Description

Technical Field

[0001] The utility model relates to the technical field of railway construction, in particular to a traction device for traction of railway support layer cut blocks out of a groove. Background Art

[0002] Railway track slabs are components used to support and secure rails, distributing the loads transmitted by trains through the rails to the underlying support structure. Beneath the track slabs lies a support layer, typically a concrete structure. This layer improves track stability and reduces noise. It also distributes the load on the track, preventing slab deflection and improving track flatness and stability.

[0003] However, under long-term stress working conditions and environmental changes, the supporting layer will become damaged, so it needs to be replaced. Generally, the supporting layer is cut into blocks, and then the supporting layer is pushed out from under the track plate using a pushing device. However, in actual construction, it is often encountered that the pushing device cannot be set up, which makes it difficult to replace the supporting layer and affects the construction period. Summary of the Invention

[0004] The purpose of the utility model is to provide a traction device for traction of railway support layer cut blocks out of a groove in view of the problems existing in the prior art.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0009] The railway support layer cutting and traction traction device can be installed and constructed on the outside of the railway without occupying multiple lines on the railway, which can reduce the impact on adjacent lines and has low requirements on the environment around the construction. It is particularly suitable for situations where there is no access to large-scale equipment and open construction sites in the field.

[0010] The traction frame and the traction beam can form a triangular support position on one side of the track plate, and the traction limit stack is used to form a connection anchor point, so that the traction equipment can be installed there while providing stable and firm support conditions.

[0011] Furthermore, the traction frame is arranged vertically, and the traction beam is one or more traction beams arranged horizontally.

[0012] Furthermore, the traction frame is a trapezoidal structure, including a bottom beam and a top beam, and a pair of side beams connecting the top beam and the bottom beam.

[0027] like Figures 1 to 4 As shown, a traction device for pulling blocks out of a railway supporting layer is provided, comprising a traction frame 7 and a traction beam 8. The traction frame 7 is arranged on a fixed foundation on one side of the supporting layer 2. One end of the traction beam 8 is mounted on the track plate 1 above the supporting layer, and the other end of the traction beam 8 is mounted on the traction frame 7 and extends out of the traction frame for a certain distance. A traction limit stack 9 is provided on the traction beam 8, and the traction beam 8 and the traction limit stack 9 are used to connect a traction device 12.

[0028] The traction device for pulling the cut pieces of railway supporting layer out of the groove has a simple structure, is easy to install and use, and can be conveniently coordinated with the traction equipment to pull or extract the cut pieces of supporting layer from under the track plate, thus overcoming the problem that the supporting layer is difficult to remove when it is not suitable to push it out of the groove. In addition, the device has the advantages of easy manufacture, low cost and easy assembly and disassembly.

[0029] The railway supporting layer cut blocks are pulled out of the groove by the traction device because of its easy disassembly and assembly and simple structure, which makes it very convenient to set up beside the railway, helping to improve construction efficiency and ensuring that the supporting layer cut blocks (usually 6 blocks) with a longitudinal length of more than 1m can be smoothly pulled out of the groove within a limited time at the same skylight point.

[0030] The railway support layer cutting and traction traction device can be installed and constructed on the outside of the railway without occupying multiple lines on the railway, which can reduce the impact on adjacent lines and has low requirements on the environment around the construction. It is particularly suitable for situations where there is no access to large-scale equipment and open construction sites in the field.

[0031] The traction frame 7 and the traction beam 8 can form a triangular support position on one side of the track plate, and the traction limit stack 9 is used to form a connection anchor point, so that the traction equipment can be installed there, and stable and firm support conditions are provided at the same time; after one end of the traction equipment is connected to the traction beam and the traction limit stack, the other end can be connected to the side wall of the supporting layer, and the supporting layer can be pulled out of the groove under the traction of the traction equipment. The traction chain of the traction equipment is oblique. Although it is oblique, it can provide a horizontal traction component. The horizontal traction component can be used to pull the supporting layer. Since the track plate is stationary, the support beam is also relatively fixed, which can suppress the vertical component without allowing the supporting layer to move up during the traction process.

[0032] The traction beam 8 extends out of the traction frame 7, which is convenient for connecting the traction equipment on the outside of the traction frame. On the one hand, it is convenient for connecting the traction equipment, and on the other hand, it can extend the horizontal distance between the traction equipment and the track plate. Such a setting can make the horizontal component of the traction equipment larger, making it easier to pull the supporting layer out of the groove.

