[0020] The using method of the self-propelled bridge building machine includes the following steps:

[0021] Step S1, after the casting of the previous section of the bridge main body is completed, adjust the setting position of the self-propelled main bracket;

[0022] Step S2, supply hydraulic pressure to the hydraulic lifting rod through an external hydraulic device to extend the output end of the hydraulic lifting rod. The extended output end of the hydraulic lifting rod contacts the bridge surface. During the continuous extension of the hydraulic lifting rod, the hydraulic lifting rod pushes the self-propelled main bracket in the reverse direction, causing the self-propelled main bracket to lift relative to the bridge surface;

[0023] Step S3, when the self-propelled main bracket is lifted, the second hydraulic push rod contracts. The contraction of the second hydraulic push rod drives the main bracket slide rail, causing the main bracket slide rail to slide along the support frame;

[0024] Step S4, after the main bracket slide rail slides into place, control the hydraulic lifting rod to retract. As the hydraulic lifting rod retracts, the main bracket slide rail contacts the bridge again, and fix the main bracket slide rail to the bridge surface through bolts;

[0025] Step S5, control the second hydraulic push rod to extend. The extended second hydraulic push rod pushes the main arm in the reverse direction, causing the main arm to move along the main bracket slide rail. The movement of the main arm synchronously drives the template angle adjustment part, the angle adjustment component, the bottom template adjustment component, the movable side form component, and the sliding inner form component to move;

[0026] Step S6, after the main arm reaches the predetermined position, pass the threaded connecting rod through the through hole preset on the bridge beam segment and thread it with the sliding connecting frame, and install the lifting bracket at the end of the threaded connecting rod;

[0027] Step S7, control the first hydraulic push rod to extend. The movable end of the first hydraulic push rod pushes the threaded connecting rod upward during the movement. The upward moving threaded connecting rod pulls the sliding connecting frame upward, and the template angle adjustment part connected to the sliding connecting frame moves upward under the drive of the sliding connecting frame;

[0028] Step S8, the support roller seat 1 at the end of the adjustment arm moves upward synchronously with the adjustment arm. At the same time, the end of the upward moving third hydraulic push rod contacts the bridge side wall before the adjustment arm. When the horizontal height of the adjustment arm reaches the preset height with the sliding connecting frame, control the third hydraulic push rod to extend. The extended third hydraulic push rod pushes the adjustment arm in the reverse direction, causing the adjustment arm to rotate relative to the sliding connecting frame around the rotating shaft until the set angle of the rotating adjustment arm meets the usage requirements, and the adjustment arm maintains the set angle;

[0029] Step S9, adjust the set angle of the bottom template. First, adjust the second threaded adjustment seat, and adjust the height of the pull rod connected to the first adjustment rod through the second threaded adjustment seat. The pull rod drives the connecting ring and the first adjustment rod connected to the connecting ring to be adjusted synchronously during the position adjustment. Then, adjust the first threaded adjustment seat, and adjust the height of the pull rod connected to the second adjustment rod through the first threaded adjustment seat. The pull rod drives the connecting ring and the second adjustment rod connected to the connecting ring to move synchronously during the position adjustment. Complete the angle setting of the bottom template by adjusting the height difference between the first adjustment rod and the second adjustment rod;

[0030] Step S10, after the setting angle of the bottom template is completed, the support roller seat 2 is controlled to work and extend, and during the extension process of the support roller seat 2, the side template bracket is pushed to make the side template bracket slide along the slideway, and during the sliding process, the side template bracket drives the side template to approach the bottom template, and when the outer wall of the side template contacts the side wall of the bottom template, the side template and the bottom template form a complete bottom template and side template;

[0031] Step S11, after the bottom mold and the side mold are set, the slide is manually pushed to slide along the inner mold slide rail, and the sliding slide drives the inner mold main support, the inner mold cross plate, the inner mold side plate, the inner mold auxiliary support, the hydraulic push rod five and the inner mold vertical plate to move synchronously. When the end of the slide contacts the end of the bridge and reaches the setting position, the slide is fixed at the setting position by bolt tightening, and the hydraulic push rod five is controlled to extend. During the extension process, the hydraulic push rod five pushes the inner mold auxiliary support to rotate around the rotation axis. During the rotation process, the inner mold auxiliary support drives the inner mold vertical plate from a deflected state to a vertical state. At this time, the inner mold cross plate, the inner mold side plate and the inner mold vertical plate form an inner mold;

[0032] Step S12, closing the bottom of the inner mold, after completing the closing of the bottom of the inner mold, pouring the beam end, after pouring is completed, repeating steps S1-S11 to pour the bridge beam ends one by one.

