Description

Technical Field

[0001] This utility model relates to the field of tunnel engineering equipment technology, specifically to a tunnel construction integrated machine with a guiding structure. Background Technology

[0002] In tunnel construction, the installation of arch frames is a crucial step in the initial support system. Arch frames include folding arch frames, which are support structures that can be quickly assembled and disassembled. They are commonly used for temporary buildings, activity areas, and tunnel construction. Folding arch frames typically include side arches located on both sides. In existing technologies, the installation process usually relies on a series of complex mechanical devices and manual operations. The specific implementation is as follows: First, a loader transports the folding arch frame to the rear of the support frame; then, the main boom of the support frame grabs the folding arch frame and opens the side arches using left and right lifting mechanisms; next, the side arch grabbing mechanism grabs the opened side arch sections and, working in conjunction with the main boom, transports the arch frame to the tunnel face via a sliding assembly; finally, the arch frame is installed at the tunnel face.

[0003] In existing technology, guide sliding tubes are only installed on the left and right sides of the platform, but these tubes do not extend to the front and rear sides of the platform. After the folding arch frame is opened by the lifting mechanism, the side arches tend to retract inward due to gravity. Since the guide sliding tubes do not extend to the lifting mechanism at the rear of the platform, when the folding arch frame is moved from the lifting mechanism to the tubes, the inward retraction of the side arches often prevents the arch frame from being smoothly transferred onto the guide sliding tubes, affecting the efficiency of the arch frame's transfer. In addition, there is a relatively long distance (2-3 meters) between the front end of the platform and the arch erection area. Because the guide sliding tubes do not extend to the arch erection area at the front end of the platform, the side arches tend to retract inward due to gravity. Therefore, when the folding arch frame is transferred from the front end of the platform to the arch erection area at the front end, the folding arch frame will naturally retract inward, making subsequent arch erection construction inconvenient. Utility Model Content

[0004] The purpose of this utility model is to provide a tunnel construction integrated machine with a guiding structure, which can guide the side arches of the arch frame at both ends of the platform, thereby effectively improving the stability of the arch frame transportation.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following solution:

[0006] A tunnel construction machine with a guiding structure includes a platform. The platform has guide members on its sides to facilitate the movement of the side arches. These guide members extend from the rear end to the front end of the platform, and an extension structure extending to the arch area is also provided at the front end. A lifting mechanism for lifting the arch frame is located at the rear end of the platform, and a transfer device for clamping the arch frame and transporting it from the rear end to the front end is located at the top end. Guide members for guiding the side arches of the arch frame are located on both sides of the platform. The rear end of the guide members is located between the rear end of the lifting mechanism and the platform, and an extension structure is provided on the section of the guide members outside the front end of the platform. The lifting mechanism and transfer device utilize existing technologies commonly found on platforms and will not be elaborated upon. Their function is to support the side arches of the arch frame during the transfer of the arch frame from the front end of the platform to the tunnel face, effectively preventing swaying of the side arches and ensuring smooth installation.

[0007] Furthermore, the guide members are in the shape of round or square tubes, and the guide members on the left and right sides of the platform are symmetrically arranged with the platform as the center, and the guide members are parallel to the bottom end of the platform. Their function is that, through the symmetrical design of the guide members on the left and right sides of the platform, they can provide the same limiting effect on both sides of the side arch; and through the design of the guide members being parallel to the bottom end of the platform, the side arch remains stable during transport from back to front.

[0008] Furthermore, the guide includes a front guide tube and a rear guide tube, with the rear guide tube having a higher height than the front guide tube.

[0009] Furthermore, the guide member has an expansion tube at its rear end, and the distance between the expansion tube and the platform gradually decreases from front to back. Its function is to allow the side arch to enter the expansion tube before it is fully expanded, and then allow the side arch to gradually expand along the expansion tube during forward transport.

[0010] Furthermore, the extension structure includes an extension tube nested at the front end of the guide member, the extension tube being coaxially arranged with the guide member. The nested arrangement of the guide member and the extension tube includes a state where the guide member is sleeved outside the extension tube and a state where the extension tube is sleeved outside the guide member. Its function is that, through the arrangement of the extension tube, the side arch of the arch frame can still be guided when the arch frame moves to the outside of the front end of the platform.

[0011] Furthermore, the extension tube is provided with a handle. The handle is ring-shaped and located on the side wall of the extension tube. Its function is to facilitate pulling the extension tube along its axial direction.

