Description

Technical Field

[0001] This utility model relates to the field of tunnel construction technology, and in particular to an intelligent control platform vehicle for the central trench of a tunnel. Background Technology

[0002] The tunnel center ditch, also known as the tunnel center drainage ditch, is a facility used for drainage at the center of the tunnel. Currently, it is constructed by directly casting concrete into shape using an inverted arch filling method. Existing tunnel center ditch construction methods involve pouring concrete using formwork or scaffolding, including two specific construction methods: formwork splicing or integral scaffolding.

[0003] 1) The template splicing method relies on manual splicing of the templates and then the support work is done; however, the connection between manual measurement, template installation and concrete pouring is not smooth, which can easily lead to deviations in the trench alignment; in addition, environmental factors such as poor ventilation and insufficient lighting in the tunnel increase the risk to personnel; the template construction process makes it difficult to achieve real-time monitoring and dynamic adjustment of trench geometric parameters.

[0004] 2) The integral formwork method means that the entire ditch formwork is made into an independent whole. This method does not require manual erection of the formwork each time, saving labor. However, it requires engineering vehicles such as excavators to assist in moving it each time. The formwork is dismantled by force, which can easily damage the already constructed concrete. At the same time, it can cause the formwork to deform easily, affecting subsequent construction. The integral formwork must be larger at the top and smaller at the bottom, and the construction quality does not meet the construction standards. Utility Model Content

[0005] This utility model provides an intelligent control platform vehicle for the central trench of a tunnel, which can solve the following problems existing in the prior art:

[0006] 1) The poor connection between the installation of formwork and concrete pouring in the formwork splicing method can easily lead to deviations in the trench line shape, and it is difficult to achieve real-time monitoring and dynamic adjustment of the trench geometric parameters in the formwork construction process; 2) The integral formwork method can make demolding more difficult, which can cause the formwork to be easily deformed and affect subsequent construction.

[0007] A smart tunnel central trench intelligent control platform vehicle includes a construction trolley installed in the central trench of the tunnel;

[0008] The construction trolley is equipped with a molding template assembly for concrete pouring.

[0009] The molding template assembly includes a bottom template, and side templates are symmetrically arranged on both sides of the bottom template. The side templates on both sides are rotatably connected to the bottom template. The bottom template and the side templates on both sides enclose the central trench of the tunnel to form a molding cavity for pouring and forming a concrete pouring layer.

[0010] The bottom template is also equipped with an adjustment module, which is used to synchronously drive the side templates on both sides to rotate in a direction that moves closer to each other or away from each other.

[0011] Preferably, the width of the top of the side templates on both sides is greater than the width of their bottom, and the overall structure of the molding template assembly is wider at the top and narrower at the bottom.

[0012] Preferably, several sets of longitudinal beams are evenly fixedly arranged on the bottom template, and a load-bearing frame is fixedly arranged on the longitudinal beams, with the adjustment module set on the load-bearing frame.

[0013] Preferably, the adjustment module includes a first hinge seat fixedly arranged on the support frame, and two sets of adjustment hydraulic cylinders are symmetrically arranged on the first hinge seat.

[0014] The side templates on both sides are respectively fixedly provided with second hinge seats, and the driving end of the adjusting hydraulic cylinder is rotatably connected to the second hinge seats.

[0015] Preferably, the adjustment module includes a hydraulic cylinder vertically fixed on the bottom template. The driving ends of the hydraulic cylinder are symmetrically provided with adjustment rods that rotate through hinge seats. The other end of the adjustment rod is rotatably connected to the side template through the hinge seat.

[0016] Preferably, the construction trolley includes a frame body, and drive wheels are rotatably arranged on both sides of the frame body;

[0017] The vehicle frame is equipped with a servo motor, the output of which is connected to a speed reducer. The drive end of the speed reducer is connected to the drive wheel via a sprocket structure.

[0018] Preferably, the frame body is further provided with a height adjustment module for adjusting the height of the molding template assembly.

