Description

Technical Field

[0001] This utility model relates to a car bottom balance detection device, and more particularly to a high-speed freight elevator car bottom visual balance detection device. Background Technology

[0002] Freight elevators, also known as cargo elevators, are primarily designed for transporting goods vertically between floors in buildings. They can be categorized into small machine room elevators, machine room-less freight elevators, car elevators, and dumbwaiters. Freight elevators offer advantages such as high automation, smooth operation, safety, efficiency, convenience, and reliability, and are widely used in fields like electrical manufacturing and express logistics. Freight elevators are characterized by frequent transport and heavy loads. In existing high-speed freight elevators, the weight distribution within the car is more sensitive. Uneven cargo placement can cause the car to tilt, increasing the risk of accidents during operation. A tilted car can also lead to asynchronous braking of the elevator safety brakes, delayed braking, and damage to the cargo. Utility Model Content

[0003] The purpose of this invention is to provide a visual balance detection device for the bottom of a high-speed freight elevator. It has the function of timely detecting and providing feedback on the balance status of the elevator bottom, and can adjust the balance status in a timely manner, exhibiting high reliability.

[0004] The technical solution of this utility model is as follows: A high-speed freight elevator car bottom visual balance detection device, including a car support assembly, shock-absorbing components at four ends of the car support assembly, a car bottom plate on the upper side of the shock-absorbing components, and a car with a control panel and display panel on the upper side of the car bottom plate. The car support assembly includes two sets of horizontally and parallelly arranged car supports, two sets of horizontal and perpendicular crossbeams between the car supports, pads for installing shock-absorbing components at both ends of the car supports, a car bottom weighing component inside the pads, a tilt reset device in the car support, and a limiting device corresponding to the tilt reset device on the lower side of the car bottom plate.

[0005] In the aforementioned high-speed freight elevator car bottom visual balance detection device, the car support includes a top support beam and a bottom support beam that are parallel to each other.

[0006] In the aforementioned high-speed freight elevator car bottom visual balance detection device, the tilt reset device includes a hydraulic pump fixed to the bottom support beam by bolts and a mating seat provided on the top support beam. The mating seat has a protrusion in the middle corresponding to the hydraulic pump, and the upper edge of the protrusion has an arc-shaped transition section.

[0007] In the aforementioned high-speed freight elevator car bottom visual balance detection device, the limiting device is a bracket fixed to the lower side of the car bottom plate by bolts, and a limiting hole is provided in the middle of the lower end of the bracket.

[0008] Compared with the prior art, this utility model detects the weight distribution on the upper side of the car bottom using a car bottom weighing component and feeds the signal back to the control panel inside the car. The display panel can display the control panel information, and finally the car bottom is balanced by a tilting reset device, which improves reliability and safety. Attached Figure Description

Detailed Implementation

[0012] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.

[0013] Example. A high-speed freight elevator car bottom visual balance detection device, configured as follows: Figure 1-2 As shown, the system includes a car support assembly 1, with shock-absorbing components 2 at all four ends of the car support assembly 1, a car floor plate 3 on the upper side of the shock-absorbing components 2, and a car with a control panel and display panel on the upper side of the car floor plate 3. The car support assembly 1 includes two sets of horizontally and parallelly arranged car supports 7, with two sets of horizontal and perpendicular crossbeams 8 between the car supports 7, pads 9 for installing the shock-absorbing components 2 at both ends of the car supports 7, a car floor weighing component 10 on the inner side of the pads 9, a tilting reset device in the car supports 7, and a limiting device corresponding to the tilting reset device on the lower side of the car floor plate 3.

[0014] The car support 7 includes a top support beam 13 and a bottom support beam 14 that are parallel to each other.

[0015] The tilting reset device includes a hydraulic pump 11 fixed to the bottom support beam 14 by bolts and a mating seat 12 provided on the top support beam 13. The mating seat 12 has a protrusion 15 in the middle corresponding to the hydraulic pump 11, and the upper edge of the protrusion 15 has an arc-shaped transition section 18.

[0016] The limiting device is a bracket 16 fixed to the lower side of the car floor 3 by bolts, and a limiting hole 17 is provided in the middle of the lower end of the bracket 16.

[0017] The principle of this utility model: This application achieves a good shock absorption effect on the elevator by setting a shock-absorbing component 2. However, during elevator operation, the uneven weight distribution of people and goods in the car can easily lead to safety accidents and pose a significant safety hazard. This application installs a weighing component in the car support 7 to detect the weight at each end of the car floor 3. The weight information can be fed back to the control panel and display panel inside the car. Then, by activating the tilt reset mechanism, the car floor is kept in a balanced state, resulting in better safety. The hydraulic pump 11 on the upper side of the bottom support beam 14 cooperates with the mating seat 12 on the top support beam 13 to provide different support forces according to the stress on the car floor 3. A limiting device is provided under the car floor 3, which can cooperate with the mating seat 12 to keep the car balanced, thus improving reliability and safety.