[0012] Furthermore, a diagonal brace is provided between the section of the guide member located outside the front end of the platform and the front end of the platform. The outer diameter of the extension tube is less than or equal to the inner diameter of the guide member. Multiple fixing holes are distributed axially on the extension tube. A through hole corresponding to the fixing hole is provided on the front side wall of the guide member. A pin is provided on the extension tube for simultaneously penetrating the through hole and the fixing hole. Its function is to enhance the structural strength of the section of the guide member located outside the front end of the platform by setting the diagonal brace; and to fix the length of the whole formed by the extension tube and the guide member by setting the fixing hole, through hole and pin.

[0013] Furthermore, the extension structure also includes a diagonal bracing telescopic rod disposed between the extension tube and the front end of the platform. The diagonal bracing telescopic rod includes an inner rod and an outer rod nested together. The diagonal bracing telescopic rod is hinged to the front end of the platform and to the extension tube. The inner rod and the outer rod are coaxially arranged, and the outer rod is cylindrical and sleeved outside the inner rod. Its function is to extend the overall length of the extension tube and the guide member by means of the nesting relationship between the extension tube and the guide member, as well as the nesting relationship between the inner rod and the outer rod, to adapt to different tunnel environments; and to maintain the structural strength of the extension tube while it is being pulled out by the diagonal bracing telescopic rod.

[0014] Furthermore, the guide member has a chamfer on its outer edge facing the extension tube. This chamfer facilitates the transition of the arch frame from the guide member to the extension tube.

[0015] Furthermore, both the inner and outer rods are provided with evenly spaced circular holes along the axial direction. The spacing between any two adjacent circular holes on the inner rod is the same as the spacing between any two adjacent circular holes on the outer rod. The diagonal brace telescopic rod is provided with a pin for simultaneously passing through the circular holes on both the inner and outer rods. Its function is to fix the length of the diagonal brace telescopic rod through the design of the circular holes and the pin.

[0016] Furthermore, the guide member is connected to the platform by reinforcing ribs, and a connecting plate is connected between every two adjacent reinforcing ribs. The top surface of the reinforcing ribs and the top surface of the connecting plate are on the same horizontal plane. The function of these ribs and connecting plates is to allow workers to walk on them when the arch frame is not being moved, so as to easily check the working conditions on both sides of the platform.

[0017] The beneficial effects of this utility model are:

[0018] 1. By extending the structure, the side arches of the arch frame can be supported during the transfer of the arch frame from the front end of the platform to the working face, effectively preventing the side arches from swaying and ensuring the smooth progress of the installation process.

[0019] 2. By setting up the expansion tube, the side arch can be allowed to enter the expansion tube before it is fully expanded, and then the side arch can gradually expand along the expansion tube during the forward transportation process.

[0020] 3. By setting up the extension tube, the side arch of the arch frame can still be guided when the arch frame moves to the front end of the platform. By setting up the diagonal bracing telescopic rod, the structural strength of the extension tube can be enhanced.

[0021] 4. The addition of reinforcing ribs and connecting plates allows workers to walk on the reinforcing ribs and connecting plates when the arch frame is not being moved, making it easier to check the working conditions on both sides of the platform. Attached Figure Description

[0030] Example 1

[0031] A tunnel construction integrated machine with a guiding structure, such as Figure 1 As shown, the system includes a platform 1. The side of the platform 1 is provided with a guide 2 to facilitate the movement of the side arch. The guide 2 extends from the rear end of the platform to the front end of the platform 1. An extension structure extending to the arch area is also provided at the front end of the platform 1. A lifting mechanism 18 for lifting the arch frame is provided at the rear end of the platform 1. A transfer device 19 for clamping the arch frame and transporting it from the rear end to the front end of the platform 1 is provided at the top end of the platform 1. Guide members 2 for guiding the side arches of the arch frame are provided on both the left and right sides of the platform 1. The rear end of the guide member 2 is located between the rear end of the lifting mechanism 18 and the platform 1. An extension structure is provided on the section of the guide member 2 outside the front end of the platform 1. The lifting mechanism 18 and the transfer device 19 both use common existing technologies common to the platform 1 and will not be described in detail. Their function is that, through the design of the extension structure, the side arches of the arch frame can be supported during the transfer of the arch frame from the front end of the platform 1 to the working face, effectively preventing the side arches from swaying and ensuring the smooth progress of the installation process.

