Description

Technical Field

[0001] The invention belongs to the technical field of track plate clamping devices, and in particular relates to a multifunctional pressure bar for a track plate. Background Art

[0002] As an important structural component of the CRTSⅢ slab track structure, the self-compacting concrete layer plays a key role in connecting the upper and lower parts and transmitting the longitudinal, transverse and vertical loads from the upper track structure. Its construction quality determines the success or failure of the CRTSⅢ slab track structure. In the existing self-compacting concrete construction process, the self-compacting concrete layer is set between the track plate and the base. During the pouring and molding process, it is necessary to limit the edge sealing around the self-compacting concrete filling layer, and to ensure the discharge of air in the self-compacting concrete. At the same time, it is necessary to apply downward pressure to the self-compacting concrete filling layer above the track plate to prevent the track plate from floating and shifting when pouring the self-compacting concrete, or the track plate position changes due to human trampling after fine adjustment. In the existing construction process, if no measures are taken, the track plate will float and the track plate and the self-compacting concrete layer will be separated, which will bring great harm to the construction.

[0003] Existing track plate clamping bars include steel clamping devices, aluminum alloy track plate clamping devices, detachable track plate clamping devices, etc. However, none of them can intuitively display whether the clamping device has clamped the track plate. The clamping force can only be adjusted according to the work experience of the construction personnel, and some track plates often float and deflect. Summary of the invention

Detailed implementation manners

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0019] As Figure 1-6 shown, the present invention provides a technical solution: a multi-functional pressing bar for a track slab, including a pressing rod 1, the pressing rod 1 is horizontally placed on the top surface of the track slab, and a set of pressing components and a set of pressing force feedback devices are arranged at both ends of the pressing rod 1; the pressing components include a sliding column 2, a fixed column 3, a lead screw 4 and a locking nut 5, the lower end of the fixed column 3 is fixedly connected to the side wall of the base plate, the upper end of the sliding column 2 is connected to the end of the pressing rod 1, the fixed column 3 is inserted into the bottom of the sliding column 2 so as to be movable up and down relative to the sliding column 2, the lead screw 4 is connected to the top of the fixed column 3 and the upper end of the lead screw 4 extends upward through the top of the sliding column 2, the locking nut 5 is threadedly connected to the upper end of the lead screw 4, and the bottom of the locking nut 5 abuts against the top surface of the sliding column 2; the pressing force feedback device includes a hydraulic cylinder, an oil delivery pipe 7 and a liquid pressure display device for measuring and displaying the liquid pressure, the hydraulic cylinder is connected between the lead screw 4 and the fixed column 3, and the oil delivery pipe 7 is connected between the oil outlet of the hydraulic cylinder and the liquid pressure display device for delivering the hydraulic oil in the hydraulic cylinder to the liquid pressure display device.

[0020] By setting the pressing components and the pressing force feedback device, when in use, the locking nut 5 is rotated, the lead screw 4 drives the hydraulic cylinder to rise, the lower end of the fixed column 3 is fixedly connected to the side wall of the base plate, the sliding column 2 moves downward under the action of the pressing force, drives the pressing rod 1 to press the track slab, and at the same time the pressure in the hydraulic cylinder increases accordingly, the oil delivery pipe 7 delivers the hydraulic oil to the liquid pressure display device to display the magnitude of the pressing force in real time, so that the staff can intuitively monitor the change of the pressing force in real time, improve the construction efficiency, and ensure that the pressing force of each track slab reaches the design requirements, avoiding the floating and deviation of the track slab caused by insufficient pressing force.

[0021] Further, the liquid pressure display device is a hydraulic pressure gauge 8, which is connected to the oil delivery pipe 7 to measure and display the pressure value of the hydraulic oil conveyed by the oil delivery pipe 7. When the pressing lever is used for the first time, the staff can use a torque wrench to screw the locking nut 5 until the locking nut 5 reaches the designed torque value, and record the value displayed by the hydraulic pressure gauge 8 at this position. After that, an ordinary wrench can be used to screw the locking nut 5, and only need to observe whether the hydraulic pressure gauge 8 reaches the specified value, which improves the construction efficiency of the staff and can ensure that the pressing force of each track slab meets the design requirements. Specifically, the hydraulic pressure gauge 8 is arranged on the surface of the pressing rod 1, which is convenient for the staff to check in real time.

[0022] Further, the liquid pressure display device includes a hydraulic pressure sensor 91, a PLC controller 92, a communication module 93 and a power supply 94. The power supply 94 is electrically connected to the hydraulic pressure sensor 91, the PLC controller 92 and the communication module 93 to provide power. The hydraulic pressure sensor 91 is connected to the oil delivery pipe 7 to measure the pressure value of the hydraulic oil conveyed by the oil delivery pipe 7 and convert it into an electrical signal for sending. The PLC controller 92 is electrically connected to the hydraulic pressure sensor 91 and the communication module 93 to receive the electrical signal sent by the hydraulic pressure sensor 91 and control the communication module 93 to send it to an external computer or a mobile terminal for display or storage. Therefore, it is possible to check whether the pressing forces of all pressing levers meet the requirements through an external computer or a mobile terminal without being on the construction site, or store the pressing force values in an external computer or a mobile terminal for record filing.