[0033] Compared with the prior art, the beneficial effects of the present invention are:

[0034] 1. The present invention provides a self-propelled main support, which includes a main arm, a side arm, a sliding connection frame, a threaded connecting rod, a lifting support and a hydraulic push rod 1. The hydraulic pressure is supplied to the hydraulic lifting rod by an external hydraulic device to extend the output end of the hydraulic lifting rod. The extended output end of the hydraulic lifting rod contacts the surface of the bridge. In the process of continuous extension of the hydraulic lifting rod, the hydraulic lifting rod pushes the self-propelled main support in the opposite direction to lift the self-propelled main support relative to the surface of the bridge. When the self-propelled main support is lifted, the hydraulic push rod 2 is retracted. The retracted hydraulic push rod 2 drives the main support slide rail to slide along the support frame. In this way, the self-propelled main support gradually moves along the bridge with the support of the completed bridge body. The requirement for the clearance height above the bridge is low, and the construction of the bridge with an upper span can be better adapted.

[0035] 2. The present invention is provided with the template angle adjustment part, which includes an adjustment arm, a support roller seat 1, a hydraulic push rod 3 and a reinforcing rod. During the upward movement of the adjustment arm, the end of the upward hydraulic push rod 3 contacts the side wall of the bridge before the adjustment arm. When the horizontal height of the adjustment arm reaches the preset height along with the sliding connection frame, the hydraulic push rod 3 extends, and the extended hydraulic push rod 3 reversely pushes the adjustment arm to rotate the adjustment arm relative to the sliding connection frame around the rotating shaft, thereby adjusting the setting angle. Through the rotation adjustment method, the adaptation to the under-span radian of the bridge can be realized, so as to complete the pouring of the bridge without adding additional molds.

[0036] 3. The present invention is provided with the bottom template adjustment component, which includes a first adjustment rod, a second adjustment rod, a connection ring and a pull rod. When adjusting the setting angle of the bottom template, first adjust the thread adjustment seat 2, and adjust the height of the pull rod connected to the first adjustment rod through the thread adjustment seat 2. During the position adjustment of the pull rod, the connection ring and the first adjustment rod connected to the connection ring are synchronously adjusted. Then adjust the thread adjustment seat 1, and adjust the height of the pull rod connected to the second adjustment rod through the thread adjustment seat 1. The connection ring and the second adjustment rod connected to the connection ring driven by the pull rod during the position adjustment move synchronously. The angle setting of the bottom template is completed by adjusting the height difference between the first adjustment rod and the second adjustment rod. The bottom template adjustment component, as a supplement to the template angle adjustment part, can further adapt to the under-span radian of the bridge; BRIEF DESCRIPTION OF THE DRAWINGS

[0048] The following further elaborates the present invention in combination with the accompanying drawings and embodiments on the above and other technical features and advantages of the present invention. However, the following embodiments are only the preferred embodiments of the present invention and not all of them.

[0049] Embodiment:

[0050] As Figure 1 - Figure 8 shown, the present invention provides a self-propelled bridge building machine, including a self-propelled main support 1, a template angle adjustment part 2, an angle adjustment component 3, a bottom template adjustment component 4, a mobile side mold assembly 5 and a sliding internal mold assembly 6;

[0051] The self-propelled main support 1 is arranged at the end of the bridge;

[0052] The template angle adjustment part 2 is installed below the end of the self-propelled main support 1 through a rotating shaft, and the template angle adjustment part 2 can rotate relative to the self-propelled main support 1 through the rotating shaft;

[0053] The angle adjustment component 3 is fixed to the end of the template angle adjustment part 2 by bolts;

[0054] The bottom template adjustment component 4 is installed between the angle adjustment component 3 and the template angle adjustment part 2, and the bottom template adjustment component 4 forms the bottom mold of the bridge;

[0055] The mobile side formwork assembly 5 is arranged between the interiors of two sets of formwork angle adjusting parts 2, and the two mobile side formwork assemblies 5 form the side formwork of the bridge.

