Abstract

PROBLEM TO BE SOLVED: To provide a device capable of saving workload and time in transporting and placing a concrete block while assuring safety of a worker in a carrying and placing step of a concrete block for ballast beds such as railway lines.SOLUTION: A hanger for carrying a concrete block integrally includes a two block attitude control mechanism and a taper pin with a lock-bar fixing groove with which the hanger can stably lift and carry two concrete blocks at one time in a delivery form, and set down the two blocks at one time.

Description

In the present invention, two blocks can be transported and moved simultaneously for securing a walking surface and stopping ballast outflow by connecting a plurality of blocks on the left and right sides and laying them on the roadbed such as railroad tracks. It relates to a hanging tool.

Concrete blocks for ballast road floors such as railway tracks have various structures such as L-shaped blocks and T-shaped blocks. This block is transported to the construction site via a number of processes, and more efficient and safe transport is required especially for work within a limited time at the construction site.

When installing concrete blocks for ballast roadbeds such as railway tracks, it must be done by personnel for a limited time. However, in an environment where large heavy machinery or the like cannot be used, it must be handled with human power. More efficient transportation and construction are required on the premise of safety.
In addition, because of the various shapes of concrete blocks according to the construction, the shape is unsuitable for transportation and lifting, which is not only very dangerous for the operator, but also involves the risk of material damage. In addition, it is important to prevent misplacement that the construction of the construction auxiliary member is integrated in the work withdrawal.

The concrete block suspension for the ballast roadbed has the following configuration in order to solve the above problems.
An integral suspension that can lift two blocks at the same time with minimal human power.
A structure that allows quick mounting and dismounting to the block and does not drop off.
It is possible to always maintain the horizontal balance and vertical posture of the two blocks during lifting movement.

In the concrete block for ballast roadbed, a drainage hole is structurally penetrating in the width direction of the block on the construction elevation surface. It is the first configuration of the present invention that the two blocks are lifted simultaneously as a set with restraint from the through hole and the back surface before construction.

With respect to stable posture control during lifting, the front and rear direction stability of the two blocks (FIG. 2 block front-rear direction Z) is a lock bar fixing groove installed at each angle part, rotating rod part and lower part of the lifting tool angle of the present invention. The second configuration of the present invention is that the vertical Y-position is stabilized by inserting the attached tapered pin into the drain hole.

Further, the horizontal separation collapse in the two-block longitudinal direction (FIG. 2 block longitudinal direction X) is prevented by connecting and fixing with a taper pin with a lock bar fixing groove and a pin removal prevention bar installed at the lower part of each angle of the hanging tool.
With the above configuration, the posture of the two blocks is always stable when lifting and moving, and the connecting and fixing by the taper pin with the lock bar fixing groove and the pin removal preventing bar is effective for preventing the block from falling. Three configurations are used.

Conveyance of concrete blocks for ballast roadbed, lifting movement in the construction process, and lifting work can be performed safely in a short time with minimal human power at the same time.
Embodiments according to the present invention will be described below with reference to the drawings.

1.1a, 1.1b, and 1.1c show structural examples of a single concrete block for ballast roadbed.
As shown in FIG. 2, the present invention is a hanger that can lift and convey the two blocks simultaneously.
As shown in FIGS. 3 and 3a, when the lifting tool of the present invention is attached to the two blocks of FIG. The taper pins are engaged with the lock bar to prevent the block from falling off.
FIG. 1 a shows a front view of the hanger body structure.
FIG. 1b is a side view of the hanger body structure.
Fig. 1.1a is a plan view of a single concrete block for ballast roadbed.
Fig. 1.1b is an example of a side view of a single concrete block for ballast roadbed.

Claims (3)

The present invention relates to a lifting / returning tool for a concrete block for ballast roadbed such as a railway track, and in the transportation and construction process, the two concrete blocks are simultaneously lifted and moved, and the angle is doubled, a rotating rod part installed above the angle, and A two-block simultaneous hanging tool that can be installed with a taper pin with a lock bar fixing groove installed at the bottom of the angle. The present invention relates to a lifting / returning device for a concrete block for a ballast road floor such as a railroad track. The taper pin with the lock bar fixing groove installed at the bottom of each angle is inserted and inserted into the drain hole that penetrates the lower part of each block vertical surface, and at the same time is connected and fixed with a pin drop prevention bar. Along with the angle part, the stable posture of the front and rear of the two blocks is considered. Claim 1 and Claim 2 Concerning the concrete two-block simultaneous lifting tool, each angle lower pin is provided with a cylindrical taper shape, a pin groove preventing lock bar fixing groove, and the two concrete block length direction pins. Has the effect of maintaining a horizontal posture.
