Description

Technical Field

[0001] This utility model relates to the field of winch fixing technology, and in particular to a winch fixing device for furnace and kiln hoisting formwork construction. Background Technology

[0002] In the construction of furnace and kiln formwork, the winch is the core vertical and oblique traction equipment. It mainly undertakes key operations such as hoisting, positioning, adjusting and dismantling of formwork such as refractory castable templates and brick masonry auxiliary templates. Its role is to replace manpower with mechanical force to ensure construction accuracy, efficiency and safety.

[0003] In the scenario of hoisting molds in furnaces and kilns, the molds are heavy, the working height is high, and the environment is often high or confined. If the hoist exceeds the load limit, the motor may be overloaded and the winding restraint may be released, causing the goods to fall and resulting in a safety accident. This reduces the safety measures for hoist overload fixation.

[0004] To address this issue, a winch fixing device for furnace and kiln formwork construction is proposed. Utility Model Content

[0005] To overcome the above deficiencies, this utility model provides a winch fixing device for furnace and kiln formwork construction. It aims to improve the existing technology in furnace and kiln formwork scenarios where the formwork is heavy, the working height is high, and the environment is mostly high-altitude or confined space. If the winch lifts beyond its load limit, the motor is prone to overload and release the winding restraint force, resulting in idling and causing the goods to fall and cause safety accidents. This reduces the safety measures for winch overload fixing.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A winch fixing device for furnace and kiln formwork construction includes a steel frame. Supports are fixedly connected to the left and right sides of the top of the steel frame. A winding drum is movably connected to the inner side of each support via bearings. A drive motor is installed at the front end of the top of the steel frame. A fixing mechanism is fixedly connected to the right side of each support. The fixing mechanism includes a bearing plate, a ratchet, and a synchronous shaft. The bearing plate is fixedly connected to the right side of the support. The ratchet is movably connected to the left side of the bearing plate via bearings. The synchronous shaft is fixedly connected to the right side of the ratchet. The left side of the synchronous shaft passes through a bearing and is fixedly connected to the right side of the winding drum. A skip-tooth mechanism is fixedly connected to the left side of the inner wall of the bearing plate.

[0008] The above technical solution involves starting the drive motor and using the pulley to rotate the winding drum clockwise to release the wire rope lifting device. When the wire rope lifting device exceeds the upper limit, the drive motor becomes overloaded and loses its driving force. The synchronous shaft then rotates synchronously with the winding drum. The rotation of the synchronous shaft drives the ratchet to rotate, and the ratchet rotation, combined with external mechanical locking teeth, restricts the ratchet's rotation. The ratchet's restricted rotation locks the synchronous shaft and the winding drum, stopping the winding drum and fixing the position of the wire rope lifting device and the cargo, thus preventing the danger of falling.

[0009] As a further description of the above technical solution: the skip tooth mechanism includes a support column, a pawl, and a connector. The support column is fixedly connected to the left side of the inner wall of the support plate. The pawl is movably sleeved on the surface of the support column. The end of the pawl away from the support column contacts the top of the ratchet. The connector is fixedly connected to the right side of the pawl. A plug-in assembly is fixedly connected to the right side of the inner wall of the support plate.

[0010] Through the above technical solution, the setting of the skipping tooth mechanism enables the ratchet to rotate clockwise normally and contact the pawl. The pawl, affected by the teeth, rotates around the support column and skips the teeth. During the skipping process, the pawl synchronously drives the connector to rotate, thereby realizing that the pawl does not affect the normal rotation of the ratchet.

[0011] As a further description of the above technical solution: the plug-in assembly includes an electric telescopic rod and a positioning rod. The electric telescopic rod is fixedly connected to the right side of the inner wall of the bearing plate. The top and bottom of the left side of the electric telescopic rod are fixedly connected to the positioning rod. A guide assembly is fixedly connected to the right side of the inner wall of the bearing plate and at the back end of the electric telescopic rod.

[0012] Through the above technical solution, the setting of the plug-in component can activate the electric telescopic rod to work. The electric telescopic rod pushes the positioning rod to move to the left, and the positioning rod moves to the right side of the connector for plug-in fixation. The connector restricts the positioning rod from rotating, so the pawl cannot rotate either. The pawl cannot rotate, so it is pressed tightly against the surface of the ratchet and jams the ratchet, thereby achieving active restriction of the ratchet and preventing the pawl from rotating.

[0013] As a further description of the above technical solution: the guide assembly includes a rectangular plate and a slider. The rectangular plate is fixedly connected to the right side of the inner wall of the bearing plate and to the back end of the electric telescopic rod. The slider is slidably connected to the front end of the rectangular plate. The front end of the slider is fixedly connected to the back end of the electric telescopic rod. A reset assembly is fixedly connected to the left side of the inner wall of the bearing plate.

