Description

[Technical Field]

[0001] The present invention relates to a track equipment lifting device for lifting track equipment such as rails, sleepers, and rail fastening devices. [Background technology]

[0002] Conventionally, for example, a crossing device has been used as a lifting device for track equipment such as rails and sleepers (see, for example, Patent Document 1). A crossing device is a lifting device for track equipment that has a running girder placed on a pair of support legs spaced apart by a distance greater than the width between the rails, a chain block or the like attached to the running girder, and uses the chain block or the like to lift and move the rail. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Utility Model Publication No. 3184462 Summary of the Invention [Problem to be solved by the invention]

[0004] However, the mountain crossing device described in Patent Document 1 uses a running girder that crosses the tracks, so the entire device is relatively large, requiring a large space for storage and transportation, and multiple workers for installation.

[0005] Furthermore, when a manual chain block is used as the lifting mechanism, there is also the problem of poor workability.

[0006] Therefore, the present invention was made with an eye on such problems, and aims to provide a track equipment lifting device that can be made compact without using running girders that cross the tracks, and that can improve workability by lifting and moving track equipment without using chain blocks or the like. [Means for solving the problem]

[0007] In order to solve the above problem, the track equipment lifting device of the present invention is characterized by comprising: a carriage having a support pillar attached to the top of the carriage body that runs on rails; a horizontal rotation part that is rotatably attached to the top of the support pillar of the carriage and has a horizontal shaft part that extends horizontally; a hanging bar that has a hanging part for hanging track equipment attached to its tip end and a hanging bar side connected part attached to its rear end, and has a hanging bar side horizontal shaft hole part between its tip end and rear end that is rotatably connected to the horizontal shaft part of the horizontal rotation part; and a lever handle that has a handle side horizontal shaft hole part rotatably connected to the horizontal shaft part of the horizontal rotation part and a handle side connecting part that is connected to the hanging bar side connected part of the hanging bar. Furthermore, in the track equipment lifting device of the present invention, the hanging bar side connected portion of the hanging bar has a plurality of angle setting holes into which angle setting pins are inserted, which are provided at predetermined angles on a circumference drawn with a predetermined radius centered on the hanging bar side horizontal axis hole, while the handle side connecting portion of the lever handle has an angle setting pin hole into which the angle setting pin is inserted, and is configured so that the angle of the lever handle relative to the hanging bar can be changed by aligning one of the plurality of angle setting holes in the hanging bar side connected portion of the hanging bar with the angle setting pin hole in the handle side connecting portion of the lever handle and passing the angle setting pin through it. In addition, the track equipment lifting device of the present invention is also characterized in that the tip of the lifting bar has multiple lifting part mounting holes at a predetermined interval for attaching the lifting part. In addition, in the track equipment lifting device of the present invention, the lever handle comprises a rod-shaped handle body and a handle-side connecting part that is detachably attached to the tip of the handle body, and the handle-side connecting part is characterized by having a handle body insertion part that is inserted into the tip of the handle body, and a pair of connecting support pieces that are provided on the tip side of the handle body insertion part and have the handle-side horizontal shaft hole part that is inserted with the horizontal shaft part and is connected so as to be rotatable in the vertical direction, and an angle setting pin hole part that has inserted therein an angle setting pin that is connected to one of the multiple angle setting holes of the hanging bar side connected part of the hanging bar. The track equipment lifting device according to the present invention is also characterized in that the carriage is provided with a rail fixing mechanism for fixing it to the rail on which it runs. [Effects of the Invention]

[0008] In the track equipment lifting device of the present invention, a lifting bar having a lifting part at its tip for lifting track equipment and a lever handle held by an operator are connected to the horizontal axis of the horizontal rotating part at the top of the support column provided on the trolley so as to be rotatable in the vertical direction, and the handle side connecting part of the lever handle is connected to the lifting bar side connecting part of the lifting bar. Therefore, by grabbing the lever handle and moving it up and down, a worker can use the so-called principle of leverage to lift the track equipment suspended by the suspension part at the tip of the suspension bar, and by rotating the lever handle horizontally via the horizontal rotation part, the track equipment suspended by the suspension part can be moved horizontally. As a result, the entire device can be made smaller because no running girders are used, and track equipment can be lifted using the principle of leverage by connecting the lever handle and the lifting bar without using a chain block, and then rotated using the horizontal rotating part of the support pillar to move it inside and outside the track, improving workability.

