Description

Technical Field

[0001] This utility model relates to the field of loader technology, and in particular to an adjustable height loader towing seat. Background Technology

[0002] Loaders are earthmoving machines widely used in construction projects such as highways, railways, buildings, hydropower, ports, and mines. In actual operation, loaders often need to tow different types of trailers or working equipment. The connection height of different towed equipment often varies, but the towing seat height of existing loaders is usually fixed, making it difficult to meet diverse towing needs. When the towing height is mismatched, uneven traction force and unstable connection will occur, which not only reduces work efficiency but may also cause safety hazards such as trailer unhooking, equipment shaking, or even overturning.

[0003] To solve the aforementioned technical problems, there is an urgent need to develop a loader towing seat with adjustable height. Utility Model Content

[0004] In view of the above-mentioned shortcomings and deficiencies of the prior art, this utility model provides an adjustable height loader towing seat, which solves the technical problem of "how to deal with different types of towing equipment and achieve safe, reliable and flexible adjustable connection towing operation" that exists in the current operation of loader towing seats.

[0005] To achieve the above objectives, the main technical solutions adopted by this utility model include:

[0006] This utility model provides an adjustable height loader towing seat. Specifically, the loader towing seat includes a fixed base, a connecting seat, and a U-shaped fixing pin.

[0007] The clamping plate of the fixed base is provided with multiple pairs of first through holes at equal intervals vertically, and the U-shaped component of the connecting seat is provided with two pairs of second through holes that are adapted to the first through holes.

[0008] The U-shaped fixing pin is a structure consisting of a pair of round rods symmetrically fixed to the base; the ends of the round rods are provided with external threads that are adapted to the fixing nuts, and the round rods are fitted into the first through hole and the second through hole.

[0009] Optionally, the mounting base is symmetrically provided with multiple threaded fixing through holes;

[0010] The threaded fixing through hole is used to fix the loader tow seat to the loader.

[0011] Optionally, the clamping plate may have at least four pairs of first through holes.

[0012] Optionally, the U-shaped component can be fitted to the inside of the clamping plate;

[0013] A pair of connecting plates are fixedly provided at the front end of the U-shaped component, and the connecting plates are provided with fixing round holes adapted to the traction pin shaft;

[0014] The connecting plate is used to connect the traction pin to the external structure for traction.

[0015] Optionally, a U-shaped retaining pin is used in conjunction with a retaining nut to structurally fix both the clamping plate and the U-shaped assembly.

[0016] The beneficial effects of this application are as follows:

[0017] In this application, the clamping plate of the fixed base is provided with no less than four pairs of first through holes at equal intervals in a vertical manner, and the U-shaped component of the connecting seat is provided with two pairs of second through holes that are adapted to the first through holes; based on the actual working conditions, the connecting seat can be fixed to the preset position of the fixed base by the U-shaped fixing pin, so as to realize the connection traction operation with flexible adjustment of the connection height;

[0018] In addition, the U-shaped fixing pin is a structure in which a pair of round rods are symmetrically fixed to the base. Since the round rods fit into the first through hole and the second through hole, and the ends of the round rods are provided with external threads that fit into the fixing nut, the aforementioned U-shaped fixing pin structure is simpler and faster to fix than traditional structural fixing components, and the fixing degree is more secure.
