Description

Technical Field

[0001] The utility model relates to the technical field of engineering construction auxiliary tools, in particular to an anchor modification concentric circle positioning anchoring device. Background Art

[0002] High-speed railways are mainly laid with ballastless tracks, where the tracks are anchored in the ballast plate (track plate), and the track plate (track plate) is fixed by threaded connections between the anchor bolts (spikes) and the embedded parts. If the anchor bolts (spikes) are broken and / or the threads in the embedded parts are stripped, a bench-top water drill is needed to perform anchor drilling operations to replace new anchor bolts (spikes).

[0003] Since the anchor bolt (spike) position requires high precision, the corresponding desktop water drill positioning accuracy must also be high. Therefore, it is necessary to mark and locate before drilling to determine the drilling position, and mark and locate again after drilling the hole to mark the implantation position of the anchor bolt so that the replacement anchor bolt is basically in the same position as the previous anchor bolt. In this process, on the one hand, it is necessary to mark and locate multiple times, which is quite troublesome. On the other hand, it is also difficult to determine the center position of the drilled hole and implant the anchor bolt with high requirements, which is also quite time-consuming.

[0028] The following will be combined with the drawings in the utility model to clearly and completely describe the technical solution of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments.

In addition, the terms "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0030] Embodiment 1:

[0031] like Figure 1 and Figure 2 As shown, a concentric circle positioning anchoring device comprises a horizontal base plate 1, a positioning circular hole 2 is provided in the middle of the horizontal base plate 1, a circular ring 3 is provided in the positioning circular hole 2, the circular ring 3 is connected to the positioning circular hole 2 by a plurality of radial spokes 4, and a height positioning cylinder 5 is also provided on the circular ring 3; the positioning circular hole 2, the circular ring 3 and the height positioning cylinder 5 are arranged on a common central axis, and the central axis passes through the center point of the horizontal base plate 1.

[0032] The modified anchor concentric circle positioning anchoring device has a simple structure, is easy to use, has a good concentric positioning function, has high consistency in multiple positioning at the same position, is conducive to improving the high-precision concentricity requirements of drilling holes and anchor bolts (spikes), and improves construction efficiency.

[0033] The horizontal base plate 1 can be placed directly on the plane to be positioned, and the circle that needs to be drilled can be determined first using the positioning hole 2. The ring 3 is set to form a concentric circle in the positioning hole, and the height positioning cylinder 5 is installed using the ring 3, so that the height positioning cylinder 5 can also be set concentrically.

[0034] The height positioning cylinder 5 can be used to position the anchor bolts or spikes. The anchor bolts and spikes need to be higher than the track bed by a certain height. For the same line, this height is usually a fixed value. Therefore, the height positioning cylinder can be designed with this fixed value. In this way, when the anchor bolts or spikes are arranged, it can be ensured that their exposed heights are the same, and the distances from the bottom of the anchoring holes in the lower ends of the anchor bolts or spikes are also consistent.

[0035] This modified anchor concentric circle positioning anchor device can be well used for replacing anchor bolts used to fix fasteners on railway track plates, greatly improving the efficiency and accuracy of its replacement. The specific operation is as follows:

[0036] Remove the fasteners, take out the height adjustment washers of the fasteners at the defective part from both sides, and raise the base plate to expose the gap, take out the anchor bolts, remove the fastener system, and put them in order;

[0037] Drilling, place the horizontal bottom plate at the position where the fasteners are removed, one side of the horizontal bottom plate 1 abuts against the lower wing edge of the rail, horizontally adjust the position of the horizontal bottom plate 1 so that the center of the horizontal bottom plate 1 coincides with the center position of the original anchor bolt, draw a line along the inner circumference of the positioning circular hole, remove the horizontal bottom plate after drawing the line, use a drilling rig to drill, align the drill sleeve of the drilling rig with the drawn position to drill a cylindrical hole, i.e., the anchor hole 8, on the track plate; use the circumference of the bottom end of the drill bit to correspond to the pre-drawn positioning circle to determine the plane position of the drill bit;

[0038] Roughen and clean the hole wall, clean the dust and debris on the edge of the hole, and prepare for the anchoring of the planting tube (rebar or anchor bolt). Since the hole wall drilled by the water drill is relatively smooth, the hole wall must be roughened when using grouting material for anchoring to ensure the anchoring force;

[0039] Plant the cylinder (rib or anchor bolt), set the horizontal base plate 1 on the track plate again, let the positioning circular hole 2 coincide with the drilled anchor hole 8, and insert the anchor bolt 9 into the height positioning cylinder 5 (such as Figure 3 As shown), grouting is injected into the anchor hole, and after the anchor material is initially set, the device can be removed; then the surface is processed as required, and the removed fastener system is installed.