DETAILED DESCRIPTION OF THE INVENTION

[0010] Hereinafter, a railway equipment lifting device 1 according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings. Note that the embodiment described below is merely an example of the present invention, and the present invention is not limited to the following embodiment, and can be modified as appropriate within the scope of the technical concept of the present invention.

[0011] <Configuration of the railway equipment lifting device 1 according to the embodiment> The railway equipment lifting device 1 of the embodiment is a device used to lift railway equipment that is difficult to move by human power, such as rails, sleepers, and rail fastening devices, and as shown in Figures 1 and 2, is configured with a bogie 11, a horizontal rotating part 12, a lifting bar 13, a lifting part 14, a lever handle 15, etc.

[0012] (Cart 11) As shown in Figures 3 and 4, the bogie 11 is composed of a bogie body 11a that runs on a track rail (hereinafter referred to as the rail) R, a cylindrical support 11b erected on the top of the bogie body 11a, and a rail fixing mechanism part 11c for fixing the bogie 11 to the rail R on the track.

[0013] The carriage body 11a has rollers (wheels) 11a1, 11a1 attached to the front and rear via roller support parts 11a2, 11a2, respectively, and a rail fixing mechanism part 11c for fixing the carriage body 11a to the rail R is provided closer to the center than the roller support parts 11a2, 11a2.

[0014] The support pillar 11b is a hollow steel pipe whose lower end is erected on the bogie body 11a, and has a support pillar body 11b1 having a hollow portion 11b11 into which a rotating shaft portion 12a (described later) of the horizontal rotating portion 12 is inserted, and a disk-shaped support portion 11b2 provided at the upper end of the support pillar body 11b1 and rotatably supporting a circular seat portion 12b1 (described later) of the horizontal rotating portion 12, which can rotate horizontally.

[0015] The rail fixing mechanism 11c fixes the carriage 11 to the rail R, and is made up of a fixed rail engaging portion 11c1, a rotating rail engaging portion 11c2, rail engaging shaft bolts 11c3, 11c3, and engaging portion fixing pins 11c4, 11c4.

[0016] The fixed rail engagement portion 11c1 is fixed to one side of the carriage body 11a, for example, the upper side in Figure 3(a), and is a rail engagement portion that is provided with an engagement portion fixing pin insertion hole 11c11 (see Figure 4(b)) into which the engagement portion fixing pins 11c4, 11c4 are inserted, and is formed in an L-shape so as to engage with one side of the rail R.

[0017] The swivel rail engagement portion 11c2 is rotatably connected to the other side of the carriage body 11a, which is the side opposite the fixed rail engagement portion 11c1, for example, the lower side in Figure 3(a), via rail engagement shaft bolts 11c3, 11c3, and is provided with an engagement portion fixing pin insertion hole 11c21 (see Figure 4(b)), and is a rail engagement portion formed in an L-shape so as to engage with the other side of the rail R by rotating.

[0018] The rail engagement shaft bolts 11c3, 11c3 are bolts that rotatably connect the fixed rail engagement portion 11c1 and the rotating rail engagement portion 11c2.

[0019] The engagement portion fixing pins 11c4, 11c4 are fixing pins used to fix the fixed rail engagement portion 11c1 and the rotatable rail engagement portion 11c2, and are configured so that their tips are bent to prevent them from coming loose. When the engagement portion fixing pins 11c4, 11c4 are removed as shown in Figure 4(b), the rotatable rail engagement portion 11c2 becomes free, making it possible to remove the trolley 11 from the rail R. On the other hand, when the engagement portion fixing pin insertion hole 11c11 of the fixed rail engagement portion 11c1 is aligned with the engagement portion fixing pin insertion hole 11c21 of the rotatable rail engagement portion 11c2 and the engagement portion fixing pin insertion hole 11c21 is inserted, the trolley 11 can be fixed to the rail R.