[0019] Preferably, the height adjustment module includes a lifting frame fixed to the vehicle frame body, a telescopic sleeve slidably sleeved on the lifting frame, a limiting frame fixedly arranged on one side of the telescopic sleeve, and the bottom template of the forming template assembly fixed to the limiting frame; wherein, the lifting frame and the telescopic sleeve are respectively provided with positioning pin holes, and the telescopic sleeve and the lifting frame are fixedly connected by the positioning pin holes and the positioning pin shaft.

[0020] Preferably, the height adjustment module includes a screw that is rotatably mounted on the frame body, the screw being fixed to the drive end of a servo drive device fixed on the frame body, a nut being spirally sleeved on the screw, a limit frame being fixedly mounted on one side of the nut, and the bottom template of the forming template assembly being fixed to the limit frame.

[0021] Preferably, a lifting cylinder is fixedly arranged at the bottom of the limiting frame, a support shaft is fixedly arranged at the drive end of the lifting cylinder, and a support seat for bearing is fixedly arranged at the bottom end of the support shaft.

[0022] This utility model provides an intelligent control platform vehicle for the central trench of a tunnel, which has the following beneficial effects:

[0023] 1) After the construction trolley of this utility model drives the forming template assembly to move to the central trench of the tunnel, the bottom template and side template of the forming template assembly form a forming cavity for concrete pouring by enclosing the central trench of the tunnel. This achieves the effect of automatic formwork assembly, eliminating the need for manual formwork assembly. Based on this, after the concrete is poured and hardened, during the demolding process, the side templates on both sides can be rotated at a certain angle by adjusting the module to move closer to each other, so that the side templates on both sides can be separated from the concrete on the side wall of the central trench of the tunnel. This achieves the effect of automatic demolding, eliminating the need for manual demolding or external equipment, resulting in higher demolding efficiency. At the same time, since the bottom template and side template of the forming template assembly maintain the same size and angle during each pouring process, the consistency of concrete pouring in each section of the central trench of the tunnel can be effectively guaranteed during the segmented pouring construction of the central trench, effectively improving the construction quality.

[0024] 2) In this utility model, after the height of the molding template assembly is adjusted, in order to ensure the support of the molding template assembly during the pouring process, a lifting cylinder is fixedly arranged at the bottom of the limiting frame. A support shaft is fixedly arranged at the drive end of the lifting cylinder, and a support seat for bearing is fixedly arranged at the bottom end of the support shaft. In the initial state, the support shaft of the lifting cylinder is in a retracted state. After the height of the molding template assembly is adjusted, this embodiment can drive the support shaft to descend through the lifting cylinder so that the support seat at the bottom end of the support shaft abuts against the bottom of the tunnel center trench, thereby achieving the effect of bearing the limiting frame and the molding template assembly, and further improving the stability of the molding template assembly and the limiting frame during pouring.

[0025] 3) In this utility model, when adjusting the height of the forming template assembly, the construction personnel first adjust the telescopic sleeve to slide on the lifting frame. The telescopic sleeve synchronously drives the forming template assembly to rise and fall. After the height of the forming template assembly is adjusted, the construction personnel lock and fix the positioning pin hole on the telescopic sleeve with the positioning pin hole on the lifting frame through the positioning pin shaft, thereby achieving the effect of positioning and fixing the telescopic sleeve. Correspondingly, when it is necessary to adjust the height of the forming template assembly again, the positioning pin shaft can be removed to readjust the position of the telescopic sleeve on the lifting frame.

[0026] 4) The overall structure of the molding template assembly of this utility model is wider at the top and narrower at the bottom, so that the remaining space in the central trench of the tunnel during pouring is also wider at the top and narrower at the bottom, which makes it easier to remove the molding template assembly from the central trench of the tunnel and improves demolding efficiency.

[0035] The specific embodiments of this utility model are described in detail below, but it should be understood that the protection scope of this utility model is not limited to the specific embodiments.

