JP5779036B2 - Manual transport cart for track - Google Patents

Description

  The present invention relates to a track-use hand cart used to transport equipment by traveling on rails at an accident site, for example.

  Needless to mention a specific example, there are track carts (for example, Patent Document 1) and equipment transporting cat vehicles that transport equipment, and the former is a dedicated wheel that rolls on the rail on both the front and rear sides. By using this, it is possible to smoothly move on the rail, and has the advantage of having a loading capacity. Moreover, since the latter is lightweight, there exists an advantage that a line work is easy.

  However, all of these must arrive at the site, enter the railroad track from a railroad crossing, etc., place the track (mounted on wheels on the rails), load the equipment, and transport it to the appropriate location on the site. In other words, since the wheel is configured to roll on the rail exclusively until it is loaded from the place where the vehicle is transported by a truck or the like, it must be held and carried by the hand, which hinders movement on the ground. I was coming.

  The present invention pays attention to the disadvantages of such conventional examples, and provides a hand-carried vehicle for a track that can be moved on a track (railroad track) or on the ground (land) without any trouble, and is easy to use. It was created for the purpose of doing.

This is a manual track carriage that travels on rails and transports equipment, and has an inner wheel for ground travel and an outer wheel for rail travel on both the left and right sides of the loading platform equipped with a handle for manual operation. The outer wheels are coaxial with each other and provided at a separation distance shorter than the width of the head of the rail, and the inner wheel is idled while being positioned in a gauge when the outer wheel rolls on the rail. It is composed of a tire having a diameter larger than that of the wheel, and the outer circumferential surface of the outer wheel is provided with a recessed hole, and on the support body supported in the vicinity of one wheel body on the rear side of the loading platform, A brake device is provided for braking or releasing the outer wheel by supporting a braking piece that moves forward and backward by operation and engaging and disengaging the braking piece with a recessed hole arranged in a circumferential surface of the outer wheel. Is resistant to the spring device provided on the support by operating the operating piece. By releasing the braking piece from the recessed hole, the braking state of the outer wheel is released, and by releasing the fingertip from the operating piece, the braking piece is engaged with the appropriate recessed hole by the spring device. The rolling of the outer wheel is restricted.

  According to the present invention, since only the inner wheels formed of tires roll on the ground when moving on the ground, they can move on the ground without hindrance, and are independent from each other on the left and right sides before and after the loading platform. Since there are inner wheels that are tires in the state, it is possible to provide a transport cart with easy direction control.

  Also, when traveling on a track (rail), the inner wheel is in the gap and acts as a flange to prevent derailment of the outer wheel, so that a roller body without a flange can be applied as a wheel and is inexpensive in cost. Products can be provided.

In addition, since it can move without any inconvenience to any of the railroads, carry the necessary equipment while pre-loaded on the site, move on the land using the inner wheels, which are rubber wheels, after arrival at the site (usually until the railroad crossing), This makes it possible to place the same equipment on top of each other, and to carry the equipment quickly on the track in the event of an emergency, which is practically effective. Further, on the peripheral surface of the outer wheel, while the concave holes are arranged in a row, the support body supported in the vicinity of one wheel body on the rear side of the cargo bed is supported by the braking piece that moves forward and backward by the operation of the interlocking wire, A brake device that brakes or releases the outer wheel by disengaging the brake piece with a concave hole arranged in the peripheral surface of the outer wheel is provided, and the brake device operates the operation piece on the support body. By releasing the braking piece from the recessed hole against the provided spring device, the braking state of the outer wheel is released, and by releasing the fingertip from the operation piece, the braking piece is engaged with the appropriate recessed hole by the spring device. Since the configuration is such that the rolling of the outer wheel is restricted, even when the track manual transport cart according to the present invention is left on the rail, the track manual transport cart can be prevented from running away due to the action of the brake device.

  The drawings show an embodiment of the track-type hand cart according to the present invention. The track-type hand cart A according to the embodiment includes a loading platform 2 to which a handle 1 for manual operation is detachably attached, and front and rear surfaces of the loading platform 2. The wheel bodies 3, 3, 3, and 3 are provided on the left and right sides, respectively.

