Embodiment Construction

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

[0023] image 3 It is a schematic diagram of the structure of a jacket type pulley block direction changing balance system of the present invention. Such as image 3 , Figure 4 As shown, a jacketed pulley block direction changing balance system includes a cage 13, a counterweight 16, a jacket pulley guide frame 10, and a unidirectional ratchet 9 forming a unidirectional ratchet assembly. The outer pulley guide frame 10 has a rectangular truss structure, which is installed and sleeved outside the standard section 14 and can move up and down along the standard section 14 track. The unidirectional ratchet assembly mounted on the back of the outer pulley guide frame 10 meshes with the vertical rack 15 of the standard section 14 to form a unidirectional ratchet system. Two symmetrical guide pulleys I and VIII are installed on the bottom of the front 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 during building construction, and specifically relates to a jacket type pulley block direction-changing balance weight system during construction. Background technique [0002] In engineering construction, with the gradual popularization of mechanization, construction elevators also occupy an irreplaceable position in this field. The construction hoist is a kind of construction machinery that is often used in the process of building construction. It is mainly used for the construction of high-rise buildings, bridges, chimneys and other buildings. [0003] General construction elevators include hanging cages, standard sections, drive mechanisms, electrical systems and counterweight systems, etc. We all lift building materials from low to high in the construction process. In the process of this movement, the dead weight of the cage and the transmission mechanism is the load, which is doing useless work. T...
