[0032] The present disclosure will be described in detail below with reference to the drawings and in conjunction with embodiments.

[0033] First, please refer to Figure 1 and Figure 2 , Figure 1 which is a schematic structural view of an embodiment of the traction device for electric power construction of the present utility model; Figure 2 which is an exploded structural view of an embodiment of the traction device for electric power construction of the present utility model. As shown in Figure 1 and Figure 2 , the traction device for electric power construction of the present utility model includes a traction mechanism, a traction roller 6, and a clamping assembly for connecting the traction roller 6 and the transmission wheel 4.

[0034] The above-mentioned traction mechanism is placed on the base 1. The traction mechanism includes a motor 2, a main gear 3, a transmission wheel 4, and a transmission chain 5. The motor 2 is mounted on the base 1, the main gear 3 is mounted on the output end of the motor 2, the transmission wheel 4 is coaxially arranged with the traction roller 6, and the above-mentioned transmission chain 5 is arranged around the main gear 3 and meshes with the transmission wheel 4.

[0035] The traction roller 6 is arranged on one side of the transmission wheel 4, and a clamping assembly is connected to the transmission wheel 4. The clamping assembly includes a clamping rod 7, and the right end of the clamping rod 7 ( Figure 2 in the direction in

[0036] The clamping assembly further includes a clamping sleeve 8. A baffle 61 is fixedly provided at the hollow right side ( Figure 2 in the direction in Figure 2The right end (in the figure) can be fixedly connected to the inner side of the above-mentioned baffle 61 through bolts. The axis of the above-mentioned clamping sleeve 8 coincides with the axis of the baffle 61. The left end of the above-mentioned clamping rod 7 passes through the baffle 61 and is detachably connected to the clamping sleeve 8.

[0037] In the working state, the motor 2 is started to drive the main gear 3 to rotate. The transmission chain 5 is pulled by the rotation of the main gear 3. The transmission wheel 4 is driven to rotate by the transmission chain 5. The clamping rod 7 is driven to rotate by the transmission wheel 4. When the clamping rod 7 is connected to the clamping sleeve 8, the clamping rod 7 and the transmission wheel 4 can drive the clamping assembly and the traction roller 6 to rotate, so as to realize the automatic traction of the cable wound on the traction roller 6.

[0038] Please refer to Figure 3 , Figure 4 and Figure 5 , Figure 3 which is a schematic structural diagram of an embodiment of the clamping assembly of the present utility model; Figure 4 which is a schematic structural diagram of another embodiment of the clamping assembly of the present utility model; Figure 5 which is a cross-sectional view of another embodiment of the clamping assembly of the present utility model. As Figures 3 to 5 shown, the above-mentioned clamping rod 7 is inserted into the clamping sleeve 8. The above-mentioned clamping assembly further includes a plurality of clamping blocks 9, and the plurality of clamping blocks 9 are arranged around the clamping sleeve 8. The left end of the clamping block 9 ( Figure 5 in the direction in the figure) passes through the clamping sleeve 8 and can be engaged with the clamping rod 7.

[0039] The clamping sleeve 8 is provided with a plurality of relief holes 14. The clamping blocks 9 can all pass through the relief holes 14 movably. The clamping rod 7 is provided with a clamping groove 15, and the clamping groove 15 is adapted to the plurality of clamping blocks 9. Through the adaptation of the clamping groove 15 and the clamping blocks 9, a firm connection between the clamping blocks 9 and the clamping rod 7 is realized, so that when the traction mechanism drives the clamping rod 7 to rotate, the clamping blocks 9 and the clamping sleeve 8 can drive the traction roller 6 to rotate stably.

[0040] As Figure 5 shown, the above-mentioned clamping block 9 can be set in a cross shape, and the above-mentioned support rods 91 can be provided with four, which are respectively connected to the four sides of the cross-shaped clamping block 9. Further, the above-mentioned clamping groove 15 is provided with three layers, and each clamping block 9 can be engaged with the three layers of clamping grooves 15 after passing through the corresponding four relief holes 14. As Figure 5 shown in the direction, the uppermost support rod 91 is engaged with the uppermost clamping groove 15, the middle two support rods 91 are engaged with the middle clamping groove 15, and the lowermost support rod 91 is engaged with the lowermost clamping groove 15.

[0041] Furthermore, connection holes adapted to the number of support rods 91 to be mated can be provided on each clamping groove 15, so that the above-mentioned support rods 91 can be inserted into the connection holes one by one, thereby making the connection between the clamping block 9 and the clamping rod 7 more stable.

[0042] A tension spring 16 is connected between the inner side of the clamping block 9 and the clamping sleeve 8. The connection of the tension spring 16 provides elastic support, enabling the clamping block 9 to remain stable when subjected to a pulling force. At the same time, the design of the tension spring 16 helps to absorb and disperse forces, reducing wear and damage to the clamping block 9.

[0043] When disassembling the clamping rod 7, the worker can pull the clamping block 9 outwards. After overcoming the pulling force of the tension spring 16, the support rod 91 of the clamping block 9 is separated from the clamping rod 7, causing the clamping block 9 to be separated from the clamping rod 7. Finally, the clamping rod 7 can be pulled out to complete the disassembly.

