Abstract

FIELD OF THE INVENTION The invention relates to lifting and transport machinery, and, in particular, to lifting devices. The purpose of the invention is to increase the safety of the device by providing automatic automatic signaling of the end of the test mounting loops. The device comprises a body with hook lines installed on it through two shoulders, and also the 20 Id device for testing the load mounting loops, which includes upper and lower hydraulic cylinders. An additional hydraulic cylinder 19 with a piston 20 and a rod 21 connected to the piston 12 of the ppev-cylinder mounted coaxially with the hydraulic cylinder 19 is fixed on the upper cylinder of the hydraulic cylinder. In the piston 12 there is a radial channel 13, which interacts with the holes 16 and 17 in the cylinder 9 and is connected to an acoustic emitter 14, fixed on the piston 12. The cavity of the hydraulic cylinder 19 is connected to the cavity of the upper power cylinder. When the device is raised, a preliminary testing of the strength of the spindle is performed, as a result of which the liquid from the power cylinder enters the additional hydraulic cylinder 19, moving the pistons 20 and 12 to the extreme right position. At the end of the loop test, the piston 12 is moved to the left by the action of the spring 11, compressing the air in the piston. When the channel 13 is connected to the hole 17, the compressed air enters the acoustic emitter 14, which signals the end of the test. This increases the safety of the device. 2 Il.

Description

i The invention from (Osit to the lifting and transport engineering, namely to the load gripping devices, is an improvement of the device but auth. St. NO 1119964.

The purpose of the invention is to increase the safety of the device by providing an automatic signal about the termination of assembly tests1) 1.x loops. FIG. I shows an intrinsic device, bs, i; in fig. 2 is a section A-A in FIG. one.

The catching device, which is hung on the k | backpack 1 of the lifting mechanism, contains strony 2 with hooks 3 for stroping g) of the narrow-lifting devices of the mounting loops 4 of the product 5. On the case 6 of the device, the upper 7 and vertically are installed 8 hydraulic cylinders. On the top g of the cylinder 7, the body of the pneumatic tube is installed: TdqecKoro of the cylinder 9, fixed by means of the clip 10. In the cylinder 9 there is a spring loaded with a spring 11 nopnjeHb 12 С; A radial m channel iK connected in it iK is connected to the radiator 14 attached to the iiopHine 1 acoustic. m.

In the right side of the cylinder body 9, a hole 15 is filled to connect the cylinder bore to the atmosphere. On the left side of the housing there are two openings 16 and 17, interconnected outside each other by a tensioner 18. On the housing of the pne.op.opillar 9, a hydraulic dial 19 with a piston 20 is fixed coaxially with it, the piston rod 2 of which is connected to the piston .m 12. Bestikotekovaya cavity of the cylinder 19 is connected by pipeline 2 with the rod cavity of the upper hydraulic cylinder 1 7 7.

On the case of the hydraulic cylinder 7, two shoulders levers 23 are pivotally mounted, one body of each of which 6 is connected to the line 2, and the other is equipped with a brake shoe 24.

The device works as follows.

Hooks 3 lines 2 captures from item 5 for the assembly there. 4. In raising the device, the slings 2 are tensioned, and the levers 23 by shoes 24 clamp the hydraulic cylinder body 8. The liquid of the hydraulic cylinder 7 under the weight of the product 5 enters the

rodless cavity of hydraulic cylinder 8 (testing of mounting loops begins). At the same time, the liquid enters the rodless cavity of the hydraulic cylinder 19, its piston 20 withdraws and the piston 12 connected with it by the rod 21 to the right. In this way the spring And compresses, and a vacuum is formed in the rod end of the cylinder 9. At the extreme right position of the piston 12, the rod cavity of the cylinder d is connected through the opening 15 to the atmosphere. After a continuous flow of fluid from cylinder 7, the test of the mounting loops ends. The piston 12 returns to its initial position under the action of springs 11, compressing the air in the piston cavity of the cylinder 9. In the extreme left position, the radial channel 13 of the piston 12 is connected to the cylinder bore 17, resulting in compressed air from the cavity of the cylinder 9 through the hole 16, the pipe 18, the hole 17 and the channel 13 enters the acoustic of the transmitter 14. which signals the end of the loop test. The product is lifted and carried to the installation site.

The invention makes it possible to accurately determine the end of the test of the mounting loops, which increases the safety of the operation of the device.
