Detailed Description
In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand and understand, the present invention is further explained by combining with the specific drawings.
This example is great to the driving among the current bridge crane, influences the problem of hoist and mount scope in narrow and small space, provides one kind for the design of bridge type, gantry crane's play to rise hoist load dolly.
The scheme of the load-carrying trolley adopts a duplex multilayer winding drum and is matched with a built-in reduction gearbox and a guide pulley to form, so that the size of the load-carrying trolley can be effectively reduced.
Referring to fig. 1 and fig. 2, a schematic structural diagram of the small-gauge hoisting winch truck in the present embodiment is shown.
As can be seen from the figure, the hoisting and hoisting load-carrying trolley is formed by mutually matching a motor 1, a trolley frame 2, a coupling 3, a brake 4, a supporting seat 5, an embedded reduction gearbox 6, a duplex multi-layer winding drum 7, a bearing seat 8, a guide pulley assembly 9, a steel wire rope 10, a lifting hook 11 and a steel wire rope fixing device 12.
Wherein, dolly frame 2 is the basis of whole scheme, can move in the track, and all parts are all installed on dolly frame 2. The specific configuration of the trolley frame 2 can be determined according to actual requirements, and is not described herein.
The duplex multilayer winding drum 7 is matched with the built-in reduction box 6 and is integrally supported on the trolley frame 2 through the matching of the bearing seat 8 and the supporting seat 5.
The brake 4 is directly mounted on the trolley frame 2 in cooperation with the motor 1. The motor 1 is used as a power source of the whole device, is in driving connection with the duplex multilayer winding drum 7 sequentially through the coupling 3 and the built-in reduction gearbox 6, and then drives the duplex multilayer winding drum 7 to rotate in the bearing seat 8.
The guide pulley assembly 9 is arranged relative to the duplex multilayer winding drum 7 and used for guiding the steel wire rope 10 and ensuring the running reliability.
In order to match the duplex multilayer winding drum 7, the guide pulley assembly 9 is formed by matching two guide sliding sets, the two guide sliding sets are arranged in parallel corresponding to the duplex multilayer winding drum, each guide sliding set is formed by matching two guide sliding sets, and the two guide sliding sets are arranged in a vertically staggered mode.
The steel wire rope fixing device 12 is arranged on the trolley frame 2 relative to the duplex multi-layer winding drum 7 and is used for connecting the steel wire rope 10. The specific configuration of the wire rope fixing device 12 can be determined according to actual requirements, and will not be described herein.
The steel wire rope 10 in the scheme is used as a transmission assembly, one end of the steel wire rope is wound on the duplex multilayer winding drum 7, the other end of the steel wire rope passes through the guide pulley 9 and then bypasses the lifting hook 11, and then the steel wire rope is connected to the steel wire rope fixing device 12, so that the lifting hook 11 is driven to move up and down through the rotation of the duplex multilayer winding drum 7.
For the structure of the duplex multilayer winding drum 7, two steel wire ropes 10 are adopted in the scheme, the two steel wire ropes 10 are correspondingly wound on the duplex multilayer winding drum 7, and rope ends of the two steel wire ropes 10 pass through two guide pulley blocks 9 from two sections of winding sections of the duplex multilayer winding drum 7 respectively, then pass through two pulleys of a lifting hook 11, and finally are connected to a steel wire rope fixing device 12. Therefore, the lifting hook 11 can be well driven to move up and down, the lifting height is high, the disorder of the multilayer winding drums can be avoided, and the running reliability of the whole device is guaranteed.
The embodiment scheme adopts the built-in reduction box to save more space; and the device is matched with a duplex multilayer winding drum, so that the track gauge size and the wheel track size are effectively reduced, and the hoisting range of the traveling crane in the whole operation process is enlarged.
Meanwhile, the guide pulley is adopted, so that the problem of rope disorder when the duplex multilayer winding drum is used for carrying out multilayer winding is solved, and the swinging of the steel wire rope in the winding process of the drum due to the swinging of the lifting hook is avoided, so that the rope disorder is avoided.
