(54) CAPTIVE DEVICE FOR STRING PRODUCTS WITH INTERNAL CAVITIES

I

The invention relates to lifting devices for carrying out lifting and transporting and mounting operations with building products, for example with hollow-core panels.

Lifting, transporting and assembling building products are carried out with various devices and grippers having a different constructional content.

 A gripping device for products with an internal cavity, containing a pull with a pick-up element at one end and an eye for hanging to a lifting device and a locking device for the working position of the pick-up element 1 j, is known.

However, such an implementation of the ke latch ensures complete reliability of the engagement, since there is no fixation of the feeder in the slotted opening, which does not preclude the release of the detent from the slot in the process, which makes it difficult to extract the gripper from the slot due to the slot. holes; requires a lot of effort for

 fitting into the slotted hole so

As an installation, the hooking of the slinging ropes is maintained while maintaining the grip and at the same time pressing the unbalance bar, and does not ensure a stable position of the grip in the hollow plane.

The aim of the invention is to increase reliability, convenience and safety in operation.

This goal is achieved by the fact that the lifting element and the tractor are made with vertical holes in which, respectively, a spring-loaded stop and a safety finger are located, interacting with a clamp made in the form of a plate 1Y.

FIG. Figure 1 shows a gripping device for products with an internal cavity, about (5 is the general view; Fig. 2 is a gripping device, side view, section A-A in Fig. 1; Fig. 3 is a gripping device prepared for a 90 ° turn for extraction from the void cavity of the product.

The gripping device comprises tgu 1 20 of FIG. I), at one end of which the pickup elements 2 are made, the supporting face of which repeats the surface profile of the internal cavity of the product 3, and at the other end of the pull rod 1, an eyelet 4 is made for suspending the device on the hook 5 of the lifting mechanism. The axis b is rigidly fixed to ti I (Fig. 2), the second plate, which fixes the working position of the gripping device, is hinged on the second plane in the plane perpendicular to the plane of the supporting face of the pickup elements 2. Under the pick-up elements 2, the stop 8 is installed, which is spring-loaded by the spring 9 and passes freely through the hole 10 in tons so that its upper end has the ability to come into contact with the plate 7. Above the plate 7 in t he 1 there is a hole 1 through which the movable safety finger 12, which is freely supported by the lower end, passes on the plate 7, and its upper end has the ability to exit into the hole 13 of the eyelet 4. The spring 9 is installed in a sleeve 14 rigidly fixed to the pickup elements 2. In the product 3 is made a slot 15. The gripping device operates as follows. The pick-up device is inserted into the slot 5 of the product 3 until the abutment of the support 8 into the bottom of the hollow channel of the product. 3. When pressed, it together with the plate 7 fixed on it moves along the support stop 8, compressing the spring 9. The plate 7, resting on the edge of the slot 5, HfspoBonted on axis 6, is retracted upwards. At the same time, with its upper edge, it moves the movable safety finger 12 upwards, which closes the opening 13 of the lugs 4 and thereby prevents the lifting mechanism 5 from being inserted into the opening 13 before the device is installed in the working position, ensuring safe operation. Turn the gripping device on the support stop 8 in the slot 5 to 90 °. When the plate 7 is aligned with the slot 15, it is. under the action of its own weight enters the slotted hole 15, thereby fixing the gripping device, and the movable safety finger 12 is lowered, OTHERWISE the hole 13 of the lugs 4 To insert the hook 5 of the lifting mechanism into it. The tension 1 is released, and under the influence of the spring 9, the support faces of the pick-up elements 2 abut against the surface of the void cavity of the product 3 and this stabilizes the position of the installed gripping device. In the hole 13 of the eyelets 4 plant t hook 5 of the lifting mechanism. When hook 5 of a load-lifting mechanism is inserted into hole 13 of hole 4, upward movement of movable safety pin 12 is prevented and, thus, spontaneous exit of plate 7 from slotted hole 15 is prevented, i.e. plate 7 is fixed in slot hole 15 and this ensures reliable product grip 3 and safe operation. In order to free the product 3 from the gripping device, the eyelets 4 of the hook 5 of the load-lifting mechanism are removed from the hole 13, they press on the rod 1, which together with the plate 7 moves down the stop 8. In this case, the upper end of the stop 8 turns the plate 7 on the axis 6 and withdraws from the slot hole 15 (Fig. 3). The gripping device is rotated 90 ° and removed through a slot-hole 15. The annual economic effect as a result of the implementation of the proposed gripping device in the enterprises of the production association is 20 thousand rubles. Claims of the Invention Pickup device for building products with internal nOviocTHMH, comprising a pull with a pickup element at one end and an eye for hanging to a weight lifting machine and a working position lock of the pickup element hingedly attached to the tractor, different in that reliability, convenience and safety in operation, the lifting element and the tractor are made with vertical holes in which, respectively, there is a spring-loaded stop and a safety pin interacting with iksatorom formed as a plate. .
