Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of bridge building machines, more particularly, the present application relates to a bridge building machine walking mechanism and walking method based on a smart bridge building machine. BACKGROUND

[0002] A smart bridge building machine is a new type of bridge building equipment that integrates modern information technology, automation control technology and intelligent monitoring technology. Compared with traditional bridge building machines, a smart bridge building machine has higher intelligence and automation levels, as well as stronger real-time monitoring and decision-making capabilities.

[0003] In the construction process of continuous bridges, the bridge building machine uses a segmental pushing method, that is, after completing a segment of the girder (such as one span or a part of the bridge), the bridge building machine needs to move forward to the next segment for new girder pouring or hoisting operations.

[0004] And in order to improve construction efficiency and enhance safety, after the main girder segment is constructed, a precast girder segment can be hoisted and fast connection technology can be used (which can be used to fix the main girder segment and the precast girder segment by pouring concrete after the precast girder segment is hoisted), which can shorten the on-site construction time and improve the construction efficiency. This method is usually faster than traditional on-site pouring, reduces dependence on weather conditions, and reduces the complexity of high-altitude operations with ground precast girder segments and standardized connection methods, thereby improving the safety of the overall construction process and reducing the risk of accidents.

[0005] However, when building a bridge by hoisting a precast girder segment and using fast connection technology, the precast girder end needs to be positioned by hoisting. During the hoisting process, since the hoisting is a high-altitude operation, it is difficult to accurately align when the external environment is unstable, such as strong winds, causing the main girder segment and the precast girder segment to deviate, which affects the construction precision.

Those skilled in the art can make some non-essential improvements and adjustments to the present application according to the above application content.

[0037] The accompanying drawings are referred to in the description of the present application. Figures 1 to 3The application discloses a bridge building machine walking mechanism based on a smart bridge building machine, which comprises a main beam section 1 and a new beam section 2, the main beam section 1 is provided with a guide rail 3, the guide rail 3 is provided with a main truss 4 capable of walking along the path of the guide rail 3, the bottom of the main beam section 1 is provided with a bottom basket 5, the new beam section 2 is hoisted and arranged on the bottom basket 5, and the new beam section 2 is provided with a connecting mechanism 6, which is used for positioning and connecting the main beam section 1 and the new beam section 2.

[0038] The connecting mechanism 6 comprises a plurality of positioning columns 61, the guide rail 3 is provided with a plurality of positioning holes 631 matched with the positioning columns 61, and the connecting mechanism 6 is positioned by matching the positioning columns 61 with the corresponding positioning holes 631, so as to position the main beam section 1 and the new beam section 2.

[0040] It should be noted that the number of the positioning columns 61 and the positioning holes 631 can be four, the positioning columns 61 can be arranged on the new beam section 2 in a pre-buried manner in the pouring process of the new beam section 2, and the positioning holes 631 can be formed in a fixed seat, and the fixed seat can be fixed on the guide rail 3 through bolts.

[0041] It should be further noted that the adjusting mechanism 7 can be a multi-degree-of-freedom hydraulic jack matched with a hydraulic cylinder, the new beam section 2 is supported by the multi-degree-of-freedom hydraulic jack, and the new beam section 2 is adjusted to be horizontally aligned with the main beam section 1, then the hydraulic cylinder drives the new beam section 2 to move towards the main beam section 1, the positioning columns 61 are inserted into the positioning holes 631, and the new beam section 2 and the main beam section 1 are accurately positioned.

