Description

Technical Field

[0001] This utility model belongs to the field of railway construction technology, specifically relating to a canopy support system. Background Technology

[0002] In existing technologies, due to the renovation of high-speed rail waiting room lines, culverts 100 are often built under the railway tracks. The existing waiting room canopy columns 10 can affect the construction of the culvert, posing significant safety hazards. For example, vibrations generated during the construction of the culvert 100 or changes in the foundation can cause the canopy columns 10 to become unstable, thus usually requiring their demolition. However, if the solution is to completely demolish the waiting room canopy before constructing the culvert 100, this solution is not only labor-intensive but also prone to creating safety hazards to the high-speed rail line during the demolition process. Utility Model Content

[0003] This utility model provides a canopy support system, which aims to solve the technical problem in the prior art of ensuring normal culvert construction without the need for the overall removal of the canopy.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A canopy support system is provided, including a support truss and a clamping assembly. The support truss is located above the culvert and spans the culvert along its width. Both ends of the support truss are fixedly connected to the foundation. The support truss has through holes for the canopy columns to pass through. The clamping assembly is connected to the support truss and corresponds to the through holes, used to fix and clamp the canopy columns. After the clamping assembly fixes and clamps the canopy columns, the support truss and the foundation together support the canopy frame.

[0005] In one possible implementation, the clamping assembly includes arc-shaped plates and connecting bolts. Two arc-shaped plates are provided. Each arc-shaped plate has a semi-circular groove, and each arc-shaped plate has connecting lugs at both ends. The two arc-shaped plates are used to mate and grip the canopy column. Multiple connecting bolts are provided, each bolt evenly distributed on the two sets of mating connecting lugs, for locking the two mating connecting lugs together.

[0006] In one possible implementation, the arc-shaped plate is integrally welded to the supporting truss.

[0007] In one possible implementation, the canopy support system further includes limiting members. Multiple limiting members are provided. The limiting members are fixedly connected to the canopy columns, located at the top of the arc-shaped plate, and abut against the arc-shaped plate.

[0008] In one possible implementation, the canopy support system further includes a lifting platform, which comprises a platform plate, a top plate, and jacking members. The platform plate is fixedly mounted at the top of the support truss and has through holes for the canopy columns to pass through. The top plate is horizontally positioned above the platform plate and has through holes for the two mating arc-shaped plates to pass through. The top plate is fixedly connected to the two arc-shaped plates. Multiple jacking members are provided, each vertically positioned between the platform plate and the top plate. Each jacking member is used to push the top plate upwards.

[0009] In one possible implementation, each of the pushers is a hydraulic cylinder.

[0010] In one possible implementation, the top plate and the arc-shaped plate are integrally welded.

[0011] In one possible implementation, a settlement monitoring unit is further included, comprising multiple monitoring modules, a processing module, and an early warning module. The multiple monitoring modules are respectively installed on the supporting truss, the canopy columns, and the foundation. The processing module is communicatively connected to the multiple monitoring modules and is used to process the monitoring data from the monitoring modules in real time. The early warning module is communicatively connected to the processing module.

[0012] Specifically, the processing module issues an alarm when it detects that the monitored data exceeds the warning value.

[0013] In one possible implementation, the plurality of monitoring modules include a settlement monitoring module, a tilt monitoring module, and a stress monitoring module.

[0014] This embodiment provides a canopy support system. Compared with the prior art, the canopy support system includes a support truss, a clamping assembly, and a limiting member. First, the support truss spans across the culvert, with both ends fixedly connected to the foundation. The canopy column is vertically inserted within the support truss. Second, one end of the clamping assembly is fixedly connected to the support truss, and the other end is clamped and fixedly connected to the canopy column. After the support truss clamps the canopy column, it replaces the pile foundation of the canopy column. This solves the technical problem in the prior art where the entire canopy needs to be removed to ensure normal culvert construction. Simultaneously, to prevent the canopy column from slipping during clamping, a limiting member is also provided. The limiting member is fixedly installed on the canopy column and positioned above the clamping assembly. When the canopy column slips, the limiting member, being above the clamping assembly, effectively restricts the sliding of the canopy column, improving the safety and applicability of this application.

[0027] Please refer to the following: Figure 1 and Figure 2 The present invention will now describe a canopy support system.

[0028] A canopy support system includes a support truss 1 and a clamping assembly 2. The support truss 1 is located above a culvert 100 and spans across the culvert 100 along its width. Both ends of the support truss 1 are fixedly connected to a foundation 200. The support truss 1 has through holes for canopy columns 10 to pass through. The clamping assembly 2 is connected to the support truss 1 and corresponds to the through holes, used to fix and clamp the canopy columns 10. After the clamping assembly 2 fixes and clamps the canopy columns 10, the support truss 1 and the foundation 200 together support the canopy frame.