[0014] Through the above technical solution, the guide component can be set so that the electric telescopic rod can extend and retract synchronously to drive the slider to move, and the slider can move horizontally along the rectangular plate, thereby achieving stable mechanical movement direction.

[0015] As a further description of the above technical solution: the reset assembly includes a support and a spring, the support is fixedly connected to the left side of the inner wall of the bearing plate, the bottom of the support is fixedly connected to the spring, and the bottom of the spring is fixedly connected to the top of the pawl.

[0016] Through the above technical solution, the reset component can compress the spring as the pawl jumps on the surface of the ratchet. The spring is compressed and stores elastic kinetic energy until the pawl jumps over the teeth of the ratchet and actively pushes the pawl to reset, so that the machine always fits the ratchet to work.

[0017] As a further description of the above technical solution: a slide rail is provided at the front end of the rectangular plate and at the position corresponding to the slider, and the slide rail is used in conjunction with the slider.

[0018] Through the above technical solution, the slide rail can assist the slider in its work and also serve as a limit, preventing the slider from deviating during its movement.

[0019] This utility model has the following beneficial effects:

[0020] 1. In this utility model, the arrangement of the bearing plate, ratchet, and synchronous shaft enables the drive motor to work in conjunction with the pulley to drive the winding drum to rotate clockwise and release the wire rope lifting device. When the wire rope lifting device exceeds the upper limit, the drive motor is overloaded and loses driving force, and the synchronous shaft rotates synchronously with the winding drum. The rotation of the synchronous shaft drives the ratchet to rotate, and the rotation of the ratchet, in conjunction with the external mechanical locking teeth, restricts the rotation of the ratchet. The ratchet is restricted from rotating, thereby locking the synchronous shaft and the winding drum, stopping the winding drum and fixing the position of the wire rope lifting device and the goods, thus avoiding the danger of falling.

[0021] 2. In this utility model, the arrangement of the support column, pawl, and connector allows the ratchet to rotate clockwise and contact the pawl. The pawl, influenced by the teeth, rotates around the support column and skips teeth. During the pawl's skipping motion, the connector rotates synchronously, thus ensuring that the pawl does not affect the normal rotation of the ratchet. Similarly, the pawl can be used to actively fix the position, forcing the ratchet to stop rotating, thereby controlling the winding drum to stop rotating and fixing the position of the wire rope lifting device and the goods to avoid the danger of falling.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Reference Figure 1-5 This utility model provides an embodiment of a winch fixing device for furnace and kiln formwork construction, comprising a steel frame 1, with brackets 2 fixedly connected to the left and right sides of the top of the steel frame 1, and a winding drum 3 movably connected to the inner side of the brackets 2 via bearings. A drive motor 4 is provided at the front end of the top of the steel frame 1, and a fixing mechanism 5 is fixedly connected to the right side of the brackets 2. The fixing mechanism 5 includes a bearing plate 51, a ratchet 52, and a synchronous shaft 53. The bearing plate 51 is fixedly connected to the right side of the brackets 2, and the ratchet 52 is movably connected to the left side of the bearing plate 51 via bearings. The synchronous shaft 53 is fixedly connected to the right side of the ratchet 52, and the left side of the synchronous shaft 53 passes through the bearing and is connected to... The right side of the winding drum 3 is fixedly connected, and the left side of the inner wall of the bearing plate 51 is fixedly connected to the skip tooth mechanism 6. When in use, the drive motor 4 is started and works in conjunction with the pulley to drive the winding drum 3 to rotate clockwise to release the wire rope lifting device. When the wire rope lifting device lifts goods beyond the upper limit, the drive motor 4 is overloaded and loses driving force, and the synchronous shaft 53 rotates synchronously with the winding drum 3. The rotation of the synchronous shaft 53 drives the ratchet 52 to rotate, and the rotation of the ratchet 52, in conjunction with the external mechanical locking teeth, restricts the rotation of the ratchet 52. The ratchet 52 is restricted and cannot rotate, thus locking the synchronous shaft 53 and the winding drum 3. The winding drum 3 stops rotating, thus fixing the position of the wire rope lifting device and the goods and avoiding the danger of falling.

