Description

Technical Field

[0001] The invention relates to the field of lifting equipment, and in particular to an integrated locking and guiding device for a pool lifting platform. Background Art

[0002] The retracting and releasing system of the water pool lifting platform mainly uses steel wire ropes to control and drive the platform up and down. In order to ensure the smoothness of the up and down lifting process, a guide structure is required to limit its horizontal movement; at the same time, in order to ensure that the platform can stop safely and smoothly at the desired position when it stops, a locking device is required to achieve this function. Moreover, because the retracting and releasing system of the water pool lifting platform realizes cross-domain lifting between water and underwater, the operation of the locking device cannot be realized by observation, so the locking of the platform can only be achieved through automatic operation. In addition, the platform is relatively large, and multiple locking devices are required to ensure effective and smooth locking, which requires the synchronous operation of multiple locking devices. At present, there are many types of lifting platform products, mainly including land climbing platforms, lifting platforms, water lifting platforms, ship lifting platforms, etc. The main driving modes of these lifting platforms are wire rope drive, scissor-type cylinder drive, cylinder direct drive, gear rack drive, pin-type cylinder drive, etc. Some of them have locking devices and some do not, some have guide devices and some do not, and there is basically no integration of these two devices, and most of the locking devices use pin-type locking.

[0003] For example, patent application number: CN201911202150.X discloses a lifting platform. A locking device for a lifting platform includes: a base, a rack and a locking mechanism; the base is used to provide support for the lifting of the lifting platform; the rack is longitudinally installed on one side of the base; the locking mechanism is fixedly connected to the lifting platform, and the locking mechanism rises and falls along the base with the lifting platform; the locking mechanism includes: a ratchet structure; the ratchet structure cooperates with the rack, when the ratchet structure is engaged with the rack, the lifting platform is locked, and when the ratchet structure is disengaged from the rack, the lifting platform is unlocked. The defect is that this patented technology uses the lateral extension and movement of the ratchet structure to fit into the rack to fix the position of the platform. Since the lifting platforms used in the shipbuilding industry are usually heavily loaded, the ratchet structure in this technology extends and moves horizontally. When the upper side of the platform is subjected to force, the gravity acts vertically on the ratchet structure set in a horizontal state. During actual use, the tooth ends are engaged and fixed, and under the action of gravity, a capsizing moment with a rotational motion tendency with the tooth ends as the center is formed. In addition, in order to make the ratchet structure more flexible, sufficient clearance must be left around it and between the sliding sleeve, so that the ratchet structure is more likely to rotate under the capsizing moment, which can easily lead to slippage between the ratchet and the rack, and there is a risk of falling.

[0004] In view of the above, it is necessary to propose a locking and guiding integrated device for a pool lifting platform to solve the above problems. Summary of the invention

[0005] The purpose of the present invention is to overcome the defects in the prior art and provide a locking and guiding integrated device for a pool lifting platform.

DETAILED DESCRIPTION

[0017] The specific implementation of the present invention is further described below in conjunction with the accompanying drawings and embodiments. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and cannot be used to limit the protection scope of the present invention. Embodiment 1

[0018] Not all existing products have locking and guiding devices, usually they only have one of the functions, and there is basically no product that integrates these two devices into one. Most of the products with locking devices use latch-type locking, as shown in the patent technology in the background technology, which has relatively high requirements for installation and manufacturing precision, and is not conducive to achieving automatic synchronous locking. Manual intervention or direct insertion of the latch is required during the locking process.

[0019] This embodiment discloses a locking and guiding integrated device for a pool lifting platform. 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 groups of this device are arranged on the side walls around the pool, and multiple guide grooves 1 are vertically arranged around the pool, each guide groove 1 is used to guide the lifting of the platform, limit the lateral movement of the platform, and support the platform through the guide groove 1.