[0029] This embodiment provides a canopy support system. Compared with the prior art, the canopy support system includes a support truss 1, a clamping component 2, and a limiting component 3. First, the support truss 1 is laid horizontally across the culvert 100, with both ends of the support truss 1 fixedly connected to the foundation 200. The canopy column 10 is vertically inserted into the support truss 1. Second, one end of the clamping component 2 is fixedly connected to the support truss 1, and the other end of the clamping component 2 is clamped and fixedly connected to the canopy column 10. This allows the support truss 1 to replace the pile foundation of the canopy column 10 after being fixedly clamped by the clamping component 2. This solves the technical problem in the prior art where the entire canopy needs to be removed to ensure normal construction of the culvert 100.

[0030] Specifically, there can be multiple clamping components 2. The canopy column 10 is clamped by multiple clamping components 2, which is safer and more stable than a single clamping component 2.

[0031] In some embodiments, the clamping component 2 described above may employ, for example... Figure 2 The structure shown. See also Figure 2 The clamping assembly 2 includes an arc-shaped plate 21 and connecting bolts 23. Two arc-shaped plates 21 are provided. Each arc-shaped plate 21 has a semi-circular groove, and each arc-shaped plate 21 has connecting lugs 22 at both ends. The two arc-shaped plates 21 are used to fit together and grip the canopy column 10. Multiple connecting bolts 23 are provided, each connecting bolt 23 being evenly distributed on the two sets of mating connecting lugs 22, used to lock the two mating connecting lugs 22 in each mating assembly.

[0032] Two connecting lugs 22 are respectively set on different arc-shaped plates 21 and together form a set of mating connecting lugs 22. That is, the connecting bolts 23 pass through the connecting lugs 22 on the two arc-shaped plates 21 respectively.

[0033] After the two curved plates 21 are joined together, they clamp the canopy column 10, and simultaneously, the curved plates 21 are locked into a whole by connecting bolts 23. This solution, by clamping the canopy column 10 instead of using traditional welding, facilitates assembly and disassembly while avoiding the impact of welding and cutting on the material of the canopy column 10 and the overall stability of the waiting canopy. This application not only avoids affecting the service life of the canopy column 10 but also prevents instability of the waiting canopy during later construction, thus ensuring the safe operation of the high-speed rail line.

[0034] In some embodiments, the arc plate 21 is integrally welded to the supporting truss 1.

[0035] Based on the above embodiments, in order to avoid axial displacement of the canopy column 10 during the lifting process, the canopy support system also includes a limiting member 3. Multiple limiting members 3 are provided. The limiting member 3 is fixedly connected to the canopy column 10, and is located at the top of the arc-shaped plate 21, abutting against the arc-shaped plate 21.

[0036] Since the limiting member 3 is fixedly installed on the canopy column 10 (i.e., welded to the canopy column 10) and is located on the top plate 42 of the arc-shaped plate 21, the lower part of the limiting member 3 abuts against the top plate 42 of the arc-shaped plate 21. When the canopy column 10 settles, the limiting member 3 abuts against the top plate 42 of the arc-shaped plate 21, thus preventing the canopy column 10 from settling, further improving the safety and applicability of this system.

[0037] Specifically, multiple limiting components 3 are welded at intervals around the central axis of the canopy column 10 on the outer periphery of the canopy column 10.

[0038] Please see Figure 3In other embodiments, the canopy support system further includes a lifting platform 4, which comprises a platform plate 41, a top plate 42, and jacking members. The platform plate 41 is fixedly mounted on the top of the support truss 1, and has through holes for the canopy columns 10 to pass through. The top plate 42 is horizontally positioned above the platform plate 41 and has through holes for two mating arc-shaped plates 21 to pass through. The top plate 42 is fixedly connected to the two arc-shaped plates 21. Multiple jacking members are provided, each vertically positioned between the platform plate 41 and the top plate 42. Each jacking member is used to push the top plate 42 upwards.

[0039] Specifically, the top plate 42 and the arc plate 21 are welded together as a single unit.

[0040] The top plate 42 is welded to the arc plate 21 as a whole. The jacking component is vertically set between the platform plate 41 and the top plate 42. The power output end of the jacking component is connected to the top plate 42, and the jacking component applies an upward jacking force to the top plate 42. Since the top plate 42 and the arc plate 21 are welded together, the jacking component ultimately applies an upward force to the arc plate 21. In addition, after the two arc plates 21 hug the canopy column 10, the load-bearing capacity of the canopy column 10 is offset by the jacking component, so that the pile foundation of the canopy column 10 is not stressed, thus avoiding the instability of the canopy column 10 during the subsequent construction of the culvert 100.

[0041] Specifically, each jacking component is a hydraulic cylinder.

[0042] In other embodiments, the jacking component may also be an electric push rod, a jack, or a hydraulic cylinder.

