Description
Technical Field
[0001] The utility model relates to the technical field of rail transportation, in particular to a floating roadbed jacking device. Background Art
[0002] With the development of society and the progress of science and technology, the importance of rail transit is increasingly prominent. In the construction of rail transit, the vibration and noise problems generated by vehicle operation must be solved, otherwise it will seriously affect the quality of life of surrounding residents and endanger the safety of surrounding buildings. At the same time, the stability, safety and service life of rail transit itself will also be affected. In order to control the vibration and noise generated in rail transit operation, researchers have developed many vibration reduction and noise reduction products, among which the steel spring floating ballast bed technology is recognized by the industry as one of the technologies with the best vibration reduction effect. Among the various steel spring floating ballast bed structures, the built-in steel spring floating ballast bed is the most widely used. In this type of structure, the floating plate of the floating ballast bed has a built-in connecting sleeve, and an elastic vibration isolator is installed in the connecting sleeve. However, it is found in practice that since the elastic vibration isolator in this floating ballast bed structure is built into the floating plate, it cannot be directly observed from the outside. During the installation and leveling stage of the floating ballast bed, only the position of the floating ballast bed is controlled, and the actual working state of the elastic vibration isolator cannot be measured and determined. During the operation stage of the floating ballast, the actual stress conditions of the elastic isolators are not easy to measure and monitor. When unexpected situations occur, such as local settlement or spring breakage of a single elastic isolator, they are often not discovered in time. Daily inspection and maintenance are difficult and can easily cause certain safety hazards.
[0003] In view of this, the market urgently needs a device and tool that can easily and quickly check and measure the actual stress conditions of elastic vibration isolators. Utility Model Content
[0004] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a floating roadbed lifting device.
[0005] The technical solution adopted by the utility model is as follows:
[0006] A floating track bed lifting device comprises a sleeve, a clamping claw, a jack, a load sensor, a displacement sensor and a data processing module. The sleeve is provided with a cavity and can accommodate and install the jack. Three clamping claws are evenly distributed along the circumference of the outer surface of the sleeve. The data processing module is electrically connected to the load sensor and the displacement sensor respectively.
[0007] The load sensor is a force sensor installed on the top of the sleeve cavity. The top of the jack contacts the load sensor. The bottom of the sleeve is provided with an end cover, and the end cover is provided with a piston clearance hole of the jack. The end cover and the sleeve are connected by threads. Under this structure, the reaction force of the jack when loading is transmitted to the sleeve through the force sensor at the top, and finally transmitted to the built-in structure of the floating ballast bed through three claws, so as to realize the compression of the elastic isolator and the lifting of the floating plate.
[0008] Furthermore, the device also includes a protective shell for installing a load sensor, and the protective shell is provided with a threaded interface adapted to the piston rod of the jack. The corresponding load sensor is a force sensor, which is installed in the protective shell and connected to the piston of the jack. In addition, the load sensor is a pressure sensor arranged on the hydraulic pipeline of the jack. At this time, the load value loaded by the jack can be calculated through the pressure value of the hydraulic pipeline, and the lifting load on the floating ballast bed can also be accurately measured.
[0009] The displacement sensor is built into the jack, or mounted on the sleeve through a bracket, and is used to measure the displacement of the jack piston rod. The displacement sensor can be a contact displacement sensor such as a pull rope displacement sensor, a pull rod displacement sensor, or a non-contact displacement sensor such as an infrared ranging sensor or an ultrasonic ranging sensor. As long as the range and measurement accuracy requirements are met, they can be used and belong to the protection scope of the displacement sensor described in the utility model.
[0010] Furthermore, a handle is provided above the sleeve, and the data processing module is installed on the handle. The handle is a U-shaped structure, and the two vertical sides of the U-shaped structure are connected to the sleeve, and the data processing module is installed between the two vertical sides of the U-shaped structure by bolts. By providing a handle, the lifting device can be easily carried and the convenience of application is improved. By installing the data processing module on the handle, the integrity and integration of the entire device are improved, and it is more suitable for the work site.
[0011] The data processing module is a closed shell, with operation buttons, a display screen and a transmission interface arranged on the shell surface, and a built-in power supply, a data display module, a data acquisition module, an alarm module, a data storage module and a transmission interface arranged inside the shell.
[0012] The data processing module also includes a wireless data transmission module. At this time, the utility model also includes a portable data acquisition device, which includes a tablet computer, a laptop computer, and a smart phone, and can be connected to the wireless data transmission module of the data processing module. In specific applications, a portable data acquisition device can be connected to one or more data processing modules, which is conducive to forming a measurement effect of centralized collection and comprehensive comparison.