[0020] (horizontal rotation part 12) As shown in Figures 5(a) to (c), the horizontal rotation section 12 is configured to include a rotation shaft section 12a that is inserted into a hollow section 11b11 at the center of a support main body 11b1 that is erected on the cart main body 11a and rotates horizontally, and a horizontal shaft support section 12b that is provided on the upper part of the rotation shaft section 12a and supports both sides of a horizontal shaft section 12c that extends horizontally perpendicular to the support 11b.

[0021] The rotation shaft portion 12a is made of a cylindrical steel pipe having an outer diameter that is approximately the same as or slightly smaller than the inner diameter of the hollow portion 11b11 at the center of the support body 11b1.

[0022] The horizontal shaft support portion 12b is composed of a disk-shaped circular seat portion 12b1 that is provided at the upper end of the rotating shaft portion 12a and has an outer diameter larger than the inner diameter of the hollow portion 11b11 at the center of the pillar main body 11b1, and a pair of horizontal shaft support upright portions 12b2, 12b2 that stand upright from the upper surface of the circular seat portion 12b1 and support both sides of the horizontal shaft portion 12c, and the pair of horizontal shaft support upright portions 12b2, 12b2 are provided with shaft insertion holes 12b3, 12b3 through which the horizontal shaft portion 12c passes.

[0023] 5(b), the horizontal shaft portion 12c is formed by a rail-engagement shaft bolt that is inserted into and connected to shaft portion insertion holes 12b3, 12b3 of a pair of horizontal shaft support upright portions 12b2, 12b2 of the horizontal shaft support portion 12b, a hanger bar-side horizontal shaft hole 13c (described later) of the hanger bar 13, and a handle-side horizontal shaft hole 15b21 (described later) of the lever handle 15, and moves the hanger bar 13 and the lever handle 15 up and down in the vertical direction around the horizontal shaft portion 12c as a rotation center. Note that the horizontal shaft portion 12c is fastened with a nut 12d (see FIG. 5(b)) or the like to prevent it from falling off the shaft portion insertion holes 12b3, 12b3.

[0024] (Hanging bar 13) As shown in Figures 6(a) to (c), the hanging bar 13 has a long, thin, plate-shaped hanging bar main body 13a and a fan-shaped hanging bar side connected portion 13b that is continuous with the rear end of the hanging bar main body 13a.At the boundary between the hanging bar main body 13a and the hanging bar side connected portion 13b, there is provided a hanging bar side horizontal shaft hole portion 13c through which the horizontal shaft portion 12c of the horizontal rotating portion 12 passes and which is connected so as to be rotatable in the vertical direction.

[0025] The hanging bar body 13a has, for example, three hanging part mounting holes 13a1 spaced at predetermined intervals as shown in Figures 6(b) and (c), and the weight when operating the lever handle 15 can be changed by changing the mounting position of the hanging part 14 according to the weight of the track equipment being hung by the hanging part 14.

[0026] The suspension bar side connected portion 13b is formed in a fan shape as shown in Figure 6(b), and is provided with a plurality of angle setting holes 13b1 (for example, five in this embodiment) provided at predetermined angle intervals on a circumference drawn with a predetermined radius around the suspension bar side horizontal shaft hole 13c, and the mounting angle of the lever handle 15 with respect to the suspension bar 13 can be changed by selecting one of the plurality of angle setting holes 13b1, aligning it with an angle setting pin hole 15b22 of the lever handle 15 described later, and passing an angle setting pin 13d through it.

