Description

The utility model relates to the field of lifting equipment and is intended for loading, unloading and transportation of large-sized products, including pipes of small and large diameter, various products of cylindrical shape, etc.

A number of analogues of both domestic and foreign development are known (see, for example, applications 2268152 and 2292929-2292932 of Great Britain, В60Р 1/54 and Е02F 3/32 dated January 5, 94 and March 13, 1996, as well as US Pat. 2019486 and 500886 Sweden, В65G 67/12 and В62D 61/10 dated September 15, 94 and September 26, 94, the express information on which is given in the corresponding publications 3.69.32P, 3.69.33P, 7.69.37P on pages 4 and 5 RZH 69 "Technology and equipment of logging, woodworking and pulp and paper production", No. 3 and 7 for 1995 and publications 9.60.68P-9.60.71P on pages 7, 8 of RZh 60 "Construction and road machines" No. 9 for 1997, Moscow: VINITI, and other).

Some of them are used as autonomous loading modules, while others are equipped with appropriate loading platforms, most often trailed, limiting the maneuverability of the machine in production areas with narrow passages and small (cramped) work platforms.

A number of these well-known machines are quite complicated in design and have insufficient stability against overturning when performing loading and unloading operations with an unhooked cargo platform, and in many others the fixation of the boom and the corresponding working body pivotally mounted on it, mounted on a load-bearing carrier frame in a transport vehicle position, does not provide reliable locking them when the machine moves on rough terrain and sharp turns, ease of maintenance, etc.

The limited size of the rear half frame of most general-purpose vehicles to a large extent complicates the installation of manipulative-type lifting equipment with a multi-section boom and the corresponding hydraulic drive on it, the formation of the necessary service areas for the latter on it, and also eliminates the possibility of using bulky products for transportation, including small and large diameter, various cylindrical products, etc.

The known loader is mainly timber, created on the basis of a tractor with an articulated bearing frame, equipped with appropriate hydraulic hoisting devices of manipulator type. In the loader, the rear tractor semi-frame was modified by docking the corresponding extension attachment to it, and it has a spatially developed subframe with two autonomous support modules placed on it, a hydraulic manipulator, a support for fixing the boom and grab of the latter in the transport position and the necessary service areas and other equipment. According to the applicant, the technical solution improves the technical and operational qualities of the loader (RU 2230698, IPC V66C 23/36, B66F 9/06, 06/20/2004).

In the transport position, the lifting and remote sections of the boom of the hydraulic manipulator are folded (pulled to each other) and are located above the tractor cab along the longitudinal axis of symmetry in the direction of its movement and are fixed by a grab on the support by gripping the jaw that is formed in its upper part for this bracket, oriented in longitudinal direction. This transport situation does not meet the requirements of air transport and railway transportation due to the large size. There is no possibility of using a loader for transportation of large-sized products, including pipes of small and large diameter.

Known jib crane containing the base of the columns, mounted on the body and trailer of the car in the places necessary for maintenance and two telescopically mounted alternately on them the head of the columns. The top of each head is made in the form of an open rectangle. The bearing assembly, by means of which the boom is mounted on the column head, includes a housing with a hollow rectangle fixed through the console, which is inserted into the open rectangle and locked with it in the working position with a finger. A worm wheel is fixed on the hollow axis of the bearing assembly, which interacts with the worm fixed on the housing, during rotation of which the handle rotates the boom in a horizontal plane and fixes it. The rope at the end of which the cargo hook is fixed is stored through a rope block mounted on a clamp with the possibility of fixing in various places on the boom and the rope block passed through the hollow axis is stored between two rope blocks. The other end of the rope is wound and mounted on a drum with a brake in the form of a safe handle. The brake handle is mounted on one end of the brake shaft, and its other end is made with splines (RU 2097307, IPC В66С 23/44, 11.27.1997).

The disadvantages of this technical solution are the large size and the inability to transform the crane from its working position to transport and vice versa without dismantling the entire structure. The loss of stability of the crane during loading and unloading is not ruled out due to the lack of means to increase the support contour of the crane.

The objective of the utility model is to create a crane - a transformer, combining the functions of a trailer for the transportation of bulky goods and a loading and unloading machine for autonomous lifting, lowering and moving goods to heights.

The technical result of the utility model is to reduce the size and expand the functionality of the device by combining the transportation of goods and handling, as well as transforming from the working position to the transport one and vice versa without dismantling the structure.

The specified technical result is achieved by the fact that in the jib crane, which is mounted on a movable base with the possibility of rotation in a horizontal plane and fixation, an arrow with a cable block and a drive, said movable base is made in the form of a low loader trailer with a fixed part, a rotary platform and working equipment, not fixed the part contains a lower frame integrated into the metal structure of the low loader trailer, having a support platform (“gander”) with a support ring for installing the rotary plates the form, which includes a transformable rotary frame with a ring for the formation of the support-rotary device together with the support ring "gander", the mechanism of transformation of the rotary frame to convert from the folded state to the deployed, the rotation mechanism, the mechanism for changing the departure and the node for installing working equipment, made in the form of a sectional telescopic boom and a cargo winch, fixed behind the root section of the boom.