[0032] Specifically, such as Figure 1 As shown, the guide member 2 is in the shape of a cylindrical tube. The guide members 2 on the left and right sides of the platform 1 are symmetrically arranged with the platform 1 as the center, and the guide members 2 are parallel to the bottom end of the platform 1. Its function is that, through the symmetrical design of the guide members 2 on the left and right sides of the platform 1, it can play the same limiting role on the left and right sides of the side arch; through the design of the guide members 2 being parallel to the bottom end of the platform 1, it can keep the side arch stable during the transportation process from back to front.

[0033] Specifically, such as Figure 1 As shown, the guide 2 includes a front guide tube 11 and a rear guide tube 12, with the height of the rear guide tube 12 being higher than the height of the front guide tube 11.

[0034] Specifically, such as Figure 1As shown, the guide member 2 has an expansion tube 3 at its rear end, and the distance between the expansion tube 3 and the platform 1 gradually decreases from front to back. Its function is to allow the side arch to enter the expansion tube 3 before it is fully expanded, and then allow the side arch to gradually expand along the expansion tube 3 during the forward transportation process.

[0035] Specifically, such as Figure 2 As shown, the extension structure includes an extension tube 4 nested at the front end of the guide member 2, and the extension tube 4 is coaxially arranged with the guide member 2. The nested arrangement of the guide member 2 and the extension tube 4 includes a state where the guide member 2 is sleeved outside the extension tube 4 and a state where the extension tube 4 is sleeved outside the guide member 2. Its function is that, through the arrangement of the extension tube 4, it can still guide the side arch of the arch frame when the arch frame moves to the front end of the platform 1.

[0036] Specifically, such as Figure 2 As shown, the extension tube 4 is provided with a handle 15. The handle 15 is arranged in a ring on the side wall of the extension tube 4. Its function is to facilitate pulling the extension tube 4 along its axial direction.

[0037] Specifically, such as Figure 2 As shown, a diagonal brace 16 is provided between the section of the guide member 2 located outside the front end of the platform 1 and the front end of the platform 1. The outer diameter of the extension tube 4 is less than or equal to the inner diameter of the guide member 2. Multiple fixing holes are distributed axially on the extension tube 4. A through hole corresponding to the fixing hole is provided on the front side wall of the guide member 2. A pin 17 is provided on the extension tube 4 to pass through both the through hole and the fixing hole. Its function is to enhance the structural strength of the section of the guide member 2 located outside the front end of the platform 1 by setting the diagonal brace 16; and to fix the length of the whole formed by the extension tube 4 and the guide member 2 by setting the fixing hole, the through hole and the pin 17.

[0038] Specifically, such as Figure 2 As shown, a reinforcing rib 13 connects the guide member 2 to the platform 1.

[0039] The working principle of this embodiment is explained as follows: When the arch frame is lifted by the lifting device, the side arches of the arch frame gradually open. When the distance between the two side arches is greater than the minimum distance between the two expansion pipes 3, the arch frame is clamped by the transfer device 19 and moved from the rear of the trolley 1 to the front of the trolley 1. When the arch frame passes the expansion pipe 3, the side arches move along the expansion pipe 3 and gradually expand outward. Then the arch frame is transported to the front of the trolley 1 along the guide pipe 2 and the extension pipe 4.

[0040] When the arch frame needs to be transported to a deeper part of the tunnel, take out the pin 17, pull the extension tube 4 outward, and when the extension tube 4 is pulled out to a suitable length and the fixing hole coincides with the through hole, insert the pin 17 to fix it.

[0041] Example 2

[0042] A tunnel construction integrated machine with a guiding structure, such as Figure 3 As shown, the system includes a platform 1. A lifting mechanism 18 for lifting the arch frame is located at the rear end of the platform 1. A transfer device 19 for clamping the arch frame and transporting it from the rear end to the front end of the platform 1 is located at the top end of the platform 1. Guide members 2 for guiding the side arches of the arch frame are located on both sides of the platform 1. The rear end of the guide member 2 is located between the rear end of the lifting mechanism 18 and the platform 1. An extension structure is provided on the section of the guide member 2 outside the front end of the platform 1. The lifting mechanism 18 and the transfer device 19 both use common existing technologies commonly found on the platform 1, and will not be described in detail. Their function is that, through the design of the extension structure, the side arches of the arch frame can be supported during the transfer of the arch frame from the front end of the platform 1 to the working face, effectively preventing the side arches from swaying and ensuring the smooth progress of the installation process.