[0027] Here, as shown in Fig. 6(b), the plurality of angle setting holes 13b1 (for example, five in this embodiment) of the suspension bar side connected portion 13b are arranged in a straight line with the three suspension portion mounting holes 13a1 and the suspension bar side horizontal shaft hole 13c so that at least one angle setting hole 13b1 between the suspension bar 13 and the lever handle 15 is 180 degrees, which is the largest angle, and the other four angle setting holes 13b1 are arranged so that the angle between the suspension bar 13 and the lever handle 15 is less than 180 degrees but equal to or greater than 90 degrees. In other words, the angle of the lever handle 15 relative to the suspension bar 13 can be set between 180 degrees and 90 degrees by the plurality of angle setting holes 13b1 (for example, five in this embodiment) of the suspension bar side connected portion 13b.

[0028] (Hanging part 14) The suspending part 14 is composed of a shackle 14a, a suspending belt 14b, a hook 14c with a spring to prevent it from coming loose that is connected to the lower end of the suspending belt 14b, and a suspending fitting 14d, etc., and the suspending fitting 14d is selected to be the most suitable fitting depending on the railroad equipment to be hoisted and moved.

[0029] As shown in FIG. 7(a), the shackle 14a is a well-known fastener that is composed of a U-shaped shackle body 14a1 and a screw pin 14b that passes through an opening in the shackle body 14a1 to close the opening.

[0030] The suspension belt 14b is a well-known belt in which a cover made of nylon or the like is placed on the outside of a metal chain (not shown) or the like, as shown in FIG. 7(b).

[0031] The hook 14c with anti-detachment spring is a well-known hook having a hook body 14c1 with a connecting hole 14c11 through which the hanging belt 14b etc. is passed, as shown in Figures 7(c) and (d), and an anti-detachment spring 14c2 which is always biased and prevents the hook from coming off when hooked onto the hook body 14c1.

[0032] The hoisting fixture 14d is a hoisting fixture for hoisting and moving a railroad track equipment such as a guardrail R' having an L-shaped cross section, and is composed of a hoisting fixture main body 14d1 and a receiving base 14d2.

[0033] As shown in Figures 8(a) to (e), the hanging hardware main body 14d1 is provided with a hook hole 14d11 into which the hook main body 14c1 of the hook 14c with anti-detachment spring is hooked, and a fitting portion 14d12 into which one piece of the guardrail R' with an L-shaped cross section fits, and is also composed of a pendulum plate 14d14 that rotates around a rotation axis 14d13 to prevent the attachment / detachment and fall of the guardrail R' with an L-shaped cross section that is the object to be lifted.

[0034] Receiving base 14d2 is attached to the bottom of hanging fitting main body 14d1 by welding or the like, and is a base that receives the other piece of guardrail R' with an L-shaped cross section that does not fit into fitting portion 14d12 of hanging fitting main body 14d1. Note that, although receiving base 14d2 is attached to the bottom of hanging fitting main body 14d1 by welding or the like here, it may of course be configured as a separate body from hanging fitting main body 14d1 and configured to be separable from hanging fitting main body 14d1 by connection with bolts and nuts (not shown) or the like.

[0035] (lever handle 15) As shown in Figures 9(a) to (c), the lever handle 15 is composed of a rod-shaped handle main body 15a, a handle side connecting part 15b that is detachably attached to the tip of the handle main body 15a, a retaining pin 15c, etc.

[0036] The handle body 15a is a rod or pipe that is grasped by the operator, and has a pin hole 15a1 at its tip into which a retaining pin 15c is inserted when the handle side connecting part 15b is attached.

[0037] The handle side connecting portion 15b is composed of a handle body insertion portion 15b1 that is inserted into the tip portion of the handle body 15a, a handle side horizontal shaft hole portion 15b21 that is provided on the tip side of the handle body insertion portion 15b1 and into which the horizontal shaft portion 12c is inserted and which is connected so as to be rotatable in the vertical direction, and a pair of connecting support pieces 15b2, 15b2 that are provided with an angle setting pin hole portion 15b22 into which an angle setting pin 13d that is connected to one of the multiple angle setting hole portions 13b1 of the hanging bar side connected portion 13b of the hanging bar 13 is inserted.

