Abstract

(57) [Abstract] [Purpose] To extend the life of the scraper mounted on the trolley body and in sliding contact with the rail surface, and to save labor such as frequent replacement of the scraper. [Structure] The scraper 5 is supported by the carriage main body 1 in a freely descending state so that the lower end 5a of the scraper 5 is always in contact with the rail surface 2a by its own weight.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a carrier truck in which a scraper that is in sliding contact with a rail surface is mounted on a carriage body that is configured to travel and move along a rail.

[0002]

[Prior art]

 In a carrier truck that travels along rails laid in a factory where dust is likely to be generated, a scraper that removes dust is installed to prevent traveling due to dust accumulated on the rail surface and to protect the wheels. It is common to be. When attaching such a scraper, conventionally, as shown in FIG. 3, the scraper is mounted on a front portion of a carriage main body 33 configured to be movable along the rail 31 via wheels 32 transferred on the rail 31. The brush-shaped scraper 34 slidingly contacting the rail surface 31a or the cover-shaped scraper 35 made of a synthetic resin plate as shown in FIG. 4 is mounted in a fixed state.

[0003]

[Problems to be solved by the device]

 However, according to the conventional carrier truck as described above, since the brush-type scraper 34 or the cover-type scraper 35 is attached to the carriage main body 33 in a fixed position, the scrapers 34, 35 are attached. Since the lower end of the rail has a large sliding resistance between the rail surface 31a and the rail surface 31a, the rail surface 31a is likely to be worn or broken at an early stage, and the cleaning function for the rail surface 31a is lost at an early stage. For this reason, maintenance such as vertical position adjustment and replacement of the scrapers 34 and 35 must be frequently performed.

The present invention has been made to solve the above-mentioned conventional problems, and provides a carrier truck capable of exhibiting a good scraper function for a long period of time while achieving labor saving in maintenance. Is intended.

[0005]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the carrier truck according to the present invention is equipped with a scraper that slides on the rail surface and is attached to a truck body that is configured to be movable along the rail via wheels transferred on the rail. In the carrier truck, the scraper is supported by the carriage body in a freely descending state so that the lower end of the scraper always contacts the rail surface by its own weight.

[0006]

[Action]

 According to the transporting vehicle having the above-described configuration, the lower end of the scraper is always in contact with the rail surface due to its own weight, so that dust and the like on the rail surface are slidably contacted with and removed from the scraper along with traveling movement. Further, since the scraper is supported in a freely descending state with respect to the trolley body, wear of the scraper is reduced, and the rail surface cleaning function is maintained regardless of the degree of wear, so that the scraper is frequently used. It is possible to save labor for maintenance such as replacement.

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a side view showing a carrier truck according to an embodiment of the present invention. In the figure, reference numeral 1 is a bogie body, and a pair of vehicle wheels 3 and 3 transferred on a rail 2 are axially supported at an appropriate interval in the front and rear direction. It is configured so that it can travel along and move freely. Reference numerals 4 and 4 are support shafts of the wheels 3 and 3. Numerals 5 and 5 are scrapers arranged respectively in front of and behind the trolley body 1 and in sliding contact with the rail surface 2a, and are made of, for example, prismatic rubber. Reference numerals 6 and 6 denote scraper supporting members attached to the front and rear surfaces of the bogie main body 1, respectively, and are configured in a frame shape so as to embrace the scrapers 5 and 5, and the lower ends 5a of the scrapers 5 and 5, The scrapers 5 and 5 are supported in a free descending state with respect to the trolley body 1 so that the rail 5a constantly contacts the rail surface 2a by its own weight.

In the transport carriage having the above structure, the lower end 5a of the scraper 5 supported by the carriage main body 1 via the scraper support member 6 is always in contact with the rail surface 2a, and therefore moves along the rail 2. Accordingly, the lower end 5a of the scraper 5 comes into sliding contact with the rail surface 2a. Therefore, even if dust or the like is accumulated on the rail surface 2a, it is removed by the scraper 5 and the rail surface 2a is cleaned, so that stable transportation of the transport carriage is ensured.

Since the scraper 5 is supported by the trolley body 1 in a freely descending state and is not subjected to a mechanical forcing force on the rail surface 2a, the lower end 5a of the scraper 5 and the rail surface 2a are melted. The sliding resistance to and is relatively small, and therefore, the scraping function of the scraper 5 is reduced and the cleaning function for the rail surface 2a is kept good for a long time. Therefore, maintenance work such as frequent replacement of the scraper 5 can be omitted.

[0010]

[Effect of device]

 As described above, according to the present invention, since the scraper is supported by the trolley body in a freely descending state so that the lower end of the scraper is always in contact with the rail surface due to its own weight, wear of the scraper can be reduced and A good cleaning function of the scraper can be exerted for a long period of time. Therefore, it is possible to extend the maintenance cycle for exchanging the scraper, thereby achieving labor saving in maintenance.
