Technical Field

The invention relates to the field of cable structure design, in particular to an anti-sliding brake device which is formed by a high-strength bolt cover plate and is independent of a cable clamp.

Background

In a tension structure system such as a cable structure, a difference in cable force between both ends of a cable and a cable clamp, that is, an unbalanced force is a widely existing load acting form. In order to ensure the structural safety, the cable body should not slide at the cable clamp position, and the cable clamp needs to have enough bearing force resisting unbalanced force to prevent the cable body from sliding at the cable clamp position. The unbalanced force of the resisting cable is usually divided into two types, one is that the cable body is disconnected at the cable clamp position, the unbalanced force is directly transmitted to the cable clamp through the anchorage devices at the cable body ends at two sides, and thus the possibility of cable body slippage is avoided. The other method is that a cover plate with high-strength bolts is arranged on a cableway of the cable clamp, pressure perpendicular to the cable body is applied by pre-tightening the high-strength bolts, and the sliding action of the cable body generated by unbalanced force is resisted through the friction force generated by the pressure.

As shown in fig. 1, the cover plate used for applying the pre-tightening force on the conventional cable clamp is arranged on the cable clamp cableway, and in order to generate the anti-slip capability to resist the unbalanced force, a certain number of high-strength bolts are required to generate sufficient pre-tightening force, which requires a wide enough cover plate to arrange a corresponding number of bolts. Because the apron is located the cableway top of cable clamp, when unbalanced force is great, the cable clamp size just need constantly increase in order to adapt to more high-strength bolt and the enlargement of apron size. This results in a clip of ever increasing size and weight, which in turn results in a reduction in structural economy.

In order to solve the above problems, the applicant of the present invention proposes an anti-sliding brake device, which is independent from the cable clamp body and is composed of a pair of cover plates independent from the cable clamp and high-strength bolts thereon, as shown in fig. 2, the brake is mounted on the cable body outside the cable clamp, and the cable body is clamped by the pair of cover plates and the high-strength bolts on the cover plates and provides pressure to generate sufficient anti-sliding bearing force to resist the cable body sliding caused by unbalanced force. The brake is arranged on the outer side of the cable clamp along the direction of the cable body, is connected with the cable clamp through pre-jacking the cable clamp or mechanically, bears unbalanced force, prevents the cable body from sliding, and transmits the unbalanced force to the cable clamp. Because the brake only consists of a pair of bolt cover plates, the anti-sliding bearing capacity of the node can be effectively improved under the condition that the size of the cable clamp body is not additionally increased. After the brake is adopted, the weight of the cable clamp can be effectively controlled, and the structural economy is improved. Because the brake independently exists outside the cable clamp, when the unbalanced force is larger than the anti-sliding capacity of one group of brakes, a plurality of brakes can be connected in series, and the anti-sliding bearing capacity is improved.

The following detailed description of embodiments of the invention refers to the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present invention, are given by way of illustration and explanation only, not limitation.

Referring to fig. 2, the present embodiment provides an anti-slip brake device independent of a cable clamp, including one or more sets of brakes, where the brakes include two anti-slip brake cover plates 4, and the two anti-slip brake cover plates 4 clamp the rear two sides of a cable body 2 in a cableway 1 of a cable clamp 3 and are fastened by high-strength bolts; when the anti-sliding brake device is a group of brakes, the brakes are arranged on the outer sides of the cable clamps along the direction of the cable body; when the anti-sliding brake device is a plurality of groups of brakes, one brake is arranged on the outer side of the cable clamp along the direction of the cable body, and the other brakes are sequentially attached to and connected in series along the direction of the cable body, so that the anti-sliding bearing capacity is effectively improved (the structure is shown in fig. 4).

As shown in fig. 3, preferably, one end of the brake adjacent to the cable clamp abuts against the outer side of the cable clamp along the direction of the cable body. The friction force generated by the anti-slip brake cover plate 4 under the pretightening force of the high-strength bolt 5 resists the slip of the cable body under the unbalanced force F. When an unbalanced force F in the direction shown in fig. 3 exists, the unbalanced force F acts on the anti-slip brake cover plate 4, and the pair of brake cover plates ensure that the cable body does not slip under the action of friction force generated by pretightening force. The end faces of the cover plates are in dead jacking with the cable clamp under the action of unbalanced force, and then the unbalanced force is transmitted to the cable clamp body and transmitted to the structure.

As shown in fig. 5, preferably, one end of the brake adjacent to the cable clamp is fixedly connected to the cable clamp 3 through an unbalanced force transmitting bolt 6, and at this time, the anti-sliding brake cover plate of the brake adjacent to the cable clamp 3 and the cable clamp are both provided with connecting lug plates for the unbalanced force transmitting bolt to pass through. In the event of possible unbalanced forces in both directions as shown in fig. 5, the brakes can either be arranged symmetrically at both ends of the clamp in fig. 3 or, according to the configuration of fig. 5, the unbalanced force F1 or the unbalanced force F2 can be transmitted to the clamp by means of the transmitting unbalanced force bolt 6.
