Description

Technical Field

[0001] This utility model belongs to the field of elevator installation technology, specifically relating to an elevator sill anti-detachment component. Background Technology

[0002] An elevator sill is a grooved metal step used for entering and exiting the elevator car or landing door. It has load-bearing capacity and is used to ensure the safe operation of the elevator. According to relevant regulations, each landing entrance should be equipped with a sill of sufficient strength to withstand the load of people entering the car.

[0003] Domestic utility model patent application number 202421274021.8 discloses an anti-detachment elevator sill structure, belonging to the field of elevator sill technology. It mainly solves the problem that in existing sill structures, where a sill groove for sliding blocks is provided, dust and foreign objects easily accumulate in the groove during use. If these impurities are not cleaned in time, the elevator door may become stuck, and in severe cases, the sliding block may detach from the sill. The solution involves setting up a sill bracket, with a front connecting plate and a rear connecting plate fixedly connected to the top of the bracket, and a supporting beam fixedly connected to the bottom. The bracket has a guide groove inside, with multiple sliders slidably installed inside. A door is located above the bracket. Anti-detachment protrusions are fixedly connected to the surfaces of the front and rear connecting plates that are close to each other. Each anti-detachment protrusion has an inclined surface at its top, and a receiving groove is provided between the two anti-detachment protrusions. Fixing plates are installed on the surfaces of the two sets of sliders that are close to each other, and cleaning cotton is provided at the edges of the fixing plates. The aforementioned utility model reduces the accumulation of dust and foreign objects in the sill groove and cleans impurities in a timely manner, avoiding the situation where the elevator door gets stuck due to dust and foreign objects, and in severe cases, the sliding block detaches from the sill structure. However, in actual use, the operation of the elevator door is controlled by sensors, and the elevator is regularly cleaned by maintenance personnel. When the sill is subjected to pressure for a long time or when the elevator guide has problems and shakes, it is very easy to cause impact and compression to the elevator shaft wall, thereby causing the sill to detach. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides an elevator sill anti-detachment component, including an elevator car floor. Anti-detachment components are fixedly installed on both sides of the top of the elevator car floor, and a sill component is fixedly installed on the top of the anti-detachment components. The sill component and the elevator car floor are connected and installed through a support frame. A positioning part is provided on the sill component at the position of the anti-detachment component. A limit block is welded and installed on the anti-detachment component, and a bearing block is connected and installed on the top of the limit block. A shock-absorbing spring that is limited and fixed by the positioning part is welded and installed on the bearing block.

[0005] As a further preferred technical solution of this utility model, a connecting block that cooperates with one side of the limiting block is welded and installed at the bottom of the positioning part, and the limiting block is provided with a pressing inclined surface that presses against the connecting block.

[0006] When the end of the sill is subjected to force and sinks, the sill will squeeze the anti-detachment component, causing the squeezing slope to squeeze the connecting block, thereby increasing the tightness of the connection between the sill and the elevator car floor.

[0007] As a further preferred technical solution of this utility model, an outer locking part and an inner locking part are welded and installed on the ground sill at both ends of the limiting block, and the outer locking part and the inner locking part are respectively locked and limited with the two sides of the limiting block. A bolt groove is provided on the anti-detachment component at the position of the inner locking part.

[0008] The outer and inner locking parts are respectively locked to the two sides of the limiting block to increase the tightness of the connection between the sill and the anti-detachment part. The anti-detachment part is fixed to the elevator car floor by expansion screws at the bolt groove position.

[0009] As a further preferred technical solution of this utility model; the top of the anti-detachment component is fixedly installed to the top of the elevator car floor by a mounting plate, the mounting plate is provided with a mounting slope, and the mounting slope is installed to the elevator car floor by an expansion screw, a pad is fixedly installed on the sill component at the top position of the mounting plate, and the pad is located at the top of the elevator car floor at one end of the mounting plate, and an auxiliary groove is provided on the bottom of the sill component inside the pad.