[0038] <Method of using the railway equipment lifting device 1 of the embodiment> Next, a method of using the railway equipment lifting device 1 of the embodiment configured as above will be described.

[0039] Figure 10 is a front view showing a state in which two track equipment lifting devices 1 of the embodiment are used to lift, for example, a guardrail R' outside rails R, R on the track, and Figure 11 is a plan view showing this state.

[0040] 10 and 11, when moving the guardrail R', in order to lift both longitudinal ends of the guardrail R', first, each of the two track equipment lifting devices 1,1 of embodiment 1 is moved by running on the rail R, and after each reaches a target point such as both ends of the guardrail R', the rail fixing mechanism 11c,11c of each track equipment lifting device 1,1 is operated to fix it to the rail R. Specifically, the engagement portion fixing pin insertion hole 11c11 (see FIG. 4(b)) of the fixed rail engagement portion 11c1 of the rail fixing mechanism 11c is aligned with the engagement portion fixing pin insertion hole 11c21 (see FIG. 4(b)) of the rotating rail engagement portion 11c2, and each track equipment lifting device 1 is fixed to the rail R through the engagement portion fixing pin 11c4.

[0041] Next, as shown in Figs. 10 and 11, adjustments are made according to the body size, such as the height, of the operator who will operate each of the railway equipment lifting devices 1, 1.

[0042] In other words, the angle of the lever handle 15 relative to the lifting bar 13 is changed to an optimum angle for each worker depending on the body size, such as the height, of the worker who operates each of the left and right track equipment lifting devices 1, 1, so that the angle of the lever handle 15 that allows each worker to operate it easily, i.e., the height of the lever handle 15, is adjusted.

[0043] For example, as shown in Figures 10 and 11, if the worker W on the left side is larger than the worker W' on the right side, the larger worker W on the left side will insert the angle setting pin 13d into, for example, the uppermost angle setting hole 13b1 of the five angle setting holes 13b1 of the hanging bar side connected part 13b of the hanging bar 13 and the angle setting pin hole 15b22 of the lever handle 15, as shown in Figures 10 and 12, to connect the hanging bar 13 and the lever handle 15.

[0044] In contrast, the smaller worker W' on the right side inserts the angle setting pin 13d into, for example, the second angle setting hole 13b1 from the top out of the five angle setting holes 13b1 in the connected portion 13b on the hanging bar side of the hanging bar 13 and the angle setting pin hole 15b22 in the lever handle 15, as shown in Figures 10 and 13.

[0045] This means that even when workers W, W' of different body sizes, such as height, cooperate to lift and move using the track equipment lifting devices 1, 1, it is possible to insert the angle setting pin 13d into the angle setting hole 13b1 with the optimal angle out of the five angle setting holes 13b1 in the lifting bar side connected part 13b of the lifting bar 13 and the angle setting pin hole 15b22 of the lever handle 15, thereby connecting the lifting bar 13 and the lever handle 15, thereby improving work efficiency in this respect as well.

[0046] After the setting is completed according to the extension of the workers W, W' who operate the left and right track equipment lifting devices 1, 1, respectively, both ends of the guardrail R' are fixed and lifted using the lifting fittings 14d of the lifting devices 14 attached to the lifting portion mounting holes 13a1 at the ends of the lifting bars 13 of each track equipment lifting device 1, 1.

[0047] In this case, one guardrail R' is lifted and moved using two track equipment lifting devices 1,1, so in principle, the lifting devices 14 should be installed in the same lifting part mounting hole 13a1 out of the multiple lifting part mounting holes 13a1 (see Figure 6(b) etc.) on the lifting bars 13,13 of the two track equipment lifting devices 1,1.However, if there is a difference in strength between the workers operating the two track equipment lifting devices 1,1, the lifting force can also be adjusted using the principle of leverage by installing the lifting devices 14 in different lifting part mounting holes 13a1.

[0048] Furthermore, the handle body 15a of the lever handle 15 grasped by workers W, W' is configured to be detachable from the handle side connecting part 15b by removing the connecting pin 15c, so if there is a difference in strength between the workers operating the two track equipment lifting devices 1, 1, it is of course possible to remove the handle body 15a from the handle side connecting part 15b and replace it with a handle body 15a of the optimal length.

