Description

Technical Field

[0001] This utility model relates to the field of elevator base technology, specifically a high-strength commercial elevator base. Background Technology

[0002] High-strength commercial elevator bases are elevator bases designed specifically for commercial use. They are made of high-strength materials and advanced manufacturing processes to ensure stability and durability in high-load, frequent-use commercial environments.

[0003] In existing technologies, the cushioning capacity and durability of elevator bases are improved by setting a buffer component at the bottom. However, the traction machine is set on the top of the elevator base. In existing devices, the traction machine is often fixed by welding it to the base. When the traction machine malfunctions or requires regular maintenance, it may be difficult to inspect and repair it. Due to the difficulty of maintenance, wear and loosening inside the traction machine may not be dealt with in time, resulting in greater vibration and noise during elevator operation. Therefore, we propose a high-strength commercial elevator base. Utility Model Content

[0004] The purpose of this invention is to provide a high-strength commercial elevator base to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-strength commercial elevator base, comprising an upper base and a lower base. A traction machine is installed on the top of the upper base, and a traction sheave is installed on the side of the top of the upper base near the traction machine. A clamping assembly is installed on the side of the top of the lower base near the upper base. The clamping assembly includes a slide rail, a lead screw is rotatably connected inside the slide rail, a first slider is threaded onto the lead screw, the first slider is slidably connected inside the slide rail, a motor is installed on the side of the slide rail near the lead screw, an extension rod is connected to the top of the first slider, a sliding rod is slidably connected to the top of the extension rod, a fixed rod is connected to the side of the sliding rod near the upper base, and a clamping plate is fixedly connected to the side of the fixed rod away from the sliding rod.

[0006] In a preferred embodiment, a first slide groove is provided on the side of the upper base near the clamping plate, a protrusion is provided in the first slide groove, a button is provided on the side of the protrusion near the clamping plate, and a detector is provided on the top of the lower base.

[0007] The above technical solution involves setting a button that is fully engaged with the clamping plate under normal conditions. When the clamping plate becomes loose, it will separate from the button, prompting the detector to issue a command to stop the elevator for maintenance.

[0008] In a preferred embodiment, a fixing component is provided on the top of the lower base near the detector. The fixing component includes a rotating shaft, on which a torsion spring is provided, and a limit plate is rotatably connected.

[0009] The above technical solution is adopted: by setting a fixing component, the detector is fixed to the top of the lower base.

[0010] In a preferred embodiment, a buffer assembly is provided on the top of the lower base. The buffer assembly includes a fixed base, a crossbar connected to the fixed base, a sliding member slidably connected to the crossbar, a spring connected to the sliding member, a connecting rod rotatably connected to the top of the sliding member, a second slider connected to the top of the connecting rod, and a second groove opened on the bottom of the upper base near the second slider, with the second slider slidably connected in the second groove.

[0011] The above technical solution improves the buffering capacity of the elevator base by connecting the upper and lower seats with a buffer assembly, thus ensuring the smooth operation of the elevator.

[0012] In a preferred embodiment, three buffer components are provided, and the three buffer components are respectively located between the bottom of the upper base and the top of the lower base.

[0013] The above technical solution is adopted to increase the stability of the connection between the upper and lower base by setting three buffer components.

[0014] In a preferred embodiment, a support seat is provided on the top of the upper machine base near the traction sheave, and a bolt is threadedly connected between the support seat and the upper machine base, with a nut threaded onto the bolt.

[0015] The above technical solution is adopted: a support base is set up and fixed to the top of the upper machine base with bolts and nuts, and the traction sheave is fixedly connected to the support base.

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

[0017] In this invention, a clamping assembly is provided to clamp and fix the traction machine, which is easy to disassemble and facilitates regular maintenance. When the clamping assembly becomes loose, the detector will issue a command to stop the elevator operation for inspection. This solves the problem in the prior art where a buffer assembly is set at the bottom of the elevator base to improve the buffering capacity and increase durability. However, the traction machine is set at the top of the elevator base, and in existing devices, it is often fixed by welding the traction machine to the base. When the traction machine malfunctions or requires regular maintenance, it may be difficult to inspect and repair it. Due to the difficulty of maintenance, wear and loosening inside the traction machine may not be dealt with in time, resulting in greater vibration and noise during elevator operation. By connecting the upper and lower bases with a buffer assembly, the buffering capacity of the elevator base is improved, ensuring the smooth operation of the elevator. Attached Figure Description

