DETAILED DESCRIPTION

[0025] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0026] See also Figures 1 to 8 As shown, the busbar lifting frame clamp personnel anti-fall suspension device is used for placing a pedal 1 on the busbar lifting frame for people to walk on, and a suspension mechanism 2 is arranged on the pedal 1, and the suspension mechanism 2 includes a first steel frame 21, a second steel frame 22, a fixing seat 23 and a steel wire rope 24; the first steel frame 21 has a plurality of equidistantly arranged, and the plurality of first steel frames 21 are fixed to one side of the pedal 1 with a fixing seat 23, and a second steel frame 22 is movably arranged on the top of each first steel frame 21, and a tensioning assembly 3 is arranged between the corresponding first steel frame 21 and the second steel frame 22; the steel wire rope 24 is arranged between the first steel frame 21 and the second steel frame 22.

[0027] When the operator needs to operate on the top of the busbar lifting frame, first, the operator needs to step on the pedal 1 set on the top of the busbar lifting frame to operate the busbar lifting frame. Since the busbar lifting frame itself is a very large device, the suspension mechanism 2 installed on the pedal 1 allows the operator to buckle the safety belt tied to the body to the suspension mechanism 2 when walking or operating on the pedal 1. This can effectively eliminate the risk of the operator falling from the busbar lifting frame during operation or walking. The cooperation of the first steel frame 21, the second steel frame 22, the fixed seat 23 and the wire rope 24 in the suspension mechanism 2 makes the structure of the suspension mechanism 2 simple and the assembly and disassembly process is relatively convenient. The first steel frame 21 is fixed on the pedal 1 through the setting of the fixed seat 23, and the second steel frame 22 is restricted to the top of the first steel frame 21 through the tensioning component 3. The steel wire rope 24 is located between the first steel frame 21 and the second steel frame 22, and the two ends of the steel wire rope 24 are respectively fixed between the first steel frame 21 and the second steel frame 22 at the starting end and the end end of the stepping pedal 1. Through the arrangement of the first steel frame 21 and the second steel frame 22, the steel wire rope 24 is installed above the stepping pedal 1 and tightened for hanging the safety belt. Through the cooperation of the first steel frame 21, the second steel frame 22 and the tensioning mechanism, when the operator walks on the stepping pedal 1, when the safety belt on the operator needs to be transferred from one side of the first steel frame 21 and the second steel frame 22 to the other side, there is no need to remove the safety belt from the steel wire rope 24 and then buckle it on the steel wire rope 24 again. It is only necessary to operate the tensioning component 3 to form a gap between the second steel frame 22 and the first steel frame 21 for the safety belt to pass through. In this way, the safety hazard that occurs when the operator adjusts the position of the safety belt can be eliminated, which greatly improves the safety production coefficient.

[0028] See also Figure 3 As shown, a first limiting groove 211 is formed on one end of the first steel frame 21 close to the second steel frame 22 , and a second limiting groove 221 corresponding to the first limiting groove 211 is formed on one end of the second steel frame 22 close to the first steel frame 21 .

[0029] By respectively opening the first limiting groove 211 and the second limiting groove 221 on the first steel frame 21 and the second steel frame 22, the steel wire rope 24 can be limited when passing through between the first steel frame 21 and the second steel frame 22 to prevent the position of the steel wire rope 24 from deviation.

[0030] See also Figure 2 and Figure 5As shown, the tensioning assembly 3 includes a mounting member 31 and a telescopic member 32; the mounting member 31 is arranged on the same side of the first steel frame 21 and the second steel frame 22; the telescopic member 32 has a plurality of equidistantly arranged members on the mounting member 31, and both ends of the telescopic member 32 are respectively connected to the same side of the first steel frame 21 and the second steel frame 22 through the mounting member 31.

[0031] By setting the mounting parts 31, a plurality of telescopic parts 32 are installed between the first steel frame 21 and the second steel frame 22. By setting the plurality of telescopic parts 32, the second steel frame 22 can move up and down on the first steel frame 21. When the second steel frame 22 moves upward to a specified position, a gap is formed between the second steel frame 22 and the first steel frame 21 for the operator's safety belt to pass through, so that the operator can directly move the safety belt on the steel wire rope 24 from one side of the first steel frame 21 and the second steel frame 22 to the other side without taking off the safety belt and re-fastening it to the steel wire rope 24. This can avoid safety hazards when the operator operates the safety belt.

[0032] See also Figure 3 and Figure 5 As shown, the mounting member 31 includes a first mounting frame 311 and a second mounting frame 314; the first mounting frame 311 is arranged on one side of the first steel frame 21; the second mounting frame 314 is arranged on one side of the second steel frame 22, the first mounting frame 311 and the second mounting frame 314 are both located on the same side of the first steel frame 21 and the second steel frame 22, the first mounting frame 311 and the second mounting frame 314 are respectively fixed to the first steel frame 21 and the second steel frame 22 by a plurality of fixing bolts 312 and fixing nuts 313, and the ends of the first mounting frame 311 and the second mounting frame 314 that are close to each other are respectively connected to the two ends of a plurality of telescopic members 32.

[0033] The first mounting frame 311 and the second mounting frame 314 are fixed to the first steel frame 21 and the second steel frame 22 respectively by the cooperation of a plurality of fixing bolts 312 and fixing nuts 313. By the arrangement of the first mounting frame 311 and the second mounting frame 314, the two ends of a plurality of telescopic members 32 are connected to the first steel frame 21 and the second steel frame 22 respectively.

