Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of tunnel construction equipment, in particular to a water pipe supporting device based on an open TBM synchronous lining trolley. BACKGROUND

[0002] The open TBM is a tunnel construction complete equipment integrating machine, electricity, hydraulic pressure, sensing, information technology, etc. While the open TBM is excavated, synchronous concrete lining operation is generally performed, so that the tunnel excavation and lining are changed from single-process operation to parallel flow operation, which can provide tunnel construction safety and overall construction efficiency.

[0003] The synchronous lining operation is usually performed by a synchronous lining trolley. Since the TBM in front is still in the state of tunneling during the synchronous lining operation, the tunneling of the TBM needs to be matched with water pipes, air pipes, belts and other mechanisms, so that the synchronous lining trolley needs to pass through the above pipelines during the synchronous lining operation. Since the water supply demand is large during the tunneling construction of the large-diameter open TBM, the pipe diameter of the water supply pipeline is usually between 200-300 mm, the length of a single pipe can be dozens of meters, and the weight of the pipe body is large. In order to avoid the influence of the water pipe body on the normal passage of the construction vehicle equipment in the formed tunnel, the pipeline is usually hoisted at the top of the tunnel. Since the posture of the TBM is constantly adjusted during the tunneling process, the water pipe pipeline is difficult to reach the ideal straight state with the extension of the tunneling, and the height and slope are difficult to unify the standard.

[0004] In addition, during the synchronous lining construction, in order to ensure the passage of the synchronous lining trolley and the construction of the synchronous lining, the water pipe and the lifting point at the top of the tunnel are temporarily removed. At this time, in order to provide traction for the pipe body of the removed lifting point, the pipe body is usually suspended in the trolley. However, the strength of the template structure inside the trolley is limited, and the heavy pipe body has the risk of deforming the trolley template, which affects the structural stability of the synchronous lining trolley.

[0005] The information disclosed in this BACKGROUND section is only for the purpose of enhancing the understanding of the background of the present disclosure and should not be considered as admitting that the information forms the prior art known to those skilled in the art. SUMMARY

[0018] In the description of the present application, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inner", "outer", "vertical", "horizontal", "clockwise", "counterclockwise" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the present application.

[0019] In order to better understand the technical solutions of the present application, the above technical solutions will be described in detail below in combination with the drawings in the specification and specific embodiments.

[0020] In the process of synchronous lining construction by using a synchronous lining trolley, due to the influence of the water pipe body lifting point on the travel and lining operation of the synchronous lining trolley, the lifting point needs to be temporarily removed. In the prior art, in order to avoid the lack of effective and reliable traction support for the water pipe body after removing the lifting point, the water pipe body lifting point is lifted and arranged at the formwork of the synchronous lining trolley. Due to the heavy weight of the water pipe body, the formwork of the synchronous lining trolley is deformed, etc. Therefore, the present example discloses a water pipe support device based on an open type TBM synchronous lining trolley.

[0021] Specifically, in order to avoid the deformation of the structure such as the formwork of the synchronous lining trolley caused by the lifting method, the water pipe support device is fixedly arranged at the beam body of the synchronous lining trolley which has high structural strength, so as to provide reliable support force for the heavy water pipe by the water pipe support device. At the same time, due to the relatively high structural strength of the beam body, the beam body can still maintain its structural reliability when the water pipe load is completely applied to the beam body, and deformation and other problems will not occur. In order to realize the fixed arrangement of the water pipe support device at the synchronous lining trolley, see Figure 1 , the water pipe support device comprises a base 1. In the present embodiment, the base 1 specifically adopts an I-beam with high strength, so as to ensure the structural stability of the base after being subjected to force. The bottom surface of the base 1 is provided with a bolt hole, so as to realize the relative fixation between the base 1 and the synchronous lining trolley by means of bolts. In this way, the base 1 is relatively fixed to the beam body of the synchronous lining trolley at the position below the water pipe line to be supported by means of bolts, so as to provide effective support for the water pipe with removed lifting point by the water pipe support device.

[0022] In some other embodiments, considering that the water pipe line in the tunnel is difficult to extend straight due to the constant adjustment of the TBM working posture, and the overall slope, height, etc. are uneven, in order to ensure that the water pipe support device can still provide effective support to the excessively curved pipe line, in this embodiment, the bolt hole provided at the bottom surface of the base 1 is long strip-shaped, the length direction of the long strip-shaped bolt hole is parallel to the length direction of the base, thereby the base fixing position can be adaptively adjusted along the length direction within the length range of the bolt hole, so as to adapt to the running direction of the pipe line and provide reliable and effective support force to the pipe line.

