By arranging the threaded rod 4 into two rod sections (a first screw rod section 4a and a second screw rod section 4 b) with different pitches, when the threaded rod 4 is rotated, the second screw rod section 4b is screwed into the fixing nut 8 and always screwed into the middle-small hole 811, and the distance of the second screw rod section 4b screwed into the fixing nut 8 is short because the pitch of the second screw rod section 4b is small; at the same time, the pitch of the first screw rod section 4a is large, and the upward moving distance of the movable nut 5 on the first screw rod section 4a is large, so that the movable nut 5 moves upward relative to the fixed nut 8, the compression of the arc pressing block 9 and the tensioning of the rope 3 are realized, and conversely, the loosening of the arc pressing block 9 and the rope 3 is realized. The design is simple and quick to operate, firm and reliable in fixation, axial positioning can be carried out on the threaded rod 4, coaxiality in the rotating process of the threaded rod 4 is guaranteed, deflection in the rotating process is prevented, clamping and fixing can be carried out rapidly, and leakage environmental pollution and life safety accidents during unloading are avoided.

As shown in fig. 2 and 3, as a preferable mode of the present utility model, at least two arc pressing pieces 9 are provided at a fixed distance apart, and a notch 91 for passing the rope 3 is formed between the hose 1, the arc pressing pieces 9 and the mounting piece 81. In the utility model, the number of the arc pressing blocks 9 is two, and only one rope 3 correspondingly passes through the notch 91, and the rope 3 is directly wound on the outer wall of the hose 1 to realize clamping. When the number of the arc pressing blocks 9 is three, two notches 91 are formed, two ropes 3 are correspondingly arranged, and the two ropes 3 are fixed on the same movable nut 5. The recursion is that n arc pressing blocks 9 are provided, and n-1 ropes 3 are provided, so that the clamping force of the clamping device is greatly increased.

As shown in fig. 4, as another preferred embodiment of the present utility model, a fixing groove 92 for receiving the rope 3 is formed at the connection node of the circular arc pressing block 9 and the mounting block 81. In this case, when the rope 3 is wound around the outer wall of the hose 1, the rope 3 is not passed through the notch 91 but is wound around the fixing groove 92, and in this case, when the rope 3 is pulled, the arc pressing block 9 and the hose 1 are stably pulled by the rope 3, so that the fixing strength is further enhanced.

Further, the inner diameter of the arc pressing block 9 is equal to the outer diameter of the hose 1, so that the surface of the hose 1 can be completely attached to the surface, and more effective fixation is realized.

Further, the rope 3 is a steel wire rope, and a plastic coating layer is sleeved on the outer wall of the steel wire rope, so that the effects of wear resistance, skid resistance and no damage to the hose 1 are achieved.

Further, a handle 6 is fixed at the upper end of the first screw section 4a, so that the screw rod 4 can be rotated in a labor-saving manner.

The using method of the fastening device comprises the following steps:

when the dangerous chemical automobile tank car is unloaded, firstly, the PVC steel wire hose 1 is inserted into the outer side of the automobile tank car unloading outlet pipe 2, and a certain insertion depth is kept; the clamping device is then placed over the junction of the PVC wire hose 1 and the car hopper car discharge outlet pipe 2.

The rope 3 is then wound at least one and a half times around the PVC wire hose 1, and the movable nut 5 is adjusted so as to be rotated up and down on the first screw section 4a until a suitable position is reached, so that the other end of the rope 3 can just be hung on the hook head 52. At this time, the positions of the integral rope 3 and the movable nut 5 have been adjusted, and the rope 3 has a certain tightness (tightness of manually winding the hose 1, hanging on the hook head 52).

After the movable rope of the rope 3 is buckled and hung on the hook head 52, the steel handle 6 rotates the threaded rod 4 clockwise (the first screw rod section 4a and the second screw rod section 4b synchronously rotate), and the movable nut 5 is held by one hand to avoid the rotary motion. At this time, the second screw rod section 4b is screwed into the hose 1 with respect to the fixed nut 8, and since the screw pitch of the second screw rod section 4b is smaller than the screw pitch of the first screw rod section 4a, the movable nut 5 moves toward the handle 6 with respect to the fixed nut 8 (i.e., the unscrewing distance of the movable nut 5 is greater than the screwing distance of the threaded rod 4), and at this time, the movable nut 5 withdraws from the direction away from the circular arc pressing block 9 with respect to the fixed nut 8, thereby tightening the rope 3, the circular arc pressing block 9 and the rope 1 respectively compress and tighten the PVC steel wire hose 1 in a multi-point and multi-section manner, and checking the tightening condition of the PVC steel wire hose 1, dynamic adjustment can be performed, and the unloading operation is performed after being firm.

After the dangerous chemicals of the car tank wagon are unloaded, the surplus acid in the PVC steel wire hose 1 is returned, the threaded rod 4 is rotated anticlockwise through the steel handle 6, at the moment, the arc pressing block 9 and the plastic coated steel wire rope are loosened, the movable rope buckle of the plastic coated steel wire rope is taken down from the hook head 52, the winding of the rope 3 is loosened, the clamping device is taken down, the PVC steel wire hose 1 is pulled out, and the dangerous chemicals are unloaded safely.

According to the utility model, after the rope 3 is wound on the hose 1, the position of the movable nut 5 is adjusted, then the movable rope of the rope 3 is buckled and hung on the hook head 52, and then the rope 3 can be tensioned by rotating the threaded rod 4 to compress the arc pressing block 9, and the two ends of the rope 3 are not required to be mutually rotated and wound to realize the fastening, so that the problem that the rope 3 is mutually fastened and guided to the abrasion of the rope 3 is avoided, that is, the repeated use of the rope 3 can be realized, and the long-period use effect can be achieved.

Example 2

In a second embodiment of the utility model, another way of connecting the threaded rod 4 is proposed.

As shown in fig. 5, the hose clamping device comprises a rope 3, a threaded rod 4, a movable nut 5 and an arc pressing block 9, wherein the whole thread pitch of the threaded rod 4 is identical and is matched and connected with the movable nut 5, a limiting ring 41 is arranged at the bottom end of the threaded rod 4, and at least one limiting ring is arranged. The retainer ring 41 is disposed adjacent the central aperture 411 for rotational movement within the central aperture 411. The installation piece 81 upper end is fixed with briquetting 10, and the hole of briquetting 10 allows threaded rod 4 to pass, and the bottom of briquetting 10 covers partial centre bore 411 for briquetting 10 can carry out spacingly to spacing ring 41, prevents that threaded rod 4 from deviating from in the centre bore 411, spacing rotary motion in centre bore 411. In this way, the threaded rod 4 can be rotated, so that the movable nut 5 moves away from the pressing block 10, tensioning of the rope 3 is achieved, or the movable nut moves close to the pressing block 10, and loosening of the rope 3 is achieved.

In this embodiment, the configuration of the other components is the same as that of embodiment 1 except for the above-described configuration, and the details are not repeated here.

The above is only a preferred embodiment of the present utility model, and is not intended to limit the present utility model, but various modifications and variations can be made to the present utility model by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model should be included in the protection scope of the present utility model.
