Description

Technical Field

[0001] This utility model relates to the field of lifting equipment, specifically to a locking and guiding integrated device for a water tank lifting platform. Background Technology

[0002] The water tank lifting platform deployment and retrieval system primarily uses steel wire ropes to control and drive the platform's vertical movement. To ensure the smoothness of this process, a guide structure is needed to restrict horizontal movement. Simultaneously, a locking device is required to ensure the platform stops safely and smoothly at the desired position. Furthermore, because this system enables cross-domain deployment and retrieval between the water surface and underwater, the locking device cannot be operated visually; therefore, automatic operation is necessary for platform locking. Additionally, the platform is relatively large, requiring multiple locking devices to ensure effective and stable locking, necessitating the synchronized operation of these devices. Currently, there are many types of lifting platform products, mainly including land-based aerial work platforms, lifting platforms, water-based lifting platforms, and ship-based lifting platforms. The main drive methods of these lifting platforms include wire rope drive, scissor-type hydraulic cylinder drive, direct hydraulic cylinder drive, gear and rack drive, and pin-type hydraulic cylinder drive. Some of them have locking devices and some do not, some have guide devices and some do not. Moreover, there are basically no two types of devices integrated into one unit. Most of them use pin-type locking devices.

[0003] For example, patent application number CN201911202150.X discloses a lifting platform. A locking device for the lifting platform includes: a base, a rack, and a locking mechanism; the base provides support for the lifting platform's movement; the rack is longitudinally mounted on one side of the base; the locking mechanism is fixedly connected to the lifting platform and moves along the base with the lifting platform; the locking mechanism includes: a ratchet structure; the ratchet structure engages with the rack, and when the ratchet structure is engaged with the rack, the lifting platform is locked; when the ratchet structure disengages from the rack, the lifting platform is unlocked. The drawback is that this patented technology uses a ratchet structure to move laterally and engage with a rack to fix the platform position. Since the lifting platforms used in the shipbuilding industry are usually heavily loaded, the ratchet structure moves horizontally and extends. When the upper part of the platform is subjected to force, the gravity acts vertically on the horizontally positioned ratchet structure. In actual use, the teeth are engaged and fixed. Under the action of gravity, an overturning moment is generated with the tooth tip as the center of rotation. In addition, in order for the ratchet structure to extend and retract more freely, there must be sufficient clearance between its perimeter and the sliding sleeve. This makes it easier for the ratchet structure to rotate under the overturning moment, which can easily lead to the stripping of the teeth between the ratchet and the rack, posing a risk of falling off.

[0004] In view of the above, it is necessary to propose an integrated locking and guiding device for a water tank lifting platform to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to overcome the defects in the existing technology and provide a locking and guiding integrated device for a water tank lifting platform.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows: A locking and guiding integrated device for a water tank lifting platform, comprising:

[0007] The guide groove is a guiding mechanism for the vertical movement of the lifting platform;

[0008] The sliding shoe is slidably installed in the guide groove and moves up and down to adjust its position. The sliding shoe is connected to the lifting platform to form a supporting foundation for the lifting platform.

[0009] The locking structure includes a locking rack disposed in a guide groove and a locking tooth disposed on a slip shoe. The locking tooth is L-shaped and includes a transversely arranged lever arm and a longitudinally arranged locking tooth rod. The connection end between the lever arm and the locking tooth rod is a rotating part. The locking tooth is rotatably disposed on the slip shoe with the rotating part. The locking structure rotates in a controlled manner on the slip shoe, so that the end of the locking tooth rod engages with the locking rack, and the pressure direction of the slip shoe on the locking tooth rod is close to the length direction of the locking tooth rod.

[0010] Furthermore, the slip shoe has an inner cavity for mounting pulleys, and the top of the inner cavity is an opening for the cable to enter the inner cavity and be wound around the pulleys to provide lifting power.

[0011] Furthermore, the outer side of the slipper is provided with a guide roller structure, which includes side guide rollers disposed on both sides of the slipper and bottom guide rollers disposed at the bottom of the guide groove.

[0012] Furthermore, the slipper is equipped with a drive cylinder, one end of which is hinged to the slipper, and the free end of which is hinged to the end of the lever arm.

[0013] Furthermore, the lever arm and the locking tooth rod of the locking tooth member are an integral fixed structure, so that the lever arm and the locking tooth rod form a lever structure, and the lever arm is longer than the locking tooth rod.

[0014] Furthermore, the rotating part includes a hinge base and a hinge shaft. The hinge base is provided with a hinge shaft. The ends of the lever arm and the locking tooth rod are rotatably mounted on the hinge shaft to form a rotatable connection. The hinge shaft is provided with an elastic element. The elastic element is configured to ensure that the free end of the locking tooth rod always has a tendency to rotate and engage with the locking rack.

[0015] Furthermore, the end of the lever arm away from the hinge axis is the driving end, and a coupling structure is provided between the hinge end of the lever arm and the toothed rod to limit the rotation angle and travel of the toothed rod or to drive the toothed rod to rotate.