[0020] Slippers 2, such as Figure 2 , 5 As shown, it is slidably arranged in the guide groove 1 and slides up and down to adjust the position, and the sliding shoe 2 is connected to the lifting platform to form a supporting base for the lifting platform; in the figure, one side of the sliding shoe 2 is provided with a mounting platform extending out of the side opening of the guide groove 1, and the platform bracket 22 is fixedly arranged on the mounting platform, and then each sliding shoe 2 of each locking and guiding integrated device can form a supporting base around the platform, and the lifting or positioning of the platform can be controlled by controlling the lifting and locking position of the sliding shoe 2 in the guide groove 1.

[0021] The locking structure includes a locking rack 3 arranged in the guide groove 1, and a locking toothed member 4 arranged on the sliding shoe 2. The locking toothed member 4 is L-shaped. In this embodiment, in order to improve the supporting stability of the locking structure, the locking toothed member 4 is designed to be L-shaped and includes a force arm rod 5 arranged horizontally and a locking toothed rod 6 arranged longitudinally. Figure 3 As shown, the lever arm 5 and the latching tooth rod 6 of the locking toothed member 4 are an integrated fixed structure, and the lever arm 5 and the latching tooth rod 6 form a lever structure, and the lever arm 5 is longer than the latching tooth rod 6. The sliding shoe 2 is provided with a driving cylinder 11, as shown in the figure, the driving cylinder 11 can be an electric driving cylinder 11 or a hydraulic driving cylinder 11, and the upper end of the driving cylinder 11 is rotatably mounted on the side wall of the sliding shoe 2 away from the guide groove 1 in the form of a hinged ear seat, and the lower end is a free end, and the free end of the driving cylinder 11 is hinged to the end of the lever arm 5. Thus, an extended lever arm 5 is formed to drive the latching tooth rod 6 to rotate.

[0022] In actual use, a rotating part 7 for mounting the locking toothed member 4 is provided on the side of the sliding shoe 2 close to the locking rack 3. Specifically, the rotating part 7 is composed of a fixed hinged base 12, and two hinged base 12 brackets are provided with a hinge shaft 13. The locking toothed member 4 is rotated and set on the hinge shaft 13 at the rotational position, that is, a structure is formed in which the locking toothed member 4 is rotated and set on the sliding shoe 2 by the rotating part 7; and then the locking structure is controlled to rotate on the sliding shoe 2, specifically, the free end of the driving cylinder 11 is telescopically moved, and the driving end 15 of the lever arm 5 is controlled to move up and down, and then the latching tooth rod 6 is controlled to be clamped into or leave the locking rack 3. When the end of the latching tooth rod 6 is clamped into the locking rack 3, the position of the lifting platform can be locked. In the present embodiment, since the locking tooth 4 forms an L shape, the direction of the pressure exerted by the sliding shoe 2 on the latching gear rod 6 is close to the length direction of the latching gear rod 6. In the present embodiment, when the platform is in the locking position, the gravity of the platform acts on the sliding shoe 2, and the downward pressure is applied to the latching gear rod 6 through the rotating part 7. When the present embodiment is in the locking position, the overall position of the latching gear rod 6 is basically arranged in the longitudinal direction, which basically coincides with the direction of the pressure applied thereto, so that the latching gear rod 6 can provide higher supporting performance and can well avoid its deflection under the action of gravity; compared with the patented technology in the background technology, the force direction of the ratchet structure arranged laterally is perpendicular to it, which is extremely easy to cause rotation and easily cause the risk of slipping teeth.

[0023] Furthermore, the inner cavity of the sliding shoe 2 is formed to install 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 is designed to be hollow inside, which can facilitate the entry of the winch cable and connect to the pulley 8 in the sliding shoe 2. The winch and cable pull the sliding shoe 2 to perform lifting and lowering control.

