Description

Technical Field

[0001] The invention relates to the field of electric power construction, in particular to a high-altitude fixed platform for a cable manufacturing cabin and a hoisting method thereof. Background Art

[0002] When making cable terminals and joints outdoors, the temperature should be controlled at 0℃-35℃, and the relative humidity should be 70% or below. The requirements for ambient temperature and humidity are high. Severe weather will seriously affect the construction progress and quality.

[0003] When making cable terminals on a tower, a scaffold is usually set up on the cable support of the tower as the skeleton of the production warehouse, and then a guard plate is installed outside the scaffold to form a warehouse chamber. Building the production warehouse requires high-altitude operations, and the construction convenience is very poor and the speed is slow. The production cycle of each joint is only one to two days, so the production warehouse needs to be frequently dismantled and rebuilt. This inefficient way of building the production warehouse has a great impact on the construction efficiency.

[0004] In addition, since there is only a horizontal bar between the cables as the construction foundation, the stability and safety of the scaffolding are poor. Summary of the invention

[0005] In order to solve the problems of low efficiency and poor safety in building a cable manufacturing cabin at high altitude, the present invention provides a cable manufacturing cabin high altitude fixed platform and a hoisting method thereof.

[0006] A high-altitude fixed platform for a cable manufacturing cabin comprises a cabin body and a rectangular bottom plate, wherein two first wedge-shaped strips are arranged in parallel in an "eight" shape, and the bottom plate further comprises two second wedge-shaped strips, wherein the inclined surfaces of the two second wedge-shaped strips are fitted with the inclined surfaces of the two first wedge-shaped strips to form a sliding pair; a horizontal comb-shaped top plate is fixed to the upper end of the second wedge-shaped strip, and the comb teeth of the top plates of the two second wedge-shaped strips are engaged with each other; It also includes a concrete counterweight block. A steel wire rope is respectively arranged on the four corners of the bottom plate. Each steel wire rope is provided with a group of tensioning mechanisms. The lower end of the steel wire rope is connected with the counterweight block. The steel wire rope can be tightened by the tensioning mechanism.

[0007] Each end of the first wedge-shaped strip is provided with a slide groove parallel to the inclined surface, and each end of the second wedge-shaped strip is fixed with an ear plate parallel to the end surface, a bolt is installed through the ear plate, a pulley is installed on the inner end of the bolt, and the pulley is placed in the slide groove at the same end.

[0008] Two groups of bolts and pulleys are arranged at intervals on each ear plate.

[0009] A pin hole is respectively opened on the four corners of the bottom plate, and four pin rods corresponding to the pin holes are installed at the bottom of the warehouse body. When the warehouse body is suspended, the pin rods are correspondingly inserted into the pin holes.

[0010] The tensioning mechanism includes a pneumatic cylinder vertically fixed on the lower surface of the base plate, a tensioning wheel is installed at the lower end of the pneumatic cylinder, and also includes a fixed pulley fixed on the small surface of the base plate. The upper end of the wire rope is fixed on the base plate, and the lower end of the wire rope passes around the tensioning wheel from the lower side and then passes around the fixed pulley from the upper side, then hangs down and is connected to the counterweight block.

[0011] A method for hoisting a high-altitude fixed platform of a cable manufacturing cabin comprises the following steps: Step 1: Install the second wedge-shaped bar, screw the bolts at both ends of the second wedge-shaped bar outward, so that the ear plates at both ends of the second wedge-shaped bar can be clamped on both ends of the first wedge-shaped bar, and the inclined surface of the second wedge-shaped bar is in contact with the inclined surface of the first wedge-shaped bar, and then screw the bolt inward, so that the pulley at the inner end of the bolt enters the slide groove, so that the second wedge-shaped bar cannot slip off; Step 2: Hang the counterweight block just below the crossbar to be installed, so that it is stably placed on the ground; Step 3: Lift the bottom plate above the crossbar, make the second wedge-shaped strip parallel to the crossbar, gradually lower the bottom plate so that the crossbar enters between the two second wedge-shaped strips, and the top plate of the second wedge-shaped strip presses on the crossbar. As the bottom plate continues to descend, the two second wedge-shaped blocks will move upward along the inclined surface until the inner sides of the two second wedge-shaped blocks clamp the crossbar, and the crane remains in position; Step 4: Tighten the four steel wire ropes and fix the lower ends of the steel wire ropes on the counterweight block, then start the pneumatic cylinder to push the tensioning wheel downward to fully tighten the steel wire ropes. At this time, the crane can be removed; Step 5: Lift the warehouse body above the bottom plate, and gradually lower the warehouse body so that the four pins at the bottom of the warehouse body are correspondingly inserted into the four pin holes on the bottom plate, and the warehouse is completed.