[0031] Reference Figure 1-5The skipping mechanism 6 includes a support column 61, a pawl 62, and a connector 63. The support column 61 is fixedly connected to the left side of the inner wall of the support plate 51. The pawl 62 is movably sleeved on the surface of the support column 61. The end of the pawl 62 away from the support column 61 contacts the top of the ratchet 52. The connector 63 is fixedly connected to the right side of the pawl 62. A plug-in assembly 7 is fixedly connected to the right side of the inner wall of the support plate 51. Through the setting of the skipping mechanism 6, the ratchet 52 can rotate clockwise normally to contact the pawl 62. The pawl 62, affected by the teeth, rotates around the support column 61 to skip teeth. During the skipping process, the pawl 62 synchronously drives the connector 63 to rotate, thereby ensuring that the pawl 62 does not affect the normal rotation of the ratchet 52. The plug-in assembly 7 includes an electric telescopic rod 7. 1. An electric telescopic rod 71 is fixedly connected to the right side of the inner wall of the bearing plate 51. The top and bottom of the left side of the electric telescopic rod 71 are fixedly connected to the positioning rod 72. A guide assembly 8 is fixedly connected to the right side of the inner wall of the bearing plate 51 and at the back end of the electric telescopic rod 71. By setting the plug-in assembly 7, the electric telescopic rod 71 can be started to work. The operation of the electric telescopic rod 71 pushes the positioning rod 72 to move to the left. The positioning rod 72 moves to the right side of the connector 63 for plug-in fixation. The connector 63 restricts the positioning rod 72 from rotating, so that the pawl 62 can also not rotate. The pawl 62 cannot rotate, so it is pressed against the surface of the ratchet 52 and jams the ratchet 52, thereby realizing that the ratchet 52 is actively restricted and the pawl 62 cannot rotate.

[0032] Reference Figure 1-5 The guide assembly 8 includes a rectangular plate 81 and a slider 82. The rectangular plate 81 is fixedly connected to the right side of the inner wall of the bearing plate 51 and to the back end of the electric telescopic rod 71. The slider 82 is slidably connected to the front end of the rectangular plate 81, and the front end of the slider 82 is fixedly connected to the back end of the electric telescopic rod 71. A reset assembly 9 is fixedly connected to the left side of the inner wall of the bearing plate 51. Through the guide assembly 8, the electric telescopic rod 71 can synchronously drive the slider 82 to move during operation, while the slider 82 maintains horizontal movement along the rectangular plate 81, thereby achieving stable mechanical movement. The reset assembly 9 includes a support 91 and a spring 92. The support 91 is fixedly connected to the left side of the inner wall of the bearing plate 51. A spring 92 is fixedly connected to the bottom of the device. The bottom of the spring 92 is fixedly connected to the top of the pawl 62. With the reset component 9, the pawl 62 can compress the spring 92 as it bounces on the surface of the ratchet 52. The spring 92 stores elastic kinetic energy under compression until the pawl 62 jumps over the teeth of the ratchet 52 and actively pushes the pawl 62 to reset, so that the machine always fits the ratchet 52 to work. A slide rail 10 is provided at the front end of the rectangular plate 81 and at the position corresponding to the slider 82. The slide rail 10 works with the slider 82. The slide rail 10 can assist the slider 82 in working and also play a limiting role to prevent the slider 82 from deviating during movement.

[0033] Working principle: When in use, the start drive motor 4, in conjunction with the pulley, drives the winding drum 3 to rotate clockwise to release the wire rope lifting device. When the wire rope lifting device exceeds the upper limit, the drive motor 4 is overloaded and loses driving force, coordinating with the synchronous shaft 53 to rotate synchronously with the winding drum 3. The rotation of the synchronous shaft 53 drives the ratchet 52 to rotate, and the ratchet 52 rotates clockwise to contact the pawl 62. The pawl 62, affected by the teeth, rotates around the support 61 and skips teeth. During the skipping process, the pawl 62 synchronously drives the coupling 63 to rotate, thus ensuring that the pawl 62 does not affect the normal rotation of the ratchet 52. As the pawl 62 skips on the surface of the ratchet 52, it compresses the spring 92, and the spring 92 stores elastic kinetic energy. Until the pawl 62 skips the teeth of the ratchet 52 and actively pushes the pawl 62 to return to its original position, the machine always keeps in contact with the ratchet 52 for operation.

[0034] The electric telescopic rod 71 is activated, pushing the positioning rod 72 to the left. The positioning rod 72 moves to the right side of the connector 63 for insertion and fixation. During operation, the electric telescopic rod 71 extends and retracts, simultaneously driving the slider 82 to move. The slider 82 moves horizontally along the slide rail 10 at the front end of the rectangular plate 81, thus stabilizing the mechanical movement direction. Finally, the connector 63 restricts the positioning rod 72 from rotating, thereby preventing the pawl 62 from rotating. The pawl 62's inability to rotate causes it to press tightly against the surface of the ratchet 52, locking the ratchet 52. This achieves the active restriction of the ratchet 52, preventing the pawl 62 from rotating.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