[0056] The sliding inner formwork assembly 6 is arranged below the middle part of the self-propelled main support 1. The end of the sliding inner formwork assembly 6 is connected to the bottom of the angle adjusting assembly 3 and supported by the angle adjusting assembly 3. The sliding inner formwork assembly 6 forms the inner formwork of the bridge.

[0057] The self-propelled main support 1 includes a hydraulic lifting rod 17, a second hydraulic push rod 18, and a main support slide rail 19;

[0058] A support frame is arranged at the bottom of the middle section of the main arm 11. The hydraulic lifting rod 17 is arranged at the side position of the support frame. The second hydraulic push rod 18 is fixedly connected to the side of the support frame through a rotating shaft. The main support slide rail 19 is arranged inside the support frame. The main support slide rail 19 can move horizontally relative to the support frame. The middle part of the main support slide rail 19 is connected to the movable end of the second hydraulic push rod 18;

[0059] When adjusting the installation position of the self-propelled main support 1, an external hydraulic device supplies hydraulic pressure to the hydraulic lifting rod 17 to make the output end of the hydraulic lifting rod 17 extend. The extended output end of the hydraulic lifting rod 17 contacts the bridge surface. During the continuous extension of the hydraulic lifting rod 17, the hydraulic lifting rod 17 reversely pushes the self-propelled main support 1 to lift the self-propelled main support 1 relative to the bridge surface. As the self-propelled main support 1 is lifted, the second hydraulic push rod 18 contracts. The contracting second hydraulic push rod 18 drives the main support slide rail 19 to make the main support slide rail 19 slide along the support frame. After the main support slide rail 19 slides in place, control the hydraulic lifting rod 17 to retract. As the hydraulic lifting rod 17 retracts, the main support slide rail 19 contacts the bridge again. Fix the main support slide rail 19 to the bridge surface through bolts. Control the second hydraulic push rod 18 to extend. The extended second hydraulic push rod 18 reversely pushes the main arm 11 to make the main arm 11 move along the main support slide rail 19, realizing the adjustment of the installation position of the main arm 11;

[0060] The self-propelled main support 1 includes a main arm 11, a side arm 12, a sliding connection frame 13, a threaded connecting rod 14, a lifting support 15, and a first hydraulic push rod 16;

[0061] The main arm 11 is arranged at the end of the formed bridge. The side arm 12 is installed at the end of the main arm 11 through bolts. The sliding connection frame 13 is arranged at the end of the side arm 12. A vertical slideway is formed on the side of the sliding connection frame 13. The vertical slideway on the side of the sliding connection frame 13 is sleeved outside the end of the side arm 12. The sliding connection frame 13 forms a movable vertical connection structure with the side arm 12 through the vertical slideway. The threaded connecting rod 14 is threadedly connected inside the sliding connection frame 13. The upper end of the threaded connecting rod 14 passes through the main arm 11. The lifting bracket 15 is threadedly connected to the upper end of the threaded connecting rod 14, and the bottom end of the lifting bracket 15 abuts against the top of the main arm 11. The first hydraulic push rod 16 is arranged inside the lifting bracket 15, and the output end of the first hydraulic push rod 16 abuts against the top of the lifting bracket 15;

[0062] After the main arm 11 reaches the predetermined position, the threaded connecting rod 14 is passed through a through hole preset on the bridge beam section and threadedly connected to the sliding connection frame 13. Then the lifting bracket 15 is reinstalled at the end of the threaded connecting rod 14. The first hydraulic push rod 16 is controlled to extend. The movable end of the first hydraulic push rod 16 pushes the threaded connecting rod 14 upward during the movement. The upward threaded connecting rod 14 pulls the sliding connection frame 13 upward. The template angle adjusting part 2 connected to the sliding connection frame 13 moves upward under the drive of the sliding connection frame 13.