[0036] Example 1

[0037] like Figures 1 to 3 As shown in the figure, the intelligent control platform vehicle for the central tunnel of this utility model includes a construction trolley 1 installed in the central tunnel 4; specifically, the construction trolley 1 of this embodiment can move along the length of the central tunnel 4 to facilitate the segmented pouring of the central tunnel 4.

[0038] As one embodiment of this example, the construction trolley 1 is equipped with a molding template assembly 3 for concrete pouring; it should be noted that when pouring the central trench 4 of the tunnel, the molding template assembly 3 can be moved into the central trench 4 of the tunnel by the construction trolley 1, and the outer side of the molding template assembly 3 and the central trench 4 of the tunnel form a molding cavity for pouring, so as to facilitate subsequent pouring.

[0039] Specifically, during the pouring process, the concrete is transported into the forming cavity and vibrated during the pouring process. After the concrete has hardened, the forming template assembly 3 can be removed from the central tunnel ditch 4. Then, the forming template assembly 3 is driven by the construction trolley 1 to continue moving along the central tunnel ditch 4 for a certain distance to carry out the next section of pouring.

[0040] Further explanation is needed; please refer to [the relevant source]. Figures 4-5 The molding template assembly 3 includes a bottom template 301, and side templates 302 are symmetrically arranged on both sides of the bottom template 301. The side templates 302 on both sides are rotatably connected to the bottom template 301. The bottom template 301 and the side templates 302 on both sides are enclosed with the tunnel central trench 4 to form a molding cavity for pouring and forming a concrete pouring layer 401.

[0041] The bottom template 301 is also equipped with an adjustment module, which is used to synchronously drive the side templates 302 on both sides to rotate in a direction that moves closer to each other or away from each other. It can be explained that after the construction trolley 1 drives the forming template assembly 3 to move to the tunnel center trench 4, the bottom template 301 and the side templates 302 of the forming template assembly 3 enclose the tunnel center trench 4 to form a forming cavity for concrete pouring. This achieves the effect of automatic formwork assembly, eliminating the need for manual formwork assembly. Based on this, when the concrete is poured and hardened, during the demolding process, the side templates 302 on both sides can be driven to rotate at a certain angle in a direction that moves closer to each other by adjusting the module, so that the side templates 302 on both sides can be separated from the concrete on the side wall of the tunnel center trench 4. This achieves the effect of automatic demolding, eliminating the need for manual demolding or external equipment, resulting in higher demolding efficiency.

[0042] Meanwhile, since the bottom template 301 and side template 302 of the molding template assembly 3 maintain the same size and angle during each pouring process, the pouring consistency of each section of concrete in the central tunnel 4 can be effectively guaranteed during the segmented pouring construction of the central tunnel 4, thus effectively improving the construction quality.

[0043] It should also be noted that this embodiment does not limit the length of concrete poured in the central trench 4 of the tunnel each time, as long as it meets the actual construction application requirements. For example, the length of the bottom formwork 301 and the side formwork 302 in this embodiment is 12 meters, so that when the molded formwork assembly 3 is poured in each section, a 12-meter-long concrete pouring layer 401 can be formed.

[0044] Example 2

[0045] Based on Example 1, please refer to Figure 4 After the pouring is completed and the concrete has hardened, in order to facilitate demolding, in this embodiment, the width of the top of the side formwork 302 on both sides is greater than the width of its bottom, and the overall structure of the forming formwork assembly 3 is wider at the top and narrower at the bottom. It can be explained that, since the overall structure of the forming formwork assembly 3 is wider at the top and narrower at the bottom, the remaining space in the tunnel center trench 4 during pouring is also wider at the top and narrower at the bottom, which makes it easier to remove the forming formwork assembly 3 from the tunnel center trench 4 and improves the demolding efficiency.

