Abstract
The utility model discloses a single girder portal crane. The single girder portal crane comprises a main beam, wherein an electric block is mounted on the main beam, support legs are fixedly connected to two ends of the main beam and comprise a left support leg and a right support leg which are fixedly connected with the main beam, a ground beam is connected with the lower ends of the left support leg and the right support leg, driving and driven wheels are mounted at two ends of the ground beam and roll along a guide rail, a speed reducer is in transmission connection with the driving and driven wheels externally as well as an electric motor, and a brake is mounted on the transmission shaft between the speed reducer and the electric motor. The single girder portal crane has the advantages that the integral structure is firm, the weight is reduced, and the portal crane is convenient and rapid to use and can be stably driven at a high speed.
Description
Technical field
The utility model relates to hoisting crane field, specifically belongs to single girder gantry crane.
Background technology
Crane in bridge type be crossbearer in workshop, warehouse and overhead, the stock ground weight-lifting equipment that carries out material handling.Because its two ends are seated on tall and big concrete column or metallic support, shape is like bridge.The crane span structure of crane in bridge type longitudinally moves along being laid on the track of both sides on overhead, can make full use of the space handling material below crane span structure, is not subject to the obstruction of wayside equipment.It is a kind of elevator machinery that range of use is the widest, quantity is maximum.Existing LH type hoisting crane adopts steel-wire rope type electric block, often occurs the phenomenon of transmission bumpy motion.
Utility model content
The purpose of this utility model is to provide a kind of single girder gantry crane, and integral structure is firm, and weight saving is convenient to use, and fast speed underdrive is more steady.
The technical solution of the utility model is as follows:
Single girder gantry crane, include girder, electric block is installed on girder, and girder two ends are fixedly connected with supporting leg, and supporting leg includes and is fixedly connected with left branch leg, right supporting leg, between left branch leg and right supporting leg lower end, be connected with grade beam, grade beam two ends are provided with principal and subordinate wheel, and principal and subordinate wheel rolls along guide rail, and principal and subordinate wheel is connected with reductor outward, speed reducer drive is connected with electrical motor, on the transmission shaft between reductor and electrical motor, drg is installed.
Described drg, electrical motor are provided with protective cover outward.
Integral structure of the present utility model is firm, and weight saving is convenient to use, and fast speed underdrive is more steady.