[0024] Furthermore, in order to make the sliding shoe 2 more stable during the lifting process and reduce the lateral displacement, a guide roller structure is provided on the outside of the sliding shoe 2. Specifically, the guide roller structure includes side guide rollers 9 provided on both sides of the sliding shoe 2 and a groove bottom guide roller 10 provided at the groove bottom of the guide groove 1. The side guide rollers 9 are provided with lateral brackets 18 on both sides of the sliding shoe 2, and lateral rollers 19 are rotatably provided on the lateral brackets 18; the lateral rollers 19 are respectively attached to the inner walls of the two sides of the guide groove 1; similarly, the groove bottom guide roller 10 includes a groove bottom bracket 20 provided near the inner groove bottom of the guide groove 1 of the sliding shoe 2, as shown in FIG. Figure 2-4 As shown, the groove bottom frame is arranged at the upper and lower ends of the sliding shoe 2, and the groove bottom roller 21 is rotatably provided on the groove bottom bracket 20. The lateral roller 19 and the groove bottom roller 21 are both rollingly connected to the inner wall of the guide groove 1, thereby making the up and down lifting of the sliding shoe 2 more stable. Embodiment 2

[0025] In this embodiment, the structure is basically the same as that of the first embodiment, except that the lever arm 5 and the latching gear rod 6 are two independent parts. Figure 5 , 6 As shown, the ends of the lever arm 5 and the latching gear rod 6 are both rotatably arranged on the hinge shaft 13 to form a rotatable connection, so that the lever arm 5 and the latching gear rod 6 can be independently rotated on the hinge shaft 13, and an elastic member 14 is arranged on the hinge shaft 13, and the elastic member 14 is arranged to make the free end of the latching gear rod 6 always have a tendency to rotate and snap into the locking rack 3. Under the action of the elastic member 14, the automatic locking function can be realized, that is, no matter where the cable pulls the platform to rise, the elastic member 14 always applies elastic force to make the end of the latching gear rod 6 rotate and snap into 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.

[0026] Furthermore, since the lever arm 5 and the tooth rod 6 are independent parts, the locking or unlocking of the tooth rod 6 must be controlled by the lever arm 5, and a certain range of free rotation locking margin must be provided to the tooth rod 6. To solve this problem, a coupling structure is provided in the present embodiment. Specifically, the end of the lever arm 5 away from the hinge shaft 13 is the driving end 15, and a coupling structure is provided between the hinge end of the lever arm 5 and the tooth rod 6 for limiting the rotation angle travel of the tooth rod 6 or driving the tooth rod 6 to rotate.

[0027] like Figure 5 , 6 As shown, the coupling structure includes an arc groove 16 and a protruding rod 17 . One of the arm rod 5 and the latching gear rod 6 is fixedly provided with a protruding rod 17 at its end, and the other is provided with an arc groove 16 , and the protruding rod 17 is inserted into the arc groove 16 . In this embodiment, a convex rod 17 is set on the force arm rod 5 and an arc groove 16 is set on the latch gear rod 6 as an example. Due to the setting of the arc groove 16, the latch gear rod 6 is allowed to rotate freely within the angle range of the arc groove 16. It can be understood that the rotation range of the arc groove 16 corresponds to the range of movement in which the latch gear rod 6 can be freely locked; when it is necessary to manually control the latch gear rod 6 to unlock, the specific operation is to pull the driving end 15 of the force arm rod 5 upward by contracting the free end of the driving cylinder 11, so that the convex rod 17 also moves upward. When the convex rod 17 touches the upper end stop point of the arc groove 16, the latch gear rod 6 can be controlled to rotate together with the force arm rod 5. As the rotation proceeds, the lower end of the latch gear rod 6 can leave the locking rack 3. At this time, the rise or fall of the platform can be controlled by winding up the cable.

[0028] When the 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 protruding rod 17 moves to the middle of the arc groove 16, and the tooth rod 6 can rotate freely within a certain angle range. At this time, under the action of the elastic member 14, the locking structure can achieve free locking during the rising process.

[0029] In another application scenario, for example, when the platform position height has been determined and a safety is needed to prevent the latching gear rod 6 from loosening, in this application, the free end of the drive cylinder 11 can be controlled to continue to extend downward for a certain distance, and then the protruding rod 17 can be stuck at the lower dead point of the arc groove 16, thereby limiting the reverse rotation of the latching gear rod 6, thereby preventing the lower end of the latching gear rod 6 from rotating away from the locking rack 3, thereby achieving the effect of safety locking.

[0030] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
