Description

Technical Field

[0001] The utility model relates to the technical field of sports fitness equipment, in particular to a tug-of-war training device. Background Art

[0002] Tug of war is a team sport. Its basic rules are that two teams stand on either side of a rope at one end, and then compete for the strength to pull the rope. The team with greater strength will pull the other team across the center line or within the specified area to win the game. This sport usually requires teamwork and solidarity. However, due to the lack of relevant training equipment, athletes cannot conduct systematic and effective training, so that technical details cannot be fully exercised, thereby reducing the overall technical level and being unable to conduct sufficient strength training. At the same time, the lack of data provided by relevant training equipment means that there is a lack of detailed data support when formulating training plans. This affects the technical level and strength level of athletes, and may also increase safety risks in training and competition, reducing the overall training effect and team competitiveness.

[0003] Currently available tug-of-war training equipment uses only one column as a tension support. In order to maintain horizontal tension, the counterweight can only move in a small range at half the height of the column, which makes it difficult to achieve the training effect of repeated wrestling in tug-of-war training and easily damages the column, causing safety hazards. If the weight is removed, it can only be used as a tension column, which is not practical. Utility Model Content

[0004] The utility model aims to provide a tug-of-war training device with a multi-stage design to solve the above-mentioned background technical problems.

[0005] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: a tug-of-war training device with a multi-stage design, comprising: a main frame, the main frame is connected by four columns to support a top plate, and a pulley assembly is connected to a central opening of the top plate of the main frame;

[0025] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0026] The main frame 1 has the characteristics of solidity and stability. The main frame is 2.5 meters long, 2.5 meters wide and 4 meters high, and is divided into four key parts. Four sets of columns 6 made of 25# I-beams constitute the main support. The bottom fixing plate and the upper connecting plate are made of durable Q235 steel plates to ensure the firmness of the structure. The four beams 7 are made of 10# channel steel, which are welded together by the connecting plates and channel steel at both ends to form a whole, thereby enhancing the overall strength of the column. The top plate 5 is connected to the column 6 at four corners, and the column is at an angle of 77° with the ground to improve the stability of the column. The pulley assembly 8 is equipped with two UCF208 bearings to ensure the smooth movement of the column during use. During the overall assembly, the column, beam and top plate are firmly connected together with M12 bolts to form a structure that is narrow at the top and wide at the bottom, making the main frame more stable at the bottom. This design can bear a load of 5 tons. In order to ensure safety, the bottom of the pillar 6 is firmly fixed to the ground with 6 M14 expansion bolts, which effectively prevents the movement of the column and resists a certain degree of impact.

[0027] The high auxiliary frame 2 is 680mm long, 600mm wide and 780mm high, and includes 1 main frame, 1 set of pulley assembly 8 and 1 set of roller assembly 9: the panel is made of Q235 steel plate with a thickness of 16mm, and a solid overall structure is formed by welding. The main design includes the pulley assembly 8 and the roller assembly 9, in which the pulley assembly 8 is composed of a pulley with a diameter of ￠180x110, a center shaft of ￠50x300 and two UCF208 bearings. The roller assembly 9 includes a chrome-plated steel roller of ￠50x210 and two UCP206 bearings. These two components are firmly mounted on the auxiliary frame body by M12 bolts. During the installation process, 12 M14 expansion bolts are used to fix the auxiliary frame as a whole to the ground to ensure the stability of the frame. This design not only takes into account the solidity of the structure, but also pays attention to the stability during the installation process, providing reliable support for actual use.

[0028] The low auxiliary frame 3 has a more compact design, with dimensions of 680mm in length, 600mm in width, and 680mm in height, and is mainly composed of a square tube 50x50x3.0mm and an angle steel 50x50x5.0mm. The main frame is equipped with a pulley assembly 8 and a rope threading hole 12. The pulley assembly 8 uses a pulley with a diameter of ￠180x110, a central axis of ￠50x300, and is equipped with two UCF208 bearings. The entire low auxiliary frame has a compact structure, is easy to carry and arrange, and has the same pressure and impact resistance stability as the high auxiliary frame 2.

[0029] The equipment's weight 4 is suitable for a variety of training scenarios for 1 to 12 people. It adopts a split mode, with a weight range of 1 kg to 900 kg, with each 50 kg level, ensuring that the trainer can choose the appropriate load according to individual circumstances. After fully weighted assembly, the equipment size is 800mm long, 500mm thick, and 550mm high. A buffer 16 is added to the bottom to prevent the weight from falling and wearing, ensuring the stability and durability of the equipment.

[0030] The tension rope connected to the counterweight 4 passes through the pulley assembly 8 installed on the top plate 5 of the main frame 1, and downwardly passes through the pulley assembly 8 and the roller assembly 9 on the high auxiliary frame 2, and then passes through the pulley assembly 8 of the low auxiliary frame 3, and passes through the rope threading hole 12 to form a complete trainer.
