Problems solved by technology
This kind of operation method that needs to use the winch and the truck crane to cooperate with each other on the beam surface is easy to damage the outer protective cover of the stay cable, and the alignment time of the stay cable is long; at the same time, a jack needs to be installed at the bottom of the beam for tensioning operation. The process is complicated, the working space under the beam is narrow, and the operation is difficult

Embodiment Construction
[0026] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.
[0027] see figure 1 As shown, the embodiment of the present invention provides a cable-hanging device at the beam end of a stay cable, comprising: a chassis 1; a push sleeve 2, which is sleeved outside the stay cable 3; a push frame 4. The push frame 4 includes a pair of vertical trusses 41 and a pair of guide rails 42. The two vertical trusses 41 are respectively arranged on both sides of the push sleeve 2. One end of the two vertical trusses 41 is connected to the chassis 1, and the other end is connected by a The vertical jack 43 is connected to the chassis 1; the inclination angle of the push sleeve 2 can be adjusted by adjusting the raised height of the vertical jack 43 until the inclination angle of the push sleeve 2 reaches the requirement of hanging the cable. see figure 2 As shown, two guide rails 42 are respectively arranged on tw...

The invention discloses stay cable beam end hanging equipment and relates to the field of cable-stayed bridge cable hanging construction. The stay cable beam end hanging equipment comprises a chassis, an ejecting sleeve arranged on a stay cable in a sleeving mode, an ejecting frame and two longitudinal moving devices. The ejecting frame comprises a pair of vertical trusses and a pair of guide rails, wherein the two vertical trusses are arranged on the two sides of the ejecting sleeve respectively, one ends of the two vertical trusses are connected with the chassis, and the other ends of the vertical trusses are connected with the chassis through vertical jacks respectively. The two guide rails are arranged on the vertical trusses respectively and provided with a plurality of pin holes. The two longitudinal moving devices are arranged on the two guide rails respectively, and each longitudinal moving device comprises two counterforce bases and a longitudinal jack, wherein one end of the longitudinal jack is connected with the ejecting sleeve through one counterforce base, the other end of the longitudinal jack is connected with the other counterforce base, and each counterforce base is selectively fixed to any pin hole. By means of the stay cable beam end hanging equipment, accurate alignment and quick hanging of a beam end stay cable can be achieved on the face of a main beam, operation is simple, and damage to a stay cable protection sleeve can be avoided.
Description
technical field [0001] The invention relates to the field of cable-stayed bridge cable-hanging construction, in particular to a cable-stayed cable beam-end hanging device. Background technique [0002] The traditional construction scheme of stay cable hanging at the beam end is: use a truck crane to adjust the vertical inclination of the stay cable on the bridge surface, set a traction winch on the beam surface to pull the anchor head of the stay cable into the cableway pipe through the Huff clamp, Then install the jack under the beam surface to carry out the soft and hard traction operation of the stay cable, and complete the cable hanging operation after the anchor head of the stay cable at the beam end moves to the designed position. This kind of operation method that needs to use the winch and the truck crane to cooperate with each other on the beam surface is easy to damage the outer protective cover of the stay cable, and the alignment time of the stay cable is long; a...
