Description
TECHNICAL FIELD
[0001] The utility model belongs to pipeline butt joint technical field, concretely relates to a kind of metal mine reserved filling pipeline butt joint's fixing device. BACKGROUND
[0002] In the production and operation process of metal mine filling method stope, strengthening filling process management can effectively reduce mine subsidence and ground subsidence, and the scientific and safe layout of filling pipeline is of great significance to underground production and operation and cost control of mine. The traditional filling method stope filling is carried out by upward shallow hole drilling and blasting on the roof of the stoping approach, which is connected with the upper filling communication passage, one end of the PVC pipe is connected with the filling pipeline, and the other end extends to the filling preparation approach, and then the filling work is completed. The main disadvantage of this method is that the labor intensity of workers is high, the work efficiency is low, and the safety of workers cannot be effectively guaranteed. At present, the polyethylene spiral corrugated pipe reserved filling pipeline used in filling method stope reduces the operation difficulty to a certain extent, but the corrugated pipe butt joint is not tight and difficult to fix, and the phenomenon of dust leakage occurs from time to time, and there is no effective fixing device. Therefore, it is necessary to develop a kind of metal mine reserved filling pipeline butt joint fixing device to solve the problem. CONTENT OF UTILITY MODEL
[0003] The utility model provides a kind of metal mine reserved filling pipeline butt joint fixing device, to solve the phenomenon that corrugated pipe pipeline cannot be effectively fixed, leading to easy dust leakage.
[0004] Therefore, the utility model adopts the following technical scheme:
[0005] A kind of metal mine reserved filling pipeline butt joint fixing device, including half-cylinder upper ring and half-cylinder lower ring, the two ends of upper ring and lower ring are distributed and connected with rim plate, a plurality of round holes are formed in rim plate, screw rod is installed in round hole after upper ring and lower ring are buckled;
[0006] Upper ring includes stable steel plate and arc steel belt, stable steel plate is long strip, a plurality of interval-distributed semicircular openings are formed in lower edge of stable steel plate, the shape of semicircular opening corresponds to the wave crest of corrugated pipe, and opening is used for being clamped at wave crest of corrugated pipe;Arc steel belt is bent into semicircle, and the arc steel belt includes a plurality of, and a plurality of arc steel belts are interval-distributed, and arc steel belt is used for being clamped in wave trough of corrugated pipe, and arc steel belt top center is connected to stable steel plate;Rim plate is connected to the end of arc steel belt.
[0007] The utility model discloses a beneficial effect lies in: this device is used in metal mine filling method stope reserved filling pipeline butt joint work, effectively solved the problem such as the butt joint of bellows not airtight, difficult to fix, reduced cost loss, simplified operation procedure, effectively improved the working efficiency of filling method stope reserved filling pipeline butt joint fixing procedure. BRIEF DESCRIPTION OF DRAWINGS
[0008] Figure 1 It is structure schematic drawing of the utility model;
[0009] Figure 2 The utility model fixed filling pipeline cross section;
[0010] In the drawing: 1 - firm steel sheet, 2 - gap, 3 - arc steel band, 4 - rim plate, 5 - connecting bolt, 6 - screw rod, 7 - bellows trough, 8 - bellows crest. DETAILED DESCRIPTION
[0011] The utility model will be further described in connection with the drawings and specific embodiment:
[0012] A kind of metal mine reserved filling pipeline fixed device of butt joint, including half-cylinder upper and lower embrace ring, and the two ends of upper embrace ring and lower embrace ring are distributed with rim plate 4 connection, and several round holes are set up on rim plate 4, and screw rod 6 is installed in round hole after upper embrace ring and lower embrace ring buckle and form cylinder, and fixed.
[0013] Upper embrace ring includes firm steel sheet 1 and arc steel band 3, firm steel sheet 1 is long strip, and multiple interval distribution's semicircular gap 2 is set up in the lower edge of firm steel sheet 1, the shape of semicircular gap 2 corresponds with bellows crest, and gap 2 is used to be clamped at bellows crest;Arc steel band 3 is bent into semicircle, and arc steel band 3 includes multiple, and multiple arc steel band 3 interval distribution, and arc steel band 3 is used to be clamped in bellows trough, and arc steel band 3 top center is connected to firm steel sheet 1;Rim plate 4 is connected to the end of arc steel band 3.
[0014] First, arc steel band 3 is connected with firm steel sheet 1 using connecting bolt 5, here, arc steel band 3 is not less than 5 groups, to ensure that the pipeline can be stably butt joint;Second, the gap 2 of steel band firm steel sheet 1 is clamped tightly bellows crest, to prevent arc steel band 3 from separating from bellows trough due to longitudinal tension during fastening process;Finally, two arc steel bands 3 are connected using screw rod 6, and are fastened by adjusting nut, to realize the fixation of filling pipeline butt joint.
