Abstract

DC60 (07/08/55) This series of peripherals. Has been designed and developed further. With a mechanism for Locking and unlocking the connection Including a tow loop storage when not in use It consists of two main parts. The first part is the trailer part which consists of the trailer bracket, the trailer loop, the pivot axle set. How to attach the trailer to the cart Will use screws and nuts to attach Match the structure of the trolley that will be used for connecting (If not using screws and nuts to attach to the cart This bracket can be connected to the structure on either side of the cart) when lifting the towing loop. Make a right angle to the ground Will not fall down (Position of retracting the tow loop) and when lifting the loop Towed up so that the pivot point is at the end of the tow loop. This tow hitch can be folded down to the exact same level (position of the towing) caused by the return spring, which is incompatible with the towbar bracket, to support the tow hitch in the available position. (Horizontal plane), the second part is a set of trailer lock bolts It is made up of a C-shaped (C) folded flat steel sheet structure with equal perforation at the top and bottom. And on the sides there is a flap to increase strength and prevent sagging of the structure. At the top Has a pivot point for locking bolts Of the trailer lock set Which is placed vertically down between the top and the bottom through the gap of the line C-shaped structure groove (C) with steel core pin through the lock pin. Serves as a pivot point for the locking bolts, has a very famous mechanism. When a trailer is attached, the latch acts as a latch and The spindle with the arc of the towing loop that is inserted Connection procedure Achieved by pushing the part The bend of the tow hoop pushes the lock pin into the trailer lock frame. Until the longest part of the bolt lock That touches the arc of the drag that is inserted into it The trailer locking bolts are reversed by pulling. Of the spring automatically returns to its original position vertically And in unlocking Can be done with your feet Stepped on the steel pedal (24) at the top end of the bolt lock. In order to make the bolts turn around to avoid The inner arc of the towbar is against the locking pin in the locking position (25), allowing it to reverse. Or pushing the two cars apart conveniently The bolt lock will rebound back to its position. Automatically Towing equipment and locking systems for this towing It has been redesigned and developed in both the towing mechanism and the locking or unlocking of the trailer. By studying from the original that There are various disadvantages. And have gathered problems from real use to the invention of this device. The real-life device is made up of 2 parts: part 1 (the towbar assembly), installed at the bottom of the car, fixed by a screw. And nut Has a steel core structure extending Serves as a towbar to be used in conjunction with part 2 of the towing. It is inserted into the second part, and also has a special mechanism designed for a convenient and easy-to-use position and the folding part of the second part (a set of locking and disconnecting systems). Installed at the bottom of the car (The opposite side of part 1) fixed with screw and nut. There is a section where the towbar can be inserted from another vehicle by pushing and a special mechanism makes the latch pin come down automatically. It is a complete towing between the two cars and when wanting to unlock the lock, just use the feet to step on the latch. The opening case allows the towing rod to be removed from the metal shaft pin of part 2 to separate the two cars

Claims (2)

Disclaimer (all) that will not appear on the advertisement page: hereby claim the "towing equipment and locking system". There is a mechanism for locking or unlocking the conveying system of an industrial plant "," with the characteristics of the special mechanism and the design that comprise this invention. 1. The towbar set (Fig. 1) consists of a U-shaped rebar (10), a steel structure laid across (11) and bonded to increase strength. The other end has a hinge made of steel plate. Welded to the rebar (9) folded into a U-shape It surrounds the spindle (5,6,7) fixed on the steel plate (8) with the effect that when raised at a right angle to the ground. This U-shaped pull handle won't fall down. (Retracted position), and when the pivot position is changed to the end of the towbar unit, this towbar can be folded down. The characteristics of a special mechanism consists of a spin (4) attached to the spindle (1, 2, 3), which is attached to the bottom hinge near the ground (9) as a load. Bump and force the position of the towing unit to be placed parallel to the ground. (Initialization position), which is positioned in a manner ready to tow the trailer. 2. The coupling locking and release system assembly (Fig. 2) consists of a C-shaped sheet (5) on the closed side of the C-body. At the top and bottom There is a drill The grooves are evenly long, and on the sides there is a flap (4) to steer the steering circle for the towbar section, at the farthest side from the cover, the C of the groove has a steel rod (8) that acts as a pin. And core Rotate to fit the drag that was inserted. Is placed vertically down and is longer than the top, and The bottom of this C-shaped steel plate The pivot points surround the axis (9, 10, 11) parallel to the ground. Welds are attached to the top of the C-shaped steel plate. The pivot point of the core (8) above the top of the C-shaped steel plate is slightly folded out and the steel pad (7) is welded. It has the characteristics of a special bell-like mechanism (the atmosphere used to press down on it) at its normal position, the iron core is retained. This is caused by the sping tension (6) between the steel shaft and the bolt assembled from the screw and nut (1,2,3) located close to the near side of the C cover. That is forcing the steel core to be in conflict with the bottom groove of C-shaped steel plate at the far end at all times Which is the correct position of use, with the effect that when the towing begins The end of the towing device (The outer arc) is inserted into the locking system and the coupling is released. The vertical axis of the iron is freely pushed into the groove. With a pivot point on top Until the longest part of the iron core Contact with the arc of the drag that is inserted into the entanglement The iron core will be rebounded by the pulling force of the The spring returns to the vertical fill position. Automatically Make the end of the set of the ear drag (The inner arc) will be polished to the original position (vertical) iron core acting as a pivot point and lock. Between the two cars
