Problems solved by technology

There are some structural defects in the existing single-girder crane: for example, the main beam and the end beam are box-type structures welded together, and the use of materials is not reasonable enough, which is not conducive to reducing costs; The gap between the tracks affects the stability of operation; for another example, there are many intermediate steps when the anti-offside system of the cart, trolley and electric hoist stops. If there is a problem in a certain link, it will not be able to stop in time and cause a safety accident; etc.

Embodiment Construction

[0026] In order to better understand the technical principle and working process of the embodiments of the present invention, the present invention will be further described in detail below in conjunction with the drawings and specific embodiments.

[0027] see also Figure 1a-Figure 1c , shows the overall structure of the single beam crane of the present invention. Such as Figure 1a-Figure 1c In the single-girder crane shown (hereinafter referred to as the crane), the middle main beam 2 and the end beams 3 on both sides are fixedly connected to form a beam frame, and the end beam track 11b is fixed on the steel structure 1 of the factory building by the end beam track support 11a. Driven by the cart (including the active train set 12a and the passive train set 12b), it can run on the end beam track 11b, the electric hoist 7 runs on the main beam track with the trolley 4, and the crane is controlled by the remote control 5 to move in three directions , the hook 8 can easily...

Abstract

The invention discloses a single-beam overhead crane in one embodiment. The single-beam overhead crane comprises a beam frame, a cart, a trolley, an electric block and a control mechanism; an end beam is composed of end beams on the two sides and a main beam connected with the end beams; the end beams are driven by the cart to travel on an end beam track; the electric block runs on a main beam track along with the trolley; a guide wheel device is mounted on the frame of the cart or the trolley or on both the frames of the cart and the trolley to keep the cart and / or the trolley run stably; the control mechanism is provided with an anti-crossing system to shut down a motor in case of a crossing fault. According to the single-beam overhead crane, the overall single-beam overhead crane and the auxiliary system thereof are improved, and therefore, the performance of the product can be improved in the aspects of manufacturing cost reduction, steady operation guarantee, safety performance improvement and the like.

Description

technical field [0001] The invention relates to hoisting machinery, in particular to a single-girder crane and its sub-systems. Background technique [0002] Single girder crane is a kind of common lifting machinery, including beam frame, cart, trolley, electric hoist and control mechanism and other parts: the beam frame is composed of end beams on both sides and the main beam connecting the end beams, and the end beam is composed of carts The drive runs on the end beam track, and the electric hoist runs on the main beam track with the trolley, thereby lifting the workpiece at the corresponding position through the hook. There are some structural defects in the existing single-girder crane: for example, the main beam and the end beam are box-type structures welded together, and the use of materials is not reasonable enough, which is not conducive to reducing costs; The gap between the tracks affects the stability of operation; for another example, there are many intermediat...
