Technical Field

[0001] The present invention relates to the technical field of electric power construction, and in particular to a traction device for electric power construction. Background Art

[0002] In the existing technology, during the construction of power lines, the traction device is one of the key equipment, which is used to provide the necessary traction when laying wires and cables. However, the existing traction device for power construction has certain technical limitations, especially in the clamping installation of the traction roller.

[0003] The relevant traction device is usually connected by a motor drive shaft and a traction roller by bolts or the like, which makes it inconvenient to disassemble and assemble the motor and the traction roller, thereby extending the construction preparation time and even causing delays in construction progress during emergency repairs or construction in complex environments. Summary of the invention

[0004] The content of the present invention is used to introduce the concepts in a brief form, which will be described in detail in the detailed implementation section below. The content of the present disclosure is not intended to identify the key features or essential features of the technical solution claimed for protection, nor is it intended to limit the scope of the technical solution claimed for protection.

[0005] The present invention provides a clamping assembly for a cable pulling roller to solve the technical problems mentioned in the above background technology part.

[0006] The clamping assembly for the cable traction roller of the present invention comprises a clamping rod and a clamping sleeve, wherein the clamping rod passes through the traction roller along the axis of the traction roller and is detachably inserted into the clamping sleeve;

[0007] The connecting end of the clamping sleeve is fixedly mounted on the traction roller; a rotating sleeve, a connected limiting sleeve and a control sleeve are sequentially sleeved from the connecting end to the open end of the clamping sleeve;

[0008] A plurality of inclined rods and a plurality of clamping blocks are arranged in the control sleeve, one end of the clamping block is slidably connected with the corresponding inclined rod, and the other end of the clamping block passes through the clamping sleeve;

[0009] In response to the control sleeve sliding toward or away from the rotating sleeve, the oblique rod drives the clamping block to separate from or engage with the clamping rod;

[0010] The rotating sleeve limits the distance between the rotating sleeve and the limiting sleeve by rotating, thereby locking the connection state between the clamping block and the clamping rod.

[0011] Optionally, the other end of the clamping rod is connected to a traction mechanism for driving the clamping rod to rotate.

[0012] Optionally, the clamping sleeve is provided with a plurality of clearance holes, the clamping block passes through the clearance holes, and the clamping rod is provided with a clamping groove, and the clamping groove is adapted to the clamping block.

[0013] Optionally, two ends of the oblique rod are fixed in the control sleeve, and the oblique rods are arranged in pairs and sleeved on both sides of the clamping block.

[0014] Optionally, the oblique rod gradually inclines toward the axis of the clamping sleeve along the direction from the open end to the connecting end of the clamping sleeve.

[0015] Optionally, a tension spring is connected between the inner side of the clamping block and the clamping sleeve.

[0016] Optionally, the rotating sleeve is provided with a plurality of insertion rods, and each of the insertion rods is provided with a stopper.

[0017] Optionally, a plurality of arc-shaped grooves are formed on the limiting sleeve, and a diameter of one end of each arc-shaped groove is larger than the stop block.

[0018] Optionally, a plurality of push springs are provided between the rotating sleeve and the limiting sleeve.

[0019] Optionally, the outer wall of the rotating sleeve is provided with anti-slip grooves.

[0020] The above-mentioned embodiments of the present invention have the following beneficial effects: through the clamping assembly for the cable traction roller of the present invention, the traction roller can be quickly clamped, the convenience of operation is improved, the preparation time of power construction is shortened, and the construction progress is accelerated.

[0021] Specifically, by sliding the control sleeve, the inclined rod and the clamping block can slide, so that the clamping block moves toward or away from the clamping rod, thereby engaging or disengaging the clamping block and the clamping rod, and connecting or disengaging the clamping rod and the clamping sleeve. In this way, the clamping rod can be quickly installed and disassembled.

[0022] Furthermore, the rotation of the rotating sleeve can realize the function of limiting the distance with the limiting sleeve. Since the control sleeve is connected to the limiting sleeve, the rotating sleeve can limit the sliding distance of the control sleeve. This allows the rotating sleeve to lock the connection state and separation state of the clamping block and the clamping rod. In this way, not only can the clamping block and the clamping rod be firmly connected in the engaged state, but also the clamping block and the clamping rod can be kept separated in the separated state, which provides convenience for disassembling and assembling the clamping rod.

