Description
Technical Field
[0001] The utility model relates to the technical field of elevators, in particular to a guide mechanism for an elevator door sill and an elevator door sill. Background Art
[0002] With the rapid development of society, elevators have become a common special equipment for us, and the safety of elevators has become increasingly important. Below the entrance and exit of a cabin elevator, there are usually sills on the hall door side and the car door side to fill the gap between the elevator shaft and the ground to prevent passengers or objects from falling into the elevator shaft through the gap. At the same time, the elevator door sill is also provided with a guide groove that cooperates with the door guide shoe on the elevator door to achieve the sliding opening and closing of the elevator hall door. In the prior art, the guide groove of the elevator door sill is set on the upper surface of the sill, with the opening facing upward, and cooperates with the door guide shoe plate set on the door panel, so that the door panel can only move in a limited direction.
[0003] Since the guide groove of the elevator door sill opens upward and there is no structure to limit the upward movement of the door guide shoe, when the elevator door panel is subjected to a certain impact force, there is a problem that the bottom of the door guide shoe plate will be lifted up and move upward from the guide groove and slide out, thereby causing the risk of the elevator door loosening and falling. Therefore, the prior art adds a hook to the guide groove of the elevator door sill and the door guide shoe plate to prevent the door guide shoe from lifting up and causing the elevator door to loosen, and solves the problem that the lower part of the door panel is caused to fall out of the guide groove due to external force impact.
[0004] However, the current sills still have the problem that sand, dust, hair, fiber fabrics and other debris are easily accumulated on the guide groove. This problem may increase the resistance of door opening and closing, affecting the service life of the door machine, or even cause door opening and closing failures, people trapped in the elevator, etc. The addition of hooks on the sill guide groove and the door guide shoe plate further aggravates the problem of debris accumulation in the guide groove, causing door opening and closing failures and people trapped in the elevator. Therefore, it is necessary to design an elevator door sill guide mechanism that can prevent debris from accumulating in the guide groove, so as to prevent safety accidents such as door opening and closing failures and people trapped in the elevator.

[0024] The utility model is further described in detail below in conjunction with the accompanying drawings and embodiments.
[0025] Example 1
[0026] The guide mechanism of the elevator door sill of the utility model is installed under the elevator sill. Figure 1 , which is a structural schematic diagram of an elevator door sill guide mechanism and an elevator door sill in Example 1 of the utility model. The guide mechanism includes: a guide plate 10, a guide shoe plate 20, and a slider 30. The guide plate 10 is fixed below the elevator sill panel 1 and is located within the orthographic projection of the upper surface of the elevator door sill; the upper part of the guide shoe plate 20 is fixed to the bottom of the elevator door panel 4, and the lower part is fixed with a slider 30; the slider 30 is slidably matched with the guide plate 10, so that the moving direction of the elevator door panel 4 is limited to the extension direction of the guide plate 10.
[0027] Specifically, the guide plate 10 includes a fixing portion 11 and a guide rail 12. The fixing portion 11 is fixed on both sides of the elevator sill panel 1 and the sill bottom plate 3, respectively, and is located between the two. The guide rail 12 is fixed below the elevator sill panel through the fixing portion 11. Specifically, the fixing portion 11 includes two parallel plates parallel to each other and a support plate supported between the two parallel plates. Preferably, the support plate is perpendicular to the parallel plates. The two parallel plates are respectively arranged parallel to the elevator sill panel 1 and the elevator sill bottom plate 3 and are tightly fitted and fixed. The support plate of the fixing portion 11 forms an approximately rectangular structure with the sill panel 1 and the sill bottom plate 3, so that the fixing portion 11 and the sill panel 1 and the sill bottom plate 3 support each other, which has the effect of increasing the strength and stability of the elevator floor door sill. The fixing connection method can be bolt connection, riveting, bonding, welding and other connection methods. The guide rail 12 is formed by extending downward from the parallel plate fixed by the fixing portion 11 below the elevator sill panel. The guide plate 10 has a simple structure and can be formed by bending metal or polymer materials in one piece during processing.
[0028] The upper part of the guide shoe plate 20 is fixed on one side of the elevator door panel, and has a bending structure for avoiding the elevator floor door sill. The shape of the bending structure fits the shape of the outer contour of the elevator hall door and the sill. Specifically, the bending structure includes a vertical section that is close to the side of the elevator hall door, a parallel section arranged parallel to the elevator sill panel, and an extension section parallel to the extension direction of the end of the sill panel; the vertical section and the parallel section, and the parallel section and the extension section are connected by a smooth arc section. The setting of the bending structure makes the elevator door sill guide mechanism more compact, which can prevent the guide shoe plate 20 from colliding with foreign objects falling into the elevator or other components of the elevator during the operation of the elevator and being damaged. The fixed connection method of the guide shoe plate 20 and the elevator door panel can be bolted, riveted, bonded, welded, etc., preferably bolted. The lower part of the guide shoe plate 20 is provided with a slide plate 21, which is formed by extending the extension section of the bending structure and is used to support the slider 30. The inner wall of the slide plate 21 is bonded to one side and the bottom of the slider 30. Furthermore, the slide slot plate 21 at the lower part of the guide shoe plate 20 extends an anti-slip plate 22 to the other side of the slider 30, and the slide slot plate 21 and the anti-slip plate 22 form an anti-slip hook. The anti-slip hook is used to accommodate and fix the slider 30, which can prevent the bottom of the door guide shoe plate from tilting up and sliding out of the guide slot after the door panel is impacted by external force. In addition, since the anti-slip hook is located below the sill panel 1, the dust falling in the environment will not fall into the anti-slip hook under the blocking effect of the sill panel 1, so that good working stability can be maintained.
