[0002] The calendered cord plays a role of skeleton support in the whole all-steel tire and is one of the most important components in the whole tire manufacturing process. The equipment for producing its products is a calender. When the thickness measuring device was modified to add a thickness measuring device, it was found that it interfered with the crane of the original hoisting groove roller. The space is relatively narrow, and the traditional hoisting mechanism is difficult to meet the actual hoisting needs. Therefore, in view of the above problems, a multi-axis universal lifting and hoisting device suitable for space constraints is designed to better meet the actual use needs. Utility Model Content

[0005] Preferably, a first brake disc is also fixed on the first rotating arm, and the first brake disc cooperates with the first brake damper to achieve a positioning effect. Through the action of the first brake disc and the first brake damper, the fixing and unlocking effects of the first rotating arm can be achieved.

[0006] Preferably, a limiting plate is fixed symmetrically front and back on the lower end surface of the first rotating arm, and the limiting plate contacts the fixing frame to achieve a limiting effect. Through the action of the limiting plate, the rotation angle of the first rotating arm can be limited to avoid collision and damage to the device.

[0007] Preferably, a second brake damper is also installed on the second rotating arm, and the second brake damper cooperates with the second brake disc to achieve a locking effect. Through the action of the second brake damper and the second brake disc, the second rotating arm can be locked to ensure the stability of the second rotating arm.

[0008] Preferably, a guide wheel is also connected to the second rotating arm by a bearing, and the guide wheel contacts the wire rope between the second hook and the electric hoist to achieve a guiding effect. Through the action of the guide wheel, the guiding effect of the wire rope can be achieved to avoid friction between the wire rope and the second rotating arm.

[0009] Preferably, a traction rope is fixed to the lower end of the electric hoist, and a controller is fixed to the lower end of the traction rope, and the controller is electrically connected to the electric hoist, the first brake damper and the second brake damper. The traction rope can be used to conveniently adjust and control the angle of the device to meet actual operating requirements. The controller can be used in conjunction with the device to realize the regulation function, providing a basic guarantee for the lifting of objects.

[0010] Compared with the prior art, the beneficial effects of the utility model are as follows: the multi-axis universal lifting and hoisting device suitable for space constraints can realize a smaller range of lifting and steering through a two-axis rotating arm structure, and at the same time, the lifting drive mechanism is rearwardly placed to reduce the lifting space occupied by the front-end actuator, thereby meeting the purpose of material transfer in a narrow space.
