Abstract
The utility model discloses an adjustable front canopy lifting ring device which comprises a U-shaped piece for processing phi20mm deformed bars. An upper clamping plate and a lower clamping plate are arranged on the U-shaped piece and fixed on the same through adjusting nuts, two ports of the U-shaped piece are welded by a strip plate, a through hole is processed in the strip plate, and a fixing nut matching with an anchor rod is welded on the through hole. In use, each front canopy is lifted by the two devices. During mounting, the anchor rod is mounted on the roof, the device is screwed on the anchor rod, the front canopy is placed between the two clamping plates, and height of the front canopy can be adjusted by the adjusting nuts to enable the front canopy to tightly support the roof and be locked. Therefore, the problem about vertical adjustment of the front canopy is solved, the front canopy is enabled to well tightly support the roof, and safety of a driving working face is improved.
Description
Technical field
The utility model relates to the servicing unit that laneway temporary support is used.
Background technology
At present, when tunnelling, generally adopt forestope temporary lining.During forestope temporary lining, forestope need be arranged on face roof.Hanging-ring type forestope is interim installation suspension ring on face roof, then forestope is inserted in suspension ring.Current suspension ring can not regulate the upper-lower position of forestope, can not make forestope hold in the palm well and press closer plate, can not lock forestope, directly have influence on driving face operating personnel's life security.
Summary of the invention
The purpose of this utility model is in order to lock forestope, and a kind of adjustable front canopy hoisting ring device is provided.
A kind of adjustable front canopy hoisting ring device, it is characterized in that, it comprises a U-shaped part of processing with screw-thread steel, on U-shaped part, be provided with upper and lower clamping plate, upper and lower clamping plate are fixed on U-shaped part by adjusting nut, the two-port of U-shaped part is welded with batten, is processed with through hole on batten, welds a hold-down nut with anchor rod-matched on through hole again.
During use, every forestope is sling by two these devices.During installation, skyhook on top board, is tightened on this device on anchor pole, between two clamping plate, puts into forestope, and forestope height can be adjusted by adjusting nut, makes forestope holder press closer plate, and locking.Thereby the upper-lower position that has solved forestope regulates problem, forestope is held in the palm well and press closer plate, has improved the safety of driving face.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the adjustable front canopy hoisting ring device of the utility model;
Fig. 2 is the lateral view of Fig. 1.
Marginal data, 1-U shape part, 2-clamping plate, 3-adjusting nut, 4-batten, 5-hold-down nut, 6-anchor pole, 7-forestope.
The specific embodiment
As shown in Figure 1, 2, a kind of adjustable front canopy hoisting ring device, it comprises a U-shaped part 1 of processing with Ф 20mm screw-thread steel, on U-shaped part, 1 is provided with upper and lower a pair of clamping plate 2, upper and lower clamping plate 2 are fixed on U-shaped part by adjusting nut 3, the two-port of U-shaped part 1 is welded with batten 4, on batten 4, is processed with through hole, on through hole, weld again one with the supporting hold-down nut 5 of anchor pole 6.
During installation, on top board, skyhook 6, and this device is tightened on anchor pole 6, between two clamping plate 2, put into forestope 7, and forestope 7 height can be adjusted by adjusting nut 3, make forestope 7 holders press closer plate, and locking.