[0012] During installation, the present invention only needs to hang the bottom plate on the cross bar and tighten the wire rope, and then hang the warehouse body on the bottom plate. There is no need to build scaffolding on site or perform high-altitude operations, which can greatly shorten the construction time of the warehouse and effectively improve the construction efficiency. Moreover, the two second wedge blocks firmly clamp the two sides of the cross bar, and the center of gravity of the entire device is located below the cross bar, so that the entire device has higher stability and safety.

[0018] In conjunction with the accompanying drawings, a high-altitude fixed platform for a cable manufacturing cabin includes a warehouse body 1 and a rectangular bottom plate 2. The warehouse body 1 is an integrated prefabricated type. Two first wedge-shaped strips 3 are provided on the lower surface of the bottom plate 2. The two first wedge-shaped strips 3 are arranged in parallel in an "eight" shape. The bottom plate 2 also includes two second wedge-shaped strips 4. The inclined surfaces of the two second wedge-shaped strips 4 fit with the inclined surfaces of the two first wedge-shaped strips 3 to form a sliding pair; a horizontal comb-shaped top plate 5 is fixed to the upper end of the second wedge-shaped strip 4, and the comb teeth of the top plates 5 of the two second wedge-shaped strips 4 are engaged with each other; when the bottom plate 2 is hoisted onto the crossbar of the iron tower, the crossbar is placed between the two second wedge-shaped strips 4. After the top plate 5 of the second wedge-shaped strip 4 is pressed onto the crossbar, the two second wedge-shaped strips 4 will move upward synchronously along the inclined surface until the sides of the two second wedge-shaped strips 4 clamp the two sides of the crossbar, thereby achieving the fixation of the bottom plate 2 on the crossbar; It also includes a concrete counterweight 6, which is placed on the ground below the crossbar. A steel wire rope 7 is provided on each of the four corners of the base plate 2, and each steel wire rope 7 is provided with a group of tensioning mechanisms. After the base plate 2 is hung on the crossbar, the lower end of the steel wire rope 7 is connected to the counterweight 6, and the steel wire rope 7 can be tightened through the tensioning mechanism, so that the two second wedge-shaped strips 4 firmly clamp the crossbar and fix the base plate 2 firmly. Moreover, the counterweight 6 is hung below the base plate 2 so that the center of gravity of the base plate 2 is located below the crossbeam. Similar to the tumbler, the base plate 2 will not flip over, further ensuring the stability and safety of the base plate 2.

[0019] Each end of the first wedge-shaped strip 3 is provided with a slide groove 8 parallel to the inclined surface, and each end of the second wedge-shaped strip 4 is fixed with an ear plate 9 parallel to the end surface, and a bolt 10 is installed through the ear plate 9. A pulley 11 is installed at the inner end of the bolt 10, and the pulley 11 is placed in the slide groove 8 at the same end. The pulley 11 cooperates with the slide groove 8 to limit the second wedge-shaped strip 4 so that the second wedge-shaped strip 4 moves along the inclined surface.

[0020] Two groups of bolts 10 and pulleys 11 are arranged at intervals on each ear plate 9, which can prevent the second wedge bar 4 from deflecting and improve the stability of the second wedge bar 4 during movement.

