[0018] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description of this application is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining this application and are not intended to limit this application.

[0019] A rope changing machine is a specialized piece of equipment used in mine shaft hoisting systems to replace large hoisting wire ropes.

[0020] Taking a multi-rope friction hoist as an example, when there is a steel beam available at the wellhead, two wire rope buckles are usually used in conjunction with a hand-operated hoist to temporarily connect and fix the boom of the rope changing machine and the steel beam. The wire rope buckles and the wire ropes led out from the guide wheel at the front end of the boom of the rope changing machine are subjected to opposite forces, which can balance the force on the guide wheel and thus fix the rope changing machine.

[0021] However, when there are no steel beams available at the wellhead, how to fix the rope changing machine is an urgent problem to be solved.

[0022] Based on the above considerations, this application provides a rope changing cart fixing device, which can solve the problem of inconvenience in fixing the rope changing cart when there is no steel beam available at the wellhead in the prior art.

[0023] The specific implementation of this application will be described in detail below with reference to specific embodiments.

[0024] Please see Figures 1-3 The embodiments of this application provide a rope changing cart fixing device, including a column 10 and a diagonal brace 20. The lower end of the column 10 is fixed to the boom 21 of the rope changing cart 30, and the upper end of the column 10 abuts against the concrete beam 40 of the well tower body. The upper end of the diagonal brace 20 is fixed to the column 10, and the lower end of the diagonal brace 20 is clamped to the square steel of the rope changing cart 30. The direction of the pressure of the boom 31 on the column 10 is the same as the direction of the force on the wire rope 33 led out by the guide wheel 32 at the front end of the boom 31.

[0025] The column 10 refers to the rigid support component arranged between the boom 21 and the concrete beam 40. The column 10 and the wire rope 33 are respectively placed on the left and right sides of the guide wheel 32.

[0026] The wire rope 33 is subjected to force vertically upward. When the wire rope 33 is subjected to force, the guide wheel 32 will tend to move upward. Since the column 10 abuts between the boom 31 and the concrete beam 40, the column 10 will restrict the upward movement of the guide wheel 32. That is, the boom 31 exerts vertically upward pressure on the column 10, and this pressure is transmitted to the concrete beam 40 through the column 10.

[0027] When the wire rope 33 exerts a vertical upward pressure on the column 10 through the boom 31, the column 10 will also exert a downward reaction force on the boom 31. This reaction force cancels out the upward force on the wire rope 33, thereby balancing the force on the guide wheel 32.

[0028] The diagonal brace 20 is a rigid support component arranged between the column 10 and the rope changing cart 30. The upper end of the diagonal brace 20 is welded to the column 10, and the lower end is welded with a U-shaped clamping plate 21. The clamping plate 21 is connected to the square steel on the rope changing cart 30. The column 10, the diagonal brace 20 and the boom 31 form a stable triangular structure, which makes the force more reliable.

[0029] The rope changing cart fixing device provided in this application embodiment, by arranging the column 10 between the boom 31 of the rope changing cart 30 and the concrete beam 40 of the well tower body, the force on the guide wheel 32 will be transmitted to the concrete beam 40 through the column 10, which can balance the force on the guide wheel 32 and achieve the fixing of the rope changing cart.

[0030] Please see Figures 1-3 In some embodiments, the lower end of the column 10 and the upper arm 31 are provided with corresponding bolted connecting plates 12.

[0031] The column 10 can be made of seamless round steel pipe. A top plate 11 is welded to the top of the column 10, and the top plate 11 abuts against the lower surface of the concrete beam 40. A connecting plate 12 is welded to the lower end of the column 10. At the same time, a connecting plate 12 is welded to the upper surface of the boom 31. The two connecting plates 12 correspond to each other and are fixedly connected by bolts.

[0032] Please see Figures 1-3 In some embodiments, a pad 13 is sandwiched between the two connecting plates 12.

[0033] The pad 13 is clamped between the upper and lower connecting plates 12 to keep the column 10 clamped between the boom 31 and the concrete beam 40.

[0034] Please see Figures 1-3 In some embodiments, the interior of the column 10 is provided with a limiting column 14 that penetrates the pad 13.

[0035] The limiting post 14 extends through the connecting plate 12 and then extends below the column 10. At the same time, a through hole is provided on the pad 13 for the limiting post 14 to pass through. After the limiting post 14 passes through each pad 13 in sequence, it abuts against the upper surface of the connecting plate 12 on the boom 31, thereby fitting each pad 13 onto the outside of the limiting post 14 to ensure the stability of the installation position of the pad 13.

[0036] Optionally, the limiting post 14 and the upright post 10 are arranged coaxially.

[0037] Please see Figures 1-3 In some embodiments, the limiting post 14 is provided with a counterweight 15.

[0038] The counterweight 15 is installed inside the column 10 and is fixedly connected to the limiting column 14. The counterweight 15 will move downward under the action of gravity, thereby driving the limiting column 14 to move downward and ensuring that the lower end of the limiting column 14 abuts against the connecting plate 12 on the boom 31.

[0039] Optionally, the outer diameter of the counterweight 15 is equal to the inner diameter of the column 10. The counterweight 15 is slidably snapped into the inside of the column 10. The limiting post 14 is threadedly connected to the counterweight 15. The limiting post 14, the counterweight 15 and the column 10 are arranged coaxially.

[0040] Please see Figures 1-3 In some embodiments, the counterweight 15 is provided with a lever 16.

[0041] The lever 16 is connected to the counterweight 15 and extends to the outside of the column 10. The lever 16 is arranged radially along the column 10. A clearance groove 17 for the extension of the lever 16 is provided on the side wall of the column 10. The extension direction of the clearance groove 17 is parallel to the axis of the column 10. When the lever 16 slides inside the clearance groove 17, it will drive the counterweight 15 to slide inside the column 10, thereby driving the limiting column 14 to move up and down.

[0042] In the initial state, under the action of the counterweight 15, the lower end of the limiting column 14 will abut against the connecting plate 12 on the boom 31. Therefore, when it is necessary to add a pad 13, push the lever 16 to move upward along the clearance groove 17 a certain distance, and then insert the pad 13 under the connecting plate 12 at the lower end of the column 10 until it is adjusted so that the top plate 11 at the upper end of the column 10 abuts against the concrete beam 40. Then release the lever 16, and under the action of the counterweight 15, the limiting column 14 will pass through each pad 13 in sequence and finally abut against the connecting plate 12 on the boom 31. Finally, use bolts to fix the upper and lower connecting plates 12 together to fix the position of the column 10.

[0043] The above are merely preferred embodiments of this application and are not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