The other end of the reinforcing rod 24 is connected to the side wall of the main arm 11 through a universal joint;

[0065] During the upward movement of the adjusting arm 21, the first support roller seat 22 at the end of the adjusting arm 21 moves upward synchronously with the adjusting arm 21. At the same time, the end of the upward third hydraulic push rod 23 abuts against the side wall of the bridge before the adjusting arm 21. When the horizontal height of the adjusting arm 21 reaches the preset height with the sliding connection frame 13, the third hydraulic push rod 23 is controlled to extend. The extended third hydraulic push rod 23 reversely pushes the adjusting arm 21 to make the adjusting arm 21 rotate relative to the sliding connection frame 13 around the rotating shaft. When the set angle of the rotating adjusting arm 21 meets the use requirements, the third hydraulic push rod 23 stops extending. At this time, the adjusting arm 21 maintains the set angle;

[0066] Before the main arm 11 moves, control the retraction of the third hydraulic push rod 23. During the retraction of the third hydraulic push rod 23, the adjusting arm 21 rotates. During the rotation of the adjusting arm 21, the first support roller seat 22 abuts against the surface of the beam segment. When the main arm 11 starts to move, the cooperation between the sliding connection frame 13 and the adjusting arm 21 drives the adjusting arm 21 to move horizontally. During the horizontal movement, the first support roller seat 22 moves along the surface of the bridge, and the first support roller seat 22 serves as the support during the movement of the end of the adjusting arm 21.

[0067] The angle adjustment assembly 3 includes a horizontally arranged rod 31 and a second threaded adjustment seat 32.

A first threaded adjustment seat 25 is arranged at the middle position of the lower end of the adjusting arm 21. The pull rod 44 arranged on the first adjustment rod 41 is respectively connected to the first threaded adjustment seats 25 on two groups of adjusting arms 21. The bottom form adjustment assembly 4 further includes a bottom form support rod 45 and a bottom form 46. The bottom form support rod 45 is erected between the first adjustment rod 41 and the second adjustment rod 42. The bottom form 46 is laid on the surface of the bottom form support rod 45.

[0072] When adjusting the setting angle of the bottom formwork 46, first adjust the second threaded adjusting seat 32. By adjusting the second threaded adjusting seat 32, adjust the height of the pull rod 44 connected to the first adjusting rod 41. During the position adjustment of the pull rod 44, it drives the connecting ring 43 and the first adjusting rod 41 connected to the connecting ring 43 to be adjusted synchronously. Then adjust the first threaded adjusting seat 25. By adjusting the first threaded adjusting seat 25, adjust the height of the pull rod 44 connected to the second adjusting rod 42.

The inner mold vertical plate 68 is laid on the surface of the inner mold auxiliary bracket 66;

[0078] After the bottom mold and the side mold are set up, the slide block 62 is manually pushed to make the slide block 62 slide along the inner mold slide rail 61. The sliding slide block 62 drives the inner mold main bracket 63, the inner mold horizontal plate 64, the inner mold side plate 65, the inner mold auxiliary bracket 66, the fifth hydraulic push rod 67 and the inner mold vertical plate 68 to move synchronously. When the end of the slide block 62 contacts the end of the bridge and reaches the set position, the slide block 62 is fixed at the set position by bolting. The fifth hydraulic push rod 67 is controlled to extend. During the extension process of the fifth hydraulic push rod 67, the inner mold auxiliary bracket 66 is pushed to make the inner mold auxiliary bracket 66 rotate around the rotating shaft. During the rotation process of the inner mold auxiliary bracket 66, the inner mold vertical plate 68 is driven to turn from the deflected state to the vertical state. At this time, the inner mold horizontal plate 64, the inner mold side plate 65 and the inner mold vertical plate 68 form the inner mold.

[0079] The using method of the self-propelled bridge building machine includes the following steps:

[0080] After the casting of the previous section of the bridge main body is completed, the setting position of the self-propelled main bracket 1 is adjusted;

[0081] Hydraulic pressure is supplied to the hydraulic lifting rod 17 through an external hydraulic device to make the output end of the hydraulic lifting rod 17 extend. The extended output end of the hydraulic lifting rod 17 contacts the bridge surface. During the continuous extension process of the hydraulic lifting rod 17, the hydraulic lifting rod 17 reversely pushes the self-propelled main bracket 1 to lift the self-propelled main bracket 1 relative to the bridge surface;

[0082] After the self-propelled main bracket 1 is lifted, the second hydraulic push rod 18 contracts. The contraction of the second hydraulic push rod 18 drives the main bracket slide rail 19 to make the main bracket slide rail 19 slide along the support frame;