[0049] Then, after each worker W, W' has lifted the long guardrail R' by operating the track equipment lifting device 1, 1 that has been adjusted to the optimum state according to their physique, etc., the handle body 15a of the lever handle 15 that each worker W, W' is holding is pushed horizontally as synchronously as possible.

[0050] Since the lever handle 15 and lifting bar 13 of each track equipment lifting device 1,1 are each connected via the horizontal shaft portion 12c of the horizontal rotation portion 12 which is supported horizontally and rotatably on the support pillar 11b of the trolley body 11a, when each worker W,W' pushes the handle body 15a,15a of the lever handle 15,15 of each track equipment lifting device 1,1 horizontally, the lever handle 15,15 and lifting bar 13,13 rotate together around the support pillar 11b,11b, and can be moved horizontally, for example, from the outside of the rails R,R to the inside of the rails R,R.

[0051] Then, when each worker W, W' operating the two track equipment lifting devices 1, 1 raises the handle bodies 15a, 15a of the lever handles 15, 15 that they are holding, using the principle of leverage, they can lower the guardrail R' that is being lifted by the lifting devices 14, 14 attached to the lifting bars 13, 13, and easily move it in the vertical direction.

[0052] In the above explanation, two track equipment lifting devices 1 of the embodiment are used to lift and move long and heavy track equipment such as guardrails R', but the present invention is not limited to this. For example, when lifting and moving normal rails R that are heavier than guardrails R', three or more track equipment lifting devices 1 of the embodiment may be used for the work. Furthermore, when lifting and moving relatively light track equipment such as rail fastening devices and composite sleepers that are not as heavy and long as guardrails R', it is of course also possible to use only one track equipment lifting device 1 of the embodiment for the work. However, in these cases, the lifting hardware 14d for guardrail R' cannot be used, so the appropriate lifting hardware must be chosen to suit the track equipment to be lifted. For example, if it is a normal rail R, a lifting hardware for rail R must be used. If the object to be lifted is a rail fastening device or a synthetic sleeper, the rail fastening device must be directly hooked with the spring-equipped hook 14c to prevent it from coming loose, or the fastening device must be tied with a binding member such as a chain, rope, or wire (not shown), and the binding member must be hooked with the spring-equipped hook 14c to prevent it from coming loose, and then the object must be lifted.

[0053] In addition, if the track equipment being lifted by the track equipment lifting device 1 of the embodiment is not very heavy, it is possible to release the fixed rail engagement portion 11c1 and the rotating rail engagement portions 11c2, 11c2 of the rail fixing mechanism portion 11c, and allow the trolley 11 to run on the rail R while the track equipment is in the lifted state.

[0054] <Summary of the railway equipment lifting device 1 according to the embodiment of the present invention> As described above, in the track equipment lifting device 1 according to an embodiment of the present invention, the horizontal rotating section 12 at the upper end of the support 11b provided on the bogie 11 running on the tracks is connected to a lifting bar 13 having a lifting section 14 at its tip for lifting track equipment, and a lever handle 15 at its rear end configured to be grasped by an operator, so that they can rotate vertically, and the angle setting pin hole section 15b22 of the lever handle 15 is connected to the lifting bar side connected section 13b of the lifting bar 13 by an angle setting pin 13d.

[0055] Therefore, according to the track equipment lifting device 1 of the embodiment of the present invention, the entire device can be made smaller because it does not use a running girder like a mountain crossing device, and track equipment can be lifted using the so-called lever principle by connecting the lever handle 15 and the lifting bar 13 without using a chain block, and then rotated horizontally using the horizontal rotating part 12 of the support 11b to move it inside and outside the track, thereby improving the workability of track maintenance work.

