Abstract
The utility model belongs to the technical field of bridge building, in particular to a movable rock anchor of a cable crane. An upper prestressing anchor cable and a lower prestressing anchor cable (1) are arranged in a concrete anchorage pier (2); two lower distribution beams (4) are installed on the concrete anchorage pier (2) cushioned by a steel cushion beam (3); chutes (5) are arranged on the lower distribution beams (4); and a movable anchor beam (6) is installed on the chute (5) and is provided with a cable anchoring pulley (8) and a fastening device (7). The movable rock anchor of the cable crane has clear stressed system and simple structure, can obtain better guarantee for the external environmental safety of the construction by application thereof, reduce the mutual construction interference, save a construction period and lower the cost.
Description
Technical field
The utility model belongs to the bridging technical field, is specifically related to the removable rock anchor of a kind of cable crane.
Background technology
At present, existing cable crane anchorage adopts gravity type boat davit cement concrete anchorage more at the steep cliff place, in order to bear the pulling force of track cable, its blow out the excavation work capacity very huge, the work of massif excavation directly influences the construction of its below science of bridge building, not only the construction period is restricted, and has outstanding safety problem.
Summary of the invention
The purpose of this utility model is that a kind of light-duty anchorage will be provided, it not only can substitute gravity type boat davit cement concrete anchorage, and help that whole anchorage system is stressed, anchorage is simple in structure, can also side travel satisfy the demand of cable crane track cable diverse location.
The removable rock anchor of a kind of cable crane of the utility model is located in the cement concrete anchor pier at twice prestress anchorage cable up and down, and distribution beam is installed on the cement concrete anchor pier that is lined with the steel bearing beam under the twice; Chute is set on the distribution beam under the twice, and removable anchor beam is installed on the chute; Removable anchor beam is provided with cable anchoring pulley and securing device.
The removable rock anchor of a kind of cable crane of the utility model, securing device are that 6 groups of detouchable bolts are formed.
The removable rock anchor of the utility model cable crane system is stressed clear and definite, simple in structure, and its utilization can make construction external environment condition safety obtain better guarantee, reduces mutual construction and disturbs, and saves the duration, the reduction expense.
The removable rock anchor of the utility model cable crane, be to utilize the prestress anchorage cable anchoring system to make down distribution beam and massif be combined into an organic whole, when the prestress anchorage cable prestress value greater than removable anchor beam, down after the cable crane maximum transmitted of distribution beam during anchor force, between anchorage and the massif relative displacement will not take place in the cable crane operation process, removable anchor beam can drive track cable and move to assigned address along slideway when unloaded.The prestressed anchor cable system is distribution beam, steel bearing beam and massif anchoring under the twice, and is middle by the power transmission of cement concrete anchor pier, and following distribution beam is in addition as the slideway of removable anchor beam.Be connected with following distribution beam by securing device during removable anchor beam mode of operation, be connected with following distribution beam by chute during traversing state; Chute and removable anchor beam are structure as a whole, and toss about cable anchoring pulley is set is connected with the cable crane track cable.
Description of drawings
Accompanying drawing 1: removable rock anchor half front view of cable crane;
Accompanying drawing 2: the removable rock anchor of cable crane left view;
Accompanying drawing 3: half front view that adopts the removable rock anchor construction of cable crane.
In the accompanying drawing, 1-prestress anchorage cable, 2-cement concrete anchor pier, 3-steel bearing beam, distribution beam under the 4-, 5-chute, the removable anchor beam of 6-, 7-securing device, 8-cable anchoring pulley.
The specific embodiment
Embodiment: the prestress anchorage cable of twice up and down 1 of the removable rock anchor of the utility model cable crane is located in the cement concrete anchor pier 2, and distribution beam 4 is installed on the cement concrete anchor pier 2 that is lined with steel bearing beam 3 under the twice; Chute 5 is set on the distribution beam 4 under the twice, and removable anchor beam 6 is installed on the chute 5; Removable anchor beam 6 is provided with cable anchoring pulley 8 and securing device 7.Securing device 7 is that 6 groups of detouchable bolts are formed.
The work progress of the removable rock anchor of the utility model cable crane is as follows: behind the accurate unwrapping wire of design attitude, carry out up and down twice prestress anchorage cable 1 construction, treat that cement concrete anchor pier 2 reaches certain intensity and carries out prestress anchorage cable 1 stretch-draw after with distribution beam 4 installations under steel bearing beam 3, the twice; The removable anchor beam 6 of processing and fabricating is provided with chute 5, securing device 7, cable anchoring pulley 8 on it, place down in distribution beam 4 slideways from side direction after finishing; After the cable crane track cable was connected to cable anchoring pulley 8, utilizing up and down, securing device 7 entered lift heavy work operations state with following distribution beam after 4 firm connections with removable anchor beam 6; When needing to change the position after operation finishes, unclamp securing device 7, removable anchor beam 6 drives track cable and is drawn to assigned address along slideway (following distribution beam 4) with chain block or winch.
Claims (2)
1. the removable rock anchor of cable crane is characterized in that twice prestress anchorage cable (1) is located in the cement concrete anchor pier (2) up and down, and distribution beam under the twice (4) is installed on the cement concrete anchor pier (2) that is lined with steel bearing beam (3); Chute (5) is set on the distribution beam under the twice (4), and removable anchor beam (6) is installed on the chute (5); Removable anchor beam (6) is provided with cable anchoring pulley (8) and securing device (7).