[0013] When in use, the jacking device is set between the connecting sleeve of the floating ballast and the elastic isolator, which can measure the jacking force of the jack and the telescopic displacement of the piston rod. Then, the data processing module in the jacking device is used to calculate and display the force value of the elastic isolator. The static load of the elastic isolator can be detected at any time, so as to grasp the actual load-bearing condition of the elastic isolator. In addition, during use, the built-in parameters can be set by operating the buttons, and the measurement results can be alarmed by sound and light through the alarm module. By using the jacking device, the force data of the elastic isolator can be mastered during the jacking installation stage of the floating ballast, which is conducive to improving the construction and installation quality, giving full play to the performance of the floating ballast, and ensuring the safety and comfort of the subway line operation.
[0014] When used on existing lines, the actual load-bearing state of the elastic vibration isolator can be measured according to the above application method, and the load-bearing state of the elastic vibration isolator can be tracked and monitored. Specifically, the static load borne by each elastic vibration isolator in the floating ballast structure can be measured and recorded in advance, and the measurement data can be exported through the data transmission interface or wireless transmission module and a record file can be established; after working for a period of time, the static load borne by the elastic vibration isolator can be re-checked, and the static load value obtained by the spot check and re-test can be compared with the static load value measured previously. If the change is within the allowable range, the elastic vibration isolator is assumed to be in a normal state; if the change exceeds the allowable value, the elastic vibration isolator needs to be removed for confirmation, and the elastic vibration isolator can be repaired or replaced according to the actual situation, which is very accurate and convenient.
[0015] Compared with the prior art, the utility model has the following beneficial effects:
[0016] (1) The device can measure the static load actually borne by the elastic isolator in the built-in floating slab track structure at any time without removing the elastic isolator on site, so as to accurately determine the actual working state of the elastic isolator, effectively improving the problem of the working state of the elastic isolator in the prior art that it is difficult to identify, inspect and maintain, and easily cause safety hazards; at the same time, it has the characteristics of simple structure, high integration, high accuracy, and easy operation.

The outer shell surface of the data processing module 6 is provided with a display module 61 and a button 62.
[0023] The load sensor is a force sensor installed at the top of the sleeve cavity, and the top of the jack contacts the load sensor.

The specific internal structure is not shown here.
[0024] When used, the jacking device in this embodiment is arranged between the connecting sleeve and the elastic vibration isolator of the floating ballast. The reaction force of the jack 2 during loading is transmitted to the sleeve 1 through the force sensor at the top, and finally transmitted to the built-in structure of the floating ballast through three claws, so as to realize the compression of the elastic vibration isolator and the jacking of the floating plate.

[0025] When used on existing lines, the actual load-bearing state of the elastic vibration isolator can be measured according to the above application method, and the load-bearing state of the elastic vibration isolator can be tracked and monitored. Specifically, the static load borne by each elastic vibration isolator in the floating ballast structure can be measured and recorded in advance, and the measurement data can be exported through the data transmission interface or wireless transmission module and a record file can be established; after working for a period of time, the static load borne by the elastic vibration isolator can be re-checked, and the static load value obtained by the spot check and re-test can be compared with the static load value measured previously. If the change is within the allowable range, the elastic vibration isolator is assumed to be in a normal state; if the change exceeds the allowable value, the elastic vibration isolator needs to be removed for confirmation, and the elastic vibration isolator can be repaired or replaced according to the actual situation, which is very accurate and convenient.
[0026] The floating ballast bed lifting device in this embodiment can measure the static load actually borne by the elastic isolator in the built-in floating plate ballast bed structure at any time without removing the elastic isolator on site, so as to accurately determine the actual working state of the elastic isolator, and effectively improve the problems in the prior art that the working state of the elastic isolator is difficult to identify, difficult to inspect and maintain, and easy to cause safety hazards. At the same time, it has the characteristics of simple structure, high integration, high accuracy, and easy operation. This device can be widely used in rail transit lines such as subways, ground light rails, and elevated tracks that use built-in floating plate ballast bed structures. It is suitable for daily inspections of rail lines during skylight time, and can also be used for preparations for raising and leveling the floating plate ballast bed before the formal operation of new rail transit lines. In addition, the floating ballast bed lifting device in this embodiment can also be used for the installation, detection and measurement of built-in elastic isolators of floating floors in building structures.
[0027] Based on the technical principle of the jacking device of the utility model recorded in this example, the loading device can also use other forms of loading elements such as electric screws or ball screw structures; the displacement sensor can also be a pull-rope displacement sensor, or other types of non-contact displacement sensors; the load sensor and the displacement sensor can be connected to the data processing module by wireless means in addition to being connected by wired cables. The above contents are all simple changes based on the technical principle of the utility model, and can achieve good technical effects. They are only explained in text here, and no more drawings are provided one by one. They are all within the protection scope required by the utility model.
