Description

Technical Field

[0001] The utility model belongs to the technical field of electric power engineering construction, and more particularly to the technical field of auxiliary construction for transporting construction materials in transmission line construction of electric power engineering construction, and specifically relates to a construction cableway for transmission lines. Background Art

[0002] In the construction of transmission lines, due to restrictions such as the environment and geography, it is often impossible to transport materials by building construction access roads. Moreover, because the manual transportation distance is long and pack animals cannot be used, it is often necessary to transport construction materials by erecting a cableway.

[0003] Conventional reciprocating cableways require professional installation teams for installation and operation, and usually require clearing the path of the cableway. With the improvement of environmental protection requirements, in the existing transmission line erection paths and cableway construction paths, forest areas under protection often do not allow tree felling, which brings construction difficulties to cableway construction. Summary of the Invention

[0004] The utility model discloses a construction cableway. The purpose of the utility model is to provide a material transportation construction cableway that can be erected and operated in areas where tree felling is not allowed, such as protected forest areas.

[0005] The utility model is realized by adopting the following technical solutions:

[0010] Two sets of anchoring systems are respectively arranged at the high and low ends of the cableway transportation path; each set includes three levels of anchoring mechanisms, and each level of anchoring mechanism includes an anchoring cross bar horizontally arranged along the transportation path; the first-level anchoring cross bar is deeply buried and anchored in an underground anchoring pit, and is connected and fixed to the second-level anchoring cross bar through two parallel steel wire ropes; the second-level anchoring cross bar is arranged on the ground, and both ends of the load-bearing cable are respectively connected and fixed to the second-level anchoring cross bars at the high and low ends. The second-level anchoring cross bar is also connected and fixed to the third-level anchoring cross bar through two parallel steel wire ropes; each third-level anchoring cross bar is respectively connected to two steering pulleys arranged at the high or low end of the traction system.

[0011] Furthermore, the bracket is composed of two brackets vertically fixed to the ground and a cross bar horizontally connected between the two brackets; the load-bearing cable support and the traction cable support are suspended on the cross bar of the bracket.

[0021] The present utility model will be further described below in conjunction with the detailed implementation manners. The detailed implementation manners are further explanations of the principle of the present utility model and do not limit the present utility model in any way. The technologies identical or similar to the present utility model do not exceed the protection scope of the present utility model.

[0022] In conjunction with the accompanying drawings.

[0023] As shown in the figure, the construction cableway of the present utility model includes a suspension support system, a traction system, a load basket, and an anchoring system.

[0024] The suspension support system includes a load-bearing cable 1, a load-bearing cable support 2, and a support assembly 5. The load-bearing cable 1 is fixed to the support assembly 5 through the load-bearing cable support 2, and the load borne is transmitted to the ground through the support assembly 5.

[0025] The traction system includes a winch 10, a towing cable 4, a towing cable support 3, and a turning pulley 9. The towing cable 4 passes through the towing cable support 3 and the turning pulley 9, and the winch 10 is used as the power to drive the towing cable 4 to move cyclically, and drives the load basket 8 fixedly connected to the towing rope 4 to move back and forth cyclically, so as to realize the transportation of materials to high places; the empty load basket 8 can also be transported back to the low-place storage yard through the towing rope 4 for reloading. When transporting goods upward, the load basket 8 is hung on the load-bearing cable 1 through the pulley of the walker 7; the walker 7 is fixed to the towing cable 4 through a clamp and is driven by the towing cable 4.

[0026] Both the load-bearing cable 1 and the towing rope 4 are high-strength carbon steel wire ropes. The load-bearing cable support 2 is made of carbon steel and can fix the load-bearing cable 1 and enable the pulley of the walker 7 to pass smoothly. The towing cable support 3 is a pulley fixed on a carbon steel bracket, which can limit the towing rope 4 to slide back and forth on the pulley without coming off and can pass through the walker 7 smoothly.

[0027] Such as Figures 1 to 4 , a cableway system for construction transportation in mountainous areas in this embodiment includes a suspension support system, a traction system, a load basket, and an anchoring system.

[0028] The suspension support system includes a load-bearing cable 1, a load-bearing cable support 2, and a bracket assembly 5. The load-bearing cable 1 is fixed to the load-bearing cable support 2, and the load-bearing cable support 2 is fixed to the bracket assembly 5 by wire binding. The main weight of the transported goods is transmitted from the load-bearing cable 1 to the ground through the suspension support system.

[0029] The traction system includes a traction cable 4, a traction cable support 3, a steering pulley 9, and a winch 10. The traction rope 4 is limited by the pulleys of the traction cable support 3, and is steered through 4 steering pulleys 9 at the beginning and end to form a closed loop and be connected end to end. The winch 10 provides power to achieve reciprocating circulation. The traction cable 4 transmits the traction force required for transporting goods and bears the self-weight of the relatively light return empty basket 8. The return load basket 8 can be suspended and transported by the downward return traction cable 4.

[0030] The load basket 8 is made of an iron bucket and contains goods to be transported such as sand and cement. When transporting long items such as tower materials, the tower materials can be bundled, and both ends are tied to the bottom hooks of the front and rear walkers 7 by steel wires. The load basket 8 is hung on the walker 7. The top pulley of the walker 7 is supported by the load-bearing cable 1, transmitting the weight of the goods to the suspension support system. The walker 7 is detachably connected to the traction cable 4 and is traction-driven to move following the traction of the traction system.

[0031] The ground anchor of the anchoring system is made of steel wire ropes and logs. After excavating the ground anchoring pit on-site, the first log is placed, and two steel wire ropes are tied to both ends of the log and then buried deeply. The other ends of the two steel wire ropes are anchored to both ends of the second log, and at the same time, the terminal of the load-bearing cable 1 is anchored to the second log. The two steering pulleys 9 are fixed to the third log by steel brackets and wire binding. The third log is connected to the second log by two steel wire ropes, ensuring that the loads transmitted from the traction system and the load-bearing support system are transmitted into the ground through the ground anchor.

[0032] After completing the installation and commissioning of the transport cableway, keep the winch 10 in the braking gear, and then the load basket 8 can be loaded or unloaded. After the loading and unloading are completed, when the winch 10 is in the forward rotation position, it drives the traction system to circulate forward, that is, the goods are transported upward and the empty vehicle returns. When it is necessary to adjust the position of the load basket and the loading and unloading position, fine adjustment can be achieved by reversing the winch 10.
