RU2485250C1 - Multipurpose dozer excavator - Google Patents

Abstract

FIELD: transport.

SUBSTANCE: proposed dozer comprises control assembly with adjustment pumping unit communicated via pipelines with hydraulic assemblies, tanks for fuels and lubricants and working fluid, platform, bearing turntable, rotary barrel (with check vale, not shown), two-way hydraulic cylinder, rams with tables, fluid operated telescopic boom articulated with aforesaid platform and drive. Extra turntable is arranged at boom end and connected with aforesaid drive. Extra turntable is compatible with attached implements. Lifting mechanisms with supports are secured in lugs of two-way cylinder secured at bearing table. Speed of displacement of dozer and excavator implements makes 0.5 m/s or 1800 m/h. Efficiency of dozer is two times as high owing to operation without idling, displacement of soil with loading and using piling according to trench profile. Fuel and lubricant savings are ensured result from traction forced higher than 35^th class due to using appropriate power cylinders. Multifunction operation, new soil excavation processes, higher efficiency, savings of fuels and lubricants and lower metal input.

EFFECT: multifunction operation, new soil excavation processes, higher efficiency, savings of fuels and lubricants and lower metal input.

Description

The invention relates to the field of mining, construction and various areas of the national economy, for which various types of working bodies are used, including with a blade of a bulldozer and an excavator bucket, with a grab and with mounting stops of a crane, various equipment used by the Ministry of Emergencies for dismantling debris, elimination of forest fires and clearing the channel of rivers and canals.

The present invention is an improvement of the well-known invention of Russia No. 2394964 "Multifunctional bulldozer excavator", 2009, which contains the equipment of a hydraulic truck crane, a double-sided power hydraulic cylinder, lifting mechanisms with supporting platforms and a drill glass.

The multifunctional work of the prototype, in essence, is determined by the ability to perform a number of works with various attachments that are compatible with an additional turntable located at the end of the boom of a truck crane and connected to the boom by a hinge and a movement mechanism. The circle of work in a circle is limited by the telescoping radius of the boom of crane equipment.

The purpose of the invention is to simplify the running gear.

The goal is achieved, without changing its main characteristics, by eliminating a number of nodes and parts.

A reusable bulldozer excavator contains a control unit with a pump and control unit connected to the hydraulic system by a pipeline 1, a reservoir for fuels and lubricants 2 and a working fluid 3, platform 4, a support turntable 5, a drill 11 (with an RF check valve, not shown), double-sided hydraulic cylinder 8, hydraulic lifts 9 with platforms, a hydraulic, telescopic boom 13 connected to the platform 4 by a hinge 12 and a movement mechanism 14, an additional turntable 16 connected to the boom is placed on the end of the boom rum 15 and the movement mechanism 17, the additional turntable 16 is compatible with a number of attachments, including the blade of the bulldozer and the excavator bucket, with a grab and with mounting stops of the crane, attachments used by the Ministry of Emergency Situations in the liquidation of accidents at drilling rigs, dismantling blockages , when eliminating forest fires, cleaning the bottom of rivers and canals, it differs in that the lifting mechanisms with supports 9 are fixed in the earrings 8 * of the double-sided hydraulic cylinder 8, which is fixed on the supporting platform 10 connected to the pl Site 6 racks 7.

The invention is illustrated by drawings.

Figure 1 is a side view, figure 2 is a rear view.

An example of practical application. The device is delivered to the place of work by trailer, and to remote cities, villages and to the place of forest fires, promptly, by helicopter.

The mechanism for moving a bulldozer excavator works in three cycles. The first cycle is the movement of the installation. The second preparatory and third worker. Figure 1 and 2 shows the initial position of the duty cycle. A prerequisite for 3 cycles is the position of the drill 11 in the ground. The first cycle - movement - occurs under the condition that the drill cup 11 is removed from the ground and the support is mounted on hydraulic lifts with supporting platforms 9. In this case, the working fluid directed into the body of the double-sided hydraulic cylinder 8 moves its body and the whole mechanism connected to it. The second cycle is preparatory, it is carried out with the support resting on the drill ring 11. In this case, it is possible to move only the rods of the hydraulic cylinder 8 with the hydraulic hoists 9 fixed in its earrings 8 *, and also under the influence of the support turntable 5, the choice of the direction of movement.

About the speed of movement. The speed of the hydraulic cylinder rods = 0.5 m per second. taking into account the loss of the same time in the preparatory cycle, the speed will be 0.25 m per second. Performing the tasks of an excavator and a bulldozer, the time required to change the parking position to a distance of 50 m will be 3 minutes 20 seconds. The speed of movement of the working bodies of the bulldozer and excavator is 0.5 m / s or 1800 m / h. The productivity of the bulldozer will increase by 2 times due to the possibility of working without idling, moving soil with loading and using the profile blade along the profile of the trench. Fuel and lubricant savings will be ensured by the ability to create traction above class 35 due to the use of power hydraulic cylinders with an increased piston and high pressure.

Multifunctionality, new technologies of soil development, productivity growth, fuel and lubricants and metal saving gave the basis for the development of applications for the invention in the nomination 100 best.