[0046] In addition, you can refer to Figure 4 Several sets of longitudinal beams 304 are evenly fixed on the bottom template 301, and a bearing frame 303 is fixed on the longitudinal beams 304. The adjustment module is set on the bearing frame 303. Specifically, in this embodiment, the bottom template 301 and the adjustment module are supported by the longitudinal beams 304 and the bearing frame 303 to enhance the rigidity of the skeleton of the molded template assembly 3 and ensure its stability during the concrete pouring process.

[0047] In one embodiment of this invention, the adjustment module includes a first hinge seat 305 fixedly mounted on the support frame 303. Two sets of adjusting hydraulic cylinders 306 are symmetrically arranged on the first hinge seat 305. Second hinge seats 307 are fixedly mounted on the side templates 302 on both sides respectively. The driving end of the adjusting hydraulic cylinder 306 is rotatably connected to the second hinge seat 307. It can be noted that in this embodiment, when adjusting the angle of the side templates 302 on both sides, the adjusting hydraulic cylinders 306 on both sides can be activated simultaneously. The adjusting hydraulic cylinders 306 drive the side templates 302 on both sides to rotate on the bottom template 301, thereby realizing the angle adjustment of the side templates 302.

[0048] In another embodiment, the adjustment module includes a hydraulic cylinder vertically fixed on the bottom template 301. The driving ends of the hydraulic cylinders are symmetrically arranged with adjusting rods that rotate through hinge seats. The other ends of the adjusting rods are rotatably connected to the side templates 302 through the hinge seats. It can be noted that this embodiment can also achieve the effect of synchronous angle adjustment of the two side templates 302 by setting a set of vertically arranged hydraulic cylinders. Specifically, during the extension and retraction process, the driving ends of the vertically arranged hydraulic cylinders can directly drive the two side templates 302 to rotate synchronously through the adjusting rods.

[0049] Please refer to Figure 1 , Figure 3 and Figure 6 To drive the construction trolley 1 along the central tunnel ditch 4, the construction trolley 1 includes a frame body 101. Drive wheels 102 are rotatably arranged on both sides of the frame body 101. A servo motor 103 is fixedly arranged on the frame body 101. The output end of the servo motor 103 is connected to a reducer 104. The drive end of the reducer 104 is connected to the drive wheels 102 through a sprocket structure 105. It can be noted that in this embodiment, when driving the construction trolley 1 along the central tunnel ditch 4, the servo motor 103 can be started. The servo motor 103 drives the sprocket structure 105 through the reducer 104. The sprocket structure 105 can synchronously drive the drive wheels 102 to roll, thereby driving the construction trolley 1 to move along the central tunnel ditch 4.

[0050] Please refer to Figures 1-3 In order to adjust the height of the molding template assembly 3 to match the pouring height of the tunnel center trench 4, in this embodiment, the frame body 101 is also provided with a height adjustment module for adjusting the height of the molding template assembly 3. Specifically, after the construction trolley 1 moves to the construction position, the molding template assembly 3 can be driven to rise and fall in the vertical direction through the height adjustment module to adjust the height of the molding template assembly 3 to match the height of the tunnel center trench 4, so as to facilitate pouring.

[0051] In one embodiment of this invention, the height adjustment module includes a lifting frame 2 fixed to the vehicle frame body 101. A telescopic sleeve 202 is slidably sleeved on the lifting frame 2, and a limiting frame 203 is fixedly arranged on one side of the telescopic sleeve 202. The bottom template 301 of the forming template assembly 3 is fixed to the limiting frame 203. Positioning pin holes 201 are correspondingly provided on the lifting frame 2 and the telescopic sleeve 202. The telescopic sleeve 202 and the lifting frame 2 are fixedly connected through the positioning pin holes 201 and the positioning pin shaft. It can be noted that when the construction personnel adjust the height of the forming template assembly 3... When adjusting the height, first adjust the telescopic sleeve 202 to slide on the lifting frame 2. The telescopic sleeve 202 synchronously drives the forming template assembly 3 to rise and fall. After the height of the forming template assembly 3 is adjusted, the construction personnel lock and fix the positioning pin hole 201 on the telescopic sleeve 202 with the positioning pin hole 201 on the lifting frame 2 through the positioning pin shaft, thereby achieving the effect of positioning and fixing the telescopic sleeve 202. Correspondingly, when it is necessary to adjust the height of the forming template assembly 3 again, the positioning pin shaft can be removed to readjust the position of the telescopic sleeve 202 on the lifting frame 2.