[0023] During the rotation of the clamping rod, due to the locking of the clamping block, the clamping rod can drive the clamping sleeve and the traction roller to rotate together, thereby achieving traction of the cable by the traction roller. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] The present disclosure will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0036] First see Figure 1 and Figure 2 , Figure 1 It is a structural schematic diagram of an embodiment of the traction mechanism of the present invention; Figure 2 FIG. 1 is a schematic diagram of the exploded structure of an embodiment of a clamping assembly for a cable pulling roller of the present invention. Figure 1 and Figure 2 As shown, the clamping assembly for the cable traction roller of the present invention is used to connect the traction roller 6 and the traction mechanism.

[0037] The 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 transmission chain 5 is arranged around the driving gear 3 and the transmission wheel 4 in meshing.

[0038] 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, a clamping sleeve 8, a clamping block 9, a control sleeve 10, a tilting rod 11, a limiting sleeve 12 and a rotating sleeve 13. The right end of the clamping rod 7 ( Figure 2The base 1 is connected to the transmission wheel 4 in the direction of the center. Specifically, a bearing seat 71 is also provided on the base 1, and the right end of the clamping rod 7 is inserted into the transmission wheel 4 and the bearing seat 71 in sequence. The clamping rod 7 is fixedly connected to the transmission wheel 4, and the clamping rod 7 is rotatably connected to the bearing seat 71.

[0039] The hollow right side of the traction roller 6 ( Figure 2 The baffle 61 is fixedly provided at the connecting end ( Figure 2 The right end of the clamping rod 7 can be fixedly connected with the inner side of the baffle 61 by bolts. The axis of the clamping sleeve 8 coincides with the axis of the baffle 61. The left end of the clamping rod 7 passes through the baffle 61 and is detachably connected with the clamping sleeve 8.

[0040] In the working state, the starting motor 2 drives the main gear 3 to rotate, and the main gear 3 rotates to pull the transmission chain 5, and the transmission chain 5 drives the transmission wheel 4 to rotate, and the transmission wheel 4 drives the clamping rod 7 to rotate. When the clamping rod 7 is connected with 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.

[0041] See also Figure 3 , Figure 4 and Figure 5 , Figure 3 It is a structural schematic diagram of an embodiment of a clamping assembly for a cable pulling roller of the present invention; Figure 4 A cross-sectional view of an embodiment of a clamping assembly for a cable pulling roller of the present invention; Figure 5 Schematic diagram of the structure of the clamping block and the tension spring of the present invention. Figures 3 to 5 As shown, the above-mentioned clamping rod 7 is inserted into the inside of the clamping sleeve 8. The outer circumference of the above-mentioned clamping sleeve 8 is from the connecting end to the open end ( Figure 4 The rotating sleeve 13, the limiting sleeve 12 and the control sleeve 10 are sequentially sleeved (from bottom to top as shown). The rotating sleeve 13 is rotatably connected to the clamping sleeve 8. As an example, a bearing can be arranged between the rotating sleeve 13 and the clamping sleeve 8. The limiting sleeve 12 and the control sleeve 10 are fixedly connected, and the limiting sleeve 12 and the control sleeve 10 are slidably sleeved on the clamping sleeve 8. As an example, a groove can be arranged on the outer circumference of the clamping sleeve 8, which is slidably connected to the guide rail arranged on the inner wall of the limiting sleeve 12 and the control sleeve 10.

[0042] A plurality of clamping blocks 9 are arranged around the clamping sleeve 8, and the right end of the clamping block 9 ( Figure 4 The left end of the clamping block 9 is connected with a support rod 91 ( Figure 4The support rod 91 passes through the clamping sleeve 8 and can be engaged with the clamping rod 7. The inclined rod 11 is arranged in the control sleeve 10, and the inclined rod 11 gradually tilts toward the axis of the clamping sleeve 8 along the direction from the open end of the clamping sleeve 8 to the connecting end.

[0043] The clamping sleeve 8 is provided with a plurality of clearance holes 14, and the clamping blocks 9 can all movably pass through the clearance holes 14. The clamping rod 7 is provided with a clamping groove 15, which is adapted to the plurality of clamping blocks 9. Through the adaptation of the clamping groove 15 and the clamping block 9, a stable connection between the clamping block 9 and the clamping rod 7 is achieved, so that when the traction mechanism drives the clamping rod 7 to rotate, the clamping block 9 and the clamping sleeve 8 can drive the traction roller 6 to rotate stably.