[0023] Further, in the ultra-high section, the base plate and the track slab are inclined, with one side of the base plate higher than the other side. Correspondingly, the pressure bar 1 also needs to be inclined and attached to the surface of the track slab. In the present invention, the upper end of the sliding column 2 is hinged to the end of the pressure bar 1. There is a fixing plate 11 below the end of the pressure bar 1. There are ear plates 21 on both sides of the sliding column 2. There are vertical strip holes 211 on the ear plates 21. A tension bolt 111 is connected to the ear plate 21. The bolt head of the tension bolt 111 abuts against the surface of the ear plate 21, and its screw rod passes through the strip hole 211 and is threadedly connected to the fixing plate 11. There is an extension rod 63 at the top of the fixed column 3. The extension rod 63 is slidably inserted into the top of the fixed column 3. A number of first pin holes 631 horizontally penetrating the extension rod 63 are arranged at equal intervals along the axial direction of the extension rod 63. There is a second pin hole 31 horizontally penetrating the fixed column 3 at the top of the fixed column 3. The second pin hole 31 is aligned with one of the first pin holes 631 and a pin 32 is connected in the hole. A vertical groove 22 for the pin 32 to slide up and down is formed on the surface of the sliding column 2. The upper end of the extension rod 63 is connected to the hydraulic cylinder. During use, first place the pressure bar 1 on the surface of the track slab, then turn the sliding column 2 downward from the hinge to make it vertically connected to both sides of the base plate, then fixedly connect the fixed column 3 to the base plate, adjust the extension rod 63 inserted into the top of the fixed column 3 to an appropriate height, fix it with the pin 32, and then thread the tension bolt 111 through the strip hole 211 of the ear plate 21 and threadedly connect it to the fixing plate 11. Tighten the screw rod to make the sliding column 2 drive the fixed column 3 to closely adhere to both sides of the base plate, so as to ensure that the whole structure can also be used during the construction of the ultra-high section.

[0024] Specifically, the hydraulic cylinder includes a cylinder block 61 and a piston rod 62. The cylinder block 61 is connected to the bottom of the screw rod 4, and the piston rod 62 is connected to the top of the extension rod 63. The oil outlet at the lower part of the cylinder block 61 is connected to the oil delivery pipe 7. During use, rotate the locking nut 5, the screw rod 4 drives the cylinder block 61 to rise, the fixed column 3 restricts the piston rod 62 from rising, and the pressure at the lower part of the cylinder block 61 increases accordingly. The hydraulic oil at the lower part of the cylinder block 61 is transported from the oil outlet to the liquid pressure display device through the oil delivery pipe 7.

[0025] Further, there is a fixing hole 33 horizontally penetrating the fixed column 3 at the bottom of the fixed column 3, so that the fixed column 3 can be fixed to both sides of the base plate by using a pin to pass through the fixing hole 33.

[0026] Further, a tightening bolt 112 is threadedly connected to the fixing plate 11. The end of the tightening bolt 112 abuts against the side formwork surface of the track slab. During work, the tightening bolt 112 abuts against both sides of the side formwork of the track slab, so as to prevent the pressure bar from tilting.

[0027] Furthermore, the PLC controller 92, communication module 93 and power supply 94 are arranged inside the control box. The control box is detachably connected to the surface of the pressure bar 1. The hydraulic pressure sensor 91 is arranged inside the pressure bar 1. Opposite wire outlets 97 are provided on the control box and the pressure bar 1. During use, the communication power supply wires of the PLC controller 92, communication module 93 and power supply 94 are connected to the communication power supply wires of the hydraulic pressure sensor 91 through plugs at the wire outlet 97, and then the control box is installed on the surface of the pressure bar 1. Or the communication power supply wires are disconnected from each other, and then the control box is disassembled, which is convenient to take away the electric control module after disassembly, for charging and to avoid damage caused by being exposed to wind, rain and other elements at the construction site for a long time.

[0028] Furthermore, the control box includes a box body 95 and a box cover 96. One side of the box body 95 facing the pressure bar 1 is open. The box cover 96 covers the opening of the box body 95. Connecting plates 951 are arranged on both sides of the opening of the box body 95. Calabash holes 952 are arranged on the connecting plates 951. Screws are connected to the surface of the pressure bar 1. The box body 95 is hung on the screws on the surface of the pressure bar 1 through the calabash holes 952 on the connecting plates 951, so as to realize the detachable connection of the control box to the surface of the pressure bar 1.

[0029] Furthermore, a spring 41 is sleeved on the lead screw 4. The upper end of the spring 41 abuts against the lower part of the top of the sliding column 2, and the lower end of the spring 41 abuts against the top of the hydraulic cylinder, so as to provide a pre-tightening force for the hydraulic cylinder.