[0016] Furthermore, the coupling structure includes an arc-shaped groove and a protruding rod. One of the lever arm rod and the locking tooth rod is fixedly provided with a protruding rod at its end, while the other is provided with an arc-shaped groove, and the protruding rod is inserted into the arc-shaped groove.

[0017] Furthermore, the side guide roller is provided with lateral supports on both sides of the slipper, and lateral rollers are rotatably mounted on the lateral supports; the bottom guide roller includes a bottom support set near the bottom of the guide groove of the slipper, and a bottom roller is rotatably mounted on the bottom support, and the lateral rollers and the bottom rollers are both rolledly connected to the inner wall of the guide groove.

[0018] The advantages and beneficial effects of this utility model are as follows: This utility model provides an integrated locking and guiding device for a water tank lifting platform. By passing a cable around a pulley and connecting to a winch, the platform can be raised and lowered, providing power and facilitating control of its height. In this device, the locking rod is longitudinally engaged with the rack, providing optimal support for the lifting platform and effectively preventing overturning torque from acting on the locking rod. Furthermore, by utilizing the coupling control between the lever arm and the locking rod, the rotation angle of the locking rod can be limited, its position fixed, or it can be driven to move, thus realizing multiple control functions of the lever arm on the locking rod and achieving different effects.

[0026] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0027] Example 1:

[0028] Existing products do not all have locking and guiding devices; they usually have only one of these functions, and there are basically no products that integrate both devices. Most products with locking devices use pin-type locking, as shown in the patent technology in the background. This requires high installation and manufacturing precision and is not conducive to achieving automatic synchronous locking. Manual intervention or direct insertion of the pin is required during the locking process.

[0029] This embodiment discloses an integrated locking and guiding device for a water tank lifting platform, such as... Figure 1 As shown, it includes a guide groove 1, which is a guide mechanism for the lifting platform to move up and down; in actual use, several sets of this device are set on the four side walls of the pool, and multiple guide grooves 1 are vertically set around the pool. Each guide groove 1 is used to guide the lifting of the platform, restrict the lateral movement of the platform, and support the platform through the guide groove 1.

[0030] Slipper 2, such as Figure 2 , 5 As shown, the sliding shoe 2 is slidably set in the guide groove 1 and slides up and down to adjust its position. The sliding shoe 2 is connected to the lifting platform to form a supporting foundation for the lifting platform. In the figure, the sliding shoe 2 has an installation platform that extends out of the side opening of the guide groove 1. The platform bracket 22 is fixedly set on the installation platform. Then, each sliding shoe 2 of each locking and guiding integrated device can form a supporting foundation around the platform. By controlling the lifting and locking position of the sliding shoe 2 in the guide groove 1, the platform can be controlled to lift or position.

[0031] The locking structure includes a locking rack 3 disposed in the guide groove 1 and a locking tooth 4 disposed on the slipper 2. The locking tooth 4 is L-shaped. In this embodiment, to improve the support stability of the locking structure, the locking tooth 4 is designed as an L-shape, including a laterally arranged lever arm 5 and a longitudinally arranged locking tooth 6, such as... Figure 3As shown, the lever arm 5 and the locking tooth rod 6 of the locking tooth member 4 are integrally fixed structures, and the lever arm 5 and the locking tooth rod 6 form a lever structure, wherein the lever arm 5 is longer than the locking tooth rod 6. The sliding shoe 2 is equipped with a drive cylinder 11, as shown in the figure. The drive cylinder 11 can be an electric drive cylinder 11 or a hydraulic drive cylinder 11. One upper end of the drive cylinder 11 is rotatably mounted on the side wall of the sliding shoe 2 away from the guide groove 1 via a hinged lug, and its lower end is a free end, which is hinged to the end of the lever arm 5. This forms an extended lever arm 5 to drive the locking tooth rod 6 to rotate.

[0032] In actual use, a rotating part 7 for mounting the locking gear 4 is provided on the side of the sliding shoe 2 near the locking rack 3. Specifically, the rotating part 7 consists of a fixed hinge base 12, with two hinge base 12 supports supporting a hinge shaft 13. The corner position of the locking gear 4 is rotatably set on the hinge shaft 13, thus forming a structure in which the locking gear 4 is rotatably set on the sliding shoe 2 by the rotating part 7. The locking structure is then controlled to rotate on the sliding shoe 2, specifically by the extension and retraction of the free end of the drive cylinder 11, which controls the up and down movement of the drive end 15 of the control lever 5, thereby controlling the locking rod 6 to engage or disengage from the locking rack 3. When the end of the locking rod 6 engages with the locking rack 3, the position of the lifting platform can be locked. In this embodiment, since the locking tooth 4 is L-shaped, the pressure direction of the slipper 2 acting on the locking tooth 6 is close to the length direction of the locking tooth 6. In this embodiment, when the platform is locked, the weight of the platform acts on the slipper 2, and the rotating part 7 applies downward pressure to the locking tooth 6. In this embodiment, when locked, the overall position of the locking tooth 6 is basically longitudinal, which is basically coincident with the direction of the pressure applied to it. This allows the locking tooth 6 to provide high support performance and can effectively prevent it from deflecting under the action of gravity. Compared with the patented technology in the background art, the force direction of the transversely arranged ratchet structure is perpendicular to it, which is extremely easy to cause rotation and easily leads to the danger of slippage.

