Description

The utility model relates to lifting and transport equipment used in conjunction with lifting structures for loading and unloading large-sized heavy loads with an indefinite center of gravity.

The closest analogue in design, technical essence and result to the utility model is a traverse (patent No. 199916 "Traverse with a screw mechanism"), which is a load-gripping device for precise movement in space of various large-sized cargoes with a variable center of mass using various connecting elements: suspensions , rope and chain branches, textile slings, eccentric grips for sheets, etc., attached to the lifting brackets of the traverse.

The disadvantages of a similar traverse are:

inability to balance the lifted load in the transverse direction;

the difficulty of carrying out the necessary visual and measuring control of the technical condition during the operation of the traverse.

The technical problem solved by the proposed utility model is to eliminate these problems.

The objectives of the proposed utility model is to create an inexpensive and manufacturable traverse that provides the ability to balance the lifted load, both in the longitudinal and transverse directions,

The problem is solved due to the fact that the utility model has a screw mechanism with roller bearings for moving the slider in the transverse direction and a device with roller bearings for moving the screw mechanism in the longitudinal direction, which allows you to move the slider and the screw mechanism without jamming when balancing the traverse with a raised load ( product) having a variable center of mass, and rope branches, allowing constant visual control of the adjustment of the balance of the loads.

The proposed utility model has structural simplicity, accuracy, and reliable operation. The design of the load-bearing elements of the utility model - beams, sliders, rope branches.

In FIG. 1 shows a general view of a traverse with a load in isometric projection.

In FIG. 2 shows the screw mechanism of the traverse. In FIG. 3 shows a rope branch.

The traverse consists of a beam 1 (Fig. 1), a screw mechanism 2 (Fig. 1), four rope branches 3 (Fig. 1), a handle for longitudinal movement 4 (Fig. 1), a screw 5 (Fig. 1). Load 6 (Fig. 1) is attached to the shackles using rope branches, which consist of a steel rope 12 (Fig. 3), thimble 13 (Fig. 3) and a hook 14 (Fig. 3). Rope branches are attached to the traverse beam through transitional links.

The traverse is hung on the hook of the lifting mechanism for the slider 7 (Fig. 2) of the screw mechanism 2, which is installed using carriages 8, 9 (Fig. 2) in the center of the beam 1. The slider 7 of the screw mechanism 2 has rolling bearings for moving in guides and can it is easy to install above the center of gravity of the lifted load 6 by turning the screw 10 (Fig. 2) by the handle for transverse movement 11 (Fig. 2).

The screw mechanism 2 has the ability to move along the beam 1 using carriages 8, 9. The screw mechanism 2 is set in motion with the help of a handle for longitudinal movement 4 along the screw 5 (Fig. 1).

Load 6 during lifting and moving is held by the shackles.

Lifting and moving the load with a traverse is carried out in the following order:

1) before lifting, by rotating the corresponding handles, install the screw mechanism 2 in the center of the beam 1 and the slider 7 in the center of the screw mechanism 2;

2) while controlling the lifting mechanism, connect the upper load-carrying pin of the slider 7 of the screw mechanism 2 with the hook of the lifting mechanism and, after making sure that the latch of the lifting mechanism hook is activated, raise the empty crosshead to a height of 50 to 100 mm to check its balance;

3) in the absence of balance of the empty traverse, without lowering the traverse, by moving the screw mechanism 2 along the beam 1 and the slider 7 in the screw mechanism 2 towards the heavier (lower) end, achieve the balance of the empty traverse in the longitudinal and transverse directions;

4) while controlling the load-lifting mechanism, attach the rope branches 3 of the traverse with the lifted load 6;

5) raise the load 6 to a height of 50 to 100 mm to check the reliability of the braking device of the lifting mechanism and the balance of the traverse;

6) in case of deviation of the loaded traverse from the horizontal position, lower the load and, without disconnecting the traverse from the hook of the lifting mechanism, by moving the screw mechanism 2 along the beam 1 and the slider 7 in the screw mechanism 2 towards the heavier (lower) end, achieve the balance of the loaded traverse in the longitudinal and transverse direction

7) move the load 6 in the required direction and, having freed the traverse from the load being lifted, balance the empty traverse;

8) while operating the lifting mechanism, place the empty traverse in a special place for storage in between work;

9) disconnect the empty traverse from the hook of the lifting mechanism and, if necessary, clean it from dust and dirt.

Thus, the proposed traverse provides the possibility of quick, convenient, reliable, safe regulation of the position of the load, and will also improve the accuracy of balancing and moving the lifted loads, both in the transverse and longitudinal directions, without removing the traverse from the hook of the lifting mechanism.
