Description

The utility model relates to trackless ground transport, namely to non-driven industrial vehicles, and can be used as a transport truck for loading, moving in open space and unloading technological trucks with cargo, as well as for autonomous use of a part of the structure as a technological truck for moving goods inside workshops and warehouses.

The purpose of the utility model is the expansion of functionality, increasing the reliability and safety of the cargo.

State of the art

Known hand truck containing a frame with wheels and a tilting platform with two stops on the edges and support rollers with bearings, while the frame is equipped with two recesses for the stops of the platform, as well as nests for the rollers of the said platform. (AS USSR No. 34322, CL 63 b, 3, declared. 04/22/1933, publ. 01/31/1934) [1].

In the transport position, the removable platform is supported by the rollers on the nests of the trolley frame, while the rollers fall into the nests and lose their rotation ability, due to which the load is fixed in place. When tilting, the stops fall into the extreme recesses of the frame, while the ends of the platform serve as knurls on one side and the other ends as handles for lifting, and the stops keep the platform from falling off the frame of the cart. Unloading can be done anywhere without an additional unloading area.

The disadvantages of the known carts are the unreliability of securing the cargo during transportation, as well as the possibility of damage to the cargo when the platform is tipped over.

Known loading and unloading device containing a wagon with a roller table having the ability to rearrange in height relative to the platform of the wagon, and a loading platform with a roller table, roller table rollers protrude when loading and unloading from the platform and are lowered flush during transportation (AS USSR No. 50946, CL 63 a, 35; 20 s, 15, declared on July 21, 1936, published on April 30, 1937) [2].

During operation, the wagon is served to the loading platform, on the rolling table of which the cargo prepared for loading is located. Then the live rolls of the wagon are moved to the upper position and loaded, while the load slides along the rollers of the live rolls of the loading platform and the wagon. After loading the live rolls, the carts are lowered to the lower position, as a result of which the load falls on the platform of the cart.

The disadvantages of the known device are the lack of cargo securing on the platform of the cart, as well as the need for an additional loading platform, i.e. the impossibility of autonomous loading - unloading cargo anywhere.

Known devices for transporting and transshipment of goods to the unloading platform, each of which contains a running trolley with a roller table for placing goods and a guard for securing them, a coupling device with a gripper for fixing the trolley relative to the unloading platform, an unloading platform and a locking device placed on it focus interacting with the grip of the coupling device of the truck. (A.S. USSR No. 291821, IPC B62b 3/04, 1969, publ. Bull. No. 4, 1971) [3] and (A.S. USSR No. 1049319, MKI 3 V62B 3/04, 1980 published by Bull. No. 39, 1983) [4].

When the trolley approaches with or without cargo to the unloading platform, the elements of the trolley coupling devices and

the platforms, interacting with each other, fix them and at the same time unlock the trolley and platform barriers, after which loading or unloading of cargo on the truck’s roller table takes place. Then, after the fencing returns to its original position, the latter act on the locking and fixing structural elements and secure the load.

The disadvantages of the known devices are the design complexity due to the presence of many interacting elements, as well as the impossibility of autonomous loading and unloading of goods anywhere without a loading and unloading platform or hoisting mechanism.

A trolley with a lifting - lowering platform is known, comprising a transport platform on wheels, a mechanism for raising and lowering the said platform, and a carriage on rollers with a mechanism for moving the latter along the transport platform. (AS USSR No. 78500, class 63 b, 4, declared March 17, 1949, published January 31, 1950) [5].

During operation, the load is installed on the carriage, the trolley is moved to the place necessary for work, the position of the cargo is regulated in the vertical plane by raising or lowering the platform and in the horizontal plane by moving the trolley and carriage. The trolley can be used, for example, to change the motor-compressor of a tram car and facilitate its installation under the car.

The disadvantages of the known trolley are the lack of cargo securing, as well as the inability to use the carriage for other technological purposes, for example, to repair a motor compressor when moving from one workplace to another, and its loading - unloading on a transport platform.

Known biaxial trolley for transporting vehicle aggregates, comprising a frame with a platform pivotally mounted on it, consisting of at least two articulated sections with latches of relative position, and a movable platform moving along them, two rotary and two non-rotary wheels connected by a system of levers and rods with a persistent link. In addition, the movable platform is equipped with a drive consisting of blocks, cables, a drum, a handle, a tensioner and a leveling block. (AS USSR No. 931558, MKI 3 B62B 3/04, 1979, publ. Bull. No. 20, 1982) [6].

The truck in the transport position is moved to the car mounted on the inspection ditch. Before bringing the cart under the car, the hinged platform is brought into the working (unfolded) position, but left in a suspended state, the car under the car is brought into the required area. Then, with the help of the drive, the movable platform is moved along the guides, while it comes out of contact with the thrust link, which lifts the fixed wheels through a system of levers and rods and the frame, together with the folding platform, is laid on the supporting surface. Next, the movable platform is moved along the guides along the sections of the hinged platform and oriented at the location of the dismantled unit. After removal and installation of the unit on the mobile platform, reverse manipulations are performed - they move the mobile platform to its original position, bring the fixed wheels to the transport, and the folding platform to the suspended position. Then the trolley is rolled out from under the car, the folding platform is brought into the transport position by folding sections, after which the trolley is transported to its destination.