[0029] The slider 30 includes a groove side wall 31 and a groove bottom 32, and the groove side wall 31 and the groove bottom 32 form a groove that cooperates with the guide rail 11, so that the slider 30 can slide along the extension direction of the guide rail 11. The groove side wall 31 is tightly connected to both sides of the guide rail 11 to ensure that the slider 30 is limited on the guide rail 11. The slider 30 is made of elastic material, preferably a polymer material with self-lubricating properties. Since the slider 30 is made of elastic material, the slider 30 can effectively absorb the vibration and noise during the opening and closing process of the elevator door, making the elevator door move more gently when starting and stopping, avoiding the discomfort and potential mechanical damage caused by severe impact. In addition, the slider 30 made of elastic material also has the advantage of easy installation. During installation, the installer can squeeze the slider 30 to reduce its volume, thereby easily installing the slider 30 on the guide shoe plate 20; after the installation is completed, the slider 30 restores its original size under the action of elasticity and has a squeezing effect on the guide shoe plate 20, so the slider 30 can be tightly clamped on the guide shoe plate 20 to prevent the slider 30 from loosening and falling off the guide shoe plate 20.
[0030] Furthermore, the technicians found that when using the guide mechanism of the elevator door sill, the elevator door panel is prone to shaking, sliding unsmoothly and other problems. After careful inspection, the technicians found that due to the limitations of the existing one-piece molding process, the end of the guide rail 12 is relatively sharp. When the slider 30 slides on the guide rail 12, its groove bottom 32 is easy to scratch the sharp end of the guide rail 12, causing the slider 30 to be damaged and unable to be stably fixed on the guide rail 12, resulting in the elevator door panel shaking or being stuck on the guide rail 12 and unable to move normally. Therefore, the present application further improves the groove bottom 32 so that the width of the groove bottom 32 is greater than the width of the guide rail 12 to avoid the sharp end of the guide rail 12 from scratching the groove bottom 32, and at the same time, it can more conveniently fix the slider 30 to the anti-slip hook at the bottom of the guide shoe plate 20. The groove bottom width of the groove is W, and the width of the guide rail is w. Preferably, w<W≤5w. Furthermore, the groove side wall 31 and the groove bottom 32 are connected in an arc shape to reduce the internal stress of the slider 30 and extend the service life of the slider 30 .
[0031] The working principle of the elevator door sill guide mechanism of the utility model is as follows: when the elevator door control system controls the elevator door panel 4 to open and close, the guide rail 12 and the slider 30 fixed to the guide shoe plate 20 are nested and cooperated with each other, guiding the elevator door panel 4 to make smooth and stable linear motion along the direction in which the guide rail 10 extends, thereby playing a role of limiting and guiding the elevator door panel 4.
[0032] Example 2
[0033] See also Figure 1 , this embodiment provides an elevator door sill. The elevator door sill includes the guide mechanism of the elevator door sill of embodiment 1, the sill panel 1 and the sill bottom plate 3, and the guide mechanism of the elevator door sill of embodiment 1 is fixed between the sill panel 1 and the sill bottom plate 3. Since the guide mechanism is arranged below the sill panel 1, the upper surface of the sill panel 1 no longer needs to be provided with a traditional guide rail structure, so the sill panel 1 is flush with the elevator car floor and the elevator hall floor. Since the upper surface of the sill panel 1 is relatively flat, it is not easy to accumulate sand, gravel, hair and other debris, so it is helpful to prevent door opening and closing failures and safety accidents of people being trapped in the elevator, and ensure the safety of the elevator during use; at the same time, the flat sill surface facilitates cleaning work for cleaning personnel; it can also prevent users from being tripped by the elevator door sill; in addition, it also has aesthetics.
[0034] Furthermore, the surface of the sill panel 1 is provided with an anti-skid groove. The bottom of the anti-skid groove is slightly sunken compared to the upper surface of the sill panel, so that a large amount of sand and other debris will not accumulate; even if dust is hidden, it will not increase the difficulty of cleaning because the anti-skid groove is shallow.
[0035] The sill bottom plate 3 supports the sill panel 1 and the guide mechanism of the elevator door sill, and forms a rectangular structure with the sill panel 1, and the rectangular structure is provided with an opening; the slider 30 is located at the opening position of the sill bottom plate 3. In this embodiment, the bottom surface of the sill bottom plate 3 extends upward toward the opening position, which is conducive to enhancing the supporting function of the sill bottom plate. In addition, the door sill height of this embodiment is relatively low, which can meet the thickness requirements of the car floor on the car door side.
[0036] See also Figure 2 In some embodiments, the bottom surface of the sill bottom plate 3 extends downward toward the opening position to form a stepped structure. The stepped structure can be used to enhance the supporting effect of the sill bottom plate 3 and reduce the amount of material required for the sill bottom plate 3 and the guide plate 10 to save costs.
[0037] See also Figure 3 In some embodiments, the bottom surface of the sill bottom plate 3 extends downward toward the opening position to form a multi-step structure, forming different heights of the elevator door sills to meet the requirements of the ground thickness of different hall layers and the thickness of the bottom of the car.
[0038] Compared with the prior art, the guide mechanism of the elevator door sill of the utility model achieves the technical effect of preventing debris from accumulating in the guide groove by setting the guide rail under the sill panel and coordinating the guide shoe plate and the slider; further, the structure of the slider groove bottom and the hook structure of the fixed slider are cleverly set to increase the service life and stability of the guide mechanism; the upper surface of the elevator door sill using the guide mechanism of the application is flat and not easy to accumulate sand and stones, ensuring the safety of elevator use, and also having the advantages of convenient cleaning, beautiful and practical. The guide mechanism and elevator door sill of the application also have the advantages of simple structure, easy installation and low cost.
[0039] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, and the utility model is also intended to include these modifications and modifications.