[0056] In addition, in the railway equipment lifting device 1 of the embodiment of the present invention, the hanging bar side connected portion 13b of the hanging bar 13 has multiple angle setting hole portions 13b1 provided at predetermined angles on a circumference drawn with a predetermined radius centered on the hanging bar side horizontal shaft hole portion 13c.

[0057] Therefore, in the track equipment lifting device 1 of the embodiment of the present invention, the angle setting hole 13b1 with the angle most suitable for the worker is selected from the multiple angle setting holes 13b1 of the lifting bar side connected part 13b of the lifting bar 13, and is connected to the angle setting pin hole 15b22 of the lever handle 15 via the angle setting pin 13d, thereby making it possible to set the height of the lever handle 15 to an optimal angle according to the physique, such as the height, of the worker operating the track equipment lifting device 1, and in this respect too, the workability of track maintenance work can be improved.

[0058] In addition, in the railway equipment lifting device 1 of the embodiment of the present invention, the tip of the lifting bar 13 is provided with multiple lifting part mounting holes 13a1 arranged at a predetermined interval so as to change the mounting position of the lifting part 14.

[0059] Therefore, in the embodiment of the track equipment lifting device 1 according to the present invention, the track equipment is lifted using the principle of leverage, and depending on the weight of the track equipment to be lifted, it is possible to change the force applied to the lever handle 15 by changing the mounting position of the lifting part 14 by selecting one of the multiple lifting part mounting holes 13a1, thereby improving the workability of track maintenance work.

[0060] Furthermore, in the embodiment of the track equipment lifting device 1 according to the present invention, the lever handle 15 comprises a rod-shaped handle body 15a and a handle side connecting portion 15b detachably attached to the tip of the handle body 15a, and the handle side connecting portion 15b has a handle body insertion portion 151 inserted into the tip of the handle body 15a, and a pair of connecting support pieces 15b2, 15b2 provided on the tip side of the handle body insertion portion 15a1, into which the horizontal shaft portion 12c is inserted and which is connected so as to be rotatable in the vertical direction, and

[0061] Therefore, in the track equipment lifting device 1 of the embodiment of the present invention, not only can the angle between the lifting bar 13 and the lever handle 15 be changed according to the worker's height, etc., but the length of the lever handle 15 itself can also be changed by replacing the handle body 15a of the lever handle 15, which also improves the workability of track maintenance work.

[0062] Furthermore, in the track equipment lifting device 1 according to the embodiment of the present invention, in any one of the track equipment lifting devices described above, the carriage 11 is provided with a rail fixing mechanism 11c for fixing to the rail R on which it travels.

[0063] Therefore, in the embodiment of the track equipment lifting device 1 according to the present invention, after the track equipment lifting device 1 is fixed to the rail R by the rail fixing mechanism part 11c, it is possible to lift and move the track equipment using the principle of leverage, thereby improving safety when performing maintenance work such as lifting and moving rails and steel materials.

[0064] In the above embodiment, a configuration has been described in which a plurality of angle setting holes 13b1 are formed in a fan shape on the hanging bar side connected portion 13b of the hanging bar 13 at predetermined angles centered on the hanging bar side horizontal shaft hole 13c, and the attachment angle of the lever handle 15 to the hanging bar 13 is made changeable by aligning the position of the plurality of angle setting holes 13b1 on the hanging bar side connected portion 13b with the angle setting pin hole 15b22 on the lever handle 15 and passing the angle setting pin 13d through them. However, the present invention is not limited to this, and a configuration in which a single angle setting pin hole is provided on the hanging bar side connected portion 13b of the hanging bar 13, similar to the lever handle 15, may also be made in which the attachment angle of the lever handle 15 to the hanging bar 13 cannot be changed.

[0065] Furthermore, in the description of the above embodiment, it was explained that the attachment position of the hanging portion 14 can be changed by providing, for example, multiple hanging portion attachment holes 13a1 at a predetermined interval at the tip of the hanging bar main body 13a of the hanging bar 13, but the present invention is not limited to this, and it is of course also possible to provide only one hanging portion attachment hole 13a1 and configure the attachment position of the hanging portion 14 to be unchangeable.
