SE508820C2 - Arrangement with diagonal plough with planing function - Google Patents

Abstract

The arrangement is for a diagonal plough with planing function, used for freeing and moving snow and ice from roads, runways and similar areas, the plough being tiltable so as to match the cutting angle to the ground. At the same time, the plough width can be altered by the plough vane (1) being moved to the side as required near the ice and snow which is to be moved away from the ground surface.

Description

15 20 25 30 35 40 45 508 820 In many contexts it can mean extensive advantages to be able to replace the planer steel in the diagonal plow to cutting steel and vice versa. This possibility does not exist in the conventional diagonal plows due to the fact that the cutting angle cannot be changed during the journey. It is thanks to the possibilities to change the cutting angle that the diagonal plow can be supplemented with some planer furilction when required.

By making a change in the cutting angle of the steel, the steel crawls under the ice and snow cover, with which the track is cleaned better and more cost-effectively.

Due to the positive cutting angle, the lateral forces on the base vehicle are significantly reduced by the cutting steel being pressed under the snow for fi-making and then lifted up and thrown away by the arched plow blade. During periods of unfrozen roads, autumn and spring, the insert of the diagonal plow lies a little above the road surface by tilting the diagonal plow and the wear steel abuts against the road surface and smoothes the remaining snow towards the road surface which does not remove the diagonal plow insert.

The present invention aims to facilitate the release and removal of ice and snow from substrates where required. The invention means that diagonal plows can also be used for planing functions, which simplifies the operations and otherwise becomes more cost-effective. In addition, the invention makes it possible to regulate the cutting angle of the diagonal plow from the cab continuously during plowing / planing and to increase the plow width by displacing the diagonal plow laterally, which means that double plowing can be avoided, i.e. that the plow truck only needs to be towed on the relevant stretch once, not as normally back and forth, with large time delays as a result.

KWEÜ. The above objects and further objects are achieved in that the device according to the invention has the features stated in the appended claims.

The device according to the invention is thus essentially characterized in that the diagonal plow is provided with devices which make it possible to tilt the diagonal plow as required without the cutting steel getting stuck or hooked into the ground. The cutting steel will be continuously “read” by the substrate, whereby the positive angle is adapted to the substrate. Plowing at road junctions is facilitated by the diagonal plow being able to be displaced laterally and thus the accumulation of snow and ice can be transported further out from the road junction to avoid time-consuming double plowing. indication from the diagonal plow continuously shows the cutting angle for the driver who can thereby adjust the cutting angle fi from the driver's seat to the ground and ice and snow conditions on the current stretch and adjust the lateral displacement of the diagonal plow to the width of the road.

The cutting steel in the diagonal plow can be replaced with planer steel when required. 10 15 20 25 30 35 40 45 508 820 Brief description of the accompanying drawings.

Detailed description of the invention.

Fig. 1 describes the assembly of the components that make up the diagonal plow with a planer friction according to the invention.

The plow wing (1) collects the ice and snow masses released from the razor / cutting steel web (2), after which the ice and snow masses are thrown out of the web to a suitable distance from the web.

To vary the cutting angle in relation to the track, the plow wing (1) is equipped with a cylinder (3) which tilts the plow wing (1) with the result that the cutting angle changes in relation to the road surface. Cylinder (3) is fixed partly in the plow wing (1) in the attachment point (4) and partly in the profile (5) which connects the plow wing (1) to the coupling rod (6).

Cylinder (3) is equipped with a shock valve, which means that the plow wing (1) can be turned upwards if an obstacle arises on the road surface.

The plow wing (1) is connected to the coupling rod (6) with an additional profile (7).

Problems (5) and (7) have joints (8), (9), (10) and (11) for the plow wing (1) to be able to be displaced laterally by means of a cylinder (13) in relation to the coupling rod (6). .

