Detailed Description
The present invention will be further explained with reference to the accompanying drawings.
As shown in fig. 1 to 3, a net rack ball hook comprises a central stay 11, a hoop 12 and a wire rope 13.
The center stay 11 is provided with a connecting hole, and the connecting hole is arranged along the length direction of the center stay 11 and is coaxial with the center stay 11. The hoop 12 is sleeved on the net rack ball, one end of the steel wire rope 13 is connected with the hoop 12, and the other end of the steel wire rope penetrates through the connecting hole and then is connected with an anchorage device. The anchorage device is provided with a lifting hole. The anchorage is located at the upper end of the centre strut 11.
A supporting plate 21 is fixed at the upper end of the central stay 11, a plurality of steel pipe stays 22 are hinged on the supporting plate 21, and the number of the steel pipe stays 22 is larger than or equal to that of the web members. The web members, the steel pipe stay 22 and the center stay 11 form a triangular structure therebetween. The steel pipe stay 22 is internally provided with a white coir rope 23 in a penetrating way, and the white coir rope 23 is sleeved at the middle part of the web member. The steel tube brace 22 is provided with a tensioning mechanism 3 for tensioning the white coir rope 23.
The tensioning mechanism 3 includes a mounting hole, a fixing tube 31, a supporting seat 32, a rotary sleeve 33 and a spring plate 34. The mounting hole is opened on the outer wall of steel pipe vaulting pole 22 and communicates with the inner wall of steel pipe vaulting pole 22. The fixing tube 31 is fixedly connected with both ends of the white coir rope 23 and extends out of the mounting hole. The support seat 32 is fixed on the outer wall of the steel pipe stay 22, and the rotary sleeve 33 is rotatably connected to the support seat 32 and is in threaded connection with the fixed pipe 31.
A plurality of positioning grooves 4 are formed in the outer wall of the rotating sleeve 33, and the positioning grooves 4 are uniformly distributed along the axis of the rotating sleeve 33. The elastic sheet 34 is disposed obliquely, and one end of the elastic sheet is disposed on the supporting seat 32, and the other end of the elastic sheet is embedded in the positioning groove 4. So that a one-way structure is formed between the spring piece 34 and the positioning slot 4.
A rotation hole 5 is formed in the support base 32, and a connection rod 51 is rotatably connected to the rotation hole 5. One end of the elastic sheet 34 is fixed on the connecting rod 51; the support base 32 is connected to the connecting rod 51 through the limit mechanism 6.
The limiting mechanism 6 comprises a limiting concave hole 61, an elastic piece 62, a placing hole 63 and a sliding column 64. The limiting concave hole 61 is formed in the inner wall of the rotating hole 5; a placement hole 63 is opened on the outer wall of the connecting rod 51, and the elastic member 62 and the sliding column 64 are placed in the placement hole 63. The sliding column 64 is pressed against the inner wall of the limiting concave hole 61 through the elastic force of the elastic piece 62.
An assistant rod 7 is fixed on the outer wall of the connecting rod 51, and the assistant rod 7 and the connecting rod 51 are arranged in an L shape.
In conclusion, when the hoop 12 is used, the hoop is sleeved on the net rack ball, and the steel wire rope 13 penetrates through the connecting hole and then is fixedly connected with the anchorage device. Then the white coir rope 23 is sleeved in the middle of the web member, and the two ends of the white coir rope 23 are fixed on the fixing tube 31. The rotating sleeve 33 is rotated in the forward direction, and the fixed sleeve is moved in the direction away from the steel pipe stay 22 along the mounting hole, so that the tensile force in the direction approaching the center stay 11 is applied to the web members by the white coir rope 23, and the bending moment is resisted by the tensile force. Thereby avoiding damage to the high-strength bolt.
After the lifting is carried to a destination, the assisting rod 7 drives the connecting rod 51 to rotate, the elastic sheet 34 is moved out from the positioning groove 4, the rotating sleeve 33 rotates reversely, the white coir rope 23 can be separated from the web member, and finally the steel wire rope 13 is separated from the hoop 12, so that the operation is simple and convenient.
