Abstract
The balance arm comprises an arm body, a lifting lug arranged in the middle of the arm body, a hook arranged at one end of the arm body and a balance weight arranged at the other end of the arm body, wherein an axial sliding groove is formed in the arm body at the counterweight end, a sliding block which slides axially is arranged in the axial sliding groove, and the balance weight is arranged at the bottom of the sliding block; an axial lead screw is arranged in the axial sliding groove, the inner end of the axial lead screw and the inner end of the axial sliding groove are rotatably arranged, and the axial lead screw is connected with the sliding block through threads and penetrates out of the axial sliding groove. Its adjustable counter weight is in the position of davit body, and then the moment of adjusting the counter weight, and both ends are balanced about messenger handling in-process davit body, and its reduction counter weight quantity that can be great reduces manufacturing cost, and the counter weight is adjusted simple structure, convenient operation, great reduction intensity of labour shortens the activity duration, improves handling efficiency.
Description
Technical Field
The utility model relates to a balanced davit is used at the harbour, especially relates to a balanced davit in harbour with adjustable counter weight.
Background
The balance suspension arm is a lifting hook which is hooked on a crane and is used for horizontally lifting the ton bags into the cabin through the cabin door. The balance suspension arm mainly comprises a suspension arm body, a lifting lug arranged in the middle of the suspension arm body, a hook arranged at one end of the suspension arm body and a balance weight arranged at the other end of the suspension arm body. The counter weight among the current balance davit passes through bolt and davit body fixed mounting, because the weight of ton bag varies, in order to handling in-process balance davit keep the horizontality, all need change the counter weight of corresponding weight before the handling ton bag at every turn, the counter weight is in large quantity, high in manufacturing cost, and it is high to change counter weight intensity of labour, and it is long to change counter weight operating time, and the handling is efficient.
Disclosure of Invention
The utility model relates to a solve above-mentioned technical problem, provide a harbour balance davit with adjustable counter weight, its adjustable counter weight is in the position of davit body, and then the moment of adjusting the counter weight, makes both ends balance about the handling in-process davit body, and its reduction counter weight quantity that can be great reduces manufacturing cost, and simple structure is adjusted to the counter weight, convenient operation, great reduction intensity of labour shortens the activity duration, improves handling efficiency.
The technical solution of the utility model is that:
harbour balance boom with adjustable counter weight, including the davit body, locate the lug at davit body middle part, locate the couple of davit body one end, locate the counter weight of the davit body other end, its special character lies in: an axial sliding groove is formed in the boom body at the counterweight end, an axially sliding block is arranged in the axial sliding groove, and the counterweight is installed at the bottom of the sliding block; an axial lead screw is arranged in the axial sliding groove, the inner end of the axial lead screw and the inner end of the axial sliding groove are rotatably arranged, and the axial lead screw is connected with the sliding block through threads and penetrates out of the axial sliding groove.
Further preferably, the two sides of the sliding block are respectively provided with a supporting wheel, so that the friction force between the sliding block and the axial sliding groove is reduced.
Further preferably, the axial lead screw and the inner end of the axial sliding groove are mounted through a bearing.
Further preferably, a rocker is installed at the end, penetrating through the axial sliding groove, of the axial lead screw, so that the axial lead screw can be conveniently rotated.
The utility model has the advantages that:
because locate the axial spout of davit body, the counter weight passes through slider and axial spout slidable mounting, sets up the inner rotation installation of axial lead screw in the axial spout and axial spout, and the axial lead screw passes through threaded connection with the slider. The axial adjusting slide block of the axial lead screw is rotated to enable the balance weight to be close to the middle part of the suspension arm body or far away from the middle part of the suspension arm body, and then the moment of the balance weight is adjusted to enable the left side and the right side of the suspension arm body to be balanced. The counter weight quantity is greatly reduced, the manufacturing cost is reduced, the counter weight adjusting structure is simple, the operation is convenient, the labor intensity is greatly reduced, the operation time is shortened, and the lifting efficiency is improved.

Detailed Description
As shown in fig. 1 and 2, the balance boom for a port with an adjustable balance weight comprises a boom body 1, a lifting lug 2 welded at the middle part of the boom body 1, a hook 3 welded at one end of the boom body 1, and a balance weight 4 installed at the other end of the boom body 1, wherein an axial sliding chute 5 is arranged at the end of the balance weight 4 on the boom body 1, a sliding block 6 sliding axially is arranged in the axial sliding chute 5, supporting wheels 7 supported at the bottom surface of the axial sliding chute 5 are respectively installed at two sides of the sliding block 6, and the balance weight 4 is installed at the bottom of the sliding; an axial lead screw 8 is arranged in the axial sliding groove 5, the inner end of the axial lead screw 8 and the inner end of the axial sliding groove 5 are installed through a bearing, the axial lead screw 8 and the sliding block 6 are connected through threads and penetrate out of the axial sliding groove 5, and a rocker 9 is installed at the end, penetrating out of the axial sliding groove 5, of the axial lead screw 8.
During operation, firstly, a lifting hook of a crane is hooked on the lifting lug 2, then the ton bag is hooked on the hook 3, then the axial lead screw 8 is rotated to axially adjust the sliding block 6, so that the balance weight 4 is close to the middle part of the suspension arm body or far away from the middle part of the suspension arm body, the moment of the balance weight 4 is adjusted, the left side and the right side of the suspension arm body are balanced, and finally, the ton bag is horizontally conveyed into a cabin through a cabin door by hoisting the crane.
The above description is only an example of the present invention, and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