[0043] Specifically, such as Figure 3 As shown, the guide member 2 is in the shape of a cylindrical tube. The guide members 2 on the left and right sides of the platform 1 are symmetrically arranged with the platform 1 as the center, and the guide members 2 are parallel to the bottom end of the platform 1. Its function is that, through the symmetrical design of the guide members 2 on the left and right sides of the platform 1, it can play the same limiting role on the left and right sides of the side arch; through the design of the guide members 2 being parallel to the bottom end of the platform 1, it can keep the side arch stable during the transportation process from back to front.

[0044] Specifically, such as Figure 3 As shown, the guide 2 includes a front guide tube 11 and a rear guide tube 12, with the height of the rear guide tube 12 being higher than the height of the front guide tube 11.

[0045] Specifically, such as Figure 3 As shown, the guide member 2 has an expansion tube 3 at its rear end, and the distance between the expansion tube 3 and the platform 1 gradually decreases from front to back. Its function is to allow the side arch to enter the expansion tube 3 before it is fully expanded, and then allow the side arch to gradually expand along the expansion tube 3 during the forward transportation process.

[0046] Specifically, such as Figure 4 As shown, the extension structure includes an extension tube 4 nested at the front end of the guide member 2, and the extension tube 4 is coaxially arranged with the guide member 2. The nested arrangement of the guide member 2 and the extension tube 4 includes a state where the guide member 2 is sleeved outside the extension tube 4 and a state where the extension tube 4 is sleeved outside the guide member 2. Its function is that, through the arrangement of the extension tube 4, it can still guide the side arch of the arch frame when the arch frame moves to the front end of the platform 1.

[0047] Specifically, such as Figure 4As shown, the extension structure also includes a diagonal telescopic rod 5 located between the extension tube 4 and the front end of the platform 1. The diagonal telescopic rod 5 includes an inner rod 6 and an outer rod 7 nested together. The diagonal telescopic rod 5 is hinged to the front end of the platform 1 and to the extension tube 4. The inner rod 6 and the outer rod 7 are coaxially arranged, and the outer rod 7 is cylindrical and sleeved outside the inner rod 6. Its function is to extend the overall length of the extension tube 4 and the guide member 2 by means of the nesting relationship between the extension tube 4 and the guide member 2, as well as the nesting relationship between the inner rod 6 and the outer rod 7, to adapt to different tunnel environments; and to maintain the structural strength of the extension tube 4 while it is being pulled out by the diagonal telescopic rod 5.

[0048] Specifically, such as Figure 4 As shown, the guide member 2 has a chamfer 8 on its outer edge facing the extension tube 4. The function of the chamfer 8 is to facilitate the transition of the arch frame from the guide member 2 to the extension tube 4.

[0049] Specifically, such as Figure 4 As shown, the inner rod 6 and the outer rod 7 each have evenly spaced circular holes 9 along their axial direction. The spacing between any two adjacent circular holes 9 on the inner rod 6 is the same as the spacing between any two adjacent circular holes 9 on the outer rod 7. The diagonal bracing telescopic rod 5 is provided with a pin 10 for simultaneously passing through the circular holes 9 on both the inner rod 6 and the outer rod 7. Its function is to fix the length of the diagonal bracing telescopic rod 5 through the design of the circular holes 9 and the pin 10.

[0050] Specifically, such as Figure 3 As shown, a reinforcing rib 13 connects the guide member 2 to the platform 1, and a connecting plate 14 connects every two adjacent reinforcing ribs 13. The top surface of the reinforcing rib 13 and the top surface of the connecting plate 14 are on the same horizontal plane. The function of the reinforcing ribs 13 and connecting plates 14 is to allow workers to walk on them when the arch frame is not being moved, so as to easily check the working conditions on both sides of the platform 1.

[0051] The working principle of this embodiment is explained as follows: When the arch frame is lifted by the lifting device, the side arches of the arch frame gradually open. When the distance between the two side arches is greater than the minimum distance between the two expansion tubes 3, the arch frame is clamped by the transfer device 19 and moved from the rear of the platform 1 to the front of the platform 1. When the arch frame passes the expansion tube 3, the side arches move along the expansion tube 3 and gradually expand outward. Then the arch frame is transported to the front of the platform 1 along the guide 2 and the extension tube 4.

[0052] When the arch frame needs to be transported to a deeper part of the tunnel, take out the pin 10, pull the extension tube 4 outward, and at the same time move the inner rod 6 outward from the outer rod 7. When the round hole 9 on the inner rod 6 and the outer rod 7 overlap again, insert the pin 10 to fix it.

[0053] The remaining structure and principle are the same as in Example 1.

[0054] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way.