[0021] A pin hole 12 is opened on each of the four corners of the bottom plate 2, and four pin rods 13 corresponding to the pin holes 12 are installed at the bottom of the warehouse body 1. When the warehouse body 1 is hung, the pin rods 13 are correspondingly inserted into the pin holes 12.

[0022] The tensioning mechanism includes a pneumatic cylinder 14 vertically fixed to the lower surface of the base plate 2, a tensioning wheel 15 is installed at the lower end of the pneumatic cylinder 14, and also includes a fixed pulley 16 fixed to the small surface of the base plate 2. The upper end of the wire rope 7 is fixed on the base plate 2. The lower end of the wire rope 7 passes around the tensioning wheel 15 from the lower side and then passes around the fixed pulley 16 from the upper side, then hangs down and is connected to the counterweight 6. The pneumatic cylinder 14 extends downward to tension the wire rope 7.

[0023] The hoisting method of the present invention is as follows: Step 1, install the second wedge strip 4, screw the bolts 10 at both ends of the second wedge strip 4 outward, so that the ear plates 9 at both ends of the second wedge strip 4 can be stuck on the two ends of the first wedge strip 3, and make the inclined surface of the second wedge strip 4 fit with the inclined surface of the first wedge strip 3, and then screw the bolt 10 inward, so that the pulley 11 at the inner end of the bolt 10 enters the slide groove 8, so that the second wedge strip 4 cannot slip off; after the installation is completed, push the second wedge strip 4 for inspection to ensure that the second wedge strip 4 and the first wedge strip 3 are effectively fitted without shaking, and can slide smoothly along the inclined surface; and pay attention to fine-tuning the position of the second wedge strip 4 in the length direction through the bolts 10 at both ends to ensure that the comb teeth of the top plates 5 of the two second wedge strips 4 do not interfere with each other and can bite smoothly; Step 2: Hang the counterweight 6 just below the crossbar to be installed, so that it is stably placed on the ground; Step 3: Ensure that the steel wire rope 7 is correctly passed around the tensioning wheel 15 and the fixed pulley 16, and the lower end of the steel wire hangs freely, and then the bottom plate 2 is lifted above the cross bar. During the lifting process, the second wedge bar 4 is located at the lower end of the slide groove 8 due to its own weight, so that the second wedge bar 4 is parallel to the cross bar, and the bottom plate 2 is gradually lowered so that the cross bar enters between the two second wedge bars 4. The top plate 5 of the second wedge bar 4 is pressed on the cross bar. As the bottom plate 2 continues to descend, the two second wedge blocks will move upward along the inclined surface until the inner side surfaces of the two second wedge blocks clamp the cross bar, and the crane remains in position; Step 4, tighten the four steel wire ropes 7 and fix the lower ends of the steel wire ropes 7 on the counterweight 6, then start the pneumatic cylinder 14 to push the tensioning wheel 15 downward to fully tighten the steel wire ropes 7, and then the crane can be withdrawn; after the steel wire ropes 7 are tightened, the two second wedge blocks will firmly clamp the crossbar and firmly fix the bottom plate 2, and the counterweight 6 is hung under the bottom plate 2, so that the center of gravity of the bottom plate 2 is located under the crossbeam, and similar to the tumbler, the bottom plate 2 will not flip over, further ensuring the stability and safety of the bottom plate 2; Step 5: Lift the warehouse body 1 above the bottom plate 2, and gradually lower the warehouse body 1 so that the four pins 13 at the bottom of the warehouse body 1 are correspondingly inserted into the four pin holes 12 on the bottom plate 2, and the warehouse is completed.

[0024] During installation, the present invention only needs to hang the bottom plate 2 on the cross bar and tighten the wire rope 7, and then hang the warehouse body 1 on the bottom plate 2. There is no need to build scaffolding on site or perform aerial work, which can greatly shorten the construction time of the warehouse and effectively improve the construction efficiency. Moreover, the two second wedge blocks firmly clamp the two sides of the cross bar, and the center of gravity of the entire device is located below the cross bar, so that the entire device has higher stability and safety.
