Embodiment Construction

[0022] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0023] image 3 It is a structural schematic diagram of a direction-changing balance system of an outer sheath pulley block of the present invention. Such as image 3 , Figure 4 As shown, an outer pulley block direction changing balance system includes a cage 13, a counterweight 16, an outer pulley guide frame 10, and a one-way ratchet assembly formed by a one-way ratchet 9. The outer sheave guide frame 10 is a rectangular truss structure, installed outside the standard joint 14, and can move up and down along the standard joint 14 track. The one-way ratchet assembly installed on the back of the outer sheave guide frame 10 meshes with the vertical rack 15 of the standard section 14 to form a one-way ratchet system. Two symmetrical guide pulleys I, guide pulley VIII are equipped with respectively at the front bottom of described o...

Abstract

The invention discloses an external pulley set type reversing balancing counterweight system. The external pulley set type reversing balancing counterweight system comprises a lifting cage, a counterweight, an external pulley guide frame and an one-way ratchet wheel, wherein the external pulley guide frame is of a rectangular truss type structure which sleeves the outer part of a standard section; the one-way ratchet wheel assembly is engaged with a vertical rack of the standard section to form an one-way ratchet wheel system; a guide pulley I and a guide pulley VIII are correspondingly mounted at the front bottom parts of the left side surface and the right side surface of the external pulley guide frame; a guide pulley II and a guide pulley VII are correspondingly mounted on the top parts of the left side surface and the right side surface of the external pulley guide frame; a reversing guide wheel III, a reversing guide wheel VI, a guide pulley IV and a guide pulley V are mounted on the front surface of the external pulley guide frame; the counterweight is connected with the lifting cage through steel wire ropes on the guide pulleys. According to the external pulley set type reversing balancing counterweight system, the top end of the standard section is empty, so that the steel wire ropes and a tower top reversing system cannot be dismounted during heightening the standard section of an elevator, and as a result, the safety of the jacking heightening work is improved, and the operation is simple and convenient.

Description

technical field [0001] The invention belongs to the technical field of lifting in the building construction process, and in particular relates to a jacket type pulley block direction changing balance counterweight system in the construction process. Background technique [0002] In engineering construction, with the gradual popularization of mechanization, construction elevators also occupy an irreplaceable position in this field. Construction hoist is a kind of construction machinery often used in the construction process, mainly used in the construction of high-rise buildings, bridges, chimneys and other buildings. [0003] General construction elevators include cages, standard sections, drive mechanisms, electrical systems and counterweight systems, etc. We lift building materials from low places to high places during construction. During this movement, the self-weight of the cage and the transmission mechanism is the load, which is doing useless work. How to eliminate t...