[0052] In another embodiment of this invention, the height adjustment module includes a screw rotatably mounted on the frame body 101. The screw is fixed to the drive end of a servo drive device fixed on the frame body 101. A nut is screwed onto the screw, and a limit frame 203 is fixedly mounted on one side of the nut. The bottom template 301 of the forming template assembly 3 is fixed to the limit frame 203. It can be noted that in this embodiment, when adjusting the height of the forming template assembly 3, a servo drive device can be used to drive the screw to rotate. During the movement of the nut on the screw, the forming template assembly 3 can be driven to rise and fall synchronously. When using the height adjustment module of this embodiment to drive the forming template assembly 3 to rise and fall, no manual adjustment is required, and fully automated operation can be achieved, making the operation more convenient.

[0053] As a further embodiment, in order to improve the stability of the connection between the limiting frame 203 and the forming template assembly 3, reinforcing rods 204 are also fixedly arranged on both sides of the limiting frame 203. The reinforcing rods 204 and the limiting frame 203 form a triangular support structure to further improve the connection rigidity between the limiting frame 203 and the bottom template 301.

[0054] It should also be noted that, after the height of the molding template assembly 3 is adjusted, in order to ensure the support of the molding template assembly 3 during the pouring process, in this embodiment, please refer to... Figure 1 The bottom of the limiting frame 203 is also fixedly provided with a lifting cylinder 5, the drive end of the lifting cylinder 5 is fixedly provided with a support shaft 501, and the bottom end of the support shaft 501 is fixedly provided with a support seat 502 for bearing. It can be explained that in the initial state, the support shaft 501 of the lifting cylinder 5 is in a retracted state. After the height of the forming template assembly 3 is adjusted, this embodiment can drive the support shaft 501 to descend through the lifting cylinder 5 so that the support seat 502 at the bottom end of the support shaft 501 abuts against the bottom of the tunnel center trench 4, thereby achieving the effect of bearing the limiting frame 203 and the forming template assembly 3, and further improving the stability of the forming template assembly 3 and the limiting frame 203 during pouring.

[0055] For further details, please refer to Figures 1-2 as well as Figures 5-6 The bottom of the formed concrete pouring layer 401 is embedded with a lower base plate 404, and an upper cover plate 402 is embedded on the lower base plate 404. The lower base plate 404 has a first semi-circular groove 403, and the bottom of the upper cover plate 402 has a second semi-circular groove 406 corresponding to the first semi-circular groove 403. The first semi-circular groove 403 and the second semi-circular groove 406 together form a circular groove for the drainage pipe 405 to pass through. It can be noted that after the concrete pouring layer 401 has hardened and formed, the lower base plate 404, the drainage pipe 405 and the upper cover plate 402 can be sequentially set in the concrete pouring layer 401, and the drainage pipe 405 is used to drain the tunnel.

[0058] S2. The height adjustment module drives the forming template assembly 3 to rise and fall vertically to adjust the height of the forming template assembly 3 to match the height of the tunnel center trench 4.

[0059] S3. After the degree adjustment is completed, the lifting cylinder 5 drives the support shaft 501 to descend, so that the support seat 502 at the bottom of the support shaft 501 abuts against the bottom of the tunnel center trench 4, so as to support the limit frame 203 and the forming template assembly 3.

[0060] S4. The bottom template 301 and side template 302 of the forming template assembly 3 are enclosed with the central trench 4 of the tunnel to form a forming cavity for concrete pouring.