[0033] Furthermore, the sliding shoe 2 has an inner cavity for mounting the pulley 8, and the top of the inner cavity is an opening for the cable to enter the inner cavity and be wound around the pulley 8 to provide lifting power. Figure 1-3 As shown, each guide groove 1 has an internal hollow design, which allows the winch cable to enter and connect to the pulley 8 inside the slipper 2. The slipper 2 is then raised and lowered by pulling the winch and cable.

[0034] Furthermore, to make the sliding shoe 2 more stable during lifting and lowering and reduce lateral displacement, a guide roller structure is provided on the outer side of the sliding shoe 2. Specifically, the guide roller structure includes side guide rollers 9 arranged on both sides of the sliding shoe 2 and bottom guide rollers 10 arranged at the bottom of the guide groove 1. The side guide rollers 9 are provided with lateral supports 18 on both sides of the sliding shoe 2, and lateral rollers 19 are rotatably mounted on the lateral supports 18; the lateral rollers 19 are respectively attached to the inner walls on both sides of the guide groove 1; similarly, the bottom guide roller 10 includes a bottom support 20 arranged near the bottom of the guide groove 1, such as... Figure 2-4 As shown, the bottom support is provided at both the upper and lower ends of the slipper 2. The bottom support 20 is rotatably equipped with a bottom roller 21. The side roller 19 and the bottom roller 21 are both rolledly connected to the inner wall of the guide groove 1, which makes the up-and-down movement of the slipper 2 more stable.

[0035] Example 2:

[0036] In this embodiment, the structure is basically the same as in Embodiment 1, except that the lever arm 5 and the toothed lever 6 are two independent parts, such as... Figure 5 , 6 As shown, the ends of the lever arm 5 and the locking tooth 6 are rotatably mounted on the hinge shaft 13, forming a rotatable connection. This allows the lever arm 5 and the locking tooth 6 to rotate independently on the hinge shaft 13. An elastic element 14 is provided on the hinge shaft 13, and the elastic element 14 is configured to ensure that the free end of the locking tooth 6 always tends to rotate and engage with the locking rack 3. Under the action of the elastic element 14, an automatic locking function can be achieved. That is, no matter what position the cable pulls the platform to, the elastic element 14 always applies a spring force to cause the end of the locking tooth 6 to rotate and engage with the locking rack 3, which can improve the safety of the platform and avoid the danger of the platform slipping due to forgetting to lock.

[0037] Furthermore, since the lever arm 5 and the locking tooth 6 are independent parts, the locking or unlocking of the locking tooth 6 needs to be controlled by the lever arm 5, and a certain range of free rotation locking margin needs to be provided for the locking tooth 6. To solve this problem, this embodiment provides a coupling structure. Specifically, the end of the lever arm 5 away from the hinge shaft 13 is the driving end 15. A coupling structure is provided between the hinge end of the lever arm 5 and the locking tooth 6 to limit the rotation angle stroke of the locking tooth 6 or to drive the locking tooth 6 to rotate.

[0038] like Figure 5 , 6As shown, the coupling structure includes an arc groove 16 and a protruding rod 17. One of the lever arm rod 5 and the toothed rod 6 is fixedly provided with a protruding rod 17 at its end, while the other is provided with an arc groove 16. The protruding rod 17 is inserted into the arc groove 16. This embodiment takes the example of setting a protruding rod 17 on the lever arm 5 and setting an arc-shaped groove 16 on the locking rod 6. Due to the setting of the arc-shaped groove 16, the locking rod 6 is allowed to rotate freely within the angle range of the arc-shaped groove 16. It can be understood that the rotation range of the arc-shaped groove 16 corresponds to the range of motion where the locking rod 6 can be freely locked. When it is necessary to manually control the locking rod 6 to unlock, the specific operation is as follows: by retracting the free end of the drive cylinder 11, the drive end 15 of the lever arm 5 is pulled upward, and the protruding rod 17 also moves upward. When the protruding rod 17 touches the upper stop point of the arc-shaped groove 16, the locking rod 6 can be controlled to rotate together with the lever arm 5. As the rotation proceeds, the lower end of the locking rod 6 can leave the locking rack 3. At this time, the rise or fall of the platform can be controlled by winding the cable.

[0039] When this locking structure is needed to lock the position, it is necessary to control the free end of the drive cylinder 11 to extend a certain distance, so that the convex rod 17 moves to the middle of the arc groove 16, and the locking tooth rod 6 can rotate freely within a certain angle range. At this time, under the action of the elastic element 14, the locking structure can achieve free locking during the upward process.

[0040] In another application scenario, such as when the platform position and height are already determined and a safety measure is needed to prevent the locking rod 6 from coming loose, the free end of the drive cylinder 11 can be controlled to extend downwards a certain distance, and then the protrusion 17 can be locked at the lower stop point of the arc groove 16, thereby restricting the reverse rotation of the locking rod 6 and preventing the lower end of the locking rod 6 from rotating away from the locking rack 3, thus achieving the effect of safety locking.

[0041] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