[0042] The implementation scene is specifically: first, a hoisting mechanism (the hoisting mechanism can be a common hoisting device such as a crane) can be used to hoist the new beam section 2 by the crane, and hoist the new beam section 2 to the multi-degree-of-freedom hydraulic jack on the bottom basket 5, support the new beam section 2 by the multi-degree-of-freedom hydraulic jack, and adjust the new beam section 2 to be horizontally aligned with the main beam section 1, and then drive the new beam section 2 to move towards the main beam section 1 by the hydraulic cylinder, insert the positioning column 61 into the positioning hole 631, and realize accurate positioning of the new beam section 2 and the main beam section 1, solve the problem that the new beam section 2 and the main beam section 1 are easily offset during hoisting, and affect the accuracy, and then pour concrete between the new beam section 2 and the main beam section 1, fix the new beam section 2 and the main beam section 1, and after the concrete is set, all locking mechanisms (including some mechanical locking mechanisms or hydraulic locking mechanisms used for locking, the mechanical locking mechanism can use high-strength bolts to connect and fix the bridge builder with the support structure, and the bolts must be loosened before moving, the hydraulic locking mechanism can be used to fix the equipment at a certain height or position by using the resident pressure of the hydraulic cylinder, and the hydraulic pressure needs to be removed when the locking mechanism is released) at the current position of the bridge builder are released, and a traction mechanism (the traction mechanism can be a common traction device such as a winch) is used to pull the main truss 4 and the bottom basket 5 to the preset position, so as to accurately hoist the other new beam section 2.

[0043] Further, referring to the drawings attached to the specification Figure 2 and Figure 3 The connecting mechanism 6 further comprises a positioning seat 63 installed at the end of the guide rail 3, and the positioning hole 631 is formed in the positioning seat 63, and the positioning column 61 is arranged on the new beam section 2, the end of the positioning column 61 is provided with a threaded shaft 611, the positioning column 61 is fixedly provided with a stop plate 62, and the threaded shaft 611 is threadedly connected with a nut 64, and the nut 64 abuts against the positioning seat 63.

[0044] It should be noted that the threaded shaft 611 arranged at the end of the positioning column 61 can make the stop plate 62 contact the positioning seat 63 after the positioning column 61 is inserted into the positioning hole 631, and the nut 64 is screwed on the threaded shaft 611 by manual operation, so that the nut 64 is tightly attached to the positioning seat 63, and the fastening and fixing between the new beam section 2 and the main beam section 1 are completed.

[0045] In the above technical scheme, in the hoisting process, the new beam section 2 is supported by the multi-degree-of-freedom hydraulic jack, and is adjusted to be in horizontal alignment with the main beam section 1, and then the hydraulic cylinder drives the new beam section 2 to move towards the main beam section 1, the positioning column 61 is inserted into the positioning hole 631, and the precise positioning of the new beam section 2 and the main beam section 1 is realized, but in this process, if the new beam section 2 deviates a lot during hoisting, the angle and position of the new beam section 2 need to be adjusted for many times, so that the precise positioning is realized, but at this time, the angle adjustment and position adjustment of the new beam section 2 for many times will delay the construction time, therefore, the specific structure of the adjusting mechanism 7 is provided, which can precisely position the new beam section 2 during hoisting when the wind is large, and can also quickly realize the precise positioning of the new beam section 2 and the main beam section 1.

[0046] Specifically, referring to the description attached Figure 4 and Figure 5 , the adjusting mechanism 7 is arranged on the bottom basket 5, the adjusting mechanism 7 is used for adjusting the position of the new beam section 2 and positioning and connecting the new beam section 2 and the main beam section 1, the adjusting mechanism 7 includes two groups, and the two groups of adjusting mechanisms 7 are symmetrically arranged on the bottom basket 5, the adjusting mechanism 7 includes a linear drive assembly one 71, a linear drive assembly two 72, a linear drive assembly three 73 and a support seat 74, the linear drive assembly two 72 is installed on the output end of the linear drive assembly one 71, the linear drive assembly three 73 is installed on the output end of the linear drive assembly two 72, and the support seat 74 is installed on the output end of the linear drive assembly three 73, the linear drive assembly one 71 includes a power component one 711, the output end of the power component one 711 is provided with a moving seat 712, the linear drive assembly two 72 includes a base 721, the base 721 is installed on the moving seat 712, the base 721 is provided with a power component two 722, the output end of the power component two 722 is provided with a lead screw 723, the moving seat 712 is slidably provided with a sliding seat 724, the sliding seat 724 is threadedly connected with the lead screw 723, and the linear drive assembly three 73 is installed on the sliding seat 724.

