Embodiment Construction

[0033] Preferred embodiments of the invention are described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principles of the invention, and are not intended to limit the protection scope of the invention.

[0034] It should be noted that, in the description of the invention, terms such as "upper", "lower", "left", "right", "inner", "outer" and other indicated directions or positional relationships are based on the terms shown in the accompanying drawings. Orientation or positional relationship, which is only for convenience of description, and does not indicate or imply that the device or element must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation on the invention.

[0035] In addition, it should be noted that, in the description of the invention, unless otherwise clearly stipulated an...

Abstract

The invention provides a special pulley construction device and a special pulley construction method for a cable duct. The special pulley construction device comprises a vertical bracket arranged on aside wall, the lower part of the side wall is filled with concrete, a supporting part is arranged on the upper part of the side wall, and a crossed rod group is arranged above the vertical bracket. When the device is used for construction of the cable duct at a certain height, a material needs to be placed in the cable duct. When the material at a low height is released, a steel wire rope is suspended through a pulley to release the material at the lower end, so that the material can be placed to an appointed position precisely. In a construction process, if the material needs to be releasedat a high height, a vertical oil cylinder jacks a pulley bracket upward, so that the pulley bracket is lifted to a proper preset height, the material and the release position are properly separated, the material is released in position precisely, and the material released at the high height is prevented from being scattered.

Description

technical field [0001] The invention relates to the technical field of cable trenches, in particular to a special pulley construction device and construction method for cable trenches. Background technique [0002] At present, the traditional highway tunnel cable trench is generally composed of a cable trench bottom plate, a side wall and a cover plate. [0003] During the masonry process of the cable trench, heavy objects or materials need to be transported by pulleys. For example, in the process of civil engineering construction, such as trench bottom leveling, cement mortar or crushed stone concrete leveling, etc., walls of different heights and positions need to be body for construction. [0004] However, the pulleys in the prior art are generally arranged on the wall brackets, and when different side walls are being constructed, the pulleys need to be disassembled frequently, resulting in prolonged construction period and inconvenient use.
