In addition, the ends of the clamp are connected to one of the flanges of the I-beams, which are located in parallel planes perpendicular to the plane of the clamp under the conditions: h = d ;;;, where h ,, b, respectively height, rack width, shelf width, I-beam thickness capture; L, B, d – length, link width, chain gauge, respectively. 3 ill.

Description

The invention relates to devices for connecting flexible elements and can be used in the formation of rafts from round timber.

A device for connecting intersecting rope and chain containing hooks interconnected by a jumper (Patent RU 67971 IPC B 65 G 69/20. 2007). The disadvantage of this device is the lack of reliability of the connection.

Closest to the claimed solution is the lock TsLS-88, consisting of a collar with a jumper and bent threaded ends, strips with holes for the ends of the clamp and two nuts (Forest exploitation and timber rafting. Express information. Domestic production experience, issue 20, M. 1987, p. 22-23). This castle is taken as a prototype. The prototype has a disadvantage - significant labor costs when setting up a castle.

The problem, the solution to which the utility model is directed, is to reduce labor costs when setting up the device.

The clamp of the device interacts with the cable 3 of the on-board bench lying on the horizontally located link 4 of the chain of the on-board kit, and the I-arms capture with vertically arranged adjacent links of the chain 5. At the same time, horizontally located segments of these links in the working position are located between the flanges of I-grips under the following conditions: h = d;

, причем расположенное справа – против часовой стрелки, а рсположенное слева – по часовой стрелке. Устройство сдвигают вдоль каната 3 до контакта хомута 1 с этими звеньями 5 цепи. Звенья 5 цепи возвращают в исходное положение, при этом горизонтально расположенные отрезки вертикально раположенных звеньев 5 располагаются между полками 2 двутавровых захватов. После этого бортовой комплект утягивают. В результате обеспечивается соединение перекрещивающихся каната и цепи.The device is used as follows. On the rope 3, lying on a horizontally located link 4 chains impose a clamp 1 of the device, and adjacent vertically located links 5, rotate in a vertical plane at an angle

, and located on the right - counterclockwise, and located on the left - clockwise. The device is shifted along the rope 3 to the contact of the clamp 1 with these links 5 of the chain. The links 5 of the chain are returned to their original position, while horizontally located segments of vertically arranged links 5 are located between the shelves 2 of the I-beam grips. After that, the on-board kit is pulled off. The result is a connection of the crossing rope and chain.

The proposed device allows to reduce labor costs when moving the device.