[0083] After the main bracket slide rail 19 slides in place, the hydraulic lifting rod 17 is controlled to retract. As the hydraulic lifting rod 17 retracts, the main bracket slide rail 19 contacts the bridge again, and the main bracket slide rail 19 is fixed to the bridge surface by bolts;

[0084] Control the second hydraulic push rod 18 to extend. The extended second hydraulic push rod 18 pushes the main arm 11 in the reverse direction, causing the main arm 11 to move along the main support slide rail 19. The movement of the main arm 11 synchronously drives the template angle adjustment part 2, the angle adjustment component 3, the bottom template adjustment component 4, the movable side form component 5, and the sliding inner form component 6 to move;

[0085] After the main arm 11 reaches the predetermined position, pass the threaded connecting rod 14 through the through hole preset on the bridge beam segment and thread it with the sliding connecting frame 13, and install the lifting support 15 at the end of the threaded connecting rod 14;

[0086] Control the first hydraulic push rod 16 to extend. The movable end of the first hydraulic push rod 16 pushes the threaded connecting rod 14 upward during the movement process. The upward-moving threaded connecting rod 14 pulls the sliding connecting frame 13 upward, and the template angle adjustment part 2 connected to the sliding connecting frame 13 moves upward under the drive of the sliding connecting frame 13;

[0087] The support roller seat one 22 at the end of the adjusting arm 21 moves upward synchronously with the adjusting arm 21. At the same time, the end of the upward-moving third hydraulic push rod 23 contacts the bridge side wall prior to the adjusting arm 21. When the horizontal height of the adjusting arm 21 reaches the preset height with the sliding connecting frame 13, control the third hydraulic push rod 23 to extend. The extended third hydraulic push rod 23 pushes the adjusting arm 21 in the reverse direction, causing the adjusting arm 21 to rotate relative to the sliding connecting frame 13 around the rotating shaft until the set angle of the rotating adjusting arm 21 meets the usage requirements, and the adjusting arm 21 maintains the set angle;

[0088] Adjust the set angle of the bottom template 46. First, adjust the second threaded adjustment seat 32. By adjusting the second threaded adjustment seat 32, adjust the height of the pull rod 44 connected to the first adjusting rod 41. The pull rod 44 drives the connecting ring 43 and the first adjusting rod 41 connected to the connecting ring 43 to be adjusted synchronously during the position adjustment process. Then, adjust the first threaded adjustment seat 25. By adjusting the first threaded adjustment seat 25, adjust the height of the pull rod 44 connected to the second adjusting rod 42. The pull rod 44 drives the connecting ring 43 and the second adjusting rod 42 connected to the connecting ring 43 to move synchronously during the position adjustment process. Complete the angle setting of the bottom template 46 by adjusting the height difference between the first adjusting rod 41 and the second adjusting rod 42;

[0089] After the set angle of the bottom template 46 is completed, control the second support roller seat 53 to work and extend. During the extension process of the second support roller seat 53, it pushes the side form support 55, causing the side form support 55 to slide along the slideway. The side form support 55 drives the side form 56 during the sliding process, causing the side form 56 to approach the bottom template 46. When the outer wall of the side form 56 contacts the side wall of the bottom template 46, the side form 56 and the bottom template 46 form a complete bottom form and side form;

[0090] After the bottom mold and the side mold are set up, the carriage 62 is manually pushed to slide along the inner mold slide rail 61. The sliding carriage 62 drives the inner mold main support 63, the inner mold transverse plate 64, the inner mold side plate 65, the inner mold auxiliary support 66, the fifth hydraulic push rod 67 and the inner mold vertical plate 68 to move synchronously. When the end of the carriage 62 contacts the end of the bridge and reaches the set position, the carriage 62 is fixed at the set position by bolting. The fifth hydraulic push rod 67 is controlled to extend. During the extension process, the fifth hydraulic push rod 67 pushes the inner mold auxiliary support 66 to make the inner mold auxiliary support 66 rotate around the rotating shaft. During the rotation process, the inner mold auxiliary support 66 drives the inner mold vertical plate 68 to turn from the deflected state to the vertical state. At this time, the inner mold transverse plate 64, the inner mold side plate 65 and the inner mold vertical plate 68 form the inner mold;

[0091] The bottom of the inner mold is closed. After the bottom of the inner mold is closed, the beam end is poured. After the pouring is completed, the pouring of the beam ends of the bridge is repeated one by one.