[0047] It should be noted that by setting the adjusting mechanism 7 as two groups, and the two groups of adjusting mechanism 7 are symmetrically arranged on the bottom basket 5, the power component one 711 and the linear drive assembly three 73 can be hydraulic cylinders, and the power component two 722 can be a motor. When hoisting, the new beam section 2 is hoisted in the air, and the new beam section 2 is located on the bottom basket 5, first, two power component ones 711 can be driven at the same time, so that the two power component ones 711 can drive the support seats 74 on both sides to move close to each other, and the sides of the support seats 74 are in contact with the two sides of the new beam section 2, so that the support seats 74 on both sides can clamp the new beam section 2, then the corresponding support seats 74 are driven by the linear drive assembly three 73 to move vertically upward, so that the top of the support seats 74 on both sides can be in contact with the bottom of the new beam section 2, and then the new beam section 2 can be fixed on the two groups of adjusting mechanism 7, and then the hoisting mechanism releases the new beam section 2, and then the corresponding support seats 74 are driven by the linear drive assembly three 73 to reset the movement, so as to adjust the new beam section 2 to the position aligned with the main beam section 1 in the horizontal direction, finally, the support seats 74 drive the new beam section 2 to move towards the main beam section 1 by the linear drive assembly two 72, and the positioning column 61 is inserted into the corresponding positioning hole 631, so as to realize the precise positioning of the new beam section 2 and the main beam section 1.

[0048] It should be further noted that one group of adjusting mechanism 7 can include two support seats 74, and the two support seats 74 can be arranged far apart, so that four support seats 74 can be used to support the new beam section 2, and the support seats 74 on the same side can be used to ensure stable support of the new beam section 2.

[0049] Further, referring to the drawings Figure 6 and Figure 7 The end of the main truss 4 is provided with a walking assembly 41, and the walking assembly 41 includes a walking seat 411 mounted on the end of the main truss 4, and the walking seat 411 is provided with walking wheels 4111 in rolling contact with the guide rail 3.

[0050] It should be noted that the bottom of the main beam section 1 is also provided with a walking assembly 41 for the bottom basket 5 to walk.

[0051] In the above technical solution, the main truss 4 is pulled to walk by the traction mechanism, and the walking wheels 4111 roll on the guide rail 3 to control the walking of the main truss 4, but during the walking process, due to the traction walking, when the traction is stopped, the main truss 4 will walk a distance under the action of inertia, thereby causing the main truss 4 to deviate from the preset position, thereby affecting the construction precision. To solve this problem, the application provides a speed reduction mechanism 8 for reducing the speed of the main truss 4 before stopping traction, so as to solve the problem that the main truss 4 will walk a distance under the action of inertia.

[0052] Specifically, referring to the description attached Figure 7 And Figure 8 The walking seat 411 is provided with a deceleration mechanism 8, the deceleration mechanism 8 comprises a power component three 81, the power component three 81 is installed on the walking seat 411, the output end of the power component three 81 is provided with a moving plate 82, two circular shafts 821 are fixedly arranged in the moving plate 82, two friction increasing seats 83 are slidably arranged in the walking seat 411, and the two friction increasing seats 83 are both provided with inclined guide openings 831, and the two circular shafts 821 are movably arranged in the corresponding guide openings 831.

[0053] It should be noted that the power component three 81 is a hydraulic cylinder, when the traction mechanism is about to stop traction, the moving plate 82 is driven to move by the hydraulic cylinder, so that the moving plate 82 drives the two circular shafts 821 to move synchronously in the moving process, so that the two circular shafts 821 can move in the corresponding guide openings 831, and as Figure 7 As shown in the figure, the two guide openings 831 are both inclined, that is, when the two circular shafts 821 move in the corresponding guide openings 831, they drive the two friction increasing seats 83 to move away from each other, and make the two friction increasing seats 83 contact with the corresponding walking wheels 4111, so that when the two friction increasing seats 83 contact with the walking wheels 4111, the rolling of the walking wheels 4111 can be limited by increasing friction through contact, thereby reducing the rolling of the walking wheels 4111, so that the walking of the main truss 4 can be slowed down, and the main truss 4 can stop in time when reaching the preset position.

