Description

Technical Field

[0001] This utility model relates to the technical field of railway sleeper spike construction, and specifically to a fixing device for anchoring railway sleeper spikes. Background Technology

[0002] Train operation is guided and the load is transferred from the rails to the concrete sleepers, and then distributed to the track bed by the concrete sleepers. The concrete sleepers and rails are connected by fasteners. As an important component of the fasteners, the concrete sleeper bolts are susceptible to defects such as bolt breakage, corrosion, and exceeding the geometric limits of the concrete sleeper bolts under the load and impact of train operation and the influence of the natural environment, which seriously affect the stability of the equipment.

[0003] In particular, the temperature stress of seamless rails is currently high. If many bolts fail and the clamping pressure is not up to standard, it is very easy to cause rail expansion or rail breakage, which can lead to traffic accidents. The existing bolt anchoring operation method has a qualified bolt rate of only 70%. The main problem is that the geometric dimensions of the anchoring operation are not easy to control. Summary of the Invention

[0004] The purpose of this invention is to provide a fixing device for anchoring sleeper spikes, so as to solve the above-mentioned defects caused by the prior art.

[0005] The fixing device for anchoring sleeper spikes includes a handle symmetrically arranged on one side of a base. A limiting mechanism is provided on the outer side of the base. The limiting mechanism adjusts the distance between the two symmetrically arranged bases according to the width of the track, thereby aligning the anchoring parts of the two sets of spikes. A positioning mechanism is provided directly below the base. The positioning mechanism clamps both sides of the track, thereby positioning the bottom end of the base and preventing the spikes from shaking during the curing process.

[0006] Preferably, the limiting mechanism includes a base, a rail spike bracket, a transverse connecting rod, fastening holes, an inner sleeve rod, and a guide cavity. The rail spike bracket is symmetrically arranged on the outer side of the base. A guide cavity is opened on one side of the base. An inner sleeve rod is arranged inside the guide cavity. A transverse connecting rod is connected through one side of the inner sleeve rod. Fastening holes are opened at equal intervals on the outer side of the transverse connecting rod.

[0007] Preferably, the base is connected to one side of the transverse connecting rod via a guide cavity provided on one side.

[0008] Preferably, the positioning mechanism includes a first clamping piece, a second clamping piece, a rubber pad, and a fastener. The first clamping piece is symmetrically arranged at the bottom end of the base. The second clamping piece is provided on one side of the first clamping piece. The fastener is connected through the outer side of the second clamping piece. The rubber pad is bonded to both sides of the second clamping piece.

[0009] Preferably, the clamping piece is connected to both sides of the base via fasteners connected to the outer side.

[0010] Preferably, the spike bracket is provided with a strong magnet inside.

[0011] Preferably, the base is connected to the outside of the transverse connecting rod through fastening holes that are equally spaced through.

[0012] Compared with the prior art, the present invention has the following advantages:

[0013] 1. Adjust the spacing between the two sets of bases, then insert the bolts into the fastening holes to lock the transverse connecting rod to the base. This facilitates the transverse unfolding and storage of the base, saving space required during use. After the anchoring is completed and the strength is achieved, use a pull-out tester to test the pull-out force. The pull-out force must not be less than 60KN. After on-site testing, the concrete sleeper was tested for the relevant pull-out force. The test results meet the relevant technical requirements for concrete sleepers specified in railway standards.

[0014] 2. This utility model patent features a simple structure, convenient operation, and easy removal, reducing the workload of anchoring workers, saving operation time, and improving the anchoring quality of railway sleeper spikes. The magnet in the spike bracket of the anchoring frame automatically controls the spiral spike to deviate from the center of the pre-drilled hole by no more than 2mm, ensuring the spiral spike is perpendicular to the rail support platform with a deviation of no more than 2 degrees, meeting the specifications. It solves the problems of spike misalignment and non-standard anchoring height caused by traditional manual screw-in anchoring, guaranteeing anchoring quality with a near 100% pass rate.

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] like Figures 1 to 4 As shown, the fixing device for anchoring sleeper spikes includes a handle 1, which is symmetrically arranged on one side of a base 2. A limiting mechanism 7 is provided on the outer side of the base 2. The limiting mechanism 7 adjusts the distance between the two symmetrically arranged bases 2 according to the width of the track, thereby aligning the anchoring parts of the two sets of spikes. A positioning mechanism 8 is provided directly below the base 2. The positioning mechanism 8 clamps the two sides of the track, thereby positioning the bottom end of the base 2 and preventing the spikes from shaking during the curing process.

