Description

Technical Field

[0001] The utility model belongs to the field of connecting pieces, and relates to a hydraulic vehicle head and tail end connecting piece. Background Art

[0002] Polyester pre-oriented yarn (POY), the raw material for chemical fiber, is processed into drawn textured yarn (DTY) through a texturing machine, which then meets the needs of clothing, home furnishings and industry. The safe and efficient transportation of POY packaging pallet yarn has always been a problem that has plagued factory production management.

[0003] Patent CN105905154A discloses a manual hydraulic transport vehicle, including a handle, a cylinder body, a large piston rod, a small piston rod, a support body, a rear wheel, a rear connecting rod, a vehicle body, a front connecting rod, and a front support body; the front support body includes a support body, a ball, a rolling ball, and a pressure cover, the support body is provided with a spherical groove, the rolling ball is placed in the spherical groove, and a plurality of balls are placed between the spherical groove and the rolling ball. The pressure cover is provided with a circular hole at a position corresponding to the rolling ball. The pressure cover is connected to the support body by screws to confine the ball and the rolling ball in the spherical groove, and a part of the rolling ball contacts the ground through the pressure cover; the patent adopts a new driving wheel structure, which can freely change the driving direction of the vehicle according to the direction of the driving force, and reduce the output of traction force of the consignor when the vehicle turns.

[0004] Patent CN104309656A discloses a manual load-carrying hydraulic cart, including: a hydraulic cart base, a universal roller, an adjustment column and a fastening bolt. The hydraulic cart base includes a pair of symmetrically arranged fork plates, a directional wheel is arranged at the bottom of the front end of the fork plate, the universal roller is arranged at the bottom of the end of the fork plate, a vertical through hole is arranged at the end of the fork plate, the adjustment column passes through the through hole and is connected to the top of the universal roller, a threaded hole is arranged on one side of the end of the fork plate and is connected to the through hole, and the fastening bolt is arranged in the threaded hole. The hydraulic cart of this patent can adjust the height of the universal roller when carrying heavy objects, especially heavy objects with offset center of gravity, so that the universal rollers on both sides provide additional support and improve the stability of transportation.

[0005] The hydraulic vehicles disclosed in the above patents are all common hydraulic vehicles on the market, with different advantages. However, when these hydraulic vehicles are used to transport POY packaging pallet yarns in traditional texturizing workshops, many inconveniences will occur. For example, the ATF-1500 texturizing machine of TMT Chemical Fiber Equipment Company has 384 spindles per machine, and the packaging POY is calculated at 36 pieces / piece, with an average of about 11 pieces per machine. According to normal production, a certain scale of texturizing workshop has a daily machine capacity of about 370 packages of POY packaging pallet yarns. When these common hydraulic vehicles (which can only be used by one person per vehicle) are used to transport POY packaging pallet yarns, 740 round trips are required from the storage warehouse to the production machine, which is a large workload and low efficiency. The frequent shuttling of forklifts will bring more safety hazards.

[0006] Therefore, it is of great significance to study a connector that can connect ordinary hydraulic vehicles in series to achieve the transportation of multiple POY packaging pallets in one go. Utility Model Content
