is strong.
Description of drawings
Below in conjunction with accompanying drawing the utility model is done further explain.
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the lateral view of the structural representation of the utility model.
Fig. 3 is the cross-sectional view of elevating mechanism.
The specific embodiment
Can know that by Fig. 1, Fig. 2, Fig. 3 the utility model comprises: top, top pawl 1, preceding spy girder steel 2, go up top pad 3, secondary sleeve pipe 4, set screw 5, one-level sleeve pipe 6, top pad 7, strand thick stick 8, elevating mechanism 9, setting of casing 10, base 11, bottom connecting rod 12, middle part connecting rod 13 down.Top, top pawl 1, go up top pad 3 and be fixed on secondary sleeve pipe 4 upper ends successively, top, top pawl 1 is set to the semicircular arc structure, visits the security and stability of girder steel before can effectively guaranteeing.Be with one-level sleeve pipe 6 in secondary sleeve pipe 4 bottoms, according to tunnel height needs, the secondary sleeve pipe can stretch up and down in the one-level sleeve pipe, and then is fixed by set screw 5.One-level sleeve pipe 6 lower ends are set with down top pad 7 and elevating mechanism 9 successively.Elevating mechanism is made up of last strand thick stick 8, housing 14, swivel nut 16, screw rod 17, is provided with swivel nut 16 in the housing 14, and strand thick stick 8 connects as one with screw rod 17, and screw rod 17 is screwed in the swivel nut 16, and elevating mechanism can be set to two cover rotating mechanisms up and down, to enlarge lifting travel.Top and the bottom at elevating mechanism are provided with rolling bearing 15 respectively, so that when using the strand thick stick to rotate, one-level sleeve pipe 6 can steadily raise, setting of casing 10 steadily supports and reduces to operate resistance.Be set with setting of casing 10 and base 11 successively in the lower end of elevating mechanism 9, beaded support and spherical base are adopted in the setting of casing bottom, make the base can the deflection certain angle, make things convenient for the scene to install and use.Secondary sleeve pipe 4, one-level sleeve pipe 6, elevating mechanism 9, setting of casing 10 are that two rows, three row modes are arranged and are connected to form an integral body, so that supporting with other facilities, satisfy the operation habit needs.Fixing between the setting of casing 10 by 12 connections of bottom connecting rod, connect fixing by middle part connecting rod 13 between the elevating mechanism 9.When the amplitude of regulating is big, can realize that effectively realized the coarse adjustment of device, two cover rotating mechanisms of elevating mechanism are regulated the meticulous adjusting of implement device through stretching of secondary sleeve pipe.Each parts all adopt mining steel processing and fabricating and carry out surface anticorrosion and handle, to satisfy the subsurface environment requirement.