[0023] In this embodiment, the limiting mechanism 7 includes a base 2, a rail spike bracket 3, a transverse connecting rod 4, fastening holes 5, an inner sleeve rod 12, and a guide cavity 13. The rail spike bracket 3 is symmetrically arranged on the outer side of the base 2. The guide cavity 13 is opened on one side of the base 2. The inner sleeve rod 12 is arranged inside the guide cavity 13. The transverse connecting rod 4 is connected through one side of the inner sleeve rod 12. Fastening holes 5 are opened at equal intervals on the outer side of the transverse connecting rod 4. The rail spike is wrapped by the rail spike bracket 3 to facilitate the limiting of the rail spike.

[0024] In this embodiment, the base 2 is connected to one side of the transverse connecting rod 4 through a guide cavity 13 provided on one side. The guide cavity 13 positions both sides of the transverse connecting rod 4 to prevent the base 2 from becoming loose.

[0025] In this embodiment, the positioning mechanism 8 includes a clamping piece 6, a clamping piece 9, a rubber pad 10, and a fastener 11. The clamping piece 6 is symmetrically arranged at the bottom end of the base 2. The clamping piece 9 is provided on one side of the clamping piece 6. The fastener 11 is connected through the outer side of the clamping piece 9. The rubber pad 10 is bonded to both sides of the clamping piece 9. The rubber pad 10 increases the clamping friction of the clamping piece 6 and the clamping piece 9.

[0026] In this embodiment, the clamping piece 16 is connected to both sides of the base 2 via the fastener 11 connected to the outside, and the two sets of clamping pieces 16 and clamping pieces 29 clamp the two sides of the track.

[0027] In this embodiment, a strong magnet 14 is provided inside the rail spike bracket 3. The strong magnet 14 attracts the top of the rail spike to prevent the rail spike from becoming loose.

[0028] In this embodiment, the base 2 is connected to the outside of the transverse connecting rod 4 through fastening holes 5 that are equally spaced through. The transverse connecting rod 4 connects the two sides of the base 2 through, which facilitates the device to unfold and store the base 2.

[0029] In practical applications, this type of sleeper spike anchoring device includes the following tasks:

[0030] Step 1: During use, the base 2 is placed on the track, and the rail spike is directly inserted into the rail spike bracket 3. The rail spike bracket 3 connects with the rail spike through the strong magnet 14 at the top, and the rail spike is attracted by the strong magnet 14. The top of the rail spike is held by the magnet, and the spiral rail spike is fixed on the rail spike bracket 3. This ensures that the length of the lower thread of the spiral rail spike matches the reserved hole in the concrete. The two rail spike brackets 3 are respectively set to correspond to the anchor holes of the sleepers.

[0031] Step 2: Simultaneously, the operator can pull the spike bracket 3 according to the width of the track, so that the spike bracket 3 slides on the outside of the transverse connecting rod 4, and the transverse connecting rod 4 slides laterally in the inner sleeve rod 12 to adjust the distance between the two sets of bases 2. Then, the bolts are inserted into the fastening holes 5 to lock the transverse connecting rod 4 and the base 2, which facilitates the lateral unfolding and storage of the base 2, saving the space required for the device during use.

[0032] Step 3: The operator installs clamping plate 1 6 and clamping plate 2 9 at the bottom of the base 2. The track is clamped by clamping plate 1 6 and clamping plate 2 9. The rubber pads 10 on the outside of clamping plate 1 6 and clamping plate 2 9 increase the friction of the track to prevent the base 2 from shaking during operation and to prevent the connection between the spiral spike and the concrete from shaking. The clamping plate 1 6, clamping plate 2 9 and the two sides of the base 2 are fastened by fasteners 11.

[0033] Step 4: Place the base 2 with the spiral spike on the corresponding anchor hole of the sleeper. After the lower thread of the spiral spike matches the reserved hole in the concrete, the grout solidifies. When the base 2 is moved vertically upward by the handle 1, the strong magnet 14 releases its adsorption on the top of the sleeper spike and removes the base 2.

[0034] Therefore, the above-disclosed embodiments are merely illustrative in all respects and are not the only ones. All modifications within the scope of this utility model or its equivalents are included in this utility model.