[0054] In addition, in the above technical solution, when the traction mechanism is about to stop traction, the walking of the main truss 4 is slowed down, so that the main truss 4 can stop in time when reaching the preset position, but although the walking distance under inertia is reduced by slowing down, the walking distance of the main truss 4 under inertia is still difficult to accurately control, and problems such as not reaching the preset position or exceeding the preset position are prone to occur, therefore, the present application sets a stop seat 92 on the guide rail 3, and sets a resisting seat 91 on one side of the walking seat 411, so that when the resisting seat 91 contacts with the stop seat 92, the position of the main truss 4 is the preset position, at this time, the driving of the deceleration mechanism 8 needs to be controlled to be slightly late, so as to avoid that the deceleration is too early, causing the walking distance of the main truss 4 to be too short and not reaching the position where the resisting seat 91 contacts with the stop seat 92, but when the resisting seat 91 contacts with the stop seat 92, the resisting seat 91 will collide with the stop seat 92, causing impact force and mechanical vibration when the resisting seat 91 collides with the stop seat 92, at this time, the main truss 4 is prone to rebound and reset walking due to the collision, so at this time, the problem of not reaching the preset distance still exists, therefore, the present application further provides a clamping mechanism 9 for clamping and fixing the resisting seat 91 when the resisting seat 91 contacts with the stop seat 92, so as to ensure that the main truss 4 can directly stop moving when reaching the preset position.

[0055] Specifically, referring to the drawings Figure 9 The main beam section 1 is further provided with a blocking seat 92, the blocking seat 92 is provided with a clamping mechanism 9, the clamping mechanism 9 comprises a resisting seat 91, the clamping mechanism 9 is used for fixing between the resisting seat 91 and the blocking seat 92 when the resisting seat 91 is in contact with the blocking seat 92, the clamping mechanism 9 further comprises two power components four 93, the two power components four 93 are respectively arranged on the two sides of the resisting seat 91, and the output ends of the two power components four 93 are all provided with clamping plates 94.

[0056] It should be noted that the power component four 93 is a hydraulic cylinder, a pressure sensor can be arranged on one side of the blocking seat 92, and a PLC is arranged, when the pressure sensor detects that the resisting seat 91 is in contact with the blocking seat 92, a signal is transmitted to the PLC, the hydraulic cylinders on the two sides are controlled by the PLC to drive the two clamping plates 94 to move close to each other and clamp the resisting seat 91, so that the main truss 4 can be directly stopped when reaching the preset position.

[0057] Referring to the drawings Figure 10 A walking method of a bridge building machine walking mechanism based on a smart bridge building machine, comprising the following steps:

[0058] Step one, before hoisting the new beam section 2, ensure that the pre-set connecting mechanism 6 has been accurately installed on the main beam section 1 and the new beam section 2 according to the design requirements;

[0059] Step two, hoist the new beam section 2 through the hoisting mechanism, and under the action of the connecting mechanism 6 and the adjusting mechanism 7, quickly physically connect and fix the new beam section 2 and the main beam section 1 by using the pre-set connecting mechanism 6;

[0060] Step three, pour concrete between the new beam section 2 and the main beam section 1 to fix the new beam section 2 and the main beam section 1, and after confirming that the new beam section 2 has been firmly connected to the main beam section 1, release all the locking mechanisms;

[0061] Step four, walk the main truss 4 and the bottom basket 5 in sequence through the traction mechanism, and under the action of the speed reduction mechanism 8 and the clamping mechanism 9, stop the movement of the main truss 4 and the bottom basket 5 immediately after reaching the preset position, and then lock and fix each component through the locking mechanism.

[0062] The above-described embodiments only express several embodiments of the present application, and the description is more specific and detailed, but it cannot be understood as limiting the scope of the patent of the present application. It should be noted that for ordinary skilled persons in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which all belong to the protection scope of the present application.
