Description

Technical Field

[0001] This utility model relates to the field of mechanical engineering technology, and in particular to a bridge quick replacement device. Background Technology

[0002] Existing technologies mainly include blasting, chiseling, cutting, rotation, and jacking. Blasting generates significant noise and air pollution, limiting its application and impacting traffic and society. Chiseling is noisy, has a significant environmental impact, and a long construction period. Cutting has limitations on lifting weight, high safety risks, and low efficiency. Rotation is generally used for special bridge structures, requiring large sites and significant investment in rotation equipment. Jacking is mainly for steel bridges and requires a large amount of temporary construction equipment and materials.

[0003] Generally, self-propelled hydraulic modular vehicles use fixed-height steel pipe supports and padding steel plates to form a carrying support structure, which is insufficient in terms of scenario adaptability. In traditional bridge rapid replacement methods, the height of the carrying beam support is fixed and cannot be adjusted. The relocation of bridges with large clearances is risky. During the relocation process, some support points may become detached, resulting in uneven stress and the need for manual filling of support points with steel plates. These methods suffer from problems such as low overall flexibility and poor adaptability. Summary of the Invention

[0004] In view of the shortcomings of the prior art, the technical problem to be solved by this patent application is how to provide a bridge rapid replacement equipment to realize the rapid dismantling of existing bridges and the rapid installation of new bridges, so as to minimize the impact on existing traffic.

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

[0006] A bridge quick replacement device includes two modular vehicles arranged opposite each other. The upper end of each modular vehicle has a support platform, and both ends of the support platform are fixedly installed with lifting bracket modules.

[0007] The lifting support module includes four column structures fixedly installed on a support platform. Each column structure includes a guide sleeve, a column, a lifting cylinder, a conversion sleeve, an upper pin, and a lower pin. The guide sleeve is fixedly installed on the support platform, and the column slides with the guide sleeve. The two sides of the guide sleeve extend outward to form cylinder seats. The conversion sleeve has sliding holes that slide with the column. The two ends of the lifting cylinder are hinged to the cylinder seat and the conversion sleeve, respectively. The column has several locking holes along the vertical direction. The conversion seat has a through hole, and the guide sleeve has several through holes along the vertical direction. An upper seat and a lower seat are fixedly installed on the conversion sleeve and the guide sleeve, respectively. An upper cylinder and a lower cylinder are fixedly installed on the upper seat and the lower seat, respectively. The upper cylinder is fixedly connected to the upper pin, and the lower cylinder is fixedly connected to the lower pin. The upper pin is positioned opposite the through hole, and the lower pin is positioned opposite one of the through holes.

[0008] The four pillars are arranged in a rectangular shape.

[0009] The lower ends of adjacent guide sleeves are fixedly connected by reinforcing rods.

[0010] The adjacent cylinder seats are fixedly connected by the first connecting rod, and the side of the adjacent guide sleeve without a cylinder seat is fixedly connected by the second connecting rod.

[0011] A stiffening plate is fixed between the cylinder seat and the guide sleeve.

[0012] The lifting cylinder is connected to a pressure sensor and a pressure gauge.

[0013] The upper end of the lifting bracket module is fixed with a rectangular support frame.

[0014] In summary, this bridge rapid replacement equipment has the following beneficial effects:

[0015] 1. Achieve rapid demolition of existing bridges and rapid installation of new bridges, minimizing the impact on existing traffic (traffic closure time controlled within hours).

[0016] 2. By utilizing the coordinated movements of the guide sleeve, column, conversion sleeve, lifting cylinder, and pin, a larger column lifting stroke can be achieved with a smaller cylinder stroke.

[0017] 3. The modular vehicle can be equipped with one or two layers of lifting support modules to adapt to different bridge height conditions.

[0018] 4. A pressure sensor was added to monitor the pressure at each support point in real time, and to adjust the action of the evacuation cylinder with less force, thereby improving the uneven force distribution.

[0019] 5. Features automatic beam segment attitude detection and adjustment. After supporting the beam segment onto the lifting support module, the tilt sensor is installed on the beam segment's reference surface and connected to the tilt sensor socket. The tilt data is uploaded, detecting the beam segment's lateral and longitudinal tilt angles. The data is then calculated into displacement information for each individual lifting cylinder and sent to that cylinder. The beam segment's attitude is adjusted by regulating the height of the lifting cylinder. Attached Figure Description

[0030] like Figure 1-5 As shown, a bridge 100 quick replacement equipment includes two modular vehicles 1 arranged opposite each other. The upper end of each modular vehicle has a support platform, and both ends of the support platform are fixedly installed with lifting bracket modules 2.

[0031] The lifting support module includes four column structures 3 fixedly installed on a support platform. Each column structure includes a guide sleeve 4, a column 5, a lifting cylinder 6, a conversion sleeve 7, an upper pin 8, and a lower pin 9. The guide sleeve is fixedly installed on the support platform. The column slides with the guide sleeve. The two sides of the guide sleeve extend outward to form a cylinder seat 10. The conversion sleeve has a sliding hole that slides with the column. The two ends of the lifting cylinder are hinged to the cylinder seat and the conversion sleeve, respectively. The column has several locking holes 11 in the vertical direction. The conversion seat has a through hole. The guide sleeve has several through holes 12 in the vertical direction. An upper seat and a lower seat are fixedly installed on the conversion sleeve and the guide sleeve, respectively. An upper cylinder 13 and a lower cylinder 14 are fixedly installed on the upper seat and the lower seat, respectively. The upper cylinder is fixedly connected to the upper pin, and the lower cylinder is fixedly connected to the lower pin. The upper pin is positioned opposite the through hole, and the lower pin is positioned opposite one of the through holes.