[0043] Hydraulic cylinders are hydraulic actuators that effectively convert hydraulic energy into mechanical energy. They are used to perform linear reciprocating motion. The entire device has a simple structure and reliable operation. When used to achieve reciprocating motion, it eliminates the need for a speed reduction device and has no transmission backlash. It runs very smoothly and is therefore widely used in the hydraulic systems of various machines.

[0044] The output force of a hydraulic cylinder is directly proportional to the effective area of ​​the piston and the pressure difference between the two sides. A hydraulic cylinder is basically composed of a cylinder barrel and cylinder head, a piston and piston rod, a sealing device, a buffer device, and an exhaust device.

[0045] Hydraulic cylinders come in various structural forms. Based on their motion, they can be effectively classified into linear reciprocating motion and rotary oscillating motion. According to the hydraulic pressure applied, they can be classified into single-acting and double-acting types. Based on their structural form, they can be classified into piston type, plunger type, and oscillating type.

[0046] In a single-acting hydraulic cylinder, pressurized oil is supplied to only one chamber, and the cylinder moves in one direction by hydraulic pressure. Reverse movement is achieved by external forces such as spring force, gravity, or external loads. In contrast, the piston in a double-acting hydraulic cylinder moves in both directions by alternating oil supply to both chambers, relying on hydraulic pressure.

[0047] Piston hydraulic cylinders can be divided into two types: single-rod and double-rod. They are fixed in two ways: by the cylinder body or by the piston rod. Based on the application of hydraulic pressure, they are classified as single-acting or double-acting. In a single-acting hydraulic cylinder, pressurized oil is supplied to only one chamber, and the cylinder moves in one direction due to hydraulic pressure. Reverse movement is achieved by external forces such as spring force, gravity, or external loads. In a double-acting hydraulic cylinder, the piston moves in both directions by alternating oil supply to both chambers, relying on hydraulic pressure.

[0048] An electric linear actuator, also known as a linear drive, is a new type of linear actuator mainly composed of a motor, a linear actuator, and a control device. It can be considered an extension of the structure of a rotary motor.

[0049] An electric linear actuator is an electrically driven device that converts the rotary motion of an electric motor into the linear reciprocating motion of a linear actuator. It can be used as an actuator in various simple or complex processes to achieve remote control, centralized control, or automatic control.

[0050] Electric linear actuators are characterized by their novel and exquisite design, small size, high precision, perfect synchronization, good self-locking performance, hygiene, and direct motor drive, eliminating the need for air or oil pipelines. They are now widely used in equipment across various industries, including production lines, automobiles, ventilation window opening systems, military applications, stage equipment, textiles, and wastewater treatment.

[0051] In other embodiments, a plurality of support columns 43 are provided between the top plate 42 and the platform plate 41, with both ends of the support columns 43 abutting against the top plate 42 and the platform plate 41 respectively. When the jacking component fails, the support columns 43 can provide support and prevent the overall jacking system from becoming unstable.

[0052] Based on the above embodiments, this application further includes a settlement monitoring unit, which comprises multiple monitoring modules, a processing module, and an early warning module. The multiple monitoring modules are respectively installed on the supporting truss 1, the canopy column 10, and the foundation 200. The processing module is communicatively connected to the multiple monitoring modules and is used to process the monitoring data from the monitoring modules in real time. The early warning module is communicatively connected to the processing module.

[0053] Specifically, the processing module issues an alarm when it detects that the monitored data exceeds the warning value.

[0054] The settlement monitoring unit can effectively monitor the underpinning truss 1, canopy column 10, and foundation 200 in real time. The processing module processes the monitoring data in real time. When abnormal data is detected, the early warning module responds and promptly reminds the project construction personnel. At the same time, corresponding solutions are adopted based on the monitoring data to ensure the safe and stable operation of the project construction.

[0055] Specifically, the multiple monitoring modules include a settlement monitoring module, a tilt monitoring module, and a stress monitoring module.

[0056] Settlement monitoring module, tilt monitoring module and stress monitoring module are provided on the supporting truss 1, canopy column 10 and foundation 200 according to actual needs, or one or more, so as to better monitor the supporting truss 1, canopy column 10 and foundation 200 and improve the safety of the overall system.

[0057] Settlement monitoring modules are used to monitor the vertical displacement (settlement or uplift) of the ground surface, buildings, foundations, etc., and to detect potential uneven settlement hazards in a timely manner. They are commonly used in scenarios such as geological disaster early warning, building construction monitoring, and subway tunnel operation and maintenance.

[0058] Tilt monitoring modules are used to monitor changes in the tilt angle or posture of structures (such as buildings, bridges, and chimneys) to prevent the risk of collapse due to excessive tilt. They are commonly used in the protection of ancient buildings, construction of super high-rise buildings, and slope stability analysis.

[0059] Stress monitoring modules are used to monitor stress or strain changes inside structures (such as concrete beams, steel structures, and soil and rock masses) to assess structural load-bearing capacity and safety. They are commonly used in bridge health monitoring, tunnel support, and mine pressure analysis.

[0060] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