[0023] In order to realize the support to the water pipe body, in this embodiment, referring to Figure 1 , the water pipe support device further comprises a cross beam 2, and a plurality of supporting rollers 3 are fixedly arranged on the top surface of the cross beam 2, thereby the supporting rollers 3 are in contact with the outer edge surface of the water pipe body, so as to realize the support to the pipe body with the lifting point removed.

[0024] However, also considering the non-straight state of the water pipe line extending in the tunnel, the height of the pipe line changes obviously, in order to adapt to the height position of the pipe line and provide effective support to the pipe line, in this embodiment, referring to Figure 1 , a power element 4 is arranged between the cross beam 2 and the base 1, and the power element is used to stretch and contract in the direction perpendicular to the base 1, so as to realize the adjustment of the height position of the cross beam 2, since the supporting rollers 3 are fixed on the top of the cross beam 2, the adjustment of the height position of the supporting rollers 3 is realized by adjusting the height of the top support of the power element 4, so as to adaptively support the pipe line at different height positions.

[0025] Specifically, in this embodiment, the power element 4 is a jack, and the cross beam 2 is arranged in parallel to the length direction of the base 1, and the roller shaft of the supporting roller 3 is parallel to the length direction of the cross beam 2, so that the supporting roller provides support in the direction nearly perpendicular to the pipe body below the water pipe body, and since the supporting roller 3 can rotate along the roller shaft, the friction between the supporting roller 3 and the water pipe body during the synchronous lining trolley running can be reduced, and the abrasion of the pipe body can be reduced. In addition, since the water pipe body is heavy, in order to ensure the support reliability, at least two power elements are arranged to act synchronously, in this embodiment, two jacks are arranged, and the two jacks are symmetrically fixed on the top of the base 1, so as to ensure that the support force of the cross beam 2 is balanced. In order to ensure the synchronous action of the two jacks, in this embodiment, the water pipe support device further comprises a hydraulic pump station for controlling the synchronous action of the two jacks, so as to realize the stable lifting of the cross beam 2.

[0026] In order to ensure the stable lifting of the cross beam 2 and the relative stability of the position of the cross beam along the running direction of the synchronous lining trolley during the running of the trolley, in this embodiment, referring to Figure 1The two sliding grooves 5 are vertically fixed on the top surface of the base 1, and symmetrically arranged on the two sides of the base 1 along the length direction of the base 1. The two ends of the cross beam 2 are respectively slidably embedded in the two sliding grooves 5. In this example, the sliding groove 5 is a channel steel, and the two notches are oppositely arranged. The length of the cross beam 2 matches the distance between the two groove bottoms. Thus, the cross beam 2 is limited by the sliding groove 5, and can stably move along the direction perpendicular to the base 1, i.e. the length direction of the sliding groove. In addition, in order to ensure the fixing reliability between the sliding groove 5 and the base 1, and to avoid the connection part from being broken under stress, in this embodiment, a rib plate 51 is fixedly arranged on the two sides of the sliding groove 5, and the bottom surface of the rib plate 51 is fixedly supported on the base 1. Thus, the relative fixing strength between the sliding groove 5 and the base 1 is enhanced, and the stress reliability of the sliding groove 5 is improved.

[0027] In addition, in this embodiment, the distance between the two sliding grooves 5 is greater than the diameter of the water pipe body to be supported. Thus, when the position of the power recovery device, i.e. the position of the supporting roller 3, is at the lowest point, the supporting roller can still effectively support the pipe body, and the position interference between the two sliding grooves 5 and the water pipe body can be avoided. In some other embodiments, in order to avoid the two ends of the cross beam 2 from affecting the smoothness of the cross beam 2 moving along the sliding groove 5 due to uneven cutting, in this example, a channel steel embedded in the sliding groove 5 is welded and fixed on the two ends of the cross beam 2, and lubricating oil is coated on the contact surface between the channel steel and the sliding groove 5, so as to ensure the smoothness of the cross beam moving along the sliding groove, and reduce the operation noise.

[0028] Referring to Figure 1 In this example, the middle part of the supporting roller 3 has a smaller diameter than the two end parts, and the whole supporting roller 3 has a shape of hourglass. Thus, the guiding effect on the water pipe body is achieved, the pipe body is relatively located at the middle part of the supporting roller 3, and the supporting effect is improved. In addition, in order to avoid the abrasion of the contact surface between the supporting roller 3 and the water pipe body due to the hard contact, in this embodiment, a buffer layer is coated on the outer edge surface of the supporting roller 3. In this example, the buffer layer is a rubber layer.
