[0035] The embodiments of the present utility model will be described in detail below with reference to the drawings.

[0036] As Figures 1 - 6 shown, the present utility model discloses a cable installation adjusting frame, which includes a base 1. The base 1 has a rectangular frame structure. Two moving wheels 2 are respectively rotatably provided on the two opposite outer side walls of the base 1. A support frame 3 is provided on the base 1, and a cable winding wheel 4 is rotatably provided on the support frame 3. A cable is wound on the cable winding wheel 4.

[0037] A sliding frame is slidably provided on the base 1 below the cable winding wheel 4. Horizontal chutes 5 are respectively provided on the two opposite inner side walls of the base 1. The chutes 5 are perpendicular to the rotation axis of the cable winding wheel 4. The sliding frame is slidably connected to the chutes 5.

[0038] The sliding frame includes a sliding rod 6, a vertical rod 7 and a cross rod 8 connected in sequence. The sliding rod 6 is horizontally arranged. The two ends of the sliding rod 6 are respectively slidably connected to the chutes 5. The vertical rod 7 is vertically arranged in the middle of the sliding rod 6. The cross rod 8 is horizontally arranged on the top side wall of the vertical rod 7, and the cross rod 8 is parallel to the sliding direction of the sliding frame.

[0039] A position adjusting component is provided between the sliding rod 6 and the chute 5, and the position adjusting component can realize the position adjustment of the sliding rod 6 in the chute 5. The position adjusting component includes notches 17 provided inside the two ends of the sliding rod 6. The notches 17 are cylindrical and their axial direction is perpendicular to the setting direction of the chute 5. Groove holes coaxial with the notches 17 are provided on the end faces of the sliding rod 6 outside the notches 17. Disc-shaped sliders 16 with shapes adapted to the notches 17 are provided inside the notches 17. The outer wall of the slider 16 is in sliding contact with the inner wall of the notch 17. Insertion rods 15 coaxially connected thereto are provided on the side wall of the slider 16 close to the groove hole. The shape of the insertion rod 15 is adapted to the groove hole, and the insertion rod 15 slides in the groove hole. A first spring 22 is provided on the side of the slider 16 away from the groove hole. The first spring 22 is provided inside the notch 17 and its two ends are respectively connected to the slider 16 and the inner end face of the notch 17. A plurality of insertion holes 14 cooperating with the insertion rods 15 are provided on the inner wall of the chute 5. The plurality of insertion holes 14 are equidistantly arranged in the length direction of the chute 5.

[0040] A pull ring 9 is provided on the side of the vertical rod 7 away from the cross rod 8. Two guy wires 18 are connected to the pull ring 9. The two guy wires 18 pass through the vertical rod 7 and the sliding rod 6 and are respectively connected to the sliders 16 at both ends of the sliding rod 6. Corresponding wire holes 19 for the guy wires 18 to pass through are provided in the sliding rod 6 and the vertical rod 7. Under the elastic force of the first spring 22, the slider 16 slides towards the direction close to the slot hole, so that the plug rod 15 extends out of the slot hole and is inserted into the socket hole 14. At this time, the sliding rod 6 is fixed on the sliding groove 5. Pull the pull ring 9, the pull ring 9 drives the two guy wires 18 to pull the sliders 16 at both ends of the sliding rod 6. The slider 16 is pulled towards the inner side of the notch 17, and the plug rod 15 moves accordingly and disengages from the socket hole 14. At this time, the sliding rod 6 can slide in the sliding groove 5 to adjust the position. After the position is adjusted, release the pull ring 9. Under the elastic force of the first spring 22, the slider 16 slides towards the slot hole side to reset, and the plug rod 15 is inserted into the side socket hole 14 to fix the sliding rod 6 after the position is adjusted.

[0041] A cable guiding assembly is provided at one end of the cross rod 8 away from the vertical rod 7. The cable led out from the cable winding wheel 4 is output via the cable guiding assembly. The cable guiding assembly includes two guiding wheels 13 arranged up and down. The axial directions of the two guiding wheels 13 are parallel to the axial direction of the cable winding wheel 4. The wheel surface of the guiding wheel 13 is in a concave arch shape, that is, the outer diameter of the guiding wheel 13 gradually increases from the middle to both sides. A rubber layer is provided on the surface of the guiding wheel 13, which not only prevents the cable from slipping on the guiding wheel 13, but also makes the surface of the guiding wheel 13 have a certain elasticity and has a certain protective effect on the cable.

[0042] Fixing plates 10 are respectively rotatably connected to both ends of the lower guiding wheel 13. The fixing plates 10 are vertically arranged and connected to the cross rod 8. Moving plates 11 are respectively rotatably connected to both ends of the upper guiding wheel 13. Handles 12 for easy gripping by personnel are provided on the outer side walls of the two moving plates 11 away from the guiding wheel 13. A plate groove 20 is provided at the top of the fixing plate 10 and opened downward. The position of the plate groove 20 corresponds to the moving plate 11. The moving plate 11 is slidably arranged in the plate groove 20. The bottom of the moving plate 11 is connected with a vertically arranged second spring 21. The bottom end of the second spring 21 is connected to the inner bottom of the plate groove 20. The elastic force of the second spring 21 pulls the moving plate 11 to slide into the fixing plate 10, so that the distance between the two guiding wheels 13 is smaller.

[0043] When installing cables in a hoistway or sewer, the base 1 is pushed to the wellhead or sewer opening by the moving wheel 2, and then the pull ring 9 is pulled, so that the guy wire 18 pulls the slider 16, and the insertion rods 15 at both ends of the slide bar 6 are disengaged from the insertion holes 14 of the chute 5. Then, the carriage is slid to adjust the position of the cable guiding assembly so that the cable guiding assembly is above the center of the wellhead or sewer opening. Then, the pull ring 9 is released, and the slider 16 is reset under the elastic force of the first spring 22, and the insertion rod 15 is inserted into the insertion hole 14 at the corresponding position to fix the carriage. The cable on the cable reel 4 is led out, and the cable passes through between the two guide wheels 13. During this process, the two movable plates 11 are lifted by the handle 12, so that the upper guide wheel 13 moves upward. After the cable passes through between the two guide wheels 13, the handle 12 is released, and the movable plate 11 slides downward under the elastic force of the second spring 21, driving the upper guide wheel 13 to slide downward. The two guide wheels 13 cooperate to clamp the cable, and the two guide wheels 13 are respectively in contact with the upper surface and the lower surface of the cable. After the cable passes through the two guide wheels 13, it is input downward into the hoistway or sewer. Since the cable enters downward from above the wellhead or sewer opening, the cable will not slide into contact with the wellhead or sewer opening, and there is also a gap between the cable and the hoistway wall or sewer wall. The friction between the cable and the hoistway or sewer is reduced or avoided during the process of leading out and transporting the cable.

[0044] Through the position adjustment of the carriage, the position where the cable is input into the hoistway or sewer is in the middle of the wellhead or sewer opening, which can reduce or avoid the friction between the cable and the hoistway or sewer, avoid cable scratching or outer wall wear, ensure the integrity of the cable outer protective layer and the safety of cable use, improve the construction quality of cable installation work, and the position adjustment and fixation of the carriage can be achieved by pulling the pull ring 9, and the operation is simple and convenient.

[0045] The above embodiments are only the preferred embodiments of the present invention, and do not limit the technical solutions of the present invention. As long as the technical solutions that can be achieved on the basis of the above embodiments without creative labor shall be regarded as falling within the scope of the patent rights of the present invention.