[0044] When installing the clamping rod 7, the worker can pull the clamping block 9 outwards. Next, insert the clamping rod 7 into the clamping sleeve 8. Finally, the worker releases the clamping block 9. Under the pulling force of the tension spring 16, the support rod 91 of the clamping block 9 engages with the connection hole on the clamping rod 7 to complete the installation of the clamping rod 7.

[0045] Furthermore, the clamping assembly may further include a control sleeve 10, an inclined rod 11, a limit sleeve 12, and a rotating sleeve 13. The outer circumference of the above-mentioned clamping sleeve 8 is sequentially sleeved with a rotating sleeve 13, a limit sleeve 12, and a control sleeve 10 from the connection end to the open end ( Figure 5 as shown from bottom to top). The above-mentioned rotating sleeve 13 is rotatably connected to the clamping sleeve 8. As an example, a bearing can be provided between the rotating sleeve 13 and the clamping sleeve 8. The above-mentioned limit sleeve 12 and the control sleeve 10 are fixedly connected, and the above-mentioned limit sleeve 12 and the control sleeve 10 are slidably sleeved on the clamping sleeve 8. As an example, grooves can be provided on the outer circumference of the clamping sleeve 8, which are slidably connected to the guide rails provided on the inner walls of the limit sleeve 12 and the control sleeve 10.

[0046] The inclined rod 11 is arranged in the control sleeve 10, and the inclined rod 11 gradually inclines towards the axis of the clamping sleeve 8 along the direction from the open end to the connection end of the clamping sleeve 8. The right end ( Figure 5 in the direction shown) of the support rod 91 of the clamping block 9 is slidably connected to the inclined rod 11. The left end ( Figure 5 in the direction shown) of the support rod 91 of the clamping block 9 passes through the clamping sleeve 8 and can engage with the clamping rod 7.

[0047] The diagonal rods 11 can be arranged in pairs and sleeved on both sides of the support rods 91 of the clamping block 9. Since the support rods 91 are slidably installed in the diagonal rods 11, when the control sleeve 10 slides downward or upward, the diagonal rods 11 can drive the clamping block 9 to separate outward or approach inward, so that the clamping block 9 can be separated from or engaged with the clamping rod 7, thus realizing the disassembly and installation of the clamping rod 7.

[0048] When the rotating sleeve 13 rotates, it can limit the distance from the limiting sleeve 12, thereby locking the separation and engagement states of the clamping block 9 and the clamping rod 7. The rotating sleeve 13 is provided with insertion rods 17, and there are multiple insertion rods 17. Stopping blocks 18 are provided on all the multiple insertion rods 17. An arc-shaped groove 19 is formed on the limiting sleeve 12, and the number of the arc-shaped grooves 19 corresponds to the number of the stopping blocks 18. The diameter of one end of each arc-shaped groove 19 is larger than that of the stopping block 18. A pushing spring 20 is provided on the rotating sleeve 13, and there are multiple pushing springs 20. The arrangement of the pushing springs 20 provides additional elastic support. In order to facilitate the rotation of the rotating sleeve 13, anti-slip lines 21 are arranged on the outer wall of the rotating sleeve 13.

[0049] When the clamping block 9 and the clamping rod 7 are in the engaged state, the upper ends of the insertion rods are engaged with the bottom of the limiting sleeve under the action of the pushing spring 20, so that the rotating sleeve 13 and the limiting sleeve 12 are firmly connected, so that the diagonal rods 11 and the clamping block 9 are in a static state, so that the clamping block 9 and the clamping rod 7 are locked in the engaged state.

[0050] When the rotating sleeve 13 is rotated, overcoming the pulling force of the pushing spring 20, driving the multiple insertion rods 17 to rotate, and the multiple insertion rods 17 move to the position where the diameter of the arc-shaped groove 19 is larger than that of the stopping block 18, pushing the control sleeve 10 downward, so that the multiple clamping blocks 9 slide along the inclined slideways formed by the multiple diagonal rods 11, so that the multiple clamping blocks 9 gradually expand outward, and at the same time stretching the multiple pulling springs 16, so as to disengage from the clamping rod 7. When the stopping block 18 passes through the arc-shaped groove 19, the top end of the insertion rod 17 can be engaged with the bottom surface of the control sleeve 10. Rotating the rotating sleeve 13 in the reverse direction, so that the multiple stopping blocks 18 move to the end where the diameter of the arc-shaped groove 19 is smaller than that of the stopping block 18, so that the clamping block 9 and the clamping rod 7 are locked in the separated state, and the clamping rod 7 can be pulled out to complete the disassembly.

[0051] When installing the clamping rod 7, insert the clamping rod 7 into the clamping sleeve 8, rotate the rotating sleeve 13 to drive the stopping block 18 on the insertion rod 17 to move to the end where the diameter of the arc-shaped groove 19 is larger than that of the stopping block 18. Under the action of the pushing spring 20, the limiting sleeve 12 and the control sleeve slide upward, and the diagonal rods 11 gradually push the clamping block 9 inward, so that the clamping block 9 is engaged with the clamping groove 15 of the clamping rod 7 to complete the installation of the clamping rod 7.

[0052] The rotation of the rotating sleeve 13 can achieve the function of restricting the distance from the limiting sleeve 12, and locking the connection state and separation state of the locking block 9 and the locking rod 7. It can not only keep the locking block 9 and the locking rod 7 firmly connected in the connection state, but also keep the locking block 9 and the locking rod 7 separated in the separation state, providing convenience for the disassembly and assembly of the locking rod 7.

[0053] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
