[0026] Example
[0027] like Figure 1-5 As shown, the tank truck open-air unloading safety hook assembly of the embodiment includes a safety rope 1 that passes through and is arranged above a plurality of unloading positions, and connectors 2 are fixedly arranged at both ends of the safety rope 1. One side of the unloading position is a cement pier 3, and the other side of the unloading position is fixedly arranged with a column 4. The connectors 2 located on both sides of the safety rope 1 are fixedly connected to the cement pier 3 and the column 4 respectively; the safety rope 1 is provided with a hook 5 that is convenient for hooking the safety belt hook.
[0028] With such a design, a safety rope 1 is arranged above the multiple unloading positions along the width direction, and the two ends of the safety rope 1 are fixed by using the concrete piers 3 on the existing site and additional columns 4 on the open space; after the driver puts on the safety belt, the hook of the safety belt can be hooked into the through hole of the hook 5, thereby ensuring the safety of the driver's high-altitude operations.
[0029] Furthermore, a plurality of safety ropes 1 are provided along the length direction of a single unloading space.
[0030] With such a design, the driver can select the corresponding safety rope 1 for hooking according to the parking spaces for different drivers to reverse into or the opening positions of the manhole covers of different tank trucks.
[0031] Specifically, at least two upright posts 4 are provided along the length direction of a single unloading position, and a cross bar 6 connected between a plurality of upright posts 4 is further provided, and the connecting member 2 is fixedly connected to the cross bar 6 .
[0032] Through such a design, the purpose of fixing multiple safety ropes 1 is achieved.
[0033] Furthermore, there is a height difference between the height of the cement pier 3 and the height of the cross bar 6 .
[0034] With such a design, the safety rope 1 is tilted, and a larger and taller tank truck can be docked on the higher side of the safety rope 1; a smaller and shorter tank truck can be docked on the lower side of the safety rope 1, which has a wide range of applications.
[0035] Specifically, a blocking piece 7 is fixedly provided on the safety rope 1 , and a plurality of blocking pieces 7 are provided along the extending direction of the safety rope 1 .
[0036] Through such a design, the position of the hooking member 5 can be limited to prevent the driver from sliding down along the inclined direction of the safety rope 1 when he accidentally falls from the top of the tank truck.
[0037] Specifically, the hook member 5 is movably connected to the safety rope 1, and the hook member 5 has three working positions. In the first working position, the hook member 5 moves between two adjacent blocking pieces 7; in the second working position, the hook member 5 and the blocking piece 7 are arranged against each other; in the third working position, the hook member 5 is sleeved outside the blocking piece 7, and the blocking piece 7 is passed through the hook member 5.
[0038] This design ensures the flexibility of the hook 5 and prevents the hook 5 from sliding down when the driver accidentally falls. It also ensures that the hook 5 is not blocked by the blocking piece 7 when the driver moves on the top of the tank truck.
[0039] Specifically, the connecting member 2 includes a connecting rod 21 fixedly connected to the cross bar 6 or the concrete pier 3, a through rod 22 for sleeved with the safety rope 1, and a limiting rod 23 for preventing the safety rope 1 from falling off. The connecting rod 21, the through rod 22 and the limiting rod 23 are arranged in sequence, and the diameters of the connecting rod 21 and the limiting rod 23 are greater than the diameter of the through rod 22.
[0040] Through such a design, the firmness of the fixed connection between the safety rope 1 and the connecting piece 2 is ensured.
[0041] Furthermore, the limiting rod 23 is provided with a curved surface 24 that contacts the safety rope 1 .
[0042] This design can prevent the safety rope 1 from being worn at right angles by the limiting rod 23 , thereby extending the service life of the safety rope 1 .
[0043] Specifically, the safety rope 1 is provided with a ring 11 which is sleeved outside the penetration rod 22 .
[0044] This design facilitates the connection between the safety rope 1 and the penetration rod 22 .
[0045] Furthermore, it also includes a supporting inclined column 8 for supporting the column 4 , one end of the supporting inclined column 8 is fixedly connected to the ground, and the other end of the supporting inclined column 8 is fixedly connected to the side wall of the column 4 .
[0046] Such a design ensures that the upright column 4 is firmly fixed and prevents the upright column 4 from tipping over.
[0047] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
