Abstract
The utility model discloses an it prevents rotary device initiatively to articulate formula shield structure single cylinder hydro -cylinder, prop boots, prop the boots backing plate and prevent changeing the piece including well shield rear portion, tail shield, thrust cylinder, round pin axle, chain, single cylinder, well shield rear portion and tail shield pass through bolted connection, thrust cylinder fixes on well shield rear portion, the single cylinder props boots and passes through pivort fixation on thrust cylinder, the single cylinder prop boots and be fixed with the single cylinder and prop boots board, the single cylinder prop on the boots board welding and have and prevent changeing the piece. The utility model discloses thrust cylinder is flexible when the section of jurisdiction is assembled to shield structure machine, and the single cylinder hydro -cylinder props boots and takes place to deflect, prevents changeing the piece and takes place the friction with the tail shield, restricts that its is rotatory, and the single cylinder hydro -cylinder props the boots board of boots, and can not push away the section of jurisdiction sealed, has reduced the damage probability that sealed the section of jurisdiction. The utility model discloses be favorable to improving the efficiency and the quality of assembling the section of jurisdiction, simple structure, operation convenient to use.
Description
Technical field
The utility model belongs to tunnel shield machine tunneling construction apparatus field, is specially a kind of initiatively articulated shield single cylinder oil cylinder anti-rotation device.
Background technology
Along with economic development, the quickening of urbanization process, the tunnels such as city underground, water conservancy and hydropower, highway, railway all need shield structure to excavate, and shield structure waits many advantages safely and fast with it and popularizes gradually.
At present in constructing tunnel process, shield machine can be divided into initiatively articulated shield machine and two kinds, passive articulated shield machine by articulated form, initiatively articulated shield machine because of its advantage use also many.Shield machine is when tunneling, and single cylinder oil cylinder support boots can rotate, and make support boots encounter shield tail, and cause support boots wearing and tearing shield tail, support boots backing plate also can be caused to encounter section of jurisdiction sealing, and section of jurisdiction sealing is easily damaged.
Current each producer mainly contains three kinds for the upper method adopted of this phenomenon design: 1, arrange guide pad at shield tail, although all get back to original position when this design can make support boots regain at every turn, as long as but propulsion cylinder releases support, and boots still can rotate, the boots plate of propulsion cylinder support boots also can be shifted onto in the sealing of section of jurisdiction; 2, support boots are done greatly as much as possible, reduce the rotational angle of support boots, the boots plate of same propulsion cylinder support boots also can be shifted onto in the sealing of section of jurisdiction, and when little curve is turned, propulsion cylinder support boots can shift reinforcing ring onto; 3, when shield tail encountered by each propulsion cylinder support boots, become a full member by manpower handle support boots, this mode is time-consuming, effort.
Therefore, push away bad section of jurisdiction sealing probability for reducing when single cylinder oil cylinder provides one to use, have the device that good anti-single cylinder oil cylinder rotates, be a urgent problem simultaneously.
Summary of the invention
In order to overcome above-mentioned deficiency of the prior art, it is simple that the utility model provides a kind of structure, easy for operation, can ensure that propelling cylinder can not rotate at telescopic process support boots, during use, reduce the active articulated shield single cylinder oil cylinder anti-rotation device pushing away bad section of jurisdiction sealing probability.
The purpose of this utility model is achieved in that
A kind of initiatively articulated shield single cylinder oil cylinder anti-rotation device, comprise middle shield rear portion 1, tail shield 2, propelling cylinder 3, bearing pin 4, chain 5, single cylinder support boots 6, support boots backing plate 7 and Anti-rotary block 8, described middle shield rear portion 1 and tail shield 2 are bolted, propelling cylinder 3 is fixed on middle shield rear portion 1, and single cylinder support boots 6 are fixed on propelling cylinder 3 by bearing pin 4; Described single cylinder support boots 6 are fixed with single cylinder support boots boots plate 7, described single cylinder support boots 6 are welded with Anti-rotary block 8;
Chain 5 is provided with between described single cylinder support boots 6 and propelling cylinder 3; Described chain 5 right-hand member is welded on single cylinder support boots 6, and left end is fixed on propelling cylinder 3.
positive beneficial effect:the utility model is when shield machine thrust oil cylinder stretches, and single cylinder oil cylinder support boots deflect, and Anti-rotary block and tail shield rub, and limit it and rotate, and makes single cylinder support boots boots plate and pushes away less than section of jurisdiction sealing, reduce the damage probability of section of jurisdiction sealing.The utility model is conducive to the efficiency and the quality that improve segment assembly, and structure is simple, easy for operation.

Detailed description of the invention
As shown in Figure 1, Figure 2, shown in Fig. 4 and Fig. 5, shown a kind of initiatively articulated shield single cylinder oil cylinder anti-rotation device, comprise middle shield rear portion 1, tail shield 2, propelling cylinder 3, bearing pin 4, chain 5, single cylinder support boots 6, support boots backing plate 7 and Anti-rotary block 8, described middle shield rear portion 1 and tail shield 2 are bolted, propelling cylinder 3 is fixed on middle shield rear portion 1, and single cylinder support boots 6 are fixed on propelling cylinder 3 by bearing pin 4; Described single cylinder support boots 6 are fixed with single cylinder support boots boots plate 7, described single cylinder support boots 6 are welded with Anti-rotary block 8;
As shown in Figure 3, chain 5 is provided with between described single cylinder support boots 6 and propelling cylinder 3; Described chain 5 right-hand member is welded on single cylinder support boots 6, and left end is fixed on propelling cylinder 3.
Utility model works principle is: shield machine is when segment assembly, propelling cylinder 3 is regained, single cylinder support boots 6 deflect, Anti-rotary block 8 and tail shield 2 are adjacent to, prevent single cylinder to support boots 6 and again deflect, when propelling cylinder 3 stretches out, Anti-rotary block 8 is still adjacent to tail shield 2, support boots backing plate 7 can not seal with section of jurisdiction and contact, and decreases the probability pushing away the sealing of bad section of jurisdiction, ensures segment assembly efficiency and quality.
The utility model propelling cylinder when shield machine segment assembly stretches, and single cylinder oil cylinder support boots deflect, and Anti-rotary block and tail shield rub, and limit it and rotate, and the support boots boots plate of single cylinder oil cylinder support boots pushes away less than section of jurisdiction sealing, reduces the damage probability of section of jurisdiction sealing.The utility model is conducive to the efficiency and the quality that improve segment assembly, and structure is simple, easy for operation.
Above embodiment is only for illustration of preferred embodiments of the present utility model; but the utility model is not limited to above-mentioned embodiment; in the ken that described exercising ordinary skill possesses; the any amendment done within spirit of the present utility model and principle, equivalently to substitute and improvement etc., it all should be encompassed within the technical scheme scope of the utility model request protection.