In addition, the drive is located on the supporting platform of the trailer ("gander") and is made in the form of a hydraulic system with a stationary pump driven by a stationary engine to control the fixed part.

In addition, on the non-rotatable part of the low loader trailer, brackets are made for the beams of the front and rear rotary supports.

In addition, at least part of the supports have extendable sections.

The utility model is illustrated by drawings.

In FIG. 1 shows a general view of a jib boom trailer.

In FIG. 2 shows a jib boom trailer crane in working position.

In FIG. 3 shows a jib autonomous trailer crane in a transport position.

The jib autonomous crane trailer (see Fig. 1) contains a boom 2 mounted on a horizontal base and rotated in a horizontal plane and fixed with a rope unit 3 and a drive 4. The movable base is made in the form of a low loader trailer 1 with a fixed part 5, the rotary platform 6 and the working equipment 7, the non-rotatable part 5 comprises a lower frame 8 integrated in the metal structure of the low loader trailer, having a support platform (“gander”) 9 with a support ring 10 for mounting the rotary platform, which includes I transform the rotary frame 11 with the ring 12 for the formation of the support-rotary device together with the support ring 10 of the “gander”, the transformation mechanism of the rotary frame 13 for transfer from the folded state to the deployed one, the rotation mechanism 14, the mechanism for changing the offset 15 and the assembly 16 for installing the working equipment 7, made in the form of a sectional telescopic boom 2 and a cargo winch 3 (cable block), mounted behind the root section 17 of the boom.

This combination of features, their implementation and relative positioning and communication provides a significant reduction in size (see Fig. 3) and the expansion of the device’s functionality by combining the ability to transport goods and autonomize loading and unloading operations, as well as transforming them from the working position (see Fig. . 2) in transport and vice versa without dismantling the structure.

On the supporting platform of the trailer 9 ("gander") are a hydraulic system with a stationary pump, driven by a stationary engine 18 to control the fixed part, which provides additional mobility and autonomy of the device.

On the non-rotatable part 5 of the low loader trailer, brackets 19 are made for the beams of the front 20 and rear 21 rotary supports controlled by hydraulic cylinders 22.

At least some of the supports have retractable sections 23, which further increases the crane's support contour, increasing its stability during loading and unloading.

The specific implementation and operation of the crane is presented below. A jib crane with a load moment of up to 100 tons on a low loader trailer consists of a fixed part, a rotary platform and working equipment - an arrow.

The non-rotating part will include a lower frame with a support ring for the installation of a support-rotary device (hereinafter - OPU), integrated directly into the metal structure of a low loader trailer, with brackets for the beams of the front and rear rotary supports, and a stationary engine. The support ring under the OPU is located on the "gander" (supporting platform) of the trailer.

Front and rear swivel bearings are put into working position by hydraulic cylinders and are held by them during crane operations. To increase the support contour, the supports have the ability to increase the length of the beam due to the sliding sections of the supports.

The non-rotating part is controlled from an independent hydraulic system with a stationary pump driven by a stationary engine located on the gander (supporting platform) of the trailer.

The pivoting platform includes a transformable pivoting frame with a ring for installing the control gear and places for installing the boom, a mechanism for transforming the frame (translation from the folded state to the unfolded one), the pivoting mechanism, and the mechanism for changing the departure.

The control of the turntable is carried out from a portable electrical panel using a wired electric or radio signal.

The working equipment is a sectional telescopic boom, consisting of three to five sections, a cargo winch, fixed behind the root section of the boom. The boom sections are made of two half-boxes, butt welded on both sides. Moreover, the upper half-box has two bends of the same radius in all sections, the lower half-box has one radius, decreasing from section to section in the direction from the base to the upper section.

The boom sections are connected to the base via a telescoping hydraulic cylinder, and to each other through a telescoping hydraulic cylinder and a cable-block system.

The declared trailer crane is autonomous, since a hydraulic station is installed on it, which drives the crane mechanisms. After the truck tractor delivers the trailer to its place, it can unhook it and leave, for example, behind another trailer. And the remaining trailer, due to its autonomy, can unload itself and carry out loading and unloading operations to move goods.

Due to the transformable swivel frame, you can control the transport and working dimensions. With the transport dimension, the swivel frame (column in the manipulator) can be lowered to a horizontal position, thereby reducing the height of the trailer crane, which is important for air transport and rail transportation. And for the working position, the frame rises and is converted into a classic version.

Thus, when using the utility model, a technical result is achieved, which is to reduce the size and expand the functionality of the device by combining the transportation of goods and loading and unloading, as well as transforming from a working position to a transport one and vice versa without dismantling the structure.