The disadvantages of the known carts are the design complexity due to the presence of many interacting elements, as well as the inability to use a movable platform for other technological purposes, for example, for repair, maintenance, etc. unit at

moving from one workplace to another and its loading - unloading on a transport trolley.

The closest in technical essence and the achieved result to the claimed device selected trolley for transporting units according to the USSR Copyright Certificate No. 582127, MKI 2 V62V 3/04; B60S 9/00, 1976, publ. Bull. No. 44, 1977 [7].

The trolley, selected as a prototype, contains a frame with wheels, a folding platform with a latch pivotally mounted on the frame, guides on the frame and platform, and a movable platform on rollers to accommodate the load, with the possibility of movement in the said guides.

Cart - prototype works as follows.

The transported unit (cargo) is installed on a movable platform, standing on rollers in the guide rails of the frame. The folding platform is fixed in the transport (raised) position. The truck with the unit is moved to the place of car repair. At the ditch-type repair post, the hinged platform is lowered, having previously released the latch, and brought under the car so that it overlaps the ditch in the place where the installed unit is to be fed. The movable platform with the unit is rolled from the frame rails to the rails of the folding platform. Then install and fix the unit in a regular place. Transportation of the removed unit is carried out in the reverse order.

Trolley - prototype allows you to facilitate the installation and dismantling of vehicle units mounted on the inspection ditch, and at the same time ensure safety conditions, however, such a trolley has disadvantages:

- lack of fixation of the unit (cargo) on the movable platform and the movable platform itself on the frame during transportation to the place of work;

- the inability to use the mobile platform for other technological purposes, for example, for repair, prevention, etc. unit when moving from one workplace to another, since a movable platform without a handle with fixed rollers is not intended for stand-alone operation as a technological trolley for in-shop transportation.

The purpose of the utility model is to expand functionality by using a frame with large-diameter wheels and a folding platform as a transport trolley for inter-workshop transportation of technological trolleys with cargo in open space, and a movable platform as a technological trolley for intra-workshop transportation of units (cargo) from one workplace to another, as well as improving the reliability and safety of cargo during transportation.

This goal is achieved by the fact that in the device for transporting and transshipment of goods containing a frame with wheels, a handle and latches, a folding platform, guides on the frame and platform and a movable platform on wheels with the ability to move in the said guides, the folding platform is made in the form of two ramps - guides pivotally mounted on the end of the frame on a common axis, with the possibility of rotation around it, axial movement independently of each other, docking with the frame guides and laying along the latter in a horizontal position, and the guide ramps are equipped with grips fixed at one end and interacting with the rear of the movable platform when turning the guide ramps around the axis and with grooves at the other ends interacting with the latches on the frame, when the said ramps are in horizontal position, guides on the frame have adjustable stops - catchers interacting

with the front of the movable platform, the latter has load locks and a handle, and its wheels are rotary.

Utility Model Disclosure

The problem to which the utility model is directed is as follows.

For the repair, adjustment, testing and intra-workshop transportation of blocks, devices, complexes, etc. (hereinafter referred to as work objects) technological carts are used from one workplace to another.

The objects of work are fixed with the help of devices on the mentioned technological trolleys, and for each object of work a separate trolley is used, on which the object goes through the entire cycle of work up to testing and packaging. These trolleys have small dimensions (1200 × 750 × 180 mm), including the small diameter of the wheels (150 mm) and are not intended for inter-workshop transportation in open space.

With large volumes of repair, maintenance and adjustment work, there is a need for inter-workshop transportation in open space to involve more jobs of various profiles located in different workshops. For this type of transportation, transport trolleys are used, in which larger diameter wheels are used and the trolleys have appropriate dimensions to facilitate manual transportation and ensure stability for the safety of work objects. However, due to the increased dimensions compared to technological trolleys, transport trolleys cannot be used for intra-workshop transportation due to the limited size of passageways in workshops between workstations.

The reloading of work objects from technological carts to transport is labor-intensive and requires the presence of hoisting mechanisms located in the open

space at the exit of the shops. In addition, it is not advisable to use a transport trolley for each work object only to cover the distance between the workshops.

The best way to solve this problem is to use one transport trolley with wheels of increased diameter (400-500 mm) with the possibility of loading technological trolleys with objects of work, transportation and unloading on it in the required place. At the same time, such a transport trolley should be able to load and unload technological trolleys without additional loading and unloading platforms and load-lifting mechanisms and reliably fix the mentioned technological trolleys during transportation.

The technical result in the implementation of the utility model, in comparison with the prototype, is to expand the functionality by using a frame with large diameter wheels as a transport trolley for inter-workshop transportation of technological trolleys with objects of work in open space, and a movable platform as a technological trolley for intra-workshop transportation of work objects from one workplace to another, as well as improving the reliability and safety of work objects during transport This is done by introducing the fixation of the latter on the movable platform and the fixation of the movable platform itself with stops - catchers and grips when bringing the ramps into the transport position, i.e. when turning them in a vertical plane and laying along the guide rails of the frame in a horizontal plane, followed by locking with clamps on the frame.