[0033] Furthermore, the traction frame 7 is arranged vertically, and the traction beam 8 is arranged horizontally, so as to form a horizontal and vertical support structure, which is more stable than an acute angle or an obtuse angle; the traction beam can also be multiple, and the traction limit stack can also be multiple, so that anchor points at multiple positions can be formed, making it selective.

[0034] Furthermore, the traction frame 7 is a trapezoidal structure, including a bottom beam 701 and a top beam 702, and a pair of side beams 703 connecting the top beam 702 and the bottom beam 701. The bottom beam 701 is supported on the fixed foundation, and the top beam 702 supports the traction beam 8. The length of the top beam 702 is greater than the width of the traction beam 8.

[0035] The traction frame 7 with an isosceles trapezoidal structure can increase the support area and support stability, and can also allow sufficient space under the top beam to allow the traction equipment or lifting belt to pass through, and provide operational space; the triangular support frame is not used because the space at the upper corner of the triangular support frame is too small, which is not convenient for supporting the traction beam, nor for setting up and operating the traction equipment.

[0036] Furthermore, the traction beam 8 is connected to the traction frame 7 by bolts or welding, which can form a relatively stable connection relationship.

[0037] Furthermore, an anchor plate 10 is provided between the traction beam 8 and the track plate 1 , and the traction beam 8 and the anchor plate 10 are fixed to the track plate 1 by a plurality of anchor bolts 11 .

[0038] The connection method of the anchor plate 10 and the anchor bolt 11 is adopted, which is convenient for loading and unloading and can provide sufficient anchoring strength; the setting of the anchor plate 10 can also fine-tune the support height and horizontal relationship of the traction beam 8.

[0039] In this embodiment, the traction beam 8 is an I-beam with a length of about 3m. The traction frame 7 is welded by multiple square tubes. The size of the anchor plate 10 is 200*200*10mm. The anchor bolt 11 is an M12*160mm chemical anchor bolt with an anchoring depth of 110mm.

[0040] Furthermore, the fixed foundation is a hard road surface on one side of the railway, or a trench cover 6 of a side ditch 5. If there is a flat hard road surface (concrete floor) on the side of the railway, it is preferred to choose such a hard road surface to support the traction frame. If such a condition is not available (many outdoor railway sides do not have a clear flat hard road surface), the traction frame can be directly placed on the trench cover of the side ditch to stably support the traction frame.

[0041] Furthermore, a leveling pad is provided below the traction frame 7, and the leveling pad can be used to fine-tune the horizontality and height. The traction frame can be placed directly without setting up connectors for fastening.

[0042] Furthermore, the traction limiter 9 is a limit protrusion provided above the traction beam 8. The limit protrusion can be used to limit the position of the hanging lifting belt, and the other end of the lifting belt is connected to the hanging hook of the traction device. In some embodiments, if the operating space allows, the limit pull ring below the traction beam can also be used to directly connect the limit pull ring to the hanging hook of the traction device.

[0043] Furthermore, the traction equipment 12 is a DHS electric chain hoist or a HSZ0.5-30 hand chain hoist.

[0044] One way to use the railway support layer cut block traction trough traction device is as follows:

[0045] Before installing and using this device, the supporting layer to be replaced needs to be cut into pieces to separate it from the track plate and the structure below, and then a space for the supporting layer to be pulled out is chiseled out on the shoulder closure layer 4 on one side of the supporting layer 2, that is, a chiseled shoulder closure layer 3 is formed on the shoulder closure layer 4.

[0046] During installation, the support point is selected according to the actual situation of the construction site, the traction frame 7 is placed stably on the trench cover 6, an I-beam is taken as the traction beam 8, and it is erected on the traction frame 7 and the track plate 1, and an anchor plate 10 is set at the overlap of the traction beam 8 and the track plate 1, and it is fastened to the track plate 1 through four anchor bolts 11; the traction beam 8 and the traction frame 7 can be bolted or welded; after the erection is completed, a traction device 12 and a lifting belt are taken, the lifting belt is wrapped around the traction beam 8 and limited by the traction limit stack 9, the bottom of the lifting belt is connected to the hook of the traction device 12, and the traction hook of the traction device is connected to the traction point of the side wall of the supporting layer 2.

[0047] After the connection is completed, the debugging is carried out, and the traction is started after it is correct. The traction equipment will gradually pull the supporting layer blocks out from under the track plate. When the traction of one supporting layer block is completed, it moves to the position to continue the traction of the next supporting layer block.

[0048] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