  The loading platform 2 is composed of a grid body in which the horizontal beam 2a and the vertical beam 2b are welded to each other, and upright portions 2w and 2w ′ are relatively provided at both front and rear ends. The transporting equipment L placed between the transporting equipment L can be securely held and transported regardless of the size of the transporting equipment L so that the rope is hooked on the horizontal rail 2a or the vertical rail 2b.

  Further, a case-like attachment portion 4 having an upper surface opening is provided in the center portion in the width direction of the rear end side upright portion 2w ′ of the loading platform 2, and the attachment portion 4 has a T-shaped leg collar portion 1a and a handle in front view. The leg 1a of the manual operation handle 1 composed of the portion 1b is inserted, the tip of the fastening bolt 5 screwed to the mounting portion 4 is operated from the outside, and the leg 1a is tightened to be detachable. It can be fixed to.

  The wheel body 3 is provided with an axle 7 between support portions 6b, 6b of a support frame 6 formed by providing support portions 6b, 6b relative to each other on both sides of an attachment portion 6a. 8 and the outer wheel 9 are rotatably supported.

  The wheel bodies 3 are disposed by welding attachment portion pieces 6a of the support frame 6 to the left and right sides of the front and rear end portions of the lower surface of the underframe 1, and the positions of the wheel bodies 3 are located outside the wheel bodies 3. When the wheel 9 is placed on the rail R, the inner wheels 8 are positioned adjacent to the outer wheel 9 in the gauge S of the rail R (FIG. 5).

  As shown in FIG. 4, the inner wheel 8 of the embodiment is configured by assembling a tire (rubber) 8a to a wheel rim 8b, and is fitted into a sleeve (slide bearing) 10 fitted to the axle 7 from the outside. It is a thing. The outer wheel 9 is made of a hard synthetic resin roller body and is attached to the axle 7 via a bearing (rolling bearing) 11.

  The inner and outer wheels 8 and 9 rotate freely coaxially with each other (axle 7), the inner wheel 8 has a larger outer diameter than the outer wheel 9, and when the outer wheel 9 rolls on the rail R, the inner wheel 8 is idle without being grounded (FIG. 5), and when the inner wheel 8 is grounded and rotated on the tread surface, the outer wheel 9 is not grounded (FIG. 6).

  Further, the inner wheel 8 is arranged in the gap S between the rails R and R so as to be adjacent to the rail R, and the separation distance along the axle 7 with the outer wheel 9 is larger than the lateral width of the head portion Ra of the rail R. It is shortened. As a result, the inner wheel 8 serves as a flange of the outer wheel 9 and is prevented from being removed from the rail R.

  The axle 7 is constituted by a bolt body in which a nut 7b is screwed between the support pieces 6a and 6a of the support frame 6, which is easy to replace the outer wheels 8 and 9 due to damage due to aging. Therefore, if the response to the change over time of the wheels 8 and 9, that is, the exchange is ignored, the support piece 6a, 6a may be a rod rod.

  And after transporting to the site by truck, etc., down to the ground, loading the necessary equipment (articles) L, moving on the ground using the inner wheels 8 to the entry point (railway etc.) of the track (track), The outer wheel 9 is mounted on the rail R, moved to the site using the wheel 9, and used to transport the equipment L (necessary on the loading platform 2 at the storage location of the transport vehicle A). In the event of a derailment accident, for example, equipment such as tools necessary for repair can be loaded, and when an accident report is received, it can be loaded directly onto the truck and taken directly to the site. ).

  Reference numeral 20 shown in FIG. 6 denotes a brake device. The brake device 20 is a brake that advances and retreats by operating the interlocking wire 202 on a support body 201 supported in the vicinity of one wheel body 3 on the rear side of the loading platform 2. A concave hole (not shown) for supporting the piece 203 is arranged on the peripheral surface of the outer wheel 9, and the rear end of the interlocking wire 202 having the tip connected to the brake piece 203 is a leg.