[0028] Embodiment 2
[0029] like Figure 2 The utility model floating track bed lifting device is shown in FIG. Figure 1The difference of the illustrated embodiment 1 is that a protective shell 41 for installing a load sensor is provided, and a threaded interface adapted to the piston rod of the jack 2 is provided on the protective shell 41 and connected to the piston of the jack. The load sensor 4 is installed in the protective shell 41. The displacement sensor 3 is installed on the sleeve 1 through the bracket 31. The data processing module 6 is a closed shell structure, and is separated from the sleeve 1. A data display module 61, a button 62 and a data transmission interface 63 are provided on the surface of the data processing module, and a built-in power supply, a data display module, a data acquisition module, an alarm module, and a data storage module are provided inside. The data processing module 6 is connected to the load sensor 4 and the displacement sensor 3 using a wired cable 64. The sleeve 1 accommodates the jack 2, and the two are connected by threads.
[0030] The displacement sensor is a pull-rope type displacement sensor. In order to measure the displacement of the jack piston rod, a structure connected to the end of the pull rope is provided on the protective shell of the load sensor. The specific structure will not be described in detail here.
[0031] When in use, the jacking device is placed in the connecting sleeve of the floating track bed. The claw 8 is in contact with the connecting sleeve. The bottom end of the load sensor protective shell 41 is directly pressed against the upper surface of the elastic vibration isolator. At this time, the jacking force of the jack piston rod is directly transmitted to the elastic vibration isolator through the load sensor housing and the load sensor. The load sensor can measure the load applied to the elastic vibration isolator. The extension of the piston rod can directly pull the measuring head of the displacement sensor to move, thereby measuring the telescopic distance of the piston rod. The data processing module 6 collects load and displacement data through the wired cable 64, calculates and displays relevant results. In addition, during use, the built-in parameters can be set by operating the buttons, and the measurement results can be alarmed with sound and light through the alarm module.
[0032] Of course, based on the technical principles of this example, the displacement sensor can also be other forms of contact displacement sensors and non-contact displacement sensors. As long as they can measure the extension and contraction of the jack piston rod, they can be used in the floating track bed jacking device of the utility model and are within the protection scope required by the utility model.
[0033] Embodiment 3
[0034] like Figure 3 The utility model floating track bed lifting device is shown in FIG. Figure 2 The difference of the technical solution shown is that the load sensor 4 is a pressure sensor arranged on the hydraulic pipeline 12. The hydraulic pipeline 12 is connected to the hydraulic pump 10 and the jack 2. The data processing module 6 is connected to the displacement sensor 3 by wireless. The data processing module 6 also includes a wireless data transmission module. The jacking device in this embodiment also includes a portable data acquisition device 9, which is connected to the wireless data transmission module of the data processing module 6.
[0035] Portable data acquisition devices include tablet computers, laptop computers, and smart phones. In this embodiment, it is a tablet computer. In specific applications, a portable data acquisition device can be connected to one or more data processing modules. In this embodiment, a solution that can connect four data processing modules at the same time is adopted.
[0036] When the jacking device of the utility model is applied, the data processing module 6 can calculate the load value of the jack 2 according to the data of the load sensor 4 and the structural parameters of the jack 2. In specific applications, a portable data acquisition device can be connected to one or more data processing modules, which is conducive to forming a measurement effect of centralized collection and comprehensive comparison.
[0037] Compared with the second embodiment, in the technical solution described in this example, since the data processing module and the displacement measuring device are connected wirelessly, the data processing module and the hydraulic pump can be set on other vehicles, such as a rail car. This is conducive to reducing the weight of the part of the jacking device that needs to be manually carried, and is more conducive to reducing the size and weight requirements of the data processing module, and realizing more functions. The data processing module is also connected to the portable data acquisition device wirelessly, so fewer components are involved, and it is more convenient to use on site. It is more conducive to improving the data processing capability and intelligence of the jacking device through the powerful data processing function of the portable data acquisition device.
[0038] In addition, based on the principles of this embodiment and the second embodiment, the load sensor can be a pressure sensor installed on the hydraulic pipeline of the jack and a force sensor installed on the jack. In this way, the data of the two sensors can be mutually verified, which can better provide the reliability of the entire system. The detailed structure of this solution will not be described in detail here.
[0039] The embodiments in the present invention are only for better illustrating the technical solutions of the present invention and should not be regarded as limiting the present invention. The technical features in many embodiments may also be used interchangeably. Based on the technical principles of the present invention, those skilled in the art may re-combine the technical solutions described in the above embodiments or simply replace some of the components therein with similar technologies. As long as they are based on the technical principles of the present invention, they are within the protection scope required by the present invention.
