Description

one

The invention relates to lifting means.

Devices for lifting and moving goods are known, comprising a horizontal support frame on wheels, "of which a fixed lifting boom with deflection rollers is attached, and manual winches.

The purpose of the invention is to increase the effect, performance of work and convenience of operation.

For this, the proposed device is equipped with an extendable roller table, made in Hades of sections with studs, connected between cf - power fight with alternating oblong and cylindrical openings mounted on trunnions with freely rotating lower limbs moving along direction points. , mounted on the frame, npii this on the trunnions of some sections installed thrust plate.

FIG. 1. Depicts the described device, two projections; in fig. 2 - frame, two projections; “And FIG. 3 is a section along A-A and FIG. 2; in fig. 4 - extendable roller conveyor; in fig. 5-section along B-5 and a fig. four.

The device contains a horizontal carrier frame 1, to the lower part of which is attached a swivel 2 and two fixed 3 wheels. The paiMe is mounted on a sliding boom 4, along which the deflecting rollers are placed, and in the upper part there is a guide sleeve 6. The supports 7 and the guides 8 are welded to the upper part of the frame and connected with each other and with a fixed boom handle 9.

Manual winches 10 and // mounted on the boom 4. Winch 10 has a cable 12, at the end of which is installed the yoke 13 with a load 14. The winch // cable 15 is attached to the sliding roller table 16.

The roller conveyor 16 consists of separate sections 17, on the ends of which the pivots 18 are welded. On each axle there is a freely rotating bearing 19. The sections are alternately connected by a plate 20 with elongated holes and a plate 21 with centrally oriented holes. Plate roll ts on pins with a shcheyboy 22, sleeve 23 n

pin 24. At certain intervals on the collet pads, thrust washers 25 were installed, filled with a stop ring 26. The device operates as follows.

Before the load is lifted, the extendable roller table with a cable 15n of a manual winch 11 is moved: along guides 8 in verx, its extreme position, in which it is fixed against accidental self-lowering. The device in front of itself, by the handle 9, is directed towards the load in such a way that the load is placed in the center of the frame / and at the same time is under the crosshead 13. Pro, the load is loaded with the crosshead, lifted by a hand winch 10 above the level of the roller table, while the latter is in a horizontal position. Then release the retractable roller table latch and unwind the cable 15 of the manual winch 11, thereby lowering the extendable roller table along the guides 8 to a horizontal position until it stops 7. After confirming the correct position of the extendable roller table relative to the load 14, lower the latter onto the extendable ralgang. The loading of the load is complete, and the device moves the load in the direction and to any desired point. The unloading is done in the following way: and: First, lift the load over the retractable roller table, pull out the extendable roller table in the directions ti vertical position. Then the load is lowered onto the roller conveyor and the device is retracted.

Subject invention

A device for lifting and moving loads, comprising a horizontal support frame on wheels, to which a fixed along-boom with deflecting arms is attached

rollers, and handworkers, characterized in that, in order to increase operational efficiency and ease of operation, it is equipped with an extractable roller table, made in the form of sections with trunnions, connected

plates with alternating long oblong and cylindrical holes, mounted on trunnions with freely rotating bearings moving along rails mounted on the frame, with

This on the collar of some sections installed thrust washers.