[0032] During implementation, the four pillar structures are arranged in a rectangular pattern.

[0033] During implementation, the lower ends of adjacent guide sleeves are fixedly connected by reinforcing rods 15.

[0034] In practice, adjacent cylinder seats are fixedly connected by the first connecting rod 16, and the side of the adjacent guide sleeve without a cylinder seat is fixedly connected by the second connecting rod 17.

[0035] During implementation, a stiffening plate 18 is fixed between the cylinder seat and the guide sleeve.

[0036] During implementation, the lifting cylinder is connected to a pressure sensor and a pressure gauge.

[0037] During implementation, a rectangular support frame 19 is fixed to the upper end of the lifting bracket module.

[0038] Specifically, the modular vehicle is a self-propelled modular vehicle.

[0039] By utilizing a column, conversion sleeve, lifting cylinder, upper pin, and lower pin, a large lifting stroke of the column can be achieved with a short cylinder stroke. The upper and lower pins are operated by hydraulic cylinders, i.e., upper and lower cylinders, avoiding the need for inserting and removing the pins at heights and improving equipment safety.

[0040] The column raising process is as follows: 1. The upper hydraulic cylinder drives the upper pin to insert into the through hole and locking hole, while the lower hydraulic cylinder drives the lower pin to pull out of the through hole and locking hole. Simultaneously, the lifting hydraulic cylinder extends, raising the column. 2. When the lifting hydraulic cylinder extends to its end stroke, it aligns the holes of the column and guide sleeve. After alignment, the lower hydraulic cylinder drives the lower pin to insert, while the upper hydraulic cylinder drives the upper pin to pull out. The lifting hydraulic cylinder retracts, and the conversion sleeve retracts as well. After the lifting hydraulic cylinder is fully retracted, it aligns the holes of the conversion sleeve and the column. The upper hydraulic cylinder drives the upper pin to insert, while the lower hydraulic cylinder drives the lower pin to pull out. Repeating steps 1 and 2 allows the column to be continuously raised to the bottom of the bridge.

[0041] The hydraulic cylinders can operate synchronously during the column lifting process. Four columns form a lifting support module, and two lifting support modules are mounted on a modular vehicle. The two modular vehicles and their corresponding lifting support modules can work together to complete the bridge demolition operation.

[0042] The hydraulic system is equipped with pressure sensors and pressure gauges at the outlets of the vertical cylinders and pump stations. The pressure sensors collect data through the electrical system, monitor the pressure value of the vertical cylinders in real time, and adjust the action of the detached cylinders with less force to improve the uneven force distribution.

[0043] The autonomous lifting support has the function of automatic attitude detection and adjustment of beam segments.

[0044] Synchronization of the lifting cylinder's movements, such as Figure 6 The system employs an electronic scale to monitor the cylinder stroke in real time and uses closed-loop control to achieve synchronous movement of the lifting cylinders. Specifically, when the stroke difference between the two lifting cylinders exceeds 2cm, the faster lifting cylinder stops moving, while the slower cylinder continues. When the difference is less than 2cm, both lifting cylinders continue to extend synchronously.

[0045] The fulcrum is subjected to uniform force, such as Figure 7 :

[0046] Each support point of the autonomous lifting support module has a force detection and adjustment function. After the beam segment is supported on the lifting support module, the pressure sensor is built into the cylinder to upload the pressure data, detect the pressure value of each support point of the beam, calculate the pressure information of each lifting cylinder, calculate the average pressure of the lifting cylinder, identify the lifting cylinder with the least force, determine the lifting cylinder that is partially detached, and make corresponding adjustments. The movement of the other lifting cylinders stops, and the detached lifting cylinder continues to extend until the force on the support point is uniform.

[0047] Attitude detection and adjustment, such as Figure 8 and Figure 9 :

[0048] The autonomous lifting support module features automatic beam segment attitude detection and adjustment. After the beam segment is supported on the lifting support module, an inclination sensor is installed on the beam segment's reference surface and connected to the inclination sensor socket. The inclination data is uploaded, detecting the beam segment's lateral and longitudinal tilt angles. The data is then calculated into displacement information for individual lifting cylinders and sent to them. By adjusting the height of the lifting cylinders, the beam segment's attitude is adjusted.

[0049] Taking into account the actual dimensions of the beam segments and facilitating calculations, the upper plane of the beam is used as the segmented description model. A three-dimensional coordinate system is constructed with the center point of the beam segment plane as the origin.

[0050] Step 1: Align the reference segment using an inclination sensor placed on the reference plane of the beam segment.

[0051] Step 2: Connect the tilt sensor data to the control system.

[0052] Step 3: The system adjusts the beam segment by adjusting the lifting cylinder.

[0053] Step 4: Make line AB parallel to the Y-axis.

[0054] Step 5: Adjust the line AD to be parallel to the X-axis.

[0055] Finally, it should be noted that those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims and their equivalents, this utility model also intends to include these modifications and variations.
