(54)ЗАХВАТ-КАНТОВАТЕЛЬ(54) CAPTURE CHANGER

Изобретение относитс к грузозахватным; устройствамThe invention relates to lifting; devices

Известен захват-кантователь, содержащий несущую раму и установленный на ней механизм кантовани , содержащий звездочки с перекинутыми через них бесконечными цеп ми I. Однако отсутствие механизма осевого перемещени звездочек не позвол ет производить захват грузов различных размеров.A gripper-tilter is known that contains a supporting frame and a tilting mechanism installed on it, containing sprockets with endless chains I thrown over them. However, the absence of an axial movement mechanism for the sprockets does not allow for the capture of loads of various sizes.

Наиболее близким к изобретению вл етс захват-кантователь, содержащий несущую раму, установленный на ней механизм кантовани , включающий в себ привод, св занный с ним шестеренчатой передачей вал и установленные на валу звездочки, огибаемые бесконечными цеп ми, и механизм осевого перемещени звездочек 2. Однако необходимость в специальном приводе осевого перемещени звездочек усложн ет конструкцию устройства.Closest to the invention is a tilting device comprising a carrier frame, a tilting mechanism mounted on it, including a drive, a shaft connected with it by a gear transmission, and sprockets mounted on the shaft, bending around endless chains, and a sprocket 2 axially moving mechanism. However, the need for a special drive for the axial movement of the sprockets complicates the design of the device.

Цель изобретени - упрощение конструкции захвата-кантовател .The purpose of the invention is to simplify the design of the gripper.

Это достигаетс тем, что в предлагаемом устройстве механизм осевого перемен1,ени звездочек содержит установленные на валу гайки с разносторонней резьбой, наход щиес в резьбовом соединении со звездочками, а на раме закреплены электромагнитные тормоза , взаимодействующие с гайками.This is achieved by the fact that, in the proposed device, the mechanism of the axial variable1, the asterisk contains mounted on the shaft nuts with a versatile thread, which are in a threaded connection with asterisks, and electromagnetic brakes that interact with the nuts are attached to the frame.

На чертеже показано предлагаемое устройство , общий вид.The drawing shows the proposed device, the overall appearance.

Захват-кантователь содержит раму (показана , условно), привод 2, 3 с направл ющими шпонками 4 и жестко насаженной на него шестерней 5, механизм вращени и механизм осевого перемещени . Детали каждого механизма расположены на валу 3 симметрично относительно шестерни 5.The gripper-turning device contains a frame (shown, conventionally), an actuator 2, 3 with guide pins 4 and a gear 5 rigidly mounted on it, a rotation mechanism and an axial movement mechanism. Details of each mechanism are located on the shaft 3 symmetrically with respect to gear 5.

Механизм вращени включает звездочки 6 и бесконечные цепи / Звездочки б насажены на вал 3 и имеют возможность перемещатьс вдоль него по направл ющим шпонкам 4. На. ступицах звездочек б имеетс внешн резьба (на одной лева , на другой права ).The rotation mechanism includes sprockets 6 and endless chains / Sprockets b mounted on shaft 3 and have the ability to move along it along guide keys 4. On. The hubs of the sprockets b have an external thread (on one left, on the other right).

Claims

The axial movement mechanism contains nuts 8 with an internal thread (on one left, on the other right) and electromagnetic brakes 9 acting on the nuts 8. The nuts 8 are placed in frame 1 and are in threaded connection with sprockets 6. Endless chains 7 interact with with a load of 10 .. The tilter works as follows. In the initial state (before seizing the load 10), the sprockets were screwed into the nuts 8. The nuts 8 were braked by the brakes 9, the drive 2 was turned off. When the load 10 is gripped, the chain 7 is separated from the middle of the shaft 3. At the same time, the actuator 2 turns on and rotates the shaft 3 through the brush 5. The sprockets 6 rotate together with the shaft 3. As the nuts 8 are braked, the sprockets 6 are unscrewed from the nuts 8 and move them together with chains 7 on shaft 3 along guide keys 4 to the trunnions of the load 10. The load 10 is gripped by each endless chain 7. When turning the load 10, the nuts 8 are disengaged 8. The shaft 3 rotates, the sprockets 6, the nuts 8 and the chains 7 rotate with it Canting load 10 to the desired position occurs. When releasing the load 10, the nuts 8 are braked by means of the brakes 9, the rotation from the actuator 2 is transmitted to the sprockets 6. The sprockets 6 are unscrewed from the nuts 8 and the chain 7 is retracted from the load axles 10. The load is released. The combination of the rotation mechanism and the axial mechanism movement in one node allows you to simplify the design of the turner, eliminating from it one gear motor and other parts of the axial movement mechanism, thereby reducing the size and weight of the turner. Claim capturing device, comprising a carrier frame, a canting mechanism mounted on it, including an actuator, a shaft connected to it with a gear and sprockets mounted on the shaft, endless chains, and an axial movement mechanism of sprockets, characterized in that In order to simplify the design of the gripper-turner, the mechanism for the axial movement of the sprockets contains nuts with versatile threads mounted on the shaft, which are in a threaded joint with sprockets, and Electromagnetic brakes, interacting with the nuts.
