Description

Technical Field

[0001] This invention relates to the field of building construction technology, and in particular to an automatic installation mechanism for formwork components used in the construction of corbel linings. Background Technology

[0002] After tunnel excavation, the original balance of the surrounding strata is disrupted, causing tunnel deformation or collapse. To protect the stability of the surrounding rock and ensure traffic safety, the tunnel must have a sufficiently strong support structure, namely the tunnel lining. During construction, corbel structures are typically cast onto the tunnel lining to transfer loads at the joints in the middle of the lining.

[0003] When constructing the corbel structure, the formwork components need to be installed onto the corbel of the lining first. The conventional method is for construction workers to climb a hydraulic trolley and then install the formwork onto the corbel. However, when this method is applied to tunnels with large structures, the large tunnel space and the height of the corbel structure lead to high construction height, high construction difficulty, and a high risk factor. At the same time, manual installation is also very complicated, inefficient, and wastes a lot of manpower. Furthermore, when using manual formwork installation, errors can easily occur in the installation angle of the support position, resulting in low installation accuracy, which also affects the construction accuracy and efficiency of the corbel. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides an automatic installation mechanism for formwork components used in the construction of corbel linings, thereby solving the problems of complex installation operations and low efficiency when formwork is installed manually.

[0005] To achieve the above objectives, the basic solution of the present invention is as follows: an automatic installation mechanism for template components for lining corbel construction, including a first lining template that fits against the upper side of the corbel structure and the lining sidewall, and a second lining template that fits against the vertical side and lower side of the corbel structure and the lining sidewall, further including a first control unit for controlling the vertical or horizontal movement of the first lining template and a second control unit for controlling the vertical or horizontal movement of the second lining template, wherein a hinge unit is provided between the side of the first lining template close to the second lining template and the second lining template, and both the first control unit and the second control unit are connected to a hydraulic control system controlled by a hydraulic trolley.

[0006] The technical principle of this invention is as follows: When installing the first and second lining templates at the corbel, a hydraulic control system controls the first and second control units. The first control unit controls the vertical or horizontal movement of the first lining template, so that the first lining template is installed on the upper side of the corbel structure and opposite to the sidewall of the tunnel. At the same time, the second control unit controls the vertical or horizontal movement of the second lining template, so that the second lining template automatically fits into the vertical and lower sides of the corbel structure. During this process, the hinge unit allows the first and second lining templates to move together, so that the relative position between the first and second lining templates is accurately maintained, which facilitates the precise placement of the first and second lining templates at the corbel structure.

[0007] The movement of the first and second lining templates is automated through the first control unit, the second control unit, and the hydraulic control system. This eliminates the need for manual installation of the first and second lining templates onto the corbel structure, making construction more convenient and faster, and improving installation accuracy and construction precision. The above method also reduces the risks during construction, enabling safer construction.

[0008] Furthermore, the hydraulic trolley is equipped with several third lining templates that fit against the tunnel sidewalls, as well as a third control unit connected to the third lining templates.

[0009] With the above configuration, the third lining template can cooperate with the first and second lining templates to form the lining construction position inside the tunnel, which facilitates the rapid forming of the lining.

[0010] Furthermore, the first control unit includes a first lead screw, a second lead screw, a third hydraulic telescopic rod, and a hinge block located between the second lead screw and the third hydraulic telescopic rod. The third hydraulic telescopic rod is connected to the hydraulic control system. The third control unit includes a fourth lead screw, one end of which is hinged to the hydraulic trolley, and the other end of which is hinged to the third lining template. One end of the first lead screw is hinged to the hydraulic trolley, and the other end of the first lead screw is hinged to the first lining template. The hinge block is rotatably mounted on the third lining template. The hinge block is located on the side of the fourth lead screw adjacent to the first lead screw, close to the third lining template. One end of the second lead screw is hinged to the hydraulic trolley, and the other end of the second lead screw is located on the side of the fourth lead screw adjacent to the first lead screw, away from the first lead screw. The second lead screw is hinged to the hinge block, and the other end of the hinge block is hinged to one end of the third hydraulic telescopic rod. The other end of the third hydraulic telescopic rod is hinged to the first lining template, and the connection between the first lining template and the third hydraulic telescopic rod is close to the connection between the first lead screw and the first lining template.