[0044] like Figure 5 As shown, the above-mentioned clamping block 9 can be arranged in a cross shape, and the above-mentioned support rods 91 can be arranged in four pieces, which are respectively connected to the four sides of the cross-shaped clamping block 9. Further, the above-mentioned clamping groove 15 is arranged in three layers, and each clamping block 9 can be engaged with the three-layer clamping groove 15 through the corresponding four clearance holes 14. Figure 4 In the direction shown, the top support rod 91 is engaged with the uppermost clamping groove 15, the middle two support rods 91 are engaged with the middle clamping grooves 15, and the bottom support rod 91 is engaged with the bottommost clamping groove 15.

[0045] Furthermore, each layer of the clamping groove 15 can be provided with connection holes adapted to the number of supporting rods 91 to be matched, so that the above-mentioned supporting 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.

[0046] The oblique rods 11 can be arranged in pairs and sleeved on both sides of the clamping block 9. Since the clamping block 9 is slidably installed in the oblique rods 11, when the above-mentioned control sleeve 10 slides downward or upward, the oblique rods 11 can drive the clamping block 9 to separate outward or move inward. In this way, the clamping block 9 can be separated from or engaged with the clamping rod 7, thereby realizing the disassembly and installation of the clamping rod 7.

[0047] 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, so that the clamping block 9 can remain stable when subjected to traction. At the same time, the design of the tension spring 16 helps to absorb and disperse force, reducing wear and damage to the clamping block 9.

[0048] The rotating sleeve 13 can limit the distance from the limiting sleeve 12 when rotating, thereby locking the separation and engagement state of the clamping block 9 and the clamping rod 7. The rotating sleeve 13 is provided with an insertion rod 17, and a plurality of insertion rods 17 are provided, and a stopper 18 is provided on each of the plurality of insertion rods 17. The limiting sleeve 12 is provided with arc grooves 19, and the number of arc grooves 19 corresponds to the number of the above-mentioned stoppers 18. The diameter of one end of each arc groove 19 is larger than the stopper 18. The rotating sleeve 13 is provided with a push spring 20, and a plurality of push springs 20 are provided. The setting of the push spring 20 provides additional elastic support. In order to facilitate the rotation of the rotating sleeve 13, an anti-slip pattern 21 is provided on the outer wall of the rotating sleeve 13.

[0049] When the above-mentioned clamping block 9 and the clamping rod 7 are in an engaged state, the upper end of the above-mentioned insertion rod is engaged with the bottom of the limiting sleeve under the action of the push spring 20, so that the rotating sleeve 13 and the limiting sleeve 12 are firmly connected, so that the inclined rod 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 an engaged state.

[0050] When the rotating sleeve 13 is rotated, the pulling force of the push spring 20 is overcome, and the multiple plug rods 17 are driven to rotate. The multiple plug rods 17 move to the position where the diameter of the arc groove 19 is larger than the stopper 18, and the control sleeve 10 is pushed downward, so that the multiple clamping blocks 9 slide along the inclined slideway formed by the multiple inclined rods 11, so that the multiple clamping blocks 9 gradually expand outward, and at the same time, the multiple tension springs 16 are stretched, so as to be separated from the clamping rod 7. After the stopper 18 passes through the arc groove 19, the top of the plug rod 17 can engage with the bottom surface of the control sleeve 10, and the rotating sleeve 13 is rotated in the opposite direction, so that the multiple stoppers 18 move to the end where the diameter of the arc groove 19 is smaller than the stopper 18, so that the clamping block 9 and the clamping rod 7 are locked in a 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 stopper 18 on the insertion rod 17 to move to the end of the arc groove 19 where the diameter is larger than the stopper 18, and under the action of the push spring 20, the limit sleeve 12 and the control sleeve slide upward, and the inclined rod 11 gradually pushes the clamping block 9 inward, so that the clamping block 9 engages with the clamping groove 15 of the clamping rod 7, completing the installation of the clamping rod 7.

[0052] The rotation of the rotating sleeve 13 can realize the function of limiting the distance with the limiting sleeve 12, and lock the connection state and separation state of the clamping block 9 and the clamping rod 7. Not only can the clamping block 9 and the clamping rod 7 be firmly connected in the connection state, but also the clamping block 9 and the clamping rod 7 can be kept separated in the separation state, which provides convenience for disassembling and assembling the clamping 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 aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
