Description

[Detailed Description of the Invention] This invention relates to a single track device, and more particularly, to a single track device used for guiding the travel of a hand-pushed carrier.

In greenhouses such as greenhouses used for greenhouse cultivation, hand-held transport vehicles are used to transport the harvest inside, and these hand-held transport vehicles move along single tracks laid on the ground. I'm starting to be able to do it.

However, the single track installed inside the facility greenhouse is not permanently installed, and it is necessary to temporarily remove the single track in order to reverse the tillage of the internal field after each harvest, and it is easy to remove. Moreover, there is a need for something that is easy to install.

Therefore, this invention aims to meet the above-mentioned demands and provide a single track device that allows transport vehicles loaded with cargo to run safely.To this end, it is necessary to connect the unit tracks that make up the single track, The structure is characterized by easy disassembly and assembly because the pillars erected for the installation also serve as supports for the connected single track, and the construction allows the transport vehicle to run safely after the installation. It is something to do.

Next, the configuration of this invention will be explained with reference to embodiments shown in the attached drawings. First, in FIG. 1, reference numeral 10 designates the entire single track system, which is installed in any farm field such as a greenhouse, and a hand-held carrier can run along this single track system. This single track device is made by connecting unit tracks 1 of a certain length to a predetermined length. Each unit track 1 uses a square hollow pipe, and one end of the terminal track 1 is left open. An insertion space 1a is formed up to the end of the unit track 1, and a step piece 2, which is inserted and fixed into the internal space of the unit track 1, projects from the other end. This stepson 2
A hollow rectangular cross-section pipe is used which is fitted into the internal space of the unit track 1, with approximately half of the total length being fitted into the unit track 1 and the remaining half protruding. This stepper 2 has a through hole 2a that passes through it in the vertical direction, so that a post described later can be inserted thereinto.

Further, the insertion space 1a formed at one end of the unit track 1 is into which the step piece 2 can be inserted, and the end face of the unit track 1 is adapted to collide with the end face of an adjacent unit track 1 having the step piece 2. A through hole 1b whose center is coaxial with the through hole 2a is bored through the upper and lower surfaces of the unit track 1. One end of a support tube 3, which is a pipe cut to an appropriate length, is fixed to the through hole 1b on the lower surface of the unit track 1, and the support tube 3 is inserted through the through hole 1b through the internal space of the support tube 3. It is designed so that it can be inserted. A bolt hole 3a is bored in the side surface of the support tube 3.
A nut 3b for forming a threaded portion into which a tightening bolt 4 can be screwed is fixed to a.

Adjacent units of such unit tracks 1 are connected to each other, and the step piece 2 is inserted into the insertion space 1a at one end, and the support 5 is placed at the position where the through holes 1b and 2a are aligned. Inserted. One end of the strut 5 is formed with a flange 5a that is slightly larger than the diameter of the through hole 2a, and the other end is driven into a supporting surface such as a field, and the support tube 3 and the strut 5 are connected by screwing in a tightening bolt 4. is kept in a fixed state. The driving length of the strut 5 is determined in relation to the height above the ground and the supporting force of the strut 5.

Next, the procedure for installing the single track device according to this invention will be explained. First, insertion space 1 of unit orbit 1
Insert the step piece 2 of the adjacent unit track 1 into the hole a, insert the support 5 through the through holes 1b, 2a and the support pipe 3 from the top to the bottom of the unit track 1, and place the support 5 in the field. Type in and set up. By screwing in the tightening bolt 4, the strut 5 and the support tube 3 are integrated,
It is installed at an appropriate height above the ground.

As shown in the cross-sectional view of Fig. 4, the wheels of a hand-propelled carrier that travels on a single track system are driven by wheels W ₁ that ride on the top surface of the single track system and guide wheels W ₂ that contact both sides. . The wheel W ₁ has a small diameter at the center so that it is not affected by the upper end of the support column 5.

As is clear from the above explanation, the single track device of this invention has one end of the unit track as the insertion space,
A step piece that can be fitted into the insertion space of the unit track adjacent to the other end is fixed, a through hole is made in both so that the column can be inserted through the insertion space and the step piece, and the end of the column is inserted into this hole. The support pipe is fixed in a through hole that connects to the insertion space, and the end of the tightening bolt can protrude into the support pipe. Removal is also very easy.

Claims (1)

[Scope of utility model registration request] The mutually connected unit tracks have an insertion space at least at one end thereof, and a step piece at the other end that can be inserted into the insertion space of an adjacent unit track, and the insertion space and the step piece have a unit track and a step piece. It has a through hole that communicates between the two in a connected state, and the through hole at the bottom of the insertion space has a support tube with a tightening bolt for the support column, and the support tube is passed through the support tube from the through hole to connect the support column to the support surface. A single track device characterized by being configured so that the support tube's tightening bolt and the support column can be fixed by driving into the support tube.