[0011] With the above settings, the lengths of the first, second, and fourth lead screws are pre-adjusted according to the position of the first lining template. When the hydraulic trolley is started, the first lead screw can horizontally push the first lining template to move. At the same time, after the second lead screw extends, it can move synchronously with the first lead screw, the fourth lead screw, and the hinge block to push the third hydraulic telescopic rod towards the inner wall of the tunnel. The extended third hydraulic telescopic rod can cooperate with the extension direction of the second lead screw to press the first lining template down and fit it against the upper side of the corbel structure, so that the installation of the first lining template is accurate.

[0012] Furthermore, the second control unit includes a fifth hydraulic telescopic rod, a sixth hydraulic telescopic rod, and a sliding abutment block that abuts against the vertical surface of the second lining template. Both the fifth and sixth hydraulic telescopic rods are connected to the hydraulic control system. One end of the fifth hydraulic telescopic rod is hinged to the upper side of the sliding abutment block, and the other end of the fifth hydraulic telescopic rod is hinged to the hinge joint between the first lead screw and the first lining template. The sixth hydraulic telescopic rod is horizontally arranged, with one end of the sixth hydraulic telescopic rod hinged to the lower side of the sliding abutment block and the other end of the sixth hydraulic telescopic rod hinged to the hydraulic trolley.

[0013] With the above setup, after the end of the sixth hydraulic telescopic rod extends, it drives the fifth hydraulic telescopic rod to rotate relative to the first lead screw and sliding sleeve, thereby pressing the vertical side of the second lining template against the inner wall of the tunnel, thus achieving horizontal pressing installation of the second lining template.

[0014] Furthermore, the sliding abutment block includes a fixed block and a sliding sleeve sleeved outside the fixed block. Several limiting strips are provided on the outer wall of the fixed block along the horizontal axis. The limiting strips abut against the inner wall of the sliding sleeve. Several sliding blocks that can slide horizontally between two adjacent limiting strips are provided between the sliding sleeve and the fixed block. The ends of the fifth hydraulic telescopic rod and the sixth hydraulic telescopic rod are hinged to the outer wall of the sliding sleeve. The end of the sliding sleeve away from the fixed block abuts against the second lining template. The end of the fixed block away from the sliding sleeve is fixedly connected to the hydraulic trolley.

[0015] With the above settings, the sliding sleeve can slide along the surface of the fixed block through the cooperation between the sliding block and the limiting strip, so that the end of the sliding sleeve can accurately and stably abut against the second lining template, thereby stably limiting the vertical side of the second lining template. At the same time, the setting of the fixed block can also ensure the stable installation of the sliding sleeve.

[0016] Furthermore, the hinge unit includes a connecting block and a hinge. The connecting block is horizontally fixedly installed on the side of the first lining template close to the second lining template. The end of the connecting block away from the first lining template is fixedly connected to the hinge side. The hinge is fixedly connected to the side of the second lining template close to the first lining template.

[0017] With the above configuration, the connecting block and hinge can stably limit the relative positional accuracy between the first lining template and the second lining template, thereby facilitating the interlocking of the positions of the first lining template and the second lining template and improving the overall installation accuracy of the first lining template and the second lining template.

[0018] Furthermore, the sliding block is a roller, and the rollers are divided into two groups. One group of rollers is located on the upper side of the fixed block and opposite to the fifth hydraulic telescopic rod, while the other group of rollers is located on the lower side of the fixed block and opposite to the sixth hydraulic telescopic rod.

[0019] The rollers make the movement of the sliding sleeve on the fixed block smoother and make it easier to control the relative position between the sliding sleeve and the second lining template.

[0020] Furthermore, the rollers are all rotatably mounted inside the side wall of the sliding sleeve.