[0010] The anti-detachment component is fixed to the top of the elevator car floor using expansion screws. A mounting plate limits the position of the pad, ensuring the expansion screws are sealed within the auxiliary groove, reducing external friction and other stresses. Furthermore, the bottom of the sill is fitted and positioned flush with the anti-detachment component, guaranteeing the stability of the sill installation.

[0011] As a further preferred technical solution of this utility model; the top of the sill is provided with a fixing groove at the top of the anti-detachment component, and the top of the sill and the anti-detachment component are fixedly installed by a locking bolt passing through the fixing groove. The outer side of the sill is provided with an installation groove, and the installation groove and the anti-detachment component are fixedly installed by the locking bolt passing through the groove.

[0012] The sill and anti-detachment components are fixedly installed from different positions by two sets of locking bolts to ensure the stability of the installation between the sill and the anti-detachment components.

[0013] As a further preferred technical solution of this utility model; the support frame is located between the anti-detachment components, the top of the support frame is fixedly installed with the sill component by multiple sets of locking bolts, and the support frame is fixedly installed with the elevator car floor by multiple sets of butt bolts.

[0014] The anti-detachment component is fixedly installed to the elevator car floor, and the bottom of the sill component is fixedly installed to the support frame, which is also fixedly installed to the elevator car floor. The support frame provides load-bearing and fixing function for the sill component.

[0015] Beneficial effects

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] 1. During elevator use, the sill sinks under pressure, which over time can cause the connection between the sill and the elevator car to loosen, leading to sill detachment. When the end of the sill sinks under pressure, the sill compresses the anti-detachment component, causing the compression slope to press against the connecting block, increasing the tightness of the connection between the sill and the elevator car floor. The shock-absorbing springs installed between the load-bearing block and the positioning part can effectively reduce the sill from being severely deformed due to impact caused by the car shaking, which could result in the sill compressing the anti-detachment component or the elevator car floor.

[0018] 2. The anti-detachment component is fixedly installed to the elevator car floor. The bottom of the sill component is fixedly installed to the support frame, and the support frame is fixedly installed to the elevator car floor. The support frame provides load-bearing and fixing for the sill component, and the top of the sill component is fixedly positioned between it and the anti-detachment component. When the sill component is subjected to external force and detaches downward, it is stopped by the interlocking block to prevent direct detachment. Under force, the downward force compresses the anti-detachment component, and the shock-absorbing spring prevents the anti-detachment component from being deformed by compression. The compression slope compresses the connecting block, making the sill component and the elevator car floor tightly fitted together, reducing the possibility of the sill component detaching.

[0024] This specific embodiment is an elevator sill anti-detachment component.

[0025] The aforementioned utility model reduces the accumulation of dust and foreign objects in the sill groove and cleans impurities in a timely manner, avoiding the situation where the elevator door gets stuck due to dust and foreign objects, and in severe cases, the sliding block detaches from the sill structure. However, in actual use, the operation of the elevator door is controlled by sensors, and the elevator is regularly cleaned by maintenance personnel. When the sill is subjected to pressure for a long time or when the elevator guide has problems and shakes, it is very easy to cause impact and compression to the elevator shaft wall, thereby causing the sill to detach.

[0026] Its structural diagram is as follows Figures 1-4 As shown. An elevator sill anti-detachment component includes an elevator car floor 1. Anti-detachment components 3 are fixedly installed on both sides of the top of the elevator car floor 1. A sill component 2 is fixedly installed on the top of the anti-detachment components 3. The sill component 2 and the elevator car floor 1 are connected and installed together by a support frame 4. A positioning part 23 is provided on the sill component 2 at the position of the anti-detachment component 3. A limit block 32 is welded and installed on the anti-detachment component 3, and a bearing block 36 is connected and installed on the top of the limit block 32. A shock-absorbing spring 33 that is limited and fixed by the positioning part 23 is welded and installed on the bearing block 36. A connecting block 27 that cooperates with one side of the limit block 32 for limiting is installed at the bottom of the positioning part 23. The limit block 32 is provided with a pressing slope 35 that presses against the connecting block 27. During elevator use, the sill sinks under pressure, which over time can cause the connection between the sill and the elevator car to loosen, resulting in the sill detaching. When the end of the sill 2 sinks under pressure, the sill 2 compresses the anti-detachment component 3, causing the compression slope 35 to compress the connecting block 27, increasing the tightness of the connection between the sill 2 and the elevator car floor 1. The shock-absorbing spring 33 installed between the bearing block 36 and the positioning part 23 can effectively reduce the situation where the sill 2 is subjected to impact due to the shaking of the car, causing the sill 2 to be squeezed and severely deformed by the anti-detachment component 3 or the elevator car floor 1.

