Description

The present invention provides a hose moving device that can easily move a large diameter hose such as a concrete pumping hose used when pumping and placing concrete at a construction site, a bottom member of the hose moving device, The present invention relates to a method of manufacturing a bottom part of a hose moving device and a method of manufacturing a bottom member of a hose moving device.

When pouring concrete using a concrete pressure hose at a construction site, a worker supports the tip of the pressure hose and pours the concrete into a predetermined location. When changing the placement location, the tip of the pressure hose must be moved, but because the pressure hose is heavy, it is not easy to lift and move it, and it is difficult to move it while dragging it over reinforcing bars. becomes. However, the pressure hose is heavy, so if it is dragged while being moved, the hose body may wear out prematurely or cracks may occur in the hose body. In addition, when moving on reinforcing bars, the reinforcing bars may be pulled and deformed by the pressure feeding hose, and in some cases, there is a risk that the binding wires of the reinforcing bars may be cut. Therefore, as shown in Patent Document 1, for example, a hose moving device has been developed that can smoothly move a heavy concrete pressure-feeding hose without dragging it and has a simple structure. This hose moving device is an integrally molded box made of resin, more specifically reinforced plastic, and has support recesses formed at the upper ends of the front and rear sides to accommodate and support the hose. The box is placed on reinforcing bars and the hose is inserted into the support recess of the box. If you try to move the hose by pulling it, for example, you can slide the box on the reinforcing bars and move the hose smoothly.

However, since concrete pressure hoses are heavy and often need to be moved frequently at the pouring site, the sliding surface of the bottom of the box of the hose moving device is subject to severe wear. However, the problem is that it has a short lifespan.

Therefore, a hose moving device has also been developed in which a thin plate material with excellent abrasion resistance is embedded in the bottom to prevent early wear and tear of the bottom (for example, see Patent Document 2 and Patent Document 3).

Although the hose moving devices described in Patent Document 2 and Patent Document 3 have excellent durability, they have a structure in which a wear-resistant plate is embedded entirely in the bottom, which increases the weight too much and increases the price. In order to prevent the wear resistance from becoming too high, it may be necessary to use a wear-resistant plate as thin as possible, and it is not always possible to ensure sufficient wear resistance.

SUMMARY OF THE INVENTION Therefore, the present invention aims to provide a new hose moving device with a long life, a new bottom member with a long life of a hose moving device, and a new method of manufacturing a bottom part or bottom member with a long life of a hose moving device. do.

To achieve this object, the hose moving device of the present invention is provided with supporting parts that support the hose at the front and rear sides, for example, at the upper end or on the upper side, and for example, the lower surface of the bottom made of resin has a sliding surface. A box-like or low-height box-like hose moving device, the bottom of which is recessed downward and whose lower surface forms the slide surface and which is elongated in the front-rear direction or extends in the front-rear direction. A plurality of extending accommodating recesses are formed, and a slide member that is exposed when the bottom surface of the accommodating recess is worn away is housed and fixed in the accommodating recess. Since the lower surface of the housing recess forms a sliding surface, the bottom surface of the housing recess will wear out as the hose moving device is used for a long time. When the bottom surface of the receiving recess is worn out, the slide material contained therein is exposed, and the hose moving device can be used continuously until the slide material is significantly worn. Moreover, since an elongated storage recess is formed at the bottom of the hose moving device, and a long and thin slide material is housed in this storage recess, the weight of the hose moving device increases when adopting a structure that extends the life of the hose moving device. A structure is adopted that reduces the amount of slide material used. The number of accommodation recesses can be two, three, or four, and the number of accommodation recesses is such that the total width of the entrance of the accommodation recess is about half the width of the bottom of the hose moving device, or the number of accommodation recesses is can be configured such that the sum of the widths of the inlets is greater than one-half the width of the bottom of the hose transfer device.

It can be constructed as one in which the slide material is housed and fixed.

As the slide material, a material made of, for example, hard resin having excellent wear resistance can be used. However, by forming the housing recess deeply and making the slide material that is housed in the housing recess thick, it is possible to slide the hose moving device without using a hard resin material with excellent wear resistance. It can effectively extend the life of the surface. Therefore, it is possible to use a material with a small coefficient of friction and excellent sliding properties as the material of the sliding member, so that the frictional force acting on the sliding object such as the reinforcing bar can be reduced. That is, the entire hose moving device is molded using, for example, general fiber-reinforced plastic, specifically glass fiber-reinforced plastic, glass fiber-reinforced polyester resin, or epoxy resin, but the slide material is made of such fiber-reinforced plastic. For example, it may be made of resin, which has a smaller coefficient of friction than plastic, and may also be made of HDPE (high density polyethylene). Alternatively, the slide material can be made of metal, such as stainless steel or steel, which is more durable than resin. Moreover, instead of arranging the slide material formed in advance in the accommodation recess, resin putty, which is a material for the slide material, may be supplied to the accommodation recess, and this putty may be cured to be used as the slide material.