[0021] With the above settings, the fit between the roller, the sliding sleeve, and the fixed block is tighter, and the horizontal movement of the sliding sleeve is more stable.

[0022] Furthermore, a groove is provided on the vertical sidewall of the second lining template away from the inner wall of the tunnel, and a protrusion that can be embedded in the groove is fixedly installed on one end of the sliding sleeve near the second lining template.

[0023] With the above configuration, when the sliding sleeve abuts against the outer wall of the second lining template, the protrusion can be embedded into the groove, making the installation between the sliding sleeve and the second lining template more tight. Attached Figure Description

Detailed Implementation

[0027] The technical solutions of the present invention will be further described below with reference to the accompanying drawings and embodiments.

[0028] This embodiment is basically as follows: Figure 1 and Figure 2 As shown, this embodiment of the invention proposes an automatic installation mechanism for template components used in the construction of tunnel lining corbels. The mechanism includes a first lining template 20 that adheres to the upper side of the corbel structure and the lining sidewall; a second lining template 40 that adheres to the vertical side and lower side of the corbel structure and the lining sidewall; a first control unit that controls the vertical or horizontal movement of the first lining template 20; and a second control unit that controls the vertical or horizontal movement of the second lining template 40. A hinge unit is provided between the first lining template 20 and the second lining template 40 on the side closest to the second lining template 40. Both the first and second control units are connected to a hydraulic control system controlled by a hydraulic trolley 10. The hydraulic trolley 10 is equipped with several third lining templates 60 that adhere to the tunnel sidewall and third control units connected to the third lining templates 60.

[0029] like Figure 2 As shown, the first control unit includes a first lead screw 201, a second lead screw 203, a third hydraulic telescopic rod 202, and a hinge block 204 located between the second lead screw 203 and the third hydraulic telescopic rod 202. The third hydraulic telescopic rod 202 is connected to the hydraulic control system. The third control unit includes a fourth lead screw 601, the right end of which is hinged to the hydraulic trolley 10, and the left end of which is hinged to the third lining template 60. The right end of the first lead screw 201 is hinged to the hydraulic trolley 10, and the left end of the first lead screw 201 is hinged to the first lining template 202. Hinged; one end of the second lead screw 203 is hinged to the hydraulic trolley 10, and the other end of the second lead screw 203 is located on the side of the fourth lead screw 601 adjacent to the first lead screw 201 away from the first lead screw 201. The second lead screw 203 is hinged to the hinge block 204, and the other end of the hinge block 204 is hinged to one end of the third hydraulic telescopic rod 202. The other end of the third hydraulic telescopic rod 202 is hinged to the first lining template 20, and the connection between the first lining template 20 and the third hydraulic telescopic rod 202 is close to the connection between the first lead screw 201 and the first lining template 20.

[0030] like Figure 2As shown, the second control unit includes a fifth hydraulic telescopic rod 401, a sixth hydraulic telescopic rod 402, and a sliding abutment block that abuts against the vertical surface of the second lining template 40. Both the fifth and sixth hydraulic telescopic rods 401 and 402 are connected to the hydraulic control system. The sliding abutment block includes a fixed block 501 and a sliding sleeve 502 fitted over the fixed block 501. Four limiting strips 503 are arranged along the horizontal axis on the outer wall of the fixed block 501, with two limiting strips 503 located on the upper side of the fixed block 501 and the other two on the lower side. The limiting strips 503 abut against the inner wall of the sliding sleeve 502. Several sliding blocks, which can slide horizontally between adjacent limiting strips 503, are provided between the sliding sleeve 502 and the fixed block 501. The sliding blocks are rollers 504, and each roller 504 is rotatably mounted on the sliding sleeve 502. Inside the side wall of the moving sleeve 502, several rollers 504 are divided into two groups. One group of rollers 504 is located between the two upper limiting strips 503, and the other group of rollers 504 is located between the two lower limiting strips 503. At the same time, the right end of the fifth hydraulic telescopic rod 401 is hinged to the upper side of the sliding sleeve 502, and the left end of the fifth hydraulic telescopic rod 401 is hinged to the hinge of the first lead screw 201 and the first lining template 20. The sixth hydraulic telescopic rod 402 is horizontally set. The left end of the sixth hydraulic telescopic rod 402 is hinged to the lower side of the sliding sleeve 502, and the right end of the sixth hydraulic telescopic rod 402 is hinged to the hydraulic trolley 10. The ends of the fifth hydraulic telescopic rod 401 and the sixth hydraulic telescopic rod 402 are hinged to the outer wall of the sliding sleeve 502. The left end of the sliding sleeve 502 abuts against the second lining template 40, and the right end of the fixing block 501 is welded to the hydraulic trolley 10.

