Abstract
The utility model discloses a temporary bracket of a front canopy, which comprises a top network shaped like an arc surface. A lifting mechanism is arranged at the bottom support part of the top network. When the utility model is used, the lifting mechanism can be moved below the top surface of the roadway which requires supporting; a metal mesh is laid on the arc surface of the top network; the lifting mechanism is used for lifting the top network; the arc surface of the top network can closely cling to the bottom surface of the arch part of the top surface of the roadway; the metal mesh is fixedly connected with the top surface through a fixing element; then the lifting mechanism can put down the top network and is moved to the next working location; the steps are repeated; and the next metal mesh can be fixedly connected and supported.
Description
Technical field
The utility model relates to the temporary lining instrument of mining tunnel ceiling, especially a kind of forestope falsework.
Background technology
Mine working face is after blowing out, need the wire lath sheet be installed at the tunnel end face of newly leaving reinforces, before fixing metal net sheet, need the wire lath sheet is carried out supporting, existing forestope by three mutually independently steel pipe form, hang in the forestope ring on the good end face of supporting, behind every driving one segment distance, forestope need be released from the forestope ring, insert in the forestope ring of newly squeezing on the opposite, when going into to encircle, need two people to catch and aim at, its workflow is quite complicated: link, wear beam, back of the body wood needs another mistake to do once during dismounting, so complicated operation and to delay the time more; And because in the complicated topographical conditions that meets the forestope place, the workman also is not easy to catch forestope, pounds the accident of hurting sb.'s feelings and easily cause forestope to drop.
The utility model content
The utility model purpose is to provide a kind of dismountable forestope falsework that is supported between bottom surface, top, tunnel.
The technical solution of the utility model is: the forestope falsework, comprise the top net that is shaped as cambered surface, and the top sieve bottom supports and is provided with elevating mechanism.
Described elevating mechanism is to be made of the upper and lower ut socket that firm banking and upper/lower terminal all have the leading screw of screw thread and be connected to top sieve bottom and firm banking top, and the thread rotary orientation of the thread segment at described leading screw two ends is opposite and is rotated in respectively in the upper and lower ut socket.
Top net stent support by a plurality of cambered surface circle distribution of netting along the top between described top net and the elevating mechanism connects.
The top of described top net support is the del framework.
The utility model in use, elevating mechanism can be removed to the below of the tunnel end face that needs supporting, the wire lath sheet is laid on the cambered surface of top net, using elevating mechanism will push up net then rises, and the cambered surface that makes top net fits tightly on the bottom surface, arch of the end face in tunnel, with fixture wire lath is connected on the end face of tunnel then, the reduction elevating mechanism puts down the top net and elevating mechanism is moved to next working position again after finishing, and repeats the supporting that is connected that aforesaid operations can be finished next piece wire lath.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the vertical view of Fig. 1;
Fig. 3 is the structural representation of top of the present utility model net support.
The specific embodiment
As Fig. 1, Fig. 2, shown in Figure 3, forestope falsework of the present utility model comprises the top net 2 of the frame construction that is shaped as cambered surface, top net 2 is fixed on the top net bottom seat 8 by three top net supports 1, net bottom seat 8 lower ends, top are fitted with top nut sleeve 3, each top net support 1 is along the support and connection of the cambered surface circle distribution of top net 2, and the top of described top net support 1 is the del framework.Firm banking 7 tops are fixed with on the lower nut sleeve 6, upward, ut socket 3,6 has relative screwed hole, be installed with leading screw 4 in the screwed hole, the upper end spinning of leading screw 4 is in the screwed hole of top nut sleeve 3, the lower end spinning of leading screw 4 is in the screwed hole of lower nut sleeve 6, and the thread rotary orientation of leading screw 4 upper and lower thread segments is opposite.The middle part of leading screw 4 has the through hole 7 that inserts for rotary handle.Because the thread rotary orientation of leading screw 4 upper and lower thread segments is opposite, at rotating threaded shaft 4 and top net 2 and firm banking 7 when all not rotating, leading screw is screwed out from two screwed holes simultaneously or screws in, thereby realize the increase of top net 2 and firm banking 7 spacings or dwindle.
Claims (4)
1, forestope falsework is characterized in that: comprise the top net that is shaped as cambered surface, the top sieve bottom supports and is provided with elevating mechanism.
2, forestope falsework according to claim 1, it is characterized in that: described elevating mechanism is to be made of the upper and lower ut socket that firm banking and upper/lower terminal all have the leading screw of screw thread and be connected to top sieve bottom and firm banking top, and the thread rotary orientation of the thread segment at described leading screw two ends is opposite and is rotated in respectively in the upper and lower ut socket.
3, forestope falsework according to claim 1 and 2 is characterized in that: the top net stent support by a plurality of cambered surface circle distribution of netting along the top between described top net and the elevating mechanism connects.
4, forestope falsework according to claim 3 is characterized in that: the top of described top net support is the del framework.
