Description

Technical Field

[0001] This utility model relates to the field of tractor technology, and in particular to a telescopic tractor. Background Technology

[0002] Traditional tractor units typically use a fixed-length traction structure, and the distance between the chassis and the connecting mechanism is not adjustable, resulting in poor adaptability when transporting equipment or objects of different lengths. For example, the original truck bed length is no more than about 6 meters, and for safety reasons, it cannot carry equipment or objects longer than 6 meters. Especially when transporting extra-long light equipment (such as long cargo weighing less than 5 tons), the fixed-length tractor unit is difficult to meet the needs, often requiring the replacement of specialized transport vehicles or the use of complex auxiliary fixing devices, which increases transportation costs and operational difficulty.

[0003] In the existing technology, there are many modified and installed equipment. Although there are some adjustable length traction devices, their telescopic structure is usually relatively simple and lacks a reliable reinforcement mechanism. They are prone to loosening or displacement when used for a long time or under heavy loads. Moreover, relying on a single telescopic rod for support for a long time can easily cause the frame to deform due to uneven traction or road bumps, affecting transportation safety and stability, and reducing the reliability and durability of the tractor.

Detailed Implementation

[0041] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0042] This utility model provides, for example Figure 1-4 The image shows a telescopic tractor.

[0043] Example 1 includes: a traction mechanism 100, a reinforcing frame 200, a front steel frame 300, a telescopic rod 400, and a connecting mechanism 500. The traction mechanism 100 is used for the traction connection between the vehicle body and the front of the vehicle. The reinforcing frame 200 is fixed to one end of the traction mechanism 100. The front steel frame 300 is installed between the traction mechanism 100 and the reinforcing frame 200. The reinforcing frame 200 is used for the connection and reinforcement between the traction mechanism 100 and the front steel frame 300. The telescopic rod 400 is fixed to one end of the reinforcing frame 200. The telescopic rod 400 is used for the extension and retraction of the tractor. The connecting mechanism 500 is installed to one end of the telescopic rod 400 by bolts. The connecting mechanism 500 is used for the extension and retraction of the telescopic rod 400, so that the tractor can be set in multiple lengths, making it more versatile.

[0044] The traction mechanism 100 includes a traction head 101, a traction frame 102, and a bracket 103. The traction head 101 is used for traction fixation with the front of the vehicle. The traction frame 102 is fixed to one end of the traction head 101, and the bracket 103 is fixed to one end of the traction frame 102. The bracket 103 is fixed to one end of the front steel frame 300, and the reinforcing frame 200 is fixed to the other end of the front steel frame 300. Through the connection between the bracket 103 and the reinforcing frame 200 and the front steel frame 300, the top of the front steel frame 300 can cooperate with the connecting mechanism 500 to support the truck bed. The power output of the engine, clutch, and gearbox of the tractor unit are coordinated through the traction force connected by the traction mechanism 100 to move the front steel frame 300.

[0045] In addition, the connecting mechanism 500 includes a rear steel frame 501, a sleeve 502, and a connecting hole 503. The rear steel frame 501 has a frame structure, and multiple sleeves 502 are fixed parallel to each other on the lower surface of the rear steel frame 501. Multiple connecting holes 503 are respectively opened at the ends of the sleeves 502. The telescopic rod 400 is slidably inserted into the inner cavity of the sleeve 502. One end of the telescopic rod 400 is inserted into the inner cavity of the connecting hole 503 by a bolt. The distance between the front steel frame 300 and the rear steel frame 501 can be adjusted by the insertion and fixing of the bolt at the end of the telescopic rod 400 into the connecting holes 503 at different positions on the sleeve 502. For example, when it is not telescopic, the length between the front steel frame 300 and the rear steel frame 501 is 10 meters. When it is extended, the length between the front steel frame 300 and the rear steel frame 501 can reach 14 meters, which can fully meet the needs of transporting long light equipment (weighing less than 5 tons) and objects on site.

[0046] Example 2, based on Example 1, further includes mounting holes 600 and auxiliary mechanisms 700. Multiple mounting holes 600 are respectively opened at one end of the connecting mechanism 500 and one end of the reinforcing frame 200. The mounting holes 600 are opened at one end of the sleeve 502. The mounting holes 600 have a rectangular groove structure. The auxiliary mechanisms 700 are arranged on both sides of the reinforcing frame 200. The auxiliary mechanisms 700 are used for auxiliary reinforcement between the reinforcing frame 200 and the connecting mechanism 500.

[0047] Furthermore, the auxiliary mechanism 700 includes an auxiliary rod 701, a movable groove 702, a mounting block 703, and a clamping assembly 704. The auxiliary rod 701 is located on the side of the reinforcing frame 200 and is arranged parallel to the adjacent telescopic rod 400. The auxiliary rod 701 is a reinforcing steel plate structure and is fixedly welded to the middle of the front steel frame 300. Multiple movable grooves 702 are respectively opened at both ends of the auxiliary rod 701. The mounting block 703 is located in the inner cavity of the movable groove 702. The mounting block 703 is an integrally formed U-shaped steel block structure, and the two ends of the mounting block 703 are of different lengths. The mounting block 703 is slidably inserted into the inner cavity of the adjacent mounting hole 600. The clamping assembly 704 is located at the top of the movable groove 702 and is used to press down the top of the mounting block 703 to prevent the mounting block 703 from moving arbitrarily and reduce the phenomenon of the mounting block 703 sliding out of the inner cavity of the mounting hole 600.

[0048] Specifically, the movable groove 702 includes a lower sliding groove 721 and an upper sliding groove 722. The lower sliding groove 721 is located at the bottom of the auxiliary rod 701, and the upper sliding groove 722 is diagonally located at the top of the auxiliary rod 701. The mounting block 703 is horizontally slidably connected to the inner cavity of the lower sliding groove 721 and vertically slidably connected to the inner cavity of the upper sliding groove 722. The mounting block 703 will not slide out of the top of the lower sliding groove 721 even when it moves vertically within the inner cavity of the upper sliding groove 722, thus reducing the slippage phenomenon of the mounting block 703. The mounting block 703 can also slide to a certain extent within the upper sliding groove 722, which facilitates the movement of the mounting block 703 to the top of the mounting hole 600 and its insertion into the inner cavity of the mounting hole 600. This improves the connection stability between the auxiliary rod 701 and the adjacent reinforcing frame 200 and sleeve 502, and facilitates the auxiliary reinforcement of the telescopic rod 400, reducing the occurrence of traction deformation. The movable groove 702 adopts a design that combines the lower sliding groove 721 and the upper sliding groove 722 to limit the movement range of the mounting block 703 and prevent it from accidentally slipping off.

[0049] More specifically, the clamping assembly 704 includes a pull rod 741, a compression spring 742, and a pressure plate 743. The pull rod 741 is slidably inserted into the top of the inner wall of the upper sliding groove 722. The compression spring 742 is sleeved on the outer wall of the pull rod 741. The pressure plate 743 is fixed to the bottom of the pull rod 741. The top of the compression spring 742 is fixedly connected to the top of the inner wall of the upper sliding groove 722, and the bottom of the compression spring 742 is fixedly connected to the top of the pressure plate 743. Through the elasticity of the compression spring 742, the pressure plate 743 can be pressed down against the top of the mounting block 703, preventing the mounting block 703 from moving out of the inner cavity of the mounting hole 600 due to vibration. Under normal use of the tractor, the truck bed is in a compressed state against the pull rod 741, further improving the stability of the mounting block 703 position and avoiding the phenomenon that existing tractors are too short to transport longer equipment or objects, thus improving the practicality of the tractor.

[0050] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