[0027] The sill 2 has an outer locking part 24 and an inner locking part 26 welded and installed at both ends of the limiting block 32. The outer locking part 24 and the inner locking part 26 are respectively locked and limited with the sides of the limiting block 32. The anti-detachment part 3 has a bolt groove 31 at the position of the inner locking part 26. By locking and limiting the sides of the limiting block 32 with the outer locking part 24 and the inner locking part 26 respectively, the fastening effect between the sill 2 and the anti-detachment part 3 is increased. The anti-detachment part 3 is fixedly installed to the elevator car floor 1 at the bolt groove 31 by expansion screws 342. The anti-detachment component 3 is fixedly installed to the top of the elevator car floor 1 via a mounting plate 34. The mounting plate 34 has a mounting bevel 341, and expansion screws 342 penetrate the mounting bevel 341 to connect it to the elevator car floor 1. A pad 21 is fixedly installed on the sill component 2 at the top of the mounting plate 34, with the pad 21 positioned at one end of the mounting plate 34 on the top of the elevator car floor 1. An auxiliary groove 22 is formed at the bottom of the sill component 2 inside the pad 21. The expansion screws 342 fix the top of the anti-detachment component 3 to the top of the elevator car floor 1. The mounting plate 34 limits the pad 21, ensuring the expansion screws 342 are sealed inside the auxiliary groove 22, reducing external friction and other forces. The bottom of the sill component 2 is fitted and positioned against the anti-detachment component 3, ensuring the stability of the sill component 2 installation. A fixing groove 28 is formed at the top of the sill component 2, located at the top of the anti-detachment component 3. The tops of the sill component 2 and the anti-detachment component 3 are fixedly installed via locking bolts 6 passing through the fixing groove 28. The sill 2 has an installation groove 25 on its outer side. The sill 25 is fixed to the anti-detachment component 3 by a locking bolt 6. Two sets of locking bolts 6 are used to fix the sill 2 and the anti-detachment component 3 from different positions, ensuring the stability of their installation. A support frame 4 is located between the anti-detachment components 3. The top of the support frame 4 is fixed to the sill 2 by multiple sets of locking bolts 6, and the support frame 4 is fixed to the elevator car floor 1 by multiple sets of butt bolts 5. The anti-detachment component 3 is fixedly installed to the elevator car floor 1. The bottom of the sill component 2 is fixedly installed to the support frame 4, and the support frame 4 is fixedly installed to the elevator car floor 1. The support frame 4 plays a role in bearing and fixing the sill component 2, and the top of the sill component 2 is limited and fixed to the anti-detachment component 3. When the sill component 2 is subjected to external force and detaches downward, it is limited by the snap-fit ​​between it and the limiting block 32 to prevent direct detachment. When subjected to force, the downward force compresses the anti-detachment component 3, and the shock-absorbing spring 33 prevents the anti-detachment component 3 from being compressed and deformed. The compression slope 35 compresses the connecting block 27, so that the sill component 2 and the elevator car floor 1 are tightly attached, reducing the possibility of the sill component 2 detaching.

[0028] First, fix the two sets of anti-detachment parts 3 to the elevator car floor 1. Then, install the anti-detachment part 3 onto the sill part 2 and fix it with the locking bolt 6. Finally, fix the support frame 4 on the elevator car floor 1 and lock its top to the sill part 2 with the locking bolt 6.

[0029] All technical features in this embodiment can be freely combined according to actual needs.

[0030] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