[0034] See also Figure 3 , Figure 5 and Figure 6As shown, the telescopic member 32 includes a support tube 321, an insertion rod 322, a tension spring 323 and a connecting portion 324; the support tube 321 is vertically arranged on a first mounting frame 311 located on the first steel frame 21; the insertion rod 322 is arranged on a second mounting frame 314 on the second steel frame 22, and one end of the insertion rod 322 away from the first mounting frame 311 extends into the support tube 321; the tension spring 323 is arranged in the support tube 321, and both ends of the tension spring 323 are fixedly connected to the bottom of the support tube 321 and one end of the insertion rod 322 extending into the support tube 321 through the connecting portion 324.

[0035] By setting the connecting part 324, the tension spring 323 located in the support tube 321 is connected to the insertion rod 322 and the bottom of the support tube 321 respectively. By the cooperation of the support tube 321, the insertion rod 322 and the tension spring 323, the first mounting frame 311 and the second mounting frame 314 are connected together, and then the first steel frame 21 and the second steel frame 22 are connected together. When it is necessary to form a gap between the first steel frame 21 and the second steel frame 22 for the safety belt to pass through, the operator only needs to pull the second steel frame 22 upwards. , which will synchronously drive the insertion rod 322 on the second mounting frame 314 to move upward, and the tension spring 323 will be stretched, so that a gap for the safety belt to pass through will appear between the second steel frame 22 and the first steel frame 21. When the safety belt is transferred from one side of the first steel frame 21 and the second steel frame 22 to the other side, the second steel frame 22 is released, and the insertion rod 322 can be automatically moved downward into the support tube 321 through the automatic elastic force of the stretched tension spring 323, so that the second steel frame 22 is further returned to the first steel frame 21 and fixed again.

[0036] See also Figure 7 As shown, symmetrically arranged linear grooves 3211 are opened on both sides of the support tube 321, and a first through hole 3221 is opened on the outside of one end of the insertion rod 322 inserted into the support tube 321. A latch 325 is set in the first through hole 3221, and both ends of the latch 325 extend to the linear grooves 3211 opened on both sides of the support tube 321 respectively.

[0037] When one end of the insertion rod 322 with the first through hole 3221 is inserted into the support tube 321, one end of the pin 325 is inserted into the first through hole 3221 of the insertion rod 322 from the linear groove 3211 on one side of the support tube 321 and extends to the linear groove 3211 on the other side of the support tube 321. Through the cooperation of the linear groove 3211 and the pin 325, the insertion rod 322 can be prevented from escaping from the support tube 321.

[0038] See also Figure 6 and Figure 8As shown, the connecting portion 324 includes a first connecting block 3241, a second connecting block 3242, a locking bolt 3243 and a locking nut 3244; the first connecting block 3241 is arranged at the bottom of the support tube 321, the first connecting block 3241 is fixedly connected to one end of the tension spring 323 in the support tube 321, and a second through hole 32421 is provided on the first connecting block 3241; the second connecting block 3242 is arranged on one end of the insertion rod 322 extending to the support tube 321, and the end of the second connecting block 3242 away from the insertion rod 322 is fixedly connected to the other end of the tension spring 323; one end of the locking bolt 3243 passes through the support tube 321 and the second through hole 32421 opened by the first connecting block 3241 in sequence and extends out of the support tube 321; the locking nut 3244 is arranged on one end of the locking bolt 3243 extending out of the support tube 321.

[0039] By setting the second connecting block 3242, one end of the tension spring 323 is connected to one end of the insertion rod 322. When the first connecting block 3241 is connected to the end of the tension spring 323 away from the insertion rod 322 and the first connecting block 3241 is located at the bottom of the support tube 321, the first connecting block 3241 is temporarily fixed to the bottom of the support tube 321 by the locking bolt 3243 and the locking nut 3244. By the cooperation of the first connecting block 3241 and the second connecting block 3242, the two ends of the tension spring 323 are respectively connected to the bottom of the support tube 321 and the end of the insertion rod 322 extending into the support tube 321, thereby preventing the insertion rod 322 from bringing out the tension spring 323 when moving upward in the support tube 321, thereby causing the tension spring 323 to be unable to be stretched.

[0040] See also Figure 4 As shown, two symmetrically arranged threaded holes 222 are provided on one end of the second steel frame 22 close to the first steel frame 21, and a positioning rod 223 is respectively provided in the two threaded holes 222.

[0041] By means of the threaded hole 222 provided on the second steel frame 22, one end of the positioning rod 223 provided with the external thread 2231 can be fixed on the second steel frame 22. By means of the positioning hole 212 corresponding to the threaded hole 222 provided on the first steel frame 21, when the second steel frame 22 is placed on the first steel frame 21, the positioning rod 223 in the second steel frame 22 can be inserted into the positioning hole 212 provided in the first steel frame 21. By means of the cooperation between the positioning rod 223 and the positioning hole 212, the positions of the first steel frame 21 and the second steel frame 22 will not be misaligned during the assembly process. At the same time, the second steel frame 22 can play a guiding role when moving upward in the first steel frame 21, thereby avoiding the deviation of the positions of the second steel frame 22 and the first steel frame 21, which would affect the fixation of the steel wire rope 24.

[0042] See also Figure 3 As shown, a handle 224 is provided on the second steel frame 22 .

[0043] The provision of the handle 224 makes it easier to pull the second steel frame 22 .
