Description

Technical Field

[0001] The utility model relates to the technical field of elevator load testing, and more specifically, to a device for testing elevator load. Background Art

[0002] The purpose of elevator load inspection is to ensure that the elevator can safely and effectively carry the set maximum load during operation to ensure the safety of passengers and equipment. Most of the counterweight devices used for elevator load inspection use heavy weights, which are placed inside the car to detect the elevator load. However, this working method is very inconvenient for manual lifting, time-consuming and labor-intensive, and inconvenient for counterweight operations.

[0003] After searching, a Chinese patent with announcement number CN220618303U discloses an elevator load testing device. During use, the device only needs to be pushed into the elevator car through a roller, and the driving component can be rotated, and the lifting component can be driven to rotate synchronously through the transmission component, thereby driving the internal thread block to move downward, thereby driving the lifting plate to move downward, and the lower weight can be driven downward by the lifting component, so that the weight contacts the ground, and finally the auxiliary component is driven to separate from the lifting component through the adjustment component, and the device can be driven to move to the outside of the elevator car by pulling the pull handle, so that the weight can be left inside the elevator car, and the elevator can be tested, which has the advantage of being easy to use.

[0004] When the above-mentioned inspection device is in use, the weights are left inside the elevator car to inspect the elevator. When more weights are left inside the elevator car and the elevator car shakes, multiple weights are easy to move in the elevator car, which makes it inconvenient to recover multiple weights and the use effect is poor. Utility Model Content

[0005] In order to overcome the above defects of the prior art, the utility model provides an elevator load testing device, aiming to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an elevator load testing device, comprising a mounting frame, a storage frame and a plurality of weights, the bottom end of the storage frame is fixedly connected to the mounting frame, and the plurality of weights are movably arranged inside the storage frame, universal wheels are fixedly installed at the four corners of the bottom end of the mounting frame, a moving assembly is arranged inside the mounting frame, the moving assembly comprises a limit plate, two vertical cylinders, a screw rod and a sliding rod, the bottom ends of the two vertical cylinders are fixedly connected to the limit plate, and the top ends of the two vertical cylinders pass through the bottom end of the mounting frame, the top end of the screw rod is movably connected to the top end inside the mounting frame through a bearing, the top end of the sliding rod is fixedly connected to the top end inside the mounting frame, and the bottom ends of the sliding rod and the screw rod respectively pass through the two vertical cylinders.

[0007] Furthermore, a handle is fixedly sleeved on the screw rod, and the two vertical cylinders are both located at the bottom of the handle.

[0008] It can be seen that in the above technical solution, it is convenient to drive the screw rod to rotate.

[0009] Furthermore, the screw rod and the slide rod are both movably sleeved with limiting rings, and the bottom ends of the two limiting rings are fixedly connected to the two vertical cylinders respectively.

[0010] It can be seen that in the above technical solution, the two limit rings can limit the downward movement distance of the two vertical cylinders to prevent the vertical cylinders from moving out of the screw rod.

[0011] Furthermore, a protective cover is fixedly connected to the top end of the limiting plate, and the top end of the protective cover passes through the bottom end of the mounting frame.

[0012] It can be seen that in the above technical solution, the noise detector is conveniently protected.

[0013] Furthermore, a noise detector is movably provided inside the protective cover, and the noise detector is fixedly installed inside the mounting frame, and a baffle is movably provided on the top of the noise detector, and the baffle is fixedly installed inside the mounting frame.

[0014] Furthermore, a gasket is bonded to the inner bottom end of the storage frame, and the top end of the gasket is in contact with one of the weights.

[0015] It can be seen that in the above technical solution, the weights can be buffered to prevent loud noises from being generated when the weights are placed.

[0016] Furthermore, two connection frames are fixedly connected to the front side of the mounting frame, a push handle is fixedly connected between the two connection frames, and a placement component is provided on one of the connection frames, and the placement component includes an insert block, a column and a clamping column.

[0017] Furthermore, the bottom end of the column is fixedly connected to the plug block, one end of the clamping column is fixedly connected to the plug block, a plurality of clamping holes are provided on the two connection frames, and the other end of the clamping column extends into one of the clamping holes.

[0018] It can be seen that in the above technical solution, the paper sleeve is movably mounted on the column, and then the mounting frame is moved to the vicinity of the elevator car door to observe whether the paper is blown by the airflow. If the paper is seen shaking, it means that the sealing is not good enough, and good sealing can effectively prevent dust, debris and other foreign matter from entering the car. The plug block is moved horizontally to move the card column out of the card hole, and then the card column is inserted into the card holes at different heights as needed to facilitate the detection of the sealing of the elevator car door.

[0019] Technical effects and advantages of the utility model:

[0020] 1. The utility model drives the screw rod to rotate by turning the handle, and the screw rod can drive the limit plate to move downward and make the limit plate contact with the ground, so as to limit the mounting frame and prevent the mounting frame from moving in the elevator. Similarly, the mounting frame is pushed out of the elevator and multiple weights in the storage frame are taken out, which is convenient for recycling multiple weights and has a good use effect;

[0021] 2. In the utility model, when a corresponding number of weights are placed in the storage frame, the noise of the elevator under different loads is detected by the noise detector. At the same time, the gasket cushions the weights to prevent a loud noise when the weights are placed. When the limit plate moves upward, the limit plate can drive the protective cover to move upward and make the protective cover contact with the baffle. When not detecting, the noise detector can be protected by the protective cover and the baffle. The structure is simple and easy to use. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] Furthermore, a handle 705 is fixedly sleeved on the screw rod 703, and the two vertical cylinders 702 are located at the bottom of the handle 705, and limiting rings 706 are movably sleeved on the screw rod 703 and the sliding rod 704, and the bottom ends of the two limiting rings 706 are fixedly connected to the two vertical cylinders 702 respectively.

[0034] Furthermore, a protective cover 707 is fixedly connected to the top of the limit plate 701, and the top of the protective cover 707 passes through the bottom end of the mounting frame 1, a noise detector 5 is movably provided inside the protective cover 707, and the noise detector 5 is fixedly installed inside the mounting frame 1, a baffle 6 is movably provided on the top of the noise detector 5, and the baffle 6 is fixedly installed inside the mounting frame 1, a gasket 10 is bonded to the inner bottom end of the storage frame 2, and the top of the gasket 10 is in contact with one of the weights 3.

[0035] Among them, when a corresponding number of weights 3 are placed in the storage frame 2, the noise detector 5 is used to detect the noise of the elevator under different loads. At the same time, the gasket 10 buffers the weights 3 to prevent a loud noise from being generated when the weights 3 are placed. When the limit plate 701 moves upward, the limit plate 701 can drive the protective cover 707 to move upward and make the protective cover 707 contact with the baffle 6.

According to the load requirement of the elevator, multiple weights 3 are placed in the storage frame 2 in sequence, and then the handle 705 is turned to drive the screw rod 703 to rotate. Since one of the vertical cylinders 702 is threadedly connected with the screw rod 703, the sliding rod 704 cooperates with the other vertical cylinder 702 to limit the rotation of the limiting plate 701, so the screw rod 703 can drive the limiting plate 701 to move downward and make the limiting plate 701 contact with the ground, thereby limiting the mounting frame 1 to prevent the mounting frame 1 from moving in the elevator. Similarly, the mounting frame 1 is pushed out of the elevator, and the multiple weights 3 in the storage frame 2 are taken out, which is convenient for recycling the multiple weights 3 and has a good use effect. At the same time, the two limiting rings 706 can limit the downward movement distance of the two vertical cylinders 702 to prevent the vertical cylinder 702 from moving out of the screw rod 703.
