Description

Technical Field

[0001] The utility model relates to the technical field of traction mechanisms, in particular to a traction frame structure. Background Art

[0002] The existing tractor rear traction frame assembly is installed at the rear of the tractor, including a traction rod system for towing agricultural machinery and a suspension support frame for supporting the traction rod system. For the structure of the traction frame, reference can be made to a tractor rear traction frame assembly and a tractor with announcement number CN216915411U, which includes a suspension frame for connecting to the tractor and a traction component for detachably connecting to the tractor to tow agricultural machinery.

[0003] The above-mentioned tractor rear traction frame assembly can complete rear traction, but there are the following technical problems when towing heavier objects:

[0004] When carrying out construction in forest areas, it is necessary to use a tractor to transport the cut tree stumps. The stumps are usually piled on a transport cart. The transport cart is connected to the traction frame at the rear end of the tractor through a steel wire rope at the front end. The tractor drives the transport cart to move. The existing suspension frame and traction assembly are parallel to the ground. When too many stumps are piled, the gravity increases, and the friction between the transport cart and the ground increases, resulting in the installation platform requiring greater energy consumption to drive the transport cart to move. Utility Model Content

[0005] The utility model aims to provide a traction frame structure, which can solve the problem that the welding position between the existing rib plate and the back plate is prone to cracking.

[0007] It is further configured that the towing hook is configured to be D-shaped, away from the mounting plate and with a through opening on the towing hook.

[0008] It is further configured that a plurality of traction hooks are arranged on the mounting plate along the length direction of the mounting plate.

[0009] It is further configured that a transition arc is provided at the connection between the Y-shaped cantilever beam and the inclined beam to reduce stress concentration at the connection between the Y-shaped cantilever beam and the inclined beam.

[0010] It is further configured that the Y-shaped cantilever beam and the oblique beam are integrally configured, and the Y-shaped cantilever beam and the oblique beam are welded and configured as an integral whole.

[0011] It is further configured that the Y-shaped cantilever beam is installed on the mounting platform through a support.

[0012] It is further configured that the support is provided with a circular hole, the Y-shaped cantilever beam is provided with a circular hole, and a pin is provided through the circular hole and the circular hole.

[0013] It is further configured that walking tracks are provided on both sides of the mounting platform, and the walking tracks are symmetrically provided on both sides of the mounting platform.

[0014] It is further configured that a distance is set between the walking tracks, and the distance avoids broken wood or bushes below.

[0015] It is further configured that a lifting ear plate is not fixedly provided on the top of the Y-shaped cantilever beam, and a lifting hole is provided through the lifting ear plate.

[0016] Beneficial effects of one or more of the above technical solutions:

[0017] By obliquely setting a Y-shaped cantilever beam on the mounting platform, setting an inclined beam at the end of the Y-shaped cantilever beam, and evenly distributing a number of traction hooks at the end of the inclined beam, the Y-shaped cantilever beam and the inclined beam form an upward inclined cantilever structure, and multiple traction hooks are connected to the wire rope at the same time. When the crawler track moves forward, the traction always provides an upward inclined pulling force, thereby improving the traction device and reducing transportation energy consumption.

[0028] The specific implementation of this embodiment is described below with reference to the accompanying drawings.

[0029] Reference Figure 1A traction frame structure includes a mounting platform 1, a Y-shaped cantilever beam 2, an inclined beam 3 and a traction hook 6. The Y-shaped cantilever beam 2 is tilted at the end of the mounting platform, and the inclined beam 3 is fixed at the end of the Y-shaped cantilever beam 2. The end of the inclined beam 3 is fixedly provided with a mounting plate 4, and a number of traction hooks 6 are evenly distributed along the mounting plate 4. Due to the conventional pulling method, the force direction formed by the traction structure and the wire rope is parallel to the ground, resulting in the resistance of the transport trolley at the end of the wire rope being balanced by the traction structure, thereby increasing energy consumption. Therefore, an upward inclined cantilever structure is formed by the Y-shaped cantilever beam and the inclined beam, and multiple traction hooks are connected to the wire rope at the same time. During the forward movement of the crawler track, the traction always provides an upward inclined pulling force, thereby improving the traction device and reducing transportation energy consumption.

[0030] The traction hook 6 is set to be D-shaped, away from the mounting plate 4 and with a through hole on the traction hook 6. After the wire rope passes through the through hole, it is fixed and tied in the traction hook 6 at the same time. It is set to be D-shaped to ensure the welding area between the traction hook 6 and the mounting plate 4, further improving the connection strength.

[0031] Several traction hooks 6 are arranged along the length direction of the mounting plate 4 and on the mounting plate 4. Since multiple wood piles are stacked and arranged on the transport trolley, the weight increases. If only a single traction hook 6 is used, the traction hook 6 will break.

[0032] A transition arc is set at the connection between the Y-shaped cantilever beam 2 and the inclined beam 3. The Y-shaped cantilever beam 2 and the inclined beam 3 are set as one body. The Y-shaped cantilever beam 2 and the inclined beam 3 are welded together to reduce stress concentration at the connection between the Y-shaped cantilever beam 2 and the inclined beam 3.

[0033] The Y-shaped cantilever beam 2 is mounted on the mounting platform 1 through the support 8 , and the two branches at the end of the Y-shaped cantilever beam 2 are respectively mounted on the mounting platform 1 through the support 8 , thereby improving the overall strength of the Y-shaped cantilever beam 2 .

[0034] The support 8 has a circular hole, the Y-shaped cantilever beam 2 has a circular hole 21, and a pin 81 is set through the circular hole and the circular hole 21. Before fixing the pin 81, the Y-shaped cantilever beam 2 can be rotated to adjust the angle between the Y-shaped cantilever beam 2 and the ground.

[0035] Since the ground in the forest area is mostly muddy and branches or wood chips may fall on the ground during construction, in order to ensure the smooth movement of the installation platform 1, walking tracks 9 are set on both sides of the installation platform 1. The walking tracks 9 are symmetrically arranged on both sides of the installation platform 1, and a distance is set between the walking tracks 9 to avoid the broken wood or bushes below.

[0036] A lifting lug 5 is not fixedly provided on the top of the Y-shaped cantilever beam 2, and a lifting hole is provided through the lifting lug. When the traction structure is installed, the traction structure can be transferred by lifting.

[0037] The working principle of the traction device is as follows:

[0038] After passing through the through-hole, the steel wire rope is fixedly tied in multiple traction hooks 6 at the same time, and an upward inclined cantilever structure is formed by the Y-shaped cantilever beam and the inclined beam. Multiple traction hooks are connected to the steel wire rope at the same time. When the crawler track moves forward, the traction always provides an upward inclined pulling force.

[0039] Although the above description of the specific implementation methods of the present invention is combined with the accompanying drawings, it does not limit the scope of protection of the present invention. Technical personnel in the relevant field should understand that on the basis of the technical solution of the present invention, various modifications or deformations that can be made by technical personnel in this field without creative work are still within the scope of protection of the present invention.