[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] like Figures 1-3 As shown, a high-strength commercial elevator base includes an upper base 1 and a lower base 2. A traction machine 3 is mounted on the top of the upper base 1, and a traction sheave 4 is mounted on the side of the upper base 1 closest to the traction machine 3. A clamping assembly 5 is mounted on the side of the lower base 2 closest to the upper base 1. The clamping assembly 5 includes a slide rail 51, a lead screw 52 rotatably connected within the slide rail 51, and a first slider 53 threadedly connected to the lead screw 52. The first slider 53 is slidably connected within the slide rail 51. A motor is mounted on the side of the slide rail 51 closest to the lead screw 52. An extension rod 54 is connected to the top of the first slider 53, and a sliding rod 55 is slidably connected to the top of the extension rod 54. A fixing rod 56 is connected to the side of the sliding rod 55 closest to the upper base 1, and a clamping plate is fixedly connected to the side of the fixing rod 56 furthest from the sliding rod 55. 57. A first slide groove 6 is provided on the side of the upper base 1 near the clamping plate 57. A protrusion 58 is provided in the first slide groove 6. A button 59 is provided on the side of the protrusion 58 near the clamping plate 57. A detector 12 is provided on the top of the lower base 2. When the motor is turned on, the lead screw 52 rotates in the slide rail 51. The lead screw 52 drives the first slider 53 to slide in the slide rail 51. The first slider 53 drives the extension rod 54 and the top sliding rod 55 to move to the side of the upper base 1, thereby driving the clamping plate 57 to clamp and fix the upper base 1 and the traction machine 3 on top, and to facilitate disassembly and maintenance. When the clamping component 5 becomes loose, the clamping plate 57 and the button 59 will no longer be in contact, and the detector 12 will issue a command to stop the elevator and carry out maintenance.

[0031] Furthermore, such as Figure 1 As shown: A support base 9 is provided on the top of the upper machine base 1 near the traction sheave 4. A bolt 10 is threadedly connected to the upper machine base 1, and a nut 11 is threadedly connected to the bolt 10. By setting up the support base 9, the bolt 10 and nut 11 are used to fix it to the top of the upper machine base 1, and the traction sheave 4 is fixedly connected to the support base 9.

[0032] The above solutions also have the problem that vibrations occur when the elevator stops, and the lack of a buffer structure between the upper platform 1 and the lower platform 2 can easily lead to swaying. Figure 4As shown: A buffer assembly 8 is provided on the top of the lower base 2. The buffer assembly 8 includes a fixed base 81, a crossbar 82 connected to the fixed base 81, a sliding member 83 slidably connected to the crossbar 82, a spring 84 connected to the sliding member 83, a connecting rod 85 rotatably connected to the top of the sliding member 83, and a second slider 86 connected to the top of the connecting rod 85. A second groove 87 is provided on the bottom of the upper base 1 near the second slider 86. The second slider 86 is slidably connected in the second groove 87. When vibration occurs, the sliding member 83 will slide on the crossbar 82, thereby compressing the spring 84, thereby driving the connecting rod 85 at the top to move. The connecting rod 85 drives the second slider 86 to slide in the second groove 87, thereby absorbing the impact force generated by vibration and keeping the base stable.

[0033] The above solution also has the problem that the detector 12 cannot be fixed on the top of the lower base 2, such as Figure 4 As shown: A fixing component 7 is provided on the top of the lower base 2 near the detector 12. The fixing component 7 includes a rotating shaft 71, a torsion spring 72 is provided on the rotating shaft 71, and a limit plate 73 is rotatably connected to the torsion spring 72. By setting the fixing component 7, the detector 12 is fixed on the top of the lower base 2.

[0034] Furthermore, such as Figure 4 As shown: There are three buffer components 8. The three buffer components 8 are located between the bottom of the upper base 1 and the top of the lower base 2. By setting three buffer components 8, the stability of the connection between the upper base 1 and the lower base 2 is increased.

[0035] Working principle: such as Figure 1 - Figure 4 As shown, firstly, the support base 9 is fixed to the top of the upper base 1 using bolts 10 and nuts 11. Then, the traction wheel 4 is fixed between the support bases 9. Subsequently, the motor is turned on to drive the lead screw 52 to rotate in the slide rail 51. The lead screw 52 drives the first slider 53 to slide in the slide rail 51. The first slider 53 drives the extension rod 54 and the top sliding rod 55 to move to one side of the upper base 1, thereby driving the clamping plate 57 to clamp and fix the upper base 1 and the traction machine 3 on top, which facilitates disassembly and maintenance. When the clamping assembly 5 becomes loose, the clamping plate 57 and the button 59 will no longer be in contact, and the detector 12 will issue a command to stop the elevator and carry out maintenance. When the elevator descends and vibrates, the sliding member 83 will slide on the crossbar 82, thereby compressing the spring 84, thereby driving the top connecting rod 85 to move. The connecting rod 85 drives the second slider 86 to slide in the second slide groove 87, thereby absorbing the impact force generated by the vibration and keeping the base stable. The sliding rod 55 is designed to work with the upper base 1 so that when it retracts, the sliding rod 55 retracts synchronously within the extension rod 54.

Although the present utility model has been disclosed above with reference to preferred embodiments, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-described technical content to create equivalent embodiments without departing from the scope of the present utility model.
