Description

TECHNICAL FIELD

[0001] The utility model belongs to the field of stringing construction, and particularly relates to an intelligent supporting device for connecting and fixing double pulleys. BACKGROUND

[0002] In the tension stringing construction process of a power transmission project, a stringing pulley needs to be hung on each phase cross arm of a tower, and a single pulley cannot bear the vertical load of a conductor in some tower positions, so that the construction safety cannot be guaranteed, and therefore double pulleys need to be arranged to reduce the load of a single pulley, so as to meet the requirements of construction safety and stringing quality.

[0003] However, the tool for fixing the double pulleys in the prior art is an angle steel, which has some defects.

[0004] 1. The length cannot be adjusted according to the needs, because the cross arm widths of different towers are different, so that the engineering and technical personnel appear angle steels of various lengths when lifting materials, which is not convenient for the unified management of tools and instruments and on-site construction.

[0005] 2. The angle steel is rigid in stress, and when the double pulleys are hung on a climbing section, a great impact force is generated when the walking plate passes the first pulley, which is likely to cause the angle steel to be knocked off and cause danger.

[0006] 3. The stress of the angle steel is not clear, and the stress between the two pulleys cannot be effectively supervised or balanced. CONTENT OF THE UTILITY MODEL

DETAILED DESCRIPTION

[0023] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below with reference to the accompanying drawings.

[0024] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0025] Secondly, the term "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in various places throughout this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0026] As attached Figure 1 To the attached Figure 4 As shown:

[0027] Embodiment 1: This embodiment provides an intelligent support device for connecting and fixing a double pulley, including a main body 1, including two pulleys 101, and a frame 102 arranged on both sides of the pulley 101; a support adjustment mechanism 2, including a shaft 201 arranged on the frame 102, a ring 203 arranged on the periphery of the shaft 201, a bearing 202 arranged between the shaft 201 and the ring 203, a linear drive 204 arranged on the ring 203, and a multi-dimensional force sensor 205 arranged between the linear drive 204.

[0028] The linear drive member 204 includes but is not limited to a hydraulic push rod;

[0029] A linear drive 204 is used to connect the two carriages 102 together to form a double pulley. During operation, the linear drive 204 can be activated according to the cross arm width designed for the tower. The linear drive 204 drives the carriages 102 to move. By changing the length of the linear drive 204 itself, the distance between the two carriages 102 can be adjusted to match the cross arm width designed for the tower, thereby increasing the applicability of the device.

[0030] In the process of setting the double pulley on the cross arm for the stringing work, the two carriages 102 are respectively suspended and fixed on the iron tower cross arm main material node through the steel wire rope. When the traction plate passes through the first pulley 101, pressure will be applied to the pulley, and the multi-dimensional force sensor 205 will detect the change in pressure. At this time, the linear drive member 204 will automatically start to adjust its length. The carriage 102 can rotate on the linear drive member 204 through the bearing 202. Since the carriage 102 is suspended and fixed on the cross arm by the steel wire rope, the levelness of the linear drive member 204 can be adjusted, so that the two carriages 102 are staggered up and down without changing the distance between the two carriages 102, automatically adjusting the pre-high of the pulley, without the need for manual adjustment of the pre-high by using an electric hoist, improving safety and stress accuracy. After the traction plate passes through the two pulleys smoothly, the multi-dimensional force sensor 205 will detect the change in pressure, and thus automatically drive the double pulley to return to the original position.

[0031] Specifically, the top and bottom of the linear drive member 204 are provided with limit blocks 206, and the linear drive members 204 are provided with a limiting rod 207, and the two ends of the limiting rod 207 are provided with blocking blocks 208 penetrating through the limit blocks 206.

[0032] Specifically, the support adjusting mechanism 2 is provided with two groups, and the two groups of support adjusting mechanisms 2 are located on the two sides of the carriage 102.

[0033] As can be seen from the above, the blocking blocks 208 limit the position of the limiting rod 207, avoiding its complete separation from the limiting block 206. The limiting rod 207 cooperates with the limiting block 206 to bear the main bending pressure when the device is not working without affecting the work of the multi-dimensional force sensor 205, improving the connection stability and durability between the multi-dimensional force sensor 205 and the linear drive member 204.

[0034] Embodiment two: the embodiment provides an intelligent support device for connecting and fixing a double pulley, which comprises a main body 1, two pulleys 101, and carriages 102 arranged on both sides of the pulleys 101; a support adjusting mechanism 2 comprising a shaft 201 arranged on the carriage 102, a sleeve ring 203 arranged on the periphery of the shaft 201, a bearing 202 arranged between the shaft 201 and the sleeve ring 203, a linear drive member 204 arranged on the sleeve ring 203, and a multi-dimensional force sensor 205 arranged between the linear drive members 204.

[0035] The linear drive member 204 includes but is not limited to an electric push rod;

[0036] Specifically, the top and bottom of the linear drive member 204 are provided with limit blocks 206, and the linear drive members 204 are provided with a limiting rod 207, and the two ends of the limiting rod 207 are provided with blocking blocks 208 penetrating through the limit blocks 206.

[0037] Specifically, the support adjusting mechanism 2 is provided with two groups, and the two groups of support adjusting mechanisms 2 are located on both sides of the frame 102.

[0038] Specifically, the threaded rods 103 are arranged between the frames 102 at the bottom of the pulleys 101, and the threaded rods 103 are threadedly connected with the nuts 104 at both ends.

[0039] Specifically, the fixed frames 105 are arranged between the frames 102 at the top of the pulleys 101, and the top of the fixed frame 105 is provided with a hanging ring 107.

[0040] Specifically, the frames 102 at the top of the fixed frame 105 are provided with clamping grooves 106, and the fixed frame 105 and the frame 102 are connected by connecting bolts 108.

[0041] As can be seen from the above, when the double pulley is suspended and installed, the suspension steel wire rope can be connected with the hanging ring 107 to suspend and fix the device on the iron tower cross arm main material, the threaded rod 103 and the nut 104 can cooperate to fix the lower end of the frame 102, the fixed frame 105 and the clamping groove 106 can cooperate to fix the upper end of the frame 102, the stability is improved, and the threaded rod 103 and the fixed frame 105 can be removed by rotating the nut 104 and the connecting bolt 108, so as to facilitate personnel to carry out maintenance and replacement work.