Since the bolts (5) and (7) lie below an imaginary line (32) between the plow vehicle and the cutting steel (2), this means that the plow wing (1) does not get stuck in the ground in the event of any obstacles, e.g. a stone. In the event of a collision with an obstacle on the road surface, the entire plow wing is lifted upwards by the problems (5) and (7) being below the line (32).

During periods when the plow wing (1) is not connected to the plow truck, the plow stand (20) can be located, which is an intermediate link between the coupling rod (6) and the plow truck, connected to the parking bar (14) so that the plow stand (20) does not slide over the diagonal plow link arms. Fig. 2 shows in perspective the cutting angle (15) between the base and the planer / cutting steel (2) which are fixedly mounted in the lower part of the plow wing (1) in the fastening means (16). The cutting steel can be replaced with planer steel / ice shredder steel as required.

With cylinder (3), Fig. 1, the driver of the plow truck can change the cutting angle as required from his cab by influencing the oil flow in cylinder (3). The sliding steel (17) abuts the road surface during the entire plowing process when the road surface is unfrozen in order to level out the snow after the road surface in the case of frozen roads.

Fig. 3 illustrates how the plow wing (1) can be displaced laterally to the position (19) by means of a cylinder (13) as a result of the bodies (5) and (7) being articulated in the points (8), (9), (10) and (11). The lateral displacement occurs when ice and snow masses are to be moved longer distances, such as during plowing of road crossings and when plowing wide roadways where the diagonal plow is pushed sideways to the left to optimize the plowing process.

Fig. 4 shows a plow stand (20) which interconnects the plow truck in e.g. the brackets (21) and the diagonal plow profiles (5) and (7) via the coupling rod (6). Because the problems (5) and (7) are articulated in points (8), (9), (10) and (11), lateral drying of the diagonal plow can be performed by, among other things, cylinder (13).

Fig. 5 shows one of the joints (8) or (11) which connects the profiles (5) or (7) to the coupling rod (6) which in turn is interconnected with the plow stand (20) and further with the plow truck. The joints (8) and (9) are designed so that the profile (7) can be guided in the horizontal direction of the inner joint (22) at the same time as the profile (7) can rotate in the outer joint (23).

The coupling between the diagonal plow and the plow wing (1) means that the diagonal plow can be moved in both the horizontal and vertical directions at the same time as the diagonal plow can be displaced laterally. Because the outer joint (23) can be rotated, and the diagonal plow can be changed horizontally and vertically, this means that cutting steel (2), Fig. 1, during the entire operation with ice and / or snow removal follows the substrate's variations, e.g. a road may be higher on one side of the road than it is on the other side of the road.

Fig. 6 shows how the cutting angle (15), Fig. 2, is continuously checked from the driving position while plowing is in progress, at the same time as changes in the cutting angle can also be carried out during ongoing plowing. The cutting angle (15) is indicated by LEDs in the box (24) shining continuously through the holes (25) in the rod (26) which are anchored to the profile (5) or (7). Each time the driver changes the cutting angle by acting on the cylinder (3), Fig. 1, the plow wing (1) is moved, with the result that the rod (26) also runs in the fitting device (27), with which another hole comes from the LED in the box (24).

The driver of the plow truck observes which hole the light beam comes through and thus receives information about the cutting angle. The driver can also determine from experience which cutting angle is useful at the specific time and set the intended cutting angle through light signals. Fig. 7 shows how the wear of the planer / cutting steel forms a knife-like edge (28) which has great advantages when ice and snow are to be released from the web (29), at the same time as the knife-like design reduces the risks for jamming. The diagonal plow with components is mounted against the road surface on wheels (30) or with so-called plates which in turn are suspended in the profiles (31) connected to the plow wing (1) and cutting / planer steel (2). Via the wheel (30) and the tilt direction of the diagonal plow, the diagonal plow (1) can be lifted with considerable pressure reduction on the front axle of the base vehicle.

In the development perspective, there are many variations to the execution and use of the invention within the scope of the inventive concept.