[0040] In this process, since the positioning circular hole 2, the circular ring 3 and the height positioning cylinder 5 are arranged on the same central axis, there is no need for secondary marking and secondary positioning, and there is no need to find the center position of the anchor bolt again. The anchor bolt can be directly set to ensure that the anchor bolt and the original anchor bolt are in the same position, so that the fastener system can continue to be installed at the original position and the rail can continue to be fixed at the same position.

[0041] Furthermore, a plurality of reflective identification stickers 6 are provided on the horizontal bottom plate 1 and on the outer periphery of the height positioning tube 5. The reflective identification stickers 6 are provided so that they are easy to identify and convenient to determine the position under the effect of light; this is because the maintenance window time of most railway lines is at night, so the reflective identification stickers are provided, which is not only a requirement for nighttime construction, but also a way for parts to be identified.

[0042] Preferably, the horizontal bottom plate 1 is a square plate with four rounded corners, and an indicator mark 10 is provided at the center point of each side to facilitate initial positioning.

[0043] Furthermore, the horizontal bottom plate 1 is a metal plate, the circular ring 3 is a metal ring, the radial spokes 4 are metal strips, and the height positioning tube 5 is a metal tube; the horizontal bottom plate 1, the circular ring 3 and the radial spokes 4 are connected as a whole by welding, and the circular ring 3 and the height positioning tube 5 are also welded. The device made by this connection method is durable, not easy to deform, and the size and shape are well maintained.

[0044] Embodiment 2:

[0045] The difference between this embodiment and the first embodiment is that the height positioning tube is arranged differently.

[0046] like Figure 4 and Figure 5 As shown, the height positioning cylinder 5 is an adjustable telescopic cylinder, and a scale mark 12 in the height direction is provided on the outer circumference of the telescopic cylinder.

[0047] The height positioning tube 5 is set to be telescopic to facilitate height adjustment, because the height of the anchor bolt exposed will be slightly different for different lines, so the positioning height can be appropriately adjusted according to different project requirements. The setting of the scale mark 12 can obtain the height value in real time, avoiding the need to measure the height value with a ruler every time, which is more convenient during the adjustment process.

[0048] Furthermore, the bottom and side of the horizontal bottom plate 1 are provided with anti-skid pads 11. The provision of the anti-skid pads 11 can increase friction, prevent the horizontal bottom plate 1 from sliding randomly during use, and can also protect the device, the track plate and the rails, with less wear.

[0049] Embodiment three:

[0050] The difference between this embodiment and the first embodiment is that a detachably connected height positioning cylinder is provided.

[0051] like Figure 6 and Figure 7 As shown, the inner circumference of the circular ring 3 is provided with a circle of first clamping grooves 13, the first clamping grooves 13 are provided with a plurality of magnetic positioning protrusions 14, the bottom of the height positioning cylinder 5 is provided with a plurality of positioning holes, the height positioning cylinder 5 is installed on the first clamping grooves 13, and the magnetic positioning protrusions 14 are inserted into the positioning holes. In this case, the horizontal bottom plate, the circular ring and the radial spokes are still connected by welding.

[0052] The height positioning sleeve can be easily installed or disassembled through the above connection method, and different height positioning sleeves can be replaced according to needs, and the height positioning sleeve can be omitted during the marking process.

[0053] Embodiment 4:

[0054] The difference between this embodiment and the first embodiment is that a detachably connected ring is provided.

[0055] like Figure 8 and 9 As shown, the circular ring 3 and the radial spoke 4 are connected as a whole, a plurality of second snap-fit ​​grooves 15 are provided on the edge of the positioning circular hole 2, and plug-in protrusions 16 are respectively provided on the second snap-fit ​​grooves 15, and a snap-fit ​​portion 18 cooperating with the second snap-fit ​​groove 15 is provided on the end of the radial spoke 4, and a plug-in hole 17 cooperating with the plug-in protrusion 16 is provided on the snap-fit ​​portion 18.

[0056] With such an arrangement, the radial spokes 4 can be connected to the plug-in protrusions 16 through the plug-in holes 17, and the entire ring can be separated from the horizontal bottom plate and can be used in a split form; when marking for the first time, a full circle can also be drawn.

[0057] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
