Technical Field

[0001] The utility model relates to the technical field of steel strand anchor cable construction in slope engineering, in particular to an installation and conveying device for steel strand anchor cables. Background Art

[0002] At present, slope support engineering can be divided into slope surface support (to prevent surface rockfall) and deep support (to prevent overall slope sliding) according to the support purpose. The support technologies corresponding to the former are mainly: protective net technology, net spraying technology, stone fence technology, net box loading support technology, etc.; the support technologies corresponding to the latter are mainly: prestressed anchor cable technology, anti-slide pile technology, grouting reinforcement, etc.; Among them, in the slope reinforcement with prestressed anchor cable technology, manual digging, manual insertion of anchor cables, and pouring of concrete for reinforcement are often used; however, the anchor cable is generally 20 to 100 meters long. When installing the anchor cable manually, one person is required to insert the anchor cable inward at the hole mouth, and at least one person is required to carry the anchor cable to the hole; this installation method requires the cooperation of multiple people, and each time the anchor cable is inserted manually, the strength is small and different, and the anchor cable cannot be installed at a uniform speed. The installation is very laborious, the construction efficiency is low, and the degree of mechanization is low; if the anchor cable is inserted too fast, the anchor cable will bring people down, posing a safety hazard.

[0003] In view of this, the designer has conducted in-depth research and actively conducted improved trials to develop and design this case in view of the many deficiencies and inconveniences caused by the imperfect design of the above-mentioned steel strand anchor cable installation structure.

[0005] In order to achieve the above purpose, the solution of the utility model is:

[0006] A device for installing and conveying a steel strand anchor cable comprises two parallel vertically arranged fixed bases, two lower rollers arranged between the two fixed bases and distributed in parallel in the horizontal direction, two upper rollers slidably arranged between the two fixed bases and distributed in parallel in the horizontal direction, a first driving mechanism for driving the lower rollers to rotate, and a second driving mechanism for driving the upper rollers to rotate; the two lower rollers and the two upper rollers correspond one to one in the vertical direction, one end of the steel strand anchor cable passes through the gap between the lower rollers and the upper rollers, and the first driving mechanism and the second driving mechanism respectively drive the lower rollers and the upper rollers to roll and drive the steel strand anchor cable to be conveyed.

[0007] Each of the fixed bases has three guide pillars arranged at equal intervals and a cover plate laterally locked on the top of the three guide pillars; sliding supports are provided at both ends of each of the upper rollers, vertical slide grooves are provided on both sides of the sliding supports, and the two vertical slide grooves on the same sliding support are slidably arranged on two adjacent guide pillars; two countersunk holes are symmetrically arranged on the top surface of each sliding support, and a through hole is arranged on the cover plate corresponding to each countersunk hole on the sliding support on the same side; one end of the bolt passes through the through hole and is locked in the countersunk hole, a spring is sleeved on the bolt, and the top end of the spring abuts against the bottom surface of the cover plate, and the bottom end of the spring abuts against the top surface of the sliding support.

[0008] The rolling direction of the lower roller is consistent with the advancing direction of the steel strand anchor cable, and the rolling direction of the upper roller is opposite to the rolling direction of the lower roller.

[0009] The outer annular walls of the upper roller and the lower roller are concave from both ends toward the middle arc to form an arc-shaped pressing roller surface.

[0010] The outer annular walls of the upper roller and the lower roller are wrapped with a rubber layer.

[0011] The first driving mechanism is a hydraulic motor arranged on one side of the lower roller, and the second driving mechanism is a hydraulic motor arranged on one side of the upper roller.

[0012] The fixed base is provided with two guide plates at one end where the steel strand anchor cable enters, and the guide plates have inclined portions that gradually expand outwards from the end where the steel strand anchor cable enters.

[0013] After adopting the above structure, the installation and conveying device of the steel strand anchor cable of the utility model first passes one end of the steel strand anchor cable through the gap between the lower roller and the upper roller when conveying the steel strand anchor cable, and then the first driving mechanism and the second driving mechanism respectively drive the lower roller and the upper roller to roll and convey the steel strand anchor cable to the hole in the slope; the installation and conveying mechanical device of the utility model replaces the manual installation of the steel strand anchor cable, has a high degree of mechanization, fast construction speed, and saves time and labor; and can convey the steel strand anchor cable at a uniform speed, with high safety; because the steel strand anchor cable is composed of multiple steel bars tied together The steel strand anchor cables are assembled together or through an assembly plate with holes, so the diameter at the bundling position or the assembly plate position is larger than the diameter at other positions. In order to avoid the bundling position or the assembly plate position being stuck on the installation and conveying device, the upper roller can be slidably set on the fixed base; during the transportation of the steel strand anchor cable, when the installation and conveying device encounters the bundling position or the assembly plate, the upper roller automatically slides upward to provide space to make way, and the steel strand anchor cable is transported more smoothly; and the distance between the upper roller and the lower roller can be flexibly adjusted, so that steel strand anchor cables of different diameters can be transported, and the adaptability is wider.