[0031] like Figure 2 As shown, the hinge unit includes a connecting block 301 and a hinge 302. The connecting block 301 is horizontally welded to the lower right side of the first lining template 20. The right end of the connecting block 301 is fixedly connected to the upper side of the hinge 302 by bolts. The hinge 302 is fixedly connected to the upper side of the second lining template 40 by bolts.

[0032] In addition, such as Figure 2 As shown, the second lining template 40 has a groove on the vertical sidewall away from the tunnel inner wall, and a protrusion 505 that can be embedded in the groove is fixedly installed on one end of the sliding sleeve 502 near the second lining template 40.

[0033] In this embodiment, the automatic installation mechanism for the formwork assembly used in the construction of the lining corbel is used such that the hydraulic trolley 10 moves along the track inside the tunnel. When the hydraulic trolley 10 is aligned with the construction site of the lining, its movement stops. The lengths of the first lead screw 201, the second lead screw 203, and the fourth lead screw 601 are adjusted in advance according to the position of the first lining formwork 20. Then, the entire hydraulic trolley 10 is extended. At this time, the hydraulic trolley 10 controls the first control unit and the second control unit through the hydraulic control system, thereby controlling the third hydraulic telescopic rod 202. Both the fifth hydraulic telescopic rod 401 and the sixth hydraulic telescopic rod 402 extend, pushing the first lead screw 201, the second lead screw 203, and the third hydraulic telescopic rod 202 to move the first lining template 20 closer to the inner wall of the tunnel while moving downwards. The fourth lead screw 601 pushes the third lining template 60 closer to the inner wall of the tunnel and assembles it with the first lining template 20. The fifth hydraulic telescopic rod 401 and the sixth hydraulic telescopic rod 402 also simultaneously push the third lining template 60 closer to the corbel structure of the lining, and the third lining template 60 also assembles with the first lining template 20.

[0034] During the above process, the first lead screw 201 can horizontally push the first lining template 20 to move. Simultaneously, the extended second lead screw 203, together with the first lead screw 201, the fourth lead screw 601, and the hinge block 204, can push the third hydraulic telescopic rod 202 to move synchronously towards the tunnel inner wall. The extended third hydraulic telescopic rod 202, in coordination with the extension direction of the second lead screw 203, presses the first lining template 20 down, fitting it against the upper side of the corbel structure. At the same time, the end of the sixth hydraulic telescopic rod 402 extends, causing the fifth hydraulic telescopic rod 401 to rotate relative to the first lead screw 201 and the sliding sleeve 502, thereby pressing the vertical side of the second lining template 40 against the tunnel inner wall, achieving [the desired effect]. The second lining template 40 is horizontally pressed and installed. During this process, the connecting block 301 and the hinge 302 cooperate to facilitate the control of the gap between the first lining template 20 and the second lining template 40, which can effectively control the installation accuracy between the first lining template 20 and the second lining template 40. Throughout the process, there is no need for manual adjustment and installation of the positions of the first lining template 20 and the second lining template 40. It is only necessary to control the lengths of the first lead screw 201, the second lead screw 203, the third hydraulic telescopic rod 202, the fourth lead screw 601, the fifth hydraulic telescopic rod 401, and the sixth hydraulic telescopic rod 402, so that the installation of the first lining template 20, the second lining template 40, and the third lining template 60 is quick and convenient.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
